Definitions

  • a ski binding includes a first member pivotally mounted on a base plate but normally locked in a rest position by means of a manually operable catch.
  • a secondrnernber supporting a boot eng tg ingjaw is connected to the first member by means including a rod extending through central recesses of the two members, the two members having facing bearing surfaces with complementary cross-shaped profiles.
  • a nut on the rod cooperates with a socket on the first member to form a ball-and-socket joint, and a spring urges the second member relative to the rod to hold the second member against the first member, the complementary profiles coacting to hold the second member and jaw in a rest position but allowing release by raising or sideward displacement of the jaw and second member against the action of the spring.
  • An object of the invention is to provide a relatively simple and efficient safety ski binding which enables release in the event of lateral or raising efforts on a boot holding member.
  • a security release mechanism comprising a first member having a first bearing surface and a first recess opening through said first bearing surface, a second member having a second bearing surface and a second recess opening through said second bearing surface, and means for connecting said first and second members together with said first and second surfaces facing one another.
  • Said connecting means include a rod extending through the first and second recesses, means for pivotally connecting said rod to said first member, and spring means for urging said second member relative to said rod towards said first member to hold said first and second bearing surfaces together.
  • the first and second bearing surfaces have complementary profiles coacting together under the action of said spring means for holding said second member in a rest position relative to said first member and for opposing movement of said second member relative to said first member away from said rest position.
  • FIG. 1 is a side elevational view of the binding mounted on a ski
  • FIG. 1a is a schematic side elevational view of the binding in an open position during a forward fall
  • FIG. lb is a schematic side elevational view of the binding in an open position for insertion or voluntary removal of a boot
  • FIG. 2 is a top plan view corresponding to FIG. 1;
  • FIG. 2a is a schematic top plan view corresponding to FIG. 1a, showing the possible lateral displacements in the event of a sideward fall;
  • FIG. 3 is a longitudinal cross-sectional view of the principal members of the binding
  • FIGS. 4a, 4b, 40 show the complementary profiles on the bearing surfaces
  • FIG. 5 is view of a detail seen in cross-section taken along line V-V of FIG. 3.
  • the heel-type safety ski binding shown is carried by a plate 1 fixed at its rear part onto a ski for example by means of a rack 12 enabling it to be adapted to the boot by known means schematically indicated by numerals l3 and 14, and at its central part by two slide pieces 15 and 15a screwed onto the ski.
  • the plate 1 includes on its lateral edges two perpendicular flanges 11 and 11a forming a U-shaped section which supports two spaced-apart transverse shafts l0 and 31.
  • This main body includes a rear part 2 and a central part 4 in which is located a slide 5 to which a stirrup 52 is fixed, the said stirrup 52 carrying a screw 54 which supports a jaw 53 cooperating with a boot heel.
  • a catch 3 cooperating with the rear part 2; this catch 3 enables locking of the binding by engagement in notches 26 provided on the rear face of the rear part 2 (FIG. 1), in which position it is firmly held by the action of a spring 35 disposed in a bottom 34 of the said catch 3.
  • the rear part 2 has a bearing surface 21 and lateral arms 27, 28 through which the shaft 10 passes.
  • the bearing surface 21 is generally perpendicular to the plane of the ski and includes a profile in the shape of a cross with arms of triangular cross-section, these arms being perpendicular and parallel to the said plane.
  • FIG. 4 shows in detail this profile, formed by horizontal arms 22, 24 and vertical arms 23, 25.
  • the central part 4 of the main articulated body is shown in detail in FIG. 3. It is formed by a hollow cylinder closed at its rear end by bearing surfaces 41 having cross-shaped grooves 42, 43, 44, 45 with a profile which is exactly complementary to that of the bearing surface 21 of part 2, so that the said profiles of the two bearing surfaces 21, 41 can interengage in one another in the rest position (FIG. 1) under the pressure of a spring 7 held by a rod 6.
  • the spring 7 is disposed concentric to the said rod 6 and is compressed between a head 61 of rod 6 and the bottom of a cylindrical recess 46 inside the central part 4, i.e., on the face of said wall opposite to surface 41.
  • the rod 6 passes through central openings in the hearing surfaces 21, 41 and has a threaded portion 62 extending through part 2.
  • a nut 9 with a ball or cap-lke surface 91 is screwed on the threaded part 62 of rod 6.
  • the application face 91 of the said nut 9 is received in a corresponding recess in the part 2 in a manner to form a ball-and-socket joint enabling pivoting of the rod 6 and the part 4 accompanied by a co-action of the bearing surfaces 21, 41 which are moved out of their interengaging rest position, against the action of spring 7
  • On the upper wall of the central part 4 is located a threaded bore 47 receiving a screw 48 which limits the path of slide 5.
  • the slide 5 is slidably mounted in the cylindrical recess 46 of the central part 4, and includes an oblong slot 51 in which the end of screw 48 penetrates to limit the path of the said slide 5 along the said slot 51, and to hold the stirrup 52 in a vertical position in relation to the plane of the ski.
  • the slide 5 is pushed outwardly from the free end of part 4 by a spring 8, disposed concentrically about spring 7, inside the cylindrical recess 46 within the central part 4, and has, for example, a hexagonal longitudinal bore (FIG. 5) slidably receiving the hexagonal head 61 of the rod 6 to prevent it from turning during adjustment.
  • a spring 8 disposed concentrically about spring 7, inside the cylindrical recess 46 within the central part 4, and has, for example, a hexagonal longitudinal bore (FIG. 5) slidably receiving the hexagonal head 61 of the rod 6 to prevent it from turning during adjustment.
  • the purpose of the limited sliding movement of the said slide 5 is to absorb deformations of the ski during passages over hollows, and to avoid lamination of fibres which is liable to occur in the long run with modern rigid-soled boots.
  • the stirrup 52 is fixed to slide 5, and comprises a jaw 53 the height of which can be adjusted by means of screw 54 in a manner to embrace the boot heel (not shown) between the said jaw 53 and pedal 55 of stirrup 52.
  • the stirrup 52 includes a vertical part 56 against which is applied, for all degrees of adjustment, the rear face 57 of jaw 53, so that the said jaw cannot pivot in the event of an abnormal force, otherwise than by the displacement of part 4 relative to part 2 about the bearing surfaces 21, 41 by pivoting of rod 6 and body 4 about the ball-and-socket joint.
  • the stirrup 52 is welded to the slide 5 and is received in a mortise 49 provided in the central part 4.
  • the dimensions of the said mortise 49 do not allow the stirrup to pivot about a horizontal axis, but allow to-and fro movement of the stirrup 52 with slide 5.
  • the described safety heel binding operates in the following manner, it being understood that a fixed, nonarticulated stop is fixed on the ski to enable the support of the boot toe.
  • central body 4 is of square or circular (as shown) cross-section in the region of the bearing surfaces 21, 41, opening can take place in three directions: upwards and to the right and left, with an equal releasing effort in the three directions, providing of course that the four arms of the cross-shaped profile all have the same shape.
  • cross-shaped profiles with arms of the same length but different cross-sectional shape.
  • Another possibility is to provide complementary profiles with horizontal branches of an assymetric shape such as to lightly hold the jaw and main body in a raised position following a forward fall, and vertical branches of a shape such as to always automatically return the binding to its initial position after lateral release.
  • a simplified form of the release mechanism could be incorporated in a toe binding.
  • a security release mechanism comprising a first member having a first bearing surface; means defining a first recess in said first member, said first recess opening through said first bearing surface; a second member having a second bearing surface; means defining a second recess in said second member, said second recess opening through said second bearing surface; means for connecting said first and second members together with said first and second surfaces facing one another, said connecting means including a rod extending through said first and second recesses, means for pivotally connecting said rod to said first member, and spring means for urging said second member relative to said rod towards said first member to hold said first and second bearing surfacs together; and means defining on said first and second bearing surfaces complementary profiles coacting together under the action of said spring means for holding said second member in a rest position relative to said first member and for opposing movement of said second member relative to said first member away from said rest position.
  • said second member includes a free end opposite to said second bearing surface, said second recess extending from said bearing surface towards said free end and defining a longitudinal direction of said rod, and further comprising a boot-sole engaging jaw, means for mounting said jaw on said free end of said second member for a limited sliding movement along the longitudinal direc' tion of said rod, and second spring means for urging said jaw in said longitudinal direction outwardly from said second end.
  • a binding according to claim 2 comprising a base plate, means for pivotally mounting said first member on said base plate about an axis parallel to the plane of said base plate, and means for selectively holding said first member in first and second position relative to said base plate, in which first position said first bearing surface is perpendicular to the plane of said base plate, and in which second position said first bearing surface is inclined in relation to the plan of said base plate.
  • said connecting means includes means for universally pivotally connecting said rod to said first member.
  • said connecting means includes means for universally pivotally connecting said rod to said first member
  • said complementary profiles on said first and second bearing surfaces consist of a cross having protruding arms of trianglar cross-section on one of said first and second bearing surfaces and a complementary cross having recessed arms of triangular cross-section on the other of said first and second bearing surfaces, said crosses being centered about the respective openings of said first and second recesses with the arms of said crosses disposed parallel to and orthogonal to said axis of pivoting of said first member on said base plate.
  • said means for selectively holding said first member comprise a leverpivotally mounted on said base plate, a spring urging said lever in a first direction into abutment with said first member, said lever lockably engaging with said first member under the action of said spring when said first member is in its first position and releasably holding said first member under the action of said spring when said first member is in its second position, and means for manually moving said lever against the action of said spring out of locking engagement with said first member in said first position.
