  The present invention relates to a foldable board and an automobile provided with the foldable board.

  Conventionally, for this type of foldable board, for example, a foldable plate-like body described in Patent Document 1 has been proposed. This foldable plate-like body is configured by connecting both plate-like bodies in a foldable manner via a hinge portion.

  Here, the hinge portion is provided so as to face both the connecting portions between the two connecting portions projecting so as to face each other from the opposing end walls of the two plate-like bodies. The two bent portions having a substantially V-shaped cross section and a flat portion interposed between the two bent portions are configured.

  Thereby, the foldable plate-like body is configured such that one of the two plate-like bodies is folded toward the other plate-like body with reference to the hinge portion.

Japanese Patent Laid-Open No. 10-71652

  By the way, in the case where the above-described foldable plate-like body is used as, for example, a lid of a storage box also used as a floor member provided on the rear floor of a vehicle interior floor of a one-box type automobile, the foldable plate-like body is stored. It will be arrange | positioned at the said opening part so that the opening part of a warehouse may be obstruct | occluded.

  Here, the foldable plate-like body is usually placed at the outer peripheral portion of the plate-like body on the inner peripheral portion of the opening portion of the storage case, thereby being disposed at the opening portion of the storage case. For this reason, each opposing edge part of both plate-shaped bodies will be in the floating state in a storage, without being supported in parts other than the both ends, and lacks in mechanical strength.

  Therefore, in such a state, for example, when a load is applied to the center portion of each opposed end portion of both plate-like bodies from the upper side, the both plate-like bodies are stored in the storage at the center portion of each opposed end portion. Deflection toward the inside of the. As a result, there arises a problem that the foldable plate-shaped body is difficult to serve as a floor member lid.

  Therefore, in order to deal with the above, the present invention connects at least two board members that are foldable to each other by hinges at the respective opposite end portions. The present invention aims to provide a foldable board with high mechanical strength and an automobile equipped with this foldable board.

In solving the above-mentioned problem, the folding board according to the present invention, according to the description of claim 1,
At least two board members (60a, 60b) that are sequentially arranged in a direction along the surface and made of a predetermined board material;
Hinge means (67) is provided for each adjacent board member adjacent to each other among these at least two board members so as to connect the both adjacent board members so that they can be folded together.

  Here, one board member of the two adjacent board members includes a board main body (61) and an upper protruding plate portion protruding from the upper portion of the board main body end portion (61a) toward the other board member. (62) and a plurality of protrusions projecting toward the other board member so as to extend from the lower portion of the end portion of the board body to the other board member side rather than the upper protruding plate portion. And lower protruding plate portions (63a, 63b).

  The other board member can be joined to the upper protruding plate portion of the one board member from the upper portion of the board body (64) and the end portion of the board body facing the one board member. The upper protruding plate portion (65) protruding toward the upper protruding plate portion and the plurality of the one board members from the lower portion of the end portions of the board body facing the one board member. Each lower protruding plate portion (66) protrudes so as to be insertable between each adjacent lower protruding end portion of the lower protruding end portions.

  In addition, the hinge means is provided from the surface side to each opposing end portion of the upper projecting plate portions, and connects the adjacent board members so that they can be folded together.

  Thus, if the foldable board is detachably fitted into an opening of a storage box that is fitted into an opening formed in a floor of a kitchen of a general house or an automobile, for example, the foldable board Serves as a lid for the storage while also serving as a floor member of the floor.

  In such a state, when taking out the contents in the storage or storing other things in the storage, one board member of the board is placed on the other board member via the hinge means. When folded, the board opens the opening of the opening of the storage with the other board member. As a result, the stored items in the storage can be taken out, or other items can be stored in the storage.

  After that, when the opening portion of the opening of the storage is closed by the one board member via the hinge means, the board again serves as a lid for the storage while also using the floor member of the floor. At this time, the other board member is fitted between each of the adjacent lower protruding plate portions among the plurality of one board members at each lower protruding plate portion.

  In such a state, when a person gets on the board or a luggage is placed on the board, the load of the person or the luggage acts on the board from the upper side toward the inside of the storage. . Here, if the board is only supported at the outer periphery thereof from below by the inner surface of the opening of the storage, the board is maintained in a floating state at a portion other than the outer periphery. It will be.

  For this reason, if the load mentioned above acts on parts other than the outer peripheral part of a board, a board will be going to curve to the inner side of a storage with the action point of the load being the center. At this time, the closer the action point of the load is to the center of the board, the more the board tends to bend toward the inside of the storage.

  Here, even if the load acts on the portion of the board that is most likely to be bent, on the opposite end portion of one board member, the load is applied to the upper protruding plate portion of one board member and directly below it. It is received by each lower protruding plate portion of the other board member in contact with the upper protruding plate portion. For this reason, one board member can maintain an original shape favorably irrespective of the effect | action of the said load. Further, even if a load acts on the opposite end portion of the other board member, the load is applied to the upper protruding plate portion of the other board member and one board member that comes into contact with the upper protruding plate portion immediately below the upper protruding plate portion. Are received by each lower projecting plate portion. For this reason, the other board member can maintain the original shape satisfactorily despite the action of the load.

  As a result, no matter which part of the board 60 the load acts on from above, the board 60 plays a role as a lid that also serves as a floor member for the storage without being affected by the load. obtain.

Moreover, according to the description of claim 2, the present invention provides the folding board according to claim 1,

The skin member, for each of the two adjacent boards of the at least two board members, constitutes a hinge means at a corresponding portion with respect to each opposing end portion of the upper projecting plate portions of the two adjacent boards. To do.

  According to this, an outer skin member plays the role as a hinge means in the said corresponding | compatible part. As a result, the board serves as a lid of the storage, using the corresponding portion of the skin member as a hinge means without adopting a hinge means separately. A working effect can be achieved.

According to the description of claim 3, the present invention provides the folding board according to claim 1,
For each of the two adjacent boards, the hinge means is a plurality of hinge members provided at intervals in a direction along the boundary across the opposing end portions of the upper projecting plate portions.

  As described above, even if a plurality of hinge members are provided in place of the hinge means according to the first aspect, the same effects as those of the first aspect can be achieved.

According to a fourth aspect of the present invention, in the foldable board according to any one of the first to third aspects,
The predetermined board material is formed by foaming by laminating a plate-shaped honeycomb body between both glass fiber mats infiltrated with a foamable thermosetting resin and heating and pressing. .

Hereinafter, each embodiment of the present invention will be described with reference to the drawings.
(First embodiment)
FIG. 1 shows a first embodiment in which the present invention is applied to a hatchback type automobile. This automobile is provided with a luggage compartment 10, and the luggage compartment 10 is provided in the vehicle body of the automobile. The left and right rear walls 20 of the vehicle body (only one inner wall rear 20 is shown in FIG. 1), Surrounded by both side seats 30 and a back door (not shown) provided at the rear part of the vehicle body, it is formed between an upper rear part (not shown) of the vehicle body and a rear part of the floor 40 of the vehicle body. Yes. The left and right side seats 30 are arranged on the left and right on the front part of the floor 40 of the body of the automobile.

  In addition, the automobile includes a storage 50, and the storage 50 is fitted in an opening formed in the rear portion of the floor 40. Here, the storage 50 extends from the storage body 51 having a U-shaped cross section and an opening of the storage body 51 (hereinafter, also referred to as an opening of the storage 50) in an L-shaped section. It is configured with a square annular flange 52 that comes out. As a result, the storage 50 is inserted into the opening on the rear part of the floor 40 from the upper side to the lower side in the storage body 51, and on the opening on the rear part of the floor 40 by the flange 52. By being seated, it is fitted as described above. In the storage 50, spare tires and other items are stored.

  Further, as shown in FIG. 1, the automobile includes a foldable board 60, and this board 60 is in an L-shaped opening 51 a (see FIG. 7) in the transverse section of the storage body 51 of the storage 50. Is detachably fitted. Here, the board 60 is fitted as described above by seating on the annular bottom surface of the L-shaped opening 51a of the transverse section of the storage body 51 at the bottom of the outer periphery thereof. Note that the front and rear side board members 60a and 60b are configured to close the opening of the storage 50 half by half across the front and rear.

  As shown in FIG. 2 in an enlarged manner, the board 60 includes front and rear side board members 60a and 60b and a skin member 60c. The front board member 60a is as shown in FIG. 3 or FIG. The member body 61, the upper protruding plate portion 62, and the left and right lower protruding plate portions 63a and 63b are integrally formed of a board material M (see FIG. 6).

  Here, the upper protruding plate portion 62 is formed so as to protrude rearward from the upper portion of the rear end portion 61 a (see FIGS. 2 and 4) of the member main body 61. The left and right lower protruding plate portions 63a and 63b are spaced apart from each other by a predetermined distance in the left and right direction so as to extend rearward from the lower portion of the rear end portion 61a of the member body 61 along the upper protruding plate portion 62. And projecting backward (see FIG. 4).

  As shown in FIG. 6, the board material M includes both glass fiber mats M1 and M2, and a honeycomb body M3 laminated between the glass fiber mats M1 and M2. In the first embodiment, both glass fiber mats M1 and M2 are formed by consolidating glass fibers cut to a length within 50 to 100 (mm) with a binder and molding them into sheets. ing. Both glass fiber mats M1 and M2 formed in this way are lightweight and have a characteristic of being strong against stress in a direction perpendicular to the thickness direction of the honeycomb body M3.

  The honeycomb body M3 is made of a plate-like paper honeycomb body having a predetermined thickness. The honeycomb body M3 is formed by sequentially bonding a plurality of paper pieces to each adjacent two paper pieces at predetermined intervals. Thus, it is formed by expanding in the thickness direction of the paper piece so as to form a large number of hexagonal apertures. The honeycomb body M3 formed in this manner is lightweight and has a characteristic that it is strong against stress acting in the thickness direction.

  Thus, the board material M is manufactured as follows using the two glass fiber mats M1 and M2 and the honeycomb body M3 formed as described above.

  First, a roll-shaped glass fiber mat material (made of the same forming material as the glass fiber mats M1 and M2) for forming both the glass fiber mats M1 and M2 by cutting is prepared. Then, while the roll-shaped glass fiber mat material prepared in this way is sequentially pulled out horizontally on the conveyor, a certain amount of foamable thermosetting property is placed on the roll-shaped glass fiber mat material that is sequentially pulled out in this way. Spread the resin evenly in sequence.

  Thereafter, the roll-shaped glass fiber mat material to which the foamable thermosetting resin is sequentially sprayed in this way is heated at a heating temperature in the range of the melting temperature of the foamable thermosetting resin and the curing start temperature. To do. Thereby, the thermosetting resin sequentially sprinkled on the roll-shaped glass fiber mat material is adhered to the glass fiber mat by melting thereof.

  Next, the foamable thermosetting resin is cooled and solidified by sandwiching the glass fiber mat material to which the thermosetting resin has been adhered by melting in this way by sandwiching it with a pair of rollers and feeding it. Thereafter, the glass fiber mat material obtained by cooling and solidifying the thermosetting resin in this manner is cut into predetermined lengths corresponding to the glass fiber mats M1 and M2, respectively, to form the glass fiber mats M1 and M2.

  Thereafter, the above-described honeycomb body M3 is laminated so as to be sandwiched between the two glass fiber mats M1 and M2. At this time, the two glass fiber mats M1 and M2 are laminated so as to face each surface of the honeycomb body M3 on the surface to which each thermosetting resin is attached.

  And the laminated body laminated | stacked in this way is pressurized and heated with a press, and it shape | molds. In this molding process, as described above, the foamable thermosetting resin adhered to both the glass fiber mats M1 and M2 is foamed, and between the glass fiber mats M1 and M2 and in each hexagonal opening of the honeycomb body M3. It hardens while entering. In this way, the board material M is manufactured.

  In the board material M manufactured in this way, both the glass fiber mats M1 and M2 are lightweight and strong against stress in the direction perpendicular to the thickness direction as described above, and the honeycomb body M3. However, as described above, it has the characteristics of being lightweight and strong against stress acting in the thickness direction. Accordingly, the properties of both the glass fiber mats M1 and M2 and the honeycomb body M3 can be combined to provide a board material M that is lightweight and has high rigidity.

  Note that the above-described foamable thermosetting resin does not completely enter into each aperture portion of the honeycomb body M3 due to the foaming because of resistance due to air pressure in each aperture portion of the honeycomb body M3. Therefore, an air part remains in each aperture of the honeycomb body M3. As a result, the board material M has high sound absorption and heat insulation.

  The board material M manufactured as described above is formed as the front board member 60a by being formed according to the outer shape of the front board member 60a.

  As shown in FIG. 2, FIG. 3, or FIG. 5, the rear board member 60 b has a board material M so as to integrally include a board body 64, an upper protruding plate portion 65, and a lower protruding plate portion 66. (See FIG. 6).

  Here, the upper protruding plate portion 65 protrudes forward from the upper half portion of the front end portion 64a of the board main body 64 so as to correspond to the upper half portion of the rear end portion 61a of the board main body 61 of the front board member 60a. However, the protruding length of the upper protruding plate portion 65 is equal to the protruding length of the left and right protruding plate portions 62 and 63 of the front board member 60a. Further, the lower protruding plate portion 66 extends from the lower half portion of the front end portion 64a of the board main body 64 in the left-right central portion so as to correspond to the U-shaped recess 61b of the board main body 61 of the front board member 60a. It protrudes forward from the portion 65 (see FIG. 5).

  However, the protruding length of the lower protruding plate portion 66 from the front end portion of the upper protruding plate portion 65 matches the depth length from the rear end portion of the board body 61 of the U-shaped recess 61b of the front board member 60a. To do. In FIG. 5, reference numeral 64 b denotes a gripping recess. The gripping recess 64 b is formed from the front surface side of the board main body 64 at the center of the rear end in the left-right direction of the board main body 64. As a result, the gripping recess 64b forms a gripping portion together with the central portion of the board body 64 in the left-right direction rear end.

  The skin member 60c is formed of a non-woven fabric, and the skin member 60c is applied to the surface of the board body 61 of the front board member 60a and the upper protruding plate portion 65 of the rear board member 60b and the surfaces of the board body 64. It is worn.

  Thereby, the skin member 60c is a board part 60a in the corresponding | compatible part with respect to the boundary part of the rear-end part 61a of the board main body 61 of the front side board member 60a, and the front-end part of the upper side protrusion board part 65 of the rear side board member 60b. , 60b are connected to each other as a hinge portion (hereinafter also referred to as hinge portion 67) (see FIG. 1, FIG. 2, or FIG. 3).

  In the first embodiment, as the above-described nonwoven fabric, a needle punch nonwoven fabric having sufficient strength so that the hinge function for hinge-connecting the front and rear side board members 60a, 60b can be satisfactorily exhibited, or this needle punch A non-woven fabric obtained by applying a latex to the non-woven fabric from its back surface is employed. In the skin member 60c, an opening H is formed corresponding to the holding recess 64b as shown in FIG.

  In the first embodiment configured as described above, the foldable board 60 is detachably fitted into the L-shaped opening 51a in the transverse section of the storage body 51 of the storage 50 as shown in FIG. If so, the board 60 is seated on the annular bottom surface of the transverse section L-shaped opening 51a of the storage body 51 at the bottom of the outer periphery as described above. Thereby, the board 60 serves as a lid for the storage 50 while also serving as a floor member at the rear of the floor 40 in the automobile.

  In such a state, when taking out the stored items in the storage 50, for example, spare tires, or storing other items in the storage 50, the occupant is at the rear side of the vehicle body of the vehicle. Then, the back door is opened, the grip portion of the rear board member 60b of the board 60 is gripped and lifted upward. Here, as described above, since the rear board member 60b is formed of the lightweight board material M, it is lightweight. Accordingly, the passenger can easily lift the rear board 60b as described above.

  Accordingly, as shown in FIG. 7, the rear board member 60b is shown in FIG. 1 through the hinge portion 67 of the skin member 60c with reference to the rear end portion 61a of the board body 61 of the front board member 60a. As shown in FIG. 3, it turns clockwise and is folded on the front board member 60a. Thereby, the board 60 opens the rear half part of the opening part of the storage 50 in the rear board member 60b. As a result, the spare tire in the storage 50 can be taken out, or other items can be stored in the storage 50.

  Thereafter, when the occupant grips the grip portion of the rear board member 60b and lifts it upward, the rear board member 60b is moved to the rear end of the board body 61 of the front board member 60a as shown in FIG. Using the portion 61a as a reference, it rotates clockwise in FIG. 7 via the hinge portion 67 of the skin member 60c, and closes the rear half of the opening of the storage 50. Thereby, the board member 60 plays the role of a lid for the storage 50 while also serving as a floor member at the rear of the floor 40 in the automobile. This means that the board 60 plays a role as a lid of the storage 50 while utilizing a part of the skin member 60c as the hinge portion 67 without separately adopting a hinge element.

  Here, since the skin member 60c is formed of the nonwoven fabric, the rear board member 60b can be smoothly folded with respect to the front board member 60a. Further, as described above, the non-woven fabric is formed of a needle punched non-woven fabric having sufficient strength, or a non-woven fabric obtained by applying latex to the needle punched non-woven fabric from its back surface. Thus, the hinge function can be satisfactorily exhibited over a long period without causing damage or the like. Moreover, since the skin member 60c is formed with the said nonwoven fabric, an external appearance is not impaired.

  Further, in the state where the board member 60 closes the opening of the storage 50 and serves as the lid of the storage 50 while serving as the floor member at the rear of the floor 40 as described above, for example, an occupant When the vehicle rides on the board 60 or the baggage is placed on the board 60, the load of the passenger or the baggage acts on the board 60 from the upper side toward the inside of the storage 50.

  Here, as described above, the board 60 is detachably fitted into the L-shaped opening 51a in the cross section of the storage body 51 of the storage 50, and at the bottom of the outer periphery thereof, the board 60 described above. It sits on the annular bottom surface of the L-shaped opening 51a. In other words, the board 60 is supported from below at the outer periphery by the annular bottom surface of the L-shaped opening 51a of the transverse section of the storage body 51. It faces the inside of the storage 50 and is maintained in a floating state.

  For this reason, if the load mentioned above acts on parts other than the outer peripheral part of the board 60, the board 60 tends to curve to the inner side of the storage 50 centering on the action point of the load. In the first embodiment, since the board 60 is formed of the board material M having high rigidity as described above, the bending degree of the board 60 is suppressed by the board material M, but the point of action of the load is the board. The closer to the center of 60, the greater the degree of curvature of the board 60 at the center of the board 60.

  For example, the load is the load W1, as indicated by the arrow F1 in FIG. 8 (a), with respect to the central portion in the left-right direction of the rear end portion 61a of the board body 61 of the front board member 60a from above in the storage 50. It shall act toward

  Here, even if the load W1 acts on the central portion in the left-right direction of the rear end portion 61a of the board main body 61 as described above, the central portion in the left-right direction of the rear end portion 61a of the board main body 61 is shown in FIG. As shown in a), it is located in contact with the lower protruding plate portion 66 of the rear board member 60b from above. Therefore, the load W1 is received from below by the lower protruding plate portion 66 of the rear board member 60b via the central portion in the left-right direction of the rear end portion 61a of the board body 61.

  This means that the load W1 is received from below by both the central portion in the left-right direction of the rear end portion 61a of the board body 61 and the lower protruding plate portion 66 of the rear board member 60b.

  According to this, the left-right direction center part of the rear-end part 61a of the board main body 61 which receives the load W1 will be supported from the downward direction by the lower side protrusion board part 66 of the board member 60b located just under it. Moreover, both board members 60a and 60b are formed of the board material M having high rigidity as described above. Therefore, even if the load W1 acts on the central portion in the left-right direction of the rear end portion 61a of the board main body 61 as described above, the board main body 61 is below the board member 60b in the central portion in the left-right direction of the rear end portion 61a. The original shape can be satisfactorily maintained without being bent downward together with the side protruding plate portion 66.

  Further, for example, the load is not the load W1 but the load W2, as indicated by the arrow F2 in FIG. 8B, from the upper side with respect to the left side portion of the upper protruding plate portion 65 of the rear board member 60b. It shall act toward the inside of the storage 50.

  Here, as shown in FIG. 8B, the left side portion of the upper protruding plate portion 65 of the rear board member 60b is positioned in contact with the left protruding plate portion 63a of the front board member 60a from above. For this reason, when the load W2 acts on the left side portion of the upper protruding plate portion 65 of the rear board member 60b as described above, the load W2 passes through the left side portion of the upper protruding plate portion 65 of the rear board member 60b. It is received from below by the left protruding plate portion 63a of the board member 60a.

  This means that the load W2 is received from below by both the left side portion of the upper protruding plate portion 65 of the rear board member 60b and the left side protruding plate portion 63a of the front board member 60a.

  According to this, the left side portion of the upper protruding plate portion 65 of the rear board member 60b that receives the load W2 is supported from below by the left protruding plate portion 63a of the front board member 60a located immediately below it. Moreover, both board members 60a and 60b are formed of the board material M having high rigidity as described above. Therefore, even if it acts on the left side part of the upper side protruding plate part 65 of the rear side board member 60b to which the load W2 acts as described above, the rear side board member 60b remains on the left side part of the upper side protruding plate part 65. The original shape can be satisfactorily maintained without bending downward together with the left protruding plate portion 63a of the front board member 60a.

  Further, even if the load W2 is different from the above, even if the load W2 acts on the right side portion of the upper protruding plate portion 65 of the rear board member 60b from the upper side toward the inside of the storage case 50, the load W2 is changed to the rear board member 60b. The upper side protruding plate portion 65 and the right side protruding plate portion 63b of the front board member 60a are received from below. Therefore, the rear board member 60b maintains the original shape in the same manner as described above without being bent downward together with the right protruding plate portion 63b of the front board member 60a at the right side portion of the upper protruding plate portion 65. Can do.

As described above, even if the load acts on the portion of the board 60 that is most likely to be bent, for example, as the load W1 or the load W2, the front board 60a or the rear board 60b has a good original shape. Can be maintained. As a result, no matter which part of the board 60 the load acts on from above, the board 60 can serve well as a lid that also serves as a floor member for the storage 50 without being affected by the load. Can be achieved.
(Second Embodiment)
