Description

[Detailed description of the invention] One industrial field of application - This invention provides a support structure for a door provided in a case of an office machine,
In particular, the present invention relates to a support structure suitable for a door with a relatively small area provided on a console panel of office electronic equipment.

BACKGROUND OF THE INVENTION A console panel of an office machine is usually provided with various switches and keys for operating the console, but some of these switches are rarely operated. Therefore, by placing this seldom-operated switch in a recess in the housing and covering the recess with a door that is flush with the panel surface, the panel surface is avoided from being cluttered and the appearance is improved. A structure is adopted that improves the performance and avoids erroneous operation.

Due to its appearance, the door provided on such a console panel is closed flush with the panel surface when closed, and there is no gap or step between it and the main body, and it is simple in structure and easy to manufacture. Easy assembly is required.

Conventionally, as a support structure for such a door, the structure shown in Fig. 10 or Fig.
The structure shown in Figure 1 was used.

In the figure, 1 is the housing body, 11 is the main body panel, 12 is the panel surface, 3 is a recess provided in the main body, 4 is a switch provided in the recess 3 part, 2 is a door plate that covers the recess 3, 22 is a panel surface of the door plate, and 5 is a pin that pivots the door plate.

The one shown in Figure 0 is one in which the door plate 2 is simply pivoted by a pin 5 provided inside the panel surface 22.
1, the tip of an arm 51 extending from the base end of the door plate 2 is pivotally supported by a pin 5 provided inside the panel surface 12 of the main body at a position slightly apart from the door plate 2. here pin 5
The reason why both are provided inside the panel surface 22.12 is to prevent the pivot portion of the door plate 2 from protruding above the panel surface 22.12 and spoiling the appearance of the device.

-Problems to be Solved by the Invention- However, with the structure shown in FIG. It is essential to provide a slight gap C between 23 and 13, which has the drawback of impairing the appearance of the device. In addition, in the case of the one shown in FIG. 11, in order to prevent a gap from forming between the door plate 2 and the main body 1, it is necessary to increase the dimensional accuracy of @51 and the positional accuracy of the pin 5, which increases manufacturing costs. There are some drawbacks. Furthermore, in the above structure, especially the structure shown in FIG. 11, it is necessary to form the pin 5 in the recess 3, so whether the pin is integrally molded with the main body 1 or implanted separately, 1. There was a problem that manufacturing was complicated.

In this invention, the members constituting the pivot mechanism of the door plate 2 are attached to the main body.
It can be easily integrally molded with synthetic resin together with the door plate 2, and there is no gap between the door plate and the main body when the door is closed. The purpose of the present invention is to obtain a structure that does not create any recesses or recesses and allows the door plate to be opened and closed smoothly.

Means for Solving a Problem - The door plate support structure of the present invention is capable of supporting the door plate 2 by engaging a member integrally formed with the door plate 2 and a member integrally formed with the main body 1. A pivot mechanism is formed.

According to the configuration of the present invention, the arm member 25 is integrally formed on the door plate 2 and extends from the back surface of the base edge 23 side thereof. This arm member 25 extends beyond the base edge 23 to the panel surface 2 of the door plate.
2, an arcuate edge 29 is formed on the base end side of the inner edge 28, and a retaining protrusion 27 is provided at the tip.

On the other hand, on the bottom plate 31 of the recess 3 formed in the housing body 1, adjacent to the side edge 8!13 that abuts the base edge 23 of the door plate,
An opening 34 formed in the door plate 2 through which the arm member 25 is inserted.
A rib 15 is formed adjacent to the opening and extends from the back surface of the bottom plate 31 to the back surface of the main body panel 11 adjacent thereto.
7 and an arcuate edge 19 on the side that connects with the main body panel.

At least the portions of the arcuate edges 19.29 of the ribs and arm members connected to the main body panel 11 or the door plate 2 have their center P (PI, P2) at the proximal end of the door plate when the door plate 2 is closed. It is an arc located outward from the edge 23 on the main body panel side.

Generally and strictly speaking, the position that the center P (PI and P2) of the above circular arc should take is as shown in Figure 2.
1. P2 is the boundary line determined by the condition that the abutment surface a between the base edge of the door plate and the edge of the recess does not interfere when the door is opened and closed, and the back surface of the door plate is the bottom surface of the recess (Fig. In the case of , the boundary line l is determined based on the condition that it does not interfere with the protrusion 32), and the fitting surface between the leading edge of the door plate and the edge of the recess opposing this is determined based on the condition that it does not interfere when the door is opened and closed. This means that it is located in a region R surrounded by a boundary line m and a boundary line n determined based on the condition that the arcuate edge 19 can be substantially formed. Here, the boundary line is a line drawn from the outer edge S of the abutting surface a perpendicular to the abutting surface, and the boundary line 1 is a line drawn from the inner end t of the abutting surface a at right angles to the panel surface. m is the inner end U of the mating surface
The boundary line n, which is a line drawn perpendicularly to the surface of the cough fitting base, is a line drawn inclined toward the recess 3 side from the contact point V between the tip of the arm member and the back surface of the main body panel.

Strictly speaking, the above is as described above, but although there is a slight clearance necessary for opening and closing between the door side and the main body side, the center P is slightly beyond l, m, and n to the boundary line. There is no problem in practice even if the center P1 of the arcuate edge 19 and the center P2 of the arcuate edge 29 are not evenly matched. Furthermore, the main body panel 11 or the door plate 2 with the arcuate edge 19.29
The part beyond the vicinity of the connecting part with the main body 1 can be configured to have a lower shape than the above-mentioned shape so that an appropriate clearance is created between the door plate 2 and the main body 1 when the door is opened.

-Function- The arm member 25 of the door plate is integrally molded with the door plate 2, and the opening 34 and rib 15 provided in the bottom plate 31 of the recess are also formed in the case body 1.
It is integrally molded with. Then, the door plate 2 is inserted into the opening 34 by inserting its arm member 25 into the stepped portion 2 of the engagement protrusion 27 at the tip.
6 is attached to the housing body 1 by engaging the inner edge 18 of the rib 1'5 of the body.

In this installed state, the door plate 2 is attached to the arcuate edge 29 of the arm member.
slides along the tip W of the opening 34, and the step 2 of the locking protrusion
6 slides along the arcuate edge 19 of the rib 15, opening and closing becomes possible as if both were pivotally supported by a bottle.

When the door plate 2 is closed, the door plate 2 is closed due to the interaction between the arcuate edge 19 or 29 that is generated when the door plate 2 is rotated in the closing direction and the stepped portion 26 or the tip W of the opening that is in sliding contact with the arcuate edge 19 or 29. A force is generated that moves the proximal edge 23 of the plate in the direction of the edge 13 of the recess, so that the door plate 2 is closed with the proximal edge 23 and the edge 13 in close contact.

Furthermore, when the door plate 2 is opened and closed, the base edge 23 of the door plate rotates while being displaced in the direction away from the edge 13 of the recess, and the outer area 23a of the base edge gets under the outer area 13a of the edge. The opening/closing operation is not hindered by the opening/closing operation, and the door plate 2 can be opened/closed smoothly.
