FIG. 5 is a perspective view of the vehicle 200 as viewed from the rear, showing a state in which the protective sheet 30 is pulled out and laid on the floor of the luggage compartment R. As shown in FIG. FIG. 6 is a perspective view of the vehicle 200 as viewed from the rear, showing a state in which the protective sheet 30 is pulled out to cover the load p placed on the floor of the cargo room R.

As shown in FIGS. 1 and 2, a cover device 100 according to the present embodiment is used for a vehicle 200.
Then, as shown in FIG. 3, the cover device 100 is disposed in the vicinity of the rear bumper 210 in the luggage compartment R of the vehicle 200, and is biased in one direction about the longitudinal axis 10, and the shaft A protective sheet 30 fixed at one end to the shaft 20 and capable of being wound and pulled out with respect to the shaft 20 and the shaft 20 can be made non-rotatable in the winding direction of the protective sheet 30 and freely rotated in the pulling direction. And a one-way clutch 40 (not shown).

The vehicle 200 includes a rear bumper 210, a housing groove 220 for housing the cover device 100, an opening 230, locking grooves 240 provided on both side walls of the loading space R, a groove for knob 250 for housing the knob 32, a number plate 260 and And a unit case 270 housed in the housing groove 220.

The rear bumper 210 is provided at the rear end of the vehicle 200 along the outer shape of the vehicle 200. The rear bumper 210 has a protective member 211 at the upper part, that is, at the lower part of the opening 230 of the vehicle 200. The protective material 211 has, for example, a higher elasticity than the other portions of the rear bumper 210. Thereby, even when the user slides the load p on the upper portion of the rear bumper 210 when the user moves the load p in and out of the loading chamber R, the rear bumper 210 and the load p are not easily damaged since they contact the protective material 211. It can be hard to get dirty. And, even if the protective material 211 is scratched or soiled, it can be replaced with the protective material 211 which is not scratched or soiled, so the rear bumper 210 can be economically maintained in a good-looking state without scratches or dirt. .

The unit case 270 is a box-like body having an elongated opening at the top. The unit case 270 is detachably accommodated in a long and narrow accommodation groove 220 having substantially the same shape as the outer shape of the unit case 270 provided on the floor portion of the luggage compartment R. As a result, since the shaft 20 in a state in which the protective sheet 30 is wound is supported by the shaft support 231 attached to the unit case 270 and stored in the unit case 270, unitization can be performed. Etc. In the case where the bearing portion 231 is directly attached to the housing groove 220 provided in the floor portion of the loading space R, the unit case 270 may be omitted.

The shaft support portion 231 is fixed to both ends in the longitudinal direction of a unit case 270 having a capacity capable of storing the shaft 20 and the protective sheet 30 in a rolled-up state. Then, the shaft support portion 231 rotatably supports the shaft 20.

The shaft 20 is a cylindrical or cylindrical long thin rod. The shaft 20 is rotatably supported by a shaft support 231 provided on the vehicle 200. The shaft 20 is biased in the winding direction around the shaft 10 by a not-shown torsion spring or the like provided so as to apply a torque between the shaft 20 and the bearing 231. One end of a protective sheet 30 is fixed to the shaft 20. Therefore, the protective sheet 30 can be wound around the shaft 20 by rotating the shaft 20 in the winding direction with respect to the shaft 10, and the shaft 20 can be rotated in the pulling direction with respect to the shaft 10. Thus, the protective sheet 30 wound around the shaft 20 can be pulled out.

The protective sheet 30 is a thin strip having flexibility. The protective sheet 30 has one end fixed to the shaft 20 and can be taken up and pulled out of the shaft 20. And the protective sheet 30 is the whole substantially rectangular shape in the state drawn completely.
The protective sheet 30 has one end fixed to the shaft 20 and can be taken up and pulled out of the shaft 20. As a result, when not in use, the shaft 20 can be stored in a compact state in a compact state and can be stored in a space-saving manner, and can be expanded into a rectangular shape when in use.

The other end of the protective sheet 30 has a linear locking rod 31 disposed substantially parallel to the axis 10 of the shaft 20. The locking bar 31 is longer than the width W (see FIG. 6) of the protective sheet 30, and both ends project outward from the width W.
Thereby, as shown in FIG. 2, in a state where the protective sheet 30 is pulled backward from the accommodation groove 220, the locking rod 31 is dropped from the other end of the protective sheet 30 to the outside of the rear bumper 210, and the locking rod 31 By applying the tensile force as a weight, the protective sheet 30 can be expanded rearward by applying a tensile force to the protective sheet 30, and the rear bumper 210 can be widely covered.

The protective sheet 30 also has a knob 32 at the other end. The knob 32 is rotatably provided with respect to the locking bar 31 at the other end of the protective sheet 30. As described above, since the protective sheet 30 has the knob 32 at the other end, as shown in FIG. 1, even if the protective sheet 30 is stored in the accommodation groove 220, the user picks and pulls the knob 32. The protective sheet 30 connected to the knob 32 can be pulled out.

The loading space R has a knob groove 250 such that the upper surfaces of the locking rod 31 and the knob 32 are on the same surface as the upper surface of the floor of the loading space R in a state in which the locking rod 31 and the knob 32 are stored. . Thereby, as shown in FIG. 1, with the locking rod 31 and the knob 32 being accommodated in the accommodation groove 220 and the groove for knob 250, asperity is not generated as much as possible on the upper surface of the floor of the cargo room R. It is possible to make it look neat without hooking the luggage p.

Further, as shown in FIG. 5, in a state where the protective sheet 30 is pulled forward from the accommodation groove 220, the other end of the protective sheet 30 is disposed on the floor portion in front of the luggage compartment R, thereby the protective sheet 30. Can be deployed forward, and the floor of the luggage compartment R can be widely covered.

Furthermore, the locking rod 31 has

hook portions

33 and 34 protruding outward from the width W at both ends. Thus, with the protective sheet 30 being drawn upward from the accommodation groove 220, the hook portion 33 is formed to the locking groove 240 (see FIG. 6) provided in the vicinity of the opening 230 in the both side walls of the luggage compartment R. By locking 34, the protective sheet 30 can be expanded upward, and the load p placed in the cargo room R can be covered, and the state can be maintained.

In addition, when the

hook portions

33 and 34 of the protective sheet 30 are engaged with the locking grooves 240, the protective sheet 30 is the maximum drawing length L which is the length of the protective sheet 30 drawn to the limit from the accommodation groove 220. Alternatively, the opening 230 may not be in contact with a back door (not shown) in a state of closing the opening 230. As a result, the user is able to lock the

hooks

33 and 34 in the locking groove 240, and the load p placed in the load space R is stored in the load space R, that is, the space of the load space R. It can be confirmed that it sticks out from the back door and does not touch the back door.

The protective sheet 30 has a front side 30 a and a back side 30 b which is the opposite side. Then, as shown in FIG. 2, the protective sheet 30 is disposed such that the front and side surfaces 30 a face upward when developed rearward. On the other hand, as shown in FIG. 5, the protective sheet 30 is disposed such that the back surface 30 b faces upward when developed forward.

Moreover, the front side 30a of the protective sheet 30 has a cushioning property higher than that of the back side 30b. Specifically, for example, the front side 30a of the protective sheet 30 has a foamed resin layer. Thereby, as shown in FIG. 2, when the protection sheet 30 is expanded so that the front side surface 30 a faces the center of the opening 230, that is, when the protection sheet 30 is expanded rearward, the user When loading and unloading the load p through the opening 230, the lower portion of the opening 230 and the rear bumper 210 can be protected from scratches and dirt.
On the other hand, the back side 30b of the protective sheet 30 has a higher antifouling property than the front side 30a. Specifically, for example, the back side 30b of the protective sheet 30 may be resistant to adhesion of dirt and moisture by being formed of rubber, or formed of a nonwoven fabric or a woven material formed of a chemical fiber and formed and raised. And an antifouling layer or / and a water repellent layer. Thereby, as shown in FIG. 5, when the protective sheet 30 is expanded so that the back side 30 b faces the center of the opening 230, the floor of the loading space R when the user places the load p in the loading space R We can protect department from wound and dirt.
As described above, since the protective sheet 30 has layers with different functions disposed on the front side surface 30 a and the back side surface 30 b to form one thin strip, the weight can be reduced.

As shown in FIG. 2, the protective sheet 30 has a triangular display unit 35. Specifically, the triangular display unit 35 is arranged such that a hollow erect triangle is displayed on the front surface 30a with the front surface 30a facing the rear with respect to the protective sheet 30. In addition, the hollow erect equilateral triangle portion can be used as the reflection portion so that the color of the reflected light becomes red. As a result, the triangular display unit 35 can be displayed even when it is daytime or nighttime, only by covering the rear bumper 210 by unfolding the protective sheet 30, and the presence of the vehicle 200 from the rear distant place It can be made to recognize.
In addition, as shown in FIG. 2, the triangular display portion 35 is disposed at a position overlapping with the number plate 260 when viewed from the rear in a state of being pulled out rearward, and of the plurality of small holes penetrating the protective sheet 30. It may be formed by a set. Thereby, when the license plate 260 is provided with illumination, the light emitted from the illumination leaks backward through the small holes forming the triangular display portion 35, so even at daytime even in the daytime Also, the triangular display unit 35 can be recognized from a distant place behind. Therefore, when loading and unloading the load p into and from the loading space R, it is possible to reduce the risk of a rear impact by another vehicle.

The one-way clutch 40 can make the shaft 20 non-rotatable in a direction (arrow B in FIG. 3) of winding the protective sheet 30 with respect to the shaft support 231 of the vehicle 200, and pulls out the protective sheet 30 (FIG. The arrow F) in 3 is to be freely rotated.

Specifically, the one-way clutch 40 may be, for example, a ratchet mechanism in which a gear is provided on one of the shaft support portion 231 and the shaft 20 that rotates relative to the shaft support portion 231 and a pawl is provided on the other. In addition, a so-called cam provided with a ball body that moves between a pivoting portion 231 and a shaft 20 that rotate relative to each other between an engagement position transmitting torque between them and a non-engaging position blocking torque between the two. It may be a clutch.
This allows the user to pull out the protective sheet 30 and deploy it to the desired position, ie the desired size, and maintain the protective sheet 30 in that position and in size. Therefore, the vehicle 200 can be stably protected without the protective sheet 30 being unintentionally wound up.

In addition, the one-way clutch 40 is a pawl by moving the pawl or the rotating body directly by the user operating the lever (not shown) from the state of being pulled out and maintained at the desired position and size. Alternatively, the rotor is moved from the engaged position to the non-engaged position, that is, the relative rotation between the shaft support portion 231 and the shaft 20 is free, and the shaft 20 is rotated by the biasing force of a separately provided torsion spring or the like. The protective sheet 30 having one end fixed to 20 may be rewound.

Also, the one-way clutch 40 moves the pawl or the rotating body from the engagement position to the non-engagement position by the user pulling out the protective sheet 30 a little further from the state of being pulled out and maintained in the desired position and size. That is, relative rotation between the shaft support portion 231 and the shaft 20 is freed, and the shaft 20 is rotated by the biasing force of a separately provided torsion spring or the like, and the protective sheet 30 whose one end is fixed to the shaft 20 is wound up. You may

Specifically, for example, the one-way clutch 40 fixes a clutch drum support (not shown) to the shaft 20, and can rotate in the unwinding direction to a shaft support portion 231 for supporting the shaft 20 in a first clutch wheel (not shown) ), And a clutch drum (not shown) supported so as to be able to rotate relative to the first clutch wheel by a predetermined angle coaxially in the clutch drum holder, and the rotating body is fixed to the peripheral wall of the clutch drum It is disposed movably between the engagement position and the non-engagement position, and the clutch drum and the clutch drum receiver are integrally pivoted at the engagement position, and are relatively rotatable at the non-engagement position. .
In addition, the one-way clutch 40 includes a second clutch wheel (not shown) for moving the rotating body to the engaged position or the non-engaged position in the clutch drum. The second clutch wheel rotates relative to the clutch drum in conjunction with the rotation of the shaft 20 in the pull-out direction. A reduction gear (not shown) may be provided between the clutch drum and the shaft 20 to adjust the winding speed of the protective sheet 30.
Then, when the protective sheet 30 is pulled out, the rotating body moves to the engagement position, and the shaft 20 and the clutch drum rotate integrally. When the withdrawal of the protective sheet 30 is stopped, the rotation of the shaft 20 is stopped. Then, when winding up the protective sheet 30 again, when the protective sheet 30 is pulled out a little, the clutch drum does not rotate and only the second clutch wheel rotates, thereby moving the rotating body to the non-engagement position, and pulling out When the force is released, the protective sheet 30 is taken up by the biasing force of the torsion spring.
In this manner, the pulled out protective sheet 30 can be wound by a simple operation, and can be stored again after being used.
