Description

IMPROVED LOCKING AND UNLOCKING DEVICE

FROM A DOOR

BACKGROUND OF THE INVENTION

The present invention relates to a device for locking and unlocking a door, of the type comprising a European cylinder whose operation by means of a key controls the rotation of a gear, which rotation in turn controls the vertical displacement by sliding of at least one zipper which is provided with a vertical rack and which is integrated into the bottom of a housing disposed behind the door, said housing being itself constituted by a trunk and a hood removable allowing access to all mobile and fixed organs of the device.

In the devices of the above-mentioned type currently marketed, which most frequently comprise two drawbars, the pull tab or each of the two drawbars has at least one elongate, inclined light on the vertical, which receives a finger emerging from a so-called dead bolt so that, when sliding the zipper up or down, the deadbolt is itself driven in a horizontal movement backwards or forwards respectively corresponding to its retraction / extraction relative to the housing, each light of each pull being tilted back and forth in the direction of its distance relative to the barrel, said device further comprising a free bolt whose horizontal displacement to the rear or to the front is controlled by an operating knob placed at the outside of the case.

In such known devices, responding to the technical particularities and detailed, it is possible, from outside the premises to be closed with the doors equipped with said devices, to maneuver the dead bolts by turning the key corresponding to the European barrel sp c of each device, but there is currently no other known solution to maneuver their free bolt than that of using very important cinematic chains, therefore expensive and unavoidable sources of breakdowns. There is thus an obvious interest in reducing or even eliminating these complex kinematic chains.

GENERAL DESCRIPTION OF THE INVENTION

The present invention provides precisely a response to such a need by removing any driveline in the maneuver of the free bolt.

The present invention thus relates to a locking and unlocking device of the aforementioned type, remarkable in that the pull or that of the two drawbars which, during its sliding, engages under the free bolt has an inclined cut of the forward towards the rear in the direction of its distance relative to the barrel, in that the inclined edge of said cutout is adapted to cooperate with a finger emerging from the free bolt towards the bottom of the housing and in that each inclined light of the the zipper concerned or, according to, each of the two drawbars is extended by a vertical light which originates from that of the two ends of the inclined light which is farthest from the barrel. Preferably, such a device is also remarkable in that it comprises two drawbars each having a vertical rack, namely an upper puller and a lower puller meshing respectively to the right and left of the gear, in that the European barrel is disposed below the free bolt and in that the zipper having the inclined cutout is the upper pull.

The improved device according to the invention may also have one or more of the following features: the angle of each zipper is inclined vertically at an angle between 10 ° and 20 °, and preferably equal to about 15 °, the cut is inclined to the vertical by an angle between 30 ° and 50 °, and preferably equal to about 40 °,

each zipper has as many vertically inclined and extended lights as are desired deadbolts, that is to say fixing points,

- The free bolt is permanently pushed forward by a leaf spring disposed outside the trunk between the trunk and the removable cover,

- The operating knob of the free bolt is disposed at the end of an axis whose other end is provided with a stop which passes through a notch made in the lower face of the free bolt, that is to say the face in look from the bottom of the chest,

- The bottom of the trunk has a welded angle on its entire height, one wing of which constitutes a guide or lateral stop for the one or both drawbars, and

- The chest is an inverted Ω section section whose two wings are crossed by the deadbolts and the free bolt and the cover is a U-section section which covers the strike of the lock.

According to a particularly interesting construction, the European barrel is, for its half outside the housing, embedded in a cuirass which is fixed to said device with the aid of at least two assembly screws which pass through a plate disposed at the bottom of the trunk and are screwed into said cuirass.

In this latter construction, advantageously, the axis at the end of which is mounted the operating knob of the free bolt through a bearing whose base is screwed into the plate and whose upper end is provided with a collar of s' apply to the clean plate covering the outer face of the core of the cover, thus allowing the assembly of said cap, the operating knob being assembled by screws on the upper end of the emerging axis of the bearing. Also preferably, in this construction, a screw passes through the lateral face of the bonnet and the flange of the guide angle and penetrates the bearing, thus assembling the plate on the bearing and making it henceforth impossible any rotation of the bearing as well as the dismantling of the lock when the door is locked.

The device according to the invention may finally advantageously provide that the upper puller and the lower pull tab comprise at their free end a bracket for receiving a vertical bolt.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

The improved device according to the invention for locking and unlocking a door which will be described hereinafter is of the type comprising, in a known manner, a European cylinder 1 whose operation with the aid of a key integrated in one of the two orifices 2 of the barrel controls the rotation of a gear 3, for example a gear of ten teeth of module 2 or a gear of fourteen teeth of module 1.5. The rotation of said gear in turn controls the vertical displacement by sliding of at least one pull tab 4 formed in a thin plate, and preferably of two drawbars, which are each provided with a vertical rack 5. In the illustrated example, the gear 3 cooperates with two vertical racks 5a and 5b respectively, each formed in a pull-tab, respectively the upper or upper pull tab 4a, which slides essentially above the European cylinder, and the lower or lower pull bar 4b which essentially slides below the European barrel.

Each zipper 4 is integrated into the bottom of a housing disposed behind the door, consisting of a trunk 6 and a removable cover 7 allowing access to all of the movable and fixed members of the device arranged inside. of said housing.

In the example shown, the trunk 6 is an inverted Ω section section and the cover 7 is a U-section section whose wing covers the latch of the lock.

Still in a known manner, the pull tab, or each of the two drawbars 4a, 4b in the illustrated example, has at least one elongated light 8 which is inclined to the vertical and which receives a finger 9 emerging from a bolt 10 said dead bolt.

Each zipper has as many inclined lights as you want deadbolts 10, that is to say points of attachment.

In the illustrated example, the device being observed from inside the room to be closed using the door it equips, the operation of the European cylinder 1 with its key and, therefore, the rotation its gear 3 causes the displacement of the right rack 5a and thus the sliding of the upper puller 4a upwards or downwards, and this rotation simultaneously causes the displacement of the left rack 5b in a direction opposite to the previous one and therefore the sliding the lower pull tab 4b downwards or upwards respectively.

Each dead bolt 10, thanks to its finger 9 which then slides in a slot 8, is thus itself driven in a horizontal movement backwards or forwards respectively corresponding to its retraction / partial extraction relative to the housing.

For this, each light 8 of each zipper 4 is inclined forwards and backwards in the direction 14 of its distance relative to the barrel 1, here being specified that the front is the part of the housing through which the dormant bolts 10 emerge to form fixing points.

The device according to the invention also comprises a free bolt 11 whose horizontal movement, towards the rear or towards the front, is controlled from inside the room to be equipped by the rotation of a maneuvering knob 12 placed at the door. outside the case.

In the devices of the aforementioned kind currently marketed, the operation of the free bolt 11 with the 12 button always involves the use of a complex kinematic chain. According to the invention, which overcomes this disadvantage, the following remarkable adaptations are provided: a) the turret or that 4a of the two drawbars 4a, 4b which, when sliding, engages under the free bolt 11 has a cutout 13 inclined from front to rear in the direction, marked by the arrow 14, its distance relative to the barrel 1, b) the inclined edge 15 of the blank 13 is adapted to cooperate with a finger 16 which emerges from the free bolt 11 towards the bottom of the housing, that is to say in the direction of the bottom of the trunk 6, and c) each inclined light 8 of the zipper 4a concerned or, according to each of the two drawbars 4a, 4b, is extended by a vertical light 17 which originates from that of the two ends of the light The combination of these three constructions, the vertical displacement by sliding down the upper puller 4a, controlled by the gear 3 via the rack 5a, can also control the displacement. horizontal free bolt 1 1 towards the rear, in the direction of its opening, while the deadbolts 10, which were previously driven backwards, in the direction of their opening, always using the zipper 4a or zippers 4a , 4b, remain stationary in said open position because their fingers 9 then slide in the vertical lights 17 which extend the lights 8.

In other words, the construction of any light, first inclined 8 and then vertical 17, allows by its inclined part the forward movement and the rearward movement of each dead bolt 10 and, by its vertical part, the rear movement of the free bolt 11, that is to say, the turn of the lock.

Thus, the free bolt 11 is not only maneuverable from inside the room to be protected by the operating knob 12, but it can also be moved backwards, in the direction of its opening, by the rotation of an additional hour turn of the key using the upper pull tab 4a which has the cutout 13 and the inclined edge 15. In this case, the flange 4a engages under the free bolt 11, between the latter and the bottom of the trunk 6, and pushes back the finger 16 secured to the free bolt 11.

So that the free bolt then returns to the closed position, it is sufficient to turn the key of h turn in the opposite direction, which has the effect of raising the pull tab 4a, so to release the finger 16 of the free bolt 11, which is then automatically pushed back elastically as it will be described. Advantageously, the light 8 of each pull tab 4a, 4b is inclined vertically at an angle of between 10 ° and 20 °, and preferably equal to about 15 °, and the cutout 13 is inclined in the same direction on the vertical that the light 8 at an angle between 30 ° and 50 °, preferably equal to about 40 °.

Still advantageously, all the deadbolts 10 and the free bolt 11 pass through each of the two wings 35, 36 of the box 6 profiled in Ω so that their forward and backward movements are perfectly free. The free bolt is constantly pushed towards the front by a leaf spring 18 disposed outside the trunk 6, between said box and the removable cover 7.

In the example illustrated, the improved device according to the invention comprises two drawbars each having a vertical rack, namely the upper pull tab 4a and the lower pull tab 4b meshing respectively to the right and left of the gear 3, and the European barrel 1 is disposed below the free bolt 11, that of the two drawbars which has the inclined cutout 13 then being in this example the high pull 4a.

It has been seen that the free bolt 11 can also be maneuvered using a maneuver knob 12, said turn H button, disposed inside the premises to be protected.

To this end, the operating knob 12 is disposed at the end of an axis 19 whose other end is provided with a cleat 20 which crosses the notch 21 made in the lower face of the free bolt 11, that is to say in the face which is located opposite the bottom of the trunk 6.

It is understood that the rotation of the operating knob 12, that of the axis 19, controls via the cleat 20 flapping in the notch 21 the movement of back and forth, both left and right, the free bolt 11.

In order to guide the pull tab or the two drawbars 4a, 4b by constituting for them a lateral stop, provision is made in the bottom of the box 6 an angle whose one of the wings 22a is welded to the bottom of the box 6 and the other wing 22b, perpendicular to the wing 22a, constitutes the aforementioned guide.

However, in an even more simplified embodiment, it is expected that the width of the or each pull is equal to the useful width of the box, that is to say equal to the distance separating the faces vis-à- screws of the two wings 35, 36 of the trunk 6. Thus, it is these two wings 35, 36 which guide the pull or, according to the two drawbars 4a, 4b during each of their vertical movements. The European barrel 1 is, for its half outside the case 6-7, embedded in a cuirass 23 which passes through the door 30 of the room to be protected and which is fixed to the device according to the invention using at least two screws assembly of axes 24 which pass through a plate 25 disposed at the bottom of the trunk 6 and which are screwed into said armor 23.

The plate 25 has the shape of a Ω returned, its top resting against the bottom of the trunk 6 and its two lateral wings covering the racks 5a and 5b which can thus slide freely under them. The shaft 19 at the end of which is mounted the knob 12 passes through a bearing 26 whose base 27 is screwed into the plate 25 and whose upper end is provided with a collar 28 which is applied on the plate cleanliness or lining 31 which covers the outer face of the core of the cover 7 to the right of the opening of the barrel 1, thus allowing assembly of said bonnet, the operating knob 12 is then screwed at 34 on the upper extremal portion of the axis 19 emerging from the bearing 26.

Ideally, a screw 29 passes through the side of the trunk

6 and the wing 22b of the guide angle of the drawbars 4a, 4b then enters the plate 25 and finally the bearing 26 to the right of its threaded base 27, thus preventing any rotation of the bearing, assembling the plate on the bearing and making it impossible to disassembly of the lock when the door is locked since then the head of the screw 29 is inaccessible under the hood 7.

Finally, it is possible to provide at the free end of the upper pull tab 4a and / or at the free end of the lower pull tab 4b a bracket 32 pierced with an orifice 33 adapted to receive a vertical bolt constituting an additional fixing point.

It is also possible for each pull tab 4a, 4b as many lights 8, 17 that it is necessary to have fixing points and, for example, it has been shown in FIG. 7 an upper pull tab 4a and a lower pull tab 4b which are each provided with two pairs of lights 8, 17, which corresponds to a total of four lateral attachment points for the door. The movements of the drawbars upwards and downwards being very short, it is even possible to obtain fixing lateral points at 15 centimeters from the bottom and, respectively, from the top of the door by the prediction of two pairs, or even three and even more lights 8, 17 on each of the two drawbars.

It is obvious that, by construction, it is also possible to make a device of the type described above that is reversible, that is to say that can indifferently adapt to a door on which the lock is performed at right or left of it. For this, simply provide an arrangement of additional perforations in the bottom and in the wings 35, 36 of the trunk 6 in Ω. Thus, in particular, it will provide in the bottom of said chest two orifices for the ar and 1, four orifices for the passage of the axis screws 24 which assemble the plate 25, two orifices for the axis 19, and, in the same spirit, in the wings 35 and 36 of the trunk, provide two additional holes for the passage of the free bolt 11 and an additional hole for the passage of the fixing screw 29 to prevent disassembly of the bearing 26 when the lock is locked.
