technical field

[0002] The present invention relates to communication devices and methods, and more particularly, to communication cable management systems and methods for managing communication cables and/or connections.

Background technique

[0003] Communication cable management systems are commonly used to route, route and manage connections to communication cables. Such communication cable management systems may include communication racks, cabinets, or wall-mounted systems such as junction box panels and bulkheads. A junction box panel (which may also be referred to as a patch panel, back panel, or cross-connect) is a hardware device used in the communications equipment industry to connect cables to terminal equipment housed in an environment (e.g., an office suite, apartment complex, etc.) . Panels are commonly available to accommodate 900-pair and 300-pair configurations, and are often mounted to walls within closets located in equipment environments. Exemplary panels include a fixing surface that is glued or fixed to a wall, and a mounting surface configured as a plurality of tangs to which connecting devices such as terminal strips are fixed. The terminal board is connected to data-carrying cables, such as external cables, which carry data to and from the environment to cables connected to, for example, terminal equipment.

[0004] In some cases, two or more rear panels are mounted in a side-by-side, spaced-apart configuration. The bulkhead mount fits in the space between the rear panels. Shelf shelves can be secured to one or both of the walls and/or rear panels. The bulkhead frame defines a cable channel through which cables may be routed for connecting the terminal strips of one of the rear panels to the terminal strips of the other rear panel. In some cases, door panels are mounted on bulkheads to protect and hide cables in cable troughs. According to one known construction available from Chartsworth Products, the door panel is secured to the shelf by four plastic quarter-turn fasteners located along each side edge of the door panel. The door panels can be removed by loosening (ie, by rotating to the open position) all four fasteners. Alternatively, the user can loosen the two fasteners on either side and rotate the door panel about the other two plastic fasteners.

[0033] According to an embodiment of the present invention, a door assembly for a communication cable management system is provided. The communication cable management system may include a communication rack, cabinet or wall mount system as a support structure on which the door assembly is mounted. According to other embodiments of the present invention, there is provided a communication cable management system including the door assembly.

[0034] Referring now to the drawings, a door assembly for a telecommunications rack, cabinet or wall mount system, generally designated at 10, is shown in FIGS. 1-13. Referring first to FIG. 1 , a door assembly 10 may include a generally planar door body or front panel 12 having a top edge 13 a , a bottom edge 13 b and side edges 14 . Handles 16 a , 16 b (described in detail below) may be secured to side edge 14 and fit within recesses 17 in front panel 12 .

[0035] Still referring to FIG. 1, the handles 16a, 16b may be mirror images of each other with respect to a vertical plane P perpendicular to the front panel 12; thus, only one handle 16a will be described below, and the discussion applies equally to the other handle 16b. Furthermore, with respect to the spatial relationship of the various components, the words "lateral", "outer" and their derivatives refer to the direction defined by the vector parallel to the front panel 12, which begins at the plane P and extends toward the side edge 14. extend. The words "inner", "inward" and their derivatives refer to the opposite direction of the word "outer";

[0036] The handle 16a may be generally U-shaped with two arms 18 bridged by a grip 19. In the illustrated embodiment, the grip portion 19 is double arcuate; it protrudes away from the front panel 12 to facilitate the user's grip, and is curved so that its center is closer to its opposite sides than its ends. Adjacent to the side edge 14 . This configuration also facilitates the user's operation whether the user grabs the grip 19 from above or below, or grabs the grip 19 at the same height as the user.

[0037] Turning now to FIGS. 2 and 3, the handle 16a includes a respective axle seat 20a, 20b at the end of each arm 18 which is seated in a groove 14c in the side edge 14. Each axle seat 20a, 20b includes a bevel surface 22 that spirals around the axle seat 20a, 20b to form a downwardly facing helical ramp. Handle pins 24a, 24b extend perpendicularly from opposite ends of the shaft base 20a, while handle pins 24c, 24d extend from opposite ends of the shaft base 20b; handle pins 24a, 24b, 24c, 24d collectively define the door rotation axis A1 (second rotation Axis A2 is defined on the opposite side handle 16b by handle pins 24a, 24b, 24c, 24d). In the illustrated embodiment, handle 16a is formed as a single member, with axle housings 20a, 20b and handle pins 24a-24d integrally formed with the remainder of handle 16a. Those skilled in the art will recognize that the handle can be formed as multiple pieces.

[0038] Referring now to FIGS. Typically mounted to the back of the front panel 12 or to the side edge 14). In this embodiment, the support plates 26a, 26b are mounted to the front panel 12 by adhesive, although other mounting techniques may be used, such as threaded fasteners and the like. The support plates 26a, 26b, which may help provide rigidity to the door assembly 10, are generally planar, but include a number of protrusions, flanges, bosses that provide structure for mounting of other components and/or provide additional functions as described below. From the Ministry and so on. For example, two bosses (not shown) may extend from the support plates 26a, 26b through holes in the front panel 12, acting as stops in the groove 17 against which the handles 16a, 16b rest. The use of two mirrored support panels 26a, 26b provides the designer the flexibility to employ the support panels 26a, 26b on doors of different widths. It will be appreciated that in some embodiments, a single support plate may be employed, or the support plate may be omitted entirely.

[0039] Referring again to FIGS. 2 and 4, near the lateral edges of the support plate 26a, the support plate 26a includes a series of ribs 27 having holes (not shown) for receiving the handle pins 24a-24d of the associated handle 16a. out). Also, two stops 29 are provided against the ends of the handle pins 24a, 24d, thereby holding the handle 16a in place. A spring 30 ( FIG. 3 ) surrounds each of the handle pins 24 a , 24 c and is mounted proximate to the rib 27 to bias the handle 16 a into a closed position in which the handle 16 a is seated in the recess 17 of the front panel 12 .

[0040] Referring back to FIGS. 2 and 3, the two toggle arms 32a, 32b are rotationally fixed at respective pivots 34a, 34b to the mounting platform 31 on each support plate 26a, 26b so that the toggle arms 32a , 32b are rotatable about respective axes A3, A4 which are horizontal and perpendicular to the front panel 12. At its lateral extremity, each toggle arm 32a, 32b includes a camming post 36 which extends to and contacts the wedge surface 22 of the adjacent axle seat 20a, 20b of the handle 16a.

[0041] Referring now to FIGS. 2 and 5, two generally vertically arranged mirrored latches 40a, 40b (only one of the two latches, latch 40a, will be described in detail herein) are provided inside the handles 16a, 16b, each Each latch covers a portion of its respective support plate 26a, 26b. The latch 40a includes a fitting hole 41 that receives a latch stopper 42 protruding from the support plate 26a. The fitting hole 41 has a sufficient length so that the bolt 40a can move vertically along the axis A5 for a short distance. The latch 40a includes an upper flange 45 extending laterally from an upper end of the latch 40a. A lock structure in the form of a latch 46 extends downwardly from the upper flange 45 . The pin 46 is received in a hole or compartment defined in a locator or guide member 46a protruding from the support plate 26a. Similarly, a lower flange 47 extends laterally from the lower end of the bolt 40a, and a lock structure in the form of a pin 48 extends downwardly therefrom through a hole or compartment located in a locating member 48a protruding from the support plate 26a. middle. Pins 46, 48 collectively define an axis of rotation A6 on which door assembly 10 is rotatable (pins 46, 48 connected to latch 40b define an axis of rotation A7 on the opposite side of door assembly 10). The upper surface of the lower flange 47 contacts a spring (not shown) that contacts the rib 49 . The spring is in compression and pushes the latch 40a downward. The latch 40a also includes a catch hole 43 at its central portion. A latch 40a is rotationally secured to each of the toggle arms 32a, 32b at respective pivots 44a, 44b.

Referring now to Fig. 2 and Fig. 6, two mirror images buckle iron baffle 52a, 52b (will only describe in detail one of two buckle iron baffles here, buckle iron baffle 52a) is installed in door bolt 40a, 40b below The back of the respective support plates 26a, 26b. The clasp 52a includes a base 51 covering the support plate 26a and a spring bar 54 protruding upward and laterally from an inner portion of the base 51 . The locking projection 56 rises from the lateral end of the spring bar 54 and is positioned to be received in one of the catch holes 43 on the latch 40a. The catch 52a also includes a finger 58 extending upwardly from the base 51 and helping to hold the latch 40a in place, and a tab 60 on the lateral end of the spring bar 54 . As will be further understood from the discussion below, the catches 52a, 52b serve as an automatic hold mechanism to keep the pins 46, 48 in their unlocked positions, and also serve as an automatic release mechanism to automatically release the pins 46, 48 under suitable conditions. return to its locked position.

[0043] Referring now to FIG. 7, according to some embodiments of the present invention, the door assembly 10 may be mounted on two communication racks 100, 102 by pins 46, 48 so as to cover the slot or space 104 between the racks 100, 102. Slot 104 generally accommodates cables that are routed between racks 100 , 102 . The presence of the pins 46, 48 received in holes or similar openings in the shelves 100, 102 prevents the door assembly 10 from being opened inadvertently. In this position ("closed position") as shown in FIG. The door assembly 10 thus serves to conceal, protect and/or accommodate cables in the slot 104 . More particularly, the pins 46, 48 of the latch 40a are disposed in a locked position in which they engage with respective mating features of the rack 100 (e.g., are received in mounting holes formed in rods or posts of the rack 100). ), while the pins 46, 48 of the latch 40b are disposed in a locked position in which they are engaged with respective fitting structures of the frame 102 (for example, received in fitting holes formed in a rod or post of the frame 102).

[0044] When the door assembly 10 is closed as in FIG. 7, the handles 16a, 16b are in the stowed position in which the arms 18 of each handle 16a, 16b are in their respective grooves 17 and are in contact with the front panel 12. Roughly parallel. Notably, because of the arrangement of the handles 16a, 16b relatively close to each other, they can be easily secured (by chains, locks with long shackles, etc.) . When the handles 16a, 16b are retracted, the axle seats 20a, 20b of the handles 16a, 16b are oriented with the upper ends of the wedge surfaces 22 facing rearwardly and contacting the cam connection pins 36 of the toggle arms 32a, 32b (see FIG. 2). The handles 16a, 16b are urged towards this stowed position by a spring 30 acting on the handle pins 24a, 24c.

[0045] Referring to FIGS. 2 and 3, when the cam connection pin 36 contacts the upper end of the wedge surface 22, the toggle arms 32a, 32b are arranged substantially horizontally. Thus, the latches 40a, 40b are in a lowered position relative to the support plates 26a, 26b. In this lowered position, the pins 46, 48 of each bolt 40a, 40b are in their respective locked positions where they are inserted through and from their respective compartments 46a, 48a to Protrude into their mating holes in the racks 100,102. As mentioned above, the latches 40a, 40b are urged downwards by springs acting on the ribs 49 and the lower flange 47 . In addition, the spring bars 54 of the catches 52a, 52b are slightly deflected from their relaxed position and press against the underside of the respective latch 40a, 40b.

[0046] If desired, without removing the door assembly 10 from the racks 100, 102, the operator can open the door assembly 10 from the left or right side to access the slot 104. To open the door assembly 10 from either side, the user simply grasps the appropriate handle 16a, 16b and rotates it so that the grip 19 moves away from the front panel 12 and sideways. The handle 16a and the linkage between the handle 16a and the pins 46, 48 serve as a transmission mechanism for converting the pins 46, 48 from their locked position to their unlocked position. More particularly, referring to Figs. 8-10, in these figures the handle 16a is rotated, the rotation of the handle 16a causing the axle mounts 20a, 20b and the handle pins 24a, 24b, 24c, 24d to rotate about the axis A1. When the axle bases 20a, 20b rotate, the wedge surface 22 of each axle base also rotates, so that finally the lower end of each wedge surface 22 faces rearward and contacts the cam connection pin 36 (when the stepped surface 37 on the axle base 20a When the cam connection pin 36 is contacted, the rotation of the handle 16a is stopped). This interaction drives the cam link pin 36 downward, which in turn rotates the toggle arms 32a, 32b about the axes 34a, 34b (clockwise from the vantage point of FIGS. 9 and 10 ). Rotation of the toggle arms 32a, 32b drives the inner ends of the toggle arms 32a, 32b upward along axis A5, which ultimately drives the latch 40a upward. This action slides or lifts the pins 46, 48 out of the holes in the frame 100 and into their respective unlocked positions, thereby releasing the left side of the door assembly 10 from the frame 100 (from the vantage point of FIG. 11 ). According to some embodiments, the pins 46, 48 slide out of the mounting holes along a sliding axis substantially parallel to the axis of rotation A6. According to some embodiments, the sliding axis extends substantially vertically.

[0047] With the pins 46, 48 of the bolt 40a released while the pins 46, 48 of the bolt 40b are still in rotational engagement with the mounting holes of the frame 102, the door assembly 10 can be moved about the axis A7 (i.e., the pins 46, 48 of the bolt 40b shaft) to the open position (see FIG. 11 ) on the right side of the door assembly 10. In this way, the pins 46, 48 of the bolt 40a and the receiving mounting holes of the frame 102 act as hinge means, and the door assembly 10 can be opened as a right side hinged door. Due to the location and configuration of the pins 46, 48 of the latch 40a, the door assembly 10 can be opened from its closed position to a position in excess of 90 degrees.

[0048] When the latch 40a is raised in response to the handle 16a being moved to its deployed position, the catch hole 43 is aligned with the protrusion 56 of the catch 52a (see FIG. 10). When this occurs, the spring bar 54 is free to spring upwards, which forces the lug 56 into the catch hole 43 . The presence of the protrusion 56 keeps the latch 40a in the raised condition automatically even if the user releases the handle 16a.

[0049] Alternatively, with the handle 16a released and the pins 46, 48 of the latch 40a inserted into the shaft holes of the rack 100, the right handle 16b can be grasped and rotated to be lifted by the toggle arms 32a, 32b Latch 40b. This action slides the pins 46, 48 of the door latch 40b into their unlocked positions so that the door assembly 10 is free to rotate about axis A6 and move to the open position (see Figure 12). In this way, the door assembly 10 can be opened as a left hinged door. Thus, it can be seen that the pins 46, 48 can be used as a door lock and hinge for the door assembly 10 on either side.

[0050] As another option for the operator, the two handles 16a, 16b can be grasped and moved simultaneously to their respective deployed positions. The deployment of the two handles 16a, 16b is such that the pins 46, 48 on either side of the door assembly 10 can be pulled out of their respective holes in the frames 100, 102 (i.e., into their unlocked positions, see FIG. 13 ). The door assembly 10 is completely removed from the racks 100,102. The presence of the two handles 16a, 16b in their respective mirrored positions facilitates two-handed movement of the door assembly 10 .

[0051] By turning the door assembly about the locking/hinge side (if one side is already engaged with its frame 100, 102) or pushing the door assembly 10 back into the frame 100, 102 (if neither side is engaged with the frame 100, 102) , which returns the door assembly 10 to its closed position (FIG. 7). The closing operation is the same for each of the left and right sides of the door assembly 10, so the closing operation will be described with reference to the left side closing, it being understood that the description applies equally to the right side closing.

[0052] Proper alignment of the door assembly 10, particularly the pins 46, 48, with the mounting structures or holes of the shelves 100, 102 may be assisted by the guide members 46a, 48a.

[0053] By pushing the protruding piece 60 on the spring bar 54 to the front panel 12, the buckle iron block 52a can be disengaged. In some embodiments, shelf 100 will include a post or other structure positioned to contact tab 60 when door assembly 10 is closed. This force disengages the protrusion 56 from the catch hole 43 on the latch 40a to automatically release the latch 40a. The bolt 40a is then free to return to its lowered position along the axis A5. This action is activated by springs acting on the ribs 49 and the lower flange 47 . When the bolt 40a is lowered, the pins 46, 48 reinsert into their mating holes in the rack 100 (ie, return to their locked positions). In this way, tab 60 acts as an automatic release mechanism for door latch 40a such that the operator need only position door assembly 10 in the closed position without operating handle 16a to lower pins 46, 48 into latching engagement.

[0054] Those skilled in the art will appreciate that the door assembly 10 and its components may take forms other than those specifically shown and described herein. For example, front panel 12 need not be planar. It may include a window for viewing internal objects, or may, along with the latch 40a or other component, provide visual access to an indicator of whether the door assembly 10 is open or closed. The support plates 26a, 26b may include some additional structures and/or omit some structures.

[0055] The handles 16a, 16b can also be configured differently. They can be designed to be rotated more or less than the 90 degree rotation shown here. They can be configured to open "outside-in" rather than "inside-out" and need not be mirror images (ie, one handle opens "inside-out" while the other opens "outside-in"). The cam surfaces 22 of the shaft seats 20a, 20b can be configured like lead screws or worm gears. The grip 19 may be straight or arcuate in only one direction.

[0056] The locking member may also take different forms. For example, in some embodiments, the toggle arms 32a, 32b may have different lengths or shapes, or may be omitted entirely so that the latch interacts directly with the wedge surface 22 . The latches 40a, 40b may be of different lengths and may take different forms (eg, may take a linear configuration). The latches 40a, 40b may rely on gravity rather than springs to hold in place, and may be identical rather than mirror images of each other (which may be cost effective). Buckle iron block 52a, 52b can save. Where an additional toggle arm or the like is included, the latch mechanism may be configured to only open one handle at a time, if this function is satisfactory.

[0057] The door assembly 10 may also be mounted on a telecommunications cabinet, telecommunications rack, or wall-mounted shelf as desired.
