Abstract

PURPOSE:To improve loading and unloading efficiency by providing a swing gate capable of being opened and closed on a horizontal rotational axis and having a retractable sloping member for facilitating the cargo work. CONSTITUTION:A vertical swing gate 1 in a standing position, when released, is swung down about its base end to the outside on a hinge 9 with the gate end confronting the ground and then a sloping member 2 is slidably withdrawn from the gate 1 through an opening 13 into such length as to permit its end 21 to make contact with the ground, thereby forming a sloping member inclining to the ground. A cargo is forced up or slidably moved along this sloping member to make the loading and unloading of the cargo easy. At the end of this cargo work, the gate 1, after retracting the sloping member 2, is swung back in a standing position for closure. Therefore, the cargo work can be performed easily.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an on-vehicle box-like structure. That is, the present invention relates to Shelter 9 containers and other vehicle-mounted box-like structures that are mounted on the loading platform of a truck or the like and are transported with luggage loaded therein.

``Prior Art'' In such shells, the door has conventionally been opened and closed using a vertical pivot shaft.

In other words, there are various types of doors for shelters, etc., such as left-hand opening, right-hand opening, single-opening, and double-opening. It could be opened and closed horizontally to the left and right using vertical hinges installed on the side edges.

By opening and closing such doors, cargo, etc., was loaded and unloaded between the vehicle-mounted shelter and the ground.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out with such conventional shelters.

That is, when loading and unloading the above-mentioned cargo, etc., it was necessary to use a forklift or prepare a separate slope plate. It has been pointed out that especially when the weight of the cargo is heavy, it is necessary to use these devices to lift and lower the cargo between the floor of the car shelter, etc. and the ground, which is time-consuming and inefficient. was there.

This point was pointed out in the conventional example.

In view of these circumstances, the present invention has been made to solve the problems of the conventional example, and has a folding door that opens and closes with a horizontal rotation axis, so that luggage, etc. The purpose of this project is to propose an on-vehicle box-like structure that can be easily loaded and unloaded. In addition, by constructing the folding door with the auxiliary door base end and the door body, there is no difference in level from the floor, and by installing the specified adjustment jack, it is easier to pull out luggage horizontally. Another purpose is to propose an in-vehicle box-like structure that can be used and adjusted.

"Means for Solving the Problem" The technical means of the present invention to achieve this object are as follows.

This vehicle-mounted box-like structure is a box-like structure that is mounted on a vehicle and into which luggage and the like are loaded, and has a folding door and a slope member.

The base end of the folding door is pivotally attached to the floor by a horizontal rotation axis, and can be opened and closed outward and upward and downward, and is used for loading and unloading the above-mentioned cargo, etc.

The slope member is housed within the folding door and can be slid and pulled out from an opening provided at the tip of the folding door.

In addition, claim 2 is as follows. In other words, the folding door includes a door base end portion having one end pivotally attached to the floor, and a door body portion pivotally attached to the other end of the door base end portion.

Furthermore, claim 3 is as follows. That is, one adjustment jack is provided on the outer surface of the tilting door, and the adjusting jacks form a pair of left and right, the base end of which is pivotally attached to the tip of the tilting door, and when not in use, it can be tilted. It is attached to the door and when in use, the tip rotates and is grounded.

"Function" Since the present invention consists of such means, it works as follows.

This vehicle-mounted box-like structure is mounted on a loading platform or the like, and cargo and the like are loaded therein and transported. Then, cargo, etc., is loaded between this onboard box-like structure and the ground.

Unloading will be carried out as follows.

First, open the folding door, pivot outward from the base end, and fold it down so that the tip faces the ground. At the same time, the slope member housed in the folding door is slid from the opening and pulled out by an appropriate length, and its tip is grounded.

In this way, the tilting door and the slope member form a slope that slopes downward at an appropriate angle toward the ground. Therefore, even if the baggage is heavy, it can be easily loaded on the slope.

It will be unloaded. After loading and unloading the cargo, etc., the folding door that accommodates the slope member is rotated inward to stand up and close.

Regarding claim 2, it is as follows.

That is, as mentioned above, a slope is formed by the folding door and the like for loading and unloading cargo and the like. At this time, the auxiliary door base end is first tilted outward to, for example, a substantially horizontal position, so that it is substantially flush with the floor of the vehicle-mounted box-like structure. At the same time, the door main body and the like form a slope that slopes downward in a straight line toward the ground. In this way, there is no need to slope the edge of the floor, and there is no difference in level between the floor and the floor, so that cargo can be loaded and unloaded without any trouble.

Furthermore, claim 3 is as follows.

That is, the tilting door is opened and rotated outward around the base end to be folded down, and the adjustment jack is rotated around the base end to bring the tip of the adjustment jack into contact with the ground. By adjusting the length of the adjustment jack as appropriate, the adjustment jack serves as a leg to hold the door or the like in a horizontal position. Then, the luggage, such as measuring instruments, etc., loaded in the on-vehicle box-like structure are pulled out onto the horizontally-positioned folding door, and the use, adjustment, inspection, etc. thereof are performed.

After these adjustment jacks are attached to the tilting door, the tilting door is rotated inward to stand up and close.

In addition, this adjustment jack is used to support the downward tilting door between the ground and the floor when loading and unloading the above-mentioned cargo, etc.
It can also be used for reinforcement.

"Example" The present invention will be described in detail below based on the example shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

FIG. 2 is a perspective view showing the loading and unloading state of luggage, etc. in the same embodiment. FIG. 3 is a perspective view showing how the folding door is used in a horizontal position in the same embodiment. FIG. 4 is an explanatory side view of the same embodiment.

First, the structure and the like will be explained in the following order: the outline of the shelter S, the raising/lowering door 1, the slope member 2, and the adjustment jack 3.

The outline of Shelter S is as follows.

Shelter S is an example of an on-vehicle box-like structure, and is mounted on the loading platform T1 of a means of transportation such as a truck T, with nine measuring instruments, luggage, etc. loaded inside, and transported to the destination. be done. In other words, shelter S is on floor 4. Ceiling 5. It is provided with left and right walls 69, front and rear walls 7, etc., which are assembled and fixed to each frame frame 8, and form a box shape.

In Figure 1.2.3, T2 is the tire of truck T,
3 is a rear flap plate of the truck T, and T4 is a side flap plate of the truck T. Further, the on-vehicle box-like structure is not limited to the illustrated shelter S, but may be, for example, a container for loading luggage, or various other structures.

The outline of Shelter S is as follows.

Next, the folding door 1 will be described.

The folding door 1 is assembled to the rear wall 7. This tilting door 1 is pivoted to a frame frame 8 of the floor 4 by a hinge 9 whose lower base end is a horizontal rotation axis and which can be expanded outwardly.
It can be opened and closed outward and up and down (see Figure 4, etc.), and is used for loading and unloading cargo, etc. The folding/tilting door 1 also has an auxiliary door base end portion 1.one end of which is pivoted to the frame frame 8 of the floor 4 by a hinge 9 as described above. And this door base end I
It consists of a door main body part 1□, which is a main body pivotally connected to the other end of the door body by a hinge 10 that can be expanded outwardly (see FIG. 4, etc.).

As shown in FIG.
It opens and closes in a horizontal position, flush with the other hand. In the horizontal position, the edge of the door base end II contacts the frame frame 8 of the floor 4 to maintain that position. As shown in FIG. 4, the door body part 1□ is in an upright position on the door base end II, a horizontal position in which it is rotated 90 degrees outward together with the door base end 1j, and a horizontal position on the door base end 11. On the other hand, the hinge 10 rotates further outward from the horizontal position to open and close the position tilted downward in a straight line toward the ground. In this downwardly inclined posture, the tip of the slope member 2, which will be described later, comes into contact with the ground to maintain that posture.

In addition, when a trolley is often used for loading and unloading cargo, etc., rails are appropriately attached to the folding door 1, that is, the door body 1□, etc.

The folding door ■ looks like this.

Next, the slope member 2 will be described.

The slope member 2 is housed inside the folding door 1, and is provided with an opening 1 provided at the tip of the folding door 1. It can be pulled out by sliding it out. That is, the slope member 2 has a flat plate shape in the illustrated example, and corresponds to the door main body 1 when not in use.
□It is stored in a storage section (not shown) provided in
(See Figure 1.4, etc.) And when in use, its tip 2I
by pulling out the appropriate length from /) (2nd and 4th
(see figures, etc.), the downward inclination angle of the slope member 2 and the tilting door 1 is adjusted.

Incidentally, the slope member 2 may be formed, for example, as follows, other than the flat plate shape shown in the drawings. In other words, if a trolley is often used for loading and unloading cargo, etc., a flat plate with rails attached to it, or a horizontal frame with a 2° tip end fixed to a vertical frame serving as the left and right rail frames, is used. Instead, it is conceivable to use a frame formed as a substantially U-shaped frame.

The slope member 2 has this structure.

Next, the adjustment jack 3 will be described.

The adjustment jacks 3 are attached to the outer surface of the door main body part 12 of the tilting door 1, form a left and right pair, and have their base ends pivotally attached to the distal end of the door main body part 1□. When the adjustable jack 3 is not in use and the folding door 1 takes an upright position, it is attached to the door main body part 1□ by a mounting member (not shown). When it assumes a horizontal position, the tip rotates and touches the ground, and assumes a vertical position perpendicular to the folding door 1.

That is, the adjustment jacks 3 are provided in pairs on the left and right, and each includes an outer cylinder 31 whose base end is pivotally connected to the door body 1□ via a bracket with a pin, and this outer cylinder 3. It is provided with an inner cylinder 3□ which is fitted into the cylinder so as to be movable forward and backward. Inner cylinder 3
A grounding pad 11 is pivotally attached to the tip of □ by a pin, and an interlocking frame 12 is interposed between the left and right outer cylinders 3.

There are various types of adjustment jacks 3, similar to general jacks. That is, as methods for adjusting the overall length by moving the inner cylinder 3□ forward and backward by an appropriate amount with respect to the outer cylinder 3I, there are a screw type in which both are screwed together, a so-called taper type, and so on. In the illustrated example, the Taber method is used, and the inner cylinder 3□ is tightened from the side with an inclined plate (not shown) with screws 33, and the tightening is adjusted by releasing the state, etc. The inner cylinder 3□ is moved forward and backward relative to the outer cylinder 31 by an appropriate amount. Also, the illustrated adjustment jack 3
It consists of a two-stage type with a square outer cylinder 3I and an inner cylinder 3□, but round and three-stage types are also available as appropriate.

It may be a multi-stage type such as a four-stage type. In particular, when the adjustment jack 3 is also used to reinforce the tilting door 1 that is tilted downward during loading and unloading of cargo, etc., a multi-stage type is used to adapt it to various inclination angles.

Reference numeral 13 denotes a holding arm attached to the left and right adjustment jacks 3, respectively. This holding arm 13 is comprised of an arm 131 whose ends are pivotably connected with pins so as to be bendable.
, 132, the other end of one arm 13 is pivotally connected to the door body 1□, and the other end of the other arm 13□ is pivotally connected to the outer cylinder 31 of the adjustment jack 3.

When the holding arm 13 is not in use, that is, when the adjustment jack 3 is not used, it is bent and attached to the door body portion 1□ together with the adjustment jack 3. When in use, that is, when the adjustment jack 3 is used and is placed on the ground in a vertical position, it extends linearly and interposes between the door main body 12 of the raising/folding door 1 and the outer cylinder 38 of the adjustment jack 3, allowing adjustment. The jack 3 is locked and held in a vertical position.

Wordshu-bushi Jiyatsuki 3 is like this.

The above is the explanation of the configuration, etc.

The operation etc. will be explained below.

5 and 6 are schematic side views for explaining the operation of the embodiment. FIG. 5 corresponds to FIG. 2 and shows the state of loading and unloading cargo, etc., and FIG. 6 corresponds to FIG.
Shows how it is used in a horizontal position. The operation, etc. will be described below with reference to FIGS. 5 and 6.

The shelter S, which is an on-vehicle box-like structure, is mounted on a loading platform T of a truck T or the like, and is transported with measuring instruments and other cargo M loaded therein. Loading and unloading of cargo, etc. M between the shelter S and the ground is performed as follows.

First, the folding door 1 is opened and rotated outward by the hinge 9 around the base end and folded down, so that the tip thereof faces the ground. Along with this, the slope member 2 was housed inside the folding door 1.
from the opening 13 and pull it out by the appropriate length,
The tip 2. ground.

In this way, the raising/lowering door 1 and the slope member 2 form a slope that slopes downward toward the ground at an appropriate angle, as shown in FIG. 2.4.5. There, luggage etc.
Even if they are heavy, they can be easily loaded and unloaded by being pushed up and slid down along the slope.

After the loading and unloading of the cargo, etc. M is completed, the folding door 1 housing the slope member 2 is rotated inward to stand up and close as shown in FIG. 1.4.

Claim 2 is as follows.

In other words, as shown in Figure 2.4.5 above, luggage etc. M
For loading and unloading, a slope is formed by the tilting door 1, etc.

At that time, first the auxiliary door base end 1. However, hinge 9
For example, it is rotated outward to a horizontal position and is brought down, and its edge is brought into contact with the frame frame 8 of the floor 4 to maintain the horizontal position, so that it is flush with the floor 4 of the shelter S. At the same time, the door body portion 1□ and the like are further rotated outward by the hinge 10, forming a slope that slopes downward linearly toward the ground.

In this way, the frame frame 8 at the edge of the floor 4 does not need to be sloped, and no step is created between it and the frame 4. In other words, the auxiliary door base end 1 of the folding door 1 is
1 and the door body 12 are integrally formed instead of being formed separately, unless the frame frame 8 at the edge of the floor 4 is tilted, the folding door 1 will not be able to take a downwardly inclined position below the horizontal position. It disappears. Furthermore, the base end of the folding door 1 and the frame frame 8 of the floor 4
There will be a difference in level between the two.

However, by forming the folding door 1 in parts as described above, the folding door 1 can be tilted downward without the need for tilting the frame 8 of the floor 4, and no difference in level occurs. As a result, the loading and unloading of luggage etc. M can be carried out without any hindrance.

Claim 3 is as follows.

That is, the tilting door 1 is opened and rotated outward around the base end to be brought down, and the adjusting jack 3 is rotated around the base end to take a vertical position and the grounding pad 11 at the tip thereof is brought into contact with the ground. The length of the adjustment jack 3 is adjusted as appropriate in accordance with the unevenness, slope, etc. of the ground, so that the adjustment jack 3 can be used as a third leg.
4. Hold the folding door 1 in a horizontal position as shown in Figure 6.

Note that the vertical position of the adjustment jack 3 is
Reliably held by elongation. Further, the slope member 2 housed in the folding door 1 is pulled out horizontally by an appropriate length as necessary and used as an extended horizontal surface.

Then, the baggage M loaded in the shelter S, such as measuring instruments, etc., is pulled out onto the vertical door 1 in a horizontal position, and its use, adjustment, inspection, etc. are performed. After these are completed, the adjustment jack 3 and the holding arm 13 are attached to the raising door 1, and the raising door 1 is rotated inward to stand up and close as shown in FIG. 1.4.

The adjustment jack 3 can also be used for reinforcement by supporting the downwardly inclined raising and folding door 1 between the ground and the ground during loading and unloading of the above-mentioned baggage M, etc. That is,
By setting the multi-stage adjustment jack 3 in a vertical position and adjusting its length to be short as appropriate, the tilting door 1 and the slope member 2, which slope downward to form a slope as shown in Fig. 2.4.5, can be supported. It is also used for reinforcement purposes.

The above is the explanation of the operation, etc.

"Effects of the Invention" As explained above, the in-vehicle box-like structure according to the present invention has the following features:
By forming a slope with a tilting door that opens and closes with a horizontal rotation axis, it becomes easy to load and unload heavy items. That is, loading and unloading can be easily performed without using a forklift or preparing a separate slope plate, and cargo handling efficiency is significantly improved.

In addition, in the vehicle box-like structure of claim 2,
By constructing the folding door with a predetermined auxiliary door base end and the door main body, there is no need to slope the edge of the floor and there is no difference in level between the floor and the floor. In other words, the troublesome work of sloping the edges of the floor is eliminated, and a decline in its strength is prevented.In addition, a downwardly sloping slope can be formed without creating a step with the floor, and cargo can be loaded and unloaded without any hindrance. be exposed.

Furthermore, in the vehicle-mounted box-like structure of claim 3, in addition to the above, by providing a predetermined adjustment jack, it is possible to pull out luggage such as measuring instruments onto the folding door held in a horizontal position. , its use and adjustment.

It is efficient to carry out inspections, etc. The adjustment jack can also be used to reinforce the folding door when loading and unloading heavy loads, thereby preventing damage to the folding door and the slope member.

In this way, the problems that existed in this type of conventional example are completely eliminated, and the effects of the present invention are remarkable and great.
