JPS5829528Y2 - Yoke mounting device for fluorescent light fixtures - Google Patents

Description

[Detailed explanation of the idea] This invention relates to a yoke mounting device for a fluorescent light fixture.

As is well known, this type of yoke is used for fixing reflectors and positioning fluorescent lamps.

That is, at least two yokes are mounted across the width of the instrument body at appropriate intervals along the length of the instrument body.

The attachment position of the appliance main body to the ceiling is then determined by screwing a reflector to this yoke or by fixing both ends of the yoke to the ceiling edge.

By the way, the yoke is attached to the instrument body by forming a pair of key portions facing each other on the yoke and inserting these from the outside into a hole provided in the side wall of the instrument body.

Specifically, by compressing the side wall of the instrument body inward against its elasticity, inserting it between the opposing key parts, and leaving the hole facing the key part, the side wall O can be un-constricted to reduce the elasticity of the side wall. When it returns to its original position, the key slips into the hole.

This allows the yoke to be attached to the instrument body.

However, with this type of attachment means, if the side wall is carelessly pulled up and lifted, the side wall will curl inward, and the key will come out of the hole, and the yoke will be removed from the lifted instrument body. There are times when something falls down.

The purpose of this invention is to prevent the yoke, once attached, from unnecessarily separating from the instrument body.

An embodiment of this invention will be described with reference to the drawings.

Reference numeral 1 designates an instrument main body having a U-shaped cross section, 2 a side wall, and 3 a yoke.

As shown in FIG. 1, the appliance main body 1 is installed on a ceiling or the like with its open side facing downward.

A hole 4 is formed in the side wall 2 into which a key portion to be described later can be inserted.

The yoke 3 has key parts 5 facing each other with an interval slightly narrower than the width of the instrument body 1.

The key portion 5 is formed into an L-shape along with an upright portion 6 and a bent portion 7 formed by bending its tip.

A space 8 is formed by the standing portion 6 and the bent portion 7,
Further, an inclined portion 9 is formed on the inner surface of the proximal end of the upright portion 6.

An engaging portion 10 facing downward is formed on the inner surface of the tip of the bent portion 7.

11 is a leg portion. To attach the yoke 3 to the instrument body 1, the bent wall 2 is shrunk inward and then inserted between the opposing key parts 5.

Then, after the hole 4 is faced to the tip of the bent portion 7, the side wall 20 is released, and the restoring elasticity of the side wall 2 returns it to its original state. inserted.

This attachment operation has already been explained.

However, if the inclined part 9 is provided according to this idea, after the bent part 7 is inserted into the hole 4 of the side wall 2, the two lower edges of the side wall 2 will climb onto the inclined part 9, so that the instrument body The whole thing lifts against the yoke.

Or, to put it the other way around, the entire yoke 3 is pushed down with respect to the instrument main body 1.

As a result, the lower edge 4A of the hole 4 approaches or comes into contact with the inner surface of the bent portion 7 (see FIG. 3).

). If you try to lift the instrument body 1 with the yoke 3 attached and try to hit the side wall 2, the side wall 2 will try to slide inward, but the lower edge 4A of the hole 4 will hit the engaging part 10, so it will not engage. The lower edge 2 of the side wall 2 beyond the joint 1°
A person cannot turn inward.

This prevents the yoke 3 from coming out of the key part 5, thereby preventing the yoke 3 from detaching from the instrument body 1.

If the inclined part 9 were to be provided, the side wall 2 would not be lifted up relative to the yoke 3, and the lower edge 4A of the hole 4 would not come into contact with the engaging part 10.
It is clear that when the side wall 2 is pulled up in an attempt to lift the key 5, the key 5 will easily come out from the hole 4 if the side wall 2 is bent inward.

As detailed above, according to this invention, the yoke attached to the instrument body has the effect of reliably preventing the yoke from detaching from the instrument body even if the side wall of the instrument body is subsequently lifted in such a way as to compress it. play.
