Clamping assembly

a technology of assembly and rudder, which is applied in the field of rudder assembly, can solve the problems of reducing the service life of the rudder, and requiring the replacement of the rudder, and reducing so as to reduce the potential for the rudder to loosen, reduce the drag and eliminate the effect of stripping

Benefits of technology

The clamp assembly described in this patent has a nut that connects to the screw, allowing for tightening and close tolerances during engagement. The cutout in the bottom of the body also prevents stripping. The body has a protuberance that slides along the top surface of the fin box, allowing for positioning of the rudder closer to the ends of the fin box. Additionally, the clamp handle tapers away from the clamp head to an end, reducing the profile of the clamp and limiting drag. These features improve the efficiency and maneuverability of the clamp assembly.

Problems solved by technology

On occasion, rudders break and / or need to be replaced or they need to be removed for transportation and storage.
Presently this process is difficult requiring the use of a number of small pieces that need to be aligned that can easily become lost in cold, wet, and sandy conditions.
Not only is the process difficult and time consuming, it is also frustrating.
Another issue present in the art is allowing for the fine-tune adjustment of the rudder's position on the aquatic device.
Currently, there is no simple and straightforward way to accomplish such adjustments.
As a result, the rudder is maintained in a constant position that may not be suitable for all water and wave conditions.
Although this limits the number of parts, the use of such devices make it likely that the positioning of the rudder will change due to the loosening of the screw or thumbscrew.
Also, the need to tighten such connections firmly can result in difficulties in removing the screw or thumbscrew—especially in instances where assistive tools are not available.
Despite these advancements, problems still remain.
As a result of the use of plastic, the threaded screw strips the plastic if the threaded screw is screwed too far into the bottom and then excessive force is applied to the clamp handle.
Some riders or surfers also take issue with the size of the body used in the clamp assemblies as it does not always permit the entire length of the retaining slot in the fin box to be utilized.
As a result, rudders cannot be positioned as far to either side of the fin box as some would like.
Further, the use of a clamp can increase drag in the water due to the size and profile of the clamp handle that extends substantially, if not entirely, outside of and away.

Embodiment Construction

[0033]Referring to the Figures, a clamp assembly 10 for securing a rudder 12 to an aquatic device 14 has a body 16 having a first end 18, a second end 20, a top 22 and a bottom 24. A slot 26 that extends from the first end 18 into the body 16 has a first section 28 and a second section 30. The height of the first section 28 of the slot 26 is greater than the height of the second section 30 which creates weakness within the body 16 for clamping. The slot 26 forms a bottom finger 32 between the slot 26 and the bottom 24 of the body 16. Positioned along the finger 32 is at least one and preferably two pins 34 that extend outwardly and transversely to the body 16. Also, the tip 36 of the finger 32 at the first end 18 is curved or chamfered.

[0034]The top 22 has a first section 38 and a second raised section 40 that are separated by a shoulder 42. Preferably, the raised section 40 corresponds with the second section 30 of the slot 26. A threaded or unthreaded bore 44 extends through the r...

Abstract

A clamp assembly for connecting a rudder to an aquatic device having a body with a first end, a second end, a top and a bottom. A clamp having a screw connected to a pivot pin disposed within a clamp head is removably connected to the top of the body for selectively applying a clamping force on the body. The clamp handle in some bodies tapering to an end to allow placement within a retaining slot of a fin box.

CROSS-REFERENCE[0001]This application is a continuation-in-part of pending application Ser. No. 16 / 181,654, filed Nov. 6, 2018, which is a continuation-in-part of pending application Ser. No. 15 / 812,215, filed Nov. 14, 2017, the contents of this application is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention is directed to a clamping assembly, and more particularly, a clamping assembly for connecting a rudder to an aquatic device.[0003]Rudders for use with aquatic devices such as paddle boards, surf boards, and the like are well-known in the art. On occasion, rudders break and / or need to be replaced or they need to be removed for transportation and storage. Presently this process is difficult requiring the use of a number of small pieces that need to be aligned that can easily become lost in cold, wet, and sandy conditions.
