Description

The invention relates to a lifting system for a height-adjustable workstation system and a workstation system with at least one such lifting system.

There are workstation systems are known in which by means of a worktop, a work surface is provided as a table, with behind such a worktop on an additional worktop, for example, screens are placed. These screens can be adjusted with respect to the front worktop or person working on this worktop by making the rear worktop adjustable with respect to the front worktop. For example, it is possible to adjust the height of the rear worktop with respect to the front worktop. In conventional workstation systems, however, the setting options are limited.

An object to be solved is to provide an improved concept for a workstation system which allows a more flexible adaptation of the workstation system.

This object is achieved with the subject matter of the independent claims. Embodiments and further developments are described in the dependent claims.

For example, at least one lifting system is provided for a height-adjustable workstation system, which has a first, front worktop and a second, rear worktop can carry. For this purpose, the lifting system has, for example, a pedestal with a foot element and a height-adjustable part, as well as a console which is rigidly connected to the height-adjustable part of the pedestal. On the console, the first worktop can be attached.

The improved concept is based on the idea that a back element is provided on the console, which is rigidly connected to the console and has a recess. This recess is preferably provided on the side remote from a user of the workstation system of the lifting system. The recess makes it possible to flexibly position a support element, which is provided for supporting the second, rear worktop, while ensuring a stable arrangement.

Accordingly, in an exemplary embodiment of the lifting system, a support member is mounted within the recess of the back member, the support member having a retaining member adapted to secure the second work panel. In particular, in this case the support element is detachably connected in the recess of the back element, for example by a screw or the like. This allows the support element or the second worktop to be flexibly mounted both in the resulting height and in the distance to the first worktop.

In various embodiments of the lifting system, the rear element can be connected in different height positions with the console, for example via a screw connection. As a result, increased flexibility in the design of the lifting system is achieved.

In one embodiment of the lifting system, the rear element completely encloses the support element at at least one point in the horizontal direction. In other words, the support element can preferably only be inserted from above and / or below into the recess of the rear element in order to be fastened there. As a result, the stability of the overall arrangement of the lifting system is improved.

Preferably, the support element is designed as a lifting element, which has a height-adjustable lifting part, which is adapted for movement relative to the rear element. Due to the relative movement to the rear element, a relative movement to the first worktop or to the console is accordingly ensured. In this embodiment, the retaining element is preferably connected to the lifting part. The height-adjustable lift allows for further flexibility in customizing a workstation system. Such an adaptation is possible and intended, in particular, during operation or in a completely assembled workstation system.

In various embodiments, the rear element is U-shaped or L-shaped. The running as a lifting element support element is in this case secured in the lower region of the back element. For example, accordingly, the lifting element is fixed in the horizontal leg of the rear element. Such a configuration is particularly suitable, for example, for workstation systems in which the rear, second worktop is not intended to be lowered much lower than the front worktop. However, you can the actual height difference can be adjusted by suitable choice of the leg lengths of the L-shaped back element.

In the case of a U-shaped configuration of the rear element, it is possible, for example, to provide the attachment of the support element or of the lifting element in the lower, horizontally extending part of the rear element, so that a trench can be formed inside the U-shaped rear element, so to speak, within which the second work surface can be retracted is. For example, in a workstation system, for example, a flat screen on the second worktop can be sunk into this trench. Thus, a user of the workstation system can, for example, optionally sink or display a screen and thereby obtain increased flexibility when using the workstation system or the lifting system.

In various embodiments, the support member has slots extending vertically on at least two sides and at least one connecting part fixed in the slots and secured within the recess of the back member. By the vertically extending slots, the flexibility can be increased in particular in the height adjustment of the support element. For example, a basic configuration with the same lifting system can be made specifically for different workplace requirements without having to rely on a special redesign of the workstation system or of the lifting system.

In various embodiments of the lifting system, the rear element is designed, for example, such that it has two vertically extending plates, between which the support element is mounted. The two plates are for example outside the recess with cross braces fastened together and thus form a kind of support for the support element, which is preferably secured between the two plates.

The plates have, for example, a vertically extending hole pattern in which the support element can be fastened in different height positions. This embodiment can be particularly well combined with the previously described embodiment with the vertically extending slots in the support element. For example, a modular combination between pedestal, console, rear element and support element is achieved.

In a further embodiment of the lifting system, the holding element is designed to be displaceable horizontally relative to the rear element. In particular, the displaceability is designed such that a distance between the holding element and the console is variable. The displacement can be done by a rail system or the like and manually, electrically or hydraulically operated.

In one embodiment of the lifting system, this further comprises a further pedestal with a foot element and a height-adjustable part, which is firmly connected to the rear element. Here, the support element is fastened in the rear element between the two uprights. Thus, the lifting system, for example, two height-adjustable uprights, which are mechanically coupled via the rear element. This allows greater stability for the lifting system, especially for large or heavy workstation systems. At the other, rear pedestal can also be provided on the height-adjustable part of a console or the like, where, for example, a rear wall or the like can be attached.

Furthermore, it is possible in this embodiment of the lifting system with two vertical columns to provide a further support member which is mounted within a further recess of the rear element, and which has a further holding element, which is adapted for attachment of the second worktop. This embodiment is particularly suitable for workstation systems, which have a larger footprint, especially on the second worktop.

In one embodiment of a workstation system, this includes a first and a second lift system according to one of the previously described embodiments. Further, in the workstation system, the first worktop is provided, which is connected to the consoles of the first and second lifting system, and the second worktop, which is connected to the holding elements of the first and second lifting system. This makes the workstation system flexible.

Furthermore, it is possible that, in particular for a large-scale workstation system, this has at least one additional lifting system, which carries the load of the first and second worktop.

Preferably, in the workstation system, the consoles of the first and second lifting systems are connected via a support element.

In the workstation system, additional elements can be flexibly integrated. For example, the workstation system includes a cable tray disposed below the first or second worktop. It is further possible that the workstation system comprises a flexible cable guide element which is arranged on one of the support elements. As a result, even with a height adjustment during operation of the workstation cable can be safely guided.

A height adjustment of the individual elements can be done by various known methods. For example, a hydraulic, an electro-hydraulic or an electric motor drive is provided for the height adjustment. For this purpose, a control is preferably provided in the workstation system, which carries out the control of the individual height-adjustable elements. Such a control can also ensure that a height adjustment of the individual elements is synchronized, so that no undesirable differences in height of elements that should have the same height, so for example, a uniform height of each worktop is guaranteed.

Also, a possibly existing distance setting the second, rear worktop can be done by motor.

The invention will be explained in more detail below with reference to several exemplary embodiments with reference to FIGS. The same reference numerals denote elements or components of the same function. As far as components or components correspond in their function, their description is not repeated in each of the following figures.

In FIG. 1 Figure 3 is a perspective view of a basic exemplary embodiment of a lift system for a height-adjustable workstation system. The lifting system comprises a pedestal 1, which has a fixed part 2 and a foot element 3, which ensures a secure state of the lifting system. At the upper end of the fixed part 2 is a not visible here height-adjustable part 5, with a console 7 is rigidly connected. On the console 7, a first worktop can be attached to a user can work directly.

Going away to the rear or left is connected to the console 7, a rear element 9 rigidly, which is given in this embodiment in that console 7 and rear element 9 are made of the same piece of material. In different embodiments, however, it is also possible that the rear element is rigidly mounted on the bracket 7.

The rear element 9 has a recess 13, which allows a vertical passage through the recess 13 and the rear element 9. The recess 13 is formed in the rear element 9 in this embodiment in that the rear element 9 has two vertically extending plates 8, 10, which are not covered horizontally in the region of the recess 13.

Within the recess 13, a support member 11 is fixed, which has a holding element 15. The holding element 15 is fastened in this embodiment to a height-adjustable lifting part 17, which allows a movement in particular of the holding element 15 relative to the rear element 9 or to the fixed part of the support element 11. On the holding element 15, a second worktop can be attached, which is set up, for example, for the wearing of visualization systems or screens.

In the plates 8, 10, a breadboard is provided, which is visible in the illustration only for the plate 8. By this breadboard individual attachment of the support member 11 can be achieved. This is particularly favorable for an individualized basic adjustment of the support element, which in the in FIG. 1 illustrated embodiment is designed as a lifting element. In alternative embodiments, however, the support element 11 can also be designed without height adjustability, so that a desired height for the holding element 15 or the worktop mounted thereon can still be achieved via the perforated grid.

The lifting system of FIG. 1 also has a flexible cable guide element 23, which is attached, for example, to the rear side of the support element 11. There is also a cable duct 25 is provided, which is mounted on the back of the fixed part 2 of the pedestal 1.

FIG. 2 shows a detailed view of an embodiment of a lifting system, for example, in FIG. 1 illustrated embodiment in which in particular the area around the attachment of the support member 11 is shown on the rear element 9. It can be seen that in the stationary part of the support member 11 vertically extending slots 19 are provided, which are incidentally also on the opposite side of the support member 11. In the slots 19, a connecting part 21 is fastened via connecting elements such as screws. Such a connecting part is preferably also on the non-visible back of the support member 11. Further, this is already for FIG. 1 mentioned hole pattern in the plate 10 of the rear element 9 recognizable, in which via corresponding screw the connecting part 21 is fixed. A corresponding arrangement can also be found on the non-visible back in the plate. 8

The construction with the slots 19 and the connecting part 21 allows both with a height-adjustable support member and with a fixed support member an individual and flexible adjustment or default for the height of a mounted on the support member 15 worktop. In addition, a simple mounting of the support member 11 in the rear element 9 is possible by the construction mentioned.

The described embodiments of the lifting system allow the construction of a workstation system with two levels. The first, front level with a possible first countertop serves as a working plane, while the second, rear plane can be used with a possible second worktop, for example, as a visualization plane.

In various embodiments, it is also possible that the holding element 15 is not fixed, but horizontally displaceable connected to the other parts of the support member 11. This can be achieved for example by a rail system or other functional fittings. The horizontal displacement can be carried out manually or by an electric or hydraulic drive. The horizontal adjustment of the holding element 15 or the associated worktop allows flexible configuration of the distance between the front working level and the rear visualization level, so that ergonomic conditions can be optimally produced for a user of the resulting workstation system.

FIG. 3 shows a perspective view of another embodiment of a lifting system, which on the in FIG. 1 illustrated embodiment. In particular, the front part of the lifting system is designed substantially the same as in the representation of FIG. 1 so that a repeated explanation of corresponding elements is dispensed with.

In the embodiment of the FIG. 3 the rear element 9 is rigidly connected to the console 7 via a screw connection. In this case, during assembly of the lifting system, a desired height position of the rear element 9 with respect to the console 7 can be selected by providing a corresponding hole pattern on the console. This increases the flexibility of the lifting system.

Furthermore, in the embodiment of the FIG. 3 Accordingly, the pedestal 31 has a fixed part 32 and a height-adjustable part 35, which is hidden by a rear bracket 37, however. The rear console 37 is in particular rigidly connected to the height-adjustable part 35 of the rear pedestal 31. The pedestal 31 has a foot member 33, which ensures a secure state of the rear pedestal 31. At the rear pillar 31, another cable duct 27 is mounted in analogy to the cable duct 25.

The rear console 37 is similar to the console 7 by a screw rigidly connected to the rear element 9, which extends like a bridge between the front console 7 and the rear console 37. Again, by adjusting a height adjustment possible. The plates 8, 10, which extend over the entire length of the bridge-like rear element 9, form in the rear part of a further recess 43, within which a further support member 41 is attached to a further holding element 45. Preferably, the support elements 11 and 41 are similar in their construction or are constructed substantially identical. For example, the rear support element 41 has a height-adjustable lifting part 47, on which the rear retaining element 45 is attached.

The embodiment of the lifting system, which in FIG. 3 allows a larger workstation system than the embodiment of FIG. 1 , In particular, another, third worktop can be fastened on the rear holding element 45, which can be used to design an additional visualization plane or the like allows. Accordingly, for example, the support elements 11, 41 designed as lifting elements can be set differently in height. In alternative embodiments, however, it is also possible to attach a second worktop both on the holding element 15 and on the holding element 45 so as to obtain a larger area visualization level or the like. For example, a shelf and / or a rear wall for the workstation system can be attached to the rear console 37.

In further modifications, it is also possible to dispense with the provision of the second support element 41, so that a lifting system with two vertical columns 1, 31 and only one support element 11 is formed. As a result, for example, the depth of the workstation system can be reduced or adapted to a desired space requirement.

FIG. 4 shows a perspective view of a basic embodiment of a workstation system, which is shown for clarity without worktops. The workstation system in this embodiment comprises two lifting systems according to the in FIG. 3 illustrated embodiment. Accordingly, the explanation of the lifting systems is omitted in detail. To stabilize the two consoles 7 are connected to each other via a support member 51. Further, a cable tray 53 is disposed between the brackets 7 and the rear elements 9, which is located at fully assembled workstation below the first worktop. Preferably, in the rear part of the workstation system, for example, between the rear brackets 37, a further support element is provided, which is not visible in the selected perspective.

In the illustrated embodiment of the workstation system, the two lifting systems are arranged substantially parallel to each other. As a result, for example, a conventional substantially rectangular workstation system can be created. However, a round or polygonal workstation system can also be created by appropriate choice of the worktop mold, which is mounted on the consoles 7. Furthermore, it is also possible that the two lifting systems are not parallel, ie at an angle to each other, which facilitates the construction of a rounded or polygonal workstation system. In the latter case, for example, the support members 51 and the cable tray 53 may be formed with a corresponding round or polygonal shape. It should be noted that the final shape of the workstation system is independent of the design of the lifting systems, so that the various embodiments of the lifting systems modular workplace systems can be created in any form. In particular, there is no new design requirement for the lifting systems.

In further embodiments, the workstation system can also have more than two lifting systems, so that in particular wider workstation systems can be created.

FIG. 5 shows an embodiment of a completely constructed workstation system, which in particular the in FIG. 4 illustrated embodiment comprising the two lifting systems. In the illustrated embodiment in FIG FIG. 5 is mounted on the consoles 7, a front, first worktop 61, while on the non-visible holding elements of the support members 11, 41 a second, rear worktop 63 is attached. The front worktop 61 serves as a working plane for a user of the workstation system, while the rear, second worktop 63 serves as a visualization plane. In particular, a plurality of screens 71, 72, 73, 74, 75 are mounted on the visualization level, which can be changed in height relative to the front working level. At the rear consoles 37, a rear wall 65 is attached. Below the countertops 61, 63 a cabinet system 81 is provided, which is preferably at least partially constructed around the pedestals 1, 31 around. In particular, in the rear region of the cabinet system 81 computer units or computer systems can be accommodated, which drive the screens 71 to 75. Accordingly, the flexible cable guide member 23 leads into the cabinet system 81.

In the embodiments presented above, a lowering of the rear plane, for example the visualization plane, is limited by the position or shape of the rear element 9. At the top, a height adjustment is limited only by the stroke of the support elements 11, 41.

FIG. 6 shows an alternative embodiment of a lifting system, in which the rear element 9 is designed in particular U-shaped. Incidentally, the embodiment is based substantially on the in FIG. 3 illustrated embodiment of the lifting system. By the U-shaped configuration of the rear element 9, for example, almost to the bottom, and the attachment of the support member 11, which is designed as a lifting element, in the deepest region of the U-shape, it is possible, the second work surface 63 relative to the first work surface 61 a lot to lower deeply. This can be achieved, for example, that a flat screen, which is on the second worktop 63, so deep below the worktop Can be lowered so that the screen for a user of a resulting workstation system is no longer visible. In other words, it is achieved that a screen can only be driven out of the sink when needed. For example, in such a construction in the lowest position of the rear work surface 63, a larger work area can be achieved via the first work surface 61, for example, with a corresponding cover of the recess or the like.

The embodiments described above represent only a few exemplary variants, but they can be combined with each other as desired. In particular, the support members 11, 31 may be fixedly secured in the rear element 9 or adjustably screwed or hooked in height. On the support members 15, 45 of the support members 11, 41 plates of wood material, plastic, metal or support systems for screens, visualization systems or the like, for sliding hardware such as statements, carriages, linear drives or the like can be attached. The support members 11, 41 may be executed without height adjustment or be designed as lifting elements for additional manual, hydraulic, electric or electro-hydraulic height adjustment.

The arrangements described are particularly suitable for highly installed workstations, which can be used in control rooms, operations centers, control centers, operations centers, control rooms or the like for all areas such as energy, transport, supply, disposal, security, air traffic control and the like.

The illustrated embodiments are particularly useful for workstations that allow ergonomically optimized working with large-scale visualization systems of any kind. Various visualization systems, such as TFT display groups, which can also be arranged one above the other in several rows, or large displays of any size, for example up to 100 ", and weight, for example, up to more than 1000 N per display, are also possible, even new, not yet known visualization systems can be attached to the universal holding elements ergonomically optimized.

The length or size of the back element 9 can be matched to the requirements of the desired workstation system, in particular in the case of a bridge-like design.

For example, by appropriate fittings, the visualization level or the second worktop in relation to the working level or the first worktop can be adjusted to an ergonomically optimized viewing distance from the workplace. The setting can for example be done electrically via a corresponding control system. Any adjustment distances can be freely defined here.

A cable management of the workstation system can be installed between the back elements 9. The cable trays, which can be folded down, for example, can form an ergonomically matched cover and at the same time provide optimum access to cable management.

In order to achieve a corresponding stroke in the uprights 1, 31 or in the lifting elements 11, 41, for example, electric spindle drives, preferably be used in a known telescopic design.
