Description

Training belt and rubber ball member

Technical Field

The present invention relates to a training belt and a rubber ball member, each of which is composed of a stretchable belt such as rubber, and which is used for various types of training (hereinafter, simply referred to as "training") in other fields such as exercise, beauty, improvement of health such as lumbago, rehabilitation such as walking disorder, elimination of lack of exercise, prevention of hand and foot, waist and leg, dementia, physical training based on strengthening of back muscles, chest muscles, and the like, body building, and the like.

Background

Conventionally, for such various exercises, for example, an exercise rubber belt, an endless belt, an exercise tube, or the like is used as an exercise tool.

As such a training device, for example, a ring-shaped (loop-shaped) endless belt has been conventionally used as a so-called "chest expander" using an elastic member having elasticity and made of rubber or the like.

In such an endless belt, since the length of the endless belt is constant, it is necessary to prepare endless belts of various lengths depending on the purpose of use, the place of use, the training method, the training strength, the strength (load) of the ring, and the like, which is costly, and it is necessary to select an endless belt for training, which is troublesome and troublesome.

Therefore, patent document 1 (japanese patent application laid-open No. 2017-18243) discloses a training tool that can be used as an endless belt of any length without preparing endless belts of various lengths.

That is, fig. 34 is a perspective view of the training tool shown in patent document 1.

As shown in fig. 34, the training tool 100 disclosed in patent document 1 is configured by connecting a plurality of rings 106 each including a first stretchable member 102 and a second stretchable member 104 longer in the longitudinal direction than the first stretchable member 102, to each other via a joint 108.

Further, for example, the length of the training tool 100 can be changed by variously changing the portion (position) gripped by the left-right hand insertion ring 106, and the strength of the load applied during training can be adjusted.

However, the training tool 100 described in patent document 1 requires a plurality of rings 106 made up of the first stretchable member 102 and the second stretchable member 104 longer in the longitudinal direction than the first stretchable member 102 to be manufactured in advance through the joint 108, and is complicated in structure and high in cost.

Further, the conventional endless belt which is generally sold cannot be used, and the trainer is also burdened in terms of economy, portability, and the like.

Further, the training tool 100 described in patent document 1 may have a problem that, for example, depending on the part (position) gripped by the left and right hand insertion rings 106, an excessive portion is generated at both end portions, which may hinder training or may be entangled around the periphery or other parts of the body.

In addition, when the conventional endless belt is used for exercises such as foot exercises and knee exercises, it is necessary to insert both feet into the ring while sitting on a chair or bending over, which is inconvenient and requires a wide space to some extent.

Therefore, it is not suitable for training during work, learning, etc. while sitting on a chair, training while watching tv, recording video, etc. while sitting on a chair at home, training while moving on a passenger seat or a rear seat of an automobile, a visiting bus, an airplane, a ship, a train, and training on bedding or a bed.

Therefore, the present applicant has provided a training belt in patent document 2 (japanese patent No. 6446654) which can use a conventional commonly available endless belt, can easily connect a plurality of endless belts to each other in an arbitrary length with a simple structure, can reduce costs and man-hours, and is convenient to carry.

Fig. 35 is an exploded perspective view schematically showing the training belt 10 of patent document 2, fig. 36 is an exploded plan view of the training belt 10 of fig. 35, fig. 37 is a partially enlarged cross-sectional view showing the buckle-type locking member 22 as the first locking member 20 of the training belt 10 of fig. 35, and fig. 38 is a cross-sectional view explaining a state where the training belt 10 of fig. 35 is assembled and a rubber ball C is sandwiched between the legs D for training.

Specifically, as shown in fig. 35 to 38, the training belt 10 of patent document 2 includes a plurality of endless belt members 12 (first belt member 12a and second belt member 12b) such as rubber that can be stretched and contracted.

Further, the belt member 12 (the first belt member 12a and the second belt member 12b) is detachably connected to each other by an intermediate locking member 14.

As shown in fig. 35 to 37, the intermediate locking member 14 includes a locking lever body 14a formed in a central portion of the intermediate locking member 14. Further, a first locking lever member 14c and a second locking lever member 14d extending from both ends of the locking lever body 14a via the extending portions 14b at a predetermined interval are provided.

A first locking hole 16a is formed in a portion surrounded by the locked lever main body 14a and the first locking lever member 14 c. A first slit 18a is formed in the first locking hole 16a, and the first slit 18a is used to detachably insert and engage the first belt member 12a at one end of the plurality of belt members 12.

On the other hand, a second locking hole 16b is formed in a portion surrounded by the locked lever main body 14a and the second locking lever member 14 d. A second slit 18b is formed in the second locking hole 16b, and the second slit 18b is used for detachably inserting and engaging the second belt member 12b at the other end of the plurality of belt members 12.

With this configuration, as shown by arrows in fig. 35, the belt members 12a at the one end portions of the plurality of belt members 12 can be removably inserted into and engaged with the first engaging holes 16a formed in the surrounding portions between the engaged lever main body 14a and the first engaging lever member 14c via the first slits 18 a.

As shown by the arrows in fig. 35, the belt members 12b at the other end portions of the plurality of belt members 12 can be removably inserted into and engaged with the second locking hole 16b formed in the portion surrounded by the locked lever main body 14a and the second locking lever member 14d via the second slit 18 b.

In this way, the training belt 10 of patent document 2 is configured to be able to easily and detachably couple the plurality of belt members 12 (the first belt member 12a and the second belt member 12b in this embodiment).

Further, the training belt 10 of patent document 2 includes a first locking member 20 detachably connected to one end portion (one end portion 12c of the first belt member 12 a) of the belt member 12 connected by the intermediate locking member 14.

As shown in fig. 35 to 38, the first locking member 20 is constituted by a buckle-type locking member 22.

The training belt 10 of patent document 2 uses a configuration shown in a partially enlarged cross-sectional view of the buckle-type locking member 22 of fig. 37, for example.

Specifically, the buckle-type locking member 22 is a conventional buckle structure including a buckle main body 24 and a buckle opening/closing member 28, and the buckle opening/closing member 28 is openable and closable relative to the buckle main body 24 in the arrow a direction of fig. 37 via a hinge 26 formed at one end of the buckle main body 24.

As shown in fig. 37, the upper surface of the buckle body 24 in the buckle-type locking member 22 has a plurality of first protrudingly-provided

locking portions

30a and 30b extending in the width direction, and the first protrudingly-provided

locking portions

30a and 30b protrude upward at a predetermined interval.

A plurality of second

projecting engagement portions

32a, 32b are formed on the lower surface of the buckle opening/closing member 28 so as to correspond to the first

projecting engagement portions

30a, 30b, and the second

projecting engagement portions

32a, 32b extend in the width direction and project downward so as to be offset from the first

projecting engagement portions

30a, 30 b.

With this configuration, when the buckle opening/closing member 28 is closed with respect to the buckle body 24 in the direction of arrow a in fig. 37, and the band-shaped locking member 40 constituting the second locking member 38 is inserted into the buckle-shaped locking member 22 in the direction of arrow B in fig. 37, the band-shaped locking member 40 is held between the first projecting locking portions 30a and 30B and the second projecting locking portions 32a and 32B, and the length position of the training belt 10 can be adjusted and held satisfactorily.

The buckle-type locking member 22 includes a first insertion engagement member 34, which is detachably inserted into the locking belt member 12a, on the belt member 12 side (the one end portion 12c side of the first belt member 12 a).

A first strap engaging hole 36 is formed in the first insertion engaging member 34, and the first strap engaging hole 36 includes a slit 34a into which the locking strap member 12a is removably inserted.

With this configuration, the training belt 10 of patent document 2 is configured such that the belt member 12 can be detachably inserted into and locked in the first belt engaging hole 36 of the first insertion engaging member 34 via the slit 34a of the first insertion engaging member 34 provided on the belt member 12 side of the buckle type locking member 22.

Further, patent document 2 proposes a slide-fit type first locking member 20.

That is, fig. 44 is a partially exploded plan view of the training belt 10 of patent document 2.

As shown in fig. 44, in the training belt 10 described in patent document 2, the first locking member 20 is composed of a slide-fit type concave locking member 50 and a convex locking member 56.

Two female engagement holes 50a, into which male engagement portions 56a of male engagement members 56, which will be described later, are detachably engaged, are formed in the female engagement member 50.

On the other hand, the convex locking member 56 is integrally provided with a second insertion engaging member 42 detachably inserted into the locking belt member 12b on the belt member 12 side of the convex locking member 56 (the other end 12d side of the second belt member 12 b).

The slit 42a of the second insertion engagement member 42 is formed between the convex engagement portions 56a of the convex engagement member 56.

With this configuration, the ring-shaped locking member 50 and the male locking member 56 of the locking slide-fit type (the male engaging portion 56a of the male locking member 56 is detachably engaged with the female engaging hole 50a of the female locking member 50) are locked.

The training belt 10 of patent document 2 configured as described above is assembled with the training belt 10, for example, as shown in fig. 38, and training can be performed with the rubber ball C sandwiched between the legs D (for example, thighs) for training.

That is, the leg D can be used for training of the entire leg by applying a load in a direction of opening the leg D outward in a direction indicated by an arrow E in fig. 38 or by applying a load by compressing the rubber ball C in a direction indicated by an arrow F in fig. 38.

In addition to such training, the present invention can be applied to various training methods shown in fig. 7 to 13 of patent document 2.

Further, the present applicant has proposed a training belt and a rubber ball member in which the training effect is improved by further improving patent document 2 in patent document 3 (japanese patent No. 6664719) and patent document 4 (international publication No. WO 2020/039667).

Patent document 4 is equivalent to a combination of the contents of patent documents 2 and 3.

Fig. 39 is a sectional view illustrating a state where the training belt 10 of patent document 3 is assembled and the rubber ball C is sandwiched between the legs D for training, fig. 40 is an exploded perspective view of the third locking member 13, fig. 41(a) is a front view of the locking member body 15 of the third locking member 13, fig. 41(B) is a plan view of the locking member body 15 of the third locking member 13, and fig. 41(C) is a sectional view of the locking member body 15 of the third locking member 13.

As shown in fig. 39, the training belt 10 of patent document 3 further includes at least one third locking member 13 detachably coupled to the belt member 12 of the endless training belt 10.

That is, as shown in fig. 39 to 41(C), the third locking member 13 further includes a locking member body 15 detachably connected to the belt member 12 of the endless training belt 10 as shown in the above-described embodiment.

As shown in fig. 39 to 41(C), the locking member body 15 is composed of a flat plate portion 15a and side plate portions 15b and 15C extending upward on both sides of the flat plate portion 15a in the short-side direction.

As shown in fig. 41(B) to 41(C), the locking member body 15 is in an openable and closable loop shape. That is, the

side plates

15b and 15c are configured to be openable and closable with each other.

As shown in fig. 41(C), for example, the flat plate portion 15a is provided with a protective member 15e made of rubber or the like, so that the belt member 12 is protected from damage.

In this way, as in the above-described embodiment, the belt members (12a, 12b) of the endless training belt 10 are detachably connected to the endless portion of the locking member body 15.

Further, as shown in fig. 39 to 41(C), locking holes 15d are formed in the side plate portions 15b and 15C.

As shown in fig. 40, the third locking member 13 includes a belt coupling portion 17 that detachably couples the other endless stretchable belt member 12 e.

The belt connecting portion 17 is configured to be detachably connected to the locking member body 15. That is, in the case of this embodiment, as shown in fig. 36, the belt connecting portion 17 is an annular locking member, and an openable and closable opening and closing member 17a and a circular hole 17b are formed.

Further, an insertion engagement member 19 into which the locking belt member 12e is detachably inserted is provided on the belt member side of the belt connecting portion 17, that is, on the other endless stretchable belt member 12 e.

The insertion engagement member 19 is substantially annular, and has a lock engagement mechanism 21 at an end thereof, which can be opened and closed by the opening and closing portion 19a and can be engaged therewith. For example, the locking mechanism is configured to be lockable by a thumb screw 21 a.

That is, the training belt 10 of patent document 3 is configured such that the locking mechanism 21 is released or locked, and the open/close portion 19a is opened and closed, and the circular hole 19b is opened and closed via the open/close portion 19a, whereby another endless stretchable belt member 12e can be detachably connected.

The training belt 10 of patent document 3 is configured such that, for example, as shown in fig. 38 of patent document 3, if other endless stretchable belt members 12e are used for both legs, it is possible to perform comprehensive exercise and exercises such as wrist, waist and leg, and it is extremely convenient.

Further, in the training belt 10 of patent document 3, a rubber ball member used together with the training belt 10 is proposed.

That is, fig. 42 is a perspective view of the rubber ball member 80 of patent document 3, and fig. 43 is a cross-sectional view illustrating a state in which the training belt 10 of patent document 3 is assembled using the rubber ball member 80 of patent document 3, and the rubber ball member 80 is sandwiched between the legs D for training.

As shown in fig. 42, a rubber ball member 80 of patent document 3 includes a rubber ball member main body 82 made of a rubber ball having a known shape.

The rubber ball member body 82 is provided with an air inlet 82a having a known structure, and an open/close hole 82c in addition to the air inlet 82 a. The opening/closing hole 82c is provided with an openable/closable lid member 82 b.

The opening/closing hole 82c is closed by the cover member 82b, so that air introduced through the air inlet 82a of the rubber ball member body 82 does not leak to the outside.

The rubber ball member 80 includes a balloon member 84 detachably inserted into the opening/closing hole 82c of the rubber ball member body 82. The balloon member 84 includes a balloon member main body 86 formed of a known balloon.

As shown in fig. 42, the balloon member 84 includes a nozzle member 88 attached to an air port 86a of the balloon member body 86.

Further, as for the nozzle member 88, a base end portion 88a of the nozzle member 88 is attached to the air port 86a of the balloon member main body 86.

In this embodiment, the base end portion 88a of the nozzle member 88 has a substantially dome shape, and an opening portion 88b is formed in the central portion thereof.

As shown in fig. 43, the nozzle member 88 includes a tip portion 88c having a nozzle shape. A plurality of air holes 88d are formed in the tip end portion 88c, and the air holes 88d are configured to communicate with the opening portion 88 b.

The front end 88c of the nozzle member 88 is rotatably inserted into the opening/closing hole 82c of the rubber ball member body 82.

The rubber ball member 80 of patent document 3 configured as above is used as follows.

First, air is introduced into the rubber ball member body 82 through the air inlet 82a of the rubber ball member body 82 by using a well-known air pump for a ball or the like, and the rubber ball member body 82 is inflated.

At this time, the opening/closing hole 82c is closed by the cover member 82b, so that the air introduced through the air introduction port 82a of the rubber ball member body 82 does not leak to the outside.

Thereafter, the lid member 82b is opened, and the tip end portion 88c of the nozzle member 88 is inserted into a predetermined position (a position where air in the rubber ball member body 82 does not leak to the outside) in the opening/closing hole 82 c.

Thus, when the rubber ball member main body 82 is externally pressurized, air in the rubber ball member main body 82 moves to the balloon member main body 86 through the air hole 88d formed in the distal end portion 88c of the nozzle member 88 and the opening portion 88b of the base end portion 88a of the nozzle member 88, and the balloon member main body 86 inflates.

In this case, as shown in fig. 43, the training belt 10 of the present invention may be assembled by using the rubber ball member 80 of the present invention, and may be used in a state where the rubber ball member 80 is sandwiched between the legs D for training.

In this case, the training belt 10 is used to apply pressure to the rubber ball member body 82 from the outside, so that the air inside the rubber ball member body 82 moves to the balloon member body 86 through the air hole 88d formed in the distal end portion 88c of the nozzle member 88 and the opening portion 88b of the base end portion 88a of the nozzle member 88, and the balloon member body 86 inflates.

With this configuration, the rubber ball member 80 is used to apply pressure to the rubber ball member main body 82 from the outside, so that air inside the rubber ball member main body 82 moves to the balloon member main body 86 through the air hole 88d formed in the distal end portion 88c of the nozzle member 88 and the opening portion 88b of the base end portion 88a of the nozzle member 88, and the balloon member main body 86 inflates.

On the other hand, by externally weakening the pressure to the rubber ball member main body 82, the rubber ball member main body 82 moves in the expansion direction by the elasticity of the rubber ball member main body 82.

In this configuration, the air in the balloon member body 86 moves into the rubber balloon member body 82 through the opening 88b of the base end portion 88a of the nozzle member 88 and the air hole 88d formed in the tip end portion 88c of the nozzle member 88, and the rubber balloon member body 82 expands and the balloon member body 86 collapses.

With such a configuration, the balloon member main body 86 is configured to bulge or collapse during various exercises and exercises such as leg exercises and grip strength exercises, and therefore serves as a reference for the exercise, which is extremely convenient.

Problems to be solved by the invention

However, in the training belt 10 described in patent document 2, the first locking member 20 is a buckle-type locking member 22, and is a conventional buckle structure having a buckle body 24 and a buckle opening/closing member 28, and the buckle opening/closing member 28 is openable and closable relative to the buckle body 24 in the direction of arrow a in fig. 37 via a hinge 26 formed at one end of the buckle body 24.

Therefore, the buckle-type locking member 22 having such a conventional buckle structure is complicated in structure and high in cost.

Further, in the buckle-type locking member 22, since it is necessary to insert the band-shaped buckle-type locking member 40 constituting the second locking member 38 into the buckle-type locking member 22 in the direction of arrow B in fig. 37 and to close the buckle opening/closing member 28 and lock it to the buckle body 24 in the direction of arrow a in fig. 37, the operation of attaching and detaching is complicated and troublesome.

In the first locking member 20 of the slide-fit type of the training belt 10 described in patent document 2, when the concave locking member 50 and the convex locking member 56 are locked, a finger may hit the distal end side of the convex locking member 56, and the finger may be erroneously clamped.

Further, the first locking member 20 of the slide-fit type of the training belt 10 described in patent document 2 may erroneously release the locked state between the concave locking member 50 and the convex locking member 56 in a state where the extendable and contractible belt member 12 is stretched.

As shown in fig. 39 to 41(C) of patent document 3, in the training belt 10 of patent document 3, the structure of the third locking member 13 detachably connected to the belt member 12 of the endless training belt 10 is complicated.

That is, the third locking member 13 of patent document 3 requires a complicated structure such as the openable and closable opening/closing member 17a and the circular hole 17b with the connecting portion 17 and a complicated structure such as the opening/closing portion 19a into which the engaging member 19 is inserted and the thumb screw 21a as the locking and locking mechanism 21, which is costly.

In the training belt 10 of patent document 3, the locking/locking mechanism 21 is released or locked, and the opening/closing portion 19a is opened and closed to open and close the circular hole 19b via the opening/closing portion 19a, thereby making it complicated to detachably connect the other endless stretchable belt member 12 e.

As shown in fig. 39 to 41(C) of patent document 3, in the training belt 10 of patent document 3, the structure of the locking member body 15 detachably connected to the belt member 12 of the endless training belt 10 is a complicated structure.

That is, as shown in fig. 39 to 41(C) of patent document 3, in the training belt 10 of patent document 3, the locking member body 15 needs a complicated structure such as the flat plate portion 15a, the side plate portions 15b and 15C extending upward on both sides in the short side direction of the flat plate portion 15a, and the protective member 15e, and the cost is high.

Further, the

side plate portions

15b and 15c must be detachably connected to the belt members (12a and 12b) of the endless training belt 10 by opening and closing each other, which makes the operation complicated.

Further, as shown in fig. 42 to 43, in the rubber ball member 80 of patent document 3, in addition to the air inlet 82a of the rubber ball member main body 82, the opening and closing hole 82c of the rubber ball member main body 82 must be provided, and the air inlet 82a, the cover member 82b, and the like have complicated structures, which are costly and complicated in operation.

Further, a commercially available general-purpose rubber ball cannot be used as it is as the rubber ball member body 82, and versatility is poor.

On the other hand, in the rubber ball member 80 of patent document 3, the nozzle member 88, the tip portion 88c, the plurality of air holes 88d, and the like are required to be provided in the balloon member 84 in accordance with the air inlet 82a of the rubber ball member main body 82, and the structure is complicated and the cost is high.

In view of the above-described situation, an object of the present invention is to provide a training belt that can utilize a conventional commonly available endless belt, can easily connect a plurality of endless belts to each other in an arbitrary length with a simple structure, can reduce costs and man-hours, and is convenient to carry.

Further, an object of the present invention is to provide a training belt which can be easily used as an endless belt of various lengths depending on, for example, the purpose of use, the place of use, the training method, the training strength, the strength (load) of the loop, and the like.

Further, an object of the present invention is to provide a training belt which does not require both feet to be inserted into a ring for use while sitting on a chair or bending down, as in the case of a conventional endless belt used for training of feet, knees, or the like, can be used as a belt, is convenient, and can be used even in a narrow place.

It is another object of the present invention to provide a training belt and a rubber ball member suitable for training during work or learning while sitting on a chair, training while watching tv or recording video while sitting on a chair at home, training while traveling on a passenger seat or a rear seat of an automobile, a bus, an airplane, a ship, a train, and training on bedding or a bed.

Further, an object of the present invention is to provide a training belt and a rubber ball member which do not cause a finger to hit the tip side of the convex locking member 56 and erroneously pinch the finger when the concave locking member 50 and the convex locking member 56 are locked, as in the slide-fit type first locking member 20 of the training belt 10 described in the conventional patent document 2.

Further, another object is to provide a training belt and a rubber ball member which prevent the locked state between the female locking member 50 and the male locking member 56 from being erroneously released in a state where the extendable and retractable belt member 12 is stretched, as in the slide-fit type first locking member 20 of the training belt 10 described in patent document 2.

Further, the present invention aims to provide a training belt which is not complicated in structure as the third locking member 13 and the locking member body 15 of the conventional patent document 3, and which can easily detachably connect other endless belt members 12e which are stretchable and contractible.

Further, the training belt of the present invention is characterized in that,

two of the third locking members are provided to one of the other endless belt members which is freely extendable and retractable,

one end of each of the other endless belt members which are freely extendable and retractable is engaged with the belt engaging hole of the belt connecting member of each of the third engaging members.

With this configuration, since two third locking members are provided for one of the other endless stretchable belt members, and one end portion of the other endless stretchable belt member is locked to the belt locking hole of the belt connecting member of each of the third locking members, it is possible to provide a training belt which can easily detachably connect the other endless stretchable belt member 12 e.

Further, the training belt of the present invention is characterized in that,

one end of each of the other endless belt members which are freely extendable and contractible is configured to be fastened and locked to the belt engaging hole of the belt connecting member of each of the third locking members.

With this configuration, since two third locking members are provided for one of the other endless stretchable belt members, and one end portion of the other endless stretchable belt member is locked to the belt locking hole of the belt connecting member of each third locking member, it is possible to provide a training belt which can easily and detachably connect the other endless stretchable belt member 12 e.

With this configuration, since the one end of the other endless stretchable belt member is detachably inserted into the first belt engaging hole and the other end of the other endless stretchable belt member is detachably inserted into the second belt engaging hole, the other endless stretchable belt member 12e can be easily detachably connected to the training belt.

the first band engaging hole has a slit hole shape with different widths, and the enlarged diameter portion of the other end of the other annular band member that is freely extendable and retractable is detachably engaged with the narrow width portion of the slit hole.

With this configuration, since the first band engaging hole has a slit hole shape with different widths, and the enlarged diameter portion is formed at the other end of the other annular band member which is freely extendable and retractable, and the enlarged diameter portion is detachably engaged with the narrow portion of the slit hole, it is possible to provide a training band in which the other annular band member 12e which is freely extendable and retractable can be more easily detachably coupled.

Further, the training belt of the present invention is characterized in that,

the second belt engaging hole has a slit hole shape with different widths, and the enlarged diameter portion of the other end of the other annular stretchable belt member is detachably engaged with the narrow width portion of the slit hole.

With this configuration, since the second belt engaging hole has a slit hole shape with different widths, and the enlarged diameter portion is formed at the other end of the other endless belt member which can be extended and contracted, and the enlarged diameter portion is detachably engaged with the narrow portion of the slit hole, it is possible to provide a training belt which can more easily and detachably connect the other endless belt member 12e which can be extended and contracted.

Further, the rubber ball member of the present invention is provided with a rubber ball member main body,

the rubber ball component body is provided with an air inlet of the rubber ball component body,

an air hole is formed at the front end of the nozzle member,

the balloon member body is configured to be inflated by applying pressure from the outside to the rubber ball member body using a training belt, thereby moving air inside the rubber ball member body to the balloon member body through an air hole formed at a distal end portion of the nozzle member.

With this configuration, when the rubber ball member is used to apply pressure to the rubber ball member body from the outside, air inside the rubber ball member body moves to the balloon member body through the air hole formed at the tip end of the nozzle member, and the balloon member body inflates.

On the other hand, by externally weakening the pressure to the rubber ball member main body, the rubber ball member main body moves in the expansion direction by the elasticity of the rubber ball member main body.

In this configuration, the air in the balloon member body moves into the rubber balloon member body through the air hole formed in the distal end portion of the nozzle member, and the rubber balloon member body expands and shrinks.

With this configuration, the balloon member body expands and contracts in various exercises and exercises such as leg exercises and grip strength, and therefore becomes a reference for the exercise, which is extremely convenient.

Further, for example, when the rubber ball member body which sandwiches the rubber ball member between the two crotch portions is moved to close the two crotch portions, the air in the rubber ball member body is moved to the balloon member body through the air hole formed at the tip end portion of the nozzle member by applying pressure to the rubber ball member body from the outside by the pressing force of the movement, and the balloon member body is inflated.

Then, the movement is stopped, for example, this time during the movement to open the two crotch or rest, air is moved into the rubber ball member body via the air hole formed at the front end portion of the nozzle member by the pressure of the balloon member body, and the rubber ball member body is inflated again.

By such repetition, a continuous motion using the rubber ball member can be realized.

Further, since only the tip end portion of the nozzle member needs to be detachably inserted into the air inlet port of the rubber ball member main body, it is possible to provide a training belt and a rubber ball member which do not require the provision of the opening and closing hole 82c of the rubber ball member main body 82 in addition to the air inlet port 82a of the rubber ball member main body 82 as in the rubber ball member 80 of patent document 3 in the related art, and which can directly use a commercially available general-purpose rubber ball as the rubber ball member main body 82, and which can directly use an air needle for an air pump for injecting air into the rubber ball as the commercially available general-purpose nozzle member, and which is excellent in versatility, simple in structure, low in cost, simple in operation, and universal in use.

In the rubber ball member of the present invention, a nozzle attachment member to which the nozzle member is detachably attached is attached to an air port of the balloon member main body of the balloon member.

With this configuration, since the nozzle attachment member to which the nozzle member is detachably attached is attached to the air port of the balloon member main body of the balloon member, it is possible to provide a training belt and a rubber ball member, which can use a commercially available air needle for an air pump for injecting air into a rubber ball, and which is easy to handle and versatile.

a female screw portion is formed at a distal end portion of the nozzle mounting member,

the nozzle member is detachably mounted to the balloon member body of the balloon member by screwing the external thread portion of the nozzle member into the internal thread portion of the nozzle mounting member.

With this configuration, since the nozzle member can be detachably attached to the balloon member main body of the balloon member by screwing the male screw portion of the nozzle member and the female screw portion of the nozzle attachment member, it is possible to provide a training belt and a rubber ball member, and therefore, a commercially available air needle for an air pump for injecting air into a rubber ball can be used as the nozzle member, and the operation is simpler and the versatility is provided.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, the plurality of endless stretchable band members are detachably connected to each other via the intermediate locking member.

The first locking member is detachably connected to one end of the belt members connected by the intermediate locking member.

The second locking member is detachably connected to the other end of the belt member connected by the intermediate locking member.

That is, the belt member can be removably inserted into and locked in the first belt engaging hole of the first insertion engaging member through the slit of the first insertion engaging member provided on the belt member side of the hook-type locking member of the first insertion engaging member.

The belt member can be removably inserted into the second belt engaging hole locked in the second locking member through the slit of the second locking member.

The hook body of the hook-type engaging member of the first engaging member is configured to be brought into a loop shape by being engaged with the hook engaging hole of the second engaging member in this state.

Therefore, it is possible to provide a training belt that can use an existing commonly-sold endless belt as a belt member, can connect a plurality of endless belts (belt members) to each other in an easily detachable and attachable manner in an arbitrary length with a simple structure, can reduce costs and man-hours, and is convenient to carry.

Further, it is possible to provide a training belt that can be easily used in endless belts of various lengths depending on, for example, the purpose of use, the site of use, the training method, the training strength, the strength (load) of the ring, and the like.

Further, it is possible to provide a training belt which can be used as a belt, is convenient, and can be used in a narrow place without inserting both feet into a ring while sitting on a chair or bending, as in the case of a conventional endless belt used for training of foot exercise, knee exercise, and the like.

Further, it is possible to provide a training belt suitable for training during work, learning, and the like while sitting on a chair, training while sitting on a chair at home, television, video, and the like, training while moving on a passenger seat or a rear seat of an automobile, a bus, an airplane, a ship, a train, and training on bedding or a bed, for example.

Further, since the training belt is configured to be looped only by engaging the hook body of the hook-type engaging member of the first engaging member with the hook engaging hole of the second engaging member, the training belt can be connected to any length with a simple structure and easily attached and detached, and can be carried conveniently with reduced cost and man-hours.

Further, according to the present invention, unlike the slide-fit type first locking member 20 of the training belt 10 described in the conventional patent document 2, when the concave locking member 50 and the convex locking member 56 are locked, a finger does not come into contact with the distal end side of the convex locking member 56 and erroneously pinch the finger.

Further, according to the present invention, unlike the slide-fit type first locking member 20 of the training belt 10 described in the conventional patent document 2, the locked state between the concave locking member 50 and the convex locking member 56 is not erroneously released in a state where the extendable and contractible belt member 12 is stretched.

Further, according to the present invention, at least one third engaging member is provided, and the third engaging member is detachably connected to a belt member of an endless training belt.

In addition, a belt member, which is an endless training belt, is detachably inserted into the first belt insertion hole of the locking member body.

On the other hand, the other endless stretchable belt member can be detachably inserted into and locked in the belt engaging hole through the slit of the belt connecting member of the hook-type connecting member of the belt connecting portion.

Further, by engaging the hook body of the hook-type coupling member with the coupling portion with the second tape insertion hole of the engaging member body of the third engaging member, it is possible to easily couple and uncouple the other endless belt member for training use to the belt member forming the endless belt member for stretching and contracting, and it is extremely convenient.

Further, according to the present invention, the rubber ball member is used, and by applying pressure to the rubber ball member main body from the outside, air inside the rubber ball member main body moves to the balloon member main body through the air hole formed at the tip end portion of the nozzle member, and the balloon member main body inflates.

With such a configuration, for example, in various exercises and exercises such as leg exercises and grip strength exercises, the balloon member main body expands and contracts, and therefore becomes a reference for the exercise, which is extremely convenient.

Further, for example, when the rubber ball member body sandwiching the rubber ball member between the two crotch portions is moved to close the two crotch portions, the air inside the rubber ball member body is moved to the balloon member body through the air hole formed at the front end portion of the nozzle member by applying pressure to the rubber ball member body from the outside by the pressing force of the movement, and the balloon member body is inflated.

Then, the movement is stopped, for example, this time during the movement to open the two crotch or rest, air is moved into the inside of the rubber ball member body by the pressure of the balloon member body via the air hole formed at the front end portion of the nozzle member, and the rubber ball member body is inflated again.

Further, since only the tip end portion of the nozzle member needs to be removably inserted into the air inlet port of the rubber ball member body, it is possible to provide a training belt and a rubber ball member which do not require the provision of the opening and closing hole 82c of the rubber ball member body 82 in addition to the air inlet port 82a of the rubber ball member body 82 as in the conventional rubber ball member 80 of patent document 3, and which are capable of directly using a commercially available general-purpose rubber ball as the rubber ball member body 82, and which are capable of directly using an air needle for an air pump for injecting air into the rubber ball as the commercially available general-purpose nozzle member, and which are excellent in versatility, simple in structure, low in cost, simple in operation, and versatile.

12f and 12g of the belt member 12e into the belt engaging holes 21 of the belt connecting member 19c, folding back, and fastening by welding, bonding, sewing, or the like may be employed, although not shown, and the method is not limited at all.

Further, since the one end portion 12f (12g) of the other endless stretchable belt member 12e can be fastened and locked to the belt engaging hole 21b of the belt connecting member 19c of each third locking member 13, the other endless stretchable belt member 12e can be connected easily and detachably to the training belt 10.

(example 3)

The training belt 10 of the present embodiment has basically the same configuration as the training belt 10 of embodiment 2 shown in fig. 12 to 15, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 16, in the training belt 10 of the present embodiment, the belt connecting member 19c of the belt connecting portion 17 is formed with a first belt engaging hole 23, and the first belt engaging hole 23 is used to detachably insert and engage one end portion 12f (12g) of another endless stretchable belt member 12 e.

Further, a second belt engaging hole 25 is formed in the connecting member 19 of the belt connecting portion 17, and the second belt engaging hole 25 is detachably inserted and engaged with the other end portion 12f (12g) of the other endless stretchable belt member 12 e.

With this configuration, the training belt 10 can be provided in which the one end portion 12f of the other endless stretchable belt member 12e is detachably inserted into and engaged with the first belt engaging hole 23, and the other end portion 12g of the other endless stretchable belt member 12e is detachably inserted into and engaged with the second belt engaging hole 25, so that the other endless stretchable belt member 12e can be easily and detachably coupled.

In this embodiment, as shown in fig. 16, one end portion 12f (12g) of another endless stretchable belt member 12e is detachably fastened and locked to the first belt engaging hole 23.

The other end portion 12f (12g) of the other endless belt member 12e which is freely extendable and contractible is detachably fastened and locked to the second belt engaging hole 25.

With this configuration, the training belt 10 can be provided in which the one end portion 12f (12g) of the other endless stretchable belt member 12e is detachably fastened and locked to the first belt engaging hole 23, and the other end portion 12f (12g) of the other endless stretchable belt member 12e is detachably fastened and locked to the second belt engaging hole 25, so that the other endless stretchable belt member 12e can be easily and easily connected.

In this case, as a method of fastening and locking, as shown in fig. 16, in addition to fastening by a tether, for example, although not shown, a method of inserting the one end portion 12f (12g) of the belt member 12e into the first belt engaging hole 23 and the second belt engaging hole 25 of the belt connecting member 19c, folding back, and fastening by welding, bonding, sewing, or the like may be employed without any limitation.

In this case, in the training belt 10 of this embodiment, the second belt engaging hole 25 has a slit hole shape with different widths, that is, in this embodiment, it is formed of a narrow width portion 25a and a wide width portion 25b having a substantially keyhole shape.

The other end portion 12f (12g) of the other endless stretchable band member 12e is detachably engaged with the narrow portion 25a of the slit hole.

With this configuration, the second band engagement hole 25 has a slit hole shape with different widths, that is, a narrow width portion 25a and a wide width portion 25 b.

As a result, as shown in fig. 16, a diameter-enlarged portion 27a is formed at the other end portion 12f (12g) of the other endless belt member 12e which is freely extendable and contractible, and this diameter-enlarged portion 27a is inserted into the second belt engaging hole 25 from the thick portion 25b and detachably engaged with the narrow portion 25a of the slit hole of the second belt engaging hole 25.

Therefore, the training belt 10 can be provided in which the other endless stretchable belt member 12e can be easily detachably connected.

In this case, as a method for manufacturing the enlarged diameter portion 27a, for example, a method of fixedly connecting a knot made in a tether manner or an enlarged diameter member made of another member to the other end portion 12f (12g) of the other annular stretchable band member 12e, and the like can be adopted, and there is no particular limitation.

Then, as shown in fig. 16, the hook body 17c of the hook-type coupling member of the belt coupling portion 17 is locked in the second belt insertion hole 15g of the locking member body 15 of the third locking member 13.

As a result, as shown in fig. 12, the other endless stretchable belt member 12e is detachably connected to the belt member 12 of the endless training belt 10.

Although not shown, it is preferable to reduce the elliptical shape of the first band engagement hole 23 to increase the strength around the first band engagement hole 23.

Further, when the hook body 17c of the hook-type coupling member with the coupling portion 17 is locked in the second tape insertion hole 15g of the locking member body 15 of the third locking member 13, it is preferable that the remaining space of the second tape insertion hole 15g is as small as possible so that the hook body 17c is less likely to fall off the second tape insertion hole 15 g.

(example 4)

Fig. 17 is an exploded perspective view of another embodiment of the third locking member 13 of the training belt 10 according to the present invention, and fig. 18 is a view of the coupling member 19 of the belt coupling portion 17 of the third locking member 13 of fig. 17, as viewed in the direction B of fig. 17.

The training belt 10 of the present embodiment has basically the same configuration as the training belt 10 of embodiment 3 shown in fig. 16, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

In the training belt 10 of example 3 shown in fig. 16, the first belt engaging hole 23 and the second belt engaging hole 25 are formed on the same plane of the substantially flat plate-shaped coupling member 19 of the belt coupling portion 17.

In contrast, as shown in fig. 17 to 18, in the training belt 10 of the present embodiment, a bent portion 27 is formed in a portion of the substantially flat plate-shaped coupling member 19 of the belt coupling portion 17 so as to protrude in a direction opposite to the hook main body 17c of the hook shape.

The bent portion 27 is formed with a second band engagement hole 25, and the shape of the second band engagement hole 25 is a slit hole shape having different widths, that is, a narrow width portion 25a and a wide width portion 25 b.

Also, in this embodiment, as shown in fig. 18, the width of the second tape engagement hole 25 is formed to be gradually narrowed, thereby forming a narrow width portion 25a and a wide width portion 25 b.

In the training belt 10 configured as described above, as shown in fig. 17 to 18, the enlarged diameter portion 27a is formed at the other end portion 12f (12g) of the other endless belt member 12e which is freely extendable and contractible, and the enlarged diameter portion 27a is inserted into the second belt engaging hole 25 from the wide width portion 25b, so that the narrow width portion 25a of the slit hole of the second belt engaging hole 25 is more easily detachably locked.

Therefore, the training belt 10 can be provided in which the other endless stretchable belt member 12e can be connected more easily and detachably.

In this embodiment, as shown in fig. 17 to 18, the enlarged spherical portion 17d is formed at the base end portion of the band connecting portion 17, and thereby the one end portion 12f (12g) of the band member 12e is inserted into the first band engaging hole 23 and is more firmly locked by, for example, fastening.

(example 5)

Fig. 19 is a perspective view of the rubber ball 80 of the present invention, and fig. 20 is a cross-sectional view illustrating a state in which the training belt 10 of the present invention is assembled by using the rubber ball 80 of the present invention, and the rubber ball 80 is sandwiched between the legs D for training.

The training belt 10 of the present embodiment has basically the same configuration as the training belt 10 of the embodiment shown in fig. 1 to 18, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 19, the rubber ball member 80 of the present invention includes a rubber ball member main body 82 formed of a rubber ball having a known shape.

An air inlet 82a of a known structure is formed in the rubber ball member main body 82.

The rubber ball member 80 further includes a balloon member 84 detachably inserted into the air inlet 82a of the rubber ball member body 82. The balloon member 84 includes a balloon member main body 86 formed of a known balloon.

As shown in fig. 19, the balloon member 84 includes a nozzle member 88 attached to an air port 86a of the balloon member body 86.

As shown in fig. 20, the nozzle member 88 includes a nozzle-shaped tip portion 88 c. A plurality of air holes 88d are formed in the tip end portion 88c, and the air holes 88d are configured to communicate with the opening portion 88 b.

The front end 88c of the nozzle member 88 is detachably inserted into the air inlet 82a of the rubber ball member body 82.

Then, the front end portion 88c of the nozzle member 88 is inserted into a predetermined position in the air introduction port 82a of the rubber ball member body 82 (a position where air in the rubber ball member body 82 does not leak to the outside).

In this case, as shown in fig. 20, the training belt 10 of the present invention is assembled by using the rubber ball member 80 of the present invention, and may be used in a state where the rubber ball member 80 is sandwiched between the legs D for training.

With this configuration, the balloon member main body 86 expands and contracts during various exercises and exercises such as foot exercises and grip strength exercises, and therefore becomes a reference for the exercise, which is extremely convenient.

For example, when the rubber ball body 82 of the rubber ball 80 is sandwiched between two crotch parts and a closing movement is performed, the rubber ball body 82 is pressed from the outside by the pressing force of the movement, and the air in the rubber ball body 82 moves to the balloon body 86 through the air hole 88d formed in the distal end portion 88c of the nozzle member 88, and the balloon body 86 inflates.

Then, the movement is stopped, for example, this time during the movement to open the two thighs or rest, air is moved into the inside of the rubber ball member body 82 via the air hole 88d formed at the front end portion 88c of the nozzle member 88 by the pressure of the balloon member body 86, and the rubber ball member body 82 is inflated again.

By such repetition, a continuous movement using the rubber ball member 80 can be realized.

Further, since the front end portion 88c of the nozzle member 88 is only required to be detachably inserted into the air inlet 82a of the rubber ball member body 82, it is not necessary to provide the opening and closing hole 82c of the rubber ball member body 82 in addition to the air inlet 82a of the rubber ball member body 82 as in the rubber ball member 80 of the conventional patent document 3, and a commercially available rubber ball can be used as the rubber ball member body 82, so that the cost can be reduced.

(example 6)

The training belt 10 of this embodiment has basically the same configuration as the training belt 10 of embodiment 5 shown in fig. 19 to 20, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

In the training belt 10 of the present embodiment, an air needle for a commercially available general-purpose air pump for injecting air into a rubber ball can be used as it is as the nozzle member 88.

As shown in fig. 21, in the training belt 10 of the present embodiment, the rubber ball member 80 is attached with the nozzle attachment member 81 to which the nozzle member 88 is detachably attached to the air port 86a of the balloon member body 86 of the balloon member 84.

With this configuration, since the nozzle attachment member 81 to which the nozzle member 88 is detachably attached is attached to the air port 86a of the balloon member main body 86 of the balloon member 84, the air needle for the air pump for injecting air into the rubber ball, which is commercially available and commonly used, can be used as the nozzle member 88, and the training belt 10 and the rubber ball member 80 can be provided with simple operation and versatility.

As shown in fig. 21, the rubber ball member of this embodiment has a male screw portion 83 formed at the distal end portion of the nozzle member 88 opposite to the proximal end portion 88a, and a female screw portion 85 formed at the proximal end portion of the nozzle attachment member 81.

Thus, the nozzle member 88 can be detachably attached to the balloon member main body 86 of the balloon member 84 by screwing the male screw portion 83 of the nozzle member 88 and the female screw portion 85 of the nozzle attachment member 81.

Further, a balloon fixing member 86b, for example, a ring member, which is detachably attached to the nozzle attachment member 81 with the balloon member main body 86 of the balloon member 84 attached to the air port 86a of the balloon member main body 86, is attached.

With this configuration, the training belt 10 and the rubber ball member 80 can be provided, and the nozzle member 88 can be detachably attached to the balloon member main body 86 of the balloon member 84 by screwing the male screw portion 83 of the nozzle member 88 and the female screw portion 85 of the nozzle attachment member 81, so that an air needle for an air pump for injecting air into a rubber ball, which is commercially available and commonly used, can be used as the nozzle member 88, and the operation is simpler and the versatility is higher.

(example 7)

The training belt 10 of the present embodiment has basically the same configuration as the training belt 10 of the embodiment shown in fig. 16 to 20, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 22, the training belt 10 of the present embodiment includes a pair of left and right third locking members 13 in total.

The belt connecting portion 17 and the locking member body 15 of example 3 shown in fig. 16 are used as the third locking member 13.

That is, as shown in fig. 22, in the training belt 10 of the present embodiment, the belt connecting member 19c of the belt connecting portion 17 is formed with a first belt engaging hole 23, and the first belt engaging hole 23 is detachably inserted and engaged with one end portion 12f (12g) of another endless stretchable belt member 12 e.

With this configuration, the one end portion 12f of the other endless stretchable belt member 12e is detachably inserted and locked in the first belt engaging hole 23, and the other end portion 12g of the other endless stretchable belt member 12e is detachably inserted and locked in the second belt engaging hole 25.

Further, in this case, although not shown, in the training belt 10 of this embodiment, as in embodiment 3 shown in fig. 16, the shape of the second belt engaging hole 25 is a slit hole shape having different widths, that is, a narrow width portion 25a and a wide width portion 25 b.

The other end portion 12f (12g) of the other endless stretchable band member 12e is detachably engaged with the narrow portion 25a of the slit hole by, for example, the diameter-enlarged portion 27 a.

In the training belt 10 of the present embodiment, as shown in fig. 22, the belt members 12 are composed of 3 belt members 12 in total, namely, a first belt member 12a, a second belt member 12b, and a third belt member 12 h.

Therefore, as shown in fig. 22, a total of 3 intermediate locking members 14 are provided, and the first belt member 12a, the second belt member 12b, and the third belt member 12h are connected in a ring shape by the 3 intermediate locking members 14.

In the training belt 10 of the present embodiment, as shown in fig. 22, the third belt member 12h is configured to be folded back and fastened to the intermediate locking member 14 disposed in the middle to form a loop.

In the training band 10 of this embodiment, as shown in fig. 22, the base end portion 88a of the nozzle member 88 attached to the air port 86a of the balloon member 84 has an inverted conical shape whose diameter is enlarged from the air port 86a of the balloon member main body 86 toward the inside of the balloon member main body 86, as shown in fig. 24(b) to be described later.

This prevents the base end 88a of the nozzle member 88 from coming off the air port 86a of the balloon member 84.

The training belt 10 of the embodiment thus configured can exhibit substantially the same operational effects as those of the training belt 10 of the embodiment shown in fig. 16 to 20.

(example 8)

The training belt 10 of the present embodiment has basically the same configuration as the training belt 10 of the embodiment shown in fig. 15 to 22, and the same components are denoted by the same reference numerals, and detailed description thereof is omitted.

As shown in fig. 23, in the training belt 10 of the present embodiment, the first locking member 20 is constituted by a slide-fit type concave locking member 50 and a convex locking member 56.

On the other hand, the convex locking member 56 is integrally provided with a second insertion engaging member 42 that is detachably inserted into the locking belt member 12b on the belt member 12 side of the convex locking member 56 (the other end 12d side of the second belt member 12 b).

In this embodiment, the concave locking member 50 itself is formed with a slit 34a into which the locking band member 12a is removably inserted.

With this configuration, the ring-shaped engagement structure is configured by engaging the slide-fit type concave engagement member 50 and the convex engagement member 56 (the convex engagement portion 56a of the convex engagement member 56 is detachably engaged with the concave engagement hole 50a of the concave engagement member 50).

Further, in this embodiment, as shown in fig. 23, a stopper portion 51 is provided outward of the convex locking member 56, and the stopper portion 51 is configured so that the tip side of the convex locking member 56 is not touched by a finger when the concave locking member 50 and the convex locking member 56 are locked.

Then, the hook body 17c of the hook-type coupling member with the coupling portion 17 is locked in the narrow portion 15h of the second tape insertion hole 15g of the locking member body 15 of the third locking member 13.

Thus, the other endless stretchable belt member 12e is detachably connected to the belt member 12 of the endless training belt 10.

With this configuration, the second band insertion hole 15g of the locking member body 15 of the third locking member 13 has a slit hole shape with different widths, that is, in this embodiment, a narrow width part 15h and a wide width part 15i having a substantially keyhole shape.

Thereby, the hook body 17c of the hook-type coupling member with the coupling portion 17 can be locked to the narrow portion of the second tape insertion hole of the locking member body of the third locking member and the narrow portion 15h of the second tape insertion hole 15g of the locking member body 15 of the third locking member 13.

This can prevent the hook main body 17c of the hook-type coupling member with the coupling portion 17 from coming off.

Therefore, the other endless stretchable belt member 12e can be connected to the belt member 12 of the endless training belt 10 more firmly and detachably.
