Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector covering suitable for a connector projecting from a front end and a rear end of a railway vehicle.

[0002]

2. Description of the Related Art Train couplers, which are well known as railway vehicles,
A flange having a flat portion that is in close contact with each other at the time of connection, a guide protrusion fitted to the center portion of the flat portion and a receiving concave portion, and an end of an air pipe for brake operation is opened in the flat portion; The air pipe is connected at the same time as the connection. If the coupler runs in a state of being exposed at the tip of the leading train, rain, snow, insects, dust, and the like jump from the opening of the air pipe and cause a failure of the brake device. As a means to do this, a cover made of iron or a cover made of nylon fabric has been used as a cover of the coupler.

[0003]

[Problems to be Solved by the Invention] However, since the iron cover is heavy (about 10 to 15 kg), not only is it difficult to mount and dismount the coupler, but also a plurality of workers are required to perform the mounting and dismounting work. It takes a lot of time, and the practical value is extremely low in view of the fact that it is frequently attached and detached.In addition, the connecting means to the coupler must be sturdy and large, and it is stored when not in use. And transportation was extremely inconvenient. Nylon fabric covers are lightweight and easy to put on and take off, but they have poor shape retention, and are not easily attached and detached due to the uneven shape of the coupler during cold snowfall or wind and rain. There was a drawback that it was easily damaged by the impact of sand and gravel scattered in the snow and water smoke that rolled up during traveling.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks of the prior art, the present invention provides a light-weight mounting frame fitted to an outer edge of a flange of a coupler, which is provided with a plurality of latches which are engaged with and disengaged from the coupler. A window hole through which the guide projection of the container is inserted is provided, and an opening of the bag body made of a flexible impact-resistant cushion sheet that fits into the guide projection is tightly fixed to the periphery of the window hole of the lightweight mounting frame. In addition, it is lightweight, easy to attach and detach to and from the coupler, and has excellent shape retention and durability.

[0005]

According to the present invention, since the bag of the flexible cushion sheet is fixedly mounted on the lightweight mounting frame, the bag can be carried alone, and the guide projection of the coupler is fitted in the bag. Insert and latch the latch to the outer edge of the tight flange of the coupler to prevent it from falling off and cover it.The end opening of the brake air pipe exposed on the flange surface, and the guide protrusion and receiving recess are all covered. In addition, foreign matter is prevented from entering.

[0006]

FIG. 1 is a schematic perspective view of a main part of a contact type coupler 1, in which a plurality of end openings 3 of an air pipe for a brake are exposed at a plane portion of a flange 2 which is in close contact with the coupling. A guide projection 4 and a receiving recess 5 at the time of connection are formed in the central portion. 2 to 4 are a plan view, a front view, and a side view of the covering device 10 according to the present invention fitted on the coupler 1 of FIG. 1, wherein the covering device 10 is a square made of a lightweight plate such as an aluminum plate. And a bag 21 made of a flexible impact-resistant cushion waterproof sheet that inserts and covers the guide projection 4 of the coupler. The mounting frame 11 is provided around each of the square flange surfaces 12. An up-down flange 13 fitted to the close-fitting flange 2 of the coupler is provided, and one side of the flanges 13 on both sides is engaged and disengaged to hold the close-fitting flange 2 of the coupler from the side. A possible raising / lowering latch 14 and a latch 15 which engages from above with a protruding portion such as a lock handle provided on the side of the coupler are attached to the flanges on the other side. In the center part, a window hole 16 for attaching the periphery of the opening of the bag body 21 is provided. In addition, a pair of latches 17, 17 for holding and locking the upper side of the contact flange 2 of the coupler are provided at both upper sides of the flange surface 12. A buffer plate 18 is attached.

The type of the latch is not limited to the above-mentioned embodiment, and the type and the mounting position of the latch can be appropriately selected so that the coupler 1 and the covering device 10 can be securely mounted and easily removed. It is. The bag body 21 has an elegant shape to allow the guide projecting portion 4 of the coupler to be loosely inserted therein, and is made of a sheet in which a cushion material is sandwiched between flexible shock-resistant and waterproof sheet material jackets. Is tightly fixed around the window hole 16 of the mounting frame. And
The bag body 21 can be compressed and reduced by an external force in the direction of arrow A.

[0008]

[Effect of the Invention] The present invention has a light overall weight (1.0 to 1.0).
(1.5 kg), not only is it easy to transport and unload the connector, but also the load of the latch that engages and disengages the coupler is small, so the structure of the latch is extremely simple and lightweight. It is easy to engage and disengage, and the bag body is an impact-resistant sheet with cushion material sandwiched between it, so it has excellent shape retention and is less likely to be damaged by the impact of sand and gravel that soars while traveling. It is waterproof and resistant to wind, snow, smoke and snow, and has excellent durability. Furthermore, since it is a flexible sheet, it can be compacted by external force when stored and can be stored in a narrow space such as a driver's seat. Therefore, even if the frequency of loading and unloading is high, the loading and unloading work can be easily performed, and since it has an elegant appearance, even if it is attached to the tip of the leading train, the elegant shape of the entire vehicle can be completely damaged. In particular, due to the flexibility of the bag, the opening of the bag is The perimeter of the window frame is fixed in close contact with the periphery of the window hole, thereby preventing invasion of foreign matter, and the upright flange of the mounting frame is fitted around the coupler, and the latch is held by engaging the coupler. Since it is securely attached to the connector, the practical effect is remarkable. For example, there is no possibility that foreign matter enters the air pipe end opening of the coupler without falling off during use.
