Description

  The present invention relates to a wall mounting surface of a box-type carrier for a vehicle, for example, a box-type carrier for a vehicle that divides a part of a cargo compartment by a partition panel into a plurality of rooms and transports various types of cargo. The present invention relates to a structure for attaching a lashing rail for cargo binding.

  2. Description of the Related Art A rectangular parallelepiped box-shaped loading platform having a roof and hermetically sealed is widely used as a loading platform for trucks that are vehicles for cargo transportation. The box-type loading platform has the advantage that cargo damage due to wind and rain can be prevented, packaging can be simplified, and cargo collapse can be easily prevented. In the field of freight transportation by trucks, etc., there is an increasing demand for the transportation of perishable cargo such as fresh foods such as vegetables and seafood, or frozen products. A constant temperature transport vehicle (temperature control vehicle) is used which is equipped with a box-type cargo bed and maintains the temperature of the cargo compartment at a constant temperature by a refrigeration apparatus or the like.

  Recently, from the perspective of pursuing convenience such as small delivery, a box-type cargo bed is equipped with refrigeration and refrigeration equipment, and a partition panel is arranged in the cargo compartment to divide it into multiple rooms. Box-type cargo beds called multipurpose vans that carry cargo are also commonly used. This box-type loading platform stores room temperature storage rooms that are not temperature-controlled (hereinafter sometimes referred to as “dry rooms”), refrigerator rooms that are suitable for storing refrigerated products, and refrigerators that are colder than room temperature. A freezer room having a room temperature lower than that of a refrigerator compartment suitable for carrying out is installed, and frozen goods and refrigerator goods can be transported simultaneously with normal cargo.

  Conventionally, it is known to use a lashing belt as a load holding member used to prevent unintentional movement of a load when a load is loaded on a box-type loading platform. As shown in FIG. 1 (a), a cross-sectional hat-shaped shape (see FIG. 4) in which a plurality of locking holes 10 for locking the end portions of the lashing belt are provided in the left and right inner wall portions 120 of the cargo compartment. A lashing rail LR is attached.

  Here, as shown in FIG. 1B, in the case of providing a partition wall 100 that divides the cargo compartment of the box-type cargo bed into the front and the rear so that the front side of the box-type cargo bed is a refrigeration chamber and the rear side is a dry chamber. The outer periphery of the partition wall 100 is formed of a cushioning material made of a foamed resin material, so that the uneven shape of the inner wall portion 120 is absorbed and a gap is not generated between the inner wall portion 120 as much as possible. ing. However, when the partition wall 100 is positioned in contact with the lashing rail LR, the cold air is refrigerated forward via the clearance inside the hat-shaped cross section of the lashing rail LR and the locking hole 10 where the locking metal fitting of the lashing belt is locked. There is a problem in that it is difficult to keep the temperature of the refrigerator compartment constant by allowing the chamber and the rear dry chamber to communicate with each other and cold air leaking into the dry chamber (see FIG. 8A).

  In order to solve the above-described problem, when the partition wall 100 is positioned at a desired position in the box-type loading platform, as shown in FIG. 8B, on the lashing rail LR where the partition wall 100 is positioned. It is easy to keep the temperature of the refrigeration (or freezing) room constant by inserting a flexible insert material 140 into the locking holes 10 located before and after the door to prevent the cold air in the room around the partition wall 100 from communicating. Attempts have been made (see, for example, Patent Document 1).

Japanese Patent No. 4599151

  Since the insert member 140 shown in FIG. 8B is inserted into the locking hole 10 to close the hole, when the partition wall 100 is moved in the front-rear direction, the insert member 140 currently inserted is inserted. It is necessary to take out from the locking hole 10 of the lashing rail LR and newly insert it into another locking hole 10 in accordance with the position of the newly set partition wall 100. In particular, when applied to the configuration as shown in FIG. 1B, there are four lashing rails LR, and two inserts 140 are required before and after the partition wall 100. Therefore, it is necessary to take out the insert material 140 and insert the insert material 140 again at the front and rear positions corresponding to the new position. When the position of the partition wall 100 is changed, extremely complicated work is required.

  In addition, when the insert material 140 described in FIG. 8B is used, the lock hole 10 for originally locking the metal fitting for the lashing belt is blocked by the insert material 140. The locking hole 10 cannot be used as a locking hole for fixing the load, and as shown in FIG. 1B, to fix the partition wall 100 to the inner wall portion 120. Even when the lashing belt 110 is used, the locking holes 10 at the front and rear positions of the lashing belt 110 are blocked by the insertion of the insert material 140, so that there is a problem that fixing of the partition wall 100 is hindered.

  Furthermore, when the partition wall 100 as described above is not used and the cargo room of the box-type loading platform is used in one room, the insert material 140 becomes unnecessary, and therefore the insert material 140 causes the lashing rail LR to be used. In order to prevent the locking hole 10 from being blocked and hindering the cargo tightening by the lashing belt, the insert material 140 is tried to be stored in another place, and as a result, the insert material 140 is lost. obtain.

  An object of the present invention is to provide a partition wall in a box-type cargo bed, and when the box-type cargo bed is divided into a plurality of cargo compartments, there is a problem in locking the lashing belt when loading and fixing the partition wall. It is another object of the present invention to provide a lashing rail mounting structure that prevents the air in each cargo compartment from circulating through a gap in the lashing rail without forcing the user to perform complicated operations.

In order to solve the above problems, the present invention is a hat-shaped cross section provided with a plurality of locking holes that are attached to the mounting surface of the inner wall portion of the box-type cargo bed for vehicles and that lock the ends of the load holding members.
