Description

[0001] The present invention relates to a device for suspension fastening, particularly for sliding doors which are positionable in small compartments.

[0002] Currently it is known to provide door and window assemblies that use a case, positioned within a wall, inside which a door or a panel, also known as in-wall sliding door, is associated slidingly.

[0003] This solution enables to reduce the space occupation of the door in a room thanks to the possibility to make it slide into the case: it is thus possible to use the space adjacent to the door, which would otherwise be occupied by doors of the type that is hinged laterally to a frame.

[0004] In the background art, the case embedded in the wall usually comprises vertical posts, which define, together with lateral cross-members, a box for containing the panel or the door; with the application of a mesh which is external to the containment box, plaster is then applied.

[0005] A track protrudes above the box, along an axis which is longitudinal to the box and is extended in the opposite direction with respect to the containment box, and is concealed by a jamb.

[0006] Carriages are associated slidingly within the track and are coupled to the upper edge of the door to allow their sliding in and out of the case.

[0007] An additional post is usually associated with the end of the track that is not associated with the vertical posts and acts as a terminal for the location and abutment of the front edge of the door.

[0008] One problem observed in the use of these solutions resides in that the size of the door must necessarily match the size of the compartment to be closed, since it is necessary to install the door after installing the case.

[0009] If one has to or wants to use a door having larger dimensions, or if it is necessary to install a door having preset dimensions in a smaller compartment, it is impossible to perform installation.

[0010] Italian utility model application no. F02001U0009, filed on 21 March 2001, is also known which claims an in-wall sliding door and the corresponding frame, of the type in which the door is suspended from a sliding track which makes it possible to arrange it in the open condition by transferring it into a metallic box designed to replace, with its space occupation, the corresponding wall portion, characterized in that in order to avoid the need to match the jambs, the cross-members and the corresponding joint covering borders to the aesthetic characteristics of each door that is chosen, the jambs and the cross-members of the new frame are shaped and arranged so as to define the compartment of the door in an offset arrangement and be visible only within the thickness of the wall, whose surface finish of the sides, with plaster or of another type, is extended so as to surround and delimit the compartment.

[0011] In this solution, when using doors that are wider than the compartment, in order to install or remove the door from the compartment the jamb that lies opposite the box must be defined by a fixed post B and by a removable post C, so that the temporary removal of the latter (Figures 2-6) allows the door to continue with the front edge beyond the normal abutment limit and enough to allow access to the rear edge.

[0012] Such solution suffers from the drawback of having to provide for the removal and subsequent installation of the post C on the post B; furthermore, the post C must be kept inside the post B by using two or more adjustable spacers E, which force the post C to press, with its wings C1, against the corresponding wings B1 of the post B.

[0013] All this increases the structural complexity of the solution; moreover, since it requires additional work, it increases the times and installation costs of the in-wall sliding door.

[0014] The aim of the present invention is therefore to solve the cited technical problems, by eliminating the drawbacks of the cited background art and thus providing a device that allows to install a door of the in-wall sliding type.

[0015] Within this aim, an object of the invention is to provide a device that enables to install rapidly and simply a door that has larger dimensions than those of a preset compartment.

[0016] Another object is to provide an in-wall sliding door that can be installed even by personnel that is not particularly trained.

[0017] Another object is to provide a device that is structurally simple, can be provided by means of ordinary systems and machines and has low manufacturing costs.

[0018] This aim, as well as these and other objects which will become better apparent hereinafter, are achieved by a device for suspension fastening, particularly for sliding doors which are positionable in small compartments, characterized in that it is constituted by a bracket, which is slidingly associable in a first seat that is provided longitudinally and above said door and has, at one end, means for rotary interconnection to an overlying carriage, slidable within an adapted track of a fixed case, and means for locking to the edge of said door.

[0019] Advantageously, the door has a second seat, which is provided longitudinally and in a lower region and is adapted to accommodate a pin which is arranged at the base of, and substantially flush with, the vertical posts of said case.

[0020] Further characteristics and advantages of the invention will become better apparent from the detailed description of a particular but not exclusive embodiment, illustrated by way of non-limiting example in the accompanying drawings, wherein:

[0021] In the exemplary embodiments that follow, individual characteristics, given in relation to specific examples, may actually be interchanged with other different characteristics that exist in other exemplary embodiments.

[0022] Furthermore, it should be noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer.

[0023] With reference to the figures, the reference numeral 1 generally designates a device for suspension fastening, particularly for doors 2 of the type that can slide because they are positionable in compartments 3 which have, in particular, smaller dimensions than the door.

[0024] The device 1 is complemented by a case 4, which is provided with an adapted mesh for applying plaster or plasterboard, which comprises vertical posts 5a, 5b which define, together with lateral cross-members 6, a box 7 for containing the panel or the door 2.

[0025] A track 8 protrudes above the box 7, along an axis which is longitudinal to the box 7 and is extended on the opposite side with respect to the containment box.

[0026] Carriages 9 are associated slidingly within the track 8 and are coupled to the upper edge 10 of the door 2 to allow its sliding in and out of the case 4.

[0027] An additional pair of posts 5c, 5d is usually associated with the end of the track 8 that is not associated with the vertical posts 5a, 5b; such posts act, together with an abutment band or element 11, which acts as a terminal for the abutment and location of the front edge 12 of the door 2.

[0028] The device 1 is also constituted by a bracket 13, which is essentially L-shaped and has a first arm 14, which is slidingly associable in a complementarily shaped first seat 15, which is provided longitudinally and above the door 2.

[0029] Preferably, the first seat 15 is constituted by a profile 16 which is C-shaped and is coupled in an upward region to the door, the complementarily shaped first arm 14 being slidingly insertable within it.

[0030] The bracket 13 is constituted by a second arm 17, which is plate-shaped and can be arranged adjacent to the edge 18 of the door 2.

[0031] The bracket 13 has, at an end which is adjacent to the second arm 17, means for rotary interconnection to said overlying carriage 9, such means being constituted by a first adjustment screw 19, whose shaft 20 can be inserted in an adapted hole provided in the second arm and whose head 21 is accessible to an operator for the fastening to the overlying carriage 9 in order to arrange the upper edge 10 of the door 2 at a chosen distance from the carriage 9.

[0032] The bracket 13 is provided, on the second arm 17, with means for locking to the edge 18 of the door, the means being constituted by second screws 22 that pass at adapted holes 23.

[0033] Additional means adapted to lock the arrangement of the first adjustment screw 19 are present on the second arm 17 and are constituted by a third locking screw 24, which interacts with the shaft 20 of the first screw 19 so as to prevent it from loosening and is thus intended to keep the door at the right height for its correct sliding.

[0034] The door 2 has a second seat 25 which is provided longitudinally and below it, preferably in a central region or even in an axially offset region.

[0035] A cylindrical pin 26 is positionable at the second seat 25, and protrudes from a guide 27 that is plate-shaped and is arrangeable transversely and substantially flush with the lower ends of the vertical posts 5a, 5b of the case 4.

[0036] The guide 27 has, in plan view, a rectangular shape with a pair of wings 28a, 28b at its ends, such wings being fixed to the vertical posts 5a, 5b by means of fourth screws 29a, 29b.

[0037] Operation is as follows: initially, the bracket 13 is inserted partially in the first seat 15 of the door 2 and then the carriage 19 is positioned in a region that is external to the box 7, as shown in Figure 5.

[0038] Then the bracket 13 is coupled to the carriage 9 by acting on the first screw 19, keeping the door inclined with respect to the compartment 3, whose dimensions are smaller than the width of the door 2.

[0039] Then the edge 22 of the door, always kept inclined, is moved closer to the vertical posts 5a, 5b, making sure that the pin 26 arranges itself at the second seat 25.

[0040] One then begins to position the door within the box 7, as shown in Figures 6 and 7, then gradually reducing its inclination with respect to the compartment 3 and pushing the door into the compartment; the partial insertion of the inclined door 2 in the box 7 is thus achieved until the door portion that is inserted in the box 7 allows the straightening of the door 2 at the compartment 3.

[0041] It has thus been observed that the invention has achieved the intended aim and objects, a device having been devised which, associated with an in-wall sliding door, allows the rapid and simple installation of an in-wall sliding door whose dimensions are greater than those of a preset compartment.

[0042] Furthermore, the described solution allows even personnel that is not particularly trained to install the in-wall sliding door, since the steps of installation are very simple and quick.

[0043] Finally, the device is structurally simple and can be applied simply also to doors and windows that have already been installed.

[0044] The invention is of course susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.

[0045] The materials used, as well as the dimensions that constitute the individual components of the invention, may of course be more pertinent according to the specific requirements.

[0046] The various means for performing certain different functions certainly do not need to coexist only in the illustrated embodiment but can be present per se in many embodiments, including ones that are not illustrated.

[0047] The characteristics indicated as advantageous, convenient or the like may also be omitted or may be replaced by equivalents.
