Definitions

• the invention relates to stacks of cassettes and, more particularly, to those of cassettes intended to receive conductors.
• the term “conductors” means both filiform or strip-shaped elements in which light can propagate, in particular optical fibers, as filiform or strip-shaped elements conducting electricity, in particular metallic wires, for example copper or telephone copper wires.
• optical fibers are organized in a stack of cassettes.
• Each cassette generally has a bottom and two side walls.
• a route definition baffle is provided on the bottom and makes it possible to comply with the constraints of minimum radius of curvature of the conductors.
• Each cassette generally has an inlet and an outlet for the conductors laterally.
• a cassette can be kept open at approximately 90 ° C. from the underlying cassette using a hook from a side wall of the upper cassette which comes behind a boss formed on a tab from the edge of the cassette. lower.
• the upper cassette cannot exceed a position of 90 °, by the fact that there are provided, on the two edges facing the two cassettes, stop elements.
• a stack of cassettes of this kind allows the operator to work with his hands free when he opens the cassette, but has the disadvantage of not allowing the opening of the cassette to be carried out at the option of either side of the cassette.
• the invention overcomes this drawback.
• the invention relates to a stack of at least two cassettes articulated two by two and each comprising a bottom and two side walls.
• a first axis extends parallel to one of the side walls and at a distance from it towards the outside and a second axis extends parallel to the other of the side walls and at a distance from it. this outward.
• Each axis is carried by at least one lug from its side wall and shaped so as to define successively, from the side wall outwards, a first recess and a first notch, a second recess and a second notch.
• a removable rigid trigger guard has a fork-finished branch which engages on the first axis (or the second axis) of two adjacent cassettes.
• the tab of a first cassette is arranged relative to a tab of a second cassette adjacent to the first cassette, so that, when the trigger guard is snapped onto the first axes (or second axes) of the two cassettes, the rotation of the first cassette relative to the second cassette around the first axis (second axis) of the first cassette brings the first notch of the leg of the first cassette into the first hollow of the leg of the second cassette and / or the second notch of the tab of the first cassette in the second recess of the tab of the second cassette.
• one of the branches of the trigger guard has a wall substantially parallel to the side wall of the facing cassette.
• the trigger guard can thus not rotate around the axis taken in this branch and the opening movement can be carried out in an integrity manner, the trigger guard being secured to the cassette without degree of freedom in rotation.
• there comes from each side wall a pair of legs the distance between the two legs of the couple being just greater than the width of the trigger guard.
• the trigger guard is thus prevented from sliding along the axis.
• the drawing shows two identical cassettes A lower and B upper.
• Each cassette has a bottom 1 and two opposite side walls 2, 3.
• a baffle 4 of coiling of optical fibers there is formed in the side walls an inlet 5 and an outlet 6 of optical fiber.
• the legs 7 to 9 carry an axis 13 which extends parallel to the side wall 2 and at a distance from it. this.
• the lugs 10 to 12 carry an axis 14.
• Each lug for example the lug 7, successively comprises a first recess 15, a first notch 16 and on a part extending substantially parallel to the wall 2 and perpendicular to the part forming the recess 15 and the notch 16, a second recess 18 and a second notch 19.
• the entire cassette is molded in one piece with the exception of rigid and removable bridges 20 and staples 23 lock.
• Each trigger guard 20 is made up of two branches 21, 22 ended in a fork which can snap into two axes 13a, 13b of two superimposed cassettes, a is a suffix showing that the part concerned is part of cassette A, and b of the cassette B.
• the trigger guard 20 forming a hinge is rigid in the sense that it cannot bend, but the material which constitutes it has sufficient elasticity to allow the forks 21, 22 to be snapped onto the axes 13.
• the fork 22 has a wall 25 substantially parallel to its side wall 2 so that the trigger guard 20 cannot rotate relative to the axis 13a. In however, the axis 13b can rotate in the fork 21.
• Each locking clip 23 has a handle 24 by facilitating the gripping.
• the two cassettes A, B are articulated on this side.
• the upper cassette B is opened, by rotating it with respect to the axes 13b, the first notch 16b comes into the first recess 15a and the second notch 19b comes into the second recess 18a of the underlying cassette.
• the cassette is thus kept at 90 ° in the open position. You can close it by removing the notches from the hollows. If one wants to open the cassette B on this side and articulate it on the other, it suffices to remove the bridges 20 and pass them to the opposite side.
