Description

[Detailed Description of the Invention] The present invention relates to a tonneau cover installed as a cover for a luggage compartment provided at the rear of an automobile.

Conventionally, when luggage is loaded into a luggage compartment provided at the rear of an automobile, a method has been adopted in which a tonneau cover that is installed in the seat bag of the rear seat so that it can be rolled up and stored is pulled out and covered.

However, conventional tonneau covers have drawbacks such as the tonneau cover flapping due to the wind or sagging due to the winding spring when the vehicle is driven with the windows open.

This invention was made to improve the above-mentioned drawbacks, and it eliminates the flapping and sagging of the tonneau cover, which can be rolled up and stored in the seat bag of the rear seat, and is useful when covering large items. It is an object of the present invention to provide a tonneau cover device configured so as to cause no problem.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic configuration diagram of the main parts showing an embodiment according to the present invention, and FIG. 2 is an exploded perspective view showing the main parts of FIG. It has a corresponding width, and is wound up and stored in a winding device 3 installed above the seat bag 2 of the rear seat.

Further, a guideway 4 is installed on the rear side of the seat bag 2, and a wire 5 having spring properties, such as a piano wire, is housed in a straight line along the guideway 4, and is attached to the tonneau cover along guide rollers 6a and 6b. It is designed to be pulled out together with 1.

In the extending direction of the above-mentioned tonneau cover 1, polyethylene is placed on the bottom surface when it is pulled out and unfolded.
C-shaped wire storage folds 7 made of elastomer such as polypropylene or nylon are arranged in parallel.
When the tonneau cover 1 is wound up by the winding device 3, it comes off from the wires 5 and becomes flat, and when it is pulled out and unfolded, the wires 5 are arranged in the wire storage folds 7. A vertically divided groove 7a is formed so as to wrap around the.

As shown in FIG. 3 above, a cylindrical body 8 to which the base end of the tonneau cover 1 is fixed; a locking tool 10 which is fixed to the cylindrical body 8 and which locks one end of the coil spring 9;
The other end of the coil spring 9 is locked, the locking tool 10 is rotatably supported, and the seat back 2
The holder 11 is fixed to a frame, etc., and is set in advance by applying a winding force of the tonneau cover 1 to the cylindrical body 8. Note that a spiral spring may be used instead of the coil spring 9.

Further, below the drawer opening for pulling out the tonneau cover 1 from the winding device 3, as shown in FIGS. 4 and 5, a fold opener 13 is installed to guide and wrap the wire 5 in the wire storage fold 7. , the wire storage folds 7 that are wound up in a plane around the cylindrical body 8 are returned to the C shape, and the wires 5 are wrapped inside the vertical grooves 7a of the folds 7 when the tonneau cover 1 is pulled out and expanded. It's getting old. For this reason, the fold opener 13 is arranged so that the storage folds 7 are in an expanded state.
A pair of guide portions 13 for slidingly guiding b.
a, 13a and this pair of guide parts 13a, 13
a separating plate 13 which connects the folds 7 in the expanded state on the upper surface and separates and guides the wires 5 on the lower surface.
b. The distance between the pair of groove-shaped guide portions 13a, 13a is such that the storage direction side of the tonneau cover 1 is gradually separated from each other so that the storage pleats 7 can be expanded. As the tonneau cover 7 is guided in the direction in which the tonneau cover 1 is deployed, it is curved so as to gradually become C-shaped and convex upward. After the pleats 7 guided and pulled out by the pleat opening/closing device 13 pass through the opening/closing device 13, a C-shaped bend is imparted, and the wire 5 is enclosed within the pleats 7.

Next, the operation of the tonneau cover 1 configured as described above will be explained. First, the tip of the wire 5 is fixed to the drawer side end of the tonneau cover 1, and as the tonneau cover 1 is pulled out, the wire 5 is pulled out from the storage section of the seat bag 2.

At this time, as the tonneau cover 1 is pulled out, the wire 5 is removed by the pleat opener 13 installed in the longitudinal groove 7a of the pleat 7.
is wrapped in the vertical grooves 7a of the pleats 7 and functions as a core material of the tonneau cover 1.

Furthermore, when storing the tonneau cover 1, when the hook (not shown) of the tip drawer is removed, the wire 5 is wound up by the spring 9 of the winding device 3, and the wire 5 is moved between the vertical grooves 7a of the pleats 7 and the pleat opener 13. and are automatically stored in predetermined positions in the seat bag 2.

Furthermore, although the pleats 7 are made of synthetic resin elastomer, the wire 5 retains the deflection due to the weight of a normal tonneau cover.
For example, when covering a load that is higher than the position of the tonneau cover 1, depending on the height, the wire 5 may bend or the folds 7 may open to remove the wire 5, and the tonneau cover 1 will extend to cover the load. Cover.

At this time, the wire 5 is exposed, but when the tonneau cover 1 is stored again, it is stored in the same way, and when the tonneau cover 1 is pulled out next time, the pleats 7 wrap around the wire 5 again, and the original purpose can be achieved.

As explained above in detail, the tonneau cover device according to the present invention has one or several folds made of synthetic resin that can be opened and closed in parallel with the direction in which the tonneau cover is extended, and when the tonneau cover is pulled out, The above pleats wrap around the wire, and when it is rolled up, the wires are separated from the folds and stored separately, so when you pull out the tonneau cover to cover your luggage, the tonneau cover will not sag and will not flap around in the wind. It will be resolved.

In addition, when covering luggage, it can be used without any problem even when covering large luggage, and has practical effects.
