Description

  The present invention is based on the locking means from the outside of the room in an emergency, such as in a toilet booth or the like, when a user falls down on the indoor side of a rotary door such as an open door locked by a locking means such as a latch or a slide bolt. The present invention relates to a pivoting door emergency unlocking system for avoiding locking and opening a pivoting door.

  Conventionally, the lock means attached to the rotary door in a toilet booth or the like has used a locking lock that rotates and locks the lock lever, a slide bolt that slides and unlocks linearly, etc. Is installed on the indoor side of the end of the hand side of the door, and on the opposite outdoor side, an indicator that displays the door's locked / unlocked state is arranged outside, and the door is placed between the body and the indicator. Generally, the display type is sandwiched and connected. (See Patent Documents 1 and 2).

  This type of display-type locking means is installed on the display unit so that it can be unlocked even from the outside of the toilet, in case of an emergency, such as when the user falls down inside the locked door. For example, it has a structure including an unlocking operation portion that is interlocked with the lock lever, for example, slotted on the front side. Therefore, at the time of emergency unlocking, lock the lock lever by rotating or sliding the lock lever to the unlocking position by locking a tool such as a coin or screwdriver to the slit of the unlocking operation unit, etc. The means can be easily unlocked.

  By the way, in a toilet booth of a hotel or the like, as shown in FIG. 17, for example, as shown in FIG. 17, a panel-shaped opening door 1 and a door frame 2 between them are arranged in series. It is formed with the door structure 3 assembled so that the whole becomes flush. However, in the display-type lock means with a display, a number of the displays 4 protrude from the outside plate surface of the door structure 3, and the protrusions are visually unsightly and the toilet of a hotel where the aesthetic appearance is important. There was a problem that it was not preferable at booths.

  Therefore, recently, a pivoting door installed in a toilet booth or the like is suspended in a door frame using, for example, a well-known gravity hinge, and when unlocked, the lock lever is moved to the unlocked position to release the locked state. Then, it automatically rotates (inwardly) to the inside of the room and stops and holds it in a half-opened state with a predetermined opening angle, while when closed, the door rests against the headboard or upper frame of the door frame. The structure that restricts the rotation (outward opening) of the door from the outside makes it possible to understand the locked / unlocked state of the door at a glance from the outside, but does not require a display that causes a loss of aesthetics. A type has been proposed.

Japanese Patent Laid-Open No. 2002-256751 JP 2003-106014 A

  However, conventionally, such a non-display type locking means is not provided with a display device on the outside of the door for the sake of aesthetics. There is no room to install an operation unit for emergency unlocking. Therefore, for example, when an emergency situation occurs, such as when the user falls down on the indoor side of the open door in the locked state, the room is too narrow for rescue, so even if you want to open the door to the outside, the door will open door-to-door. Is restricted and can be opened only inside, but since it is locked by the locking means, it cannot be opened inside. In addition, as described above, the rotary door with the non-display-type locking means has no operation part for emergency unlocking as described above. There was a problem that it could not be opened unless the contact part was removed or the door itself was removed.

  Accordingly, an object of the present invention is to provide a lock means that does not have an emergency operation part for the door on the outside of the room in response to an aesthetic request around the door, and restrict the door from opening to the outside. It is to realize that the pivotable door can be easily opened from the outside without using any tools even when the door is locked from the inside in an emergency.

Therefore, the invention according to claim 1 can be opened both inside and outside by suspending the pivotable door D on the door frame F so as to be rotatable by the hinge portion h on the suspending side as shown in the embodiment shown below. while assembling, the a door structure a plate surface entire outdoor side that assembled so as to flush the panel-shaped said door frame F, and the door D in the closed and arranged in series, the lock lever 15, The door D is unlocked by moving between the locking position for locking the opening and closing of the door D and the unlocking position for releasing the lock from the indoor side, while the operation part for emergency unlocking of the door D is moved to the outdoor side. The fixing member 25 is fixed to the hand side corner portion 38 of the door D adjacent to the locking means B which is not provided in the interior, and the gap x which communicates with the outside of the room, and the stopper 30 is attached to the mounting member 25, and the door D is closed. The door D is in contact with the door frame F and rotates outwardly to open outward. Contact position, Hirakiji comprises a doorstop C formed by connecting movably switchable between retracted position for releasing the outer opening regulation of the door D away from the door frame F, the door structure win In this case, the door contact C is flush with the outdoor side plate surface of the door D and the door frame F when the door D is closed over the hand side corner portion 38 at the lower end of the door D and the end of the door frame F facing it. A recessed portion 44 for receiving the door is formed, and the locking means B fixes the mounting body 20 for movably connecting the lock lever 15 to the inside of the end portion of the door frame F facing the hand side of the door D. When the door D is locked, the lock lever 15 is moved with respect to the attachment body 20 to a locking position straddling between the door D and the door frame F, and the door D opens inwardly. to restrict the, emergency unlocking, the gap stopper 30 of the doorstop from C, the outdoor side The moving switching from the contact position to the retracted position through x, characterized by comprising releasing the outer opening regulation of the door D with.

The invention according to claim 2 is the rotary door emergency unlocking system according to claim 1, for example, as shown in the embodiment shown below, the door stop C is configured so that the door D is closed when the door D is closed. The stopper 30 is detachably hooked on the mounting member 25, and a trigger 35 is detachably engaged with the stopper 30 so that the stopper 30 is held in a contact position in a rotation restricted state. To do.

According to the first aspect of the present invention, since the non-display-type locking means is attached, the toilet door without the emergency unlocking operation part on the outdoor side is locked with the locking means. Even if the user wants to rotate and open to the indoor side in an emergency such as when the user falls down, the door is locked by the locking means and is in the open state, so even if you want to open it to the outside, However, even in such a case, the locking means attaches the mounting body that movably connects the locking lever to the indoor side of the end of the door frame that faces the hand side of the door. be projected on straddling locked position between door and door frame, not the hinder opening outside the opening door, while the gap doorstop that regulates the outer opening of the door now, the stopper, leading the indoor and outdoor the mounting member is fixed to the hand side corner portion of an adjacent door and, its The stopper mounting member from the contact position in contact with the door to regulate to open the outer door frame, movably switched from the door frame into a retracted position outwardly opening regulation is released doors away to the outdoor side Because it is connected, it can be unlocked by a simple external operation that moves the door stopper from the outside of the door to the retracted position away from the door frame through the gap without using any tools around you. The door can be opened outside.

According to the second aspect of the present invention, when the door is closed, when the door is closed, the stopper is detachably hooked to the mounting member, and the trigger is detachably hooked to the stopper so that the stopper is in a rotation restricted state. In order to remove the latch on the mounting member and switch the stopper to the retracted position where the door opening restriction is released, the trigger is attached to the stopper before that. The operation that cancels the state is necessary. By adopting such a configuration that requires two-step operation, for example, even if the cleaning tool hits lightly accidentally during cleaning, the door stopper easily moves and cuts. It is possible to prevent the door from being accidentally opened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 (a) is a perspective view showing a door structure to which the rotary door emergency unlocking system of the present invention is applied in a closed state, and FIG. FIG. 2 is a front view showing the door structure as viewed from the outdoor side in a state where the door is closed and locked. The door structure indicated by symbol A in the figure is a door installed in a toilet booth, for example, and the locking means B and the door stop C constitute the rotary door emergency unlocking system of the present invention. Yes.

  The door structure A in the illustrated example includes a plurality of sets of opening doors D and a door frame F for supporting the opening door D, each of which has a panel shape. They are arranged in series with the vertical vertical surfaces facing each other, connected between the door frames F with the caps E and assembled so that the platen on the outdoor side is flush when closed, and between the open door D and the floor surface f In addition, a horizontally long gap x · y is formed between the opening door D and the coping E. When the opening door D is assembled to be able to open both inside and outside by pivoting on the door frame F so as to be able to rotate forward and backward by a hinge part h made of a well-known gravity hinge, the opening door D is unlocked by the locking means B when opened. After being automatically rotated (inwardly opened) to the indoor side, it is stopped and held in a half-open state at a predetermined opening angle.

  The lock means B is a non-display-type lock means that includes only the metal lock lever 15 and the resin attachment body 20 and does not include a display that displays the unlocked / unlocked state of the opening door D on the outdoor side.

  As shown in FIGS. 3 and 4, the lock lever 15 is formed in a substantially groove shape as a whole, and particularly has an engagement piece 15 a that is bent at an opening edge of the groove portion so as to face each other and bend into a substantially L-shaped cross section. A part of the engaging piece 15a is cut out to provide a bumping step (not shown). The mounting body 20 is divided into a base plate 21 and a stop plate 22. The base plate 21 is provided with a fitting recess 21 a for fitting the stop plate 22 on one side plate surface, and guide grooves along the longitudinal direction on both side surfaces. 21b is recessed, and the stop plate 22 has a pair of elastic pieces 22a extending in an L shape on one end in the length direction.

  Therefore, the locking means B is assembled to the door frame F facing the hand side of the opening door D. That is, the base plate 21 is screwed to the end chamber side of the door frame F facing the hand side of the opening door D, and then the mounting plate 20 is assembled by fitting the stop plate 22 into the fitting recess 21a. Then, the engagement protrusion 15a of the lock lever 15 is engaged with the guide groove 21b, and the lock lever 15 is slid while pressing the elastic piece 22a using a screwdriver or the like, and the control protrusion (not shown) provided on the mounting body 20 is omitted. ) Is set at a slide restricting position located between the abutting steps on the lock lever 15 side. Then, the stop plate 22 is pushed up to the engagement height position between the regulating convex part and the abutting step part by the elastic restoring force of the elastic piece 22a. Thereafter, when the caps 23 are put on both ends of the lock lever 15, the lock means B is assembled as shown in FIG. Therefore, when the lock means B slides the lock lever 15 between the slide restriction ranges where the restriction projections abut against the abutment step, the opening door D is unlocked and unlocked accordingly. That is, the lock lever 15 is moved from the indoor side between a locking position where the opening door D on one side where the restricting convex part abuts against the abutting step part is locked and an unlocking position where the lock on the other side is released. The door D is slid linearly to lock and unlock the door D.

  As shown in FIGS. 5 and 6, the door stop C includes an attachment member 25, a stopper 30, and a trigger 35. The mounting member 25 is formed by bending a slightly vertically long metal plate, and bends at right angles from both ends in the length direction of one side edge of the fixing plate portion 25a and faces each other. It has a pair of support pieces 25b and 25c protruding in the direction. On the fixed plate portion 25a, a hook portion 25d is projected from the corner edge on the upper support piece 25b side in the figure in the upward length direction in the figure, while the corner edge on the lower support piece 25c side is supported on the support piece 25c. The relief recess 25e is formed by cutting out to the arc. The support pieces 25b and 25c are provided with shaft holes 27 and 27 through which the round shaft 26 that is longer than the interval between them is inserted.

  The stopper 30 includes a holder 31 and a pad 32. The holder 31 is formed by bending a slightly vertically long metal plate into a U-shape, and in the upper and lower locking pieces 31a and 31b protruding in opposite directions of the both ends in the figure, shaft holes 33 through which the pivot shaft 26 is inserted into one end side, respectively. 33 is provided, and the other end side is notched to form narrow pad attachment portions 31c and 31c. The locking pieces 31a and 31b are provided with pin holes 29 and 29 into which the connecting pin 28 is fitted between the pad mounting portion 31c and the shaft hole 33. In addition, one locking piece 31a is long in the width direction. A rectangular retaining hole 34 is provided. On the pad mounting portions 31c and 31c, presser convex portions 31d are provided so as to project in directions facing each other. The pad 32 is made of rubber or soft plastic having a cushioning property, and is formed into a slightly vertically long substantially rectangular block shape, and is sandwiched between the pad mounting portions 31c and 31c of the holder 31 with the presser convex portions 31d and 31d being bitten. It is adhered with.

  The trigger 35 is made of metal, and has substantially rectangular plate-like arm pieces 35b and 35c protruding from both ends of a support shaft 35a having a length corresponding to the pivot 26 so as to face each other. On the support shaft 35a, a restricting projection 35d is provided near the lower arm piece 35c in the figure, while the thickness of the locking piece 31b of the stopper 30 is between the restricting projection 35d and the arm piece 35c. The engagement groove 37 is recessed by opening a gap in which the locking piece 31b can be engaged. The restricting protrusion 35d is formed with a fitting concave surface 19 formed of a curved surface matching the peripheral surface shape of the pivot 26 at the tip in the protruding direction. The arm pieces 35b and 35c are provided with pin holes 39 and 39 of the connecting pin 28 corresponding to the pin holes 29 of the holder 31, and a lower arm piece 35c on the lower surface in the drawing has a knob 35e for external operation. Is protruding.

  Therefore, in the door stop C, the locking pieces 31 a and 31 b of the stopper 30 and the arm pieces 35 b and 35 c of the trigger 35 are overlapped, and the connecting pin 28 is inserted into the pin holes 29 and 39, and the trigger 35 is connected to the stopper 30. 28 is pivotally connected using a fulcrum 28 as a fulcrum. Next, the hook portion 25d of the mounting member 25 is hooked on the hooking hole 34 so that the stopper 30 is in a rotation-restricted state and is arranged in a direction perpendicular to the fixed plate portion 25a of the mounting member 25, and then the pivot 26 is mounted. The shaft 30 is inserted into the shaft hole 27 of the member 25 and the shaft hole 33 of the stopper 30, and the stopper 30 is connected to the mounting member 25 so as to be rotatable about the pivot 26 using the E ring 41 and the O ring 42. As shown to (a1) * (a2), it connects so that it can move up and down in the figure along the lower end axial part 26a of the pivot 26 between the lower edge of the pivot 26 and the support piece 25c. Then, the trigger 35 is rotated about the connecting pin 28 in one direction shown by an arrow in the figure to engage the engaging groove 37 with the engaging piece 31b of the stopper 30, while the fitting concave surface 19 of the restricting projection 35d is pivoted on the pivot 26. The trigger 35 is connected to the mounting member 25 in a state in which the stopper 30 is restricted from moving up and down.

  Therefore, the door stop C is a door stop position perpendicular to the fixing plate portion 25 of the mounting member 25 in a state where the hook portion 25d of the mounting member 25 is hooked in the retaining hole 34 and the stopper 30 is restricted from rotating. And the latching piece 31b is engaged with the engagement groove 37 of the trigger 35 so that the vertical movement is also restricted. Therefore, the door stop C holds the knob 35e, rotates the trigger 35 in the other direction indicated by the arrows in FIGS. 6B1 and 6B2, removes the locking piece 31b from the engaging groove 37, and stops by the trigger 35. After releasing the vertical movement restriction state of the stopper 30, the stopper 30 is lowered, and the hook portion 25d of the attachment member 25 is removed from the retaining hole 34 to release the rotation restriction state of the stopper 30. It is structured to be connected to the mounting member 25 so that it can be switched and moved to a retracted position that opens away from the fixed plate portion 25a of the 25 at an obtuse angle.

  Therefore, in the present invention, as shown in FIG. 1, the door structure A spans the hand side corner portion 38 at the lower end of the opening door D and the end portion of the door frame F facing it, as shown in FIG. In accordance with the outer shape of the door stopper C in the assembled state shown in (a2), a door stopper recess 44 including a door-side mounting step 44a and a door frame-side receiving step 44b is formed.

  On the other hand, the door stop C is in the assembled state, that is, the stopper 30 is held at the door stop position in which the hook portion 25d of the mounting member 25 is hooked in the hook hole 34 and the rotation is restricted, and the locking piece 31b is triggered. In the state where the vertical movement is restricted by engaging with the engagement groove 37 of 35, the fixing plate portion 25a of the attachment member 25 is screwed to the end face 43 of the attachment step portion 44a on the door side as shown in FIG. 6 (a1). Then, the pad 32 of the stopper 30 is assembled to the opening door D by projecting from the hand side corner portion 38 toward the receiving step portion 44b of the door frame F with the pad 32 facing the indoor side.

  Now, in the present invention, when using the toilet, when the door D is locked, the door D that has been opened in the half-opened state inside the toilet is closed from the toilet room, and the door frame F side is now closed. The locking lever 15 of the locking means B in the unlocked position slides in the direction of the arrow in FIGS. 1A and 8 with respect to the mounting body 20 and protrudes to the locked position straddling between the opening door D and the door frame F. Then, the door D is locked and restricted from opening inward to the room side. At this time, when the opening door D is closed from the toilet room, the stopper 30 of the door stop C held at the door stop position in the rotation restricted state comes into contact with the receiving step portion 44b of the door frame F via the pad 32 and opens the door D. Is restricted from opening outward to the outdoor side, and thus the opening door D is locked. When the door D is closed, in the door structure A, the door stop C does not protrude and is placed in the door stop recess 44 flush with the outside door surface of the door D and the door frame F. Yes.

  On the other hand, when unlocking the door D, the lock lever 15 in the locked position is slid from the indoor side of the toilet to the unlocked position as shown in FIG. Then, as shown in FIG. 10, the opening door D automatically rotates indoors by the hinge portion h of the gravity hinge, and is held and held in a half-open state at a predetermined opening angle. Even if it does not have the indicator which displays the locking / unlocking state of the opening door on the outdoor side, the opening / closing state of the opening door D can be seen from the outdoor side at a glance, that is, the use state of the toilet can be known. .

  On the other hand, when the door D is to be unlocked from the outside in an emergency such as when the user falls down in the toilet room while the door D is locked by the locking means B, a hand is placed in the gap x between the floor f. First, the trigger 35 of the door C is rotated in the other direction indicated by the arrow in FIG. 7A by picking the knob 35e, and the locking piece 31b is engaged as shown in FIG. 7B. The vertical movement restriction state of the stopper 30 by the trigger 35 is released by removing from the groove 37. Thereafter, the stopper 30 is pulled down, and the hook portion 25d of the mounting member 25 is removed from the retaining hole 34 as shown in FIG. 7C, and the rotation restriction state of the stopper 30 is released, and FIGS. As shown in FIG. 13, the stopper 30 located at the door contact position in contact with the receiving step portion 44 b of the door frame F is switched to a retracted position away from the door frame F to the outdoor side by rotating around the pivot 26. It is moved and the restriction | limiting of the outward opening of the opening door D is cancelled | released, Therefore, the opening door D is unlocked very much.

  Therefore, in the present invention, since the non-display type locking means B is provided as described above, the opening door D having no emergency unlocking operation part on the outdoor side is locked with the locking means B while the toilet door is locked. Even if you want to open the room indoors in an emergency such as when the user falls down, the door D is locked by the locking means B and is in the state of being restricted from opening inside. Even in such a case, the locking means B opens the mounting body 20 that slidably connects the lock lever 15 and opens the end of the door frame F facing the hand side of the door D. Therefore, even if the lock lever 15 protrudes to the locking position across the opening door D and the door frame F, it does not hinder the opening of the opening door D. On the other hand, the opening of the opening door D is now prevented. The controlled door stop C has a gap between the stopper 30 and the floor surface f. The attachment member 25 is fixed to the hand side corner portion 38 of the opening door D adjacent to the door, and the stopper 35 is brought into contact with the receiving step portion 44b of the door frame F to restrict the opening door D from opening outward. Since the contact position is separated from the door frame F to the outdoor side, the door D can be switched to the retracted position where the restriction of the outward opening of the door D is released, so that the outdoor side can be moved without using any personal tools. Therefore, the door D can be opened and opened by a simple external operation by switching and moving the stopper 35 of the door stop C from the door frame F to the retracted position away from the door frame F through the gap x.

  In the illustrated embodiment described above, the lock means B is a slide bolt that locks and unlocks the lock lever 15 by linearly sliding the lock lever 15 between the lock position and the unlock position. Instead, for example, as shown in the following illustrated embodiment, the lock lever may be a lock and lock that rotates and locks between a locking position and an unlocking position. In the following illustrated embodiment in which the locking means is a hooking lock, the same components as those in the illustrated embodiment will be described with the same reference numerals.

  As shown in FIGS. 14, 15 and 16, the rotary door emergency unlocking system of the other example shown in the figure includes a door structure A installed in a toilet booth, a locking means B 'for a locking lock, and an opening. It is comprised by the door stop C assembled | attached to the hand side corner | angular part 38 of the door D. FIG.

  The locking means B 'for locking the lock comprises a lock lever 40, a mounting body 45, and a lever receiver 50, and is a non-display type lock that does not have a display for displaying the unlocked / unlocked state of the opening door D on the outdoor side. Means. The lock lever 40 includes a resin-made circular cap-shaped support cover 40a and a metal rod-shaped lever main body 40b. The lever main body 40b is inserted in the radial direction of the support cover 40a and integrated by insert molding. The attachment body 45 is formed in a metal circular seat shape having a plurality of screw insertion holes. On the other hand, the lever receiver 50 includes a mounting seat 50a in which a decorative cap is put on a fixed plate piece, and a round shaft-shaped receiving portion 50b that stands upright at one end of the mounting seat 50a.

  In the other example shown in the figure, the locking means B ′ rotates by attaching the support cover 40a to the attachment body 45 after screwing the attachment body 45 to the inner side of the end portion of the door frame F facing the hand side of the opening door D. The lock lever 40 is fitted to the mounting body 45 so that the lever body 40b can be rotated in an angular range between an unlocked position where the lever body 40b stands vertically and a locked position where the lever body 40 falls horizontally. It becomes. On the other hand, the lever receiver 50 is fixed to the inside of the end portion of the door D on the hand side at the height position where the lever main body 40b is engaged with the receiving portion 50b when the lock lever 40 is in the locking position.

  In the other example shown in the figure, when the door D is locked when the toilet is used, the door D that has been opened halfway to the toilet room side is closed from the toilet room, and then the door frame F side is opened. The lock lever 40 erected in the locked position is rotated with respect to the attachment body 45 in the direction of the arrow in FIG. 14, and the lever main body 40 b is locked to the receiving portion 50 b of the lever receiver 50 to be between the opening door D and the door frame F. The door D is tilted to the straddling locking position to lock the door D and restricted from opening inward to the room side. At this time, when the opening door D is closed from the toilet room, the stopper 30 of the door stop C held at the door stop position in the rotation restricted state comes into contact with the receiving step portion 44b of the door frame F via the pad 32 and opens the door D. Is restricted from opening outward to the outdoor side, and thus the opening door D is locked. On the other hand, when unlocking the opening door D, from the toilet room side, the lock lever 40 in the locking position is rotated to the unlocking position as shown in FIG. To do. Then, the opening door D automatically rotates indoors by the hinge part h of the gravity hinge, and is held and held in a half-open state at a predetermined opening angle.

  On the other hand, when the user opens the door D from the outside in an emergency such as when the user falls down while the door D is locked by the locking means B ′, the door D is placed between the floor f. As shown in FIGS. 7 (a), (b), and (c), the gap 35 is first turned, and the trigger 35 is rotated by holding the knob 35e of the trigger 35 provided for the door stop C. The stop piece 31b is removed from the engagement groove 37, and the vertical movement restriction state of the stopper 30 by the trigger 35 is released. Thereafter, the stopper 30 is pulled down, the hook portion 25d of the mounting member 25 is removed from the retaining hole 34, the rotation restriction state of the stopper 30 is released, and the door contact position that contacts the receiving step portion 44b of the door frame F is reached. As shown in FIG. 16, the stopper 30 is rotated about the pivot 26 and moved to the retracted position away from the door frame F to the outdoor side to release the restriction on the opening of the opening door D. Then, the door D is unlocked.
