  The invention relates to a half-open and safety device for a door, window or the like, fitted.

sliding on a sleeping frame.

  The present invention relates to the field of building hardware and relates, more particularly, to fittings of

  locking for sliding doors.

  There are already multiple locking fittings for sliding doors. In particular, in a very simplified configuration, it is installed in the front upright of the sliding sash, a pre-w housing capable of accommodating a control mechanism, in particular in the form of a slide, which can be maneuvered at least through an opening on the internal side of this amount. In fact, this slider comes to drive in translation a hook bolt having a protrusion in the rebate of said front upright so as to be able to cooperate, in the locked position, with a keeper installed in rebate on the upright

corresponding to the sleeping frame.

  In order to multiply the locking points of such a sliding leaf, it is also known to equip the latter with a lever or lever-lock. In particular, again, through a well-defined control mechanism man_uvrable using a handle or even a key element, it is brought into the locking or unlocking position at least one rod of man_uvre extending, where appropriate at the rear of a headrest, into the rebate of the front upright of this sliding leaf. This rod man_uvre acts on one or more locking members also able (s) to cooperate, once the sliding door closed on its frame, with strikes arranged in correspondence

at the level of the latter.

  In this locking position, it is also known to make the free end of the maneuver rod (s) cooperate, moreover capable of being projecting relative to the upper and / or lower cross member of the sliding leaf, with a keeper installed at the height of the upper cross member and / or

bottom of the frame.

  In the end, these fittings usually fitted to a sliding leaf are hardly able to maintain the latter in a partially open position. Furthermore and whatever the embodiment, when, before closing the opening, the locking fitting has been brought into its locked position, the locking members cannot be prevented from striking the corresponding strikes provided at the level of the sleeping frame, which in the long run can lead to damage which could hinder the

  proper functioning of said fitting.

  To remedy this drawback, it is quite common to equip the latter with an anti-false maneuver device, the principle of which is to prevent the locking control of the

  fitting until the door has been closed on the frame.

  Specifically, a child inside a dwelling while the adults are outside can inadvertently close the sliding door and actuate the locking fitting and, therefore, lock itself in the house without it

  can be reached by people who have stayed outside.

  It is within the framework of an inventive step that a solution was found to, not only, ensuring the maintenance, in a ajar position, a sliding leaf, but, moreover,

  incidentally, respond to the risk that has just been exposed.

  To this end, the invention relates to a half-open and safety device for a door, window or the like opening, slidingly mounted on a sleeping frame, characterized in that it is defined by at least one keeper implanted in rebate of the lower and / or upper crossmember of said sleeping frame, this keeper comprising at least one opening for receiving, in we to keep the opening ajar, of a pre-adapted locking member, brought into the locking position by a mechanism control of an appropriate locking fitting, to be protruding from the lower or, if appropriate, upper cross member of the opening. According to a preterential embodiment of the invention, said keeper comprises, in dahors of an opening for the reception of a blocking member in w e to keep the opening ajar, at

3 2826684

  at least one second pre-opening capable of accommodating this same blocking member, brought into the locking position, once the opening

  sliding closed on its sleeping frame.

  Advantageously, said strike is prewe able to define a stop capable of cooperating with said blocking member, brought into the locking position, so as to prevent said opening

  sliding to close on its sleeping frame.

  Preferably, said blocking member is defined by the free end of a pre-adapted maneuver rod, brought into the unlocking position under the action of the control mechanism corresponding to a bolt or bolt-lock, to be presented, projecting by relative to the lower cross member or, as the case may be,

  of the sliding sash.

  Other objects and advantages of the present invention

  will appear during the description which follows relating to

  to an embodiment given by way of indicative and nonlimiting example.

  Understanding this description will be facilitated by

  Referring to the appended drawing in which: 20. FIG. 1 is a diagrammatic representation of a sliding window opening kept ajar through a closing and safety device according to the invention; Figure 2 is a schematic representation in partial section of detail A of Figure 1, the opening being brought into the closed position on its frame; Figure 3 is a we similar to Figure 2, the sliding leaf being held ajar through the striker defining the interlocking device and safety conform

to the invention.

  As shown in the figures of the attached drawing, the present invention relates to a covering and safety device 1, more particularly intended for a sliding leaf 2

door, window or the like 3.

  Generally, such a sliding opening 2 is provided at its front upright 4 with a locking fitting 5 which, through a control mechanism 6, makes it possible to actuate one or

4 2826684

  several locking members, for example a hook bolt 7 capable of cooperating, in the locked position, with strikes 8 arranged in correspondence at the level of the fixed frame 9 on which

  is slidably mounted this opening 2.

  In this regard and according to the invention, the interlocking and safety device 1 is defined by at least one keeper comprising at least one opening 11 for the reception, in we of keeping the opening leaf 2, a member of blocking 12 prew apt, brought into the locking position by the control mechanism 6 corresponding to the fitting 5, to be projecting relative to the upper cross member 12 or, as the case may be, lower 13 of

sliding sash 2.

  Preferably, this keeper 10 also has at least one second opening 14 in which is able to engage the locking member 12 when, once the sliding leaf 2 is closed on the frame 9, this locking member 12 is brought into the locked position, again through the

control mechanism 6.

  According to another feature of the invention, this keeper 10 corresponding to the interlocking and safety device 1 is also designed capable of defining a stop 15 with which is able to cooperate even said locking member 12, when, before closing the 'sliding opening 2 on the frame 9, it was brought into the locking position under the action of the mechanism

control 6 of fitting 5.

  According to a preferred embodiment, said locking fitting 5 consists of a cremone bolt or locking bolt located at the level of the front upright 4 of the sliding leaf 2, the control mechanism 6 of this cremone bolt or locking bolt 5 being prew apt to actuate at least one operating rod 16 extending along this front upright 4 and having a free end 17

  likely to define the blocking member 12.

  More particularly, this free end 17 of the maneuvering rod 16 is pre-adapted, in the locked position, to be projecting, as the case may be, at the upper or lower end of said front upright 4, ie at the level of the cross-member

2826684

  upper 12, respectively, lower 13 of the sliding leaf 2. Thus, depending on the position of the latter, this free end 17 of the operating rod 16 is able to come to engage in one of the openings 11 , 14 of the keeper 10 or to cooperate with the latter, forming a stop 15, to prevent this opening 2 from being inadvertently closed on said frame

sleeping 9.

  Obviously, said striker 10 is located at the level of the fixed frame 9, more particularly on the upper cross member 18 or, lO as the case may be, lower 19 of the latter, so as to cooperate with this blocking member 12. As is more particularly visible in Figures 2 and 3, this keeper 10 can, in fact, be pourwe of several openings 11, llA, llB, llC in which can engage this locking member 12 for

  keep the sliding sash 2 ajar.

  In order to facilitate the identification and engagement of the blocking member 12 in any one of these openings 11, 11A, 11B, 11C, these are, in the sliding direction of the opening 2, of width 20 greater than section 21, we in this same direction, of this blocking member 12. Furthermore, in this same direction of movement of the opening 2, these openings 11, llA, llB, llC are delimited by edges vivid 22, so that under the action of the control mechanism 6 of the locking fitting 5, the free end 17 of the operating rod 16, defining this locking member 12, necessarily and without trial and error engage in any one of these openings 11,

llA, llB, llC.

  Finally, the latter give access to housings 23, 23A, 23B, 23C of frustoconical shape the bottom 24 of which is substantially

  adjusted to section 21 of the locking member 12.

  Thus, if through the large width of the openings 11, llA, llB, llC, engagement in any of the latter of the locking member 12 is carried out with ease, once it is brought into its fully locked position, it is able, in cooperation with the keeper 10, to keep it ajar

6 2826684

  sliding sash 2 with less play than the frame

sleeping 9.

  Finally and as appears from the above description,

  the present invention responds advantageously to the problems of the state of the art in the field under consideration. Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that there can be made various modifications to the forms, materials and combinations of these. various elements, without

  for that to move away from the framework and the spirit of the invention.
