Description

Detailed Description of the Invention 【Technical field】

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cane stake device used by elderly people, disabled people, and injured persons.

[Background technology]

[0002] Conventionally, various canes have been proposed to more stably support the above-mentioned people when they walk or stand using the canes.

For example, in the cane of the prior art 1 (see Patent Document 1), a grounding portion (hereinafter referred to as a supporting member) that contacts the ground is connected to the base of the cane body via a flexible joint. Further, the ground contact portion has a size that can hold the cane body in a vertical state.

With the above structure, when the cane is grounded, the flexible joint is flexibly deformed, whereby the relative angle between the support member and the cane main body can be freely changed. Therefore, by forming the lower surface of the supporting member into a planar shape, the supporting member can be brought into surface contact with the horizontal ground when the cane is lowered. If necessary, an anti-slip is formed on the lower surface of the support member of the cane (see FIG. 3 of Document 1). With the above configuration, the support member can improve the frictional force. , It is possible to maintain stability when it comes into surface contact with the ground.

However, in the above-mentioned cane, for example, as shown in FIG. 10, when the cane (supporting member 23) is grounded on the upper step surface 17 of the stairs, if the pedestrian gives a force to the cane, the flexible joint 13 is bent. Deformed, upper staircase 1
7, the support member 23 is in line contact with the corner portion 20. (In FIG. 10, since the depth is not shown, it is shown in a point contact state.) As a result, when the pedestrian such as the elderly person puts his or her body on the cane in an attempt to step on it, the support member 23 has a corner portion. Since the force is applied to the upper portion 20 from above, the support member 23 easily slips on the corner portion 20. Therefore, a pedestrian has a high risk of rolling over the stairs. That is, as described above, even if the lower surface of the support member 23 is formed in a planar shape, the cane cannot be stably grounded on the ground contact surface including unevenness such as stairs. Becomes

Here, focusing on the movement of a pedestrian such as the injured person walking on a crutch, the lower end of the crutch is grounded in front of the ground, and the crutch is given its own weight with the grounding point on the ground as a fulcrum. Pedestrians shift their weight in an awkward state. In such an operation, the support member is more likely to slip and it is necessary to consider measures.

If the crutch support member is planar,
When the horizontal plane to land on the stairs or the like is narrow, the pedestrian needs to be aware of whether or not half or more of the ground contact portion has landed on the horizontal plane of the stairs. If a pedestrian tries to move his / her weight while the corner portion is in contact with the ground contact portion, the ground contact portion slips as described above, which is dangerous.

By thus forming the grounding portion in a planar shape,
Especially when using on stairs or in narrow ground
On the contrary, it becomes dangerous.

DISCLOSURE OF THE INVENTION [Problems to be Solved by the Invention]

Therefore, the present invention can be used stably by an elderly person, a handicapped person, and an injured person in any place, and in particular, a cane stake that exerts a function on a crutch. The purpose is to provide a device.

[Means for Solving the Problems]

The present invention is a cane stake device comprising a support member for supporting the main body of the cane with a point support portion in point contact with the ground, the support member being capable of flexural deformation. It is connected to the lower end of the cane body through an elastic coupling member, the point support is a plurality of points, and the point supports are arranged on the same virtual plane, and at least from the axis of the cane body. A plurality of the above-mentioned point support parts are arranged at the shifted positions, and the above- mentioned support member is inserted between the point support parts with the convex portion of the ground.
It is a cane stake device set to a size capable of forming a space for slipping in .

The elastic coupling member can be formed of a flexible deformable member such as a rubber member, a coil spring, a leaf spring, or a member formed by integrally incorporating a spring in a rubber member.

The support member may be formed by providing a plurality of point support portions for each support member. In this case, one of the support members can be connected to the cane body portion via the elastic coupling member, and the cane body portion can be supported by a plurality of point support portions. Further, the support member may be formed by including one point support portion for each one support member. In this case, a plurality of the support members can be connected to the cane body portion via the elastic coupling member, and the cane body portion can be supported by the plurality of point support portions.

Further, the support member can be formed by using an elastic member such as a rubber member or a spring. For example,
The entire supporting member or only the point supporting portion of the supporting member may be formed of the elastic member.
In addition, at least one of the plurality of point support portions of the support member may be formed by a suction cup, or may be formed by performing R processing.

Further, a mounting member having a diameter larger than that of the lower portion of the elastic coupling member may be interposed between the supporting member and the elastic coupling member. With the above configuration, in the case where one support member is provided with one point support portion, each support member can be easily displaced from the axis of the main body support portion and attached, which is preferable. .

With respect to the above structure, it is preferable to form a conical closing means for closing the upper space of the mounting member and the elastic coupling member at a portion of the elastic coupling member projecting outwardly from the cane main body.

The closing means may be any means capable of closing the upper space, such as a sheet of vinyl or cloth.

With the above-mentioned structure, the cane can be smoothly carried without being caught in the external environment by the portion protruding in the outer peripheral direction when the cane is used.

When the closing means is attached to the cane at two points in the vertical direction in order to further strengthen the attachment, for example, a member having a bellows shape between the attached two points or an elastic planar member. It is sufficient to use a member formed of a stretchable member such as.

With the above structure, since the elastic coupling member expands and contracts when it is flexibly deformed, the closing means does not stretch, and the function of the stone stake structure of the present invention can be ensured.

The fixing means for attaching the closing means to the wand may be any method such as a snap, a hook-and-loop fastener, a slide fastener, a cord member, a rubber cord member, a button, or a combination thereof. Absent.

Further, the support member may be the elastic coupling member,
Alternatively, the attachment member may be detachably formed, the attachment member may be detachably formed on the elastic coupling member, or the elastic coupling member itself may be detachably formed on the cane main body portion.

The above-described canes include various types of canes such as a crutch, a loftland clutch, an underarm clutch, and a platform cane, in addition to the normally used type.

【The invention's effect】

According to the present invention, by using the elastic coupling member, the elastic coupling member is flexibly deformed according to the shape of the ground contact surface, and substantially all of the point support portions are grounded on the ground to support the walking stick. can do.

Furthermore, by forming a plurality of point supporting portions and forming all the point supporting portions so as to be offset from the axis, a space can be provided between the point supporting portions on the axis. With this, when the elastic coupling member is flexibly deformed, it is possible to allow the convex portion (corner portion) having the uneven shape to enter the space. That is, the flexural deformation in which almost all of the above point support portions try to contact the ground is not hindered.

From the above, pedestrians can use the wand equipped with the above-mentioned stoning device so that the ground contact surface is a horizontal surface even if the ground contact surface includes an inclined surface or unevenness such as stairs. Similarly, they can walk stably.

Further, in the cane stoning device having the above-described structure, even if the point contact is made, in addition to the force for pressing the cane, the pressing force due to the bending stress (moment) acts on the point support portion, so that it is more reliable. The cane body can be supported by the.

Further, at this time, if the whole supporting member is formed of an elastic member, the supporting member itself is also flexibly deformed while being in contact with the ground and bending stress acts, so that the cane main body is more surely supported. can do.

The stabbing device is particularly effective when the cane is a crutch. That is, since the pedestrian moves by applying his / her own weight, the elastic coupling member can be more flexibly deformed, and bending stress can be reasonably applied to the point support portion.

Also, in the movement peculiar to the crutch in which the weight is moved while rotating the ground contact point to the ground as a fulcrum, the elastic coupling member is flexibly deformed in response to the movement, and the pedestrian moves the weight. Easy to peel off. Therefore, it can be said that the stoning device of the present invention including the elastic coupling member is particularly suitable for a crutch.

By using the point support portion at the ground contact portion with the ground, when the walking stick is grounded while walking on the snow road, the support member is inserted into the snow, so that it is stable even on the snow road. The property is improved.

When the support member or the mounting member is detachably formed, it can be replaced when the point support portion is worn. Further, the point support portion can be replaced with a support member formed of a suction cup, if necessary. Further, when the elastic coupling member is detachably formed, it can be replaced when the elastic coupling member is fatigued. Therefore, the stoning device is economical and environmentally friendly.

Further, by forming the above-mentioned closing means, it is possible to prevent the stone ejecting device (particularly the mounting member) from being caught by the external environment such as the corner of the stairs or the fence during walking, and at the same time walking. It does not hinder the operation.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a front view of a crutch 10 in which a canopy device 12 of the present invention is formed at the tip of a cane body 11. FIG. 2 is an enlarged front view (a) showing the stone striking device 12 in FIG. 1 in a partial cross section, and FIG.
It is a bottom view (b) of 2.

As shown in FIGS. 1 and 2, the crutch 10 has a shaft portion 11a formed of a cylindrical metal in the lower portion of the cane body 11. Bolts 11aa project from the lower end of the shaft portion 11a, and the stoning device 12 is attached by screwing by the bolts 11aa. Hereinafter, the structure of the stoning device 12 will be described.

An elastic coupling member 13 having an upper surface having a diameter larger than the diameter of the shaft portion 11a is attached to the lower end portion of the shaft portion 11a. In addition, the elastic coupling member 13
Is the metal members 13a, 13 located on the upper surface and the lower surface.
A rubber member 13c is located between b and is integrally formed in a shape that is inclined in a divergent shape. The elastic coupling member 13
A screw hole 13d is formed in the center of the upper surface of the above, and a bolt 14a projects from the center of the lower surface.

The shaft portion 11a of the elastic coupling member 13
The bolt 11aa protruding downward from the center of the lower end portion of the shaft portion 11a and the screw hole 13d on the upper surface of the elastic coupling member 13 are screwed into and integrated with each other. When the lower surface of the shaft portion 11a and the elastic coupling member 13 are integrally formed more strongly, in addition to screwing as described above, the rubber member 13c and the metal member 13b may be fixed to each other. Good. Also, the elastic coupling member 1
The rubber member 13c in 3 may have a spring built therein to be made more robust.

Further, on the lower surface of the elastic coupling member 13, a mounting member 14 made of a metal and having a disk shape with a diameter of, for example, 85 mm is mounted. The diameter of the attachment member 14 varies depending on the weight of the user and the type of the cane to be attached, but as a guide, the diameter is from 30 mm to 15 mm.
It is formed within a range of about 0 mm depending on the usage form.

The mounting member 14 is formed to have a diameter larger than that of the elastic coupling member 13, and has four through holes in total in four outer peripheral side portions for equally dividing the circumference into four and a disc-shaped central portion. Is formed.

The elastic coupling member 13 and the mounting member 1
4, the bolt 14a protruding from the lower surface of the elastic coupling member 13 is penetrated through the through hole in the central portion of the mounting member 14 and the mounting member 14 is sandwiched by the nut 14b from below. Perform by tightening 14b.

The supporting member 15 for supporting the cane body 11 is a disk-shaped metal piece 15a having an upper portion.
For example, the length and diameter of the lower surface of 5a are 32 mm and 2 respectively.
A 5 mm columnar rubber member 15b is fixedly formed. The length and diameter of the support member 15 also differ depending on the weight of the user and the type of cane worn, but as a guide, the length is 10 mm to 50 mm and the diameter is 10 mm.
To about 40 mm depending on the usage.

Further, a threaded portion of the bolt 15e is formed in the support member 15 so as to protrude from the upper surface of the support member 15. The side surface of the tip of the support member 15 has a tapered shape, and the point support portion 16 that comes into contact with the ground is formed thin.

Further, the four supporting members 15 are inserted into the four through holes formed on the outer peripheral side of the mounting member 14 from the lower side, respectively, and the nuts 15c are tightened from the upper side to mount the supporting member 15. . When the supporting member 15 is mounted on the mounting member 14, the outer peripheral end 14c of the mounting member 14 and the portion 15d located outside the supporting member 15 are mounted so as to be flush with each other. By the way, in the case of the above configuration,
The distance between the centers of the pair of support members 15 located on the diagonal line when attached in this way is 60 mm (as a guideline, it is formed within the range of about 30 to 50 mm according to the usage form). With the above configuration, the crutch 10
The stake device 12 of FIG.

Next, as shown in FIG. 3, when a pedestrian uses the crutch 10 having the above-mentioned configuration to move up the stairs, when the crutch 10 is grounded, among the four support members 15 of the stabbing device 12, Attention is paid to the state where the two support members 15 are located on the upper step surface 17 of the stairs and the remaining two support members 15 are located on the lower step side, and are grounded in such a manner that they straddle the stepped portions (corners) of the stairs.

At this time, when the pedestrian leans on the crutch 10 and presses the crutch 10 (the pressing force is F), first, the two support members 15 are grounded to the upper step surface 17 and the elastic coupling member 13 is first grounded. Deflection and deformation. By flexurally deforming in this way, the lower surface 18 also has a 2
One support member 15 is grounded.

It is assumed that the force F'acts on the point support 16 which is in contact with the upper surface 17.

Here, due to the above-mentioned flexural deformation, bending stress M (F '× L1) acts on each point support portion 16 of the two support members 15 grounded on the upper surface 17. The respective point support portions 16 corresponding to the amount of the bending stress M acting.
Can press the upper surface 17 more strongly.

That is, the elastic coupling member 13 can be used, and a distance (L1) displaced from the center of gravity 21 of the crutch 10 can be secured and the crutch 10 can be supported by the two point support portions 16. Therefore, regardless of whether the point support portion 16 is grounded on the front side (near the corner portion 20) of the upper step surface 17 or at the back side of the corner portion 20, it is possible to obtain an approximately constant pressing force due to bending stress. .

Even when the point support portion 16 is grounded further on the upper surface 17 than the corner portion 20, the space between the support members 15, that is, the bottom of the mounting member 14. The corner portion 20 enters the space on the side, and the corner portion 2
Since 0 does not come into contact with the stone striking device 12, the elastic coupling member 13 can be flexibly deformed until all the point supports 16 come into contact with the ground.

By the way, as shown in FIG. 10, the supporting member 2
When the lower surface of 3 is formed in a planar shape, it is flexurally deformed as described above, but the upper step surface 17 is supported by the corner portion 20 in point contact, and the corner portion 20 is pressed against the point support portion 16. Bending stress acts.

In this case, the distance (L2) between the barycentric axis 21 of the crutch 10 and the corner portion 20 becomes shorter than the above L1, so that the pedestrian has the same force (F) as described above. ), The bending stress M ′ (F ′ × L2) becomes smaller than that in the above case. Note that, for example, if the support member 15 is grounded in a state where the center-of-gravity axis 21 is close to the corner 20, the distance (L2) between the center-of-gravity axis 21 of the crutch 10 and the corner 20 is further reduced, so that Bending stress does not work.

Further, when the stepped portion 19 of the staircase is large as shown in FIG. 4 (a), the pedestrian grounds the crutch 10 at a position on the ground contact surface 24 where the center axis 21 of the crutch 10 is displaced from the ground contact surface. Attention is paid to the state of floating in the air. It should be noted that in FIG. 4, the structure is simplified for the sake of easy viewing.

When a pedestrian leans on the crutch 10 in the above state, the elastic coupling member 13 is flexibly deformed, but the crutch 10 provided with the stoning device 12 as shown in FIG. Similarly, the ground contact surface 2 of the support member 15
A strong bending stress acts on the point grounding portion 16 that is in contact with the contact point 4 to reliably support it.

Moreover, the point support portion 16 can maintain a grounded state on a horizontal grounding surface, and can be stably supported without slipping even when a force is applied.

On the other hand, the supporting member 2 of the stoning device 22
When the lower surface of 3 is formed in a planar shape, and the pedestrian leans on the crutch 10 as shown in FIG.
Since the gravity center axis 21 is displaced from the ground plane 24, when the elastic coupling member 13 is flexibly deformed, the supporting member 23 slides and slides down as shown in FIG. 4D, which is dangerous. Even if the support member 15 is formed of an elastic member such as rubber, if the pedestrian leans on the crutch 10, the support member 23 cannot support the pedestrian and the support member 23 is bent and deformed. It is dangerous because it will slip off. Here, as shown in FIG. 4B, the crutch 10
Attention is paid to the support member 15 when the user is leaning on his body. Since the support member 15 is formed almost entirely of a rubber member, the support member 15 (particularly the point support portion 16) is compressed and contracted, so that the support member 15 comes into closer contact with the ground contact surface 24. Moreover, since the bending stress generated by the supporting member 15 itself being flexurally deformed can be applied to the point supporting portion 16, the bending stress can be further pressed against the ground contact surface 24.

In addition to the above stairs, the stoning device 30 can be said to be a suitable use environment even if it is an inclined ground 37 or an uneven ground 38 as shown in FIG. Note that, in FIG. 5, as in FIG. 4, the structure is simplified for the sake of easy viewing.

That is, in FIGS. 5A and 5B,
When a pedestrian touches the cane, the arbitrary point support 16 first touches the ground 37, 38, but the cane is unstable when supported by only one point support. However, when the pedestrian further puts his / her body on the walking stick, the elastic coupling member 13 is flexibly deformed, so that substantially all the point support portions 16 can be grounded to the ground surfaces 37 and 38.

Further, focusing attention on the case of FIG. 5B, the stone ejecting device 12 is constructed so that it is grounded to the ground 38 by the plurality of point supporting portions 16,
Even if the elastic coupling member 13 bends and deforms, each support member 15
In the space 39 between them, that is, the space 39 below the mounting member 14, the convex portion 38a of the uneven ground enters, and the convex portion 38a does not directly contact the support member 15, the mounting member 14, and the like. Therefore, substantially all the point support parts 16 can be grounded.

By the way, as shown in FIGS. 5 (c) and 5 (d), in the case of a cane formed by using the stone projecting device 30 for supporting a plurality of points without using the elastic coupling member 13, the ground 3 is used.
If you touch the ground at 7, 38, basically the ground 37, 38
The cane (pedestrian) will be supported only at one point in contact with. In this case, it is a single point support and the point support part 16
Is unstable because it deviates from the axis 21 of the center of gravity, and slips particularly well when the grounds 37, 38 are wet, which is dangerous.

Further, in this case, in order to support the walking stick at a plurality of points, it is necessary for the pedestrian to tilt the walking stick according to the shapes of the ground contact surfaces 37 and 38. In particular, in FIG. 5 (d), it is necessary to tilt the cane frequently on the ground 38 having a severe uneven shape, and the function of the cane is not fulfilled.

Further, as shown in FIGS. 5 (e) and 5 (f), when the elastic coupling member 13 is used and the support member 23 is formed in a planar shape, as shown in FIG. 5 (e), In the inclined surface 37, the elastic coupling member 13 is flexibly deformed according to the inclination angle of the inclined surface 37, and the supporting member 2
The whole 3 can be grounded on the ground 37 to support the cane.
However, as shown in FIG. 5 (f), when the cane is grounded on the ground 28 having the uneven shape, the staff tries to deform flexibly, but the uneven shape cannot be surface-supported and cannot be stably grounded. , There is a risk of slipping.

As described above, by using the wand equipped with the stoning device 30, even if the ground contact surface is the inclined surface 37 or the ground surface 38 having the above-mentioned uneven shape, the pedestrian can perform the same operation as in the case of a horizontal surface. You can walk stably.

Further, the support member 15 may be constructed as shown in FIG. That is, as shown in FIG. 6A, if the point support portion 32 of the support member 31 is formed by a suction cup, it is effective when the ground contact surface 24 gets wet and slips easily. Further, in the case of FIG. 6B, if the point support portion 34 of the support member 33 is formed in a curved shape, when the pedestrian moves his / her weight, the crutch 10 is tilted with respect to the ground contact surface 24 to contact the ground. Even then, it is possible to move stably with the point support portion 34 as a fulcrum.

The stone-equipped device 12 includes the point support portion 1
6 on the axis 21 of the shaft portion 11a of the crutch 10
However, in addition to them, the support member 15 (point support portion 16) may be formed on the axial line 21 of the crutch 10.

With the above construction, when the elastic coupling member 13 is extremely flexed and deformed, the central portion of the mounting member 14 does not directly contact the corner portion 20, and the support member 15 (point support portion 16) is provided. Can be supported by.

Further, as another embodiment, the stoning device 12 may be formed by directly attaching the support member 15 to the lower portion of the elastic coupling member 13 without using the attachment member 14. For example, as shown in FIG. 6C, one support member 35, such as four point support portions 36 (only two on the front side are shown in the figure) for each support member 35 is configured.
On the other hand, a plurality of point support portions 36 can be configured to form the stone striking device 12.

Although the description has been given here by taking the case where the pedestrian moves using the crutch 10 as an example, the crutch 1
In the case of 0, the pedestrian can give the elastic coupling member 13 a force enough to cause the pedestrian to flex and deform, without consciously giving the force, only by gaining his / her weight.

Therefore, a large bending stress can be easily generated and the pedestrian can be surely supported. That is,
The stabbing device 12 of the present invention, as shown in FIG.
Although not limited to 0, any cane 60 can be used, but a crutch 10 or a cane of a type such as the loftland clutch 70 shown in FIG. Can be said.

For example, the stone striking device 12 may be used with the crutch 10
Attention will be paid to the case where the elastic coupling member is mounted on the base plate and has a large elastic coefficient. In this case, the pedestrian grounds the lower end of the crutch 10 to the front ground, and the pedestrian rotates the crutch 10 to move the weight with the grounded point as a fulcrum.

In this operation, a restoring force for trying to make the crutch 10 stand upright acts on the elastically deformed elastically deformable member. That is, the restoring force facilitates the pedestrian to move his / her weight forward.

Also, this time, when the pedestrian lands on his / her body after shifting his / her weight, the elastic coupling member, which has been flexibly deformed in the same manner as described above, is acted on by the restoring force that makes the crutch 10 stand upright. That is, since the restoring force acts in a direction that buffers the landing motion, even if the pedestrian is an injured person, the landing can be performed stably. Also from the above, the stoning device 1
It can be said that 2 is particularly suitable for use in the crutch 10.

Next, as another embodiment, FIG.
As shown in (b), conical closing cloth members 71 and 75 may be formed to close the upper space of the portion projecting in the outer peripheral direction from the cane main body 11. The closure cloth member 71 in FIG. 9A has a trapezoidal shape when expanded,
A string member 72 is attached along the upper end of the trapezoidal shape. The string member 72 projects in a flap shape only on one side at the upper end portion of the closing cloth member 71.

One snap 73a is attached to one surface of the tip of the string member 72, and the other snap 73b is opposite to the surface on the opposite side of the upper end portion of the closing cloth member to which the one snap 73a is attached. Attached to the side surface.

To attach the closing cloth member 71 to the crutch 10, the string member 72 of the closing cloth member 71 is attached to the crutch 10.
The shaft 11a is wound around the outer peripheral portion in the lower part. In addition, the pedestrian may use the pair of snaps 73a, 7a.
It can be attached by locking 3b. As described above, it is possible to surround the elastic coupling member 13 so that the shaft portion 11a has a side surface shape that widens in the outer peripheral direction as it descends from the upper side portion of the elastic coupling member 13.

That is, with the above configuration, when the crutch 10 is moved to the next ground contact point while walking, the attachment member 14 is not caught on the iron fence, stone, or the like. Moreover, even if the elastic coupling member 13 is flexed and deformed, the closing cloth member 71 is formed.
The lower end of is a free end. Therefore, the walking motion is not hindered by the closing cloth member.

As shown in FIG. 9 (b), the closing cloth member 75 has the string member 7 at the lower end as well as at the upper end.
6, and snaps 77a, 77b may be attached, and both upper and lower ends may be locked by the snaps 77a, 77b.

Further, when the closing cloth member 75 is attached to the cane main body portion 11 (shaft portion 11a), the closing cloth member 75 expands and contracts vertically in the vertical central portion on the outer peripheral surface corresponding to the side surface. A predetermined number of bellows expansion / contraction portions 78 are formed.

With the above structure, the corners of the stairs,
It is possible to prevent the attachment member 14 from being reliably hooked without rolling up or separating when the closing cloth member 75 comes into contact with an iron fence, a stone, or the like. Moreover, since the bellows expanding / contracting portion 78 of the closing cloth member 75 contracts, the closing cloth member 75 does not hinder the walking motion.

In addition, the closing cloth member 75 may be formed in a planar shape with an elastic material such as rubber. Accordingly, even when the upper and lower ends are fixed without forming the bellows expansion / contraction part 78, the closing cloth member 75 can be expanded / contracted.

In the crutch 10 equipped with the stoning device 12 on the horizontal ground, the point support portions 16 are arranged on the same virtual plane and are supported by the point support portions 16. , It can stand upright on a level ground without any support. As a result, even if it is brought into a small store or the like, there is an effect that it is not an obstacle.

For a pair of canes such as the crutch 10, a cord for connecting the two canes, a belt, a locking means such as a snap is provided to ensure that the two canes are secured. Can stand upright together.

In the correspondence between the above-described embodiment and the configuration of the present invention, the closing cloth members 71 and 75 of this embodiment are
Although corresponding to the closing means of the present invention, the present invention is not limited to the configuration of the above-described embodiment, and many embodiments can be obtained.
