Description:
BACKGROUND 
       [0001]    The developments hereof relate to hinged brackets in general, and particularly as these may be used in applications for mounting communications or data equipment within a telecommunications system or enclosure. These developments further provide enhanced accessibility to both mounted and un-mounted communications or data equipment within the telecommunications system or enclosure. 
         [0002]    As a background on methods of rear accessibility in communication rack assemblies, generally, it may first be noted that components within wall mounted enclosures that require rear accessibility would normally require that the entire enclosure system swing out from the wall, or that the mounting unit swing from the enclosure system itself, to allow rear accessibility to the components mounted within the enclosure. 
         [0003]    Typically, larger units for telecommunications equipment are not wall-mounted, they are either enclosed in a cabinet and rest or anchored to the floor or rack mounted and anchored to the floor. Larger assemblies are anchored to a set of upright rails, affixed to a base on a floor or other foundation, and connected by a rail at the top, forming a substantially rectangular shape. These larger assemblies may typically allow access from both the front and the back, and do not give rise to the accessibility issues raised by typically wall-mounted smaller units for telecommunications equipment. 
         [0004]    Smaller units for telecommunications equipment mounting are generally contained within an enclosure, such as a large, substantially square enclosure. Such an enclosure may be mounted to a wall on one side, and the opposite side may be the door that provides access to the telecommunications equipment within the enclosure. Such enclosures may be designed to be mounted outdoors and made of materials that may withstand extreme temperatures and protect the telecommunications equipment within. The fact that these enclosures are often wall-mounted and required to give protection from the elements gives rise to a need for a lighter, more compact design. However, in maximizing the use of space within the enclosure to create a more compact arrangement of telecommunications equipment within the enclosure, the issue of access to every component may arise. 
         [0005]    Considerations that are generally encountered in designing systems for smaller telecommunications enclosures encompass space, accessibility, enclosure size, maintainability, inspectability, reliability, and serviceability. 
         [0006]    Prior solutions to address access to equipment that requires rear accessibility and that are mounted within an enclosure give rise to space, cost, and compromised accessibility issues. One solution may require the entire enclosure to have a hinged base on the side that is mounted to the wall, wherein that the entire base compartment swings out from the wall. This solution in itself requires a larger total volume enclosure that is capable of protruding from the wall a greater distance. This also leads to an increase in cost, and requires a greater amount of space within the enclosure so that the telecommunications equipment may be disposed efficiently within the system. Another prior solution may require mounting the electronic equipment in an enclosure that is designed so that the rails to which the equipment is mounted within the enclosure would swing independently of the enclosure. This also requires a larger enclosure and is also more costly. 
         [0007]    The solution presented herein allows for individual components that require rear access for communication or power terminations to swing themselves, instead of requiring the entire enclosure swing outward, or the rails themselves swing outward. This solution may thereby save on space, material and overall costs. Considerations that are encountered encompass space, accessibility, enclosure size, maintainability, inspectability, reliability, and serviceability. 
       SUMMARY 
       [0008]    The present apparatus is directed generally to a dual hinge bracket that allows communications and or data equipment components to swing outward from mounting points within a standard size communication rack assembly to provide rear access to the components for communications and power wiring. The apparatus may have counter swinging hinges that allow the component to move horizontally within mounting rails and swing outward and away from the rails themselves.

     DETAILED DESCRIPTION 
       [0020]    The present invention is directed generally to a dual hinge bracket that allows communications and or data equipment components to swing outward from mounting points within a standard size communication rack assembly to provide rear access to the components for communications and power wiring, inter alia. The dual hinge bracket may have counter swinging hinges that allow the component to move horizontally within a standard sized enclosure and swing outward and away from the enclosure. 
         [0021]    Accordingly, such an apparatus  100 , also referred to in some instances, as a device  100 , is illustrated, for example in  FIG. 1 , and may advantageously be used to mount a telecommunications device  110  within a standard size communication rack assembly  120  to provide rear access to the components for communications and power wiring. 
         [0022]    The apparatus  100  may be particularly adapted for use with a particular telecommunications device  110  such as the Cisco Systems, Inc. ONS 15310-MA as described herein. As such the apparatus  100  may provide for rear access to the rear of such a device  120  as well as to others or the remainder of the components within a communication rack assembly  120 . Such a configuration may provide for improved and moveable mounting of the telecommunications device  110  and advantageous accessibility within the remainder of the telecommunication rack assembly. Accessories and/or alternatives can be provided for use with the apparatus for directing and/or enhancing the nature and direction of the outward movement of the telecommunications device  110 . A system for equipment mounting and a method for use of the apparatus are also described. 
         [0023]      FIG. 2  shows a movement of a device  110  out from an enclosure  120  through use of an apparatus  100  hereof. In the more schematic views of  FIGS. 3 and 4 , which show the apparatus  100  and the device  100  apart from an enclosure  120 , one may see in  FIG. 3  the substantially flat, mounted position of a device  110  as it would be when disposed within the enclosure (not shown in  FIG. 3 ). Then, in moving to the position of  FIG. 4 , the device  110  is shown as it might be moved outwardly, see arrow  111 . During this motion the apparatus  100  will be subjected to a rotational movement, see arrow  112 , which may be achieved through the arrangement of component parts including the two hinges,  160  and  170 , described in further detail relative to  FIGS. 6-10 , below. 
         [0024]      FIG. 5  provides a top plan view of this action of apparatus  100  in movement of the device  100  relative to the respective sidewalls  121  and  122  of enclosure  120 . More particularly, in  FIG. 5A , the device  110  is shown disposed within the enclosure  120  between side walls  121  and  122 . Movement is then initiated outwardly, see arrow  111 . Then in relation to the position of  FIG. 5B , some separation is achieved from sidewall  122  as shown by arrow  115 . Then a still further movement to the exemplar position of  FIG. 5C  may achieve a clearance C between the device  110  and the sidewall  122  so that the device  110  may be substantially fully removed from within the enclosure  120 . Further rotation, see arrow  112 , and new arrow  116 , may then provide for full access to the rear  119  of the device  110 . 
         [0025]    As shown in more detail in  FIGS. 6-10 , an apparatus  100  for providing for rear access to the remainder of the components within a communication rack assembly may include several parts, many of which are moving parts: a substantially planar portion  130  disposed between a first end member  140  and a second end member  150 . The first end member  140  may be affixed to the planar portion  130  by way of a first hinge  160 . The second end member  150  may be affixed to the planar portion  130  by way of a second hinge  170 . The first end  140  may be affixed to the communication rack assembly  120  by screws or other fixing implements driven through the holes  180  in the first end member  140 . The second end member  150  may be affixed to the communication rack assembly  120  by screws or other fixing implements driven through the holes  190  in the second end member  150 . 
         [0026]    In its resting and undeployed state, the apparatus  100  may be substantially planar, as shown in  FIG. 6  as well as in  FIGS. 1 ,  3 , and  5 A, including the substantially planar portion of the second end  155 , see  FIGS. 6 and 7 , with the exception of the perpendicular portion  200  of the second end. The perpendicular portion  200  of the second end may extend out of the plane of the apparatus  100 , as shown. The holes  190  are in and through the perpendicular portion  200  of the second end of the apparatus  100 . The holes  190  in the perpendicular portion  200  of the second end member  150  may then be used to mount the telecommunications device  110  to the apparatus  100 . 
         [0027]    As shown in  FIGS. 2 ,  6 , and  7  herein, a front view of the apparatus  100  illustrates how the hinge  160  at the first end member  150  is disposed on the front of the apparatus  100 . In its undeployed and resting state, the apparatus  100  may be affixed to the telecommunications rack assembly  120  by screws or other fixing means through the holes  180 . The apparatus  100  may then, in its undeployed and substantially planar state, extend perpendicularly from a rail or other mounting portion of the telecommunications rack assembly  120  into the center of the assembly  120 , see, e.g.,  FIG. 1 . 
         [0028]    Another view as shown in  FIG. 8 , shows the right side  150  of the apparatus  100 . The view herein is of the perpendicular portion  200  of the second end  150 , the mounting holes  190 , and the hinge  170 . This view illustrates that the hinge  170  is disposed on the rear of the apparatus  100 , and is otherwise substantially hidden from the front views; but see the top portion visible in  FIG. 6 . 
         [0029]    In another view as shown in  FIG. 9  herein, a top view of the apparatus illustrates the positioning of the hinges  160  and  170  on opposite sides of the apparatus  100 . This view also illustrates the substantial planarity of the apparatus  100  from a top perspective when in a non-deployed state. Also illustrated herein is a view of an overhanging lip  210  of the substantially planar portion  130  and an overhanging lip  220  of the substantially planar portion  155  of the second end  150 . This lip may occur on both the top and the bottom of the apparatus  100  on both the substantially planar portion  130  and the substantially planar portion  155  of the second end  150 . Further illustrated is what may be asymmetrical cutaway  230  in the lip  210  and the lip  220 , allowing for freedom of range of motion of the second end member  150  relative to the main member  130  when rotated on the hinge  170 . 
         [0030]      FIG. 10  illustrates the range of motion of the hinges. The hinge  160  on the first end may allow rotation of the main member  130  to rotate from an angle of about 0 degrees, relative to the first end member  140 , through and beyond an angle of about 180 degrees relative to the first end member  140 . The hinge  170  on the second end may allow the second end member  150  to rotate from an angle of about 0 degrees relative to the main member  130 , through an angle of about 160 degrees relative to the main member  130 . 
         [0031]    In some implementations this apparatus may allow the enclosure to use front access support components (power and communications terminations on the front of the equipment versus the rear), which are less expensive than rear access support components. The device would give consumers an opportunity to elect a less expensive and generally smaller front access support unit in lieu of a more expensive and generally larger rear access unit. The front access support components may also promote convenience of access and ability to repair the internal mechanisms that may be mounted on the device. 
         [0032]    Incorporation of the device into an enclosure may result in a fewer number of overall moving parts or pieces within the overall enclosure. Other solutions may require several moving pieces or other enabling pieces to allow the communications componentry to move in such a manner as to allow rear access. For example, such a multi-piece solution might require: a separate mount for the equipment; a receiving piece to attach the mounted equipment to the overall structure, a way to attach or detach the equipment from the overall structure; a latch; and other possible moving pieces. The present device may achieve such a result with a single, hinged moving piece. 
         [0033]    The device may provide for a smaller overall enclosure that reduces the overall volume of the enclosure or the communications system. Generally speaking, the greater the depth of enclosure of a communications system, particularly one that is wall-mounted, the more difficult the access to the parts that may be in the rear of the enclosure. Inclusion of the device within an enclosure may provide for a more compact overall arrangement of the communications components. Accordingly, incorporation of the device into an enclosure may increase the efficiency of use of space within the enclosure. 
         [0034]    The manufacture of the device may be advantageous relative to the manufacture of other access solutions for telecommunications systems. The manufacture of the device may be straightforward and uses basic materials that are readily available. The cost of manufacture of the device may be less costly than comparable methods of manufacture of other access solutions for telecommunications systems. 
         [0035]    The device may also be visually more appealing than previously proposed solutions. The device may be manufactured in a manner that results in a sleek, efficient, industrial appearance. Whereas previously, devices manufactured for the mounting of telecommunications components have had a bulky and unfinished appearance, the finishes that may be used on the device are aesthetically appealing, and the design elements are minimalist and streamlined. 
         [0036]    The manufacture of the device may be achieved through use of commercially available heavy-duty piano hinges and cold rolled steel plating. In one embodiment, the cold rolled steel plating may be of the 11-gauge variety. The cold rolled steel and the heavy-duty piano hinge may be electrically spot welded to the steel plate. The apparatus may be then be finished with a clear anodized coating, or may remain unfinished. The clear anodized coating may give the apparatus a clean and finished appearance, and may also protect the apparatus from degradation and ordinary wear and tear. 
         [0037]    The device may be manufactured by securing the hinges to the mounting plates in opposing directions. Thereby, the apparatus, when mounted in the overall system, may swing laterally and outward. The device may be designed to accommodate the weight and dimensions of a desired component or electrical wiring, which may thereby be mounted to the device in a structurally sound manner. The device may then swing laterally and outward while bearing the weight of the component or electrical wiring. 
         [0038]    The device may be specially adapted to secure a Cisco Systems, Inc. ONS 15310-MA Optical Multiplexer in a 19″ telecom rack assembly. The Cisco ONS 15310-MA weighs between about 21 and about 34 lbs depending on how it is equipped. The device may be designed to support approximately 40 to approximately 50 lbs when using cold-rolled steel. 
         [0039]    For such a weight, and when using cold rolled steel, the thickness of the device may be a uniform thickness of about one-half of one inch (0.5″) to about twenty-three hundredths of an inch (0.1″). The thickness may depend on the commercially available steel used in the manufacture of the apparatus. 
         [0040]    The shape and/or dimensions of some particular embodiments may include: about 10.375 inches in length (parallel to the hinges); about 7.5 inches in width (perpendicular to the hinges). A first plane of the L-shaped portion of the apparatus may be 1.5313 inches in width, and a second plane of the L-shaped portion of the apparatus may be about 0.09063 inches in width. The radius of the holes at the first end of the apparatus may be about 0.1297 inches, and the radius of the holes at the second end of the apparatus may be about 0.1094 inches. The range of motion of the hinge at the first end of the apparatus may be between about 0 degrees and up to 180 degrees, and the range of motion of the hinge at the second end of the apparatus may be between about 0 degrees and up to about 160 degrees. 
         [0041]    The hole alignment on both the first and the second ends of the apparatus may be configured to adapt to the mounting holes on the Cisco ONS 15310-MA. The hole alignment on both the first and the second ends of the apparatus may also be configured to adapt to mounting holes in other manufacturers&#39; systems. 
         [0042]    The device may be advantageous over current solutions in that it has been designed and manufactured in such a way as to reduce or otherwise be adapted to overall cabinet size, reduce cost of manufacture of the apparatus and of the overall system, and make the overall system easier to install, access, and maintain. This created an overall system that may simplify accessibility to a component of the machine that requires rear access.
