Description

When stationary Skip equipment are known springboard and trampoline.

For a playful-sporty locomotion in the form of jumps devices were accordingly 1.1 (Compression spring) and 1.2 (Rubber ball) developed. Also known from the patent literature pneumatic jumping equipment, the requirement that the center of gravity of the athlete should be on the longitudinal axis of the device, by lateral arrangement of the footrests and handle bars on the cylinder, bill (US 2003/0017917 A1, WO 99/61111 A1).

Either Rubber ball as well as compression spring variant have due to low jump height and width and because of their problematic handling no distribution found in recreational sports; They are commercially available as a children's game device.

The Previous pneumatic jumpers failed to succeed because the technical and application-related requirements as a whole received too little attention.

These Invention is the result of a holistic treatment of Objectives (easy handling, individual adaptability to users, individual customization on underground, low-wear Operation) and the resulting technical requirements and represents in the jumping device described below their engineering troubleshooting like follows:

• 1. The design of stroke and displacement based on the gas dynamics and setting a corresponding output pressure in the compression room leaves a size jump height to.
• 2. By due to the Fußrasten- and Griffholmanordnung given position of the athlete becomes an optimal center of gravity to control the device reached (on cylinder longitudinal axis).
• 3. A compensation piston in the piston rod provides jerk-free jumps for sure.
• 4. The footpegs are equipped with devices for fixing the feet.
• 5. A foot that moves in the old direction ensures a "full" resting position with an inclined landing or oblique Underground. Furthermore, the storage of the foot ensures torque-free Introduction of forces in the jumping device and thus protection of the guide elements.
• 6. An interchangeable sole of the plate foot allows for a quick adaptation to every underground.
• 7. As a pneumatic damper designed flange / piston pairings prevent or minimize noise and wear.
• 8. By simply setting the outlet pressures, the unit is fast on other body weights adjustable.

The under the points 1-4 illustrated technical features expand the previous use as a pure "hopping" device also on a gymnastic application (as with trampoline: somersault, screw, etc.) and allow a locomotion in the form of large jumps.

The ensure other technical innovations described above a low-wear Operation (long life of sealing and guiding elements), fast and easy adaptation to different users (weight, size), on different substrates (no prepared course required) and a noiseless Business.

The in hitherto described and built jumpers existing deficiencies and shortcomings are thus largely eliminated.

The technical concept and the application oriented execution of the vaulting enable its use as a sophisticated sports equipment, which also due to its ergonomic design of the average athlete to dominate is.

An embodiment of the invention will be described with reference to 2.1 and 2.2 explained.

It demonstrate:

2.1 Principle of the pneumatic jumping device

2.2 Pneumatic jumping device

Basic structure ( 2.1 )

The technical element on which the sports equipment is based is the gas spring. So it essentially consists of a cylinder 1 with sliding piston / piston rod unit therein 2 . 3 , A the cylinder 1 enclosing box carries the footpegs 6 and the handle bars 7 , The telescopic out of the cylinder 1 protruding piston rod 3 is supported at the lower end by a ball joint 9 on a plate foot 8th from.

The athlete standing on the footpegs the device shifts up and down by periodic jumping movements, whereby it lifts off from the ground at the first set-up, given correctly set pressures in the cylinder chambers.

Individual components ( 2.2 )

Cylinder unit:

The cylinder unit consists of cylinders 1.1 , from cylinder cover 1.2 and guide bush 1.6 ,

The sealing of the cylinder chamber to the outside through the arranged in the lid and socket O-rings 1.5 . 1.8 and 1.9 , On the cylinder cover are also a drain plug 1.3 and a valve 1.4 , The guide bush has a support ring in its lower annular groove 1.7 , and in the flange area is also a drain plug 1.10 arranged. Cylinder cover and guide bush are with the cylinder flanges 1.11 screwed.

Piston / piston rod unit:

The main components are pistons 2.1 , Piston rod 2.4 , Rod end 2.6 , Compensating piston 2.5 and plate foot 2.15 ,

The piston is screwed by means of fine thread on the piston rod and secured. In the upper annular groove of the piston there is a support ring 2.2 , in the bottom is an O-ring 2.3 arranged.

The support rings 2.2 in the piston and 1.7 in the guide bushing provide for the guidance of the piston rod unit in the cylinder.

In the lower end of the piston rod is the rod end 2.9 shrunk. The rod end is designed as a ball joint, in the lower part of a recessed below the ball contour valve 2.11 is arranged axially.

To the joint ball is by means of the two Pfannenringhälften 2.12 and the fixing screws 2.14 the plate foot 2.15 hinged. The base plate has an exchangeable sole ring on its sole 2.16 ,

The swivel range of the ball joint is through a rubber boot 2.10 covered. The rubber sleeve protects the ball joint against contamination and acts as a restoring device for the plate foot. The attachment to the piston rod end and the plate base is made by clamp bands (in 2.2 not shown).

The to reach the valve 2.11 in the pan 2.13 located opening can be closed by a lid (not shown)

In the piston rod is a free-flying compensating piston 2.5 arranged. In its upper and lower annular groove are the support rings 2.6 and 2.7 , who take his lead, in the 2nd ring groove from above an O-ring 2.8 for the sealing.

Support cassette unit:

The carrier box 3.1 is a sheet metal box in lightweight construction (weight savings by punching), which surrounds the pneumatic cylinder and is supported on the cylinder flanges.

The footrest carrier 3.3 are bolted to the carrier box. The footpegs 3.4 are by means of footrest bearings 3.5 rotatable on the Fußrastenachsen 3.12 stored. The rotation angle of the footpegs is limited by stops, and the restoring of the footpegs to the normal position is done by springs (stops and return mechanism in 2.2 not shown).

To fix the feet on the footrests they are with a shoe lock 3.6 provided, which works in conjunction with the correspondingly executed shoe soles according to the principle of a bayonet closure.

The handle bars 3.2 are by means of beam attachment 3.8 attached to the footrest carrier and can be adjusted in height. To facilitate the ascent to the sports equipment on a footrest carrier is a riser 3.7 intended.

Function:

The Device provides in unity with the athlete in the physical sense a mass / spring system where the elastic mass is the sum of the masses of athletes, Cylinder and carrier box unit is.

At appropriately set pressures in the individual cylinder chambers, the sports equipment with ascended athletes in the extended position, the compensation piston 2.5 is in its upper position, ie it touches the piston 2.1 ,

The application of a pulse to the footpegs by a jump movement compresses the gas in the cylinder (compression space, see 2.1 ).

at In the subsequent expansion, the device reaches its stretched position again and lifts off the ground.

By repeating this process, the energy introduced by the pulses adds up, leading to ever higher jumps. Theo Retically possible jump height is limited by the efficiency of the conversion E _kin / E _kompr / E _kin in the jumping _device and by the friction losses.

at Reaching the stretched position, i. at the moment of lifting the device off Ground is from the resting mass of the piston / piston rod unit applied a pulse opposite to the direction of movement of the system.

The compensating piston freely movable in the piston rod 2.5 should largely cancel the counter-impulse caused by the resting mass. For this purpose, the exact adjustment of the required pressure below the compensating piston is decisive.

As already mentioned above, the compensation piston in the extended position of the device, the piston 2.1 which is ensured by a slight overpressure in the space under the compensation piston in relation to the compression space.

When compression of the gas in the compression chamber as a result of the hopping movement, the compensation piston is moved when it exceeds the pressure below it down to be pushed back up during expansion. At the moment of his touch with the piston 2.1 a pulse is emitted in the direction of movement of the system, which corresponds due to its measurement interpretation in about the momentum of the piston rod unit and this largely compensated.

To avoid metallic contact between piston surfaces and flanges, these pairs of components are designed as pneumatic damping units (see 1.2 / 2.1 and 2.1 / 2.5 ). In the case bottom piston 2.1 and cylinder-side surface of the guide bush 1.6 a defined volume of air is locked when pumping the cylinder space by means of drain plug.

Establish the operational readiness:

For the transport is the jumping device reduced to the smallest dimensions (110 cm × 65 cm × 26 cm), i. the handle bars are disassembled and the piston / piston rod unit is completely inserted into the cylinder.

At the Construction, it is advisable to follow the sequence shown below; in terms of filling the gas rooms the order is mandatory.

1. Assembly of the handle bars and adjusting the height

2. pressurization the individual cylinder chambers.

For filling the vaulting can all non-aggressive, non-toxic and non-combustible gases used (observe regulations). Filling with air is the simplest Possibility, there except Air pump and manometer with adjustment no further equipment required are.

The pressure to be set in the compression chamber depends on the weight of the athlete. He should be so large that compression just because of the weight does not occur, ie the device with ascended athletes in the extended position remains. At a weight of the athlete of z. B. 82 kg and the resilient mass of the jump device of about 8 kg is to be set in the compression space absolute pressure 1.45 kp / cm ² . The pressure in the space under the compensating piston is to ensure that the compensation piston 2.5 on the piston 2.1 is about 10% above the pressure in the compression chamber, which corresponds to an absolute pressure of 1.5 kp / cm ² in this example.

2.1 filling the piston rod space under the compensation piston.

The drain plug 1.3 will be opened. After removing the protective cover of the opening of the pan 2.13 the adapter of the air pump hose is placed on the valve 2.11 plugged. After reaching the target pressure of 1.5 kp / cm ² (absolute), the hose is removed and closed the opening in the pan with the protective cover.

The compensation piston is now on the piston 2.1 at.

2.2 Filling the compression chamber

The drain plug 1.3 is closed, the drain plug 1.10 open. After attaching the adapter of the air pump hose to the valve 1.4 the compression chamber is inflated. The piston rod slides 2.5 out of the cylinder 1.1 ., and from the annulus under the piston 2.1 Air escapes through the loosened drain plug 1.10 , When the piston rod is extended so far that the distance underside of the piston 2.1 and cylinder-side surface of the guide bush 1.6 is still about 20 mm (by measuring the extension length of the piston rod notice), the drain plug is 1.10 closed. Now the inflation is continued until the target pressure of, for example, 1.45 kp / cm ² (absolute) is reached.

To Removing the hose, the jumping device is ready for use.

application

As at trampoline and springboard can be by adding the energy applied by the athlete reach jump heights that a sporty Enable game with gravity.

By the mobility the jumping device let yourself in addition to the turnerischen application (somersault, screw, etc.) as in Trampoline, develop a locomotion in the form of jumps.

The Experience with other fun sports equipment (BMX-bike, mountain-bike, Scate board, inline skaters, skis, etc.) have shown that after the market launch the devices independent develop individual application and usage directions.

Market expectations:

This jumping device with its extensive innovations represents an essential extension of the Funsportes dar.

One Success example in technical development and improvement an already existing sports equipment is the conventional one Roller skating. Its further development and transformation into an "inlinescater" have become a million times the distribution guided.

The annual Sales figures above exemplified sports equipment and apparatus leave for too the pneumatic jumping device a big Expect the market.
