Description

  The present invention relates to a slide deck device provided on a luggage room floor surface of a vehicle including a back door.

As a prior art of the slide deck apparatus in a vehicle, there exists what was disclosed by patent document 1, for example.
The slide deck device of Patent Document 1 is slidable in the front-rear direction along a pair of left and right guide rails 6 extending in the front-rear direction fixed to the bottom of a luggage room 2 formed at the rear part of the vehicle body 1 and the left and right guide rails 6. A luggage floor 4 having a pair of left and right movable rollers 7 and a pair of left and right fixed rollers 8 provided on a pair of left and right guide rails 6 for rotatably supporting the bottom surface of the luggage floor 4 are provided.
The guide rail 6 is provided with a lock hole 11g, and a lock means 11 having a lock pin 11e that can be engaged with and disengaged from the lock hole 11g is provided on the lower surface of the luggage floor 4.
Further, the pull handle 9 provided on the luggage floor 4 is provided with a lock release lever 20 slidable with respect to the pull handle 9. The unlocking lever 20 is slidable between a lock operation position and an unlock operation position, and is urged to the lock operation position by an urging means. The lock release lever 20 is linked to the lock pin 11e. When the lock release lever 20 is located at the lock operation position, the lock pin 11e is located at a lock position engageable with the lock hole 11g, and the lock release lever 20 is unlocked. When located at the lock operation position, the lock pin 11e is located at the unlock position where it cannot be engaged with the lock hole 11g.

In this slide deck device, when the luggage floor 4 is located at the storage position where it is completely stored in the luggage room 2, the lock pin 11e is inserted into the lock hole 11g unless the driver or passenger operates the lock release lever 20. By engaging (locking), the luggage floor 4 is held in the storage position.
When the driver or passenger slides the unlocking lever 20 to the unlocking operation position, the lock pin 11e is moved to the unlocking position to escape from the lock hole 11g, so that the luggage floor 4 can be pulled out from the gauge room 2 backward. It becomes like this. When the lock release lever 20 is returned to the lock operation position when the luggage floor 4 reaches the rearmost maximum drawing position, the lock pin 11e is engaged with the lock hole, and the luggage floor 4 is held at the maximum drawing position. .
JP 2003-341431 A

In the slide deck device of Patent Document 1, if the lock pin 11e does not engage with the lock hole when the luggage floor 4 slides to the maximum drawing position, the left and right movable rollers 7 provided on the luggage floor 4 are connected to the left and right guide rails. 6, the luggage floor 4 is prevented from coming out from the vehicle body backward.
However, if the luggage floor 4 slides vigorously backward when the lock is released, for example, on a slope, the movable roller 7 and the fixed roller 8 are contacted violently, causing the movable roller 7 and the fixed roller 8 to be damaged. There is a possibility that the sliding operation of 4 becomes unsmooth.

In order to solve such a problem, for example, it is conceivable that the guide rail 6 is positioned behind the lock hole 11g to form an intermediate position lock hole. With such a structure, when the lock release lever 20 is returned to the lock operation position when the luggage floor 4 is pulled out to the intermediate position (position ahead of the maximum pull-out position), the lock pin 11e becomes the lock hole for the intermediate position. Since it engages (locks), the luggage floor 4 can be temporarily stopped.
However, the luggage floor 4 can be stopped at the intermediate position in this way only when the lock release lever 20 is returned to the lock operation position when the intermediate position is reached, and the lock release lever 20 is moved to the lock operation position. When it is slid rearward as it is without returning, the luggage floor 4 slides all the way to the maximum drawing position.

  It is an object of the present invention to always stop the slide deck at an intermediate position regardless of the operation state of the operation handle when the slide deck located at one of the storage position and the maximum pull-out position is slid toward the other position. An object of the present invention is to provide a vehicular slide deck device including an intermediate lock mechanism that can be used.

According to the first aspect of the present invention, when the slide deck is slid to the intermediate position after the lock by the lock lever and the engaging portion for the storage position is released, the operation handle is unlocked from the lock operation position by the action of the lock lever control mechanism. Regardless of the lock operation position, the lock lever moves to the lock position and engages (locks) to the intermediate position engaged portion.
Therefore, it is possible to prevent the slide deck from sliding vigorously to the maximum drawing position.
On the other hand, according to the invention of claim 3, it is possible to prevent the slide deck from sliding at a stretch from the maximum drawing position to the storage position side.

According to the second aspect, even when the slide deck is slid from the maximum drawer position to the storage position side, the lock lever control mechanism works when the slide deck reaches the intermediate position, and the operation handle is moved to the lock operation position. The lock lever moves to the lock position and engages with the engaged portion for the intermediate position regardless of whether it is in the unlock operation position.
Therefore, it is possible to prevent the slide deck from sliding rapidly to the storage position.

The unlock operation position of the operation handle is a position for unlocking.
However, when the intermediate lock is performed with the operation handle being in the unlock operation position, the intermediate lock cannot be released unless the operation handle is once moved to the lock operation position. Therefore, it is possible to further reduce the risk that the slide deck is pulled out to the maximum pulling position (or storage position).

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In addition, the front-back direction and the left-right direction in description of this embodiment are based on the arrow-line direction described in the figure.
A rear opening 11 is formed on the rear surface of the automobile 10, and an upper edge of the back door 12 having the same front shape as the rear opening 11 is formed around the rotation axis in the left-right direction at the upper edge of the rear opening 11. It is attached to be freely rotatable.
In the vehicle 10, there are two front and rear rows of seats (reference numeral 13 shown in FIG. 1 is the second row seat), and the rear of the second row seat 13 is a luggage room 14. On the upper surface of a metal bottom plate (luggage room floor surface) 15 constituting the bottom surface of the luggage room 14, there is provided a slide deck device SD for slidingly moving the loaded luggage in the front-rear direction.

The slide deck device SD has a structure described below.
A channel-shaped lower rail 17 extending in the front-rear direction is fixed to the upper surface of the metal bottom plate 15 constituting the bottom surface of the luggage room 14 as a pair of left and right. As shown in FIG. 2, at three locations on the inner surface of the left and right lower rails 17, there are a metal storage position locked member 18, an intermediate position locked member 19, and a maximum drawer position locked member 20 (detailed shape). 3), the fixed portion 18a, the fixed portion 19a, and the fixed portion 20a formed at both front and rear end portions are fixed by welding. As shown in FIG. 3, the storage position locked member 18, the intermediate position locked member 19, and the maximum drawer position locked member 20 include a pair of front and rear storage position lock holes 18 b, an intermediate position lock hole 19 b, A lockout hole 20b for the maximum drawing position is formed.
Immediately above the bottom plate 15, a slide deck 22 having substantially the same shape as the planar shape of the luggage room 14 is disposed in a state of being spaced upward from the bottom plate 15. A pair of left and right upper rails 23 are fixed to the lower surface of the slide deck 22, and a pair of left and right rollers 24 are provided on the upper rail 23 so as to be rotatable about a rotation axis in the left and right direction (see FIG. 6 and the like). As shown in FIG. 6 and the like, the left and right upper rails 23 (and rollers 24) are slidably fitted to the corresponding lower rails 17, so that the slide deck 22 can slide in the front-rear direction along the left and right lower rails 17. It is. Specifically, the storage position where the entire slide deck 22 is completely stored in the luggage room 14 (the position shown in FIG. 1), and the maximum where most of the slide deck 22 protrudes from the rear opening 11 to the rear of the automobile 10. It can slide between the drawing positions (not shown).
As shown in FIGS. 1 and 2, the rear end portion of the slide deck 22 is provided with an operation handle 25 having a substantially rectangular shape in plan view and having a finger-hanging recess 26 formed on the upper surface thereof. The operation handle 25 extends in the front-rear direction with respect to the slide deck 22 between a lock operation position shown in FIGS. 1 and 2 and an unlock operation position (not shown) located behind the positions in FIGS. It can slide. Further, a compression coil spring (not shown) that constantly urges the operation handle 25 forward is provided between the slide deck 22 and the operation handle 25, so that the operation handle 25 is always (on the operation handle 25) by this urging force. This means that the operation handle 25 is located at the lock operation position without being put on the hand (hereinafter the same), and is located at the lock operation position (position in FIG. 1).
Further, a front cam member 27 and a rear cam member 28 having a substantially trapezoidal shape in a side view are fixed as a pair of left and right in the vicinity of the left and right intermediate position locked members 19 on the upper surface of the bottom plate 15. As shown in the drawing, a front inclined surface 27a, a front inclined surface 28a, a rear inclined surface 27b, and a rear inclined surface 28b are formed at the front and rear ends of the front cam member 27 and the rear cam member 28, respectively.

Near the front end portion of the lower surface of the slide deck 22, a slider support member 30 having a generally U-shape facing downward is fixed as a pair of left and right (only the right slider support member 30 is shown, and the left slider support member 30 is illustrated. Omitted). As shown in the drawing, a support groove 31 is formed in the center in the vertical direction of the left and right side pieces of the slider support member 30, and an inward lower end support piece 32 projects from the lower ends of the left and right side pieces. It is set up.
Inside the slider support member 30, a rectangular frame-shaped slider 35 is inserted so as to be slidable in the front-rear direction with the lower surface supported by the lower end support piece 32. As shown in the drawing, slide protrusions 36 project from left and right sides of the slider 35, and the left and right slide protrusions 36 are slidably engaged with the left and right support grooves 31 of the slider support member 30, respectively. Both of the bottom plate portions of the slider 35 are formed with an engagement / disengagement pin support hole 37 and a cam pin support hole 38 that are circular in plan view, and a wire locking projection 39 projects from the rear end portion of the ceiling portion of the slider 35. It is. Further, both ends of the tension spring S1 are engaged with the spring hooking hole 33 formed in the front end of the ceiling portion of the slider 35 and the ceiling portion of the slider support member 30.
Since the front end of the operation wire W that is disposed immediately below the slide deck 22 and that has a rear end connected to the operation handle 25 is fixed to the wire locking protrusion 39 (see FIG. 7 and the like), the position of the slider 35 Is interlocked with the movement of the operation handle 25. That is, when the operation handle 25 is located at the lock operation position, no tensile force is transmitted to the slider 35 via the operation wire W, so the slider 35 is moved to its initial position (figure) by the urging force (tensile force) of the tension spring S1. 7 position). On the other hand, when the operation handle 25 is slid rearward to the unlock operation position, this force is transmitted to the slider 35 via the operation wire W, so that the slider 35 is moved to the slide position (see FIG. 8, slider support member 30 from the initial position). Slide slightly to the rear). Since the tension spring S1 exists between the slider support member 30 and the slider 35, the slider 35 cannot move forward from the initial position with respect to the slider support member 30, and the operation handle 25 reaches the unlock operation position. When moved, the urging force of the tension spring S1 is applied, so that the slider 35 cannot move backward from the slide position.
Lifting members (engagement / disengagement members) 40 are supported on the left and right sliders 35 so as to be vertically movable. The elevating member 40 is integrally provided with a substrate 41 having a substantially rectangular shape in plan view, and an engagement / disengagement pin 42 and a cam pin 43 that both protrude downward from the lower surface of the substrate 41. The engaging / disengaging pin 42 has a cylindrical shape, and a front inclined cam surface 44 and a rear inclined cam surface 45 are formed at the lower end portion of the cam pin 43. As shown in the drawing, the engagement / disengagement pin 42 is fitted to the engagement / removal pin support hole 37 of the slider 35 so as to be movable up and down, and the cam pin 43 is fitted into the cam pin support hole 38 so as to be movable up and down. Further, since the pair of left and right compression coil springs S2 are contracted between the upper surface of the substrate 41 and the ceiling surface of the slider 35, the lower surface of the substrate 41 is always in contact with the bottom plate portion of the slider 35.

In the vicinity of the left and right slider support members 30 on the lower surface of the slide deck 22, support members (not shown) that support a rotating shaft 51 extending in the front-rear direction are fixed as a pair of left and right. 5 and 6 are supported so as to be rotatable around the rotation shaft 51 (only the right lock lever 50 is shown in the figure. The left lock lever 50 is the right lock lever 50). And symmetrical shape). The lock lever 50 is provided with a base portion 52 having a downward U-shape. At the outer end of the base portion 52, the storage position lock member 18, the intermediate position lock member 19, and the front end of the maximum pull-out position lock member 20 are provided. A pair of front and rear lock claws 53 that can be engaged and disengaged are respectively projected from the storage position lock hole 18b, the intermediate position lock hole 19b, and the maximum pull-out position lock hole 20b. Further, a pair of front and rear support protrusions 55 having a rotation support hole 54 through which the rotation shaft 51 is rotatably penetrated project from the upper portion of the base 52.
The left and right lock levers 50 include a lock position where the lock claw 53 is substantially horizontal and the inner wall portion 56 of the base portion 52 is substantially vertical (the position indicated by the solid line in FIG. 6), and an unlocking position where the lock claw 53 moves downward. It can be rotated between the lock position (the position of the phantom line in FIG. 6). In addition, a torsion coil spring (not shown) is provided between the lock lever 50 and the rotary shaft 51 to urge the lock lever 50 to always rotate toward the lock operation position. It is always in the lock position (position in FIG. 1).
Further, the front end portion of the rotating lever support bar 58 shown in FIG. 4 is fixed to the lower surface of the slide deck 22 as a pair of left and right (only the right rotating lever support bar 58 is shown in FIG. 4 and the left rotating lever support bar 58 is shown. Is omitted). The rear end portion of the rotating lever support bar 58 is a rotating shaft portion 59 that extends upward and is located immediately after the lock lever 50.
A rotation center hole 61 formed in the rotation lever 60 is rotatably fitted to the rotation shaft portion 59. The rotary lever 60 includes a pressing portion 62 and a cam pin support portion 63 that are substantially parallel to each other, and an intermediate connecting portion 64 that connects the rear end portion of the pressing portion 62 and the front end portion of the cam pin support portion 63. Further, the intermediate connecting portion 64 is provided with a rotation center hole 61 and an engagement hole 65 that is located on the side of the rotation center hole 61 and that allows the lower end of the engagement / disengagement pin 42 to be engaged / disengaged. The rotation lever 60 can rotate around the rotation shaft portion 59 between a non-pressing position shown in FIGS. 7, 12, and 16 and a pressing position shown in FIGS. Further, a torsion coil spring (not shown) is provided between the rotation shaft portion 59 and the rotation lever 60, and this torsion coil spring urges the rotation lever 60 to rotate toward the non-pressing position.
Among the members described above, the front cam member 27, the rear cam member 28, the slider support member 30, the slider 35, the elevating member 40, the rotation lever support bar 58, the rotation lever 60, the tension spring S1, the compression coil spring S2, and the rotation A torsion coil spring that rotationally biases the lever 60 is a component of the lock lever control mechanism CM.

Next, the operation of the slide deck device SD configured as described above will be described.
First, an operation for sliding the slide deck 22 located at the storage position to the maximum drawing position will be described.
When the back door 12 is located at a fully closed position that closes the back opening 11, the slide deck 22 is located at a storage position (position in FIG. 1) that is completely stored in the luggage room 14.
Further, since the operation handle 25 is located at the lock operation position (because it is not operated), the slider 35 is located at the initial position as shown in FIGS. Is engaged with the engaging hole 65 to hold the rotating lever 60 in the non-pressed position. Since the pressing portion 62 of the rotary lever 60 located at the non-pressing position does not press the inner wall portion 56 of the lock lever 50, the lock lever 50 is held at the lock position by the biasing force of the torsion coil spring, and a pair of lock claws 53 is provided. Are respectively engaged (locked) with the corresponding storage position lock holes 18b of the storage position locked member 18. Thus, when the back door 12 is located at the fully closed position that closes the back opening 11, the lock lever 50 holds the slide deck 22 in the storage position so as not to slide.

When the passenger (or driver or the like) hangs his / her hand on the finger hook recess 26 and slides the operation handle 25 positioned at the lock operation position backward to the unlock operation position after the back door 12 is opened, the operation wire The slider 35 linked to the operation handle 25 slides backward from the initial position to the slide position via W. Then, since the elevating member 40 supported by the slider 35 slides back together, the rotating lever 60 is rotated to the pressing position by the engagement / disengagement pin 42 of the elevating member 40 (see FIG. 8). Then, since the pressing portion 62 of the rotating lever 60 presses the inner wall portion 56 of the lock lever 50 toward the center in the vehicle width direction, the lock lever 50 rotates to the unlock position, and the lock claw 53 of the lock lever 50 The storage position lock member 18 escapes from the storage position lock hole 18b (see the phantom line in FIG. 6 and FIG. 8). Then, the slide deck 22 can be slid rearward, so that the slide deck 22 slides backward when the slide deck 22 is pulled backward while the finger-hanging concave portion 26 is held at the unlocking operation position.
Then, as shown in FIG. 9, when the slide deck 22 reaches just before the intermediate position (position where the lock lever 50 locks the intermediate position locked member 19), the rear inclined cam surface 45 of the cam pin 43 becomes the front cam member. 27 abuts on the front inclined surface 27a. When the slide deck 22 is further slid rearward, as shown in FIGS. 10 and 11, the cam pin 43 rises along the front inclined surface 27a while bringing the rear inclined cam surface 45 into sliding contact with the front inclined surface 27a. The cam pin 43 rides on the upper surface of the front cam member 27. Then, the substrate 41 (the position of the elevating member 40 at this time is the engaged position) that has been in contact with the bottom plate portion of the slider 35 resists the urging force of the compression coil spring S2 as shown in FIG. It is separated upward from the bottom plate part (the position of the elevating member 40 at this time is the disengaged position), and the engagement / disengagement pin 42 is further escaped upward from the engagement hole 65 of the rotation lever 60. Then, the rotation lever 60 is rotated back to the non-pressing position by the rotation biasing force of the torsion coil spring, and the pressing force from the pressing portion 62 to the inner wall portion 56 disappears, so that the rotation lever 60 is locked by the rotation biasing force of the torsion coil spring. The lever 50 rotates to the lock position side, and the lock claw 53 of the lock lever 50 contacts the inner surface of the intermediate position locked member 19 (see FIGS. 11 and 12). When the slide deck 22 reaches the intermediate position shown in FIG. 13, the lock claw 53 of the lock lever 50 engages (locks) with the corresponding intermediate position lock hole 19 b, and the cam pin 43 is located behind the front cam member 27. Move to. At this time, since the slider 35 is located at the slide position, the engagement / disengagement pin 42 is located behind the engagement hole 65. Therefore, the lower end portion of the engagement / disengagement pin 42 pushed back downward by the urging force of the compression coil spring S2 contacts the upper surface of the cam pin support portion 63 (becomes disengaged from the engagement hole 65), and the elevating member 40 is It stops at the position shown in FIG.

When the intermediate lock is performed by the lock lever 50 and the intermediate position locked member 19 in a state where the operation handle 25 is positioned at the unlock operation position in this way, the slide deck 22 cannot slide from the intermediate position.
In order to release this locked state, the operation handle 25 is once returned to the lock operation position by releasing the hand from the finger hanging recess 26. Then, as shown in FIG. 14, the slider 35 slightly moves forward with respect to the slider support member 30 from the slide position to the initial position (the engagement / disengagement pin 42 slides forward on the upper surface of the cam pin support portion 63). The front and rear (and right and left) positions of the engagement / disengagement pin 42 and the engagement hole 65 coincide, the engagement / disengagement pin 42 is fitted again into the engagement hole 65 by the urging force of the compression coil spring S2, and the substrate 41 is moved to the slider 35. Again contact the bottom plate (see FIGS. 15 and 16). When the engagement / disengagement pin 42 is fitted in the engagement hole 65 in this manner, the operation of the operation handle 25 is transmitted again to the rotary lever 60 via the operation wire W, the slider 35, and the elevating / lowering member 40 (the engagement / disengagement pin 42). Therefore, when the operation handle 25 is pulled again to the unlocking operation position, as shown in FIG. 17, the rotating lever 60 rotates to the pressing position and the pressing portion 62 rotates the locking lever 50 to the unlocking position. The state is released.
The operation so far is the case where the slide deck 22 is slid to the intermediate position while the operation handle 25 is held at the unlock operation position even after the lock position of the storage position locked member 18 by the lock lever 50 is released. Is. However, after the locked state of the locked member 18 for the storage position by the lock lever 50 is released and the slide deck 22 is slightly slid rearward, the operation handle 25 is returned to the lock operation position, and the operation handle 25 is moved to the lock operation position. Even when the slide deck 22 is slid rearward while being held, the intermediate lock is forcibly performed. That is, in this case, at the moment when the cam pin 43 gets over the front cam member 27 and moves to the rear of the front cam member 27, the lock lever control mechanism CM does not go through the state of FIG. Even in this case, the intermediate lock is surely executed. In this case, since the operation handle 25 is already positioned at the lock operation position, the intermediate lock state can be immediately released by pulling the operation handle 25 to the unlock operation position.

When the slide deck 22 is slid rearward with the operation handle 25 held in the unlock operation position after the intermediate lock is released, the cam pin 43 rides on the rear cam member 28 as shown in FIG. The lock lever 50 rotates to the lock position because it escapes upward from the engagement hole 65 of the rotation lever 60.
When the engagement / disengagement pin 42 moves rearward of the rear cam member 28 by moving the slide deck 22 further rearward (because the slider 35 is positioned at the slide position), it is positioned rearward of the engagement hole 65. The lower end portion of the engaging / disengaging pin 42 is in contact with the upper surface of the cam pin supporting portion 63 (becomes disengaged from the engaging hole 65. The same state as FIG. 13). When the slide deck 22 reaches just before the maximum pull-out position, the lock claw 53 of the lock lever 50 positioned at the lock position slides on the side surface of the locked member 20 for the maximum pull-out position, and the slide deck 22 reaches the maximum pull-out position. At this moment, the lock claw 53 of the lock lever 50 engages (locks) with the maximum pull-out position lock hole 20b of the maximum pull-out position locked member 20 (see FIG. 19), so that the slide deck 22 is held at the maximum pull-out position. Is done.
Thereafter, when the operation handle 25 is returned to the lock operation position by releasing the finger from the finger catching recess 26, the slider 35 located at the slide position returns to the initial position, so that the engagement / disengagement pin 42 is connected to the cam pin support portion 63. When the front / rear (and right / left) positions of the engagement / disengagement pin 42 and the engagement hole 65 coincide with each other, the engagement / disengagement pin 42 is re-fitted into the engagement hole 65 by the urging force of the compression coil spring S2. The substrate 41 again comes into contact with the bottom plate portion of the slider 35 (see FIG. 19).
After the intermediate lock was released and the slide deck 22 was moved slightly rearward, the operation handle 25 was returned to the lock operation position, and the slide deck 22 was slid rearward while holding the operation handle 25 in the lock operation position. In this case, the engagement / disengagement pin 42 is fitted into the engagement hole 65 by the urging force of the compression coil spring S2 at the moment when the cam pin 43 gets over the rear cam member 28, so that the moment when the slide deck 22 reaches the maximum drawing position. The lock lever control mechanism CM is in the state shown in FIG.

Next, an operation for sliding the slide deck 22 moved to the maximum drawing position to the storage position will be described.
When the operation handle 25 located at the lock operation position is moved to the unlock operation position, the lock lever 50 is rotated to the unlock position, so that the lock of the locked member 20 for the maximum drawing position by the lock lever 50 is released. The
When the slide deck 22 is slid to the position immediately after the intermediate position while the operation handle 25 is held in the unlocked position, the cam pin 43 slides the front inclined cam surface 44 against the rear inclined surface 28b as shown in FIG. It rides on the upper surface of the side cam member 28. Then, since the engagement / disengagement pin 42 escapes upward from the engagement hole 65, the lock lever 50 rotates to the lock position.
When the slide deck 22 reaches the intermediate position shown in FIG. 21, the engagement / disengagement pin 42 comes into contact with the upper surface of the cam pin support portion 63 by the urging force of the compression coil spring S2, and the lock claw 53 of the lock lever 50 is in the intermediate position. The locking member 19 is engaged (locked) with the locking hole 19b for the intermediate position (see FIG. 21).
In order to release the intermediate lock state, the operation handle 25 is once returned to the lock operation position by releasing the hand from the finger hooking recess 26. Then, since the slider 35 located at the slide position returns to the initial position, the engagement / disengagement pin 42 slides forward on the upper surface of the cam pin support portion 63, and the front / rear (and left / right) of the engagement / disengagement pin 42 and the engagement hole 65. ) At the moment when the positions coincide with each other, the engagement / disengagement pin 42 is re-fitted into the engagement hole 65 by the biasing force of the compression coil spring S2, and the substrate 41 comes into contact with the bottom plate portion of the slider 35 again (see FIG. 22). The vertical back surface state and the planar state are the same as those in FIGS. 15 and 16). When the engagement / disengagement pin 42 is fitted in the engagement hole 65 in this manner, the operation of the operation handle 25 is transmitted again to the rotary lever 60 via the operation wire W, the slider 35, and the elevating / lowering member 40 (the engagement / disengagement pin 42). Therefore, when the operation handle 25 is pulled again to the unlock operation position, the lock lever 50 rotates to the unlock position, and the intermediate lock state is released.
In addition, after the locked state of the locked member 20 for the maximum drawing position by the lock lever 50 is released and the slide deck 22 is slightly slid forward as in the case of sliding from the storage position to the maximum drawing position side described above. Even when the operation handle 25 is returned to the lock operation position and the slide deck 22 is slid forward while the slide deck 22 is held at the lock operation position, the slide deck 22 is moved to the intermediate position (position in FIG. 22) at the moment. An intermediate lock is forced.

When the operation handle 25 is slid to the unlock operation position after the state shown in FIG. 22 is reached, the lock lever 50 rotates to the unlock position, so that the intermediate lock is released.
When the slide deck 22 is slid forward with the operation handle 25 held in the unlock position, the cam pin 43 rides on the upper surface of the front cam member 27 while sliding the front inclined cam surface 44 against the rear inclined surface 27b. The engagement / disengagement pin 42 is released upward from the engagement hole 65, and the lock lever 50 is rotated to the lock position. When the cam pin 43 gets over the front cam member 27 and moves to the front of the front cam member 27, the engagement / disengagement pin 42 comes into contact with the upper surface of the cam pin support portion 63 by the urging force of the compression coil spring S2.
When the slide deck 22 is slid to the storage position while the operation handle 25 is held in the unlock operation position, the lock claw 53 of the lock lever 50 is moved to the storage position of the storage position locked member 18 at the moment the storage position is reached. The slide deck 22 is held in the storage position by engaging (locking) with the lock hole 18b. Further, when the operation handle 25 is returned to the lock operation position after that, the slider 35 located at the slide position returns to the initial position, so that the engagement / disengagement pin 42 slides forward on the upper surface of the cam pin support portion 63. At the moment when the front and rear (and right and left) positions of the removal pin 42 and the engagement hole 65 coincide with each other, the engagement / disengagement pin 42 is fitted again into the engagement hole 65 by the urging force of the compression coil spring S 2, and the substrate 41 is moved to the slider 35. It contacts the bottom plate again (see FIGS. 5, 6, and 7).
As in the case of sliding from the storage position to the maximum drawing position, the intermediate lock is released and the slide deck 22 is slightly slid forward, and then the operation handle 25 is returned to the lock operation position. Even when the slide deck 22 is slid forward while the lever is held at the lock operation position, the lock at the storage position is executed at the moment when the slide deck 22 reaches the storage position, and the lock lever 50 and the lock lever control mechanism CM are 5, 6, 7.

In the present embodiment, stoppers (not shown) are fixed to the front and rear ends of the left and right lower rails 17. Therefore, when the slide deck 22 slides to the storage position or the maximum drawer position, the lock lever 50 should be locked for the storage position. When not engaging with the hole 18b or the lock hole 20b for the maximum drawer position, the left and right rollers 24 abut against the stopper, thereby preventing the slide deck 22 from sliding forward from the storage position or backward from the maximum drawer position. To do. Whether the operation handle 25 is positioned at the lock operation position or the unlock operation position when the slide deck 22 is slid from the storage position to the maximum extraction position or when the slide deck 22 is slid from the maximum extraction position to the storage position. Regardless of this, when the slide deck 22 reaches the intermediate position, the lock lever 50 engages (locks) with the intermediate position locked member 19 to always stop the slide deck 22 at the intermediate position. It is possible to reliably prevent the roller 24 from violently colliding with the stopper and damaging the roller 24.
Furthermore, the unlocking operation position of the operation handle 25 is a position for unlocking. However, when the intermediate lock is performed with the operation handle 25 positioned at the unlocking operation position, the operation handle 25 is temporarily locked. The intermediate lock cannot be released unless it is moved to the operating position. Therefore, the risk that the slide deck 22 is pulled out all the way to the maximum pull-out position or storage position is further reduced.

Although the present invention has been described based on the above embodiment, the present invention can be implemented with various modifications.
For example, in the above embodiment, intermediate locking is performed only at one location, but a plurality of intermediate position locked members 19 are provided on the lower rail 17, and the same number of front cam members 27 and By fixing the rear cam member 28 on the bottom plate 15, intermediate locking may be forcibly executed at a plurality of locations.
Further, by omitting the rear cam member 28, the intermediate lock may not be forcibly performed when sliding from the maximum drawing position to the storage position side, or by omitting the front cam member 27, The intermediate lock may not be forcibly performed when sliding from the storage position to the maximum drawing position.
Further, instead of the storage position lock hole 18b, the intermediate position lock hole 19b, and the maximum pull-out position lock hole 20b, an engagement protrusion (engaged portion) is formed on the lower rail 17, and each engagement with the lock lever 50 is made. An engagement hole that can be engaged with and disengaged from the protrusion may be formed.
