Description

[Detailed Description of the Invention] The present invention relates to a hinge structure for a rotatably opened/closed seat provided in a two-wheeled vehicle such as a motorcycle.

Generally, some seats installed in two-wheeled vehicles such as motorcycles are rotatable laterally to open and close a storage space formed by a tail section.

As shown in FIG. 4, the hinge structure of this opening/closing seat is such that a locking device C having a cylindrical support at one end is fixed to the vehicle body frame a, and a locking device C having a cylindrical support at one end is fixed to the bottom surface of the opening/closing seat (not shown). A connecting metal fitting e having both sides d bent downward so as to sandwich the support part is fixed, a pin hole f is bored in both side parts d of the connecting metal fitting e, and the lower end thereof is further bent inward. A stopper part g is formed, and the locking tool C and the connecting metal fitting e are connected by an engaging shaft, and a split pin j is applied to a pin hole i of the engaging shaft to prevent removal. It is said that

However, with this hinge structure, when installing the opening/closing seat, the engagement shaft must be inserted with the pin hole f aligned with the hole in the support part, making it extremely difficult to work in a narrow space. It was complicated.

In addition, with this hinge structure, even when the opening/closing seat is locked, it is possible to remove the cotter pin j and pull out the engagement shaft, and the opening/closing seat can be opened even when the opening/closing seat is locked, saving storage space. There were drawbacks such as items inside being stolen.

In view of these points, the present invention reduces the number of parts by integrally molding the conventional connecting fitting and the engagement shaft, and can be easily installed by simply sliding the opening/closing sheet. To provide an opening/closing sheet type hinge structure in which a connecting fitting and a locking fitting cannot be released.

Hereinafter, the configuration of the present invention will be explained based on examples.

In Figures 1 and 2, reference numeral 1 denotes an opening/closing seat installed in a two-wheeled vehicle such as a Natobai, which is rotatably installed laterally to open and close a storage space formed in the tail section. There is.

The hinge structure of the opening/closing seat 1 is such that a hinge receiver 2 is fixed to the opening/closing seat 1, a connecting fitting 4 is fixed to the pipe-shaped vehicle body frame 3, and the hinge receiver is formed by connecting the fitting 2 and the connecting fitting 4. has been done.

The hinge receiver 2 is a pipe-shaped hinge receiver with a slight cut-shaped gap provided at its lower end, and consists of a portion 5 and a mounting portion 6, both of which are welded to form an L-shape. It is fixedly installed on the lower surface of the opening/closing sheet 1.

On the other hand, the connecting fitting 4 includes a cylindrical and hollow hinge portion 7;
The hinge receiver of the tool 2 consists of a web part 9 having an opening 8 into which the part 5 can be inserted, and a mounting part 10, and these three parts are successively formed in this order into a ■-shape from one sheet metal. and is fixed to the vehicle body frame 3.

The outer diameter of the hinge part 7 is 7 mm when the sheet metal thickness is 1.6 mrn, and 10 mm when the plate thickness is 23 mm. The hinge part 1 is passed through the gap and fitted into the hinge receiver part 5, so that the hinge receiver is connected to the tool 2, and the hinge receiver part 5 is connected to the opening part 8.
It is configured to rotate.

In addition, if the hinge part 7 of the connecting fitting 4 is formed into an elliptical cylinder shape,
While maintaining the same function as in the case of the cylindrical hinge part 7,
The hinge receiver has the advantage that the hinge part 7 can be easily inserted into the part 5.

In addition, as shown in FIG. 3, the hinge receiver of the tool 2 is provided with a stopper part 11 together with the hinge receiver part 5, and the stopper part 11 abuts against the web part 9. It is also possible to hold the open/close seat 1 in an appropriate open state.

Therefore, when attaching the opening/closing seat 1 to the vehicle body frame 3, the opening/closing seat 1 is slid so that the web part 9 of the connecting fitting 4 passes through the gap in the hinge receiving part 5 of the hinge holder 2, and the opening/closing seat 1 is attached to the hinge part. When the hinge receiver 1 is engaged with the portion 5 (dashed line in FIG. 1), and the hinge receiver is rotated so that the portion 5 is inserted into the opening 8, the opening/closing seat 1 is closed (solid line in FIG. 1). The hinge part 7 is securely attached to the hinge receiver part 5 without coming off from the hinge part 5.

In addition, when opening the opening/closing seat 1, the hinge receiver should be
It can be opened by rotating it in the opposite direction to the above-mentioned installation so that it is inserted into the opening 8. Furthermore, if the stopper part 11 is provided on the hinge receiver 2, the stopper part 11 can be opened.
comes into contact with the web portion 9, and the opening/closing sheet 1 is held in an appropriate open position (double-dashed line in FIG. 1).

When removing the opening/closing seat 1, the above-mentioned installation of the opening/closing seat 1 can be performed in the reverse order, and the opening/closing seat 1 is slid with the hinge receiver portion 5 aligned with the web portion 9, and the hinge The portion 7 and the hinge receiver can be removed by releasing the engagement with the portion 5.

In the present invention, as described above, the hinge part is integrally formed on the connecting fitting, and the hinge part is engaged with the hinge receiver, so that the opening/closing sheet can be attached to the hinge receiver of the fitting. You can install it by simply sliding it along the
The work becomes very simple, and the number of parts is small because no engaging shaft, split pin, etc. are required, so the manufacturing cost is reduced.

Furthermore, when the door is closed and locked, the hinge portion and the hinge receiver cannot be disengaged from each other, so that the open/close sheet can be securely secured.

In addition, while the hinge part is provided on the vehicle frame side, the hinge part, which has a shape that easily deforms due to external factors during manufacturing, is provided on the opening/closing seat side, so if the hinge part becomes deformed, it cannot be replaced. It has the advantage of being easy to perform.
