Description

Sliding door with telescopic guide retractable

The present invention aims at a Sliding door with retractable telescopic guide.

The proposal has particular application although not exclusive in the enclosure sector.

Scope

Type enclosures are known slider Such enclosure solutions, with particular reference to sliding type doors, find a use specific in the structures of buildings in which it is already planned the installation of a separation of the interior spaces to allow the use of this surface than otherwise it should be reserved to allow the opening, without obstacles, of a conventional pivoting door on bolts

State of the art

In this area, for example, the sliding doors of retractable type. You are normally require the use of a counterdriver, which comprises a series of fixed elements intended to be integrated into the structure of the wall, and a series of mobile elements, intended to be used during the commissioning phase and then be eliminated in a second phase. Substantially, there is a Counter-counter that must be integrated into the structure of the wall. The mentioned fixed elements that are part of the counterframe, are provides that they are associated with the structure of the wall and include less a box destined to constitute the structure in the form of box inside which the door plan will be contained a once it is slid to the open position, in addition of a striking stringer intended to be anchored to the wall in correspondence with the vertical profile of the door frame opposite to the positioning of the mentioned drawer, to allow, once put in the closed position, that the door itself is put behind this one. In order to allow such movement, in the upper part of the drawer itself is arranged, being bolted to said support structure, a crossbeam that supports an underlying longitudinal guide or a rail. In this case, in the sliding lane through the appropriate carriages, will be the door suspended.

Finally, telescopic guides are known. Conventionally, they have been largely used for realization of household appliances, see for example the common dishwashers, in order to enable the extraction of Washing baskets In other hypotheses, in the realization of furniture complements, such as the comfortable ones provided with particular depths. The role of these guides telescopic, both in the first and second of these two hypothesis, is to allow cantilever support of a container, which can be the basket or the drawer, with respect to the main containment structure, speeding up access. The solutions described must obviously be provided with a double guide, one for each of the two sides of the basket or the drawer and where each guide is composed of a first element in "C" arranged behind the relative wall of the structure main containment, within which a second element Supported by spheres or casters is sliding and mobile so longitudinal with respect to the first, said second element is arranged on the corresponding flank of said basket or drawer.

Also in the patent literature they have drawn up proposals for solutions that aim at structures of guide rail of telescopic type among which by way of example in US2005174022 (Kuttalek) a lane or a telescopic, horizontal or vertical extension of an element of a closet, the door of an oven or similar appliance. Said telescopic extension comprises at least one external rail in sheet and a sliding rail also in sheet, which exceeds partially the outer lane and can be replaced along the External lane through an anti-friction support. The extendable rail includes an external fixing rail which is connected to through reinforcements to the external lane and / or an additional lane connected, which is connected to it and placed under the Sliding rail reinforcement. The telescopic extension includes two interconnected lanes.

An additional solution is found in EP0538181 (Corrie), which describes a guide rail for doors Slides particularly for sliding doors of cabins shower. In summary, the proposed solution comprises an edge of door that defines a first fixed profile and a second profile open, which defines a guide rail, which is slidable with regarding a first section acting as a framework which passes to be extensible so as to be able to match the openings of different width. Two door leaves are mounted in such a way that slide hooked to the guide rail, so that the first sheet is mounted to perform a sliding movement relative to the second sheet and the two sheets can perform a movement of sliding relative to the guide rail.

Another solution, commercially known, provides that a sliding door of the type with external sliding to the wall is provided with a guide rail for the movement of the blade, This guide rail is unique, of the type with gallery and is of length equal to twice the door itself to match the measure of the section which must be closed and to extend beyond it throughout the entire measure of the width of the door.

Drawbacks

The known state of the art shows how all the proposed solutions present, more or less Broad limitations.

The limitations, in fact, are recognizable in sliding door solutions that include the use of counter-drivers, which although they are surely significant, allow to provide an adequate response to the expectations of the public, however they require substantial intervention on the mural structure separating the rooms in the buildings. As for practice, therefore, a workforce is required qualified with intervention costs rather important.

Also the solutions referring to the aforementioned Patent documentation has limitations. More precisely, the solution concerning patent EP0538181 (Corrie), in the The opinion of the applicant is not optimized in terms of containment requirements of the spaces for the projection of obstacles In addition, the solution, as structured, does not seem be adapted to allow the support of normal loads as in the case of door leaves conventionally used to separate rooms interiors of the buildings, in addition the solution is planned predisposed to carry out the support and the sliding of two  leaves.

As regards the suggested solutions in the furniture accessories sector, as well as to the cited patent US2005174022 (Kuttalek), these are totally unsuitable for other purposes or purposes, particularly when these try to be transferred to the equipment for doors of buildings

In addition, all known solutions of sliding doors for buildings and in particular those that provide for mounting an external guide rail as a gallery, which provides a double length with respect to the section of the door of which they constitute the equipment, they are outstanding and are permanently in sight so that they come to affect the aesthetics of the wall to which they are attached.

From here, the need for companies, in particular sector, to identify alternative solutions, more very effective, with respect to the existing solutions until the moment.

An objective of the present invention is also that of avoiding the inconveniences described.
