Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foldable tool carrier for a two-tiered loading platform.

[0002]

[Prior art]

 Conventionally, a carrier with an edged loading platform cannot be folded, has a limited storage space, and has a problem of being carried by an automobile or the like.

[0003]

[Problems to be solved by the device]

 Conventionally, a carrier with an edged loading platform is not foldable and has a limited storage space, and it is inconvenient to take a place when carrying the carrier by car when it is needed.

According to the present invention, it is lightweight and does not occupy a storage space, it is easy to operate, and it can be stored with a slight gap after use, or can be hung on a wall or the like.

[0005]

[Means for solving the problem]

 The body is made of a lightweight aluminum alloy for easy carrying, and when folded it is as easy as possible and safe, and when folded it has the minimum dimensions. It is a lightweight, solid, and easy-to-store carrier.

[0006] In order to be able to enter the lower loading platform into the upper loading platform when folding, the upper loading platform is made slightly wider than the lower loading platform, and the upper frame of the upper loading platform is in the groove provided in the lower loading platform. By making it enter, the lower platform can be stored in the upper platform together with each mechanism.

Inevitably, the upper and lower pallets can be raised and lowered, so that the steps of folding and assembling the main body are performed, and by lowering the pallet to a predetermined position during assembly, each wheel can be It is designed to be able to run.

[0008] And the loading platform actuates the handle backwards by the operation of the slider attached to the support rod, passes through the track portion, and enters the fixing device provided at the rear end of the truck, and at the same time, , A rear frame is formed, and the weight of the loading platform can be used to lock the upper loading platform. Also, even during the folding process, the loading platform is supported by hand and the handle is returned to its original position. It can be removed by things.

[0009] In addition to the above, by storing the upper and lower loading platforms, the locks provided at both ends of the connecting rod and the front side of the lower loading platform automatically prevent the loading platforms from separating from each other, and It is designed so that the main body can be safely carried.

Furthermore, when storing the foldable body, there is an inconvenience that it has to be leaned up somewhere as it is. Therefore, the foldable stand provided on the rear legs is used for inverted storage. This stand also functions as a braking device for the rear wheels.

Further, when the main body is folded and the assembly process is performed again, by pulling the levers provided on the lower loading platform, the lock devices provided on the lower loading platform are disengaged, respectively. We are making an assembly process. Therefore, this mechanism is solved by the fact that each mechanism can operate the main body reliably and safely, and can be stored and carried in a narrow space.

[0012]

[Action]

 Normally, the main body is used to carry parts and tools, and when it is not needed, it can be folded and placed in a corner, hung on a wall, or because it is lightweight, it can be carried by hand.

In order to simplify the assembling and folding processes of the upper and lower loads as much as possible, the upper loads are immediately locked through the slides, and at the same time, the movable rear frame is provided. Moreover, since it is a slide type, the handle can be moved smoothly by the average force on both ends of the slide. The pallet is automatically folded and assembled by lifting and lowering the loading platform, which causes the connecting rods that operate at the same time to contract and spread the legs, so it is extremely simple and can be operated immediately by hand. You can do it. Moreover, the several lock devices built into the main body allow the main body to be safely moved or folded, and the folded main body can be stored in any condition. It

【Example】

 Examples will be described with reference to the drawings. The body (1), bottom (2), rear legs (17), front legs (20), etc. of the main body are made of lightweight and durable aluminum so that they are convenient to carry and each bushing has a bushing. Is built in to create a more robust and durable structure. Also, the assembly structure (39) of the main body has the lower loading platform (2) projecting forward of the upper loading platform (1) so that the feet do not get in the way during use. If there is an obstacle on the front wheel (18), it is designed so that one can step on the step (47) of the main body (39) with one foot and lift the front part of the main body to remove the obstacle and run. It is what The upper cargo bed (1) is made slightly larger than the lower cargo bed (2) in order to allow the upper and lower cargo beds (1) and (2) to be folded over each other so that they can be folded. The rear frame (49) is placed in the groove (48) of the lower platform (2), and the locking devices (13, 14, 24, 25, 34) of each part are provided on it so that it can be stored safely. , And is designed to be portable.

Regarding the durability of the rear leg (17), when a load is loaded on the upper bed (1) of the carrier, a heavier load is applied than that of the front leg (20). 35) The reinforcing process with (35a) makes it stronger, and when the main body is folded after transportation and use, the front leg (20) is placed between its edges (35) and (35a). Provided to prevent the possibility that the main lock (25) part will disengage from the locking part (45) of the connecting rod (16) due to vibration or the like when entering and folding the main body of the carrier and suddenly lowering the lower loading platform (2). It is true. In addition, since the connecting rod (16) described here acts only by pulling and does not apply a load, it is possible to use a material such as aluminum or synthetic resin, but the side surface of the connecting rod (16) Since the main lock (25) hits against and is locked, it is desirable that the thickness is 8 mm or more so that there is no distortion.

In order to make the load carrier (1) foldable, the truck (23) is attached to the side surface (51) downward from the front to the rear, and the slaigue (33) is placed in the pocket lock device (24). The locking of is further enhanced. The slider (33) is best made of nylon, which is smoothly operated and has excellent durability.

As for wheels, a swivel type wheel (18) provided on the front leg (20) is used, and a wheel (15) provided on the rear leg (17) is a large plastic. It is made of rubber and rubber, provided that it is lightweight and durable, and that the wheels of each other are mounted so that they do not interfere with any part of the body when the body is folded.

Regarding the foldable stand (11) attached to the rear leg (17), it is indispensable that the material is a material such as an iron material that can sufficiently support the bed. When the main body is folded (38), the folding stand (11) can be used to store the main body upside down as shown in the figure, and the stand bracket (37) can be used as a braking action when using the assembly (39). The rear wheel (15) is forcibly restrained by the deformed plastic spring (10) and the shaft (44) incorporated therein. To fold the body, the rear wheel (15) and the foldable stand (11) can be used to easily fold the body.

The assembly order of the main body will be described. First, while tilting the upper part of the folding main body (38) slightly forward, by pulling the lock release lever (32) and the lower loading platform auxiliary lock (14) at the same time, the lower loading platform (2) can be easily removed. While lowering the detached lower loading platform (2), place the lower loading platform locking device (13) on the frame shaft (9), and push the device to automatically operate by the spring provided therein. It is fixed. Next, while supporting the hanger (22) provided at the tip (50) with one hand, the handle (5) is moved with the other hand. As a result, the support bar (8) is lifted and moved about the support shaft (27) by the support shaft (46) and the slider (33), and when the support bar (8) is completely moved, the end of the truck (23) is moved. The movable rear frame (4) fixed to the bracket (3) which is moved at the same time as the slider (33) is locked to the part of the pocket lock device (24) incorporated in the part, is the rear frame of the upper loading platform ( It is installed before 49). In this state, the slider (33) does not separate from the pocket lock device (24) even if the main body is operated. Furthermore, the slider (33) that has entered the pocket lock device (24) can be completely locked by the upper loading platform auxiliary lock device (34), so that the slider (33) will remain stable after any impact. Wheels (15) and front wheels (18) allow traveling and transportation.

When the main body is returned to the folding process, first, while supporting the hanger (22), pull the handle (5) and the receiving plate (7) fixed to the rear frame (49) of the load carrier. As a result, the loading platform (1) is lifted and the support rod (8) is moved forward by sliding the handle (5) forward with the slider (33) released from the pocket lock device (24). The loading platform (1) is lowered by 90 °. The spring-operated lower platform lock device (13) attached to the rear section (41) of the lower platform is moved to the movable rear frame (4) which has already been moved so that the lower platform (2) is inserted therein. By lifting up by hand and approaching, the connecting rod (16) contracts the rear leg (17) and the front leg (20) around the connecting rod shaft (36), and at the same time, is incorporated in the lower platform lock device (13). The loading platform auxiliary locking device (14) is locked in the slot (6). Therefore, the main lock (25) attached to the side surface (52) of the tip portion of the lower loading platform (2) does not drop the rear part (41) of the lower loading platform (2) and the locking portion of the connecting rod (16). At (45), the legs (17) and (20) are further contracted to be locked one after another. For that purpose, the spacers (19) and (21) are attached to the upper cargo bed (1) and the lower cargo bed (2) so that the lower cargo bed (2) is linearly lowered in the upper cargo bed (1) and the cargo beds do not hit each other. Built into. Later, the main body (38) is stored on the floor by the folding stand (11) or hung on the wall using the handle (5).

[0021]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

In claim 1, since the single operation of the handle and all the mechanisms connected to the handle work together at the same time to fold and assemble, the process is extremely easy for anyone, even in an emergency. You can operate the main body with any kind of handling, and you can also operate the transport vehicle with a more reliable locking device with the upper bed auxiliary lock.

According to claim 2, by locking the lower loading platform locking device to the rear legs, the lower loading platform does not come off during transportation, and the assembly structure of the main body is strengthened so that items can be transported more safely. It is possible to drive.

[0024] In claim 3, a lock device having a pocket at the end of the truck is used to simplify the assembled and locked state of the load carrier, and when the lock is released, the load carrier is simply lifted. Therefore, the simple operation, the low cost of the structure, and the certainty of locking were achieved.

[0025] In claim 4, when the respective loading beds are folded by providing the main lock, instead of bothering to hang the hooks and the like to fix the loading beds together, they are locked by the automatic lock. When the lock is released, it can be done by simply pulling the lever, etc., eliminating the troublesome operation.

According to claim 5, when the main body is folded, the front wheels are compacted by being inserted into the rear wheel axle and the frame shaft, and when the main body is stored, the wheels do not stick out, which is an obstacle. It doesn't happen. Also, since the rear wheel is attached to the outside of the main body, it is possible to easily carry the folded main body by pulling it using the rear wheel instead of lifting it by hand.

[0027] In claim 6, the rear wheel forcibly restrained by the operation of the deformable plastic spring attached to the foldable stand is used to fold it when it is not needed, and it is pulled out when necessary. The stand can be used to store it upright, so you can put it anywhere you like, and when folding it, you can use this stand to secure it to the ground without wobbling and keeping it solid. The folding lock can be done easily in this state. Also, when an object is placed on the bed of the main body and is used as a transport vehicle, the stand can be used to act as a braking device.

[0028] In claim 7, the upper and lower loading platforms are made to fold each other by using the shafts provided in the front legs, rather than the form in which the loading platforms are put together in a state like a lid and integrated together. The type is less complicated in terms of manufacturing and handling, and the spacers hold the gaps between the loading platforms, making it easy to fold and insert the loading platforms. In addition, since the lower loading platform projects forward from the upper loading platform due to the folded structure of the loading platform in the state where the main body is assembled, there is no intention of operating the main body with the handle while paying attention to the feet.
