1. Technical Field
This invention relates to a hexagonal driver and, more particularly, to a multifunctional hexagonal driver including a ratcheting mechanism.
2. Prior Art
Socket wrenches, including a drive tool and socket, are commonly used to turn fasteners, such as nuts and bolts. A first end of the socket is placed over the bolt and the drive tool is inserted into a second socket end. A user then applies force directly to the drive tool for rotating the bolt.
A standard socket set includes a number of sockets each having different first end sizes for accommodating a variety of sizes of bolt heads and other like fasteners. Commonly, the sockets are dimensioned according to the common sizes of fasteners, such as the metric or English systems. The second socket end attaches to the drive tool and may have a variety of sizes, depending upon the manufacturer, year of manufacture, first socket end dimensions, and the like. Each of the second ends is substantially rectangular in shape, but there are no standardized sizes or dimensions. Regardless, all these components, including the sockets themselves and the socket wrench, consume a considerable amount of space within an individual's work area.
Furthermore, a lot of time can be wasted in trying to figure out which socket must be used on a particular hexagonal nut or bolt and then fitting the correct socket onto the wrench. This results in loss of productivity for individuals using the conventional socket wrench at their workstation or wherever they may be performing their task. With a large number of loose sockets it is also possible to easily drop and loose a particular sized socket as the individual is performing their task, thus resulting in the necessity to replace the lost socket which can be expensive in the long run.
Accordingly, a need remains for a multi-functional hexagonal driver in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing a driver that has a convenient multi-function design, is portable and easy to store, cost-effective, and results in considerable time savings when used. Such a wrench eliminates the need to switch between drivers, saving time and improving productivity. The present invention will be appreciated by professional trades-people as well as do-it-yourselfers.
In view of the foregoing background, it is therefore an object of the present invention to provide a multifunctional hexagonal driver. These and other objects, features, and advantages of the invention are provided by an apparatus for tightening and loosening various sized fasteners. The apparatus includes a driver section formed from rigid material that has a centrally disposed bore provided with a longitudinal axis extending along a partial length of the apparatus.
The driver section includes a plurality of unique driver heads having various sizes for engaging the fasteners during operating conditions. Such driver heads are radially spaced about the axis and maintain a concentric relationship when adapted between extended and retracted positions. Advantageously, the plurality of driver heads are removably positionable within the bore so that a user can selectively access alternate ones of the driver heads as desired.
The driver includes a mechanism for securing the driver heads to the housing and a mechanism for adapting the driver heads between extended and retracted positions. Such a securing mechanism preferably includes a plurality of fingers integrally extending from the driver heads. The housing is provided with a plurality of notches for receiving the fingers therein and for advantageously maintaining the driver heads at a substantially stable position during operating conditions. The adapting mechanism preferably includes a plurality of resilient springs operably connected to the driver heads and disposed distally of the sleeve. Such springs are compressed and relaxed when the driver heads are toggled between corresponding retracted and extended positions.
A handle section having a bore formed therein is included for effectively receiving the driver section therein. Such a handle section includes a sleeve slidably positionable thereover for providing a convenient gripping surface onto which a user may grasp the apparatus. An elongated socket is formed at a proximal end portion of the handle section and extends distally along the axis such that an auxiliary driver can be removably secured thereto. The auxiliary driver can rotate select ones of the driver heads without requiring a user to maintain contact about the sleeve. The socket includes a ball bearing extending radially and inwardly therefrom. The sleeve preferably includes an outer layer formed from rubber material for conveniently providing frictional support.
The apparatus may further include a locking mechanism for conveniently toggling the handle section between stationary and rotatable positions so that a user can operate the apparatus in a ratcheting manner. The locking mechanism preferably includes a switch situated on an outer surface of the handle section including an arm extending downwardly into the handle section and a toothed gear disposed about the axis and subjacent to the arm wherein the gear is axially rotatable between selected directions when the switch is moved to a predetermined position. Such a gear is slidably engageable with the arm when the switch is moved to a predetermined position and the gear is stationary and abutted with the arm when the switch is moved to an alternate position. The locking mechanism may further include a spring steel member having opposed end portions secured to the handle section and the arm respectively.
The novel features believed to be characteristic of this invention are set forth with particularity in the appended claims. The invention itself, however, both as to its organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description taken in connection with the accompanying drawings in which:
The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which a preferred embodiment of the invention is shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiment set forth herein. Rather, this embodiment is provided so that this application will be thorough and complete, and will fully convey the true scope of the invention to those skilled in the art. Like numbers refer to like elements throughout the figures.

Advantageously, this feature prevents the driver heads 21 from slipping about the fasteners, which is a common problem with conventional drivers. The adapting mechanism 40 includes a plurality of resilient springs 41 operably connected to the driver heads 21 and disposed distally of the sleeve 62 (described herein below). Such springs 41 are compressed and relaxed when the driver heads 21 are toggled between corresponding retracted and extended positions.

The socket 63 includes a ball bearing 64 extending radially and inwardly therefrom. The sleeve 62 includes an outer layer 65 formed from rubber material for conveniently providing frictional support. Such an outer layer 65 advantageously prevents the apparatus 10 from slipping out of the user's hand, thereby preventing the apparatus 10 from being damage.

While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation. The assembly and use of the present invention are deemed readily apparent and obvious to one skilled in the art.
