Description

  The present invention relates to a tonneau cover structure in which a luggage portion extending from a cover take-in device arranged behind a seat of an automobile to a rear opening / closing door is covered with a tonneau cover.

  Conventionally, in a hatchback type car equipped with a rear opening / closing door (tailgate), there is no luggage compartment (such as a trunk) independent of the passenger compartment, and the tonneau that extends from the back of the rear seat (the last row of seats) to the rear opening / closing door Is generally used as a luggage part (loading part). In this case, since the luggage portion can be seen from the outside of the vehicle through the window of the rear opening / closing door, the tonneau cover is developed / stored on the luggage portion as required by the passenger so that the luggage portion can be visually shielded from the outside of the vehicle.

  A general automobile tonneau cover device (structure) winds and stores a flexible cover material such as leather urged in a winding direction in a winding device disposed behind a rear seat of the vehicle, When the tonneau cover is deployed, the cover material is pulled out in the direction of the rear opening / closing door against the biasing force, and the top of the cover material is locked to the engaging portion provided in the vicinity of the rear opening / closing door to cover the luggage portion. The state can be maintained. Of course, when there is no luggage in the luggage portion or when loading a high-weight luggage, the cover material can be taken up and stored in the take-up device, and the upper portion of the luggage portion can be opened widely. In this case, since the cover material is urged in the winding direction of the winding device in advance, the cover material is naturally wound and stored in the winding device when the user unlocks the front end of the cover material. .

In addition, an engaging element that protrudes on both sides from the front end of the cover member may be provided so that it can be engaged with the engaging part provided on the side wall of the luggage part. In a more advanced configuration, there is also a proposal for a tonneau cover device that can provide a smoother pull-out and winding operation by providing a slide rail of an engagement element on the side wall of the luggage portion, and the engagement element is guided by the slide rail and stably slides. There is (for example, Patent Document 1).
Special table 2001-505158

  Since the cover material of the conventional tonneau cover device described above is always urged so as to be wound into the winding device, the cover material is released when the engagement between the engagement member of the cover material and both side walls of the luggage portion is released. The cover material is automatically wound into the winder while leaving only the grip board at the tip outside the winder.

  By the way, in recent hatchback type automobiles, there is a tendency that a luggage portion having a long depth is preferred, and there are many vehicles having a long distance from the opening of the rear opening / closing door to the winding device of the tonneau cover. In this case, once the engagement is released as described above and the cover material is completely wound up in the winding device, it is difficult to reach the handle board from the opening of the rear opening / closing door, and it is inconvenient to pull out the tonneau cover. There is a problem of being.

  As a technique to deal with such a problem, as shown in FIG. 11, a blind seat that can reciprocate between a closed position and an open position is closed to cover the luggage compartment when the tailgate is closed, and the tailgate. It has a guide groove that can move between the intermediate position that allows access to the luggage compartment when the door is opened, and the pulling rod is inside the vehicle body so that the blind seat is automatically in the intermediate position. 2. Description of the Related Art A roller blind that is configured so that it can be moved to a simple handle is known (for example, Patent Document 1).

  However, in the tonneau cover structure of the type disclosed in Patent Document 1, if the blind seat is left in the intermediate position (half-opened state) and the forgetting to return it to the closed position (fully closed state) and the rear opening / closing door is closed, the appearance is deteriorated. Not only does it interfere with the rear view. In particular, as shown in FIG. 11, when the engaging member can be slid obliquely upward with the guide groove directed obliquely upward, the luggage portion can be seen from the window of the rear opening / closing door of the vehicle when the cover material is opened obliquely upward, There was a problem that the appearance and the rear view were extremely deteriorated. In addition, in order to return the cover material that was forgotten to close with this type of tonneau cover structure, it is necessary to open the rear door again, return the cover material that was forgotten to close to the fully closed position, and close the rear door again. It was very troublesome for the person.

  The present invention has been made in view of the above problems, and provides a tonneau cover structure that can automatically close a tonneau cover when the rear opening / closing door is closed even if the tonneau cover is in an intermediate position. .

In order to solve the above problems, a tonneau cover structure of the present invention includes a cover take-in device disposed behind a seat of an automobile, and the cover take-in device while being urged in the take-in direction by the cover take-in device. A tonneau cover structure that covers the luggage portion between the cover take-in device and the rear opening / closing door by pulling out the cover material, and the tip of the cover material in the pull-out direction An engaging portion provided on the side, a slide rail provided on a side wall forming the luggage portion and slidably engaging the engaging portion, and the engaging portion is urged toward the rear opening / closing door. And an urging member that moves the cover material to a position that covers the luggage portion.
In the tonneau cover structure configured as described above, the engaging portion that is slidably engaged with the slide rail is urged to the rear opening / closing door side by the urging member, and the cover material is in a state other than the state in which the cover material covers the luggage portion. When the support of the cover material is removed in this state (for example, the hand is released), the cover material automatically covers the luggage portion. That is, after the user sets the cover material not to cover the luggage portion when loading / unloading the luggage, the cover material automatically covers the luggage portion even if the cover material does not cover the luggage portion.

  The urging member operates in a direction-selective manner with respect to the engaging portion, and operates to mechanically urge the engaging portion that slides along the slide rail toward the rear opening / closing door. Here, urging toward the rear opening / closing door means that the stress component of the urging force includes a stress component in the rear opening / closing door direction (rear direction of the vehicle), and does not include the stress component in the seat direction (front of the vehicle). . That is, the total stress component of the urging force does not have to be in the rear opening / closing door direction. Further, in the case of an automobile in which the lower part of the rear opening / closing door protrudes outward from the upper part, it may be urged from above to below substantially parallel to the rear opening / closing door surface. Moreover, even if it is the same rear opening / closing door, it may be biased toward the rear opening / closing door portion more rearward of the vehicle. The urging member only needs to be able to urge the engaging portion toward the seat, and may urge the engaging portion directly, or between the engaging portion and the urging member. The member may be in contact with another member while the member is interposed to indirectly bias the engaging portion. The term “mechanically” means that it does not move electrically. For example, it means an elastic member such as a spring or rubber, a weight member such as a weight, or the like.

  Further, the tonneau cover structure of the present invention includes a cover take-in device arranged behind the seat of an automobile, and a cover that can be moved in and out of the cover take-in device while being urged in the take-in direction by the cover take-in device. And a tonneau cover structure that covers the luggage portion by pulling out the cover material, and is provided on an engagement portion provided at a distal end portion of the cover material in a pull-out direction and on a side wall that forms the luggage portion. A slide rail that slidably engages the engaging portion, the slide rail extending in the front-rear direction of the vehicle, and a first rail that extends continuously from the rear door side of the first rail. A locking portion for locking the engaging portion is formed at the connecting portion of the first rail and the second rail, and the angle of the second rail with respect to the first rail is: Above first An engaging portion which moves in engagement with the said second rail may be configured to be formed at an angle to move toward the locking portion relative.

  In the tonneau cover structure configured as described above, the engaging portion is slidably engaged with the slide rail configured by the first rail and the second rail, and the second rail is engaged with the first rail. The formed angle is an angle at which the engaging portion moves toward the locking portion when the engaging portion is engaged with the second rail. That is, the engaging portion that engages with the second rail receives stress that moves toward the locking portion. This stress may be the weight of the tonneau cover or the engaging portion, or may be a stress component generated by the take-in biasing force of the cover take-in device, depending on the angle formed by the first rail and the second rail. Thus, any stress may be used as long as it stresses the engaging portion in the direction of the locking portion. Moreover, when receiving stress by the stress component generated by the take-in biasing force of the cover take-in device, it is preferable that an obtuse angle is formed between the first rail and the second rail.

  The seat means the last row of seats arranged in the automobile, and at least a part of the space located between the seat and the rear opening / closing door is used as the luggage portion. Of course, this space may be used as the luggage portion.

  The cover material is biased in the direction of being taken in by the cover take-in device, and can be taken into and taken out from the cover take-in device. That is, when a force stronger than the loading biasing force is applied in the pull-out direction, the cover material is pulled out, and when the force in the pulling-out direction is weaker than the loading biasing force (or no force in the pulling direction), the cover material is applied to the cover capturing device. It is captured.

  The said cover material front-end | tip part is the edge used as the foremost side when unwinding a cover material from a cover taking-in apparatus. The portion where the engaging portion is provided at the front end portion of the cover material is a position close to the slide rail, and when the slide rail is provided on the side wall of the luggage portion, it is easy to consider providing it on the left and right sides of the front end portion.

  As described above, according to the present invention, the engagement portion that is slidably engaged with the slide rail is provided with a biasing member that biases the engagement portion in a direction against the biasing force of the cover take-in device. The joint portion can be automatically moved to the closed position, and forgetting to close the cover material can be prevented.

  According to the invention of claim 2, by providing the stopper mechanism, the engaging portion is restricted from passing in the direction of being urged by the urging member and is allowed to pass in the direction opposite to the urging direction. Since it is permitted, the movement of the engaging portion to the closed position can be selectively activated.

  According to the third and fourth aspects of the invention, when the rear opening / closing door is closed, the restriction of the passage of the stopper mechanism is released, so that the urging member is operated, and the rear opening / closing door is closed. The cover material can be moved to the closed position in conjunction. That is, while the rear opening / closing door is opened, the tonneau cover is held at a position other than the closed position by the stopper mechanism, and when the rear opening / closing door is closed, the tonneau cover moves to the closed position. Therefore, there is no need for the user to hold the tonneau cover in an appropriate position while opening the rear door, and even if the user forgets to close the tonneau cover and closes the rear door, the user can open the rear door again. There is no need to close the tonneau cover.

  According to the fifth aspect of the present invention, the cover member is automatically moved to the closed position by pushing the engaging portion obliquely downward by providing the biasing member and the stopper mechanism in the obliquely inclined portion of the slide rail. I can do it. Forgetting to close the tonneau cover at the oblique portion is particularly unsatisfactory, but this invention can prevent forgetting to close the tonneau cover at the oblique portion.

  Further, according to the invention of claim 6, since the operating range of the urging member is made to act only at a length not more than half of the side close to the rear opening / closing door of the slide rail, in the half of the side close to the rear opening / closing door, The urging member is urged toward the rear opening / closing door, and the half of the side far from the rear opening / closing door is urged in the taking-in direction by the cover take-in device. Therefore, the user can selectively use a closed state (a state where the entire luggage portion is covered) and a fully open state (a state where the cover capturing device is fully covered and the luggage portion is not covered). Become. Further, the urging distance of the urging member is shortened, the burden on the urging member is reduced, and the components of the urging member can be reduced in size.

  According to the invention of claim 7, by applying the urging force of the urging member with a spring having a strength greater than the winding force of the cover take-in device, only mechanical means are used without using an electric motor or the like. Thus, the tonneau cover structure of the present invention can be configured.

  Further, according to the inventions of claims 8 and 9, since the cover material is taken up on the take-up shaft of the cover take-in device, the cover material can be taken in and out while reducing the space required for the cover take-in device. It can be smooth. Further, since the sheet surface of the cover material is not easily wrinkled, the aesthetic appearance of the cover material is not impaired.

  Needless to say, in a more specific configuration as in claim 10, the same effects as those of the inventions of claims 1 to 7 described above can be obtained.

  According to the invention of claim 11, the two rails are connected to form a slide rail, and the engaging portion moves in the direction of the locking portion in the second rail, so that it can slide on the slide rail. The engaging portion engaged can be automatically moved to the closed position, and forgetting to close the cover material can be prevented.

Hereinafter, preferred embodiments of the present invention will be described in the following order.

(2) Action and effect of tonneau cover structure:
(3) Modification:
(4) Summary:

(1) Tonneau cover structure:
FIG. 1 is a perspective view showing a main part of a hatchback type automobile 100 employing a tonneau cover structure according to an embodiment of the present invention, FIG. 2 is a perspective view of a tonneau cover and a winding device, and FIG. FIG. 4 is a perspective view showing the inside of the side wall of the luggage portion when the rear opening / closing door is closed, and FIG. 5 is a view for explaining the stopper mechanism. In each figure, the rear opening / closing door and the like are omitted for convenience of explanation. In each drawing, the right half of the luggage portion 10 that is symmetrical is shown, and the right half member will be described in the following description, but the left half also has a member symmetrical to the right half.

  As shown in FIG. 1, in the hatchback type automobile, the space behind the rear opening / closing door opening 12 and the rear seat (the last row of seats) 14 is used as a luggage portion (toner portion) for loading luggage. In the present embodiment, the luggage portion 10 is a space defined by an automobile interior floor (floor surface) 10a, left and right sidewalls 10b in the automobile, and front and rear by a winding device 16 and a rear opening / closing door. The luggage unit 10 is provided with a winding device 16 behind the rear seat 14 so that the luggage loaded by deploying a tonneau cover at a midway height above the floor surface 10a can be visually shielded from the outside of the vehicle or from the seat side. Yes.

  The tonneau cover structure generally includes a cover member 20a, a winding device 16, and slide rails 31 and 32 for guiding the cover member 20a. The winding device 16 is disposed behind the rear seat 14, and a flexible cover member 20a such as leather urged in the winding direction is wound around the case 16a. In the present embodiment, the winding device 16 corresponds to a cover taking-in device. Of course, as the cover taking-in device, a method of taking in / drawing out while being folded in a bellows shape is also conceivable. In this case, it is urged by an elastic member such as a spring in the folding direction, or the cover itself is formed of an elastic body such as rubber.

  When the tonneau cover is necessary, the cover member 20a is pulled out from the narrow opening 16b of the case against the urging force, and the engaging elements 20d protruding on both sides of the grip board 20b at the tip of the cover member 20a are engaged with the locking portions on the side wall. The state which latches on 31a and covers the luggage part 10 top is maintained (use condition). On the other hand, when there is no luggage in the luggage portion 10 or when loading / unloading the luggage portion 10, the engagement member 20d and the locking portion 31a are disengaged, and the cover member 20a is wound into the winding device 16 so that the luggage The part 10 is opened (stored state). That is, the user can selectively use the use state and the storage state. In this invention, it has two forms of the intermediate state which maintains the cover material 20a in the intermediate | middle position and the fully-closed state which covers the whole luggage portion as a form of use state.

  The winding device 16 includes a case 16a that is long in the vehicle width direction, and a winding shaft 16c that is pivotally supported in the case 16a so as to be axially rotatable while matching the axial direction with the longitudinal direction of the case 16a. And an urging means for urging 16c in the axial rotation direction. As this urging means, a device that urges the rotating force to the winding shaft such as a torsion coil spring can be considered. The case 16a is formed by extrusion molding of an aluminum steel material or bending of a steel plate, and the case 16a is attached with the case 16a having a short-side cross section (front / rear / top / bottom cross-section relative to an automobile) that is circular or rectangular and having a longitudinal length. The distance approximately coincides with the distance between the side walls of the luggage portion 10. Further, a narrow slit-like opening 16b is formed substantially parallel to the axial direction of the winding shaft 16c on the vehicle rear side (the luggage portion 10 side) of the case 16a, and the cover member 20a passes through this opening 16b and the winding device 16 is formed. Go in and out.

  As shown in FIG. 2, cap materials 17 that cover both ends of the case 16 a are fitted on both sides in the longitudinal direction. The cap material 17 is formed into a cylindrical shape by resin molding such as resin injection molding, and one end is opened to accept the case 16a. Both ends of the case into which the cap material 17 is fitted are fixedly attached by being fitted into a concave groove formed in the side wall 10b. At this time, the cap material 17 is interposed between the side wall 10b and the case 16a, and functions as a cushioning material for the case 16a and the side wall 10b to protect both. The cap member 17 includes a support portion inside the cylinder, and pivotally supports both ends of the winding shaft 16c of the cover member 20a so as to be rotatable.

  The winding shaft 16c is an elongated shaft disposed along the longitudinal direction of the case 16a so as to be located in the center in the short-side cross section of the case 16a. Formed with material. Further, the winding shaft 16c is pivotally supported by the cap member 17 on both sides, and is coupled to the torsion coil spring and is urged so as to generate a cover member 20a winding force by the torsion coil spring. One end of the torsion coil spring is fixed to the winding shaft 16 c, and the other end is fixed to at least one of the case 16 a and the cap material 17. Further, one end edge of the cover material 20a is adhered to the winding shaft 16c, and when the force in the direction of pulling out the cover material 20a disappears, the cover material 20a is automatically wound and stored on the winding shaft 16c. Thus, the state in which the cover member 20a is wound and stored in the winding device 16 corresponds to the storage state.

  The cover material 20a wound around the take-up shaft 16c is formed of an opaque soft leather material having a light shielding property, and can have a thickness of 0.5 to 1.0 mm, for example. From the viewpoint of allowing the luggage portion 10 to cover the entire width direction of the luggage portion 10 so that it can enter and exit from the opening, the width of the cover material 20a is close to the distance between the side walls of the luggage portion 10 and slightly shorter than the lateral width of the opening 16b of the case 16a. It is preferable to form. Further, from the viewpoint of preventing the slack of the cover member 20a while covering the depth direction of the luggage portion 10 as a whole, the length (depth) of the cover member 20a in the pulling direction is formed to be the same as or slightly longer than the depth of the luggage portion 10. Is preferred.

  A thin handle board 20b (thickness of 5 to 10 mm) is provided at the front end of the cover material 20a (front side in the pull-out direction), and serves as a pull when the cover material 20a is pulled out from the case 16a. Also prevents deflection in the vehicle width direction. If the thickness of the handle board 20b is slightly larger than the height (slit width) of the opening 16b of the case 16a, the cover material 20a is not completely wound into the case 16a during winding, and the cover material 20a can be easily redrawn. It becomes. In addition, it is preferable that the handle board 20b is formed so as to fill a gap between the front end of the rectangular cover member 20a and the curved rear opening / closing door so that the entire luggage portion 10 can be covered. In addition, it is preferable to provide a grip for operation at the center of the handle board because the handle becomes a handle when the tonneau cover is pulled out, and the pulling operation becomes easy. Hereinafter, the cover material 20a and the handle board 20b will be described together as the tonneau cover 20 unless specifically indicated.

  On both sides of the handle board 20b in the vehicle width direction, engaging members 20d that engage with the slide rails 31 and 32 are provided by being fixed to the handle board 20b by screwing or fitting. The shape of the protruding portion of the engagement element 20d is preferably a cylinder or a prismatic shape with rounded corners. For example, the diameter is 5 to 10 mm, and the length is 10 to 20 mm protruding from both sides of the handle board in the vehicle width direction. The engagement element 20d is preferably formed of a resin material such as a polyamide resin or an ABS resin from the viewpoints of slipperiness with the slide rails 31 and 32 and wear resistance. In this embodiment, the engaging element 20d corresponds to the engaging portion.

  The side wall 10b of the luggage portion 10 is a surface layer provided on the side of the luggage portion 10 of the vehicle body for imparting designability as an interior material and protecting the luggage, and a nonwoven fabric in which a binder is mixed with fibers can be used. The side wall 10b is formed and laid in a shape along the panel of the vehicle body, and the general surface covers the panel of the vehicle body.

  Rail garnishes are disposed on the left and right side walls 10b at substantially the same height as the winding device 16, and slide rails are formed on the rail garnishes. The rail garnish is formed by injection molding of a resin such as polypropylene or polyethylene terephthalate. The rail garnish has a length close to the depth of the luggage portion 10 in order to guide the tonneau cover 20 between the winding device 16 and the rear opening / closing door. Moreover, when the vehicle height direction is 20 to 50 mm and the plate thickness in the vehicle width direction is 2 to 4 mm, rigidity for supporting the tonneau cover 20 with the slide rail is secured, which is preferable.

  The slide rails 31 and 32 are formed on the side wall 10b from the vicinity of the winding device 16 in the vicinity of the rear opening / closing door, and from the vicinity of the rear opening / closing door of the horizontal portion 31 to the winding device 16 in an obliquely upward direction. The inclined portion 32 is formed. The slide rail is formed by forming a concave groove or a notch shape corresponding to the slide rail at the time of forming a garnish (rail garnish or garnish along the rear opening / closing door described later), or fastening a separate slide rail member to the garnish.

  The horizontal portion 31 is linearly formed along substantially the middle height of the rail garnish so as to slidably receive the engaging element 20d of the handle board 20b. The length of the horizontal portion 31 is a length close to the depth of the luggage portion 10 and is formed slightly on the rail garnish because it is formed on the rail garnish. The height (groove width) of the horizontal portion 31 is slightly larger than the diameter (5 to 10 mm) of the engaging element 20d so that the engaging element 20d can be received in the groove and slidable.

  The inclined portion 32 may be formed integrally on the rail garnish by extending the horizontal portion 31, or may be formed on the garnish along the rear opening / closing door which is separate from the rail garnish. The height (groove width) of the groove of the inclined portion 32 is the same as that of the horizontal portion 31 and is formed to an arbitrary height along the opening 12 of the rear opening / closing door. Since the inclined portion 32 is formed along the inclination of the opening 12 of the rear opening / closing door, the angle (inclination) formed by the inclined portion 32 and the horizontal portion 31 is that of the opening 12 of the rear opening / closing door of each vehicle. Although it differs depending on the inclination, it is generally in the range of 10 to 60 degrees. Of course, depending on the shape of the opening 12 of the rear opening / closing door, the inclined portion 32 and the horizontal portion 31 may be formed at an angle of 60 degrees or more (for example, a right angle or an obtuse angle).

  The slide rail is provided with an engaging portion 31a for engaging and engaging the engaging element 20d against the winding attachment force of the winding device 16. One locking portion 31a is provided in the vicinity of the edge on the side close to the rear opening / closing door of the horizontal portion, and is perpendicular to the groove shape of the slide rails 31 and 32 (the groove width direction, downward in FIG. 2). It is provided as a dent that widens the groove shape on the side surface of the groove so that the engaging element 20d can be engaged. After the user pulls out the tonneau cover 20 toward the rear opening / closing door (against the winding urging force), the user engages the engaging member 20d with the locking portion 31a and maintains it in the pulled out state. The state in which the engaging member 20d is engaged with the engaging portion 31a and the tonneau cover 20 covers the luggage portion 10 above corresponds to the fully closed state.

  Further, if the curve near the winding device 16 in the curve formed at the connecting portion between the inclined portion and the horizontal portion is an x curve, the locking surface on which the locking portion 31a locks the engaging portion 20d is , It is formed at a position closer to the winding device 16 than the x curve. That is, the engaging portion 20d that has been urged by the urging member 33 to slide the oblique portion and moved from the oblique portion to the horizontal portion reaches the engagement surface of the engagement portion 31a from the x curve. It moves downward from the horizontal part and is locked to the locking part 31a.

  The locking portion 31a may be formed as a protrusion on the x curve. That is, as shown in FIG. 10, the connecting portion between the inclined portion and the horizontal portion is wider than the width of the engaging portion 20 d or the abutting portion 33 b, and the protrusion substantially perpendicular to the sliding direction of the inclined portion is x Provide on the curve. This protrusion is formed in a position and shape for receiving the engaging portion 20d that slides from the oblique portion toward the connecting portion. Then, by moving the engaging portion so as to avoid the protrusion, the engaging portion can be moved to the horizontal portion. More specifically, in order to move the engaging portion from the oblique portion to the horizontal portion, after moving the engaging portion 20d substantially perpendicular to the sliding direction of the oblique portion, the outside of the curve of the connecting portion Move to the horizontal part along. The movement from the horizontal part to the oblique part is the opposite.

  The inclined portion 32 is used when the tonneau cover 20 pulled out from the winding device 16 toward the rear opening / closing door is to be lifted obliquely upward. For example, when the luggage is not so large when the luggage is loaded, sliding the tonneau cover 20 through the horizontal part and completely winding the tonneau cover 16 on the take-up device 16 increases the distance from the rear opening / closing door, which makes the tonneau cover 20 easier for the user. The drawer becomes troublesome. At this time, if the tonneau cover 20 is lifted obliquely upward, the tonneau cover 20 can be easily pulled out because the distance from the user is short while securing a space for loading and unloading luggage. Further, raising the tonneau cover 20 obliquely upward is also preferable when opening and closing only the glass hatch of the rear opening / closing door to load / unload luggage to / from the luggage portion 10. In the present embodiment, the state in which the tonneau cover 20 is raised obliquely upward of the inclined portion 32 corresponds to the intermediate state in the present embodiment.

  The slide rail of the present invention includes a biasing member 33 that biases the engaging element 20d in a direction that resists the winding attachment biasing force of the winding device 16. The urging member 33 has a stress component in a direction opposite to the winding attachment urging force provided in the winding device 16 of the cover member 20a, and acts on the engaging member 20d to counter the urging force of the winding device 16 and tonneau cover. It is urged in the direction to move 20 to the rear opening / closing door side.

  However, if the urging member 33 is always operating, even if the tonneau cover 20 is lifted obliquely above the inclined portion 32, the tonneau cover 20 is closed by sliding obliquely downward due to the urging force of the urging member 33. The user needs to support the tonneau cover 20. Therefore, it is more preferable to provide a stopper mechanism 34 that restricts the operation of either or a combination of the engaging member 20d and the urging member 33.

  The stopper mechanism 34 allows at least one of the engaging member 20d and the biasing member 33 to pass in one direction but not in the other direction. For example, it is possible to move from the rear opening / closing door side to the rear seat 14 side and to restrict passage from the rear seat 14 side to the rear opening / closing door side. That is, the stopper mechanism 34 temporarily stops at least one of the passage of the engaging element 20d and the operation of the urging member 33.

The main body 34a of the stopper mechanism has a shape that is long in a direction parallel to the inclined portion 32 and short in a direction perpendicular to the inclined portion 32 (for example, an ellipse or a rectangle), and is close to the inclined portion 32. Arranged. As a result, the rotation angle when the contact portion 34a2 rotates from the position A where the contact portion 34a2 contacts the engagement element 20d to the position B where the contact portion 34a2 does not contact the engagement element 20d becomes small, and the space required for the stopper mechanism 34 can be reduced. The tip of the abutting portion 34a2 is formed on a smooth outwardly convex curve with no corners, and a smooth transition is possible when rotating from the position A to the position B while abutting the engaging element 20d. .
Specifically, as shown in FIG. 5, a compression coil spring 33 a having a contact portion 33 b at the tip is disposed obliquely above the engaging element 20 d of the inclined portion 32. The contact portion 33b is pressed obliquely downward by the compression coil spring 33a, contacts the engagement member 20d, and moves the engagement portion 20d inclined portion 32 obliquely downward against the winding mounting force of the winding device 16. In this embodiment, the compression coil spring 33a provided with the contact portion 33b at the tip constitutes the urging member 33. The biasing force of the compression coil spring 33a is preferably 105 to 200% against the force generated from the winding force of the cover material 20a. That is, if the urging force of the compression coil spring 33a is too weak compared with the force generated from the winding force of the cover member 20a, the pressing operation of the engaging member 20d becomes incomplete, and if it is too strong, the operation becomes too sudden. This is because it is difficult to generate a large noise.

  An insulator type stopper mechanism 34 is provided in the vicinity of the inclined portion 32. The stopper mechanism 34 includes a main body 34a having a rotation support shaft 34a1 and a rotation angle limiting hole 35 provided in the vehicle body for limiting the rotation range. In addition to the support shaft 34 a 1, the main body 34 a protrudes to the inclined portion 32, thereby contacting the engaging element 20 d and restricting the downward movement of the engaging element 20 d. An exposed portion 34a3 that extends in the direction and exposes a part of the vehicle in contact with the rear opening / closing door of the vehicle body, and a protrusion 34a4 that engages with the rotation angle limiting hole 35 to limit the range of rotation of the main body 34a. Is done.

  In providing such a stopper mechanism 34, the contact position of the opening 12 with the back door and the inclined portion 32 are at least several centimeters apart. In other words, there are the following methods and problems for causing the contact portion 34a2 on the opposite side of the exposed portion 34a3 from projecting to the engaging element 20d movement path while exposing the exposed portion 34a3 to the contact position with the back door. . Increasing the angle formed by the long axis of the main body 34a and the inclined portion 32 requires a strong spring to receive the urging force of the urging member or requires a large force to push the exposed portion. There is. As a solution to this problem, it is conceivable to increase the length of the main body or increase the size of the main body, but a new problem of increasing the space required for the stopper mechanism occurs.

  Therefore, more specifically, as shown in FIG. 5, the main body 34a of the stopper mechanism 34 is a crank-shaped member, and a pivotal support shaft 34a1 is provided at a portion connecting the parts parallel to each other. The support shaft 34a1 is provided at such a position that the crank-shaped portion draws one substantially flat surface by rotation. In the portions parallel to each other of the crank-shaped member, a portion extending in the left direction at the lower left of the support shaft 34a1 is a contact portion, and a portion extending in the right direction at the upper right of the support shaft is an exposed portion.

  Thus, when the shape of the main body is a crank shape, the abutting portion abuts the abutting portion substantially parallel to the urging direction of the urging member. The biasing force has a small component for rotating the main body, and the biasing force of the biasing means for biasing so that the contact portion is in the slide path of the engaging element may be small. In other words, the structure that solves the above-mentioned problems can be achieved by efficiently receiving the urging force of the urging member while preventing the length of the main body and the body size from being increased, and reducing the force to push the exposed portion to release the stopper mechanism. Can be provided.

  The range of rotation limited by the rotation angle limiting hole 35 and the protrusion 34a4 is from the position (position A) where the contact portion 34a2 contacts the engagement member 20d and restricts the passage of the engagement member 20d in the inclined portion 32. This is a range up to a position (position B) where the contact portion 34a2 rotates around the support shaft 34a1 and does not interfere with the engaging element 20d. And it is urged | biased by the spring not shown in the direction (counterclockwise direction in FIG. 3) which rotates to the position A from the position B. FIG. Of course, it may be biased by a weight instead of a spring. In the present embodiment, the state where the contact portion 34a2 of the stopper mechanism 34 is at the position A corresponds to the first state, and the state where the contact portion 34a2 of the stopper mechanism 34 is at the position B corresponds to the second state.

  As described above, the stopper mechanism 34 restricts the diagonally downward passage when the engaging element 20d is obliquely above the abutting part 34a2 in the inclined portion 32, and the engaging element 20d is obliquely upward from the obliquely downward portion 32. When moving to, the operation is allowed. The exposed portion 34a3 is pushed into the vehicle body by the rear opening / closing door when the rear opening / closing door is closed. Then, the contact portion 34a2 rotates from the position A to the position B around the support shaft 34a1 to release the restriction of the passage of the engaging element 20d, the compression coil spring 33a is operated, and the contact portion 33b moves obliquely downward. .

  In this embodiment, since the compression coil spring 33a acting via the contact portion 33b is employed as the urging member 33, the biasing member 33 is disposed above the engaging portion 20d of the inclined portion. However, as long as the slide rail can slide. Various things can be adopted. For example, a tension coil spring is disposed below the inclined portion engaging element 20d to urge the abutting portion 33b in a pulling direction, and a spiral spring is disposed below the inclined portion engaging element 20d to be applied by a wire or the like. It is conceivable that the contact portion 33b is urged in the pulling direction, and the inclined portion 32 is urged by a weight or the like that pushes (pulls) the engaging member in an oblique direction. Further, the urging member 33 is not limited to a compression coil spring, a tension coil spring, and a spiral spring, and other forms of elastic members such as springs and rubber are used, or the engaging element 20d is urged downward by a weight or the like. It is also possible to use a weight member. Further, the compression coil spring 33a may directly urge the engaging element 20d without using the contact portion 33b.

  The stopper mechanism 34 may act on the urging member 33 via the engaging element 20d or may directly act on the urging member 33. As the stopper mechanism 34, a mechanically operated one is suitable, but a hydraulically acting one or an electrically acting one may be used. Note that the stopper mechanism 34 in FIG. 4 is actually hidden behind the interior material on the side wall.

(2) Action and effect of tonneau cover structure:
The mode (function) when the tonneau cover structure of the present invention is actually used will be described below.
When there is no luggage in the luggage portion 10, the cover member 20a is initially wound around the winding shaft 16c in the case 16a behind the rear seat 14, so that the upper portion of the luggage portion 10 is opened (storage). Status). On the other hand, when there is a load in the luggage portion 10, the cover member 20a is pulled out from the case 16a, and the engaging element 20d is locked to the locking portion 31a (fully closed state).

  Now, with the luggage portion 10 having a load and the cover member 20a being pulled out from the case 16a and covering the upper portion of the luggage portion 10, the user loads some more load on the luggage portion 10 (or a part thereof). When lowering), the rear opening door is opened in order to newly load the luggage portion 10. At this time, if the rear opening / closing door is provided with an electric hatchback mechanism, the user need not touch the rear opening / closing door.

  When the rear opening / closing door is opened, if the tonneau cover 20 covers the upper portion of the luggage portion 10 next, it is difficult to load the luggage, so this is opened. At this time, when the newly loaded luggage is large, the entire cover material 20a is wound around the case and the upper portion of the luggage portion 10 is opened to load the luggage. When the newly loaded luggage is small, the entire cover material 20a is loaded. If it winds up in a case, when drawing out the cover material 20a next, there will be troublesome to reach to the back of the luggage. Therefore, consider moving the grip board (engagement member 20d) to a position where it is easy to grip the grip board (grip part).

  Therefore, the engagement member 20d is moved in the direction of the inclined portion 32 of the slide rail to open the cover member 20a obliquely upward (intermediate state). Then, it is not necessary for the handle board to go to the back of the luggage portion 10, and it is possible to make the baggage loading space relatively wide. The engaging element 20d jumps up the stopper mechanism 34 and climbs over the stopper mechanism 34 when it moves up the slide rail of the inclined portion 32 while abutting the abutting part 33b provided at the tip of the compression coil spring 33a. When the inclination of the inclined portion 32 is high (when the angle formed by the inclined portion and the horizontal portion is smaller than 90 °), the component of the winding device 16 in the inclined portion 32 in the winding attachment force is the engagement element. Since it acts on 20d, the force required when lifting the tonneau cover is reduced, and the user can easily lift the tonneau cover.

  Next, the cover board 20b is pulled with the grip board 20b (or the grip part 20c), and the engaging member 20d is engaged with the engaging part 31a of the slide rail to bring the cover part 20a into the fully closed position (fully closed state). . However, if this is forgotten or troublesome because the hands are blocked, the tonneau cover structure of the present invention may close the rear door as it is. That is, when the rear opening / closing door is closed, the exposed portion 34a3 and the rear opening / closing door interfere with each other, and the stopper mechanism 34 rotates counterclockwise around the support shaft 34b, so that the contact between the contact portion 34d and the engaging member 20d is released. The stopper is canceled. Then, the urging member 33 and the engaging member 20d which have been positioned obliquely upward of the stopper mechanism 34 are moved obliquely downward along the inclined portion 32 by the urging force of the compression coil spring 33a to bring the cover member 20a to the fully closed position. Move (fully closed). Therefore, even if the tonneau cover 20 is forgotten to close, the tonneau cover 20 does not remain in the intermediate state.

(3) Modification:
As an intermediate state of the present invention, it may be provided at an intermediate position of the horizontal portion 31 in addition to the state regulated by the stopper mechanism 34 provided at the oblique portion as described above. FIGS. 6 to 9 are views for explaining a mechanism of a modified example of the tonneau cover structure. 6 and 7 correspond to the case where the rear opening / closing door is open, and FIGS. 8 and 9 correspond to the case where the rear opening / closing door is closed. 6 and 8 show the tonneau cover structure from the side, and FIGS. 7 and 9 show the tonneau cover structure from the top. Hereinafter, a modified example of the intermediate state will be described with reference to FIGS. In the following explanation, the right half of the luggage portion will be described as the center, but the left half is assumed to have a member symmetrical to the right half.

  In the present modification, a second engagement portion 31 b is provided at an intermediate position of the horizontal portion 31. The second engaging portion 31b is formed as a dent that widens the groove shape on the groove side surface in the direction perpendicular to the groove shape of the horizontal portion 31 (the width direction of the groove, downward in FIG. 6), and can engage the engaging element 20d. It is what. The intermediate position means the interval from the locking portion 31a to the position where the cover member 20a is accommodated in the winding device 16, and in particular, when the rear opening / closing door is opened, the user's hand is from the outside of the rear opening / closing door. It is preferable that it is within easy reach.

  A parallel groove 40 parallel to the horizontal portion 31 is provided on the rear opening / closing door side from the second engagement portion 31b, and a support groove 41 is formed as a groove extending obliquely upward from the parallel groove 40 to the rear seat side. The parallel groove 40 is continuously formed in parallel with the horizontal portion 31 from a position corresponding to at least the locking portion 31a to a position corresponding to the second engaging portion 31b, and from the position corresponding to the second engaging portion 31b. A support groove 41 is formed obliquely upward on the rear seat 14 side.

  An insulator type stopper mechanism 43 is provided in the vicinity of the intermediate position of the parallel groove 40. The stopper mechanism 43 includes a main body 43a having a rotation support shaft 43a1 and a rotation angle limiting hole 36 provided in the vehicle body for limiting the rotation range. In addition to the support shaft 43a1, the main body 43a protrudes from the horizontal portion 31 so as to contact the engaging element 20d and restrict the movement of the engaging element 20d toward the rear opening / closing door, and the rotation angle limiting hole 36. And a projection 43a3 that engages with and restricts the range of rotation of the main body 43a.

  The range of rotation limited by the rotation angle limiting hole 36 and the protrusion 43a3 is from the position (position C) where the contact portion 43a2 contacts the engagement member 20d and restricts the passage of the engagement member 20d in the horizontal portion 31. This is a range up to a position (position D) where the portion 43a2 rotates around the support shaft 43a1 and does not interfere with the engaging element 20d. And it is urged | biased by the spring which is not shown in the direction (counterclockwise direction in FIG. 5) which rotates to the position C from the position D. FIG. Of course, it may be biased by a weight instead of a spring. The stopper mechanism 43 includes a mechanism that rotates to the position D in conjunction with the closing of the rear opening / closing door. In this modification, the state where the contact portion 43a2 of the stopper mechanism 43 is at the position C corresponds to the first state, and the state where the contact portion 43a2 of the stopper mechanism 43 is at the position D corresponds to the second state.

  Further, the abutting portion 42 a urged in the direction of the rear opening / closing door by the compression coil spring 42 b is disposed so as to be movable along the parallel groove 40. In this modification, the compression coil spring 42b and the abutting portion 42a biased thereby constitute a biasing member 42.

  The contact portion 42a includes an arm 42c that protrudes toward the horizontal portion 31 perpendicular to the parallel groove 40 in the initial state. The arm 42c can rotate on a substantially flat surface formed by the horizontal portion 31 and the parallel groove 40 (the same surface as the paper surface in FIG. 6). Further, it is not possible to rotate from the initial position to the rear seat side (clockwise rotation in FIG. 6), and from the initial state position to the rear opening / closing door side (counterclockwise in FIG. 6). Rotation) is possible. Furthermore, the arm 42c is biased by a spring or the like so as to return to the initial position. The protruding length of the arm 42c with respect to the horizontal portion 31 is not limited as long as the arm 42c cannot pass through the engaging element 20d that passes through the horizontal portion 31. The length which protrudes to the middle of the part 31 may be sufficient.

  That is, when the engaging element 20d abuts from the rear seat side of the arm 42c and pushes the arm 42c toward the rear opening / closing door side, the arm 42c rotates to the rear opening / closing door side, but the engaging element 20d is rearward of the arm 42c. When the arm 42c moves to the opening / closing door and stops contacting the arm 42c, the arm 42c automatically returns to the initial state. Furthermore, when the parallel movement distance between the rear groove 14 side end portion of the support groove 41 and the parallel groove 40 is equal to or longer than the length of the arm 42c, the contact portion 42a reaches the rear seat 14 side end portion of the support groove 41. Since the arm 42c does not protrude to the horizontal portion 31, the movement of the engagement member 20d in the direction of the rear seat 14 is not hindered, and the engagement member 20d moves to the rear seat side end of the horizontal portion 31 by the winding attachment force of the winding device 16. . That is, the cover member 20 a is stored by the winding attachment force of the winding device 16. Of course, the parallel movement distance between the rear groove 14 side end of the support groove 41 and the parallel groove 40 can move the contact portion 42a to a position where at least the arm 42c does not hinder the movement of the engagement element 20d in the direction of the rear seat 14. It suffices that the length is equal to or longer than the length of the arm 42c.

  As described above, the stopper mechanism 43 restricts the movement of the contact portion 43a2 to the rear opening / closing door side when the engaging member 20d is located on the rear seat side of the contact portion 43a2 in the horizontal portion 31. When the lever 20d moves from the rear opening / closing door side to the rear seat side, the operation is allowed. When the rear opening / closing door is closed, the contact portion 43a2 rotates from the position C to the position D around the support shaft 43a1 to release the restriction of the passage of the engaging element 20d, and the urging member 42 is operated to contact the contact portion. 42a moves to the rear opening / closing door side along the parallel groove 40, and accordingly, the engaging element 20d biased by the arm 42c also moves to the rear opening / closing door side and is locked to the locking portion 31a.

  In this modification, the compression coil spring 42b, the contact portion 42a, and the arm 42c correspond to the urging member 42. The urging member 42 can urge the engaging member 20d of the horizontal portion 31 while sliding the parallel groove 40. Various things can be adopted as long as they are appropriate. For example, it is conceivable that the abutting portion 42a is urged in the tension direction with a tension coil spring. The form of the spring is not limited to the compression coil spring or the tension spring, and other forms of springs can be used. It is.

The operation of the tonneau cover structure according to the configuration of the above modification will be described.
When the tonneau cover 20 is fully closed, when the tonneau cover 20 is moved to the intermediate position by pushing the grip 20c of the handle board 20b from the rear opening / closing door side, the urging member 42 of the parallel groove 40 is located on the rear seat 14 rather than the stopper mechanism 43. The contact portion 42a is moved to the side, and the stopper mechanism 43 restricts the movement in the rear opening / closing door direction and stops at the intermediate position (intermediate state of the modification).

  When the intermediate state is desired to be stored, the tonneau cover 20 is further pushed. Then, the contact part 42a connected to the arm 42c moves from the parallel groove 40 to the continuous support groove 41. At this time, since the contact portion 42a moves obliquely upward, the arm 42c also moves upward, so that the arm is positioned above the horizontal portion 31. Therefore, the arm 42c does not restrict the movement of the engagement element 20d in the direction of the winding device 16, and the tonneau cover 20 is wound and stored by the winding force of the winding device 16 (stored state). When the arm 42c and the engaging element 20d do not come into contact with each other, the arm 42c and the contact part 42a return to the position regulated by the stopper mechanism by the urging force of the compression coil spring 42b.

  On the other hand, when the tonneau cover 20 is moved from the winding device 16 side to the rear opening / closing door side, the tonneau cover 20 is first pulled out to the rear opening / closing door side against the winding attachment force. Here, when the engaging element 20d comes into contact with the arm 42c, the urging force in the rotation direction of the arm 42c is also applied to the winding attachment urging force, and the tonneau cover 20 is pulled out to the rear opening / closing door side against both. Then, when the arm 42c rotates counterclockwise and the engagement element 20d moves from the arm 42c to the rear opening / closing door side, only the winding attachment force is applied to the tonneau cover 20 again. When the engaging element 20d is released at a position closer to the rear seat 14 than the locking part 31a, the engaging part 20d is in an intermediate state, and when the engaging element 20d is engaged with the engaging part 31a, the engaging part is fully closed.

  If it is not necessary to automatically close the tonneau cover 20 in conjunction with the closing of the rear opening / closing door when the tonneau cover 20 is in the intermediate state, the parallel grooves 40, the support grooves 41, and the compression coil springs 42b are in contact with each other. The contact portion 42a and the stopper mechanism 43 are not necessarily required. If only the second engagement portion 31b is formed, the tonneau cover 20 can be stopped at an intermediate position.

(4) Summary:
As described above, according to the present invention, the biasing member 33 that biases the engaging member 20d that is slidably engaged with the inclined portion 32, and the passage of the engaging member 20d obliquely downward are restricted and obliquely upward. A stopper mechanism 34 that allows passage is provided, and when the rear opening / closing door is closed, the restriction of passage of the stopper mechanism 34 is released and the tonneau cover 20 is automatically closed. This makes it possible to prevent forgetting to close the tonneau cover 20.

  Further, a biasing member 42 that biases the engaging element 20d that is slidably engaged with the horizontal portion 31, and a passage to the rear opening / closing door side of the biasing member 42 are restricted and a passage to the rear seat side is permitted. A stopper mechanism 43 is provided, and when the rear opening / closing door is closed, the restriction of passage of the stopper mechanism 43 is released in conjunction with the rear opening / closing door so that the tonneau cover 20 is automatically fully closed. This makes it possible to prevent forgetting to close the tonneau cover 20.

  Further, by providing the urging member 33 and the stopper mechanism 34, or the urging member 42 and the stopper mechanism 43, the cover member 20a is engaged with the engagement element 20d at an intermediate position where the cover member 20a is not completely wound into the winding device 16. A storage state in which the cover member 20a is completely wound up, a fully closed state in which the cover portion 20a is completely covered with the cover member 20a, and an intermediate state in which the cover member 20a is locked at an intermediate position between the storage state and the fully closed state. Users can select and use.
