And a sunshade device comprising a connecting mechanism comprising a cam groove having a lower end opened When the adjacent disengagement occurs and the cam pin deviates from the normal movement locus, when the sunshade panel is operated in the opening direction, the rear end of the support bracket on the front sunshade panel is rearward. The front sunshade panel of the sunshade panel is pressed by pushing the periphery of the front end of the support bracket toward the rear and the slider of the rear sunshade panel is released from the restriction of the vertical displacement by the guide rail at a predetermined position. The rear end of the support bracket is pushed up around the front end of the support bracket in the rear sunshade panel to return the cam pin to a normal movement locus.

  According to the first aspect of the present invention, when the adjacent sunshade panel is moved, the above-described upward forced external force is temporarily applied, and the engagement between the adjacent front sunshade panel and the rear sunshade panel is released. Even in this case, as described above, the area around the rear end of the support bracket in the front sunshade panel pushes up the area around the front end of the support bracket in the rear sunshade panel, and then moves in the opening direction. The cam pin can be restored to the normal movement locus again, and then returned to the engaged state by movement in the closing direction thereafter, so that the adjacent sunshade panel is not damaged or damaged due to interference between parts other than the support bracket. Large-scale repair of removing the sunshade device from the vehicle body is necessary. No.

  According to the invention of claim 2, when the periphery of the rear end of the support bracket of the front sunshade panel contacts the front end of the support bracket of the rear sunshade panel for pressing, the front sunshade panel and the rear By preventing the sunshade panel from coming into contact, as described above, there is an action in which the periphery of the rear end of the support bracket in the front sunshade panel pushes up the front end of the support bracket in the rear sunshade panel. A reliable return to the engaged state can be realized by the opening / closing operation.

  Even when the adjacent sunshade panels are once disengaged during the movement of the sunshade panel, the present invention next moves the sunshade panel next to the adjacent front sunshade panel and the rear The sunshade panel can return to the engagement without interference, and the troublesome repair work that is time-consuming and expensive is not necessary. In addition, since the vehicle is restored by a simple operation of performing the above-described series of opening and closing operations after the operation in the closing direction, the traveling of the vehicle to which the sunshade device is attached in a state where the adjacent sunshade panels are not engaged with each other. It is possible to avoid the unstable situation of continuing.

Hereinafter, preferred embodiments in which the present invention is applied to a sunshade apparatus will be described.
For the sake of explanation, the term “upper and lower” is based on the state in which the sunshade device is attached to the vehicle.
1 and 2 are a top view and a partially exploded perspective view of the sunshade device 1, respectively. The sunshade device 1 according to the present embodiment is a type in which a rear sunshade panel is positioned above and a front sunshade panel is stored under the sunshade panel, and three sunshade panels are configured.

In FIG. 1, a rectangular glass panel 3 indicated by a virtual line is attached to a roof outer plate 2 of a vehicle, and a sunshade device 1 that performs daylighting and light shielding from the glass panel 3 inside a ceiling of a passenger compartment. Is decorated.
The sunshade device 1 is attached to the inner opening 4 of the roof so as to be openable and closable in the vehicle front-rear direction. In the closed state, the sunshade device 1 is arranged side by side in the vehicle front-rear direction, and a plurality of sunshade panels 5A to 5C The front sliders 6A to 6C and the rear sliders 7A to 7C, the guide rails 8 for guiding the front and rear movements of the front sliders 6A to 6C and the rear sliders 7A to 7C, and the sunshade panel 5A located at the forefront. A connecting mechanism 10 for detachably connecting adjacent sunshade panels (referring to the relationship between 5A and 5B, and between 5B and 5C) so that the driving source 9 to be connected and the sunshade panels 5A to 5C are interlockedly opened and closed. And.

  As shown in FIG. 2, support brackets 11A to 11C extending in the vehicle front-rear direction are attached to the left and right edges of the sunshade panels 5A to 5C, and the vehicle width direction outer surfaces of the support brackets 11A to 11C On the side, the front sliders 6A to 6C and the rear sliders 7A to 7C are formed to project. The sunshade panels 5A to 5C slide open and close in the vehicle front-rear direction when the front sliders 6A to 6C and the rear sliders 7A to 7C are guided by the left and right guide rails 8 and linearly move.

The guide frame 12 constituting the guide rail 8 will be described. The guide frame 12 is a member having a constant cross-sectional shape extending in the vehicle front-rear direction, and is made of, for example, an extruded shape made of an aluminum alloy.
The guide frame 12 constitutes a guide rail 8 that opens toward the inner side in the vehicle width direction. In this embodiment, the guide rail 8 is composed of two upper and lower stages of an upper rail 8A and a lower rail 8B. Yes.
Both the upper rail 8A and the lower rail 8B exhibit a rectangular cross-sectional space opened toward the inner side in the vehicle width direction. Each of the rear sliders 7A to 7C is guided by the lower rail 8B, and the front sliders 6B and 6C are guided by the upper rail 8A. The front slider 6A is guided by the lower rail 8B.

  In the guide frame 12, a cable groove 8C for inserting the push-pull cable 16 (FIG. 1) is formed below the lower rail 8B. The push-pull cable 16 is push-pull operated by the drive source 9 (electric motor or the like) shown in FIG. 1, and its tip is connected to the support bracket 11A of the sunshade panel 5A. The driving force applied to the sunshade panel 5A is transmitted to the remaining sunshade panels 5B and 5C via the coupling mechanism 10.

  As shown in FIG. 2, the coupling mechanism 10 is a cam mechanism in which the cam pins 18 are detachably fitted into the cam grooves 19, and the sunshade panels (5A and 5B, 5B and 5C) can be freely engaged and disengaged. As a mechanism. In the cam mechanism for connecting the sunshade panel 5B and the sunshade panel 5C, the cam pin 18 is formed on the front sunshade panel 5B side, and the cam groove 19 is formed on the rear sunshade panel side, that is, the sunshade panel 5C side. This structure is the same in the relationship between the sunshade panel 5A and the sunshade panel 5B.

An inclined rail 20 is attached to the rear end of the lower rail 8B so as to extend obliquely rearward and upward.
At the time of storage, the rear rails 7C and 7B of the sunshade panel 5C and the sunshade panel 5B are inserted into the inclined rail 20 in order. When the rear sliders 7C and 7B rise on the inclined rails 20, respectively, the front sliders 6C and 6B can rise through the front slider raising opening 30 formed at the rear of the rear end of the upper rail 8A. Thus, the sunshade panels 5C and 5B can move upward.
The connection state by the connection mechanism 10 is configured to be released when the rear sliders 7 </ b> C and 7 </ b> B are raised to a predetermined position on the inclined rail 20.

  Here, a schematic operation of the sunshade apparatus will be described. FIG. 6 is an explanatory diagram of the operation of the sunshade device. Since the roof of the vehicle is slightly curved upward in the vehicle width direction, the sunshade panels 5A to 5C are also slightly curved upward in accordance with this, and are shown by phantom lines in FIG. Further, the positions of the sunshade panels 5A to 5C are the height positions as viewed in cross section at the center in the vehicle width direction.

  FIG. 6A shows a state in which the sunshade panels 5 </ b> A to 5 </ b> C are closed to the front, and each cam pin 18 is located near the upper end of the cam groove 19. The front end of the sunshade panel 5B overlaps the upper part of the rear end of the sunshade panel 5A so that excessive force is not applied, and the front end of the sunshade panel 5C also does not apply excessive force to the upper part of the rear end of the sunshade panel 5B. overlapping. The bottom surfaces of the sunshade panels 5A to 5C are flush with each other.

  When the drive source 9 (FIG. 1) is driven from the state of FIG. 6A, the sunshade panel 5A slides backward via the front slider 6A and the rear slider 7A by the pull operation of the push-pull cable 16 (FIG. 1). To do. At this time, the cam pin 18 on the sunshade panel 5A side presses the cam groove 19 on the sunshade panel 5B side. On the sunshade panel 5A side, the front slider 6A and the rear slider 7A fit into the lower rail 8B, and on the sunshade panel 5B side, the front slider 6B fits into the upper rail 8A and the rear slider 7B fits into the lower rail 8B. The cam pin 18 and the cam groove 19 are not displaced in the vertical direction, and the pressing force from the cam pin 18 acts as a force for sliding the sunshade panel 5B backward. Similarly, the sunshade panel 5C is also slid rearward, whereby the sunshade panels 5A to 5C are integrally slid rearward.

  FIG. 6B shows a state in which the rear slider 7C of the sunshade panel 5C has reached the rear end of the lower rail 8B. From this state, the rear slider 7C moves to the inclined rail 20 as shown in FIG. 6C. Ascend along. The state of the rising process at this time will be described in detail with reference to FIGS. FIG. 7 is an enlarged view around the rear end of the upper rail 8 </ b> A, and FIG. 8 is an enlarged view around the inclined rail 20. The position of the reference symbol P1 relating to the front slider 6C in FIG. 7 and the position of the reference symbol P1 relating to the rear slider 7C in FIG. 8 both indicate the position of the front slider 6C and the position of the rear slider 7C in FIG. 7 and 8 both indicate the position of the front slider 6C and the position of the rear slider 7C in FIG. 6C. In the process of moving from the position of P1 to the position of P2, as shown in FIG. 7, the front slider 6C is restrained in the vertical direction by the upper rail 8A. Therefore, the rear slider 7C shown in FIG. The front slider 6C that slides under the movement restraint in the vertical direction is lifted while slightly rotating counterclockwise around the instantaneous center.

  Further, since the front slider 6C itself slides while rotating counterclockwise, the shape of the front slider 6C can be rotated in the upper rail 8A as shown in FIG. With the central portion in the vehicle front-rear direction as the maximum height, the upper surface portion is inclined downward and the lower surface portion is inclined upward from the central portion toward the front and rear directions. If the front slider 6C has a structure that can rotate relative to the support bracket 11C (FIG. 6) and is provided with a biasing means such as a spring material for position restoration, the front slider 6C The side view shape may be a rectangle. In the process from FIG. 6B to FIG. 6C described above, the cam groove 19 moves upward with respect to the cam pin 18.

  The position P2 of the rear slider 7C in FIG. 8 is a position where the front slider 6C in FIG. 7 is in contact with the stopper wall 23, and is a position where the rear slider 7C cannot be further raised. At this time, as shown in FIG. 7, a front slider raising release portion 30 is formed on the upper portion of the front slider 6C at the position P2. Accordingly, the cam groove 19 is moved upward in response to the pressing force from the cam pin 18, and the front slider 6C, which has been released from the upward movement restraint, rotates clockwise around the rear slider 7C as a rotation center. Ascending through the opening 30 for raising the front slider (state shown in FIG. 6D). The stopper function by the stopper wall 23 can also be provided on the inclined rail 20 side.

  And as shown in FIG.6 (e), when the cam pin 18 remove | deviates from the cam groove 19 which is moving upwards, the connection of the sunshade panel 5B and the sunshade panel 5C is released. When the cam pin 18 is disengaged from the cam groove 19, the cam pin 18 is disengaged while pressing the bottom surface portion of the support bracket 11 </ b> C upward. Therefore, rattling between the sunshade panel 5 </ b> B and the sunshade panel 5 </ b> C accompanying separation is also possible. Does not occur.

  Eventually, as shown in FIG. 6 (f), when the rear slider 7B of the sunshade panel 5B reaches the rear end of the lower rail 8B, the camshaft 18 on the sunshade panel 5A side has a function similar to that of the sunshade panel 5C. The rear slider 7B is raised along the inclined rail 20 by the pressing force. Then, when the front slider 6B comes into contact with the stopper wall 23 shown in FIG. 7, the rise of the rear slider 7B is restricted.

  At this time, since the front slider raising release portion 30 is formed at the upper portion of the front slider 6B, the cam groove 19 on the sunshade panel 5B side receives the pressing force from the cam pin 18 on the sunshade panel 5A side. The front slider 6B rotates clockwise around the rear slider 7B as the center of rotation, and ascends through the front slider ascending opening 30 (state shown in FIG. 6 (h)).

  Then, as shown in FIG. 6 (i), when the cam pin 18 is removed from the cam groove 19 moving upward, the connection between the sunshade panel 5A and the sunshade panel 5B is released. In this state, the upper surface of the support bracket 11A presses the support bracket 11B upward, and the upper surface of the support bracket 11B presses the support bracket 11C upward. Thereby, the sunshade panels 5B and 5C are positioned and accommodated in a substantially horizontal shape. At this time, the front end portions of the front sliders 6 </ b> C and 6 </ b> B are in contact with the position shift prevention wall portion 22. In FIG. 7, the position of the front slider 6C at that time is indicated by reference numeral P3. Further, the position of the rear slider 7C at that time is indicated by a symbol P3 in FIG. That is, regarding the sunshade panel 5C, the rear end surface of the rear slider 7C is in contact with the lower inclined surface 20a of the inclined rail 20, and the front end of the front slider 6C is in contact with the misalignment prevention wall portion 22, thereby the sunshade panel 5C. The positional deviation in the vehicle front-rear direction is prevented. The sunshade panel 5B is also prevented from being displaced in the vehicle longitudinal direction for the same reason.

  Then, as shown in FIG. 6 (j), the support bracket 11A slides to a predetermined rear position, whereby the operation in the opening direction of the sunshade panels 5A to 5C is completed. The sunshade panel 5B is accommodated with a gap under the sunshade panel 5C, and the sunshade panel 5A is accommodated with a gap under the sunshade panel 5B. Since the support bracket 11A is stopped while being pulled by the push-pull cable 16, the sunshade panel 5A is not displaced in the vehicle front-rear direction.

  Next, the operation in the closing direction of the sunshade panels 5A to 5C will be briefly described. When the support bracket 11A slides forward from the state of FIG. 6 (j), the cam pin 18 on the sunshade panel 5A side is sunshaded. It abuts around the lower end of the cam groove 19 on the panel 5B side, and is engaged and guided to the cam groove 19. When the support bracket 11A slides forward, the cam pin 18 pulls up the cam groove 19 and the front slider 6B of the support bracket 11B is lowered. Subsequent operations basically move in the opposite direction to that during operation in the opening direction, and the description thereof is omitted.

A configuration of a sunshade device to which the present invention is applied will be described.
FIG. 3 is an enlarged cross-sectional view of the configuration in the vicinity of the coupling mechanism 10 in a state where the sunshade device is sliding.
Adjacent sunshade panels 5B and 5C are positioned so that the rear sunshade panel front end 5C1 overlaps the front sunshade panel rear end 5B1. Specifically, the flange portion 5B11 of the front sunshade panel rear end 5B1 is positioned in the groove portion 5C11 of the rear sunshade panel front end 5C1. At this time, the cam pin 18 of the support bracket 11B of the front sunshade panel 5B is formed on the support bracket 11C of the rear sunshade panel 5C, and engages with the cam groove 19 having an open end, and engages the adjacent sunshade panel. is doing.

  Next, the operation of the present invention will be described with reference to FIGS. 1 to 5 as appropriate. Here, in order to facilitate understanding of the present invention, a comparative example other than the application of the present invention will be described with reference to FIG.

  FIG. 4 (a) shows that when the sunshade panel is moved in the closing direction, the rear sunshade panel front end 5C1 (see FIG. 3) is lifted by a forced upward external force, and the front sunshade panel rear end 5B1 (FIG. 3) is lifted. It is explanatory drawing which shows the condition from which engagement with reference was disengaged. FIG. 4B shows the front slider 6C of the rear sunshade panel 5C and the front of the rear sunshade panel 5C in a situation where the rear sunshade panel front end 5C1 and the rear sunshade panel rear end 5B1 interfere with each other when the sunshade panel moves in the opening direction. It is an expanded sectional view including the state of the cam pin 18 of the sunshade panel 5B. Fig.5 (a) is an expanded sectional view of the sunshade apparatus to which this invention is applied. FIG. 5B is an explanatory diagram illustrating a situation where the engagement is restored.

As shown in FIG. 3, when the sunshade panel is moved in the closing direction, the sunshade panels 5B and 5C are engaged and slid along the guide rail, but the front slider of the support bracket 11C. When 6C is directly below the front slider lifting opening 30 (see FIG. 4A), the upper restraint by the guide rail 8 is eliminated. At this time, when an upward external force is applied to the rear sunshade panel 5C, the engagement is disengaged, and the front sunshade panel 5B continues to move leftward in FIG. 5B and 5C are in a separated state.
As the upward external force, it is assumed that the arm or head of a boarded person hits and accidentally pushes the sunshade panel 5C upward.

  As shown in FIG. 4 (b), the separated sunshade panels 5B and 5C have a rear sunshade panel front end 5C1 (see FIG. 3) and a front sunshade panel rear end 5B1 (see FIG. 3) when the sunshade panel is operated in the opening direction. May interfere with each other and may not be able to return to the original engaged state, or an excessive force may be applied to the sunshade panels 5B and 5C.

  On the other hand, the sunshade device to which the present invention is applied has a rear sunshade panel front end 5C1 (see FIG. 3) and a front sunshade panel rear end when the sunshade panel is operated in the opening direction, as shown in FIG. Before contact with 5B1 (see FIG. 3), the periphery of the front end of the support bracket 11C of the rear sunshade panel 5C and the periphery of the rear end of the support bracket 11B of the front sunshade panel 5B (cam pin 18) come into contact.

  The front sunshade panel 5B is constrained downward in FIG. 5B because the rear slider 7B slides in the guide rail 8B. At this time, in the rear sunshade panel 5C, the front slider 6C is positioned immediately below the front slider lifting opening 30 formed at the rear of the rear end of the upper rail 8A. ing. At this time, the rear slider 7C has reached the upper end of the inclined rail 20, and the front slider 6C is in a state in which it cannot move further rearward.

Accordingly, when the front sunshade panel 5B moves rightward in FIG. 5B, the front end of the rear sunshade panel 5C is pushed upward by the curved surface of the cam pin 18 in FIG. The front end height position of the sunshade panel 5C is higher than the rear end height position of the front sunshade panel 5B. This prevents mutual interference.
After passing through the tip, the cam pin 18 then slides on the lower surface 11C12 of the support bracket 11C in FIG. 5B, and then the cam pin 18 comes into contact with the downwardly inclined surface 11C13, and the inclined downwardly to the right. By sliding along the surface 11C13, the periphery of the front end of the support bracket of the rear sunshade panel is further pushed up.

  The cam pin 18 returns to the normal movement trajectory position over the inclined surface 11C13 that is lowered to the right. That is, it returns to the position of FIG. Thereafter, when operating in the closing direction, the rear sunshade panel front end 5C1 overlaps the front sunshade panel rear end 5B1, and the sunshade panel 5B descends so that the flange portion 5B11 of the front sunshade panel rear end 5B1 becomes the rear sunshade panel front end. The sunshade panels 5B and 5C are returned to the engaged state as shown in FIG. 3 by being accommodated in the groove 5C11 of 5C1.

  As described above, according to the present invention, even when the adjacent sunshade panels are once disengaged when the sunshade panels are moved, the next time the sunshade panels are moved in the opening direction, Thus, the front sunshade panel and the rear sunshade panel can return to the normal movement locus position without interference, and then the engagement can be returned by moving in the closing direction.
