Description

DESCRIPTION

"ANTI-DEVELOPMENT INSURANCE FOR SLIDING DOORS"

FIELD OF THE INVENTION

This invention concerns an anti-derailment insurance 5 for sliding doors, particularly an anti-derailment insurance of those used in furniture sliding carriages, to prevent the derailment of said sliding cars on the rails linked to a sliding door.

10 STATE OF THE PREVIOUS TECHNIQUE

At present and as a reference to the state of the art, the use of anti-derailment insurance for sliding doors is common and known, to avoid derailment in the lower rail of the sliding carriages of the interior doors or of the external door of an item of furniture.

There are different solutions present in the market that have the following drawbacks.

Many of the anti-derailment locks for sliding doors consist of a support or housing that is incorporated into the wheel that slides along the lower rail arranged for it, and said support or housing contains pins or nails with counter-outputs that fit into the rail and prevent the wheel from leaving. However, these pads do not usually have sufficient rigidity, and in the face of sudden blows, or because some element obstructs the sliding of the wheel on the rail, the door is capable of abandoning its position and derailing.

On the other hand, some of the anti-derailment security systems for sliding doors are characterized by incorporating said anti-derailment insurance in the component that is fixed to the sliding door, or integrated therein, so that in case of failure of the device of sliding that incorporates the security system, it is necessary to replace the whole set, also having to disassemble the door.

Faced with this state of affairs, the present invention refers to an anti-derailment insurance for sliding doors, in particular for sliding carriages located on sliding doors, mainly in the lower rail, in which the wheel support has at least one of its sides, an extension in flexible pins with a harpoon tip and a sliding plate with its respective lateral prominence, a sliding plate which, when placed in an advanced position, does not allow flexion of the extension in flexible pins, ensuring its position between the rail heads .

Thanks to this configuration, once the extensions in flexible pins are introduced in the lower rail to prevent the derailment of the wheel, due to the harpoon tip that they have that is linked to the railhead stops in case of pitching of the door, acting on the lateral prominence of the drive that emerges from the sliding plate to place it in an advanced position, said sliding plate is housed between the extensions in flexible pins, so that it stiffens and prevents them from easily bending. In this way, in the event of any incident that may cause the pitching or derailment of the sliding carriage, the stiffness of the extensions in flexible pins will be greater, being able to withstand greater forces and increasing the security against the overturning of the sliding door.

Another feature of the invention is that preferably the position of the harpoon tip of the flexible pins is close to each other, which can be separated by moving the sliding plate between them.

Thanks to this configuration of the extensions in flexible pins, the introduction of the pins in the rail avoids having to force the pins at the time of their introduction and thus preventing breakage, providing greater durability. In addition, the friction of the harpoon tip with the rail head stop is avoided since it is fitted between the harpoon tip and the projection of the wheel support thanks to its configuration adapted to the profile of the

rail.

Another feature of the invention is that the wheel support has at least one of its sides, a guide channel that houses the sliding plate.

Thanks to this configuration, it is possible that the sliding plate reaches the desired position between the extension in flexible pins, and thus be able to increase its stiffness against flexion.

Another feature of the invention is that in a preferred embodiment, the wheel support has both an extension on flexible pins and a sliding plate on both sides.

Thanks to this configuration of the wheel support, in which the existence of extensions in flexible pins and sliding plates occurs on both sides of the wheel support, greater safety is achieved against possible derailment and greater prevention of overturning the door.

EXHIBITION OF A PREFERRED EMBODIMENT

With regard to the drawings and references listed above, a preferred embodiment of the object of the invention is illustrated in the attached drawings, referring to an anti-derailment insurance for sliding doors, in particular for sliding cars located on sliding doors, in which the wheel support (3) has at least one of its sides, an extension in flexible pins (4) with a harpoon tip (5) and a sliding plate (7) with its respective lateral drive prominence (8), sliding plate (7) which, when placed in an advanced position, does not allow flexion of the extension in flexible pins (4), ensuring its position between the rail heads (14).

Figure 1 shows an exploded isometric view of the sliding carriage (1), formed by a door fixing housing (2), a wheel support (3), two sliding plates (7), a wheel (9 ) and a wheel axle (11). As shown in figure 2, said sliding carriage (1) is installed in the lower part of the sliding door (13), by means of screws that fix the fixing housing to the door (2) that contains the rest of the elements, leaving the wheel (9) with its rolling surface (10) on the rail heads (14).

As can be seen in figures 3a and 3b, the extensions in flexible pins (4) emerging from the bottom of the support of

Wheel (3) are housed in the lower rail (12). The harpoon tip (5) of said extensions on flexible pins (4) is inside the lower rail (12) in a normally closed situation, and the rail heads (14) are designed so that they incorporate about 5 head stops. rail (15) that link to the harpoon tip

(5) to prevent the sliding carriage (1) from leaving the lower rail

(12) once said harpoon tip is opened. In the event of sudden knocks on the sliding door (13) or the introduction of any element in the lower rail (12), it is possible that the door heads and the carriage

10 sliding (1) may leave its position, causing derailment of the sliding door (13). With the purpose of opening and stiffening said extensions on flexible pins (4) and ensuring that they do not leave the lower rail (12) in the face of said blows, by sliding down the lateral drive prominence (8) 15 that emerges from the sliding plate ( 7) and place it in an advanced position, this sliding plate (7) is housed between the extensions in flexible pins (4) due to the guide channel (6) existing on the sides of the wheel support (3), guide channel

(6) which houses the sliding plate (7) and extends to said extensions in flexible pins (4). In this way, it

increases the stiffness of the extensions in flexible pins (4) and the resistance against sudden blows or undesirable elements that are introduced in the lower rail (12) that can cause the pitching of the sliding door (13) and its subsequent derailment.

It should be noted that in a preferred mode of execution, it is provided that from the wheel support (3) the extensions in flexible pins (4) on both sides emerge for greater stability and safety against a possible derailment of the slide car (1) and preventing the overturning of the sliding door

(13).

Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essentiality of this Patent.
