DETAILED DESCRIPTION

[0021] Now, with reference to FIGS. 3A-5, there is shown an angle valve wrench 300 for transmitting a rotational force sufficient to operate an angle valve (such as valve 100 of FIG. 1, as shown in FIGS. 3, or valve 200 shown in FIG. 2), including from a standing position. Wrench 300 includes a body 302 having an outside surface 304, a length L1, and a central axis 306 that is parallel to length L1. Preferably, the length L1 is sufficient to allow a user to operate the wrench 300 from a standing or crouched position. In certain preferred embodiments, the length L1 is between 14″ and 30″. More preferably, the length L1 is 20″. The body 302 is preferably substantially cylindrical in shape and has an outside diameter between 1½″ and 2″. More preferably, the outside diameter of the body 302 is 1⅝″. However, in other cases, body 302 may be formed in other shapes and in other sizes. In certain further embodiments, the body 302 is hollow and includes an inside surface 322. Wrench 300 may be formed using any suitable material, including polyvinyl chloride (PVC) or other similar plastics, metal, or other sufficiently rigid materials (i.e., a material which does not deflect as a rotational force is applied about the central axis 306 when in contact with the angle valve 100).

[0022] Body 302 includes a first end 308 and a second end 310, and the central axis 306 extends through a center of each of the first and second ends. The second end 310 of wrench 300 preferably includes a gripping element 318 for assisting the user in gripping and applying a rotational force to the wrench 300. In certain embodiments, the gripping element 318 includes a plurality of protrusions, indentations, or other similar mechanisms or surface features to increase friction between a user’s hand and the outside surface 304 of the wrench 300. For example, in one illustrated embodiment, gripping element 318 is formed as strips of commercially available adhesive-backed sand paper that are overlaid onto the second end 310 of the wrench 300. In other embodiments, the gripping element 318 comprises a plurality of elongate grooves, ridges (FIG. 5), or other surface features that are formed into or onto the outside surface 304 of the second end 310 of the wrench 300. These gripping elements 318 are preferably equally distributed and circumferentially spaced around the outside surface 304 of the wrench 300 and may be spaced at an offset from the second end 310 by a distance D2. The offset distance D2 provides a location for additional features, including those detailed below. In certain preferred embodiments, the offset distance D2 is between 1″ and 2″. In certain cases, the gripping elements 318 may vary in number from 4 to 8 total grooves and may be approximately ⅛″ wide and approximately ⅛″ deep. Preferably, the grooves 318 have a length L2 this is sized to approximate the width of a user’s hand (e.g., approximately 2″ to 3″ wide).

[0023] In certain embodiments, the second end 310 may also include a torque-enhancer hole 320. Hole 320 may be located at any location along the body 302. However, preferably, the hole 320 is located within the offset distance D2 between the second end 310 and the gripping element 318. Hole 320 preferably passes perpendicularly through the entire body 302 and through central axis 306 in order to provide an insertion point for a rod 328 or other similar device to which a user may apply an increased turning (i.e., rotational) force onto the wrench 300. This increased turning force may sometimes be necessary or advantageous to rotating the wrench 300, such as when valve 100 is stuck. While a dedicated rod 328 may be provided, a screwdriver or other, similar implement will suffice to enhance the torque transmitted by the wrench 300. Preferably, the torque-enhancer hole 320 has a diameter between 3/16″ and ½″.

[0024] The first end 308 also includes a notch 312 that is formed by two opposing sidewalls 314 that are joined by wall 316. Preferably, sidewalls 314 are oriented vertically (as viewed in FIGS. 3) and are parallel with one another. On the other hand, wall 316 is preferably horizontal (as viewed in FIGS. 3). Further, wall 316 preferably extends continuously between and connects the sidewalls 314 together. The notch 312 is preferably sized and configured to engage a variety of valves, including valve 100 or valve 200, preferably, by the notch being placed over a valve such that the wall 316 contacts the handle 102 and at least one of the sidewalls 314 contact at least one of the sidewalls 104 of the handle. In the illustrated embodiment, the notch 312 has a width W1 that is the horizontal distance between the two vertical sidewalls 314. Width W1 is sized to allow the notch 312 to fit over the top of handles of a range of valves, including over handle 102 or over handle 202. In preferred embodiment, width W1 is sized such that the two sidewalls 314 contact the sidewall 104 of the valve 100 at a minimum of two locations as the wrench 300 is rotated about central axis 306.

[0025] With configured reference to reference to FIGS. 3A and 3B and with further reference to FIGS. 6 and 7, if width W1 is too large, notch 312 will not provide a secure connection with the valve 100. In particular, a notch 312 having a width W1 that is too large will be spaced too far from sidewalls 104 of the valve 100 and, for that reason, will allow for over-rotation of the wrench 300 before the sidewalls 314 contact the sidewalls 104 of the valve 100, which will provide too much “play” or “slop” in the use of the wrench during its use. Conversely, a width W1 that is too narrow will not allow the wrench 300 to correctly or adequately engage the handle 102 of the valve 100. Further, if width W1 is too narrow, the useable range of angle θ between the central axis 306 of wrench 300 and the stem 106 will be reduced. For example, if notch 312 is very narrow, it may be necessary to align central axis 306 with the stem 106 (i.e., angle θ equal 0°) in order for the wrench 300 to properly seat onto and to be capable of rotating the valve 100. Although this configuration might be acceptable in certain instances, it is often preferred or advantageous to operate the wrench 300 from a variety of angles and positions, including from a standing positon. As such, width W1 is preferably sized such that a user may engage a valve with wrench 300 at an angle θ, which preferably is between 0° and 30°, allowing the wrench to be used while the user is in various positions (e.g., standing, kneeling, etc.). In certain embodiments of the present invention, the width W1 of the notch 312 is between ½″ and 1″. More preferably, width W1 is approximately 15/16″.

[0026] In FIG. 6, each of the vertical sidewalls 314 of the notch 312 are parallel and the width W1 of the notch 312 is fixed (i.e., the same) between the inside surface 322 and the outside surface 304. On the other hand, in the embodiment shown in FIG. 7, vertical sidewalls 314′ are canted or tapered and are not parallel to each other. As such, a width W2 that is taken at the inside surface 322 is different (e.g., greater than or less than) than the width W1 that is taken (in this specific instance) at the outside surface 304. It may be appreciated that sidewalls 314 and 314′ engage the handle 102 of the valve 100 differently. Specifically, sidewalls 314 contact handle 102 at roughly the intersection 602 between the inside surface 322 and the sidewalls. On the other hand, tapered vertical sidewalls 314′ allow for greater contact between the sidewalls 314′ of the wrench 300 and the sidewalls 104 of the valve 100 handle. Sidewalls 314′ contact handle 102 at a tangent intersection 702 of the sidewalls and the handle. The increased contact area at intersection 702 provides for a more efficient transfer of rotational force from the wrench 300 to handle 102.

[0027] Returning to FIGS. 3, the depth D1 of the notch (i.e., the distance between the first end 308 and the horizontal notch wall 316) should be sized to allow the wrench 300 to adequately engage the handle 102. Proper engagement between handle 102 and wrench 300 includes contact between wall 316 and handle 102. A depth D1 that is too shallow does not allow the notch 312 to adequately contact the handle 102. On the other hand, too great a depth D1 can result in interference between the valve 100 and the wrench 300 such that rotation of the angle valve is difficult or, in some cases, impossible. In each case, if depth D1 is too shallow or too deep, the useable range of angle θ may be reduced. In certain embodiments of the present invention, the depth D1 is between ¼″ and 1″. More preferably, the depth D1 is ½″.

[0028] Now, each of FIGS. 4 and 5, depict the wrench 300 as seen from the first end 308. In the embodiment shown in FIG. 4, each of the vertical sidewalls 314 of the notch 312 are parallel and the width W1 of the notch 312 is fixed (i.e., the same) between the inside surface 322 and the outside surface 304. On the other hand, in the embodiment shown in FIG. 5, vertical sidewalls 314′ are canted or tapered and are not parallel. As such, in this second embodiment, the width W2 taken at the inside surface 322 is different (e.g., greater than or less than) than the width W1 of the notch taken at the outside surface 304.

[0029] As shown in FIGS. 6 and 7, sidewalls 314 and 314′ engage the handle 102 of the valve 100 differently. Specifically, sidewalls 314 contact handle 102 at roughly the intersection 602 between the inside surface 322 and the sidewalls. Tapered vertical sidewalls 314′ allow for greater contact between the sidewalls 314′ of the wrench 300 and the sidewalls 104 of the valve 100 handle. Specifically, sidewalls 314′ contact handle 102 at a tangent intersection 702 of the sidewalls and the handle.. The increased contact area of intersection 702 provides for a more efficient transfer of rotational force from the wrench 300 to handle 102.

[0030] In using the wrench 300, a user first locates the valve 100 the user wishes to close to stop water flow or open to start water flow. Upon locating valve 100, the user will hold the wrench 300 by the second end 310 and, preferably at the gripping elements 318, which provide the user with a secure area to grasp the wrench. The user then orients the first end 308 of the wrench 300 towards the handle 102 of the valve 100. Preferably, while in a standing positon, the user then engages the handle 102 with the wrench 300 by placing the first end 308 over the handle such that the angle valve handle fits within the notch 312. Ideally, the user is provided with positive feedback that the wrench 300 is correctly “seated” on the valve 100 when the horizontal wall 316 contacts the valve. Once the wrench 300 is correctly and fully seated on the valve 100, the user then rotates the wrench about the central axis 306 in the desired rotational direction (i.e., clockwise or counter-clockwise). As the user rotates the wrench 300, the vertical sidewalls 314 or 314′ contact the sidewall 104 of the valve 100 and translate a rotational force to the valve stem 106. If the handle 102 does not rotate or is difficult to rotate when a rotational force is applied to the wrench 300 (e.g., due to rust in or on the valve), the user may increase the applied torque by inserting rod 328, a screwdriver, or other similar device through the torque-enhancer hole 320 and then rotating the wrench using the device. This increased torque is generally sufficient to induce motion of the handle 102 in the desired direction. After rotating the handle 102 in the desired direction with the wrench 300, the wrench may be removed from the handle.
