Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a transport device for sick, injured, physically disabled, etc. (hereinafter collectively referred to as "patients"), and can be widely used in hospitals and rehabilitation facilities. It is.

<Prior art> A stretcher (carrier) is used when moving a person who is unable to walk by themselves from a hospital bed for treatment or other purposes. Commonly used stretchers require several people to transfer patients, which puts heavy labor on caregivers. In order to solve this problem, a stretcher has been proposed in which a belt can be used to load and unload a patient without relying on the physical strength of the caregiver. Special Publication No. 56-24536, Special Publication No. 5G-34
These are those described in Publication No. 298, Japanese Utility Model Publication No. 57-50015, and the like. However, these stretchers only had the function of transporting the patient's body in a flat position, and could not respond to patients' requests to sit up and look at the scenery or sunbathe.

<Objective of the Invention> The present invention provides a transportation device that allows a patient to be loaded and unloaded using a belt, and that also deforms into a sofa-like shape and allows the patient to sit up and take an exposed position. The purpose is to

<Structure of the Invention> In the present invention, a plurality of movable decks, each equipped with a scoop belt for scooping up a patient, are arranged in parallel on the top surface of the movable table, and this group of movable decks is extended from the side of the movable table to scoop up the patient. loading and unloading. Each movable deck can change its inclination independently from each other by the support means supporting it, thereby changing the patient support surface into a sofa shape.

1 <Example> An example will be described below based on the figures. In Figure 8,
1 is a bed stand, 2 is a pine dress, 3 is a futon, and 4 is a patient lying on the futon 3. Reference numeral 10 denotes a transportation device according to the present invention, and its main body is essentially a moving platform 11 constructed from a combination of steel materials. The structure will be explained with reference to figures other than FIG. Rod-shaped handles 12 and 13 are provided at the longitudinal ends and side surfaces of the movable platform 11, respectively. The moving platform 11 is supported by two sets of wheels. - set is a wheel group for normal running, and is composed of a pair of front wheels 14.14 and a pair of rear wheels 15.15. Rear wheel 15.1
5 is a free wheel. The other set is a group of wheels for lateral movement, which is composed of pairs of lifting wheels 16, 16, 17, and 17 arranged on both sides of the moving platform 11 in the longitudinal direction. Each elevating wheel is raised and lowered by an electric actuator 18, and is usually raised to a higher position than the normal traveling wheel group. Further, each lifting wheel faces a direction perpendicular to the longitudinal direction of the movable platform 11. Reference numerals 19 and 20 21 denote support grooves constituting the upper surface of the movable table 11, which are arranged in order in the longitudinal direction of the movable table 11. Support □Q, T luck 19, 20.
The upper surfaces of the movable table 11 normally constitute a single or horizontal plane, and are each inclined at a predetermined angle within a vertical plane that includes the longitudinal direction of the movable table 11, if necessary. What makes this possible is the following support structure. First, the support deck 19 has one end adjacent to the support deck 2o pivoted to the slider 22. The slider 22 is attached to rails 23.23 provided on the side edges of the movable table 11, and is only capable of linear movement parallel to the longitudinal direction of the movable table 11.

The slider 22 is moved by an electric actuator 24 fixed to the moving table 11. Further, the substantially central portion of one support deck and the slider 22 are connected by an electric actuator 25 to support the support deck 19. Support deck 20
The central portion is pivotally supported by columns 26 and 26 provided on the movable table 11. Furthermore, the end near the support deck 19 and the moving platform 1
1 is connected by an electric actuator 27. The support deck 21 is attached to the end of the support deck 20 by a hinge 28, and the vicinity of the center of the support deck 21 is connected to the movable table 11 by an electric actuator 29. The electric actuators 18, 24, 25, 27, and 29 described above are similar to jacks, and slowly move the rondo in and out with strong force. The current supply is handled by a battery 30 attached to the side of the moving platform '11.

- A pair of movable decks 31, 32, 33 are placed on the upper surface of each of the support decks 19, 20, 21. Each movable deck has a pair of scoop belts 34, 34 and crawlers 35, 35 on its upper and lower surfaces, some of which protrude outside the support deck. The scoop belt 34 and crawler 35 are all oriented perpendicular to the longitudinal direction of the carriage 11. Each movable deck 31, 32, 33 has a motor box 36 at its end, in which the speed reducer 'a'
It houses an electric motor 37.38 with AM. The electric motor 37 connects the electric motor 38 to the sprocket 39 of the scoop belt 34.
are connected to the sprocket 40 of the crawler 35 by a non-slip winding transmission means such as a chain or a timing belt to transmit rotation. The power source for the electric 137°38 is a battery, as in the case of the electric actuator. Furthermore, each movable deck 31, 32, 33 has a moving guide 41 fixedly installed in the center thereof.

The moving guide 41 is a rectangular pipe-shaped section I having a slit on the lower surface, and receives the rail 4 self-fixed on the upper surface of each support deck 19.20.degree. 21. The shape of the rail 42 is shown in FIG. In the part far from the motor box 3; 6, there is a space of 1°) between the overhanging part 3 and the lower edge of the moving guide 41 at the upper end, and the movable decks 31, 32.
3 can float within a certain height range. This means that the movable deck can tilt relative to the support deck as shown in FIG. Note that in the illustrated embodiment, consideration is given only to preventing the moving guide 41 from separating upward;

1 may be provided with suitable restraining means at the end thereof.

Next, the effect will be explained. When moving patient 4 to another location,
First, the transport device 10 is placed parallel to the bed 1. At this time,
The transport device 10 may be separated from the bed. Next, the electric actuator 18 lowers the lifting wheels 16.17, lifts the front and rear wheels 14.15, and lifts the lifting wheels 16.17.
17 supports the transport device, 10; After that, handle 13
Push the transport device 10 and bring it to the side 1 of the bed 1 as shown in FIG. When the lifting wheels 17 are retracted as shown in FIG. 9, the entire transport device 10 is tilted toward the bed 1, and the ends of the movable decks 31, 32, and 33 are lowered onto the futon 3.

The inclination and height of the transport device 10 are controlled by the degree of protrusion of the lifting wheels 16°HH. Then the electric motor r , +3 fs
is driven, and the crawler 35 is moved in the direction in which the movable decks 31, 32, and 33 output a value of 1≦1. At the same time, the -i coupe belt 34 is moved so that its upper surface flows toward the motor box 36. Movable deck 31.32. '33 is guided by the rail 42 and advances from the longitudinal side of the movable platform 11. Due to its floating structure, movable deck 31.32
゜33 follows futon 3 and patient 4 well while following the ups and downs on the path.
invade between the bodies of If the feeding speed of the scoop belt 34 is made equal to the advancing speed of the movable deck, the entry can be carried out smoothly.

When the movable decks 31, 32, and 33 slip and get under the patient 4, the crawler 35 is stopped and only the scoop belt 34 continues to operate. The patient 4 is then carried to the back of the movable deck 31, 32, 33 as shown in FIG. When the patient 4 reaches a predetermined position, the scoop belt 34 is stopped and the crawler 35 is moved in the opposite direction. Then, the movable deck 31.3-2.33 begins to retreat while supporting the patient 4, as shown in FIG. Movable deck 3
When 1.32.33 has retreated to a position where there is no problem in terms of weight balance, the lifting wheels 17 are pushed out and the transport device 10 is moved horizontally. After that, the transport device 10 is pulled from the bed 1,

, 74.15, and move it to its destination.

When placing patient 4 on another or original bed, the procedure is reversed. That is, the movable deck 31, 32, 33 is placed on the bed and advanced until the end reaches the center of the bed. After the movable deck stops, the fucoob belt 34 is moved in the opposite direction to move the patient 4 to the bed side. patient 4
When the scoop reaches the end of the movable deck, remove the scoop belt 3.
When the deck is moved back while moving patient 4, patient 4
is left in that position.

After scooping up the patient 4 with the movable decks 31, 32, 33, when the patient 4 is desired to take an upright posture, the transport device 10 is transformed as shown in FIG. 12. That is, the slider 22 is moved to the right side in the figure, and the electric actuator 25 flips up the support deck 19, and the electric actuator 2
