    Height adjustable wheelchair docking system
    Technical field of the invention
    The present invention relates to transportation of wheelchair users, and more particularly to means adapted to secure the wheelchair into a transport vehicle.
    Background of the invention
    The welfare and safety of persons being transported in wheelchairs is of ever increasing concern, and many jurisdictions have enacted stringent safety requirements for devices to secure the wheelchair into the transport vehicle and the occupant into the wheelchair. Numerous solutions, most of which are reasonably effective, have been suggested in the prior art, but they frequently require the attachment of a plurality of straps or the like to one or more anchor points in the transport vehicle. After attachment, the straps must be tightened either by the wheelchair occupant or by an attendant. Often, the wheelchair occupant has neither the physical strength nor the manual dexterity to manipulate the necessary straps and the like. This means that the attendant, or vehicle driver, must spend several minutes securing each wheelchair in his/her charge into the vehicle. There have been some attempts to provide self-attachment devices in the past and attention is directed to U.S. Pat. No. 7,229,238 in which a locking mechanism is secured beneath a wheelchair and releasably locked to a docking station similarly mounted under the wheelchair, on the floor of the vehicle. While reasonably effective in certain circumstances, it does not solve the problem that wheelchairs are constructed differently, and that the distance between the locking mechanism secured beneath the wheelchair and the docking station thus will vary. Hence, such a solution is impractical for transport vehicles used for public service, or for service of different
    DK 2017 00233 A1 passengers in general.
    Thus, there is a need for an automatic wheelchair docking system for transport vehicles used for public service, or for service of different passengers in general, that can, if desired, be operated automatically by the attendant from a central location, or that can be operated manually by either the wheelchair occupant or by the attendant.
    Summary of the invention
    A first aspect relates to a height adjustable wheelchair docking system adapted for releasably securing a wheelchair to the floor of a transport vehicle comprising:
    - a base frame with an open end, and adapted for rigid attachment to the floor of a transport vehicle;
    - a middle frame adapted for sliding back and forth in a horizontal direction within the base frame and through the open end;
    - means configured to slide the middle frame in relation to the base frame; and
    - a top frame adapted for covering at least a part of the base frame and middle frame, and adapted to move up and down in a vertical direction in relation to the base frame when the middle frame is sliding back and forth in a horizontal direction within the base frame and through the open end; wherein the top frame further comprises a female or male docking fixture adapted for locking engagement with a male or female docking fixture on a wheelchair.
    In one or more embodiments, the middle frame comprises guide tracks in the bottom part, and wherein at least a part of a fastening means adapted for providing rigid attachment of the base frame to the floor of a transport vehicle is configured for slidingly and/or rollably engagement with said

    In one or more embodiments, the means configured to slide the middle frame in relation to the base frame is configured to horizontally slide the middle frame to a predefined position relative to the base frame in response to a user input signal. Thereby, the user may adjust the height according to his/her individual needs; e.g. if the user has different types of wheelchairs, or if the height adjustable wheelchair docking system is used in transport vehicles used for public service, or for service of different passengers in general.
    As used in the specification and the appended claims, the singular forms a, an, and the include plural referents unless the context clearly dictates otherwise. Ranges may be expressed herein as from about or approximately one particular value and/or to about or approximately another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent about, it will be understood that the particular value forms another embodiment.
    It should be noted that embodiments and features described in the context of one of the aspects of the present invention also apply to the other aspects of the invention.
