The following includes information that may be useful in understanding the present invention(s). It is not an admission that any of the information provided herein is prior art, or material, to the presently described or claimed inventions, or that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of wrench devices and more specifically relates to a standard ratchet wrench assembly having a handle socket member adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon the standard ratchet wrench assembly when in use.
A socket wrench is a type of wrench or spanner that has a socket attached at one end, usually used to turn a fastener. The most prevalent form is the ratcheting socket wrench, often informally called a ratchet. A ratcheting socket wrench is the device within a hand tool in which a metal handle is attached to a ratcheting mechanism, which attaches to a socket, which in turn fits onto a type of bolt or nut.
Pulled or pushed in one direction, the ratchet loosens or tightens the bolt or nut attached to the socket. Turned the other direction, the ratchet does not turn the socket but allows the ratchet handle to be re-positioned for another turn while staying attached to the bolt or nut. This ratcheting action allows the fastener to be rapidly tightened or loosened in small increments without disconnecting the tool from the fastener. A switch is built into the ratchet head that allows the user to apply the ratcheting action in either direction, as needed, to tighten or loosen a fastener. Other common methods of driving socket wrenches include pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers and breaker bars. Some lesser known hybrid drivers include striking wrench tools with square drive, and hydraulic impact wrenches (typically powered by on site hydraulic power such as present with military tanks, and many rail car applications).
Socket wrenches are most commonly hexagonal, or more commonly referred to as “6-point” in lay terms. Sockets are driven by being attached to the driving tool via a male/female square connection fitting (called the square drive). Standard sizes of square drives around the world include ¼″, ⅜″, ½″, ¾″, 1″, 1½″, 2½″ and 3½″ square drive sizes (a de facto international standard with no metric equivalents along with some lesser used drivers such as ⅝″ square drive, and both #4 and #5 spline drives specified in ANSI B107 specifications. This wide range of square drive sizes provides for a wide variety of socket types and sizes to suit small to very large nuts and bolts. Some square drivers have a through hole to attach the socket to the driver (using a retaining ring with o-ring and pin type, or single piece molded retaining rings), a locking pin, or friction ball. Some common hand ratchets employ a quick release button on their top for quick socket release of smaller sockets.
The tool chosen to drive the socket wrench ultimately supplies the mechanical advantage needed by the user to provide the torque needed to loosen or tighten the fastener as may be required. Larger drivers are typically used with higher torque, while smaller drivers are used for convenience in smaller low torque applications. Given the limits of human strength and fatigue, torque above 600 ft-lbs of torque will generally involve some kind of power assist, instead of the user simply pushing on the handle of a wrench. Very large sockets and drivers are typically powered by hydraulics to achieve torque.
A socket is typically a cylinder which has a female six- or twelve-point recessed opening sized to fit over the common male hexagonal head of a bolt or nut fastener. The opposite end of the socket wrench has a standardized (ANSI B107, ISO, or other consensus standard) square recess to accept the socket wrench's drive size. Male drivers are also produced for use with socket head cap screws, and are often called Allen drivers (trademark) or the generic term male bit drivers.
The principal advantage of interchangeable sockets is that, instead of a separate wrench for each of the many different fastener sizes and types, only separate sockets are needed for each size and type. Because of their versatility, nearly all screw and bolt types now have sockets of different types made to fit their bolts or nuts. Sockets often come as a “socket set” with many different sizes or types of sockets to fit the heads of different-sized fasteners.
Unfortunately, existing wrenches lack both the ability to be used as a crank and to be stored on a workstation pegboard for easier access. Therefore, a need exists for a tool that gives a user the option of operating the wrench with a spindle attachment making tightening and loosening nuts or bolts easier and faster, and have the ability to be hung and stored.
Various attempts have been made to solve the above-mentioned problems such as those found in U.S. Pat. No. 4,104,935 to Roscoe D. Stoops; U.S. Publication Number 2004/0025649 to Frederick Rugee; U.S. Publication Number 20160318170 to Gerald Shane Mulligan; U.S. Publication Number 20040055428 to Donald Cooper; and U.S. Pat. No. 6,308,596 to Elden Williams. This art is representative of torque enhancing devices for wrenches. None of the above inventions and patents, taken either singly or in combination, is seen to describe the invention as claimed.
Ideally, a standard ratchet wrench assembly should be user-friendly and safe in-use and, yet should operate reliably and be manufactured at a modest expense. Thus, a need exists for a standard ratchet wrench assembly having a handle socket member adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon the standard ratchet wrench assembly when in use and to avoid the above-mentioned problems.
In view of the foregoing disadvantages inherent in the known wrench device art, the present invention provides a Standard Ratchet Wrench Assembly (Entitled Spin Wrench). The general purpose of the present invention, which will be described subsequently in greater detail is to provide a standard ratchet wrench assembly having a handle socket member adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon the standard ratchet wrench assembly when in use.
In a standard ratchet wrench assembly having a handle portion and a head portion located on a distal end portion thereof, and wherein the head portion includes a ratchet socket member therein, the improvement comprising a handle socket member. The handle socket member is located within a proximal end portion of the handle member. The handle socket member is adapted to rotate within the proximal end portion of the handle member. The handle socket member is adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon the standard ratchet wrench assembly when in use.
The present invention holds significant improvements and serves as a Standard Ratchet Wrench Assembly (Entitled Spin Wrench). For purposes of summarizing the invention, certain aspects, advantages, and novel features of the invention have been described herein. It is to be understood that not necessarily all such advantages may be achieved in accordance with any one particular embodiment of the invention. Thus, the invention may be embodied or carried out in a manner that achieves or optimizes one advantage or group of advantages as taught herein without necessarily achieving other advantages as may be taught or suggested herein.

Generally speaking, the Spin Wrench comprises a modified wrench improving the original use of the wrench tool. A hole is casted onto the handle of the wrench, and a free rotating socket is pressed into position in the hole. It is used like a crank, rotating on an axis. A regular socket wrench has a detachable socket at one end designed to tighten and loosen nuts and bolts of particular sizes. A ratchet wrench works as a tool used to apply torque to specific fasteners, nuts, and bolts. The Spin Wrench is designed to work as a double-sided wrench where one side uses a standard drive extension and a socket to fasten nuts and bolts, and the other side uses a standard drive extension to apply torque to certain fasteners and screws.
The unique features of this product provide the following benefits for people everywhere.
