Double-functional band member for dumbbell component and dumbbell component using the same

Abstract

The present invention provides a dual-functional strap fitting for dumbbell assembly comprising: a middle strap; a first fabric strap and a second fabric strap coupled respectively to the middle strap, each of the first fabric strap and the second fabric strap including a thickened end; two buckles each including a slot, wherein the two buckles are slidably positioned on the first fabric strap and the second fabric strap through the slots, respectively, and the width of the slot is less than the thickness of the thickened end; fastening means positioned on a surface of the first fabric strap, a surface of the second fabric strap and a surface of the middle strap; and a coupling device positioned in the middle of the middle strap. The dual-functional strap fitting for the dumbbell assembly according to the present invention combines the functions of a handle strap and a coupling strap. Consequently, the cost for the dumbbell assembly is reduced. Moreover, since there is no need to switch between the straps, the dumbbell assembly can be used with ease.
