Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a truck bed.

[Conventional technology]

In a conventional truck carrier, when a tire case is attached in contact with the left and right side panels of a floor plate, a large opening as a tire space is formed in the attachment portion of the tire case.

Like the automobiles disclosed in Japanese Utility Model Laid-Open No. 61-36481 and Japanese Utility Model Laid-Open No. 57-118979, a vertical bead extending in the front-rear direction of the vehicle body is formed on a portion of the floor plate other than the mounting portion of the tire case. Although its rigidity is increased because of this, in the mounting portion of the tire case, since it is necessary to attach the flange of the tire case by spot welding or the like, the vertical bead is not formed and an opening is formed as the tire space. Because of
Its rigidity and strength are lower than those of other floor board parts.

Therefore, a patch for reinforcement is attached by spot welding or the like to the lower surface of the floor plate near the side panel of the attachment portion of the tire case.

On the other hand, a sealer was applied to the joint between the mounting portion of the tire case and the flange of the tire case on the floor plate for waterproofing and rust prevention.

[Problems to be solved by the invention]

However, in the conventional vehicle as described above, since the positioning means for attaching the patch is not provided on the floor plate of the loading platform, not only the positioning work of the patch is difficult but also the inappropriate attachment position of the patch is caused. There was a risk that the reinforcing effect would be impaired.

Therefore, as in the invention of Japanese Patent Application No. 61-181910 by the present applicant, a bead portion is provided on one of the members to be attached, and a guide recess is provided at a position corresponding to the bead portion of the other member. Although it is conceivable that the both parts are easily and surely attached by engaging the guide part and the guide recess, the difficulty of positioning work can be overcome by this, but the tire case and the floor plate in the truck bed can be overcome. It is not possible to prevent the sealer applied to the seam from being peeled off by luggage.

Therefore, there is a risk that the sealer applied for water entry or rust prevention at the seam between the floor plate of the cargo bed and the tire case may be peeled off due to movement of cargo or the like, and the waterproof and rustproof effects may be reduced.

It was devised in order to solve the above-mentioned problems of the conventional one, and makes the positioning of the patch on the floor plate of the loading platform easy and accurate, overcomes the difficulty of the positioning work of the patch, and at the incorrect position of the patch. We provide a truck bed for the purpose of preventing the deterioration of the reinforcement effect due to the mounting of the truck, and also preventing the peeling of the sealer applied to the joint between the floor board of the truck and the tire case to improve the waterproof and rust preventive effect. To do.

[Means for solving problems]

In order to achieve the above-mentioned object, the truck of the present invention applies a sealer along the seam of the bed floor plate, and in the truck bed which is provided with a patch for reinforcing the seam on the lower surface of the floor plate, in the vicinity of the seam, Form a bead equal to or slightly higher than the height of the sealer along the seam,
The patch is provided with a convex portion that fits into the bead.

[Action]

With the above configuration, the fitting position of the patch is determined by fitting the convex portion of the patch to the bead portion of the floor plate, and the sealer applied to the joint between the floor plate and the tire case by the bead portion is a sealer. It is protected and its peeling is prevented.

〔Example〕

 The present invention will be described with reference to the illustrated embodiment.

Reference numeral 1 denotes a cargo bed of the truck 2, and a plurality of vertical beads 4 extending in the front-rear direction of the vehicle body are formed on a floor plate 3 thereof.
The flange 8 of the tire case 7 for the rear wheel is attached by spot welding or the like to the tire case attachment portion 6 formed by the tire opening edge portions formed near the right and left tilt doors 5. Reference numeral 9 denotes a sealer applied to a joint 13 between the tire case mounting portion 6 and the front portion 8a and the rear portion 8b of the flange 8 of the tire case 7. In addition, a portion of the floor plate 3 near the tire case mounting portion 6 has a length substantially equal to the width of the flange 8 of the tire case 7 in the direction perpendicular to the vertical beads 4, that is, the vehicle width direction, and the height of the sealer is high. A bead 10 that is set to be equal to or slightly higher than the above is provided. Reference numeral 11 denotes a patch for reinforcing the floor plate 3, and a patch 12 having a shape substantially the same as that of the bead 10 and fitted to the bead 10 is provided in the middle thereof. Then, the patch 11 is first positioned by fitting the convex portion 12 to the bead 10 of the floor plate 3 from the lower surface thereof, whereby the patch 11 is set at an appropriate position on the lower surface of the bead 10. Then, it is attached by spot welding or the like.

[Effect of device]

As described above, in the truck bed according to the present invention, the sealer is applied along the seam of the floor board of the truck, and in the truck bed provided with the patch for reinforcing the seam on the lower surface of the floor board, the sealer is provided near the seam. Since a bead having a height equal to or slightly higher than that of the bead is formed along the seam, and the patch is provided with a convex portion that fits into the bead,
The positioning of the patch on the floor surface of the loading platform becomes easy, thereby eliminating the difficulty of positioning the patch.

Further, since the patch is accurately positioned on the floor surface of the luggage carrier, it is possible to prevent the reinforcing effect of the patch from being lowered due to an improper mounting position.

Furthermore, since the bead protects the sealer applied to the joint between the floor plate and the tire case, the sealer is prevented from peeling off due to movement of cargo, and the waterproof and rust preventive effects can be improved.

Further, since it is not necessary to provide a hole for positioning on the floor surface of the cargo bed, there is no risk of water or mud invading the floor plate upper surface from the tire side, and it is not necessary to provide a means for closing the hole.

Furthermore, since the bead can be formed at the same time as the vertical bead extending in the front-rear direction of the vehicle body, the working process for forming the bead is not increased.
