JPH0986180A - Rear door hinge structure of truck - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a rear door hinge structure having a hinge not seen from the outside and good appearance by providing hinge parts for interconnecting shaft pin supporting parts fixed to the side wall rear ends of an end edge and a load room respectively with shaft pins and covering members for covering both shaft supporting parts, the shaft pins and the hinge parts in a door. SOLUTION: First shat pin supporting parts 12 are fixed to the end part side edge of a door 10, second shaft pin supporting parts 18 are fixed to the side wall 16 rear part side edge of the load room of a truck and hinge parts 24 for interconnecting both shaft pin supporting parts 12 and 18 via shaft pins 20 and 22 so as to be freely rotated are provided. When the door 10 is rotated about 90 deg. with the second shaft 22 as an axis, the door is temporarily stopped by a stopping member 28 and then rotated up to 180 deg. by switching a rotary shaft to the shaft pin 20 and then further rotated up to 270 deg.. A cover part 30 for covering the first shaft pin supporting parts 12 and the first shaft pin 20 and a cover part 32 for covering the second shaft pin supporting parts 18 and the second shaft pin 22 are extended to the door 10 and the side wall 16.

Detailed Description of the Invention

[0001]

The present invention relates to a van type vehicle, a wing type vehicle,
The present invention relates to a hinged structure of a rear door of a freight vehicle such as a guannon type door.

[0002]

2. Description of the Related Art Kannon-type doors in which left and right door edges are rotatably attached to the left and right columns of a rear door frame of a freight vehicle through hinges are widely used. As shown in FIG. 3, a shaft pin support component (hinge butt) B is provided on the rear surface of the left and right corner posts C of the rear door frame, and the hinge H is attached to the end of the rear surface of the door D.
The hinge H and the shaft pin support component B are pivotally attached to each other via the shaft pin P, but the door D is housed inside the door frame, and left and right of the door frame. Since the corner post C also has a width dimension and the door D needs to rotate 270 ° around the shaft pin P, the center of rotation of the shaft pin P is necessarily equivalent to the rear surface of the corner post C. It is necessary to project to the above, and it is also necessary to use the method described in JP-A-6-42253, JP-A-6-2784.
Like 67, a combination of aluminum extruded mold materials has a problem that an aluminum hinge, a hinge slip prevention member, and a cutout line for slip prevention can be seen from the outside, and a line of the aluminum mold material combination goes out. As in the case of 3-61489, a hidden hinge with a corner cover attached to this hinge has a problem that lines (gaps) appear at both ends of the corner cover. Some of them use a one-sided rubber hinge, but there is a problem that the hinge can be seen from the outside.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to cover a hinge part, which is a turning device, almost completely with a cover member when a rear door of a freight car is closed, and to provide a gap on the lateral side. It is an object of the present invention to provide a hinge structure for a rear door of a lorry that has a very smart appearance in which lines can be seen.

[0004]

In order to achieve the above object, a first shaft pin supporting component is fixed to an end edge of a door and a second shaft pin supporting component is fixed to a rear end of a side wall of a luggage compartment. And a hinge component that rotatably connects the first and second shaft pin support components via the first and second shaft pins, respectively, and the second shaft pin is outwardly moved by a spring member. The door is urged and supported to rotate, and when the door is opened, when the door rotates about the second shaft pin to an open position of about 90 °, the second door is opened.
The second stop member fixed to the shaft pin support component of the above switches the rotary shaft to the first shaft pin, and the rotation shaft is changed to about 270.
When the door comes to a position of about 90 ° when the door is rotated up to 90 ° and the door is closed, the rotary shaft is rotated by the first stop member fixed to the first shaft pin supporting component. The door is rotated until the door is closed and the first and second doors are rotated.
And a cover member for covering the first and second shaft pins and the hinge part, and a hinge structure for a rear door of a freight vehicle.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view in which a part of an arrow AA in FIG. 2 is cut away, and FIG. FIG. 3 is a perspective view of an entire freight vehicle, FIG. 3 shows a structure of a hinge portion of a gannon door that has been widely used in the past, and FIG. 4 shows A of FIG.
Fig. 5 (a) shows a state where the door is opened 90 °, Fig. 5 (b) shows a state where the door is opened 180 °, and Fig. 5 (c) shows a door 270 °. FIG. 6 shows an opened state, and FIG. 6 shows another embodiment of the present invention.

As shown in FIGS. 1 to 5, a first shaft pin support component (hinge butt) 12 is fixed to an end side edge of a door 10 and a rear end edge of a side wall 16 of a luggage compartment 14 of a freight vehicle. A second shaft pin support component (hinge butt) 18 is fixedly attached to the first and second shaft pin support components 12 and 18, and the first and second shaft pin support components 12 and 18 are rotatable via the first and second shaft pins 20 and 22, respectively. The second shaft pin 22 is supported by a torsion coil spring 26 so as to rotate outward (clockwise in FIG. 4) by a torsion coil spring 26.
6 urges the hinge part 24 to rotate outward from the closed position until it hits the stop member 28, so that the door 10
The stop member 29 and the first shaft pin support member 12 are always in contact with each other from the closed state to the 90 ° open state, and do not rotate about the first shaft pin. Therefore, as shown in FIG. As shown, the door pivots about the second axle pin 22 for about 9
When it is rotated by 0 °, it is stopped by the stop member 28, and as shown in FIGS. 4B and 4C, the rotation shaft is switched to the first shaft pin 20 and rotated up to 180 °. And further rotate to about 270 °.

Further, an end edge of the rear plate of the door 10 is extended in an arc shape to form a cover portion 30 having an arc-shaped cross section, which covers the first shaft pin support component 12 and the first shaft pin 20. The side wall of the side wall 16 is further extended to form the second side wall.
Which covers the shaft pin support component 18 and the second shaft pin 22 of
It forms part 32.

Next, contrary to the above, the door 10 is pivoted about the first shaft pin 20 toward the closing direction, and when the opening angle reaches the position of 90 °, the first shaft pin support component 12 is stopped. Member 2
9 and thereafter rotates about the second shaft pin 22 as an axis so that the inner end of the door 10 contacts the cushioning member 34, and at the same time, the cover portion 30 having an arcuate cross section also rotates. And the edge is close to the edge of the cover portion 32.

As a result, when the rear door of the freight car is closed, the hinge part, which is the turning device, is almost completely covered with the cover member, and a single line of a gap is visible on the lateral side. The hinged structure of the rear door of a smart freight car.

FIG. 6 shows another embodiment of the present invention. In this embodiment, instead of the cover portion 30 having an arcuate cross section, a cross section L is formed.
A cover portion 36 having a character shape is used.

[0011]

As described above, according to the present invention, the hinge part, the shaft pin support part (hinge butt), the shaft pin, etc., which is the hinge device of the rear door of the freight car, is almost completely covered.
It is housed inside the member, so that one line of the gap can be seen on the lateral side, the appearance is very smart, and although one rotating pin has two rotating parts, one shaft pin is a spring. The hinge structure is stable because it is supported by a member so as to rotate outward.
