Description

State of the art

From the Taiwanese Patent 375933 a multipurpose sports equipment is known, comprising an elastic rod, two movable handles, an elastic rope, two cable connectors, two conical sleeves and a footboard. The elastic rod is formed by a spring bar, which is connected at both ends with a threaded sleeve, which has an internal thread. The elastic rod is enclosed by a foam rubber sleeve. The two movable handles are made of metal with high specific weight and have at each end an external thread. The handles are each enclosed by a foam rubber sleeve. The elastic rope is formed by a tube of elastic material. The two cable connectors each have a larger opening and a smaller opening. The larger opening has an L-shaped threaded portion. In the smaller opening a metal mounting plate is arranged, which forms two inwardly extending spring leaves. On the outside of the smaller opening an annular groove is formed, in which an 8-shaped ring is arranged. The two conical sleeves each have a coarse thread at the larger end and a fine thread at the smaller end. In the fine thread a nut is arranged. The footboard has a board for the foot, a string on the underside of the board and a foot band on the top of the board. An external thread of the movable handle is screwed into the internal thread of the threaded sleeve of the elastic rod. The other external thread of the movable handle is screwed into the coarse thread of the conical sleeve. The L-shaped threaded portion of the cable connector is rotated in the nut in the fine thread of the conical sleeve. The end of the elastic cord is passed through the cable connector and fastened by the two spring leaves. The rope body is clamped by the 8-shaped ring. The other end of the elastic cord is passed through a footboard and attached to the other cable connector. The user can guide his foot through the footring and stand with his foot on the board. At the same time, the user grips the elastic rod with his hands and raises against the resistance of the elastic cord to the elastic rod, whereby the weight lifting can be practiced.

Although this versatile sports device has a variety of functions, its application is limited and dangerous.

The connection of the elastic rod is not reliable, whereby the elastic rod can be released during training, so that injury to the user or people in the area can be caused. The movable handles, which are made of metal with high specific gravity, the weight of the product is significantly increased, so that the product is not suitable for women and children.

For this reason, in view of the disadvantages of conventional solutions based on many years of experience in this field, the inventor has, after much study, numerous trials and continual improvements, developed the present invention.

The collars 53 each have a blocking part 531 , the support disk 42 can limit. The support disks 40 are at the two ends of the handle body 11 arranged. The support disks 40 each have a ring part 41 , around the opening 13 of the handle body 11 is placed, an extension part 42 that is different from the ring part 41 extends and into a support plate 32 a stand 30 can be plugged, and a lock hole 43 in which the collar 53 can be locked. The ring part 41 lies on one side on the outer flange 15 of the handle body 11 and on the other side of the protective cover 20 clamped, causing the support disk 40 is attached. The two support disks 40 attach the side connector 50 , The two ends of the elastic ropes K2 are with the side connectors 50 of two multifunction dumbbells 100 connected, whereby an expander is formed. The number of elastic ropes k2 can be changed to adjust the resistance of the elastic ropes k2.

In this embodiment, have the positioning holes 52 of the page connector 50 on the inner wall first recesses 54 in the first angular position a1 and on the front side positioning notches 55 in the second angular position a2. The elastic cables k2 each have a cable body K21 and fastening elements K22 at the two ends of the cable body K21. The fastening elements K22 each have a positioning projection K23 on the outside. The positioning projection K23 engages in the recess 54 in the first angular position a and is by turning in the positioning notch 55 positioned in the second angular position a2. This will make the elastic ropes k2 on the side connectors 50 attached. The way of connecting the page connector 50 and the elastic cord k2 is not limited thereto and can be arbitrarily selected by the manufacturer.

During assembly, first the two support disks 40 around the two openings 13 the weight grip 10 placed and thus lie on the outer flanges 15 at. Subsequently, the locking parts 531 of the page connector 50 through the support disks 40 guided and into the locking holes 43 slide. After that, the two protective covers 20 on the two openings 13 the weight grip 10 screwed. Finally, the positioning projections K23 at the two ends of the elastic cables K2 engage in the recesses 54 the positioning holes 52 one. By turning, the positioning projections K23 become the positioning notches 55 positioned. Therefore, an expander is formed.

11 shows the fourth embodiment of the multi-functional dumbbell according to the invention 100 , where the side connector 50 in the middle a positioning hole 52 having. The two ends of the elastic rope k2 are in the positioning holes 52 the side connector 50 of two weight handles 10 attached, whereby a resistance rope is formed. With the resistance rope, the user can make the stretching or rudder movement. The user can also stand on a weight grip and pull the other weight grip by hand.

The 12 to 14 show the fifth embodiment of the invention, which is still a stand 30 and two support disks 40 includes. The support disks 40 are identical as formed in the third embodiment. The stand 30 has a bottom plate 31 and two support plates 32 on. The support plates 32 stand close to the two ends of the bottom plate 31 , The support plates 32 each have a slot 321 , in the extension part 42 the support disk 40 can be plugged. The two support disks 40 be around the two openings 13 the weight grip 10 placed and thus lie on the outer flanges 15 at. Subsequently, the two protective covers 20 with the openings 13 screwed. Finally, the two support discs 40 in the plug-in slots 321 the support plates 32 of the stand 30 plugged. As a result, a push-up handle is formed.
