Description

The invention relates to a device with a plate-shaped cover part, wherein around the circumference of the plate-shaped cover part around at least two support elements are arranged, which are arranged relative to the plate-shaped cover member slidably or pivotably.

A device of this type is known. For example, this is a table, around the circumference of a number of drawers or plates is arranged, which can be moved between an inserted or pivoted and an extended or swung-out position.

For some applications, it is desirable to provide a mechanism that accomplishes that when inserting or pivoting one of the drawers or plates, all others are retracted or pivoted and that accordingly follow when pulling or swinging out one of the drawers or plates and the other ,

Not only tables for the catering sector or game tables for card players for such applications are mentioned; such devices can also be used for presentation or training purposes when the slides are provided with a presentation graphic.

The disadvantage is that relatively complex measures generally have to be taken for a synchronous extension and insertion or for a synchronous pivoting out and in of several support elements (drawers, counter tables, presentation surfaces). This makes such devices expensive.

The invention is therefore the object of a device of the type mentioned in such a way that it is possible in a simple and thus cost-effective manner, a number of support members which are arranged around the circumference of a plate-shaped cover member around, simultaneously withdraw or expel or swing in or swing out.

The solution of this object by the invention is characterized in that in an plane parallel to the plane of the plate-shaped cover plate an actuating element is rotatably disposed relative to the plate-shaped cover member, each support member is connected by means of a connecting rod with the actuating element and wherein the connecting rods each articulated to the support elements and are arranged on the actuating element.

In this case, it is preferably provided that the device has a central axis, wherein the at least two carrier elements are arranged displaceable relative to the plate-shaped cover part along a radial direction relative to the central axis.

It can also be provided that the device has a central axis, wherein the at least two carrier elements are pivotable about an axis parallel to the central axis relative to the plate-shaped cover part.

The actuating element is preferably disk-shaped, d. H. it is a turntable in this case.

In order to ensure a low-friction movement of the carrier elements relative to the cover part, each carrier element can be arranged displaceably on at least one linear guide relative to the plate-shaped cover part. It is also possible that each support member is pivotally mounted on a bearing pin relative to the plate-shaped cover part.

The hinged connections between the connecting rods and the carrier elements or the actuating element may have hinge pins whose axis is aligned parallel to the central axis.

The plate-shaped cover part may have a polygonal shape. The number of corners of the polygonal shape can be twice as large as the number of support elements. This allows a space-saving accommodation of support elements, in particular in the form of drawers or plates.

At least one of the support elements may be provided with means by which the support elements can be fixed immovably relative to the plate-shaped cover part. These can be designed so that they can set the support elements in an inserted and in an extended or swung-out end position.

According to a preferred embodiment of the means is provided that they comprise a spring-biased bolt which is arranged directly or indirectly on the plate-shaped cover part and which can engage in a recess in one of the support elements.

An alternative solution provides that the means have a motor-driven pinion, which meshes with a toothing arranged on the outer circumference of the actuating element.

In order to ensure a low-friction rotation of the actuating element, in particular the turntable, provides a preferred embodiment of the invention, that a number of rollers are present, which are mounted on respective shafts which are directly or indirectly connected to the plate-shaped cover part, wherein the actuating element rests on the rollers. It is preferably provided that an axis of the shaft is arranged perpendicular to the central axis.

As one of the possible and preferred embodiments of the device according to the invention is provided that it is a table, wherein the plate-shaped cover part is arranged horizontally as a table top. In this case, the support elements can be drawers or storage shelves.

It is also possible that the support elements act as support elements for a table widening or extension. After that, therefore, if necessary, the support elements can be extended or swung out to then form the support surface for table top elements, with which the entire surface of the table can be increased. These additional table top elements can be provided in folding technique with flush hinges. In this case, the tabletop element can be stored folded in the unused state; When used as intended, the table top element is unfolded and placed on top of the table. The area of the plate-shaped cover part (Tabletop) is left out; The unfolded table top element rests only on the support elements.

Another preferred embodiment of the device is a presentation element, wherein the plate-shaped cover part can be arranged vertically in this case. The support elements may in this case be holders for a presentation graphic.

The proposed solution makes it possible to realize a device which makes at least two support elements (eg drawers, storage boards or boards, presentation surfaces) simultaneously extendable and retractable or extendable and retractable in a very simple and cost-effective manner. For this purpose, simple standard or standard parts can be used, so that the production costs remain low.

In the FIGS. 1 to 6 For example, a player's table 1 is to be seen as an exemplary application of the present invention having a foot 22 which supports a table top 2, but which, for reasons of clarity, are only shown in FIGS Figures 5 and 6 is shown. The table 1 has four drawers 3, 4, 5 and 6, which are generally referred to as support members in the context of this invention, since in other applications they typically carry material or articles in some form. The table 1 has a central axis 12 which is vertically aligned.

The table 1 is equipped so that when pulling out or pushing in one of the drawers 3, 4, 5, 6 all other drawers are simultaneously opened or closed simultaneously or synchronously. For this purpose, a turntable 7 is provided, which is rotatably mounted about the central axis 12 relative to the stationary table top 2. On the turntable 7 connecting rods 8, 9, 10 and 11 are articulated with one of its ends. The other end of the connecting rods 8, 9, 10, 11 is also articulated to the drawer 3, 4, 5, 6 are arranged.

As from the synopsis of FIGS. 1 and 2 or 3 and 4 is immediately apparent, this means that in the event that one of the drawers 3, 4, 5, 6 is closed or opened, as a result of the connecting rods 8, 9, 10, 11, the translational movement of the drawer is converted into a rotational movement of the turntable 7. This in turn means that the other three drawers are also pulled out or inserted over the other three connecting rods.

The connecting rods 8, 9, 10, 11 are in the embodiment in cross-section rectangular boards or flat iron, which are arranged at its two ends hinged to the drawer 3, 4, 5, 6 and on the hub 7. For this purpose, preferably hinge pins are used, whose axis is arranged vertically.

As can be seen, the table top 2 in the present case is octagonal (corners 13), wherein a drawer 3, 4, 5, 6 is arranged between two corners 13 and also extends approximately over the distance between the corners.

As mentioned, the table 1 is a player's table for, for example, card games. It may be useful to make arrangements that only after release by one of the players opening or closing the drawers 3, 4, 5, 6 is possible. For this purpose, means 14 are provided which allow a setting of one of the drawers 3, 4, 5, 6 in the inserted or extended state. In Fig. 4 the means 14 on a pinion 18, which can be driven by a small electric motor (not shown). The pinion 18 meshes with a toothing 19 which is arranged on the outer circumference of the rotary disk 4. Upon actuation of the electric motor and thus upon rotation of the pinion 18 thus the turntable 7 is rotated, which due to the connection of the drawers 3, 4, 5, 6 via the connecting rods 8, 9, 10, 11 causes all drawers 3, 4, 5, 6 are opened or closed simultaneously.

In the Figures 5 and 6 the means 14 are alternatively and simply executed: Here, the means 14 a bolt 16 which is fixed relative to the foot 22. The bolt 16 is spring biased; a spring 15 is indicated. Furthermore, an only schematically indicated recess 17 is provided, which may be incorporated in a drawer 3. More precisely, a respective recess 17 is provided for the inserted and for the extended state of the drawer 3. The spring-biased pin 16 therefore snaps in the two end positions of the drawer 3 in the recess 17, so that the drawer 3 is then blocked. For insertion or removal of the drawer 3, the bolt 16 is then withdrawn against the force of the spring 15 and the movement of the drawer is released.

For a low-friction bearing of the hub 7 relative to the foot 22 of the table 1 is provided that arranged around the central axis 12 around four shafts 21, d. H. attached to the foot 22. The shaft axes are arranged horizontally and have a star shape away from the central axis 12. At the end of each shaft 21, a roller 20 is arranged ball-bearing, which serves as a roller for the hub 7.

In catering tables, the support elements 7 can be used as extendable Abstelltische to turn off when needed food and drinks can. For other tables, the support elements can be used as area expansions.

The operation of the drawers requires due to storage by means of ball bearings only a small force. This is an easy operation of Hand possible. In the case of actuation by means of an electric motor can be ensured by using a self-locking gear between the engine and pinion that there is no accidental opening or closing of the drawers or support elements.

When used as a presentation element with extendable support elements for a presentation graphic, the device 1 is used with horizontally aligned central axis 12. The support elements 3, 4, 5, 6 can be illuminated for this purpose in any way, painted or provided with other graphic elements.

The geometric dimensions result in relation to the table top diameter and the number, width and extension depth of the support elements and the diameter of the turntable (Stemauszugsscheibe). Also, the length and articulation of the connecting rod plays a role here.

Commercially available components can be used to realize the device. This keeps the cost of the device low. Expensive special parts can be largely avoided.

In addition to the mentioned electromotive drive by means of pinion, a drive by means of toothed belt, chain or lifting cylinder can be envisaged. Preferably, the respective actuator sets on the outer circumference of the hub, so that the actuating forces can be kept low because of the then large lever arm to the central axis.

As preferred applications for the device according to the invention are again the catering (in particular catering), fair presentations, conferences and training called.

Of course, the four drawers or support elements shown in the embodiment are not mandatory. There must be at least two support elements; the number up is open and limited only by the space.

Thus, the invention allows a simple construction and stable functional star extract for a number of support elements that are synchronously movable.

In the embodiment according to the FIGS. 1 to 6 An octagonal table is shown. Of course, any other table forms can be provided as well. In this case, in particular round tables are preferred; also tables with certain designs, such. As those of a cloverleaf, are possible.

In the FIGS. 7 and 8th For example, a table 1 is seen as an alternative exemplary application of the present invention having a foot (not shown) supporting the table top 2. The table 1 has four Abstellplatten 3, of which only one is shown. The four storage plates are arranged equidistant around the circumference of the table 1 around. The storage shelves 3 are generally addressed as carrier elements within the scope of this invention, since they typically carry material or articles in some form in other applications. The table 1 again has a central axis 12, which is vertically aligned.

The table 1 is equipped so that when swinging out or pivoting in one of the storage plates 3 all other storage plates simultaneously or synchronously also swung or swung become. For this purpose, the turntable 7 is again provided, which is rotatably mounted about the central axis 12 relative to the stationary table top 2. On the hub 7 connecting rods 8 are articulated with one of its ends. The other end of the connecting rod 8 is also hinged to the storage tray 3.

Each storage tray 3 is pivotally mounted relative to the table 1 by means of a bearing pin 24, wherein the bearing pin 24 permits a pivoting movement about an axis 23 parallel to the central axis 12.

While in Fig. 7 the turntable 7 is shown in a first position A '(indicated at a defined circumferential point of the turntable 7), it is in Fig. 8 in a rotated by an angle φ position B 'to see.

As from the synopsis of FIGS. 7 and 8th is immediately apparent, this means that in the case that one of the storage plates 3 is pivoted, the pivoting movement of the storage tray 3 is converted into a rotational movement of the turntable 7 as a result of the connecting rod 8. This in turn means that the other three storage shelves are also swung out or swiveled in via the other three connecting rods.

The connecting rods 8 are in the embodiment according to Fig. 7 and 8th in cross-section rectangular boards or flat iron, which are arranged at its two ends hinged to the storage tray 3 and on the hub 7. For this purpose, preferably hinge pins are used, whose axis is arranged vertically.
