Description

Safety self-closing device for sliding furniture doors.

Field of the Invention

This invention concerns a device that It is intended to be applied to sliding furniture doors, in particular for sliding door systems that are consisting of at least one internal sliding door and a external sliding door, which are moved by rolling assemblies that are installed on their bottom edge and that on their upper edge they have some means of railing, there are also closing sets (self-closing) that are equipped with fluid dampers and that interact with media traveling in the sliding doors to give them a final boost to ensure its closure when they are close to their travel stop, while opposing a brake action that prevents it from occurring hit on this travel stop.

Prior art

In sliding door systems with self-closing devices are given problems of pitching of the doors that, not only cause bad image of the product, of a sliding with rattle that is annoying and produces blows; if not which can also be the cause of door derailments and of the appearance and progressive increase of clearances. The reason for this is the efforts to which the door is subjected in the closing and at the opening, in confluence with the available vertical space in the upper and lower track of the same and in conjunction also with the width of the door (which, for some same conditions of the rest of the parameters, influences the greater or smaller amplitude of the unwanted pitch); in closing the self-closing damper brakes the door at the top where the hook and inertia of the door tends to pitch raising the door at the same top angle where it has produced the closing of the self-closing and, consequently braking. In the opening the pitch is produced because the door is hooked at the top by the self-closing mechanism and the force with the one that we intend to open is applied in the vertical zone half of a door edge that being distanced from the hitch upper self-closing that holds it makes the pitching produce by raising the door in the upper corner opposite the retained by self closing.

Explanation of the invention and advantages

In the face of this state of affairs, the present invention aims at a self-closing device that incorporates means intended to avoid the pitching problem and which, as mentioned, is designed in particular for sliding door systems formed by at least an internal sliding door and an external sliding door that move by means of rolling assemblies that are installed on its lower edge and that on its upper edge have incarcerating means, there are also closing assemblies (self-closing) provided with fluid dampers and that interact with means that travel in the sliding doors to give them a final impulse that ensures their closure when they are close to their travel stop, while opposing a brake action that prevents a stroke in this travel stop. To this end, this advocated device consists in that said means that carry the upper edge of said inner and outer sliding doors comprise: a rail that is fixed to the furniture and that for each of the sliding doors has a channel with a general "U" shape. "inverted; two brackets fixed in relation to the ends of the sliding doors and each of them providing a plate that is on the edge of the sliding door; a pair of horizontal wheels that are installed on each plate, aligned transversely to the sliding door movement, equipped with an independent and insane rotation and which at its periphery are embraced by the vertical sides of its corresponding gutter; an armor that emerges in each plate and that, towards one side of the sliding doors, this armor incorporates a vertical guide in which it is possible to slide a carriage that screws in an axially fixed screw and that has a vertical wheel installed that protrudes by on top of this car, while, on the opposite side of the sliding doors, this armor forms a breast that is delimited between two vertical walls and that, the whole of the breast and the vertical walls, operate in conjunction with a tilting hook of said set of
closing.

With this recommended constitution it is possible, and this is done, move the carriage carrying the vertical wheel to along its vertical guide until there is a convenient clearance between this vertical wheel and the roof of the "U" gutter inverted (from the rail fixed to the furniture), just enough for the wheel vertical does not roll while the horizontal wheels; how in addition this vertical wheel device with regulation of its height position is installed in relation to both ends of each sliding door, there are no clearances capable of producing the unwanted nod, only the minimum ones to prevent the vertical wheels are in permanent contact with the roof of your gutter and that are not by far enough to produce a nodding appreciable or, much less, harmful to the effects here considered.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, referred to a device of safety self-closing for sliding furniture doors, in particularly for sliding door systems formed by, at less, an interior sliding door (1) and a sliding door exterior (2) that are moved by rolling assemblies that are installed at its lower edge and at its upper edge have of means on track, there are also closure sets (self-closing) (3) that are equipped with fluid dampers and that interact with means that travel in the sliding doors to give them a final boost that ensures their closure when they are close to their travel stop, while opposing an action of brake that prevents the bump in this travel stop. From the following exposure follows that the invention is applicable to any sliding door system whatever the number of these; however, for simplicity and for being exceedingly clarifier for the perfect understanding of the invention, the drawings they refer to the case, on the other hand very common, of a system of two sliding doors (1, 2).

As clearly illustrated in Figure 1, this device of the invention offers a peculiar constitution wherein said upper edge means of said said interior (1) and exterior (2) sliding doors comprise: a lane (4) that is fixed to the furniture (5) and that for each of the Sliding doors presents a gutter (6) with general shape in Inverted "U"; two supports (7) fixed in relation to the ends of the sliding doors (1, 2) and each one of them providing a plate (8) that is on the edge of the door sliding (1, 2); a pair of horizontal wheels (9) that are installed on each plate (8), aligned transversely to the sliding sliding doors (1, 2), equipped with turning crazy and independent and that on their periphery are embraced by vertical sides (10) of its corresponding gutter (6); a armor (11) that emerges on each plate (8) and that, to one side of the sliding doors, this armor (11) incorporates a guide vertical (12) in which it is likely to slide a car (13) that screws in an axially fixed screw (14) and that has installed a vertical wheel (15) protruding above it carriage (13), while on the opposite side of the doors sliding (1, 2), this armor (11) forms a breast (16) that is delimited between two vertical walls (17) and that, the whole of the sinus (16) and vertical walls (17), operate in conjunction with a tilting hook (18) of said closure assembly (3). How I know see in figure 1, the plate (8) is the horizontal wing of a squad that has its vertical wing tied to the back of the door sliding (1, 2). Also in figure 1 a box (23) is shown which is formed inside the gutters (6) for the installation of the autocierres (3).

The functionality of the invention is simple effective. and reliable. Once the sliding door (1, 2), with its two devices at their ends (figure 5), has been on track, these devices are left as shown in the figures 1 and 6 that are given transversely to the displacement of the same: the horizontal wheels (9) roll on the sides vertical (10) of its channel (6) in the rail (4), determining a perfect and smooth guidance of said longitudinal displacement; then, acting on the screw (14), the carriage (13) in the vertical guide (12) of the frame (11) until, without contacting him, the vertical wheel (15) leaves (figure 6) a clearance (19) with respect to the roof of the gutter (6). Being correctly leveled the sliding doors (1, 2) and on their bottom edge, having each one of them a device of the invention at each end, with the realization of said regulatory operation on both vertical wheels (15) is get an adjustment on vertical track that prevents the pitching effect of the sliding door may occur (1, 2). In this regard, Figure 6 is clarifying when showing different vertical wheel adjustment positions vertical (15) in relation to their respective armor (11) what which corresponds to the case in which there are differences of measure or operating vertical position between the interior sliding doors (1) and exterior (2).

The operability of the device of the invention in relation to the self-closing (3) it is illustrated sequentially through the pairs of figures 3-4, 7-8 (with extensions 9a and 9b) and 1-2. In figures 3 and 4 the sliding door (1, 2) has not yet reached the position of the self-closing (3), so (figure 3) the tilting hook (18) is retracted, its spring tractor (20) is in tension and the rod (22) of the shock absorber fluid (21) is in its extended position. In figures 7, 8, 9a and 9b illustrates the moment of reaching the position of the self-closing (3) that starts the hitching maneuver; in figure 9a the moment at which the front vertical wall (17) is shown of the armor (11) bumps against the swinging hook (18) and does swing to the position of figure 9b in which this hook swingarm (18) is released from its retention and, by action elastic recovery of the tractor spring (20), is dragged towards the closing frame of the sliding door (1, 2) causing the rod (22) of the fluid damper (21) penetrates the body of  this one with a braking action that prevents the closure on the frame occurs with blow; the final hitch position is, precisely, the one represented in figures 1, 2 and 6.
