An opening portion of a bag body of a flexible shock-proof cushion waterproof sheet is closely attached and fixed to a peripheral edge portion of a hole, and a guide protrusion of a connector is loosely inserted in the bag body.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector cover suitable for a connector protruding from the front end and the rear end of a railway vehicle.

[0002]

[Prior Art]

 BACKGROUND ART A train connector known as a railway vehicle has a flange having flat portions that are in close contact with each other when they are connected, a guide protrusion and a receiving recess that are fitted to each other in a central portion of the flat portion, and the flat portion is provided. An end portion of an air pipe for brake operation is opened at this, and the air pipe is connected at the same time as the connection. When the coupler travels in an exposed state at the end of the leading train, rain, snow, insects, dust, etc. may fly in from the opening of the air pipe, causing damage to the brake device. An iron cover or a nylon cloth cover has been used as a covering device for the coupler as a means for closing the cover.

[0003]

[Problems to be solved by the device]

 However, since the iron cover is heavy (about 10 to 15 kg), not only is it difficult to attach and detach it with the coupler, but it also takes a lot of time with multiple workers for the attachment and detachment work. Considering the high frequency of disconnection, its practical value is extremely low, and the attachment means to the coupler must be sturdy and large, which makes it extremely inconvenient to store and transport when not in use. It was In addition, the nylon cloth cover is lightweight and convenient to put on and take off, but it is inferior in shape retention, and it is not easy to put on and take off due to the uneven shape of the coupler during cold snowfall or wind and rain. It had the drawback that it was easily damaged by the collision of the gravel that was mixed with the snow smoke and water smoke that winded up when the first train was running and scattered.

[0004]

[Means for Solving the Problems]

 SUMMARY OF THE INVENTION In order to solve the above-mentioned drawbacks of the prior art, the present invention provides a plurality of latches for engaging and disengaging the connector with a lightweight mounting frame fitted to the outer edge of the flange of the connector, and the guide protrusion of the connector is inserted therethrough. A window hole is provided, and the opening of the bag body made of a flexible shock-resistant cushion sheet that fits over the guide protrusion is tightly fixed to the peripheral edge portion of the window hole of the lightweight mounting frame. It is easy to put on and take off, and has excellent shape retention and durability.

[0005]

[Action]

 Since the present invention has a flexible cushion sheet bag fixed to a lightweight mounting frame, it can be carried by one person, and the guide protrusion of the connector is fitted into the bag body. The latch to the outer edge of the close-fitting flange of the coupler to prevent it from falling off, and then install the end of the brake air piping exposed on the flange, the guide protrusion, and the receiving recess. , Which prevents the entry of foreign matter.

[0006]

【Example】

 FIG. 1 is a schematic perspective view of a main part of a close contact type connector 1. A plurality of end openings 3 of a brake air pipe are exposed in a flat part of a flange 2 which are in close contact with each other at the time of connection, and a central part thereof is exposed. The guide protrusion 4 and the receiving recess 5 at the time of connection are formed. 2 to 4 are a plan view, a front view and a side view of a cover 10 according to the present invention, which is fitted to the connector 1 of FIG. 1, and the cover 10 is a square made of a lightweight plate such as an aluminum plate. A mounting frame body 11 and a bag body 21 made of a flexible shock-resistant cushion waterproof sheet for inserting and covering the guide protrusion 4 of the coupler. The mounting frame body 11 has a rectangular flange surface 12 respectively. Has a standing flange portion 13 fitted around the close contact flange 2 of the coupler, and holds the close contact flange 2 of the coupler from the side on the flange portion on one side of the flange portions 13 on both sides. And a latch 15 that engages from above with a protruding portion such as a lock handle provided on the side portion of the connector, and the collar 14 on the other side. A window hole 16 for attaching the peripheral edge of the opening of the bag body 21 is provided at the central portion of the flange surface 12. In addition, a pair of latches 17 and 17 for holding and locking on the upper side of the tight flange 2 of the coupler are provided on both sides of the upper portion of the flange surface 12, and further, in a suitable place of the flange surface 12, such as a felt-like flexible member. A buffer plate 18 is attached.

The latch is not limited to the above-mentioned embodiment, and the type and mounting position of the latch can be appropriately selected so that the connector 1 and the cover 10 can be firmly attached and can be easily removed. Is. The bag body 21 has an aesthetically pleasing shape in which the guide protrusion 4 of the connector can be loosely inserted, and is made of a flexible impact resistant, waterproof sheet material with a cushioning material sandwiched between the cushion body and the bag body 21. The peripheral edge of the opening is firmly attached to the periphery of the window hole 16 of the mounting frame. The bag body 21 can be compressed and contracted by an external force from the direction of arrow a.

[0008]

[Effect of the device]

 Since the overall weight of the present invention is light (about 1.0 to 1.5 kg), it is not only easy to carry and attach / detach to / from the coupler, but also a latch for engaging / disengaging the coupler is provided. Since the carrying load is small, the structure of the latch is extremely simple and lightweight, and it is easy to engage and disengage. In addition, the bag is an impact-resistant sheet with cushioning material, so it has excellent shape retention. Also, it is not easily damaged by collision of gravel flying up while driving, has waterproofness against wind and snow, water smoke, and snow smoke, and has excellent durability. Since it can be compacted by external force and stored in a narrow space such as the driver's seat, it can be easily loaded and unloaded even if the loading and unloading frequency is high. Even if it is attached to the end of a train, it does not impair the elegant shape of the entire vehicle. In particular, the flexibility of the bag body firmly holds the bag opening and the window hole surroundings of the mounting frame in close contact with each other, so that foreign matter can be prevented from entering and the rising flange of the mounting frame is connected. Since it is fitted onto the connector and firmly attached to the coupler by the latching engagement of the latch, there is no risk of foreign matter entering the air pipe end opening of the coupler without falling off during use. Its practical effect is remarkable.
