Description

  The present invention relates to a carriage that carries a work by placing a tool or the like while being pushed by a person on a track.

  Conventionally, a cart that is pushed by a person to move on a track has a width of about 1.2 to 1.6 m, a length of about 1.5 to 1.8 m, and a weight of about 50 kg. In order to transport the car to a certain location, it has to pass through a narrow space, and as a countermeasure, a cart with the cart body folded in two in the horizontal direction has been developed.

Although this cart was half the size of the cart body, the weight did not change and it was difficult to carry it by human power. Therefore, a cart shown in Patent Document 1 has been developed. This shows a carriage that can disassemble a carriage main body on which cargo is placed into two parts and separate the wheels into four parts as a whole for transportation.

  However, the cart shown in Patent Document 1 can be disassembled into two parts, but this is also large in shape. In order to transport this to a desired place by human power, It is difficult to pass through a narrow place, and in an elevated place like the Shinkansen, it is necessary to lift an inclined surface or a steep staircase. It was heavy and inconvenient.

  SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a cart that is more easily disassembled and easily assembled and disassembled for convenient transportation.

  In the cart according to the present invention, a rectangular structure is formed by two vertical frames and two horizontal frames, and the vertical frame and the horizontal frame are connectable or detachable, and a top plate is disposed inside the rectangular structure. The carriage main body has a mounting portion on which the top plate can be freely fitted, and a wheel support is fixed to the vertical frames of the carriage main body, and a bearing is mounted on the wheel support. The wheel is made detachable through the body (claim 1). With this configuration, the cart body is disassembled from the bar-shaped portion of the two vertical frames, the two horizontal frames, and the top plate, and is also divided into two sets of wheels. Further, the reinforcing rod constituting the carriage main body is also detachable from a rectangular structure of a horizontal frame and a vertical frame (claim 2). As a result, the reinforcing rod is also disassembled into a plurality of rod-shaped portions, which are finely disassembled.

  To assemble the carriage, the two horizontal frames and the vertical frame are connected to each other to form a rectangular structure, a reinforcing rod is attached, and then the top plate is provided on the inside of the rectangular structure from above. The main body of the carriage is assembled by fitting into the part, and the wheel is fitted into the wheel support fixed to the lower part of the vertical frame via the bearing body to complete. As described above, when the top plate is placed on the mounting portion, the vertical frame and the horizontal frame are not moved, and the connection is not released. Conversely, in order to disassemble the carriage, if the top plate is removed from the mounting portion of the rectangular structure, the connection between the vertical frame and the horizontal frame is released. Then, the vertical frame and the horizontal frame are removed, the reinforcing rod is removed, and the wheel is removed.

  The horizontal frame and the vertical frame are connected to each other by forming a pin on one side and forming a fitting groove on the other side to engage with the pin (Claim 3). Thereby, connection and removal of a vertical frame and a horizontal frame become easy. In addition, the wheel support body has guide portions arranged side by side, and the bearing body has two longitudinal grooves, and the longitudinal grooves of the bearing body can be fitted into the guide portions of the wheel support body. (Claim 4). Thereby, attachment to a cart body and removal from a cart body are easy with a fitting structure.

  As described above, according to the present invention, the cart can be disassembled finely. That is, it is divided into two vertical frames, two horizontal frames, a top plate, and two wheels. Of course, the reinforcing rod is also disassembled. For this reason, it becomes many parts and the weight of each becomes light, and the vertical frame, the horizontal frame, and the reinforcing rod are rod-shaped and are not stretched. Therefore, it is advantageous for conveyance.

  The vertical frame and the horizontal frame are easily connected and have an advantage that the combined state of the vertical frame and the horizontal frame is locked by placing the top plate on the mounting portion inside the rectangular structure. . By removing the top plate from the mounting portion of the rectangular structure, there is an advantage that the vertical frame and the horizontal frame constituting the top plate can be easily released.
