Abstract
The invention relates to a support for articles such as ceiling slabs, roof battens, machine parts or the like. The support comprises at least two telescopic tubes or one telescopic eod in at least one tube. A first tube or the rod can be displaced by a first distance in relation to the second tube, and devices are provided to convey the first tube or the rod a further distance in relation to the second tube. Stopping devices for the tube(s) and the rod are also provided in relation to each other and end stops are provided on the tubes, or the rod, the devices for further conveyance of the first tube or the rod comprising a ratchet, rack, clamping bracket or the like which are provided with manual advance devices.
Claims16
A holder comprising:
- at least two telescoping pipes, wherein a first pipe of the two telescoping pipes is movable a first distance relative to a second pipe of the two telescoping pipes;
- transport means for moving the first pipe relative to the second pipe the first distance, wherein the transport means comprises a spring connected to the first pipe and the second pipe for transporting the first pipe relative to the second pipe, and wherein the spring is aligned with an axis of the second pipe;
- and the holder further comprising
- advancing means for moving the first pipe a further distance relative to the second pipe.

A holder comprising:
- at least two telescoping pipes, wherein a first pipe and a second pipe of the at least two telescoping pipes have respective upper ends, the second pipe has a lower end, and the first pipe is shiftable in relation to the second pipe by a first distance;
- a transport device for transporting the first pipe in relation to the second pipe by the first distance;
- and
- an advancing device for moving the second pipe a further distance relative to the first pipe, wherein the advancing device includes:
