Description

Sectional door with manual lateral movement incorporating a gate and a closing/locking system on the discharge side

This patent application concerns a sectional door with lateral manual movement, integrating a door and a closing/locking system on the discharge side.

Prior art

A sectional door is used to close an opening in a frame, for example in a garage. It is made up of a succession of flat panels hinged to each other, including two end panels (one on each side of the sectional door) and one or more intermediate panels between the two end panels.

The opening of a sectional door with manual lateral movement is carried out by manual sliding of the panels in a fixed slide frame secured to the frame, which fixed slide frame comprises in particular a horizontal upper rail and a horizontal threshold provided with guide pads, the upper rail having a first rectilinear portion along the opening of the frame, this first rectilinear portion corresponding to the location of the sectional door in the closed position, a second rectilinear portion inside the frame corresponding to the location of the sectional door in the open (or pushed back) position, and a curved portion connecting the two rectilinear portions. The “ direction of delivery ” corresponds to the direction of said upper rail and the “ direction of delivery ” corresponds to the direction of movement of the sectional door from its closed position to its open position (it therefore goes from the first rectilinear portion to the second portion straight line of the upper rail).

In the closed position, the sectional door forms a parallelepiped having a generally flat interior face oriented towards the inside of the frame, a generally flat exterior face oriented towards the exterior of the frame, an upper horizontal edge which cooperates with the upper rail of the slide frame fixed (this edge is rectilinear and coupled with the first rectilinear portion of the rail when the sectional door is in the closed position), a lower horizontal edge which cooperates with the guide shoes carried by the threshold, a vertical lateral edge on the discharge side and a vertical lateral edge on the side opposite the discharge.

In addition to the upper rail, the threshold and the guide pads, the fixed slide frame includes in particular a vertical stop/locking amount on the side opposite the discharge, which amount forms a stop against which the sectional door abuts in the closed position; it is also used to lock the sectional door as explained below.

In a sectional door with lateral manual movement, it is known to provide a gate on the side opposite the discharge, the gate corresponding to the end panel of the sectional door located on the side opposite the discharge. The gate has a first vertical edge hinged on the adjacent intermediate panel and a second free vertical edge, opposite the first hinged vertical edge, the free vertical edge of the gate forming the vertical lateral edge of the sectional door on the side opposite the discharge.

A closing and locking system allows both the sectional door and the gate to be closed and locked. It usually comprises on the one hand a latch bolt operated by a handle for closing the sectional door and the gate, and on the other hand at least one deadbolt operated by a key for locking the sectional door and the door. gate. The latch bolt can be moved laterally in the plane of the gate using the handle between an open position in which the bolt is retracted into the thickness of the gate and a closed position in which the bolt extends protruding of the free vertical edge of the gate and is engaged in a striker provided in the vertical stop/locking amount of the fixed slide frame (on the side opposite the discharge). Likewise, actuation of the key causes the lateral movement of the deadbolt which thus engages in a corresponding striker provided in the vertical stop/locking amount.

With such a system, it is impossible to place the gate and the closing/locking system on the discharge side, because the vertical stop/locking upright would then be in the path of the sectional door and would prevent it from opening. If we want to use a closing/locking system as previously described, the gate and the closing/locking system must therefore necessarily be provided on the side opposite the discharge.

However, it would be interesting, particularly in renovation when the frame is existing and the environment of the sectional door is fixed, to be able to choose on which side the door and the closing/locking system are placed.

There are, however, sectional doors with manual lateral movement incorporating a door located on the discharge side, but these sectional doors are equipped with much more complex locking systems and sliding frames (a system of connecting rods is notably necessary to shift the sectional door transversely). during its journey) and therefore more expensive than classic locking systems and classic slide frames, described above.

The invention aims to solve this problem by providing a sectional door with lateral manual movement, integrating a gate and a closing/locking system on the discharge side and whose design is simple and inexpensive. The main objective of the invention is to achieve this objective by using a classic slide frame and a classic lock closing/locking system adapted at lower cost, without sacrificing the security and performance of the lock.

Another objective of the invention is to make it possible to multiply at will the number of locking points in a sectional door according to the invention, without this leading to significant modifications to the closing/locking system. The closing/locking system can then be produced industrially at lower cost while being easily adaptable to the needs and wishes of customers.

Throughout the description, the term “transversely” refers to a transverse direction which is orthogonal to the front faces of the sectional door and/or wicket door (depending on the context), while the term “laterally” refers to a horizontal direction. included in the plane of the sectional door and/or the gate, that is to say in a horizontal direction parallel to the front faces of the sectional door and/or the gate.

To achieve the objectives set, the invention proposes a sectional door with lateral manual movement, integrating a gate and a closing/locking system, said sectional door being configured to close an opening in a frame, the gate being able to be pivoted between a closed position and an open position, the sectional door being able to be moved manually along a path of movement between a closed position and an open position when the gate is in the open position, the sectional door and the gate in the closed position closing the opening of the frame, said closing/locking system comprising a lock arranged in the thickness of the gate in a vertical framing profile of said gate, said lock comprising a closing bolt which can be moved laterally between a closed position in which it is 'extends laterally from the vertical framing profile of the gate and an open position in which it is retracted into said vertical framing profile.

The sectional door according to the invention is characterized in that:

- the gate is located on the discharge side,

- the closing/locking system comprises an offset bolt, extending essentially in a transverse direction, which offset bolt has a first end fixed on the closing bolt of the lock and an opposite end provided with a closing head coming into transversely projecting from a first front face of the gate,

- the closing/locking system includes

a vertical upright, called the striker support upright, rigidly fixed to the frame on the side of the first front face of the gate, facing and at a transverse distance from the vertical framing profile of the gate when the gate and the sectional door are in the closed position,

and a closing striker, fixed to the striker support post and configured to receive the closing head of the offset bolt when the sectional door and the gate are in the closed position and to retain said closing head transversely when the sectional door, the gate and the closing bolt are in the closed position.

The striker support post being offset transversely from the vertical frame profile of the gate when the gate and the sectional door are in the closed position, it is offset transversely from the upper rail in which the sectional door slides. It is therefore not on the movement path of the sectional door. When the sectional door is manually moved from its closed position to its open position, with the door in the open position, the sections of the sectional door pass in front of the striker support post and the closing striker without coming into contact with them.

According to a possible characteristic of the invention, the closing head of the offset bolt comprises a blocking shoulder, and the closing striker has an upstream vertical edge against which the offset bolt abuts when the gate, the sectional door and the bolt closing are in the closed position, the blocking shoulder then preventing the transverse movement of the offset bolt and the pivoting of the door.

According to a possible characteristic of the invention, the closing striker is formed by a plate folded in Z (according to two vertical folds), so that it has on the one hand a flat portion which extends parallel to the first face front of the gate, between the vertical framing profile of the gate and the striker support amount, when the sectional door and the gate are in the closed position, and on the other hand a fixing bracket for fixing the closing striker to the striker support post.

Like a conventional lock, the lock further comprises one or more exit pins which can be operated by a key between an unlocked position in which each exit pin is retracted inside the vertical framing profile of the gate and a locked position in which said exit pin extends laterally from said vertical framing profile. According to a possible characteristic of the invention, the closing/locking system then comprises:

- a plurality of offset locking pins, each carried by a rod fixed to at least one output pin, preferably to at least two output pins, the offset locking pins being located transversely facing the striker support amount when the sectional door and the gate are in the closed position,

- for each offset locking pin, a locking striker fixed on the striker support post, each offset locking pin having a locking head configured to be inserted into the corresponding locking striker when the sectional door and the gate are in the closed position and to be retained by said locking striker when the sectional door and the gate are in the closed position and the exit pins are in the locked position.

Note that the previously defined characteristic according to which each offset locking pin is carried by a rod, covers the following various cases:

- The closing/locking system includes as many rods as there are offset locking pins, each pin then being carried by a rod which is its own.

- The closing/locking system includes a single rod carrying all the offset locking pins, that is to say a single rod common to all the offset locking pins.

- Any intermediate scenario in which the closing/locking system comprises several rods, each of which carries one or more offset locking pins.

According to a possible characteristic, each rod comprises on the one hand a transverse plate which extends in a transverse plane facing laterally the vertical framing profile of the gate, which transverse plate is carried by at least one, and preferably two, exit pins from the locking system. The rod further comprises, for each offset locking pin that it carries, a front exterior arm on which said locking pin is fixed, which front exterior arm extends substantially parallel to the first front face of the gate and is located next to the striker support post when the sectional door and the gate are in the closed position.

Here again, the characteristic according to which “the rod comprises, for each offset locking pin that it carries, a front exterior arm on which said offset locking pin is fixed” covers the various cases below:

- The rod includes as many front exterior arms as there are offset locking pins on the sectional door said rod, each offset pin being fixed on an arm of its own.

- The rod comprises a single front exterior arm on which all the offset locking pins carried by said rod are fixed, the arm therefore being common to all the offset locking pins of the rod in question. The rod then has the shape of an angle or a square, with a transverse plate by which it is fixed to the exit pins of the lock and a front plate on which the offset locking pins are fixed.

-All “intermediate” scenarios are possible, in which the rod comprises several front exterior arms, each arm carrying one or more offset locking pins.

According to one possible characteristic, the locking head of the offset locking pins comprises a collar, for example of circular section. Furthermore, each locking striker comprises a folded plate having a core which extends substantially parallel to the first front face of the gate when the sectional door and the gate are in the closed position, facing the striker support amount, which core is provided with a generally V-shaped notch open laterally in the direction opposite to the discharge.

Said V-shaped notch preferably has an opening having a width greater than an external diameter of the locking head of the offset locking pin in order to receive said locking head transversely when the sectional door and the gate are in the closed position and the pins lock exit are in the unlocked position. The V-shaped notch may, however, have an opening having a width less than the external diameter of the flange of the offset locking pin but greater than the diameter of another portion of said locking pin, to be able to receive the locking head laterally when the door sectional and the gate are in the closed position and the lock exit pins are moved from their locked position to their locked position.

The V-shaped notch also has a point (opposite its opening) having an internal radius less than the external diameter of the flange of the offset locking pin in order to retain transversely the locking head of said pin when the door sectional and the gate are in the closed position and the lock exit pins are in the locked position.

The invention also relates to a closing/locking system as previously described, that is to say a closing/locking system for a sectional door with manual lateral movement integrating a door located on the discharge side of the sectional door, said closing/locking system comprising a lock intended to be arranged in the thickness of the gate in a vertical framing profile of said gate, said lock comprising a central box, as well as a closing bolt which can be moved laterally between a closed position in which it extends laterally from the central trunk and an open position in which it is retracted into said central trunk.

The closing/locking system according to the invention is characterized in that it comprises:

- an offset bolt, extending essentially in a transverse direction, which offset bolt has a first end fixed on the closing bolt of the lock and an opposite end provided with a closing head which projects transversely from a first front face of the gate when the lock is arranged in the gate,

- a vertical upright, called a striker support upright, configured to be rigidly fixed to a frame and intended to be arranged on the side of the first front face of the gate so as to be facing and at a transverse distance from the vertical framing profile of the gate when the gate and the sectional door are in a closed position (in which they close an opening in the frame),

- and a closing striker, fixed to the striker support amount and configured to receive the closing head of the offset bolt and to retain said closing head transversely.

This closing/locking system may have one or more of the characteristics previously described.

In particular, the closing striker can be formed by a Z-folded plate, which has on the one hand a flat portion which is intended to extend substantially parallel to the first front face of the gate, between the vertical framing profile of the door and the striker support amount, when the striker support amount is fixed to the frame and the sectional door and the door are in the closed position, and on the other hand a fixing bracket for fixing the closing striker to the striker support post.

Furthermore, the lock advantageously comprises exit pins associated with the central box and/or output pins associated with a box, all the output pins being able to be actuated simultaneously by a key between an unlocked position, in which the output pins are retracted, respectively, inside the central trunk or the housing, and a locked position in which said output pins extend laterally projecting from said central trunk and housing. The lock may preferably comprise several, for example two, boxes as previously defined. In particular, the lock advantageously comprises an upper housing, intended to be located near the upper edge of the gate, and a lower housing intended to be located near the lower edge of the gate. Each of these boxes can be provided with one or more (preferably two) output pins.

In this case, the closing/locking system also includes:

- a plurality of offset locking pins, each carried by a rod fixed to at least one output pin, the offset locking pins being located transversely facing the striker support post when said post is fixed to the frame and the sectional door and the gate are in the closed position, and

- for each offset locking pin, a locking striker fixed on the striker support post, each offset locking pin having a locking head configured to be inserted into the corresponding locking striker and to be retained transversely by said striker locking when the output pins are in the locked position.

The locking head of the offset locking pins may include a collar. Each locking striker then comprises, for example, a folded plate having a core which is intended to extend substantially parallel to the first front face of the gate, between the vertical framing profile of the gate and the striker support amount, when the striker support amount is fixed to the frame and the sectional door and the gate are in the closed position, which core is provided with a generally V-shaped notch open laterally in the direction opposite to the discharge, said V-shaped notch having a point having a internal radius less than the external diameter of the flange of the offset locking pin in order to retain transversely the locking head of said pin when the sectional door and the gate are in the closed position and the exit pins of the lock are in the locked position.

detailed description

The identical elements represented in the aforementioned figures are identified by identical numerical references.

Figures 1 and 2 show a sectional door 2 according to the invention, comprising a plurality of panels 20-22 hinged one after the other, including an end panel 20 on the discharge side, an end panel 21 on the side opposite the discharge and three intermediate panels 22 between the two end panels. Of course, the invention is not limited to a sectional door comprising the number of panels represented here.

The sectional door 2 is movable laterally between a closed position shown in and an open position, the arrow R indicating the direction in which the sectional door is moved when it opens, which is called the direction of discharge. There illustrates the sectional door in an intermediate partial opening position.

The sectional door is associated with a sliding frame comprising at least one upper rail 6 in which the upper edge of the sectional door can slide, a lower threshold 8, guide pads 80 in which the lower edge of the sectional door can slide, a vertical stop amount 10 on the side opposite the discharge and against which the sectional door abuts in the closed position. When in the closed position, the sectional door closes an opening in a frame (not shown).

In known manner, the upper rail 6 comprises a first rectilinear portion 60 along the opening of the frame, a second rectilinear portion 61 on the discharge side, the second rectilinear portion being generally orthogonal to the first, and a curved portion 62, here in an arc, connecting the two rectilinear portions 60, 61.

Usually, one of the end panels of the sectional door forms a door 200, which must be opened in order to unlock and open the sectional door itself, and the sectional door includes a closing/closing system. locking at this gate, locking/unlocking of the gate causing locking/unlocking of the sectional door.

According to the invention, this gate 200 is essentially formed by the end panel 20 located on the discharge side (while it is located on the side opposite the discharge in the vast majority of known previous sectional doors), and the system of closing/locking is located on the delivery side, the vertical stop amount 10 on the side opposite the delivery serving only as a stop at the end of the stroke when closing the sectional door (while it contains locking elements in the vast majority of known prior systems).

The gate 200 comprises on the one hand the panel 20, the front faces of which respectively form the inner front face 201 of the gate and the outer front face 202 of the gate (that is to say the front face of the gate oriented, respectively, towards the inside or outside of the frame when the gate is in the closed position), and on the other hand a frame surrounding the panel on its edge. The frame includes in particular a vertical framing profile 203 (cf. ) on the side of the free vertical edge of the gate.

The closing/locking system of the sectional door 2 comprises a classic lock 30 as illustrated in , comprising a central box 300 embedded in the thickness of the gate from the free vertical edge thereof (which, according to the invention, corresponds to the vertical side edge of the sectional door on the discharge side). This box is closed by a headrest 301 pressed against the vertical framing profile 203 of the gate.

Usually, the lock 30 further comprises a closing bolt 302, for example a latch bolt, which can be operated using a handle 306 (visible on the and 2), via a known mechanism (not shown) housed in the box 300. The closing bolt 302 can be observed in the open position (handle depressed) at the ; in this position, it is retracted into the central box 300 of the lock inside the vertical framing profile 203 of the gate. The closing bolt 302 is visible in the closed position (handle released) at the ; in this position, it extends outside the trunk and the panel 20, projecting laterally from the vertical framing profile 203 of the door and from the faceplate 301 of the lock.

According to the invention, the closing/locking system further comprises an offset bolt 40 ( to 7) which extends essentially in the transverse direction, between a first end 401 fixed to the closing bolt 302 and a free end (opposite) provided with a closing head 402 located projecting transversely from the external front face (or first front face) 202 of the gate.

The offset bolt 40 being fixed to the closing bolt 302 of the lock, actuation of the gate handle causes the lateral movement of the offset bolt, which can thus be moved between a closed position illustrated in and an open position corresponding to the .

The closing/locking system of the sectional door further comprises a striker support post 50 extending vertically, on which various strikers described below are fixed. We find this strike support amount 50 in all the figures with the exception of the . The strike support amount 50 can be a vertical tubular profile of generally rectangular section. Other forms are of course possible. It is fixed to the frame facing and at a transverse distance from the free lateral edge of the gate (that is to say the vertical framing profile 203) when the gate and the sectional door are in the closed position.

The closing/locking system of the sectional door also includes a closing striker 510 fixed on the striker support post 50 at the height of the offset bolt 40.

In the example illustrated, the closing striker 510 is formed from a plate cut and folded in two vertical folds so as to present a flat portion forming a stop 5101 which extends transversely from the striker support amount 50, parallel to the front face 202 of the gate when the gate and the sectional door are in the closed position, a flat portion 5103 parallel to the portion forming a stop 5101 and pressed against the strike support amount 50, and a flat portion 5102 connecting the portions 5101 and 5103, the flat portions 5102 and 5103 forming a fixing tab making it possible to fix the closing striker 510 to the striker support amount 50 using two screws for example.

The closing head 402 of the offset bolt has a blocking shoulder 403. When the closing bolt 302, and consequently also the offset bolt 40, are in the closed position ( and 5, gate handle released), the offset bolt 40 is pressed against the upstream vertical edge 5104 of the closing striker 510. The opening of the gate according to the arrow O is prevented by the blocking shoulder 403 of the offset bolt which abuts against the portion forming a stop 5101 of the closing striker.

When the closing bolt 302, and therefore also the offset bolt 40, are in the open position ( and 7, gate handle pressed), the shoulder 403 is released from the closing striker 510. The gate can be pivoted in the direction O to allow it to open. The sectional door can then be moved manually in the lateral delivery direction R, the striker amount 50 in no way hindering this movement.

The lock 30 further comprises key locking means. Preferably, it is a multipoint lock whose faceplate 301 (see ) extends over all or a large part of the height of the vertical framing profile 203 of the gate. The lock further comprises, at an upper housing 303, a lower housing 304 and the (central) box 300, output pins 305 which can be moved together, by actuation of a key, between an unlocked position in which they are retracted inside the upper boxes 303, 304 and the central box 300 respectively, and a locked position in which they extend laterally outside the boxes and the central box, projecting laterally from the headrest 301.

In the example illustrated, the lock 30 comprises two upper output pins in the upper casing 303, two central output pins in the case 300 and two lower output pins in the lower casing 304. Of course, the invention does not is not limited to such a lock; it applies to locks having a different number of exit pins or distributed differently along the faceplate 301.

The closing/locking system according to the invention comprises offset locking pins 70 carried by one or more rods 60. In the example illustrated, the closing/locking system comprises three rods 60, namely: an upper rod at height of the upper casing 303, fixed to the two output pins of said upper casing, a central rod at the height of the central box 300, fixed to the two output pins of said central box, and a lower rod at the height of the lower box 304, fixed to the two pins outlet of said lower housing.

Each rod 60 comprises a transverse plate 601, which extends parallel to the faceplate 301 and is fixed to the output pins 305 of the lock, and one or more front exterior arms 602a, 602b, which extend parallel to the front face exterior 202 of the gate, facing the striker support amount 50 (when the gate and the sectional door are in the closed position). A remote locking pin 70 is fixed to each of the front exterior arms 602a, 602b of the rod. Each offset locking pin 70 is thus located between the vertical framing profile 203 of the gate and the striker support amount 50.

The closing/locking system according to the invention further comprises, for each offset locking pin 70, a locking striker 520 fixed to the striker support post 50. Each locking striker comprises a notch 5201 generally in the shape of a lying V, open laterally in the opposite direction to the discharge. Said locking striker 520 can be formed by a rectangular plate folded in four horizontal folds so as to present a central core which extends facing and at a distance from the striker support amount 50, parallel to the exterior front face 202 of the gate when the sectional door and the gate are in the closed position, the V-shaped notch 5201 being formed in the central core of the locking striker. In addition to this central core, the 520 locking striker has an upper fixing lug and a lower fixing lug, for its attachment to the striker support post using screws.

Each offset locking pin 70 being fixed to a rod 60, itself fixed to two output pins 305, the actuation of the gate key causes the lateral movement of the offset locking pins 70, which can thus be moved between a locked position shown in and 11 and an unlocked position corresponding to the and 9.

Each offset locking pin 70 includes a locking head 701 provided with a collar 702, in the circular example. The opening 5202 of the V-shaped notch has a diameter greater than the external diameter of the flange 702, so that the locking head 701 of the offset locking pin is inserted into the opening 5202 of the V-shaped notch when the sectional door and the gate are in the closed position and the exit pins 305 are in the unlocked position. The collar 702 is then free to come out of the locking striker. The gate can be pivoted in the O direction to allow it to open. The sectional door can then be moved manually in the lateral delivery direction R, the striker amount 50 in no way hindering this movement.

Conversely, the tip 5203 of the V-shaped notch has a diameter less than the external diameter of the collar 702, so that the collar is retained transversely by the point 5203 of the V when the sectional door and the gate are in position closed and that the exit pins 305 are in the locked position, which prevents the pivoting of the gate 200 according to arrow O.

Note that a seal 530 is attached to the striker support post 50. This seal extends over the entire height of the gate. When the sectional door and the gate are in the closed position ( to 11), the exterior front face 202 of the gate bears against said seal 520.

The invention thus offers the possibility of providing a gate on the discharge side and of equipping it with an efficient and inexpensive closing and locking system, this being simple to manufacture on the basis of the operation of a classic lock.

In addition, the closing/locking system can be equipped with as many offset locking pins 70 as the customer wishes while being produced in a standardized and industrial manner. It can for example be planned to produce rods 60 of different lengths, equipped with 2 or 3 (or even more) offset locking pins 70 depending on the length of said rods.

The invention is not limited to the illustrated embodiments. For example, the V-shaped notch of the locking strikers could be generally rectangular with a width less than the external diameter of the flange 702 of the offset locking pin. In this case, the positioning of the locking striker on the striker support post is such that, when the sectional door and the gate are in the closed position and the exit pins in the unlocked position, the locking head of the offset locking pin is located laterally next to the opening of the notch, ready to be inserted into the notch when the output pins are then moved (laterally) towards their locking position. A V-shaped notch is preferred in that it facilitates adjustment of the closing/locking system, and guarantees snag-free entry of the offset locking pin into the notch. In another variant, the V-shaped notch of the locking strikers could be replaced by a hole in the shape of a lying drop of water, made directly in the striker support amount 50 or made in a plate forming a striker similar to that illustrated, fixed to the striker support amount.

In addition, the closing/locking system could include, not three rods 60 but a single rod extending from the upper housing 303 to the lower housing 304, carried by all the output pins 305. This rod may have a desired number of front exterior arms, each carrying an offset locking pin, distributed over the entire height of the gate. Furthermore, in the example illustrated, each offset locking pin is carried by an exterior front arm specific to it; one could provide exterior front arms each extending over a height greater than that illustrated in order to sectionally carry several pins offset locking pins, or even a single exterior front arm extending over the entire height of the rod and on which all the offset locking pins would be fixed.

Furthermore, the striker support post may have a section different from that illustrated, have reinforcing ribs, etc.
