Description

[Detailed Description of the Invention] The present invention relates to a vehicular lamp, and more specifically, to a vehicular lamp in which a lens is disposed in a housing via a gasket.

As shown in FIG. 1, a conventional vehicular lamp of this type has a housing a with a gasket b attached to the peripheral edge thereof, and a lens c disposed on the housing a via the gasket b. When attaching the seal b to the periphery of the housing a, as shown in FIG. 2, positioning pins e are raised and protruded at predetermined positions on the periphery of the housing a, as shown in FIG. A half-moon-shaped protruding piece f is attached to the inner circumference of the packing b.
At the same time, by providing a hole g in the protruding piece f that matches the positioning pin e, and passing the positioning pin e through the hole g, it is possible to accurately position the gasket b with respect to the housing a without turning it over. That's what I do. Then, by bringing the peripheral edge of the lens c into contact with the gasket b provided on the housing a and attaching the lens c to the housing a with bolts or the like, the gasket b seals between the lens c and the housing a. That's what I do.
Note that in FIG. 1, d represents a valve.

By the way, the conventional vehicle lamp has a housing a
When the lens c is assembled to the lens c, when viewed from the front, the protruding piece f of the gasket can be seen through the lens, especially if it is made of natural rubber, and not only does it give a strange feeling.
Since the positioning pin e of the housing a is located in the center of the protruding piece f, the positioning pin e appears to be floating, which has the disadvantage of spoiling the appearance.

In addition, when assembling the seal b to the housing a, if the pin e of the housing a and the hole g of the protruding piece f of the seal b are aligned, the elastic force of the seal b will cause the protruding piece f to conform to the pin e. difficult,
The seal b may come off the pin e, so if you assemble the lens c into the housing a without noticing the condition of the seal b,
There is a problem that the sealing performance between the two deteriorates.

In view of the above circumstances, the purpose of the present invention is to provide a vehicle that can reliably assemble the gasket to the housing, maintain good sealing between the housing and the lens, and that does not cause damage to the exterior appearance. The purpose is to provide lighting equipment.

An embodiment of the present invention will be described below with reference to FIGS. 4 to 11.

As shown in FIG. 4, the vehicle lamp of the embodiment has the following features:
A gasket 2 is attached to the peripheral edge 11 of the housing 1, and a lens 3 is attached to the peripheral edge 11 of the housing 1 via the gasket 2 with bolts or the like.

A gasket 2 is provided on the peripheral edge 11 of the housing 1.
The mounting part 21 should be protruded forward to position the
is formed. More specifically, as shown in FIGS. 5 to 8, the mounting portion 12 is formed so that a part of the outer peripheral edge 11a of the peripheral edge 11 faces forward with an appropriate width and height. A rising wall 12a formed by raising the wall 12a, and a bent portion 11 of the inner peripheral edge 11b at the tip of the rising wall 12a.
The extension walls 12b have a cross-sectional shape extending up to c, and are arranged in an appropriate number at predetermined intervals on the periphery.

Each of the mounting portions 12 is provided with an insertion hole 13 that is bored laterally and communicates the front side and the back side of the peripheral edge portion 11. The insertion hole 13 is connected to the upright wall 12a of the mounting portion 12.
The extension wall 12b is penetrated with a dimension smaller than the inner width dimension of the extension wall 12b, and communicates the front side and the back side of the peripheral edge part 11.

On the other hand, a locking protrusion 21 is formed on the packing 2 at a position corresponding to the mounting portion 12. The locking protrusion 21, as shown in FIGS. 9 to 11,
A neck portion 21a is formed inward on the inner peripheral portion of the front wall 22 of the packing 2 and has a size corresponding to the insertion hole 13, and a tapered portion is formed at the tip of the neck portion 21a to extend further inward. It has an arrowhead portion 21b in the shape of an arrow, and an inclined surface portion 21c formed on the back surface between the arrowhead portion 21b and the neck portion 21a by gradually increasing the thickness from the tip of the arrowhead portion 21b to the neck portion 21a. There is. This locking protrusion 21
When the neck part 21a is inserted with its tip into the insertion hole 13 of the mounting part 12, the arrowhead part 21b is attached to the mounting part 12, and the inclined surface part 21c is attached to the outer peripheral edge part 11a.
The arrowhead portion 21b and the inclined surface portion 21c are positioned on the back surface of the peripheral edge portion 11.

Note that a locking protrusion 2 is provided on the rear wall 23 of the packing 2.
The inclined surface part 2 of the locking protrusion 21 is located at the position corresponding to 1.
A notch 24 is provided to prevent contact with 1c. In FIG. 4, 4 is a valve and 5 is a socket.

The vehicle lamp according to the embodiment has the above-described configuration. Therefore, in order to assemble the gasket 2 to the housing 1, first, the locking protrusion 21 of the gasket 2 is inserted into the mounting portion 12 provided on the periphery of the housing 1. When inserted into the insertion hole 13, the arrowhead portion 21 of the locking protrusion 21
b passes through the insertion hole 13 to the back side of the mounting part 12,
That is, it is located on the back side of the peripheral edge part 11. At this time, since the arrowhead part 21b of the packing 2 is locked to the mounting part 12 and the inclined surface part 21c is locked to the peripheral edge 11, the packing 2 is attached to the peripheral edge of the housing 1.
It is possible to position the object reliably without falling through. As a result, by fitting the seal 2 to the peripheral edge of the housing 1, it can be reliably assembled, so when the lens 3 is assembled to the housing 1,
The space between the two can be reliably sealed by the gasket 2.

Furthermore, even if the locking protrusion 21 protrudes inside the gasket 2, it is located on the back side of the housing periphery 11, so when the lamp formed by assembling the lens 3 to the housing 1 is viewed from the front, the gasket 2 is There is no possibility that the locking protrusion 21 can be seen through. Moreover, since the mounting part 12 formed on the housing 1 is finished in the same color as the inner surface of the peripheral part 11, unlike the conventional case in which the positioning pin e is located inside the protruding piece f, it does not appear to be floating. It's not unsightly at all.

Further, in the illustrated example, the locking protrusion 21 of the seal 2 extends between the neck portion 21a and the arrowhead portion 21b, and the slanted surface portion 2
1c, the inclined surface portion 21c not only increases the locking force of the arrowhead portion 21b to the attachment portion 12, but also reinforces the locking protrusion 21 itself, so that it can have sufficient strength.

As described above, in the present invention, an appropriate number of attachment portions are formed on the peripheral edge of the housing so as to protrude forward, and each of the attachment portions is bored laterally and connected to the front side of the peripheral edge. An insertion hole communicating with the rear side is formed, and a locking member is inserted into the insertion hole of the attachment part at a position corresponding to the attachment part of the packing and is locked to the attachment part, and can be located on the rear side of the peripheral edge of the housing. Since the locking protrusions are formed respectively, the seal can be reliably assembled to the housing without coming off, and as a result, good sealing between the housing and the lens can be maintained. Since it is located on the back side of the peripheral edge, the packing will not be visible when the lamp is viewed from the front, so there is no risk of spoiling the appearance.
