Description

The present invention relates to a deck board that forms a floor surface in a deck room provided at the rear of an automobile.

  In automobiles, especially one-box type automobiles such as wagons and hatchbacks, a deck room formed between the rear seat and the back door is used as a luggage storage space. The floor surface of the deck room is generally provided with a relatively rigid plate-shaped molded body, and such a molded body is referred to as a deck board in this specification.

  A storage recess for storing spare tires and tools is usually formed under the deck board. The deck board covers the opening of the storage recess so that it can be opened and closed, and functions as a lid for the storage recess. It also plays a role as the floor surface of the deck room, such as ensuring the flatness of the surface and maximizing the space where luggage can be placed.

The deck board is usually provided with an appearance suitable for the interior material of the deck room by attaching a skin material to the surface of the deck board and imparting design properties. Further, since the conventional deck board is formed such that a resin such as polypropylene is formed in a hollow shape, for example, a pipe-shaped metal reinforcement is inserted inside the deck board as a reinforcing core material. ing. By reinforcing with such reinforcement, the rigidity of the deck board is increased, and even when a relatively large load is applied to the deck board, the deck board is not deformed or broken.

As a conventional deck board, a blown molding method in which a parison formed by melting a thermoplastic resin is arranged between molds and is clamped while air is fed into the parison is known. Yes. In such a deck board, a plurality of reinforcing ribs, which are standing walls that partition the hollow interior of the blow molded body, are formed at predetermined intervals in order to reduce the weight of the hollow board and provide rigidity. Has been done. However, in such a hollow resin molded product, in order to provide the required rigidity, the rigidity is often insufficient only by forming the ribs. In such a case, a reinforcement made of metal such as aluminum is inserted into the hollow molded article to reinforce. As the reinforcement, a pipe-shaped extruded material is used, and the blow molded body is assembled after being formed by blow molding.

The deck board as described above is disclosed in Patent Document 1. The deck board described in Patent Document 1 is a resin hollow body formed by blow molding, and by forming a rib inside the hollow body or by inserting a metal reinforcing material inside the hollow body Improvements in strength and rigidity have been made.
Japanese Patent No. 3564432 (Japanese Patent Application No. 7-336071)

  However, in the above-mentioned hollow resin deck board, assuming a case where the entire weight of the occupant is applied to a part of the deck board, the strength and rigidity are insufficient, and problems such as deformation and cracking may occur. Had. Correspondingly, if the number of reinforcement reinforcements is increased, the assembly man-hour is increased, the weight is increased, and the effect of weight reduction obtained by configuring the deck board with a resin hollow molded product is achieved. It is not suitable for practical use because it is lost and only the complexity of the mounting work increases.

  In addition, if the deck board is made thinner for the purpose of maximizing the storage space for luggage in the deck room, it will be difficult to secure the required rigidity only by reinforcement with ribs or reinforcements. This is an issue.

  In addition, since the deck board is a large molded product that substantially covers the entire floor surface of the car deck room, the resin deck board inevitably undergoes dimensional changes due to shrinkage due to heating and cooling, There is a risk that gaps may occur, causing rattling and abnormal noise, and problems such as poor assembly. In addition, since a resin deck board and a metal reinforcement are combined, deformation distortion due to a difference in shrinkage between the resin and the metal is also a problem.

  Means of the present invention for solving the above problems is a deck board that constitutes a floor surface of a deck room provided behind a rear seat of an automobile and that partitions an opening of a storage recess formed below the floor surface in an openable and closable manner. It is composed of at least two core materials, and these core materials are formed of a flat metal molded product, and the outer surface is covered with a skin material, and the core materials are connected with the skin material. It depends on the deck board that is characterized. Further, the core material is a hollow molded product having an internal space surrounded by an outer wall, and the internal space is preferably partitioned by at least one standing wall portion extending from the outer wall, The material of the extruded member is preferably aluminum.

  In addition, a shielding member is fitted in the opening formed in the end portion of the core member, and the shielding member is a flexible elastic member that extends substantially vertically from the back surface of the flat plate-like general surface. It is preferable that the leg is composed of a leg and a locking claw extending from the tip of the elastic leg, and the end of the skin material is wound and fixed by the shielding member.

  According to the first aspect of the present invention, since the core material of the deck board is made of a flat metal molded product, the strength and rigidity are remarkably improved as compared with the conventional resin deck board. Further, the outer surface of the core material of the deck board according to the present invention is covered with a skin material, and since the core material is connected with the skin material, the connecting portion of the extruded member becomes a hinge, It becomes foldable and can be folded and stored when the deck board is not used. Further, the deck room can be partitioned into various modes by bending the connecting portion.

  According to the invention of claim 2, the core material is a hollow molded product having an internal space surrounded by an outer wall, and the internal space is formed by at least one standing wall portion extending from the outer wall. Since it is partitioned, the deck board can be reduced in weight while maintaining strength and rigidity.

  According to the invention concerning Claim 3, the deck board can be further reduced in weight by making the material of the extrusion-molded member aluminum.

  According to the invention of claim 4, since a shielding member is fitted in the opening formed in the end portion of the core member, when the deck board is installed on the floor surface of the deck room, finger The effect that the designability suitable as an interior material can be provided is obtained.

  According to the invention of claim 5, the shielding member is formed by extending a flexible elastic leg extending substantially vertically from the back surface of the flat plate-like general surface, and extending from the tip of the elastic leg. Since it consists of a locking claw, the elastic leg can be bent inward, inserted into the opening of the core material, and the locking claw can be locked into a locking hole provided in the core material. You will be able to install easily.

  According to the invention of claim 6, since the end of the skin material is entangled and fixed by the shielding member, the end treatment of the skin material can be achieved simultaneously with fitting and fixing the shielding member, Man-hours such as sewing for terminal processing can be reduced.

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

  FIG. 1 is a rear perspective view of a hatchback type automobile suitable for disposing a deck board according to the present invention, and shows a state where a back door is opened. FIG. 2 is a partially enlarged view of the deck board of the present invention as viewed from the left side with respect to the longitudinal direction of the automobile.

  In this type of car, the space between the back of the rear seat and the back door is formed as a space (deck room) for loading luggage, and emergency spare tires and tools are placed on the floor of the deck room. A storage recess is provided for storage, and the deck board is arranged for the purpose of covering the opening of the storage recess so that it can be opened and closed, and ensuring the flatness of the deck room so that luggage can be placed. Established. The deck board generally has a contour substantially along the floor surface of the deck room, has a slightly larger contour than the opening of the storage recess, and is disposed so as to cover the opening of the storage recess. Since the deck board serves as a lid that allows the storage recess to be opened and closed, and the deck board must also have a function as a floor surface for placing the luggage, the weight of the luggage as a whole. The surface is required to be flat and have a strength and rigidity that do not deform.

  FIG. 1 shows an arrangement of a deck board 10 according to the present invention in a deck room 1. The deck room 1 is a luggage provided behind a rear seat 2 of a one-box type automobile having a back door 3. It is a storage space, and the deck board 10 partitions the upper opening of the storage recess for storing spare tires and tools formed in the lower part of the deck room 1 so that it can be opened and closed, and keeps the floor surface of the deck room 1 flat. , Play the role of improving the storage of luggage. A receiving shape for supporting and holding the deck board 10 is formed on both sides of the storage recess.

  FIG. 2 is an enlarged view of a portion on the left side with respect to the traveling direction of the automobile when the deck board 10 is disposed in the automobile deck room. The deck board 10 according to the present invention is composed of three flat core materials indicated by 11 to 13 in FIG. 2, and these core materials are arranged at a predetermined interval, and the front and back surfaces of these core materials are covered with a skin material. It is connected and integrated continuously so as to be wrapped.

  FIG. 3 is a cross-sectional view taken along line aa in the base C of FIG. The core material C of the deck board 10 is an extruded member having a hollow inside, and is formed by melt-molding a metal material in advance, and the strength is increased by forming the standing wall portion 13a. Yes. The cross-section of the core material C shown in FIG. 3 is a horizontally long rectangle as a whole, and includes a peripheral wall forming an outer shape, and two standing wall portions 13a provided at equal intervals inside the peripheral wall. The inside of the peripheral wall is divided into three spaces. 20-100 mm is suitable for the space | interval of an upright wall part, More preferably, 30-70 mm is suitable. This is because if the distance is too large, the strength of the deck board is insufficient, and if the distance is too small, the weight of the deck board becomes too large.

  As for the wall thickness of the said surrounding wall part and the said standing wall part, 1-10 mm is suitable for both. By making the wall thickness 1 mm or more, it will be possible to give sufficient strength to the deck board and prevent deformation as much as possible under load, and to make the wall thickness 10 mm or less. Accordingly, the weight of the deck board can be reduced, and the operability when the deck board is lifted and accessed to the storage recess can be kept good. A strap 15 that functions as a gripping part for the user to open and close the deck board 10 is set on the base 13. The strap 15 is fixed to the back surface of the base 13 with a screw or the like, and is inserted through a through hole provided in the skin material 16 and the core material to be exposed on the surface of the deck board 10.

  As the core material, aluminum is preferably used. However, it can be replaced with a material that is relatively light and has a certain degree of strength, such as a metal such as stainless steel and magnesium. Thus, by forming the core material of the deck board with metal, rigidity and strength are remarkably improved as compared with a conventional resin deck board. In addition, since it is not necessary to insert a reinforcing reinforcement, the effect of reducing the number of mounting steps can be obtained. In addition, since it has high rigidity and strength, the thickness can be reduced compared to conventional resin deck boards, a wider storage space can be secured, and workability is significantly improved when folding the deck board. And when folded and stored, the effect that it can fold more compactly is also acquired.

  A predetermined interval is provided between the three core materials 11 to 13, and the front and back skin materials enclosing the core material are welded to each other to form a joint portion between the core materials. Yes. This joint portion functions as a living hinge that can bend the deck board 10 in the vehicle front-rear direction, and allows one end of the deck board to be folded back so that a part of the storage recess can be accessed.

  The division of the core material is not limited to the three pieces in this embodiment, and it may be constituted by two pieces or four pieces or more depending on the shape and use of the vehicle deck room. It is suitable to divide into at least two core materials in order to take out the stored items in the recesses.

  The core material is obtained when the length of the front core material 11 in the front-rear direction of the vehicle is made larger than the length of the rear core materials 12, 13 and the core materials 12, 13 are folded back as shown in FIG. In addition, it is preferable that this can be placed on the core material 11. Further, the widths of the core members 11 to 13 in the vehicle front-rear direction are set in accordance with the size of the deck floor. In the present embodiment shown in FIG. A recess is provided in a part of the material 12 so as to be fitted into the unevenness formed on the side wall of the deck room so as to be positioned. The thickness of the core materials 11 to 13 is preferably 5 to 30 mm, and more preferably 10 to 15 mm. It is preferable that the thicknesses of the cores are substantially equal so that the top surface of the deck board is flat.

  In this embodiment, the aluminum extrusion-molded member used as the core material is obtained by heating and melting aluminum as a material and extruding it from a die having a required cross-section to be processed and molded as a hollow molded body having the same cross-section. In the present invention, a plurality of hollow extruded bodies are cut into a required length and used in combination. An aluminum extrusion-molded body is light in weight, has a predetermined bending rigidity, is easy to perform post-processing, and is suitable for the present invention. By using a metal hollow molded body as the core material, the thermal shrinkage rate is remarkably smaller than that of the resin core material, and the dimensional stability is remarkably improved.

  The cross section of the extruded member serving as the core is preferably close to a square, but the standing wall and / or the peripheral wall may be formed obliquely to form a combination of triangular cross sections. It is preferable to round the edge part of the peripheral wall a little to eliminate the sharp corners (not shown), thereby improving the safety, improving the touch and making the skin material difficult to break at the edge.

  As shown in FIG. 2, the joint portion of the skin material is provided so as to be flush with the lower surface side of the deck board 10 between the core material 11 and the core material 12, and between the core material 12 and the core material 13. Is preferably provided so as to be flush with the upper surface side of the deck board 10, but is not limited thereto. The space between the core material 11 and the core material 12 may be the upper surface side, and the space between the core material 12 and the core material 13 may be the lower surface side, or both may be provided on the upper surface side or both the lower surface side. It is also preferable to provide a skin material joint at the intermediate height of the core material. When the joint portion of the skin material is provided at the intermediate height of the core material, the joint portion becomes an accent on the design, and the folding position of the deck board is easily understood, thereby improving the convenience for the user.

  Suitable skin materials for covering the core material are those having high tensile strength, low stretchability, and high wear resistance. Specifically, non-woven fabrics, woven fabrics, and resin leathers having a relatively high basis weight. In particular, at the joint of the skin material used as the living hinge of the deck board, the strength and durability may be insufficient, such as the skin material may be stretched or torn. In that case, a reinforcing cloth or a reinforcing sheet may be laminated on the back surface of the joint. Further, a thin reinforcing material may be sandwiched between the skin material and the core material.

When enveloping the core material with the skin material, sandwich it between the skin material on the front side and the skin material on the back side, and bond or fuse them together at the joint between the core materials, etc. Although it is suitable to cover the core material, a single skin material may be folded to enclose the core material. Further, the surface material of the front side and the surface material of the back side may be the same or different materials.

  Caps 14 and 14 ′ shown in FIG. 4 are fitted in the cross-sectional openings at the left and right ends of the cores 11 to 13. The caps 14 and 14 'are set to shield the openings of the core materials 11 to 13 and improve the design of the deck board 10, and FIG. Fig. 4B shows an example of a cap 14 'applied to a core member having a recess formed at the end thereof. .

As the caps 14 and 14 ', resins such as polypropylene, polycarbonate, and nylon are preferably used. However, the caps 14 and 14' are not limited thereto, and metals such as aluminum or various rubber materials may be used.

  On one surface of the caps 14 and 14 ', elastic legs 14a and 14a' that can be bent and deformed are formed to extend in the vertical direction from the general surfaces 14c and 14c 'of the caps 14 and 14'. Locking claws 14b and 14b 'are formed from the tips of 14a and 14a' to the outside of the caps 14 and 14 '. The elastic legs 14a and 14a 'are formed to extend from the vicinity of both ends of the general surfaces 14c and 14c' of the caps 14 and 14 '. In the present embodiment, the three illustrated and the three formed at the ends opposite to these are shown. Is provided.

  5 is a cross-sectional view taken along the line bb of FIG. 2 showing an embodiment in which the cap 14 'is attached to the core member 12. FIG. The elastic leg 14a 'formed on the cap 14' is bent inward at the opening of the core member and is inserted into the hollow portion inside the core member. When the locking claw 14b 'is inserted into a locking hole previously formed in the core member 12, the elastic leg releases the elastic force and expands outward, so that the locking claw 14b' The cap 14 'is fixedly attached to the core member by being locked to the stop hole.

  Various usages are conceivable as usage modes of the deck board of the present embodiment. For example, the core material 11 is erected and fitted into a recess provided on the deck floor, and the connecting portion between the core material 11 and the core material 12 is bent to keep the core material 12 and the core material 13 parallel to the floor surface. It is also possible to use it in such a manner that it is lifted as it is and locked to a receiving portion formed on the deck side to partition the deck room into two stages. In addition, the core material 11 and the core material 12 are folded, and the core material 11 is fitted into a recess formed in the deck floor in a state where the joint portion between the core material 12 and the core material 13 is folded, thereby partitioning the deck room in the front-rear direction. It is also possible to use it.

In addition, since the core material 11 and the core material 13 are folded on the front and back surfaces of the core material 12 to be compact, the deck material can be stored when the deck board is not used, and can be carried and attached. Excellent effects such as easy operability can be obtained.
