DETAILED DESCRIPTION
[0055] Reference will now be made in detail to exemplary aspects of the present disclosure that are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
[0056] Referring to
[0057] The closure 10 includes a first housing piece 18 that sealingly engages a second housing piece 16 via activation of a clamp 20 that compresses a sealing block between the first housing piece 18 and the second housing piece 16, and also latches the first and second housing pieces together. In this example the second housing piece 16 is a dome cover and the first housing piece 18 is a base.
[0058] The base 18 can support telecommunications equipment, such as splice trays, fiber organization structures, cable mounting structures, etc. In addition, the base 18 includes a plurality of cable ports 22 by which cables 2, e.g., drop cables or distribution cables, enter and leave the closure 10. At any given time a port that is not used by a cable can be sealed in order to maintain an interior volume of the closure that is sealed off from external contaminants.
[0059] Referring to
[0060] The closure 30 includes a first housing piece 38 that sealingly engages a second housing piece 36.
[0061] The first housing piece 38 can support telecommunications equipment, such as splice trays, fiber organization structures, cable mounting structures, etc. In addition, the first housing piece 38 includes a plurality of cable ports 42 by which one or more cables 2, e.g., drop cables or distribution cables, enter and leave the closure 30. At any given time a port that is not used by a cable can be sealed in order to maintain an interior volume of the closure that is sealed off from external contaminants.
[0062] Referring to
[0063] The closure 50 includes a first housing piece 58 that sealingly engages a second housing piece 56 via activation of latch clamps 60 that latch the first and second housing pieces together, and a gel seal actuator 62 having a rotatable actuation handle 64 that compresses one or more sealing blocks between the first housing piece 58 and the second housing piece 56. In this example the second housing piece 56 is a dome cover and the first housing piece 58 is a base.
[0064] The base 58 can support telecommunications equipment, such as splice trays, fiber organization structures, cable mounting structures, etc. In addition, the base 58 includes a plurality of cable ports 66 by which cables 2, e.g., drop cables and/or feeder cables, enter and leave the closure 50. At any given time a port that is not used by a cable can be sealed in order to maintain an interior volume of the closure that is sealed off from external contaminants.
[0065] The example closures 10, 30 and 50 all suffer from a lack of a handling/gripping feature by which the closure can be lifted without relying on the cables 2 for grip/leverage, which can cause the cables to unduly bend and/or become damaged.
[0066] Referring now to
[0067] Turning again to
[0068] The closure 100 includes a first housing piece 106 and a second housing piece 108 that are mateable and demateable to selectively provide access to an interior volume of the closure 100. A clamp or other mechanism can be provided on the mating section 110 to snugly mate the housing pieces together, and the closure 200 can be provided with one or more sealing elements to prevent ingress of contaminants into the interior volume when the closure is in the closed configuration.
[0069] In this example, the first housing piece 106 is a base and the second housing piece 108 is a dome cover, but these are just example configurations for the first and second housing pieces.
[0070] Optionally, the first housing piece 106 can support telecommunications equipment, such as splice trays, cable fixation units, fiber organizing structures, etc., which, when the closure 100 is closed, are protected within the cover 108.
[0071] The first housing piece 106 includes one or more ports (not shown) adapted to receive one or more telecommunications cables 2 entering the interior volume defined by the first and second housing pieces.
[0072] The first housing piece 106 includes a mating section 110 adapted to sealingly mate with the second housing piece 108, and a protruding handling section 112 integral with the mating section 110, the handling section 112 further including at least one gripping element 114 and in this example, two gripping elements 114. In other examples, the handling section and/or the gripping elements are manufactured separately from the housing pieces and mounted to or affixed to one of the housing pieces. In other examples, one, three, four, five, six, seven, eight, or more gripping elements can be provided. The gripping elements 114 can be, but need not be, equally spaced circumferentially about the axis A1. In the example shown, the two gripping elements 114 are equally spaced circumferentially about the axis A1.
[0073] In this example, each of the gripping elements 114 comprises a flange 116 extending/protruding radially away from the axis A1. Each flange 116 extends radially from an outer surface 120 of a generally cylindrical cable shielding wall 118 of the handling section 112. The inner surface 122 of the cable shielding wall 118 radially surrounds and encloses the cables 2, the cable shielding wall 218 being radially farther from the axis A1 than the one or more cables 2.
[0074] It should be appreciated that the gripping elements of the present disclosure need to extend/protrude in a radial direction. In alternative examples, the gripping elements can extend/protrude from either or both of the housing pieces and in any direction, e.g., axially.
[0075] It should also be appreciated that the handling section 112 need not include a cable shielding wall 118 and, as noted, the gripping elements may protrude from any portion of the first housing piece 106, or even from the second housing piece 108.
[0076] Each flange 116 includes one or more through holes 124, each of the through holes 124 extending through the respective flange 116 in a direction perpendicular to the direction by which the flange radially extends/protrudes from the cable shielding wall 118.
[0077] In the example shown, each flange 116 includes two through holes 124. In other examples, one, three, four, five, six, seven, eight or more through holes can be provided in one or more of the flanges. In further examples, no through holes can be provided in one or more of the flanges, the flange being adapted to be grasped directly without inserting a tool into a through hole.
[0078] In the example closure 100, the flanges 116 are positioned radially farther from the axis A1 than at least one of the one or more cable ports, which are radially closer to the axis A1 than the cable shielding wall 118. This can allow for accessing the flanges 116 without touching or significantly disturbing (and potentially damaging) the cables 2. In the example closure 100 the handling section 112 is positioned closer to the proximal end 102 than the mating section 110.
[0079] In some examples of the closure 100, the mating section 110 and the handling section 112 (including the gripping elements 114) are together an integral, single piece, e.g., integrally molded or machined together.
[0080] It should be appreciated that one or more of the gripping elements 114 can be provided with one or more ergonomic features, such as specially configured grasping surfaces to facilitate gripping the gripping elements 114 by hand.
[0081] In addition,
[0082] In at least some examples, each gripping element 114 can withstand a lifting force applied directly to the gripping element (e.g., via the tool 300 inserted in one or both through holes 124) that exceeds the fully loaded weight of the closure 100. Preferably, each gripping element 114 is designed to withstand substantially more lifting force than that, e.g., at least 1.5 times, at least 2.0 times, at least 2.5 times, at least 3.0 times, at least 3.5 times, at least 4.0 times, at least 4.5 times, at least 5.0 times the fully loaded weight of the closure 100, or more, without jeopardizing the gripping element's structural integrity. In addition, in at least some examples, each gripping element 114 is designed to have sufficient durability to withstand repeated liftings of this nature at the closure's maximum weight without jeopardizing its structural integrity, e.g., at least 50 liftings, at least 100 liftings, at least 500 liftings, at least 1,000 liftings, or more.
[0083] Referring now to
[0084] The closure 200 includes a first housing piece 206 and a second housing piece 208 that are mateable and demateable to selectively provide access to an interior volume of the closure 200. A clamp or other mechanism can be provided on the mating section 210 to snugly mate the housing pieces together, and the closure 200 can be provided with one or more sealing elements to prevent or minimize ingress of contaminants into the interior volume when the closure is in the closed configuration.
[0085] In this example, the first housing piece 206 is a base and the second housing piece 208 is a dome cover, but these are just example configurations for the first and second housing pieces.
[0086] Optionally, the first housing piece 206 can support telecommunications equipment, such as splice trays, cable fixation units, fiber organizing structures, etc.
[0087] The first housing piece 206 includes one or more ports (not shown) adapted to receive one or more telecommunications cables 2 entering the interior volume defined by the first and second housing pieces 206 and 208.
[0088] The first housing piece 206 includes a mating section 210 adapted to sealingly mate with the second housing piece 208, and a protruding handling section 212 integral with the mating section 210, the handling section 212 further including at least one gripping element 214 and in this example, three gripping elements 214. In other examples, the handling section and/or the gripping elements are manufactured separately from the housing pieces and mounted to or affixed to one of the housing pieces. In other examples, one, two, four, five, six, seven, eight, or more gripping elements can be provided. The gripping elements 214 can be, but need not be, equally spaced circumferentially about the axis A2. In the example shown, the three gripping elements 214 are equally spaced circumferentially about the axis A2.
[0089] In this example, each of the gripping elements 214 is a flange that includes a radially extending foot 216. Each foot 216 extends radially from an outer surface 220 of a generally cylindrical cable shielding wall 218 of the handling section 212. The inner surface 222 of the cable shielding wall 218 radially surrounds and encloses the one or more cables 2, the cable shielding wall 218 being radially farther from the axis A2 than the one or more cables 2. This can allow for accessing the gripping elements 214 without touching or significantly disturbing (and potentially damaging) the cables 2.
[0090] Radially extending from each foot 216 is an elongate, generally cylindrical wall 224 having an outer surface 226 and an inner surface 228 that defines an elongate receptacle 230 elongated in a dimension parallel to the axis A1. The receptacle 230 has an open end 232 for slidingly receiving a gripping tool into the receptacle 230. In this example, the open end 232 of each receptacle 230 coincides with the proximal end 202 of the handling section and the closure 200.
[0091] In addition, in this example the elongate wall 224 includes an elongate slot 234 (or discontinuity) elongated in a dimension parallel to the axis that is in communication with the elongate receptacle 230, such that the elongate wall 224 has a substantially C-shaped cross-section perpendicular to the axial direction.
[0092] In some examples, the elongate wall 224 is adapted to be resiliently flexed to resiliently widen the slot 234 in order to receive a lifting/lowering/moving tool such that once the tool is received in the receptacle 230, the wall 224 resiliently returns to its relaxed position and the tool can apply force via the wall 224 to move/lift/lower the closure 200.
[0093] In some examples, the slot 234 is wide enough when the wall 224 is in the relaxed state to receive a lifting tool in the receptacle 230 via the slot 234.
[0094] It should be appreciated that the handling section 212 need not include a cable shielding wall 218, and the gripping elements may protrude from any portion of the first housing piece 206, or even from the second housing piece 208.
[0095] In the example closure 200, the flanges 214 are positioned radially farther from the axis A2 than at least one of the one or more cable ports, which are radially closer to the axis A2 than the cable shielding wall 218.
[0096] In the example closure 200 the handling section 212 is positioned closer to the proximal end 202 than the mating section 210.
[0097] In some examples of the closure 200, the mating section 210 and the handling section 212 (including the gripping elements 214) are together an integral, single piece, e.g., integrally molded or machined together.
[0098] It should be appreciated that one or more of the gripping elements 214 can be provided with one or more ergonomic features, such as specially configured grasping surfaces to facilitate gripping the gripping elements 214 by hand.
[0099] In addition,
[0100] In at least some examples, each gripping element 214 can withstand a lifting force applied directly to the gripping element (e.g., via the tool 400 inserted in the gripping element's receptacle 230) that exceeds the fully loaded weight of the closure 200. Preferably, each gripping element 214 is designed to withstand substantially more lifting force than that, e.g., at least 1.5 times, at least 2.0 times, at least 2.5 times, at least 3.0 times, at least 3.5 times, at least 4.0 times, at least 4.5 times, at least 5.0 times the fully loaded weight of the closure 200, or more, without jeopardizing the gripping element's structural integrity. In addition, in at least some examples, each gripping element 214 is designed to have sufficient durability to withstand repeated liftings of this nature at the closure's maximum weight without jeopardizing its structural integrity, e.g., at least 50 liftings, at least 100 liftings, at least 500 liftings, at least 1,000 liftings, or more.
[0101] Referring to
[0102] The stand 500 includes a support platform 501 that includes a rim 502 defining an opening 504. The rim 502 can include at least one gap 506 through which the one or more cables 2 can radially pass such that the cables 2 extend through the opening 504 when the stand 500 is properly engaged with the closure 200. A plurality of legs 508 are coupled to and support the rim 502 and allow the closure 200 to be to supported by the rim 502 in an elevated position, e.g., with the free ends of the legs 508 resting on the ground or a substantially horizontal surface.
[0103] A plurality of rods 510 extend from the rim 502 in a direction that is generally perpendicular to the plane defined by the opening 504. Each of the rods 510 is adapted to be slidingly inserted into one of the axially elongate receptacles 230 of the closure 200. In this example, there are three rods 510 corresponding to the three receptacles 200. More or fewer rods can be provided. The rim 502 is adapted to engage and support the first housing piece 206.
[0104] Referring to
[0105] The stand 600 includes a support platform 601 that includes a rim 602 defining an opening 604. The platform 601 and rim 602 can include at least one gap 606 through which the one or more cables 2 can radially pass such that the cables 2 extend through the opening 604 when the stand 600 is properly engaged with the closure 100.
[0106] The stand 600 includes a first portion 612 that includes one or more slots 614 in radial communication with a cavity 616 that is open at both axial ends, the cavity 616 being adapted to receive the cable shielding wall 118 of the closure 100, and each of the slots 614 being adapted to receive one of the flanges 116 of the gripping elements 114 of the closure 100. The cavity 616 is axially aligned (the axial dimension is indicated by the arrows A) with and in communication with the opening 604. In some examples, the maximum width of the opening 604 perpendicular to the axial direction is smaller than the corresponding maximum width of the cavity 616. The first portion 612 also includes a gap 618 that is offset from the slots 614 and axially aligned with the gap 606. More or fewer slots can be provided to correspond to the number of gripping elements, and more gaps 618 can be provided than shown.
