Description

DEVICE FOR CLOSING A SLIDER

  PROVIDED WITH MEANS TO AVOID FALSE MANEUVER

  The present invention relates to closing devices that are more particularly found on doors or windows that slide on rails, for example the French windows of certain residential houses.

  technicians call sliders.

  To obtain the closure of a sliding device has been realized

  of a particular type These devices comprise a lock and a strike.

  The lock essentially comprises a body in the form of a recessed slide, a slide mounted in translation in the recess of the slideway, a hook mounted integral with the slide and emerging from the body by a slot made in the body, this hook constituting the bolt of the lock This lock is thus embedded in an amount of sliding, a groove being made in the amount so that users can access

  slide and maneuver it by sliding it into the lock body.

  The lock is arranged and installed in the amount of the sliding so that the bolt or hook can cooperate with the strike which, it is

mounted solidarity of the doorframe.

  To close a slide with such a lock, simply slide it until the bolt enters the lock and then

  maneuver the slide so that the hook comes to position itself behind

  re a projecting part of this waste.

  To open a slide simply slide the slider in the opposite direction to release the hook of the projecting portion of the striker, then

  slide the slide on its rails to get it open.

  Such a lock gives complete satisfaction in terms of the

  but may have the disadvantage of having a relatively long service life-

short.

  Indeed, it sometimes happens that, when a sliding is open, the hook

  which has been released from the protruding part of the strike for opening,

  not in the position it occupies in the strike for closing the slide

  and that it thus emerges from the sliding frame at the same level as the protruding part of the striker Si, for whatever reason, the sliding

  is pushed back strongly towards its closed position while the neck is

  sledge has not been maneuvered to clear the hook, the latter abuts violently against the striker This shock is almost every time, especially if the mass of the slider is relatively large, the destruction is the strike or the hook, or even of the whole

  slider closing device.

  To overcome this drawback, so-called "anti-false maneuvering" means have been developed, but these means have rather complicated structures which make the cost price of this type of closure relatively high. to develop a device for closing a slider, which comprises means avoiding false maneuvers such as that described above and which has a much simpler structure than that of devices of the same type of the prior art and

  therefore a lower cost price.

  More specifically, the subject of the present invention is a device for closing a sliding door on a doorframe, said device comprising

  a lock arranged on one of the two elements "sliding" and "chamber"

  and a keeper disposed on the other element, said keeper having an open housing delimited by a protruding portion bordering said housing and said lock comprising a body in the form of a recessed slide, a slider mounted in translation in the recess. said slide, a hook mounted integral with said slide and emerging from said body by a slot made in said body, said hook constituting the bolt of the lock adapted to cooperate with said projecting portion of said striker, the device being ca-25 characterized it further comprises: a rod cooperatively mounted in said body and adapted to take at least two positions, a rest position and a working position, elastic means for tending to maintain and return said rod in said position rest, and means for controlling the passage of said rod from its rest position to its working position against said elastic means when said The lock and said striker are in the vicinity of each other, and in that said slider comprises a stop adapted to come into contact with a first end of said rod when it is in its rest position and a notch located at side of said stop, said notch being adapted to receive said first end of said rod when it is in

  working position. Other features and advantages of the present invention will become apparent from the following description given with reference to the drawings

  Illustrative but not limiting, in which: The single figure shows an embodiment of a device for

  closure according to the invention comprising means for avoiding false

noeuvres.

  The closure device 1 illustrated in the single figure is more particularly

  intended to be associated, on the one hand, with a schematic

  2, that is to say for example a window or a door which slides on rails to obtain its opening or closing, and

on the other hand to a doorframe 3.

  This device comprises a lock 4 arranged, in the illustrated example, on the slider 2 and a striker 5 disposed on the other element, that is to say

the doorframe 3.

  The keeper 5 implanted in the frame 3 comprises a housing or-

  green 6, delimited and bordered by at least one projecting portion 7.

  The lock 4 comprises a body 8 in the form of a hollow slideway 10,

  constituted for example by a hollow cylindrical profile.

  A slider 11 is mounted in translation in the recess 10 of the slider.

  re 9 and a hook 12, mounted integral with the slider 11, emerges from the body 8 by a slot 13 made in this body This hook 12 constitutes the bolt of the lock which is adapted to cooperate with the striker 5, and more particularly

  with the protruding part 7 which borders the housing 6.

  The device further comprises, according to a feature of the invention

  The rod 20 is adapted to take at least two positions, a rest position 21 (shown in continuous lines in the figure) and a working position.

  22 (in broken lines on this same figure).

  The device comprises, associated with this rod 20, elastic means for tending to maintain it in its rest position, and to bring it there if,

  for whatever reason she had been left out.

  The device also comprises means 27 for controlling the passage

  of the rod 20 from its rest position 21 to its working position 22 at the

  against elastic means, when the lock 4 and the striker 5 arrive at

neighborhood of each other.

  The slider 1 i comprises a stop 24 adapted to come into contact with a first end 25 of the rod 20 when the latter is in its rest position 21, and a notch 26 or the like situated next to this abutment 24, this notch being adapted to receive the first end 25 of the rod

  when it is in working position 22.

  In an advantageous and preferred embodiment of the invention, the rod

  is rotatably mounted about an axis 28 in the recess 10 of the body 8.

  In the embodiment described above, the resilient means 2700578 for holding and retracting the rod 20 into its rest position 21 are advantageously constituted by the fact that the rod 20 is of a material having a certain value. This characteristic makes it possible to produce the rod and the elastic means in a single element. In this case, the second end 29 of the rod opposite to the first one 25 adapted to cooperate with the slide, is secured in the hollow 10 of the body. 8, by

  example, with a lug 30 This fastening can be done by the nest-

  in force around the lug 30 of the end 29 formed in a loop.

  This fixation is given for illustrative purposes only and other means of

can be used.

  In a preferred embodiment, the means 27 for controlling

  der the passage of the rod 20 from its rest position 21 to its working position.

  22 against the force exerted by the elastic means, are con-

  staked by a finger 31 integral with the rod 20 and able to come into contact di-

  directly or indirectly the striker 5 when the lock 4 and the latch 5 arrive in the vicinity of each other In the example shown, the free end 32 of the finger 31 abuts against the striker 5, at a location of this strike o, on the functional level, its shock is strictly equivalent to a

  impact against the doorframe 3, that is to say outside the entrance of the lodge.

6.

  The device described above operates in the following manner It is first assumed that the sliding is closed, that is to say that the hook 12 is in the position shown in phantom 40 The spout 41 of the hook is then placed behind and against the protruding portion 7 of the striker 5, preventing the slider from moving In this situation, the keeper 5 presses the end 32 of the finger 31 and the finger pushes the rod

  which thus occupies its working position 22, its first end 25 plunging into the notch 26.

  When a user wants to open the slider, he moves the slider

  11 to slide it downwards (with reference to the orientation of the figure) to make it take, as well as the hook 12, the position which is represented by

  When the slide is lowered, under the action of the elasticity of the rod, it returns to its rest position 21 and its first end 25 is placed just above the abutment 24.35. , while the sliding is open, a person inadvertently wants to go up the slider, the abutment 24 is opposed by his contact with the ex-

  In these conditions, if the slider is closed, that is to say if the lock 4 is brought back to the striker 5, the hook 12 is not facing the projecting part 7 does not abut against the striker at the risk of causing a deterioration of the device in its entirety.

2700578 seems.

  This device therefore has a security against false maneuvers such as that described in the preamble of this description.

  This security is achieved by the use of a very small number of elements additional to those constituting the prior art devices without safety. Moreover, these elements are completely integrated.

  in the lock and do not modify or complicate the installation of this lock They do not significantly increase the cost price of closing devices for sliding, but give these devices a life-time more important than the devices of the prior art.
