Abstract

PROBLEM TO BE SOLVED: To ensure weatherability and wear resistance, and double an opening stopper, by arranging a guide face and an engaging part on a fixed member, and swingably fitting a swing member hanging down a circular head part on the lower face and having a guide part, an engaging groove, and a stopper in the former. SOLUTION: In the counterclockwise opening facility of a door 1, a circular head part 30 insertedly fitted to the inside circular arc face of an engaging part 22 is slid on the circular arc face, and a receiving groove 39 is separated from a projecting piece 20. Next, accompanying counterclockwise sliding of a sliding material 25 along a circular arc like guide face 16, the engaging part 22 is gradually engaged with an engaging groove 31. Consequently, the circular head part 30 is fitted to the short circular arc face of the engaging part 22, it is swung while supporting a load on the door 1 side, and wear of the sliding face is reduced and generation of frictional sound is reduced. Further, by sliding on the circular arc like guide face 16 through the sliding material 25, the contact area is made small and the distance from the rotational center is lengthened so as to reduce wear. Hereby, generation of frictional sound can be reduced so as to smoothly swing the door 1.

The fixing member 11 described with reference to FIG.
The operation of the door structure in which the fitting hinge 5 including the swing member 26 and the fitting member 5 is assembled will be described. FIG. 2A is a schematic partial cross-sectional view when the door is closed. The fitting hinge 5 fits the longitudinal end of the arc-shaped protrusion 27 of the swinging member 26 from the fitting end 24 of the fixing member 11. Then, the circular head 30 is inserted into the circular arc surface inside the engaging portion 22, and the sliding member 25 inserted into the concave groove 29 of the guide portion 28 is assembled in contact with the circular arc guide surface 16. ing. On the other hand, the vertical portion 12 and the horizontal portion 1 of the frame material attaching portion 14
An upper frame member 8 (only part of which is shown) is fixed to 3 by a fixing tool such as a tapping screw (not shown), and the door 1 (only part of which is shown) is provided between the left hanging piece 36 and the right hanging piece 37 of the oscillator mounting portion 35. )
Is fixedly fitted with a fixing tool such as a rivet (not shown). Here, with respect to the clockwise movement of the door 1, the support portion 32 of the swing member 26 is held in a stopped state by the left overhanging portion 15 of the fixed member 11 abutting. Door 1 in this state
Of the fixing member 11 from the protruding piece 20 of the fixing member 11 fitted in the receiving groove 39 of the swinging member 26.
And acts on two points separated by a tensile force to reduce impact and increase stability. Further, the bending moment acting on the base of the swinging member 26 is reduced because the support portion 32 is abutted against the left overhanging portion 15.

FIG. 2 (b) is a schematic partial cross-sectional view during the opening of the door.
The operation of each part of the fitting hinge 5 is such that when the door 1 is open counterclockwise, the circular head 30 inserted into the arc surface inside the engagement portion 22 slides on this arc surface, and the receiving groove 39 The sliding member 25 made of, for example, a high molecular weight polyethylene resin, which is separated from the fitted protruding piece 20 and is inserted into the concave groove 29 of the guiding portion 28 at the tip of the arc-shaped projecting portion 27, The engaging portion 22 gradually fits into the fitting groove 31 as it slides clockwise. Since the circular head 30 is fitted into the short circular arc surface of the engagement portion 22 and swings while supporting the load on the door 1 side, the wear of the sliding surface is reduced and the generation of friction noise is reduced.
Further, the sliding distance of the arc-shaped guide surface 16 for holding the swing trajectory of the circular head 30 is long, but the sliding is via the sliding material 25, the contact area is small, and the distance from the rotation center is long. Therefore, wear is reduced, friction noise is less generated, and the door 1 can swing smoothly. Here, without using the sliding material 25,
The guide portion 28 may slide directly on the arcuate guide surface 16, and even in this case, it is necessary that the guide portion 28 be shaped so as to have a small contact area to minimize wear.

FIG. 2C is a schematic partial cross-sectional view when the door is opened. The operation of each part of the fitting hinge 5 is such that the guide 1 abuts against the locking piece 23 while the door 1 is open counterclockwise. At the same time as the tip of the engaging portion 22 reaches the inner portion of the fitting groove 31, the stopper 38 is abutted against the outer surface of the holding portion 21 and FIG.
And is stopped at a position approximately 100 degrees counterclockwise from the position of. Here, the gasket 40 suspended by hanging the upper end into the circular groove 19 of the bulging portion 18 of the fixing member 11.
The lower portion is pressed along the right side gradient of the stopper 38 so that rainwater flowing down from above can be prevented from entering the cargo box. In this state, when the door 1 is opened, the opening is stopped by the force of the guide portion 28 to the left overhanging portion 15 and the pressing force from the holding portion 21 of the stopper 38 to the right overhanging portion 17 at the same time. It acts in a dispersed manner at points to reduce impact and increase stability. Further, the bending moment acting on the base of the swinging member 26 is reduced because the right end of the holding portion 21 abuts against the stopper 38.
