This application claims priority from Japanese Patent Application No. 2016-012421 filed on Jan. 26, 2016, the entire contents of which are incorporated herein by reference.
The present invention relates to a tonneau cover device that pulls out and winds a tonneau cover which covers a cargo chamber of a vehicle.
For example, a cargo chamber of a vehicle such as a wagon vehicle and a hatchback vehicle is covered with a tonneau cover. The tonneau cover is pulled out and wound by a tonneau cover device as necessary.
JP-H10-250483-A describes a tonneau cover device that includes a cover main body, end caps attached to a pull-out end of the cover main body, and side trims provided to both sides of a cargo chamber, the side trims including engagement holes into which the end caps drop to be engaged therewith. The engagement holes include opening portions that are opened on the upper surfaces of the side trims, and engaging portions inside the engagement holes that are horizontally long to the front side of the vehicle. Meanwhile, the end caps include hook portions on their lower sides that are bent in an L-shape.
When the cover main body is pulled out a given length toward the rear side of the vehicle while the end caps slide on the upper surfaces of the side trims, the hook portions of the end caps drop in the engagement holes through the opening portions to get in to be engaged with the engaging portions, whereby the cover main body is maintained in a pull-out state. On the other hand, by pulling up the end caps in this state to pull the hook portions out of the engagement holes, the cover main body is wound by a known winding spring.
In the above-described tonneau cover device, when winding the cover, the operation of pulling the distal end portion of the cover in the direction orthogonal to the pull-out direction of the tonneau cover, i.e., upward to pull the hook portion of the end cap out of the engagement hole, is required, so that there causes a trouble in winding workability of the tonneau cover when a user has baggages with both hands.
One object of the present invention is to provide a tonneau cover device capable of winding a tonneau cover with simple operation.
One aspect of the present invention provide
a tonneau cover device including:
a tonneau cover provided to cover a cargo chamber of a vehicle and configured to be pulled out from a wound state;
a fixing device attached on both sides of the tonneau cover at one end thereof toward a pull-out direction; and
a cover-urging mechanism configured to urge the tonneau cover in a winding direction that is opposite to the pull-out direction,
wherein a locking portion is provided on a sidewall of the cargo chamber and configured to be engageable with the fixing device on the tonneau cover when the tonneau cover is pulled out against an urging force of the cover-urging mechanism to thereby hold the tonneau cover at a pulled-out position,
wherein the fixing device includes:
wherein, when a force is exerted on the engagement protruding portion as a result of pushing in the tonneau cover toward the winding direction from a pulled-out-and-held state where the engagement protruding portion is engaged with the locking portion and the tonneau cover is held at the pulled-out position, and the exerted force acting on the engagement protruding portion is larger than the urging force of the cover-urging mechanism acting on the engagement protruding portion, the hook swings such that the engagement protruding portion retracts into the case while causing the slider to be pushed in away from the sidewall through the conversion mechanism, thereby being disengaged from the locking portion.
The present invention may further provide
the tonneau cover device,
wherein a sliding amount of the slider to be away from the sidewall when the engagement protruding portion is pressed toward the pull-out direction to cause the hook to swing as a result of pushing in the tonneau cover toward the winding direction from the pulled-out-and-held state to thereby be disengaged from the locking portion is a first sliding amount,
wherein a sliding amount of the slider to be away from the sidewall when the engagement protruding portion is pressed toward the winding direction to cause the hook to swing as a result of pulling out the tonneau cover toward the pull-out direction from the pulled-out-and-held state to thereby be disengaged from the locking portion is a second sliding amount, and
wherein the first sliding amount is larger than the second sliding amount.
The present invention may further provide
the tonneau cover device,
wherein the conversion mechanism includes:
wherein the shaft portion includes:
wherein the groove portion includes:
wherein, when the hook swings, the first shaft portion slides inside the first groove portion while the second shaft portion slides inside the second groove portion to draw a swinging trajectory on an outer side of the first shaft portion, so that the slider is pressed to slide.
The present invention may further provide
the tonneau cover device,
wherein the second shaft portion is disposed further than the first shaft portion in the pull-out direction.
The present invention may further provide
the tonneau cover device,
wherein the hook includes a first supporting portion and a second supporting portion that are capable of abutting on edge portions on both sides of the opening of the case,
wherein, when the tonneau cover is pulled out, the first supporting portion abuts on one of the edge portions on the pull-out direction, and the one of the edge portions functions as a supporting point of the swinging movement of the hook,
wherein, when the tonneau cover is wound in the winding direction, the second supporting portion abuts on the other one of the edge portions on the winding direction, and the other one of the edge portions functions as a supporting point of the swinging movement of the hook, and
wherein a distance between the second supporting portion and the second shaft portion is longer than a distance between the first supporting portion and the second shaft portion.
The present invention may further provide
the tonneau cover device,
wherein the spring presses a position of the slider that overlaps the second groove portion when the slider is seen in the sliding direction.
With the tonneau cover device according to the present invention, the cargo chamber of the vehicle can be covered with the tonneau cover by pulling out the tonneau cover from a winding device against the urging force of the cover-urging mechanism to make the engagement protruding portion of the hook engaged with the locking portion to hold the tonneau cover at the pulled-out position.
The tonneau cover device is capable of easily winding the tonneau cover with simple operation of only pushing in the tonneau cover toward the winding direction, whereby winding workability of the tonneau cover can be improved since when a force larger than the urging force of the cover-urging mechanism is exerted on the engagement protruding portion as the tonneau cover is pushed in toward the winding direction, the hook swings, and while the slider is pushed in toward the direction away from the sidewall by the conversion mechanism, the engagement protruding portion retracts into the case to thereby release the engagement with the locking portion.
Hereinafter, a tonneau cover device according to one embodiment will be described referring to the drawings.
As shown in

Next, the hook 80 will be described with reference to
The first shaft portion 84 inserted into the first groove portion 68 of the slider 60 and the second shaft portion 85 inserted into the second groove portion 70 of the slider 60 protrude from the back surface of the swinging portion 81 (the surface on the side of the slider 60). The first shaft portion 84 is disposed approximately in the center on the back surface of the swinging portion 81, and the second shaft portion 85 is disposed closer to the pull-out direction A of the tonneau cover 15 than the first shaft portion 84.
A retaining protrusion 84a having the shape of a quarter of a circular disk is provided at the distal end of the first shaft portion 84.
The retaining protrusion 84a defines a portion that is engaged with the peripheral edge on the back side of the lower opening of the first groove portion 68 of the slider 60 to retain the hook 80 with respect to a direction vertical to the slider 60 as shown in
The guide shaft portion 86 protrudes from a position on a surface of the swinging portion 81 (the surface on the side of the upper case 50), the position being matched to the first shaft portion 84. The guide shaft portion 86 is inserted into the recess-shaped shaft guide portion 55 of the upper case 50 (see
A first supporting portion 87 and a second supporting portion 88 capable of abutting on the edge portions 32a and 32b on both the sides of the opening 32 of the case 30 protrude from both the sides at the base end of the swinging portion 81. To be specific, the first supporting portion 87 that abuts on the pull-out-side edge portion 32a of the opening 32 is provided on one lateral part on the pull-out direction A of the base end of the swinging portion 81 while the second supporting portion 88 that abuts on the winding-side edge portion 32b of the opening 32 is provided on the other lateral part on the winding direction B of the base end of the swinging portion 81. The outer surfaces of the base ends of the first supporting portion 87 and the second supporting portion 88 have a tapered shape of a given angle, which prevents the first supporting portion 87 and the second supporting portion 88 from interfering with the inner surfaces of the slider housing recess 44 when the hook 80 swings.
L2 is formed longer than L1 as shown in
Next, the relation between the swinging movement of the hook 80 and the sliding movement of the slider 60 will be described.
As shown in
When the tonneau cover 15 is pulled out toward the pull-out direction A in a state where the engagement protruding portion 83 of the hook 80 is engaged with the locking portion 5 as shown in
When the tonneau cover 15 is further pulled out toward the pull-out direction A, the distal end of the engagement protruding portion 83 is pressed by the inner surface of the guide portion 3 of the sidewall 1, the hook 80 further swings in the arrow E direction, and the engagement protruding portion 83 disengages from the locking portion 5 and retracts into the case 30 while the second shaft portion 85 presses the second groove portion 70 to further push the slider 60 in the direction away from the sidewall 1 (see
When the tonneau cover 15 is pushed in toward the winding direction B in a state where the engagement protruding portion 83 of the hook 80 is engaged with the locking portion 5 as shown in
When the tonneau cover 15 is further pushed in toward the winding direction B, the distal end of the engagement protruding portion 83 is pressed by the inner surface of the guide portion 3 of the sidewall 1, the hook 80 further swings in the arrow F direction, and the engagement protruding portion 83 disengages from the locking portion 5 and retracts into the case 30 while the second shaft portion 85 presses the second groove portion 70 to push the slider 60 in the direction away from the sidewall 1 (see
As described above, when the hook 80 swings, the first shaft portion 84 of the hook 80 slides inside the first groove portion 68 of the slider 60 while the second groove portion 70 of the slider 60 is pressed by the second shaft portion 85 of the hook 80, whereby the slider 60 moves away from the sidewall 1 against the urging force of the spring 90 in the present embodiment. To be specific, the first shaft portion 84 and the first groove portion 68 are mainly functioning as supporting the swinging movement of the hook 80 while the second groove portion 85 and the second groove portion 70 are functioning as conveying a pressure force accompanied by the swinging movement of the hook 80 to the slider 60. The plural shaft portions 84 and 85 and the plural groove portions 68 and 70 define the “conversion mechanism” that is configured to convert the sliding movement of the slider 60 toward the sidewall 1 into the swinging movement of the hook 80 in the direction in which the engagement protruding portion 83 protrudes from the opening 32 of the case 30 while converting the sliding movement of the slider 60 in the direction away from the sidewall 1 into the swinging movement of the hook 80 in the direction in which the engagement protruding portion 83 retracts into the case 30.
Thus, the tonneau cover device 10 according to the present embodiment has a configuration that when a force larger than the urging force of the cover-urging mechanism is exerted on the engagement protruding portion 83 by pushing in the tonneau cover 15 toward the winding direction B from the state where the engagement protruding portion 83 of the hook 80 is engaged with the locking portion 5 to hold the tonneau cover 15 at the pulled-out position (see
The tonneau cover device 10 according to the present embodiment has the following configuration in order to maintain the state where the engagement protruding portion 83 of the hook 80 is engaged with the locking portion 5 as shown in
To be specific, the tonneau cover device 10 according to the present embodiment has a configuration that in a case where the hook 80 includes the second supporting portion 88 that abuts on the winding-side edge portion 32b of the opening 32 of the case 30, and the winding-side edge portion 32b functions as a supporting point of the swinging movement of the hook 80 as in the present embodiment, M1>M2 is established, in case of M1 representing rotational moment produced when the hook 80 swings with an urging force F1 by the spring 90 while having the winding-side edge portion 32b as a supporting point of the swinging movement of the hook 80, while M2 representing rotational moment produced when the hook 80 swings with an urging force F2 by the cover-urging mechanism (not illustrated) while having the winding-side edge portion 32b as a supporting point of the swinging movement of the hook 80 as shown in
With this configuration, the engagement protruding portion 83 of the hook 80 is brought into surface contact with the second inner surface 5b of the locking portion 5 (see
The tonneau cover device 10 according to the present embodiment has a configuration that in a case where the hook 80 includes no second supporting portion 88, M1′>M2′ is established, under a condition such that M1′ represents rotational moment produced when the hook 80 swings with an urging force F1 by the spring 90 while having the first shaft portion 84 as a supporting point of the swinging movement of the hook 80, and M2′ represents rotational moment produced when the hook 80 swings with an urging force F2 by the cover-urging mechanism (not illustrated) while having the first shaft portion 84 as a supporting point of the swinging movement of the hook 80 as shown in
As shown in
While the shaft portions are provided on the hook side and the groove portions are provided on the slider sides as the conversion mechanism in the present embodiment, shaft portions may be provided on the slider side and the groove portions may be provided to the hook side as the conversion mechanism. The conversion mechanism need not include shaft portions and groove portions as long as it is capable of converting the swinging movement of a hook into a sliding movement of a slider (e.g., a rack-and-pinion structure).
While two shaft portions are provided to the hook in the present embodiment, one shaft portion may be provided thereto. While the first supporting portion and the second supporting portion are provided to the hook in the present embodiment, no supporting portion may be provided thereto. Even in this case, the engagement protruding portion of the hook is pressed by the inner surface of the locking portion and the inner surface of the guide portion provided to the sidewall accompanied by pull-out and push-in movement of the tonneau cover, so that the hook can be swung, and the slider can be slid accompanied thereby.
Next, the operation and advantageous effect of the tonneau cover device 10 having the above-described configuration will be described.
To be specific, when the cargo chamber of the vehicle needs to be covered, the tonneau cover 15 is to be pulled out from the winding device (not illustrated) against the urging force of the cover-urging mechanism (not illustrated) while the fixing devices 20 are slid and guided by the guide portions 3 of the sidewalls 1. At this time, the engagement protruding portions 83 of the hooks 80 are pressed by the guide portions 3 of the sidewalls 1, whereby the sliders 60 are pushed in toward the direction away from the sidewalls 1 against the urging force of the spring 90. Then, when the tonneau cover 15 is stopped being pulled out at position where the engagement protruding portions 83 of the hooks 80 are matched to given locking portions 5, the sliders 60 are urged by the springs 90 while the second shaft portions 85 are pressed by the second groove portions 70 to push the hooks 80, and the engagement protruding portions 83 protrude from the openings 32 of the cases 30, whereby the second outer surfaces 83b of the engagement protruding portions 83 are engaged with the second inner surfaces 5b of the locking portions 5. Thus, the pulled-out position of the tonneau cover 15 is held to allow the tonneau cover 15 to cover the cargo chamber of the vehicle (see
During the pull-out operation of the tonneau cover 15 described above, the first outer surfaces 83a or the distal ends of the engagement protruding portions 83 are pressed by the first inner surfaces 5a of the locking portions 5 or the inner surfaces of the guide portions 3 of the sidewalls 1, and the hooks 80 swing in the arrow E directions while the first supporting portions 87 swing with the pull-out-side edge portions 32a of the openings 32 as supporting points of the swinging movement. Then, the first shaft portions 84 slide inside the first groove portions 68 in the directions opposite to the protruding directions of the sliders 60 while the second shaft portions 85 slide inside to press the second groove portions 70 with drawing the swinging trajectories S on the outer sides of the first shaft portions 84, and the sliders 60 are pushed in toward the directions away from the sidewalls 1 against the urging forces of the springs 90. As a result, the engagement protruding portions 83 disengage from the locking portions 5 to release the engagement with the locking portions 5, as shown in
The tonneau cover 15 is pushed in toward the winding direction B in order to wind the tonneau cover 15. Then, the second outer surfaces 83b or the distal ends of the engagement protruding portions 83 are pressed by the second inner surfaces 5b of the locking portions 5 or the inner surfaces of the guide portions 3 of the sidewalls 1, and the hooks 80 swing in the arrow F directions while the second supporting portions 88 swing with the winding-side edge portions 32b of the openings 32 as supporting points of the swinging movement. Then, the first shaft portions 84 slide inside the first groove portions 68 in the protruding directions of the sliders 60 while the second shaft portions 85 slide inside to press the second groove portions 70 with drawing the swinging trajectories S on the outer sides of the first shaft portions 84, and the sliders 60 are pushed in toward the directions away from the sidewalls 1 against the urging forces of the springs 90. As a result, the engagement protruding portions 83 disengage from the locking portions 5 to release the engagement with the locking portions 5, as shown in
As described above, in the tonneau cover device 10 according to the present embodiment, when a force larger than the urging force of the cover-urging mechanism is exerted on the engagement protruding portions 83 when the tonneau cover 15 is pushed in toward the winding direction B, and the engagement protruding portions 83 of the hooks 80 are pressed by the inner surfaces of the locking portions 5 or the inner surfaces of the guide portions 3 of the sidewalls 1, the hooks 80 swing, and while the sliders 60 are pushed in toward the directions away from the sidewalls 1 by the conversion mechanism including the plural shaft portions 84 and 85 and the groove portions 68 and 70, the engagement protruding portions 83 retract into the cases 30 to thereby release the engagement with the locking portions 5 (see
The tonneau cover device 10 according to the present embodiment has the configuration as described above. It is assumed that the sliding amounts of the sliders 60 in the directions away from the sidewalls 1 when the tonneau cover 15 is pushed in toward the winding direction B from the state where the pulled-out position of the tonneau cover 15 is held to release the engaged engagement protruding portions 83 and locking portions 5 (see
The tonneau cover device 10 according to the present embodiment includes the conversion mechanism configured to convert the swinging movement of the hooks 80 into the sliding movement of the sliders 60 can have a relatively simple structure including the shaft portions of the first shaft portions 84 and the second shaft portions 85 and the groove portions of the first groove portions 68 and the second groove portions 70. When the hooks 80 swing, the first shaft portions 84 slide inside the first groove portions 68 while the second shaft portions 85 slide inside the second groove portions 70 to press the sliders 60 with drawing the swinging trajectories S on the outer sides of the first shaft portions 84, and the sliders 60 are pushed in toward the directions away from the sidewalls 1 (see
The tonneau cover device 10 according to the present embodiment has the configuration that the second shaft portions 85 provided to the hooks 80 are disposed closer to the pull-out direction A of the tonneau cover 15 than the first shaft portions 84 as shown in
The tonneau cover device 10 according to the present embodiment has the configuration that the hooks 80 include the first supporting portions 87 and the second supporting portions 88 that are capable of abutting on the edge portions on both sides of the openings 32 of the cases 30, and the first supporting portions 87 abut on the pull-out-side edge portions 32a of the openings 32 with the pull-out-side edge portions 32a as supporting points of the swinging movement of the hooks 80 when pulling out the tonneau cover 15 while the second supporting portions 88 abut on the winding-side edge portions 32b of the openings 32 with the winding-side edge portions 32b as supporting points of the swinging movement of the hooks 80 when winding the tonneau cover 15. Thus, when the tonneau cover 15 is pulled out or pushed in a state where the engagement protruding portions 83 of the hooks 80 are engaged with the given locking portions 5, the hooks 80 swing via the first supporting portions 87 and the second supporting portions 88 to push the sliders 60 in, whereby the engaged engagement protruding portions 83 and locking portions 5 can be released. At this time, the distance L2 between the second supporting portion 88 and the second shaft portion 85 is formed longer than the distance L1 between the first supporting portion 87 and the second shaft portion 85 as shown in
In the present embodiment, the springs 90 are provided to press the positions of the sliders 60 that overlap the second groove portions 70 provided to the sliders 60 when the sliders 60 are seen in the sliding directions C as shown in
The present invention is not limited to the embodiment described above, and that it is also possible to add a variety of modifications to the embodiment. Such embodiments will also fall within the scope of the present invention.
