[0006]

By the way, in this luminaire, various parts arranged in the luminaire main body 1 are connected by lead wires as shown in FIG. Especially,
The pull switch PS is configured such that a pair of rotary contacts TP contact the contact portions a to h formed in a sawtooth shape, and conductive contacts are arranged only on the contact portions a, c, e, and f. Electrical connection is possible. The rotary contact TP of the pull switch PS has one of the commercial power sources AC, the contact portion a has the power terminal of the first ballast BL1 and the contact portion c.
Has one terminal of the bead ball socket SB3 and the contact portions e and f.
Is connected to one terminal of the second ballast BL2.

In this state, by pulling the pull cord 5 hanging down through the V-shaped spring 4 downward, the rotary contact TP of the pull switch PS is brought into contact with the contact portions a to h in a predetermined direction while appropriately contacting the contact portions a to h. The ring-shaped fluorescent lamps 13a and 13b and the bead ball (SB3) are turned on or off as appropriate. For example, when the rotating contact TP contacts the contact portions a and e, the first and second annular fluorescent lamps 13a and 13
b lights up at the same time. Next, when the rotary contact TP articulates and rotates by one pitch, the rotary contact TP contacts the contact portions b and f, the first ring-shaped fluorescent lamp 13a is turned off, and only the second ring-shaped fluorescent lamp 13b is turned off. The lighting is maintained. Next, when the rotation contact TP contacts the contact portions c and g when the articulation and rotation are performed by one pitch, the second annular fluorescent lamp 13b
Is turned off and the bean ball (SB3) is turned on. Further, when the rotation contactor TP contacts and contacts the contact portions d and h by one pitch, since the conductive contact is not arranged, the bead ball (SB3) is also turned off and all the lights are turned off. Can be switched to Therefore, the turning on or off of the ring-shaped fluorescent lamps 13a and 13b and the bead ball can be freely switched by the pulling operation of the pulling string 5.

However, this direct mounting type lighting fixture has the following problems when the V-shaped spring 4 is fixed to a substantially vertical wall surface so as to be horizontal as shown in FIG. 24, for example. Occurs. That is, as shown in FIG. 25, when the pull string 5 is pulled in the direction indicated by the arrow in the drawing, the pull string PSa is also pulled, so that the pull switch PS performs a switching operation. At this time, the V-shaped spring 4 is connected to its ring. When the downward pulling force acts on the portion 4b, the locking leg 4a located on the upper side tends to come off from the first locking portion 2 on the upper side as shown by a dotted line in the drawing, and the spring located on the lower side. The portion of the lower locking leg 4a tends to come off from the lower first locking portion 2 due to the rotational force of which the second locking portion 3 is a fulcrum. In particular, when the pull force is large, the locking leg 4a of the V-shaped spring 4 is detached from the first locking portion 2, and
When the pulling force on the drawstring 5 is released in the detached state, the locking leg 4a may be disengaged from the second locking portion 3.
May not be inserted into the locking portion 2 and may come off. If the pulling string operation is performed again with the pulling string 5 in such a state, the V-spring is completely disengaged from the locking portions 2 and 3, and a problem arises that the pull switch PS can no longer be smoothly switched. .

Therefore, an object of the present invention is to provide a switch having a pull switch function and a smooth switch operability irrespective of the state in which the instrument body is fixed to the mounting surface by a relatively simple structure. And to provide a direct-mounted lighting fixture.

The lighting or extinguishing of the first and second annular fluorescent lamps 13a and 13b and the bean ball in this lighting apparatus is as follows.
This is performed as shown in FIG. 9 and FIG. First, V
When the pull cord 5 suspended through the spring 4 is pulled downward once, the operating lever 34 of the pull switch unit 24 rotates within a certain angle range, and the rotary contact 36 also moves by one pitch.・ The contact pieces 36a and 36b rotate to be
As shown by the solid line in (b), the contact portions a and e are brought into contact, whereby the first and second annular fluorescent lamps 13a and 13b are simultaneously turned on. Next, when the rotary contact 36 is articulated and rotated by one pitch, the rotary contact 36 contacts the contact portions b and f as shown by the dotted line in FIG. 13B, and the first ring-shaped fluorescent lamp 13a is turned off. Then, only the second annular fluorescent lamp 13b is kept turned on. Next, when the joint is rotated and rotated by one pitch, the rotating contact 36 comes into contact with the contact portions c and g as shown by a dashed line in FIG. 13B, and the second annular fluorescent lamp 13b
Is turned off and the bean ball (27) is turned on. Further, when the articulation and rotation are performed by one pitch, the rotating contact 36 becomes the one shown in FIG.
Although it contacts the contact points d and h as indicated by the two-dot chain line,
Since no conductive contact is provided, the bead ball (27) is also turned off and all lights are switched off. Therefore, the turning on or off of the ring-shaped fluorescent lamps 13a and 13b and the bead ball can be freely switched by the pulling operation of the pulling string 5.

By the way, the instrument main body 1A is fixed to a substantially vertical wall surface, and the drawstring 5 is connected to the ring portion 4b of the V-shaped spring 4.
When the pull string 5 is pulled in the direction indicated by the dotted line in the case where the pull string is hung down as shown by the dotted line in FIG. 4 via the, the pull switch unit 24 performs a predetermined switching operation based on the pull string operation. At this time, a force is exerted on the locking leg 4a located above the V-shaped spring 4 to disengage it from the locking portion 2 as the V-shaped spring 4 is deformed downward. Stop 4
As a result, the spring portion adjacent to a is brought into contact with the stopper portion 3A, so that the locking leg portion 4a is prevented from coming off from the locking portion 2. This is particularly because the length L1 of the locking leg 4a is
This is because the distance L2 is set to be larger than the distance L2 between the stopper 3A. Therefore, the V-shaped spring 4 cannot be removed from the locking portion 2 unless the locking leg portion 4a is guided to the slit 3Ab of the stopper portion 3A.

The pull switch 2 of the wiring block 20
In 4, the operation lever 34 and the rotary contact 36 which is pivoted and rotated in accordance with the rotation of the operation lever 34 rotate in a plane substantially parallel to the base body 21 and the cover body 22. When the wiring block 20 is fixed to the appliance main body 1A so that the base body 21 and the cover body 22 are substantially parallel to each other, when a pulling force is applied to the pull cord 5 led out along the appliance main body 1A, The operation lever 34 rotates extremely smoothly with a relatively small force. Accordingly, it is possible to freely switch on and off the ring-shaped fluorescent lamps 13a and 13b and the bead ball (27) by the pulling string operation.

In particular, the wiring block 20 is connected to the appliance body 1A.
The first protruding portions 21a and 22a are formed in the holes 1 of the taper portion 1b.
Since it is arranged to be inserted into the cc, the drawstring 5 derived from the pull switch portion 24 is separated and protected without contacting the hole 1cc of the metal instrument body 1A. Therefore, no matter how the drawstring 5 is operated, the drawstring 5 is not rubbed and cut at the edge of the hole 1 cc. It is not necessary to partially use a drawstring made of a metal wire unlike a pull switch, and the cost can be effectively reduced because all parts can be formed of a resin material such as nylon.

In addition, when the wiring block 20 is applied to an insect-proof lighting device, the wiring block 20 becomes
In addition, the taper portion 1b is formed by the first protrusions 21a and 22a.
If the hole 1cc is arranged so as to be closed, the hole 1cc
No gap is formed between the first protrusions 21a and 22a. Therefore, it is not necessary to arrange a packing such as a sponge for insect control in this portion, and it is possible to reduce not only the assembling workability but also the cost.

Further, the wiring block 20 is provided on the tool body 1A, and the first projecting portions 21a and 22a are provided on the taper portion 1b.
And is fixed by inserting and screwing one screw 38 into the mounting hole 28 of the second protruding portions 21b and 22b after being arranged to be inserted into the hole 1cc of the wiring block 20. Can be easily incorporated into the instrument main body 1A, and the assembling workability can be improved.

In particular, since the mounting hole 28 is formed substantially on the opposite side of the lead-out hole 31a of the pull switch portion 24, when a pull force is applied to the drawstring 5, most of the pulling force is applied to the mounting hole 28. 3 screw inserted and screwed into the instrument body 1A
8 will work. Therefore, even if there is only one screwing portion, an extremely stable mounting state can be ensured.

In addition, since the bulging portion 30 of the base body 21 is inserted and engaged with the concave portion or hole formed in the instrument body 1A, the wiring block is combined with the fixing effect of the screw 38. It is possible to further enhance the stability of the mounting state of the device 20 to the device main body 1A.

FIG. 15 shows a second embodiment of the wiring block according to the present invention.
This is the same as the embodiment shown in FIG. The difference is that the first protrusions 21a and 22a are omitted, and a drawstring 5A made of a metal wire is derived from the operation lever. In addition, the instrument body 1A
At the time of assembling, the drawstring 5A made of nylon or the like is connected to the leading end of the drawstring 5A.

According to this embodiment, the present invention can be easily applied to an existing lighting device having a small hole formed in a taper portion of the device body without any modification or change to the device body. .

FIG. 16 shows a third embodiment of the luminaire according to the present invention, which is basically the same as the embodiment shown in FIGS. The difference is that a pair of stoppers
The portions 3B and 3B are cut and raised substantially in an L shape, and a slit 3Ba is formed in the opposing portion. still,
The relationship between the length of the locking leg 4a of the V-shaped spring 4 and the distance between the locking portion 2 and the stopper 3B is the same as in the embodiment shown in FIG.

According to this embodiment, similarly to the embodiment shown in FIGS. 4 and 5, the support state of the V-shaped spring 4 on the instrument body 1A is stably maintained by the locking portion 2 and the stopper portion 3B. be able to. That is, the instrument body 1A is
After the spring 4 is fixed so as to be in a horizontal state, even if a force is applied to the locking leg 4a from the locking portion 2 by pulling string operation, the stoppers 3B prevent the removal. Is done. Therefore, the pull switch operation can be easily performed in any mounting state. In particular, even if the stopper portion 3B is composed of only one, as long as the ring portion 4b of the V-shaped spring 4 is positioned protruding from the peripheral edge of the instrument body 1A.
Similar effects can be obtained.

It should be noted that the present invention is not limited to the above-described embodiment, but includes, for example, a direct-mount type lighting device for a ring-type fluorescent lamp, a direct-mount type fluorescent lamp, a compact fluorescent lamp, and the like. It can be applied to lighting equipment. In addition, the fixture body can be attached to the ceiling by using a connecting means such as a hook seal, or directly by screws or the like. May be configured in a polygonal shape. or,
A single pull switch can be used as the component having the pull switch function. Further, the V-shaped spring includes U-shaped and U-shaped in addition to the V-shaped spring.

[0031]

As described above, according to the present invention, the locking leg of the V-shaped spring is inserted and locked in the locking portion, and the spring portion adjacent to the locking leg is formed with the locking portion. Since it is arranged so as to be restricted in position between the stopper and the stopper, if the device main body is fixed to a substantially vertical wall surface, the V-shaped spring includes a surface including each spring portion by a pulling string operation. Even if a force acting in the direction acts to detach the locking leg from the locking portion 2, the spring portion adjacent to the locking leg abuts against the stopper portion. The detachment of the leg from the locking portion can be reliably prevented. Therefore, the V-shaped spring is not detached from the instrument main body even if the instrument main body is attached to any mounting surface and the pulling operation is performed via the V-shaped spring. The switching operation can be performed smoothly and reliably.
