Description

  The present invention relates to a multi-plate sunshade device in which a plurality of sunshade panels are superposed on each other in a fully open position and are developed on the same surface by abutting edges of each other in a fully closed position.

  In order to enhance the feeling of opening of the passenger compartment, a vehicle body in which a part of the roof is constituted by a glass panel is known. In such a vehicle with a glass sunroof, it is common to provide a sunshade panel that is slidable in the front-rear direction under the glass panel in order to limit the insertion of sunlight into the vehicle interior.

  As a sunshade device having such a slidable sunshade panel, the left and right side edges of the three panels are slid onto the three-stage guide rails corresponding to each panel, and the ends of the adjacent panels are front and rear. An arrangement is known in which an engagement / disengagement mechanism is provided at the edge, and the front panel is moved forward and backward to open and close the three panels in the manner of a sliding door (see Patent Document 1). ).

  This conventional structure has a problem that when it is fully closed, there is an upper and lower step between the front and rear panels, which impairs the appearance. In addition, a guide rail on which the three panels slide individually is necessary, and the thickness of the guide rail for three steps is required over the entire length of the movement range of the frontmost panel. It was difficult to achieve both an increase in head clearance.

In order to deal with such inconveniences, a plurality of panels are deployed on the same surface by abutting the edges of each other in the fully closed position, and in the retracted position, the rear panel is pushed up by a spring means, and the front panel is below the front panel. Japanese Patent Application Laid-Open No. H10-228707 proposes a configuration in which a housing gap is opened.
JP 2004-249851 A Japanese Patent Laid-Open No. 5-24437

  However, according to the configuration described in Document 2, since a mechanism for pushing up the rear panel at the storage position is required, the structure is complicated, and the number of parts and the number of assembly steps are increased, resulting in an increase in manufacturing cost.

  The present invention has been devised to eliminate such disadvantages of the prior art, and its main purpose is to prevent the increase in manufacturing cost between the front and rear sunshade panels in the fully closed state. It is an object of the present invention to provide a multi-plate sunshade device that is configured so that both a reduction in the height dimension of the vehicle body and an increase in the head clearance can be achieved.

  In order to solve such problems, the present invention provides a plurality of sunshade panels composed of a drive panel and a driven panel, a guide rail for guiding the forward and backward movement of the drive panel and the driven panel, and each panel to be slid on the guide rail. In the multi-plate sunshade device having the front slide shoe and the rear slide shoe provided, the rear slide of the upper guide rail 11U and the driven panel and the drive panel 2 with which the front slide shoe 9F (10F) of the driven panel 3 (4) slides. The lower guide rail 11L to which the shoe 9R (10R, 8R) slides, and the panel member provided at the rear end portion of the front panel and the front end portion of the rear panel so as to connect the panels adjacent to each other at the time of movement. Guide the removal mechanism (pins 13 and 14, cam grooves 15 and 16) and the front slide shoe of the driven panel The front slide shoe storage portion 17 that is coupled to the upper guide rail to be stored in the upward direction (preferably perpendicular to the upper guide rail) and the rear slide shoe of the driven panel are guided to the lower guide rail to be stored. And a rear slide shoe storage portion 18 that is coupled upward (preferably obliquely upward with respect to the lower guide rail), and the front slide shoe in the driven panel is on the upper guide rail and the rear slide shoe is on the lower guide rail. The plurality of panels are superposed on each other in the open position by moving them forward and backward, and their edges are butted against each other in the closed position.

  According to the present invention, three or more sunshade panels can be slid by the two-stage guide rails and can be overlapped with each other in the fully open position, and in the fully closed position, the ends of the sunshade panels adjacent to each other. Edges can be abutted on the same plane. Therefore, since no special biasing means is required to superimpose a plurality of sunshade panels in multiple stages, there is no increase in manufacturing cost, and there is an upper and lower step between the front and rear sunshade panels in the fully closed state. Moreover, since the height dimension of the guide rail does not become excessive, it is possible to achieve both a reduction in the height dimension of the vehicle body and an increase in the head clearance.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

  1 and 2 are schematic side views of a multi-plate sunshade device configured according to the present invention as seen from the vehicle body center side. This sunshade device 1 is described in Document 1 in that an opening (not shown) provided in an inner roof of a vehicle is opened and closed by three sunshade panels including a front panel 2, a middle panel 3, and a rear panel 4. Since it is the same as the known one, a detailed description of the installation position is omitted.

  The three sunshade panels 2, 3, 4 according to the present invention are supported at their left and right ends by corresponding stays 5, 6, 7, respectively. The pair of left and right stays 5, 6, 7 have a generally rectangular bar shape that is long in the front-rear direction, and a pair of slide shoes 8, 9, 10 that protrude outwardly at the front and rear ends of each side will be described later. By sliding on the guide rail, it can slide back and forth. Note that FIG. 1 omits stays, and FIG. 2 omits panels.

  As shown in FIG. 3, the guide rail G for sliding the slide shoes 8, 9, 10 is formed in a two-stage upper and lower stages of an upper guide rail 11U and a lower guide rail 11L having a U-shaped cross-section. A cable guide groove 12 having a substantially C-shaped cross-section for inserting a push / pull cable (not shown) that is pushed and pulled by an electric motor is integrally formed. The guide rail G can be formed by, for example, extrusion molding using an aluminum alloy.

  The front and rear slide shoes 8F and 8R provided at both front and rear ends of the front panel stay 5 are slid on the lower guide rail 11L. Further, a push / pull cable (not shown) is connected to the front panel stay 5 so that the forward / backward driving force is transmitted. That is, the front panel 2 supported by the front panel stay 5 is configured as a drive panel.

  The front slide shoes 9F and 10F provided at the front end portions of the middle panel stay 6 and the rear panel stay 7 are respectively slidable on the upper guide rail 11U. The rear slide shoes 9R and 10R provided at the rear end portions of the middle panel stay 6 and the rear panel stay 7 are respectively slidable on the lower guide rail 11L. Further, the rear ends of the front panel stay 5 and the middle panel stay 6, that is, rearward of the rear slide shoes 8R and 9R, the front ends thereof are directed outward of the opening, in other words, toward the guide rail G. The pins 13 and 14 are integrally projected.

  Pins 13 at the rear end portions of the front panel stay 5 and the middle panel stay 6 corresponding to the front slide stays 5F and 10F on the rear side of the front slide shoes 9F and 10F of the middle panel stay 6 and the rear panel stay 7, respectively. -Cam grooves 15 and 16 are formed so as to be inclined forward and to be engaged with 14, and whose lower ends are opened rearward. These pins 13 and 14 and cam grooves 15 and 16 constitute a panel engagement / disengagement mechanism for connecting adjacent panels forward and backward during movement. The front panel is supported by the front panel stay 5 that is driven by the push / pull cable, with the middle panel 3 supported by the middle panel stay 6 and the rear panel 4 supported by the rear panel stay 7. It is comprised as a driven panel connected to 2 and following.

  The upper guide rail 11U is shorter than the lower guide rail 11L by an amount corresponding to the distance between the front slide shoes 9F and 10F and the rear slide shoes 9R and 10R of the stay 6 for the middle panel and the stay 7 for the rear panel. At the rear end, a front slide shoe storage portion 17 that can be engaged with and detached from the front slide shoes 9F and 10F of the middle panel stay 6 and the rear panel stay 7 is coupled. The front slide shoe storage portion 17 is formed in a direction perpendicular to the upper guide rail 11U. A rear slide shoe storage portion 18 that can be engaged with and detached from the rear slide shoes 9R and 10R of the middle panel stay 6 and the rear panel stay 7 is coupled to the rear end portion of the lower guide rail 11L. Thereafter, the slide shoe storage portion 18 is formed obliquely upward with respect to the lower guide rail 11L.

  Next, the operation procedure of the device of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, the three panels 2, 3, 4 overlap each other in the retracted position of the panels 2, 3, 4 where the sunshade device 1 is fully opened. In this state, the front slide shoe 8F and the rear slide shoe 8R of the front panel stay 5 are both in sliding contact with the lower guide rail 11L. Further, both front slide shoes 9F and 10F of the middle panel stay 6 and the rear panel stay 7 are both engaged with a front slide shoe storage portion 17 integrally coupled to the rear end of the upper guide rail 11L, and both rear slide shoes are engaged. Both 9R and 10R are engaged with the rear slide shoe storage portion 18 integrally coupled to the rear end of the lower guide rail 11L.

  When the sunshade device 1 is closed from the fully open position shown in FIGS. 1 and 2, when the push / pull cable coupled to the front end of the front panel stay 5 is pushed forward, the front and rear slide shoes 8F and 8R are guided to the lower guide. The front panel stay 5 slidably engaged with the rail 11L moves forward, and the front panel 2 supported by the front panel stay 5 moves forward.

  When the front panel stay 5 continues to advance and the pin 13 projecting outward at the rear end thereof engages with the cam groove 15 provided at the front end of the middle panel stay 6 (see FIG. 4), The pin 13 of the panel stay 5 moves in the horizontal direction along the lower guide rail 11L. However, the cam groove 15 of the middle panel stay 6 is inclined forward, and in this state, the cam groove 15 Since the front slide shoe 9F integrated with the front slide shoe storage portion 17 is restricted from moving in the front-rear direction by the vertical front wall of the front slide shoe storage portion 17, the front panel stay 5 has the pin 13 of the front panel stay 5 moved forward. The front end is pulled down. Accordingly, the front slide shoe 9 </ b> F of the middle panel stay 6 moves downward in the front slide shoe storage portion 17.

  Since the lower end of the front slide shoe storage portion 17 is connected to the upper guide rail 11U, the front slide shoe 9F of the middle panel stay 6 advances along the upper guide rail 11U as it is. As the middle panel stay 6 moves forward, the rear slide shoe 9R of the middle panel stay 6 slides down the front inclined surface of the rear slide shoe storage portion 18 and enters the lower guide rail 11L as it is. The stay 6 and the middle panel 3 supported by the stay 6 continue to move forward together with the front panel stay 5 and the front panel 2.

  At this time, as shown in FIG. 5, the convex portion 20 formed on the lower surface of the front edge portion of the middle panel 3 is engaged with the concave portion 19 formed on the upper surface of the rear edge portion of the front panel 2.・ The bottom surface of 3 is a continuous and substantially identical surface.

  When the front panel stay 5 and the front panel 2 continue to advance, the pin 14 provided at the rear end of the middle panel stay 6 enters the cam groove 16 provided at the front end of the rear panel stay 7, In the same manner as described above, the middle panel stay 6 and the middle panel 3, and the rear panel stay 7 and the rear panel 4 move forward together.

  As a result, when the three panels 2, 3, and 4 move forward in a row and reach the fully closed position, the driving force of the push / pull cable is cut off by the action of a separate limit switch, etc., and the three panels 2・ Stops at the fully closed position with 3 and 4 connected. In this state, the lower surfaces of the three panels 2, 3, 4 extend on the same continuous surface.

  When opening the sunshade device 1, if the push / pull cable is pulled backward, the pin 13 at the rear end of the front panel stay 5 pushes the cam groove 15 at the front end of the middle panel stay 6, and the The pin 14 at the rear end of the panel stay 6 pushes the cam groove 16 at the front end of the rear panel stay 7. As a result, the three panels 2, 3, 4 are retracted in a line.

  The rear slide shoe 10R of the rear panel stay 7 is continuous with the rear end portion of the lower guide groove 11L and ascends the inclined surface of the rear slide shoe storage portion 18 to reach the rearmost end of the inclined surface. When the front slide shoe 10F is restricted from being retracted by the rear wall of the front slide shoe storage portion 17 at the rear end of the upper guide rail 11U, the pin 14 of the middle panel stay 6 is inserted into the cam groove 16 of the rear panel stay 7. By moving, the front slide shoe 10 </ b> F of the rear panel stay 7 is pushed up in the front slide shoe storage portion 17. As a result, the rear panel stay 7 and the rear panel 4 rise. Then, the pin 14 at the rear end of the middle panel stay 6 is disengaged from the cam groove 16 at the front end of the rear panel stay 7, and the rear slide shoe 9R of the middle panel stay 6 retreats from the lower guide rail 11L. In this way, the middle panel 3 overlaps the lower surface of the rear panel 4 (returns to the state of FIG. 4 through the state of FIG. 6).

  When the front panel 2 is further retracted, the middle panel 3 is pushed up as the pin 13 at the rear end of the front panel stay 5 moves in the cam groove 15 at the front end of the middle panel stay 6. In the same manner as described above, the rear slide shoe 9R at the rear end of the middle panel stay 6 is stored in the rear slide shoe storage portion 18, and the front slide shoe 9F at the front end of the middle panel stay 6 is stored at the front slide shoe storage portion 17. The middle panel 3 is raised and the front panel 2 is retracted to a position where it overlaps the lower surface of the middle panel 3 (returns to the state of FIG. 2).

  According to the present invention configured as described above, when the door is fully opened, the longitudinal wall of the front slide shoe storage portion 17 restricts the longitudinal movement of the front slide shoes 9F and 10F of the middle panel 2 and the rear panel 4. In addition, the back-and-forth movement does not occur, and the engagement of the pins 13 and 14 with the cam grooves 15 and 16 releases / reconnects the front and rear panels 2, 3, and 4. A smooth and quiet opening / closing operation is realized without generating a hitting sound during engagement / disengagement. In particular, by providing an urging means for applying a downward pressing force to the rear panel 4 and the middle panel 3 in the storage position, it is possible to reliably prevent the back-and-forth in the vertical direction between the panels overlapping in the storage position. be able to.

Note that the engagement / disengagement mechanism between the panels adjacent to each other in the front-rear direction is not limited to the pin and the cam groove in this embodiment. In the above embodiment, the front slide shoe storage portion 17 is coupled to the rear end of the upper guide rail 11U. However, the retreat limit of the middle panel stay 6 and the rear panel stay 7 is limited to the rear slide shoe storage portion. 18, the front slide shoe storage portion 17 does not necessarily have to be coupled to the rear end of the upper guide rail 11 </ b> U. Even if the upper guide rail 11 </ b> U extends to the rear of the front slide shoe storage portion 17. good.
