Description

Title of the invention: Shuttering system comprising at least one door and an improved locking mechanism

[0001] The invention relates to a closing system comprising at least one door, and more particularly to automatic sliding doors.

[0002] A door, sliding or swinging, is used to provide a separation between two spaces, and in particular a public space and an outdoor space, on either side of a wall provided with an opening. In particular, a sliding door can be mounted so as to be movable in translation in a sliding direction between an open position in which the sliding door allows passage through the opening and a closed position in which the sliding door prevents passage through the opening. Commonly, automatic sliding doors have a locking system comprising a espagnolette lock with a lower rod and / or an upper rod on one of the door leaves, and, in the locking position, the rod(s) are received in a hole made in the floor and / or the ceiling of the building in which the door is mounted.

[0003] However, such a locking system has many drawbacks.

[0004] Drilling must be carried out very precisely, as any drilling error can lead to difficulties in locking the door and necessary maintenance. Drilling can also damage the support in which it is carried out, for example tiles, stones or concrete, when installing the sealing system.

[0005] This locking system offers little resistance to breaking into the sliding door by inserting a crowbar between the two leaves to pry them apart.

[0006] There is therefore a need to propose a closure system comprising at least one door whose security is improved by increasing resistance to burglary, and whose installation is simplified and avoids damage to the support of the closure system. Summary

[0007] To this end, the present invention relates to a closure system comprising at least one door for closing an opening having a threshold, the door being intended to be mounted so as to be movable in translation in a sliding direction, or in rotation around an axis, between an open position in which said door allows passage through the opening and a closed position in which said door prevents passage through the opening, the door comprising a closure member which has a lower edge extending in a longitudinal direction, and intended to be moved opposite the threshold of the opening, and an edge upper edge spaced from the lower edge in a vertical direction perpendicular to the longitudinal direction, the closure system comprising a locking mechanism comprising at least:

[0008] a fixed or movable vertical beam in the longitudinal direction or rotating around the axis,

[0009] a cremone rod extending in the vertical direction being movable between a locking position in which the door is in a closed and locked position, and an unlocked position in which the door is in an open position or in a closed but not locked position, and

[0010] a bracket for receiving the rod, the bracket being arranged at a vertical end of the beam and having an L shape such that the bracket has a first portion extending in the vertical direction and a second portion extending in the longitudinal direction, the second portion of the bracket having an orifice receiving the rod in the vertical direction in the locking position of the rod, and not receiving the rod in the unlocked position of said rod.

[0011] Thanks to the L-shaped bracket receiving the rod in the vertical direction, the door and the beam are secured to each other when the rod is in the locking position. Thus, it is no longer necessary to drill the support, which facilitates adjustments and eliminates any risk of damage to said support. The safety of the closure system is also improved since the mechanical resistance is increased and it is much more difficult to separate two sliding doors or a sliding door from the beam with a tool.

[0012] The features set out in the following paragraphs may, optionally, be implemented, independently of one another or in combination with one another:

[0013] the locking mechanism comprises a rod guide member arranged at a vertical end of the door opposite the bracket, so as to guide the rod towards the hole in the bracket;

[0014] the rod guide member comprises a hollow profile delimiting a passage for the rod and pierced with one or more orifices, the profile extending at least partially along a lateral upright of the door in the vertical direction, the profile being provided to guide the rod in the vertical direction;

[0015] the closure system comprises a door, in which the locking mechanism comprises a fixed beam extending in the vertical direction, and in which the bracket is integral with the fixed beam and the rod is integral with the door, so that when the rod is received in the hole of the bracket, the door and the fixed beam are integral with each other.

[0016] the guide member is secured to a lateral upright of the door;

[0017] the closure system comprises a first sliding door and a second sliding door each opening in translation in an opposite direction along the longitudinal direction, or a first door and a second door each opening in rotation in an opposite direction along an axis of rotation parallel to the vertical direction, in which the bracket is integral with the first door carrying the beam, and the rod is integral with the second door, so that when the rod is received in the orifice of the bracket, the first door and the second door are integral with each other;

[0018] the guide member is secured to a lateral upright of the second door;

[0019] the locking mechanism further comprises a lock provided with a hook attached to the door and a latch attached to the beam;

[0020] the locking mechanism comprises a lower cremone rod and a lower bracket arranged on a lower part of the closure system, and / or an upper cremone rod and an upper bracket arranged on an upper part of the closure system;

[0021] the locking mechanism is mounted on the one hand in a first profile arranged on a side upright of the door, and on the other hand in a second profile arranged on the beam, adjacent to the side upright of the door in the closed position of the door, and in which, when the door is in the closed position, the first profile and the second profile overlap at least partially in the vertical direction;

[0022] the or each door is sliding and mounted to be movable in translation in a sliding direction, the closing system comprising, in addition to a guide rail for the door embedded in the floor, the door being provided along its lower edge with a guide complementary to the rail, the guide being provided with a noise-reducing pad along the entire length of the lower edge of the door.

[0029] In the figures, the same references designate identical or similar elements. Description of the embodiments

[0030] Figures 1 to 4 illustrate a first embodiment of a system 1 for closing an opening 3 made in a wall 2 and having a threshold 4.

[0031] In the embodiment shown in [Fig.l], the closure system 1 comprises two sliding doors 10 mounted to be movable in translation in a sliding direction C, respectively in opposite directions; each of the sliding doors 10 having an open position in which it allows passage through the opening 3 and a closed position in which it prevents passage through the opening 3.

[0032] The closure system 1 of [Fig.l] further comprises two fixed leaves 10' arranged on either side of the sliding doors 10, or sliding leaves 10, and mounted on the wall 2.

[0033] The invention is not limited to such a closure system 1 and applies to closure systems 1 comprising a single sliding door 10 (as will be shown in [Fig. 5]) or more than two sliding doors 10, as well as one or more than two fixed leaves 10'. The closure system 1 may also be without a fixed leaf.

[0034] The closure system 1 may comprise a mechanism 5 adapted to guide a translational movement in the sliding direction C of each of the sliding doors 10.

[0035] For each of the sliding doors 10, the mechanism 5 may comprise one or more guide rails 6 mounted on the wall 2, for example on a lintel of the opening 3, so as to extend in the sliding direction C. The mechanism 5 may also comprise one or more carriages mounted on the guide rail 6 and to which an upper edge 13 of the sliding door 10 is secured.

[0036] To achieve automatic movement of each sliding door 10 between the open and closed positions, the mechanism 5 may comprise a drive device (not shown). The drive device may in particular comprise an actuator, such as an electric motor, and a transmission mechanism adapted to transform a movement, for example rotation, of the actuator into a translational movement in the sliding direction C of the carriage. The mechanism 5 may then also comprise a control unit equipped with an activation device for moving each sliding door 10 between the open and closed positions.

[0037] The activation device may be a detection radar adapted to remotely detect the presence of an individual in the vicinity of each sliding door 10 in such a way that the control unit commands a passage of the sliding door 10 into the open position when the individual approaches the sliding door 10, and a passage of the sliding door into the closed position when the individual moves away from the sliding door 10. In other embodiments, a mechanism of any other suitable type could be provided. For example, the activation device could be a push button or a remote control.

[0038] Each of the sliding doors 10 comprises a closing member 11 which extends in a vertical direction Z from a lower edge 12 to the upper edge 13 and which has two lateral edges 14, spaced apart from each other in a longitudinal direction X perpendicular to the vertical direction Z. A transverse direction Y is also defined perpendicular to the longitudinal directions X and vertical Z.

[0039] In the embodiment shown, the closure member 11 is adapted to provide a thermal break. In particular, the closure member 11 comprises a double glazing unit retained in a frame. The frame comprises lower 15 and upper 16 crosspieces extending in the longitudinal direction X and respectively carrying the lower 12 and upper 13 edges of the closure member 11, and two uprights 17 extending in the vertical direction Z and respectively carrying the lateral edges 14 of the closure member 11.

[0040] In [Fig. 2] illustrating a cross-section of a lower part of the closure system 1, the lower crosspiece 15, as well as the upper crosspiece 16 and the uprights 17, is in the form of a profile 20 having overall rigidity and extending in one piece in a direction of extension. For the lower 15 and upper 16 crosspieces, the direction of extension corresponds to the longitudinal direction X and for the uprights 17, the direction of extension corresponds to the vertical direction Z.

[0041] As shown in [Fig.2], the fixed leaf 10' may comprise a closure member 11 having a structure identical to that of the closure member 11 of the sliding door 10. This structure will not be described again in detail and reference will be made to the description of the structure of the closing member 11 of the sliding door 10 for further details on the structure of the fixed leaf 10'.

[0042] Advantageously, the closure system 1 has a locking mechanism 50 visible in Figures 1, 3 and 4, and comprising at least:

[0043] a fixed or movable vertical beam 51 in the longitudinal direction X,

[0044] a cremone rod 52 (shown by transparency) extending in the vertical direction Z being movable between a locking position in which the sliding door 10 is in the closed and locked position, and an unlocked position in which the sliding door 10 is in the open position or in the closed but not locked position, and

[0045] a bracket 54 (shown by transparency) for receiving the rod 52, the bracket 54 being arranged at a vertical end 53 of the beam 51 and having an L shape so that the bracket 54 has a first portion 56 extending in the vertical direction Z and a second portion 58 extending in the longitudinal direction X, the second portion 58 of the bracket 54 having an orifice 60 receiving the rod 52 in the vertical direction Z in the locking position of the rod 52, and not receiving the rod 52 in the unlocked position of said rod 52.

[0046] In the embodiment of [Fig.l], the locking mechanism 50 has a cremone bolt lock 62 comprising a barrel 64 provided with a hook 66 secured to one of the sliding doors 10, and the lock 62 comprising a strike plate 68 secured to the other sliding door 10.

[0047] Thus, when the sliding doors 10 are in the closed position, the action of a user on the lock 62 makes it possible to engage the hook 66 in the strike plate 68 and thus to lock the automatic doors 10.

[0048] The lock 62 provides the closure system with an additional security point.

[0049] The lock 62 is in particular placed in the central part of the two uprights 17 adjacent, each upright 17 belonging to a separate sliding door 10.

[0050] In the embodiment of [Fig.l], the beam 51 is mounted on the side upright 17 of one of the sliding doors 10 carrying the rod 52, in particular two rods 52 comprising a lower rod 52' and an upper rod 52”. The lower rod 52' extends from the lock 62 towards the lower crossbar 15. The upper rod 52” extends from the lock 62 towards the upper crossbar 16.

[0051] The locking mechanism 50 of [Fig.l] comprises in particular a lower bracket 54' and an upper bracket 54”.

[0052] Each bracket 54 is for example made of metal, in particular stainless steel.

[0053] As visible in [Fig. 3], the lower bracket 54' is arranged in the lower part of the upright 17 of the sliding door 10 not carrying the lower rod 52', said upright 17 being adjacent to the upright 17 of the other sliding door 10 carrying the lower rod 52'. The lower bracket 54' forms an L having a first portion 56 extending in the vertical direction Z and a second portion 58 extending in the longitudinal direction X. The first portion 56 is in particular longer in the vertical direction Z than the second portion 58 in the longitudinal direction X. The second portion 58 of the lower bracket 54' extends below the first portion 56 in the vertical direction Z when the closure system 1 is installed.

[0054] In the same way, the upper bracket 54'' is arranged in the upper part of the upright 17 of the sliding door 10 not carrying the upper rod 52”, said upright 17 being adjacent to the upright 17 of the other sliding door 10 carrying the upper rod 52”. The upper bracket 54” forms an L having a first portion 56 extending in the vertical direction Z and a second portion 58 extending in the longitudinal direction X. The first portion 56 is in particular longer in the vertical direction Z than the second portion 58 in the longitudinal direction X. The second portion 58 of the upper bracket 54” extends above the first portion 56 in the vertical direction Z when the closure system 1 is installed.

[0055] When a user actuates the locking mechanism 50, the upper rod 52” is actuated vertically upwards until it engages in the hole 60 of the upper bracket 54”, and the lower rod 52' is actuated vertically downwards until it engages in the hole 60 of the lower bracket 54'. When the two lower rods 52' and upper rods 52” are respectively engaged in the lower bracket 54' and the upper bracket 54”, the two sliding doors 10 are secured to each other. This makes them mechanically more resistant to an attempt at break-in by spreading.

[0056] The invention is not limited to such a closure system 1 and applies to closure systems 1 comprising a single rod and a single bracket in the upper or lower part of the closure system 1.

[0057] According to an advantageous aspect, the closure system 1 comprises, for each bracket 54 and each rod 52, a guide member 70 (shown by transparency) for the rod 52 arranged at a vertical end 71 of the sliding door 10 opposite the bracket 54, so as to guide the rod 52 towards the orifice 60 of the bracket 54.

[0058] The guide member 70 extends at least partially along a lateral upright 17 of the sliding door 10 in the vertical direction Z.

[0059] The guide member 70 is integral with a lateral upright 17 of the sliding door 10 not carrying the bracket 54 and is placed opposite the respective bracket 54.

[0060] As visible in [Fig.4], the guide member 70 comprises in particular a hollow profile 72 delimiting a passage of the rod 52, the profile 72 being provided to guide the rod 52 in the vertical direction Z. The shape of the passage is designed to be complementary to the shape of the rod 52. The passage delimited by the profile 72 takes for example a shape complementary to a cylinder adapted for a cylindrical rod 52.

[0061] The guide member 70 is in particular pierced with orifices 74, in particular 4 orifices 74, in the vertical direction Z. Said orifice(s) 74 make it possible to fix the guide member 70 to the lateral upright 17 of the sliding door carrying the guide member 70 by means of a screw in a very robust manner in order to limit or even make impossible the twisting of the rod 52 in the event of an attempt to move the doors apart.

[0062] The guide member 70 is for example made of polymer material, comprising in particular polyethylene with a very high molar mass.

[0063] Advantageously, the orifice 60 of the bracket 54 is aligned with the passage of the rod 52 delimited by the guide member 70. Thus, when a user actuates the locking mechanism 50, the guide member 70 guides the rod 52 to the orifice 60 of the bracket 54. This thus ensures optimal locking of the rod 52 in the bracket 54 and thus an improvement in the security of the closure system 1 in the event of an attempted break-in.

[0064] Advantageously, the locking mechanism 50 is mounted on the one hand in a first profile 76 arranged on a lateral upright 17 of the first sliding door 10, and on the other hand in a second profile 78 arranged on a lateral upright of the second sliding door 10, adjacent to the lateral upright 17 of the first sliding door 10 in the closed position of the sliding doors 10.

[0065] The first profile 76 and the second profile 78 are for example made of metal, in particular aluminum.

[0066] According to an advantageous aspect, the first profile 76 and the second profile 78 have, preferably over the entire height in the vertical direction Z, an overlap 79.

[0067] In this way, when the sliding doors 10 are in the closed position, the passage of a tool is made even more difficult to separate the two sliding doors 10.

[0068] As visible in [Fig.2], the closure system 1 advantageously further has a rail 80 for guiding the sliding doors 10 embedded in the floor, and held by means of screws 82. Each sliding door 10 is then provided along its lower edge 12 with a guide 84 complementary to the rail 80. The guide 84 is preferably made of metal, for example aluminum. According to a preferred aspect, the guide 84 is provided with a noise-reducing pad 86 along the entire length of the lower edge 12 of the sliding door 10. Thus, the thermal break between the exterior and the interior is maintained, the sound insulation is also improved, and the passage of a tool under the sliding doors 10 is made impossible. The safety of the shutter system is therefore improved.

[0069] Resistance tests were carried out with respect to this first embodiment. The two sliding doors 10 were moved into the closed position by locking the lower 52' ​​and upper 52” rods in the holes 60 of the lower 54' and upper 54” brackets. An attempt was made to introduce a tool having a surface area of ​​one square centimeter with a weight of 600 kg for 40 seconds between the two sliding doors 10, or sliding leaves 10, to separate them. This did not work. The locking mechanism according to the invention therefore offers very high resistance to the separation of the leaves by a tool.

[0070] In the embodiment shown in [Fig. 5], the closure system 1 comprises a sliding door 10 mounted to be movable in translation in a sliding direction C, the sliding door 10 having an open position in which it allows passage through the opening 3 and a closed position in which it prevents passage through the opening 3, and a fixed leaf 10' arranged parallel to the sliding door and which the sliding door covers at least partially in the transverse direction Y when the sliding door Y is in the open position.

[0071] In this embodiment, the locking mechanism 50 comprises a fixed beam 51 extending in the vertical direction Z. The fixed beam 51 is mounted on a wall 92 of the support delimiting the opening which the closing system 1 closes.

[0072] In this embodiment, for each bracket 54 and each rod 52, the bracket 54 is secured to the fixed beam 51 and the rod 52 is secured to the sliding door 10, so that when the rod 52 is received in the orifice 60 of the bracket 54, the sliding door 10 and the fixed beam 51 are secured to each other.

[0073] In the embodiment of [Fig. 5], the locking mechanism 50 comprises, as described for [Fig. 1], two rods 52 comprising a lower rod 52' and an upper rod 52”. The lower rod 52' extends from the lock 62 towards the lower crossbar 15. The upper rod 52” extends from the lock 62 towards the lower crossbar 16.

[0074] In the embodiment of [Fig. 5], the locking mechanism 50 has a cremone bolt lock 62 comprising a barrel 64 provided with a hook 66 secured to the sliding door 10, and the lock 62 comprising a strike plate 68 secured to the fixed beam 51.

[0075] Thus, when the sliding door 10 is in the closed position, the action of a user on the lock 62 makes it possible to engage the hook 66 in the strike plate 68 and thus to lock the automatic door 10.

[0076] The lock 62 provides the closure system with an additional security point.

[0077] The locking mechanism 50 of [Fig.5] comprises in particular, as for [Fig.l], a lower stem 54' and an upper stem 54”.

[0078] The lower bracket 54' is arranged in the lower part of the upright 17 of the sliding door 10 not carrying the lower rod 52', said upright 17 being adjacent to the upright 17 of the other sliding door 10 carrying the lower rod 52'. The lower bracket 54' forms an L having a first portion 56 extending in the vertical direction Z and a second portion 58 extending in the longitudinal direction X. The first portion 56 is in particular longer in the vertical direction Z than the second portion 58 in the longitudinal direction X. The second portion 58 of the lower bracket 54' extends below the first portion 56 in the vertical direction Z when the closure system 1 is installed.

[0079] In the same way, the upper bracket 54” is arranged in the upper part of the upright 17 of the sliding door 10 not carrying the upper rod 52”, said upright 17 being adjacent to the upright 17 of the other sliding door 10 carrying the upper rod 52”. The upper bracket 54” forms an L having a first portion 56 extending in the vertical direction Z and a second portion 58 extending in the longitudinal direction X. The first portion 56 is in particular longer in the vertical direction Z than the second portion 58 in the longitudinal direction X. The second portion 58 of the upper bracket 54” extends above the first portion 56 in the vertical direction Z when the closure system 1 is installed.

[0080] When a user actuates the locking mechanism 50, the upper rod 52” is actuated vertically upwards until it engages in the hole 60 of the upper bracket 54”, and the lower rod 52' is actuated vertically downwards until it engages in the hole 60 of the lower bracket 54'. When both the lower rod 52' and the upper rod 52” are engaged respectively in the lower bracket 54' and the upper bracket 54”, the sliding door 10 and the fixed beam 51 are secured to each other. This makes them mechanically more resistant to an attempted break-in by passing a tool between the sliding door 10 and the fixed beam 51.

[0081] According to an advantageous aspect, in the same way as described previously, the closure system 1 of [Fig. 5] comprises, for each bracket 54 and each rod 52, a guide member 70 (shown by transparency) of the rod 52 arranged at a vertical end 71 of the sliding door 10 opposite the bracket 54, so as to guide the rod 52 towards the orifice 60 of the bracket 54.

[0082] The guide member 70 extends at least partially along a lateral upright 17 of the sliding door 10 in the vertical direction Z.

[0083] The guide member 70 is secured to a lateral upright 17 of the sliding door 10 and is placed opposite the respective bracket 54.

[0084] Advantageously, the locking mechanism 50 is mounted on the one hand in a first profile 76 arranged on a lateral upright 17 of the sliding door 10, and on the other hand in a second profile 78 arranged on the fixed beam 51, adjacent to the lateral upright of the first sliding door 10 in the closed position of the sliding door 10.

[0085] The first profile 76 and the second profile 78 are for example made of metal, in particular aluminum.

[0086] The first profile 76 and the second profile 78 have, preferably over the entire height in the vertical direction Z, an overlap 79.

[0087] In this way, when the sliding door 10 is in the closed position, the passage of a tool is made even more difficult to separate the sliding door 10 from the fixed beam 51 against which it rests.

[0088] The closure system 1 advantageously further has a guide rail 80 for the sliding door 10 embedded in the floor. The sliding door 10 is then provided along its lower edge 12 with a guide 84 complementary to the rail 80. The guide 84 is preferably made of metal, for example aluminum. According to a preferred aspect, the guide 84 is provided with a noise-reducing pad 86 over the entire length of the lower edge 12 of the sliding door 10. Thus, the thermal break between the outside and the inside is maintained, the sound insulation is also improved, and the passage of a tool under the sliding door 10 is made impossible. The safety of the closure system is therefore improved.

[0089] Resistance tests were carried out with respect to this second embodiment. The sliding door 10 was moved into the closed position by locking the lower 52' ​​and upper 52” rods in the holes 60 of the lower 54' and upper 54” brackets. An attempt was made to introduce a tool having a surface area of ​​one square centimeter with a weight of 600 kg for 40 seconds between the sliding door 10 and the fixed beam 51, to separate them. This did not work, and the test was even extended to ten minutes, without success. The locking mechanism according to the invention therefore offers very high resistance to the forced opening of the door by a tool.

[0090] The embodiments illustrated herein are described with one or more sliding doors. According to variations of these embodiments, the closure system may also comprise one or two doors opening in rotation around an axis parallel to the vertical direction Z. The locking mechanism described above is installed in the same way between two sliding doors opening in an opposite direction in the longitudinal direction as between two doors opening in an opposite direction in rotation.

[0091] Similarly, the locking mechanism described above is installed in the same way between a sliding door and a fixed beam as between a rotating door and a fixed beam.
