Description

Shabbat headband

The present invention relates to locksmithing equipment with electromagnetic locking which is manufactured in metal joinery to be mounted on door leaves 5 in situations where it is sought to obtain high operational safety in opening and closing doors while respecting the requirements of industrial exploitation under favorable economic conditions.

Locksmithing assemblies are used which are used in such conditions in which electromagnetic locking means between the frame and the leaf in the closed position comprise a first profile for the receiving amount of electromagnetic suction cups and a second profile for the receiving amount of counter plates suitable for cooperating. with suction cups by attraction 15 or magnetic repulsion. The two profiles are configured to form uprights opposite one on the door leaf the other on the frame.

The assembly is completed by a control and electrical supply circuit for the suction cups. When, in the closed position, the movable (or opening) leaf closes on the fixed (or dormant) frame, the activation of the electromagnetic locking means couples each counterplate with the corresponding suction cup, these two elements cooperants facing each other.

In the most common case, the first profile is configured to constitute a strip profile, more simply called strip in the art, which is configured to be fixed by mounting on the frame, namely generally the fixed frame of the frame the opening, while the second profile is configured to be fixed by mounting on the opening, or wing. The reverse is however easily achievable, and there are even upright profile configurations which are designed to receive either the suction cups or the counter plates. Whoever mounts on the opening

09/19/17 is treated here as a handle profile, on the grounds that it carries a handle allowing to act manually on the sash.

The invention aims to take advantage of the advantages of electromagnetic locks, in particular in terms of locking security and operating convenience, while providing a method of opening and closing the door that can be used in emergency, for example in malfunction of the electrical circuits necessary for controlling the electromagnetic means in normal operating conditions. In this, the door closing assembly according to the invention will find great interest also in the equipment of premises commonly used by people of the Jewish religion.

To do this, the invention proposes to combine first locking means, of the electromagnetic type, with second locking means, which are themselves of the mechanical type and suitable for being used in rescue when as a result of voluntary or involuntary inactivation. electromagnetic means the door remained blocked in the closed position. As such, the elements of the door closing assembly according to the invention comprise a movable trigger device capable of acting as a guillotine in front of a strike guard receiving a mechanical lock bolt so as to close it by forcing the bolt to retract by releasing the lock.

In one embodiment of the invention, the assembly combines with an electromagnetic locking system between strip and handle profile a mechanical lock which controls a bolt for mechanical locking of the strip on the handle profile by displacement of a movable trigger between a position releasing the ejection of the bolt in a cooperating keeper of the strip profile and an open position of the door forcing the withdrawal of said bolt out of said keeper.

The invention will now be described more fully in its essential characteristics and advantages by referring to a particular embodiment of a door closing assembly.

The aim is to make the most of the potential of electromagnetic locking systems while people who keep the Sabbath, respecting the Shabbat requirements of the Jewish religion, should not have to touch any electrical control device.

But the same needs could arise in many other applications to which the invention would be equally suited. In practice, the invention provides the convenience of an effective mechanical device in short circuit of the electromagnetic locking system. For example, the interest would be to allow the opening of an electromagnetic lock door when accidentally the electrical control of this system is broken. In shabbat applications it is rather 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 the figures comprises the conventional elements of electromagnetic locking systems as they may have been described in various 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.

This is how there is a strip profile 1 which is configured to be fixed on one of the two leaves of the door, opening or dormant, namely in general the fixed frame which frames the door, which was not represented. In this strip take place the electromagnetic suction cups 12 (fig. 5), together with the elements of their electrical supply. The cooperating profile, which is fixed by mounting on the other leaf (opening 3 in FIG. 2) is illustrated in the form of a handle profile 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 plywoods are placed opposite the electromagnetic suction cups when the leaf is applied to the frame

ΊΉΙΒΟΝ

09/19/17 in the arrangement where the two sections are assembled, as illustrated in figure 5.

The handle itself is assembled by sliding along the base profile, only visible in Figures 1 5 and 2. It is however visible at 14 in Figure 5. Depending on the particular embodiments, it is arranged along the profile handle or only on part of it at breast height for manual entry.

The mechanical locking device specific to ίο the invention is illustrated broken down into 4 in Figure 1. On this one we see the housing 6 of the mechanical lock. It is housed in the receiver headband of the suction cups in a free space between them. A cover which has not been shown closes the strip in place, leaving free access to the suction cups 12 for the 15 cooperating counter-plates and to the cylinder of the lock for its operation by a key.

From the mechanical lock, FIGS. 1 and 2 show on the one hand the cylinder, here a European cylinder 7, the follower of which is accessible through a window 8 formed through the handle profile, and on the other hand the bolt 9 which is in particular a U-bolt, or cane beak, which retracts against a spring not shown to release the opening of the door.

In particular embodiments of the assembly according to the invention, it is advantageously provided, as a replacement or in addition, to make the cylinder accessible from the opposite side of the door, therefore through the fan on which the strip is fixed. . Furthermore, it can advantageously be provided that the mechanical lock can also be opened from the interior of the habitat by means of a pull tab of the bolt, for which suitable clearances appear in FIG. 1 through the side face of the strip opposite the exit of the bolt and through the homologous side face 11 of the handle section.

The device 4 for controlling the locking and unlocking of the mechanical lock causes the cylinder 7 to cooperate with a plate which will be designated here by the term trigger,

TH1B0N

09/19/17 reason that in one of its positions it allows the ejection of the bolt 9 out of the strip.

To this end, this trigger 22 has a rack tooth 23 (fig. 1) with which the pinion 17 of the wheel bit meshes. The trigger is constituted by a plate mounted movably on a retaining plate which is itself fixed on the internal side of the lateral 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 facing walls falling respectively under the strip and the handle profile in their assembled position.

In the locked position of the mechanical lock, the trigger is located in an extreme position to the right in FIGS. 1 and 2, to the left in FIGS. 3 and 4. The keeper of the strike 25 is then released and the bolt therein. freely penetrates into the gap between the two parallel walls of the side face 16 of the handle profile. When the lock is operated to open the door, the same trigger is driven to the left in the orientation seen in Figures 1 and 2, to the right as seen in Figures 3 and 4. It is then d '' close the prevention and thus force the bolt to retract in the strip.

In its part on the left of Figure 2 it is hollowed out according to a profile 25 in two levels of off-hook which moves in operation in front of a clearance opening 26 formed for the bolt 9 through the keeper that constitutes the internal wall of the lateral face 16 of the handle profile, between this opening and a homologous aperture opening which is located opposite through the lateral face 11 of the strip profile.

The trigger plate is thus movable between a folded position where it is erased by releasing the bolt towards its extended position locking the closed door and an advanced position where it closes the prevention location and requires the withdrawal of the bolt by acting on that -this by its profile off the hook. The door can then be opened by pulling on the handle or by pushing on the leaf carrying the strip.

It will be noted that although the invention is particularly suitable and therefore described here for combining 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 electric, namely in particular an electro-piston lock, comprising electric means for controlling the withdrawal of the bolt.

In FIGS. 6 and 7, an accessory element of the door closing assembly according to the invention is shown diagrammatically in section, which consists of a strip extension making it possible to catch the false balance between the strip profile and the clean frame to an existing door receiving this profile.

This enhancer 30 has the same profile as the strip profile 1 which it completes, as regards part of it, with a bottom 31 and two side faces 32 and 33. Although this is not clearly the case in the figures it may be advantageous to provide that these lateral faces come to reign with those of the strip profile itself when the extension is fully pressed onto the strip for a minimum recovery of balance.

The extension profile has the same lights as the strip profile for the passage of fixing screws in the frame receiving the strip. The difference between its bottom and that of the strip profile itself, in other words the spacing between the two bottoms, is adjustable according to the thickness of balance that is to be caught. To this end, bolts 35 are provided which are screwed into the thickness of the bottom of the profile until they bear at their end on the bottom 31 of the riser. FIG. 6 corresponds to a minimum leveling up and FIG. 7 to a relative position useful in the event of a significant false balance.
