Abstract

The device has a mortise lock with a flat metallic control rod having segments fixed free in longitudinal translation on multiple panels constituting a gate integrated to a sectional garage door. The transmission of movement to the segments is carried out by the introduction of a cylindrical dog pilot point, made in upper and lower parts of the lock, into an orifice made in an end of the segments. An elastic connection between the segments disposed on the panels located above and below the panel integrating the lock is made by a spring (R) guided by longitudinal profiles (PR1, PR2).

According to a first embodiment and referring to the figure 1 a device according to the invention is installed on the integrated door of a sectional garage door and provides a top and bottom closure of said door.

According to this first embodiment provided with a lock S1 of the longitudinal transmission type of movement to the upper and lower rods, a device according to the invention comprises sections of flat metal rods fixed free in longitudinal translation on the edge of the multiple panels that is the integrated door of a sectional garage door. The plane of the sections of rods being parallel to the edge of the panels and immediately facing.

The mortise lock S1 is integrated in a panel substantially in the middle of the total height of the gate. The transmission of the movement to two sections of rods arranged above and below the trunk of the lock is done by the introduction of a cylindrical nipple made at the top and bottom of the lock S1 in an orifice made in one end sections of rods. The translation of each of the two sections is controlled by the locking / unlocking of the lock, which raises or lowers the cylindrical nipples in a plane parallel to the edge of the panel on which is fixed the lock, and thus the rod sections connected to said lock. The other end of the two rod sections is connected respectively to a rod section which is fixed free in translation on the edge of the panel immediately above or below the central panel incorporating the lock.

An elastic connection allows the transmission of the movement of the lock S1 to the sections of rods mounted on the multiple panels.

This elastic junction is of compression spring type R, each loop-shaped end of which is hooked on a tab PP1 or PP2 folded at 90 ° and made on the end of the rod sections, TT1, TT2, intended to receive said elastic junction. . The loop of the spring R is preferably offset tangentially to the body of said spring R to allow maximum attachment of said spring loop in the lug PP1 or PP2 opposite.

The spring R is traversed over its entire length of at least one metal wire bent at each end to prevent the elongation of the spring R. Another variant is to pass through the spring R along its length with a thin cable provided at each end of a loop crimped on said cable, each loop respectively catching on the tab PP of the end of the rod section opposite. <

The spring R is guided in translation by a longitudinal metal profile, PR1, and a longitudinal profile PR2, U-shaped, which cover the spring R over part of its length.

These profile, PR1, PR2, comprise a base which is parallel and offset from the plane of the rod sections. Two longitudinal wings of said profiles, PR1, PR2, folded on either side of them at 90 °, return to the rod sections TT1, TT2 without contacting to avoid friction. These longitudinal profiles are each traversed in their central part by a cylindrical sleeve DC previously fixed on the edge of the panel concerned, cylindrical sleeve machined on one end of a groove which allows the mounting of a circlip bearing on the base of each profile (PR1, PR2) to fix them. A variant not shown allows the clipping of each profile PR1 or PR2 on the DC bushing by cooperation of a circular protrusion formed on said DC bushing with a slot formed on each of the longitudinal flanges of said profiles PR1, PR2.

The fixed position of the longitudinal profiles PR1, PR2 with respect to the panels to which it is attached is obtained by cooperation between a tab PP2 depending on each section of the rod opposite each longitudinal section, the tab bent at 90.degree. the end of the oblong hole opposite the hinge axis of the panels concerned, which fits between the flanges of the profiles PR1 and PR2, and the DC socket associated with retaining circlips. Thus positioned, these profiles guide the spring R virtually to the level of the axis of rotation, an angular section of their end allows the spring R to bend when the panels rotate under the action of the opening / closing of the garage door.

Each DC bushing is further machined with a groove opposite that made for the circlip, which allows the translation of the associated rod section in an oblong hole formed therein.

According to another embodiment provided with a lock S rotatably transmitting movement to the rods up and down and referring to the figure 5 , the device comprises support portions rods, metal profiles bent sheet U-shaped, longitudinal, having at each end a perpendicular return RT between the wings of the U machined return a circular orifice OC.

The rod support parts are fixed on the edge of each hinged longitudinal panel component integrated gate.

Each bead support portion is provided with a portion of hollow square section rod T1 which exits through the orifice OC of each return RT at each end of the bead support portion.

The immobilization in translation of each rod portion in the associated rod support is provided by two pins passing through the bead portion at each of its ends, the projecting portion of each pin immediately contacting the inner face of each RT return folded sheet.

A mortise lock case is attached to an intermediate rod support. This lock case is provided with a PC central bolt and outputs of up and down rods with opposite longitudinal displacement and in the axis of the parts of rods T1.

Each rod exit is continued by a portion of cylindrical rod PTC which is provided on its end opposite the attachment with the rod outlet of a cylindrical pin TT passing right through the cylindrical rod part, pin whose two ends protruding penetrate the helical lumen H of a rotating cylindrical PH sleeve. each of the two cylindrical bushings PH is fixed on the rod support in order to allow only the rotational movement obtained by raising or lowering the cylindrical pin TT in the helical bore H.

Each rotating bush PH is continued from a portion of a hollow square bead portion that exits through the orifice OC of each return RT, as described above.

The connection between the multiple parts of rods each associated with a rod support is provided by a ring J, square, solid, rubber with a section slightly smaller than the inner section of each rod, to allow the angular displacement of the panels. relative to each other while maintaining immobilization in rotation of the parts of the rods relative to each other. The immobilization in translation of the ring J is ensured by a lock washer which is introduced at half the length of said ring J, washer which is supported by the own weight of the ring J on the end of the bead portion located in below.

At the end of each high or low rod, each composed of several bead parts, is fixed a pinion gear PG to the right of which the axis of rotation coincides with that of the rod T1.

It cooperates with a rack forming the tail of a PX bolt provided to condemnation perpendicular to the edge of the door to enter a keeper provided for this purpose and fixed opposite the door at the top and bottom of it. on the edge of the panels constituting the garage door.

The locking of the lock, when the door is in the closed door position ie vertical door panel, generates the opposite vertical translation of the upper and lower rod outputs which determines the rotation of each cylindrical sleeve PH which transmits the rotary movement at each bead portion through the rushes J.

The PG gear fixed rotatably at the end opposite the lock box of each part of the upper and lower rod furthest from said lock box allows the translation of a top bolt and a lower bolt by cooperation of a machined rack. in the bolt tail, translation that allows the locking of each bolt up and down in a keeper located opposite each of said bolts.

We have thus produced a device according to the invention.

Of course, the invention is not limited to the embodiments described and shown which have been given by way of example.
