Since the swingable bend (with a stop mechanism) according to the embodiment of the present invention is constructed as described above, when it is divided, the load converter 69 etc. 9b
and separate it into an independent independent part IA.

Since it can be separated into the IB and the mounting part 1C, portability during movement is improved. During assembly 1': is the load converter 69 etc. part, the stretcher part 4 and the 7 run 79a,
It is possible to assemble them into one by combining them with 9 b. , insects, and easy maintenance.

After this assembly, the first and f\S2 support shafts 8a.

81] is supported by double bearings 7a and 7b, so each sentence! Misalignment of the swing axis in 1lI8a18b is allowed.

In addition, during rocking, the power switch Gla of the grinding machine 64 in the control system is
Start signal from 61b (61c) and direction switch 61b (61c
) The rocking is started in response to a rocking direction signal from the rotor 61, and the left and right rocking angles φ11φ2 during the rocking are changed according to the set values from the knobs 61e and 61f as manual switches.

In addition to the normal swing speed, high speed rotation can be selected based on the input from the high speed rotation switch 61d.

Further, as shown in FIGS. 8 to 10, when the pulse motor 23 is driven to rotate in one direction (forward rotation), the reduction tooth I'lI24
and the outer cylinder 22B is rotated via the universal joint 26,
The inner shaft 22A that meshes with the outer cylinder 22B moves up and down, and the arm 21 is swung.

Then, when the pulse motor 23 rotates in one direction by a predetermined angle (here, 6000° from the horizontal axis), the swing angle φI (
Since the stretcher section 4 has swung up to φ2), the rotation is stopped, and the pulse motor 23 is driven to rotate (reversely) in the other direction in order to immediately start rotating in the other direction.

Further, when the pulse motor 23 rotates in the other direction by a predetermined angle (here, 6000° from the horizontal axis), the swing angle φ2 (φ
Since the stretcher part 4 has swung up to 1), the rotation is stopped and the pulse motor 23 is rotated in one direction to immediately start rotating in one direction! (forward rotation) is driven.

Such forward and reverse rotations of the pulse motor 23 are sequentially repeated.

i! that the swing angle φ coincides with (φ2)! I! The angle signal from the rotary sensor 65 is used for the rotation angle, but as another means, by providing an up/down counter that counts the drive pulse signal to the pulse motor 23, the rotation angle of the pulse motor 23 can be used as a virtual signal. A device configured to output a matching signal by comparing the digital set value signal from the manual switch depending on the angle may be used. In this case, the horizontal position fa (oscillation The up/down counter is initialized when the moving angle is zero.

Furthermore, when the swinging is stopped, the swinging angle φ of the stretcher section 4 can be set to zero by pressing the high-speed rotation switch and visually monitoring the meter.

In addition, after receiving the signal from the automatic horizontal stop operation switch and the same operation switch, is the swing angle φ zero or near zero at the deceleration start point? Automatic horizontal stop control means that outputs a stop control signal or a deceleration start signal when the lI is set, and a signal from the operation switch to perform high-speed swinging until the deceleration start No. 43 is received and the deceleration start signal is received. After that, an automatic horizontal stop adult cow 1-cho equipped with speed control means for adjusting the rocking speed so as to perform low-speed rocking may be provided.

Also, when the swing stops or the power is turned off,
When the pulse motor 23 is stopped, the ohm gear 24a and pinion 24bl keep the outer cylinder 22B stopped without rotating, so the stretcher section 4 of the swinging bed does not swing. , strongly and stably supported.

The chest lashing mechanism 30B and the waist and chest lashing mechanisms 30C in the lashing beach Nq30 make the abutment plate 36g at the tip of the clamping member 3G tiltable and fixable, so that this abutment @36a can be made to follow the outer shape of the human body M, thereby preventing the patient, etc., from falling from the bed body 1 during rocking, and the entire surface of the contact plate 36a can be flattened! Since it can be placed along the human body M through the ``52.54'', the clamping force will not be concentrated on a part of the human body M, and the influence of the clamping force on the human body will be extremely small.

Furthermore, when the touch sensor 67 detects that an external force of a predetermined value or more is applied or the torsional force detector 68 detects that a torsional force of a predetermined value or more is applied by the stop mechanism 80, the shaking is immediately performed. Swinging in the moving mechanism 20 can be stopped, and even if an object or person is caught between the stretcher section 4 and the pair of frames 3a and 3b, damage can be minimized.

Furthermore, the weight measurement mechanism 81 can measure the weight at the point where the swing angle φ is zero, and thereby,
The weight of patient M can be accurately measured while the patient is lying down.
Patients' health management can be ensured.

Also, a telescoping machine? 1It90, as shown in FIGS. 26 and 27, with the stopper 93 removed, the cylindrical body 91 of the first support frame portion 10a and the second support frame portion ta
b relative to the rod-shaped body 92, and move from the first support shaft 8a to the second support shaft 8b, as shown by the two-dot chain line in the same figure.
The length can be adjusted by shrinking or expanding.

After the adjustment, the cylindrical body 91 is moved by the stopper 93.
The relative sliding movement between the rod-shaped body 92 and the rod-shaped body 92 is restrained.

This allows the length of the bed to be changed arbitrarily to suit the user, and further reduces the wastage of indoor space (
In addition to being able to adjust the quality of the bed to suit the growth of the child, it also can be used as a hospital bed by adjusting the length as the patient changes, making the space in the hospital room more efficient.

Further, when moving the bed, the length may be contracted to facilitate the movement.

〔Effect of the invention〕

As detailed above, according to the rocking bed with a stop mechanism of the present invention, even if a person leans on the stretcher or an object or person is caught between the stretcher and the pair of frames, The stopping mechanism stops the swinging, which has the advantage of preventing damage to the swinging mechanism and to objects caught in it.
