Brief Description Of Drawings
In conjunction with relevant drawings, by the detailed description of preferably following but not limited specific embodiment, the present invention will be easier to understand.Wherein:
Fig. 1 represents the preferred embodiment of display device, and it has the xsect that is generally triangular, and three discontinuous display surfaces are used for showing each display surface in the angle of the best, and can be arranged on position near ceiling structure at its stop position;
Fig. 2 is illustrated in how to suppress demonstration in the display device;
Fig. 3 represent according to of the present invention one optionally, also be the embodiment of preferred display device;
Fig. 4 represents that one also is the embodiment of preferred display surface optionally, and it changes into and being installed on floor, ground or other substrate; And
Fig. 5 represents the viewing angle of the optimum of display device.
Embodiment
In the accompanying drawings, unless specifically stated otherwise, the parts that identical numeral is same.
As shown in FIG., display device represents to have rotatable frame body with numeral 1 usually, represents with numeral 2 usually, is suitable for around central shaft 3 rotations.Axle 3 is connected on the ceiling 5 by suitable framed structure 4.Optionally, equipment also can comprise wall, floor or other surface by other support, and the back will be described in conjunction with Fig. 4.
The first embodiment of the present invention as shown in the figure, is used to show the translite displays of a plurality of static state.In this embodiment, provide a lighting device, in rotatable frame body, be connected, with fluorescent tube 6 and reflection unit 7 expressions with framed structure 4.Also can adopt other lighting device, for example LED.Lighting device is arranged in the rotatable framework 2 in the mode of static state, makes that having only a display surface to be illuminated is used for showing.In equipment shown in Figure 1, display surface 8 is illuminated by lighting device 6,7, and does not illuminate the display surface 9,10 that is not used to show.This can reach and both save the illumination loss by reducing the required quantity of lighting device, saves power consumption again.
In addition, or alternatively, can dynamically show that this can obtain by the demonstration of using plasma, LCD, back projection or dynamic-form from one or more display surfaces.
The display device that Fig. 1 represents also can be in conjunction with cam face 11 and the ball bearing cam follower 12 with corresponding bias unit or spring 13, and it and rotatable framework 2 integral body form or are connected on the framework.Therefore, rotatable framework 2 can stop at discontinuous stop position effectively.Ball bearing cam follower 12 also is used to control the height of rotatable display device 1 apart from ceiling 5, makes described display device 1 select one of display surface 8,9 and 10 rotatably.That is, allow display device 1 during display surface 8,9,10 rotations, to dip, so that showing more clearly of above-mentioned relatively ceiling to be provided, simultaneously in above-mentioned stop position reorientation with near ceiling.
As shown in Figure 5, this equipment can optimum viewing angle show the menu system that is arranged in the restaurant that quick room service is provided.This angle can be about 20 ° (from vertical) usually, but also can change, and between for example about 10 ° to 50 °, changes according to specific installation.
The embodiment that represents among the figure has shown three display surfaces, and each slightly arc or crooked shape wherein is with the form configuration of triangle xsect.Yet, clearly, can form the display surface of any number, for example, 2,3,4,5,6 etc.Apparently, will determine suitable cam contour 11 or swivel bearing 16 according to the outer shape of display device and the number of display surface.
Fig. 2 represents how light transmission piece covers or be supported on each display surface.Illustrated embodiment is represented the display surface 8 of the prebuckling backboard made by polypropylene or similar material, and these materials are suitable for extruding and crookedly block a shot between the part 14 in terminal extrusion 15 and terminal.Light transmission piece or other flexible and transparent sheet shaped piece with suitable advertisement or mark, can be inserted into and remain between display surface 8 and the terminal extrusion 15, and, perhaps keep by other suitable coupling arrangement because the display surface 8 of prebuckling returns to its original shape and maintains in this position.
Coupling arrangement selectively applied magnetic material is connected on the light transmission piece, can instead perhaps also can adopt clip.This can be by being connected to display surface with one or more magnetic poles, and another or some magnetic poles are connected to light transmission piece, and two magnetic poles are attracted each other, thereby realize light transmission piece is remained to display surface.
The embodiment that Fig. 3 represents uses cam face 11 except replacement, and adopts the swivel bearing 16 that preferably is connected with self locating device, to be applicable to display device 1 is found outside its discontinuous stop position, and is identical with previously described embodiment.
Within spiritual scope of the present invention, can consider other embodiment, comprise that the applied magnetic material constitutes alignment device, so that display device finds its discontinuous stop position.This can realize that like this, in specific interval, attraction is to form the discontinuous stop position of rotatable framework by arrangement of magnets on axle and rotatable framework.Can add or use alternatively the magnet of opposite polarity so that rotatable framework resists the centre position between the discontinuous stop position.The difference of magnet is arranged can realize that this function is obvious for those skilled in the art.
The embodiment of Fig. 4 is also similar with previously described embodiment, just is suitable on the substrate surface of the equipment of being supported on one headwall wall.Clearly, according to this set, display is mounted to vertical with the configuration among Fig. 1 to 3.Clearly, other configuration also is possible, for example is connected on the wall a vertical position, in conjunction with floor and wall supports etc.
Clearly, can make preparations for sowing different variations and modification of the front display device having described and demonstrated in the accompanying drawings.These all variations and modification will be considered to drop on the present invention within the scope of extensively describing before this and being stated in claim after this.
