Description

The invention relates to a device with several locking points, for sectional opening.

The invention is particularly useful for locking a sectional garage door gate, a flap gate opening wide, or any other sectional opening likely to articulate when it opens.

There are known devices with several locking points for metal joinery. This type of device has a locking block for each locking point. This locking block can be inserted and mounted in a cutting of the metal joinery by means of a headrest. The locking blocks are generally interconnected by at least one actuating blade sliding in the plane of the headrest. The headrest may advantageously be cut or indented to allow the sliding of the actuating blade, whose ends are then mounted to slide relative to the inside of U-shaped formations formed in the headrest. This device of known type is satisfactory, but can not be used for locking a sectional opening. A device according to the preamble of claim 1 is for example known from the document BE 528030 A . The invention aims to improve the known technique, providing a new device used for locking a sectional opening, both in the open position in the closed position of the opening.

The subject of the invention is a device with several locking points, in particular for a sectional opening, of the type comprising a central locking member, for example a lock, and at least one actuating blade of a locking point, central locking member being able to control the displacement of the at least one blade, characterized in that each actuating blade is interrupted by at least two portions successively connected by a double-joint connecting member, so as to allow the articulation of the sections of the opening at least in the open position and in the closed position of the opening such that the connection with double articulation simultaneously allows the articulation of the sections of the opening as well as its locking and unlocking. According to other alternative features of the invention:

• the spacing of the joints of the double articulation of the connecting member substantially corresponds to the stroke of the actuating member.
• the joints of the double articulation are preferably substantially coplanar with the articulation of the sections or panels of the opening, when these sections or panels are aligned.
• the double-joint connecting member may constitute an intermediate connecting rod in aligned position of the sections or panels of the opening, and an intermediate connecting rod hinge position articulated sections or panels of the opening.
• the double-joint connecting member may be shaped as a spacer with two force transmission surfaces adapted to cooperate with corresponding surfaces of the actuating blade portions.
• the coincidence of the axis of the articulation hinge sections or panels of the opening and an articulation of the connecting member is advantageously obtained in the hinge position of the opening, when these sections or panels are aligned and when the leaf is in the locking or unlocking position.

The invention will be better understood from the following description given by way of nonlimiting example with reference to the accompanying drawings in which:

• The Figure 1 schematically represents a side view of an opening with aligned panels, equipped with a device according to the invention in the locking position.
• The figure 2 schematically represents a side view of an opening with articulated panels, equipped with a device according to the invention in the locking position.
• The Figure 3 schematically represents a side view of an opening with articulated panels, equipped with a device according to the invention in the unlocked position.
• The figure 4 schematically represents a side view of an opening with articulated panels, equipped with a device according to the invention in the intermediate position.

With reference to Figures 1 to 4 identical or functionally equivalent elements are identified by identical reference numerals.

On the figure 1 , a device according to the invention comprises a central locking member 1, for example a lock, adapted to control the displacement of an actuating blade 2 connected to a block 3 of conviction.

The central locking member 1, in the case of a lock, comprises, in a manner known per se, a central box containing a mechanism and two locking bolts: a latch bolt and a rectangular bolt.

The actuating blade 2 is connected, in a manner known per se, to a return or actuator of the central trunk by one or more screws not shown.

The blade 2 of actuation can be maintained, in a manner known per se, by one or more jumpers against the edge of one or more panels A, B opening or gate.

These panels A, B opening or gate may be articulated to each other around a geometric axis 12 articulation, for example by means of a hinge.

The blade 2 is interrupted by a first portion 4a and a second portion 4b, interconnected by a connecting member 5.

The connecting member 5 is a double-joint member: a first hinge 6a with the first portion 4a and a second hinge 6b with the second portion 4b.

The portions 4a and 4b are secured to the ends of the actuating blade 2 permanently, for example by means of rivets 7.

In the position of the figure 1 , the transmission of the locking force is advantageously effected by the relative support of a plurality of force transmission surfaces: a first surface 8a limiting the portion 4a, a second surface 8b limiting the upper end of the member 5 connecting a third surface 8c limiting the lower end of the connecting member 5, and a fourth surface 8d limiting the portion 4b.

This arrangement has the advantage of operating the connecting member 5 in the manner of a spacer for transmitting the locking force exerted by the lock 1 on the blade 2 of actuation.

On the figure 2 , the sectional opening shown in articulated position has a first section or panel A and a second section or panel B. The relative articulation of the sections or panels A, B is obtained by means of a hinge fixed by tabs 10 , Respectively to the inner surfaces of panels A, B.

The geometric axis 12 of the hinge is merged in the position of the figure 2 with the geometric axis of the articulation 6a of the connecting member 5.

This position corresponds to the locking of the opening in an articulated assembly, because the actuating blade is in the lower position, corresponding to the descent of the joint 6b along the panel B.

In this position, the surfaces 8a and 8b form an angle between them, while the surfaces 8c and 8d remain contiguous to each other, even in the hinge position.

To obtain the coincidence of the axis of the hinge of the panels A, B and the axis of the hinge 6a, it is advantageous to provide by construction the placement of the hinges 6a, 6b and the hinge joint in a same plan.

On the figure 3 , the opening comprising the two articulated panels A, B is in the unlocked position, this position corresponding to the coincidence of the axis 12 of the hinge hinge and the hinge 6b of the connecting member 5.

In this position, the articulation 6a is raised in the up position along the panel A.

The surfaces 8a, 8b remain contiguous with each other, while the surfaces 8c, 8d form between them an articulation angle.

To simultaneously obtain the coincidences described with reference to figures 2 and 3 , it is advantageously provided that the spacing of the joints 6a, 6b corresponds to the stroke of the blade 2 actuating between these extreme positions of locking and unlocking.

On the figure 4 , the articulated opening with its panels A, B is shown in an intermediate position between the locking and unlocking.

In this intermediate position, the axis 12 of hinge coincides neither with the axis 6a, nor with the axis 6b of the connecting member 5.

The surfaces 8a, 8b form between them a first hinge angle, while the surfaces 8c, 8d form between them a second hinge angle. The sum of the aforementioned first and second articulation angles is equal to the total relative articulation angle of the panels A and B.

Due to the fact that the connecting member 5 is doubly articulated, this double freedom of movement allows the complete release of the member 5 and causes no parasitic force on the joints 6a and 6b.

Thus, thanks to the invention, the locking and unlocking of an opening become possible even in the hinge position; in addition, no parasitic force is transmitted to the mechanism of the device during this locking or unlocking as described in FIG. figure 4 .

The invention described with reference to a particular embodiment is in no way limited thereto, but on the contrary covers any modification of shape and any variant embodiment of the invention, the essential point being that a link with a double articulation simultaneously allows the articulation of the sections of the opening as well as its locking and unlocking.

The three successive elements: portions 4a, 4b and 5 are thus articulated by means of the invention to follow the movement of the panels A, B, during the opening and closing of an opening or a sectional door .

The articulation of the three successive elements: portions 4a, 4b and member 5, and the opening and closing of an opening or a sectional door are made in locked position and unlocked, thanks to the invention.

The articulation of the three successive elements: portions 4a, 4b and member 5 allows the transmission of an axial force and allows the rotation of the panels A, B about their hinge axis 12.

When the opening or sectional door is closed, the three successive elements: portions 4a, 4b and 5 member are aligned. The three successive elements: portions 4a, 4b and 5 member cooperate then allowing the transmission of an axial force, which allows their movement and performs the locking or unlocking of the device according to the invention.

When opening the opening or sectional door, the panels A, B pivot about their geometric axis 12. The three successive elements: portions 4a, 4b and 5 pivot member about the axis 6a when the opening or sectional door is locked, or around the axis 6b when the opening or sectional door is unlocked, thanks to the invention.

In both cases, the pivoting and lifting of a sectional garage door, a flap gate opening wide is possible.

In the case of an intermediate position, the axis of rotation of the panels A, B is between the axes 6a and 6b. The articulation of the three successive elements: portions 4a, 4b and member 5 is also possible thanks to the invention, with partial rotations combined around the axes 6a and 6b.
