DOUBLE-FUNCTIONAL BAND MEMBER FOR DUMBBELL COMPONENT AND DUMBBELL COMPONENT USING THE SAME
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.
The present invention generally relates to a fitting for dumbbell, and more specifically, to a dual-functional strap fitting which can be used as a handle strap or a coupling strap and a dumbbell assembly equipped with same.
BACKGROUNDNowadays, a dumbbell with a handle strap has gained popularity in the market, in which the handle strap is connected to both ends of the handle of the dumbbell. A user, who tends to do any kinds of exercise, can hold the dumbbell handle with his hand being constrained by the handle strap so that the dumbbell is used at a safest condition.
In order to facilitate the disassembling and assembling of the handle strap from or onto the dumbbell and to provide additional functions, applicant of the present application filed CN patent applications, entitled “MULTIFUNCTIONAL DUMBBELL ASSEMBLY” on Dec. 8, 2005 (Application No. 200510111238.2; Publication No. CN1775333A) and on Jan. 27, 2006 (Application No. 200610023727.7; Publication No. CN1817389A), the entire contents of which are incorporated herein by reference as a part of the disclosure.
In the above patent applications, the two ends of the dumbbell, while maintaining at a status of not being taken off, are movable relative to the dumbbell handle. Therefore, a rapid disassembling and assembling of a handle strap or of an additional exercise member can be realized. However, a handle strap and a coupling strap for coupling to the additional exercise member, which serve different exercise purposes, are manufactured and used separately, thus resulting in a high cost. Moreover, a switch or changeover between the straps is required when the handle strap or the coupling strap is being used, which brings inconvenience to the user.
SUMMARYTo overcome the foregoing deficiencies, the present invention is aimed at providing a strap fitting which combines the function of a handle strap and a coupling strap such that the cost for the dumbbell assembly is reduced and the dumbbell assembly is easier to use.
To this end, a dual-functional strap fitting for dumbbell assembly is provided according to the present invention. The dual-functional strap fitting for dumbbell assembly comprises: 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.
A dumbbell assembly is also provided according to the present invention. The dumbbell assembly comprises: a handle; two ends which are movable relative to the handle; and a strap fitting removably coupled to the two ends of the dumbbell. The strap fitting comprises: 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.
The purposes, features and advantages of the present invention can become more readily appreciated by reference to the following description of the present invention, when taken in conjunction with the accompanying drawings.
As illustrated in
The first fabric strap 2 and the second fabric strap 3 are located respectively at two ends of the strap fitting 1 and are coupled to the middle soft strap 5. The middle soft strap 5 is made of a flexible and elastic material. The first fabric strap 2, the second fabric strap 3 and the middle soft strap 5 can be constituted by a long fabric strap covered with (by sewing or by bonding) a flexible and elastic material.
As illustrated in
Two buckles 4 can be slidably positioned at the first fabric strap 2 and the second fabric strap 3. Specifically, the first and the second fabric straps pass through the slot 41 on the buckle 4 and can slide through the slot freely. In other words, the buckles 4 can change their positions arbitrarily on the first fabric strap 2 and the second fabric strap 3 so that the length of the whole strap fitting 1 can be adjusted. As shown from the left side of
In addition, a coupling device is provided at the middle of the middle soft strap 5. The coupling device is a connector 6 in shape which is used to couple to the coupling strap of an additional exercise member.
As illustrated in
As illustrated in
Although the dual-functional strap fitting for dumbbell assembly is described in connection with two preferred embodiments, it is appreciated that variations and modifications can be made based on the above disclosure by an ordinary person skilled in the art. For instance, the nylon fastening tapes 7 for sticking the first fabric strap 2 and the second fabric strap 3 to the middle soft strap 5 can be replaced with a buckling member of other type such as buttons. The middle soft strap 5 can be in a non-soft form, for example, a “middle strap” can be formed directly by the fabric strap. Therefore, the scope of the present invention should be determined by the scope of the appended claims.
