Smith Attorney, Agent, or Firm-Sellers and Brace [57] ABSTRACT A keeper accessory for use on 12-point socket wrenches to hold a hex fastener captive without need for retainers or modification of a conventional wrench. The accessory is selectively usable with cylinder and box type wrenches and comprises at least one end ringlet preferably supporting two or more parallel legs shaped to lie along a respective point of a wrench with its radially opposed surfaces disposed to frictionally engage a hex face of a fastener and the juxtaposed point areas of the wrench thereby to grip and hold the fastener captive.
9 Claims, 5 Drawing Figures KEEPER FOR SOCKET WRENCHES This invention relates to accessories for wrenches, and more particularly to an improved keeper accessory formed in one piece from non-metallic material and selectively installable in either a box or cylinder type socket wrench with portions thereof gripping the one or more faces of a hex fastener part.
This application is related to my copending application for U5. Letters Pat. Ser. No. 187,684, filed Oct. 8, 1971, but embodies certain structural and functional advantages over that construction. As in my earlier design, the present invention is specially suitable for use with l2 point socket wrenches and is preferably molded in one piece from suitable resilient elastomeric material, such as polyethylene or any of numerous plastic compositions having similar characteristics. The one piece accessory is formed with at least one and preferably two end rings lying parallel to one another and interconnected by at least one and preferably a plurality of leg members shaped and sized to fit within a respective point of a socket wrench with the inner face thereof disposed to frictionally engage the hex face of a fastener inserted into the wrench. In an illustrative embodiment of the invention the accessory is provided with six equidistantly spaced legs suitably disposed to occupy a hexagonally related set of wrench points leaving the remaining set of points available to seat a hex fastener part. The end rings are preferably spaced apart sufficiently to rest against the opposite end of a box type socket wrench and one of the rings is sufficiently flexible to permit its insertion into the well of a cylinder type socket wrench with the other ring lying flush against the entrance end of the cylinder. The accessory is installed and removed as quickly and as easily as a fastener itself without interfering with the use of the tool with the particular fastener size for which it was designed while greatly increasing the efficiency and utility of the wrench.
Accordingly, it is a primary object of the present invention to provide a new and improved inexpensive keeper accessory selectively usable with either box or cylinder type 12 point socket wrenches.
Another object of the invention is the provision of a one piece keeper accessory of resilient non-metallic molded stock adapted to be retained assembled by an interference fit with a socket wrench and readily installable and removable therefrom.
Another object of the invention is the provision of a hexagonal fastener keeper accessory for use with socket wrenches and usable interchangeably with box and cylinder type wrenches.
These and other more specific objects will appear upon reading the following specification and claims and upon considering in connection therewith the attached drawing to which they relate.
Referring now to the drawing in which a preferred embodiment of the invention is illustrated:
FIG. 1 is a side elevational view, partly in section, showing an illustrative embodiment of the keeper accessory in use on a typical 12 point box wrench;
FIG. 2 is a cross sectional view taken along line 22 on FIG. 1;
FIG. 3 is a cross sectional view showing the keeper accessory assembled to a typical 12 point cylinder type socket wrench;
FIG. 4 is a bottom end view of FIG. 3; and
FIG. 5 is a perspective view of the keeper accessory per se.
Referring now to FIGS. 1-5, there is shown an illustrative embodiment of the invention keeper accessory designated generally 10. As therein shown the keeper accessory is molded from suitable soft resilient elastomeric stock including rubber or a soft plastic composition. The keeper is preferably provided with a pair of end rings or ringlets 11,12 interconnected by at least one and preferably by a hexagonally-related set of radial legs or ribs 13 as is best shown in FIGS. 2 and 4. Legs 13 have flat exterior faces 14,14 interconnected between their remote edges by an inwardly bulging surface 15 adapted to have an interference fit with the face of a hex nut or bolt head 18.
Ringlet 11 at one end of the keeper accessory is provided with a low-height radial flange 20 adapted to engage over the end face 21 of a box wrench head 22. However, flange 20 is not sufficiently long to interfere with the assembly of accessory 10 into one end of a cylindrical 12 point socket 25. The ringlet 12 at the other end of the accessory has a somewhat wider radial flange 26 seatable against the other end of a box wrench head or against the outer end of a cylindrical socket head. It will be understood that the device is used with a 12 point socket wrench of either the box type or the cylinder type in order that one set of hex points can be usedto accommodate legs 13 while the other set of hex points is available to seat a fastener. The inner surface of a ringlet 26 is preferably of hexagonal shape as indicated at 29 in FIGS. 2 and 4.
In use, accessory 10 is inserted into the 12 point opening of either a box wrench 30 or one end of a cylinder type socket head 25. When assembling the accessory to a box wrench the ringlets 11,12 seat flush against the opposite end faces of the wrench head. However, in the case of the cylinder socket, ringlet 11 is deformed slightly as it is pressed into the socket. In either case the faces of the hex fastener part, such as bolt head 32, have an interference press fit with the inwardly bulging portions 15,15 of legs 13. The bulging faces are flattened somewhat as the outwardly facing surfaces 14,14 are pressed into a snug interference fit with the point areas of the wrench head. Because of the much greater surface contact between the points and the surfaces 14,14 than between surfaces 15 and the hex faces of the fastener, it will be readily apparent that the keeper displays no tendency to become disassembled during removal of the wrench from the fastener part. However, once the fastener is removed from the accessory the latter may be readily and expeditiously withdrawn by collapsing the same inwardly. The accessory may then be transferred to a different wrench if so desired.
While the particular keeper for socket wrenches herein shown and disclosed in detail is fully capable of attaining the objects and providing the advantages hereinbefore stated, it is to be understood that it is merely illustrative of the presently preferred embodiment of the invention and that no limitations are intended to the detail of construction or design herein shown other than as defined in the appended claims.
