Description

  The present invention relates to a tonneau cover device that opens and closes an upper surface of a luggage room of a vehicle.

  The tonneau cover device is a device for covering the upper surface of the luggage room of the vehicle with a sheet-like tonneau cover body so that the luggage accommodated in the luggage room is not visually recognized from outside the vehicle room.

  One end of the tonneau cover body is generally held by winding means disposed on the back surface of the back sheet. A general tonneau cover device is constituted by the winding means and the tonneau cover body. The winding means is biased in the direction of winding the tonneau cover body. Therefore, the tonneau cover body can be pulled out in the direction of the luggage room and is automatically wound by the winding means.

  When opening and closing the upper surface of the luggage room with such a tonneau cover device, the opening and closing operation is performed manually. That is, when covering the luggage room with the tonneau cover body, the tonneau cover body is pulled out from the winding means in the direction of the luggage room, and the drawer end of the tonneau cover body is fixed at a position near the back door of the luggage room. When opening the luggage room, remove the end of the drawer and gently release your hand so that the tonneau cover body is wound up by the winding means.

  Here, in the tonneau cover device that manually opens and closes the luggage room, the passenger is forced to perform complicated operations when opening and closing the luggage room, and there is a problem in that it is difficult to use. Furthermore, the operation of pulling out the tonneau cover body after putting the luggage into the luggage room is easily forgotten, and there is a problem that the luggage room is easily left open.

  For this reason, in recent years, a tonneau cover device has been developed in which the tonneau cover body is wound around the winding means in conjunction with the opening operation of the back door and pulled out in conjunction with the closing operation of the back door (for example, Patent Document 1). .

  The tonneau cover device disclosed in Patent Literature 1 includes a tonneau cover main body, a winding means, a back door side wire, a tonneau cover side wire, and a winder. The back door side wire has one end held by the back door and the other end held by the winder. The winder is biased in the direction of winding the back door side wire. Further, one end of the tonneau cover side wire is held by the drawer end of the tonneau cover, and the other end is connected to the back door side wire.

  When the back door is opened, the back door side wire is pulled by the back door, and the back door side wire held by the winder is pulled out, so that the tension of the tonneau cover side wire connected to the back door side wire is increased. Loosen. When the tension of the tonneau cover side wire is loosened, the tonneau cover body is wound around the winding device for the tonneau cover body and the luggage room is opened.

  When the back door is closed, pulling of the back door side wire by the back door is released, and the back door side wire is wound around the winder. At this time, since the tonneau cover side wire connected to the back door side wire is pulled, the tonneau cover body is pulled out and the luggage room is closed.

  According to the tonneau cover device disclosed in Patent Document 1, since the opening and closing of the tonneau cover body is interlocked with the opening and closing of the back door, the above-described complicated operation is not required for opening and closing the tonneau cover body. Since the tonneau cover body covers the upper surface of the luggage room as the back door is closed, the luggage room is securely closed when the back door is closed.

However, since the tonneau cover device disclosed in Patent Document 1 opens and closes the tonneau cover body with complicatedly wired wires, the tonneau cover body can be opened and closed satisfactorily depending on the usage state. It may disappear. Furthermore, when the back door is closed, the wire may be pinched by the back door depending on the use state. For these reasons, there is a problem that the tonneau cover device is likely to break down.
JP 2001-63468 A

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a tonneau cover device that opens and closes in conjunction with opening and closing of a back door and is less likely to fail.

The tonneau cover device of the present invention that solves the above-mentioned problem is that the one end of the sheet-like tonneau cover body is held by the winding means that is urged in the winding direction, and the tonneau cover body winds in conjunction with the opening operation of the back door. A tonneau cover device that is wound around the means and pulled out in conjunction with the closing operation of the back door,
A first slide rail provided in a passenger compartment and extending in a pulling direction of the tonneau cover main body, a first slider for holding a pulling end portion of the tonneau cover main body and slidably held on the first slide rail, and provided on the vehicle body A second slide rail extending from the vicinity of the extended end of the first slide rail in a direction intersecting the first slide rail, a second slider slidably held on the second slide rail, the first slider, and the second slider And a connecting means for connecting the second slider and the back door.

  Preferably, the connecting means includes a substantially cylindrical first rod and a substantially rod-shaped second rod, and the second rod is retractable by entering and exiting the cylinder of the first rod.

  The connecting means is preferably held so as to be swingable with respect to at least one of the back door and the second slider.

  It is preferable that the drawer end portion is detachably held on the first slider. In this case, it is desirable that the connector is made of a resin plate and presses the first slider in the direction of the take-up means as the second slider slides during the back door opening operation.

  The connector includes a first connector having one end fixed to the first slider, a second connector having one end fixed to the second slider, and a cylindrical first winding having different diameters. And the second winding part rotate coaxially and hold the other end of the first connector on the outer peripheral surface of the first winding part and the other end of the second connector on the outer peripheral surface of the second winding part. It is preferable to include a connector winding means for holding the connector.

  1 and 2 are sectional views schematically showing an example of the tonneau cover device of the present invention, and the operation of the tonneau cover device of the present invention will be described below.

  In the tonneau cover device 1 of the present invention, as shown in FIG. 1, the connecting means 3 connected to the back door 2 is moved by the opening operation of the back door 2, and the second slider 5 connected to the connecting means 3 is moved. It slides on the second slide rail 6 in a direction approaching the extension end 8 of the first slide rail 7. By this sliding movement, the connecting tool 11 that connects the second slider 5 and the first slider 10 is loosened, so that the tonneau cover body 12 is wound around the winding means 13 and the drawer end 16 of the tonneau cover body 12 is held. The first slider 10 is slid on the first slide rail 7 in the direction opposite to the pulling direction, and the upper surface of the luggage room 15 is opened.

  Then, as shown in FIG. 2, the connecting means 3 connected to the back door 2 is moved by the closing operation of the back door 2, and the second slider 5 connected to the connecting means 3 is moved onto the second slide rail 6. Is slid in a direction away from the extended end 8 of the first slide rail 7. Then, the connecting tool 11 is pulled by the sliding movement of the second slider 5, and the first slider 10 connected to the connecting tool 11 slides on the first slide rail 7. Since the first slide rail 7 extends in the pulling direction of the tonneau cover body 12, the sliding movement of the first slider 10 causes the pulling end 16 held by the first slider 10 and the first slider 10 to be pulled in the pulling direction. As a result, the tonneau cover body 12 held by the first slider 10 is pulled out. For this reason, the upper surface of the luggage room 15 is covered with the tonneau cover body 12.

  Thus, according to the tonneau cover device of the present invention, since the tonneau cover body opens and closes in conjunction with the opening and closing of the back door, no complicated operation is required to open and close the tonneau cover body. Moreover, in the tonneau cover device of the present invention, wires that are complicatedly wired are not required, so that the wires do not get tangled with each other. Further, the connecting means is moved by the closing operation of the back door, and the movement of the connecting means is directly transmitted to the second slider so that the second slider is forcibly slid. Part of the device is never caught between the back doors. For these reasons, problems such as failure of the tonneau cover device due to opening and closing of the back door are reliably avoided.

  Further, when the connecting means is provided with a substantially cylindrical first rod and a substantially rod-shaped second rod, and the second rod is retractable by moving in and out of the cylinder of the first rod. Because the connecting means expands and contracts, the tonneau cover body can reliably cover the upper surface of the luggage room even when the arrangement length of the second slide rail is shortened or the back door is greatly opened. It is possible to deal with vehicles having various shapes.

  Furthermore, when the connecting means is held so as to be swingable with respect to at least one of the back door and the second slider, the arrangement direction of the second slide rail with respect to the back door can be set in various directions. Can be set.

  When it is assumed that the drawer end is detachably held on the first slider, the drawer end is removed from the first slider so that the upper surface of the luggage room is opened even when the back door is closed. be able to. In this case, even a large luggage can be accommodated in the luggage room without being interfered with the tonneau cover body.

  Further, in this case, the coupling tool can be made of a resin plate, and the first slider can be pressed in the direction of the winding means as the second slider slides during the back door opening operation. In this case, even if the drawer end is removed from the first slider and the urging force of the winding means does not act on the first slider, the first slider and the first slider are coupled to the first slider when the back door is closed. Since the connecting tool moves in the winding direction of the tonneau cover body, problems such as interference of the connecting tool with the opening and closing of the back door and pinching by the back door are avoided.

  The connecting tool includes a first connecting tool having one end fixed to the first slider, a second connecting tool having one end fixed to the second slider, a first winding portion having a cylindrical shape with different diameters, and a second connecting tool. The second winding portion rotates coaxially, and the other end of the first connector is held on the outer peripheral surface of the first winding portion, and the other end of the second connector is held on the outer peripheral surface of the second winding portion. And a connector winding means. In this case, since the winding length and the drawing length of the first connector and the second connector can be appropriately set, the slide movement distance of the first slider and the slide movement distance of the second slider are set to desired lengths. This makes it possible to deal with vehicles having various shapes.

  A tonneau cover device according to the present invention includes a tonneau cover main body, a winding means, a first slide rail, a first slider, a second slide rail, a second slider, a coupling tool, and a coupling means.

  The tonneau cover body has a sheet-like shape and covers the upper surface of the vehicle luggage room when the back door is closed. The tonneau cover body has one end held by the winding means and the other end of the drawer end held by the first slider. Further, the tonneau cover body is made of a soft material that can be taken up by the take-up means and can be pulled out and developed on the upper surface of the luggage room. The drawer end portion of the tonneau cover body preferably has a relatively high rigidity in order to pull out the tonneau cover body uniformly. For example, only the drawer end portion of the tonneau cover body is formed thick or the drawer end portion Only a hard material can be used.

  The winding means is a member that holds one end of the tonneau cover body and is urged in a winding direction that is a direction of winding the tonneau cover body. The urging of the winding means in the winding direction can be performed by a known urging means such as a winding spring. The urging force of the winding means may be such that the tonneau cover body is wound up when the connecting tool is loosened during the opening operation of the back door and the tonneau cover body is pulled out during the closing operation of the back door.

  The first slide rail is a member that is provided in the vehicle compartment and extends in the pulling direction of the tonneau cover body. The first slide rail is disposed in the pulling direction of the tonneau cover body, that is, from the back seat side toward the back door side. The first slide rail may be disposed so as to be exposed in the vehicle interior, or may be disposed so as not to be exposed entirely in the vehicle interior, for example, embedded in a side wall surface of the luggage room. The first slide rail only needs to hold the first slider in a slidable manner. For example, when the first slider is provided with a protrusion or groove, the slide groove or slide protrusion that slide-fits the protrusion or groove is not provided. It is extended in the arrangement direction of the first slide rail.

  The first slider is a member that holds the drawer end portion of the tonneau cover body, is slidably held on the first slide rail, and is connected to the second slider via a connector. The first slider is provided with a groove, a protrusion, or the like for sliding on the first slide rail. Further, the first slider and the drawer end may be fixed to each other, or may be locked to each other so as to be removable.

  The connector is a part that connects the first slider and the second slider, and is a part that slides the first slider with the sliding movement of the second slider when the back door is closed. The coupling tool only needs to be strong enough to slide the first slider by sliding the second slider. For example, a wire or the like can be used.

  Here, as described above, when the drawer end is detachably held by the first slider, when the drawer end is removed from the first slider, the urging force by the winding means is not transmitted to the first slider, The first slider does not slide in the winding direction. On the other hand, since the second slider remains connected to the connecting means, the second slider slides toward the extended end of the first slide rail as the back door opens. For this reason, at the time of the opening operation of the back door, the first slider and the second slider are arranged at positions close to each other, and the connecting tool for connecting the first slider and the second slider is the first slide rail and the second slide rail. May protrude from the gap. In this case, the coupling tool may be deformed or entangled depending on the positions of the first slider, the second slider, and the back door. Further, the coupling tool may interfere with the closing operation of the back door, or the back door may be closed. There is a possibility that the connecting tool may be caught between the vehicle body and the back door during operation.

  Therefore, when the drawer end is detachably held by the first slider, it is preferable to separately provide a slider moving means for sliding the first slider in the winding direction of the tonneau cover body.

  The slider moving means can be used such that the first slider is slid in the winding direction of the tonneau cover body when the back door is opened and does not obstruct the sliding movement of the first slider in the pulling direction when the back door is closed. . For example, the second winding means is provided in the vicinity of the winding means, and one end of the wire is held by the second winding means and the other end of the wire is connected to the first slider. Are preferably used. In such a slider moving means, the first slider can be slid in the winding direction by winding the wire by the urging force of the second winding means.

  Further, for example, the coupling tool may be made of a relatively hard material such as a resin plate, and the first slider may be pressed in the direction of the winding means as the second slider slides during the back door opening operation. it can. In this case, the connecting tool becomes the slider moving means.

  A 2nd slider is a part hold | maintained to the 2nd slide rail so that the edge part by the side which is not connected with the 1st slider among connection tools is connected. Similar to the first slider, the second slider is provided with a groove, a projection, or the like for sliding on the second slide rail.

  The second slide rail is a member that is provided on the vehicle body and extends in the direction intersecting the first slide rail from the vicinity of the extended end of the first slide rail. The second slide rail can be provided inside the vehicle compartment, or can be provided outside the vehicle compartment such as a gap between the outside of the luggage room and the back door of the vehicle body. The second slide rail extends from near the extension end of the first slide rail. For this reason, the length of the connecting tool for connecting the first slider and the second slider is minimal, and for example, the connecting tool is prevented from being entangled even when the connecting tool is constituted by a wire or the like.

  In the tonneau cover device of the present invention, the second slide rail extends in a direction intersecting the first slide rail. Usually, since the tonneau cover main body covers the upper surface of the luggage room over almost the entire length in the depth direction, the first slide rail extends substantially the entire length in the depth direction of the luggage room. Here, the second slide rail extends in a direction intersecting the first slide rail, so that the tonneau cover body covers almost the entire length of the luggage room and secures a wide space in the luggage room that can accommodate luggage. it can.

  The connecting means is a member connected to the second slider and the back door. The connecting means transmits the closing operation of the back door to the second slider, and slides the second slider in a direction away from the extended end of the first slide rail. Then, the opening operation of the back door is transmitted to the second slider, and the second slider is slid in the extension end direction of the first slide rail. Therefore, the connecting means only needs to transmit the opening / closing of the back door to the second slider and slide the second slider, and the shape thereof may be, for example, a rod or the like that is difficult to deform, or may be a wire or the like. It may be easily deformed. Of these, the connecting means which is not easily deformed is particularly preferably used in order to reliably transmit the opening / closing operation of the back door by the second slider.

Hereinafter, the tonneau cover device of the present invention will be described with reference to the drawings.

(Example 1)
The tonneau cover apparatus of the first embodiment is disposed in a vehicle having a relatively shallow luggage room, and has a rod-like connecting means that can be expanded and contracted. FIG. 3 is a perspective view schematically showing the tonneau cover device of the first embodiment, and FIGS. 4 and 5 are sectional views schematically showing the tonneau cover device of the first embodiment.

  In the tonneau cover device 20 of the first embodiment, the winding means 21 is formed in a long and hollow cylindrical shape, and is fixed so as to extend to the left and right of the back surface of the back seat 22 of the vehicle. Biasing means (not shown) composed of winding springs are arranged at both ends in the longitudinal direction in the inside of the cylinder of the winding means 21. Both ends of the rod-shaped shaft portion 23 are held by this urging means. Further, one end of the tonneau cover body 25 is held on the shaft portion 23. Since both ends of the shaft portion 23 are held by the biasing means, the winding means 21 is biased in the winding direction, which is the direction in which the tonneau cover body 25 is wound.

  The tonneau cover main body 25 has a sheet-like shape, and the drawer end 26 which is the end facing away from the end held by the winding means 21 is constituted by a resin columnar body, and the other parts The sheet portion 27 is made of a thin cloth.

  A first slide rail 31 extending in the direction of the back door 30 is embedded in each of the left and right side walls of the luggage room 28 located behind the back seat 22 in the vehicle. The first slide rail 31 has a slide groove 32 extending in the longitudinal direction, and the inside of the slide groove 32 is exposed to the luggage room 28. Inside each slide groove 32, a first slider 33 having a U-shaped cross section is slidably held.

  The first slider 33 is held by the first slide rail 31 in a direction in which the inside of the U-shape is directed into the luggage room 28. A drawer end portion 26 of the tonneau cover body 25 is held inside the U-shape of each first slider 33.

  The second slide rails 35 are disposed one by one at the position of the gap with the back door 30 in the left and right ends of the vehicle body outside the luggage room 28. The second slide rail 35 has a slide groove 36 that opens to the back door 30 side, and extends from a position near the extension end 37 of the first slide rail 31 toward the lower side of the vehicle body.

  A second slider 38 is slidably held in the slide groove 36 of each second slide rail 35. The second slider 38 is slidably fitted into the slide groove 36 of the second slide rail 35 and a part thereof is exposed from the opening of the slide groove 36 to the back door 30 side. A portion of the second slider 38 exposed to the back door 30 is provided with a rod-shaped first pivot shaft portion 40 extending in the left-right direction. One end of a connecting means 41 is swingably held by the first pivot shaft portion 40 of each second slider 38.

  The connecting means 41 has a rod-like shape including a substantially cylindrical first rod 42 and a substantially rod-like second rod 43. The second rod 43 is inserted into the cylinder of the first rod 42, and the connecting means 41 is telescopic as the second rod 43 enters and exits the cylinder of the first rod 42. A hole-shaped first rocking portion 45 is provided at the end of the second rod 43 of the connecting means 41, and the first pivot shaft portion 40 of the second slider 38 is inserted into the first rocking portion 45. Thus, the connecting means 41 swings with respect to the second slider 38. In addition, a hole-like second swinging portion 46 is provided at the end of the first rod 42 in the connecting means 41. The second swinging portions 46 are respectively inserted into second pivotal support shaft portions 47 provided respectively at the left and right end portions of the back door 30 so as to be swingable with respect to the back door 30. .

  The first slider 33 and the second slider 38 are connected by a connecting tool 48 made of a metal wire. A communication hole 50 is provided in the rear portion of the vehicle body to communicate between the outside and the interior of the vehicle. The connector 48 is inserted into the communication hole 50 and disposed outside the vehicle interior with the first slider 33 disposed in the vehicle interior. The second slider 38 is connected.

  The tonneau cover apparatus 20 of the first embodiment operates as follows.

  When the back door 30 is opened, as shown in FIG. 4, the connecting means 41 held by the back door 30 moves upward while extending. The second slider 38 held by the connecting means 41 slides upward on the second slide rail 35 and is disposed near the extension end 37 of the first slide rail 31. By the sliding movement of the second slider 38, the connecting tool 48 that connects the first slider 33 and the second slider 38 is loosened. Here, the drawer end 26 of the tonneau cover body 25 is held by the first slider 33, and the other end of the tonneau cover body 25 is held by the winding means 21. By releasing the pulling in the 37 direction, the tonneau cover body 25 is wound around the winding means 21, and the drawer end 26 is pulled toward the winding means 21. The first slider 33 holding the drawer end 26 slides on the slide rail in the winding direction of the tonneau cover body 25, that is, in the direction of the winding means 21. Therefore, the tonneau cover body 25 is removed from the upper surface of the luggage room 28 and the luggage room 28 is opened.

  When the back door 30 is closed, as shown in FIG. 5, the connecting means 41 held by the back door 30 moves downward while contracting. Then, the second slider 38 held by the connecting means 41 slides downward on the second slide rail 35 and is away from the extension end 37 of the first slide rail 31, that is, the second slide rail 35. It is arranged on the lower end side. Due to the sliding movement of the second slider 38, the connecting tool 48 that connects the first slider 33 and the second slider 38 is pulled downward, and the first slider 33 moves in the direction of the extended end 37 of the first slide rail 31. Move to slide. Therefore, the drawer end portion 26 of the tonneau cover body 25 held by the first slider 33 is also pulled in the pulling direction which is the direction of the extended end 37 of the first slide rail 31, and the tonneau cover body 25 is pulled out. When the tonneau cover body 25 is pulled out, the upper surface of the luggage room 28 is covered with the tonneau cover body 25 and the luggage room 28 is closed.

  Therefore, according to the tonneau cover device 20 of the present embodiment, since the tonneau cover body 25 opens and closes in conjunction with the opening and closing of the back door 30, it is not necessary to manually open and close the tonneau cover body 25 and no complicated operation is required. .

  Further, in the tonneau cover device 20 of the present embodiment, the second slider 38 and the first slider 33 are slid by the opening and closing of the back door 30, and the tonneau cover body 25 is opened and closed. For this reason, since the tonneau cover device 20 is configured with a simple structure and does not require complicatedly wired wires or the like, problems such as tangling of wires do not occur unlike the conventional tonneau cover device 20. Further, when the back door 30 is closed, the connecting means 41 is moved by the displacement of the back door 30 and the second slider 38 is forcibly slid. Therefore, the portion of the tonneau cover device 20 disposed near the back door 30 is used. The connecting tool 48 is not sandwiched between the back doors 30. As a result, the tonneau cover device 20 does not break down due to the opening / closing of the back door 30.

  Further, since the connecting means 41 is extendable and retractable, the back door 30 is greatly opened even if the arrangement length of the second slide rail 35 is short. Therefore, for example, it can be installed in a vehicle having a shallow luggage room 28.

  Further, since the connecting means 41 is swingable with respect to both the back door 30 and the second slider 38, the arrangement direction of the second slide rail 35 with respect to the back door 30 can be set to a desired direction. .

  In addition, in the vehicle in which the tonneau cover device 20 of this embodiment is disposed, the back door 30 is opened and closed in the vertical direction. . In this case, the second slide rail may be disposed so as to extend in the left-right direction, and the second slider may be slid in the left-right direction.

  Further, in order to reduce an impact applied to the tonneau cover device 20 when the back door 30 is opened and closed, the connecting means 41 may be gently expanded and contracted. In this case, for example, by providing a damper means between the first rod 42 and the second rod 43, the second rod 43 gently enters and exits the inside of the cylinder of the first rod 42, and the connecting means 41 becomes loose. Will expand and contract.

  In addition, by adjusting the expansion / contraction speed and the like of the connecting means 41 by this damper means, the size of the back door 30 opening and the pull-out amount of the tonneau cover body 25 can be set as appropriate.

  For example, when the back door 30 is opened, the second slider 38 first slides and the connecting means 41 extends after the sliding movement of the second slider 38 is completed. Since the main body 25 is wound up and the upper surface of the luggage room 28 is opened, luggage can be accommodated in the luggage room 28 without fully opening the back door 30.

  Further, when the connecting means 41 that gently expands and contracts is used, the connecting means 41 may be used as a damper interposed between the back door 30 and the vehicle body in order to gently open and close the back door 30. it can.

(Example 2)
The tonneau cover apparatus according to the second embodiment is disposed in a vehicle having a shallow and wide luggage room. The first slide rail is longer and the second slide rail is shorter than the tonneau cover apparatus according to the first embodiment. This embodiment is the same as that of the first embodiment except that the connector includes the first connector, the second connector, and the connector winding means. FIG. 6 shows a perspective view schematically showing the connecting tool in the tonneau cover apparatus of the second embodiment, and FIGS. 7 and 8 show sectional views schematically showing the tonneau cover apparatus of the second embodiment.

  As shown in FIG. 6, the connecting tool 52 of the tonneau cover device 51 of the present embodiment includes a connecting tool winding means 53, and a first connecting tool 55 and a second connecting tool 56 made of metal wires. . Among these, as shown in FIGS. 7 and 8, the connector winding means 53 is rotatably supported in a communication hole 57 provided in the rear portion of the vehicle body.

  The connector winding means 53 includes a large-diameter columnar first winding part 58 and a disk-like second winding part 60 having a smaller diameter than the first winding part 58. The first winding part 58 and the second winding part 60 are connected to rotate coaxially. One end of the first connector 55 is held on the outer peripheral surface of the first winding part 58, and one end of the second connector 56 is held on the outer peripheral surface of the second winding part 60. The other end of the first connector 55 is fixed to the first slider 61, and the other end of the second connector 56 is fixed to the second slider 62. Further, the first connector 55 is wound around the first winding part 58 when the connector winding means 53 rotates in the direction of arrow a. And the 2nd connection tool 56 is wound by the 2nd winding part 60, when the connection tool winding means 53 rotates in the arrow b direction. The first winding portion 58 and the second winding portion 60 are provided with stopper portions 63 raised in the circumferential direction at two end portions in the axial direction. The stopper portion 63 functions as a stopper for preventing the first connector 55 and the second connector 56 wound around the first winding portion 58 and the second winding portion 60 from being detached in the axial direction.

  When the connector winding means 53 rotates in the direction of arrow a, the first connector 55 held by the first winding part 58 is wound around the outer peripheral surface of the first winding part 58. On the other hand, when the connector winding means 53 rotates in the direction of arrow a, the second connector 56 held by the second winding part 60 is unwound. Accordingly, at this time, the apparent length of the first connector 55 is shortened, and the apparent length of the second connector 56 is increased.

  When the connector winding means 53 rotates in the direction of arrow b, the second connector 56 held by the second winding part 60 is wound around the outer peripheral surface of the second winding part 60, and the first winding part 58. The first connector 55 held in the is extended. Accordingly, at this time, the apparent length of the second connector 56 is shortened, and the apparent length of the first connector 55 is increased. In this connection tool 52, the first winding part 58 and the second winding part 60 rotate coaxially, and the first winding part 58 has a larger diameter than the second winding part 60. The length of the first connector 55 that is wound or delivered by the first winding part 58 per rotation of the tool winding means 53 is the second connector 56 that is fed or wound by the second winding means. It is longer than the length of.

  The tonneau cover device 51 of the second embodiment operates as follows.

  During the opening operation of the back door 64, as shown in FIG. 7, the second slider 62 slides upward on the second slide rail 65 and the second connector 56 is loosened. Then, the tonneau cover main body 67 is wound up by the winding means 66, and the first slider 61 holding the drawer end portion 68 of the tonneau cover main body 67 slides in the winding direction. When the first slider 61 slides on the first slide rail 70, the first connector 55 fixed to the first slider 61 is pulled, so that the connector winding means 53 rotates in the arrow b direction, One connector 55 is fed out. Then, the second connector 56 is wound around the second winding part 60 by the rotation of the connector winding means 53.

  When the back door 64 is closed, as shown in FIG. 8, the second slider 62 slides downward on the second slide rail 65 and the second connector 56 is pulled. Therefore, the connector winding means 53 rotates in the direction of arrow a, and the second connector 56 is fed out. Further, since the first connector 55 is wound around the first winding portion 58 by the rotation of the connector winding means 53, the first slider 61 slides on the first slide rail 70 toward the extended end 71. . Then, the tonneau cover main body 67 is pulled out as the first slider 61 slides.

  Here, in the tonneau cover device 51 of the second embodiment, the first winding portion 58 and the second winding portion 60 rotate coaxially, and the first winding portion 58 is more than the second winding portion 60. It has a large diameter. For this reason, the length of the first connector 55 wound or fed by the first winding portion 58 per one rotation of the connector winding means 53 is the same as the length of the first connector 55 fed or wound by the second winding means. It is longer than the length of the two couplers 56. Therefore, even when the luggage room is shallow and has a large depth, and the sliding movement distance c of the first slider 61 is significantly longer than the sliding movement distance d of the second slider 62, the tonneau cover body 67 causes the entire upper surface of the luggage room to be Can be opened and closed.

The connecting tool 83 is made of a resin plate. When the second slider 86 slides in the direction of the extended end 87 of the first slide rail 76 during the opening operation of the back door 85, the first slider 82 is pressed against the connecting tool 83. Thus, the tonneau cover winding means 77 moves in the direction.

  Since the first slider 82 is connected to the second slider 86 by the connecting tool 83, the first slider 82 slides in the direction of the extended end 87 along with the closing operation of the back door 85 even if the drawer end 81 of the tonneau cover body 80 is removed. . For example, when the connector 83 is made of a relatively easily deformable material such as a wire, the first slider 82 remains disposed near the extended end 87 even when the back door 85 is opened, and the second slider 86. However, when the connecting member 83 is loosened by sliding toward the extended end 87 of the first slider 82, the connecting member 83 may protrude into the gap between the first slide rail 76 and the second slide rail 88. At this time, when the closing operation of the back door 85 is performed again, the protruding connector 83 may interfere with the closing operation of the back door 85 or may be sandwiched between the back door 85 and the vehicle body.

  Although this problem can be avoided by providing the slider moving means as described above, in the tonneau cover device 75 of this embodiment, the connecting tool 83 is made of a resin plate, and the connecting tool 83 itself serves as the slider moving means. Further, it is not necessary to provide a separate slider moving means.

  That is, in the tonneau cover device 75 of the present embodiment, the connecting tool 83 is made of a resin plate, and the first slider 82 is pressed when the second slider 86 slides during the opening operation of the back door 85. Even when the drawer end 81 is removed, the first slider 82 is slid along with opening and closing. Therefore, there is no problem that the above-described connecting tool 83 interferes with the closing operation of the back door 85 or is sandwiched between the back door 85 and the vehicle body.

  According to the tonneau cover device 75 of the third embodiment, in addition to the effect of the tonneau cover device of the first embodiment, the drawer end 81 is detachably held by the first slider 82, so that the back door 85 is closed. In addition, the upper surface of the luggage room 90 can be opened. For this reason, even a large luggage or the like can be accommodated in the luggage room 90 without being interfered with the tonneau cover main body 80. Further, since the connection tool 83 is made of a resin plate and the connection tool 83 functions as a slider moving means, the connection tool 83 interferes with the closing operation of the back door 85 or the back door 85 without providing a separate slider movement means. And the like can be avoided.
