Description

The invention relates to a multi-point anti-panic lock central housing, of the type which includes an operating lever articulated on a transverse axis, and a mechanism, controlled by the lever, suitable for driving, in opposite direction, two rods located on either side of the housing and intended to be vertical when the lock is in place on a door, each rod being provided at its end remote from the housing with a bolt to establish a locking respectively at a high point and at a low point, the operating lever comprising a unilateral abutment member capable of cooperating with one of the two complementary abutments for driving the mechanism.

Such a multi-point panic lock central housing is, for example, described in US-A-1 345 041. This housing according to US-A-1 345 041 is arranged so that, regardless of the direction in which the lever is operated , up or down, the two rods are operated in opposite directions; this is obtained by the fact that the two complementary stops, with which the lever cooperates for driving the mechanism, are one secured to a rod and the other secured to the other rod; furthermore, the mechanism described in this document is not symmetrical.

We know that a door can be of the "right" or "left" type depending on whether the hinges are located on one side or the other of the door.

The central boxes of multi-point panic locks are generally of two types corresponding to each type of door. This is the case according to US-A-1 345 041. It follows that it is necessary to store two types of cases, which complicates the work. The installer of a lock can be presented with a housing which is not suitable for the door on which it is to be mounted, which generates a waste of time. In addition, this existence of two types of boxes, corresponding to the two types of doors, is a source of errors, in particular when ordering and delivering parts.

The object of the invention is, above all, to provide a median box for a multipoint anti-panic lock of the kind defined above which has more, or to a lesser degree, the disadvantages mentioned above. It is further desirable that such a central housing is of a relatively economical construction and can be adapted, by a simple and rapid operation, as well to a door "on the right" as a door "on the left".

According to the invention, a multi-point anti-panic lock central housing, of the type defined above, is characterized in that the two complementary stops are provided on a drive member of the mechanism and angularly spaced, the lever being able to be tilted from a position to another to cooperate with the appropriate complementary stop in order to allow indifferent mounting on a door type "right" or "left", while the mechanism suitable for driving the rods is arranged symmetrically so that the housing is completely reversible.

The unilateral abutment member of the lever can be constituted by a pin while said driving member is constituted by a plate substantially orthogonal to the axis of the lever, the complementary abutment members being constituted by the ends of an arc light circle, centered on the axis of rotation of the lever, and provided in said plate. This plate may be of substantially rectangular shape and be freely articulated on the axis of the lever towards one of its vertices, said plate cooperating, in contrast, with a rod control device, while said light in a circular arc has its ends located near the vertices of the other diagonal.

Advantageously, the driving member is located in the mean longitudinal plane of the housing and is provided, on the side opposite to the articulation axis of the lever, pushing means projecting on either side of the driving member to cooperate, in the direction of rotation of the driver, with one of two identical parts mounted in opposite directions for controlling the rods.

Preferably, the above identical parts are slidably mounted in the housing and comprise a part having substantially the same width as the housing, part to which is connected one end of a rod, this part comprising an extension, towards the other part, of width slightly less than half the width of the housing, this extension being adjacent to one face of the housing, the driving member being located between the two extensions.

A rotating part is mounted inside the housing, so as to pivot about an axis orthogonal to the bottom of the housing against which the above-mentioned rod control parts slide, this rotating part being suitable for transmitting, by reversing it, movement from one rod to another.

According to a first possibility, the rotating part, of substantially rectangular shape comprises, on two opposite sides, a notch open towards the outside suitable for cooperating with a lug provided under each sliding part of which it is integral.

Preferably, each extension comprises at its end remote from the associated rod, a shoulder capable of being driven by the lever pushing means formed by a pin.

Advantageously, said shoulder comprises a transverse wing on which is hooked one end of a return spring whose other end is attached to a lug secured to said housing.

Each extension preferably comprises an elongated opening crossed by the lug.

According to another possibility, the rotating part is linked, at each of its ends, by a joint, in particular formed by a pin, with the extension of one of the sliding parts, said parts being mounted in the housing with a possibility of oscillation.

Advantageously, the housing comprises a single torsion spring, centered on the axis of rotation of the rotating part, capable of returning this part to the rest position, in particular by action on an articulation pin between the rotating part and the extension d 'a sliding piece.

The pushing means may comprise two legs spaced angularly and located on either side of the mean plane of the driving member.

The invention also relates to a multi-point panic lock comprising a median box as defined above

Referring to FIG. 1, one can see a door 1 with two leaves 2, 3 fitted, on their vertical outer edges, with hinges 4, 5 respectively.

The leaf 3, located on the right-hand side of FIG. 1, is equipped with a multipoint panic lock 6 comprising a median box 7. The lock 6 can be controlled, from inside the building, by action on a horizontal bar B carried , at its end situated on the side of the housing 7, by a lever 8 articulated in this housing and, at its other end, by a lever articulated in another housing 9 fixed on the door.

The central housing 7 is mounted adjacent to a central strike 10̸ fixed on the edge of the leaf 3 adjacent to the leaf 2. This strike 10̸ is intended to receive a transverse bolt 11 from another panic lock 12 mounted on the leaf 2.

As can be seen in FIG. 2, the lever 8 of the multi-point panic lock 6 is articulated on a transverse axis 13. The housing 7 is constituted by a U-shaped profile whose concavity is turned on the side opposite to the leaf 3 and whose wings are arranged vertically. The tops of these wings were cut in an inclined direction giving a trapezoidal shape at the part of the wings 14 furthest from the leaf 3. The bottom 15 of the housing, connecting the wings 14, is applied and fixed against the leaf 3.

The transverse axis 13 is carried by the two wings 14, towards their edge remote from the bottom 15.

The housing 7 comprises a mechanism 16, controlled by the lever 8, capable of driving, in the opposite direction, two rods 17, 18 located on either side of the housing 7, in the extension of one another. These rods 17, 18 are intended to be vertical (see Figure 1) when the lock is in place on the leaf 3 of the door 1. Each rod 17, 18 is provided, at its end remote from the housing 7, with a latch p to establish a lock at a high and low point respectively.

The operating lever 8 comprises, at its end lying between the wings 14, a unitary abutment member 19 constituted by a pin 20̸ orthogonal to the mean plane of the lever 8, and to the plane of the wings 14.

The pin 20̸ is suitable for cooperating with one of two complementary stops 21, 22, angularly spaced and provided on a driving member 23.

The stop members 21, 22 are formed by the ends of a slot 24 in an arc centered on the axis 13 of the lever.

The driving member 23 is constituted by a plate of substantially rectangular shape whose apex is freely articulated on the axis 13 of the lever and the opposite apex of which is crossed by a pusher 25, formed by a pin, orthogonal to the mean plane of the 'organ 23 and projecting from either side of this organ. This pusher 25 is suitable for cooperating with a device 26 for controlling the rods 17, 18. The light 24 has its ends 21, 22 located in the vicinity of the vertices of the other diagonal of organ 23.

The driver 23 is located in the mean longitudinal plane of the housing 7 and its pusher 25 is provided to cooperate, in the direction of rotation of the driver 23, with one of the two identical parts 27 a , 27 b mounted in the opposite direction reverse for the control of the rods 17, 18.

Each part 27 a , 27 b is slidably mounted in the housing 7 against the bottom 15 of the latter. The part 27 b is described in detail below, in particular with reference to FIG. 7. The same description applies to the part 27 a , the similar parts of which are designated by the same reference numerals assigned with the letter a instead of the letter b .

The part 27 b comprises, at one end, a part 28 b , in the form of a rectangular plate, having the same width as the internal width of the housing 7 so as to be guided by the internal faces of the wings 14. This plate 28 b comprises , on its edge facing the rod 18, in its median region, an extension provided with a fork 29 b situated in a transverse plane orthogonal to the plane of the plate 28 b . This fork 29 b has a central notch open upwards suitable for receiving, between its wings, the bottom of a groove 30̸ b formed at the end of the rod 18. The branches of the fork 29 b are thus trapped, according to the sliding direction of the rod 18, between the walls delimiting the groove 30̸ b , which establishes a connection in translation between the part 27 b and the rod 18.

The plate 28 b comprises, in the direction of the other part 27 a , an extension 31 b adjacent to an internal face of a wing 14 of the housing and whose width l is slightly less than half the internal width L (FIG. 3) of the housing.

Because the two parts 27 a , 27 b are turned in opposite directions, each extension 31 a , 31 b (see FIG. 3) is adjacent to a different wing of the housing so that a free space exists between the neighboring edges of the extensions 31 a and 31 b . The drive member 23 passes through this space.

The extension 31 b comprises, at its end remote from the fork 29 b and from the associated rod 18, a shoulder 32 b whose plane is orthogonal to the plate 28 b , while being parallel to the longitudinal direction of the extension 31 b , as well as to the wings 14. The pusher 25 of the driver 23 is able to cooperate with the vertical edge 33 b of the shoulder 32 b .

The extension 31 b also comprises a transverse wing 34 b orthogonal to the shoulder 32 b and to the mean plane of the extension 31 b . This wing 34 b has a hole 35 b for hooking the end of a return spring 36 b , the other end of which is hooked to a lug 37 b secured to the bottom 15 of the housing. The lug 37 b , perpendicular to the bottom 15, passes through an elongated opening 38 b provided in the extension 31 b so as to guide the movement in translation of the part 27 b .

As clearly visible in FIGS. 2 and 5, the extension 31b has its mean plane offset relative to the mean plane of the plate 28b , so as to be spaced from the bottom 15; a bent portion 39 b ensures the transition between the plate 28 b and the extension 31 b .

A rotating part 40 is disposed in the space between the extensions 31a, 31b and the base 15. This part 40 is rotatably mounted about an axis 41 orthogonal to the base 15, midway between wings 14 and plumb with axis 13.

The part 40̸ is constituted by a sort of plate with a substantially rectangular outline, with vertices rounded, the dimensions of which are such that said plate can rotate between the wings 14. The component 40 comprises, in the middle of each of its short sides, a notch 42 a, 42 b open to the outside, adapted to receive a lug 43 a , 43 b projecting under the associated extension 31 a , 31 b .

The part 40̸ is suitable for transmitting, by reversing it, the movement of a rod 17 to the other rod 18 or vice versa.

The parts 27 a , 27 b are symmetrical with respect to the center of rotation of the part 40̸.

However, the operation of the housing 7 and the panic lock comprising such a housing are as follows.

The lever 8 in the rest position is inclined, relative to the bottom 15, so that the pin 20 le is in abutment against the end 21 or the end 22 of the slot 24.

In the rest position shown in Figure 2, the pin 20̸ is in abutment against the end 21 of the light 24, which corresponds to a type of door, for example a door type "left".

If this box 7 is to be mounted on a door of the "right" type, it suffices to pivot the lever 8, around the axis 13, anticlockwise, as shown in FIGS. 2 and 5, so as to bring the pin 20̸ into abutment against the other end 22 of the light 24.

It therefore appears that the adaptation of the lock housing to a door of the "right" type or of the "left" type is immediate, using a simple operation and not requiring specific tools.

The operation of the lock, whatever the rest position of the lever 8, is the same and will be described for the position of the lever 8 shown in figure 2.

By acting on the control bar (see Figure 1), the lever is rotated clockwise as shown in Figure 2. The pin 20̸ acts against the stop 21 and causes the displacement of the 'coach 23 clockwise around axis 13.

The pusher 25 acts against the edge 33 b and moves the part 27 b against the spring 36 b . The rod 18 is pulled into the housing 7 and the bolt located at the lower end of the rod 18 (see Figure 1) is unlocked.

Simultaneously, the rotating part 40 is rotated by the lug 43 b in the direction of counterclockwise (according to the representation of Figure 3) about the axis 41.

The configuration of the housing, when the lever 8 is depressed, is shown respectively in FIGS. 5 and 6. The rotating part 40̸, controlled by the movement of the part 27 b , causes the translation in the opposite direction of the part 27 a and therefore the displacement of the rod 17 whose upper bolt is also unlocked.

When the lever 8 is released, the springs 36 a , 36 b recall the parts 27 a , 27 b towards the closed position. The section 33 b acts on the pusher 25 and recalls the driver 23 as well as the lever 8 in the rest position shown in FIG. 2.

Referring to Figures 8 to 10̸, we can see an alternative embodiment of the panic lock housing according to the invention.

In this variant, the elements identical or playing roles analogous to elements already described in connection with the preceding figures bear the same references increased by the number 10̸0̸ and their description will not be repeated or will be resumed only succinctly.

The rotating part 140̸, of elongated rectangular shape, is linked, at each of its ends, by a joint, in particular formed by a pin 143 a , 143 b , with corresponding extension 131 a , 131 b of the sliding parts 127 a , 127 b . This connection, which simplifies the production, causes a rotational movement around the axis 141 of the ends of the extensions 131 a , 131 b .

Under these conditions, the sliding parts 127 a , 127 b are mounted with the possibility of oscillation inside the housing 10̸7. In particular, the parts 128 a , 128 b have rounded edges 44 a , 44 b in contact with the internal walls of the housing 10̸7 to ensure guidance of the oscillation.

These parts 128 a , 128 b are extended by zones of smaller width, so that a clearance j exists between the edges of these zones and the internal surface of the housing.

A single torsion spring 136, comprising a winding in which the axis 141 is threaded, is provided to return the part 140̸ and the rods 117, 118 in the rest position. A branch 45 of this spring, bent at a right angle, bears against an internal wall of the housing 10̸7; another branch 46 of the spring recalls the part 140̸ by pressing against the pin 143 b .

The part 140̸ is thus urged in the clockwise direction, according to the representation of FIG. 9, by this spring 136.

The pushing means 125 are advantageously formed by two tabs 125 a , 125 b cut from the plate 123, angularly spaced from one another and folded down on either side of the mean plane of the driving member 123. These parts 125 a , 125 b frame the pins 143 a , 143 b and are capable of acting against these pins to ensure the drive of the mechanism by the 'through the lever 10̸8 and the member 123.

Thus, according to this variant, the pusher 25 of Figures 2 to 7 is replaced by the legs 125 a , 125 b . The plates 127 a , 127 b no longer have elongated lights such as 38 a , 38 b (see FIG. 3).

A single torsion spring replaces two tension springs.

The pins 43 a , 43 b of Figures 2 to 6, are replaced by the pins 143 a , 143 b , while the pins 37 a , 37 b , integral with the bottom of the housing in Figures 2 to 6, have disappeared from the variant of Figures 8 to 10̸.

Two axes 47, 48, fixed between the internal walls of the housing 10̸7, are provided, parallel to the axis 113, in the vicinity of the bottom of the housing so as to retain the plates 127 a , 127 b .

The operation of this alternative embodiment is similar to that described in connection with FIGS. 2 to 7 and it does not appear useful to describe it again.
