Definitions

  • This invention relates generally to stilts and to an improvement in the construction and design of the historic stilt.
  • the invention While simple in design, the invention is considered up ⁇ scale in design and construction quality.
  • the overall design and construction is with rounded corners and hidden or padded hardware and corners, with concealment of protrusions/sharp edges and snag points such that no sharp corners, edges or obstacles are exposed that might injure.
  • the ability to adjust the height of the invention, quickly and easily without tools, increases the utility of the invention.
  • the step is formed so as to wrap around the pole portion of the invention providing a griping action on the pole, thereby integrating the step and pole, reuslting in increased strength and safety of the invention.
  • the wrap around design of the step allows the use of a clevis pin or detent pin instead of nut and bolt to fasten the step to the pole.
  • pins instead of nuts and bolts, means that no tools are required to adjust the height of the stilt.
  • the time required to adjust the stilt is reduced to a minimum. This greatly enhances the utility of the stilt to the user.
  • the adjusting mechanism of the invention step uses a cle ⁇ vis pin and ring, or a detention pin, which are both safe and quick to remove for adjusting the height. Height adjustment is accomplished by constructing the vertical pole portion of the invention of two round tubes, one of which is smaller in diameter and fits within the bottom of the upper or outside pole.
  • the upper (outside) pole has a hole through it that is lined up with holes in the lower (inside) pole at the desired height.
  • a clevis pin or detent is pushed through the gripping side of the step, through the upper pole hole, through two holes on the lower pole of the same elevation at the desired height, through the hole in the opposite side of the upper pole, and then through the horizontal receiving hole in the step.
  • This invention is designed with the intention that both children and adults would use them. They key elements con ⁇ sidered in the design of this invention are: (A) safety, (B) a height adjustment mechanism that is easy to operate, (C) durability, (D) strength, (E) light weight and (F) an up-scale look.
  • FIG. 1 is a prospective view of the stilt.
  • FIG. 2 is a front and side view of the stilt.
  • FIG. 3 is a exploded view showing all the parts of the stilt.
  • FIG. 4 is a top plan view of the step of the stilt.
  • FIG. 5 is a front elevational view of the step of the stilt.
  • FIG. 6 is side elevational view of the step of the stilt. DETAIL DESCRIPTION OF THE DRAWINGS
  • FIG. 1 shows a stilt having a upper pole (3) and a lower pole (4).
  • the lower pole (4) fits into the upper pole (3).
  • a protective soft cap (2) is placed over the top end of the upper pole (3).
  • a rubber foot (8) is placed on the bottom of the lower pole (4) to provide traction while walking on the stilts as well as protection from any sharp edges around the bottom of the lower pole (4).
  • a molded step (5), of light weight material, is shown attached to the upper pole (3) by a clevis pin (6) and held in place by a ring or cotter pin (alternatively the step (5) can be held in place by a detention pin which does not require a cotter pin).
  • Step (5) is designed with a vertical foot brace (11) to prevent the upper pole (3) and lower pole (4) from rotating on their axis while being used, increasing the uti ⁇ lity and safety of the stilt.
  • the top of the step (5) has a tread design to increase the traction for the user's foot.
  • FIG. 2 shows a front and side view of the stilt.
  • FIG. 3 shows an exploded view of the parts of the stilt.
  • FIGS. 4-6 illustrate top, front, and side views, respec ⁇ tively, of the step 5 of the stilt.
  • the vertical foot brace (11) prevents the upper pole (3) and lower pole (4) from rotating on their axis while being used, increasing the utility and safety of the stilt.
  • the top of the step has a tread design (12) to increase the traction for the user's foot. These features eliminate the necessity for the use of any type of straps, lips or other gimmicks which can entangle the user's foot thus increasing the safety of the stilt.
  • the molded design (13) of the step around the upper pole (3) adds strength and stability to the step and allows the use of a quick connect pins instead of nuts and bolts. Although nuts and bolts could still be used.

Abstract

L'invention concerne une échasse réglable composée d'un premier (3) et d'un second (4) élément tubulaire, ledit second élément tubulaire étant agencé de manière à coulisser avec ledit premier élément. Lesdits éléments tubulaires comportent des trous adaptés (9, 10) pour recevoir une vis à ÷illet ou un autre dispositif adéquat (6) empêchant le mouvement longitudinal relatif entre les premier et second éléments tubulaires. On a prévu un échelon (5) à proximité de la partie inférieure du premier élément tubulaire, doté d'une partie de montage s'engageant dans le premier élément tubulaire, d'une partie supérieure horizontale (12) destinée à supporter le pied de l'utilisateur, ainsi qu'une partie verticale (11) calant le pied, au contact du côté du pied de l'utilisateur, afin d'empêcher que l'échelon ne pivote par inadvertance.
