A releasable riser plate assembly is provided for use with a telemark binding. The assembly is mounted to a ski. The assembly includes a base plate interconnecting a front and rear housing, and a release plate mounted over the base plate. Force transmitting members are integrated in the housings to hold the release plate. A toe adapter of the telemark binding is mounted on the release plate. The toe of a ski boot is secured in the toe adapter. Adequate force generated by the boot in either a lateral direction or vertical direction results in disengagement of the release plate from the base plate and housings. Accordingly, the boot separates from the ski. The assembly incorporates a ski brake. The ski brake activates upon separation of the release plate. The release plate is reattached by a step-in motion wherein a front portion of the release plate is positioned under a lip of the front housing, and then the heel of the boot is pressed down against the ski to seat a rear portion of the release plate against the base plate and rear housing.

What is claimed is: 1. A releasable riser plate assembly adapted for use in a Telemark ski binding, said riser plate assembly comprising: a substantially planar base plate; a front housing connected to a front end of the base plate, said front housing having a front spring mounted therein, and a front force transmitting member associated with said front spring for transmitting a force from the front spring; a rear housing connected to a rear end of the base plate, said rear housing having a rear spring mounted therein, and a rear force transmitting member associated with said rear spring for transmitting a force from the rear spring; a release plate mounted over the base plate; a ski brake positioned between the base plate and said release plate; and a flange integral with said front housing, wherein a front edge of said release plate is received in a gap between said base plate and said flange, and wherein a rear edge of said release plate contacts said rear housing; wherein, said front and rear force transmitting members each have portions thereof that are exposed through respective orifices formed in said front and rear housings; and said release plate includes a groove formed on said rear edge thereof, and said exposed portion of said rear force transmitting member being received in said groove when said release plate is mounted over said base plate. 2. An assembly, as claimed in claim 1, wherein: said ski brake includes a pair of lateral extensions that extend beyond lateral sides of said base plate and said release plate. 3. An assembly, as claimed in claim 1, wherein: each said force transmitting member includes a spherical shaped member. 4. An assembly, as claimed in claim 1, further including: a front housing screw communicating with said front spring for adjusting said spring; and a rear housing screw communicating with said rear spring for adjusting said rear spring. 5. An assembly, as claimed in claim 1, wherein: said ski brake is biased such that release of said release plate with respect to said base plate causes said ski brake to move from a first planar position to a second non-planar position. 6. An assembly, as claimed in claim 1, wherein: said front edge of said release plate includes a pair of notches formed thereon. 7. An assembly, as claimed in claim 1, wherein: said rear edge of said release plate includes a rounded protrusion formed thereon. 8. An assembly, as claimed in claim 1, wherein: said rear edge of said release plate has a rounded protrusion formed thereon, and said groove being formed in said rounded protrusion. 9. An assembly, as claimed in claim 1, wherein: said release plate is substantially planar. 10. An assembly, as claimed in claim 1, wherein: said base plate has a depression formed therein for receiving said ski brake. 11. An assembly, as claimed in claim 1, wherein: said ski brake includes a shaped wire member having a pair of extensions, a pair of supports, and an interconnecting part for interconnecting said pair of supports, said interconnecting part being biased with respect to said pair of supports such that said interconnecting part urges said pair of extensions to a non-planar position with respect to a plane of the riser plate assembly. 12. An assembly, as claimed in claim 1, wherein: said release plate has a groove formed on an upper surface thereof. 13. An assembly, as claimed in claim 1, wherein: said rear housing includes a concave contact surface, and said rear edge of said release plate has a convex shaped protrusion which is received in said concave surface when said release plate is mounted over said base plate. 14. A method of providing controlled release of a ski boot attached to a ski by means of a ski binding, said method comprising the steps of: providing a ski binding which attaches the boot to the ski, said binding including a toe adaptor for receiving a toe of the boot, a cable extending from the adaptor and placed around the boot, and a heel locking mechanism operable with said cable to secure the binding to the boot; providing a releasable riser plate assembly including a base plate, a release plate mounted over the base plate, and a ski brake positioned between the base plate and the release plate; causing a force to be applied to the boot wherein the toe of the boot is forced in a direction laterally away from a longitudinal axis of the ski to which the boot is attached; disengaging a front surface of the release plate with respect to the base plate in response to the force applied; separating the release plate from the base plate after the release plate is disengaged from the base plate; activating the ski brake in response to separation of the release plate from the base plate, wherein the ski brake moves from a planar position to a non-planar position wherein a portion of the ski brake extends below a lower surface of the ski; and constraining a rear edge of said release plate from movement in a lateral direction with respect to a longitudinal axis of the ski. 15. A ski binding assembly comprising: (i) a toe adaptor for receiving a toe of a ski boot, said toe adaptor including means for capturing a toe portion of the ski boot; (ii) a cable secured to said toe adaptor, said cable being placed around a periphery of the boot, said cable including at least one spring biased member interconnecting adjacent ends of the cable; (iii) a heel locking mechanism secured to said cable and adapted for engaging a heel portion of the ski boot; (iv) a riser plate assembly comprising: (a) a substantially planar base plate; (b) a front housing connected to a front end of the base plate, said front housing having a front spring mounted therein, and a front force transmitting member associated with said front spring for transmitting a force from the front spring; (c) a rear housing connected to a rear end of the base plate, said rear housing having a rear spring mounted therein, and a rear force transmitting member associated with said rear spring for transmitting a force from the rear spring; (d) a release plate mounted over the base plate, said release plate having a relief formed on a front edge thereof and a groove formed on a rear edge thereof, the front force transmitting member engaging the relief and the rear force transmitting member engaging the groove; (e) a ski brake positioned between the base plate and said release plate; and (f) a flange integral with said front housing, wherein a front edge of said release plate is received in a gap between said base plate and said flange, and wherein a rear edge of said release plate contacts said rear housing. 16. A releasable riser plate assembly adapted for use in a Telemark ski binding, said riser plate assembly comprising: a substantially planar base plate; a front housing connected to a front end of the base plate, said front housing having a front spring mounted therein, and a front force transmitting member associated with said front spring for transmitting a force from the front spring; a rear housing connected to a rear end of the base plate, said rear housing having a rear spring mounted therein, and a rear force transmitting member associated with said rear spring for transmitting a force from the rear spring; a release plate mounted over the base plate; a ski brake positioned between the base plate and said release plate; and a flange integral with said front housing, wherein a front edge of said release plate is received in a gap between said base plate and said flange, and wherein a rear edge of said release plate contacts said rear housing; and said front and rear force transmitting members each have portions thereof that are exposed through respective orifices formed in said front and rear housings.
