Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door structure used in a housing of an electronic device or the like.

2. Description of the Related Art Conventionally, double-sided or single-sided doors have been used as hinged doors provided in housings of electronic devices and the like.

[Problems that conventional techniques and ideas attempt to solve]

Even when double doors are used, the left and right doors 1 and 2 may have different lengths as shown in FIG. 3 for reasons of maintenance of internal equipment. Even in such a case, a handle 3 for opening and closing is required as in the case of a normal double door, and this poses a problem in that it is unfavorable in terms of appearance as an electronic device housing.

[Means for solving problems]

The present invention provides a door structure for a housing that solves the above-mentioned problems.
In a case having a single-swinging door at the opening, the door consists of a main door shorter than the length of the opening and a movable plate provided at the free end side of the main door, and the movable plate is bent at the tip. The main door and the movable plate are arranged in a straight line or in a straight line. A toggle spring is provided for stopping at two angular positions, and the housing has a bag portion at the end of the opening that engages with the rising portion at the tip of the movable plate, and a bag portion that engages with the rising portion at the tip of the movable plate, and This is achieved by a door structure of a casing that is provided with a stopper that abuts the movable plate below.

[Effect]

The door structure of the above-mentioned case is such that the single-swing door is shorter than the length of the opening, a movable plate is provided on the free end side of the door that can be stopped at only two positions by a torque spring, and the movable plate is rotated around the case. By providing a stopper that serves as a fulcrum when moving, the main door can be easily opened by pressing and rotating the tip of the movable plate, and it does not require a handle as in the conventional case, which is preferable in terms of appearance. .

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a diagram for explaining an embodiment of the present invention, in which a shows an overall perspective view, b shows a top view, and c shows an enlarged sectional view taken along the line C--C in FIG.

In this embodiment, as shown in FIG. 1a, a single-opening main door 11 having a length shorter than the length of the opening is provided in a housing 10 that is open on one side, and the end of the opening is provided on the free end side of the main door 11. A movable plate 12 is provided that reaches up to . As shown in FIG.
main door 1 so that it can only rotate inward of the housing.
It is attached to 1. In addition, the main door 11 and the movable plate 1
A toggle spring 15 is provided between the two.
Furthermore, as shown in FIGS. 1b and 1c, the housing 10 has a bag portion 16 with which the rising portion 13 of the movable plate 12 engages.
and a stopper (roller) 1 that comes into contact with the movable plate 12.
7 is provided.

In this embodiment configured as described above, when the tip of the movable plate 12 is pressed in the direction of the arrow P from the state where the door is closed as shown in FIG.
It rotates around 7 as a fulcrum and becomes in the state shown in Figure 2.
The engagement between the bag portion 16 of the housing and the rising portion 13 of the movable plate is released. The dimension l from the rising part 13 of the movable plate to the hinge of the main door is shortened to l', and even when the main door 11 is rotated in the direction of arrow Q, the bag part 16 and the rising part 13 do not interfere. Therefore, it is possible to easily open the main door 11 by placing a hand on the R portion. When closing the main door 11, the reverse operation is performed, and the rising portion 13 of the movable plate engages with the bag portion 16 of the casing, resulting in a locked state.

[Effect of idea]

As explained above, according to the present invention, the door can be opened and closed without the need for a handle, which is good in terms of appearance, and can be locked without the need for a magnetic catch. It has the effect of being able to join smoothly.

[Brief explanation of the drawing]

FIG. 1 is a diagram for explaining the door structure of a housing of the present invention, FIG. 2 is a diagram for explaining its operation, and FIG. 3 is a diagram showing a conventional housing for electronic equipment. In the figure, 10 is the housing, 11 is the main door, 12 is the movable plate, 13 is the rising part of the tip of the movable plate, 14 is the hinge,
15 is a toggle spring, 16 is a bag portion, and 17 is a stopper.

Claims (1)

[Scope of utility model registration request] In a case that is open at the front and has a single door in the opening, the door has a main door shorter than the length of the opening;
It consists of a movable plate provided on the free end side of the main door, the movable plate has a bent rising part at the tip, and is attached to be rotatable only inward of the casing by a hinge, Further, a toggle spring is provided between the movable plate and the main door to stop the main door and the movable plate at two positions, either in a straight line or at a certain angle, and the opening of the toggle spring is provided in the housing. A door structure for a housing, characterized in that a bag portion that engages with a rising portion at the tip of the movable plate is provided at an end of the movable plate, and a stopper that abuts the movable plate above or below the opening.
