Abstract

The device has a stop system comprising a horizontal stop slide (3) actuated by springs and a lever connected to a grief stem controlling system. The stop system is adapted such that the impact of the closing of a door (18) takes place in an inner part (51) of a jamb (17) or on an outer part (52) equipped with a semi-rigid counter buffer (20). The slide (3) slides on a reinforcing plate (14) fixed on the door.

Description

- DESCRIPTION -

  The present invention relates to a device preventing the unexpected closure of a door to avoid inconvenience and personal injury.

  The well known problem of the doors is that of anyone who is stranded outside his apartment without keys because his door between open has just closed under the effect of a draft, with sometimes the risk of being pinched.

  This inconvenience always requires the costly intervention of a locksmith not to mention a bodily injury that can be serious such as fingers cut or crushed.

  The device according to the invention overcomes this disadvantage. It has indeed a retractable stop system which is activated as soon as the abandoned door is left open, that is to say that it can no longer close by itself will come to the end of the race bang on the door jamb or against a sufficiently thick abutment to leave a gap of at least the thickness of a finger. This security is sought especially for young children who handle the doors without attention.

  On the other hand, when the user wishes to close the door, he actuates a control system to deactivate the stop function, that is to say that the bolt and stop system slips away to allow the door to come to rest. on the doorframe.

  This new device according to the invention brings simplifications of realization compared to the patent n 0207605 of the same inventor and published on 26/12/2003 under the number 20 2841285.

  According to the accompanying drawings; FIG. 1 is a cross-sectional view of the device according to the invention; FIG. 2 represents, in front view, the internal mechanism of the device; FIG. 3 represents, in vertical section, a variant of the device; FIG. represents, in front view, the inside of the mechanism according to another version of the device The device shown in Figure 1 is mounted on a door (18) with its conventional locking system. To know; two handles, one external (22), the other internal (16), mounted on a square rod (7) connected to a lock (19) which controls a half bolt (2) to be housed in a striker (23) of jamb (17).

  The device which comprises a housing (10) is plated and screwed on the door (18) on the outside.

  The mechanism of the device according to Figure 2 shows the stop system comprising a horizontal stop slide (3) actuated by springs (9) (8) and a lever (4) connected to a square rod control system (7). ) equipped at its ends with handles (16) (22).

  The stop system may comprise an extension (15) made integral by simple conventional mechanical method such as screwing (13), riveting, gluing ... to allow adjustment on any door whose odds may vary, such as the distance of the door. axis of the handle (7) relative to the border (24) of the door.

  The stop system can be adapted so that the end-of-travel impact of the door closure takes place either in the inner part (Si) of the door frame (17) or on the outer part (52) equipped with a counter abutment (20) semi-rigid to allow, in this case, the shock mitigation and a sufficient clearance vis-à-vis the thickness of the fingers of the hand of the children that we want to protect. A detail is to be noted concerning the stop (3); it slides on a reinforcing plate (14) fixed to the door (18) to prevent any deformation of the device at the time of impact on the doorframe (17).

  Figure 3 shows in vertical section a variant of the device that applies more particularly to a landing door having no external handle. The stop (3) moves in the same way, ie horizontally in the housing (10), under the combined action of the springs (8) (9) and the levers (4) (4A) of which the one is actuated by an inner handle (16) connected to a square rod (7) and the other is actuated by a key (12) inserted into the barrel (6) located in the extension of the axis of the square rod . This barrel (6) can very well be installed beside and below the axis to control the displacement of the stop (3) by a lever (4A) along a larger radius.

  In this variant, Figure 3, the user who wants to leave his home must imperatively in his keychain key (12) to retract the stop (3) and close its door (18). This key (12) serves only for closing the door.

  However, the barrel assembly (6) and key (12) can be replaced by an outer handle (22) remaining permanently.

  With regard to the lever (4) actuated by the handle (16), the latter may be constructed of a rigid or spring-like material, like spring steel, to absorb the differences in travel distances of the half-bolt (2) and the stop ( 3).

  On the other hand the device is designed so that the housing (10) and its mechanism is reversible. That is, it can be mounted on a door pushing right or pushing left.

  According to another more compact version of the device, according to FIG. 4, the stop (3 ') is tilted about an axis (21) in a housing (10') under the combined action of the springs (8 ') (9 ') and levers (4') (4'A) themselves actuated by a square rod (7 ') and a cylinder in the case of a landing door.

  In this version, the stop (3 ') may contain an extension (15') having the same function as that previously described for the stop (3).

  The device according to the invention is particularly intended to equip any door with a habitat. It can be factory installed, or mounted in Kit version by any individual having the sense of DIY.
