Abstract

A jump appliance for helping player to jump more height or farther is composed of a T-shaped supporting handle, a diamond spring made up of elastic steel band by bending, whose one corner is connected to said handle, a horizontal pedal connected symmetrically to the joint point between handle and spring, and a rubber block installed to the bottom corner of diamond spring opposite to said joint point.

Description

Bouncer

(1) technical field:

The present invention relates to sports apparatus, but specifically a kind of can make the people jump high jump labour-saving bouncer far away.

(2) background technology:

People's spring is far away from kangaroo, because people's thigh is far away from the hind leg prosperity of kangaroo on the physiology, but the people just can improve spring greatly by the apparatus that can produce powerful elastic force, and for example human body just can be jumped very highly on trampoline.Trampoline is the entertainment body-building apparatus that people like, but its shortcoming is to need special place, can only be fixedly mounted on local a use, and bulky, and the price height is difficult for popularizing.

(3) summary of the invention:

The purpose of this invention is to provide a kind of bouncer, it can produce powerful elastic force, and human body can jump highly, jump far by this apparatus.

In order to achieve the above object, the technical scheme that the present invention takes is: this bouncer comprises upright T font handle support bar, it is characterized in that: the pole lower end is connected by on one jiao of top of the curved rhombus spring that is pressed into of elastic webbing steel, admittedly accompany one between pole bottom and the top, angle monosymmetric pedal laterally is installed, its diagonal angle end is fixed with a rubber cushion blocks.

Described rhombus spring can be one, also can be two overlapped in series on coaxial line, can also make oval-shaped, perhaps other geometry.

Advantage of the present invention is: 1, simple in structure, cost is low, making is easy; 2, small volume and less weight, energy and human body bound forward together, not occupied ground, do not used the place restriction, had the interest of entertainment body-building, be easy to penetration and promotion; 3, bigger ejection force is arranged, can make the people jump to such an extent that highly jump far, 3 meters of maximum heights, the instrument that can be used as leaping over obstacles (as across brook, bushes etc.) uses.

(4) description of drawings:

Fig. 1 is the overall structure schematic diagram of this bouncer list rhombus spring.

Fig. 2 is the structural representation of Double Diamond spring.

Fig. 3 is the structural representation of elliptic spring.

(5) specific embodiment:

Below in conjunction with accompanying drawing the present invention is described in further detail:

In Fig. 1, the 1st, handle, the 3rd, support bar connects into T shape, bilateral symmetry by bolt 2, the lower end is connected on by the curved rhombus spring 6 that is pressed into of the band steel of excellent spring one jiao, laterally accompany a pedal 5 between termination and the angle, bilateral symmetry is tightened up from center line with bolt and to be connected and fixed, on its diagonal angle end rubber cushion blocks 8 is housed, is connected and fixed by nail 7.

Fig. 2 is the structural representation of Double Diamond spring.As seen from the figure, it is to be formed by two identical rhombus springs 6,6 ' overlapped in series, connects into integral body by bolt 4 '.The purpose of design Double Diamond spring is the flexible distance of lengthening spring.

Fig. 3 is the structural representation of elliptic spring.This is the compression spring of another kind of version, curves two half elliptics by the elastic band steel, involutory back with bolt 9 connect elliptic spring, the perhaps directly curved ellipse that is pressed into.Certainly, the version of spring also is not limited to above-mentioned severally, also can adopt other geometry, to be preferably principle.

Kinetic energy when the elastic force of bouncer derives from the human body whereabouts, when human body landed, spring stress was compressed, energy is converted into elastic potential energy and is stored in the spring, pedal when jumping when both feet one, human body is pedaled the double action spring De Genggao of power and elastic force, thus reach jump high purpose of jumping far.

Human body can be done general jumping than usual by bouncer and jump to such an extent that highly jump far, realizes by energy accumulation how far the people can jump De Duogao actually, the performance that depends on spring: the flexible distance of spring is long more, stiffness factor is big more, and the energy of storage is just many more, also just human body can be played high more.But the selection of spring parameter should be corresponding with people's body weight, for this reason, according to people's all ages and classes, body weight, can design the product of different size.

Use and operation: during use, both hands are caught handle, and control crank maintenance barycentre steadiness, and both feet stand on the pedal simultaneously, bend one's legs earlier, one pedal with strength again, and human body just can taken bouncer one and indulge and rise.When landing, spring is subjected to the human body compression, and the kinetic energy of human body just is converted to the elastic potential energy of spring.Then both feet one are pedaled again, this moment human body because of the double action that is subjected to the power of pedaling and elastic force indulged higher, must be when landing once more to the bigger compression stress of spring generation, the elastic potential energy of spring thereby bigger.Continue like this, human body will jump over height more, up to the limit that reaches spring.

Claims

1, a kind of bouncer, comprise upright T font handle support bar, it is characterized in that: the pole lower end is connected by on one jiao of top of the curved rhombus spring that is pressed into of elastic webbing steel, admittedly accompany one between pole bottom and the top, angle monosymmetric pedal laterally is installed, its diagonal angle end is fixed with a rubber cushion blocks.

2, bouncer according to claim 1 is characterized in that: the rhombus spring can be one, also can be two overlapped in series on coaxial line, can also make oval-shaped, perhaps other geometry.
