Definitions

  • the invention relates to a projection furniture, in the body of several devices, including at least one camera and a projector, are, and these devices are completely put into operation by unfolding the furniture or pulling out drawers.
  • the font EP 1482739 A1 introduces a combination of projector and digital camera with one control. By projecting text or image templates over a large area, you can achieve good magnification without losing track of the overall picture.
  • the invention proposes a tripod for the camera and for the projector before a ceiling mounting, ie its position is not readily variable. When not in use, the devices must remain where they may be in the way, dust, or visually disturbing. If the devices are removed, they must be realigned before the next use.
  • magnification devices are mainly used in the commercially available screen readers used. These combine a camera with a monitor, on which the recorded images are displayed, possibly after editing for contrast enhancement or similar.
  • a disadvantage of these devices is that Due to the required high magnification and the limited area of the monitor only a relatively small image detail can be considered. This makes it difficult, for example, to keep track of in a newspaper text, and the template must be constantly moved under the camera.
  • the known projection furniture can be placed next to a seat so that a visually impaired person can place pictures and documents under a camera on a fold-out work table and view them in a greatly enlarged projection on an opposite surface, in the simplest case a bright wall of the room ,
  • This feature is now enhanced by attaching the camera to a mounting plate with a pivoting arm, which is slidably mounted under the upper cover plate of the carcass. Due to the flexible mounting and positioning of the camera, the various positions of the user can be taken into account.
  • Documents can be placed on a workbench folded out to the side and then projected onto a projection screen.
  • the worktable can be illuminated with lights.
  • templates can be recorded on a table next to the projection furniture with the camera and projected.
  • the camera can be adjusted to the most different working heights above the respective table surface. It is also possible to record objects with the camera that are not horizontal on a table surface.
  • the camera is attached to a pivot arm with a pivot on the support plate, which in turn is slidably mounted under the upper cover plate of the body.
  • the camera is preferably equipped with an autofocus function that also adjusts the zoom factor.
  • the body in the closed state is cuboid, about 100 cm high and with a square base area of about 45 x 45 cm. It consists of a matching material to other furniture and is stored on wheels, so that it fits easily into the existing furnishings of a room. All technical devices are located inside the body and are put into operation when they are opened, without the need for further steps to switch on or operate.
  • the projector and possibly other devices are arranged in the lower region of the carcass behind front and rear doors, with at least the projector is located on a drawer.
  • these devices When opening the front door or pulling out the drawer with the projector, these devices turn on automatically and the projector is also operating without any additional operating steps.
  • All devices, as well as possibly in the body built-in speakers and work table lighting have a common power supply, so that only a cable outside the furniture is to be laid, which can also be stowed when not in use inside the furniture.
  • a work table can be folded out of the body, which can also be provided with a luminous surface to project transparent templates, such as slides.
  • a double plate is preferably provided, the inner end is extended so far that it strikes in the closed state to the body and the open state of a drawer and thus keeps the work table in position.
  • Fig. 1 the projection furniture according to the invention is shown in a room with a projection surface 17. This area is here a permanently installed extendable projection screen.
  • the person 16 using the furniture sits in front of the unfolded work table 2
  • An auto-focus camera 9 fixed to the cover plate 4 receives the surface of the work table; the image is thrown by a located in the body 1 of the furniture, not shown here projector with a significant magnification factor on the wall.
  • Fig. 2 shows the projection furniture with its furniture body 1.
  • a cover plate 4 on which the camera arm 7 is mounted with the sliding and pivoting camera 9.
  • the hinged surfaces, so the door 5 and the work table 2 are flush with the body 1, so that there is a uniform cuboid shape with a few grooves.
  • the projector 10 and possibly other devices such as a computer 12 are housed next to the camera 9.
  • a luminous surface 18 is still attached, by means of which translucent objects, such as films, can be projected.
  • Fig. 3 is the projection furniture with an additional table to see 11, on which there may be templates to be projected.
  • the camera 9 is positioned with its swivel arm 7 above the table 11.
  • the arranged on an extendable drawer 6 projector projects the image above the table surface and is thus not affected by the table 11.
  • the work table 2 with the luminous surface 18 is not needed in such a situation.
  • Fig. 4 shows the projection cabinet 1 in a side section in a normal work situation.
  • Derb body is provided with wheels 8, so that it can be easily driven to the desired place.
  • the work table 2 is opened and a template on the luminous surface 18 is projected with the camera 9 positioned thereon by means of the projector 10.
  • the camera 9 is held with its pivot arm 7 on the displaceable camera holding plate 3, which in turn is slidably mounted on the cover plate 4.
  • the work table 2 is provided with a double plate 13, which strikes in the working position under the drawer 6 of the projector. Once the camera 9 is stowed in the body 1, the work table 2 is folded up and the double plate 13 strikes the body 1, which is indicated by the dashed line.
  • Fig. 5 schematically the possibilities of positioning the camera 9 are shown.
  • the camera 9 is held on the pivot arm 7, which holds the camera 9 in the vertical position by means of a parallelogram transmission.
  • the pivot arm can be moved up and down about the pivot joint 15.
  • a counterweight 14 is accommodated in the swivel arm 7.
  • pivot arm 7 can also be rotated in the pivot joint 15.
  • the pivot joint 15 is fixed to the camera holding plate 3, which in turn is slidably mounted on the cover plate 4.
