Description

[Detailed description of the invention] <<Industrial application field>> This invention relates to a tonneau board that can be used as a chair and table.

<Summary of the invention> By connecting a reinforcing frame to the foldable leg pieces provided on the underside of the tonneau board, the tonneau board is prevented from folding under load.

《Prior art》 As one of the vehicle tonneau boards installed on the back of the rear seat, foldable leg pieces are provided on the underside of the board part, and the board part can be removed from the vehicle body and the leg pieces can be pulled out to be used as a chair or table. There are also known chairs and tables that can be assembled together.

By the way, the lower part of the tonneau board is used as a storage room for luggage, and the board is lifted from the back of the rear seat to take in and take out luggage. Therefore, in this type of dual-purpose tonneau board, the board portion is supported by a holder provided on the vehicle body, and
The board is divided into two parts, front and back, via a thin hinge.
The front board can be opened and closed using this hinge as the center of rotation, and a pair of U-shaped legs are provided on the underside of the rear board to allow for smooth loading and unloading of luggage. ing.

<<Problems to be solved by the invention>> However, when placing luggage on the tonneau board, this kind of board part is integrally molded with synthetic resin including the thin hinge part, and the board part is attached to the receiving part on the vehicle body side. Since it is only supported by a tool, the strength of the thin hinge part or the center part of the board is weakened.
When a load is applied locally, the shape of the board section is displaced, making it easy to curve downward.

Therefore, an object of the present invention is to eliminate the above-mentioned problems by reinforcing the thin hinge portion or central portion of the board portion without complicating the structure.

<Means for Solving the Problems> In other words, the tonneau board for a vehicle that can be used as both a chair and a table according to the present invention includes a board portion consisting of a pair of boards that are connected together so that they can be folded around a thin-walled hinge portion; A pair of U-shaped legs are rotatably connected to the bottom surface of the board, and are folded and fixed to the bottom surface of the board, and a pin connects each leg piece. A tonneau board that can be assembled into a chair or table with the board part as a board surface by drawing out and crossing the leg pieces in an X shape with the pin center, and a reinforcing frame is connected between one of the leg pieces, and the reinforcing frame is It is characterized in that the central portion is bent into a U-shape, and the U-shaped portion is arranged so as to intersect the rotation center line of the thin hinge portion.

<<Operation>> According to this configuration, in response to an unbalanced load applied to the tonneau board, the reinforcing frame connected between the leg pieces has a U-shaped part formed therein that crosses the center line of the thin hinge part. Since it functions as a reinforcement, there is no possibility that the shape will be particularly displaced in the thin hinge portion or the central portion even if a load is applied locally.

<<Example>> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic side view showing a dual-purpose tonneau board to which the present invention is applied installed on the back of a rear seat. In the figure, the tonneau board 4 that can be used as both a chair and a table includes a board section 5 in which a front board 5F and a rear board 5R are connected via a thin hinge section 4a, and a pair of drawable panels arranged on the bottom surface of the board section 5. It has leg pieces 6 and 7.

Each of the boards 5F and 5R is hollow and lightweight, integrally formed with a thin hinge part 4a by blow molding of synthetic resin, etc., and can be folded freely via the thin hinge part 4a. There is. These boards 5F, 5R are the leg pieces 6,
The rear side board 5R to which 7 is connected is located at the rear of the vehicle, and the front side board 5F is located behind the rear seat. Further, each board 5F, 5R is formed with a protrusion 22 and a locking recess 23 corresponding to the overlapping end when folded (a third
(see figure), the folded state is firmly maintained by fitting the two together. Note that the front side board 5
The locking recess 23 formed in F also serves as a pull part for opening and closing the front board part 5F in order to take in and out luggage from behind the rear seat to the lower part of the board part 5, for example.

FIG. 2 shows the structure of the back side of the tonneau board 4. As shown in FIG. The outer leg piece 6 shown in the figure has a substantially U-shape, and has a pair of brackets 8a on the rear board 5R.
are rotatably connected via. The inner leg piece 7 also has a substantially U-shape, and is rotatably supported by a locking bracket 8b provided on the other side of the rear board 5R when the leg piece 7 is raised up. There is.

In addition, the intermediate portions of each leg piece 6, 7 are rotatably connected by a support pin 9, and the leg tips of each leg piece 6, 7 are connected by a collapsible link 10. 5 can be held at a predetermined expansion angle. Further, both ends of a linear reinforcing frame 11 are fixed to the leg end side of the outer leg piece 6 by welding or the like, thereby reinforcing this portion. Further, both ends of a reinforcing frame 12 are fixed to the pivoting base end of the inner leg piece 7 by welding or the like. Central portion 12a of this reinforcing frame 12
is bent into a U-shape and extends beyond the center line of rotation of the thin hinge portion 4a to the front board portion 5F.

The tonneau board 4 configured as described above has a third
As shown in the figure, the legs 6 and 7 are taken out from the vehicle body, pulled out from the underside of the board section 5, and crossed in an X shape around the support pin 9.
It is assembled into a table with the board portion 5 as a plate surface.

Also, the front side board part 5F is folded via the thin hinge part 4a of the board part 5, and the rear side board 5
If the chairs are overlapped in R and the recesses 23 are fitted into the protrusions 22, a chair with the front side board 5F as a seat will be obtained. In addition, in each figure, the front side board part 5
A pair of cushion bodies 20 are provided on the back surface of F, so that it can be used as a cushioned chair.

In addition, the tonneau board 4 usually has receivers 30 and 31 provided on both sides of the vehicle body, as shown in FIG.
is maintained. It is preferable that the receivers 30 and 31 are set to a size and shape so that they do not get in the way when loading and unloading luggage into the luggage compartment 3 formed at the bottom of the tonneau board 4. Therefore, in the receivers 30 and 31 of the embodiment, the cross section is approximately L
The tonneau board 4 is formed through the outer leg pieces 6.
is becoming increasingly popular.

Therefore, the outer leg pieces 6 and reinforcing frame 11 as described above also have the function of receiving the board portion 5 when the tonneau board 4 is installed and reinforcing the board portion 5 against the load applied to the tonneau board 4.

In addition, the inner leg piece 7 has a support pin 9 as described above.
Since it is connected to the outer leg piece 6 by the link 10, it functions to reinforce the board part 5 like the outer leg piece 6 against the load applied on the tonneau board 4. In this case, when an unbalanced load is applied on the rear board 5R, the leg tip of the inner leg piece 7 is not supported by the receiving part, so a force that tries to swing the leg piece 7 around the support pin 9 is generated. However, since the central portion of the reinforcing frame 12a extends to the floor-side board portion 5R, this force is dispersed and becomes an averaged load.

Furthermore, the reinforcing frame 12 extends beyond the center line of rotation of the thin hinge portion 4a to the front board 5.
Since it is provided so as to extend to F, it effectively functions as a reinforcing material particularly for the center portion or thin hinge portion 4a of this type of tonneau board 4, which is susceptible to uneven loads. Thereby, the cargo can be received over the entire area of the board section 4.

<<Effects of the invention>> As explained above, according to the invention, the weak tonneau board section can be reinforced without complicating the structure, and the load applied to local parts of the tonneau board can be distributed and the loads can be averaged. be able to.

Therefore, in the present invention, the legs of this type of dual-purpose tonneau board can be effectively utilized not only as mere legs but also as rainforths.
