DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, the present invention will be described based on embodiments shown in the drawings. FIG. 1 is a perspective view of the disk insertion / extraction device according to the first embodiment. 1 is a housing (chassis), 2 is a disk device, 3 is a front projection, 4 is a rear projection, 5 is a front projection, 6 is a rear projection, 7 is an upper beam, 8 is the lower beam, 9
Is a connector (female) on the housing side, 10 is a connector (male) on the disk device side, 11 is a square hole, 12 is a stopper, 13 is a tray, 14 is a back panel, 15
Is a fixing screw.

The housing 1 is configured to house a removable disk device 2 as a part of an electronic apparatus (for example, a server computer). Storage body 1
Has a back panel 14 on the back, and the back panel 14
Is provided with a connector 9 for electrical connection with the disk device 2.

A beam 7 is provided on the upper surface, and a beam 8 is provided on the lower surface. The beam 7 and the beam 8 form a pair and have a function of guiding the protrusions 3 to 6 attached to the disk device 2 and a function of pressing the protrusions 3 to 6 to fix the disk device 2. I have. In many cases, a plurality of disk devices 2 can be mounted according to the demand for expandability and maintainability of the electronic device. However, the present invention is effective even when a single disk device 2 is mounted.

FIG. 2 is a plan view of the storage section according to the first embodiment. As shown in the figure, the width of the beam 7 as a guide decreases in the insertion direction. Thereby, the pushed-in protrusion can be pressed from both sides.

FIG. 3 is a side sectional view of the disk insertion / extraction device according to the first embodiment. As shown in the figure, the beam 7 is inclined so as to protrude inside the storage section 1 in the insertion direction. Thus, in the mounted state, the protrusions 3 and 4 can be pressed inward with respect to the swing direction (vertical direction in this figure). The same applies to the relationship between the beam 8 and the projections 5 and 6. The beam 7 is generated by cutting out the upper surface of the chassis, which is usually the storage body 1, and performing plastic working by pressing, so that the production cost can be kept low. Further, it is configured using a material having elasticity. Therefore, the smaller the inclination of the protrusion that protrudes into the storage unit 1, the greater the force that presses the protrusion.

FIG. 4 is a front sectional view of the disk insertion / extraction device according to the first embodiment. As shown in the figure, the beam 7 and the beam 8 face each other, and apply pressure to the near-side protrusion 3 and the near-side protrusion 5, respectively.

Next, the disk device 2 will be described.
The disk device 2 is electrically connected to an electronic device. Therefore, there is a connector 10 that is gripped by the connector 9 and connects the conductors.

In addition, the disc device 2 is fixed to the tray 13 so that the operator can perform the insertion / removal operation at the time of insertion / removal. Further, projections 3 to 6 for holding the disk device 2 in the housing 1 in the mounted state are attached.

FIG. 5 is an instruction diagram for mounting the tray and the projection in the first embodiment. The disk device 2 is provided with screw holes 16 to 18 for attachment in advance. The tray 13 is fixed to the screw hole 16 using the fixing screw 15 as shown in the figure. In addition, the near side projection 3
The rear projection 4 is attached to the screw hole 17,
Attached to. Similarly, the front projection 5 and the rear projection 6 are attached to the opposite surface.

Further, the disk insertion / extraction device is provided with a removal prevention unit. In this example, a square hole 11 provided in the storage body 1 and a stopper 12 provided in the tray 13
(Projections). A recess may be used instead of the square hole 11. The stopper 12 is configured to hook on the square hole 11 or the concave portion in the inserted state. Thereby, it is possible to prevent the disk device 2 from slipping out. Contrary to this example, a hole or a concave portion is provided in the tray 13, a convex portion is provided in the housing 1, and the convex portion of the housing 1 is
The same effect can be obtained even if the tray 13 is hooked on a hole or a recess. Further, the detachment prevention portion is not limited to these configurations, and the storage body 1 may be relatively positioned in the inserted state.
It is effective as long as it resists the force in the direction in which the disk device 2 comes out of the disk drive.

The operation of inserting the disk device 2 will be described. The operator holds the handle portion of the tray 13 and first puts the rear projection 4 inside the beam 7, and similarly puts the rear projection 6 inside the beam 8.

In this state, the back projection 4 and the back projection 6 are arranged along the beam 7 and the beam 8, and the disk device 2 is pushed toward the back of the housing 1.

The smaller the inclination of the protrusion protruding into the storage part 1, the greater the force of the beam 7 pressing the projection in the swinging direction. Therefore, the resistance force associated with the insertion is small in the initial stage of the insertion. Therefore, in the initial stage, it is easy to perform the operation of following the guide. In other words, the operation of following the guide can be easily started even from a slightly twisted state or a laterally displaced state, and the range of the trajectory that can be normally inserted is widened. Further, the resistance generated when the guide is removed and inserted is easily recognized as a sense of incongruity that does not occur in a normal state. This facilitates the insertion operation. In addition, the work at the time of extracting becomes easy.

In the final stage, the connector 10 is
Is engaged and gripped. At the same time, the stopper 12 enters the square hole 11 and is caught. Thereby, the insertion operation is completed. At this time, the projections 3 to 6 serve to hold the disk device 2 inside the housing 1.

When the disk device 2 is operated in this state, the disk device 2 swings up and down around the joint between the connector 9 and the connector 10 with the operation inside the disk device 2.

FIG. 6 is an enlarged side view of the pressure contact portion in the first embodiment. In the plane shown, pressures 21 and 22 are applied to the front projection 3 and the rear projection 4 by the beam 7. As shown in the figure, when the beam 7 is inclined inside the storage body 1, the pressure 2
1 and 22 are generated by tilting forward. Therefore, in addition to the vertical component forces 23 and 25 applied to suppress the swing, component components 24 and 26 in the pushing direction are applied. Therefore, there is a problem that the disk device gradually comes out due to its own swing and the electrical connection of the connector portion cannot be maintained. However, in the present invention, such a problem is prevented because the disk device has the removal prevention portion. it can.

FIG. 7 is an enlarged front view of the press contact portion in the first embodiment. In the plane shown, the beam 7 is exerting pressure on the front projection 3. Assuming that the curvature of the beam 7 and that of the near side projection 3 are the same, the two contact linearly, and pressure is applied to each point on the line.

For example, near the contact point where the inclination of the tangent is 45 degrees, a pressure 31 is applied. This pressure 31
Is divided into a partial pressure 32 in the vertical direction and a partial pressure 33 in the horizontal direction. The partial pressure 32 is a component applied to suppress the swing, but the partial pressure 33 is a force that suppresses the near-side protrusion 3 toward the center line. Since such a force is applied to the left and right objects, the force is applied from both sides. Further, when the front side protrusion 3 is shifted laterally, the magnitude of the partial pressure in the direction of returning the shift is increased, and the effect of returning to the original position is effected. As described above, the vertical partial pressure 32 generates a component force that presses the protrusion inward with respect to the swing direction, and the horizontal partial pressure 33 presses the protrusion from both sides inward in the disk rotation axis direction. Create a component force.

In particular, the component force that presses the protrusions from both sides inward in the direction of the disk rotation axis can prevent longitudinal twisting and lateral displacement caused by the operation of the disk device. Thereby, the physical load on the connector can be reduced.

Near the tangent where the inclination of the tangent is 90 degrees, no vertical force is applied from the beam 7 except for the frictional force. However, since the width as the guide is equal to the width of the front side projection 3, when a force to shift the front side projection 3 to the side acts, a drag is generated. Therefore, a force for returning to a small displacement is generated.

Since the above-mentioned pull-out preventing portion generates a resistance against a force in a direction in which the disk device comes out, it is possible to apply a high pressure from the beam, and it is possible to further stabilize the disk device. At this time, not only the swing direction but also the partial pressure in the direction of the rotation axis of the disk can be increased, and the prevention of twisting and the like can be ensured.

Embodiment 2 In the above-described embodiment, an example has been described in which the beam has a semicircular cross-section, and the protrusion has a hemispherical head whose curvature is adapted to have a continuous semicircular contact with the beam. . In the present embodiment, various beam shapes and protrusion shapes will be described, and further, an operation when they are combined will be described.

FIG. 8 is a diagram showing a beam shape. The front view and side view of each beam are shown. Reference numeral 41 has a semicircular cross section similarly to the beam used in the above-described embodiment. Reference numeral 42 has a cross section composed of two sides excluding the base of the triangle. Reference numeral 43 has a cross section including three sides excluding the base of the trapezoid.

Each beam is common in that it is inclined inside the housing and the width as a guide is tapered. However, even if the taper is not tapered, the disk device can be fixed and effective if the protrusion does not shift laterally in the mounted state.

FIG. 9 is a diagram showing the shape of the projection. Each projection is a rotating body. Also, a fixing screw is provided at the lower part. 51 and 52 have hemispherical heads, and 53 has a planar head. 51 has a vertical side surface;
And 53 have hakama-shaped side faces with widened hem. These projections are examples, and may be other than a rotating body. Further, the shape of the head is not limited to these examples.

Next, these combinations will be described.
An example is shown in the figure. FIG. 10 is a diagram illustrating a first example of a combination of a beam and a protrusion according to the second embodiment. FIG.
FIG. 19 is a diagram showing a second example of a combination of a beam and a protrusion in the second embodiment. In these examples, the protrusion receives inwardly inclined pressure from the side portion of the inwardly inclined beam. Therefore, a vertical component force and a horizontal component force are received, and the same operation and effect as in the first embodiment can be obtained.

When the height of the projection is different, the displacement of the beam is different and the applied pressure is also different. Therefore, the pressure can be adjusted by the height of the projection. The partial pressure in the direction of sandwiching from both sides can also be adjusted.

Embodiment 3 An embodiment in which a guide facing the insertion direction is provided on the surface of the storage unit facing the beam will be described.

FIG. 12 is a front sectional view of the disk insertion / extraction device according to the third embodiment. The composition of the guide is
The configuration may be the same as that of a conventional guide. The guide has no elasticity and does not displace when subjected to pressure.

Since the guides are provided on the opposing surfaces in the storage section 1, the disk device is fixed at at least three points. Therefore, it is possible to withstand the positive and negative rotational moments in the disk plane, and it is possible to reduce the physical load on the connector. Further, since the guide is not displaced by the pressure from the disk device caused by the pressure of the beam, the position of the connector 10 of the disk device can be specified with reference to the guide, and the connectors 9, 10 in the joining can be specified.
The accuracy of the positional relationship between them can be improved.

Embodiment 4 The storage body, as a beam,
An embodiment having a back beam that presses the back projection and a front beam that presses the front projection will be described.

FIG. 13 is a plan view of the storage section according to the fourth embodiment. FIG. 14 is a cross-sectional view in the side direction of the storage unit according to the fourth embodiment.

The disk device 2 to be mounted, the tray 13,
The projections 3 to 6 are the same as in the first embodiment. When the disk device 2 is mounted, the rear beam 16 on the rear side of the storage unit 1 presses the rear projection 4, and the manual beam 17 on the front side of the storage unit 1 presses the front projection 3. I do.

When two projections are fixed by one beam, if one pressure increases due to a shape error, the other pressure decreases and influences each other. However, in the present embodiment, the rear side projection and the front side projection are provided, and pressure is applied by separate beams. Therefore, compared to the case of pressing by the same beam, the pressure of the projection or the beam due to the shape error of the beam is reduced. The error is reduced.

In the above example, the case where the disk device is mounted vertically has been described. However, the present invention is effective even when the disk device is mounted horizontally.

[0058]

According to the present invention, since the projection mounted so as to protrude in the swinging direction is pressed by the beam also serving as a guide, the disk device can be brought into close contact with the storage portion with a simple structure. To eliminate the influence of the swing on the disk device.

[0059] Due to the elasticity of the beam, the smaller the inclination that protrudes into the storage portion, the greater the force that presses the protrusion in the swinging direction. Therefore, the resistance force accompanying insertion increases in the final stage of insertion. , Small in the early stages of insertion. Therefore, in the initial stage, it is easy to perform an operation of following the guide, and it is easy to recognize the resistance generated when the guide is removed and inserted as a sense of incongruity that does not normally occur. For this reason, an erroneous insertion operation deviating from a normal trajectory can be prevented. Also, the pressure can be adjusted by changing the height of the projection.

Further, since the beam has a surface for generating a component force for pressing the protrusion inward in the direction of the disk rotation axis from both sides, it is possible to prevent the disk device from being twisted or laterally displaced. The swing is particularly effective when a rotational moment is generated in the disk device about the longitudinal direction, or when the center of gravity moves in the rotational axis direction. Preventing small movements such as twisting and lateral displacement stabilizes the operation of the disk device, reduces the load on the connector, and stabilizes the electrical connection. Furthermore, it helps to simplify the configuration of the connector.

Since the beam has a semicircular cross section, it can generate the above-mentioned component force to be pressed from both sides.

Since the beam has a cross section consisting of two sides excluding the base of the triangle, it is possible to generate the above-described component force for pressing from both sides.

Since the beam has a cross-section consisting of three sides excluding the base of the trapezoid, the above-mentioned component force can be generated to apply pressure from both sides.

The force of pressing the projection in the swinging direction increases as the inclination of the projection extending into the storage portion decreases due to the elasticity of the beam. Therefore, the component force for pressing the projection from both sides also increases in the final stage of insertion. No, small in the early stages of insertion. Therefore, in the initial stage, the operation of easily following the guide can be started even from a slightly twisted state or a laterally displaced state, and can be fixed at a predetermined position in the final stage. As described above, the range of the track that can be normally inserted is widened, and the insertion operation is facilitated. In addition, the work at the time of extracting becomes easy. Further, by changing the height of the projection, the pressure in the direction of the rotation axis of the disk can be adjusted.

When the beam is inclined inward in the mounted state, the beam generates a component force in the direction of pushing the disk device. For this reason, the disk device gradually comes out with the swing of the disk device itself, which may cause a problem that the electrical connection of the connector portion cannot be maintained. In the present invention, such a problem can be prevented because of the removal prevention portion.

Further, since the pull-out preventing portion generates a resistance against the force in the direction of pulling out, it is possible to apply a higher pressure to the beam, and it is possible to further stabilize the disk device. At this time, not only the swing direction but also the partial pressure in the rotation axis direction can be increased, and the prevention of twisting and the like can be ensured.

Further, since the convex portion attached to the disk device is engaged with the concave portion or the hole provided in a part of the storage portion, the above-described drag can be generated.

Further, since the concave portion or the hole portion attached to the disk device is engaged with the convex portion provided in a part of the storage portion, the above-described drag can be generated.

Since the projection is fixed to a mounting hole provided for mounting in advance, the disk device can be stabilized according to its characteristics. In addition, since the interval between the beam and the disk is short, the effect of shaking due to expansion and contraction or deformation of the holding unit itself does not occur.

The width of the beam as a guide becomes narrower in the insertion direction, and the projection presses the projection from both sides in the rotation axis direction in the mounted state. Accordingly, it is possible to prevent the disk device from being twisted or shifted laterally.

Since the rear projection and the front projection are provided, the swing can be stopped with a larger force.

Since a similar beam is provided on the opposing surfaces in the storage section, the disk device can be fixed at four points. Therefore, it is possible to withstand the positive and negative rotational moments in the disk plane, and it is possible to reduce the physical load on the connector.

Since similar guides are provided on opposing surfaces in the storage section, the disk device is fixed at at least three points. Therefore, it is possible to withstand the positive and negative rotational moments in the disk plane, and it is possible to reduce the physical load on the connector. Further, since the guide is not displaced by the pressure from the disk device caused by the pressure of the beam, the connector position of the disk device can be specified with reference to the guide, and the accuracy of the positional relationship between the connectors in joining can be improved.

Since the rear side projection and the front side projection are provided and pressure is applied by separate beams, the pressure error caused by the shape error of the projections and the beam is reduced as compared with the case where the same beam is pressed.
