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 reserve 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: 8
Claim 1
Independent Claim
200 words
A peelable assembly comprising: a pair of adjacent plates, each plate having two ends and two lateral edges, placed so that on lateral edge of one plate faces one lateral edge of the other plate, thus defining a junction between said facing lateral edges; a flexible element placed over said plates so as to cover said junction, said flexible element extending colinearly along said junction and being bound to said plates by a uniform layer of solder extending colinearally to said junction so as to releasably secure said adjacent plates together; a first reserved area without any adhesion to said solder, said first reserved area being provided on a top surface on one end of each said plate, beneath said flexible element; or on a bottom surface of one end of said flexible element so that said first reserved area covers a corresponding end of each said plate; and recesses in said plates at points corresponding to a border between said first reserved area of said surface having said first reserved area and the remaining area of said surface having said first reserved area; whereby, upon removal of said flexible element bound to said plates, said plates are completely released.
Claim 2
Dependent Claim
200 words
A peelable assembly comprising: a pair of adjacent plates, each plate having two ends and two lateral edges, placed so that on lateral edge of one plate faces one lateral edge of the other plate, thus defining a junction between said facing lateral edges; a flexible element placed over said plates so as to cover said junction, said flexible element extending colinearly along said junction and being bound to said plates by a uniform layer of solder extending colinearally to said junction so as to releasably secure said adjacent plates together; a first reserved area without any adhesion to said solder, said first reserved area being provided on a top surface on one end of each said plate, beneath said flexible element; or on a bottom surface of one end of said flexible element so that said first reserved area covers a corresponding end of each said plate; and recesses in said plates at points corresponding to a border between said first reserved area of said surface having said first reserved area and the remaining area of said surface having said first reserved area; whereby, upon removal of said flexible element bound to said plates, said plates are completely released.
Claim 3
Dependent Claim
29 words
A peelable assembly according to claim 1 wherein said first reserved area is provided on a top surface at one end of each said plate, beneath said flexible element.
Claim 4
Dependent Claim
26 words
A peelable assembly according to claim 1 wherein said first reserved area is provided at said bottom surface of said one end of said flexible element.
Claim 5
Dependent Claim
71 words
A peelable assembly according to claim 1 wherein said first reserved area has a peeling initiation end and an opposite end, said peeling initiation end being shaped essentially as an isosceles triangle, portions of said plate or flexible element having said first reserved area which are outside of said isosceles triangle being soldered to said flexible element or plate, respectively, said other end of said first reserved area being essentially rectangular.
Claim 6
Dependent Claim
40 words
A peelable assembly according to claim 2 wherein a second reserved area to which solder does not adhere is provided on a bottom surface of one end of said flexible element, said second reserved area covering said first reserved area.
Claim 7
Dependent Claim
88 words
A peelable assembly according to claim 5, wherein said second reserved area has a peeling initiation end and an opposite end, said opposite end beginning at a portion of said flexible element corresponding to said one end of said plate and extending parallel to said junction up to an unreserved area of said plates, at which place is the base of said peeling initiation end, said peeling initiation end being essentially the shape of an isosceles triangle and covering a portion of said unreserved area of said plates.
Claim 8
Dependent Claim
37 words
A peelable assembly according to claim 4, wherein an end of said plates or said flexible element opposite said end corresponding to said first reserved area has a third reserved area to which no solder can adhere.
