Description

A device for mounting drawers furniture.

Field of the Invention

This invention concerns a device for drawer assembly in furniture that is particularly intended for assembly of drawers that are constituted by two sides, right and left, a rear, low or high, and a floor, where the sides and the back are of folded sheet that have means of mutual engagement in their position that have means of engagement mutual in their mounting position and form two ribbed folds for insertion into them of the edges of a floor that is of wood chipboard and is tied with screws through the wall of corrugated folds.

Prior art

In the manufacture of these drawers occurs with frequency that have to be built one by one by means manuals

For example, when it comes to a small furniture manufacturer who does not want to have drawers of all possible standardized measures, but prefer to have a certain amount of laterals (right and left), of rear (high and low) and floors, to mount them in each moment according to the needs of the furniture sold. This way it does not have drawers of little requested measures stored, with the consequent financial cost and considerable space occupied by armed drawers; in return, it has stored flat elements that take up much less warehouse space and that they require less value immobilized for their versatility, since the side and rear in question are valid for the various  drawer widths, which will be determined by the width of the floor mounted in each case. At this point, the aggravating the fact that the width of the drawer to constitute does not depend only on the outer width of the module furniture drawer, but also the thickness of the panels sides of this drawer module and the guide type used for the operational displacement of the drawer.

Also the specialist manufacturer of drawers are frequently seen in the need to serve series short that do not justify being incorporated into the lines of Automated production

In any case the construction by hand of these drawers is cumbersome, does not guarantee that the results are uniform within the tolerances of the product and it is difficult to get a correct square in the assembly of the different constituent pieces.

Explanation of the invention and advantages

Faced with this state of affairs, the present invention advocates a device for mounting drawers of the type reviewed, consisting of a frame, a fixed guide and a guide mobile, the frame has a horizontal and flat surface on the that there are some means for mooring the fixed guide in, at less, a certain position for a respective series of drawers that are intended for furniture with a concrete thickness of panel and a concrete extendable slide, as well as in this frame there is a plurality of means for mooring the guide mobile at various distances from the fixed guide corresponding to different drawer widths of the series concerned, said fixed guides and mobile they form along two lodgings that from top to bottom form a circumscribed profile of the inverted cross section of such sides and rear, housings that have back a stop and, just ahead of it, a vertical hole that allows the passage of said low or high rear.

With this simple device the maneuver of Assembling a drawer consists simply of first inserting the right and left sides in their respective housings of the fixed and mobile guides, second, insert the rear high or low until hooked by clips on the right sides and left, third, insert the floor by sliding into the breast of the corrugated folds of both right and left sides and final front penetration in the high back ribbed fold or lower, and fourth, perform the drainage of the floor of the drawer to through the outer wall of said corrugated folds.

This advocated device ensures the correct square of the structure of the drawer, as well as the due homogeneity between the successive units thus produced. Further, facilitates and streamlines the various necessary manual operations to constitute one of these drawers, since with this device each component is located and immobilized in its correct position of assembly during all the maneuver necessary for this mounting.

The device requires prior preparation of location of the fixed guide depending on the thickness of the panels sides of the furniture module where the drawer hole is, and depending on the thickness of the extendable sliding guide used For this drawer. So, the various possible positions of the mobile guide correspond to drawer widths of the same series defined by the conditioning established by the fixed guide; it will be enough to insert in each case the floor of the appropriate measure. Keeping the mobile guide in the same relative position with respect to the fixed guide will get all the drawers that are desired with the same width and with low or high back, indistinctly. Whether suddenly want to build drawers for a different series (different thickness of furniture side panels and / or different type guide) the position of the fixed guide; done this any possible position of the mobile guide in the frame will produce a different drawer width belonging to this new series.

Another object of this invention is that at least in the driving guide are incorporated driving means that act vertically and extensively between the mobile guide itself and the frame and that are applied in a place that, with respect to the guide fixed, it is further away than the one in which one's own is tied mobile guide With this you can close the distance between the ribbed folds of the right and left sides to generate a tightening in the insertion of the floor that ensures the correct  assembly in which the edges of the floor penetrate to the bottom of the corrugated folds.

These and other features of the invention they are revealed in the detailed description that follows.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings Preferred device recommended for mounting drawers which are constituted by two lateral, right (1) and left (2), a rear, low (3) or high (4), and a floor (5), where lateral (1 and 2) and the rear (3 or 4) are of folded sheet that they have mutual engagement means in their mounting position and form two corrugated folds (6) for insertion into them of the edges of a said floor (5) that is made of wood agglomerate and is fastened with screws through the wall of the folds ribbed (6).

As seen in figures 1, 5 and 6, the essence of the proposed device is that it consists of a frame (7), a fixed guide (8) and a mobile guide (9), the frame (7) has a horizontal and flat surface on which there are means for fixing the fixed guide (8) in at least one position determined for a respective series of drawers that are intended for furniture with a concrete panel thickness and a Extensible concrete slide, as in this frame (7) there is a plurality of means for mooring the mobile guide (9) to various distances of the fixed guide (8) corresponding to different drawer widths of the series concerned, said fixed guides (8) and mobile (9) form along two housings (10) that of top down form a circumscribed profile of the section Inverse transverse of such sides (1 and 2) and rear (3 and 4), housings (10) that have a stop (11) and, just ahead of it, a vertical hole (12) that allows the passage of said rear low (3) or high (4).

The use of the recommended device is illustrated by figures 1 to 4. Once the guides are located fixed (8) and mobile (9) in a certain position, proceed (figure 1) to insert the right (1) and left (2) sides in the housings (10) provided therein and so that are applied against the stops (11); then proceed to insert the rear low (3) or high (4) (except in its different height are exactly the same) until it clicks on said laterals (1, 2), with what remains a fence perfectly framed; then proceed (figures 2 and 3) to place the floor (5) by sliding into the folds ribbed (6) of the sides (1, 2) until the leading edge penetrates frontally into the ribbed fold (6) of the back (3 or 4); in this situation of figure 3, the floor (5) through the wall of the corrugated folds (6); finally, the (figure 4) open cuvette thus formed is removed to hold the right front in each case.

In the soil insertion operation (5) (Figures 2 and 3) it is interesting to ensure that the lateral edges of the same penetrate deep into the ribbed folds (6) of the lateral (1, 2). To this end, an object of the invention is that (Figures 7 and 8) at least in the mobile guide (9) are incorporated driving means that act vertically and in a manner extender between the mobile guide itself (9) and the frame (7) and that are applied in a place that, with respect to the fixed guide (8), is farther than the one in which the mobile guide itself is tied (9); the conventionally exaggerated inclination (23) of Figure 8 it translates into a displacement quite from the top of the mobile guide (9), and therefore the ribbed fold (6) of the side left (2). A preferred execution variant in this regard is that of said figures 7 and 8, wherein said driving means between the mobile guide (9) and the frame (7) consist of a mechanism of counter spring ball consisting of a cartridge (22) that is housed in the mobile guide (9) flush inferiorly with this is the mouth where the ball that is against a driving spring appears inside the cartridge (22).

This use of the advocated device requires a previous preparation explained above and that places the guide fixed (8) in a specific location for each series of drawers (function of the thickness of the furniture panel and the slide extendable used), so that the selective positions Possible mobile guide (9) determine drawer widths belonging to that series; that is, what is done with the fixed guide location (8) is to correct the width of the hole to the drawer from an outside width between the side walls that determine such a gap, depending on the thickness of these walls and of the space that must remain between them and the outer side of the drawer according to the extendable slide used.

According to the invention, the mooring means of the mobile guide (9) consist (figure 10) in that, in relation to the front and rear edges of the frame (7), this mobile guide (9) it has in extreme positions a pivot (13) and a head (14) that at its start it has an annular recess (15), said pivot (13) has a diameter that rotatably adjusts in a hole (16) of the frame (7) and said head (14) is capable of passing through of the widest part of a pear-shaped hole (17) that is extends transversely to one's own working position mobile guide (9) and which in its narrowest part has a diameter adjusted to the bottom of said annular recess (15) and its center is aligned with said hole (16) according to a parallel to said guide fixed (8); where through the head (14) a screw (20) that screws into a spline nut (19) that is embedded in the channel (10) of the mobile guide (9).

In figure 10 the representation of the guide mobile (9) corresponds to a broken conventional section that passes by the centers of the cartridge (22) and the head (14). Placement of the mobile guide (9) in the frame (7) is clearly illustrated by means of figures 11 to 15; first, the pivot (13) is inserted into its hole (16) and, at the same time, the head (14) by the wide part (figure 14) of the hole (17) and, at the same time, the head (14) by the wide part (figure 14) of the pear-shaped hole (17) (position on the left in figure 12), and then it goes on to the final position (turning to the right position in the figure 12), which achieves the situation of figure 15, where the annular recess (15) tightly receives the thickness of the frame (7) when penetrating the narrow part of said hole (17).

Another feature of the invention consists in that said fixing means of the fixed guide (8) are arranged to similarity to those of the mobile guide (9) and consist of the frame (7) has a pair of run windows (18) that are transverse to the direction of the fixed guide (8) and in which they are embedded grooved nuts (19) into which a screw screw (20) after having passed through a bushing (21), windows runs (18) whose effective amplitude comprises at least two mooring operating positions corresponding to as many series of drawers for furniture that use different thicknesses of panel and / or different types of extendable slide.

This solution is illustrated in Figure 9, and enables the necessary adjustment with firm mooring to correct the operating position of the fixed guide (8) in the frame (7), in function of various series of drawers, as already explained previously.
