Definitions

  • ABSTRACT A novel auxiliary ski for physically handicapped persons, comprising a ski runner having a through hole therein, a pair of guide plate members erected from the ski runner, and a pole rotatably supported between the guide plate members.
  • Each guide plate member has a pair of pole locking slots formed at two different positions in the lengthwise direction of the pole, and a guiding slot connecting the pair of pole locking slots.
  • the pole is lockable at one of the pole locking slots and is movable, along the guiding slot, in its lengthwise direction with respect to the ski runner and further lockable at the other of the pole locking slots, whereby the lowermost tip of the pole can either be retained within the through hole of the ski runner or be protruded through said hole down to below the ski runner.
  • This invention relates to an improved ski for the physically handicapped persons, especially for the onelegged or lame persons. More particularly, the invention relates to a crutch-like ski which is used auxiliarily by such persons.
  • the principal object of the present invention is to answer their hopes by proposing a novel ski.
  • Another object of the invention is to provide an improved ski which can be easily used by the physically handicapped persons such as one-legged or lame persons without any difficult training and handling.
  • the ski of the invention comprises a ski runner having a through hole therein, a pair of guide plate members erected from the ski runner, and a pole rotatably supported on the ski runner and between the guide plate members, and movable in its lengthwise direction with respect to the ski runner, each guide plate member having a pair of pole locking slots formed at two different positions in the lengthwise direction of the pole, and further having a guiding slot connecting the pair of pole locking slots, whereby the pole is lockable at one of the pole locking slots and movable, along the guiding slot, in its lengthwise direction with respect to the ski runner and further lockable at the other of the pole locking slots, so that the lowermost tip of the pole can either be retained within the through hole of the ski runner or be protruded through the hole down to below the ski runner.
  • the pole may be given a biasing force by means such as a coiled compression spring interposed between the pole and the ski runner.
  • This ski can be used auxiliarily like a pair of crutches for the lame persons on the snow.
  • the lowermost tip of the pole In the running on a descending slope, the lowermost tip of the pole is retained within or above the through hole to keep the smooth running surface of the ski runner; and when walking on a flat or ascending slope, the lowermost tip of the pole is projected below the through hole without any difficult operation so as to enable a usual sticking operation.
  • FIG. 1 is a vertical side view of an embodiment of the present invention
  • FIG. 2 is a cross-sectional front view of said embodiment showing the relation between the ski runner and the pole;
  • FIG. 3 is also a cross-sectional front view of said embodiment showing the lowermost end of said pole projected below the ski runner;
  • FIG. 4 is a schematic illustration of a man using the skis of the present invention.
  • the numeral 1 denotes the middle portion of a ski runner, to which a pole 2 is attached in the substantially vertical direction through a pair of guide plate members 3 mentioned below in detail.
  • a through hole 4 is formed to receive therethrough the lower portion 5 of said pole 2.
  • the lower most tip of said portion 5 is provided with a ferrule 6, and the upper portion of said pole 2 is provided with an arm ring 7 and a hand grip 8, both of which extend to the forward side of the ski 1, that is, to the left-hand side of FIG. 1.
  • the pole 2 between the arm ring 7 and handgrip 8 is a little inclined to the rear direction and the lower portion 5 of the pole 2 stands vertically upward.
  • the pair of guide-plate members 3 are erected from:
  • a pipe 9 is rotatably supported in the space between the guide plate members 3 by means of sockets 10 fixed to the
  • the lower portion 5 of the pole 2 comprises a shaft 13 inserted in the pipe 9 and slidable therethrough.
  • the shaft 13 is provided with theabove-mentioned ferrule 6 at the lowermost end thereof and has a cutout portion or portion 14 reduced in diameter at the upper section thereof.
  • the cutout portion 14 of the shaft 13 terminates at a flanged uppermost end 15 of the shaft 13.
  • the lower portion 5 of the pole 2 further comprises an intermediate pipe 16, which is telescopically inserted around the pipe 9 and in which the cutout portion 14 of the shaft 13 is encased so as to form a ring-shaped enclosed space or chamber between the cutout portion 14 and the pipe 16.
  • a coiled compression spring 17 which is abutted on the upper edge 18 of the pipe 9 at its lowermost end and on the flanged end 15 of the shaft 13 at its uppermost end.
  • the intermediate pipe 16 extends above the flanged uppermost end 15 of the shaft 13, and a joint 18 is inserted within the upper portion of the pipe 16.
  • the intermediate pipe 16 and the joint 18 is cou-' pled together by means of a pin 19.
  • the point 18 is further connected to a main pipe 20 by a screw 21.
  • the intermediate pipe 16 is provided with internally threaded sockets 22 at its lower portion, the sockets 22 extending toward the guide plate. members 3, respectively.
  • a flanged guide roller 23 Around each socket 22 is rotatably fixed a flanged guide roller 23 by means of an externally threaded screw 24 tightly screwed into the socket 22.
  • Each guide plate member 3 is perforated with an elongated slot 25, which extends at the upper portion of the guide plate member 3, depicting an arc of a circle having a center at the bolt 11, namely, at a pivot of the rotatable pole 2.
  • the guide plate member 3 is further perforated with a slot 26 existing at the lower portion of the guide plate member 3 and shorter than the slot 25.
  • a ski as claimed in claim 1 wherein said pole is locking slots, and so as to be protruded below said ski runner when said uidin means is located within the formed in said ski runner, said pole being positioned so g g as to be above the lower surface of said ski runner when said guiding means is locked within one of said pole 5 other of said pole locking slots.
