DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to improvement of a tilt table used for prevention of various troubles such as a decrease in standing sensation and recovery of functions, which occur in a long-term bed rest patient.

2. Description of the Related Art In the tilt table of the related art, a foot rest is provided at a lower end portion of a table portion on which a patient is placed, and a tilt drive portion is provided at a base portion that supports the table portion. By operating the tilt drive unit, the table unit is rotated in a direction in which the footrest is positioned downward, tilted at an arbitrary tilt angle, and stopped for an appropriate time for standing training or the like.

When returning the tilted table part to the original horizontal position, the tilt drive part is operated after confirming that there is no object, such as a person or an article, that obstructs the rotation within the range of the turning radius of the table part.

Problems to be Solved by the Invention In the conventional tilt table, when the table part in the vertical state is returned to the horizontal state, when the caregiver inadvertently operates the table part in the horizontal state by an inadvertent switch operation, or it is automated. When the treatment time set on the tilt table elapses and the table automatically turns to the horizontal state, if there is an obstacle, that is, a person or article within the turning radius of the table, tilt backward. There is a problem in that the rotating table portion strongly collides with a person or an article, injuring the person or damaging the article.

Further, when such a dangerous accident occurs, the patient is anxious or surprised, and the mental state of the patient is adversely affected.

Therefore, it has been desired to provide a safety device such as an automatic stop device for preventing such a dangerous accident or a guide device for guiding the rotation direction immediately before the tilt table rotates.

Means for Solving the Problems The present invention solves the drawbacks of the prior art, and when a person or article exists within the range of the turning radius of the table part, without causing injury or damage to the person or article. , The purpose is to provide a self-stop table that can ensure safety and take precautionary measures to enhance safety.

That is, according to the present invention, the tilt table includes a sensor 8 provided at an appropriate position of the tilt table for detecting an object existing within the range of the turning radius of the table portion 1, and a tilt drive portion 5 for tilting and turning the table portion 1. When the sensor 8 detects an object, the operation of the tilt drive unit 5 is stopped and the table unit 1
It is an automatic stop type tilt table characterized in that the tilt rotation of the horizontal table is stopped.

Further, the tilt table is provided at an appropriate position on the tilt table, a sensor 8 for detecting an object existing within the range of the turning radius of the table portion 1, a tilt drive portion 5 for tilting and turning the table portion 1, and a warning. And a warning signal generator 18 for generating a warning signal, and when the sensor 8 detects an object, the operation of the tilt drive unit 5 is stopped, the tilt rotation of the table unit 1 in the horizontal direction is stopped, and a warning signal is generated.

Rotate until tilted.

The table portion 1 is stopped in a tilted state or a vertical state and stopped for a predetermined time required for treatment.

When the predetermined treatment time elapses, the treatment timer 15 automatically operates the tilt drive unit 5 to return the upper plane of the table 1 to the horizontal position from the predetermined tilt angle.

When the table unit 1 returns to the horizontal position, that is, when the table unit 1 is in the backward tilting rotation, if an obstacle exists within the range of the turning radius of the table unit 1, the sensor 8 is activated by the presence of the obstacle,
When the sensor 8 operates, the warning sound generator 18 operates to generate a warning sound, and the operation of the tilt drive unit 5 is immediately stopped.

Effect of the Invention The present invention has a structure in which a sensor is provided on the tilt table, and when the sensor detects an object and operates, the tilt drive section is operated by the output of the sensor and the rotation of the table section is stopped. In a specific example where the sensor is a sheet-like sheet switch, a sheet-like sensor is attached to the upper half of the back of the table with a cushioning material interposed, and the sensor conducts while the table is rotated backward. Then, the electrical structure is provided to stop the rotation of the table portion.

At the time of finishing the treatment performed by inclining the table part, when returning the table part to the original horizontal state, if there is an obstacle within the range of the turning radius of the table part, the table part will be tilted backward. Even if an obstacle comes into contact with the sensor, the sensor works by the contact pressure and the tilting movement of the table portion is immediately stopped.

Therefore, in a function recovery training room or the like where an unspecified person is present around the present invention, even if the table section hits the unspecified person, the shock absorbing material is absorbed by the cushioning material, and the table section slightly touches the sensor. Since it stops by contact pressure, it is safe without causing injury, and even if the table part hits the article, it is not damaged, and the caregiver can use the device of the present invention with peace of mind.

When an ultrasonic proximity switch or magnetic sensor, which is another specific example of a sensor, is used, both of these ultrasonic proximity switches and magnetic sensors can detect obstacles in a non-contact manner. This has the advantage that the zone settings for the distance can be adjusted. Also, when using an actuator type sensor, the structure is simple, the distance between the contact plate and the table can be easily changed and adjusted, and when the table comes into contact with an object, the timing of pre-stop can be optimally adjusted for safety. Can be increased.

Further, as in the present invention, in which the horizontal switch is interlocked with the treatment timer and the table portion is automatically rotated and returned to the horizontal position when the set treatment time elapses, the automatic stop by the sensor is configured. It is extremely useful to install the to ensure safety. Since this automatic stop structure is attached to the tilt table, the present invention can be used with peace of mind, and the labor can be saved.

In addition, by providing a warning signal generator that generates a warning sound when the output of the sensor is given, if there is an obstacle within the range of the turning radius of the table part, the caregiver is quickly notified and the tilt table This has the effect of ensuring the safety of the surrounding people more quickly.

Further, since the guide signal generator for guiding the rotation direction of the table portion 1 when the tilt drive portion is operated is provided, each of the rotation of the standing rotation of the table portion or the backward rotation of the table portion can be performed. Occasionally, a voice for standing up or a voice for tilting backward is displayed, giving the patient a mental feeling for the pivoting of the table and giving a sense of security, and being around the tilt table. There is an effect that it is possible to encourage people to prevent danger, further safely use the device, and improve reliability.
