Abstract

A column for suspending a device provided with fastening elements from a ceiling or the like. The column comprises a mounting which is adapted to be attached to the ceiling and a pillar whose one end is connected to the mounting and whose other end is connected to a mounting plate. At the mounting plate, a number of supporting arms are each movably fastened by means of a pin element and pivotable in a plane parallel to the mounting plate. Each supporting arm has en elongate opening configuration which extends in the longitudinal direction of the supporting arm and in which one of the fastening elements is secured. To position the fastening element in the opening configuration, the fastening element can be placed in a suitable position therein and/or the supporting arm can be moved in its longitudinal direction relative to its pin element.

Claims

1. A column for suspending a device (13) provided with fastening elements (19) from a ceiling or a similar substantially horizontal surface (2), comprising a mounting (1) which is adapted to be attached to the ceiling (2) and to a pillar (4) whose one end is connected to the mounting (1) and whose other end is connected to a mounting plate (5), which is adapted to be releasably mounted on said device (13) by means of its fastening elements (19), wherein the column also comprises at least two supporting arms (14, 15) each having an elongate opening configuration (17, 18) which extends in the longitudinal direction of the supporting arms (14, 15), that each supporting arm (14, 15) is movably supported by the mounting plate (5) by means of a separate pin element (16) which is fastened to the mounting plate (5) and which extends through the opening configuration (17, 18), the supporting arms (14, 15) all being pivotable in a plane parallel to the mounting plate (5), and that the fastening elements (19) of said device (13) are received and secured in a portion of the opening configuration (17, 18) arranged at an end of the supporting arm (14, 15) which end projects from the mounting plate (5) and in cooperation with a fastening means (21) and/or by inserting a separate fastening means (21) into the opening configuration (17, 18) for locking engagement with the fastening element (19), the mutual distance between the fastening element (19) and the pin element (16) in the respective supporting arms (14, 15) being adjusted by appropriate positioning of the fastening element (19) and/or the pin element (16) in the opening configuration (17, 18).

2. A column as claimed in claim 1, wherein the opening configuration (17, 18) comprises a slot (17).

3. A column as claimed in claim 1, wherein the opening configuration (17, 18) comprises at least one slot (17) and/or one or more through-holes (18).

4. A column as claimed in claim 1, wherein it comprises extension arms (23) releasably fastened to the supporting arms (14, 15), each extension arm (23) having a through-opening (25, 26) at each end, one opening (25) and said opening configuration (17, 18) receiving a screw joint (24) for connecting the extension arm (23) to the supporting arm (14, 15) and the other opening (26) being intended for receiving and securing said fastening element (19) and/or for inserting a separate fastening means (21) for locking engagement with the fastening element (19).

5. A column as claimed in claim 4, wherein the extension arms (23) have the same design as the supporting arms (14, 15).

6. A column as claimed in claim 1, wherein one end of the pillar (4) is movably fastened (6) to said mounting (1), the pillar (4) being pivotable in a first plane, and that the other, opposite end of the pillar (4) is movably fastened (7) to the mounting plate (5), the mounting plate (5) being pivotable in a second plane which is perpendicular to the first plane.

7. A column as claimed in claim 1, wherein the pillar (4) is telescopic.

8. A column as claimed in claim 1, wherein the pin elements (16) are positioned in the vicinity of the periphery of the mounting plate (5) and are substantially equidistantly spaced apart.

9. A column as claimed in claim 1, wherein it comprises a pair of elongate, cooperating cover halves (28, 28), which are adapted to be attached to each other and surround the pillar (4) and which extend substantially from the mounting (1) to the mounting plate (5).

10. A column as claimed in claim 9, wherein the pillar (4) has means (29) for holding cabling (27) to said device (13) on the pillar (4), encased by the cover halves (28, 28).

11. A column as claimed in claim 2, wherein it comprises extension arms (23) releasably fastened to the supporting arms (14, 15), each extension arm (23) having a through-opening (25, 26) at each end, one opening (25) and said opening configuration (17, 18) receiving a screw joint (24) for connecting the extension arm (23) to the supporting arm (14, 15) and the other opening (26) being intended for receiving and securing said fastening element (19) and/or for inserting a separate fastening means (21) for locking engagement with the fastening element (19).

12. A column as claimed in claim 3, wherein it comprises extension arms (23) releasably fastened to the supporting arms (14, 15), each extension arm (23) having a through-opening (25, 26) at each end, one opening (25) and said opening configuration (17, 18) receiving a screw joint (24) for connecting the extension arm (23) to the supporting arm (14, 15) and the other opening (26) being intended for receiving and securing said fastening element (19) and/or for inserting a separate fastening means (21) for locking engagement with the fastening element (19).

13. A column as claimed in claim 2, wherein one end of the pillar (4) is movably fastened (6) to said mounting (1), the pillar (4) being pivotable in a first plane, and that the other, opposite end of the pillar (4) is movably fastened (7) to the mounting plate (5), the mounting plate (5) being pivotable in a second plane which is perpendicular to the first plane.

14. A column as claimed in claim 3, wherein one end of the pillar (4) is movably fastened (6) to said mounting (1), the pillar (4) being pivotable in a first plane, and that the other, opposite end of the pillar (4) is movably fastened (7) to the mounting plate (5), the mounting plate (5) being pivotable in a second plane which is perpendicular to the first plane.
