Description

The present invention relates to the field of the building, more particularly building equipment at the level of bays, passages and other openings to be closed, permanently or with possibility of opening.

The invention relates more particularly to the fixing and assembling of parecloses for holding and securing a plate-shaped element or panel in a frame forming part or constituting the body of a closure element, and has for object a device for fixing and assembling such parecloses at such a frame.

When installing plate or panel-shaped elements (in particular double-glazed panels) in a frame, generally formed by the assembly of extruded profile elements, it is appropriate to maintain this element laterally in the inner edge or rabbet of the frame, but also to wedge it in position in said frame, between its peripheral edges and the latter. In addition, for aesthetic reasons and finishing, it is of course necessary to cover the interface area between the plate-shaped element or panel and the frame receiving it. Finally, it is also necessary to ensure a seal at the interface area, and a thermal insulation and possibly sound.

These various functions are realized by the implementation of structural elements, generally profiled, called parecloses or parcloses and cooperating in pairs of opposed elements mounted on either side of the interface area while bearing on the frame and on the plate or panel-shaped element.

When the parecloses do not fill, or only partially, the wedging function, separate wedging elements can be provided, which are inserted into the peripheral interstices between the element and the frame.

A constant concern of manufacturers and customers is the security and burglary resistance provided by bay closures or similar openings, especially when they open to the outside.

Thus, it was recognized early on the need to ensure a rigid and resistant connection at the peripheral interface zone between the frame and the element mounted in the latter.

However, it is also necessary to be able to replace the plate-shaped element or panel in case of damage.

Given the needs and requirements mentioned above, the principle of fixing and assembly generally retained by the manufacturers is to connect the beadings by means of one or more screws forcing them to one another, parecloses thus pinching the frame and the element forming a rigid assembly.

Generally, these screws are placed at the level of the inner burr and extend into the outer bead. WO 99/19153 illustrates this solution.

A major disadvantage of this solution lies in the fact that it is necessary to cover each opening of introduction of a screw by a cap or cap, the establishment of which must be very precise so that it fits perfectly in the appearance and the external form of the inner burr. This installation is a delicate and tedious operation if an optimal aesthetic result is sought and provided that caps exactly adapted in terms of shape and hue are available.

In addition, in case of replacement of the plate-shaped element or panel, it is necessary to remove the caps to access the screws, where most often a deterioration of the latter or at least the aesthetic appearance changes after refitting.

In an attempt to overcome these disadvantages, it has been proposed to mount the two parecloses by assembling them by elastic engagement or notching. However, these solutions themselves have other disadvantages, since they provide either an assembly too loose and / or insufficiently resistant, which is not precisely adjustable and does not allow to catch any manufacturing tolerances. or an assembly of immovable nature and which will necessarily be damaged or completely destroyed, in case of replacement of the plate-shaped element or panel.

The present invention aims to overcome the aforementioned drawbacks, while meeting the needs and requirements mentioned above.

Thanks to the provision of a separate wedging and fixing part 5, the functions [fixing by screw of the external pareclose 3 / setting of the element 2 in the frame 1] are thus decoupled from the functions [ aesthetic overlap interior side / internal side seal], while allowing a replacement of the element 2 without damage to the assembly (removal by disengagement or unclipping of the interior bead element 4 provides access to the screw or screws fixing or bonding 11).

According to a first characteristic of the invention, the outer bead element 3 comprises at least one anchoring site 13 for receiving at least a portion of the threaded portion of said at least one fastening screw 11, and inner cladding element 4 comprises a means 14 for engaging the removable mounting site 12 of the masked wedging and fixing part 5.

The provision of a specifically adapted anchoring site 13 makes it possible to ensure a stronger connection and avoids any damage to the outer bumper 3 itself, especially in the case of repetition of the screwing / unscrewing operations.

Advantageously, the anchoring site 13 is formed by or housed in a protruding extension 13 'inside or on the non-visible face of the outer bead element 3 forming a nose or portion of a tube and also constituting a piece of additional wedging having, if appropriate, a thickness at least slightly decreasing towards its free end directed towards the inner baffle element 4 in the assembled state (Figures 1 to 5).

In order to be able to provide a possibility of catching manufacturing tolerances of the frames 1 and the elements 2, the two planar spaced bearing surfaces 7 and 7 'of the wedging and fixing part 5 are slightly divergent from each other. other, having at greater spacing at their free ends ending in the attachment flanges 8 and 8 ', at least one 6 of the longitudinal walls 6, 6' defining the bearing surfaces 7 and 7 ' , preferentially the one 6 bearing on the profile of the frame 1, is elastically deformable, at least over a portion of its adjoining width by means of attachment 8 corresponding.

According to a first variant of a first embodiment of the invention, shown in Figure 1, the engagement means 14 consists of a notch or hook formed on a flange 15 of a profiled element 15 'attached to the non-apparent face of the inner bead element 4, for example by screwing.

According to a second variant of the first embodiment of the invention, shown in FIG. 2, the engagement means 14 consists of a notch or hook of a wing 15 formed on the non-visible face of the element 4 of FIG. internal partition 4.

In the context of the two aforementioned variants, and as shown also in FIGS. 1 and 2 of the accompanying drawings, the site 12 for the removable mounting of the wedging and fixing part 5 may consist of a notch or hook formed on a second wing 16 extending substantially coplanar longitudinal profiled wall 6 'bearing on the edge 2' of the element 2 in the form of a plate or panel, the inner clipping element 4 in close support, in the mutually engaged state two notches or hooks 12 and 14, on the one hand, on the inner face of the frame 1 by a first longitudinal edge 4 ', being wedged against the fastening flange 8 engaging on said frame 1, and, on the other hand, on the inner face of the element 2 in the form of a plate or panel by a second longitudinal edge 4 ", preferably provided with a seal 4"'.

According to a second embodiment of the invention, and as shown in Figure 3 of the accompanying drawings, the engagement means 14 consists of a notch or hook formed on the non-visible face of the inner bead element 4, near the longitudinal edge 4 "bearing on the element 2 in the form of a plate or panel, preferably via a seal 4" '. Then, the site 12 of the removable mounting part 5 of wedging and fixing may consist of a notch or hook formed as an extension of the fastening flange 8 'engaging the element 2 plate-shaped or panel, the inner bead element 4 coming into intimate support, in the mutually engaged state of the two notches or hooks 12 and 14, on the one hand, on the inner face of the frame 1 by its other longitudinal edge 4 ' , being wedged against the fastening flange 8 engaging on said frame 1, and, secondly, on the inner face of the element 2 in the form of plate or panel.

According to a third embodiment, shown in Figures 4 to 8 of the accompanying drawings, the engagement means 14 consists of a domed head of a stud 17 formed or reported at the non-visible face of the element of 4, and the site 12 of removable assembly is formed by two spaced apart wings 18 and 18 ', elastically deformable and terminated by opposite hooks or notches 18', intended to come into pinch engagement on the rear of said head 14 after passage of the latter between the two notches or hooks by deformation under stress of said wings 18 and 18 '.

Preferably, and in order to be able to use an identical pareclose profile for the internal and external 4 bead elements 3, each pad 17 with domed head 14 (at least radially) can be formed by an extension 19 identical to the protruding inner projections 15 ' of the outer bead element 3 comprising the anchoring sites 15, into which is screwed to a given depth, a screw 19 'with a domed head 14 in drop-of-tallow or the like.

It will be noted, for all the above-mentioned variants, that the walls 6 and 6 ', as well as the wings 8 and 8', may each have either a profiled unitary structure (integral structure, without discontinuity), or a fractional structure in several discontinuous profiled segments aligned with each other (FIGS. 7, 8 and 10), the functions performed by these two variants practical embodiments being identical and understood the scope of the invention.

Similarly, in the embodiments shown in Figures 1 to 3, the notches or hooks forming the site 12 and the means 14 may also have a continuous structure (unit profiled) or fractional.

In order to ensure an intimate application of the inner bead element 3 on the inner faces (located on the inner side) of the frame 1 and the element 2, it can be provided that the cooperation of the or each engagement means 14 with the or a corresponding removable mounting site 12, in the mounted state of the inner bead element 4, permanently urges the latter against the element 2 in the form of a plate or panel and against the frame 1.

This permanent stress can result from the elasticity of the wings carrying the notches or hooks, or by the engagement of the latter at a slope or a narrowing generating a pushing or pulling force of the bending element. interior 4 to the frame 1 and the element 2.

As shown in FIG. 4, and in order to facilitate the peeling or lifting of the inner bead element 4 from the frame 1 with a view to its removal, it can be provided that at least one tongue, rib or tab 20 of small thickness and small width, reported or formed integrally, is located between the longitudinal edge 4 'of the inner bead element 4 resting against the frame 1 and the latter.

Removal of the inner bead element 4 can easily be effected by lifting the edge 4 'over the flange 8, thereby disengaging the notches or hooks (FIGS. plot (Figs 4 to 6).

The mounting of the element 2 in the form of plate or panel in the frame 1 (formed of profiled elements or not) requires a mutual assembly and joining of the latter on the different lateral sides of said element 2 by the implementation corresponding devices, unitary structure for the side considered or fractional structure.
