BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvement of a door lock structure in a housing of electronic equipment.

[0002]

2. Description of the Related Art FIGS. 12 to 14 show a door lock structure in a conventional electronic equipment casing.

As shown in FIG. 12, this type of casing includes a casing body 1 for housing electronic equipment (not shown) and a door 3 rotatably attached to the casing body 1 via a hinge 2. The opening 1a of the housing body 1 is closed by the door 3 by rotating the door 3 in the direction of arrow a, and the opening 1a is opened by rotating the door 3 in the direction of arrow b. . When the door 3 is closed, the upper and lower parts of the door 3 are locked to the housing body 1 by the following lock mechanism,
When the handle 5 provided on the front surface of the door 3 is rotated in a predetermined direction, the door 3 is unlocked. This lock structure is configured as follows.

As shown in FIG. 13, a plate 6 which rotates integrally with the handle 5 is attached to the back side of the door 3, and the lower end side of the first rod 7 rotates on the upper end side of the plate 6. It is freely connected. The lower end of the second rod 8 is rotatably connected to the upper end of the first rod 7. The second rod 8 is supported by a guide fitting 9 fixed to the back surface of the door 3 so as to be slidable only in the vertical direction, and is urged upward by a spring 10. Further, a lock portion 11 having a claw formed upward is provided on the upper end portion of the second rod 8, and when the second rod 8 slides upward with the door 3 closed, as shown in FIG. As shown in a), the lock portion 11 engages with the locking portion 12 provided on the upper portion of the housing body 1, and the rotation of the door 3 in the direction of the arrow b causes the lock portion 11 to contact the locking portion 12. Will be blocked by. Similarly to the upper end side, the lower end side of the plate 6 is also provided with the first rod 7, the second rod 8, the guide fitting 9, the spring 10 and the lock portion 11, and the second rod 8 is moved downward. By sliding to
The lock portion 11 engages with the locking portion 12 provided on the lower portion of the housing body 1.

In the above lock structure, when the door 3 is closed, the upper lock portion 11 automatically engages with the upper lock portion 12 by the action of the spring 10, and the lower lock portion 11 engages with the lower lock portion. The door 3 is automatically engaged with the stopper 12, and the door 3 is locked to the housing body 1 at the upper and lower portions thereof. Further, when the door 3 is opened, when the handle 5 is rotated in a predetermined direction, the plate 6 that rotates integrally with the handle 5 and the second rod 7 on the upper side are operated by the action of the first rod 7 that interlocks with the plate 6. Since the rod 8 slides downward and the second rod on the lower side slides upward, as shown in FIG. 14B, the upper and lower lock portions 11 and 12 are disengaged from each other, and the door is closed. Three
Can be opened.

However, in the above lock structure, since the rotation of the handle 5 is converted into the linear motion of the lock portion 11 by using the first rod 7, it is necessary to make the rod 7 thick to increase the bending strength. Further, in order to smoothly convert the rotation of the handle 5 into the linear movement of the lock portion 11 via the rod 7, the rod 7 needs to be sufficiently long.
Therefore, there is a problem that the rod 7 becomes large and heavy. On the other hand, it is necessary to provide a sufficient space on the door 3 side so as not to hinder the movement of the rod 7, and the door 3 has a strength capable of supporting the lock mechanism including the rod 7.
Since it is necessary to carry it, the door 3 is heavy and large, and thus it is difficult to reduce the size and weight of the housing.

Further, since the door 3 is locked by engaging the locking portion 11 with the locking portion 12, the gap t between the locking portion 11 and the locking portion 12 shown in FIG. There is a problem in that the door 3 rattles when is too large and the lock becomes difficult when the gap t is too small. Therefore, the dimensional accuracy and the assembly accuracy of the lock mechanism need to be made extremely high, resulting in high manufacturing cost of the housing.

[0008]

As described above, in the above-mentioned lock structure, there is a problem that the manufacturing cost of the housing increases because it is necessary to increase the dimensional accuracy of the lock position. Further, the rod for converting the rotational movement of the handle into the linear movement of the lock portion becomes large and heavy, and it is necessary to form a sufficient space in the housing so as not to hinder the movement of the rod. There was a problem that was heavy and large.

The present invention has been made to solve the above-mentioned conventional drawbacks, and the dimensional accuracy of the lock position is not required as much as the conventional one, and the size and weight of the housing can be reduced. The purpose is to provide a locking structure for the.

As shown in FIG. 1, the housing of the electronic apparatus of this embodiment is rotatably attached to the housing body 21 via a housing body 21 for housing the electronic equipment (not shown) and a hinge 22. The opening 21d of the housing body 21 is closed by the door 23 by rotating the door 23 in the direction of arrow c, and the opening 21d is rotated by rotating the door 23 in the direction of arrow d. It will be open. When the door 23 is closed, the upper and lower parts of the door 23 are locked by the housing body 21 by the lock mechanism described below, and when the handle 25 provided on the front surface of the door 23 is rotated in a predetermined direction, the door 23 is closed. Is unlocked. The lock structure of the door 23 has the following structure.

The handle 25 is attached to the front surface of the door 23 so as to be rotatable about the support shaft 25a in the direction of arrow ef, and the central portion of the plate 26 is provided on the back surface of the door 3 at the support shaft 25a. It is fixed to. Therefore, the handle 25
When the plate is rotated in the direction of arrow e-f, the plate 26
Rotate in the -f direction. As shown in FIG. 5, on the upper end side of the plate 26, the wire 2 serving as a motion transmitting means is provided.
The lower end side of 7 is connected, and the upper end side of the wire 27 is connected to the magnet catch portion 30. Also, plate 2
Similarly to the upper end side, the lower end side of 6 is connected to the upper end side of the wire 27, and the lower end side of the wire 27 is connected to the magnet catch portion 30. Since the lock structure of this example has a vertically symmetrical structure about the support shaft 25a, the lock structure on the upper side will be mainly described below.

As shown in FIG. 2, the magnet catch portion 30 has a guide bracket 31 having a U-shaped cross section, a magnet fixing bracket 32 slidably attached to the guide bracket 31, and a first fixing bracket 32 fixed to the fixing bracket 32. It is composed of a magnet 33 and a spring 34, which are two adsorbents.

The magnet 33 is the flat plate portion 3 of the fixing member 32.
It is fixed to the central portion of 2a by means such as adhesion. Further, tongue pieces 32b, 32b are projected outward to the left and right of the fixing metal fitting 32, and the left and right side plates 31a, 31a of the guide metal fitting 31 are provided with guide holes along the longitudinal direction of the side plate 31a. 31b is formed. The fixing metal fitting 32 is attached to the guide metal fitting 31 by inserting the left and right tongue pieces 32b, 32b into the guide holes 31b, 31b. Therefore, the fixing bracket 32,
Therefore, as shown in FIG. 3, the magnet 33 is guided by the guide fitting 3 in the direction of the arrow gh along the longitudinal direction of the guide fitting 31.
It is slidable with respect to 1.

Further, one end of the spring 34 is provided with a guide fitting 31.
Is hooked on a mounting hole 31d provided on the upper end of the fixing metal fitting 32 and the other end is hooked on a mounting hole 32d provided on the upper side of the fixing metal fitting 32. Therefore, the magnet 33 has a spring 34.
It is in a state of being urged in the direction of arrow g by the pulling force of. A screw hole 32e is provided on the lower side of the fixing metal fitting 32, and the stopper 41 provided on the upper end of the wire 27 is fixed to the fixing metal fitting 32 by a screw 42.

As shown in FIG. 1, the magnet catch portion 30 has an arrow g at the upper and lower portions on the back side of the door 23.
It is fixed by screws or the like so that the −h direction is the vertical direction. Further, in this example, the side frame 21a of the housing body 21 is formed of a magnetic body that attracts a magnet, and the frame 21a constitutes a first attractor that the magnet 33 attracts. Also, the frame 21
By forming the notch 21b in a, the magnet 33
Constitutes a non-adsorption portion that does not adsorb. Therefore, the magnet catching portion 30 on the upper side faces the frame 21a (FIG. 6) when the magnet 33 is positioned at the upper position (first position) with the door 23 closed (see FIG. 6). It is arranged on the door 23 so as to face the notch 21b (FIG. 7) when positioned at the lower position (second position). In the lower magnet catch portion 30, the magnet 33 faces the frame 21a at the lower position and faces the notch 21b at the upper position.

The lower end of the wire 27, whose upper end is connected to the magnet 33 side, is connected to the plate 26 as described above. At the time of this connection, as shown in FIG.
A cylindrical wire fixing base 4 is provided on the upper and lower ends of the plate 26.
5 is rotatably attached, the wire 27 is inserted into the through hole 45a of the wire fixing base 45, and the screw 46 is screwed into the screw hole 45b of the wire fixing base 45, whereby the wire 27 is fixed to the wire. It is crimped to the table 45. Also,
As shown in FIG. 5, the wire 27 has a length of the magnet 3
When 0 is in the upper position, the plate 26 becomes vertical, and when the plate 26 is rotated 90 ° in the direction of arrow f,
The tension of the wire 27 allows the magnet 33 to be positioned at a lower position.

Further, as shown in FIG. 5A, when the magnet 30 is at the upper position, the wire 27 is arranged on the extension line of the magnet 33 in the sliding direction (vertical direction). The roller 48 positioned so that the peripheral surface is in contact with the middle of the wire 27 is the door 23.
It is rotatably attached to. Therefore, FIG.
When the handle 25 (and thus the plate 26) is rotated in the direction shown by arrow f in the state shown in FIG. 5, the wire 27 pulls the magnet 33 downward while the wire 27 bends at the roller 48.

By thus sliding the magnet 33 while bending the wire 27, the wire 27
The stroke S of the magnet 33 when the length L is constant can be made larger than that when the wire 27 is not bent, and the lock mechanism can be downsized. Further, by bending the wire 27 with the roller 48,
It is possible to pull the magnet 33 in parallel with the sliding direction of the magnet 33 using the wire 27.
Therefore, since the force other than the vertical direction is not applied to the magnet fixing metal fitting 32, the movement thereof becomes smooth, and the extra force such as the twist is not applied to the guide metal fitting 31. Therefore, it is necessary to increase the strength extremely. Absent. Further, the strength of the door 23 itself to which the guide fitting 31 is attached can be smaller than that of the conventional rod type. In the case of the conventional rod type, it is necessary to secure a sufficient space around the rod 7 so that the rod 7 does not get caught on the back surface of the door 3 or the protrusion. In this case, since it is assumed that the door 23 is bent, there is no problem even if the door 23 has some protrusion. Therefore, wire 27
Since it can be placed close to the back surface of the housing, the overall size of the housing can be reduced.

Next, the operation of the lock mechanism will be described. In the following description, the movement of the magnet 33 on the upper side will be described, but the magnet 33 on the lower side moves upside down.

When no external force is applied to the handle 25, as shown in FIG. 5A, the magnet 33 is in the upper position which is the first position by the action of the spring 34. Therefore, when the door 23 is closed,
As shown in FIG. 6, the magnet 33 is attached to the housing frame 21.
It is magnetically attracted to a and the door 23 is locked to the housing body 21. In this case, since the door 23 is locked by magnetic force, even if there is some variation in the mounting position of the magnet 33 in the rotation direction of the door 23 when the door 23 is closed, the door 23 is reliably locked. There is no rattling.

When the door 23 is opened, the handle 25 is moved in the direction of arrow f.
Rotate in the direction. With this, as shown in FIG. 5B, the magnet 33 is positioned at the lower position which is the second position. Therefore, as shown in FIG. 7, since the magnet 33 faces the notch 21b of the frame 21a, the lock by the magnetic force of the magnet 33 is released. In this unlocking process, the magnet 33
Is slid downward in a direction orthogonal to the acting direction of the magnetic force (the rotating direction of the door 23). Therefore, a small force is applied to the handle 25 when unlocking.

On the other hand, when the door 23 is opened and the hand is released from the handle 25, the magnet 34 is returned to the first position by the action of the spring 34, and the plate 26 is moved to the arrow e shown in FIG.
Is rotated through the wire 27, but the spring 34
The elastic force of is much thinner and lighter than the conventional rod 7,
Moreover, since it is transmitted to the plate 26 via the wire 27 having a low friction, the plate 26 (hence, the handle 25)
Smoothly returns to its original position.

In the lock mechanism described above, the magnetic frame 21a is used as the first adsorbent and the magnet 33 is used as the second adsorbent. However, the first adsorbent is the magnet and the second adsorbent is the magnet. It may be a magnetic body, and the first and second adsorbents may be magnets having different polarities. Although the magnet 33 is configured to face the notch 21b when the magnet 33 is positioned at the second position, a nonmagnetic aluminum plate, a resin plate, or the like may be provided at the notch 21b. Alternatively, a magnet having the same polarity as that of the magnet 33 may be provided in the notch 21b so that the magnetic repulsive force acts in the direction in which the door 23 opens.

Further, in the above embodiment, the wire is used as the motion transmitting means for converting the rotation of the handle 25 into the slide of the magnet 33, but the motion transmitting means in the magnet type locking means is not limited to the wire. A conventional rod may be used instead of one. Further, the handle may be a slide type.

8 to 10 are views showing a second embodiment. FIG. 8 is an exploded perspective view of a rotary magnet catch portion, FIG. 9 is a sectional view of the magnet catch portion, and FIG. It is a figure which shows adsorption | suction and its cancellation | release.

The lock structure of this embodiment shows a case where a rotary magnet catch portion 50 is used in place of the magnet catch portion 30 of the first embodiment.

The magnet catch portion 50, as shown in FIGS. 8 and 9, is a pedestal 5 erected on the back side of the door 23.
1. Coil-shaped spring 5 attached to this pedestal 51
2, a rotating plate 53 rotatably attached to the pedestal 51,
The rotary plate 53 is composed of a ring-shaped magnet 54 and the like.

The magnet 54, as shown in FIG.
The north pole and the south pole are alternately arranged at equal intervals and are fixed to the rotating plate 53 by adhesion. Spring 52
Is the door 23 at the one end 52a side with the pedestal 51 inserted.
Is hooked on the hole 61 formed in the. Magnet 54
Hole 53a provided at the center of the rotary plate 53 to which the
A spacer 56 is inserted into the rotary plate 53 and the spacer 56 is fixed to the pedestal 51 with a screw 57.
Is attached to the base 51. Therefore, the rotating plate 53
(Thus, the magnet 54) can rotate about the spacer 56 in the direction of arrow gh shown in FIG. Also,
Two hole portions 53b and 53c are formed in the peripheral portion of the rotary plate 53 at positions symmetrical with respect to each other, and the other end 52b of the spring 52 is hooked in the hole portion 53b. Therefore, the magnet 54 is maintained at a predetermined position (first position) by the elastic force of the spring 52. Further, the other end of the wire 63 whose one end is connected to the handle 25 side is connected to the hole 53c by a screw 64. Therefore, when the handle 25 is rotated, the magnet 54 is rotated a predetermined angle from the first position in the direction of arrow g shown in FIG.
When the external force is removed from the handle 25, the spring 52 rotates in the direction of arrow h to return to the first position.

On the other hand, the magnet 5 is provided on the housing body 21 side.
A magnet 65 having the same shape and the same configuration as that of No. 4 is fixed. The magnet 65 is arranged so as to face the magnet 54 when the door 23 is closed, and when the magnet 54 is at the first position, the magnet 5 is disposed.
When the magnets 4 and the magnet 65 have different polarities facing each other and the magnet 54 is at the second position, the magnets 54 and 65 have the same polarities facing each other.

With such a structure, when the handle 25 is not subjected to an external force, the spring 5
By the action of 2, the magnet (second adsorbent) 54 is moved to the first
10 (a) when the door 23 is closed and the door 23 is closed.
As shown in FIG. 3, the different magnets of the magnet 54 and the magnet (first adsorbent) 65 are attracted to each other, and the door 23 is attached to the housing body 21.
Locked in. When opening the door 23, the handle 25 is rotated in a predetermined direction. As a result, FIG.
The magnet 54 is positioned in the second position, as shown in FIG. Therefore, the lock due to the attractive force of the magnet is released, and the repulsive force due to the same poles acts, and the door 2
3 receives the force by the magnetic force of the magnet in the opening direction.
Since the direction of rotational movement of the magnet 54 is perpendicular to the attraction force, the handle 2 is released when the lock is released.
As in the first embodiment, the force applied to 5 is small.

FIG. 11 is a diagram showing a third embodiment. This example does not solve the problem of making the housing smaller and lighter than the conventional problems. That is, the door 23 is provided with the same lock portion 71 as that of the conventional example.
The rod 72 having the end 1 attached thereto is slidably supported only in the vertical direction by a guide metal fitting 73 fixed to the door 23. Further, the lock portion 71 is biased upward by the spring 75. On the other hand, a locking portion 77 that engages with the lock portion 71 is provided on the housing body 21 side. However, as the motion transmitting means for transmitting the rotation of the handle 25 to the lock portion 71, the wire 2 is used instead of the conventional rod.
7 is used. The wire 27 is connected between the plate 26 and the rod 72 in the same structure as in the first embodiment, and, like the first embodiment, the wire 27 is bent in the middle of the door 23. Rollers 48 are provided.

Also in this example, when no external force is applied to the handle 25, the lock portion 71 is positioned at the first position shown in FIGS. When the lock is closed,
The door 23 is locked to the housing body 21 by engaging with 7. When the handle 25 is rotated in a predetermined direction, the wire 27
Thus, the lock portion 71 is pulled and positioned at the second position shown in FIG. 11 (c). Therefore, the engagement state between the lock portion 71 and the locking portion 77 is released, and the door 23 can be opened.

In this embodiment, since the bendable wire 27 having a small diameter is used instead of the conventional rod having a large diameter, the lock mechanism and the entire housing are made smaller as in the first embodiment. The weight can be reduced. Further, since the roller 48 is provided, the rod 72 can move the wire 27 only in the sliding direction.
Since it receives the tension of, the twisting force does not act. Therefore,
The guide metal fitting 73 that supports the rod 72 may be smaller and lighter than the conventional guide metal fitting 9.

As described above, in the invention according to claim 1, the second adsorbent provided on the door and the first adsorbent provided on the housing body are magnetically attracted to each other. Since the door is configured to be locked to the main body of the housing, the accuracy of the mounting positions of the first and second suction bodies can be made gentler than in the case where the door is locked by mechanical engagement. Therefore, the processing cost and the assembly cost of the parts can be reduced. Also, the first
Also, since the lock is released by sliding the second adsorbent in the direction substantially orthogonal to the adsorbing direction of the second adsorbent, the force applied to the handle at the time of unlocking is small.

Therefore, the effect of claim 1 In addition, there is an effect that the second adsorbent can be easily attached to the door.

In the invention according to claim 4, since the second adsorbing member is moved by using the wire of the rotation of the handle as the transmitting means, the motion transmitting means is small in size in addition to the effects of the first to third aspects. It has the effect that it can be converted into a small space.

In the invention according to claim 5, the rotation of the handle is converted into the linear movement of the second adsorbent by using the wire as the transmission means, and further, the second adsorbent is moved by the wire bent by the roller. In addition to the effect of claim 1, in addition to the effect of claim 1, the motion transmitting means for converting the rotary motion into the linear motion can be miniaturized to save space, and the second adsorbent can be supported. It has the effect of facilitating.
