Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a novel casing for electronic equipment. Specifically, it relates to an electronic device housing in which a lid for opening and closing an opening formed in the housing body is rotatably connected to the housing body, and special connecting parts such as so-called hinges are used. The lid can be rotatably connected to the casing body without any problems, and the locked state in which the opening of the lid body is locked in the closed position can be released with approximately one movement. A new electronic device that allows the rotating end of the lid to be automatically displaced in the opening direction by the restoring force of the bent lid when the lid is released from the locked state without using an elastic member. The purpose is to provide a housing for equipment.

BACKGROUND ART For example, there are various types of electronic device casings that open and close an opening formed in a certain casing body, such as an electronic device casing that opens and closes the opening of a battery storage recess provided in an electronic device. There are several types, but they can be broadly classified into sliding types and rotating types based on the operation of opening and closing the opening of the lid body.

FIG. 8 shows an example of a conventional sliding type electronic device housing.

For example, a is the outer casing of a tape recorder.
b is a battery storage recess provided in the outer casing a, and the battery storage recess b has an opening e continuous to the bottom plate c of the outer casing a and the side plate 1d. f, f are openings e
These are step portions formed on both side edges in the width direction, and the lid body is supported by the step portions f, f. g, g
are engagement protrusions formed so as to project inward from a continuous portion of the opening e on the bottom plate c side and the side plate d side. In addition, h is the end surface of the inner surface of the bottom plate c on the side of the plate d opposite to the opening e.
This is an engagement recess formed in a portion spaced slightly inward from _e1 .

i is a lid for opening and closing the opening e. j is an engaging claw protruding from the inner surface of one end in the longitudinal direction of the lid i, and k and k are engagement claws protruding from the inner surface of the other end in the longitudinal direction of the lid i. It is a protrusion.

Then, the lid i is moved in the direction indicated by the dashed-dotted line arrow with both ends in the width direction abutting against the steps f, f formed on both side edges of the opening e of the battery loading recess b. When it is slid, the engaging pawl j formed at one end of the lid i has a slope j ₁ formed at its tip that abuts the lower edge of the end surface e ₁ of the opening e and moves relatively downward. As it is pressed, it moves to the inside of the bottom plate c, and the engagement surface _j2 formed on the inside engages with the end face on the opening e side of the engagement recess h formed in the bottom plate c. will be combined. At the same time, the engaging protrusions k, k formed on the other end of the lid i come to be engaged with the inner surfaces of the engaging protrusions g, g formed in the opening e.
As a result, the lid i is attached to the outer casing a with the lid i locked in the position where the opening e is closed.

In addition, in order to remove the lid i attached to the opening e of the outer casing a in this way, press one end of the lid i (the side where the engaging claw j is formed) from the outer surface side. The engagement between the engagement surface _j2 of the engagement claw j and the engagement recess h is released, and in this state, the lid body i is slid toward the side opposite to the engagement recess h. As a result, the engaging protrusions k, k on the side of the lid i
Since the engaging protrusions g and g on the opening e side are disengaged, the lid i can be removed from the outer casing a.

Problems to be Solved by the Invention The above-mentioned sliding electronic device casing consists of only the lid and the casing to which it is detachably attached.
The structure is extremely simple and does not require any assembly work, so it has the advantage of being low in cost. However, on the other hand, when the opening e is opened, the lid i is removed from the outer casing a. There is a problem that it is easy to lose it or break it somehow. Moreover, in order to attach the lid i to the opening e, the lid i is first placed on the steps f, f, and then the lid is slid. However, since the stepped portions f and f of the opening e are normally formed to be extremely narrow, the lid i
It is more difficult than expected to place the
Further, when sliding the lid, if a biased force is applied to the lid i, one end of the lid i may lift up, making it troublesome to handle.

On the other hand, in a rotary electronic device housing, the lid is generally connected to the housing, so when the opening is opened, the lid will not be removed from the housing.
There is no chance of losing the lid, and there is little risk of it being damaged. And the operation on the lid body,
Since the lid body itself is rotatably connected to the housing side, this can be done extremely easily.

However, this rotatable housing for electronic devices requires a rotatable connecting part such as a hinge or ribbon to connect the lid to the housing, and furthermore,
Since it is necessary to provide a handle member for operation such as a knob or button, a knob for unlocking, etc. on the lid body, there is a problem that the structure becomes complicated. Such a structure naturally requires work to assemble the electronic device casing, which ultimately increases the cost of the device.

In addition, in rotary electronic device casings, a so-called pop-up means is sometimes provided so that the lid automatically lifts up to a certain extent when the lid is unlocked. Functional electronic device casings are usually provided with resilient members such as leaf springs, which increases the number of parts and the number of assembly steps.

Means for Solving the Problems Therefore, in order to solve the above-mentioned problems, the electronic device casing of the present invention is an electronic device casing having a casing body and a lid body. has a storage recess and its opening, an engagement recess is formed on the inner surface of the housing wall plate connected to the opening, and a support portion is formed on the inner surface facing the housing wall plate across the opening. The lid is flexible in the thickness direction, covers the opening, and is slidably and rotatably attached to the housing body, with the engaging claw located at the center of the tip side. The rotating support portion is formed on both sides of the lid, and the housing body and the lid are connected so that the rotation support portion of the lid body slides relative to the support portion of the housing body. is slidably and rotatably fitted while being regulated, and the engaging pawl is engaged in the engaging recess, and the distal end side of the lid body is pressed from above,
When the lid body is bent and slid in the detachment direction to disengage the engagement claw and the engagement recess, the top surface of the engagement claw comes into contact with the end face of the opening of the housing body, and the lid body The other end of the lid body is rotated so as to be lifted by the restoring force of the lid body.

Effects Therefore, according to the present invention, an electronic device casing can be constructed from only the minimum necessary parts, such as a lid and a casing body that supports the lid, and the lid is attached to the casing body. There is no risk of losing it as it is connected to the In addition, the lid can be unlocked by approximately one action, such as pressing one end of the lid from the outside and sliding it to a certain extent, and the bent lid can be moved to the same position. Since the pivoting end of the lid body is automatically displaced in the opening direction by the restoring force that tends to return to the original position, the operability becomes extremely easy.

Reference numeral 21 denotes a lid for opening and closing the opening 5. The lid body 21 is formed of synthetic resin so as to have some degree of flexibility in the thickness direction, and has a bottom surface portion 2 that closes a portion 5a of the opening portion 5 on the bottom plate 6 side.
1a and the side surface portion 21b that closes the portion 5b of the opening 5 on the left side plate 7 side are integrally formed.
It is formed to have a substantially L-shape when viewed from the front and rear directions.

Reference numeral 22 denotes an engaging pawl formed to protrude from approximately the center in the longitudinal direction of the distal end surface 23 of the bottom surface portion 21a of the lid body 21 toward the opposite side surface portion 21b. The engaging pawl 22 is positioned so as to face a relatively thin connecting portion 22a that connects with a portion of the tip surface 23 of the bottom plate portion 21a of the pocket lid 21 that is closer to the inner edge, and the tip surface 23 of the bottom plate portion 21a. The claw part 22b has an engaging surface 24 which has a flat surface, and an engaging guide surface 25 that extends diagonally away from the outer surface of the bottom plate part 21a as one goes from the upper edge of the engaging surface 24 toward the tip.

26 and 26' are formed to protrude outward from the tips of both side surfaces in the width direction of the bottom surface 21a of the lid 21, that is, in a direction perpendicular to the L-shaped extending direction of the lid 21. The guide projections 26, 26' are formed into a substantially cylindrical shape that is short in the axial direction.

Further, 27 and 27' are side parts 21b of the lid body 21.
These are engagement protrusions formed along both sides of the inner surface in the width direction and at positions slightly spaced apart from a portion continuous with the bottom surface portion 21a.

Reference numeral 28 denotes a knurled anti-slip portion formed on a portion of the outer surface of the bottom surface portion 21a of the lid body 21 near the tip.

Note that the guide recess 1 formed in the opening 5

The relationship with the length l ₂ of the claw portion 22b is l ₁ +l ₂ >L. That is, the length L of the guide recesses 15, 15' is equal to the length L of the guide protrusions 26, 2.
The length is shorter than the sum of the diameter l ₁ of 6' and the length l ₂ of the claw portion 22b.

The lid 21 described above is connected to the outer casing 2 by slidably engaging the guide protrusions 26, 26' with the guide recesses 15, 15' formed in the opening 5.

Note that the guide protrusions 26, 2 formed on the lid body 21
6' with the guide recesses 15, 15' of the opening 5, for example, with one guide protrusion 26 engaged with one guide recess 15, the tip of the bottom surface 21a of the lid body 21 This can be done by bending the portion so that it is warped to some extent, and then engaging the other guide protrusion 26' with the other guide recess 15'.

Therefore, the lid body 21 has its guide protrusions 26, 2
6' is slidably and rotatably engaged with the guide recesses 15, 15' of the opening 5, so that it is slidably and rotatably supported with respect to the outer casing 2. It turns out.

The sliding stroke of the lid 21 is set within a range in which the guide protrusions 26, 26' can move within the guide recesses 15, 15'.

Thus, the lid body 21 has the claw portion 22b of the engaging claw 22 that projects out of the battery storage recess 4 in the outer casing 2 through the notch 20 formed in the partition plate 8.
By engaging the engagement surface 24 with the end surface 19a of the engagement recess 19 formed on the bottom plate 6 of the outer casing 2 on the opening 5 side, sliding toward the opposite engagement recess 19 side is prevented. At the same time, the engaging protrusions 27, 27' formed on the rotating end side are engaged with the engaging protrusions 17, 17' formed in the opening 5 from the upper surface side of the outer casing 2. Rotation is prevented. Thereby, the closed state of the opening 5 of the lid 21 is locked.

In addition, in this state, the guide protrusion 2 of the lid body 21
6, 26' are the engagement recesses 1 of the guide recesses 15, 15'.
It has come to a position where it almost touches the end face on the 9th side (the
(See Figure A).

Therefore, as described above, the lid 21 is locked.
The opening operation is performed as follows, for example (see FIG. 5).

First, as shown in FIGS. 5A and 5B, the lid 21
The center portion of the tip of the bottom surface portion 21a, that is, the engaging claw 2
Press the area where 2 is formed from the outer surface side with your fingertip. That is, the anti-slip portion 28 is pressed.

Then, as shown in FIG. 5B, the bottom surface portion 21a is bent so that the approximately central portion of its tip portion is bent toward the inside of the outer casing 2, so that the engaging claw 22 is bent toward the opposite bottom plate 6.
It is forced to move to the side. As a result, the engaging claw 2
Since the second claw portion 22b comes out of the engagement recess 19, the engagement between the engagement surface 24 and the engagement end surface 19a of the engagement recess 19 is released.

Then, from the state shown in FIG. 5B above, the lid body 21
When the is slid toward the anti-engagement recess 19 side, as shown in Fig. 5C.
As shown in FIG. 2, the engagement between the engagement protrusions 27 and 27' formed on the side surface 21b of the lid 21 and the engagement protrusions 17 and 17' formed on the opening 5 side is released. , the guide protrusions 26, 26'' of the lid 21 come into contact with the end surfaces of the guide recesses 15, 15' formed in the opening 5 on the anti-engagement recess 19 side. is prevented from sliding toward the anti-engagement recess 19 side.In this state, the claw portion 22b of the engagement claw 22 has a substantially central portion in the inclination direction of the engagement guide surface 25 on the right side of the opening 5. The guide recesses 15 and 15' formed in the opening 5 have a length L that is opposite to the inner edge of the end surface 9 in the vertical direction.
Length l 1 of the guide protrusions 26, 26' _{of 1} and the claw portion 22
Since the length of b is shorter than the sum of the length _l2 , the guide protrusions 26 and 26' are connected to the guide recesses 15 and 26'.
Even if it comes into contact with the end surface of the anti-engaging recess 19 side of 15',
The entire claw portion 22b does not come closer to the anti-engaging recess 19 than the right end surface 9 of the opening 5, but a portion thereof is positioned closer to the engaging recess 19 than the right end surface 9 described above.

Therefore, from the state shown in FIG. 5C, the lid body 21
When the finger that was pressing is released, the lid 21 is automatically rotated so that its rotational end, that is, the end on the side surface portion 21b side, is displaced in a direction away from the outer casing 2. That is, in the state shown in FIG. 5C, the center portion of the bottom surface portion 21a of the lid body 21 is bent by the pressing force from the outer surface;
When the pressing force is released from this state, the bent portion attempts to return to its original planar state. However, before the bent portion returns to its original flat state, the engagement guide surface 25 of the engagement claw 22 comes into contact with the inner surface of the cotton 9 at the right end of the opening 5, so that the original deflection is The restoring force that has been stored in the portion that had been pushed back to its original state is applied when the engaging claw 22 is in contact with the inner edge of the right end surface 9. Therefore, the restoring force of the lid body 21
, with the guide protrusions 26, 26' as the center of rotation, the end on the anti-engaging claw 22 side, that is, the side surface portion 21b.
This acts as a turning force that causes the side end to rotate so as to lift up.

Thus, the lid 21 is slid while the tip thereof is pressed, and by releasing the pressure, the rotating end is automatically displaced in the opening direction, that is, it is popped up. That will happen.

For example, when storing a battery in the battery storage recess 4, the popped-up lid 21 is
When the opening 5 is rotated as shown in FIG. 1, the opening 5 is opened wide, so that the batteries 29, 29 can be easily accommodated.

Then, in order to close the opening 5, the lid body 21 is
For example, operate as follows. That is, the lid body 21
from the state shown in FIG. 5E, the guide protrusion 2
6 and 26' are in contact with the end surfaces of the guide recesses 15 and 15' on the anti-engagement recess 19 side.
9 side, as shown in FIG. It is brought into contact with the engaging protrusions 17, 17'. In this state, the engagement claw 22 abuts the inner edge of the right end surface 9 of the opening 5 at the tip of the bottom surface portion 21a, so that the center portion thereof is bent so as to warp. As a result, a moving force is accumulated in the engaging claw 22 to move it toward the bottom plate 6 side. Therefore, the lid body 21 is slid toward the engagement recess 19 from the state shown in FIG. Then, when the engaging claw 22 passes the inner edge of the right end surface 9 of the opening 5, the engaging claw 22
2 is positioned in the engagement recess 19 by the moving force stored therein, whereby the engagement surface 24 of the claw portion 22b and the engagement end surface 19a of the engagement recess 19 are engaged. At the same time, the engaging protrusions 27, 27' on the lid 21 side and the engaging protrusions 17, 17' on the opening 5 side are engaged. As a result, the opening 5 of the lid 21 is locked in the closed state.

Modified Example FIG. 7 shows a modified example of the electronic device casing shown in the above embodiment.

The only difference between this modification and the embodiment described above is the position of the guide protrusion and guide recess, which are means for regulating the sliding stroke of the lid 21. Therefore, only the different parts will be described in detail, and the remaining parts will be designated by the same reference numerals as used in the previous embodiment, and their explanation will be omitted.

In the figure, 30, 30' are guides formed to protrude inwardly from the portions closer to the engagement recess 19 of both front and rear side surfaces 16, 16' of the portion 5a of the opening 5 on the bottom plate 6 side. It is a protrusion and has an approximately cylindrical shape that is short in the axial direction.

Further, 31, 31' are the bottom part 2 of the lid body 21A.
This is a guide recess formed at the wide end of both sides of 1a, and the guide recesses 31, 3
The length L of 1' is shorter than the sum of the diameters of the guide protrusions 30, 30' and the length of the claw 22b of the engagement claw 22.

Therefore, the lid body 21A has its guide recess 31,
A guide protrusion 30 formed in the opening 5 at 31',
30' is engaged, so that it is slidably and rotatably supported by the outer casing 2, and
The slide stroke is the guide recess 31, 3
The end face of 1' is brought into contact with the guide protrusions 30, 30' to form a certain range.
