DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, an on-vehicle disk changer and other electronic devices, and more particularly to a slide door device in which an opening formed in a housing is closed by two doors.

[0002]

2. Description of the Related Art FIG. 5 is a transparent front view showing the internal structure of a vehicle-mounted disk changer, and FIG. 6 is a front view showing the front surface of a housing of the disk changer shown in FIG. In the disc changer shown in FIG. 5, a magazine M containing a plurality of discs (for example, compact discs) D is loaded in the housing 3. The selected disk D is partially pulled out from the magazine M stored in the housing 3 by a distance slightly longer than its radius, and the center of the selected disk D is a clamp unit provided on the rotation shaft of the spindle motor Mt. Clamped to C. Then, the recorded information is read by the pickup P facing the recording surface of the disk D driven by the spindle motor Mt. An opening 1 into which a magazine M is inserted as shown in FIG.
Are formed, and a sliding door 2 for closing the opening 1 is provided.

In the disk changer having the structure shown in FIG. 5, the selected disk D is not completely pulled out of the magazine M, but only a part thereof is pulled out and clamped by the clamp portion C. Accordingly, the overall width Wa of the housing 3 is smaller than twice the width W of the magazine M, and the overall size is reduced. In this case, since the width Wb of the opening 1 of the housing 3 shown in FIG. 6 must be larger than the width of the magazine M,
The width Wb of the opening is also larger than １ ／ of the entire width Wa of the housing 3.

Therefore, as shown in FIG. 6, if the door 2 for closing the opening 1 is of a single structure, the door 2 is slid rightward in the drawing to open the opening 1. The right end of the door 2 projects outside the housing 3. Therefore, as a sliding door device for opening and closing the opening 1 of this type of housing 3, a two-piece door is used, and the opening 1 is closed by the two doors, and the two doors are stacked when opened. It is conceivable to store it at a position outside the opening 1.

[0005]

However, when a sliding door device having a two-sheet structure is used, when the door is opened, the two doors are stacked one on another at a position deviating from the opening 1 and are stored. When the opening 1 is closed by these two doors, a step appears between the two doors. When the two doors slide on the outer surface of the housing 3, not only a step is formed between the two doors, but also a step is formed between the door and the outer surface of the housing 3. Due to the formation, the number of steps is increased, and the appearance as a product becomes very poor. In addition, when the doors are opened, the two doors are positioned overlapping on the outside of the housing, so that the two overlapping doors protrude greatly from the outer surface of the housing, and luggage or the like is placed in a portion adjacent to the housing. If this is the case, it will interfere with the opening and closing operation of the door.

Conversely, when the two doors slide inside the housing 3, the outer surface of the door in the closed state is located more inward than the outer surface of the housing 3. Opening 1
Large depressions are formed, not only the appearance is reduced,
There is a drawback that dust and the like easily accumulate in the recess. Another problem is that, in a two-slide sliding door device, since each of the two doors slides individually, a guide portion for guiding each door to the housing is individually provided. And the structure of the guide portion of the door becomes complicated.

Further, in a structure in which two doors are provided inside the housing 3 and a guide groove is formed in the housing as a guide portion, and a projection provided on the door slides in the guide groove.
When the door is pressed with a strong force from the outside in a state where the door closes the opening 1, the projection provided on the door comes off from the inside of the guide groove, and the opening and closing sliding of the door becomes impossible. Problems are easy to occur.

The present invention has been made to solve the above-mentioned conventional problems, and when the opening is closed by two doors, the step between the two doors is reduced, or each door and the outer surface of the housing are provided. It is an object of the present invention to provide a sliding door device that can be made to be substantially flush with each other.

Another object of the present invention is to provide a slide door device which simplifies the structure of a guide portion for slidably guiding two doors, for example, so that the number of guide grooves provided on the housing side can be minimized. It is an object.

Another object of the present invention is to provide a slide door device which can prevent a projection provided on a door from coming off a guide groove even when an external force acts on each door.

[0011]

SUMMARY OF THE INVENTION A sliding door device according to the present invention moves between a position where a part of an opening formed in a housing is closed and a storage position where the housing is housed inside a wall surface of the housing. A first door to be closed, a second door moving between a position for closing the remaining area not closed by the first door at the opening and the storage position, and a closing direction from the storage position. A guide portion for moving the first door along the inside of the wall surface and moving the first door toward the outside of the housing when reaching the closed position, and the second door closing in the closing direction from the storage position is closed And a guide portion for moving the second door toward the outside of the housing when it reaches the position.

In the above, preferably, when the opening is closed by the first door and the second door, the outer surface of the first door, the outer surface of the second door, and the outer surface of the housing Are located on substantially the same plane.

In the present invention, the first door and the second door are deployed in the opening, so that the opening is closed by the two doors. When the door is opened, the first door and the second door are in the housing. At the position deviating from the opening. In the state where the opening is closed, both doors are guided so as to move to the outside of the housing, so that the portions of both doors do not form a depression in the opening, and preferably the first door and the first door are not closed. All outer surfaces of the second door and the housing are substantially flush. Therefore, the appearance of the housing is improved,
In addition, since a large step or depression is not generated in the opening, a structure in which dust hardly accumulates is obtained.

Further, in the present invention, the guide groove for guiding the projection on the rear side of the second door when the direction of travel of the door when moving in the closing direction is the front part and the direction opposite to this is the rear part. Is provided in the first door, and the guide groove is provided so that the second door can be moved toward the outside of the housing when the second door reaches the closed position. A bent portion that bends toward the first direction, and when the first door and the second door are moved in the opening direction at the initial point when the second door is moved in the opening direction starting from the closed state, It is possible to provide a restricting portion for restricting the movement of the second door in a direction away from the second door.

In this structure, when a force in the opening direction is applied to the second door in a state in which the opening of the casing is closed by the first door and the second door, the first door is first opened. The second door and the second door move together in the opening direction without changing their relative positions, and after the restriction on the second door is released, the second door is moved to the first door. Door can overlap. In this way, if the first door and the second door are always moved together in the opening direction at the beginning, the door always moves in the same way at the time of purchase of the product and at the time of the lapse of time. It can give a sense of stability. That is, in the case of using two doors, the operation is always performed such that one door may start moving at first or two doors may start moving together due to a change in friction coefficient between the doors. Although it may be different and may give a sense of instability to the operation of the product, in the present invention, at first the two doors always move together, so that a sense of stability of the operation can be given.

Further, according to the present invention, when the traveling direction of the door when moving in the closing direction is the front portion and the opposite direction is the rear portion, the guide portion is provided in the housing and the first door is provided. A first guide groove for commonly guiding the projection on the front side of the first door and the projection on the front side of the second door; and a second guide groove provided in the housing and guiding the rear projection on the first door. And a third guide groove provided in the first door and guiding the rear projection of the second door.

In the above, the ends of the second guide groove and the third guide groove facing the opening side have the first position reaching the closed position.
The door and the second door are provided with a bent portion that bends outward so that the door and the second door can be moved to the outside of the housing. Can be moved toward the outside of the housing.

In the present invention, the first device provided on the housing side
The guide grooves of the two doors guide the protrusions of the two doors, and the protrusion on the rear side of the second door is guided by the guide grooves of the first door. Therefore, two guide grooves are formed on the housing side. Alone, the number of guide grooves can be minimized, and the structure of the housing can be simplified.

Further, according to the present invention, the guide portion is a guide groove in which a projection provided on each door slides, and when the first door and the second door reach the closed position, the projection is formed. Is provided on each door so that the door does not come off the guide groove.

When such a restricting portion is provided, when the opening is closed by the first door and the second door provided inside the housing, one of the doors is subjected to strong external force. Even if the door is pushed, the door does not come off from the guide groove, and it is possible to prevent the occurrence of troubles such as the inability to open and close the door.

The outer surface (X2 direction) of the regulating protrusion 17 is a regulating portion 17a, a regulating portion 17b, and an inclined portion 17c. The restricting portion 17a is formed parallel to the guide portion of the first guide groove 15 and has the same inclination angle α. The restricting portion 17b is parallel to the guide portion of the first guide groove 15, and is therefore parallel to Y1-Y2. The inclined portion 17c is parallel to the guide portion of the first guide groove 15, and has an inclination angle of β.

FIG. 1 shows a state in which the opening 12 is closed by the first door 20 and the second door 30, but FIG.
Here, the doors 20 and 30 are omitted. FIG. 3A shows the doors 20 and 30 in the closed state of FIG.
It is shown in an enlarged cross section taken along line -II.

The first door 20 is made of a synthetic resin.
Is a U-shape or a curved shape in a plane orthogonal to the plane of the drawing. As a result, the interior (a) is a concave space. In the planar shape shown in FIG. 3A, the outer surface 21 of the first door 20 is the outer surface 11b of the front surface 11 of the housing 10.
Is parallel to The portion of the outer surface 21 on the Y2 side is an inclined surface 22 directed inward (X1 direction) of the housing 10.
A projection 23 is provided at the tip of the first door 20 (portion on the Y1 side), and the projection 23 is provided in the first guide groove 15.
It is slidably inserted in the inside. A projection 24 is provided on a rear portion (Y2 side portion) of the first door 20, and the projection 24 is slidably inserted into the second guide groove 16.

A third guide groove 25 is formed in the inner surface of the first door 20 in a concave or penetrating long hole shape. The guide groove 25 has a guide portion and a guide portion formed continuously in the closing direction (in the Y1 direction). The guide portion is parallel to the outer surface 21 of the first door 20, and in the closed state shown in FIG.
The guide is parallel to Y1-Y2. The guide portion is an inclined groove directed outward (X2 direction) as it advances in the closing direction (Y1 direction), and its inclination angle is larger than the aforementioned β,
This guide portion is a bent portion.

The second door 30 is also made of synthetic resin and is housed inside the inner wall surface 11a of the front surface 11 of the housing 10 and inside the first door 20 in the housed state shown in FIG. Shape. Outer surface 31 of second door 30
Is the same surface as the outer surface 21 of the first door 20 in the closed state shown in FIG.
1b, and therefore a plane parallel to Y1-Y2.

The rear portion (Y2 side portion) of the outer surface 31 of the second door 30 is a curved surface 32 that has entered the inside (A) of the first door 20. In addition, a handle 33 is formed in a convex shape at a tip portion (Y1 side portion) of the outer surface 31. Second
A projection 34 is integrally formed at the front end of the door 30, and the projection 34 is slidably inserted into the first guide groove 15. That is, the first guide groove 15 is provided with the projection 23 provided at the tip of the first door 20.
And a projection 34 provided at the tip of the second door 30 are slidably inserted in common. Second door 3
0 is provided with a projection 35 at the rear portion.
Is slidably inserted into a third guide groove 25 formed in the first door 20.

Next, the operation of the slide door device provided in the disc changer will be described. FIG.
Shows a state in which the first door 20 and the second door 30 slide to each other in the Y2 direction and move to an open position where the first door 20 and the second door 30 come off the opening 12. In this open position, the projection 24 at the rear of the first door 20 is connected to the second guide groove 1 provided in the housing 10.
6 is located at the end on the Y2 side of the guide portion, and the projection 23 at the tip of the first door 20 is located on the Y2 side end of the guide portion of the first guide groove 15 provided in the housing 10. Therefore, the first door 20 is located inside the inner wall surface 11 a of the front surface 11 of the housing 10 at a position separated from the opening 12. Further, a protrusion 35 provided at the rear of the second door 30 is provided with a third guide groove 25 formed in the first door 20.
Is moved to the end on the Y2 side of the guide portion, and the protrusion 34 provided at the tip of the second door 30 is located at the guide portion of the first guide groove 15. Therefore, the second door 30 is housed so as to be separated from the opening 12 of the housing 10 and positioned inside the inner wall surface 11 a and inside the first door 20.

In the storage position shown in FIG.
The handle 33 located at the end on the Y1 side of the outer surface 31 is exposed to the Y1 side from the first door 20 and is in a position where it can be operated from the outside. Hold this handle 33 in the closing direction (Y1 direction).
Then, the second door 30 moves in the Y1 direction, and accordingly, the first door 20 also slides in the Y1 direction.

While the second door 30 reaches the closed position shown in FIG. 3A, the projection 34 at the front end of the second door 30 is moved to the first position.
Of the guide groove 15 inclined in the X2 direction is moved from the guide portion inclined in the X2 direction. Then, in the closed state shown in FIG. 3A, the protrusion 34 moves to the end on the Y1 side of the guide portion, and the tip of the second door 30 moves outward (X2 direction). Further, the protrusion 35 provided at the rear of the second door 30 moves to the leading end of the guide portion (bent portion) of the third guide groove 25 of the first door 20, and
The rear part of the door 30 moves outward (X2 direction). As a result, the second door 30 in the closed position is the first door 2
0, moves outward (in the X2 direction), and the outer surface 31 of the second door 30 becomes the outer surface 11b of the front surface 11 of the housing 10.
And the same plane or almost the same plane.

Further, when the first door 20 moves to the closed position, the projection 23 provided at the tip of the first door 20 moves through the first guide groove 15 formed in the housing 10, and the first door 20 moves as shown in FIG. In the closed position shown in (), the projection 23 has moved to the guide portion of the first guide groove 15. The tip of the first door 20 moves outward (X2) by the movement of the projection 23 in the inclined guide portion.
Direction). Also, the first door 20
The projection 24 at the rear portion of the second guide groove 16 is shifted from the guide portion of the second guide groove 16 to a guide portion (bent portion). Therefore, due to the inclination of the guide portion of the first guide groove 15 and the inclination of the guide portion of the second guide groove 16, the first door 20 in the closed position shown in FIG. ), And as a result, the outer surface 21 of the first door 20 is flush with or substantially flush with both the outer surface 31 of the second door 30 and the outer surface 11b of the front surface 11 of the housing 10. I have.

In the closed state shown in FIG. 3A, as described above, the outer surface 21 of the first door 20, the outer surface 31 of the second door 30, and the outer surface 11b of the housing 10 are all flush. Alternatively, since the surfaces are almost the same, no large uneven surface appears on the front surface 11 of the housing 10 and no dent is formed in the opening 12, so that the appearance of the product is improved. Further, since no depression is formed, dust and the like hardly accumulate in the closed opening 12.

In the closed state shown in FIG. 3A, the restricting portion 17a of the restricting protrusion 17 is provided at the back of the door 30 at the portion (b) near the protrusion 34 on the front side of the second door 30. Are facing each other. Therefore, even if the second door 30 is strongly pushed in the X1 direction from the outside of the housing 10, the second door 30 is regulated by the regulating portion 17a at the portion (b), and the projection 34 is moved to the first position. The guide groove 15 does not come off. Similarly, in the portion (c) where the projection 23 on the front end side of the first door 20 is provided, the regulating projection 17 is provided on the back surface of the first door 20.
Are opposed to each other. Therefore, the first door 2
Even if 0 is strongly pushed in the X1 direction, the protrusion 23 does not come off the first guide groove 15. Since the projections of the doors 20 and 30 in the closed state are not disengaged from the guide grooves 15, the doors cannot be opened even when an external force acts.

Next, when opening the door, FIG.
(A) Pull the handle 33 of the second door 30 in the closed state in the opening direction (Y2 direction) with a finger. The second door 30 is Y
While moving in the two directions, the protrusion 35 provided at the rear of the second door 30 tends to escape from the guide portion (bent portion) of the third guide groove 25 formed in the first door 20. However, since the projection 34 provided at the tip of the second door 30 is located at the end of the guide portion of the first guide groove 15 on the Y1 side, the entire second door 30 is moved in the X2 direction. I'm moving. Furthermore, on the back surface of the second door 30, the side 30a is parallel to Y1-Y2 in the state of FIG. 3A, and the side 30b further than that is inclined shallowly in the X2 direction toward the Y1 direction,
The portion (b) is the boundary (corner). Therefore, in the state of FIG.
When the door 30 is about to rotate in the φ direction, (b)
Is restricted by the restricting portion 17a and its rotation angle is slight. Therefore, the second door 3 moving in the Y2 direction
0 cannot sufficiently enter the inside (a) of the first door 20, the protrusion 35 does not come out of the guide portion, and the second
When the door 30 starts moving in the Y2 direction, the first door 20 also starts moving in the Y2 direction.

FIG. 3B shows a state in which the second door 30 has slightly moved in the Y2 direction. Even at this time, the second door 30 has not largely moved in the X1 direction. At this time, the projection 35 does not come off the guide. Therefore, FIG.
Even at the time point (B), the first door 20 moves in the Y2 direction together with the second door 30.

Since the guide portion of the first guide groove 15 is inclined in the X1 direction as it advances in the Y2 direction, the entire second door 30 moves in the X1 direction as it moves in the Y2 direction. I do. The movement of the entire second door 30 in the X1 direction and the slight rotation in the φ direction with the projection 34 as a fulcrum further move the second door 30 to Y2.
When it moves in the direction, the rear part of the second door 30 can enter the inside (A) of the first door 20 and the projection 35
Can escape from the guide. First
When the door 20 reaches the position shown in FIG. 3 (C), the projection 35 may come out of the guide portion. However, in practice, the first door 20 and the second door 30 are put together in FIG. If the second door 30 moves further in the Y2 direction than C), the portion (b) comes off the restricting portion 17a, so that the second door 30 can be largely rotated in the φ direction. It becomes easy to enter the inside (a) of the first door 20.

After the projection 35 comes off from the guide portion, the second door 30 first enters the inside (a) of the first door 20, and then both the doors 20 and 30 move together in the Y2 direction. Alternatively, after the projection 35 is disengaged from the guide portion, the first door 20 and the second door 30 move together in the Y2 direction without changing their relative positions. In any case, when the first door 20 moves in the Y2 direction, the protrusion 2
4 is disengaged from the guide portion of the second guide groove 16 and reaches the guide portion, and as shown in FIG.
The first door 20 is housed inside the inner wall surface 11 b of the front surface 11, and the second door 30 is further housed inside the first door 20. As a result, the opening 12 is widely opened, and the magazine can be loaded.

In the above configuration example, when the handle 33 is gripped and the second door 30 is pulled in the Y2 direction from the closed state in FIG. 3A, the first door 20 and the second door 30 are initially connected. Because the door 30 moves without changing its relative position,
The operational feeling is always stable and the operational feeling is improved. That is,
When the handle 33 is pulled in the Y2 direction, the second door 30
If the operation is different depending on the case, such as when only the door alone moves in the Y2 direction, or when both doors 20 and 30 move together in the Y2 direction, the operation of the apparatus is stable for the operator. However, in the above configuration example, both doors 20 and 30
Start moving together, so that such a feeling of strangeness is not felt.

In the above configuration example, the on-vehicle disc changer has been described as an example, but the disc to be loaded may be a magazine containing compact discs (CDs).
Alternatively, a magazine containing a plurality of minidiscs (MDs) may be used, or a plurality of MDs or the like may be individually inserted. The present invention is not limited to the in-vehicle disk changer, but can be applied to various in-vehicle equipment, home electronic equipment, office electronic equipment, and the like.

[0046]

As described above, according to the present invention, in the sliding door device in which the opening is closed by the two doors, the two doors are stored inside the wall of the housing in the open state. The two doors do not protrude outside the housing with a step, so that even if luggage or the like is placed adjacent to the housing, the opening / closing operation is not hindered. When two doors are closed from the inside of the opening, each door moves toward the outside of the housing at the time of closing. Preferably, both doors and the outer surface of the housing are substantially flush with each other. Steps and depressions do not appear on the surface, and the appearance is improved, and problems such as accumulation of dust in the depressions are eliminated.

If the first door and the second door always slide together at the beginning when the second door is opened, the operational feeling when the door is opened is improved.

Further, a guide groove is formed in which the projections of the first door and the second door slide in common.
When the guide groove of the door is formed, only the first and second guide grooves on the housing side can be provided as in the illustrated configuration example, and the structure of the housing can be simplified.

When the first door and the second door are in the closed state, the opposing restricting portions are provided inside the respective doors, so that when an external force is applied, the projections of the doors come out of the guide grooves. It is possible to prevent troubles such as the door not being opened and the door being unable to be opened.
