Assembly part

Technical Field

The present invention relates to a fitting provided with a lock member for locking a movable door or window provided slidably in a door or window frame, or with a door or window side lock for locking a door or window side of the movable door or window.

Background

A mount having a lock member for locking a movable door or window provided in a door or window frame so as to be capable of being opened and closed slidably is known, and for example, a mount having a crescent lock for locking a double sliding door is known. The crescent lock provided in such a fitting is locked by, for example: one of the movable doors and windows is provided with a metal base, the other movable door and window is provided with an ear portion of a crescent lock which is turned and then locked with the metal base, and the one movable door and window and the other movable door and window are brought close to each other and locked by turning the ear portion and locking with the metal base (for example, see patent document 1).

Further, a door/window edge lock for locking a sliding door at a door/window edge side of a moving door/window has been known, for example, as follows: a transverse-shaft-shaped stopper member fixed to a door frame of a moving door/window and having a thickness direction of the moving door/window as an axis is provided, and a window frame has a locking portion which connects a lock member rotatable in a longitudinal direction by a 1 st shaft of the transverse-shaft shape and a restricting member rotatable in the longitudinal direction by a 2 nd shaft of the transverse-shaft shape, by a spring member. In the locking device, the 1 st shaft is arranged above the 2 nd shaft, and when the movable door and window is closed, the stop member enters between the 1 st shaft and the 2 nd shaft and contacts with the lock member to rotate the lock member; by the rotation of the lock member, the stopper member is stopped at a position closer to the sliding door/window side than the 1 st shaft in the groove provided in the lock member. At this time, the spring member disposed on the opposite side of the 1 st shaft to the side of the movable door window expands with the rotation of the lock member, and rotates the restricting member. As a result, the stopper portion, which restricts the rotation of the lock member relative to the restricting member by the rotation of the restricting member, is stopped, and the lock member is pressed in the vertical direction to lock the lock member. A lever for releasing the locked state of the restricting member and the lock member protrudes on the opposite side of the movable door window side than the spring member, and the locked state of the restricting member and the lock member is released by moving the lever downward (see, for example, patent document 2).

Disclosure of Invention

The lock part for locking the movable door and window has a door and window side lock which is arranged at the door and window side of the movable door and window and locks the middle of the vertical frame. Since the door/window edge lock has a small effect of bringing the movable door/window closer in the depth direction by the locking operation like a crescent lock, there is a problem that the locking may not be performed when the position between the jamb and the vertical frame is not appropriate when the movable door/window is closed.

In the conventional lock device, the lock member that rotates about the 1 st axis is disposed above the stopper member that enters when the movable door window is closed, and the restricting member that rotates about the 2 nd axis is disposed below the stopper member, so that a large space is required in the vertical direction. Further, the lever for releasing the locked state of the restricting member and the lock member extends on the opposite side of the position where the stopper member is stopped in the groove of the lock member with respect to the 1 st and 2 nd shafts, and therefore, a space larger than the apparent direction is required. For this reason, the jamb or sash provided with the lock device becomes large, and the installation space of the door or window requiring a larger installation space becomes narrow.

In view of these problems, an object of the present invention is to provide a fitting that can easily lock a door/window side lock by only closing a movable door/window, or to provide a door/window side lock that occupies a small space and can lock by efficiently applying a force, and a fitting provided with the door/window side lock.

In order to achieve the purpose, the assembly part of the invention is an assembly part with a door and window edge lock, the door and window edge lock is provided with a lock seat part and a lock body, wherein the lock seat part is arranged on a door and window frame arranged on the indoor and outdoor boundaries, and the lock body is arranged on the door and window edge frame of a movable door and window arranged in the door and window frame in a freely sliding and closing manner and is locked with the lock seat part; the mount has a guide member that is provided on one of the sash frame and the jamb, that contacts the other of the sash frame and the jamb when the movable door/window is closed, and that guides the jamb to a predetermined position in a depth direction of the sash frame; the lock seat component is provided with a contacted part contacted with the lock main body when the movable door and window is closed, and a locking part for locking the lock main body; the lock body includes a hook member having a contact portion that comes into contact with the contacted portion when the movable door/window is closed, and a hook portion that comes into contact with the contacted portion at the contact portion and rotates about a rotation axis to be locked to the lock portion; before the contact portion is brought into contact with the contacted portion, the other of the sash frame and the jamb is brought into contact with the guide member provided on the one of the sash frame and the jamb.

With such an assembly, if the moving door or window is moved in the closing direction, the jamb or the sash is brought into contact with the guide member before the contact portion is brought into contact with the contacted portion, and therefore the rail of the jamb is directed toward the predetermined position by the guide member before the contact portion is brought into contact with the contacted portion. Therefore, the door sash frame provided with the lock base member and the door sash frame provided with the lock body can be overlapped in the depth direction before the contact portion and the contacted portion come into contact with each other, and therefore the contact portion and the contacted portion can be reliably brought into contact with each other and reliably locked. Therefore, it is possible to provide a fitting capable of easily locking the door and window side lock only by performing an operation of closing the moving door and window.

In such an assembly, it is preferable that the guide member is provided in the window and door frame, and the window and door frame is brought into contact with the guide member before the contact portion is brought into contact with the contacted portion.

With such an assembly, if the moving sash is moved in the closing direction, the jamb comes into contact with the guide member before the contact portion contacts the contacted portion, and therefore the jamb has already contacted the guide member when the contact portion contacts the contacted portion, so that the guide member causes the trajectory of the jamb to be directed earlier in the direction of the prescribed position. Therefore, the door sash provided with the lock base member and the door sash provided with the lock body can be overlapped in the depth direction prior to the contact of the contact portion and the contacted portion, and thus can be locked more reliably.

Preferably, in the fitting, the predetermined position is a position where the contact portion contacts the contacted portion and the hook member is locked to the lock portion when the jamb moves in a direction of closing the moving door or window after being guided.

With such an assembly, the jamb is arranged in the following positions: after being guided, if the moving door or window is further moved in the closing direction, the contacted portion is contacted with the contact portion, and the hook member is locked to the lock portion. Therefore, it is possible to provide a fitting that can reliably lock the door and window side lock only by performing an operation of closing the moving door and window.

Preferably, in the above-described attachment, the hook portion contacts the contacted portion by closing the movable door/window and rotates about the 1 st axis as the rotation axis, and includes: a 1 st urging member that urges the hook member to rotate in a direction to release the lock with the lock portion; a rotation restricting member which contacts the hook member and restricts rotation of the hook member to maintain a locked state of the locked portion with the hook member, and releases restriction of rotation of the hook member when an operating portion for performing an operation of rotation centering on a 2 nd axis is operated; and a 2 nd urging member that urges the rotation restricting member so that the rotation restricting member restricts rotation of the hook portion in a direction to release the locking of the hook member and the locked portion; the axis of the 2 nd shaft is arranged closer to the indoor side than the contacted part, and the axis of the 1 st shaft is arranged closer to the indoor side than the contacted part and closer to the door and window side than the axis of the 2 nd shaft; the hook member and the rotation restricting member are located closer to the indoor side than the axial center of the 1 st shaft and the axial center of the 2 nd shaft, and contact each other between the axial center of the 1 st shaft and the axial center of the 2 nd shaft in the apparent direction.

With such an assembly, the distance between the 2 nd shaft and the operating portion becomes shorter than in the case where the 2 nd shaft is closer to the outdoor side than the contacted portion, and the 1 st shaft or the contact portion between the hook member and the rotation restricting member is closer to the indoor side than the contacted portion, so that each member such as the hook member or the rotation restricting member can be made smaller, and the occupied space of the door/window side lock can be further reduced.

In such a fitting, the 1 st axis and the 2 nd axis are preferably arranged in parallel to each other in the longitudinal direction of the jamb.

With such an assembly, both the hook member that rotates about the 1 st axis and the rotation restricting member that rotates about the 2 nd axis can be formed to be long in the longitudinal direction of the jamb. That is, since the contact portion between the hook portion of the hook member and the lock portion of the lock housing member or the contact portion between the hook member and the rotation restricting member on which the urging force of the 1 st urging member and the urging force of the 2 nd urging member act can be increased without changing the magnitude in the apparent direction and the depth direction, a fitting having a door and window side lock which is less likely to be damaged and a fitting having a door and window side lock which can be locked firmly can be realized.

In such a fitting, preferably, in order to maintain the locked state between the hook member and the lock portion, a plurality of portions that come into contact with the rotation restricting member are provided in the hook member in accordance with a rotation angle of the hook member when the hook portion is locked to the lock portion.

In the case of 2-part locking, there is a possibility that the two parts may be shaken due to the processing accuracy, mounting accuracy, construction accuracy, etc. of the parts, however, according to the assembly including the door/window side lock, in order to maintain the locked state of the hook member and the locked portion, a plurality of portions contacting the rotation restricting member are provided in the hook member in accordance with the rotation angle of the hook member when the hook portion is locked with the locked portion, and therefore, the portions contacting the rotation restricting member of the hook member can be changed in accordance with the processing accuracy, etc. of the parts. Therefore, the locked portion between the hook portion of the hook member and the lock housing member can be locked reliably without rattling.

Preferably, in the assembly, the movable door/window includes a resin door/window frame having a hollow portion; a reinforcing member having a base plate extending in a depth direction, an outdoor side plate extending from an outdoor side end of the base plate toward the door sash side, and an indoor side plate extending from an indoor side end of the base plate toward the door sash side is provided in the hollow portion of the door sash; the axial center of the 2 nd shaft is disposed in a space defined by the base sheet, the outdoor side sheet, and the indoor side sheet of the reinforcement member.

With such an assembly, it is possible to use profiles provided in the jambThe axial center of the 2 nd shaft is disposed in the space inside the reinforcing member in the shape of a letter, and the apparent size of the jamb can be further reduced.

According to the present invention, it is possible to provide an assembly that can easily lock a door/window edge lock by only closing a movable door/window, and to provide an assembly that has a door/window edge lock that occupies a small space and that performs locking by efficiently applying a force.

In the assembly 10 of the present embodiment, the axial center of the 2 nd shaft 35 is disposed in a space defined by the bottom plate 15a, the outdoor side sheet 15b, and the indoor side sheet 15c of the reinforcing member 15.

Thus, by utilizing the profile of the door disposed within the jamb 14The apparent size of the jamb 14 can be further reduced by disposing the axial center of the 2 nd shaft 35 in the space inside the reinforcing member 15 having a letter shape.

And, for example, as shown in FIG. 4, will be sectioned intoThe space defined by the reinforcing member 15 having a shape like a letter can be used as the rotation range of the hook member 37 or the rotation restricting member 39, or the restricting member side spring 40 can be disposed in the space, whereby the apparent size of the jamb 14 can be reduced.

Next, the operation of the guide member 18 and the locking of the door edge lock 20 when the inner door/window 12 is moved will be described with reference to fig. 5. In fig. 5, similarly to fig. 4, the guide member 18 is shown as a broken line in order to show the door/window side lock 20 positioned below the guide member 18.

As shown in fig. 5(a), in a state where the lock between the lock housing member 22 and the lock body 30 is released and the vertical frame 11a and the door jamb 14 are positioned apart from each other in the apparent direction (the sliding direction of the inner door/window 12), the front end of the hook member 37 is urged by the hook member side spring 38 in the direction of turning toward the indoor side, and the hook portion 37b is brought into contact with the upper and lower turning restriction pieces 36f of the base 36, whereby the state is maintained.

The rotation restricting member 39 is urged by the restricting member side spring 40 and contacts the release-time contact portion 37h of the hook member 37. At this time, the operation piece 39b of the rotation restricting member faces the indoor side and is locked with the grip portion 32d of the operation lever 32. At this time, the inner door window 12 is guided only by the guide rail provided in the lower frame and the upper frame, and therefore, the position in the depth direction of the vertical frame 11a is not accurately positioned.

When the inner door/window 12 is closed from the state of fig. 5(a), first, as shown in fig. 5(b), the corner portions of the indoor side groove wall portion 14e and the indoor side wall portion 14g of the jamb 14 are brought into contact with the indoor side tapered portion 18c of the guide member 18. At this time, the pressing portion 37c of the hook member 37 does not contact the contacted portion 26a of the latch member 22, but the front end of the jamb 14 starts to enter the groove portion 11b of the vertical frame 11 a.

In the example of fig. 5(b), since the inner door window 12 is located further to the outdoor side than the predetermined position, the indoor side groove wall portion 14e of the door frame 14 and the corner portion of the indoor side door window wall portion 14g contact the indoor side tapered portion 18c of the guide member 18, whereas when the inner door window 12 is located further to the outdoor side than the predetermined position, the corner portion of the outdoor side groove wall portion 14f and the outdoor side door window wall portion 14h contact the outdoor side tapered portion 18c of the guide member 18. Here, the predetermined position means: the hook portion 37b is located closer to the indoor side than the locking wall portion 26 of the lock housing member 22 provided on the vertical frame 11a, and the pressing portion 37c is located in parallel with the locking wall portion 26 (contacted portion 26a) of the lock housing member 22 in the apparent direction.

Further, if the inner door window 12 is moved toward the vertical frame 11a and closed, the corner portions of the indoor side groove wall portion 14e and the indoor side door window wall portion 14g slide along the indoor side tapered portion 18c of the guide member 18, and the door frame 14 moves toward the indoor side and moves toward the vertical frame 11 a. Subsequently, after the indoor side groove wall portion 14e faces the indoor side surface of the guide projection 18b of the guide member 18, as shown in fig. 5(c), the pressing portion 37c of the hook member 37 contacts the contacted portion 26a of the key receiving member 22 located below the guide member 18. At this time, the guide projection 18b of the guide member 18 enters the groove portion 14c of the jamb 14.

When the inner door/window 12 is moved toward the vertical frame 11a and closed from the state shown in fig. 5(c), the pressing portion 37c is pressed by the contact portion 26a in the apparent direction, and the hook member 37 starts to rotate as follows: the tip of the hook 37b moves to the outdoor side against the urging force of the hook-side spring 38 around the 1 st shaft 34. At this time, the hook 37b starts moving to the outdoor side with the rotation of the hook 37, and the release-time contact portion 37h starts sliding on the door-window-side surface of the restriction portion 39c of the rotation restriction member 39. Thereafter, the contact position with the restricting portion 39c of the release contact portion 37h is moved from the 2 nd shaft 35 side to the tip side of the restricting portion 39 c.

Then, if the hook member 37 is continuously rotated, the hook portion 37b is locked with the locked portion 26 b. On the other hand, if the release-time contact portion 37h moves away from the door-window-side surface beyond the tip of the restricting portion 39c, the rotation restricting member 39 rotates in the direction in which the tip of the restricting portion 39c moves from the door-window side toward the outdoor side due to the urging force of the restricting-member-side spring 40. The rotation of the rotation restricting member 39 causes the tip of the restricting portion 39c to contact the restricting contact portion 37d of the hook member 37. In this state, since the contact portion 37d comes into contact with the tip end of the restricting portion 39c during restriction of the hook member 37, the hook member 37 becomes unable to rotate due to the urging force of the hook member side spring 38, and the locked state in which the hook portion 37b is locked with the lock hole 26b is maintained. At this time, the operating lever 32 moves in accordance with the movement of the operating piece 39b of the rotation restricting member 39, and the operating portion 32a moves toward the door side.

Then, in a state where the hook portion 37b is locked by being locked in the locking hole 26b, the operation portion 32a is moved toward the indoor side wall portion 31b of the base member 31, and the rotation restricting member 39 is rotated against the urging force of the restricting member side spring 40, so that the contact between the restricting portion 39c and the restricting-time contact portion 37d is released. In this way, the tip of the hook 37b is rotated by the urging force of the hook-side spring 38, and the engagement of the hook 37b with the engagement hole 26b can be easily released, thereby easily releasing the lock.

With the above-described fitting 10, if the moving doors 12 and 16 are moved in the direction of closing the moving doors 12 and 16, that is, in the direction in which the doorjambs 14 and 17 and the side rail 11a are close to each other, the doorjamb 14 comes into contact with the guide member 18 before the pressing portion 37c comes into contact with the contacted portion 26a, and therefore the doorjamb 14 comes into contact with the guide member 18 when the pressing portion 37c comes into contact with the contacted portion 26 a. For this reason, the rail of the jamb 14 can be oriented toward the predetermined position by the guide member 18 at an earlier time. Therefore, the door sash frame 11 provided with the lock base member 22 and the door sash frame 14 provided with the lock body 30 can be overlapped in the depth direction before the pressing portion 37c comes into contact with the contacted portion 26a, and therefore, the locking can be performed more reliably.

In the above-described embodiment, the example in which the jamb 14 is brought into contact with the guide member 18 before the pressing portion 37c is brought into contact with the contacted portion 26a has been described, but the timing in which the pressing portion 37c is brought into contact with the contacted portion 26a may be the same as the timing in which the jamb 14 is brought into contact with the guide member 18. Thus, when the moving windows 12 and 16 are moved in the closing direction, the doorjambs 14 and 17 can be brought into contact with the guide member 18 before the pressing portion 37c comes into contact with the contacted portion 26 a. In this case, the rail of the jamb 14 is directed toward the predetermined position by the guide member 18 before the pressing portion 37c comes into contact with the contacted portion 26 a. Therefore, the door sash frame 11 provided with the lock base member 22 can be overlapped with the position in the depth direction of the door sash frame 14 provided with the lock body 30 before the pressing portion 37c comes into contact with the contacted portion 26a, and the locking can be reliably performed. Thus, the fitting 10 can be provided which can easily lock the door/window edge lock 20 by only performing the operation of closing the movable doors/windows 12 and 16.

The predetermined positions to which the jamb 14 is guided by the guide member 18 are: after the jamb 14 is guided, when the moving doors 12 and 16 are moved in the closing direction, the contacted portion 26a contacts the pressing portion 37c, and the hook member 37 is locked in the position of the locking hole 26 b. Thus, when the jamb 14 is guided by the guide member 18, it is arranged as follows: when the moving doors and windows 12 and 16 are moved in the closing direction, the pressing portion 37c contacts the contacted portion 26a, and the hook member 37 is locked in the locking hole 26 b. It is therefore possible to provide the fitting 10 that can reliably lock the door and window edge lock 20 by only performing the operation of closing the moving doors and windows 12, 16.

Next, the operation of the lock housing member 22 and the lock body 30 for locking the door/window side lock 20 by the movement of the inner door/window 12 will be described with reference to fig. 6.

As shown in fig. 6(a), in a state where the lock between the lock housing member 22 and the lock body 30 is released, the hook 37 is urged by the hook-side spring 38 in a direction in which the tip rotates toward the indoor side, and the hook 37b is maintained by being in contact with the upper and lower rotation restricting pieces 36f of the base 36. At this time, as described above, the hook portion 37b is provided on the indoor side of the locking wall portion 26 of the lock receiving member 22 provided on the vertical frame 11a, and the pressing portion 37c is arranged at a position in parallel with the locking wall portion 26 (contacted portion 26a) of the lock receiving member 22 in the apparent direction.

The rotation restricting member 39 is urged by the restricting member side spring 40 to contact the release-time contact portion 37h of the hook member 37. At this time, the operation piece 39b of the rotation restricting member faces the indoor side and is locked with the grip portion 32d of the operation lever 32.

If the inner door/window 12 is closed from the state of fig. 6(a), first, as shown in fig. 6(b), the pressing portion 37c of the hook member 37 contacts the contacted portion 26a, wherein the contacted portion 26a contacts the front end of the locking wall portion 26 as the latch seat member 22. Thereafter, if the inner door/window 12 is further brought close to the vertical frame 11a, as shown in fig. 6(c), the pressing portion 37c is pressed by the contact portion 26a in the apparent direction, and the hook member 37 is rotated about the 1 st shaft 34, so that the tip of the hook portion 37b moves to the outdoor side against the urging force of the hook member side spring 38. At this time, the hook 37b starts moving to the outdoor side with the rotation of the hook 37, and the release-time contact portion 37h starts sliding on the door-window-side surface of the restriction portion 39c of the rotation restriction member 39. Subsequently, the contact position of the contact portion 37h with the regulating portion 39c at the time of release moves from the 2 nd shaft 35 side to the tip side of the regulating portion 39 c.

Then, if the hook member 37 is continuously rotated, the hook portion 37b is locked with the locked portion 26 b. On the other hand, if the release-time contact portion 37h moves away from the door-window-side surface beyond the tip of the restricting portion 39c, the rotation restricting member 39 rotates in the direction in which the tip of the restricting portion 39c moves from the door-window side toward the outdoor side due to the urging force of the restricting-member-side spring 40. The rotation of the rotation restricting member 39 causes the tip of the restricting portion 39c to contact the restricting contact portion 37d of the hook member 37. In this state, the restricting contact portion 37d of the hook member 37 contacts the tip of the restricting portion 39c, so that the urging force of the hook member-side spring 38 makes the hook member 37 unable to rotate, and the locked state in which the hook portion 37b is locked to the lock hole 26b is maintained. At this time, the operating lever 32 moves in accordance with the movement of the operating piece 39b of the rotation restricting member 39, and the operating portion 32a moves toward the door side.

Further, in a state where the hook portion 37b is locked by being locked in the locking hole 26b, the operation portion 32a is moved toward the indoor side wall portion 31b of the base member 31, and the rotation restricting member 39 is rotated against the urging force of the restricting member side spring 40, and if the contact between the restricting portion 39c and the restricting-time contact portion 37d is released, the distal end of the hook portion 37b is rotated by the urging force of the hook member side spring 38, and the locking between the hook portion 37b and the locking hole 26b can be released, and the locking can be easily released.

As shown in fig. 7, 3 different surfaces of the restricting contact portion 37d of the present embodiment are formed in a stepped shape. Immediately after the release-time contact portion 37h passes the tip of the regulating portion 39c, as shown in fig. 6(d) and 7(a), the tip of the regulating portion 39c contacts the regulating-time contact portion 37d (hereinafter, referred to as tip-side regulating-time contact portion 37e) of the hook member 37 provided at the position farthest from the 1 st shaft 34. When the inner door window 12 is in a state in which the front end of the restriction portion 39c is in contact with the front end side restriction contact portion 37e and cannot move in a state in which the front end of the restriction portion 39c is in contact with the vertical frame 11a, the state in which the front end of the restriction portion 39c is in contact with the front end side restriction contact portion 37e is maintained.

At this time, the contact portion between the hook member 37 and the rotation restricting member 39 is closer to the indoor side than the axial center of the 1 st shaft 34 and the axial center of the 2 nd shaft 35, and the axial center of the 1 st shaft 34 and the axial center of the 2 nd shaft 35 in the apparent direction are in contact with each other. In this state, the hook member side spring 38 urges the hook member 37 in the direction in which the contact portion 37e faces the outdoor side at the time of front end side regulation, and the regulating member side spring 40 urges the rotation regulating member 39 in the direction in which the regulating portion 39c faces the outdoor side. Therefore, in the apparent direction, between the hook member 37 and the rotation restricting member 39, the front ends of the contact portion 37e and the restricting portion 39c are urged in the direction of rotation from between the hook member 37 and the rotation restricting member 39 toward the outdoor side at the time of restriction of the front end side which is closer to the indoor side than the 1 st shaft 34 and the 2 nd shaft 35 are. Therefore, the hook 37 and the rotation restricting member 39 restrict the rotation of each other, and the urging forces of the hook-side spring 38 and the restricting-member-side spring 40 can be efficiently applied.

In a state where the tip end of the restricting portion 39c is in contact with the tip end side restricting contact portion 37e, when the inner window 12 is movable toward the vertical frame 11a, the inner window 12 is further moved toward the vertical frame 11a, but when the restricting contact portion 37d is 1, rattling remains between the inner window 12 and the vertical frame 11a even in the locked state. Therefore, the fitting 10 includes 2 restricting contact portions 37f and 37g in addition to the distal-end restricting contact portion 37 e. In this way, when the inner door window 12 can move toward the vertical frame 11a with the tip end of the restricting portion 39c in contact with the tip end side restricting contact portion 37e, as shown in fig. 7(b), the tip end of the restricting portion 39c is brought into contact with the restricting contact portion 37d located at the center (hereinafter, referred to as the center restricting contact portion 37f) among the 3 restricting contact portions 37e, 37f, and 37g by further moving the inner door window 12 toward the vertical frame 11a, so that the inner door window 12 can be locked without rattling between the inner door window 12 and the vertical frame 11 a. When the tip of the restriction portion 39c contacts the center-time restriction contact portion 37f and the inner door window 12 can move toward the vertical frame 11a, the tip of the restriction portion 39c contacts the restriction-time contact portion 37d closest to the 1 st shaft 34 side (hereinafter referred to as a shaft-side restriction contact portion 37g) by moving the inner door window 12 further toward the vertical frame 11a as shown in fig. 7c, whereby the inner door window 12 and the vertical frame 11a can be locked without rattling.

In this way, in order to maintain the locked state of the hook portion 37b and the locking hole 26b, the restricting contact portion 37d with which the tip end of the restricting portion 39c of the rotation restricting member 39 comes into contact is provided with 3 steps corresponding to the rotation angle of the hook member 37 when the hook portion 37b is locked with the locking hole 26b, and therefore, the restricting contact portion 37d with which the tip end of the restricting portion 39c comes into contact is changed, and locking can be performed reliably without rattling. Further, in the case where 2 or more members are locked together, there is a case where the members are shaken between them due to the processing accuracy, the mounting accuracy, the construction accuracy, and the like of the members, but since the plurality of step-like restricting contact portions 37d which are brought into contact with the tip ends of the restricting portions 39c are provided for restricting the rotation of the hook member 37, the shaking between the members can be suppressed, and the locking can be reliably performed.

According to the fitting 10 of the above embodiment, since the axial centers of the 1 st shaft 34 and the 2 nd shaft 35 are both disposed closer to the indoor side than the contacted portion of the latch base member 22, the hook member 37 that rotates about the 1 st shaft 34 and the rotation restricting member 39 that rotates about the 2 nd shaft 35 are disposed closer to the indoor side than the contacted portion in the depth direction. At this time, since the indoor side is the side where the locking of the hook 37b and the locking hole 26b is released, the space occupied by the door/window side lock 20 can be further reduced.

The section of the resin frame 14 isThe axial center of the 2 nd shaft 35 is disposed in the space inside the reinforcing member 15, and therefore the apparent size of the jamb 14 can be further reduced.

In addition, other parts of the locking body, for example, as shown in fig. 4, are formed by using a cross-section ofThe space defined by the reinforcing member 15 having a rectangular shape is used as the rotation range of the hook member 37 or the rotation restricting member 39, or the restricting member side spring 40 is disposed in the space, so that the apparent size of the jamb 14 can be reduced.

Further, the hook-member-side spring 38 urges the hook member 37 to rotate in a direction to release the locking of the hook portion 37b with the locking hole 26b, and the restricting-member-side spring 40 urges the rotation restricting member to restrict the rotation of the hook member 37 in a direction to release the locking of the hook portion 37b with the locking hole 26 b. Therefore, in a state where the rotation restricting member 39 is in contact with the hook member 37 and the rotation of the hook member 37 is restricted, the urging force of the hook member side spring 38 and the urging force of the rotation restricting member side spring 40 act in opposite directions.

Then, by closing the inner door/window 12, the hook 37b of the hook member 37 is locked in the locking hole 26b closer to the outdoor side than the axis center of the 1 st shaft 34 as the rotation center of the hook member 37, and is brought into contact with the rotation restricting member 39 for restricting the rotation of the hook member 37, at a position closer to the indoor side than the axis center of the 1 st shaft 34 and between the 2 nd shaft 35. Therefore, the portion of the hook member 37 that contacts the rotation restricting member 39 is positioned on the opposite side of the hook portion 37b with respect to the 1 st shaft 34. Then, the hook-side spring 38 for urging the hook 37 urges the hook 37 to rotate in the direction of releasing the locking with the locking hole 26b, and thus, the urging force of the 1 st urging member for moving the hook 37 in the outdoor direction is applied to the portion of the hook 37 in contact with the rotation restricting member 39.

Therefore, in a state where the rotation restricting member 39 is in contact with the hook member 37 and the rotation of the hook member 37 is restricted, the portion where the hook member 37 is in contact with the rotation restricting member 39 is disposed between the axial center of the 1 st shaft 34 and the axial center of the 2 nd shaft 35 in the apparent direction and further on the indoor side than the axial center of the 1 st shaft 34 and the axial center of the 2 nd shaft 35, so that the rotation of the rotation restricting member 39 can be restricted by the urging force of the hook member side spring 38, and the rotation of the hook member 37 can be restricted by the urging force of the restricting member side spring 40, and the urging force of the hook member side spring 38 and the restricting member side spring 40 can be efficiently applied to perform locking.

Further, since the vertical direction along which the 1 st axis 34 and the 2 nd axis 35 extend is the longitudinal direction of the jamb 14, both the hook member 37 that rotates about the 1 st axis 34 and the rotation restricting member 39 that rotates about the 2 nd axis 35 can be formed to be long in the vertical direction (the longitudinal direction of the jamb 14). That is, since the contact portion between the hook portion 37b of the hook member 37 and the locking hole 26b (locking portion) of the housing member 22 or the contact portion between the hook member 37 and the rotation restricting member 39 on which the urging force of the hook member side spring 38 and the urging force of the restricting member side spring 40 act can be formed to be large, the door and window side lock 20 which is less likely to be damaged can be realized, and the door and window side lock 20 which can be locked firmly can be realized.

Further, compared to the case where the 2 nd shaft 35 is closer to the outdoor side than the contacted portion (the locked wall portion 26), since the 2 nd shaft 35 is disposed closer to the indoor side and the distance between the 2 nd shaft 35 and the operating portion 32a can be reduced, the size of the rotation restricting member 39 that rotates about the 2 nd shaft 35 as the axis can be reduced. In this way, the depth dimension of the doorjamb 14 provided with the doorjamb lock 20 can be reduced.

The mount 10 of the above embodiment is provided with the door/window side lock 20 capable of locking by efficiently applying the urging forces of the hook member side spring 38 and the regulating member side spring 40, and can have a good protection property.

In the above embodiment, the frame constituting the movable door/window is made of resin, but the present invention is not limited to this, and the frame may be made of an aluminum extruded member, for example.

Also, the above-described embodiments are provided for easy understanding of the present invention, and are not intended to limit and explain the present invention. The present invention may be modified and improved without departing from the gist thereof, and it is needless to say that the present invention also includes equivalents thereof.

For example, in the above-described embodiment, the double-sliding window is exemplified, but the present invention is not limited to this, and a single-side sliding window in which the movable window is provided in the window frame so as to be slidably openable and closable in the horizontal direction, a single-hung up-down window in which the movable window is provided in the window frame so as to be slidably openable and closable in the vertical direction, or a double-hung up-down window may be provided.

In the above embodiment, the guide member 18 is provided on the door sash frame 11 (vertical frame 11a), but the guide member 18 may be provided on the movable doors 12 and 16 (doorjambs 14 and 17), and in this case, the guide member 18 comes into contact with the doorjamb 11 when the movable doors 12 and 16 are closed, thereby guiding the movable doors 12 and 16 to predetermined positions in the depth direction with respect to the door sash frame 11 (vertical frame 11 a).

In the above embodiment, the guide member 18 is provided at a position slightly above the door side lock 20, but the present invention is not limited to this, and the guide member 18 may be provided at a position slightly below the door side lock 20, or the guide member 18 may be provided at both the upper and lower portions of the door side lock 20. The guide member 18 may also be provided integrally with the door window edge latch 20 or the latch housing member 22.

In the above embodiment, the example in which the restricting-time contacting portions with which the tip ends of the restricting portions 39c contact are formed by 3 surfaces formed in a step shape has been described, but the number of the restricting-time contacting portions is not limited to 3.
