Abstract
Abstract A packaged optical fiber splice is held in a retainer formed by two pairs of cantilever members having inwardly facing ribs at their top edges. The members of a pair are spaced so that after pushing a packaged splice between the ribs, deforming the members slightly, the packaged splice is freely positioned between the cantilever members which are at least substantially stress free. The splice is retained by the ribs. A slot in the base of the retainer provides a seating for the lower edge of the splice and restrains the splice against longitudinal movement. A plurality of retainers are provided in an organizing tray.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
195 words
A retainer for a packaged optical fiber splice, comprising: a bottom web; two pairs of cantilever members spaced apart along said bottom web and extending up therefrom, the members of a pair spaced apart a distance slightly larger than the thickness of a packaged splice, the pairs spaced a distance less than the length of the packaged splice; an inwardly extending rib at an upper part of each cantilever member, the inner surfaces of said ribs spaced apart a distance less than the thickness of the packaged splice; an elongate slot in said bottom web and extending between said cantilever members, said slot extending for a distance substantially equal to the length of the packaged splice; said ribs on said cantilever members spaced from the base of said slot a distance at least equal to the height of the packaged splice; and the arrangement being such that a packaged splice can be pushed down between said cantilever members, the packaged splice positioned in said slot and restrained from longitudinal movement, the packaged splice positioned freely between the cantilever members, the ribs engaging over the packaged splice and the cantilever members being substantially free of stress.
Claim 2
Dependent Claim
195 words
A retainer for a packaged optical fiber splice, comprising: a bottom web; two pairs of cantilever members spaced apart along said bottom web and extending up therefrom, the members of a pair spaced apart a distance slightly larger than the thickness of a packaged splice, the pairs spaced a distance less than the length of the packaged splice; an inwardly extending rib at an upper part of each cantilever member, the inner surfaces of said ribs spaced apart a distance less than the thickness of the packaged splice; an elongate slot in said bottom web and extending between said cantilever members, said slot extending for a distance substantially equal to the length of the packaged splice; said ribs on said cantilever members spaced from the base of said slot a distance at least equal to the height of the packaged splice; and the arrangement being such that a packaged splice can be pushed down between said cantilever members, the packaged splice positioned in said slot and restrained from longitudinal movement, the packaged splice positioned freely between the cantilever members, the ribs engaging over the packaged splice and the cantilever members being substantially free of stress.
Claim 3
Dependent Claim
210 words
A retainer assembly for a plurality of packaged optical fiber splices comprising a bottom web and a plurality of retainers on said bottom web, each retainer comprising; two pairs of cantilever members spaced apart along said bottom web and extending up therefrom, the members of a pair spaced apart a distance slightly larger than the thickness of a packaged splice, the pairs spaced a distance less than the length or the packaged splice; an inwardly extending rib at an upper part of each cantilever member, the inner surfaces of said ribs spaced apart a distance less than the thickness of the packaged splice; an elongate slot in said bottom web and extending between said cantilever members, said slot extending for a distance substantially equal to the length of the packaged splice; said ribs on said cantilever members spaced from the base of said slot a distance at least equal to the height of the packaged splice; and the arrangement being such that a packaged splice can be pushed down between said cantilever members, the packaged splice positioned in said slot and restrained from longitudinal movement, the packaged splice positioned freely between the cantilever members, the ribs engaging over the packaged splice and the cantilever members being substantially free of stress.
Claim 4
Dependent Claim
210 words
A retainer assembly for a plurality of packaged optical fiber splices comprising a bottom web and a plurality of retainers on said bottom web, each retainer comprising; two pairs of cantilever members spaced apart along said bottom web and extending up therefrom, the members of a pair spaced apart a distance slightly larger than the thickness of a packaged splice, the pairs spaced a distance less than the length or the packaged splice; an inwardly extending rib at an upper part of each cantilever member, the inner surfaces of said ribs spaced apart a distance less than the thickness of the packaged splice; an elongate slot in said bottom web and extending between said cantilever members, said slot extending for a distance substantially equal to the length of the packaged splice; said ribs on said cantilever members spaced from the base of said slot a distance at least equal to the height of the packaged splice; and the arrangement being such that a packaged splice can be pushed down between said cantilever members, the packaged splice positioned in said slot and restrained from longitudinal movement, the packaged splice positioned freely between the cantilever members, the ribs engaging over the packaged splice and the cantilever members being substantially free of stress.
Claim 5
Dependent Claim
29 words
An assembly as claimed in claim 2, each retainer being offset laterally relative to the immediately adjacent retainer, whereby the retainers form a zig-zag arrangement across said bottom web.
Claim 6
Dependent Claim
25 words
An assembly as claimed in claim 2 including an organizing tray having a base, said bottom web attached to said base of the organizing tray.
Claim 7
Dependent Claim
20 words
An assembly as claimed in claim 2 including means extending from said bottom web for attachment to a support member.
Claim 8
Dependent Claim
18 words
An assembly as claimed in claim 4 said bottom web bonded to said base of said organizing tray.
Claim 9
Dependent Claim
31 words
An assembly as claimed in claim 4, said bottom web including downwardly extending projections, said projections extending through said base of said tray to attach said bottom web to said tray.
Claim 10
Dependent Claim
29 words
An assembly as claimed in claim 4, said slots extending through said bottom web, an upper surface of said base of said tray defining said base of said slots.
Claim 11
Dependent Claim
40 words
An assembly as claimed in claim 4, said tray including an upstanding web adjacent to each side edge of said base and extending lengthwise of said base, and an inwardly extending rib along the upper edge of each upstanding web.
Claim 12
Dependent Claim
71 words
An assembly as claimed in claim 9, said tray including a web extending downward at each side edge of said base and a rib extending downward from each side edge of said base spaced inward from the downwardly extending webs, the arrangement such that the upstanding webs and inwardly extending ribs of a lower tray can be positioned between the downwardly extending webs and downwardly extending rib of an upper tray.
