[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention utilizes a window plate for a vehicle having a laminated structure or a multi-layer structure in which transparent plates on the outer side of the vehicle and transparent plates on the inner side of the vehicle are alternately projected in the vicinity of two opposite sides, and the projecting portions thereof. The present invention relates to a vehicle window structure attached to a vehicle body frame. This technique is particularly useful in the field of railway vehicles traveling at high speed.

[0002]

[Prior art]

 In the window structure of ordinary railroad cars, the periphery of the window plate is fixed with a frame, and the metal fittings are pressed at a position slightly inside the part. However, in such a structure, since the outer circumference of the vehicle body is uneven, wind noise is likely to occur, and aerodynamic characteristics are poor, so that it is unsuitable as a window structure for a vehicle traveling at a high speed. Therefore, it has been desired to improve the smoothing so that the surface of the window and the surface of the vehicle body become the same.

An example of such a smoothed vehicle window structure is disclosed, for example, in Japanese Utility Model Application Laid-Open No. 64-32212. There, a structure is used in which the entire circumference of the end of the window plate has a stepped structure, and the cutout step portion is fitted to the vehicle body frame so that it is sandwiched between the vehicle body frame and a metal fitting inside the vehicle body. Has been adopted.

Another example of the smoothed vehicle window structure is a structure currently put into practical use in Europe. Similar to the above, it has a stepped structure around the entire edge of the window plate, with the notched steps facing the inside of the car, and filling the entire inside step of the window plate with structural adhesive. As a result, the structure is adhered to the body frame.

[0005]

[Problems to be solved by the device]

 However, the former holding structure with a holding metal has a problem that the strength around the window plate decreases. This is because the body frame is inserted in the stepped part around the window plate, so the window thickness (glass thickness) around the stepped part becomes thin, the glass easily bends, and the stress generated in the glass increases. Because. In some cases, the generated stress may exceed the allowable stress of the glass. If the glass is thickened to reduce the stress generated in the glass, another problem arises in that the window weight increases. Further, the pressing member must have sufficient rigidity, but in order to make the outer surface of the vehicle body flush with the outer surface of the window, the pressing member must be made thinner than the step difference of the window plate. , Therefore, the rigidity becomes weak and it becomes easy to bend.

Further, in the latter structure in which the entire inner step portion of the window plate is filled with the adhesive, the adhesive performance between the window plate and the vehicle body frame is deteriorated, and the adhesive and the glass may be peeled off. Although the entire circumference of the window plate is pressed by a structural adhesive, the adhesive area is wide due to the deterioration of the adhesive due to the light and heat transmitted through the window plate and the strength of the window plate step. This is because the single-layer adhesive structure that cannot be removed and is filled in the entire stepped portion cannot withstand a large positive and negative wind pressure repeatedly applied to the window plate, and peeling occurs.

An object of the present invention is to mount a window plate on a vehicle body smoothly, ensure sufficient mechanical strength of the window plate and a mounting portion, and have excellent durability for a long period of time. A window plate and a vehicle window structure are provided.

[0008]

[Means for Solving the Problems]

 The present invention is a vehicle window plate in which a plurality of window transparent plates are laminated or laminated, and the transparent plate outside of the vehicle has two sides facing each other at the ends of the transparent plate inside the vehicle. This is a combination in which the transparent plate on the inside of the vehicle protrudes from the edge and the remaining two adjacent sides of the transparent plate on the inside of the vehicle project beyond the edge of the transparent plate on the outside of the vehicle.

The present invention also arranges the above-mentioned vehicle window plate so that the protruding portion of the transparent plate outside the vehicle is positioned in the left-right direction, and structures the inside of the protruding portion of the transparent plate outside the vehicle. It is a vehicle window structure that is adhered to the vehicle body frame with a vehicle adhesive and is fixed by pressing the outside of the protruding portion of the transparent plate inside the vehicle body from the outside.

[0010]

[Action]

 The window plate is fixed to the vehicle body frame by utilizing the upper, lower, left, and right protruding portions thereof. This fixing is usually done with a structural adhesive. With respect to the positive and negative wind pressures received while the vehicle is traveling, the pressures in the wind pressure direction are mainly supported by the overhanging upper and lower sides or the left and right sides. Since the thickness of the overhanging portion is the thickness of the window transparent plate itself, it has sufficient mechanical strength, and the frame on the outside of the vehicle can also be thickened to provide a strong bond.

【Example】

 FIG. 1 is a perspective view showing an embodiment of a vehicle window plate according to the present invention, and FIG. 2 is a horizontal sectional view thereof showing an example of a multi-layer structure. The vehicle window plate 10 is formed by disposing window transparent plates 14 and 16 on both surfaces of a rectangular frame-shaped multi-layer spacer 12 and combining them. The transparent plates 14 and 16 are made of glass, organic glass, or a combination thereof. The multi-layer spacer 12 is for separating the transparent plates 14 and 16 from each other, and has a structure in which a desiccant is contained in a mold material made of aluminum or the like although not shown. The multi-layer spacer 12 and the transparent plates 14 and 16 are sealed by a sealing structure made of a structural adhesive and butyl rubber. The reason why such a multi-layer structure is used is to improve the heat insulation performance and sound insulation performance mainly by providing an air layer between them. One transparent plate is on the outside of the vehicle and the other transparent plate is on the inside of the vehicle. However, for the sake of convenience, the description will be continued below with the transparent plate 14 on the outside and the transparent body 16 on the inside.

In the present invention, the vicinity of two opposite sides (two sides, left and right) of the transparent plate 14 on the outside of the vehicle protrudes beyond the edge of the transparent plate 16 on the inside of the vehicle, and the transparent plate 16 on the inside of the vehicle faces each other. The two sides (upper and lower two sides) facing each other are combined so as to project beyond the edge of the transparent plate 14 outside the vehicle. Therefore, the shape and size of the multi-layer spacer 12 substantially correspond to the contour shape in which both transparent plates 14 and 16 overlap. Then, the protruding portions 14a and 16a of the respective transparent bodies 14 and 16 become the mounting portions to the vehicle body.

FIG. 3 shows how the vehicle window plate 10 is attached to the vehicle body. FIG. 3 shows the state as viewed from the outside of the vehicle. Usually, the protruding portion 14a of the transparent plate 14 on the outer side of the vehicle is arranged so as to be positioned to the left and right. A cross section in the X direction in the attached state is shown in A of FIG. 4, and a cross section in the Y direction is shown in B of FIG. In the X direction, the transparent plate 14 outside the vehicle is located outside the vehicle body frame 20, and the overhanging portion 14a of the transparent plate 14 and the vehicle body frame 20 are bonded with a structural adhesive 22. As the structural adhesive, for example, a silicone-based, urethane-based or polysulfide-based elastic adhesive is preferable. It is preferable to form a light shielding layer 18 on the inside of the overhanging portion 14a of the transparent plate 14 on the outer side of the vehicle in order to prevent the structural adhesive 22 from being deteriorated by ultraviolet rays. For example, masking treatment is performed by applying an opaque ceramic coating or baking a ceramic paste. Further, in the Y direction, the vehicle body frame 20 is arranged outside the overhanging portion 16a of the transparent plate 16 on the inner side of the vehicle, and is bonded and fixed by the structural adhesive 22 as in the X direction.

Here, it is preferable that the structural adhesive 22 is applied in several lines in a row as shown in the drawing. Here, the structural adhesive 22 is applied and adhered in three rows (triple) in the X direction and in two rows (double) in the Y direction. While the vehicle is running, positive and negative wind pressure is applied to the vehicle body due to passage through the tunnel and passing. This also causes the window plate to bend, but if you apply the adhesive separately to several pieces as described above, each will deform independently and the bending of the window plate can be absorbed comfortably. The reason is that peeling of the adhesive is less likely to occur.

The transparent plate 14 and the vehicle body frame 20 may be coupled in the X direction only by holding the transparent plate 14 with an elastic spacer (eg, rubber or sponge), but in terms of strength, as described above. It is preferable to bond the entire circumference with the structural adhesive 22.

5 and 6 show another embodiment of the present invention, which is an example in which a vehicle window plate 30 has a mating structure. As shown in FIG. 5, the vehicle window plate 30 has a structure in which a transparent plate 34 on the vehicle exterior side and a transparent plate 36 on the vehicle interior side are joined and integrated via a transparent intermediate film 32. Also in this case, the vicinity of the two opposite sides (two sides on the left and right) of the transparent plate 34 on the outside of the vehicle projects beyond the edge of the transparent plate 36 on the inside of the vehicle, and the two opposite sides of the transparent plate 36 on the inside of the vehicle. The combination is made so that the vicinity (upper and lower two sides) extends beyond the edge of the transparent plate 34 outside the vehicle. Therefore, the transparent intermediate film 32 corresponds to the entire overlapping portion of the transparent plates 34 and 36. Also in this case, the overhanging portions 34a and 36a of the transparent bodies 34 and 36 become the mounting portions to the vehicle body.

The attachment structure of the vehicle window plate 30 to the vehicle body may be the same as that of the multi-layer structure. The transparent portion 34a on the outer side of the vehicle is arranged so that the projecting portions 34a are located on the left and right. A cross section in the X direction in the mounted state is shown in FIG. 6A, and a cross section in the Y direction is shown in FIG. 6B. In the X direction, a transparent plate 34 outside the vehicle is located outside the vehicle body frame 40, and the protruding portion 34a of the transparent plate 34 and the vehicle body frame 40 are bonded with a structural adhesive 42. A light shielding layer 38 is formed on the inner side of the protruding portion 34a of the transparent plate 34 on the outer side of the vehicle in order to prevent the structural adhesive 42 from being deteriorated by ultraviolet rays. Further, in the Y direction, the vehicle body frame 40 is arranged outside the projecting portion 36a of the transparent plate 36 on the inner side of the vehicle, and is bonded and fixed by the structural adhesive 42 as in the X direction. Also in these cases, the structural adhesive 42 is applied in several rows in a row.

FIG. 7 shows an example of how the vehicle window plate 10 is mounted on a high-speed railway vehicle. The window plate 10 for a vehicle can be made continuous by arranging the protruding portions of the transparent plate 14 on the outer side of the vehicle so as to be located on the left and right sides and arranging so that the adjacent edges are almost in contact with each other. The portion indicated by the dotted line is the protruding portion 16a of the transparent plate on the inner side of the vehicle, and is the portion that is held by the vehicle body frame from the outer side of the vehicle. Therefore, this portion cannot be seen from the outside of the vehicle. When the glass is continuous in this way, the reflected image becomes beautiful, and a vehicle with sophisticated design can be designed and manufactured.

[0019]

[Effect of device]

 Since the present invention is a window plate of a combined structure or a multi-layer structure in which the two sides facing each other are alternately projected as described above, both the positive and negative wind pressures received while the vehicle is traveling are compared with each other. The upper and lower sides or the left and right sides of the transparent plate support the pressure in the respective wind pressure directions, which allows for firm fixing and does not reduce the strength of the window plate and its mounting portion. In addition, since the thickness of the frame outside the vehicle can be increased, the rigidity of the vehicle body frame (holding metal) is increased and bending (deflection) is reduced. Particularly in the case of a multi-layer structure, the thickness of the vehicle body frame can be increased by the distance between the transparent plate on the outside of the vehicle and the transparent plate on the inside of the vehicle, so that the effect of increasing the rigidity is further increased.

Further, as described above, since the transparent plates on the outer side of the vehicle and the transparent plates on the inner side of the vehicle alternately project in the vicinity of the two opposite sides, the projecting portion can secure the necessary strength and can secure the projecting length to some extent. . Therefore, the window plate and the vehicle body frame can be bonded to each other in a row, so that the deterioration of the bonding performance can be prevented and the reliability of the bonding for a long time can be improved. Further, since the window plates can be continuously arranged in the lateral direction, the reflected image can be seen clearly and a vehicle excellent in design can be designed and manufactured.
