Inner-outer non-skid sleeve worn on hand or foot

Abstract

An inner-outer non-skid sleeve worn on a hand or foot, including a front sleeve portion and a rear sleeve portion coupled together. Inner surfaces of the front sleeve portion and the rear sleeve portion have an inner non-skid layer so as to be partially covered with the inner non-skid layer but partially exposed. The inner non-skid layer has a predetermined thickness and thus protrudes from the inner surfaces of the sleeve body. Outer surfaces of the front sleeve portion and the rear sleeve portion have an outer non-skid layer so as to be partially covered with the outer non-skid layer but partially exposed. The outer non-skid layer is in contact with an external object or the ground. The outer non-skid layer has a predetermined thickness and thus protrudes from the outer surface of the sleeve body.

What is claimed is: 
     
         1 . An inner-outer non-skid sleeve worn on a hand or foot, comprising:
 a front sleeve portion and a rear sleeve portion coupled together, the front sleeve portion being fitted to fingers of a human hand or toes of a human foot, and the rear sleeve portion being fitted to a palm of the human hand or a sole of the human foot,   wherein the front sleeve portion and the rear sleeve portion are made of a flexible, hygroscopic material and joined to form a sleeve body and an opening, allowing the human hand or the human foot to be inserted into the sleeve body through the opening,   wherein surfaces of the front sleeve portion and the rear sleeve portion are defined as inner surfaces when located inside the sleeve body, and the inner surfaces of the front sleeve portion and the rear sleeve portion have an inner non-skid layer so as to be partially covered with the inner non-skid layer but partially exposed, wherein the human hand or the human foot comes into contact with the inner non-skid layer and the inner surfaces of the front sleeve portion and the rear sleeve portion when the inner-outer non-skid sleeve is worn on the human hand or the human foot to allow the human hand or the human foot to be positioned in the sleeve body, wherein the inner non-skid layer has a predetermined thickness and thus protrudes from the inner surfaces of the sleeve body,   wherein surfaces of the front sleeve portion and the rear sleeve portion are defined as outer surfaces when located outside the sleeve body, and the outer surfaces of the front sleeve portion and the rear sleeve portion have an outer non-skid layer so as to be partially covered with the outer non-skid layer but partially exposed, wherein the outer non-skid layer is in contact with a ground when the sleeve body is worn on the human hand or the human foot with the palm pressing against the ground or the human foot treading on the ground, wherein the outer non-skid layer has a predetermined thickness and thus protrudes from the outer surfaces of the sleeve body.   
     
     
         2 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein the inner non-skid layer and the inner surface of the front sleeve portion are necessarily disposed at the front sleeve portion and correspond in position to fingerprints and ventral sides of the fingers of the human hand or toe prints of the toes of the human foot. 
     
     
         3 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein the outer non-skid layer and the outer surface of the front sleeve portion are necessarily disposed at the front sleeve portion and correspond in position to fingerprints and ventral sides of the fingers of the human hand or toe prints of the toes of the human foot. 
     
     
         4 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein when the sleeve body is worn on the human hand or the human foot with the palm pressing against the ground or the human foot treading on the ground, the inner non-skid layer and the inner surface of the rear sleeve portion as well as the outer non-skid layer and the outer surface of the rear sleeve portion are disposed at a ground-pressing force acting point of the sleeve body. 
     
     
         5 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein the inner non-skid layer and the outer non-skid layer are disposed at the sleeve body formed by joining the front sleeve portion and the rear sleeve portion and correspond in position to the back of the human hand or the dorsal side of the human foot. 
     
     
         6 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein the sleeve body further comprises a radical sleeve portion coupled to the front sleeve portion and the rear sleeve portion, with the opening formed at the radical sleeve portion and being in communication with the inside of the sleeve body, and the radical sleeve portion is fitted around a wrist of the human hand or an ankle of the human foot. 
     
     
         7 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 6 , wherein the inner non-skid layer is disposed on an inner surface of the radical sleeve portion, and the outer non-skid layer is disposed on an outer surface of the radical sleeve portion. 
     
     
         8 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , wherein the inner non-skid layer and the outer non-skid layer are disposed at the sleeve body and correspond in position to a lateral side of the human hand or the human foot when the sleeve body is worn on the human hand or the human foot. 
     
     
         9 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 8 , wherein the inner non-skid layer and the outer non-skid layer are disposed at the sleeve body and correspond in position to a knifehand of the human hand or a knifefoot of the human foot when the sleeve body is worn on the human hand or the human foot. 
     
     
         10 . The inner-outer non-skid sleeve worn on a hand or foot according to  claim 1 , further comprising a plurality of penetrating holes penetrating the sleeve body, the inner non-skid layer and the outer non-skid layer.
