Abstract
Abstract A braking device for a ski to stop its eventual escaping, comprising a braking unit adapted to be moved, due to an unexpected separation of ski and ski-boot, from a resting position flush with the ski trunk into a braking position by spring action, in which position a member of the braking unit projects beyond the sliding surface of the ski trunk in a transverse direction thereto, the braking unit being releasably held in resting position by a disengageable release element preventing the spring action only in engaged position and being disengageable by the separation of ski and ski-boot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
227 words
A braking device for stopping the escape of a ski, comprising a base piece mounted on an upper side of the ski; a pivot fixed in said base piece and projecting upwards therefrom; a braking unit including a support member pivotally mounted on said pivot and a braking member hinged to said support member and adapted to lie thereon in resting position and to be displaced into a braking position wherein said braking member projects downwardly beyond the sliding surface of the ski, first spring means connected between said support member and said braking member for resiliently urging the latter into said braking position, a catch retaining said braking member in resting position against the action of said first spring means, second spring means connected between said base piece and said support member for resiliently urging the latter to an operative position permitting said braking member to move to said braking position, and a stop on said base piece for maintaining said support member against movement to said operating position under the urging of said second spring means; a releasing element normally engaging and maintaining said braking member against displacement to said braking position; and means connected with said releasing element and operative for withdrawing said releasing element from such contact only in response to an unintended separation of the ski and the ski-boot from each other.
Claim 2
Dependent Claim
227 words
A braking device for stopping the escape of a ski, comprising a base piece mounted on an upper side of the ski; a pivot fixed in said base piece and projecting upwards therefrom; a braking unit including a support member pivotally mounted on said pivot and a braking member hinged to said support member and adapted to lie thereon in resting position and to be displaced into a braking position wherein said braking member projects downwardly beyond the sliding surface of the ski, first spring means connected between said support member and said braking member for resiliently urging the latter into said braking position, a catch retaining said braking member in resting position against the action of said first spring means, second spring means connected between said base piece and said support member for resiliently urging the latter to an operative position permitting said braking member to move to said braking position, and a stop on said base piece for maintaining said support member against movement to said operating position under the urging of said second spring means; a releasing element normally engaging and maintaining said braking member against displacement to said braking position; and means connected with said releasing element and operative for withdrawing said releasing element from such contact only in response to an unintended separation of the ski and the ski-boot from each other.
Claim 3
Dependent Claim
26 words
A braking device as claimed in claim 1, wherein said releasing element is positioned between said stop and one of said members of said braking unit.
Claim 4
Dependent Claim
27 words
A braking device as claimed in claim 1, wherein said means comprises a pulling member adapted to be connected to the skI-boot or leg of the skier.
Claim 5
Dependent Claim
34 words
A braking device as claimed in claim 1, wherein said releasing element is a ball-like body, and said braking unit in resting position resiliently projects into the path of disengagement of said releasing element.
Claim 6
Dependent Claim
30 words
A braking device as claimed in claim 1, wherein said releasing element is a ring-like body which, in resting position of said braking unit, is engaged by said braking member.
Claim 7
Dependent Claim
33 words
A braking device as claimed in claim 1, wherein said catch is a permanent magnet device mounted on said support member and said braking member, respectively, for maintaining the latter in resting position.
Claim 8
Dependent Claim
33 words
A braking device as claimed in claim 1, wherein said catch is a snap-bolt device mounted on said support member and said braking member, respectively, for resiliently maintaining the latter in resting position.
Claim 9
Dependent Claim
61 words
A braking device as claimed in claim 1, wherein said catch is a resilient pawl formed by said stop, said braking member having a pin-like projection engaged by said pawl for resiliently maintaining said braking unit in resting position, and said releasing element being a ring removably placed on said projection for disengaging the latter from said pawl and said stop.
Claim 10
Dependent Claim
53 words
A braking device as claimed in claim 1, wherein said catch is a rigid wall portion of said base piece which engages said braking member in resting position, and buffer means arranged between said support member and said braking member and compressed by the latter in the resting position of said braking unit.
Claim 11
Dependent Claim
46 words
A braking device as claimed in claim 1, a resilient pawl being mounted at the bottom side of said support member and engaging said braking member adjacent to its hinged end in braking position against any outer force counteracting the force of said first spring means.
