Description

  The present invention relates to a wheelchair storage device that lifts a wheelchair with an arm that is foldable with respect to a pole installed in a trunk room of an automobile and stores the wheelchair in a trunk room or the like.

Conventionally, as a wheelchair storage device for mounting a wheelchair in a vehicle trunk room or the like, the wagon type can take a large height above the floor of the cargo room, so the system of folding the arm part with respect to the pole installed on the floor is Adopted. In addition, the sedan type has adopted a structure in which the pole part is folded in addition to the folding of the arm part because the floor height is low. And many of these wheelchair storage apparatuses were stored manually. Also, even a wagon car that can take a large height above the floor of the cargo compartment usually interferes with a tonneau cover that is stretched to cover the cargo compartment, so that the tonneau cover could not be used when a wheelchair storage device was installed. Therefore, a compact wheelchair storage device that can be applied to a sedan type as well as a wagon type has been proposed (for example, see Patent Document 1 below).

As shown in FIG. 1, the basic configuration of the telescopic wheelchair storage device of the present invention is such that the wheelchair is lifted by an arm 2 that can be folded with respect to a pole 3 installed in a trunk room of an automobile and stored in a trunk room or the like. The wheelchair storage device 1 includes a movable pole 3A that is movable up and down with respect to the fixed pole 3B, and a movable arm 2A that is slidable with respect to the fixed arm 2B, and an upper end portion of the movable pole 3A and the fixed arm 2B. The vicinity of the rear end portion is pivotally attached to the pivot 8.

  Examples will be described in detail below. As shown in FIG. 1, a pole member 3 of a wheelchair storage device 1 is installed on a floor F of a trunk room of an automobile. A pole drive motor 12 is installed at the lower end of the pole member 3. Actually, the lower end portion of the pole member 3 including the pole drive motor 12 is installed via a pedestal 17 that is rotatable with respect to the floor F as shown in FIG. The pole member 3 includes a lower cylindrical fixed pole 3B and a movable pole 3A fitted to the fixed pole 3B so as to be movable up and down. Although the cross section of the cylindrical fixed pole 3B and the movable pole 3A fitted to the fixed pole 3B so as to be vertically movable is preferably a square, an appropriate cross section such as a circle can be adopted. A female screw pole bracket 5 is fixed to the lower end portion of the movable pole 3A, and a screw rod 7 rotated by a pole drive motor 12 installed at the lower end portion of the fixed pole 3B is screwed to the female screw pole bracket 5. Combined.

  On the other hand, the upper end portion of the movable pole 3 </ b> A and the vicinity of the rear end portion of the arm member 2 are pivotally attached to the pivot 8. The arm member 2 includes a cylindrical fixed arm 2B on the base side (the pivot 8 side) and a movable arm 2A that is slidably fitted to the fixed arm 2B. The cross section of the cylindrical fixed arm 2B and the movable arm 2A that is slidably fitted in alignment with the fixed arm 2B is also preferably a square, but an appropriate cross section such as a circle may be employed. A female screw arm bracket 4 is fixed to the end of the movable arm 2A on the fixed arm 2B side, and the female screw arm bracket 4 is rotated by an arm drive motor 11 installed in the vicinity of the pivot 8 portion of the fixed arm 2A. The threaded rod 6 is screwed.

  Further, the rear end portion 13 of the fixed arm 2B and the upper end portion 14 of the fixed pole 3B are connected by an arm opening guide member 9 that is tensioned when reaching a predetermined length. As shown in FIG. 3, the arm opening guide member 9 receives the upper guide 9 </ b> A on which pins 9 </ b> D (preferably a pair is installed in a sliding direction so as to promote straight advance control) and the pins 9 </ b> D are received. The lower guide 9B in which the long hole 9C is formed is combined. Therefore, the arm opening guide member 9 is in a “play” state until the pin 9D slides within the long hole 9C and reaches the end of the long hole 9C, and the pin 9D reaches the end of the long hole 9C. Then, “tense” is reached.

  As shown in FIG. 1, the upper end portion of the upper guide 9A in the arm opening guide member 9 is connected to the rear end portion of the fixed arm 2B by the shaft support portion 13, and the lower end portion of the lower guide 9B in the arm opening guide member 9 is the shaft. The support 14 is connected to the upper end of the fixed pole 3B. Therefore, if the pole drive motor 12 is rotated and the movable pole 3A continues to rise after the arm opening guide member 9 is tensioned, the rear end portion of the fixed arm 2B is pulled downward by the arm opening guide member 9, and the arm member 2 swings upward about the pivot 8. Accordingly, the arm member 2 can be swung to a predetermined upper position simultaneously with the extension of the pole member 3. If the wheelchair is suspended from a hoisting device 10 (described later) installed at the distal end portion of the arm member 2, it can be lifted as it is. Conversely, until the arm opening guide member 9 is tensed, the arm member 2 is folded (the state shown in FIG. 2), and only the pole member 3 is extended, so that the vehicle body member such as the opening of the trunk room. Thus, the pole member 3 can be freely extended without interfering with.
