Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable reflector used for taking a photograph or a movie, a slide, a projection screen for a movie or the like, a back of a subject for taking a photograph, and various other uses. The present invention relates to a work board for portable light reflection and the like.

[0002]

2. Description of the Related Art Heretofore, as a foldable lighting reflector used for taking a picture, for example, a steel strip is circularly bent around a circular reflector made of a silver paint applied to a cloth surface. It is a circular reflector with the endless circular elastic frame sewn over the entire circumference.When not in use, the circular elastic frame is twisted while resisting elasticity and folded into a three-fold flat state that is convenient for carrying, and when used, There is known a structure in which the folded elastic frame is developed into an original circular plate shape by the elastic restoring force.

However, if the conventional circular reflector as described above has a diameter that can illuminate the upper body of a standing person, for example, it cannot illuminate the whole body (vertical subject) of the person. In such a case, there is an inconvenience in that a large-diameter circular reflector that can illuminate the entire length of the person must be separately prepared.

[0004]

SUMMARY OF THE INVENTION According to the present invention, one circular work plate can be deformed into various shapes such as an oval shape and a substantially rectangular shape in accordance with each work such as a reflection plate, a projection screen, and a back of a subject. It is an object to improve it.

[0005]

As a means for solving the above-mentioned problems, the present invention relates to a work cloth which is formed by stacking a circular work cloth having a working color on a cloth surface on one side of an endless circular elastic frame made of steel strip. The other side of the above-mentioned elastic frame is folded back all around,
An elastic string is used to elastically narrow the folded-back entire peripheral portion in the center direction, and a plurality of portions of the folded-back peripheral portion of the work cloth are pulled substantially to the center to deform the elastic frame into a desired shape. We propose a foldable portable light reflection and other work board with a band.

As the above-mentioned "work cloth" in the present invention, stretchable woven fabrics and knitted fabrics, and further, woven fabrics having poor stretchability are appropriately used. The one using an elastic yarn for one or both of the warp yarn and the weft yarn is used.

The "work color" is applied to one or both sides of the work cloth, and the colors are appropriately selected from white and gold and silver for light reflection, white for projection screen, and various colors for subject back. You.

Further, as the “shape” to be transformed,
Oval, gourd-shaped, substantially square, substantially rectangular, substantially triangular, and the like. Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0009]

1 and 2 show a work plate (1) which can also be used as a reflector and a back of a subject. The work cloth (2) is made of a light-reflective silver paint on one surface of an elastic fabric dyed in gray. A belt-like elastic cord (3), which is appropriately shorter than the entire peripheral length, is sewn as an elastic cord to the entire peripheral portion of the applied circular cloth, whereby the entire peripheral portion of the circular work cloth (2) is slightly squeezed. One end of the deforming band (4) is fixed to one portion of the peripheral portion of the work cloth (2), and a band through hole (5) is formed in the peripheral portion in the diameter direction with respect to the fixing position. It is provided. (6) is a male connector attached to the tip of the band (4), and (7) is a female connector attached to an intermediate portion of the band.

The elastic frame (8) inserted into the work cloth (2) is an endless circular shape formed by bending a steel strip and connecting both ends. In this embodiment, the elastic frame (8) is further provided with a cloth cover (9). ).

[0011] The work cloth (2) is placed on one side of the elastic frame (8) as described above, and the entire periphery of the elastic frame (8) with the elastic cord (3) is covered with the elastic frame (8). The other surface of the elastic frame (8) is folded back, so that the folded whole peripheral portion is squeezed toward the center by pulling the elastic cord (3) as shown in FIG. In this example, the silver surface of the work cloth (2) is shown as a table.

After the work plate (1) is used as a reflector and used to illuminate the upper body of a person in the same manner as before, when the whole body is illuminated next, the distal end of the deforming band (4) must be diametrically oriented. The work cloth (2) is pulled while being folded back through the through hole (5), thereby pulling two opposing portions of the folded back portion of the work cloth (2) toward each other, and the inner circular elastic frame (8) as shown in FIG. The work plate is elastically deformed into an oval shape, and accordingly, the entire work plate is also deformed into an oval shape. In this state, the male connector (6) is locked to the female connector (7).

The use of this oblong reflector makes it easy to illuminate the whole body of a person.

When the work plate (1) of the above example is used for the back of a subject, the male and female connectors (6) and (7) of the band (4) are removed and the work cloth (2) is elastically framed ( 8)
The work cloth (2) is turned over, and then the work cloth (2) is turned over, and the gray surface is placed on the elastic frame (8) in the same manner as described above to form a gray circular work plate (1). Or deformed into an oval shape by a deformation band (4) as shown in FIG.

After use, the connecting members (6) and (7) of the deformation band (4) are removed and the work plate (1) is returned to the circular work plate (1), and folded in a three-fold flat state as shown in FIG. To store.

FIG. 5 shows an example of a work plate (1a) which can also be used as a reflection plate and a projection screen. A work cloth (2a) is made of a circular cloth in which a light-reflective silver paint is applied to one side of a white knitted fabric. The other structure is such that the deformation bands (4a) and (4a) are fastened at two places 90 degrees apart from each other in the peripheral part and the band through holes (5a) and (5a) are provided in the diametrical peripheral part. Are substantially the same as in FIGS. Working plate (1
In the case of a), when the silver surface is used as a table and used as a reflector in a circular shape as shown in FIGS. 1 and 2, or when it is transformed into an oblong shape as shown in FIG. 4 and then used as a projection screen, After the work cloth (2a) is once peeled off from the elastic frame (8a), the work cloth (2a) is turned upside down and attached to the elastic frame (8a) with the white surface facing up, and then as shown in FIG. 4a) is pulled through the corresponding through-holes (5a) and (5a), thereby pulling two sets of two opposing peripheral portions of the work cloth in a direction orthogonal to each other, thereby making the elastic frame (8a) substantially rectangular. , Thereby deforming the entire work plate into a rectangular shape and locking the male and female connectors (6a) and (7a). If this substantially rectangular work plate (1a) is supported on a wall or the like, a screen suitable for projection is obtained.

In addition to the above example, three deforming bands are fixed at equal intervals around the circular work cloth, and the other structure is substantially the same as any of the above examples. In some cases, the circular working plate can be deformed into a substantially triangular shape by pulling the deformed bands toward the center and connecting them to each other at the center position.

[0018]

According to the foldable portable work plate for light reflection or the like of the present invention, one circular work plate can be used as an elliptical shape, a substantially rectangular shape or the like in each work such as a reflector, a projection screen, and a back of a subject. It can be easily deformed into various shapes, so that it can be effectively used in a shape suitable for each application.
