BACKGROUND OF THE INVENTION
1. Field of the Invention
[0001] The present invention relates to racks and enclosures, and more particularly to racks
and enclosures used to house data processing, networking and telecommunications equipment.
2. Discussion of Related Art
[0002] Equipment enclosures for electronic equipment, such as data processing, networking
and telecommunications equipment have been in use for years. Over the years, a number
of different standards have been developed to enable equipment manufacturers to design
rack mountable equipment that can be mounted in standard equipment racks manufactured
by different manufacturers. One such standard is the Electronic Industries Association's
EIA-310-D standard which defines parameters for what has become an industry standard
nineteen inch equipment rack.
[0003] Nineteen inch (1inch = 2,54cm) equipment racks are used extensively in data centers
and other facilities. With the proliferation of the Internet, it is not uncommon for
a data center to contain hundreds of these equipment racks. Further, with the ever
decreasing size of computer equipment, and in particular, computer servers, the number
of electrical connectors mounted in each equipment rack has been increasing, raising
additional power distribution, cooling and cable distribution concerns at the rack
level. With these increasing concerns, there is a need for equipment racks that are
flexible enough to satisfy a variety of different requirements, capable of meeting
industry standards, and sufficiently simple in design to be cost effective, given
the quantities of these equipment racks that may be used in a facility.
[0004] US-A1-2004/0159618 discloses a device comprising the features of the prior art portion of claim 1.

This invention is not limited in its application to the details of construction and
the arrangement of components set forth in the following description or illustrated
in the drawings. The invention is capable of other embodiments and of being practiced
or being carried out in various ways. Also the phraseology and terminology used herein
is for the purpose of description and should not be regarded as limiting. The use
of "including," "comprising," "having," "containing" "involving," and variations thereof
herein, is meant to encompass the items listed thereafter and equivalents thereof
as well as additional items.
[0012] A typical data center may be designed to house a number of enclosures or equipment
racks. In one embodiment, each equipment rack may be constructed in accordance with
the teachings disclosed in
U.S. Patent No. 7,293,666, entitled EQUIPMENT ENCLOSURE KIT AND ASSEMBLY METHOD, which is owned by the assignee
of the present disclosure and is incorporated herein by reference.
[0013] Referring to the drawings, and more particularly to FIG. 1, there is generally indicated
at 10 an enclosure or equipment rack in accordance with at least one embodiment of
the present disclosure to house electronic equipment, such as data processing and
networking equipment (e.g., servers, server blades, associated power distribution
equipment, etc.) and telecommunication equipment. In one embodiment, the equipment
rack 10 is a rectangular, box-like structure that is configured such that it can be
assembled with or connected to other, similarly-shaped structures. The equipment rack
10 has a frame generally indicated at 12 configured with a front door 14, a rear door
(not shown), a pair of sides 16, 18, a bottom 20 and a top or "roof" 22. As will be
disclosed in greater detail below, in one embodiment, the equipment rack 10 is adjustably
configurable to accommodate equipment having a variety of shapes and sizes. In addition,
the equipment rack 10 can be conveniently broken down and disassembled for transport
or storage. In at least one embodiment, the equipment rack 10 may accommodate standard
twenty-three-inch and/or nineteen-inch rack mountable equipment.
[0014] Embodiments of the disclosure provide tool-less installation systems and methods
of devices, such as power distribution units, or other types of enclosure structures,
such as rails, patch panels, blanking panels, brush strip panels, fan panels, sensor
panels, and the like, that are configured for attachment to vertical mounting flanges
or rails of the equipment rack used to contain equipment including servers, networking
equipment, information technology equipment, communications equipment and other electronic
components. With reference to FIG. 1, a vertical mounting flange 24 is formed to include
a series of openings, each indicated at 26, formed in the mounting flange along a
length of the mounting flange. In one embodiment, these openings 26 are spaced apart
a predetermined distance known in the art as a 1-U distance.
[0015] In one embodiment, the systems and methods disclose structures having an attachment
configuration that is constructed and arranged to facilitate tool-less installation
and removal of the device to a pair of adjacent mounting flanges of an equipment rack.
Each attachment configuration may include one or more retention hook, or one or more
similar configuration, and any combination of such hooks and configurations. The attachment
configuration may further include one or more plunger elements configured to lock
the retention hooks in place on the mounting flange. The retention hooks and the plunger
elements are constructed and arranged to facilitate tool-less installation and removal
of the device, and to help to releasably secure the device to a pair of mounting flanges.
The systems and methods disclosed herein are suitable for releasably mounting other
structures, such as rails, patch panels, blanking panels brush strip panels, fan panels,
sensor panels, and the like, to the mounting flanges of the equipment rack.
[0016] The retention hooks are disposed along the device and are further configured such
that the device can be mounted to and removed from an equipment rack without requiring
vertical movement of the device, or without requiring the device to be gripped or
otherwise manipulated from above or below the device, or from inside an equipment
rack. The attachment configurations thereby permit the device to be added to or removed
from an equipment rack without disturbing or removing equipment or devices previously
installed within the equipment rack.
[0017] In a certain embodiment, the device may be configured to define any U height, e.g.,
1-U, 2-U, 3-U, etc., or fractional U height, and preferably defines a 1-U height.
A 1-U height device helps provide convenience and flexibility with respect to installation
and removal of devices during configuration or rearrangement of an equipment rack.
One or more devices having a 1-U height are readily and easily installed into or removed
from an equipment rack to help to configure or rearrange the equipment rack without
the addition or removal of any more devices than necessary. Other embodiments are
within the scope of the disclosure.
[0018] Referring to FIG. 2, a device, generally indicated at 28, such as a power distribution
unit, includes an elongated body 30 having a front surface 32 and a plurality of outlets,
each indicated at 34, formed along the front surface of the body. In one embodiment,
the device 28 is configured to be mounted on a front or a back of the equipment rack
10 in which openings 26 of mounting flanges 24 of the equipment rack are facing the
person installing the device. The device 28 shown in FIG. 2 has a 1-U height, but
may be configured to achieve other desired heights.
[0019] The body 30 of the device 28 has two, opposite ends 36, 38. End 36 includes an extended
flange portion 40 having an attachment configuration generally indicated at 42. Similarly,
end 38 includes an extended flange portion 44 having an attachment configuration generally
indicated at 46. The attachment configurations 42, 44 are constructed and arranged
to attach or mount the device between a pair of adjacent mounting flanges of an equipment
rack, such as equipment rack 10. The body 30 of the device 28 has a length sufficient
to span a distance between the pair of mounting flanges 24 such that the device is
mounted horizontally between the flanges. The length of the body 30 can include any
length that is sufficient to horizontally mount the device 28 between a pair of flanges
of any equipment rack size or design. In particular, the body 30 can define a length
sufficient to mount the device 28 between pairs of flanges of a 19-inch or a 23-inch
equipment rack. In other embodiments, the device 28 including attachment configurations
may be employed in a situation in which the device connects and spans between horizontally
orientated mounting flanges or rails.
[0020] Referring to FIG. 3, and with further reference to FIGS. 4A and 4B, which illustrates
end 38 of the body 30 of the device 28, in one aspect of the disclosure, the attachment
configuration 46 provided at the flange portion 44 includes a pair of retention hooks,
each indicated at 48. Each retention hook 48 is defined along an inner surface 50
of the flange portion 44 of the body 30 of the device 28. As shown, each retention
hook 48 is configured so that it slopes away from the inner surface 50 and includes
a first segment 52 that is bent with respect to the inner surface. The first segment
52 transitions to a second segment 54 that is bent with respect to the first segment
and extends along a plane that is parallel with a plane of the flange portion 44.
The space between the second segment 54 and the inner surface 50 of the flange portion
44 is sufficient to receive an edge of the mounting flange 24 therein. The retention
hooks of each attachment configuration 42, 44 are designed to extend in the same direction
so as to enable the insertion of the retention hooks within corresponding openings
26 provided in two mounting flanges 24. The retention hooks 48 may be secured in place
by moving the body 30 of the device 28 laterally, which is described in greater detail
below.
[0021] Still referring to FIGS. 3, 4A and 4B, the attachment configuration 46 is provided
with two retention hooks 48, which are spaced apart from one another a distance corresponding
to the distance of spaced apart openings 26 formed in the mounting flanges 24. Specifically,
the distance between the retention hooks 48 may correspond to the distance of two
openings 26 formed in the mounting flange 24 with one opening disposed between the
two openings. Other spacing may be selected based on design criteria. The retention
hooks 48 of each end 36, 38 of the device 28 are configured to extend into the openings
26 provided within the mounting flanges 24. Thus, all four retention hooks 48 are
inserted into four corresponding openings 26 formed in the two mounting flanges 24.
The arrangement is such that once the retention hooks 48 are inserted into their corresponding
openings 26, the body 30 of the device 28 may be shifted or moved laterally with respect
to the mounting flanges 24, depending on the direction of the retention hooks, so
that the retention hooks engage the mounting flanges.
[0022] FIGS. 5 and 6 illustrate an arrangement in which the retention hooks 48 are inserted
into openings 26 provided in the mounting flange 24 so that the retention hooks extent
into and may be moved laterally within the openings. With the embodiment disclosed
herein, the device 28 includes four retention hooks 48 that are received within four
openings 26 provided in two spaced-apart, mounting flanges 24, although only one mounting
flange is illustrated in FIG. 6.
[0023] Referring to FIGS. 3-6, one of the two attachment configurations, e.g., attachment
configuration 46, includes a plunger pin assembly 56 disposed between the retention
hooks 48. In the embodiment illustrated in these drawings, the flange portion 44 provided
on the right-hand side of the body 30 of the device 28 includes the plunger pin assembly
56. The plunger pin assembly 56 includes a larger head portion 58 and a pin portion
60. The head portion 58 extends from an outer surface 62 of the flange portion 44
and the pin portion 60 extends from an inner surface 50 of the flange portion. The
arrangement is such that the pin portion 60 of the plunger pin assembly 56 may be
extended, as shown in FIG. 4A, and retracted, as shown in FIG. 4B. When extended,
the pin portion 60 of the plunger pin assembly 56 extends into the opening 26 provided
between the two openings 26 receiving the retention hooks 48 to lock the attachment
configuration 46 in place with respect to the mounting flange 24. In one embodiment,
the pin portion 60 may be spring-loaded so that the pin portion remains in the extended
position, and by moving the head portion 58, the pin portion may be moved against
the bias of a spring or other mechanism providing the bias.
[0024] The pin portion 60 of the plunger pin assembly 56 prevents any lateral movement of
the device 28 with respect to the two mounting flanges 24 thereby capturing or otherwise
locking the retention hooks 48 in place with respect to the mounting flanges. By moving
the head portion 58 in a direction away from the outer surface 62 of the flange portion
44, the pin portion 60 of the plunger pin assembly 56 is retracted from the opening
26 in the mounting flange 24 to enable the lateral movement of the device 28. This
lateral movement enables the movement of the retention hooks 48 from their respective
openings 26. The attachment configurations 42, 46 are symmetrical and are constructed
and arranged to permit removal of the device 28 from the equipment rack 10.
[0025] In one embodiment, the device 28 may define a nominal 1-U height to provide flexibility
and convenience in configuring or rearranging the equipment rack 10. It should be
understood that the attachment configurations 42, 46 disclosed herein may be used
on any type of device, having 1-, 2-, 3- or more U height, and fall within the scope
of this disclosure.
[0026] Referring to FIGS. 5 and 6, the attachment and removal of the device 28 from two
mounting flanges 24 will be described. The device 28, such as a power distribution
unit, is positioned against the equipment rack 10 at a location in which the installer
would like to place the device. The retention hooks 48 of the device 28 are aligned
with their respective openings 26 of the mounting flanges 24. The body 30 of the device
28 is moved toward the equipment rack so that the retention hooks 48 extend through
their respective openings 26. The pin portion 60 of the plunger pin assembly 56 engages
an outer surface of the mounting flange 24. This position is shown in FIG. 5. Next,
the body 30 of the device 28 is moved laterally so that the retention hooks 48 engage
the mounting flanges 24 along the edges of their respective openings 26 so as to hold
or otherwise secure the device in place. The plunger pin assembly 56 is positioned
so that upon moving the device 28 laterally, the pin portion 60 of the plunger pin
assembly enters its respective opening to "lock" the device in place. This position
is shown in FIG. 6.
[0027] To remove the device 28 from the equipment rack 10, the plunger pin assembly 56 is
moved so that the pin portion 60 is retracted out of the opening 26 of the mounting
flange 24. Once removed, the body of the device may be moved laterally in an opposite
direction to the movement used to secure the device. At this point the retention hooks
may be removed from their respective openings to remove the device from the equipment
rack.
[0028] FIGS. 7 and 8 illustrate the construction and manner of mounting a rail generally
indicated at 70 onto mounting flanges 24 (FIG. 8). In one embodiment, the rail 70
may be configured to mount on the equipment rack 10 along a side of the equipment
rack. As shown, the rail 70, which may be configured to support any number of devices
associated with an equipment rack, or may be configured to provide lateral stability
to an equipment rack, includes an elongated body 72 having a flange 74 disposed at
each end of the body. Although FIGS. 7 and 8 show only one end of the body 72 of the
rail 70, it should be understood that the opposite end is configured to be a mirror
image of the shown end. Each flange 74 has an attachment configuration, generally
indicated at 76, which is constructed and arranged to attach or mount the rail 70
between a pair of adjacent mounting flanges 26 of an equipment rack, such as equipment
rack 10. As mentioned above, the rail 70 is configured to mount on a side of an equipment
rack; however, other embodiments of the rail may be configured to accommodate different
applications or configured to mount on the front or back of the equipment rack.
[0029] The body 72 of the rail 70 has a length sufficient to span a distance between the
pair of mounting flanges 24 defining a side of the equipment rack 10. The length of
the body 72 of the rail 70 can be any length that is sufficient to horizontally mount
the rail between a pair of mounting flanges 24 of any equipment rack size or design.
[0030] Still referring to FIGS. 7 and 8, in one aspect of the disclosure, each attachment
configuration 76 provided at the flange 74 includes a pair of retention hooks, each
indicated at 78, similar to the retention hooks 48 described with reference to the
device 28. Each retention hook 78 is defined along an inner surface 80 of the flange
74 of the body 72 of the rail 70. As shown, each retention hook 78 is configured so
that it slopes away from the inner surface 80 and is bent so that it extends horizontally
with respect to the flange 74. The attachment configuration 76 is provided with two
retention hooks 78, which are spaced apart from one another a distance corresponding
to the distance of spaced apart openings 26 formed in the mounting flanges 24. Specifically,
the distance between the retention hooks 78 may correspond to the distance of two
openings 26 formed in the mounting flange 24 with one opening 26 disposed between
the two openings. Other spacing may be selected based on design criteria. The retention
hooks 78 of each end of the rail 70 are configured to extend into the openings 26
provided within the mounting flanges 24. Thus, all four retention hooks 78 are inserted
into four corresponding openings 26 formed in the two mounting flanges 24. The arrangement
is such that once the retention hooks 78 are inserted into their corresponding openings
26, the body 72 of the rail 70 may be shifted, depending on the direction of the retention
hooks, so that the retention hooks engage the mounting flanges 24.
[0031] FIG. 8 illustrates an arrangement in which the retention hooks 78 are inserted into
openings 26 provided in the mounting flange 24 so that the retention hooks extent
into and may be moved laterally within the openings. With the embodiment disclosed
herein, the rail 70 includes four retention hooks 78 that are received within four
openings 26 provided in two spaced-apart, mounting flanges 24, although only one mounting
flange is illustrated in FIG. 8.
[0032] As with the device 28, one of the attachment configurations 76 of the rail 70 includes
a plunger pin assembly 82 disposed between the retention hooks 78. As with plunger
pin assembly 56, the plunger pin assembly 82 includes a larger head portion 84 and
a pin portion 86. The head portion 84 extends from an outer surface 88 of the flange
74 extending from the inner surface 80 of the flange. The arrangement is such that
the pin portion 86 may be extended and retracted. When extended, the pin portion 86
extends into the opening 26 provided between the two openings 26 receiving the retention
hooks 78 to lock the attachment configuration 76 of the rail 70 in place with respect
to the mounting flange 24. In one embodiment, the pin portion 86 may be spring-loaded
so that the pin portion remains in the extended position, and by moving the head portion
84, the pin portion may be moved against the bias of a spring or other mechanism providing
the bias.
[0033] The pin portion 86 of the plunger pin assembly 82 prevents any lateral movement of
the rail 70 with respect to the two mounting flanges 24 thereby capturing or otherwise
locking the retention hooks 78 in place with respect to the mounting flanges. By moving
the head portion 84 of the plunger pin assembly 82 in a direction away from the outer
surface 88 of the flange portion 74, the pin portion 86 is retracted from the opening
26 in the mounting flange 24 to enable the lateral movement of the rail 70. This lateral
movement enables the movement of the retention hooks 78 of the body 72 of the rail
70 from their respective openings 26 of the mounting flanges 24.
[0034] FIGS. 9-12 illustrate the construction and manner of mounting a rail, generally indicated
at 100, of another embodiment, onto mounting flanges 26. In one embodiment, as with
rail 70, the rail 100 may be configured to mount on the equipment rack 10 along a
side of the equipment rack. As shown, the rail 100, which may be configured to block
or otherwise cover a portion of a side of an equipment rack, or to provide air containment
within the equipment rack, includes an elongated body 102 having flanges 104 disposed
at two, opposite ends of the body. Although FIGS. 9-12 show only one end of the body
102 of the rail 100, it should be understood that the opposite end is configured to
be a mirror image of the shown end. Each flange 104 of the body 102 of the rail 100
has an attachment configuration, generally indicated at 106, which is constructed
and arranged to attach or mount the rail between a pair of adjacent mounting flanges
24 of an equipment rack, such as equipment rack 10. As mentioned above, the rail 100
is configured to mount on a side of an equipment rack; however, other embodiments
of the rail may be configured to mount on the front of the equipment rack, for example.
[0035] The body 102 of the rail 100 has a length sufficient to span a distance between the
pair of mounting flanges 24 defining a side of the equipment rack 10. The length of
the body 102 of the rail 100 can include any length that is sufficient to horizontally
mount the rail between a pair of mounting flanges 24 of any equipment rack size or
design. It should be understood that the rails including attachment configurations
may be employed in situations in which the rails connect between horizontal mounting
flanges or rails and still fall within the scope of the present disclosure.
[0036] In one aspect of the disclosure, each attachment configuration 106 provided at the
flange 104 includes three retention hooks, each indicated at 108. Each retention hook
108 extends from an edge of the flange 104 in the manner best shown in FIG. 9. As
shown, each retention hook 108 is configured so that it is bent so as to achieve an
L-shape. The retention hooks 108 are spaced apart from one another a distance corresponding
to the distance of three spaced apart openings 26 formed in the mounting flanges 24.
In the shown embodiment, the retention hooks 108 are spaced apart to correspond to
three sequential openings 26 provided in the mounting flange 24. In other embodiments,
a different spacing may be provided. The retention hooks 108 of each end of the rail
100 are configured to extend into the openings 26 provided within the mounting flanges
24. Thus, all six retention hooks 108 are inserted into six corresponding openings
26 formed in the two mounting flanges 24. The arrangement is such that once the retention
hooks 108 are inserted into their corresponding openings 26, the body 102 of the rail
100 may be shifted, depending on the direction of the retention hooks, so that the
retention hooks engage the mounting flanges 24.
[0037] FIGS. 10-12 illustrate an arrangement in which the retention hooks 108 are inserted
into openings 26 provided in the mounting flange 24 so that the retention hooks extent
into and may be moved laterally within the openings. With the embodiment disclosed
herein, the rail 100 includes six retention hooks 108 that are received within six
openings 26 provided in two spaced-apart, mounting flanges 24, although only one mounting
flange is illustrated in FIGS. 10-12.
[0038] As with the device 28 and the rail 70, one of the two attachment configurations 106
of the rail 100 includes a plunger pin assembly 110 disposed adjacent to the middle
retention hook 108. The plunger pin assembly 110 includes a larger head portion 112
and a pin portion 114 (FIG. 12). The head portion 112 of the plunger pin assembly
110 extends from an outer surface of the flange 104 and the pin portion 114 extends
from an inner surface 118 (FIG. 12) of the flange. The arrangement is such that the
pin portion 114 of the plunger pin assembly 110 may be extended and retracted. When
extended, the pin portion 114 of the plunger pin assembly 110 extends into the opening
26 receiving the middle retention hook 108 to lock the attachment configuration 106
of the rail 100 in place with respect to the mounting flange 24. In other words, the
pin portion 114 of the plunger pin assembly 110 prevents any substantial lateral movement
of the rail 100 sufficient to remove the retention hooks 108 from their respective
openings 26. In one embodiment, the pin portion 114 of the plunger pin assembly 110
may be spring-loaded so that the pin portion remains in the extended position, and
by moving the head portion 112, the pin portion may be moved against the bias of a
spring or other mechanism providing the bias.
[0039] As mentioned, the pin portion 114 of the plunger pin assembly 110 prevents any substantial
lateral movement of the rail 100 with respect to the two mounting flanges 24 thereby
capturing or otherwise locking the retention hooks 108 in place with respect to the
mounting flanges. By moving the head portion 112 of the plunger pin assembly 110 in
a direction away from the outer surface 116 of the flange 104, the pin portion 114
is retracted from the opening 26 in the mounting flange 24 to enable the lateral movement
of the rail 100. This lateral movement enables the movement of the retention hooks
108 from their respective openings 26.
[0040] FIG. 13 illustrates a rail generally indicated at 130 that is similar to the rail
shown in FIGS. 10-12. As shown, rail 130 includes a tab portion 132 having retention
hooks 108. The plunger pin assembly 110 is disposed between the retention hooks 108
to secure the rail 130 in place.
[0041] It should be understood that the types of devices incorporating the attachment configurations
of embodiments of the disclosure may include any number of assemblies and mechanisms
used with equipment racks. Other examples of such devices may include rails, patch
panels, blanking panels, brush strip panels, fan panels, sensor panels, and the like.
The rails may be used to support shelves, servers, routers, and the like.
[0042] In addition, although embodiments of the devices, rails and panels have two or three
retention hooks provided with each attachment configuration, any number of retention
hooks may be included and still fall within the scope of the present disclosure. Moreover,
although the plunger pin assembly is shown typically on the right-hand side attachment
