Boat Propeller Wrench with Embedded Metallic Motor Nut Fastener

Abstract

A boat propeller wrench with metallic motor nut fastener, the wrench being formed of a molded polymer, having a handle portion, and a perpendicularly arranged integral socket, the socket having an aperture provided at least partially therein, forming a bore, and into which a metallic insert is located and applied for securement about a boat propeller nut, as it is being loosened, and removed, or tightened upon application, when the propeller is being serviced. The handle to socket leverage provides an approximate 12:1 force ratio, that greatly enhances the force exerted upon the nut, through manipulation of the wrench handle, as the nut is being removed, or installed, after servicing of the boat motor propeller. The back end of the handle has an aperture provided therethrough, and to which a tether device may be secured, to allow the wrench to be tied down, and to prevent its loss in the water in the event of untimely slippage from the hand of the service technician.

Claims

1. A boat motor propeller wrench having a handle, and an integral socket, the socket being substantially perpendicularly arranged with respect to the handle, with a handle to socket ratio providing a leverage of approximately 12:1 in the force transmission from the handle, to the socket, when applied to the nut of a boat propeller, said socket having an aperture at least partially provided centrally therein, and a metallic insert provided within the socket aperture, to provide significant grip upon the propeller nut, as force is exerted upon the wrench handle to provide for its removal or installation of the propeller nut, during servicing, and said wrench is formed of a polymer.

2. The boat propeller wrench of claim 1, wherein the metallic insert is hexagonally shaped, and extends for some length into the formed aperture of the socket of the wrench, the formed aperture of the socket also having a hexagonal shape, internally of the socket, and into which the hexagonal metallic insert locates to reinforce the wrench as it is forcefully applied to the propeller nut during its installation and removal during servicing, and said wrench is formed of a polymer.

3. The boat motor wrench of claim 2, and including an adhesive provided within the socket aperture, to further secure the metallic insert in place within the socket during assembly.

4. The boat motor wrench of claim 2, wherein the metallic insert is pressure fitted within the socket aperture during its assembly.

5. The boat motor wrench of claim 1, wherein the handle and its integral socket are formed of a polymer.

6. The boat motor wrench of claim 5, wherein the polymer is a hardened polypropylene.

7. The boat motor wrench of claim 1, wherein the opposite end of said handle has an aperture provided therethrough, and to which a tether may locate to provide for tie-down of the wrench during its usage.

8. The boat motor wrench of claim 1, wherein the handle includes a metal reinforcing rod to strengthen the handle during its usage when excessive force is applied in the application or removal of the propeller nut from the boat motor.

9. The boat motor wrench of claim 2 wherein said metallic insert is molded into the wrench socket.

10. The boat motor wrench of claim 2 wherein said handle has integrated flanges to reinforce said handle during usage.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] 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, from the motor, during servicing.

[0028] As can further be seen, the back end 7 has an aperture 8 provided therethrough, into which a tethering cord, 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.
