[Industrial applications]

 The present invention relates to an improvement of a simple connector used for connecting, for example, a motor car (railway car) and a bogie (iron toro) or connecting bogies to each other.

[0002]

[Prior art]

 As shown in FIG. 8, the conventional simple connector used for connecting the motor car and the bogie or connecting the bogies has a pin hole Sb at the tip Sa of the connecting rod S attached to the motor car (not shown) or the like. On the other hand, pin holes Ra, Rb are also formed on the upper and lower sides of the connecting tool R having a substantially U-shaped cross section attached to the truck T, and these pin holes Ra, Sb, Rb are coaxially positioned. After they are aligned, the connecting pin P is inserted from above to be connected. In the figure, Y is a stopper shaft that contacts the head Pa of the connecting pin P to prevent it from coming off, and Ya is a weight attached to the lower end of the rotary lever of the stopper shaft Y.

[Problems to be solved by the device]

 The simple coupler configured as described above has the advantage that the overall structure is simple and can be manufactured at a relatively low cost, but on the other hand, if the coupling operation is extremely difficult, or if a finger is caught during the coupling work, an injury may occur. There was a drawback that many of the accidents mentioned occurred.

That is, in the case of connecting vehicles using a conventional simple connector, a worker holds the connecting rod S shown in FIG. 8 in hand and asks the driver of the motor car to “30 cm ... 20 cm ... 10 cm”. When the tip Sa of the connecting rod S is inserted into the connecting tool R and the pin holes Ra, Sb, Rb are located on the coaxial line, the connecting pin P is inserted from above to connect the two. However, it is very difficult to finely operate the motor car to match the pin holes Ra, Sb, Rb, and it is not possible to align the pin holes Ra, Sb, Rb, and these match. It was also difficult to insert the connecting pin P into the pin holes Ra, Sb, Rb, and it took time to perform the connecting work, or it was said that a finger or the like was caught between the connecting rod S and the connecting tool R at the time of connecting, resulting in an injury. There was a problem that an accident occurred.

Therefore, the technical problem of the present invention is that the pin holes provided in both the connecting rod and the connecting tool are easily aligned on the coaxial line, and the connecting work by inserting the connecting pin is extremely easy, and To be safe.

[0006]

[Means for Solving the Problems]

 Means taken in the present invention to solve the above technical problems are as follows. Insert the connecting rod attached to one vehicle into the connecting tool with a U-shaped cross section attached to the other vehicle, and insert the connecting pin into the pin holes formed in the connecting rod and the connecting tool. In the coupler configured to connect both vehicles by

(1) The dowel having the pin hole penetratingly provided on the bottom surface of the connecting rod is projected, and the pin hole is communicated with the inner bottom surface of the lower plate constituting the connecting tool. In addition, a dowel hole configured so that the dowel can be fitted thereinto, and a guide portion for guiding the connecting rod that is inserted to fit the dowel into the dowel hole are provided.

(2) The guide portion is composed of a slope surface that contacts the bottom surface of the dowel and guides the connecting rod into the inside of the connector, and a guide groove that guides the dowel and guides the dowel into the dowel hole. .

[0009]

[Action]

 The above means operate as follows. According to the means described in the above (1), when the dowel of the connecting rod is fitted into the dowel hole by being guided by the guide portion of the connecting device, the upper and lower pin holes of the connecting device and the pin holes of the connecting rod are automatically formed. Since it is aligned on the coaxial line, the work of aligning the pin holes is very simple, and the connecting work by inserting the connecting pin can be completed safely and in a short time.

According to the means described in (2) above, when the tip of the connecting rod comes close to the inlet of the connecting tool, the connecting rod is released from the connecting rod so that the connecting rod will have a slope and a guide groove. It is possible to fit the dowels into the dowel holes naturally so that each pin hole can be positioned on the coaxial line.Therefore, it is necessary to manually operate the connecting rod to align the pin holes. As a result, it is possible to prevent an accident in which a finger or the like is caught between the connecting rod and the connecting tool and injured, so that the connecting work can be safely carried out. As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.
