JP 2004-285610 A

In the conventional example shown in Patent Document 1, even if the handle is detached from the window operation unit, the window operation unit remains in a state of protruding indoors from the lower frame.
For this reason, even when there is no handle, the window operating portion remains on the lower frame as a pedestal, so that the appearance of the window becomes poor. In this regard, it is conceivable to make the window operation part small and inconspicuous, but a large space is required in the window operation part in order to connect the handle to the rotating shaft, so the window operation part itself must be made small. There is a limit.

  An object of the present invention is to provide a fitting having a good appearance without exposing a pedestal connected to an operation member to the outside.

  The joinery of the present invention includes a frame body provided in a building opening, a face material supported by the frame body so as to be opened and closed, and a lock device that locks and unlocks the face material with respect to the frame body. The locking device is provided on one of the frame and the face material, and is movable between a locked position and an unlocked position, and the frame and the face material. A lock receiving portion that is provided on the other side of the lock engaging portion and engageable with the lock engaging portion, and an interlocking portion that moves the lock engaging portion in an interlocking manner by operating an operation member to move between a locked position and an unlocked position. The interlocking portion is disposed in an installation space between the prospective surface of the frame and the prospective surface of the face material, and the prospective direction of the interlocking portion is in a state where the face material is locked. The edge on the side where the operation member is inserted is the same as the edge in the prospective direction of the face material or within the installation space. The operation member is detachable from the interlocking portion, and is inserted into a space between the prospective surface of the frame body and the prospective surface of the face material from the indoor side or the outdoor side to insert the interlocking portion. It can be operated.

In the invention of this configuration, in order to unlock the face material, the operation member is inserted into the space between the prospective surface of the frame body and the prospective surface of the face material from the indoor side or the outdoor side and engaged with the interlocking portion. Thereafter, the interlocking unit is operated by the operation member. Then, the engaging portion is detached from the lock receiving portion, and the face material can be opened. On the contrary, in order to lock the face material, after closing the frame body with the face material, the interlocking portion is operated in reverse to the previous operation by the operation member. Then, the lock engaging portion moves from the unlocked position to the locked position via the interlocking portion, and the lock engaging portion is engaged with the lock receiving portion. When locked, remove the operating member from the interlocking part. Since the operation member is removed from the interlocking portion, the lock device cannot be operated.
In the present invention, the interlocking portion is disposed in the installation space provided between the face material and the frame, and in the state where the face material is locked, the operation member is in the expected direction of the interlocking portion. Since the edge on the side to be inserted is the same as the edge of the face material in the expected direction or inside the installation space, the interlocking portion to which the operating member is engaged is exposed from the edge of the face material in the expected direction. The appearance of the joinery is good.

  In the joinery of the present invention, the interlocking unit includes a lever that is rotated by the operation member, an operating piece that is connected to the lever and moves forward and backward by the rotating operation of the lever, and the operating piece and the lock engaging unit.

A configuration is preferred.

In this configuration, when the operating member is mounted on the lever and the rotation operation is performed with the face material locked, the engagement pin provided on the lever moves in the idle region of the engagement groove. In a state where the engagement pin is moving in the idling region, the lever is allowed to rotate, but the operating piece remains unmoved and a part of the lever is pulled out from the edge of the face material in the expected direction. When a part of the lever is pulled out from the face material, the engaging position of the operating member with the lever is changed as necessary. Thereafter, when the lever is further rotated by the operation member, the engagement pin is engaged with the engagement region from the idle rotation region, and the operation pin moves forward by moving the engagement pin through the engagement region by the rotation of the lever. To do. Then, the lock engaging portion moves from the locked position to the unlocked position via the link portion, and the lock engaging portion is detached from the lock receiving portion, and the face material can be opened.
According to the above configuration, the engagement groove that engages with the engagement pin allows the rotation operation of the lever to move in addition to the engagement region that transmits the rotation operation of the lever to the operation piece. Therefore, when the lever is pulled out from the face material, the operating piece does not move and a large force is not applied. Therefore, the operation member can be attached to the lever at a position where the force is most easily applied in a state where a part of the lever is exposed from the face material, and unlocking operation can be easily performed.

In the joinery of the present invention, it is preferable that the locking device includes a biasing member that maintains a state where the lever does not protrude from an end edge in the prospective direction of the face material.
In this configuration, even when the engagement pin provided on the lever is in the idle region of the engagement groove and the lever is easily rotated, the lever is maintained in a state in which the lever does not protrude from the face material. Is done. For this reason, even if an external force is applied to the face material or locking device due to an earthquake or the like, the lever will accidentally protrude from the edge of the face material in the expected direction when the face material is locked. Since there is no, it can maintain a good appearance.

In the fitting according to the present invention, it is preferable that an engagement protrusion is provided at a tip of the operation member, and an engagement notch that is engageable with the engagement protrusion is provided in the lever.
In this configuration, the engaging protrusion of the operating member is inserted into the inside of the opening of the engaging notch of the lever to engage the operating member with the engaging notch, and in this state, the operating member is pulled to facilitate the lever. It can be pulled out.

In the joinery of the present invention, it is preferable that the lever is further provided with an engagement hole that can be engaged with the engagement protrusion.
In this configuration, the engaging protrusion of the operating member is engaged with the engaging notch of the lever, the operating member is pulled and the lever is pulled out from the face material, and then the engaging protrusion is engaged with the engaging hole and is operated by the operating member. Operate the lever. Since the engaging protrusion of the operating member is engaged with the engaging hole, the operating member is difficult to be removed from the lever, and the force of the operating member can be efficiently transmitted to the lever.

In the joinery according to the present invention, the operation member includes a distal end portion provided with the engagement protrusion and a proximal end portion formed with a grip portion, and the engagement protrusion is disposed at a most distal end side. A configuration including one engagement protrusion, and a second engagement protrusion and a third engagement protrusion that are spaced apart from each other by the same dimension as the first engagement protrusion is preferable.
In this configuration, the lever is pulled out by engaging the engagement notch with the first engagement protrusion, and then one of the second engagement protrusion and the third engagement protrusion is engaged with the engagement hole, and the lever is operated with the operation member. Is rotated in a predetermined direction, for example, clockwise. Further, when the mounting position of the hinge device or the like of the face material is reversed, the second engaging protrusion and the third engaging protrusion are engaged after engaging the engaging notch with the first engaging protrusion and pulling out the lever. The other is engaged with the engagement hole, and the lever is rotated in a predetermined direction, for example, counterclockwise by the operation member.
As a result, even with a face material having different mounting positions at the rotation center of the face material, such as a hinge device, the face material can be selected with only one operation member by selecting the engagement protrusion to be used among the three engagement protrusions to be used. Can be locked and unlocked. Therefore, even if there are a plurality of types of face materials, the operation member can be shared, so that the cost can be reduced.

However, if the engagement notch 81 is used to pull out the lever 8 as in the above-described embodiment, the operation member 6 is moved to the lever 8 even if the lever 8 is locked and hidden between the shoji 2 and the eyeless body 12. By inserting toward the first, the engagement protrusion 61 can be easily engaged with the first engagement notch 81. Furthermore, all the objects engaged with the first engagement protrusion 61, the second engagement protrusion 62, and the third engagement protrusion 63 may be formed from engagement notches.
Further, in the present invention, a protrusion may be provided on the lever 8 and a hook engaged with the protrusion may be provided on the plate 60 of the operation member 6. Furthermore, the operation member 6 is not limited to a plate shape, and may be formed from a rod-shaped member. In particular, operability is improved by forming the grip portion from a rod-shaped member.

  In the above-described embodiment, the engaging groove 93 is provided with an engaging region 93A for transmitting the rotating operation of the lever 8 to the operating piece, and is provided continuously with the engaging region 93A to allow the rotating operation of the lever 8 to operate. In the present invention, only the engagement region may be used and the idle region may be omitted. In this configuration, a load is applied to the operation member from the time when the lever starts to rotate. However, when the entire locking device is lightweight and operates smoothly, there are few inconveniences in use.

In the above embodiment, the joinery has been described as an inner window, but it may be an outer window. In the case of an open window, it may be a window that is opened only when a fire brigade or the like tries to enter the indoor side from the outdoor side in an emergency such as a fire.
Moreover, the joinery of the present invention can be used for an inward-facing window or an outward-facing window, and can also be used for a vertical window.

Furthermore, the frame body is not limited to the frame body composed of the vertical 11 and the seamless body 12 and the shoji 2 that is the face material is supported, and the frame body may be a window frame that is a four-frame frame structure. For example, it may be composed of a single panel material or the like.
Moreover, in the said embodiment, although the lock engaging part 51 and the interlocking | linkage part 7 were provided in the shoji 2, and the lock receiving part 52 was provided in the vertical 11 among the lock apparatuses 5, in this invention, it is contrary to this. In other words, the lock engaging portion 51 and the interlocking portion 7 may be provided on the vertical 11 and the seamless 12, and the lock receiving portion 52 may be provided on the shoji 2.

  Moreover, in the said embodiment, a structure like a general cylinder lock may be sufficient as a locking device, and other arbitrary types of lock | rocks can be utilized. In the present invention, the operation member may be an operation member having only a function for unlocking the locking device, for example, an operation knob, a lever, a dial, or the like. A fixed handle for opening the material may be separately provided.
