Spring lock

Claim 2

In a releasable ski binding device having a locking element and first adjustable means for altering the effective force of a spring, the force of which is to be overcome in order to release said ski binding device, said first adjustable means including adjustable abutment means and first adjusting means for adjusting said adjustable abutment means toward and away from said locking element, said spring being positioned between said adjustable abutment means and said locking element and under a pretension so that the magnitude of the pretension of said spring is altered during an adjustment of said first adjusting means and second adjustable means for altering said effective force of said spring and thereby the force required to release said ski binding device, wherein the improvement comprises means defining a housing for enclosing said first adjusting means and releasably secured cover means for preventing access to the interior of said housing means and said first adjusting means, said housing means and said cover means when connected together defining said second adjustable means for facilitating an adjustment of said effective force of said spring but to a degree less than said first adjusting means.

Claim 3

The improvement according to claim 1, wherein said housing means is coaxial with said first adjusting means and includes means for supporting same for a coaxial reciprocating movement toward and away from said locking element; and operating means on said cover means releasably secured to said housing means for facilitating said adjustment of said effective force of said spring to a degree less than said first adjusting means.

Claim 4

The improvement according to claim 2, wherein said housing means includes means defining an opening coaxial with said first adjusting means; and wherein said cover means includes securing means for securing said cover means in said opening against a relative rotation with respect to said housing means during operation of said operating means.

Claim 5

The improvement according to claim 3, wherein said operating means on said cover means is an operating lever swingably secured to said cover means.

Claim 6

The improvement according to claim 3, wherein said operating means on said cover means is slot means adapteD to receive bladed tool means therein for adjustment of said housing means.

Claim 7

A releasable ski binding device, comprising: base means; a locking element; first adjustable means for altering the effective force of a spring which urges said locking element into a locked position, the force of said spring to become overcome in order to release said locking element and, therefore, said ski binding device, said first adjustable means including a rotatable threaded bolt having a radially extending flange intermediate the ends and an abutment threadedly engaged on said threaded bolt and movable toward and away from said locking means upon a rotation of said threaded bolt to thereby alter said effective force of said spring mounted between said abutment and said locking element; second adjustable means coaxial with said threaded bolt for altering said effective force of said spring and thereby the force required to release said ski binding device, said second adjustable means including a rotatable hollow threaded member the interior of which is adapted to receive one end of said threaded bolt therein, said hollow threaded member being threadedly engaged with said base means and engaged with said flange and adapted to move toward and away from said locking element upon a rotation of said hollow threaded member to effect a movement of said abutment toward and away from said locking element; and releasable cover means releasably secured to said hollow threaded member for preventing access to said interior of said hollow threaded member and access to said one end of said threaded bolt.

Claim 8

A releasable ski binding device, comprising: base means; a locking element; first adjustable means for altering the effective force of a spring which urges said locking element into a locked position, the force of said spring to become overcome in order to release said locking element and, therefore, said ski binding device, said first adjustable means including a rotatable threaded bolt having a radially extending flange intermediate the ends and an abutment threadedly engaged on said threaded bolt and movable toward and away from said locking means upon a rotation of said threaded bolt to thereby alter said effective force of said spring mounted between said abutment and said locking element; second adjustable means coaxial with said threaded bolt for altering said effective force of said spring and thereby the force required to release said ski binding device, said second adjustable means including a rotatable hollow threaded member the interior of which is adapted to receive one end of said threaded bolt therein, said hollow threaded member being threadedly engaged with said base means and engaged with said flange and adapted to move toward and away from said locking element upon a rotation of said hollow threaded member to effect a movement of said abutment toward and away from said locking element; and releasable cover means releasably secured to said hollow threaded member for preventing access to said interior of said hollow threaded member and access to said one end of said threaded bolt.

Claim 9

A releasable ski binding according to claim 6, wherein said cover means includes a swingable operating lever to facilitate a manual rotation of said hollow threaded member.

Claim 10

A releasable ski binding according to claim 6, wherein said cover means includes means defining a slot adapted to receive a bladed tool means therein for facilitating a manual rotation of said hollow threaded member.

Claim 11

A releasable ski binding according to claim 6, wherein said one end of said threaded bolt has means defining a slot therein adapted to receive a bladed tool means therein when said cover means has been removed.
