Summary of the Invention

Problem to be Solved by the Invention

[0005] Incidentally, some medical devices do not have internal batteries, and require a portable power supply when used outside the home. In this case, the portable power supply must be mounted on the wheelchair in addition to the medical device, and space must be secured to accommodate both the medical device and the portable power supply.

[0006] A major challenge for patients receiving home healthcare is securing a power source. Many home healthcare devices have internal batteries. However, these batteries typically only last a few hours, which becomes insufficient for extended periods away from home.

[0007] Furthermore, medical devices without internal batteries cannot be used outdoors. In this case, it is necessary to carry a portable power supply in addition to the medical device itself to provide power to it.

[0008] Furthermore, patients receiving home healthcare often own portable power supplies for use during power outages or when going out. However, lifting heavy medical equipment and portable power supplies and loading and unloading them onto a wheelchair each time they go out is not an easy task.

[Figure 3] Figure 1 is a side view of the wheelchair, showing the trolley in its storage position. [Figure 4] This is a side view showing a wheelchair according to a second embodiment of the present invention. [Figure 5] This is a perspective view showing a portable power supply. [Modes for carrying out the invention]

[0046] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiments described below are all general or specific examples. The shapes, components, arrangement positions of components, and connection configurations shown in the following embodiments are examples only and are not intended to limit the present invention. Dimensions are not precisely shown in each figure. In each figure, the same or similar components are denoted by the same reference numeral.

[0047] (First Embodiment) First, as a first embodiment of the present invention, we will describe, for example, the wheelchair 1A shown in Figures 1 to 3. Figure 1 is a perspective view showing wheelchair 1A. Figure 2 is a side view showing wheelchair 1A with the trolley 50 in the attachment / detachment position. Figure 3 is a side view showing wheelchair 1A with the trolley 50 in the storage position.

[0048] The wheelchair 1A of this embodiment is an electric wheelchair and comprises a vehicle body frame 2 and a plurality of (four in this embodiment) wheels 3 and a seat 4 attached to the vehicle body frame 2.

[0049] The vehicle frame 2 is not particularly limited in terms of material, shape, etc., and can be modified as appropriate. For example, the vehicle frame 2 in this embodiment consists of a base frame 2a that forms the lower part, a seat frame 2b that forms the upper part, a pair of left and right side frames 2c that connect the base frame 2a and the seat frame 2b, and a back frame 2d that extends upward from the rear of the seat frame 2b. The front part of the base frame 2a extends forward of the seat frame 2b, forming a mounting part that serves as a footrest.

[0050] The multiple wheels 3 consist of a pair of front wheels 3a and a pair of rear wheels 3b. The front wheels 3a are rotatably mounted on the front side of the base frame 2a (vehicle frame 2). The rear wheels 3b are rotatably mounted on the rear side of the base frame 2a (vehicle frame 2).

[0051] The seating portion 4 is not particularly limited in terms of material, shape, etc., and can be modified as appropriate. For example, the seating portion 4 in this embodiment has a seat cushion 4a, a backrest 4b, and a pair of left and right armrests 4c. The seating portion 4 is fixedly supported to the vehicle frame 2 via a seat frame 2b and a back frame 2d.

[0052] The vehicle frame 2 is equipped with a drive motor (not shown), which is an electric motor that rotates the wheels 3, a battery (not shown) that supplies power to the drive motor, and an operating unit 5 that controls the driving of the wheels 3.

[0053] In the wheelchair 1A of this embodiment, forward or reverse movement is possible by rotating the front wheels 3a or rear wheels 3b, which serve as drive wheels, with a drive motor. Furthermore, turning is possible by applying a rotational difference between the left and right drive wheels. Omni-wheels or Mecanum wheels may be used as drive wheels. Alternatively, turning may be achieved by steering the front wheels 3a or rear wheels 3b.

[0054] In the wheelchair 1A of this embodiment, the battery is built into the vehicle frame 2, and the battery is charged by connecting a charging plug (not shown) to the vehicle frame 2. Alternatively, the battery may be detached from the vehicle frame 2 and charged using a charger.

[0055] The control unit 5 has an operating lever 5a on the front side of one of the pair of left and right armrests 4c (the right side in this embodiment). In the wheelchair 1A of this embodiment, the user (occupant) can operate the operating lever 5a while seated in the seating unit 4 to move the wheelchair 1A forward, backward, or turn.

[0056] Incidentally, in the wheelchair 1A of this embodiment, it is possible to mount medical equipment 100, such as a ventilator, and a portable power supply 200 that supplies power to the medical equipment 100, on the vehicle frame 2.

[0057] In other words, the portable power supply 200 is an example of a power supply device that has a power storage unit and outputs the power stored in the power storage unit to the outside. On the other hand, the medical device 100 is an example of a power consumption device that is connected to the portable power supply 200 via a power line in a manner that allows for power transmission.

[0058] Specifically, the vehicle frame 2 is provided with a first space S1 located below the seat surface 4a (seating area 4) and a second space S2 located behind the seat surface 4a and backrest 4b (seating area 4) as holding parts.

[0059] The first space S1 is provided between the base frame 2a and the seat frame 2b. The second space S2 is located behind the first space S1 and is provided on the rear side of the vehicle body frame 2.

[0060] In this embodiment, the trolley 50 (medical equipment 100 and portable power supply 200) held in the first space S1 is positioned lower than the seating area 4 in the vertical direction, and overlapping with at least a portion of the seating area 4 when viewed from above in the vertical direction.

[0061] In this implementation, wheelchair 1A can be equipped with medical equipment 100 and a portable power supply 200 in either the first space S1 or the second space S2 of the vehicle frame 2.

[0062] Furthermore, the vehicle frame 2 has a detachable mechanism 20 for detachably attaching a trolley 50, which serves as a subframe on which medical equipment 100 and a portable power supply 200 are mounted.

[0063] The trolley 50 can be any trolley with casters capable of carrying the medical equipment 100 and the portable power supply 200, and its configuration is not particularly limited. In addition, the subframe that is attached to and detached from the vehicle frame 2 via the attachment / detachment mechanism 20 can be any subframe capable of carrying (fixing) the medical equipment and the portable power supply, in addition to the wheeled subframe such as the trolley 50 described above. Furthermore, the attachment / detachment mechanism 20 is not limited to a configuration that can be attached to and detached from the vehicle frame 2 without the use of tools, but may also be a configuration that can be attached to and detached using tools.

[0064] The detachable mechanism 20 has a pair of left and right guide rails 6 attached to the upper surface of the vehicle frame 2. The pair of guide rails 6 are located on both the left and right sides of the upper surface of the vehicle frame 2 and extend in the front-rear direction of the vehicle frame 2. The pair of guide rails 6 may also be configured to be embedded in the upper surface of the vehicle frame 2.

[0065] Furthermore, it is preferable that the uppermost part of the section that holds the trolley 50 (medical equipment 100 and portable power supply 200) is positioned lower in the vertical direction than the uppermost parts of the front wheels 3a and rear wheels 3b.

[0066] Furthermore, it is preferable that at least one of the front wheels 3a and rear wheels 3b has a left wheel and a right wheel that are spaced apart from each other in the left-right direction, and that the trolley 50 (medical equipment 100 and portable power supply 200) is positioned between a left imaginary line extending in the front-rear direction through the right end of the left wheel and a right imaginary line extending in the front-rear direction through the left end of the right wheel when viewed vertically upward.

[0067] Furthermore, the front wheels 3a have a left front wheel and a right front wheel that are spaced apart from each other in the left-right direction, the left imaginary line passes through the right end of the left front wheel, and the right imaginary line passes through the left end of the right front wheel. Preferably, the front wheels 3a are positioned in front of the trolley 50 (medical equipment 100 and portable power supply 200) held in the first space S1 in the front-rear direction, and are positioned between the left imaginary line and the right imaginary line when viewed from above in the vertical direction.

[0068] Furthermore, the front wheels 3a have a left front wheel and a right front wheel that are spaced apart from each other in the left-right direction, and the trolley 50 (medical equipment 100 and portable power supply 200) is positioned between a left imaginary line extending in the front-rear direction through the right end of the left front wheel and a right imaginary line extending in the front-rear direction through the left end of the right front wheel when viewed from above in the vertical direction, and it is preferable that the medical equipment 100 is positioned in front of the trolley 50 (medical equipment 100 and portable power supply 200) in the front-rear direction, and is positioned between the left imaginary line and the right imaginary line when viewed from above in the vertical direction, and is detachably held by the trolley 50, and is connected to the portable power supply 200 held by the trolley 50 so as to be able to transmit power via a power line.

[0069] In the attachment / detachment mechanism 20, the casters 51 of the bogie 50 are engaged with a pair of guide rails 6 from the front of the vehicle frame 2, and the bogie 50 is moved along the surface of the base frame 2a toward the rear first space S1. At this time, the casters 51 of the bogie 50 engaged with the pair of guide rails 6 are guided toward the rear along the pair of guide rails 6. Also, in the storage position at the rear of the vehicle frame 2, the bogie 50 is housed in the first space S1.

[0070] As a result, in the wheelchair 1A of this embodiment, the medical equipment 100 and portable power supply 200, along with the trolley 50, can be mounted (held) in the first space S1 on the wheelchair frame 2. Furthermore, the trolley 50, once housed in its storage position, can be fixed in that position by a locking mechanism provided on the casters 51.

[0071] Meanwhile, the attachment / detachment mechanism 20, after releasing the locking mechanism of the trolley 50 described above, moves the trolley 50 housed in the first space S1 toward the attachment / detachment position in front. At this time, the casters 51 of the trolley 50, which are engaged with the pair of guide rails 6, are guided forward along the pair of guide rails 6. Furthermore, at the attachment / detachment position on the front side of the vehicle frame 2, the engagement of the casters 51 with the pair of guide rails 6 is released.

[0072] As a result, in the wheelchair 1A of this embodiment, the medical equipment 100 and portable power supply 200 can be removed from the vehicle frame 2 along with the trolley 50.

[0073] In addition, the wheelchair 1A of this embodiment may be configured to have a locking mechanism (not shown) on the vehicle frame 2 side, such as a wheel stopper, to secure the vehicle frame 50 housed in the first space S1, rather than being limited to the locking mechanism provided on the caster 51 of the trolley 50 as described above.

[0074] As described above, in the wheelchair 1A of this embodiment, the medical equipment 100 and portable power supply 200 can be mounted on the vehicle frame 2 along with the trolley 50. This makes it possible to reduce the effort required to transfer the medical equipment 100 and portable power supply 200 to the wheelchair 1A.

[0075] Furthermore, in the wheelchair 1A of this embodiment, a heavy trolley 50 (medical equipment 100 and portable power supply 200) can be stably mounted in the first space S1 of the vehicle frame 2, thus maintaining the driving stability of the wheelchair 1A. Moreover, it does not get in the way of the person pushing the wheelchair 1A.

[0076] Furthermore, in wheelchair 1A of this implementation, the direction in which the trolley 50 is attached to and detached from the vehicle frame 2, and the direction in which the trolley 50 is guided, are both the same as the front-to-back direction of the vehicle frame 2. This makes it possible to easily attach to and detach the trolley 50 and guide it in the front-to-back direction of the vehicle frame 2.

[0077] (Second Embodiment) Next, as a second embodiment of the present invention, a wheelchair 1B shown in Figure 4 will be described. Figure 4 is a side view of wheelchair 1B. In the following explanation, parts equivalent to those of wheelchair 1A will not be described, and the same reference numerals will be used in the drawings.

[0078] In this embodiment, wheelchair 1B is configured such that a medical device 100 is mounted in one of the two spaces (first space S1 in this embodiment) provided on the wheelchair frame 2, and a portable power supply 200 is mounted in the other space (second space S2). Otherwise, it has basically the same configuration as wheelchair 1A described above.

[0079] In other words, in the wheelchair 1B of this embodiment, the medical equipment 100 and the portable power supply 200 are mounted separately in the first space S1 and the second space S2 of the wheelchair frame 2.

[0080] As described above, in the wheelchair 1B of this embodiment, the heavy medical equipment 100 and portable power supply 200 can be stably mounted in the first space S1 and second space S2 of the vehicle frame 2 described above, making it possible to maintain the driving stability of the wheelchair 1B.

[0081] It should be noted that the present invention is not limited to the embodiments described above, and includes various modifications to the embodiments described above without departing from the spirit of the present invention. For example, in the wheelchairs 1A and 1B described above, either the medical equipment 100 or the portable power supply 200 may be mounted in at least one of the first space S1 and second space of the vehicle frame 2 described above.

[0082] Therefore, it is also possible to have a configuration in which the portable power supply 200 is mounted in the first space S1 and the medical equipment 100 is mounted in the second space S2. Alternatively, it is also possible to have a configuration in which the medical equipment 100 and the portable power supply 200 (on a trolley 50) are mounted to either the first space S1 or the second space S2 from the rear side of the vehicle frame 2.

[0083] Furthermore, with wheelchairs 1A and 1B, it is possible to load not only the medical equipment 100 and portable power supply 200 mentioned above, but also other luggage in the first space S1 or second space S2 of the vehicle frame 2.

[0084] The portable power supply 200 is a power supply device capable of housing a battery pack 201, which serves as an energy storage unit, inside, as shown in Figure 5, for example. Specifically, the portable power supply 200 has an opening 200a, a housing section (not shown) that allows the battery pack 201 to be inserted and removed through the opening 200a, and a lid 200b that opens and closes the opening 200a.

[0085] In this case, if the opening 200a of the portable power supply 200 in the first space S1 is positioned to face forward in the front-to-back direction, it is possible to insert and remove the battery pack 201 from the portable power supply 200 through the opening 200a from the front side of the wheelchairs 1A and 1B.

[0086] Furthermore, it is preferable that the movement trajectory of the battery pack 201 when it is inserted or removed through the opening 200a is provided so as not to overlap with the left front wheel and the right front wheel as described above. [Explanation of symbols]
