DESCRIPTION OF THE DRAWINGS
The invention is not limited to the illustrated embodiments. In general the invention is a wrench made of a heavy and rust-resistant (laser cut in a preferred embodiment) steel, which is 7-gauge in a preferred embodiment, as well as zinc coated in a primary embodiment, formed to one of the water filter sizes, including but not limited to: SW1, SW2, SW3, SW5-a, 144880 BW-BC, C-shaped (open end) Universal style, S3072, HT-HTF, OW1, OW2, OW6. The standards, regarding the dimensions and other features of these wrenches are known in the art, and are incorporated by reference herein. A fuller description of the specific types and manufactures, not meant to be exhaustive, is included here in Appendix I.
Additionally, the inventive wrench is also compatible with different brands such as Culligan, Ametek, US Filter, Plymouth, Keen Plus, American Plumber, Bruner and many other brands. Furthermore, the invention is not limited to a particular size or configuration or brand.
FIGS. 1A-E shows a primary embodiment, a style of wrench, made of rust-resistant steel. The weight and sturdiness of the material allow for ease of use and durability for long-term storage, which makes the wrench appropriate for both intermittent at-home use and for the professional.
FIG. 1A illustrates a Superb WrenchTM which is a primary embodiment of the invention. As stated above, the invention is made to replace inferior, breakable plastic wrenches, but without a substantial cost to the end consumer, because it is easily manufactured and lasts for a long time. The wrench has a long handle H which is typically between 1.5 and 2 times the diameter of the head HE of the wrench. The handle H include an easily applied and comfortable Grip G, which in the present embodiment is shown as made of a hollow PVC tube which slides over the handle. The handle H also has some indicators formed or cut into it to help the user. These include a designator D, shown by the broken circle, and a label L to help the novice or occasional user to operate the wrench. Alternate embodiments may not keep the feature where the handle is 1.5-2 times the diameter of the head HE. Particularly, where the wrench head is particularly large.
The head HE can be of various specifications, as stated above. The embodiment shown has six openings O1, and is shown to be of the SW-1A type water softener wrench. FIG. 1B illustrates the details of the head of the water softener wrench in a primary embodiment. The manufacturing process of the material of which the wrench is made allows for different features to be implemented on the inside surface IS and the opening surface OS. However, in a primary embodiment the head HE shown is suitable for the use of removing a difficult to dislodge water softener filter.
FIG. 1C illustrates the water softener filter wrench in a first embodiment from a side view. Features of the material used are shown in the illustration, however, such features are dependent on the manufacturing process of the wrench and may be different in an alternate embodiment. FIG. 1D illustrates the features of the “neck” of the water softener filter wrench, or the junction of the handle and head. The label L is shown imprinted into the neck area for easy visibility and understanding as turning the water softener filter the wrong way could cause damage.
FIG. 1E shows that the wrench includes a PVC grip G on the handle, allowing for ease of use and for comfort on the hands. There is a small portion OE of the grip G that allows for easy addition and/or replacement and is generally easy to grip and also allows for thermal protect of the hands away from a very cold (or very hot) steel wrench. Although shown in black, there may be variations of the PVC grip G as may be aesthetically pleasing or even a coding system. Like PVC there also may be useful printing on the grip sleeve G.
FIG. 2 illustrates the water softener filter wrench in an alternate embodiment. The alternate embodiment (shown as Superb WrenchTM No. 3) is a different water softener filter standard SW2 in the wrench head HE′. Most of the features of the alternate embodiment are similar to those described above for FIGS. 1A-1E, with the exception of the wrench head. FIG. 3 illustrates a second alternate embodiment (shown as Superb WrenchTM No. 7), and, once again, has similar features to the wrenches shown in FIGS. 1A-2. The second alternate embodiment has a small square aperture in the wrench head HE′′ and is used on the appropriate water softener filter. The wrench head HE′′ of the second alternate embodiment is much small proportionally than the wrenches shown above.
FIG. 4 illustrates a variety of embodiments of the wrench for various standards and manufactures of water filters. The various wrench fitting are described herein, but limited to those listed. The filter fitting means are described further in Appendix I below.
