Description

The utility model relates to furniture, mainly household furniture, namely to universal tables, made with the possibility of their transformation for use for different purposes, to the so-called transforming tables.

The design of tables made with the possibility of transformation from a dining table into a coffee or coffee table and vice versa is widely known. In most cases, such tables include a base with supporting elements, a countertop and a mechanism for moving the countertops in the vertical direction. The table top, as a rule, is made folding to increase its area in the position of the dining table. The differences between the designs are mainly in the implementation of the mechanism for moving the countertops. Such a table is a convenient and practical element of the interior. Without taking up much space, it can at any time be transformed from a coffee table into a full-fledged dining table.

There are known designs of universal tables in which the mechanism for moving the tabletops is made in the form of vertical guides connected to the base and movable elements installed in these guides and connected to the tabletop.

An example is a transforming table, known according to the patent of the Russian Federation for utility model No. RU 98679, IPC A47B 1/03, filing date 05/05/2010.

The table is made with a lower base plate on which supporting elements (legs) are fixed. In the supporting elements made vertical grooves. On the supporting elements (legs), a countertop rests, which is rigidly connected to two side racks. Side racks are installed in the grooves of the supporting elements with the possibility of sliding movement in these grooves.

An additional support post is fixed in the center of the lower base plate, in which the mechanism for raising and lowering the countertops is installed. The mechanism for raising and lowering the countertops can be performed, for example, in the form of a pneumatic telescopic device. The retractable element of the lifting and lowering mechanism is fixed on the lower side in the center of the countertop. A latch is installed on the support column, and on the lower (non-working) side of the countertop, a corresponding part of the latch is fixed, which interact with each other in the lower position of the countertop.

Fasteners are installed in the upper part of each pair of supporting elements, which fixes the position of the side racks relative to the supporting elements in the lowered state of the coffee table and in the raised state of the dining table. Fasteners can be made, for example, in the form of elongated rods with threaded tips and nuts (thumbs). The rods pass through the through holes in opposing support elements on each side of the table.

Changing the functional purpose of the table from the "dining table" to the "coffee table" is as follows. Unscrew the nuts on the threaded ends of the mounting rods by 2-3 turns. Then they press in the center of the table (above the mechanism for raising and lowering the countertops) until the latch actuates. Then tighten the nuts on the threaded ends.

Common features of the analogue and the proposed solution are: a transforming table, including a base with supporting elements, a countertop and a vertical movement mechanism for the countertop.

When moving the tabletop up or down from one functional position to another, jamming of the side posts in the grooves of the supporting elements is possible. To prevent this jamming, special lifting mechanisms are used (for example, the movement mechanism includes at least one screw with at least one nut - patent RU 12321324; means for changing the height of the countertops are made in the form of flexible connections with blocks associated with the drive - patent RU 2290853; the lifting mechanism includes a manual worm drive - patent RU 11663), which complicates the design, makes it bulky.

Known designs of tables-transformers, in which the tabletop is moved in the vertical direction using articulated link mechanisms.

So, the transforming table is known according to the patent of the Russian Federation for utility model No. RU 81625, IPC A47B 1/03, the filing date of the application is November 7, 2008, which includes a base consisting of interconnected supporting elements that serve as legs, a folding tabletop, two the mechanism for raising and lowering the countertops, located mirror-image in relation to each other. Each of the mechanisms for raising and lowering the countertops is made in the form of a pivot-lever parallelogram, the supporting levers of which in their lower part are pivotally fixed to the carrier plate, which in turn is attached to the base. In the upper part, the support arms are pivotally fixed to the corners, forming parallelograms. On the horizontal shelves of the corners, a folding tabletop and a supporting platform for stopping the hinged part of the tabletop are installed. A connecting rod is rigidly attached to one of the levers for raising and lowering the support platform, which is articulated at its end to the end of the rod, the second end of which is pivotally connected to one of the table top support levers.

The table is transformed as follows.

To bring the table into the “dining table” position, the countertop is raised up parallel to the base in a stable position. Then the countertop is opened in the form of a book, rotating 180 degrees.

To bring the table into the "coffee table" position, all actions are performed in the reverse order. The tabletop is lowered onto the base and folded into the “coffee table” position

Common features of the analogue and the claimed solution are: a transforming table, including a base with supporting elements, a countertop, a mechanism for moving the countertop to the "coffee / dining table" position, made in the form of a pivot-lever mechanism.

The implementation of the mechanism for moving the tabletop in the vertical direction in the form of two articulated lever parallelograms interconnected by means of a connecting rod and traction, significantly complicates the design of the table.

As a prototype of the selected transforming table "Acrobat", known according to the patent of Ukraine for utility model No. 71054, IPC A47B 1/00, application filing date 02.29.2012.

Transforming table “Acrobat” includes a lower tsar belt (base), which interconnects supporting elements that perform the function of legs, an upper tsar belt, on which the main and additional tabletops are fixed, and a mechanism for raising and lowering the main tabletop, made as an articulated lever scissors type mechanism in the form of two levers that intersect and are interconnected by a rotary axis at the intersection. The lower end of one of these levers is pivotally connected to the lower tsar belt, and its upper end is mounted with the possibility of movement in guides made in the upper tsar belt. The upper end of the second lever is pivotally connected to the upper tsar belt, and its lower end is mounted with the possibility of movement in guides made in the lower tsar belt. The lower ends of these levers are interconnected by springs, which allows you to compensate for the weight of the countertop. The fixation of the discrete positions of the main tabletop in height is provided by the mechanism for fixing the position of the ends of these levers in the guides made in the upper and lower collet belt.

When raising or lowering the main tabletop, the ends of the levers pivotally connected to the upper and lower collet belt remain in place, rotating in hinges, and the opposite ends of the levers move in the guides of the lower and upper collet belt, providing parallel lifting or lowering of the main tabletop.

Additional countertops are connected to the main tabletop using furniture hinges, which makes it possible to tilt additional tabletops at an angle of 0-90 degrees relative to the main tabletop.

The table is transformed as follows.

To bring the table into the “dining table” position, the main tabletop is lifted up until it is fixed in the desired height position, then additional tabletops are lifted up until it is locked in a horizontal position.

To bring the table to the “coffee table” position, all actions are performed in the reverse order. Additional countertops are placed in an upright position. To lower the main countertop, the mechanism for fixing the height of the main countertop is turned off, the main countertop is lowered down to the stop of the upper collet belt in the lower one. The result of this transformation is a decrease in the height of the table and the area of the countertop, which corresponds to the position of the “coffee table”.

Common features of the prototype and the proposed solution are: a transforming table, including a lower drawer belt with supporting elements, a top drawer belt with a worktop installed on it, a mechanism for moving the upper drawer belt to the "coffee / dining table" position, made in the form of a hinged-lever mechanism such as scissors, and a mechanism for fixing the position of the table.

The design of the transformer table, selected as a prototype, is not sufficiently stable in the “dining table” position, since the tabletop with the upper clerical belt is only held by the ends of two levers in this position, which requires reinforced guides to prevent the tabletop from tipping over if its load is uneven. In the "coffee table" position, these guides do not work (they are ballast), since in the "coffee table" position, the table top rests on the perimeter of the lower collet belt. This is the imperfection of the design.

The utility model is based on the task of improving the transformer table, in which, due to the constructive performance, the stability of the table in the “dining table” position is increased.

The problem is solved by the fact that in the transformer table, including the lower tsar belt with supporting elements, the upper tsar belt with a tabletop mounted on it, the mechanism for moving the upper tsar belt to the "coffee / dining table" position, made in the form of a pivot-lever mechanism of the type scissors, and the mechanism for fixing the position of the table, in accordance with the utility model, the movement mechanism is made in the form of frames, each of which is formed by two levers connected to the frame by crossbars, the levers of the frames of the cross are connected and pivotally connected to form a pivot-lever mechanism such as scissors, the ends of the levers on one side of the mechanism are pivotally connected to the upper and lower collet belts, respectively, and the opposite ends of the levers are installed in the corresponding guide grooves made in the upper and lower collet belts, with the possibility of movement along the grooves.

These features are essential features of a utility model.

It is advisable to fix the locking mechanism in the form of a stop, which is pivotally connected either to one of the drawer belts or to the levers of one of the frames with the possibility of supporting one of the frames in one of the cross members in the “dining table” position. This embodiment provides simple means to securely fix the countertop in the “dining table” position.

It is advisable to connect the levers of the movement mechanism to each other with a damper mechanism, for example, a shock absorber, which ensures smooth transition of the table from one position of the table to another.

It is also advisable to perform the table with a balancing mechanism in the form of tensile springs that connect the ends of the levers installed in the guide grooves of one of the drawer belts with the same drawer belt, which makes it easy to transfer the table from one position of the table to another.

The essential features of the utility model are in a causal relationship with the result achieved.

Thus, the distinguishing features of the utility model (the movement mechanism is made in the form of frames, each of which is formed by two levers connected to the frame by two cross members, the levers of the frames intersect and are hinged to form a hinged-lever mechanism such as scissors, the ends of the levers on one side of the mechanism are hinged with the upper and lower collet belt, respectively, and the opposite ends of the levers are installed in the respective guide grooves made in the upper and lower and collet belt, with the possibility movement along the grooves) in combination with the features common to the prototype, provide increased stability of the table in the “dining table” position.

This is explained as follows.

When executing the movement mechanism as a pivot-lever mechanism, such as scissors in the form of several frames, each of which is formed by two levers connected to the frame by cross members, the levers of the frames intersect and are pivotally connected, the ends of the levers on one side of the mechanism are pivotally connected to the upper and lower tsar girdles, respectively , and the opposite ends of the levers are installed in the corresponding guide grooves made in the upper and lower and the drawer belt, with the possibility of movement along the grooves, the upper drawbar jar with top in the position "dining table" (in the upper position) will be fixed to the ends of the arms at several points situated on the perimeter of the upper belt tsargovogo. The number of such attachment points is determined by the number of frames of the movement mechanism. So when executing a mechanism with two frames, the tsar’s belt with a tabletop will be fastened at four points located in the corners of the upper tsar belt. In the case of three frames there will be six such points of attachment. Fastening at four points (two frames) already provides high stability of the transformer table in the “dining table” position.

FIG. 8. Transforming table, tabletop transformation diagram, tabletop rotation in a horizontal plane by 90 degrees.

FIG. 9. Transforming table, tabletop transformation scheme, tabletops are laid out in a horizontal plane.

The transforming table comprises a lower drawer belt 1 with supporting elements in the form of legs 2, an upper drawer belt 3 with a tabletop 4 mounted on it, a mechanism for moving the upper drawer belt 3 to the “coffee / dining table” position, made in the form of a pivot-lever mechanism of the type scissors, and the mechanism for fixing the position of the table. The classic definition of “tsar” (tsar's girdle) is a horizontal frame of boards laid on an edge, combining the legs of a table or chair.

The countertop 4 is made folding, consisting of two equal halves, articulated using furniture hinges 5. The countertop 4 is supported by the upper drawer belt 3 and is connected to the cross bar 6 of the upper drawer belt 3 using a vertical hinge 7 with the possibility of rotation in a horizontal plane around a vertical hinge axis 7. In the folded state in the “coffee table” position, one of the halves of the countertop 4 is located above the other. In the unfolded state in the “dining table” position, both halves of the countertop 4 are located in the same horizontal plane with a doubling of the table area.

The mechanism for moving the upper collet belt 3 with the tabletop 4 to the “coffee / dining table” position is made in the form of frames, each of which is formed by two levers 8 connected to the frame by the cross-pieces 9. In the given example of the utility model, the movement mechanism is made in the form of two frames, but perhaps more of them, for example three. The levers 8 intersect and are connected using hinges 10 with the formation of a pivot-lever mechanism such as scissors. The ends 11 of the levers 8 on one side of the mechanism are connected to the upper 3 and lower 1 collet belts using hinges 12. The opposite ends 13 of the levers 8 are made with sliders 14, which are installed in the corresponding guide grooves 15 made in the upper 3 and lower 1 collet belt, with the ability to move along the grooves 15. This design eliminates the possibility of jamming of moving parts during operation of the mechanism.

The mechanism for fixing the position of the table is an emphasis 16, pivotally connected either to one of the drawer belts 1, 3, for example, to the upper 3 (Fig. 1, 2), or to the levers 8 of one of the frames (Fig. 3) with the help of straps 17 and hinges 18. Possible installation of an emphasis 16 and on the lower tsar belt 1, which is not fundamental. The emphasis 16 is made with the possibility of its support in one of the cross members 9 of one of the frames in the “dining table” position, which prevents the tabletop from moving 4 downward under load.

The levers 8 of the movement mechanism are interconnected by a damping mechanism, for example, a shock absorber 19. The number of shock absorbers 19 can be one or more. The damping mechanism ensures a smooth transition of the transformer table from one position to another.

The transformer table is made with a balancing mechanism in the form of tensile springs 20 connecting the ends 13 of the levers 8 installed in the guide grooves 15 of one of the drawer belts 1, 3 with the cross bar 21 of the drawer belt. In the above example, the balancing mechanism is installed on the lower side of the belt 1, but it can be installed on the upper side of the belt 3, which is not fundamental. The balancing mechanism makes it easy to transfer the transformer table from one position to another.

The table is transformed from the “coffee table” position to the “dining table” position and vice versa as follows.

In the "coffee table" position, the countertop 4 is in a folded state. The upper czar belt 3 rests on the lower czar belt 1. All details of the mechanism are located in the czar belts 1, 3 and are not visible. The weight of the upper collet belt 3 with the countertop 4 is balanced by tension springs 20 of the balancing mechanism. The height of the table in the "coffee table" position is 520 mm.

To translate the table into the “dining table” position, a slight effort is applied from the bottom up to the countertop 4 or to the upper tsar belt 3. The upper collet belt 3 with a countertop 4 easily moves up under the action of the springs 20 of the balancing mechanism. At the same time, the ends 11 of the levers 8 remain in place, rotating in hinges 12, and the opposite ends 13 of the levers 8 are moved in the guide grooves 15, providing a parallel rise of the upper collet belt 3 with the tabletop 4 to the “dining table” position.

When lifting the collet belt 3 with the tabletop 4, the stop 16 of the locking mechanism slides along the cross member 9, rotating in the hinges 18. When the specified height of the table is reached, the stop 16 automatically moves under the action of its own weight to the position in which it rests on the cross member 9, ensuring the table is fixed in the position of the "dining table".

The countertop 4 is rotated 90 degrees in a horizontal plane around the vertical axis of the hinge 7. The upper half of the countertop 4 is rotated in furniture hinges 5, translating it into a horizontal position and increasing the table area twice. The tabletop transformation diagram 4 is shown in FIG. 6-9. Table height in the "dining table" position 760 mm

To put the table in the position of "coffee table", all actions are performed in reverse order. The halves of the countertop 4 are folded, placing one above the other. The tabletop 4 is rotated in a horizontal plane around the axis of the hinge 7 90 degrees in the opposite direction. By lightly pressing the stop 16 from the bottom up, it is disengaged from the cross member 9. By pressing the countertop 4, the upper drawer belt 3 with the worktop 4 is lowered from top to bottom into the lower drawer belt 1.

The result of this transformation is a decrease in the height of the table and the area of the countertops, which correspond to the position of the "coffee table".
