Description

[Detailed Description of the Invention] The present invention relates to an exercise equipment, and aims to provide an exercise equipment that can be easily assembled and disassembled and can be converted into various exercise equipment such as dumbbells and paddle bells.

An embodiment of the present invention will be described with reference to the drawings. In the drawing, 1 is a disc-shaped weight with a cavity 2 formed inside, and a connecting rod 5 with a spiral 4 carved therein is protruded from the center of the outer recessed part 3. Further, a connecting hole 8 having a spiral 6 carved therein and a tapered through hole 7 communicating with the cavity 2 is provided on the inside.

Note that 9 is a tapered cap that seals the through hole 7;
0 is a cushion band, and 11 is a kerf.

Reference numeral 12 denotes a grip tube connected to the weight, which has spirals 13 and 13 carved on both ends and reinforcing protrusions 14 and 13 inside.
Form...

Reference numeral 15 denotes a connecting device, and spirals 17 and 17 are carved inside on both sides of the partition plate 16.

In addition, 18 is a cylindrical roller tube whose inner diameter is slightly larger than the grip tube 12, and 19 is another exercise aid with a rubber band 20 attached, which is connected to the connecting rod 5 of the weight by a connecting tool 22 with a spiral 21 carved inside. The rubber band 20 is connected to the rubber band 20 and the end thereof is hung around the foot to perform a pulling motion.

The method of using the present invention is described below. The one shown in Figure 1 is used as dumbbell A, and two Kuwait 1
, 1.Fill the space 2 inside with water or sand, etc., and close the cap 9.
After fitting into the through hole 7, both ends of the grip tube 12 are connected to the connecting hole 8 and assembled.

If you want to make the dumbbell even heavier, you can connect other weights to the outside of the ways N and 1 of the dumbbell A.

The one shown in Figure 4 is used as barbell B.
Weights 1, 1 similar to the dumbbells are connected to the connecting tool 15.
Assemble by connecting it to the long grip tube.

The one shown in FIGS. 6 and 7 is used as a roller C, and the roller tube 18 is loosely fitted into a dumbbell (
(Fig. 6) or as shown in Fig. 6.
and connected by a grip tube 12 (FIG. 7).

In addition to the above-mentioned dumbbell A, barbell B, and roller C, it is possible to use the dumbbell A, barbell B, and roller C by appropriately changing the assembly method.

In the present invention, a hollow space 2 is provided inside, a connecting rod 5 in which a male spiral is carved is protruded from a recess 3 provided on the outside on the axis, and the connecting rod 5 is connected to the hollow space 2 on the opposite side of the connecting rod. A weight 1 provided with a connecting hole 8 having a female spiral that screws with the spiral of the connecting rod 5 or the connecting portion 13, a tapered cap 9 that seals the space, and a connecting rod 5 that connects with the connecting hole. A grip tube 12 is provided with connection parts 13 and 13 at both ends in which a male spiral of the same diameter is carved, and a connection part in which a female spiral is carved in both ends of the interior to be screwed together with the spiral of the connection rod 5 or the connection part 13. The weight 1, the grip tube 12, the roller tube 18
can be assembled as appropriate and converted into various exercise equipment such as dumbbells A, barbells B, rollers C, etc. In particular, the spiral of the connecting rod 5 and the spiral of the grip tube 12 have the same diameter, so the roller C can be assembled as appropriate.
When used as a water tank, the weights 1 can be connected and assembled facing each other, and the number of weights can be changed, the amount of water to be filled,
By changing the sand (different specific gravity), the weight of the exercise equipment can be adjusted.Furthermore, since the cap 9 and the through hole 7 are tapered, when screwing the grip tube 12 into the weight 1, the grip tube 12 The end of the weight can completely seal the through hole 7 by pushing in the cap 9, and in addition, since the inner wall of the weight is provided with a groove 11 toward the through hole 7, water and sand in the cavity 2 can be completely sealed. When taking it out, it can be completely drained, and when transporting it, if you disassemble each part and take out the filled water and sand, it has extremely practical effects such as being lightweight and not bulky.
