Description
BACKGROUND
[0001] 1. Field of the Invention
[0002] The box or enclosure described herein relates to enclosures
for containing equipment. More specifically, it relates to
enclosures for containing electrical or telecommunications
equipment with a rotating cover that opens in an upward
direction.
[0003] 2. Description of the Related Art
[0004] Enclosures for containing equipment with a rotating cover
that opens in an upward direction are known. Typical enclosures do
not provide a means of securing the cover in the open position, and
without such means gravity will close the cover unless it is held
in the open position by the user of the enclosure.
[0005] Users of such enclosures must utilize one hand to hold the
cover in the open position which severely limits their ability to
work in the interior. Alternatively the user may utilize a
screwdriver or some other tool to attempt to hold the cover open.
This is not secure and the tool often slips, letting the cover fall
shut. This unexpected closure interrupts the users access to the
interior of the enclosure, and, since the enclosures are often
formed from metal, may injure the user if her hands or head are in
proximity to the cover when it drops closed.
[0006] The enclosure described in this application addresses these
issues and provides an improved enclosure for use in such
situations.

retention member is rotatably attached to the cover and slidably
attached to the container, and wherein the retention member retains
the cover in an open position allowing access to the interior of
the container.
[0008] In some embodiments, the retention member is rotatably
attached to the cover by a mounting pin. In some embodiments of the
enclosure the retention member is slidably attached to the
container by a guide pin, and the container is provided with a slot
for slidably accepting the guide pin. The slot comprises an arcuate
section and a retention section. The guide pin is disposed in the
retention section of the slot when the cover is in the open
position and retains the cover in the open position. The guide pin
is disposed in the arcuate section of the slot when the cover is in

lip, 132 folded over at an angle to accept and retain a latch
mechanism provided in cover 134.
[0022] Cover 134 is provided for shielding the contents of the
interior of box 100. Cover 134 is rotatably attached to container
102 to allow cover 134 to be rotated from a closed position to an
open position. In the closed position, cover 134 shields and
protects the contents of the container 102. In the open position of
cover 134, the interior of container 102 is accessible to a user
thereof, allowing the installation, removal and reconfiguration of
the equipment mounted in the container 102.
[0023] Cover 134 is comprised of a front plate 136, a top plate
138, bottom plate 140 and two side plates 142. In an embodiment of
the box 100, cover 134 is formed from a single sheet of material
with plates 138, 140 and 142 formed as extensions from the front
plate 136, and then folded perpendicular to front plate 136 to form
the cover 134 and defining the interior thereof. The plates 138,
140 and 142 are then joined at corners 144, 146, 148 and 150. In an
embodiment the edges of side plates 142 are welded to the edges of
top and bottom plates 138 and 140. In other embodiments of the box
100, tabs may be provided for attachment of the side plates 142 to
top and bottom plates 136 and 138 by welding, screws or rivets.
[0024] A latch 152 may be provided for securing the cover in a
closed position. In the embodiment shown in the Figures, latch 152
is mounted through a hole in front plate 136, is provided with a
locking mechanism actuated by keys, and engages the lip 132 in
bottom wall 108 to secure the cover 134 to the container 102.
[0025] In an embodiment of box 100, cover 134 is rotatably attached
to the back plate 104 through the slot 126 by a hinge 154 attached
to cover 134 at a first edge of top plate 140. Bottom plate 140 may
be provided with a recess 156 to provide clearance to knockout
holes 128 when cover 134 is in the closed position for cables of
various types inserted through the holes 128.
[0026] Referring now to FIG. 2, the box is shown with the cover in
an open position. The box 100 is provided with means of retaining
the cover 134 in the open position. At least one side wall 110
further comprises a slot 158, having an arcuate section 160 and a
rentention section 162. A retention member 164 is also provided,
and is rotatably attached to cover 134 and configured for engaging
slot 158. In the embodiment shown, the retention member 164 is
disposed outside the container 102 and inside the cover 134. The
portion of retention member 164 located inside cover 134 is
depicted with dotted lines. In an embodiment, the retention member
164 comprises a rigid sheet or bar of material, such as metal,
plastic, wood or other rigid material, with a mounting hole 166
located in a first end of the retention member 164 and a guide pin
168 attached to a second end of the retention member 164 and
extending perpendicularly to the surfaces thereof.
[0027] In an embodiment, retention member 164 is rotatably attached
to cover 134 by providing a mounting pin 170 fixedly mounted to
cover 134 along the adjacent side plate 142. In an embodiment, the
mounting pin 170 is a threaded bolt welded to the inside surface of
side plate 142. In an embodiment, mounting pin 170 is inserted into
mounting hole 166 of retention member 164. Retention member 164 is
secured on pin 170 between the side plate 142 and a retention
device 172, which may be a threaded nut, cotter pin, or similar
means of retention.
[0028] The guide pin 168 is inserted into slot 158 and slidably and
rotatably secured therein by retention device 174. In an embodiment
of the box 100, guide pin 168 comprises a threaded bolt welded or
otherwise attached to retention member 164, and the pin 168 is
secured in slot 158 by a threaded nut 174.
[0029] When cover 134 is in the open position shown in FIG. 2, the
weight of cover 134 forces retention member 164 down and causes
guide pin 168 to rest against side plate 142 in the retention
section 162 of slot 158 thus supporting the weight of cover 134 and
retaining it in the open position.
[0030] A user of the box 100 opens cover 134 by actuating latch 152
and raising cover 134 to the open position. As cover 134 is lifted
guide pin 168 slides along arcuate section 160 of slot 158. As
cover 134 reaches the maximum upward position guide pin 168 slides
into retention section 164 of slot 158. As the user releases
support for cover 134, guide pin 168 is held by retention section
164 and cover 134 is securely retained in an open position. The
user may then access the interior of the container 102 with both
hands as necessary without a need to hold the cover 134 in the open
position.
[0031] Once the user has completed accessing the interior of the
container 102, the user lifts the cover 134 slightly to remove its
weight from the guide pin 168 with one hand, and simultaneously
rotates the retention member 164 so that guide pin 168 is in the
arcuate section 160 of slot 158. The user then lowers the cover 134
and guide pin 168 slides down arcuate section 160 of slot 158
allowing the cover 134 to close.
[0032] Referring now to FIG. 3, the box is shown from a side
perspective view in the closed configuration. The retention member
164 and slot 158 are not visible from the exterior of the box 100
when it is in the closed configuration, and are depicted with
dotted lines. As cover 134 is rotated to the closed position,
mounting pin 170 rotates toward corner 118 of container 102, and
guide pin 168 slides down the arcuate section 160 of slot 158.
Arcuate section 160 of slot 158 extends a sufficient distance to
allow retention member 164 to slide freely until cover 134 is
completely closed.
[0033] Referring now to FIG. 4, a detailed perspective view of an
embodiment of the box 100 is depicted. The cover 134 is shown in a
partially open configuration. Retention member 164 is rotateably
attached to cover 134 by disposing mounting hole 166 over mounting
pin 170 and securing it loosely there with a retention device such
as lock nut 172. The guide pin 168 is slidably engaged in slot 158
and retained there by retention device such as lock nut 174. The
arcuate section 160 and retention section 162 of slot 158 can be
clearly seen in the view of FIG. 4.
