2. Description of the Related Art Conventionally, as shown in FIG. 14, a light source 2 is arranged at one longitudinal end of a light guide 1 formed in a tubular shape (cylindrical shape), and the other longitudinal end of the light guide 1 is arranged. The light guide 1 has a structure in which an end reflector 3 is arranged in a portion of the light guide 1.
It is considered that the illumination is performed by gradually leaking light through the peripheral wall while guiding the light in the longitudinal direction.
As shown in FIG. 15, the light guide 1 has a structure of maximum four layers, and the function of guiding the light from the light source 2 and leaking the light is realized by the prism sheet 11. The prism sheet 11 is made of a transparent synthetic resin such as polycarbonate. As shown in FIG. 16, the prism sheet 11 has irregularities formed on the outer surface in a cross section orthogonal to the longitudinal direction. It is set to 90 degrees. Moreover, the inner side surface is formed smoothly. Therefore, a part of the light passes through the prism sheet 11 and the rest of the light is reflected by the prism sheet 11 according to the incident angle of the light from the inner surface. The prism sheet 11 is usually formed into a cylindrical shape by rolling a flat sheet.

An extractor film 12 made of a white synthetic resin sheet is arranged inside the prism sheet 11 as needed, and the light distribution is controlled according to the position where the extractor film 12 is provided. On the other hand, a reflector film 13 made of a white synthetic resin sheet is arranged on the outside of the prism sheet 11 as required, and the prism sheet 11 is provided at a portion where the reflector film 13 is provided.
The light from is blocked. Further, the outer side of the prism sheet 11 is covered with the outer film 14 over the entire circumference. When the reflector film 13 is provided, the outer film 14 is arranged outside the reflector film 13. The outer film 14 is made of polycarbonate and normally has a cylindrical shape, but a flat plate may be rolled to form a cylindrical shape. The outer film 14 is transparent or milky white and has a function of reinforcing the entire body to maintain strength. When a milky white one is used, it also has a function of diffusing light.

The end reflector 3 is a molded product of aluminum and is fitted to the end of the light guide 1. The surface facing the inside of the light guide 1 is a mirror surface and has a function of reflecting the light from the light guide 1.
The light introduced from the light source 2 into the light guide 1 partially passes through the prism sheet 11 while being repeatedly reflected by the inner peripheral surface of the light guide (prism sheet 11). In the area where the extractor film 12 and the reflector film 13 are not provided, the light that has passed through the prism sheet 11 passes through the outer film 14 and is extracted to the outside. In addition, the light reaching the end reflector 3 is
The light is reflected by the end reflector 3 and returned to the light guide 1, and finally taken out through the prism sheet 11 and the outer film 13. In this way, the light can be extracted from the prism sheet 11 with substantially uniform brightness over substantially the entire length of the light guide 1.

By the way, when the light guide 1 is installed on a construction surface such as a ceiling surface, a holder 20 as shown in FIG. 17 is used. This holder 20 is one in which a stopper 22 is provided at one end of a belt 21 made of synthetic resin, and the belt 21 is provided after the belt 21 is wound around the light guide 1.
When the other end of the belt is passed through the stopper 22 and tightened, the belt 2
The length of 1 can be maintained at the tightened length. This type of holder 20 is sold as a binding band for electric wires under the name of Insulock.
In order to fix to the construction surface such as the ceiling using this holder 20, the fixing tool 23 fixed to the construction surface is tied together with the light guide 1.

Further, as shown in FIG. 18, some of the holders 20 include a fixture 24 fixed to a construction surface such as a ceiling and a belt 25 made of synthetic resin. This fixture 24
Has a U-shaped holding portion 24a that opens downward, and is attached to the belt 25 and both leg portions of the holding portion 24a in a state where both end portions of the belt 25 are in contact with the outer surfaces of both leg portions of the holding portion 24a. By inserting the headless bolt 26a and screwing the cap nuts 26b on both ends of the bolt 26a,
The belt 25 is connected to the fixture 24.
Therefore, by connecting the belt 25 to the fixture 24 while the belt 25 is wound around the light guide 1, the light guide 1 can be attached to the construction surface.

[0007]

In the configuration shown in FIG. 17, the amount of deformation of the light guide 1 changes depending on the amount of tightening of the belt 21, and the belt 21 is attached to a plurality of locations on the long light guide 1. In that case, there is a problem that the light guide 1 is distorted and cannot be mounted straight. In addition, this type of belt 21 has a problem that it does not look good because the end portion is left over.

The configuration shown in FIG. 18 is better than the configuration shown in FIG. 17 in terms of appearance, but the light guide 1 may be distorted due to the tightening amount of the cap nut 26b, and the cap nut 26b. If the belts 25 are attached at many places because of the work of tightening, the construction work will take time. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a light guide holder that has a good appearance and enables construction work in a short time.

DETAILED DESCRIPTION OF THE INVENTION

(Embodiment 1) In this embodiment, as shown in FIG. 1A, a metal fixture 31 fixed to a construction surface such as a ceiling surface, and a fixture that is hung around a light guide 1. The holder 32 is made up of a support 32 whose both ends are joined to 31.
0 is configured. As shown in FIG. 1B, the light source 2 is arranged at one end of the light guide 1, and the end reflector 3 is attached at the other end. The configuration excluding the holder 30 is basically the same as the conventional configuration.

The light source 2 uses a HID lamp or an electrodeless discharge lamp as the lamp 51, and is provided with a reflection plate 52 formed by aluminum drawing. The reflecting plate 52 has an opening surface formed in a circular shape. Also, the lamp 5
A light source unit 53 having a built-in lighting device for lighting 1 is provided, and the lamp 51 and the reflection plate 52 are attached to the light source unit 53.

The fixture 31 includes a raceway 33 extending in a direction orthogonal to the plane of FIG. 1A, and a fixture 34 fixed in place in the longitudinal direction of the raceway 33. The raceway 33 is formed in a U-shaped cross-section that opens downward, and has a shape in which locking pieces 33a (see FIG. 2) project inwardly from the tip ends of both leg pieces. Further, the fixture 34 has a horizontal piece 34a that matches the opening surface of the raceway 33, and the locking pieces 33 are provided from both ends of the horizontal piece 34a.
A pair of positioning pieces 34b are extended obliquely downward along the shape of a, and mounting pieces 34c are extended obliquely upward from the tips of the respective positioning pieces 34b to form a W shape as a whole. In order to fix the fixture 34 to the raceway 33, the pressing plate 4 arranged so as to straddle both the locking pieces 33a.
1 and a wing nut 43 screwed into a screw 42 inserted through the pressing plate 41. In other words, when the pressing plate 41 is arranged so as to straddle both the locking pieces 33a, the lateral piece 34a of the fixture 34 is inserted into the screw 42, and then the wing nut 43 is screwed into the screw 42 and tightened, The positioning piece 34b is fixed in close contact with the locking piece 33a.

By the way, a metal wire is used for the support 32. It is desirable that this type of wire has elasticity and rigidity, and for example, a stainless steel wire having a diameter of 3 mm can be used. The support 32 is formed in a U shape curved along the outer shape of the light guide 1.
Hook portions 32a that are curved in a U shape are formed at both ends of the light guide 2 on the side away from the light guide 1. Hook part 32a
Is a coupling hole 34d formed in the attachment piece 34c of the attachment 34.

The retaining piece 34e has one end fixed to the mounting piece 34c at a portion that does not overlap the coupling hole 34d, and the other end is attached to the mounting piece 34c.
It is closely attached to c. When the hook portion 32a is inserted into the coupling hole 34d, the other end of the retaining piece 34e bends so as to be pushed up by the hook portion 32a, and once separates from the mounting piece 34c.
When the hook portion 32a gets over the retaining piece 34e, it comes into close contact with the mounting piece 34c again to close a part of the coupling hole 34d. In this way, the tip edge of the hook portion 32a is locked to the retaining piece 34e, and the support 32 is coupled to the fixture 34 so as not to fall off.

When installing the light guide 1, the raceway 33 is fixed to a construction surface such as a ceiling surface, and the fixtures 34 are fixed to the raceway 33 at a plurality of positions in the longitudinal direction. Further, one hook portion 32a of the support body 32 is engaged with each attachment 34. When the light guide 1 is fitted into the support 32 in this state, the light guide 1 is attached to the support 3
It is temporarily held by 2. That is, a member having a certain degree of rigidity is used instead of the string-shaped member as in the conventional configuration.
Therefore, the light guide 1 can be temporarily held because it is used as the light guide 2. In this state, the position of the light guide 1 in the longitudinal direction can be adjusted, and workability is improved by performing the alignment in the temporary holding state.

In this way, with the light guide 1 temporarily held by the support 32, the hooks 32a are inserted into the coupling holes 34d of the fixture 34 while flexing each support 32 in the diameter reducing direction. At this time, the support 32 can be coupled to the fixture 34 simply by pushing the hook portion 32a into the coupling hole 34d while bending the support 32 in the diameter reducing direction. Fixing work of the light guide 1 becomes easier as compared with the configuration. Moreover,
Since the size of the support 32 can be made constant by factory management, the light guide 1 can be held without being distorted. Moreover, since the light guide 1 is not distorted, it looks good.

(Second Embodiment) As shown in FIG. 4, the present embodiment is different from the first embodiment in the shape of the coupling hole 34d and the position of the retaining piece 34e in the fixture 34. That is, although the coupling hole 34d is formed in a straight line in the first embodiment, it is formed in an L shape in the present embodiment, and the L-shaped vertical piece inserts the hook portion 32a into the coupling hole 34d. And the L-shaped horizontal piece serves as the hook portion 32a.
It functions as a locking part that keeps the With such a configuration, the retaining piece 34e is arranged so as to cover the introduction portion. Also in this configuration, the upper end edge of the retaining piece 34e in FIG. 4 is fixed to the mounting piece 34c.

In the structure of this embodiment, when the hook portion 32a is inserted into the coupling hole 34d through the introduction portion, the retaining piece 34e is formed.
Is bent once and the hook portion 32a is introduced into the locking portion, the retaining piece 34e returns to its original state. In this state, the retaining piece 34e
Since e covers the introduction portion, the hook portion 32a does not bend the retaining piece 34e even when a tensile force in the extension direction of the support body 32 acts, and thus the hook portion 3a is larger than that of the first embodiment.
The retaining effect of 2a is enhanced. Other configurations and functions are similar to those of the first embodiment.

(Third Embodiment) This embodiment is the same as the first embodiment.
In the above configuration, as shown in FIG. 5, the support 32 is not a wire rod but a band member. According to this configuration, the strength of the support 32 is improved as compared with that of the first embodiment, and the light guide 1 can be supported by a smaller number of the support 32 than the configuration of the first embodiment. If the same number of supports 32 are provided, the configuration of the present embodiment has a higher function of preventing the light guide 1 from falling due to vibration or the like, as compared with the configuration of the first embodiment. Other configurations and functions are similar to those of the first embodiment.

Since the light guide can be held by connecting the support and the second support, there is an advantage that workability is good. Further, since the support is bent along the outer shape of the light guide, the light guide can be held without being deformed, and the first support and the second support engage the coupling hooks with each other. Therefore, the work of connecting the first support and the second support is easy.
