The outer diameter of the rotating shaft 5a is such that the rotating shaft 5a does not drop off from other than the upper and lower ends of the groove 33 of the edge member 32, and the rotating shaft 5a can freely rotate in the groove 33. Slightly smaller than.
In the present embodiment, both the edge member 32 and the universal pin 5 are made of aluminum or an aluminum alloy. For this reason, the groove 33 and the free pin 5 are not deformed by a force that allows a person to open the hinged door 4, and the edge member 32 and the free pin 5 are deformed or detached during normal use and emergency unlocking described later. There is nothing.

As shown in FIG. 3, the lock portion 9 includes a lock body 10 attached to the hinged door 4 and a receiving member 26 attached to the panel 3.
The lock body 10 restricts the orientation of the universal pin 5 so that the tip of the wing portion 5b of the universal pin 5 faces in the direction from the hanging base to the door during normal use. Further, during emergency unlocking, the lock body 10 is disengaged from the receiving member 26 by an operation from the outside of the room, and further separated from the free pin 5 so as not to restrict the direction of the free pin 5 (see FIG. 9).

  In the present embodiment, the lock portion 9, the edge member 32, and the universal pin 5 constitute an emergency unlocking mechanism in which the hinged door 4 is double-opened in an emergency.

An example of the lock body 10 capable of switching the orientation of the universal pin 5 in this way will be described below.
The lock body 10 includes a lower seat 11, a lock operation piece mounting base member 13, a stopper 14, a buffer piece 15, a lock operation piece 16, and a pivot shaft structure 17.
As shown in FIG. 3, the lower seat 11 is attached to the inner side surface of the hinged door near the door tip by screws 12. The lower seat 11 is fixed to the hinged door in the horizontal direction.

  At the center of the first and second screws 12 from the base end side (the left end side in the drawing) of the lower seat 11, a turning guide member through-hole having a straight line parallel to the upper and lower sides and an arc-shaped base end / tip side 11b is formed.

  The lock operation piece mounting base member 13 is connected to the lower seat 11. Furthermore, the lock operation piece 16 is fitted to the lock operation piece mounting base member 13 so as to be slidable within a predetermined range.

Further, the lock operation piece mounting base member 13 includes a stopper 14 for preventing the lock operation piece 16 from going too far toward the receiving member 26, and the lock operation piece mounting base member 13 when the lock operation piece mounting base member 13 comes into contact with the panel 3. A shock-absorbing piece 15 that absorbs the impact is fixed.
The lock operation piece 16 is supported by the lock operation piece attachment base member 13 so as to wrap the lock operation piece attachment base member 13 so as to be slidable along the longitudinal direction of the lock operation piece attachment base member 13. .
An engaging portion 16 b that engages with the receiving member 26 is formed at the end of the locking operation piece 16 that faces the receiving member 26.

The pivot shaft component 17 holds the lock operation piece 16 at a predetermined position with respect to the lower seat 11, and when the predetermined operation is performed from outside the room 1, the lock operation piece 16 is moved with respect to the lower seat 11. Rotate freely.
The swivel shaft structure 17 includes a swivel shaft member 19 that penetrates the hinged door 4, and an operation unit 18 that is positioned outside the hinged door 4 at the end of the swivel shaft member 19.
The swivel shaft member 19 is connected to the lock operating piece 16 and the lower seat 11 by an urging force of a spring during normal use, and receives an external force that resists the urging force of the spring when an emergency unlocked state is established. The engagement with the lower seat 11 is released.

  The receiving member 26 is fixed to the panel 3 at a position where the engaging portion 16b of the lock operating piece 16 is engaged by a screw. And the front-end | tip engaging part 16b of the lock operation piece 16 can be engaged with the latching receiver 26a of the receiving member 26 so that engagement / disengagement is possible.

Next, the operation of the emergency unlocking mechanism, the hinged door device, and the private room unit 100 of this embodiment will be described. FIG. 7 is an explanatory view showing a locked state in the emergency unlocking mechanism. FIG. 8 is an explanatory view showing an emergency unlocked state in the emergency unlocking mechanism. FIG. 9 is an explanatory view showing an emergency unlocked state in the emergency unlocking mechanism.
As shown in FIG. 7, the state in which the distal end engaging portion 16 b of the lock operation piece 16 is engaged with the locking receiver 26 a of the receiving member 26 is a door locking state in which the hinged door 4 is fixed to the panel 3. . If the user in the room 1 inside the hinged door 4 (upper side in FIG. 7) moves in the direction separating the lock operating piece 16 from the receiving member 26 (leftward in FIG. 7) in the door-locked state, the door is locked. The front end engaging portion 16b of the operation piece 16 is disengaged from the locking receiver 26a of the receiving member 26, and the hinged door 4 can be opened inward (see the upper side in FIG. 7 and FIG. 3). However, when the lock operation piece 16 is oriented in the horizontal direction, the lock operation piece 16 and the lock operation piece attachment base member 13 are in a state where the wing portion 5b of the universal pin 5 is pressed. Therefore, since the protruding end of the wing portion 5b interferes with the edge member 31, the hinged door 4 cannot be opened outward (downward in the drawing).
Furthermore, when the lock operation piece 16 is oriented horizontally, the gap between the door 4a of the hinged door 4 and the panel 3 (the gap between the edge member 31 and the edge member 32 in the present embodiment) Covered by the wings 5b. Thereby, the wing | blade part 5b functions as a blindfold which prevents looking into the room between the door tip of the hinged door 4, and the panel 3. FIG.

Next, the case where the hinged door 4 is operated as an outward opening will be described.
If the person outside the hinged door 4 finds or notices that the user inside the hinged door 4 cannot move in the state where the hinged door 4 is locked, the hinged door 4 is moved from outside the room 1. It needs to be opened. Thus, when the hinged door 4 is in the locked state, the unlocking of the hinged door 4 from the outside of the room 1 is the emergency unlocking in this specification.
In the emergency unlocked state, for example, the discoverer holds a coin or the like, engages the end of the coin or the like with the operation unit 18, and pushes it in the middle of the room 1. Then, the turning shaft member 19 is pushed in a direction approaching the lock operation piece 16, and the engagement between the turning shaft member 19 and the lower seat 11 is released. As a result, the lock operation piece mounting base member 13 and the lock operation piece 16 are united and can freely pivot about the pivot shaft member 19. If the discoverer turns the coin 90 degrees in a direction in which the tip engaging portion 16b of the lock operation piece 16 faces downward, the tip engagement portion 16b of the lock operation piece 16 turns downward.
The distal end engaging portion 16b of the lock operating piece 16 sandwiched between the outer side surface (lower surface in the drawing) of the receiving member 26 and the inner side surface (upper surface in the drawing) of the panel 3 is the receiving member 26 and the panel 3 The hinged door 4 can be turned not only inward (upward in the drawing) but also outward (downward in the drawing).

  As shown in FIG. 9, when the lock operating piece 16 turns downward, the lock operating piece 16 becomes parallel to the direction in which the free pin 5 extends, and thus the operation of the free pin 5 rotating around the rotation shaft 5a is restricted. Disappear. For this reason, the wing part 5b of the universal pin 5 does not restrict the operation range of the hinged door 4 so that the hinged door 4 is opened inward, and moves around the rotation axis 5a as the hinged door 4 moves toward the outside of the room. It rotates to allow the hinged door 4 to open outward.

Thus, in the emergency unlocked state, the hinged door 4 operates as an outward opening, so that a user in the room 1 can be rescued immediately without being pushed into the interior with the hinged door 4. In addition, when the user is leaning against the hinged door 4, the hinged door 4 may not be opened if the hinged door 4 is left inward, but in this embodiment, the hinged door 4 is opened outward. By doing so, the hinged door 4 can be easily opened.

When returning to the normal use state from the emergency unlocked state, first, the hinged door 4 is changed from the state opened to the outside of the room to the closed state. Subsequently, the distal end engaging portion 16b of the lock operation piece 16 is turned 90 ° upward along the inner surface of the edge member 31 and the panel 3 on the room 1 side. Thereby, the turning shaft member 19 is engaged with the lower seat 11 again, and the lock operation piece 16 can hold the state oriented in the horizontal direction together with the lock operation piece attachment base member 13. Thereby, the hinged door 4 can be set to a locked state or an unlocked state by moving the lock operation piece 16 with respect to the receiving member 26 in an approaching direction or a separating direction.
At this time, the universal pin 5 is held by the lock operation piece 16 in a blinding direction that covers the gap between the door tip and the panel 3 again, and functions again as a member that restricts the hinged door 4 to be inwardly opened.

Thus, according to the emergency unlocking mechanism, the hinged door device, and the individual chamber unit 100 of the present embodiment, the hinged door 4 is double-opened by rotating the universal pin 5, so that the inner hinged door can be easily opened in an emergency. And it is hard to break.
Further, the universal pin 5 functions as a blindfold in addition to restricting the hinged door 4 to be inwardly opened.
Furthermore, since the universal pin 5 is configured to rotate with respect to the edge member 32, the universal pin 5 may be a hard member. For this reason, since the free pin 5 is hard to be damaged, maintenance is easy.
Moreover, since it is not necessary to deform | transform the universal pin 5 itself, the intensity | strength fall by a deformation | transformation is repeated, and it is excellent in maintainability.
Moreover, since the universal pin 5 rotates freely with respect to the edge member 32, the operation | work which returns from an emergency unlocked state to a normal use state is easy.

As shown in FIG. 11, the external operation unit 104 can be attached to the hinged door 4 so as to be exposed to the outside of the room 1 in a state where the hinged door 4 closes the entrance / exit.
As shown in FIGS. 13 and 14, the external operation unit 104 includes an outer cylinder part 105 fixed to the base part 101, and an operation that is arranged inside the outer cylinder part 105 and is rotatable with respect to the outer cylinder part 105. And an input shaft 106.

14 is a cylindrical member having an opening 105a that allows a predetermined key 140 to reach the operation input shaft 106. The outer cylinder 105 shown in FIG. Furthermore, a thread groove 105 b for screwing a support cylinder part 109 (described later) provided in the main body part 108 is formed on the inner peripheral surface of the outer cylinder part 105.
The opening 105a formed in the outer cylinder portion 105 is preferably a small-diameter opening for the purpose of preventing the operation input shaft 106 from being rotated by mischief. Further, the opening 105 a formed in the outer cylinder portion 105 may have a contour shape corresponding to the shape of the key 140 for the purpose of enabling the operation input shaft 106 to be rotated only by the predetermined key 140. . In the present embodiment, the shape of the opening 105a is hexagonal for the purpose of allowing the outer cylinder 105 to be screwed into the support cylinder 109 using a hexagon wrench. If the contour shape of the opening 105a is non-circular, the same effect as in the case of a hexagonal shape can be obtained even if it is other than a hexagonal shape.

  As shown in FIG. 14, the operation input shaft 106 has a coupling groove 106 a having a non-circular cross section at a portion directed to a transmission shaft portion 126 described later in the drive portion 125, and the opening portion 105 a of the outer cylinder portion 105. It is a substantially rod-shaped member having a concavo-convex shape 106b that meshes with the key 140 in a portion directed toward the surface. The operation input shaft 106 is connected to the outer cylinder portion 105 so as to be rotatable with respect to the outer cylinder portion 105 about the central axis of the outer cylinder portion 105 as a rotation center. Specifically, the operation input shaft 106 is formed with a groove 106c that extends over the circumference of the operation input shaft 106 when viewed from the center axis direction of the operation input shaft 106, and enters the groove. The operation input shaft 106 is connected to the outer cylinder portion 105 by a retaining plate 107 (see FIGS. 11 and 14) fixed to the outer cylinder portion 105. As a result, the central axis of the operation input shaft 106 and the central axis of the outer cylindrical portion 105 are maintained substantially coaxial.

As shown in FIG. 14, the main body 108 is connected to the external operation unit 104 and the mounting plate 102. The main body 108 is capable of rotating with respect to the mounting plate 102 around a rotation axis directed in the thickness direction of the mounting plate 102. In the present embodiment, the rotation axis of the main body 108 with respect to the mounting plate 102 is coaxial with the central axis of the operation input shaft 106 and the central axis of the transmission shaft 126. In other words, in this embodiment, the rotation axis of the main body 108 with respect to the mounting plate 102 coincides with the rotation axis of the transmission shaft 126 when the operation input shaft 106 is rotated by the key 140.
In the main body 108, when the mounting plate 102 is fixed to the hinged door 4, the door-side end of the slide bolt 132 can be moved upward from the horizontal state of the slide bolt 132. Further, the main body 108 has the slide bolt 132 in a state where the end of the slide bolt 132 on the door end side is higher than the end of the slide bolt 132 on the suspension base side when the mounting plate 102 is fixed to the hinged door 4. It can rotate with respect to the mounting plate 102 until it becomes the original horizontal state. The rotation range of the main body 108 is restricted so that the end of the slide bolt 132 on the door end side does not descend from the horizontal state.
Further, in the main body 108, when the main body 108 is in a horizontal state, the door end side portion is heavier than the hanging shaft side portion than the rotation shaft of the main body portion 108 than the rotation shaft of the main body portion 108. For this reason, the main body 108 needs an external force that resists gravity in order to rotate the door end side portion of the main body 108 to move upward.
The main body part 108 includes a support cylinder part 109 fixed to the mounting plate 102 and connected to the external operation part 104, and a guide part 111 connected to the support cylinder part 109.

  The support cylinder portion 109 is fixed to the mounting plate 102. A screw thread 109 a is formed on the outer peripheral surface of the support cylinder portion 109 to be screwed into a screw groove formed on the inner peripheral surface of the outer cylinder portion 105. The outer cylinder part 105 and the support cylinder part 109 can absorb the difference in thickness of the hinged door 4 by setting the insertion length of the screw thread 109a to the screw groove 105b to an arbitrary length. In the present embodiment, the support cylinder portion 109 is fixed to the mounting plate 102 by a spring retaining ring 110. Note that the support cylinder portion 109 may be integrally formed with the mounting plate 102.

The guide part 111 is connected to the support cylinder part 109 so as to be rotatable around the central axis of the support cylinder part 109. For this reason, in this embodiment, the guide part 111 of the main body part 108 can rotate around the rotation axis of the transmission shaft part 126 with respect to the mounting plate 102.
The guide portion 111 includes an accommodating portion 112 that is connected to the supporting cylinder portion 109 so as to be rotatable around the central axis of the supporting cylinder portion 109, a lid portion 118 attached to the accommodating portion 112, and the accommodating portion 112.

The ball 115 of the click mechanism 113 is pressed against the inner surface of the slide bolt 132 by the spring 114. For this reason, when the slide bolt 132 moves linearly with respect to the housing portion 112, a click feeling and a click sound are generated when the ball 115 is fitted in the click groove 132d formed on the inner surface of the slide bolt 132. In the present embodiment, the click mechanism 113 can provide a click feeling at two positions, a position where the slide bolt 132 is closest to the receiving member 133 side and a position where the slide bolt 132 is farthest from the receiving member 133. The click grooves 132d into which the balls 115 are fitted are formed at two locations separated in the forward and backward direction of the slide bolt 132.

As shown in FIG. 11, the opening / closing direction restricting portion 116 includes a first contact portion 116 a that can contact the panel 3 and a second contact portion 116 b that can contact the wing portion 5 b of the universal pin 5. .

The lid portion 118 is provided with a rail 118a for connecting the guide portion 111 and the slide bolt 132 and guiding the slide bolt 132 to the guide portion 111 so as to be linearly movable.

  The connecting body 119 connects the housing part 112 and the lid part 118 and restricts the forward and backward movement of the slide bolt 132 with respect to the guide part 111, and the housing part 112 at a position away from the first connecting body 120. And a second connecting body 124 that connects the lid portion 118 to each other.

  The first connecting body 120 includes a stopper screw 121 that is screwed into the housing portion 112 from the housing portion 112 toward the lid portion 118, and a non-circular nut 122 that fits into the lid portion 118 and fits into the stopper screw 121.

The non-circular nut 122 is a hexagonal nut in this embodiment, and is inserted into a recess 118b formed in the lid portion 118 corresponding to the outer shape of the hexagonal nut.
An end portion of a stopper screw 121 that extends through the hexagon nut toward the slide bolt 132 in the first connecting body 120 can abut on a stopper, which will be described later, formed on the slide bolt 132.
Thus, in this embodiment, the 1st coupling body 120 which fixes the accommodating part 112 and the cover part 118 functions as the movement control part 123 which controls the forward / backward movement of the slide bolt 132 with respect to the guide part 111. FIG.

  The second coupling body 124 is a screw that is screwed from the lid portion 118 side toward the housing portion 112 side. In the present embodiment, the accommodating portion 112 is previously formed with a screw groove that meshes with the screw that is the second connecting body 124.

  The connecting portion 126a has a non-circular cross section corresponding to the shape of the coupling groove 106a formed in the operation input shaft 106. Further, the depth at which the coupling portion 126a is inserted into the coupling groove 106a is arbitrary, and even when the screwing amount of the outer cylinder portion 105 with respect to the support cylinder portion 109 differs depending on the thickness of the hinged door 4, the transmission shaft portion 126 and The operation input shaft 106 is kept connected.

  As shown in FIG. 15, the gear portion 126b has a disk shape with teeth formed on a part of the outer periphery, and the teeth of the gear portion 126b mesh with an intermediate gear 128 described later.

  Since the transmission shaft portion 126 and the operation input shaft 106 are connected by coupling, the transmission shaft portion 126 is easily coupled to the driving portion 125 by the work of attaching the external operation portion 104 to the base portion 101.

The coupling mechanism 127 shown in FIGS. 14 and 15 uses the rotation of the transmission shaft portion 126 as power for releasing the fixed state between the guide portion 111 and the mounting plate 102 and power for moving the slide bolt 132. It is the power transmission means for doing.
The coupling mechanism 127 includes an intermediate gear 128 that meshes with the gear portion 126 b and rotates within the accommodating portion 112, a fitting member 129 that moves forward and backward by the intermediate gear 128, and a stopper spring that fits the fitting member 129 into the mounting plate 102. 130 (biasing member).

As shown in FIGS. 15 and 16, the intermediate gear 128 has a second gear 128 a meshing with the gear portion 126 b and an uneven portion 128 b into which a part of a rotation transmission member 131 described later is inserted on the outer periphery. The intermediate gear 128 can rotate with respect to the main body 108 inside the main body 108 around a rotation axis parallel to the rotation axis of the transmission shaft 126.
The second gear 128a of the intermediate gear 128 is formed on a part of the outer periphery of the intermediate gear 128 corresponding to the number of teeth of the gear portion 126b.
The uneven portion 128b of the intermediate gear 128 is disposed between a pair of convex portions 128b1 extending from the outer peripheral surface of the intermediate gear 128 in the radial direction of the intermediate gear 128 and spaced apart from each other, and a set of convex portions. And a recess 128b2 for receiving the mating protrusion 131a.

  As shown in FIGS. 12, 14, and 15, the fitting member 129 is supported by the housing groove 117 so as to be able to come into contact with the concavo-convex portion 128 b of the intermediate gear 128 and to advance and retreat within the housing portion 112. Further, the fitting member 129 has a convex portion 129 a that can be fitted to the mounting plate 102.

As shown in FIGS. 12 and 14, the convex portion 129 a can be exposed to the housing portion 112 through the opening formed in the housing groove 117, and is inclined to enter the wedge shape with respect to the recess portion 102 b of the mounting plate 102. It has a surface 129b.
The inclined surface 129b formed in the convex portion 129a is inclined with respect to the advancing / retreating direction of the fitting member 129 and is centered on the rotation axis of the transmission shaft portion 126 in a state where the fitting member 129 is attached to the main body portion 108. The surface is oriented in the circumferential direction.

  The stopper spring 130 shown in FIG. 14 urges the fitting member 129 in a direction in which the convex portion 129 a fits the mounting plate 102 in the advancing and retreating direction of the fitting member 129. In the present embodiment, the stopper spring 130 is a compression spring whose expansion / contraction direction is directed in the forward / backward direction of the fitting member 129.

As shown in FIGS. 14 and 16, the rotation transmitting member 131 has an engaging protrusion 131a inserted into the concave portion 128b2 of the concave and convex portion 128b formed on the intermediate gear 128 of the coupling mechanism 127, and has a gear 131b (first gear) on the outer periphery. (Three gears) having a substantially disk shape.
As shown in FIG. 17, the gear 131 b formed on the outer periphery of the rotation transmission member 131 meshes with a rack 132 a formed on the inner surface of the slide bolt 132, and the rotation transmission member 131 rotates, whereby the slide bolt 132 is guided. It moves linearly with respect to 111 (see FIG. 14). The gear 131 b formed on the outer periphery of the rotation transmitting member 131 has a number of teeth corresponding to the amount of movement of the slide bolt 132 and is formed on a part of the outer periphery of the rotation transmitting member 131.

  As shown in FIGS. 16 and 17, the engagement protrusion 131 a is formed on a surface facing the intermediate gear 128 among a pair of surfaces facing each other in the plate thickness direction of the rotation transmitting member 131. When the engagement protrusion 131a enters the recess 128b2 of the uneven portion 128b formed in the intermediate gear 128 and the rotation transmitting member 131 rotates, the engagement protrusion 131a presses the uneven portion 128b to rotate the intermediate gear 128. .

As shown in FIGS. 12 to 14, the slide bolt 132 (moving body) is movable with respect to the base portion 101, and engages with the receiving member 133 so that the hinged door 4 and the panel are connected via the lock device 9 </ b> A. 3 is a member for connecting the three.
As shown in FIG. 17, the slide bolt 132 has a rack 132 a that meshes with the gear 131 b of the rotation transmission member 131. The rack 132 a provided on the slide bolt 132 is always in mesh with the rotation transmitting member 131 when the slide bolt 132 is attached to the guide portion 111.
A guide 132b for connecting the guide portion 111 and the slide bolt 132 so as to be linearly movable is provided on the inner surface of the slide bolt 132. In the present embodiment, the guide 132 b provided on the inner surface of the slide bolt 132 has an uneven shape for accommodating the rail 118 a formed on the lid portion 118 of the guide portion 111.
Further, as shown in FIGS. 14 and 17, a stopper 132 c capable of contacting the stopper screw 121 is formed on the inner surface of the slide bolt 132. The stopper 132c has a shape projecting from the inner surface of the slide bolt 132 toward the inside of the slide bolt 132. When the stopper screw 121 is tightened, the stopper screw 121 can contact the stopper 132c, and the stopper screw 121 is loosened. The protrusion length is set so that the stopper screw 121 does not hit the stopper 132c.
As shown in FIGS. 12 and 13, a click groove 132 d into which the ball 115 of the click mechanism 113 enters is formed on the inner surface of the slide bolt 132.

  The receiving member 133 (locked member) shown in FIGS. 11 and 14 is not particularly limited as long as the receiving member 133 can be locked to the slide bolt 132 and can be fixed to the panel 3. Appropriately selected and applicable. In this embodiment, the receiving member 133 has a substantially cylindrical shape having a small diameter portion 133a into which a part of the slide bolt 132 enters and a large diameter portion 133b disposed on both sides of the small diameter portion 133a so as to sandwich the small diameter portion 133a therebetween. have.

Next, the operation of the lock device 9A of this embodiment will be described. FIG.18 and FIG.19 is explanatory drawing for demonstrating the effect | action of the locking device of this embodiment.
In this embodiment, as shown in FIGS. 10 and 11, the base portion 101 and the receiving member 133 of the lock device 9 </ b> A are fixed inside the room 1.
In a normal use mode, the locking device 9A is configured to lock the hinged door 4 by connecting the hinged door 4 and the panel 3 while restricting the hinged door 4 to the inner opening only.
That is, in the normal use mode, the locking device 9 </ b> A has the mounting plate 102 fixed to the door end side of the hinged door 4, the receiving member 133 fixed to the panel 3, and the slide bolt 132 from the hinged door 4 toward the receiving member 133. The guide portion 111 is fixed to the mounting plate 102 by the action of the connecting mechanism 127 so that the forward and backward movement of the connecting mechanism 127 occurs.

  Specifically, the stopper spring 130 (see FIG. 14) of the coupling mechanism 127 presses the fitting member 129 (see FIG. 18) to form the convex portion 129a of the fitting member 129 as shown in FIG. The inclined surface 129b and the outer surface of the recess 102b of the mounting plate 102 are in contact with each other. Then, due to the pressing force of the stopper spring 130, the convex portion 129 a of the fitting member 129 meshes with the recess portion 102 b of the mounting plate 102 in a wedge shape. For this reason, the guide part 111 and the attachment plate 102 are fixed without rattling.

  Further, the opening / closing direction restricting portion 116 disposed in the housing portion 112 is disposed at a position where the first contact portion 116a protrudes from the door tip of the hinged door 4 and can interfere with the panel 3 (see FIG. 11). Further, the second abutting portion 116 b of the opening / closing direction regulating portion 116 regulates the rotation of the wing portion 5 b so that the wing portion 5 b fills the gap between the door tip of the hinged door 4 and the panel 3.

When the guide portion 111 and the mounting plate 102 are in a fixed state, the slide bolt 132 can be linearly moved manually inside the room 1. That is, the slide bolt 132 can be manually engaged with the receiving member 133, or the slide bolt 132 can be manually separated from the receiving member 133 (see FIGS. 12 and 13).
In a normal use mode, it is possible to switch the locking state between the slide bolt 132 and the receiving member 133 by linear movement of the slide bolt 132, but the opening / closing direction restricting portion 116 disposed in the guide portion 111 is provided on the panel 3. Since the interference occurs, the hinged door 4 can be locked and unlocked by the lock device 9 </ b> A in a state where the hinged door 4 is restricted to the inner opening.

  On the other hand, when it is necessary to open the hinged door 4 from the outside of the room 1, the unlocking operation is performed using the dedicated key 140 on the external operation unit 104 exposed to the outside of the room 1. First, the slide bolt 132 can be separated from the receiving member 133.

  Specifically, when the operation input shaft 106 is rotated by the key 140 illustrated in FIG. 14, the rotation of the operation input shaft 106 is transmitted to the transmission shaft portion 126 of the drive unit 125. Further, when the transmission shaft portion 126 rotates, the gear portion 126b of the transmission shaft portion 126 rotates the intermediate gear 128. When the intermediate gear 128 rotates, the engaging protrusion 131a that has entered the concave portion 128b2 of the concave and convex portion 128b of the intermediate gear 128 rotates integrally with the intermediate gear 128, whereby the rotation transmitting member 131 rotates and the slide bolt 132 moves linearly. To do.

  When the slide bolt 132 moves linearly and is farthest from the receiving member 133, the ball 115 of the click mechanism 113 enters the click groove 132d of the slide bolt 132 as shown in FIG. The operator who has performed the operation is notified of the unlocking by the click feeling.

  In a state where the slide bolt 132 moves linearly and is separated from the receiving member 133, the opening / closing direction restricting portion 116 of the guide portion 111 can still interfere with the panel 3, and the hinged door 4 is restricted to open inward.

  Here, for example, when the hinged door 4 cannot be opened inward due to a person or object falling on the inner surface of the hinged door 4, the operation input shaft 106 is further rotated in the same direction by the key 140. Then, due to the rotational force transmitted from the operation input shaft 106 to the intermediate gear 128 via the transmission shaft portion 126, the concave and convex portion 128 b of the intermediate gear 128 abuts on the fitting member 129, and the stopper spring 130 biases the fitting member 129. The fitting member 129 is pressed and moved against the biasing force. As a result, the engagement protrusion 131 a formed on the fitting member 129 is pulled out from the recess 102 b of the mounting plate 102. Then, the guide portion 111 is rotatable with respect to the mounting plate 102, and the guide portion 111 is rotated with respect to the mounting plate 102 by the rotational force of the key 140 as shown in FIG.

  When the guide portion 111 rotates with respect to the mounting plate 102, the opening / closing direction restricting portion 116 disposed on the guide portion 111 also rotates integrally with the guide portion 111, so that the opening / closing direction restricting portion 116 does not interfere with the panel 3. The guide part 111 can be moved to the position. Further, the second contact portion 116b of the opening / closing direction restricting portion 116 is separated from the wing portion 5b, and the free pin 5 of the wing portion 5b is rotatable around the rotation shaft 5a. When the opening / closing direction restricting portion 116 is in a position where it does not interfere with the panel 3 and the wing portion 5b is rotatable, the base portion 101 of the locking device 9A does not come into contact with the panel 3, so that the hinged door 4 can be opened outward. Become.

Unlocking a locked private room from the outside is useful in an emergency, but on the other hand, if unlocked by mischief, there is a problem that a private space cannot be maintained. To solve this problem, the emergency unlocking procedure is divided into two stages. In the first unlocking, the slide bolt is slid to allow only the inner opening as in the normal unlocking operation, and the first unlocking is followed. It is known that the slide bolt can be further slid by the second stage of unlocking to allow double opening.
However, in order to slide the slide bolt in two stages, in addition to the movement amount of the slide bolt necessary for normal locking and unlocking operation, the movement amount for the second stage slide is necessary, and the entire locking device is It becomes large.
The design of the lock device may be given priority from the point of constituting a part of the interior. In this case, it is not allowed to increase in size by incorporating a mechanism that slides in two stages, and due to mischief. It is difficult to incorporate a conventional mechanism that can prevent unlocking into a locking device.

  Thus, in the locking device 9A of the present embodiment, the drive unit 125 receives the unlocking operation from the external operation unit 104, so that the slide bolt 132 can be moved in a state in which the guide unit 111 can contact the panel 3. The slide bolt 132 is moved by linear movement along the inner surface of the hinged door 4 until it is separated from the receiving member 133. As a result, as a first stage of the unlocking operation from the outside of the room 1, the unlocking can be performed while the state restricted to the inward opening is maintained.

  Furthermore, in the locking device 9A of the present embodiment, the drive unit 125 is configured such that the base unit 101 is in a state where the slide bolt 132 is separated from the receiving member 133 when the unlocking operation is transmitted from the external operation unit 104. The guide unit 111 is moved by a rotational movement to a position where it does not interfere with 3. As a result, as a second stage of the unlocking operation from the outside of the room 1, the hinged door 4 can be opened outward as well as opened inside.

The lock device 9A according to the present embodiment requires an operation of rotating the key 140 against the biasing force of the stopper spring 130 between the first stage and the second stage of the unlocking operation. Therefore, it is possible to conceal that the second-stage operation is possible for those who do not know that the second-stage operation is necessary. Thereby, the lock device 9A of the present embodiment can prevent the hinged door 4 from opening outward due to an inappropriate unlocking operation due to mischief or the like from the outside of the room 1.
Further, it is necessary to lift the door end side portion of the main body 108 against the gravity in the second stage of the unlocking operation, which contributes to concealing that the second stage operation is possible.

  Moreover, in the case of the hinged door 4, the person who is in the room 1 can put the weight to prevent the inner door from being opened. On the other hand, when the door is the outer door, pull the hinged door to prevent the door from being opened. May not be easy. In this respect, the locking device 9A of the present embodiment always moves the slide bolt 132 in a state restricted to the inner opening before allowing the hinged door 4 to be opened outward, so that a person in the room 1 can move. It is possible to give a grace time until resistance to an inappropriate unlocking operation from the outside of the room 1.

  Furthermore, in the lock device 9A of the present embodiment, the first and second steps of the unlocking operation are continuously performed by rotating the key 140 in the same direction. For the operator who knows that the operation at the stage is necessary, the hinged door 4 can be quickly opened outward.

  In the locking device 9A of the present embodiment, the first stage of the unlocking operation is a normal linear movement of the slide bolt 132, and the second stage of the unlocking operation is the rotational movement of the guide portion 111 with respect to the mounting plate 102. Therefore, the base 101 of the lock device 9A can be reduced in size as compared with the case where the normal unlocking and the outer opening allowance are continuously performed only by the linear movement of the slide bolt 132.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

  For example, in the second embodiment, the state in which the lock device 9A is attached to the hinged door 4 on the right side when viewed from the outside of the room 1 is shown. The locking device 9A of the second embodiment may be attached to the hinged door 4 on the left side. In this case, the lock device 9A may have an inverted structure with respect to the structure shown in the second embodiment.

  In the above embodiment, an example in which the opening / closing direction restricting portion 116 is arranged on the guide portion 111 is shown, but means for abutting the panel 3 and restricting the hinged door 4 to be inwardly open is provided on the slide bolt 132. It may be done.

  In addition, the design change etc. with respect to the said specific structure are not limited to the said matter.
