DETAILED DESCRIPTION OF THE INVENTION
[0023] Referring to FIGS. 3 to 10, a process of making a knee brace 10 in accordance with the invention comprises the steps of putting a tubular cushioning body 1 on a flat mold 5 for shaping (see FIG. 3), activating a sawing device 6 to secure a fabric 2A to either side of the cushioning body 1 aligned with a hollow portion of the mold 5 to form two flexible sheaths 2 (see FIGS. 4 and 5), removing the mold 5 out of the cushioning body 1, putting the cushioning body 1 on a bent, flat mold 1A for shaping, and removing the mold 1A out of the cushioning body 1 (see FIG. 6) or alternatively inserting the mold 1A into the cushioning body 1 and removing the mold 1A out of the cushioning body 1 (see FIG. 7), and inserting a plurality of elastic strips 3 into each of the sheaths 2 to form a knee brace 10 having a hollow 11 (see FIGS. 8, 9A and 9B). The hollow 11 can be enlarged by inserting the hand thereinto (see FIG. 10). Further, the number of the elastic strips 3 can be increased or decreased as desired. A sufficient strength and flexibility of the knee brace 10 is provided by the elastic strips 3. Thus, a person wearing the knee brace 10 on his or her body parts may feel a degree of comfort without worrying it being loosened. Further, the life expectancy of the knee brace 10 is prolonged.
[0024] Referring to FIGS. 11 to 12, the knee brace 10 can be put on the knee C of a person in a first configuration of the invention. The leg may be straightened by pivoting about the knee C as indicated by two solid arrows after bending in exercise. Advantageously, the elastic strips 3 do not exert a force to oppose the strengthening force (or bending force in a bending motion).
[0025] Referring to FIG. 13, the brace 10 can be put on the elbow of the person in a second configuration of the invention. The hand may be straightened by pivoting about the elbow after bending in exercise. Advantageously, the elastic strips 3 do not exert a force to oppose the strengthening force (or bending force in a bending motion).
[0026] Referring to FIGS. 14 and 15, the brace 10 can be put on a joining portion of the hand and the shoulder of the person by putting a looped strap (not labeled) over the shoulder in a third configuration of the invention. The hand may be straightened to align with the shoulder by pivoting about the joining portion after bending in exercise. Advantageously, the elastic strips 3 do not exert a force to oppose the strengthening force (or bending force in a bending motion).
[0027] Referring to FIG. 16, alternatively, the elastic strips 3 are inserted into each of two tubes 4 which are inserted into the sheaths 2 respectively in another embodiment of the invention.
[0028] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
