Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
167 words
A device for positioning and retaining optical fibers in a "horizontal" layer, said device including: a channel-section base, defining a "horizontal" web, and two side flanges projecting from said web, at least one of said side flanges being provided with a slot having a "vertical" first segment of width substantially the same as the diameter of said fibers, which first segment is open at a top end of the flange, the top end being the end opposite from said web, and a "horizontal" second segment of height substantially the same as said diameter and of length adapted to positioning said fibers side-by-side in a layer; a grooved guide member extending between said side flanges and facing the horizontal segment of each slot, and having a groove aligned with said horizontal segment, and being of width that is the same as the length of the horizontal segment, and retaining means for retaining said fibers in a layer, which means are hinge mounted to close on said grooved surface.
Claim 2
Independent Claim
167 words
A device for positioning and retaining optical fibers in a "horizontal" layer, said device including: a channel-section base, defining a "horizontal" web, and two side flanges projecting from said web, at least one of said side flanges being provided with a slot having a "vertical" first segment of width substantially the same as the diameter of said fibers, which first segment is open at a top end of the flange, the top end being the end opposite from said web, and a "horizontal" second segment of height substantially the same as said diameter and of length adapted to positioning said fibers side-by-side in a layer; a grooved guide member extending between said side flanges and facing the horizontal segment of each slot, and having a groove aligned with said horizontal segment, and being of width that is the same as the length of the horizontal segment, and retaining means for retaining said fibers in a layer, which means are hinge mounted to close on said grooved surface.
Claim 3
Dependent Claim
120 words
A device according to claim 1, wherein each side flange provided with said slot includes firstly a "bottom" portion formed directly on said web, a free top face of the bottom portion constituting a reference surface on which the horizontal segment of the slot is delimited, and secondly a pair of guide blocks, the two blocks being mounted and retained side-by-side and not touching each other on said reference surface, and co-operating to delimit the vertical segment of said slot between them, at least one of said guide blocks having a bottom recess open at an "inner" face thereof which is situated facing the other guide block, which recess delimits the horizontal segment of said slot on said reference surface.
Claim 4
Dependent Claim
48 words
A device according to claim 2, wherein said pair of guide blocks is chosen from sets of pairs of blocks, that are interchangeably mounted on said reference surface, and that are used to obtain individual slots of dimensions adapted to said fibers to be positioned in a layer.
Claim 5
Dependent Claim
25 words
A device according to claim 2, wherein the blocks in each pair and said reference surface include complementary means for holding said blocks in place.
Claim 6
Dependent Claim
52 words
A device according to claim 2, wherein each slot includes an enlarged entrance for inserting an individual fiber, which entrance extends said vertical segment up to the top end of its side flange, and is delimited by a bevelled end portion on a small inner face of one of the guide blocks.
Claim 7
Dependent Claim
28 words
A device according to claim 2, wherein, when the blocks are in place on said reference surface, one of said blocks is substantially higher than the other block.
Claim 8
Dependent Claim
50 words
A device according to claim 2, wherein each one of the blocks in each pair includes a bottom end shoulder extending each block's outer face which is opposite from said inner face, and said bottom portion has two end notches receiving the bottom shoulders of the pair of guide blocks
Claim 9
Dependent Claim
26 words
A device according to claim 1, wherein said grooved guide member is constituted by a "top" face of a support mounted and retained on said web.
Claim 10
Dependent Claim
34 words
A device according to claim 8, wherein the top face of said support is recessed and receives a grooved plate removably and interchangeably mounted on said support, said groove being formed in said plate.
Claim 11
Dependent Claim
53 words
A device according to claim 8, wherein the retaining means are a cover that is hinge mounted parallel to said groove on a "rear" edge of said support, which cover cooperates with said support to form a clamp for retaining said fibers in a layer, said clamp being removably mounted on said base.
Claim 12
Dependent Claim
81 words
A device according to claim 10, wherein said cover is equipped with a catch for locking said cover closed on said support, which catch is secured to a "front" edge of the cover and can be snap-fastened under the corresponding front edge of said support, and wherein said support is equipped with a lever for unlocking said snap-fastened catch, which lever is pivotally mounted in said support facing said catch and can be operated from the "front" edge of said support.
Claim 13
Dependent Claim
15 words
A device according to claim 1, wherein the slot in each side flange is L-shaped.
Claim 14
Dependent Claim
21 words
A device according to claim 1, wherein the slot in each side flange is in the shape of an inverted T.
