Description

Door of forklift cabin

The present invention relates to a door of a forklift cabin, and more particularly, when the door of the forklift is opened and folded to minimize the gap in the folded state to prevent damage due to obstacle interference, and to simplify the installation structure when the locking device is damaged. It also relates to a door of a forklift cabin that can be easily repaired and used.

In general, the cab of a heavy-duty vehicle such as a forklift has a rectangular box-shaped cabin mounted on the upper part of the vehicle body to block the cab from rain and wind. A window is provided so that the cabin can be opened, and a door mounted on a hinge is opened and closed by an opening/closing device formed on the door handle on the side of the cabin so that the driver can get on and off the vehicle.

However, since the door mounted on the cabin opens at a maximum opening and closing angle of 180°, if the size of the door is made too large, the opening turning radius becomes too large, which is cumbersome to use. It should be prevented from being damaged due to the door being opened more than necessary.

Therefore, the door for the driver's entry and exit is formed with a very narrow width. Accordingly, a door is provided in which the driver can adjust the degree of opening and closing of the door as needed.

This two-door type door is divided into a fixed door and an open door, and a rotatably fixed door is installed on one side of the cabin (it may be installed separately and detachably from the cabin), and one side of the fixed door As a pivotable open door is installed on the hood, only open doors are normally used for forklift work or boarding and disembarking. do.

And the fixed door and the open door are equipped with locking devices, respectively. The locking device of the fixed door is provided to be locked in the cabin of the forklift, and the locking device of the open door is provided to be locked on the fixed door, so that the open door is opened and folded It is provided so that it can be temporarily fixed.

For example, as shown in FIG. 1, the shaft pin 1 is mounted on the outside of the fixed door 30a, and the holder 2 is mounted on the open door 30b so that the shaft pin 1 can be inserted. A structure in which the shaft pin 1 is inserted into the holder 2 when the open door 30b is opened is temporarily fixed by a locking means built into the holder 2 is mainly used.

However, in the conventional folding type door, both the structure for fixing the shaft pin and the structure for unlocking the locking device for fixing the open state of the open door must be built in, so the shaft pin 1 and the holder 2 are too far outward. Because of the structure that protrudes a lot, when the open door is locked to the fixed door in the fully opened state, the open door does not adhere to the fixed door as shown in FIG. 2, and the open door is kept in a lifted state from the fixed door there is

In other words, the forklift driver works while recognizing the width of the cabin as the vehicle width. When the open door is open, the open door and the fixed door do not come in close contact with each other and maintain a lifted state. In the process, there is a problem that it collides with a load or an obstacle.

However, when an open door is hit by a load or an obstacle on the edge of the open door in an open state, the impact is transmitted to the lock of the open door and the correct position is shifted.

That is, the locking device in which the shaft pin is inserted into the holder as described above is very difficult to assemble each part in the correct position. It is very cumbersome to work because it has to be assembled while adjusting the position. As above, if the correct position of the locking device is misaligned, the forklift driver has to send it back to a specialized manufacturer for repair because it is difficult to realign the locking device to the correct position.

In addition, when a load or obstacle is caught and an impact occurs on an open door, if the impact is severe, the impact is transmitted to the hinge of the open door as well as the open door as well as the fixed door, so there is a risk of twisting high, and in this case, partial repair is impossible and the door itself has to be replaced, so maintenance costs increase. Also, since the forklift itself cannot be used during the repair period, it is a very big loss in the industrial field.

On the other hand, the locking device fixed in the shaft manner as described above is configured to release the locking state by pressing the button 3 of the locking device linked to the outside of the forklift, that is, the shaft pin 2, in a state in which the open door is fully opened. In most cases, the forklift driver stays in the cabin, so in order to close the open door, the driver has to press the button on the rear of the forklift to close it after completely getting off the forklift, so it is very cumbersome to use.

The present invention is to solve the above problems, and by making the open door of the forklift door closely close to the fixed door in the fully opened state, damage to the door due to loads or obstacles even when driving or working with the door open The door lock structure is simplified so that assembly is possible, and even if the position of the lock device is misaligned, it is easy to adjust the correct position.

In addition, the forklift driver can unlock the unlocked door from the inside of the cabin room without getting off the forklift.

According to the present invention as a technical idea for achieving the above object, a door is mounted so as to be opened and closed in a cabin frame of a forklift by an opening and closing device, and the door is divided into a fixed door and an open door to be folded, and the door has a door. In the door of a forklift cabin provided with a locking device to fix the open/closed state of When the door is open, the locking rod and the locking rod are interlocked to each other to be locked, and a lever for unlocking the locking state of the locking rod is mounted on the inner surface where the locking rod is mounted to release the lock, and the locking rod is a bracket. The elevator has a built-in elevator in the receiving tube of the elevator, and as the elastic restoring force is applied by the elastic means, the vertical lifting operation of the elevator is made, and the elevator is engaged with the locking bar of the stopper and locked, or the elevator is locked from the locking bar by the operation of a lever. By disengaging and unlocking, the assembly structure is simplified, and the open door has a folding structure to maintain a state in close contact with the fixed door.

In addition, the fixed door is further provided with an auxiliary locking device for locking the fixed door to the cabin frame so that the door is locked in a double structure. When the door is closed, the auxiliary locking rod is engaged with the frame body of the cabin and locked to be locked, and a lever to unlock the auxiliary locking rod is installed in the lateral direction where the auxiliary locking rod is installed to release the lock from the inside of the cabin room. that the manipulation was made.

According to the door of the forklift cabin of the present invention, the spaced apart from the fixed door is minimized when the open door is fully opened and the closed state is maintained almost closely, even when driving or working with the door open. Since there is almost no difference from the outside diameter of the cabin, there is little risk of bumping into surrounding loads or obstacles under the driver's awareness.

In addition, even if the locking device is twisted due to impact caused by loads or obstacles, maintenance is possible simply by fine-tuning the mounting position of the stopper. There is no repair cost, and work delay and work downtime can be minimized.

In addition, since the locking device can be installed without damaging the frame body, such as performing piece work on the cabin, safety re-inspection is unnecessary due to damage to the vehicle body, and a structure for user convenience without loss of time or cost due to safety re-inspection Improvements are possible, which can greatly improve customer satisfaction.

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in FIG. 3 , the present invention provides a skeleton in which a cabin frame 20 that partitions the driver's boarding space is mounted on the forklift 10 upper portion, and the cabin frame is covered with windows to form a cabin room. It is possible to protect the driver from rain and wind and increase work efficiency while riding.

A door 30 is mounted on the side of the cabin 20 and an opening/closing device 40 is provided on the door 30 so that the driver can get on and off using the door 30, and the door 30 ) is composed of a fixed door 30a fixed to the cabin 20 and an open door 30b for the purpose of getting on and off.

That is, the door 30 is divided into a fixed door 30a and an open door 30b to be folded, and the door 30 is provided with a locking device to fix the open/closed state of the door. It is possible to determine whether to open or close by locking or unlocking the (30a) or the open door (30b).

The locking device includes a locking bar 100 that engages or releases a lock, a stop 200 that is an object of the locking table, and a lever 300 that operates whether to lock or unlock the locking table 100, and a lock It may be configured to include a stopper 400 that limits the proximity of the door when the device is locked.

4 is a view showing the structure of the locking device of the present invention, FIG. 5 is a view showing the structure of the locking base 100 and the lever 300, and FIGS. 6 to 8 are the structures in which the door is locked by the locking device. is a diagram showing

When described in more detail with reference to the drawings, in the present invention, a locking bar 100 is mounted on the outer surface of the fixed door 30a in a state in which it is divided into a fixed door 30a and an open door 30b, and the open door 30b) Mount the stopper (200).

The locking bar 100 and the stopper 200 are mounted to correspond to each other on surfaces that come into contact with the fixed door 30a in a state where the open door 30b is fully opened, and the locking bar 100 and the stopper 200 ) may be configured by swapping each other, but as will be described later, in order for the driver to perform the unlocking operation inside the cabin room, the locking bar 100 is mounted on the fixed door 30a, and the It is preferable to install the locking bar 200 so as to be locked.

And the inner surface of the fixed door 30a on which the locking stand 100 is mounted, that is, the inside of the fixed door 30a toward the inside of the cabin room, the locking state of the locking stand 100 exposed to the outside of the cabin room is operated to lock state A lever 300 for releasing can be mounted.

The lever 300 may be operated by the driver's manual operation or may be configured such that the unlock operation is performed by a separate button (not shown) in conjunction with an electronic device, but in the present invention, the driver manually A method of unlocking the lock state by manipulating it will be described.

On the other hand, in the locking table 100, the elevator 140 is built in the receiving tube 122 of the bracket 120, and the elastic restoring force is applied to the lifting platform by the elastic means 160 while the vertical lifting operation of the elevator is made. The elevator 140 is engaged with the locking bar 240 of the stopper 200 to be locked, or the lift 140 is separated from the locking bar 240 by the operation of the lever 300 to release the lock. can

The locking bar 100 has a latch head 142 in which the upper end of the lifting bar 140 is inclined to one side, and as shown in FIG. 240) while the lifting bar is elastically pressed and then restored, locking is performed.

At this time, the stopper 200 is bent or bent in a 'C' shape on the mounting plate 220 mounted on the outer surface of the door so as to protrude outward to have an inner mouth space 242. A hanging bar 240 is formed, and , while the latch head 142 of the elevator 140 is inserted into the internal space 242, it can be locked and fixed.

At this time, the mounting plate 220 is assembled to the door by a bolt method and is simply assembled. However, more preferably, it can be fixed so as not to flow by using the mounting frame of the opening and closing device to be described later.

That is, a plate material for reinforcing the door or mounting the opening and closing handle is embedded in the inner surface of the open door 30b. At this time, the mounting plate 220 is assembled in a bolt manner so that the clasp 200 does not flow by using the plate material. It can be configured, and when the position of the stopper 200 is misaligned, the position can be easily adjusted after loosening the bolt and adjusting the position again.

Therefore, as described above, since the lifting platform 140 is locked in a latch structure while moving up and down, it is configured to be installed even in a space where the interlocking distance between the locking table 100 and the locking table 200 is very narrow, as shown in FIG. As shown, since the width of the engaging portion of the lock is very narrow in a state in which the fixed door 30a and the open door 30b are folded, the open door 30b is horizontally close to the fixed door 30a and is very close. Folding is possible, and a locking device can be implemented within the separation width that can be generated by the hinge.

At this time, the locking bar 100 is mounted on the outer surface of the fixed door 30a, the stopper 200 is mounted on the outer surface of the open door 30b, respectively, and a lever for releasing the locking device on the inner surface of the fixed door 30a 300 is mounted to enable unlocking of the locking device inside the cabin room, and the lever 300 is linked with the lifting bar 140 to manually control the lifting operation of the lifting bar 140 to control the latch head 142 may be configured to release the state caught by the locking bar 240 and release the lock.

In addition, a receiving hole 32 is formed in the open door 30b as shown in FIG. 6 , and a buried mounting frame 34 having a recessed space is mounted in the receiving hole, and the door opening and closing device is installed in the buried type mounting frame 34 . By mounting the opening/closing handle 42 of (40), the opening/closing handle 42 may be configured to hardly protrude to the outside of the door or not to protrude at all.

And by preventing the opening/closing handle 42 from protruding to the side of the door in this way, when the fixed door 30a and the open door 30b are folded, interference by the opening and closing handle 42 does not occur and the fixed door and the open door are in close contact Folding state lock is made in the closed state.

At this time, the length of the opening and closing handle 42 protruding to the outside of the door is relatively shorter than the engagement interval between the locking bar 100 and the locking bar 200 in a state in which the fixed door and the open door are folded and in close contact. interference can be avoided.

The lever 300 is for controlling the locking state by changing the position of the elevator 140, and as shown in FIGS. 9 to 11, a movable part 320 for changing the position of the elevator 140 and the lever operation. The operation unit 340 for the is formed, the lever 300 by the operation shaft 360 may be mounted to be movable.

To this end, the bracket 120 may be provided with a lever mount 126 by welding or the like, and the lever 300 may be shaft-coupled by the operation shaft 360 to perform a rotation operation.

And the lifting platform 140 has an insertion portion 144 formed so that the movable portion 320 of the lever 300 can be inserted, and a slot hole 124 is formed in the receiving tube 122 of the bracket 120 to insert the movable portion. In a state in which the 320 penetrates the slot hole 124 and is inserted into the insertion unit 144, the lifting operation control of the elevator 140 is controlled by the operation of the lever 300 using the operation unit 340, and a locking means or auxiliary The unlocking of the locking means is performed.

That is, as shown in FIG. 12 , in the locked state of the locking device, the elevator 140 is caught and fixed to the locking bar 240 of the locking table 200 by the elastic restoring force of the elastic means 160 to maintain the locked state. In this state, when the movable part 320 is lifted by pulling the operation part 340 of the lever 300 in this state, the movable part 320 lifts the elevator 140 and the elevator 140 is caught by the locking bar 240 and is fixed. release, and the lock state is released.

In this case, the manipulation unit 340 may be configured with a cap made of an elastic material made of rubber or silicon having high frictional force in order to improve the driver's grip.

In addition, in the locked state of the open door 30b as described above, the open door 30b is fixed in close contact with the stopper 40 of the fixed door 30a. If it is made of rubber, when the locking state of the open door 30b is released by the elastic force of the rubber, the open door 30b is pushed out by the restoring force of the stopper 40 and the locked state is released.

At this time, the stopper 40 is formed to be relatively longer than the width between the fixed door 30a and the open door 30b in a folded state, so that when the open door 30b is folded, a buffer is made and at the same time as the open door When the folding state of (30b) is released, the locking state can be released by the repulsive force of the stopper 40, and the stopper 40 is formed of an elastic material such as rubber with a material of the tip portion and a spring therein. It can be formed to have a restoring force by further adding an elastic element such as.

On the other hand, the lifting bar 140 can be made of metal, high-strength plastic, or compressed rubber, preferably to prevent damage by the latch head 142 in the locked portion when the door 30 is opened and closed. For this purpose, it is preferable to make it with high-strength plastic or compressed rubber.

And when it is made of high-strength plastic, it can be made into a multi-layered plate-like structure to reduce costs, and by assembling in a multi-layered structure, maintenance costs can be reduced by replacing only the damaged parts even when parts are damaged.

And, by forming the plate in a multi-layered structure, as shown in FIG. 13, the cross section is different from each other, and the groove 146 is formed so that the elastic means 160 can be inserted into the plate located on the inner side except for the plate located at both ends. It may be configured to provide a simple assembly of the elastic means.

And at this time, the elastic means 160 makes only the diameter of a portion inserted into the groove 146 of the elevator 140 relatively small, and the diameter of the portion to which the remaining elastic restoring force is applied is formed to a diameter that can accommodate the entire elevator platform. While assembling is simplified, it is possible to prevent separation of the elastic means due to repeated operation, and it can be configured to achieve stable operation.

Meanwhile, the fixed door 30a may further include an auxiliary locking device for locking the fixed door 30a to the cabin 20 as shown in FIG. 14 .

The auxiliary locking device is mounted on the inner surface of the fixed door 30a, and the auxiliary locking rod 100-1 is mounted on the top or the bottom of the fixed door 30a so that the auxiliary locking rod 100-1 is in the closed state of the fixed door 30a. may be configured to engage and lock the frame tube body 22 of the cabin 20 .

In addition, a lever 300 for releasing the locking state of the auxiliary locking arm is mounted in the lateral direction in which the auxiliary locking arm 100-1 is mounted, so that the unlocking operation can be performed inside the cabin room.

In the auxiliary locking table 100-1, the elevator 140 is built in the receiving tube 122 of the bracket 120, and the vertical lifting operation of the elevator is performed while the elastic restoring force is applied to the elevator by the elastic means 160. It can be configured such that the elevator 140 engages and locks the frame tube body 22 of the cabin frame 20 as it goes down, and the locking state of the auxiliary locking platform is the elevator 140 by the driver's lever 300 operation. It can be configured to be released from the locking bar 240 to release the lock.
