DETAIL DESCRIPTIONS OF THE INVENTION

(21) All illustrations of the drawings are for the purpose of describing selected versions of the present invention and are not intended to limit the scope of the present invention.

(22) The present invention is a modular tool apparatus is a portable hand tools that combines one or several individual functions in a single unit. More specifically, the present invention allows the user to foldably store and rotatably remove a tool component for repair or replacement.

(23) The present invention comprises at least one handle 1, at least one utility tool 2, at least one attachment channel 7, at least one D-shaped pivot pin 14, and at least one lever 18 as shown in FIG. 1-4. In reference to the general configuration of the present invention, the D-shaped pivot pin 14 is rotatably connected to the handle 1 so that the D-shaped pivot pin 14 is able to function as the primary connecting component between the handle 1 and the utility tool 2. The lever 18 being terminally connected to the D-shaped pivot pin 14 thus enabling the rotational movement of the D-shaped pivot pin 14 about the handle 1. The attachment channel 7 laterally traverses into the utility tool 2 and provide a void within the utility tool 2 so that the attachment channel 7 can be rotatably engaged around the D-shaped pivot pin 14. As a result, the utility tool 2 is foldably attached to the handle 1 through the attachment channel 7 and the D-shaped pivot pin 14. In other words, the utility tool 2 can be foldably stored within the handle 1 for storage purpose or can be foldably extended out of the handle 1 to usage.

(24) The utility tool 2 can include, but is not limited to, a screwdriver, a ruler, a metal or wood filer, a knife blade, a saw blade, a can/bottle opener, and a scissor. In reference to FIG. 5, the utility tool 2 comprises a main body 3, a longitudinal axis 4, a fixed end 5, and a free end 6. The main body 3 delineate or complete the shape/configuration of the utility tool 2. For example, when the utility tool 2 is a knife blade, the main body 3 resembles a rigid body with a cutting edge. The fixed end 5 and the free end 6 are oppositely positioned of each other about the main body 3 as the longitudinal axis 4 of the utility tool 2 is extended through the fixed end 5 and the free end 6. The attachment channel 7 is positioned adjacent to the fixed end 5 thus enabling the utility tool 2 to be attached and operated about the D-shaped pivot pin 14. The free end 6 is positioned offset of the D-shaped pivot pin 14 so that the free end 6 can be rotated about the D-shaped pivot pin 14.

(25) The attachment channel 7 that is rotatably engaged around the D-shaped pivot pin 14 comprises a circular section 8 and a rectangular section 11 as shown in FIG. 6. The circular section 8 that allows the utility tool 2 to be rotated about the D-shaped pivot pin 14 is concentrically positioned onto the longitudinal axis 4 of the utility tool 2 and traverses through the main body 3. The rectangular section 11 that allows the utility tool 2 to be inserted in or removed from the D-shaped pivot pin 14 laterally traverses into the main body 3 and is extended into the longitudinal axis 4 of the utility tool 2.

(26) The circular section 8 comprises a first half 9 and a second half 10, and the rectangular section 11 comprises a first lengthwise edge 12 and a second lengthwise edge 13 as shown in FIG. 6-7. In reference to further explanation of the attachment channel 7, the first lengthwise edge 12 and the second lengthwise edge 13 are positioned parallel to each other. The first lengthwise edge 12 is tangentially positioned to the first half 9 as the first lengthwise edge 12 intersect the longitudinal axis 4 of the utility tool 2. The second lengthwise edge 13 is laterally intercepted about the second half 10, wherein a diameter 22 of the circular section 8 is larger than a distance 23 between the first lengthwise edge 12 and the second lengthwise edge 13. Resultantly, a chord of the circular section 8 extends beyond the second lengthwise edge 13 and positioned opposite of the first lengthwise edge 12.

(27) In reference to FIG. 8-9, a cross section of the D-shaped pivot pin 14 comprises an arc wall 15 and a straight wall 16 as the straight wall 16 is terminally connected to the arch wall. More specifically, end points of the straight wall 16 are terminally connected to end points of the arc wall 15 thus delineating the cross sectional profile of the D-shaped pivot pin 14. Furthermore, the arc wall 15 is a major arc so that the D-shaped pivot pin 14 is able to concentrically rotate within the circular section 8 without any misalignments. Furthermore, the D-shaped pivot pin 14 is only able to slide through the rectangular section 11 at a specific angle as the orientation and configuration of the D-shaped pivot pin 14 regulates the movement of the utility tool 2. In order to accomplish the movement of the D-shaped pivot pin 14 within the attachment channel 7, a height 24 of the arc wall 15 has to be smaller than the distance 23 between the first lengthwise edge 12 and the second lengthwise edge 13 wherein the height 24 of the arc wall 15 is perpendicularly positioned to the straight wall 16 and bisects the cross section of the D-shaped pivot pin 14 as shown in FIG. 11.

(28) The lever 18 enables the rotational movement of the D-shaped pivot pin 14 about the handle 1 so that the utility tool 2 can be engaged or disengaged from the handle 1. In reference to FIG. 10, the lever 18 comprises a longitudinal axis 21, a first end 19, and a second end 20. The first end 19 and the second end 20 are oppositely positioned of each other about the lever 18 as the longitudinal axis 21 of the lever 18 is extended though the first end 19 and the second end 20. The first end 19 is terminally connected to the D-shaped pivot pin 14 thus transferring the rotational movement of the lever 18 to the D-shaped pivot pin 14. The second end 20 allows the user to comfortably grasp the lever 18 so that the lever 18 can be rotated. The longitudinal axis 21 of the lever 18 is positioned parallel to the straight wall 16 of the D-shaped pivot pin 14 so that the D-shaped pivot pin 14 can be rotated to any specific angle about the handle 1, as the specific angle can range from 0-180 degrees. For example, when the second end 20 is positioned within the handle 1, the user can freely extend the utility tool 2 out of the handle 1 for usage or fold the utility tool 2 into the handle 1 for storage as the utility tool 2 is rotatably engaged around the D-shaped pivot pin 14. However, when the second end 20 is parallelly extended out of the handle 1, the user can extend the utility tool 2 perpendicular to the handle 1 for removal or insertion of the utility tool 2 as the rotation of the D-shaped pivot pin 14 enables the attachment channel 7 to slide in and out of the D-shaped pivot pin 14.

(29) In reference to FIG. 12-14, the attachment channel 7 and the D-shaped pivot pin 14 are configured into a first locked position thus enabling the usage of the utility tool 2 while the utility tool 2 is folded out of the handle 1. The first locked position allows the utility tool 2 to be utilized within the present invention as the utility tool 2 is fully extended out of the handle 1. More specifically, the arc wall 15 is concentrically encircled within the circular section 8 so that the D-shaped pivot pin 14 is able to rotate about the circular section 8 of the attachment channel 7. However, the straight wall 16 is angularly positioned to the second lengthwise edge 13 of the rectangular section 11. Due to the angular positioning of the straight wall 16, at least some parts of the arc wall 15 is continuously in contact with a connection point of the second half 10 and the second lengthwise edge 13. Due to the obstruction between the D-shaped pivot pin 14 and the connection point, the utility tool 2 can be rotatably secured around the D-shaped pivot pin 14 when the utility tool 2 is angularly positioned to the handle 1 during the folding process of the utility tool 2.

(30) In reference to FIG. 15-17, the attachment channel 7 and the D-shaped pivot pin 14 are configured into a second locked position thus enabling the rotational movement of the utility tool 2 out of the handle 1. The second locked position allows the utility tool 2 to be rotatably moved around the D-shaped pivot pin 14 as the utility tool 2 is folded in and out of the handle 1. More specifically, the arc wall 15 is concentrically encircled within the circular section 8 so that the D-shaped pivot pin 14 is able to rotate about the circular section 8 of the attachment channel 7. However, the straight wall 16 is positioned parallel to the second lengthwise edge 13 of the rectangular section 11 as the straight wall 16 is positioned offset to the second lengthwise edge 13 and positioned adjacent to the first lengthwise edge 12. Due to the positioning of the straight wall 16, the arc wall 15 is fully engaged within the first half 9 and the second half 10. Since the second lengthwise edge 13 is laterally intercepted about the second half 10, the utility tool 2 can be rotatably secured around the D-shaped pivot pin 14 when the utility tool 2 is positioned parallel to the handle 1 and extended out of the handle 1.

(31) In reference to FIG. 18-20, the attachment channel 7 and the D-shaped pivot pin 14 are configured into an unlocked position that allows the insertion and removal of the utility tool 2 while the utility tool 2 is folded out of the handle 1. More specifically, the arc wall 15 is concentrically encircled within the circular section 8 so that the D-shaped pivot pin 14 is able to rotate about the circular section 8 of the attachment channel 7. However, the straight wall 16 is positioned parallel to the second lengthwise edge 13 of the rectangular section 11 as the straight wall 16 is positioned coincident to the second lengthwise edge 13. Since the height 24 of the arc wall 15 is smaller than the distance 23 between the first lengthwise edge 12 and the second lengthwise edge 13 and the first lengthwise edge 12 is tangentially positioned to the first half 9, the utility tool 2 can be easily removed from the D-shaped pivot pin 14 when the utility tool 2 and the handle 1 are positioned perpendicular to each other.

(32) The present invention preferably comprises a leaf-spring locking mechanism which locks the utility tool in desired position. In other words, the leaf-spring locking mechanism locks the utility tool 2 when the utility tool 2 is folded within the handle 1 or fully extended out of the handle 1. The leaf-spring locking mechanism comprises a leaf spring platform, a first engagement teeth, a second engagement teeth, and an opening. More specifically, the leaf spring platform is terminally connected to the handle 1 and generally positioned adjacent to the D-shaped pivot pin 14. Furthermore, the connection between the handle 1 and the leaf spring platform delineates the opening in between the handle 1 and the leaf spring platform. The first engagement teeth and the second engagement teeth are oppositely positioned of each other about the utility tool 2 and connected to the main body 3. As a result, when the utility tool 2 is folded within the handle 1, the first engagement teeth is engaged within the opening thus locking the utility tool 2. However, when the utility tool 2 is outwardly rotated about the D-shaped pivot pin 14, a curved end of the utility tool 2 pushed down on the leaf spring platform and disengaged the first engagement teeth from the opening. Similarly, when the utility tool 2 is fully extended out of the handle 1, the second engagement teeth is engaged within the opening thus locking the utility tool 2. However, when the utility tool 2 is inwardly rotated about the D-shaped pivot pin 14, the curved end of the utility tool 2 pushed down on the leaf spring platform and disengaged the second engagement teeth from the opening. Even though the present invention utilizes the leaf-spring locking mechanism as the preferred locking mechanism, the present invention can utilize any other type of locking mechanisms that is known within the multitool industry.

(33) Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
