Description

  The present invention relates to a sunshade device.

2. Description of the Related Art Conventionally, as a sunshade device particularly in a rear window for an automobile, for example, a configuration disclosed in Patent Document 1 is known in addition to a configuration in which a curtain wound around a spindle is developed on a window. The sunshade device disclosed in Patent Document 1 is a screen-up (manual) type rear sunshade device, in which a screen installed on a package tray jumps up by a spring hinge or the like to block light from the window glass. To do.
German Patent Application No. 10219610

However, in the sunshade device as disclosed in Patent Document 1, for example, the following problems may occur.
(1) Since the screen is installed on the package tray, when the height of the window glass is longer than the total length of the package tray, there may be a portion that cannot be shielded from light.
(2) Since the screen is held only by the spring force provided in the hinge, the screen may flutter (finely move) when traveling on rough roads.

  The present invention has been made to solve the above-described problems, and can increase the light-shielding area, and can provide light-shielding without leakage even to a window glass having a relatively large area. An object of the present invention is to provide a sunshade device that suppresses generation and hardly generates interference sound due to fluttering.

  In order to solve the above-described problems, a sunshade device according to the present invention is a sunshade device that unfolds a light shielding member on a window surface and shields the inside of the window, and the light shielding member is between a housed state and a used state. It is configured to be rotatable, and includes a light-shielding area variable means that can relatively reduce the light-shielding area in the housed state and can relatively increase the light-shielding area in the use state.

  According to such a sunshade device, since the light shielding area of the light shielding member can be changed by the light shielding area variable means, if the light shielding area is reduced in the storage state while the light shielding area is increased in the use state, a small space can be obtained. A large-area window can be shielded from the storage location. That is, a large-area window can be shielded from light regardless of the storage space. Therefore, even when the area (height) of the window is larger than the area (full length) of the storage place, by changing the area of the light shielding member, both wasteful storage and reliable light shielding can be achieved. It becomes possible. Further, the sunshade device of the present invention is of a type in which the light shielding member is rotated between the housed state and the used state, and the quality is higher than that of a winding curtain, and the thickness of the light shielding member is reduced. Since it is possible to design freely, it is natural that the range of the light shielding property to be applied is widened, and it is also possible to have a sound insulating property.

  In the sunshade device of the present invention, the light shielding member shields the rear window of the vehicle in the use state, and is housed on the vehicle package tray side in the housed state, and one end thereof is on the vehicle rear side of the package tray. The other end of the package tray can be turned as a free end on the vehicle front side.

  As described above, if the light shielding member is pivotally supported on the rear side (the side closer to the window of the package tray) of the vehicle package tray and the free end is rotated on the front side (the side away from the window of the package tray), When the light shielding member is rotated, the window does not get in the way, and the operation is simple. Further, for example, when one end of the light shielding member is pivotally supported on the front side of the package tray in the vehicle, the vehicle interior may be narrowed by blocking the rear from the pivotal support position in the usage state. By pivotally supporting the rear side, a space is created on the front side in use, and effective use of the space can be realized.

  The light shielding member may be configured to be placed on a predetermined position of the vehicle package tray in addition to being configured to be stored at a predetermined position in the vehicle package tray in the stored state. From the viewpoint of appearance design and space utilization, it is preferable that the storage state be integrated or substantially integrated with the tray.

  Moreover, the sunshade apparatus of this invention WHEREIN: The said light-shielding member shall be equipped with the rotation stop means which can stop the said rotation in the said use condition.

  According to such a sunshade device, it is possible to prevent the occurrence of a problem that the light shielding member rotates in the use state. Therefore, it is possible to prevent the occurrence of a problem that the light shielding member returns to the housed state during use and the light shielding is removed. In addition, the rotation stopping means can prevent or suppress the occurrence of fluttering (fine movement) of the light shielding member during traveling.

  In the sunshade device of the present invention, the light shielding member includes a first light shielding member and a second light shielding member, and one end of the first light shielding member is pivotally supported to enable the rotation. The two light-shielding members are attached to the first light-shielding member so as to be relatively movable between a superimposed state and a non-superimposed state, and the light-shielding area varies depending on an overlapping area between the first light-shielding member and the second light-shielding member. It is characterized by that. Here, the superimposed state and the non-superimposed state are states in which the overlapping degree is relatively separated, and the superimposed state is a state in which the first light shielding member and the second light shielding member are completely overlapped, as well as a non-superimposed state. The state where the overlapping area is larger than the state where the first light shielding member and the second light shielding member do not completely overlap, and the state where the overlapping area is smaller compared to the overlapping state. And

  According to such a sunshade device, the first light shielding member and the second light shielding member can simply configure the light shielding area variable means, and these can be moved relative to each other between the superimposed state and the non-superimposed state. The light shielding area of the light shielding member made up of two members will change. Specifically, when the two members are in the overlapping state, the light shielding area of the light shielding member is reduced in the overlapping portion, so that it is suitable for the storage state, while when the two members are in the non-overlapping state, Since there is no overlapping part (or few), the light shielding area of the light shielding member is increased, which is suitable for use.

  Further, in the sunshade device of the present invention, the light shielding member is configured to be foldable, and the light shielding area can be changed depending on the degree of fold.

  According to such a sunshade device, the light shielding area variable means can be easily realized by the folding configuration, and the light shielding area can be changed depending on the degree of the folding. Specifically, in the folded state, the light shielding member has a relatively small light shielding area and is suitable for the accommodation state. Therefore, it is suitable for use.

  In the sunshade device of the present invention, a locking means for locking the free end of the light shielding member in the use state may be disposed above the window.

  By such a locking means, it is possible to prevent or suppress the occurrence of fluttering (fine movement) of the light-shielding member in use, and particularly it is possible to suitably prevent the generation of vibration noise during traveling. In addition, the said latching means is good also as what also has the said rotation stop means.

  According to the present invention, it is possible to increase the light-shielding area and to provide light-shielding without leakage even for a window glass having a relatively large area. In addition, it is possible to provide a sunshade device that suppresses the fluttering of the light shielding member, which is a component component, and is unlikely to generate interference sound due to the fluttering.

Hereinafter, an embodiment of a sunshade device of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram showing a schematic configuration of a rear side surface of a vehicle including the sunshade device of the present embodiment, and FIG. 2 is a perspective view of FIG. 3 is a plan view showing the main part (configuration of the screen 15) of the sunshade device, and FIG. 4 is a cross-sectional view showing the main part (configuration of the screen 15) of the sunshade device. Further, FIG. 8 is a side sectional view showing a main part (rotating mechanism of the screen 15) of the sunshade device, and FIG. 9 is a perspective view showing a main part (locking structure of the screen 15) of the sunshade device.

  In FIG. 1, a package tray 30 is disposed on the rear upper part of a rear seat S on which a passenger M can be seated, and a sunshade device 10 is attached on the package tray 30. Here, the sunshade device 10 is composed of a cloth screen (light-shielding member) 15 as shown in FIG. 3, and by deploying the screen 15 along the vehicle rear window (rear window) W surface, The inside and outside of the window W are shielded from light.

  The screen 15 is configured to be rotatable with respect to the package tray 30. Specifically, one end of the substantially rectangular screen 15 is pivotally supported on the package tray 30 by the hinge 20, and is housed on the package tray 30 side in a state substantially parallel to the package tray 30, It is assumed to rotate between a use state developed along the plane of the window W in a state substantially parallel to the window W (in FIG. 1 and FIG. 2, an arrow Y1 indicates a rotation direction). A hook 13 for locking the screen 15 to the vehicle roof 40 is provided at the other end portion of the screen 15 (an end portion on the side opposite to the end portion supported by the shaft; a free end).

  As shown in FIG. 8, the hinge 20 is assembled in the package tray 30, and the hinge 20 is provided with an elastic member (spring) 21 for urging the screen 15. The screen 15 is connected to the connection member 24 via the bracket 22 and is urged by the elastic member 21 toward the window W (that is, toward the use state). Further, the hinge 20 is provided with a rotation stopping means 23 for stopping the rotation when the screen 15 is rotated by a predetermined angle so that the screen 15 does not collide with the window 15 by the biasing force. Yes. Here, the rotation stopping means 23 is constituted by a notch portion 26 of the casing 27 of the hinge 20 and a stopper 25 provided on the connecting member 24, and the stopper 25 of the connecting member 24 that connects the screen 15 and the elastic member 21 is provided. The rotation is stopped by contacting (entering) the notch 26.

  On the other hand, the sunshade device 10 can change the light-shielding area (here, the area of the screen 15) with respect to the window W between the above-described storage state and use state. Specifically, as shown in FIGS. 3 and 4, the cloth screen 15 includes a first screen (first light shielding member) 11 and a second screen (second light shielding member) 12. When the screen 11 and the second screen 12 move relative to each other, the degree of overlap between them changes, and the entire light shielding area of the screen 15 changes. That is, the light shielding area of the entire screen 15 changes depending on the overlapping area of the first screen 11 and the second screen 12, and the light shielding area of the screen 15 is in a state where the first screen 11 and the second screen 12 completely overlap each other. In contrast, when the first screen 11 and the second screen 12 are relatively moved from the overlapped state and the overlap is reduced, the light-shielding area is increased, and the overlap is finally eliminated (or the first screen 11). In a state in which the overlap with the second screen 12 is minimized), the light shielding area of the screen 15 is maximized.

  In the present embodiment, when the screen 15 is stored on the package tray 30 side (stored state), the first screen 11 and the second screen 12 are overlapped, and the light shielding area is minimized (FIG. 1). reference). On the other hand, in the use state in which the screen 15 is rotated to the window W side, the first screen 11 is moved relative to the second screen 12 by sliding, so that the first screen 11 and the second screen 12 overlap. By releasing, it is possible to increase the light shielding area of the entire screen 15 (in FIG. 1 and FIG. 2, the arrow Y2 indicates the sliding direction). Specifically, the first screen 11 and the second screen 12 reach a position where the overlapping area is minimized, that is, at a position where the first screen 11 is slid away from the second screen 12 to the maximum extent. Thus, the entire window W can be covered.

  The vehicle roof 40 is provided with a stopper (locking means) 41 (see FIGS. 1 and 9). When the screen 15 is rotated and the first screen 11 is slid from the second screen 12 and deployed, the hook 13 provided at the tip of the first screen 11 (screen 15) is placed behind the vehicle roof 40. By engaging with the provided stopper 41, the rotation of the screen 15 and the sliding of the first screen 11 can be stopped. In addition, the engagement prevents or suppresses the occurrence of fluttering of the screen 15 during vehicle travel.

Next, the relative movement (light-shielding area varying means) between the first screen 11 and the second screen 12 described above is realized by the following configuration.
That is, for example, as shown in FIGS. 3 and 4, the slide portion 11 b formed on the outer frame 11 a of the first screen 11 slides on the rail portion 12 b formed on the outer frame 12 a of the second screen 12. The relative movement between the first screen 11 and the second screen 12 is realized.

  The outer frame 11a of the first screen 11 is made of an aluminum frame-like member, and a cloth member is stretched in the frame. Further, the outer frame 11a constitutes a slide portion 11b made of a plate piece, and is configured to be slidable within the rail portion 12b of the second screen 12.

  The outer frame 12a of the second screen 12 is made of an aluminum frame-like member, and a cloth member is stretched in the frame. Further, the outer frame 12a constitutes a rail portion 12b having a U-shaped cross section, and the slide portion 11b of the first screen 11 is slidable in the rail. In addition, the felt 14 is arrange | positioned as a buffer member on the inner surface of the rail part 12b, and it contributes to the frictional force reduction of the said rail part 12b and the slide part 11b.

  The relative movement between the first screen 11 and the second screen 12 is realized by the sliding between the slide portion 11b and the rail portion 12b as described above. Note that the relative movement is not limited to the above configuration, and can be realized by the configuration shown in FIG. 5 or the configuration shown in FIGS. 6 and 7, for example.

  FIG. 5 is a cross-sectional view showing a first modification of the slide mechanism (relative movement mechanism) shown in FIGS. 3 and 4, and FIGS. 6 and 7 show a second modification of the slide mechanism (relative movement mechanism). It is the axial sectional view and side sectional view which show.

  In the slide mechanism shown in FIG. 5, relative movement is realized by the roller 16 fixed to the first screen 11 rotating on the second screen 12 side. Specifically, the outer frame 12d of the second screen 12 has a rail portion 12e having a U-shaped cross section, and the roller 16 is rotatable in the rail portion 12e. On the other hand, the outer frame 11d of the first screen 11 is configured as a plate-shaped piece having a substantially L-shaped cross section, and a roller fixing portion 11e formed by perforating the plate-shaped piece in the thickness direction is formed at the end. Has been. The roller 16 is fixed to the first screen 11 side by inserting the axle of the roller 16 into the roller fixing portion 11e and fixing the axle.

  In the slide mechanism having such a configuration, when the first screen 11 is slid, the roller 16 rotates in the rail portion 12e of the outer frame 12d of the second screen 12, and the rotation of the roller 16 causes the first screen 11 to move. The second screen 12 is slidable.

  Next, in the slide mechanism shown in FIGS. 6 and 7, relative movement is realized by the pinion 17 fixed to the first screen 11 rotating on the second screen 12 side. Specifically, the outer frame 12d of the second screen 12 has a rail portion 12e having a U-shaped cross section, and a rack 18 composed of peaks and valleys is further formed in the rail portion 12e. The pinion 17 is configured to be rotatable. On the other hand, the outer frame 11d of the first screen 11 has a pinion fixing portion 11e formed by perforating the side of the outer frame 11d facing the outer frame 12d of the second screen 12, and the pinion fixing portion 11e. The pinion 17 is fixed to the first screen 11 side by inserting the axle of the pinion 17 and fixing the axle.

  In the slide mechanism having such a configuration, when the first screen 11 is slid, the pinion 17 rotates on the rack 18 in the rail portion 12e of the outer frame 12d of the second screen 12, and the rotation of the pinion 17 is rotated. The first screen 11 is slidable with respect to the second screen 12 by movement. In addition, according to such a slide mechanism using the pinion 17, since the slide width (pitch) can be made equal in each of the left and right outer frames of the first screen 11, it is possible to realize a smooth slide. .

  According to the sunshade device 10 of the present embodiment as described above, since the light shielding area of the screen 15 can be changed, it is possible to reduce the light shielding area in the housed state and to increase the light shielding area in the used state. . Therefore, it is possible to shield the window W having a large area from a small storage space (here, on the package tray 30). In other words, the large-area window W can be shielded from light regardless of the storage space. In particular, when the sunshade device 10 of the present embodiment is used, it is possible to provide suitable light shielding properties not only for a hatchback type having a relatively small rear window length, but also for a sedan type vehicle having a large rear window length. Become.

  As a result, even when the area (height) of the window W is larger than the area (full length) of the storage place (on the package tray 30), the storage of the screen 15 can be performed without changing waste. And reliable shading can be achieved. In this embodiment, since the screen 15 is rotated between the housed state and the used state, the quality of the screen 15 is higher than that of light shielding by a winding curtain, for example. The thickness can be changed variously, the width of the light shielding property to be applied can be widened, and the sound insulating property can also be imparted.

  In the above-described embodiment, the screen 15 is pivotally supported on the rear side (the side near the window W of the package tray 30) of the vehicle, and freely on the front side (the side away from the window W of the package tray 30). Since the end (end opposite to the side on which the shaft is supported) is configured to rotate, the window W does not get in the way when the screen 15 is rotated, and the operation is simple. In addition, if one end of the screen 15 is pivotally supported on the front side of the package tray 30 in the vehicle, the rear side may be blocked from the pivotal support position in the use state, and the interior space may be narrowed. By pivotally supporting the rear side of the vehicle, a space is formed on the front side in the use state, and the space can be effectively used.

  In the above embodiment, the light shielding area is changed by the slide mechanism. For example, as shown in FIG. 10, the screen 50 is configured to be foldable into two or more, and the light shielding area is changed depending on the degree of fold of the screen 50. The thing of the structure to change can also be employ | adopted.

  FIG. 10 is a drawing (side view, perspective view) corresponding to FIGS. 1 and 2, respectively. In this case, the screen 50 is configured to be foldable in two stages by providing two folding portions (for example, hinges) 51a and 51b. In the housed state, the screen 50 is folded and the light shielding area is minimized, while in the use state, the screen 50 is unfolded and the light shielding area is maximized for light shielding. .

As mentioned above, although embodiment of this invention was described, this invention is not restricted to the said embodiment, The following aspects are also contained in this invention.
(1) Although the screen 15 (50) is configured to be placed on the package tray 30 in the storage state, the screen 15 (50) may be configured to be stored inside the package tray 30. In any case, the package tray 30 is acceptable. It is preferable that the storage state be integrated or substantially integrated.
(2) Although a cloth product having a light shielding property is used as the screen 15 (50), a resin plate member having a light shielding property or the like may be used. It doesn't matter.
(3) The sliding of the screen 15 is configured to slide two members in a one-stage manner, but a configuration in which a screen of three or more members is slid in a two-stage manner or more may be employed. Further, the screen 50 is folded in two stages, but may be folded in three stages or more.
(4) The screen 15 (50) may have a sound insulating property in addition to the light shielding property.
(5) In the screen 15, the first screen 11 is accommodated between the outer frames 12d on both sides of the second screen 12, the first screen 11 is set as the slide side, and the second screen 12 is set as the fixed side. The first screen 11 may be the fixed side, and the second screen 12 may be the slide side.
