  Next, an example of the assembly procedure of the in-vehicle display device (1) configured as described above will be described. First, before assembling the whole, the ratchet pawl (47) and the coil spring (51) are attached to the pendulum (38a) (38b) together with the sleeve (50) with the mounting screw (49). In addition, the base (17a) of the housing (8) includes a stopper (18) and a sleeve (25), a coil spring (26), a washer (29), and a washer (30) as well as a mounting member (19).

  Subsequently, the mainspring spring (39), the cam plate (55), and the spacer (60) are attached in this order from the lower side of the rotating shaft (3), and then the snap ring (34) is attached to the annular groove (36). These members (39), (55), (60), and (34) are attached below the flange (32) of the rotating shaft (3). At this time, the mainspring (39) engages one end (39a) with the positioning recess (61) of the rotating shaft (3) to rotate integrally with the rotating shaft (3).

  Further, as shown in FIG. 2, the screw (58) is screwed into the screw hole (59) of the cam plate (55), and the tip thereof is fastened to the circumferential surface of the rotary shaft (3). (3) is fixed so that it can rotate integrally. Thereby, the assembly of the lower part of the collar part (32) in the rotating shaft (3) is completed.

  Next, the ratchet gear (37), the spacer (62), the pendulum (38a), and the pendulum (38b) are mounted in this order from the upper side of the rotating shaft (3), and then the snap ring (33) is inserted into the annular groove (35). When these are attached, these members (37), (62), (38a), (38b), and (33) are attached at positions above the flange (32) of the rotating shaft (3).

  When the pendulum (38a) and the pendulum (38b) are attached, the pendulum (38a) and the pendulum (38b) are displaced from each other by 180 degrees as shown in FIG. Mounted rotatably.

  The ratchet pawls (47a) and (47b) attached to the pendulum (38a) and the pendulum (38b) respectively deflect the coil spring (51), and the ratchet pawl (47a) is a ratchet tooth on the outer periphery of the ratchet gear (37). (40) Escape from the outside, and after installation, the ratchet pawl (47a) abuts the ratchet teeth (40) of the ratchet gear (37) by the urging force of the coil spring (51), Located in the stop position.

  Thus, in the state where the ratchet pawl (47a) is in contact with the ratchet teeth (40) of the ratchet gear (37), the ratchet gear (37) can be rotated only in one direction by the ratchet pawl (47a). Be controlled.

  Thereafter, the other end (39b) of the mainspring spring (39) is fixed to the lower surface of the ratchet gear (37) by the bracket (54) and the mounting screws (52) (53), and the ratchet gear (37) rotates. By assembling the mainspring spring (39) so that the spring can be charged, the assembly on the rotating shaft (3) side is completed.

  Subsequently, the members incorporated in the rotating shaft (3) are mounted in the housing (8) so that the lower end side of the rotating shaft (3) protrudes downward through the hole (16). By this incorporation, the stopper (18) is brought into contact with the lower surface of the ratchet gear (37) by the urging force of the coil spring (26). The position where the stopper (18) abuts is within the rotation trajectory of the cam (43), and when the stopper (18) is not in contact with the cam (43), the stopper claw portion (18a ) Is located at a stop position where it engages with the locking step portion (56b) of the cam plate (55), and the main plate spring (39) is prevented from rotating in the biasing direction of the cam plate (55). That is, the rotation of the cam plate (55) is locked.

  When the stopper (18) corresponds to the maximum projecting position of the cam (43), the locking claw portion (18a) of the stopper (18) is moved to the release position outside the rotational locus of the cam (43), and The pawl portion (18a), the cam plate (55), and the locking step portion (56b) are disengaged, and the cam plate (55) can be rotated.

  Next, the substrate (7) is placed on the upper side of the housing (8), and from the lower side of the housing (8), the mounting screw (62) is attached to the screw hole (12) through the mounting hole (15), and the plate (7 ) And the housing (8) are fastened together, the assembly of the in-vehicle display device (1) shown in FIGS. 1 to 3 is completed.

  The vehicle display device (1) thus assembled is used by being attached to the lower surface of the ceiling of the vehicle. In this case, the vehicle display device (1) is mounted such that the longitudinal direction of the mounting plate (4) is perpendicular to the traveling direction of the vehicle. It should be noted that the two advertising media (5) and (5) are attached to the mounting plate (4) attached to the ceiling in a suspended state with their display surfaces facing each other back to back. preferable.

Next, the operation will be described.
Usually, the cam (43) provided on the lower surface of the ratchet gear (37) and the stopper (18) attached to the housing (8) are in positions not corresponding to each other, and the stopper (18) is a coil spring. Due to the urging force of (26), as shown by a solid line in FIG. 7, the urging force is rotated upward until the base end portion (28) contacts the locking pin (27).

  Further, the locking claw portion (18a) is rotated upward by the urging force of the coil spring (26) and is disposed in the rotation locus of the locking step portion (56b) of the cam plate (55). 3. A stop position that always engages with the locking step portion (56b) of the cam plate (55) urged clockwise in FIG. 3 and prevents the mainspring spring (39) from rotating in the urging direction. And restricts the rotation of the cam plate (55).

  The ratchet pawls (47a) and (47b) attached to the pendulums (38a) and (38b) are always urged clockwise in FIG. 3 by the spring force of the coil spring (51), and the ratchet teeth ( The ratchet pawl (47a) is engaged with the step formed between the tooth surfaces (40b) and (40b) of 40), and the ratchet gear (37) is urged by the mainspring spring (39) in FIG. The rotation in the counterclockwise direction is restricted and the ratchet gear (37) can be rotated only in the clockwise direction.

  FIG. 9 is a schematic diagram showing the operation of the pendulums (38a) and (38b) when the vehicle starts and stops, and when the vehicle accelerates and decelerates. FIG. 9 (a) shows when the vehicle is braked and stopped. The operation of the pendulums (38a) and (38b) in FIG. 4B shows the operation of the pendulums (38a) and (38b) when the vehicle starts. In the following description, the traveling direction of the vehicle is assumed to be upward in the drawing. When the vehicle is stopped, the pendulums (38a) and (38b) are normally stopped in contact with the base (17a) (FIG. 9 (9)).

  When the vehicle starts moving, inertial energy works backward, and the pendulums (38a) and (38b) start rotating in directions opposite to each other toward the base (17b). In this rotation, the pendulum (38a) rotates while the ratchet pawl (47a) is linked to the ratchet gear (37) and the ratchet gear (37) rotates clockwise in FIG.

  On the other hand, in the pendulum (38b), the ratchet pawl (47b) slides relative to the ratchet gear (37) and rotates without rotating the ratchet gear (37), and both the pendulum (38a) and the pendulum (38b) ) Until it reaches the state of FIG. 9B. Further, when the ratchet gear (37) rotates in the clockwise direction, the mainspring spring (39) is gradually wound up and charged by the spring to accumulate energy.

  On the other hand, when the vehicle is braked, inertial energy works forward, and the pendulums (38a) and (38b) start to rotate together toward the base (17a). At this time, the pendulum (38b) rotates while rotating the ratchet gear (37) in the clockwise direction in FIG. 3 with the ratchet pawl (47b) linked to the ratchet gear (37).

  On the other hand, in the pendulum (38a), the ratchet pawl (47a) slides relative to the ratchet gear (37), rotates without rotating the ratchet gear (37), and both the pendulum (38a) and the pendulum (38b) It rotates until it reaches the state of FIG.

  When the ratchet gear (37) rotates in the clockwise direction, the mainspring spring (39) is gradually wound and charged, and further accumulates energy.

  Subsequently, when the vehicle starts or accelerates again, inertial energy works backward, so that the pendulums (38a) and (38b) start to rotate together toward the pedestal (17b) and the ratchet gear ( 37) is rotated clockwise, and the mainspring spring (39) is spring-charged. Therefore, every time the vehicle starts / stops or accelerates / decelerates repeatedly, the ratchet gear (37) is rotated step by step, and the mainspring spring (39) is spring-charged for each rotation.

  In this example, the pendulums (38a) and (38b) are described as rotating until they come into contact with the pedestals (17a) and (17b). (17a) (17b) may rotate in small increments, but in this case as well, the ratchet gear (37) is rotated step by step, and the mainspring spring (39) is Charged.

  As described above, when the stepping rotation of the ratchet gear (37) progresses while the spring charge of the mainspring spring (39), that is, energy is accumulated, and the ratchet gear (37) rotates by a predetermined amount, ( As shown in a), the stopper (18) contacts the cam surface of the cam (43). Further, when the rotation of the ratchet gear (37) proceeds, the stopper (18) is gradually rotated and displaced downward by the shape of the cam (43), and as shown in FIG. When the energy stored in the mainspring spring (39) reaches a predetermined value immediately before the cam (43) is detached from the cam (43), as shown by a two-dot chain line in FIG. The pawl portion (18a) is disengaged from the locking step portion (56b) of the cam plate (55).

  As a result, the cam plate (55) rotates in the clockwise direction together with the rotating shaft (3) using the spring force accumulated in the mainspring spring (39), that is, the accumulated energy as a driving force. Further, the stopper (18) is immediately removed from the cam (4), and is rotated and displaced again upward. By this rotational displacement, the locking claw portion (18a2) returns to the position where it can be engaged with the locking step portion (56b) of the cam plate (55) again.

  When the cam plate (55) rotates 180 degrees, the locking claw portion (18a) is again engaged with the locking step portion (56b) of the cam plate (55), and the cam plate (55) is held in that position. Is done. By repeating this operation, the rotating shaft (3), together with the cam plate (55) and the mounting plate (4), repeats the operation of rotating 180 degrees and stopping. Is rotated in the direction and the front and back surfaces are reversed. Thereby, the user can see both sides of the advertising medium (5) without moving the place.

  Therefore, according to the in-vehicle display device (1) in the present embodiment, the advertisement medium (5) for displaying the printed matter printed on paper or the like in a suspended manner is until the vehicle starts and stops. The energy generated by the acceleration / deceleration operation repeated is stored in the energy storage means (9), the ratchet gear (37) is rotated by a predetermined amount of rotation, and when the energy reaches a predetermined value, the stopper (18) And the cam plate (55) are disengaged, and the mounting plate (4) and the advertisement medium (5) are rotated together with the rotary shaft (3) by the spring energy accumulated in the mainspring spring (39) until then. Automatically rotated degrees. Therefore, the user can see the double-sided advertisements at the same position, and the advertising effectiveness can be improved.

  In addition, since the energy used for rotation is inertial energy generated by acceleration / deceleration of the vehicle, maintenance costs can be reduced without using electricity or the like.

  In the above-described embodiment, the advertisement medium (5) has been described with respect to a structure that is rotated by 180 degrees. However, the rotation angle changes the number and position of the locking step portions (56b) provided on the cam plate (55). Can be changed. The advertising medium (5) may be a vertical or horizontal cylindrical body.
