Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for an automobile cigarette lighter.

As is well known, automobile cigarette lighters are attached to instrument panels.

The mounting structure generally employed in the past is as follows.

That is, insert the socket of the cigarette lighter into the mounting hole of the panel from the front of the panel, bring the collar provided around the upper end of the socket into contact with the periphery of the mounting hole, and
Most of the socket is made to protrude to the back side of the panel, a cylindrical case is placed on the protruding part on the back side of the panel, and the threaded bottom of the socket and the threaded bottom of the case are screwed together and tightened. The flange of the socket and the periphery of the upper end of the case sandwich the periphery of the mounting hole of the panel.

Since the conventional mounting structure is as described above, it is not possible to perform the mounting work only from the front side of the panel, resulting in poor work efficiency.

The present invention was developed in view of these conventional drawbacks, and provides a new mounting structure that can improve work efficiency by performing all mounting work on a cigarette lighter panel from the front of the panel. It is.

Embodiments of the present invention will be described below based on the drawings.

1 to 3 show a first embodiment.

In the figure, 1 is a holder for holding a cigarette lighter, and is composed of a first ring 2 and a second ring 3.

The first ring 2 is integrally constructed of a synthetic resin material and includes a collar 5 having a circular center hole 4 and a split cylindrical foot 6 connected to the inner surface of the collar 5 around the center hole 4. It becomes.

A socket insertion passage 7 is formed by the center hole 4 of the collar 5 and the inner surface of the foot 6.

The above split cylindrical foot 6 is composed of cylindrical feet 6 a and 6 b facing each other with cutouts 8 a and 8 b interposed therebetween.

An outer circumferential groove 9 is provided on the outer circumference of each leg 6 a , 6 b.

This outer circumferential groove 9 connects the inner surface 10 of the collar 5 and the legs 6 a and 6 b.
It is formed with a protrusion 11 provided in the circumferential direction on the outer peripheral end of the.

Further, a protrusion 12 is provided in the circumferential direction of the inner peripheral end of each leg 6a, 6b.
has been established.

On the other hand, the second ring 3 is formed by forming a band-shaped metal plate into a cylindrical shape, and a so-called split cylindrical shape with a gap W provided between both ends thereof.

The width dimension 11 is the foot 6a of the first ring 2.
, 6b is approximately the same as the width dimension 12 of the outer circumferential groove 9.

The second ring also includes two protrusions 13 cut and raised from the inside toward the outside.

The second ring 3 is fitted into the outer peripheral groove 9 of the legs 6a, 6b of the first ring 2 so as to be immovable in the axial direction of the first ring 2.

Now, the holder 1 assembled as described above is the panel 1
It is inserted from the front side of the panel 14 into the circular mounting hole 15 drilled in the panel 4 .

The diameter of the mounting hole 15 is approximately equal to the outer diameter of the second ring 3 fitted into the outer circumferential groove 9 of the first ring 2 .

When inserting the holder 1, the legs 6a, 6 of the first ring 2
When the protrusion 11 of b and the protrusion 13 of the second ring 3 pass through the mounting hole 15 of the panel 14, the legs 6a and 6b can bend inward, so the above insertion can be performed without any problem. .

Immediately before the inner surface of the collar 5 of the first ring 2 comes into contact with the front surface of the panel 14, the protrusion 13 of the second ring 3 comes out of the mounting hole 15, and the bent leg 6a of the first ring 2, 6
b returns to its original position, and the protrusion 15 is locked to the back surface of the panel 14.

In other words, this protrusion 13 has its upper part and the collar 5 of the first ring.
It is positioned so that the distance from the inner surface of the panel is approximately equal to the thickness of the panel.

Therefore, the panel 14 is clamped around the mounting hole 15 by the inner surface of the collar 5 of the first ring 2 and the protrusion 13 of the second ring 3, so that the holder 1 is securely attached to the panel 14. Fixed.

On the other hand, the socket is provided with a collar 18 on its outer periphery and a window 19 on its peripheral surface.

The outer diameter of the peripheral surface of the socket is configured to be slightly smaller than the diameter of the socket insertion passage 7 of the first ring 2.

Therefore, when this socket 17 is inserted into the socket insertion passage 7 of the first ring 2, the peripheral surface of the socket 17 pushes and spreads the legs 6a, 6b of the first ring 2, but when the insertion is completed, the legs 6a, 6 The protrusion 12 of b enters the window 19 of the socket surface, and the legs 6a, 6b return to their original positions.

Since the flange 18 of the socket contacts the flange 5 of the first ring 2, the socket 17 cannot be inserted any deeper.

Further, when a force is applied to the socket 17 in the direction of pulling it out from the first ring 2, the legs 6 a of the first ring 2
, 6b are locked around the window 19 of the socket, so that the socket 17 cannot be pulled out from the first ring 2.

Next, a second embodiment shown in FIGS. 4 and 5 will be described.

This embodiment is characterized in that the second ring 3 is attached to the inner peripheral surface of the first ring 2.

The legs 6 of the first ring 2 are formed into a cylindrical shape.

Inner circumferential grooves 9' are formed on the inner surface of the center hole 4 of the collar 5 and on the inner circumferential surface of the legs 6.

Furthermore, windows 16 are provided at two locations on the leg 6 to penetrate in the radial direction of the first ring 2.

The foot 6 has a protrusion 12 around its lower end as in the first embodiment, but the outer periphery of the foot is formed flush.

The configuration of the second ring 3 is basically the same as that of the first embodiment, but the degree of protrusion of the protrusion 13 is increased.

This second ring 3 is fitted into the inner circumferential groove 9' of the first ring 2.

At this time, each protrusion 13 projects outward from each window 16 formed in the leg 6 of the first ring 2.

When inserting the holder 1 consisting of the combination of the first ring 2 and the second ring 3 into the mounting hole 15 of the panel 14, the protrusion 13 of the second ring 3 protruding from the window 16 of the leg 6 of the first ring 2 When pressed by the inner surface of the attachment hole 15, the split cylindrical second ring 3 deforms and can be easily buried inside the window 16.

Therefore, the feet 6 of the first ring 2 are inserted into the mounting holes 15 of the panel 14 without any problem, and after insertion, the protrusions 13 of the second ring 3 are inserted into the windows of the first ring 2 again.
6 protrudes outward and cooperates with the inner surface of the collar 5 to sandwich the panel 14.

Similar to the first embodiment, the socket inserted into the socket insertion passage 7 of the first ring 2 is prevented from coming off by engagement between the protrusion 12 provided on the lower inner circumference of the leg 6 and the window 19 of the socket. .

As described above in detail in the first and second embodiments, the mounting structure of the automobile cigarette lighter according to the present invention includes a holder that can be inserted into the mounting hole of the panel from the front of the panel instead of the conventional socket mounting case. This makes installing the cigarette lighter much easier.

In addition, the above holder can be securely attached to the panel using two simple members, the first ring and the second ring.
Further, there is an advantage that panel thicknesses that vary depending on the type of automobile can be easily dealt with by simply changing the position of the protrusion of the second ring.
