Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trunk floor board for an automobile and a mounting structure thereof.

[0002]

2. Description of the Related Art A trunk (including a luggage room) for storing luggage is provided at a rear portion of a vehicle body of an automobile. A spare tire house is provided below the trunk to accommodate a spare tire by making the vehicle body concave. In addition, there is also a car that uses a partial space of a spare tire house to accommodate small items. Then, a flat trunk floor board is installed as a trunk floor above the spare tire house, and a floor mat is further laid thereon. Put luggage on this and use it as a trunk.

[0003] As such a trunk floor board,
Japanese Unexamined Utility Model Publication No. 59-78145 discloses a blow-molded plastic having a hollow double structure, and Japanese Unexamined Patent Publication No. 9-79653 discloses a method of integrally forming a spare tire board by blow molding. A technology is disclosed in which a thin hinge is provided in the portion, and only the rear end portion is rotatable, and the rear end portion of the spare tire house is used as a small container. Also, JP-A-11-20849 discloses A pair of split lids are connected by a hinge at the lower edge, and the upper edge is an overhanging butted part, so that there is no problem even if luggage is placed on the lid, opening it so that only the surface of the lid can be seen. Techniques that can be closed are described.

[0004]

However, in the above-mentioned prior art, for example, in Japanese Patent Application Laid-Open No. 9-79653, it is sufficient to open and close only the rear board when taking out small articles. It is necessary to remove all the luggage on the board and remove the entire board, and there is no description of a tool storage section for tire replacement. Although the structure of the hinge portion is not described in this publication, it is not clear, but generally, such a thin hinge that turns a part of the board upward is almost equivalent to its thickness in a flat state where the board is not turned. Because of this, there is a danger that when luggage is placed on it, it will become unstable and roll during running.
Further, in the technology described in JP-A-11-20849,
Since the lid cannot be opened with the luggage placed in front of the lid, it is necessary to open the lid after lowering the luggage.
Further, the above three prior arts do not disclose a stopper that does not close when the lid is opened, and prevent the closed lid from opening due to sudden braking or collision. There is no disclosure of any means for fixing the lid.

An object of the present invention is to provide a trunk floor board for an automobile and a mounting structure thereof, which have a simple structure, high rigidity, allow easy replacement of spare tires, and can be fixed when closed.

[0006]

According to a first aspect of the present invention, there is provided a vehicle for closing a concave storage section formed on a trunk floor of an automobile for storing spare tires, small articles, and the like. An openable and closable floor board comprising a blow-molded plate-like hollow molded body, wherein a front non-rotating board and a rear turning board are integrated with each other by a thin hinge extending in the vehicle width direction. While the rear end of the rotating board pivots upward with the hinge as an axis, the hinge is located near the center in the front-rear direction of the floorboard, and has a thickness of the floorboard near the hinge from the upper side of the floorboard. A hinge which is formed at a portion of 1/2 or less, has a turning angle of the turning board of 90 degrees or more, and forms a hinge recess when the turning board has completely turned upward. A trunk floor boards, automobile, characterized by forming a pair of stoppers to hold the rotating board upright in contact side walls to one another.

[0007] With this configuration, since it is made of a plate-shaped hollow molded body obtained by blow molding, a floorboard having a simple structure, light weight, and high rigidity is obtained. The cross-sectional structure of this hollow molded body is composed of two plates, an upper wall and a lower wall. Further, since the front non-rotating board and the rear turning board are integrally formed by thin hinges extending in the vehicle width direction so as to be integrated with each other, manufacturing and assembly costs can be reduced. Since the thin hinge is located near the center of the floorboard in the front-rear direction, the rear half of the floorboard can be pivoted and lifted upward, and the spare tire can be taken out. This can be done with the luggage on the front half of the floorboard. Here, the vicinity of the center in the front-rear direction of the floorboard with a thin hinge means
The center and its vicinity may be any position as long as the rear half of the floorboard is pivoted and lifted up so that a spare tire can be taken out. Furthermore, since the thin hinge is formed in a portion of the floorboard upper surface side closer to the hinge and less than half of the floorboard thickness from the upper surface side, when the mat or the sheet is laid on the upper surface of the floorboard, there is little drop in the hinge portion, There are few irregularities on the floor, the appearance is good, and luggage can be stably loaded. Here, the floor board thickness near the hinge is the thickest portion in a portion extending from the hinge forward to one third of the length of the non-rotating board. In general, the thickness of the floorboard is constant except for hinges and recesses described later. The position of the thin hinge is required to be less than half the thickness of the floor board near the hinge from the top side of the floor board in consideration of the flatness of the floor and the stable standing state described later. From the viewpoint of the balance between the properties and the stable standing state described later, it is preferable that the ratio is 1/2 to 1/8.
In addition, here, the concave storage portion formed on the trunk floor may be called a spare tire house and may store spare tires and small articles, but may have a structure that stores only spare tires.

[0008] When the rotation angle of the rotation board is 90 degrees or more, and the rotation board has completely rotated upward, the walls on both sides of the hinge forming the hinge concave portion come into contact with each other and rotate. By forming a pair of stoppers for holding the moving board in the upright state, the rotating board stably stands up in the open state. This is because, by setting the rotation angle to 90 degrees or more, when the rotation board has completely rotated upward, the center of gravity of the rotation board is located forward of the hinge portion. Here, the turning angle refers to an angle at which the turning board is turned around the hinge portion from the state in which the turning board closes the concave storage portion as shown in FIG. Since the upright state of the turning board is held by the stopper in this way, it is easy to reach from the rear side of the automobile and to bring the turning board in the upright state to the closed position. From the viewpoint of workability, the rotation angle is preferably 90 to 130 degrees. The walls on both sides of the hinge forming the hinge recess are in contact with each other and function as a pair of stoppers, but the contact between the pair of stoppers is more linear than point-like contact in order to maintain a stable standing state. Preferred, more preferably planar contact.

According to a second aspect of the present invention, there is provided an openable and closable floor board for closing a concave storage portion formed on a trunk floor of an automobile for storing spare tires, small articles and the like. The front non-rotating board and the rear turning board are connected to each other by a thin hinge extending in the vehicle width direction so as to be integrated with each other, and are turned around the hinge as an axis. While the rear end of the moving board pivots upward, a recessed part for fixing the rotating board in which an upper wall and a lower wall are integrally overlapped to form a bottom wall is formed at an intermediate portion in the front-rear direction of the rotating board. Formed on the trunk floor board of an automobile,
It is.

The turning board has a concave portion for fixing the turning board, in which an upper wall and a lower wall are integrally overlapped with each other and a bottom wall is formed at an intermediate portion in the front-rear direction. When a bolt connection is used for fixing, firm fixing can be easily performed. That is, if the concave portion for fixing the rotating board has a double structure of the upper wall and the lower wall, when the space between the upper wall and the lower wall is closed when the bolt and the nut are fixed, the space between the upper wall and the lower wall is reduced. It is difficult to make a firm fixation. If the fixing portion is a concave portion, the fixing nut can be accommodated in that portion, and the flatness of the floorboard is not impaired.

According to a third aspect of the present invention, there is provided an automobile according to the second aspect, wherein a tool storage portion is recessed in at least one of an upper surface and a lower surface of the rotating board. Trunk floorboard.

With such a configuration, the tool is stored on the floor and can be taken out immediately when needed. In particular, if the tool for replacing a spare tire is stored, the efficiency of the replacement work is increased.

According to a fourth aspect of the present invention, there is provided a floor board mounting structure for opening and closing a concave storage portion formed on a trunk floor of an automobile for storing spare tires, small articles, and the like. The floorboard is made of a blow-molded plate-shaped hollow molded body, and the front non-rotating board and the rear turning board are connected to each other by a thin hinge extending in the vehicle width direction, so that they are integrated with each other, The rear end of the pivot board pivots upward with the hinge as an axis, and a bottom wall is formed by an upper wall and a lower wall integrally overlapping at the middle part in the front-rear direction of the pivot board. A recess for fixing a board is formed, and the recess is fixed to a mounting member for fixing a spare tire stored in the concave storage portion by a fixture. Structure, it is.

With such a structure, it is not necessary to provide and fix the mounting member for fixing the spare tire and the mounting member for fixing the turning board in separate places, so that the space can be effectively used. The removal of the fixed fixture of the rotating board and the removal of the fixed member of the spare tire can be performed in the same working state, and the work is facilitated. Also, the fixing of the spare tire is usually performed by passing a bolt through the hole in the center part, but a small diameter screw is provided on the fixing bolt of the spare tire, and the spare tire is fixed there by the nut of the fixing fixture of the turning board. The method is preferable because of its simple structure.

[0015]

According to the present invention, therefore, only the rear half of the floorboard is turned upward while the load is loaded on the front half of the floorboard, and the turning board remains stable even when the hand is released. As a result, the work of removing the spare tire can be performed easily and efficiently, and the concave storage portion can be easily closed. In addition, because the flatness of the upper surface of the floor is good, the floor is beautiful and does not get damaged or fall down when loading luggage. And since it is a lightweight and highly rigid floorboard, the floorboard can be easily rotated and a heavy object can be loaded on the trunk.

Further, since the concave portion for fixing the rotating board is formed as a point at the bottom wall where the upper wall and the lower wall are integrally overlapped with each other, the fixing of the rotating board can be easily performed, and the tool storage portion can be provided. Since the rotating board is recessed on at least one of the upper surface and the lower surface, it is easy to insert and remove the tool, and the recess for fixing the rotating board is fixed to the mounting member for fixing the spare tire with the mounting tool That the removal of the fixed fixture of the rotating board and the removal of the fixed member of the spare tire can be performed in the same working state,
With the above three points, these tasks can be performed quickly with a small amount of work, and only use a small force.

[0017] Since the concave portion for fixing the rotating board is fixed to the mounting member for fixing the spare tire by the mounting tool, the space can be effectively used in both the trunk room and the spare tire house. Since the turning board is fixed as described above, the turning board does not open at the time of sudden start, sudden braking, collision, or the like.

[0018]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a trunk, 2 denotes a concave storage portion for storing a spare tire 3 provided on a floor panel 19, and 10 denotes a seat.

The floor board 20 includes a front non-rotating board 5 and a rear turning board 4, and a floor mat 14 is laid thereon to improve the appearance. The non-rotation board 5 and the rotation board 4 are connected by a thin hinge 6 extending in the vehicle width direction near the center of the floor board 20.

The floorboard 20 is formed by blow molding a synthetic resin such as polypropylene, glass fiber reinforced polypropylene, ABS, HDPE, or polyamide into a hollow double molded body.
6 The upper wall 15 side is provided with a later-described turning board fixing recess 8 and a tool storage section 9, an insertion hole 18 into which a hand is inserted when lifting the turning board 4, and a mounting section 21 for attaching the non-turning board to the vehicle body. Flat except for the lower wall 1
6, a large number of concave ridges 24 are formed which are concave upward and extend in the vehicle width direction to increase the strength. A portion where the upper wall 15 and the lower wall 16 are in contact is connected at a plurality of spots.
In the hinge 6, the floor board 20 is single.

The front end of the rotating board 4 and the rear end of the non-rotating board 5 on the upper wall 15 are inclined downward toward the hinge 6 to form a hinge recess 25. The inclined surfaces on both sides of the hinge 6 forming the hinge recess 25 constitute a pair of stoppers 7 for holding the rotating board 4 in an upright state. That is, the rotation board 4 is pivoted on the hinge 6 as a fulcrum.
Is rotated to the position 4b, the pair of stoppers 7 forming the hinge recess 25 come into contact with each other and stop rotating,
And it is held upright. FIG. 2 shows an enlarged view of the vicinity of the hinge 6. If the rotation angle θ is 90 degrees or more, the center of gravity of the rotation board 4b is located ahead of the hinge 6 in a state where the stoppers 7 are in contact with each other. Maintain the standing state without falling down. Here, the rotation angle θ may be 90 degrees or more,
Considering the case where the rotating board 4 is returned from the standing state to the closed position 4a, if the angle is too large, the rotating board 4b cannot be reached. Therefore, the rotating angle θ is preferably 90 to 130 degrees.

The amount of depression t of the hinge 6 from the upper surface of the floorboard 20 is not more than 1/2 of the thickness T of the floorboard near the hinge. The smaller the dent amount t, the better the floorboard becomes flat, but if it is too small, the stopper wall 7 does not work effectively.
