Description

  The present invention relates to a railcar cab window frame structure, a railcar wiper mounting structure, and a mounting method.

In recent years, the design of express trains has been diversified, and curved surfaces are also used around the cab. Along with such a design trend, the window shield of the driver's cab, which has been divided into a plurality of pieces in the past, has also been increasingly adopted as a large unit or a curved surface. In a driver's cab equipped with a window shield that has been enlarged in this way, a wiper for wiping off raindrops adhering to the window shield is installed in the same manner as in the past in order to secure a field of view in rainy weather.
Conventionally, a single curved window shield has been used for automobiles running on the road, not rail cars, and wipers that cover a wide range of window shields have been used, and the mounting structure has also been devised. (For example, refer to Patent Document 1).

Japanese Utility Model Publication No. 3-51662

  Now, FIG. 4 shows an example of the structure window frame bone 12 that constitutes the driver's cab 10 of the express railcar. The illustrated structure window frame bone 12 is configured by combining a plurality of structure parts 12A, 12B, 12C, and 12D cut out from a metal block material by machining. The window shield 14 is attached to the opening 12 a of the structure window frame bone 12. In the example shown in the figure, three wipers 16 are provided so that one large shield is adopted for the window shield 14 and so that a wide range of raindrops on the window shield 14 can be wiped off.

  FIG. 5 shows a front view and a plan view of the structure window frame bone shown in FIG. 4, in which the peripheral part of the structure part 12 </ b> A including the mounting seat for the component parts of the wiper 16 is extracted. As shown in FIG. 5, the structure part 12 </ b> A is provided with mounting seats 102, 104, and 106 for the wiper 16. The wipers 16A and 16C shown in FIG. 4 are fixed to the mounting seats 102 and 104, and the wiper 16B is fixed to the mounting seat 106.

In the conventional wiper mounting structure as described above, the mounting seats 102, 104, and 106 are sheet metal parts that are separate from the structural part 12A, and the shape is examined, designed, and manufactured separately from the structural part 12A. ing. Further, it is necessary to perform an operation of fixing them to the structural part 12A by welding or the like. At this time, it is necessary to sufficiently secure the mounting strength of the mounting seats 102, 104, 106 to the structural part 12A.
Moreover, if the positioning of the mounting seats 102, 104, 106 with respect to the structural part 12A is inaccurate, the operation reference point of the wiper 16 is shifted from the design position, and the smooth operation of the wiper 16 along the curved surface shape of the window shield 14 is performed. Will not be made. Such a problem becomes more prominent due to the curved shape of the window shield. For this reason, conventionally, it may be necessary to redo the positioning and fixing work of the mounting seats 102, 104, 106 with respect to the structural part 12A and the mounting work of the wiper 16 with respect to the mounting seats 102, 104, 106.

As in the conventional case (see FIG. 4), the structure window frame bone 12 is formed by combining a plurality of structure parts 12A, 12B, 12C, and 12D that are machined out of a metal block material such as an aluminum alloy, and welding. It is comprised by mutually fixing. As shown in FIG. 1, a mounting seat 22 for fixing the wiper component at a position adjacent to the window shield 14 (see FIG. 1A) of the structural part 12 </ b> A constituting the lower side of the opening 12 a, 24 and 26 (see FIG. 1B) are integrally formed.

These mounting seats 22, 24, and 26 are cut out from the metal block material 12A0 (see FIG. 3), which is the base of the structural part 12A, by a series of machining processes integrally with the structural part 12A. The three wipers 16A, 16B, and 16C shown in FIG. 1A are fixed to the mounting seats 22, 24, and 26, respectively. The other structural parts 12B, 12C, and 12D are also cut out from a metal block material suitable for cutting out the shape of each part, but the illustration is omitted.
The shapes of the contact surfaces of the mounting seats 22, 24 and 26 with the components of the wiper 16 are the conventional mounting seats 102, 104 and 106 (see FIG. 5), which are made of sheet metal parts separate from the structural part 12A. However, since it is cut out integrally with the structural body part 12A, a shape that takes into account the machining requirements is adopted. Further, the shape of each component of the wipers 16A, 16B, and 16C is the same as the conventional one (see FIG. 4). Therefore, the attachment work itself of the wipers 16A, 16B, and 16C with respect to the attachment seats 22, 24, and 26 is the same as the work with respect to the conventional attachment seats 102, 104, and 106.
