  The strap 6 attached between the upper strap support member 9 and the lower strap support member 10 of the main body portion 7 thus configured is formed of a cloth having a predetermined width as shown in FIGS. The strap main body 6a has a pair of locking bands 6b and 6c at least one end of which is connected and fixed to both ends in the longitudinal direction (upper and lower) of the strap main body 6a by sewing or the like. Then, the upper locking band 6b has its distal end locked to the locking hole 9d of one wing portion 9b of the upper strap support member 9 and turned back, and the distal end portion is fixed together with the base end portion to the strap body portion 6a. Thus, the length with respect to the grip body 5 is set to a predetermined value, and is attached to the grip body 5 in a non-detachable manner.

  On the other hand, the lower locking band 6c is disposed on the back surface of the lower end of the strap 6 while adjusting the length of the strap 6 by inserting the tip of the lower strap 6c into the locking hole 10c of the locking portion 10b of the lower strap support member 10 and turning it back. The cloth fastener (not shown) is engaged with the cloth fastener (not shown) disposed on the surface of the strap body 6a. Thereby, the strap 6 is attached between the one wing portion 9b of the upper strap support member 9 of the grip body 5 and the locking portion 10b of the lower strap support member 10 with a predetermined length. . The position of the strap 6 with respect to the grip body 5 is adjusted by adjusting the length of the lower locking band 6c.

  Next, a method for using the grip 1 will be described. First, the grip body 5 is fitted into the upper end of the pole 3 by using the elasticity of the body portion 7 itself of the grip body 5 or an adhesive in the mounting center 11 at the manufacturing company. It is attached to the upper end of the pole 3 and shipped. At the time of manufacture and shipment, the wing portion 9b of the upper strap support member 9 can be rotated by a predetermined angle at the left and right and front and rear symmetrical positions, and the lower strap support member 10 can be rotated 360 degrees around the axis. Therefore, in the strap 6 in which the upper locking band 6b is locked in the locking hole 9d of one wing portion 9b of the upper strap support member 9, the lower locking band 6c is engaged with the lower strap support member 10. Lock to the stop hole 10c.

  As a result, the walking assist pole 2 whose upper end of the strap 6 is locked to the locking hole 9d of one wing portion 9b of the upper strap support member 9 is used for the left hand, and the locking hole 9d of the other wing portion 9b is set to the locking hole 9d. The walking support pole 2 with the upper end of the strap 6 locked is shipped for the right hand, that is, when the walking support pole 2 is manufactured and shipped, the upper strap support member 9 is used for both the left and right walking assistance poles 2 ( Shared).

  When the pedestrian holds the two walking assistance poles 2 with his left and right hands and performs a Nordic walk, the walking assistance pole 2 corresponding to each hand is used with the index finger, middle finger, ring finger and little finger of each hand. The inner surface of the strap 6 is lightly in contact with the back of each hand by adjusting the length of the locking band 6c below the strap 6 and holding the body portion 7 of the grip body 5 with each finger. To. The length adjustment of the strap 6 is performed for each walking assistance pole 2 for the left hand and the right hand.

  In the state where the body portion 7 of the grip body 5 is gripped by four fingers and the thumb is placed on the thumb placement surface 8a of the thumb support portion 8, the back of each hand is supported by the strap 6 and the index finger is located above the index finger. And the like are regulated by the wing portion 9b of the upper strap support member 9, and each hand is stably supported. Further, since the upper strap support member 9 and the lower strap support member 10 are arranged so as to be rotatable by a predetermined angle in the direction around the axis, the degree of freedom of the positional relationship of the strap 6 with respect to the grip body 5 is increased. It is possible to reliably follow the positional change of the hand relative to the grip body 5 at the time, and to walk while maintaining a good holding feeling of the grip body 5 by each hand.

  That is, in the case of the grip 1, the upper strap support member 9 and the lower strap support member 10 that support the upper end and the lower end of the strap 6 can be rotated by a predetermined angle with respect to the main body portion 7, thereby The degree of freedom of the positional relationship with respect to the grip body 5 is greatly improved.

  As described above, according to the grip 1, the upper end of the strap 6 is disposed at the upper end portion of the main body portion 7 of the grip body 5 so as to be rotatable by a predetermined angle, and has an upper portion having a pair of wing portions 9 b at the left and right and front and rear symmetrical positions. Since the upper strap support member 9 is attached to the strap support member 9, the upper end of the strap 6 is rotated by the pivoting operation of the upper strap support member 9, so that the positional relationship between the upper end of the strap 6 and the grip body 5 can be given freedom. Thus, it is possible to sufficiently enhance the walking assist effect, such as improving the hold feeling during walking.

  Further, the upper strap support member 9 is rotatably attached between the main body portion 7 and the thumb support portion 8 of the grip body 5, and the wings are integrally formed symmetrically on the left and right sides of the attachment portion 9a. Since the portion 9b is provided, even when the strap support member 9 rotates, the symmetrical positional relationship of the wing portion 9b can be maintained and the index finger can be reliably supported, and the upper strap support member 9 itself can be easily and inexpensively formed by integral molding. Can be formed. Further, since the fitting hole 9c provided at the center position of the attachment portion 9a of the upper strap support member 9 is rotatably fitted to the fitting convex portion 8c formed on the lower surface of the thumb support portion 8, the upper strap support is supported. The rotation mechanism of the member 9 can be simplified, and the rotation operation can be performed reliably and stably.

  Further, since the upper strap support member 9 is formed in a left-right and front-back symmetrical shape, it can be used for both the left-hand and right-hand walking assist poles 2, and the members can be made common and the cost of the grip 1 can be reduced. For example, it is possible to obtain a grip 1 that is advantageous in terms of cost, for example, replacement work of the grip 1 that is worn or the like can be easily performed.

  Further, since the lower strap support member 10 to which the lower end of the strap 6 is connected and supported is attached to the lower end portion of the grip body 5 so as to be able to rotate 360 degrees in the direction around the axis, the strap 6 is rotated by the rotation of the lower end of the strap 6. The positional relationship between the lower end of the grip and the grip body 5 can be given a degree of freedom, and together with the degree of freedom due to the rotation of the upper strap support member 9, a predetermined degree of freedom can be secured to the strap 6, and The walking assist effect can be further enhanced, for example, a good hold feeling can be obtained in the grip 1.

  In particular, since the lower strap support member 10 is attached to the lower end portion of the main body portion 7 of the grip body 5 so as to be rotatable about the 360-degree axis, the lower strap support member 10 rotates with respect to the grip body 5. Thus, the lower end of the strap 6 can be easily set to the right and left optimum positions of the grip body 5, and the walking assist effect can be further enhanced.

  In addition, in the said embodiment, although the one latching | locking part 10b was provided in the lower strap support member 10, this invention is not limited to this structure, For example, a latching part is located in the opposing position of the diameter direction of the fitting part 10a. 10b may be provided. If comprised in this way, the rotation range (angle) of the lower strap support member 10 is made into a predetermined angle (for example, about 20 degrees) instead of 360 degrees like the upper strap support member 9, and the lower strap support member 10 Inadvertent rotation can be regulated.

  Moreover, in the said embodiment, although the upper strap support member 9 enabled it to rotate continuously to the fitting convex part 8c of the thumb support part 8, for example, the inner peripheral surface and fitting convex part of the fitting hole 9c It is good also as a structure which the upper strap support member 9 rotates in steps by forming the protruding item | line of an up-down direction in the outer peripheral surface of 8c. In this case, it is preferable that the upper strap support member 9 can be rotated only when a predetermined force acts in the direction around the axis by setting the locking strength by the ridges to a predetermined value. Furthermore, in the above-described embodiment, the lower strap support member 10 can be rotated 360 degrees. However, for example, the lower strap support member 10 is fixedly provided on one side surface of the main body 7 as in the prior art. There may be.

  In addition, the shape of each part of the grip body 5, the configuration of the strap 6, the configurations of the upper strap support member 9 and the lower strap support member 10, etc. in the above embodiment are merely examples. The locking bands 6b and 6c can be used together, and the position of the strap 6 and the body portion 7 can be set according to the shape of the hand, or the strap 6 itself can be detached from the grip body 5 for replacement.
