Non-binding-mark sock

Abstract

A non-binding-mark sock is provided, including a sock sole and a straight sock leg connected to each other, where the upper portion of the straight sock leg is an opening end. An inner surface of the straight sock leg has at least one transverse annular convex portion near the opening end, where the transverse annular convex portion is sewn by a thread, a plurality of convex segments are formed on an inner surface of the transverse annular convex portion along the thread, and the convex segments protrude from the inner surface of the straight sock leg.

Claims

1. A non-binding-mark sock, comprising: a sock sole; and a straight sock leg connected to the sock sole, an upper portion of the straight sock leg being an opening end, an inner surface of the straight sock leg having at least one transverse annular convex portion near the opening end, the at least one transverse annular convex portion formed by an elastic zigzag thread, the at least one transverse annular convex portion forming a plurality of convex segments and a plurality of U-shaped ends on an inner surface of the at least one transverse annular convex portion along the elastic zigzag thread, and the convex segments protruding from the inner surface of the straight sock leg, wherein the elastic zigzag thread is stitched onto the inner surface of the straight sock leg along an annular orientation by sutures of additional threads to fix the U-shaped ends of the elastic zigzag thread on the inner surface of the straight sock leg and the elastic zigzag thread does not form stitches itself, so as to form the at least one transverse annular convex portion and the convex segments of the at least one transverse annular convex portion, wherein the convex segments of the at least one transverse annular convex portion are transversely located on the inner surface of the straight sock leg, each of the convex segments extends up and down, and the convex segments are arranged in parallel and formed by the elastic zigzag thread only.

DETAILED DESCRIPTION

(5) The aforementioned and further technical contents, features and effects of this present invention will be apparent from the following detailed description of the embodiments with reference to the drawings.

(6) Referring to FIGS. 1 to 4, a non-binding-mark sock according to an embodiment of this present disclosure includes a sock sole 100 and a straight sock leg 200 connected to each other. The upper portion of the straight sock leg 200 is an opening end 210 where a foot enters when wearing socks. During wearing, the sock sole 100 and the straight sock leg 200 are respectively corresponding to the user foot and leg. The length of the straight sock leg 200 is not limited, and may be a short sock at the ankle of the user, or a middle sock below the knee of the user, or a long sock above the knee of the user.

(7) The inner surface of the straight sock leg 200 has three transverse annular convex portions 220 near the open end 210. The annular convex portions are sewn by using threads 221. The threads are elastic threads 221 and stitched onto the inner surface of the straight sock leg 200 along the annular orientation by using a left suture 223 and a right suture 224 in the pattern of overlock stitch, so as to form the annular convex portions 220. In addition, a number of convex segments 222 are naturally formed on the inner surface of the straight sock leg 200 along the stitched elastic threads, where convex segments 222 protrude from the inner surface of the straight sock leg 200.

(8) According to the non-binding-mark sock of the present disclosure, since the inner surface of the straight sock leg 200 has a plurality of annular convex portions 220, and each of the annular convex portions 220 has an extremely large number of convex segments 222 and crosses at a right angle with the straight sock leg 200 in the sock wearing direction. Therefore, when the user wears the sock of the present disclosure, the straight sock leg 200 can generate friction resistance with the user leg due to the plurality of convex segments 222, thereby preventing the straight sock legs from sliding down. Further, the non-binding-mark sock of the present disclosure leaves no binding mark on the user legs due to the friction resistance caused by the plurality of convex segments 222 that stops the sock leg 200 from sliding down, without transverse binding force applied on the user legs caused by binding bands.

(9) Although this present disclosure has been disclosed by way of example, it is not intended to limit this present invention. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of this present disclosure. Therefore, the scope of protection of this present disclosure shall be as defined in the appended claims.
