Description

  The present invention relates to a container rail member attached to a container mounted on a vehicle such as a truck, and a method of fixing the container rail member.

  As shown in FIGS. 6 and 7, in this type of container 20, in order to prevent the collapse of the loaded luggage 70, a belt shape or a beam shape for fixing the luggage 70 in such a form as to be pressed against the inner wall of the container 20. The load collapse prevention member 40 is arranged. Therefore, since it is necessary to support the load collapse prevention member 40, the pair of opposing side walls 30, 30 constituting the inner wall of the container 20 are provided at the end of the load collapse prevention member 40. A long container rail member 100 provided with a plurality of hole portions 102 to which the engaging portions 50 are engaged and connected is disposed to face. The container 20 is formed long in the depth direction so that the arrangement position of the load collapse prevention member 40 can be adjusted according to the shape, the number of loads, and the like of the load 70, and a plurality of holes 102 are formed along the depth direction. Is formed. In addition, the hole 102 functioning as the engaged portion is formed in the belt-like main body portion 104 at predetermined intervals, and after being bent once on the back surface side on both sides in the width direction of the belt-like main body portion 104, Further, a flange portion 101 protruding outward is formed, and a rivet 103 is passed through the flange portion 101 and fixed to the inner wall (each side wall 30, 30) (see FIG. 8).

  For example, when the belt-shaped load collapse prevention member 40 is disposed, the belt is fastened with a considerably large force to prevent the load collapse. When a large acceleration is applied due to sudden start, sudden stop, etc., a large load acts in the direction (inward direction) to release the engagement of the load collapse prevention member 40 due to the load. Therefore, the container rail member 100 that supports the load collapse prevention member 40 is firmly attached to the inner wall (each side wall 30, 30) of the container with an adhering force that can resist such a large inward force. It is necessary to be fixed to.

  However, when fixing with the rivet 103, the side walls 30 and 30 of the container 20 have the resin thin plate 30b sandwiched between the front and back surfaces of the resin foam 30a as shown in FIG. 8C. Since it is formed as a sandwich-structured panel and the mounting surface is thin, a sufficient fixing force cannot be exerted only by driving and fixing the rivet 103 to the flange portion 101. Therefore, as shown in FIGS. 8A and 8B, a metal panel (usually referred to as a “back panel”) 110 is interposed on the surface of the side walls 30 and 30 of the container 20, and the flange portion. 101 is laminated on the back panel 110, and a rivet 103 that penetrates the flange portion 101 is driven into the side walls 30 and 30 of the container 20 through the back panel 110. Further, another rivet 111 is driven into and fixed to the portion projecting outward so as to be substantially staggered from the rivet 103 that penetrates the flange portion 101. Therefore, in the conventional means for fixing to the thin panel 30b using the rivets 103 and 111, not only a large number of rivets 103 and 111 but also a metal panel (back panel) 110 must be interposed. Therefore, the number of members required for fixing the container rail member 100 is large, and the fixing operation is complicated. For this reason, both member cost and work cost become high.

  In this invention, an adhesive agent is apply | coated to the joint surface of a flange part and an edge part fixing member, and it adheres to the inner wall surface of a container. Therefore, the metal panel (back panel) required when performing the conventional riveting is not required, and the only member required for the fixing operation is an adhesive, which contributes to a significant reduction in member cost. Moreover, since it is only necessary to apply an adhesive and fix it directly to the inner wall surface of the container, the work process is simplified and the work cost is greatly reduced. Furthermore, the flange portion can be prevented from floating from the inner wall of the container by the protruding portion provided on the end fixing member.

  Hereinafter, the present invention will be described in more detail based on the embodiments shown in the drawings.

  1-4 is a figure which shows the rail member 10 for containers concerning this embodiment. As shown in these drawings, the container rail member 10 has a length substantially corresponding to the depth length along a pair of opposing side wall surfaces of the inner wall of a container such as a vehicle to be attached. Have.

  As shown in FIG. 1, a belt-like main body portion 11 processed with a substantially uniform plate thickness is provided at a substantially central portion in the width direction when viewed from the front, and the belt-like main body portion 11 has a predetermined interval in the longitudinal direction. A plurality of hole portions 12 are formed. The hole 12 functions as an engaged portion with which an engaging portion attached to the load collapse preventing member engages (see FIGS. 6 and 7). As described in the section of the prior art, the engagement portion 50 of the load collapse prevention member 40 has, for example, notched grooves 51 and 52 at the upper and lower ends as shown in FIG. The notched grooves 51 and 52 are engaged with the upper and lower hole wall portions of the hole portion 12 (in FIG. 1, the hole portion 12). For this reason, the hole 12 is normally formed in a substantially I-shape as shown in FIG. Moreover, as shown in FIGS. 1B, 1C, and 4, the hole 12 is formed by cutting at a predetermined position of the band-shaped main body 11 and then bending it to the back side to maintain strength. The bent piece 12a is usually formed as it is.

  On both sides in the width direction of the belt-like main body portion 11, the stepped portion 13 is formed with respect to the belt-like main body portion 11 by being bent at a substantially right angle to the back side in the same manner as the bent piece 12 a and further bent outward at a substantially right angle. It has the flange part 14 which protruded and formed through. And the back surface of this flange part 14 functions as the joining surface 14a joined to the side wall surface of a container.

  As shown in FIGS. 1B, 1C, and 4, the joint surface 14a of the flange portion 14 leaves both edges in the width direction, and the concave portion 14b for adhesive application covers almost the entire length in the longitudinal direction. It is formed in a groove shape. The adhesive is applied almost uniformly over the entire surface of the adhesive application recess 14b. Since the adhesive application recess 14b is formed over substantially the entire length in the longitudinal direction and the adhesive is applied to almost the entire surface, a large adhesion area is secured between the container side wall surface, Thereby, it becomes possible to ensure a large adhesive strength.

  However, the container rail member 10 disposed to face each side wall is used for each container due to tightening of a belt-shaped load collapse prevention member or load of load due to acceleration caused by sudden stop or sudden start. A large force is applied in the direction of peeling the rail member 10 from each side wall. Therefore, the adhesive is required to have an adhesive strength that can counteract the force applied in the peeling direction, so it is necessary to secure a large adhesive area as described above, and the characteristics of the adhesive itself are also required. Those that can exhibit high adhesive strength, for example, elastic adhesives such as urethane resin and silicon resin are preferable.

  Further, as shown in FIG. 4, it is preferable to provide a reinforcing bar member 15 between arbitrary adjacent holes 12, 12 on the back side of the band-shaped main body 11. When the crosspiece 15 is in contact with the back surface of the belt-shaped main body 11, the surface facing the side wall surface of the container is substantially the same height as the joint surface 14 a of the flange portion 14, and the surface is joined. It is formed with a thickness that functions as the surface 15a. As shown in FIGS. 2 and 4, groove-like adhesive application recesses 15 b are formed on the joint surface 15 a along the longitudinal direction thereof, that is, along the width direction of the band-shaped main body 11. Thus, the container rail member 10 is more strongly bonded by applying an adhesive to the adhesive application recess 15b and bonding the adhesive to the container side wall surface.

  A means for fixing the crosspiece member 15 to the back surface of the belt-like main body portion 11 is arbitrary, and can be formed by integral molding with the belt-like main body portion 11 or can be fixed by screwing. In this embodiment, FIG. As shown in (c), in view of the manufacturing cost, a groove-like recess 15d is also formed on the surface 15c facing the back surface of the band-shaped main body 11, and can be fixed using an adhesive. The crosspiece member 15 can be provided between all the adjacent holes 12 and 12 formed in the belt-like main body portion 11, but it is provided every other hole, or only in the vicinity of the center and the end portion in the longitudinal direction of the belt-like main body portion 11. The number of arrangement, the arrangement position, and the like can be variously set in consideration of the adhesive strength.

  As shown in FIG. 5, the surface position of the band-shaped main body 11 protrudes inward with respect to the side wall 30 when bonded to the side wall 30. For this reason, when a luggage is taken in and out, the luggage may come into contact with the end of the belt-like main body 11 and a packing box, a carriage, or the like may be caught, or an operator's clothes may be caught on the end. Therefore, at least one end of the band-shaped main body 11, particularly the end located at the loading / unloading port, is provided with the end fixing member 16 in order to prevent the end from being cut off from the surface of the side wall 30. It is preferable.

  As shown in FIGS. 3 and 5, the end fixing member 16 has a top flat portion located at the same height as the surface height of the band-shaped main body 11 when adjacent to the end of the band-shaped main body 11. 16a, and an inclined surface 16b that is inclined so that the surface height decreases as the distance from the end of the band-shaped main body 11 increases. Therefore, even if the luggage is taken in and out while the luggage and the clothes of the worker are in contact, the contact position moves smoothly along the inclined surface 16b. There is nothing.

  A portion of the top flat portion 16a of the end fixing member 16 that is on the outer side in the width direction than a portion adjacent to the strip-shaped main body portion 11 has a protruding portion 16c that is located on the flange portion 14 with the strip-shaped main body portion 11 interposed therebetween. . By positioning the protrusion 16c on the flange portion 14 and sandwiching the belt-like main body portion 11, the mounting position of the end fixing member 16 is prevented from shifting. Further, as shown in FIG. 4, the back surfaces of the top flat portion 16a and the inclined surface 16b function as a bonding surface 16d that is bonded to the side wall surface of the container. However, the bonding surface 16d is shallow with a peripheral portion remaining. A concave portion 16e for adhesive application formed in a groove shape is formed. By applying an adhesive to the adhesive application recess 16e and bonding it to the side wall surface, the protruding portion 16c is prevented from lifting the flange portion 14 from the side wall surface, and the container rail member 10 of the present embodiment is fixed. It fulfills the function of supplementing the wearing power.

  According to this embodiment, an adhesive is applied to the recess 15d between the desired holes 12 and 12 on the back surface of the band-shaped main body 11, and a suitable number of crosspiece members 15 are fixedly arranged. Next, an adhesive is applied to the adhesive application recess 14 b formed in the flange portion 14 and the adhesive application recess 15 b formed in the crosspiece member 15. Next, each joining surface 14a, 15a is pressed and fixed to a predetermined position on the inner wall of the container, for example, a substantially central position in the height direction on the surface of the side wall 30 (see FIG. 1C). Next, an adhesive is applied to the adhesive application recess 16e formed on the end fixing member 16, and the protrusions 16c and 16c are adjacent to the end of the belt-shaped main body 11 located on the baggage entrance / exit side. It arrange | positions so that the strip | belt-shaped main-body part 11 may be pinched | interposed, and the bonding surface 16d may be pressed and fixed to the side wall surface (refer FIG.4 and FIG.5). After that, it waits for the adhesive to harden. In this embodiment, since it adheres to a side wall surface using an adhesive agent in this way, the rail member 10 for containers can be attached very simply and at low cost. In the above description, the end fixing member 16 is only provided at one end of the band-shaped main body 11, but may be disposed at the other end as necessary. Moreover, although the crosspiece member 15 is preferably provided as in the above embodiment, it is of course not essential.

  The rail member for containers of this invention has the recessed part for adhesive application in the joint surface of a flange part, and can adhere to the inner wall surface of a container using an adhesive agent. Therefore, the metal panel (back panel) required when performing the conventional riveting is not required, and only the adhesive is required for the fixing work, so that the member cost can be greatly reduced. . Moreover, since it is only necessary to apply an adhesive and fix it directly to the inner wall surface of the container, the work process is simplified and the work cost is greatly reduced. Furthermore, the flange portion can be prevented from floating from the inner wall of the container by the protruding portion provided on the end fixing member.
