Definitions

  • the present invention relates to a display means with adjustment possibility for the screen.
  • the patent document US 4, 700, 498 relates to a portable display apparatus, although not a so called roll-up display.
  • the display area can be tilted forward or rearward by adjusting the length of two vertical support members 28. This is made possible because each support member 28 is telescopic.
  • the patent document EP 0 969 442 A1 relates to a support which comprises a number of pieces which can be attached to each other and is designed for holding one or two advertising posters by the upper and lower ends, keeping them in substantially vertical position.
  • This support includes a supporting base composed of two sides attached to each other by means of detachable crosspieces; each one the sides has tensioners to act upon the lower ends of one or two posters, intermediate seats for mounting flexible structures, which are independent and finished at the top in two pieces for hanging the posters, means for fitting one or more tensioning cables which act upon the pieces, keeping the structures flexed and ensuring that the pieces are held at the desired height, in function of the height of the posters to be displayed.
  • the structures are composed of a variable number of sections, of equal length, which are joined by intermediate connecting pieces, while the height of said structures can be adjusted by attachment of a greater or lesser number of sections. It is pointed out that this support is not a so called roll-up display.
  • the document DE 299 13 949 U1 relates to a display means, although not a so called roll-up display.
  • the display means is provided with three feet, which are adjustable in order to compensate for a floor which is uneven.
  • the patent document US 2007/0002440 A1 relates to a portable screen assembly which can be readily transported together with a projector and is easy to handle and simple in construction.
  • the portable screen assembly includes a casing having an opening extending in a longitudinal direction on the upper surface thereof and formed by a first and second case members that extend in the longitudinal direction and are separable from each other, a spring-biased roll rotatable mounted to the casing, a screen wound around the spring-biased roll in storage and pulled out from the opening in use, a top bar fixed to one end of the screen and used also as a cover body to close the opening in storage, and an extendable column having one end erectable pivoted at a center part of the side face of the casing and, in an erected state, holding the pulled out screen in a stretched state.
  • the appearance of a graphic presentation is best if the screen or the printed panel is positioned in a vertical position.
  • One problem arises when the product is put on a floor that is uneven.
  • Another problem arises when the height of the telescopic pole is increased, making the screen/panel tilt forward as the center of gravity changes. Attaching a spotlight at the top of the display means will also make the screen/panel tilt forward due to the fact that the centre of gravity changes.
  • the display means comprises a stand adapted to secure a screen, wherein the stand comprises a first part which supports against an underlying supportive surface and comprises a bobbin enclosed in a cavity in the first part.
  • the screen can be wounded onto and withdrawn from the bobbin.
  • the stand also comprises a pole means, and a coupling means arranged at a first end of the pole means and operable to secure the screen when it is at least partly withdrawn from the bobbin.
  • the first part is provided with a recess operable to receive a part of the pole means comprising a second end of the pole means, or to receive a lever means partly arranged in the pole means.
  • the stand also comprises an adjustment means arranged at the first part, and operable to directly adjust the pole means, or indirectly adjust the pole means via the lever means, and consequently the screen in relation to the first part.
  • an adjustment means arranged at the first part, and operable to directly adjust the pole means, or indirectly adjust the pole means via the lever means, and consequently the screen in relation to the first part.
  • the stand also comprises a pole cup means arranged in the first part, and adapted to receive the pole means.
  • pole cup means is provided with an aperture.
  • a further advantage in this context is achieved if the first part is provided with a through hole having an internal thread, and if the adjustment means is in the form of a rod having an external thread, and an operating means connected to the rod.
  • the internal and external threads are mating each other, and the rod is abutting the pole cup means.
  • the operating means is operable to being turned, adjusting the pole cup means, the pole means, and the screen.
  • the first part is provided with a through hole having an internal thread, wherein the through hole and the aperture at least partly are coinciding, and if the adjustment means is in the form of a rod having an external thread, and an operating means connected to the rod.
  • the internal and external threads are mating each other, and the rod is abutting the pole means, or the lever means.
  • the operating means is operable to being turned, directly adjusting the pole means, or indirectly adjusting the pole means via the lever means, and the screen.
  • the first part is provided with a through aperture adapted to receive the adjustment means, and if the adjustment means is in the form of a cam disc means, and a cam shaft.
  • the cam shaft is connected to the first part, and arranged through the cam disc means in such a way that the cam disc means is operable to be at least partly rotated around the cam shaft.
  • the cam disc means comprises a cam surface at least partly abutting the pole cup means, and an operating part protruding from the first part.
  • the operating part is operable to being operated, at least partly rotating the cam disc means around the cam shaft, adjusting the pole cup means, the pole means, and the screen.
