Claim 3

The combination as defined in claim 1, wherein said connection elements are arranged both neighboring said toe portion as well as said heel portion of the ski boot sole.

Claim 4

The combination as defined in claim 2, wherein the sole is provided with recess means neighboring said toe portion of the ski boot sole, said cooperating connection elements comprising blocking body means arranged at said intermediate portion of the ski boot sole and guided for movement in the lengthwise direction thereof, spring means for loading said blocking body means, said connection elements further including locking element means secured to the ski, said blocking body means engaging with said locking element means.

Claim 5

The combination as defined in claim 3, further including a common adjustment mechanism for adjusting the boundary load of said locking element means.

Claim 6

The combination as defined in claim 4, wherein said adjustment mechanism is accessible from the underface of the sole.

Claim 7

The combination as defined in claim 4, wherein the adjustment mechanism is accessible from the top surface of the ski.

Claim 8

The combination as defined in claim 4, wherein the adjustment mechanism comprises two jaw members serving as spring countersupports, and cam disk means for adjusting the spacing between said jaw members.

Claim 9

The combination as defined in claim 7, wherein at the front and rear of said sole there is provided a respective pair of blocking body means, said spring means being supported at an associated one of said cam disk means.

Claim 10

The combination as defined in claim 2, wherein said cooperating connection elements comprise locking element means arranged at the ski boot sole neighboring the toe portion and the heel portion thereof, said cooperating connection elements further comprising blocking body means arranged at the top surface of the ski for movement in the lengthwise direction thereof, and spring means for loading said blocking body means.

Claim 11

The combination as defined in claim 9, further including a common adjustment mechanism for adjusting the boundary load of said locking element means.

Claim 12

The combination as defined in claim 10, wherein said adjustment mechanism is accessible from the underface of the ski boot sole.

Claim 13

The combination as defined in claim 10, wherein said adjustment mechanism is accessible from the top surface of the ski.

Claim 14

The combination as defined in claim 10, wherein said adjustment mechanism comprises two jaw members serving as spring countersupport, and cam disk means for adjusting the spacing between said jaw members.

Claim 15

The combination as defined in claim 13, wherein a respective pair of blocking body means are arranged at the front and rear of said sole, said spring means being supported at an associated one of said cam disk means.

Claim 16

The combination as defined in claim 2, wherein said connection elements comprise magnetic plate members.

Claim 17

The combination as defined in claim 15, wherein said magnetic plate members comprise permanent magnets.

Claim 18

The combination as defined in claim 16, further including means for exchangeably securing said permanent magnetic plate members to the ski.

Claim 19

The combination as defined in claim 15, wherein the said magnetic plate members comprise at least one ferromagnetic plate member.

Claim 20

The combination as defined in claim 18, wherein the ferromagnetic plate member is embedded in a recess provided at the ski boot sole.

Claim 21

The combination as defined in claim 1, wherein said toe or heel portions, due to their compressibility, allow the transfer of release forces from said boot to said connecting elements more directly during a vertical pivotal boot release by providing no substantial resistance to the pivotal movement, and also facilitates walking when said boot is released from said ski.

Claim 22

A ski boot embodying a ski boot sole having a toe portion and a heel portion, an intermediate sole portion formed of essentially rigid material arranged between said toe portion and said heel portion, said toe portion and said heel portion of said ski boot sole being formed of an elastic compressible material, a first type of connection element means located at the ski boot sole and intended to cooperate with a second type of connection element means arranged at a ski associated with the ski boot for providing a releasable connection between the ski boot and the ski, said ski boot sole including a bottom tread surface, said first type of connection element means being arranged at the region of the rigid intermediate sole portion and cooperating with said second type of connection element means through said bottom tread surface of the ski boot sole wherein said toe or heel portions, due to their compressibility, allow the transfer of release forces from said boot to said connecting elements more directly during a vertical pivotal boot release by providing no substantial resistance to the pivotal movement, and also facilitates walking when said boot is released from said ski.

Claim 23

A ski boot embodying a ski boot sole having a toe portion and a heel portion, an intermediate sole portion formed of essentially rigid material arranged between said toe portion and said heel portion, said toe portion and said heel portion of said ski boot sole being formed of an elastic compressible material, a first type of connection element means located at the ski boot sole and intended to cooperate with a second type of connection element means arranged at a ski associated with the ski boot for providing a releasable connection between the ski boot and the ski, said ski boot sole including a bottom tread surface, said first type of connection element means being arranged at the region of the rigid intermediate sole portion and cooperating with said second type of connection element means through said bottom tread surface of the ski boot sole wherein said toe or heel portions, due to their compressibility, allow the transfer of release forces from said boot to said connecting elements more directly during a vertical pivotal boot release by providing no substantial resistance to the pivotal movement, and also facilitates walking when said boot is released from said ski.
