    Field of Invention
    [0001] The present invention relates to casings for buried underground utility lines. One use of the invention is for making splice connections for fiber optic communication lines. Background
    [0002] In the past, underground utilities enclosures were characterized by permanent underground installations, in which a sealed pedestal housing with splice connections was stored in a grade level enclosure (“grid”). ”). Alternatively, above-ground pedestals were characterized by permanent fixtures with access to splice connections made when adding a new service, for example.
    [0003] The present invention allows a pedestal housing to be easily converted from an installation aligned with the grade below ground to a pedestal installation above ground, or vice versa. Invention Summary
    [0004] An underground electrical utility chamber housing and distribution system for converting between a grade-aligned installation and an above-ground pedestal installation, convertible in any form. The system includes a grade level box or chamber that contains a pedestal housing. The base of the pedestal housing includes a plug adapted for releasable connection to an access opening in a cover for the grade level box. The pedestal and plug assembly is releasably mounted to a swingarm inside the grade level box. The swing arm holds the assembly in a stored position inside the box. Underground electrical cables, such as fiber optic conduits contained in the grade level box, are connected to contacts within the pedestal housing. The pedestal assembly, in its stored position, is part of a grid-aligned installation. A cover plate provides at least a portion of a lid for the box, in its aligned position with the grade.
    [0005] The pedestal assembly can be converted to an above-ground installation by removing the cover plate from the grade level box and raising the pedestal above the ground via a hinged connection carried by the swingarm. The pedestal assembly is raised to a position where it can be removed from the swingarm and fed upward through an access opening in a cover plate cover separate from the grade level box. (In one embodiment, the cover plate cover can be the plug opening part of a cover plate broken in two parts for closing the opening in the grade level box). The pedestal assembly, including the plug and attached wiring, is pulled up through the access opening in the cover plate cover to a position above the cover from which the plug can be installed in the access opening. This positions the pedestal housing above ground, with its connections to the wiring below ground.
    [0006] The above-ground installation can be converted back to a grid-aligned installation. In this case, the plug is detached from the cover plate cover and the previous series of steps is reversed to move the pedestal assembly back to its storage position in the installation in line with the grade.
    [0007] These and other aspects of the invention will be more fully understood with reference to the following detailed description and associated drawings. Brief Description of Drawings

    [00025] Figure 1 shows an underground utility enclosure, which includes a grade level box 10. The grade level box can have several modalities typically buried below ground with an open bottom to receive wiring 12 affixed to electrical components stored in a pedestal housing 14. The pedestal housing protects underground utility connections when they are placed above ground for connection to customer service lines, for example. The grade level box itself, being placed below ground, may contain electrical connections such as utility cables or conduits, data transmission lines, service lines, fiber optic cables and other devices, lines or underground utility cables. One use is for containing fiber optic tubes having optical fibers for spliced connections when providing residential fiber optic service connections.
    [00026] The drawings illustrate a preferred grade level box having vertical side walls with a molded support mesh structure that provides an I-profile support for the pedestal housing and a top plate that supports the pedestal housing. The grade level box and below-ground wiring connections for the pedestal assembly are described in greater detail in US Patent Nos. 7,385,137 and 7,381,888 to Burke et al., assigned to Channell Commercial Corporation and incorporated herein in its entirety as a reference.
    [00027] The pedestal housing 14 shown in Figure 1 includes a dome-shaped pedestal cover 16 releasably secured at its base to a plug 18. The plug is described in detail in Burke et al. al. In one embodiment, the base of the pedestal cover is secured to a collar 20 by a clip 22. The collar is rigidly secured to a large opening in the plug, preferably by adhesively bonding thereto, although other means of securing the glue to the plug can be used. The collar can support a rigid internal mounting frame (not shown) to support splice trays or other similar contacts for splice connections or other similar connections within the pedestal housing.
    [00028] Wiring 12 extends from the interior of the grade level box, through the opening in the plug and collar, and into the pedestal housing. As mentioned, the wiring can contain splice connections, or is adapted to back splice contacts, for the provision of services to building installations. The collar contains seals 25 (shown in Figure 10) for wiring to pass through the collar and into the pedestal housing. Figures 15 to 17 show a more detailed construction of the collar 20 and plug 18 assembly.
    [00029] Figure 1 shows the pedestal housing 14 stored in the grade level box, with a solid top plate or cover 24, which provides a grade in-line installation. The cover is removable so that the pedestal housing (and the plug affixed to its base) can be raised to an above-ground position, ie converted to an above-ground pedestal installation.
    [00030] As shown in Figure 2, the pedestal housing is held in its stationary below-ground storage position by affixing it to a swing arm assembly 26, of which a fourth end is rigidly attached to an inner wall of the grade level box. The opposite end of the swingarm assembly is releasably affixed to the pedestal housing and plug assembly through a structure described in greater detail below. Swingarm assembly 26 has a hinged structure that allows the pedestal housing and plug assembly to be rotated as a unit about a horizontal axis for lifting the assembly from its storage position to a position. above the ground.
    [00031] Figure 3 shows a first step in lifting the 14/18 pedestal/plug assembly to the above-ground position. The pedestal housing and plug assembly are carried on the swingarm, and the swingarm is shown being raised toward the above-ground position, rotating the pedestal/plug assembly around the geometric axis of the articulated structure contained in the assembly. swing arm 26.
    [00032] Figure 4 shows the pedestal housing and plug in the swingarm having been rotated to an elevated position. Wiring 12 is carried by the inner pedestal frame as the 14/18 pedestal/plug assembly rotates to the above-ground position.
    [00033] Figure 5 shows the pedestal housing and plug assembly 14/18 having been removed from its swingarm assembly. The pedestal housing and plug assembly are adapted for placement in a broken cover plate cover 28 shown in Figure 5. The broken cover plate cover has a similar structure to the pedestal mounting section of the broken cover plate described. in the previously referenced '137 and '888 patents. The split cover plate cover 28 has an access opening 30 located in a pedestal mounting section of the split cover plate. The access opening also includes notched areas 32 at opposite ends configured to match the shapes of mating clamping sections 34 protruding from opposite ends of plug 18. The clamping sections 34 may comprise flexibly clips as shown in the patents '888 and '137, for example. The split cover plate cover 28 is positioned over the top of the pedestal housing, as shown in Figure 5, so that the pedestal 14 can protrude upward through the access opening 30 above the plug 18, which remains below. of the plug opening. An edge of the broken cover plate cover 28 is positioned to abut a cooperating rim 31 in the access opening to the top of the grade level box. Alternatively, the flanged edge of the broken cover plate cover 28 may rest on a top edge 33 of the grade level box when the cover plate cover is rotated to the position shown in Figure 5. Wiring 12 is shown being pulled up as a unit with the pedestal housing as the 14/18 pedestal and plug assembly is fed through the access opening in the broken cover plate cover.
    [00034] Figure 6 shows the process of passing the plug 18 through the access opening 30 in the broken cover plate cover 28. The pedestal housing 14 is angled to pass the plug 18 at its base upwards through the opening of access.
    [00035] Figure 7 shows the pedestal housing and plug assembly having been lifted through the access opening in the broken cover plate cover, ready to be positioned in the access opening 30. This view also shows a support bar shaped rigid channel 35 positioned in slotted openings on opposite sides of grade level box. The support bar provides rigid support for the center of the broken cover plate, including the free end of cover plate cover 28.
    [00036] Figure 8 shows the pedestal housing and plug assembly 14/18 in its above-ground installation on the broken cover plate. Attachment sections 34 at opposite ends of plug 18 are shown having been releasably secured to opening 30 in broken cover plate cover 28. As shown in Figure 8, wiring 12 remains attached to connections in the pedestal housing for the provision of electrical connections from below ground to above-ground pedestal assembly. The pedestal housing can be used for making fiber optic splice connections above ground, for example. Figure 8 also shows a solid split cover plate cover 36 for the provision of a two-part cover assembly from side-by-side cover plates 28, 36 which are mounted on the rim 31 for closing the top of the box. grade level. Alternatively, the cover for the illustrated installation may comprise a one-piece cover plate with profiled plug opening as shown.
    [00037] The pedestal assembly can be moved back to the storage position shown in Figure 1 by reversing the steps shown in Figures 1 to 8.
    [00038] Thus, the invention provides for the conversion of an installation aligned with the grade to a pedestal installation above ground, but the installation can be reversed to go in the other direction. In one embodiment, one or more fiber optic splice connections may be present on the pedestal when stored below ground. The pedestal can be moved above ground for access at different times when making other splice connections.
    [00039] Figure 9 shows an alternative embodiment of the broken cover plate cover: in this embodiment, a segmented broken cover plate cover 40. The free end of the broken cover plate cover includes a segmented portion in the form of a block short narrow 42 that makes a slip fit on the broken end cap. The block is releasably affixed to the free end of the broken cap by a tongue and groove fit with fasteners or other means for releasably securing the block to the end of the cap. This alternative configuration is shown with the block 42 removed from an open section 44 at the end of the broken cap 40. With the block removed, the pedestal housing and plug assembly 14/18 can be pulled up through the access opening 45 on the broken cover, without the need to tilt it, as shown in Figure 6. Once the plug section is raised above the broken cover, the block 42 can be repositioned at the end of the broken cover, with a notched region 46 on the fitted block with projection area 34 at the end of the plug. The pedestal housing and related assembly are then positioned in the above-ground pedestal installation similar to that shown in Figure 8. Support bar 35 may also be positioned in the chamber to support the free ends of the cover plate cover components, as shown in Figures 6 to 8.
    [00040] Figures 10 to 14 show a more detailed construction of the swingarm bracket assembly 26 and its attachment to plug 18. The bracket assembly includes a two-part rigid mounting bracket 48 rigidly affixed to an inner wall of the grade level box. Brackets are secured to the wall by fasteners 49. Brackets 48 hold opposite sides of an elongated swing arm 50 having its free end 52 bolted to plug 18 through fasteners 53. The free end of the swingarm fits within a shaped bracket channel 54 affixed to the inside of the plug.
    [00041] The swing arm 50 is carried in a two-part assembly, which includes a base 56 shaped like a rectangular block, and a U-shaped stop 58 rigidly affixed to the bottom of the base. The inner length of the swingarm is rigidly affixed to the top of the base by fasteners 60. The rear edges 62 of the stop 58 engage the inner face of the housing to hold the swingarm (and pedestal housing) in a horizontal position for storing the pedestal housing in the grade level box as shown in Figure 1.
    [00042] The inner end of the swingarm rotates around the horizontal axis through a hinged connection between brackets 48, for lifting the pedestal housing assembly and plug out of its storage position, as shown in Figure 3. Fasteners 53 are accessible for removing the pedestal/plug assembly from the swingarm as shown in Figure 5.
    [00043] The pivot assembly (best shown in Figure 13) includes a roller shaft 64 carried on opposite inner faces of the supports 48. The roller shaft extends through an elongated opening 66 in the base 56. An elongate pin 68 extends across the roller, and fasteners 70 secure the brackets on opposite sides of the base 56. The swing arm, together with the base 56 and the stop 58, rotates relative to the rigidly mounted brackets 48, free to rotate in around the axis 64.
    [00044] Figure 14 illustrates the range of movement of the swingarm when rotating around a horizontal axis through roller 64. Figure 14A shows the swingarm in its fixed horizontal position for maintaining the pedestal housing in storage position . In the orientation of Figure 14A, the trailing edge 62 of the stop 58 engages the inner wall of the housing. Figure 14B shows the swingarm having rotated through an angle towards the vertical position shown in Figure 14C.
    [00045] Figure 15 shows an assembly of plug 18 and collar 20, which forms a base of the pedestal housing. The plug contains a large central opening 70 with a bottom rim 72. The collar has a narrow lower section 74 aligned with and recessed in opening 70. In the alignment process, holes 76 and 78 in collar base 74 and in the plug 18 are aligned for rear attachment to swing arm 52 via fasteners 53. Preferably, the collar is rigidly attached to opening 70 by adhesive bonding techniques. The height of the lower collar section 74 is adjusted during the molding process so that the plug and pedestal assembly fit into the stored position of Figure 1.
    [00046] Figures 15 and 16 show a more detailed construction of an upper section 80 of the collar. The lower collar section 74 and the upper collar section 80 are separated by a circular hoop 82 which fits the plug 18 when the collar is seated in the plug opening 70. The upper collar section 80 has a molded top plate 82 facing the interior of the pedestal housing during a use. The top plate 82 includes sleeves and fittings, usually at 84, for containing various lengths and cross sections of conduit, wire, fiber optic cables and the like running from below ground through sealed openings in the collar and into the interior. of the pedestal housing.
    [00047] Figure 17 shows an exploded view of the assembly with the various components of the swing arm and pedestal housing assembly. This view includes an O-ring 86 which seats on the collar 82 for sealing the base of the housing cover 14 around the upper portion 80 of the collar when the clip 22 is used to secure the bottom of the cover 14 to the plug. and paste assembled.
