The net holders 25 include a first net holder 25A, a second net holder 25B, a third net holder 25C, and a fourth net holder 25D. The first net holder 25A is located adjacent to and below the tonneau cover holder 24. The second net holder 25B is located at the lower end of the storage space S1 (adjacent to the top surface 14A of the floorboard 14). The third net holder 25C is located more to the rear of the vehicle 10 than the second net holder 25B, more specifically, at the rear of the storage space S1 (close to the edge of the rear opening 12). The fourth net holder 25D is located more to the front of the vehicle 10 than the second net holder 25B, more specifically, at the front end of the storage space S1. In the following description, the net holders 25 are referred to as the first to the fourth net holders 25A to 25D to describe them individually and referred to as the net holders 25 to describe them without discriminating from one another.
As illustrated in FIG. 5, each of the net holder 25 includes a fixed portion fixed to the cargo side-trim 20 and a hooking portion in a D-ring shape and attached to the fixed portion. The hooking portion is rotatable with a linear portion as a rotary axis.
As illustrated in FIGS. 2 to 4, the tonneau cover 31 includes a screen having flexibility. The tonneau cover 31 is a rectangular member having light blocking properties, for example, an artificial leather sheet made of synthetic resin. The tonneau cover 31 includes a sheet surface 31C. The tonneau cover 31 may be placed such that the sheet surface 31C extends in the front-rear direction of the vehicle 10 to cover the cargo area 11 and hide the cargo stored in the cargo area 11. The tonneau cover 31 includes a first end 31A fixed to the tonneau cover winding rod 34. The tonneau cover 31 includes a second end 31B that is a free end and to which the handle 32 is fixed. The handle 32 has a long plate shape. The user can hold the handle 32 for deploying or retracting the tonneau cover 31. When the tonneau cover 31 is deployed, the handle 32 is held with the tonneau cover holder 24. In this condition, the handle 32 functions as a frame for holding the tonneau cover 31 deployed. When the tonneau cover 31 is retracted in the case 40 (the tonneau cover 31 is rolled up with the tonneau cover winding rod 34), the handle 32 is held against an outer surface of the case 40 (an edge of a tonneau cover case opening 41A). The user can hold the handle 32 without inserting his or her fingers or hand into the case 40 to pull the tonneau cover 31 out of the case 40.
As illustrated in FIG. 6, the tonneau cover winding rod 34 is configured to roll up the tonneau cover 31 from the first end 31A. The user can pull the tonneau cover 31 out of the case 40 when needed. The tonneau cover winding rod 34 is a column placed in a horizontal position so as to extend in the width direction of the vehicle 10. The tonneau cover winding rod 34 is rotatable with a rotary axis (an axis thereof) aligned with the width direction of the vehicle 10. The tonneau cover winding rod 34 includes a rotary winding mechanism that includes a spring. The rotary winding mechanism applies a force to the tonneau cover 31 in a winding direction (a counterclockwise in FIG. 6). In FIG. 6, the tonneau cover 31 around the tonneau cover winding rod 34, that is, retracted in the case 40 is indicated with a two-dot chain line.
As illustrated in FIGS. 2 to 4, the net 36 includes a screen having flexibility. The net 36 is a woven screen having flexibility higher than the tonneau cover 31. The net 36 has a rectangular shape in a plan view. A dimension of the net 36 in the front-rear direction of the vehicle 10 is larger than a dimension between the case 40 and the first net holder 25A, that is, larger than the tonneau cover 31 (see FIG. 2). A dimension of the net 36 in the width direction of the vehicle 10 is smaller than the tonneau cover 31 so that interference between the net 36 and the wheel housing portion 21 is less likely to occur (see FIG. 1). According to the configuration, the net 36 can be arranged in various positions in the cargo area 11 to arrange the layout of the cargo area 11 in various ways. Layout variations of the cargo area 11 with the net 36 will be described layer.
As illustrated in FIGS. 1 and 6, the net 36 includes a first end 36A fixed to the net winding rod 39 and a second end 36B. Hooks (screen holding pieces) 37 are fixed to side edges of the second end 36B, respectively. The hooks 37 are fixed to corners of the second end 36B of the net 36 via components having flexibility such as rubbers. The hooks 37 are configured to hook to the respective net holder 25 for holding the second end 36B of the net 36 at the positions of the net holder 25 with respect to the front-rear direction of the vehicle 10. When the net 36 is retracted in the case 40 (or rolled up with the net winding rod 39), the hooks 37 project from the case 40 and thus the user can hold the hooks 37 to pull the net 36 out of the case 40.
As illustrated in FIG. 6, the net winding rod (a screen winding rod) 39 is configured to roll up the net 36. The user can pull the net 36 out of the case 40. The net winding rod 39 is a column placed in the width direction of the vehicle 10. The net winding rod 39 is rotatable with a rotary axis (an axis thereof) aligned with the width direction of the vehicle 10. The net winding rod 39 includes a rotary winding mechanism that includes a spring. The rotary winding mechanism applies a force to the net 36 in a winding direction (a counterclockwise in FIG. 6). In FIG. 6, the net 36 rolled up with the net winding rod 39, that is, retracted in the case 40 is indicated with a two-dot chain line. When retracted in the case 40, an outer diameter of the net 36 is larger than an outer diameter of the tonneau cover 31.
As illustrated in FIG. 6, the case 40 is configure to hold the tonneau cover winding rod 34 and the net winding rod 39 therein. The case 40 has a function for integrating the tonneau cover 31 and the net 36 into a single unit and collectively handling the tonneau cover 31 and the net 36. The case 40 includes a tonneau cover case 41, a net case 42, and an outer case 43. The tonneau cover case 41 made of aluminum holds the tonneau cover winding rod 34 therein. The net case 42 made of aluminum holds the net winding rod 39 therein. The outer case 43 made of synthetic resin holds the tonneau cover case 41 and the net case 42 therein. The outer case 43 defines an outer surface (or a design) of the tonneau cover assembly 30.
As illustrated in FIG. 1, the outer case 43 of the case 40 is a rectangular pipe. The outer case 43 is configured to be installed in the cargo area 11 with the long axis thereof aligned with the width direction of the vehicle 10. The case 40 includes side portions 41B that are sidewalls of the portion of the case 40 in which the tonneau cover winding rod 34 is held. The side portions 41B are pressed against the cargo side-trims 20 with forces applied thereto in the width direction of the vehicle 10. The case 40 can be extended or shortened and thus the side portions 41B can be fitted in the case mounting portions 23 in the respective side-trims 20. According to the configuration, the case 40 can be easily mounted or removed from the cargo side-trims 20. The top surface 40A of the case 40 is configured to be flush with the sheet surface 31C of the tonneau cover 31 when the tonneau cover 31 is deployed and to cover the cargo area 11 together with the tonneau cover 31.
As illustrated in FIG. 6, the case 40 includes a tonneau cover case opening 41A, a net case opening 42A (an opening for releasing the screen out of the case), and an outer case opening 43A. The tonneau cover case opening 41A opens toward the rear of the vehicle 10 and the net case opening 42A opens toward the bottom and the rear of the vehicle 10 when the case 40 is installed in the cargo area 11. The tonneau cover case opening 41A is for releasing and retracting the tonneau cover 31. The net case opening 42A is for releasing and retracting the net 36. The outer case opening 43A is formed in the outer case 43. The tonneau cover case opening 41A and the net case opening 42A are arranged in the outer case opening 43A so as to extend parallel to each other. The outer case opening 43A is formed as if a rear wall located closer to the rear of the vehicle 10 and a lower wall closer to the bottom of the vehicle are cut. The tonneau cover case opening 41A is formed as if a rear wall located closer to the rear of the vehicle 10 is cut. The net case opening 42A is formed as if a rear wall located closer to the rear of the vehicle 10 and a lower wall located closer to the bottom of the vehicle 10 are cut.
Next, a relationship between the tonneau cover 31 and the net 36 and a relationship between the tonneau cover winding rod 34 and the net winding rod 39 will be described with reference to FIG. 6.
In the case 40, the net winding rod 39 is located more to the front of the vehicle 10 than the tonneau cover winding rod 34. An upper end of the net winding rod 39 is positioned lower than an upper end of the tonneau cover winding rod 34 and higher than a lower end of the tonneau cover winding rod 34. The tonneau cover winding rod 34 is configured to release the tonneau cover 31 at a portion thereof located higher than a portion of the screen winding rod at which the screen winding rod releases the screen. The tonneau cover winding rod 34 is configured to release the tonneau cover 31 at an upper portion thereof when the tonneau cover 31 is pulled toward the rear of the vehicle 10. The net winding rod 39 is configured to release the net 36 at a lower portion thereof when the net 36 is pulled toward the rear of the vehicle 10. A winding direction in which the net winding rod 39 rotates to roll up the net 36 is opposite to a winding direction in which the tonneau cover winding rod 34 rotates to roll up the tonneau cover 31. A position at which the tonneau cover 31 comes out of the case 40 is higher than a position at which the net 36 comes out of the case 40.
Next, the layout variations of the cargo area 11 with the net 36 will be described with reference to FIGS. 2 to 4.
Arrangements of the net 36 include a horizontal arrangement, a vertical arrangement, and a front horizontal arrangement. In the horizontal arrangement, the net 36 is placed in the horizontal position (see FIG. 2), that is, the net 36 horizontally spreads. In the vertical arrangement, the net 36 is placed in the vertical position (see FIG. 3), that is, the net 36 vertically spreads. The direction in which the net 36 spreads in the horizontal arrangement crosses the direction in which the net 36 spreads in the vertical arrangement. In the front horizontal arrangement, the second end 36B of the net 36 is hooked to the backrest 16A and the net 36 extends from the case 40 toward the front of the vehicle 10 such that a portion of the net 36 spreads horizontally (see FIG. 4).
In the horizontal arrangement illustrated in FIG. 2, the net 36 is pulled toward the rear of the vehicle 10 and the hooks 37 are hooked to the respective first net holder 25A. When an article P is placed on the net 36, a force is applied to the net 36 in a direction opposite to a direction in which the net 36 is rolled up by the net winding rod 39 due to the weight of the article P and thus the net 36 becomes loose. With the net 36 in the horizontal arrangement, an upper portion of the storage space S1 of the cargo area 11 which tends to be dead space is provided as additional storage space S3. The tonneau cover 31 can be pulled toward the rear of the vehicle 10 without interfered by the net 36 to arrange the net 36 in the horizontal position. When the tonneau cover 31 is deployed while the net 36 is in the horizontal position, the additional storage space S3 is covered with the tonneau cover 31, that is, the article P in the additional storage space S3 is hidden from view from outside. According to the configuration, the additional storage space S3 has a proper level of security.
To arrange the net 36 in the vertical position illustrated in FIG. 3, the net 36 is pulled toward the bottom of the vehicle 10 and the hooks 37 are hooked to the respective second net holder 25B. With the net 36 in the vertical arrangement, the storage space S1 of the cargo area 11 is divided into front storage area and rear storage area. The arrangements of the net 36 further include an oblique arrangement. In the oblique arrangement, the hooks 37 are hooked to the respective third net holder 25C. A cargo placed on the top surface 14A of the floorboard 14 can be covered with the net 36 in the oblique arrangement to restrict the cargo from shifting toward the rear opening 12. The arrangements of the net 36 include another vertical arrangement. In the other vertical arrangement, the hooks 37 are hooked to the respective fourth net holder 25D. With the net 36 in the other vertical arrangement, the passenger compartment is separated from the cargo area 11. The tonneau cover 31 can be pulled out without interfered by the net 36 in any of the vertical arrangements or the oblique arrangement.
In the front horizontal arrangement illustrated in FIG. 4, the net 36 is pulled down and then toward the front of the vehicle 10 and the hooks 37 are hooked to the net holder 16B on the rear surface of the backrest 16A. The net 36 in the front horizontal arrangement extends across space between the case 40 and the rear surface of the backrest 16A. The article P can be placed on the net 36 in the front horizontal arrangement. A passenger can easily access the article P placed on the net 36 in the front horizontal arrangement from the passenger compartment. Furthermore, the tonneau cover 31 can be pulled toward the rear of the vehicle 10 without interfered by the net 36 in the front horizontal arrangement.
Next, functions and effects of the tonneau cover assembly 30 will be described.
According to the tonneau cover assembly 30, the tonneau cover 31 is released from the case 40 at the position higher than the net 36. Therefore, the tonneau cover 31 is less likely to be interfered by the net 36 that can be placed in various arrangements when covering the cargo area 11 with the tonneau cover 31. With the net 36 that is pulled toward the rear of the vehicle 10 and placed in the horizontal position, the layout of the cargo area 11 is arranged such that an article placed on the net 36 can be covered with the tonneau cover 31. Namely, the layout of the cargo area 11 is arranged in various ways according to intended use.
The tonneau cover winding rod 34 is located closer to the top of the vehicle 10 than the net winding rod 39. According to the configuration, the tonneau cover 31 is released from the case 40 at the position higher than the net 36. The net winding rod 39 is positioned so as to overlap the tonneau cover winding rod 34 when viewed from the front of the vehicle 10. In comparison to a configuration in which the net winding rod 39 is positioned so as not to overlap the tonneau cover winding rod 34 when viewed from the front of the vehicle 10 and the lower end of the tonneau cover winding rod 34 is located higher than the upper end of the net winding rod 39, a dimension of the tonneau cover assembly 30 measuring in the vertical direction is reduced. Therefore, the tonneau cover assembly 30 is easily stored in the underfloor storage space S2 (or the tonneau cover assembly storage space 18), a depth of which measuring in the top-bottom direction of the vehicle 10 is limited.
The tonneau cover winding rod 34 is configured to release the tonneau cover 31 at the upper portion thereof when the tonneau cover 31 is pulled toward the rear of the vehicle 10. The net winding rod 39 is configured to release the net 36 at the lower portion of the net winding rod 39. The tonneau cover winding rod 34 releases the tonneau cover 31 at the position thereof located higher than the position of the net winding rod 39 at which the net winding rod 39 releases the net 36. According to the configuration of the tonneau cover assembly 30 in which the tonneau cover 31 is pulled toward the rear of the vehicle 10, the tonneau cover 31 is properly released from the case 40 at the position higher than the position at which the net 36 is released from the case 40.
The net case opening 42A opens toward the bottom and the rear of the vehicle 10. Therefore, the net 36 can be pulled in various directions between the vertical direction toward the bottom of the vehicle 10 and the horizontal direction toward the rear of the vehicle 10 to arrange the layout of the cargo area 11. In a configuration in which a net case opening opens only toward a rear of a vehicle, the net case may be an obstacle to pullout of a net toward the bottom of the vehicle. According to the configuration of this embodiment, the case 40 does not interfere with the pullout of the net 36 toward the bottom or the rear of the vehicle 10. Therefore, the net 36 can be easily placed in any of the horizontal arrangements, the vertical arrangements, and the oblique arrangement.
The net 36 can be placed in the horizontal arrangements, the vertical arrangements, and the oblique arrangement. In the horizontal arrangements, the net 36 horizontally spreads. In the vertical arrangements, the net 36 vertically spreads. In the oblique arrangement, the net 36 obliquely spreads. When the net 36 is placed in the horizontal arrangements, the net 36 can be used as a net rack, for example, the article P can be placed on the net 36. When the net 36 is placed in any of the vertical arrangements and the oblique arrangement, the net 36 can be used as a partition to divide the cargo area 11. With the net 36, the layout of the cargo area 11 can be arranged in various ways.
The net 36 is more flexible than the tonneau cover 31. When the article P is placed on the net 36 that is pulled toward the rear of the vehicle 10 and arranged in the horizontal position, the net 36 becomes loose. When the tonneau cover 31 is deployed to cover up the article P, the storage space S3 is provided between the net 36 and the tonneau cover 31 because the net 36 is loose. Furthermore, because the net 36 is flexible, the net 36 can be placed in various positions and thus the layout of the cargo area 11 is arranged in various ways.
Second Embodiment
A second embodiment will be described with reference to FIG. 7. A tonneau cover assembly 130 includes a case 140 that includes rollers 45. Configurations, functions, and effects similar to those of the first embodiment will not be described.
The case 140 includes the rollers 45 at a lower edge of the net case opening 42A. The rollers 45 are configured to rotate in a direction in which the net 36 is pulled out and in a direction in which the net 36 is rolled up. The rollers 45 are disposed at intervals in the width direction of the vehicle 10. Rollers 45 are configured to rotate on the net 36 as the net 36 is pulled or rolled up to reduce friction between the net 36 and the case 140.
Pullout of the net 36 toward the bottom or the front of the vehicle 10 may be interfered by the case 140. According to the configuration of this embodiment, the interference is less likely to occur and thus the net 36 can be easily pulled out. The net 36 can be easily placed in various positions and the layout of the cargo area 11 is easily arranged in various ways.

A third embodiment will be described with reference to FIG. 8. A tonneau cover assembly 230 includes a case 240. Configurations, functions, and effects similar to those of the first embodiment will not be described.
The case 240 is a single case that does not include other cases for holding the tonneau cover winding rod 34 and the net winding rod 39, respectively, such as the tonneau cover case 41 and the net case 42 in the first embodiment. The case 240 holds the tonneau cover winding rod 34 and the net winding rod 39 therein. The case 240 includes an opening 240A that extends from an upper rear to a lower front of the case 240. Namely, the opening 240A is formed as if a portion of the case 240 between the upper rear and the lower front is cut. The opening 240A includes an upper portion through which the tonneau cover 31 is pulled out and a lower portion through which the net 36 is pulled out.
