Description

  The present invention relates to a marker lamp that is turned on at night to indicate the width of the truck and the presence of the truck from the lateral direction.

  In particular, in the case of a large truck, in order to increase the lateral width and improve the visibility from the lateral direction, as shown in FIG. 7, 4 to 8 marker lamps 101 are attached to both sides of the vehicle body 100, respectively. Yes.

As shown in FIG. 8, the marker lamp 101 has a metal bottom plate 103 fixed to a metal mounting plate 102 mounted downward on both sides of the vehicle body 100 with bolts 104 and nuts 105. The LED 106 and the reflector 107 are configured to be covered with a transparent resin cover lens 108. The cover lens 108 is configured to press and fix the outer periphery joined to the bottom plate 103 via a packing 109 with a ring 110 having a semicircular cross section.
Further, the LED 106 inside is detachably attached to the socket receiver 113 on the bottom plate 103 side through the socket 112, and the power lead wire 114 of the LED 106 uses a stranded wire.

The conventional marker lamp having the above configuration has the following drawbacks.
1. When the truck runs during rainfall, rainwater intrudes into the inside due to wind pressure at the joint between the bottom plate 103, the cover lens 108, and the ring 110 regardless of day or night, causing problems such as short circuits. .
2. Rainwater infiltrates into the inside from the hole 118 portion of the mounting bolt 104 that attaches the bottom plate 103 to the mounting plate 101, and in this case also troubles such as a short circuit occur.
3. Since a twisted wire is used for the power supply lead wire 114 of the LED 106, rainwater permeates into the socket receiver 113 due to the capillary phenomenon, causing troubles such as a short circuit. The present invention is provided in view of the above-mentioned drawbacks, and its purpose is to open the cover lens and perform repairs or replace parts when trouble occurs in the cover lens. It is possible to provide a marker lamp having a structure capable of completely preventing rainwater from entering.

In order to achieve the above object, according to the first aspect of the present invention, in the marker lamp, the resin bottom plate and the resin cover lens are detachably screwed with a spiral screw, and the joint surface between the bottom plate and the cover lens is waterproofed. Attached means,
A power supply terminal for supplying power to the light emitter so as to penetrate the bottom plate is attached, and a waterproof means is attached between the power supply terminal and the through hole of the bottom plate,
The mounting bolt for mounting the bottom plate to the mounting plate on the track side is mounted from the inside to the outside of the bottom plate, and waterproof means is mounted between the mounting bolt and the through hole of the bottom plate,
A vent hole communicating with the inside of the cover lens is formed in a part of the bottom plate, and an internal pressure adjusting means for preventing the intrusion of rainwater can be attached to the vent hole. thing,
It is characterized by.
According to this device, when a trouble occurs in the interior, the cover lens can be removed for repair or replacement of parts, and the dew condensation can be prevented by ensuring complete waterproofing and ensuring air permeability.

Furthermore, in the device according to claim 2, in the marker lamp according to claim 1, a nonwoven fabric is used for the internal pressure adjusting means.
With this device, air permeability can be secured while waterproofing.

  Further, in the invention according to claim 3, in the marker lamp according to claim 1, the internal pressure adjusting means includes a check valve made of rubber or a check valve that opens when the internal pressure exceeds a certain value by a spring. It is characterized by being used.

  Furthermore, in the device according to claim 4, in the marker lamp according to claim 1, a plate-shaped, prismatic or cylindrical terminal is used as the power terminal. is there.

  Further, in the device described in claim 5, the marker lamp according to claim 1 is characterized in that an LED is used as the light emitter.

The marker lamp according to the present invention is attached to the mounting plate 102 on the vehicle body 100 side using mounting bolts and nuts, as in the conventional example shown in FIG. The bottom plate and the cover lens are made of resin, and both are detachably screwed with a helical screw. As a result, when a trouble occurs inside, the carber lens can be removed for repair or replacement of parts.
In addition, since the waterproof means is attached to the bottom plate and the cover lens, the bottom plate, the terminal portion, and the mounting bolt portion, there is no fear that water, dust or the like will enter the inside.

  In addition, the bottom plate is provided with an internal pressure adjusting means, and prevents air from entering while preventing rain from entering, so that no condensation occurs inside.

  Due to the rainwater intrusion preventing effect described above, troubles such as a short circuit can be prevented, and dust prevention and rust prevention can be achieved.

An embodiment of the present invention having the above-described configuration and operation effects will be described in detail with reference to FIGS.
