Abstract

The present invention relates to a sealed, continuous and finger-pinch-proof articulation device, designed to articulate between them, sectional door panels, or any other panels with a thickness greater than 20 mm. This hinge system is made up of 2 articulated profiles (P1) and (P2), each comprising a series of 3 teeth, (Dts.1) and (Dts.2) interlocked in stress, under the elastic force of a lock of extruded aluminum hinge (V), fitted with wings (A1) and (A2), retracting into a drawer, in profiles (P1) and (P2), according to the angle of the joint . This principle allows the elimination of a flexible seal. This continuous hinge process has qualities of speed of implementation, thanks to a concept of ultra fast assembly by gluing, in the manufacture of the product; and also by a snap-fit mounting method, to the installation of the product on the installation site. This device according to the invention is particularly intended for the manufacture and installation of garage doors, of the sectional type.

Description

DESCRIPTION
HINGED, CONTINUOUS AND FINGER-FINGER HINGED DEVICE.

CONCLUDED POI: R ARTICULATE SECTIONAL DOOR PANELS, OR ALL OTHER PANEL OR DOOR PANELS, [1BITUALLY
USED IN THE HABITAT.

 The present invention relates to a continuous joint device, designed to articulate the panels between them, sectional garage doors, or other panels of thickness greater than 2Omm, the specifications of which require on the French market 5 qualities specific.

 The main qualities being imposed by the French standard: NFP 25362.

I) - Quality that is attractive to the safety of persons: This implies that the anti-fingertip feature must be ensured in the articulation of the panels between them ') - Quality of airtightness and watertightness between panels, at least when the joint is joined, ie. vertically aligned panels in closed door position! - - Quality of low resistance to the joint, despite the significant load on the joints of a sectional door. This quality makes it possible to go in the direction of safety, avoiding the use of a high power motor, source of crushing force too
Important at closing, and prohibited by the standard cited above.

4) - Excellent resistance, door closed, to the wind pressure, and great inertia of the panels to obtain an arrow less than 1/200 e ", when the deck is pushed horizontally between the 2 supports, constituted by the horizontal rails.

5) - Good alignment accuracy when mounting the hinge pins, a great ease and speed of mounting the panels together, so that the assembly time of the panels on the site is as short as possible.

The present invention optimally assumes the qualities thus enumerated and required in the specifications of the articulation of a type <(sectional) door, but it also allows other applications in the habitat, and in particular:
Wherever the safety anti-finger-grip, and where the tightness at all angles of the joint, will be required, as in the case of
- The retractable roofing roof hinge.

 - The articulation of mobile vertical partition panels.

 - The traditional door apron joint.

 - The articulation of sliding garage door panels.

 - The articulation of shower partition panels.

 In addition, there are other methods of continuous joints and anti-finger clamps, such as the sf stème developed in French Patent No. 90-08426, but this system is not really applicable. only for the panels of a sectional door, where the vertical load on the hinges is permanent and necessary.

 Thus, with the principle of the French patent nC9008426, a vertical joint would not be possible, as in the example of a sliding door, where with this principle of articulation, a joint extension problem would be in the upper part of the gate, and a compression problem of the seal at the bottom of the gate.

 In the present invention, although this device is perfectly adapted to withstand the constraints and the specifications of a sectional door (horizontal articulation excluded), it is also suitable, and performant in all positions of articulation, including in the vertical position.

The present invention is based on a permanent dynamic sealing concept, made from three extruded aluminum profiles. (P 1), (P 2) and (V), fig 1, without the addition of a
Flexible seal. The profiles (Pl) and (P2) each comprise a series of 3 teeth, (Dts. I) and (Dts.2), of cylindrical shape, nested under stress, under the elastic force of a hinge lock. The hinge latch profile (V) is equipped with 2 ends (C1) and (C2) seml-tubular, forming axes of rotation concentric with the centers of rotation (01) and (02).

 The teeth (Dts.l) and (Dts.2) work in permanent stress on a support line, between top and bottom of the tooth, thus generating a principle of micro creep of the metal throughout the running phase of the joint , and making follow a multitude of lines of tangency, in constraint, which are in fact sealing lines, metal against metal. figs 2. 3. 4. 5.

 This device thus makes it possible to obtain a very economical sealing system, combined with great reliability over time, given the absence of a flexible seal. This seal is always a wear part, because of its deformation over time.

 In addition to generating a permanent dynamic sealing principle, this method also makes it possible to form a continuous hinge with low mechanical strength, thanks to its rolling joint technique, between the top and the bottom of the tooth. Principle that could be likened to a wheel of very large width equipped with teeth, at the end formed in an arc coming from tangent the ground on a continuous line, which can reach lengths of more than 8 meters.

Despite a heavy load on this wheel of great width, and whose rotation is characterized by low mechanical strength. figs 2. 3. 4. 5.

Finally, to come back again to the principle of permanent dynamic sealing, it is
Important to specify that this articulation comprises a line of tangency, forming a sealing line between the profiles (Pl) and (P2), framed in a symmetrical manner and parallel by 2 other sealing lines, the whole constituting a chamber of decompression (Cham 1), see figl.

 This decompression chamber is constituted by the U-shaped spring of the hinge latch profile (V), and closed by the interlocking tangency line of the profiles (P1) and (P2), and by the other 2 sealing lines. parallel, formed by stress bearing lines, of the two ends (C1) (C2) of the hinge lock (V) on the concentric parts of the profiles (Pl) and (P2) of centers (01) and (02) This chamber assumes an air and watertight function, by playing a role of air decompression, which could (pushed by a very powerful wind) infiltrate through the toothpipe system. articulation cited above. This air or water would then be a prisoner in this baffle (Cham 1), which would be a new obstacle to overcome, admitting that the air at this stage, is not yet decompnmated.

After the decompression chamber, (Cham 1), there are 7 other decompression chambers of greater volume (Cham 2) and (Cham 3), to complete and perfect the decompression of an air pressure, which would have was able to cross the first room (Cham 1) The rooms (Cham 2) and (Cham 3) are delimited by:
- the wings (Ai) of the hinge lock (V) for (Cham2), and (A2) for (Cham 3),
the inner zone of the profiles (Pi) for (Cham 2), and (P2) for (Cham 3),
- and by the external meter of (Cham 1) for (Cham 2) and (Cham 3).

 This succession of 3 sealing chambers confers and confirms to this method of articulation the continuous hinge characteristic, to the concept of dynamic and permanent sealing.

 This waterproof hinge system has been designed to meet a technical constraint imposed by the French standard NFP 25.362, namely the function of generating no source of pinching or crushing. Thus, the hinge latch profile (V) supports semicircular wings (AI) and (A 2), whose rotation centers are successively (0 I) and (0 2), allowing profiles (Pi) and (P2) to articulate without asymmetrical sliding.

 These wings (A I) (A 2) retract into a drawer gradually penetrating, on either side, in the profiles (P 1) and (P 2), as and when the angle of rotation. Ensuring, therefore, the function anti-finger gripper, since no crushing space or pinch is formed at all angles of articulation, and this despite a panel thickness of more than 100mm, see figs 6 7. 8.

 These wings (A 1) and (A 2) fig 1, are equipped with an end pin (er.V) allowing profiles (Pl) and (P2) to abut, when the angle of the articulation exceeds 180 degrees, allow to limit the angle of rotation of this hinge principle to 180 degrees. These lugs (er.

V) are associated with the hinge stop pin (E. C) which alone would not be sufficient to block the articulation at 180 degrees, this angle to ensure the alignment of the panels of panels connected by this articulation method.

 On the other hand, these lugs have another essential function, which is to lock by snapping the hinge latch profile which has a strut (F), centered in the middle of the wings (A1) and (A2). This strut has been implanted to form a reinforcement of inertia, able to withstand the wind pressure on the panels, (Fv), fig 1, prohibiting the assembly an arrow greater than 17300 th for a width of panels up to 5 meters.

The hinge latch profile is an essential part of this hinge concept, because it allows to assemble an assembly, snap, lock, fast and without special tools, the 3 profiles constituting this principle of articulation The hinge latch (V) snap-in combination of (Cl) and (C2), with profiles (Pi) and (P2), constitute a very strong interlocking node This operation is done in three phases, as shown in the illustrations of Figures 9.10.11
The 3 elements: (P2), (V) and (Pi), constituting this joint, can be mounted between them, by simply snapping the hinge lock (V), on the profile (P2) The hinge lock (V) being already pre-latched on the profile (pu), (P1) and (P2) being already nested to each other to form an angle at i 80 degrees
This particularity is of essential technical and economic interest, because it reduces the need for tools and especially the time of assembly on the site, where generally it is necessary to provide drills and screwdrivers, to implement the screws of traditional hinges.

 In order to perfect the economic performance of the product. material saving tips have been made Thus, for the profiles (P 1) and (P 2), instead of providing in the design of the aluminum dies, for the axis of the end roller, a tubular housing which would cover the whole profile and constitute the material whose presence would be useless over 9'o 'of the length of the profile. a concept of lugs (E), see fig. 1, allows to implant a nfide thermoplastic support (S), which would be limited to the length of the axis of the end roller .figs 1. 2.

 To allow easy and fast assembly of the ends of the panels, a housing for receiving self-tapping screws. (Alv), fig 1, has been provided in the extrusion profiles (P 1) and (P 2). The entire design process of this hinge, and its association with panels (which will be articulated with each other), has been oriented in the spirit of productivity gains, which is at the very level of product manufacture.

This is the case of the assembly technique of the profiles (Pl) and (P2), thanks to the outer ends (Ex), profiles (Pl) and (P2), designed to receive various materials (M), the profiles (P 1) and (P2) are "welded" to the panels by an immediate bonding process, obtained from a double-sided adhesive This double-sided adhesive delivers all its shear and peel strength performance, if it is maintained in compression
This is why the panel is caught in a vise with the help of a biter, the assembly of which is done according to the principle of translation (T), perpendicular to the plane of the panel
This pareclose thus comes into line sealing support (Et), on the inner face of the material (M) figl This plane also being the adhesive bonding plane, it is then in compression as desired, to deliver the optimum of its qualities of adhesion.

Despite the inevitable constraint on the French market, to make sectional doors to measure, ie, with dimensions (height - width) always different and personalized, because matched to the bays of non standard French buildings; the current
Invention allows, despite everything, to consider an industrial manufacturing, which was developed in a concept of ultra-fast manual assemblies allowing the unique use of a specialized workforce, to the detriment of a robotization that would not be efficient in terms of the complexity and the cost it would generate, if it were to assume non-standard and non-repetitive mechanized manufacturing.

In summary, the present invention optimizes material costs, as well as labor costs, which allows it to claim industrial application, despite a non-standardization of dimensions, and a very varied use of filling materials for the constitution of the body of the panels. This optimization of the labor cost is concretized on the 2 main stages of the implementation of the product:
1- Optimization on the cost of fabncation panels, workshop.

 2- Optimization on the cost of mounting the panels together, on the installation site.
