Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a method for lifting and lowering cargo vehicles to make it safe and easy to climb onto and off the loading platform. Regarding equipment.

0002

[Conventional technology]

Regarding the elevating device to the loading platform of a freight vehicle, the prior art was published in the public gazette (1983-1983). The survey was conducted based on the following: (1964). As a result, a medium- and large-sized cargo vehicle for the same purpose as the present invention was Lifting devices suitable for moving vehicles are disclosed in Utility Application No. 58-45744 and Utility Application No. 15032-1983. There are two cases of 9. The device of Utility Application No. 58-45744 uses a folding step as a loading platform. Because it is stored under the floor of the car, it is only effective when the rear door opens on both sides, and it is not suitable for normal cargo vehicles. It cannot be installed on moving vehicles. On the other hand, the device of Utility Application No. 62-150329 has multiple remote controllers. The structure is complicated because the rear gate is suspended by a link as a step for raising and lowering. There are difficulties in terms of installation and cost.

0003

[Problem that the idea aims to solve]

Regarding lifting equipment to the loading platform of medium-sized and large-sized trucks, the loading platform has a ground clearance of approximately 1,000 yen. 000mm to 1,500mm, multiple steps are required. This point Therefore, the above-mentioned prior art has a complicated structure for setting and storing. that Therefore, the weight of the vehicle body increases, which affects the cargo load and fuel efficiency. Also, special It is difficult to install at general maintenance shops because it has many components and requires modification of the vehicle body. be. Furthermore, since the installation process is numerous and time-consuming, it reduces the operating rate of freight vehicles. There are also problems such as This invention is a loading/unloading device that has a simple structure and is easy to install. It provides:

[Means to solve the problem]

Fix the mounting board (2) to the appropriate place inside the gate (1), and attach the top surface of the mounting board (2). Connect part of the tip of the support frame (5) of the step device (4) with the universal joint (3) installed in the Attach the locking tool (6) to the gate (1) at the appropriate position where the support frame (5) will come into contact with the gate (1) during storage. Install it inside the. Furthermore, there is a hole (8) for height adjustment of the step (7) in the support frame (5). and a post holding plate (9) at the lower end of the post frame (5). This is a lifting device for loading and unloading a freight vehicle, which has the above-described configuration.

[0005]

[Effect]

As a result of the above-mentioned configuration, the present invention has the following advantages: for example, as shown in FIG. When you want to go, first open the gate (1), lower it to the bottom of the platform, and then open the gate (1). 1) The step device (4), suspended horizontally with the locking device (6), is in front of you. Located in Next, remove the step device (4) from the locking tool (6) by hand and move it freely. Using the fitting (3) as a base, pull it toward you and lean it diagonally to the rear of the cargo platform. do. At this time, the lower end of the support frame (5) of the step device (4) is on the road surface, and the upper end is free. The safety of the step device (4) is improved because it is supported by the gate (1) by the joint (3). The quality is high. In addition, as shown in Figure 2, a column holding plate (9) is attached to the lower end of the column frame (5). If the step device (4) is rotatably mounted, the grounding performance of the step device (4) is improved. Furthermore, the illustrated Make a height adjustment hole (8) on the side of the support frame (5) and secure the step (7). The height of each step (7) can also be changed by removing and attaching bolts or screws. can. After completing the lift to the loading platform, lift the step device (4) in the reverse order of the above procedure. , turn the universal joint (3) horizontally as a reference point, and fit the support frame (5) into the locking tool (6). and store it suspended inside the gate (1).

[0006]

【Example】

Examples of the present invention will be described below. The first figure is a perspective view. Medium/large cargo automatic Attach the mounting board (2) to the appropriate place inside the gate (1) installed at the rear of the car using bolts or screws. the end of the support frame (5) using the universal joint (3) provided on the top surface of the mounting board (2). This is a multi-stage lifting device with connected ends. The universal joint (3) should be used when storing the device. The step device (4) rotates approximately 90 degrees left and right, and a slight angle forward and backward. If it is a structure, there are no restrictions on the component parts. For example, metal fittings with directional rotation axes, chains, and even reinforced hoses can be used. Gender bodies can also be used. The locking tool (6) is made of a U-shaped leaf spring and is attached to the inside of the gate (1) with bolts or screws. When the step device (4) is hung and stored horizontally, the support frame (5) is fitted. It is something that you enter and hold. Figure 2 shows the height of the step (7) being adjustable. This is intended to improve the grounding performance of the step device (4), and is installed on the side of the support frame (5). Drill multiple height adjustment holes (8) at appropriate locations and attach the steps (7) with bolts or screws. It is something that sticks. When changing the height of step (7), first After removing the bolts or screws of step (7), set each step (7) to the desired height. Set it in the adjustment hole (8) and secure it to the support frame (5) again with bolts or screws. . The column holding board (9) is attached to the lower end of the column frame (5) with bolts, etc., and the step installation is carried out. An elastic body is provided to improve the grounding performance of the seat (4).

[Effect of the idea]

It is possible to climb onto the loading platform of a truck equipped with this invention with effortless movement and posture. There is no need to jump from the platform to the ground when getting off the truck, so there is no risk of sprains or fractures. Accidents are also reduced. Furthermore, the present invention has the following effects. (1) The method of using the proposed lifting device is extremely simple, and it is installed diagonally to the loading platform. This makes it easier to go up and down, reducing both physical and mental fatigue. (2) Easy lifting and lowering operations allow you to lift and lower while holding the load in your hand, making it easy to handle small items. Helps speed up work. (3) The proposed step device has a structure in which the lower end of the support frame is directly in contact with the ground. The load on gates and mounting hinges is small, the durability of the gate is not compromised, and the vehicle is in use. It can also be retrofitted. (4) The step device is suspended and stored inside the gate, but it does not affect the cargo platform volume or loading capacity. The impact is extremely small. (5) This invention has a simple structure, so there are fewer failures and fewer parts, so it is easy to install. is completed in a short time. In addition, according to the present invention, conventional stepladders can also be used, so the cost is low. It becomes possible to commercialize the product at low cost.
