DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tailgate stay attaching / detaching structure for a vehicle.

[0002]

2. Description of the Related Art Conventionally, as a tailgate stay attaching / detaching structure, as shown in FIG. 8, one end of a first link 21 is pivotally attached to a rear side body, not shown, and the other end of the first link 21 is attached to the other end. One end of the second link 22 is flexibly connected by a connecting shaft 23, and the other end of the second link 22 is provided with an elongated hole 24 serving as a locking portion, and the tailgate 20 is attached to the rear side body so as to be openable and closable. An oval head pin 26 on which the elongated hole 24 at the other end of the second link 22 is locked when the tail gate 20 is open
And the lock plate 25b of the tailgate 20 provided with the locking pieces 25c.

[0003]

In the above-mentioned conventional structure, the pin fixing plate 25a serving as a fixing seat of the oval head pin 26 is an integral structure with the lock plate 25b, which increases the manufacturing cost. Was. In addition, attaching and detaching the stay, that is, attaching and detaching the second link 22, requires a troublesome operation of inserting and removing the elongated hole 24 in phase with the oval head pin 26 in phase.

An object of the present invention is to simplify the structure for attaching and detaching a tailgate stay and to simplify the operation for attaching and detaching the stay.

[0005]

According to the present invention, there is provided a stay for connecting a rear side body of a vehicle to a tailgate to support an opening state of the tailgate. A stepped pin is provided at the tip of the stay on the side of the side stay, the stepped pin being provided with a Dharma-type engagement hole having a large diameter portion and a small diameter portion continuous with each other, and the side surface of the tailgate is engaged and disengaged. A restraining member is provided near the pin to prevent an edge of the locking portion locked to the stepped pin from abutting to prevent the locking portion from coming off.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 3, reference numeral 1 denotes a rear side body of the vehicle, and 2 in addition to FIGS. 1 and 2 denotes a tailgate, which is connected to the rear side body 1 by a hinge 3 so as to be openable and closable. Reference numeral 4 denotes a stay that connects the rear side body 1 and the tailgate 2 to support the open state of the tailgate 2. The stay 4 may be either a cable type or a link type. If the link type is used, the locking portion can be formed integrally, and if the cable type is used, a separate locking tool is fixed to the cable by caulking or the like.

At the tip of the stay 4 on the side of the tail gate 2, there is provided a locking member 5 having a Dharma-type engaging hole in which a large diameter portion 5a and a small diameter portion 5b are continuous. As shown in FIG. 3, the tip of the stay 4 on the side of the rear side body 1 is rotatably attached to the rear side body 1 by a pin 13 via an attachment 12.

A stepped pin 6 on which the locking member 5 is engaged and disengaged is provided on a side surface of the tailgate 2.
A restraining member 7 is provided in the vicinity of to prevent the locking tool 5 from coming off by contacting the edge of the locking tool 5 locked to the stepped pin 6. Although details of the restraining member 7 will be described later, the restraining member 7 also serves as a fixing seat for the stepped pin 6.

Reference numeral 9 denotes a lock plate, which is separate from the restraining member 7. As shown in FIG. 3, the lock plate 9 includes a locking piece 9a that engages with a lock receiving member 11 fixed to the rear side body 1 side.
A lock pin 10 provided on the tailgate 2 penetrates a locking piece 9 a engaged with the lock plate 9 and the lock receiving member 11 to lock the tailgate 2 to the rear side body 1.

A restraining member 7 for preventing the locking member 5 from coming off.
An example will be described. [Embodiment 1] As shown in FIGS. 4 and 5, a flat contact surface 7a on which an edge of a locking tool 5 locked on a stepped pin 6 contacts.
The flat contact surface 7a is provided with a detent protrusion 8 that engages with the side surface of the tailgate 2.

[Embodiment 2] As shown in FIG. 6 and FIG. 7, an arc contact surface 7b with which the edge of the locking tool 5 locked on the stepped pin 6 abuts is provided. A rotation preventing projection 8 that engages with the side surface of the tail gate 2 is provided at a portion 7b.

Since the present invention has the structure described above, the stay 4 can be detached from the large-diameter portion 5a of the locking member 5 by the stepped pin 6.
And the small diameter portion 5b is engaged with the small diameter shaft portion of the stepped pin 6. The operation of locking the small diameter portion 5b to the small diameter shaft portion of the stepped pin 6 is performed by inserting the large diameter portion 5a of the locking tool 5 through the large diameter head of the stepped pin 6 and then inserting the tailgate 2 into the tailgate 2. The small-diameter portion 5b is naturally locked to the small-diameter shaft portion of the stepped pin 6 by the opening gravity.

In the restraining member 7 according to the first embodiment, as shown in FIG. 5 from the vertical state in FIG. It comes into contact with the surface 7a to prevent the locking tool 5 from coming off.

Further, the stay 4 supports the open state of the tailgate 2 at an inclined angle with respect to the rear side body 1 by the above-described locking operation. At this time, as shown in FIG. 7, the locking member 5 is changed from the vertical state of FIG.
By rotating around the stepped pin 6, the edge of the locking tool 5 abuts against the arc contact surface 7 b of the restraining member 7 to prevent the locking tool 5 from coming off.

The action of preventing the locking member 5 from coming off is exerted on the flat contact surface 7a in the restraining member 7 of the first embodiment and on the arc contact surface 7b in the restraining member 7 of the second embodiment. The edge of the locking member 5 that rotates eccentrically around the stepped pin 6 is pressed against the large diameter portion 5a of the locking member 5 so that the small diameter portion 5b is locked to the stepped pin 6. Restricts movement.

Further, the locking member 5, which is restricted and restrained from moving toward the large-diameter portion 5 a by the restraining member 7 so as to secure the small-diameter portion 5 b to the stepped pin 6, secures the locking state. Since the small diameter portion 5b is engaged with the radial head, the locking member 5 prevents the stepped pin 6 from coming off in the axial direction and supports the open state of the tailgate 2.

In order to remove the locking tool 5 from the stepped pin 6, the stay 4 is set in a substantially vertical state as shown in FIGS. 4 and 6, and the large diameter portion 5a of the locking tool 5 and the large diameter of the stepped pin 6 are set. The parts may be matched and removed. In the second embodiment, the arc-shaped abutting surface 7b is provided on the restraining member 7, so that the state shown in FIG. 7 can be stably maintained without slipping when the locking tool 5 abuts.

[0018]

As described above, according to the present invention, one end of the stay is axially attached to the rear side body, and the other end on the side of the tailgate has a Dharma-type engagement hole in which a large diameter portion and a small diameter portion are continuous. A locking portion is provided, and a stepped pin on which the locking portion is disengaged from the side surface of the tailgate, and an edge of the locking portion locked to the stepped pin abuts the vicinity of the stepped pin so that the locking is performed. The locking member, which also serves as a fixing seat for the stepped pin, is a separate component separate from the lock plate, so that the structure is simplified and the manufacturing is simplified. Cost reduction is achieved. In addition, the locking portion is provided with a Dharma-shaped engaging hole having a continuous large-diameter portion and a small-diameter portion, so that the detaching operation with respect to the stepped pin can be easily and quickly obtained. Since the detachment of the part is prevented, there is an advantage that the opening state of the tailgate is safely and reliably supported.
