- DESCRIPTION

  The present invention relates to a device preventing the unexpected closing of a door for

  avoid unpleasantness and personal accidents.

  The well-known problems of landing doors is that of anyone who finds themselves blocked outside their apartment without keys because their door opened slightly closed under the effect of a draft, with sometimes the risk we know of being pinched

the doipts.

  This annoyance always requires the costly intervention of a locksmith, not to mention an accident.

  which can be serious such as doipts cut or crushed.

  The device according to the invention makes it possible to remedy this drawback. It in fact comprises means of retractable stops which take up position or activate as soon as the abandoned door is left open, that is to say that the latter can no longer close by itself.

  race bang on bumpers thick enough to leave at least the thickness of a finger.

  This security being sought especially for children in teas age who handle the doors without attention. On the other hand, when the user wishes to close the door, he actuates simultaneously at the level of the handle control means to deactivate the stop hubs, that is to say that the

  latch system and stopper slips to let the door come to bear on the doorframe.

  Other advantages and characteristics of the invention will appear below in the description.

  detailed which will follow according to an embodiment of the device of the invention given by way of nonlimiting example and illustrated by means of the annexed drawings in which:

  - Figure 1 shows a perspective view of a first variant of the device with two buffers.

  - Figure 2 shows the exterior handle with its mechanism seen along arrow F of the

variant figure 1.

  - Figure 3 shows a sectional view of the mechanism of Figure 2.

  - Figure 4 shows a perspective view of a second variant of the device with a single

  bumper rises in excess thickness of the door.

  - Figure 5 shows a perspective view of a third variant of the device with a single stopper

  installs in the thickness of the door.

  Referring to FIG. 1, the device comprises means of retractable stops represented by the housing (2) mounted on the door (1) provided with a pin (3) bearing on a spring (4),

  and a stopper (5) mounted on the frame (12).

  In the door configuration left open, the active wind stop means, that is to say

  that the bolt (3) will strike the stopper (5) if the door moves in the closing direction.

  -2 In the case where one consciously wants to close the door of the interior it is necessary to use the means of

controls mounted on the door (1).

  They include an interior handle (6) actuating a lever (15) which controls the movement of a linkage (9) then another lever (10) whose function is to retract the bolt (3) while compressing the spring (4). In the case where you consciously want to close the door from the outside, you have to activate the external handle (7) linked to the cabinet (8) comprising lever (16) and spring (17) taking care to press before on the press button (11) represents in FIGS. 2 and 3. If one does not respect

  this instruction the handle remains locked by the tongue (20) which abuts on the push button (11).

  o The whole device can equip the entire height of a door with two buffers (5) high and teas or as in a second variant (Figure 4) the device can be reduced in size

  included in a volume (18) in excess thickness of the door (1) provided with a single bolt (3) and stopper (5).

  The latter, tail whatever the mounting variant, is equipped with an elastic shock plate (13)

  reducing the intensity of the impact and the noise it causes.

  Depending on the use sought the stopper (5) may contain a striker (14) for holding the door

enter open.

  - Figure 5 shows a third variant of the device which is mounted in the thickness of the door. It is composed of the same elements, such as handles (6) (7), linkage (9), lever (10), bolt (3),

  o buffer (5) installed in a boftier (21) including the traditional lock (19).

  According to a fourth variant, the mechanisms of each of the handles 6 and 7 could be

  combined so that the axes of the handles are aligned.

  According to another variant, the device contained in the thickness of the door can be miniaturized

  to enter a volume correspond to traditional locks (19) to facilitate the exchange.

  : 5 In this same volume the device can also be very simplified in case we want to use it for

  any door including the interior doors of an apartment.

  In this configuration the mechanism of the lock remains traditional with the difference that the bolt is constructed in a parallelepiped shape instead of being beveled (22) to facilitate contact on the corresponding stopper mounted on the frame. The device according to the invention is particularly intended to equip any apartment door mounted

  original factory or kit version that any handyman can assemble by himself.
