Holder for holding a monitor on a table or similar piece of furniture

The invention relates to a holding device for holding a monitor associated with a computer on a table or similar piece of furniture, with a plate-like base for the monitor, which can be pivoted into different pivot positions about a pivot axis that is horizontal in the position of use and can be locked in the respective pivot position.

With a table equipped with such a holder, the monitor can be swiveled into a position that is comfortable for the respective user, so that it can not only be horizontal with the screen standing vertically, but also tilted backwards and downwards so that the user can look at the screen at an appropriate angle with a healthy posture.

In this context, the present invention is based on the object of designing the holding device as compact and uncomplicated as possible and making the position and location of the monitor even more variable for further adaptation to user requirements.

This task is solved in a holding device of the type mentioned at the beginning in that it contains a fastening device that is or is to be fixedly arranged on a rear area of the piece of furniture facing away from the user and a support device that can be fixed to the fastening device at different heights, whereby the support device has a cantilever device that establishes the connection to the fastening device and, when fixed to it, protrudes from the fastening device in a fixed position and a swivel unit that contains the base, whereby the swivel unit is connected to the area of the cantilever device facing away from the fastening device in a swiveling manner and can be locked in the respective swivel position and the swivel axis is arranged below the base in a plan view from above.

This also provides the option of height adjustment. This height adjustment is independent of the swiveling of the base, so that all possible swivel angles can be set in any height position.

Since the height adjustment and the pivoting are independent of each other, the mechanical details can be simple, resulting in a straightforward structure.

Since the cantilever device protrudes from the furniture-side fastening device in the assembled state and the pivot axis is arranged below the base, the holding device according to the invention can also be designed as a table attachment,

which can be attached to the back of the table, which remains unchanged.

The fastening device does not have to be integrated into the piece of furniture, but can, depending on its individual design, be subsequently arranged on the piece of furniture, so that retrofitting the table or similar is easily possible.

Appropriate embodiments of the invention are specified in the subclaims.

An embodiment of the invention will now be explained with reference to the drawing.

Figure 4 shows the securing element arranged on the cantilever arm shown in Figure 1 in a section perpendicular to the drawing plane of Figure 1 along section line IV-IV, with the securing element being shown in its effective position in engagement with the perforated rail, which is also shown in section.

The holding device 1 shown in the drawing serves to hold a monitor 2 associated with a computer (PC) not shown on the back of a table 3 or similar piece of furniture, of which only a rear vertical wall 4 and a worktop 5 on the top of the table are indicated.

The user therefore sits on the user side of the table, which is located to the right outside of Figure 1, and can look backwards at the screen 6 of the monitor 2 arranged opposite him on the back of the table 3.

The holding device 1 has a plate-like base 7 on which the monitor 2 is placed. In the embodiment, the base 7 is formed by a plate made of wood or similar material. The base 7 is part of a swivel unit 8, which together with a cantilever device 9 forms a support device 10. This support device 10 can be attached to a fastening device 11 at different heights.

layers (the height direction is indicated by the double arrow 12), with the fastening device 11 being arranged on the back of the table 3. The fastening device 11 can form a component of the table 3 from the outset or, as in the exemplary embodiment, it can be a fastening device that can be attached later.

The support device 10 is secured to the fastening device 11 by means of its cantilever device 9 and, in the secured state, projects away from it, i.e. backwards with reference to the table 3. The swivel unit 8 is connected to the area of the cantilever device 9 facing away from the fastening device 11 in a pivotable manner and can be locked in the respective pivot position. In this way, the plate-like base 7 can be pivoted about the pivot axis 13, which is horizontal in the position of use, via the pivot unit 8 firmly connected to it and can be locked in the desired pivot position. This pivot axis 13 is located below the base 7 in a plan view from above. The cantilever device 9 therefore extends to below the base 7, where the pivot unit 8 is hinged to it. The pivot direction is indicated by the double arrow.

The base 7 and with it the monitor 2 can therefore be adjusted independently of one another in the height direction 12 and in the swivel direction 14, so that the height and inclination of the screen 6 can be adapted to the user.

In the exemplary embodiment, the cantilever device 9 has two cantilever arms 15, 16, which are arranged at a distance from one another in the direction of the pivot axis 13 and overlap in Figure 1, so that only the cantilever arm 15 is visible there. These cantilever arms 15, 16 can be secured to the fastening device 11 with their front end area on the one hand and reach under the base 7 on the other hand, where they are each connected in an articulated manner to a pivot bearing part 17, 18 arranged on the underside of the base 7 and belonging to the pivot unit 8. This articulated connection corresponds to the pivot axis 13, whereby, since the two cantilever arms with the respective associated pivot bearing part are arranged at a distance from one another in the pivot axis direction, it is not a continuous pivot axis but two pivot axis parts each assigned to a cantilever arm and a pivot bearing part. Each cantilever arm 15, 16 with associated pivot bearing part 17, 18 is assigned a locking device (to be described later) with which the pivot bearing part can be locked in the respective pivot position on the cantilever arm.

If the stability is sufficient, only one such pivot bearing part and only one cantilever arm could be present.

The two units, each formed by a cantilever arm and a pivot bearing part, are of identical design in the embodiment, apart from the mirror symmetry with respect to the center plane between them.

·* »··« tt #♦·» ft

The respective cantilever arm 15 or 16 rests flat against the respective associated pivot bearing part 17 or 18, whereby the cantilever arm 15 or 16 is arranged inside, i.e. on the side of the pivot bearing part 17 or 18 facing the other cantilever arm.

The cantilever arms 15, 16 and the pivot bearing parts 17, 18 have a plate-like shape and are each formed by a sheet metal body. The pivot bearing parts 17, 18 each have an angled fastening area 19 or 20 on their upper side, via which they are screwed to the underside of the plate-like base 7. Otherwise, the pivot bearing parts 17, 18 protrude downwards at a right angle from the underside of the base.

As already mentioned, each unit formed by a cantilever arm and a swivel bearing part is assigned a locking device for locking the swivel bearing part in the respective swivel position. In the exemplary embodiment, this locking device has a row of holes 21 arranged on the cantilever arm and running in the circumferential direction (reference is made here to the swivel axis 13), to which at least one hole 22 is assigned on the swivel bearing part, so that in the various swivel positions of the base 7, one of the holes 21 of the row of holes on the cantilever arm is aligned with the hole 22 on the swivel bearing part and a locking bolt 23 can be inserted through the aligned holes 21, 22. In the exemplary embodiment, several such holes 22 are arranged on the respective swivel bearing part, which are distributed over the circumference, the arrangement in this context being such that the row of holes 21 on the cantilever arm

at least essentially extends over an arc angle that corresponds to the arc angle between two consecutive holes 22 on the pivot bearing part. The distance between the holes 21 is therefore significantly smaller than the distance between the holes 22. Each of the holes 22 can therefore be aligned over each hole in the row of holes 21 on the cantilever arm, so that with the help of the locking bolt 23 a relatively large number of fixable pivot positions of the pivot unit 8 are obtained.

In the embodiment, the holes in the row of holes 21 are threaded holes and the locking bolt 23 is a threaded bolt, so that the locking bolt 23 can be inserted through the respective hole 22 on the pivot bearing part and screwed into the relevant hole 21 of the cantilever arm.

It is understood that the hole arrangement can also be reversed, so that the hole row corresponding to the hole row 21 is arranged on the pivot bearing part and the hole corresponding to the at least one hole 22 is arranged on the cantilever arm.

The pivot bearing parts 17, 18 have a circular arc-shaped outline, so that they have the appearance of a partial circular disk, along the circumference of which the holes 22 are arranged.

For stability reasons, the cantilever arms 15, 16 have a U-shaped cross-section in which they have longitudinal edge regions 24, 25 bent away from the respective pivot bearing part.

As already indicated, the cantilever arm device 9 formed by the two cantilever arms 15, 16 in the embodiment in the state fixed to the fastening device 11 protrudes upwards and backwards from the piece of furniture 3, as can be seen in particular from Figure 1. The fastening device has not been drawn in Figure 2.

The support device 10 formed by the swivel unit 8 and the cantilever device 9 is expediently a separate unit from the fastening device 11 and can be removably attached to the fastening device. To adjust the height, the entire support device is simply removed and reattached at a different height.

The fastening device 11 is formed by at least one perforated rail 26 with a row of fastening holes 27 extending in the longitudinal direction of the perforated rail. The perforated rail 26 extends, when it is fastened to the piece of furniture 3, in the vertical direction 12. Furthermore, the cantilever device 9 has at least one, in the exemplary embodiment three, suspension hooks 28 for each perforated rail 26 for hanging in the fastening holes 27 of the perforated rail 26. In the case of several suspension hooks 28, these are arranged one above the other at a distance from one another corresponding to the hole spacing of the fastening holes 27, so that the several suspension hooks 28 each engage in a fastening hole 27 and are hooked there.

In the embodiment in which the cantilever device 9 is formed by the two cantilever arms 15, 16, two such

- 10 -

Perforated rails 26 are present, each of which is assigned to one of the cantilever arms 15, 16. In the drawing, only the perforated rail 26 facing the viewer is visible (Figure 1). The perforated rail 26 has, as can be seen from Figures 1 and 4, a U-shaped cross-section, with the fastening holes 27 located on the crosspiece 29. The two lateral perforated rail legs are designated 30 and 31. The fastening holes 27 are expediently elongated holes extending in the longitudinal direction of the perforated rail.

The suspension hooks 2 8 protrude from the cantilever arm front side facing the fastening device and are obtained during the manufacture of the cantilever arms by appropriate punching of the metal sheet.

In the embodiment, the suspension hooks 28 have an L-shaped appearance, with the hook leg 32 protruding from the cantilever arm front side being shorter in the vertical direction 12 than the elongated holes 27. A hook leg 33, which points downwards in the position of use, is attached to this hook leg 32 at a distance from the cantilever arm front side that is adapted to the material thickness of the perforated rail crosspiece 29. The arrangement is such that during assembly the entire suspension hook 28, including its hook leg 33, fits through the respective fastening hole 27 and, after it has been inserted and the cantilever arm in question is lowered, its hook leg 33 engages behind the perforated rail crosspiece 29, so that the locking required to secure the cantilever arm is achieved.

Such perforated rails with correspondingly attachable supports are otherwise particularly common for the production of wall shelves.

When the cantilever arms are suspended, there is a gap in the relevant fastening hole 27 above the hook leg 32 that is at least as long as the hook leg 33 protruding downwards. This gap between the suspension hook and the upper end of the fastening hole enables the entire suspension hook 28 to be pushed through the relevant fastening hole 27 when the cantilever arm is in a raised position. In order to prevent the holding device 1 and its cantilever arms 15, 16 from being inadvertently lifted for any reason and thereby coming out of engagement with the perforated rails, in the embodiment a safety element 34 is arranged on each cantilever arm in the area of a suspension hook 28 above the latter, which is spring-loaded and, when the suspension hook 28 is hooked into the fastening hole 27, engages in the aforementioned gap between the suspension hook and the upper end of the fastening hole, so that the relevant fastening hole 27 is filled and the respective cantilever arm cannot be lifted. The securing element 34 is mounted on the relevant cantilever arm so that it can move in a direction perpendicular to the perforated rail 26 and is pressed by a spring 35, in the embodiment a helical spring, in the direction away from the cantilever arm towards the perforated rail into its effective position, in which it engages in the fastening hole 27 with a locking lug 36 forming its front end. The securing element 34 is pushed out of the fastening hole against the force of the spring 35.

hole 27 into its ineffective position, so that when the securing element 34 is in the ineffective position, the cantilever arm in question can be unhooked from the perforated rail.

In the embodiment, the securing element 34 is formed by a two-legged plastic piece, the two legs 37, 38 of which are connected to one another at the end forming the locking lug 36 via a film hinge 39 and otherwise run along both sides of the relevant cantilever arm 15. The two legs 37, 38 are locked together at 41 through a recess 40 in the cantilever arm 15 so that the securing element is held on the cantilever arm. The spring 35 is contained between the two legs 37, 38 in a further recess 4 in the relevant cantilever arm 15 and is supported at one end on the cantilever arm and at the other end on the securing element. The recesses 40, 42 are sufficiently long so that the securing element can be moved back and forth between its active and inactive position. A handle 43 or 44 is molded onto the two legs 37, 38.

By moving the cantilever arms on the perforated rails, i.e. by inserting the hooks 28 into other fastening holes 27, the holding device 1 can be adjusted in height.

The at least one perforated rail 26 does not have to be present on the piece of furniture 3 from the outset, but can be attached later if required. For this purpose, the perforated rail 2 6

a clamping device with which it can be releasably clamped to the vertical furniture wall 4. This clamping device contains at least one upper suspension bracket 45, which has a U-shaped cross section and is connected to the upper end of the perforated rail. This connection is made by means of a threaded bolt 46, which passes through the perforated rail 26 and is in threaded engagement with one leg 47 of the suspension bracket 45, this leg 47 being arranged on the side of the perforated rail crosspiece 29 facing the furniture wall 4. The suspension bracket 45 is placed on the furniture wall 4 by gripping the upper edge area of the furniture wall 4, so that when the threaded bolt 46 is tightened, the furniture wall 4 is clamped between the perforated rail legs 30, 31 on the one hand and the other leg 48 of the suspension bracket 45 which grips behind the furniture wall 4.

The clamping device also expediently contains a lower suspension bracket 49, which is connected to the lower end of the perforated rail via a threaded bolt in the same way as the upper suspension bracket 46, surrounds and engages behind the lower edge area of the furniture wall 4, so that clamping takes place again when the threaded bolt is tightened. The conditions here are the same as with the upper suspension bracket 45, so that a further description is unnecessary.

In addition to the subsequent attachment of the perforated rails fastened in this way, there is the further advantage that they can be moved when the threaded bolt 46 is loosened on the furniture wall 4, so that even in this, for

The monitor 2 can be adjusted in a direction parallel to the pivot axis 13 by moving the fastening device and thus the entire holding device 1.

The swivel unit 8 also contains a stop device 50 which stands up in the area of the back of the base 7 and which supports the monitor 2 to the rear. This stop device 50 is adjustable both in the vertical direction 12 and in the direction 51 towards or away from the user, so that its position can be adapted to the dimensions of the monitor. For this purpose, a two-armed angle piece 52 is provided which contains a bearing arm 53 which extends in the vertical direction and on which the stop device 50 is mounted so that it can be moved telescopically. A guide rod 54 of the stop device 50 is inserted into the hollow bearing arm 53. The angle piece 52 also forms an adjustment arm 55 which is essentially at a right angle to the bearing arm 53 and which is arranged on the underside of the base 7 so that it can be adjusted in the direction 45 towards or away from the user. For this purpose, the adjustment arm 55 engages through a bearing member 56 fixed to the base 7. The guide rod 54 can be fixed in its respective position on the bearing arm 53 and the adjustment arm 55 and thus the entire angle piece 52 can be fixed in its respective position on the bearing member 56. For this purpose, the guide rod 54 and the adjustment arm 55 can each have a row of holes, to which a corresponding hole on the bearing arm 53 or on the bearing member 56 is assigned, as indicated in Figure 1. In the respective position of the guide rod 54 on the bearing arm 53 or the adjustment arm 55 on the bearing member 56, a locking can be carried out using a suitable locking device.
