Abstract

A safety stilt for users requiring extended access to overhead or elevated surfaces has two slidably mated shells able to be adjusted to a variety of heights. Foot attachment means are attached to a top surface on the upper shell and a base defines a greater surface area than the surface area defined by the top surface.

Claims

exact text as granted — not AI-modified
1 . A safety stilt, comprising:
 a. a first shell defining a vertical axis and a horizontal axis, a top surface and a base, the top surface having a lesser surface area than an area defined by the base;   b. a second shell defining a vertical axis and a horizontal axis, a top surface and a base, the top surface having a lesser surface area than an area defined by the base, wherein the top surface of the second shell is sized and shaped to be slidably received within the base of the first shell, allowing the second shell to move along the vertical axis of the first shell;   c. height adjustment means allowing the relative position between the first shell and the second shell along the vertical axis to be securely adjusted; and   d. releasable foot attachment means attached to the first shell allowing a user's foot to be secured to the top surface, wherein the foot attachment means will release from the safety stilt if the user falls.   
   
   
       2 . The safety stilt of  claim 1  wherein the first shell and second shell are substantially identical. 
   
   
       3 . The safety stilt of  claim 1  wherein a raised ridge extends above the top surface of the first shell. 
   
   
       4 . The safety stilt of  claim 4  wherein the raised ridge extends partially around the top surface of the first shell. 
   
   
       5 . The safety stilt of  claim 4  wherein the raised ridge extends around a heel end and around both sides, terminating before a toe end of the first shell. 
   
   
       6 . The safety stilt of  claim 1  wherein a plane defined by the base is substantially parallel with the plane defined by the top surface. 
   
   
       7 . The safety stilt of  claim 1  wherein the height adjustment means comprise spaced apertures through the first shell and the second shell, capable of receiving a securing fastener there through. 
   
   
       8 . The safety stilt of  claim 1  wherein the releasable foot attachment means comprise a strap assembly attached to the first shell by a release fastener. 
   
   
       9 . The safety stilt of  claim 1  wherein the first shell and second shell are made of a non-conducting material. 
   
   
       10 . The safety stilt of  claim 9  wherein the first shell and second shell are made of a plastic material. 
   
   
       11 . The safety stilt of  claim 1  wherein a wall extends between and vertically separates and supports the top surface from the base. 
   
   
       12 . The safety stilt of  claim 11  wherein the wall surrounds and extends between the top surface and the base. 
   
   
       13 . A safety stilt, comprising:
 a. a first shell defining a vertical axis and a horizontal axis, a top surface and a base, the top surface having a lesser surface area than an area defined by the base, and a wall extending between and connecting the top surface and the base;   b. a second shell defining a vertical axis and a horizontal axis, a top surface and a base, the top surface having a lesser surface area than an area defined by the base and a wall extending between and connecting the top surface and the base, wherein the second shell is sized and shaped to be slidably received within the base of the first shell, allowing the top surface of the second shell to move along the vertical axis of the first shell;   c. a rib defining an outer surface, extending away from the wall of the first shell and a rib defining an outer surface, extending away from the wall of the second shell, the rib of the first shell further defining an inner surface corresponding with the outer surface such that the outer surface of the rib of the second shell slidably mates with the inner surface of the rib of the first shell;   d. height adjustment means allowing the relative position between the first shell and the second shell along the vertical axes of the first and second shells to be securely adjusted; and   e. releasable foot attachment means attached to the first shell, allowing a user's foot to be secured to the top surface, which will release from the safety stilt if the user falls.   
   
   
       14 . The safety stilt of  claim 13  wherein the first shell and the second shell are made of a non-conducting material. 
   
   
       15 . The safety stilt of  claim 14  wherein the first shell and the second shell are made of plastic. 
   
   
       16 . The safety stilt of  claim 13  wherein the first shell and second shell are substantially identical. 
   
   
       17 . The safety stilt of  claim 13  wherein a raised ridge extends above the top surface of the first shell. 
   
   
       18 . The safety stilt of  claim 17  wherein the raised ridge extends partially around the top surface of the first shell. 
   
   
       19 . The safety stilt of  claim 18  wherein the raised ridge extends around a heel end and around both sides, terminating before a toe end of the first shell. 
   
   
       20 . The safety stilt of  claim 13  wherein a plane defined by a perimeter of the base of the second shell is substantially parallel with a plane defined by the top surface of the first shell when the first shell and the second shell are assembled to form the safety stilt. 
   
   
       21 . The safety stilt of  claim 13  wherein the height adjustment means of the first and second shells comprises spaced apertures capable of receiving a securing fastener there through. 
   
   
       22 . The safety stilt of  claim 13  wherein the releasable foot attachment means comprise a strap attached to the first shell by a release fastener. 
   
   
       23 . The safety stilt of  claim 13  wherein the wall substantially surrounds and extends between the top surface and the base. 
   
   
       24 . The safety stilt of  claim 23  wherein the wall of the first shell tapers outward between the perimeter of the top surface and the base and the wall of the second shell tapers outward between the perimeter of the top surface and the base.
