Abstract

The present invention provides a multi-faced reflector that is compact, lightweight, beautiful, has a decorative effect, and has excellent portability that can strongly reflect external light from many directions.
An outer peripheral frame 6 is provided on the back surface of a colorless or light colored rectangular transparent plastic plate, and a triangular pyramid 10 and six small triangular pyramids 13 surrounding the outer peripheral frame 6 are arranged in a plane at predetermined intervals. A first half 2 having a light-scattering surface, and a second half 3 having the same configuration with the positions of the first half 2 and the triangular pyramid and the small triangle pyramid of the first half not being opposed to each other. Are held together with a gap d that does not contact each cone surface on the back of each half body, and the outer peripheral side portions are bonded or fused to be integrated.

Description

  The present invention relates to a transparent plastic multi-surface reflector suitable for portable accessories and the like.

Plastic reflectors that are used as decorations to be attached to night display bodies and portable items of automobile bodies are rectangles of about 20 to 60 mm x 60 to 100 mm and are inconvenient to carry. However, there is a drawback that the reflection display effect is not sufficient only by reflecting light from one direction.

The conventional plastic reflector has a large number of triangular pyramids protruding from the back surface of the transparent plastic plate and is regularly arranged so that each triangular pyramid is surrounded by six small triangular pyramids, Such transparent plastic reflectors themselves are described in Patent Documents 1 and 2, for example.

  This proposal is to provide a multi-faced reflector that is compact and enhances portability, and emits strong reflected and scattered light against externally irradiated light from various directions.

The configuration of the polyhedral reflector of the present plan is that a rectangular transparent plastic plate having a smooth surface is provided on the back surface with an outer peripheral frame, and a triangular pyramid and six small triangular pyramids surrounding the triangular pyramid are arranged in a plane at a predetermined interval. A second half having the same configuration, with the first half having a light scattering surface disposed in the first half and the triangular pyramid and the small triangular pyramid of the first half leaning together so as not to face each other. It consists of a half body, holds the gap to the extent that each cone surface of each half body does not contact, faces each other, and bonds or fuses the outer peripheral side parts and integrates a protrusion with a string through hole on one side It is provided.
The first and second halves are highly transparent, for example, colorless or light colored plastic rectangular bodies made of acrylic resin, and the outer peripheral frame also serves as a joint surface and a face-to-face spacing holder. The light scattering surface composed of the triangular pyramids and the small triangular pyramids of the first and second halves forms a strong reflection surface, and reflects irradiation light from multiple directions. Further, by forming a slope on the peripheral edge of the smooth surface, the reflective surface increases, a more beautiful appearance is obtained, and the first and second halves are colorless or the same color, and the decorative effect is achieved by a combination of different colors. Can be increased.

In the present reflector, the positions of a large number of triangular pyramids constituting the back surface of the half body are made to face each other. The display effect is high with respect to the irradiation light from the outer periphery and the display effect is high, and a beautiful decoration effect is also obtained. Moreover, since it is small and lightweight, it does not feel uncomfortable even if it is carried, and it can be used as a mark switch for a string switch in addition to a base of base and a reflective amulet.

1 and 2, reference numeral 1 denotes a reflector of the present invention, 2 denotes a first half, and 3 denotes a second half, which is a rectangular transparent acrylic resin molded body having a size of about 20 mm × 30 mm. Reference numeral 4 denotes a smooth surface, and slopes 4A for enhancing the reflection effect are formed on three sides.
Reference numeral 5 denotes an outer surface, and reference numeral 6 denotes a frame portion serving as a joint surface. The frame portion also serves as a spacer that holds a facing distance d described later. 7 is a back surface constituting the light scattering surface, 8 is an attaching projection such as a string, and 9 is a string hole.
The configuration of the light scattering surface is as shown in FIG. 3, and a large number of triangular pyramids 10 are projected on the back surface of each half body at predetermined positions, and six small triangular pyramids 13 surround the periphery. It arrange | positions so that it may be arranged in a planar shape. 11 is the top of the triangular pyramid, 12 is the slope, 13 is the surrounding small triangular pyramid, 14 is the top, and 15 is the slope.

As shown in FIG. 4, the reflector of the present invention is held at a distance d of 0.5 to 1.0 mm so that the slopes 12 and 15 of the triangular pyramids 10 and the small triangular pyramids 13 of the first and second halves do not contact each other. Facing each other, the joining surfaces 7 of the respective half bodies are joined together by an adhesive or high-frequency welding to be integrated.
