Abstract
Abstract An apparatus for the elastic, resilient mounting of the non-switching magnet part of an electromagnetic switching device in the direction of the magnetic force thereof, comprising a ring-shaped leaf spring which is closed in itself. More particularly, the leaf spring is arranged so as to rest against the non-switching magnet part at at least two contact areas and to rest against parts fixed relative to the housing at two further contact areas, the latter contact areas being situated on the side of the leaf spring opposite from the side resting upon the former two contact areas.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
Apparatus for use in the elastic, resilient mounting of a non-switching magnet part of an electromagnetic switching device to the base plate thereof and in the direction of the magnetic force thereof comprising: a ring-shaped leaf spring which is closed in itself; at least two contact areas provided on said magnet part upon which a first side of said spring rests; and members fixed relative to the housing of said device which provide two further contact areas upon which the side of said spring opposite said first side rests.
Claim 2
Dependent Claim
89 words
Apparatus for use in the elastic, resilient mounting of a non-switching magnet part of an electromagnetic switching device to the base plate thereof and in the direction of the magnetic force thereof comprising: a ring-shaped leaf spring which is closed in itself; at least two contact areas provided on said magnet part upon which a first side of said spring rests; and members fixed relative to the housing of said device which provide two further contact areas upon which the side of said spring opposite said first side rests.
Claim 3
Dependent Claim
35 words
Apparatus in accordance with claim 1 in which: said magnet part includes a stack of laminations and extensions of said laminations; and said contact areas provided by said magnet part are formed on said extensions.
Claim 4
Dependent Claim
38 words
Apparatus in accordance with claim 1 in which: said magnet part includes a cover sheet and tabs which are bent out from said sheet; and said contact areas provided by said magnet part are formed on said tabs.
Claim 5
Dependent Claim
14 words
Apparatus in accordance with claim 3 in which said spring has a rectangular shape.
Claim 6
Dependent Claim
46 words
Apparatus in accordance with claim 4 in which: the distance of said spring from said sheet is larger than the width of the spring; and said contact areas are arranged and shaped in such a manner that said spring can be detached by lateral displacement thereof.
Claim 7
Dependent Claim
24 words
Apparatus in accordance with claim 1 in which: the portions of said spring near said contact areas provided on said magnet part are offset.
Claim 8
Dependent Claim
50 words
Apparatus in accordance with claim 6 in which: said contact areas provided on said magnet part are at an angle which deviates from the normal to direction of motion of said part and which approximately corresponds to the position of said portions at half the operational travel of said spring.
Claim 9
Dependent Claim
42 words
Apparatus in accordance with claim 1 which further includes: an intermediate damping layer disposed between said magnet part and said base plate, said layer having tufts which engage said base plate and extended members which fix the position of said magnet part.
Claim 10
Dependent Claim
31 words
Apparatus in accordance with claim 1 in which: said base plate has tabs which are bent off therefrom; and said members fixed relative to the housing are formed by said tabs.
Claim 11
Independent Claim
113 words
A method of securing a ring-shaped leaf spring to a mounting apparatus, said apparatus being of a type which is used to mount a non-switching magnet part of an electromagnetic switching device to the base plate thereof and in the direction of the magnetic force thereof and which includes said spring, at least two contact areas provided on said magnet part upon which a first side of said spring rests and tabs bent off from said base plate which provide two further contact areas upon which the side of said spring opposite said first side rests, comprising the step of: bending said tabs into operating position after said spring is positioned and tensioned.
