SUPPORT AND ANCHORING DEVICE IN SUSPENSION OF THE DOOR PANEL IN A FRAME FOR SLIDING DOORS

DISAPPEARED

[0001] The present invention relates to a device for supporting and anchoring the door panel in suspension in a counter frame for retractable sliding doors.

Field of application of the invention

[0002] The proposal finds particular though not exclusive application in the industrial sector for the production of accessory devices for doors and windows, particularly sliding type doors and windows.

[0003] With reference to doors and windows, the sliding doors of the retractable type are structured in such a way as to include a series of fixed elements, intended to be integrated into the wall structure, and a series of movable elements, the latter being intended to be used during the installation phase of the door and then removed at a later time. Basically, a counterframe, which can be of the plaster or plasterboard type, is integrated into the wall structure. The aforementioned fixed elements are expected to be associated with the wall structure and include at least one box or caisson intended to constitute the structure within which the door panel will be contained once it has been slid to the open position, as well as a jamb upright intended to be anchored to the wall in correspondence with the vertical profile of the door box opposite to that of positioning of the aforementioned box, in such a way as to allow, once closed, that the door itself goes to shelter on it. Furthermore, a longitudinal guide is engaged above the box itself, being screwed to said bearing structure. In order to allow the effective opening and closing movement of the door, it is conventionally foreseen the presence of a sliding track to which the door panel is suspended by means of convenient means. In order to allow the opening and closing movement of the door, it is usually provided that the sliding track, placed in correspondence with the upper part of the cash structure, is equipped with sliding means usually of the trolley type to which, by means of of conventional threaded means, the upper edge of the door is joined by means of suitable support and anchoring devices for the door panel.

State of the art

[0004] In the technical panorama there are many solutions of support and anchoring devices for door panels in a counter frame for sliding doors. A brief search, even if not in depth, in the field of patent literature made it possible to trace at least the following documents;

D1: JP6146726 (Yamamoto)

D2: ITF02001 A000009 (Casket)

D3: ITTV2007A000007 (De Faveri)

[0005] D1 proposes to facilitate the height adjustment of the door leaf relative to the guide rail and to prevent the possibility of loosening caused by prolonged use. The solution provides for a lever body consisting of a vertical screw joined to a threaded seat with a mounting seat mounted on the surface of the upper edge of the door panel. A suspension and support means, of the sliding type, is placed on the sliding track and is connected to the upper part of the screw rod of the lever body, which is allowed to rotate around an axis. A locking seat is obtained in the terminal part of a through hole through which the said rod of the suspension and support means is inserted. Furthermore, a protruding locking means of the type which can be engaged and disengaged from a locking seat is obtained in correspondence with the upper part of the end of said rod. The length of the threaded lever body, placed between the suspension and support element and the door leaf, is expected to be adjusted by turning the screw of the lever body so that the aforementioned locking means protrudes during the assembly of the door panel results to be released from said locking seat, to then be subsequently constrained to said locking seat.

[0006] In D2 the upper edge of the door panel provides suitable seats, placed in correspondence with each of the two lateral ends of the aforementioned upper edge itself. Inside each seat is provided for the positioning of a support device comprising a guide, consisting of a metal profile with a section in the form of a â € œCâ € and provided with holes for the engagement of threaded fastening means by means of the which last is obtained the anchoring of each guide to the corresponding seat of the door panel. Two metal wedges with 45 ° oblique cut are positioned inside the aforementioned guide, mutually engaged by means of a threaded fastening means, where the reciprocal tightening by means of the aforementioned threaded fastening means itself, forces them to offset towards two opposite sides of said guide and thus blocking the whole. One of the two wedges is expected to be equipped with an orthogonally through hole for the engagement of a threaded pin of the type equipped with a head designed to be screwed onto the corresponding threaded seat with which the sliding carriage supporting the panel is provided. leads to the guide rail.

[0007] Also in D3 an improved support and anchoring device for sliding doors is described. More specifically, it consists of a guide profile with a â € œCâ € section, provided with at least one through hole for the engagement of the same to the upper edge of the leaf of a sliding door and further provided, in correspondence of at least one side wall, of at least one seat for a tooth which is provided with at least one movable lever, equipped with a spring, which is part of a pin-holder block comprising a shaped body equipped with at least one retaining pin for the movable lever and at least one through hole for a threaded pin of the type provided with a head.

Drawbacks

[0008] Although the technique evolves, in the applicant's opinion, the current known solutions of support and anchoring devices for door panels in a counter frame for sliding doors still have limitations.

[0009] A first limitation that has not currently found a solution in the technical panorama of support and anchoring devices for sliding doors, consists in the difficulty of positioning and subsequent locking of the pin-holder device inside the guide profile. In particular, it is the applicant's opinion that the positioning of the device, for example that described in D2 due to the fact that it is substantially composed of two wedges which are in a loose condition during the introduction phase, is complex and particularly difficult requiring a quote. manual alignment. In the same way, the same drawback seems to occur in the solution shown in D3 forsâ € ™ even to a greater extent due to the fact that the spring lever present in the lower part would constitute a further obstacle to the linear introduction of the device thus configured.

[001 0] A second limitation involving the current solutions of support and anchoring devices for sliding doors, also relates to the difficulty they present in order to subsequently remove the pin-holder device from the guide profile. In other words, both in the solution described in D2 and D3, it is necessary to act in correspondence with a screw, to determine the locking, in a position of difficult access, rotating several times in an uncomfortable way, and to the extent that the sufficient loosening of the wedge or lever restraint devices which cause the locking of the device.

[00Î] A third limitation consists in the difficulty of obtaining an optimal support for the sliding door, avoiding the inconvenience that the loosening of the pin-holder device can cause an unwanted slipping of the same inside the guide profile with inevitable negative repercussions with regard to the stability of the corresponding leaf of the sliding door, circumstances which contribute to making the movement of said door panel particularly noisy.

[001 2] In relation to what has been considered, the need emerges to identify alternative and more functional solutions than the current ones.

[001 3] The purpose of the present invention is to provide a suspension support and anchoring device for the door panel in a counterframe for sliding doors through which it is possible to improve the positioning and removal of the pin holder device in the Hâ € ™ within the guiding profile, at the same time optimizing the anchoring and support conditions.

Brief description of the invention

[001 4] This and other purposes are achieved with the present innovation according to the characteristics of the annexed claims, solving the problems set forth by means of a support and anchoring device (10) in suspension, of the door panel (20) in a counter frame for sliding doors, which consists of a mechanical coupling obtained by means of a mobile tooth (130, 140} of protruding fixing which, pivoted on a body (1 10) that slides inside a metal profile (100) and dropped by unscrewing a threaded dowel (1 50) that supports it is inserted into a slot (101) obtained in the fixed profile (100) to be subsequently blocked by the same threaded dowel (1 50) which prevents it from coming out of said slot (101).

Aims

[001 5] In this way, some advantageous objectives are achieved through the appreciable creative contribution whose effect constitutes immediate technical progress.

[001 6] A first advantageous object consists in realizing a support and anchoring device for the door panel which ensures a highly resistant locking against accidental sliding, due to energetic impacts of the door panel at the end of the stroke and does not require safety checks. tightening due to a possible loosening of the locking caused by vibrations, transmitted by the normal sliding of the door panel, at the same time ensuring optimal anchoring and support of the door panel, facilitating the operations necessary for positioning and removing the pin-holder block from the € ™ inside of the guide profile.

[001 7] A second advantageous object consists in realizing an improved support and anchoring device for sliding doors in which the position of the pin-holding block within the guiding profile can be predetermined.

[001 8] Another advantageous object is to provide an improved support and anchoring device for sliding doors through which it is possible to reduce the installation times of the same, consequently helping to contain the costs associated with such an operation . In particular, the introduction phase of the mobile bracket inside the fixed bracket is made more comfortable, and at the same time the removal phase is easier, without the need to pay particular attention in alignment, since the bracket mobile forms a single stable body together with the lever which integrates the hooking tooth.

Practical example of realization

[0020] The support and anchoring device in suspension (10) of the door panel (20) (Fig. 1), in a counter frame for sliding doors, is substantially constituted by a fixed guide bracket (100), a bracket body mobile (1 10) of substantially square section, an adjustment screw (120) and connection to the sliding carriage along the track which adjustment screw (120) is substantially perpendicular and passing with respect to said mobile bracket (1 10), a lever (1 30) with hooking tooth (140) where the said lever is pivoted with respect to the mobile bracket (1 10), a dowel (1 50) which is screwed in correspondence with the front head (1 1 1) in at least one of the two threaded seats (1 1 2, 1 1 3) each passing through the said front head (1 1 1) of the mobile bracket (1 10) so as to communicate with the niche (1 14) for housing the said lever (1 30) with hooking tooth (140).

[0021] The support and anchoring device in suspension (10) is designed to allow the anchoring of a door panel (20) of a sliding door and for the connection and fixing of the sliding carriages along the joined track to the crossbar, in a counter frame for sliding door to the door panel (20), as close as possible to the track of the counter frame itself, thus leaving as little space as possible between the track and the door panel (20) and consequently without using normal brackets support, screwed along the upper side of the door panel (20) which protrudes from the overall perimeter of the panel itself.

[0022] The support and anchoring device in suspension (10) consists of a mechanical coupling obtained by means of a coupling tooth (140) which protrudes with respect to the mobile bracket (1 10) and which, once pivoted on the body of the said movable bracket (1 10) by means of the lever (1 30) it is able to swing from a locking position, Figure 9, to a release position Figure 6 with respect to the fixed guide bracket (100). More in detail, the movable bracket (1 10) in an installation phase, slides inside the fixed guide bracket (100), which is made up of a metal profile with a â € œC "section, so that the lever (130) dropped by unscrewing the threaded dowel (1 50) from the seat (1 13), causes the relative tooth (140) to be inserted in at least one slot (101) (Fig. 9) which is obtained in correspondence with the bottom (102) of the fixed guide bracket (100). In this condition the lever (130) with the hooking tooth (140) is then blocked by the same threaded dowel (1 50) which prevents it from being coming out of this slot (101), moving the said threaded dowel (1 50) in the appropriate upper threaded seat (1 1 2). The insertion of the mobile bracket body (1 10) along the fixed guide bracket body ( 100) can also be done with the dowel (1 50) already unscrewed and removed from the seat (1 1 3), by simply pushing the mobile bracket body (1 10 ) inside the longitudinal housing in the fixed guide bracket (100).

[0023] As regards the lever (130) (Fig. 5) it consists of a monolithic body, housed inside the niche (1 14) which is obtained along the base side of the mobile bracket (1 10) facing the bottom (102) of the underlying fixed guide bracket (100). Said lever (130) is pivoted with one end inside the niche (1 14) and with respect to the mobile bracket (1 10) in such a way that its oscillation allows the front end (1 31) of the lever ( 130), opposite to the pivoting one, which is provided with a hooking tooth (140) that protrudes with respect to said niche (1 14) to enter the underlying fixed guide bracket (100) to the inside the slot (101). More specifically, the front end (131) of the lever (130) includes the coupling tooth (140) which faces the underlying fixed guide bracket (100) while the head side (134) of the lever (130 ) against which the screw grain (1 50) insists includes two inclined planes (1 32, 1 33) oriented in the opposite direction (Fig. 6), against each of which, depending on the required operation, the said grain insists screw (150) in such a way that in correspondence with the lower inclined plane (1 32) the lever (130) and the relative hooking tooth (140) are raised, while varying the position of said screw nut (1 50) ) moving it from the lower threaded seat (1 13) to the inside of the upper seat (1 12), progressively insists in correspondence with the upper inclined plane (1 33) so as to push the lever (1 30) with the tooth coupling (140) beyond the edge of said niche (1 14) to ensure that said coupling tooth ( 140) is introduced inside the slot (101) of the underlying fixed guide bracket (1 00). In this position, the front end of the lever (131) with the locking seat (135) of the dowel (1 50) is almost aligned with the upper threaded seat (1 12) in such a way as to allow the dowel (150) in a screwed condition determines, by overlapping the said locking seat (135) of the dowel (150), the stop of the oscillation movement of said lever (130).

[0024] Operationally, when inserting the movable bracket body (1 10) into the fixed guide bracket (100), the threaded dowel (1 50) keeps the lever (130) with hooking tooth (140) raised, which is pivoted through the metal pin to the movable bracket body (1 10). Once in the locking position, which can be predetermined, for example by a stop for the mobile bracket body (1 10), the threaded dowel (1 50) is unscrewed from the said lower perforated and threaded seat (1 1 3) which is ̈ at the head of the movable bracket body (1 10). In this way the lever (130) with the hooking tooth (140) rotates downwards and the hooking tooth (140) is positioned inside the slit or slot (101) on the bottom (102) of the bracket fixed guide (100). At this point the threaded dowel (150) is screwed in order to lock the lever (130) and the hooking tooth (140) in the closed position.
