In addition, the water stop material 18b is urged by a spring to a position where it does not come into contact with the surface of the front door plate 31 on the opening 11 side.

Then, the sliding door 3a slides to close the opening 11, and the tip of the front door panel 31 abuts against the door stopper 18a. When it slides further, as shown in FIG. 17, the sliding door front end door stopper 18 rotates around the hinge, and the water stopper 18b is pressed against the opening 11 side wall surface of the front door panel 31 while elastically deforming, preventing the entry of rain and wind from the opening 11 side.

As shown in FIGS. 17 and 18, the door guide fitting 10 has an L-shaped cross section that is shorter than the vertical dimension of the front door plate 31, and has one side of the L shape and the front end door stopper member 18 of the sliding door. In between, as shown in FIG. 17, the front end of the front door plate 31 of the sliding door 3a enters, and together with the sliding door front end door contact member 18, restricts the movement of the front end of the front door plate 31 in the front-rear direction of the garage. It looks like this.

The door driving means 4 includes a running rail 41, a sliding portion 42, and a transmission arm 43, as shown in FIGS. 7 and 8.
The traveling rail 41 is provided horizontally along the side wall of the garage 1 below the side wall guide part 52 and parallel to the side wall guide part 52.

The slide portion 42 is supported so as to be slidable in the longitudinal direction of the running rail 41, and includes a motor (not shown) that is driven by remote control and a sprocket that is rotationally driven by the motor and meshes with the chain 44. The sprocket is rotated by a motor to move back and forth along the travel rail 41.
As shown in FIG. 8, the transmission arm 43 has one end pivotally supported by the slide portion 42 and the other end pivotally supported by the rear door plate 32.

In other words, the door driving means 4 slides the entire sliding door 3a toward the opening 11 by the sliding portion 42 sliding along the running rail 41 toward the opening 11, and the transmission arm 43 pushes the rear door panel 32 toward the opening, thereby sliding the entire sliding door 3a toward the opening 11, and slides the sliding portion 42 along the running rail 41 in a direction away from the opening 11, thereby sliding the sliding door 3a along the side wall 16.
In the figure, reference numerals 19 and 37 denote elastic materials such as elastomer resin that prevent rainwater and wind from entering the garage.

The following is a detailed explanation of the movement of each part when the sliding door 3a of this sliding door device 2a is closed.

With the front door panel 31 in an open, locked state as shown in Figure 17 and the sliding door 3a in a position along the side wall 16 as shown in Figure 2, the motor of the door drive means 4 is driven by a remote control, a wall-mounted switch, etc. to slide the sliding portion 42 toward the opening 11, and the rear door panel 32 is advanced toward the opening 11 via the transmission arm 43.
That is, this causes the sliding door 3 a to slide along the upper guide rail 5 in a direction to close the opening 11 .

As the roller body 36a of the running roller 36 of the front door panel 31 and each intermediate door panel 33 moves through the side wall side guide portion 52 and the curved guide portion 53 to the opening side guide portion 51, their surfaces become parallel to the opening side guide portion 51 and the guide protrusion 35 protruding from the lower end abuts against the first door stop rail 13.
In addition, when the sliding door 3a is in the opening closing position, the guide protrusion 35 of each middle door panel 33 fits between the first door stop rail 13 and the door guide 15, and the position of the middle door panel 33 is restricted vertically and also laterally by the other door panels 33 (31, 32) connected thereto.

On the other hand, as the sliding door 3a slides, the front door plate 31 presses the door stop part 18a with its front end, rotates the sliding door front end door stop member 18, and as shown in FIG. The front end portion is fitted between the sliding door front end door contact member 18 and the door guide fitting 10, and its position is regulated.

On the other hand, in the rear door plate 32, the running roller 36 on the front end side enters into the opening side guide part 51 like the other door plates 31, 33, but the running roller 36 attached to the roller support plate 38 Since the roller body 36a is located rearward from the rear end of the rear door plate 32, the roller body 36a does not enter the opening side guide portion 51.
Then, the roller main body 36a of the running roller 36 attached to the intermediate door plate 33 adjacent to the rear door plate 32 enters the opening side guide portion 51, and a part of the guide protrusion 35 of the intermediate door plate 33 moves into the first When the slide part 42 slides further while being inserted between the door stop rail 13 and the door guide 15, the rear door plate 32 slides in the direction of the opening 11 of the slide part 42, and the front door plate 31 While further sliding the intermediate door plate 33 along the opening side guide part 51, the transmission arm 43 moves the rear edge of the rear door plate 32 toward the vertical door contact part 17 so that the adjacent intermediate door It rotates around the connection part 30 with the plate 33.

Also, with this rotation, as shown in FIG. 11, the locking head 82 of the second engaging part 8a first faces the notch hole 71 of the first engaging part 7a, and as shown in FIG. , the locking head 82 enters into the cavity 74, and the columnar portion 81 relatively moves in the direction of the locking groove 72.
Then, as shown in FIGS. 13 and 14, when the columnar part 81 has moved until it almost touches the bottom of the U-shape of the locking groove 72, the guide protrusion 35 of the rear door plate 32 is aligned with the first door stop rail. 13, the opening 11 is completely closed by the sliding door 3a as shown in FIGS. 1 and 3 to 5, and the first engaging portion 7a and the second engaging portion 8a are engaged. state.
In this state, the upper end of the rear door plate 32 is held closed by the transmission arm 43, as in the conventional case, and the lower end of the rear door plate 32 is held closed by the transmission arm 43, as in the conventional case, and the lower end of the rear door plate 32 is held closed by the transmission arm 43, and the lower end of the rear door plate 32 is held closed by the transmission arm 43, as in the conventional case. Also, since the locking head 82 is locked to the locking wall 73, it hardly bends.

In addition, when the sliding door 3a has the opening 11 completely closed as described above, the door driving means 4 may stop driving due to a power outage or failure, making it impossible to enter or exit the garage 1, or the sliding door 3a may not be able to enter or exit the garage 1. If the need arises, insert the key into the keyhole from outside the garage 1 to unlock the lock 31d, or operate the operating knob from inside the garage 1 to unlock the lock 31d, as shown in Figure 18. Thus, the front door plate 31 can be folded up and the user can easily go in and out through the opening formed by folding the front door plate 31.

Next, the movement of each part during the opening operation of the sliding door 3a will be explained.
When the sliding door 3a shown in FIGS. 1, 3 to 5 completely closes the opening 11 and drives the motor to slide the sliding portion 42 away from the opening 11, the rear door plate 32 The sliding door 3a is pulled in the direction of opening the opening 11 while rotating so that the end thereof moves away from the vertical door stop 17.
Then, as the slide portion 42 further slides, the lock head 82 is exposed to the outside of the cavity 74 through the notch hole 71, and the lock is released, and the slide door 3a is opened as shown in FIG. Slide until the opening 11 is fully open.

As described above, in this sliding door device 2a, the front door plate 31 has a folding door structure as an auxiliary door structure, so when the sliding door 3a completely closes the opening 11, the sliding door It is possible to easily go in and out of the garage 1 without sliding the entire part 3a in the opening direction.

Moreover, as described above, in this sliding door device 2a, when the rear door plate 32 comes to the position where the opening 11 is in the closed state, the first engaging portion 7a and the second engaging portion 8a engage with each other. Therefore, even if a large wind pressure is applied to the sliding door, the lower end of the rear door plate 32 can be prevented from being bent to such a degree that it cannot be elastically restored.
Further, the engagement and disengagement between the first engagement part 7a and the second engagement part 8a are performed only by the operation of the rear door plate 32 of the sliding door 3a by the door driving means 4, and a separate locking device is provided. There's no need.

Moreover, the first engagement portion 7a and the second engagement portion 8a can be achieved by only slightly modifying a conventional sliding door device, so the number of parts does not increase significantly, the assembly work is not complicated, and there is no need to incur significant costs.
