Description

[Technical field]

[0001] The present invention is applied in the technical field of sports equipment, and particularly refers to hand-held elastic exercise equipment. [Background technology]

[0002] Modern people are increasingly concerned about physical health, and as a result, many exercise machines have appeared, including handheld elastic exercise machines.

[0003] A conventional handheld elastic exercise device is, for example, Japanese Utility Model Registration No. 3139081. It discloses that an elastic bar is installed on each end of the handle, and fixed counterweights are installed on both ends of the elastic bar, so that the user can conveniently hold the handle and swing the elastic bar and counterweight, thereby achieving the desired effect.

[0004] The handheld elastic exercise device has a circular cross-sectional shape, which means that the center of gravity of the entire vertical direction is in the center, so it is easy to fall over when placed down, which is inconvenient and dangerous. At the same time, the elastic rod is also round, so there is no direction when the user swings it, which causes the elastic rods at both ends of the handle to swing in uneven directions, which causes the force received by both hands to be uneven. This not only reduces the effect of exercise, but also makes it easy to cause sports injuries.

[0005] In addition, different people have different strengths that they can bear, and the counterbalance effect that the counterweight creates is also different, while the conventional handheld elastic exercise equipment is fixedly limited by the counterweight installed, and it may not be possible to adjust it accordingly, which causes inconvenience in use, and even after a certain period of use, it is necessary to purchase exercise equipment with a different weight of counterweight, which increases the purchase cost and causes inconvenience in use. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] As shown in FIGS. 1 and 2, the handheld elastic exercise device of the present invention includes a handle 10, two elastic bars 20 and at least two counterweights 30.

[0017] Please also refer to Figures 3 and 5. The handle 10 has an elliptical cross section and is provided with a connecting hole 11 penetrating the inside. At least one protruding rib 12 is provided on the handle 10 along the vertical direction of the connecting hole 11, and as shown in the drawings, there are two protruding ribs 12, which protrude into the connecting hole 11 to form an equiangular shape. At least one positioning groove 13 is provided around each end of the handle 10 toward the connecting hole 11.

[0018] Please refer to Figures 3 and 6. The two elastic rods 20 each have a connecting portion 21 toward one end of the handle 10. A first section 22 and a second section 23 are formed to extend in sequence from the connecting portion 21. The connecting portion 21 has at least one slot 28 formed for the protruding rib 12 of the handle 10, and two slots 28 are provided as shown in the drawings. The connecting portion 21 also has at least one positioning ring 24 provided corresponding to the positioning groove 13 of the handle 10, so that the connecting portions 21 of the two elastic rods 20 can be inserted into the connecting holes 11 of the handle 10 and fixed. The slot 28 has a directional property, so that the protruding rib 12 of the handle 10 can be inserted and fixed, and at the same time, the positioning ring 24 of the two elastic rods 20 is fitted into the positioning grooves 13 at both ends of the handle 10. The cross sections of the first section 22 and the second section 23 are each formed in an ellipse, and the first section 22 gradually shrinks from the handle 10 toward the second section 23 to present an ellipse of the same proportion. In addition, a block 25 is formed to protrude from the end of the second stage 23 of each of the two elastic rods 20, and a number of positioning ring ribs 26 are installed at intervals between the second stage 23 and the block 25. As a result, a position limiting section 27 is formed between the two positioning ring ribs 26 of the second stage 23 and between the positioning ring rib 26 and the block 25, in which the cross-sectional area of ​​the first stage 22 is larger than that of the second stage 23.

[0019] Please refer to FIG. 4. The center of the counterweight 30 is provided with a through hole 31 so as to form an ellipse corresponding to the cross section of the second section 23 of the two elastic bars 20. The peripheral contour of the counterweight 30 is also provided with an ellipse that expands in the same proportion to the through hole 31, and a slit opening 32 is provided so as to cut along the long axis direction of the elliptical cut surface of the counterweight 30. The material of the counterweight 30 may be a thermoplastic elastomer (TPR). The slit opening 32 of the counterweight 30 can be widened during assembly, so that it can be easily fixed within the position limiting section 27 of the elastic bars 20. Thus, the user can fix the counterweight 30 to fit into the position limiting section 27 of the two elastic bars 20 according to needs.

[0020] Please refer to Figures 7 and 8 when using. The user can hold the handle 10 at a certain position, and the position of the palm is close to the short axis of the ellipse of the handle 10 and the fingers are directed to the long axis, which corresponds to the relative elliptical positions of the cut surfaces of the two elastic bars 20 in this embodiment. Therefore, the resonance direction that may occur when the user swings the handheld elastic exercise device has a directionality, and the problem of irregular throwing by the two elastic bars 20 is greatly reduced, and the exercise effect and safety in actual use can be effectively improved. Also, as shown in Figure 8, the user can change the position limiting section position of the two elastic bars 20 of each counterweight 30 according to the actual exercise needs.

[0021] In another method of use (not shown in the figure), multiple counterweights 30 can be installed corresponding to the positions of the position limiting sections 27 installed on the two elastic rods 20, respectively.
