The latch 26 that locks the rear door 10 has a latch sensor 27 that detects the latched state and outputs it to the ECU 51, and locks or releases the rear door 10 according to the control of the ECU 51.

  The ECU 51 includes, for example, a CPU (Central Processing Unit) 51a, semiconductor memories 51b and 51c, a timer circuit 51d, an I / O (input / output) circuit 51e, and the like connected to each other so as to be able to input and output information. When a program 51p including a shielding sheet driving program for realizing the shielding sheet driving function in a computer is written in a ROM (Read Only Memory) 51b, the ROM 51b is a computer-readable recording medium that records the shielding sheet driving program. Of course, the recording medium for the shielding sheet driving program may be an external recording medium read by the ECU, such as a magnetic disk. The CPU 51a executes a program 51p while using a RAM (Random Access Memory) 51c as a work area, and controls the entire operation of the tonneau cover device 3.

  The ECU 51 includes a door drive motor 21, an electromagnetic clutch 22, an angle sensor 24, a latch 26, a latch sensor 27, a warning buzzer 28, a warning light 29, switches 52a, 52c, 52e, 52f, 52g, a receiving unit 53, and a tonneau cover drive. Motor 82, etc. are connected. The warning buzzer 28 and the warning light 29 are installed on the instrument panel of the automobile 1. The warning buzzer 28 outputs a warning sound to the passenger compartment in accordance with a command from the ECU 51. The warning lamp 29 is turned on according to a command from the ECU 51. The opening switch 52a, the closing switch 52c, the tonneau cover accommodation command switch 52f, and the tonneau cover drawing command switch 52g are push button switches provided in the interior material near the driver's seat, and a voltage signal corresponding to the presence or absence of the pushing operation is sent to the ECU 51. Output to. The close switch 52e is provided on the surface of the rear door 10 on the cargo compartment LR1 side, and outputs a voltage signal to the ECU 51 according to whether or not a push operation is performed. The receiving unit 53 receives a radio signal corresponding to whether or not the opening switch 52b and the closing switch 52d are pressed from the ignition key 5, and outputs a voltage signal corresponding to the radio signal to the ECU 51. The tonneau cover driving motor 82 operates to take in and out the tonneau cover 30 with respect to the winding device 40 under the control of the ECU 51.

  The ECU 51 inputs signals according to whether or not the switches 52a to 52g are pressed, and inputs the detection signals of the angle sensor 24 and the latch sensor 27, while the door drive motor 21, the electromagnetic clutch 22, the warning buzzer 28, and the warning. The operation of the lamp 29 and the tonneau cover driving motor 82 is controlled.

  By the way, when the tonneau cover 30 is accommodated, the bent portions FP1 and FP2 come close to each other along the intermediate member 64. Therefore, a large gap is formed between the bent portions FP1 and FP2 and the end portions 64a and 64b of the intermediate member. Occurs. If the support members 61A and 61B always restrict the movement of the intermediate member 64 in the width direction D3, the intermediate member 64 does not shift in the width direction D3. For example, as shown in FIG. If both sides of D3 are curved, the movement of the intermediate member 64 in the width direction D3 may not be restricted by the support members 61A and 61B. As shown in FIG. 12 (a), the intermediate members 61a and 61b facing the end portions 64a and 64b of the intermediate member are supported with the end portions 64a and 64b of the intermediate member at a relatively wide portion between the inner side surfaces 61f and 61f. The distance X1 in the width direction D3 with the inner side surfaces 61f, 61f of the member is relatively large. On the other hand, as shown in FIG. 12 (b), in the location where the distance between the inner side surfaces 61f, 61f of the support member is relatively narrow, the width direction D3 between the end portions 64a, 64b of the intermediate member and the inner side surfaces 61f, 61f of the support member. Distance X2 is relatively small. Accordingly, when the intermediate member 64 is displaced in the width direction D3 at the location shown in FIG. 12A and slides to the location shown in FIG. 12B, the intermediate member 64 is narrowed between the inner surfaces 61f and 61f of the support member. 64 interferes with one inner surface 61f of the support member. In consideration of the possibility of abnormal noise, the dropping of the intermediate member 64 from the support members 61A and 61B, and the damage of the intermediate member 64, it is desirable that the intermediate member 64 does not interfere with the inner side surface 61f of the support member.

Further, as shown in FIG. 3, when the support portion of the intermediate member 64 is provided only in the rear region R1 of the cargo compartment in which the space between the deck side trims 6 and 6 is relatively narrow, the intermediate member is disposed in the region before the rear region R1. If 64 shifts in the width direction D3, there is a possibility that the intermediate member 64 does not ride on the support portion. Further, when the intermediate member 64 is displaced in the width direction D3 when the tonneau cover 30 is stored while the rear door 10 is opened, the intermediate member 64 interferes with the opening edge of the rear door 10 so that the tonneau cover 30 can be stored smoothly. It may not be possible.
Therefore, in the present embodiment, a centering mechanism (positioning mechanism) 100 is provided in the tonneau cover device 3.

As shown in FIGS. 5 and 6, the centering mechanism 100 is provided on the intermediate member 64 between the bent portions FP1 and FP2 of the arm mechanism. FIG. 13 shows the centering mechanism 100 and its periphery when viewed from above with the cover 160 removed from the intermediate member 64. Here, the pinion 130 is provided at the center of the intermediate member 64, that is, in the intermediate portion of the intermediate member 64 in the width direction D3, and the direction toward the pinion 130 along the width direction D3 is the inner direction D4 in the width direction and the width direction D3. A direction away from the pinion 130 along the width is defined as an outer direction D5 in the width direction.
The centering mechanism 100 includes a pair of racks 110 and 120, a pinion 130, and an urging means 140.

  The racks 110 and 120 are provided so that the teeth 111 and 121 arranged in the width direction D3 of the tonneau cover face each other and can move in the width direction D3 of the tonneau cover with respect to the intermediate member 64. The first rack 110 is a first bent portion 112 whose one end is bent toward the tooth tip (withdrawal direction D1), and is substantially L-shaped. The first bent portion FP1 contacts the outer portion 113 of the bent portion 112 when the arm mechanisms AR1 and AR1 are bent. The second rack 120 is a second bent portion 122 whose one end is bent toward the tooth tip (accommodating direction D2), and is substantially L-shaped. The bent portion 122 abuts on the second bent portion FP2 when the arm mechanisms AR1 and AR1 are bent. The racks 110 and 120 are inserted into the groove 65 of the intermediate member with the longitudinal direction thereof directed in the width direction D3 and are slidable in the width direction D3, and are regulated by the facing portion 65a as shown in FIG. It is made not to fall off. The racks 110 and 120 are arranged so as to be point-symmetric with respect to the center of the intermediate member 64 in a state where the racks 110 and 120 are engaged with the pinion 130.

  The pinion 130 is provided so as to be rotatable with respect to the intermediate member 64 while being engaged with both racks 110 and 120, and synchronizes the movement of the first rack 110 and the movement of the second rack 120 in opposite directions. As shown in the enlarged view of FIG. 13, the rotation shaft 131 of the pinion 130 faces the vertical direction perpendicular to the width direction D3 and perpendicular to the drawing direction D1. The teeth 132 of the pinion 130 mesh with the teeth 111 and 121 of both racks.

For example, as shown in FIG. 14, an opening is formed in the pinion 130 along the rotation shaft 131, an opening is also formed in the bottom portion 64c of the intermediate member 64 and the cover 160, and the retaining member 134 is formed outside the bottom portion 64c of the intermediate member. And the pinion 130 can be attached to the intermediate member 64 by screwing the screw 133 and the retaining member 134 through the opening. In this case, the screw 133 becomes the rotation shaft 131.
Note that the position of the pinion 130 with respect to the intermediate member 64 may be shifted from the intermediate position in the width direction D3. Further, the number of pinions 130 may be two or more.

When the bent portions FP1 and FP2 of the bent arm mechanisms AR1 and AR1 are in contact with the centering mechanism 100, the urging means 140 pushes the bent portions FP1 and FP2 to the inner side in the width direction D3 of the tonneau cover 30. The tonneau cover 30 is urged to the outside in the width direction D3. The biasing means 140 is attached to both racks 110 and 120. The urging means 140 of the present embodiment has urging members 141 and 142. The urging members 141 and 142 shown in FIG. 13 are shown in a state where no external force is applied, that is, in a state where the outside is not urged.
Springs such as coil springs can be used for the urging members 141 and 142. As the spring, a metal spring such as a stainless steel wire or a piano wire can be used, but a spring made of a resin material or the like may be used. Moreover, you may use non-metallic elastic members, such as a leaf | plate spring and rubber | gum, for a spring instead of a coil spring.

The first urging member 141 is interposed between the inner portion 114 of the first bent portion 112 and the end 125 of the second rack 120 opposite to the second bent portion 122. ing. Here, interposing means installing between members. That is, the outer end portion 141 a of the biasing member 141 is attached to the inner portion 114 of the first bent portion 112, and the inner end portion 141 b of the biasing member 141 is attached to the end portion 125 of the second rack 120. Yes. The inner part 114 of the first bent part 112 is a part on the opposite side of the first bent part 112 from the contact part (outer part 113) of the first bent part FP1.
The second urging member 142 is interposed between the inner portion 124 of the second bent portion 122 and the end 115 of the first rack 110 opposite to the first bent portion 112. Yes. That is, the outer end 142 a of the urging member 142 is attached to the inner part 124 of the second bent portion 122, and the inner end 142 b of the urging member 142 is attached to the end 115 of the first rack 110. Yes. The inner part 124 of the second bent part 122 is a part on the opposite side of the second bent part 122 from the contact part (outer part 123) of the second bent part FP2.

When the bent portions FP1 and FP2 are in contact with the bent portions 112 and 122 of the rack when the urging members 141 and 142 are pressed inward in the width direction D3 of the tonneau cover, the bent portions 112 and 122 become the width of the tonneau cover. Energize outward in the direction D3. That is, when the bent portions FP1 and FP2 push the bent portions 112 and 122 of the rack in the inner direction D4, the urging members 141 and 142 are compressed in the width direction D3, and the bent portions 112 and 122 are pushed in the outer direction D5. Energize.
As to how much the intermediate member 64 slides in the accommodation direction D2, the length of the racks 110 and 120 and the length of the biasing members 141 and 142 in the width direction D3 are changed. Can be adjusted.

One of the urging members 141 and 142 of the urging means 140 can be omitted. For example, if the second urging member 142 is omitted, the second bent portion 122 serves as an abutting portion according to the present invention, and the urging member 141 has the first bent portion FP1 abutted against the bent portion 112. When the second bent portion FP2 is in contact with the contact portion 122 and is pushed inward in the width direction D3 of the tonneau cover, the bent portion 112 and the contact portion 122 are urged outward in the width direction D3 of the tonneau cover. .
The urging members 141 and 142 are preferably the same urging force (spring constant or the like), but may be different urging forces.

  The cover 160 is a member that prevents the racks 110 and 120, the pinion 130, and the biasing means 140 from being exposed as much as possible. The cover 160 of the present embodiment is formed in a flat plate shape, screw insertion holes 164 through which the screws 168 pass are formed in the vicinity of the four corners, and screw insertion holes 166 through which the screws 133 pass through at the center. The intermediate member 64 is formed with screw holes for screwing screws 168 through the screw insertion holes 164.

The centering mechanism 100 can be provided on the intermediate member 64 as follows, for example.
First, in a state where at least one of the end holders 64a and 64b is not attached to the intermediate member 64, both racks 110 and 120 are inserted into the groove 65 of the intermediate member in the direction shown in FIG. Next, the pinion 130 is inserted into the attachment position with respect to the intermediate member 64 while arranging the racks 110 and 120 so as to be point-symmetric with respect to the center of the intermediate member 64. Further, the cover 160 is disposed at the attachment position with respect to the intermediate member 64, the retaining member 134 is disposed outside the bottom portion 64c of the intermediate member, and the screw 133 is inserted into the screw insertion hole 166 of the cover, the opening of the pinion 130, and the intermediate member bottom portion 64c. It passes through the opening and is screwed into the retaining member 134. Then, when the screw 168 is threaded into the intermediate member 64 through the screw insertion hole 164 of the cover, the attachment of the centering mechanism 100 to the intermediate member 64 is completed.

(2) Operation, action and effect of the tonneau cover device according to the first embodiment:
Hereinafter, operation | movement, an effect | action, and effect of the tonneau cover apparatus 3 of 1st embodiment are demonstrated.
When the rear door 10 is closed and the tonneau cover 30 is pulled out to the pull-out position LO2, when the tonneau cover command switch 52f shown in FIG. 11 is pushed, the ECU 51 moves the tonneau cover 30 in the storing direction D2. The motor 82 is driven to rotate. At this time, the link members 84A and 84B move outward in the width direction D3, and the movement of the link member causes the arm mechanisms AR1 and AR1 to bend inward in the width direction D3 at the bent portions FP1 and FP2 in a substantially horizontal plane. As a result of the bending of the arm mechanism, the intermediate member 64 and the tip member 63 move along the support members 61A and 61B in the accommodation direction D2, and the tonneau cover 30 is wound around the winding device 40 by the biasing force of the spring 42.

  FIG. 15 schematically shows the operation of the tonneau cover device 3 when the tonneau cover 30 is accommodated. When the tonneau cover 30 is in the pull-out position LO2, as shown in FIG. 15A, the bent portions FP1 and FP2 are located close to the end portions 64a and 64b of the intermediate member. As the arm mechanisms AR1 and AR1 bend, the bent portions FP1 and FP2 approach each other. Here, when the intermediate member 64 is located at a relatively wide portion between the inner side surfaces 61f and 61f of the support member, the intermediate member 64 is displaced in either one of the width directions D3 as shown in FIG. 15B. Sometimes. In the example of FIG. 15B, the intermediate member 64 is shifted to the left side and the second bent portion FP2 is separated from the second bent portion 122, while the first bent portion FP1 is the first bent portion. It is shown in contact with the portion 112.

  Further, even if the arm mechanisms AR1 and AR1 are bent and a pressing force is applied from the first bent portion FP1 to the first bent portion 112, the centering mechanism 100 moves the intermediate member 64 toward the second bent portion FP2. Will be allowed to. Here, since the urging means 140 is attached to the racks 110 and 120, the impact when the bent portions FP1 and FP2 come into contact with the bent portions 112 and 122 is reduced. And the 2nd bending part 122 and 2nd bending part FP2 which move toward the 2nd bending part FP2 contact | abut. Here, both racks 110 and 120 are arranged point-symmetrically with respect to the center of the intermediate member 64, and a point-symmetrical relationship is maintained by the meshed pinion 130, so that the intermediate member 64 is centered in the width direction D3. (Predetermined position) Positioned at LC1.

  After that, as shown in FIG. 15 (c), when the bent portions FP1, FP2 push the bent portions 112, 122 in the inner direction D4 in the width direction, the urging members 141, 142 are compressed in the width direction D3, The bent portions FP1 and FP2 are urged to the outer side direction D5 in the width direction through the bent portions 112 and 122. Thereby, the contact state between the bent portions FP1 and FP2 and the bent portions 112 and 122 is maintained. Since the racks 110 and 120 move synchronously in opposite directions, the intermediate member 64 moves in the accommodation direction D2 while being centered without being shifted in the width direction D3. Accordingly, the intermediate member 64 is prevented from falling off from the support members 61A and 61B. 3 and 4, even if the space between the inner side surfaces 61f and 61f of the support member is relatively narrow at a position close to the winding device 40, the intermediate member 64 interferes with the inner side surface 61f of the support member. Is suppressed.

As shown in FIG. 15D, when the arm mechanisms AR1 and AR1 are folded and the tonneau cover 30 is accommodated up to the accommodation position LO1, the intermediate member 64 is centered in the width direction D3. Therefore, the intermediate member 64 does not hinder the accommodation of the tonneau cover 30, and the tonneau cover 30 is accommodated smoothly.
As described above, since the tonneau cover device 3 includes the intermediate member 64, even if a load is applied to the arm mechanisms AR1 and AR1, the load is distributed and applied to the intermediate member 64, and the arm mechanisms AR1 and AR1. Is difficult to deform. Further, when the tonneau cover 30 is accommodated, the intermediate member 64 is positioned at a predetermined position in the width direction D3 of the tonneau cover, and displacement in the width direction D3 is suppressed. Therefore, according to the present tonneau cover device 3, it is possible to reduce the deformation of the arm mechanism due to the load being applied and to accommodate the tonneau cover smoothly.
In addition, since the centering mechanism 100 can be expanded and contracted in the width direction D3 and is urged toward the outside, the centering mechanism 100 is biased to the outside in the width direction D3, so that it is possible to absorb variations in the distance between the bent portions FP1 and FP2.

  When the rear door 10 is closed and the tonneau cover 30 is accommodated in the accommodation position LO1, when the pushing operation is performed on the tonneau cover withdrawal command switch 52g shown in FIG. 11, the ECU 51 moves the tonneau cover 30 in the withdrawal direction D1. The motor 82 is driven to rotate in the direction to be driven. At this time, the link members 84A and 84B move inward in the width direction D3, the bent portions FP1 and FP2 extend, the intermediate member 64 and the tip member 63 move in the drawing direction D1 along the support members 61A and 61B, and the tonneau cover 30 is withdrawn from the winding device 40. Here, when the arm mechanisms AR1 and AR1 are folded, the urging means 140 urges the bent portions FP1 and FP2 in the outer side direction D5 in the width direction, so that the driving force of the motor 82 when pulling out the tonneau cover 30 is increased. Less is enough.

(3) Second embodiment:
16 and 17 show the main part of the tonneau cover device 3 according to the second embodiment. The centering mechanism (positioning mechanism) 101 of this embodiment includes a pair of racks 110 and 120, a plurality of pinions 130, a biasing means 140, and contact members 151 and 152.
The first rack 110 is a first bent portion 112 whose one end is bent toward the tooth tip and the other end is a first rack abutting portion 116 that abuts the second bent portion FP2. .
The second rack 120 is a second bent portion 122 whose one end is bent toward the tooth tip and the other end is a second rack abutting portion 126 that abuts the first bent portion FP1. .
The first bent portion 112 is disposed on the inner side in the width direction D3 than the second rack contact portion 126.
The second bent portion 122 is disposed on the inner side in the width direction D3 than the first rack contact portion 116.
The racks 110 and 120 are arranged so as to be point-symmetric with respect to the center of the intermediate member 64, and move in synchronization in opposite directions by a plurality of pinions 130 meshed together.

The first contact member 151 is disposed outside the first bent portion 112 in the width direction D3 and further inside the width direction D3 than the second rack contact portion 126, and has arm mechanisms AR1, AR1. Is bent, the first bent portion FP1 contacts.
The second contact member is disposed on the outer side in the width direction D3 than the second bent portion 122 and on the inner side in the width direction D3 than the first rack contact portion 116, and the arm mechanisms AR1 and AR1 are When bent, the second bent portion FP2 comes into contact.
Both abutting members 151 and 152 are inserted into the groove 65 of the intermediate member so as to be slidable in the width direction D3 so that they do not fall off from the intermediate member 64.

The first urging member 141 of this embodiment is interposed between the first contact member 151 and the outer portion 113 of the first bent portion 112. That is, the outer end 141 a of the biasing member 141 is attached to the first contact member 151, and the inner end 141 b of the biasing member 141 is attached to the outer portion 113 of the first bent portion 112.
The second urging member 142 is interposed between the second contact member 152 and the outer portion 123 of the second bent portion 122. That is, the outer end 142 a of the urging member 142 is attached to the second contact member 152, and the inner end 142 b of the urging member 142 is attached to the outer portion 123 of the second bent portion 122.
Springs such as coil springs can be used for the urging members 141 and 142.

  When the bent portions FP1, FP2 are in contact with the contact members 151, 152 when the urging members 141, 142 are pushed inward in the width direction D3 of the tonneau cover, the contact members 151, 152 are moved in the width direction D3 of the tonneau cover. Energize outside. The urging members 141 and 142 are preferably set to the same urging force from the viewpoint of centering the intermediate member 64, but may be different from the viewpoint of positioning the intermediate member 64 at a predetermined position.

  FIG. 18 schematically shows the operation of the tonneau cover device 3 when the tonneau cover 30 is accommodated. When the tonneau cover 30 is in the pull-out position LO2, the bent portions FP1 and FP2 are separated from the rack contact portions 116 and 126. As the arm mechanisms AR1 and AR1 are bent, the bent portions FP1 and FP2 come into contact with the rack contact portions 116 and 126 as shown in FIG. Here, if the intermediate member 64 is displaced in any one of the width directions D3, a difference occurs in the time during which the bent portions FP1, FP2 and the rack contact portions 116, 126 contact each other. At this stage, since the urging force from the urging means 140 is not applied to the bent portion, the displacement of the intermediate member 64 in the width direction D3 may not be eliminated.

  As shown in FIG. 18B, when the bent portions FP1 and FP2 come into contact with the contact members 151 and 152, the urging members 141 and 142 thereafter move the contact members 151 and 152 in the outer side direction D5 in the width direction. Energize. Here, even if the intermediate member 64 is displaced in the width direction D3 and a pressing force is applied from one bent portion to the one abutting member, the centering mechanism 101 moves the intermediate member 64 toward the other bent portion. Become. Since the racks 110 and 120 maintain a point-symmetric relationship, the intermediate member 64 is positioned at the predetermined position LC1 in the width direction D3.

Thereafter, as shown in FIG. 18C, when the bent portions FP1 and FP2 push the rack contact portions 116 and 126 and the contact members 151 and 152 in the inner direction D4 in the width direction, the urging members 141 and 142 are moved. , Compressed in the width direction D3, and urges the bent portions FP1, FP2 to the outer side direction D5 in the width direction via the rack contact portions 116, 126 and the contact members 151, 152. Thereby, the intermediate member 64 moves to the accommodation direction D2 with the positioning state maintained.
As described above, also in this embodiment, it is possible to reduce the deformation of the arm mechanism due to the application of a load and to accommodate the tonneau cover smoothly.

(4) Third embodiment:
FIG. 19 shows a main part of the tonneau cover device 3 according to the third embodiment. The centering mechanism (positioning mechanism) 102 of this embodiment is configured by replacing the contact members 151 and 152 with fixing members (fixing portions) 153 and 154 from the centering mechanism 101 of the second embodiment.
The first fixing member (first fixing portion) 153 is disposed outside the first bent portion 112 in the width direction D3 and further inside the width direction D3 than the second rack contact portion 126. The intermediate member 64 is attached and fixed.
The second fixing member (second fixing portion) 154 is disposed outside the second bent portion 122 in the width direction D3 and further inside than the first rack contact portion 116 in the width direction D3. The intermediate member 64 is attached and fixed.
Both the fixing members 153 and 154 are provided in the groove 65 of the intermediate member at positions that are point-symmetric with respect to the center of the intermediate member 64.
Note that the fixing portions 153 and 154 may not be members different from the intermediate member 64, and may be portions constituting the intermediate member 64.

The first urging member 141 of this embodiment is interposed between the first fixing member 153 and the outer portion 113 of the first bent portion 112. The second urging member 142 is interposed between the second fixing member 154 and the outer portion 123 of the second bent portion 122.
The urging members 141 and 142 have their end portions 141b and 142b on the bent portions FP1 and FP2 side pushed toward the outer side direction D5 in the width direction when the bent portions FP1 and FP2 are in contact with the rack contact portions 116 and 126. Then, the bent portions FP1 and FP2 are biased in the inner direction D4 in the width direction.

  As shown in FIG. 19A, when the arm mechanisms AR1 and AR1 are bent and the bent portions FP1 and FP2 are brought into contact with the rack contact portions 116 and 126, the first biasing member 141 is thereafter moved to the first biasing member 141. The rack 110 is biased to the right, and the second biasing member 142 biases the second rack 120 to the left. Accordingly, the bent portions FP1 and FP2 are biased in the outer side direction D5 in the width direction. Here, even if the intermediate member 64 is displaced in the width direction D3 and a pressing force is applied from one bent portion to one rack contact portion, the centering mechanism 102 moves the intermediate member 64 toward the other bent portion. It becomes. Since the racks 110 and 120 maintain a point-symmetric relationship, the intermediate member 64 is positioned at the predetermined position LC1 in the width direction D3.

After that, as shown in FIG. 19B, when both bent portions FP1 and FP2 push the rack contact portions 116 and 126 in the inner direction D4 in the width direction, the urging members 141 and 142 are compressed in the width direction D3. The bent portions FP1 and FP2 are biased in the outer side direction D5 in the width direction via the racks 110 and 120 that move in opposite directions in synchronization with each other. Thereby, the intermediate member 64 moves to the accommodation direction D2 with the positioning state maintained.
As described above, also in this embodiment, it is possible to reduce the deformation of the arm mechanism due to the application of a load and to accommodate the tonneau cover smoothly.

(5) Fourth embodiment:
FIG. 20 shows a main part of the tonneau cover device 3 according to the fourth embodiment. The centering mechanism (positioning mechanism) 103 according to the present embodiment includes a fixing member (fixing portion) 155, an urging means 140, and contact members 151 and 152.
The fixing member 155 is a member for attaching the urging means 140 and is attached and fixed to the center of the intermediate member 64.
Note that the fixing portion 155 may not be a member different from the intermediate member 64, and may be a part constituting the intermediate member 64.

The first and second contact members 151 and 152 are disposed outside the fixed portion 155 in the width direction D3, and the bent portions FP1 and FP2 contact each other when the arm mechanisms AR1 and AR1 are bent.
The first urging member 141 of this embodiment is interposed between the first contact member 151 and the fixed portion 155. The second urging member 142 is interposed between the second contact member 152 and the fixed portion 155. The biasing members 141 and 142 are provided symmetrically with respect to the center of the intermediate member 64.
Springs such as coil springs can be used for the urging members 141 and 142.

  When the bent portions FP1, FP2 are in contact with the contact members 151, 152 when the urging members 141, 142 are pushed inward in the width direction D3 of the tonneau cover, the contact members 151, 152 are moved in the width direction D3 of the tonneau cover. Energize outside. The urging members 141 and 142 are preferably set to the same urging force from the viewpoint of centering the intermediate member 64, but may be different from the viewpoint of positioning the intermediate member 64 at a predetermined position.

When the arm mechanisms AR1 and AR1 bend, even if the intermediate member 64 is displaced in the width direction D3 and a force is applied from one bent portion to one abutting member, the centering mechanism 103 causes the intermediate member 64 to move to the other bent portion. It will be moved towards. Since the urging members 141 and 142 are provided symmetrically with respect to the center of the intermediate member 64, the intermediate member 64 moves in the accommodation direction D2 while being positioned at a predetermined position in the width direction D3.
As described above, also in this embodiment, it is possible to reduce the deformation of the arm mechanism due to the application of a load and to accommodate the tonneau cover smoothly.

(6) Fifth embodiment:
FIGS. 21-23 has shown the principal part of the tonneau cover apparatus 3 which concerns on 5th embodiment. The tonneau cover device 3 of this embodiment includes the centering mechanism 100 of the first embodiment, and accommodates the tonneau cover 30 when the rear door 10 is opened, and pulls out the tonneau cover 30 when the rear door 10 is closed. Here, if the accommodation operation of the tonneau cover 30 and the opening operation of the rear door 10 are started at the same time, the intermediate member 64 may be shifted in the width direction D3 when it is separated from the support member 61. The possibility that the intermediate member 64 may come into contact with the side wall of the cargo compartment, the possibility that the tonneau cover 30 cannot be stored smoothly due to interference with the opening edge of the rear door 10 when the tonneau cover 30 is retracted, and what the intermediate member 64 is outside the vehicle. In consideration of the possibility of contact with the crab, it is desirable that the opening operation of the rear door 10 is started after the tonneau cover 30 is accommodated to some extent. On the other hand, when the rear door 10 is opened after the accommodation of the tonneau cover 30 is completed, it may be felt that it takes a long time to complete the opening operation of the rear door 10.
Therefore, in this embodiment, the tonneau cover 30 is accommodated to some extent before the opening operation of the rear door 10 is started.

The automobile 1 of the present embodiment waits for a predetermined time (T ₁ second) after receiving the first operation for opening the rear door (loading door) 10 under the control of the ECU 51, and then the rear door in the closed state. The drive which opens 10 is started. In addition, the automobile 1 is driven to close the rear door 10 when receiving a second operation for closing the rear door 10 under the control of the ECU 51. Here, in order to ensure safety when opening the rear door, the automobile 1 outputs a warning sound for a predetermined time (for example, 1 second) after receiving a switch operation for opening the rear door 10 and then closes the rear door 10. Start driving to open.

If the rear door 10 is opened when the tonneau cover 30 is pulled out to some extent, the tip member 63 and the support member 61 may interfere with each other. Therefore, in this embodiment, hinges 68A and 68B are provided at the bent portions FP1 and FP2.
The hinge 68 connects the first arm member 67 and the second arm member 69 to each other along the tonneau cover 30 so as to be rotatable. Further, the hinge 68 connects both the arm members 67 and 69 so that they can be bent in a direction protruding downward. Therefore, the second arm member 69 has a direction in which the end portion 69c on the winding device (accommodating device) 40 side is rotatable with respect to the end portion 67a on the distal end side of the first arm member and protrudes downward. It is connected so that it can be bent. In FIG. 23, an example of the bending position of the second arm member 69 with respect to the first arm member 67 is indicated by a two-dot chain line.
Note that the left and right hinges 68A and 68B are not bent in a direction that protrudes upward, but are bent in a direction that protrudes only downward.

The distal ends of the arm members 67A and 67B have connection portions 67b and 67b that are rotatably connected to the hinges 68A and 68B. Specifically, the end portion 67a on the distal end side of the arm member 67, the hinge 68, and the runner member RU1 are connected by a rivet RI2 via washers WA2 and WA3 so as to be rotatable about the axial direction of the rivet RI2. Yes.
The second arm member 69 has a connecting portion 69d attached to the hinge 68 so as to be rotatable at an end portion 69c on the winding device 40 side. The end portions 69c and 69c of the arm members 69A and 69B on the winding device 40 side and the hinges 68A and 68B are connected by washers WA4 and WA5 to be rotatable around the axial direction of the rivet RI3 by the rivet RI3. ing.
Here, the bent portion includes a hinge 68, a runner member RU1, washers WA2 to WA5, and rivets RI2 and RI3.

FIG. 24 is a flowchart illustrating an example of the driving process of the rear door 10 and the tonneau cover 30 performed by the ECU 51. This driving process is repeatedly performed by the CPU 51a. Here, steps S102 to S106, S110 to S112, and S118 to S134 correspond to the opening / closing control processing of the rear door 10, and steps S108, S114 to S116, and S136 to S140 are the tonneau cover driving means (shielding sheet driving means) 50. It corresponds. Hereinafter, the description of “step” is omitted.
The waiting time T ₁ until the rear door 10 starts to open is 1 second, the time T _op for the rear door 10 to open from the fully closed position LO3 to the fully open position LO4 is 6 seconds, and the rear door 10 starts to close. The waiting time T ₂ until the closing is 1 second, the time T _cl when the rear door 10 is closed from the fully open position LO4 to the fully closed position LO3 is 6 seconds, and the time T _re when the tonneau cover 30 is moved from the drawer position LO2 to the housing position LO1 is 4 The time T _pu for moving the tonneau cover 30 from the accommodation position LO1 to the extraction position LO2 is 4 seconds. Moving time T _re in the accommodating direction D2 of the tonneau cover, so that to accommodate the tonneau cover 30 in the middle of the rear door 10 is open is complete, is less than T ₁ + T _op.

  First, it is assumed that the rear door 10 is closed and the tonneau cover 30 is in the drawer position LO2. When the process is started, the ECU 51 determines whether or not the open switches 52a and 52b are pressed for a predetermined period (for example, for a long time for one second) (S102). When the condition is satisfied, the ECU determines whether or not the rear door 10 is closed in S104 (for example, a signal that detects that the rear door 10 is in the fully closed position is input from the angle sensor 24). The ECU performs a process (not shown) when the rear door is not closed and ends the driving process, and starts a warning process for ensuring safety when the rear door is closed (S106). In this warning process, for example, the warning buzzer 28 outputs a warning sound to the passenger compartment, and the warning lamp 29 is turned on. Thereafter, the ECU causes the motor 82 to start rotational driving in a direction in which the tonneau cover 30 that has been pulled out is moved in the accommodation direction D2 (S108). At this time, the link members 84A and 84B move outward in the width direction D3, the arm mechanisms AR1 and AR1 bend inward in the width direction D3, and the intermediate member 64 and the tip member 63 move in the accommodation direction D2. The tonneau cover 30 is wound around the winding device 40.

After waiting for T ₁ second in S110, the ECU ends the warning process in S112 and causes the door opening / closing device 20 to start driving to open the rear door 10. FIG. 26 shows the state of the automobile 1 at the timing t1 immediately before the rear door 10 is opened.
When driving to open the rear door 10 is started, the ECU determines whether or not the accommodation of the tonneau cover 30 is completed in S114, and repeats the process of S114 until the accommodation of the tonneau cover 30 is completed. This process can be a moving time T _re processing the ECU determines whether or not elapsed in the accommodating direction from the start of receiving of the tonneau cover, the winding completion from the sensor for detecting the winding completion tonneau cover Processing in which the ECU determines whether a detection signal has been input may be performed.

As shown in FIG. 27, when the rear door 10 is opened while the tonneau cover 30 is wound up, the intermediate member 64 is detached from the support member detachment permission portion 61b, and the tip member 63 is placed on the detachment permission portion 61b. Thus, the first arm member 67 is in a state where the front end side is lower than the rear end side. Here, since the arm mechanisms AR1 and AR1 are bent halfway, both the bent portions FP1 and FP2 are already in contact with the centering mechanism 100 (the state shown in FIG. 15C), or both bent soon. The parts FP1 and FP2 are in contact with the centering mechanism 100. Therefore, even if the intermediate member 64 is detached from the separation permission portion 61b, the shift in the width direction D3 is reduced. Of course, if the two bent portions FP1 and FP2 contact the centering mechanism 100, the intermediate member 64 is positioned at the centering position (predetermined position) LC1 in the width direction D3.
If the distance between the bent portions FP1 and FP2 when the intermediate member 64 is detached from the separation permission portion 61b is set to be substantially the same as the length in the width direction D3 of the centering mechanism 100 when no force is applied, the intermediate member 64 is kept approximately at the centering position LC1. In particular, when the length in the width direction D3 of the centering mechanism 100 is set such that the intermediate member 64 is detached from the separation permission portion 61b after both the bent portions FP1 and FP2 are in contact with the centering mechanism 100, the intermediate member 64 is always This is preferable because it is positioned at a predetermined position LC1 in the width direction D3.

FIG. 25 (a) shows changes over time in the drawer amount of the tonneau cover 30 and the opening amount of the rear door 10 when the time when the opening switch is operated is time t = 0 seconds. Here, the pull-out amount of the tonneau cover is a relative amount with the accommodation position LO1 being 0% and the pull-out position LO2 being 100%. The opening amount of the rear door is a relative amount where the fully closed position LO3 is 0% and the fully open position LO4 is 100%. As shown in FIG. 6 (a), tonneau cover 30 is wound up during the waiting time T ₁ is started, winding upon opening of the rear door of approximately 50% has ended. FIG. 28 shows that the tonneau cover 30 is wound around the winding device 40 at a timing t2 when the rear door 10 is open.

When the winding of the tonneau cover 30 is completed, the ECU stops the rotation drive of the motor 82 that moves the tonneau cover 30 in S116, and whether the rear door 10 is in the fully open position LO4 in S118 (for example, the rear door 10 is in the fully open position). Whether or not a signal for detecting this is input from the angle sensor 24) is determined, and the process of S118 is repeated until the rear door 10 reaches the fully open position LO4. As shown in FIG. 28, when the rear door 10 reaches the fully open position LO4 at timing t3, the ECU stops the driving of the door opening / closing device 20 in S120 and ends the driving process.
As described above, when the tonneau cover device 3 receives an operation for opening the rear door, the tonneau cover 3 waits until the rear door 10 starts to drive toward the housing position LO1 with respect to the tonneau cover 30 being pulled out. The tonneau cover 30 is driven so as to end the accommodation in the winding device 40 after the rear door 10 starts to open.

  On the other hand, when the rear door 10 is in the fully open position LO4 and the tonneau cover 30 is in the storage position LO1, if the ECU 51 determines in S102 that the open switch has not been pressed for a long time, the close switches 52c to 52e have been pressed for a predetermined period. It is determined whether or not (S122). When the condition is satisfied, the ECU controls the tonneau cover 30 accommodated in the winding device 40 provided in the opened rear door 10 to be driven after the rear door 10 is closed and pulled out from the winding device 40 ( S124 to S140). Then, as shown in FIG.25 (b), the tonneau cover 30 is pulled out when the opening amount of the rear door 10 becomes 0%.

As described above, since the standby time T ₁ of the after operation to open the rear door is accepted until the driving of the rear door is started is used for the tonneau cover housing, detached from detachment permission section 61b The shift of the intermediate member 64 in the width direction D3 is small. Therefore, the tonneau cover device 3 of the present embodiment does not take much time when the rear door is opened, and it is possible to prevent the tonneau cover from getting in the way when loading and unloading the luggage, and by applying a load. It is possible to reduce the deformation of the arm mechanism and accommodate the tonneau cover smoothly.

In the fifth embodiment, the hinge mechanism for connecting the first and second arm members so as to be bent in a downward convex direction is not limited to a separate member such as a hinge. It may be formed on a part of the second arm member, or may be formed on a part of the second arm member.
In the fifth embodiment, the arm mechanisms AR1 and AR1 may be formed of a material capable of bending. In this case, even if there is no hinge mechanism such as the hinge 68, the arm members 67 and 69 are bent so as to protrude downward as shown in FIG. 29, so that the tonneau cover 30 is opened while the rear door 10 is opened. Can be accommodated.

(7) Modification:
The present invention can be modified in various ways.
For example, the luggage compartment door may be a door that is disposed on the side of the luggage compartment and opens sideways. In this case, the pulling-out direction and the accommodation direction of the tonneau cover may be the left-right direction of the automobile.
The tonneau cover device may be a folding device that accommodates the bellows-like tonneau cover in a retractable manner with respect to the accommodating device.
The drawing direction of the shielding sheet may be a direction deviated from the horizontal in addition to being substantially horizontal.
The various embodiments described above can also be applied to blind devices that shield windows such as rear windows and side windows with sheet-like blinds. The various embodiments described above can also be applied to a shielding device attached to a building or the like other than an automobile.

The tip member may be a pair of members composed only of the end holder, in addition to being a long member along the width direction D3. Further, even if the tip member is not supported by the support portion, the bending portion of the arm mechanism is connected to the intermediate member that moves along the pair of support portions, so that the deformation of the arm mechanism due to the application of a load is reduced. In addition, an effect is obtained in which the shielding sheet can be smoothly accommodated by the positioning mechanism.
The arm mechanism may be asymmetrical.
In addition to centering the intermediate member, the positioning mechanism may position the intermediate member at a predetermined position in the width direction D3 that is deviated from the intermediate position according to the usage scene.

  A third urging member such as a tension coil spring may be interposed between the bent portions FP1 and FP2 of the arm mechanism and the end holders 64a and 64b. Accordingly, when the arm mechanisms AR1, AR1 are bent, the tension coil spring biases the bent portions FP1, FP2 outward in the width direction. Therefore, the force with which the accommodation device pulls out the shielding sheet against the force of accommodating the shielding sheet is small. Further, since the tension coil spring assists in positioning the intermediate member 64 at a predetermined position in the width direction D3, the displacement of the intermediate member 64 in the width direction D3 when the bent portions FP1 and FP2 are not in contact with the positioning mechanism. Can be reduced.

Even if the driving means 80 is not provided, the tonneau cover 30 can be pulled out and housed by holding the tip member 63 and the tip portion of the tonneau cover 30 by hand. An effect of accommodating the shielding sheet is obtained.
Further, the shielding device can be constituted only by the shielding sheet, the accommodation device, the pair of support portions, the tip member, the intermediate member, the pair of arm mechanisms, and the positioning mechanism, and the shielding sheet can be smoothly accommodated even in this shielding device. The effect which becomes possible is acquired.
In other words, the above-described basic actions and effects can be obtained even with an apparatus and method that do not have the constituent elements according to the dependent claims but only the constituent elements according to the independent claims.
Furthermore, the present invention is not limited to the above-described embodiments and modifications, and the configurations disclosed in the above-described embodiments and modifications are mutually replaced, the combinations are changed, the known technology, and the above-described configurations.
