Description

  The present invention relates to a technical field of a watertight device for a tide plate for watertightness between a tide plate and a casing.

In general, some of the building opening and closing devices installed in the housing opening are configured so that the opening is opened and closed by moving up and down guided by guide rails arranged on the left and right of the opening. However, in such a switchgear for a building, conventionally, as a measure to prevent outside water from entering the indoors in the case of heavy rain floods, etc., a technology provided with a tide plate at the bottom of the switchgear Is known (see, for example, Patent Document 1). In this structure, the tide plate can be installed in the opening by lowering the opening / closing body, and a member and labor for separately installing the tide plate in the opening can be omitted.
By the way, when the tide plate is installed in the lower part of the opening and closing body as described above, when there is a possibility of intrusion such as heavy rain flood, the opening and closing body is lowered and the lower part of the opening is closed with the tide board and the flooding is surely prevented. In order to achieve this, it is required to ensure water tightness between the tide plate and the frame. Therefore, in the thing of patent document 1, while setting the base end part of the press tool which can adjust length to a tide board, it is set as the structure which fixes and supports the front-end | tip part of this press tool on a floor surface detachably, By adjusting the length of the tide plate in a watertight manner against the inner wall surface of the guide rail, water tightness between the left and right ends of the tide plate and the guide rail fixed to the housing is ensured. In this case, a watertight material is provided on the bottom surface of the tide plate, and the watertight material is brought into contact with the floor surface by the weight of the tide plate, thereby ensuring watertightness between the tide plate and the floor surface. .
On the other hand, instead of providing a tide plate at the bottom of the opening and closing body, a tide plate is inserted into the grooves of the opposed grooved vertical columns arranged on the left and right sides of the opening when a heavy rain flood or the like is predicted (for example, However, in such a tide plate as well, the watertightness between the tide plate and the casing is ensured. In the case of Patent Document 2, the bottom of the tide plate and A water-tight material (elastic waterproofing rubber) is provided in front of the left and right ends, and the water-tight material is pressed against the floor surface and the groove inner surface of the upright column by turning the crescent.

However, in the case of a storm flood, the water that is going to enter indoors because it is between the lower end of the tide plate and the floor surface acts as a force to float the tide plate. There is a possibility that the infiltration cannot be reliably prevented by simply bringing the watertight material provided into contact with the floor surface by the weight of the tide plate.
On the other hand, in the case of Patent Document 2, the tide plate is prevented from rising by the crescent over the tide plate and the upright, but in this case, the tide plate is moved to the housing side (floor) based on the turning operation of the crescent. The water-tight material is compressed by bringing it close to the surface and the inner surface of the vertical pillar groove) to achieve water-tightness between the tide plate and the enclosure, and when the tide plate is brought closest to the enclosure side, the tide plate and enclosure It is set so that a predetermined interval exists with the side, and the predetermined interval is a space for interposing a compressed watertight material. However, the tide plate is not used for a long time because it is used in the event of an emergency such as a storm flood. On the other hand, the watertight material formed from elastic rubber or the like deteriorates little by little for a long time. There is a possibility that the restoring force may be reduced, but if the elastic restoring force of the watertight material has declined, the initial value is set even if the watertight material is compressed by bringing the tide plate close to the housing side. There is a possibility that the function as a watertight material cannot be sufficiently exhibited by the compression up to a predetermined interval, and there is a problem to be solved by the present invention.

It is like that.

  On the other hand, the insertion hole 27 recessed in the floor surface G is formed in a box shape having an upper surface portion 27a, and the insertion hole upper surface portion 27a is positioned coaxially with the operating body 23, In addition, a through hole 27b having a slightly larger diameter than the operating body 23 and a pair of through groove portions 27c extending from the through hole 27b to the outer diameter side are formed. The through-groove 27c is formed in a state of being aligned with the locking piece 23a at the unlocking position so that the locking piece 23a at the unlocking position can enter and exit, and thus the locking piece 23a. In the state where the locking piece 23a is positioned at the unlocking position, the locking piece 23a is allowed to enter and exit from the insertion hole 27. On the other hand, when the locking piece 23a is positioned at the locking position, between the pair of through-groove portions 27c. The engaging piece 23a abuts on the outer peripheral portion 27d of the through hole so that the entering and exiting of the engaging piece 23a into the fitting hole 27 is restricted (see FIG. 5). In addition, although the through-hole outer peripheral part 27d between a pair of through-groove parts 27c is corresponded to the latching receiving part provided in the insertion hole of this invention, after that, the through-hole outer peripheral part 27d between a pair of through-groove parts 27c is referred to. These are simply referred to as the through hole outer peripheral portion 27d or the latch receiving portion 27d. Further, the latch receiving portion 27d and the latch piece 23a provided on the operating body 23 constitute the lock mechanism 26 of the present invention.

  Then, in a state where the operation lever 24a is rotated and the locking piece 23a is set to the unlocked position, the operation body 24 is depressed by stepping on the upper surface of the operation unit 24 with a foot or pushing it down with a hand. The lower surface of the large-diameter operation portion 24 is brought into contact with the upper support piece 22a of the support bracket 22 and can be moved downward to a lower movement position where further downward movement is restricted. The locking piece 23a is set so as to be fitted into the fitting hole 27 through the through groove portion 27c in a state where the operating body 23 is moved down to the moving position.

  Further, the pressing spring 25 includes an upper spring receiver 25a fixed to the operating body 23 between the upper support piece 22a and the lower support piece 22b, and a lower spring receiver provided on the upper surface portion of the lower support piece 22b. 25b. The pressing spring 25 is configured so as to be stored when the operating body 23 is moved downward by pushing down the operation portion 24 and presses the tide plate 7 downward via the lower support piece 22b. Has been.

  Here, a procedure for pressing the tide plate 7 against the floor G in a watertight manner based on the operation of the operation unit 24 and the operation lever 24a will be described with reference to FIGS. First, in a state where there is no fear of flooding such as a storm flood, the operation unit 24 is not pushed down and the operation lever 24a is set to the locked position. In a state where the operation lever 24a is located at the lock position, the operation lever 24a is parallel to the indoor side surface of the tide plate 7 and hardly protrudes to the indoor side. The locking piece 23a provided in the portion is also located at the lock position. Further, in a state where the operation portion 24 is not pushed down, the pressing spring 25 is in a free state or a state where the operating body 24 is slightly stored, and the operating body 23 is fixed to the operating body 23 by the pressing spring 25. The upper spring receiver 25a is positioned at the upper movement position where it contacts the upper support piece 22a of the support bracket 22 from the lower side, and the lower end portion of the operating body 23 at the upper movement position is positioned above the fitting hole upper surface portion 27a. In addition, the locking piece 23a at the locked position is set so as not to interfere with the insertion hole upper surface portion 27a (see FIGS. 3A and 3B).

  On the other hand, when there is a risk of inundation such as a storm flood, the operation lever 24a is first swung to the unlock position. As the operating lever 24a is moved to the unlocking position, the locking piece 23a is also displaced to the unlocking position where it is aligned with the through groove 27c of the upper surface portion 27a of the insertion hole (FIG. 3C, ( D)).

  Further, with the operation lever 24a in the unlocked position, the operation unit 24 is pushed down from above, and the operating body 23 is moved until the lower surface of the operation unit 24 comes into contact with the upper support piece 22a of the support bracket 22. Move down. As a result, the pressing spring 25 is stored, and the locking piece 23a at the lock position passes through the through groove portion 27c of the fitting hole upper surface portion 27a and fits into the fitting hole 27 (FIGS. 4A and 4B). reference).

  Next, the operation lever 24a is swung to the lock position while the operation unit 24 is being pushed down. As the operating lever 24a is set to the locked position, the locking piece 23a is also displaced to the locked position. Thereafter, when the foot is removed from the operation portion 24, the operating body 23 tends to move upward by the stored force of the pressing spring 25, but the locking piece 23a at the lock position is the outer peripheral portion 27d of the through hole of the insertion hole upper surface portion 27a. The upward movement of the actuating body 23 is restricted by being locked from below, so that the actuating body 23 is locked at the downward movement position where the locking piece 23 a at the lower end of the actuating body 23 is fitted into the fitting hole 27. Is done. The stored force of the pressing spring 25 when the operating body 23 is locked in the downward movement position acts as a force for pressing the tide plate 7 downward via the lower support piece 22b of the support bracket 22, As a result, the tide plate-side watertight material 20 provided at the lower end of the tide plate 7 is pressed in a water-tight manner by the floor-side watertight material 21 provided on the floor surface G, so that the tide plate 7 and the floor surface G are pressed. Is configured to be watertight (see FIGS. 4C and 4D).

  When the fear of inundation such as a storm flood is released, the operating body 23 locked at the lower movement position is returned to the upper movement position. In this case, the operation lever at the lock position is returned. When 24a is swung to the unlocking position, the locking piece 23a is also displaced to the unlocking position and the escape from the insertion hole 27 is allowed. In this state, the stored force of the pressing spring 25 acts as a force for moving the operating body 23 upward via the upper spring receiver 25a, and the operating body 23 automatically moves up to the upward movement position. Thereafter, the operation lever 24a is swung to the lock position to return to the initial state where the watertight device 19 is not operated.

  Here, when returning the operating body 23 locked in the lower movement position to the upper movement position, as described above, the locking piece 23a is displaced from the lock position to the lock release position based on the operation of the operation lever 24a. However, in this case, the locking piece 23a is displaced while being in contact with the through hole outer peripheral portion 27d of the insertion hole upper surface portion 27a from the lower side, and therefore, the locking piece 23a and the through hole outer peripheral portion 27d. When the contact area is large, it becomes a resistance when the operation lever 24a is swung. Therefore, in the present embodiment, the upper portion of the locking piece 23a is formed in an inclined shape so that the protrusion amount in the outer diameter direction becomes smaller toward the upper end portion, and the locking piece 23a and the through hole outer peripheral portion 27d are formed. The contact area is made as small as possible, so that the operating force of the operating lever 24a when the locking piece 23a at the locked position is displaced to the unlocked position is taken into consideration.

The locking piece 23a inserted into the insertion hole 27 is locked with the locking receiving portion 27d and the locking receiving portion when the operating body 23 is rotated by the swinging operation of the operation lever 24a. It will be displaced to the unlocking position that is not locked to 27d. As a result, the lock mechanism 26 for locking the operating body 23 in the downward movement position can be easily locked and unlocked by swinging the operation lever 23, so that the operating body 23 can be quickly moved even in an emergency. It can be locked in the down position.

  In addition, the operation unit 24 for lowering the operating body 23 is provided on the upper side of the operating body 23 and is configured to move the operating body 23 downward by depressing the operating unit 24. Even if the downward movement operation of 23 is an operation that accompanies the accumulation of the pressing spring 25, the actuating body 23 can be easily moved downward by the push-down operation.

  Further, the overhead door 1 with the tide function includes a second watertight device 30 for watertightness between the left and right ends of the tide plate 7 and the housing. The guide member 31 is fixed to the side, and has a facing surface portion 32b facing the indoor side surfaces of the left and right ends of the tide plate 7, and the guide surface 31b is detachable from the tide plate 7. A second working body 32 supported by the member 31, a second watertight member 33 provided on the facing surface portion 32 b of the second working body 32, and the second watertight member 33 are pressed against the tide plate 7 in a watertight manner. A second operating portion (a cam 34 and a second operating lever 35) operated to bring the second operating body 32 close to the tide plate 7 to the operating position is configured. Thus, by moving the second operating body 32 to the operating position and pressing the second watertight member 33 against the tide plate 7 in a watertight manner, the watertightness between the left and right ends of the tide plate 7 and the housing can be reliably secured. It will be possible. By the way, the hydraulic power that is going to enter from the outside in the case of a storm flood or the like acts as a force that presses the tide plate 7 toward the second watertight material 33 side. For this reason, even if the second watertight member 33 is deteriorated over a long period of time and the elastic restoring force is somewhat reduced, the hydraulic force acts on the tide plate 7 to cause the second watertight member 33 to It can be compressed until it adheres to the tide plate 7 in a watertight manner.

  The second operation unit provided in the second watertight device 30 includes a rotatable cam 34 that acts on the second operating body 32 to move the second operating body 32 away from and in contact with the tide plate 7, The second operating lever 35 is swingably operated to rotate the cam 34. Thus, the second operating body 32 can be easily moved to the operating position by the swinging operation of the second operating lever 35, and the second watertight device 30 can be quickly operated even in an emergency. Can do.

  In the present embodiment, the tide plate 7 is connected to the lowermost panel body 3 via the connection panel 16, and the connection panel 16 is connected to the upper portion of the tide plate 7 via the bolt 17. Yes. Thus, for example, when the watertight device 19 and the second watertight device 30 are operated and the tide plate 7 prevents water from entering the indoor side, it is necessary to escape from the housing opening to the outside. After loosening 17 and removing the tide plate 7 from the connection panel 16, the opening / closing device 8 is driven to move the panel body 3 and the connection panel 16 upward to open the opening above the tide plate 7, from which the outdoor Can escape to.

Needless to say, the present invention is not limited to the above-described embodiment. For example, the locking piece provided on the operating body is provided so as to be able to protrude and retract from the outer peripheral surface portion of the operating body in the outer diameter direction. A spring is provided for biasing the protruding side of the piece, and the locking piece that protrudes in the outer diameter direction as the locking piece is inserted into the locking hole or the insertion hole is opposed to the spring. It is also possible to provide a guide portion (for example, an inclined surface formed at the lower end portion of the locking piece of the above-described embodiment) that guides so as to be immersed. When configured in this manner, even if the locking piece is positioned at the lock position, the locking piece can be fitted into the fitting hole, and the latching piece fitted into the fitting hole has a biasing force of the spring. Thus, it automatically protrudes in the outer diameter direction of the operating body and is locked to the locking receiving portion of the insertion hole. Thus, in this case, the lock mechanism is automatically operated in accordance with the lowering of the operating body, and the operating body is locked in the downward movement position, and there is an advantage that the operability is more excellent.
Moreover, in the said embodiment, the water-tight material for water-tightening between a tide board and a frame floor surface is provided in both the lower end part and floor surface of a tide board, and more reliable water-tightness was achieved. However, a watertight material may be provided only on either the lower end of the tide plate or the floor surface.
Furthermore, although the present invention is implemented in an overhead door in the above embodiment, it is needless to say that the present invention can be implemented in various building opening / closing devices that are installed in a housing opening such as a panel shutter.
