Definitions

  • the invention relates to a rollable web for the thermal insulation of glass surfaces, in particular windows, the thermal insulation web consisting of a rollable blank which has a plurality of sections with tubular hollow chambers which are not connected to one another and are formed in the blank material.
  • reticulated foams are known which are modified in such a way that the cell walls are largely removed and only cell webs remain. Such reticulated foams are mainly used for sound absorption.
  • Foam plastics are lightweight materials with a cellular structure, whereby the cells can be closed, i.e. they form a closed cavity, or open, i.e. they are related to each other.
  • foam plastics with large or low deformation resistance are also known.
  • roller shutters In particular for the thermal insulation of glass surfaces, in particular windows, the use of roller shutters is known, which can consist of a wide variety of materials. In addition to specially designed fabric sheets, plastic rods are also used, which are connected to each other to form a rollable sheet. Roller shutters require guides for rolling up and unrolling and can therefore only be used to a limited extent, unless the glass surfaces to be provided with thermal insulation enable the arrangement of guide elements.
  • a roll-up web for thermal insulation of glass surfaces has already been proposed, which consists of a material web that is cut to the size required in each case.
  • the blank consists of a plurality of sections running transversely to the winding direction with hollow chambers formed in the material. This track can be used instead of the plastic rods forming the shutters.
  • the chambers cannot be reset (GB-A-1 142 934).
  • Another known solution for the replacement of roller shutters is to deploy a thermal insulation sheet in front of a window by means of a complex mechanical system. It is provided that large air chambers formed in the thermal insulation sheet are filled with air using air pumps or fans, so that insulating areas are formed. Unhindered circulation is possible in these insulating areas, so that heat exchange is prevented only to a limited extent (US Pat. No. 4,313,484), after a further development of this proposal an open single-chamber system with special ventilation slots is proposed, in which an even stronger circulation is permitted (US -PS 4 344 473).
  • the invention solves the problem of creating economical thermal insulation for glass surfaces, in particular windows, which can be rolled up in a small space and in which the thermal insulation is carried out with the aid of air cushions which can be formed automatically and are not interconnected and therefore prevent circulation within the thermal insulation path, without affecting the rolling up in a small space.
  • the invention provides a roll-up web for thermal insulation of glass surfaces, in particular windows, of the type mentioned, in which the walls delimiting the hollow chambers from a compressible and upon lifting of the roll-up pressure automatically into the predetermined, the full interior of the Starting position forming hollow chambers resiliently resiliently resetting and thereby forming the hollow chambers are made of plastic material, the hollow chambers extending transversely or longitudinally to the roll-up direction extending over the entire width or length of the thermal insulation sheet and being open at least on one end for connecting the interior spaces of the hollow chambers to the outside air.
  • a thin rollable sheet which has the character of a thin film with the possibility of being rolled up in the smallest space, but the design makes it possible to provide the material of the rollable sheet with a high level of thermal insulation that does not is solely due to the material, but is created by air cushions that automatically form the thermal insulation sheet, which is due to the special design according to the invention.
  • the thermal insulation property of the thermal insulation sheet is automatically produced when unrolling in that the channel-shaped or tubular cavities provided in the thermal insulation sheet are formed by automatic resetting of the walls delimiting the cavities, so that air is simultaneously sucked in during the formation of these cavities and into the interior of these hollow channels can penetrate, whereby a plurality of air cushions are formed in the thermal insulation sheet.
  • the air is pressed out of the cavities, so that the individual layers of the rolled-up sheet are sealed can lay against each other and thus has a rolled-up thermal insulation sheet of the smallest diameter.
  • the walls delimiting the individual hollow chambers automatically set up and form the air-absorbing cavities, this provision of the walls delimiting the hollow chambers being achieved by specifying the shape of the material from which the thermal insulation membrane is made or by additional devices, such as, for example, . B. by spring elements that are incorporated or molded in the plastic material of the thermal insulation sheet in the area of the wall boundaries delimiting or placed from the outside and consist of resilient and self-resetting material.
  • a spring element can consist, for example, of a leaf spring.
  • the automatic resilience for the formation of the cavities within the thermal insulation material takes place through the use of a corresponding plastic material, which has a high resilient elastic and resilience capacity. All those plastics can be used here that have the capacity to recover after removal of an external mechanical tension.
  • the hollow chambers formed in the thermal insulation membrane or in the material thereof are designed to be open on one side, so that the interior spaces of the hollow chambers communicate with the outside air, an inflow of outside air into the hollow chambers is ensured when they are formed. A certain suction effect is achieved when the wall surfaces delimiting the hollow chambers are installed.
  • the air-filled hollow chambers of the thermal insulation membrane represent cushions with high thermal insulation.
  • each hollow chamber section of the blank of the thermal insulation sheet consists of a number of tubular hollow chambers running parallel to one another and closely adjoining one another.
  • a plurality of adjoining tubular hollow chambers are formed over the entire length or width of the blank.
  • the wall surface delimiting each hollow chamber is molded into the plastic material of the thermal insulation sheet or resiliently elastic from the outside and is automatically reset from the extended position to a pre-bent position
  • Spring elements such as leaf springs or the like.
  • the thermal insulation sheet is fastened on one end to a winding core and carries a weight in the form of a rod or the like at its other free end.
  • the heat insulation sheet designated 100 in FIGS. 1 to 4 consists of a blank 10, which can be formed, for example, from two plastic films which are glued or welded to one another, but with the formation of hollow chambers 11 to 111, which are transverse or longitudinal to the winding direction X of the Thermal insulation sheet can run in the material of the thermal insulation sheet.
  • the hollow chambers 11 run transversely to the web winding direction X
  • the hollow chambers 111 run parallel to the winding direction X.
  • the material from which the thermal insulation sheet 100 is made is such that it can easily be rolled up around a winding core, so that the thermal insulation sheet 100 can be used like a roller shutter for windows.
  • the hollow chambers 11 extend over the entire width of the thermal insulation sheet 100 and are designed to be open at least on one end, so that the interior spaces of the hollow chambers 11 are in communication with the outside air when the thermal insulation sheet is unrolled.
  • outside air is sucked into the interior of the hollow chambers 11, at least on one end are open so that the interiors of the hollow chambers 11 with the outside air in Connect.
  • the thermal insulation sheet is attached at one end to a roll-up core indicated at 30 in FIG. 5, while the other free end of the thermal insulation sheet 100 has a weight in the form of a rod 35 or the like. carries, however, the weight of this rod 35 is dimensioned taking into account the total weight of the thermal insulation film so that in the unrolled state of the thermal insulation sheet no compression of the wall surfaces 15 delimiting the hollow chambers 11 is possible.
  • the weight 35 is only intended to compress the wall surfaces 15 delimiting the hollow chambers 11 when the thermal insulation sheet is rolled up in the roll-up area, so that the air can escape from the hollow chambers 11, so that the rolled up thermal insulation sheet can have the smallest diameter.
  • the arrows Y indicate the pressing together of the wall surfaces 15, 15a delimiting the hollow chambers 11, the roll-up direction being designated by X.
  • the wall surfaces 15, 15a straighten up automatically, i.e. they go back to the originally predetermined or preformed starting position, which is indicated at A in FIG. 5, which is indicated by the arrows Y1.
  • the wall surfaces 15, 15a delimiting the hollow chambers 11 then merge into the position shown at A when the web 100 is unrolled; during the erection of these wall surfaces, the air flows into the interior of the hollow chambers 11.
  • the hollow chambers 111 are also made, which run parallel to the roll-up direction X in the material of the thermal insulation sheet 100 or its blank ö10 (FIGS. 3 and 4). These hollow chambers 111 are also delimited by wall surfaces which have a resilience when an external pressure is released.
  • a hold-down plate is provided in the roll-up area, which is indicated at 135 in FIG. 5.
  • this hold-down plate 135 the support of the pressing together of the two wall surfaces 15, 15a of each hollow chamber 11 takes place during the rolling process.
  • spring elements 20 can also be used, which are indicated by dashed lines in FIG. 5.
  • Such spring elements which can also consist of a suitable plastic, but other materials can also be used, so that, for. B. the spring elements made of steel springs, in particular leaf springs, are either molded or fitted into the material of the thermal insulation sheet, in the region of the wall surfaces delimiting the hollow chambers 11, 111. Due to the resilient-elastic design of such spring elements 20, it is possible that they are pressed together during the reeling process, while due to their resilience the formation of air-absorbing cavities takes place.
  • the thermal insulation sheet does not need to consist of two foils laminated together, but it is also possible to use foils of corresponding size with a roll-up capacity, the hollow chambers 11 and 111 then being formed in the foil material.
  • the wall surfaces delimiting the hollow chambers, which are formed by the corresponding film sections, are then treated particularly thermally in order to achieve this straightening or resilience after the wall surfaces have been pressed together.
  • each section 12, 112 can be formed in the thermal insulation sheet 100, each of these sections then either having a single hollow chamber or a multiplicity of tubular hollow chambers running parallel to one another.
  • each section 12, 112 has a hollow chamber 11 or 111, the sections being arranged at intervals from one another.
  • sections 12 and 112, i.e. the hollow chambers 11 and 111 it is also possible to have sections 12 and 112, i.e. the hollow chambers 11 and 111 to be arranged close together, but it is. it is necessary that a narrowly dimensioned material web remains between two hollow chambers so that the roll-up ability of the thermal insulation sheet 100 is ensured.
  • each individual section 12 or 112 consists of a plurality of tubular cavities arranged side by side, high thermal insulation is achieved. These sections with a large number of channel-like or tubular cavities can also be pressed together, and because of the material used, a resilience is possible so that the cavities can be filled with air.
  • thermal insulation sheet 100 it is not necessary to use thin foils with a material resilience, but it is also possible to use thicker roll-up foils which consist of a suitable plastic, such as foam plastic, with a thermal insulation capacity, individual sections then being used in such a material Hollow chambers are formed.
  • a suitable plastic such as foam plastic
  • thermal insulation sheet 100 is used in the manner of a roller shutter in windows ensures a high level of thermal insulation, in particular when the thermal insulation sheet is in lateral guides is guided so that no cold air can penetrate between the insulation sheet and window surface.
