DETAILED DESCRIPTION OF THE INVENTION

1. Overall Structure and Design Philosophy

(19) The multi-implement hand tool of the present invention is designed around principles of mechanical efficiency, ergonomic comfort, and functional versatility. The device comprises a primary wand-like handle that extends approximately 24-36 inches (60-90 cm) in length, with a diameter of approximately 1.25 inches (3.2 cm) at the grip section. The wand can be constructed from lightweight yet durable materials such as aircraft-grade aluminum alloy (6061-T6), high-impact ABS plastic, or fiber-reinforced polymer composites.

(20) FIG. 1 shows the wand 104, the carousel 106, the handgrip 108, the trigger 110, and the selector 112.

(21) The wand structure incorporates three main sections: 1. Proximal Section (Handle)Contains the ergonomic grip and all control mechanisms including triggers, levers, and selector controls. 2. Medial Section (Shaft)Houses the internal mechanical linkage systems that transmit user inputs from the handle to the implement mechanisms at the distal end. 3. The distal section comprises the implement assembly or carousel 106) which contains the multiple end-effectors and the selection mechanism that allows the user to choose among them.

(22) The wand structure is common to all configurations of implements. For example, the same wand 104, trigger 110, handgrip 108, and selector 112 are used regardless of which implement is rotated or slid into position.

(23) While one embodiment includes four implements, additional implements such as a scraper or brush could be mounted on the carousel or rail, with corresponding control mechanisms adapted accordingly. For example, a scraper could be activated by an additional cable trigger, could be added. Such a scraper would engage in scraping material stuck to a floor away from the floor.

(24) The design philosophy emphasizes mechanical simplicity while maintaining functional complexity, utilizing principles of mechanical advantage to minimize the force required for operation. All mechanisms are designed to operate without electricity, using only mechanical energy provided by the user. The implement selection and operation systems utilize precision-engineered components such as springs, levers, cables, pulleys, and locking mechanisms to achieve smooth, reliable performance.

2. Implement Selection Mechanism

(25) The distal end of the wand houses the selection mechanism, the carousel 106, which can be configured as either a rotating carousel (rotary model) or a linear slide rail (sliding model). Both configurations allow the user quickly to switch among the provided implements without requiring disassembly or separate attachments. User selections and activation are transmitted to the distal end end of the want by means of cables. Cables are routed through the handle by low-friction guide tubes.

(26) The deployment trigger 110 is a control located on the handle's 104 underside, positioned for comfortable operation with the index finger. The trigger has a pull distance of approximately 0.5 inches (906.7 mm) and is spring-loaded to return to the undepressed position when released.

(27) Trigger SpringA compression spring with a spring constant of approximately 901 lbs/in (0.35 N/mm) that returns the trigger to the undepressed position when released.

(28) The actuator cable 114 is a flexible cable with a diameter of 0.04 inches (1 mm), housed within a low-friction sheath. The cable runs from the deployment trigger through the wand shaft to the deployment lever on an implement such as the dustpan.

(29) A series of small, low-friction guides positioned at strategic points along the wand shaft to minimize cable friction and ensure smooth operation.

(30) A small, spring-loaded latch located on the handle can be engaged to hold the trigger in the depressed position, keeping the dustpan deployed during use.

(31) 2.1. Rotary Selection Mechanism

(32) The rotary selection mechanism comprises a carousel 106 assembly that rotates around a central axis perpendicular to the wand's longitudinal axis. The carousel is housed within a cylindrical casing at the distal end of the wand, with dimensions of approximately 3 inches (7.6 cm) in diameter and 4 inches (10.2 cm) in length. The carousel 106 carries implements, such as a sticky foot 202, a broom and dustpan 203, and a pincer 204.

(33) As the carousel 106 rotates around its axle 210, it brings each of the plurality of implements into contact with the floor or other surface on which the implement is meant to operate, while the other implements are held away from contact.

(34) Components and Construction:

(35) Carousel HubA precision-machined cylindrical component with three equidistant mounting points for the implements, spaced 120 degrees apart around its circumference. The hub is constructed from high-strength polymer or anodized aluminum with a diameter of approximately 2 inches (5.1 cm).

(36) Central AxleA hardened steel shaft with a diameter of 0.375 inches (9.5 mm) that serves as the rotation axis for the carousel. The axle is mounted within two sealed ball bearings at either end to ensure smooth rotation.

(37) Precision Ball BearingsTwo ABEC-5 rated sealed ball bearings with inner diameter of 0.375 inches (9.5 mm) and outer diameter of 0.875 inches (22.2 mm) support the central axle, providing low-friction rotation and long-term durability. The bearings are press-fit into recesses within the distal housing.

(38) Indexing WheelA thumb-operated wheel located on the side of the wand's distal section, approximately 3 inches (7.6 cm) from the end. The wheel has a diameter of 1.25 inches (3.2 cm) and features a textured or knurled edge for improved grip. The wheel is mechanically linked to the carousel hub through a gear reduction system that provides a 3:1 ratio, allowing precise control of the rotation. FIG. 2B depicts the 1 carousel hub 208, with its axle 210 and ball bearings 212.

(39) Gear Reduction SystemComprises a smaller pinion gear attached to the indexing wheel and a larger spur gear connected to the carousel hub. The gears are precision-cut with a module of 0.5 and are constructed from wear-resistant polyoxymethylene (POM) or metal. The pinion gear features 10 teeth while the spur gear has 30 teeth, creating a 3:1 reduction ratio that provides mechanical advantage and precise control. FIG. 2D depicts the detent wheels 214, with its larger first gear 1 228 and smaller second gear 2 230 and its actuator cable 232.

(40) Spring-Loaded Locking MechanismA spring-loaded detent system that secures the carousel in each of the three implement positions. FIG. 2C depicts the detent wheels 214 with its spring loaded locking mechanism comprising a first notches 216, a second notch 218, a third notch 220, a hardened steel ball bearing 222 held into a notch by a spring 224 and releasable by a release button 226. The mechanism consists of: An indexing detent wheel 214 with three precision-machined notches corresponding to the three implement positions. A hardened steel ball bearing 222 (0.25 inches/6.35 mm diameter) pressed against the detent wheel 214 by a compression spring 224. A compression spring 224 with a spring constant of approximately 3.5 lbs/in (0.61 N/mm) that provides sufficient force to hold the mechanism in place during use but allows manual rotation when desired. A release button 226 located adjacent to the indexing detent wheel that, when pressed, partially retracts the ball bearing from the detent wheel, reducing resistance during rotation.

(41) Cable attachment point 1 234 and cable attachment point 2 236 permits force to be transmitted from the actuator cable 232 to the opening cable 308 and the closing cable 408 for each of the implements.

(42) Operation:

(43) To change implements using the rotary selection mechanism, the user: 1. Presses the release button with his thumb to disengage the locking mechanism. 2. Rotates the indexing wheel with his thumb or finger to turn the carousel until the desired implement is in the active position. 3. Releases the release button, allowing the spring-loaded ball bearing to engage with the corresponding detent notch, securing the implement in place.

(44) The gear reduction ratio ensures that a complete 120-degree rotation of the carousel (to move from one implement to the next) requires a 360-degree rotation of the indexing wheel, providing precise control and reducing the likelihood of overshooting the desired position.

(45) 2.2 Sliding Selection Mechanism

(46) An alternative sliding selection mechanism utilizes a linear track system where the implements are stacked in parallel and can be slid into the active position. This configuration results in a more elongated but narrower profile at the distal end, with dimensions of approximately 1.75 inches (4.4 cm) width, 2 inches (5.1 cm) height, and 5 inches (12.7 cm) length.

(47) The implements are held in their closed position when not deployed, to permit them to pass each other as one is deployed and another removed from operation.

(48) Components and Construction:

(49) Linear TrackA precision-machined track system comprising two parallel rails with a T-slot profile. The rails are constructed from hardened steel or anodized aluminum and extend for approximately 4 inches (10.2 cm) along the distal section of the wand. The track width is approximately 1.5 inches (3.8 cm).

(50) Implement CarriersThree sliding carriers that mount the implements to the track system. Each carrier features T-shaped runners that engage with the track slots, ensuring smooth, guided movement. The carriers are constructed from low-friction polymer material such as PTFE-infused nylon.

(51) Grooved DetentsThree precision-machined notches in a detent bar that runs parallel to the track. Each notch corresponds to a position where one of the implements is aligned with the active position. The detents are machined to a depth of approximately 0.125 inches (3.2 mm) with angled entry and exit slopes to facilitate smooth engagement and disengagement.

(52) Push-Pull LeverA lever mechanism located on the side of the wand's distal section, approximately 4 inches (10.2 cm) from the end. The lever extends approximately 0.75 inches (19 mm) from the wand and can be moved forward and backward along a 2-inch (5.1 cm) slot. The lever is connected to the implement carrier assembly. FIG. 10B depicts the four push-pull levers, 1154, 1156, 1158, and 1160, each connected to one implement.

(53) Spring-Loaded Locking MechanismA spring-loaded pin that engages with the grooved detents to secure the selected implement in place. The mechanism consists of: A hardened steel pin with a diameter of 0.125 inches (3.2 mm) and a rounded tip. A compression spring with a spring constant of approximately 2.5 lbs/in (0.44 N/mm). A release trigger located adjacent to the push-pull lever that, when pressed, retracts the locking pin from the detent groove.
Operation:

(54) To change implements using the sliding selection mechanism, the user: 1. Presses the release trigger with their index finger to disengage the locking pin from the current detent groove. 2. Moves the push-pull lever forward or backward to slide the implement assembly until the desired implement is in the active position. 3. Releases the release trigger, allowing the spring-loaded pin to engage with the corresponding detent groove, securing the implement in place.

(55) The push-pull lever provides a 1:1 movement ratio with the implement assembly, allowing direct and intuitive control of the positioning. The detent system ensures positive engagement and prevents accidental movement during use.

3. Broom-and-Dustpan Implement

(56) The broom-and-dustpan implement provides a compact yet effective solution for sweeping and collecting small debris. This implement is designed to fold compactly when not in use and deploy into an operational configuration when selected.

(60) FIG. 3B depicts the broom component, which comprises a bristle head 312 and angled synthetic bristles 314.

(61) The bristle head 312 is a rectangular head measuring approximately 3 inches (7.6 cm) wide by 1.5 inches (3.8 cm) deep, constructed from durable ABS plastic or similar polymer. The head is permanently mounted to the implement carrier.

(62) The angled synthetic bristles 314 are synthetic bristles made from nylon or polyester, measuring approximately 1.25 inches (3.2 cm) in length. The bristles are arranged in a pattern of 16-20 tufts per square inch, with each tuft containing 25-30 individual bristles. The bristles are angled at approximately 15 degrees from vertical in the direction of the dustpan to enhance debris collection efficiency.

(63) The bristle head is permanently mounted to the implement carrier through a rigid connection that maintains the proper orientation relative to the dustpan.

(64) 3.2. Dustpan Component

(65) Components and Construction:

(66) The dust pan 304 is a rectangular platform measuring approximately 3.5 inches (8.9 cm) wide by 2 inches (5.1 cm) deep, with raised edges on three sides to contain collected debris. The platform is constructed from lightweight, durable ABS plastic or similar polymer with a thickness of approximately 0.1 inches (2.5 mm).

(67) The folding hinge 316 and the second arm 302 connect the dustpan platform to the implement carrier. The hinge features a hardened steel pin with a diameter of 0.125 inches (3.2 mm) running through interlocking leaves of the hinge. The hinge is designed to allow the dustpan to fold flat against the wand when not in use and extend perpendicular to the wand when deployed.

(68) The torsion spring 224 wraps around the hinge pin and biases the dustpan toward the folded position. The spring is constructed from spring steel wire with a diameter of 0.04 inches (1 mm) and provides approximately 0.5 lb-in (0.06 N-m) of torque.

(69) The extension arm is a second arm 302 connecting the deployment lever to the dustpan platform. The arm is constructed from steel wire with a diameter of 0.08 inches (2 mm) and transfers force from the deployment mechanism to overcome the torsion spring and extend the dustpan.

(70) Deployment Lever-A small lever located on the underside of the implement carrier that connects to the extension arm. The lever pivots around a fulcrum point and is acted upon by the cable from the handle control.

(71) Operation:

(72) To use the broom-and-dustpan implement: 1. The user selects the broom-and-dustpan implement using either the rotary or sliding selection mechanism. 2. The user pulls the deployment trigger on the handle, which pulls the cable and activates the deployment lever. 3. The deployment lever overcomes the torsion spring force and extends the dustpan to its operational position, perpendicular to the wand. 4. The user can engage the latch mechanism to keep the dustpan deployed without maintaining pressure on the trigger. 5. The user manually sweeps debris into the dustpan using the broom bristles. 6. When finished, the user releases the latch and trigger, allowing the torsion spring to return the dustpan to its folded position.

(76) The pivot point 412 is a precision-machined joint that allows the jaw arms to pivot around a central axis. The joint consists of a hardened steel pin with a diameter of 0.25 inches (6.35 mm) that passes through aligned holes in the jaw arms and the implement carrier.

(77) Rubberized gripping pads 414 are molded thermoplastic elastomer (TPE) pads with a Shore A hardness of approximately 65, attached to the inner surfaces of the jaw arms. The pads feature a textured surface with ridges and grooves to enhance gripping capability. Each pad measures approximately 2 inches (5.1 cm) long by 0.75 inches (19 mm) wide. FIG. 4 shows the pad 414 only on the first arm, but it is understood that identical pads are attached to both gripper arms.

(78) Spring-Assisted Return MechanismA torsion spring 406 attached between the proximal end of the first arm 401 and the second second arm 302 biases the jaw arms toward the open position. The spring is constructed from spring steel wire with a diameter of 0.05 inches (1.27 mm) and provides approximately 1.2 lb-in (0.14 N-m) of torque.

(79) Cable Attachment PointsSmall, reinforced loops or hooks on the internal sides of the jaw arms where the actuation cables attach. These points are positioned to provide maximum mechanical advantage when the cables are pulled.

(80) 4.2. Cable Actuation System

(109) Actuation TabA small tab at the free end of the lever arm that the user can press to activate the detachment function.

(110) Separating EdgeThe underside of the lever arm features a thin, wedge-shaped edge that slides between the adhesive surface and the picked-up item when the lever is activated, initiating separation.

(111) 5.3. Release Mechanism

(112) Components and Construction:

(113) Manual Sliding Release Ba-A slim bar located on the edge of the wand near the adhesive foot implement. The bar slides along a 1-inch (25.4 mm) track and is connected to the detachment lever via a simple linkage.

(114) Linkage SystemA mechanical linkage that transfers the sliding movement of the release bar to the actuation tab of the detachment lever. The linkage consists of:

(115) A small connecting rod with ball joints at each end to accommodate the pivoting movement of the adhesive pad.

(116) A transfer lever that changes the direction of force application from the sliding motion of the release bar to the pushing motion required for the detachment lever.

(117) Guide ChannelA channel molded into the implement carrier that guides the movement of the linkage components and ensures smooth operation.

(118) Operation:

(119) To use the adhesive foot implement: 1. The user selects the adhesive foot implement using either the rotary or sliding selection mechanism. 2. If necessary, the user removes the protective cover from the adhesive surface. 3. The user presses the adhesive pad against the target item (such as a piece of paper or lint). 4. The ball-and-socket joint allows the pad to pivot and achieve optimal contact with the surface. 5. The adhesive material adheres to the target item. 6. The user lifts the wand, bringing the adhered item with it. 7. To release the item, the user slides the release bar, which activates the detachment lever. 8. The detachment lever wedges between the adhesive surface and the item, breaking the adhesive bond and allowing the item to fall away. 9. If needed, the user can wash the adhesive surface with water to restore its tackiness.

6. Magnet Implement

(120) In one embodiment, the magnet 206 implement comprises a natural magnet that permits picking up metal objects. In another embodiment, the magnet implement comprises: a. An electromagnet; b. An integral battery; and c. An actuating circuit permitting a user to connect and disconnect the battery from the electromagnet, which circuit can be activated by the user from the proximate end of the handle.

(121) FIG. 6 illustrates the magnet implement 206. In some embodiments, the magnet implement 206 is accompanied by an integral battery 606 and an actuating circuit 608.

7. Handle Ergonomics and Control Integration

(122) The handle of the multi-implement hand tool is designed for ergonomic comfort, intuitive operation, and efficient control of all implement functions. The handle integrates multiple control mechanisms while maintaining a comfortable grip and optimal balance.

(123) 7.1. Handle Design and Materials

(124) Components and Construction:

(125) Core StructureA rigid central core constructed from lightweight aluminum alloy or high-strength polymer, providing structural integrity and housing for the internal control mechanisms.

(126) Contoured GripAn ergonomically contoured grip section that conforms to the natural curvature of the human hand. The grip features:

(127) A palm swell that fills the hollow of the user's palm, distributing pressure evenly. Finger indentations that guide finger placement for optimal control access.

(128) A thumb rest positioned for comfortable reach to the implement selection controls.

(129) Non-Slip SurfaceA layer of thermoplastic elastomer (TPE) with a Shore A hardness of approximately 60, overmolded onto the grip section. The surface features a textured pattern of small raised dots or ridges that enhance grip security, especially when wet or soiled.

(130) Weight Distribution-Strategic placement of internal components to achieve a balance point approximately 8 inches (20.3 cm) from the proximal end of the handle, providing optimal control and reduced user fatigue during extended use.

(131) 7.2. Central Control Hub

(132) Components and Construction:

(133) Control HousingA compact housing located at the forward section of the handle that contains and organizes all control mechanisms. The housing is constructed from impact-resistant ABS plastic and measures approximately 3 inches (7.6 cm) in length by 1.5 inches (3.8 cm) in diameter.

(134) Control LayoutAn ergonomic arrangement of controls that places each implement's activation mechanism in a distinct, easily accessible position:

(135) The grabber implement's squeeze trigger occupies the primary finger position, where the index and middle fingers naturally rest.

(136) The broom-and-dustpan implement's deployment trigger is positioned on the underside of the handle, accessible with the index finger when shifted slightly.

(137) The adhesive foot implement's release bar is located on the side of the distal section, accessible with the thumb or forefinger depending on grip orientation.

(138) The implement selection controls (indexing wheel or push-pull lever) are positioned on the side of the distal section, accessible with the thumb or forefinger.

(139) Visual IndicatorsSmall, raised icons or color-coded sections molded into the handle that provide tactile and visual identification of each control's function.

(140) 7.3. Mechanical Linkage System

(141) Components and Construction:

(142) Cable Management SystemAn organized arrangement of cable pathways within the wand shaft that minimizes friction, prevents tangling, and ensures smooth operation of all cable-actuated functions, which tie the user controls to the grabber, broom-and-dustpan, and adhesive foot and to the sliding selection mechanism. The system includes: Dedicated channels for each cable, maintaining separation and preventing interference. Low-friction PTFE liners at critical contact points to reduce wear and operational resistance. Access points at strategic locations for maintenance and adjustment.

(143) Precision-Engineered PulleysA series of small pulleys within the handle and wand shaft that redirect cable movement and provide mechanical advantage where needed. The pulleys feature: Sealed ball bearings for smooth, low-friction rotation. Grooved perimeters that keep cables properly aligned during operation. Hardened steel axles that ensure long-term durability.

(144) Guide TubesRigid and semi-rigid tubes that house and protect the cables along their paths through the wand shaft. The tubes are constructed from low-friction materials such as PTFE or polyethylene and feature: Smooth internal surfaces to minimize friction. Sufficient rigidity to maintain their shape under load. Strategic flexibility at points where the wand may bend slightly during use.

(145) Tension Adjustment SystemUser-accessible adjustment points near the handle that allow fine-tuning of cable tension for each implement. The system includes: Small thumbscrews that increase or decrease cable tension. Lock nuts that secure the adjustment position once set. Visual indicators that show the current tension setting.

(146) I one embodiment, a single actuator cable 114 runs through the wand from the selector 112 to the carousel 106, as depicted in FIGS. 1, 2D, 3A, 4, 5, 6, 8, and 11A.

(147) In another embodiment, depicted in FIG. 7, the cable is looped around pulleys at both ends. illustrates the mechanism in that embodiment that selects the implement, comprising a carousel 701, a selector 702, a selector cable 703, a knob 706, a carousel pulley 708, and a selector pulley 710.

8. Synergistic Integration of Components

(148) The multi-implement hand tool is projected to achieve advantages through the synergistic integration of its components, creating a system that is more efficient and effective than separate, individual implements.

(149) 8.1. Implement Transition Efficiency

(150) The selection mechanism is designed to work in harmony with the implement activation controls, allowing rapid transitions between functions with minimal user effort. This integration includes: Neutral Control PositionsWhen switching between implements, all control mechanisms automatically return to neutral positions, preventing accidental activation during the transition. Implement Retraction SystemBefore rotation or sliding to a new implement position, any extended components (such as the dustpan) are automatically retracted by the mechanical interlocks, ensuring clearance for movement. Sequential Activation LogicThe mechanical design ensures that implement selection must be completed before implement activation can occur, preventing operational conflicts.
8.2. Mechanical Advantage Optimization

(151) The mechanical systems throughout the device are designed to provide optimal mechanical advantage for each function, reducing the force required from the user: Compound Leverage in Grabber SystemThe grabber's cable system utilizes a compound pulley arrangement that multiplies user input force by approximately 5:1, allowing firm gripping with minimal hand strain. Progressive Resistance in Deployment MechanismsThe dustpan deployment system incorporates a variable-rate spring that provides less resistance at the beginning of the deployment motion and increases resistance as the dustpan approaches full extension, creating a natural soft stop feel. Force Distribution in Adhesive PadThe pivoting mount for the adhesive pad automatically distributes pressure evenly across the adhesive surface when pressed against an object, maximizing adhesion with minimal user force.
8.3. Material Optimization

(152) The selection of materials throughout the device has been carefully optimized for each component's specific requirements: Wear-Resistant Contact SurfacesAll mechanical contact points susceptible to wear (such as pivot points, detent mechanisms, and sliding surfaces) are constructed from materials specifically chosen for their wear resistance properties, such as acetal homopolymer for sliding surfaces and hardened steel for high-stress pivot points. Fatigue-Resistant Flex PointsComponents that undergo repeated flexing (such as springs and cable guides) are constructed from materials with excellent fatigue resistance properties, such as spring steel alloys and specialty polymers with high flex-life ratings. Weight-Optimized Structural ElementsNon-load-bearing structural elements are constructed from lightweight materials such as reinforced polymers, while load-bearing components utilize higher-density materials such as aluminum alloys or steel, optimizing the balance between weight and strength.

(153) FIG. 8 system's operational connections, comprising the wand 104, the carousel 106, the actuator cable 114, a flexible link 830, connecting the first arm 301, and the second arm 302, of a selected implement 836. When tension is applied to the cable by depressing the trigger, the cable pulls the arms together, thus opening the implement, or closing it, depending on whether the cable is attached to the proximal ends of the arms, as shown, or to the distal ends of the arms.

9. Detailed Operation Sequences

(154) The following detailed operation sequences illustrate the precise mechanical interactions that occur during typical use scenarios of the multi-implement hand tool.

(155) 9.1. Implement Selection Sequence (Rotary Model)

(156) 1. InitiationThe user grips the handle with one hand and places his thumb on the indexing wheel.

(157) 2. Lock DisengagementThe user presses the release button adjacent to the indexing wheel with the side of his thumb, compressing the spring and partially retracting the detent ball from its current notch in the detent wheel.

(158) 3. RotationWhile maintaining pressure on the release button, the user rotates the indexing wheel with his thumb. The rotation is transferred through the pinion gear to the spur gear at a 3:1 ratio, causing the carousel hub to rotate.

(159) 4. Implement AlignmentAs the carousel rotates, the currently active implement moves out of the operational position, and another implement begins to move into position. The user continues rotating until the desired implement is aligned with the operational axis of the wand.

(160) 5. Lock EngagementWhen the desired implement reaches the operational position, the user releases the release button, allowing the compressed spring to push the detent ball into the corresponding notch in the detent wheel, securing the carousel in position with an audible click.

(161) 6. ConfirmationThe user visually or tactilely confirms that the desired implement is properly aligned and locked in the operational position before proceeding to use the implement.

(162) 9.2. Broom-and-Dustpan Operation Sequence

(163) 1. Implement SelectionThe user selects the broom-and-dustpan implement using either the rotary or sliding selection mechanism as described previously.

(164) 2. Dustpan DeploymentThe user pulls the deployment trigger on the handle with their index finger, creating tension in the deployment cable. As the cable tension increases: a. The cable pulls on the deployment lever located on the dustpan assembly. b. The deployment lever rotates around its fulcrum point, transferring force to the extension arm. c. The extension arm pushes against the dustpan platform, causing it to rotate around its hinge against the resistance of the torsion spring. d. The dustpan platform rotates approximately 90 degrees from its folded position to its deployed position, perpendicular to the wand.

(165) 3. Deployment Locking-If desired, the user engages the latch mechanism on the handle by sliding a small lever with their thumb while maintaining pressure on the deployment trigger. The latch engages with a notch on the trigger, holding it in the depressed position and keeping the dustpan deployed without continuous finger pressure.

(166) 4. Sweeping OperationThe user positions the implement with the broom bristles in contact with the surface containing the debris and the deployed dustpan positioned to receive the swept debris. Using short, controlled strokes, the user sweeps the debris toward and into the dustpan.

(167) 5. Debris RetentionThe raised edges on three sides of the dustpan platform contain the collected debris, preventing it from falling out during the lifting process.

(168) 6. Dustpan RetractionAfter collecting the debris, the user disengages the latch mechanism (if engaged) by pressing a release button, allowing the deployment trigger to return to its undepressed position. As the trigger returns: a. Tension is released from the deployment cable. b. The torsion spring in the dustpan hinge rotates the dustpan platform back to its folded position against the wand. c. The extension arm and deployment lever return to their rest positions.

(169) 7. Debris DisposalThe user positions the implement over a waste receptacle and briefly inverts it, allowing the collected debris to fall out of the dustpan.

(170) 9.3. Grabber Operation Sequence

(171) 1. Implement SelectionThe user selects the grabber implement using either the rotary or sliding selection mechanism as described previously.

(172) 2. Jaw Opening ConfirmationThe user visually confirms that the grabber jaws are in their fully open position, with the torsion spring maintaining maximum separation between the jaw arms.

(173) 3. Position for GraspingThe user positions the implement with the open grabber jaws on either side of the target object to be grasped.

(174) 4. Optional Ratchet EngagementIf the user anticipates needing to maintain the grip for an extended period, they engage the ratcheting lock mechanism by flipping its activation lever with their thumb before squeezing the trigger.

(175) 5. Jaw ClosingThe user squeezes the trigger on the handle with their fingers, initiating a sequence of mechanical actions: a. The trigger pivots around its fulcrum point, pulling on the primary lever within the handle. b. The primary lever pulls the grabber cables through the compound pulley system, which multiplies the input force by approximately A 5:1 ratio. c. The tension in the cables increases as they pull through their guide tubes along the length of the wand. d. At the grabber implement, the cables pull on the attachment points on the internal sides of the jaw arms. e. The pulling force causes the jaw arms to pivot around their central axis, overcoming the resistance of the torsion spring. f. The rubberized gripping pads on the jaw arms move toward each other and make contact with the target object.

(176) 6. Grip MaintenanceIf the ratcheting lock mechanism has been engaged, as the user squeezes the trigger: a. The pawl in the ratchet mechanism engages with the teeth of the rack. b. Each tooth that the pawl engages represents a discrete position at which the jaws can be held without continuous finger pressure. c. The user squeezes the trigger until sufficient gripping force is applied to the object, then releases finger pressure, allowing the pawl to maintain the jaw position.

(177) 7. Object ManipulationWith the object securely grasped by the grabber jaws, the user manipulates the implement to move, lift, or position the object as needed.

(178) 8. Jaw Opening and Object ReleaseTo release the grasped object, the user: a. If the ratcheting lock is not engaged, simply releases pressure on the trigger, allowing the torsion spring to open the jaw arms. b. If the ratcheting lock is engaged, presses the release button adjacent to the trigger, which disengages the pawl from the rack and allows the torsion spring to open the jaw arms.
9.4 Adhesive Foot Operation Sequence

(179) 1. Implement SelectionThe user selects the adhesive foot implement using either the rotary or sliding selection mechanism as described previously.

(180) 2. Protective Cover RemovalIf the protective cover is in place over the adhesive surface, the user removes it by gently pulling on its tab, exposing the adhesive material.

(181) 3. PositioningThe user positions the implement with the adhesive pad directly above the target item to be picked up, such as a piece of paper or lint.

(182) 4. Contact and AdhesionThe user lowers the implement until the adhesive pad makes contact with the target item: a. The ball-and-socket joint in the pivoting mount allows the pad to automatically adjust its angle to achieve optimal surface contact. b. The slight concave shape of the pad base helps create maximum contact area with flat objects. c. The silicone-based adhesive material adheres to the target item with sufficient force to lift it when the implement is raised.

(183) 5. LiftingThe user lifts the implement, bringing the adhered item with it, attached to the adhesive pad.

(184) 6. TransportThe user moves the implement with the adhered item to the desired location, such as a waste receptacle or new position.

(185) 7. Item ReleaseTo release the adhered item, the user slides the manual release bar on the side of the wand, initiating a sequence of mechanical actions: a. The sliding movement of the release bar is transferred through the linkage system to the actuation tab of the hinged detachment lever. b. As the actuation tab is pushed, the lever arm pivots around its hinge joint. c. The separating edge on the underside of the lever arm wedges between the adhesive surface and the adhered item. d. The wedging action breaks the adhesive bond, causing the item to fall away from the adhesive pad.

(186) 8. Adhesive MaintenanceIf the adhesive pad becomes less tacky due to accumulated debris or dust, the user can restore its adhesive properties by: a. Rinsing the pad with water. b. Gently wiping away any loose debris with a clean cloth. c. Allowing the pad to air dry completely before reuse.

(187) FIG. 9 illustrates a method for using the system, comprising: identifying the object 901, selecting the implement 902, positioning the implement proximate to the object 903, activating the implement to grab, sweep, or pick up 904, picking up the object 905, transferring it to a desired location 906, and, in some embodiments, activating the tool to release the object 907.

(188) Although the example routine depicts a particular sequence of operations, the sequence may be altered without departing from the scope of the present disclosure. For example, some of the operations depicted may be performed in parallel or in a different sequence that does not materially affect the function of the routine. In other examples, different components of an example device or system that implements the routine may perform functions at substantially the same time or in a specific sequence.

(189) 2.2 Sliding Selection Mechanism

(190) An alternative sliding selection mechanism utilizes a linear track system where the implements are stacked in parallel and can be slid into the active position. This configuration results in a more elongated but narrower profile at the distal end, with dimensions of approximately 1.75 inches (902.902 cm) width, 901 inches (5.1 cm) height, and 5 inches (906.7 cm) length.

(191) FIG. 10A illustrates the sliding selection mechanism, which comprises the sticky foot 202, the broom and dustpan 203, the pincer 204, the magnet 206, a sliding selector 1044, a track 1046 for each implement (the track for the sticky foot is shown), a sliding foot that holds each implement in its track (implement carrier 1 1050, and implement carrier 2 1052 are shown). illustrates the sliding selection mechanism

(192) The implements are held in their closed position when not deployed, to permit them to pass each other as one is deployed and another removed from operation.

(193) Components and Construction:

(194) Linear TrackA precision-machined track system comprising two parallel rails with a T-slot profile. The rails are constructed from hardened steel or anodized aluminum and extend for approximately 902 inches (905.901 cm) along the distal section of the wand. The track width is approximately 1.5 inches (3.904 cm).

(195) Implement CarriersThree sliding carriers that mount the implements to the track system. Each carrier features T-shaped runners that engage with the track slots, ensuring smooth, guided movement. The carriers are constructed from low-friction polymer material such as PTFE-infused nylon.

(196) Grooved DetentsThree precision-machined notches in a detent bar that runs parallel to the track. Each notch corresponds to a position where one of the implements is aligned with the active position. The detents are machined to a depth of approximately 0.125 inches (3.901 mm) with angled entry and exit slopes to facilitate smooth engagement and disengagement.

(197) Push-Pull LeverA lever mechanism located on the side of the wand's distal section, approximately 902 inches (905.901 cm) from the end. The lever extends approximately 0.75 inches (19 mm) from the wand and can be moved forward and backward along a 901-inch (5.1 cm) slot. The lever is connected to the implement carrier assembly.

(198) Spring-Loaded Locking MechanismA spring-loaded pin that engages with the grooved detents to secure the selected implement in place. The mechanism consists of: A hardened steel pin with a diameter of 0.125 inches (3.901 mm) and a rounded tip. A compression spring with a spring constant of approximately 901.5 lbs/in (0.44 N/mm). A release trigger located adjacent to the push-pull lever that, when pressed, retracts the locking pin from the detent groove.
Operation:

(199) To change implements using the sliding selection mechanism, the user: 1. Presses the release trigger with their index finger to disengage the locking pin from the current detent groove. 2. Moves the push-pull lever forward or backward to slide the implement assembly until the desired implement is in the active position. 3. Releases the release trigger, allowing the spring-loaded pin to engage with the corresponding detent groove, securing the implement in place.

(200) The push-pull lever provides a 1:1 movement ratio with the implement assembly, allowing direct and intuitive control of the positioning. The detent system ensures positive engagement and prevents accidental movement during use.

(201) FIG. 11A depicts one embodiment of the the manipulation enabler in which the spring 224 holds the implement normally open. When the trigger 110 is pulled, that increases the tension on the actuator cable 114 pulls the flexible link 828, and causes the first arm 301 and the second arm 302, to pilot around the pivot point 412, and close.

(202) In this first embodiment, each of the implements is spring loaded so that its normal position is open. For example, the normal position of the pincher is with its two fingers apart; the normal position of the broom and dust pan implement is with the broom and dust pan separated. Pulling on the trigger when the pincher is selected causes the fingers of the pincher to come together. Pulling on the trigger when the broom and dust pan implement is selected cause the broom to sweep toward the dust pan.

(203) FIG. 11B depicts an alternative embodiment of the manipulation enabler wherein a spring 1128 holds the implement in a normally closed position Pulling on the trigger, tensions the actuator cable 114, which pulls on a first lever 1124 and a second lever 1126, which action causes the first arm 301 and the second arm 302, connected through the pivot point 412, to separate, thus opening the implement.

(204) In this second embodiment, each of the implements is spring-loaded so that its normal position is closed. For example, the normal position of the pincher is with its two fingers together; the normal position of the broom and dust pan implement is with the broom and dust pan together; and the normal state of the magnetic implement is deenergized. When the user depresses the trigger, that motion pulls on the cable, which has various effects at the distal end, depending on the implement. FIG. 11B depicts how a cable pull has the effect of separating the broom and dust pan or of separating the fingers of the grab or implement to.

(205) Each implement needs only one attachment point for the cable.

(206) In the case of the magnetic complement, a pull on the cable results in connecting the battery, thus energizing the electromagnet.

10. Manufacturing Considerations

(207) The design of the multi-implement hand tool incorporates specific features that facilitate efficient manufacturing and assembly while maintaining high quality and reliability.

(208) 10.1. Modular Construction

(209) The tool is designed with a modular approach that allows for efficient manufacturing and assembly: Subassembly IntegrationMajor functional components (such as the implement selection mechanism, each implement, and the handle control systems) are designed as distinct subassemblies that can be manufactured and tested separately before final integration. Standardized InterfacesThe connections between subassemblies utilize standardized interfaces with precise tolerances, ensuring proper fit and function when assembled. Snap-Fit ComponentsWhere appropriate, components incorporate snap-fit connections that reduce the need for fasteners and accelerate assembly time while maintaining structural integrity. Service Access PointsThe design includes strategically located access points that allow for maintenance or repair of internal components without requiring complete disassembly of the tool. The design allows substitution of implements via standardized mounting points on the carousel or rail, accommodating user-specific needs like a scraper or brush, any of which can be installed easily.
10.2. Material Selection for Manufacturing

(210) Materials have been selected not only for their functional properties but also for their manufacturability: Injection-Moldable PolymersThe majority of the external housing and non-load-bearing components are designed to be injection molded from thermoplastic polymers such as ABS, polycarbonate, or glass-filled nylon, allowing complex shapes to be produced efficiently and consistently. Extrusion-Compatible MetalsThe wand shaft and other elongated structural components are designed to use extruded aluminum or other metals, which can be produced continuously and cut to length, reducing manufacturing costs. Cost-Effective Metal ComponentsLoad-bearing metal components such as pins, axles, and springs are designed to use standard sizes and grades of materials that are readily available and economical. Overmolding CompatibilityComponents requiring non-slip surfaces or enhanced ergonomics are designed with appropriate undercuts and bonding surfaces for efficient overmolding of thermoplastic elastomers (TPE).
10.3. Assembly Optimization

(211) The design incorporates features that facilitate efficient assembly: Unidirectional AssemblyComponents are designed to be assembled primarily from one direction, allowing for simplified assembly fixtures and reducing the need to reorient the product during assembly. Self-Aligning FeaturesCritical components incorporate chamfered edges, guide pins, or other self-aligning features that reduce the precision required during assembly and help prevent misalignment. Captive FastenersWhere threaded fasteners are necessary, the design incorporates captive fastener features that hold screws in place during assembly, reducing the chance of dropped or misplaced fasteners. Visual Assembly Indicators-Components that must be oriented in a specific way incorporate visual indicators such as color coding or asymmetrical shapes that make correct orientation immediately apparent.

11. Conclusion

(212) The multi-implement hand tool with user-selectable end effectors represents a significant advancement in hand-operated cleaning and retrieval implements. Through innovative mechanical design and thoughtful integration of multiple functions, the tool provides users with unprecedented versatility and efficiency in a single, compact device.

(213) The purely mechanical nature of the tool eliminates the need for batteries or electrical components, resulting in a product that is environmentally friendly, economical to manufacture, and highly reliable over an extended service life. The ergonomic design and optimized mechanical systems ensure that users of varying strength and dexterity can operate the tool effectively with minimal fatigue.

(214) The synergistic combination of the broom-and-dustpan, grabber, and adhesive foot implements in a single tool, along with the innovative selection mechanism, creates a product that is more than the sum of its partsa comprehensive solution for a wide range of cleaning and retrieval tasks that would otherwise require multiple separate implements.

(215) The integration of these specific implements reduces task-switching time by a projected 50% compared to separate implements, a synergy not suggested by prior art focused on single-function or detachable designs
