The handle, shoulder and spool can be formed as connected parts or as one unitary device. The slip sleeve can be secured in place so that it rotates around a portion of the handle up to and covering most of the shoulder. The torque transfer connection is integrated as either an internal hex bit receiver/adaptor, and/or external round or hexagonal bit.

[0021] The device may also include one or more of the following: hooks to secure string from unwinding and allowing the spooling tool to be suspended from the work area, a fixed exterior hex bit at the end of the spool; the exterior hex bit would provide a torque transfer connection from a hand held drill or impact driver type device, a fixed exterior rounded bit of a suitable diameter (i.e., a diameter) or less at the end of the spool used as a hand retrieval device, torque connection transfer location, or a simple handle without a slip sleeve. A removable torque transfer connection (i.e., hex bit) can be provided that fits within the interior hex bit receiver. The hex bit would in turn fit directly into the chuck of a handheld drill and/or impact driver. The exterior hex bit would provide a torque transfer connection from a handheld drill or impact driver type device.

[0022] A removable exterior rounded bit of or less can be designed to fit directly into the chuck of a handheld drill. The exterior rounded bit would provide a torque transfer connection from a handheld drill with standard chuck.

[0023] The handle may be sized or shaped to fit within a standard drill ( diameter or less) or have a hex shaped end.

[0024] The torque transfer connection may be centered on the handle end. The spooling end may have a solid handle for manual retraction or two hand deployment. The spooling end may have an integrated handle and torque transfer connection. The hex or round bit torque connection may be utilized for a variety of handheld spooling tools. Including chalk-line, measuring tape, kite string, or the like. An alternative mechanism includes holding a disposable spool via friction or other suitable means.

[0025] A spool can be configured with spring wire tensioners(s) that collapse under pressure into the spool core to hold tension onto the disposable spool. The spring wire tensioners(s) is designed to contract with spring-type action to secure a disposable spool and hold it in place on the device.

[0026] The slip sleeve may be held in place using a variety of ways including, but not limited to, a retaining clip, a handle ledge, and the like.

[0027] The hex bit torque receiver may be integrated and utilized within the winding mechanism of a chalk line tool. The hex bit torque receiver may be integrated and utilized within a measuring tape winding device. It may have an internal safety clutch configured to slip if the device or material is caught, for example on an object or operator. It may further have a removable locking shoulder that is securable to the spool.

[0028] The outside shoulder may have a part for manual winding. The manual winder is a part of the shoulder with a solid connection to the device spool. The manual winder is a protruding area of the shoulder for a finger winding operation where torque can be applied for string respooling. It may further have a loop or bowl-shaped winding mechanism that is permanent or removable.

[0029] In another example, the shoulder includes magnets. It may have an outside shoulder held with magnets or an outside shoulder held securely to the device spool with a locking mechanism. The outside shoulder held securely to the device spool with a locking mechanism and magnets. The locking mechanism can utilize a standard hex bit lock. The hex bit lock can be released by pulling a plunger in line with the hex bit. The plunger may have an outer lip flare to reduce the grip strength needed to operate the plunger.

[0030] In another example, the present disclosure provides for a split device spool having spring tensioners. It may have a split spool holder to accommodate various size replacement spool lengths. It may have a handle side spool holder and an outside shoulder spool holder held with spring tension to the spool core. The spring tensioners can be made from a variety of materials including metal and plastic or plastic like derivatives. The tension springs may be made as an integrated part of the spool holder. This may serve as a means of manufacturing cost reduction. If this is made as an integrated part as with injection mold or similar there may be great manufacturing cost reduction.

[0031] A spool holder can be configured with spring tensioners. The spring tensioners are sized to compress as the spool holder is inserted into the spool. The spring tensioner holds the inside of the string spool in place for torque transfer (from spool holder to spool) and maintains position between the handle/shoulder split sleeve and the spool. The sizing is such that the tool will universally fit within most standard spool cores in the 24 mm range.

[0032] The device may have a hex or other shaped axle to connect the handle spool holder and the shoulder spool holder. The shape of the axle is matched as a receiver on the shoulder spool holder. If the axle is a standard hex bit then the shoulder shall have a hole to receive and transfer torque between the two spool holders. It may further include a concave parabola funnel shaped receiver area to assist and guide with the insertion of a drill hex bit. In another example, it may have a funnel shaped receiver area to assist and guide with the insertion of a handle axle into the shoulder spool holder. The axle and receiver may switch locations. That is the axle may be attached to the handle and not the shoulder.

[0033] The device may include one spool holder longer than the other. The purpose of this configuration is to allow for maximum spool length variation. With the axle connected to the shorter spool holder and the longer spool holder acting as the axle receiver, the device can accommodate a common 107 mm spool (or shorter) up to a common 154 mm spool (or longer).

[0034] It may have an axle receiver that extends well into the handle. The longer the axle the greater variation in disposable spool size accommodation available with the device. The axle receiver may also act as a connecting dowel used in parts assembly.

[0035] The present disclosure provides for a hand powered or mechanical spooling device, which is made up of the following components: a spool, a torque transfer connection centered and torsionaly balanced on one end of the spooler, a handle, shoulder to keep string off handle, slip sleeve. The handle, shoulder and spool are connected as one solid unit. The slip sleeve is secured in place so that it rotates around a portion of the handle up to and covering most of the shoulder. The power torque transfer connection is integrated as either an internal hex bit receiver, external round or hexagonal bit.

[0036] The device may also have one or more of the following: hooks to secure string from unwinding and allowing the spooling tool to be suspended from the work area, a fixed exterior hex bit at the end of the spool; the exterior hex bit would provide a torque transfer connection from a hand held drill or impact driver type device, a fixed exterior rounded bit diameter or less at the end of the spool used as a hand retrieval device, torque connection transfer location, or a simple handle without a slip sleeve. A removable torque transfer connection (hex bit) that fits within the interior hex bit receiver. The hex bit would in turn fit directly into the chuck of a handheld drill and/or impact driver. The exterior hex bit would provide a torque transfer connection from a handheld drill or impact driver type device.

[0037] The present disclosure provides for a removable exterior rounded bit diameter or less designed to fit directly into the chuck of a handheld drill. The exterior rounded bi would provide a torque transfer connection from a handheld drill with standard chuck. The spooling end may have an integrated handle and torque transfer connection. The hex or round bit torque connection may be utilized for a variety of handheld spooling tools. Including chalk-line, measuring tape, kite string, etc.

[0038] The hex bit torque receiver may be integrated and utilized within the winding mechanism of a chalk line tool. The hex bit torque receiver may be integrated and utilized within a measuring tape winding device. It may have an internal safety clutch configured to slip if the device or material is caught.

[0039] The outside shoulder may include a manual winding feature. The manual winder feature can be configured as a protruding area of the shoulder for a finger winding operation where torque can be applied for string respooling. It may have a loop or bowl-shaped winding mechanism that it permanent or removable.

[0040] A magnetic shoulder may have an outside shoulder held with magnets. It may have an outside shoulder held securely to the device spool with a locking mechanism or have an outside shoulder held securely to the device spool with a locking mechanism and magnets. The locking mechanism utilizes a standard hex bit lock. The hex bit lock can be released by pulling a plunger in line with the hex bit. The plunger may have an outer lip flare to reduce the grip strength needed to operate the plunger.

[0041] Additional methods of joining the device spool to the shoulder not shown. One such method is to use a system similar to a common method of holding a socket to a ratchet tool. This method uses a compressed spring and round barring mechanism on a shaft. When the shaft is inserted into the socket sleeve receiver, the barring is forced into a divot. The marriage of the round barring and the divot form a solid connection.

[0042] Similarly, the associated method may also include one or more of the following steps:

[0043] While configured with an exterior hex bit the operator would insert the hex bit directly into the chuck of a drill or impact driver. While configured with an exterior rounded bit the operator or would insert the rounded bit directly into the chuck of a drill.

[0044] The disclosed device is unique when compared with other known devices and solutions because it provides: (1) a mechanism to acquire torque from a hand held power tool like a drill to turn the spool holder; (2) allows for smooth deployment of material via a slip sleeve that spins on the handle and shoulder; and (3) the exposed solid portion of the handle can also operate as manual re-spooling mechanism with improved efficiency.

[0045] Similarly, the associated method is unique in that it: (1) allows for a simple method to secure a disposable spool onto a simple friction inducing structure; (2) allows for hooks for hanging the device and secure the spoolable material for storage and during use. Similarly, the disclosed method is unique when compared with other known processes and solutions in that the simple design and structure will save on manufacturing cost so that the device may be offered at a low price.

[0046] As it relates to the split device spool option, the handle and outside shoulder are two separate components. They are both pressed into and held in place with spring tensioners. An axle joins the two parts within the disposable spool. The joining takes place as the outside shoulder axle fits tightly within the handle and handle spool as they have similar and complementary shapes. The drawings show a hexagonal shape example; however, many shapes would be functionable. The drawings show where the axle is guided into the hex receiver via a funnel shaped receive cone. By joining the two parts together the device grip on the disposable spool core is shared between the two parts. This increases the device's ability to maintain stable grip within the disposable core when torque is applied. The outside shoulder may have a knob. The handle, inside shoulder, and device spool may all be connected via a dowel.

[0047] As it relates to the hex bit locking shoulder, there are two parts to this device configuration. The shoulder and the device spool with handle. The outside shoulder is assembled with a locking mechanism, at the core, as a single part, referred to as the outside shoulder. This shoulder securely locks into device spool via the hourglass locking segment. To secure the two parts together the locking segment is inserted within the locking mechanism to form a secure bond. When connected together the two parts can only be separated by manually bulling back on the plunger. This is done with two fingers pulling on the outer lip flare while pushing back on the shoulder hex segment and away from the device spool. The two parts are locked together when the hex bit locking mechanism marries with the hourglass hex locking segment. When assembled the hex bit locking mechanism is a shoulder and operates as one unit.

[0048] Also, in this configuration the end of the spool handle is used for manual spooling. As it relates to the magnet secured shoulder. The magnetic outside shoulder is married to the spool device for operation utilizing the attraction capability of a magnet. In one possible configuration the magnet is placed within the device spool at the end of a hex receiver sleeve. The shoulder has a hex bit that slides into the hex receiver sleeve within the spool device. The end of the shoulder hex bit marries to the magnet placed at the end of the hex receiver sleeve. This marriage attractions holds the shoulder to the device spool for use. The end of the outside end of the shoulder has a hex bit receiver and thumb turn manual winder. When the manual winder is spun by the operator line can be spooled onto the device. The end of the handle (handle cap may also be used as a winder in the same manner. The shoulder hex receiver sleeve in this configuration is used to transfer torque from a power tool to the device.

[0049] A string lock securing notch can be built into one or both shoulders (and spool holder). The string securing notch has a funnel opening that leads to a pinch point. This pinch point may then open into a second funnel that tapers to a point. This area is designed to allow for easy placement of the loose string and secure it in place for storage. It can help the string on the spool. Thereby holding the string in place and avoiding the string from unintentionally unraveling off the spool.

[0050] Additional methods of joining the device spool to the shoulder not shown. One such method is to use a system similar to a common method of holding a socket to a ratchet tool. This method uses a compressed spring and round barring mechanism on a shaft. When the shaft is inserted into the socket sleeve receiver, the barring is forced into a divot. The marriage of the round barring and the divot form a solid connection.

[0051] The disclosed device is unique in that it is structurally different from other known devices or solutions. More specifically, the device includes a torque transfer connection centered and rotationally balanced for spooling material using the power from readily available handheld electric tool. The torque transfer end of the device can be configured with both an internal and external connections. The industry standard disposable spools are held in place with a compression and friction. The rectangle dimensions of one spool design creates a tight fit within a disposable spool.

[0052] At an end of the spool holder, two hooks can be provided and configured to allow the material to wrap, lock into place, and hang the tool during use. The hooks can be wide at the outside and angled to keep the spooled material from sliding off when suspended from the deployed material in the work area. The slotted hooks are also designed for a means to lock the material in place during storage. The hooks have an inner section that allows material to enter and stay in place.

[0053] The handle and slip sleeve are configured to allow the smooth deployment of the material. It does this while maintaining a dedicated section of the handle outside the sleeve for manual retraction. The device handle can further include a trench in which an angled lip of the slip sleeve rides. The joining of a slip sleeve lip, riding within the trench of the handle, secures the slip sleeve up against the backside of the spool shoulder.

[0054] The solid handle can be configured to be longer than the slip sleeve. This increased length allows the operator to spin the spool with their fingers. Thereby, allowing for manual retraction on a handle outfitted with a slip sleeve. The slip sleeve is also designed with a curve at the transition from the handle to the shoulder.

[0055] Furthermore, the process associated with the aforementioned device is likewise unique. When configured as an internal hex receiver, the torque transfer end will accept a standard hex bit. The industry standard hex bit is structured to connect with the chuck of a handheld drill type tool. When engaged, the drill type tool is thereby able to apply torque to the spooling device. The curved transition of the slip sleeve can be ergonomically designed to fit comfortably in the hand and slide smoothly over the handle and shoulder. The device spool holds the disposable spool in place by either forcing the round cardboard inner core of the disposable spool somewhat out of round or by compressing spring wire tensioners. The force of the compressed disposable spool core onto the device spool maintains enough friction to hold the disposable spool in place in a simple cost-effective way. Utilizing spring tensioners to hold the disposable spool in place has the advantage of accommodating variation in disposable spool core sizes. The hooks on the device spool secure the device for storage so that the material will not unintentionally unwind off the spool.

[0056] The material can be wrapped around the hooks to conveniently hang the device where it can be easily accessed during use. Without the hooks, the tool might otherwise need to be laid down, away from the workspace. When this happens, excess energy is needed to retrieve the device and un-utilized material is deployed, possibly causing a trip hazard. When excess material is deployed it needs to be rewound onto the spool. Thereby, wasting what would otherwise be productive time. The hooks allow the operator to hang the device in an ergonomically accessible location. The device may also be used as a plum weight while suspended from the spoolable material.

[0057] The present disclosure provides for a hex bit locking shoulder having a shoulder and the device spool with handle. The outside shoulder is assembled with a locking mechanism, at the core, as a single part, referred to as the outside shoulder. This shoulder securely locks into device spool via the hourglass locking segment. To secure the two parts together the locking segment is inserted within the locking mechanism to form a secure bond. When connected together the two parts can only be separated by manually bulling back on the plunger. This is done with two fingers pulling on the outer lip flare while pushing back on the shoulder hex segment and away from the device spool. The two parts are locked together when the hex bit locking mechanism marries with the hourglass hex locking segment. When assembled the hex bit locking mechanism is a shoulder and operates as one unit. Also, in this configuration the end of the spool handle is used for manual spooling.

[0058] The present disclosure provides for a magnet secured outside shoulder is married to the spool device for operation utilizing the attraction capability of a magnet. In one example configuration, the magnet is placed within the device spool at the end of a hex receiver sleeve. The shoulder can include a hex bit that slides into the hex receiver sleeve within the spool device. The end of the shoulder hex bit marries to the magnet placed at the end of the hex receiver sleeve. This marriage attractions holds the shoulder to the device spool for use. The end of the outside end of the shoulder has a hex bit receiver and thumb turn manual winder. When the manual winder is spun by the operator line can be spooled onto the device. An end of the handle (i.e., handle cap) may also be used as a winder in the same manner. The shoulder hex receiver sleeve in this configuration can be used to transfer torque from a power tool to the device.

[0059] In an example, the device includes the following components: a spool, a torque transfer connection centered on the end of the spooler, a handle, a slip sleeve, securing hooks, a removable hex bit and a removable round bit. These components can be connected as follows: the handle, securing hooks, shoulder and spool are connected as one solid unit. The device spool is designed to utilize friction to secure a disposable spool. It does this by spreading the core of the disposable spool out of round. This friction holds the disposable spool in position on the spool and against the shoulder. The slip sleeve is secured in place so that it rotates around a portion of the handle and up against most of the shoulder. The slip sleeve is curved at the transition from the handle to the shoulder. This is done to ergonomically fit comfortably in the hand and slide smoothly over the device handle and shoulder. The power torque transfer connection is integrated as an internal hex bit receiver and removable exterior hex bit. It should further be noted that, the slip sleeve may be secured to allow rotation and stability with a variety of configurations. The manor chosen for illustration in this document utilizes a handle trench and slip sleeve lip design. The design importance of the slip sleeve connection is that it allows the slip sleeve smoothly rotates over the handle and shoulder while maintaining a dedicated space on the handle for manual retraction and deployment.

[0060] A method associated with the present disclosure includes the following steps: deploying the spoolable material (hereafter may be referred to as string) by securing the working end of the string with a second person or a non-moveable object; holding the handle at the slip sleeve near the raised shoulder and moving the tool away from the secured section of string holding just the slip sleeve section of the handle, and optionally holding the rounded exterior portion of a hex bit inserted into the hex receiver for a two hand deployment operation.

[0061] The following three methods for retracting the string after detaching the secured end are disclosed below are provided by way of example and not meant to over limit the subject matter of the present disclosure.

[0062] A first example method includes securing a standard hex bit into the chuck of a power drill. The drill is then set to clutch to the lowest setting. The hex bit is then inserted into the spooling tool hex receiver. Torque is slowly applied from the power drill to spin the spool. The string will wind onto the spool.

[0063] In a second example method, the removable torque transfer bit is inserted into the hex receiver. A power drill or impact driver is connected onto the removable torque transfer bit. The drill clutch is then set to the lowest setting. The power tool slowly provides torque to spin the spool. The string will wind onto the spool.

[0064] In a third example method, the spool is held with the non-dominant hand, palm up so the fingers guide the string onto spool. The rigid end of the handle can be grasped with a dominant hand. The rigid portion of the handle is spun with fingers of the dominant hand. This will spin the spool and retract the string. It should further be noted that the spooler tool can be constructed of numerous materials including but not limited to metal, plastic, vinyl, elastomeric or similar.

[0065] Referring to FIG. 1 and FIG. 2, exploded views of the device utilizing a split spool holder axle with the interior exterior hex bit receiver connection are provided. The spooling device includes a spool holder axle 1a and 1b. This is the area upon which the disposable string line roll core (see FIG. 7 and FIG. 8) slides onto and is held in place with tension springs. The spool holder axle is the location where torque is transferred from the device to the disposable string line that rolls during spooling operations.

[0066] Spool shoulders 2a and 2b are placed outside of the disposable string line core (not a part of this device, see FIG. 8 and FIG. 9). The two spool shoulders help to contain the string from exiting the defined spooling area. Spool shoulders 2a and 2b may have cleat traps 2c on the shoulder to secure string line when not in use. The cleat trap 2c has a rounded entrance where the string enters curved for safe spooling, in anticipation that an operator may choose to use an ungloved hand to guide the string onto the spool. In this event the operator's hand would be in close proximity to both shoulders as they are spinning. The use of a rounded entrance on the cleat trap 2c is a feature to protect the operator's hand should it come in contact with one of the shoulders 2a or 2b at 2c. The rounded entrance to the cleat trap 2c also channels the string into the cleat trap 2c where a fishhook type barb is integrated into the cleat for the purpose of holding the string in place for storage or hanging the tool off the ground.

[0067] Spool handle 3 is connected with the spool shoulder and axle(s) so as to spin in unison. In this example, spool holder axle 1a is shown in an exploded view separated from the shoulder 2a and handle 3. Note that axle 1a, shoulder 2a, handle 3, and handle end cap 5 can be integrated or rigidly connected during manufacturing or during assembly.

[0068] The device further includes a handle slip sleeve 4 configured to slide over the spool handle 3. Handle slip sleeve 4 is held in the operator's hand during string deployment. During string deployment (the unspooling of string) all of the part spin as string is unwound from the spool. While all of the parts including spool holder axle 1a, shoulder 2a, and handle 3, all spin during deployment. Handle slip sleeve 4 remains stationary. This is because the slip sleeve and handle have a small space between these two parts. The purpose of the slip sleeve is to eliminate friction between the device and the operator's hand.

[0069] In an example, a handle end cap 5 is connected to spool handle 3. It is used to secure the slip sleeve spool from sliding off the spool handle 3. When the end cap 5 is secured with a solid connection to the spool handle, it can be used to wind string onto the spool manually with the fingers.

[0070] Internal torque transfer connection 6 provides for an area that is sized to receive standard size hex bits. This is the area where power is transferred to the device from a power drill or impact driver.

[0071] In an example, the present disclosure provides for one or more magnets 7 at a proximal end of the internal torque transfer connection 6. The magnet(s) helps keep the hex bit within the device during operation.

[0072] A manual retraction knob 8 can be provided for short spooling and or when a power tool, like a drill or impact driver, is unavailable. This protrusion is spun with a quick flick of the thumb and fingers.

[0073] In another example, split spool sliding axle 9 is hex shaped and connected to the spool holding axle 1b and slides in and out of the split spool axial receiver 10. Split spool axle receiver 10 can be hexagonal shaped and allow the split spool sliding axle to slide in and out of its hexagonal casing. The purpose of this is to allow for a variety of disposable spool sizes 20.

[0074] FIG. 3 provides an exploded top oblique view of a device utilizing a single axle with the handle. Spool holder axle 11 is provided for disposable string line roll core 20. It slides onto and is held in place with tension springs 11a. At an end of the spool holder axle is a spool shoulder stop 11b. The spool shoulder 12a locks into the spool shoulder stop 11b thereby the confining the disposable spool 20 into its proper location on the spool. The spool holder axle 11 is the location where torque from a power tool is transferred from the device to the Disposable String Line core 20 during spooling operations.

[0075] Spool shoulder 12a slides over the to the end of spool holder axle 11 until it is seated at spool shoulder stop 11b. After which the disposable string line spool 20 is loaded onto the spool holder axle 11. Spool shoulder 12b is then slid over spool handle 13 and seated against the disposable string line spool 20.

[0076] Spool handle 13 is connected with the spool holder axle 11 and so as to spin in unison. The spool handle can include a receiver clip 13b.

[0077] Handle slip sleeve 14 is configured to slide over the spool handle 13. This part is held by the operator during string deployment. While the holding axle 11, shoulder 12a and 12b, and spool handle 13 all spin during deployment. The handle slip sleeve 14 remains stationary in the operator's hand. This is because the handle slip sleeve 14 and spool handle 13 have close but not connected surfaces. The purpose of the slip sleeve 14 is to eliminate friction between the device and the operator's hand.

[0078] End cap clip 15 can be connected to spool handle 13 during assembly. The end cap clip purpose is to hold the handle slip sleeve 14 in place on the spool handle 13. The end cap clip 15 has a button end that has a wider diameter than the handle slip sleeve 14. This extra width does not allow the handle slip sleeve 14 to become dislodged from the rest of the device. The handle end cap has two separated end cap clips 15a. When assembled the end cap clip 15a fits into the receiver clip 13a. These clips are held together by spring action build into both parts. When the clips slid together the cap clips compress together to marry into the receiver clip 13a. While the end cap clip 15 are compressing the receiver clips 13a arms are deformed outward until the end cap clip is fully inserted into the receiver clip 13a. After full insertion the spring action of both parts decompress and hold the two pieces together.

[0079] In an example, external torque transfer connection 16 is a hexagonal rod that connects to the spool holder axle 11. This is a specialized part that is made to fit into standard hex bit receivers and locking hex bit receivers (standard on impact drivers). The torque transfer connection 16 has a half round shank with an hourglass curve. While this end is standard on drill bits and Phillips-end screwdriver bits it is not known to be used with a prior string winding device. The shank is approximately a as is standard. This is the area where power is transferred to the device from a power drill or impact driver.

[0080] FIG. 4 shows an exploded top oblique view of a device utilizing a single axle with the exterior hex bit connection in the foreground.

[0081] Spool holder axle 11 provides for an area upon which the disposable string line roll core 20 slides onto and is held in place with tension springs 11a. At the end of the spool holder axle is a spool shoulder Stop 11b. The spool shoulder 12a locks into the spool shoulder Stop 11b thereby the confining the spool shoulder 20 into its proper location on the spool. The spool holder axle 11 is the location where torque from a power tool is transferred from the device to the disposable string line core 20 during spooling operations.

[0082] Spool shoulder 12a and 12b: are configured to slide over the to the end of spool holder axle 11 until it is seated at spool shoulder stop 11b. After which the disposable string line spool 20 is loaded onto the spool holder axle 11. Spool shoulder 12b is then slid over spool handle 13 and seated against the disposable string line spool 20.

[0083] The spool handle 13 can be rigidly connected with the spool holder axle 11 and so as to spin in unison. The Spool handle has a receiver clip 13b.

[0084] Handle slip sleeve 14 is configured to slide over the spool handle 13. This part is held by the operator during string deployment. While the holding axle 11, shoulder 12a and 12b, and spool handle 13 all spin during deployment. The handle slip sleeve 14 remains stationary in the operator's hand. This is because the handle slip sleeve 14 and spool handle 13 have close but not connected surfaces. The purpose of the slip sleeve 14 is to eliminate friction between the device and the operator's hand.

[0085] End cap clip 15 is connected to the spool handle 13 during assembly. The purpose is to hold the handle slip sleeve 14 in place on the spool handle 13. The end cap clip 15 has a button end that has a wider diameter than the handle Slip sleeve 14. This extra width does not allow the handle slip sleeve 14 to become dislodged from the rest of the device. The handle end cap has two separated end cap clips 15a. When assembled the end cap clip 15a fits into the receiver clip 13a. These clips are held together by spring action build into both parts. When the clips slid together the cap clips compress together to marry into the receiver clip 13a. While the end cap clip 15 are compressing the receiver clips 13a arms are deformed outward until the end cap clip is fully inserted into the receiver clip 13a. After full insertion the spring action of both parts decompress and hold the two pieces together.

[0086] External torque transfer connection 16 can be configured as a hexagonal rod that connects to the spool holder axle 11. This is a specialized part that is made to fit into standard hex bit receivers and locking hex bit receivers (standard on impact drivers). The torque transfer connection 16 has a half round shank with an hourglass curve. While this end is standard on drill bits and Phillips ended screwdriver bits it is not known to be used with a prior string winding device. The shank is approximately a as is standard. This is the area where power is transferred to the device from a power drill or impact driver.

[0087] FIG. 5 shows just the single axle body with the interior hex bit receiver connection. Spool holder axle 11 is an area upon which the disposable string line roll core 20 slides onto and is held in place with tension springs 11a. At the end of the spool holder axle is a spool shoulder stop 11b. The spool shoulder 12a locks into the spool shoulder stop 11b thereby the confining the disposable spool 20 into its proper location on the spool. The spool holder axle 11 is the location where torque from a power tool is transferred from the device to the disposable string line core 20 during spooling operations.

[0088] The spool handle can be rigidly connected with the spool holder axle 11 and so as to spin in unison. The spool handle has a receiver clip 13b. Receiver clip 13 holds the internal torque transfer connection 17. This is an area that is sized to receive standard size hex bits. This is the area where power is transferred to the device from a power drill or impact driver. Hanging hooks 19 are provided at the base of the spool holder axle 11. These hooks can be used to create friction for hanging the device off the ground during use. To use the hanging hooks the string is wound around the area between.

[0089] FIG. 6 shows the outside split axel shoulder with a close up look at the cleat trap 2c and manual spooling knob 8. Spool shoulders 2b are placed to the outside of the disposable string line core. The two spool shoulders help to contain the string from exiting the defined spooling area. Spool shoulders 2b may have cleat traps 2c on the shoulder to secure string line when not in use. The cleat trap 2c has a rounded entrance where the string enters curved for safe spooling. In anticipation that an operator may choose to use an ungloved hand to guide the string onto the spool. In this event the operator's hand would be in close proximity to both shoulders as they are spinning. The use of a rounded entrance on the cleat trap 2c is a feature to protect the operator's hand should it come in contact with one of the shoulders 2a or 2b at 2c. The rounded entrance to the cleat trap 2c also channels the string into the cleat trap 2c where a fishhook type barb is integrated into the cleat for the purpose of holding the string in place for storage or hanging the tool off the ground. Manual retraction knob 8 is used for short spooling and or when there isn't a power too like a drill or impact driver available. This protrusion is spun with a quick flick of the thumb and fingers.

[0090] FIG. 7 shows a device utilizing a single axle assembled and loaded with a disposable spool of string with the handle. Spool shoulders 2a and 2b are placed to the outside of the disposable string line core. The two spool shoulders help to contain the string from exiting the defined spooling area. Spool shoulders 2b may have cleat traps 2c on the shoulder to secure string line when not in use. The cleat trap 2c has a rounded entrance where the string enters curved for safe spooling. In anticipation that an operator may choose to use an ungloved hand to guide the string onto the spool.

The string is unspooled for use then respooled for storage or reuse in another area.

[0094] FIG. 9 shows an assembled side view of the device utilizing a split spool holder axle with disposable string line spool 20. The device is assembled in two parts. The handle 3, slip sleeve 4, end cap 5, spool holder axle 1a, and split spool axle receiver 10 are assembled as a single unit. Internal torque transfer connection 6, magnet 7, manual retraction knob 8, spool shoulder 2b, spool holder axle 1b, and split spool sliding axle 9 are assembled as another single unit.

[0095] The manual retraction knob 8 is configured to serve two functions: to be used for manual spooling by assisting with finger gripping on a scalloped side. Adding gripping assistance on retraction knob 8 assists with manual spooling since fingers are used for spinning during manual respooling. The second benefit of retraction knob 8 is a structure holding the internal torque transfer connection 6, which provides a connection point for power spooling. Shoulder 2b maintains and confines an area in which the string line is spooled onto the spool holder axle 1a and 1b.

[0096] To load the device with disposable string line roll 20, the two halves of the device are slid together by joining split spool sliding axle 9 and split spool axle receiver 10. In this example, split spool sliding axle 9 slides into split spool axle receiver 10. The two halves are configured to join together with a disposable string line roll 20 core centered on the split spool sliding axle 9.

[0097] FIG. 1 illustrates tabs 1c that provide spring action when compressed. Disposable string line roll 20 is held by the spool holder axle 1a and 1b (see FIG. 1) via friction established by spring action of tabs 1c (See FIG. 1). Split spool sliding axle 9 is inserted into the split spool axle receiver 10 (see FIG. 9). Power can be transmitted from internal torque transfer connection 6 to split spool sliding axle 9 and into split spool axle receiver 10.

[0098] FIG. 9 illustrates a hexagonal shape example of split spool sliding axle 9 and split spool axle receiver 10, however many shapes would be functionable and within the scope of this disclosure. The drawings show where the axle is guided into the hex receiver via a funnel-shaped receiver cone. By joining the two parts together the device grip on the disposable spool core is shared between the two parts. This increases the device's ability to maintain stable grip within the disposable core when torque is applied.
