Description

{DOOR SURPORT DEVICE FOR FREIGHT CAR}

The present invention relates to a loading door fixing device capable of safely opening a door hingedly installed at a rear end of a loading car in a loading car, until the loading and unloading of the cargo is completed.

At the rear end of the cargo hold, there is a hinged top hinged door on each side door. The car is closed every time the cargo is loaded or unloaded. This is not the case if the closed door is locked, but you should be careful about the safety of the vehicle when the door is open, as it can cause injuries to drivers, tides, passengers, and other vehicles around the stopped top. The door of the open loader is arranged in the forward and backward direction of the loader, so that the opening of the loader at the obtuse angle from the rear end of the loader is effective to prevent unintentional damage caused by the opened loader door.

Prior arts for securing the loading door to prevent it from being opened by an obtuse angle are disclosed in Published Patent Application No. 2011-0114855, Publication No. 2013-0063450, and Registration Practical Model No. 459020.

A first fixing member attached to a rear end of the inner wall of the loading box, a chain type connecting link connected to the first fixing member at a front end thereof, and a second connecting member attached to the inner surface of the door at a height equal to that of the first fixing member, It is inconvenient for the second stationary member of the open door to be hooked and unfastened by inserting the free end of the linking ring into the second hooking member of the second stationary member.

In addition, when the door is closed and locked, the hanging connection ring collides with the inner surface of the loading box to generate noise, and the load and the connecting hook are damaged due to the friction at that time. To replace the problem hooking connection, It is cumbersome because it is premised.

A pin holder having a pin hole drilled radially on a hinge for supporting the door is mounted on the hinge for supporting the door, and a pin inserted into a pin hole of the pin holder, The housing is attached, and the fixing pin is pressurized downward by the elastic body loaded on the top of the pin housing.

This prior art has the advantage of being able to arbitrarily select the opening angle of the door, while it has a pin holder, a bracket used for fixing it to the door, a slide groove for locking state maintenance guidance of a handle projecting sideways from the pin Since the number of parts is large from the pin housing to the elastic body for posture stabilization of the fixing pin, the manufacturing difficulty is high and it is also not suitable for installation in the loading box.

Further, it is difficult to replace the pin housing and the pin housing welded to the edge of the door adjacent thereto, and it is difficult to replace the fixing pin trapped in the pin housing. Replacement of the pin holder welded on the hinge is even more difficult. In addition, when the angle of the open door is limited, the door can be closed only by removing the fastener inserted in the pin holder, and the door can not be closed without such prior operation.

In the latter case, one end of the fixing member is mounted on a support member attached to the inner rear end of the loading box and is rotatable in place around the pin, and is attached to the inner surface of the door close to the hinge, And a locking member that locks the free end of the member in a pod-fitting manner to fix the open door at a right angle.

In this prior art, the free member is released from the engagement member, and when the user releases the hand, the fixing member is sagged downward by gravity. When the door is closed and locked in this way, the stationary member hanging down and the stationary member are damaged when the stationary member is rocked.

As in the case of the core, the door is not closed without releasing the free end of the fastening member caught by the fastening member in a state where the angle of the open door is limited, and there is an inconvenience to unscrew the fastening member to replace the fastening member fastened to the support member.

The present invention relates to a loading device for a top loading vehicle which is capable of limiting a door opening angle within a range in which a door is opened side by side on a side surface of a loading box, and when the door opening angle is released, And it is an object of the present invention to provide a load-carrying door fixing device for a to-be-loaded vehicle, in which the inner surface of the load-carrying box and the latch are protected.

The above object can be attained by providing a hanger support having a stopper attached to a doorpost of a loading box to support the hanger in place so that the hanger can rotate in place, A horizontal guide attached to a height equal to the height of the hanger support so as to limit the angle of opening of the hanger by interrupting the front end of the hanger, can do.

Opening and Closing the Door at an Acute Angle The door, which was opened with the tap in the horizontal guide lowered to the side of the door, then the door touched to the rear end of the horizontal guide was hooked When the door is closed in this state, the door of the hanger can be moved to the outer end of the horizontal guide, and the door can be locked by being closed. Therefore, there is no need to operate the hanger when closing the door.

If the tap is running on the outer edge of the horizontal guide or the tap is pulled out from the horizontal guide, it is turned toward the loading side and the tap is closed. When the clasp is pushed down, the hanger does not rock. No sound, no fear of damage due to mutual friction.

It is also very easy to replace the broken hanger by pulling the hanger up so that the axle and the faucet can easily be removed from the hanger support, the pad or the horizontal guide.

As compared with the other prior arts described above, the structure is simple, so that it is easy to manufacture, to attach to a loading box, to restrict the opening angle, and to release the opening angle limitation.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.
Fig. 2 is a cross-
Fig. 3 is an example of a case in which the front end of the latch is trapped at the rear end of the horizontal guide of the open door,
Fig. 4 is an example of a case in which the door is closed as it is in the state of Fig. 3

The loader door fixing device for a toll vehicle according to the present invention comprises a hanger (1) for limiting a door opening angle in cooperation with a horizontal guide and a hanger (1) for supporting the hanger (1) (3) which is attached to the earth (2) at a height equal to the height of the rear part of the hanger support (2) in the loading compartment and is inserted into the rest of the hanger (1) And a horizontal guide 4 which is attached at a height equal to that of the support 2 and guides the tip of the hanger 1 when the door is closed.

The hook 1 is a small-diameter metal pipe or a small-diameter steel bar, the base end of which is a shaft 5 which is fitted in the shaft hole of the hook- There is a nipple 6 which is bent in the same direction as the shaft 5 so as to allow the nipple 3 or the horizontal guide 4 to fall loose.

The hanger support 2 is attached to the door frame of the loading box and is a hinge replacement for supporting the hanger 1 in place.

The closure cap (3) is to prevent the rocker (1) from rocking during operation by inserting the cock (6) down when not using the hanger (1).
