Description

  The present invention relates to a connecting hood for a vehicle.

  Conventionally, as a connecting hood for a railway vehicle or the like, a plurality of annular hoods are arranged side by side, and a thin cloth hood is laid in a bellows shape between these hoods, and the hood is sewn to the hood. It is known that a fixed hood is formed by fixing.

  In addition, there is known a method in which a hood cloth is fixed to a hood bone with a presser plate and a rivet.

  In the case where the hood cloth is formed in a bellows shape with a thin cloth or the like like the above-described conventional hood for a vehicle, the rigidity of the hood cloth is poor. There is a problem that the cloth is compressed and protrudes into the passage, and wrinkles are likely to occur during normal running. In particular, wrinkles are likely to occur at the corners of the hood, and the appearance is poor.

  Furthermore, when wrinkles occur in the hood as described above, there is a problem that the hood cloth is likely to accumulate snow, snow, and freeze during snowfall.

  Further, in the case where the presser plate is made of metal, there is a problem that the presser plate is liable to accumulate snow, snow and freeze.

  Accordingly, an object of the present invention is to provide a connecting hood for a vehicle that has high rigidity, reduces the generation of wrinkles, and is unlikely to accumulate snow, snow, or freeze.

In order to solve the above-mentioned problem, the invention according to claim 1 is a connecting hood for a vehicle in which a hood portion is provided on the outer periphery of an annular hood bone and a passage is formed therein.
The hood part is formed from a single-plate base material in which a rubber material is disposed on the front and back of a stretchable base fabric, and has a hood fold that is bent in a V shape in the passage direction over the entire circumference of the passage. The V-shaped hood pleats are characterized in that the base material of the single plate is formed into a V shape by heating and pressing with a forming die.

  In the present invention, the rubber material on the front and back forming the hood part is formed into a V shape by heating and pressurizing to form the hood fold, so that the rigidity of the hood fold is enhanced.

  The invention according to claim 2 is characterized in that, in the invention according to claim 1, in which the hood bone and the hood part are fixed with a presser plate and a connecting tool, the presser plate is formed of resin. It is.

  In the present invention, since the presser plate is formed of a resin, the surface of the resin presser plate can be formed more smoothly than a conventional metal presser plate.

  As described above, according to the first aspect of the present invention, the rigidity of the hood folds is increased, and the pressure applied to the outside of the hood folds generated when passing in the tunnel or passing by the vehicle regardless of the normal running. , Prevents the hood from overhanging the passage, reduces the deformation of the hood folds when the vehicle is running, reduces the generation of wrinkles, suppresses the progress of deterioration, improves the durability, and improves the appearance Can be provided.

  Furthermore, since the front and back of the hood part are made of rubber, it expands and contracts when the vehicle travels, and it is possible to suppress snow accumulation, snowfall, and icing on the hood part.

  According to the second aspect of the present invention, since the presser plate is molded from resin, the surface thereof can be smoothed to suppress snow accumulation, snow accretion, and freezing on the presser plate.

BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described based on an embodiment shown in the drawings.
FIG. 1 to FIG. 5 show an embodiment of the present invention. FIG. 1 is a perspective view in which a portion of a hood portion in a connecting hood for a vehicle according to the present invention is broken, and FIG. 2 is a sectional view taken along line XX in FIG. 3 is a cross-sectional view of a flat state before forming the hood, FIG. 4 is a cross-sectional view of forming the hood in the state of FIG. 3 into a hood having a hood fold 12, and FIG. It is sectional drawing which attached the bone and used as the connection top.

  A connecting hood 1 for a vehicle according to the present invention includes a hood portion 2, a hood bone 3, a presser plate 4 that connects the hood portion 2 and the hood bone 3, and a rivet 5 that is a connecting tool.

  The hood portion 2 has a predetermined length in the direction of the passage C (passage direction) AB as shown in FIG. 1, and in the direction perpendicular to the passage direction AB as shown in FIG. The cross section is formed in a cylindrical shape formed in an annular shape.

  Next, the manufacturing method of the hood part 2 and the structure of a connecting hood for a vehicle using the hood part 2 will be described.

  First, as shown in FIG. 3, a sheet-like base material 9 is prepared in which rubber materials 7 and 8 made of synthetic rubber are temporarily bonded to the front and back surfaces of a stretchable base fabric 6 with an adhesive.

  Next, one mold 10 having a continuous V-shaped mold surface 10 a as shown in FIG. 4 and the other mold 11 having a V-shaped mold surface 11 a along the mold surface 10 a of the one mold 10. In a state of being separated from each other, the base material 9 is interposed between the mold surfaces 10a and 11a.

  Next, both the molds 10 and 11 are heated to a predetermined temperature, and the front and back surfaces of the base material 9 are pressurized by being brought close to each other. By this heating and pressurization, the rubber materials 7 and 8 of the base material 9 are vulcanized, and the V-shaped hood folds 12 along the mold surfaces 10a and 11a are formed by plastic deformation.

  The base material 9 has a length in a passage direction (A-B direction) that can integrally form a cylindrical hood portion 2 having a hood fold 12 as shown in FIG. 1, and the passage direction. It is formed of a single plate having a length in the orthogonal direction.

  Further, the molds 10 and 11 are arranged vertically and horizontally so as to correspond to the upper part 2a, the lower part 2b and the left and right 2c and 2d of the cylindrical hood part 2 shown in FIG. As shown in FIG. 1, the sheet-like substrate 9 as described above is disposed between the tubes 10 and 11 in a cylindrical shape, and the molds 10 and 11 are heated as described above to pressurize the substrate 9. As described above, a plurality of V-shaped hood folds 12 are continuous in the AB direction, and the V-shaped hood folds 12 are in the circumferential direction orthogonal to the AB direction. A hood portion 2 formed in a series over the entire circumference is formed.

  Next, as shown in FIG. 5, the hood bone 3 is arranged inside the top of the hood fold 12 in the hood part 2 formed as described above. The hood bone 3 is formed of a metal pipe, and is formed in a square shape when viewed from the passage direction so as to be disposed on the entire circumference of the hood fold 12.

  Next, the presser plate 4 is arranged outside the top of the hood fold 12, and the rivet 5, which is a connecting tool, passes through the hood part 2 composed of the presser plate 4 and the base material 9 from the outer side of the presser plate 4. And fix to the hood bone 3. Thereby, the hood part 2 and the hood bone 3 are fixed. The presser plate 4 is formed of a resin such as fluororesin or polyethylene, and is disposed on the top, bottom, left and right of the hood portion 2. The presser plate 4 may be provided over the entire circumference of the hood part 2.

Incidentally, the in hood portion 2 of the like Horokin frame connecting the xenon distribution and the vehicle are that provided, they are not shown.

Since it is the above structure, it has the following operations and effects.
As described above, the base material 9 is formed by arranging the rubber materials 7 and 8 on the front and back surfaces of the base fabric 6, and the base material 9 is heated and pressed into a V shape to apply a V shape hood to the hood portion 2. Since the pleat 12 is molded, the rigidity of the hood folds is increased by the V shape of the rubber materials 7 and 8, and the deformation of the hood folds 12 when the vehicle is running can be reduced. Therefore, it is possible to prevent the hood part 2 from being compressed inside the connecting hood 1 and projecting into the passage C due to a change in atmospheric pressure during traveling in the tunnel. Further, the generation of wrinkles in the hood folds 12 can be prevented and the front and back surfaces of the hood folds 12 can be formed as smooth surfaces. Therefore, the appearance of the hood part 2 is improved.

  Furthermore, since the surface of the hood part 2 is smooth and the hood part 2 expands and contracts when the vehicle travels, it is possible to suppress snow accumulation, snow accretion, and icing on the hood part 2.

  In addition, since the presser plate 4 is made of a resin having a higher molecular weight than that of metal, the surface of the resin presser plate 4 can be formed more smoothly than the surface of a conventional metal presser plate. It is possible to suppress snow accumulation, snow accretion, and freezing on the presser plate 4 as compared with the conventional metal presser plate.
