Description

Technical Field

[0001] The utility model relates to a snowshoe fixer, in particular to a snowshoe fixer. Background Art

[0002] Snowshoes work by spreading the weight of the human body over a larger area, which prevents the foot from sinking completely into the snow. Traditional snowshoes are made of hardwood frames woven with raw leather straps. Some modern snowshoes are similar, except that most are made of light metal, while others are made of a single piece of plastic and straps, thus realizing a modern production model with good quality and high durability. Modern snowshoes usually use a fixing device to detachably fix the active shoes and snowshoes on the user's feet. The fixing devices on the market usually use multiple straps to fix the snowshoes and active shoes, which are difficult to operate and have a complex structure.

[0003] Upon investigation, Patent No. CN201520530631.4 discloses a double-drawn snowshoe binding, including a front cover and a base, the front end of the front cover is fixedly connected to the base to form a toe part, and the rear end of the front cover extends backward to the upper middle part of the base to form a back part of the shoe, which also includes a loose webbing, a first tensioning buckle and a second tensioning buckle, a first winding buckle, a second winding buckle and a tightening webbing; by setting adjustment components such as the loose webbing, the first tensioning buckle and the second tensioning buckle, the first winding buckle, the second winding buckle and the tightening webbing, during operation, only the tightening webbing needs to be pulled from both sides to complete the locking of the back part of the shoe on the instep, and the loose webbing can be directly pulled up to loosen the back part to release the tightening webbing, but the user is troublesome to tighten the first tensioning belt and the second tensioning belt, and the structure is complicated.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model patent can be understood according to specific circumstances.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] according to Figures 1 to 7 A snowshoe binding comprises a base 1, a front cover 2, a front end of the base 1 being fixedly connected to the front cover 2 to form a toe portion 30, the improvement of which is that a tensioning belt assembly 3 is extended from the rear end of the front cover 2, tensioning ring components 4 are respectively distributed on both sides of the rear of the base 1, the tensioning belt assembly 3 passes through the tensioning ring components 4 to form a shoe body portion, a self-locking roller buckle 5 is fixed to the rear end of the tensioning belt assembly 3, and the tensioning belt assembly 3 is retractably fixedly connected through the self-locking roller buckle 5 to form a heel portion.

[0027] The tensioning belt assembly 3 includes a first tensioning belt 6 and a second tensioning belt 7. The tensioning belt assembly 3 and the front cover 2 can be integrally formed or fixedly connected in parts. Integrally formed means that the first tensioning belt 6 and the second tensioning belt 7 of the tensioning belt assembly 3 and the front cover 2 are formed into an integral structure through a plastic molding process. Conversely, fixedly connected in parts means that the first tensioning belt 6 and the second tensioning belt 7 of the tensioning belt assembly 3 and the front cover 2 are formed into independent parts through a plastic molding process and then fixed by riveting. The rear end of the first tensioning belt 6 is fixed with a self-locking roller buckle 5, see Figure 5 The self-locking roller buckle 5 has a wrench 22 with a torsion spring, and a positioning convex point 20 is arranged on the inner side of the wrench 22. The wrench 2 is rotatably fixed on the lock body 23 through an axle pin 24. The lock body 23 is U-shaped when viewed horizontally from above, and is arranged with a connecting column 14, thereby forming a lock hole 25 for the second tensioning belt 7 to pass through. The torsion spring keeps the wrench 22 in a downward trend, and can cooperate with the positioning hole 21 on the second tensioning belt 7 to achieve the telescopic connection and fixation of the first tensioning belt 6 with the second tensioning belt 7 through the self-locking roller buckle 5. By pulling the second tensioning belt 7, the function of tightening the heel is achieved. The outer wall of the connecting column 14 inside the self-locking roller buckle 5 is covered with a rubber sleeve 15, thereby reducing friction and facilitating the extension and retraction of the tensioning belt assembly 3. The tensioning ring component 4 and the base 1 are also integrally formed or fixedly connected in parts. The tensioning ring components 4 are distributed on the left and right sides of the base 1 and a fixing ring 8 is arranged on the top. The fixing ring 8 is a part of the outer wall that protrudes outward and is integrally formed or is fixedly connected in parts. In this embodiment, the outer wall of the tension ring part 4 is partially protruded outward and the fixing ring 8 is integrally formed. Of course, the fixing ring 8 can also be formed separately as a part and fixed to the outer wall of the tension ring part 4 with rivets 26 or glue. Figure 6 It can even be that the top of the tension ring component 4 has a bent extension 27, which is folded outward and fixed to the outer wall of the tension ring component 4 with rivets or sutures 28 to form a fixing ring 8. Figure 7 The fixing rings 8 on both sides cooperate with the first tensioning belt 6 and the second tensioning belt 7 respectively, and the first tensioning belt 6 and the second tensioning belt 7 pass through their respective fixing rings 8, thereby forming the shoe body part.

[0028] The top of the base 1 is provided with friction strips 9 and spurs 10, which cooperate with the active shoes to increase the friction. The front cover 2 and the tension band assembly 3 are fixed by riveting, that is, the front cover 2 is provided with a fixing groove 11, and the corresponding tension band assembly 3 is provided with a fixing hole 12. A metal part 13 such as a rivet passes through the fixing hole 12 and the fixing groove 11 to achieve riveting fixation. The tension band assembly 3 is a cross type. When the tension band assembly 3 is fixedly connected in parts, the front cover 2 is fixed with the first tension band 6 and the second tension band 7 by riveting. The rear part of the front cover 2 is provided with a fixing groove 11, and the front end of the corresponding first tension band 6 and the second tension band 7 is provided with a fixing hole 12. The metal part 13 passes through the fixing hole 12 and cooperates with the fixing groove 11 to achieve the fixed connection between the front cover 2 and the first tension band 6 and the second tension band 7, thereby forming a general X shape.

[0029] A fixing belt 16 is riveted at the bottom of the base 1, and both ends of the fixing belt 16 pass through fixing slots 18 at both ends of the snowboard 17 to achieve a fixed connection effect. A gripping plate 19 is also fixed between the fixing belt 16 and the base 1 by riveting. The snowboard 17 and the gripping plate 19 are made of metal materials. The base 1, the front cover 2, the tensioning belt assembly 3, and the tensioning ring component 4 can be made of plastic rubber materials or leather materials.

[0030] When the user uses the product, he only needs to put on the sports shoes, place the sports shoes at the toe portion 30 between the base 1 and the front cover 2, lift the tensioning belt assembly 3 to wrap the heel of the sports shoes, pull the second tensioning belt 7 with fingers to pull the excess length of the second tensioning belt 7 out of the self-locking roller buckle 5, so as to wrap the sports shoes. When the user moves the sports shoes, the snowboard 17 will also be driven to move, which is very convenient and quick to use.
