Benefits of technology

[0008] The present invention is directed to a boat propeller cover having a housing that surrounds the propeller while it is affixed to the shaft, functions as a protective carrying case for the propeller when it is detached from the shaft, and has carrying handles that ease transport of the propeller.
[0011] The handles are preferably long enough to carry easily and comfortably, which in most cases, would be greater than 6 inches. The handles are made of a flexible fabric or any other suitable material that is easily grasped and comfortable to carry. It is advantageous that the handles are positioned on either side of the opening so that the propeller cover is balanced.

Problems solved by technology

First, the propeller blades are sharp and may cut someone.
Second, the propeller blades may become damaged if they are not protected when not in use.
However, this type of cover does not eliminate the dangers associated with propellers because the individual blade covers can easily be lost or misplaced, defeating the whole purpose of the cover.
Furthermore, the covered propeller does not make it much easier to carry because this type of cover does not immobilize the moving parts of the propeller.
Although this type of cover protects against the dangers associated with exposed sharp blades, carrying the propeller is difficult because the non-flexible material makes this type of cover is difficult to grasp and hold.
Also, the shape of this type of cover may be unwieldy.
The pockets may have various advantages, but they make the even more difficult and unwieldy to carry.

Embodiment Construction

[0016]FIG. 1 generally depicts a propeller cover 10 having a housing 20, a space 30 sized and dimensioned to receive a propeller, and handles 40 and 40A. The housing 20 has an opening 50 that is configurable between a open and closed conformation so that in the open conformation the cover fits around a propeller, and in the closed conformation, the opening fits snugly around a drive shaft. Each of these is discussed in detail below.

[0017] Housing 20 may be made of any suitable material that is durable, water-resistant, strong, rust proof, or light-weight. For example, the housing 20 can advantageously comprise closed cell fabric, but may be made of any other suitable material including flexible material, flexible plastic, heavy plastic, wood, or aluminum.

[0018] Housing 20 is preferably a truncated cone because it easily receives and snugly encloses a propeller and that can easily be carried, but all practical shapes are contemplated. The size and dimensions of the housing 20 can v...

Abstract

A boat propeller cover (10) has a housing (20) that surrounds the propeller while affixed to the propeller shaft, and provides a protective case for the propeller when it is removed from the shaft.

Description

FIELD OF THE INVENTION [0001] The field of the invention is boats. BACKGROUND OF THE INVENTION [0002] Substantially all boats have propellers. When a boat is not in use, the propellers can be either left on the boat or removed and stored separately. In both these instances, the propellers need to be protected for at least two reasons. First, the propeller blades are sharp and may cut someone. Second, the propeller blades may become damaged if they are not protected when not in use. [0003] Additionally, propellers are often carried from place to place. One reason may be to have several different types and sizes of propellers to accommodate changing boating conditions. Because propellers that are being carried can be damaged, and the blades can cut people, a carrying case for boat propellers is needed that also provides a protection function. [0004] Three general types of boat propeller covers are known. The first type includes individual covers that fit over each of the blades of a p...
