Description

There has been air pump to want inflatable objects, particularly air cushion with part and pump injection section

This invention relates to a kind of object that will inflate, and it has the feature that the preamble in claim 1 provides.

A kind of like this object is known by DE-GM9308870, there for example pump gas partial design as the part of air cushion head.For with pump gas part be inflated part and separate necessary next door and in the process of pump gas, alternately protrude, because it alternately produces an excess pressure on this one side of next door or the another side to this one side or to another side.If partly compress at the beginning at pump gas, the next door bends towards inner, thereby has lost a part of volume of pump chamber, then before air is inflated part by the one-way exhaust valve inflow, must the next door outwards be protruded.

By the known a kind of hollow body of inflating of DE-OS2250154, bellows that are contained in hollow body inside have wherein been used.These bellows strengthen by porous wall, and this porous wall is connected bellows with the cover of hollow body.It is that elasticity by bellows self realizes that bellows erect after being compressed again again.That is to say that wind box must design more stablely.

Task of the present invention is, further improves the object that will inflate by the described type of preamble of claim 1, and the loss of pump chamber volume is reduced as much as possible.

The solution of this task is to be realized by the feature that provides in claim 1.

Abide by the present invention, pump gas partly is to separate by thin-walled and the part that will inflate, by the element that bears pulling force these walls is fixed on their home position, that is to say, and is outside by the tension connecting sheet, inner by horizontal contact pin and dunnage.Therefore the protrusion that replaces of thin-walled both sides is eliminated substantially, and like this, the volume of pump chamber can not lose.In addition, by pump gas partial design for independently whole to a certain extent, can accomplish to make the structure-irrelevant ground use separately of pump gas part and the object that will inflate.In addition, the cavity that is used to deposit pump gas material can keep very for a short time, can save pump gas material like this.

Other forms of implementation by the object of claim 1 are described in dependent claims.

If it then is favourable using the next door that is drilled with the hole transverse to horizontal contact pin and dunnage, this sets up a kind of connection of tension these next doors between thin-walled opposite one another, and thereby thin-walled is not outwards protruded.

Have the size identical with inlet hole at the hole that is drilled with on the next door in hole, like this, block pump gas material can reinstall in the cavity of depositing them by inlet hole with by these holes afterwards.

Regulation by relevant size design in the claim 4 can reach: can not manifest a kind of shape of depression in appearance for the object pump gas part of having inflated, because the wall that overcoat opposite each other is connected with each other will never be tightened when object is inflated too doughtily.

The embodiment who represents by an accompanying drawing explains this invention below.Wherein:

Fig. 1: by the cutting line B-B among Fig. 2 by being inflated object, the cross section by pump gas part particularly;

Fig. 2: press the cross section of cutting line A-A by pump gas part among Fig. 1;

Fig. 3 a: partial view that is drilled with the next door in hole;

Fig. 4: packing into is inflated the pump gas part view corresponding with Fig. 2 in the object.

The object that is inflated, people can be envisioned as air cushion with it, are made up of a pump gas part 2 and a part that is inflated 1.Overcoat 1a connects by the mutual tension of next door 1b ground.

It is that this pump gas part 2 has the basic shape of a rectangle in the zone of defining in plan view (Fig. 2) with next door 1b that pump gas part 2 is contained in one, and is to separate by air-locked thin-walled 3 and the part that is inflated.

Have one to be the one-way exhaust valve of diaphragm valve 9 on a thin-walled 3 therein, air can enter from pump gas part 2 by this diaphragm valve 9 and be inflated part 1 in form.

Along one with the consistent direction of diaphragm valve 9 directions, arranging the next door that is drilled with the hole 6 that two trends are parallel to each other, they be connected with overcoat 1a up and down, the side is connected with thin-walled 3 opposite each other, wherein, these connections must be non-hermetic.An air chamber has been defined being used to deposit between the cavity of pump gas material 11 in the next door 6 that is drilled with the hole, and it is connected with the part 1 that is inflated with ambient air and by diaphragm valve 9 by inlet hole 8.Pump gas material 11 is made up of the foamed plastics that becomes fragment, in this case, these foamed plastic block after air cushion is made by inlet hole 8 and hole 7 the depositing in the cavity of they of packing into.Variously can compress when being subjected to mechanical force, but the material that its volume can be expanded again when air enters can use as pump gas material.

Fixing the tension connecting sheet 4 that it moves towards inclination in the outside of thin-walled 3, the other end of these connecting sheets is fixed on the inboard of overcoat 1a.Basically stoped thin-walled 3 inwardly to subside by these tension connecting sheets 4.

Be drilled with a thin-walled 3 and one between the next door 6 in hole, horizontal contact pin 5 is arranged in being given for the cavity of depositing pump gas material 11, it is at thin-walled 3 and be drilled with the connection that has formed a stretch-proof between the next door 6 in hole.5 parts that occupy the cross section of this cavity of horizontal contact pin, so pump gas material can distribute equably.

Be extended with dunnage 10 between the next door 6 that is drilled with the hole, they are arranged above and below, and are on the plane different with horizontal contact pin 5.By dunnage 10 with by horizontal contact pin 5, be delivered in the pulling force that produces between the thin-walled 3.

Therefore thin-walled 3 is fixed on its home position at both direction by being subjected to draw piece.Wherein tension connecting sheet 4 also has the another one function, promptly at the part 1 that will inflate traction and vertical thin-walled 3 during by gas injection.This does not have great importance when especially filling pump gas material fully in storage chamber.

Hole 7 on the next door 6 that is drilled with the hole has identical substantially size with inlet hole 8.Done an advantage like this, that is, the pump gas material 11 of fritter just can and then be sent to storage chamber by hole 7 by inlet hole 8 under slight compression.These pump gas materials 11 expand again in storage chamber, and can no longer overflow by hole 7.Hole 7 therefore also must be enough big, to guarantee having enough air to enter by the next door 6 that is drilled with the hole along both direction all the time.

Thin-walled 3 and the next door 6 that is drilled with the hole should be designed in the size along their bearing of trends between the overcoat 1a: when air cushion was inflated, it is big that the ultimate range of the shell 1a of their aspect ratio in above-mentioned wall region is also wanted.Thereby can prevent that pump gas part from manifesting concave shape in appearance.

An aperture 12 is arranged on the thin-walled 3 in diaphragm valve 9 regions, and it makes from being inflated part 1 can have air circulation in a small amount to pump gas part 2.

Pump gas material 11 packed into, and this is to deposit the set cavity of this pump gas material can be undertaken by a filling pipe, and from then on pump gas material block extrudes in the filling pipe under situation by compression.

Pump gas material 11 can have the shape of bar blocks, and wherein, it moves towards vertical mutually and constitutes a stacking with very big free space layer by layer for these.Can cancel the next door that is drilled with the hole in this case, what exist on their position also can be with the opposed thin-walled 3 stretch-prooves interconnective horizontal contact pin in ground.

Thin-walled 3 can play a kind of contact pin of extending, for example a kind of contact pin of circle simultaneously between overcoat 1a in corresponding air cushion structure.Thin-walled 3 is tightened in completely charged air cushion forcefully in this case.

Be that example describes pump gas and the evacuation procedure of wanting inflatable objects in detail with an air cushion below:

Can be from following situation: in order to fold, as purpose, and air cushion is compressed together in order to transport, and among inlet hole 8 and the figure not giving vent to anger of expression close.

Air cushion is at first flattened, and people can open inlet hole 8 now, so air can enter the inner chamber of pump gas part 2 by this hole.Along with entering of air, pump gas material 11 volumes that are contained in the pump gas part 2 increase, and the air in pump gas part is filled to certain degree.For example the user meanwhile closes inlet hole 8 with pin with pin compressor pump gas part 2 now.At this moment air is compressed into the part 1 that will inflate by diaphragm valve 9.The process of this pump gas repeats repeatedly, till part 1 bulging that is inflated is when more bigger than desired final result.Close inlet hole 8 if end the pump air to open this moment, and then portion of air can be advanced pump gas part 2 by aperture 12 backflows, up to set up equal pressure in the locking system that is made of pump gas part 2 and the part 1 that is inflated.Air cushion has been ready to available at any time thus.

For the evacuation of air air cushion will be opened air outlet hole.Air cushion twists in together by from pump gas part 2 beginning the time then, and air not only is discharged from from pump gas part 2 but also from the part 1 that will inflate, and this moment, air flowed out by exhaust port.Air cushion is folded together and can betransported without difficulty in this state.Said process can restart.
