Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a so-called clap type skate shoe in which a boot of the skate shoe can be detached from a blade on a heel side.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a skate shoe has a boot 1 attached to a user's foot and a blade 2 which comes into contact with an ice surface below the boot 1 in an integrated manner. It was common. However, in recent years, so-called clap type skating shoes, in which the heel side of the boot 1 can be detached from the blade 2, have come to be used.

As shown in FIG. 6, in this clap type skate shoe, the toe side of the boot 1 is supported on a blade 2 via a support 3, and the support 3 is provided with an upper (boot side) 3 A and a lower (boot) side. Side) 3B is rotatable via a hinge 3C. Further, the heel portion 4 extending downward from the rear end of the boot 1 comes into contact with a support 5 fixed on the blade 2 so as to be detachable.

With such a configuration, the heel part 4 naturally separates from the support post 5 when the ice surface is kicked by the skate shoes on the rear foot side during skating, or when a load is applied to the toe side such as when cornering. As a result, since the bottom surface of the blade 2 keeps completely in contact with the ice surface, the force of kicking the ice surface by the skate shoes does not weaken.

[0005] A spring 6 extends from the lower portion 3 B of the column 3, and the tip is fixed to the back surface of the boot 1. Due to the repulsive force of the spring 6 when the boot 1 rotates, the heel portion 4 separated from the blade 2 is pulled back to the blade 2 again.

[0006]

However, the conventional clap type skate shoes shown in FIG. 6 have the following problems.

First, as described above, since the rotation of the boot 1 is pulled back toward the blade 2 by the repulsive force of the spring 6, when the heel portion 4 that has been pulled back hits the strut 5, an impact is applied. This may cause discomfort and fatigue to the user of the skate shoes.

Secondly, in a skate competition, quick footwork or extremely strong kicking force may be required, such as at the time of a start dash, but in such a case, the heel portion 1 rather has the blade 2 It is more convenient not to leave the side. Therefore, for example, during normal skating operation, the resistance of the rotation of the boot 1 is not given, while at the time of start dash, the heel part 4 is hardly separated from the blade 2 side. It is necessary to deal with such problems. However, in this conventional clap-type skate shoe, it is not possible to adjust the ease with which the heel part 4 is separated from the blade 2 in accordance with the skate operation (the rotation speed and the rotation angle of the boot 1).

The present invention has been made in view of such a problem.
It is an object of the present invention to provide an apparatus that does not generate an impact when the heel returns to the blade side, and that can appropriately adjust the ease of rotation of the boot in accordance with the skating operation.

[0010]

According to a first aspect of the present invention, there is provided a skate shoe comprising a blade and a boot rotatably supported on the blade so that a heel portion can be separated from the blade side. A swing arm having one end rotatably supported on the blade side and a boot with the toe side facing the rotation fulcrum fixed to the upper surface; and an initial position where the swing arm is not rotated from the blade side. A stopper that supports the vicinity of the other end of the swing arm, a damper whose both ends are rotatably supported on the swing arm and the blade side so as to extend or contract in accordance with the rotation of the swing arm, and Spring means for urging the swing arm in the direction of pulling back to the blade side.

In a second aspect of the present invention, the swing arm and the damper are substantially parallel at an initial position of the swing arm rotation.

According to a third aspect of the present invention, a bracket is fixed to the blade, side walls are provided on both sides of the long plate-shaped main body of the swing arm, and the bracket is covered from both sides by these side walls. In the above, the swing arm is pivotally supported by the bracket, while a recess is formed in the bracket, an opening is formed in the main body of the swing arm in accordance with the position of the recess, and the damper is formed in a space extending from the recess to the opening. To accommodate.

According to a fourth aspect of the present invention, the blade of the damper is configured such that the damping force of the damper acts on the swing arm such that the arm of the moment acting on the swing arm decreases as the swing arm rotates away from the blade side. A pivot point on the side is arranged.

According to a fifth aspect of the present invention, the pivot point of the damper on the blade side is disposed near a position below the pivot point of the swing arm.

In a sixth aspect of the present invention, the damping force of the damper changes according to the turning position of the swing arm.

According to a seventh aspect of the present invention, the damping force characteristic of the damper is set so that the damping force of the damper in the initial range of rotation of the swing arm is larger than the damping force of the swing arm beyond the initial range. I decided.

[0017]

According to the first aspect of the present invention, the swing arm rotates with respect to the blade in response to the skate operation of the user, and the heel side of the boot fixed on the swing arm rises with respect to the blade. . As a result, even when the heel side of the boot is raised, such as when weight is applied to the toe side, the blade remains horizontal to the ice surface and complete contact with the ice surface is maintained, but in this case, In addition, an appropriate resistance is given to the rotation of the swing arm (boot) by the damping force of the damper that expands and contracts with the rotation of the swing arm. In other words, when quick footwork is required, such as during a start dash, the swing arm's rotation speed increases and the damper's expansion and contraction speed also increases, so a strong damping force is generated in the damper, and the boot is naturally attached to the blade side. To keep a strong kicking force. On the other hand, during normal skating, the swing arm's rotation speed is relatively low, so the damping force generated in the damper is also relatively small, the boot is easily separated from the blade side, and excessive resistance to skate operation occurs. There is no.

Further, when the swing arm is pulled back by the spring means and returns to the initial position, the damping force of the damper weakens the swing momentum of the swing arm, thereby preventing the swing arm from hitting the stopper vigorously. Therefore, even when the boot returns to the blade side, no impact is transmitted to the user of the skate shoe, and no discomfort or fatigue is given to the user of the skate shoe.

Further, since the swing arm and the damper are directly supported on the blade side, the number of movable members is minimized. As a result, the size and weight of the skate shoes can be reduced, and the frictional resistance and play between the movable members are small, and the rotation of the boot can follow the movement of the user with good responsiveness.

In the second aspect, the damper and the swing arm are arranged so as to be substantially parallel to each other at the initial position of the swing arm. Therefore, the pivot point of the damper on the bracket side is naturally set to the pivot point of the swing arm. When the swing arm rotates, the stroke of the damper can be prevented from becoming unnecessarily large. In addition, while securing the length of the damper enough,
The swing arm and the damper can be compactly arranged in a small space.

According to the third aspect of the present invention, the swing arm is wrapped around the bracket on the side wall, and the damper is arranged in a space extending from the recess of the bracket to the opening of the swing arm. Can be arranged compactly. In addition, the swing arm having the opening formed in the plate-shaped main body and the bracket having the recess can be reduced in weight by the amount of the opening and the recess, so that the skate shoes can be reduced in size and weight.

In the fourth and fifth inventions, the arm length of the moment given to the swing arm by the damping force of the damper, that is, the length of the vertical line dropped on the axis where the damper expands and contracts from the pivot point of the swing arm is Therefore, even if the damping force of the damper is constant irrespective of the expansion / contraction stroke, the moment given by the damper to the rotation of the swing arm is smaller than that of the swing arm. It can be reduced as the rotation angle increases. As a result, when the rotation angle of the boot is small, such as during a start dash,
The damping force of the damper keeps the boot and the blade relatively integrated to ensure a strong kicking force, while the damping force of the damper increases when the turning angle of the boot becomes large, such as during steady running. The skating action is not overly resistive.

According to the sixth and seventh aspects, when the rotation of the boot is within the initial range, such as during a start dash, the boot and the blade are relatively integrated by the damping force of the damper,
While strong kicking force can be secured, when the boot rotates beyond the initial range, such as during steady running, the damping force of the damper exerts little resistance on the boot, and excessive resistance is added to the skate operation Absent.

[0024]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 3 show an embodiment of the present invention. In these figures, the boots 1 of the skate shoes are omitted.

As shown in the figure, a bracket 10 is fixed to the cylindrical portion 2A above the blade 2 by bolts 7 and 8. A bearing bush 11 passes through the bracket 10 at a predetermined position in a direction perpendicular to the blade 2. The bearing bush 1 is located near the base end of the swing arm 12.
The bracket 10 is rotatably supported by a bracket 10 via a shaft 13 housed in the bracket 1.

The main body of the swing arm 12 is in the shape of a long plate, and on the base end side, side walls 12A extend from both sides and have a U-shaped cross section. Bracket 10
Are covered on both sides by these side walls 12A, and the above-mentioned shaft 13 extends from these side walls 12A to the bracket 10.

A boot fixing bolt 14 is fixed to the swing arm 12 near the base end, and a boot fixing bolt 15 is fixed to the swing arm 12 near the distal end via nuts 16 and 17, respectively. The toe side of the boot 1 (not shown) is fixed to the boot fixing bolt 14, and the heel of the boot 1 is fixed to the boot fixing bolt 15. Thus, the boot 1 rotates relatively to the blade 2 together with the swing arm 12, and the heel side of the boot 1 is separated from the blade.

An elongated hole-shaped recess 12C is formed in the lower surface 12B at the tip of the swing arm 12. A nut 17 for fixing the boot fixing bolt 15 is located on the bottom surface of the recess 12.

A stopper 20 is fixed to the cylindrical portion 2A of the blade 2 via a bolt 21 so as to be located below the concave portion 12C. The stopper 20 has a convex portion 20A on an upper portion, and the convex portion 20A is in an initial position where the swing arm 12 is not rotated with respect to the blade 2 (the heel of the boot 1 is not separated from the blade side). , Recess 20A. At this time, the step portion 20B on the side of the convex portion 20A abuts on the lower surface 12B of the distal end of the swing arm 12 to support the distal end of the swing arm 12. The height of the projection 20A is set to such a degree that the tip does not contact the nut 17.

An opening 12D is formed near the center of the swing arm 12 body. And this opening 12D
A recess 10A is formed in the bracket 10 below the bracket 10 and a damper 22 is disposed in the recess 10A (the damper 22 is not shown in FIG. 2). This damper 22
Is rotatably supported at one end to the bracket 10 via the pin 23 and at the other end extracted from the opening 12D to the arm 12 via the pin 24.

In this case, the pin 23 is disposed on the tip side of the swing arm 12 (heel side of the boot 1) with respect to the shaft 13,
The pin 24 is the swing arm 1 further than the pin 23.
2 is disposed on the tip side. The pin 23 is connected to the shaft 13
And below the line connecting the pins 24. As a result, when the swing arm 12 rotates about the shaft 13 with respect to the blade 2, the damper 22 rotates about the pin 23 in the direction in which it rises, and at this time, the distance between the pin 23 and the pin 24 increases. To give a damping force to the rotation of the boot 1. If the pin 23 is located below the line connecting the shaft 13 and the pin 24, as the swing arm 12 rotates with respect to the blade 2, the
Can be made to contract, thereby generating a damping force.

In the initial position of the swing arm 12, the damper 22 is disposed so as to be substantially parallel to the swing arm 12. Thereby, the swing arm 1
It is possible to prevent the stroke of the damper 22 from becoming unnecessarily large during the rotation of the second lever. In addition, the swing arm 12 and the damper 22 can be compactly arranged in a small space while ensuring a sufficient length of the damper 22.

A pair of springs 25 are provided on both sides of the damper 22.
(For example, coil springs) are arranged in parallel. One end of each of the springs 25 is attached to the mounting portion 26 of the bracket 10.
The other end is the mounting portion 27A of the swing arm 12, 2
7B. In this case, the mounting portion 26 is more swing arm 1 than shaft 13.
2 (the heel side of the boot 1) and below the line connecting the shaft 13 and the mounting portion 27A or 27B. Accordingly, when the swing arm 12 rotates so that the heel of the boot 1 is separated from the blade 2 side, the spring 25
Is stretched and urges the swing arm 12 to return to the initial position on the blade 2. Note that the attachment position of the spring 25 to the swing arm 12 is two of 27A and 27B.
The position of the spring 25 is such that the tension of the spring 25 can be adjusted by changing the mounting position.

Incidentally, the spring means is provided with the damper 22 as described above.
The swing arm 12 is not limited to the one provided in parallel with the shaft 2, and may be any as long as the swing arm 12 is pulled back to the blade 2 side, for example, a torsion spring is provided near the shaft 13.

Next, the operation will be described.

When skating with the skate shoes of the present invention, the swing arm 12 rotates about the shaft 13 as necessary, and the heel side of the boot 1 fixed on the swing arm 12 (the tip side of the swing arm 12). Is blade 2
Float against. Thus, even when the heel side of the boot 1 is raised, for example, when the weight is applied to the toe side, the blade 2 remains horizontal with respect to the ice surface, and complete contact with the ice surface is maintained.

By the way, a resistance based on the damping force of the damper 22 is applied to the rotation of the boot 1 (swing arm 12) in such a skate operation. Is relatively small, the expansion and contraction speed of the damper 22 is also small,
The resistance to the rotation of the boot 1 due to the damping force 2 is also small. Therefore, no excessive resistance is given to the skate operation.

On the other hand, when a large rotation speed is given to the boot 1 by quick footwork, for example, at the time of a start dash, maintaining the integrity of the boot 1 and the blade 2 helps the skating operation. In this case, it is desirable that the boot 1 has resistance to the rotation. On the other hand, in the present invention, when a high rotation speed is given to the boot 1, the expansion and contraction speed of the damper 22 increases accordingly. Also increases. For this reason,
The heel side of the boot 1 is less likely to float from the blade 2 side, and the integrity of the boot 1 and the blade 2 is naturally achieved.

Further, in the present invention, by setting the damping force characteristic of the damper 12, it is possible to set an appropriate resistance to the rotation of the boot 1 according to the rotation angle.

Specifically, for example, when the heel of the boot 1 starts to separate from the blade 2 side (when the rotation angle of the boot 1 is small), the boot 1 (swing arm 1)
While the damping force of the damper 22 is increased so as to give a large resistance to the rotation of 2), when the rotation angle of the heel of the boot 1 from the blade 2 is increased, the resistance to the rotation of the boot 1 is reduced. The damping force of the damper 22 is weakened. Accordingly, when it is desired to maintain the integrity of the boot 1 and the blade 2 such as at the time of a start dash, since the rotation angle of the boot 1 is still small, the heel of the boot 1 is unlikely to rise from the blade 2 side, and a strong kicking force is obtained. On the other hand, after the heel of the boot 1 is greatly lifted, such as during steady running thereafter, resistance to the rotation of the boot 1 is small, and excessive resistance to the skate operation can be prevented.

For example, as shown in FIG.
By appropriately setting the position of the pin 23, for example, by positioning the position of the pin 23, which is a pivot point on the blade 2 side, below the shaft 13, the damping force of the damper 22 is independent of the stroke of the damper 22. Even if it is constant, the moment given by the damper 22 to the rotation of the swing arm 12 can be reduced as the rotation angle of the swing arm 12 increases.

This will be described in more detail. As the swing arm 12 rotates, the center axis of the damper 22 rotates from the axis 30A to the axis 30B. At this time, the damping force of the damper 22 is the length of the moment arm applied to the swing arm 12, i.e. the length of the perpendicular dropped from the shaft 13 is a rotation fulcrum of the swing arm to the center axis of the damper 22, from X ₁ changes in X _2, gradually becomes shorter. As described above, by appropriately setting the position of the pin 23 with respect to the shaft 13 so that the arm length of the moment acting on the swing arm 12 decreases as the swing arm 12 rotates, as a result, Damper 2
2 gives the moment given to the rotation of the swing arm 12,
It can be made smaller as the swing angle of the swing arm 12 increases.

When the boot 1 returns to the initial position on the blade 2 side, the boot 1 is pulled back by the spring 25, and the damper 12 also gives an appropriate damping action to this pull-back operation. Thereby, the moment when the tip of the swing arm 12 is pulled back and hits the stopper 20 is reduced, and the impact transmitted to the user can be reduced. As a result, the user does not experience discomfort or fatigue due to the impact.

Further, in the present invention, the swing arm 12
And the end of the damper 22 is directly supported by the blade 2 via the bracket 10 (for example, without passing through a link mechanism or the like).
It is fixed on top. Thereby, the number of the movable members is minimized, the size and weight of the clap type skate shoes can be reduced, the frictional resistance between the movable members and the backlash are small, and the boot 1 can be moved with respect to the movement of the user. The turning operation can be followed with good responsiveness.

The swing arm 12 has a side wall 12A.
And the damper 22 is disposed substantially parallel to the swing arm 12 in a space from the recess 10A of the bracket 10 to the opening 12D of the swing arm 12. As a result, the entire swing arm 12, bracket 10 and damper 12 can be compactly arranged, and the swing arm 12
In addition, the weight of the bracket 10 can be reduced.
