Description

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

  In hatchback type automobiles, etc., where the luggage compartment is not separated from the passenger compartment and the cargo compartment is provided at the rear of the rear seat, the luggage compartment is not visible from the outside. A tonneau cover device is provided near the rear portion of the rear seat.

  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.

  Therefore, Patent Document 1 discloses a configuration of an example of a tonneau cover device of related technology that solves this problem. 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 tonneau cover apparatus according to the related art that can solve the problem occurring in the tonneau cover apparatus of Patent Document 1 is disclosed in Patent Document 2. In FIG. 1, the schematic of the cross section of another example of the tonneau cover apparatus of related technology 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 (width in the vertical direction) of the opening 120 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

  However, in the technique described in Patent Document 2, 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 disengaged. When doing so, it is necessary to elastically deform the case 150 in order to widen the opening 120. Therefore, due to repeated use, the groove 130 of the second engagement portion 110 and a part of the opening 120 of the case 150 are formed due to wear and breakage of the second engagement portion 110 and a decrease in the elastic force of the case 150. There is a possibility that the engagement with the upper edge portion 170 to be loosened becomes impossible to fix, and an abnormal noise may be generated by vibration.

  Further, the tonneau cover device is usually disposed below as viewed from the user. Therefore, when the tonneau cover sheet 100 is pulled out from the case 150, the tonneau cover sheet 100 tends to be drawn obliquely upward with respect to the substantially horizontal original pulling direction, and the tonneau cover sheet 100 and the upper edge 170 of the case 150 May cause a rubbing sound due to interference.

  The present invention has been made in view of the above problems, and can easily hold the grip board horizontally without requiring any special additional parts or additional steps when not in use, compared to the tonneau cover device of the related art. It is an object of the present invention to provide a tonneau cover device capable of performing the above.

  A tonneau cover device according to 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 the tonneau cover sheet, and a cylindrical shape. A built-in case in which an opening for entering and exiting the tonneau cover sheet is formed in a corner formed on the upper part and a side part adjacent to the upper part in the pulling out direction of the tonneau cover sheet, and a grip board coupled to the tip of the tonneau cover sheet A hook provided on both ends of the holding board in the width direction and having convex portions protruding from the surface; an end on the opening side of the upper part of the case; and a side part adjacent to the upper part of the case in the direction of pulling out the tonneau cover sheet And a support portion that supports the locking hook in a state where the tonneau cover sheet is wound around the winding shaft.

  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, a grip board 20 provided with a locking hook 30 having locking portions 31 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. And the tonneau cover sheet | seat 40 is maintained by the latching hook 30 being latched by the latching device not shown provided in the both sides | surfaces of the back of the loading compartment of a motor vehicle. 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.

  As shown in FIG. 4A, the cross-sectional shape of the case 50 has a substantially rectangular shape having an upper portion 53, a lower portion 55, a front side portion 56, and a rear side portion 54 as seen from the vertical direction and the front and rear direction 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 edge portion 51 is provided at an edge portion of the upper portion 53 on the rear side portion 54 side, and a lower edge portion 52 is provided at an edge portion of the rear side portion 54 on the upper portion 53 side. In addition, it is preferable that the upper edge part 51 and the lower edge part 52 have a curvature and are thick.

  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 edge 51 and the lower edge 52. In other words, in the present invention, the slit-shaped opening 60 constituted by the upper edge portion 51 and the lower edge portion 52 is not formed only by the rear side portion 54 of the case 50. In the present embodiment, the upper portion 53 of the case 50 and the side portion adjacent to the upper portion 53 of the case 50 in the drawing direction of the tonneau cover sheet 40 and located in the same direction as the drawing direction of the tonneau cover sheet 40, that is, the present embodiment. In the form, it is an indispensable constituent element that the opening 60 is formed so as to cut out the corner at the position of the corner formed by the rear side portion 54.

  The opening 60 will be described in more detail with reference to FIG. 4A. In the related art, the opening is formed only on the side of the case. As shown by an imaginary line (two-dot chain line) in FIG. Corners X are formed. In the present invention, the opening 60 is formed by cutting out the corner portion X formed by virtually extending the upper portion 53 of the case 50 and the side portion adjacent to the upper portion 53 of the case 50 in the pulling-out direction of the tonneau cover sheet 40. Is formed. Since it is important for the case 50 of the present invention to have one such corner, the case 50 may have a cross section having a single corner or a polygon. It does not matter.

  The case 50 is further provided with screw grooves 80 for fixing holders (not shown) attached to both ends of the case 50.

  The case 50 is formed by extruding a metal such as aluminum so as to have a cylindrical shape having a length substantially equal to the interior width of the automobile, and TPO (olefin-based thermoplastic elastomer) is formed at both ends of the cylindrical extruded product. It is formed by fitting a holder (not shown) made of a thermoplastic resin such as various rubbers or the like. 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 that follows the shape of the back door, and is formed of 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.

  The locking hook 30 has a substantially U-shaped cross section having a sandwiching upper piece 32, a sandwiching lower piece 33, and a sandwiching piece 35 as viewed from the vertical direction and the front-rear direction of the vehicle. The pre-clamping piece 35 and the clamping lower piece 33 are connected in order from 32. An insertion portion 37 is formed by the upper clamping piece 32, the lower clamping piece 33, and the pre-clamping piece 35 of the locking hook 30, and the holding board 20 is clamped 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.

  As shown in FIG. 4B, the hook lower surface 30a, which is the lower surface of the holding lower piece 33, is formed substantially parallel to the insertion direction of the holding board 20 into the insertion portion 37, and is the front surface of the hook that is the front surface of the pre-holding piece 35. 30 b is formed substantially perpendicular to the insertion direction of the holding board 20 into the insertion portion 37. Further, the locking hook 30 is provided with a convex portion 34 formed so as to protrude from the hook front surface 30b, and the hook front surface 30b and the convex upper surface 34a of the convex portion 34 are configured to be substantially perpendicular. However, the grip board 20 may jump up due to vibrations or the like while the vehicle is running. In the case of the configuration of the hook front surface 30b and the convex upper surface 34a, as shown in FIG. 5, the grip board 20 rides on the upper portion 53 of the case 50 together with the locking hook 30, that is, the upper portion 53 of the case 50. The grip board 20 may be stabilized in a state where the grip board 20 is vertical. In this case, the driver's field of view is narrowed by the gripping board 20 which is stable in the vertical state, and there is a danger. Therefore, as shown in FIG. 6, the hook front surface 30 b is tilted in the direction opposite to the protruding direction of the convex portion 34 (the drawing direction of the tonneau cover sheet 40) so that the hook front surface 30 b and the convex portion upper surface 34 a form an obtuse angle. May be. With this configuration, even if the gripping board 20 jumps up, as shown in FIG. 7, the locking hook 30 does not stabilize on the upper part 53 of the case 50 and rotates in the direction of the arrow A to grip it. The board 20 returns to the state before jumping up. Therefore, safety during vehicle travel can be maintained.

  As shown in FIG. 4B, it is preferable that a slope portion 36 is formed on the surface of the connection portion between the pre-clamping piece 35 and the clamping lower piece 33. Further, as shown in FIG. 6, it is more preferable that the convex portion lower surface 34 b of the convex portion 34 is smoothly connected to the hook lower surface 30 a via the slope portion 36. When the tonneau cover sheet 40 is wound by the weight of the grip board 20, the hook front surface 30b and the lower edge portion 52 of the case 50 may come into contact with each other (see FIG. 8A). Since the locking hook 30 of the present invention is provided with the slope portion 36, the locking hook 30 is pulled up along the slope portion 36 (see FIG. 8B). Then, as shown in FIG. 3, the lower surface 30 a of the locking hook 30 and the lower edge portion 52 of the case 50 can come into contact with each other. Therefore, the hook 30 is prevented from being caught by the lower edge portion 52 of the case 50 when the tonneau cover sheet 40 is wound up.

  Further, since the convex portion lower surface 34b of the convex portion 34 is smoothly connected to the hook lower surface 30a via the slope portion 36, the slope portion 36 can serve as a rib that reinforces the convex portion 34. It is possible to prevent the protrusion 34 from being bent or deformed.

  Although various embodiments of the locking hook 30 will be described later, the shapes of the hook front surface 30b and the slope portion 36 described above can also be suitably used for the locking hook 30 in this case.

  The dimension of the locking hook 30 is set so that the height is higher than the height of the opening 60, and the locking hook 30 is configured to prevent the locking hook 30 from entering the inside of the case 50.

  In order to maintain the extended state in which the tonneau cover sheet 40 is pulled out from the case 50, the locking hook 30 is integrally formed with a locking portion 31 that can be locked to a locking device provided at the rear of the cargo compartment of the automobile. (See FIG. 2). 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).

  With the above configuration, when the tonneau cover sheet 40 is housed in the case 50, the lower edge portion 52 of the case 50 is locked substantially perpendicularly to the hook lower surface 30a of the locking hook 30, as shown in FIG. The hook 30 is supported, and the upper edge portion 51 of the case 50 supports the locking hook 30 substantially perpendicular to the hook front surface 30 b of the locking hook 30. That is, the lower edge portion 52 and the upper edge portion 51 constitute a support portion for the locking hook 30. As a result, the downward hanging of the vehicle due to the weight of the grip board 20 to which the locking hook 30 is attached is supported by the lower edge portion 52 as a fulcrum, and the case 50 is biased by the winding shaft 70. The winding force to the inside holds the holding board 20 in a horizontal state by the upper edge portion 51 being laterally supported. Further, the locking hook 30 is provided with a convex portion 34 protruding from the hook front surface 30 b of the locking hook 30. Therefore, even if the weight of the gripping board 20 is large, or when a force that rotates the gripping board 20 in the direction in which the gripping board 20 hangs down due to vibration during traveling of the vehicle, the upper edge portion 51 of the case 50 is used. And the hook protrusion upper surface 34a come into contact with each other to prevent the grip board 20 from rotating, so that the grip board 20 can be kept in a horizontal state.

  In the tonneau cover device of the related art, when the tonneau cover sheet is pulled out from the case, the tonneau cover sheet may be pulled obliquely upward with respect to the substantially horizontal original pulling direction. Interference could occur. However, in the tonneau cover device 10 of the present invention, the opening 60 is provided at the corner of the case 50. Therefore, even when the tonneau cover sheet 40 is pulled obliquely upward from the substantially horizontal pulling direction, the tonneau cover sheet 40 and the upper edge portion are provided. No interference with 51 occurs. Therefore, the generation of rubbing noise can be prevented.

  FIG. 9A is a schematic view of the state in which the winding direction of the tonneau cover sheet 40 is changed in the cross-sectional view of FIG. 3, and shows the state in which the tonneau cover sheet 40 is wound from below the winding shaft 70. FIG. 9B is a schematic view of the state in which the winding direction of the tonneau cover sheet 40 is changed in the cross-sectional view of FIG. 3, and shows a state in which the tonneau cover sheet 40 is wound from above the winding shaft 70.

  As shown in FIG. 9A, when the tonneau cover sheet 40 is wound around the take-up shaft 70 from below the take-up shaft 70, when the tonneau cover sheet 40 is extended, when the tonneau cover sheet 40 is pulled out in the horizontal direction, Since the lower edge portion 52 of the case 50 and the tonneau cover sheet 40 may interfere with each other, in this case, the tonneau cover sheet 40 is preferably pulled out obliquely upward with respect to the horizontal direction.

  As shown in FIG. 9B, when the tonneau cover sheet 40 is wound around the winding shaft 70 from above the winding shaft 70, the tonneau cover sheet 40 is wound around the winding shaft 70 and stored in the case 50. Then, the tonneau cover sheet 40 and the grip board 20 are connected in a substantially straight line. Therefore, when the tonneau cover sheet 40 is pulled out and expanded in the horizontal direction, the tonneau cover sheet 40 passes smoothly through the opening 60 without interfering with the lower edge portion 52. Even when the tonneau cover sheet 40 is pulled obliquely upward with respect to the horizontal direction, the tonneau cover sheet 40 passes through the opening 60 smoothly without interfering with the upper edge 51 and the lower edge 52.

  As described above, the tonneau cover device 10 according to the present invention can reliably hold the grip board 20 horizontally. Therefore, it is not necessary to elastically deform the case 150 in order to enlarge the opening 120 as in the above-mentioned related art tonneau cover device (see, for example, FIG. 1), and the locking tool 160 is damaged or worn due to repeated use. Various problems such as generation of abnormal noise due to insufficient fixation of the locking device 160 due to a decrease in the elastic force of the case 150 can be prevented. Moreover, since it is a simple structure which does not require special additional parts and an additional process, and furthermore, since the slit-shaped opening 60 is located at a position where the corner of the case 50 is cut away, it is generally included in the tonneau cover device. However, the cross-sectional area of the case 50, which is often made of expensive materials, can be reduced, and the material cost can be reduced. For this reason, the cost is extremely superior to the tonneau cover device of the related art.

  Next, another embodiment of the locking hook 30 will be described with reference to FIGS. 10A to 10E.

  As shown in FIG. 10A, a buffer layer 90 may be provided on at least one of the locking hook 30 and the case 50 at a portion where the locking hook 30 and the case 50 abut. Thereby, generation | occurrence | production of the sound at the time of the latching hook 30 and case 50 contact | abutting and generation | occurrence | production of the noise by vibration can be suppressed effectively. The buffer layer 90 may be formed, for example, by attaching a flexible skin material such as a non-woven fabric, or by molding a part of the contact portion between the locking hook 30 and the case 50 with a soft resin. it can.

  As shown in FIG. 10B, a concave groove 91 into which the lower edge portion 52 of the case 50 is fitted may be provided on the hook lower surface 30 a of the locking hook 30. Thereby, in the state which hold | maintained the holding board 20 horizontally, the position shift of the holding board 20 resulting from running vibration etc. can be suppressed effectively.

  As shown in FIG. 10C, an engaging portion (protruding portion) formed in a claw shape that protrudes upward from the upper surface portion 51 a of the protruding portion 34 of the protruding portion 34 of the locking hook 30, that is, upward. 93 may be provided. Thereby, even when the own weight of the holding board 20 is large, the hooking of the engaging board 93 and the upper edge part 51 and the increase in friction can suppress the rotation of the holding board 20 in the drooping direction more effectively. In addition, since the engaging portion 93 is caught by the upper edge portion 51 when the grip board 20 jumps up and returns during traveling of the vehicle, it is possible to prevent the engaging hook 30 from jumping out from the case 50.

  As shown in FIG. 10D, the locking hook 30 is configured with a portion where the convex portion 34 extends forward and a portion which protrudes and extends upward from the portion where the convex portion 34 is extended and formed. An extended portion (projecting portion) 94 may be provided. As a result, the upper edge portion 51 can be moved forward of the vehicle by the amount of the extension portion 94, so that the cross-sectional area of the case 50, which is an expensive member in the tonneau cover device, can be reduced. Is advantageous.

  As shown in FIG. 10E, a magnetic body 95 may be provided on both sides of the locking hook 30 and the case 50 at a portion where the locking hook 30 and the case 50 abut. As a result, the locking hook 30 and the case 50 are attracted and in close contact with each other, so that rattling due to vibration can be prevented and the holding board 20 can be held horizontally more stably. Further, the pull-out resistance due to the magnetism of the magnetic body 95 generated when the tonneau cover sheet 40 is pulled out by pulling the grip board 20 from the winding state in which the tonneau cover sheet 40 is wound around the winding shaft 70 and stored in the case 50. However, the user is given a so-called “click feeling” when the tonneau cover sheet 40 is first pulled out, and the operability is improved. The magnetic body 95 may be affixed to a portion where the locking hook 30 and the case 50 are in contact with each other. In the case of the case 50 made of aluminum, if the case 50 is made magnetic by using an alumite process that is usually performed for the purpose of scratch resistance, it is advantageous in terms of cost and appearance by reducing the number of parts.

  The locking hook 30 can be configured by combining a plurality of the above-described embodiments.

  Further, as shown in FIG. 11, the lower edge portion 52 of the case 50 may be extended in the vehicle front-rear direction to form a support portion 92. Thereby, the contact area of the lower edge part 52 and the lower surface 30a of the latching hook 30 increases, and the holding board 20 can be held horizontally more stably.

  In the present invention, the protrusion 34 protruding from the hook front surface 30 b of the locking hook 30 is provided, but it may be protruded upward from the hook upper piece 32.
