Wrench device

#1. Field of the Invention

#The present invention relates to hand held wrench devices in general and more particularly to a hand held wrench having an elongated handle and including a plurality of different size wrench openings located at one or both ends of the wrench handle. The wrench device is configured so as to retain normal wrench “feel” regardless of t he wrench opening being used and for applying substantial torque capabilities in various environments and restricted working areas.

#2. Description of the Prior Art

#FIG. 1 is a perspective view of the wrench;

#FIG. 2 is a plan view of the wrench;

#FIG. 3 is a left side edge elevational view of the wrench of FIG. 2;

#Referring to the drawings, a wrench device according to the present invention is indicated generally at 10. The wrench 10 of the illustrated embodiment may comprise a single piece body indicated generally at 11 constructed of steel or suitable alloy having sufficient hardness, heat treated or otherwise, to withstand the stresses to which the wrench is to be subjected according to its design criteria. The wrench body may be fabricated by such means as cold forging, stamping, laser cutting from flat stock or casting. The manufacturing method may depend upon the desired thickness of the wrench body or other limitations such as the manufacturing cost and materials used in the manufacture. As illustrated in the preferred embodiment, the wrench body is preferably manufactured from ¼″ flat stock, having two parallel faces 12 and 13 respectively. The wrench body includes an extended handle 14 and enlarged wrench areas located at opposite ends thereof.

#Although the illustrated embodiment is generally flat and constructed of completely flat stock, it will be understood that this configuration is preferred for lube bay work and that other configurations of the wrench may require the end clusters of wrench openings to be offset from the wrench handle as previously explained. It will also be understood that, although the handle 11 is shown with parallel faces and side edges, embellishments or contour deviations from this configuration are possible and are contemplated within the spirit of the present invention which is not limited to the surface details.

#As seen in the drawings, the top end of the wrench, as viewed in FIG. 1, includes an enlarged area 15 having a generally curvilinear or lobed circumferential edge 16 for mounting a first plurality of wrench openings. The bottom end as viewed in FIGS. 1 and 2 includes a second enlarged end area 17 also having a curvilinear or lobed edge 18. The exact outline of the edges 6 and 18 may be varied as a matter of design or appearance while accommodating the preferred placement and size of the wrench openings as presently to be described in detail.
