DEVICE FOR DISBRA YA GE REMOTE FROM AN ASSEMBLY
SELF-DRIVING TRAINING DEVICE
SLIDING SUCH AS A PORTAL
The present invention relates to a remote declutching device for an assembly
sliding gate automatic drive system consisting of a motor-reduction unit
/ actuating rack. Gearmotors / racks are most often
used for the closing and opening function of sliding leaves. These
devices generally have the disadvantage of requiring either an annex opening
to the gate to be able to enter the property, and control the operation of the
device, either to have an electrical control system external to the property or to
have a remote trigger for this device; in all
cases,
to date, in the event of a breakdown: electrical supply, gear motor,
failure or loss of the remote control, the user is forced to remain in
outside his property, without the possibility of disengaging the installation. The object of the invention is
therefore to offer the possibility to the user to order from outside his property the
mechanical disengagement of the gate actuation system during opening, from the baleen to this
that he can return home without having to call for a specific intervention in
the aforementioned cases of force majeure.

 This object is achieved by the fact that the remote disengaging device of a motor-reducer / rack and pinion assembly for automation of a sliding leaf comprises an actuation button. ntecanically connected remotely to transmission means, riveted on a support with two inverted plates of the gear motor. to implement the unlocking of the upper plate of the device forming the support of the gear motor which has the effect of releasing this same upper plate and allowing by a simultaneous double displacement longitudinally and in vertical lowering of one of the plates. to decouple the drive pinion from the gear motor of the rack.

 According to another particular feature, the locking means consist of a latch device with an included return spring, fixed by a Z-shaped support on the lower plate of the support of the gear motor. now in the high "engaged" position the upper plate. with an eyelet for fixing the mechanical connection cable.

 According to another particular feature, the actuating button of the device is placed in a protective housing for a cover placed on or in the masonry and comprising "wetting" means.

 According to another particular feature, the gear motor / rack assembly is arranged and actuates. from inside the property, the door leaf or gate. wire rack . sliding.

while the protective housing is located outside the property.

 According to another particular feature, the locking / unlocking latch is incorporated in the lower plate of the support of the gear motor. A Z-shaped support of said latch is fixed welded by one of its ends to a wing of this same lower plate; the other end of this support has a hole allowing the passage of the actuating cable and serving as a stop for retaining the sheath of said cable; the control slider for the locking bolt has at its end an eyelet intended to receive the mounting pin for a jumper fixing this cable, a return spring included in the latch body ensures the automatic return of the bolt to position lock.

 According to another particular feature, the remote declutching device is characterized in that the support (2) is provided with a protective cover, integral with the lower plate (22) of said support of the gear motor (3), and includes a passage for the sheath (41) and the access cable (44) of the locking / unlocking means of the upper plate.

Other particularities and advantages of the present invention will appear more clearly on reading the description below made with reference to the appended drawings of a nonlimiting embodiment in which:
Figure I (plate 1/3) shows a perspective view of a portal assembly
sliding and its geared motor / rack and pinion automation group
remote from a portal pillar including the button protection box
actuation of the unlocking / locking device.

Figure IA (plate 1/3) shows a detailed view of the protective housing of
the actuation command.

Figure 2 (plate 1/3) shows a perspective view of the support assembly
of the gear motor upper plates locked in the drive position
the rack fixed on the gate.

Fig. 2 28 (plate 2/3) represents a perspective view of the support assembly
of the unlocked upper gearmotor, in the lower position of
uncoupling of the geared motor of the rack fixed on the
leaf, leaving the latter free to open manually.

Figure 3 (plate 3/3) shows a sectional view of one of the systems
possible but not limiting of locking / unlocking of the upper plate.

The invention will be described in connection with Figures I to 4 and consists of an automated drive assembly of a sliding leaf such as a gate, consisting of a motor-reduction / rack and pinion actuation assembly Cfig. 1) the first fixed to the ground, the second fixed to the leaf This type of drive assembly has the major drawback of requiring an opening annex to the sliding leaf in order to be able to enter the property in the event of force majeure such as failure or loss of the remote control oti of allane, and electrical condition or of the gear motor which trigger the starting of the motor and the actuation of the leaf by driving the rack fixed to it
Our device therefore consists of two plates (2) arranged one (21) above the other (22) horizontally and being able to move relative to each other simultaneously longitudinally and lowered, interconnected mechanically by locking means (fig. 3), fixed on the lower plate (22) and controlled by remote unlocking by means of a cable (44) sliding in a sheath (41), and integral with a button ( 14) actuation disposed inside a housing (SI) closed by a cover (12). The housing (11) is arranged outside the property closed by the sliding leaf
The housing cover (11) can be locked with a key lock (13). The actuating cable (44) passes through a bore (34) formed in the Z-shaped support (31,33) of the locking device fixed on the lower plate (22) ensuring the retention of the sheath (41) of said cable .

 The end of the cable (44) consists of a stop (48) integral with this cable which drives a jumper (46) formed by a pin (42) on the end of a slide (45). A spring (47) for returning the bolt (49), included in the body of the latch (40) for locking, keeps the upper plate locked in the high position. When the operator remotely pulls the button (14) integral with the cable (44) this has the effect of pulling on the slider (45) for controlling the bolt (49) which unlocks the upper plate (21) and, in simultaneously tracing a slight push on the leaf (1), releases said plate (21) from the support (2) on which the geared motor (3) is fixed, making therefore that, under the action of the double longitudinal displacement and in lowering of the plate (21), the drive pinion (5) of the gear motor (3) uncouples from the rack (4) threaded on the leaf (I) thus making this same leaf free to slide manually.

 The two plates (21, 22) which form the support ig. 2) of the gear motor (3) are made of sheet steel folded in the shape of a U which overlaps one on the other. The lower plate (22) has on its wings two angular oblong slots (23) shaped like an inverted V with uneven branches. The shortest branch corresponding to the high "engaged" position has a negative safety inclination of 5, generating an operating clearance compatible with the normal mechanical operating clearance of a pinion / rack assembly. Said inclination ensures self-stability of the plate by allowing automatic maintenance in the locked position of the guide spacers (24,25) which follow this descending path when the gearmotor (3) is re-engaged.

 The longest branch allows the top plate (21) to be moved and lowered vertically in the "disengaged" position on two guide spacers (24, 25) fixed by screws (26) on the plate (21) allowing it to be moved in the lights (23) of the plate (22). These spacers (24,25) also allow good stiffening of the upper plate (21) A cutout (27) made on the wing (30) of the lower plate (22) in correspondence with an identical cutout (28) made on the wing (29) of the upper plate (21) allows the passage of the locking / unlocking bolt (49). The lower plate (22) ig. 4) has two holes (53) for passage of electric cables at each of its ends of the holes and lights (52) for faration on the ground. The upper plate (21) has the holes and lights (50) for fixing the gearmotor, designed to allow the adaptation of all types of gearmotor used to date in the automation of sliding leaves such as gates, as well as the cutouts (51) which allow the passage of the control and electrical supply cables of the gear motor.

 The locking / unlocking device sfg. 3) of the plate (21) consists of a support (31) made of sheet steel folded in the shape of a Z, fixed by its branch (32) by welding on the wing (30) of the lower plate (22 ), receiving a latch (40) ensuring by a bolt (49) the retention in the high "engaged" position of the upper plate (21). A spring (47) included in the latch body allows the return to the locking position at the bolt (49). the slide ends with an eyelet (45) authorizes the fixing by pin of a jumper (46) for hooking the actuation cable (44) of the bolt (49). The branch (33) of the latch support (40) has a hole (34) allowing the cable (44) to pass through and serving as a stop for retaining the sheath (41) of said cable (44). The support (2) is provided with a protective cover for the locking / unlocking system, integral with the lower plate (22) of said support of the gear motor (3) and comprising a passage for the sheath (41) and the actuation cable (44) for locking / unlocking means of the plate (21).

More generally, the invention relates to a remote declutching device for an assembly (FIG. I) for automated drive of a sliding leaf (1), for example a gate, consisting of a gear motor on the ground. (3) and a rack (4) integral with the
va nia il, Characterized in that it comprises a support (fg. 2) of the gear motor (3) formed by two plates arranged one above the other horizontally (21,22) and being able to move l '' relative to each other simultaneously longitudinally and in
lowering. mechanically linked together by locking means (fig. 3), threaded on the lower plate (22) and controlled by remote unlocking by means
a cable (44) integral with a remote actuation button (14) allowing by
pulling and simultaneously exerting a slight push on the leaf (I) to release the upper plate (21) from the support (2) on which is fixed the gear motor (3) making
as soon as under the action of the double longitudinal displacement and in lowering (fiv. 2 4)
of the plate (21) the drive pinion (5) of the gear motor (3) uncouples from
the rack (4) attached to the leaf (1), thus making the same leaf free to slide
manually.

After troubleshooting, re-couple the pinion (5) of the gear motor (3) with the
rack (4) is made by returning to initial position by simple manual push on
the geared motor assembly (3) and its plate (21) to which it is integral, which has the effect
to replace the said plate in the high "engaged" position and therefore allow
ltentrementement of the rack (4) by the pinion (5) of the gear motor (3), after having
ensured that the teeth of the pinion (5) and rack (4) gears are correctly aligned; the
said assembly will be locked automatically in the leaf drive position (1) by the bolt (J9) of the latch (40) held in position by the spring (47) in the
cutouts (27,28) of the plates (21,22).

Other modifications within the reach of those skilled in the art are also part of
I'm getting.
