Description

  The present invention relates to a vehicular visual recognition device for a vehicle, and more particularly to a vehicular visual recognition device for a vehicle having a visual recognition window provided on a vehicle body for visual recognition of the outside of a vehicle from a driver's seat and a louver device disposed in the visual recognition window. Is.

  2. Description of the Related Art Conventionally, an automobile is provided with a vehicle exterior visual recognition device for visually recognizing the exterior of a vehicle that can be a blind spot when viewed from the front, rear, left, and right windows provided on the upper side of the vehicle when turning left or reverse. A side mirror or the like is provided to make it possible to visually recognize such a blind spot, and in order to further assist the visual recognition by the side mirror, for example, the outer side portion of the side of the passenger seat when turning left can be visually recognized from the driver's seat. For this reason, there is a type in which a viewing window is provided in the lower part of the passenger seat door.

  However, the above-described viewing window provided on the passenger seat side is effective for visually confirming when making a left turn, but there is a problem that the inside of the vehicle can be seen from the outside when the vehicle stops or goes straight. In order to solve such problems, for example, there is a shutter that can be opened and closed in a viewing window, and the shutter is opened only when necessary when turning left, so that an invisible part when turning left is visible (for example, patents). Reference 1).

  On the other hand, when the viewing window as described above is provided in the lower part of the door, it is difficult to avoid the position of the viewing window from interfering with the raising / lowering range of the door glass. In some cases, a viewing window glass is provided, and an inner viewing window glass is provided on an inner panel of the door so that the door glass can be moved up and down in a space between both viewing window glasses. In that case, there is a possibility that the surfaces inside the doors of both viewing window glasses may become dirty due to dripping of water adhering to the door glass, etc., and cleaning of the surfaces inside the doors of both viewing window glasses is required. There is one in which the inner viewing window glass can be opened and closed by a hinge (for example, see Patent Document 2).

  In the thing of the said patent document 1, although it can prevent looking into from the outside, the vehicle-side visual recognition window glass and the vehicle-inside visual recognition window glass are fitted and killed by the door, and both windows are dripped by dripping water etc. There is a problem in that it cannot be cleaned when the surface inside the door becomes dirty.

  On the other hand, in the thing of the said patent document 2, the vehicle inside visual recognition window glass can be opened and closed, and the surface inside the door of the visual recognition window glass can be cleaned. However, when the louver device is attached to the vehicle interior viewing window glass to prevent peeping from the outside of the vehicle, if the interval between the plurality of slats provided in the louver device is narrow, a hand is inserted between the slats. There was a problem that it was difficult to clean the glass surface.

  Although it is possible to cope with this by expanding the space between the slats, in that case, in order to completely shield the viewing window when fully closed, the size of one slat increases, In order to be able to rotate, the distance between the two viewing window glasses becomes large, and another problem arises that it is disadvantageous to make the door thin (widening the vehicle interior).

In order to solve such a problem and to make it possible to easily clean the visual window in the vehicle exterior visual recognition device provided with the louver device without increasing the thickness of the door, in the present invention, A viewing window (3) provided in the vehicle body (1) for visually recognizing the outside of the vehicle from the driver's seat, a louver device (6) disposed on the vehicle interior side of the viewing window, and a vehicle with respect to the viewing window A transparent plate (24) provided via a hinge (25) so as to be openable and closable inside, and engaging the transparent plate by superimposing the louver device on the transparent plate, and the louver device the engagement releasable engagement member (28, 29) is provided integrally with the louver device to detach from the transparent plate, said engaging member is engaged with the edge portion of the transparent plate (24) The outer part of the louver device (6) An elastically deformable elastic engagement member (28, 29) extended, and the opening and closing direction of the transparent plate (24) is about the vertical axis of the vehicle body, and the elastic engagement member (28, 29). ) Are provided at a plurality of locations of the louver device (6) so as to engage with the respective upper and lower edge portions of the transparent plate, Engaging claws (28a, 29a) projecting toward the inner side of the transparent plate are provided on the side opposite to the louver device (6) of the transparent plate (24), and are provided on the upper edge of the transparent plate. The protruding length of the engaging claw (28a) to be engaged is longer than the protruding length of the engaging claw (29a) engaged with the lower edge portion of the transparent plate .

  According to this, since the louver device is detachably attached to the transparent plate that can be opened and closed inside the viewing window, the side of the transparent plate to which the louver device is attached can be removed by removing the louver device from the transparent plate. Can be cleaned without any problems. The transparent plate can be opened and closed, and the surface on the closed side (the vehicle outer side) of the transparent plate can be easily cleaned.

  In particular, the elastic engagement members (28, 29) extended from the outer peripheral portion of the louver device (6) so that the engagement member is elastically deformed and engaged with the edge portion of the transparent plate (24). It is good to consist of. According to this, the elastic engagement member is deformed (bent) to get over the edge portion of the transparent plate, and then the elastic engagement member is engaged with the edge portion of the transparent plate by the elastic restoring force. The louver device can be detachably attached to the transparent plate with a simple structure. Further, when the elastic engagement member is engaged on the back side of the transparent plate with the transparent plate closed, it is difficult to deform the elastic engagement member in order to release the engagement of the elastic engagement member. However, the transparent plate can be opened, and in the opened state, the back side of the transparent plate can be easily accessed, and the operation of releasing the engagement state of the elastic engagement member can be easily performed.

  Further, the opening and closing direction of the transparent plate (24) is about the vertical axis of the vehicle body, and the elastic engagement members (28, 29) are engaged with the upper and lower edge portions of the transparent plate. It is good to be provided at a plurality of locations of the louver device (6). When the opening and closing direction of the transparent plate is about the vertical axis of the vehicle body, it is elastic when the transparent plate is opened by gripping the louver device if the elastic engagement member is engaged with the left and right side edges of the transparent plate. Although there is a possibility that the engagement member may be disengaged, the louver device is engaged at the upper and lower portions, whereby the weight of the louver device is applied to the engagement portion of the upper elastic engagement member, and the louver device is detached from the transparent plate. It becomes difficult. Also, when the elastic engagement member is bent in the direction away from the transparent plate to release the engagement, the hinge side of the transparent plate and the vehicle body component (panel or interior material) )), It is difficult to remove the gap between the upper and lower portions. However, the engagement at the upper and lower portions does not have the above-mentioned inconvenience on the hinge side, and the engagement releasing operation is facilitated.

  Moreover, it protrudes toward the inner side of the said transparent plate in the extension direction edge part of the said elastic engagement member (28 * 29) in the opposite side to the said louver apparatus (6) of the said transparent plate (24). An engagement claw (28a, 29a) is provided, and the protruding length of the engagement claw (28a) that engages with the upper edge portion of the transparent plate engages with the lower edge portion of the transparent plate. It may be longer than the protruding length of the nail (29a). When engaging the upper and lower edge portions of the transparent plate, the lower elastic engaging member is lowered with respect to the lower edge portion of the transparent plate by the weight of the louver device. The length of engagement becomes shorter and it becomes easier to come off. On the other hand, the engagement claw with respect to the upper edge portion of the transparent plate comes to engage more greatly, and the engagement length of the engagement claw is long. Engagement becomes stronger and the louver device can be prevented from coming off. Even if there is a difference in the length of engagement between the upper and lower sides, when attaching the louver device, the louver device is slanted so that the lower side of the louver device is away from the transparent plate, and the upper side is first engaged. By tilting the lower side of the louver device so as to approach the transparent plate with the engaging portion as a fulcrum, the length of the lower engaging claw is short, so that the elastic engaging member is engaged without being greatly bent. The louver device can be easily attached.

  An interior member (31) having an opening (22a) having substantially the same shape as the exterior of the viewing window is provided inside the viewing window (3), and the interior member has the opening at the deepest portion. It is preferable that the louver device (6) is housed in the recessed portion. According to this, since the louver device is disposed in the recessed portion formed in the interior member, the louver device can be prevented from projecting from the vehicle inner surface of the interior member to the vehicle inner side, and the louver device is provided. In addition, it is possible to improve the aesthetics of the inside of the vehicle, and to prevent the louver device from hitting an occupant or a load. The louver device can be surrounded by the inner peripheral wall surface of the recessed portion, and even if the louver device is likely to come off from the transparent plate due to its own weight, it can be supported by the lower wall surface, for example. It is possible to prevent the device from coming off.

  In addition, when the transparent plate (24) is in a closed state, the protruding length of the engaging claw (28a) of the elastic engagement member (28) that engages at least with the upper edge portion of the transparent plate is the transparent plate. It is good if it is longer than the clearance gap between the edge part on the top and the part which the said recessed part (31a) opposes. As a result, in the closed state of the transparent plate (use state of the louver device), the length of the engaging claw is longer than the gap between the upper edge portion of the transparent plate and the opposite portion of the recessed portion. Even if the claw is about to come off, it strikes against the opposing portion of the recessed portion, and the elastic engagement member cannot be deformed any further, so that the engagement claw can be prevented from coming off. This is particularly effective in the upper elastic engagement member that supports the weight of the louver device, but it can be further prevented from coming off by being applied to the lower elastic engagement member.

  The inner wall surface of the recessed portion (31a) may be formed so as to expand from the opening (22a) toward the vehicle interior side. According to this, since the space | interval of the edge part of a transparent plate and the wall surface corresponding to the inner peripheral wall of a recessed part expands as a transparent plate is opened, the elastic engagement member currently engaged with the edge part of a transparent plate A space that can be greatly deformed is generated, the engagement of the elastic engagement member is easily released, and the louver device can be easily attached and detached. In addition, even when the louver device is attached to the transparent plate in the open state, even if the position of the louver device is slightly deviated from the transparent plate, by closing the transparent plate, the wall surface of the inner peripheral wall of the expanded shape of the recessed portion Thus, the louver device is guided, and the louver device can be placed in a predetermined position.

  The viewing window (3) includes a vehicle exterior window member (3a) provided on the door (2) of the vehicle body (1) and on the vehicle exterior side of the door, and the transparent plate (24 ) Is provided on the vehicle interior side of the door through a space between the vehicle exterior window member, and the door glass of the door is disposed so as to move up and down between the vehicle exterior window member and the transparent plate. The louver device may be attached to the inner side of the transparent plate. According to this, since the door glass moves up and down between the vehicle outer window member provided on the door and the vehicle inner transparent plate, and the louver device is attached to the vehicle inner side of the transparent plate, Interference between the glass and the louver device is avoided. In addition, the louver device can be prevented from being contaminated by water or the like dripping between the vehicle exterior door member and the transparent plate.

  As described above, according to the present invention, the louver device can be removed from the transparent plate, and by removing the louver device, the surface of the transparent plate to which the louver device is attached can be cleaned without any problems, and the transparent plate can be opened and closed. Since it is possible, the surface of the transparent plate on the closed side (vehicle outer side) can be easily cleaned by opening.
