Description

[Detailed Description of the Invention] The present invention is an improved lamp that can be easily and quickly attached to, for example, a flash lamp that is attached to the surface of an automobile body so that it can be removed if necessary. This relates to the type of mounting structure.

For example, when it comes to installing side flush lamps on automobiles, there are conventional methods commonly used as shown in FIGS. 1 and 2.

The example shown in Figure 1 is a case where a lamp is attached to the panel surface of the body using a screw holder.A synthetic resin screw holder 3 is fitted into a square hole 2 drilled in the panel 1, and then this While aligning the screw receiver 3 and the insertion hole 4, the through hole 5 of the panel and the mounting through hole 6 of the socket (not shown), place the lamp mounting board 7 on the panel surface, and then attach the lens body to this board. The method shown in FIG. It is equipped with a cylindrical part 11 to which the cylindrical part is attached, and an L-shaped locking hook piece 12 on one side sandwiching the cylinder part, and a locking spring piece 1 made of a metal spring on the other side.
3 facing backward, and hook the locking hook piece 12 into the recess 15 formed at the edge of the mounting hole 14 opened in the panel 1 of the body, and then hook the locking hook piece 12 into the other recess 16 using the spring property. This is a case where the locking spring piece 13 is pushed in and locked into place.

Among these conventional methods, in the case of the former shown in Fig. 1, it is necessary to open multiple mounting holes in the panel 1 and the number of parts is large, making the assembly complicated and lacking in workability. There was a drawback that the parts were exposed and spoiled the appearance.

On the other hand, the latter method improves installation workability,
Although the defects in appearance have been improved, the metal locking spring piece must be separately processed and assembled, and the locking spring piece may rub against the edge of the mounting hole 14 during installation. There were problems such as damage to the painted surface, which caused rust and staining of the body surface.

The present invention has been developed in view of the various problems with conventional lamps, and has improved them, particularly in terms of workability and
This system was devised for the purpose of improving aesthetics, rationality in terms of management, etc., and its structure, operation, and effects will be described in detail below based on the embodiments of the invention shown in FIGS. 3 to 10.

FIG. 3 is an exploded perspective view of the flasher lamp according to the present invention seen from behind, and FIG. 4 is a partially sectional plan view showing the installed state.

The box-shaped lens body 20 is integrated by fitting the peripheral edge of a plate-shaped mounting board 21 into an opening and welding it to form a housing for housing a light bulb 22.

Like the lens body 20, the mounting board 21 is made of synthetic resin, and a cylindrical fitting body 23 projecting like a boss is integrally provided at the center of the back surface of the board.

The fitting body 23 is attached to a mounting hole 25 formed in a panel 24 of the body, which will be described later, to fix the board and also to hold a socket 26 for a light bulb. It has a pair of locking pieces 27, 27 provided so as to protrude in the direction, and an elastic clamping piece 28 for holding the socket 26 on the inner peripheral surface of the tip opening.

The locking piece 27 has a base end on the distal end side of the fitting body,
Using this as a base point, the tip facing the back of the mounting board can be bent inward, and this bendable tip gradually thickens from the base end, making the outer circumferential surface a tapered surface. At the same time, a step 29 is provided at the tip (see FIG. 6).

In the figure, reference numeral 30 denotes a frame-shaped gasket made of an elastic material. After the lens body 20 is fitted to the mounting board 21 and integrated, it is fitted to cover this fitting part, and When attached to a panel 24, which will be described next, it closes the gap with the panel surface and protects the painted surface of the panel.

On the other hand, the mounting hole 25 opened in the body panel 24 is a circular hole with a slightly larger diameter through which the fitting body 23 described above can be passed. A first notch 31 and a second notch 32 forming each pair are provided.

As shown in FIG. 9, these two sets of notches face each other on two straight lines that intersect at the center of the through hole, and one pair of first notches 31,
31 is deeper than the other second notch 32, 32, and the distance x between the depth edges is the same as that of the fitting body 2.
The opening width is larger than the distance w between the most protruding ends of the locking pieces 27, 27 of No. 3, and the opening width is larger than the horizontal width of the locking pieces 27. Then, the other notch 32, 3
The distance y between the two mutually deep edges is formed to be smaller than the distance w.

The lamp of the present invention configured in this way has a mounting board 2.
1 and the lens body 20, and the packing 30
In the actual work of attaching the light bulb 2 to the body, the light bulb 2 is inserted into the socket 26 from behind the fitting body 23 into the opening.
2 facing up and inserted into the lens body through the inside, the socket 26 is forcefully inserted and held between the clamping pieces 28 provided at the opening of the fitting body by utilizing the elasticity of the clamping pieces 28.

After installing the light bulb in this way, the fitting body 23
facing the mounting through hole 25 from the front, first attach the locking piece 2.
7 and 27 are aligned with the direction of one notch 31 of the through hole.

FIG. 10A shows this state, and after alignment, the locking piece 27 is made to protrude to the back side of the through hole 25 through the notch 31. After that, when the fitting body 23 is rotated 90 degrees inside the hole in this state, the locking piece 27 is forcibly bent inward by the edge of the hole 25 and moves along this edge. Rotates in sliding contact with the guide, faces the second notch 32,
It engages in this notch by the action of restoring force (see FIG. 10B).

When the fitting body 23 is inserted into the mounting hole 25 and the back surface of the mounting board 21 comes into contact with the surface of the panel 24, the locking piece 27 passes through the step part 29 at the tip to the back side of the hole, and A protruding piece 27' protruding from the tip is made to face the edge of the tip, and during rotation, this protruding piece 27' slides into contact with the edge, and when the notch 32 is engaged, this notch The stepped portion 29 is brought into contact with the inner surface of the deep edge of the notch to ensure engagement with the edge.

The lamp body installed in this way is attached to the locking piece 2.
7 engages in the notch 32 of the mounting through-hole 25, making it impossible to pull out, and the rotation of the fitting body 23 during installation is prevented by the above-mentioned engagement, so that a stable mounting state is obtained. . When it is necessary to remove the mounting board 21, for example to replace a light bulb, if the mounting board 21 is forcibly rotated against the rotational restraining force,
The locking piece 27 that has engaged in the notch 32 bends inward due to its elasticity and comes off the notch, so it moves again to the first notch 31 and is aligned with it, thereby locking. Once the mating state is released, it can be pulled out from the through hole 25 as it is.

As explained above, the structure of the present invention is simple, and each part, especially the main parts, the mounting board and its fitting body, can be integrally molded from synthetic resin, which is advantageous in terms of manufacturing. Since the fitting can be installed by inserting the fitting into the mounting hole and rotating it, the workability on the assembly line can be expected to be significantly improved compared to the conventional example.
Even if it is necessary to remove it for maintenance and inspection, it has the advantage that it can be easily removed while retaining its original shape by applying some rotational force.

Moreover, since the mounting state on the panel is hidden behind the lamp body and cannot be seen from the outside, it is aesthetically pleasing, and since hard materials such as metal are not used in the engaging parts, there is no risk of damaging the paint film on the panel surface. Therefore, it does not cause rust and is extremely convenient.

Incidentally, the orientation of the above-described locking piece and the cutout portion of the mounting hole for locking the locking piece may be arbitrarily determined depending on the orientation of the lamp body when it is mounted.

Of course, in the embodiments, the flash lamp was explained as an example, but it is unnecessary to explain that the present invention can be applied to attaching other lamps.
