  The opening / closing operation member attachment 2 attached to the back surface 1a side of the door body 1 has an opening end member separated from the back surface 1a side of the door body 1 with the base end side as a fulcrum, and is provided on the sluice frame 12 To the receiving piece 4 side, it is attached movably so as to rotate horizontally, for example, horizontally. An opening / closing operation member 3 is attached to the opening / closing operation member mounting tool 2.

  The opening / closing operation member fixture 2 includes a pair of upper and lower plate pieces 21 and 22 arranged in parallel vertically, a connecting plate 23 and a vertical shaft 24 on the base end side, and an operation member bearing movable plate 25 provided on the front end side. Etc. The opening / closing operation member mounting tool 2 is rotated horizontally, for example, horizontally, with the vertical shaft 24 on the proximal side on the back surface 1a side of the door body 1 as a fulcrum.

  The upper plate piece 21 and the lower plate piece 22 of the opening / closing operation member fixture 2 are connected by a connecting plate 23 attached between the upper and lower sides closer to the base end side. An up and down vertical shaft 24 is connected to the base end side which is the front side of the connection board 23. The vertical shaft 24 is connected to the side surface at the tip end side of a connecting shaft 23 a that horizontally penetrates the connecting plate 23. That is, the vertical shaft 24 is connected to the connection board 23 via the connection shaft 23a. For example, a screw rod is used for the connecting shaft 23a, and the distance between them can be adjusted.

  The vertical shaft 24 facing upward and downward is pivotally supported by upper and lower bearing pieces 24a attached to both upper and lower ends thereof so as to be spaced apart from the back surface 1a side of the door body 1 in the vertical direction. The vertical shaft 24 is integrally connected to the connecting plate 23, the upper plate piece 21, the lower plate piece 22, the operating member bearing movable plate 25, and the like through the connecting shaft 23a. The opening / closing operation member fixture 2 is rotated horizontally, for example, horizontally toward the rear on the back surface 1a side of the door body 1 with the vertical shaft 24 on the base end side as a fulcrum.

  The actuating member bearing movable plate 25 is provided on the distal end side of the opening / closing actuating member fixture 2 on the side opposite to the side connected to the vertical shaft 24. The actuating member bearing movable plate 25 is attached between the upper plate piece 21 and the lower plate piece 22 on the distal end side of the opening / closing actuating member fixture 2 so as to be rotatable around the vertical axis. A shaft hole 25a penetrating horizontally, for example, horizontally, is formed in the center of the operating member bearing movable plate 25. The shaft hole 25a is inserted into the opening side of the opening / closing operation member 3 bent in a “hoop shape” and is pivotally supported around the axis of the member.

  The opening / closing operation member 3 is operated when the door body 1 is opened / closed, and has a function of instantaneously fixing the door body 1 so that the closed door body 1 is not opened, and is attached to the opening / closing operation member attachment 2 as described above. ing. The opening / closing operation member 3 has its distal end portion 31 inserted and engaged with the receiving groove 41 of the opening / closing operation member receiving piece 4, and the door body 1 closed with the sluice is connected to the sluice frame 12 through the opening / closing operation member receiving piece 4. Crimp to the side and hold. The opening / closing operation member 3 is disposed on the side of the pair of the upper plate piece 21 and the lower plate piece 22 arranged side by side above and below the opening / closing operation member fixture 2 when not in use.

  The opening / closing operation member 3 is formed of a round bar-shaped member having a circular cross section, and a tip portion 31 engaged with the receiving groove 41 of the opening / closing operation member receiving piece 4 is formed in a rounded shape close to a semi-spherical shape. The round bar-shaped opening / closing operation member 3 is bent in a “hoop shape” so that it can be easily operated. The rear half portion of the opening / closing operation member 3 excluding the bent front end side is a holding portion 32 extending straight, and the operator operates the opening / closing operation member 3 by holding the holding portion 32.

  The opening / closing operation member 3 has a distal end side bent at, for example, an angle of 120 degrees in a “hoop shape”. The bent front end side is attached by inserting a horizontal shaft hole 25a of the operating member bearing movable plate 25 provided on the rotating front end side of the opening / closing operation member fixture 2, for example, It is pivotally supported so as to be rotatable around the axis of the member. The front end side of the opening / closing operation member 3 and the whole of the “open” opening / closing operation member 3 center around the shaft hole 25a of the operation member bearing movable plate 25 around the axis of the member, for example, around the horizontal axis. It rotates forward and reverse at an angle of 90 degrees.

  That is, the distal end side of the opening / closing operation member 3 and the entire “open” -shaped opening / closing operation member 3 are configured to rotate forward and backward between, for example, a horizontal direction and a vertical upward direction. When the opening / closing operation member 3 bent to 90 degrees is rotated 90 degrees and the latter half part thereof is extended upward, the closed door body 1 is held in a locked state without being opened. When the opening / closing operation member 3 is rotated 90 degrees in the reverse direction and the entire opening / closing operation member 3 is in the horizontal direction, for example, in the horizontal direction, the closed door body 1 is in a state capable of unlocking.

  When the opening / closing operation member 3 is not used or is unlockable, the entire shape of the opening / closing operation member 3 is “heavy” as viewed from above. Then, the bent distal end side of the opening / closing operation member 3 is inserted through the shaft hole 25a of the operation member bearing movable plate 25 on the distal end side of the opening / closing operation member fixture 2, and the gripping portion 32 extending straight in the latter half thereof. Are arranged in parallel to the side surfaces of the upper plate piece 21 and the lower plate piece 22 of the opening / closing operation member fixture 2.

  The opening / closing operation member 3 is a locking piece at an interval of 180 degrees on a circular side peripheral surface that protrudes forward from the shaft hole 25a of the operation member bearing movable plate 25 out of the distal end side that is bent in a “hoop shape”. Each of 33 is formed to project. The locking pieces 33 formed on the side peripheral surface on the distal end side of the opening / closing operation member 3 are positioned on both the upper and lower sides in a horizontal direction, for example, in a horizontal state when not in use or in an unlockable state, and the grip portion 32 extends upward. It is located on both the left and right sides when locked.

  One side surface of the lock piece 33 on the distal end side of the opening / closing operation member 3 is inserted and engaged with the receiving groove 41 of the opening / closing operation member receiving piece 4 so that the front end portion 31 is rotated at a predetermined rotation angle, for example, 90 degrees upward. When it is done, it will be in the position which adjoins in the state parallel to the groove opening outer periphery 41a of the receiving groove 41, and will be in the locked state which the closed door body 1 does not open.

  That is, when a force is applied to the distal end portion 31 of the opening / closing operation member 3 from the receiving groove 41, one side surface of the one locking piece 33 comes into contact with the groove opening outer peripheral edge 41a of the receiving groove 41, It functions to prevent the operating member bearing movable plate 25 inserted at the front end side from rotating and prevent the front end portion 31 of the opening / closing operating member 3 from coming out of the receiving groove 41.

  This is because the front end portion 31 of the opening / closing operation member 3 starts to enter into the receiving groove 41 of the opening / closing operation member receiving piece 4 in a state of being inclined sideways with respect to the receiving groove 41 and is straight when fully inserted. become. Similarly, when pulling out from the receiving groove 41, it is gradually tilted sideways from the initial straight state and pulled out. When the tip portion 31 starts to come out and is tilted sideways, the angle on one side of the side peripheral surface on the tip side of the opening / closing operation member 3 and the groove opening outer peripheral edge 41a of the receiving groove 41 becomes an acute angle smaller than 90 degrees. .

  In the locked state, at the same time as the tip end portion 31 begins to slightly slip out of the receiving groove 41 and starts to tilt sideways to the groove opening outer peripheral edge 41a of the receiving groove 41 on one side of the locking piece 33 on the same angle side. Since the tip portion 31 contacts first, the tip portion 31 cannot tilt further sideways and does not reach a certain angle necessary for exiting, and the tip portion 31 of the opening / closing operation member 3 exits from the receiving groove 41 of the opening / closing operation member 3. It will not be possible.

  On the other hand, in the unlocked state, the lock piece 33 projected on the side peripheral surface of the opening / closing operation member 3 rotates in a reverse direction at a predetermined rotation angle, for example, 90 degrees, and contacts the groove opening outer peripheral edge 41a of the receiving groove 41. The tip portion 31 inserted and engaged with the receiving groove 41 is gradually inclined laterally from the initial straight state and can be pulled out.

  The opening / closing operation member receiving piece 4 fulfills the function of fixing the door body 1 in a closed state by the distal end portion 31 of the opening / closing operation member 3 being inserted and engaged. The opening / closing operation member receiving piece 4 is located on the opposite side of the outside of the frame 12 to which the peripheral edge of the door body 1 is closely attached when the sluice is closed, that is, the inner rear part of the frame 12 on the side opposite to the side to which the hinge 11 is attached. At the inner rear part, the door body 1 is attached to the rear part on the back surface 1a side so as to be freely put in and out.

  The opening / closing operation member receiving piece 4 is formed of a plate piece, and can be stored in and taken out of the storage place 42 so that the elevation angle is freely rotatable between the upward direction and the horizontal direction with the lower side as a fulcrum. A rotating shaft 43 having a circular cross section is fixed laterally to the base end of the plate piece which is the lower end when it is upward. Both ends of the rotating shaft 43 protrude from both side ends of the plate piece to both sides, and are supported on both side surfaces of the storage place 42. A storage place 42 in which the opening / closing operation member receiving piece 4 is stored is provided on the inner rear side of the frame body 12.

  An opening / closing operation member 3 attached to the opening / closing operation member mounting tool 2 is disposed on the back surface 1a side of the door body 1 near the storage place 42. When the door body 1 is closed, the opening / closing operation member receiving piece 4 is taken out from the storage place 42 by rotating downward about the rotation shaft 43 as a fulcrum, and is in contact with the horizontal lower surface of the storage place 42 and tilted horizontally. In this state, the distal end side protrudes, and when not in use, it is in an upward state and is stored in the storage place 42.

  In the opening / closing operation member receiving piece 4, a receiving groove 41 into which the distal end portion 31 of the opening / closing operation member 3 is inserted and engaged is formed near the distal end side of one end face of the plate piece. The plate piece of the opening / closing operation member receiving piece 4 which is inclined in the horizontal state and protrudes rearward on the back surface 1a side of the door body 1 is parallel to the back surface 1a side of the closed door body 1, but the receiving groove 41 is the door body. 1 is formed near the front end side of one side end face of the plate piece farther from the back surface 1a side. Further, a projecting piece 44 is formed on one surface side of the plate piece near the receiving groove 41 which becomes the lower surface when tilted horizontally.

  The receiving groove 41 of the opening / closing operation member receiving piece 4 is formed in a semicircular concave shape so that the semicircular tip portion 31 of the opening / closing operation member 3 can be inserted and engaged. The receiving groove 41 is formed in a concave shape corresponding to the convex end portion 31 having a round shape close to a semi-spherical shape, and the leading end portion 31 of the opening / closing operation member 3 is loosely fitted in the receiving groove 41. Absent. Both side surfaces which are the outer peripheral edge of the receiving groove 41 on one side end surface of the plate piece are formed as flat surfaces.

  When the opening / closing operation member 3 is used, the lock pieces 33 projecting from both side peripheral surfaces on the front end side are close to both side end surfaces of the groove opening outer peripheral edge 41a of the receiving groove 41. The side end surface of the groove opening outer peripheral edge 41a of the receiving groove 41 is brought into contact with one side surface of the lock piece 33 as described above when the distal end portion 31 of the opening / closing operation member 3 is about to come out of the receiving groove 41, and this lock piece. By pressing 33, it is prevented from coming out and the watertightness between the peripheral edge of the door body 1 and the frame body 12 is prevented from being lowered.

  An attachment / detachment locking piece 5 is attached to the back surface 1a of the door body 1. The attachment / detachment locking piece 5 is horizontally swiveled away from the back surface 1a of the door body 1 with the vertical shaft 24 on the base end side as a fulcrum when the opening / closing operation member attachment 2 to which the opening / closing operation member 3 is attached is not in use. Thus, the opening / closing operation member fixture 2 is locked to the rear surface 1a side of the door body 1 to prevent the opening.

  The fixture attaching / detaching locking piece 5 is formed with a hook piece 51 in which the front end side of the plate piece is bent downward, for example, at a right angle. The inner corner side 51a of the flange 51 bent downward is the side farther from the back surface 1a of the door body 1 on the side straddling the upper plate piece 21 of the opening / closing operation member fixture 2 to which the opening / closing operation member 3 is attached. The attachment / detachment locking piece 5 prevents the opening / closing operation member attachment 2 from opening by being hooked on the other side end face of the upper plate piece 21 from above. Further, in order to prevent the latched opening / closing operation member attachment 2 from coming off from there, the projecting end 51b of the flange 51 is further bent inward, for example, at a right angle.

  The attachment / detachment locking piece 5 has a base end side 52, which is opposite to the distal end side on which the flange piece 51 is formed, on a bearing 53 protruding from the back surface 1 a of the door body 1 with an elevation angle upward from the horizontal. It is pivotally supported so that it can freely rotate vertically. The lower plate 53a formed at the lower portion of the bearing 53 is formed horizontally, and the fixture attaching / detaching locking piece 5 is oriented horizontally by the lower surface side of the plate piece coming into contact with the lower plate 53a of the bearing 53. .

  The distal end side of the attachment / detachment locking piece 5 on which the flange piece 51 is formed is applied with a moment force that always rotates in the horizontal direction from the base end side as a fulcrum by its own weight, and stops in a horizontal state. . Utilizing this force, the attachment / detachment locking piece 5 is configured such that the opening / closing operation member mounting tool 2 is separated from the back surface 1a of the door body 1 by the hook piece 51 locking the one end face of the upper plate piece 21. It prevents it from opening in the direction.

  In other words, the attachment / detachment locking piece 5 is bent by its own weight so that the lower surface of the plate piece crosses the upper surface of the upper plate piece 21 of the opening / closing operation member attachment device 2 from the upper side and downwards. The inner corner side 51a of the collar piece 51 abuts on the side end surface of the upper plate piece 21 on the side farther from the back surface 1a of the door body 1, and the opening / closing operation member mounting tool 2 opens in a direction away from the back surface 1a side of the door body 1. To prevent.

  Further, the outer corner side 51c of the collar piece 51 formed at the tip of the fixture attaching / detaching locking piece 5 is formed in an inclined surface having an angle of 45 degrees, for example, downward in the horizontal direction toward the back surface 1a side of the door body 1. ing. When the opening / closing operation member fixture 2 is returned to the back surface 1a side of the door body 1 when not in use, the hook piece 51 side bent downward can be automatically pushed up. Because.

  That is, when the side end surface near the back surface 1a of the upper plate piece 21 of the opening / closing operation member fixture 2 to be returned to the back surface 1a side of the door body 1 hits the inclined surface of the outer corner side 51c of the front end piece 51, along the inclined surface. Thus, the distal end side of the fixture attaching / detaching locking piece 5 is automatically pushed upward from the horizontal direction. In the opening / closing operation member fixture 2, the width direction of the upper plate piece 21 passes below the protruding end 51 b at the lower end bent downward.

  Then, the hook piece 51 at the tip of the fixture attaching / detaching locking piece 5 is lowered horizontally from the obliquely upward state, and the inner corner side 51a bent downward is the side end face on the side far from the back surface 1a of the upper plate piece 21. The opening / closing operation member fixture 2 is prevented from opening freely. At this time, a part of the lower surface of the lower plate piece 22 of the opening / closing operation member mounting tool 2 is locked to the upper surface side of the protruding end 51 b at the lower end of the collar piece 51.

  A U-shaped handle 1d is attached to the center of the edge frame girder 1b on the upper side of the door body 1 downward. Moreover, the door body latching piece 13 which latches the door body 1 of the state opened completely is provided in the sluice wall surface of the side in which the hinge 11 was provided. The door body locking piece 13 is pivotally supported by a bearing 14 whose base end side is attached to the upper end side of the sluice wall surface so as to be rotatable in the vertical direction. A locking groove 13 a that engages with a horizontal bar-shaped portion of the U-shaped handle 1 d is formed on the lower surface on the distal end side of the door body locking piece 13.

  That is, when the door body locking piece 13 is lowered from the upper side toward the handle 1d of the door body 1 in a state where the sluice is completely opened at 180 degrees with the hinge 11 as a fulcrum, the engagement formed on the lower surface on the distal end side is lowered. The stop groove 13a is engaged with the horizontal portion of the handle 1d from above, and the horizontal portion of the handle 1d is sandwiched between both side surfaces in the locking groove 13a. The door body 1 is maintained in a completely open state by the handle 1d being engaged and locked by the door body locking piece 13.

  For example, a heavy steel plate is used as the door locking piece 13, so the door locking piece 13 does not easily rotate upward due to its own weight, and the open door 1 is alone. It won't close suddenly. When closing the door body 1, an operator lifts the distal end side of the door body locking piece 13 by hand, moves the locking groove 13 a above the handle 1 d to release the engaged state, and the door body 1. The sluice is closed by turning 180 degrees.

Next, the operation based on the configuration of the embodiment for carrying out the above-described device will be described below.
In the event of an emergency, if it becomes necessary to immediately close the door body 1 of the sluice, the front end side of the door body locking piece 13 that has locked the fully open door body 1 is lifted to the lower surface on the front end side. The formed locking groove 13 a is moved above the handle 1 d of the door body 1. As a result, the handle 1d of the door body 1 is disengaged from the door body locking piece 13, the handle 1d is gripped, the door body 1 is rotated 180 degrees, and the door body 1 is directed toward the sluice frame body 12. Close 1

  Next, the opening / closing operation member receiving piece 4 housed in the storage space 42 on the inner rear side of the frame body 12 provided on the side opposite to the side on which the hinge 11 is attached is tilted toward the back surface 1 a side of the door body 1. . As a whole, the opening / closing operation member receiving piece 4 rotates to the near side with the rotation shaft 43 on the lower end side as a fulcrum and falls into a horizontal state. The opening / closing operation member receiving piece 4 is in a state parallel to the vicinity of the back surface 1a side of the door body 1.

  Subsequently, on the back surface 1a side of the door body 1, the tip end side of the attachment attaching / detaching engagement piece 5 that has engaged the opening / closing operation member attachment 2 attached with the opening / closing operation member 3 is lifted, and the vertical shaft 24 is used as a fulcrum. The opening / closing operation member mounting tool 2 is horizontally rotated toward the opening / closing operation member receiving piece 4 side that appears in a tilted state. The upper plate piece 21 of the distal end side of the opening / closing operation member mounting tool 2 that is horizontally rotated reaches near the upper portion of the receiving groove 41 of the opening / closing operation member receiving piece 4. Similarly, the lower plate piece 22 arranged below the upper plate piece 21 reaches near the lower side of the receiving groove 41 of the opening / closing operation member receiving piece 4. That is, the tip end side of the opening / closing operation member receiving piece 4 in the horizontal state is in a state of being interposed between the upper plate piece 21 and the lower plate piece 22 that have been rotated in the horizontal direction.

  An actuating member bearing movable plate 25 is provided at the front end side of the upper plate piece 21 and the lower plate piece 22 of the opening / closing actuating member fixture 2, and the actuating member bearing movable plate 25 that has been rotated is the back surface 1 a of the door body 1. As viewed from the side, the opening and closing operation member receiving piece 4 reaches the diagonally rear side of the receiving groove 41. At that time, the gripping portion 32 of the opening / closing operation member 3 that has been rotated integrally at the side position of the opening / closing operation member mounting tool 2 is grasped and directed toward the rear side away from the back surface 1a of the door body 1. Turn horizontally.

  The distal end side of the opening / closing operation member 3 that is bent into a “hump” shape is inserted into the shaft hole 25a of the operation member bearing movable plate 25, and the rounded tip portion 31 that passes through the shaft hole 25a is By horizontally rotating the grip portion 32 toward the rear side, the operating member bearing movable plate 25 rotates about the vertical axis. The rounded tip portion 31 passing through the shaft hole 25a rotates integrally with the rotation of the operating member bearing movable plate 25, and from a position away from the receiving groove 41 of the opening / closing operating member receiving piece 4. It approaches the receiving groove 41, and a part thereof is inserted into the receiving groove 41 while being inclined sideways and starts to engage.

  Furthermore, when the gripping portion 32 of the opening / closing operation member 3 is horizontally rotated toward the rear side without taking a rest, the opening / closing operation started to be inserted into the receiving groove 41 of the opening / closing operation member receiving piece 4 while being inclined sideways. The distal end portion 31 of the member 3 changes from a state inclined sideways to a straight state with respect to the receiving groove 41, and is firmly inserted and engaged with the receiving groove 41.

  In this state, the watertight rubber 1c attached to the back side of the edge frame girder 1b of the door body 1 of the sluice is pressure-bonded to the surface of the frame body 12 to measure watertightness. Or it becomes possible to prevent the penetration | invasion of fresh water reliably. At this time, the door body 1 with the sluice closed is crimped to the frame body 12 by being pulled backward by the opening / closing operation member fixture 2. Further, the receiving groove 41 of the opening / closing operation member receiving piece 4, the distal end portion 31 of the opening / closing operation member 3, the distal end side, and the shaft hole 25 a of the operation member bearing movable plate 25 are positioned on the same straight line.

  Thereafter, the holding portion 32 of the opening / closing operation member 3 is moved so that the rounded tip portion 31 of the opening / closing operation member 3 inserted and engaged with the receiving groove 41 of the opening / closing operation member receiving piece 4 does not come out of the receiving groove 41. A predetermined rotation angle, for example, 90 degrees upward at a right angle, is turned into a locked state. As described above, the receiving groove 41 of the opening / closing operation member receiving piece 4, the distal end portion 31 of the opening / closing operation member 3, the distal end side, and the shaft hole 25 a of the operation member bearing movable plate 25 are located on the same straight line extension. The tip end side of the opening / closing operation member 3 inserted through the shaft hole 25a of the operation member bearing movable plate 25 is rotated 90 degrees around the axis of the shaft hole 25a and is inserted into the receiving groove 41 in a semi-spherical shape. The near rounded tip portion 31 also rotates 90 degrees around the axis.

  By the way, the locking pieces 33 are formed to protrude on both side peripheral surfaces on the distal end side of the opening / closing operation member 3, but when the distal end portion 31 is inserted into the receiving groove 41, the two locking pieces 33 are arranged on the side periphery on the distal end side. When a situation occurs in which the tip end portion 31 comes out of the receiving groove 41 located above and below the surface, the lock piece 33 does not function to prevent it.

  By rotating the front end side of the opening / closing operation member 3 by a predetermined rotation angle, for example, 90 degrees to be in a locked state, the lock piece 33 positioned on the upper side of the side peripheral surface on the front end side rotates downward by 90 degrees. In addition, the lock piece 33 located on the lower side of the side peripheral surface rotates 90 degrees upward, and one side surface of each lock piece 33 comes close to both sides of the groove opening outer peripheral edge 41 a of the receiving groove 41.

  When the lock piece 33 formed on the side peripheral surface on the distal end side of the opening / closing operation member 3 is in a locked state close to the groove opening outer peripheral edge 41a of the receiving groove 41 of the opening / closing operation member receiving piece 4, the lock piece 33 is opened / closed. The function of preventing the distal end portion 31 of the operating member 3 from coming out of the receiving groove 41 is achieved.

  This is because when the front end portion 31 of the opening / closing operation member 3 is extracted from the receiving groove 41 of the opening / closing operation member receiving piece 4, the opening / closing operation member 3 is gradually inclined in the lateral direction from the initial straight state. When the distal end portion 31 is tilted laterally because it is pulled out, the angle on one side of the side peripheral surface on the distal end side of the opening / closing operation member 3 and the groove opening outer peripheral edge 41a of the receiving groove 41 is an acute angle smaller than 90 degrees. become.

  In the locked state, at the same time as the tip end portion 31 begins to slightly slip out of the receiving groove 41 and starts to tilt sideways to the groove opening outer peripheral edge 41a of the receiving groove 41 on one side of the locking piece 33 on the same angle side. Abut first. As a result, the distal end portion 31 cannot tilt further sideways and does not reach a certain angle required to exit, and the distal end portion 31 of the opening / closing operation member 3 can exit from the receiving groove 41 of the opening / closing operation member 3. Disappear. In this way, the tip portion 31 of the opening / closing operation member 3 is prevented from coming out of the receiving groove 41 of the opening / closing operation member 3.

  In this way, by simply pulling the grip portion 32 of the opening / closing operation member 3 toward the hand side, the edge frame girder 1b at the periphery of the door body 1 can be simply crimped to the frame body 12, and the water tightness of the door body 1 can be obtained. It is possible to close the sluice in an extremely short time in an emergency.

On the other hand, when the closed door 1 is opened, it is performed in the reverse order to the closing operation described above.
That is, the gripping portion 32 of the upward opening / closing operation member 3 is grasped and turned sideways by a predetermined rotation angle, for example, 90 degrees to release the locked state. After that, the gripping portion 32 of the opening / closing operation member 3 is pushed toward the back surface 1a side of the door body 1 to rotate horizontally.

  By this operation, the distal end portion 31 of the opening / closing operation member 3 inserted and engaged in the receiving groove 41 of the opening / closing operation member receiving piece 4 comes out. The grip portion 32 of the opening / closing operation member 3 is rotated to a position parallel to the side of the opening / closing operation member mounting tool 2, and then the opening / closing operation member mounting tool 2 is a door body around the vertical shaft 24 on the base end side. 1 is rotated toward the back surface 1a side.

  On the back surface 1a of the door body 1, the fixture attachment / detachment locking piece 5 is directed rearward in a horizontal state, and the one end face of the upper plate piece 21 of the rotating opening / closing operation member attachment 2 is attached / detached. It contacts the outer corner 51c of the flange 51 at the tip of the piece 5. Since the outer corner side 51c of the collar piece 51 of the fixture attaching / detaching locking piece 5 is formed in an inclined surface inclined downward toward the back surface 1a side of the door body 1 in the horizontal state, When the one side end surface of the plate piece 21 comes into contact with the fixture attaching / detaching locking piece 5, the hook piece 51 at the distal end rotates upwardly around the base end side 52 along the inclined surface of the outer corner side 51c. Pushed up.

  Then, when the width direction of the upper plate piece 21 of the opening / closing operation member fixture 2 passes through the protruding end 51b of the lower end bent downward of the flange piece 51 of the fixture attachment / detachment locking piece 5, the attachment / detachment locking piece 5 The lower end 51b of the lower end 51 of the upper end 51 is bent downward toward the far side of the upper plate 21. As a result, the opening / closing operation member mounting tool 2 to which the opening / closing operation member 3 is attached is automatically locked to the back surface 1a side of the door body 1 by the mounting tool attaching / detaching locking piece 5.

  After the opening / closing operation member fixture 2 is locked to the back surface 1a side of the door body 1, the front end side of the door body locking piece 13 is lifted, the handle 1d of the door body 1 is gripped, and the door body 1 is turned 180 degrees sideways. The door body 1 is held in an open state by fully opening and lowering the locking groove 13a formed on the lower surface of the front end side of the door body locking piece 13 from the upper side to engage with the handle 1d of the door body 1. Will be.

  It should be noted that the present invention is not limited to the mode for carrying out the above-described invention, and various modifications can be made without departing from the spirit of the present invention.
