Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] Fig. 1 is a perspective view of a cut section of a dumbbell made according to the first solution of the present invention, and Fig. 2 is a longitudinal sectional view of the dumbbell in Fig. 1 . Referring to Fig. 1 and Fig. 2, a cylinder 12 is also installed inside the elastic cover tire 11, and finally the dumbbell 10 shown in the figure is combined.

[0028] The main parts of the dumbbell 10 shown in Fig. 1 and Fig. 2 include an elastic casing 11 which is cut and sewed into a dumbbell shape through a flexible member; a cylinder 12 is inserted into the center of the casing 11 so that the user can grasp the dumbbell 10 and ensure that the contour of the casing keeps the dumbbell Shape; Iron powder 13 or sand 13 are filled in cover tire 11 insides.

[0029] Elastic cover tire 11 is mainly made of fiber, but its material is by no means limited to fiber. For ex...

Abstract

The present invention relates to an impact absorbing dumbbell and an impact absorbing barbell disk. The impact absorbing dumbbell includes an outer cover prepared by cutting a flexible member into a dumbbell and sewing the cut flexible member, thereby having a dumbbell shape, a cylindrical tubular body installed inside the middle portion of the outer cover for serving as a handle and keeping the dumbbell shape, and weight constituent powder charged in the outer cover. The impact absorbing barbell disk includes an outer cover prepared by cutting a flexible member into a barbell disk and sewing the cut flexible member, thereby having a barbell disk shape, weight constituent powder charged in the outer cover, and a bushing made of metal or synthetic resin, the bushing being inserted and fixed in the central shaft hole of the outer cover.

Description

technical field [0001] The present invention relates to a dumbbell and a barbell pan. After using the present invention, the above two kinds of sports equipment will all have a cushioning function. The present invention is a kind of elastic cover tire, and its appearance is divided into two kinds of dumbbell shape and barbell disc shape again, when using, sheaths on dumbbell and barbell disc respectively. The tread material of the elastic cover tire is mainly synthetic fiber, natural fiber or synthetic rubber; and its filling material is mainly weighted powder, such as iron powder or sand. In addition, the dumbbell and the barbell disc also include a circular tubular connecting part, which is mainly made of synthetic resin, foamed resin, sponge, EVA or other similar materials. If the exercise equipment is a dumbbell, this part is mounted on the outside or inside of it and acts as a handle when in use. If the sports equipment is a barbell, and the barbell tire is in the shape...
