DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening and closing mechanism for a lid attached to a small electronic device such as a portable cassette player or a disc player.
In particular, the present invention relates to a mechanism for opening and closing a lid of a battery provided to such electronic devices.

[0002]

2. Description of the Related Art As shown in FIG. 8, for example, a rechargeable battery is generally used as a power supply in a small-sized electronic device 50 such as a portable cassette player, a disc player, and an MD device. For this reason, the main body is provided with a cylindrical battery accommodating portion for loading a rechargeable battery, and is usually closed by a battery lid which is combined so as to constitute a part of the main surface of the main body.

[0003] The battery lid has conventionally employed various structures. Recently, as shown in FIG. 9, a rotary support rotatably supported by a fulcrum 52 provided at an opening of a battery accommodating portion. The main part is a battery lid 51 having a dynamic structure.

As shown in FIG. 10A, the battery cover 51 has a function as a terminal plate together with a cover function. For this reason, power supply in a state where the battery cover 51 is completely closed is a prerequisite, and it is particularly preferable that the portable device has a structure that does not easily fall off the main body. Therefore, as shown in FIG. 10B, when the battery cover 51 slides by a certain amount in the direction of arrow D, a claw 54 as a stopper mechanism provided at the end is provided.
And can be freely opened and closed by rotation as shown in FIG. 10 (c).

It is necessary that the battery cover 51 has a structure that can be easily opened and closed and the rechargeable battery 53 can be easily taken in and out. In addition, in a portable device, it is an essential condition that the device is small and robust as a whole, and the opening / closing mechanism of the battery cover 51 must also fulfill this condition.

[0006]

However, in the above-mentioned conventional opening / closing mechanism of the rotating type battery cover, the rotating fulcrum portion 52 is provided.
Must be provided outside the opening of the battery housing, and the battery cover 51 is considerably larger than the external dimensions of the rechargeable battery 53, which hinders miniaturization of the device. In addition, in order to reduce the thickness, which is the main focus of miniaturization, the installation position of the fulcrum portion 52 is not disposed outside the device at the opening of the battery storage section. Therefore, normally, the fulcrum 52 is set inside the device, and thus the internal space is restricted.

In the rotary type battery cover, a metal leaf spring of a rotary member is used as a locking mechanism for locking the claw of the cover convex portion into the hole of the main body concave portion by sliding movement as a stopper mechanism. Locks over the projection provided on the plastic battery lid body. However, plastic battery lid projections are not durable and can be easily opened while opening and closing a large number of battery lids.For example, the battery lid may open inside the bag while using the equipment. In each case, the power supply during use may be cut off.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object that the opening and closing operation is easy, the slide lock of the lid is not easily released, and the slide lock of the lid is released. It is an object of the present invention to provide a lid opening / closing mechanism that can prevent a stored object from falling off immediately, while achieving a reduction in size and thickness of a device main body.

[0009]

According to a first aspect of the present invention, there is provided a lid opening / closing mechanism for opening and closing a storage section for storing an object to be stored. In the opening / closing mechanism of the lid that is rotatably assembled after being slid, the lid is opposed to an opposing portion that stands upright in the storage direction of the storage object in the vicinity of the opening of the storage section. A facing member extending in the storage direction from an end of the portion and having a side plate pivotally supported on a side surface of the storage portion at a first fulcrum and rotated in parallel with the side surface of the storage portion, and a facing portion of the facing member. And a lid outer portion which is slidably supported by the facing portion on the outer side in the storage direction and is locked at its end to the device body.

[0010] According to the above invention, the lid is rotatably assembled after sliding with respect to the main body of the device in order to open and close the storage section in which the storage object is stored.

[0011] The lid body is provided with an opposing portion which is provided in the vicinity of the opening of the storage portion so as to face the storage direction of the object to be stored, and which extends from the end of the opposing portion in the storage direction to extend along the side surface of the storage portion. An opposing member having a side plate pivotally supported at a first fulcrum and rotated in parallel with the side surface of the storage portion, and slidably supported by the opposing member on the outer side of the opposing portion in the storage direction at the opposing portion. And a lid external part locked at its end to the device body.

[0012] That is, the facing portion is erected near the opening of the storage portion in the storage direction of the storage object.
The facing portion extends in the storage direction from the end of the facing portion, and is pivotally supported at a first fulcrum on the side surface of the storage portion. further,
The side plate is rotated parallel to the side surface of the storage unit.

Therefore, the direction in which the object is stored is different from the direction in which the facing portion is opened and closed. For this reason, even if an object to be stored tries to fly out, the facing portion only stands and blocks, and does not contribute to opening. For this reason, the lid is not easily opened.

The outer appearance of the lid is slidably supported on the opposite side on the outer side in the storage direction, and is locked to the main body of the device at its end. That is, it is slid locked. For this reason, the direction in which the object to be stored is stored is different from the direction in which the lid exterior portion is locked to the device body. Therefore, the locking of the external appearance of the lid body to the device main body is not easily released.

As a result, in both the facing member and the lid exterior part, the storage direction of the object to be stored, the opening / closing direction and the locking direction are different, and the lid does not open from the apparatus body.

In opening and closing, the outer appearance of the lid is slid to release the engagement with the main body of the device at the end, and then the entirety of the lid consisting of the outer appearance and the facing member is moved to the first fulcrum. It is only necessary to rotate around.

Therefore, the opening / closing mechanism of the lid can be easily opened and closed, the slide lock of the lid is not easily released, and even if the slide lock of the lid is released, the stored object can be prevented from falling off immediately. Can be provided.

According to a second aspect of the present invention, there is provided a lid opening / closing mechanism.
In order to solve the above problem, in the lid opening / closing mechanism according to claim 1, the first fulcrum formed on the side surface of the storage portion is located at a position within the thickness dimension of the storage object. Features.

In other words, the lid pivots around the first fulcrum and opens and closes. As the position of the first fulcrum moves outward from the thickness of the object, the first fulcrum and the first fulcrum move. The distance between the object and the opposing portion pressed by the object increases, the rotational moment increases, and the opposing portion easily rotates.
This means that the lid is easy to open.

However, according to the present invention, since the first fulcrum formed on the side surface of the storage portion is located at a position within the thickness dimension of the storage object, the rotational moment can be suppressed to a small value, and the lid can be formed. It can be prevented from being easily opened.

Further, if the first fulcrum, which is the center of rotation, is provided at a position outside the thickness of the object to be stored, the size of the apparatus body becomes large. Since it is provided at the position, the size of the device main body can be reduced.

As a result, the slide lock of the lid is not easily released, and even if the slide lock of the lid is released, it is possible to prevent the stored object from dropping off immediately.
It is possible to provide a lid opening / closing mechanism that can achieve a reduction in thickness.

According to a third aspect of the invention, there is provided an opening / closing mechanism for a lid,
In order to solve the above-mentioned problem, in the lid opening / closing mechanism according to claim 1 or 2, the opposing portion of the opposing member is provided with an urging means for pressing an object supported and stored by the opposing portion. Is provided.

In other words, if the object is pressing the facing portion of the facing member, the direction in which the object is housed is different from the direction in which the lid rotates, as described above. The lid does not open easily even if the slide lock of the body comes off, but if the facing part of the facing member does not come into contact with the object to be stored, in some cases, the lid may come off easily when the slide lock of the lid comes off. There is a possibility that the lid rotates and the lid opens.

However, in the present invention, the opposing portion of the opposing member is provided with an urging means which is supported by the opposing portion and presses the stored object. For this reason, the urging means constantly presses the object to be stored. As a result, even if the slide lock of the lid is released, the lid is not easily opened.

Further, since the urging means constantly presses the object to be stored, thereby providing resistance to the sliding of the lid outer portion, the slide lock of the lid can be prevented from easily coming off.

Since the urging means presses the object to be stored, when the lid is turned around the first fulcrum, it turns against the urging force of the urging means. This allows the lid to be easily opened, so that the urging means does not become a major obstacle to rotation.

As a result, the opening and closing operation is simple, and
It is possible to provide a lid opening / closing mechanism that makes it difficult for the slide lock of the lid to come off and prevents the stored object from immediately falling off even if the slide lock of the lid comes off.

According to a fourth aspect of the present invention, there is provided an opening / closing mechanism for a lid,
In order to solve the above-mentioned problem, in the lid opening / closing mechanism according to claim 1, 2 or 3, the opposing member has a side plate extending in both directions from both ends of the opposing portion in a storage direction. On the other hand, a slide support plate for slidably supporting the outer appearance of the lid is provided at an end of the facing portion at the facing portion of the facing member. It is characterized by being rotatably supported at a second support point provided.

According to the above invention, the facing member has a substantially U-shaped planar shape in which the side plates extend in the storage direction from both ends of the facing portion and are supported on both side surfaces of the storage portion at the first fulcrum. Formed.

That is, the opposing member is pivotally supported on both sides of the storage portion at the first fulcrum. For this reason, even if the object to be stored presses the facing portion, the facing member is strong in strength, so that the facing portion can be prevented from bending.
For this reason, it is possible to prevent the slide lock of the lid outer portion from easily coming off.

In particular, when the lid outer portion is formed of a resin, the resin is degraded due to the repeated opening and closing of the lid, and the locking is easily released, so that the above effect is large. Therefore, it is possible to provide a lid opening / closing mechanism that is excellent in durability.

A slide support plate for slidably supporting the outer appearance of the lid is rotatably supported at a second fulcrum provided at an end of the facing portion.

With this configuration, when the lid is opened around the first fulcrum, the outer appearance of the lid can be rotated about the second fulcrum, so that when the lid is opened to the maximum, the lid can be opened. The external part can be prevented from contacting the device body.

In the state where the urging means is pressing the object to be stored, the urging means is attached to the slide support plate, so that the slide lock of the outer appearance of the lid is formed. When it comes off, the slide support plate
By rotating about the fulcrum, the urging means moves outward in the storage direction, and the urging force of the urging means on the object to be stored is reduced. Therefore, when the lid is opened against the urging force of the urging means, the lid can be easily opened.

According to a fifth aspect of the present invention, there is provided a lid opening / closing mechanism,
In order to solve the above-mentioned problem, in the lid opening and closing mechanism according to claim 4, the slide support plate is provided with an elastic member, and in a state where the lid closes the storage portion, the slide support plate is On the other hand, when the elastic member is brought into contact with the facing portion in an elastically deformed state, when the locking of the lid external portion with the device body is released, the elastic deformation of the elastic member is released, and the slide support plate is moved to the second position. It is characterized by rotating at two fulcrums.

According to the above invention, the elastic member is provided on the slide support plate, and when the lid closes the storage portion, the slide support plate is opposed to the opposing portion with the elastic member elastically deformed. On the other hand, when the engagement of the lid external part with the device body is released, the elastic deformation of the elastic member is released, and the slide support plate rotates at the second fulcrum.

For this reason, when the slide lock of the lid outer part is released, the slide support plate is immediately rotated at the second fulcrum by the elastic member, and the lid outer part integrated with the slide support plate is rotated. Also rotates immediately.

Therefore, when the lid is opened about the first fulcrum, the outer appearance of the lid can always be rotated about the second fulcrum, so that when the lid is opened to the maximum,
It is possible to reliably prevent the outer appearance of the lid from coming into contact with the device body.

The opening and closing mechanism of the lid according to the invention according to claim 6 is
In order to solve the above problems, any one of claims 1 to 5
In the lid opening / closing mechanism according to the above item, the object to be stored is a battery, and an opposing portion of an opposing member is provided with a biasing means made of metal supported by the opposing portion and pressing the stored battery.

The reverse is also acceptable. That is, a shaft may be provided on the side wall 7b of the housing portion of the main body frame 7 while a shaft hole may be formed in the side plate 12b of the facing member.

The facing plate 12a and the facing member side plates 12b, 12b are formed in a substantially U-shape in plan view (see FIG. 7). In the above description, the side plate extends in the storage direction from both ends of the facing plate 12a and has a substantially U-shape in plan view. However, the present invention is not limited to this. It is also possible to form it into a substantially L-shaped planar shape that includes only one of the extending facing member side plates 12b.

The circumference of the first shafts 12c, 12c of the facing member side plates 12b, 12b is formed in a circular shape. Projections 12d inserted into the arc-shaped guide holes 7d are formed respectively.

Further, second shafts 12e, 12e serving as second fulcrums are formed at ends of the facing member side plates 12b, 12b opposite to the first shafts 12c, 12c, respectively. 12e is a slide support plate 1

The spring portion 13d is configured to abut on the back surface of the facing plate 12a of the facing member 12. When the lid outer portion 11 is in the closed state, the slide support plate 13 is in contact with the facing plate 12a of the facing member 12, so that the spring portion 13d is in contact with the facing plate 12a in an elastically deformed state. You. Further, as described later, when the engagement of the lid outer portion 11 with the device main body 2 is released, the elastic deformation of the spring portion 13d is released, so that the slide support plate 13 is moved to the second shaft 12e. -It rotates about 12e (see FIG. 1 (c)).

This is because the slide support plate 13
Without rotating around the second shafts 12e.
If the battery lid 10 is rotated about the first shafts 12c as it is, the Ω-shaped urging portion 13c may bite into the step of the negative concave electrode terminals 22 of the rechargeable battery 20. Further, there is a possibility that the lower part of the lid exterior part 11 also contacts the lower part of the main body cabinet 8. Therefore, in the present embodiment, the slide support plate 13 is forcibly rotated about the second shafts 12e, 12e by the spring portion 13d, so that the slide support plate 13 and the rechargeable battery 20 at the time of rotation of the battery cover 10 are connected. This is to prevent or reduce interference.

The slide support plate 13 is formed with, for example, two locking claw portions 13e at the upper portion thereof, and these locking claw portions 13e and 13e are provided on the facing plate 12 of the facing member 12. In order to restrict the rotation of the slide support plate 13 about the second shafts 12e at a fixed angle by locking the locked portions 12h formed at the upper end of the hook 12a, a hook shape is formed. It is hanging.

This pressing force is received by the facing member 12. For this reason, the load applied to the locking projections 11c of the resin exterior body 11 is reduced. Therefore, the lid exterior part 11
Is prevented as compared with the related art.

Further, the locking projection 11 of the lid exterior portion 11
c · 11c are locking recesses 8a · 8a of the main body cabinet 8
FIG. 5
As shown in FIG. 7A, the C-shaped projecting portion 13f of the slide support plate 13 is located below the mountain 11a of the cover exterior portion 11. For this reason, the downward movement of the lid exterior part 11 is locked by the crests 11a, so that the locking projections 11c of the lid exterior part 11 are locked by the locking recesses 8a of the main body cabinet 8. 8a does not easily come off.

Next, in order to open the lid outer part 11 from the state where the lid outer part 11 is closed, a finger is pressed from the outside of the lid outer part 11 to push the lid outer part 11 with an arrow. Move down in the A direction. As a result, as shown in FIG. 5 (b), the V-shaped protrusion 13f of the slide support plate 13 goes over the ridge 11a of the lid exterior part 11, and as shown in FIG. In the upper part, the engagement with the locking recesses 8a of the main body cabinet 8 is released at the upper part, and at the lower part, the inner platen projection 11d and the facing plate locked part of the facing plate 12a are released. The lock with 12g is released.

When the locks are released in this manner, as shown in FIG. 1C, the slide support plate 13 is centered on the second shaft 12e by the spring force of the spring portion 13d of the slide support plate 13. As a result, the cover body 11 rotates in a direction away from the main body cabinet 8, that is, in the direction of arrow B, whereby the lid outer portion 11 integrated with the slide support plate 13 also rotates.

At this time, the slide support plate 13
The Ω-shaped urging portion 13 c is in contact with the concave concave electrode terminal 22 formed in the rechargeable battery 20. That is, in the present embodiment, the locking projections 11c of the cover exterior part 11 and the locking recess 8a of the main body cabinet 8 should be used.
-Even if the engagement with 8a is disengaged and the cover exterior part 11 shown in FIG. 1C is slightly opened, the minus concave electrode terminal 22 and the Ω-shaped urging part 13c are in contact with each other. As a result, the electrical connection is maintained.

Here, in the present embodiment, the position where the first shafts 12c, 12c serving as the main pivotal centers of the battery lid 10 are attached is within the thickness of the rechargeable battery 20.
For this reason, even if the slide lock of the cover exterior part 11 is released, the battery cover 10 does not easily rotate around the first shaft 12c. That is, for example, the first shaft 12
If c is outside the thickness of the rechargeable battery 20, the rechargeable battery 2
0, the distance between the point of action of the pressing force and the first shaft 12c is increased, and the rotational moment is increased.
Are easy to rotate about the first shaft 12c. For example,
As shown in FIG.
When the battery 1 is located outside the extension surface of the rechargeable battery 52 in the storage direction, it can be said that the battery cover 50 has a structure that is easy to open.

On the other hand, in the present embodiment, as described above, the position at which the first shafts 12c are attached is within the thickness of the rechargeable battery 20, so that the cover exterior portion 11 Is difficult to rotate.

Next, when the downward pressing of the lid outer part 11 is continued from this state, the battery lid 10 including the lid outer part 11 and the Ω-shaped urging part 13c is as shown in FIG. To

1C, and rotates in the direction of arrow C about the first shaft 12c passing through the bottom of the main body cabinet 8 as shown in FIG.

Here, the battery cover 10 is connected to the first shaft 12c.
When sunk into the bottom side of the main body cabinet 8 with the center as the center, the Ω-shaped urging portion 13 c slides on the negative concave electrode terminal 22 of the rechargeable battery 20, and eventually separates from the negative concave electrode terminal 22 to electrically connect the rechargeable battery 20. The connection is disconnected,
As a result, power supply from the rechargeable battery 20 to a device circuit (not shown) is cut off. Further, the Ω-shaped urging portion 13 c rotates through the recessed step, and eventually sinks into the bottom side of the main body cabinet 8.

At this time, in the present embodiment, the slide support plate 13 to which the Ω-shaped urging portion 13c is attached rotates about the second shafts 12e, 12e, and the Ω-shaped urging portion 13c
Also moves outward in the storage direction of the rechargeable battery 20. Therefore, Ω
Although the character urging portion 13c is in contact with the negative concave electrode terminals 22 and 22, the urging force is weakened. As a result, the battery cover 1 can be provided without providing the second shaft 12e.
The rotation operation is easier to perform than rotating 0.

Further, in the present embodiment, the lid outer portion 1
1 is formed in a substantially L-shaped cross section, so that the opening dimension of the main body cabinet 8 on the bottom side is set at a position away from the rotation locus of the Ω-shaped urging portion 13c. by this,
When the battery cover 10 rotates, the battery cover 10 can rotate without contacting the main body cabinet 8 on the bottom side, and it can be prevented from being scratched or damaged due to twisting.

The rotation range of the battery lid 10, that is, the rotation range of the facing plate 12a, is shown in FIGS. 1 (a) and 1 (b). From the state where the locking projections 11c of the portion 11 are locked and the lid exterior portion 11 is in close contact with the main body cabinet 8, as shown in FIG. 1 (e), the facing member 12 is centered on the first shaft 12c. Up to about 90 °. That is, the upper end portion 7e of the arc-shaped guide hole 7d in the storage portion side wall 7b.
Then, the projection 12d of the opposing member side plate 12b abuts and functions as a stopper. In addition, the battery housing can be opened by rotating about 90 ° so that the rechargeable battery 20 can be taken out and inserted.

By opening the battery cover 10 as described above,
The rechargeable battery 20, which is the power source of the portable MD recorder 1, can be easily put in and taken out with the battery cover 10 opened. When the battery cover 10 is closed, the reverse operation may be performed.

As described above, in the cover opening / closing mechanism of the present embodiment, the battery cover 10 slides with respect to the device main body 2 to open and close the main body frame 7 in which the rechargeable battery 20 is stored. Assembled rotatably.

The battery cover 10 is provided with an opposing plate 12a and a slide support plate 13 which stand in the vicinity of the opening of the main body frame 7 in the storage direction of the rechargeable battery 20 and an end of the opposing plate 12a. Opposing member side plates 12b, 12b extending in the storage direction and supported by the storage portion side walls 7b, 7b of the main body frame 7 with the first shafts 12c, 12c and rotated in parallel to the storage portion side walls 7b, 7b. And a cover external part which is slidably supported by the slide support plate 13 on the outer side of the slide support plate 13 in the storage direction and which is locked to the device body 2 at an end thereof. 11 are provided.

That is, the facing plate 12a and the slide supporting plate 13 are erected in the vicinity of the opening of the main body frame 7 in the storage direction of the rechargeable battery 20, and the facing plate 12a is an end of the facing plate 12a. It extends in the storage direction from the portion and is pivotally supported on the storage portion side walls 7b by first shafts 12c. Further, the facing member side plates 12b, 12b
It is rotated in parallel with the housing side walls 7b.

Therefore, the storage direction of the rechargeable battery 20 and the opening and closing directions of the facing plate 12a and the slide support plate 13 are orthogonal and different. For this reason, even if the rechargeable battery 20 attempts to fly out, the facing plate 12a and the slide support plate 13 only stand and close, and do not contribute to opening. For this reason,
Battery cover 10 does not open easily.

Further, the lid outer portion 11 is slidably supported on the slide support plate 13 on the outer side in the storage direction, and the device main body 2 is held by locking projections 11c at its ends.
Are locked in the locking recesses 8a of the main body cabinet 8 in FIG. That is, the slide lock is performed. For this reason, the direction in which the rechargeable battery 20 is stored and the direction in which the lid exterior part 11 is locked to the locking recesses 8a of the main body cabinet 8 are also orthogonal and different. Therefore, the locking of the lid exterior portion 11 to the locking recesses 8a of the main body cabinet 8 does not easily come off.

As a result, the facing member 12 and the cover outer portion 1
In any one of the cases, the storage direction of the rechargeable battery 20 is different from the opening / closing direction and the locking direction, and the battery cover 10 does not open from the device main body 2.

In opening and closing, the lid outer portion 11 is slid to release the locking of the locking projections 11c, 11c into the locking recesses 8a, 8a of the main body cabinet 8, and then the lid outer portion. It is only necessary to rotate the entire battery cover 10 composed of 11 and the opposing member 12 about the first shafts 12c.

Therefore, the opening / closing operation of the battery cover 10 is simple, the slide lock of the battery cover 10 is hardly released, and the rechargeable battery 20 can be prevented from falling off immediately after the slide lock of the battery cover 10 is released. An opening and closing mechanism can be provided.

On the other hand, the battery cover 10 has the first shafts 12c and 12c.
Is opened and closed by pivoting around the center.
As the positions of the shafts 12c move outward from the thickness of the rechargeable battery 20, the first shafts 12c
The distance between the opposing plate 12a and the slide support plate 13 that is pressed by 0 increases, the rotational moment increases, and the opposing plate 12a and the slide support plate 13 easily rotate. This means that the battery cover 10 is easily opened.

However, in the present embodiment, the first shaft holes 7c are formed in the side walls 7b of the housing portion of the main body frame 7.
Since 7c exists at a position within the thickness dimension of the rechargeable battery 20, the rotational moment can be suppressed small, and the battery cover 10 can be prevented from being easily opened.

Further, the first shaft holes 7c serving as the center of rotation
Is provided at a position outside the thickness dimension of the rechargeable battery 20, the device body 2 becomes large, but in the present embodiment, the first shaft hole 7 is provided.
Since c and 7c are provided at positions within the thickness dimension of the rechargeable battery 20, the size of the device main body 2 can be reduced.

As a result, the slide lock of the battery cover 10 is not easily released, and even if the slide lock of the battery cover 10 is released, it is possible to prevent the rechargeable battery 20 from dropping off immediately. Can be provided.
