Description

United States Patent 3,058,120 MECHANICAL STlLT Glen D. Smith and Noel W. Smith, both of 4717 N. 2nd St., Abilene, Tex. Filed July 18, 1960, Ser. No. 43,529 1 Claim. (Cl. 34)

This invention relates to a mechanical stilt or pair of stilts, and has as its primary object the provision of an improved stilt construction which may be advantageously employed either as an amusement device, or in any occupation wherein an additional height is necessary or desirable.

A further object of the invention is the provision of a stilt construction which is wholly attached to the leg and foot of the user, thus leaving the hands free for other uses.

A more specific object of the invention is the provision of a stilt which is so designed and arranged as to give perfect balance, and which, by virtue of a pivotal connection and an elongated foot plate, gives substantially the same effect as in walking.

A further specific object of the invention is the provision of a device of this character where the foot piece is arched for the purpose of eliminating falls when stepping on loose objects such as nails, rocks, stones or the like.

A further object of the invention is the provision of such a device wherein the straps on the foot plate may be readily adjusted to fit any type of shoe, thus eliminating permanent mounting.

An additional object of the invention is the provision of such a stilt which is readily adjustable as to height within a predetermined range, such range being normally between 18 and 26 inches, but which may be extended in either direction as desired.

Still another object of the invention is the provision of such a device which, due to the leather cushion connection, gives a substantially noiseless and smooth operation.

Still another object of the invention is the provision of a device which is sturdy and durable in construction, reliable and efiicient in operation, and relatively simple and inexpensive to manufacture, and which may be used by an operator with a minimum of efiort and difliculty.

Still other objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out hereinafter and shown in the accompanying drawing wherein there is disclosed a preferred embodiment of this inventive concept.

In the drawing:

FIGURE 1 is a side elevational view of one stilt according to the instant invention shown as applied to the leg and foot of the user, the latter being indicated in dotted lines, an alternative position of adjustment in use also being indicated in dotted lines.

FIGURE 2 is an end elevational view of the structure of FIG. 1 as viewed from the right.

FIGURE 3 is a sectional view taken substantially along the line 3--3 of FIG. 2 as viewed in the direction indicated by the arrows; and

FIGURE 4 is an enlarged fragmentary detail sectional view showing a constructional element.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Having reference now to the drawing in detail, the stilt of the instant invention is generally indicated at 10, and includes a foot plate 11, which is substantially flat, and of a length to accommodate an average size shoe. The foot plate 11 has an arcuate upwardly extending heel flange 12, and is provided with a toe strap 13, which may be adjustably fitted by means of a buckle 14. The plate 11 may be made of any desired material, such as wood, aluminum, or other suitable metal, and the toe strap 13 is secured to the underside thereof in any desired manner in accordance with the material used.

A pair of spaced lugs 15 depend from the underside of plate 11 at a point adjacent the heel, and are apertured to receive a pivot pin 16, to which is secured a sleeve 17, having a series of perforations 18 therein.

An instep strap 19 is suitably secured to the lugs 15, and extends across the instep of a foot F of the user, as indicated in FIG. 1. Strap 19 is also provided with a buckle 20, which permits suitable adjustment of the device to a variety of shoe sizes.

Front lugs 21 are also provided adjacent the toe of foot plate 11, and have pivotally mounted therein as by means of a pivot 22 a second tubular slevee 23, which is also provided with a seriesof apertures 24. Sleeves 1'7 and 23, respectively, have slidably mounted therein tubular rod members 25 and 26, respectively, which are also apertured as at 27 and 28, the arrangement being such that the sleeves 25 and 26 telescope within the sleeves 17 and 24, and are held in suitably adjusted position by means of cotter pins 29 and 3%, respectively, which extend through selected aligned apertures for adjusting the height of the stilt. Each of sleeves 25 and 26 is pivotally secured as by means of pivots 31 and 32 between pairs of spaced lugs 33 and 34 at the rear and front respectively of a foot plate generally indicated at 35. The foot plate 35 includes a flat rear portion 36 and a flat front portion 37, each of which is provided with a non-slip undersole 38 and 39, respectively, which may be comprised of cork, rubber, leather, or any other desired material. The portions 36 and 37 are connected by an arcuate bridge memher do, the arrangement being such that if the foot members are placed on a loose object, such as a stone or the like, a fall will be precluded, as the arcuate member 40 will be able to bridge the loose object.

Centrally secured to the underside of foot plate 11 is a depending lug 45, which has atfixed thereto a tubular sleeve 46 provided with a series of apertures or openings 47 therein. The securing means for the sleeve 46 may take any desired form such as a bolt or rivet 48. Seated in each end of sleeve 46 is a compression spring 49 and 50, respectively, which springs seat in leather cups 51 and 52, respectively secured to tubular members 17 and 23, at a point closely adjacent the underside of foot plate 11. The inner ends of the springs 49 and 50 are suitably positioned as by means of cotter pins 53 and 54 so that the relative tension of the springs may be adjusted. The cups 51 and 52 may be suitably secured in the sleeves 17 and 23 as by means of self-tapping metal screws 55, for example, although suitable bolts and nuts may be employed if desired.

By virtue of this spring arrangement the stilt is automatically self-aligning, and will return to its initial vertical position after a forward step by the user, during the time when the foot is lifted off the ground. The springs elfectively cushion the movement, and by virtue of the leather cups or washers a relatively smooth and noiseless operation is effected.

Means are provided for securing the device to the leg of the user, and take the form of a tubular post 60 which is provided with suitable apertures 61, which are adapted to be aligned with similar apertures 62 in a sleeve 63 which is pivotally mounted on an extending portion of pivot 31. Sleeve 60 is held in adjusted position relative to sleeve 63 by means of a cotter pin 64, similar to the cotter pins 30 and 31. The sleeve 60 extends outwardly at an angle so that it clears the side of foot plate 11, and extends to a portion adjacent approximately the mid calf of the user. At its upper extremity it is provided with a plate 65 which is secured thereto as by means of bolts 66, the plate being provided with loops or the like through which extends a leg strap 67, provided with a buckle 68, by means of which the strap may be adjusted to fit the leg of the user.

From the foregoing the operation of the device should now be readily understandable. When the foot is first placed on the foot plate 11 the toe strap 13 and instep strap 19 are suitably adjusted. Leg strap 67 is then buckled about the leg, and the device is ready for use, it being understood that obviously a stilt is provided for each foot of the user.

The user then walks in a normal manner, and the pivotal arrangement formed by the pivots 16 and 22, as well as the pivots 31 and 32, permit the user to stride forward in a normal manner, the flexing of the foot portions 36 and 37 about their respective pivots conforming to substantially the normal movement of the foot, such movement being effectively cushioned by the springs 49 and 50, which return the device to normal position during each forward step.

From the foregoing it will now be seen that there is herein provided an improved stilt which accomplishes all the objects of this invention, and others, including many advantages of great practical utility and commercial importance.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative, and not in a limiting sense.
