The present invention relates to a fluid flow actuated tool.
Conventional tools, such as brushes, are difficult for a user to grasp, particularly for people who have arthritis and elderly people who do not have the hand strength to hold and operate such tools. This disadvantageously allows a user to improperly use the tool such that the tool does not adequately perform its function, such as using a brush to clean a rim of a tire or using the brush to wash dishes. Further, such tools are manually operated by the user, which requires great effort on the part of the user.
The present invention relates to a fluid flow actuated tool that can be easily grasped by a user such that the user can operate the tool in an efficient manner. As the tool is actuated by fluid, minimal effort is exerted by the user in operating the tool. The tool is lightweight and can be held by a single hand of the user, which makes the tool easy to maneuver and manipulate when operating the tool.
According to the present invention, the fluid flow actuated tool comprises a housing, a tool and an actuating mechanism. The housing comprises a housing interior. The housing interior receives a flow of fluid. The actuating mechanism comprises a fluid (water) wheel structure. The water wheel structure is connected to the tool. At least a portion of the water wheel structure is arranged in the flow of fluid for rotating the water wheel structure. The tool is actuated based on rotation of the water wheel structure.
The actuating mechanism may be arranged in the housing interior.
The water wheel structure may comprise a plurality of fluid engaging structures. Each of the fluid engaging structures may comprise fluid engaging material. The fluid engaging material may comprise a plurality of fluid engaging conical portions for engaging the flow of fluid.
Each of the fluid engaging structures may comprise a first portion and a second portion extending in a radial direction with respect to a longitudinal axis of the water wheel structure. Each of the fluid engaging structures may further comprise a third portion and a fourth portion extending in an axial direction with respect to the longitudinal axis of the water wheel structure. The first portion may be parallel to the second portion. The third portion may be parallel to the fourth portion.
The tool may comprise a tool shaft. The housing may comprise a tool shaft receiving opening. At least a portion of the tool shaft may be arranged in the tool shaft receiving opening.
