Description

ELECTROMAGNETIC LOCKING DOOR CLOSURE ASSEMBLY

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 under favorable economic conditions.

Locking assemblies used in such conditions are known in which electromagnetic locking means between the frame and the casement in the closed position comprise a first profile of the electromagnetic suction cup receiving section and a second counter-plate receiving post section adapted to cooperate with cupping by magnetic attraction or repulsion. Both profiles are configured for each other on the frame.

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

In the most common case, the first section is configured to form a strip section, more simply called strip in the trade, which is configured to be mounted on the frame, namely generally the fixed frame of the framing frame the opening, while the second section is configured to be mounted by mounting on the opening, or flapping. 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. Whoever gets on the opening is treated here as being a handle profile, on the grounds that it carries a handle allowing to act manually on the opening.

The prior art in the field has sometimes provided, as described for example in the patent document US 5865483, published February 2, 1999, to double the electromagnetic locking means of a retractable bolt lock whose bolt s' ejects in the prevention of a fixed strike when, when closing the door, suction cups and electromagnetic lock plates come close to each other.

The invention proposes to combine mechanical lock and electromagnetic lock in a completely different way. In principle, the mechanical lock being closed while the electromagnetic locking means have not been activated, it is not the bolt that is actuated, but a special lock that is movable to open a lock in which it was engaged. This special lock will be called trigger, to distinguish it from the lock associated with bolts in traditional locks.

The invention makes it possible to take advantage of the advantages of electromagnetic locks, in particular in terms of lock safety and convenience of operation, while at the same time providing a mode of opening and closing the door that can be used as a backup, for example in case of malfunction of the electrical circuits necessary for the control of the electromagnetic means in normal operating mode. In this, the door closure assembly according to the invention will find great interest also in the equipment of premises commonly used by people of Jewish religion. In this case, the Sabbath days, the electromagnetic type locking means will have been deliberately inactivated and the mechanical lock has been ordered, most frequently from the inside, to bring it into the configuration where the bolt is engaged in the prevention that forms the trigger in front of the striker side of the headband. Then, the people who come back in the places have this mechanical lock, which there controls from the outside, without implying any use of the electricity, to actuate the trigger mobile in moving towards the position which opens passage to the bolt by retracting the movable restraint.

More specifically, in the preferred embodiments, the mechanical lock comprises firstly a control mechanism of the bolt, possibly a simple zipper acting against a spring, and secondly a mechanism trigger switch between a closed door position and a release position of the connection between bolt and lock where it is sufficient to grasp the handle to open the door, opening or pushing in each case.

The invention will now be further described in its features and essential advantages with reference to a particular embodiment of a door closure assembly according to the invention and with the aid of the accompanying figures and drawings in which:

FIG. 1 represents essential elements of the assembly in a partial view in exploded and in perspective distinguishing in particular the strip receiving the electromagnetic suction cups from the handle profile which completes with it the system with suction cups and counter plates constituting the locking means electromagnetic.

FIG. 2 is a more detailed view of the central portion of the assembly at the level of the mechanical means for locking and unlocking the door, made in the form of a cylinder and key lock complementing a retractable bolt mechanism latching in a lock prevention.

FIG. 3 schematizes a view taken towards the handle section from the inside of the strip to show the cooperation between the trigger and the pinion of a wheel bit as they cooperate to retract the movable restraint and thus release the bolt that include the mechanical means even if it is in the extended position.

FIG. 4 is a longitudinal view in partial section, homologous to FIG. 3. Figure 5 shows schematically the assembly according to the invention, comprising the strip and the handle section in their r mated position, in u view in section at an electromagnetic pad and the associated counterplate.

FIGS. 6 and 7 are views in section of a strip profile equipped with a raising profile used for catching up the plate when, especially in renovation work, it is necessary to face a false -aplom b on an existing frame.

In a particular embodiment, the figures show an electromagnetic latch door closure assembly equipped with a mechanical release lock with an unlocking trigger, in an example of application where it is more particularly designed to equip the premises intended to receive persons of Jewish reliance.

The aim is to make the most of the potential of electromagnetic lock locking systems, even though Sabbath keepers, in keeping with the Shabbat requirements of the Jewish religion, must not have to touch the least control device. electric.

But the same needs could arise in many other applications to which the invention would be equally suitable. In practice, the invention provides the convenience of an efficient mechanical device bypassing the electromagnetic locking system. For example, the interest would be to allow the opening of a door to electromagnetic lock when accidentally the electrical control of this system is down. In Shabbat applications it is more a question of allowing people to enter the room on Sabbath days, the electromagnetic locking system having been voluntarily deactivated.

The assembly according to the invention as shown in FIGS res comprises the conventional elements of electromagnetic locking systems as they may have been described in various pu blications. From this point of view we will do here reference in particular to the entire description contained in the French patent published under the number FR 2865230.

Thus, there is a strip profile 1 which is configured to attach to one of the two leaves of the door, usually a frame formed by the fixed frame which frames the door, which n ' was not represented. The particular case described assumes that it is in this band that the electromagnetic suction cups 12 (FIG 5) take place together with the elements of their power supply. The cooperating section, which is mounted on the other leaf (opening 3 in Figure 2) is illustrated in the form of a handle section 5. It is configured to receive the counter plates, made of ferromagnetic material. The two profiles are of course fixed on their respective supports in a position such that the counter plates are placed next to the electromagnetic suction cups when the opening is applied to the frame in the arrangement where the two sections are assembled, as it is illustrated in Figure 5.

The handle itself is assembled by sliding along the base profile, only visible in Figures 1 and 2. However, it is visible at 14 in Figure 5. According to the particular embodiments, it is arranged all along the profile of handle or only on a part of it at man's height for manual entry.

The mechanical lock device specific to the invention is illustrated broken down at 4 in FIG. 1. On it is seen the casing 6 of a cylinder lock. It is lodged in the receiving band of suction cups in a free space between them. A hood that has not been shown just closes the headband in place, leaving free access to the suction cups 12 for the cooperating counter-plates, leaving free access to the lock cylinder for its operation by a key.

Of this mechanical lock, FIGS. 1 and 2 schematize on the one hand the cylinder, here a European cylinder 7, whose key slot is accessible through a window 8 formed through the handle profile, and on the other hand the bolt 9 which is particularly a latch bolt, where bolt piston, with beveled face, which retracts to against a spring (not shown) to release the opening of the door. By means of this lock, we do not act on the bolt. It controls the movement of the trigger 22, along the face formed by the face 11 of the strip, between an armed position placing the prevention that it forms in correspondence with that of the associated bolt, and a position of unlocking by retraction of the empênage.

In a nonlimiting manner, in the case of a particular embodiment, the bolt of the system according to the invention is here assumed to be operable by a pull tab passing through the opposite face of the strip. For good security conditions against the risk of burglary, the mechanism of operation of the bolt must not be accessible from outside the space to be protected. On the other hand, as a variant of the latch bolt, it would be preferable to use a bi-directional bolt between the output position and the retracted position, or several bolts with simultaneous control, possibly from a mechanism with a cylinder other than that which controls the unlocking. by the trigger. Note also that the concept of mechanical lock is not meant to exclude so-called electromechanical locks, so for example the mechanisms with electropiston bolt.

Returning to Figure 1, the end of the cylinder that can be seen under the band belongs to the trigger control lock. Indeed, in particular embodiments of the assembly according to the invention, it is intended to make the cylinder accessible on the opposite side of the door, so through the leaf on which the band is fixed. Furthermore, since it is expected that the unlocking action on the bolt is carried out from within the habitat by means of a drawbar of the bolt, there appears to be a suitable clearance formed through the lateral face of the strip opposite the bolt outlet and through the homologous side face of the handle profile.

The device 4 for unlocking control of the mechanical lock cooperates the cylinder 7 with a movable plate that is designated here by the term trigger, double pattern that it provides a restraint and that the unlocking involves moving it away from an armed position to release the bolt from its grip.

For this purpose, this trigger 22 has a toothed rack 23 (FIG 1) with which meshes the pinion 17 of a wheel bit located at the outlet of the cylinder 7. The trigger is constituted by a movable plate mounted on a holding plate itself attached to the inner side of the side face 16 of the handle profile. The rotation of the pinion by means of the key driving the bit causes the trigger to move along the walls facing each other, which respectively fall on the strip and the handle profile in their assembled position.

In the closed armed position of the mechanical lock, the trigger is located in an extreme position where it provides a lock keeper 25 adapted to receive and trap the bolt 9 when the door is closed. When operating the lock to open the door, the same trigger is driven to the right in the orientation seen in Figures 1 and 2, to the left as seen in Figures 3 and 4. In its part on the left of Figure 2 it is hollowed in a profile 25 in two levels of off-hook which moves in operation in front of an opening of prevention 26 formed for the bolt 9 through the keeper that constitutes the inner wall of the side face 16 of the profile of handle, between this opening and a homologous locking opening which is opposite through the side face 11 of the strip section.

Note that although the invention is particularly suitable and therefore described here to combine a mechanical lock device with electromagnetic locking means, it would also be advantageous to use it in combination with other types of closure involving a current electrical, namely in particular an electro-piston lock, comprising electrical means for controlling the withdrawal of the bolt.

FIGS. 6 and 7 show schematically in cross-section an accessory element of the door closure assembly according to the invention which consists of an extension of the strip making it possible to make up the false level between the strip profile and the clean frame to an existing door receiving this profile. This riser 30 has the same profile as the profi le headband 1 it completes, for what u is part of it, with a bottom 31 and two side faces 32 and 33. Although this is not If it is not clearly the case on the figu res it may be advantageous to provide that these side faces come to reign with those of the band section itself when the raises is completely depressed on the headband for a b min imal aplom recovery. .

The extension profile has the same light as the strip profile for the passage of fixing screws in the frame receiving the strip. The gap between its bottom and that of the strip section itself, in other words the spacing between the two bottoms, is adjustable according to the plumb thickness that is to catch up. For this purpose bolts 35 are provided which are screwed into the thickness of the bottom of the profile until they are supported at their end on the bottom 31 of the riser. FIG. 6 corresponds to a minimum imitation trim and FIG. 7 shows a relative position that is useful in the event of a false air suspension.
