Description

The invention relates to a jamb, and a shutter box rolling stock, of which at least one of the longitudinal walls consists of such jamb.

More generally, it can be used to constituting all or part of a structural element presenting a zone hidden in a frame and another visible, such as, for example, a beam.

Currently, in the building sector, to protect planned openings in the construction, we use in particular various blinds, grilles or shutters.

For this purpose, it is known rolling shutter boxes presenting side walls between which a reservation is defined to accommodate the blind. These side walls constitute jambs by the end of which the chest is in contact at least partially with the walls of the construction defining the opening, intended to be closed by the shutter rolling.

In order to reinforce the jambs, they are equipped at edge in contact with the construction of a metal reinforcement profile.

A disadvantage of such reinforcing profiles is that it is necessary to paint them to improve their appearance in the area or areas where they are visible.

To date, it is also known to use these profiles of reinforcement to stop the coating covering the jamb externally. For that, said reinforcing profiles are extended at the bottom to define a support surface for the coating.

Nevertheless, at the level of the lateral edges of the opening, the coating must not be stopped and said extensions of such profiles constitute a gene. They must be deleted which complicates the installation of the safe. If they are left behind, they provoke cracks in the plaster.

Document DE-A-40 13 000 is known from a jamb of rolling shutter box whose body has at least one of its longitudinal edges a trim 5. This trim consists of two separate profiles, one of reinforcement, and the other of dressing. The reinforcement profile covers said body over at least a part of its length, and said profile covering covers said reinforcing profile at least in one or more zones of the latter destined to be seen. In addition, said reinforcing profile has means for stopping a jamb covering coating.

Such a structure has the same disadvantages as those mentioned above, at the side edges of the opening, because the means of stopping the reinforcing profile constitute a gene and must must be removed in order to avoid causing cracks the coating.

The purpose of the present invention is to propose a jamb provided with a trim that overcomes the aforementioned disadvantages and allows a setting in place facilitated the structural element which said leg constitutes a party, in particular by avoiding having to paint it.

Another object of the present invention is to propose a jamb equipped with a pad that allows to stop the coating intended for the cover while limiting the risk of cracks.

Another object of the present invention is to propose a jamb equipped with a pad that allows a better holding of the coating intended to cover it.

Another object of the present invention is to propose a jamb equipped with a pad that avoids stagnation of the runoff likely to intervene at said jamb.

Other objects and advantages of the invention will appear at course of the following description which is indicative only and which is not intended to limit it.

The invention relates first of all to a leg, in particular chest, consisting of a body presenting at least one of its songs a lining, said lining consisting of a profile of reinforcement and a trim section, distinct, said reinforcing profile covering said body over at least part of the length of said body, and said profile covering covering said reinforcing profile at least in one or more zones of the latter intended to be seen, the said pad further having means for stopping a jamb covering coating, characterized in that that said reinforcement profile has two hooking wings to one of said body songs, connected by a wing of protection of said song, and by the fact that said means for stopping the coating are provided at the level of the profile covering, thus forming part of said profile.

The invention also relates to a roller shutter box having at least two longitudinal walls between which a reservation, able to accommodate said rolling stock, is provided, at least one said longitudinal walls being constituted by a jamb as described more high.

• Figure 5 is an alternative embodiment of the element shown in Figure 4 above.

The invention relates to a jamb. By "jamb", we means any part of a structural element such as, in particular, a trunk, beam or other, or any structural element intended to be embedded in a construction 50, over part of its length, to support, on its own or not, at least said structure, the other part of the leg being intended for stay visible, at least partially.

As illustrated in FIG. 1, the jamb 1 conforms to the invention consists of a body 2, possibly one-piece with the structural element 3 whose jamb 1 may be part. Said jamb 1 present at the level of at least one of its longitudinal songs 4 a trim 5, in particular to increase the strength properties to the constraints of the jamb 1 to avoid its deterioration.

According to the invention, said lining 5 consists of a profile reinforcement 6 and a covering profile 7, distinct, said reinforcing profile 6 covering said body 2 over at least part of its length and said profile covering 7 covering said reinforcing profile 6 at least in the one or more areas of the latter to be seen. "Profile" means element extending longitudinally.

With such a solution, implementation is simplified and made more easily modular.

As illustrated in FIG. 2, said reinforcing profile 6 is subject, for example, to said body 2 and said trim section 7 is subject, for example, to said reinforcing profile 6. For this, said reinforcing profiles and 6, 7 have, in particular, hooking means 8, 9.

Said packing 5 comprises, for example, means stopping 10 of a coating 11 of the cover of the jamb 1, means fastening 12 of said coating 11, receiving means 13 of elements 14 and / or means 15 for directing the flows involved at the jamb level 1.

The coating is eventually stopped on only one part the length of the jamb 1, more precisely at the level of the zone or zones intended to be accessible to the eye.

According to the invention, provides said means 10 for stopping the coating at said dressing profile 7. With such a solution, the necessary length is directly available and sufficient without having to perform notching not to be embarrassed by the presence of plaster stop means in places where they would be useless, even harmful.

That being so, said means 15 for directing the flows are also provided, possibly, at the level of said trim section 7. As for said attachment means 12 of the coating and / or said means 13 of an external element, they are provided, in particular, at the level of said reinforcing section 6.

As illustrated in FIGS. 3 and 4, said stop means 10 of the coating are constituted, for example, by a lateral extension 16, in particular in the mass, of said covering profile 7, provided covering said reinforcement section 6 on one of its faces 17.

Said extension 16 has, for example, a groove 18, distant from its free edge 19, able to allow or to participate in a fastening said covering profile 7 to said reinforcing profile 6 by cooperation with one or more projections 20 provided on said profile of reinforcement 6. Said attachment is also reinforced by the lever effect formed by the coating 11 on the trim profile 7 around the said one or more growths 20.

Said reinforcing section 6 is provided, in particular, all along said body 2 of the leg, said groove 18 being provided defined all along said casing profile 7, in the mass, and unedite outgrowth 20 of said cladding profile 7 being provided all along said reinforcing profile 6, in the mass. There is thus a means 10 for stopping coating directly constituted by said trim section, which simplifies the both manufacturing and laying.

The length of the covering profile 7 is, in particular, less than the length of the reinforcement profile 6. By way of example, said jamb 1 may be provided opposite an opening 41 provided in the construction 50, of length " l _o ", as shown in Figure 1. Said jamb 1 is then of length" I "greater than the length" l _o "to allow its support on the edges of said opening, and it is provided with a reinforcing profile 6 of length "I" and a trim profile 7 of length "l _o ". The width of the covering profile 7 is, in particular, at least equal to or greater than that of the reinforcing profile 6, at its face 17.

It is therefore found that it is sufficient to have reinforcing profiles 6 and trim 7, cut by the meter, which is cut to the desired length "I" or "I _o ", without having to then perform resets.

As illustrated in FIG. 5, said extension 16 has, optionally, dimensions adapted to the thickness of coating 11 desired. Such a characteristic makes it possible not to have to modify the stop means 10 of the coating at the time of installation.

Said fastening means 12 of the coating consist of for example, ribs 21 provided on one of the faces 22 of the profile of reinforcement 6.

Said ribs 21 are provided, in particular, inclined by referred to said face 22 and arranged head to tail so as to define grooves 23 dovetail for the attachment of the coating 11. Said ribs 21 are made, for example, in the mass.

Said means 13 for receiving an external element are consisting of, in particular, a housing 30 defined in the walls of said profile of reinforcement 6.

Said means 15 for directing the flows are consisting, for example, of a protrusion 24, defining a "drop "pendant" provided at one of the longitudinal edges 25 of said profile 7. It concerns, in particular, the longitudinal edge opposite to that presenting the extension 16.

Said protrusion 24 is constituted, for example, by a excess thickness of said trim section 7, provided in the mass.

If we refer more precisely to Figures 3 and 4, we notes that said reinforcing profile 6 has, in particular, a profile substantially U-shaped consisting of two attachment wings 26, substantially parallel, connected by a protection wing 27, substantially orthogonal to the two previous ones. Said attachment wings 26 may carry claws 28 for holding said reinforcing section 6 on said body 2.

One of the attachment wings 26, in particular the inner wing, further has a recess 29 to define with the wing protection 27, said housing 30 for receiving external element. In order to facilitate the reception of it, a chamfer 32 may be provided at one of the edges 31 defining the opening of said housing 30.

The latter is planned, possibly, on a part only the width of said reinforcement profile 6. A hooking groove 34 of said covering profile 7 can therefore be provided at this level.

In this regard, the protruding protrusion 20 of the profile 7 is located, for example, along an edge of said profile of reinforcement 6, in particular outer, the fastening ribs 21 of the coating being provided at the level of the corresponding fastening wing 26.

Said protective wing 27 is intended to be in contact, in particular, on the one hand, with said covering profile 7 and, on the other hand, with the built in contact with which the jamb 1 can be.

Said reinforcing profile 6 is constituted, for example, in a metal material, while the trim profile 7 is made, in particular, in a plastic material, for example, colored.

Said covering profile 7 is formed, in particular of a wing of width greater than that of the protection wing 27, by the presence of said lateral extension 16.

Said wing forming said trim profile 7 has, in in addition, possibly, hooks 35, 36 for hooking onto said protrusion 20 and / or in said groove 34 of the reinforcement section 6.

After installation, said protective wing 27 and said wing forming the covering profile 7 are intended to be substantially parallel one to the other.

As previously mentioned, all protrusions 20, gripping ribs 21, claws 28, recess 29, and grooves 34 are made in the mass of said reinforcing profile 6. Similarly, the set of lateral extensions 16, protuberances 24 and / or hooks 35, 36 are made in the mass of said covering profile 7.

Referring again to Figures 1 and 2, it should be noted that the invention also relates to a rolling shutter box having at least two longitudinal walls 37, 38 between which a reservation 39, suitable for receive said shutter 40, is defined, at least one of said 37 walls longitudinal, especially external, consisting of a jamb 1 such as described above.

Said shutter box constituting said element of structure 3, previously mentioned, is provided, for example over a opening 41 formed in the construction 50 on which it rests by the recessed longitudinal end of its lateral sides 37, 38.

Said trunk has, in particular, a monobloc profile U optionally closed by a board 42 provided with a slot 43 for the passage of the deck of said shutter. Said board 42 is provided suitable, possibly to be accommodated in said housing 30 of the lining 5.

Said trunk is constituted, especially at its walls 37, 38, for example, at least one reinforced expanded material by a wire mesh, veneered with fibreboard which, by example, completely fill said reinforcing profile 6, to favor hanging.

Naturally, other modes of implementation, within reach of the person skilled in the art, could have been envisaged without departing from framework of the invention.
