Abstract
Anti-derailment safety device for sliding doors, in particular for slide carriages positioned on sliding doors, wherein the wheel support (3) has, on at least one of its sides, an extension in the form of flexible pins (4) with a barbed tip (5) and a sliding shim (7) with its respective lateral actuation protrusion (8), which sliding shim (7), on being placed in a forward position, does not allow the extension in the form of flexible pins (4) to flex, securing its position between the rail heads (14).
Description
- This invention relates to an anti-derailment safety device for sliding doors, particularly an anti-derailment safety device of the type used in furniture slide carriages, to prevent the derailment of said slide carriages from the rails engaged with a sliding door.
- Currently, with reference to the prior art, it is known and common for anti-derailment safety devices to be used for sliding doors, to prevent the slide carriages of the inner doors or the outer door of a piece of furniture from being derailed from the lower rail.
- There are various solutions available on the market, which have the following drawbacks.
- Many anti-derailment safety devices for sliding doors consist of a support or housing incorporating the wheel that slides over the lower rail provided for that purpose, and said support or housing contains pins or claws with retainers that fit into the rail and prevent the wheel from leaving it. However, these pins are not usually rigid enough and, in the event of sudden impacts, or if some element impedes the sliding of the wheel over the rail, the door is likely to leave its position and become derailed.
- Furthermore, some anti-derailment safety systems for sliding doors are characterised in that they incorporate said anti-derailment safety device in the component that is fixed to the sliding door, or integrated into the latter, and therefore if the slider device incorporating the safety system is damaged, the whole assembly needs to be replaced, and the door also needs to be disassembled.
- Faced with this situation, the present invention relates to an anti-derailment safety device for sliding doors, in particular for slide carriages positioned on sliding doors, mainly on the lower rail, wherein the wheel support has, on at least one of its sides, an extension in the form of flexible pins with a barbed tip and a sliding shim with its respective lateral actuation protrusion, which sliding shim, on being placed in a forward position, does not allow the extension in the form of flexible pins to flex, securing its position between the rail heads.
- Thanks to this configuration, once the extensions in the form of flexible pins are inserted into the lower rail to prevent the wheel from derailment, because of the barbed tip that they have, which engages with the rail head stops in case the door wobbles, operation of the lateral actuation protrusion that juts out from the sliding shim so as to place the latter in the forward position causes said sliding shim to stay housed between the extensions in the form of flexible pins, making them rigid and preventing them from easily flexing. In this way, if there is any incident that might cause the slide carriage to wobble or become derailed, the extensions in the form of flexible pins will become more rigid, withstanding greater forces and increasing protection against the tipping of the sliding door.
- Another characteristic of the invention is that the position of the barbed tip of the flexible pins is preferably close together and capable of spreading apart when the sliding shim is moved between them.
- Thanks to this configuration of the extensions in the form of flexible pins, when the pins are inserted into the rail it is not necessary to force the pins in order to insert them, thus preventing breakage, which leads to greater durability. Abrasion of the barbed tip by the rail head stop is also avoided, since it remains housed between the barbed tip and the protuberance of the wheel support thanks to its configuration suited to the profile of the rail.
- Another characteristic of the invention is that the wheel support has, on at least one of its sides, a guide channel housing the sliding shim.
- This configuration allows the sliding shim to reach the desired position between the extension in the form of flexible pins, and thus to have greater rigidity against flexion.
- Another characteristic of the invention is that, in a preferred embodiment, the wheel support has both an extension in the form of flexible pins and a sliding shim on both sides.
- This configuration of the wheel support, in which there are extensions in the form of flexible pins and sliding shims on both sides of the wheel support, results in greater protection against possible derailment and better prevention of tipping of the door.
- To get a better understanding of the nature of the invention, the attached drawings illustrate an industrial embodiment solely by way of explanatory, non-restrictive example.

- In relation to the drawings and reference numerals listed above, the attached plans illustrate a preferred embodiment of the subject-matter of the invention, relating to an anti-derailment safety device for sliding doors, in particular for slide carriages positioned on sliding doors, wherein the wheel support (3) has on, at least one of its sides, an extension in the form of flexible pins (4) with a barbed tip (5) and a sliding shim (7) with its respective lateral actuation protrusion (8), which sliding shim (7), on being placed in a forward position, does not allow the extension in the form of flexible pins (4) to flex, securing its position between the rail heads (14).
-
Figure 1 shows an exploded isometric view of the slide carriage (1), formed by a housing for fixing to the door (2), a wheel support (3), two sliding shims (7), a wheel (9) and a wheel axis (11). As shown inFigure 2 , said slide carriage (1) is installed on the lower portion of the sliding door (13), by means of screws that fix the housing for fixing to the door (2), which contains the other elements, the wheel (9) and its running surface (10) remaining on the rail heads (14). - As can be seen in
Figure 3a and 3b , the extensions in the form of flexible pins (4) that jut out from the bottom of the wheel support (3) are housed in the lower rail (12). The barbed tip (5) of said extensions in the form of flexible pins (4) stays within the lower rail (12) in the normal closed situation, and the rail heads (14) are designed so that they incorporate rail head stops (15) that engage with the barbed tip (5) to prevent the slide carriage (1) from coming out of the lower rail (12) once said barbed tip opens up. If there are sudden impacts on the sliding door (13) or some element gets into the lower rail (12), the door may tip and the slide carriage (1) may come out of position, causing the sliding door (13) to be derailed. With the aim of opening said extensions in the form of flexible pins (4) and making them rigid, and ensuring that they do not come out of the lower rail (12) in the event of such impacts, when the lateral actuation protrusion (8) that juts out from the sliding shim (7) is slid downwards and put into the forward position, this sliding shim (7) remains housed between the extensions in the form of flexible pins (4) owing to the guide channel (6) present on the sides of the wheel support (3), this guide channel housing the sliding shim (7) and extending towards said extensions in the form of flexible pins (4). This results in increased rigidity of the extensions in the form of flexible pins (4) and increased resistance to sudden impacts or unwanted elements getting into the lower rail (12), which can cause the sliding door (13) to tip and subsequently become derailed. - It should be noted that a preferred embodiment provides for the extensions in the form of flexible pins (4) to jut out from both sides of the wheel support (3), for greater stability and protection against possible derailment of the slide carriage (1) and preventing the sliding door (13) from tipping.
- The essential features of this patent are not altered by variations in materials, shape, size and arrangement of the component elements, which are described non-restrictively.
