Abstract

PURPOSE:To facilitate mounting/dismounting of lamp from a lamp socket associated with a light-shield type water-proof packing by employing a resilient mounting/dismounting tool having specifically formed inner-diameter section at the tip and the outercircumferential section. CONSTITUTION:An illumination display for road is made of many swan type lamp sockets 18 fixed to a display panel 16, a lamp 12, and a light-shield waterproof packing 13 surrounding said socket 18. While a lamp mounting/dismounting tool 15 molded of rubber where the lamp fitting hole 11 at the tip is tapered to be larger than the outerdiameter of lamp 12 at the tip side while to be smaller at the inner end side and having the outercircumferential diameter larger than the inner diameter at the contacting section 14 between the packing 13 and the lamp 12 is provided. Consequently, when applying said tool 15 over the lamp 12 and deforming the contacting section 14, mounting/dismounting of lamp 12 can be facilitated reliably.

Description

Detailed Description of the Invention (16 Fields of the Invention) The present invention relates to a lamp attachment/detachment device, such as a light-shielding hood-like waterproof device that surrounds a lamp and has an inner surface in contact with the lamp, such as a road electric display device. Relates to mounting a lamp against a lampholder having a backing.

[Technical background of the invention]

As shown in FIG. 5, the conventional lamp attachment/detachment tool of this kind has a structure in which a clamping hole 3 for clamping the tip of the lamp 2 is formed on the front end surface of a detachable member 1 made of rubber or the like. It was getting worse.

[Problems with background technology]

In conventional lamp attaching/detaching tools, a light-shielding hood-like waterproof backing that surrounds the lamp 2 and has an inner surface in contact with the lamp is installed in the socket. Due to the large contact pressure, the lamp 2 cannot be installed in the socket 1~, and when the lamp 2 is removed, the lamp 2 is lowered to the backing while the lamp is being handled, so the lamp 2 comes off from the attachment/detachment part 1 and is easily removed. It has the disadvantage that it cannot be pulled out.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and the lamp is not in direct contact with the light-shielding hood-like waterproof backing that surrounds the lamp. ;? This is what we provide.

(Summary of the Invention) The present invention has been made in view of the above-mentioned drawbacks. The outer circumferential surface of the tip side is formed with a diameter larger than the inner diameter of the contact part with the lamp formed on the inner circumference of the waterproof backing in the shape of a light-shielding hood that surrounds the lamp and contacts the outer circumference of the lamp, and is molded with an elastic material. This lamp is characterized by fitting the lamp into the lamp fitting hole when the lamp is being held or crotched, and the tip of the lamp is interposed between the lamp and the backing to attach and detach the lamp.

(Example of the invention) The development of an embodiment of the present invention will be described with reference to the drawings.

101 is a lamp mounting/removable concrete molded from rubber or the like, and a lamp fitting hole 11 is opened on the tip surface.The tip side of the six holes 11 for the lamp 1 is larger in diameter than the outer diameter of the lamp 12, and the inner end side is the lamp fitting hole 11. The diameter is gradually reduced in a taper shape from the distal end side toward the inner end so that the diameter is smaller than the outer diameter of No. 12. The outer circumferential surface on the front end side of the lamp attachment/detachment member 10 is formed to have a larger diameter than the inner diameter of a contact portion 14 that comes into contact with the lamp 12 of the backing 13, which will be described later.

Further, the rear end of this lamp attachment/detachment member 10 is formed into a grip portion 15 .

Next, as shown in FIGS. 3 and 4, the road electric display device has a large number of swan-shaped lamp sockets 18 installed vertically and horizontally on the socket mounting plate 17 of the display panel 16. A waterproof backing 13 in the form of a light-shielding hood is attached to the backing 1.
A light shielding part 19 whose diameter is enlarged by t is integrally formed on the tip side of 3. A contact portion 14 is formed in an annular shape on the inner circumferential surface of the backing 13 and comes into contact with the outer circumference of the lamp 12 which is fitted into the lamp fitting hole 1-18.

The backing 13 is made of a material that is more flexible than the removable concrete 10.

Next, the operation of this embodiment will be explained. When installing the lamp 12, use the thin I fitting hole 11 of the lamp @ deconcrete 10.
When the lamp 12 is fitted and inserted through the opening at the tip of the backing 13, the tip of the lamp attachment/detachment concrete 10 comes into contact with the contact portion 14 of the backing 13, and the backing 13 is deformed so as to be crushed toward the socket 18. It reaches the base part 20 of the lamp 12 and engages the bottle 21 of the base part 20 fA122
The lamp 12 can be attached to the socket 18 by engaging the lamp attachment/detachment member 10 and rotating the lamp attachment/detachment member 10.
When the concrete 10 is pulled flat, it comes off the lamp 12, and in this state, the contact portion 14 of the backing 13 is attached to the outer peripheral surface of the lamp 12.
contact with each other due to elasticity, and the lamp 12 is securely attached to the lamp socket 18.

Further, when removing the lamp 12 from the socket 18, insert the lamp attachment/detachment part 10 from the opening at the tip of the backing 13, and the lamp 1IB2 Yokyuu 10 advances while inserting the lamp 12 into the v1@hole 11, and the lamp attachment/detachment part 1 ()
The tip of the backing 13 presses the contact part 14, and the rose
The backing 13 is deformed so as to be crushed.
After releasing the contact between the two lamps 12, the lamp attachment/detachment unit 10 fits and holds the lamp 12 in its fitting hole 11, and the lamp 1ll is released.
By rotating the t2 concrete 10, the lamp 12 can be removed from the lamp socket 18.

41 In the above embodiment, the inside diameter of the lamp fitting hole 11 is tapered and decreases in diameter from the tip side to the inner end side, but as shown in FIG. 12
It is also possible to provide a fitting hole 11 having a diameter larger than the outer diameter of the lamp 12 and having an inner tl on the inner end side smaller than the outer diameter of the lamp 12.

(Effects of the Invention) According to the present invention, a lamp fitting hole is formed in which the inner diameter on the tip side is larger than the inner diameter of the lamp and the inner diameter on the inner end side is smaller than the outer diameter of the lamp, and the outer periphery on the tip side is formed. Since the surface has a larger diameter than the contact part formed on the inner periphery of the backing that surrounds the lamp, it is possible to release the contact between the lamp and the backing (in '2187), so that the lamp can be easily and reliably attached and detached. be..
