RELATED APPLICATION

[0001] This application claims the full Paris Convention benefit of and priority to U.S. Provisional Patent Application Serial No. 61/486,727 filed May 16, 2011, the contents of which are incorporated by reference in their entirety, as if fully set forth herein.

BACKGROUND

1. Field

[0002] This disclosure relates to a flexible connection device and system.

2. General Background

[0003] Handles with removable tools are known in the art. Friction fits, pressure fits and spring loaded mounts are traditionally used.

[0004] A socket wrench is a type of wrench that uses separate, removable sockets to fit different sizes of nuts and bolts. A socket wrench is a wrench with interchangeable heads called sockets that attach to a fitting on the wrench, allowing it to turn different sized bolts and other fasteners. The most common form is a hand tool popularly called a ratchet, consisting of a handle with a ratcheting mechanism built in, so it can be turned using a back-and-forth motion in cramped spaces. A socket is a cup-shaped fitting with a recess that grips the head of a bolt. The socket snaps onto a male fitting on the handle. The handle supplies the mechanical advantage to provide the torque to turn the socket. The wrench usually comes in a socket set with many sockets to fit the heads of different- sized bolts and other fasteners. The advantage of a socket wrench is that, instead of a separate wrench for each of the many different bolt heads used in modern machinery, only a separate socket is needed, saving space.

SUMMARY

[0005] The disclosure teaches a flexible connector or living hinge for use in mounting tools to a larger element such as a handpiece, shaft or the like. Generally, a tool collar with a closed back end and an open front having an outer annular wall provides an open end shaped into a tool socket. Said tool socket also having an annular wall. A bearing guide is fluidly connected between both annular walls and a bearing may be fitted within said guide. To limit said bearing from falling through said bearing guide, the end of the bearing guide adjacent to the tool shaft is of a smaller diameter than the bearing therein. To prohibit loss of the bearing and/or to dynamically move said bearing within said bearing guide, a sleeve with a flexible hinge (or living hinge) is snuggle placed or affixed over said tool collar. In some instances an alignment guide may be formed with the tool socket to limit orientation of any insertable tool therein. In some a shaft may be affixed to the closed back end of the tool collar whereby said tool collar may be affixed to one of a handle, a larger device and a power tool.

[0006] The disclosure teaches a flexible connector or living hinge for use in mounting tools to a larger element such as a handpiece, shaft or the like. Generally, a tool collar with a closed back end having a shaft formed as part of, or affixed thereto. Said tool collar has and an open front having an outer annular wall provides an open end shaped into a tool socket. Said tool socket also having an annular wall. A bearing guide is fluidly connected between both annular walls and a bearing may be fitted within said guide. To limit said bearing from falling through said bearing guide, the end of the bearing guide adjacent to the tool shaft is of a smaller diameter than the bearing therein. To prohibit loss of the bearing and/or to dynamically move said bearing within said bearing guide, a sleeve with a flexible hinge (or living hinge) is snuggle placed or affixed over said tool collar the shaft is affixed to one of a handle device and a power tool. In some instances, a tool is fitted into said tool socket. The tool provides a latch for said bearing. In such instances the bearing forms a catch. The latch may be an annular bearing guide such as a concave channel. The annular bearing guide may also be a cut out, divot, well, or the like and not circumnavigate the tool. In some instances, multiple flexible hinges formed in said sleeve and multiple bearings which fit into multiple annular bearing guides. In some instances of multiple bearings, the bearing guides of the tool collar are positioned generally aligned. In other instances, said bearing guides are disaligned. Said sleeve may be formed of at least one of plastics, resins, metals, composites, rubbers, and polymers.

[0007] The disclosure teaches a method of reversibly attaching tools wherein a tool collar with an open ended tool socket having a movable bearing within a guide is in fluid connection with the outer and inner walls of said tool collar. A sleeve material is fitted over said tool collar. The sleeve has at least a flexible region (also called a living hinge) which is seated above said bearing in said guide. The flexible region of said sleeve above said bearing is displaceable by the pressure exerted thereon from the bearing moving against it as the bearing is displaced during insertion of a tool within said tool shaft. When an annular bearing guide formed in said tool aligns with said bearing, the flexible hinge urges the bearing into the annular bearing guide, thereby cooperating in a latch and catch arrangement to hold the tool in the tool shaft.

[0008] The disclosure teaches a method of reversibly attaching tools wherein a tool collar with an open ended tool socket having a movable bearing within a guide is in fluid connection with the outer and inner walls of said tool collar. A sleeve material is fitted over said tool collar. The sleeve has a partially closed back end which forms an asymmetrical latch which mates with a corresponding catch at the back of said tool collar. The sleeve has at least a flexible region (also called a living hinge) which is seated above said bearing in said guide. The flexible region of said sleeve above said bearing is displaceable by the pressure exerted thereon from the bearing moving against it as the bearing is displaced during insertion of a tool within said tool shaft. When an annular bearing guide formed in said tool aligns with said bearing, the flexible hinge moves up and down and acts to urges the bearing into the annular bearing guide, thereby cooperating in a latch and catch arrangement to hold the tool in the tool shaft.

[0023] According to some aspects of exemplary implementations, as shown in Figures 1 and 2 and 3 there is a tool mount with flexible connector 5. A tool collar 10 with a closed back end, and open front end, an outer annular wall 11 with an open ended tool socket 12 having an inner annular wall and a bearing guide 14 is shown affixed to a shaft 20. A sleeve 30 with flexible "U" hinge 32 is sized to snuggly slide over the tool collar 10 and bearing guide 14. A bearing 40 fits in the bearing guide. The bearing guide 14 is an open channel with a fluid connection from the outer annular wall 11 of the tool collar 10 to the annular wall 13 of the tool socket. The edge of the bearing guide 14 also being adjacent to (and in fluid connection with) the annular wall 13 of the tool socket (which may be generally referred to as the inner wall of the tool collar) is of a diameter smaller than the diameter of the bearing 40. The edge of the bearing guide 14 adjacent to the outer annular wall 11 of the tool collar is of a diameter large enough for said bearing to move up and down within the bearing guide 14. Those of ordinary skill in the art will recognize that a tool socket may be conformed to fit a specific tool mount, geometric, radiuses, partially radiused and the like.

[0024] Figures 4 and 5 illustrate some aspects of an exemplary implementation of a hand tool with flexible connection hinge 80. The tool collar 10 with tool socket 12 includes an alignment guide 34 which is raised within the tool socket 12. A bearing 40 in a bearing guide is movably affixed within the bearing guide and positioned beneath a flexible "C" shaped hinge 35. The shaft 20 affixed within a handle 50 combines a tool mount with flexible connector and handle 50 forming a tool 80 (in this instances hand held) with flexible connector. Those of ordinary skill in the art will recognize that the subject matter of this disclosure is not limited to hand tools and that said shaft 20 could be designed to fit within in a collar of a powered tool and the like. Powered tools and devices include drills and other rotating devices.

[0025] A tool 100 with a shaped proximal end 101 and a annular bearing guide 102 fits within said tool socket. Said bearing is of a size and shape whereby it is displaced upward from the tool socket towards the outer wall of the tool collar constrained within said bearing guide by said flexible hinge 35. Said flexible hinge being formed of an elastomeric material with memory. Materials may include, but are not limited to plastics, resins, metals, composites, rubbers and polymers. Said flexible hinge may be displaced by the force of a moving bearing. Said bearing fitting within said annular bearing guide when said flexible hinge urges said bearing therein. At the distal end 103 of the tool 100 is formed to, in some instances, provide a tool catch 104. Said tool catch may affix tools such as fastening tools, cutting tools, positioning tools and the like. The alignment guide 34 may be used to orient a tool 100 with an alignment portion 105 in the correct position. Those of ordinary skill in the art will recognize that said tool catch may be eliminated and a tool may be formed at the distal end of the tool shaft. Those of ordinary skill in the art will also recognize that such an arrangement to affix a tool shaft which may have a variety of tool catches provides a single handle which may be used with a multitude of tool platforms.

[0026] Figures 6 and 7 illustrate some aspects of an exemplary implementation of a hand tool or hand device with flexible connection hinge 200. A bearing 40 in bearing guide is movably affixed within the bearing guide and positioned beneath a flexible "C" shaped hinge 35. The shaft 20 affixed within a handle 50 combines a tool mount with flexible connector and handle 50 forming a tool 200 (in this instances hand held) with flexible connector which fits snuggly over a tool collar 201 having a tool socket 202. A sleeve 30 with flexible "U" hinge 35 is sized to snuggly slide over the tool collar 201 and bearing and bearing guide. The sleeve 30 is generally cylindrical with a partially closed back end 31 and an open front end.

[0027] A tool 110 with a shaped proximal end 111 and a annular bearing guide 112 reversibly mountable to fit within a tool socket 202. At the distal end 113 of the tool 110 is formed to , in some instances, provide a tool catch 1 14. Said tool catch may affix tools such as fastening tools, cutting tools, positioning tools and the like. Those of ordinary skill in the art will recognize that said tool catch may be eliminated and a tool may be formed at the distal end of the tool shaft. Those of ordinary skill in the art will also recognize that such an arrangement to affix a tool shaft which may have a variety of tool catches provides a single handle which may be used with a multitude of tool platforms.

[0028] Figures 8 and 9 illustrate some aspects of an exemplary implementation of a hand tool or hand device with flexible connection hinge 300. The tool collar 301 with bearing guide 302 and tool socket 303. A bearing 304 in bearing guide is movably affixed within a bearing guide 302 and positioned beneath a flexible hinge 306 formed in a collar sleeve fitted over the tool collar. A back shaft 325 affixed to the tool collar extends opposite the tool socket 202 and may be used to connect the tool with flexible connection hinge 300 to a handle, chuck, tool, power tool and the like. When the front shaft 330 is urged forward within the tool socket 303 the bearing 304 within the bearing guide 302 moves away from the tool socket thereby pushing on the flexible hinge 306 thereby elastically deforming it along the line of arrow 1000 in the bearing guide 332 as front shaft 330 is removed from the tool socket 303.

[0029] Figures 10 and 11 illustrate some aspects of an exemplary implementation of a tool with flexible connection hinge 400. The tool collar 401 with a first bearing guide 402 and a second bearing guide 402' and tool socket 403. A first bearing 404 is placed in the first bearing guide 402 an a second bearing 404' resides in the second bearing guide 402' , each bearing being movably affixed. Both bearings are generally on the same side of the tool collar. Over the first bearing 402 is placed a first flexible hinge 406 and over the second bearing is a second flexible hinge 406' formed in a collar sleeve 407 fitted over the tool collar. A back shaft 325 affixed to the tool collar extends opposite the tool socket 403 and may be used to connect the tool with flexible connection hinge 400 to a handle, chuck, tool, power tool and the like. When the front shaft 430 is urged forward within the tool socket 403 the bearing within the bearing guides moves away from the tool socket thereby pushing on the flexible hinges thereby elastically deforming it along the line of arrows 1001 and 1002 in the bearing guides as front shaft 430 is removed from the tool socket 403.

[0030] Figures 12 illustrate some aspects of an exemplary implementation of a hand tool or hand device with flexible connection hinge 500. The tool collar 501 with a first bearing guide 502 and a second bearing guide 502' and tool socket 503. A first bearing 504 is placed in the first bearing guide 502 and a second bearing 504 resides in the second bearing guide 504, each bearing being movably affixed. Both bearings are dis-aligned on the tool collar. Over the first bearing 502 is placed a first flexible hinge 506 and over the second bearing 504 is a second flexible hinge 506, formed in a collar sleeve 507 fitted over the tool collar. A back shaft 325 affixed to the tool collar extends opposite the tool socket 503 and may be used to connect the tool with flexible connection hinge 500 to a handle, chuck, tool, power tool and the like. If the front shaft 530 is urged forward within the tool socket 503 the bearing within the bearing guides 525 will move away from the tool socket pushing on the flexible hinges and will thereby elastically deform it along the line of arrows 1003 and 1004 as front shaft 530 is removed from the tool socket 503.

[0031] Figure 13 shows a top view of a flexible hinge 600. A sleeve 30 has a circular ball alignment 601 formed therein. A plurality of channels 602 extend from said ball alignment. A ball bearing 40 is held beneath said ball alignment in a bearing guide (not shown). The ball alignment 601 has a diameter smaller than that of said ball bearing. Flexible flaps 604 are formed between each pair of channels. Said flaps have multiple free edges at the ball alignment, and at the channels. The portion of the flap attached to the larger sleeve (between said channels) forms a natural hinge, and when said ball bearing pushes upward at the ball alignment said flap yields and is displaced to allow movement. By utilizing material with memory, the flaps will urge the ball bearing back into the bearing guide and to mate with any catch or latch on a tool that said bearing may temporarily affix.

[0032] According to some aspects of exemplary implementations, as shown in Figures 14 and 15 there is a tool mount with flexible connector. A tool collar 10 with a closed back end 15 and open front end forming tool socket 12 having an inner annular wall and a bearing guide 14 is shown affixed to a portion of a shaft 20. For illustration purposes shaft 20 is not fully shown. A sleeve 30 with flexible "U" hinge 35 is sized to snuggly slide over the tool collar 10 and bearing guide 14. A bearing 40 fits in the bearing guide. The bearing guide 14 is an open channel with a fluid connection from the outer annular wall of the tool collar 10 to the annular wall of the tool socket. The interface of the shaft with the back end 15 of the tool collar 10 has a positioning catch 21 which is an asymmetrical extension from the back of the tool collar and/or around the shaft.

[0033] A sleeve 30 with flexible "U" shaped hinge 35 is sized to snuggly slide over the tool collar 10 and bearing guide. The sleeve 30 is generally cylindrical with a partially closed back end 31 and an open front end. Formed through the partially closed back end 31 is an assymetrical latch 32 which receives the positioning catch 21. The latch and catch are utilized to position the hinge 35 in a preselected orientation to the bearing 40. Those of ordinary skill in the art will recognize that said positioning latch catch may be chosen from a plethorea of shapes which all would be within the present disclosure. [0034] While the method and apparatus have been described in terms of what are presently considered to be the most practical and preferred implementations, it is to be understood that the disclosure need not be limited to the disclosed implementations. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structures. The present disclosure includes any and all implementations of the following claims.

[0035] It should also be understood that a variety of changes may be made without departing from the essence of the disclosure. Such changes are also implicitly included in the description. They still fall within the scope of this disclosure. It should be understood that this disclosure is intended to yield a patent covering numerous aspects of the disclosure both independently and as an overall system and in both method and apparatus modes.

[0036] Further, each of the various elements of the disclosure and claims may also be achieved in a variety of manners. This disclosure should be understood to encompass each such variation, be it a variation of an implementation of any apparatus implementation, a method or process implementation, or even merely a variation of any element of these.

[0037] Particularly, it should be understood that as the disclosure relates to elements of the disclosure, the words for each element may be expressed by equivalent apparatus terms or method terms - even if only the function or result is the same.

[0038] Such equivalent, broader, or even more generic terms should be considered to be encompassed in the description of each element or action. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this disclosure is entitled.

[0039] It should be understood that all actions may be expressed as a means for taking that action or as an element which causes that action.

[0040] Similarly, each physical element disclosed should be understood to encompass a disclosure of the action which that physical element facilitates. [0041] Any patents, publications, or other references mentioned in this application for patent are hereby incorporated by reference. In addition, as to each term used it should be understood that unless its utilization in this application is inconsistent with such interpretation, common dictionary definitions should be understood as incorporated for each term and all definitions, alternative terms, and synonyms such as contained in at least one of a standard technical dictionary recognized by artisans and the Random House Webster's Unabridged Dictionary, latest edition are hereby incorporated by reference.

[0042] Finally, all referenced listed in the Information Disclosure Statement or other information statement filed with the application are hereby appended and hereby incorporated by reference; however, as to each of the above, to the extent that such information or statements incorporated by reference might be considered inconsistent with the patenting of this/these disclosure(s), such statements are expressly not to be considered as made by the applicant(s).

[0043] In this regard it should be understood that for practical reasons and so as to avoid adding potentially hundreds of claims, the applicant has presented claims with initial dependencies only.
