Adjustable Dumbbells
The magnetically adjustable dumbbells which enables installing additional weights magnetically and removing them easily using rotational motion. The advantage of using rotational motion for detaching the additional weights from the Adjustable Dumbbells. In this method, the linkage between the additional weights and the Adjustable Dumbbells may be strong and safe while the releasing of the additional weights from the dumbbell may be easy and may not require usage of great force.
This invention provides a device comprising a base dumbbell. The base dumbbell may comprise at least one magnet chip within a surface to which an addable weight can be attached. The device may further comprise an addable weight which may be made of un-magnetizable material. The addable weight may comprise at least one magnetizable chip. When comprising more then one magnetizable chip, the magnetizable chips may be located over an imaginary circle in correspondence with a same amount of magnet chips within the attaching surface. The addable weight can be attached to the base dumbbell by coupling said magnetizable chip to said magnet chip. Rotation of said addable weight relatively to said surface may detach said magnetizable chip from said magnet chip using shearing force and may locate the magnet chip against the un-magnetizable material, and thus the addable weight may be released and removed easily from the base dumbbell. The rotation of said addable weight may be about a pivot located at the center of said surface. At least one addable weight may be arranged about said pivot, and preferably more then one. The perimeter of said addable weight may be jagged in order to facilitate easy gripping and rotating of said addable weight.
