This invention generally relates to the field of hand tools and more particularly, this invention relates to hand tools used for screwing and torquing.
Screw drivers have been around for a very long time, in one form or another. They are among the most useful and widely available tools in existence. They are essential to workmen, both professional and lay workers.
On occasion various screw drivers are used for excessively heavy torquing loads. In such cases, the handle of the screw driver in and of itself is insufficient to cause the desire torque on a screw. Often times, the user will continue to attempt to turn the screw, damaging either or both of the screw and the working end of the screw driver.
Thus what is needed is a tool which enables the user to apply more force on the screw driver to effectively turn such screws without damaging either the screw driver or the screw itself.
An improved screw driver which includes structure for applying additional torquing force to the handle for turning a screw. In a first embodiment, the screw driver includes a torquing member and the screw driver having torquing member openings through which the member engages the screw driver.
It is an object of this invention to provide an improved screw driver which uses the basic structure of a conventional screw driver and adapts to engage a torquing member to provide additional torquing.
It is an additional object of this invention to provide a conventional screw driver having modifications to adapt to engaging a torquing member that do not change the basic characteristics of the screw driver and to provide an additional torquing member opposed handle for added torquing capability.
The structure in accordance with this invention, comprises:
In another exemplary embodiment, the screw driver structure has a plurality of torquing member openings at different angles to the longitudinal axis of the screw driver. Different openings are used to apply different torques to the handle and hence the screw.
In another exemplary embodiment, the torquing member includes a second end and the second end includes a secondary handle and wherein the second end of the torquing member is adapted for connection with the secondary handle.
It will be appreciated that the second end gives the user the ability to apply even more torque to the screw driver of the instant invention without requiring the user to have additional strength. The user can apply substantially greater amounts of torque to the handle and consequently the screw being engaged by the working end of the screw driver.
It is an advantage of this invention to provide such an improved screw driver, which allows greater amounts of torque to be applied to the working end of a screw driver without changing the basic character of the screw driver.
It is an additional advantage of this invention to allow the user to apply torque at different angles.
For a further understanding of the objects and advantages of the present invention, reference should be had to the following detailed description, taken in conjunction with the accompanying drawing, in which like parts are given like reference numerals and wherein:
An exemplary embodiment of the improved screw driver in accordance with this invention generally denoted by the numeral 20 will now be described with reference to
The torquing member 24 has a first handle 32 and an elongated member 34. The elongated shaft member 34 is designed and adapted to fit smoothly through the opening 30. Upon being fit through the opening 30, the user can, when appropriate turn the screw driver member handle end 26 by appropriate movement of the torquing member 24.
As seen in
In the exemplary embodiment shown in
For example, within the spirit and scope of this invention, the second end 44 and the secondary handle 46 may be force fit or a Velcro fit may proved useful. The primary concern is that the secondary handle be fit for the purpose intended, namely to provide additional torquing force to the screw driver member 22 and to be releaseably connected thereto.
While the foregoing detailed description has described several embodiments of the improved screw driver in accordance with this invention, it is to be understood that the above description is illustrative only and not limiting of the disclosed invention. Particularly, there are numerous structures for adapting the secondary handle of the torquing member to the second end of the torquing member after the torquing member is engaging the screw driver member. Not all of these possibilities have been described above. Nevertheless, all are within the spirit and scope of the invention. Similarly, a number of openings may be provided in the handle of the screw driver member without affecting the integral structure of the member. Not all the holes or angles possible have been described above. Yet, as set forth above, all such variations are indeed within the spirit and scope of the invention of the improved screw driver herein. Thus, the invention is to be limited only by the claims as set forth below.
