Description

  The present invention relates to a sun visor device in which a sun visor body for light shielding can be manually stored on a ceiling.

  A vehicle such as an automobile is usually provided with a sun visor for light shielding. Some of these sun visors can be stored on the ceiling after use (see, for example, Patent Document 1).

  The sun visor device that can be stored in the ceiling as described above has a shape in which the sun visor body is convex upward in order to accommodate the angular difference between the nearly horizontal ceiling and the obliquely inclined front windshield glass. It is preferable to bend it.

  As a prior art of such a retractable sun visor device, a device in which a sun visor main body is fixed by, for example, pressure bonding by urging of a spring has already been disclosed (for example, see Patent Document 2). However, in the case of the structure using the biasing force of the spring, the crimping state of the fixing portion due to the biasing force of the spring becomes unstable due to vibration during traveling of the vehicle, and the holding force for securely fixing the sun visor body may be insufficient. .

  For this reason, it is desirable to set a lock mechanism that fixes the sun visor body at a predetermined pull-out position. Because the direction width fluctuates, especially in the method of fixing the vicinity of the center part in the vehicle width direction of the sun visor body, it is not possible to secure a sufficient space between the sun visor body and the ceiling, and it is not possible to arrange a lock mechanism between them. difficult.

Furthermore, in order to grip the operating part and manually operate the sun visor, the trajectory of the operating part also bends in accordance with the shape of the sun visor body, and in addition, the ceiling in the passenger compartment must also be curved. Since the track of the part is also curved in an arc according to the ceiling, the operability is lowered.

  As shown in FIGS. 1 to 3, an operation grip 20 formed in a flat, substantially rectangular parallelepiped shape is provided at the center of the rear end side of the sun visor body 12. A groove 48 having a predetermined groove width extending along the longitudinal direction of the vehicle body is formed at a position corresponding to the vertical direction of the vehicle body and the grip portion 20 for operation on the ceiling 40, and the grip portion 20 passes through the groove 48. Is arranged in a protruding state on the vehicle interior side. As shown in FIG. 3 (B), a pair of push buttons that can be pushed in from both the outside in the vehicle body width direction to the inside (in the direction of arrow C in FIG. 3 (B)) 22 is provided. In addition, these holding | grip part 20 and a pair of push button 22 are equivalent to the unlocking means in this invention.

  As shown in FIG. 3A, the pair of left and right push buttons 22 are respectively coupled to a pair of left and right lock bars 26 disposed between the ceiling 40 and the sun visor body 12. Specifically, each push button 22 is projected from the grip portion 20 to the outside in the vehicle width direction and pressed by the occupant with a finger, and the outer side of the press portion 22A on the inner side in the vehicle width direction of the press portion 22A. And a vertical wall 22 </ b> B standing in parallel to the wall and having a length penetrating the groove 48. 3A, the vertical wall 22B located on the left side penetrates the vicinity of the left edge of the groove 48, and its penetrating end is coupled to the lock rod 26 located on the left side. 3A, the vertical wall 22B located on the right side penetrates the vicinity of the right side edge of the groove 48, and its penetrating end is coupled to the lock rod 26 located on the right side. Further, the push button 22 located on the left side and the push button 22 located on the right side are arranged apart from each other by the pressing stroke, and the guide bar 23 is located on the left side from the vertical wall 22B located on the left side. A cylindrical guide tube 25 that receives the guide bar 23 is pushed on the right side of the vertical wall 22B of the push button 22 that extends in the pressing direction of the button 22 and is positioned on the right side. It is erected. In addition, a thin and narrow plate-like stopper 27 is formed at the center of the upper surface of the gripping part 20 to restrict the pressing stroke of the pair of left and right push buttons 22.

  Further, in the state shown in FIG. 3 (A), the upper end side surface of the vertical wall 22B of the push button 22 located on the left side is directed toward the vertical wall 22B of the push button 22 located on the right side disposed opposite thereto. An extended guide bar 29 is erected. The tip of the guide bar 29 is inserted into a guide hole 31 formed in the vertical wall 22B of the push button 22 located on the right side. A spring (compression coil spring) 28 is wound around the guide bar 29. Both ends of the spring 28 are in contact with and locked to the inner surfaces of the pair of left and right vertical walls 22B, and the left and right push buttons 22 and the left and right lock rods 26 are pressed and urged away from each other via the vertical walls 22B. is doing.

  On the other hand, the lock rod 26 is formed in the shape of an elongated square bar arranged with the vehicle body width direction as the longitudinal direction, and its axial length is the length from the outer surface of the vertical wall 22B of the push button 22 to the inner surface of the slide rail 14. Is set to Further, a lock protrusion 30 is formed on the outer end of the lock rod 26 in the longitudinal direction as a lock portion that is slightly thinner than the lock rod 26 on the same axis. As shown in FIG. 2, the lock protrusion 30 is selectively selected from any of lock holes 32A, 32B, 32C, 32D, and 32S as lock receiving portions formed in a straight line on the lower edge side of the slide rail 14. Is engaged (fitted). Accordingly, the spring 28 presses and urges the left and right push buttons 22 and the left and right lock rods 26 in the direction away from each other as described above, and the lock protrusion 30 is engaged with any one of the lock holes 32A to 32D and 32S. Pressing and biasing in the direction of mating. Since the lock holes 32A to 32D are used for adjusting the position of the sun visor body 12, the lock holes 32S are for holding the storage position of the sun visor body 12 whereas the lock holes 32S are formed at a predetermined pitch in the front portion of the slide rail 14. Therefore, it is formed at the rear end portion of the slide rail 14. Accordingly, the movement stroke of the grip 20 in the longitudinal direction of the vehicle body is a distance d from the rearmost lock hole 32S to the frontmost lock hole 32A.

  As shown in FIGS. 1 to 3, a guide rod 24 formed in a prismatic shape stands near the end of the lock rod 26 in the longitudinal direction (that is, near the inside of the slide rail 14) toward the upper side of the vehicle body. It is installed. Correspondingly, an engagement hole 34 as a rectangular engagement receiving portion into which the guide rod 24 can be inserted (freely fitted) is formed in the vicinity of both end portions in the width direction on the rear end side of the sun visor body 12. Yes. The opening width along the vehicle body width direction of the engagement hole 34 is set to a length obtained by adding the moving stroke of the lock rod 26 to the width direction dimension of the guide rod 24, and is usually moved outward by the biasing force of the spring 28. Is located. Further, the opening width of the engagement hole 34 in the longitudinal direction of the vehicle body is set to be substantially the same as the width of the guide rod 24. Therefore, when the grip 20 moves in the longitudinal direction of the vehicle body, the guide bar 24 interferes with the inner wall surface of the engagement hole 34, so that the sun visor body 12 moves integrally. Further, the height of the guide bar 24 is set so that the distance between the movement trajectory of the sun visor body 12 and the ceiling 40 is the longest (that is, the sun visor body 12 in the retracted position is half-stroked forward of the vehicle body to lock the protrusion 30. Is set to such a length that the engagement state with the engagement hole 34 can be maintained even when the lock hole 32D is engaged with the lock hole 32D.

  In the above configuration, the guide rod 24 and the lock rod 26 correspond to the guide member in the present invention, and the lock rod 26, the spring 28, the lock projection 30, and the lock holes 32A, 32B, 32C, 32D, and 32S are the main members. This corresponds to the locking means in the invention. The lock rod 26 is also a guide member and a lock means in the present invention.

  Next, the operation and effect of this embodiment will be described.

  The state indicated by the solid line in FIGS. 1 and 2 is a state in which the sun visor body 12 is held in the storage position. In order for the occupant to move the sun visor main body 12 to an arbitrary pull-out position from this state, first, as shown in FIG. 3 (B), the pressing portions 22A of the push buttons 22 provided on both sides of the grip portion 20 in the vehicle body width direction. The springs 28 are pressed in directions approaching each other against the biasing force of the spring 28 (the direction of arrow C in FIG. 3B). As a result, the left and right lock rods 26 connected via the vertical walls 22B of the left and right push buttons 22 are pulled in a direction approaching each other, and the lock protrusion 30 is released from the lock hole 32S corresponding to the storage position and locked. Is released. However, even if the locked state is released, the guide rod 24 remains engaged with the engagement hole 34. As a result, an operation of moving the grip 20 along the groove 48 of the ceiling 40 to the front side of the vehicle (in the direction of arrow F in FIGS. 1, 2, and 4) is possible.

  Next, after unlocking, the grip 20 is gripped without pressing the push button 22 and moved along the groove 48 of the ceiling 40 to the front side of the vehicle (in the direction of arrow F in FIGS. 1, 2, and 4). Then, the lock protrusion 30 is fitted into the lock hole 32 </ b> D by the biasing force of the spring 28. When it is desired to further pull out the sun visor body 12, the above operation is repeated, and the lock protrusion 30 may be fitted into any of the lock holes 32C, 32B, 32A. Incidentally, as shown by a two-dot chain line in FIGS. 4 and 2, when the lock protrusion 30 is fitted into the lock hole 32 </ b> A at the foremost end, the sun visor body 12 can be held at the full stroke position. Note that when the sun visor body 12 is returned to the retracted position direction (the direction of the arrow R in FIGS. 1, 2, and 4), the grip portion 20 may be gripped and moved to the rear side of the vehicle body in the same manner.

  As the lock projection 30 is fitted in the lock hole 32 as described above, the position of the grip 20 in the longitudinal direction of the vehicle body is fixed, so that the sun visor body 12 moves from the retracted position to the drawn position as shown in FIG. During this time, the lock protrusion 30 is fitted into each of the lock holes 32S to 32A provided on the slide rail 14, and the position of the grip 20 in the longitudinal direction of the vehicle body can be fixed.

  As a result, the lock bar 26 and the guide bar 24 that move in accordance with the movement of the gripper 20 can also be fixed in the longitudinal direction of the vehicle body for each of the lock holes 32S to 32A, so that the guide bar 24 is engaged. The position of the engagement hole 34 in the longitudinal direction of the vehicle body is also fixed by the lock holes 32S to 32A.

  If the position of the engagement hole 34 in the longitudinal direction of the vehicle body is fixed in the lock holes 32S to 32A, the position of the sun visor main body 12 is also fixed in the longitudinal direction of the vehicle body. As a result, the lock protrusion 30 is fitted in the lock hole 32. The sun visor main body 12 is also fixed in the longitudinal direction of the vehicle body every time they are combined.

  Here, in the present embodiment, as described above, the sun visor main body 12 is adjusted to the angle formed by the roof 44 and the front windshield glass 46 to avoid interfering with the front windshield glass 46 when it is at the extraction position. Since it is curved in a shape that is convex upward, if a grip portion for taking in / out operation is directly provided in the sun visor body 12, the grip portion also has a curved locus along the movement locus of the sun visor body 12. I will draw. Accordingly, the gripping portion interferes with the ceiling 40 and the passenger in the passenger compartment cannot operate. However, in this embodiment, since the guide rod 24 having a predetermined axial length is loosely fitted in the engagement hole 34, the engagement state of both is maintained even if the grip portion 20 is moved in the longitudinal direction of the vehicle body. Is done. Therefore, even when the occupant grips the grip 20 and moves it from the retracted position to the pulled-out position, the engagement position between the guide rod 24 and the engagement hole 34 provided in the sun visor body 12 (curved surface) is in the vertical direction of the vehicle body. The guide bar 24 always protrudes upward in the vehicle body (that is, the sun visor body 12) even if the occupant moves the grip 20 in the vehicle longitudinal direction along the ceiling 40. The sun visor body 12 can be moved in the front-rear direction of the vehicle body while engaging with the engagement hole 34 that moves along the locus of the shape. In other words, according to the present embodiment, the curved sun visor body 12 can be moved in the longitudinal direction of the vehicle body on the curved track while the movement direction of the grip portion 20 is a simple linear motion in the longitudinal direction of the vehicle body. .

  Thus, in this embodiment, even when the sun visor body 12 having a curved shape is operated to be taken in and out between the retracted position and the drawn position, the grip portion 20 can be moved linearly along the ceiling 40. There is no need to bend the ceiling 40 in accordance with the shape of the sun visor body 12, the design freedom of the ceiling 40 is increased, and the sun visor apparatus is excellent in holding power of the sun visor body 12 and has good operability. it can.

  Further, by adopting the above structure, the sun visor main body 12 can be firmly and accurately fixed as long as the strength of the lock hole 32 and the lock protrusion 30 allows, unlike the position fixing by the pressing force or friction by the spring. Can do.

  Further, the lock protrusion 30 and the lock holes 32S to 32A into which the lock protrusion 30 are fitted are provided on both outer sides in the vehicle width direction of the sun visor body 12, thereby providing a lock mechanism between the sun visor body 12 and the ceiling 40. There is no need, and space can be secured.

  Similarly, unlike the position fixing by the pressing force or friction by the spring, the configuration of the present embodiment prevents the position fixing of the sun visor body 12 from being inadvertently released due to the influence of the vibration of the vehicle. Therefore, even if the position of the sun visor main body 12 is securely fixed without being affected by the vibration of the vehicle or the vehicle is inclined in the vehicle longitudinal direction on a slope or the like, the vehicle is accelerated in the vehicle longitudinal direction during acceleration or deceleration. The position of the sun visor main body 12 can be fixed firmly and accurately in the same manner.
