Description

  • The invention relates to a set of doors for closing a bay in a wall, comprising a first flexible door and a second door having a rigid lower edge, each of these doors being able to be subjected to an upward movement and a movement descending respectively between an open position and a closed position, the second door being arranged so that the lower edge moves away from the wall as it moves upwards to the open position by creating a slot between the wall and the lower edge of this second door.
  • Said second door is, for example, formed by a sectional door which consists of a succession of rigid sections articulated with respect to each other. When this second door is in its closed position, the sections and the lower edge of the door fits against the wall, while in the open position a slot is created between the portion of the wall above the door. bay and the lower edge of the door.
  • The currently known sets of doors have a relatively bulky and complex construction. Furthermore, these known sets of doors do not provide a tight seal when the flexible door is in the closed position and said second door is in the open position. In particular, spaces are present through which insects, a draft of air or dust can enter the enclosure closed by this set of doors. Thus, it is relatively complicated to make a set of doors that has a satisfactory seal.
  • The document US 2,501,454 describes a set of two doors which are each wound on a drum to allow their opening. Attempts have been made to seal the wall and all of these doors by mounting a housing above the bay in which said drums are enclosed. It is clear that the mounting of such a housing is relatively complex and it is not possible to use such a housing when one of these doors is not wrapped around a drum. This could, for example, be the case when the second door consists of a rigid door or a sectional door.
  • The document US 6,053,235 discloses a set of doors according to the preamble of claim 1 and 15.
  • One of the essential aims of the present invention is to present a set of doors with a relatively small bulk and a very simple construction. In addition, this set of doors provides a complete seal in a very effective and simple when one of the doors of this set is closed.
  • For this purpose, according to the invention, the flexible door is arranged at least partially between said second door and the aforementioned wall, this flexible door being able to move through said slot between its closed position and its open position when the second door is in the open position.
  • According to a particular embodiment of the set of doors, according to the invention, when said second door is in the open position while said flexible door is moved towards its closed position or towards its open position, this the last supports, when moving, against a guide surface provided to the wall above the bay and / or the lower edge of the second door.
  • According to a specific embodiment of the invention, the flexible door comprises a flap whose lateral edges are guided with respect to guiding paths passing through said slot between the wall and the lower edge of the second door.
  • Advantageously, when said second door is in the open position while said flexible door is in its closed position, the latter, on the one hand, is in contact with the wall above the bay in effecting a seal between this wall and the flexible door and, on the other hand, bears against the lower edge of the second door to maintain said contact and, therefore, to ensure the aforementioned seal.
  • In an interesting way, the guideways form a seal between the wall and said second door when the latter is in the closed position.
  • According to an interesting embodiment of the set of doors, according to the invention, the lower edge of the second door is provided with a guide surface for sliding the flexible shutter door on this edge during the upward movement or coming down the shutter.
  • Advantageously, the wall located above the bay is provided with a guide surface for sliding the flexible shutter door relative to this wall during the upward or downward movement of the flap.
  • According to a very interesting embodiment of the set of doors, according to the invention, the flexible shutter door is provided with a sealing element extending over substantially the entire width of the flexible door which, in the position closing the flexible door extends between the door and the wall above the bay by providing a seal between the wall and the door.
  • Interestingly, the flexible door is provided with a sealing member extending over substantially the entire width of the flexible door which, in the closed position of the flexible door, extends between this door and the door. lower edge of the second door, so that the flexible door is clamped between the wall and the lower edge.
  • Other details and particularities of the invention will emerge from the description given below, by way of nonlimiting example, of some particular embodiments of a set of doors, according to the invention, with reference to the drawings. attached.

    • The figure 18 is a schematic section of the set of doors of Figures 15 to 17 when the sectional door is in the open position and the flexible door is in the closed position.
    • The figure 19 is a section following line XIX-XIX of the figure 18 .
    • The figure 20 is a schematic section of a set of doors, according to the invention, comprising a tilting door and a flexible door.
  • In the different figures, the same reference numerals refer to the same elements or to similar elements.
  • In general, the present invention relates to a set of doors for closing a bay in a wall. This set of doors comprises a first flexible door and a second door which are arranged one behind the other in order to close the bay with one of these doors, when the other door is open.
  • The use of such a set of doors is particularly advantageous when said second door is formed by a rigid door whose movement between the closed position and the open position is relatively slow. If there is a passage of people or traffic with a relatively high frequency through this bay, the opening or closing of this rigid door causes a considerable loss of time when it is necessary to wait for the opening of this rigid door. The presence of a flexible door, which can be closed or opened at a high speed, overcomes this disadvantage. Thus, we put the rigid door in its open position when a passage with a relatively high frequency is expected and we put this door in the closed position during the night when no passage is expected.
  • The use of a flexible door has the additional advantage that such a door requires only a very limited space for mounting.
  • Advantageously, the flexible door comprises a flap whose side edges preferably cooperate with guide paths provided on either side of the bay, so that the bay can be closed by this flap. By the word "shutter", it is appropriate to understand, in the context of the present invention, any plane element of reduced thickness, at least partially flexible, flexible, possibly with one or more transverse stiffeners, such as a tarp , a lattice against mosquitoes or other insects, a plastic band, a cloth, a grid or a metal sheet, etc.
  • It should be noted, however, that a pronounced preference is given to flexible flaps formed, for example, by a tarpaulin.
  • Thus, the figures relate to a flap made of a tarpaulin whose lateral edges are, for example, provided with a bead or a succession of small rigid blocks articulated with respect to each other.
  • The Figures 1 to 3 represent a first embodiment of the set of doors, according to the invention, comprising a flexible door 1 and a rigid door 2 which can close a bay 3 in a wall 4.
  • The flexible door 1 comprises a flap 9 and two guide paths 5 and 6, extending on either side of the bay 3, in which the lateral edges 7 and 8 of the flap 9 are guided when the flap 9 is moved. between a closed position and an open position. At a level above the bay 3 is provided a drum 10 around which the flap 9 is wound during its movement to the open position or from which it is unwound during its movement to the closed position. Advantageously, drive means are provided for this purpose, not shown in the figures.
  • The guideways 5 and 6 are preferably mounted resiliently with respect to the wall 4, so that when the flap 9 is moved to the closed position, these guideways 5 and 6 are approximated. automatically to one another ensuring that the distance between them corresponds to the width of the flap 9. When the flexible door 1 is open and the flap 9 is, therefore, wound on the drum 10, the guideways 5 and 6 are moved back and away from each other automatically, as a result of their elastic assembly, so as not to be in the bay 3.
  • The rigid door 2, which is formed by a sectional door comprising a succession of sections 11 which are articulated with respect to each other, extends mainly along the flexible door 1 in such a way that the latter is arranged between, on the one hand, this rigid door 2 and, on the other hand, the bay 3 and the wall 4.
  • At the place where the sections 11 are hinged relative to each other rollers 12 are provided which are guided in guideways 13 and 14 corresponding. These guideways 13 and 14 extend substantially vertically on either side of the bay 3 and are curved at the location of the upper part of the bay 3, then extending transversely with respect to the wall 4.
  • The guideways 5 and 6 of the flexible door 1 are arranged between the guideways 13 and 14 of the rigid door 2 and the wall 4.
  • In this way, the guideways 5 and 6 of the flexible door 1 form a seal between the wall 4 and the rigid door 2 when the latter is in the closed position, as shown schematically in FIG. figure 2 . In particular, the lateral edges of the sections 11 are supported, in the closed position of the rigid door, against the guide tracks 5 and 6 of the flexible door 1, preferably by compressing these guide paths 5 a little and 6 which are made of a slightly elastic material.
  • When the flexible door 1 is in the open position, the lower edge 16 of the shutter 9 is above the bay 3 between the upper section 11 of the rigid door 2 and the wall 4 thus sealing between the rigid door and the wall 4 located above the bay 3. The lower edge 16 of the shutter 1 is, in particular, clamped between the wall 4 and the corresponding section 11 of the rigid door when the latter is in its closed position . For this reason, the lower edge 16 of the flap 1 preferably comprises an elastic bead extending along substantially the entire width of the flap 1.
  • When opening the rigid door 2, the lower edge 17 of this door deviates somewhat from the wall 4 so that the flap 9 of the flexible door can easily move through the slot 31 which is thus created. between the wall 4 and the lower edge 17 of the rigid door 2. This slot 31 is only present when the rigid door 2 is open and is not present when the door is closed.
  • When the rigid door 2 is in the open position and the flexible door 1 is in the closed position, it is important that the latter can close the bay 3 in a sealed manner. For this purpose, the part of the flap 1 extending at the location of the lower edge 17 of the rigid door, when the latter is in the open position, can bear against this lower edge 17. In this way, it is avoided that a space is formed between the flap 9 and the wall 4 above the bay 3. Such space could for example occur when, under the effect of a draft or a light pressure, the flap 9 is spaced from the wall 4 above the bay 3.
  • In order to ensure a permanent contact between the flap 9 and the wall 4 situated above the bay 3, when the flexible door is in the closed position, a guide surface is advantageously provided. on this wall 4 extending over substantially the entire width of the flap 1. This guiding surface is, for example, formed by a thickening 18 which is provided at the place above the bay 3 where the flap 1 comes into contact with the wall 4. Thus, this thickening ensures, on the one hand, a sliding with a minimum of friction of the shutter 9 when closing or opening the shutter and, on the other hand, the seal between the shutter 9 and the wall 4.
  • Similarly, a guiding surface can be provided on the lower edge 17 of the rigid door 2 in order to allow the flap 9 to slide on this lower edge 17 during the downward or upward movement of the flap 9.
  • The Figures 4 to 11 represent a second embodiment of the set of doors, according to the invention, with a conventional sectional door and a flexible door 1, in which the guideways 5 and 6 of the latter are fixed in the bay 3. This is illustrated in figures 6 , 7 and 8 .
  • The guideways 5 and 6 of the flexible door comprise, in particular, a profile having two parallel flanges bonded together in their longitudinal direction by a central crosspiece, this profile thus having an H-shaped section. The edges of a wings are bent towards the opposite edges of the other wing, so that two channels 19 and 20 are formed. In one of these channels 19, the corresponding edge 7 or 8 of the shutter 9 can move when closing or opening the flexible door 1, while in the other channel 20 is fixed a mounting strip 21.
  • This mounting strip 21 is fixed in the bay 3 on the wall 4. As shown in the figures, the mounting strip 21 is provided with lateral edges 22 and 23 having a thickness which is greater than that of the part of the strip 21 located between these edges 22 and 23. The mounting strip 21 is fixed at the location of an edge 23 on the wall in the bay 3 by means of a fastening slat 24 so that the mounting strip 21 is tightened. between the fastening slat 24 and the wall 4. The other edge 22 of the mounting strip 21 is held in the corresponding channel 20 of the aforementioned section.
  • The mounting strip 21 is made of a flexible material and, preferably, elastic, such as an elastomer, polypropylene or polyurethane. The above-mentioned section is preferably made of a relatively flexible, so that this profile can bend and twist somewhat and maintain a uniform tension of the flap.
  • When the flexible door 1 and the rigid door 2 are open, as shown in FIG. figure 8 , the mounting strip 21 is elongated so that it lies outside the bay 3.
  • During the closure of the flexible door 1 by the downward movement of the flap 9, whose width is smaller than the width of the bay 3, the profiles on both sides of the bay 3 are gradually approaching each other by fl ecting the corresponding mounting strips 21. This is illustrated in the figure 7 . Since the mounting strips 21 tend to lengthen, the flap 9 still remains substantially taut when it is in the closed position.
  • When the flexible door 1 is opened by the upward movement of the flap 9, the mounting strips 21 gradually assume their extended position, as shown in FIG. figure 8 .
  • When the flexible door 1 is open and the rigid door is in the closed position, as shown in FIG. figure 6 , the mounting strip 21 is bent and bears, with the aforementioned profile, against the surface of the sections 11 of the rigid door 2. The mounting strip 21 and this profile thus form a seal between the wall 4 and the rigid door 2.
  • The figures 5 and 10 represent the set of doors, according to the invention, with the rigid door in the open position and the flexible door in the closed position. The lower edge 17 of the rigid door 2 is provided with a guiding surface formed by a cylinder 25, possibly able to rotate about its axis, which extends along this lower edge 17 over a distance substantially corresponding to the width. In an interesting way, this cylinder 25 is formed by a succession of coaxial rollers. This guide surface allows the flap 9 to slide with a minimum of friction against the lower edge 17 of the rigid door 2 when moving the flap 9 to the closed position or the open position thereof.
  • In addition, the flap 9 rests against this guiding surface, or in particular against the cylinder 25, when it is closed, while avoiding that a space could be formed between the flap 9 and the part of the wall 4 located above the bay 3.
  • This part of the wall 4 situated above the bay 3 is also provided with a guiding surface formed by a cylinder 25 on which the flap 9 can slide during its displacement towards the closed or open position.
  • In order to ensure that a seal is made between the flap 9 and, on the one hand, the lower edge 17 of the rigid door 2 and, on the other hand, the wall 4 located above the bay 3 , the shutter 9 is provided with a sealing element 26. This sealing element 26 extends over substantially the entire width of the shutter 9 at the location of the latter opposite the lower edge 17 of the rigid door 2 when the latter is in its open position and the flexible door 1 is in the closed position.
  • Thus, this sealing element 26 is clamped between the lower edge 17 of the rigid door and the portion of the wall 4 above the bay 3 and in this way achieves the desired seal.
  • The sealing element 26 may be formed by a compressible flap 27, as shown very schematically in the figure 12 . This flap 27 is flattened when the flap 9 is wound on the drum 10 to open the bay 3 and is raised when the flap is unrolled from the drum 10 to its closed position.
  • In the figure 13 an alternative embodiment of the sealing member 26 is shown. The sealing element comprises, in particular, a bead 28 of an elastic material which is clamped between the wall and the lower edge of the second door when the latter is in the open position while the said flexible door is in its position. closing position.
  • In order to be able to move the shutter 9 in an upward and downward movement, driving means are provided comprising a gear 29 which cooperates with a rack 30 extending along the lateral edge of the flap 9, as shown very schematically in FIG. figure 7 . The toothed wheel 29 is located above the guideways 13 and 14 of the rigid door 2 and is controlled by an electric motor, not shown.
  • The guideways 5 and 6 of the flexible door 1 extend to the vicinity of this gear wheel 29. Since the width of the flap 9 is smaller than the distance between the guideways 5 and 6 through which the flap 9 is guided, these guideways 5 and 6 are somewhat twisted in the area between the bay 3 and the toothed wheel 29 when the flexible door 1 and the rigid door 2 are in their position opening. The lower part of the flap 9 and the lower edge 16 are always held in the guideways 5 and 6. This is shown schematically in the figures 11 and 14 . The figure 14 shows, in particular, the path of the guideways of the flexible door 1 by a line of dots and dashes, while the bay 3 is indicated by a dashed line.
  • When the flexible door 1 is opened, the shutter 1 can be wound around a drum or the shutter 9 can be extended above the horizontal part of the guideways 13 and 14 of the rigid door, as illustrated very schematically to Figures 4 to 11 .
  • In a very interesting way, the set of doors according to the invention can be made from an existing door having at least one rigid lower edge. For example, when a sectional door is provided in front of a bay, it is possible to mount a flexible door between this existing door and the wall. In particular, when the sectional door is subjected to an upward movement towards its open position, this sectional door deviates from the wall thus creating, in its open position, a slot between the wall above the bay and the bottom edge of the door. This slot is generally a width of the order of 1 to 4 cm.
  • The set of doors, according to the invention, is then produced by mounting two guide tracks for the flexible door on either side of the bay extending through said slot between the lower edge of the sectional door. and the part of the wall above the bay. A drum for winding a flap is, for example, fixed to the wall above the bay so that the flap can be moved through said slot between a closed position and an open position when the Sectional door is in the open position.
  • In this way a flexible door is mounted which cooperates with the sectional door by maintaining the original height of the passageway below the sectional door, when the latter is its open position.
  • In the Figures 15 to 19 such a set of doors is shown. As illustrated in Figures 15 and 16 when the sectional door 2 is in the closed position, it extends against the wall 4 around the bay 3 by sealing between this wall 4 and the sectional door 2. During the upward movement of the sectional door 2 to the open position, sections 11 of this door are gradually diverging from the wall 4. Thus, as explained above, a slot 31 is created between the wall 4 and the lower edge 17 in the open position of the sectional door, as shown in FIGS. figures 17 and 18 .
  • The flexible door 1, comprising a shutter 9 formed by a tarpaulin, is mounted between the sectional door 2 and the wall 4 so that the guideways 5 and 6 of the flexible door 1 extend through said slot 31. and during the upward or downward movement of the flap 9 between its closed position and its open position it is moved through the slot 31.
  • In the embodiment of the invention shown in Figures 15 to 19 , the guideways 5 and 6 of the flexible door 1 are mounted in a manner similar to that described for the Figures 4 to 11 .
  • When the sectional door 2 is in its closed position, the upper section 11 'of this door is slightly inclined with respect to the wall 4. Thus a space is formed between the wall 4 and this upper section 11' through which extend the guideways 5 and 6 of the flexible door 1.
  • At the upper edge 33 of the upper section 11 'a flexible seal 32 is provided extending along this section 11' between the latter and the wall 4 when the sectional door 2 is in its open position. When closing the sectional door 2, this seal is elastically deformed at the place where the guideways 5 and 6 of the flexible door 1 pass through the space between the wall 4 and the sectional door 2, as shown schematically in the figure 17 . In this way, a seal is obtained between the upper section 11 'of the sectional door 2 and the wall 4, notwithstanding that the guide tracks 5 and 6 of the flexible door 1 are arranged between this section 11' and the wall 4.
  • It is clear that it is not necessary that the upper section 11 'is inclined relative to the wall 4 in the closed position of the sectional door 2. It is possible, for example, to provide a cutout in this section. upper 11 'or in the wall 4 at the location of the guide tracks 5 and 6 of the flexible door 1 wherein are housed them when the sectional door 2 is in its closed position.
  • In that the slot 31 is used between the wall 4 and the lower edge 17 of the sectional door 2 as a guide for the flap 9 of the flexible door 1, the drive means, comprising a drum 10, for the flexible door 1 can to be mounted above the sectional door 2. In this way, the original height of the passage in the bay 3 below the sectional door 2 is not diminished by the mounting of a flexible door, according to the invention .
  • The figure 20 represents another embodiment of a set of doors, according to the invention. This set of doors comprises a flexible door 1 and a rigid door 2 constituted in particular by a conventional overhead door, for example, used to close a garage. When this rigid door 2 is closed, it adapts in a sealed manner to the wall 4 in the bay 3, while in the open position of this rigid door 2, as shown in FIG. figure 20 , a slot 31 is present between the rigid lower edge 17 of the latter and the portion of the wall 4 situated above the bay 3.
  • Guideways 5 and 6 are fixed in the bay 3 and extend through said slot 31. When the flap 9 of the flexible door 1 is moved between the open position and the closed position, it takes bearing against the lower edge 17 of the rigid door 2 and against the wall 4 above the bay 3. Thus, the flap 9 is guided through the slot 31.
  • In an alternative embodiment of the set of doors, according to the invention, there is provided a flexible sealing flap which is fixed along the rigid lower edge 17 of the second door 2. When the second door is in the open position, this flap seals the slot 31 between the rigid lower edge 17 and the wall 4. During the downward movement of the flap 9 of the flexible door 1 to its closed position, this flap is bent by the action of the lower edge 16 of the shutter 9, so that the latter is guided between the wall 4 and the flap.
  • When the second door is in the closed position, the flap seals between the lower edge 17 of this door and the floor.
  • It is understood that the invention is not limited to the embodiments described above and shown in the accompanying drawings, but that many other variants can be envisaged without departing from the scope of the present invention.
  • Thus, it is possible that the aforementioned section and the mounting strip 21 form a whole.
  • Although the described embodiments all relate to a set of doors with a first flexible door and a second door which is formed by a sectional door or a swing door, it is clear that this second door may be constituted by any door that is provided with a rigid or semi-rigid bottom edge. In particular, this second door could, for example, be formed by a flexible door with a rigid lower edge.
  • In some cases the guiding path 5 or 6 of the flexible door may be formed by a bead around which fits the corresponding lateral edge 7 or 8 of the flap 9.
