1956 o. A. HOLDER LEG, KNEE AND FOOT GUARD AND SUPPORT 2 Sheets-Sheet 1 Filed Sept. 28, 1955 INVENTOR David A. Holder ATTORNEY Feb. 7, 1956 A HOLDER LEG, KNEE AND FOOT GUARD AND SUPPORT 2 Shuts-Sheet 2 Filed Sept. 28, 1953 INVENTOR David A. Holder MAJ a1 ATTORNEYJ LEG, KNEE, AND FOOT GUARD AND SUPPORT This invention relates to improvements in pads and United Sta es Patent T -i i b.- 7.195s

magnesium alloy, plastic or other rigid materialand to assistin'maintaining it upon the leg of the wearer, at the upper and lower ends, there are provided harnesses including a strap '15, at one side, having a buckle 16 thereon, and a strap portion17 at the opposite side perforated to receive the buckle prong. 'If desired, as shown in the format invention B, the straps may take the form supports for protecting and supporting without strain I adapted to be worn by those engaged in work which necessitates kneeling, such as in the agricultural industry, incidental to picking of strawberries, cotton and other low growing crops.

Other objects and advantages of the invention will be apparent during the course of the following detailed description. In the accompanying drawings, forming a part of this specification, and wherein similar reference characters designate corresponding parts throughout the several views: I

Fig. 1 is a perspective view showing the application of the improved knee, leg and foot guard and support upon awearer.

Fig. 2 is a fragmentary view, partly in section, showing details of the preferred form of guard and support.

Fig. 3 is a front elevation of the guard and support of Fig. 2. i a Fig.4 is a cross sectional view taken substantially on the line 4-4 of Fig. 3. I

Fig. 5 is a vertical cross sectional view taken through a modified form of knee, leg and foot guard and support.

Fig. 6 is a front elevation of the support of Fig. 5.

Fig. 7 is an enlarged transverse cross sectional view taken throughthe guard and support of Fig. 5, substantially on the line '77 of Fig. 5.

In the drawings, wherein for the purpose of illustration are shown different forms of the invention, the letters A and B may'generally designate the forms of invention shown in Figs. 2 and 5 respectively. Each of the same includes a main casing or'frame supporting padded body portion 10, with associated adjustable foot supporting and rest members 11 and 12 respectively major length thereof. It also'extends around the sides of the leg of the wearer, as is shown in'Fig. l

of the drawings. "The frame or casing'portion ll is t of one piece construction, preferably of aluminium or v or" a strap portion 20 threaded through an opening 21in one of'the sides of the frame 11 and secured for length adjustable purposes in an adapter 22. The opposite side of the frame 11 may have "a loop or staple 24 for detachably receiving a hook '25 secured to the free end of the strap 20. This will enable the straps to be quickly released from the leg. Through disconnection-of the hook 25 from the loop 24 the operator willbe ,able to quickly release the upper part of the guard below the knee from his legs in' order to assist in comfortable standing. I

Referring to the foot rest and support 11 for the form of invention 'A, the same is preferably of rigid material although it may be made'wit'h some springiness to resiliently support the foot in a position without touching a the ground, such as shown in Fig. 1. .The same pref-' A ndin f rwardl extending sk d 37 is formed integral with the portion 35 and has an arcuated skid end 38, as shown in the drawings. The portion 35 of the foot support member 11 is provided with a foot clamping belt assemblage 40 adapted to extend around the ball of the foot of the wearer and around the shoe, in position shown in Fig. 1, to hold the pad at the wearers instep. I

in the form of invention B, the foot guard, and support member 12 is differently constructed. It has a single straight portion 41 instead of the two bars 30 and 31 'of the form of invention'A.

In the form of invention A, the member 11 has the

bar portions

30 and 31 each provided with a pair of elongated slots 50 adapted to receive screw threaded shanks S1 fixedly mounted upon the frame 11, Y and which shanks receive wing nuts or like clamping expedients 52 by means of which the foot guard and support may be properly supported in definite lengthwise adjustment upon the frame 11 in order to properly position the pad 36 upon the instep according to the degree of spacing of the wearerls foot from theknee. l

In the form of invention B, showing the foot guard and support 12, the portion 41 is provided with a single pair of longitudinally extending slots 55 adapted to receive screw threaded shanks 56 fixed upon the frame 11 wing nuts or like clamping members 58 cooperating to provide the desired lengthwise adjustment of the foot guard and support portion 12 upon the frame or casing portion. The support '12 has a skid bar 37 and a curved skid end 38. It also has an instep pad 35 and foot attaching strap 40*.

'It will be noted that the frame or casing portions are of one piece construction; the foot rest and support portions 11 and 12, being'forwardly and downwardly angled with respect to the line of the casings 10, and thus directlysupporting the foot and lower leg of the wearer. The'foot is supported in spaced relation from the ground is supported in a natural position upon the device free W of strain] The skid endlis; spaced upwardly from the noted from Fig. 1, and yet the device supports theknee,

leg and also foot in comfortable positions without strain. Various changes inthe shape, size and arrangement of parts may be made to the form of invention herein shown and described without departing from the spirit of the invention or scope of the claims.

I claim:

.1. In a device for supporting the leg and foot of a wearer while in kneeling position the combination of a of the shin bone of the wearer above the ankle, and a foot supporting ground engagingmember connected to the lower portion of said frame and extendingtherebelow at an angle thereto and having means thereon for directly receiving and supporting the upper front portion of the foot of the wearer thereon, said ground en- 3. In a devicefor supporting the leg and foot of a wearer while in kneeling position the combination of an elongated rigid frame having socket means for attachment to and reception of the lower leg of the wearer along the shin bone of the wearer above the ankle, and

a relatively stifI foot supporting and receiving and ground engaging skid extension connected to the lower end of said frame and projecting therebelow at an angle thereto and extending forwardly of the line of the frame, said skid member being provided with means for directly receiving the upper part of the foot of the wearer thereupon and being sufliciently resilient to comfortablyl support the foot and lower leg of thewearerabove a ground surface.

4. In a knee, leg and foot guard and supporting device for application upon the foot of a wearer the combination of a rigid elongated frame having means for attachment to the lower leg of the wearer for extension along 'rigid elongated frame having means for attachment to the lower legof the wearer for extension along the front gaging member at its extreme end remote from the frame 30 constituting a ground engaging skid.

2. A device as set forth in claim 1 whereon the skid is provided with a ground engaging curved surface to facilitate sliding along a ground surface.

the front of the shin bone of the wearer above thev ankle, a foot receiving and supporting ground engaging member mounted at an angle to said frame and connected thereto for lengthwise adjustment upon the frame for extension therebelow and forwardly whereby to receive the foot of the wearer below the ankle joint and support the foot of the wearer in an elevate'd position above the ground when the wearer is in a kneeling position.
