FR2844825A1 - WINDOW OR WINDOW CARRIER, SLIDING WITH LOCKABLE LEAVES WITH SEALED SUPPORT ON THE FRAME - Google Patents

Abstract

The sliding window comprises two leaves (2,3) provided with rollers (11) which run on a fixed rail (7) enabling the leaves to move in an orthogonal direction (D2,D3) to the rail longitudinal axis (X7,X'7). The leaves have watertight support joints (140,150) on stops (8,9) connected to the window frame (50) or to another leaf.

Description

The present invention relates to a window or a French window, and more

  particularly of the sliding type. Such a window or French window generally comprises two parallel vertical leaves sliding relative to one another, in generally horizontal directions by means of rails. These rails are located in the upper and lower part of the window frame, or of the French window, and provide support and guidance for the leaves. The rolling of the leaf on the rail with a minimum of friction is generally ensured by rollers. In order to allow the leaf to roll on the rail while ensuring the protection of the rollers against external contamination, the lower part and the upper part 15 of each leaf are provided, over their entire length, with brush seals situated generally on both sides. other pebble. If this type of brush seal protects the rollers while allowing the leaf to slide on the rail, this protection is not waterproof. This lack of tightness 20 implies that the soundproofing, thermal and against drafts of this type of window, or French window, is lower than with a window or French window with

  "French-style" opening.

  It is to this drawback that the invention more particularly intends to remedy by proposing a sliding window or French window with high sound and thermal insulation against drafts. To this end, the subject of the invention is a window or French window comprising at least one leaf, provided with rolling means on a fixed rail carried by a frame, characterized in that the rolling means are adapted to allow a displacement of the leaf in a direction generally orthogonal to the longitudinal axis of the rail and in that the leaf is provided with at least one sealed support means against abutment means, connected to the frame or to another leaf, at the end of a displacement of

leaf according to said direction.

  Thanks to the invention, a seal is provided between the outside and the inside of a room, when the leaves are in the closed position. The sound and thermal insulation against drafts of such windows is greatly improved while preserving the free movement of the 10 leaves on their respective rails thanks to the displacement

orthogonal to the rails.

  According to advantageous but not compulsory aspects of the invention, the window or the French window incorporates one or more of the following characteristics - the support means comprise at least one seal

  able to come into abutment against the means forming a stop.

  Advantageously, the seals are made of synthetic material,

preferably an elastomer.

  - The means forming a stop comprise a support 20 for the rail.

  - The means forming a stop include an elongated part carried by, or in one piece with the frame located between two leaves and the largest direction of which is generally parallel to the main planes of the leaves. Advantageously, this part is hollow and forms an insulating chamber between two parts of the supporting frame

  each a leaf. Alternatively, the room is full.

  - The means forming a stop are carried by or

  monoblocks with a profile of another leaf.

  - The support means of the same leaf simultaneously exert on the means forming a stop support in the same direction generally orthogonal to the plane

main leaf.

  - The rolling means are oscillating rollers, alternatively they are pendular rollers or

sliding on their axis.

  The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a window conforming to its principle, given solely by way of example and made with reference to the accompanying drawings in

  which: - Figure 1 is an overview of a

  window with two sliding leaves.

  - Figure 2 is a partial view of the two leaves and the frame along the section plane II in Figure 1. - Figures 3A, 3B and 3C are schematic representations of the possible movements of

  leaves in the case of a window with two leaves.

  The window 1 shown in FIG. 1 comprises two vertical and parallel leaves 2 and 3 each formed by a generally rectangular frame. These frames, generally made of metal, such as steel, aluminum, wood or PVC, consist of profiles 40 horizontal and 41 vertical. A main plane P2, respectively P3, which is the plane of symmetry of the glazing of the leaf in question, is defined for each leaf 2 or 3. The window comprises on its periphery a frame 5 formed of horizontal sections 50 of length L and vertical 51 of height H. As shown in FIG. 2, the frame 5, horizontal in the lower part, includes, across its width, a horizontal base 30 6 supporting, at each end, a rail 7. This is in the form of an elongated U-shaped piece. The maintenance of the rail 7 is provided by an elongated tubular element 8 of generally parallelepipedal cross section provided on the one of its faces, of a

  longitudinal recess in which the rail is embedded.

  The element 8 and the rail 7 are thus arranged in a direction generally parallel to the length L of the frame 5. The base 6 also has a longitudinal recess

  E accommodating a room 9. This room 9, elongated, closed and hollow, is generally of parallelepiped shape and is thus arranged with its greatest direction generally parallel to the longitudinal axes X? and X'7 of the 10 rails 7.

  In FIG. 2, the part 9 is located approximately on the basis of the base 6 of the frame 5. The latter is thus provided, in the mirror position relative to the central part 9, with two rails 7 and two similar rail supports 8 15 . A leaf, 2 or 3, has at its lower end and over the entire length of the profile 40, a longitudinal opening 10 of sufficient width to receive a rail 7 fixed on the support 8. The leaf 2 or 3 moves on the rail 7 by means of rollers there located in the opening 20 10. The latter are free to rotate about a horizontal axis 12 on which they are mounted so as to be able to oscillate from an angle a around the vertical, while being maintained vertically in the central position in the opening 10. At the end 13 of the opening 10, the latter 25 is provided with supports, in relief 14 equipped with a groove. These supports 14 are oriented towards the inside of the opening 10 and extend over the entire length of the leaf 2 or 3, in a generally horizontal plane. They occupy the spaces situated respectively between the internal faces 2A, 2B or 3A, 3B of the leaf 2 or 3, and the external faces 8A, 8B of the rail support 8. A horizontal external relief 15 situated on the external face 2C or 3C leaf 2 or 3, and similar in shape to the reliefs 14, occupies the space between the face 2C or 3C of the leaf 2 or 3 and the face 9A or 9B of the part 9 by presenting its groove

facing the latter.

  Each relief 14 occupying the space between the faces 2A or 3A and 8A, supports a neoprene seal 140, the relief 14 occupying the space between the faces 2B or 3B and 8B supports, for its part, a brush seal 141. Each relief

  also supports a neoprene seal 150.

  In the open position of the leaf 2 as shown in Figure 2, the roller 11 has an inclination oriented 10 towards the outside of the frame 5 at an angle a. This inclination, caused by a displacement of the leaf represented by the arrow F1 and effected in a direction D2 generally orthogonal to the longitudinal axis X'7 of the rail 7, by means of gripping means of the leaf 15 not shown, makes it possible to separate the latter of element 9 or the other leaf. The leaf 2 is then moved perpendicular to its main plane P2. In this position, the seals 140, 150 carried by the elements 14 and 15 are spaced respectively from the face 8A and from the face 20A by a value ranging generally from 2 to 5 millimeters. The brush seal 141 is in contact with the face 8B. In this configuration there is no friction due to the seals 140 and 150 between the leaf 2 and the support 8. It is therefore easy to maneuver the leaf, against the friction forces due to the brush seal 141, for the move on rail 7 to close or open the window. As shown in FIG. 2 with the leaf 3, 30 when the roller 11 is brought back to the vertical position, the seals 140 and 150 carried by the reliefs 14 and 15 are pressed on the faces 8A and 9B respectively. The part 9 and the face 8A then form a stop for the movement of the leaf in the direction of an arrow F2 directed towards the other leaf and G made in a direction D3 generally orthogonal to the axis X7 of the rail 7. The leaf 3 is moved

  perpendicular to its main plane P3.

  According to an aspect of the invention which is not shown, a part of structure and function similar to part 9 is carried by or in one piece with the vertical sections 51.

  According to another not shown aspect of the invention,

  a vertical profile 41 of a leaf 2 or 3 comprises means forming an abutment for support means equipping a profile 41 of the other leaf 3 or 2.

  Locking means, not shown and located on each leaf, make it possible to keep the latter blocked with its seals 140 and 150 in abutment respectively against the face 8A and the face 9B or, more generally, against the frame and the other leaf. The crushing of the neoprene seals 140, 150 in this configuration ensures the seal between the outside of the leaf and a first zone Z1 situated between the element 8 and the part 9. There is also the seal between the outside and a second 20 zone Z2 formed by the part of the opening 10 housing the

rollers 11.

  The part 9 being hollow, the air which it contains participates in the sound and thermal insulation of the window frame. The part 9 behaves like a third zone 25 of insulation Z3. This insulation zone, unlike the previous two, is permanent regardless of the position of the leaves 2 or 3. We thus find significant thermal and sound insulation. Such a system makes it possible, as shown in FIGS. 3A, 3B and 3C, to have the two leaves in the closed position (FIG. 3A), in the open position (FIG. 3B) or one open and the other

closed (Figure 3C).

  Such a window can have more than two leaves,

  in practice up to eight or more.

  In another embodiment, the brush seal 141 can be replaced by a slide or another type of seal. As a variant, it is possible to use brush seals in place of the elastomer seals 140, 150. In this case, there will be zones Z2 and Z1 which will offer less sound and thermal insulation and no insulation against drafts. This configuration allows only a displacement of leaves 2 and 3 according to a

  direction parallel to the axes X'-7 and Y7 of the rails 7.

  This system advantageously uses profiles of commercially available shapes, to which it suffices to add a relief 15. It is also possible to use a solid element 9, of variable shape and section. In this

  case element 9 does not form an insulating partition.

  Similarly, the shape and size of the reliefs 14 and 15

is variable.

  In another configuration, each leaf 2 or 3 comprises in the upper part above the roller 11 a

thermal cut-out device.

  In another configuration mode, rollers 11 oscillating around an axis 12 are no longer used but, for example for the rails in the upper part, pendulum rollers 11. As a variant, the rollers 11 are mounted

  so as to be able to move on their axes 12.

  The means for locking the leaves in the closed position are, for example of the cremone bolt type, of the "bellows chassis" type, with cams, with cam deflection or with magnetic closure. The leaves can receive, at their ends in contact with part of the frame at the end of movement

leaves, stepped stops.
