Abstract

PURPOSE:To lighten the shock to other equipment accommodated in the same casing by providing a shock absorbing member, which lightens the insertion force on and after the set point when inserting a device along a guide, a lever, and a stress direction converting means, which converts the force in vertical direction of a lever into the force in direction of insertion and extraction after the shock absorbing means starts operation. CONSTITUTION:As a disk unit case 1 is pushed into an accommodation case (casing), holding a handle 12, a mobile pin 15 hits against the shock absorbing member 8 attached to a guide plate 9, and lock comes off. Since the ratio of the push-down distance of the handle to the push-in distance can be set freely by changing the set angle of the inclination of the guide groove of the guide plate 9, the speed or the strength of engagement can be added or reduced by adding or reducing the speed or the strength of the press-down of the handle 12. Moreover, the push-in force is lightened by its hitting on the shock absorbing member 8, the shock given to other disk units is lightened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for accommodating a heavy device such as an electronic device in a casing along with a guide and inserting or removing it into or from a predetermined plug or the like.

[0002]

2. Description of the Related Art Conventionally, as a mechanism for accommodating a disc unit accommodating an electronic device such as a disc device in a casing along with a guide, and inserting or removing the disc unit into or from a predetermined connector, etc.
There is a structure shown in. In the figure, 1 is a disk unit case in which a disk device is housed, 2 is a handle attached to the disk unit case, and 3 is its set screw. Reference numeral 4 is a housing case for housing the disk unit, and 5 is a guide rail for positioning at the time of housing and guiding it so as to be properly fitted to a plug provided at the rear portion of the housing case 4. The housing case 4 is provided with a vent hole 6 for radiating heat.

The operation of connecting the disk unit to the connector by the conventional mechanism is as follows. First, the disk unit case 1 is placed on the housing case 4, and the guide rail
Push it along the cable 5, and finally hold the handle 2 and push it in to insert it into the stopper. When removing the disk unit from the plug, perform the reverse operation.

For insertion and removal of a printed circuit board or the like, instead of a heavy disk unit, levers are provided at both ends of the circuit board, and the levers are provided so that the levers are moved in a prying principle. There is a method of removing the substrate from the plug, but this is only a mechanism for amplifying the removal force.

[0005]

Since the conventional device insertion / removal mechanism is constructed as described above, by inserting / removing the device, another device, such as a disk unit, housed in the same housing is impacted. However, there is a problem in that a seek error or a lead error is caused to cause a malfunction of the disk unit.

The present invention has been made to solve the above-mentioned problems, and it softens the impact of the connection between the device to be housed and the housing, and adjusts the depth and speed of the splice connection. The purpose of the present invention is to obtain a device insertion / extraction mechanism in which the impact is further reduced.

[0007]

An apparatus insertion / removal mechanism according to the present invention includes a cushioning means for absorbing the insertion force after a set point in the insertion direction to reduce the insertion force when the apparatus is inserted along a guide. And a stress direction changing means for converting the force of the lever in the vertical direction into a force in the inserting / removing direction after the buffer means starts to operate.

[0008]

In the device insertion / removal mechanism according to the present invention, when the device is pushed in along the guide in the housing, the buffer means starts operating at the set point to soften the insertion force, and then the lever.
When, for example, is pushed down, the device moves further into the back and is joined to the stopper. At that time, the joining speed of the plug is determined by the pressing speed of the lever.

EXAMPLES Example 1. FIG. 1 is a structural diagram showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a disk unit case, which is the same as the conventional one, and accommodates a disk device inside. This is stored in the same storage case 4 as the conventional case. 7 is a column in the housing case, and 8 is a rotatable cushioning member, which is made of thick hard rubber. Reference numeral 9 is a guide plate, and a guide groove is cut in the plate. Reference numeral 10 is a recess for stopping the cushioning member, which is fixed to the guide plate 9 by a spring pin fitted in the center of the hard rubber 8. Reference numeral 11 denotes a guide rail, which has the same function as a conventional guide rail. 12
Is a handle, which is not fixed to the disk unit case in this example, and can be rotated downward about a pin 14 described later as a fulcrum when unlocked. 13 is a lot rod, which slides into the guide groove of the guide plate in the process of inserting the device. Reference numeral 14 is a pin for fixing the handle to the disk unit case. Reference numeral 15 is a movable pin that locks the downward pressing of the handle, and 16 is a spring that locks the rotation of the handle by pressing the movable pin 15 into the notch of the lever of the handle.

FIG. 2 is a side view for explaining the locked state of the movable pin. It is the figure which looked at the handle part of FIG. 1 from the side, and the movable pin 15 is pressed by the spring 16 to the notch of the handle 12. FIG. 1 shows a state in which the disk unit case 1 is about to be accommodated in the accommodation case 4. Next, the operation will be described. As shown in FIG. 1, when the movable pin 15 is not in contact with the buffer member 8 attached to the guide plate 9, the movable pin 15 is pressed by the spring 16 into the notch of the lever of the handle 12, 12 does not move downward. In this state, holding the handle 12 and pushing the disk unit case 1 into the storage case 4 (housing), the movable pin 15 is attached to the guide plate 9 as shown by the chain line. It hits the cushioning member 8. After that, the movable pin 15 is pushed in the direction of the arrow in FIG. 2 to unlock. Almost at the same time, the lot rod 13 attached to the lever of the handle 12 enters the take-in groove of the guide plate 9. Still further, when the handle 12 is pushed in, while the cushioning member 8 relieves the pushing force, the movable pin 15 is pushed out of the notch of the lever of the handle,
The handle 12 is unlocked.

The lot rod 13 eventually stops by hitting the end of the groove of the guide plate, and when the handle is pushed down, the lot rod 13 is forced to slide along the guide groove of the guide plate 9. The guide groove of this guide plate 9 is shown in FIG.
As shown in (b), since it is set diagonally, when the handle 12 is pressed and the lot rod 13 slides diagonally downward, the disk unit case 1 is inevitably pushed inward. Be done. By changing the setting angle of the oblique inclination of the guide groove of the guide plate 9, it is possible to freely set the ratio of the pushing distance of the handle and the pushing distance. It can be obtained by pressing. It can be either easily determine this order to fit if the user presses down much, it is possible to moderate the speed or strength of the fitting and adjusting the speed or intensity of the pressing of the handle. Also, the pushing force is softened by hitting the cushioning member, and the impact given to the other disk units is greatly alleviated. In this embodiment, since the handle is locked until the movable pin hits the buffer member, it is easy to remove the disk unit case from the storage case (housing) and carry it.

Example 2. In the above-mentioned embodiment, the ring-shaped thick hard rubber is used as the cushioning member, but a spring such as a leaf spring or a coil spring may be used. Further, in the first embodiment, the cushioning member is attached to the guide plate fixed to the housing side and the movable pin is a rigid body, but the cushioning member may be attached to the movable pin side and the housing side may be a rigid body.

Embodiment 3. In the above embodiment, the guide plate having the guide groove is fixed to the housing side, and the lot rod is provided on the handle or the disk unit case side. However, this is reversed and the lot rod is fixed to the casing side. The guide groove may be provided on the side of the handle or the disk unit case.
Further, the guide groove may be oriented in the upper back direction instead of the lower back direction as shown in the first embodiment, and the handle may be raised and pushed.

Example 4. In Example 1, the force by pushing down the handle was converted into the pushing force in the depth direction by the combination of the lot rod and the guide groove of the guide plate. However, the rack (spur gear) and the pinion (rotating gear) were used to change the radius. Different 2
The same effect can be obtained even if two pinions are concentric with each other, and the racks meshing with each other are arranged such that one is in the handle pressing direction and the other rack is aligned in the depth direction of the housing. In this case, an arbitrary pushing distance can be set by the inclination of the guide groove in the first embodiment, whereas the ratio of the pushing distance and the pushing distance of the handle is determined by the radius ratio of the two pinions.

[0015]

As described above, according to the present invention, when the device is inserted along the guide, the buffering means for cushioning the insertion force after the set point and the lever are provided so that the lever can be operated after the buffering operation starts. Since the device is equipped with a stress direction conversion means that converts the force in the vertical direction into the force in the insertion / removal direction, the device is housed in a housing, and the shock when fitting into a connector etc. is softened and housed in the same housing This has the effect of reducing the influence on other devices.
