Description

  The present invention relates to an improvement of a housing storage rack that stores a housing that stores electronic components.

  A housing for storing electronic components, for example, a tray for mounting a housing for a computer or various control devices, a rack body for storing a tray on which the housing is mounted, and a horizontal guide for the moving direction of the tray However, a housing-accommodating rack having a slide rail that allows a tray pull-out operation and a storage operation to the rack body is already known.

  FIG. 7 is a side sectional view showing a general configuration example of this type of housing housing rack in a state where the tray on which the housing is placed is stored, and FIG. 8 is a diagram showing the tray on which the housing is placed. It is the sectional side view shown in the state pulled out.

  7 and 8 includes a tray 102 for mounting a casing 101 that stores electronic components, a rack body 103 that stores a tray 102 on which the casing 101 is mounted, And a slide rail 104 that allows the tray 102 to be pulled out and stored in the rack body 103 while guiding the moving direction of the tray 102 horizontally.

As shown in FIG. 8, the slide rail 104 includes a fixed side guide rail 104 a fixed inside the side wall 105 of the rack body 103, a movable side guide rail 104 b fixed on both sides of the tray 102, and The floating guide rail 104c is slidably fitted to the fixed guide rail 104a and the movable guide rail 104b.
Therefore, in the state where the tray 102 is stored in the rack body 103 as shown in FIG. 7, the fixed guide rail 104a, the movable guide rail 104b, and the floating guide rail 104c are completely overlapped, and the entire length of the slide rail 104 is reached. In the state in which the tray 102 is completely pulled out from the rack body 103 and the housing 101 can be taken out as shown in FIG. 104b is reliably supported by the fixed guide rail 104a via the floating guide rail 104c, and the posture of the tray 102 can be easily held.

  A caster 106 for supporting a part of the load of the tray 102 and the casing 101 is fixed to the front end on the lower surface of the tray 102, that is, the lower surface on the right end side of the tray 102 shown in FIGS. The tray 102 is pulled out to prevent a change in posture or toppling over when the housing rack 100 becomes a front heavy.

  Further, as shown in FIG. 7, casters 107 are attached to the four corners of the lower surface of the rack body 103 so that the housing accommodating rack 100 housing the housing 101 can be easily moved on the floor. .

  In the example shown in FIG. 7, the two casters 107 attached to the front end on the lower surface of the rack body 103, that is, the lower surface on the right end side of the rack body 103 shown in FIG. The two casters 107 on the side are made to be track-type fixed vehicles so as to allow the housing rack 100 to turn on the floor. However, the arrangement of the track-type universal vehicle and the track-type fixed vehicle may be reversed. .

  Further, in front of the two casters 107 constituted by the truck-type free wheel, that is, at the right end in FIG. 7, the horizontal state of the housing housing rack 100 is secured and the positional displacement of the housing housing rack 100 with respect to the floor is prevented. Therefore, a bolt leg 108 serving both as a level adjusting means and a simple fixing means is attached.

  When storing the housing 101 in the empty housing housing rack 100, first, the housing 101 is placed on the tray 102 as shown in FIG. Then, the tray 102 on which the casing 101 is placed is pushed into the rack body 103, and the tray 102 and the casing 101 are stored inside the rack body 103 as shown in FIG.

Also in the housing housing rack 100, the housing engaging surface 109a of the tray 102 engages with the lower portion of the housing 101 to suppress the displacement of the housing 101 in the horizontal plane. The horizontal displacement of the casing 101 on the tray 102 can be suppressed for the time being, but there is no configuration for suppressing the vertical displacement of the casing 101 on the tray 102. 8, the gap S is formed between the top plate 110 of the casing 101 and the top plate 111 of the rack body 103, so that the upper and lower sides of the casing 101 on the tray 102 are not shown in FIG. Directional misalignment becomes a problem.
Of course, if this gap S does not exist, the vertical displacement of the casing 101 does not occur. However, even if the tray 102 is completely pulled out as shown in FIG. Since a part of the mounting surface 102 a, that is, the left end portion of the housing mounting surface 102 a shown in FIG. 8 remains in the rack main body 103, the top plate 110 of the housing 101 and the top plate of the rack main body 103 are left. If the gap S with the head 111 is eliminated, the top plate 110 interferes with the top plate 111 when the housing 101 is placed on the tray 102, which makes it difficult to place the housing 101. Produce.
Alternatively, the gap S between the top plate 110 of the housing 101 and the top plate 111 of the rack body 103 is eliminated, and the housing placement surface 102 a is completely outside the rack body 103 in a state where the tray 102 is pulled out. It is also possible to adopt a configuration that protrudes.
However, in such a case, when the tray 102 is completely pulled out for maintenance of the casing 101, the side wall 105 of the rack body 103 cannot support the casing 101 from the left and right, so that it is inadvertently attached to the casing 101 during work. If touched, the case 101 may fall.

  Under such circumstances, the gap S between the top plate 110 and the top plate 111 cannot be easily removed.

  Also, if the configuration in which the housing mounting surface 102a completely protrudes outside the rack body 103 without the gap S between the top plate 110 and the top plate 111 is applied, Under the situation where the tray 102 is completely pulled out for maintenance or the like, the top plate 111 of the rack main body 103 cannot be brought into contact with the top plate 110 of the housing 101 to prevent the vertical displacement of the housing 101. Therefore, if vibration occurs during maintenance, the case 101 cannot move away from the problem that the case 101 moves up and down on the tray 102 or the case 101 swings in the left-right direction, that is, the front-rear direction in FIG. .

  7 and 8, the spacer 112 is provided in the gap S between the top plate 111 of the rack body 103 and the top plate 110 of the housing 101 as shown in FIG. 7. Is inserted to prevent the vertical displacement of the casing 101.

  Such a configuration is suitable for transporting the housing housing rack 100 in which the housing 101 is stored, but the spacer 112 is usually removed after the transportation is finished and the packaging is unpacked. Since the removed spacer 112 is often lost, it is not sufficient to prevent the vertical displacement and backlash of the housing 101 in the process of actually operating the housing housing rack 100 and the housing 101.

  As a result, when the housing housing rack 100 storing the housing 101 is moved on the floor, that is, when vibration generated in the housing housing rack 100 is transmitted to the housing 101, or during maintenance of the housing 101, etc. When the tray 102 is pulled out from the rack body 103 or when the maintenance is completed and the tray 102 is re-stored in the rack body 103, in short, vibration generated when the tray 102 is put in and out even if the rack body 103 itself does not vibrate. Is transmitted to the chassis 101, the maintenance process of the chassis 101 that is performed when the tray 102 is pulled out, and the chassis 10 is stored with the tray 102 and the chassis 101 stored in the rack body 103. In any case, such as the impact of an earthquake that occurs during the normal operation process in use, the housing 101 Misaligned vertically problem of vibration is generated.

  In particular, in the case where the housing 101 is a computer or various control devices, since there are built-in weak parts such as the hard disk 113 in the interior thereof, there is a high risk of failure.

  In addition, as a rack for housing a casing using a drawer-type tray, a unit drawer safety structure of an automatic machine disclosed in Patent Document 1 is well known, and a member to be placed by superimposing vertically is positioned. As a technique for doing this, Patent Document 2 discloses a jig setting method in which the tip of four guide legs is inscribed in the corners of the four corners of a rectangular frame to prevent displacement in a horizontal plane. It is known. Further, as a technique for pressing an article to be worked from above, a box presser disclosed in Patent Document 3 is known, but this is used in order to secure adhesiveness of an adhesive during box forming. It is merely a structure that rolls while pressing the roller with a constant force on the upper surface, and the roller retracts upward according to the variation in the thickness of the box. There is no effect.

  An object of the present invention is to provide a housing housing rack that can prevent positional displacement and vibration in the vertical direction in addition to positional displacement in a horizontal plane of a housing placed on a tray and stored in a rack body. It will be.

The housing storage rack of the present invention includes a tray for placing a housing containing electronic components, a rack body for storing the tray on which the housing is placed, and a rack while horizontally guiding the moving direction of the tray. A housing housing rack including a slide rail that allows a tray pull-out operation and a storage operation with respect to the main body, and in order to achieve the above-described problem,
While providing a case locking portion that fits in the lower part of the case and prevents the case from being displaced in a horizontal plane on the case placement surface of the tray,
On the back side of the top plate of the rack body, a rotatable roller that abuts on the top plate of the housing and suppresses the vertical movement of the housing is provided between the top plate of the rack body and the top plate of the housing. It is configured to be integrated with the top plate of the rack body so as to protrude into a gap formed between the two.

  According to the housing accommodating rack of the present invention, it is possible to prevent the positional displacement and vibration in the vertical direction in addition to the positional displacement within the horizontal plane of the housing placed on the tray and stored in the rack body.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

FIG. 1 is a perspective view showing a configuration of a housing housing rack 1 according to an embodiment of the present invention in a state where a tray 2 on which a housing 101 is placed is stored, and FIG. 2 is a front view of the housing housing rack 1. 3 is a side sectional view showing the housing housing rack 1 along the arrow AA in FIG. 2, and FIG. 4 is a plan view showing the housing housing rack 1 along the arrow BB in FIG. It is sectional drawing.
5 is a perspective view showing the configuration of the housing housing rack 1 of the embodiment in a state where the tray 2 on which the housing 101 is placed is pulled out, and FIG. 6 is a housing housing rack in the state where the tray 2 is pulled out. 1 is a side sectional view showing 1. FIG.

  As shown in FIG. 3, the housing housing rack 1 is a tray 2 on which a housing 101 such as a computer incorporating various parts that are vulnerable to impact, such as a hard disk 113, various control devices, and the like is placed. A rack main body 3 for storing the tray 2 on which the casing 101 is placed, and a slide rail 104 that allows the tray 2 to be pulled out and stored while guiding the moving direction of the tray 2 horizontally. Prepare.

  Regarding the slide rail 104 including the fixed side guide rail 104a, the movable side guide rail 104b, and the floating guide rail 104c, the casters 106 and 107, and the bolt leg 108, refer to FIG. 7 and FIG. 8 in the background art section. This is the same as the case of the case housing rack 100 described. Therefore, with respect to these components, description of the configuration and function is omitted, and the same reference numerals as those used in the description of FIGS. 7 and 8 are given to the corresponding portions of FIGS.

  Inside the side wall 105 of the rack body 3, in addition to the fixed-side guide rail 104a, a housing mounting rail 6 and a hook 7 as shown in FIG. 6 are fixed. 1U = 45 mm) is a mounting means for connecting so-called pizza box type casings in the vertical direction, and is not used when mounting the tower type casing 101, and the structure itself is publicly known. There is no particular explanation here.

  Next, the configuration of the main part of the housing housing rack 1 will be specifically described.

  First, among the components of the housing housing rack 1, at the four corners of the housing placement surface 2 a of the tray 2 for placing the housing 101, as shown in FIG. A housing locking portion 4 for fitting and preventing positional displacement of the housing 101 in the horizontal plane is fixedly attached to the tray 2 in an integral manner.

  Specifically, the case locking portion 4 protrudes at the four corners of the lower surface of the case 101 and is substantially L-shaped and circumscribes the case placement protrusion 114 provided as shown in FIG. 3 or FIG. It is comprised by the fitting protrusion which has a plane cross-sectional shape.

  The fitting projection, that is, the housing locking portion 4 is formed of an elastic body such as natural rubber or silicon rubber, that is, an elastic body that is easily elastically deformed and rich in toughness, and starts from the housing mounting surface 2a. The height of the case locking portion 4 is designed to be slightly higher than the height of the case placement protrusion 114 protruding from the lower portion of the case 101.

Here, the housing locking portion 4 is configured by an elastic body that is easily elastically deformed and rich in toughness. The horizontal vibration transmitted from the floor or the like to the tray 2 via the rack body 3 or the slide rail 104 is used. Is attenuated by the housing locking portion 4 so that it is difficult to be transmitted to the housing 101, and components such as the hard disk 113 in the housing 101 are protected from vibration and impact in the horizontal direction.
In addition, the height of the case locking portion 4 is made higher than the height of the case placement protrusion 114. In particular, the case placement protrusion 114 is made of a highly rigid synthetic resin or the like. The vertical vibration transmitted from the floor or the like to the tray 2 via the rack body 3 or the slide rail 104 is attenuated by the housing locking portion 4 so that it is difficult to be transmitted to the housing 101. This is to protect the internal components such as the hard disk 113 from vibrations and shocks in the vertical direction. Therefore, if the housing mounting projection 114 itself is formed of a rubber leg or the like that takes into account the impact absorption, the housing mounting projection 114 is not necessarily attached to the housing mounting surface 2a in order to reduce vibration. Therefore, the height of the case locking portion 4 may be equal to or less than the height of the case placement protrusion 114.

In this embodiment, two housing mounting projections positioned on the near side of the lower surface of the casing 101 by the positions on the near side on the tray 2, that is, two casing locking portions 4 positioned below in FIG. 114 is supported from the front side, while two housing mounting portions 4 located on the rear side of the lower surface of the housing 101 are positioned on the rear side on the tray 2, that is, two housing locking portions 4 located on the upper side in FIG. Since the mounting projection 114 is supported from the rear side, the casing 101 supported by the four casing locking portions 4 is inadvertently moved back and forth on the casing placement surface 2a, that is, the vertical direction in FIG. There is no misalignment.
Further, the two housing mounting projections 114 located on the left side of the lower surface of the housing 101 are supported from the right side by the two housing locking portions 4 located on the left side of the tray 2, that is, the left in FIG. On the other hand, the two housing mounting projections 114 positioned on the right side of the lower surface of the casing 101 are supported from the left side by the two casing locking portions 4 positioned on the right side in FIG. As a result, the casing 101 supported by the four casing locking portions 4 is not inadvertently displaced from side to side on the casing placement surface 2a.

  That is, it is possible to prevent the positional displacement of the housing 101 in the horizontal plane on the housing placement surface 2a by these four housing locking portions 4.

In contrast to the example of FIG. 4, two positions located on the near side of the lower surface of the casing 101 by the positions on the near side on the tray 2, that is, two casing locking portions 4 positioned below in FIG. 4. While supporting the case mounting projection 114 from the rear side, the position on the rear side on the tray 2, that is, the position on the rear side of the lower surface of the case 101 by the two case locking portions 4 positioned upward in FIG. It is also possible to prevent the positional displacement of the casing 101 in the front-rear direction by supporting the two casing placement protrusions 114 from the front side.
However, in that case, when the tray 2 is pulled out and the casing 101 is placed as shown in FIG. 6, the position of the rear side on the tray 2, that is, the two casing locking portions positioned on the left in FIG. 4, the two housing mounting projections 114 positioned on the rear side of the lower surface of the housing 101, that is, the two housing mounting projections 114 positioned on the left in FIG. Since the ground needs to be grounded on 2a and the housing 101 has to be lifted more than necessary, there are some disadvantages that the mounting work becomes complicated.
In contrast to the example of FIG. 4, the two housings located on the left side of the lower surface of the housing 101 with the two housing locking portions 4 located on the left side on the tray 2, that is, on the left in FIG. 4. While supporting the mounting projection 114 from the left side, two housings positioned on the right side of the lower surface of the housing 101 with the two housing locking portions 4 located on the right side of the tray 2, that is, on the right side in FIG. By supporting the mounting projection 114 from the right side, it is also possible to prevent the positional displacement of the housing 101 in the left-right direction.
However, in this case, the housing locking portion 4 is disposed on the tray 2 when the housing mounting protrusions 114 are fixedly provided on the left and right outermost flange portions of the lower surface of the housing 101. Therefore, it is necessary to design the width of the tray 2 to be larger than the width of the casing 101. Therefore, the width of the rack body 3 for storing the tray 2 is slightly increased according to the width of the tray 2. Produce.

  That is, in this embodiment, the specific reason why the arrangement position and the mounting orientation of the case locking portion 4 having a substantially L-shaped flat cross-sectional shape are as shown in FIG. This is for the purpose of facilitating the work for placing the body 101 and reducing the width of the rack body 3, and this configuration (see paragraph 0033) facilitates the work for placing the housing 101. In addition, the rack body 3 is reduced in width.

  Instead of the housing locking portion 4 having a substantially L-shaped flat cross-sectional shape, for example, the housing locking portion 4 having a substantially ¼ arc-shaped flat cross-sectional shape may be used.

  Furthermore, in the housing housing rack 1 of this embodiment, a rotatable roller 5 that abuts on the top plate 110 of the housing 101 and suppresses the vertical movement of the housing 101 is shown in FIG. 3 or FIG. In this manner, the rack plate 3 is integrally provided on the back side of the top plate 111 of the rack body 3 in a state of protruding into the gap S between the top plate 111 of the rack body 3 and the top plate 110 of the housing 101.

  In particular, in this embodiment, as shown in FIG. 3 or FIG. 6, the front end of the rack 2 in the pull-out direction of the tray 2 on the top plate 111, that is, near the right end of the top plate 111 in FIG. It is the feature that the roller 5 is arrange | positioned in the position.

  More specifically, the position closer to the right end portion of the top plate 111 is more specifically the casing 101 placed on the tray 2 with the tray 2 completely stored as shown in FIG. 3, the rightmost part of the top plate 110 in FIG. 3 abuts the outer peripheral surface of the roller 5, and the tray 2 is completely pulled out as shown in FIG. This is a position where the innermost part of the top plate 110 in the casing 101 placed on the tray 2, that is, the left end portion of the top plate 110 in FIG.

  Next, a specific usage example of the housing accommodation rack 1 will be described.

  When storing the housing 101 in the empty housing housing rack 1, first, the housing 101 is placed on the tray 2 as shown in FIG. 6 with the tray 2 fully pulled out.

At this time, the four housing placement protrusions 114 on the lower surface of the housing 101 are accurately inscribed in the L-shaped corner portions of the fitting protrusions 4 fixed at the four corners on the tray 2. The housing 101 needs to be grounded.
In this embodiment, as shown in FIG. 6, the rear side position on the tray 2, that is, the rear side of the lower surface of the casing 101 is positioned by two casing locking portions 4 positioned on the left side in FIG. 6. A structure for supporting the two housing mounting protrusions 114 from the rear, in other words, two positioned on the left side of the lower surface of the housing 101 from the front of the two housing locking portions 4 located on the left in FIG. Since the structure for pressing the housing mounting protrusion 114 is applied, the housing 101 is positioned higher than necessary so as to get over the housing locking portion 4 and located on the rear side of the lower surface of the housing 101. There is no need to ground the two housing placement projections 114, and the placement work of the housing 101 is extremely easy.
Further, since it is not necessary to lift the chassis 101 excessively, the rollers 5 of the rack body 103 inadvertently interfere with the top plate 110 of the chassis 101 and prevent the chassis 101 from entering the rack body 103. In addition, the housing 101 can be smoothly placed.

  Then, at the time when the mounting work of the casing 101 on the tray 2 is completed, the roller 5 is, as shown in FIG. 6, the rear end of the top plate 110 of the casing 101, that is, in FIG. It is in sliding contact with the left end of the top plate 110.

  Since it is not necessary to fix the casing 101 to the tray 2 by performing a fixing operation with screws or the like after placing the casing 10 on the tray 2, the casing 101 stored in the rack body 3 is frequently replaced. Even in this case, the replacement work is easy.

  Next, the tray 2 on which the housing 101 is placed is pushed into the rack body 103, and the slide rail 104 including the fixed guide rail 104a, the movable guide rail 104b, and the floating guide rail 104c is shortened, as shown in FIG. Thus, the tray 2 and the housing 101 are stored inside the rack body 3.

While the tray 2 is moved from the position shown in FIG. 6 to the position shown in FIG. 3, the casters 106 on the lower surface of the tray 2 come into contact with the floor while supporting a part of the load of the tray 2 and the casing 101. . Therefore, in a situation where the floor is uneven, there is a possibility that the caster 106 picks up the unevenness of the floor and vibrates the tray 2 up and down, but the case 101 is placed on the tray 2. When the work is completed, the roller 5 is already in sliding contact with the upper surface of the top plate 110 of the casing 101, and the vertical displacement of the casing 101 is prevented by this roller 5. There is no problem that 101 is shaken up and down.
In addition, the lower surface of the housing 101 is supported by the housing locking portion 4 that is made of an elastic body that is easily elastically deformed and rich in toughness, and is designed to be higher than the height of the housing mounting projection 114. Therefore, the vibration in the vertical direction transmitted through the caster 106 is reliably damped by the housing locking portion 4 before being transmitted to the housing 101. Therefore, even if the housing mounting projection 114 itself is made of a highly rigid synthetic resin or the like, the components such as the hard disk 113 in the housing 101 are protected from vertical vibration and shock. be able to.
Even when the tray 2 is pulled out from the rack body 3, in the same manner as described above, the positional displacement, shaking, and vibration of the housing 101 are prevented, and components such as the hard disk 113 in the housing 101 are protected.
When the work is performed while the tray 2 is completely pulled out during the maintenance of the housing 101, and when an earthquake or the like occurs during the maintenance work, the positional displacement or shaking of the housing 101 and Vibration is prevented and components such as the hard disk 113 in the housing 101 are protected.

  Then, the roller 5 attached to the lower surface of the top plate 111 of the rack body 103 is moved to the position of the case 101 as shown in FIG. It comes into sliding contact with the front end of the top plate 110, that is, the right end of the top plate 110 in FIG.

  The housing 101 and the housing housing rack 1 are used in a state where the housing 101 is stored inside the rack body 3 as shown in FIG. 1 or FIG. 3 in a normal operation process or transportation process.

When moving the housing storage rack 1 on the floor using the casters 107 and when transporting the housing storage rack 3 storing the housing 101, the floor starts to become uneven and the transportation means sways. The rack body 3 is subjected to vibrations and vibrations under various circumstances, but the lower surface of the housing 101 is supported by the housing locking portion 4 made of an elastic body that is easily elastically deformed and rich in toughness. Since the upper surface of the body 101, that is, the top plate 110 is supported by the rollers 5 provided on the lower surface of the top plate 111 of the rack body 3, the vertical displacement of the housing 101 in the rack body 3 is prevented. Vibration and shock are also effectively mitigated.
Further, the positional deviation in the left-right direction and the front-rear direction of the casing 101 is caused by four substantially L-shaped casing locking portions 4 circumscribing each of the four casing mounting protrusions 114 on the lower surface of the casing 101. The vibrations and shocks in the left and right direction and the front and rear direction are also effectively mitigated by the housing locking portions 4.
Even when vibration or shaking due to an earthquake occurs in the operation state in which the housing 101 is stored inside the rack body 3, the displacement of the housing 101 is prevented and vibration and impact are alleviated in the same manner as described above.

  As described above, the roller 5 is arranged at the front end of the top plate 111 of the rack body 3 in the pulling-out direction of the tray 2, that is, the position near the right end of the top plate 111 in FIG. 3 or FIG. 2, the top plate 110 of the housing 101 is securely pressed by the single roller 5 in either the state where the 2 is pulled out from the rack body 3 or the state where the tray 2 is stored in the rack body 3. It is possible to prevent displacement and reduce vibration and impact.

In this embodiment, considering the cost, only one roller 5 is provided at the center of the front side end of the tray 2 in the pull-out direction of the tray 2 on the top plate 111 of the rack body 3 as shown in FIG. However, the rollers 5 may be arranged on both the left and right sides.
In addition, when it is assumed that the housing rack 1 is frequently transported with the housing 101 stored, in addition to the front end of the top plate 111 in the pull-out direction of the tray 2, the top Another roller 5 may be provided on the other end of the plate 111, that is, on the lower surface side of the left end of the top plate 111 shown in FIG.
