Abstract

An ice skate boot having two blades has blade mount fittings installed, so as to be freely movable, on coupling sections in the front and back of a skate boot frame. A blade bending cam unit is between the blade mount fittings. The blade bending cam unit has a mechanism to bend the blades mounted on the right and left simultaneously by way of horizontally tilting the skate boot. By way of the bending mechanism, the blade describes an arc having a center in the direction of the incline of the leg, and the ice skate boot slides on the ice along the arc.

Description

Ice skate shoes

∙ It relates to the mechanical technology of ice skates with two blades.

In normal ice skating with one blade, beginners are difficult to get used to because skates are tilted sideways, and skill is required to stand upright. In the first place, a person's feet have strong muscles that raise and lower their toes, and are muscles that are mainly used in athletics, such as running and jumping. Compared to that, the muscles that move the legs to the side are weak, and sometimes it is a weak point to turn over and sprain. Therefore, the figure skates that are brilliantly charmed are blood-trained training, and it cannot be said that a single-blade skate fits your foot.
In conventional eye skating, the bending of the blade has become an instability factor for skating, so it has been improved. For example, for speed skating, the bending of the blade has a pipe-like bulge. I lost it.
A conventional ice skate having two blades has two blades as disclosed in Japanese Utility Model Publication No. Sho 53-109975. Therefore, when the bottom surfaces of both blades are in contact with the ice surface, the skates in the horizontal direction are used. The inclination of the shoe is fixed. Otherwise, the blade on one side becomes an irregular ice skate that floats.

Publication number JP2011-5242

FIG. 1 is a top view of the skate shoe 1 on the right foot and shows the bending of the blade. In (a), when the skate shoe 1 is tilted to the left, the blade 2 turns in an arc so that the blade 2 is centered on the left. Naturally, the course of the skate advances so as to turn in the direction of the arrow 17, that is, in the left direction. (B) shows a state in which the skates 1 are standing vertically. The blade 2 is in a straight line and the traveling direction is also straight. (C) In the state where the skates 1 are tilted to the right, the blade 2 is drawn in an arc so that the center is formed on the right, and the traveling direction is also turned to the right.
FIG. 2 is a view of the skate from behind, corresponding to FIG. 1, and FIG. 2A shows the skate 1 tilted to the left and the blade 2 is bent. In (b), the skates 1 are upright and the blades 2 are straight. (C) shows that the skate 1 is tilted to the right and the blade 2 is bent.
Thus, the stability of the foot can be obtained by having the two blades 2, and the disadvantages of the ice skate having the two blades 2 can be wiped off, and the skate 1 can be freely tilted and slid. Even in this case, the two blades 2 are in close contact with the ice surface while drawing an arc, and can slide along a curve along the arc. The principle is an ice skate that bends the two blades 2 into an arc and slides along the arc, and the following is the mechanism that realizes the principle. The interval between the two blades is 2 cm or more and 25 cm or less.

FIG. 3A is a view of the skate shoe 1 as viewed from the rear. The skate shoe 1 is integrated with the frame 3 joined to the shoe sole in a vertically standing state, and is a joint circle fixed to the frame 3. One of the movements is connected to the blade fixing bracket 7 through the rod 18 so as to be free to move, and the other is when the blade 2 is bent. Since the space | interval of the braid | blade fixing metal fitting 7 in front and back of a leg becomes narrow, it becomes a free movement of the vertical direction of a leg. Then, the left and right blades 2 are fixed to the blade fixing bracket 7, and the blades 2 are in contact with the ice. 4B is a cross-sectional view 25 of FIG. 4, and the blade bending cam portion 4 integrated with the frame 3 is located in the middle of the blade fixing bracket 7 at the front and rear of the skate shoe 1. The blade bending cam portion 4 is connected to a blade bending rod 6 so as to move freely, and the blade bending rod 6 is connected to the left and right blades 2. (C) is a view in which the skate shoe 1 is tilted to the left, the position of the blade fixing bracket 7 does not change. The blade bending cam portion 4 moves to the right along with the tilt of the skate shoe 1 via the blade bending rod 6. Then, the blade 2 is bent by pushing the blades 2 on the left and right in the right direction. (D) is a view in which the skate 1 of (b) is tilted to the left, and shows how much the blade 2 is bent by the tilt of the skate 1 (b) and shows the blade deformation 26. This ice skate shoe utilizes the repulsive force against the bending of the blade 2, and if no lateral force is applied, the blade bending cam portion 4 is pushed by the repulsive force of the blade 2 via the blade bending rod 6, and the skate shoe 1 is Stand upright. Because the mechanism is simple, it becomes a light and light ice skating shoe.
FIG. 4 is a side view of the skate shoe 1 and shows that there is one blade bending cam portion 4 at the center of the blade fixing bracket 7 before and after the longitudinal axis of the foot. The long axis from to the heel is the vertical axis, the fingertip side is the front, and the heel side is the rear. The short axis on the right and left of the foot is the horizontal axis. The distance between the front and rear blade fixing brackets is set to be 7 cm or more and 45 cm or less between the front and rear, with the center from the tip of the foot vertical axis to the heel.

FIG. 5 shows that there are two blade bending cam portions 4. In this case, the connecting portions where the two blade bending cam portions 4 and the blade bending rod 6 are moved slightly in the longitudinal direction of the foot. When the blade 2 is bent more than when it is straight, the space between the front and rear blade bending rods 6 is reduced. The arrangement of the two blade bending cam portions 4 is such that the distance between the blade fixing bracket 7 in front of the longitudinal axis of the foot and the blade bending cam portion 4 in the front is fixed to the blade bending cam portion 4 in the rear and the blade fixing in the rear. The distance from the metal fitting 7 is the same. In addition, the space | interval between the blade bending cam parts 4 before and behind the vertical axis | shaft of a leg shall be 3 cm or more. Since there are two blade bending cam portions 4, when the weight is applied to the rear blade fixing bracket 7 and the skate shoe 1 is tilted, the blade bending cam portion 4 works only on the rear side of the foot and emphasizes the rear side. Can bend and slide along its arc. That is, since the blade fixing bracket 7 and the blade bending cam portion 4 on the front and rear of the longitudinal axis of the foot can be individually emphasized and used, more complicated sliding can be enjoyed.

FIG. 6 shows two examples in which the tilt adjusting elastic member 5 is installed. (A) arranges the inclination adjusting elastic member 5 so as to sandwich the left and right blade fixing member arm portions 15 of the blade fixing member 7, and is fixed to the frame 3 respectively, and the upper inclination adjusting elastic member 5 and the blade fixing member arm portion. 15. It is fixed with a screw that penetrates the lower inclination adjusting elastic member 5. Since the skate shoes 1 are upright, there are no deformations in the four elastic adjustment members 5 for tilt adjustment. In addition, it is illustrated that the recess of the frame 3 and the blade fixing bracket head 23 are connected so as to move freely. (B) has shown the state in which the skate 1 inclines to the left. The left upper tilt adjusting elastic member 5 is compressed and the lower tilt adjusting elastic member 5 is extended. Further, the upper inclination adjusting elastic member 5 on the right side is extended, and the lower inclination adjusting elastic member 5 is compressed. Since the inclination adjusting elastic material 5 does not extend, the long inclination adjusting elastic material 5 is previously attached with a screw. Also, rubber-like materials, coil springs, leaf springs, and air springs can be considered as the tilt adjusting elastic material.
(C) is a diagram in which the inclination adjusting elastic material 5 on the left and right blade fixing bracket arm portions 15 is the same as (a), and the lower part is replaced with an inclination adjusting spring 19 of a coil spring. The skate 1 is vertical and there is no distortion in the left and right tilt adjustment elastic material 5 and the lower tilt adjustment spring 19. (D) shows that the left inclination adjusting elastic member 5 is contracted while the skate 1 is inclined to the left, and the inclination adjusting spring 19 under the elastic member 5 is extended. Further, the right inclination adjusting elastic member 5 is extended, and the lower inclination adjusting spring 19 is compressed. The ice skate shoes of the mechanisms (a) and (b) become stable ice skate shoes for skating because the skate shoes are slightly tilted and a strong regulation works immediately. (C) and (d) Since the ice skate of the mechanism is more relaxed, the skate shoe 1 becomes easier to tilt and becomes a bolder ice skating shoe for skating.
FIG. 7 shows that there is one blade bending cam portion 4 at the center of the blade fixing bracket 7 on the front and rear of the vertical axis of the foot in the ice skates of FIGS. 6 (a) and 6 (c). Since there is only one blade bending cam portion 4, the ice skating shoe for stable skating can be obtained.

FIG. 8 shows that there are two blade bending cam portions 4 between the blade fixing brackets 7 at the front and rear of the vertical axis of the foot in the skate 1 of FIGS. 6 (a) and 6 (c). Also in this case, the play of the connecting portion between the blade bending cam portion 4 and the blade bending rod 6 includes play that moves back and forth in the longitudinal direction of the foot. The ice skates with this mechanism can emphasize the bending of the blade 2 separately around the longitudinal axis of the foot, so that more sophisticated skating can be enjoyed.

FIG. 9 shows another example in which a mechanism in which the axles of the wheels on the left and right are turned by the lateral inclination of the skates on the roller skates. There is an elliptical pipe frame 9 joined to an elliptical pipe frame support bracket 8 at two positions in the longitudinal direction of the foot on the sole of the skate 1, and a blade at the end of the elliptical pipe frame 9, that is, the armpit. The blade support bracket 10 which has the support bracket deflector 16 and the blade support bracket deflector 16 sandwiches the inclination adjusting elastic member 5 and moves by the blade support bracket deflection shaft 22. On the other hand, at the front part of the elliptical frame, there is a slite joint 11 that slides back and forth while adhering so as to wrap around the elliptical pipe frame 9, and a blade support bracket deflector 16 is joined to the front end part of the slide joint 11. The blade support bracket deflector 16 is connected so that the blade support bracket 10 is moved by a blade support bracket deflection shaft 22 with the inclination adjusting elastic member 5 interposed therebetween. As shown in FIG. 10, blade support bracket arms 21 extending in the horizontal direction of the foot extend to the left and right of the front and rear blade support brackets 10, and the blade 2 is a set screw that passes through the blade idler hole 13 formed in the blade 2. 12 is connected to the blade support arm 21 so as to move with the blade stopper washer 20 interposed therebetween.
FIG. 10 is a simplified view of the skate shoe seen from above with the fingertip direction of the skate shoe 1 of FIG. 9 in front. (A) is a figure in which the skates are tilted to the left, and the weight is naturally applied to the left side of the shoes. Since the blade support bracket deflector 16 at the front and rear of the foot follows the blade support bracket deflection shaft 22 shown in FIG. 9 and the blade support bracket 10 is deflected, the blade support bracket arm is inclined and connected to the blade 2. As a supplement to the bending force at that time, the set screw 12 that moves along the blade idler hole 13 shown in FIG. 9 and presses the blade stop washer 20 moves, and the blade 2 is bent. Follow the bent arc in the direction of the arrow. (B) is a state in which the skate 1 is vertical, and naturally the blade 2 is a straight line and advances straight. In (c), the blade 2 is bent opposite to (a) with the skate 1 tilted to the left, and proceeds in the direction of the arrow according to the arc. In the ice skating shoe of FIG. 9, the role of the brace bracket 10 installed in the middle of the blade brace 10 at the front of the longitudinal axis of the foot connected to the blade 2 and the braid 10 at the rear is the blade. This mechanism is still unfinished and imagined to resemble the arcs of the blades 2 on the left and right when 2 is bent.

The figure which shows the relationship between the inclination of skate shoes, the bending of a braid | blade, and the advancing direction. The figure which looked at the skate shoes of FIG. 1 from back. The figure which explained mechanically how the inclination of skates bent the blade. The figure which has one blade bending cam part. The figure which has a blade bending cam part two places. The change figure of an inclination adjustment elastic material when a skate shoe inclines with the perpendicular | vertical in 2 examples equipped with the inclination adjustment elastic material. In the two examples of FIG. 6, a skate shoe with one blade bending cam. In the example of FIG. 6, skate shoes with two blade bending cams. Side view of a skate, another example of bending the blade by another mechanism. The figure which shows the relationship between the inclination of the skate of FIG. 9, the bending of a braid | blade, and the advancing direction.

6 (c) is the best mode to be implemented. The reason is that the property of the rubber-like material considered as the material of the inclination adjusting elastic material 5 is that resistance suddenly increases depending on the degree of crushing. The greater the inclination of the shoe, the more the weight is biased and the stronger the force. The properties of rubber-like materials are suitable for offsetting that force. Similarly, Fig. 6 (a), which uses an elastic material, can be countered by softening the elasticity of the rubber-like material, in which the rubber-like material resists the inclination at the same time in two places. I am concerned that the resistance will be too great and lose lightness. Therefore, the combination of a rubber-like material and a coil spring-like elastic body is considered optimal.

Ice skates are playground equipment that people love, and the provision of new skates that stabilize their feet and lightly swing along the arc shaped by the blade will increase the number of enthusiasts and increase the employment and profits of the manufacturers.
