FR2838474A1 - Fastening mechanism for motorized gates comprises sliding part which is translated horizontally by motorization operating part to engage strike plate and through transmission rod penetrates bolt into shoe - Google Patents

Abstract

The locking mechanism for a motorized gate operates by locking one leaf (P1) relative to the other (P2). A sliding part (OC) fixed on one leaf engages a strike plate (G) on the other leaf during closing of the first leaf. This closing drives the horizontal translation of the sliding part caused by the pressure of the operating part (OM) of the motorization (M). A movement transmission device drives a rod (T) terminated by a bolt which penetrates into the ground shoe (GS).

DESCRIPTION

  The present invention relates to a device for securing the two leaves of an opening carved in particular of a portal driven by a motor whose movement transmission member immediately in contact with the leaf of the

  portal forms an acute angle with the internal face of said leaf.

  There are several devices which try to solve the problem of closure

  effective gate leaves, which can be divided into two categories.

  The first category includes electrically controlled organs such as electric locks, electromagnets, which have a significant additional cost and are difficult to install because the operating ranges of these products are often unsuitable

  to the modifications undergone by the gates according to the temperature differences.

  The second category includes mechanical locking devices such as

  ground strikes or the irreversibility of motorizations. These achievements are summary and

  very dependent on the structure of the portal. Indeed, a light and quite wide gate will have a flexibility often detrimental to its good closing, a weighing on a leaf which can dissociate it very easily from the other leaf, suggesting

  that the motorization is badly installed.

  It is nevertheless in this category that we know two realizations which offer interesting solutions. First of all, an American patent US 4 625 455 A of December 2, 1986 which describes a closing device which uses a principle of permanent sliding of a horizontal member which effectively fulfills the closing function, but does not authorize an adaptation simple at doors and gates. Indeed, it uses a double compass for the transmission of movement, a large footprint and it does not overcome a significant projection when the gate is

  open. In addition, its adaptation requires very precise adjustments.

  Another embodiment is described in French patent 2,811,701 of 2/17/2000. The proposed system also uses the principle of permanent sliding, a fork open on one side coming to be trapped in a stud fixed to the ground. This otherwise attractive solution is used in the context of the manufacture of a gate. It is exclusively usable for this application, and could not be implemented in a simple manner on existing doors or gates, due to the multiple constraints, the main one being the obligation to offset the axis of rotation of the gate being given the obligatory stroke of a link which allows the horizontal translational movement. This peculiarity prohibits any adaptation on doors or

existing portals.

  The object of the present invention is to remedy these drawbacks while proposing

  a simple and inexpensive solution.

  The device according to the invention is a locking device for a motorized door or gate with at least one leaf, of the type with a locking system in a keeper, in which the motorization means are connected to a sliding member OC longitudinally and horizontally with respect to to the leaf P1, provided with guide means on the portal, the free end C1 of the said sliding member OC ensuring the locking of the leaf P1 in the closed position by cooperation with a keeper G. such a device intended to be autonomous or adapted to the systems of standard motorization, either with articulated arms or electro-hydraulic or electromechanical cylinders with worm screw, bearing on an intermediate part of the leaf P1, characterized in that it also comprises a stop B arranged at the end C1 of the sliding member and opposite the keeper, comprising retraction means controlled by

  unlocking means actuated by contact with a fixed part constituted either by the opposite leaf in the closed leaf stop position, or by the opposite part of the frame in the case of a single leaf gate, or by a part of the strike or of an insert to ensure this function, so as to allow, after retraction of the stop, the movement of the sliding member OC and in particular the end C 1 of the sliding member in the keeper G opposite so not to allow the exit of the end of the sliding member only when the leaf arrives in the closed position without the sliding member being able to project from the gate being closed, allowing the leaf P1 to have an operation d 'appearance

  normal and avoid any prior stroke and positioning adjustment.

  Another characteristic of the invention, the retractable stop B is provided with a surface B1 directly forming a stop by contact with the free end C1 of the sliding member, the sliding of the member OC being released by pivoting. of the stop B. articulated in B2, obtained by contact of a part B4 with

  part of the strike cover fixed on the leaf V2.

  A remarkable characteristic of the invention, the retractable stopper B cooperates with a vertical slider VA with oblique light V1 and a pin of the sliding member C2 which moves in said light V1, both contained in a housing ^ le vertical displacement of the VA slider, resulting from the action of the pin C2 in the oblique opening V1, is clamped and prevented by the contact of a surface B1 of the retractable stop B with a projecting part V2 of the vertical slider VA during the

closing stroke of leaf P1.

  According to the foregoing, a characteristic of the invention is that the retractable stopper B is arranged perpendicular to the plane of the leaf P1,), its axis of articulation (B2) is parallel to the plane of the leaf (P1), substantially horizontal, and is arranged in its upper part on the side of the housing (S) opposite the keeper (G), its own weight sufficient to position a notched part (B3) of its edge immediately opposite a protruding part (V2) side of the vertical slide (VA) with light

oblique.

  The invention is also characterized in that the bo ^ 'tier further comprises a second vertical slider VB with oblique light in the opposite direction to the first slider which controls, when the leaf is in the closed position, the displacement of a vertical rod T , the lower end of which is fitted with a VR lock which

  positioned in a GS floor strike.

  Another feature of the invention, the ground striker GS is provided with a roller GR mounted on an adjustable plate of said striker according to the thickness of the door or gate. Furthermore, the invention is characterized in that the end of the operating member

  OM of leaf P1 is articulated on the sliding member at at least one point C3.

  Still according to the invention, the invention is characterized in that the sliding member OC is an open tube which allows the integration of the fastening elements to the leaf and

sliding.

  Device of the autonomous type characterized in that the sliding member OC is provided with a reduction motor integrated on and / or in the sliding member, reduction motor provided with an opening / closing operating arm produced in at least one part

  whose free end is attached to the pillar secured to the leaf on which is disposed

said sliding member OC.

  The invention is finally characterized in that at the end of the closing stroke of the swing leaf, the horizontal movement of the sliding member OC relative to the leaf P1 begins a movement of the integrated reduction motor by a distance substantially equal to that of the OC sliding member and in the same direction as this one

  Other objects and advantages of the invention will appear better in the description

  detailed which follows and which refers to the appended drawings, given only by way of example, and in which: FIG. 1 is a perspective showing the housing S in rear view with a

  opening showing the pin C2 in the VA slide.

  FIG. 2 is a perspective showing the entire device installed on a

gate with 2 leaves.

  FIG. 3 is a perspective view of the end of the device showing the action of the stop B and its blocking of the sliding mechanism by means of the

VA slide blocking.

  FIG. 4 is a perspective showing more precisely the transmission of the movement to a lock VR via the slider VB and the rod T. - FIG. 5 is a perspective showing the autonomous device, and more precisely the geared motor part in connection with the sliding member (OC) and the connection with the pillar. According to an exemplary embodiment and referring to FIG. 1, a device according to the invention comprises, arranged and fixed on a leaf P1 of a motorized portal with a motorization known as with compass M or of the jack type, an organ OC, sliding longitudinally and horizontally with respect to the leaf P1 of a gate. The sliding is ensured by at least one square Eq 'fixed to the leaf Pldu on the hinge side, and provided with a cylindrical roller. The roller enters the sliding member OC and ensures the positioning of said sliding member OC relative to the leaf P1,

  while allowing horizontal sliding always relative to the P1 leaf.

  The sliding member OC enters a housing S. fixed on the leaf V1 opposite the hinges, through an orifice of shape substantially identical to the section of the sliding member OC and of dimensions greater than this. so as to ensure

  on the one hand the positioning and on the other hand the sliding.

  The housing S is provided with a slider VA with oblique light guided vertically by the walls S1 and S2 of the housing S. this slider cooperates with the element OC by a pin C2 integral with OC which moves horizontally in the light oblique of the VA slide, causing a vertical movement up or down depending on the direction of sliding of the organ OC. In the position of the sliding member tranelated as far as possible in detecting the hinges, a protrusion V2 of the slider VA is encased on the surface B3 of a retractable stop B. articulated in B2 on the housing S. parallel and immediately in contact with the external face of the wall S1 of said box ^ tier S. preventing any sliding of the organ OC with respect to the leaf P1 by imprisonment of the slide VA and consequently of the pin C2 and of the organ

  sliding OC on the said said pin C2 is fixed.

DESCRIPTION

  According to another exemplary prerential embodiment, the blocking of the sliding of the member OC is obtained by direct contact with a surface B1 of the stop B on

  The free end C1 of the sliding member.

  In the two examples of prerentative embodiments, the release of the sliding member OC only occurs at the end of the leaf P1 closing cycle when a protrusion B4 of the stopper B comes into contact with the cover of the keeper G. this contact conditions the pivoting of the stopper B around its articulation B2, which in the first case eliminates the embedding of the protrusion V2 on the surface B3 of the retractable stopper B. and in the other case the contact of the surface B1 with end

free C1.

  This release allows the sliding member OC to enter a keeper G provided

  for this purpose and fixed on the beat leaf P2.

  Concomitantly, the horizontal displacement of the pin C2 in the oblique light of a second slide VB, with oblique light in the opposite direction to VA and arranged as VA in the housing S. controls the vertical displacement from top to bottom thereof and an associated rod T whose end provided with a VR lock is positioned

in a floor strike.

  The strike plate GS is provided with a cylindrical roller GR fixed on a support SG adjustable relative to the strike plate GS. The adjustment makes it possible to adapt the device according to the thickness of the gates by bringing the roller closer or further away in order to optimize the closing on the ground of the portal by the passage of the VR lock between the leaf.

  P1 and the GR roller for locking the gate in the closed position.

  We have thus produced a device according to the invention of the type suitable for

standard engines.

  According to another preDerential embodiment, an embodiment of the autonomous type comprises a reduction gear motor MI fixed to the sliding member OC. The aim is to achieve with a motorization integrated in the OC unit the same functions obtained with the adapted motorizations. The operating arm is composed on the one hand of a part BI called a connecting rod, one end of which is in engagement with the output of the reduction gear motor, connecting rod BI which transmits the circular movement of the reduction motor to a crank MA which is articulated to the connecting rod BI around a crank axis BX, the free end of which is attached, by an articulation MX, to the pillar secured to the leaf on which the sliding member OC is disposed. At the end of the swing leaf stroke, the movement of the sliding member for closing the device as described above generates the displacement of the integrated gear motor by a distance substantially equal to that of the sliding member and in the same direction . The reduction of the gear motor to the sliding member is provided horizontally adjustable so as to adapt the stroke of the leaf depending on the position of the axis of articulation of the leaf on the pillar. Indeed, to obtain the same angular leaf opening, the stroke of the crank rod assembly will be different depending on the position of the axis

  hinge on the pillar.

  The device according to the invention thus contributes to excluding the obligation hitherto made of the bracing of the transmission elements of the movement of the motorization in

  limit switch in order to achieve the best possible effective closing thereof.

  Of course, the invention is in no way limited to the embodiments described and shown which have been given only by way of example. The invention includes all the technical equivalents of the means described as well as their combinations, if these
