DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch knob mounting structure installed in a portable remote controller, which is a keyless entry transmitter for an automobile.

[0002]

2. Description of the Related Art A conventional switch knob mounting structure for a portable remote controller or the like is shown in FIG. 5, for example. The specific structure is as follows. In FIG.
Are a pair of case members which are joined to each other at the opening and have a slit 3 at this joint portion to form a case 4. The slit 3 penetrates into and out of the case 4 in the vicinity of a switch knob mounting portion described later.

[0005] Reference numeral 5 denotes a pair of case members 1 and 2.
A notch formed at the joint portion and penetrating into and out of the case 4 is fitted into the notch 5 to turn on / off a switch (not shown) installed in the case 4. It is.

[0004] Reference numeral 7 denotes a switch flange integrally provided with the switch knob 6 for preventing the switch knob from dropping, so as to be located inside the case components 1 and 2 around the notch 5. In FIG. 5, it is shown by a dotted line. Reference numeral 8 denotes a key body which constitutes the tip of the key, is provided with a key groove, and is a rod antenna for transmission.

FIG. 6 is an enlarged perspective view showing the switch knob 6. The switch knob 6 has a rectangular plate shape as a whole, and the upper surface thereof is a keyless entry transmitter for an automobile. A figure 9 such as a vehicle is designed.

On the other hand, on the lower surface of the plate body forming the switch knob 6, the rectangular switch flange 7 having an area sufficiently larger than the area of the plate body is integrally formed. Further, a switch that is turned on or off by a push operation of the switch knob 6 is provided in the case 4.

Therefore, in such a switch knob structure, the switch is turned on, for example, by turning on the switch 4 by grasping the case 4 with a hand and pushing the switch knob 6 with a finger, thereby supplying power to the circuit in the case. And allow transmission.

On the other hand, a switch flange 7 is provided on the switch knob 6, and the switch 4 is operated by the switch itself operated by the switch knob 6 to receive the return elastic force.
During the return operation to the outside, the removal of the switch knob 6 and the switch flange 7 from the notch 5 is restricted.

The slits 3 formed at the joints of the case members 1 and 2 function so as to make the displacement of the edges of these joints in the combination of the case members 1 and 2 inconspicuous. .

[0010]

However, in this conventional switch knob mounting structure, the switch flange 7 inside the case members 1 and 2 is seen through the slit 3 near the notch 5 from the outside. If the switch flange 7 and the case components 1 and 2 have different color tones, for example, the design of the portable remote controller as a whole may look unnatural and unfavorable.

The present invention has been made in view of such a conventional problem. A switch flange integrated with a switch knob is prevented from being seen through a slit from the outside of a case structure, and the vicinity of the slit is reduced. An object of the present invention is to provide a switch knob mounting structure that can improve design and enhance quality.

[0012]

A switch knob mounting structure according to the present invention comprises a pair of case members forming a case having a slit in a joint portion, and a joint formed between the pair of case members. A notch, a switch knob for turning on and off a switch installed in the case, and a switch knob integrated with the switch knob, which is provided inside the case components around the notch. A switch flange for prevention, wherein a slit larger than the slit width is formed in the switch flange.

[0013]

According to the switch knob mounting structure of the present invention, a switch flange integral with the switch knob is provided inside each case body and faces a slit at these joints. Also, by providing a slit larger than the slit, the slit flange is made invisible from the outside of the case through the slit on the joint portion side.

[0014]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 shows an embodiment of the present invention. In the figure, reference numerals 1 and 2 denote a pair of case members which are joined to each other at an opening to form a case 4 having a slit 3 at the joint.

A notch 5 is formed at the joint between the pair of case members 1 and 2 and penetrates the inside and outside of the case 4. A notch 6 is fitted into the notch 5 and inserted into the case 4. A switch knob for turning on and off a switch (not shown) to be installed.

Reference numeral 7A denotes a switch flange provided integrally with the switch knob 6 for preventing the switch knob from dropping out so as to be positioned inside the case components 1 and 2 around the notch 5. 1 is indicated by a dotted line. Reference numeral 8 denotes a transmission rod antenna having the same function as that of FIG.

The switch flange 7A has a slit 11 as shown in FIG.
Is formed. The slit 11 is formed to be larger than the width of the slit 3 so that the switch flange 7A inside the case 4 cannot be seen from the outside through the slit 3.

Therefore, when the width of the slit 3 is a and the width of the slit 11 is b, the dimensions a and b are appropriately selected under the condition of b> a.

FIGS. 3 and 4 are sectional views taken along the line AA in FIG. 1 and BB showing the vicinity of the switch knob 6 in detail.
It is a line sectional view. As shown in each of these drawings, a switch flange 7A integrated with the switch knob 6 is inside the case body 2, and the slits 3 and 11 are opposed to each other.

A switch 12 is provided at the center of the lower surface of the switch knob 6, and this is connected to an operator 14 of a switch 13 installed in each of the case members 1 and 2.
3 is in contact with a waterproof cover 15 made of silicon rubber which covers 3 and the like.

Next, the operation will be described. First, for example, the case 4 constituting the portable remote controller is grasped by hand, and the switch knob 6 is pushed by a finger.

Thus, the protrusion 12 on the lower surface of the switch knob is provided.
Presses the operating element 14 of the switch 13 via the projection 15a which is a part of the waterproof cover 15.

For this reason, the switch 13 operates to put the electric circuit in the ON mode, for example, to supply power to each circuit in the case 4 and to output a transmission radio wave.

On the other hand, the switch knob 6 is provided with a switch flange 7A so that the switch operated by the switch knob 6 can be returned to the outside of the case 4 by the return elastic force of the switch itself. The removal of the switch knob 6 and the switch flange 7A from the notch 5 is restricted.

Since the switch flange 7A is formed with the slit 11 wider than the slit 3 at the joint of the case components 1 and 2, the switch flange 6A is operated even when the switch knob 6 is operated. This makes it impossible for the switch flange 7A to be seen from the outside of the case 4 through the slit 3 around the notch 5.

Therefore, even if the switch knob 6 and the switch flange 7A and the case members 1 and 2 constituting the case 4 have greatly different colors, the difference in the colors cannot be recognized. The design does not become unnatural, and a high quality feeling can be maintained.

[0027]

As described above, according to the present invention, a pair of case members forming a case having a slit at a joint portion, a notch formed at the joint of the pair of case members, and Turn on the switch installed in the case,
A switch knob to be turned off, and a switch flange integrally provided with the switch knob for preventing the switch knob from being dropped so as to be located inside each of the case members around the notch. Since the slit is formed so as to be larger than the slit width, the switch flange of the switch knob can be prevented from being seen through the slit from the outside of the case structure, and the design in the vicinity of the slit is improved, and the sense of quality is improved. There is an effect that something that can be enhanced is obtained.
