Abstract
Abstract An apparatus is described for the storage of the fibers of glass-fiber cables (23) in distribution devices in a telecommunication network, such as, for example, in casings (9) of end distributors or distribution frames (10). In order to be able to store, in a break-safe and manipulatable manner a splice reserve, wound up as, for example, in a splice cassette (58) with a movable feed cable (21), at least one cassette box (1), is provided and which is designed to receive a cassette (20). The box (1) is stored in a casing (9, 10) of the distribution device, and is provided with a removal opening (7). The box (1) can be moved from an essentially vertical storage position in the casing (9, 10) to an essentially horizontal removal position with the removal opening (7) located at the top. With this structure, the ends of the glass-fiber cables (23) are, on the one hand, well-housed inside the casing (9, 10) when the box (1) is in its vertical storage position and, on the other hand, when box (1) is in its horizontal removal position easily removed through the top-located removal opening (7).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
An apparatus for the storage of fibers of glass-fiber cables in a distribution device used in a telecommunication network, said apparatus comprising: (a) a casing for receiving at least one cassette for stock fiber lengths stored in a winding form, said cassette being removable from the casing for removal of said fibers; and (b) at least one cassette box for placement in said casing, said box forming a removal opening to receive said cassette, said box being movable from a substantially vertical storage position in said casing to a substantially horizontal removal position with said opening positioned at the top of said box.
Claim 2
Independent Claim
103 words
An apparatus for the storage of fibers of glass-fiber cables in a distribution device used in a telecommunication network, said apparatus comprising: (a) a casing for receiving at least one cassette for stock fiber lengths stored in a winding form, said cassette being removable from the casing for removal of said fibers; and (b) at least one cassette box for placement in said casing, said box forming a removal opening to receive said cassette, said box being movable from a substantially vertical storage position in said casing to a substantially horizontal removal position with said opening positioned at the top of said box.
Claim 3
Dependent Claim
104 words
The apparatus of claim 1, wherein said box is supported in said casing by a slide-tilt bearing means, said bearing means being formed from a tilt axis supported by at least two angle plate means arranged on an end wall means of said box, said wall means being adjacent to said opening, said axis being further supported by at least two guide rail means secured to said casing having at least one guide slot means for providing a sliding bearing surface for said axis, said slot means being aligned substantially perpendicularly to and terminating adjacent an aperture formed in the side of said casing.
Claim 4
Dependent Claim
107 words
The apparatus of claim 1 or 2, wherein said casing comprises a frame having a transport hoist means for at least one shunting fiber, said hoist having at least one guide pulley means supported adjacent an upper end of said frame and at least one guide pulley means supported adjacent a lower end of said frame, said apparatus further comprising a transport cable means for positioning around said upper and lower pulley means and a transport clamp means for detachably connecting at least one shunting fiber thereto, said transport hoist means being aligned substantially parallel to said box when said box is in said vertical storage position.
Claim 5
Dependent Claim
94 words
The apparatus according to claim 1, wherein said box is adapted to receive a plurality of cassettes for positioning therein side by side, at least one of said cassettes being equipped with a form means, said form means having means for winding a feed cable thereon, said form means further having means for receiving glass-fibers of a splice reserve, said form means further having at least one guide channel means in communication with both said winding means and said receiving means for transfer of said cable from said winding means into said receiving means.
Claim 6
Dependent Claim
54 words
The apparatus of claim 4, wherein said winding means comprises a winding slot and said receiving means comprises a cavity, and said winding slot lies in a plane substantially parallel to a plane in which said cavity lies, and said channel means lies between and connects said winding slot plane with said cavity plane.
Claim 7
Dependent Claim
32 words
The apparatus of claim 5, wherein said winding slot comprises a winding disk formed in said winding slot plane, said disk having a radius that is greater than substantially about 30 millimeters.
Claim 8
Dependent Claim
51 words
The apparatus of claim 5, wherein said cavity is formed from a plurality of web means positioned adjacent the edges of a side wall of said form means, said web means having a height H above the surface of said side wall corresponding approximately to the thickness D of said cassette.
Claim 9
Dependent Claim
14 words
The apparatus of claim 7, wherein said cassette is positioned between said web means.
Claim 10
Dependent Claim
51 words
The apparatus of claim 7, wherein said form means has a length L and said cavity has a length l, said L being greater than l, said side wall having formed outside said cavity at least one transfer channel for conducting said cable from outside said side wall to said disk.
Claim 11
Dependent Claim
55 words
The apparatus of claim 9, wherein said form means comprises two side walls superposed in a sandwich-like manner, said side walls having mirror-image, elongated, oval-shaped guide webs, said webs enclosing between them guide channels for said feed cable, said cavity having bag-like pockets for receiving glass-fibers of the movable splice reserve enclosed by said webs.
