Patent ID: 8590188

Claim:
An information presenting device, which device is arranged to be capable of assuming a first configuration, in which the device is flattened for transport or storage, and of assuming a second configuration, in which the device is extended and hence self-supporting, said device comprising: at least two panels, made of a rigid material, which are joined together along the respective edges of at least two of the panels such that the device, having assumed the second configuration, forms a hollow cylinder, wherein at least one locking member is arranged between said panels for continuously adjustable locking of the device in at least said first and second configuration, respectively, the locking member comprising a first part and a second part, the first part being slidably connected to the second part and the locking member being self-locking by a friction band coupling formed between contact surfaces of the first part and the second part of the locking member, wherein the device does not comprise a pretensioned tensioning element that biases the panels to the second configuration and that must be overcome in order to obtain the first configuration; and wherein the at least one locking member is fastened to an inside of the device at two separate fastening portions.
