The lower end of the leg pole is turnably connected with a foot member for grounding so as to face a direction of supporting a forward tilting posture of the leg post, and is provided with a cushion mechanism for allowing the turning of the foot member in the forward tilting posture while relieving a cushioning impact on the foot member in grounding, when walking on the tilt. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to stilts, and more particularly to elastic stilts.
[0002]
[Prior art]
A stilt, which is widely used as an easy-to-use exercise tool, has a basic structure including a leg having a predetermined length and a step for placing a foot fixed in the middle of the leg. Patent Literatures 1, 2, and 3 disclose techniques in which this stilt has an elastic force as a special function. This elastic stilt was invented for the purpose of increasing motility by enabling jump walking, and a spring is attached to the lower end of the leg rod below the step, so that "hopper" known as a jumping exercise tool The structure is as follows.

[Problems to be solved by the invention]
The above-mentioned conventional elastic stilts have a structure that jumps by the force of a spring for the purpose of walking at high speed, and is very difficult to ride. In view of the above, the present invention provides an elastic stilt that emphasizes not only jumping running but also ease of riding, and that can be enjoyed by anyone.
[0005]
[Means for Solving the Problems]
According to the present invention, in a stilt consisting of a leg rod of a predetermined length and a step for placing a foot fixed in the middle of the leg rod, at the lower end of the leg rod, the direction supporting the forward leaning posture of the leg rod is set. A cushioning mechanism that rotatably connects the grounding foot member and that allows the foot member to rotate in the forward tilt direction of the leg while buffering an impact applied to the foot member by landing when the stilt is walking. It is characterized by having been provided.
[0006]
According to this stilt, when walking, the foot member moves like a suspension that rotates while buffering the impact of landing by the shock absorbing mechanism, so that a soft walking sensation as if a human is walking on his toes can be obtained. Also, since the foot member can support the weight by touching the ground over a wide area, the forward movement of the leg rod is relatively slow due to the function of the shock absorbing mechanism. It is very comfortable and dull compared to stilts.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows an example of the stilts of the present invention. The stilt horse 1 has a straight leg 2, and a step 3 is fixed to the lower part of the leg 2 in the middle. Step 3 includes a toe clasp 3a for holding the toe side of the foot and a heel clasp b for holding the heel side, so that the foot is held so as not to come off.
[0008]
At the upper end of the leg bar 2, a grip portion 2a for holding by hand is formed by rubber coating or the like. On the other hand, a foot member 4 is rotatably attached to a lower end of the leg bar 2 by a hinge connection 4a (that is, an ankle). The foot member 4 is connected so as to protrude in a direction that supports the forwardly inclined posture of the leg bar 2, that is, in the present example, in a direction opposite to the mounting direction of the step 3.
[0009]
The foot member 4 and the leg bar 2 form an obtuse angle θ, and the rubber-coated toe portion 4b of the foot member 4 contacts the ground. To this end, the toe 4b is gently curved. One end of a buffer mechanism 5 is hingedly connected to an intermediate part (a part corresponding to the instep) of the foot member 4, and the other end of the buffering mechanism 5 is hingedly connected to the leg bar 2. The shock absorbing mechanism 5 of the present embodiment is constituted by a shock absorber composed of a hydraulic type, a pneumatic type, rubber, a spring or the like.
[0010]
The stilt 1 is designed to walk with the toe 4b of the foot member 4 grounded, and the shock mechanism 5 buffers the impact of the landing during the walking while the foot member 4 It turns in the forward tilt direction, that is, the direction in which the angle θ between the foot member 4 and the leg bar 2 becomes smaller. In other words, the leg bar 2 tilts forward (arrow X) relatively slowly while buffering the shock by the buffer mechanism 5.
[0011]
In this way, in a state where a person walks on the toe, it is possible to walk while tilting the leg bar 2 forward relatively slowly while absorbing the shock, and the ground contact area of the toe portion 4b is reduced. Since it can be wider than the tip area, the walking state is stable and it is easy to ride.
[0012]
FIG. 2 shows a modification of the stilt 1. In this example, the leg 2 is deformed into the shape of a "ku" in a portion above the step 3, so that the leg 2 is inclined forward as compared with the straight case in FIG. In addition, the grip portion 2a is formed in a hook shape so that the hand is hardly slipped off. Further, the toe portion 4b of the foot member 4 in this example is gently curved, and a rubber block is provided on the back side (that is, the ground surface) for cushioning and preventing slippage.
[0013]
FIG. 3 shows some modified examples of the foot member 4. FIG. 3A shows an example in which the toe portion 4b is separately fixed to the foot member 4 by the shaft 4c, and FIG. 3B shows that the toe portion 4b is further divided into two parts, This is an example of fixing by a shaft 4d. According to these examples, the angle and the degree of curvature of the toe portion 4b can be adjusted by the axes 4c and 4d. In both cases, a rubber block is provided on the sole as in FIG.
[0014]
FIG. 4 shows a number of modifications of the buffer mechanism 5. 4A shows an example in which a shock absorbing mechanism 5 of a shock absorber is provided between the foot member 4 and the leg bar 2 as in FIG. 1, and FIG. 4B shows one end of the shock absorbing mechanism 5 as a shock absorber. This is an example in which a hinge connection is made to the foot member 4 and the other end is hinged to the back side of the leg 2 (the side of step 3). The shock absorber may have any structure as long as the shock is absorbed by a hydraulic / pneumatic type, rubber, spring, or other means.
[0015]
4C and 4D show an example in which a shock absorber 5 of a shock absorber is provided via an arm. In the case of FIG. 4C, the arm 5a protruding from the step 3 side of the leg 2 is provided. One end of the shock absorbing mechanism 5 is hingedly connected, and the other end of the shock absorbing mechanism 5 is hingedly connected to one end of an arm 5c which is pivotally supported 5b on the leg member 2 side of the leg bar 2. The other end of the arm 5c is hinged to an arm 5d hinged to the foot member 4. In the case of FIG. 4D, one end of an arm 5b is hingedly connected to an arm 5a protruding from the step 3 side of the leg bar 2, and the other end of the arm 5b is connected to one end of a buffer mechanism 5 and one end of an arm 5c. Hinged. The other end of the arm 5c is hingedly connected to the foot member 4, and the other end of the buffer mechanism 5 is hingedly connected to the step 3 side of the leg bar 2.
[0016]
FIGS. 4E and 4F are examples in which urethane rubber is used as the buffer mechanism 5. In the case of FIG. 4 (E), a cushioning mechanism 5 made of urethane rubber is interposed between the arm 5a erected on the foot member 4 and the leg bar 2, and in the case of FIG. A urethane rubber buffer mechanism 5 is sandwiched between an arm 5a protruding from the step 3 and an arm 5b extending from the foot member 4 to the step 3 of the leg 2. Thus, an elastic body can be used as the buffer mechanism 5.
[0017]
In the example of FIG. 4G, one end of a shock absorbing mechanism 5 serving as a shock absorber is hingedly connected to the foot member 4, and the shock absorbing mechanism 5 is hinged at one end to the leg bar 2 above the foot member 4. Are hingedly connected to each other. The other end of the arm 5a is hinged to one end of the arm 5b, and the other end of the arm 5b is hinged to the foot member 4. In addition, the toe portion 4b of this example is a movable separate body that is supported by the foot member 4 at a pivot 4c, and the toe portion 4b is also provided with a urethane rubber buffer mechanism 6. This buffer mechanism 6 is sandwiched between an arm 6a and an arm 5b that are provided upright on the toe 4b.
[0018]
