Hereinafter, each embodiment of the fixing member 1 for a tonneau cover apparatus according to the present invention will be described.
<First Embodiment>

  As shown in FIG. 3, the fixing member 1 is provided at the tonneau cover side front end portion of the lower surface 12 a of the board 12. 3 shows only the fixing member 1 provided on the right side of the fixing members 1 provided on both sides of the board 12 in the width direction. For example, as shown in FIGS. 3 and 4, the fixing member 1 includes a lock piece 2 that engages with the vehicle body side engaging portion 15, and first and second cases 3 and 4 as cases that hold the lock piece 2. A compression spring 5 (hereinafter referred to as a spring) as an urging member that urges the second case 4 together with the lock piece 2 in the separating direction with respect to the first case 3 is configured.

As shown in FIG. 3, the first case 3 includes a first cylindrical portion 30 (cylindrical portion) having a circular opening 30 a on one side in the longitudinal direction, and a board provided on both sides in the front-rear direction of the back surface of the first cylindrical portion 30. And a fixing portion 31 in which two fastening holes 31a for fixing to the fixing hole 31 are formed. As shown in FIGS. 5A, 5 </ b> B, and 6, the first cylindrical portion 30 includes two members, a case main body 32 and a lid portion 33. The case main body 32 constitutes a main part of the first cylindrical part 30, and fixed parts 31 are integrally formed on both sides with a rectangular opening 30 b formed in the center of the back surface of the first cylindrical part 30. The lid portion 33 forms a part of the first cylindrical portion 30, and is attached to the rectangular opening 30b from the back side. The longitudinal direction of the first cylindrical portion 30 is the same as the axial center of the first cylindrical portion 30, and is orthogonal to the winding direction of the tonneau cover 11 when attached to the board 12. In the following description, a direction along the axis of the first cylindrical portion 30 is referred to as an axial direction.
An end surface 32a facing the circular opening 30a of the case body 32 in the axial direction is formed with a columnar spring holding portion 32b and a pair of fixed claw locking holes 32c, and the circular opening of the rectangular opening 30b. On the side of the portion 30a, a bent claw locking hole 32d is formed on both sides thereof.

On the other hand, the lid portion 33 is formed with a pair of fixing claws 33b on the end surface 33a on one axial side, and is provided with bending claws 33d on both side surfaces 33c on the other axial side. Then, in a state where the fixing claw 33 b of the lid portion 33 is hooked in the fixing claw locking hole 32 c of the case main body 32, the bending claw 33 d is attached to the case main body 32 by pressing the lid portion 33 from the back side of the case main body 32. The lid 33 is attached to the rectangular opening 30 b of the case body 32 by being latched by the flexure claw locking hole 32 d. A curved surface 33e is formed on the front side of the lid portion 33. The curved surface 33e forms a part of the inner peripheral surface of the first cylindrical portion 30, and the inner peripheral surface of the first cylindrical portion 30 forms a substantially annular shape. An anti-rotation groove 33f that extends linearly in the axial direction is formed in the center in the width direction of the curved surface 33e. An anti-rotation protrusion 41 of the second case 4 described later is fitted in the anti-rotation groove 33f to prevent relative rotation of the second case 4 with respect to the first case 3.
Further, the circular opening 30a of the first case 3 has a notch 30c through which a rotation prevention protrusion 41 of the second case 4 described later is inserted at a position rotated 45 ° in the circumferential direction from the rotation prevention groove 33f of the lid portion 33. Is formed.

  As shown in FIG. 7, the second case 4 has a second cylindrical portion 40 (cylinder portion) that is smaller in diameter than the first cylindrical portion 30 of the first case 3 and is slidably supported in the first cylindrical portion 30. An anti-rotation protrusion 41 that engages with the anti-rotation groove 33f of the lid portion 33 along the axial direction is formed on the outer peripheral surface of the second cylindrical portion 40. On the inner peripheral surface of the second cylindrical portion 40, a columnar guide protrusion 42 (protrusion) that guides the lock piece 2 described later at a position in the same phase as the rotation prevention protrusion 41 is formed.

  As shown in FIGS. 8A and 8B, the lock piece 2 includes a cylindrical base portion 21 that is slidably supported in the second cylindrical portion 40 of the second case 4, and one axial direction of the base portion 21. A small-diameter spring holding portion 22 formed on the side, and an engaging portion 23 that is formed on the other end in the axial direction and engages with the vehicle body side engaging portion 15. A cam groove 24 having a substantially right triangle shape is provided on the outer peripheral surface of the base portion 21.

  Here, in the present embodiment, the motion conversion mechanism 6 is configured by the guide protrusion 42 formed on the second case 4 and the cam groove 24 formed on the lock piece 2. The cam groove 24 has an inclined portion 24a that is inclined with respect to the axial direction. When the end portion on the spring holding portion 22 side of the inclined portion 24a is the inclined end portion B and the end portion on the engaging portion 23 side is the inclined end portion C, The groove width gradually increases from the inclined end B toward the inclined end C. The board 12 tilts and the second case 4 rotates so that the rear end of the board 12 is pressed downward and the rear end is lowered while the rear end of the board 12 is pressed downward from the fixing member 1 of the board 12 to which the fixing member 1 is fixed. Then, the guide protrusion 42 moves from the inclined end portion B to the inclined end portion C, and accordingly, the lock piece 2 is pulled into the second case 4. Although details will be described later, since the lock piece 2 is prevented from rotating by the vehicle body side engaging portion 15, the lock piece 2 does not rotate, and the lock piece 2 is rotated along with the rotation of the second case 4 in which the guide protrusion 42 is formed. 2 is drawn. In other words, the motion conversion mechanism 6 converts the rotation of the second case 4 relative to the lock piece 2 into the linear motion of the lock piece 2 relative to the second case 4. For example, the lock piece 2 is set to be retracted by 10 mm as long as the second case 4 rotates by 35 °.

  The base 21 of the lock piece 2 is provided with a guide groove 25 for guiding the guide protrusion 42 of the second case 4 to the cam groove 24 on the outer peripheral surface. The guide groove 25 has an axial groove 25a that opens toward the spring holding portion 22 and extends in the axial direction, and a circumferential groove 25b that extends in the circumferential direction and connects the axial groove 25a and the cam groove 24 to the engaging portion 23 side. Have The connection portion between the circumferential groove 25b and the cam groove 24 allows the guide protrusion 42 to enter the cam groove 24 from the circumferential groove 25b and prevents the advancement from the cam groove 24 to the circumferential groove 25b. 26 is provided. Further, a breakage prevention groove 27 extending from the inclined end B of the cam groove 24 on the side opposite to the inclination direction of the inclined portion 24 a and extending in the circumferential direction is extended, and the breakage prevention groove 27 and the inclined end of the cam groove 24 are extended. The connection portion B is provided with an entry suppression protrusion 28 so that the guide protrusion 42 does not enter the breakage prevention groove 27 due to vibration during traveling of the vehicle. Further, the connecting portion between the circumferential groove 25b and the cam groove 24 and the inclined end portion C are offset in the axial direction by the stepped portion 24b, and the guide protrusion 42 also advances from the cam groove 24 to the circumferential groove 25b. The lock piece 2 is prevented from coming off from the second case 4. An annular recess 21 a is provided closer to the engaging portion 23 than the cam groove 24, and an O-ring 7 that is in sliding contact with the inner peripheral surface of the second case 4 is attached to the annular recess 21 a.

  As shown in FIGS. 3 and 8, the engaging portion 23 has a rectangular shape in connection with the base portion 21 in a cross-sectional view, and a surface facing rearward when the fixing member 1 is assembled is from front to rear. The engaging portion 23 is prevented from being caught on the rail 14 by forming an inclined surface whose width gradually decreases as it goes.

  The vehicle body side engagement portion 15 with which the engagement portion 23 of the lock piece 2 engages has a rectangular recess having a long side in the longitudinal direction of the rail 14, and the engagement portion 23 and the base portion 21 of the lock piece 2. It matches the rectangular shape of the connecting part. The vehicle body side engaging portion 15 has four sides extending substantially perpendicularly from the rail 14 toward the outer side in the vehicle width direction. When the direction of the engaging portion 23 and the long side is matched, the engaging portion 23 is located in the vehicle body side engaging portion 15. And the lock piece 2 is supported so as not to rotate. Moreover, the height dimension of the rail 14 is set to be slightly wider than the outer diameter of the second case 4 that supports the base portion 21 of the lock piece 2 so as to be slidable therein, and the rail 14 is slidable on the second case 4. I support it.

Next, a method for assembling the fixing member 1 will be described.
First, the anti-rotation protrusion 41 of the second case 4 is inserted in phase with a notch 30c formed in the circular opening 30a of the first case 3, and the second case 4 is fitted into the case body 32 of the first case 3. Include. Then, as shown in FIG. 9, the second case 4 is rotated 45 ° to the rear side so that the anti-rotation protrusion 41 is positioned at a substantially central portion in the width direction of the rectangular opening 30 b formed in the case main body 32. Subsequently, the lid 33 is pressed from the back side of the case main body 32 in a state where the fixed claw 33 b of the lid 33 is hooked on the fixed claw locking hole 32 c formed on the end surface 32 a of the case main body 32. As a result, the bending claw 33 d is locked in the bending claw locking hole 32 d formed on the inner peripheral surface of the case main body 32, and the lid portion 33 is attached to the rectangular opening 30 b of the case main body 32. At this time, the rotation prevention protrusion 41 of the second case 4 engages with the rotation prevention groove 33f of the lid portion 33 of the first case 3, and the first case 3 and the second case 4 are assembled so as not to be relatively rotatable. In this state, one of the springs 5 is pressed against the spring holding part 32b formed on the end surface 32a of the case main body 32, and the other of the springs 5 is pressed against the spring holding part 22 of the lock piece 2, thereby The phase is adjusted so that 42 moves in the axial groove 25a of the lock piece 2 and is pressed against the urging force of the spring 5 in the axial direction, and then the guide protrusion 42 moves in the circumferential groove 25b. The lock piece 2 is rotated until it gets over the entry suppression protrusion 28. As a result, the guide protrusion 42 moves in the axial direction in the cam groove 24 by the urging force of the spring 5 and abuts against the inclined end portion B, and the fixing member 1 is assembled (see FIG. 10). Further, the rotation prevention protrusion 41 of the second case 4 faces the wall portion of the first case 3 in which the circular opening 30 a is formed, and the second case 4 is axially outward from the first case 3 by the urging force of the spring 5. Is prevented from coming off.

  The fixing member 1 is fixed to both sides of the front end portion of the board 12 by a fastening member (not shown) penetrating the fastening hole 31a. Therefore, when the rear end portion of the board 12 is pressed downward, the board 12 and the first and second cases 3 and 4 rotate together. When the board 12 is held in parallel with the rail 14, the guide protrusion 42 of the second case 4 is positioned at the inclined end B of the inclined portion 24a of the cam groove 24, and the engaging portion 23 is also shown in FIG. The parallel posture shown is maintained.

Next, the operation of the fixing member 1 assembled in this way will be described in detail with reference to FIGS.
First, when the user grasps the board 12 from the state in which the tonneau cover 11 is accommodated in a tonneau cover case (not shown), that is, the state in which the loading floor is opened, and pulls the board 12 along the rail 14 backward, the board 12 and the board 12 together. The fixing member 1 attached to the vehicle moves rearward of the vehicle. When the fixing member 1 comes to the bent portion 16 of the deck side trim 13 (see FIG. 1), the rail 14 is shortened by 60 mm on both sides, for example, by 30 mm on one side. At this time, the engaging portion 23 of the lock piece 2 is pushed by the rail 14 in a parallel posture, and the second case 4 is brought into the first case 3 against the urging force of the spring 5, for example, the fixing members on both sides. 1 is pulled by 30 mm. When the board 12 is pulled as it is and the fixing member 1 reaches the position of the vehicle body side engaging portion 15, the second case 4 is pushed out against the first case 3 by the urging force of the spring 5, and the lock piece 2 The engaging portion 23 engages with the vehicle body side engaging portion 15. Thereby, the state in which the floor for loading is closed by the tonneau cover 11 is maintained.

  When the rear end of the board 12 is pressed downward by the user from this closed state, the first and second cases 3 and 4 rotate together with the board 12. At this time, as shown in FIGS. 10 and 11, as the second case 4 rotates, the guide projection 42 moves from the inclined end B to the inclined end C of the cam groove 24 along the inclined portion 24a. The piece 2 is drawn into the second case 4. In FIG. 11, the locking piece 2 seems to rotate with respect to the second case 4 because the fixing member 1 is viewed from the back side, but the engaging portion 23 of the locking piece 2 is actually engaged with the vehicle body side. Since it is engaged with the portion 15, the lock piece 2 does not rotate. That is, when the rear end portion of the board 12 is pressed downward from the parallel state shown by the arrow in FIG. 12A, the lock piece 2 does not rotate as shown in FIGS. 12A to 12B. While being maintained in a parallel posture, as shown in FIG. 13 (A) to FIG. 13 (B), it is drawn into the second case 4. Thereby, the engagement between the engagement portion 23 of the lock piece 2 and the vehicle body side engagement portion 15 is released, and the tonneau cover 11 is wound up by the urging force of the winding device.

  When the engagement between the engagement portion 23 of the lock piece 2 and the vehicle body side engagement portion 15 is released, the guide protrusion 42 is pushed back by the urging force of the spring 5 and is inclined from the inclined end C to the inclined end B. The board 12 is moved back along the portion 24a, whereby the board 12 is returned to a substantially parallel state, and the fixing member 1 is moved forward in the rail 14 by the winding device. When the fixing member 1 comes to the bent portion 16 of the deck side trim 13, the second case 4 is pushed out by the urging force of the spring 5 by the vehicle width interval that is longer than the first case 3. Subsequently, the fixing member 1 moves forward along the rail 14 until the tonneau cover 11 is wound around the winding device, and the floor for loading is opened.

  Further, when the user accidentally pulls the rear end of the board 12 upward when the loading floor is closed, the guide protrusion 42 of the second case 4 has the intrusion suppression protrusion 28 inserted into the breakage prevention groove 27 from the inclined end B. Get over and move. Thereby, it can prevent that the guide protrusion 42 interferes with the side wall of the cam groove 24 and is damaged by a user's erroneous operation. The guide protrusion 42 abuts against the entry suppression protrusion 28 in vibration during normal driving of the vehicle. Therefore, the guide protrusion 42 does not move over the entry suppression protrusion 28 and move to the breakage prevention groove 27, and flapping of the board 12 is suppressed.

  Further, at the connecting portion between the circumferential groove 25b and the cam groove 24, the guide protrusion 42 is allowed to enter the cam groove 24 from the circumferential groove 25b, and is advanced to prevent the cam groove 24 from entering the circumferential groove 25b. Since the prevention protrusion 26 is provided and the connecting portion between the circumferential groove 25b and the cam groove 24 and the inclined end C are offset in the axial direction by the step portion 24b, an unintended force acts on the fixing member 1. In addition, the guide protrusion 42 can be prevented from advancing from the cam groove 24 to the circumferential groove 25b via a path opposite to the assembly path and coming off via the axial groove 25.

  As described above, according to the fixing member 1 for the tonneau cover device of the present embodiment, the engaging portion 23 of the fixing member 1 is simply engaged with the vehicle body side engaging portion simply by pressing the rear end portion of the board 12 downward. Since the tonneau cover 11 is taken up from 15 and it is not necessary to hold the board 12 even when the user holds the luggage in both hands, the loading floor can be easily opened.

  Further, since the case is constituted by the first case 3 and the second case 4 that move relative to each other in the axial direction, the first case 3 and the second case 4 can be expanded and contracted in the axial direction, and when the tonneau cover 11 is pulled out, the board 12 Even if the distance between the rails 14 in the vehicle width direction is shortened at the bent portion 16 in the middle from the front to the rear by being pulled rearward, the first and second cases 3 and 4 are contracted and the lock piece 2 follows the rail 14. Thus, the lock piece 2 is prevented from being caught on the rail 14. On the other hand, when the tonneau cover 11 is wound up, the first and second cases 3, 4 are moved even if the board 12 moves forward and the distance in the vehicle width direction of the rail 14 becomes wide at the bent portion 16 on the way from the rear to the front. And the lock piece 2 follows the rail 14, and the lock piece 2 is prevented from being detached from the rail 14.

  In addition, when the first case 3 is formed from a single member, it is necessary to provide a draft to pull the mold from the axial direction. The inner diameter of the cylindrical portion is small on the back side and large on the opening side. 4 may be rattled or caught when sliding, but in the present embodiment, the first case 3 is composed of the case body 32 and the lid portion 33, so there is no need to provide a draft angle and the second case 4. Can be slid smoothly.

  Furthermore, since the fixing member 1 is provided at the front end and both end portions A of the board 12, it is possible to reduce the lifting of the tonneau cover 11 when the rear end portion of the board 12 is pressed downward. Note that the fixing member 1 is not necessarily provided at the front end, and the fixing member 1 may be provided on the rear side depending on the situation such as when the height from the rail 14 to the loading floor is low. However, since the user needs to press the back of the board 12 downward rather than the fixing member 1, it is necessary to ensure the space for it.
