[Technical Field]

[0001]

The invention relates to a training belt and a rubber ball

member which comprises a stretchable belt made of, for example,

rubber and the like and a rubber ball member for using various

trainings, forexample, exercise, beauty, health suchasimproving

low back pain, rehabilitation of such as gait disorder, solving

lack of physical activity, limbs, legs and waist, prevention of

cognizance syndrome, sports training by strengthening back

muscles, chest muscles, bodybuilding, etc. and various training

in other fieldslike sports training (hereinafter, simply referred

to as "training").

[Background]

[0002]

In conventional, as a training tool using such various

training, for instance, an exercise rubber band, a loop band, and

a training tube, etc. are used.

[0003]

As such a training tools, conventionally, as for so-called

"expander", a ring shape (loop shape) loop band, which uses, for

instance, the stretchablememberhavingflexibilitymade ofrubber etc., is used.

[0004]

In such a loop band, the length of the loop band is constant.

Therefore, in accordance with, for instance, using object,

using portion, training method, training strength, and strength

of loop (load), the loop band of various lengths should be

prepared.

As a result, the cost is increasing and it is complex and

troublesome since it is necessary to select a loop band and train

with the selected loop band.

[0005]

Therefore, in Patent Document 1 (JP 2017-18243, A), the

training tool, which can be used as the loop band having the

arbitrary length without necessity of preparing the loop band

having various lengths, is disclosed.

[0006]

That is, Fig. 20 is a perspective view of the training tool

shown in Patent Document 1.

[0007]

As shown in Fig. 20, the training tool 100 shown in Patent

Document 1, a plurality of the loop 106 comprising the first

stretchable member102 and the second stretchable member104 which

is longitudinally longer than the first stretchable member 102,

are mutually connected through the joint portion 108.

[0008]

In addition, for instance, right and left hand are inserted

into the loop 106 and the holding part (position) is variously

changed.

As a result, the length of the training tool 100 is changed

so that the strength of the load applied during training can be

adjusted.

[Prior Art Reference]

[Patent Document]

[0009]

JP, 2017-18243, A

[0010]

However, in the training tool 100 described in Patent

Document 1, a plurality of the loop 106 comprising the first

stretchable member102 and the second stretchable member104 which

is longitudinally longer than the first stretchable member 102,

should be mutually connected through the joint portion 108.

As a result, the component is complicated, and the cost is

increasing.

[0011]

Moreover, it is impossible to use the conventionalloop band

which is sold generally.

For the person who trains, burden is forced economically

and moreover, the burden of carrying etc. is forced.

[0012]

In addition, in the training tool 100 described in Patent

Document1, forinstance, according to the holdingpart (position)

in which the right and the left hand are inserted into the loop

106, the portion that remains in the both ends portion is caused.

As a result, the problem might be caused by becoming

obstructive for training and getting twisted to the surrounding

and other parts of the body.

[0013]

Moreover, when a conventional loop band is used to train,

such as the exercise of the foot and the exercise of the knee,

both feet should be put into the loop while sitting on a chair

or bending state.

Therefore, it is inconvenient and a large space to some

extent is required.

[0014]

Therefore, it is unsuitable for training, for instance,

training at the time of work and study, etc. sitting on a

chair,

training while watching television and video, etc., sitting

on a chair of home and sitting on a sofa,

training when moving in passenger's seat and back seat of

car and training when moving in charabanc, airplane, ships and

vessels and train, and training on bedding and bed.

[0015a]

It is desired to address or ameliorate one or more

disadvantages or limitations associated with the prior art, or

to at least provide a useful alternative.

first the engaging member 20, a confirmation portion22a, in which

the both sides can be confirmed, is formed.

In this Embodiment, a mark of the umbrella is formed as the

confirmation portion 22a.

[0143]

By composed like this, for instance, by adhering the sealing

and by forming the confirmation portion 22a comprising indication

suchas braille, mark andclassifications andconvexoconcave, etc.,

to the surface of the buckle type engaging member 22 of the first

engaging member 20, the both sides can be confirmed and it can

be prevented fromprovidingbymakingamistake ofthe confirmation

of the both sides.

[0144]

In addition, instead of providing the first protruded

engaging portions 30a, 30b, and the second protruded engaging

portions 32a, and 32b like this, as shown in Fig. 14, it is also possible that the structure in which only a protruded engaging portion 28a is provided to the edge of the buckle opening and closing member 28.

[0145]

On the other hand, a second engaging member 38, which is

detachably coupled to the other edge of the belt member 12 (i.e.

the other edge 12d of the second belt member 12b) that is coupled

by the intermediate engaging member 14, is provided.

[0146]

As shown in Fig. 1-Fig. 4, in this Embodiment, the second

engaging member 38 is not especially limited that it is able to

use conventional well-known buckle type engagingmember 40, which

is used for the belt of the dressing.

[0147]

In addition, at the belt member 12 side of the belt type

engaging member 40 (i.e. the other edge 12d side of the second

belt member 12b), a second insertion engaging member 42, in which

the belt member is inserted and engaged detachably, is provided.

[0148]

In addition, in the second insertion engaging member 42,

a second belt engaging hole 44 including a slit 42a, in which the

belt member 12 is inserted and engaged detachably, is formed.

[0149]

As a result, through the slit 42a of the second insertion engaging member 42, which is provided to the belt member 12 side of the belt type engaging member 40 having the belt shape, into the second belt engaging hole 44 of the second insertion engaging member 42, the belt member 12b can be inserted and engaged detachably.

[0150]

In this case, as for the second insertion engaging member

42 of the belt type engaging member 40,

as shown in Fig. 1, for instance, the above-mentioned

intermediate engaging member 14 can be used.

As a result, since the number of parts can be reduced, the

cost can be reduced, and it excels in generality.

[0151]

Moreover, as shown in Fig. 1-Fig. 2, as for the belt type

engaging member 40 having this belt shape, it is preferable that

a convexoconcave 40a is formed separately in the predetermined

space.

[0152]

formed to the belt type engaging member 40 of the second engaging

member 38, for instance, the position, in which the portion where

the remaining portion of the belt type engaging member 40 is cut,

can be recognized.

In addition, by forming this convexoconcave 40a to the surface of the buckle type engaging member, the both sides can be confirmed and it can be prevented from providing by making a mistake of the confirmation of the both sides.

[0153]

In addition, in case of this Embodiment, the convexoconcave

40a having the substantially circular shape is formed.

However, the shape, the number, and the disposing position, etc.

can be changed appropriately.

[0154]

Moreover, as shown in Fig. 6 (A) and Fig. 6 (B), it is also

possible that at least one convexoconcave 40b, which is extended

longitudinally along the belt type engaging member 40, is

provided.

[0155]

shown by the arrow of Fig. 1, the plurality of the stretchable

belt members 12 having loop shape (i.e. in case of this Embodiment,

the first belt member 12a and the second belt member 12b) is

detachably coupled mutually through the intermediate engaging

member 14.

[0156]

That is, into the first engaging hole 16a which is formed

to the portion surrounded by the engaging bar main body 14a and

the first engaging bar member 14c, the belt member 12a of one edge of the plurality of the belt members 12 can be detachably inserted through the first slit 18a.

[0157]

14a and the second engaging bar member 14d, the belt member 12b

at the other edge of the plurality of the belt members 12 can be

inserted and engaged through the second slit 18b.

[0158]

Thus, the plural of the belt members 12 (i.e. in case of

this Embodiment, the first belt member 12a and the second belt

member 12b) can be detachably coupled mutually, simply, and

easily.

[0159]

In addition, the first engaging member 20 is detachably

coupled to the one edge of the belt member 12 (i.e. one edge 12c

of the first belt member 12a) that is coupled by the intermediate

engaging member 14.

[0160]

Moreover, the second engaging member 38 is detachably

coupled to the other edge of the belt member 12 (i.e. the other

edge 12d of the second belt member 12b) that is coupled by the

intermediate engaging member 14.

[0161]

Thatis, through the slit 34aofthe firstinsertionengaging

member 34, which is provided to the belt member 12 side of the

buckle type engagingmember 22 (i.e. one edge 12c side of the first

belt member 12a),
