DETAILED DESCRIPTION OF THE INVENTION

Exemplary, non-limiting embodiments of the invention will be disclosed. However, it is to be understood that limiting the description to the preferred embodiments of the invention is merely to facilitate discussion of the present invention and it is envisioned that those skilled in the art may devise various modifications without departing from the scope of the appended claim.

The present invention provides a slip-on compression sock (100 or 200) as shown in Figure 1 to 12. The sock is mainly made up of a combination of weaving methods at different sections. Different weaving methods offer a different level of elasticity (hence, compression effect) and breathability. Meanwhile, the sock is derived from fabric incorporated with FIR emitting particles. In view of this, the weaving combination and fabric used herein works in association with each other to offer comfort and support to the leg of a wearer while reducing the symptoms due to venous insufficiency, lack of fluid circulation, or the like.

A first embodiment of the present invention provides male version of compression socks male 100 whereas a second embodiment of the present invention provides a female version of compression socks 200.

Figure 1 and 2 shows the first embodiment of the present invention. According to Figure 1 and 2, the sock 100 comprises a foot section 101 and a lower leg section 102. The sock 100 are designed such that it exerts substantial compression effect on a wearer. More particularly, the sock 100 comprises at least two distinct zones configured with elasticated feature. One of the distinct zone (denoted by‘D’ in Figure 1) is at the lower leg section 102 which is elasticated so as to provide a first compressive effect. Another distinct zone (denoted by‘B’ in Figure 1) is at the foot section 101 which is elasticated between toe and heel portions of the foot section so as to provide a second compressive effect, especially at the foot arch, when worn.

Accordingly, the first and the second compression effects can be different from one another. Preferably, the second compression effect are often higher than the first compression effect so as to provide additional support for foot arch. For instance, the first compression effect ranges from 15 to 24 hpa whereas the second compression effect ranges from 16 to 28 hpa.

As aforementioned, the elasticity of the sock is derived from weaving combination and fabric used. In the present invention, each section of the sock may comprised of one or a combination of knittings which intertwine into weaving patterns. In some circumstances, more than one type of knittings can be overlapped or made complementary to each other. If necessary, an extra thread can be inserted thereinto (known as‘insert thread’ hereinafter) so as to achieve the weaving pattern. In the present invention, a front thread and a back thread can be intertwined close to each other in a plain knitting. Alternatively, a front thread and a back thread can be knitted spaced apart in an arranged manner to achieve a certain pattern. Preferably, an insert thread can be used in between the front and back threads so as to create ribbed or spiral features.

In the first embodiment, also referring to Figure 1, the lower leg section 102 is derived from weaving patterns denoted by 103, 104, 105, 106 and 107. Weaving patterns denoted by 103 and 104 are derived from a combination of plain knitting and a‘3 by G transverse knitting (as shown in Figure 3) hence providing a ribbed feature. More particularly, weaving pattern denoted by 103 has a double welt feature at edges. Weaving pattern denoted by 105 is derived from a combination of plain knitting and‘1 by 1 transverse’‘2 by 2 vertical’ spiral knitted mesh (as shown in Figure 4). Therefore, weaving pattern denoted by 105 offers breathability when worn. The combination of weaving patterns denoted by 104 and 105 across the sock offers extra elasticity so as to obtain the first compression effect when worn. Weaving pattern denoted by 106 is derived from plain knitting (as shown in Figure 5). It shall be understood that weaving pattern denoted by 106 extends partially to the foot section 101. Further, weaving pattern denoted by 107 is derived from tuck knitting (as shown in Figure 6) to obtain an anti-slip feature on the sock. It shall be understood that weaving pattern denoted by 107 extends to the foot section 101 so as to substantially surrounds the ankle of a wearer when worn.

Further, the foot section 101 is derived from weaving patterns denoted by 106, 107, 108, 109, and 110. As aforementioned, weaving pattern denoted by 106 is derived from plain knitting (as shown in Figure 5) extended from the lower leg portion 102. Weaving pattern denoted by 108 is derived from mesh knitting which comprises a combination of‘ 1 by 1 transverse’ ‘2 by 2 vertical’ spiral knitted mesh on plain knitted mesh (see Figure 7). Therefore, weaving pattern denoted by 108 also offers breathability when worn. Further, weaving pattern denoted by 109 is derived from a combination of plain knitting and a‘3 by transverse knitting (as shown in Figure 3) hence providing a ribbed feature. A combination of weaving patterns denoted by 108 and 109 across the sock offers extra elasticity so as to obtain the second compression effect, especially at foot arch, when worn. Further, weaving pattern denoted by 110 derived from plain knitting and l x l seed knitting (see Figure 8) provides a ribbed feature which offers breathability and flexibility at upper foot area when worn. Further, weaving pattern denoted by 107 is also derived from tuck knitting (as shown in Figure 6) to obtain an anti-slip feature at toes part of the sock. Figure 9 shows the second embodiment of the present invention. According to Figure 9, the sock 200 comprises a foot section 201 and a lower leg section 202. The sock 200 are designed such that it exerts substantial compression effect on a wearer. More particularly, the sock 200 comprises at least two distinct zones configured with elasticated feature. One of the distinct zone is at the lower leg section 202 which is elasticated so as to provide a first compressive effect. Another distinct zone is at the foot section 201 which is elasticated between toe and heel portions of the foot section so as to provide a second compressive effect, especially at the foot arch, when worn.

In the second embodiment, also referring to Figure 9, the lower leg section 202 is derived from weaving patterns denoted by 203 , 204 and partially 205. It shall be noted that weaving pattern denoted by 205 extends to the foot section 201. Weaving patterns denoted by 203 and 204 are derived from a combination of plain knitting and a‘3 by transverse knitting (combined and shown in Figure 10) hence providing a ribbed feature (refer Figure 9). More particularly, weaving pattern denoted by 203 has a double welt feature at edges. The weaving patterns denoted by 204 across the lower leg section 202 offers extra elasticity so as to obtain the first compression effect when worn. Further, weaving pattern denoted by 205 is derived from a combination of plain knitting and‘ 1 by 1 transverse’‘2 by 2 vertical’ spiral knitted mesh (as shown in Figure 12). Therefore, weaving pattern denoted by 205 offers breathability when worn. Further, the foot section 201 is derived from weaving patterns denoted by 204, 205 and 206. It shall be noted that the weaving pattern denoted by 205 extends from the lower leg section 202 and offers breathability when worn. The weaving patterns denoted by 204 across the foot section 201 offers extra elasticity so as to obtain the second compression effect when worn. On the other hand, weaving pattern denoted by 206 is preferably derived from plain stitches (as shown in Figure 11).

In both embodiments, the first and the second compression effects can be different from one another. Preferably, the second compression effect are often higher than the first compression effect so as to provide additional support for foot arch. For instance, the first compression effect ranges from 15 to 24 hpa whereas the second compression effect ranges from 16 to 28 hpa. Furthermore, the compression effects for male and female wearer may be different. Preferably, the compression effects of a sock for female has relatively higher compression effects than those for the male.

The fabric used to produce the sock 100, 200 are mainly derived from yarns spun with fibers selected from polyester, cotton, rayon, polyurethane, nylon, or a combination of any two of more thereof. Further in particular, the yarns are spun with fibers derived from 38% to 42 % of polyester, 38% to 42 % of cotton, 8% to 11 % of rayon, 3% to 6% of polyurethane, and 1% to 2 % of nylon. The far-infrared (FIR) emitting particles are compounded into fibres, preferably rayon or nylon, before being spun into yarns. Hence, the FIR emitting particles are substantially spreaded throughout the sock. The present invention may be embodied in other specific forms without departing from its essential characteristics. The described embodiments are to be considered in all aspects only as illustrative and not restrictive. The scope of the invention is, therefore indicated by the appended claims rather than by the foregoing description. All changes, which come within the meaning and range of equivalency of the claims, are to be embraced within their scope.
