  However, according to the above-mentioned guide lever, the hinge portion is located in the guide groove and is always exposed to the luggage compartment side, so that it does not look good. Further, when the guide lever is always exposed to the cargo compartment side, the cargo placed in the cargo compartment is likely to interfere with the guide lever. In order to avoid such interference, when moving the deck board, it is necessary to take the luggage out of the cargo room once, and the work of moving the deck board becomes troublesome.

  The present invention has been completed based on the above circumstances, and an object thereof is to facilitate the work of moving the deck board and improve the appearance of the cargo compartment.

  The present invention is a deck board moving mechanism installed in a cargo compartment of a vehicle, and is capable of moving between an upper position where the cargo compartment is divided into upper and lower stages and a lower position below the upper position. And a guide shaft projecting from both sides in the vehicle width direction on the vehicle front side of the deck board, and an upper stage fixed position corresponding to the upper position and a lower stage corresponding to the lower position provided on the side walls constituting both sides of the cargo space in the vehicle width direction. A guide groove that guides the guide shaft between the fixed position, a restriction position that appears in the guide groove to restrict the guide shaft from reversing, and a permissible position that is hidden inside the side wall and allows the guide shaft to move in the normal direction. And a valve member that can be moved in and out.

  According to such a configuration, the deck board can be moved to the upper position by guiding the guide shaft to the upper stage fixed position by the guide groove, and the deck can be moved by the guide shaft being guided to the lower stage fixed position by the guide groove. The board can be moved to a lower position. At this time, if the guide shaft moves in the normal direction, the valve member is hidden inside the side wall and allows the guide shaft to move. However, if the guide shaft attempts to reverse, the valve member appears in the guide groove and reverses the guide shaft. To regulate. That is, since the valve member is hidden inside the side wall when the guide shaft moves, the valve member and the load placed in the cargo compartment do not interfere with each other. Therefore, the deck board can be moved while the luggage is placed in the luggage compartment, and the moving operation can be facilitated. Moreover, since the valve member is not exposed to the cargo compartment side during the movement of the deck board, the appearance of the cargo compartment can be improved.

The following configuration is preferable as an embodiment of the present invention.
The valve member may be rotatably supported by a hinge portion, and the hinge portion may be arranged inside the side wall.
According to such a configuration, since the hinge portion is not exposed to the luggage compartment, the appearance of the luggage compartment can be improved.

The guide groove includes a horizontal groove that connects the intermediate position set in the middle from the lower fixed position to the upper fixed position and the upper fixed position in the horizontal direction. It is good also as a structure which comprises the boarding surface which comprises a part, and the boarding surface has comprised the surface by the side of the middle position among the lower surfaces of a horizontal groove.
According to such a configuration, when the guide shaft goes from the midway position through the horizontal groove to the upper fixed position, the valve member restricts the backward movement of the guide shaft at the restricting position. Further, the guide shaft can be smoothly transferred from the lower surface of the horizontal groove to the riding surface.

The guide groove has an inclined groove that connects an arbitrary position from the middle position to the upper stage fixed position and the lower stage fixed position in an oblique direction, and the valve member is pushed into the allowable position by contacting the guide shaft that moves the inclined groove. It is good also as a structure provided with the pushing surface which can be.
According to such a configuration, when the guide shaft moves from the lower fixed position through the inclined groove to the middle position, the guide shaft that moves through the inclined groove contacts the pushing surface to push the valve member into the allowable position. it can.

An upper and lower groove into which the guide shaft can be dropped is formed between the lower surface of the horizontal groove between the surface on the upper fixed position side and the riding surface at the restricting position. It is good also as a structure which guides a guide shaft from an intermediate position to an upper stage fixed position by moving with the guide shaft which got on, and closing an up-and-down groove | channel.
According to such a configuration, when the guide shaft goes from the upper fixed position through the horizontal groove to the lower fixed position, the guide shaft can be dropped by its own weight in the upper and lower grooves. Also, when the guide shaft goes from the middle position through the horizontal groove to the upper fixed position, the valve member moves together with the guide shaft that rides on the riding surface to close the upper and lower grooves, so that the guide shaft falls in the upper and lower grooves. It is possible to guide the guide shaft from the riding surface to the upper fixed position while preventing this.

The riding surface at the restriction position is connected with a step on the surface on the upper fixed position side of the lower surface of the horizontal groove with the pushing surface as a boundary surface, and the step is configured to have a high shape on the riding surface side. Good.
According to such a configuration, the valve member can be moved from the restricting position to the permissible position by the guide shaft contacting the pushing surface with a step.

<Embodiment 1>
Embodiment 1 of the present invention will be described with reference to the drawings of FIGS. FIG. 1 and FIG. 2 are perspective views of a vehicle 1 having a rear door (not shown) such as a minivan or a station wagon as viewed obliquely from the rear. A luggage compartment 3 is formed behind the rear seat 2 of the vehicle 1. Further, a rear opening 4 is formed by opening the rear door at the vehicle rear side of the cargo compartment 3, and the cargo is carried into the cargo compartment 3 through the rear opening 4.

  The cargo compartment 3 can be divided into two upper and lower stages by a deck board 7 arranged at an upper position shown in FIG. At this time, the upper surface of the deck board 7 is set to be substantially the same height as the lower end portion of the rear opening 4, so that the luggage placed on the upper surface of the deck board 7 can be easily taken out. On the other hand, when it is desired to load a large load, a large luggage space can be obtained in the luggage compartment 3 by arranging the deck board 7 at the lower position shown in FIG. In the following description, the lower side in a state where the cargo compartment 3 is divided into two upper and lower stages is referred to as an accommodation space 3A.

  The rear seat 2 is a split-foldable seat, and includes a seat back 2A for receiving the back and waist of a seated person (not shown), a headrest 2B for receiving the head of the seated person, and the like. Further, the rear seat 2 is provided with a reclining device (not shown) for freely adjusting the inclination of the seat back 2A. When a large amount of luggage is loaded, the seat back 2A is tilted forward of the vehicle to load the cargo compartment 3 The luggage space can be expanded. At this time, the upper surface of the deck board 7 is set to be substantially flush with the rear surface of the seat back 2A that has fallen forward in the vehicle.

  As shown in FIGS. 1 and 2, the accommodating space 3A includes a floor 3B that constitutes the lower surface side, a front wall 3C that constitutes the vehicle front side, both side walls 3D that constitute both sides in the vehicle width direction, and the like. As shown in FIG. 3, a guide groove 5 having a groove shape is provided on the vehicle front side of the side wall 3D. One guide groove 5 is provided on each side wall 3D and is arranged to be symmetrical to each other. The floor 3B is a flat surface and is formed as a part of the body or is formed of a plate material made of a synthetic resin material or a wood-based material.

  As shown in FIG. 4, the deck board 7 has a single plate shape, and an operation portion 72 used for opening / closing and moving the deck board 7 is provided at the rear end portion of the upper surface. A pair of guide shafts 71 project outwardly at both ends in the vehicle width direction on the vehicle front side of the deck board 7. Both guide shafts 71 are arranged coaxially and can be accommodated inside the both guide grooves 5. The guide groove 5 has a guide shaft between an upper fixed position 51 (position of the guide shaft 71 in FIG. 5) corresponding to the upper position and a lower fixed position 52 (position of the guide shaft 71 in FIG. 7) corresponding to the lower position. 71 can be guided. The detailed structure of the guide groove 5 will be described later.

  As shown in FIG. 5, the deck board 7 at the upper position is disposed above the floor 3 </ b> B of the accommodation space 3 </ b> A by a predetermined height and is held in a horizontal posture. A rear support portion 6 that supports the rear end portion of the deck board 7 at the upper position is formed on the rear wall 3E so as to protrude forward. Therefore, the deck board 7 located at the upper position is supported at the front and rear two locations by the guide groove 5 and the rear support portion 6. When the guide shaft 71 is moved to the lower fixed position while the deck board 7 is tilted as shown in FIG. 6, the deck board 7 at the lower position is supported on the entire surface by the floor 3B as shown in FIG.

  Next, the detailed structure of the guide groove 5 will be described with reference to FIGS. As shown in FIG. 8, the guide groove 5 includes a horizontal groove 5 </ b> A formed in the horizontal direction, an inclined groove 5 </ b> B formed in an oblique direction (a direction going upward when going toward the rear of the vehicle), and the like. . The horizontal groove 5A connects the upper fixed position 51 and a midway position 53 set on the vehicle rear side of the upper fixed position 51 in the horizontal direction. Further, the inclined groove 5B connects the lower fixing position 52 and the vicinity of the middle of the horizontal groove 5A in an oblique direction.

  In the inclined groove 5B, a connecting portion 5C having an opening that becomes wider as it approaches the horizontal groove 5A is formed in the connecting portion of the horizontal groove 5A. The vehicle front side of the connecting portion 5 </ b> C is configured by a vertical surface 54 that stands up and down. On the other hand, the vehicle rear side of the connecting portion 5C is formed in an oblique direction continuously with the inclined surface 55 constituting the vehicle rear side of the inclined groove 5B. A part of the substantially square valve member 10 appears from the inclined surface 55 in the connecting portion 5C.

  The valve member 10 is rotatably supported on the side wall 3D by the hinge portion 11. The hinge portion 11 pivotally supports the vicinity of the lower portion of the front end of the valve member 10, and is fixed inside the side wall 3 </ b> D on the vehicle rear side with respect to the inclined surface 55. For this reason, since the hinge part 11 is hidden inside the side wall 3D and is not exposed to the inclined groove 5B, the appearance of the luggage compartment 3 can be improved. Further, the valve member 10 is urged by an urging member (not shown) so as to be always located at the restriction position (the position of the valve member 10 in FIG. 8). The restricting position refers to a position where the valve member 10 appears from the inclined surface 55 to the connecting portion 5 </ b> C and restricts the backward movement of the guide shaft 71.

  The valve member 10 includes a pushing surface 12 that extends in the up-down direction at the restriction position. The pushing surface 12 moves the valve member 10 to the allowable position (the position of the valve member 10 in FIG. 11) by coming into contact with the guide shaft 71 moving obliquely rearward from the lower fixed position 52 through the inclined groove 5B. The allowable position refers to a position where the valve member 10 is hidden inside the side wall 3D constituting the inclined surface 55 and allows the guide shaft 71 to move in the normal direction. That is, the valve member 10 is provided so as to be able to appear and retract with respect to the inclined surface 55 by moving between the restriction position and the allowable position.

  In the restricting position, as shown in FIG. 8, an upper and lower groove 5 </ b> D extending in the vertical direction is formed between the vertical surface 54 of the connecting portion 5 </ b> C and the pushing surface 12 of the valve member 10. The upper and lower grooves 5 </ b> D have a width that is larger than the diameter of the guide shaft 71. Therefore, as shown in FIG. 9, when the guide shaft 71 reaches the upper entrance portion of the upper and lower grooves 5D from the upper fixed position 51 through the horizontal groove 5A, the guide shaft 71 falls by the own weight and passes through the inclined grooves 5B. To the lower fixed position 52.

  The valve member 10 includes a riding surface 13 that is connected in a flush manner with the surface on the midway position 53 side of the lower surface of the horizontal groove 5A when in the restricted position. Thereby, the guide shaft 71 is smoothly guided from the midway position 53 to the riding surface 13 through the horizontal groove 5A.

  As shown in FIG. 12, the valve member 10 is rotatable to a forward tilt position (position of the valve member 10 in FIG. 12) that is tilted forward of the vehicle from the restriction position. On the vehicle front side of the riding surface 13, a riding protrusion 14 that protrudes upward is formed. Therefore, when the guide shaft 71 riding on the riding surface 13 moves to the front side of the vehicle, the guide shaft 71 comes into contact with the riding protrusion 14, whereby the valve member 10 rotates together with the guide shaft 71 to the front side of the vehicle. It reaches the forward tilt position.

  In the forward tilt position, as shown in FIG. 12, the climbing protrusion 14 is connected so as to be substantially flush with the surface on the upper fixed position 51 side of the lower surface of the horizontal groove 5A. As a result, the upper and lower grooves 5D are closed, and the guide shaft 71 is smoothly guided from the riding surface 13 to the upper fixed position 51 through the riding protrusion 14 and the horizontal groove 5A. The upper stage fixed position 51 is formed one step lower so that the guide shaft 71 is fitted therein, so that the guide shaft 71 is not inadvertently removed from the upper stage fixed position 51.

Next, the operation of the guide shaft 71 accompanying the movement of the deck board 7 will be described.
First, when the deck board 7 is at the upper position shown in FIG. 5, the guide shaft 71 is located at the upper fixed position 51 as shown in FIG. From this point, when the operation portion 72 of the deck board 7 is lifted upward and pulled backward, the guide shaft 71 reaches the upper end inlet portion of the upper and lower grooves 5D through the horizontal groove 5A as shown in FIG. Thereafter, the guide shaft 71 falls downward through the upper and lower grooves 5D, and reaches the lower fixed position 52 through the inclined groove 5B as shown in FIG. Then, when the operation unit 72 is released, the deck board 7 is supported on the entire surface of the floor 3B and reaches the lower position as shown in FIG.

  Next, when the operation portion 72 of the deck board 7 is lifted and pulled backward, the guide shaft 71 moves obliquely rearward along the inclined surface 55 of the inclined groove 5B as shown in FIG. When the guide shaft 71 comes into contact with the pushing surface 12 of the valve member 10, the valve member 10 receives the pressing force from the guide shaft 71 and rotates to the vehicle rear side, as shown in FIG. 11, inside the side wall 3D. It reaches a permissible position in a completely hidden state. The guide shaft 71 is allowed to move obliquely rearward along the inclined surface 55 and the pushing surface 12, and reaches the midway position 53 through the horizontal groove 5A. At the same time, the valve member 10 is returned to the restricted position by a biasing member (not shown).

  From here, when the operation part 72 of the deck board 7 is pushed to the front side of the vehicle, the guide shaft 71 smoothly transitions to the riding surface 13 through the horizontal groove 5 </ b> A and contacts the riding protrusion 14. The valve member 10 rotates together with the guide shaft 71 toward the front side of the vehicle and reaches a forward tilt position. Then, the upper and lower grooves 5D are closed and the riding protrusion 14 and the lower surface of the horizontal groove 5A are connected, and the guide shaft 71 passes through the riding protrusion 14 and the horizontal groove 5A to the upper fixed position 51. And so on. At the same time, the valve member 10 is returned to the restricted position by a biasing member (not shown). Then, when the operation unit 72 is released, the deck board 7 is supported at two positions in the front and rear by the upper fixing position 51 of the guide groove 5 and the rear support unit 6 as shown in FIG. It reaches.

  As described above, in the present embodiment, when the guide shaft 71 contacts the pushing surface 12, the valve member 10 is rotated to the allowable position, and the valve member 10 is completely hidden from the inclined surface 55 inside the side wall 3D. Can be. Therefore, the appearance of the luggage compartment 3 can be improved. Further, since the valve member 10 does not interfere with the luggage in the luggage compartment 3, the deck board 7 can be moved while the luggage is placed in the luggage compartment 3.

  Since the lower surface of the horizontal groove 5 </ b> A and the riding surface 13 are flush with each other at the restriction position, the guide shaft 71 can be smoothly transferred from the midway position 53 to the riding surface 13. Further, since the guide shaft 71 riding on the riding surface 13 comes into contact with the riding protrusion 14 and rotates the valve member 10 to the forward tilted position so as to close the upper and lower grooves 5D, it is dropped by the upper and lower grooves 5D. The guide shaft 71 can be moved from the riding surface 13 to the upper fixed position 51.

  As shown in FIG. 13, the guide groove 25 of the present embodiment includes a horizontal groove 25 </ b> A formed in the horizontal direction and an inclined groove 25 </ b> B formed in the oblique direction, as in the first embodiment. . Unlike the connection portion 5C of the first embodiment, the connection portion of the inclined groove 25B with the horizontal groove 25A is formed with substantially the same width as the inclined groove 25B. Further, the pushing surface 22 of the valve member 20 is in contact with a front inclined surface 56 constituting the vehicle front side of the inclined groove 25B. Above the front inclined surface 56, the pushing surface 22 is disposed facing the upper fixed position 51 side. In other words, the riding surface 23 at the restriction position is connected to the surface on the upper fixed position 51 side in the lower surface of the horizontal groove 25A with the pushing surface 22 as a boundary surface, and the step is shaped to be higher on the riding surface 23 side. It is said that. In addition, the riding surface 23 of this embodiment is not provided with the riding protrusion 14 of Embodiment 1, but is formed flat.

Next, the operation of the guide shaft 71 accompanying the movement of the deck board 7 will be described.
First, the guide shaft 71 is located at the upper fixed position 51 when the deck board 7 is in the upper position. From here, when the operation part 72 of the deck board 7 is lifted upward and pulled backward, the guide shaft 71 hits the pushing surface 22 through the horizontal groove 25A as shown in FIG. From here, as shown in FIG. 14, when the valve member 20 is rotated to the vehicle rear side against the urging force of the urging member (not shown), the guide shaft 71 falls into the inclined groove 25B and is inclined. It reaches the lower fixed position 52 through the groove 25B. When the operation unit 72 is released, the deck board 7 is supported by the entire surface of the floor 3B and reaches the lower position.

  Next, when the operation unit 72 of the deck board 7 is lifted and pulled rearward, the guide shaft 71 moves obliquely rearward along the inclined groove 25B. Then, as shown in FIG. 15, when the guide shaft 71 comes into contact with the pushing surface 22 of the valve member 20, the valve member 20 receives the pressing force from the guide shaft 71 and rotates to the rear side of the vehicle. As shown, it is completely hidden inside the side wall 3D and reaches the allowable position. In the allowable position, the guide shaft 71 is allowed to move obliquely rearward along the inclined groove 25B, and reaches the intermediate position 53 through the horizontal groove 25A. At the same time, the valve member 20 is returned to the restricted position by the biasing member.

  From this point, when the operation portion 72 of the deck board 7 is pushed to the vehicle front side, the guide shaft 71 smoothly transitions to the riding surface 23 through the horizontal groove 25A, passes through the step and reaches the upper stage fixed position 51. . Then, when the operation unit 72 is released, the deck board 7 is supported at the front fixed position 51 and the rear support unit 6 at the front and rear two positions and reaches the upper position.

  As described above, in the present embodiment, since the horizontal groove 25A and the inclined groove 25B are completely partitioned by the valve member 20 in the restricting position, the guide shaft 71 moves backward between the horizontal groove 25A and the inclined groove 25B. This can be surely prevented. Further, when moving from the upper position to the lower position, the pushing surface 22 can be pushed in by the guide shaft 71 against the urging force of the urging member, so that the deck board 7 is reliably moved with a moderate feeling of moderation. be able to.
