Description

Lock device and door and window

Technical Field

The invention relates to a lock device and a door and window.

Background

As a lock device provided in a door or window, for example, there is a lock device including a lock pin provided in a housing and a lock unit provided in a door or window sash. The lock unit is provided with a trigger member which releases the locked state when the lock unit is disposed at the unlocked position, and the handle of the door sash is connected to the trigger member. In this lock device, when the door sash is closed with respect to the housing, the lock unit is in a locked state in a state where the lock pin enters the lock unit. When the locking unit is in the locked state, the movement of the locking pin relative to the locking unit is prevented, thereby maintaining the closed state of the door and window sash relative to the frame. When the handle of the door or window sash is opened from the above state, the trigger member is disposed at the unlock position, and the lock unit is thereby placed in the unlock state. Thereby, the movement of the lock pin relative to the lock unit is allowed, and therefore the door sash can be opened relative to the frame (for example, see patent document 1).

Disclosure of Invention

However, sometimes a plurality of lock devices are required in the window and door in order to maintain a reliably closed state between the frame and the window and door sash. For example, in a window or door provided in a strong wind area, a plurality of lock devices are provided between the frame and the window or door, thereby preventing the window or door from being accidentally opened. In addition, in the case of a large window, it is preferable to provide a plurality of lock devices between the frame and the door sash in order to maintain the door sash in a reliably closed state.

However, in a door or window provided with a plurality of lock devices, if all the trigger members are not moved to the unlocking position, the door or window cannot be opened. Therefore, when opening the door sash, it is necessary to open the plurality of handles, which may complicate the opening operation of the door sash.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a lock device and a door window that can prevent the opening operation of the door sash from becoming complicated even when a plurality of door windows are provided.

In order to achieve the above object, a lock device according to the present invention includes: a locking unit provided to one of the frame and the door/window sash through the unit body; and a lock pin provided on the other of the housing and the door sash, wherein the lock unit is in a locked state when the door sash is closed to prevent movement of the lock pin with respect to the unit body and maintain the door sash in a closed state, and wherein the locked state of the lock unit is released to allow movement of the lock pin with respect to the unit body when a handle provided on the door sash is opened from a normal position, the lock device further comprising: and an operating member that is disposed in the door/window sash in a state interlocked with the opening operation of the handle, wherein a trigger member that releases the locked state when the locking unit is disposed in the unlocked position is disposed in the locking unit, and wherein the operating member is provided with a release member that moves the trigger member to the unlocked position when the handle is opened in a state in which the door/window sash is closed.

According to the present invention, the operating member is interlocked by the opening operation of the handle, and the trigger member of the lock unit is moved to the unlock position by the release member provided to the operating member. Therefore, even when the door window is provided with the lock units, if the release members are provided in the common operating member and the lock units, respectively, the trigger members of the lock units can be simultaneously arranged at the unlock position by performing the opening operation on 1 handle, and the door window can be opened without requiring a complicated opening operation.

Detailed Description

Hereinafter, preferred embodiments of a lock device and a door window according to the present invention will be described in detail with reference to the accompanying drawings. For convenience, the following description will be made using terms such as the depth direction and the front view direction. The depth direction is a direction along the depth of the window and door as indicated by an arrow a in the drawing. The surface along the depth direction is sometimes referred to as a depth surface. The front view direction refers to a vertical direction perpendicular to the depth direction for a member extending in the horizontal direction, such as an upper frame or an upper frame described later. A member extending in the vertical direction, such as a vertical frame or a vertical frame, is referred to as a front view plane direction as a direction perpendicular to the depth direction and horizontal. The surface along the main viewing surface direction is sometimes referred to as a main viewing surface.

Fig. 1, 2A and 2B are views illustrating a door or window to which a lock device according to an embodiment of the present invention is applied. The door window exemplified here includes a frame 10 and a door sash 20, and is a so-called slide-shaft casement window configured such that the door sash 20 can be opened to the outside of the room with respect to the frame 10. The frame 10 is constituted by a peripheral frame composed of an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14. The door sash 20 is configured by attaching an upper frame 22, a lower frame 23, and left and right vertical frames 24 and 25 to the periphery of a rectangular surface member 21. Examples of the frames 11, 12, 13, 14 constituting the frame body 10 and the frames 22, 23, 24, 25 constituting the door sash 20 include composite type frames and frames, and as shown by the vertical frame 13 and the vertical frame 24 in fig. 2A and 2B, the composite type frames and frames include outdoor side portions 13A, 24A each formed of an extruded material of a metal such as an aluminum alloy; and indoor inner portions 13B, 24B formed of an extruded profile of resin. However, the frame and the frame are not limited to the composite frame and the frame, and may be formed of a single metal or a single resin. In the example shown in the figure, the vertical frame 24 on the right side in fig. 1 is a door sash front end, and the vertical frame 24 at the door sash front end projects outdoors with respect to the frame 10. In this door/window, the handle 30, the operating member 40, and the plurality of lock pins 50 are provided to the vertical frame 24 at the front end of the door leaf 20, while the plurality of lock units 60 are provided to the vertical side frame 13 of the frame 10 corresponding to the vertical frame 24 at the front end of the door leaf.

As shown in fig. 2A, 2B, 3A, and 3B, the handle 30 includes a handle body 31 and an operating member 32, and is attached to a portion of the front surface 24a facing the interior of the vertical frame 24 corresponding to the surface material receiving groove 24B via the handle body 31. The surface material receiving groove 24B is a recess for receiving an edge portion of the surface material 21, and is configured by providing support arm portions 24c facing each other toward an inner peripheral side from portions on the inner peripheral side constituting the outer side portion 24A on the outdoor side and the inner side portion 24B on the indoor side, respectively. The inner bottom wall 24d of the face material receiving groove 24b is provided on the outer side portion 24A. The operation member 32 is supported by the handle body 31 so as to be rotatable about an operation axis extending vertically with respect to the handle body 31 and so as to be in a state in which relative movement in the vertical direction is restricted.

The handle body 31 of the handle 30 is provided with a slider 33 and a return spring 34. The slider 33 is supported to be movable up and down with respect to the handle body 31, and includes a follower inclined surface 33a and a coupling hook 33b. The driven inclined surface 33a is a downward flat surface provided at the lower end of the slider 33, and is inclined so as to gradually rise toward the indoor side. The connecting hook 33B protrudes from the slider 33 to the outside and then bends downward, and passes through the handle body 31 and the support arm portion 24c of the inner portion 24B to protrude into the surface material receiving groove 24B. The return spring 34 is a compression coil spring located between the handle main body 31 and the slider 33, and applies a force to the slider 33 that is always directed downward with respect to the handle main body 31.

The operating member 32 of the handle 30 is provided with an elevation driving portion 32a. The elevation driving portion 32a is disposed such that: projects toward the slider 33 and approaches or separates from the slider 33 when the operating member 32 is rotated with respect to the handle main body 31, and a front end portion thereof has a driving inclined surface 32b. The driving inclined surface 32b is a flat surface inclined so as to gradually face downward toward the outside of the room. The driving inclined surface 32b is configured to: as shown in fig. 3A, when the upward driving portion 32a is disposed at the farthest position from the slider 33, the lowermost edge portion thereof is positioned below the uppermost edge portion of the follower inclined surface 33A of the slider 33, and as shown in fig. 3B, when the upward driving portion 32a approaches the slider 33, it abuts against the follower inclined surface 33A. That is, when no operating force is applied to the operating member 32, the handle 30 maintains the slider 33 at the lowermost position by the return spring 34, as shown in fig. 3A, and thus maintains the state in which the lift driving portion 32a is disposed at the farthest position from the slider 33 (the normal position of the handle 30) due to the tilting action of the driven inclined surface 33A and the driving inclined surface 32b which are in contact with each other. When the operating member 32 is rotated from the normal position (the opening operation of the handle 30) to the outside of the room with respect to the handle main body 31, as shown in fig. 3B, the upward driving portion 32a moves so as to approach the slider 33, and the slider 33 moves upward against the biasing force of the return spring 34 by the tilting action of the driven inclined surface 33a and the driving inclined surface 32B which are in contact with each other. When the operating force on the operating member 32 is removed from this state, as shown in fig. 3A, the slider 33 moves downward by the biasing force of the return spring 34, and the upward driving portion 32a moves away from the slider 33 by the tilting action of the driven inclined surface 33A and the driving inclined surface 32b which are in contact with each other, so that the operating member 32 returns to the normal position.

As shown in fig. 2A to 5B, the operating member 40 is an elongated member extending in the vertical direction and having a rectangular cross section, and is disposed on the depth surface 24e on the outer peripheral side of the vertical frame 24 in a vertically movable state. The working member 40 is provided with a connection hole 41 at a portion corresponding to the attachment position of the handle 30. The connection hole 41 is a substantially rectangular long hole that penetrates in the front view plane direction and extends vertically. The connection piece 42a of the connection member 42 is fitted into the connection hole 41. The connecting member 42 is used to transmit the movement of the slider 33 provided to the handle 30 to the operating member 40. In the present embodiment, the connection member 42 is configured to include a front view direction extending portion 42B, a depth direction extending portion 42c, and a connection piece 42a, the front view direction extending portion 42B is disposed along the support arm portion 24c of the inner portion 24B in the surface material receiving groove 24B of the vertical frame 24, the depth direction extending portion 42c is bent toward the outdoor side from the outer peripheral side edge portion of the front view direction extending portion 42B and is disposed along the inner bottom wall 24d in the surface material receiving groove 24B, and the connection piece 42a extends toward the outer peripheral side in the front view direction from the central portion of the outdoor side edge portion of the depth direction extending portion 42 c. The connecting piece 42a projects outward from the depth surface 24e on the outer peripheral side of the vertical frame 24 through a notch portion, not shown, provided in the vertical frame 24, and the projecting end portion thereof is fitted into the connecting hole 41 of the operating member 40. The extended portion 42b of the coupling member 42 in the front-view direction is provided with a notch portion 42d at its central portion for coupling, and is coupled to the coupling hook 33b of the slider 33 via the notch portion 42 d. The connecting member 42 is supported so as to be movable up and down via an operation guide 43 connected to the handle body 31. The operation guide 43 includes a main-view-surface-direction guide portion 43a and a depth-direction guide portion 43b, the main-view-surface-direction guide portion 43a extends along the main-view-surface-direction extending portion 42b of the connection member 42, and the depth-direction guide portion 43b extends along the depth-direction extending portion 42c of the connection member 42 by extending from the outer peripheral edge portion of the main-view-surface-direction guide portion 43a toward the outside of the room, whereby the operation guide 43 is attached to the handle main body 31 via the main-view-surface-direction guide portion 43 a. A slide guide pin 44 is provided vertically on the depth direction guide portion 43 b. The slide guide pin 44 is inserted through a long hole 42e formed in the depth direction extending portion 42c, and supports the connection member 42 so as to be movable up and down with respect to the operation guide 43.

When the operating member 32 of the handle 30 is in the normal position, the operating member 40 having the above-described configuration is disposed in the standby position with respect to the vertical frame 24. When the operation member 32 of the handle 30 is opened from this state, the upward movement of the slider 33 is transmitted to the working member 40 via the connecting member 42, and the working member 40 moves upward with respect to the vertical frame 24. When the operating force to the handle 30 is removed, the operating member 40 moves downward with the downward movement of the slider 33, and returns to the standby position.

The lock pins 50 are arranged in parallel with each other along the longitudinal direction of the vertical frame 24 at portions closer to the indoor side than the working member 40 on the depth surface 24e on the outer peripheral side of the vertical frame 24, and protrude from the depth surface 24e toward the outer peripheral side. In the present embodiment, the lock pin 50 has a head 50a with a large diameter at its protruding end, and is attached to the vertical frame 24 via the slide guide member 51. The slide guide member 51 is a crank-shaped member that is curved so as to cover the side surface and the outer surface of the working member 40 from the depth surface of the vertical frame 24, and guides the working member 40 to move up and down with respect to the vertical frame 24. The lock pin 50 is provided at a portion of each slide guide member 51 attached to the vertical frame 24. As is apparent from fig. 2A and 2B, in the vertical frame 24 of the present embodiment, a cover arm portion 24f is provided at an edge portion on the outdoor side. The cover arm portion 24f projects further toward the outer peripheral side than the lock pin 50, and thereby the lock pin 50 and the operating member 40 can be prevented from being directly peeped from the outdoor side when the door/window sash 20 is in the closed state.

The locking means 60 controls opening and closing of the door sash 20 with respect to the frame body 10 by the locking pin 50 of the vertical frame 24, and is provided in parallel with each other in the longitudinal direction of the vertical frame 13 in the same manner as the locking pin. As shown in fig. 2A, 2B, and 6A to 8B, each locking unit 60 includes a unit body 61. The unit main body 61 is configured to have mounting plate portions 61b at both upper and lower end portions of a substantially rectangular substrate portion 61a. The mounting plate portion 61b is bent in the same direction from both upper and lower edge portions of the base plate portion 61a at substantially right angles, and then bent at substantially right angles in directions away from each other to form an L-shape. The unit main body 61 is attached to the inner circumferential side depth surface 13a of the vertical frame 13 by the attachment plate portion 61b in a state where the base plate portion 61a protrudes toward the vertical frame 24. The protruding dimension of the base plate portion 61a from the depth surface 13a of the vertical frame 13 is set so that the protruding end portion of the lock pin 50 is positioned between the base plate portion 61a and the depth surface 13a of the vertical frame 13 when the door sash 20 is closed. A pin insertion groove 62 and a trigger insertion groove 63 are formed in the base plate portion 61a of the unit main body 61. The pin insertion groove 62 extends in the depth direction from a substantially central portion of the substrate portion 61a toward the outdoor side, and is open at an edge portion located on the outdoor side of the substrate portion 61a. The trigger member insertion groove 63 is formed in an arc shape having a curvature center at the rotation axis of a lock member 64 described later, and is a notch with both ends closed, at a portion above the pin insertion groove 62. In the present embodiment, the trigger insertion groove 63 is formed so as to be curved downward as it approaches the outdoor side. The base plate portion 61a of the unit main body 61 is provided with a hook member 65, a lock member 64, and an opening maintaining member 66 at a portion facing the vertical side frame 13.

The hook member 65 is integrally formed with a cylindrical support cylinder portion 65a, a lock arm portion 65b and a release arm portion 65c extending from the outer peripheral surface of the support cylinder portion 65a, and an engagement portion 65d provided on the end surface of the support cylinder portion 65a, and is arranged to be rotatable about the axis of the hook support shaft 65e by inserting the hook support shaft 65e provided on the base plate portion 61a of the unit main body 61 on the indoor side and the upper side of the pin entry groove 62 into the support cylinder portion 65 a. The lock arm portion 65b projects radially from the outer peripheral surface of the support cylinder portion 65a, and then the projecting end portion is bent substantially at a right angle. Specifically, as shown in fig. 7A, the lock arm portion 65b is configured to be disposed above the pin entry groove 62 of the base plate portion 61a when extending substantially horizontally from the hook support shaft 65e toward the outdoor side, and the bent tip end portion thereof crosses the opening end portion of the pin entry groove 62 (the engagement position of the hook member 65). As shown in fig. 8A, when the tip end portion of the lock arm portion 65b is rotated upward, the opening end portion of the pin insertion groove 62 can be opened (the non-engagement position of the hook member 65). As shown in fig. 7A, when the hook member 65 is disposed at the engagement position, the release arm portion 65c protrudes upward and is bent from a portion of the outer peripheral surface of the support tube portion 65a that is slightly outside the room than the hook support shaft 65e, and is inclined upward so as to gradually face the outside of the room. The tip end portion of the release arm portion 65c is configured to cover the upper portion of the trigger insertion groove 63 formed in the substrate portion 61a when the hook member 65 is disposed at the engagement position. The engaging portion 65d protrudes from the end surface of the support cylindrical portion 65a facing the vertical frame 13 toward the vertical frame 13, and has engaging teeth 65f at the end portion of the tip when the hook member 65 rotates toward the engaging position.

The lock member 64 is in the form of a flat plate having an oblong outer shape and is rotatably supported by the base plate portion 61a via a lock support shaft 64a provided at one end portion. The lock support shaft 64a is provided at a position constituting the center of curvature of the trigger member insertion groove 63 having an arc shape, and is positioned vertically above the lower end of the trigger member insertion groove 63. A trigger member 67 is provided at the other end of the lock member 64. The trigger member 67 has a pin shape with a circular cross section, and a tip end portion thereof protrudes outward from the trigger member insertion groove 63 through the base plate portion 61a of the unit body 61. As shown in fig. 7A, when the trigger member 67 is disposed at the lower end of the trigger member insertion groove 63 in a state where the hook member 65 is disposed at the engaged position, the other end of the lock member 64 abuts against the upper surface of the lock arm portion 65b, and the hook member 65 can be prevented from rotating to the disengaged position. As shown in fig. 8A, when the lock member 64 is rotated so that the trigger member 67 moves upward along the trigger member insertion groove 63 from this state, the other end portion of the lock member 64 abuts against the release arm portion 65c, and thereafter, the lock member 64 is rotated so that the hook member 65 rotates toward the non-engagement position. In a state where the trigger member 67 is disposed above the trigger member insertion groove 63 (the unlock position of the trigger member 67), the hook member 65 is disposed at the non-engagement position. The distance of the trigger member 67 that moves up and down is set to be substantially equal to the upward movement distance of the operating member 40 when the operating member 32 of the handle 30 is opened.

As can be seen, a lock spring 68 is attached to the hook member 65 and the lock member 64. The lock spring 68 biases the hook member 65 to be maintained at the engagement position, and biases the trigger member 67 provided on the lock member 64 to be maintained at the lower end of the trigger member insertion groove 63 (the lock position of the trigger member 67). Specifically, the one end portion 68b of the lock spring 68 extends from the spring support shaft 68a so as to be engaged with the lock member 64 via the lock support shaft 64a, and the spring support shaft 68a is provided on the base plate portion 61a on the indoor side of the lock support shaft 64 a. The other end portion 68c of the lock spring 68 extends from the spring support shaft 68a to engage with the lock arm portion 65b of the hook member 65 via the hook support shaft 65 e.

The opening maintaining member 66 is disposed below the base plate portion 61a by a 1 st elevation guide pin 70 and a 2 nd elevation guide pin 71 provided in the unit main body 61, and is vertically movable with respect to the unit main body 61. The 1 st elevation guide pin 70 is provided to protrude from the base plate portion 61a toward the vertical frame 13, and penetrates through the vertically elongated guide groove 66a of the opening maintaining member 66. The 2 nd elevation guide pin 71 protrudes upward from the lower mounting plate portion 61b, and an upper end portion thereof is slidably fitted into a slide hole (not shown) provided in the opening maintaining member 66. The opening maintaining member 66 is provided with an engaging projection 66b and a pressing inclined surface 66c. The engaging projection 66b projects upward from a portion of the upper end of the opening maintaining member 66 corresponding to the engaging portion 65d of the hook member 65. As shown in fig. 8A, when the opening maintaining member 66 is disposed above the unit main body 61 in a state where the hook member 65 is disposed at the non-engagement position, the engaging projection 66b is in a state of facing the end surface of the support cylindrical portion 65 a. From this state, when the hook member 65 is rotated toward the engagement position as shown in fig. 7A, the engagement teeth 65f of the engagement portion 65d abut against each other, and the hook member 65 is prevented from rotating toward the engagement position. That is, as shown in fig. 8A, when the release maintaining member 66 moves upward in a state where the hook member 65 is disposed at the non-engagement position, the engagement portion 65d engages with the engagement protrusion 66b, and the hook member 65 is maintained at the non-engagement position against the urging force of the lock spring 68. In the illustrated example, the engaging projection 66b is formed in a step shape, and can maintain the hook member 65 at a plurality of positions between the non-engagement position and the engagement position. The pressing inclined surface 66c is an inclined surface formed at an upper corner portion located on the outdoor side of the opening maintaining member 66, and is inclined so as to be gradually downward toward the outdoor side. The pressing inclined surface 66c is configured to be located below the lock pin 50 inserted into the pin insertion groove 62 of the base plate portion 61a when the opening maintaining member 66 is disposed below, and to protrude into the pin insertion groove 62 and come into contact with the lock pin 50 inserted into the pin insertion groove 62 when the opening maintaining member 66 is disposed above. An opening maintaining spring 72 for applying an upward force to the opening maintaining member 66 is provided between the opening maintaining member 66 and the unit main body 61 so as to be wound around the 2 nd elevation guide pin 71.

The lock unit 60 having the above-described configuration is attached to the vertical frame 13 via the unit main body 61 in a state in which each lock pin 50 provided to the door sash 20 can enter the pin entry groove 62 formed in the base plate portion 61a when the door sash 20 is closed with respect to the frame 10.

As shown in fig. 2A, 2B, 4A, 4B, 5A, 5B, 9A, and 9B, in addition, a release member 80 is provided on the operating member 40 provided to the door sash 20 corresponding to the number of the locking units 60. When the hook member 65 of each locking unit 60 is disposed at the engagement position and the trigger member 67 is positioned at the lower end of the trigger member insertion groove 63 in the closed state of the door sash 20, the release member 80 is disposed below the trigger member 67 protruding from the unit body 61, and when the operating member 40 moves upward, it presses the trigger member 67 upward toward the unlock position. A curved concave surface 80a that gradually becomes lower toward the indoor side is formed in a portion of the release member 80 that abuts against the trigger member 67.

Next, the operation of opening or closing the door sash 20 of the door window will be described, and the characteristic portions of the present invention will be described in detail. In the present case, assuming that the door sash 20 is in an open state with respect to the frame 10, as shown in fig. 8A and 8B, the hook member 65 of the lock unit 60 is disposed at the non-engagement position, and the engagement portion 65d is engaged with the engagement projection 66B of the opening maintaining member 66 located above, so that the hook member 65 is maintained at the non-engagement position against the urging force of the lock spring 68.

When the door sash 20 is moved in the closing direction with respect to the housing 10 from this state, the lock pin 50 inserted into the pin insertion groove 62 of the unit body 61 abuts against the pressing inclined surface 66c of the opening maintaining member 66. As a result, as shown in fig. 7A and 7B, the opening maintaining member 66 moves downward relative to the unit main body 61 so that the engagement state between the engaging portion 65d of the hook member 65 and the engaging protrusion 66B of the opening maintaining member 66 is released, and the hook member 65 moves toward the engagement position by the biasing force of the lock spring 68, and the other end portion of the lock member 64 comes into contact with the upper surface of the lock arm portion 65B. As a result, the state in which the bent tip end portion of the lock arm portion 65b is disposed so as to cross the opening end portion of the pin entry groove 62 can be maintained, and the movement of the lock pin 50 from the pin entry groove 62 in the disengaging direction can be prevented, whereby the state in which the door sash 20 is closed with respect to the frame 10 can be maintained. As shown in fig. 2A, in a state where the door sash 20 is closed with respect to the frame body 10, the seal member 90 provided to the vertical frame 13 is pressure-bonded to the cover arm portion 24f of the vertical frame 24 without interposing an object therebetween, and the seal portion 91 integrally formed with the inner portion 13B of the vertical frame 13 is pressure-bonded to the indoor-facing front surface 24a of the vertical frame 24 without interposing an object therebetween, so that a problem of water tightness or air tightness between the vertical frame 13 and the vertical frame 24 is not caused.

On the other hand, when the operating member 32 of the handle 30 is opened from the above state, as shown in fig. 9A and 9B, the operating member 40 moves upward, the plurality of release members 80 move upward, and the trigger members 67 provided in the respective lock units 60 move upward toward the unlocking position along the trigger member insertion grooves 63 at the same time. When the trigger member 67 is disposed at the unlock position, the rotating lock member 64 is separated from the upper surface of the lock arm portion 65b and brought into contact with the release arm portion 65c, whereby the hook member 65 is moved to the disengaged position against the biasing force of the lock spring 68. Therefore, the opening end of the pin insertion groove 62 is opened, and the lock pin 50 is allowed to move in the disengaging direction, whereby the door sash 20 can be opened with respect to the frame 10. At this time, when the lock pin 50 is disengaged from the pin entry groove 62, the release maintaining member 66 moves upward by the biasing force of the release maintaining spring 72, and the engaging portion 65d of the hook member 65 is again engaged with the engaging projection 66b of the release maintaining member 66, so that the hook member 65 is maintained at the non-engagement position. Therefore, when the opened door sash 20 is closed again, the locking pin 50 enters the pin entering groove 62 of the base plate portion 61a, and the hook member 65 is positioned at the engagement position as in the prior art, so that the locked state between the housing 10 and the door sash 20 can be maintained without performing the locking operation.

As described above, according to the door/window, when the door sash 20 is closed with respect to the frame 10, the plurality of locking pins 50 provided to the door sash 20 can be maintained in the state of being inserted into the corresponding locking units 60 without any locking operation. Therefore, for example, when the door or window is installed in a strong wind area or when the size of the door or window is large, the door or window sash 20 can be maintained in the reliably closed state without requiring a complicated operation, and the door or window sash 20 is not accidentally opened. On the other hand, when the only handle 30 provided in the door 20 is operated to open the door 20 from the closed state of the door 20, the locked state of all the locking units 60 is simultaneously released (unlocked state), and the door 20 can be opened without requiring a complicated operation.
