This invention relates to a case for counterframe for disappearing sliding door, and counterframe with case having a space that houses the door panel, provided with at least one side which allows the robust fixing of plugs for the support of hanging objects.
At present, there is a wide spread of doors and windows of the sliding type, a solution that can be used in many architectural solutions, especially in those where the reduction of interior spaces together with a minimalist trend are relevant elements in the design of the building. By using these types of doors and windows, it is also possible to use those spaces that on the other hand should be kept free to allow a conventional opening of doors on hinges.
In principle, the sliding doors of the disappearing type are structured in such a way as to comprise a series of fixed elements, intended to be integrated in the wall structure or even to constitute, being coated, a wall, and a series of movable elements, which are intended to be used during the installation phase of the door, to be removed afterwards. In substance, for example a counterframe is integrated as a fixed element in the wall structure. The conventional counterframe is made up of at least one large case, that defines a space, and houses the door panel once it is slid into the opening position. There is also a rabbet jamb intended to be anchored to the wall in correspondence of the vertical profile of the doorcase, opposite to that of positioning of said large case, in such a way as to allow, once closed, that the door panel itself abuts against it. Furthermore, above the large case an upper crosspiece is engaged, being joined to said load bearing structure, which supports a longitudinal guide track. It is necessary to provide a guide track in order to allow the effective opening and closing movement of the sliding door that is hanging by means of conventional means, usually of the trolley type.
In conclusion, the counterframe only replaces a portion of wall, in such a way as to be able to contain the door. Once plastered, in fact, it becomes absolutely uniform with the wall portion that it has replaced, with a thickness that is equal to that of the boardings, in such a way as to obtain completely planar partitions. However, as the structure of these counterframes is made up, in general, of zinc-coated steel plates, stiffened by ribbings, coated with metal meshes to bond the plaster, it is not possible to anchor by means of conventional fixing techniques sanitary equipment or electrical sockets, unless one uses a model specific to the passage of pipes and electrical wires. In the same way one cannot hang pieces of furniture to be fixed with plugs, such as kitchen wall units, small cabinets and others, which are essential furniture elements.
In order to solve some of these problems, the same applicant in
In the same way in ITTV2008A000023 (De Faveri) a counterframe for a disappearing sliding door for exteriors and interiors is further described, comprising a large case arranged to receive the plaster or plasterboard coating, an upper crosspiece holding the guide track, a rabbet jamb profile that houses the doorpost, wherein at least the rabbet jamb profile is the fairlead technical profile with, on the side facing the large case, a continuous and rectilinear deep U-shaped seat, inside which at least one tubular duct is longitudinally received, held inside said U-shaped seat by clips and with, along the base of the U-shaped seat, removable perforated sheet-metal portions. In another version of the counterframe for sliding door, the upper crosspiece holding the guide track supports the supporting box with or without internal split box, the box being obtained by coupling two sheet-metal panels closed at the two ends by bases to which the upper fixing ends of the box on the one hand and of the rabbet jamb profile on the other hand are joined.
From what has been stated above, one should consider as known:
Therefore, one may agree on the fact that the counterframes for sliding door currently on the market solve the problem of the electrical wiring, having sides that are prearranged for the support of the electrical boxes, as well as on the fact that the counterframes always offer the possibility to advantageously support the supporting box with or without internal split box, nevertheless at present the problem of the fixing along the side of the space for housing the door panel, wall units, small furniture and other hanging objects is not solved, it being a significant problem in the context of an objective demand for functional furnishing.
Considering all this, the companies of this sector reasonably need to find innovative solutions able to overcome at least the just mentioned problem.
In accordance with the invention, there is provided a case for counterframe for disappearing sliding door provided with a side for supporting hanging objects, the case being of the type comprising:
In this way, by means of the considerable creative contribution, the effect of which constitutes immediate and non-negligible technical progress, various and important aims are achieved.
A first aim consists in allowing, behind the side definition wall of the counterframe inside which the space for housing the door panel of the disappearing sliding door is obtained, therefore with very reduced thicknesses useful for support, the support by drilling of the side, of wall units, shelves, and anyhow of any other hanging object, ensuring their good capacity and stability over time.
A second advantage can be referred to the fact that this operation of fixing by means of plugs can be carried out, not only localised, but in any point of the surface of the side of the counterframe. Therefore, it can be pointed out that the so obtained and described counterframe substantially overcomes those architectural barriers that until today have prevented its use in furnishing contexts or by necessity, as in the latter case where one must fasten for example a security handrail.
Furthermore, it can be seen that this particular layered structure allows the housing and the passage of water pipes and electrical cables, in any point of the wall. Where this function is required, one can provide panels with suitable seats or alternatively processing can be carried out at the company, upon customer request, to create the seat in correspondence of the side of said counterframe for disappearing sliding door.
Said advantages can therefore be conveniently integrated in a more complex counterframe for disappearing sliding door, provided with the advantages typical of the solutions that use a case and rabbet jamb to support the electrical boxes, the respective wirings and water pipes. And still in those counterframes in which said crosspiece supports the supporting box with or without internal split box of the air-conditioning system.
In conclusion, these advantages have the non-negligible value of obtaining a counterframe for disappearing sliding door with a good technological content, that allows excellent integration in an aesthetic environment without setting architectural limits from the point of view of the possibility to install equipment on the surfaces that delimit it.
These and other advantages will appear from the following detailed description of at least one preferred solution with the aid of the enclosed schematic drawings whose details of execution are not to be considered limitative but only illustrative.
This invention relates to a case (10) (
The case (10) (
On each side (a, b) of the case (10), in correspondence of the face (123) facing outwards of each of the side definition walls (120) of the case (10), in the space interposed between said side definition wall (120) and the finishing supporting element such as the plaster mesh (17) that is supported by cross beams (16), a first layer of semi-soft material (14) is placed, consisting of plastic or similar material, that serves as an expansion chamber for the final part of the fixing plugs and as a limit warning (stop) for the wall drilling phase. On said first layer of semi-soft material (14), a second layer of rigid material is superimposed (15), of woody, plastic or similar material, in such a way as to serve for the clamping of the gripping part of the fixing plugs.
A series of cross beams (16) are interposed at a determined distance from one another, of rigid ferrous, plastic or similar material, that are used to space out the plaster (130) mesh (17) of rigid ferrous, plastic or similar material and to fix the same by means of suitable processing. In this case, there is an exceeding part (170) of the mesh (17) that protrudes beyond the back part (11) of the case (10) which has the aim of preventing the formation of cracks between the counterframe for disappearing sliding door (100) (
As far as the back part (11) (
In a second hypothesis it is also possible to make the version of the counterframe for disappearing sliding door for plasterboard walls. In this case, the finishing supporting element such as the plaster mesh (17) is replaced and the plasterboard sheets are laid directly on the cross beams (16) of ferrous, plastic or similar material, to which they are then fixed by screwing with suitable commercial screws and following finishing plastering. In this case, too, the support, for example of the wall units (200) (
