UNIVERSAL STEM SHAFT HANDLE

BACKGROUND OF THE INVENTION
Field of the Invention

The present invention generally relates to stem shaft handles and more particularly relates to valve stem shaft handle devices which can be removably coupled to a stem shaft of universal size, configuration, and condition.

Description of the Related Art

People around the world encounter broken handles of water valves, particularly exterior spigots used for hose connections, which typically have valves with relatively small diameter stem shafts having damaged splines which make it difficult for mating with conventional replacement handles. It is often difficult to find replacement valve handles that properly fit the varying sizes of the valve stem shafts. In addition to being small, typical valve handles are smooth and slippery when wet. As a result, they are difficult to grip adequately to open or close the valve. Since the valve handles are oftentimes located close to an obstruction, slippage can cause abrasion injuries to the operator's hand. These problems are especially difficult for people with reduced or impaired gripping strength, such as some of the elderly or people afflicted with arthritis or other debilitating conditions.

A variety of different types of handles are frequently employed in efforts to grasp and retain stem shafts.

Many such handle devices are not easily securable to damaged stem shafts of variable sizes. While these conventional units may be suitable for the particular purpose employed, they would not be as suitable for the purposes of the present invention as disclosed hereafter. None of such conventional devices disclose the unique structures and advantages of the present disclosure.

A need exists for valve handle devices that will help to more easily replace broken handles for valve stem shafts of nearly universal size and for damaged valve stem shafts, where the valve handles can better grasp various sizes of stem shafts as well as grasp damaged valve stem shafts.

A need exists for a valve handle device capable of universal application to valve stem shafts and splines of varying orientation and shape, and of varying thicknesses.

Accordingly, there is a need for a compact portable lightweight and strong valve handle apparatus for securely grasping and operatively rotating a valve stem shaft, which apparatus may be easily positioned and/or repositioned on the stem shaft at the option and intention of the user without complex assembly and setup.

As disclosed in this application, the inventor has discovered novel and unique devices and methods for securely grasping and operatively rotating a valve stem shaft of varying sizes and conditions, which exhibit superlative properties without being dependent on a particular spline configuration or difficult-to-find components.

The devices and methods disclosed herein avoid many of the drawbacks of existing methods and devices which rely on multiple tools and/or spline repair for application of the devices to the valve stem shaft.

Embodiments of the present invention provide for valve handle devices and methods as described and defined in the description below and in the annexed claims which provide for improved mobility, setup, and retention characteristics in order to efficiently grasp and engage valve stem shafts of various sizes, shapes, and conditions, in a multitude of environments.

Embodiments of the present invention also provide for ratchet handle devices and methods as described and defined in the description below and in the annexed claims which provide for improved mobility, setup, and retention characteristics in order to efficiently grasp, engage, and shafts of various sizes, shapes, and conditions, in a multitude of environments.

SUMMARY OF THE INVENTION

It is one prospect of the present invention to provide a novel universal handle of simple and effective application which can be applied to varying sizes and shapes of stem shafts and splines and efficiently connected to securely grasp and retain stem shafts and splines of different sizes and shapes, including damaged stem shafts and splines, for various types of water spigots, air tanks, and gaseous tanks.

Further objects of the invention are to provide universal stem shaft handles which are comparatively simple and efficient in their application to stem shafts and their operation of the respective valve, while remaining readily removable at the option of a user. It is also an aim of the present invention to provide an improved ratchet handle system that provides improved ergonomic use and is of economical construction while providing nearly universal fit for intended shafts, overcoming the complexities and limitations of conventional ratchet tools.

Another object of the present invention is to provide a handle which allows quick adjustment of the positioning of the handle upon the intended stem shaft or spline by allowing easy adjustment by a user of the universally fitting handle.

Yet another object of the present invention is to provide a handle device wherein the handle is in the shape of a sign element containing a character and/or other visually appealing design elements thereon, and wherein the handle device is easily attached and detached from the shaft at the option of the user.

Additional objects, advantages and novel features of this invention shall be set forth in the description that follows, and in part will become apparent to those skilled in the art upon examination of the following specification.
