Description

Guide device for sliding door or the like

The present invention relates to a guide device for a sliding door or the like as described in the foregoing section of the first application of the patent application.

A similar patent is disclosed in U.S. Patent Application Serial No. US-A-2013/160,240, the disclosure of which is incorporated herein incorporated by reference in its entirety in the entire entire entire entire entire entire entire entire entire entire entire entire portion Entrance and exit of the shower room. In particular, the device may be used to control the movement of the sliding door when the sliding door position is near or near the closed position.

As is known, sliding plates and sliding doors have been widely used, which require less space for movement than conventional plates/doors having a rotating aperture, and thereby allow for better use of available space.

The movement of the sliding door or the sliding plate is substantially by two guiding members, an upper guiding member and a lower guiding member, which allow linear movement of the door/panel and are substantially integrated with the door by a moving device. The moving device makes the movement of the door along the guide smoother and more straight.

In particular, the upper guide from the upper support door substantially supports the full load of the door itself, and typically includes a track having a closed top and sides in cross section and two sides on the underside adapted to allow for wheel and partial movement The sliding of the device, and a central opening, are adapted to allow the support pin to pass to connect the door to the device.

In addition, the sliding on the guides can be automatic or manual. In the first case, the movement of the door is controlled by a motor by means of the above-described moving device, and in the second case, the user applies force and the device ensures correct movement of the door.

In the case of manual control of movement, the mobile device that protects between the upper guide and the door is used to prevent excessive force application at the door, causing the door to collide with an external junction such as a wall or door support structure. For this reason, the mobile device has one or more support brackets integral with the door, a collision avoidance mechanism is suitable for preventing the collision, and an activation element is integrally restrained to the junction. And suitable for controlling the start of the anti-collision mechanism.

Some of the above-described guiding devices for sliding doors/sliding plates are disclosed, for example, in the patent documents IT-A-BL20060032, IT-A-BL20070014, EP-A-2050907, EP-A-0807739, DE-A-3740021 and US. -B-3294408.

The prior art described above has several major drawbacks.

In fact, when the space available for the sliding of the door is extremely limited, the guiding devices propose various difficulties in adjusting the movement of the door, which are highly related to the shower, which usually has a narrow space and the adjustments are adapted to be used. space.

Furthermore, especially in doors for plasterboard, known guiding devices can only be inserted into their interior from one end of the upper guide, because the guides and their lower surfaces are used for the two sides of the track. structure.

This disadvantage is extremely relevant to the guiding device of the sliding door that can be inserted into the recess in the wall.

In fact, in such walls, the ends of the guides cannot be accessed after the assembly steps of the walls, so the guiding devices must be inserted into the guides during the assembly step of the walls, so that they are scheduled and Predetermined.

This disadvantage makes the maintenance of the bracket (especially the dimensions required after the assembly of the wall) extremely problematic. In fact, the assembly of the wall involves the generation of dust and the like, and dust or the like may enter the inside of the guide and the guiding device to hinder the operation.

Some systems include a guide that can be removed from the wall in order to allow subsequent insertion of the guide, however such operations are extremely complex and may result in misalignment of the guide with the wall.

Moreover, conventional guiding devices are complex and expensive.

In this case, the technical object of the present invention is to propose a guiding device for a sliding door or the like which substantially overcomes the above disadvantages.

Within the scope of this technical object, an important object of the invention is to create a guiding device that can be produced in an extremely simple and cost-effective manner, even tailored to a space such as a shower in a very small space.

Within the scope of this technical object, an important object of the invention is to create a guiding device that is easy to install and maintain even when the system is assembled, especially when mounted to a wall. Protected.

Another object of the invention is to obtain a guiding device that can accurately guide a door or panel, especially at the terminal portion of its movement.

Another important object of the invention is to make a simple and inexpensive guiding device.

A technical purpose and a specific object are achieved by a guiding device for a sliding door or the like as described in the attached claim 1.

The preferred embodiments are described in the dependent claims.

The sliding system 130 may ultimately include an automatic closing member of the door, such as an elastic member, as disclosed by the inventors in the patent application No. IT-U-MI2014-000205.

The previously described guiding device 1, and also the sliding system 130 and the door 110 including the guiding device, define the following innovative assembly procedure.

In this procedure, first, if necessary, a wall 120 in a gypsum board or cabinet or other is assembled, on which the previously described guide 100 is placed.

The holder 41b or other aperture for the fastening member 44b is then preferably made by cutting the length to the desired length to define the dimensions of the device 1, and using a drill or similar tool (and possibly a plate).

The guiding device 1 is subsequently positioned in the guiding member 100, and the guiding device 1 is assembled, in particular by first inserting a single wheel of the second bracket 2b through the insertion portion 103, which is preferably The individual wheels are constructed and thus inserted into the insertion portion 103 without difficulty.

The device is then advanced along the track 101 toward the longitudinal center of the guide 100 by the second bracket 2b.

The center body is then inserted through the slit 102 and thereby inserted at any point of the guide 100 (Fig. 6).

Finally, the first bracket 2a is inserted through the insertion portion 103, preferably by a rotary hinge 46, and thereby the first bracket is inserted in an inclined position, and then straightened in the longitudinal direction 1a during insertion.

The additional bracket 131 can also be inserted through the insertion portion 103 and preferably inserted before the guiding device 1.

A limiter 132 and possibly an automatic shut-off device are then inserted. One of the limiters preferably overlaps the insertion portion 103.

Finally, the door 110 is attached by inserting the connecting member 5 (especially the restraining member 50) into the holder 111 and locking it therein.

The door 110 can thereby slide along the guide 100.

The device 1 is usually provided with a shock absorber 40 in a preloaded position, and the movable engaging element 43 is provided with a lower tooth 43c inserted into the abutment 41b, and a fastener 43d is provided in the abutment 44a.

If the device 1 is near one end and the door is brought close to a closed (or open) position, one of the upper teeth 43a (especially the one closest to the center) collides with the coupling element 104, and the lower teeth 43c are caused by the collision. The lift away from the support 41b and the fastener 43d rise away from the support 44a.

Thereby, the connecting element 104 is enclosed and closed between the upper teeth 43a, and the device 1 and the door 110 are thereby restrained on the guiding member 100, and cannot be moved unless the action of the shock absorber 40 is transmitted, whereby the shock absorber controls Speed and force move the door to prevent impact and incomplete opening and/or closing.

When the door 110 performs the reverse movement, the shock absorber 40 is reloaded to a certain point, wherein the lower teeth 43c are inserted into the holder 41b and the fastener 43d is engaged with the holder 44a by the curved guide teeth 43c made in the movable engaging member 43. in.

In this position, the door can slide freely again by the bracket 2 and the rail 101.

The movement mechanism can occur in two directions: in the first direction, the cylinder 40b is fixed and the piston 40a is moved, in the second case, and vice versa. This will achieve a mitigating impact on both opening and closing.

The present invention achieves some important advantages.

In fact, the guiding device 1 allows a custom fit, especially since the fixed section and projections are integrally formed with the shell 41, as explained above.

This solution allows tailor-made furniture and showers (usually sized according to the installation environment). The same solution may be to make the dimensions of the manufacturing device in the longitudinal direction 1a close to or equal to 4 inches.

Furthermore, even after the guide is assembled to the wall of a sliding door, the guiding device 1 may insert or remove the device in the guiding member 100.

Therefore, it is always possible to perform maintenance and the like on the assembled bracket even in the sliding door.

The fact that any maintenance operations do not affect the correct location of the device to the guide provides further advantages.

Another advantage that is equally important is that the device is easy to install, inevitably reducing installation time and reducing inaccuracies.

The present invention may be modified, and all of the elements illustrated and claimed may be replaced with equivalent elements, as well as details, materials, shapes and dimensions, without departing from the scope of the invention as set forth in the appended claims. The system can be as needed.
