JPS601043A - Demounting structure of blind cover - Google Patents

Abstract

PURPOSE:To facilitate demounting of a blind cover by forming the inclined surfaces at the both edges on the back surface of the blind cover body where hooks are not engaged and forming the cut parts for releasing engagement onto one- side surface on the hook engagement side. CONSTITUTION:A square hole 4 having stepped parts 4 formed on the whole outer peripheral edge is formed onto a panel 3. The hooks 2a and 2b for the engagment onto the upper and the lower inner edges which are opposed each other on the square hole 4 are installed onto the back surface of a blind cover bocy 1. The inclined surfaces 5a and 5b are formed at the right and left edges onto which the hooks 2a and 2b are not engaged, and the cut parts 6a and 6b for releasing the engagement of hooks are formed on the half side of the upper and the lower inner surfaces of the square hole 4 where the hooks 2a and 2b are engaged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a structure for removing a blind cover that closes holes formed in various panels.

[Prior art]

For example, the structure of a conventional blind lid is shown in Figures 1 (a) and (b).
There is something like the one shown in 0, that is, on the back side of the blind lid body/, two upper and lower claws 2a, 2b are protruded, and the blind lid body/is pushed into the rectangular hole made in the panel 3. The claws 2a and Jb are locked to the upper and lower inner edges of the square hole, so that the blind cover body can be attached to the panel 3 in a closed state with the hole 4t closed with one touch. A stepped portion 4ta is formed on the outer circumferential edge, so that when the blind lid body is completely pushed into the square hole, the outer surface of the blind lid body is flush with the outer surface of the panel 3.

For example, in a car, the blind lid is
Finisher attached to the panel (corresponding to panel 3)
That is, this rectangular hole is normally closed with a blind cover, but when optional equipment is installed, the blind cover must be removed and opened when the operating switch is installed.

However, in such a conventional % structure, the claw 2
It is a one-touch system using a, 2b, and there is no finger rest on the surface of the blind lid body/, so once the blind lid body/ is fitted, the blind lid body/ will be firmly attached to the panel 3. However, if you try to forcefully pry it open using a screwdriver or the like, you will damage the edges of the rectangular hole in the panel 3.

[Purpose of the invention]

The present invention was made in view of such conventional problems, and an object of the present invention is to provide a blind cover removal structure that allows the blind cover main body to be easily removed without damaging the edges of the rectangular hole of the panel. .

[Structure of the invention]

In order to achieve this object, the present invention has a rectangular hole with a step formed on the outer edge of the entire periphery, and a rectangular hole with a step formed on the outer edge of the entire periphery, and a rectangular hole that is fixed to the two opposing inner edges of the rectangular hole on the back surface of the blind lid main body. In the structure in which two claws protrude, slopes are formed at both ends of the back surface of the blind lid body where the mold is not locked, and +kj on the side where the claws of the square hole are locked. A notch for releasing the pawl lock is formed on each side.

[Action of the invention]

If the blind lid main body is slid laterally with one end floating, the pawl will be positioned in the pawl lock release notch and the lock will be released.

〔Example〕

The present invention will be explained below based on the drawings.

FIG. 2 fat l (b) I (C) l (d) is a diagram showing a practical example of the present invention.

In addition, two parts that are the same as before are given the same symbols ○ The basic structure of the present invention is conventional.

That is, the panel 3 is provided with a rectangular hole with a step a formed on the outer edge of the entire periphery, and on the back side of the WH main body, two claws are engaged with the upper and lower inner edges of the rectangular hole that are opposed to each other. 2
a, 2t) are provided protrudingly.

In this structure, the present invention forms inclined surfaces ja and jb on both the left and right sides of the back surface of the blind lid body where the claws 2a and 2b are not engaged, respectively, and also forms slopes ja and jb in the square hole. 'i4 Ih' There is a notch for releasing the claw on each half of the upper and lower inner surfaces ≦ &, 4'
form b.

Following this configuration, when removing the blind lid body in the closed state, first hook your fingernail (or a thin plate) on the right end of the blind lid body as shown in FIG. 3(a). Lift the end in the direction of the arrow. In this state, as shown in Figure 3(b), use your other fingers to press the right end of the blind lid body (
? Press in the direction of

In this way, the blind lid main body/moves with a slight inclination, and the claws 2a2.2. b slides along the upper and lower inner edges of the square hole. At this time, both sides of the blind lid main body are tilted a, j.
b also scratches the outer edges of the stepped portions a:to and right (1:tll) at the upper and lower edges of the square hole, respectively.

Then, as shown in Fig. 3 (C), when the claws λa, λb reach the claw locking and releasing cutouts ga, gb, the claws λa, 2b
The i-type city is removed and the blind cover body can be removed as shown by the arrow.

In this way, the blind cover body/can be easily removed, but at this time, no excessive force is applied to the edge of the rectangular hole in the first cover body/panel 3, so that they will not be bent. Since the installation of the main body is the same as before, it will be omitted.Furthermore, in the above embodiment, the inclined surface
, jb and the notches 4a++<b are formed on the left and right sides of the cover body and on the top and bottom of the rectangular hole, respectively, but they may be formed on the top and bottom and on the left and right sides, respectively. In this case, the claws 2a and λb of the blind cover body/are also provided on the left and right sides.〇 [Effects of the Invention] As explained above, according to the present invention, the edges of the rectangular hole of the panel can be easily removed without damaging the edges. It has a one-touch installation system with a blind lid that can be removed or removed.
