2. Description of the Related Art In order to prevent the movement of cargo during transportation, the cargo is loaded onto the body walls and cargo storage walls of container vehicles, railway freight vehicles, aircrafts, etc. using lashing belts or partition rods wrapped around lashing rails. Restrained. This lashing rail is
Since it requires strength, it is manufactured by using a steel plate or a stainless steel plate as a material, and performing bending using a press or roll forming. The use of an iron member causes the weight of a vehicle or the like to be heavy, and is not preferable for a vehicle or the like in which reduction in fuel consumption is strongly required. In recent years, lashing rails using aluminum instead of iron have begun to be used. The present inventors have also introduced a lashing rail made of extruded aluminum in Utility Model Registration No. 2539964.

[0003]

The lashing rail is
For example, in a van truck etc., it is directly attached to a heat insulating wall. The heat insulating wall 1 has a sandwich structure in which a foamed resin 1c such as urethane is filled between face plates 1a and 1b as shown in FIG. A lashing rail 2 is attached to the heat insulating wall 1 with a rivet 3, and the periphery of the rivet 3 is filled with an epoxy resin 4. However, since an aluminum plate having a thickness of about 0.8 mm is used as the face plates 1a and 1b,
When a large load is applied to the lashing rail 2, the rivet 3
Easily fall off or the face plate 1a is easily peeled off. The present invention has been devised in order to solve such a problem. By indirectly attaching a lashing rail to a face plate via a holder, the mounting portion is strongly reinforced, a rivet is dropped and the face plate is dropped. The purpose is to prevent the peeling of

[0004]

In order to achieve the object, a lashing rail mounting structure according to the present invention has a vertically extending pallet guide and a pallet guide between a holder fixed to a side wall of a carrier and upper and lower pallet guides. And a lashing rail formed with a plurality of openings for locking the tightening belt along the longitudinal direction, and the pallet guide is protruded more toward the inside of the vehicle than the lashing rail. The lashing rail is
It can also be mounted on the holder by mechanical fit. In this case, a rail receiver into which the lower part of the lashing rail is inserted is provided on the lower pallet guide, and a rail holder having a concave portion for sandwiching the inner step and the engaging projection of the lashing rail and also serving as the upper pallet guide is fixed to the rail holder. The holder is fixed to the side wall of the carrier using rivets or a combination of rivets and resin adhesive. When using a resin adhesive, a plurality of protrusions or protrusions are provided on the back of the holder so that a gap is formed between the side wall and the holder when the holder is moved along the side wall of the carrier, and the side wall and the holder are connected to each other. The gap is filled with a resin adhesive.

[0005]

In the mounting structure according to the present invention, as shown in FIG. 2, a holder 10 is mounted on a face plate 1a of a heat insulating wall 1, and a lashing rail 20 is mounted on the holder 10. The holder 10 and the lashing rail 20 are manufactured from an extruded aluminum material having a predetermined sectional shape. The holder 10 has a protrusion 11 (FIG. 2) or a raised portion 12 (FIG. 3) formed on the side facing the face plate 1a. When the holder 10 is superimposed on the face plate 1a, the protrusion 11 or the raised portion 12 forms a gap G between the holder 10 and the face plate 1a (FIG. 4).
To form The gap G is set to about 0.5 to 1 mm.
Is attached to the holder 10. For attachment of the holder 10 to the face plate 1a, a rivet 31 can be used instead of the adhesive, or the rivet 31 and the adhesive can be used together.

[0006] Pallet guides 13, 13 are provided at two locations on the front side of the holder 10 at the top and bottom. The pallet guides 13 have a hollow cross section and protrude from the front surface of the holder 10. A groove 18 (FIG. 5a) extending in the longitudinal direction of the holder 10 may be provided on the vehicle interior of the pallet guides 13 to improve the design. Holder 10
Is installed on the heat insulating wall 1, the pallet guide 1
3, 13 protrude inside the vehicle. Therefore, when a cart or the like loaded with luggage approaches the wall carelessly, the cart or the like first comes into contact with the pallet guides 13 and 13 to protect the face plate 1a and the lashing rail 20. Protrusions 14, 14 that support the lashing rail 20 from the rear side are provided between the upper and lower pallet guides 13, 13. Support projection 1
4 and 14 can be omitted when the lashing rail 20 having a large thickness is used. Projection 11, ridge 1
2, the pallet guide 13 and the projections 14 enhance the rigidity of the holder 10 in addition to the above-described functions.

[0007] The lashing rail 20 is attached to the holder 10 by rivets 32. The lashing rail 20 is manufactured by subjecting an extruded aluminum material to heat treatment and processing, and then performing a surface treatment as necessary. As a processing method, an extruded aluminum material having a cross-sectional shape shown in FIG. 5B is cut into a predetermined length, and FIG.
5 are formed along the longitudinal direction, and the edge of the opening 21 is bent as shown in FIG. 5D to form the fastening portion 22 of the tightening belt. In FIG. 2, the lashing rail 20 is attached to the holder 1 using a rivet 32.
The example of attaching to 0 has been described. However, the lashing rail 20 is not limited thereto, and the lashing rail 20 can be mounted on the holder 10 by mechanical fitting. In this case, as shown in FIG. 4, a concave portion serving as the rail receiver 15 is formed on the side surface of one of the pallet guides 13a, and the other is a rail press receiver 13b having the pallet guide portion opened.
As the lashing rail 20, one having a projection 23 fitted on the rail receiver 15 on one side and an engagement projection 24 of a similar shape on the other side is used.

[0008] As shown in FIG. 4 (a), the fitting projection 23 of the lashing rail 20 is fitted to the rail receiver 15 of the holder 10 fixed to the heat insulating wall 1 with the rivet 31, and the lashing rail 20 is directed toward the holder 10. And launch it. As shown in FIG. 4B, the lashing rail 20 has an abutting portion 25 orthogonal to the engaging projection 24 and the rail holding receiver 1.
The holder 3 is moved along the holder 10 in contact with the inner step 13c. Next, as shown in FIG. 4C, the inner step 13c and the engaging projection 24 are fitted into the recess 17 of the rail retainer 16 also serving as the other pallet guide, and the rail retainer 16 is moved upward by the rivet 33.
b. In this mounting method, the lashing rail 2
The lashing rail 20 is attached to the holder 10 by one rivet 33 without the need for riveting 0. That is, the lashing rail 20 can be attached with one less rivet than in the case of FIG.

The mounted lashing rail 20 is shown in FIG.
(A) As shown in FIG.
5 and the upper part is supported by the rail retainer 16, so that it is fixed to the holder 10 without rattling. Therefore, the force applied to the lashing rail 20 when the load or the like is restrained by hanging the tightening belt or the partition bar on the belt locking portion 22 of the lashing rail 20 is dispersed by the holder 10 without directly transmitting to the heat insulating wall 1. It is transmitted as strength. That is, since a large load is not applied to the rivets 31, 32 alone, the rivets 31, 32 are prevented from falling off and the face plate 1a is prevented from peeling off. In addition, lashing rail 2
0 is protected by the pallet guide 13a protruding inward from the vehicle and the rail retainer 13b also serving as the pallet guide, so that it is not damaged by collision or contact with the cart. Therefore, routing of the tightening belt and arrangement of the partition bar for restraining the load loaded on the vehicle can be performed without any trouble. If the pallet guide 13a or the rail retainer 13b is damaged due to collision or contact with a car, the lashing rail 20 does not need to be replaced, so that the repair cost is reduced.

[0010]

As described above, in the present invention, since the lashing rail is attached to the side wall of the carrier through the holder provided with the upper and lower pallet guides, the lashing rail is protected from collision or contact with the cart. Thus, the tightening work of the loaded luggage and the like can be performed without any trouble for a long period of time. In addition, since the force applied to the lashing rail by the tightening belt or partition bar that restrains the load is distributed by the holder and transmitted to the side wall of the carrier, troubles such as falling off of the rivets that secure the holder to the side wall and peeling of the face plate are caused. Does not occur.
