Description

  The present invention relates to a wood floor material suitable for a vehicle as a cargo bed floor for a load carrying vehicle such as a truck.

  Conventionally, as a wooden floor material used for a loading platform of a vehicle such as a truck, a floor material made of sawn timber or plywood has been widely adopted, and as its structure, for example, as shown in FIG. A large number of sawn timbers arranged side by side in the horizontal direction and joined to each other in the longitudinal direction opposite to each other, or a plurality of plywoods joined in advance with a scarf joint or the like as shown in FIG. One made of a single plywood is known.

  According to the former wooden flooring, a large number of small and long floorboard pieces are combined and mounted on the loading platform, so it takes a lot of labor and labor, and secures a high-quality lumber product free from defects such as knots and rot. There is a problem that it becomes difficult year by year and is not suitable for mass production.

  On the other hand, in the latter case, the seam is not conspicuous because it is formed of a single piece of plywood, and there is an advantage that what is manufactured in the factory can be attached to the carrier as it is, but when attaching to the carrier, the wooden flooring When a perforation process for attaching to the outer peripheral frame of the loading platform is performed on the periphery of the floor, if a processing defect occurs, the entire flooring material may become a defective product. In addition, because the size of the loading platform varies greatly depending on the manufacturer and vehicle type, there is a problem of securing a storage place and increasing the cost by having a stock for each vehicle type because it is low-volume production with a large variety of products and low production efficiency.

  As a means for solving these problems, as shown in FIG. 7 (Patent Document 1), it consists of a combination of one central wooden floor board 11 and a pair of left and right side wooden floor boards 12 arranged on both sides thereof. A wooden flooring A for vehicles has been proposed. Since it is a combination of three plywoods, labor and labor are reduced, and by combining a small amount of floor boards, it can be used for various types of loading platforms.

Further, as shown in the cross-sectional view of FIG. 8, female seeds 13 are formed on both longitudinal end faces of the central wooden floor board 11, while the side wooden floor board 12 has the center on either side end face in the longitudinal direction. A male fruit 14 that can be fitted to the female fruit 13 of the wooden floor board 11 is formed. The side wooden floorboards 12 are cut into a predetermined size according to the size of the loading platform, the real parts of the floorboards are joined on the loading platform, and drilling is performed for attaching to the outer peripheral frame of the loading platform. Even if the drilling process fails at this time, only the side wooden floor 12 is replaced, so that the waste of replacing the whole can be eliminated.

In addition, there are provided a real part that fits to both end faces in the longitudinal direction of the central wooden floor board and one side end face in the longitudinal direction of the side wooden floor board, and a joint joint portion in which the real parts are joined and integrated is sealed. It is characterized by becoming.

  According to a second aspect of the present invention, there is provided a female fruit on both longitudinal end faces of the central wooden floor board of claim 1 and one longitudinal end face of the side wooden floor board, and the female seeds are opposed to each other. It is characterized in that it is formed by sealing a joint joint which is actually joined and integrated.

  Furthermore, the invention according to claim 3 is characterized in that the central wooden floor board according to claim 1 or 2 is obtained by joining and integrating a plurality of unit boards in advance.

  According to the invention which concerns on Claim 1, while providing a real part in the one end surface of the longitudinal direction of the longitudinal direction of the center wooden floor board and the longitudinal direction of the said side wooden floor board, the joint joint part which joined and integrated the said real parts As the truck is sealed, the tires roll up water when the truck runs in the rain to wet the lower part of the loading platform and prevent water from entering from the joint joint between the central wooden flooring and the side wooden flooring to the loading platform. In addition, the combination of the central wooden floorboard and the side wooden floorboard can be used for various variations by many manufacturers and models.

  Further, according to the invention described in claim 2, while providing the female fruit on both end faces in the longitudinal direction of the central wooden floor board according to claim 1 and one end face in the longitudinal direction of the side wooden floor board, Since the joint joints that are actually joined and integrated with each other are sealed, the convex portions such as males are eliminated from the floor board, and the risk of breakage during transportation and handling is reduced.

  Further, according to the invention described in claim 3, since the central wooden floor board described in claim 1 or 2 is formed by joining and uniting a plurality of unit boards in advance, water enters from the joint between the unit boards. For example, the performance of the unit plate can be changed for each part depending on the use situation, for example, a hard plate is used for the unit plate disposed at the rear of the loading platform where wear resistance is required for loading the load. .

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Note that the present invention is not limited to the description of the present embodiment.

  First, a vehicle wood flooring A according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. The vehicle wood flooring A is composed of a central wood floor board 1 and side wood floor boards 2.

  The central wooden floor board 1 is arranged in the central part of a vehicle bed, and a commercially available plywood having a general size is used as a unit board (1a, 1b, 1c. The necessary number is joined and integrated so as to obtain a desired size according to the above. As a joining method, a commonly used scarf joint (a plain scarf, a V scarf or the like) is used, and after joining, it can be used as a single plywood in terms of strength and appearance. In FIG. 1, three unit plates (1a, 1b, 1c) are used, but the number of units can be appropriately changed according to desired dimensions.

  The unit plates (1a, 1b, 1c, etc.) are made of wood boards such as plywood, laminated wood, LVL, LVB, etc. In general, considering the strength required for use as a loading platform for vehicles, A specific gravity of 0.75 or more is required. However, the tree species used in the present invention is not particularly limited, and it is not limited to South Sea wood such as Apiton, which has been conventionally used as a suitable material for vehicles, but also planted trees (eucalyptus, larch, acacia man) that are friendly to the global environment. Can be used widely.

  In general, planted trees grow fast, but have the disadvantage that the material is soft and easily damaged. However, the unit plate placed at the rear of the loading platform, which requires wear resistance for loading cargo, corresponds to 1c in FIG. ) Can be dealt with by using a particularly hard material, the planted trees that have been difficult to use can be easily used in the method of the present invention in which the unit plates are joined and integrated.

  On the other hand, the side wooden floor boards 2 are disposed on both sides of the central wooden floor board 1, and are cut into a desired width so as to be narrower than the width of the central wooden floor board 1. By combining multiple sets of a combination of multiple types of side wooden floorboards 2 with a single type of central wooden floorboard 1 to cover a small to large platform, It can also handle variations of loading platforms.

  As shown in FIG. 2, the center wood floor board 1 and the side wood floor board 2 are joined. A female fruit 3 is provided on both sides in the longitudinal direction of the central wooden floor board 1, and a male fruit 4 fitted to the female fruit 3 is provided on one end face in the longitudinal direction of the side wooden floor board 2. However, the present invention is not limited to this, and a female fruit may be provided on the central wooden floor board side and a male fruit may be provided on the side wooden floor board side.

  As a method of attaching the central wooden floor board 1 and the side wooden floor board 2 to the truck bed, although illustration is omitted, a joist is assembled on the frame of the vehicle, and the central wooden floor board 1 and the side wooden floor board 2 are mounted on the joists. At the same time, the real parts of the floor boards are fitted together, bolt holes are formed in the side wooden floor boards 2, and bolts are fixed to the joists to construct the floor boards on the loading platform.

  Thereafter, the joint material 5 formed from the male fruit 4 and the female fruit 3 is filled with a sealing material 6 to perform waterproofing of the joint part. The sealing material 6 is not particularly specified as long as it is normally used as a joint treatment for a wooden material, but a urethane-based or silicon-based sealing material is used. If the joint joint portion 5 is too wide, it tends to deteriorate, and if it is too narrow, it cannot follow the movement of the floor board and easily breaks.

  Next, the vehicle wood flooring A according to the second embodiment will be described with reference to FIGS. 1, 3, and 4. In this configuration, female berries 3 are provided on both sides in the longitudinal direction of the central wooden floor board 1 in the same manner as described above, and female berries 3 are provided on one end face in the longitudinal direction of the side wooden floor board 2 instead of male fruit. The central wooden floor board 1 and the side wooden floor board 2 are joined together. As the last 4, a resin molded body such as polypropylene, polyethylene, polyvinyl chloride, and olefin is used.

  By changing the joining method from male and female to real, only the female fruit (groove) is provided as the floor board, so there is no male fruit (protruding part) and it is possible to prevent actual damage during transportation and handling. In addition, since it is actually made of resin, it is excellent in waterproofness, and when sealing, the sealing material adheres only to the wooden floor part, and the real part is difficult to adhere, thus preventing three-sided adhesion, and joints It becomes difficult to cut.

The wood floor material for vehicles according to the present invention having excellent waterproofness is extremely useful and has high industrial applicability because it can cope with variations of a variety of cargo beds with a small number of floor boards.
