Description

The The invention relates to an insert for a wall opening.

closed Put rooms a shield against heat loss, Incidence of light and noise. The shielding is reduced by windows or glazed doors. Also a closed window is enough often not to shield the traffic noise on a busy street. The By curtains achievable darkening is not enough regularly out of a room even during the day to darken on summer days far enough for a restful sleep possible is. This is particularly unfavorable for the people, working at night and at the same time do not stay in the same place regularly can. Older windows and doors bad insulation, what above average Heating costs result.

One high level Darkening as well as additional Protection against noise and heat loss possible through the arrangement of shutters or hinged shutters. These must to the respective wall opening be adapted and are necessarily stationary, so not mobile. A takeaway and Use on or in another wall opening is not possible.

task The present invention is to provide an insert for a wall opening, which Protection against light, noise and / or heat loss. Preferably, the use of mobile and easily to the Size of each wall opening be customizable.

to solution the object is the use according to the invention for a wall opening, especially in connection with a window or a door, three-dimensional and inflatable trained. The three-dimensional, inflatable shape of the insert allows changeable External dimensions. The insert is inflated so far that it has a stable shape has, then in a wall opening or door opening made and subsequently continue to inflate until the wall opening Completely filled out is, or to circumferential side surfaces of the insert close to the insides of the wall opening issue. The air layer in use has a heat-insulating effect. The walls of the insert have heat-insulating, depending on the structure used, Soundproofing and / or lichtdämmende Properties.

The Walls of the insert are preferably elastically yielding to allow a better adaptation to the internal dimension of the wall opening. As wall materials are particularly suitable plastic, rubber or latex, as a film or fabric, coated or uncoated, single or multi-layered. Also can the materials are combined. The preferred form of the Insert corresponds to the shape of a box air mattress.

To Another idea of the invention is that the use a large front wall, a large back wall and narrow on the other hand and elongated sidewalls, Upper wall and bottom wall has and that sidewalls, top wall and bottom wall elastically yielding are formed as a front wall and rear wall. The property "elastic" refers to a reversible extensibility in the respective wall plane. in the Extreme cases are front wall and rear wall inelastic, while Side walls, Upper wall and bottom wall by their elasticity distinct bulges to adapt to the clear width of the respective wall opening can.

To Another idea of the invention are front wall and rear wall not only about the Side walls, Upper wall and bottom wall connected to each other, but also through connectors, which preferably in their longitudinal direction - perpendicular to the front wall and back wall - not are stretchy. As a result, front wall and rear wall have a defined area over the entire area Distance to each other. The existing during inflation of the insert Internal pressure then causes no greater distance from the front wall to back wall, but leads to a stronger one bulge of side surfaces, Top wall and bottom wall.

The adaptation of the size of the insert to the size of the wall opening is thus preferably carried out by stretching some or all walls of the insert. Alternatively or additionally, the size of the insert can also be changed by reversible folding of individual walls. In particular, it is provided in a further development of the invention that the front wall and rear wall are connected to each other via non-stretchable connecting pieces or non-stretchable walls and thus have a defined distance from each other at the edge, and that the front wall and rear wall are also connected to each other at the edge side walls, top wall and bottom wall, wherein the side walls, top wall and bottom wall perpendicular to the front wall and rear wall have larger dimensions than the marginal distance (after inflation) between the front wall and rear wall and that the side walls, top wall, bottom wall to compensate for said larger dimensions after the deployment of the insert outwards bulge. Side walls, top wall and bottom wall together form a circumferential, inflatable bead, which is supported against the wall opening inside. In this embodiment, all walls can not be made stretchable. A Execution with stretchable walls (also single stretchable walls) is possible.

To Another aspect of the invention is functional coatings provided at least in the area of the front wall or rear wall, wherein the functional coating, in particular heat-insulating, light-reflecting, have visible light absorbing and / or sound insulating properties can. In this case, a light-reflecting coating is preferred Outside on the back wall applied, as this one existing in the wall opening glazing (Window or door) the next lies. By choosing the functional coating are the desired Properties of the insert largely adjustable. For example allows a black formation of front wall and / or back wall one high degree of darkening. This can be further increased by a black one Coating of sidewalls, Top wall and bottom wall. Also edge can then no light through shine through the insert.

advantageously, are at least front wall or back wall multi-layered design. Thereby can even better insulation properties or multiple properties. Especially the noise insulation is dependent of the wall thickness and / or mass.

To In another aspect of the invention, the insert comprises means for temporary fixing of the rear wall at a window or door. So can on the back wall for example, suction cups or Velcro surfaces be provided. Possible is also a combination of suction cup and Velcro. The sucker adheres to the glazing and is attached to the back wall of the glazing with Velcro tape Insert connectable. The insert is thus secured in the wall opening. Even an unexpected pressure loss does not immediately lead to falling out the insert from the wall opening. In place of, or in addition to, the above means may also be provided other fixing means, such as for connection with the insides of the wall opening or with a window or door frame.

To In another aspect of the invention, the insert comprises at least a carrying device, in particular in the region of the front wall. Preferably If the carrying device is handles or carrying loops.

Preferably the insert has an inlet opening on, either on the type of known from air mattresses inlet opening or like a bicycle tube with integrated valve. About the inlet opening can the air will be drained again. In addition, a separate Exhaust valve may be provided to facilitate the discharge of the air or to accelerate. Without air content, the use is preferred foldable and therefore collapsible. In a typical application will be the insert clamped in a window opening during use and after use folded and stored under a bed or in a bed box.

To Another idea of the invention is an air conveyor or a compressor is provided, which preferably in the interior of the insert or on the front wall or outside of the insert is arranged, and which for the supply of air in the Use and / or for the removal of air from the insert is operable. When the compressor is it is preferably an electrically operated compressor, its own power source (batteries, batteries) or a mains connection having. Compressor according to the invention is any aggregate, can be conveyed with the air out of the insert or into the insert is.

To Another aspect of the invention are means for particular hanging Installation of the insert provided in a wall opening. It is the use provided for permanent or temporary retention in the wall opening. nevertheless The insert can be made removable. Preferably, a upper edge of the insert fixed to the adjacent wall opening or connected adjacent parts.

According to the invention of Use to be characterized by a concertina-like folding with particular transverse fold lines. Transverse means at a hanging or upright arrangement of the insert horizontally extending fold lines. By folding is a fast and reproducible contraction of the insert feasible. If necessary, the air escapes with active support the use. Subsequently The use takes up very little space.

To Another aspect of the invention, the use is characterized through management bodies for entry into suitable guides, especially in the wall opening. Preferably, the appropriate guide means in the area of the soffits arranged. Guided will be the movement of the insert when expanding or contracting.

Advantageously, the guide members are directed sideways. In hanging or upright arrangement of the insert, the guide members are thus horizontal, in particular directed outwards. The guide members engage, for example, in rails which are arranged laterally and upright as guide means in the wall opening. When Guiding members are provided in particular pins, rollers or a continuous rod.

According to the invention can as Management body the bottom of the insert may be arranged a rod, which protrudes on both sides. The supernatants are preferably guided in lateral rails in the window reveals.

Of the use according to the invention may be further characterized by a traction system, in particular Cable system for contracting the insert, especially in the direction parallel to the plane of the wall opening, preferably in the upward direction. With the traction system, for example, a lifting of the bottom the use in the direction of the top of the same and thus a compression of the insert possible. The existing in use air is discharged to the outside or even actively sucked by the compressor.

To Another idea of the invention, the Zugmittelsystem two lateral cables each lifting the underside of the insert. The cables are preferably laterally left and right on the insert, so in Area of soffits arranged. Also, the cables at the as a management body attacked rod attack and for example at the same time in the as a guide intended rails run. The cables are then through the guide means covered. The rails can inserted sunk in the side walls of the wall opening be.

As an electric motor preferably a stepper motor provided. Several stepper motors are preferably coupled with each other in terms of drive technology. Also can the motors (also the single motor) can be switched by limit switch be. The latter, for example, react to the position of the management bodies.

To Another idea of the invention may be a control unit for controlling the compressor and / or the drive for the traction system be provided. Particularly advantageous is a vote of the various Aggregates. So the compressor can suck air out of the insert, as soon as the traction system is activated to contract the insert is. In the reverse direction, air can be blown into the insert. In particular, will be additional Air blown into the insert after use by the traction system Completely was drained.

Of the Concept of the traction system also includes chains or belt drives or racks or the like. Important is the function of the System for targeted contraction or expansion of the insert.

advantageously, are controllable valves for faster venting and / or venting of the Insert provided. The valves can also be connected to the control unit be connected. So can to reduce the energy expenditure be provided that to expand the insert initially only Valves on the insert are kept open while the insert is alone due to gravity expands. Only after completion of this gravitational Extension, the valves are closed and the compressor promotes additional Air in the insert, so as to seal the wall opening through the insert as possible.

To the Constricting the insert then the valves are first opened again, then the Drive for the traction system activated and in addition can finally the Compressor controlled to evacuate the contracted insert become. In this case, not leading to the compressor valves are closed and valves between insert and compressor open.

To Another idea of the invention is in particular rigid connectors between front wall and rear wall provided the use. The connectors improve reproducibility the shape of the insert when contracting it. Also prevent the connectors are an enlargement of the Distance between front wall and rear wall of the insert, d. H. a departure from the box shape. The generated by the compressor Pressure in use should be as possible only on the surrounding walls (Side walls, Upper wall, lower wall) act, but not on front wall and rear wall. This improves the sealing of the wall opening. The connectors between Front wall and back wall have to not be 100% rigid. In particular, the connectors are not stretchable. Possible For example, connectors are made of textile material or not stretchable film.

According to the invention for front wall and back wall not be provided expandable material and in contrast for the side walls of the Use stretchy or foldable material. This is with Increasing internal pressure in use an even better seal the wall opening possible. By Inflating the insert or by releasing the air can be so in relation to for wall opening effective outer circumference to be regulated. After draining the air stops automatically reduced by the elastically stretchable material outer periphery one. The insert can then be raised and / or without the risk of damage be contracted.

It is first referred to 3 , An inventive use 10 has a substantially cuboid shape with one of an enclosure 11 enclosed volume. The volume is changeable by inflating the envelope 11 and by deflating the air.

The form of the insert 10 is adapted to wall openings for windows or doors, ie with large front wall 12 , large back wall 13 , narrow long side walls 14 . 15 , Upper wall 16 and bottom wall 17 ,

In the embodiment shown, the insert has a height H which is greater than the width B, and a relatively small thickness D, see 3 assigned coordinate system.

The serving 11 or the said walls 12 to 17 may consist of similar materials as the known bath-air mattresses, z. As PVC, laminated rubber material or other plastics or rubber-like substances. By inflating the wrapper 11 this is variable in height and width. At least the walls 14 to 17 bulge outwards. These bulges are not shown in the simplified representation of the invention reproducing figures, but may nevertheless be present.

4 shows an embodiment of the insert 10 with connecting webs 18 between front wall 12 and back wall 13 , The connecting bridges 18 are arranged here in several rows parallel to each other and extend from the front wall 12 inside the serving 11 to the back wall 13 and are made of a material that is not variable in length. This will keep the front wall 12 and back wall 13 while inflating the serving 11 a constant distance from each other. This supports the bulge only the walls 14 to 17 ,

According to 1 is in a wall opening 19 with fall 20 , Parapet 21 and soffits 22 . 23 a window is inserted whose frame with the numeral 24 is designated and its hidden by the use of glazing 25 outlined by dashed lines.

In the wall opening 19 In addition, the use is used 10 , but only inflated so far that it does not collapse. Accordingly, the bottom wall is located 17 on the parapet 21 on while the top wall 16 a clear distance to the fall 20 has, as well as the side walls 14 . 15 to the soffits 22 . 23 , The dimensions of the insert 10 are on the wall openings 19 roughly matched. In the example according to 1 extends the insert 10 over a slightly larger area than the glazing 25 , but is much smaller than the cross section of the wall opening 19 ,

When inflating take at least height and width of the insert 10 to. This can be achieved in at least two ways. According to the 1 and 2 is provided that the wrapping 11 or the walls 12 to 17 are elastically yielding in the respective wall level, so also front wall 12 and back wall 13 , In addition, connecting means between the front wall and rear wall according to the in 4 shown connecting webs 18 intended. This causes itself by inflating the insert 10 the form according to 2 results. The front wall 12 and back wall 13 stretch elastically. The inflation process is carried out until due to the elastic strain the walls 14 to 17 to fall 20 , Parapet 21 and soffits 22 . 23 issue. Likewise, outer edges of the front wall are sufficient 12 and back wall 13 up to fall 20 , Parapet 21 and soffits 22 . 23 , Exactly this is in 2 shown. The in 2 still recognizable narrow gap, for example between side wall 15 and soffit 23 is drawn only for illustrative reasons, but in practice does not exist.

The use 10 seals the wall opening 19 in addition to the window completely off and thereby causes additional thermal insulation, additional noise protection and next to a darkening. The properties mentioned can be controlled by targeted selection of the materials used and / or by suitable coatings of the envelope 11 or single walls 12 to 17 , For the purpose of obscuring, an opaque back wall is preferred 13 and / or front wall 12 , Sound and heat insulation are improved by the thickest possible material or a thick coating, such as a velvet coating or a neoprene-like wall. This is also opaque.

A somewhat different embodiment is based on the 6 and 7 explained. 6 shows another use 10 in the wall opening 19 and so far inflated that the use does not coincide. The picture is therefore correct 1 match.

The materials of the walls 12 to 17 in the embodiment of the 6 and 7 but are selected in a special way. front wall 12 and back wall 13 are not stretchable in the respective wall level, that is not or only very slightly yielding. This can be achieved by a textile layer or a non-stretchable film. At the same time connecting means between the walls 12 . 13 according to the in 4 shown connecting webs 18 intended.

side walls 14 . 15 , Upper wall 16 and bottom wall 17 are elastically very flexible. When inflating the insert 10 of the 6 . 7 keep front wall 12 and back wall 13 largely their dimensions, while sidewalls 14 . 15 , Upper wall 16 and bottom wall 17 bulge heavily until it attaches to fall 20 , Parapet 21 and soffits 22 . 23 , Again, therefore, the wall opening 19 because of the engagement 10 completely sealed.

The narrow circumferential gap between insert 10 and wall opening 19 is also in 7 provided solely for the sake of drawing. In practice, the walls should 14 to 17 by inflating the insert inside the wall opening 19 be pressed. This also applies to the corner areas.

Due to the inflation caused by the change in size of the insert 10 this can be used for different sized wall openings. The more elastic and flexible the materials used are, especially in the area of the walls 14 to 17 The higher the size differences can be between use 10 and the wall opening 19 be compensated.

For easier handling of the insert 10 can this according to 5 especially in the area of the front wall 12 Have holding devices. Shown is in 5 a handle 26 , Of these, for example, two side by side on the front wall 12 arranged, so the use 10 in incompletely inflated condition lightly into the wall opening 19 can be used or removed from this.

Advantageously, the insert 10 Means for fixing in the wall opening 19 on. In 5 are shown on the back wall 13 arranged suction cups 27 , These are arranged so that they touch the glazing 25 can be put on.

Additionally or alternatively, further holding means may be provided, such as a Velcro 28 for connection with a corresponding, on the window frame 24 or on the glazing 25 attached Velcro tape (not shown). Also, the suction cups can 27 via a Velcro connection with the insert 10 otherwise be connected.

In the embodiment of 5 has the front wall 12 near the bottom wall 17 a valve 29 on. This serves to fill the insert 10 with air and for venting. Additionally, a bleed valve, not shown, may be provided for faster venting.

In the area of the valve 29 is inside on the front wall 12 a compressor 30 arranged. This is thereby in the use 10 integrated. Conveniently, the compressor is electrically operated and has not shown connections and controls on. Also, a battery operation may be provided. With appropriate design of the valve 29 can the compressor 30 also for venting the insert 10 be used.

A mission 10 for a wall opening 19 also show the 8a to 8c , The special feature here is the fixed installation of the insert 10 in the construction of a building wall 31 ,

In the lintel 20 the wall opening 19 is a bottom open case 32 used, whose opening 33 flush with the lintel 20 concludes. The housing 32 is so large that it is the use 10 completely absorbed in the contracted state. In addition, in the case 32 the electric compressor 30 and drives 34 . 35 for cables 36 . 37 arranged.

The use 10 is accordion-like folded with transverse fold lines 38 on front wall 12 and back wall 13 , Through the fold lines 38 and the accordion-like structure may be the use 10 contract to a compact package and in the evacuated state in the housing 32 stay.

The use 10 is with his upper wall 16 in the case 32 held. On its bottom wall 17 is in use 10 a guide rod 39 incorporated laterally over the side walls 14 . 15 survives and parallel to the fold lines 38 is aligned. In the soffits 22 . 23 the wall opening 19 are upright guide rails 40 . 41 used in which the cables 36 . 37 run and where the guide rod 39 is guided end.

Based on an arrangement of the contracted use 10 in the case 32 Ventilation of the insert is performed by valves, not shown, and by activation of the drives 34 . 35 so that is the use 10 unfolds and the guide rod 39 in the rails 40 . 41 is moved down to rest on the parapet 21 , Preferably, at the latest at this time, the compressor 30 activated, so in use 10 an internal pressure is created, the side walls 14 . 15 to the soffits 22 . 23 presses and a good seal the wall opening 19 causes.

To support are front wall 12 and back wall 13 of the insert 10 connected by connectors, not shown, so that the internal pressure in the first place against the side walls 14 . 15 acts. Preferably, the latter are made of resilient material, as opposed to the non-compliant front wall 12 and back wall 13 , Alternatively, the side walls 14 . 15 be oversized in the direction of the thickness D, so that an internal pressure for bulging the side walls 14 . 15 leads, without having to be elastic.

compressor 30 and drives 34 . 35 are electrically operated and connected to a control unit, not shown, which is accessible to a user and individually operable.
