Description

The present invention relates to device consoles for the arrangement of devices such as display screens or monitors on work or control desks or on desks.

In command, control and monitoring installations, it is often necessary to arrange several electronic devices in the area of entry and action of a person. This circumstance often leads to problems of space on the work plan and for this reason implies a rational division of it. In addition, with technical progress, these workstations often have to be equipped with new systems, devices and functions. In the event of a system change, new devices must frequently be in place for a certain period of time alongside the old devices on the workstation, to ensure the continuous safety of the installation. We therefore need flexible and expandable workstations on which we can place the most different devices, optimally according to their function.

Such consoles are described in document CH-A-675,291. These consoles of the prior art have the drawback that their adjustment in the horizontal direction is not possible from the work station, in order to adjust the optimal distance between the eyes of the operator and the monitor. Therefore, the object of the present invention is to create stable consoles which are also suitable for heavy devices, such as high performance monitors with screen diagonals larger than 20 inches, and which do not have this drawback.

The present invention therefore relates to consoles for tables or work desks, in particular for control consoles, comprising a support arm which has an essentially L-shaped or curved rounded shape, the ends of the support arm being arranged essentially perpendicularly one relative to the other, means being provided at the end of the first part on the underside of the desk for the horizontal fixing of said support arm, so that the second part projects upwards next to the desk or in front of it, and has at its free end means for receiving a device.

Work desks or control panels for power plants, industrial companies, etc. are generally stable constructions mounted on a system of metal supports. The supports of the consoles according to the present invention are generally fixed at one end to the desk by a screwing and / or by a clamping system. The bracket for the console protrudes under the table on the side of the desk opposite the workstation, and has an upward curvature so that the other end of the support arm can protrude beyond the top of the table. At this end of the support arm is mounted a fixing platform which serves to receive an apparatus platform. Between the device platform and the support arm is a sliding element which allows a horizontal movement of the device platform towards the desk or away from the desk. The apparatus platform can be provided with a turntable and / or a tilting plate so that an apparatus such as a monitor can be placed in an optimal position for the operator. The support arm may have a telescopic adjustment means such that it makes it possible to adjust the height of the device platform.

The support arm can be L-shaped or have a rounded curved shape which can be chosen according to aesthetic, economic or manufacturing technique criteria.

The console according to the invention allows the operator to position the device in a simple and optimal manner. Since high resolution monitors are often heavy, this is important so that this adjustment can be made in a safe and comfortable manner without jeopardizing the stability of the support system. Preferably, the device platform is modularly constructed, allowing individual elements such as the sliding element, the turntable and the tilt plate to be mounted or removed as required. The greatest possible flexibility is thus obtained, so that the same product can be mounted at will also without a tilting or rotating plate, the support arm then being less expensive. In a judicious manner, the sliding element is mounted at the very bottom on the mounting platform of the support arm, then the turntable and finally by the tilting plate. The support plate is placed above for receiving the corresponding device.

Preferably, the sliding element is constructed in such a way that a plate is mounted on the support arm which is connected in displacement with a sliding carriage, by means of a rail system. The rails can be arranged both on the sliding element and on the end piece of the support arm.

The invention is explained in detail with reference to the accompanying drawings which show only one embodiment. These show: fig. 1 a side view of a console according to the invention, fig. 2 a section through the corresponding support arm, and FIG. 3 an exploded view of the console shown in FIG. 1.

FIG. 1 shows a side view of a console according to the invention comprising a monitor 28 and a partial section of a control console 30. The console is fixed to the support rails 29 of the console 30.

The console consists of the horizontal part 2 of the support arm 1 with rectangular profile and a part 3 of the support arm 1 directed upwards. Part 2 and part 3 can be made in one piece or be connected to each other by a weld bead. On part 3 is arranged horizontally a mounting platform 9 adjustable in height.

This platform is fixed on a section 8 with a rectangular profile which is inserted telescopically in part 3 of the support arm directed upwards. The mounting platform 9 can be fixed at the desired height by snapping on the adjustment means 6 into one of the holes 7. The horizontal part 2 of the support arm is fixed to the two metal support rails 29 with a C-profile, by means of the screw 4 and a clamping plate 5. The cable channel 10 is used to conduct the cables 32 to the monitor 28 in an aesthetically satisfactory manner. This channel has the shape of a curved gutter. The closed cable channel is formed by its attachment to the support arm 1, and it is advantageously removable. This provides convenient access to cables that are already connected to a device or to cables that have connectors of the most diverse types. On the mounting platform 9 is screwed the guide plate 12 of the sliding element 11, a sliding carriage 14 which can be moved in the direction of the control console 30 or in the opposite direction towards the corresponding stop. The respective bolt 18 or 1 8a abuts here against the stop element 17 arranged laterally below the sliding carriage 14. Laterally, the sliding carriage 14 encloses the guide plate so that displacement is possible without hampering the stability. On the sliding carriage 14 is removably fixed a pivoting bearing 19 on which a tilting device 22 is removably mounted. The inclination is adjusted with an adjustment device which comprises an adjustment button 25, a spindle 26 and the levers 26w and 26b serving to adjust the inclination of the tilting plate 24. Advantageously, this adjustment takes place in continued. Finally, the device support plate 27 is fixed on the tilting plate 24 to receive the monitor 28. Thanks to this arrangement, it is obtained that the monitor is movable towards the body and that it can be turned around its own axis and adjusted for its inclination. The cables 32 leaving from the monitor 28 penetrate at the opening 20 into the cable channel 10 and exit therefrom at the opening 21 to be guided inside the body 30. Other cables come from the input units 31, which are located on the surface of the body, and are guided by corresponding openings inside the body.

Since devices such as monitors are frequently supplied with spherical feet and are therefore already tiltable and pivotable by themselves, it is possible, on these devices, to remove from the console the pivoting bearing 19 and the tilting device.

In such an embodiment, the console according to the invention has on its mounting platform 9 only a guide plate 12 towards the sliding element 11, the sliding carriage 14 and the device support plate 27.

Figure 2 shows a section through parts 3 and 8 of the support arm 1. The adjustment knob 6 with tapping and threaded rod is used for adjusting the two parts 3 and 8. The tapping is used for secure adjustment and the rod 6a is used for the engagement in the holes 7 and serves as additional security thanks to a lateral pressure on the part 8. At the bottom, on the side of the part 8, are fixed guide and stop plates 34 which cooperate with the plates 33 of guide and stop which are arranged at the top on the side inside the part 3 and which allow precise guidance. Thanks to a stop, the arrangement prevents an unexpected extension of the two parts. On the upper part of the part 8 is welded the mounting plate 9. Finally, we still see at the bottom and in profile, the horizontal part of the cable channel 10. I1 is screwed to the support arm by the socket 36.

Figure 3 is an exploded view of an apparatus platform according to the invention. Here we see the horizontal part 2 of the support arm 1 in which are the holes 4a which allow rough positioning of the device support arm. The device support arm 1 is connected by screws 4 to the clamping plate 5 which has threads. This fixing is done as shown in FIG. 1. The part 3 of the support arm directed upwards contains the section 8, which is pushed in telescopically, with the mounting platform 9. The height adjustment is made by means of the adjusting screw 6 and holes 7 (Figure 1) in the section 8. For a better overview, we have not shown here the cable channel 10 for guiding cables satisfactory from an aesthetic point of view. On the mounting platform 9 is fixed by means of holes the guide plate 12 towards the sliding element 11. The sliding carriage 14, which encloses the guide plate on the guide sides 13 by means of a folded rim, is inserted on the guide plate 12. An insert 15 made of plastic with a groove 16 is introduced into the enclosing part of the sliding carriage 14. This groove is used to receive the guide sides 13 of the guide plate 12. This allows the carriage to be guided 14 without play or blockages. The sliding carriage being inserted on the guide plate, there is provided a stop element 17 which achieves a limitation of the forward and backward movement insofar as the stop bolt 18 and 18a, respectively, comes in abutment on the stop member 17. If desired, one can also arrange an adjustment screw laterally on the carriage 14 in order to be able to fix the carriage in the desired position relative to the guide plate. It is also possible to mount on the sliding carriage a pivoting bearing (not shown, reference 19 in FIG. 1) which can be a standard product on the market. To minimize wear, it should be mounted as centered as possible below the device to be worn. A tilting device 22 is also mounted, the adjustment of which is effected by means of the adjustment button 25, the spindle 26 and the lever 26a. Turning the spindle 26 causes the block 26c to move. To limit the displacement and consequently the inclination, it has a stop element 23. The position of the articulation 26d is modified here, thus modifying the position of the tilting plate which can be pivoted about the axis 24a. The device support plate 27 is placed above it, which is preferably fixed by screws. As already mentioned, it is possible, as necessary or depending on the type of device used, to remove or refrain from mounting the pivoting bearing 19 and / or the tilting device.

The sliding device 11, constituted by the guide plate 12 and by the sliding carriage 14, can also be produced in another way.

For example, one can use a rail system, or the solution indicated in Figures 1 and 3 can be used mechanically inverted.
