Description

. I k * 4 1 Gasket.

The present invention relates to a seal of a particular type suitable in particular for ensuring the sealing of pivoting or fixed windows 5 mounted in walls of any type of construction, more particularly caravans, mobile homes of all kinds and mobile offices.

Various types of seals intended for this purpose are known which are made of rubber. Such a seal 10 generally comprises a part generally affecting your shape of a U-shaped profile which fits on the edges of the bay, and a tab integral with this profile, which is folded against the latter by the window When the latter is closed. However, the rubber, for reasons of stability, is loaded with carbon black which does not allow variations in color and which therefore cannot be adapted to the color or tint of the wall. Furthermore, the rubber takes on a dirty and brittle appearance after a period of use and exposure to the weather.

Furthermore, a PVC joint, possibly colored in your mass and of a color suitable for the partition, is not suitable in the case of windows made of acrylic material, since this may have cracks or other alterations due to contact with 2 k, - «« 1 PVC.

- Other synthetic materials having elastomeric properties are expensive and can therefore only be used with great difficulty for the manufacture of a joint of the above-mentioned type consisting of a homogeneous material.

An object of the present invention is to provide a special seal "intended to be mounted on the edges of the opening made in a wall and ensuring sealing.

/

Another object of the present invention is to provide a seal of the above-mentioned type which does not have the drawbacks of known rubber seals and which presents an acceptable cost.

15 The objects of the present invention are achieved by a seal suitable for sealing the pivoting or fixed windows mounted in walls of qonstructions, characterized in that it consists of at least a first part affecting 20 overall the shape of a U-shaped profile and nestable on the edges of the opening, said first part being constituted by an inexpensive synthetic material, wholly or partly colored in the mass, such as PVC, and a second part coming into contact with the window, said second part being integral with> · 3 1 the first and constituted by a synthetic material different from the first but compatible with the constituent material of your window.

According to one embodiment, said second part 5 can be made integral with the first by gluing, or any other means known per se. However, preferably, said second part is secured to the first by coextrusion of the composite seal.

A synthetic material which is well suited for said second part is polyurethane, polyethylene and polypropylene.

It is noted that a seal according to the present invention can be colored in the mass in a monochrome or multicolored manner and present a pleasant appearance adapted to the wall of the caravan for example, while ensuring a seal as good as rubber. . It is also found that the difficulties of compatibility between the material of the window and that of the seal have been overcome while providing an inexpensive seal which does not have the disadvantages of rubber seals of the state of the technical.

According to a first variant in accordance with the present invention, said second part consists of a • 4 4 ί!

Tongue extending from the first part and arranged on an amount of the profit from the first part. This embodiment is more particularly suitable in the case of pivoting windows, the said tab being folded down so as to be applied under pressure against the window in the closed position.

Advantageously, the first part comprises, preferably in the base of the profile corresponding to the thickness of the wall in which the opening is made, the recess intended for the fixing means such as staples, screws or the like, a tongue! articulated by a line of low resistance along an edge of said recess being provided to cover said recess. This articulated tongue can be kept in the closed position by a tight fitting or by snap-fastening.

According to another variant in accordance with the present invention, said second part also generally has the shape of a U embedded in the base of the profile constituting said first part and has a recess whose walls tightly fit the glass surface. of the window which is introduced there. Advantageously, an upright of the U forming said second part is free in deformation and is locked, when the glass surface is mounted, by an articulated tongue along a line of low resistance of said first part, said articulated tongue being advantageously held in the closed position by a tight fitting or by snap-fastening.

This embodiment is more particularly suitable in the case of a fixed window., That is to say a window which is not intended to be opened.

Advantageously, the seal according to this latter embodiment also comprises a groove or groove for the collection and evacuation of condensation water and the like.

It is found that a seal according to the present invention can be easily manufactured by coextrusion for example. Other manufacturing methods such as bonding can also be envisaged. In addition, such a seal can be made of an inexpensive material, such as PVC, while being colored or not in the mass and adapted to the color of the wall of the construction. The arrangement in two parts of different materials prevents degradation of the transparent surface due to incompatible materials.

The invention is described in more detail below, with the support of the figures in which: - Figure 1 is a cross-sectional view through a joint according to the present invention; - Figure 2 is a view cross section at t 6 through a joint according to the invention, according to another embodiment.

Referring to Figure 1, a seal 1 according to the invention is mounted in a window opening 5 formed in a wall 3 shown succinctly.

The seal 1 is composed of a first part 5 in the form of a U-shaped profile fitted onto the wall 3 and of a second part 7 in the form of a tongue secured to 10 The first part in the extension of the base of the profile 5. The Tab 7 deviates from Part 1 / Part 5, becoming thinner. When the window is closed, the tab 7 is folded down and pressed in a sealed manner against the said window.

15 The tongue 7 and the profile 5 are made of different materials, the tongue 7 having elastomeric properties and preventing contact between

Said first part 5 and The window (not shown).

'*.

Advantageously, the base of the profile of the first part 5 comprises a recess 9 intended for the arrangement of the fixing means (not shown), such as staples, screws or the like. A tongue 11 articulated on a weak line Resistance 13 can be folded down to cover said fixing means and hide the recess 9. It can be kept in closed position (continuous cuts) by an interlocking of the type known per se or by snap-fastening of a nose 15 disposed in the extension of said tongue 11 and engaging in a corresponding notch 17.

5 It is obvious that the width of the joint is chosen as a function of the thickness of the wall 3.

In order to avoid any infiltration of water by capillarity into the wall, a bead of mastic may also be provided between the wall and the uprights of the profile 5.

/ fl Figure 2, there is shown another embodiment of a seal according to the invention. In this case, the second part 7 is also in the form of a U-profile inserted in said first part, that is to say in the base thereof. The recess 21 is arranged in such a way that said second part 7 adapts in a sealed manner to the transparent surface which will be introduced therein (not shown). According to a preferred embodiment, an upright 7 ′ of the second part can be freely deformed without its movements being hampered by the material constituting said first part 5. Once the glass surface has been introduced at 21, a tongue 23 25 articulated on a line of weak resistance 25 from »\ 1 a * said first part can be tilted to block Said upright 7 '. The tongue 23 is advantageously held in position in a manner analogous to the previous embodiment, for example by a nose 27 5 engaged in a notch 29.

Advantageously, the seal according to the invention also has a groove or groove 31 for harvesting and evacuating condensation water for example, which can form on the surface of the fixed window. The seal according to the present invention has the advantage of greater rigidity compared to flexible rubber seals. The tongues 11 and 23 can therefore be an integral part of the rest of the joint which is therefore produced in one piece whereas for conventional joints it was necessary to have recourse to a separate relatively rigid tongue to mask the fixing means. seal in the bay.

It is obvious that the present invention is not limited to the embodiments described but that it extends to the scope defined by the claims.
