Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to a lamp body, a rim, a lens, etc., which are in contact with an automobile body pipe, a lamp body, a rim, a lens, etc. This relates to an automotive lamp that is integrated with end rubber or foil.

[Prior art]

Generally, an end rubber is attached to the end edge of the lamp body that comes into contact with the vehicle body panel, for the purpose of preventing the lamp body and the vehicle body panel from interfering with each other. A prior art structure in which En1-rubber is bonded to the edge of the lamp body is shown in Figure 9 (C
) and as shown in FIG. 10(c), En 1 to Rubber 2 are adhesively integrated with the end edge 7 of the lamp body 6 via both mI contact tape 4 and contact agent. Are known.

Figures 91(a), (b), (c) and Figure 10(a)
, (+)), and (c) are diagrams illustrating the procedure for manufacturing a conventional automobile lamp with end rubber bonded, that is, the procedure for bonding Ens. 1 to 8 to the edge of the lamp body. . As shown in FIG. 53(a), a release paper 3f is placed on the joint surface 2a of the rubbers 1 to 2 with the lamp body 6.
・Put the names of both interviews on tape No. 1. Then, as shown in FIG. 10(a), the release paper 3 is exposed at J3'a field to expose the viscosity of the tape (see FIG. 9(b)). Press the adhesive side against the edge 7 of the lamp body and attach the rubber parts 1 to 2 to the lamp body 6.
Paste it on.

The process of pasting this En 1-Rubber 2 is shown in Figure]-〇(
l]). In addition, as shown in FIG. 40 (0), an opening 5 is provided in one direction of the end 1 - the length of the rubber - J (inside the end rubber 2 is provided with an opening 5).
After pasting, adhesive is poured into the bonding surface through the opening 5 to ensure adhesion between the runsi body 6 and the end rubber 2.

[Problem to be solved by the invention]

However, in the prior art described above, it is not necessary to apply double-sided adhesive tape 4 to the end rubber 2, and it is necessary to remove the release paper 3 when assembling the end rubber 2. There is also the problem that it is necessary to inject a tape adhesive of 1 + 1 (1Il) (I am not sure about the adhesive strength; 1Il), which requires a lot of man-hours and is troublesome. Ta.

I'm also thinking of gluing the En-1 Hera Bar only with adhesive gullet without using double-sided adhesive tape.
For example, 1 cps of adhesive used in the past is 3 cps of sticky melon.
Since it is a relatively quick-drying adhesive with a hardening time of 3 to 15 seconds and very little viscosity, the adhesive may protrude from the bonded surface when assembling the En1 Hera Bar to Runshibotie. It was very inconvenient to handle, as there were problems such as it being undesirable and dangerous as it could jump off. .

The present invention has been made in view of the problems of the prior art described in j) and b.The first object of the present invention is to provide an automobile lamp with good workability for adhering rubber to lamp component members.

[Means for Achieving θζ to Angularize the Correction Emission] In order to achieve the above-mentioned IJ objective, in the automobile lamp according to the present invention, a self-propelled member that is in contact with the vehicle body panel, Ensemble 1 on the edge of the lamp component of the rim and lens ζ9.
- In an automobile lamp in which rubber is bonded, the en-1 rubber and the fishing gear component material are bonded together using a jelly-like adhesive.

[Function J] Since the adhesive that connects the end rubber and the lamp component is jelly-like, the adhesive can be applied to a fixed area without any dripping or dripping. It becomes difficult for the adhesive to protrude outside the joint when the two are joined together. Also, there is no splashing of the adhesive when gluing En1-rubber.Also, since the adhesive has a certain degree of fluidity, The adhesive is smoothly discharged from the dispensing device. Also, by suppressing the rubber and the lamp components, the adhesive becomes uniformly thick on the joint surface.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Figures 1 to 311! ! 1 is an embodiment of the present invention shown in "Moondust Diagram-C1". The figure is a perspective view of the end rubber that is attached to the run body of an automobile lamp, Figure 2 is a sectional view taken along line 1l-II shown in Figure 1, and Figure 3 is the run body and end of the automotive light. It is a cross-sectional view of the 11° part of the rubber.

In these figures, the reference numeral 10 denotes an en [-rubberte, fire J',! It has a shape that can be placed along the edge part 13 of the lalambutity 1, which is L't+'; Then, the end edge 13 of Runshiboti] 2 is bonded with adhesive through rubber, and when it is assembled into a large lug or an automobile body, this end Rubber"-〇 or the vehicle body panels 16 are in contact with each other, and the vehicle body panels 16 are kept at a distance of 10 m from each other.

Adhesive 1-4 for adhering rubber 1-〇 to the edge of Runsibotie 3 is in a jelly state or J3.For example, Aron Alpha GEL manufactured by Toagosei Chemical Industry Co., Ltd. 1.0 (viscosity J-70000 cps, curing time 15 seconds).

Next, attach the en 1 rubber bar 10 to the end of the lamb body, μ section:
3 will explain the procedure for bonding and integrating.

First, as shown in FIG. 1, apply adhesive to the adhesive part 11 of the end 1 to the rubber 10 with the end edge 13 of the lamp body at a constant pitch or along a line along the extending direction of the end rubber. 2. Apply at a predetermined pitch in the figure. The adhesive 1/] is in the form of a jelly, and can be smoothly dispensed from a dispenser to uniformly apply it to a predetermined area. I applied this adhesive] 4 to the blower (~rubber) 0
Hold it and align it to position 3 on the edge of the lamp body.

This assembly method is En1~Rubber -M:lj
Align the section with the edge of the lamp body and assemble it (=j
Mark 11 for JZ positioning on the rubber and the end edge of the lamp body. Attach the rubber bar 10 to the edge of the lamp body"-;3
When attaching XJl (when putting it together, press 1~rubber) Q is work, t) Since it is sufficiently longer than l, press the rubber while keeping the surface where the adhesive 14 is applied with water. It is difficult to glue the lamp body to the lamp body, and the installation process is difficult.
<The rubber 10 is now tilted in the direction of the persimmons. At this time, if the viscosity of the adhesive 14 is too small, the adhesive may drip and flow, leaving a stain on your hands or clothes, making it inconvenient to handle. Since 1-14 is jelly-like, there is no problem like this even if you turn it upside down.
It is easy to handle, and the brackets 1 to 10 can be smoothly assembled to the lamp body edge 13, making the work easy. .

The way to attach this end rubber is, for example, by pinching the joint surface between the end rubber and the end edge of the lamp body with your fingers along the periphery of the lamp body. All you have to do is press it against the end edge 13 of the lamp body. Note that since the adhesive [4] is jelly-like or has moderate fluidity, the adhesive pressed between the en-1 rubber bar 10 and the lamp body edge 13 spreads to some extent on the joint surface, and the joint is broken. The thickness is approximately uniform over the entire surface. In addition, since adhesive] 4 has moderate viscosity,
It does not protrude outside the joint.

In addition, in the case of adhesive ↓ 4 or Aron Alpha GEL-10, it hardens in only about 15 seconds after being discharged from the dispensing device, so apply En 1 to Rubber 10 to the edge of the lamp body.
3, it can be bonded and integrated in a short time.

FIG. 4 shows a second embodiment of the present invention, in which four parts 10a are formed on the joint surface of the end 1 rubber bar 10 with the lamp body edge 13,
A convex portion 12a that engages with the concave portion 7 is formed on the joint surface with the rubber O.

and the concave part of the end rubber] - ○a 1 A celery-like adhesive 14 that is the same as the adhesive 14 used in the first embodiment above
Paint a 11, lamp body] 2 end rubber 1
It has a structure in which 0 and 0 are bonded together.

Since the adhesive 14a is applied to the four parts 102'' on the rubber side of the en-1 rubber, there is no need to worry about dripping even if the adhesive 14a is slightly smaller than the suffix 14 in the above-mentioned embodiment by %'+'i degrees. Therefore, there is an advantage that there is room for selection of adhesives ↓4a that can be used, that is, the allowable range of viscosity of adhesives J and 4a is correspondingly wider.

FIG. 5 shows a third embodiment of the present invention-C, en 1
- 1 engagement of rubber 10 with lump 0 body 12; Then, an adhesive 14a is applied to the area surrounded by the peripheral wall 10b, and a rubber 10 is bonded to the lamp body 12.This embodiment also has a structure similar to the previous V. This embodiment has the same effect as the second embodiment.

In addition, the above-mentioned 2. In the third embodiment, the protrusions 12a and recesses 12b on the lamp body side are formed into protrusions r'flf and grooves formed on the end edge of the lamp body, and the four parts 10a and the protrusions 10b on the end rubber side are formed into grooves. It may also be a concave portion or a convex portion extending in the direction in which the rubber extends.

Furthermore, in the second embodiment described above (see FIG. 4), four parts may be formed on the lamp body side, and a convex part may be formed on the end 1 (rubber side). 5
(see figure), a convex portion may be formed on the lamp body side, and a concave portion may be formed on the end 1 to rubber 1 side.

FIGS. 6 to 8 show diagrams of main parts IDi of still other embodiments of the present invention, and FIG. They have a U-shaped cross section and are prevented from being pulled out in the left and right direction in Figure 6, and the two are glued together through adhesive 14b applied to the inside of the rubber 10 and the rubber 10. It has a built-in structure. The adhesive 14b is the same jelly-like adhesive as the adhesive 14 used in the first embodiment.

In Figure 7, Fjf! In addition to the engagement structure between the lancibo eye and the en 1~rubber shown in FIG. and the engaging part that engages in the left-right direction in Figure 7], and has a structure that prevents removal in the left-right direction and the vertical blade direction in Figure 7, and
The structure is such that the two are integrally connected via the adhesive applied in the groove of the spatula bar 10 -4b.

In FIG. 8, an underwater recess 13 b 3 is formed on the root side of the end edge of the run body 12, which is not shown in FIG. 7, and is not shown in FIG. The horizontal protrusion on the lanciboai side by straightening the inner side edge of 〇]
Attach the rubber ○ to the lancibo eye 12 so that it contacts 3 b (when the J-shape is reached, the four parts 12 c are formed at the joint on the rambu hotty side, and the two parts are pulled out from each other in the upward direction 1 in Fig. 8). It has a closed structure.

Therefore, the adhesive 141) pressed against the joining surface enters into the four parts on the Ranciboai side ]2c, and since the adhesive 141] is jelly-like, the adhesive 14b or the adhesive 14b is pressed along the outer wall of the Ranciboai 12. There are no problems such as dripping.

The embodiment shown in FIGS. 6 to 8 has a recess 114 formed on the end rubber side in the extending direction of the end rubber, so it is similar to the second and third embodiments shown in +"Nf. The adhesive i4b may have a somewhat lower viscosity, and there is a wide range of options for selecting the most suitable adhesive.

In addition, in the embodiments shown in Figs. 61'A to 8, the En 1 - Rubber Soil Q and Lancibo Eye 12 have a structure that prevents them from being removed, so the adhesive is applied in the direction from En 1 to the Rubber side. Even if the amount is uneven, it is easy to manage the application of the adhesive because it prevents it from being removed and compensates for variations in adhesive strength at the engaging portion, so there is no need to strictly specify the amount of adhesive applied.

Generally, when attaching the En1 rubber to the edge of the Ransibo eye, after adhering the En1 to Rubber 0 to the edge of the Lanshibo eye -3, press the joint surface until the adhesive softens. In the state; ``Does it have to be held for a certain period of time? Since the structure is such that it can be separated even after adhesion, there is no problem.

In the above-described embodiments, the adhesive is applied to the end rubber side in all cases, but the adhesive may be applied to the lanciboai side, or it may be applied to both sides.

In addition, in the above embodiments, explanations have been given by taking as an example automobile fittings in which End Rubber is bonded to Lancibo Eye, and automobile fittings having End Rubber bonded to other fire fittings construction members such as Rimya Lens. It may also be a prop.

〔Effect of the invention〕

As is clear from the above explanation, the car fitting according to the present invention has a dent, since the end rubber and the KL fitting component are integrally connected by a jelly-like adhesive.
- There is no dripping of adhesive during rubber bonding work, and no adhesive protrudes outside the joint, so
Depending on the adhesive Jβ・X) Lights J that are clothes or products
It is easier to work as there is less chance of getting lost.
In addition, the incidence of defective products due to the appearance of the lamp is also low. In addition, there is no splashing of the adhesive when bonding the rubber, so I am trying to make the bonding work of the rubber safe. The adhesive has a jelly-like or moderate fluidity, so it can be discharged smoothly from the discharge device, and when it is compressed by the rubber and the lamp component, it spreads at the joint surface, creating a uniform thickness. This becomes adhesive Bj.

In this way, the tree design can significantly improve the proficiency and safety of en-1-rubber's entitlement system compared to conventional methods.
