This application is based upon and claims the benefit of priority from Japanese patent application No. 2022-132228, filed Aug. 23, 2022, the disclose of which is incorporated herein in its entirety by reference.
The present disclosure relates to a device mounting mechanism and a device mounting method for a rack mount, whereby a device having a width larger than a frontage opening between columns can be mounted on a base provided inside the rack mount.
As a rack mount related to this application, a 19-inch rack defined by the EIA (Electronic Industries Association) standards is used.
Patent Document 1 (Japanese Unexamined Patent Application, First Publication No. 2021-129055) describes a technique related to such a rack mount.
An overview of the configuration of the rack mount described in Patent Document 1 will be described with reference to
The rack mount 100 used here is an EIA standard 19-inch rack having a plurality of columns 1, a base 3 erected in an inner space of the columns 1, and a shelf board 10 installed horizontally on the columns 1.
As shown in
In the following description with reference to
As shown in
As shown in
The link mechanism 22 rotatably supports the holder 21 in the horizontal plane along the arrow A1-A2 direction, and has a first movable link LA and a second movable link LB with different lengths to each other.
The base ends of the first movable link LA and the second movable link LB are provided rotatably about two base-side vertical shafts a1 and b1, and are pivotally supported on fixed portions 30 and 31 that are positioned apart in the lateral direction (the x-axis direction of the rack mount 100) on the base 3.
The distal ends of the first movable link LA and the second movable link LB are rotatably provided about two holder-side vertical shafts a2 and b2 positioned on the holder 21 with an interval therebetween.
The length dimension of the first movable link LA is larger than that of the second movable link LB.
Moreover, the distal end of the first movable link LA is rotatably connected to an intermediate portion of the holder 21 via the holder-side vertical shaft a2. Furthermore, the distal end of the second movable link LB is rotatably connected to one end (right end in the figure) of the holder 21 via the holder-side vertical shaft b2.
Furthermore, the base-side vertical shafts a1, b1 and the holder-side vertical shafts a2, b2 rotatably support the movable links LA, LB with respect to the base 3 and the holder 21 via pins (not shown).
Moreover a connector 27A is installed on the surface of the base 3 side, and a connector 27B to be coupled to the connector 27A is provided on the device M set at the other end (left end in the drawing) of the holder 21 where the movable links LA and LB are not provided.
On the holder 21 side, the connector 27B is electrically connected to the device M when the device M is attached to the holder 21.
These connectors 27A and 27B are engaged with each other and electrically connected when the holder 21 rotates in the direction of arrow A2 and comes into contact with the base 3. Further, when the holder 21 rotates in the direction of arrow A1, and separates from the base 3, they are separated from each other.
In the device mounting mechanism 102 configured as described above, the first movable link LA and the second movable link LB having mutually different lengths are installed as the link mechanism 22. Moreover, the proximal end and the distal end of the first movable link LA and the second movable link LB are rotatably connected in the horizontal plane along the arrow A1-A2 direction via the base-side vertical shafts a1, b1 and the holder-side vertical shafts a2, b2. Therefore, by means of the link mechanism 22 as shown in
Then, as shown in
Furthermore, as shown in
Moreover, in the device mounting mechanism 102, after the holder 21 is rotated (rotated in the direction of arrow A2) in the horizontal plane (horizontally moved in the direction of arrow X1) and horizontally moved so that it is moved from the perpendicular state to the parallel state by the link mechanism 22, then as a final operation, as shown in
At this time, the holder 21 can move horizontally rearward as indicated by the arrow Y2 by each rotation of the first movable link LA and second movable link LB. Therefore, as shown in
This disclosure has been made in view of the circumstances described above, with an object of providing a device mounting mechanism and a device mounting method that are capable of attaching and detaching a device to and from a rack mount while supporting the device, with a simple configuration.
In order to achieve the aforementioned objects, the present disclosure adopts the following configuration.
A device mounting mechanism according to the present disclosure is a device mounting mechanism that loads a device into an internal space within a plurality of columns constituting a rack mount, and includes: a pair of columns provided parallel to each other; mounters respectively supported by the pair of the columns so as to be movable in a direction intersecting a plane containing these columns; and a mount bar supported substantially horizontally by connecting one end to one mounter and the other end to the other mounter so as to be rotatable about shafts substantially parallel to the columns, and is characterized in that the mount bar supports an upper surface of the device within a space surrounded by the columns, and at least one of the one end and the other end is connected to a shaft so as to be movable in a direction connecting the shafts.
A device mounting method according to the present disclosure is device mounting method for a rack mount that loads a device into an area within a plurality of columns constituting the rack mount, and includes: rotatably supporting one end and the other end of a mount bar having a length substantially equal to the width of the area surrounded by the support, by means of mounters movable in the depth direction of the area; orienting the mount bar obliquely with respect to the depth direction within the area; attaching the device to the obliquely oriented mount bar along the mount bar; and rotating one end and the other end of the mount bar about shafts to thereby move the device in the depth direction while reducing the inclination of the device.
A device mounting mechanism according to a minimum configuration of the present disclosure will be described with reference to
A device mounting mechanism 102A for loading a device into an internal space within a plurality of columns 1 constituting a rack mount includes: a pair of columns 1 provided parallel to each other; mounters 11 supported by the pair of columns 1 so as to be movable in a direction intersecting a plane containing these columns 1; and a mount bar 13 supported substantially horizontally by connecting one end to one mounter 11 and the other end to the other mounter 11 so as to be rotatable about shafts 12 substantially parallel to the columns, and is characterized in that the mount bar 13 supports an upper surface of the device within a space surrounded by the columns 1, and at least one of the one end and the other end is connected to the shaft 12 so as to be movable in a direction connecting the shafts 12.
According to the above configuration, the mount bar 13 can rotate about the shafts 12 in the direction of arrow a or arrow b in
A device mounting mechanism according to one embodiment of the present disclosure will be described with reference to
In the illustrated example, the inside of the four vertically arranged columns 1 is the device mounting area.
Hollow rod-shaped guide rails 110 are provided parallel to each other on the top of the columns 1 to connect the front and rear columns 1. Moreover, a plate-shaped base mount 111 is connected to the base ends of the columns 1, respectively. A guide member 112 protrudes upward at a predetermined position on an upper surface of the base mount 111, and guides the insertion direction of a device when operating the device is mounted using the guide rails 110. The guide function of the guide member 112 will be described later together with the operation of one embodiment. A flat plate-shaped base 113 is vertically provided at a position behind the guide member 112 (at the back of a rack) and supported by the base mount 111.
The mounters 121 have a plurality of rollers 122 rotatable about a horizontal axis on each of one side and the other side. As shown in
Support members 123 are arranged below the mounters 121 and vertically support the shafts 124 respectively.
The shaft 124 provided on one support member 123 of the pair of mounters 121 provided on each of the guide rails 110, rotatably supports one end (left side in
Since the mounters 121 can move parallel to each other, the mount bar 120 supported by the above configuration is supported so that one end and the other end can move freely along the guide rails 110, and is rotatably supported about each shaft 124. Further, the other end of the mount bar 120 is further configured so that the shaft 124 can move within the elongated hole 125, and is therefore supported so that the rotation center can move along the longitudinal direction of the mount bar 120.
The configuration of a device 130 as a supported object supported by the mount bar 120 will be described with reference to
The device 130 has a configuration in which electronic components 132 are mounted on the top surface (surface) of a substrate 131. The upper edge of the substrate 131 is provided with brackets 133 and 134 for attachment to the mount bar 120. Moreover, brackets 135 and 136 are provided on the lower edge of the substrate 131 so as to be symmetrical with the brackets 133 and 134. Note that the lower brackets 135 and 136 are set at a distance from the edge of the substrate 131, so that the relative position with the mount bar 120 is the same positional relationship as that of the upper brackets 133 and 134 when the device 130 is mounted upside down.
Moreover the lower brackets 135 and 136 are not only used for mounting in the case of arranging upside down as described above, but are also used as guided members that regulate parallelism of the base 113 with the substrate 131 due to contact with the guide member 112 on the upper surface of the base mount 111. How the lower bracket 135 or 136 functions as a guided member will be described in detail in the description of the operation of the embodiment with reference to
A connector 137 to be connected to the connector 114 (see
Since the brackets 133 to 136 are detachably attached to the mount bar 120, they are constructed of elastically deformable material or provided with threaded holes for bolting, so that the mount bar 120 can be sandwiched against the upper edge (or the lower edge) of the substrate 131.
The operation of the device mounting mechanism of one embodiment having the above configuration will be described together with each step of device mounting.
As shown in
During this operation, the shaft 124 supported by the mounter 121 on the right side in the drawing can move within the elongated hole 125, so that the mount bar 120 can be obliquely arranged at a predetermined angle.
The device 130 is oriented obliquely to the extent that it can pass through the space between the front columns 1 and 1, and is passed between the columns 1 and 1. The device 130 is attached to the mount bar 120 by hooking the brackets 133 and 134 to the mount bar 120.
The operation of bringing the device 130 into the area surrounded by the plurality of columns 1 and attaching it to the mount bar 120 is performed while the operator holds the device 130 by hand. However it can be easily completed by hooking and fixing the brackets 133 and 134 to the mount bar 120 without intruding too much to the back of the area surrounded by the columns 1.
With the device 130 attached to the mount bar 120, then while pushing one end (left side) of the mount bar 120 farther than the other end (right side), as shown in
After the device 130 supported by the mount bar 120 reaches the position shown in
The operation of the device mounting mechanism in the final stage of alignment and attachment of the device 130 will be described with reference to
In the position indicated by
At such an angle, as shown in
When the mount bar 120 is further rotated centered on the left shaft 124 to an angle more nearly parallel to the base 113, then as shown in
When the mount bar 120 is further rotated centered on the left shaft 124 to give the angle shown in
That is, the device 130 is placed in a position substantially parallel to the base 113 within the rack mount, and while the mounter 121 is slid along the guide rail 110 in this state, the mount bar 120 is moved parallel in the depth direction, and the device 130 integrally supported by the mount bar 120 is brought closer to the base 113, and the connector 137 is inserted into the connector 114. By connecting the connectors 114 and 137 in this way, the mounting of the device 130 in the rack mount is completed, and the device 130 is electrically connected to the rack mount side (to other devices mounted on the rack mount).
The positional relationship between the bracket 135 and the guide member 112 for guiding when the device 130 is attached by contact between the guide member 112 and the bracket 135 serving as a guided member shown in
Since the guide member 112 is arranged on the base mount 111, its position (distance from one side of the right side of the base mount 111) is set to L1 as shown in
Also, the positions of the brackets 134 and 135 are arranged at the same distance as the brackets 135 and 136 in consideration of the case where the device 130 is installed by reversing it. When the connectors 114 and 137 shown in
The distances L1 and L1′ are specified by the mounting positions of the brackets 133 to 136 on the mount bar 120 (where in the longitudinal direction of the mount bar 120 the brackets 133 to 136 are hooked or sandwiched). However, these attachment position of the brackets to the mount bar 120 can also be adjusted by sliding in the longitudinal direction of the mount bar 120. That is, the distance L1 and the like can be changed according to errors in mounting positions of the brackets 133 to 136 on the substrate 131, and usage conditions.
As preparation work for a series of operations for attaching the device 130 to the mount bar 120, the mounting position of the device 130 in the longitudinal direction of the mount bar 120 is determined so that the bracket 135 is arranged at the position shown in
Further, regarding the brackets 133 and 134 and the brackets 135 and 136 of the device 130, when the device 130 is turned upside down the lower bracket 133 or 134 can be used as a guided member, and the device 130 can be mounted in a predetermined position in a manner similar to that shown in
As described above, the mount bar 120 is slanted with respect to the base 113, and the device 130 wider than the opening of the rack mount is attached, and is moved in the depth direction while being rotated so as to become parallel to the base 113. By so doing, the device 130 can be rack-mounted and the connectors 114 and 137 can be connected.
On the other hand, as in a Comparative Example 1 shown in
Also, as in a Comparative Example 2 shown in
Thus, in the one embodiment, the device 130 supported by the mount bar 120 can pass obliquely between the columns 1 by turning the mount bar 120 centered on the shafts 124. After that, the device 130 can be carried in to a predetermined position and attached while facing in a substantially parallel direction in which the connectors 114 and 137 can be fitted. Since the mount bar 120 has a structure in which one end and the other end are supported centered on the shafts 124, the device mounting mechanism can be configured with relatively lightweight members.
As a configuration for supporting both ends of the mount bar 120 so as to be movable in the depth direction, a mechanism that replaces the support of the mounters 121 by the guide rails 110 may be adopted.
Also, the length and shape of the mount bar 120, the shape of each part constituting the device 130, and the like are not limited to the one embodiment described above.
In the device mounting mechanism described in Patent Document 1, the construction is such that the members such as the first link LA and the second link LB that constitute the link mechanism 22, are supported in a cantilevered state by the fixing portions 30 and 31 and protrude. Therefore, in order to move the device M while maintaining it horizontally, it is necessary to increase the thickness of the members such as the first link LA and the second link LB of the link mechanism 22, or the fixing portions 30 and 31, to increase the rigidity of the entire mechanism 22, which makes it difficult to reduce the thickness of the device mounting mechanism. As a result, there is a problem in that the device mounting mechanism becomes large, and the effective space available for storage inside the rack mount becomes small.
According to the present disclosure, for example, within an area surrounded by a plurality of columns, the mount bar whose both ends are rotatably supported, can be moved to the back of the area while being rotated, and both ends of the mount bar are supported. Therefore, it is possible to reduce the weight and size of the device mounting mechanism.
In the above, one embodiment of the present disclosure has been described in detail with reference to the drawings, but the specific configuration is not limited to this one embodiment, and design changes and the like not departing from the scope of the present disclosure are also included.
Accordingly, the disclosure is not to be considered as being limited by the foregoing description, and is only limited by the scope of the appended claims.
The present disclosure can be used to mount a device on a server rack on which electronic devices such as servers are mounted.
