Description

The present invention relates to a door panel comprising a new lock system particularly meeting the needs of people with disabilities.

The search for new reliable locking equipment in the form of locks for doors in particular, continues to attract much interest. Ideally, the most reliable locks have multiple points of closure, for example 3 organs or locking bolts. Despite the large number of locks that exist on the market, especially among the multi-point locks also called multi-point locks, few are suitable for use by disabled persons with reduced mobility. It is not uncommon that locks are not accessible and / or easy to operate for these people. Adaptation of existing facilities can be complicated and costly.

There is therefore a real need for locks overcoming the defects, limitations, disadvantages and obstacles of the prior art, particularly with regard to the accessibility of homes to persons with reduced mobility and / or with different degrees of disability.

• un degré de sécurité élevé ;
• une accessibilité facile aux organes de verrouillage/déverrouillage ;
• un actionnement facile et efficace de la serrure ;
• des poignées faciles à saisir, qui peuvent être servies aussi par des personnes ayant peu de force ;
• une bonne tenue mécanique des mécanismes et organes de verrouillage/déverrouillage de la serrure ;
• une installation facile de la serrure permettant l'adaptation et/ou la construction d'habitation sans recourir à de travaux importants ;
• une installation sans surcoût particulier.

Thus, there is a real need for locks adapted to the homes of persons with reduced mobility and / or with different degrees of disability, offering at least one of the following characteristics:

• a high degree of security;
• easy accessibility to the locking / unlocking members;
• easy and effective operation of the lock;
• easy-grip handles that can also be used by people with little strength;
• good mechanical strength of the mechanisms and members for locking / unlocking the lock;
• easy installation of the lock allowing the adaptation and / or construction of housing without resorting to major work;
• a facility with no additional cost.

It is known from the document FR 2 931 186 multipoint mortise locks mounted in the edge of the door panels and including a handle in said projecting edge of the panel.

The present invention is specifically intended to meet these needs by providing a door panel having a latching side edge and a pivoting side edge, said door comprising a lock system for cooperating with said latching side edge, said system lock assembly comprising a multi-point lock secured in said latching side edge of said door panel, said multi-point lock comprising: a free-turn latch and a free dead bolt adapted to protrude from said latching side edge; at least one additional sentencing organ; a drive mechanism comprising a pinion and rack assembly for coupling said free dead bolt and said at least one complementary locking member; according to the invention, said lock system further comprises: an applied lock comprising a latch control latch actuable by a handle, and a control bolt actuated by a key cylinder, said latch mounted on said door panel in a position spaced from said multi-point lock; a first link and a second link for connecting respectively said control latch bolt and said free latch bolt, and secondly said control dead bolt and said free dead bolt; and in that said handle is intended to control the movement of the latch free half-turn, while said key cylinder is intended to control said free dead bolt and said at least one additional locking member.

Thus, a feature of the invention lies in the combination of the two types of locks: a multi-point lock constituting usual locking members and an applied lock to control it. While each of these locks taken independently may be insufficient, and especially poorly adapted to people with disabilities as adjusted in the locking edge of the door panel, the combination of the two types of locks provided a solution quite sufficient and satisfactory to the needs of disabled people, for example. This combination makes it possible to combine a multipoint lock already widely diffused to form the locking members and a commercial lock applied to form the control members of the multipoint lock. Thus, this allows at a lower cost, without any design effort, a new door panel suitable for disabled people.

For the lock system to play its role fully, it is that the applied lock is mounted on said door panel in a position spaced from said multi-point lock by at least 300 mm. It is also necessary that the lock applied has a handle, preferably easy to grasp, which actuates the bolt control half-turn.

According to a particularly advantageous feature of the invention, said drive mechanism further comprises operating rods for connecting said rack and pinion assembly and said at least one additional locking member. Indeed, and as will be explained below, the operating rods more precisely connect the racks and additional locking members adjusted respectively on either side of the drive mechanism in the vicinity of which are adjusted the bolt free turn and deadbolt. The additional locking members are fitted into the locking edge and away from the drive mechanism.

Another feature of the invention is the new and original position of the control device of the latches bolts and dormant free of the multipoint lock. Indeed, the applied lock which includes the latches latch and control frame, is mounted on said door panel remote from said locking edge and said multi-point lock. Thus, unlike conventional locks, in the lock system according to the invention, the control of the free latch and dead bolts of the multipoint lock is remote by the actuation of a handle and a key cylinder. . Also, the remote positioning of said control device, lock applied, provides an easy, economical and effective response to the needs of people with disabilities, especially when these people are in a wheelchair. Indeed, when they are carried with their armchair at the door panel, it is much easier to grab a handle or a key located towards the center of the panel rather than towards an edge. And once they've grabbed it, and powered it, they can naturally continue their wheelchair race by swiveling the door panel.

In addition, a door panel comprising a lock system according to the invention offers a high level of security. It allows a user with reduced mobility and / or attained different degrees of handicap, to lock or unlock easily and effectively a plurality of locking points manually and without requiring additional maneuver or increased effort to control them and / or operate said lock system.

In the context of the invention, the door panel can be installed in single leaf where it is double leaf. Advantageously, the door panel has two walls held at a distance from one another by spacer means. Thus, the multi-point lock is preferably a mortise lock and the applied lock is installed in the thickness of the door panel between the two walls. In this way, only the handle and the cylinder protrude from the walls.

The handle on the surface lock is intended to control the movement of the free latch bolt between an extended position protruding from said multi-point lock and said locking edge, and a retracted position within the multi-point lock. .

Said handle is fixed in such a way that it can only be used to actuate said control latch bolt, which in turn actuates, by a translational movement, said free latch bolt between an extended protruding position and a retracted position on the inside of the multipoint lock. The translational movement is transmitted to said free latch bolt by means of a first link. A return spring can cooperate with said first link to ensure said translational movement.

Said first link can be directly attached to the control latch bolt or on a metal plate, itself attached to said control latch bolt.

Said first link may comprise a cable, for example made of steel. Said cable may optionally be covered by a polyester film, or a nylon sheath, for example.

According to one embodiment of the invention, in addition to the cable, said first link comprises a spring at one of its ends. The said spring favors the return of said cable to its initial state after being requested. Said spring can be for example a helical spring.

According to another embodiment of the invention, when the control latch bolt is retracted only partially, for example at 50%, the free latch bolt is in a fully retracted position. However, in extended position, said two latch bolts are in fully extended position protruding from their respective lock.

As indicated above, the key cylinder present in the applied lock is intended to control said free dead bolt and said complementary locking members.

More particularly, said key cylinder functions to lock the free dead bolt and said additional locking members in the locked position.

Thus, said cylinder cooperates with said control dead bolt to actuate it. In turn, said control dead bolt drives, by a translational movement, said free dead bolt between a retracted position inside the multi-point lock and an extended position protruding from said multi-point lock. The translational movement is transmitted to said free dead bolt through the drive mechanism of the multipoint lock and by means of a second link.

Said second link may comprise for example an adjusting rod, preferably threaded. Said rod may be made of metal, for example steel. Said threaded adjustment rod is screwed into a threaded element. The threaded element is preferably a sleeve.

According to a particularly advantageous embodiment, the threaded rod and threaded element assembly cooperates with said control mechanism of said free dead bolt. Said drive mechanism comprises a pinion and rack assembly. Said rod and said threaded element meshes with the pinion, which pinion is inserted into the free dead bolt. Said pinion meshes with the racks of said drive mechanism.

Said racks being connected to the operating rods, their movement causes the movement in translation and in the opposite direction of said rods, which in turn cause the movement of the locking members complementary. This cooperation on several levels, has the effect of allowing the free dead bolt and said additional locking members to simultaneously set in locked position.

According to a particular embodiment of the invention, said multi-point lock advantageously comprises two additional locking members or bolts capable of being driven by two operating rods. Said operating rods are capable of moving parallel in a direction parallel to said locking edge. The movement of the operating rods causes a simultaneous movement and in translation of the locking bolts. Said locking bolts are capable of cooperating with latches arranged in concordance on the frame.

Said two links connecting the control bolts of the lock applies to the free bolts of the multipoint lock can work, regardless of the provision of said links. However, the operation of the lock system may be advantageous when the first link is parallel to the second link.

• La figure 3 est une vue schématique de détail d'un élément représenté sur la figure 2.

Other features and advantages of the invention will become apparent on reading the description given below of a particular embodiment of the invention, given by way of indication but not limitation, with reference to the accompanying drawings.

• The figure 1 is a schematic front view of a door panel according to the invention;
• The figure 2 is a schematic detail view of the door panel shown on the figure 1 ; and,
• The figure 3 is a schematic detail view of an element represented on the figure 2 .

The figure 1 illustrates a rigid wall 20 of a door panel according to the invention and having a lateral locking edge 22 and opposite a lateral pivoting edge 24. Said rigid wall 20 comprises a lock system 1 intended to cooperate, d on the one hand with said locking lateral edge 22 and on the other hand with the amount of the frame not shown.

The lock system 1 is fitted against the visible face in the drawing of the rigid wall 20, and to form the door panel according to the invention, there will be provided a second rigid wall not shown here, which will be applied against rigid wall shown to be made integral by providing a free space between the two walls. The lock system 1 will thus essentially be housed in the thickness of the door panel between the two rigid walls.

The lock system 1 comprises a multipoint lock 2 and an interlocked lock 3 which will be detailed respectively below. The multipoint lock 2 is a mortise lock and is installed in the thickness of the latching side edge 22 of the door panel according to the invention. She appears discovered on the figure 1 because the second rigid wall has not yet been applied and secured to the first rigid wall 20 so as to sandwich the multipoint lock 2. The latter comprises a central housing 26 installed in the locking side edge 22 half distance between the upper edge and the lower edge of the rigid wall 20 and two complementary boxes, one upper 28 installed near the upper edge of the rigid wall 20, the other lower 30 installed near the lower edge of the rigid wall 20 The central housing 26 has a free latch bolt 4 and a free dead bolt 5 extended projecting from the latching side edge 22 through a headrest 32. These bolts are obviously intended to engage in the strikes of the amount mentioned above when the door panel is in a closed position. The central housing 26 comprises inside, a driving mechanism 8 which will be detailed below with reference to the figure 2 . This drive mechanism is respectively connected to the complementary housings 28, 30 via an upper rod 34 and a lower rod 36. The upper rods 34 and lower 36 are installed longitudinally in the edge of the lateral border of 22 and they are respectively extend through the central housing 26 and the complementary housings 28, 30. The additional upper housing 28 and lower 30 respectively comprise a complementary dead bolt 6 constituting complementary locking members. These complementary dead bolts 6 extend projecting from the lateral edge of locking 22 substantially parallel to the free dead bolt 5. Also, the complementary boxes 28, 30 comprise a mechanism for returning the translational movement of the rods respectively, upper 34 and lower 36 to actuate the complementary dead bolts 6 in a movement perpendicular to the rods.

The wall-mounted lock 3 is installed at a distance from the locking lateral edge 22, behind the central housing 26 of the multipoint lock 2. It is for example installed at a distance of 350 mm from the locking lateral edge 22. The lock 3 comprises a control latch bolt 11 and a control dead bolt 13 projecting from a housing 38. The control latch bolt 11 is actuable by means of a handle 40, or crutch while the control dead bolt 13 is actuable by means of a key cylinder 14. In addition, the latch control bolt 11 is connected to the free latch bolt 4 by means of a first link 15 flexible, while the control dead bolt 13 is connected to the free dead bolt 5 by means of a second rigid link 16.

We will detail now with reference to the figure 2 the connection mode of the lock applies 3 and the multipoint lock 2 through its drive mechanism 8 which appears discovered in this figure. It includes the free dead bolt 5 and the free latch bolt 4 projecting from the central housing 26.

The latch free latch 4 has a first bolt tail 42 which extends transversely inside the central housing 26 and which terminates, by a perpendicular guide piece 44 translatable in translation between the two opposite walls of the central housing 26. In addition, the drive mechanism 8 has a return spring 46 bearing against this guide piece 44 to drive it towards the headrest 32 and thus hold the free latch bolt 4 projecting from the lateral edge of This guide piece 44 is directly connected to the control latch bolt 11 via the first flexible link. This first flexible link comprises a cable 48 which extends inside the central housing 26 to join the guide piece 44 and an outer sheath 50 which extends between the central housing 26 and the control latch bolt. 11. The latter is provided with a back plate 52 pierced to accommodate the cable 48. The latter has a stop member 54 which bears against the back plate 52, opposite the latch free latch 4. In this way, when the handle 40 is rotated, the control latch bolt 11 is driven in translation in a direction V opposite the headrest 32 and the locking lateral edge 22, and through the cable 48 and the guide piece 44, the latch bolt 4 is retracted inside the central housing 26. In this way, the latching side edge 22 is released from the jamb striker and the door panel can be pivotally driven provided that the free dead bolt 5 be retracted.

The free dead bolt 5 has a second bolt tail 56 extending the free dead bolt 5 inside the central housing 26. The second bolt tail 56 has an axial groove 58 opening opposite to the free dead bolt 5 and arranged on the opposite side to that which appears on the figure 2 . In addition, the bottom of the axial groove 58 has an axial recess 60 appearing in the figure. We will refer to the figure 3 to describe in more detail, the bolt shank 56. There is found the axial recess 60 opening into the axial groove 58. Furthermore, the upper edge 62 of the axial groove 58 has a not shown bolt rack, because hidden on the figure and in which meshes a pinion 64. The latter is engaged inside the axial groove 58, the teeth in the bolt rack, while its axis of rotation 66 projects from the axial recess 60. in this way, it is understood that the translational movement of the free dead bolt 5 towards the inside of the central casing 26 is able to cause the pinion 64 to be rotated by means of the bolt rack of the axial groove 58. Furthermore, will observe on the figure 3 that the pinion 64 also meshes in an upper rod rack 68 and opposite to its axis of rotation 66, in a lower rod rack 70. In this way, it is understood that the translational movement of the free dead bolt 5 towards the inside of the central housing 26 causes the pinion 64 to rotate clockwise and hence, in a substantially perpendicular direction, a pull on the upper and lower rod racks 68 and 70.

We will refer again to the figure 2 then showing the second rigid link 16 connecting the control dead bolt 13 and the bolt tail 56 and which makes it possible precisely to retract the free dead bolt 5 towards the inside of the central casing 26 by means of the key cylinder 14. second rigid link 16 comprises a threaded rod 72 integral at one end of the control dead bolt 13 and which is engaged at the other end thereof in a threaded sleeve 74. This threaded sleeve 74 is rotatably mounted in the bolt tail 56, but prisoner in translation. Thus, the rotation of the threaded sleeve 74 makes it possible to adjust the relative position of the free dead bolt 5 and the control dead bolt 13.

Furthermore, the upper rod rack 68 is integral in translation with the upper bead wire 34, while the lower bead rack 70 is integral with the lower bead wire 36.

So, again referring to the figure 1 it is understood that the actuation of the handle 40 causes the retraction of the free mid-turn bolt 4, and that it is more easily accessible for wheelchair users, when it is located towards the center of the door panel. In particular, when the wheelchair is positioned opposite the door panel, it is easier to actuate the handle 40 and to continue the race of the chair by pivoting the panel. of door. In addition, thanks to the key cylinder 14 of the applied lock 3, in the same way, the free dead bolt 5 and the two complementary dead bolts 6 are simultaneously controlled.

According to a particularly advantageous embodiment of the invention, the multi-point lock and the applied lock constitute a single block that can be inserted into the thickness of a door panel. Also, the distance between the drive mechanism of the multipoint lock and the surface lock is preset for the different application. They are also advantageously housed in one and the same housing.
