Abstract

A boat motor propeller wrench with metallic motor nut fastener is described. The wrench includes a polymer handle including a first end and a second end opposite the first end, the second end including a tethering aperture. The wrench also includes a socket formed as one piece with the handle and extending from the first end of the handle substantially perpendicular thereto, the socket defining an aperture. The wrench further includes a metallic insert disposed within the aperture of the socket.

6. The boat motor propeller wrench of claim 1, wherein a ratio of a length dimension of the polymer handle to the first diameter is 12:1.

7. The boat motor propeller wrench of claim 1, wherein the metallic insert is molded into the socket.

8. The boat motor propeller wrench of claim 1, wherein the metallic insert is coupled with the socket.

9. The boat motor propeller wrench of claim 1, wherein the polymer handle comprises integrated flanges on opposite sides of the polymer handle to reinforce the polymer handle.

10. The boat motor propeller wrench of claim 1, further comprising a gap between the aperture and the metallic insert.

11. The boat motor propeller wrench of claim 10, further comprising an adhesive layer filling the gap between the aperture and the metallic insert.

DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) In referring to the drawings, and in particular FIG. 1, the “Propeller Wrench with Metallic Motor Nut Fastener” 1 is readily disclosed. It has a handle portion 2, integrally made with the socket part 3 which generally is perpendicularly aligned with the handle, when formed. The handle has various reinforcing flanges, as at 4 and 5, to share its retention to the socket, particularly when substantial force is applied to the handle, to obtain leverage upon the socket as it tries to dislodge, or fix during installation, of the propeller nut, during its manipulation. While not shown, the handle may have a length of reinforcing rod or bar, generally internally as noted at 6, in order to give further strength to the wrench, for application when substantial force is applied to it, particularly when attempting to extract the propeller nut, as at N, from the motor, during servicing.

(11) As can further be seen, the back end 7 has an aperture 8 provided therethrough, into which a tethering cord T, or other linkage, can be applied, so that the device can be secured, at its opposite end, to the user, such as around a belt, or the like, or any type of wristband, as known in the art. Many times, the propeller needs to be removed on the spot, such as when it encounters a rock and shatters a blade, and must be removed, and replaced with another propeller, sometimes even when the boat may be on the water, at a shore, or at the dock, when such a predicament necessitates propeller service.

(12) The opposite end of the wrench, or the socket feature 3, as previously defined, includes a central aperture, as at 9, provided extending therethrough, which at the upper segment, is formed to a depth of approximately an inch or two, and generally will be molded into a hexagonal configuration, in order to receive the hexagonal shaped insert, as shown at 10, as noted in FIG. 8. This insert 10 is formed of metal, while the remainder of the wrench body may be molded from a hard polymer, such as polypropylene, or a related hard type of polymer, that can be used for forming the configuration of the wrench body, as noted. Preferably, the hexagonal insert 10 will be formed of stainless steel, so as to resist corrosion, particularly after repeated usage when exposed to wet and water conditions, during its application and removing or setting a propeller onto its motor, during servicing. It can be pressure fitted, molded or adhesively applied to the wrench handle.

(13) The bottom of the aperture 9, as can be seen in FIG. 2, is formed of a square configuration, as noted at 11, so that any water that gets into the aperture 9, of the socket, can quickly drain out, while the wrench is being used.

(14) As can also be seen in FIG. 3, the socket 3, and its aperture 9 holding the insert 10 in place, may also have some quantity of adhesive, as at 12, to further aid in holding the insert 10 in place, so that it does not slip, or strip the interior opening 9 of the socket, when excessive force is applied to the wrench, during its usage.

(15) One can see the relative dimensions between the handle 2 of the wrench, and the height of its socket 3, as noted in FIGS. 4 and 5, and similar views can be taken from the FIGS. 6 and 7 embodiments, showing the front and back views of the wrench.

(16) It has been determined that with the length of the handle, in addition to its socket, and in particular the distance between the interior sides of the hexagonal insert 10, provides a leverage of approximately 12:1, in the transition of the force from the handle transmitted to the socket, during its usage. This provides a substantial enhancement of the force, and provides the need for reinforcing the interior of the socket, through the use of the metal insert, so as to prevent a stripping of the socket of the wrench, as it exerts such excessive force upon the propeller nut, during its removal, or installation.

(17) Variations or modifications of the subject matter of this invention may occur to those skilled in the art upon review of the disclosure as provided herein. Such variations, if within the spirit of this invention, are intended to be encompassed within the scope of any claims to patent protection issuing herein. The review of the invention and the summary and its description of the preferred embodiment, and as shown in the drawings, are set forth for illustrative purposes only.
