Description

The design relates to the furniture industry, in particular to tables that can be transformed into a position that increases the area of the countertop by extending into the middle of the intermediate countertop, the middle part of which in the folded position remains horizontal, so it can be used as a cache. Applicable for coffee, kitchen and dining tables.

There are various kinds of sliding or folding tables with an increase in the area of the countertop. For example, a folding dining table containing a base consisting of legs attached to the frame, a countertop consisting of two equal parts interconnected by piano loops, and a mechanism for turning the tabletop in a horizontal plane 90 degrees when unfolding (see manufactured by Elegia LLC ", Borovichi, Russia, Novgorod region, Folding dining table, TO 532001-3079-13-99). Despite the simplicity of the design of the table, it is not very stable, since each part of the tabletop in the unfolded form rests on 1/2 of the base. In addition, all folding manipulations are carried out manually.

Closest to the claimed combination of essential features is a transforming table containing a base consisting of interconnected support elements that perform the function of legs (actually a frame and legs), a tabletop that is folding from two equal parts, two mechanisms for raising and lowering the tabletops located mirror-like in relation to each other, with each mechanism made in the form of a pivot-lever parallelogram, the parallel levers of which in the lower part are pivotally mounted on a carrier plate, in its a turn, fixed to the base of the table, and in the upper part they are fixed to the corners, on the horizontal shelf of which there is a support platform for installing the hinged part of the tabletop, and one of the levers for lifting the tabletop through the connecting rod and rod is pivotally connected to one of the levers for lifting the base platform above swing of the support arm of the countertop (see patent of the Russian Federation 81625 of 11/7/2008, patent holder of LLC Furniture company Grand).

In a well-known table, the tabletop and the supporting platform for installing the second half of the tabletop are automatically raised using the articulated parallelogram mechanism from the “coffee table” position to the “dining table” level, and then the second part of the tabletop is manually laid out like a book on the supporting platform. A disadvantage of the known table is partial automation - the rise is automated, but not the folding tabletops. In the "dining table" position, the design will be rather "flimsy", since it is difficult to ensure sufficient rigidity with such large levers. In addition, a well-known table (as well as an analogue table) is transformed with the overturning of a part of the countertop, which does not allow creating a “cache” in this table.

The task is to increase the reliability of transformation, the degree of automation and expansion of functionality.

The technical result is achieved by increasing the rigidity of the structure and the possibility of the device "cache" in the folded position.

This object is achieved in that the transformer table containing the frame with legs, two equal countertops and two transformation mechanisms for each countertop, arranged mirror-to-one relative to each other and made in the form of an articulated-lever parallelogram mechanism connected to the countertop in the upper part, according to the invention contains an intermediate tabletop, consisting of a middle and two side parts, pivotally connected to the middle part, and with a frame using levers, each articulated parallelogram The main mechanism is supplemented by a second similar mechanism, rigidly connected to the first at an angle, forming a double hinged-lever parallelogram mechanism, which in the lower part is pivotally connected to the side part of the slider formed by a rigid connection with the middle part of the side parts of both mirror mechanisms, the slider is connected by guides with the possibility of sliding in them with the middle part of the intermediate countertops, which are rigidly connected to the rails.

The task is also achieved by the fact that in the transformer table the angle of the levers of the double articulated lever parallelogram mechanisms is (90 ± 10) degrees.

The task is also achieved by the fact that in the transformer table, the levers of the table most distant from the table center of the mirror-mounted articulated parallelogram linkage mechanisms are rigidly connected to each other.

The task is also achieved by the fact that the transformer table is equipped with a servo drive, consisting of at least one spring attached to the middle part of the slide mechanisms of the transformation mechanisms of both countertops.

On Fig shows a diagram of the folding middle part of the table.

The proposed table (Figs. 1-8) contains a frame 1, on which legs 2 are fixed, two equal countertops 3, an intermediate countertop made of middle 4 and two side 5 parts connected to the middle part 4 by a hinge (piano loop), and frame 1 - with the help of U-shaped levers 6 (Fig. 8), two double hinged-lever parallelogram transformation mechanisms for each countertop, which are located mirror-image with respect to each other, connected in a single mechanism for each countertop 3 (Fig. 3). Each double hinged-lever parallelogram mechanism contains a L-shaped bracket 7 rigidly connected to the tabletop, which at points B is pivotally connected to triangular levers 8, which, in turn, are pivotally connected at points C to part 9, which is part of the frame 1. The first parallelogram mechanism formed by the bracket 7, the arms of the arms of the levers 8 and the housing 1, provides movement along the arc of a circle of the countertop 3 (in the unfolded or folded position). The second parallelogram mechanism, formed by part 10, the arms of the SD arms of the levers 8 and the frame 1, provides vertical movement of the middle part 4 of the intermediate countertops while maintaining its horizontal position (translational movement). The two parallelogram mechanisms are doubled by a rigid connection of the arms of the BC and the SD of the levers 8, which ensures reliable operation when the levers 8 are turned by approximately 190 (180 + 10) degrees. Details 10 of each mechanism for transforming countertops 3 are interconnected by part 11, and together they form a slider that is connected to the middle part 4 by guides 12 (Fig. 8) with the possibility of sliding in them. The guides 12 are rigidly connected to the middle part 4. Part 13 connects two triangular levers 8 to ensure synchronization of the mechanism of transformation of the tabletop 3 along the sides. To reduce the effort of raising and lowering the countertops 3, the transformer table is equipped with a servo drive, consisting of at least one spring 14, attached to the parts 11 of the sliders of both countertops 3.

The folding process (Fig.5-7) is as follows. Being on the side of the central part of the table, we apply a small force to the countertops 3 in the direction of elevation. During the lifting of the countertops 3, the first parallelogram mechanism (bracket 7 - the arm of the BC - frame 1) comes into effect, turning the levers 8 relative to points C. The countertops 3 rise along an arc of a circle, making room for an intermediate countertop. At the same time as the first one, the second parallelogram mechanism comes into action (part 10 — SD arm — frame 1), turning the lever 8 relative to point D. Upon completion of the rotation of the levers 8 by approximately 190 degrees, the guides 12 from the lowermost position in FIG. 5 go through the intermediate position Fig.6 to its highest position in Fig.7, while causing the middle part 4 of the intermediate countertop to rise. With the translational movement of the middle part 4 during folding, the levers 6 rotate the side parts 5 to a horizontal position. An intermediate countertop 4, 5 is automatically placed on the frame 1, next to which countertops 3 are laid under its own weight. This completes the transformation to the unfolded position. Folding is as follows. Since the guides 12 grasp the slider from the sides and from the bottom, then when lifting the tabletops 3 upwards, the slider in the guides 12 "drags" the middle part 4 behind it and lowers it to the lowermost position. Everything else happens in reverse order. The operation of the servo is visible in figure 5-7. In Fig.6, countertops 3 are in the upper position. In this case, the spring 14 is completely relaxed. When unfolding to the position of Fig.7 and folding to the position of Fig.5, the spring 14 is stretched, softening the lowering of the countertops 3 or facilitating their lifting.

Compared with the prototype of the inventive transforming table has the following advantages:

- Creation of additional seats;

- at all stages of transformation: lifting, folding, folding and vice versa - fully automated;

- thanks to the double rigid joints at an angle (90 ± 10) degrees of two articulated lever parallelogram mechanisms, an easy and reliable transformation is ensured;

- Rigid table construction in the unfolded position;

- the rigid and reliable design allows the use of a cheaper and more technologically advanced material, such as plastic, for the transformation mechanism;

- the middle part of the intermediate countertop, performing translational motion during transformation, always maintains a horizontal position, which made it possible to arrange a "cache" in the table in the folded position.
