Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

As shown in FIGS. 1 and 2, there is a ceiling-embedded device that uses a tight spring 4 to attach a panel 3 that closes the opening 2 of the device body 1 to light. That is, as shown in FIGS. 3 to 5, a slit 6 is formed in the vertical piece 5a of the panel frame 5, a ring-shaped spring support 7 having a substantially V-shaped portion is formed of a spring metal plate, and the joint portion 7a is formed. They are kept stacked one on top of the other, and are passed through the slit 6 from the joint 7a as shown in FIG. 5 to allow them to loosely attach, and then are allowed to fall inward for packaging. Also, the joint part 7 of the spring support 7
a through the winding part 4a of the tight spring 4, and position it on the top part 7b of the spring support, and both spring legs 4 of the tight spring 4.
The tip of b is curved to form a locking portion 4c. On the other hand, there is a spring leg 4b inside the instrument body 1 as shown in FIG.
A spring receiver 9 is provided with a slit 9a of a predetermined length into which the spring receiver 9 is fitted. 10 is the ceiling. Panel 3
To install the panel 3, place the panel 3 on the panel frame 5, tighten both spring legs 4b of the spring 4 by hand as shown in Figure 3, and pass the panel frame 5 through the slit 9a of the spring receiver 9 of the device body 1. When pushed into the main body 1, the spring legs 4b lock the panel frame 5 in a drawn state to the instrument main body 1 due to the expanding action of the spring. When replacing the lamp, pull down the panel frame 5 to release the spring legs 4b.
is narrowed along the slit 9a, and the locking portion 4c locks on the edge of the slit 9a. When removing, remove the instrument body 1 and panel frame 5 formed by pulling down.
If the spring leg 4b is tightly gripped through the gap between the spring leg 4b and the spring leg 4b, it will be removed from the slit 9a.

However, when attaching the panel 3 to the main body 1 of this lighting fixture, if you accidentally let go of the tight spring 4, the spring pressure is strong, and the spring force of the spring leg 4b causes the tight spring 4 to move as follows. There was a risk that the panel 3 would be damaged or damaged. That is, (1) due to the reaction when it is released from the hand, the tight spring 4 rotates around the spring support 7, and one spring leg 4b
(2) Due to the reaction when it is released from the hand, the tightening spring 4 moves to the outer vertical part of the spring support 7 and at the same time rotates and hits the panel 3 with the tip of one spring leg 4b. (3) Due to the reaction, the kick spring 4 moves vertically to the panel side (inside) and hits the panel 3 with the tip of the spring leg 4b.

On the other hand, there have been conventional lighting fixtures in which a long hole is formed in the panel frame and the middle part of the spring leg of the stiff spring is inserted into the long hole (for example,
issue). That is, in this lighting fixture, the tight spring is regulated by the elongated hole, so damage to the panel can be prevented.

However, since the middle part of the spring leg of the tight spring is passed through a long hole, the wide open spring leg can be pinched to lock the tight spring to the spring holder when attaching the panel frame to the device body. Since it is only at the tip of the spring leg, it is troublesome to narrow the spring legs, and the panel frame is not easy to attach.

Therefore, an object of this invention is to provide a lighting fixture that can prevent damage to the panel due to the tight spring and also allows the winding side of the spring leg to be easily pinched.

A first embodiment of this invention is shown in FIGS. 6 to 8. That is, in the panel mounting structure of this lighting equipment, a central tongue piece 12 is formed by punching a rectangular sheet metal to form a substantially U-shaped slit 11 as shown in FIG. A recess 13 is formed on the side edge and bent into a substantially U-shape along fold lines 14 and 14', thereby forming a spring support 15 that also serves as a regulating member. This spring support 15 passes through the winding part 4a of the tight spring 4 from the lower end of the central tongue piece 12 located on the vertical piece 15a, and passes through the upper horizontal piece 1.
5b so that the base of the spring leg 4b is supported by the edge of the horizontal slit 11a. This spring support 15
When the vertical piece 15a is attached and fixed to the vertical piece 5a of the panel frame 5 with the screw 16 on the panel 3 of the panel frame 5, the upper horizontal piece 15
b is in a state of protruding from the panel frame 5.

When attaching the panel 3 to the instrument body 1, the spring legs 4b are narrowed and the slits 9 of the instrument body 1 are closed.
Let it pass through a.

With this structure, this lighting fixture has the following effects. That is, (1) since the spring support 15 is fixed to the panel frame 5, its vertical piece 15a serves as a guide for the main body opening when it is attached to the instrument body 1, making it easier to attach. Since the conventional spring supports 7 are loosely attached to the panel frame 5, it is necessary to support the spring supports 7 so that they do not fall during installation. It is difficult to do so, and it may get stuck on the opening edge of the instrument body 1 and become a hindrance to installation.

(2) Since the center tongue piece 12 of the tight spring 4 is fixed, it becomes more difficult to come off.

(3) Attach the slit edge of the horizontal slit 11a to the spring leg 4
Since the spring leg 4b is a restricting portion for over-opening and rotation, even if the spring leg 4b is accidentally released during installation, the edge of the horizontal slit 11a will restrict the spring leg 4b from flipping. In addition, due to the reaction at that time, the spring 4 becomes tight.
Even if the winding part 4a tries to move inward, it is restricted by the edge of the horizontal slit 11a, and even if it can move outward, the vertical piece 15a prevents the spring leg 4b from rotating. This prevents damage and breakage of the panel 3.

(4) The lower horizontal piece 15c of the spring support 15 is attached to the panel 3.
Since it also serves as a presser, there is no need for a separate panel presser.

(5) When packing, the base of the spring leg 4b is held in the recess 13 as shown in Fig. 8, and the tip of the spring leg 4b is locked inside the rising part 5' of the panel frame 5 as a locking part. This makes packaging easier.

A second embodiment of this invention is shown in FIGS. 9 and 10.
As shown in the figure. That is, in the panel mounting structure of this lighting device, the spring support 7' is the same as that shown in FIG. The width of the vertical portion of the slit 18 corresponds to the width of the spring support 7', and a pair of claws 19 are provided at the upper edge of the slit 18 of the vertical piece 17a. Place the winding part 4a of the tight spring 4 on the top part 7b of the spring support 7', and insert it into the slit 1 of the regulating member 17 as shown in FIG.
8 is positioned on the spring support 7' and the regulating member 17 is fixed to the panel frame 5 with screws 16, the winding part 4a of the tight spring 4 is regulated by the claw 19 and the upper edge of the slit 18, so that it is vertically There is no movement to section 7c.

As a result, the rotation of the spring support 7' is regulated via the winding portion 4a of the tight spring 4, so that the panel 3 is not damaged or damaged due to the rebound of the tight spring 4, and the regulating member 17 can be removed from the panel frame 5 during packaging. The regulating member 17 also serves as a panel presser, and the winding part 4a of the tightening spring 4
Since the spring support 7' is fixed through the device, the regulating member 17 serves as a guide when it is attached to the instrument body 1, and the spring support 7' does not get in the way unlike the conventional case.

The third embodiment of this invention is shown in FIGS. 11 and 1.
Shown in Figure 2. That is, the panel mounting structure of this lighting fixture is the same as that shown in FIG. 5 for the spring support 7'.
The regulating member 20 is formed of a U-shaped metal fitting, and a continuous slit 21 is formed in a vertical piece 20a and a horizontal piece 20b, and a claw 22 that projects into the slit 21 is formed in the vertical piece 20a. This pawl 22 is laterally fitted into the spring support 7' and fixed to the vertical piece 5a of the panel frame 5 with a screw 16, so that it also serves as a press for the panel 3.

As a result, the spring support 7' is supported by the claw 22, and the impact on the panel 3 caused by the spring leg 4b when the winding portion 4a of the tight spring 4 is flipped off is prevented. In addition, this embodiment has the same effects as the second embodiment.

The fourth embodiment of this invention is shown in FIGS. 13 and 1.
Shown in Figure 4. That is, in the panel mounting structure of this lighting device, in place of the claw 22 in the third embodiment, a recess 23 is formed at the edge of the horizontal portion of the slit 21 of the regulating member 20', and a tight spring 4 is provided in the recess 23.
The winding part 4a is positioned to restrict the axial movement of the winding part, and the spring support 7' is fixed to the regulating member 20' through this winding part 4a. Its operation and effect are similar to those of the second embodiment.

The fifth embodiment of this invention is shown in Fig. 15 and 1.
It is shown in Figure 6. That is, in the panel mounting structure of this lighting fixture, in the second embodiment, the regulating member 17'
is made of sheet metal and serves as a collar wrapped around the vertical portion of the spring support 7', and its upper opening edge restricts the movement and rotation of the spring leg 4b. Further, in this case, since the spring support 7' remains loosely attached to the panel frame 5, it can be folded inward as shown by the arrow when packing.

As described above, the lighting equipment of this invention includes a main body provided with a spring receiver inside, a panel frame supporting a panel that transparently closes an opening of the main body, and a panel frame provided on the panel frame that supports a spring support protruding inside the instrument body; a tight spring that is inserted through the winding part to lock the spring leg to the spring receiver; and a base of the spring leg of the tight spring in the panel frame. Since the regulating member is provided on the open leg side and regulates the rotation of the winding portion, the regulating member can prevent the tight spring from rotating, and therefore, when the tightening spring is released, a flipping action, etc. This can prevent the panel from being damaged. In addition, since the spring support is provided to protrude from the panel frame to the inside of the device body, when pinching the spring leg to lock it to the spring receiver,
Since the winding side of the spring leg can be pinched, the pinching operation becomes easy, and the panel frame can be easily attached to the instrument body.
