JPH026280A - Box type truck having opening/closing door on whole face of rear and both side face - Google Patents

Abstract

PURPOSE:To enable the loading/unloading of a load by opening the door on a necessary place by providing doors which can be fully opened on the whole of both right/left sides and the rear of the load box of a truck. CONSTITUTION:Four doors 3-6 are openably/closably provided with hinges 7-10 on each of the right/left sides of the load box of a truck, while a door is openably/closably provided with hinges on the rear portion of the load box. The loading/unloading of a load is carried by appropreately opening a necessary door and by means of a fork lift, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION (al) Industrial Application Field By using the box type of the present invention, loading and unloading of cargo can be carried out easily.
Since the box can be opened on three sides, the cargo can be loaded freely at the desired destination, unlike the conventional method, which required the vehicle to be moved forward, backward, or rotated depending on the site situation. This eliminates the inconvenience of using a forklift, making it especially convenient for pallet loading using a forklift.It also makes it easier to load and unload cargo, and it also makes it easier to clean the inside of the box, making it easier to keep the inside of the box clean at all times. In addition, if there are volatile or toxic vaporized substances in the cargo, which sometimes occurs at present, these gases may be trapped in the box, or dry ice, etc. The danger of injury to the human body due to lack of oxygen, etc., which occurs when cargo is loaded, can be completely opened, allowing for better ventilation and preventing the temperature inside the box from rising. It has the advantage of being able to.

(bl) Conventional technology In the case of conventional box-type large trucks, the cargo bed door is provided only at the rear of the box, and the rear door of the box allows cargo loaded by a forklift to be carried all the way to the front of the box. Loading and unloading had to be carried out manually, and depending on the situation at the workplace, the vehicle itself had to be moved forward, backward, or rotated in order to use a forklift. It takes a lot of effort, and a lot of manpower and time are wasted.Therefore, for the contractor, there is a large expense for loading and unloading, and there is a large loss due to wasteful expenditure.In addition, the door is only in the rear. Therefore, a number of disadvantageous effects such as those described in (al) of the previous section were likely to occur, and there were often dangers (C1 Problems to be Solved by the Invention) As mentioned above, we have eliminated the disadvantageous condition that conventionally required loading and unloading only from one side of the door, and now we have installed hinges on the left and right side walls and three sides of the rear of the box-shaped cargo box. It is constructed so that it can be completely opened, and when loading and unloading, it can be loaded and unloaded freely from either the left or right rear, and the luggage can be manually moved from the rear of the inside of the box to the front, which is deep inside the box. This eliminates the hassle of loading and unloading palletized cargo using a heavy forklift truck, and makes it easy to directly load and unload cargo from three sides to the destination, eliminating the need for the vehicle to be rotated forward and backward depending on the on-site situation for loading and unloading. The inside of the box was difficult to clean5, and the ventilation was poor, which caused many dangers and harm.

(b) Structure of the invention (a) Means for solving each problem and operation of (b), the present invention is a method for carrying a cargo box (2) similar to the conventional one placed on a truck bed (0). Fix it with a fixing device, and attach four doors (31(
41 (51 (6)) are installed on both sides with the same shape, and when closed, the conventionally used bolts συθ邊α304 are inserted above and below, and a rubber panel 7 etc. is installed in the gap between the doors to seal the inside of the text box. The door of the Aη (Foundation) is opened and closed using a four-clasp hinge, and when it is closed, it is closed and sealed using the bar shown in c!1 (2). In the case of , when the width of the door becomes wider, add a to the center of the door.
When loading and unloading cargo into a cargo box configured in this way, a bolt bar is installed to strengthen the side walls like in the QOQ. Five doors are sequentially opened at the required locations to ensure that the loading and unloading process is not dirty.Also, when loading and unloading heavy items, a forklift is used from both sides to move the truck to the desired location. Since direct loading is possible, there is no need for manual labor to move cargo indoors, reducing manpower.
In addition, the interior of the interior should be neatly decorated to avoid damage to luggage due to the movement of the car, and there should be no protruding unevenness.If there is not enough luggage and a landing area is created inside the interior, a partition plate like the one shown in Figure 4 should be placed at the end of the luggage. A board (2) with a split part to be fitted is installed vertically inside the door on both the left and right sides of the room, and the ends of the partition plate (2) are inserted into the split parts on both the left and right sides to straddle the left and right sides of the room. This is to prevent the load from collapsing when the load sways back and forth, and if necessary, it is fitted in several places to prevent the load from collapsing. (2) shows the driver's cab.

(cl Example) Conventional box-type truck boxes have doors that are limited to one side at the rear, so cargo must be loaded with the rear door open and moved manually to the front of the box. Because of this, it took a lot of effort to load and unload cargo.The present invention has doors on both sides that can be opened, so there is no need to move the internal cargo back and forth, and loading and unloading can be done directly from the side. This makes loading and unloading easier, and especially in the case of heavy items, it can be loaded straight from the side to the loading area using a forklift, which eliminates all the disadvantages of conventional methods, such as requiring manual effort, effort, and time, and is economically advantageous. It can be used as a box-type truck.

e＼) Effects of the invention As stated in the previous paragraph (b) (LL) (b) and (el), the present invention overcomes the disadvantages of the conventional manual labor and time required in the packing box. In order to overcome these conditions, there are doors that can be fully opened on both the left and right sides and on all three sides, so you can load and unload by opening the doors at the necessary locations as needed, and the forklift can be used effectively from any location. It also eliminates the inconvenience of having to move or rotate a large vehicle back and forth in a small worksite due to the use of a forklift when loading and unloading, reducing manpower and cost. Being able to shorten the wholesale time not only reduces transportation costs, but also provides a vehicle that meets the optimum requirements for express delivery for both the carrier and the client, making it a truly advantageous and economical vehicle.

Claims (1)

[Claims] Conventionally, when transporting cargo, when loading and unloading onto a box-type truck, only one door was provided at the rear or on either the left or right side, and the cargo had to be loaded and unloaded from only this location. In order to eliminate such disadvantageous conventional conditions, the present invention fixes a cargo box placed on the cargo bed of a car to the cargo bed, and the exterior of the box is made of aluminum or aluminum. It is constructed using materials such as iron and stainless steel, and has doors that can be opened not only at the back of the box but also on both left and right sides, so that the door can be opened from any location necessary for loading and unloading cargo. This method can also be used for containers, such as box-type trucks with opening/closing doors on the rear and both sides.
