[Technical field to which the invention belongs]

 The present invention relates to a strap for a walking assistance pole.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, walking assistance poles have been used for trekking, hiking, etc., not only for elderly persons and other persons with physical disabilities but also for healthy persons. In recent years, telescopic walking assistance poles that can be extended to a predetermined length when used and can be shortened when carried are widely used.

After the shaft 3 is extended, the walking assist pole is fixed to the lower end of the shaft 3 while holding the grip 5 fixed to the upper end of the shaft 3 with the hand 7 as shown in FIG. It is designed to assist walking by hitting the ground appropriately with a stone foot (not shown).

In order to prevent the walking assist pole 9 from falling even if the hand 7 releases the grip 5 for gripping, the loop 14f of the strap 12 attached to the upper part of the shaft 3 is hung on the wrist 7a. I'm using The strap 12 is formed by attaching a loop-shaped hanging string 14 having a fixed length to the upper end of the shaft 3 via a ring member 16 so as to be inseparable therefrom, as shown in the figure.

[0005]

[Problems to be solved by the invention]

 However, with the strap 14 irremovably fixed to the shaft 3 as described above, even if the hand 7 is immediately released from the grip 5 when the walking assistance pole 9 is caught on something, the strap 14 on the wrist 7a Therefore, since the user is connected to the walking assistance pole 9, the user may be pulled by the pole 9 and get into an unexpected trouble, which is inferior in safety.

In addition, since the size of the loop 14 f of the hanging string 14 cannot be adjusted, it is possible to achieve both the detachability of the hanging string 14 to the hand 7 and the holding property of the walking assist pole 9 to the hand 7. Can not. That is, if the loop 14f is small, it is difficult to insert and remove the hand 7 into it, that is, the detachability is poor. Conversely, if the loop 14f is large, the hand 7 easily comes off from the loop 14f, and the walking assist pole 9 is easily dropped, that is, Poor holding property of the pole 9 is poor.

The present invention has been made in view of such circumstances, and a purpose of the present invention is to provide a walking assistance pole that is excellent in holding properties of a walking assistance pole and detachability to a hand, and has high safety. To provide a strap.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, a device according to claim 1 includes an elastic cylindrical body fitted on the outer periphery of a shaft, a slit formed in a part of a cylindrical wall of the cylindrical body along an axial direction of the cylindrical body, It is characterized by comprising a hanging string attaching portion integrally formed on the outer periphery of the cylindrical body in the vicinity of the slit, and a loop-shaped hanging string fixed to the hanging string attaching portion.

According to the invention, even if the hand releases the grip when the walking assistance pole is caught on something, the hand is connected to the walking assistance pole by the strap and the hand is pulled. However, at this time, the elastic tubular body of the strap is pulled on the tubular wall by the shaft of the walking assistance pole, and the hanging strap attaching portion is pulled by the hanging strap hung on the hand. It bends due to elastic bending deformation that increases the radius of curvature. Then, the shaft can be prevented from coming off from the slit that has been expanded by an appropriate amount due to the deformation, that is, the shaft comes off from the strap and the hand can be detached from the walking assistance pole, and it can be prevented from getting caught in unexpected trouble.

[0010] Since the suspension string attaching portion is formed close to the slit, a cylindrical wall exists instead of the slit on the opposite surface of the suspension string attaching portion on which one pulling force acts. The shaft does not come off the cylinder until the cylinder wall is bent and deformed by the other pulling force received from the shaft and the slit is expanded to some extent. For this reason, an appropriate separation resistance can be reliably provided, and separation can be prevented with an extremely small pulling force.

According to a second aspect of the present invention, there is provided the walking assist pole strap according to the first aspect, wherein the suspension string attaching portion extends 90 to 150 degrees from the center of the slit along the outer periphery of the cylindrical body. It is characterized by being formed in a range.

[0012] According to the invention, the hanging string attaching portion is formed in a range of 90 to 150 degrees from the center of the slit along the outer periphery of the cylindrical body, so that the detachment resistance can be reliably provided. In addition, by appropriately changing the attachment portion within the above-described angle, the detachment resistance can be easily changed, and various types of applications such as physical strength and purpose of the walking assistance pole user can be achieved. A strap with detachability can be provided.

According to a third aspect of the present invention, in the strap for a walking assistance pole according to any one of the first and second aspects, the hanging string is bundled with the hanging string to reduce the size of the loop. A loop expanding / contracting means for expanding / contracting is provided slidably, and a stopper for preventing the loop expanding / contracting means from falling off the hanging string is provided at the loop end to engage with the loop expanding / contracting means. It is characterized by the following.

[0014] According to the invention, the size of the loop of the hanging string can be adjusted by the loop expanding / contracting means. When fixing the wrist, the loop hung on the wrist can be reduced and fixed. Therefore, the strap can be easily attached to and detached from the hand, and it can be securely fixed to the wrist, so that the walking support pole can be easily held in the hand. In addition, since the loop end of the hanging string is provided with a retaining means, when the loop expanding means slides on the hanging string, it engages with the loop expanding means to prevent it from falling off the hanging string. It can be reliably prevented.

[0015]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail. FIG. 1 is a perspective view showing a state in which a strap according to an embodiment of the present invention is attached to a walking assistance pole, FIG. 2 is a perspective view showing a state in which the strap is hung on a wrist, and FIG. It is a top view and a side view.

As shown in FIG. 1, the strap 11 of the walking assistance pole of the present embodiment is used for the walking assistance pole 9 in which the shaft 3 is formed of a cylindrical pipe, and is attached to the shaft 3 below the grip 5 thereof. The strap 11 is attached.

The strap 11 basically includes a cylindrical body 13 fitted coaxially with the outer periphery of the shaft 3, and a loop-shaped hanging string fixed to a hanging string attaching portion 13 a of the cylindrical body 13. The loop 15f is hung on the wrist to connect the walking assistance pole 9 with a hand (not shown).

The cylindrical body 13 is made of resin as a material having elasticity, the inner diameter thereof is set slightly smaller than the outer diameter of the shaft 3, and is fitted to the shaft 3 with a slight gripping force. For this reason, the shaft 3 can be slid in the axial direction, and can be temporarily fixed at an arbitrary position in the axial direction of the shaft 3 by the frictional force of the gripping force. In addition, as the resin, a nylon resin, a polyacetal resin, a polyamide resin, an ABS resin, and the like are preferable.

The cylindrical wall 13b has a slit 13c formed in a straight line along the axial direction. As shown in FIG. The hanging string attaching portion 13a is integrally formed at the position of the degree so as to protrude outward in the cylinder radial direction. Then, as shown in FIG. 1, when a pulling force in the cylinder radial direction acts so that the hanging string attaching portion 13a and the shaft 3 are separated from each other, the cylindrical wall 13b is elastically bent such that its radius of curvature becomes large. Due to the deformation, the slit 13c expands, and the shaft 3 comes off from the slit 13c.

Since the suspending string attaching portion 13a is formed at a position 90 degrees with respect to the slit 13c, the opposite surface of the suspending string attaching portion 13a on which one of the pulling forces acts is not a slit 13c but a cylinder. There is a wall 13b. The shaft 3 does not come off the cylindrical body 13 until the cylindrical wall 13b is bent and deformed by the other pulling force received from the shaft 3 and the slit 13c is expanded to some extent. For this reason, an appropriate resistance can be surely given when this comes off, and it can be prevented from coming off with an extremely small pulling force.

A through hole 13d in the direction of the cylinder axis is formed substantially in the center of the plane of the hanging string attaching portion 13a, and a metallic circular ring 17 is inserted into and attached to the through hole 13d. The hanging string 14 is engaged with the ring 17.

The suspension string 14 is formed by folding a single string body 15 made of a synthetic fiber, and connecting and connecting both ends of the string body 15 by welding or stitching to form a loop. The connecting portion 15b is located at a position slightly shifted from the loop end 15c, which is one of the folded portions, and is covered and bound by the connecting portion protecting metal fitting 19 together with the string portion overlapping the connecting portion 15b. Then, the ring 17 is inserted into a small loop 15 e formed between the joint protection metal 19 and the loop end 15 c, and the cylindrical body 13 and the hanging string 14 are connected via the ring 17. Have been.

The hanging string 14 is slidably passed through a through-hole 21 c formed in the center of the spherical member 21 in a state where the string body 15 is folded in a folded state, and Are formed. The size of the loop 15f can be adjusted by moving the spherical member 21 along the cord body 15.

As shown in FIG. 3, one end 21a of the through-hole ends 21a and 21b has a diameter larger than the string width W, and the other 21b has a smaller diameter than the string width W. For this reason, sliding resistance is given to the small-diameter through-hole end 21b, and the spherical member 21 can be fixed at an arbitrary position of the cord body 15.

A ring member 23 is provided at the other loop end 15 g of the cord body 15 as a retaining means for preventing the spherical member 21 from falling off from the loop end 15 g. In this ring member 23, the cord body 15 is inserted through a central through hole 23a, and the outer diameter of the ring member 23 is larger than the small diameter side through hole end 21b of the spherical member 21. The engagement of these prevents the spherical member 21 from coming off.

A use situation of the walking assist pole strap 11 of the present embodiment having the above configuration will be described with reference to FIGS. 1 and 2. FIG.

As shown in FIG. 1, the cylindrical body 13 of the strap is fitted to the shaft 3 below the grip 5 of the walking assistance pole 9. Then, the cylindrical body 13 is slid and moved in the axial direction of the shaft 3 to adjust its position, and is positioned at, for example, the upper end of the shaft 3.

Next, the shaft 3 is extended from a contracted state when the portable device is carried to an easy-to-use length to have a cane shape. Then, the spherical member 21 is moved to the ring member 23 side of the cord body 15 to enlarge the loop 15f of the cord body 15 so that the hand can be easily passed through, and the hand is passed through the loop 15f as shown in FIG. Then, with the loop 15f hung on the wrist 7a, the spherical member 21 is slid in the opposite direction to reduce the loop 15f to make it difficult for the hand 7 to come off the hanging string 14. Then, as shown in the drawing, the walking assist pole 9 assists the walking while holding the grip 5 for gripping with the hand 7 and hitting the ground appropriately with a stone foot, thereby enjoying trekking and hiking. In order to remove the strap 11 from the wrist 7a, it is clear that the operation described above should be performed in the reverse direction, and the description thereof will be omitted.

Further, even if the grip 5 is suddenly released during walking, the walking assist pole 9 is securely held on the hand 7 by the hanging string 14 whose loop 15 f has been reduced and adjusted to fit the wrist 7 a. Therefore, it is possible to prevent the walking assistance pole 9 from being dropped and lost.

Further, when the walking assist pole 9 is caught on something and the hand 7 is pulled by the strap 11 hung on the wrist 7 a, the cylindrical body 13 of the strap 11 becomes the shaft of the walking assist pole 9. By pulling the cylindrical wall 13b by 3 and the hanging string attaching portion 13a by the hanging string 14 hung on the hand 7, the cylindrical body 13 bends by elastic bending deformation whose radius of curvature becomes large. Then, the shaft 3 comes off from the slit 13c which has been expanded by an appropriate amount due to the deformation, that is, the shaft 3 comes off from the strap 11, and the hand 7 is detached from the walking assistance pole 9, so that the hand 7 is pulled excessively. This avoids stress and prevents you from getting into trouble.

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments, and various modifications can be made without departing from the gist of the present invention.

(A) In the present embodiment, the hanging string attaching portion is formed at a position 90 degrees from the center of the slit. However, the present invention is not limited to this, and the hanging string attaching portion is formed at 90 to 150 degrees depending on the physical strength of the user. The formation position may be changed within the range. For example, for people and children with weak wrists, it is formed at a position of 150 degrees where the resistance when the strap comes off is reduced so that the cylinder of the strap comes off from the shaft before a large pulling force acts on the wrist, Conversely, for people with strong wrists, the walking assist pole may be formed at a 90-degree position where it is difficult to come off in order to avoid the loss of the walking assist pole caused by the easy removal of the walking assist pole.

(B) In the present embodiment, since the shaft of the walking assistance pole has a cylindrical pipe shape, a cylindrical body is used as the cylindrical body of the strap, but the outer shape of the strap is fitted to the shaft. Needless to say, an appropriate cylinder is appropriately used. For example, when the shaft is an elliptical pipe, an elliptical cylinder is used. When the shaft is a square pipe, a quadrilateral cylinder is used.

(C) In the present embodiment, the inner diameter of the cylindrical body is made smaller than the outer diameter of the shaft so as to be fitted with a slight gripping force. However, the present invention is not limited to this. The shaft may be larger than the outer diameter so that no gripping force is generated. However, in this case, the cylinder slides freely in the axial direction of the shaft, making it difficult to use the strap. For this reason, it is desirable to provide an engagement annular convex portion on the shaft that engages with this cylindrical body and regulates the sliding range thereof.
