Description

[Detailed explanation of the invention] This invention uses a horizontal bar attached to the upper end of the column.
The present invention relates to a jumping exercise device that performs reciprocating rotational motion so as to draw a fan-shaped or semicircular locus.

In general, this type of jumping exercise equipment is one in which the applicant jumps over a horizontal bar attached to a support that is attached to a rotating shaft and rotates with the rotating shaft, as if jumping rope. A similar application has already been filed earlier.

However, in the above method, the horizontal bar rotates so as to draw a circular trajectory, so it requires a large space to draw the circular trajectory of the horizontal bar, and also Even if the horizontal bar is rotated at a particularly high speed by the speed adjustment mechanism, the speed of the rotating horizontal bar is naturally limited.

In order to further improve the above-mentioned conventional jumping exercise equipment, this invention has been developed by changing the rotational movement of the horizontal rod from a circular trajectory to a reciprocating rotational movement that describes a fan-shaped or semicircular trajectory. The object of the present invention is to provide a jumping exercise device which solves the conventional drawbacks such as space problems and speed problems, and its configuration will be explained as follows with reference to the drawings.

This invention consists of a base plate 1, a disc 2 rotatably disposed on the base plate 1, an electric motor 3 disposed on the base plate 1, a speed reduction device 4 connected to the electric motor 3, and a disc 2 rotatably disposed on the base plate 1. A drive shaft 7 whose one end is supported by a bearing 5 on the side of the reduction gear 4 and the other end supported by a bearing 6 on the center side of the disk 2 so as to be rotated at a reduced speed by the reduction gear 4, and an arbitrary position of the drive shaft 7 A rotor 8 that can be fixed at the top of the disk 2 and rotates in pressure contact with the upper surface of the disk 2, a crank 9 provided horizontally on the center of the disk 2, and a bracket disposed on the base plate 1) 10 , the bracket 10
A pillar 11 stands upright and is rotatably disposed at the center of the pillar 11, a swinging lever 12 is provided horizontally at the lower end of the pillar 11, and both ends thereof are connected to the tip of the crank 9 and the tip of the swinging lever 12. It is formed of a connecting rod 13 that is pivotally connected, a horizontal rod 14 that is attached to the upper end of the support column 11 so as to be easily removed, and a switch 15 of the electric motor 3, and the horizontal rod 14 is reciprocated at an appropriate speed. This is a jumping exercise device characterized by a rotating motion.

In the above configuration, as shown in FIG. 2, the disc 2 has an upright portion 16 protruding from approximately the center of the base plate 1 and a rotation mechanism 17 provided on the upper surface of the upright portion 16, for example. The insertion part 18 of the disc 2 may be fitted into the upright part 16 so as to be rotatable, but any method may be used as long as it can be made rotatable.

Next, the configuration of each part of the speed reducer 4 to the bracket 1-10 may be configured as shown in FIGS. 1 and 2, but other methods may also be used as long as they can be made smaller without any problem. There isn't.

Further, the support 11 may be rotatably arranged by fitting its lower end into the upright portion 19 protruding from the upper surface of the bracket 10, but it may be arranged rotatably by other methods, for example, from the lower surface of the bracket 10. It is also possible to use an arbitrary method such as stopping.

Further, the horizontal bar 14 may be attached to an auxiliary metal fitting 20 which is detachably attached to the support column 11 with screws or the like so that it can be easily removed when a foot or the like is caught during a jump.

To explain the operating state of the jumping exercise device of this invention, first, the rotor 8 fixed to the drive shaft 7 is rotated by the rotation of the electric motor 3.
The disc 2 rotates by being in pressure contact with the upper surface of the disc 2, and then the electric motor 3 The rotational movement from the to the crank 9 is converted into a reciprocating rotational movement at the support 11, and the horizontal rod 14 makes a reciprocating rotational movement so as to draw a fan-shaped or semicircular locus.

As explained above, according to the jumping exercise device of this invention, the rotational motion from the electric motor reaches the column and changes into reciprocating rotational motion, so that the horizontal bar attached to the column has a fan-shaped or semicircular shape. Because it performs reciprocating rotational motion that draws a trajectory, it does not require a large space compared to conventional rotational motion that draws a circular trajectory, and can be used for east longitude even in extremely limited locations. By increasing the reciprocating speed of the horizontal bar, athletes will be required to perform jumping movements at extremely high speeds that are several times faster than they could with conventional rotational movements. It can be expected to have an excellent effect on developing jumping power, explosive power, agility, etc.
