Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lock device for a side gate for a truck bed.

[Conventional technology]

BACKGROUND ART It is well known in the prior art to provide a locking device for locking a side gate on both sides of a loading platform so that the side gate does not open when the side gate is closed. This type of locking device has a hook protruding from a guard frame located in the front part of the loading platform, and an engaging piece having a notch is fixed to the front end part of the side gate, and when the side gate is closed, Engage the notch and the hook,
For example, locking means having an operating lever and a lock ring is used to prevent the hook and the notch from being separated from each other and to hold the side gate in the closed position (for example, the actual opening 56).
-102282 and Japanese Utility Model Laid-Open No. 62-95986).

By the way, when the truck is viewed from the front side thereof, the above-mentioned locking device is positioned so as to project outward from the side surface of the cab located in front of the luggage carrier. For this reason, when the side gate is closed, the engagement piece of the lock device is exposed to the outside, which may give a feeling of protrusion to the surrounding people.

Therefore, conventionally, the entire engaging piece is covered with a closing member made of a sheet metal so as to loosen the protrusion of the engaging piece so as not to cause discomfort to those around the user.

[Problems to be solved by the device]

However, since the above-mentioned closing body covers the entire engaging piece, its size increases, which not only causes an increase in weight of the truck but also inevitably causes a problem of increasing cost.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lock device for a side gate for a cargo bed that eliminates the above-mentioned conventional drawbacks, can reduce the feeling of protrusion of the engaging piece with a simple structure at low cost.

[Means for Solving the Problems]

In order to achieve the above object, the present invention is fixed to a hook projecting from a side surface of a guard frame located at a front portion of a loading platform and a front end of a side gate pivotally supported on a side portion of the loading platform. , An engagement piece having a notch with which the hook engages when the side gate is closed, and a lock that prevents disengagement of the notch and the hook when the hook engages and holds the side gate in the closed position In a locking device for a side gate of a truck for a truck, which is provided with a means, a locking pin having a cylindrical shape having a diameter larger than a plate thickness is fixedly provided at a front end portion of the engaging piece. A lock device is proposed in which a cover covering the whole is fitted to the pin.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3 showing an example of the track, 1
Is a loading platform located behind the cab 2, and a rear gate 3 is pivotally supported at the rear of the loading platform 1 and side gates 4 and 4a are pivotally supported at both sides thereof. A header board 6 is fixed to the front of the loading platform 1, and guard frames 7 are fixed to both sides of the header board 6, and the frame 7 forms a gate shape and forms a cab 2.
Located along the back panel of the.

When the side gate 4 is closed as shown in FIGS. 1 and 2, the rear part is locked to the rear gate 3 by a locking device (not shown), and the front part is fixed to the luggage carrier 1 by the locking device 5 according to the present invention. Locked.

The locking device 5, as clearly shown in FIGS. 4 and 5,
It has a hook 8 projecting from the side surface of the above-mentioned card frame 7 provided at the front part of the luggage carrier 1. An engaging piece 10 having a notch 9 is fixed to the front end of the side gate 4,
When the side gate 4 is closed, the hook 8 described above engages with the engaging piece 10.
Engages with the notch 9 of. At this time, the hooking means 11 can prevent the hook 8 and the notch 9 from coming off, and the side gate 4 can be held in the closed position as shown in FIGS. 4 and 5.

The locking means 11 shown as an example in the drawing is the guard frame 7
Support bracket 12 fixed to the side surface of the, and an operation lever pivotally supported on the bracket 12 via a pin 13.
14 and a lock ring 15 pivotally attached to the operation lever portion below the pin 13 so that the base end portion is rotatable.

4 and 5 show a state in which the side gate 4 is locked by the locking means 11. That is, the tip of the lock ring 15 is engaged with the tip of the hook 8 protruding outward from the notch 9, and the operating lever 14 is held at the position shown in FIG. As a result, the hook 8 and the notch 9 are prevented from coming off, and the side gate 4 is held in the closed position.

To unlock the side gate 4, the operation lever 13 may be rotated in the direction of arrow A, and the tip of the lock ring 15 may be removed from the hook 8. In this state, move the side gate 4 to the arrow B
When it is tilted in the direction, the hook 8 comes off the notch 9, and the side gate 4 can be opened as shown in FIG. The side gate 4 can be closed by the reverse operation. Regarding the structure and operation of the lock device 5 as described above, for example
It is disclosed in detail in Japanese Patent Laid-Open No. 102282.

By the way, when the truck is viewed from the front, as shown in FIG. 2, the locking device 5 is located in a state of protruding outward from the side surface of the cab 2. For this reason, as described above, the engaging piece 10 of the lock device 5 may give a feeling of protrusion to the surrounding people. In order to eliminate such inconvenience, in the past, as shown by the chain line in FIG.
10 and its surrounding parts were covered, but such a closed body
20 will increase the weight and cost of the truck.

Therefore, in the locking device 5 according to the present invention, as shown in FIGS. 4 and 5, the plate thickness t is provided at the front end of the engaging piece 10.
A cylindrical locking pin 16 having a larger diameter d is integrally fixed to the locking pin 16 by welding, for example.
For example, a cover 17 made of rubber or synthetic resin is fitted.

As shown in FIG. 5, the cover 17 is formed with a hole 18 having a shape that matches the shape of the engaging pin 16 and the engaging piece 10 in the vicinity thereof. And cover 17 while elastically deforming the cover 17 and pushing in the direction of arrow C.
Can be fitted to the locking pin 16. At this time, the locking pin 16 is aligned with the portion of the hole 18 having a corresponding shape, so that the cover 17 is prevented from coming off.

Since the locking pin 16 is entirely covered with the cover 17 as described above, the feeling of protrusion at the tip of the engaging piece 10 is alleviated, and it is possible to prevent the surrounding person from feeling uncomfortable. Moreover, since the cover 17 only covers the tip end portion of the engagement piece 10, the size can be reduced, the weight can be reduced as compared with the conventional closing body 20, and the cost can be reduced.

In addition, the cover 17 is protected from the impact when the side gate 4 is opened and closed.
Even if is disengaged from the locking pin 16 and the pin 16 is exposed, since the locking pin 16 itself has a cylindrical shape,
It is possible to prevent a person who sees this from giving an unpleasant protrusion feeling.

The example in which the present invention is applied to the lock device 5 for the one side gate 4 has been described above, but it goes without saying that the present invention can also be applied to the lock device for the other side gate 4a. Also, an example in which the engaging piece is formed with an inverted U-shaped notch is shown. However, as disclosed in another form, for example, Japanese Utility Model Laid-Open No. 62-95986, the engaging piece has a notch formed of a through hole. Even if it is formed, the present invention can be applied without any trouble.

[Effect of device]

According to the present invention, it is possible to reduce the feeling of protrusion of the locking device with respect to the engaging piece with a simple structure, and it is possible to suppress an increase in cost and weight.
