Description

Binding band structure of snowshoe

Technical Field

The invention relates to an outdoor sports article, in particular to a binding belt structure of a snowshoe.

Background

Snow shoes (Snowshoes), also known as snow paws, bear-palm shoes, snow-treading boards, snow covers, are footwear for walking on snow. The snowboarding shoe can prevent the foot from completely sinking into the snow by distributing the weight of the human body over a larger area. The traditional snowboarding shoes are mostly composed of four parts, namely shoe frames, vamps, shoe teeth and uppers, the uppers comprise heel belts and binding belts, and the traditional snowboarding shoes are used by people by adopting the modes of tying and untying the shoe belts, but the mode is very inconvenient, if the shoe belts are tightly tied, the shoes are tied into dead knots, the shoes are very inconvenient to take off, and the shoes are heavy to walk on snowfields and easy to fall down.

The present snowboarding shoe capable of quickly tying and taking off the shoe string also appears, for example, the Chinese patent 'a snowboarding shoe' with patent number 200920115845.X includes outer frame, bottom lining face, foot seat, rear base, front base, supporting belts, shoe string, two shoe pads and two fastening belts, a hole for moving shoe pad and front base is opened at the front position of the middle of bottom lining face, the bottom lining face is fixed on the outer frame, the supporting belts are fixed at the front position of the middle of the outer frame, the middle of the supporting belts is spanned on the hole of the bottom lining face, the two shoe strings are mounted on the lugs of the shoe pad, and the two fastening belts are respectively fixed at the left side and the right side of the shoe pad. The snowshoe adopts two shoelaces which are arranged in parallel and are fastened and fixed through the buckles respectively, although the structure is simpler, the snowshoe is not convenient and fast enough, and the shoelaces are easy to loosen.

And Chinese patent No. 201120333042.9 "A bandage structure for snowshoe" is characterized by comprising: the left side and the right side of the treading part are respectively and symmetrically provided with a front perforating piece and a rear perforating piece; the middle part of the buckle body is provided with a rectangular hole, and two longitudinal columns are arranged in the rectangular hole to divide the rectangular hole into three longitudinal strip-shaped holes; and two ends of the binding band respectively penetrate through the two perforating pieces at the front end of the treading part from the lower part, then respectively return upwards and return upwards after being respectively crossed and then respectively penetrate through the two perforating pieces at the rear end from the lower part, then respectively return upwards after passing through the middle strip-shaped holes in the buckle body from two sides of the bottom of the buckle body, respectively bypass from the upper parts of the longitudinal columns at two sides, and finally penetrate downwards through the strip-shaped holes at two sides. This bandage structure is simpler, the simple operation, only needs a bandage and detains the body cooperation and just can tighten up the shoes, but its structure is reasonable inadequately, and the bandage perforation is more troublesome, and the knot body sets up at the middle part moreover, can cause the instep to be uncomfortable, and the front end of shoes does not have the spacing point yet moreover, if the shoelace is not hard up can cause the foot to move forward, consequently structurally still needs further improvement.

In addition, the cross section of the shoe frame of the traditional snowshoe is made of round pipes, so that the snowshoe is light in weight and convenient to carry and use, but the cross section of the traditional snowshoe is round, so that the snowshoe is not ideal in capability of breaking ice and snow, the difficulty of fixedly mounting the side teeth and the vamp on the shoe rack is high, the firmness is not good enough, and further improvement is needed on the structure.
