Description

[Detailed Description of the Invention] The present invention relates to a wing panel for a freight vehicle.

Generally, wing panels are used for freight vehicles such as freight cars, and have an L-shape, more specifically, an inverted L-shape, in vertical cross section, and are rotatable on a pivot extending longitudinally above the loading platform. A set of two covers the upper and both sides of the cargo loading space on the loading platform. By rotating this wing panel upward, the sides of the cargo platform can be opened.

By the way, in conventional wing panels, many rod-shaped sections are fixed together by welding to form a framework with an L-shaped cross section, and then the sheets are riveted together. In particular, one worker uses a riveting gun and the other worker uses a riveting gun to attach the sheets. It is made by attaching the wing panel using a riveting process in which rivets are caulked from both sides of the wing panel (hereinafter referred to as double-sided riveting process).

However, as freight vehicles become larger, larger wing panels are required, and therefore a great deal of effort, time, and expense are required to manufacture and transport the L-shaped integrated wing panels. Furthermore, when a frame with an L-shaped cross section is manufactured by welding, the finishing accuracy is poor and the appearance is poor. Furthermore, the work of driving rivets on both sides of a frame with an L-shaped cross section is troublesome and does not have good work efficiency.

In order to solve these drawbacks of the prior art, Japanese Utility Model Publication No. 55-10166 discloses a pair of L-shaped frames, an upper sheet extending between the horizontal legs of both frames, and a sheet extending between the vertical legs of both frames. Wing panels have been proposed with flared side sheets and corner members extending between the frames over the corner portions between the top sheet and the side sheets, these components being individually manufactured as separate pieces. and then fixed to each other.

However, although this fixation can be achieved at the site where it is installed on the freight vehicle, it is difficult to fix the L-shaped frame and the corner members perpendicular to it, and according to the above publication,
After a protrusion is provided on the bent portion of the frame and is fitted into the hollow portion of the corner member, a suitable fixing means is used to further fix the protrusion between the protrusions. Furthermore, it is necessary to fit the top sheet and the side sheets into the framework made up of the frame and corner members fixed to each other in this way and fix them to the framework, which requires a troublesome and difficult fixing work. There are problems such as.

In order to solve the above-mentioned drawbacks of the prior art, the present applicant proposed a wing panel for a freight vehicle as shown in Japanese Utility Model Application Publication No. 118017/1983, but the upper panel part and the side panel part do not have bones attached to the seat. Since it is a structure in which the timbers and pillars are fixed together, drilling holes, riveting on both sides, and welding are necessary to achieve this fixation, and a structure that is drilled and caulked with rivets will not last for many years of use. This caused water to enter through the rivet holes, and required many man-hours to seal the rivet holes during manufacturing.

Further, when the aggregate is fixed to the sheet by welding, since the sheet is usually a thin metal plate, there is an inherent problem that welding distortion occurs and causes dimensional errors.

Furthermore, Japanese Utility Model Publication No. 52-27523 discloses a connecting leg with a locking part at the tip of each of two panels, that is, a connecting end, and a connecting leg that is locked to the locking part when the connecting leg is in an expanded state. A technique has been disclosed in which a locked portion is provided, and when these two panels are connected, a connecting block is inserted into the connecting space in a temporarily connected state to connect the two panels.

However, with this conventional technology, although it is possible to omit the troublesome and difficult work such as drilling holes and driving rivets on both sides as in connection methods using double-sided rivets or screws, it is difficult to connect the two panels in a temporarily joined state. In addition to requiring work to insert a separate plug-in connecting block into the connector, it is also necessary to prepare a separate plug-in connecting block with a taper for expanding the connecting legs, which increases work man-hours and parts costs. There's a problem. Moreover, in this prior art, the flat plate part of the panel itself has a two-plate structure, which increases the weight, which is a problem for wing panels that need to be lightweight.

One purpose of the present invention is to provide a wing panel for a freight vehicle that can be manufactured without the need for troublesome and difficult work such as fixing the frame to the seat part or flat plate part and riveting on both sides as in the past. It is in.

Other objects and advantages of the present invention will become more apparent from the description of the specification and drawings.

By having the above configuration, the present invention can achieve excellent effects as described below.

(1) There is no need for drilling rivets, double-sided repelling work, and welding work to secure the frame of the wing panel, sheet, and flat plate as in the past, resulting in a significant reduction in the number of work hours.

(2) Since the flat plate part and the connecting member are integrated into a shape, there is no need to drill holes in the flat plate part or weld it, so there is no risk of water entering through the rivet holes in the flat plate part or distortion due to welding. It is possible to prevent dimensional errors from occurring due to

(3) Due to the above-described structure, the connecting member of the present invention is very easy to install, and does not require any special tools unless special strength is required.

(4) If there is any concern about strength, it is sufficient to insert bolts or reinforce posts only through the framework, so a considerable reinforcing effect can be expected with the minimum necessary amount.

(5) Since the flat plate portion is made of one plate, it is lightweight, which is extremely advantageous for wing panels that require vertical opening and closing operations.

(6) As described in (5) above, since the flat plate portion is made of one plate, the connecting portion by the connecting member functions extremely effectively as a frame for the wing panel, and a wing panel with high strength can be obtained. .

(7) Since no direct processing is required on the flat plate part, the appearance is good.

(8) Since it is a combination of only shape materials, mass production in factories is easy.
