Description

  The present invention relates to a tonneau cover device that shields a luggage compartment of a vehicle.

  Conventionally, in a hatchback type automobile or the like in which the luggage compartment is not separated from the passenger compartment and the luggage compartment is provided at the rear of the rear seat, the cargo placed in the luggage compartment is not visually recognized from the outside. A tonneau cover device is provided near the rear of the rear seat of the chamber.

  In general, the tonneau cover device has a tonneau cover sheet for shielding the entire cargo compartment, a case for storing the tonneau cover sheet, and a rear end of the tonneau cover sheet fixed to each other, and a winding supported rotatably inside the case. And a take-up shaft. A slit-like opening extending in the longitudinal direction is formed on one surface of the case. By rotating and energizing the take-up shaft in the take-up direction, the tonneau cover sheet that has been stretched can be taken up through the opening. A plate-shaped grip board is coupled to the tip of the tonneau cover sheet. The grip board has a grip portion for a user to grip by hand when pulling out the tonneau cover sheet from the case, and a locking hook provided at both ends in the width direction. In addition, since the grip board is larger than the opening, the grip board does not enter the case through the opening but protrudes from the opening even when the tonneau cover sheet is wound by the winding shaft. Become. Therefore, all of the tonneau cover sheet is not wound on the winding shaft.

  In addition, since the back door that forms the rear end of the cargo compartment of an automobile is usually curved toward the rear of the vehicle, the grip board is shaped to correspond to the shape of the back door to cover the entire cargo compartment. It can be set as the structure which can be hidden.

  When using the tonneau cover device, the user grasps the grasping portion provided on the grasping board, pulls out the tonneau cover sheet from the opening of the case against the urging force of the take-up shaft in the take-up direction, The locking hooks at both ends are locked to locking devices provided on the side of the cargo compartment. When the locking hook is locked by the locking device, the tonneau cover sheet maintains the stretched state.

  Since the above-mentioned grip board is generally composed of a molded body such as resin having a certain thickness and a reinforcing plate, the tonneau cover sheet projects from the opening of the case in a state where the tonneau cover sheet is wound around the winding shaft. The grip board hangs down due to its own weight. For this reason, there has been a problem in that abnormal noise is generated by the gripping board interfering with the case or the like due to vibration or the like when the vehicle is traveling.

  An example of a conventional tonneau cover device that solves this problem is disclosed in Patent Document 1. In the tonneau cover device described in Patent Document 1, end caps are provided at both ends in the width direction of the gripping board instead of locking hooks, and engagement holes are provided at both ends in the width direction of the opening of the case. ing. The end cap has a role of engaging with an engaging hole as well as a role of locking with a locking device provided on the side of the cargo compartment. In Patent Document 1, when the tonneau cover sheet is rolled up and stored in the case, the gripping board can be held in a horizontal state by fitting the end cap and the engagement hole, thereby solving the above problem. You can do that. However, in the tonneau cover device described in Patent Document 1, it is necessary to form engagement holes on both side portions in the width direction of the opening of the case, and accordingly, the number of processing steps increases and the cost increases. Was left.

  Another example of the configuration of the conventional tonneau cover device that can solve the problem that has occurred in the tonneau cover device of Patent Document 1 is disclosed in Patent Document 2. In FIG. 6, the schematic of the cross section of another example of the tonneau cover apparatus of a prior art is shown. When the tonneau cover sheet 100 is expanded, a pair of locking tools (locking hooks) 160 for engaging with a locking device provided on the rear side of the cargo compartment (not shown) of the car and maintaining the expanded state, The tonneau cover sheet 100 is provided at both ends in the width direction of the grip board provided at the leading end in the pull-out direction.

  In addition to the first engagement portion (not shown) that engages with the locking device, each of the locking tools 160 has a second engagement portion 110 that engages with the opening 120 of the case 150 where the tonneau cover sheet 100 enters and exits. Are integrally formed. Further, a groove 130 is formed on the upper surface of the second engaging portion 110 so that the upper edge 170 of the case 150 that forms a part of the opening 120 is fitted therein. A stopper 140 that contacts the surface of the case 150 is formed on the lower surface of the second engaging portion 110 so as to protrude below the opening 120. The case 150 is formed so as to be elastically deformable in a direction in which the opening height of the opening 120 (the vertical direction, that is, the width in the vehicle vertical direction) is increased.

  The second engaging part 110 is fitted into the opening part 120 while deforming the opening part 120, so that the upper edge part 170 that forms a part of the opening part 120 of the case 150 and the first engagement part 160. 2 The groove 130 on the upper surface of the engaging portion 110 is engaged. Therefore, it is possible to hold the grip board horizontally and prevent the grip board from sagging without providing engagement holes at both ends in the width direction of the opening 120 of the case 150 and without increasing the number of parts. Moreover, the stopper 140 and the case 150 are in contact with each other, so that the drooping due to the weight of the grip board is further effectively prevented.

Japanese Patent Laid-Open No. 10-44870 JP 2000-289529 A

  In the technique described in Patent Document 2, when the groove 130 of the second engagement portion 110 and the upper edge portion 170 of the case 150 that forms a part of the opening 120 are engaged or removed. In addition, it is necessary to elastically deform the case 150 in order to widen the opening 120. Therefore, a synthetic resin molded body having a relatively high elasticity is used for the case 150. However, the case 150 of the tonneau cover device is assumed to have a large load resistance that can withstand a situation where a hand or one knee is attached from above, and is generally made of a metal such as aluminum. Therefore, there is a problem that the case cannot be easily elastically deformed.

  In addition, when the tonneau cover device is switched from use to non-use, in addition to the normal operation of releasing the engagement between the locking device on the rear side of the cargo compartment of the vehicle and the locking device 160, the locking device 160 In order to securely engage the groove 130 of the second engagement portion 110 and the upper edge portion 170 of the case 150, the user holds the wound grip board and moves it up and down to widen the opening 120 and further back. The operation to push in is required, which is bothersome.

  The present invention has been made in view of the above problems, and when not in use, the holding board can be easily held horizontally without requiring any special additional parts, additional steps, or special operations as compared with the conventional case. An object of the present invention is to provide a tonneau cover device that can be used.

  The tonneau cover device of the present invention has a tonneau cover sheet that shields a cargo compartment of a vehicle, a rear end of the tonneau cover sheet, and a winding shaft that winds up the tonneau cover sheet, and a winding shaft that is built in, and the tonneau cover sheet enters and leaves A case in which an opening is formed, a gripping board coupled to the tip of the tonneau cover sheet, a locking hook provided at both ends in the width direction of the gripping board and capable of locking with a locking device provided in the vehicle, It is equipped with.

  Moreover, the case has an edge part which forms the edge extended in the longitudinal direction of an opening part, and extends in the drawer | drawing-out direction of a tonneau cover sheet | seat. Furthermore, the latching hook is provided with a clamping portion for clamping and holding the end portion.

  According to the present invention, it is possible to hold the grip board horizontally without adding any special parts or processing steps and without performing any special operation.

  The tonneau cover device 10 is provided with a tonneau cover sheet 40 that covers the luggage compartment, and a case 50 in which a rear end of the tonneau cover sheet 40 is fixed and a winding shaft 70 that winds the tonneau cover sheet 40 is incorporated. . The case 50 is provided with a slit-shaped opening 60 through which the tonneau cover sheet 40 enters and exits the case 50. At the front end of the tonneau cover sheet 40, the grip board 20 provided with the locking hooks 30 having the locking portions 31 and the sandwiching portions 36 at both ends in the width direction is coupled.

  The tonneau cover device 10 is provided at a rear portion of a rear seat of an automobile (not shown). The user grasps the grip board 20 of the tonneau cover device 10 and pulls out the tonneau cover sheet 40 wound and accommodated in the case 50 in the rear direction of the automobile against the urging force of the winding shaft 70. And the extended state of the tonneau cover sheet 40 is maintained by locking the locking portions 31 of the locking hooks 30 to locking devices (not shown) provided on both side surfaces of the rear side of the cargo compartment of the automobile. By maintaining the extended state of the tonneau cover sheet 40, the luggage compartment can be shielded so that the luggage placed in the luggage compartment cannot be seen from outside the vehicle.

  The case 50 is further provided with screw grooves 80 for fixing holders (not shown) attached to both ends of the case 50. In addition, the case 50 is assumed to have a large load resistance that can withstand a situation in which the occupant has a hand or one knee from above, and a metal such as aluminum has a length approximately equal to the interior width of the automobile. By extruding so as to have a cylindrical shape and fitting a holder (not shown) made of a thermoplastic resin such as TPO (olefin-based thermoplastic elastomer) or various rubbers to both ends of the cylindrical extruded product. It is formed.

  A winding shaft 70 to which the rear end of the tonneau cover sheet 40 is fixed is built in the case 50, and both ends of the winding shaft 70 are pivotally supported by holders (not shown) attached to both ends of the case 50. Yes. The winding shaft 70 has a winding mechanism (not shown) that is biased in the direction of winding the tonneau cover sheet 40. A recess having a size substantially the same as that of the holder is provided in the automobile interior, and the tonneau cover device 10 is installed in the luggage compartment by fitting the holder into the recess, so that the tonneau cover device 10 is detachable from the recess. It has become.

  The tonneau cover sheet 40 is made of a flexible and light-shielding material such as vinyl chloride leather.

  The grip board 20 is provided at the tip of the tonneau cover sheet 40, has a shape along the shape of the back door, and is formed of a member having a certain degree of rigidity, for example, a hard resin. The grip board 20 not only facilitates the pulling out of the tonneau cover sheet 40 but also allows the non-rectangular luggage compartment rear portion to be covered along the shape of the back door as described above.

  As shown in FIG. 3A, the cross-sectional shape of the case 50 has a substantially rectangular shape having an upper part 53, a lower part 55, a front side part 56, and a rear side part 54 when viewed from the side of the vehicle. In order from the upper part 53, the front side part 56, the lower part 55, and the rear side part 54 are connected. An upper end portion 51 is provided at an end portion of the upper portion 53 on the rear side portion 54 side, and a lower end portion 52 is provided at an end portion of the rear side portion 54 on the upper portion 53 side.

  In addition, a slit-like opening 60 larger than the width of the tonneau cover sheet 40 is formed along the longitudinal direction of the case 50 at the upper end 51 and the lower end 52. That is, the upper end 51 and the lower end 52 form an edge extending in the longitudinal direction of the opening 60. Therefore, for example, when the rear side portion 54, the upper portion 53, the front side portion 56, and the lower portion 55 are connected and the rear side portion 54 and the lower portion 55 are not connected, the upper end portion 51 is an end of the rear side portion 54 on the lower 55 side. The lower end portion 52 is formed at the end of the lower portion 55 on the rear side portion 54 side. That is, the upper end portion means an end portion that forms the upper edge of the opening portion 60, and the lower end portion means an end portion that forms the lower edge of the opening portion 60.

  In the present embodiment, the upper end portion 51 is configured as a horizontal end portion (horizontal end portion) that extends in the direction in which the tonneau cover sheet 40 is pulled out (rear of the vehicle). However, when the relationship between the upper end portion 51 and the lower end portion 52 is opposite to that described above, that is, the lower end portion 52 may be configured as a horizontal end portion that extends in the direction in which the tonneau cover sheet 40 is pulled out. Both 51 and the lower end 52 may be configured as a horizontal end extending in the drawing direction. In the present invention, at least one of the upper end portion 51 and the lower end portion 52 is an essential constituent element that is a horizontal end portion extending in the direction in which the tonneau cover sheet 40 is pulled out.

  As shown in FIG. 3B, the locking hook 30 has a substantially U-shaped cross section having an upper piece 32, a lower piece 33, and a front piece 35 when viewed from the side of the vehicle. The front piece 35 and the lower piece 33 are connected in order from the upper piece 32. An insertion portion 37 is formed by the upper piece 32, the lower piece 33, and the front piece 35 of the locking hook 30, and the holding board 20 is sandwiched and fixed by the insertion portion 37. The locking hooks 30 are attached and fixed to both ends of the holding board 20 in the width direction by screws or the like.

  Furthermore, the hook 30 in this embodiment is connected to the rear surface of the upper surface 32a of the upper piece 32, and is formed with a pinching portion 36 that extends to the front side of the vehicle. Between the pinching portion 36 and the upper surface 32a. It is comprised so that it may have the clearance gap 38 which faced the vehicle front. A contact portion between the sandwiching portion 36 and the upper piece 32 is a fulcrum portion 39. The sandwiching portion 36, the upper piece 32, and the fulcrum portion 39 constitute a sandwiching portion 80 that sandwiches the upper end portion 51.

  The sandwiching portion 36 is a convex holding portion 30b that protrudes downward in the front, a surface facing the upper piece 32, and a guide portion 36a that extends upward from the holding portion 30b toward the front end. Have. Although not shown, the surface of the sandwiching portion 36 having the guide portion 36a is recessed at the position of the holding portion 30b, but may be flat.

  In addition, this clamping part 80 should just clamp one of the horizontal edge parts among the upper end part 51 and the lower end part 52 which form the opening part 60 of case 50. FIG. Therefore, the sandwiching portion 36 may be configured to extend from the lower surface 33 a of the lower piece 33 of the locking hook 30.

  Thereby, in the state in which the tonneau cover sheet 40 is wound and stored, the upper end portion 51 of the case 50 is held by the holding portion 80 in the gap 38 of the locking hook 30 and the holding board 20 can be held horizontally (see FIG. 2). In addition, a protruding portion 34 that protrudes forward is formed at the upper end of the front piece 35, and the upper end portion 51 of the case 50 is supported to hang down the rear side of the holding board 20 when the weight of the holding board 20 is heavy. Can be prevented. Further, the projecting portion 34 also constitutes a part of the sandwiching portion 80.

  Further, in order to maintain the stretched state in which the tonneau cover sheet 40 is pulled out from the case 50, a locking portion 31 that can be locked to a locking device provided at the rear of the cargo compartment of the automobile is integrally formed on the locking hook 30. (See FIG. 1). The locking hook 30 is preferably made of a material having excellent strength characteristics, wear resistance, and fatigue resistance, such as POM (polyacetal), PP (polypropylene), and PBT (polybutylene terephthalate).

  Here, the operation of the upper end portion 51 and the clamping portion 80 of the case 50 will be described with reference to FIG. FIG. 4 is a schematic diagram for explaining the operation of the upper end portion 51 and the sandwiching portion 80.

  From the extended state of the tonneau cover sheet 40 in which the locking device (not shown) provided on both side surfaces of the cargo compartment and the locking portion 31 of the locking hook 30 are locked, the locking device and the locking hook 30 are engaged. When the stop is released, the tonneau cover sheet 40 is automatically wound in the winding direction (front of the vehicle) by the urging force of the winding shaft 70. Then, the vehicle rear end of the upper end 51 that is the horizontal end is in contact with the end of the sandwiching portion 36. Note that the position of the sandwiching portion 36 at this time is a position indicated by a broken line in FIG. Here, since the pinching portion 36 is formed with a guide portion 36 a having a shape in which the front end of the vehicle extends obliquely upward, the pinching portion 36 is directed downward with respect to the upper end portion 51 by the weight of the grip board 20. Even in the case of displacement, the upper end 51 can be reliably guided toward the gap 38. In addition, a guide portion 36a such as a guide rail may be provided on the side of the luggage compartment to determine the track of the locking hook 30.

  From the state where the vehicle rear end of the upper end 51 of the case 50 and the front end of the pinching portion 36 of the locking hook 30 are in contact with each other, the biasing force F by the take-up shaft 70 is further applied, so that the upper end 51 is separated from the gap 38. As a result, a force that penetrates is generated, and the sandwiching portion 36 is elastically deformed in the direction of widening the gap 38 by the “lever principle” using the fulcrum portion 39 as a fulcrum. Then, the upper end 51 enters the gap 38 and stops against the inner surface of the sandwiching portion 36. At this time, the convex holding portion 30b connected to the guide portion 36a and projecting downward is brought into contact with the upper surface of the upper portion 53, and the upper surface 32a of the locking hook 30 is brought into contact with the lower surface of the upper portion 53. The upper end 51 is held in the holding portion 80 by the elastic force of the holding portion 36.

  In the present embodiment, the holding portion 36b of the sandwiching portion 36 is provided only at one place, but a plurality of holding portions 36b may be provided to form a wavy shape. In this case, the holding portion 36b and the upper surface of the upper portion 53 Therefore, the holding board 20 can be held horizontally more stably. Further, the lower side of the upper end portion 51 is configured to be a thick portion, and the upper surface 32 a of the upper piece 32 of the locking hook 30 corresponding to the position of the upper end portion 51 in a state where the upper end portion 51 is held by the holding portion 80. By forming the concave portion, the upper end portion 51 and the concave portion of the locking hook 30 are fitted, and the holding board 20 can be more stably held horizontally.

  As described above, in the present invention, unlike the above-described prior art, the structure that elastically deforms the hook portion instead of the case, the load resistance required for the tonneau cover device is sacrificed. The holding board can be held horizontally. Since the direction of the urging force for winding the tonneau cover sheet by the winding shaft, the direction in which the upper end portion (horizontal end portion) of the case extends, and the direction of the gap 38 are substantially the same when viewed in the vehicle longitudinal direction, The upper end portion of the case is automatically held by the holding portion 80 of the locking hook using the urging force for winding the tonneau cover sheet. Therefore, it is possible to easily hold the holding board horizontally without requiring any special additional parts, additional processes, or special operations.

  Further, since the upper end portion 51 of the case 50 can be clamped by the clamping portion 80, the locking hook 30 and the rear side portion 54 of the case 50 are not in contact, that is, even when the locking hook 30 is hung from the case 50. The grip board 20 can be held horizontally. Accordingly, the case 50 without the rear side portion 54 of the case 50 is also possible, and the cross-sectional area of the case 50 that is heavy and expensive among the components of the tonneau cover device 10 can be greatly reduced, and the weight can be reduced. This is advantageous in terms of cost. Furthermore, since the upper end portion 51 of the case 50 can be clamped by the clamping unit 80, even if vibration occurs during traveling of the vehicle, the locking hook 30 and the case 50 are not shaken by this vibration. Will not collide with each other. As a result, it is possible to prevent abnormal noise from the tonneau cover device 10 when the vehicle is traveling.

  Next, another embodiment of the case 50 and the locking hook 30 will be described with reference to FIG.

  As shown in FIG. 5A, the upper piece 32 of the locking hook 30 and the sandwiching portion 36 may be connected via a spring member 90 such as a coil spring or a leaf spring. The spring member 90 may be formed integrally with the sandwiching portion 36, formed integrally with the upper piece 32, or formed separately from the sandwiching portion 36 and the upper piece 32. Thereby, since the spring member 90 becomes the fulcrum part 39, the force which clamps the upper end part 51 of the clamping part 80 can be adjusted easily, and horizontal holding | maintenance is performed corresponding to the holding board 20 of various weight. Can do.

  As shown in FIG. 5B, a recess 91 is provided in a portion of the upper piece 53 of the case 50 where the holding portion 36 b of the locking hook 30 abuts in a state where the upper end portion 51 is held by the holding portion 80. Also good. Thereby, the holding | maintenance part 36b and the hollow 91 fit, and the horizontal holding | maintenance of the holding board 20 can be performed more stably.

  As shown in FIG. 5C, since the upper end portion 51 of the case 50 can be held by the holding portion 80, the case 50 can be formed only by the upper portion 53 and the front side portion 56. Thereby, the cross-sectional area of the case 50 which is heavy and expensive among the components of the tonneau cover device 10 can be greatly reduced, which is advantageous in terms of weight reduction and cost. Note that the case 50 may be formed by only the lower portion 55 and the front side portion 56, and an end portion serving as a horizontal end portion may be formed in the lower portion 55.

  As shown in FIG. 5 (d), the protruding portion 34 of the locking hook 30 is extended to the front of the vehicle, and the pinching portion 36 is also correspondingly extended. The upper end portion of the case 50 is thereby extended by the protruding portion 34 and the pinching portion 36. 51 may be clamped. Further, in accordance with this, an upward thick portion 92 may be formed on the upper end portion 51, and the upper end portion 51 may be caught by the holding portion 36b in a state where the upper end portion 51 is sandwiched by the sandwiching portion 80. As a result, the upper end portion 51 can be moved forward of the vehicle by an amount corresponding to the extension of the protruding portion 34, so that the upper portion 53 of the case 50 can be shortened in the front direction of the vehicle, and the cross-sectional area of the case 50 is reduced. A stable holding of the grip board 50 can be performed.

  It should be noted that a plurality of embodiments of the case 50 and the locking hook 30 described above may be combined.

  In the above-described embodiment, the locking hook 30 has the front piece 35 and the lower piece 33 connected in order from the upper piece 32. However, as shown in FIG. 1, the locking hook 30 is formed so that the upper piece 32 and the lower piece 33 are connected to each other at a surface that does not face the opening 60 (a surface that faces the vehicle side portion). For this reason, the front piece 32 and the lower piece 33 or the upper piece 32 and the front piece 35 may not be connected. It is also possible to have a configuration in which only a part is connected.

  In the above description of the embodiment, the tonneau cover device has been described as applied to an automobile. However, any type of vehicle may be used, and further, as long as the present invention can be applied. I do not care.
