Description

The invention relates to the technical sector of doors, gates opening by pivoting and non-sliding.

The opening and closing of doors and gates relative to frames with articulation on pivots is well known and old. The use of locks or devices, locking mechanisms-unlocking the leaves is also known with mechanical systems, electromechanical or remote control with transceivers. The Applicant has itself developed numerous technical solutions in relation. For example, the Applicant has designed and developed in the patent FR 2855551 a complete system integrating the wings and the side frames or stacks with the different functions of walking, security, exchanges and complete automation. In practice, the implementation of this system has proven very satisfactory but costly in terms of cost by limiting the conditions of its operation on niche specific application.

The request for EP 0748316 discloses another example of articulation and safety device.

The Applicant's approach was therefore to think of a simplified design of a device allowing the opening and closing of doors, gates and leaves in optimized conditions, but at lower cost of implementation.

Another object sought according to the invention was to allow an individual wanting to open doors, gates and the like, in case of failure on malfunctions in a simple and fast and almost effortless way.

Another aim sought was to design an installation of doors for doors, gates and the like offering practical and quick installation conditions to implement.

It is also known to provide mechanized opening-closing systems gates gates that are recessed on the ground. These systems require civil engineering operations for their integration and pose many problems in terms of the sealing of the mechanisms due to the flow of natural water or rain.

The Applicant's approach was also to take into account in its search for solutions to these specific questions of in situ placement and sealing.

These and other goals will be apparent from the rest of the description.

According to a first feature of the invention, the hinge and safety device for opening-closing doors of doors, gates and the like is remarkable in that it comprises at least one leaf arranged with a frame having a vertical tubular upright capable of being positioned and articulated on a pivot axis integral with a soleplate associated with the support stack, said frame being arranged in the lower horizontal part with a projecting fixed platform for receiving a receiver articulated link a lock cylinder, said barrel being capable of locking in position said link relative to said platform, and in that said link is capable of being coupled and cooperate with a control mechanism moving the leaf, said mechanism being arranged and fixed from the sole of said stack, and in that the unlocking of the lock cylinder allows uncoupling of the leaf relative to the support stack.

These and other characteristics will be apparent 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 figures of the drawings.

The installation of doors, gates is referenced as a whole by (I) and comprises two leaves (B) which are mounted hinged relative to frames or piles (P) of ends.

Each leaf (B) comprises a frame (1) of rectangular shape or other, made of aluminum profiles or other, with any interior decoration based on panels, solid or openwork, this provision not falling within the scope of the invention. The frame (1) comprises a vertical tubular upright (1a) which is mountable on a pivot axis (2) provided on a fixed sole (3) associated with the stack (P) above. The lower spar (1b) is arranged in its lower part with an open profiled platform (4) projecting and in alignment with said spar. This platform (4) is connected to the spar (1b) of the frame (1) by mechano-welding or other. It is arranged with a shape (4a) protruding flat configuration in the direction of the spar and suitably centered. This protruding shape itself has at the end a notch (4a1) open on the outer side being established in the width of said protruding form (4a). Opposite the notch, said projecting shape has an axis (5) allowing the controlled articulation of a flattened link (6). This, according to the invention, is capable of receiving a cylinder (7) of lock with a bolt (7a) controlled by the key of the maneuver (8). The connection of the barrel on the link is carried out in any appropriate manner by welding or otherwise. The configuration and the size of the bolt (7a) is set to penetrate into the notch (4a1) of the fixed protruding form (4a). Said link (6) has at its end opposite the receipt of the cylinder a rounded shape (6a). Depending on the position of the rod relative to the lower spar of the frame (1), the bolt (7a) of said barrel may or may not penetrate into the notch ensuring a lock or not. The rod cooperates with a mechanism disposed from the sole (3) of the stack (P).

According to the invention, each leaf of the installation can be equipped in the manner described above or a single leaf as appropriate.

In addition, the stack (P) from which is hinged the leaf (B) which receives the aforementioned mechanism. This mechanism includes a fixed sole (3) circular for example. This sole is fixed to the ground in any appropriate manner. This sole comprises in its center a pivot axis (2) around which is mounted a plate (11) circular with rolling means not shown. This plate has on its periphery a plurality of openings (11a), some without receiving pin (12), the set of adjacent pins covering an angular sector of 270 ° or more.

This plate has in a plane concentric with the row of the aforementioned pions an oblong curvilinear slot (11b) limiting in which penetrate two fixed stops (13-14) integral with the fixed sole (3) thus defining a rotation amplitude of the plate in relation to the sole.

The pivot axis (2) is arranged to receive a shaped rod (15) of flat configuration and having at the free end a notch (15a) of rounded configuration to correspond to the complementary end profile (6a) of the link (6). mounted on the wing, in order to obtain a male-female coupling assembly while allowing dislocation as it will be exposed thereafter.

The rod (15) mounted on the pivot axis (2) and in a horizontal plane is substantially below the upper end (2a) of the pivot axis by revealing a tubular free zone (2b) serving as a sleeve engagement and holding the vertical tubular section (1a). Thus, the latter has directly in its lower end portion an inner centering shoulder, so that after positioning, the rods (6) and (15) may be in the same plane in alignment or not according to the operating phases of the installation.

In addition, the rotation of the plate relative to the sole, thus giving the orientation of the leaf of the gate is obtained by the use of an Archimedean screw (16) with variable pitch coupled to a motor unit (M) built into the stack or outside of it.

The helix of said screw (16) is capable of coming into contact and pressing successively on each of the pads associated with the plate by driving the rotation torque generated by the rotation of the plate, and consequently the opening-closing of the wings considered. The battery (P), shown in the drawings with the protective casing and the interior arrangement with the power unit and the control circuits, remote control and others, is established in a manner known to those skilled in the art.

The implementation of an Archimedean screw variable pitch is advantageous in that it allows continuity of movement and successive support on the different pins taking into account the range of movement of the leaves.

Of course, a protective casing of the plate and the sole is provided, but not shown, to protect the mechanisms. Incidentally, as shown figure 4 , the Archimedean screw is rotatably mounted relative to a support (17) integral with the sole (3) with the necessary rolling means, its other end being coupled to the motor shaft. It can be provided the addition of a lubricating means (18) of the Archimedean screw which is mounted on a support rider (19) attached to the sole, the means (18) being an oiled brush or the like.

It is therefore appropriate to set out the operating and use conditions of the opening device by referring to the Figures 5 to 8 .

According to figure 5 in normal situation and smooth operation of the installation, the two links are closely coupled to each other in a perfect alignment. The male-female parts (6a-15a) are nested, and the bolt (7a) of the cylinder (7) is in the notch (4a1) of the form (4a) formed on the lower spar of the frame.

This situation remains during the entire operating life of the installation as long as there are no breakdowns or incidents of any kind that prevent the opening of doors.

In the event of an incident preventing this opening of the door or gate, the operator in the broad sense must then unblock the installation. It is sufficient for him to introduce the security key that he can have permanently with his keys of car or house, to introduce it in the cylinder and turning to raise and to release the bolt (7a) of the notch (4a1 ). After that, a simple pulling of the key to itself in the barrel will cause the pivoting of the rod (6) and its release of the rod (15) uncoupling the locking of the wing (B) relative to the battery (P). ). The operator can thus fully open the corresponding leaf.

Conversely, the same maneuver can be performed when the operating conditions have been found. The closure of the facility can be provided in this same way on a provisional basis as well.

Thus, the device according to the invention has many advantages with great simplicity of operation and implementation, low cost. The structure of the frame (1) can be common to very varied arrangements of decor of the leaves thus allowing an optimization of production of the frames with reduction of their cost.

The simplification of the device is a significant asset and easy handling for unlocking the installation can be performed by anyone without effort.

The invention also offers advantages over the system of the prior art integrated in the ground. In the context of the invention, the device is placed on the ground, without any civil engineering intervention, because of its flat and thin configuration, it integrates perfectly into the environment. The problem of watertightness is solved since there can not be flow by infiltration of water, the protective casing avoiding any stain and oxidation.
