Abstract

Abstract An optical fiber cabinet for enclosing various optical fiber connections and/or terminations. The optical fiber cabinet includes a frame which defines an optical fiber connection-termination area with the frame including a base having a bottom opening, vertical support members, and a removable upper frame member. Clam-shell doors are rotatably attached to the vertical support members of the frame and have a closed and open position. In the closed position, the clam-shell doors cooperate with the frame to enclose the optical fiber connection-termination area. In the open position, the clam-shell doors are disposed away from the optical fiber connection-termination area to allow both horizontal and vertical access to the optical fiber connection-termination area. A connection box within which the optical fiber connections are mounted is disposed within the optical fiber connection-termination area of the cabinet and includes a door rotatable between a closed and open position. The vertical support members of the cabinet are sized such that the connection box door is permitted to rotate substantially more than 90° between the closed and open positions when the clam-shell doors are in the open position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 125 words
An optical fiber cabinet for enclosing a plurality of optical fiber connections and terminations, said cabinet comprising: a frame defining an optical fiber connection-termination area, said frame including at least two vertical support members, a removable upper frame member releasably secured to the vertical support members, and a base having a bottom opening; a plurality of clamshell doors attached to said vertical support members and having a closed position wherein said doors cooperate with said frame to enclose the optical fiber connection-termination area and an open position wherein said doors are disposed away from said optical fiber connection-termination area to allow vertical and horizontal access to said optical fiber connection-termination area; and means for rotating said doors between said closed position and said open position.
Claim 2
Dependent Claim 125 words
An optical fiber cabinet for enclosing a plurality of optical fiber connections and terminations, said cabinet comprising: a frame defining an optical fiber connection-termination area, said frame including at least two vertical support members, a removable upper frame member releasably secured to the vertical support members, and a base having a bottom opening; a plurality of clamshell doors attached to said vertical support members and having a closed position wherein said doors cooperate with said frame to enclose the optical fiber connection-termination area and an open position wherein said doors are disposed away from said optical fiber connection-termination area to allow vertical and horizontal access to said optical fiber connection-termination area; and means for rotating said doors between said closed position and said open position.
Claim 3
Dependent Claim 77 words
An optical fiber cabinet according to claim 1 wherein said optical fiber cabinet includes a connection box disposed within said optical fiber connection-termination area such that said plurality of optical fiber connections and terminations are mounted with said box, said connection box includes a frame, at least one door, and at least one pivot connection wherein the door is attached to the frame through the pivot connection for rotation between a closed position and an open position.
Claim 4
Dependent Claim 73 words
An optical fiber cabinet according to claim 2 wherein said vertical support members of the cabinet frame have a first width and said connection box frame has a second width such that said first width is less than said second width wherein said box door is permitted to rotate about said box pivot connection to a position substantially outside said optical fiber connection-termination area when said clam-shell doors are in the open position.
Claim 5
Dependent Claim 37 words
An optical fiber cabinet according to claim 3 wherein said connection box door is permitted to rotate substantially more than 90 degrees between said closed and open positions when said clam-shell doors are in the open position.
Claim 6
Dependent Claim 29 words
An optical fiber cabinet according to claim 3 wherein said connection box is sized to pass within said vertical support members when said removable upper frame member is removed.
Claim 7
Dependent Claim 30 words
An optical fiber cabinet according to claim 1 wherein said cabinet includes means for securing said clam-shell doors to said frame when the clam-shell doors are in the closed position.
Claim 8
Dependent Claim 39 words
An optical fiber cabinet according to claim 1 wherein said upper frame member includes door lift brackets which extend outward from the upper frame member to engage the clam-shell doors when the clam-shell doors are in the closed position.
