Description

  The present invention relates to a sliding structure of an opening / closing body attached to an opening of a vehicle roof.

  A sunshade panel is mentioned as an example of the opening / closing body attached to the opening part of the roof of a vehicle, The technique regarding the sunshade apparatus of the type which this sunshade panel divided into front and back is described in patent document 1. FIG. This Patent Document 1 describes a technique for storing a sunshade panel in a vertically stacked manner. If described with reference to the reference, the front guide neck 29 formed on the rear slide sunshade 18, It is described that the rear slide sunshade 18 is positioned downward by dropping the rear guide neck shaft 30 into the front partial path 40 and the rear partial path 41 inclined obliquely downward from the guide path 38.

JP-A-8-118959

  In terms of quality, it is important for the sunshade panel to have as little backlash as possible during movement and storage. Accordingly, the sliders (referring to the front guide neck shaft 29, the rear guide neck shaft 30, etc.) do not rattle the guide rails (refer to the guide path 38, the front partial path 40, the rear partial path 41, etc.). It is desirable that the slider is inserted, and in particular, if the slider is brought into surface contact with the guide rail, the stability of the slider increases, so that rattling can be further reduced.

  In this regard, when attention is paid to the shapes of the front guide neck shaft 29 and the rear guide neck shaft 30 described above, both guide neck shafts have a parallelogram when viewed from the side, and this is the main path. It is presumed that this is a treatment that makes surface contact with both the front partial path 40 and the rear partial path 41. However, in the case of such a structure in which the surface contact portion of the slider is changed halfway, the surface contact portion is easily affected by assembly errors or manufacturing errors of each component member, and a stable surface contact function can be obtained. There is a problem that it is difficult. For example, even in the case where the front guide neck shaft 29 and the rear guide neck shaft 30 move without rattling in the guide path 38, there are gaps in the front partial path 40 and the rear partial path 41 due to the aforementioned errors. Problems such as increased size and backlash are likely to occur.

  The present invention was devised to solve such problems, and even if the surface contact portion of the slider with respect to the guide rail is changed halfway, the rattling of the slider can be reduced. An object of the present invention is to provide a slide structure of an opening / closing body.

  In order to solve the above problems, the present invention provides an opening / closing body attached to an opening of a roof of a vehicle, a slider formed on the opening / closing body, a bottom surface portion supporting the sliding surface of the slider, and the bottom surface portion. An open / close body sliding structure that slides the open / close body by moving the slider along the guide rail, wherein the guide rail is substantially A main rail that extends horizontally, and an inclined rail that is formed at an end portion or a middle portion of the main rail and extends in an inclined manner, and a sliding surface of the slider is formed by the main rail. A first sliding surface in surface contact with the bottom surface portion and a second sliding surface in surface contact with the bottom surface portion of the inclined rail are in contact with the upper surface portion of the main rail or the upper surface portion of the inclined rail. Each upper surface And a single spring mechanism that presses the first sliding surface and the second sliding surface against the bottom surface portion of the main rail and the bottom surface portion of the inclined rail, respectively, by a reaction force received from Yes.

  The sliding structure of the opening / closing body includes a spring mechanism that presses the first sliding surface and the second sliding surface of the slider against the bottom surface portion of the main rail and the bottom surface portion of the inclined rail, respectively. The first sliding surface is pressed against the bottom surface of the main rail when positioned, and the second sliding surface is pressed against the bottom surface of the inclined rail when the slider is positioned on the inclined rail. Become. As described above, even if the surface contact portion of the slider with respect to the guide rail changes in the middle, the slider can always be in surface contact with the guide rail stably, thereby reducing the rattling of the slider. be able to.

  Further, since the spring mechanism has both the role of pressing the first sliding surface against the bottom portion of the main rail and the role of pressing the second sliding surface against the bottom surface of the inclined rail, the slider Can be made a simple structure.

  In the present invention, the spring mechanism is attached to the slider and is interposed between the pressing member that contacts the upper surface portion of the main rail or the upper surface portion of the inclined rail, and the pressing member and the slider. The sliding structure of the opening / closing body is characterized by comprising a metal leaf spring.

  In the sliding structure of the opening / closing body, the durability of the spring mechanism can be improved by making the spring of the spring mechanism made of metal. Furthermore, the manufacturing cost can be reduced by using a leaf spring that is easy to process.

  According to the present invention, when the slider formed on the opening / closing body is positioned on the main rail extending substantially horizontally and the inclined rail extending inclined from the main rail, the slider The rattling can be reduced, and the quality of the opening / closing body can be improved.

The driving force applied to the sunshade panel 5A is transmitted to the remaining sunshade panels 5B and 5C via the coupling mechanism 10.

  In FIG. 2, the connecting mechanism 10 is a cam mechanism in which the cam pins 18 are detachably fitted into the cam grooves 19. However, the sunshade panels (5A and 5B, 5B and 5C) are connected. A known structure may be used as long as it is a detachable mechanism. Since the connecting mechanism 10 is a requirement that departs from the spirit of the present invention, a detailed description thereof will be omitted.

An inclined rail 20 is attached to the rear end of the lower rail 8B so as to extend obliquely rearward and upward. The inclined rail 20 corresponds to the “inclined rail” recited in the claims, and the lower rail 8B corresponds to the “main rail” recited in the claims.
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.

The sliders to which the configuration of the present invention is applied are the rear sliders 7 </ b> C and 7 </ b> B that enter the inclined rail 20. Hereinafter, the case of the rear slider 7C will be described.
3 is an external perspective view showing the rear slider 7C and a spring mechanism 90 attached to the rear slider 7C in an exploded state, and FIG. 4 is an AA view of FIG. 3 with the spring mechanism 90 attached to the rear slider 7C. FIG. 5 is an explanatory side view when the rear slider 7C is positioned on the lower rail 8B, which is the main rail, and FIG. 6 is an explanatory side view when the rear slider 7C is positioned on the inclined rail 20. It is.

As shown in FIGS. 3 to 6, the shape of the rear slider 7C is a resin member having a substantially parallelogram when viewed from the side, and its lower surface 71 is a surface in surface contact with the bottom surface portion 81 of the lower rail 8B. The rear inclined surface 72 is a surface that is in surface contact with the bottom surface portion 21 of the inclined rail 20. The lower surface 71 of the rear slider 7C corresponds to a “first sliding surface” recited in the claims, and the rear inclined surface 72 corresponds to a “second sliding surface” recited in the claims.
Further, the upper surface 73 of the rear slider 7C is a surface facing the upper surface portion 82 of the lower rail 8B, and the front inclined surface 74 is a surface facing the upper surface portion 22 of the inclined rail 20.

  On the upper surface 73 and the front inclined surface 74 of the rear slider 7C, a concave groove 75 having a rectangular shape in plan view is formed. The concave groove 75 extends in the longitudinal direction of the rear slider 7C, and is a portion into which a spring mechanism 90 described later is fitted.

  The spring mechanism 90 includes a metal leaf spring 91 that is curved upward, and a resin-made pressing member 92 that is a plate-like member that is substantially the same as the upper opening of the groove 75 in plan view. It is configured. The leaf spring 91 is placed on the bottom surface of the concave groove 75, and the pressing member 92 is disposed on the upper surface of the leaf spring 91.

A protrusion 75A is formed at the center of the bottom surface of the concave groove 75 so as to enter below the curved portion of the leaf spring 91, and the protrusion 75A prevents the leaf spring 91 from being displaced.
Further, the concave groove 75 is formed with a front side locking part 75B and a rear side locking part 75C for locking the pressing member 92 so as not to be disengaged upward. Specifically, the front end portion of the concave groove 75 is formed with a front locking portion 75B on which the front end portion 92A of the pressing member 92 is caught, and the rear end portion 92B of the pressing member 92 is formed at the rear end portion of the concave groove 75. The rear side latching | locking part 75C which catches is formed.

  As described above, the spring mechanism 90 includes the pressing member 92 and the leaf spring 91 interposed between the pressing member 92 and the rear slider 7C. The rear slider 7C includes the lower rail 8B and the inclined rail. In the state of FIG. 4 that is not attached to 20, the upper surface portion 92C of the pressing member 92 pushed up by the repulsive force of the leaf spring 91 protrudes from the upper surface 73 and the front inclined surface 74 of the rear slider 7C. Yes. The upper surface portion 92C of the pressing member 92 is a portion that comes into contact with the upper surface portion 82 of the lower rail 8B or the upper surface portion 22 of the inclined rail 20.

  Next, the operation of the present invention will be described. As shown in FIG. 1, when the drive source 9 is driven from the state in which the sunshade panels 5A to 5C are fully closed, the sunshade is passed through the front slider 6A and the rear slider 7A by the pull operation of the push-pull cable 16. Panel 5A slides backward. At this time, the sunshade panel 5A presses the sunshade panel 5B rearward by the connecting mechanism 10, and similarly, the sunshade panel 5B presses the sunshade panel 5C rearward so that the sunshade panels 5A to 5C are integrated rearward. Slide to.

  At this time, as shown in FIG. 5, in the rear slider 7C positioned on the lower rail 8B, the lower surface 71 is in surface contact with the bottom surface portion 81 of the lower rail 8B, and the upper surface portion 92C of the pressing member 92 is It comes into contact with the upper surface portion 82 of 8B. The pressing member 92 is pushed upward by the leaf spring 91, and a repulsive force acts on the upper surface portion 82 of the lower rail 8B from the pressing member 92. Thereby, a reaction force acts on the rear slider 7C from the upper surface portion 82 of the lower rail 8B, and the lower surface 71 of the rear slider 7C is pressed against the bottom surface portion 81 of the lower rail 8B. Then, the lower surface 71 of the rear slider 7C stably comes into surface contact with the bottom surface portion 81 of the lower rail 8B, and rattling of the rear slider 7C located on the lower rail 8B is reduced.

  Further, as shown in FIG. 6, the rear slider 7 </ b> C rises along the inclined rail 20 from the rear end of the lower rail 8 </ b> B. FIG. 6 shows a state in which the rear slider 7C is raised to a predetermined position on the inclined rail 20 and stopped. At this time, in the rear slider 7 </ b> C, the rear inclined surface 72 is in surface contact with the bottom surface portion 21 of the inclined rail 20, and the front end portion of the upper surface portion 92 </ b> C of the pressing member 92 is in contact with the upper surface portion 22 of the inclined rail 20. Become. As a result, as in the case where the rear slider 7C is positioned on the lower rail 8B, a repulsive force acts on the upper surface portion 22 of the inclined rail 20 from the pressing member 92, and the rear slider 7C is inclined. A reaction force acts from the upper surface portion 22 of the rail 20, and the rear inclined surface 72 of the rear slider 7 </ b> C is pressed against the bottom surface portion 21 of the inclined rail 20. Then, the rear inclined surface 72 of the rear slider 7C stably comes into surface contact with the bottom surface portion 21 of the inclined rail 20, and rattling of the rear slider 7C located on the inclined rail 20 is reduced. The

Here, the closing operation of the sunshade panels 5A to 5C (FIG. 2) basically moves opposite to the movement at the opening operation, and the description thereof is omitted.
When the sunshade panels 5A to 5C are closed, similarly to the opening operation, when the rear slider 7C is positioned on the inclined rail 20, the spring mechanism 90 causes the rear inclined surface 72 of the rear slider 7C to be the bottom surface of the inclined rail 20. Pushing against the portion 21 reduces the rattling of the rear slider 7C (see FIG. 6). Further, when the rear slider 7C is positioned on the lower rail 8B, the lower surface 71 of the rear slider 7C is pressed against the bottom surface 81 of the lower rail 8B by the spring mechanism 90, and rattling of the rear slider 7C is reduced. (See FIG. 5).

  According to the slide structure of the sunshade panels 5A to 5C (FIG. 2) as described above, as shown in FIGS. 5 and 6, the rear slider 7C is positioned on the lower rail 8B by the spring mechanism 90 provided on the rear slider 7C. When the rear slider 7C is positioned on the inclined rail 20, the lower inclined surface 72 of the rear slider 7C is pressed against the bottom surface 81 of the lower rail 8B. It will be pressed against the bottom part 21. Thus, even when the surface contact portion of the rear slider 7C with respect to the guide rail 8 changes in the middle, the rear slider 7C always makes a stable surface contact with the guide rail 8, so that the rear slider 7C The rattling can be reduced.

  In the present embodiment, the rear slider 7C of the sunshade panel 5C shown in FIG. 2 has been described. However, the rear slider 7B of the sunshade panel 5B adjacent to the sunshade panel 5C has the same configuration as the rear slider 7C and has the same function. There will be an effect. Therefore, in the present invention, in the sunshade panels 5B and 5C configured such that the surface contact portions of the rear sliders 7B and 7C with respect to the guide rail 8 are changed in the middle, rattling of the rear sliders 7B and 7C is reduced. The quality of the sunshade panels 5A to 5C can be improved.

  Further, the spring mechanism 90 of the rear slider 7C functions to press the lower surface 71 of the rear slider 7C against the bottom surface portion 81 of the lower rail 8B, and functions to press the rear inclined surface 72 of the rear slider 7C against the bottom surface portion 21 of the inclined rail 20. Since it serves as a single unit, the rear slider 7C can have a simple structure.

  Moreover, durability of the spring mechanism 90 can be improved by making the leaf | plate spring 91 of the spring mechanism 90 metal. Furthermore, the manufacturing cost can be reduced by using the leaf spring 91 that is easy to process.

  The preferred embodiments of the present invention have been described above. In the described embodiment, as shown in FIG. 3, the pressing member 92 is pushed out by the leaf spring 91, but the elastic member for pushing out the pressing member 92 is not limited, and various known elastic members are used. be able to. Further, the pressing member 92 may be configured to be biased upward without providing an elastic member between the pressing member 92 and the rear slider 7C.
