Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle having a widening function, and more specifically, to a vehicle having a widening function that enables a widening portion to be configured with a small number of components and that allows a widening portion to be smoothly enlarged and reduced. About.

  2. Description of the Related Art Conventionally, a vehicle having a widening function called a base function forming vehicle has been used to support on-site activities in the event of a disaster. A vehicle having such a widening function is provided with a widening portion provided so as to be expandable along a vehicle width direction from a luggage compartment of a vehicle body, and the widening portion protrudes from the luggage compartment to form a wider space. Is configured. Then, a local command headquarters and the like are installed in the space expanded based on the widening portion.

  In a vehicle having the above-described widening function, if the widening portion has a box-shaped structure integrally including the outer wall and the ceiling wall, as well as the side wall and the floor plate, the widening portion is stored in the luggage compartment. In addition, the floor plate of the widening section interferes with the luggage in the luggage compartment, and the side wall of the widening section blocks the door portion provided at the rear of the luggage compartment. Therefore, in order to avoid such inconvenience, a structure is adopted in which a floor plate and a side wall are folded when the widened portion is stored in a luggage compartment (for example, see Patent Documents 1 to 3).

  For example, in Patent Literature 1, a pair of foldable main widening plates are used as floorboards of the widening portion, and a pair of foldable wall widening plates are used as front and rear side walls of the widening portion. When the widened portions are protruded from the luggage compartment, the pair of main widened plates and the pair of wall widened plates are held in a folded state. Are open. In addition, in order to secure a space for holding the wall widening plate in a folded state before and after the widening portion, it is necessary that the length of the main widening plate constituting the floorboard is shorter than the length of the widening portion, Therefore, a gap is formed in a part of the floor plate before and after the widening portion. In view of this, Patent Literature 1 employs a structure in which a foldable floor widening plate is connected to the lower ends of a pair of wall widening plates. Such a floor widening plate is opened on the main widening plate so as to fill a gap between the wall widening plate and the main widening plate after opening the main widening plate and the wall widening plate, thereby expanding the widening portion. Work is completed.

  However, in the above-described vehicle having the conventional widening function, since a foldable member is used for both the floorboard and the side wall, in addition to the main widening plate forming the floorboard and the wall widening plate forming the side wall, the wall is widened. There is a drawback in that a floor widening plate is required to fill a gap between the widening plate for use and the main widening plate, and that there are many components. Moreover, it is necessary to add a further driving device for driving a foldable member such as a floor widening plate. In addition, since the operation of expanding and contracting the main widening plate and the widening plate for the wall and the operation of tilting the widening plate for the floor are performed separately, the operation of expanding and reducing the widening portion is complicated.

Linked to a location. The pair of floor plates 15A and 15B are folded and held upright when the widened portion 10 is stored in the luggage compartment 3.

  Shutter-type side wall members 20 are installed at front and rear positions of the widening portion 10, respectively. Each side wall member 20 has a structure in which, for example, a plurality of strip-shaped members extending in the vertical direction are connected to each other, and one end of the side wall member 20 is connected to the vehicle body 1 and the other end is connected to the winding device 21 mounted on the widening portion 10. It is connected. The winding device 21 is installed along the outer wall 13 of the widening section 10. The winding device 21 includes a winding roller 22 that winds the side wall member 20 and a guide roller 23 that guides the side wall member 20 to the side wall position. The winding roller 22 constantly rotates the side wall member 20 in the winding direction. It is energizing. It is preferable that the side wall member 20 has a structure in which a plurality of strip-shaped members are connected to each other. However, if necessary, a flexible sheet material can be used. Further, as shown in FIG. 7, a connection sheet 24 may be interposed between the side wall member 20 and the winding roller 21.

  Although the configuration of the winding device 21 is not particularly limited, for example, a configuration as shown in FIGS. 10 and 11 can be employed as a driving mechanism of the winding roller 22. 10 and 11, the winding roller 22 includes a winding pipe 25, a winding core rod 26 inserted into the winding pipe 25, and a curler mounted on one end of the winding pipe 25. 27. The curler 27 has a concave portion 27A that slidably holds one end of the winding core rod 26 and a shaft portion 27B that protrudes outward in the axial direction of the winding pipe 25. A throttle portion 25A is formed at the other end of the winding pipe 25, and the winding core rod 26 is slidably held by the throttle portion 25A. A spring 28 is arranged inside the winding pipe 25 and around the winding core rod 26. The spring 28 has one end engaged with the outer peripheral portion of the curler 27 by frictional force, and the other end narrowed down and engaged with the outer peripheral portion of the winding core rod 26 by frictional force.
