DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device housing installed on an indoor wall, for example.

[0002]

2. Description of the Related Art A system for centrally monitoring security monitoring information and the like of a business establishment such as a financial institution using a telephone line is known. FIG. 4 is an external view of an example of a housing 1 of an electronic device used as a terminal device of this type of system.

The electronic device housing 1 is mounted on a wall 2 of an indoor room of a business office in a so-called wall-hanging manner as shown in the figure. This electronic device housing 1 has a substantially rectangular parallelepiped outer shape, for example, width × height × depth = 32 cm
It has a size of about × 46 cm × 7 cm.

The electronic device housing 1 is composed of a base 3 and a cover 4 made of, for example, a synthetic resin.

As shown in FIGS. 5A and 5C, the base 3 is formed in a box shape having a U-shaped cross section and an opening 3a on one side. Although not shown, a circuit device of an electronic apparatus is accommodated in the base 3. FIG. 5A is a top view when the base 3 is viewed from the opening 3a side, and FIG.
Is a partial sectional view of the side surface.

As shown in FIG. 5B and FIG. 5D, which is a partial cross-sectional view of a side surface thereof, the cover 4 is formed in a thin box shape having a U-shaped cross section like the base 3 and an opening 4a on one side. And a cover surface 4b for closing the opening 3a of the base 3. FIG. 5B and FIG.
Is shown in a state in which is opened 90 degrees with respect to the base 3.

By the way, the electronic device as a terminal device of this type of system needs to inspect the inside of its housing for maintenance and the like as appropriate. Installed. And, in order to facilitate the maintenance work of the worker,
The structure is such that the cover 4 does not close naturally.

In the case of the example shown in FIG. 4, the cover 4 can be rotated in the right direction in the width direction in the horizontal direction with the direction along the vertical direction when attached to the wall 2 as the direction of the rotation axis Rz. As described above, it is attached to the base 3.

That is, as shown in FIGS. 5A and 5C, the right and left ends of the base 3 in the width direction are erected from the bottom surface 3b along the wall when the base 3 is attached to the wall. Rotation supporting plates 6u and 6d are provided.
5A, the rotation support plates 6u and 6d have surfaces orthogonal to the direction of the rotation axis Rz of the cover 4 shown by a dashed line in FIG. Pins 7u and 7d are provided. That is, the line connecting the centers of the pins 7u and 7d is the rotation axis Rz.
Becomes

On the other hand, at the corresponding upper and lower right and left ends of the cover 4 in the width direction, there are provided recessed holes 8 for fitting the pins 7u and 7d.
u and 8d are formed. Since the rotation support plates 6u and 6d can elastically bend in the direction of the rotation axis Rz, the pins 7u and 7d are fitted into the recesses 8u and 8d of the cover 4 to cover the rotation. 4 can be attached to the base 3 so as to be rotatable about a rotation axis Rz.

In this conventional example, the cover 4
When the cover 4 is rotated by 90 degrees or more with respect to the base 3 on the surface provided with the concave holes 8u and 8d,
Lock bosses 9u and 9d, which are formed by, for example, mountain-shaped protrusions, are provided to prevent the cover 4 from easily closing from the 90-degree rotation position toward the base 3.

The pivoting operation of the cover 4 of the prior art will be described with reference to FIGS. 6A, 6B and 6C.

That is, FIG. 6A shows a state of the rotating portion when the cover 4 is closed with respect to the base 3 and the opening 3a of the base is closed. At this time, as shown in the figure, the lock bosses 9u and 9d do not collide with the rotation support plates 6u and 6d. At this time, the cover 4 is locked with respect to the base 3 by the key K shown in FIG.

In this state, the key K is unlocked and the cover 4
Is rotated about the rotation axis Rz, the lock boss 9u
And 9d abut against the rotation support plates 6u and 6d. However, when the operator continues to forcibly rotate, as shown in FIG. 6B, the lock bosses 9u and 9d
Move the rotation supporting plates 6u and 6d to the pins 7u and 7d.
Then, the cover 4 is rotated while being depressed and biased to such an extent that the engagement between the recesses 8u and 8d is not released.

Then, when the cover 4 is rotated by 90 degrees or more to reach the state shown in FIG. 6C, the lock boss 9u
And 9d are released from the state of pressing and biasing the rotation support plates 6u and 6d, so that the rotation support plates 6u and 6d elastically return to their original positions. Therefore, when the cover 4 attempts to rotate in the closing direction, the lock bosses 9u and 9d abut against the rotation supporting plates 6u and 6d, and unless the cover 4 is forcibly rotated in the closing direction by a predetermined force. Maintain an open state with respect to the base 3 for 90 degrees or more.

[0016]

The conventional electronic device housing has the above-described structure, and therefore, has a cover 4.
In the closed state, the key K is applied.
The weight of the cover 4 is supported by the portion, the rotation support plate 6 u on the upper side of the base 3, and the other engaging portion of the base 3 with the cover 4, as shown in FIGS. 6B and 6C.
When the cover 4 is opened by rotating the cover 4, the cover 4 in the direction of gravity is
Is supported, and the weight of the cover 4 is entirely applied to the rotation support plate 6u on the upper side of the base 3.

For this reason, there is a problem that the cover 4 hangs down in the direction of gravity and the appearance is poor. For this reason, when the size of the housing of the electronic device is increased, a reinforcing bracket is required for the rotation support plate 6u on the upper side of the base 3.

The lock bosses 9u and 9d are used as means for preventing the cover 4 from rotating in the closing direction from the open state of the cover 4 at 90 degrees or more, but this is not complete. Was.

Furthermore, in the conventional electronic device housing 1, when the cover surface 4b of the resin cover 4 is pressed in the direction of the wall 2 to which the housing 1 is attached, a so-called squeezing state is obtained, and the strength of the housing is increased. Had a feeling that there was a problem in terms of

According to the present invention, in view of the above points, the cover does not hang down without using the reinforcing metal,
In addition, an object of the present invention is to provide an electronic device housing capable of sufficiently suppressing the rotation of the cover 4 in the closing direction from the 90-degree open state of the cover and also capable of reinforcing the cover.

[0021]

In order to solve the above-mentioned problems, an electronic apparatus housing according to the present invention is described below with reference to FIGS.
When the base 3 is attached to a wall surface, the opening 3a is provided on one surface side and a space for accommodating an electronic device is provided in the opening 3a.
And a cover surface 4b for closing the opening 3a of the base 3.
At the upper and lower ends when attached to the wall of the base 3, the base 3 is rotatably attached to the base 3 with a direction along the vertical direction as a rotation axis Rz direction. An electronic device housing including a cover 4 which is turned to a state where the opening is closed and a state where the inside of the base 3 is exposed to the outside, wherein the cover 4 is located near the position of the rotation axis Rz of the cover 4. In the middle part in the up-down direction, a convex portion 10 provided so as to project toward the base 3 in a direction substantially perpendicular to the cover surface 4b, and corresponding to the convex portion 10 And an abutment member 20 provided on the base 3.
A first edge 12 connected to the cover surface 4b, a second edge 13 at a position separated from the cover surface 4b, and an arc-shaped edge 14 connecting the first and second edges. The distance from the rotation axis Rz position of the cover 4 to the second edge 13 is a predetermined distance d1, and the distance from the rotation axis Rz position of the cover 4 to the arc edge 14 is The distance d2 is set to be larger than the distance d1, and the abutment member 20 is parallel to the first support portion 22d that supports the convex portion 10 from below in the up-down direction and the wall surface of the base 3. A surface 2 which is planted from the surface 3b and which is separated from the rotational axis Rz position of the cover 4 by the distance d1.
1a, an abutment plate 21 that can be elastically displaced, and a second support portion 23 that has a surface 23a in a direction along the wall surface at a position separated by the distance d1 from the rotation axis Rz position of the cover 4. It is characterized by having.

[0022]

According to the present invention having the above-described structure, the first supporting portion on the base side supports the convex portion provided on the cover side from below, thereby preventing the cover from hanging down in the direction of gravity. .

Further, when the cover is rotated in the opening direction about the rotation axis, the first edge of the convex portion of the cover is continuously applied to the abutting plate constituting the abutting member of the base. Since the arc-shaped edge abuts and the distance d2 between the arc-shaped edge and the rotation axis position is larger than the distance d1 between the abutment plate and the rotation axis position, the arc-shaped edge of the convex portion is: The abutment plate is elastically biased. The operator can rotate the cover in the opening direction against the pressing bias force.

Then, when the cover is rotated by about 90 degrees, the abutment plate is in a state of facing the second edge of the convex portion. Since the distance d1 between the second edge and the rotation axis position is equal to the distance d1 between the abutment plate and the rotation axis position, the abutment plate and the second edge of the convex portion are inelastic. The cover comes into contact with or comes into contact with the base, and stops rotating when the cover is opened at 90 degrees with respect to the base.

As long as the cover does not receive a force in the direction in which the arc-shaped edge of the convex portion closes against the force of elastically pressing and biasing the abutment plate, the cover is kept in this 9
Maintain the 0 degree open state.

When the operator rotates the cover in a direction in which the arc-shaped edge of the convex portion closes against the force of elastically pressing and biasing the abutment plate, the cover covers the opening of the base. So closed.

When the cover is closed and a force is applied in the direction of the cover surface, the second edge of the convex portion of the cover abuts the second support portion of the base, and the second edge of the convex portion of the cover abuts. The cover surface is blocked. For this reason, even if it pushes a cover surface, it does not squeak.

The configuration in which the fitting recesses 8u and 8d of 7d and 7d are provided is the same as in the example of FIG.

In this embodiment, a convex portion 10 is provided near the position of the rotation axis Rz and in the middle of the cover 4 in the direction of the rotation axis Rz. Is provided with an abutment member 20.

The structures of the projection 10 and the abutment member 20 will be described below with reference to FIGS. 2A and 2B, which are partial cross-sectional views taken along the line XX of FIGS. 1A and 1B.

First, the convex portion 10 provided on the cover 4 will be described.

In this embodiment, the convex portions 10
Is a predetermined thickness t, _(in the example of FIG, n = 4) a plurality of plate-shaped convex member 11 ₁ to 11 n having the same shape made of.
Each of the plurality of plate-like convex bodies 11 _{1 to} 11 _n is:
It is planted from an L-shaped section having a cover surface 4b and a side surface 4c perpendicular to the cover surface 4b, and is perpendicular to the cover surface 4b and the side surface 4c.

[0035] Then, as shown in Figure 2B, each of the plurality of plate-shaped convex member 11 ₁ to 11 _n, contiguous to the cover surface 4b, a first end edge 1 straight perpendicular to the cover surface 4b
2, a linear second edge 13 at a position separated from the cover surface 4b and parallel to the cover surface 4b;
Arc-shaped edge 1 connecting between the edge 12 and the second edge 13
4 is provided.

The distance from the rotation axis Rz position of the cover 4 to the first edge 12 and the distance to the second edge 13 are equal, and are selected as the distance d1. The distance from the rotation axis Rz position of the cover 4 to the third edge 14 is selected to be a distance d2 (> d1) larger than the distance d1.

On the other hand, as shown in FIGS. 1A and 2A,
The abutment member 20 includes an abutment plate 21, two support plates 22 u and 22 d provided on the abutment plate 21, and a support base 23.

When the base 3 is mounted on the wall surface, the abutment plate 21 is erected from the bottom surface 3b of the base 3 which is parallel to the wall surface, and is parallel to the rotation axis Rz direction of the cover 4, and A surface 21a is provided at a position separated from the axis position by the distance d1.

The position where the abutment plate 21 is planted from the bottom surface 3b of the base 3 is a position corresponding to the position of the convex portion 10 of the cover 4. The rotation axis Rz of the surface 21a
The width W2 in the direction is the width W of the convex portion 10 in the rotation axis Rz direction.
The abutment plate 21 is provided at a position wider than 1 and in a state where the width W1 is included in the width W2. In this case, particularly, the surface 21 a is
It is configured to project below the position of 0 in the direction of the rotation axis Rz.

As shown in FIGS. 1A and 2A, two support plates 22 and 22d are provided on the surface 21a of the abutment plate 21.
The abutment plate 21 is provided so as to protrude from the vicinity of both ends in the direction of the rotation axis Rz to the projection 10 of the cover 4 in a state orthogonal to the abutment plate 21.

In the case of this embodiment, the two supporting plates 22u and 22d sandwich the convex portion 10 of the cover 4 from both the upper and lower sides in the direction of the rotation axis Rz. The support plates 22 are provided. In particular, the upper surface of the lower support plate 22d is configured to be in contact with the lower surface of the lowermost plate-shaped convex body 11n in the rotation axis Rz direction of the convex portion 10. This is because the convex portion 10 is supported from below by the support plate 22d, as described later.

The support base 23 has a plate surface 23a projecting from the side surface 3c along the rotation axis Rz of the base 3 in a direction perpendicular to the side surface 3c, and a bottom surface 3a from the plate surface 23a.
b, and a plate 23b extending to the plate 23b.
There is no elastic bias due to the presence of b. And
The plate surface 23a of the support base 23 is provided at a position separated from the rotation axis Rz by a distance equal to the distance d1 or a distance slightly longer than the distance d1. In addition, the surface of the plate surface 23a may be formed to have a slight curvature so that a space for rotating the convex portion 10 can be secured when the cover 4 rotates.

With the above configuration, when the cover 4 is closed and the opening 3a of the base 3 is closed, the relationship between the convex portion 10 and the abutment member 20 is as shown in FIG.
The state is as shown in the figure. That is, in this state, the second edge 13 of the convex plate-like bodies 11 _{1 to} 11 _n of the convex portions 10 is formed.
And the plate surface 23a of the support base 23 of the abutment member 20 is in contact with or in contact with a slight gap.

For this reason, in FIG.
Even if a force in the direction perpendicular to the cover surface 4b as shown by 1 is applied, the convex portion 10 is supported by the support stand 23, and the cover surface 4b does not limp.

Further, as shown in FIG.
0 convex plate-like body 11 ₁ to 11 first end edge 12 of _n of, since it is brought into contact with the abutment plate 21 of the abutment member 20, the central portion of the side surface along the rotation axis Rz of the cover 4 But arrow 32
Is supported by the abutment plate 21 against the force from the direction of, so that the side surface of the cover 4 along the rotation axis Rz can be prevented from warping.

When the electronic device housing of this embodiment is mounted on a wall surface, the upper surface of the support plate 22 d below the abutment member 20 of the base 3 is rotated by the projections 10 of the cover 4. It comes into contact with the lower surface of the lowermost plate-shaped convex body 11n in the direction of the dynamic axis Rz, and the support plate 22d always supports the convex portion 10 from below. Therefore, even when the cover 4 is open, the cover 4 is supported not only by the upper rotation support plate 6u but also by the support plate 22d, thereby preventing the cover 4 from hanging down. For this reason, even when the size of the electronic device housing is increased, the weight of the cover 4 can be sufficiently supported without using any reinforcing metal.

Next, when the cover 4 is rotated in a direction to open from the base 3, the relationship between the convex portion 10 and the abutment member 20 is as shown in FIG. 3B. That is, in this state, the arc-shaped edges 14 of the convex plate-like bodies 11 _{1 to} 11 _n of the convex portions 10 bias the abutment plate 21 of the abutment member 20 in the direction of the arrow 33 as illustrated. State.

In this embodiment, the cover 4
Of the protruding plate-like bodies 11 _{1 to} 11 _n of the protruding portions 10 of the abutment plate 2
1 from the first edge 12 to the arcuate edge 14
In the section up to the center portion, the biasing force of the abutment plate 21 acts in the direction of closing the cover 4, and the operator forcibly turns in the direction of the arrow 34 with the force opposing the biasing force of the abutment plate 21. By moving, the cover 4 can be opened.

Then, by forcible rotation of the operator,
If abutment portion between the convex plate-like body 11 ₁ to 11 _n of the abutment plate 21 of the convex portion 10 of the cover 4 is composed of arc-shaped end edge 14 in the section that moves the second edge 13, Opposition Since the biasing force of the plywood 21 acts in a direction to open the cover 4, the rotation of the cover 4 becomes light.

The cover 4 of the abutment plate 21 at this time is
3C, the surface 21a of the abutment plate 21 is brought into contact with the second edge 13 of the protruding plate-like bodies 11 _{1 to} 11 _n by the biasing force in the direction in which the cover 4 is opened. The rotation stops.

Next, when the cover 4 is rotated from the open state in FIG. 3C in the direction in which the cover 4 is closed, the protrusions 11 _{1 to} 11 _n of the protrusions 10 of the cover 4 come into contact with the abutment plate 21. In the section where the joining portion extends from the second edge 13 to the center of the arc-shaped edge 14, the biasing force of the abutment plate 21 acts in a direction to open the cover 4, so that the cover 4 is pressed against the cover 4 by a force opposing this. The cover 4 cannot be closed unless it is forcibly rotated.

Therefore, according to the electronic device housing of the above-described embodiment, the cover 4 is reliably held in a state of being opened 90 degrees with respect to the base 3 by the convex portion 10 and the abutment member 20. be able to.

In the above embodiment, the protruding portion 10 and the abutment portion 20 are provided only at one position substantially at the center of the base 3 and the cover 4 in the direction of the rotation axis Rz. By providing the cover 4 at a place, it is possible to enhance the effect of preventing the cover 4 from sagging, the effect of reinforcing against the pressing force from the cover surface direction, and the effect of preventing the side surface of the cover 4 from warping.

Further, although the convex portion 10 is constituted by a plurality of plate-like members, it may be constituted by a single thick plate-like member.

[0055]

As described above, according to the present invention, it is possible to prevent the cover from hanging down.
It does not detract from aesthetics.

Further, the cover can be reliably held in a state of being opened at an angle of 90 degrees or more with respect to the base.

Further, with the cover closed on the base,
In the vicinity of the rotation axis position, even if the cover surface is pressed from a direction perpendicular to the cover surface, the cover hardly shifts. Therefore, even if the cover is made of resin, for example, it is possible to prevent a problem in strength. . This is also advantageous when the cover is made of a thin plate to reduce the weight.
