DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0015]
As shown in FIG. 1, the all-round shielding door device 1 according to the embodiment of the present invention includes a door main body portion 2 that shields openings such as a passage, a window, and an entrance, and the above-described portions shown in FIGS. 3 and 4. Grooves 21, 23, 25, 27 formed on the periphery of the opening, and are housed in the respective sides of the door main body 2, and project from and into the grooves 21, 23, 25, 27, It is at least comprised by the shielding plates 3, 4, 5, and 6 which close the clearance gap between the said opening part periphery and the said door main-body part 2 periphery.
[0016]
Further, as shown in FIG. 1, the shielding plates 3, 4, 5, 6 are respectively in the state where the shielding plates 3, 4, 5, 6 are immersed in the door body 2. , 5 and 6 are formed so as to overlap each other. Specifically, the end of one shield plate overlaps with the end of the other shield plate so that the length of the side increases as the shield plates 3, 4, 5, and 6 protrude. It comes to correspond to.
[0017]
Further, the respective shielding plates 3, 4, 5, 6 are connected to each other by a crank plate 7. In this embodiment, the crank plate 7 includes a first coupling portion 7a fixed to one shielding plate, a second coupling portion 7b fixed to the other neighboring shielding plate, and the door main body portion. The rotation fulcrum part 7c fixed to 2 is arranged so as to form an isosceles triangle having the rotation fulcrum part 7c as a vertex. Thereby, the protrusion amount of each shielding plate 3, 4, 5, 6 can be made the same. Moreover, when the protrusion amount of an adjacent shielding plate is changed, it can respond by changing the distance from the rotation fulcrum part 7c. In this case, the triangle is not an isosceles triangle.
[0018]
As a result, as shown in FIG. 3, when one of the shielding plates 3, 4, 5 and 6 is made to project and retract with respect to the door body 2, the crank plates 3 rotate simultaneously, so that the remaining shielding plates Also, the door body 2 can be moved in and out in synchronization with the operated shielding plate.
[0019]
Thereby, as shown in FIGS. 3 and 4, when the all-round shielding door device 1 is opened (FIGS. 3A and 4A), the shielding plates 3, 4, 5, and 6 are Since the door main body 2 is immersed, the door main body 2 is movable (openable and closable). Further, when the all-round shielding door device 1 is closed (FIGS. 3B and 4B), the shielding plates 3, 4, 5, and 6 project from the door body 2 and each peripheral wall portion. Since it engages with the grooves 21, 23, 25, 27 formed in 20, 22, 24, 26, the entire opening is shielded and the front and rear of the door can be completely blocked. In FIG. 4, reference numerals 28 and 29 denote pivot hinges that serve as pivot points for the door main body 2.
[0020]
Further, as shown in FIGS. 5 (a), (b), (c), and (d), the all-round shielding door device 1 of the present invention appears and disappears in response to the appearance and depression of the lower shielding plate 6, An adjuster 8 that is movable in the vertical direction is provided. The adjuster 8 is composed of two parts having overlapping portions with a predetermined length in the side direction so that the length in the side direction can be adjusted. Further, the adjuster 8 is configured to adjust the length in the side direction and the vertical cam holes 81, 82, 83 formed so as to be movable in the vertical direction with respect to the lower shielding plate 6. The cam holes 81, 82, 83, 87, 88 are fitted with pins 84, 85, 86, 89 protruding from the lower shielding plate 6.
[0021]
Accordingly, when the obstacle 30 is on the lower peripheral wall portion (floor portion) 26, the height of the obstacle 30 is absorbed by the adjuster 8, and the operation of the lower shielding plate 6 is not hindered. This does not obstruct the protruding operation of the plates 3, 4, 5.
[0022]
Further, as shown in FIG. 6, the all-round shielding door device 1 is provided with a lever handle 9 for projecting and immersing the shielding plates 3, 4, 5 and 6. The lever handle 9 moves the operating fulcrum 9a fixed to the shielding plate 3 so as to be rotatable, with the rotating fulcrum 9b serving as a fulcrum, and causes the shielding plate 3 to appear and retract. Thus, the shielding plates 4, 5, 6 connected via the shielding plate 3 and the crank plate 7 are interlocked. Further, a return spring may be provided at the rotation fulcrum 9b.
[0023]
Further, a spring 10 is provided between the shielding plate 3 and the door main body 2 as a biasing means for biasing the shielding plate 3 in a direction protruding from the door main body 2 and is automatically activated by releasing the lock mechanism described below. Thus, the shielding plates 3, 4, 5, 6 can be protruded.
[0024]
Further, the all-round shielding door device 1 of the present invention is provided with a lock device 11. The locking device 11 uses a normal cylinder lock. When the lock 11 of the cylinder lock 11 is engaged, the dead bolt 11a protrudes and prevents the shielding plate 3 from being immersed. 5 and 6 are held at the protruding positions and remain engaged with the grooves 21, 23, 25, 27, and the all-round shielding door device 1 is locked. Further, when the lock device 11 is unlocked, the shielding plate 3 can be freely immersed, and the lever handle 9 can be opened and closed.
[0025]
Further, as shown in FIG. 7, the lock mechanism is provided in the shielding plate 4, and the rod rod 41 protrudes into the lock hole 40 opened in the outer frame of the door main body 2 with the immersion of the shielding plate 4. In order to do this, the shielding plates 3, 4, 5, 6 are held in the immersed position. The lock mechanism release device 50 includes a release rod 51 that is provided on the upper peripheral wall portion 25 and protrudes to a position corresponding to the lock hole 40. Accordingly, when the all-round shielding door device 1 has moved to the closed position, the release rod 51 is inserted into the lock hole 40 and the rod rod 41 is pushed into the shield plate 4, so that the lock is released. The shielding plates 3, 4, 5 and 6 can automatically protrude.
