DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tailgate fixing device for a vehicle bed.

(Prior Art) As a type of a tailgate fixing device for a vehicle carrier, as disclosed in Japanese Utility Model Laid-Open No. 59-105582, it is provided at the upper rear end of a side gate which constitutes a side wall of the vehicle carrier and is provided at the rear. Latch plate having a notch recess projecting upward and opening upward, a holder provided on a tailgate that constitutes the rear wall of the loading platform, a horizontally extending round rod-shaped shaft support portion, and a crosswise extension from the tip thereof. Approximately L, which has a handle portion and is axially movably and axially rotatably supported by the holder by a coaxial support portion to advance and retreat in the notch recess of the latch plate and engage and disengage with the latch plate. A hook that hooks the chain that holds the tailgate in a predetermined open state to the holder and a hook that is elastically abutted against the tip of the hook to release the chain that is hooked There is a tailgate fixing device for a vehicle bed for fixing a tailgate having a leaf spring that prevents the falling.

In this type of tailgate fixing device, in order to fix the tailgate to the sidegate, move the retracted handle to the side of the bed and advance it through the notch in the latch plate. This is done by rotating the handle downward to engage the base end portion of the handle portion of the handle with the outer surface of the latch plate. To unlock the tailgate from the side gate, rotate the handle that is engaged with the outer surface of the latch plate upward to release this engagement, and then remove the handle from the outside of the luggage carrier to the inside. Move to and retract from the notch in the latch plate.

On the other hand, the tailgate and the sidegate are attached to the side edges of the cargo bed at their lower edges so as to be able to rotate in the vertical direction, and when the tailgate is unfixed to the sidegate, the tailgate, or the gate and the sidegate. Is rotated downward so that the periphery of the loading platform is opened.

(Problems to be solved by the invention) By the way, in such a tailgate fixing device, the handle is not restricted in the vertical rotation direction when the tailgate is fixed, and the handle is rotated downward by its own weight. The handle is hanging down. For this reason, one side gate is erected and its front end is fixed to the front side of the vehicle body, then the tail gate is erected and one side is fixed to the rear end of the above side gate, and finally the other side gate. When the other side of the tailgate is fixed to the rear end of the tailgate, the lower end of the handle portion of the handle of the tailgate fixing device for fixing the other side of the tailgate projects forward from the standing position of the gate. In such a state, if the other side gate is rotated upward to stand up, the rear inside of the gate may collide with the lower end of the handle section immediately before the stand up and damage the handle section. .

Therefore, an object of the present invention is to effectively utilize the existing leaf spring of the tailgate in the tailgate fixing device of this type, and to rotate the handle of the tailgate fixing device by a predetermined rotation when the tailgate is unfixed. In order to be able to hold | maintain in a position, there exists in solving the said problem.

(Means for Solving the Problem) In order to solve the problem, the present invention provides a tailgate fixing device of the type described above, in which a part of the leaf spring is elastically abutted against the outer periphery of the shaft supporting portion of the handle. It is characterized in that it is formed in a contact shape, and a portion lower than the outer circumference of the contact portion is provided in a part of the outer circumference of the contact portion of the leaf spring in the coaxial support portion.

(Operation and effect of device) According to the tailgate fixing device configured as described above, the elastic force of the leaf spring with respect to the outer periphery of the shaft support portion of the handle is smaller at a portion lower than the outer periphery of the coaxial support portion and higher than the same portion. Great in. For this reason, when the handle rotates, it is necessary to give some extra turning force in order for the contact portion of the leaf spring to fit into the lower portion of the shaft support portion and then to pass over the same portion. Therefore, since the handle is restricted from rotating in the same portion and held in the same portion, the handle can be held in the predetermined rotating position at the time of unlocking by appropriately selecting the formation position of the portion. It is possible to avoid a collision between the side gate and the steering wheel when standing up.

In the tailgate fixing device, however, since the means for restricting the rotation of the handle is constituted by the handle itself and the existing leaf spring of the tailgate, the number of components of the tailgate fixing device may increase. In addition, the structure of the fixing device does not become complicated and its assembling does not become complicated.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.
1 to 3 show a left side portion of a tailgate having a tailgate fixing device according to the present invention. In the fixing device, the tailgate 11 is assembled at its lower end edge to the rear end side edge of the vehicle bed so as to be vertically rotatable, and has a top rail 11b at the upper end portion of its base plate 11a. The side posts 11c are provided at the side edges. The top rail 11b and the side posts 11c are formed in a hollow frame shape, and a holder constituting a fixing device is housed and welded to the left side portion of the rail 11b. The fixing device includes a latch plate 21, a holder 22, and a catch handle 23, and further includes a coil spring 24, an adjusting nut 25, a hook 26, and a leaf spring 27.

The latch plate 21 is fixed to the upper part of the rear end of the side gate 12 and protrudes rearward, and the inner side surface thereof faces the outer end surface of the tail gate 11 with a predetermined gap. The latch plate 21 has a notch recess 21a that opens upward and a guide surface 21b. The catch handle 23 is a substantially L-shaped one composed of a shaft support portion 23a and a handle portion 23b.
The shaft support portion 23a is axially slidably supported in the cylindrical portion 22a of the holder 22 so as to be slidable in the axial direction and rotatable in the circumferential direction.
Project from the side post 11c of the tailgate 11 to the outside. An adjusting nut 25 is screwed so as to be able to move forward and backward at the tip of the shaft supporting portion 23a of the handle 23, and the nut 25
A coil spring 24 is interposed between the inner wall 22b of the holder 22 and the inner wall 22b. Coil spring 24 is a catch handle 23
In the free state, the handle 23 is slid inward to the position shown by the chain double-dashed line in FIG. The hook 26 hooks the chain 13 that holds the tailgate 11 in a predetermined open state, and is fixed to the top rail 11b of the tailgate 11. Further, the leaf spring 27 has a function of retaining the chain 13 which is hooked, and is fixed to the rear wall 22c of the holder 22 as shown in FIG. Is in contact with.

As shown in FIGS. 1 and 4, the outer circumference of the shaft support 23a of the catch handle 23 is partially cut out into a flat recess 23c over a range longer than the maximum sliding length of the coaxial support 23a. The cylindrical portion 22a of the holder 22 corresponding to the recess 23c is partially cut out to form an opening 22d. Therefore, a part of the recess 23c of the catch handle 23 is exposed from the opening 22d of the tubular portion 22a.
On the other hand, the intermediate portion 27b of the leaf spring 27 has a flat plate shape that bulges forward by a predetermined amount. The intermediate bulging portion 27b is located at a position facing the opening 22d of the tubular portion 22a, and elastically abuts on the outer periphery of the handle shaft support 23a through the opening 22d with a predetermined repellency.

In the fixing device configured as described above, when the catch handle 23 is in the state shown by the solid line in FIGS. 1 to 3, the handle portion 23b of the handle 23 has the coil spring 2
The tailgate 11 is fixed to the side gate 12 by elastically engaging the outer surface of the latch plate 21 by the biasing force of 4. If the catch handle 23 in this state is rotated upward to the position shown by the chain double-dashed line in FIGS. 1 and 3 and pushed inward to the position shown by the chain double-dashed line in FIG. The fixation of 11 to the side gate 12 is released. As a result, both gates 11 and 12 can be rotated downward to open the periphery of the luggage carrier. Further, both the gates 11 and 12 are erected, and the catch handle 23 is pushed outward, contrary to the above, so that the inside of the notch recess 21a of the latch plate 21 is inserted outward, and then the handle 23 is opened. When rotated downward, the handle portion 23b of the handle 23 slides on the guide surface 21b of the latch plate 21 while sliding on the plate 21.
Engage with. As a result, the tail gate 11 is fixed to the side gate 12.

By the way, when all the gates that are rotating downwards are erected to enclose the periphery of the luggage carrier, one of both side gates is erected first and its front end is fixed to the front part of the vehicle body, and then the tailgate is attached. Stand up and fix one end to the rear end of the side gate, and finally stand up the other side gate to fix the front end to the front part of the vehicle body and at the rear end of the gate the other end of the tail gate. Often fixed. In this case, assuming that the other of the side gates is, for example, the side gate 12 of this embodiment, when the side gate 12 is rotated downward in the state where the tail gate 11 is raised, the catch handle 23 is rotated. If not regulated,
Due to its own weight, the handle 23 is positioned as shown by the three-dot chain line in FIG. 3, and the tip thereof may project forward from the tailgate 11.

However, in the present embodiment, when the intermediate bulging portion 27b of the leaf spring 27 is fitted into the recess 23c of the handle shaft support portion 23a, it acts to restrict the rotation of the coaxial support portion 23a. Therefore, when the rotation of the catch handle 23 is restricted and the lock is released, the catch handle 23 is held at the position shown by the solid line in FIG. 3 and does not project forward from the tailgate 11. Therefore, even if the side gate 12 is turned upright to stand up,
Does not collide with the catch handle 23 and damage the handle 23.

Further, according to the configuration of the present embodiment, the recess 23c of the catch handle 23 and the plate spring 27 constitute a means for restricting the rotation of the handle 23, and these two 23, 27 are existing components. Therefore, the number of constituent members of the fixing device is not increased, and the structure of the fixing device is not complicated and the assembly is not complicated at all.

FIG. 5 shows a modification of the leaf spring in the above embodiment. The leaf spring 28 of the modified example has a long main body 28a.
And an auxiliary portion 28b shorter than this. In the leaf spring 28, the lower end of the main body 28a is fixed to the holder 22, the tip of the main body 28a elastically abuts on the hook 26, and the tip of the auxiliary portion 28b is the outer circumference of the handle shaft support 23a. Is elastically abutted against. Therefore, the leaf spring 28 also has the action of restricting the rotation of the handle shaft support 23a, and has the same effect as the leaf spring 27. The catch handle 23 may be provided with recesses at a plurality of positions on the outer circumference of the coaxial support portion 23a so that the catch handle 23 is held at a plurality of rotational positions.
