  • Patent number: 9069239
    Abstract: A collapsible display device includes a stand that includes a first part that supports against an underlying supportive surface, and a pole having a first end removably secured in said first part. The display device includes an essentially rectangular screen to be assembled to and disassembled from the display device and a first coupling arranged at a second end of said pole to cooperate with a second coupling arranged at a first short end of said screen. The first part includes at least one first fastener arranged at a shorter distance to the supportive surface than an at least one projector. The screen includes at least one second fastener arranged at a second short end to magnetically fasten to the at least one first fastener, a first magnetic strip arranged in connection with a first longitudinal end, and a second magnetic strip arranged at a second longitudinal end.

  • Patent number: 8807193
    Abstract: A collapsible, flexible display system for creating different spatial shapes of a continuous screen includes at least two stands, each including a first part which support against an underlying supportive surface and a pole with a first end removably secured in the first part by a second coupling and a second end provided with a first coupling. The display system also includes essentially hollow, straight members of a rigid material including first and second end parts, and essentially hollow, bendable members of a flexible material including first and second end parts. Each end part includes either a male part, or a female part, at least one of them of a magnetic material, and operable to magnetically fasten to each other. Straight members and bendable members are connected to each other to form an upper part and a lower part.

  • Patent number: 8615914
    Abstract: The present invention relates to a collapsible display-arrangement (A; B) having a base unit (2) for placing against a support surface (1), a sheet (4) that can be rolled up or unrolled and on which a picture and/or text appears, and also a support (3) for retaining the sheet, the upper edge (4a) of the sheet being arranged for co-operation with said support (3). At least one end part of said upper edge (4a) is designed to be able to be provided with a permanent magnet (7) or the like, and the magnetisation direction or directions is/are so chosen that an attractive force will operate between said permanent magnet (7) and a permanent magnet (7a?) pertaining to an adjacent display arrangement (B).

  • Patent number: 8028449
    Abstract: A collapsible display arrangement has a base unit for placing against and resting the collapsible display arrangement upon a support surface with a sheet formed from a rollable material. The sheet is rolled or unrolled and has an image. The collapsible display arrangement has a first rod as a support for cooperating with the base unit and for retaining the sheet in an exposed state with the sheet in the exposed state having an upper edge section, a first lateral edge section, and a second lateral edge section. The upper edge section is supported by a second rod provided with end related permanent magnets. Each magnet is oriented and has a magnetization direction and each has an attractive force that will operate between the permanent magnet and an adjacent second oriented permanent magnet. The second permanent magnet is connected to an adjacent second display arrangement, and each of permanent magnet has a magnetization direction causing an attractive force to the second oriented permanent magnet.
