3 results about "Dumbbell" patented technology

A dumbbell has an optional number of weight discs which stand on end in a stand, and a handle with anchorages. The anchorages and the weight discs have connecting structures which, in the axial direction, interconnect the anchorages with a neighboring weigh disc or neighboring weight discs, respectively. On the other hand, the connecting structures permit movement transversely of the axial direction. The weight discs display locking structures, which, in the activated state in directions transversely of the axial direction, prevent mutual movements between the weight discs and the anchorages. The locking structures have locking bodies which are movable so that their directions of movement have an axial component and which are disposed at the peripheral regions of the weight discs, and also are insertable in corresponding recesses in a neighboring weight disc or an anchorage. The locking bodies are operable by an operating arrangement located inside the peripheral contour of the weight discs.

The invention discloses a novel dumbbell convenient to carry. The novel dumbbell convenient to carry comprises a dumbbell power box. A fixed belt is movably connected with the outer surface of one side of the dumbbell power box. A gel paste is movably connected with the edge of the outer surface of the front end of the dumbbell power box. A palm stress belt is arranged below the gel paste. According to the novel dumbbell convenient to carry, a spiral spring, a protective sleeve and a guard plate are arranged, the spiral spring is used as a medium, and poundage of the dumbbell is adjusted by controlling the tightness of the spiral spring. The exercise method is efficient and simple, and the dumbbell has small size and occupies less space, the dumbbell is convenient to carry, and exercise can be carried out at anytime and anywhere. The dumbbell is especially suitable for workers who have no time to go to the gym to exercise for exercising. The a steel cable is sleeved by the protective sleeve, the arm is protected from being abraded by the steel cable. The guide plate can protect the lower arm of the dumbbell power box from being abraded. The guide plate is convenient to disassemble,clean and use, the functionality of the dumbbell is increased, and better prospects for use are brought.
