That is, in FIG. 3A, the door body 4 pulled out to the left side of the door pocket 3 is driven by another drive mechanism (not shown) and moves back and forth with respect to the door pocket 3.

(Panel support structure)
Next, with reference to FIG. 4, a structure for supporting the panel 7 of the door pocket 3 will be described. Note that FIG. 4 is an arrow view of the movable platform fence 1 as viewed from the direction indicated by the arrow C in FIG. 3 (B). Further, FIG. 4 shows a state in which the panel covering the end surface of the door pocket 3 on the side where the door body 4 moves forward and backward, that is, the panel that can be seen in the front when the door pocket 3 is viewed from the direction indicated by the arrow C is removed.

As shown in FIG. 4, a support frame 20 for supporting the panel 7 is fixed to the upper part of the door pocket 3. A metal protective frame 21 is fitted on the upper edge of the panel 7. The protective frame 21 is fitted in the support frame 20. Further, since there is a gap between the support frame 20 and the protective frame 21, the movement of the panel 7 in the direction perpendicular to the paper surface is not restricted by the support frame 20. That is, the movement of the panel 7 in the direction in which the door body 4 moves forward and backward is not restricted by the support frame 20. Further, since there is a gap between the support frame 20 and the protection frame 21 in the vertical direction as well, the panel 7 can be moved upward. That is, the panel 7 can be lifted upward. Although not shown, the support frame 20 is also fixed to the lower part of the door pocket 3. The lower edge of the panel 7 is in contact with a support frame 20 (not shown) fixed to the lower part of the door pocket 3, and the weight of the panel 7 is mainly supported by a support frame 20 (not shown) fixed to the lower part of the door pocket 3. ..

Further, as shown in FIG. 4, the protective frame 21 includes a fixing portion 21a that sandwiches the panel 7 and is fixed to the panel 7, and a receiving portion 21b that has an inverted “L” shape in cross section.

(Panel lifting jig)
The configuration of the panel lifting jig 22 used in the method of removing the panel 7 described later will be described with reference to FIG. 5 (A) is a perspective view of the panel lifting jig 22, and FIG. 5 (B) is an arrow view of the panel lifting jig 22 as viewed from the direction indicated by the arrow E in FIG. 5 (A).

As shown in FIGS. 5A and 5B, the panel lifting jig 22 includes a base portion 22a into which the upper end of the door body 4 is fitted and a support portion 22b for supporting the door body 4, and has side surfaces. It has an "h" shape in shape. Further, a plurality of lifting screws 22c are screwed into the base portion 22a of the panel lifting jig 22. When the lifting screw 22c is rotated, the lifting screw 22c advances and retreats with respect to the base portion 22a.

(How to remove the panel)
Next, with reference to FIGS. 6 and 7, a procedure for removing the panel 7 from the door pocket 3 using the panel lifting jig 22 will be described in chronological order. When removing the panel 7 from the door body 4, first, as shown in FIG. 6A, the door body 4 is pulled out of the door pocket 3. Next, as shown in FIG. 6B, the panel lifting jig 22 is attached to the upper side of the door body 4. After that, as shown in FIG. 6C, the door body 4 to which the panel lifting jig 22 is attached is pulled into the door pocket 3. As shown in FIG. 7A, a coproduct for accommodating the door body 4 to which the panel lifting jig 22 is attached is formed inside the door pocket 3, and the door to which the panel lifting jig 22 is attached is formed. When the body 4 is pulled into the door pocket 3, the support portion 22b of the panel lifting jig 22 is inserted into the gap between the panel 7 and the protective frame 21.

An opening 3a is formed in a portion of the upper surface of the door pocket 3 located directly above the lifting screw 22c of the panel lifting jig 22, and as shown in FIG. 7B, the tool 23 is inserted into the door pocket 3 from the opening 3a. It can be inserted into and engaged with the lifting screw 22c. When the tool 23 is rotated to rotate the lifting screw 22c, the lifting screw 22c can be moved forward and backward with respect to the base portion 22a. When the lifting screw 22c is moved below the base 22a, the tip of the lifting screw 22c is brought into contact with the upper end surface 4a of the door body 4, and the lifting screw 22c is further moved below the base 22a, the panel lifting jig 22 is pushed up by the lifting screw 22c and rises with respect to the door body 4. The height h of the support portion 22b of the panel lifting jig 22 (see FIG. 5B) is larger than the depth d of the receiving portion 21b of the protective frame 21 (see FIG. 4). Therefore, when the panel lifting jig 22 is further raised, the upper end of the support portion 22b of the panel lifting jig 22 comes into contact with the lower surface of the upper end of the receiving portion 21b of the protective frame 21. As described above, since there is a vertical gap between the protective frame 21 of the panel 7 and the support frame 20 of the door pocket 3, when the tool 23 is further rotated and the panel lifting jig 22 is further raised, The protective frame 21 and the panel 7 are lifted upward by the panel lifting jig 22. In this way, the support portion 22b of the panel lifting jig 22 abuts on the receiving portion 21b of the protective frame 21 to support the panel 7 and lift the panel 7 upward. The receiving portion 21b of the protective frame 21 functions as a jig receiving member of the panel 7. Further, the lifting screw 22c functions as a lifting means for raising and lowering the support portion 22b of the panel lifting jig 22 with respect to the door body 4.

In the state shown in FIG. 7A, the height of the support portion 22b of the panel lifting jig 22 and the lifting stroke of the lifting screw 22c are such that the support portion 22b of the panel lifting jig 22 is the receiving portion of the protective frame 21. At a position separated from 21b, in the state shown in FIG. 7B, the support portion 22b is in contact with the receiving portion 21b, and the panel lifting jig 22 is designed so that the panel can be lifted.

In this way, the panel 7 is lifted upward by the panel lifting jig 22 and supported by the door body 4. Then, when the door body 4 is pulled out of the door pocket 3 in this state, the panel 7 moves to the outside of the door pocket 3 together with the door body 4, as shown in FIG. 7 (C). As a result, the front surface of the door pocket 3 is opened, and access to the drive mechanism arranged inside the door pocket 3 becomes possible. The panel 7 is removed from the door pocket 3 through the above process. When attaching the panel 7 to the door pocket 3, the reverse of the above process is followed.

(Modification example of panel lifting jig)
The panel lifting jig 22 may be configured as shown in FIG. 8 (A). That is, a plurality of rollers 22d may be rotatably attached to the support portion 22b of the panel lifting jig 22 so that the door body 4 is supported by the rollers 22d. If the panel lifting jig 22 is provided with the roller 22d in this way, the roller 22d rolls in a state where the roller 22d is in contact with the door body 4, so that the door body supported by the panel lifting jig 22 rolls. 4 can be easily slid on the panel lifting jig 22. Therefore, as shown in FIG. 8B, the panel 7 pulled out to the outside of the door pocket 3 is further moved to the outside of the door pocket 3 together with the door body 4, and the front surface of the door pocket 3 is opened more widely. Can be done. Further, as shown in FIG. 8B, the panel lifting jig 22 has dimensions such that when it is attached to the door body 4, it overhangs the outside of the door body 4 (to the right in the figure). You may have. In this way, when the door body 4 is slid on the panel lifting jig 22, the door body 4 is held by the panel lifting jig 22 in its entire width. Therefore, the door body 4 is stably held by the panel lifting jig 22.

(Another modification of the panel lifting jig)
The panel lifting jig 22 is not limited to the one in which the base portion 22a is fixed to the upper side of the door body 4. Further, the panel lifting jig 22 is not limited to the one in which the entire panel lifting jig 22 moves up and down with respect to the door body 4. As shown in FIGS. 9A and 9B, the base portion 22a of the panel lifting jig 22 may be fixed to the side surface of the door body 4 with the fixing screws 22e. Further, the panel lifting jig 22 is not limited to the one in which the entire panel lifting jig 22 moves up and down with respect to the door body 4. As shown in FIGS. 9A and 9B, the lifting screw 22f has a left-hand screw 22l formed at a portion screwed with the base portion 22a and a right-hand screw 22r formed at a portion screwed with the support portion 22b. The base portion 22a and the support portion 22b may be connected to each other. With this configuration, the distance in the height direction between the base portion 22a and the support portion 22b can be changed by rotating the elevating screw 22f. Therefore, the support portion 22b can be moved up and down with respect to the door body 4 between the position shown in FIG. 9A and the position shown in FIG. 9B.

(Modified example of protective frame)
The protective frame 21 may be configured as shown in FIG. 10 (A). That is, the protective frame 21 may be provided with a plurality of pins 21c on the side surface of the fixing portion 21a instead of being provided with the receiving portion 21b. As shown in FIG. 10B, the pin 21c includes a pin body 21d and a flange 21e. The pin body 21d is a portion where the support portion 22b of the panel lifting jig 22 abuts, and the flange 21e is a portion that functions as a stopper for the support portion 22b to come off.

(Modified example of drive mechanism arrangement)
The drive mechanism for moving the door body 4 forward and backward with respect to the door pocket 3 may be arranged as shown in FIG. That is, an opening 14o that penetrates the support column 14L may be formed in the support column 14L, and a part of the rack storage body 16 may be arranged so as to be exposed on the left side of the support column 14L through the opening 14o. In this way, the operating stroke of the drive mechanism can be expanded. In other words, the width of the door body 4 can be increased.

(Detailed composition of movable home fence)
(Connecting member)
Finally, the detailed configuration of the movable platform fence 1 will be described. First, a specific configuration of the connecting member 18 will be described. As shown in FIG. 12A, the connecting member 18 includes a main body member 18a fixed to the door body 4, a sliding member 18b slidably supported by the rack guide body 15, and a sliding member 18b. A fixing screw 18c for fixing to the main body member 18a is provided. Further, the main body member 18a is formed with three engagement holes 18d that engage with the teeth 17a of the flexible rack 17. The flexible rack 17 is connected to the main body member 18a by engaging the teeth 17a with the engaging holes 18d.

FIG. 12B is a front view showing a state in which the connecting member 18 and the flexible rack 17 are connected and fixed to the door body 4. As shown in FIG. 12B, both the flexible rack 17 and the sliding member 18b are slidably supported by the rack guide 15 and slid freely in the directions indicated by the arrows ± X. Since the main body member 18a is fixed to the sliding member 18b by the fixing screw 18c, the main body member 18a moves back and forth with respect to the door pocket 3 (not shown in FIG. 12B). It does not displace with respect to the flexible rack 17. That is, the main body member 18a does not move up and down or tilt with respect to the flexible rack 17. Therefore, the teeth 17a of the flexible rack 17 do not come off from the engaging holes 18d of the main body member 18a. That is, the flexible rack 17 does not come off from the connecting member 18 in the process of moving the door body 4 back and forth with respect to the door pocket 3.

Further, since the connecting member 18 engages the teeth 17a of the flexible rack 17 with the engaging holes 18d, it is not necessary to process the portion to be connected to the main body member 18a of the flexible rack 17. That is, it is not necessary to make a hole in the flexible rack 17 or cut out a part thereof. Therefore, stress is not concentrated on a specific portion of the hole or notch, and the flexible rack 17 is not damaged.

(Food)
FIG. 13 is a cross-sectional view showing the movable platform fence 1 cut along the plane shown by the AA'line in FIG. 2 (B). As shown in FIG. 13, a cushion member 8a is attached to a portion of the tip of the hood 8 that covers the upper part of the panel 7 when the hood 8 is closed. When the hood 8 is closed, the cushion member 8a comes into contact with the upper part of the panel 7 and presses the panel 7. As a result, since the panel 7 is pressed against the frame 3b of the door pocket 3, rattling due to the gap between the support frame 20 of the door pocket 3 and the protective frame 21 of the panel 7 does not occur.

As shown in FIG. 14A, the hood 8 is attached to the door pocket 3 via a hinge 24. As shown in FIG. 14B, the hood 8 may be attached to the door pocket 3 via the torque hinge 24'instead of the hinge 24. The torque hinge 24'is a hinge provided with a spring element, and can generate torque in the direction of lifting the hood 8. Therefore, the hood 8 can be opened with a small force. Further, the torque generated by the torque hinge 24'acts in a direction that prevents the hood 8 from falling.
