The beam permits an integrated cabling or wiring with further working planes arranged in accordance with an ergonomic space concept.

Description

The invention relates to work furniture according to the preamble of claim 1.

Various furniture devices and furniture programs with work furniture and in particular with work tables for office and conference rooms and for laboratory, technician and computer workplaces are known. Modular furniture systems were developed to meet the requirements of the various workplaces. Although work furniture can be assembled according to the modular principle according to the respective requirements and often a subsequent equipment, for example with a second level, allows the installation and installation of additional devices, such as power supply devices, ventilation devices and various laboratory equipment, these known work pieces of furniture are not constantly growing functional and ergonomic demands as well as the requirements for the best possible use of space with an appealing and flexible design.

A work table with a base frame and a height-adjustable table top is known from EP 0 107 162 A1. The base frame is provided with a horizontal stiffening element underneath the table top. A multifunction rail runs parallel to the stiffening element, which is particularly suitable for attaching visible and organizational walls, Lighting heads and other additional devices and for connection to other work tables is formed and can serve as a cable duct.

Furthermore, in WO 91/16 835 a support leg, known as a cheek, for an office work table is known, which at the same time is intended to serve as a stand for further pieces of office furniture. In order to achieve relatively large vertical cable ducts and to be able to use extruded profiles for the production of the cheek, two edge profiles are screwed to a web wall connecting them and the space is covered with an inner and an outer insert wall. A table top is carried by the parallel cheeks. In order to achieve sufficient stability of the individual cheek, it is necessary to connect the two vertical profiles with at least one web wall.

An office table known from DE 86 12 889.2 U1 has a cross member between two height-adjustable support feet. A cable duct is arranged below a table top and height-adjustable with the table top.

These known solutions do not adequately meet the changing and constantly growing functional and ergonomic requirements for versatile work furniture.

The invention has for its object to provide a modular work furniture, which is put together both as an elegant office and conference table and as a stable and visually appealing computer, laboratory and technician workstation and retrofitted at any time in a particularly simple manner or can be retrofitted, which can also be optimally used and appropriately set up in terms of height and depth according to the technical and ergonomic workplace requirements and can be adapted subsequently and with particularly little effort to changed requirements.

According to the invention the object is achieved by the features of claim 1. Useful and advantageous configurations are contained in the subclaims and in the description of the figures.

According to the invention, in a room ergonomically designed piece of work furniture which has a table top resting in the area of its side edges on support arms, support feet with vertical profiles arranged below the support arms with T-slots and interior spaces for receiving a height adjustment device for the table top as well as horizontal foot brackets and cable ducts in the area of the vertical profiles and has a horizontal cable duct as a stiffening connection between the vertical profiles, double column feet are provided as support feet, each of which has the front vertical profile and a spaced and identically designed rear vertical profile. The height adjustment device is provided in particular in the front vertical profiles for the front table top. The horizontal cable duct is designed as a common cross member for the paired front vertical profiles and rear vertical profiles and fastened in the external grooves of the vertical profiles. In addition to the front table top defining a first working area or a first working level, at least one further working level, in particular a rear table top, is attached to the rear vertical profiles fixable, which is arranged or designed taking into account an ergonomic handle line.

By forming cable spaces in the area of the table top and further horizontally arranged working levels and / or in the area of the vertical profiles, flexible and integrated cabling is possible. To stabilize the vertical profiles, which are almost spaced apart in table width, the cross member provided in the rear area of the table top serves as a stiffening connection, which is connected to the vertical profiles and can be used as a horizontal cable duct or cable space.

Aluminum extrusion profiles are preferably provided as vertical profiles, which enable a connection to other components of the modular system. In a particularly advantageous embodiment, the vertical profiles have an almost rectangular cross section with chamfered or rounded corner areas and, in addition to T-slots in both side faces, a T-slot in the end faces, the side faces of the vertical profiles on the work furniture according to the invention parallel to the side edges of the table top or run in alignment with them. A centrally arranged interior is complementary to a vertically adjustable inner tube and has, for example, a rectangular cross section. The inner tube is connected to an associated support arm of the table top and is vertically adjustable via a sliding guide for height adjustment of the at least one front table top.

To realize the sliding guide, sliding surfaces or sliding elements, in particular made of plastic, can be arranged on the inner tube. For example, there is a fixation possible via an adhesive, plug-in or snap-in connection. The sliding surfaces or sliding elements advantageously act as tolerance compensation at the same time. Permagleitflächen or vertical elements can also be used for sliding guidance, which protrude into the interior, for example in a T-shape, in such a way that the inner tube is slidably guided on the crossbar.

In a particularly expedient embodiment, half-shell-like sliding elements are provided on circular cavities in the vertical profile. The circular cavities are formed in particular in the area of the end faces of the vertical profile and delimit the central interior.

The height of the at least one table top can be adjusted continuously and can range from 680 to 810 mm. However, this height adjustment can also be set up at a distance, for example in a grid dimension of 30 mm or in fixed heights, for example at a height of 720, 750 or 780 mm, and can be operated manually, for example with a crank or with the aid of a motor and with one in the lower region the column feet or the vertical profiles arranged spindle or a cylinder-piston unit.

In order to enable convenient operation and handling of the height adjustment device, the hand or motor control is expediently arranged on the front of the table and is easily accessible.

If the height adjustment device of the work table comprises a display device, an ergonomically favorable table height can be set and controlled in a particularly efficient manner. A display device for the table height to be set is particularly recommended if several employees have to work at one workplace. The display device can be arranged in the area of the vertical profiles or in the area of the operating elements for the height adjustment.

The cable duct cross member, which connects two parallel support feet arranged on both sides of the table top, is fastened in the upper area of the vertical profiles of the support feet, preferably with fastening elements which are held in the T-slots of the vertical profiles.

For stable and particularly suitable training for technicians, IT or MCR workstations, the work furniture is provided with double support feet, which for stabilization are equipped with a common, e.g. trough-shaped cross members are connected. The crossbeam, which can also be used as a horizontal cable duct, connects the vertical profiles, which are arranged in pairs and spaced one behind the other, across the entire table width with the double support foot arranged on the opposite side to form an extremely robust substructure. The cable duct is in particular stepped trough-shaped and runs in a preferred construction below the rear longitudinal edge of the table top.

The table top is arranged as a first, front working level of the work station and can not only be adjustable in height, but also, if necessary, also adjustable in inclination and / or displaceable and extractable. An inclination adjustment can be implemented, for example, with the aid of a pivot axis that interacts with the support arms in a connection area of the inner tube.

Horizontal adjustability can be achieved via slide rails in the area of the support arms. In a preferred embodiment, the table top, as the first working level, can be pulled out to the front via a sliding plate guide and, if appropriate, also removed. The sliding plate guide can be designed, for example, as a split bar with a sliding plate guide arranged in the front table area and with a sliding plate guide arranged in the rear table area. The strips or

Sliding plate guides are inserted with pins from below into holes in the table top and partially screwed. The front sliding plate guide has blocking elements, for example blocking springs, to limit and pull it out safely. These protrude downwards and come into contact with a certain extension dimension when the table top is pulled out or in engagement with a corresponding counter element or a contact surface in the area of the support arms. Since the slide guides are provided with longitudinal openings, it is possible to press in or raise the locking springs from below, so that the table top can be pulled further forward or fully.

A cover is expediently provided for the horizontal, trough-shaped cable duct support, which cover can be designed to be removable or pivotable. A horizontal gap over almost the entire cover for the entry and exit of cables and lines is equipped with a sealing cable duct, for example with double sealing lips or brush strips, so that an orderly line routing from and to the devices of a work station is guaranteed.

An intermediate space in the area of a double support foot between the two vertical profiles arranged and spaced one behind the other, which is covered with a specially designed veneer to improve the overall optical-aesthetic impression, is expediently used as an additional vertical cable duct. In order to ensure that the connection between the vertical and horizontal cable ducts is in line with the shape and the design of the support arms, a panel is provided in the upper area that provides a removable surface or predetermined breaking points Breakthrough and for cable routing from the vertical to the horizontal cable duct.

An advantage is the possibility to use the vertical profiles, in particular the rear vertical profiles of the double support feet, to enlarge the work surface and the workplace optionally in addition to the front, first work level, with a second, backwards working level and / or with a table structure as a third to equip the higher level.

A piece of work furniture with a height and / or inclination-adjustable second level can be used in particular for CAD workstations in which the second level can be used to accommodate monitors and can be adjusted according to the individual wishes with regard to height and inclination.

A cross member running between the first and second levels is particularly advantageous to use as a cable duct for devices and devices arranged on both levels.

For example, a horizontal cable duct arranged as a stiffening connection or cross member between vertical profiles, in particular spaced apart in table width, can be formed from a plurality of longitudinal profiles which are detachably connected to one another on their longitudinal edges to form an approximately triangular cross section.

It is advantageous to use at least one basic profile for fastening to the vertical profiles of the column feet on both sides. The basic profile is for this purpose provided a fastening area, which can be designed, for example, as a cavity for receiving an adapter-like connecting element. The connecting element can be fastened in the T-slots of the vertical profile and with the aid of a clamping part in the cavity of the basic profile in order to hold the cable duct securely.

The base profile is expediently connected as a corner profile and via snap-fit connections at the end to an approximately arch-shaped cover or to a rear profile or an intermediate profile which serves to widen the cable duct.

For reasons of stability, the longitudinal profiles, which are made in particular of aluminum, are designed as hollow profiles which have T-slots and / or screw channels for the optional fastening of accessories, for example sockets, cable holders, etc.

To cover the vertical cable ducts, which are formed in the space between double support feet or in a veneered rear area of a support foot, color-highlighted or specially designed caps can be attached. The caps are provided with locking elements and can be clipped on. A support structure-like element is expedient, which is provided with recesses and noses for holding top and side surfaces.

To set up a third level, for example for a measurement and control work station with measurement, control and regulation tasks or also for realizing a functional partition and the like, the rear vertical profiles of the double support feet can be provided with self-centering extension profiles in particular.

In order to ensure a uniform and coordinated overall impression, the extension profile is almost identical to the vertical profile of the column or double column feet. In particular for a third working level directly adjoining a rear area of the front table top, it makes sense to provide an extension profile that is open to the inside. As a result, cables can be routed from the vertically arranged profiles into the horizontal cable ducts or supports or directly to the devices in a particularly efficient manner.

If the third working level is not directly connected to the front worktop or table surface, an elastic, detachable cover of the longitudinal profile opening of the extension profile is recommended. In an advantageous manner, so-called soft lips or brush strip arrangements can be provided for the elastic covering and cable routing.

For example, a cross strut, which serves as a positioning level or as a storage shelf for receiving different assemblies, components and / or devices, can be attached to upwardly elongated vertical profiles.

It is advantageous to design an upper receiving plane as a horizontal, upper cable duct which, for example, has a housing base with holding or guiding elements that can be swung open downwards. In order to improve the operability or reading of the devices arranged on the third level, it can also be designed to be tilt-adjustable, the usual devices having to be attached to or in the vertical profiles of the third level.

A table top extending to the rear vertical profiles, which is provided as the first, front working plane, is expediently provided in the area of the rear vertical profiles with complementary recesses to the cross section of the vertical profiles. When using the table top for a workplace without a table structure or without a third level, these recesses are expediently covered with a removable, for example with a snap-in or insertable plate-shaped insert. The respective upper, open end faces of the vertical profiles are provided with a plate-shaped cover cap adapted to the outline of the vertical profiles, which e.g. can be pressed into the circular interior of the vertical profiles with pegs.

In a further development of the work furniture, an ergonomic design is combined with a particularly effective use of space or space and an extraordinarily advantageous workplace concept is created.

Thereafter, a housing area for accommodating devices is provided in the workplace from space-economical and ergonomic aspects, which is provided almost outside a viewing and gripping area, so that in particular the table top as the first, front working level is principally kept free of devices. The workplace space concept according to the invention provides a fourth level, which is arranged essentially in the lower area below the table top and accommodates basic supply devices such as PCs, plug-in cards as well as power supply devices, transformers and the like. A rear table top can be provided as a second level, while a connection field lies in the ergonomic grip area and accommodates, for example, devices such as, in particular, measuring and display devices.

A particularly effective use of space results if the display unit, in particular a monitor, is fastened, for example pivotably, to an extension profile of the third level outside the front worktop.

The entire table surface or worktop as a first level remains free in this work space concept for one or more test objects and for additional documents, such as circuits or special devices. A fourth-level housing design enables effective and effective HF shielding of the various devices, which can additionally be protected against one another by an HF shielding arrangement. This reduces the probability of errors and power loss at test stations. An installation of, in particular, starable fan assemblies is provided in order to prevent heat build-up while minimizing noise pollution. Furthermore, a uniform service and maintenance concept can be implemented, which results in a reduction in maintenance costs. By operating the devices uniformly, especially with an appropriate program, errors are reduced and shorter training times are made possible.

An integrated wiring or wiring is expediently provided, which also includes bus systems and enables computers to be networked without problems. This improves the transmission options for measurement data, their acquisition, evaluation and processing. Another advantage is better production monitoring. The integrated cabling means less susceptibility to malfunction of the entire device complex or the workplace and a more rational inspection. Unintentional loosening of cables or wiring is almost impossible.

A major effect of the integrated arrangement of personal computers, basic supply devices, etc. is less space, an extremely stimulating overall impression of a workplace and material savings as a result of the elimination of individual housings.

In a further development, the work furniture comprises at least one table base cabinet to be arranged below the table top, in particular a mobile container, which can extend up to close to the table top and in a suitable adaptation to a stepped trough-shaped cable duct support and / or to a device area forming a fourth level approximately complementary deck area is provided. This design enables a base cabinet or a roll container to be optimally positioned in a particularly simple manner, and it can also be fixed, for example with the aid of a Velcro fastener on the rear cable duct carrier. The base cabinet or roll container can be designed to accommodate various attachments, for example to accommodate open trays for in particular office material or for basket-like and / or mat-equipped attachments, depending on the workplace requirements. If a further table level, for example an extendable table level, is arranged below the table top, the mobile container has a correspondingly lower height. In a further embodiment of the work furniture, so-called active edges are provided in the area of the front longitudinal edge of the table top, which are designed to accommodate additional storage options, for example insert trays.

The work furniture according to the invention can be arranged in a particularly simple and visually appealing configuration to form a corner combination. A corner table top is attached with its support arms to the inner tube of the associated vertical profile if the corner table top is to be adjustable in height together with the table tops adjoining on the side. Otherwise, a fastening in the longitudinal grooves of the vertical profiles can be provided.

Support feet or double support feet, which are provided with detachable and / or exchangeable foot brackets and which can advantageously be disassembled and reassembled in the use position of the work furniture or the work table, have proven to be particularly advantageous. An expedient constructive design of a base element, which connects a vertical profile with a horizontal foot bracket, and an end connection area of the foot bracket ensure a self-centering and a self-locking receptacle and an uncomplicated fastening. In principle, a change of a foot arm can be carried out without interference during a test procedure or during a measurement and the like.

In the area of corner combinations, for example, relatively long, front and disturbing footrests can be avoided and exchanged for shorter footrests.

In particular with work furniture, which has to meet diverse requirements and changing concepts within the framework of a modular work station system, the necessity of a conversion may arise, for example the establishment of a further work level to accommodate additional devices. A deeper worktop than The first work level or a work table structure as the third work level can then require the installation of a longer or an additional rear foot arm to ensure sufficient stability or stability.

A particularly simple construction and an extremely simple assembly and disassembly of a foot bracket is ensured if a vertical profile of a column foot assigned to the table top is connected to a horizontally arranged foot bracket which can be removed and replaced in the use position of the work furniture. If a base element designed to be complementary to the vertical profile is arranged below the vertical profile and is detachably connected to the vertical profile, for example by means of screw connections, and has a front insertion opening and an easily accessible connection area, it is possible to insert a foot extension, which has a connecting block, horizontally into the base element and fasten. A particularly advantageous releasable fastening is achieved at the connection area of the base element or at the connection block of the foot arm via an inclined screw connection. For particularly stable work furniture that realizes an optimal room concept, plinth connectors can be arranged, which connect two vertical profiles of a double support foot at a distance. If necessary, a shorter foot extension can be inserted into the rear base element. From the point of view of production technology and material economy, the use of a U or double U profile which is open at the bottom, in particular an aluminum, die cast or sheet steel deep-drawn part, is advantageous. A base part which is open at the bottom is expediently used as the base element. The foot boom and Base element construction allows a particularly simple assembly and any replacement of a foot bracket on site without time-consuming rearrangement work. The insertion opening of the base elements can expediently be closed with the aid of cover elements if no foot extension is provided.

Figures 1a to 1f show examples of different variants of a piece of work furniture according to the invention, which is constructed in a modular manner and can be equipped with different components according to the intended use. Basically, work furniture 1 according to the invention has a table top 6 as a front, first work plane, which is in the area of its Lateral edges rests on wedge-shaped support arms 8 and can be adjusted in height and / or inclination and / or can be extended forwards, for example 20 cm. The extendibility can be achieved via sliding and guide elements between the underside of the table top 6 and the support arms 8.

The table top 6 is supported via support feet 2 connected to the support arms 8, etc. via double supports - feet 12, which are provided with at least one horizontal foot bracket 30, a base element 20 and vertical profiles 10, 11. In an advantageous embodiment, the foot arm 30 is wedge-shaped in analogy to the support arm 8, which is of almost the same length, and provides a functionally and optically successful overall impression with T-grooves 18 formed in the longitudinal direction on the vertical profiles 10 (see FIG. 2).

1a shows a technician's work station with a double support foot 12 and a cross member 5 which is arranged as a load-bearing element and cross bracing and at the same time can be used as a horizontal cable duct and has a stepped trough-shaped design. The cross member 5 is fastened with lateral end faces (not shown) in the T-grooves 18 (FIG. 2) of the side faces of the front vertical profiles 10 and the identically designed, rear vertical profiles 11. 1a has a particularly deep, height-adjustable table top 6 as a first work plane and a backward adjoining table top 7 as a second work plane, which is rigid or displaceable in height on the rear vertical profile 11, for example via an angle element 3 in the T-slots 19 (see Fig. 2) is attached. The double support foot 12 has a rear base element 20 in addition to the front one Base element 21, which forms a unit with a base connector 22 and, together with the cable duct cross member 5, forms a stable substructure for the work furniture, in the exemplary embodiment for a technical workplace. The elements for height adjustment of the table top 6 are covered between the front vertical profiles 10 and the support arms 8 with a flexible sealing element, for example with a rubber bellows 9 or a rubber sleeve, in a form-fitting and detachable manner.

Fig. 1b shows e.g. a CAD work station, which also has a double support foot 12 and a trough-shaped cable duct cross member 5. As a first working level, a front table top 6 is connected to the front vertical profile 10 in an adjustable manner, while a second, rear table top 7 is supported on a rear vertical profile 11 by means of a visible inner tube 14 and a pivot axis 29. Analogous to the technician workstation according to FIG. 1a, a horizontal cable duct cross member 5 serves to supply the devices present on both table tops 6, 7. The depth of the second table top 7 is adapted to a rear foot bracket 31, which, like a front foot bracket 30, is detachably fastened in an associated base element 20 or 21, the vertical profiles 10 and 11 being connected to these base elements 20 and 21, respectively.

1c shows a further technician's work station, which essentially corresponds to the technician's work station according to FIG. 1a, but only has a first working level in the form of a particularly deep table top 6 which extends beyond the rear vertical profiles 11.

1d shows an office and technician workstation with a table top 6 which is height-adjustable in steps, the height adjustment of which is described in connection with FIGS. 2 to 5.

In the Fig. 1e office work table shown, which is provided with a support foot 2 with a front foot extension 30 and a short, rear foot extension 31, the vertical profile 11, the associated base element 21 and the base connector have been removed and the rear foot extension fixed. The table top 6 is adjustable in height, while a conference table according to FIG. 1f has a table top 6 which rests rigidly on a support arm 8 and is supported on support feet 2.

Fig. 2 shows in a horizontal section the formation of the vertical profiles 10, 11 of the column feet 2 and the double column feet 12. The vertical profiles 10, 11 have an almost rectangular cross section, with beveled corner areas 23 between parallel and / or aligned to the side edges of the Table tops 6, 7 extending side surfaces are each provided with two T-grooves 18 and shorter end surfaces each with a T-groove 19. The corner areas 23 can also be rounded. In a central, almost rectangular inner space 16, an inner tube 14 (see FIGS. 3 to 5) can be adjusted in height via a spindle (not shown). Two spindles can also be provided, for example in the circular interior 25 of the vertical profile 10, 11. The inner tube 14 is a steel tube and is complementary to the interior 16 of the aluminum extruded profile 10, 11. The steel inner tube 14 is adjusted vertically and in stages by means of a sliding guide, a grid dimension being predetermined by the spacing of bores 24 along the inner tube 14 and being 30 mm, for example. The inner tube 14 has an upper, enlarged connection area 17 which is provided with a circular bore 27 and an oval bore 28 which is for connection to at least one, serve for example with a crank or with a motor-operated spindle in an interior of the vertical profile 10, 11. A pivot axis 29 for an inclinable table top 7 (see FIG. 1b) can also be formed in the connecting area 17. For sliding guidance of the inner tube 14 in the interior 16, adjoining the interior 16, half-shell-shaped sliding elements 26 are arranged, which can have separate sliding linings. Alternatively, sliding or permagliding surfaces can also be glued onto the inner tube 14.

FIG. 6 shows a corner office combination as a further exemplary embodiment of work furniture which can be adapted to the requirements of the workplace and the spatial situation. The same reference numerals are again used for identical features. The height of two table tops 6, which are connected and supported by support arms 8 with double support feet 12, can be adjusted. To form a third working level 33, which at the left worktable 6 is a functional partition 34 with a filing plane 35 and horizontal grooves 36 for fastening various devices, for example lamps, panels and the like (not shown), on the rear vertical profiles 11 Double support feet 12 self-centering extension profiles 37 are attached, the upper end faces of which are covered with a cover cap 38. In the area of the extension profiles 37, a corresponding recess 32 is formed in the table top 6, which can optionally be covered with a plate-shaped insert (not shown). Below the table top 6 runs in the rear area a cable duct cross member 5, which is connected to a vertical cable duct 13 formed by a cover between the front vertical profile 10 and the rear vertical profile 11.

FIG. 6 illustrates the optically and aesthetically successful design of an office work table with an additional construction level 33. An additional level 33 is also mounted on the right table top 6 via a schematically illustrated adapter 39, which is preferably fastened in the rear area of the support arms 8. A corner plate 4 is fastened to the inner tubes of the adjacent vertical profiles 10 via holding elements (not shown). To ensure the required legroom, the foot supports in the corner area must be removed from the front base elements 20.
