Description
- 1. Technical Field
- This invention relates generally to the field stilts. More particularly, this invention provides for an apparatus and method for adjusting the height of stilts.
- 2. Related Art
- Often it is desirable to reach a desired elevated height through the use of stilts. For example construction workers and other skilled craftsman frequently use stilts to attach fasteners, suspend a ceiling, hang drywall sheeting or access suspended ceiling structures and related electrical, heating, ventilation and air conditioning structures which may be provided therein. Typical stilts are designed to be securely and comfortably attached to the legs/feet of the stilt wearer. Moreover various stilts incorporate component configurations that allow a stilt wearer to maneuver in a manner that incorporates flexure and movement of stilt the elements in order to provide greater stability during use. Known stilts are adjustable and designed to be worn on each leg of a wearer. Often known stilts include a floor platform and a shoe platform which are connected by two parallel spring-loaded pivotally mounted vertical members. Furthermore, hollow tubular leg supports are attached to the vertical members. Straps are provided for attaching stilt leg support elements to a user's leg and for attaching the ankle area and the toe area of the shoe to the shoe platform. Because the vertical members of some common stilts are pivotally attached to the upper shoe platform and the lower floor platform and are spring-loaded, the vertical members are maintained in a substantially parallelogram configuration. This permits stilt users to walk readily on the stilts while maintaining balance.
- In addition, known stilts often employ designs which facilitate height adjustment capability since desired reach elevations may vary depending upon the size and stature of the stilt wearer and the height of the objects desired to be reached. Common stilts often include means for extending or compressing stilt height by adjusting the position of vertical stilt members with respect to other stilt components. For example some known stilts include hollow vertical members that slidably receive other components that can be securely positioned at various heights with respect to the vertical members. Common stilts can be adjusted to be taller or shorter by positioning and fastening ordinary height adjustment components accordingly. However, in several instances the height adjustment capability of common stilts falls short of the elevation needed to be reached by a stilt wearer even when the known stilts are extended and adjusted to be as tall as the adjustable components will allow. This renders the stilts ineffective in providing the height advantage desired by the user. Accordingly, the user is required to either reach the desired elevation in a manner other than through the use of stilts such as by utilizing scaffolding, or by obtaining a different set of taller stilts.
- Accordingly, there is a need in the field stilts for an improved apparatus and method for a stilt height adjustment apparatus that provides a user with the ability to reach desired elevations without the need to obtain and use separate taller stilts or resort to inconvenient non-stilt elevation remedies.
- The present invention provides an apparatus and method for stilt height adjustment that offers improved reliability.
- A first general aspect of the invention provides a stilt height adjustment apparatus for a stilt having a pivotally movable parallelogram frame structure being partitionable into a top portion including spaced apart vertical strut members extending toward a pivotally connected horizontal shoe platform and a bottom portion including spaced apart vertical strut members extending toward a pivotally connected horizontal floor platform, said stilt height adjustment apparatus comprising: a spaced pair of connected substantially vertical supports, said vertical supports configured to removably attach between the top portion and bottom portion of the stilt, wherein the removable attachment of the spaced pair of vertical supports of the stilt height adjustment apparatus increases the height of the stilt by vertically extending the pivotally movable parallelogram frame structure.
- A second general aspect of the invention provides an improvement in a stilt apparatus having a resiliently pivotally movable parallelogram frame structure being separable into a top segment including spaced apart vertical strut members extending toward a pivotally connected horizontal shoe platform and a bottom segment including spaced apart vertical strut members extending toward a pivotally connected horizontal floor platform the improvement comprising the provision, intermediate the shoe platform and the floor platform but adjacent to the top spaced apart vertical strut members and bottom spaced apart vertical strut members, of a height adjustment component being formed to detachably couple the top segment into operable position with the bottom segment while maintaining resilient pivotal movement ability of the parallel frame structure and adjustably increase the height of the stilt.
- A third general aspect of the invention provides a stilt height adjustment method comprising: separating a top portion of a stilt having spaced apart vertical strut members extending toward a pivotally connected horizontal shoe platform from a bottom portion of a stilt having spaced apart vertical strut members extending toward a pivotally connected horizontal floor platform; providing a height adjustment apparatus including a spaced pair of substantially vertical supports, said vertical supports configured to removably attach between the top portion and bottom portion of the stilt; and coupling the top portion into operable higher position with the bottom portion by detachably affixing the spaced pair of substantially vertical supports of the height adjustment apparatus to the spaced apart vertical strut members of the top and bottom portions of the stilt.

height adjustment apparatus 10 may be configured to removably attach between thetop portion 232 andbottom portion 234 of thestilt apparatus 200, wherein the removable attachment of the spaced pair of vertical supports 20 a-b of the component stilt height adjustment apparatus may increases the height of thestilt apparatus 200 by vertically extending the pivotally movableparallelogram frame structure 230. Moreover the componentheight adjustment apparatus 10 may be provided, intermediate theshoe platform 204 and thefloor platform 206 but adjacent to the top spaced apartvertical strut members vertical strut members height adjustment apparatus 10 may be formed to detachably or removably couple or attach thetop portion 232 or segment of thestilt apparatus 200 into operable position thebottom portion 234 or segment while maintaining resilient pivotal movement ability of theparallel frame structure 230. Further still, the component height adjustment apparatus may adjustably increase the height of thestilt 200. - The vertical strut members 222 a-b and/or 224 a-b of the
stilt 200 may include at least one or a plurality of vertically spacedholes 228. Moreover, each of the vertical supports 20 a-b of the componentheight adjustment apparatus 10 may include at least one or a plurality of vertically spacedholes 28 corresponding toholes 228 on the vertical strut members of the stilt. In addition, further includedfastener components 250 may interact with the plurality ofholes 28 of the vertical support members 20 a-b and the correspondingholes 228 of the vertical struts 222 a-b and 224 a-b of thestilt apparatus 200 to facilitate telescopically adjustable attachment of the vertical supports 20 a-b of the componentheight adjustment apparatus 10 to thestilt apparatus 200. - Referring further to
FIGS. 1-6 , thestilt apparatus 200 may include a dampingspring assembly 275, which may have upper and lower dampingsprings 270 a and 270 b affixed to the rearvertical strut 222 b and arigid actuator arm 276 which extends from the frontvertical strut 222 a to a medial position between thesprings 270 a and 270 b. The dampingspring assembly 275 may nominally bias thestilt device 200 to theparallelogram shape 230. For instance, the dampingspring assembly 275 may provide flexibility to a stilt user by permitting limited forward and rearward pivoting of the verticals struts 222 a-b and 224 a-b with respect to theshoe platform 204 during maneuvering by the user. In addition, theresilient member 70 of the component stiltheight adjustment apparatus 10 may be operably connected to the spaced pair of substantially vertical supports 20 a-b for cushioning and restricting pivotal motion of theparallelogram frame structure 230. Theresilient member 70 andcorresponding spring assembly 75 of the componentheight adjustment apparatus 10 may work in conjunction with the dampingspring assembly 275 to maintain spacing in theparallelogram structure 230 and dampen pivotal movement of the parallelogram structure. - Still further, the

A distal end of theouter sleeve 286 may support the clam-shell assembly 290 to support a user's leg at a position just below the user's knee. The lateral extent and relative angle of thesupport 282 with respect to theshoe platform 204 may be adjustable using thesupport attachment assembly 240. It is envisioned that during normal usage a user will typically wear twosuch stilt devices 200, with one being attached to each leg. The twostilt devices 200 will generally be configured in a mirrored fashion so that thesupport 282 extends along the outside of each leg. Thus, it will be understood that thestilt device 200 shown in the drawings is a “right-footed” version, and the corresponding “left-footed” version has been omitted for simplicity of discussion. - A stilt height adjustment method is now described with reference to
FIGS. 1-6 . The method may include separating atop portion 232 of astilt 200 having spaced apart vertical strut members 222 a-b extending toward a pivotally connectedhorizontal shoe platform 204 from abottom portion 234 of astilt 200 having spaced apart vertical strut members 224 a-b extending toward a pivotally connectedhorizontal floor platform 206. For example, a user may unfastentypical fasteners 250, such as bolts and wing nuts, of thestilt 200 to partition the previously assembly top andbottom portions height adjustment apparatus 10 including a spaced pair of substantially vertical supports 20 a-b, said vertical supports 20 a-b configured to removably attach between thetop portion 232 andbottom portion 234 of thestilt 200. - Furthermore, the stilt height adjustment method may comprise coupling the
top portion 232 into operable higher position with thebottom portion 234 by detachably affixing the spaced pair of substantially vertical supports 20 a-b of the componentheight adjustment apparatus 10 to the spaced apart vertical strut members 222 a-b and 224 a-b of the top andbottom portions stilt apparatus 200. The higher position of thetop portion 232 is thus obtained by the insertion of the componentheight adjustment apparatus 10 into theparallelogram frame structure 230 of the reassembledstilt apparatus 200. - With continued reference to
FIGS. 1-6 , additional depiction of astilt 200 height adjustment method is further described wherein detachably affixing the spaced pair of substantially vertical supports 20 a-b of the componentheight adjustment apparatus 10 to the spaced apart vertical strut members 222 a-b and 224 a-b of the top andbottom portions stilt 200 includes insertingfasteners 250, such as bolts, through theholes 28 of the vertical supports 20 a-b and corresponding vertical struts 222 a-b and 224 a-b and tightening wing nuts onto the bolts to secure the componentheight adjustment apparatus 10 between the top andbottom portions - Further methodology for stilt height adjustment may include, maintaining resilient pivotal movement ability of the
parallel frame structure 230 formed by coupling thetop portion 232 into higher operable position with thebottom portion 234 by detachably affixing the componentheight adjustment apparatus 10 therebetween. For example, thespring assembly 75 of the componentheight adjustment apparatus 10 may act, in conjunction with the dampingspring assembly 275 of thestilt 200, to preserve resilient movement and dampen the pivotal action of theparallelogram structure 230. Hence, a use may use thestilt 200 having the component height adjustment apparatus attached and still enjoy the freedom and security of pivoting parallelogram type support. - While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the embodiments of the invention as set forth above are intended to be illustrative, not limiting. Various changes may be made without departing from the spirit and scope of the invention as defined in the following claims.
