Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jumping surface made of flexible, non-stretch, taut fabric or the like, which is formed of an inflatable hose or tube and which extends below the jumping surface. The present invention relates to a jump rescue device or a lifesaving device having a jumping surface carried by a support mechanism arranged on.

In jump rescue devices of this general type known hitherto, the support mechanism acts like a spring, in other words like an element with an instantaneous spring-like realignment effect. This creates a trampoline-like effect that can cause injury to the person being rescued. Unfortunately, hitherto known devices do not eliminate such spring-like action.

This is because too little energy is consumed when a person jumps onto the device.

The aim of the invention is to eliminate the above-mentioned drawbacks. Additionally, energy must be expended when a person jumps onto the device of the invention;
This is achieved in such a way that the hopper is elastically soft, but not in a spring-like manner.

According to the invention, the support mechanism of the rescue device is formed by a framework or structure, around which extends a flexible jacket with a jumping surface, so that when someone jumps on top of the device, the support mechanism is It is elastically bendable and deformable,
The jacket can recover or return to its initial shape after the load on the device is removed, and the jacket further includes one or more air passage openings embodied as flow restriction means. It is provided.

What is important, therefore, is a support mechanism in the form of a framework or other similar structure that cooperates with a jacket extending around it, where the jacket has flow restrictions. Holes are drilled or otherwise provided with openings to form the means. This latter effect can be achieved, for example, by small holes or valves, or even by sections of breathable fabric or the like.

Advantageously, the dimensions of the support mechanism are such that in the active state of the rescue device it provides a slight and possibly elastic prestress on the jacket, thereby ensuring its rigidity.

In a device embodied in the manner of the invention, when a person to be rescued jumps onto the device, the support mechanism is deformed by collapsing, bending, or rolling the strut-like elements of the support mechanism; A certain amount of pressure increase then occurs within the envelope. However, this pressure cannot be increased arbitrarily. Rather, the pressure medium, in other words the air enclosed by the jacket, flows through the openings of the aforementioned restriction means such that extensive consumption of energy takes place.

The dimensions, design and arrangement of these passages must be determined with regard to the stiffness of the support mechanism, the size of the jump rescue device having to be taken into account, of course. Overall, the jump rescue device can have, for example, a parallel large monolithic shape or a cylindrical shape, but of course it can also have a polygonal or elliptical design. The operating height of the jumping surface is approximately 80 to 120 above the ground.
It can be on cm.

In order to ensure the rigidity of the envelope in the operating state of the device, and at the same time, a kind of centering effect occurs when the rescued person jumps onto the device, and this centering effect prevents the person from shifting to the side. Special features are provided for the support mechanism to ensure that it does not interfere. The elements of the support mechanism are
Advantageously, it must contact or act on the envelope at least in the area of the upper edge of the jump surface and possibly also near the bottom surface of the envelope. This can be accomplished with a closed frame formed to match the flat shape of the envelope. However, it is also possible for the support mechanism to be provided with a support member that conveniently extends to the upper corner of the envelope, especially perhaps at an angle such that the support member rises at a steep angle towards the outside when viewed from the center of the device. A support member may be provided to extend.

Following the rescue of a person, the device of the invention is readjusted and
and the support mechanism straightens to such an extent that the envelope is restored to its original shape, but only by forcing the atmosphere back into the interior of the envelope or in some other way. sell. The device according to the invention can therefore be easily standardized with a compressed air pump, by means of which the air under mechanical pressure is discharged in a limited manner and during the retraction movement of the mechanical part, the jacket is removed. A suction process that fills the space takes place.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to the drawings in detail, all the devices shown have an approximately square jumping surface 1, ie a surface on which the rescued person jumps. The jumping surface 1 is formed by the upper part of a jacket 2 extending around the entire device, which jacket 2 can be made of a very dense fabric, a thin non-stretch sheet, a rubberized fabric or a relatively stretchable fabric. Consists of non-flexible sheet-like products. The lateral edges of the jump surface l are considerably longer than the vertical line of the device, but these proportions are not essential. These ratios are also a function of the dimensions of the jump surface 1.

In the rest state, the rigidity of the jacket 2 is ensured by a support frame arranged within the jacket. Advantageously, this support frame does not consist of flexible air hoses or tubes, all of which communicate with each other so that they can be filled or inflated with a single compressed air connection 8. According to the embodiment of FIG. 1, the support frame has two closed frames 4 arranged close to the upper and lower peripheries of the device. The two frames 4 are connected to each other at the corners via cornered strut-like members 5. These strut-like members 5 are bent such that the knees of the bends point towards the center of the device.

A handle 6 can be provided near the upper rim of the device. Furthermore, the upper and lower peripheries, i.e. the edges of the jacket adjacent to the frame 4, can also be made non-stretching by a continuous cord (reference numeral 7).

The side walls 8 of the jacket are preferably provided with relatively small holes 9 located approximately in the central area of each side wall. These holes 9 form a flow restriction means for the air enclosed therein as it exits, but also form an inlet opening for the air when the device returns to the configuration shown in FIG. . The size of the hole 9 depends on the size of the device. Preferably, the holes are smaller than 1/100 of the associated side wall surface 8. to the extent possible,
And for reasons of symmetry, the holes 9 must be distributed evenly over the circumference of the device.

Rescue equipment is on site and the person being rescued is on jump surface 1.
Jumping onto it will result in an appropriate deformation of the device, with the strut-like member 5 collapsing or folding towards the center of the device and possibly deforming the upper frame of the support. At the same time, the pressure within the envelope 2 increases. However, high compression cannot be avoided. This is because air under pressure can escape through the holes 9, so that a considerable amount of energy is dissipated.

After the person has been rescued, the strut-like member 5 straightens somewhat, i.e. the support arranged in the envelope 2 attempts to resume the shape shown in FIG. 1, so that the displaced air It must be sucked in again through hole 9. Special equipment, such as non-return valves, can be provided to straighten the struts or to draw in air as quickly as possible, thereby bringing the device back into working condition as quickly as possible.

In the embodiment of FIG. 2, the upper corners of the jacket 2 are supported only by pneumatic supports 11. In the embodiment of FIG.

Therefore, continuous frames 4 disposed on the upper and lower peripheral edges of the outer cover 2 are no longer necessary. Only in the area of the bottom surface 12 a small frame 18 is provided, from which the horizontal support member 1
4 extends to the lower corner. Starting from the corners of the frame 13 are support members 11 that extend upwardly and outwardly at an angle.

To provide additional rigidity to the support member, the support member can be connected by a cross-shaped pneumatic piece located approximately halfway through the device.

In the embodiment of FIG. 8, the two frames 4 of FIG. 1 are again provided, but this time the frame elements are supported midway along their length by an inclined pneumatic support member 16. . The lower end of each support member 16 is disposed on the bottom surface of the device and is connected in air to a dome-shaped member 17.

In the embodiment shown in FIG.
It can be replaced by The shape of this restriction means is indicated by the reference numeral 18. The size of the mesh depends on the design of the device.

In the case of the embodiments of FIGS. 2 and 8, the same effects as described in connection with the embodiment of FIG. 1 result.

However, the device of FIG. 2 is relatively soft, while the embodiment of FIG. 8 is the most rigid of all the devices shown. Of course, the rigidity or flexibility of the device can be attributed to the shape of the struts or the support framework for the jacket 2.

Of course, the invention is in no way limited to the specific disclosure of the specification and drawings, but includes any variations within the scope of the claims.
