Description

Kombinationsmobel

The invention relates to a combination furniture that can be used as a table and as a blackboard, with a worktop that can be positioned and fixed in different positions, the worktop being attached to a guide that is height-adjustable on a wall bar that is to be attached vertically to an inner wall , wherein the guide consists of a movable guide part and a fixed guide part.

In the prior art, both tables and blackboards are different

Types known.

Folding tables to be attached to the wall save space when not in use, but are not height-adjustable.

According to DE 297 01 939 U1, a foldable desk and table arrangement is known in which a front and a rear bearing axis are arranged parallel to one another near the floor, on which supports are mounted which have a pivotable one

Support the plate.

Usual wall boards are adjustable in height and also take up little space, but cannot be used as a table. It was therefore tried with various arrangements to create combined table-table systems.

According to DE 20 12 595 AI universal table-table system is known, in which both a height adjustment and an inclination of a plate is made possible, the plate being attached to two rails or supports so that

Inclination and height are adjustable. Furthermore, DE 298 16 186 Ul specifies a height-adjustable wall panel-desk combination in which a tiltable rectangular plate can be used as a desk writing side and as a board. For this purpose, height adjustment is provided on two wall strips using additional desk strips. When folded down, the plate is supported by means of swiveling supports.

With these arrangements, it is disadvantageous that the two wall strips are required, which must be aligned exactly parallel, so that there is a risk of jamming and tilting, which makes operation more difficult. Furthermore, the two strips stand in the way of an aesthetic design of the overall arrangement, which is further reinforced by a third strip which serves to secure the panel when folded up. Another disadvantage is that the arrangements only allow a gradual adjustment of the working height.

The invention is therefore based on the object of specifying a combination furniture of the type mentioned, in which the working height of the worktop can be adjusted in a simple manner with little play, both in steps and continuously, and that the high aesthetic requirements to be placed on living room furniture and the other designs needs to be met.

The object is achieved according to the invention with an arrangement which contains the features specified in patent claim 1.

Advantageous refinements are specified in the subclaims.

The invention is characterized by a number of advantages. The combination according to the invention makes it possible to easily and safely adjust the height of your worktop with almost no play. In addition, the arrangement takes up little space. It is particularly suitable as a growing painting, bastei and writing instrument for children. This is particularly advantageous in versions in wood, which with a board for

Paint are provided. But it is also possible that the worktop is designed as a magnetic board. It can be produced inexpensively in both wood and metal. For example, when folded up, it can serve as a magnetic or cork-designed pinboard on which you can take notes when folded down. Furthermore, versions for office and other work purposes are possible, in which the board is designed as a whiteboard (so-called whiteboard) or as an electronic display (e.g. touchscreen). Due to the height adjustability, the arrangement is particularly suitable where people of different sizes use the device alternately or where it is used both standing and sitting.

The invention is explained in more detail below using an exemplary embodiment.

Figure 7 is a perspective view of a design for a

Securing element and

Figure 8 shows the arrangement of the securing element on the movable guide part.

As can be seen from FIGS. 1 to 3, the combination furniture has a wall strip 2 which is fastened vertically to a wall 1 of the room in a suitable manner, preferably by means of dowels. On the wall bar 2, a guide 3 is arranged, with the help of which the worktop 6 can be moved up and down. The fixed guide member 3.1 is firmly connected to the wall bar 2 and the worktop 6 is coupled to the movable guide member 3.2. With a locking device 9, the movable guide member

3.2 are fixed at the desired working height. The movable guide element 3.2 is provided on its left and right inside with sliding blocks 3.3 which engage in grooves 3.4 machined on the side of the wall bar 2 and slide therein. To fix a set altitude, the locking screw 3.5 is tightened

Sliding blocks 3.3 on the lateral surfaces of the grooves 3.4 and thus ensure a firm and play-free fit of the entire arrangement. It is also possible that nuts are arranged at regular intervals in the fixed guide member 3.2, in which the movable guide element 3.2 can be secured by screwing. For height adjustment takes place in this

Fall after loosening the threaded connection moving the movable Guide member 3.2 to another position on the fixed guide member 3.1, where there is also a nut and finally the tightening of the fastening device.

An advantageous embodiment is that the fixed guide member 3.1 is integrated into the wall rail by simply working the grooves 3.4 into it.

In a further embodiment, a T-slot is incorporated in the movable guide element 3.2. Instead of the T-groove, a dovetail groove or another suitable groove can be attached. In this groove, the movable guide element 3.2 is guided with a counterpart corresponding to the shape of the groove and can be locked in any position with a locking device 9 in the form of a clamping screw. It is also possible to make a groove 3.4 on the front of the wall strip 2.

A stop element 15 can be attached to the fixed guide member 3.1 in order to prevent the movable guide member 3.2 from slipping downward and possibly from falling down the entire arrangement. The stop element 15 can be arranged on an outer surface of the fixed guide member 3.1 or in the groove 3.4.

On the movable guide element 3.2, a carrier 4 is fastened horizontally, at right angles to the wall strip 2, on which the swivel 5 has the

Worktop 6 is attached so that it can be folded up and down about a horizontal axis.

Below the worktop 6 there are one or more supports 8 which can be pivoted about a horizontal axis. It is also possible to arrange the pivotable supports 8 so that they can be pivoted about a vertical axis. For this purpose, an additional support 10 is attached to the lower edge of the movable guide element 3.2, which is arranged parallel to the support 4, at a distance from the lower edge of the support 4, which corresponds to the height of the pivotable supports 8. The supports 8 are provided with pins 8.1 and 8.2 which can be rotated in guide holes in the carrier 4 and in the additional carrier 10. In the folded-down state, the worktop 6 is placed on the supports 8 which have been pivoted out. In order to ensure an ergonomically favorable position of the worktop 6 for writing, drawing and for carrying out similar work, it is expedient to choose the dimensions of the supports 8 so that the worktop 6 is in a folded-down state in a slightly downwardly inclined position. If a horizontal position of the worktop 6 is desired, this can be done in a simple manner by attaching the plug-on attachment 16 shown in FIG. 8, which is provided with slots which form-fit the supports 8 that are folded out.

Depending on the set working height, the furniture can therefore be used as a table or as a standing or sitting desk.

In the vicinity of the upper end of the movable guide member 3.2, a securing element 7 is attached, with which the worktop 6 can be secured against being accidentally folded down when it is folded up. For this purpose - as shown in FIG. 1 - magnets can be used, which are located on the back of the worktop 6 and at the corresponding point on the

Wall bar 1 are attached. It is also possible to lock the device with a latch that can be swiveled to the left and right. A particularly advantageous embodiment of the securing element 7 is shown in FIGS. 7 and 8. It has the shape of a right-angled metal bracket which is pivotably attached to the two outer sides of the movable guide member 3.2. The metal bracket 7 consists of a vertical Surface 7.1 and a U-shaped horizontal surface 7.2. For the swiveling movement, downward tabs 7.3 are bent on the lateral legs of the horizontal surface 7.2, in which there are bores 7.4 which form the bearing points for the swiveling movement. The axis of rotation is always below the upper edge of the worktop 6, so that unintentional loosening by pulling on the worktop 6 is reliably prevented. As an additional security measure, the horizontal surface 7.2 of the metal bracket 7 can be at a distance from the movable guide member 3.2, so that there is an opening into which an additional securing device 17 can be inserted, which prevents the metal bracket 7 from folding up. This is particularly beneficial in order to avoid unintentional actuation of the latch by small children.

If the worktop 6 is folded up and locked, the furniture can be used as a blackboard.

It is expedient to attach the arrangement to the wall 1 in such a way that a few millimeters of space remain between the movable guide element 3.2 and the wall 1. In versions in which only a groove 3.4 on the front of the wall bar 2 is used for guidance, it is possible that the movable guide member 3.2 with the worktop 6 attached to it, even if the overall construction is adequately fastened to the wall bar 2 due to the distance mentioned and the inevitable guide play, the worktop 6 also has an undesirable freedom of movement, which leads to a wobble.

This can be avoided with the arrangement shown in FIGS. 5 and 6. It enables a height adjustment of the wall panel-folding table combination without causing damage to the wall and at the same time prevents the movable guide member 3.2 from wobbling with the worktop 6. For this purpose, round depressions 13 are provided on the left and right outside of the carrier 4.1, on the rear 4.2, that is to say the side facing the wall. The diameter of the recesses 13 must be somewhat larger than the distance between the upper edge and lower edge of the carrier 4. Threads are worked into the recesses 13; in the application example, this is done by driving in a nut 14. A threaded pin 11 is screwed into this thread, the length of which is such that it does not protrude from the round recess 13 on the back of the carrier 4 when screwed in, but on the other hand it does so can be turned out far that he is able to the distance between the back of the carrier 4 and the

Balance wall. The set screw 11 or a disk 12 connected to it can be easily turned by hand. This is also possible if the height-adjustable wall panel-Z folding table combination is attached to the wall rail 2 and this is attached to the wall. In the example shown, this is achieved in that a lock screw is used as the threaded pin 11, which is firmly connected to a washer 12 of larger circumference. The disc 12 and with it the lock screw can also be easily screwed in and out by hand if the height-adjustable wall panel / folding table combination is attached to the wall rail and this is attached to the wall.

When using the wall panel-Z folding table combination, the two setscrews 11 are screwed into the recesses 13 by rotating the disks 12 before the movable guide element 3.2 is pushed up or down. Between the back of the carrier 4 and the wall 1 and between the back of the movable guide member 3.2 and the wall 1 there is now a sufficient distance so that the guide 3 can be pushed up and down on the wall bar 2 without damaging the wall , If the movable guide element 3.2 is fastened in the desired position, the screws are removed from the disks by turning the disks 12

Wells 13 unscrewed until they hit the wall. This will turn on two points on the left and right outside of the upper support 4, the distance between the wall and the back of the upper support 4 is equalized and the work surface 6 is not wobbled.
