Description

  The present invention relates to a rainwater intrusion prevention structure for a van type truck door provided with a device for preventing rainwater from entering a warehouse. More specifically, the present invention relates to a structure for preventing rainwater that has entered from the top of the truck door from stopping at the top of the truck door and preventing further intrusion.

  In FIG. 5, 1 is a known van type truck. 2 is a double door opening rear door hingedly connected to the rear side column 3 of the van type truck 1. When closed, the locking rod 4 is rotated by the handle 5, and the upper cam 6 is moved to the upper frame 8 and the lower frame 9. Is engaged with the cam keeper 7 and locked. Further, when the door is opened, the handle 5 is rotated in the reverse direction to release the engagement between the cam 6 and the cam keeper 7 so that the rear door can be opened in a double-sided manner.

  Such a door of a van type truck has a rattle of the door due to torsion and vibration that the truck body receives during running of the truck. Moreover, it is difficult to adopt a structure in which a waterproof gasket attached around the door is forcibly crushed against the door frame because the door has a large door size and the rigidity of the door is low. For this reason, the lip-shaped gasket 10 (FIG. 6) is generally used by being pressed against the frame member 8.

  In the case of this lip-shaped gasket, the pressing of the gasket becomes soft due to vibration during running or torsion of the body, and rainwater soaks into the interior of the van type truck through the gap formed between the frame member 8 and the gasket 10. This may become water droplets and hang down along the inner surface of the cabinet (see symbol a in FIG. 6).

  The rainwater that has entered the water droplets in this way causes the door core material to corrode or fouls the cargo in the warehouse.

  In order to solve such a problem, in the door in which the peripheral four sides of the door are surrounded by the upper frame material, the lower frame material, and the both side frame materials, and a seal material (lip-shaped seal material) is attached to these frame materials, FIG. As shown in FIG. 2, a groove forming mold 11 separate from the upper frame member is attached to the upper inner surface of the door with a rivet 12 or the like, thereby forming a rainwater dropping groove 13 that has entered the upper portion of the door. It is known that rainwater accumulated in the door is communicated with the hollow portion 14 in the door main body, and is discharged outside through an outflow hole (not shown) provided in the bottom of the main body (see Patent Document 1). .

The rainwater dropping groove 13 to which such a separate groove forming mold material 11 is attached with a rivet 12 or the like is increased in the number of members, and thus the structure is complicated, and it is attached by the rivet 12 or the like. It was a problem in terms of work efficiency.

  The rainwater intrusion prevention structure for the van type truck door according to the present invention is a further improvement of the structure by the separate groove forming mold material according to the above-mentioned prior art, and this is performed at the time of extrusion molding of the upper frame member attached to the upper end of the door. It is an object of the present invention to provide a rainwater intrusion prevention structure for a van type truck door that has a simple structure and is excellent in preventing rainwater intrusion.

Therefore, the rainwater intrusion prevention structure for van type truck doors of the present invention is a truck in which the four sides of the door body are surrounded by frame materials, and lip seals are attached to these frame materials to prevent rainwater from entering. In the door, for the inner side of the upper frame material surrounding the upper side of the truck door, a hook-forming rising piece extending upward is formed integrally with the upper frame material,
A ridge with both ends sealed with stoppers is formed between the rising piece for forming the ridge and the inner lip piece of the lip-shaped sealing material, and a drain hole is drilled in the bottom of the ridge, and from the drain hole Rain water is discharged from the lower part of the truck door to the outside of the vehicle through the main body of the truck door.
In addition, it is desirable that the main body portion of the truck door is constituted by a combination of hollow extrusion mold materials and drains downward through the hollow extrusion mold materials. This configuration facilitates discharge from the bottom of the vehicle through the inside of the door body from the bottom of the bag.
Furthermore, it is desirable that the upper frame material of the door is made of an extrusion mold material, and the drain hole is drilled or punched at the bottom of the ridge. This greatly simplifies the configuration and can completely prevent rainwater from leaking.

  The rainwater intrusion prevention structure for a van type truck according to the present invention forms a ridge-forming rising piece on the inside of the upper frame material by integral processing at the time of extrusion molding, and the inside of the integral ridge-forming rising piece and the lip-shaped sealing material A ridge was formed between the lip piece.

  And the rainwater that has penetrated from the top of the truck door due to the twisting of the vehicle body while traveling by this dredge falls into this dredge, further propagates this dredge, and from the drain hole provided at the bottom, the door body It can pass through the inside and be discharged to the bottom.

  In this way, since the heel is composed of the ridge-forming rising piece formed integrally with the upper frame member, the configuration is simplified.

  In addition, since the body portion of the truck door is configured by a combination of hollow extrusion mold materials and drained downward through the hollow extrusion mold materials, it becomes easy in combination with the configuration of the ridges by the rising pieces for ridge formation. .

  Further, since the upper frame member is made of an aluminum extrusion mold and the water drainage hole is drilled or punched in the bottom of the ridge, the upper frame member can be easily processed or drilled.

  In addition, rainwater is discharged outside the vehicle through a discharge port drilled in the lower frame that surrounds the lower part of the truck door, making it easy to discharge from the upper frame to the lower frame and out of the vehicle. It has come to be performed smoothly with a simple configuration.

An example of an embodiment of the present invention will be described with reference to FIG.
