Background technology

Many people use snowshoe so that when winter, heavy snow covered this area in the walking of rugged border district.According to the latitude and the height above sea level of this area, snow can often gather one foot or the darker degree of depth.The unusual difficulty of walking in the accumulated snow of this degree of depth because people's pin is absorbed in one foot or the darker snow, makes the people need consume considerable energy its pin is carried away this snow hole to carry out another step.Therefore, every of many people wear a snowshoe when walking in the such kind of area, and so that its pin is floated on the snow face, the pin that promptly prevents the people is absorbed in the snow more than six inches.

Fig. 1 is the perspective view of conventional snowshoe 10.This snowshoe 10 comprises people's distribution of weight greater than the base plate 12 on the snow face (not shown) area of its footprint area be used to support people's weight and prevent the obviously framework 14 of distortion of this base plate during when distribution people's weight.This base plate 12 is the protrusion thin slice 16 by this base plate 12 of reeling around the part of this framework 14 and should protrude thin slice and be fixed in this framework 14 and this base plate 12 is fixed on this framework 14 as shown in Figure 2 usually.The cross section of this framework be as shown in Figure 2 usually circle and can be hollow as the pipe sample, or solid as the pole sample is so that this framework has desirable strength and stiffness, with the weight that supports the people and prevent base plate 12 distortion.This snowshoe 10 also comprises buckles bolt 18, snowshoe is fastened (not shown) on the boots on people's pin.This button bolt 18 is installed on the framework 14 usually and comprises tape 20 and clasp 22 can the mode of unclamping to link together, takes off this snowshoe 10 so that people can fasten snowshoe 10 on people's boots and from this boots securely.This tape 20 and clasp 22 also make the people snowshoe 10 can be fastened on the boots of different size.

Regrettably, this snowshoe 10 has some problems.Though this snowshoe 10 can be worked in powder snow well, this snowshoe 10 often can not provide enough adhesive force when being used to walk on the hard snow and ice of compacting.This framework 14 often can not enter this surface when on the hard snow and ice of walking in compacting, and therefore many snowshoes and surperficial contacting are this frameworks 14 and the contacting of this surface.Because framework 14 has circle or square-section, this framework 14 is easy to slide along this surface, and this makes when the surface of hill has the hard snow of compacting or ice, contour, goes up a hill and goes down the hill to walk all very difficult.

Another problem of this snowshoe 10 is to buckle bolt 18 to be difficult to operate with glove hand.For snowshoe 10 is fastened on people's boots, this people must untie tape 20 from clasp 22, buckles in the bolt 18 so that the people can be easy to put its boots into this.But must back this tape 20 be pierced in this clasp 22 with the descendant, so that snowshoe 10 is fastened on boots.Make of glove hand that these are normally very difficult and often unsuccessful.The another kind of method that snowshoe 10 is fastened on people's boots can be to move clasp 22 and do not untie this clasp 22 from this tape 20 towards the end of this tape 20.But people must slide into its boots this and buckle in the bolt 18 then.This is also very difficult usually and can fail, because have the vamp (gator) that the tape of clasp 22 may stumble people's boots and often be worn and torn by snowshoe.
