Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fender lock device for a construction vehicle that locks a fender that is openably and closably mounted on top of wheels.

[0002]

[Prior art]

 In a conventional wheeled construction vehicle such as a wheel loader, a fender b is provided above a wheel a as shown in FIG. The fender b is composed of a rear fender c and a full fender d, and the full fender d is attached to a door f that is openably and closably provided on a side surface of an engine compartment e so that it can be opened and closed in the vertical direction together with the door f. ing.

A latch g as shown in FIG. 2 and a latch h as shown in FIG. 3 are provided between the rear fender c and the full fender d. The latch g shown in FIG. 2 is formed of a latch j and a hook k. By hooking the latch j on the hook k, the rear fender c and the full fender d are locked, and the latch j is raised to raise the hook k. The lock can be released by further removing it.

On the other hand, the latch h shown in FIG. 3 has a hook-shaped catcher n which is biased by a spring m, and when this catcher n engages with a stopper o on the fender c side, the fender c and the full fender are engaged. The space between d is locked, and the lock can be released by removing the catcher n from the stopper o by the handle p.

[0005]

[Problems to be solved by the device]

 However, in the former latch g, since the rear fender c and the full fender d are locked in the front-rear direction, the locking force in the up-down direction is weak. Therefore, when a vertical force acts on the fender b, it easily disengages, and the engine compartment When closing the door f of e, there was a problem that the latch g was damaged by interfering with the hook k when the latch j was in the down state.

In addition, the latter latch h has to be opened when the door f of the engine compartment e is opened, so that the handle p must be pulled to remove the catcher n from the stopper o while opening the door f. there were. The present invention has been made in order to improve such a problem, and an object thereof is to provide a fender lock device for a construction vehicle that is easy to operate and that can reliably lock the fender.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides fenders on both sides of an engine compartment provided at the rear of the vehicle body so as to cover above the wheels, and a rear fender having the fender attached to the vehicle body side and an engine compartment. In a construction vehicle consisting of a full fender attached to a door that can be opened and closed in the vertical direction on the side of the vehicle, one of the rear fender and full fender has a catcher that can be rotated by a handle provided on the upper surface of the fender. On the other hand, a striker with which the catcher is removably engaged is provided, and the catcher is biased in the locking direction and the unlocking direction by a reversible toggle spring.

[0008]

[Action]

 With the above configuration, the door of the engine compartment can be opened while the catcher is held in the unlocked position, which improves operability.

[0009]

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings shown in FIG. In FIG. 4, reference numeral 1 denotes a vehicle body of a construction vehicle, an engine compartment 2 is provided at a rear portion thereof, and fenders 4 are provided on both sides of the engine compartment 2 so as to cover upper portions of wheels 3. The fender 4 is composed of rear fenders 4a attached to both sides of the vehicle body 1 and a full fender 4b attached to a door 2a provided on the side surface of the engine compartment 2 so as to be vertically openable and closable. The locking device 6 of the present invention is provided between them.

As shown in FIG. 5 and subsequent figures, the locking device 6 has a catcher 9 rotatably supported by a bracket 7 fixed to the inside of the full fender 4b via a support shaft 8. The catcher 9 is in the shape of a hook having a notch 9a for engaging a striker 10 which will be described later, and one end of a plate 9b which is flush with the upper surface of the full fender 4b when locked is fixed to a part of the catcher 9. . The plate 9b is provided so as to close the square hole 4c opened on the upper surface of the full fender 4b, and the handle 9c is fixed to the other end thereof.

Further, one end of a toggle bar 13 is attached to a plate 9d fixed to the plate 9b side of the catcher 9. The other end of the toggle spring 13 is attached to a bracket 7 at the rear of the catcher 9 via a pin 14 so that the toggle spring 13 holds the catcher 9 in the locked position and the unlocked position. There is.

On the other hand, inside the rear fender 4a, a bracket 16 is provided so as to protrude below the full fender 4b, and the striker 10 is fixed to the tip of the bracket 16. The striker 10 is formed in a substantially U shape by a round bar, and is fixed to the bracket 16 by a mounting plate 10a. When the full fender 4b is closed, the notch 9a of the catcher 9 provided on the full fender 4b side. Are engaged.

Next, the operation will be described. When the door 2a of the engine compartment 2 is closed, the catcher 9 provided on the full fender 4b side is provided to the striker 10 on the rear fender 4a side as shown by the solid line in FIG. The catcher 9 is engaged and locked between the rear fender 4a and the full fender 4b, and the catcher 9 is urged in the locking direction by the toggle spring 13. Therefore, the catcher 9 may strike the striker 10 due to vibrations or the like acting on the fender 4 during traveling. It's never too far off.

Next, when inspecting or servicing the inside of the engine room 2, first, the handle 9c is pulled and the catcher 9 is rotated about the support shaft 8 to the imaginary line position shown in FIG. As a result, the catcher 9 is disengaged from the striker 10 to be unlocked and the toggle spring 13 is reversed so as to urge the catcher 9 in the unlocking direction over the support shaft 8, so that the catcher 9c is released even if the handle 9c is released. 9 is held in the unlocked position. As a result, the door 2a can be opened and closed with the handle 9c separated, so that the operability is improved. Also, even if the door 2a is closed without knowing that the plate 9b has fallen down during the inspection and maintenance work and the catcher 9 is locked, the striker 10 rotates the catcher 9 to return it to the locked state. There is no worry that the striker 10 will be damaged.

[0015]

[Effect of device]

 As described in detail above, this invention is provided with a catcher rotatable on one of the rear fender and the full fender to a locked and unlocked position by a handle, and on the other side with a striker with which the catcher engages. Since it is urged in the lock direction and the unlock direction by a toggle spring, when opening the door of the engine room, the door can be opened while the catcher is held in the unlock position, and operability is improved.

Even if the door is closed without knowing that the catcher is in the locked position while the door is open, no excessive force is applied to the catcher or striker, so that they will not be damaged and the fender will not be damaged. Even if a vertical force is applied due to vibration during driving, the catcher does not have to come off the striker. Furthermore, since the handle is provided on the top side of the fender, the dirt and sand that the wheels splashed up will not adhere, and since the catcher and striker are provided inside the fender, the appearance of the entire fender may be impaired. Absent.
