Description

[Detailed description of the invention] (Industrial application field) This invention is used for display decoration lights and neon signs that are attached to glass surfaces such as store windows, or for braking devices that are attached to back windows and side windows of automobiles. It relates to light-emitting display bodies used in lamps, decorative lights, etc.

(Prior Art) The present applicant proposed such a light-emitting display by arranging a large number of light-emitting elements in a row and connecting them to a plurality of conductive wires, and using a flexible display with at least the light-emitting surface side transparent. Various types of bendable light-emitting displays have already been proposed which are entirely encapsulated with an envelope.

These light-emitting displays can be bent in any direction,
Although this is a convenient tool that allows complex bending to be performed freely, there are still some points that need to be improved, such as the following.

(Problems to be Solved by the Invention) That is, since the above-mentioned light-emitting display hardly causes permanent deformation when bent, it is difficult to maintain its bent shape even if it is bent. Therefore, the first
As shown in FIG. 0, when manufacturing a heart-shaped decorative lamp using the light emitting display 100, a large number of fasteners 101 are used to hold the light emitting display 100 in a heart shape. Display body 100
Each part must be fixed to the back windshield 50 of the automobile (or a support plate, a wall surface, etc.), and the fixing work using this large number of fasteners 101 is quite troublesome, and it is difficult to attach the parts directly to the glass surface. Fastening is almost impossible, and a mounting portion must be formed on the glass 50 surface in advance.

The present invention was devised to solve this problem, and allows the backwind to be bent into an arbitrary shape and maintain that bent shape without requiring a large number of fasteners or attachment parts as described above. It is an object of the present invention to provide a light-emitting display that can be attached to glass or the like extremely simply and efficiently.

(Means for Solving the Problems) Therefore, the present invention is a fixture for a light-emitting display body, which has a large number of light-emitting elements arranged in a transparent, bendable, rod-shaped resin flexible envelope. forming a circular concave hole in either one of the surface of the flexible envelope and the back surface of the suction cup, and forming a cylindrical protrusion that fits and locks in the circular concave hole in the other; Or
A holder body is inserted into a suitable position of the flexible envelope, and a circular concave hole is formed in one of the holder body and the back surface of the suction cup, and the other side has a cylindrical shape that fits and locks into the circular concave hole. The gist is that a protrusion is formed so that a suction cup is rotatably supported by the light emitting display via the circular recessed hole and the cylindrical protrusion.

(Function) With such a configuration, when the light-emitting display is bent into an arbitrary shape such as a heart shape, this bent shape is maintained by suction to the glass surface of the suction cup. This is prevented by adsorption to the surface, making it possible to maintain the shape of the light-emitting display in an arbitrary bent shape.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is a plan view showing an example of a light emitting display;

can be absorbed and relaxed. This conductive wire 21,
The elongation absorption/relaxation acting on 22 is not limited to this structure, and may have any structure.

A light-emitting display A is formed by enclosing these light-emitting elements 1 and conductive wires 21 and 22 with a flexible envelope 3 such that the rows of light-emitting elements 1 are located along the center line. There is. The flexible envelope 3 is made of soft polyvinyl chloride resin, acrylic resin, polyethylene resin, polycarbonate resin, silicone rubber, etc., and has a flexible rod shape with a circular or square cross section, and has translucency as a whole. It is preferably configured to have light diffusing properties by containing a light diffusing agent, and the side opposite to the light emitting surface is made of a resin mixed with a light reflecting agent such as aluminum flakes, or by metal vapor deposition. A reflective layer 31 is formed. The flexible envelope 3 may be made of colored semi-transparent resin to enhance the display effect.

Therefore, the present invention provides a holder main body 4 having a circular through hole 41 in a light emitting display body A having the above-described structure.
A suction cup 5 is supported through the suction cup 5, and the light-emitting display body A is attached to a back window glass of a car, a shop window glass, etc. using the suction cup 5.

The holder main body 4 is preferably made of transparent synthetic resin, and has a receiving part 42 having a circular recessed hole 43 formed on the outer circumference of the main body 4, and an annular groove formed on the inner peripheral surface of the circular recessed hole 43. A rib 44 is formed to protrude. The central axis of the circular concave hole 43 is perpendicular to the central axis of the through hole 41.
Further, as shown in FIG. 5, the holder main body 4 can be opened and closed by separating it at the opposite side from the receiving part 42.
