Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement of a cab lock device for fixing a tilt cab of a vehicle.

[Prior Art] Vehicles equipped with a tilting cab require a cab lock device for fixing the cab. This cab lock device is equipped with a guide mechanism for guiding the cab to a fixed position, but heretofore, this guide mechanism has been provided separately and close to the lock device.

4 to 6 show a conventional device, in which a lock pin 2 and a guide pin 3 are provided at the lower part of the back of the cab 1. On the other hand, a cab mount 10 attached to the frame of the vehicle has a cab locking device 11 and a rubber member 12 which also serves as a guide. A spring 15 is inserted into the cab mount to provide a cushion. As shown in detail in FIG. 6, a guide plate 16 having a tapered hole is provided on the upper part of the rubber member 12, and the lower surface of the rubber member 12 is attached to the mount 10 via a seat plate 17.

When the cab 1 is lowered from the inclined state to the normal position, the guide pin 3 is guided by the tapered hole of the guide plate 16 and inserted into the hole 13 as shown in FIG. 5, thereby guiding the cab 1 to the normal position. .

As a result, the lock pin 2 on the cab side engages with the cab block 11, and the cab 1 is fixed to the mount 10.

As described above, in the conventional device, it was necessary to provide the lock mechanism and the guide mechanism separately, and the guide mechanism required three members: a guide plate, a rubber, and a seat plate.

The present applicant proposed an improvement to the guide device in Japanese Utility Model Application Publication No. 60-20977, but this proposal also did not integrate the lock device and the guide device.

[Object of the invention] An object of the invention is to provide a cablock device incorporating a guide device.

[Structure of the invention] The guide-cum-cab-lock device of the present invention includes a cab-block device attached to the cab side of the vehicle, and a lock pin bracket attached to the mount side of the frame of the vehicle body, and the cab-block device is mounted in the center. The lock pin bracket has a tapered surface on its upper surface, and a V-shaped guide provided on both sides of the lock device, and a guide plate formed on the guide side end. It has a rubber member with a V-shaped groove that is attached between the two sides.

[Explanation of function and effect] Therefore, when the cab is kicked down, the guide comes into contact with the tapered surface of the lock pin bracket and is approximately centered, and furthermore, the guide matches the V-groove of the rubber member and is completely centered. positioning is possible. In this device, the guide and locking device are integrated, so the mounting position can be freely selected, and the structure is simple, making adjustment and maintenance easy.

[Example] An example of the present invention will be described using FIGS. 1 to 3.

A cab lock device 20 attached to the lower rear of the cab 1 is equipped with a lock device 21 of a known type inside. A pair of guides 22 are provided at the lower end of the cab lock device 20, sandwiching the lock device. This guide 22 has a V-shaped portion 24 and a guide plate 23 formed by bending the end portion.
On the other hand, the upper end surface of a lock pin bracket 30 attached to the mount side of the vehicle body frame is formed into a tapered surface 32, and a lock pin 33 is attached between the brackets 30. A rubber member 35 is attached to the seat plate 31 with the lock pin 33 interposed therebetween.

A V-shaped groove 36 is formed in the center of the upper surface of the rubber member 35. A cushion spring 15 is arranged at the bottom of the seat plate to which the rubber member is attached. When the cab 1 is lowered, the guide plate 23 of the guide 22 comes into contact with the upper end tapered surface 32 of the lock pin bracket, and the cab 1 is roughly centered. At this time, the width ^l- of the guide plate 23 is made smaller than the width l of the lock pin bracket.

The guide 22 that has completed centering has its V
The shaped portion 24 engages with the V-groove 36 of the rubber member 35. At the same time, the locking device 21 engages the locking pin 33 to complete the locking.

[Summary] As described above, the present invention integrates the lock mechanism and guide mechanism of the cab lock device into one unit, thereby reducing the number of parts and reducing costs.

Furthermore, since the locking device is placed on the cab side, the installation space is small and the degree of freedom in the installation position is increased. Therefore, the locking mechanism can be easily adjusted and maintained.
