DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an orthosis for health promotion which can be used easily and continuously in ordinary households, and more specifically, a traction stretcher which can obtain health by stretching and stretching the whole body. About.

[0002]

2. Description of the Related Art Conventionally, there are various health promotion appliances used in general homes. One of them is the so-called hanging health device. This health device is a very simple brace that can obtain the whole body's health simply by squeezing and hanging down the grip bar with both hands. However, this type of hanging health device is a device in which both hands hold the grip bar and hang, and while its use is very simple, the entire weight of the user must be supported only by both arms. For this reason, there is a problem that the degree of fatigue is large and it is difficult to use continuously.

[0003] Therefore, as an improved health-enhancing device, a head-side main frame on which the upper body of the body is mounted and a lower body of the body which can be detachably connected and fixed to the head-side main frame are mounted. A leg-side main frame to be provided, a horizontal rod provided below the leg-side main frame, and two leg-side main frames and the horizontal rod provided with an interval equal to both leg widths. A pair of pulleys, two tow ropes spanning the pulleys,
A tow extender is proposed, comprising a weight connected to one end of each of the tow ropes and a leg band connected to the other end, so that the entire body is towed and extended by the tow ropes via the weight. (See Japanese Patent Application Laid-Open No. 7-246253).

[0004] When the above-mentioned traction stretcher is used, a rug such as a futon is laid on a framed frame, a body is laid on the rug, and the upper body is fixed by a shoulder band connected to the head side main frame. With the lower body fixed with the leg band, the leg band is towed by a tow rope on which a weight is suspended. As a result, the traction force (extension force) according to the weight of the weight
Is attached to the leg band via a tow rope and serves to tow and extend the entire body from the leg side.

[0005]

However, the above-mentioned apparatus has a structure in which a weight having a required weight is suspended from a tip of a tow rope.
The leg band is pulled by the weight, and once started to be used, a user in a supine position cannot easily change the weight of the weight. Also, if for some reason it becomes necessary to stop the suspension,
It is difficult to instantaneously remove the load due to the weight. If the user himself does this, he must first raise himself and then add or reduce the weight, or disconnect the leg band from the tow rope. When asking the other person to do the work, the user does not need to wake up, but the assistant is not always nearby.

SUMMARY OF THE INVENTION An object of the present invention is to provide a novel traction extender which solves the above-mentioned disadvantages of the conventional traction extender in which the whole body is extended from the leg side by traction by the weight. To provide, and more specifically,
The traction force can be changed easily and practically steplessly while the body is lying down, and if for some reason it becomes necessary to eliminate the traction load, the user must It is an object of the present invention to provide a new traction stretcher that enables the user to do it instantaneously with the body lying down.

[0007]

According to the present invention, there is provided a traction extender, comprising: a base on which a user can lie; and one end of the base which slides in a longitudinal direction of the base. A leg retainer attached in a free manner, a belt retractor interposed with a one-way clutch attached to a base, and a belt interposed between the leg retainer and the belt retractor. And the leg holding device is moved rearward in the longitudinal direction of the base by the belt being wound by the belt winding device.

In the traction stretcher according to the invention, the user
Fix the ankle to the leg holder while standing on the base.
The leg holder is attached so as to be slidable in the longitudinal direction of the base, and the fixing operation of the ankle is easy. After fixing,
The user lies on the base, operates the belt winding device by hand, and gradually winds the belt. The belt rewinding device has a one-way clutch inside, and the rewinding can be easily performed only by reciprocating the handle.

When the belt is entangled, the leg holder gradually moves rearward in the longitudinal direction of the base, and a traction force corresponding to the amount of entanglement is applied to the leg of the user. The magnitude of the traction depends on the magnitude of the entanglement, and the user can easily set any traction with his or her own will. Also, when releasing the traction force, the user only has to operate the release lever or the like to operate the one-way clutch in the "disengaged" state, and this operation can be performed at any time and easily in a lying state. Can be.

[0010] In a preferred embodiment, the traction extender according to the present invention further includes an upper body holding device for stably holding the upper body side of the user with respect to the base. In this case, the stretching action by the traction is more effectively applied to the body. In a preferred embodiment, the base is entirely inclined so that the end provided with the leg holder is higher than the other ends. In this case, since the holding of the upper body with respect to the base can be further stabilized, it becomes possible to more effectively apply the stretching action by traction to the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a traction extender according to the present invention will be described below with reference to the drawings.
In the illustrated example, the base 10 has a hollow support 11 extending in the longitudinal direction, and an inverted T-shaped leg 12 fixed to the hollow support 11 by any means. The heights of the legs 12 may all be the same, but in this example, the hollow columns 1
1 so that the whole is inclined at a predetermined angle in a state of rising to the right in the figure,
They have different lengths. Further, the hollow support 11 may be an integral body, or may be a plug-in type that connects two members. In the latter case, there is an advantage that the storage when not in use is made compact. Further, the material of the hollow support 11 and the legs 12 is preferably made of steel, but may be made of fiber reinforced plastic or the like on the assumption that the hollow pillar 11 and the leg 12 have a required strength.

A horizontal plate 13 is integrally attached to the upper surface of the hollow support 11 at a predetermined interval by welding or the like, and a bench 14 is mounted thereon. The bench 14 may be a single piece, or may be divided into two as shown. In the latter case, there is an advantage that the storage when not in use is made compact. One end side (right end in the illustrated example) of the hollow support 11 is an upright standing portion 15, and the upright portion 1
A guide rod 16 is attached to 5 at a predetermined distance from the hollow support 11 and in a posture parallel to the hollow support 11. Reference numeral 20 denotes a leg holder supporting base slidably attached to the guide rod 16, and includes a base 21, a rising part 22, and an upper horizontal part 23 fitted to the guide rod 16. Substrates 24, 25 (only one of the substrates 24 is shown) are integrally attached to the lower surface on both sides of the base 20, and two parallel guide rods 2 are attached to the substrates 24, 25.
6, 26 are inserted. To the two parallel guide rods 26, a pair of left and right lower ankle fixing members 27 having a substantially U-shaped cross section are mounted so as to be position-adjustable in the lateral direction. The lower ankle fixtures 27, 27 are coated on the inner surface side with a soft material (for example, a material such as a urethane foam sheet).

The upper horizontal portion 2 of the leg holder supporting base 20
A vertical support 28 is inserted through the vertical support 3 so as to be movable up and down. The vertical support 28 can be fixed by a set screw 29 attached to the rising portion 22. Vertical support 28
Two parallel guide rods 36, 36 are inserted through the lower end of the upper ankle fixing device 37, which is a pair of left and right, substantially U-shaped cross sections. , 37
However, it is attached so that the position can be adjusted in the lateral direction (for simplicity of illustration, one (right side) upper ankle fixing device 37 is omitted in FIG. 1). The inner surfaces of the upper ankle fixing devices 37 are also covered with a soft material.

Further, a resistance tube 31 is fixed to the upright portion 15 of the hollow column 11 at a position substantially equal to the height of the guide rod 16, and the periphery of the resistance tube 31 is made of urethane foam. It is covered with a soft material.

The substrate 2 provided on the leg holder supporting base 20
Two parallel guide rods 26 inserted through 4, 25,
One end of a belt 40 is wrapped around and fixed to a portion of the substrate 26 between the substrates 24 and 25, and the belt 40 is fixed to guides 41 and 41 provided on the upright portion 15.
, The hollow portion of the hollow support 11 extends forward (from right to left in the figure).

At a substantially central position in the longitudinal direction of the hollow support 11, a support frame 50 having an inverted U-shape in a direction perpendicular to the hollow support 11 is attached. The support frame 50 is used for winding the belt 40. The winding rod 51 used is rotatably supported. The other end of the belt 40 is fixed to the winding rod 51. One end of the winding rod 51 extends laterally beyond one side wall 52 of the support frame 50, and its end reaches a position beyond the side edge of the bench 14. Sidewall 52
Is a horizontal portion 53 bent laterally, and the horizontal portion 5
A belt take-up device 60 having a one-way clutch mechanism 61 (not shown in detail) of a type having a conventionally known ratchet and ratchet pawls is attached to the belt 3. Thus, when the handle 62 as the operating rod of the belt winder 60 is rotated in the direction of arrow A in FIG. 2 (FIG. 2), the ratchet pawl is drivingly engaged with the ratchet, and the one-way clutch is engaged. And the winding rod 51 is driven to rotate, and the belt 40 is wound around the winding rod 51 by an amount corresponding to the rotation amount of the handle 62. On the other hand, when the handle 62 is turned in the opposite direction (turned in the direction of arrow B in FIG. 2), the ratchet pawl returns on the ratchet in a non-engaged state, while the winding rod 51 is placed in a non-rotated state. Therefore, the user can reciprocate the handle 62 an arbitrary number of times to thereby make the belt 4 an arbitrary amount.
By winding 0, the upper and lower ankle fixtures 27 and 37 slide on the guide rod 16 in the right direction in the figure according to the amount of the roll.

The belt winding device 60 includes a handle 62.
, That is, a position where the fingertip thereof can be easily reached when the user is holding the handle 62, and pulls the release lever 63 toward the user. Thus, the engagement of the one-way clutch 61 (in this case, the engagement of the ratchet claw with the ratchet) is instantaneously released.
When the engagement is released, the winding rod 51 can freely rotate, and as a result, the leg holder supporting base 20 can freely slide on the guide rod 16.

Next, a method of using the traction extender will be described. The user rides on the bench 14 and uses the belt retractor 60.
The one-way clutch 61 is disengaged ("disconnected").
The leg holder supporting base 20 is pulled forward along the guide rod 16, the width of the upper and lower ankle fixing members 27 and 37 is adjusted as necessary, the set screw 29 is loosened, and the upper ankle fixing member 37 is raised. . After placing the ankle portion on the lower ankle fixing device 27, the upper ankle fixing device 37 is lowered, the ankle portion is clamped by the upper and lower ankle fixing devices 27 and 37, and the set screw 29 is tightened.

In this state, the user lies on the bench 14 (see FIG. 3) and grasps the tip of the handle 62 of the belt winder 60 with one hand (the right hand in the case shown).
The pulling toward the front (in the direction of arrow A in the figure) and the return (in the direction of arrow B in the figure) are repeated. Thereby, gradually the belt 40
Is wound around the winding rod 51, and the leg holder supporting base 20 moves rearward along the guide rod 16 accordingly. By this movement, the user's ankle portion is gradually pulled and extended rearward while being held between the upper and lower ankle fixing devices 27 and 37. Belt 4 with handle 62
The entanglement of 0 is continuously performed, and the entanglement is stopped when the user himself / herself feels that the traction is appropriate or when the toe contacts the resistance tube 31 described above. In this example, the legs 12 have different lengths so that the entire hollow column 11 is inclined at a predetermined angle in a state of rising to the right in the figure, so that the ankle fixing devices 27 and 37 are used to extend and retract the ankle portion rearward. The whole body is not dragged back.

After the state is continued for a predetermined time, the user pulls the release lever 63 toward the user to release the towed state, and releases the ankle portion from being clamped by the upper and lower ankle fixtures 27 and 37. If for some reason it is necessary to stop the traction and extension backward during the winding, the user can achieve the purpose only by pulling the release lever 63 forward, which is extremely safe.

4 to 9 show another embodiment of the traction stretcher according to the present invention. The traction extender of this embodiment further includes an upper body holding device for stably holding the upper body side of the user with respect to the base 10.
After lying on the upper body 4, the upper body holding device stably fixes the upper body of the user, whereby the rearward traction and extension by the upper and lower ankle fixing devices 27 and 37 can be reliably applied to the entire body. Further, by interposing a spring (spring), the body can be protected from excessive traction.

In the example shown in FIG. 4 and FIG.
Numeral 0 denotes an annular body 103 attached to the left and right ends of a mounting body 101 having a width approximately equal to the shoulder width via springs 102. A vertical rod 104 mounted at the center of the mounting body 101 is a hollow support. 11 to be attached to the main body side. In use, as shown in FIG. 5, an arm is passed through the annular belt 103, and the upper body of the user is held by the armpits. Thereby, the upper and lower ankle fixtures 27, 37
Even if it is pulled backward by, it is possible to reliably prevent the whole body from being dragged in that direction,
Traction extension can be reliably exerted on the whole body.

In the example shown in FIGS. 6 and 7, the upper body holder 2
00 has a U-shaped gripping rod 201 having a width approximately equal to the shoulder width, and a vertical rod 202 attached to the center of the U-shaped gripping rod. Attach it so that it protrudes upward. 204
Is a receiving member for slidably attaching the vertical rod 202 to the hollow support 11. When using the upper body holder 200, as shown in FIG. 7, the U-shaped part is inserted into the armpit of the user. Again, in this case,
Even if the upper and lower ankle fixtures 27 and 37 are pulled and stretched rearward, the U-shaped portion can reliably prevent the entire body from being dragged in that direction. Also in this case, the attachment position of the upper body holder 200 to the hollow column 11 can be adjusted in the vertical direction by appropriate means, so that the difference in usage due to the difference in height can be easily adjusted. It is.

FIGS. 8 and 9 show modifications of the upper body holder 100 shown in FIGS. 4 and 5. In each case, in addition to the annular belts 103, 103, the annular belt 1 is provided.
A second belt 103a for stabilizing the posture of the body 03, 103 with respect to the body is provided. In use, the arm is passed through the annular belt 103, and then the second belt 103a is tightened, so that the traction and extension can be performed in a more stable posture. Further, an elastic pad 104 is attached to a portion where the annular belt 103 is in contact with the armpit to enhance the usability. Further, the annular belt 103
The buckle 105 has a length adjustable by a buckle 105, so that a difference in usage due to a difference in height can be easily adjusted.

In the example shown in FIG. 8, the spring 102 is attached to the attachment body 101 so as to generate elasticity by being compressed when subjected to traction and elongation, and the holding of the body is further stabilized. In the example shown in FIG. 9, the spring 102 is arranged not in the traction direction but in a direction perpendicular to the traction direction, and the attachment body 101 and the annular belt 103 are attached to the attachment body 1.
01 is connected via a link 106 pivotally supported at one end, and a moment in the direction opposite to the traction direction is generated on the link 106 by traction and extension.
Thereby, a required effect can be obtained with a compact configuration.

Although not particularly shown, the entire upper body holder 100 or 200 is attached to the base 10 by appropriate means (for example, a pin such as a tome pin is inserted into one of a plurality of mounting holes formed on the base side). Means for attaching the body of the upper body holder, etc.), it is possible to adjust the mounting position in the length direction in multiple steps, thereby providing a more appropriate position for users with different elongations. It becomes possible to set the upper body holding device on the body. Further, it is also effective to always urge the leg holder supporting base 20 toward the side where the user's head is located along the guide rod 16 by an appropriate spring means. In this case, when the user releases the one-way clutch and sets the leg holder supporting base 20 in a free state, the leg holder supporting base 20 automatically returns to the uppermost position of the guide rod 16. And the next use becomes easy.

[0027]

According to the traction extender of the present invention, the user can change the traction force easily and substantially steplessly while the body is lying on the bench, and the traction device can be used for any reason. If it becomes necessary to release the extension, the user can do so instantly. Thereby, health promotion by traction and extension according to individual differences can be surely promoted, and safety is also ensured. Further, by using the upper body holding device, the traction and extension can be reliably applied to the entire body, and the danger due to excessive traction can be prevented.
