EP1707713B1 - Lock device for swinging door, window or French window - Google Patents

Abstract

The device has a tab (10) and an operating unit (9) that do not cooperate and are integrated to a lever-handle (8), and a pivoting unit locking unit with a locking wedge. A spring (11a) of the locking unit applies the locking wedge between two pivoting units (4, 5) for confining a mushroom rail (3) during the closing of a leaf (2). The pivoting units release the rail during the opening of the leaf.

With reference to Figures 1 to 8 identical or functionally equivalent elements are identified by identical reference numerals.

On the figure 1 , a frame 1 formed by assembling profiles cooperates with a flapper frame 2 made by assembling profiles, to ensure the closing or opening of a window, door or swinging French window.

The frame 1 permanently receives a conformation 3 mushroom cooperating with pivoting members 4 and 5 of the swing frame 2.

Preferably, the mushroom conformation 3 consists of a continuous rail-shaped section extending substantially over the entire height of the fixed frame 1.

Preferably, the pivoting members 4 and 5 are made of profiles each having an input chamfer able to rotate the member 4 or 5 corresponding under the action of conformation 3 fungus.

Each pivoting member 4 or 5 is mounted on a pivot axis preferably of material with the profile 4 or 5. Each pivot pin is mounted prisoner in a corresponding housing of the profile constituting the vertical amount of the frame 2.

A mechanism is mounted on the box or chest for locking and unlocking the device according to the invention, by actuating the barrel cylinder 7 or by operating the handle 8.

The sections of parts 3, 4 and 5 of the device according to the invention are similar to the sections of parts 3, 4 and 5 described in the patent application. French FR 04.06109 not published at the filing date of this application.

In this patent application French FR 04.06109 unpublished at the filing date of the present application, the conformation 3 in mushroom cooperates with the pivoting members 4 and 5 integral with a sliding frame, while the subject of the present application relates to a locking system for a door, window or swinging or pivoting French window: thus, the arrangement of the members 3, 4 and 5 is perpendicular to the leaf plane, and not parallel to the leaf plane as in the patent application French FR 04.06109 not published at the filing date of this application.

On the figure 2 , a trunk 6 or device according to the invention carries a crutch 8 and a locking cylinder 7.

A mechanical assembly is mounted on the trunk or block 6: this mechanical assembly has a locking piece 11, intended to lock in position the pivoting members 4 and 5, a block 12 for mounting the cylinder 7, a control 13, an axis 14 articulation of the blocking piece 11, a barrel barrel 7, an actuating groove 16 intended to be displaced by the bit 15 of the cylinder 7, and appropriate holding springs.

According to the invention, the handle 8 makes it possible to actuate an actuating element 9, whereas the locking piece 11 carries a member 10 able to slide between two positions to cooperate with the element 9 and to cause or not the rotation of the blocking element 11.

The actuating element 9 integral with the handle 8 preferably carries a curved or at least partially spherical end, and the cooperating element 10 preferably has a tongue-like conformation carrying an at least partially spherical portion intended to cooperate with the spherical portion. of the element 9 maneuvering.

When the two curved or at least partially spherical portions are in cooperation, the locking piece 11 is subjected to a pivoting action against springs 1 a, to release the members 4 and 5.

On the figure 3 , the stand 8 is in the rest position. The tongue 10 and the element 9 integral with the stand 8 do not cooperate, while the spring 11a applies the locking wedge B of the locking piece 11 between the pivoting members 4 and 5 to trap the rail 3 in the form of a mushroom. and lock the door.

On the figure 4 , the actuation of the stand 8 causes the cooperation of the ends or protuberances of the element 9 and the tongue 10. The tongue 10 pushed inward rotates the locking element 11 against the spring 11a for release the blocking wedge B and release the pivoting members 4 and 5, so as to allow them to pivot in the profiled post of the swing frame 2.

On the figure 5 , traction on the operating handle 8 causes pivoting of the pivoting members 4 and 5 and allows the opening of the wing 2. The actuation of the stand 8 remains maintained and the tongue 10 remains pushed inward while maintaining the locking element 11 against the spring 11a to disengage the locking corner B of the pivoting members 4 and 5.

On the figure 6 , the release of the stand 8 disengages the elements 9 and 10 and allows the pivoting of the locking piece 11 prestressed by the spring 11a. The locking wedge B is positioned against the rear ends of the actuating members 4 and 5, thus maintaining the members 4 and 5 in the spaced apart position.

On the figure 7 the beginning of closure of the flap 2 is effected by simple pushing. The input chamfers of the pivoting members 4 and 5 cooperate with the rail 3 mushroom to allow their alignment; then, continuing to drive the head of the mushroom in the pivoting members 4 and 5 causes their rotation, so as to trap the head of the mushroom between the pivoting members 4 and 5. The pivoting of the pivoting members 4 and 5 around their vertical axis releases a space allowing insertion of the blocking wedge B between the pivoting members 4 and 5, so as to return to the position shown and described with reference to FIG. figure 3 .

It is thus possible to slam the wing 2, so as to cause its automatic closing by insertion of the locking wedge prestressed by the spring 11a between the pivoting members 4 and 5; or, alternatively, one can close the leaf 2 smoothly by actuating the handle 8, so as to hold the locking wedge B before releasing the stand 8 to allow insertion of the locking wedge B between the pivoting members 4 and 5.

With reference to the figure 8 the operation of the device according to the invention will be described, using a key lock or unlocking.

An essential advantage of the invention is indeed to allow the use of the device in known manner, by taking over the usual functions of a lock, that is to say by opening the leaf 2 with the stand or handle 8 , or alternatively through the barrel cylinder 7.

When using the cylinder 7 to lock or unlock the wing 2, the cylinder blade 15 pushes the groove 16 to release the control 13 and allow the vertical translation of this command.

The vertically sliding element 10 is in turn driven vertically by the control 13, so that its protruding end comes into contact with the cooperating form of the element 9 integral with the stand 8, so as to rotate the element of blocking 11 around the axis 14 and so as to release the wedge B blocking thus allowing pivoting of the pivoting members 4 and 5.

The position of the tongue 10 thus defines the state of the lock.

In fully retracted position, or low position, the action on the handle 8 does not cause cooperation between the element 9 and the tongue 10, so that the leaf 2 remains locked due to the blocking of the corner B between the pivoting members 4 and 5 trapping the rail 3 mushroom.

When the tongue 10 is in the intermediate position, the action on the handle 8 causes the cooperation of the elements 9 and 10 and the pivoting of the blocking part 11, thus unlocking the leaf 2.

When the tongue 10 is moved by means of the bit 15 in the high position, it cooperates by contact with the element 9 and causes the pivoting of the locking piece 11, so that the pivoting members 4 and 5 are released, thus allowing the opening of the door. This mode of operation is generally called by the specialists "return of the half turn to the key", by analogy with the operation of unlocking a latch bolt by means of a key in locks of known type.

The invention described with reference to a particular embodiment is not limited thereto, but on the contrary covers any modification of form and any variant embodiment within the scope and spirit of the invention.

Thus, the elements 9 and 10 of cooperation may adopt any other shape ensuring the pivoting of the locking piece 11 against a return spring 11a. In particular, the elements 9 and 10 may have corner protrusions or prism rounded apex, or any other similar form. Similarly, the displacement of the elements 9 and 10 can be achieved by combining two translations, a rotation and a translation, or two rotations.
