Description

Especially it is used for the apparatus for descending for jumping off from instrument of gymnast

[technical field]

The present invention relates to a kind of apparatus for descending, especially for being jumped off from the instrument when gymnast, especially It is for the stable purpose jumped off.

[background technique]

There are resilient cushions to delay during gymnast practices on the instruments such as double rod or uneven bars or pommel horse Punching is fallen.

Additionally provide the apparatus for descending for gymnast, wherein purpose be realized when being jumped off from instrument it is stable It jumps off.

The major function of the apparatus for descending of these mat forms must lead to the case where falling due to malfunction Lower absorption impact, to ensure personnel safety, not as the antivibration pad with maximum height, cannot allow the body Grasp the stabilization of sportsman.

In fact, level of shock absorption must also be consolidated enough to realize satisfactory landing and complete in gymnast The landing moment jumped off after practice provides stability.

These resilient cushions have building enclosure at present, which includes the parallelepiped made of foam.

Different from the practice mat of the thickness with several centimetres, such cushion is very thick, and about 20 centimetres, and they Length change from 1 meter to several meters.Under any circumstance, their height all cannot be bigger.

For example, patent application US2013/086744 discloses a kind of anti-fall pad of height with 50 centimetres or bigger.This Kind anti-fall pad for it is outdoor and including the protective layer in lower part so as to protection setting in upper part it is thicker, can be swollen Swollen building enclosure, as the safeguard measure for preventing tearing and other punctures.The building enclosure is not inflated, including can The inflatable element (such as, such as liner) of mechanical compression and at least one air intake.

Therefore, when building enclosure lifts restrictions, expandable component is restored to its natural shape and air in environment pressure It is inhaled under power, to fill up the gap between expandable component.

This cushion does not have shock-absorbing function and stabilization function in gymnastic, only has security function.

Shell must have high mechanical strength and usually be made of coated fabric, and coated fabric has shell centainly Rigidity.Even if this is to guarantee that the cushion is still able to maintain substantially parallel hexahedral shape institute after many times pressing It is necessary.

When tissue carry out contest when or gymnastics during the Games, it is necessary to for sports buildings (usually without cushion) provide pad Son.

This comprehensive sports venue must be equipped for race according to various sub-items.

In the case where gymnastics, there are numerous sub-items for needing damping according to the present invention and stablizing pad.

In fact, when must be provided with stadiums it may first have to which the cushion is transported to memory block.It is rigid due to cushion Property, they are difficult to transport, and someone is needed to roll them as well as possible, are especially just more difficult when cushion is very long. , can be huger if cushion is shorter, it is not easy to pass through from door, and remove very heavy.

Since the volume can not be compressed, so the volume of transport is equal to the volume of cushion, this is just needed using very The vehicle of big volume.

Once cushion is loaded, the cushion is just transported to venue to be equipped, then must carry out opposite mistake Journey is come so that cushion to be carried out from vehicle.

Due to cost to it is following directly proportional:

Cost of labor, time cost and volume cost, the let alone arduousness of the task,

The volume of transport,

It is this to be equipped to that this is in fact very high.

In gymnastics field, it is known that cushion include airtight building enclosure, the building enclosure have welding edge and At least one compartment, each compartment include at least one valve using pressurized air.

In order to keep being provided with internal spacer portion between upper surface and lower surface for original-shape needed for practice Part.These connections ensure all to maintain constant thickness on the whole surface.

Therefore, these building enclosures allow to produce the cushion for only taking up very small volume in the deflated condition, this is convenient for artificial It transports and limits the volume of haulage vehicle.It carries more easy and reduces weight, it means that decrease Personnel amount needed for installing cushion.

It is installed very quickly by inflation (that is, by being blown into forced air at the scene).

The framework is also perfect for vaulting table practice, but is then become for instrument practice and safety pad It is more complicated.Although pressure is identical as pressure used in slim floor practice mat, for example, about 220mbar, this cushion It is too hard for falling.On the other hand, if by pressure reduction to about 120mbar, this cushion provides good damping Effect, but a large amount of energy can be discharged in impact, so that gymnast's rebound too is more and makes it difficult to realize stabilization Landing.

[summary of the invention]

Present invention aims at propose it is a kind of solve it is above-mentioned about reducing volume and weight, be difficult to carry, abundant damping, dimension The facility for the problem of holding original shape and meeting necessary damping standard.

According to a feature, apparatus for descending according to the present invention, especially for being jumped off from the instrument when gymnastics Sportsman is especially used for the purpose of stable landing, which is characterized in that it includes at least one first damping volume and at least One the second damping volume, wherein at least one volume in the two volumes is inflatable, wherein this at least two volume It is stacked, further includes the component for connecting these at least two volumes in the stowed position.

[Detailed description of the invention]

Damping device according to the present invention will be described now according to specific non-limiting embodiment, this is illustrative to retouch Stating is realized referring to the attached drawing being appended, and the attached drawing includes following figure:

- Fig. 1: the perspective view of the apparatus according to the invention,

The exploded view of device in-Fig. 2: Fig. 1,

The side view of device in-Fig. 3: Fig. 1,

- Fig. 4: the cross-sectional view of the device of different elements is respectively illustrated.

[specific embodiment]

Various to show the apparatus according to the invention, which includes at least one first damping volume 10 and at least one A second damping volume 12, the two are stacked, further include connecting these at least two volumes in stowed position Component 14.First volume is placed in below the second volume.

In this case, in an illustrated embodiment, the first damping volume 10 has height H1 and the second volume 12 With height H2, the total height of device is H.

In the case where the safety pad being applied under horizontal bar, height H1 is between 2cm and 15cm and H2 is in 5cm and 20cm Between, and total height be necessarily less than 25cm so as to be maintained at required standard in.

In all cases, each volume has uniform thickness to form flat surface, wherein determining each volume Face be parallel.

In an illustrated embodiment, the first damping volume 10 is a cystosepiment 16, it is possible to by going along with sb. to guard him for known type Structure 18 covers, as shown in the cross section of Fig. 4.The shape of the cystosepiment 16 is parallelepiped, monolithic, is had and landing area The matched size of size, these sizes limit completely.

Because foam is flexible, even if the first damping volume 10 still maintains after many times pressing Its parallelepiped shape.

The embodiment also according to shown in, the second damping volume 12 include inflatable building enclosure 20, the building enclosure 20 are provided at least one charge valve 22.For example, the blowing pressure is between 120mbar and 220mbar.

The inflatable building enclosure 20 includes connection spacer 24, these connection spacers 24 are inserted in internal volume In, between the bottom side of upper volume and the top side of bottom volume.These connection spacers 24 are sightless from the outside, and And connection spacer 24 is shown in the cross-sectional view in Fig. 4.

Therefore, the second damping volume 12 maintains its outer shape, usually parallelepiped, and the second damping volume Keep its original shape.Note that in the preferred embodiment shown, H2 is greater than H1.

If it is necessary, the damping corner fittings 24 positioned at corner, i.e. damping peripheral frame 26 can be provided, only make in Fig. 2 It is shown for option, properly to maintain angular shape and to ensure perfectly to keep.These corner fittings and frame can be by foams It is made.

Another alternative solution is related to the additional cushions in the form of clump weight being located in corner, for example, with knot is gone along with sb. to guard him The deformable piece of structure same nature, these additional cushions are thicker and are partially attached to the inflatable building enclosure Top.

These clump weights increase damping, not instead of for the damping of landing, for the damping of rebound, to make to spring back It can partly be absorbed by these clump weights.

Because the two damping volumes 10,12 be it is stacked, be provided with the component for connecting the two volumes 14, to maintain the product of monolithic, even if one after landing and in damping volume or the opposite shifting of another generation After dynamic.

This connecting component 14 advantageously multipair connection patch 28-1,28-2, a connection patch are connected to top position The bottom surface of damping volume in setting, and another connection patch is connected to the top surface of the damping volume in bottom position.These are right Patch can be equipped withSystem, the system include being located at this to the latch hook on a patch in patch and being somebody's turn to do To the retaining ring on another patch in patch.

Alternatively, the single building enclosure from the first damping volume can also be provided, fully or partly Fix the second damping volume.

In an illustrated embodiment the inflatable second damping volume 12 of top position therefore can be with the first foam Damping volume 10 separates.

During transport and installation, it is noted that the first damping volume 10 has constant thickness H1, still, since it is It is independent, so it can be easily rolled up.Under any circumstance, even if not being rolled-up, this cushion is also easy to carry, and And its lighter weight is convenient for this carrying.

Finally, considering height problem of interest, the thickness of the second damping volume is still limited, and very It is easy to roll and transport.

Inflatable second damping volume 14 is deflated, and can easily be carried, is especially rolled up After rising.

The sub-assembly can also be kept as former state, because once deflating, the first damping volume and the second damping through connecting Volume has small combination thickness jointly.In fact, being empty inside inflatable building enclosure, and its nominal thickness is very It is small.

This is also undeniable technological merit.

As confirmed below, landing comfort level and shock-absorption quality meets required standard.

It is the impact that 150mm weight is 20kg using diameter for the simple lower instrument cushion with stable landing Body is tested.

For such cushion, the height of fall of impact body is always 800mm.

The shock-testing must carry out at the normal place on cushion, i.e., as at undefined 8 positions:

In the every nook and cranny in four corners, at two side 25cm for limiting every nook and cranny, i.e. four points；And

In center, along center perpendicular bisector, away from 25 centimeters of center of the mat, i.e. four points.

Following table shows in terms of discharging for damping, vertical deformation and energy that obtained value meets standard, especially NF Standard EN 12503-1 and EN 12503-4.

It is apparent that meeting standard, and the value of the anti-fall pad of these values and the prior art is very different.
