Description

[Detailed description of the invention] (a) Technical field This invention is a lighting equipment hanging unit (hereinafter referred to as
It's called a unit. ) regarding.

(b) Prior art and its drawbacks As illustrated in Fig. 4, this type of unit A
The upper and lower parts of a pair of conductive wire rods 1 and 2 are fixed to insulating supports 3 and 4 with a space between them, and hook-shaped hook-like hooks 1a and 1 are attached to both ends of each wire rod 1 and 2.
b, 2a, and 2b were formed.

When constructing a decorative lighting equipment using such a unit A, for example, as shown in FIG.
Hang it by hooking the upper hooks 1a and 2a,
Hook the upper hooks 1a, 2a of wire rods 1, 2 of another unit A onto the hooks 1b, 2b on the lower side to hang it, and then hang the required number of units A one after another in the same way. . Then, the wire rods 7 and 8 of the lighting fixture B, such as a lamp, are hooked to predetermined locations on the pair of wire rods 1 and 2 of each unit A.

In such lighting equipment, the latching fittings 5, 6, the wires 1, 2 of unit A, and the wires 7, 8 of lighting fixture B are used.
Since these are electrically connected, there is no need to separately connect or support lighting fixture B and conduct electrical wiring when installing it, and if you perform the work for connecting or supporting lighting fixture B, you can also perform the electrical wiring work at the same time. There are advantages.

However, the lengths of the pair of wire rods 1 and 2 in unit A often vary;
As shown in the figure, the length L ₂ of the other wire 2 may be slightly shorter than the length L ₁ of one wire 1 . In such a case, when a plurality of units A are suspended as shown in FIG. 5, the wire rods 1 and 2 of each unit A are likely to have poor contact with each other. However, in the conventional unit A, the wire rods 1 and 2 were fixed to the supports 3 and 4, so there was no function to absorb the difference in their length, and the above-mentioned contact failure frequently occurred. .

(c) Purpose of the invention This invention was made to improve the shortcomings of conventional units, and the purpose was to provide a unit with the function of absorbing variations in the length of a pair of wires. There is.

(d) Structure and effect of the device In order to achieve the above object, the main points of this device are to provide an elastically expandable bending section in the middle of the wire, and to hold the wire in a slidable manner on a support. It is said that

According to this configuration, even if there is variation in length between a pair of wires, when another unit is suspended from one unit, the wire will stretch at the bend due to its weight, and the shorter wire will have the same length as the longer wire. Therefore, the difference in length due to the above-mentioned variations can be effectively absorbed. Therefore, there is no room for the above-mentioned contact failure to occur.

(e) Embodiment In the unit A illustrated in FIG. 1, a pair of conductive wires 1 and 2 are held at two upper and lower positions by insulating supports 3 and 4 with an interval between them. These supports 3, 4 are a pair of split members (for example, synthetic resin molded products) 31, 4 as clearly shown in the figure.
1 are connected to each other. The split member 41 of the lower support 4 has an L-shaped groove 42 for accommodating the wire, as shown in FIG. The horizontal portion 42 of this L groove 42
The width of the groove a is set larger than the outer diameter of the wire, for example, wire 2, accommodated in this L-shaped groove 42, and the wire 2 accommodated in this L-shaped groove 42 can slide up and down within a certain range. It is structured as follows.
The other wire rod 1 is similarly held by the support body 4 in a slidable manner. Further, the pair of wire rods 1 and 2 are also slidably held on the upper support body 3.
Note that the upper support body 3 is provided with a stopper (not shown) to prevent the wire rods 1 and 2 from slipping down.

Next, as is clear from FIG. 1, the pair of wire rods 1 and 2 have their middle portions bent in a U-shape, and these bent portions 11 and 21 are arranged symmetrically. Further, the wire rods 1 and 2 are formed with recesses 12 and 22 for hooking a lamp (see FIG. 5).

According to the unit A, the bent portions 11 and 21 of the wire rods 1 and 2 can be expanded and contracted against the elasticity of the wire rods 1 and 2. This is allowed by sliding displacement of the wire rods 1 and 2 within. Therefore, even if the lengths of the pair of wire rods 1 and 2 vary, the wire rods 1 and 2
When another unit is hooked onto the hooks 1b and 2b of the unit and hung, the weight of the unit causes the shorter wire to stretch to the same length as the longer wire. Therefore, in units connected in a hanging manner, poor contact between the wire rods does not occur.

FIG. 3 shows another embodiment. In this embodiment, the bent portions 11 and 21 of the wire rods 1 and 2 are formed in an arc shape. In addition, the lower support body 4 has protruding bent portions 13 and 23 formed on the wire rods 1 and 2.
Engagement portions 43a and 43b are formed for each.
In such a unit A, even if wire rod 2 is shorter than wire rod 1, if another unit is hung from the hanging parts 1b and 2b of wire rods 1 and 2, the wire rod 2 will be shorter than wire rod 1, as shown by the imaginary lines in the same figure. The bent part 21 of wire rod 2 is connected to wire rod 1.
The hook 2b is set at the same height as the hook 1b. Therefore, contact failure does not occur.

Note that the bent portion provided on the wire may be in the U-shape shown in the figure, an arc, or any other shape, but if it is made in an arc, it will resist the elasticity of the wire. The bending part exhibits good elasticity.
