Description

Description: FIELD OF THE INVENTION The present invention relates to a portable stretching device, and more particularly to an improved portable stretching device for allowing a user to bend forward to provide a stretching effect to muscles of various parts of the body.

[Prior Art] It has been demonstrated that stretching in which a proper load is applied to muscles of various parts of the body to expand the muscles and restore flexibility to muscles or joints is effective for function recovery of muscles and the like.

Such stretching is not only used as a preparatory exercise for sports, but also strengthens muscle strength, relieves pain in various parts of the body such as back pain, or eliminates stiff shoulders,
It is also used to correct the body axis.

Normal stretching is performed by applying a predetermined stretching load to necessary muscles of the body without using an instrument and applying an overload that is not normally used to the muscles.

However, since much experience is required to restore appropriate flexibility without imposing an excessive burden on muscles, in recent years, stretching using a stretching aid has become common.

In the related art, such a stretching device is generally large-scale, such as a stretching bench, which is performed using a training bed.

[Problem to be Solved by the Invention] However, in such a large-sized device, it is possible to give a stretch to all parts of the body, but on the other hand, the device itself becomes a large-sized device, and the device can be easily stretched without choosing a place. There is a drawback that it is difficult to perform stretching and it is difficult to use it for extremely effective muscle strengthening by performing continuous stretching.

The present invention has been made in view of the above conventional problems,
It is an object of the present invention to provide an improved portable stretching device that can obtain a good stretching effect while being a very simple device with excellent portability.

The present invention focuses on the fact that most of the stretching effect in all parts of the body is obtained in a forward bending state, and the device itself is used to keep the position of the body leaning forward, and this device is used. This is characterized in that a stretching effect is given to muscles of almost every part of the body while basically using forward bending exercise.

[Means for Solving the Problems] In order to achieve the above object, a stretch device according to the present invention includes a pair of side plates and both ends of which are supported by the side plates, and a user who can adjust a tilt angle. It is characterized in that it includes a foot support for placing a foot, and finger hooks provided on the both side plates so that a user can grip the side plates in a forward bending state.

[Operation] Therefore, according to the present invention, the user adjusts the foot support to an appropriate angle, puts both feet on this foot support, leans forward and grasps the finger hook, and applies overload in a slightly painful state to each part of the body. Can give a stretching effect.

According to the stretching device of the present invention, it is possible to change the load applied to the muscle in various ways by adjusting the inclination angle of the foot support.

Also, while basically stretching while bending forward,
By stretching the right or left finger on either side or only one of the sides of the finger rest of the side plate, or by changing the gripping direction, a stretching effect can be given to almost any muscle in each part of the body.

In particular, the present invention is extremely effective for stretching the waist, back of thigh, front of thigh, calf, Achilles tendon, neck, back, or abdominal muscle.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an exploded perspective view of a preferred embodiment of the stretching device according to the present invention.

In the figure, a pair of side plates 10 and 12 are made of a plastic plate or the like, and L-shaped brackets 14 and 16 are integrally or firmly connected and fixed to lower ends thereof, and the lower surfaces of the brackets 14 and 16 are placed on the floor surface. Is done.

Base receiving grooves 14a, 16a are provided inside the brackets 14, 16.
Are provided, and a base plate to be described later is
Is inserted into.

In the figure, the base plate is indicated by reference numeral 20 and has a substantially rectangular shape, with both ends having a thickness that allows loose fitting in the base receiving grooves 14a and 16a of the side plates 10 and 12, as described above.

A foot support 30 is hingedly connected to one longitudinal side surface 20a of the base plate 20, and the foot plate 30 has a substantially rectangular shape made of plastic or the like, similarly to the base plate 20.

In the embodiment, a suitable surface treatment or a thin rubber plate is attached to the surface of the foot support 30 to prevent slipping when the user puts both soles on the surface, and such a non-slip is denoted by reference numeral 30a. It is shown.

In the present invention, the angle of inclination of the foot support 30 can be adjusted arbitrarily. In the embodiment, the angle of inclination is determined by screw holes provided on both sides of the tip of the foot support 30.
This is done by changing the fixed position of 30b.

To this end, three screw guides 41, 42, 43 and 51, 52, 53 are provided on both side plates 10, 12, respectively.
These screw guides 41 to 43 and 51 to 53 are preferably formed of metal bushes press-fitted or bonded and fixed to side plates 10 and 12 made of plastic, respectively.

Therefore, with both ends of the base plate 20 inserted into the base receiving grooves 14a and 16a of the side plates 10 and 12, the set screws 61 and 62 are passed through one of the screw guides at an angle position arbitrarily selected from three. Screw hole 30b of plate 30
The foot plate 30 is firmly fixed by the side plates 10 and 12 and the inclination angle thereof is selected.

In the present invention, both side plates 10 and 12 are provided with a finger hanging portion for the user to put a finger in a forward bending state.
0 and 12 are provided respectively, and the side plate 10 is provided with a finger hook 71 at a high position for giving a weak stretching and a finger hook 72 at a low position for giving a strong stretching. On the 12 side, a high position finger rest 73 and a low position finger rest 74 are provided.

FIG. 2 is an explanatory view of the use state of the present embodiment, and is shown as a side view with one side plate 10 removed.

As is clear from the figure, the foot plate 30 is fixed to the screw guide 52, and thereby, an inclination angle of about 25 degrees is set.

In this embodiment, the other screw guide 51 provides a 15-degree inclination angle to the foot support 30 and
53 can similarly provide a 35 degree tilt angle.

In general, in the stretching device according to the present invention, since the stretching is performed with the foot support 30 always inclined, a constant load or more is always applied to the user's Achilles tendon. Setting the angle to 35 degrees or less was preferable in order not to overload the Achilles tendon.

As can be seen from FIG. 2, the foot support 30 allows the user to ride his / her feet together along this inclined surface as shown by 100 in FIG. A finger is placed on either of the finger hooks 73 or 74 of the plate 12, in this embodiment, the index finger and the middle finger, and the side plate 12 is firmly grasped.

Although not shown, it is preferable to similarly hold the side plate 10 with the left finger on the opposite side plate 10 as well.

Of course, as described above, the stretching device according to the present invention exerts a stretching effect on the muscles of all parts of the body, so that the right arm, the left arm or both fingers or only one of the fingers grips the side plate. Thus, a stretching effect can be given to a desired muscle while giving a twist to the body.

In the present embodiment, the foot support 30 has a width enough to place both feet naturally in a flat state, and as a result, both the right arm and the left finger of the user have both side plates at very natural intervals. Stretching can be performed without giving an unnatural force in such a forward bending state to grip the side plates 10 and 12 from both sides because the finger hooks 71 to 74 of the 10, 12 can be gripped.

FIG. 3 shows such an overall stretched state. As is apparent from the figure, the user presses down the foot support with both feet while supporting the body with the stretching device according to the present invention in the forward bending state. While (arrow A), one or both of the side plates 10, 12 are lifted up by a finger as shown by arrow B, whereby a desired stretching action can be exerted on the muscles of each part.

In the present invention, the tilt angle of the foot support 30 can be arbitrarily adjusted. In the embodiment, the inclination can be adjusted in three stages, and in the embodiment, the height of the finger rest is reduced to give a strong stretching. The position and the high position which gives a weak stretching can be selected, thereby performing a total of six levels of stretching force adjustment.

As described above, according to the stretch device of the present invention, unlike a large-scale stretch device using a conventional training bed, it is possible to extremely effectively apply a desired amount to each part of the body while using the forward bending exercise unlike a conventional large-scale stretch device using a training bed. There is an advantage that a stretching effect can be given.

Furthermore, the stretch device in this embodiment further has an extremely effective action in the stored state.

FIG. 4 shows a state in which the stretching device in this embodiment is stored, and FIG. 4 (A) is a plan view thereof.
(B) is a front view, (C) is a rear view, and (D) is a side view.

As is clear from FIG. 4, when storing the stretching device in the present embodiment, first, the set screws 61, 62 are removed, and as shown in FIG. Is detached.

In this state, the base plate 20 and the foot support 30 are folded, and can be almost folded in two.

Next, the two side plates 10 and 12 are alternately positioned at both ends of the foot plate 30 in a manner opposite to the assembled state of FIG.
That is, the left side plate 10 is on the right side, and
The right side plate 12 is moved to the left, and its plate surface is positioned along the plane of the foot support 30 as shown in FIG.

At this time, both brackets 14, 16 are attached to both side plates 10,
Suitable for determining twelve positions.

As shown in FIG. 5, screw holes are provided at both ends on the back side of the foot plate 30. As a result, both side plates 10 and 12 have their screw guides 41 and 51 in the embodiment. The support screw 30 is firmly fixed to the storage screw holes 3cb, 30d provided on the back side of the support 30 by the set screws 61, 62.

FIG. 5 shows the folded state of the base plate 20 and the foot support 30 of the present embodiment in the assembled state. As is apparent from the figure, screw holes 30b and 30d for fixing are provided on the back surface of the foot support 30. Have been.

Therefore, according to the present embodiment, the stretching device can be stored in an extremely thinly folded state, and such a folded device can be easily stored in a small bag or the like.

In the above-described embodiment, the base plate is provided to support the foot support.However, the base plate is removed, and only the foot support is screwed to both side plates at both ends on both sides or to a bayonet or other fixing mechanism. It is also possible to fix the position of the user, and it is possible to sufficiently receive the weight of the user even in the above-described embodiment or such a modified example.

Further, in the present embodiment, even in the event that the foot support is detached, the foot support is provided so as not to be caught by the foot support that falls with the finger resting on the finger rest that gives a strong stretch on the lower side. It is also preferable to retract the finger hook from the entire width.

[Effects of the Invention] As described above, according to the present invention, a user can apply a number of different types of stretching effects to various parts of the body by using its weight and upward pulling force while using a forward bending exercise. It is possible to perform a favorable stretching action while being extremely small by merely putting the user's foot on and placing a finger in a forward bending state.

Further, in the above-described embodiment, there is an advantage that such a small stretch device can be stored in a more portable manner.
