The support shaft 6 of the lower fixed hinge member 50b
6 are a small-diameter shaft portion 66a and a large-diameter shaft portion 6 as shown in FIG.
6b may be connected to each other via a tapered surface to form a truncated cone. The small-diameter concave portion 71 is pressed and supported at the intersection of the small-diameter shaft portion 66a and the tapered surface to connect the upper hinge mechanism 3a as a fulcrum. By relaxing the pressing force of the lower hinge mechanism 3b, the inclined surface acts as a guide means and moves down along the inclined surface of the truncated cone by its own weight, and the large-diameter shaft hole 70 fits into the large-diameter shaft portion 66b. Therefore, there is no need to provide a separate guide means 72 and forcibly guide the vehicle. Note that the small diameter shaft portion 66a and the large diameter shaft portion 66b are provided concentrically, but are not provided concentrically, and the movable hinge member at the time of a fulcrum connecting the other hinge mechanism by shifting the axis center. Of the tapered surface may be changed while maintaining the length of the small-diameter shaft portion 66a. Also, the small diameter shaft portion 66a may be an ellipse instead of a perfect circle, and may be thinner than the diameter of the large diameter shaft hole 70 so as to be easily fitted into the large diameter shaft hole 70 and serve as a fulcrum connecting the other hinge mechanism. Further, it is preferable that the small-diameter shaft portion 66a be a D-cut and a prism having at least one flat surface, and the flat portion of the small-diameter shaft portion 66a allows the support portion of the large-diameter shaft hole 70 to be supported at two points, thereby achieving a stable state. Other hinge mechanisms can be linked. It goes without saying that a prism is a prism having a polygonal bottom surface, and may be a triangular prism, a quadrangular prism or a polygonal prism.

Further, the lower movable hinge member 55b is of a round type in which a small-diameter concave portion 71 is provided on the periphery of the large-diameter shaft hole 70, but the large-diameter shaft hole 70 and the small-diameter concave portion 71 are tangentially arranged as shown in FIG. It may be an elliptical shape that is continuously provided in the shape. Further, only the large-diameter shaft hole 70 may be provided without providing the positioning portion, and the periphery of the large-diameter shaft hole 70 may be appropriately brought into contact with the small-diameter shaft portion 66a to serve as a fulcrum. At this time, at least the small-diameter shaft portion 66a has an inclination angle α of 45 ° as shown in FIG.
The upper hinge mechanism 3a is preferably connected to the large-diameter shaft portion 66b by a tapered surface after connecting the upper hinge mechanism 3a. Further, it is preferable that the inner peripheral lower surface of the large-diameter shaft hole 70 be a tapered surface along the inclined surface of the support shaft 66.

When the support shaft 66 is a truncated cone, FIG.
As shown in FIG. 9 and FIG. 20, it is preferable that a mounting portion 77 having a small diameter shaft portion 66a as a fulcrum is provided on the inclined surface to stabilize the support state, and at this time, the shaft hole of the lower movable hinge member 55b has a large diameter shaft. At the periphery of the hole 70, a fan-shaped concave portion 78 that matches the mounting portion 77 is formed. The hinge mechanism configured in this manner includes a lower movable hinge member 55b as shown by a chain line in FIG.
The upper hinge mechanism 3a can be connected in a stable state with the periphery of the large-diameter shaft hole 70 contacting the small-diameter shaft portion 66a and supported by the mounting portion 77. Then, when the front frame 2 is rotated in this state, as shown by the chain line in FIG.
Is disengaged from the support of the mounting portion 77 in conformity with the mounting portion 77 and the large-diameter shaft hole 70 is formed by the tapered surface of the support shaft 66.
b, and the front frame 2 is rotatably mounted. In addition,
The recess 78 is preferably formed larger than the mounting portion 77 within the semicircle of the large-diameter shaft hole 70.

As shown in FIGS. 21 to 23, a D-cut is performed using the small diameter shaft portion 66a as a truncated cone so that the maximum diameter portion of the small diameter shaft portion 66a is equal to the diameter of the large diameter shaft portion 66b. When the small-diameter shaft portion 66a is used as a support shaft for connecting the other hinge mechanism, the shaft pins of the upper and lower hinge mechanisms are provided linearly and vertically as shown in FIG. Inevitably, the front frame 2 is inclined to connect. For this reason, even if the maximum diameter portion of the small diameter shaft portion 66a is equal to the diameter of the large diameter shaft portion 66b, the edge of the large diameter shaft hole 70 is necessarily supported by the mounting portion 77 as shown in FIGS. Is done. Then, when the shaft hole and the shaft pin of the other hinge mechanism are linear and the front frame 2 is vertical, the large-diameter shaft hole 70 automatically fits in the large-diameter shaft portion 66b, and the mounting portion The opening / closing body can be freely opened / closed without giving the inclination as a guide means to 77.

In the above embodiment,
Although the large-diameter shaft portion 66b and the large-diameter shaft hole 70 are formed as perfect circles, any one of them may be formed in a square shape. For example, when the large-diameter shaft hole 70 is square as shown in FIGS. 24 and 25, the large-diameter shaft portion 66b may be an inscribed circle of the large-diameter shaft hole.
As shown by the five-dot chain line, the rectangular large-diameter shaft hole 70 is brought into contact with the D-cut small-diameter shaft portion 66a in the figure to form a fulcrum that connects the upper hinge mechanism 3a. At this time, since the large-diameter shaft hole 70 is a square hole and the small-diameter shaft portion 66a has a D-cut surface, the upper hinge mechanism 3a is connected in a more stable state because the contact portion as the support shaft is in surface contact. can do. Then, after the upper hinge mechanism 3a is connected, the inclination of the mounting portion 77 serves as a guide means, and the large-diameter shaft hole 70 fits into the large-diameter shaft portion 66b, and the opening / closing body is openably and closably mounted. The placing section 77
Is preferably changed according to the position of the intersection between the small diameter shaft portion 66a and the large diameter shaft portion 66b.
In the case where the mounting portion is located deeper than the center of b and the mounting portion is wide, the tilt angle is set to about 45 ° to 60 °, or the intersection line is positioned before the center of the large-diameter shaft portion 66b. When the mounting portion is narrow, the inclination angle is preferably set to a gentle inclination of about 15 ° to 30 °.

When the large-diameter shaft hole 70 is a square hole, there is always a large-diameter portion having a longer diameter than the diameter of the large-diameter shaft portion 66b. . When the large-diameter shaft hole 70 is fitted into the small-diameter shaft portion 66a, the depth of the large-diameter shaft hole 7 is larger than the width of the D-cut surface in the drawing.
Since the dimension with respect to 0 is small, it is naturally easy to aim at the small-diameter shaft portion 66a when fitted to the side of the D-cut surface. Further, as shown in FIG. 26, the corner portion of the large diameter shaft hole 70 and the corner portion of the small diameter shaft portion 66a are used as fulcrums to support the two surfaces in contact, thereby enabling more stable positioning. Conversely, the large-diameter shaft portion 66b can be a prism instead of a perfect circle. At this time, the large-diameter shaft hole 70 only needs to be a circumcircle of the large-diameter shaft portion 66b.

In the present invention, the small-diameter shaft portion 66a is a shaft portion having a smaller diameter portion than the maximum diameter portion of the large-diameter shaft portion 66b. As shown in FIG. Even if it has the same small diameter portion as the shaft portion 66a, it has no effect in the present invention. Needless to say, it is most stable to support the largest diameter portion of the large-diameter shaft portion 66b in the above-described two-point support and one-sided and two-sided support.

FIGS. 28 to 30 show an embodiment in which the front frame 2 as an opening / closing body is prevented from being unnecessarily removed after being linked by an up / down hinge mechanism. In this embodiment, as shown in FIG.
Along the way, a rib-shaped mounting portion 77 for providing the small-diameter shaft portion 66a as a fulcrum is provided, and a lower end protrudes from the outer periphery of the large-diameter shaft portion 66b to make the outside of the mounting portion 77 a tapered surface.
The large diameter shaft hole 70 serves as a guide part 79 as a guide means for guiding the large diameter shaft part 70 to fit into the large diameter shaft part 66b. on the other hand,
In the large-diameter shaft hole 70 of the movable hinge member 55b, a concave portion 78 that matches the mounting portion 77 is formed similarly to the above-described embodiment, and the outer diameter of the concave portion 78 is at least outside the upper surface of the mounting portion 77. The diameter is larger than the larger of the diameter and the diameter protruding from the outer periphery of the large-diameter shaft portion 66b. Naturally, the length of the large-diameter shaft portion 66b from the large-diameter shaft portion 66b to the lower surface of the mounting portion 77 projecting from the large-diameter shaft portion 66b is selected to be longer than the thickness of the large-diameter shaft hole 70 of the movable hinge member 55b.

Next, this operation will be described.
