Abstract
Abstract A casing having a boot heel engaging means at its front end is pivoted to a connecting member which is mounted on a base. The connecting member comprises a transverse horizontal plane at its front end and a longitudinal bore which lower end is on the same level as the horizontal plane. Within the longitudinal bore a locking member is provided to be urged forwards which has at its front surface a dented portion to engage with a horizontal pin secured to the casing in the boot heel engaging position.

Total Claims: 8
Claim 1
Independent Claim
258 words
A ski boot heel binding comprising, in combination, a base (1) to be attached to a ski; a connecting member (2) mounted on said base (1), said connecting member having a transverse horizontal flat plane (3'') at its front end, and a longitudinal horizontal bore (18) which lower end is substantially on the same level as said flat plate (3''); a casing (9) covering over said connecting member (2) and pivoted thereto to be partially rotatable about a pin 35, said casing having boot heel engaging members (8)(36) at its front end and being adapted to engage or release the boot heel when pivoted about pin 35; a horizontal pin (10) secured to the side walls of said casing adjacent the region of the bore (18) nearest engaging members (8) (36); and a locking member (5) slidably provided within said bore (18) in said connecting member (2), said locking member having a dented portion (4) which upper end is projected beyond a circular locus of said horizontal pin (10), said locking member (5) being normally biased toward the engaging members (8) (36); whereby, normally, said locking member (5) presses the upper side of said horizontal pin (10) by said dented portion (4) to press fit the lower end of said horizontal pin on said flat plane (3'') of said connecting member (2), and, when an abnormal upward thrust is applied to the boot heel, said horizontal pin (10) is disengaged from said dented portion (4) to release the boot heel from said boot heel engaging members (8, 36).
Claim 2
Dependent Claim
258 words
A ski boot heel binding comprising, in combination, a base (1) to be attached to a ski; a connecting member (2) mounted on said base (1), said connecting member having a transverse horizontal flat plane (3'') at its front end, and a longitudinal horizontal bore (18) which lower end is substantially on the same level as said flat plate (3''); a casing (9) covering over said connecting member (2) and pivoted thereto to be partially rotatable about a pin 35, said casing having boot heel engaging members (8)(36) at its front end and being adapted to engage or release the boot heel when pivoted about pin 35; a horizontal pin (10) secured to the side walls of said casing adjacent the region of the bore (18) nearest engaging members (8) (36); and a locking member (5) slidably provided within said bore (18) in said connecting member (2), said locking member having a dented portion (4) which upper end is projected beyond a circular locus of said horizontal pin (10), said locking member (5) being normally biased toward the engaging members (8) (36); whereby, normally, said locking member (5) presses the upper side of said horizontal pin (10) by said dented portion (4) to press fit the lower end of said horizontal pin on said flat plane (3'') of said connecting member (2), and, when an abnormal upward thrust is applied to the boot heel, said horizontal pin (10) is disengaged from said dented portion (4) to release the boot heel from said boot heel engaging members (8, 36).
Claim 3
Dependent Claim
31 words
A ski boot heel binding as claimed in claim 1, wherein each of said locking member (5) and said bore (18) in said connecting member (2) has a circular sectioned shape
Claim 4
Dependent Claim
36 words
A ski boot heel binding as claimed in claim 1, wherein said connecting member (2) mounted upon said base (1) is normally urged forwards by a spring (3) and is movable to the lengthwise direction thereof.
Claim 5
Dependent Claim

A ski boot heel binding as claimed in claim 1, wherein said locking member (5) is provided with an elongated transverse hole (20) through which a pin (21) connects said locking member (5) to said connecting member (2).
Claim 6
Dependent Claim
56 words
A ski boot heel binding as claimed in claim 4, wherein said pin (21) also loosely passes through an elongated hole (22) provided through an end of a L-shaped unlocking lever (7) to pivot it to said connecting member, whereby said lever (7) can retract said locking member (5) against said spring (6) by lowering it.
Claim 7
Dependent Claim
43 words
A ski boot heel binding as claimed in claim 1, wherein the locking member (5) is normally biased by means of a spring (6), one end of which acts on said locking member and the other end of which abuts a plug (19).
Claim 8
Dependent Claim
26 words
A ski boot heel binding as claimed in claim 6, wherein the plug (19) is adjustable to vary the biasing force developed by the spring (6).
