Description

Technical description

The present invention relates to an instrument that assists in easily performing exercises such as stretching and twisting of a body. Background art

Various exercise aids have been devised and are commercially available, but there are problems such as complicated structure, large size, and high price. The present invention was made by considering whether a simple and inexpensive exercise assisting device could be made, focusing on cleaning tools such as mops, and thinking that it would be possible to improve this and use it as an exercise assisting device. . Disclosure of the invention

Problems to be solved by the invention

Exercises and gymnastics that involve stretching and torsion of the body tend to fall into the self-flow, and there is a problem that the body is not stable and causes an accident such as a fall.

Also, commercially available sports equipment is large and fixed, and is expensive and requires space. On the other hand, there is a risk of accidents due to the users coming into contact with each other when using them in a group because the users use them individually.

The present invention has been made in view of such problems, and it is an object of the present invention to provide an exercise aid that has a simple structure and is inexpensive.

Means for solving the problem

In order to achieve such a problem, the first problem solving means of the present invention includes a base, a support rod that can be extended and contracted in the axial direction, and one end of the support rod that is perpendicular to the base. It is composed of a coupling member that biases in any direction.

According to a second problem solving means, the support rod has a function that can be expanded and contracted, rotated, and fixed at an arbitrary position.

The third problem-solving means includes a base, a coupling member made of a cylindrical or columnar elastic material, a pipe-shaped first support rod having one end attached to the base by the coupling member, and the first A second support bar that is slidable from the other end of the support bar and is rotatably inserted; A fixing tool that can fix and release the second support bar at an arbitrary position with respect to the first support bar, and an area suitable for placing a palm, and a plurality of fingers can be inserted on the periphery. A plurality of protrusions provided at intervals, and a grip portion provided at an upper end of the second support rod.

According to a fourth problem solving means, the coupling member is configured to be attachable to and detachable from the base portion and the support rod by a fixing means.

In a fifth problem solving means, the coupling member is composed of a combination of an elastic member and a member that can deform the elastic member and develop a resistance force.

The invention's effect

According to the first problem solving means, the support rod can be expanded and contracted in the axial direction with respect to the base portion and can be rotated, and the force for urging the connecting member in the vertical direction is not so strong. For this reason, the function of the exercise assisting device is not the function of supporting the body, but the position of the body relative to the base, and the relationship between the angle of the support rod of the implement and the position of the base. The function that can be felt by touch and touch is the main function. This function allows the user to easily perform exercises such as stretching and twisting in a stable state while maintaining balance. Also, it is easy to understand the difference between how to move your body and how to move your instructor, so that you can learn the standard way to move your body.

In addition, the user moves with the base as a base point, and by naturally returning to the original position, it is possible to balance the amount of movement in the front / rear and left / right directions. This allows individual users to exercise within their own area, reducing the risk of contact between users when exercising in groups.

According to the second problem solving means, the length of the support bar can be adjusted according to the height by the function that can be fixed to an arbitrary length, and the body can be supported by holding an appropriate portion of the support bar. If the fixing function is loosened, the load on the coupling member can be reduced and the life of the coupling member can be extended.

According to the third problem solving means, when the base portion is placed on the floor, the support rod automatically becomes vertical, so that an appropriate position of the grip portion or the support rod can be secured by a function that can be fixed to an arbitrary length. The body can be held and supported, and while maintaining balance, exercises such as stretching and twisting of the body can be performed easily and stably. If the fixing function is loosened, not only can the gymnastic exercise take into account the operation of expanding and contracting the support rod, but also the load on the coupling member can be reduced and the life of the coupling member can be extended.

According to the fourth problem solving means, the coupling member can be exchanged and maintenance is facilitated. According to the fifth problem solving means, the structure can be simplified by eliminating the mechanically movable part, and the failure can be reduced. We can plan reduction.

1 Base 2 Support rod 3 Coupling member 4 Protrusion 1 b, 2 a Spherical recess and sphere that make up the universal joint mechanism 5 Grip The best mode for carrying out the invention

FIG. 1 shows an embodiment of the exercise assisting device according to the present invention. The bottom surface 1a is in close contact with the floor, or can be expanded and contracted on the upper surface of the base portion 1 which is in contact with a strong frictional force. One end of the support rod 2 that can be fixed to the mounting member 3 is attached via the coupling member 3, and is configured to swing around the coupling member 3.

In this embodiment, the coupling member 3 is configured as a universal joint mechanism in which a spherical concave portion 1 b formed in the base portion 1 is fitted with a spherical portion 2 a formed at the lower end of the support rod 2.

Further, a protrusion 4 made of a coasting material suspended from the base 1 is engaged with the center of the ball 2 a so that the support rod 2 is always urged so as to be perpendicular to the base 1. In this embodiment, The base 4 is constructed integrally with the base 1, but the same effect can be obtained even when an elastic material such as a coil panel is fixed to the base 1.

On the other hand, the support rod 2 is divided into two pieces 2 b and 2 c, and the base side piece 2 b can be expanded and contracted through the other piece 2 c as a pipe, and the closure 5 For example, a grip 6 is provided at the upper end of the support bar 2.

In this embodiment, in this embodiment, the closure 5 is loosened and the support bar 2c is expanded and contracted to adjust the grip 6 so that it is in use, easy to use and easy to use. Adjust and fix the length arbitrarily.

In this state, as shown in FIG. 2 (a), hold the grip portion 6 formed at the upper end of the support rod 2 in the hand, bend and stretch the body around the lower end of the support rod 2, or 2 When twisted as shown in FIG. 2 (b), the ball portion 2a constituting the coupling member 3 below the support rod 2 rotates in the recess 1b against the elasticity of the protrusion 4, and the grip portion 6 moves in a circle. This allows the user to perform torsional movements safely without losing balance.

When the movement is finished and the hand 6 is released, the protrusion 4 is restored in the vertical direction by its own elasticity, so that the ball 2a also returns to its original position and the support bar 2 is in a vertical state.

Further, in the above-described embodiment, the force that constitutes the coupling member 3 by the spherical portion and the hemispherical concave portion is rotated so that it crosses the base 1 horizontally in a cross and is positioned vertically as shown in FIG. Even if the configuration in which the moving shafts 40 and 41 are arranged, the support rod 2 can be attached to the base 1 so as to be rotatable. '

In the above-described embodiment, the universal joint mechanism is used as the coupling member 3 that rotatably supports the support rod, but the base 1 is made of an elastic material such as rubber as shown in FIG. Even if it is configured, even if the bellows-like protrusion 1c is formed at the position where the support rod 2 is attached, and the lower end of the support rod 2 is engaged and fixed to the recess 1d formed in this, the elastic deformation of the protrusion 1c The support rod 2 can be pivotally attached to the base 1 by using.

Preferably, when the protrusion 1c is made of a viscoelastic material, for example, rubber mixed with lead particles, the viscoelastic material can be rotated by the elasticity, and a rapid repulsive force can be suppressed by the viscosity. Can do.

FIG. 5 shows another embodiment of the present invention. In this embodiment, the support rod 2 is configured as a two-body structure, while the one 2b is configured by a pipe and is attached to the base 1. It is attached via a coupling member 3 that has elasticity like a cylindrical or rod-like rubber and has a certain degree of viscosity. The other 2c is slidably inserted into the one 2b. Has been. As shown in Fig. 6, Bonoleto 3 2 and Nut 3 3 are formed on the upper and lower ends of the rubber body 31 constituting the coupling member 3 with a hard material such as metal, and face each other. If the support rod 2 b and the base 1 are each provided with nuts 3 4 and bolts 3 5, they can be easily replaced.

Further, as shown in FIG. 7, the upper end of the support rod 2b attached to the base 1 is made of an elastic material, for example, a polymer material, and a split groove is formed, and a screw is formed on the outer periphery. The first closing tool 51 is fixed, and is a ring shape that is loosely fitted to the other supporting bar 2c, and the second closing tool 5 2 is formed with a screw on the inner periphery. The length can be adjusted and fixed arbitrarily.

A grip 6 is provided at the upper end of the second support rod 2c. The grip 6 is a substantially circular shape having a diameter of 5 to 10 cm when viewed from the top as shown in FIG. Two protrusions 61 and 62 are formed, each having a space suitable for placing the palm of the hand, and having a space for accommodating a group of strong index finger, middle finger, and ring finger together.

In this example! When the height of the support bar 2 is adjusted so that the position of the grip part 6 becomes an appropriate height and fixed with the closing tool 5, the support bar 2 is stabilized as an auxiliary tool in the same manner as in the above embodiment. You can do gymnastics.

On the other hand, when the closure 5 is loosened so that the upper support bar 2c is slidable relative to the other support bar 2b, the upper support bar 2c as shown in Fig. 2 (c). It is possible to perform gymnastic exercises while extending and retracting c. According to this, since the load on the support rod 2b due to gymnastics is reduced by sliding and relative rotation with the support rod 2c, the base 1 and The load on the coupling member 3 can be reduced.

When the gymnast exercises while sliding the support rod in this way, the second fixture 52 is pulled up to the upper end, and the cross section as shown in FIG. 9 (a) is located below the fixture 52. When the C-shaped intermediate fixing tool 53 is attached to prevent the second closing tool 52 from moving up and down (Fig. 9 (b)), the first and second support rods 2b are slid. 2 Closure 5 1 and 5 2 can be prevented from colliding and preventing damage and deterioration. The intermediate fixture 53 may be provided with a screw that matches the screw of the second fixture 52 if necessary.

In addition, since the recess 1e is formed at the bottom of the base 1, the protruding part of the base 35 of the base 1 is accommodated in the HO 1e even when stacked, and can be stacked stably. It is also suitable for use in large quantities.

In the above embodiment, the length of the support bar is adjusted by expansion and contraction. As shown in Fig. 10 (a), several small pieces 2c 'having the same diameter as the second support rod, for example, about 5 cm in length, are prepared and added according to the height. 2 The number of c 'may be adjusted.

That is, as shown in FIG. 10 (b), the small piece 2c 'is formed with a screw hole 2d' at one end and a screw rod 2e 'engaged with the screw hole 2d at the other end. Preferably, a non-slip O ring, a washer, etc. are engaged with the threaded rod 2 e '.

Further, a port 6 3 is provided in the center of the lower surface of the grip 6 so as to be screwed into the screw hole 2 d ′ of the small piece 2 c ′.

According to this, if the screw hole in which the screw rod 2 e of the small piece 2 c is screwed into the upper end of the second support rod 2 c is formed, the second support rod 2 c The length can be freely changed by adding small pieces 2 c 'according to the height.

According to this, the second support bar 2c can be moved more smoothly and more smoothly when the second support bar 2c is slid. Industrial use available
