ORTHOPEDIC BRACES Filed June 26, 1961 2 Sheets-Sheet 2 INVENTOR. HARLEY R. FROH MADER ATTOR NEYS United States Patent O 3,086,522 ORTHOPEDIC BRACES Harley R. Frohmader, 14411 W. Cleveland, New Berlin, Wis. Filed .lune 26, 1961, Ser. No. 119,622 7 Claims. (Cl. 12S-80) My invention relates to orthopedic braces and more particularly to a foot and leg brace to correct improper deformities of the limb.

It is more or less common practice to use orthopedic braces -to correct deformed limbs of infants. These limbs may be unnaturally twisted or distorted with relation to the normal and desired form of limb. In order to correct these deformities, brace structures are applied to the deformed limb in order to force its growth toward the normal position or disposition. A major purpose of the present invention is the provision of an improved brace structure for application to a deformed leg or foot, and with the structure being so formed that it enables corrective forces to be applied to the leg and foot in many varied directions.

Another object of my invention is to provide such a device that is -constructed in a manner that will permit it to be adjusted and retained at any predetermined position after adjustment.

Still another object of my invention is to pr-ovide a device of the character described that retains the leg and thigh portion in many angular relations, while preventing any relative displacement.

Another object of my device is to provide a structure that permits convenient application of cushions and padding to conform to the contour of the muscles and bone structure of the limb being serviced.

A still further object is to provide a device that permits variant angular disposition of the l:foot in relation to the leg.

The device described, illustrated and claimed herein is applicable to either the right or left leg and adjustable to take care of variations in size as the childs foot and leg develops. It is simple in constructionl and is easy to apply or remove.

`Other and further objects of my invention Will become more apparent as the description proceeds, when taken in conjunction with the drawings, in which:

FIGURE l is a perspective view of the entire assembled device applied to the limb, shown in phantom;

IFIGURE 2 is a vertical cross sectional view of the device shown in FIGURE l;

FIGURE 3 is a top or plan View of the base showing the angularly adjustable support plates; 4

FIGURE 4 is a similar view as shown in FIGURE 3 with the plates equipped with pliable foot supports;

FIGURE 5 is a side view of the device applied to the limb shown in phantom and illustrating the foot portion angularly disposed and retained in that position with the toe portion of the foot higher than the heel;

FIGURE 6 is a rear view of the device illustrating the manner in which the toot may be angularly disposed in either direction sideways relative -to the leg;

FIGURE 8 is a front View of the structure shown in FIGURE 7.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, thecharacter 10 designates a base portion, which forms a foot support. Base y10 may be constructed of any lightweight rigid material, such as wood, plastic or the like. Obviously thisbase portion 10 may be of 3,086,522 Patented Apr. 23, 1963 any shape or contour to conform to the shape of the foot of the wearer and may be equipped with a metal top plate shown as v11 covering the upper face of thebase 10 and attached thereto by means of the screws shown as i12, or in any other convenient manner.

Thebase 10 is shown provided withelongated recesses 13 and 13' and the plate 11 is equipped with a pair of spaced, elongated slots shown as 14 and 15 extending longitudinally ofbase 10. These slots accommodate bolts i16 and I17, respectively, extending upwardly therethrough yfrom therecesses 13 and 13. The bolts havenuts 28 mounted thereon, engaging T-shaped grooves 18 and 19, respectively, recessed in the undersurfaces of theblocks 20 and 21, respectively.lBlocks 20 and 21 are adapted to be turned with relation to the upper surface of the plate 11. In the normal position, thegrooves 18 and 19 extend at right angles to theelongated slots 14 and 15, as appears in FIGURES 1 and 3. This arrangement permits the pivoted movement of the blocks V20 and 21 to any predetermined position or angle, as shown in the dotted lines in FIGURE 3.

A swivel ball joint mounting is attached to the top plate 11 at'the rear thereof by means ofrivets 23, as shown in AFIGURE 2. lMounting 22 supports a leg support in the form of arod 24 extending upwardly therefrom. Rod `24 is adapted to be held in a selected tixed position by means of theset screws 25, which engage the ball on the end of r-od 24. Atubular sleeve 26 slidably engages the upper end ofrod 24 and is held in any predetermined position by theset screw 27, which engagesrod 24.

The upper end of thesleeve 26 has a softpliable band 28 attached thereto. This band may be constructed of leather, cloth, plastic or the like and is shown equipped witheyelets 29 Ifor accommodating a lace y(not shown). lObviously any -type of fastening such as a buckle or the like may be employed.Band 28, which is adapted to be tted around the upper leg or thigh, permits attachment of the device to a point above the knee of the wearers leg, which is shown as 30 by the dotted lines.

Sleeve 26 also has abracket 31 slidably mounted thereon for supporting aband 32 adjustably mounted on the bracket 3'1 by means of the bolt andslot connection 33. Aset screw 34 holdsbracket 31 in a lixed position on thesleeve 26, while permitting angular and height adjustment ofband 32 with respect to the axis ofrod 24.

In FIGURES 7 and 8 theband 28 is hingedly attached to the top of thesleeve 26 by means of themember 44 attached to theband 28 andthemember 45 attached to thesleeve 26 and hingedly engaged by thescrew 43 so theband 28 may be pivoted about the axis ofscrew 43 and then retained in any selected position to one side or the other of the axis of theleg supporting rod 24.

I-f desired, another bracket shown at 35 may slidably engage therod 24 belowbracket 31. This bracket is lixed in position by theset screw 36. This bracket is similar tobracket 31. Aband 37 is adjustably mounted at 38 on the bracket '35 -for adjustment radially ofrod 24.

Thebands 32 and 37 are constructed similar to the ban-d '28, are made from soft pliable material and are held by means of buckles or laces. These bands readily permit the support and engagement of padding or the like.

Thefront block 20 is shown with an upwardly extended softpliable band 39, which band may also be provided with lacking or buckles to support the forward or toe portion of the foot.Block 21 is shown with acounter portion 41 of a shoe ty-pe construction mounted thereon to support the heel portion of the foot. Thecounter portion 41 is also shown with lacing similar to the toe portion orband 39. This arrangement permits the support of the ankle together with the heel portion of the foot. Thetoe band 39 and thecounter portion 41 may be connected together by means of t-he strap and slot arrangement.

The twoblocks 20 and 21 are spaced from one another. They may be variantly spaced longitudinally of support and may have variant lateral and angular positions relative to one another and to the support `10. They are retained in a fixed position by means of thebolts 16 and 17 to support the foot in any predetermined position or angle -for the correction of the deformities.

From the above description it will be seen that the device will retain the foot at any selected disposition relative to the thigh and lower leg by means of thestraps 28, 32 and 37, thestrap 28 being applied to the thigh and thestraps 32 and 37 to the leg of the wearer.

The brace shown and described herein is easily used Yfor many corrective situations. For example, it may be used to correct the disposition of the plane of the lfoot relative to the lower leg by twisting thefoot support 10 upwardly or downwardly with relation to theleg support 24 and then xing it in position as is shown in FIGURE 5. The device may be used to twist the general plane of the foot relative to the lower leg, by twisting the general plane of thesupport 10 relative to the lower leg and theleg support 24 as appears in FIGURE 6. The lower leg may be positioned at selected angular dispositions relative to the upper leg through proper adjustment of theband 28 relative to theleg support 24 as appears in FIGURES 7 and 8. The foot of t-he wearer may have lateral forces applied thereto by proper positioning of theblocks 20 and 21 on thesupport 10 so that the `foot and ankle structure are forced toward the normal position. Since each of theblocks 20 and 21 individually and independently fixed in position, the forward portion of the foot may be adjusted relative to the heel portion by setting theblocks 20 and 21 at desired lateral positions on thesupport 10 and with the blocks twisted about axes prependicular to the plane of t-he support 10 with relation to one another as appears in FIGURE 4.

The struct-ure is easily formed and lixed in the selected and desired position of rigidity so as to apply the desired corrective forces to the limb of the wearer.
