Abstract

The invention relates to a closure assembly for a double door comprising an opening leaf (1) and a fixed leaf (2), said assembly comprising electromagnetic locking closure means and mechanical locking means. The electromagnetic locking closure means lock the opening leaf in the closed position on the fixed leaf, by means of magnetic attraction between magnetic door strikes (12) and cooperating counter plates (22). The mechanical locking means can be used beforehand to lock the opening leaf in the fixed position on the door frame (3) under the control of a cremone bolt mechanism (5) that does not include side bolts. The magnetic door strikes and the counter plates are housed, respectively, in a strip profile (11) mounted on the fixed leaf and in a handle profile (21) mounted on the opening leaf.

Description

The present invention relates to locksmith equipment with electromagnetic locking which are manufactured in metal joinery to be mounted on door leaves in situations where it is sought to obtain a high degree of operational safety in opening and closing doors while respecting the requirements of industrial exploitation in favorable economic conditions.

Locksmith assemblies used in such conditions are known in which electromagnetic locking means between the frame and the shutter in the closed position comprise a first profile of the electromagnetic suction cup receiving section and a second section of receiving post of counter plates capable of cooperating with each other. with suckers by attraction or magnetic repulsion. The two profiles are configured to constitute amounts vis-à-vis one on the door leaf and the other on the frame.

The assembly is completed by a control circuit and electrical power cupping. When in the closed position, the movable or opening leaf, is closed on the fixed leaf or dormant, the activation of the electromagnetic locking means couples each against-plate with the corresponding suction cup, these two cooperating elements being opposite one of the other.

In the most common case, the first section, the one which accommodates the suction cups, is configured to form a strip section to form amount on the frame, namely generally the fixed frame of the frame flanking the door leaf, then that the second profile is configured as a handle profile to form amount on the leaf. The reverse is however achievable without difficulty, and there are even upright profile configurations that are designed to accommodate either the suction cups or the backplates.

The invention aims to take advantage of the advantages of electromagnetic locks, particularly in terms of safety of the

INCORPORATED (E) BY REFERENCE (RULE 20.6) locking and convenience of operation, while lending itself to double doors, one being a semi-fixed leaf.

Thanks to the invention, it is possible to use electromagnetic locking locks to constitute first locking means between the two leaves by avoiding the fact that in conventional applications, the lock security requires that one of the two leaves be a dormant remaining fixed, always in the same position, that the opening leaf is open or closed against him.

For this purpose, the invention proposes to combine such first locking means, electromagnetic type, with second locking means, which are them of mechanical type. The mechanical locking means are specific to the semi-fixed leaf. They are in fact means of condemnation of the semi-fixed leaf, which one implements before closing on him the opening leaf. They comprise a traditional type espagnolette, for example a key operated espagnolette operating a cylinder lock mechanism which actuates two rods unfolding in opposition along the jamb section, respectively to each of its ends. Each rod ends with a bolt capable of engaging in a fixed prevention fixed by a striker mounted through the frame framing the door.

The invention will now be more fully described in the context of a particular embodiment chosen by way of example as illustrated by the figures of the accompanying drawings, in which:

FIG. 1 shows a door with two leaves equipped with the closure assembly according to the invention, the opening leaf being shown during opening to reveal the fixed headband on the semi-fixed leaf in closed position;

FIG. 2 is a perspective view of the strip showing in particular the cylinder lock of the cremone valve;

INCORPORATED (E) BY REFERENCE (RULE 20.6) - Figure 3 is an exploded perspective view and partial section of the two section profiles in their relative arrangement;

- Figure 4 is a cross-sectional view of the two assembled sections;

FIGS. 5 and 6 are cross-sectional views of a strip profile equipped with a raising profile used for catching up when, in particular, in renovation work, it is necessary to face an unevenness on an existing leaf.

FIG. 1 illustrates a double-leaf door according to the invention in a general view that makes it possible to distinguish an opening leaf 1 and a leaf 2 represented in the closed position in the plane of the frame structure (frame 3), whereas in reality it is a semi-fixed leaf on which the opening leaf 1 is locked in the closed position.

Here, as elsewhere throughout the present text, the term leaf or the term "battant" is used indiscriminately to designate the two movable elements in opening / closing of the door. They are mounted swinging on both sides of a fixed frame 3 framing the door as a whole.

Figure 1 assumes that the door is of the wing type opening by pulling on the right but it is clear that the same provisions could be used in a symmetrical embodiment where the door would be of the opening type by pulling to the left.

According to the invention, the closing assembly of the door comprises two locking devices, one of them constituting electromagnetic locking means whose function is to lock the opening leaf 1 on the semi-fixed leaf 2, the other component mechanical locking means which serve to condemn the semi-fixed leaf in its closed position by a cremone system.

In the particular case illustrated, the espagnolette system is of the cylinder and control key type. Thus, in FIGS. 1 and 2, the housing of the locking mechanism appears

INCORPORATED (E) BY REFERENCE (RULE 20.6) 5 with its cylinder 6 by which is introduced the control key of the lock. This lock controls a transmission mechanism by linkage to the two end bolts. Only the bolt 7 at the upper end of the leaf has been shown in Fig 1, to show that when it is deployed to condemn the leaf, it enters a keeper 8 which is part of the frame frame framing the door as a whole (frame 3), being reported on the upper rail of the latter.

The electromagnetic locking assembly that makes it possible to close the leaf opening on the leaf that has become stationary is itself conventional in that it comprises a strip element 1 1 that is mounted on the amount of the semi-fixed leaf 2, which becomes equivalent to a dormant leaf when locked in a fixed position.

In this strip are housed the electromagnetic suction cups 12. In cooperation with the suction cup, the electromagnetic locking system comprises a post profile configured to support plates against ferromagnetic material. Here it is a handle element 21 which in the particular case is shown with the same profile all along its height as an upright on the outside of the opening leaf 1.

This handle is shaped internally to receive the counter-plates 22 (Figure 4) in provisions coming opposite each electromagnetic pad 12 of the strip.

In FIG. 2 as in FIG. 1, the strip is represented without the lid 13 (which appears in FIG. 4) which slidably fits on the strip profile itself in several sections covering the zones of the strip between the stripes. electromagnetic cupping without hiding these.

It is clearly seen in Figure 2 the linkage system running along the band by two tring 14 and 15, unfolding in opposition, one upwards and the other down. The internal rod return mechanism specific to the lock 5 has not been shown.

INCORPORATED (E) BY REFERENCE (RULE 20.6) Figures 3 and 4 show in more detail the profile of the two elements or profiles of cooperating amounts, sucker support band and support handle against plates, in their relative position cooperating by the coming of the against-plates opposite suckers.

It contains most of the classical elements of electromagnetic locking assemblies as they may have been described in different publications. From this point of view, reference will be made here in particular to the whole of the description contained in the French patent published under the number FR 2 865 230.

The specificities of the profiles related to the present invention mainly concern the strip, and more particularly the profile of its bottom 16. It shows a central chute 17 of sufficient width to allow passage to the rod of the mechanical locking system, here rod 14. It is framed by two lateral chutes 18 in which the electrical cables of the electromagnetic locking system are housed by transmitting the power supply to the suction cups.

Figure 3 still shows a slot 19 formed longitudinally through the rod. This light is positioned in correspondence with a homologous light formed through the bottom 16 to guide the movement of the rod during the locking or unlocking operations controlled from the mechanical lock 5.

Finally, FIG. 3 shows the end bolt 7 fastened at the end of the rod 1 5.

With regard to the mechanical lock 5, it should be noted that the invention does not exclude that the cylinder and key control mechanism as illustrated is replaced by a simple removable crutch for the follower.

FIGS. 5 and 6 show diagrammatically in section an accessory element of the metal joinery assembly according to the invention, which consists of a headband riser making it possible to make up the false angles between the profile of

INCORPORATED (E) BY REFERENCE (RULE 20.6) headband and the amount of flap specific to an existing door receiving this profile.

This extension has the same profile as the amount profile that it completes for part of it, with a bottom 31 and two side faces 32 and 33. Although this is not clearly the case on the figures it may be advantageous to provide that these side faces come to reign with those of the strip section itself when the raiser is fully depressed on the strip for a recovery of minimum plumb.

The riser profile has the same lights as the strip profile for the passage of fastening screws in the flap receiving the stud profile, so here the semi-fixed flap. The gap between its bottom and that of the amount profile itself, ie the spacing between the two funds, is adjustable depending on the plumb thickness that is to catch up. For this purpose there are provided bolts 35 which are screwed into the thickness of the bottom of the profile to bear at their end on the bottom 31 of the riser.

It will be noted that extensions with a similar function are also provided for the frame of frame to adjust the place of strikes in which must enter the end bolts of the strip when closing the locking system of the fixed leaf.
