Description

Jan. 22, 1963 N. scHuLMAN KNEE CAP BRACE 2 Sheets-Sheet l Filed Nov. 14. 1961 INVENTOR. NORMAN SCH ULMAN BY 2 Sheets-Sheet 2 INVENTOR. .NORMAN SCHULMAN N. SCHULMAN KNEE CAP BRACE Jan. 22, 1963 Filed Nov. 14, 1961 United States Patent O 3,074,4@ KNEE CAP BRACE Norman Schulman, 55 Grist Mill Lane, Great Neck, NX. Filed Nov. 14, 1961, Ser. No. 152,279 2 Claims. (Cl. 12S-165) This invention relates to a knee brace, stabilizer or support.

An object of the invention is to provide an elastic sleeve adapted to engage about a knee joint, with stays fixed on the sleeve to localize support, the sleeve having a knee-cap receiving and engaging portion to stabilize the sleeve on the knee.

Other objects are to provide a knee supporter which can be readily applied and removed; which will not interfere with normal movements of the limbs; which will support an unstable knee resulting from cartilage or muscle injuries; which yields elastically transversely and longitudinally; which is easily washed; and which can be manufactured at low cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a front oblique view of a knee supporter embodying the invention.

FIG. 2 is a horizontal or transverse sectional view taken on staggered line 2 2 of FIG. l.

FIG. 3 is a longitudinal section on a rdeuced scale taken on line 3 3 of FIG. 2.

FIG. 4 is a perspective view of a stay and pocket for the stay prior to assembly for mounting on the knee supporter.

FIG. 5 is a front oblique view of another knee supporter according to the invention.

FIG. 6 is a longitudinal sectional view taken on line 6 6 of FIG. 5.

FIG. 7 is a cross-sectional view taken on line 7 7 of FIG. 5.

FIG. 8 is a longitudinal sectional view taken on line 8 8 of FIG. 7.

Referring to FIGS. 1-3, there is shown knee supporter 10 including a cylindrical sleeve 12 formed of two-way stretch elastic material preferably made of nylon. The sleeve may be knitted on a full-fashioned hosiery knitting machine without longitudinal seams. Upper and lower ends of the sleeve may be folded over to form doubled elastic annular hems 14, 16 which may be secured by chain stitching 18, 18. Alternatively, the sleeve may be knitted to provide selvages at opposite ends. A hole 19 is formed in the side of the front half of the sleeve located centrally between opposite ends of the sleeve. The elastic rim 2l) of the hole may be strengthened by an elastic binding 23 folded over the rim and secured to stitching 24. This apertured, reinforced structure is adapted to receive kneecap C of knee K indicated in dotted lines in FIG. 2, to secure the sleeve on the knee joint and prevent it from riding up or down the calf or thigh of the wearer.

Circumferentially spaced from' the hole 19 are two pairs of longitudinally aligned flexible stays 26, 27 and 28, 29. The stays are enclosed in rectangular fabric pockets 30, 31 and 32, 33. The pockets may have turnedin edges 35 secured by chain stitching 37 to the front side of the sleeve. The stays are elongated rectangular structures which may be made of plastic or metal material; see FIG. 4.

The t-wo stays in each pair are spaced in the axial di- ICC rection of the sleeve by a short elastic section 36 of the sleeve fabric. This short section serves as a hinge between the stays and permits free flexing of the sleeve while the wearer bends his knee, without binding. At the same time the stays which are rather stiilly flexible effectively support the local parts of the thigh and calf.

It will be noted that outer lateral edges E of the pockets and stays are spaced circumferentially somewhat less than apart on the front half of sleeve 12 so that pressure is exerted by the stays on the front of the wearers thigh and calf. Thus, little or no pressure is applied by the stays to muscles which must have free movement while maximum support is given to cartilaginous parts of the knee joint.

In FIGS. 5-8 is shown another knee supporter 10a generally similar to supporter 10. The supporter 19' has a cylindrical knitted fabric sleeve body 12a which is elastic both longitudinally or axially and transversely or circumferentially like sleeve 12. Upper and lower edges of the sleeve body 12a are turned in to form hems 14a and 16' which are secured by stitching l, 18h. Integrally knitted with the front side of the sleeve midway between the ends thereof is a shallow elastic pocket or sac 21 adapted to receive the kneecap of the wearers knee joint. The pocket 21 engages around and covers the kneecap in contrast to the apertured structure of sleeve 12 in which the kneecap C will be exposed. The elastic walls of the pockets 2l engage the kneecap and effectively prevent the sleeve from riding up or down the thigh or calf, respectively, of the wearer.

Four stays 2629 are arranged in two circumferentially spaced pairs. The stays are enclosed in elongated fabric pockets Sty-33. The pockets are secured by stitching 37 to the front half of the cylindrical sleeve 12a.

It is preferred that the sleeves 12 and 12a be knitted of elastic nylon yarn in a two-way stretch weave. This will enable the knee supporter to yield in whole and in part in axial and circumferential directions to permit freedom of movement of the knee joint while affording maximum support.

The cylindrical sleeve can be readily put on and taken off the leg of the wearer. It is washable for reuse without losing its shape or elasticity.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modications may be made within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent 1s:

1. A knee joint supporter, comprising a cylindrical sleeve, means centrally located between opposite open ends of the sleeve adapted for engaging around the kneecap of the knee joint, two pairs of spaced fabric pockets secured to said sleeve, and two pairs of flexible stays respectively enclosed insaid fabric pockets, said pockets being circumferentially spaced apart with said means being disposed therebetween, the stays in each pair of pockets being disposed in longitudinal alignment parallel to the axis of the sleeve and longitudinally spaced apart by an elastic hinge forming part of the sleeve, said means being an elastic fabric pocket integrally knitted with said sleeve, said opposite open ends of the sleeve being formed with turned-in hems providing a double, reinforced elastic structure at each end of the sleeve.

2. A knee joint supporter, comprisin3 a cylindrical sleeve, means centrally located between opposite open ends of the sleeve adapted for engaging around the kneecap of the knee joint, two pairs of spaced fabric pockets secured to said sleeve, and two pairs of llexible stays respectively enclosed in said fabric pockets, said pockets being circumferentially spaced part with said means being disposed therebetween, the stays in each pair of pockets being disposed in longitudinal alignment parallel to the axis of the sleeve and longitudinally spaced apart by an elastic hinge forming part of the sleeve, said means being a hole in the sleeve, said hole having an elastic rim', and an elastic binding 0n said rim, said opposite open ends of the sleeve being formed with turned-in stitched 2,195,024 Bullock Mar. 26, 1940 FOREIGN PATENTS 663,643 Germany Aug. 10, 1938 133,166 Switzerland Aug. 1, 1929
