Climbing apparatus

A climbing apparatus, comprising:

• a. an elongated shank having a first end and a second end;
• b. a stirrup having a sole portion and a medial portion extending upward and away from the sole portion, the stirrup being rotatably attached to said shank at the first end thereof such that said stirrup is rotatable about an axis generally normal to said shank, said stirrup sized and configured to be engageable with the footwear of a user;
• c. a plurality of tips attached to a lower surface of said sole portion;
• d. a leg support attached to said shank at the second end thereof;
• and
• e. at least one spike attached to said medial portion of said stirrup such that a centerline through the at least one spike will not be parallel to a centerline through any one of said plurality of tips and rotating the stirrup will move the at least one spike relative to the elongated shank;
• f. said leg support being rotatably attached to said shank;
• and
• g. a transversely mounted spring and pin intermediate said shank and said leg support to provide tilting of said leg support and absorption of forces.

A climbing apparatus, comprising:

• a. an elongated shank having a first end and a second end;
• b. a stirrup rotatably attached to said shank at the first end thereof such that said stirrup is rotatable about an axis generally normal to said shank and rotates in a plane parallel to a plane through a longitudinal axis of said shank, said stirrup having a sole portion and an anterior portion being rotatably connected to said sole portion;
• said stirrup being sized and configured to be engageable with the footwear of a user;
• c. a leg support attached to said shank at the second end thereof and tiltable relative to said shank;
• and
• d. at least one spike attached to said stirrup such that said at least one spike extends outwardly and downwardly at an angle relative to said shank and rotating the stirrup will move the at least one spike relative to the elongated shank.

A climbing apparatus, comprising:

• a. an elongated shank;
• b. a leg support attached to the shank at one location and tiltable relative to said shank;
• c. a stirrup rotatably attached to said shank at a second location spaced from the one location such that said stirrup rotatable about an axis generally normal to said shank and rotates in a plane parallel to a plane through a longitudinal axis of said shank;
• d. a plurality of straps extending from one side of the stirrup to another side of the stirrup for allowing a wearer's foot to be secured to the stirrup;
• and
• e. at least two spikes attached to the stirrup such that each of said at least two spikes extends outwardly and downwardly at an angle relative to said shank and rotating the stirrup will move the at least two spikes relative to the elongated shank and said at least two spikes arranged at spaced locations along a direction defined by the wearer's foot and extending outwardly and downwardly at an inclined angle relative to the shank so that the spikes are able to penetrate into a tree being climbed by the wearer of the climbing apparatus.
