Description

The invention relates to a leaf and a door that includes

  such a leaf, including a garage door.

  The leaf can be moved between a closed position, in which it is substantially vertical and closes a bay of a construction, and an open position, in which it is substantially horizontal, a person can pass through the bay from outside to inside the building or vice versa.

  In order for a person to pass through the bay without having to move the entire leaf, the latter is generally provided with a door hinged to a frame forming the perimeter of the leaf, by means of hinges.

  Such a leaf is described in DE 201 12 528. The frame of this leaf is formed of hollow sections, and the hinges of articulation of the gate are housed inside a jamb of the leaf.

  This structure has a number of advantages. On the one hand, the leaf is less cumbersome because the hinges do not protrude from the leaf, which is particularly important for storage and transport. On the other hand, the aesthetics of the door is improved because the hinges are not visible, especially from outside the building.

  However, the leaf described in DE 201 12 528 has drawbacks.

  First, no means of adjusting the position of the door relative to the frame is provided. However, in practice, when mounting the leaf and / or door, the gate is often offset from the frame, for example in height or width, a game existing between these two elements. As a result, the aesthetic appearance of the door is not optimal. In addition, a burglar can introduce a tool in this game to force the opening of the gate.

  Furthermore, fixing the hinges inside the profile forming the amount can be difficult. Indeed, this attachment is generally provided by a screw-nut system cooperating on the one hand with a first hole provided in a wall of the upright and secondly with a second hole provided in the hinge. However, during assembly, it is difficult to place the two holes facing one another while seeking to introduce the screw in said orifices. This is all the more difficult as the fixing zone, inside the upright, is not very accessible, and that the tolerances on the dimensions are relatively small.

  The invention aims to provide a door leaf with means for adjusting the ro position of the door relative to the frame that are simple, robust, and effective. According to a second objective, the invention aims to simplify the method of fixing the hinges inside the frame.

  According to a first aspect, the invention relates to a leaf for a door, of the type comprising a frame adapted to cooperate with a construction intended to receive the leaf, said frame comprising a hollow upright; - A door associated with the amount of said frame by means of at least one hinge so as to be pivotable relative to said amount between a closed position and an open position; wherein said hinge comprises a male part fixed by a first attachment device to the upright and a female part fixed by a second device for fastening to the door, an opening being arranged in the wall of the upright situated opposite the door so that the part the male of the hinge can be housed inside the upright, and that the female part of the hinge can partially protrude from said upright and pivot during the movement of the door between the closed position and the open position. According to a general definition of the invention, at least one fixing device incorporates means for adjusting the position of the door relative to the frame in at least one direction.

  For example, the first and second fixing devices each comprise a substantially flat tab integral with the hinge and intended to be fixed to the amount, respectively to the door.

  The adjustment means may comprise at least one orifice provided in the tab, and a fixing member intended to be introduced into said orifice and to be fixed to the post or the gate, said orifice having, in at least one given direction parallel to the tab, a dimension greater than the dimension of the fastener in said direction, so as to allow the adjustment of the position of the door relative to the frame in said direction.

  According to a first embodiment, the first and second fixing devices incorporate adjustment means, the orifice provided in the leg of the first device and the orifice provided in the leg of the second device being oblong in substantially orthogonal directions.

  The fixing member of the first fixing device comprises for example a threaded rod permanently fixed to the upright. The tab of the first device can be fixed on the outer side wall of the upright, the orifice provided in said tab being oblong in the vertical direction.

  According to another characteristic, the orifice provided in the lug of the first device can communicate with an oblong opening substantially perpendicular to said orifice.

  According to a second embodiment, the tab of the first fastening device is welded to the inner face of the upright.

  The orifice provided in the tab of the second device may have, in all directions parallel to the tab, a dimension greater than the corresponding dimension of the fastener and, for example, have substantially the shape of an ellipse.

  Furthermore, the amount of the frame may comprise a wing extending laterally to the door, said wing forming a stop defining the extreme open position of the door.

  Finally, according to a second aspect, the invention relates to a tilting door with ceiling and vertical clearance, comprising a frame intended to be fixed to the masonry of a construction, said frame comprising two substantially vertical uprights and a substantially horizontal upper cross member. and delimiting a bay, the door further comprising a leaf as previously described, the frame of said leaf being connected to the frame by a tilting device, so that the leaf can be moved between a closed position, in which it is substantially vertical and closes the bay, and an open position, in which it is substantially horizontal.

  The other features of the invention result from the following description of embodiments, description made with reference to the appended figures in which: FIG. 1 is a perspective view of the gate door according to the invention, showing the inside face Figure 2 is an elevational view of the outer face of the door of Figure 1; Figure 3 is an enlarged view of the detail A of Figure 1, according to a first embodiment, the gate being in the intermediate open position; FIG. 4 is a partial cross-sectional view of the door, along the line IV-IV of FIG. 1, and according to the first embodiment, with the door in the closed position; FIG. 5 is a view similar to FIG. Figure 4, the gate being in the open position (solid lines) and in two intermediate positions of opening (dashed); FIG. 6 is a view similar to that of FIG. 4, illustrating a second embodiment of the invention; Figure 7 is a view similar to that of Figure 3, illustrating the second embodiment of the invention.

  Reference is firstly made to FIGS. 1 and 2 which represent a tilting door 1, with erasure from the ceiling and vertical clearance, for example a garage door.

  A first direction D1 is defined, substantially vertical, with respect to which are used the terms longitudinal, height, inferior, superior.

  The door 1 comprises a frame 2, intended to be fixed to the masonry 10 of a construction, said frame 2 itself comprising two vertical uprights 3, 4 and a substantially horizontal upper cross-member 5 and a threshold bar 6, fixed to the ground, between the lower ends of the two uprights 3, 4.

  A second direction D2 is defined, substantially parallel to the cross members 5, 6, with respect to which the terms lateral, transverse, width, left, right, and a third direction D3 such that (D1, D2, D3) are used. an orthogonal reference. In the direction D3, the door 1 extends between an interior space I to the construction and an outer space E. The door 1 is also provided with two guide rails 7, 8, extending in the direction D3 from the transom 5 and each of the uprights 3, 4. The guide rails 7, 8 are intended to be fixed to the ceiling inside I of the construction.

  The door 1 defines a bay and further comprises a leaf 9, linked to the door 1 by a tilting device having side arms 10 and a mechanical system provided with wheels (not shown) adapted to cooperate with the guide rails 7 , 8.

  The leaf 9 is able to be displaced by tilting between a closed position in which it is substantially vertical and closes the bay (FIG. 2), and an open position in which it is substantially horizontal and parallel to the guide rails 7, 8, to near the ceiling. The door 1 comprises a balancing system and a lock a point 11 for allowing the locking of the leaf 9 in the closed position.

  For convenience, the following description is made in the case where the leaf 9 is in the closed position.

  The leaf 9 comprises a frame 12 adapted to cooperate with the fixed frame 2 of the door 1. The frame 12 of the leaf 9 comprises two vertical uprights, respectively left 13 and right 14, and two horizontal crosspieces, respectively greater than 15 and 16. The frame 12 consists of hollow metal sections of substantially rectangular closed section.

  The leaf 9 further comprises a panel 17 connected to the frame 12. The panel 17 extends vertically between the upper cross member 15 and the lower cross member 16 of the frame 12, and from the upright 14 to the upright 13, about two-thirds the width of the leaf 9.

  According to other embodiments not shown, the panel 17 could be replaced by several adjacent panels by their longitudinal and / or lateral edges.

  The panel 17 is formed of a sheet which may comprise longitudinal stiffening zones formed by folding or profiling the sheet. Reinforcing elements 18 are fixed on the panel 17, transversely, and on the inner side I, so as to increase its resistance.

  In a variant, the panel 17 could comprise a generally flat inner wall and outer wall delimiting a space containing an insulating material. The presence of reinforcing elements 18 would then no longer be necessary.

  The leaf 9 also comprises a door 19 linked to the frame 12 and provided with a handle. The gate 19 extends vertically between the upper cross member 15 and the lower cross member 16 of the frame 12, and from the upright 13 to the panel 17. The door 19 comprises a frame 20 and, like the panel 17, a sheet may comprise longitudinal reinforcing zones, reinforcing elements 18 being fixed on the gate 19, the inner side I. The gate 19 could also comprise generally planar inner and outer walls delimiting a space containing an insulating material.

  The gate 19 is associated with the left upright 13 by means of two hinges 21, so as to be pivotable relative to the frame 12 about a substantially vertical axis 22, between a closed position, in which the door 19 is located substantially in the same plane as the panel 17, and an open position, in which the gate 19 extends outside the construction and is substantially orthogonal to the panel 17.

  A hinge 21 comprises on the one hand a male part 23 having a substantially flat tab 24 and a hinge 25. The male part 23 is housed inside the upright 13, its tab 24 being fixed to the wall 26 of the upright 13 next to the construction, that is to say the outer side wall.

  The hinge 21 further comprises a female portion 27 having a fastening portion 28 and a hollow cylindrical portion 29 adapted to cooperate with the hinge 25. The fastening portion 28 has the general shape of an L whose free end portion forms a tab 28a fixed to the gate 19, on the face of the gate 19 turned inward I. An opening 30 is provided in the wall 31 of the upright 13 located opposite the gate 19, and opposite the wall 26, in the This opening 30 allows the fastening portion 28 of the female part 27 to project out of the upright 13, towards the door 19, and to pivot about the axis 22 between the closed position and the position. open door 19.

  In the embodiment shown, the upright 13 comprises a flange 32 extending substantially parallel to the plane of the leaf 9 from the wall 31 of the upright 13 to the door 19, over substantially the entire height of the door 19. The flange 32 is arranged d one hand to cooperate with the gate 19 when the latter is in the closed position (Figure 4), and secondly to form a stop with the flat portion 28 of the female portion 27 of the hinge 21 when the gate is in position open (Figure 5). The wing 32 thus defines the extreme open position of the gate 19, which allows in particular not to risk hitting the building when opening the gate 19.

  Two modes of association of the hinges 21 with the leaf 9 are now described. A first mode is firstly described with reference to FIGS. 3 to 5.

  Two threaded rods 33, for example studs, are welded, at one of their ends, to the face of the wall 26 of the upright 13 facing the construction, inside said stud 13. Threaded rods 33 thus project inside the amount 13, substantially parallel to D2, but do not project outside the amount 13, between the frame 12 and the construction.

  Optionally, the threaded rod 33 may comprise a head and pass through an orifice provided in the wall 26, the head being located outside the upright 13. In this variant, the rod is also welded to the upright 13 and the head substantially flat. and very little thick, can not form a means of engagement for detaching the threaded rod from the upright 13.

  Thus, the door 1 has an improved resistance to burglary compared to the doors of the prior art, in which the head of the screw, located outside the amount of the building side, is accessible by a burglar who, by means of a suitable tool, can act on said head and remove the screw, thus forcing the opening of the gate.

  The tab 24 of the male part 23 of the hinge 21 has two oblong holes 34 in the vertical direction, of height greater than the diameter of the threaded rod 33. The dimension of the orifices 34 according to D3 is substantially equal to or slightly greater than the diameter of the threaded rod 33. Each of these orifices 34 communicates with an oblong opening 35 in the direction D3, so as to form two T-shaped holes lying in said tab 24.

  The attachment of the male part 23 of the hinge 21 to the upright 13 is carried out as follows: once the threaded rods 33 have been secured to the upright 13, the hinge 21 is inserted into the opening 30 of the upright 13 so as to insert the rods 33 into the orifices 34. The openings 35 allow to introduce and accommodate the hinge 21 in the upright 13 without the rods 33 form an obstacle to this movement. The tab 24 is then fixed by means of a washer 36 and a nut 37 (or a flange nut) to the wall 26 of the upright. This attachment can be temporary, the nut 37 can then be unscrewed to allow adjustment (see below), and then screwed.

  This assembly is particularly simple, because the threaded rods 33 are previously fixed to the upright 13, and there is therefore no need to seek to align an orifice of the hinge with a hole of the upright while introducing a fastener in these two orifices aligned.

  The tab 28a of the female part 27 of the hinge 21 comprises four orifices 38 oblong in the direction D2, these orifices 38 being here arranged at the corners of a rectangle whose sides are parallel to D1 and D2. The orifices 38 are intended to be placed facing holes 39 previously made, for example by drilling, in the gate 19. The orifices 38 have a greater width than the diameter of the holes 39, and a height substantially identical to or slightly greater than the diameter of the holes holes 39.

  The fixing of the female part 27 of the hinge 21 to the gate 19 is performed after the fixing of the male portion 23 to the amount 13. The orifices 38 of the hinge 21 are placed opposite the holes 39 of the door, then the tab 28a is fixed to the door 19 by means of screws 40. The diameter of the screws 40 is greater than the diameter of the holes 39, so that the screws 40 can be fixed effectively in the door 19.

  The adjustment of the relative position of the door 19 with respect to the frame 12 is possible on the one hand in the direction D1, thanks to the orifices 34 formed in the male part 23 of the hinge 21, and on the other hand in the direction D2, by the orifices 38 formed in the female portion 27 of the hinge 21. This adjustment is made at the factory, by vertical translation of the male part 23 relative to the amount 13 and / or by transverse translation of the female part 27 relative to the gate 19. The amplitude of these translations is limited by the dimensions of the orifices 34, 38 whose ends come into abutment end against the rods 33, respectively the screws 40. The attachment of the hinge 21 via the nuts 36 and the screws 40 actually intervenes only when the gate 19 is in the desired position relative to the frame 12. If necessary, a complementary adjustment can be made when mounting the door 1 in the construction. i0

  Alternatively, the tab 24 of the male part 23 of the hinge 21 may comprise a stud 50 projecting towards the wall 26, said stud 50 being provided to cooperate with said wall 26 when the gate 19 is positioned vertically in the desired manner by relative to the amount 13. The stud 50 makes it possible to maintain the nominal vertical adjustment of the door 19. If a subsequent change of this adjustment is necessary, the stud 50 can be cut, a vertical displacement of the male hinge then being possible again .

  The adjustment of the position of the door 19 with respect to the upright 13 is simple and effective, especially since the next setting D1 and the next setting D2 are dissociated.

  It should be noted that, for ease of understanding, a single nut 36 - washer 37 assembly has been shown in FIG. 3, and a screw 40 has been omitted.

  A second mode is now described with reference to FIGS. 6 and 7.

  The tab 24 of the male part 23 of the hinge 21 is welded to the wall 26 of the first upright 13 facing the construction, on the face of said inner wall 26 to the upright 13.

  This method of attachment is particularly simple, and has the advantage of not creating any element protruding outside the amount 13, between the construction and the frame 12.

  2867220 It But no adjustment of the relative position of the male portion 23 of the hinge 21 and the amount 13 is possible. The adjustment of the position of the gate 19 with respect to the frame 12, in the directions D1 and D2, is then integrally transferred to the female part 27 of the hinge 21.

  For this purpose, the tab 28a of the female part 27 of the hinge 21 comprises four orifices 41 whose contour is substantially elliptical in shape with axes parallel to D1 and D2. The orifices 41 are here arranged at the corners of a rectangle whose sides are parallel to D1 and D2. The lengths of the axes of the ellipse io are greater than the diameter of the holes 39 formed in the door 19. For fixing the female portion 27 of the hinge 21 to the door 19, the orifices 41 are placed opposite the holes 39 of the door then the tab 28a is fixed to the door 19 by means of screws 40.

  The adjustment of the relative position of the door 19 relative to the frame 12 is possible in the directions D1 and D2, by displacement of the female portion 27 of the hinge 21 in the plane of the door 19, the edges of the orifices 41 limiting the amplitude of this displacement. The adjustment is made at the factory and, if necessary, during the assembly of the door 1 in the construction. Once the desired adjustment has been obtained, the hinges are fixed to the door by tightening the screws 40 so as to avoid a subsequent displacement of the door 19 with respect to the hinges 21.

  For better understanding, one of the four screws 40 has not been shown in Figure 7. In addition, washers (not shown) may be provided to ensure improved attachment of the hinge 21 to the door 19.

  In both embodiments described, the dimensions of the orifices 34, 38, 41 are chosen to allow a sufficient adjustment amplitude.

  The mounting of the hinge 21 could be reversed, the male part then being fixed on the door 19 and the female part on the upright 13. In addition, in the case where the door 19 and the panel 17 each comprise an inner wall and a outer wall, the gate 19 could be articulated not to the frame 12 but to the panel 17, the hinge 21 then being housed inside the panel 17.
