DESCRIPTION:
BRIEF SUMMARY
This invention relates to a buildable device for receiving essentially planar, preferably graphic products in accordance to what is stated in the introductory clause of claim 1.
The device can be charged with different kinds of pictures, advertising text, information data or similar being suitable for various occasions as trade fairs, exhibitions, advertising displays and the like. It can also be used for screening and subdividing office rooms and the like, in which case, for instance, a sound absorbing board can be mounted in the device. The device is furthermore simple to mount and dismount, i.e. solely by means of only a low number of simple manipulations. The device can be carried by one person in a mounted condition.
Stands for receiving pictures are known which for instance include eight frames arranged in two superposed rows with four frames in each row. The frames are sidewardly interconnected by means of hinges in such a way that they can be folded in both directions along a vertical axis between the frames so that they engage each other with their largest sides, these hinges being known per se. The outermost frame at one end of the upper row is hingedly connected with the outermost frame in the corresponding end of the lower row. The other frames in the upper row are releasably connected to the corresponding frame in the lower row by means of snap-action type locks. When the picture stand is to be folded, the interconnected rows are first folded as a unit. The snap-action locks are then disconnected and the folded upper row is folded downwards, towards the folded lower row. Each frame according to the prior art consists of four profiled mouldings arranged in a rectangle, each moulding having two grooves being arranged parallel in respect to each other with a medial flange extending between the grooves giving the frame rigidity. The upper profiled mouldings of the frames in the upper row and the lower profiled mouldings of the frames in the lower row can be opened in a way that two pictures can be inserted into the circumferential grooves formed by the three remaining profiled mouldings in the frame.
U.S. Pat. No. 1,282,685 discloses a foldable screen for screening or subdividing for instance a room. The screen includes a number of sections in an upper and a lower row, a main section in the upper row being hingedly connected to a main section in the lower row and the sections in the upper row being hingedly interconnected, as is the case with the sections in the lower row.
U.S. Pat. No. Re. 30,777, Oct. 20, 1981 discloses a development of the foldable picture stand according to the above mentioned American patent specification having eight frames arranged in an upper and in a lower row. The frames are hingedly interconnected by means of hinges in such a way that the stand can be folded. In each frame, pictures can be inserted into grooves in the mouldings forming the frames.
U.S. Pat. No. 3,514,886 and 3,882,974 both disclose frames for the insertion of pictures. The frames are constructed of profiled mouldings having longitudinal grooves facing the center of the frame. When a picture is to be applied in the frame, one of the four profiled mouldings are removed and the picture is inserted into the frame.
There are several disadvantages associated with the above-mentioned prior art picture stands.
Firstly, there are problems when they are to be charged, since the pictures, for practical reasons, only can be inserted into the grooves in the profiled mouldings of the frames when the picture stand is in its mounted condition. Because of this it is difficult to ensure that all pictures are in their right place and are facing the right way. In addition to this, if the places of some pictures are to be changed or if a picture is to be changed, the entire screen must be mounted before this can be done.
Secondly, the joints between the different pictures in the picture stand are too wide. This is on one hand due to the space between the frames, and on the other hand due to the fact that the flanges of the
