[First Embodiment]
Hereinafter, the luggage board 10 according to the first embodiment of the first embodiment will be described with reference to FIGS. 1 to 5. The luggage compartment of the vehicle 90 shown in FIG. 1 includes a lower luggage compartment 92 below the upper luggage compartment 91, which is a so-called trunk chamber. Further, as shown in FIG. 2, substantially the entire bottom surface 91A of the upper luggage compartment 91 excluding the outer edge portion has an opening 92K of the lower luggage compartment 92. Then, the luggage board 10 of the first embodiment is overlapped with the entire bottom surface 91A of the upper luggage compartment 91, for example, and closes the opening 92K of the lower luggage compartment 92. Further, the lower luggage compartment 92 is divided into a plurality of accommodation spaces by a support wall 93 perpendicular to the bottom surface thereof. The support wall 93 extends to the same height as the bottom surface 91A of the upper luggage compartment 91, and supports the central portion of the luggage board 10 from below.

Here, in general, a board that closes the opening of the luggage compartment of a vehicle is classified into a "luggage board" and a "deck board", and the outer edge portion is supported from below and a part other than the outer edge portion is provided in the luggage compartment. What is supported by the support wall is called a "luggage board". On the other hand, a "deck board" is a state in which only the outer edge portion is supported from below and the entire portion other than the outer edge portion is floated without being supported from below. Both the outer edges of the "luggage board" and the "deck board" may be supported by the entire outer edge or only part of the outer edge (eg, a pair of opposite edges of the luggage compartment opening). There may be. Since the "luggage board" has more parts supported from below than the "deck board", it does not need to be as strong (rigid) as the deck board, and as a result, it is possible to reduce the weight and thickness.

The luggage board 10 of the first embodiment has a flat plate shape, the outer edge portion is supported by the bottom surface 91A of the upper luggage compartment 91, and the central portion is supported by the upper portion of the support wall 93.

For example, the covering sheet 20 has a flat shape slightly larger than that of the board main body 11 to cover the entire upper surface of the board main body 11, and the outer edge portion is folded back to form the entire side surface of the board main body 11 and the outer edge portion of the lower surface. Covering. The covering sheet 20 may cover the entire outer surface of the luggage board 10.

Examples of the non-woven fabric constituting the covering sheet 20 include a spunlace non-woven fabric, a spunbonded non-woven fabric, and a needle punched non-woven fabric. Examples of the fibers of the non-woven fabric include natural fibers such as wool and cotton, synthetic fibers such as polyester fibers and polypropylene fibers, and examples of the amount of graining include 10 to 300 g / m ² . Further, the covering sheet 20 does not have to be a non-woven fabric as long as it has breathability. For example, a woven fabric made of synthetic fiber or metal, a mesh material made of thermoplastic resin or metal, or a plurality of through holes. It may be a thermoplastic resin sheet or a metal sheet in which the material is perforated. In the case of a sheet having through holes, it is preferable that the diameter thereof is smaller than the diameter of the deodorizing material 40 described later. Further, the covering sheet 20 may be composed of a single layer, or may be combined with different materials to form a plurality of layers. Here, the air permeability of the covering sheet 20 is preferably 10 to ^{200 cm 3} / cm ² · s in the JIS L1096: 2010 A method (Frazier type method). If the air permeability of the covering sheet 20 ^{is higher than 200 cm 3} / cm ² · s, the adhesive described later may easily seep out from the covering sheet 20.

FIG. 3 shows an example of the board body 11 according to the first embodiment. The board body 11 is configured by stacking the back side plate 13 and the front side plate 17 on an uneven plate 12 having a plurality of small chambers 31N that open on the upper surface. Specifically, as shown in FIG. 4A, the concave-convex plate 12 is made of, for example, a thermoplastic resin, and projects downward from the upper surface having a plurality of bulging portions 31 formed by vacuum forming. The inside of these bulging portions 31 is a small chamber 31N in preparation for the above-mentioned state.

Further, each of the bulging portions 31 has a tapered shape that narrows toward the bottom, and as shown in FIG. 3, the lower end surfaces of all the bulging portions 31 are flush with each other and horizontal. That is, the uneven plate 12 is formed so that the small chamber 31N inside the bulging portion 31 has a bottom surface. Here, the uneven plate 12 used in the first embodiment is made of a non-breathable thermoplastic resin, but may have a breathable structure like the front side plate 17 described later.

The back plate 13 is made of, for example, a thermoplastic resin, and is fixed to the lower surface of the concave-convex plate 12 (that is, the lower end surfaces of the plurality of bulging portions 31) by vibration welding or heat welding. The thickness of the back plate 13 is substantially the same as that of the uneven plate 12. Further, it is preferable that the thermoplastic resin constituting the back side plate 13 and the concavo-convex plate 12 has the same composition or the same main component of the composition from the viewpoint of fixing the two. Here, the uneven plate 12 and the back plate 13 may be fixed by an adhesive. Further, both may be fixed over the entire surface or may be partially fixed.

The front plate 17 is made of a rigid and breathable material. Specific examples thereof include woven fabrics made of synthetic fibers and metals, mesh materials made of thermoplastic resins and metals, and thermoplastic resin sheets and metal sheets having a plurality of through holes. From the viewpoint of weight reduction and ease of molding, the front plate 17 is preferably made of a thermoplastic resin having through holes. If the front side plate 17 and the uneven plate 12 use a thermoplastic resin having the same composition or a common main component of the composition, both can be fixed not only by adhesive but also by vibration welding or heat welding. At that time, both may be fixed over the entire surface or may be partially fixed.

The thickness of the portion of the uneven plate 12 that does not have the bulging portion 31 is preferably 0.1 to 3 mm, more preferably 0.15 to 1 mm. The total thickness of the concavo-convex plate 12 (that is, the thickness from the upper surface of the concavo-convex plate 12 to the lower end surface of the bulging portion 31) is preferably 2 to 10 mm, more preferably 3 to 7 mm. The thickness of the back plate 13 and the front plate 17 is preferably 0.1 to 3 mm, more preferably 0.15 to 1 mm. Examples of the thermoplastic resin constituting the uneven plate 12, the back plate 13 and the front plate 17 include polyethylene resin, polypropylene resin, polyethylene terephthalate resin, nylon resin and the like. Further, the uneven plate 12, the back plate 13 and the front plate 17 may be made of a thermosetting resin, or may be made of metal or paper. Examples of the thermosetting resin include phenol resin, epoxy resin, melamine resin, urethane resin and the like, and examples of the metal include aluminum, stainless steel and the like. Examples of paper include kraft paper, general paper made of plant fibers such as pulp, paper made of synthetic fibers such as polyester, rayon, and polyvinyl alcohol, and paper made of inorganic fibers such as glass paper and graphite paper. Can be mentioned. The concave-convex plate 12, the back plate 13, and the front plate 17 are preferably made of a thermoplastic resin from the viewpoint of weight reduction and ease of molding.

The deodorizing material 40 is housed in each of the plurality of small rooms 31N of the uneven plate 12. The deodorant 40 is, for example, activated carbon granules, and each of the small chambers 31N contains a plurality of deodorant 40 granules substantially fully.

As a raw material for activated carbon constituting the deodorizing material 40, oga scraps, charcoal, coconut shells, resins and the like are generally used, but shells such as oyster shells may be used for effective use of waste. Further, the deodorizing material 40 is not limited to activated carbon as long as it is a porous body having pores, and for example, activated clay, silica gel, activated alumina, zeolite or the like can be used. Further, the deodorizing material 40 made of these porous bodies may be composed of one type or a plurality of types. Here, the specific surface area of the porous body constituting the deodorant 40 ^{is preferably 500 m 2} / g or more, and more preferably 1000 m ² / g or more. The upper limit of the specific surface area of the porous body is not particularly limited, and examples ^{thereof include 5000 m 2} / g.

The form of the deodorizing material 40 does not have to be the above-mentioned granules, for example, it may be powdery, rod-shaped, fibrous, or plate-shaped, and one deodorizing material 40 is housed in each small room 31N. It may be configured as a new type. However, from the viewpoint of workability of accommodating the deodorizing material 40 in the bulging portion 31, the deodorizing material 40 is preferably granular, and when a plurality of deodorizing materials 40 are accommodated in each small room 31N, the specific surface area of the deodorizing material is high. It is more preferable because the deodorizing effect is improved. The particle size of the deodorizing material 40 is preferably 0.3 to 3 mm, more preferably 0.5 to 2 mm.

The concave-convex plate 12 and the front side plate 17 constituting the board main body 11, the board main body 11 and the covering sheet 20 are fixed by the adhesive 19. Here, the concavo-convex plate 12 made of a thermoplastic resin and the back side plate 13 made of a thermoplastic resin are preliminarily fixed by vibration welding or heat welding by superimposing the back side plate 13 on the lower surface of the concavo-convex plate 12.

After accommodating the deodorizing material 40 in the plurality of bulging portions 31 (small room 31N) in the concave-convex plate 12 to which the back side plate 13 is fixed, deodorizing is performed by covering the openings 31K of the plurality of bulging portions 31 with the front side plate 17. The material 40 is held in each small room 31N. At that time, the adhesive 19 is arranged between the concavo-convex plate 12 and the front side plate 17 in a state of being breathable, and both are fixed.
After that, the board body 11 in which the deodorizing material 40 is housed in the small room 31N and the covering sheet 20 are fixed in a state where the adhesive 19 has breathability. In the first embodiment, each of the small rooms 31N accommodates a plurality of deodorizing materials 40. Further, in the adhesion between the uneven plate 12 and the front side plate 17, a part of the adhesive 19 has a mesh shape covering the opening 31K of the small room 31N, and when the front side plate 17 is attached to the uneven plate 12. It adheres to a part of the deodorizing material 40 in the small room 31N. As a result, it is possible to regulate the jumping and movement of the deodorizing material 40 in the small room 31N. When the concave-convex plate 12, the back plate 13, the front plate 17, and the coating sheet 20 constituting the board body 11 are all made of thermoplastic resin, heat welding and super-welding can be performed without using the adhesive 19. It can be fixed by ultrasonic welding or the like.

Examples of the adhesive 19 include known adhesives such as water-based or solvent-based dry-solidified adhesives made of synthetic resin or rubber, chemically reactive adhesives made of epoxy or polyurethane, hot-melt adhesives such as hot melt, and the like. The agent can be used. Further, it is preferable that the adhesive 19 is used by spraying or is previously molded into a web shape (sheet shape having a mesh structure) and used because the adhesive 19 has breathability.

The structure of the luggage board 10 of the first embodiment has been described above. Next, an example of a method for manufacturing the luggage board 10 will be described.

In the method for manufacturing the luggage board 10 of the first embodiment, a plate in which the concave-convex plate 12 and the back plate 13 are integrated in advance and a front plate 17 in which, for example, a web-shaped adhesive 19 is integrated are prepared. It is cut into a shape substantially the same as the bottom surface 91A of the first luggage compartment 91 shown in FIG. The front side plate 17 having breathability is fixed to the uneven plate 12 in a state where the adhesive 19 has breathability, and the board body 11 is manufactured. Further, a covering sheet 20 in which the adhesive 19 is integrated is prepared in advance, and the coating sheet 20 is cut into a shape one size larger than the uneven plate 12 or the like cut as described above, and has a plurality of notches on the outer edge portion. .. Here, the concave-convex plate 12 and the back plate 13 are both thermoplastic resins, and are fixed by vibration welding or heat welding.

As a pre-process for producing the board main body 11, first, the deodorizing material 40 is filled into a plurality of bulging portions 31 of the uneven plate 12 in which the back side plate 13 is fixed to the lower surface. For that purpose, for example, the concave-convex plate 12 is made horizontal and vibration is applied in the horizontal direction. Then, the granules of the deodorizing material 40 are supplied onto the uneven plate 12, and the entire upper surface is covered. Next, the vibration to the concavo-convex plate 12 is stopped, and for example, the spatula is slidably moved on the upper surface of the concavo-convex plate 12, and the excess deodorizing material 40 on the concavo-convex plate 12 is removed.

Then, the front side plate 17 is superposed on the upper surface of the concavo-convex plate 12 in which the deodorizing material 40 is housed, and is fixed by the adhesive 19 to produce the board body 11. After that, the covering sheet 20 which is one size larger than the board main body 11 is overlapped and fixed to the board main body 11. After that, the extra length of the covering sheet 20 is folded back and fixed to the outer edge of the back plate 13 of the board body 11, thereby completing the luggage board 10. Here, the concavo-convex plate 12 and the breathable front plate 17 are fixed by the adhesive 19 in a breathable state. At that time, a part of the adhesive 19 enters the small room 31N and is fixed to a part of the deodorizing material 40. Further, since the board body 11 and the covering sheet 20 are fixed by the adhesive 19 in a breathable state, the air (odor) outside the luggage board 10 can come into contact with the deodorizing material 40. , The luggage board 10 itself has a deodorizing effect.

The manufacturing method of the luggage board 10 is not limited to this, and can be changed as appropriate. For example, the uneven plate 12 and the back plate 13 may not be fixed to each other. Even if the concavo-convex plate 12 and the back side plate 13 are not fixed, the luggage board 10 can be formed by folding back the outer edge portion of the covering sheet 20 and fixing it to the back side plate 13. However, in order to produce the luggage board 10 having higher rigidity, it is preferable that the uneven plate 12 and the back side plate 13 are fixed to each other. Further, the concave-convex plate 12 and the front side plate 17 do not have to be fixed to each other. As described above, the front side plate 17 is covered with the covering sheet 20, and the outer edge portion thereof is folded back and fixed to the back side plate 13 to form the luggage board 10. However, in order to produce the luggage board 10 having higher rigidity, it is preferable that the uneven plate 12 and the front side plate 17 are fixed to each other. Further, the front plate 17 may be omitted. However, in order to produce the luggage board 10 having higher rigidity, it is preferable that the board main body 11 has the back side plate 13 and the front side plate 17 on the uneven plate 12.

Further, the adhesive 19 does not have to be integrated with the front plate 17 and the covering sheet 20 in advance. In this case, after the deodorizing material 40 is housed in the small room 31N of the concavo-convex plate 12, the adhesive 19 is sprayed from the upper surface of the concavo-convex plate 12 (the small room 31N side containing the deodorizing material 40) to bond the front side plates 17. The adhesive 19 may be sprayed from the outside of the board body 11 (back side plate 13 and front side plate 17) to bond and fix the covering sheet 20. However, from the viewpoint of workability, it is preferable that the adhesive 19 is integrated with the front plate 17 and the covering sheet 20 in advance. Further, the adhesive 19 does not have to enter the small chambers 31N, and by covering the openings 31K of the plurality of small chambers 31N in a mesh pattern, as a result, it becomes a part of the deodorant 40 in the vicinity of the openings 31K. It may be fixed.

This is the end of the manufacturing method of the luggage board 10. Next, the action and effect of the luggage board 10 will be described. The luggage board 10 closes the opening 92K between the first luggage compartment 91 and the second luggage compartment 92 of the vehicle 90. The luggage board 10 has a deodorizing effect because the surface on the first luggage compartment 91 side, that is, the surface on the side accommodating the deodorizing material 40 is covered with the front side plate 17 and the covering sheet 20 having breathability. Further, since the luggage board 10 is provided with the deodorizing function, it does not interfere with passengers and luggage and is excellent in stability. Further, if the structure is such that the deodorizing material 40 is housed in the entire upper surface of the luggage board 10, the contact area with air can be made wider than that of the conventional deodorizing product, so that a higher deodorizing effect than the conventional one can be obtained. can.

For example, when a load that emits an odor is accommodated on the second luggage compartment 92 side, the luggage board 10 is turned upside down from the normal state so that the opening 31K of the small chamber 31N faces downward. You may use it.

Further, it is expected that the deodorizing material 40 is a granular porous body and has voids between the particles to impart a sound absorbing effect to the luggage board 10.

Further, the back side plate 13, the front side plate 17, and the concavo-convex plate 12 are fixed with a space in between to form the board main body 11, so that the structure is such that the face materials having rigidity on both sides are unevenly distributed, which is lightweight. However, high bending strength is obtained, and the usability of the luggage board 10 is improved.

However, when the concavo-convex plate 12 itself has high bending strength, as shown in FIG. 5, the board main body 11 may be configured not to include the back side plate 13 and the front side plate 17. In this case, since the step of fixing the concave-convex plate 12 to the back plate 13 and the front plate 17 becomes unnecessary, the production of the luggage board 10 is facilitated.

All of the modifications of the first embodiment described above can also be applied to the deck boards 10A to 10C and other embodiments of the second to fourth embodiments described below.

[Second Embodiment]
Hereinafter, with reference to FIG. 6, the luggage board 10A of the second embodiment of the present disclosure will be described only with respect to a configuration different from that of the luggage board 10 of the first embodiment.

In the figure, the internal structure and the outer edge of the luggage board 10A are enlarged and shown. The board body 11A of the luggage board 10A is formed with a space 31R surrounded by the outside of the bulging portion 31 of the concave-convex plate 12 and the back plate 13A. Further, the deodorizing material 40 is housed in the space portion 31R. Since the back plate 13A is made of, for example, a mesh material made of a thermoplastic resin, it has breathability. The concave-convex plate 12 made of a thermoplastic resin and the back plate 13A made of a thermoplastic resin and having air permeability are fixed by vibration welding or heat welding.

Further, the entire side surface of the board body 11A is covered with the side surface closing member 16. The side closing member 16 has a U-shaped cross section made of, for example, a thermoplastic resin, and sandwiches the outer peripheral portion of the board body 11 inside the side closing member 16. The side closing member 16 prevents the deodorizing material 40 from falling from the space 31R. Here, the side closing member 16 may have air permeability.

The manufacturing method of the luggage board 10A of the second embodiment is as follows. First, the deodorizing material 40 is housed in the bulging portion 31 (small room 31N) of the concave-convex plate 12 to which the back side plate 13 having air permeability is fixed in advance. After that, the opening 31K of the bulging portion 31 is covered with the front side plate 17 having breathability, and the board body 11A in which the deodorizing material 40 is held is produced. Next, the side closing member 16 is fixed to three of the four side surfaces of the board body 11A, and the remaining one surface is opened laterally. After that, the board body 11A is tilted so that the opening surface to which the side closing member 16 is not fixed is on the upper side, and the space portion 31R formed by the outer side of the bulging portion 31 of the concave-convex plate 12 and the back side plate 13A is formed. The deodorant 40 is filled. At that time, the filling rate of the deodorizing material 40 in the space 31R can be increased by vibrating the board body 11A from time to time. After filling the deodorizing material 40, the opening surface is fixed by the side closing member 16, so that the deodorizing material 40 can be held by the board body 11A. Then, the board body 11A is covered with the covering sheet 20 and fixed to complete the luggage board 10A. In the second embodiment, only a part of the back plate is fixed to the covering sheet 20, but the entire surface may be fixed. In the second embodiment described above, the deodorizing material 40 has a diameter of the particle size smaller than that of the bulging portion 31, and is movable in the space portion 31R.

Further, the luggage board 10A may be manufactured as follows. First, the deodorizing material 40 is housed in the bulging portion 31 of the concave-convex plate 12, and the opening 31K of the bulging portion 31 is covered with the front side plate 17 having breathability. Next, for example, the side closing member 16 having an L-shaped cross section is fixed to the outer edge of the front plate 17 by heat fusion, for example.
