FLAP GATE INCLUDING A MECHANISM OF

  SECURITY AND LOCKING AND / OR UNLOCKING

  ASSOCIATED WITH A MANUAL SECURITY DEVICE

  The invention relates to the technical sector of swing gates and

similar closures.

  The applicants have developed a device for opening / closing swing gates described in patent FR No. 9803404. This device comprises a link and coupling arm secured on the one hand to the lower part of the hinge post of the leaf. and, on the other hand to a rotating means arranged at the output of the shaft of the geared motor group positioned in a fixed construction of the battery type. This rotating means is fixedly arranged with an eccentric profiled shape secured to the end 1 of the arm. The operation of the gear motor group rotates the rotating means by transferring the cylindrical movement back and forth, from top to bottom, of the link and coupling arm and driving the

  changes to the leaf opening / closing position.

  If this device controls the opening / closing of the gate leaves, it does not have any effect on the security of the leaves closing with respect to a pivot point placed on the ground and located in the middle part of the frame opening. gate and allowing to lock in

  closed position of said leaves.

  In a first step, the applicants have thus developed a complementary security mechanism making it possible to lock the leaves in position when closed and / or locked during the opening phase.

  Studies and research have resulted in an original concept described in French patent application No. 99/07694. First of all, use is made of an intermediate transmission means of connection in the form of a cable, rod, known per se, disposed along the horizontal bottom part of the framing structure of one of the leaves or internally therein. by being integrated into the volume of the profile. This transmission means has a first fixed end secured to the link and coupling arm of the gate opening / closing operating device, thus being subjected to the back and forth movement, from bottom to top and from top to bottom. , arm in

  depending on the opening / closing situation of the gates.

  According to the originality claimed in said French patent n 99/07694, the second opposite end of the transmission means is arranged with mobile and articulated anchoring means capable of cooperating and surround the pivot point of the opening of the frame of the gate, the position of the movable anchoring means allowing locking in the closed position of said gate leaves and / or locking the pivot point by opening the gate. Said second end is arranged and operates to cooperate with the pivot point in order either to bypass it to ensure locking in position, or to release it in the event of the opening phase. Several exemplary embodiments have thus been described allowing the implementation of this concept. This is operated by

  applicants and thus satisfactorily meets needs.

  The applicants nevertheless continued their studies and research to optimize this security mechanism. A first line of research was to simplify the opening / closing drive part of the leaves by a specific choice of components of lower cost and facilitating assembly of the assembly. A second line of research was to design

  additional a manual safety device associated with said mechanism and allowing in the event of a power failure or other incidents to unlock

  manually the installation to allow the leaves to open.

  Based on these objectives, the applicants have thus brought new solutions which perfectly meet the needs with an improvement in security, a reduction in costs while maintaining a

  excellent operating reliability.

  According to a first characteristic, the swing gate including a security and locking and / or unlocking device associated with an opening / closing device of the type comprising a transmission means integrated along the lower part of the structure. framing of one of the leaves, one end of which is fixed and integral with a means of connection and coupling of the device for operating the gate's opening / closing, associated with a driving means, and the other end of which comprises means capable of cooperating with a fixed means disposed on the ground in the central part of the opening, said portal being remarkable in that one of the leaves allows in its hollow horizontal lower profile internally the guidance and the free movement and

  controlled by a slide cooperating with the opening mechanism-

  closing of the wing, said mechanism being disposed in the framing pillar, and comprising a mounted link associated with the engine block and driven in a rotational movement of the order of 270, said link being secured to the slide, and in that said link takes the end positions of closed dead center A and open dead center B with an intermediate dead center C corresponding to the maximum extraction of the slider whose narrow profile and its position at 45 opening, and in that the front end of the slide has a stud capable of cooperating and

  to engage in a protective rail, and to disengage from it in the position of maximum retraction of the slide, and in that a manual safety device is disposed at the front along the profile of the leaf including a lock and an articulated operating handle capable of cooperating with the stud. These and other features will become apparent from the

description which follows.

  in which the central stud is in the unlocked position.

  1 5 In order to make the object of the invention more concrete, it is now described in a nonlimiting embodiment illustrated in the figures

drawings.

  The installation conventionally includes pillars (1) from which the leaves (2) of the closing portal are hinged and held. FIG. 1 shows a single pillar with an associated leaf including the locking / unlocking and safety mechanisms according to the invention. The other pillar and the other leaf are simply arranged to receive the means of articulation and transmission of the movement in opening / closing in operation in close relation

  with the mechanism allowing the movement of the first leaf.

  According to the invention, the leaf comprises in its horizontal lower part a long profile (3) hollow internally

6 2811701

  authorizing the guidance and movement of a slide (4) cooperating with the mechanism (5) allowing the opening / closing of the leaves. This mechanism is arranged in the lower part of the pillar (1) and comprises the following elements. A connecting rod (6), of flat section for example, is mounted articulated on a vertical drive axis (7) associated with the engine block (8) located in the pillar. This rod is thus driven in a rotational movement at an angle of about 270 as will appear

  in the following description and which corresponds to the movement

  leaf opening / closing. Said connecting rod has at its end opposite the connecting rod axis, a bore (6.1) allowing the positioning of the axis (9) of the slide and allowing the fixing thereof by means of an attached ring (10) or welded at the end (4a) of said slide (4). The pivoting of the connecting rod following the command action of the engine group thus causes the pivoting of the leaf in which the slide is freely integrated. Underlying the connecting rod is arranged on the ground or at the bottom of the pillar, a rectangular stop (11) in function is to ensure locking in position of the axis of the slide when the leaf is closed. There is shown by (12) the hinge axis of the leaf of the portal. Said slide (4) is established for movement freely but in a controlled manner inside the profile of the leaf frame by suitable means of the roller type or the like. Its displacement is obtained by the

  control of the engine group and association of the slide with the link.

  According to this particular and original arrangement of the invention, the link is driven by a movement in rotary displacement of the order of 270 from a point A corresponding to the closed dead center and to the closing of the gate, up to a point B of the open dead center corresponding to the opening of the gate leaf. Due to the position of the slide axis on the link, said slide will be driven in a back and forth movement of extraction or penetration of the receiving section with a passage to a

7 2811701

  intermediate dead center (C) located halfway between the end points A and B and corresponding to an intermediate position of opening the leaf at 45. Thus, with reference to Figures 6, 7 and 8 which illustrate the operation and movement of the slide. In the closed position of the gate, the slider is located entirely inside the receiving profile of the leaf frame, Figure 6. In this phase, the slider is located at 45 relative to the axis of the link, and l of the slide axis

  located behind the stop (11) in the locked position.

  In the intermediate open position, said slide is in the maximum extraction situation and is in the same plane as the link underlying it (see FIG. 7). In this case, the axis of

  slide is released from the stop (11).

  i5 When the gate is fully open, the slide is

  again entered into the profile and is located 90 from the plane of the link.

  According to another arrangement of the invention, the front end (4b) of the slide (4) is arranged with a means (13) in the form of a stud which projects beyond the profile by its underside thanks to a light (14 ) oblong arranged on said face. The length of this oblong light is adapted to the travel of the slide. Said piton (13) integral with the front end of the slide has at its free end a disc or plate (15) welded and attached which projects beyond the axis of the piton by constituting a locking means in position relative to a rail ( 16) U-shaped with ends (16b) folded horizontally revealing a slot (16c), constituting a sheath for receiving and guiding said piton. This rail (16) is fixed to the ground in the axis of the gate in the closed situation. This rail (16) has a beveled end (16a) facing the

8 2811701

  direction of movement of the slide to allow the piton to escape

  under certain operating safety circumstances.

  If reference is made to FIG. 6 corresponding to the closing of the leaf, the following functions are thus obtained: locking by closed dead center (A) of the connecting rod with locking by blocking the axis of the slide behind the stop, and locking in position of the bolt associated with the front end of the

  slide in the receiving rail preventing any lifting of the gate.

  Referring to FIG. 7, the rotation of the connecting rod causes the portal to rotate by means of the slide and the movement of the latter partially releasing it from its receiving section and allowing the

  release of the peg from the safety rail.

  1 5 If we refer to figure 8, the link is in neutral position

  open (B) with gate opening.

  It is now necessary to refer to another important arrangement of the invention with the manual additional safety device, allowing the unlocking of the gate as shown in Figures 9 to 13

drawings.

  This device comprises two main members, namely a lock (17) and a specific operating handle (18). Said lock is fixed on the inner edge of the profile (3) of the flap framing framework at a location near the end of the latter. The latch thus has a bolt (1 7a) which is capable of projecting downward to ensure locking of the operating handle or its release. Said lock is

9 2811701

  controllable from inside or outside using any means

  suitable such as key, operating button and other.

  Said operating handle (18) is specific. It is mounted articulated on an axis (19) integral with the profile of the framing framing frame and it is arranged with two opposite gripping zones (18a - 18b) thus allowing its control by the operator from the outside or from inside the portal. In its central part (18c), the operating handle is arranged with a heel in the form of a yoke allowing the integration and articulation of a connecting rod (20). The end (20a) of said

  rod is mounted around the stud (13).

  The body of the link has an oblong opening (20b) of great length corresponding to the maximum travel of movement of the peg during the movement of the slide. The operating handle and the associated link are subjected to a compass movement during the unlocking actions of the manual safety mechanism. To this end, when the operator wishes to maneuver the gate by means of the manual safety device, it suffices to act on the lock by raising the bolt which is located in front of the operating handle, by releasing the latter. The operator can then grasp said handle by one or other of its gripping zones. It then causes the articulation of the handle and the opening of the compass by the associated link (20). Said link causes, from the bottom of its oblong lumen, the displacement of the pivot point, its drive and its release relative to the safety rail. It is then possible for the operator to open the gate. The displacement of the pivot point causes the displacement of the slide and therefore the rotation of the rod of the

  locking and unlocking mechanism.

  Replacing the device is simple. Just perform a reverse operation. In this case, the piton is not driven, only the closure of the wing allows the said piton to be replaced and its position in the rail.

guidance and security.

  The device of the invention is simple and very reliable.
