Description

SECURITY AND LOCKING / UNLOCKING MECHANISM

  ASSOCIATED WITH A PORTAL OPENING / CLOSING DEVICE

FLAPS.

  The invention relates to the technical sector of swing gates and

similar closures.

  The Applicants have developed a particular opening / closing device for swing gates for which a patent application in France no.

98.03404 has been tabled.

  This device appears in its general economy in Figures 1 and 2 of the application. It will be recalled that this device for opening / closing of swing gates comprises a link and coupling arm secured on the one hand, to the lower part of the hinge post and on the other hand, to a rotating means. disposed at the shaft output of the geared motor group positioned in a fixed construction of the battery type, said means being fixedly arranged with an eccentric profiled shape secured to the end of said arm, and in that the operation of the geared motor group rotates said means rotating by transferring the reciprocating movement back and forth from top to bottom of said link and coupling arm, and thus causing the position changes

  opening / closing of the gate leaf.

  More specifically, there is shown a gate leaf (la) (P), articulated from its lower end along an axis AA parallel and adjacent to a stack (2) defining the framing of the portal with the opposite stack receiving the second leaf (lb). The leaf is pivoted from a point

2 2794788

  upper top (3) and a lower bottom point (4) allowing angular rotation at

  beating.

  The stack (2) is arranged in its lower part to receive the geared motor group (5) which is supported on a support platform (6). The gearmotor, which is present in a vertical plane, is coupled to an angle return device (7) allowing positioning of the output shaft (8) in a horizontal plane. The angle transmission device is fixed to a supporting structure (9) bearing on the ground. The bearing structure (9) is capable of ensuring, in addition to positioning and fixing one side of the bevel gear, but also of a pair of gears (10-11) allowing the speed reduction generated by the gear motor. The small pinion (10) is thus mounted at the end on the output shaft of the gearmotor assembly (5). The large pinion (11), which is mounted underlying, is mounted on another rotating shaft (12) arranged by means of bearings (13) suitable between said bearing structure (9) and a complementary support plate (14) or equivalent integrated in the battery. The association of the gear allows a reduction of the speed at the output of the gearmotor shaft, in order to transfer this movement to the output speed of the leaf. The large pinion (11) is arranged on its visible lateral face (1a) with a projecting strip (15) profiled in rectangular configuration and established on part of the diametrical axis of said pinion. Said projecting strip (15) has a cutaway (15a) at one end to form a zone for fixing an articulated link and coupling arm (16). Said protruding shape (15) is therefore

  likely to follow, by its fixed connection to the pinion (11), the rotation of the latter.

  The reduction ratio between the small (10) and the large (11) pinions is established so that said projecting strip is in the horizontal position in the fully open position of the leaf, or in the fully closed position of this

  last, but in reverse 180 position.

3 2794788

  Thus, this is the function of the gearmotor group and thereby the operation and rotation of the couple of pinions or turning means in general

  which will cause the movement of the leaf in opening / closing.

  To do this, the link and coupling arm (16) is secured, on the one hand, fixedly to said protruding shape (15), and on the other hand, to the upright (17) of the leaf (1). More particularly, said upright (17) of the angle of the leaf is arranged in its lower part with a screed shape (18) U-shaped whose opening (18a) is located opposite the control means. This screed shape (18) is fixed by welding or otherwise to said upright (17) by constituting a rigid assembly. In its rear part, said yoke is crossed by an axis (19) of transverse connection. The link and coupling arm (16) according to the invention ensures the transmission between the projecting shape (15) established on the large reduction gear (11) and the yoke, and therefore with the end upright (17) of the leaf, thus allowing, during the rotation of the pinion (11) under the effect of the motor, to follow an alternating up / down movement ensuring the radial pivoting of the leaf, that is to say its opening or closing. Said link and coupling arm is thus subjected to an up / down reciprocating movement

  generated by the position of the protruding shape (15).

  The opening / closing device of the swing gate as described in French patent application 98.03404 is particularly reliable with

  the use of a low power gearmotor group.

  If this device controls the opening / closing of the gate leaves, it does not have any effect as to the security of closing the leaves relative to a pivot point arranged on the ground located in the middle part of the frame opening of the gate and allowing to lock in the closed position

said leaves.

4 2794788

  The Applicants' approach was therefore to reflect on the implementation of a complementary security mechanism, making it possible to lock the leaves in position when closed and unlocked during the opening phase. As part of their research, the Applicants were able to examine the establishment of a security mechanism independent of the device

  opening / closing of the gate leaf.

  Various solutions have been studied, either by manual control means, or by mechanical means controlled remotely or manually. Known for gate and door closings are mechanisms with rods associated with the door handle, these mechanisms including movable locking bolts and allowing locking or unlocking of the door of the apron according to the action on the operating handle. Such mechanisms have been described by one of the French patents of one of the

Applicants no. 2711175.

  This type of solution was not selected, because the implementation proved complex, required a modification of the existing batteries already arranged

  specifically for the aforementioned opening / closing devices.

  In addition, the obligation to have two separate orders has proven to be

inconvenient for the user.

2794788

  The Applicant's approach was therefore oriented differently by trying to use the functionality of the opening / closing device defined in French patent 98.03404, to develop a more complete automation ensuring the new functionality of search for security and locking in relation to

  at the pivot point located in the opening of the portal frame.

  This research led to the specific implementation of a mechanism integrated in the lower horizontal part of one of the leaves by presenting means integral with the closing / opening device of the leaf and means cooperating in the locking / unlocking position with the pivot point located in

  the opening of the portal frame.

  According to a first characteristic, the security and locking / unlocking mechanism associated with a device for opening and closing swing gates, said device being of the type comprising a link and coupling arm secured on the one hand to the part lower of the hinge amount of the leaf and on the other hand, to a rotating means disposed at the outlet of the shaft of the geared motor group positioned in a fixed construction of the battery type, said means being fixedly arranged with an eccentric profiled shape secured to the end of said arm, and in that the operation of the geared motor group rotates said rotating means by transferring the cyclic back-and-forth movement from top to bottom of said link and coupling arm, and thus causing changes in position opening / closing of the gate leaf, said security mechanism being characterized in that it includes an integrated transmission means connecting intermediary in the form of cable, rod, disposed along the horizontal lower part of the framing structure of one of the leaves, said transmission means having a first end fixed and secured to the link and coupling arm of the operating device in

6 2794788

  opening / closing of the gate, thus being subject to back and forth movements

  comes from bottom to top and top to bottom of said arm as a function of the gate opening / closing situation, the other end of the transmission means being arranged with movable and articulated anchoring means capable of cooperating and surrounding the pivot point of the portal framing opening, the position of said movable anchoring means allowing said gate wings to be locked in the closed position and / or to unlock the point

pivot for opening the gate.

  These characteristics and others will become clear from the rest of the

description.

  In order to make the object of the invention more concrete, it is now described

  in a nonlimiting manner illustrated in the drawings.

  The implementation of the gate (P) and its two leaves (la, lb) with the opening / closing device described in French patent 98.03404 has been described previously This device participates in the development of the present invention and the

  numerical references are the same.

  The security and locking / unlocking mechanism of the gate leaves, includes an intermediate transmission means of connection in the form of a cable, rod, arranged along the horizontal bottom part of the framing structure of one of the leaves (the ), said transmission means having a

8 2794788

  first end fixed and secured to the link and coupling arm (16) of the device for operating the opening / closing of the gates, thus being subject to back-and-forth movements, from bottom to top and top to bottom of said arm depending on the opening / closing situation of the gates, the other end of the transmission means being arranged with movable and articulated anchoring means capable of cooperating and surrounding the pivot point of the opening for framing the portal , the position of said movable anchoring means allowing locking in the closed position of said gate leaves and / or

  unlocking the pivot point for opening the gate.

  Said intermediate transmission means accompanies the movement of the aforementioned link and coupling arm (16), and as a function of the position relative to the torque of the pinions (10, 11) of the projecting strip (15) secured to the end of said arm, the safety and locking mechanism must be actuated

or not.

  Referring to the figures of the drawings, the intermediate transmission means (30) is a cable having a certain rigidity, being of great length, to be engaged along the horizontal lower part of the frame structure of a leaf. or internally in it by being integrated in

  the volume of the constituent section or by being guided outside it.

  As shown in the drawings, the transmission cable enters the interior volume of the profiled structure of the leaf frame, and comes out

  by its ends thereof by suitable openings.

  A first end (30a) of the transmission means is fixed to a profiled flange (31), itself integral and fixedly attached to the arm of

  connection and coupling (16) and to the upright (17) of the leaf associated with it.

9 2794788

  Said flange thus has an L-shaped configuration with a straight wing (31a) welded radially to the upright (17) and a curvilinear branch (3 lb) attaching to the arm (16) by welding or otherwise. This curvilinear part serves as a guide at the end (30a) of the transmission cable. A tab (32) attached or formed on the puddle has a slot or opening (32a) for passage of the end of the cable which is arranged at the end in the form of a bead (30b), for

  come into abutment against the face facing the tab.

  It is thus understood that the up-and-down movements of up and down of the arm (16), depending on the position of the leaves of the gate, will cause a pulling or loosening effect of the transmission means, and this with regard to its other end (30c) which is likely to cooperate by surrounding or not

  with a pivot point (33), depending on the operating phases.

  The configuration of the flange and its curvilinear part is likely to

  allow without difficulty and without deterioration a draw of the transmission means.

  The other end (30c) is arranged and operates to cooperate with the pivot point located in the opening part of the frame of the gate, so as to either bypass it to ensure locking in position, or for the

  release during opening phase.

  The pivot point can be established in different configurations. A few non-limiting examples will be given thereafter.

  works means capable of cooperating with the latter.

  In any event, the pivot point is shaped as a peg anchored to the ground (Figures 1, 3 to 6) or as a rectangular plate (Figures 7 to 10) while being fixedly positioned. This pivot point is likely to be surrounded

2794788

  or bypassed by the anchoring means located at the end of the transmission means. This pivot point is fixed and resting on the ground or on a plate itself fixed to the ground. A counter-abutment stop (51) is situated in a plane close to the pivot point to allow the stop of the second leaf (lb) in alignment with the first

  in the gate closing phase.

  Referring to Figure 3, the means of cooperation with the pivot point

are the following.

  The horizontal lower part of the frame structure of the leaf (la) is capable of receiving a bar (34) of great length and projecting from said

  leaf, and this to come into contact with the abovementioned abutment stop (51).

  This bar (34) is fixed in any suitable manner by gluing, screwing or the like to said bottom part. This rectangular section bar for example receives a fixed member (35) allowing the fixing, the connection and the articulation of a reel (36) of the end of the transmission frame (30) and of a lock (37) , thanks to an assembly on a nut axis (38) allowing the connection and the holding to be ensured. The reel-forming part (36) is established in a half-moon configuration with a groove (36a) for passage and guide of the cable. The reel

  has an opening (36b) for the passage of the axis (38).

  More particularly the reel (36) has an external overflow a tab (36c) arranged with an opening (36d) allowing the.-ssage of a cable and forming cable stop, the latter comprising a bead at its end.

1 1 2794788

  The lock (37) is in the form of a hook with an opening (37a) allowing the insertion of the nut axis (38), the hook form being

  likely in the event of articulation to surround the pivot point.

  A return spring (39) is arranged with an integral end (34a) of a fixed point of the bar (34) and a fixing point (37b) on the latch. When the locking is carried out on the pivot point, the aforementioned spring is in a situation of maximum tension. This situation corresponds to the lifting up of the link and coupling arm (16) disposed on the opening means.

gate leaves closed.

  In the gate opening phase, the arm (16) is lowered, removing or reducing the cable tension, this causes the spring (39) to relax, which brings the retractor-lock assembly back by elastic return, by the axis connecting them. The lock moves away from said pivot point by releasing it as well as

  shown in Figures 5 and 6 of the drawings.

  It is now necessary to set out the methods of execution of the variant shown in FIGS. 7 to 10. In this case, the pivot point is established in the form of a rectangular profiled projection (40). The mechanism then includes a finger (41) which is associated with the end of the transmission cable (30) to follow a translational movement in the direction of said cable. To this end, the lower part of the leaf receives a sheath (42) capable of internally receiving a movable cylinder (43), the assembly being traversed longitudinally by the transmission cable. The cylinder is mounted with an elastic displacement capacity according to a preset stroke and limited by stop means not shown. Inside said sheath is disposed an elastic return means (44) which bears between on the one hand one of the bottoms of the sheath and the bottom of the cylinder. Said finger (41) is fixed in a plane perpendicular in thickness and to the end of the cylinder. The finger has an opening (41a) allowing the passage of the cable and the retention and fixing of the latter by a bead (30d) bearing against the face of said finger. Referring to Figures 7 to 10, the operation is as follows. In the closing phase of the gate leaves, the link and coupling arm (16) is in the high position with a pulling effect on the cable, which brings the cylinder back inside the sheath. The finger is then in regar4l of the pivot point thus ensuring a locking of the leaf. When the coupling arm (16) is lowered, the cable is released and by the spring relaxation effect, the cylinder is moved according to the arrow shown, driving the finger which is then

  clear of the pivot point. The leaf can then pivot as shown in Figure 10.

  In the variant embodiment of FIGS. 11 and 12, the lower part of the leaf receives a fixed profiled plate (45) having a bottom face (45a) secured and two oblique wings (45b) oriented divergent. An axis of rotation (46) is fixed on the plate allowing the fixing of a squared wing (47), one end (47a) of which has a movable finger (48) capable of coming opposite the fixed pivot point (49). The transmission cable (30) is secured to the pivot finger while a spring (50) is fixed at one end to one of the wings of the plate and to the movable finger. In the closed leaf position, the link and coupling arm (16) keeps the cable pulled, and the spring (50) is in the extension phase. The lowering of the arm (16) causes the cable to loosen and the spring to relax, thereby causing the finger (48) to pivot and release relative to the pivot point and thus allowing the gate leaf to pivot and open. The axis of rotation (46) mounted on a fixed ring (46a)

  allows pivoting of the wing (47) and therefore of the finger (48).

  The advantages of the invention are important. The automated system allows the gate to open or close in a single operation in a single operation. The transmission cables can be rigid to facilitate the execution of movements. The implementation of

  security mechanism does not result in high costs.

  Another characteristic resides in the reversal of the movements and speeds of the safety mechanism and the opening / closing device.

  well said. The pinion torque (10-11) has a constant speed of rotation.

  The wing is driven at zero speed at the start, maximum in the intermediate phase, and zero at the finish. This safety mechanism works in reverse, maximum at the start, zero in the middle of the race, maximum at the end of the race.
