Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bed which is particularly suitable for hospitalization: e-persons and disabled persons.

In general, inpatient beds are constructed with a high bed surface so that they are suitable not only for patient rest, but also for patient examination and treatment. Therefore, depending on the patient, it may be difficult to get on and off the bed.

Therefore, a system in which the entire bed surface is lowered has been proposed, but it has the disadvantage of poor operability because the operating device is a big problem, the disadvantage of having to raise the mast, and the disadvantage of increasing weight. There is also.

An object of the present invention is to allow a patient or a disabled person to get on and off a bed easily and extremely safely, while giving the patient or disabled person a sense of security.

Furthermore, the operating device for raising and lowering can be simplified, and the bed can also be suitably provided to wheelchair users, as will become clear from the detailed description below with reference to the drawings.

1, ##ih and FIG. 2 show an embodiment of the present invention, in which a bed 1 is provided with a bed frame 2 and a bed cushion 3, and a longitudinally intermediate portion of the bed cushion 3. is hollowed out in an n-shape when viewed from above, and the movable part 5 is provided in this part. The movable part 5 includes a movable part frame 6 and a movable part cushion 7. Furthermore, the movable part 5 is connected to an operating device including an X-shaped link 10 and a hydraulic jack 21.

The length t of the movable part 5 is formed to be larger than the width of the wheelchair, and the wheelchair can be introduced above the movable part 5 when the movable part 5 is lowered.

The bed frame 2 includes a lower horizontal member 8 having an elongated hole 15 for guiding the X-shaped link 10 at the position where the movable part 5 is installed, and an elongated hole for guiding the X-shaped link 10. a vertical member 9 having 16 is attached;
Further, the movable part frame 6 is formed with elongated holes 1 and 4 for guiding the X-shaped ring 41o.

The X-shaped links 10 are arranged on both sides of the movable part 5 in the length direction. , each X-shaped link 10 has a first . It is constructed by combining the second link members' 11 and 12 and connecting them with a pin 13. The lower end of the first link member 11 is pivoted to the lower end of the vertical member 8 by a pin 17.

The upper end portion is engaged with an elongated hole 14 formed in the movable part frame 6 via a pin 18. On the other hand, the lower end of the second link member 12° is engaged with the elongated hole 15 formed in the lower horizontal member 8 through the pin 19, and the upper end is formed in the vertical member 9 by passing the pin 20 upward. It is engaged with the elongated hole 16.

The X
The mold link 10 is capable of holding the movable part 5 in a horizontal state and guiding it in parallel in the vertical direction.

The hydraulic jack 21 is installed below the center of the movable part 5, and is mounted on an operating part (such as a hand lever or a foot lever).
(not shown), so that the movable part 5 can be lowered to a position lower than the bed surface 4 and raised from the lowered position to the same level as the bed surface 4.

The bed of the above embodiment is operated and used as follows.

When removing a patient or a disabled person from the bed 1, move the patient or disabled person to the movable part 5, and then
When the hydraulic jack 21 constituting the operating device is operated in the direction of lowering the movable part 5, the movable part 5 is guided by the X-shaped link 10, as shown by the imaginary line in FIG. 2 and clearly shown in FIG. It is held in a horizontal position and descends in parallel.

Therefore, using the movable portion 5, a patient or a disabled person can be easily and safely lowered from the bed surface 4.

Next, when raising the patient or the disabled person to the same level as the bed surface 4, the movable part 5 is lowered, the patient or the disabled person is placed on the movable part 5, and the hydraulic jack 21 is operated to the upward side. By.

The movable part 5 is guided by an X-shaped link 10 and rises parallel to the bed surface 4. 'Therefore, in this case as well, the patient or the disabled person can be easily and safely raised to the same level as the bed surface 4.

Furthermore, when getting on and off the bed surface 4, the patient or the handicapped person can hold on to the fixed bed cushion 3 around the movable part 50 and support the body while moving up and down the movable part 5. It is possible to get on and off the vehicle extremely safely and with a sense of security for the patient or disabled person.

Furthermore, when handling one wheelchair user, it is possible to lower the movable part 5 and then introduce the wheelchair onto the movable part 5, so that from the movable part 5 to the wheelchair, and vice versa, from the wheelchair to the movable part 5. Transfers can be made easily and safely.

In addition, in the present invention, the movable part 5 is not limited to being provided in the middle part in the length direction of the bed 1, but may be provided in the end part side in the length direction.

The operating device for the movable part '5 is still in the X shape shown in the figure.
The present invention is not limited to a combination of a hydraulic jack 21 and a hydraulic jack 21, and any structure that can hold the movable part 5 in a horizontal state and move it up and down in parallel between the bed surface 4 and a lower position can be used.

The above is the configuration of an embodiment of the bed according to the present invention. According to this configuration, the movable part provided in a part of the length direction of the bed can be raised and lowered in parallel. Use this to move the patient or disabled person to a position much lower from the bed surface.

It also has the effect of being able to be easily raised and lowered from the lowered position to the same level as the bed surface.

In addition, according to the present invention, the movable part can be raised and lowered while maintaining a horizontal state, and when getting on and off the bed, the patient or a disabled person is required to grasp the fixed padded cushion around the movable part. Since the patient's body can be supported while being raised and lowered, the patient or the handicapped person can be raised and lowered extremely safely and with a feeling of security.

Furthermore, according to the present invention, since only a portion of the bed is a movable part, the operating device for the movable part can be simplified, resulting in cost reduction and weight reduction, as well as the effect of improving operability. be.

Moreover, if the length of the movable part is made larger than the width of the wheelchair, the wheelchair can be introduced above the movable part when the movable part is lowered. To easily and safely transfer from a wheelchair to a movable part.

It should be noted that the above description merely shows one embodiment of the present invention, and it will be obvious that various modifications and changes may be made without departing from the spirit of the present invention.
