The present invention relates to a luggage compartment structure to which a cargo compartment cushioning material such as a transport truck is attached . And the luggage compartment structure concerning the present invention has the following some features in order to achieve the above-mentioned object. That is, the luggage compartment structure of the present invention includes the following features alone or in combination as appropriate.

The first feature of the cargo compartment structure according to the present invention for achieving the above object is that a cargo compartment cushioning material comprising a foamed resin layer and a resin sheet laminated so as to cover one surface of the foamed resin layer is attached. The resin sheet is laminated such that at least a part of the edge extends out of the surface of the foamed resin layer and extends out of the surface of the foamed resin layer of the resin sheet. The protruding portion is arranged along the inner wall of the cargo compartment and is directly fixed to the inner wall by an attachment member .

According to this configuration, the surface of the foamed resin layer extends out of the plane with the surface opposite to the surface on which the resin sheet of the foamed resin layer is laminated against the cargo compartment wall to which the cushioning material for the cargo compartment is attached. By sandwiching and fixing a part of the resin sheet between the mounting member and the cargo compartment wall , the cargo cushioning material can be attached to the cargo compartment wall without using an adhesive. In this case, the mounting member is disposed on the portion of the resin sheet that extends out of the plane of the foamed resin layer, and the mounting member is not disposed on the surface of the foamed resin layer that serves as a cushioning material. Can be prevented from contacting the mounting member. Further, it is not necessary to perform complicated processing on the foamed resin layer, and it can be easily produced.
Further, a second feature of the cargo compartment cushioning material according to the present invention is that the attachment member extends in the depth direction on the side wall of the cargo compartment, and one end of a belt for fixing the cargo in the cargo compartment is attached. The extending length of the portion of the resin sheet that extends out of the surface of the foamed resin layer is within the width of the lashing rail.

Moreover, the 3rd characteristic in the shock absorbing material for luggage compartments which concerns on this invention is that the said resin sheet is formed as a rectangular-shaped sheet | seat, and the edge part of at least one side extends out of the surface of the said foamed resin layer. It is that they are laminated.

  According to this structure, the whole edge part of the one side extended out of the surface of the foamed resin layer in the resin sheet can be sandwiched and fixed between the mounting member and the mounted member. As a result, the cargo space cushioning material can be attached to the attached member in a stable state, and loosening of the cargo space cushioning material due to vibration during transportation, cargo collision, or the like can be prevented.

Moreover, the 4th characteristic in the shock absorbing material for luggage compartments which concerns on this invention is the said resin sheet. At least 1 set of edge part is extended out of the surface of the said foamed resin layer among the edge parts of two opposite sides. It is that it is laminated.

  According to this structure, the whole edge part of two opposing sides extended out of the surface of the foamed resin layer in the resin sheet edge part can be inserted | pinched between an attachment member and a to-be-attached member, and can be fixed. As a result, both ends of the shock absorber for the cargo compartment are fixed to the mounted member, so that it can be attached in a more stable state, and loosening of the shock absorber for the cargo compartment due to vibration during transportation, collision of the load, etc. Can be prevented.

The fifth feature of the cargo compartment cushioning material according to the present invention is that the foamed resin layer is disposed on the inner surface of the cargo compartment on the surface opposite to the surface on which the resin sheets are laminated. wherein a temporary fixing portion for temporarily secured to the inner wall without using the mounting member, the temporary fixing portion for fixing to is that it is intended to adhere to the inner wall.

According to this configuration, when mounting the luggage compartment cushions the luggage compartment walls, temporarily luggage compartment cushions without using the mounting member is temporarily fixed to the luggage compartment walls, and in this state, by mounting member It is possible to perform permanent fixing which is fixed. This eliminates the need for the operator to support the loading chamber cushioning material according to the mounting position of the loading chamber wall when the main fixing is performed, thereby reducing the work burden required for mounting and reducing the mounting cost. It is. In addition, it is possible to suppress positional deviation during the main fixing.

Moreover, the 6th characteristic in the shock absorbing material for luggage compartments which concerns on this invention is that the said temporary fixing part is formed by sticking a double-sided tape on the said foamed resin layer.

According to this configuration, the temporary fixing portion can be easily formed by sticking the double-sided tape to the foamed resin layer. Also, after pasting the double-sided tape on the foamed resin layer, a cover sheet that can be easily peeled off at the time of use is pasted so as to cover the sticking surface on the side of the double-sided tape to be stuck to the cargo compartment wall When transporting the cargo storage cushioning material, it does not stick to other members, and the cover sheet can be peeled off during use.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a cargo space cushioning material 100 according to an embodiment of the present invention. 2 is a front view of the cargo-chamber cushioning material 100 (viewed from the resin sheet 2 side), FIG. 3 is a rear view, FIG. 4 is a left side view, and FIG. 5 is a plan view. 6 is a cross-sectional view taken along the line AA in the rear view shown in FIG. 3, and FIGS. 7 and 8 are enlarged views of the BB part and the CC part in FIG. 6, respectively.

  The cargo space cushioning material 100 is formed by laminating the foamed resin layer 1 and the resin sheet 2, and for example, by attaching to the cargo room wall of a truck, a load such as an empty can or a plastic bottle can be directly applied to the inner wall. It is a wall board for preventing contact and preventing damage to the load.

  The foamed resin layer 1 may be, for example, a plate having a thickness of 8 to 15 mm and formed of foamed polyethylene. Moreover, the resin sheet 2 can use the olefin-type sheet | seat of thickness 0.5mm, for example. Further, the foamed resin layer 1 and the resin sheet 2 are formed in a rectangular shape, and are laminated so that the edges 2 a and 2 b of the two opposite sides of the resin sheet 2 extend out of the surface of the foamed resin layer 1. (See FIG. 1).

  The length of the foamed resin layer 1 in the vertical direction shown in the rear view of FIG. 3 is about 600 to 800 mm. Moreover, the length (ya, yb in FIG. 3) of the part extended out of the surface of the foamed resin layer 1 in the resin sheet 2 is about 50 mm. The length of the extended portion is preferably at least twice the thickness of the foamed resin layer 1 in order to stably fix the cushioning material 100 for the luggage compartment. In order to prevent the extended portion from protruding from the lashing rail when fixed, the lengths ya and yb of the extended portion are preferably within the width of the lashing rail. In addition, the cargo space cushioning material 100 is obtained by cutting the cushioning material formed in a continuous state in the left-right direction in the front view of FIG. 2 and the rear view of FIG. 3 in a direction perpendicular to the continuous direction, It has a predetermined length. Further, in the buffer material formed in a continuous state, the cross-sectional shape at an arbitrary position in the continuous direction is the same as that in FIG. 6 (FIGS. 7 and 8 in the enlarged view of the end portion). Accordingly, a right side view (not shown) of the cushioning material 100 for the cargo compartment is symmetrical to the left side view of FIG. Further, the bottom view (not shown) is a diagram that is vertically symmetrical with the plan view of FIG.

  Lamination of the foamed resin layer 1 and the resin sheet 2 can be performed, for example, by thermal welding. In this case, the resin sheet 2 is laminated and welded in a state where the surface of the foamed resin layer 1 is melted by heating. By welding in this way, it can prevent that the foamed resin layer 1 and the resin sheet 2 peel at the interface. It is also possible to laminate by sandwiching a hot melt film or the like that melts by heating between the foamed resin layer 1 and the resin sheet 2 and melting the hot melt film by heating.

  As described above, since the foamed resin layer 1 and the resin sheet 2 are laminated by a means that does not use an adhesive having a volatile component, the smell generated by the volatile component of the adhesive after the loading material 100 is attached. Will not adhere to the load. Therefore, it can also be used as a cargo storage cushion for transporting food containers and the like.

  In addition, the foamed resin layer 1 and the resin sheet 2 are preliminarily laminated, and the work of laminating and fixing the foamed resin layer 1 and the resin sheet 2 in the mounting operation in the luggage compartment can be omitted. It is possible to mount efficiently.

  Moreover, since the cushioning material 100 for the luggage compartment is produced by cutting the cushioning material in a state that is continuous in the left-right direction in the front view of FIG. 2 and the rear view of FIG. 3, it is excellent in mass productivity, It can be produced efficiently and at low cost. In addition, the dimension shape of the buffer material 100 for luggage compartments which concerns on this embodiment is an example, and it can design arbitrarily according to the place to attach.

  Next, the attachment state of the cushioning material 100 for a luggage compartment according to the present embodiment will be described. FIG. 9 is a view showing a state in which the cargo space cushioning material 100 according to the present embodiment is attached to the cargo room wall of the truck 200. FIG. 10 shows an enlarged view of a mounting portion of the cargo space cushioning material 100 in FIG. FIG. 11 is an enlarged view of an end portion of the DD cross-sectional view of the cargo-chamber cushioning material shown in FIG. 10.

  The cargo-chamber cushioning material 100 is fixed to the cargo-chamber interior wall 25 with the end portions 2a and 2b sandwiched between the two rails 22a and 22b (attachment members). The rails 22a and 22b for fixing the cargo-chamber cushioning material 100 are called lashing rails, and are provided to fix one end of a load-clamping belt for fixing the cargo in the cargo compartment. Are fixed to the cargo compartment wall 25 by rivets 23 (attachment members) attached at predetermined intervals (see FIG. 11).

  As shown in FIG. 10, the attachment member is not disposed on the surface of the foamed resin layer 1 having a role as a cushioning material, and the load can be prevented from contacting the attachment member. Further, as shown in FIG. 11, when the shock absorber 100 for the luggage compartment is attached, the end surface 100 a on the side facing the indoor direction (right direction in the figure) of the cargo compartment cushion material 100 is the rail 22 a and the rivet 23. It is formed so that it may be located in a room direction rather than the edge part by the side which goes to the room direction. Therefore, it becomes difficult for the load to come into contact with the rail 22a and the rivet 23 located on the inner wall surface 25 side of the end surface 100a of the load cushioning material, and the load can be prevented from being damaged.

  Further, since the waterproof resin sheet 2 covers the foamed resin layer 1 and is fixed to the cargo compartment wall 25 by the rails 22a and 22b, the moisture in the cargo compartment is absorbed by the cushioning material 100 for the cargo compartment and the cargo compartment wall. 25, it is difficult to enter the gap with 25. Thus, it is possible to prevent corrosion and deterioration of the cargo compartment wall 25 and the foamed resin layer 1 from being promoted by the intruded moisture. Similarly, it is possible to prevent dust or the like from entering the gap between the cargo-chamber cushioning material 100 and the cargo-chamber interior wall 25.

  In addition, since the load side surface of the foamed resin layer 1 is encapsulated by the resin sheet 2, the load does not directly contact the foamed resin layer 1, and the foamed resin layer 1 is prevented from being damaged by the contact of the load. Can do. If a part of the resin sheet 2 is damaged, it can be easily repaired by attaching a new resin sheet so as to cover the periphery of the damaged part of the resin sheet 2.

  It should be noted that the fixing of the cargo-chamber cushioning material 100 to the cargo-chamber interior wall 25 is not limited to the case where the rails 22a and 22b are used. It is also possible to pinch and fix (see FIG. 12).

  Next, a method for attaching the cargo space cushioning material 100 according to the present embodiment to the cargo compartment wall 25 will be described.

  The foamed resin layer 1 is an attachment member for fixing the cushioning material 100 for the cargo compartment to the inner wall of the cargo compartment 20 on the attachment surface 1a (see FIG. 4) which is the surface opposite to the surface on which the resin sheet 2 is laminated. What attached the double-sided tape (temporary fixing | fixed part) for temporarily fixing to the cargo-chamber interior wall 25 can be used, without using a certain rail 22a, 22b. The double-sided tape is such that the position of the cushioning material 100 for the luggage compartment is not displaced by gravity until the cargo cushioning material 100 is temporarily fixed to the cargo compartment wall 25 and then fixed (mainly fixed) by the rails 22a and 22b. Can be used that has adhesive strength. For example, as shown in FIG. 17 (a rear view corresponding to FIG. 3), the double-sided tape 3 can be attached to both ends of the mounting surface 1a of the foamed resin layer 1 in the vertical direction. In order to make the temporary fixation more stable, a double-sided tape may be attached to the entire surface of the foamed resin layer 1.

  A cover sheet that can be easily peeled off at the time of use is affixed to the adhesive surface of the double-sided tape 3, and does not adhere to other members when transporting the cushioning material for cargo compartment 100. When the cover sheet is peeled off, it can be used.

  The operator peels off the cover sheet of the double-sided tape 3 and presses the exposed adhesive part against the cargo room wall 25 and temporarily fixes the cargo-chamber cushioning material 100 by the adhesive of the double-sided tape 3 in the mounting operation in the cargo room 20. I do. Thereafter, the rail 22a is attached to the cargo compartment wall 25 with the rivets 23 in a state where both ends 2a of the resin sheet 2 are sandwiched between the rails 22a. Similarly, the rail 22b is attached (see FIGS. 9 and 10).

  In this way, by attaching the double-sided tape to the foamed resin layer 1 in advance, the rail 22a is temporarily attached to the cargo compartment wall 100 using the rivets 23 in a state where the cargo compartment cushioning material 100 is temporarily fixed to the cargo compartment wall 25. It can be fixed to the cargo compartment wall 25. As a result, when the rail 22a is attached, the operator does not need to hold the cargo space cushioning material 100 in accordance with the attachment position, so that the operator can perform the attachment operation alone. Therefore, the number of workers required for installation can be reduced, and the installation cost can be reduced. In addition, it is possible to suppress positional deviation during the main fixing.

  The temporary fixing described above is not limited to the case where the double-sided tape 3 is used. The temporary fixing has a predetermined adhesive strength that temporarily holds the cushioning material for the cargo compartment, and the adhesive strength decreases after the main fixing is completed. Any adhesive material can be used. In this case, after a certain period of time has elapsed after the attachment, by removing the attachment member used for the main fixation, the cargo space cushioning material can be easily removed, and the replacement work can be performed efficiently.

  Note that the cargo compartment wall 25 that is a member to be attached may be a surface to which an attachment member such as a lashing rail can be stably attached, and is not necessarily a perfect plane. On the other hand, in the conventional attachment method using an adhesive, it is necessary to make the attachment surface flat in order to obtain a sufficient adhesive force. For this purpose, work such as attaching a separate flat plate to the cargo compartment wall has been performed. In addition, it is necessary to sufficiently remove the dirt on the wall of the luggage compartment, which is the surface to be bonded. By using the cargo-chamber cushioning material according to the present embodiment, such work can be omitted and attachment can be performed efficiently.

  Further, the foamed resin layer 1 and the resin sheet 2 can be easily cut with a cutter or the like, and can be easily dimensioned at the work site. Moreover, since the resin sheet 2 is formed of a material that is harder to cut than the foamed resin layer 1, the resin sheet 2 is cut by pressing a sharp member against the foamed resin layer 1 to such an extent that the resin sheet 2 is not cut. It is possible to cut only the foamed resin layer 1 without any problem, and it is possible to peel off the unnecessary portion of the foamed resin layer 1 while destroying the base material in the vicinity of the interface with the resin sheet 2. In this way, the state in which the resin sheet 2 extends out of the surface of the foamed resin layer 1 is newly removed by partially removing the foamed resin layer 1 from the resin sheet 2 at the edge of the cushioning material for the luggage compartment. It is also possible to adjust the dimensions by forming them.

  Moreover, as shown in this embodiment, not only when the edge parts 2a and 2b of the resin sheet 2 are laminated | stacked so that it may extend out of the surface of the said foamed resin layer 1, it is an edge part of 4 sides. All may extend out of the surface of the foamed resin layer 1. FIG. 13 shows a front view of such a loading chamber cushioning material 110. 14 is a rear view, FIG. 15 is a left side view, and FIG. 16 is a plan view. In this case, for example, as shown in FIG. 19, it is possible to fix all the edges of the four sides of the resin sheet 12 laminated on the foamed resin layer 11 by the lashing rails 22a and 22b and the plates 28a and 28b. It can be fixed more stably.

  Moreover, as shown in this embodiment, it is not restricted to the case where all the edges which the resin sheet 2 extends are fixed to a to-be-attached member. For example, after temporarily fixing with the double-sided tape 3, it is also possible to fix only the one side edge 2a with the rail 22a. Moreover, as shown in FIG. 18, the edge part 2b which is not fixed with a rail is arrange | positioned so that the upper part of the member 101 arrange | positioned adjacently, such as another buffer material, may be covered, and the buffer material for luggage compartments It is possible to prevent water, dust, and the like from entering the gap between the member 100 adjacent to 100.

  Further, as shown in FIGS. 9 and 19, the same applies to the ceiling 26 of the luggage compartment and the wall surface 27 that divides the cargo compartment in the depth direction, not only when the cargo cushions 100 and 110 are attached to the sidewall of the luggage compartment. It is possible to attach to.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims.
