DETAILED DESCRIPTION

[0018] The telemark ski binding assembly 20 of the present disclosure has a toe retainer 22 and a lock assembly 24. The lock assembly has an actuator assembly 26. The lock assembly 24 is coupled to the toe retainer 22. An operator can adjust the lock assembly 24 from being in a first configuration, unlocked configuration (See FIGS. 1-3 showing lock assembly in the unlocked configuration), to being in a second configuration, locked configuration. See FIGS. 4-7 showing lock assembly in the locked configuration. The operator can also adjust the lock assembly from being in the second configuration to being in the first configuration. The toe retainer, when the lock assembly is in the first configuration, unlocked configuration, is itself unlocked and in a touring mode. Thus, placing the lock assembly in the unlocked configuration from the locked configuration unlocks the toe retainer. The toe retainer 22 when unlocked is unrestrained from rotating (pivoting) relative to a base 44. Thus, when an operator takes steps, the toe retainer rotates (pivots) relative to the base 44 along and with a first rotating radius. The first radius has a center point 28 which is a pivot point. The point is a center point and pivot of rotation of the toe retainer.

[0019] The toe retainer 22 when the lock assembly 24 is in the second configuration, locked configuration, is restrained from rotating (pivoting). The toe retainer is itself locked and in the ski mode. Thus, placing the lock assembly in the locked configuration from the unlocked configuration locks the toe retainer. (See FIGS. 4-7 showing the toe retainer locked). Preferably the toe retainer 22 when locked is restrained from rotating (pivoting) more than a negligible amount, relative to the base. Most preferably it is fully restrained from rotating (pivoting), relative to the base 44, when locked.

[0020] As explained in more detail below, an operator can adjust the lock assembly 24 to the locked configuration from the unlocked configuration by adjusting an actuator 30 of the actuation assembly 26 to a second position, down position 32, from a first position, up position 34. Adjusting the actuator 30 to the second position 32 places a latch 36 of the lock assembly 24 and a catch 38 of the lock assembly 24 into an interference position with respect to one another. See FIG. 4. When in the interference position, the latch 36 and catch 38 cooperate to restrain the toe retainer 22 from rotating (pivoting) relative to the base. Preferably the toe retainer is fully restrained from rotating (pivoting) relative to the base 44.

[0021] A heel retainer 40 is coupled to the toe retainer 22. A coil spring 42 biases the heel retainer 40 against rotating relative to the toe retainer 22. The bias restrains the heel retainer 40 from rotating, relative to the toe retainer 22, when the toe retainer is unlocked and can rotate (pivot) relative to the base 44. Thus, when the toe retainer 22 is unlocked, and an operator takes steps, the toe retainer 22 and heel retainer 40 will both rotate together in unison substantially inline along and with first rotating radius and around the first center point 28. The heel retainer remains substantially rotationally fixed in place relative to the toe retainer 22. On the other hand, when the toe retainer 22 is locked and is restrained from rotating (pivoting), the heel retainer 40 will rotate, relative to the toe retainer 22 and base 44. It will rotate with and along a rotating second radius around a second center point 46. The radius has the second center point 46 which is a second pivot point. The second center point 46 is a center point of rotation of the heel retainer.

[0022] The second point 46 is at a different location than the first point 28. Thus, when the toe retainer 22 is locked, and an operator takes steps, the heel retainer 40 will rotate relative to the toe retainer 22 and the base 44 around the second center point 46 which is different from the first center point 28. The toe retainer is restrained from rotating (pivoting) relative to the base 44.

[0023] In more detail, the toe retainer 22 has an upper portion 22a, side portions 22b, 22b and a bottom portion 22c, 22c. The upper portion 22a, side portions 22b, 22b and a portion 22c of the bottom portion 22c, 22c form a seamless toe cage 22a, 22b, 22b, 22c. The bottom portion 22c, 22c of the toe retainer, in addition to the portion 22c forming the cage, includes a central bottom portion 22c. The bottom portion 22c forming the cage laterally bounds the central bottom portion 22c. The side portions 22b, 22b of the toe retainer include lateral boot supporting sections 22b and lateral coupling sections 22b. The lateral boot supporting sections 22b provide lateral boot support. The lateral coupling sections 22b seamlessly carry the catch 38 and receive a first coupling 48 which pivotally couples the toe retainer 22 to the base 44. The lateral coupling sections 22b also receive a second coupling 50 which pivotally couples the toe retainer 22 to a knuckle 62 whose import is explained more fully below. The lateral coupling sections 22b also receive a support 52 which resists movement of a portion of the coil spring 42 which is carried by the second coupling 50.

[0024] The following explains in more detail how the heel retainer 40 is coupled to the toe retainer 22 and biased by the coil spring 42. The heel retainer 40 is fixedly coupled to a rear case 54. The rear case 54 is slideably coupled to a pair of main tubes 56. The rear case slides over the tubes 56 in the first 58 and second 60 longitudinal directions when an operator telemark skis. The rear case 54 is coupled to a pair of compression springs (not shown) which bias the rear case 54 towards the first longitudinal direction 58. One compression spring is in each main tube 56. The pair of main tubes 56 are fixedly coupled to the knuckle 62. The second coupling 50 is received in the knuckle 62 and pivotally couples the knuckle 62 to the toe retainer 22 lateral sections 22b and thus rotationally couples the heel retainer 40 to the toe retainer 22.

[0025] The coil spring 42 biases the knuckle 62 against rotating (pivoting) relative to the toe retainer 22. The bias restrains the knuckle 62 from rotating (pivoting), relative to the toe retainer 22, when the toe retainer 22 is unlocked and rotates (pivots) relative to the base. Thus, when the toe retainer 22 is unlocked, and an operator takes steps, the toe retainer 22, knuckle 62, main tubes 56, rear case 54, and heel retainer will all rotate together in unison, inline along and with the first radius around first center point 28. On the other hand, when the toe retainer 22 is locked and is restrained from pivoting relative to the base, the knuckle 62, main tubes 56, rear case 54, and heel retainer 40 will all rotate together in unison and inline along and with the second radius around the second center point 46, relative to the toe retainer and base. Thus, when the toe retainer is locked and therefore unable to pivot, and an operator takes steps, the knuckle 62, main tubes 56, rear case 54, and heel retainer 40 will all rotate together, in unison and inline along and with the second radius around the second center point 46, relative to the toe retainer and base.

[0026] The base 44 carries at least a portion of the lock assembly 24. The lock assembly 24 comprises the actuator assembly 26, the latch 36, and the catch 38. The actuator assembly 26, in addition to the actuator 30 comprises a linkage assembly 64 which couples the actuator 30 to the latch 36. The linkage assembly 64 includes a first pin 64a which is received by the actuator 30. The first pin 64a is coupled to the base 44 by a first link 64b. The first link 64b is rotatable relative to the first pin 64a and the base 44. The linkage assembly includes a second pin which is received by the actuator. The second pin 64c is slideably coupled to the base 44 through an elongated opening 65 in the base 44. The actuator 30 is coupled to the second pin 64c. The second pin 64c is coupled to a spring support 64d which carries a compression spring 64e. The compression spring 64e is between an end 64d of the spring support and a first end 64f of a second link 64f. A second end 64f of the second link 64f is coupled to the latch 36. An extension spring 64g couples the second link 64f to the base 44 and biases the second link 64f in a position which places the latch 36 outside of the catch 38 opening. The catch 38 and latch 36 are in a non-interfering position relative to one another when the latch is outside of the catch. In the non-interfering position, the toe retainer 22 is unlocked, and the lock assembly 24 is in the unlocked configuration.

[0027] To adjust the lock assembly 24 from the unlocked configuration to the locked configuration, the actuator 30 is moved from the up first position 34 to the down second position 32 by an operator. Before rotating the actuator 30 to the down position 32, the actuator 30 is first moved forward in the first longitudinal direction 58 carrying the second pin 64c, spring support 64d, compression spring 64e, second link 64f and latch 36 forward in the first longitudinal direction 58 against the bias of the extension spring 64g. The latch 36 and second link 64f are moved forward with the actuator 30 until the latch 36 contacts an abutment portion 38 of the catch 38. The contact prevents further movement of the latch 36 and second link 64f forward in the first direction 58. The actuator 30, however, can be further moved forward in the first longitudinal direction 58 and rotated down below center. The further movement and rotation below center carries the second pin 64c away from the second link 64f in the first longitudinal direction 58 and carries the spring support 64d through the second link first end 64f in the first longitudinal direction 58. The further forward movement and rotation compress the compression spring 64e. The lock assembly 24 and toe retainer 22 are locked after the further forward movement and rotation below center. Link 64b when rotated below center is at an angle 67 greater than 180 degrees with the base 44.

[0028] To adjust the lock assembly 24 from the locked configuration to the unlocked configuration, the actuator 30 is moved from the down second position 32 to the up first position 34 by an operator. Rotation, of the actuator 30 up also moves the actuator rearward in the second longitudinal direction 60. After rotation upward, the extension spring 64g pulls the actuator further in the second longitudinal direction 60 carrying the second pin 64c, spring support 64d, compression spring 64e, second link 64f and latch 36 in the second longitudinal direction 60. The latch 36 and second link 64f are moved in the second direction 60 by the extension spring 64g until the latch 36 contacts an abutment portion 65 defining the elongated opening 65 of the base 44. The contact prevents further movement of the latch 36 and second link 64f in the second direction 60. The latch 36 is outside of the catch opening 38. The catch 38 and latch 36 are in a non-interfering position relative to one another. In the non-interfering position, the toe retainer 22 is unlocked, and the lock assembly 24 is in an unlocked configuration.

[0029] The base 44 carries a ski break assembly. The break assembly comprises a ski beak 66 and a coil spring 68. The ski break 66 comprises break wire 66a coupled to a break mover 66b, and claws 66c coupled to the break wire 66a. The coil spring 68 is carried by the break wire and abuts up against a portion of the base 44. The ski break 66 is adjustable between a breaking position (ski break down, see FIG. 4) and a ski position (ski break up, see FIG. 5). The coil spring 68 biases the break 66 in a breaking position. In the breaking position, the break mover 66b is in an up position, see FIG. 4. In the up position, a portion of the break mover 66b is further above the toe retainer bottom 22c, 22c then when the ski break 66 is in the skiing position. Also, the beak wire 66a and break claws 66c extend further downward in a vertical position as compared to when the break 66 is in the skiing position. The break mover 66b has break mover extensions 66b, which couple with toe retainer bottom extensions 22e. The bottom extensions 22e couple to the break mover extensions 66b when the toe retainer is rotated up relative to the base. The coupling moves the break mover 66b down as the toe retainer is rotated up.

[0030] The heel retainer 40 comprises a bottom 40a, lateral side supports 40b, a clip 40c, and a clip lock 40d. The clip 40c is coupled to the lateral side supports 40b and spring loaded with a coil spring to be biased in an unclipped position, see FIG. 4. A heel of a boot pushes the clip 40c into a clipped position, see FIG. 5, when the boot is coupled to the binding. The clip lock 40d is placed in the locking position, see FIG. 5, to lock the clip 40c into the clipped position. In the locking position the clip lock upper 40d is oriented to engage a clip upper 40c.
