This invention relates to an improved stilt.
One of the objects of my invention is to provide a stilt which may be quickly elongated or shortened by the user thereof while walking thereon.
Another object ofV the invention is to provide a stilt employing a stirrup which is capable of ready adjustment and which will be released automatically upon pressure upon the latch employed.
A further object of the invention is toprovide a device of this character employing an upper section which is removably connected with the main stilt body employed so that the stilt may be taken down for convenient shipment.
As a further object, the invention seeks to provide a stilt wherein the stirrup will be covered with a readily removable rubber pad so that the device may be used with the utmost comfort.
And as a still further object, the invention seeks to provide a stilt employing compact and highly efficient elongating structure which may be operated with the greatest facility and which will not chafe the legs of the user or otherwise annoy him.
Further objects of the invention, not mentioned hereinbeiore, will Vappear as the description proceeds.
My invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a side elevation of my improved stilt,
Figure 2 is an enlarged detail vertical sectional View, partly in elevation, showing the' step and stirrup structure, with stirrup release mechanism, 35 employed,
Figure 3 is a horizontal sectional View on the line 3-3 of Figure'Z', looking in the direction indicated by the arrows,
Figure 4 is an enlarged detail vertical sec- 40- tional view showing` the elongating structure,
Figure 5 is a horizontal sectional'view on theY line 5-5 of Figure 4,
Figure 6 is a fragmentary verticalV 'sectional View, partly in elevation, showing a portion ofthe elongating structure, and
Figure 7 is a Vertical sectional view of a slightly modified construction wherein the Shanks employed are pressed from sheet metal.
Referring now to the drawings, wherein similar numerals of reference indicate like parts throughout the various views, the numeral I indicates generally a stilt body which is of tubular formation. The stilt body is formed of light weight material and is formed, near its lower end with an integral step 2. As best seen in Figures 2 and 3 of the drawings, the step is formed with atop wall 3 and side reinforcing webs 4 and 5 which dene beneath said bottom wall, a housing 6, the purpose of which will be described in more detailhereinafter. A brace l, of tubular formation, is formed integrally on the body I and extends obliquely upwardly. The brace 'I is at its upper end turned upwardly to define a straight tubular side portion 8 which lies in aparallel plane with the main stilt body, but is, of course, spaced therefrom. The tubular side portion 8 has integrally con-v nected thereto the topvwall 3 and the webs 4 and 5 so that the stilt body I, the step 2, and the brace 1 will all be in one piece. In actual manufacture, the entire structure above described will preferably be cast.
The stilt body I, at the junction thereof with the inner end of the step 2`is formed with a thickened reinforcing portion 9 on which are formed lugs defining a yoke I0.
Swingingly connected with vthe yoke lll is a stirrup strap I I which is preferably formed of `resilient metal. The strap is rolled at its inner end to provide a bearing I2 which journals a trunnion I3 in the yoke I0. It will thus be seen that the stirrup strap II is mounted for slight swinging movement in the yoke l0.
The free end of the strap I I is twisted and bent to define a straight U-shaped portion i4 which is formed with rack teeth I 5.V The U-shaped portion I4 is adapted to extend'into the open upper end of the side portion 8, which side portion has a guide I6 mounted therein. The guide I5 is formed with an opening II therein which is disposed to confront the interior of the housing G.
In order to: provide a cushion for the stirrup strap II so that it will fit comfortably over the toe portion of a shoe, I employ a sleeve I8 of elastic material. Cemented to the sleeve I8 is a preferably sponge rubber cushion I9.
As best seen in Figure 2 of the drawings, the side portion 8 has lstruck'in portions 2li at its lower end. These portions 20 define stops 2l limiting the downward movement of a spring 22 which is mounted in the tube. The spring 22 has a follower 23 mounted thereabove, yand said follower normally engages the lower end of the U- shaped portion I4. When the portion I4 is in its lowermost position, the spring will be compressed, as shown in Figure 2.
Mounted in the housing B is a latch 24 whichy is formed with a pawl 25 removably engageable with the rack teeth I5. The latch 24A is pivotally mounted n the housing by means of a pin 26 which extends through said latch at substantially' finger-engaging portion 21. A spring 28, which is fastened to the under side of the wall 3, engages behind a shoulder 29 on the latch and retains the pawl normally in engagement with one of the rack teeth I5. When the finger-engaging portion 21 is shifted upwardly, the latch 24 is rocked for freeing the pawl 25 from the rack teeth I5, when the spring 22 will flex upwardly and urge the portion I4 upwardly for freeing the shoe from the step 2.
It is now desired to describe the elongating structure of my improved stilt, which structure may be seen best in Figures 1 and 4 through 7 of the drawings.
Slidably mounted in the stilt body and extending throughout the greater portion of its length is an elongating shank 3D which is formed at its lower end with an enlarged portion 3| carrying a preferably rubber tip or shoe 32 thereon. The shank 3i) may be formed of light weight solid material, or, as shown in Figure '1, may be made of tubular material pressed into the desirsd shape. The shank 39 is substantially circular in shape but has flattened portions 33 and 34 which define a rack 35. The teeth 36 of the rack 35 extend throughout the greater portion of the length of the shank. The stilt body I, at substantially its mid point, is provided with spaced bosses 31 and 38 which are located eccentrically with respect to the axis of the shank 3D and said stilt body. The stilt body is formed with a slot 39 which is defined by inwardly turned lips 4i) and 4I of the bod;7 between the bosses 31 and 3B. The slot 39 receives therethrough the teeth 3S of the rack 35. That is to say, the rack 35 is contained within the stilt body I at all points, except between the bosses 31 and 38, when the flattened portions 33 and 34 of the stilt body define the slot 39 which receives the rack 35 therethrough.
In order to shift the shank 30 longitudinally within the stilt body, I employ a preferably circular actuating nut shown generally at 42. The actuating nut comprises sections 43 and 44 which are semi-cylindrical in contour. The sections are held in proper position by means, of mating pins and sockets 45 and 46. Each of the sections has a threaded portion which, when the sections are placed together in operative position, define a continuous thread 41. As best seen in Figure 5 at 48, there is a slight clearance between the back portion of the stilt body, between the bosses 31 and 38, and the thread 41. This is due tothe fact that the stilt body at this point and the shank are made slightly elliptical in order to permit the rack teeth 36 to be engaged by the thread 41.
Formed in the boss 31 is a vertical entrance key slot 49. There is also formed in the section 43 of the actuating nut 42 a vertical key slot 53. The purpose of the key slots will be described hereinafter.
For shifting the actuating nut 42, I provide an actuating sleeve 5I which slidably fits about the bosses 31 and 38 and the actuating nut sections 43 and 44. The sleeve 5I is formed with a longitudinally disposed key 52 which is adapted to pass through the entrance key slot 49 and rest in the key slot 59. It will be seen that rotation of the sleeve 5I will be communicated to the nut 42 so that said nut will cause shifting of the shank 30 within the stilt body I. In order toretain the sleeve 5I in proper operative position, I
provide a set screw 53 which engages slidably in a groove 54 in the boss 38.
An outer grip 55, of rubber or other suitable material, is fitted about the sleeve 5I.
As it is believed that the manner of operating the elongating structure of my invention will be clearly apparent from the foregoing description, no further description of operation is thought necessary.
The structure shown in Figure '7 of the drawings is identical with that shown in Figures 4, 5 and 6, with the exception of the fact that the stilt body and bosses are pressed from one piece of sheet metal, as are the shank and rack.
Attention is directed to the fact that, inasmuch as the elongating operating mechanism is Vecoentrically mounted with respect to the axis of the stilt body and will be disposed away from the leg of the user, no annoyance to the users legs will be experienced.
Removably connected with th eupper end of the stilt body I, as best seen in Figure 1 of the drawings, is an upper section 56 which is adapted for effecting even greater length to the stilt than that defined by the stilt body and the elongated shank. The section 56 is connected with the stilt body by means of a spring latch 51 which may be of any desired conventional construction.
