Description
SPECIFICATION
Color filter for wind-up system color changer
This invention relates to a color filter for wind-up system color changer, more particularly to a color filter for wind-up system color changer which makes it possible to develop a variety of color scenes and is extremely easy in manufacturing.
On stages or in television studios, colorful color scenes are presented by use of a color changer in order to emphasize the performance effect of the dramas, actions, etc., performed there.
As the color changer used, a variety of kinds of machines have been known and among them, there is, for example, a wind-up system color changer.
Such a color changer usually consists of a projection lamp and a color filter housing box mounted ahead thereof. And, on the both left and right ends internally of the housing box, rotatory rolls are provided, respectively, with the color filters being scanned between the both rolls in the form of winding up the color filters wound up on one rotatory roll onto the other.
The color filter used in such a kind of machine is a light-transmissive film in continuous length. And the color filter is manufactured by plastering continuously the filter units with various colors in the lateral direction (scanning direction) with the use of, for example, a transparent tacky tape. Accordingly, in the case of this color filter, the connecting portion between the respective filter units necessarily has a structure plastered with a transparent tacky tape.
In the case of the color filter of the prior art as described above, the working of connecting the filter units is not necessarily easy. This is because the respective filter units are arranged in the predetermined order on a working stand and the connecting ends between the respective units are plastered with a tacky tape with a care so that they may not be slipped out of place. Also, when the filter unit has a singular shape such as a circuiar shape or a triangle shape, a transparent film in continuous length with a predetermined width is cut at the predetermined portions into shapes corresponding to these singular shapes, and the connecting portions are plastered under the state where singular filter units are fitted therein. Hence such a working requires a considerable skill of an expert.
Further, during usage of the color filter over a prolonged term, the tacky tape having plastered the respective color filter units may be sometimes peeled off.
An object of the present invention is to provide a color filter with a novel structure which can solve the problems as described above and of which color filter can be manufactured extremely easily and makes it possible to develop a variety of color scenes and further has a prolonged lifetime.
The color filter for wind-up system color changer of the present invention has a structure which is a color filter having two sheets of laminated transparent films in continuous length, having a plural sheet of color filter units sealed between the films in continuous length.
In the accompanying drawings:
Figure 1 is an exploded perspective view of a color filter of the present invention; and
Figure 2 is its plan view of the color filter of the present invention.
DESCRIPTION OF THE PREFERRED EMBODI
MENTS
Referring now to the drawings, the color filter of the present invention is described in more detail. Fig. 1 is an exploded perspective view showing the positional relationships between the respective elements of the color filter of the present invention.
In Fig. 1, reference numerals 1 and 1' are transparent films in continuous length having predetermined width and length, and adhesive layers are formed by coating on the opposed surfaces of the both films. Each of 2a to 2e, etc. is a color filter unit. These units, consisting of transparent color film of optional color and shapes, are arranged between the aforesaid films 1 and 1' in continuous length, and sealed and fixed between the both films 1 and 1' by laminating the films in continuous length according to the ordinary methods. Adhering may be carried out by other means such as welding or solvent welding.
This state is shown as a plan view in Fig.
2. As is apparent from the drawings, two sheets of films 1 and 1' in continuous length are firmly adhered between the respective color filter units and/or at the gap portion 1a existing in each end, the respective color filter units 2a to 2e are sealed between the films in continuous length in the state of being interposed therebetween as a whole.
As is apparent from the above description, the color filter of the present invention makes it possible to produce the desired color filter unit by interposing them between transparent laminated sheets. Therefore, it has taken effects that (1) color filter units of a variety of shapes can extremely easily be interposed, whereby various color scenes may possibly be obtained, and also (2) since such color filter units are sealed between the films in continuous length, there is no fear of peeling off tacky tapes which will become the problem when using them, whereby the use life as a filter can extremely be prolonged. Further, even when the color filter was wound-up, no loosening or sagging is occurred. As can been seen from the above, practical vaiue of the color filter units of this invention is extremely great.
