There is one described in Publication No. 79, and this conventional rocking hospital bed has a pedestal with branches erected at both ends, and a U-shaped blood vessel with a stretcher supported swingably on both branches. A device includes a member and a swinging mechanism for swinging the U-shaped blood vessel member with a stretcher portion.

In such conventional swinging beds, in order to make the output of the drive device in the swinging mechanism as low as possible,
The distance between the patient's center of gravity and the center of gravity of the gurney's dominant U-shaped blood vessel member, which is a swinging part, is made smaller, but if the patient's weight is heavier than the standard weight, the center of gravity moves upward. Place a weight corresponding to the amount of movement of this center of gravity on the horizontal part of the U-shaped blood vessel member. I put it in place to maintain balance.

] The second cross-shaped support frame portion 101)
The telescoping machine vI90 consists of a cylindrical body 91 having a rectangular cross section as a guide member @1 formed at both ends of the first support frame portion 10a, and a cylindrical body 91 that is fitted inside the cylindrical body 91. ii of the second support frame portion 101 to guide the sliding movement.
f? The rod-shaped body 92 is formed at the end and serves as a guide member for fjS2, and the stopper 93 restrains relative sliding between the cylindrical body 91 and the rod-shaped body 92.

That is, the first and second support frame portions 10a.

10b is mounted so as to be relatively movable.

This rod-shaped body 92 is constituted by a columnar body having a solid cross section or a cylindrical body having a rectangular cross section.

Note that the cylindrical body 91 and the rod-shaped body 92 have a vertical height of p/
Rigidity is increased by making the height larger than the vertical height of the cross members of rJ1 and the second support frame portions 10a and 10b.

Since the split-assembly rocking bed as an embodiment of the present invention is constructed as described above, when splitting, the load converter 69 and other parts are used to connect the stretcher section 4 and the seven runs 9a, 9b. Divided into independent independent part IA.

Since it can be separated into the IB and the mounting part IC, portability during movement can be improved, and when assembling, the stretcher part 4 and the seven runs 9a, 9b are combined in the load converter 69 etc. Can be assembled together. Also,
Maintenance is also easy.

After this assembly, the first and second support shafts 8a+81
] are supported by the double bearings 7a, 7b, allowing the swing axes of the respective support shafts 8a, 8b to be misaligned.

Also, during the swinging, the swinging mechanism 20 causes the power switch 61a of the control system's machining board 64 to move as shown in FIG.
Start signal from 61b (61c) and direction switch 61b (61c
), the rocking is started in response to a rocking direction signal from the rocker, and the left and right rocking angle φ1. φ21 soil, manualless inch knob 61e, 61fh noodle/7-1!
Shut up! In addition to the normal rocking speed, high-speed rotation can be selected based on the input from the high-speed rotation switch 61cl.

Further, as shown in FIGS. 18 to 10, when the pulse motor 23 is driven to rotate in one direction (forward rotation), the outer cylinder 22B is rotated via the reduction gear 24 and the universal joint 26, and the outer cylinder 22B is rotated through the reduction gear 24 and the universal joint 26.
The inner sleeve 22 that engages with the inner sleeve 2B moves up and down, and the arm 21 is swung.

When the pulse motor 23 rotates in one direction by a predetermined angle (here, 6000' from the horizontal axis), the swing angle φ1
Since the stretcher section 4 has swung up to (φ2), the rotation is stopped, and the pulse motor 23 is driven in the other direction to rotate 0 animals v:) in order to immediately start rotation 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 section 4 has swung up to 1), the rotation is stopped and the pulse motor 23 is driven to rotate in one direction (normal rotation) in order to immediately start rotating in one direction.

Such normal rotation and reverse rotation of the pulse motor 23 are repeated in sequence.

The angle signal from the rotary sensor 65 is used to determine that the swing angle φ, (φ2) matches, but the angle signal from the rotary sensor 65 is used.
By providing an up/down counter that counts the drive pulse signal to the pulse motor 23, a signal representing the rotation angle of the pulse motor 23 is compared with a digital set value signal corresponding to the angle from the manual switch to match. A device configured to output a signal may be used, in which case the 7-up down counter is initialized at the horizontal position (swing angle is zero) at the start and at predetermined time intervals.

Further, 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, when it is determined that the swing angle φ is zero or the deceleration start point near zero after receiving a signal from the automatic horizontal stop operation switch and the same operation switch, the stop control signal or deceleration start is generated. An automatic horizontal stop control means that outputs a signal and a signal from a repeating switch are used to perform high-speed oscillation until a deceleration start signal is received, and to perform low-speed oscillation after receiving a deceleration start signal. An automatic horizontal stop mechanism may be provided with speed control means for adjusting the rocking speed.

Also, when the swing stops or the power is turned off,
When the pulse motor 23 is stopped, the worm gear 24a and the pinion 24I prevent the outer cylinder 22B from rotating (it remains stopped, so the stretcher section 4 of the swinging bed does not swing). , strongly and stably supported.

The chest lashing [730B] in the lashing mechanism 30 and the waist and leg lashing mechanism 300 make the abutting plate 36a at the tip of the clamping member 36 tiltable and fixable. The contact plate 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.
Since the entire surface of 6a can be placed along the human body M via the pads 52 and 54, the clamping force is not concentrated on a part of the human body M, and the influence of the clamping force on the human body is 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. r! The swinging of the h mechanism 20 can be stopped, and even if an object or person is caught between the stretcher section 4 and the pair of frames 38t a b, damage can be minimized.

Furthermore, the weight measuring machine M/181 can measure the weight at the point where the swing angle φ is zero, which makes it possible to accurately measure the weight of the patient M while lying down, and to ensure the health of the patient. ! R management can actually be carried out.

In addition, as shown in FIGS. 26 and 27, the telescopic mechanism 90 allows the cylindrical body 91 of the first support frame portion 10a and the second support frame portion 10I) to be moved with the stopper 93 removed. Adjust the length from the first right-hand movement 8a to the second support shaft 8b by sliding it relative to the rod-shaped body 92 and expanding or contracting it. be able to.

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.

As a result, the length of the bed can be changed arbitrarily to suit the user, reducing wasted indoor space, and making it possible to adjust the length of the bed to suit the child's growth. As a bed, the length can be adjusted as appropriate depending on the patient, 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 described in detail above, according to the split-assembly rocking bed of the present invention, the pair of pedestals and stretcher parts can be separated from each other and assembled together, which greatly improves portability when moving. There are advantages that can be improved.
