The footrest 32 configured as described above is detachably attached to the rope 5.

Next, the installation state and the use state of the exercise equipment 1 described above will be described. At the time of installation, first, left and right side supports 7 are attached to both ends of the frame main body 6, respectively. That is, the sliding rod 17 is
The sliding rods 18 are respectively inserted into the support cylinders 11 to form the U-shaped frame portion 2 in plan view as shown in FIG. After adjusting the distance between the left and right side supports 7 and 7 so as to be slightly wider than the width of the bed, the total of four thumb screws 15 are tightened, and the frame body 6 and the side supports 7 are tightened. , 7
And fix.

A column 3 is attached to the frame 2. Here, the outer cylinder 24 of the column 3 is
In a state fitted in the gap 12 between the support cylinders 10 and 10 and the gap 13 between the support cylinders 11, 11, a locking tool 28 is hooked on the upper side 8 a of the peripheral frame 8, and a hooking tool 29 is hooked on the lower side 8 b. To stop. As a result, the outer cylinder 24 is sandwiched between the opposed inner ends of the support cylinders 10 and 11, and the column 3 is held upright.

Then, one end in the longitudinal direction of the bed (head mounting side in this case) is slightly lifted, and the left and right legs on this side are mounted on the left and right mounting portions 22, respectively. Hereinafter, this installation state will be described with reference to FIG. In FIG.
Reference numeral 50 denotes a bed, 51 denotes a bed frame, 52
Indicates a mattress, 53 indicates a leg on the head mounting side, 54 indicates a leg on the lower limb mounting side, and 55 indicates a floor surface of a room where the bed 50 is placed. In this installation state, exercise equipment 1
Of the bed 50 is disposed close to the head placement side of the bed 50, and the frame body 6 extends in the width direction of the bed 50. The leg 53 on the head placement side of the bed 50 is placed on the placement portion 22 extending inward from the side support 7. FIG. 8 shows a state on the right side from the bed 50 toward the exercise equipment 1, but the left side is also the same.
The legs 53 are pressed down from above, so that they are not easily moved or fall down, and are firmly installed.

The height of the column 3 is adjusted appropriately before or after the installation of the exercise equipment 1 according to the height of the bed 50 and the height of the user, and the thumb screw 27 is tightened. Fix to height. Further, the rope 5 is inserted into the insertion portion 4a (see FIG. 6B) of the pulley 4 in a state where one of the footrests 32 (the portion beyond the snap fitting 35) is removed, and then The attached footrest 32 is attached in advance.

When using the exercise equipment 1 installed as described above, first, both feet of the user are hooked on the footrests 32, respectively. Here, as shown in FIG. 9, after putting the heel into the footrest ring 33 from the sole side of the foot, the bands 36a, 36b
Is turned toward the instep of the foot, and the hook-and-loop fasteners 37a and 37b are engaged with each other to connect the bands 36a and 36b. Then, the finger hooking member 39 is sandwiched between the toe and the forefinger.

In the state where both feet are hooked on the footrests 32, the user lies on the mattress 52 of the bed 50 as shown in FIG. 8 and alternately raises and lowers both feet while stretching the knee joint as much as possible. At this time, as shown by an arrow in FIG. 8, as one of the raised legs is lowered, the rope 5 moves in the direction of the arrow, whereby the other leg is pulled up. Therefore, even when the user's leg is weak, the leg can be easily moved up and down between a substantially horizontal position and a substantially vertical position, thereby strengthening the leg and muscle strength,
Fatigue recovery, functional recovery, back pain prevention and treatment, etc. can be performed very suitably.

The exercise equipment 1 of this embodiment described above
According to the above, the following effects can be obtained. That is, for example, even when used by patients or elderly people who usually sleep on the bed, there is no need to move from the bed to the table of exercise equipment as in the case of using conventional exercise equipment, Exercise can be done while sleeping. Therefore, it is possible to start the exercise promptly and easily when the person wants to exercise without feeling any difficulty or pain for moving and without requiring the assistance of others. Very convenient. In addition, since the user exercises on the mattress of the bed, which is rich in cushioning properties, it is possible to prevent a burden on the waist and back during exercise.

Further, unlike the conventional exercise equipment, there is no table on which the user can lie supine, and the bed can be installed in an extremely small space at one end in the longitudinal direction of the bed. Since the bed can be used even in the installed state, it does not obstruct the use of the bed, so that there is no need to install or clear the exercise equipment each time the bed is used, and there is no burden on the user.

Further, since the distance between the side supports 7, 7 can be changed, the side supports 7 can be attached to various types of beds having different widths, and the columns 3 can be extended and contracted. By adjusting the height position of the pulley 4 in accordance with the height, the height of the user, and the like, the effect that exercise can always be performed in an optimal state can be achieved.

Further, the tension of the rope 5 is applied to the ankle during use. In this exercise tool 1, the cushion material 38 in the footrest portion 32 protects the heel, and the rope (connecting portion 34) is provided by the fingerholding member 39. Since the friction between the ankle and the finger is prevented, the user does not feel any pain, and since the ankle ring 33 and the ankle are fixed by the bands 36a and 36b, the ankle is removed from the ankle portion 32. Inconveniences such as accidental detachment can also be prevented.

Further, since the mounting portion 22 is pressed downward by the weight of the bed, even when the pulley 4 is pulled by the tension of the rope 5 during use, the frame portion 2 and the support column 3 are shaken. And a stable use state can be obtained.

Needless to say, the present invention is not limited to the above embodiment. For example, in the above description, the exercise equipment 1 is installed on the head mounting side of the bed, but the exercise equipment is installed on the lower leg mounting side of the bed. It does not matter. In the above description, the side supports 7, 7 are fixed to the frame main body 6 with the thumb screws 15, but the fixing means of the side supports is not limited thereto. A plurality of pin holes are formed at appropriate intervals in
Pin holes are also formed in 0 and 11 so that the support cylinders 10 and 11
A means such as inserting a pin inserted from the pin hole of any one of the sliding rods 17 and 18 into the pin hole can also be adopted.

In the above description, the mounting portion 22 is attached to each of the pair of side supports 7 with variable intervals. However, the configuration of the mounting portion is not limited thereto, and may be arbitrary. It is also conceivable that a plate-shaped member is extended in front (bed side), and the upper surface of the plate-shaped member is used as a mounting portion. In this case, the mounting portion does not necessarily have to be divided into right and left, and a configuration in which left and right legs of the bed are mounted on both ends of one mounting portion that is long in the width direction of the bed may be used.

Further, in the above description, the "pulley support" according to the present invention is constituted by the pillars 3. However, the pulley support is not necessarily a pillar. For example, the frame part is extended upward and the extended part is formed. It is also conceivable that the pulley is supported by the support member (that is, the frame portion and the pulley support portion are integrally formed).

Further, the configuration of the footrest is optional.
For example, a footrest as shown in FIG. 10 can be used. FIG. 10A is a perspective view of a footrest, and FIG. 10B is a perspective view illustrating a state in which the foot is hooked on the footrest. This footrest part 4
1 is provided with a footrest member 42 made of a flexible material such as leather, cloth, and soft synthetic resin, and a pair of connecting members 43 formed of metal or the like in an annular shape. The footrest member 42 has a pair of strips 45, 45 inclined perpendicularly to each other for hooking the sole of the foot and a portion slightly above the heel, and these strips 45, 45 have both ends. Connecting portions 46, 46 which are connected to each other at the
Are connected to each other. A hole 44 for allowing the heel to escape is formed between the belt portions 45. The connecting members 43 are provided at the upper ends of the connecting portions 46, 46, respectively.

The footrest portion 41 is attached to both ends of the rope 5 instead of the footrest portion 32 directly or via the same snap fitting 35 as described above. FIG. 10 (b) shows a state in which the foot is used by hanging the foot on the footrest portion 41. As is apparent from this figure, the pair of connecting tools 43, 43 are collectively connected to the rope 5. One band 45 is hung on the arch of the sole, and the other band 45 is hung slightly above the heel of the foot.
Then, the user puts both feet on the footrests 4 in this manner.
In the state of being hung on 1, the patient lays on the bed and performs an exercise of alternately raising and lowering both feet.

In the footrest 32, it was necessary to connect a pair of bands with hook-and-loop fasteners.
In such a case, there is no need to perform such a work, and the device can be used only by inserting an ankle into the inside of the footrest member 42 suspended in a U-shape at the end of the rope 5. Accordingly, it is possible to extremely easily engage and disengage the foot with the footrest portion, and to obtain an exercise device that can be easily used by the elderly and those who are physically disabled due to injuries or illness. In addition, since the tension of the rope 5 is applied to the ankle via the wide band portions 45, 45, the force is dispersed over a wide area, and a part of the foot does not hurt during use. Furthermore, since the heel is fitted in the hole 44 during use, the ankle does not accidentally come off the footrest 41.

[0037]

As described above, according to the exercise equipment for attaching a bed according to the present invention, since the exercise can be performed on the bed placed in the bedroom or the sickroom and the leg can be moved up and down, the patient can sleep on the bed. Various effects that cannot be obtained with the conventional exercise equipment, such as being able to be used as it is and being able to be installed in a narrow space, are exhibited.
