Description

[Detailed description of the invention] (a) Technical field This invention relates to a hanging lighting fixture unit used for decoration, etc.

(b) Prior art and its drawbacks This type of decorative hanging lighting unit (hereinafter referred to as
It's called a unit. ) are often used by hanging multiple items connected together from the ceiling, etc.

Conventionally, when installing such units, the work of connecting the units and the work of running electrical wiring between the bulbs of each unit had to be done separately, and these tasks required soldering and screws. Since the work of fixing the lights was complicated, there was a drawback that it required a great deal of effort and time, especially when installing a decorative lighting fixture by connecting a large number of units.

For the same reason, changing the combination of units and cleaning the remaining lighting equipment is complicated and takes a long time.

(c) Purpose of the invention This invention was made in order to improve the drawbacks of the conventional equipment. The purpose is to provide a unit that can be used in a one-touch manner.

(d) Structure and effects of the invention In order to achieve the above object, the unit of this invention includes a hanging member made of a pair of left and right conductors with hanging parts at both upper and lower ends, and a pair of hanging members that are not connected to each other. The fixing member includes a pair of insulating split members that are brought into contact and held together, and a socket that holds a light bulb, and the split member is provided with a recess for holding a flange provided on the socket. The socket is also characterized in that the socket is provided with an electrical contact that is pressed into contact with the locking member by one of a pair of split members that are coupled to each other.

With the above configuration, each unit can be connected to each other by simply hooking the latching parts of the respective latching members, and through this connection operation, the latching members of each unit are electrically connected to each other. Therefore, connection work and electrical wiring can be done simultaneously in a one-touch manner. Therefore, the installation of decorative lighting equipment,
Changes in unit combinations, cleaning work, etc. can be easily and quickly performed without complicated work such as soldering or screwing. In particular, according to the unit of this invention, the locking member is held between a pair of split members, and the electrical contact provided on the socket is pressed against the locking member by one of the split members. Therefore, the electrical contact can be reliably kept in electrical contact with the latching member for a long period of time without using troublesome means such as soldering. In addition, since the above socket can be attached to the unit by simply fitting the flange into the recess of the split member and holding it, replacing a defective socket and electrical wiring to the socket can be done quickly and easily in one operation. You will be able to do it for sure.

(e) Embodiments Hereinafter, embodiments of this invention will be explained with reference to the drawings.

FIG. 1 is an exploded perspective view of a unit that is an embodiment of this invention. This unit includes a pair of left and right hanging members 1, 1, an upper fixing member 2, a lower fixing member 3, and a socket 4, into which a light bulb 5 can be attached and detached.

The hanging member 1 in the figure is composed of a plate-shaped conductor,
It has hook parts 1a and 1b at both upper and lower ends, respectively, and the inner end of the middle part is recessed in an arc shape,
Moreover, the outer end of the intermediate portion is protruded in a chevron shape. The upper fixing member 2 is made up of a pair of insulating semi-cylindrical split members 21 and 22, and these split members 21 and 22 have the above-mentioned latching members 1 and 1 on both ends of their mating surfaces. The stepped portions 21a, 21a, which are fitted into the
22a, 22a are provided, respectively. One split member 21 has stepped portions 21a, 21.
a is provided with protrusions 21b, 21b, and the stepped portion 21
This protrusion 21b is fitted into and engaged with the engagement hole 1c of the locking member 1 that is fitted into the locking member 1a. Further, this split member 21 is provided with a recess 21c, and a flange 4 of a socket 4, which will be described later, is inserted into this recess 1c.
1 is now fitted. The other split member 2
2 has substantially the same structure as one of the above-mentioned split members 21, except that it does not have the above-mentioned protrusion 21b. Then, by inserting the bolt 21d installed in one split member 21 into the hole 22e of the other split member 22 and tightening a nut (not shown), these split members 21 and 22 are joined together, and A pair of hanging members 1, 1 are firmly held between these split members 21, 22 in a non-contact state. The lower fixing member 3 also consists of a pair of insulating semi-cylindrical split members 31 and 32. These split members 31, 3
2 has the same structure as the split members 21 and 22 described above except that it does not have a portion corresponding to the recess 21c described above, and is joined together by inserting a bolt 31d into a hole 32e and tightening a nut (not shown). At the same time, the pair of hanging members 1, 1 are firmly held between these split members 31, 32 in a non-contact state. In this way, by sandwiching the pair of hooking members 1, 1 at two locations between the upper fixing member 2 and the lower fixing member 3, a unit with excellent strength can be obtained.
Next, the socket 4 has a flange 41 and a pair of electrical contacts 42, 42 made of metal pieces protruding from both left and right sides of the flange 41. It is designed to be electrically connected to the cap 51 of No. 5. The socket 4 is held by fitting the flange 41 into the recesses 21c when the split members 21 and 22 are joined together. When the socket 4 is held by the pair of split members 21 and 22 in this manner, the pair of electrical contacts 42 and 42 are connected to the pair of latching members 1 and 22 by one of the split members, in the illustrated example, the split member 22. 1, and these are electrically connected.

FIG. 2 shows a case where a plurality of units A are suspended to form a decorative lighting fixture. As is clear from the figure, between the two units A, the lower hooking part 1 of the upper unit A
Units A and A can be connected by simply hooking the upper hooks 1a and 1a of the lower unit A onto b and 1b.
The hooking members 1, 1 are connected to each other, and the hooking members 1, 1 are electrically connected to each other. Also, each unit A,
The sockets 4, 4 of A are electrically connected to each other via the latching members 1, 1. Therefore, if each socket 4 holds a light bulb 5 as shown in the figure, the lighting fixture will have a decorative effect. In this case, as shown in FIG. 1, if the light bulb 5 is housed in a sphere 6 whose surface is a diamond-cut surface and whose upper half has a reflective surface 61 made of a metal vapor-deposited film, the luminance will increase. A light source with high intensity and concentrated illumination light can be obtained, and a high decorative effect can be achieved.

In addition, in FIG. 2, the unit A at the top is attached by hooking the hooking parts 1a, 1a of the hooking members 1, 1 to the engagement terminals 7a, 7a of the fixture 7 fixed to the ceiling. It is hanging.
