Description

[Detailed description of the invention] Industrial application field This invention relates to improvement of exercise equipment for rehabilitation.

Conventional technology Conventionally, exercise equipment for rehabilitation is
In some cases, the hands and feet are hung on a holder connected to a spring or weight, and the holder is moved up and down to increase the strength of the limbs by only moving the limbs up and down. Or, it is known that parallel bars of the same height are provided and walking training is performed by holding onto the parallel bars. However, these devices only have a single function, such as for vertical movement of the limbs and for walking training, and therefore, in order to perform various exercises and training, it is necessary to prepare a large number of exercise equipment corresponding to them. It was hot.

Problems to be solved by this invention The purpose of this invention is to solve the above-mentioned problems of conventional rehabilitation exercise equipment, and to make it possible to perform complex three-dimensional movements such as up and down, rotation, and back and forth movement of the limbs. An object of the present invention is to provide exercise equipment for rehabilitation.

Means for Solving the Problems In order to achieve the above object, the rehabilitation exercise device of this invention has a first arm that swings up and down via a spring, which is attached to a fixture so that it can rotate freely in the horizontal direction. The second arm is horizontally rotatably connected to the first arm, the second arm is extendable and retractable in the axial direction, and a holder is attached to the tip of the second arm.

Embodiments Hereinafter, embodiments of this invention will be described based on the drawings.

The figure is a sectional view of a main part of an embodiment of this invention. Reference numeral 1 designates a first arm, and one end to which the balance cam 2 is fixed is attached to the spring case 3 so as to be vertically swingable about a shaft 12, and the lower end of the coil spring 4 provided in the spring case 3 A portion of the balance cam 2 is connected by a wire 5, and the first arm 1 is vertically swingable via a coil spring 4. The upper end of the coil spring 4 is connected to the lower end of a load adjustment bolt 6 provided at the upper end of the spring case 3, and the coil is adjusted by the rotation of a female threaded body 23 that is screwed into the bolt 5 rotatably provided at the upper end of the spring case 3. The upper end of the spring 4 is designed to move up and down. Reference numeral 7 denotes a pulley, around which the wire 5 is wound, and is provided within the spring case 3 to allow the wire 5 to move smoothly.

Further, the lower part of the spring case 3 is inserted into a fixture made of a fixed tube 8 so as to be freely rotatable in the horizontal direction.
It is fixed to the fixed cylinder 8 by a tightening screw 9 attached to the fixed cylinder 8. This fixed cylinder 8 is provided with a tightening body 11 for attaching it to a table 10 or the like. That is, the first arm 1 is provided horizontally rotatably with respect to the fixed cylinder 8.

By the way, as shown in the figure, when the tip of the first arm 1 is upward and the coil spring 4 is contracted, the balance cam 2 supports the wire 5 at a fulcrum that is farther from the rotating shaft 12, and The tip of the arm 1 is shaped so that as it goes down, it is supported by a fulcrum that approaches the rotating shaft 12, so that the force of the coil spring 4 that balances the force of the tip of the first arm 1 going down is always constant. It is formed.

The tip of the first arm 1 is a support tube 1 facing in the vertical direction.
arm 1 attached to 3 and parallel to the first arm 1;
4 is rotatably attached to the spring case 3 and the support tube 13. The first arm 1, the parallel arm 14, the spring case 3 and the support tube 13
to form a parallel link so that the support cylinder 13 is always moved while maintaining the vertical direction, and the attachment part between the spring case 3 of the parallel arm 14 and the support cylinder 13 has a height of flight of the support cylinder 13 when rising and falling. Stoppers 15 and 16 are attached to determine the distance.

A cylindrical balance weight 17 is detachably provided at the upper end of the support tube 13, and one end of a second arm 18 is attached to the lower end so as to be horizontally rotatable. It can be rotated in the horizontal direction. The second arm 18 has a sliding arm 19 that slides inside, and is extendable and retractable in the axial direction, and the sliding arm 19 is fixed in that position by a set screw 20 provided on the second arm 18. . A holder attachment piece 23 is attached to the tip of the sliding arm 19 so as to be horizontally rotatable, and the holder attachment piece 23 is provided with a hole into which the holder longitudinal adjustment rod 21 is slidably inserted. Further, a set screw 24 is provided to hold the holder longitudinal adjustment rod 21 in that position. Then, a first holder 22a and a second holder 22b are attached to each of the holder front and rear adjustment rods 21, and the second arm 18
Holders 22a and 22b are attached to the tips of the holder.

The above-described embodiment of this invention having the above-described configuration operates as follows. In other words, for example, when performing strength-increasing exercises by moving your arms and legs up and down,
Spring case 3 is tightened by tightening screw 9 of fixed cylinder 8.
is fixed to the fixed cylinder 8, and then the stoppers 15 and 16 of the parallel arm 14 are loosened, and the internal threaded body 23 is rotated to move the load adjustment bolt 5 up and down to adjust the strength of the coil spring 4. Therefore, the first holder 2
By inserting both hands or both feet into the second holder 2a and the second holder 22b and moving the holders 22a and 22b up and down, the tension of the coil spring 4 is applied to the balance cam 21.
It acts as a constant load through the machine, and you can always move both hands or feet up and down with a constant force, allowing you to train to increase the strength of your hands or feet.

Also, if the hands or feet inserted into the holders 22a and 22b are moved left and right, the second arm 18 can be moved to the support tube 1.
3, it is possible to move the hand from side to side. Furthermore, when the screw 20 of the second arm 18 is loosened, the sliding arm 19 slides inside the second arm 18, so the hand or foot can be moved back and forth. Able to perform complex movements from side to side.

Furthermore, if the spring case 3 is made rotatable with respect to the fixed cylinder 8 by loosening the tightening screw 9, the spring case 3 will rotate horizontally with respect to the fixed cylinder 8, and will follow even more complicated movements. can do. In addition, this embodiment is a rehabilitation exercise device that can be used for various exercises, such as training to increase the strength of abdominal muscles and back muscles.

Effects of the invention As is clear from the above, the rehabilitation exercise device of this invention has a first arm that swings vertically via a spring attached to a fixture so as to be horizontally rotatable. The two arms are horizontally rotatably connected, the second arm is extendable in the axial direction, and a holder is attached to the tip of the second arm, so the holder can move up and down and double horizontally. It can perform circular arc movements and horizontal rectilinear movements, and can handle extremely complex movements compared to conventional ones that only have a single function. It has the excellent effect of being able to perform various kinds of rehabilitation exercises such as rotational exercise, and having a simple structure and easy handling.
