Abstract
The present invention relates to a non-slip footwear having a cushion separation part, in which a non-slip material is formed on an inner surface and an outer surface of a bottom of a footwear such as a sock, wherein the non-slip material of the inside and the outside are arranged alternately and a cushion separation part is formed therebetween such that maintenance of a non-slip function and prevention of skin injury are smoothly performed.
Claims
exact text as granted — not AI-modified1 . A non-slip footwear having a cushion separation part, in which an inner surface part ( 1 a ) contacting a foot of a wearer is formed on a top surface of a bottom of a foot wear main body ( 1 ) for accommodating the foot of the wearer and an outer surface part 1 b is formed on a bottom surface of the bottom, the non-slip footwear comprising:
an outer circumferential non-slip part ( 10 ) made of a material preventing slippage and formed on a circumference of the outer surface part ( 1 b ); a plurality of outer horizontal non-slip parts ( 20 ) formed in left and right directions of a sole and a plurality of outer vertical non-slip parts ( 30 ) formed in front and rear directions of the sole, which are made of the material preventing slippage in an inner space surrounded by the outer circumferential non-slip part ( 10 ); an outer slip part ( 40 ) surrounded by the outer horizontal non-slip parts ( 20 ) and the outer vertical non-slip parts ( 30 ); and an inner non-slip part ( 60 ) made of the material preventing slippage and disposed in the outer slip part ( 40 ) on a plane while forming a cushion separation part ( 50 ) that is a space spaced apart from the outer horizontal non-slip parts ( 20 ) and the outer vertical non-slip parts ( 30 ), which are adjacent to each other on the plane, wherein the inner non-slip part ( 60 ) comprises a first inner non-slip part ( 61 ) formed in correspondence to any one position of a toe, a fore foot, a rear foot, and a foot blade of a user and a second inner non-slip part ( 62 ) formed on a portion except fro the first inner non-slip part ( 61 ), and the cushion separation part ( 50 ) of the first inner non-slip part ( 61 ) is less in size than the cushion separation part ( 50 ) of the second inner non-slip part ( 62 ).
2 . The non-slip footwear of claim 1 , wherein the cushion separation part ( 50 ) of the first inner non-slip part ( 61 ) has a size of 2 mm to 4 mm, and the cushion separation part ( 50 ) of the second inner non-slip part ( 62 ) has a size of 5 mm to W mm.
3 . The non-slip footwear of claim 1 , wherein each of the outer circumferential non-slip part ( 10 ), the outer horizontal non-slip part ( 20 ), and the outer vertical non-slip part ( 30 ) is bonded to the footwear main body ( 1 ) through a hot-melt adhesive layer ( 73 ), and
each of the inner non-slip part ( 60 ), the outer circumferential non-slip part ( 10 ), the outer horizontal non-slip part ( 20 ), and the outer vertical non-slip part ( 30 ) is made of a wet-type polyurethane sheet in which a column cell having a reverse tumbling doll shape having a wide top and a narrow bottom is formed therein, and a non-slip groove ( 72 ) entirely or partially communicating with a column cell ( 71 ) is formed on an opposite surface of a portion contacting the hot-melt adhesive layer ( 73 ).
4 . The non-slip footwear of claim 3 , wherein the footwear main body ( 1 ) is made of water permeable cloth in which moisture passes between the inner surface part ( 1 a ) and the outer surface part ( 1 b ).
5 . The non-slip footwear of claim 4 , wherein a punching hole ( 80 ) is formed in the footwear main body ( 1 ) through needle punching treatment from a surface of the cushion separation part ( 50 ) to the outer surface part ( 1 b ), and
as the punching treatment is performed in a state in which liquefied resin is applied on a surface of the needle, the liquefied resin applied on the needle is stained on a wall surface of the punching hole ( 80 ) and then cured to form a resin wall part ( 81 ).Join the waitlist — get patent alerts
