Abstract

A balance board structure for recreation or exercising use comprises a roller-supported foot platform having the roller positively retained in a frame under the platform by a retention pin extending through the roller into guide channels formed in opposed longitudinal side members of the frame. In use, the roller is manipulated along the frame by a person standing on the foot platform and the pin prevents separation of the components, for example during transport, or when the user falls off of the foot platform.

Claims

1. A balance board structure comprising a foot platform, a tubular roller under the platform and roller retention means comprising an elongate pin extending loosely through the roller, the pin having opposite end portions extending from opposite ends of the roller, the opposite end portions of the pin being received in respective elongate guide channels formed on the foot platform.

2. The invention of claim 1 wherein the foot platform has a frame on an undersurface thereof defining a roller-receiving pocket, and wherein the guide channels are formed in opposed longitudinal side members of the frame.

3. The invention of claim 2 wherein one of said longitudinal side members of the frame includes a pin-insertion and removal opening formed therethrough.

4. The invention of claim 2 wherein the pin is of a resilient construction enabling flexing thereof for insertion and removal of the pin into and from said channels.

5. The invention of claim 4 wherein the pin has cranked ends.

6. The invention of claim 2 wherein the foot platform is molded in plastic and the frame is integrally molded therewith.

7. The invention of claim 1 wherein the foot platform is shaped to simulate a game-playing item such as a football, soccer ball, basketball and the like.

8. The invention of claim 1 wherein the foot platform is shaped to simulate a food item such as a hamburger, wiener and the like.

9. A frame assembly for the undersurface of a board and the like to form a roller-supported balance board structure, the frame assembly comprising side frame members end frame members defining a roller pocket, a hollow tubular roller received in the roller pocket, and a retention pin extending loosely through the roller, the pin having end portions extending from opposite ends of the roller, said portions being received in elongate guide channels formed in the side frame members for guiding the roller along said side frame members while retaining the roller in the pocket.

10. The invention of claim 9 wherein one of said side frame members includes an opening for insertion and removal of the pin.

11. The invention of claim 9 wherein the pin is of a resilient construction for flexing into and out of engagement with said channels.
