  However, in this case, if you want to change the height position of the tonneau board, you must first pull the tonneau board completely from the currently supported slide rail and then fully insert it into the desired height slide rail. As a result, the pull-out distance and the insertion distance become longer and the work becomes cumbersome. In addition, when the tonneau board is pulled out, the entire weight of the tonneau board must be supported by hand, which makes it difficult to work. was there.

  The present invention was developed in view of such circumstances, and the invention according to claim 1 is a mechanism for vertically moving a deck board disposed on a floor panel of a deck room provided at the rear of an automobile, A first center of rotation is provided on both side walls of the storage room defined between the floor panel and the deck board, and a second center of rotation is provided on each side of the deck board corresponding to the first center of rotation. The second rotation center is connected via a link arm, and the rotation of the link arm moves the deck board between a lower position along the floor panel and an upper position covering the opening of the storage chamber. Features.

  The invention according to claim 2 is based on the premise of claim 1 and is provided with an elastic biasing means between the side wall of the storage chamber and the deck board or the link arm, and the deck board is moved by the biasing force of the elastic biasing means. When the second rotation center is rotated beyond the dead point of the elastic biasing means with respect to the first rotation center, the biasing direction is reversed. It is characterized by that.

  According to a third aspect of the present invention, on the premise of the first or second aspect, a shelf for placing a deck board is provided at the front upper end and the rear upper end of the storage chamber.

  In the invention according to claim 7, since the link arm is housed in the space defined between the inner side wall and the outer side wall, the link arm is not exposed to the outside and the appearance is improved. At the same time, there is no worry about the link arm being damaged by the load.

  The present invention presupposes a mechanism for moving up and down a deck board disposed on a floor panel of a deck room provided at the rear of an automobile, on both side walls of a storage room defined between the floor panel and the deck board. A first rotation center is provided, a second rotation center is provided on both sides corresponding to the deck board, the first rotation center and the second rotation center are connected via a link arm, and the link arm With this rotation, the deck board is easily moved up and down by moving it between a lower position along the floor panel and an upper position covering the opening of the storage chamber.

  Hereinafter, the present invention will be described in detail based on preferred embodiments illustrated in the drawings. First, the deck board vertical movement mechanism according to the first embodiment was developed as a mechanism for vertically moving the deck board B arranged on the floor panel P of the deck room R provided at the rear of the automobile. With respect to the storage room 1 defined between the panel P and the deck board B, the deck board B is easily positioned between the lower position along the floor panel P and the upper position covering the opening of the storage room 1. It is intended to be moved.

  Specifically, the vertical movement mechanism according to the first embodiment is provided on both side surfaces of the storage chamber 1 defined between the floor panel P and the deck board B as shown in FIGS. A base plate 2 to be fixed, a bracket 3 fixed to the back surface of the front end side of the deck board B, a link arm 4 pivotally supported on the base plate 2, and a movable upper end of the link arm 4 4a and the rotation pin 5 that connects the bracket 3; a collar 7 that is externally fitted to the intermediate portion of the rotation pin 5; and an elastic bias that is mounted between the base plate 2 and the protruding tip 5a of the rotation pin 5. A tension coil spring 8 as means is provided.

  The base plate 2 fixed to both side walls of the storage chamber 1 with screws or the like rotates the fixed-side base end portion 4b of the link arm 4 at the center thereof via the shaft 9 serving as the first rotation center. An arcuate circumferential groove 10 centered on the shaft 9 is formed on one side, and an end of the tension coil spring 8 is locked on the other side. The stopper 11 is configured to be folded back on the back side.

  The bracket 3 fixed to the back surface of the front end side portion of the deck board B via screws or the like is provided with the bearing portions 12 of the rotating pin 5 serving as the second rotation center on both sides thereof in a paired relationship, The intermediate portion of the rotary pin 5 is connected to the movable upper end portion 4a of the link arm 4 with the collar 7 interposed therebetween, and the tip end side of the rotary pin 5 is slid in the circumferential groove 10 of the base plate 2 described above. It has become.

  The link arm 4 connecting the first rotation center and the second rotation center has a movable upper end 4a that rotates along the peripheral groove 10 of the base plate 2 with the rotation pin 5. However, the movable-side upper end portion 4a to which the rotation pin 5 serving as the second rotation center is coupled is set so as to avoid the vicinity immediately above the shaft 9 serving as the first rotation center on the base plate 2 side. Accordingly, if the rotation pin 5 serving as the second rotation center is directly above the shaft 9 serving as the first rotation center, the link arm 4 cannot rotate but receives all loads, but the link Since the movable side upper end 4a of the arm 4 is set so as to avoid the position directly above the shaft 9, the link arm 4 can be rotated and the deck board B can be smoothly moved in the lower position direction.

  The rotating pin 5 supported by the bearing portion 12 of the bracket 3 has a tip portion 5a protruding from the circumferential groove 10 of the base plate 2 to the back surface side, and the other end portion of the tension coil spring 8 is connected to the protruding tip portion 5a. It is configured to be locked. Therefore, normally, the rotation pin 5 is urged to either the lower position or the upper position of the deck board B by the urging spring pressure of the tension coil spring 8, but the second rotation center and When the rotating pin 5 is rotated with respect to the shaft 9 serving as the first rotation center beyond the dead point of the tension coil spring 8, the biasing direction is reversed.

  In particular, FIG. 1 shows the deck board B inverted from the normal use state by 180 ° from the normal use state while viewing the base plate 2 side obliquely from above in order to help understand the structure of the main part. It is a thing. Accordingly, in a normal use state, the deck board B is used at a position rotated 180 degrees to the left in the direction of the arrow around the rotation pin 5, so that the bracket 3, the rotation pin 5, and the bearing portion 12 are It does not appear on the lower surface of the board B.

  For the storage chamber 1 defined between the floor panel P and the deck board B, as shown in FIG. 4, the front and rear edges of the deck board B are placed on the front upper end and the rear upper end. The racks 13A and 13B to be placed are provided so that the deck board B moved to the upper position can be horizontally supported. In particular, for the rack 13B at the upper rear end away from the vertical movement mechanism, When the deck board B is supported horizontally in cooperation with the front upper shelf 13A, the rear edge of the deck board B can be placed on the shelf 13B, and the front edge of the deck board B is placed in the storage chamber 1. When entering and slanting, the size does not interfere with the rear edge of the deck board B.

  Therefore, when the deck board B is moved up and down with respect to the storage chamber 1 using the vertical movement mechanism having such a configuration, the deck board B is moved to an upper position covering the opening of the storage chamber 1. As shown in FIG. 5, the front and rear edges of the deck board B are horizontally supported by the corresponding shelves 13A and 13B. At this time, the biasing spring pressure of the tension coil spring 8 is The rotating pin 5 is biased only in the upper end direction of the circumferential groove 10 of the base plate 2.

  Then, when the deck board B is moved to the lower position from this state, as shown in FIG. 6, while holding the handle 14 provided on the rear end side of the deck board B and lifting it upward, the deck board B When a slight force is applied to B, the guide of the link arm 4 is obtained in conjunction with this, and the rotating pin 5 moves in the circumferential groove 10 of the base plate 2 against the biasing spring pressure of the tension coil spring 8. Since it slides in the lower end direction, the front end edge side of the deck board B comes off from the corresponding shelf 13A.

  In this case, as described above, if the rotation pin 5 serving as the second rotation center is directly above the shaft 9 serving as the first rotation center, the link arm 4 cannot rotate, Although all the loads are received, since the movable side upper end 4a of the link arm 4 is set so as to avoid the position directly above the shaft 9, the link arm 4 rotates to move the deck board B in the lower position direction. The link arm 4 itself is not damaged. Further, when the link arm 4 is thin and cannot sufficiently support the inclination on the second rotation center side, this is supplemented by the circumferential groove 10 and the rotating pin 5 sliding in the circumferential groove 10, and both are combined. , Can firmly guide the movement of the deck board B.

  Next, when the rotation pin 5 exceeds the dead point of the tension coil spring 8, the urging direction of the tension coil spring 8 is reversed, and the rotation pin 5 is rotated by the urging spring pressure of the tension coil spring 8. Accordingly, the front end edge side of the deck board B enters the storage chamber 1 and tilts as shown in FIG.

  In this case, the interval Wp between the shelves 13A and 13B is smaller than the length WB of the deck board B, while the front edge of the deck board B is positioned at the lower corner of the storage chamber 1 so that the deck board B is inclined. Wp · WB · D (depth of the storage chamber) is set so as to be larger than the length WB ′ in the direction along the interval Wp of the deck board B at that time.

  Therefore, after that, when the grip on the handle 14 is released, the deck board B can stably move to the lower position along the floor panel P as shown in FIG. It is easier to move to the lower position, but in this case, if the working length is shorter than that of the conventional tonneau board and a part of the weight of the deck board B is supported. In any case, the work becomes easy anyway.

  On the contrary, when the deck board B is moved from the lower position to the upper position, the above-described work order is reversed. In particular, in this case, the rotating pin 5 exceeds the dead point of the tension coil spring 8. Then, the urging direction of the tension coil spring 8 is reversed, and this time, the rotating pin 5 is automatically guided to the upper end direction of the circumferential groove 10 by the urging spring pressure of the tension coil spring 8, so that it moves with a very light force. There are advantages that can be made.

  When the guide of the link arm 4 is obtained and the rotary pin 5 slides in the circumferential groove 10 of the base plate 2 in the upper end direction by the biasing spring pressure of the tension coil spring 8, the front end of the deck board B is thereafter obtained. When the edge side is placed on the corresponding shelf 13A and the grip 14 is released, the deck board B covers the opening of the storage chamber 1 by the action of the shelves 13A and 13B as shown in FIG. It can move to the upper position.

  Next, the deck board vertical movement mechanism according to the second embodiment will be described.The second embodiment basically follows the above first embodiment as it is, The difference is that, as shown in FIG. 9, a resin tray 15 separately formed in the storage chamber 1 is disposed, and the entire circumference of the storage chamber 1 has a double wall structure, so that the storage chamber 1 on the outside is provided. The base plate 2 is fixed to the side wall of the housing, and a space 16 is defined between the side wall of the outer storage chamber 1 and the side wall of the resin tray 15, and the link arm 4 is stored in the space 16. It becomes the composition which does. In this case, although not specifically shown, in order to guide the movement of the rotating pin 5, a groove shape that matches the circumferential groove 10 of the base plate 2 is also provided on the side wall of the resin tray 15. Needless to say.

  Therefore, under the second embodiment, the tension coil spring 8 and the base plate 2 are of course used. In particular, the link arm 4 is not exposed in the resin tray 15, so that the appearance is improved and the link is made with a load. There is no need to worry about the arm 4 being damaged. The other functions and effects are the same as those of the first embodiment, and the description thereof is omitted here.

  Since the vertical movement mechanism according to the present invention can easily move the deck board between the lower position along the floor panel and the upper position covering the opening of the storage room, this is provided at the rear of the automobile. If it is applied to a mechanism that moves the deck board arranged on the floor panel of the deck room up and down, it will be very convenient.
