Description

SLIDING SYSTEM FOR DOORS OR SHUTTERS

This invention relates to a sliding system for closing an opening comprising a panel which is slidably arranged with the aid of a rolling body in a running rail relative to an adjacent wall or other panel. The panel is preferably a sliding door for a wall or cupboard or a hatch (sliding hatch) as a screen for a window.

Sliding shutters or sliding doors are usually used to close cupboard, window or door openings. They are usually built up by a wall element (panel) that can be moved back and forth in a running rail with the aid of walking rollers, provided on a rolling body. Sliding systems are known whose wall elements (e.g. shutters or doors) are slidable relative to each other, or relative to an adjacent wall. In the case of two hatches or doors that move relative to each other, the panels will each slide in a different running rail. Because the running rails are arranged in front of each other, one panel will slide in front of the other.

The above systems, however, have the disadvantage that the slidable parts do not coincide in one and the same plane with either the adjacent walls or the adjacent panel, which of course is not aesthetically optimal.

The object of this invention is therefore to provide a sliding system of the type described in the first paragraph of this description, which can be opened in a simple and smooth manner and which, when it closes an opening, coincides in one plane with the surrounding wall, wall or other sliding door or hatch.

The object of the invention is achieved by providing a sliding system for closing an opening comprising a panel which is slidably arranged with the aid of a rolling body in a running rail relative to an adjacent wall or other panel, wherein the rolling body is rotatable swivel arm is connected to the panel in such a way that the panel can be moved by rotation of the swivel arm between a position of use in which the panel is slidable in the running rail and a rest position in which the panel falls in the same plane as the adjacent panel or wall. In the position of use, the swiveling arm will preferably extend according to a first direction, and in the rest position extend according to a second direction transverse to the first direction. The panel is preferably a sliding door or sliding door.

In a preferred embodiment of the sliding system according to the invention, the system further comprises a toothed bar and said pivoting arm comprises a toothed wheel with a series of teeth which are provided for engaging the toothed profile of the toothed bar to move the panel between its position of use and rest position . Preferably, the ratio of the number of teeth on the rack and the number of teeth of the gear is 1/4. In particular, the rack comprises at least three teeth and the gear comprises at least twelve teeth. In particular, the toothed bar is provided on the running rail. In an alternative embodiment, the toothed bar can optionally also be mounted against an adjacent wall or wall.

The aforementioned ratio 1/4 in which, for example, a gear with twelve teeth engages in a toothed bar provided with three teeth, will result in a rotation of 90 °, which will move the swivel arm between the position of use and the rest position.

According to a special embodiment of the sliding system according to the invention, the pivotal arm is connected to the rolling body via a resilient element, the resilient element being provided for resiliently holding the pivotal arm in the position of use. The resilient element is preferably a torsion spring. In an alternative embodiment, the swiveling arm is connected to the roller body via a snap connection.

In a most special embodiment of the sliding system according to the invention, the system further comprises a locking element provided to keep the swiveling arm in rest position.

According to a particularly advantageous embodiment of the sliding system according to the invention, the roller body comprises a first and second pair of running rollers, which are connected to each other via a first and second axis, the said axes extending at a different height. Such a roller body ensures that the panel connected thereto will not fall despite the decentralized suspension.

This invention will now be further elucidated with reference to the following detailed description of a preferred embodiment of a sliding system according to the present invention. The purpose of this description is only to provide clarifying examples and to indicate further advantages and details of this embodiment of a sliding system, and can therefore in no way be interpreted as a limitation of the scope of the invention or of the patent rights claimed in the claims. .

In this detailed description reference is made to the accompanying drawings by reference numerals, wherein: figure 1 is a principle sketch of the sliding system according to the invention; figure 2 is a perspective representation of the sliding system according to the invention; figure 3 is a detail representation of a rotatable pivotal arm which is connected to a roller body via a torsion spring; figure 4: a partial representation of a sliding system according to the invention comprising two panels (shutters) that can be moved relative to each other.

The sliding system (1) according to the invention, which is shown inter alia in figure 2, is provided for closing an opening in a wall or a cupboard, or window opening. To this end, the sliding system (1) comprises a wall element (panel) in the form of a hatch (2, 3) or door which can be slid back and forth in a running rail (5) with the aid of rollers provided on a roll body (4) . In the figures shown, two sliding (panel) shutters (2 and 3) are each shown. However, it is evident that within the scope of this invention the second hatch (3) can be replaced by a fixedly arranged hatch, or by a part of an adjacent wall or wall element.

With the sliding system (1) according to the present invention, it becomes possible to move a sliding hatch (2) such that it falls into the same plane as the adjacent sliding hatch (3) or wall. In a specific embodiment, such as shown in Fig. 1, the rear (second) hatch (3) can for instance be shifted left and right, and this without hindering the other hatch (2). This can be achieved by having the two hatches (2, 3) each slide in a different running rail. The front (first) hatch (2) is mainly shifted in one direction and is only moved at the last moment in the available space next to and located in the same plane as the second hatch (3).

In order to make the displacement possible, the rolling body (4) is connected to the sliding hatch (2) via a rotatable swivel arm (6) such that the sliding hatch (2) can be moved between a position of use in which the swivel arm (6) is rotated. sliding hatch (2) is slidable in the running rail (5), and a rest position, in which the sliding hatch (2) falls in the same plane as the adjacent hatch (3). During the movement of the hatch (2) in the running rail, the swiveling arm will extend in a first direction, corresponding to the direction in which the running rail (5) extends. When the swiveling arm (6) is in its rest position, it will extend in a second direction, transversely of the first direction.

In order to keep the pivotal arm (6) (resilient) in use position (wherein the pivotal arm extends in the first direction), the pivotal arm (6) is connected to the roller body (4) via a resilient element (9), preferably a torsion spring. ). Alternative possibilities for keeping the swivel arm (6) in the position of use, e.g. via a snap connection, naturally also fall within the scope of this invention.

To now move the swivel arm (6) to its rest position, in which the hatch (2) connected to the swivel arm (6) falls in the same plane as the adjacent sliding hatch (3), the sliding system (1) according to the invention comprises on the one hand a toothed bar (7) and, on the other hand, said pivotal arm (6) comprises a gear (8) with a series of teeth which are provided for engaging the tooth profile of the toothed bar (7). The ratio between the number of teeth of the toothed rack and the number of teeth of the gearwheel is 1 in 4. In the figures, the hatch (2) on its upper side, at the level of the ends, is provided with such a whole of roller body, swivel arm, spring, gear and rack. When the sliding hatch (2) enters the rail (5) almost at the end of its path, the teeth of the gear wheel will engage with the toothing of the toothed bar. As a result, the swiveling arm (6) will rotate 90 ° to its resting position. The rotary movement will also cause the spring to rotate (against the spring force).

By rotation of the pivoting arm (s) (6), the hatch (2) connected to the pivoting arm (s) (6) will now lie in the same plane as the adjacent one instead of in a plane immediately preceding the adjacent hatch (3). hatch (3).

When the swiveling arm (6) is in the rest position, both rolling bodies (4) will click into a locking element (stopper). These locking elements help hold the hatch (2) so that the (torsion) springs (9) do not pull it back. Only when the rolling bodies (4) are pulled out of the clamping elements of the locking elements, will the (now tensioned) spring, the swiveling arm (6) move from rest position to use position, whereby the first hatch (2) again for the second hatch (3) ), and can be moved again.

The rolling bodies (4) used in the sliding system (1) according to the invention comprise a first (10) and second pair (11) of running rollers, which are connected to each other via a first and second axis, the said axes being mounted on extend a different height. In the illustrated roll bodies there are two sets of such rollers, namely a first set, on the left side of the roll body (4), consisting of a first (10) and second pair (11) of rollers and a second set, on the right side of the roller body (4) consisting of a first (10) and second pair (11) of running rollers. Because the shafts extend at a different height, the rollers (10) of the first pair are slightly higher than the rollers (11) of the second pair. This arrangement will ensure that the panel connected to the roller body (4) will not tilt with respect to the running rail and will continue to slide smoothly.
