DEVICE FOR CLOSING A SLIDING RACK COMPRISING A MANEUVER BOX AND A STRIKE

INTEGRATED IN A SLEEPING CHASSIS

Field of the invention

The invention relates to the field of sliding doors or windows also called sliding bays, of which a sash frame is configured to slide in a fixed frame frame. In particular, the invention relates to a sliding opening fitted with a closing device making it possible to prevent the opening frame from sliding relative to the frame frame.

State of the art

Sliding bays are known comprising a sash frame carrying a panel, in particular glazed and slidably mounted in a frame frame. In a sliding bay opening position, the sash frame leaves a passage between it and the frame, and in a sliding bay closing position, the sash frame and the sash frame cooperate to close off said passage.

Conventionally, the sliding bays are also equipped with a closing device having a locked position and an unlocked position. In the locked position, the closing device prevents the passage from the closed position to the opening position of the sliding door, inter alia it prevents the sliding of the sash frame in the frame of the frame. Conversely, in the unlocked position, the closing device allows the sliding of the sash frame in the frame frame.

In general, the closing device usually comprises a keeper fixedly mounted in the frame, a maneuvered part controlled by a maneuvering part equipped with a control button. The maneuvered part comprises a maneuvering box, a member movable in vertical translation, in particular a rod or a slide, equipped at least with a bolt. The whole of the operated part and the operating part is conventionally mounted in the sash frame, or more exactly in a sash upright.

The frame frame and the sash frame often consist of rigid metal or plastic profiles or a combination of these materials, which frame the glass panel on four sides. Vertical sections of the frame frame and the sash frame are respectively called a frame amount and a sash amount. The latter are able to cooperate with each other in the closed position of the sliding bay.

However, the integration of the operating part and of the operating part in the opening upright requires a substantial width thereof around the glazed panel, which affects the aesthetics and the thermal insulation of the sliding window. and limits the clear glass, that is to say the panel surface through which the light passes. The width of the opening upright is understood to mean the dimension of the opening upright in the sliding direction of the opening frame. Furthermore, the profile is generally a less good thermal and sound insulator than the glazed panel, and even more so when it is equipped with an operating box with control means, often metallic.

In order to partially overcome the aforementioned drawbacks, sliding doors or windows with a hidden sash are proposed, the sash frame of which is fitted into the frame frame in the closed position. Such sliding doors or windows have the advantage of offering a more aesthetic solution with improved thermal and sound performance. They also have the advantage of comprising a burglar-resistant shield, constituted by a portion of the frame of the frame embedding the sash frame, which hinders access to the points of weakness of the closing device. However, this solution is not satisfactory insofar as it is content to limit the aforementioned drawbacks by hiding the amount of sash in the frame amount, but the width of the sash amount is no less important.

Objectives of the invention

An objective of the invention is to produce a sliding opening, the width of the sash amounts being reduced compared to the state of the art so as to maximize the clear of glazing.

The invention also aims to provide a sash frame having greater thermal and sound insulation as well as a lighter aesthetic appearance than conventional devices.

Another objective of the invention is also to make a sliding bay more aesthetic, more ergonomic, and whose handling is intuitive.

General description of the invention

The invention relates to a sliding opening comprising a sash frame slidingly mounted in a fixed frame frame, and a closing device. This closing device comprises an operating part equipped with an operating box, and an operating part adapted to form a fixed connection with a fixed element in a locked position, under the control of the operating part. According to the invention, the maneuvered part comprises at least one means of cooperation with the fixed element, said means being chosen from a bolt or a keeper, and that the maneuvering unit and the keeper are integrated in the frame of the frame.

Such a sliding bay has the advantage of avoiding the integration of the operating box and the striker in the sash post, which makes it possible to reduce the sizing of the sash frame. The area of the panel masked by the sash frame is thus reduced.

This means that the free area of the panel through which the light passes, in other words "the glazing clear", is maximized.

In addition, in general, the profiles constituting the sash amount have a thermal and sound insulation capacity which decreases when they are equipped with an operating box, often metallic. Thanks to the invention, the sash upright is now devoid of the operating box, which improves the thermal and phonic performance of the profiles. In addition, the opening frame according to the invention is lightened and thus requires less effort to slide it into the frame frame.

In addition, the operated part is designed according to two variants, namely either the bolt or the strike cooperating with the movable element, which allows a user to choose the variant best suited to a defined sliding bay.

According to an advantageous, but optional feature of the invention, the frame of the frame comprises a cavity opening onto one face of a frame amount disposed opposite a sash amount, the operating unit being placed in said cavity. Thus, a large part of the operating box is hidden by the frame upright, which improves the aesthetic appearance of the sliding door. In addition, once the sliding door is closed, the housing is neither accessible nor visible on either side of the sliding door, which prevents any deliberate damage to the housing, especially from the outside, in view of 'open the sliding door. It is therefore an effective solution for securing the locking device.

According to one embodiment of the invention, the maneuvered part comprises a movable element and the bolt, the movable element being connected to the bolt and mounted movable in vertical sliding in a sash upright, and the fixed element consisting of the keeper mounted fixed to an amount of frame. Thus, in the closed position of the sliding bay and under the action of the operating part, the mobile element slides up or down so as to allow a fixed connection of the bolt with the keeper in the locked position or to release said link in the unlocked position.

Advantageously, but optionally and in the same embodiment, the opening amount comprises two side walls extending in a sliding direction of the opening frame, each of these walls comprising a protrusion defined in a transverse direction, perpendicular to the sliding direction of the opening frame, the side walls and the protuberances delimiting a second housing in which the movable element slides. Thus, the side walls and the protrusions, surrounding the mobile element, allow a single displacement along the vertical of the mobile element in the housing.

According to another embodiment of the invention, the maneuvered part comprises a mobile element and the keeper, the mobile element being connected to the keeper and mounted in translation vertically in a frame upright, and that the fixed element is constituted of the bolt fixedly mounted on an upright. Thus, unlike the previous embodiment, the keeper is movable so as to cooperate with the bolt by a fixed link in the locked position or to release this link in the unlocked position.

According to an advantageous, but optional feature, in the same embodiment, the frame upright comprises two side walls extending in a sliding direction of the sash frame, each of these walls comprising a protrusion extending in a direction transverse, perpendicular to the sliding direction of the sash frame, the side walls and the protuberances delimiting a first housing in which the movable element slides. Thus, the housing, as produced, has the same advantages as the previous embodiment.

Advantageously, but optionally, a control button for the maneuvering part is integrated in the frame amount. Deporting the operating part in the frame frame rather than in the sash frame further reduces the sizing of the sash frame. In addition, users conventionally take support with one hand on the frame of the frame to have more force to handle the opening frame with the other hand. Thus, the hand resting on the frame is already positioned to manipulate the operating part. In other words, the integration of the operating part in the upright of the frame makes the handling of the sliding window more intuitive. Furthermore, in the example of the sliding bays comprising a handle placed on a panel carried by the sash frame, the integration of the operating part in the frame of the frame makes it possible not to combine it with the handle, this which leaves more freedom in the ergonomic and aesthetic design of the handle.

Advantageously, but optionally, the maneuvering part includes a key type condemnation. Thus, the actuation of the operating part is reserved for the user having a key. This further secures the closing and opening of the sliding door.

To simplify the description which follows, it should be noted that, in the figures, the same references designate the same elements.

Detailed description of the invention

In FIG. 1 is shown a sliding window 1 oriented according to three orthogonal vectors, a vector X extending in a longitudinal direction F2 of the sliding window 1, a vector Y extending in a transverse direction F3 pointing from an interior face I towards an external face E and a vector Z extending in a vertical direction F1 pointing from bottom to top of FIG. 1. In this document, the terms “upper” and “lower” “high” and “bottom” are defined with respect to the vertical direction F1. By "exterior" and "interior" we mean the space respectively outside and inside a building where sliding door 1 is installed.

The sliding window 1 comprises, here, two sash frames 2 and a frame frame 3 secured to the main structure or the frame. Each opening frame 2 carries a glazed panel 5, the opening frame assembly 2 and the glazed panel 5 is called a leaf 6. Each leaf 6 is slidably mounted in the longitudinal direction F2 on rails in the chassis of the frame 3 so as to allow the leaves 6 to cross.

As a variant, the opening consists of one or more leaves 6 of the same dimensions or of variable dimensions which move respectively on rails which are parallel to each other and spaced substantially the thickness of a leaf to allow the leaves 6 to cross.

Referring to Figure 1, the frame 3 has two frame uprights 30 defined in the vertical direction F1 and arranged on either side of the sash frame 2.

The sash frame 2 consists of rigid metal profiles such as aluminum, wood, plastic or a combination of such materials, which frame the glass panel on four sides 5. The vertical rigid profiles constitute uprights of opening 20 which are in front of the uprights of the frame 30. The sliding bay further comprises a closing device 4 (partially visible in FIG. 1) preventing the sliding of the leaf 6, or exactly of the opening frame 2, in the frame 3.

With reference to FIG. 2 and to FIG. 3, the closing device 4 comprises an operating part 41, an operating part 42 and a fixed element. In the example illustrated, the fixed element consists of two strikes 43 fixed on the frame upright 30. We call them: the upper strike and the lower strike.

The operating part 41 of the closing device 4 is placed in the frame upright 30. It comprises, here, a control button 411 movable in translation, in the vertical direction F1, in a frame 412 having an L-shaped profile. 411 is connected to a cam 413 placed in a maneuvering box 415. The cam 413 is itself connected to a movement transmission part 414, otherwise called “a square” according to the vocabulary of the Men of the Trade in this field . The movement transmission part 414 is also disposed in the maneuvering unit 415. The latter also comprises a gear system (not shown) and a control means 416, illustrated in FIG. 4, mounted movable in translation along the vertical direction F1. In the example illustrated, the frame upright 30 comprises a cavity 35, illustrated in FIG. 8, opening onto one face 351 of the frame upright 30 disposed opposite the sash upright 20 in order to receive the operating unit 415.

The maneuvered part 42 is placed in the opening upright 20. It comprises a movable element which is, here, a rod 422 mounted movable in translation in the vertical direction F1. Each end 423, 424 of the rod 422 carries a bolt 44, here having a mushroom shape. Thus, in the example, we have two bolts 44: an upper bolt and a lower bolt arranged respectively opposite the upper strike and the lower strike. The maneuvered part 42 further comprises a connecting means 425 housed in the thickness of the rod 422. The connecting means 425 is connected to the control means 416 of the operating housing 415 so as to allow an ascent or a descent of the rod 422. These two elements are illustrated in FIG. 4. The control means 416 comprises, here, two pinions 417 projecting from the operating housing 415 and oriented towards the rod 422. The connecting means 425 is a hollow part having an elliptical section in which pinions are embedded. The connecting means 425 is inserted into a hole 426 made in the thickness of the rod 422.

FIG. 5 illustrates the upper strike 43 and the upper bolt 44. To simplify the reading, the description of these two elements applies equally to the lower strike and to the lower bolt. The upper strike 43 is fixed in a housing 325, illustrated in FIG. 6, of the frame upright 30 by means of two top and bottom clips 431. In the example illustrated, the upper strike 43 is a buttonhole strike. The keeper 43 comprises a slot 432 consisting of two portions, including a first portion 433, disposed at the bottom, allowing the cap 441 of the upper bolt 44 to pass, and a second portion 434, arranged at the top, being a retainer for this cap 441.

We will now describe the operation of the closing device 4 in order to lock or unlock the sash frame 2.

By moving up or down the control button 411, it rotates the cam 413 which then rotates the movement transmission part 414. This part, by rotating, actuates the system gear, disposed inside the maneuvering housing 415 so as to allow a translational movement along the vertical of the control means 416. Then, the control means 416, by its movement, causes the rod 422 carrying or lifting bolts 44.

The locking and unlocking of the sash frame 2 is carried out when the sliding window 1 is closed. In the example illustrated, given the configuration of the strike 43, the control button 411 located at the bottom corresponds to an unlocked position of the sash frame 2. Conversely, the sash frame 2 is locked when the control button 411 is positioned at the top. Indeed, when the control button 411 is located in the low position, the cap 441 of the bolt 44 is inserted in the first portion 433 of the keeper 43, which allows the disengagement of these two elements, therefore the sliding of the chassis d opening 2. On the other hand, when the control button 411 is placed from bottom to top, the cap 441 of the bolt 44 is engaged in the second portion 434 of the keeper 43, which forms a fixed connection between the bolt 44 and the keeper 43 and thus prevent sliding of the sash frame 2.

Referring to Figures 6 and 7, the frame upright 30 comprises three sections: an inner section 31, an intermediate section 32 and an outer section 33. The intermediate section 32 comprises two side walls 321, 322 extending in the direction of sliding F2 of the opening frame 2. Each of these walls comprises a protrusion 323, 324 defined in the transverse direction F3. A first housing 325 is delimited by the side walls 321, 322, and the protrusions 323, 324. The upper and lower strikes 43 therefore come to be positioned in this housing 325. In the example illustrated, the strikes 43 include a groove 435 which allows the growths 323, 324 to engage there. This therefore makes it possible to strengthen the fixing of the strikes 43 to the frame amount 30.

The opening amount 20 also includes a second housing 225 in which the rod 422 slides. This second housing 225 is formed by side walls 221, 222 extending in the longitudinal direction F2 and protrusions 223, 224 extending according to the transverse direction F3.

The cavity 35 into which the operating housing 415 is inserted is illustrated in FIG. 8. The intermediate section 32 includes the cavity 35 opening onto one face 351 of the frame upright 30 disposed opposite the opening upright 20. The housing 415 , once inserted into the cavity 35, is then machined to be fixed to the frame upright 30. For example, the machining of the operating box 415 is manifested by a notching operation in order to obtain a dimensioning of said housing which is compatible with that of the cavity 35.

Figures 9 to 14 illustrate a second embodiment of the closure device 4 according to the invention.

The closing device 4 always comprises three parts: the operating part 41, the operating part 42 and the fixed element. With reference to FIGS. 9 and 10, the operating part 41 is placed in the frame upright 30. The control button 411 interacts with the operating box 415 in the same manner as that described in the first embodiment. In fact, the movement in translation in the vertical direction of the control button 411 causes the control means (not shown) to go up or down from the control unit 415.

According to the second embodiment, the maneuvered part 42 comprises the movable element, which is here the rod 422, mounted movable in translation in the vertical direction F1. Each end 423, 424 of the rod 422 carries a keeper 45. Thus, we have here, an upper keeper and a lower keeper. The rod 422 is placed in a housing 325, shown in FIG. 12, of the frame upright 30 and it is closely linked to the operating box 415 via the cooperation means (not shown).

In the example illustrated, the fixed element consists of an upper bolt and a lower bolt 46 arranged respectively opposite the upper strike and the lower strike 45. The lower and upper bolts 46 are fixed here to the upright opening 20.

The upper bolt 46 and the upper strike 45 are illustrated in FIG. 11. The description of these two elements applies equally to the lower strike and to the lower bolt. In the example illustrated, the bolt 46 has the shape of a hook 461 while the keeper 45 comprises a rectilinear slot 451 followed by a stopper 452 placed below.

The operating principle of the closure device 4 remains substantially identical to that described in the first embodiment. By the vertical displacement of the control button 411, the rod 422 is caused to slide in the housing 325 of the frame upright 30.

The locking and unlocking of the sash frame 2 is carried out when the sliding window 1 is closed. In the example illustrated, given the configuration of the keeper 45, the control button 411 located at the bottom corresponds to a locked position of the sash frame 2. In this position, the hook 461 of the bolt 46 is locked by the keeper 452 of the keeper 45, which forms a fixed connection between the bolt 46 and the keeper 45 and thus prevents the sliding of the sash frame 2. On the other hand, the sash frame 2 is unlocked when the control button 411 is positioned at the top. The control button 411, by sliding upwards, deliberates the hook 461 of the stopper 452, which allows the disengagement of the sash frame 2 from the frame frame 3.

With reference to FIGS. 12 to 14, the configuration of the sash upright 20 and the sash upright 30 remain identical to those described in the first embodiment. However, according to the second embodiment, the rod 422 now slides in the first housing 325 of the frame amount 30 while the bolt 46 is fixed to the opening amount 20 in the second housing 225.

In the example illustrated, the outer profile 33 of the frame upright 30 has a projecting portion 330 covering an outer profile 21 of the sash upright 20 in the closed position of the sliding window 1. The protruding portion 330 covering the amount of opening 20 protects the opening 20 of the thermal gradients by stopping the sun's radiation before they reach the opening 20 so as to limit the expansion of the amount due to the thermal gradients. In addition, the projecting portion 330 constitutes a burglar-resistant shield hindering access to the points of possible weakness of the closure device 4.

Of course, it is possible to make numerous modifications to the invention without departing from the scope thereof.

The closing device can be integrated in another location of the frame. For example, the maneuvering part can be placed in one of the profiles arranged in the longitudinal direction F2, otherwise called horizontal profiles. In this example, the maneuvered part must be positioned so as to be able to cooperate with the maneuvering part.

The closure device may include another type of control button. For example, it may be a lever with a twist handle. Thus, in this example, we need a mechanism for transforming a rotational movement of the handle into a translational movement of the movable element. This mechanism is in itself known to the skilled person.

The closing device can have a number of secure points corresponding to the number of striker-bolt pairs. For example, it may include three secure points corresponding to the three pairs of keeper 10 upper, intermediate and lower bolt. There is no limit to the number of secure points.

In another exemplary embodiment of the invention, the sliding bay can comprise an operating box comprising an anti-picking mechanism and an anti-false operation mechanism.

In one example, the closure device comprises an interior operating part and an operating part accessible from the outside. This can have a key-type lock to secure the opening of the sliding door.
