The first set and the second set are different only in a transition guide groove 20a (20b) formed in a slide plate 20 as guide means to be described later, and have substantially the same other configuration. The configuration of the means 4 will be described below.

The upper edge of the transparent door A1 is long in the frontage direction (left-right direction), and has an H-shaped upper edge member 10 and packing 1
1 and a bolt-shaped suspending body 13 is erected on the upper edge member 10 via a horizontal pin 12. The upper part of the suspension support 13 is fixed to the front-rear sliding support block 14 by screwing or the like. The front / rear sliding support block 14 can slide back and forth through a pair of left and right sliding support shafts 16 and 16 at a substantially right and left center portion of a support frame 15 having an open lower surface via a slide bearing or a circulator. , So that the transparent door A1 can be moved horizontally in the front-rear direction (the direction in which the transparent door A1 comes into contact with or separates from the opening of the frontage) along the thickness direction thereof.

At the upper end of the support frame 15, a plurality of vertical rolling rollers 17 and a plurality of horizontal rolling rollers 18 are mounted.
These vertical rolling rollers 17 are formed into a first U-shaped cross section.
By rolling on the lower plate of the upper rail 2, the transparent door A
1 is supported so as to be able to move left and right in parallel with the opening of the frontage of the case body 1, and the horizontal rolling rollers 18 roll on the front and rear inner surfaces of the first upper rail 2 to swing in the front and rear directions above the transparent door A <b> 1. Has been prevented.

In the embodiment shown in FIG. 3, the upper part of one transparent door A1 (A2) is connected to the two support frames 15,15.
1 to 4 supporting frames 1 depending on the size of the frontal direction of the transparent door.
5, it is possible to support. A sliding plate 20 as a guide means (guide) for guiding the suspension support 13 and thus the longitudinal slide support block 14 in the longitudinal direction.
Are disposed between the inner surfaces of the front and rear walls of each of the support frames 15 below the front and rear sliding support blocks 14. Sliding plate 20
The guide roller 21 mounted on the sliding plate is sandwiched between a pair of horizontally long upper and lower guide rails 19, 19 fixed to the inner surfaces of the front and rear walls of the support frame 15, and is slidably contacted so as not to fall off and to be movable left and right. 20 makes it possible to smoothly move laterally and to prevent meandering.

The hanging support 13 and the slide plate 20 as a guide are connected to each other through a transition guide groove described later.
When the sliding plate 20 moves by a predetermined distance in the left-right direction, the suspension support 13 is associated so as to be forcibly moved by a predetermined distance in the front-rear direction. That is, as shown by the solid line in FIG. 6, a transition guide groove 20a is formed in the sliding plate 20 so as to be shifted at the left and right ends in the front-rear direction by the small distance S1. The groove 20a is configured such that a middle part in the vertical direction of the hanging support 13 penetrates.

FIG. 5 shows the upper support means 4 for the second set of transparent doors B1 and B2. The support position of the support frame 15 with respect to the second upper rail 3 is different from that of the support frame 15 with respect to the first upper rail 2. The position is slightly different from the suspension position, and the displacement amount of the transition guide groove 20b formed in the slide plate 20 is set to a large distance S2 as shown by a two-dot chain line in FIG. Other configurations are substantially the same as those for the first set of transparent doors, and thus the same components are denoted by the same reference numerals and detailed description thereof will be omitted.

Next, with reference to FIGS. 4 to 8, the closing positions of the transparent doors A1, A2, B1, and B2 (the openings of the case body 1 are flush with all the transparent doors). A position restricting means 24 for positioning and stopping the support frame 15 as the upper supporting means at a position (closed so as to be in close contact with the seal packing 9); Move each transparent door from the reference plane K to the distance S
The sliding plate 20 as the guiding means (guiding body) is opened to the front of the case body 1 by only 1 and S2.
The drive means 25 for forcibly moving the front and rear sides of the frontage is described.

When a plurality of support frames 15 are used, one slide plate 20 is forcibly moved by connecting the slide plates 20 of the adjacent support frames 15 with a horizontally long connecting member 26. Thus, the sliding plates 20 in all the support frames 15 can be forcibly driven at the same time, and the configuration can be simplified. First, as shown in FIG. 6 and FIG. 8, a fitting body 27 having a fitting groove 27 a that opens so as to expand in the depth direction of the case body is formed on the upper surface of one support frame 15 for each transparent door. Is fixed.

On the other hand, as shown in FIGS. 6 to 8, the position restricting means 24 is fixed behind the one support frame 15 at the closed position of each of the transparent doors (on the rear side of the upper rails 2, 3). A moving block 29 provided on the frame 28 so as to be movable back and forth.
And a positioning motor 30 which can be fitted into the fitting groove 27a and which can be fitted in the fitting groove 27a, and a forward / reverse rotatable driving motor 31 as a driving actuator of the moving block 29. More specifically, a pair of left and right sliding shafts 33 provided at the upper end of the moving block 29 are suspended on the supporting block 32 fixed to the lower surface of the fixed frame 28 so as to be able to slide back and forth. The pinion 35 meshing with the rack 34 is driven by a drive motor 31 provided on the lower surface of the fixed frame 28.

In this case, the sliding shaft 33 and the moving block 29
It is preferable to interpose a slide bearing or a circulator for reducing the sliding resistance between the bearings. With these configurations, when the disc-shaped positioning engagement body 30 made of a roller bearing or the like advances in the thickness direction of the transparent door and fits in the fitting body groove 27a (see the two-dot chain line in FIG. 8), the support frame 1 is formed.
5 can be prevented from moving left and right and can be positioned at the closed position. When the positioning engagement body 30 retreats and separates from the fitting body 27 (see the solid line state in FIG. 8), the support frame 15
Eventually, each transparent door can be moved along the upper rails 2 and 3.

The drive means 25 includes a chain 41 wound around chain sprockets 39 and 40 attached to a drive longitudinal axis 37 and a driven longitudinal axis 38 disposed on the lower surface of the fixed frame 28 on the left and right, respectively. A pressing piece 45 fixed to the chain 41 is composed of a worm wheel 44 engaged with a worm 43 driven by a forward / reverse rotatable drive motor 42 fixed to the lower surface and attached to the drive longitudinal axis 37.
Presses the pressed piece 46 protruding from the rear side of the sliding plate 20 to the right or left to realize the forced movement of the sliding plate 20 to the left or right.

That is, in the solid line state in FIG. 6, the chain 41 rotates counterclockwise and the pressing piece 45 is
The sliding plate 20 is pushed right through the

The suspension support 13 and thus the transparent door A1 (A2) are
(Seal packing 9) is pushed and opened by a distance S1 in a direction away from (seal packing 9).

In the case of the second set of transparent doors B1 and B2, the amount of displacement in the front-rear direction at the right end and the left end of the transition guide groove 20b while moving the sliding plate 20 left and right by the same amount as described above. Is the distance S2. As shown in FIG. 6, when the home position sensor 80 disposed on the rear side of the winding of the chain 41 detects the pressing piece 45 located on the front side thereof, the home position for stopping the rotation of the chain 41 is detected. Becomes The auxiliary piece 81 fixed to the opposite side of the pressing piece 45 to the chain 41 is attached to the first sensor 8.
2, the sliding plate 20 moves to the right and detects that the suspension support 13 is located at the left end of the transition guide groove 20a (the position where the transparent door is in close contact with the seal packing 9). When the second sensor 83 senses the auxiliary piece 81, the slide plate 20 moves to the left to move the transition guide groove 2
The hanging support 13 is located at the right end of Oa, and the open state of the transparent door can be detected.

Next, the structure for supporting and moving the lower ends of the transparent doors A1, A2, B1, B2 will be described. FIG. 9 is a side sectional view of a mechanism of the first lower supporting means 5 for supporting the lower ends of the first set of transparent doors A1 and A2, respectively. FIG. 10 is a sectional view of the lower end of the second set of transparent doors B1 and B2.
