摘要 The invention discloses a pair of stilt boots, incrementally vertically adjustable, whereby the operator, by foot movement, can selectively release the spring urged latched foot plates attached to his respective left and right feet, to raise or lower them by selective weight shift and foot pressure control. Each boot mainly comprises a boot housing or latch lug positioner or support providing vertically spaced apart latch means under which a step plate, to which a foot of the operator is attached, may be latched in increments of vertical adjustment.
权利要求
1. A pair of elevationally adjustable stilt boots, each comprising a base, latch support means upstanding therefrom, a spring yieldably upstanding adjacent said support means, a latching foot step plate upon top of said spring, connection means for connecting the foot of an operator on top of said plate, incrementally vertically spaced apart latch means carried by said support means and adapted, selectively, to hold said plate in selectively latched position, whereby upon the application of operator foot pressure downwardly and with side twist, said plate is unlatched for desired change in incremental elevation, with spring torsion entering upon ease upon side plate in return of said plate to latched position.
2. A method of selectively incrementally adjusting the working position of an operator comprising the operator standing upon a pair of steps, each above yieldably, releasably latchable, side twistable means, applying increased foot pressure and foot side twist to release the steps, one after the other into side twisted, released position for elevationally incremental change in elevation, with yieldable counter side twist occurring in achieving step releasably latched, selected position.
3. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which the springs for the respective boots are fabricated in lefts and rights.
4. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which the latch means comprise a plurality of angularly spaced apart, elevationally aligned latch lugs at a plurality of incrementally vertically spaced apart positions.
5. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which said latch support means comprises a housing.
6. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which each boot additionally includes elevational spacer means below said base.
7. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which said connection means for connecting the foot of an operator on top of said plate comprises foot strap means.
8. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which said latch support means provide an open front before said spring, step plate and latch means.
9. A pair of elevationally adjustable stilt boots as claimed in claim 1 in which said spring provides an upper and lower anchor prong, and in which said step plate and said base, respectively, provide hole to receive said anchor prongs therein.
10. A method as claimed in claim 2 in which yieldable counter side twist may abet said spring torsion in returning said plate to latched position.
