It is a figure which shows the state which the 1st support member concerning embodiment rotated with respect to the 2nd support member. It is a perspective view of the example of the shape of the tongue part in case the cross section of the 2nd support member concerning embodiment is hexagonal shape.

  Hereinafter, modes for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

  FIG. 1 shows a configuration example of a retractable support structure according to the embodiment. 2A and 2B show a state in which a first support member 10 described later is rotated with respect to the second support member 12. FIG. 2A is a plan view, and FIG. 2B is an enlarged perspective view of a joint portion between the first support member 10 and the second support member 12.

  In FIG. 1, the retractable support structure supports a vehicle-mounted supported body 100 such as a camera, a prismatic and hollow first support member 10, and a second support member connected to the first support member 10. A hinge member 14 that connects the support member 12, the first support member 10, and the second support member 12 so that the first support member 10 can rotate in the direction of arrow A, and the first support member 10 and the second support member. 12, when the first support member 10 stands upright on the second support member 12 on a surface different from the surface on which the hinge member 14 is attached. An engagement member 16 that fixes the first support member 10 and the second support member 12 is provided so as to prohibit rotation with respect to the support member 12.

  The first support member 10 is configured in a prismatic shape. In the example of FIGS. 1, 2A, and 2B, it is configured in a quadrangular prism shape, but is not limited thereto. In particular, a cross section perpendicular to the longitudinal direction is preferably a quadrangular shape (quadrangular column), a pentagonal shape (pentagonal column), or a hexagonal shape (hexagonal column) from the standpoint of availability and processing. Further, the inside of the first support member 10 is hollow (hollow), and may be referred to as a hollow portion hereinafter. In addition, the 1st support member 10 may be processed into the shape of the curve of the angle | corner of the cross section of a prism.

  The second support member 12 is fixed to a vehicle 102 on which the supported body 100 is placed via an appropriate gantry 20 or the like. Here, it is assumed that the vehicle 102 travels in the direction of arrow F. The second support member 12 has the same cross-sectional shape as the first support member 10 in the cross section perpendicular to the longitudinal direction, and when the first support member 10 is rotated to stand upright on the second support member 12 A tongue 18 (see FIGS. 2A and 2B) inserted into the hollow portion so as to substantially contact the inner surface of the hollow first support member 10 is provided.

  As a material which comprises the said 1st support member 10 and the 2nd support member 12, it should just have the intensity | strength which can support the to-be-supported to-be-supported bodies 100, such as a camera. For example, steels such as aluminum, iron, and stainless steel, other metals, plastics (for example, engineering plastics such as ABS resin, PC (polycarbonate), and PA (polyamide) are preferable), carbon fibers, and the like can be given.

  As shown in FIG. 2B, the tongue 18 is formed on the side of the second support member 12 where the hinge member 14 is attached and the side adjacent to the side, and is different from the side where the hinge member 14 is attached. The tongue 18 formed on the side (adjacent side) is formed with a circular or parabolic arc R at the end far from the hinge member 14 to avoid interference when the first support member 10 is rotated. Has been. If the tongue 18 is provided on the opposite side (opposite side) of the side to which the hinge member 14 is attached, the first support member 10 is rotated and the first support member 12 is brought upright when the first support member 10 is rotated. Since it interferes with the member 10, the tongue portion 18 is not provided on the side.

  The example of FIG. 2B is a case where the first support member 10 and the second support member 12 are quadrangular prisms having a quadrangular cross section, and the arc R formed on the tongue portion 18 is an arc. In contrast, when the first support member 10 and the second support member 12 are pentagonal or hexagonal columns having a pentagonal or hexagonal cross section, a parabolic arc is formed.

  FIG. 3 shows a perspective view of an example of the shape of the tongue portion 18 when the second support member 12 has a hexagonal cross section. In FIG. 3, the tongue 18 is formed on the side of the second support member 12 to which the hinge member 14 is attached and the side adjacent to the side, and on a side different from the side to which the hinge member 14 is attached (adjacent side). The formed tongue 18 is formed with a parabolic arc R at the end far from the hinge member 14. If the tongue portion 18 is provided on a side other than the three sides, the first support member 10 interferes with the first support member 10 when the first support member 10 is rotated to stand upright on the second support member 12. Does not provide the tongue 18.

  The hinge member 14 is not limited as long as the first support member 10 and the second support member 12 can be rotatably connected.

  The hinge member 14 is attached across the side of the first support member 10 and the second support member 12 on the side of the traveling direction of the vehicle 102 (the direction of arrow F in FIG. 1). This is because shooting with a camera or the like is normally performed while the vehicle 102 travels forward (in the direction of arrow F in FIG. 1), so that the supported body 100 can be stabilized even when the vehicle 102 speeds up. It is for supporting.

  The engaging member 16 may be a conventionally known catch clip (see JP 2007-63902 A) or the like. However, the engagement member 16 is not limited to the catch clip, and the first support member 10 and the second support member 12 can be fixed when the first support member 10 stands upright on the second support member 12. In addition, it is only necessary to be able to switch between the engaged state (fixed state) and the disengaged state (fixed state released) with a simple operation. A structure (elastic engagement member) that is fixed while being urged by an elastic member such as a spring so that the fixed portion does not come off while the vehicle 102 is running is preferable. By using the engagement member 16 as an elastic engagement member, the first support member 10 and the second support member 12 can be more firmly fixed, and rattling of the connecting portion can be suppressed. In addition, even if a minor failure occurs in the engagement member 16, it is possible to prevent the first support member 10 from falling down completely.

  As shown in FIG. 2A, in the retractable support structure according to the present embodiment, the engagement member 16 is disengaged and the first support member 10 is moved by the hinge member 14 to the second support member 12. Therefore, the work for avoiding obstacles on or around the road can be easily performed in a short time. Further, the rotation of the first support member 10 in this case is performed on the hinge member 14 side (the front side of the vehicle 102). In this case, the retractable support structure according to the present embodiment includes the first support member 10. A third support member 22 that supports the support member 10 is provided. The third support member 22 includes a holding portion 22 a that holds the first support member 10, and the holding portion 22 a receives and holds a part of the body of the first support member 10. It is preferable to attach an elastic material such as rubber to the surface of the holding portion 22a that contacts the first support member 10 because the first support member 10 can be stably held. The third support member 22 can stably support the first support member 10 while avoiding the obstacle.
