Abstract
Abstract A method is provided of temporary assembling by soldering of peel off plates through soldering material and a flexible junction element for a mechanical release device to release two parts temporarily fixed edgewise by peeling off the flexible element and the soldering material. There is provided on the plates and flexible junction element reserved areas without any adherence to the soldering material, and preferably at the limits of said reserved areas, a recess for removing any excess of soldering material, and the melting solder material is put under load for distributing it between the plates and the flexible junction element. A so obtained assembly can be applied particularly to obtain automatic opening of containers in particular in space for spreading out solar panels.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
236 words
A method of temporarily assembling by soldering releasable plates with soldering material and a flexible junction element, said plates belonging to a mechanical release device for releasing two parts temporarily fixed edgewise to one another, said plates being adapted to be respectively brought edge by edge onto adjacent edges of said parts, the soldering material being disposed on the plates and the flexible junction element being applied onto said soldering material, there being provided a means for causing under the action of a mechanism automatic progressive lifting of said flexible element, the arrangement of said means being such that, on actuation of the mechanism, the flexible element peels off the soldering material, thereby provoking complete release of the temporarily fixed parts as the flexible element is totally removed therefrom, said assembling method comprising the steps consisting of: providing on the plates and the flexible junction element reserved areas without any adherence to the soldering material for delimiting connection areas between such plates and such flexible element, providing in the plates recess means adapted to collect any excess of soldering material and interposing and then melting the soldering material between the plates and the flexible junction element, and then putting the melted soldering material under load so as to distribute said soldering material between the plates and the flexible junction element, but outside of the reserved areas, with the recess means collecting any excess of soldering material.
Claim 2
Independent Claim
236 words
A method of temporarily assembling by soldering releasable plates with soldering material and a flexible junction element, said plates belonging to a mechanical release device for releasing two parts temporarily fixed edgewise to one another, said plates being adapted to be respectively brought edge by edge onto adjacent edges of said parts, the soldering material being disposed on the plates and the flexible junction element being applied onto said soldering material, there being provided a means for causing under the action of a mechanism automatic progressive lifting of said flexible element, the arrangement of said means being such that, on actuation of the mechanism, the flexible element peels off the soldering material, thereby provoking complete release of the temporarily fixed parts as the flexible element is totally removed therefrom, said assembling method comprising the steps consisting of: providing on the plates and the flexible junction element reserved areas without any adherence to the soldering material for delimiting connection areas between such plates and such flexible element, providing in the plates recess means adapted to collect any excess of soldering material and interposing and then melting the soldering material between the plates and the flexible junction element, and then putting the melted soldering material under load so as to distribute said soldering material between the plates and the flexible junction element, but outside of the reserved areas, with the recess means collecting any excess of soldering material.
Claim 3
Dependent Claim
27 words
A method as in claim 1, wherein the soldering material is provided as gauged soldering wires disposed in parallel to the edges of said temporarily fixed parts.
Claim 4
Dependent Claim
22 words
A method according to claim 1, wherein said reserved areas are obtained by depositing a composition of zinc, nickel and molybdenum oxides.
Claim 5
Dependent Claim
20 words
A method according to claim 1 wherein said reserved areas extend up to the adjacent edge portions of said plates.
Claim 6
Dependent Claim
19 words
A method according to claim 1, wherein reserved areas are provided at each end of the flexible junction element.
Claim 7
Dependent Claim
42 words
A method according to claim 1, wherein the flexible junction element has a peeling initiation end and an opposite end, a reserved area being provided at the peeling initiation end of a triangular shape having an apex directed to said opposite end.
Claim 8
Dependent Claim
23 words
A method according to claim 1, wherein some of the recess means are provided at the limit of some of the reserved areas.
Claim 9
Dependent Claim
38 words
A method according to claim 1, wherein the putting under load of the melting soldering material is realized by two weights disposed side by side and resting on the flexible junction element through a metallic load distribution plate.
Claim 10
Dependent Claim
32 words
A method according to claim 8 wherein several pairs of adjacent plates are temporarily fixed by soldering, with two adjacent plates of differing pairs being loaded by one and the same weight.
