Abstract

The U-shaped profile (4), in which the edge of the additional pane (3) is mounted, comprises a tongue integral with the U for the attachment of the profile on the upright (2) of the window. The tongue comprises two flexible zones (16, 17) forming hinges and separating the tongue into three rigid parts (18, 19, 20) connected by the hinges. The rigid part (18), which is closest to the U, is in the extension of a branch (11) of the U. The rigid part (20), the furthest away from the U, is intended to be attached to an upright (2) of the window. The intermediate rigid part (19) is provided with a projecting edge (24). The bottom (13) of the U is provided with a projecting edge (21) turned towards the tongue. The edge (24) and the edge (21) are shaped in such a way that when the bottom (13) of the U is folded over at 90 DEG towards the intermediate part (19) about the hinge (16), they are locked in position. The hinge (17) permits another 90 DEG rotation of the U, locked to the part (19), in order that the additional pane assumes its closed position. The edges (24, 21) have the shape of feet with rounded ends which fasten together by their ends in the locking position. A supplementary glazing frame also comprises a frame profile (5) intended for locking the frame against a casing (1). The profile (5) has a U-shaped section, the bottom (29) of which comprises a slot (30) which interacts with a third edge (32) of a casing profile (7) in the form of an angle iron. <IMAGE>

Description

The present invention relates to plastic profiles for glazing framing.

Over-glazing designates a device fixed to an existing window or door and composed of a second window mounted in a frame. This improves the thermal insulation between the faces of the window by creating an air mattress enclosed between the existing glass and that of the glazing.

The profiles used for this purpose are generally made of aluminum and are therefore relatively heavy, which is undesirable. There are already profiles made of plastic, but these profiles are generally of complicated shape and relatively unsightly. In addition, once installed, the operations to be carried out for cleaning the glass are relatively laborious, since it is necessary to unscrew certain closing parts. The state of the art can, in this field, be illustrated by the French patents 2,294,311 and 2,349,018, the American patents 4,184,297 and 3,939,620, and also, the German patent 2,614,897.

An object of the present invention is to provide glazing framing profiles having no part to screw or unscrew for closing or opening the glazing, but only interlocking by interlocking and unlocking by dislocation.

Another object of the invention consists in providing a glazing whose unlocking comprises only a simple lateral force, in particular without needing to lift it to unhook it, which would be inconvenient.

Another object of the invention consists in providing a glazing which can open widely, which facilitates the cleaning of the windows.

Another object of the invention is to provide a glazing which, in the closed position, does not reveal its fixing screws, which are thus protected from the weather, this arrangement improving the aesthetic appearance.

According to a characteristic of the invention, there is provided a plastic frame profile for glazing, the profile of which includes a U in which the edge of the survitre is embedded, a tongue integral with said U for fixing the profile on the amount of the. window, the tongue comprising two flexible zones forming hinges and breaking down the tongue into three rigid parts connected by said hinges, said rigid part, closest to the U, being in the extension of a branch of the U, in which the rigid part, the furthest from the U, is intended to be fixed to a window pillar, said intermediate rigid part is provided with a first projecting edge, the bottom of the U is provided with a second projecting edge facing the tongue, the first and second edges having shapes such that, when the bottom of the U is folded at 90 ° towards said intermediate part around said first hinge, they lock, said second hinge allowing the rotation of the U locked to said intermediate part a again by 90 ° so that the survitre takes its closed position.

According to another characteristic, the first and second edges have the shape of feet with rounded ends which hook at their ends in the locked position.

According to another characteristic, there is provided a glazing frame comprising a profile as defined above.

According to another characteristic, a frame is provided which further comprises a profile intended for locking the frame against a frame, said second profile having a U-shaped profile, the bottom of which has a notch cooperating with a third edge of a third frame profile in the form of a square.

The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:

• Fig. 1 is a sectional view of a window provided with a glazing assembly using profiles according to the invention,
• Fig. 2 is a sectional view of a profile of a first type fully unfolded,
• Fig. 3 is a sectional view of the profile of FIG. 2, folded at 90 °,
• Fig. 4 is a sectional section view of FIG. 3, folded a second time at 90 °,
• Fig. 5 is a sectional view of a profile of a second type, and
• Fig. 6 is a sectional view of a profile of a third type.

In Fig. 1, the uprights 1 and 2 of a window have been shown on which is fixed a glazing assembly according to the invention. The glazing assembly consists of a window 3 and U-shaped profiles 4 and 5, in which the window 3 is embedded. The profile 4 is fixed to the upright 3, directly by screws 6, while the profile 5 is locked by a piece 7 with an L-profile, which is fixed to the upright 1 by means of screws 8. Seals 9 and 10 are provided under the profiles 4 and 5 and are crushed, in the closed position, against the uprights 1 and 2 of the window. The sections 4, 5 and 6 are for example made of PVC.

As shown in Fig. 2, the part forming the profile 4 in the general shape of a U with two branches 11 and 12 which have, at least partially, a sawtooth profile 14 oriented towards the bottom of the U. In addition, the U can be slightly closed to ensure better pinching.

On the other side of the branch 12, the bottom 13 is extended by a tongue 15 comprising parts 16 and 17, forming hinges which break down the tongue 15 into three parts 18 to 20.

On the other side of the branches 11 and 12, substantially on the middle of the bottom 13, there is provided an edge 21 whose profile has the shape with a base base parallel to the bottom 13 and the end 22 of which is turned in the direction from 11 to 12. Between the end 22 and the bottom 13, a groove 23 is thus created. In practice, the end 22 has a profile round.

The hinge 16 is formed by a reduction in the thickness of the tongue 15, which results, for example, in a V-shaped groove open towards 21.

On the part 19 of the tongue, an edge 24 is provided, the profile of which is the same or substantially the same as that of the edge 21, with a tip 25 facing the bottom 13 and a groove 26 between the tip 25 and the part 19. The width of the grooves 23 and 26 is slightly greater than that of the rounded ends 22 and 25. The distance from the center of the hinge 16 to the external face of the bottom 13 is slightly greater than the height of the edge 21. The distance from the end 25 to the center of the hinge 16 is a little less than the distance from the end 22 to the part 18.

As shown in Fig. 3, when the U 11-12-13 is rotated 90 ° relative to the center of the hinge 16, the end 25 of the edge 24 fits under the end 22 of the edge 21, in the groove 23, the end 22 being placed in the groove 26. The rounded external shapes of the ends 22 and 25 facilitate nesting. It is obvious that the section 4 thus folded, is locked in this position and can only be unfolded using tools such as screwdrivers, etc. In practice, the edges 21 and 24 fit together like a clip. In addition, the edges are thick enough that their bases avoid rotation beyond about 90 °.

The hinge 17 is produced by providing in the area considered a flexible material instead of a rigid material. The part 20 of the tongue 15 beyond the hinge 17 is pierced with holes 27 for the passage of the screws 6.

As shown in Fig. 5, the U of the profile 5 consists of two branches 27 and 28 joined by a bottom 29. The internal surfaces of the branches 27 and 28 also have, at least partially, sawtooth profiles. The bottom 29 has, on the outside, a groove 30 in the shape of a U much less wide than the main U. In practice, the section 5 is almost identical to the section 4, with the exception of the parts 19 and 20 which do not exist.

As shown in Fig. 6, the L-shaped section 6 comprises a branch 31 comprising a projecting part 32, with a V-shaped profile with rounded tip intended to fit in the groove 30 in the bottom 29 of the section 5, and a branch 33 in which are drilled ds holes 34 for the passage of the screws 8. The length of the branch 31 is sufficient for the installed glazing to extend beyond the profile 5.

As shown in Fig. 1, the profile 6, on the one hand, and the part 20 of the tongue 15, on the other hand, serve as frames for the leaf formed by the window 3 and its two uprights 4 and 5. The leaf thus formed can rotate around of the hinge 17. In the closed position, the projecting part 32 of 31 gets stuck in the groove 30.

The seals 9 and 10 are shown in the working position in FIG. 1 and in the rest position in FIGS. 2, 3, 4 and 5. These are tubes which are conventionally fixed to the profiles using glue or another suitable adhesive material. The flanges 9 and 10 are either made of flexible and deformable material, or hollow to ensure good sealing.

It will be noted that the dimensions of the sections 4 and 5 are such that in the closed position, there remains a free space between the branch 33 and the section 5, as well as between the part 20 and the branch 11.

Of course, the framing of the glazing is supplemented by an upper horizontal profile and a lower horizontal profile, which are of the type of the profile 5. The assembly of these profiles is done with a miter cut. The glass is fixed in the PVC profiles using appropriate adhesives or by hot coating of the profiles with polysulphides used for the manufacture of insulating glazing.

The installation of the glazing on the window is carried out as follows. The assembly is presented, the profile 4 being unfolded, as in FIG. 2, along the upright 2, the tongue 15 is fixed to 2 by means of the screws 6, the profile is folded twice 90 °, as shown in FIG. 4, the part 6 is then adjusted, which is fixed to the upright 3 by means of screws 8. The profile 6 can occupy the entire height of the upright or be provided in two sections which are fixed at the top and bottom.

The shape of the profiles is such that in the closed position, it is say most of the time, the means of attachment to the uprights and crosspieces are hidden by the profiles themselves. There is a generally uniform appearance with, on the four sides, an almost identical profile dimension.
