Description

Wheelchair fixing device Technical Field The invention relates to a wheelchair fixing device. Background Patent document 1 discloses a floor of a wheelchair mounting space in which an engagement groove is provided in a floor inclined so as to be lower on the rear side in the direction of entrance of a wheelchair, and the wheelchair is temporarily fixed. Patent document 1 Japanese patent application laid-open No. 2022-152508 Disclosure of Invention In the technique of patent document 1, when the vehicle is driven off, the wheelchair user is burdened with the need to ride on the steps in order to move from the temporarily fixed state. The subject of the present embodiment is to reduce the burden on the wheelchair user. A wheelchair securing device according to an embodiment of the present invention includes: A base plate which is provided in a state of being continuous with the ground and supports a wheelchair that has moved from the ground, wherein, in the wheelchair securing device, The base plate is configured to be inclined downward below the ground surface with a connection portion with the ground surface as a fulcrum when the wheelchair is placed. Effects of the invention According to the present invention, the burden on the wheelchair user can be reduced. Drawings Fig. 1 is a schematic side view schematically showing the structure of a wheelchair securing device according to an embodiment of the present invention. Fig. 2 is a schematic side view schematically showing the structure of a wheelchair securing device and a locking mechanism provided in the wheelchair securing device according to an embodiment of the present invention. Fig. 3 is a schematic plan view schematically showing the structure of a wheelchair securing device and a locking mechanism provided in the wheelchair securing device according to an embodiment of the present invention. Detailed Description Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. In the description of the present embodiment, the same or corresponding portions will be omitted or simplified as appropriate. With reference to fig. 1 to 3, an outline of a wheelchair securing device 10 according to the present embodiment will be described. Fig. 1 is a schematic side view schematically showing the structure of a wheelchair securing device 10 according to this embodiment. In the present embodiment, the wheelchair securing device 10 is configured to be mounted on a vehicle. The vehicle may be any vehicle, such as an autonomous vehicle. The wheelchair securing device 10 includes a base plate B1, and the base plate B1 is provided continuously with the ground F1 and supports a wheelchair WC moving from the ground F1. The wheelchair securing device 10 may further include a support plate B2, and the support plate B2 extends upward from the base plate B1 to support the wheelchair WC on the base plate B1 from behind. In the present specification, "upper" refers to a direction indicated by an arrow X, as shown in fig. 1. As shown in fig. 1, the floor surface F1 has an inclined surface F2 extending obliquely to the lower portion of the base plate B1. A spring portion S is disposed between the lower surface of the substrate B1 and the upper surface of the inclined surface F2. When the wheelchair WC 'on the ground F1 moves and is placed on the base plate B1 (wheelchair WC), the base plate B1 is pressed by the self weight of the wheelchair WC to sink (base plate B1'), and the wheelchair WC is temporarily fixed. When the wheelchair WC is withdrawn from the substrate B1, the substrate B1' is returned to the original position (substrate B1) by the restoring force of the spring portion S. In the case of using a wheelchair for a vehicle, it is necessary to fix the wheelchair from the viewpoint of safety. In a conventional welfare vehicle or the like, an auxiliary person uses a belt or the like to fix a wheelchair. However, for example, in an unmanned automatic vehicle, no assistance personnel are assumed. According to the present embodiment, the wheelchair securing device 10 has a state (normal state) in which the floor surface F1 is flat with the base plate B1 and a state (temporary securing state) in which the base plate B1' is located below the floor surface F1. According to this structure, when the wheelchair WC moves to the substrate B1, the substrate B1 automatically descends to be temporarily fixed. Therefore, the user of the wheelchair WC can fix the wheelchair even without relying on an auxiliary person. When the wheelchair WC moves forward during the vehicle-out, the base plate B1' is returned to the original position (base plate B1) by the restoring force of the spring portion S. Therefore, as the wheelchair WC advances, the angle with the ground becomes gentle and easy to move. Thus, the burden on the wheelchair user is reduced. In the p
