Definitions

  • the invention relates to a door or a hatch with a corresponding stick frame which is suitable for mounting on housings for air-conditioning units, which allows access to the interior of these housings for inspection and maintenance, in particular for the purpose of inserting filters or other replaceable parts of the air-conditioning units is taking into account for the dimensioning also the modularity of the structure and/or the elements that make up the case, without the need for adjustment work, to allow assembly or replacement in a simple and quick way and an effective seal without to secure thermal bridges.
  • doors and hatches which are formed from an outer and an inner shell of sheet metal, connected to each other by bending the peripheral edges and forming a protruding multilayer peripheral flange which corresponds to the abutment on the stick frame, possibly provided with an elastic seal , whereby this is usually fastened in an opening on one of the modular elements which, for example, form the housing for air conditioning units.
  • a heat-insulating material is contained between said shells made of sheet metal, but since the outer shell is in direct contact with the inner one, there is a continuous temperature exchange between the outer environment and the inner space on the entire peripheral surface, moreover, the simple seal does not ensure one effective sealing and, due to the lack of an air chamber and a second seal, condensation often occurs in the area of the stop.
  • a door for air conditioners whereby neither the door leaf nor the door frame have thermal bridge interruptions, between the door leaf and the door frame there is a single seal which acts in the same way on the vertical and on the horizontal parts (threshold, lintel) of the door frame.
  • a door with these characteristics is subject to the formation of condensation on the leaf and the stick, especially in the peripheral area, close to the (only!) seal.
  • the horizontal floor elements have an identical Z-shaped cross-section, the door has a uniform cross-section along the entire perimeter.
  • the stop formed by the horizontal frame elements for the sole seal of the door has the same shape and dimensions as the corresponding stop on the vertical frame profiles.
  • Both horizontal stock profiles have a vertical mounting flange which, in the case of a modular construction of the housing, would prevent the exchange of a wall element with the door frame together with the door or the assembly of two door elements one above the other instead of two wall elements mounted one above the other.
  • a door with a door frame is known for residential construction, with either the door leaf or the door frame having aids to interrupt thermal bridges.
  • the door leaf has a specific cross-section in the threshold area and is equipped with two peripheral seals which are spaced among themselves while the door frame has a seal on both vertical elements and on the upper horizontal element (lintel) is on the lower extruded element (threshold) with several internal chambers a "seal" (sill seal 184) is provided which does not rest on any point of the door leaf, but represents a reduction in the cross-section of the metallic part of the sill.
  • the sill consists of an extruded profile with several chambers, it has a certain thickness which, together with the protruding part for the bearing of the door leaf seal and the considerable cross-section of the upper horizontal part (lintel) have the same cross-section as the vertical parts has considerably reduced the vertical free passage light.
  • the object of the invention is to create a door or a hatch of the above type for housings for air-conditioning units, whereby a maximum vertical clearance is ensured which almost corresponds to the maximum vertical height of the door or hatch, with a seal between the door leaf and the door frame and thermal insulation without thermal bridges between the outer part, which is normally exposed to environmental influences, and the inner part, which is exposed to the temperature and humidity conditions prevailing inside the housing, is ensured, thereby preventing the formation of condensation, especially in the area between the frame and the door leaf.
  • the invention proposes a door according to claim 1, which consists of an outer and an inner sheet metal shell, both of which have a peripheral edge bent by 90° which is attached to an intermediate plastic profile with several inner chambers, which acts as a thermal bridge interruption.
  • the space between said shells, which is easily accessible, can be filled with heat-insulating material.
  • Said plastic profile has a seat for the insertion of a first elastic seal and, in a spaced area therefrom, for a second elastic, e.g. extruded, seal, on.
  • the cross-section through the peripheral area of the door is therefore identical for the vertical and also for both horizontal sides.
  • the stick frame for the said door consists of two vertical parts, each of which consists of a metal composite profile with interposed plastic strips of the known type, for the purpose of breaking thermal bridges, between the outer part, which is exposed to environmental influences, and the inner part, which is exposed to temperature and is exposed to humidity conditions inside the housing and consists of two identical horizontal elements made of sheet metal bent in an L-shape or of an L-profile with a flat cross-section, the vertical flange on the side facing the housing interior serving as a stop for the first of the, am Door stop mounted all around, seals are used. Said horizontal elements are fixed at both ends by means of screws to the faces of the corresponding vertical composite profiles, which for this purpose are equipped with their own screwing seats with vertical axes.
  • the said Seal preferably has a tubular or mushroom-shaped cross section.
  • the seal When the door leaf is closed, the seal lies along one of the opposite sides on the bent flank of the inner shell of the door as a result of elastic deformation due to pressure load and, along the other side, on the area of the edge of the vertical composite profile facing the inside of the housing. on.
  • the two horizontal elements on the other hand, L-shaped in cross-section, the same first seal always rests, along one side, on the bent edge of the inner shell of the door leaf, while, with part of the surface facing the inside of the air-conditioning unit casing , rests against that stop which is formed by the vertical flange of the L-shaped bent or L-shaped cross-section profiles.
  • Said elements with an L-shaped cross-section can advantageously be made, for example, by bending a stainless steel sheet, without excluding the use of profiled or extruded elements made of different materials.
  • the wide part of the L-shaped profile can be narrower than the width of the vertical elements of the door frame or have longitudinal slots or recesses around the cross-section for heat transfer, especially in the rear outward area, beyond the contact area of the coextruded seal on the plastic profile connecting the two shells of the door leaf.
  • an element made of heat-insulating plastic can be provided in the area of attachment to the end face of the vertical elements, which occupies the area not covered by the flange of the L-shaped element.
  • the composite vertical profile of the frame has a wedge-shaped cross-section that reduces the free passage clearance towards the inside of the casing.
  • the fastening of the door jamb to the modular elements and/or to the structure of the air-conditioning unit housing is carried out using known fasteners, bearing in mind that, due to the flat section, the L-shaped horizontal elements require several attachment points, thereby giving these elements more dimensional stability to lend.
  • the 1 shows the outside view of a door according to the invention together with the corresponding door frame.
  • the 2 shows a horizontal section through the door leaf including the door frame according to 1 section plane II-II shown.
  • the 3 shows a vertical section through the door leaf including the door frame according to 1 Section plane III-III shown.
  • the 4 shows, as a horizontal section, the enlarged detail of the vertical edge of the door leaf and the corresponding door frame.
  • the figure 5 shows, in vertical section, the enlarged detail of the lower edge of the door leaf and the corresponding horizontal L-shaped element of the stick frame.
  • the door leaf 1 consists of an outer shell 1a and an inner shell 1c made of sheet metal which are connected in the peripheral area via a plastic profile 2, the space between said shells being filled with a heat-insulating material.
  • the shell 1a facing inwards of the housing for air conditioning units has a peripheral edge 1b which is angled at 90° and is anchored in a groove 2a of the plastic profile 2, e.g. by gluing.
  • the outer shell 1c also has a circumferential 90° angled edge 1d which is attached to the same plastic profile 2 by means of screws 3, this shell is therefore light. can also be dismantled later, e.g. to replace the heat-insulating material between the two shells.
  • the plastic profile 2 is of the extruded type with several internal chambers in order to ensure a high dimensional stability and to act as an interruption of the heat transfer between the two shells 1a, 1c subjected to different temperatures.
  • an elastic seal 4 In a groove 2b of the profile 2 is inserted an elastic seal 4, this is of the tubular type and abuts with one longitudinal side against the edge 1b of the inner shell 1a.
  • an extruded elastic seal 2c is provided, protruding in the direction of the door frame.
  • the seal 4 is also of the extruded type.
  • the door frame according to the invention consists of two vertical composite profiles 6 with elements 6a for the interruption of thermal bridges and two horizontal elements 8 with an L-shaped cross section which are fastened at the ends by means of screws 3 to the upper and lower faces of the vertical composite profiles 6 which are used for this Purpose are provided with screw-in seats 6d.
  • Said horizontal L-shaped elements 8 point to the side facing inwards of the housing for air-conditioning devices, a vertical flange 8a on which acts as a stop for the seal 4 of the door leaf 1, while on the side facing outwards, preferably in an area beyond the bearing of the seal 2c of the profile 2, the cross section through Breakthroughs or longitudinal slots 8b is reduced.
  • the vertical profiles 6 have a wedge-shaped cross section with the wider part directed towards the inside of the housing for air conditioners in order to, during the last part of the closing movement of the door 1, the elastic deformation of the seal 4 by compressive loading between the area close to the edge of the composite profiles 6 and the edge 1a of the inner shell.
  • the seal 4 is pressed with the front long side against the flange 8a of the horizontal L-shaped elements 8, which acts as a stop.
  • a sealed air chamber A is formed which is suitable for the insulating effect between that part exposed to the inside of the air-conditioning unit casing and that exposed to the eventual Is exposed to environmental influences to improve.
  • the elements forming the door leaf 1 and the corresponding door jamb can be made from inexpensive materials and can be processed using machines and devices that are very common.
  • the minimum extension in the vertical direction of the L-shaped elements 8 allows achieving a vertical free Passage light on the door frame, which is slightly smaller than the vertical extent of the door leaf.
  • the door or hatch is provided with hinges 5 with hinge pins 5a fixed 5b to one of the composite vertical profiles 6 of the door jamb; the door leaf 1 is equipped with at least one locking device 9 .
