DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to, for example, a vertical C
The present invention relates to a slide door moving mechanism for sliding a slide door in a D player or the like, and an audio apparatus including such a slide door moving mechanism.

[0002]

2. Description of the Related Art For example, a vertical CD player is provided with a slide door for covering a disk rotating section, and the slide door can be opened and closed by being vertically moved in a vertical direction. ing.

FIGS. 11 and 12 are explanatory diagrams for explaining a conventional mechanism for moving a slide door.
In particular, FIG. 11 is a cross-sectional view with the sliding door closed.
FIG. 12 is a cross-sectional view showing a state in which the slide door is opened, but partially showing some members so that the internal structure can be clearly understood. As shown in these figures, the sliding door 10
As a sliding door moving mechanism for moving 0,
A rack 200 and a pinion 300 are generally used. The sliding door 100 is connected to the lower end 20 of the rack 200.
At a position where 0A meshes with the pinion 300, the disk rotation unit 110 is closed, and at a position where the upper end 200B of the rack 200 meshes with the pinion 300, the disk rotation unit 110 is opened. That is, the movement stroke S of the slide door 100 is uniquely determined according to the length R of the rack 200.

The lower end 200A of the rack 200
And the upper end portion 200B require a margin R1, R1 with the pinion 300, so that the sliding door 1
The length R of the rack 200 is slightly longer than the movement stroke S of 00. Therefore, in addition to the moving stroke S of the sliding door 100, the length R of the rack 200 that moves up and down, etc.
An internal space having a vertical dimension H in the vertical direction is secured.

[0005]

However, in the sliding door moving mechanism using the rack 200 and the pinion 300, it is necessary to secure the internal space of the vertical dimension H corresponding to the length R of the rack 200 as described above. However, under such dimensional restrictions, the size of the housing 120 cannot be reduced in the sliding direction, and the size of the entire apparatus cannot be reduced.

The rack 200 and the pinion 300
Since there is no lock mechanism, the user can forcibly push down the slide door 100 by hand. Then, there is a possibility that the disk rotating unit 110 is opened and the disk D rotating at a high speed is touched by hand.

Further, in order to make the movement of the slide door 100 excellent in quality, for example, a method is used in which the slide door 100 starts moving at a certain speed, then gradually decelerates from an intermediate position and finally stops. . However, of course, the rack 200 and the pinion 300 can only move by a constant speed motion consistently. Therefore, in order to change the movement of the slide door 100, it is necessary to provide a switch for detecting the deceleration position in addition to a switch for detecting the movement stop position, and change the rotation speed of the pinion 300 halfway. In adopting such a configuration, an increase in cost cannot be avoided.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been conceived in view of the above circumstances, and enables a reduction in the size of the entire apparatus, the movement of a sliding door that varies in quality, and a reliable door lock. It is an object of the present invention to provide a sliding door moving mechanism capable of realizing the above at low cost, and an audio apparatus provided with the sliding door moving mechanism.

In order to solve the above problems, the present invention provides:
The following technical measures have been taken:

That is, according to the first aspect of the present invention,
A sliding door moving mechanism for moving a sliding door along a predetermined sliding direction, comprising a slider frame integrated with the sliding door and movable along the sliding direction of the sliding door; A guide groove formed in an elongated shape along a direction orthogonal to the sliding direction of the slide door, and a swing arm whose distal end is guided by the guide groove and is rotatable around the base end. A drive system for transmitting a rotational drive force to a base end of the swing arm.

According to a preferred embodiment, the guide groove is
Two grooves, which are followers to each of the tip portions of the two swing arms, are arranged in series along the same straight line with each other. While being guided by the two guide grooves, they are rotated by approximately half in opposite directions according to the rotational driving force from the drive system.

According to another preferred embodiment, the two swing arms are arranged such that the center of rotation of each base end thereof is located on the same straight line parallel to the two guide grooves.

According to another preferred embodiment, the guide groove is a follower for each tip of the two swing arms.
The two oscillating arms are formed by obliquely arranging the two grooves at a constant parallel interval. The two oscillating arms are driven by a rotational driving force from a driving system while their respective tips are guided by the two guide grooves. In the opposite directions to each other.

According to another preferred embodiment, the two swing arms are arranged such that a straight line connecting the centers of rotation of their base ends forms an acute angle with a straight line parallel to the two guide grooves. I have.

[0015] According to another preferred embodiment, the guide groove is formed with a bent end portion which is bent as a whole at an outer end portion.

According to another preferred embodiment, the driving system includes an arm gear provided at each base end of the two swing arms, a synchronous gear connecting these arm gears to rotate in opposite directions, It comprises a drive motor that rotates freely in both directions to generate a rotational drive force, and a reduction gear train that reduces the rotational drive force from the drive motor and transmits it to either a synchronous gear or an arm gear.

According to another preferred embodiment, the slide door is reciprocated up and down in the vertical direction in conjunction with the rotation of the swing arm.

According to a second aspect of the present invention, there is provided an audio apparatus provided with a slide door moving mechanism for moving a slide door along a predetermined sliding direction, wherein the audio apparatus is integrated with the slide door and includes a slide door. A slider frame that is movable along the sliding direction of the door, a guide groove provided on the slider frame and formed in an elongated shape along a direction that intersects with the sliding direction of the sliding door, and a leading end of the guide groove. The swing door is guided and rotatable about a base end thereof, and a drive system for transmitting a rotational driving force to the base end of the swing arm is provided as a slide door moving mechanism. An audio device having a sliding door moving mechanism is provided.

According to a preferred embodiment, the slide door is for covering a vertical disk rotating portion for rotating the audio disk in a vertical plane, and is provided with a vertical door in conjunction with the rotation of the swing arm. Reciprocating up and down directions.

According to the present invention, when the two swing arms rotate, the tip of each swing arm is displaced in an arc while being guided by the guide groove, and the guide groove is used as a follower together with the slider frame. The sliding door moves in the sliding direction. In short, the rotational movement of the swing arm is converted into a linear movement of the slide door via the guide groove. For example, assuming that the rotation radius from the base end to the tip end of the swing arm is substantially equal to half of the moving stroke of the slide door, the slide door is moved to the uppermost position in response to the swing arm rotating substantially half a turn. Move up and down linearly from to the bottom position. At this time, the movement of the sliding door during movement changes to a fast state or a slow state according to the relative positional relationship between the tip of the swing arm and the guide groove.

Therefore, as the internal space, in addition to the space for moving the slider frame, a space size enough to allow the swing arm to rotate is required. However, this internal space is cut down as much as possible along the sliding direction to a minimum size. However, since the entire mechanism including the swing arm can be sufficiently accommodated, the size of the housing can be reduced in the sliding direction without being restricted by the dimensions, and the size of the entire apparatus can be reduced.

Further, when the swing arm is stopped almost straight along the sliding direction, the slide door is fixed by the degree of engagement between the guide groove and the tip of the swing arm. It does not move even if it is, and a reliable door lock can be realized. In particular,
If the guide groove is viewed as a whole and a nice bent end is formed at the outer end portion, the tip of the swing arm is positioned along the bent end to ensure the end. The sliding door can be fixed.

Further, even if the rotation speed of the swing arm is constant, the movement of the slide door changes in the middle depending on the relative positional relationship between the leading end portion and the guide groove. The movement of the sliding door, which changes dynamically, can be realized at low cost.

Other features and advantages of the present invention will become more apparent from the following description of embodiments of the present invention with reference to the accompanying drawings.

Of course, the sliding door 10 may be opaque and has no characteristic in its own characteristics or structure. In order to move the slide door 10 up and down in the vertical direction, a slide door moving mechanism (not shown) is built in the housing 12 of the audio device A, and the slide door 10 has a rail extending in the vertical direction. Groove 1
It is assembled to the sliding door moving mechanism through 3 and 13. Hereinafter, the slide door moving mechanism will be described in detail with reference to the drawings.

FIGS. 2 and 3 show an embodiment of the sliding door moving mechanism according to the present invention. FIG. 2 is a side sectional view showing the internal structure of the sliding door moving mechanism from the side. 3 is a rear sectional view showing the internal structure of the sliding door moving mechanism from the rear. In FIGS. 2 and 3, some members are shown transparently so that the internal structure can be easily understood, and some members or portions are not shown for convenience. As shown in these figures, the sliding door moving mechanism is provided for the sliding door 10, the slider frame 20, the two guide grooves 21, 22, the two swing arms 31, 32, and the two swing arms 31, 32. And a driving system 40 for transmitting a rotational driving force.

The slider frame 20 is provided with the sliding door 1.
0, and can be freely moved along the sliding direction in which the sliding door 10 moves up and down. Specifically,
The slider frame 20 is fixed to the right and left sides of the slide door 10 through rail grooves 13, 13 (not shown in FIGS. 2 and 3).
And a frame central portion 20A extending integrally in the left and right direction at the inner back without interfering with the frame.

The two guide grooves 21 and 22 are formed in the frame center portion 20A of the slider frame 20 so as to be elongated in the left-right direction, and are arranged in series along the same straight line. ing. In addition, each of the guide grooves 21 and 22 has a suitable bent end portion 21A, 22A which is slightly bent downward at a terminal portion on the outer side as a whole.
Are formed. The guide grooves 21 and 22 are not formed with openings, but may be formed with flanges.

The two swing arms 31 and 32 have front ends 31A and 32A in the guide grooves 21 and 22, respectively.
B, 32B so as to be connected to each other,
C and 32C are rotatably supported about the rotation centers 31D and 32D. Specifically, the two swing arms 31 and 32 are formed by two crank grooves 31 and 32 fixed to the tip portions 31A and 32A, respectively.
2 are symmetrically arranged so that they can be rotated by approximately half in opposite directions according to the rotational driving force from the driving system 40 while sliding along 2. Therefore, each swing arm 31, 32
Rotation centers 31D, 32 of the base ends 31C, 32C at
D is located on the same straight line parallel to the two guide grooves 21 and 22. In addition, the rotation center 31 of the base end portions 31C and 32C.
D, 32D to Crankpin 3 from tip 31A, 32A
The turning radii of the swing arms 31 and 32 up to 1B and 32B correspond to almost half of the moving stroke of the slide door 10. Further, the bent end portions 21A and 22A of the guide grooves 21 and 22 correspond to the turning radii of the swing arms 31 and 32 so as to match the locus drawn by the crank pins 31B and 32B when the swing arms 31 and 32 rotate. It is partially curved with substantially the same radius of curvature. Thus, in a state where the crank pins 31B and 32B are located along the end bent portions 21A and 22A, even if an external force is applied to the slide door 10, the slider frame 20 does not move up and down. In particular, FIG.
The left swing arm 31 can be rotated from a state in which the distal end portion 31A is positioned at the uppermost position to a state in which the distal end portion 31A is positioned at the lowermost position by substantially half-clockwise rotation. On the other hand, the right swing arm 32 is rotatable from a state in which the distal end portion 32A is positioned at the uppermost position to a state in which the distal end portion 32A is positioned at the lowermost position by substantially half-turning counterclockwise. Is done. The left and right swing arms 3
Although the rotation directions of 1, 32 are different from each other,
The rotation speed and the rotation angle are the same.

The drive system 40 includes an arm gear 4 formed on the outer periphery of each of the base ends 31C and 32 of the swing arms 31 and 32.
1, 42; two synchronous gears 43, 44 for connecting these arm gears 41, 42 to each other and rotating them in opposite directions;
A drive motor M that is rotatable in both forward and reverse directions to generate a rotational drive force; a belt 45 as a reduction gear train that transmits the rotational drive force from the drive motor M to one of the synchronous gears 43 while reducing the rotational drive force; Four reduction gears
7, 48 and the like. Specifically, with reference to FIG. 3, in the drive system 40, when the drive motor M rotates clockwise, the pulley gear 46
Also rotates clockwise, the reduction gear 47 meshing with this pulley gear 46 rotates counterclockwise, and the other reduction gear 48 meshing with this reduction gear 47 rotates clockwise, and the left gear meshing with this reduction gear 48 The synchronous gear 43 rotates counterclockwise, and the synchronous gear 43 and the arm gear 4
As the gears 1 mesh with each other, the left swing arm 31 rotates clockwise. At the same time, the right synchronous gear 44 rotates clockwise by meshing with the left synchronous gear 43, and the right swing arm 32 rotates counterclockwise by meshing the synchronous gear 44 and the arm gear 42. It is designed to be. Of course, when the drive motor M rotates counterclockwise, the left and right swing arms 31 and 32 rotate simultaneously in the opposite direction. The rotation direction of the drive motor M is switched according to a signal from a switch (not shown) that detects the position at which the slide door 10 stops moving, or the like.

Next, the operation of the sliding door moving mechanism will be described with reference to FIGS. 2 and 3 as well as other drawings.

FIGS. 4 to 7 are explanatory diagrams for explaining a series of movements in the sliding door moving mechanism. In particular, FIGS. 2 and 3 described above correspond to a state in which the sliding door 10 is closed, and FIGS. 4 and 5 correspond to states in which the sliding door 10 is almost half-open during the movement, FIGS. FIG. 7 is a diagram corresponding to a state where the slide door 10 is completely opened. Of these figures, FIG. 3, FIG. 5, and FIG. 7, in which the overall movement is most easily understood, will be described below as main reference figures.

First, as shown in FIG.
When the disk rotation unit 11 is completely closed, the left and right swing arms 31 and 32 stop at positions roughly pointing to 11:55 and 12: 5, respectively, when expressed by a clock. In this state, the drive motor M has stopped rotating. At this time, the crank pin 31B,
32B enters the bent end portions 21A and 22A of the guide grooves 21 and 22, so that each swing arm 31,
32 is in a state of being securely held.

That is, the end bent portions 21 of the guide grooves 21 and 22
A, 22A and tip portions 31A, 3 of swing arms 31, 32
Due to the degree of engagement with the crank pins 31B and 32B in 2A, for example, even if the slide door 10 is moved downward by hand, the swing arms 31 and 32 move in a fixed state without rotating. There is no.

Next, when the drive motor M rotates clockwise from the state shown in FIG. 3, a driving force that rotates in a predetermined direction is applied to the left and right swing arms 31 and 32, respectively. The tip portions 31A, 32A of the 32 are about to start moving diagonally downward. Then, the tip portions 31A, 3
The crank pins 31B and 32B in 2A are the guide grooves 2
The guide groove 2 starts to slide gradually along 1 and 22,
The slider frame 20 starts to move downward with the slaves 1 and 22 as followers. Therefore, the slide door 10 integrated with the slider frame 20 also starts to move downward.

Immediately after the start of the movement, the moving amount of the slide door 10 in the left and right directions along the guide grooves 21 and 22 of the crank pins 31B and 32B is larger than the moving amount in the vertical direction. The speed is set to low speed, and the sliding door 10 starts to descend slowly.

Further, the drive motor M rotates clockwise,
When the swing arms 31 and 32 on the left and right sides are in the middle of rotation at the passing positions indicating 3 o'clock and 9 o'clock respectively, as shown in FIG. 5, the crank pins 31B and 32B at the distal ends 31A and 32A are guided by the guide grooves. The state becomes closest to each other along the lines 21 and 22. At this time, the swing arms 31, 3
2 rotates at a constant rotation speed, but since the vertical movement amount of the crank pins 31B and 32B is maximum, the movement speed of the slide door 10 is also maximum, and the slide door 10 is moved at the highest speed. Descend.

Further, the drive motor M rotates clockwise,
When the swing arms 31, 32 on the left and right sides rotate, the amount of vertical movement of the crankpins 31B, 32B gradually decreases, so that the moving speed of the sliding door 10 gradually decreases, and the sliding door 10 slowly decelerates. 10 falls.

Finally, as shown in FIG. 7, when the left and right swing arms 31 and 32 reach a position indicating approximately 6 o'clock, the crank pins 31B and 32B are returned to the guide grooves 21 and 2 again.
2 is in a state where it has entered the end bent portions 21A and 22A,
The movement of the slide door 10 is stopped with the swing arms 31 and 32 securely held. As a result, the slide door 10 is in a state where the disk rotating unit 11 is completely opened.

The series of operations described above is accompanied by lowering the slide door 10 from the closed state to the open state. Conversely, the slide door 10 is changed from the open state to the closed state. In the case of ascending, the above-described series of operations may be reversed.

Therefore, according to the sliding door moving mechanism, as clearly shown in FIGS. 2 to 7, the internal space of the housing 12 has a space in which the slider frame 20 can move and a driving system 40 and the like. In addition to the installation space,
It is possible to secure a sufficient space for the swing arms 31 and 32 to rotate. Therefore, even if the internal space is cut infinitely in the vertical direction to have the minimum dimension H1 (see FIG. 3), all the components including the swing arms 31 and 32 can be sufficiently accommodated in the internal space, so that there is a restriction on the dimensions. The size of the housing 12 can be reduced in the vertical direction, and the size of the entire audio device A can be reduced.

When the swing arms 31 and 32 are stopped, the slide door 10 is fixed due to the engagement between the bent ends 21A and 22A of the guide grooves 21 and 22 and the crank pins 31B and 32B. Therefore, even if the slide door 10 is moved up and down by hand, it does not move, and a secure door lock can be realized.

Further, even if the rotational speed of the drive motor M is kept constant in order to keep the rotational speed of the swing arms 31 and 32 constant,
Immediately after the movement is started or immediately before the movement is stopped, the moving speed of the slide door 10 is low. On the other hand, the moving speed is high in a state where the sliding door 10 is moved almost in the middle of the moving stroke. That is, since the moving speed of the slide door 10 fluctuates according to the relative positional relationship between the swing arms 31 and 32 and the guide grooves 21 and 22, the movement of the slide door 10 that varies in quality is controlled by the swing arm. It can be realized at low cost only by a mechanical mechanism such as 31, 32.

Further, another embodiment of the sliding door moving mechanism according to the present invention will be described.

As another embodiment of the sliding door moving mechanism according to the present invention, FIG. 8 shows a basic mode. The sliding door moving mechanism shown in FIG. It is assumed that it is built in the audio device A.
FIG. 8 is a rear sectional view showing the internal structure of the sliding door moving mechanism from the rear as another embodiment of the present invention.

The two guide grooves 51 and 52 are obliquely shifted to the upper left with a constant parallel interval P. And are arranged on the lower right. In addition, each of the guide grooves 51 and 52 has a bent end portion 51A or 52A which is bent slightly downward at an outer end portion as viewed as a whole. These bent end portions 51A and 52A are also provided on the swing arms 31 and 3 respectively.
In order to match the trajectory drawn by the crank pins 31B and 32B when the 2 rotates, it is partially curved with a curvature radius substantially equal to the rotation radius of the swing arms 31 and 32. As a result, the crankpins 31B and 32B are bent at the end bent portions 51.
A and 52A, the sliding door 1
Even if an external force is applied to the slider frame 20, the slider frame 20 does not move up and down.

The two swing arms 31 and 32 are substantially the same as those in the previous embodiment, but each of the base ends 31C and 32
The straight line L1 connecting the rotation centers 31D and 32D of C is the guide groove 5
It is arranged so as to be deviated toward the upper left and lower right so as to form an acute angle with the straight line L2 parallel to 1,52.

The drive system 60 partially corresponds to the previous embodiment, but includes arm gears 61 and 62 formed on the outer periphery of the base ends 31C and 32 of the swing arms 31 and 32, and these arm gears 61 and 62. Are connected to each other to rotate in opposite directions; two synchronous gears 63 and 64; a drive motor M that is rotatable in both forward and reverse directions to generate a rotational drive force; It is composed of a belt 45 as a reduction gear train to be transmitted to the arm gear 61, a pulley gear 46, two reduction gears 47 and 48, and the like. More specifically, in the drive system 60, when the drive motor M rotates counterclockwise, the pulley gear 46 also rotates counterclockwise via the belt 45, and the reduction gear 47 meshing with the pulley gear 46 And the other reduction gear 48 meshing with the reduction gear 47 rotates counterclockwise, and the reduction gear 48 meshes with the left arm gear 61, whereby the left swing arm 32 rotates clockwise. I do. At the same time, the left synchronization gear 63 meshing with the arm gear 61 rotates counterclockwise, the right synchronization gear 64 meshing with the synchronization gear 63 rotates clockwise, and the synchronization gear 64 and the right arm gear 62 Are designed so that the right swing arm 32 rotates counterclockwise by meshing with each other.

Note that a series of movements in other embodiments are almost the same as those in the previous embodiment except that the rotation direction of the drive motor M is reversed. 1 shows the operation state, and the description thereof will be omitted.

Therefore, according to the sliding door moving mechanism according to another embodiment, the two swing arms 31 and 32 can be rotated without interfering with each other, as clearly shown in FIGS. The same effect as in the above embodiment can be obtained.

In particular, as shown in FIG.

Regarding 32D, distance C1 between centers separated along the left-right direction
Is shorter than the center-to-center distance C shown in FIG. 7 in the previous embodiment, so that the internal space can be trimmed in the left-right direction to reduce the size of the housing 12, thereby further reducing the size of the entire audio device A. It can be achieved even more.

The present invention is not limited to the above embodiments.

The audio device A is not limited to a CD player, but may be a player such as a DVD or MD.
