Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a tilt table for standing training in which a table for holding a trainee in a lying position with a belt can be tilted between a horizontal position and a standing position.

A tilt table for standing up training, which is configured to tilt a table for a trainee to lie down between a horizontal state and an upright state, is known as seen in Japanese Patent Publication No. 56-6291; The tilt table for trainees is configured such that the table for lying down on a trainee can be in a horizontal state only at one predetermined height position set in advance at the stroke end.

Therefore, if the horizontal height of the table is set to match the height of a normal medical bed, it will be easy for the trainee to transfer from the medical bed to the table or from the table to the medical bed. However, when transferring a trainee who is at a different height from the treatment bed (for example, a wheelchair), there will be a step between the table and the wheelchair, so it is difficult to transfer the trainee easily. There is a drawback that it cannot be done. Furthermore, if the height at which the table becomes horizontal is set to match the height of the wheelchair, contrary to the above, it will become difficult to transfer the trainee from the treatment bed; Since the height of the horizontal table is extremely low, it is difficult for the caregiver (trainer) to fix or unfix the trainee's body to the table.
When performing functional training exercises, the patient must bend his or her hips in an unnatural posture, making it difficult to perform assistance or training tasks.

Therefore, the present invention was carried out for the purpose of providing a tilt table for standing training with a new configuration that can solve all of the above-mentioned problems that conventional tilt tables for standing training had. The drive support part on the underframe is oscillated by the rotation of a drive gear that performs a predetermined operation by an appropriate drive mechanism, a large gear and a small gear that mesh with the drive gear, and the large gear. Consisting of a long arm and a short arm that swings by the rotation of a small gear, the table for the trainee to lie down can be maintained in a horizontal position at a low position by the other end of each of the long arm and short arm. The table is supported as shown in FIG.
After that, the device is characterized in that it is configured to gradually tilt and change its posture to an upright position.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

One end of each of the operating levers 12, 12 is fitted and fixed to the intermediate portion in the length direction of the drive shaft 10, and each of the other end sides of the operating levers 12, 12 has an operating shaft parallel to the drive shaft 10. A piston 13 in a drive mechanism C is pivotally connected to the operating shaft 24, and the swinging of the operating lever 12 due to the expansion and contraction of the piston 13 moves the drive gears 1, 1 to a predetermined position. Can be rotated forward and reverse within the angle range, and
By fixing the piston 13, the drive gear 1 can be held fixed at any operating position within a predetermined range.

The drive mechanism C includes a hydraulic cylinder 14 having the piston 13, a motor 16 controlled by an operating section 15, and a hydraulic pump 17 connected to the rotating shaft of the motor 16 and having a built-in appropriate electromagnetic valve (not shown).
It is configured to be operated by.

Drive shaft 10 in the brackets 9, 9 described above
A rotary shaft 18 parallel to the drive shaft 10 is horizontally supported in a portion above the shaft support, and at both ends of the rotary shaft 18 there are small gears 3, 3 that mesh with the drive gears 1, 1, respectively. It is fitted and fixed.

Also, one bracket 9 and the other bracket 9
Another bracket 19, 19 is provided upright on the lateral side of both brackets 9, 9 on a parallel line connecting the two brackets 9, 9. A rotating shaft 20 is horizontally supported, and large gears 2, 2 meshing with the drive gears 1, 1 are fitted and fixed to both ends of the rotating shaft 20.

Note that drive gears 1, 1, large gears 2, 2, and small gears 3, 3 are, for example, large gears 2, 2 have 3/2T teeth, and small The number of teeth of the gears 3, 3 is configured to have a tooth ratio of 3/10T, and the drive gears 1, 1 are driven by the piston 13.
When the gear rotates about 148 degrees, the large gears 2 and 2 rotate about 99 degrees, and the small gears 3 and 3 rotate about 495 degrees.

Thus, cranks 5, 5 that rotate together with the respective small gears 3, 3 are attached to the outer parts of the small gears 3, 3, and one ends of short arms 6, 6 are attached to the tips of the cranks 5, 5, respectively. Long arms 4, 4 are attached to the large gears 2, 2 and swing by the rotation of the large gears 2, 2 about the axis of the rotating shaft 20.
is installed.

The other ends of the short arms 6, 6 of the drive support part B configured as described above are aligned with the horizontal axis of the back side of the footrest 21 side provided at the end of the table 7 for the trainee to lie down. 22 is pivotally connected to both ends,
The other ends of the long arms 4, 4 are connected to short arms 6, 6.
The table 7 is held by being pivotally connected to both ends of the horizontal shaft 23 on the back surface of the table 7 at a portion appropriately spaced apart from the pivot joint. When the long arms 4, 4 and the short arms 6, 6 are at one stroke end, the table 7 is maintained in a horizontal state (including a substantially horizontal state) at the lowest possible position, and the long arms 4, 4 , short arm 6,6
When the table 7 swings toward the other stroke end, the table 7 is moved upward while remaining horizontal within a predetermined range L, and then the footrest 2 is gradually moved up.

In addition, 7a, 7b, 7c, 7d in FIG.
1A and 2B respectively show the operating stages of the table 7 for the trainee lying down: a low horizontal state, a high horizontal state, a tilted state, and an upright state.

Next, the operation of the tilt table for standing training having the above configuration will be explained.

When performing training, the tilt table for standing training is moved to a location necessary for training, and fixed in place so that the frame A does not move or cause any danger while the patient is being transferred.

Then, the motor 16 and the hydraulic pump 17 are operated by operating the operation unit 15, the hydraulic cylinder 14 is operated, the table 7 is operated to be in the low horizontal state of the table 7a as shown in FIG. By stopping the operation of the hydraulic cylinder 14, the hydraulic cylinder 14 is stopped and fixed, and the drive gears 1, 1 interlocked with the hydraulic cylinder 14 and the large gears 2, 2 and small gears 3, 3 that mesh with these are fixed. The arms 4, 4 and the short arms 6, 6 are also fixed, and the table 7 is maintained and fixed to a table 7a in a horizontal position as low as possible.

Therefore, the table 7a in the low horizontal state
The trainee who is at the same height as the table 7a can easily transfer onto the table 7a.

After the trainee has been placed on the table 7a, the piston 13 of the hydraulic cylinder 14 is extended while controlling the operation part 15, and the drive gears 1, 1 are moved in the direction indicated by the arrow. Since the large gears 2, 2 and small gears 3, 3 that mesh with the drive gears 1, 1 also rotate in the desired direction,
The long arms 4, 4, and the short arms 6, 6, which swing by the rotation of the large gears 2, 2 and the small gears 3, 3, are connected to the table 7.
While remaining in a horizontal state, it is moved in parallel over a predetermined range L and raised.

Therefore, the predetermined range L in which the table 7 moves in parallel
When the desired height position is reached between the two, if the operation of the hydraulic cylinder 14 is stopped using the operation unit 15, the table 7 can be fixed and held in a horizontal state at the desired height position. After fixing the table 7 at a suitable height, the trainee can perform fixed and training movements on the table 7, and the caregiver can easily perform the assistance work without having to take an unreasonable posture. It is possible to carry out training and training work.

Furthermore, the table 7 on which the trainee was fixed in a lying position was
When it is necessary to tilt or stand up, the piston 13 of the hydraulic cylinder 14 is further extended so that the table 7 is tilted beyond the predetermined range L of parallel movement. The drive support part B, which is composed of three groups of small gears and a long arm 4 and a short arm 6, gradually tilts the table 7 like the table 7c in the tilted state in FIG. Since the table 7 is raised up like the table 7d in the upright position in Figure 1, the table 7 can be easily changed to a tilted position or a standing position, and the table 7 can be returned from the standing position to a low horizontal position. The movement is carried out by the hydraulic cylinder 14.
This can be easily done by retracting the piston 13. In this way, a series of standing training movements are performed by simply extending or retracting the hydraulic cylinder 14, so the device is easy to operate, and the caregiver can easily and safely raise and lower the table 7, or raise and lower it. It can be implemented.

As described above in detail with reference to the embodiments, the effects of the present invention are such that the table for lying down on the trainee is placed in a horizontal position at the lowest possible position, and the table for the trainee remains in a horizontal position within a predetermined range. The table driving support is structured so that it moves up and then gradually tilts to change to a standing position, so even if the trainee's height differs, the trainee's The height of the table can be made to match the height of the table while remaining horizontal, and the assistant can always easily and safely transfer the trainee from one table to another, and from one table to another.

In addition, since the table remains horizontal and can be changed and maintained at a convenient height for the caregiver to perform various movements, assistance and training tasks can be performed more easily than with conventional devices.

Furthermore, the height of the table can be adjusted while maintaining it horizontally within a predetermined range, thereby achieving the above-mentioned convenience, and the simple structure of controlling a hydraulic pump and driving a motor. With simple operation, the table can be placed in a tilted position.
It has the advantage that it is extremely easy to use because it can be changed to an upright position, and the manufacturing cost is low.
