JP 2002-87166 A

When assembling the slide deck device having the above structure to the vehicle, the lower rail is first fixed, the upper rail integrated with the lock mechanism is assembled to the fixed lower rail, and finally the slide board integrated with the operation handle and the cable is connected to the cable. Fix the left and right upper rails while connecting the ends of the and the locking claws.
However, since the end portion of the cable and the lock claw are located on the lower surface side of the slide board, it is not easy to connect the end portion of the cable and the lock claw.
In addition, since the movement of the operation handle and the lock claw that are connected to each other via the cable is always linked (because there is no play), the operation handle can be moved only slightly by hitting the operation handle with the load or the body of the passenger, The lock may be released unexpectedly.

  An object of the present invention is to easily assemble a slide board integrated with an operation member for operating the lock mechanism and a cable for linking the operation member and the lock mechanism to the upper rail integrated with the lock mechanism, In addition, an object of the present invention is to provide a vehicular slide deck device capable of providing a predetermined play between the operation of the operation member and the operation of the lock mechanism.

A slide deck device for a vehicle according to the present invention includes a lower rail fixed to a floor surface of a luggage room of a vehicle having a back door, extending in the front-rear direction, an upper rail slidable along the lower rail, and the upper rail provided on the upper rail. A locking mechanism capable of transitioning between a locked state that can be fixed to the lower rail and an unlocked state that cannot be fixed; a slide board that is slidable along the lower rail together with the upper rail; and the slide board provided on the slide board, And an operating member for operating the locking mechanism, wherein the operating member is rotatably supported on the lower surface of the slide board and is separated from the locking mechanism in conjunction with the operation of the operating member. A lock allowable position for allowing the lock mechanism to enter the locked state, and the lock machine; And a lock switching member that moves to the unlocking position to shift to the unlocked state by contacting the lock, and the lock switching member is always separated from the lock mechanism when the lock switching member is located at the lock permissible position. .

  The slide board is preferably separable from the upper rail.

  The lock mechanism is rotatable with respect to the upper rail between a lock position that engages with a lock hole formed in the lower rail and an unlock position that escapes from the lock hole, and is engaged with the lock switching member. It is preferable to include a lock claw that integrally has a pressed part to be removed.

According to the present invention, when the lock switching member is located at the lock permissible position, it always leaves the lock mechanism, so that there is always a predetermined play between the operation of the operation member and the operation of the lock mechanism. Therefore, since the lock mechanism does not move only when the operation member is slightly moved by hitting the operation member with a load or a passenger's body, it is possible to effectively prevent the lock from being released unexpectedly.

Furthermore, when assembling the operation member and the slide board integrated with the lock switching member to the upper rail integrated with the lock mechanism, it is not necessary to connect the lock switching member and the lock mechanism, so the slide board can be easily attached to the upper rail. Can be assembled.

  According to the invention of claim 3, the structure of the lock mechanism is simplified and the number of parts can be reduced.

It is possible to rotate between the unlock position (the position of the phantom line in FIG. 11) to escape, and is urged to rotate toward the lock position by the urging force of a torsion coil spring (not shown). Further, the upper end portion of the lock claw 62 is a pressed portion 64 that protrudes above the horizontal support piece 51 through a notch 51 a formed in the horizontal support piece 51 on the vehicle exterior side.
As shown in FIGS. 2 and 5, etc., one pin member P1 is fixed (projected) on the upper surface of the horizontal support piece 51 of the left and right upper rails 50, and a circular shape is formed near the upper end of the pin member P1. The pressing member P1a is fixed. Further, a total of three through holes 51b are formed in the horizontal support pieces 51 of the left and right upper rails 50, and nuts (not shown) are respectively provided at positions corresponding to the through holes 51b on the lower surface of the horizontal support piece 51. It is welded.
Each component described above is a component of the rail unit 25. The rail unit 25 is previously unitized outside the vehicle 10, and the front bracket 26 and the rear bracket 27 are fixed to the bottom plate 15 in a united state. The Therefore, when the rail unit 25 is attached to the bottom plate 15, the left and right lower rails 30 become parallel, and the left and right lower rails 30, the front side connecting member 41 and the rear side connecting member 43 constitute a cross beam structure. Even if an external force is applied, the left and right lower rails 30 maintain a parallel state. Therefore, the left and right upper rails 50 can always slide smoothly with respect to the left and right lower rails 30.

Next, the structure of the board unit 70 will be described.
The slide board 71, which is a main member of the board unit 70, is a plate material having a rectangular shape in plan view, and its left and right width is slightly longer than the interval between the left and right lower rails 30, and its front and rear length is substantially the same as that of the lower rail 30.
A pair of left and right gripping concave portions (gripping portion, first gripping portion) 72 and a gripping concave portion (gripping portion, second gripping portion) 73 are provided in the vicinity of the rear end portion of the upper surface of the slide board 71. is there. The left and right gripping recesses 72 and 73 are both rectangular in shape, and the gripping recess 72 and the gripping recess 73 extend in the front-rear direction through the center line of the slide board 71 (through the center of the slide board 71). (Straight line). Further, an operation recess 75 located between the grip recess 72 and the grip recess 73 is provided in the rear edge portion of the upper surface of the slide board 71. As shown in the figure, the distance from the operation recess 75 to the gripping recess 72 is shorter than the distance from the operation recess 75 to the gripping recess 73. A through-hole (not shown) that communicates between the operation recess 75 and the lower space of the slide board 71 is formed in the front surface of the operation recess 75. A pair of left and right mounting recesses 76 and a mounting recess 77 are provided on the upper surface of the slide board 71. The left and right mounting recesses 76 and 77 are both rectangular in shape, and the mounting recess 76 and the mounting recess 77 are symmetrical with respect to the center line.
An upper end of the rotation support shaft 79 extending in the vertical direction is rotatably provided at a portion of the lower surface of the slide board 71 located immediately before the operation recess 75, and the above-mentioned through-hole is provided in the vicinity of the upper end portion of the rotation support shaft 79. An operation member 80 positioned in the operation recess 75 through the hole is fixed. The operation member 80 is rotatable between an initial position indicated by a solid line in FIG. 4 and an unlocking operation position indicated by an imaginary line, and a rotation of a coil spring (not shown) provided around the rotation support shaft 79 is provided. It is urged to rotate toward the initial position by the force. A rotary pulley 82 composed of a two-layer pulley is fixed to a portion of the rotation support shaft 79 located below the operation member 80, and one end of each of the two operation wires W is fixed to the peripheral surface of the rotation pulley 82. It is. The portions of the two operation wires W other than both ends are covered with a covering tube T made of a flexible material, and the other ends of the operation wires W are located immediately below the mounting recess 76 and the mounting recess 77. ing. An upper end of a rotation support shaft 83 extending downward is fixed to a portion of the lower surface of the slide board 71 located immediately below the mounting recess 76 and the mounting recess 77, and the left and right rotation support shafts 83 are flat. An approximately J-shaped lock switching member 84 is rotatably supported. One end of the lock switching member 84 is a connection piece 85 to which the end of the operation wire W is connected, and the other end of the lock switching member 84 is a pressing piece 86 parallel to the connection piece 85. Since both ends of the tension spring S are engaged with the lower surface of the lock switching member 84 and the slide board 71, the left lock switching member 84 is urged to rotate clockwise in FIG. 84 is urged to rotate counterclockwise in FIG. Since the left and right lock switching members 84 are linked to the operation member 80 via the operation wire W, the rotary pulley 82, and the rotation support shaft 79, the rotation operation of the operation member 80 and the rotation operation of the lock switching member 84 are linked. Therefore, when the operation member 80 is located at the initial position, the lock switching member 84 is located at the lock permissible position (the position where the connecting piece 85 and the pressing piece 86 face substantially in the front-rear direction) indicated by the broken line in FIG. Is positioned at the unlocking position indicated by the two-dot chain line in FIG.
On the bottom surfaces of the mounting recess 76 and the mounting recess 77, four through-holes communicating the mounting recesses 76, 77 and the lower space of the slide board 71 are formed. One is a harpoon hole 90 having a large-diameter circular hole 88 and a narrow portion 89 extending rearward from the rear end of the large-diameter circular hole 88 and narrower than the large-diameter circular hole 88. The rest are through holes 91, 92, 93 that are both circular.
The mounting recess 76 and the mounting recess 77 have the same planar shape as the mounting recesses 76, 77 and can be detachably closed by a cover plate 95 made of the same material as the slide board 71.
Each component described above is a component of the board unit 70, and the board unit 70 is previously unitized outside the vehicle 10.

Next, a procedure for assembling the board unit 70 to the rail unit 25 fixed to the bottom plate 15 will be described.
Prior to assembly, the left and right upper rails 50 are first positioned at positions corresponding to any of the members to be locked 36, 37, and 38, and the engaging protrusions 61 of the lock claws 62 are engaged with the through holes 60 and the lock holes 39. Leave it locked. Then, the large-diameter circular holes 88 of the left and right daruma holes 90 are positioned immediately above the pin members P1 (pressing members P1a) of the left and right upper rails 50, and the front end of the slide board 71 is slightly inclined downward with respect to the rear end. The entire slide board 71 is moved downward. Then, the left and right holding members P1a (and the pin member P1) having a diameter smaller than that of the large-diameter circular hole 88 project through the large-diameter circular hole 88 into the mounting recess 76 and the mounting recess 77, and thus the slide board 71. The slide board 71 is moved forward with respect to the upper rail 50 while maintaining the above inclination. Then, the left and right pin members P1 enter the narrow width portions 89 of the left and right daruma holes 90, and the left and right pressing members P1a are positioned immediately above the left and right narrow width portions 89 and have a diameter larger than the width of the narrow width portions 89. A part of the holding member P <b> 1 a having a large contact with the upper surface of the slide board 71. At this time, the three through holes 51b projecting from the left and right upper rails 50 are positioned directly below the left and right through holes 91, 92, 93, respectively. When the rear end of the slide board 71 is lowered to the same position as the front end and the lower surface of the slide board 71 is brought into contact with the upper surface of the horizontal support piece 51 of the left and right upper rails 50, the entire lower surface of the pressing member P1a contacts the upper surface of the slide board 71. In addition, since the three through-holes 51b of the upper rail 50 and the three through-holes 91, 92, 93 of the slide board 71 communicate with each other, three bolts (not shown) are omitted in the mounting recesses 76, 77. Are inserted into the through holes 51b and the through holes 91, 92, 93, and screwed into the nuts located immediately below the through holes 91, 92, 93. When the slide board 71 is fixed to the left and right upper rails 50 in this way, as shown by the solid lines in FIG. 11, the pressing pieces 86 of the left and right lock switching members 84 (located at the lock allowable position) are positioned at the lock position. ) Located on the outer side of the pressed portion 64 of the lock claw 62, a gap is formed between the pressed portion 64 and the pressed portion. Further, the two support rollers 49 of the rail unit 25 come into contact with the lower surface of the slide board 71, respectively.
Finally, if the board unit 70 is completed by fitting the cover plate 95 into the mounting recess 76 and the mounting recess 77, the assembly operation of the board unit 70 and the rail unit 25 is completed.
As described above, the board unit is provided in the rail unit 25 having the lock mechanism including the lock claw 62, the torsion coil spring, the support piece 59 (lock claw support member 58), and the lock hole 39 (locked members 36, 37, 38). When assembling 70, it is not necessary to connect the lock claw 62 and the lock switching member 84 (or the operation wire W), so that the board unit 70 can be easily assembled to the rail unit 25.

Next, the operation of the slide deck device 20 configured as described above will be described.
When the back door 12 of the vehicle 10 closes the rear opening 11, the left and right upper rails 50 are located at positions corresponding to the left and right locked members 36, and the engagement protrusions 61 of the left and right lock claws 62 are located. The slide board 71 is positioned at the storage position in which the front end surface of the slide board 71 is located immediately after the second row seat 13 because it engages (locks) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the locked member 36. .
When the back door 12 is opened, the operator (passenger, driver) can hang the right hand on the gripping recess 72 and the left hand on the gripping recess 73. However, since the distance L1 in the left-right direction from the front end (rear end) of the operation member 80 located at the initial position to the left side surface of the gripping recess 72 is 100 mm or more, the right thumb is placed before the right thumb is put on the operation member 80. If the finger other than is placed on the gripping recess 72, the operation member 80 cannot be operated with the thumb of the right hand (further, the tip of the operation member 80 positioned at the initial position from the right end surface of the gripping recess 73 (rear) Since the distance L2 in the left-right direction to the end) is 150 mm or more, the operation member 80 cannot be operated even with the left thumb with a finger other than the thumb placed on the gripping recess 73). Therefore, when the right hand is put on the gripping recess 72, first, the right hand is brought close to the operation member 80 from the left side of the operation recess 75, and the right hand is moved to the right while the right thumb is put on the operation member 80. Rotate 80 to the unlocking operation position. Since the left-right direction distance L3 from the front end (rear end) of the operating member 80 moved to the unlocking operation position to the left side surface of the gripping recess 72 is 60 mm or less, the right hand can be obtained by rotating the operating member 80 to the unlocking operation position. The remaining finger of the right hand can be hung on the holding recess 72 while the operation member 80 is held in the unlocking operation position with the thumb of the user.
When the operation member 80 positioned at the initial position is rotated to the unlocking operation position side in this way, the rotation pulley 82 rotates and the operation wire W is pulled, so the left and right lock switching members positioned at the lock allowable position. 84 rotates to the unlocked position side. Then, when the lock switching member 84 is rotated by a predetermined distance to the lock release position side, the pressing piece 86 of the lock switching member 84 that has been separated from the lock claw 62 (the pressed portion 64) until then becomes the pressed portion 64. Contact. When the lock switching member 84 is rotated to the unlock position by rotating the operation member 80 to the unlock operation position, the left and right lock claws 62 are rotated to the unlock position. The portion 61 escapes outward from the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member to be locked 36, and the lock by the lock claw 62 is released (see the phantom line in FIG. 11).

  If the slide board 71 is pulled backward while the operation member 80 is held in the unlocking operation position, the roller 55, the roller 56, and the support roller 49 rotate, so the upper rail 50 and the board unit 70 are moved rearward with respect to the lower rail 30. Can be slid. When the left and right lock claws 62 are positioned on the sides of the member 37 to be locked, when the operation member 80 is released and the operation member 80 is rotated and returned to the initial position, the lock switching member 84 is rotated and returned to the lock allowable position. Therefore, the left and right lock claws 62 are rotated and returned to the lock position, and the engagement protrusion 61 is engaged (locked) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member 37 to be locked. Can be held at an intermediate position (not shown). Further, when the left and right lock claws 62 are positioned on the side of the member 38 to be locked, if the hand is released from the operation member 80 and the operation member 80 is rotated and returned to the initial position, the engagement protrusion 61 of the lock claw 62 is obtained. Engages (locks) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member to be locked 38, so that the slide board 71 can be held at the maximum drawing position (not shown).

  In the slide deck device 20 of the present embodiment described above, the lock switching member 84 (pressing piece 86) is separated from the lock claw 62 (pressed portion 64) when positioned at the lock allowable position. There is a predetermined play between the movement and the movement of the lock claw 62. Therefore, since the lock claw 62 does not move only when the operation member 80 is slightly moved due to a load or the body of a passenger hitting the operation member 80, the possibility that the lock by the lock claw 62 is unexpectedly released is small.

  Further, when the operation member 80 is rotated to the unlocking operation position when the rear portion of the vehicle 10 is parked on a slope with the rear portion being positioned below the front portion, the slide board 71 is caused to change its own load or the slide board 71. The load of the load placed on the upper surface may unexpectedly try to slide backward. However, in such a case, the operator tries to keep gripping the concave recesses 72 and 73 with the left and right hands in a reflective manner, but the right hand is open in the left and right direction (the left and right of the thumb and little finger). Because the direction interval is considerably wide), it is easy to reflect the thumb away from the operation member 80 in a reflective manner. In addition, when the operator removes the thumb from the operation member 80, the operation member 80 rotates to the initial position, which is a position away from the holding recess 72 as compared to the unlocking operation position. There is almost no possibility of operating the operating member 80 in a reflective manner. Therefore, in such a situation, the lock claw 62 located at the unlock position rotates to the lock position. Therefore, when the lock claw 62 is located at a position corresponding to the member 37 to be locked, the engagement claw of the lock claw 62 The portion 61 automatically engages (locks) with the through hole 60 of the lock claw support member 58 and the lock hole 39 of the member 37 to be locked. Therefore, in the slide deck device 20 according to the present embodiment, the possibility that the board unit 70 slides at a stretch from the intermediate position to the maximum drawing position is extremely small.

If the rail unit 25 is assembled in advance so that the support roller 49 (and the support bracket 47) are in a predetermined position and direction with respect to the rear connection member 43, the support roller 49 is attached by attaching the rail unit 25 to the bottom plate 15. Is in a predetermined position and a predetermined direction with respect to the bottom plate 15. As described above, when the slide deck device 20 is attached to the bottom plate 15, it is not necessary to adjust the position and direction of the support roller 49 with respect to the bottom plate 15, so that the slide deck device 20 can be easily attached to the bottom plate 15. In addition, the two support rollers 49 can surely prevent the bending of both sides of the center portion of the slide board 71, and the slide board 71 can be smoothly slid by the support roller 49.
Moreover, since the load support portion 44 provided on the lower surface of the rear connection member 43 that supports the support roller 49 is in contact with the bottom plate 15, the rear connection can be achieved even when a heavy load is placed on the slide board 71. The central portion of the member 43 is not greatly bent. Therefore, even when a heavy load is placed on the slide board 71, the lower surface of the slide board 71 can be stably supported by the support roller 49.
Further, since it is not necessary to fix the load support portion 44 to the bottom plate 15 with screws or the like, the work of attaching the rail unit 25 to the bottom plate 15 is not complicated.

Moreover, since the rear bracket 27, which is a member for fixing the left and right lower rails 30 to the bottom plate 15, is used as a member for fixing the rear connection member 43 to the lower rail 30, the rear connection member 43 is used. The number of parts can be reduced compared to the case of separately providing the bracket.
Furthermore, when both ends of the rear side connecting member 43 are fixed to the lower rail 30 or a bracket fixed to the lower rail 30 (not contacting the bottom plate 15), this load is applied when a heavy load is placed on the slide board 71. Therefore, the left and right lower rails 30 are deformed, and as a result, the sliding operation of the upper rails 50 may become unsmooth. However, since both ends of the rear connection member 43 are fixed to the rear bracket 27 that contacts the bottom plate 15, the load applied to the slide board 71 is supported by the support roller 49, the rotating shaft 48, the support bracket 47, and the rear connection. It is transmitted to the bottom plate 15 via the member 43 and the rear bracket 27 and is not transmitted to the lower rail 30. Therefore, even when a heavy load is placed on the slide board 71, the sliding operation of the upper rail 50 does not become unsmooth.

  Further, since the gap between the cover member 34 provided on the lower rail 30 and the upper rail 50 is narrow (see FIGS. 5, 6, and 9), the upper surface of the lower rail 30 is raised by pulling the slide board 71 backward. Even if a passenger drops a small object in a state where it is exposed, the possibility that the object will enter the lower rail 30 through the gap between the cover member 34 and the upper rail 50 is very small. Moreover, even if the object enters the lower rail 30 through the gap between the cover member 34 and the upper rail 50, the roller 55 presses the object forward when the slide board 71 is slid to the storage position (front end position). When the slide board 71 reaches the storage position, the object is lifted obliquely upward by the tapered surface of the head of the front end stopper member B3 and is discharged from the front end opening of the lower rail 30 to the front of the lower rail 30. The passenger can easily take the object out of the lower rail 30.

In the present embodiment described above, the operation member 80 and the lock switching member 84 are linked by the operation wire W, but may be linked by linkage means (for example, a link mechanism) having another structure. Further, the operation member and the lock switching member 84 may be linked directly.
Further, a lock mechanism having a structure different from that of the lock claw 62 or an operation member having a structure different from that of the operation member 80 may be employed.
