FR2628783A1 - AUTOMATIC LOCK FOR LOCKING SLIDING ROD WITH MULTIPENES LOCK - Google Patents

Abstract

Lock for locking an existing lock rod 3 2. By moving a finger fixed to the rod, a sliding bolt is compressed and escapes under the action of a spring. The opening is carried out by the emission of one or more codes coming from the keyboard 12 controlling an electromagnet 4, which allows the release and the displacement of the rod 3.

Description

i 2628783 The present invention relates to safety locks provided

  to be added to ordinary multi-door locks

  points with high and / or low rods, in order to ensure the automatic blocking of at least one of these rods in the closed position by the single operation of the key in said lock. Locks of this kind are known in which the blocking of

  the rod is obtained by a manually operated sliding lock

  Slightly penetrating into a light made in the rod.

  Such blocking can also be ensured by the end of a lever biased by an eccentric element driven by a motor.

  described in French Patent No 2,535,775 of November 10, 1982.

  The present invention relates to a security lock which can be associated with any multi-point lock without intervention of an electric motor in order to obtain the blocking.

automatic lock.

  As will be seen below, it results from the availability

  sition recommended by the invention a simplification of the rod locking device, by means of numerous re-connected elements,

  not visible on the outside of the door, and whose function

  This is safe, flexible and reliable.

  According to the invention, the automatic lock for locking and

  additional security of a conventional lock ensuring movement

  ment and the maintenance of a high and / or low rod in the closed position is characterized in that it comprises, in combination for the mechanical part: - a finger carried by the usual rod, - a bolt, preferably beveled, constantly stressed in the locking position by spring, said locking position resulting from the simple movement of

  vertical translation of said rod and its finger due to the engagement of said bevelled bolt both above and below said finger, the opening being controlled both by an electromagnet energized for this purpose only manually by a lever or trigger

in solidarity with the said bolt.

  b) for the electrical control of the electromagnet, a shielded keyboard so as to resist vandalism, positioned on the door or on the frame thereof, comprising from 12 to 15 keys acting in codes on a micro- processor managing the determination of several codes composed of 4 to

  8 self-modifying signs at will.

  The appended drawing schematically represents an embodiment of the invention in which: FIG. 1 is an overall view of a door with a panel on which are mounted, on the one hand an ordinary key lock and rods low and high sliding vertically in strikes hollowed out opposite made respectively in the frame and in the ground, on the other hand a rod locking lock placed at will either to condemn the low rod as shown in strong lines, or to order the high rod as shown

dotted.

  FIG. 2 represents in enlarged view a detail of FIG. 1,

  and FIG. 3 is a view, also enlarged, of the mechanism of ver-

rusting in figure 1.

  In these figures, the same references designate the same elements.

  In FIG. 1, the reference 1 designates the door. The reference 2.1a key lock. The references 3 and 3 ′ respectively designate the

  low and high rods. Reference 4 designates the electro-

  mechanical blocking. In the example given, it acts

on the lower rod 3.

  In Figure 2 is partially shown the bottom rod 3 on which is fixed a cylindrical finger 5 for locking

  in the closed position thereof.

  Figure 3 shows in detail the locking device of the lock 4!

3 2628783

  of the rod 3. does lock includes a bolt 6, beveled in this

  example, which is constantly in the closed position

  ture by a spring 7 and an electromagnet 8 included in a case 9. The electromagnet 8 is connected to the shielded keyboard 12 or 11 directly by a conductor & two wires or by a double spring contact placed in frame rebate . Permanent keyboard power

  12 is provided by a 12-volt battery provided with a trans-

trainer-rectifier 10.

  The operation of the locking device is conditioned by

  the closing movement of the lock.

  It is carried out by the displacement A of 2a rod 3 and of finger 5, which allows the bolt 6 to escape according to ia-value B, under the action of the spring 7 initially compressed, depending on the position of the bolt 6 by the dashed line and overcompression C caused

  by moving the finger 5 on the inclined plane of the bolt 6.

  e bolt 6 in-this new position opposes any translation

finger 5 and rod 3.

  To obtain the opening of lock 2 from the outside, simply insert the key in it, dial on the keyboard one of the preset codes, comprising from 4 to 8 signs, plus a validation key provided - for the electrical supply of the electromagnet 8 for controlling the bolt 6 positioning the latter according to the dotted line and according to the displacement E, which allows the release of the finger 5 and of the rod 3 for the displacement D carried out by the opening rotation of the key in the lock 2, the interruption of the electrical supply to the electromagnet 8 releases the spring 7 which brings the bolt 6 into contact with the finger 5

following the dashed line.

  To obtain the opening of the lock 4 from the inside, it suffices to manually move the lever or trigger 14 integral with the bolt according to the value E, which allows the release of the finger 5 and of the rod 3 for the vertical displacement effected with the key. of lock 2, the release of this trigger brings the bolt 6

  in contact with finger 5 along the dashed line.

  Note that this opening can also be done from

  ! 1interior by an electrical contact supplying the electro-

  magnet S. a dea codes can be assigned to the opening "under duress" and will supply two relays: one for the opening of the lock, the other for a visual and / or phonic remote alarm and / or a

telephone transmitter.

  It is understood that any variant inspired by the design yes is the basis of the invention and would not go beyond the scope of this

last.
