The cam groove 11A and the cam pin 15A form a front elevating cam mechanism 17F together with the cam grooves 11A and 11B. The cam pin 15B constitutes a rear cam means 18B for raising and lowering the rear part of the lifter IO.

An interlocking plate 2 is attached to the two shaft portions 14 on one side of the slider 12.
0 is fitted, and this interlocking plate 20 has pin portions 21A at the front and rear.
, 21B are provided protrudingly. A timing rod 59, which will be described later, is connected to the pin portion 21B.

Reference numeral 22 denotes a position setting member, in which the front part 2 and the front part 2 are arranged in the center part.
A cam groove 23 is formed in which 1A engages, and a retaining portion 24 is formed in the lower rear portion. The engaging portion 24 can be freely engaged with and disengaged from a cutout-shaped engaged portion 25 formed in the guide rail 7, and the cam groove 23 has a rear portion 23a formed in a descending shape, and a front pin portion 21A that is connected to the cam groove 23. By entering the rear part 23a of
The engaging portion 24 is configured to be disengaged upward from the engaged portion 25, and the front pin portion 21^ and the cam groove 23 act as actuating means 26 for causing the position setting member 22 to set and release the position. It has become.

The front portion of the position setting member 22 is connected via a guide body 27 to a front guide member 28 so as to be relatively rotatable. The position setting member 22, the guide body 27, and the front guide member 28 are each guided by the guide rail 7 so as to be slidable back and forth.

A cam hole 29 having a substantially triangular shape (or a rear elongated hole may be formed) is formed in the front guide member 28.
A pin portion 30 protruding from the lifter IOF at 9 is connected to the roller 3.
1, and the bottle portion 30 is allowed to move slightly back and forth and up and down within the cam hole 29, and these constitute a front guide means 32.

A drive wire 34 is connected to the slider 12F via a stopper 33, and the drive wire 34 is pushed and pulled by a drive device (not shown) fixed to the roof 1 side.

In the front opening/closing device 8F, the slider 12F is moved rearward by pulling the drive wire 34, and the lifter IOF is tilted up from the cover member closed state shown in FIG. 1.2.9A via the elevating cam mechanism 17F. Cam pin 15
As A and 15B move within the cam grooves 11A and IIB, the rear part of the lifter 10 rises greatly, but the front part also rises slightly, and the entire lifter moves up while tilting up.
It separates from the front seal body 35 on the inner peripheral side of the mounting frame 3 (Fig. 4.9B).

While the lifter IOF is rising, the bottle part 21A moves along the straight part of the cam groove 23, so the actuating means 26 is not actuated, the position setting member 22 and the front guide member 28 remain stationary, and the bottle part 30 moves in the cam hole 29. The lifter IOF moves backward by the amount that is allowed to move back and forth within the cover member 6F, and therefore, the movement locus of the front end of the cover member 6F is from the upper surface of the front seal body 35 to the upper rear direction.

Since the bottle portion 30 touches the rear wall 29a of the cam hole 29,
It restricts further backward movement of the lifter IOF and serves as a fulcrum for tilting while allowing a slight upward movement.

When the slider 12F is further moved backward after the lifting of the lifter LOP is almost completed, the cam pins 15A and 15B enter the rear portions of the cam grooves 11A and 11B, and the pin portion 21A enters the downwardly inclined end 23a of the cam groove 23, and is activated. Means 26
operates to move the engaging portion 24 of the position setting member 22 to the engaged portion 2.
Remove from 5. From this state B (shown in FIG. 4) onwards, the position setting member 22, front restriction member 28, and lifter IOF are interlocked with the backward movement of the slider 12F, and the cover member 6F is in the tilted open position and the opening 2 open up
(Figure 90.9D).

The closing operation by the front opening/closing device 8F pushes the drive wire 34 to move the slider 12F forward.

Since the position setting member 22 does not have an engaged part that should be engaged by the engaging part 24 in the middle of the guide rail 7, the slider 12F
, and the lifter IOP is also pushed via the front guide means 32.

When the cover member 6F reaches near the front end of the opening 2, the engaging part 24 engages with the engaged part 25, and the straight part of the cam groove 23 of the position setting member 22 becomes approximately horizontal, so that the pin part 21 The bin portion 30 moves inside the cam hole 29 toward the front end, and the cam pins 15^ and 15B move inside the cam grooves 11A and IIB, thereby lowering the lifter IOF and the cover member 6F.

In the rear opening/closing device 8R shown in Fig. 1.3.5, the lifter IOH fixed to the lower left and right sides of the rear cover member 6R is provided with a cam pin 3 in the front part and a cam groove 39 is formed in the middle part. The slider 12H has a cam groove 40 that engages with the cam pin 38 and a cam pin 41 that engages with the cam groove 39.
The cam pin 38 and the cam groove 40 form the front cam means 18RA, and the cam groove 39 and the cam pin 4! These form rear cam means 18RB, and these form a rear elevating cam mechanism 17R that raises the rear cover member 6R as a whole while tilting it upward.

The positioning member 22R has a cam groove 43 in which the bottle portion 42 protruding from the slider 12R is engaged, and the cam groove 43 has an upwardly rising rear portion. Reference numeral 44 is formed at the rear upper part and can be freely engaged with and disengaged from an engaged portion 45 formed on the upper side of the guide rail 7, thereby forming an actuating means 26R.

A front guide member 28R, which is relatively rotatably connected to the front part of the position setting member 22R via a guide body 46, is connected to the lifter I.
It has a cam hole 47 into which one end of a cam pin 38 protruding from the OR is inserted.

The cam hole 47 is a circular arc hole with an upward slope, and the cam pin 3
8 to the rear and upward, forming a tilt fulcrum for the rear cover member 6R, and these constitute a front guide means 32R.

Slider 121? The rear end of the timing rod 59 is connected to the front end of the timing rod 59 via a pivot shaft 49. As shown in Fig. 5.7, this timing loft 59 is slidably disposed within the guide rail 7, and its front part is curved in an L shape (or an L shape), and from the front part to the rear part. over L
A guide groove 60 is formed in the shape of a letter (or an oval shape), and a locking portion 61 that protrudes downward is formed in the middle.

The guide groove 60 is engaged with the pin portion 21B of the connecting plate 20, and when the pin portion 21B is in the downward groove portion 60a of the guide groove 60, the longitudinal movement of the front slider 12F is transmitted to the rear slider 12H. be done.

The guide rail 7 has a downward protrusion 59 of the timing loft 59 when the rear slider 12R moves to the rearmost position.
A, a notch 62 into which the locking part 61 is inserted, and a locked part 63 are formed on the lower side of the rail, and a lowering means 64 for pressing the timing rod 59 downward is formed on the upper side of the rail. This lowering means 64 is configured to lower an arc-shaped elastic body 65 using a spring 66.

The timing rod 59 has a downward protrusion 59a and a locking portion 6.
1 enters the notch 62 and the locked portion 63, the guide groove 6
0 straight part 60b becomes parallel to the guide rail 7,
The bottle portion 21B extends from the downward groove portion 60a to the straight portion 60.
b, and becomes able to slide backwards. Therefore, the backward movement of the front slider 12F is no longer transmitted to the rear slider 12R.

The locking portion 61, the locked portion 63, the bullet lowering means 64, etc.,
When the rear slider 12R reaches the rearmost position, it serves as a position fixing means 67 for fixing the relative position of the timing rod 59 with respect to the guide rail 7, and the rear cover member 6R becomes immovable. Furthermore, with the structure in which the straight portion 60b of the guide groove 60 and the straight portion 60b are made parallel to the guide rail 7 when the position fixing means 67 is activated, the front slider 12F is aligned with respect to the timing rod 59 after the position fixing means 67 is activated. This is an independent slider moving means 68 that allows backward movement.

In the rear opening/closing device 8R as well, the tilt fulcrum of the rear cover member 6R is arranged behind the front end, but since the rear cover member 6R performs an entire upward movement in which the front part also rises during the tilt operation, the front part Both sides do not fall below the upper surface of the mounting frame 3.

The tilt opening/closing operation of the rear opening/closing device 8R starts from the closed state shown by the solid line in FIG. 3.9 in synchronization with the tilting operation of the front cover member 6F.

When the front slider 12F starts to move backward, the timing loft 59 is moved backward via the bin part 21B of the connecting plate 20, and is pushed by the timing rod 59 to move the rear slider 12.
R is moved, and the lifter 10R1, that is, the rear cover member 6R is tilted up and raised as a whole through the cam groove 40 and the cam bin 41.

After the front and rear cover members 6F, 6R are raised almost completely, when the front and rear sliders 12F, 12R move further rearward, the cam portion 42 rotates the position setting member 22R backward and downward via the cam groove 43, and the engagement portion 44 is separated from the engaged portion 45.

Thereafter, the rear slider 12R moves rearward together with the rear lifter IOR, thereby causing the front and rear cover members 6F, 6R to
remain parallel in the tilted position and move together to the rear of the opening 2, opening the opening 2.

When the rear cover member 6R reaches the rear part of the opening 2, the timing rod 59 is pressed downward by the bullet lowering means 64 (FIG. 9C), and the locking portion 61 engages with the locked portion 63, so that the timing rod 59 moves back and forth. It becomes immobile, and the backward movement of the rear cover member 6R is stopped. After that, the backward movement of the front slider 12F continues,
Only the front cover member 6F moves rearward independently until the pin portion 21B reaches the rear end of the straight portion 60b of the guide groove 60.

In the closing operation of the rear cover member 6R, the pin portion 21B enters the downward groove portion 60a due to the forward movement of the front slider 12F, and lifts the front portion of the timing rod 59 against the bullet lowering means 64, and the locking portion 61 is closed. The process starts after the locked portion 63 is disengaged.

It should be noted that the present invention is not limited to the embodiments described above, and can be modified in various ways. For example, the number of cover members 6 may be three or more, the bullet lowering means 64 may be made of a plate spring, or the timing rod 59 may have its own weight, or the pin portions 20A and 20B may be attached to the front slider 12F without providing the connecting plate 20. It can be set up. Moreover, instead of providing the locking part 61 and the locked part 63, a downward protrusion 59a and a notch 6 are provided.
2 may be used as a locking part and a locked part, respectively.

(Effects of the Invention) According to the present invention detailed above, since the front slider that is driven back and forth and the rear slider on the driven side are connected by the timing rod, the positioning of the front and rear cover members is extremely easy and accurate. When the rear slider reaches the rearmost position, the position fixing means fixes the position relative to the guide rail.
The rearmost position of the rear cover member can be accurately set, and after the rearmost position of the rear cover member is set, only the front cover member is moved, so that driving becomes light. Further, the structure in which a plurality of cover members are simultaneously tilted up and moved backward, and the front cover is moved independently is simple, and manufacturing and assembly are facilitated.
