[Conventional technology]

Generally, as a sliding sash window of this kind fixed inside and movable outside, as is well known,
The inside of both left and right sleeves was used as a window, and the outside of the middle part was used as an opening and closing window, so-called both sleeves, and one of the left and right sleeves was used as a window and the other sleeve was used. There is a so-called one-sleeve inset window with the outside of the window as an opening / closing window.

However, in the case of the former both-sleeve fitting window, the configuration of these sash windows is, as shown in FIGS. 4 (a) and 4 (b), the upper and lower horizontal frames (2). ), (3) and the left and right vertical frames (4), (5) are provided in the window frame body (1), and the window frame body (1) is provided in each part of the left-right direction approximately 1/3. Left and right inner summing frames (6) and (7) are erected at the corresponding inner positions, and both left and right sleeve parts with these inner summing frames (6) and (7) as boundaries. Window glasses (8) and (9) are fixed to the inner window sleeves (A ₁ ) and (A ₂ ) of the inner sleeves, and further, the inner summing frames (6) and (7). The upper and lower horizontal frames (11), (12) and the left, corresponding to the outer position between
The shoji frame (1) consisting of the right outer siding frames (13), (14)
0) is provided, and a window glass (15) is fitted to the shoji frame body (10) to form an outer shoji (B) at an outer middle portion, and the shoji screen (B) is attached to the window frame body (1). ) Is attached so that it can be slidably opened and closed in either the left or right direction indicated by the arrow.
Regarding the locking of the outer shoji (B) in the outer middle part with respect to the respective fitting windows (A ₁ ) and (A ₂ ) of the inner sleeve parts, these should be performed in the state shown in the figure with the outer shoji (B) closed. Place the crescent locks (C) on the left and right on the left and right sides, respectively, between the inner stiles (6), (7) and the outer sashes (13), (14) of both parties. I am trying to do it.

Also, in the case of the latter one-sleeve incision window, the configuration is almost the same as in the former case, but in the latter case, the fifth
As shown in FIGS. (A) and (b), a right inner assembling frame (7) is erected at an inner position corresponding to a part of the window frame (1) in the left-right direction. A window glass (9) is fixed to the sleeve on the right side with the inner stile (7) on the right as a boundary, and it is used as a dead window (A ₂ ) for one of the inner sleeves. Further, the upper and lower horizontal frames (11) and (12) and the left vertical frame (13a) are associated with the left vertical frame (4) and the right internal assembly frame (7). ), A shoji frame body (10) consisting of the outer siding frame (14) on the right side is provided, and the window glass (1

With respect to the locking of the outer shoji (B) of the outer sleeve on the fitting window (A ₂ ) of the inner sleeve, the outer shoji (B) is closed in the illustrated state. The left vertical frame (4), the right inner calling frame (7) and the left vertical connecting frame (13a), and the right outer calling frame (14) between the left and right sides, respectively. The respective crescent locks (C) are attached to the left and right hands.

Further, regarding the mounting manner of the left and right crescent locks (C), since these are simply mounted on the left and right, the crescent locks on the right side thereof are the same. Only (C) will be described.

That is, as shown in FIGS. 6 to 8, the crescent lock (C) is configured by combining a separate actuating portion (21) and locking portion (31), and is well known in the prior art. As described above, in the actuating part (21), the mounting and fixing support pedestal (22) and the support pedestal (22) are coaxially supported by the support pedestal (22) so that they can be differentiated from each other. An operating handle (23) and a locking arm (24) having a locking roller (25) at its tip are provided, and the locking part (31) also has a mounting base (32) for mounting and fixing. And a so-called roller catch (33) which projects from the support pedestal (32) and locks the locking roller (25).

And, with respect to the side surface portion inside the window glass (15) in the outer shoring frame (14) of the shoji screen (B), a support pedestal in the operating portion (21) of the crescent lock (C). Position and install (22) as expected, inactive, that is,
In the open operation state, the operation handle (23) and the locking arm (24) are erected upright in parallel with the outer dressing frame (14), and the right fitting window (A). ₂ ) On the corresponding side surface portion of the left inner dressing frame (7), at a position separated from the operating portion (21) by a predetermined distance,
The support pedestal (32) at the locking portion (31) is attached.

Therefore, now with the shoji (B) closed, hold the actuating handle (23) of the crescent lock (C), and from the position shown by the solid line in FIG. When the push-down operation is performed, the locking arm (24) is interlocked with a preset time delay, the locking roller (25) is locked to the roller catch (33) in the process of the pressing-down operation, and the fitting window is inserted. The inner meeting frame (7) on the (A ₂ ) side and the outer meeting frame (14) on the outer shoji (B) side are attracted to each other, and a seal is arranged on one of the inner meeting frames (7) side. Piece (16)
Is pressed against the other outer fitting frame (14) and both of them can be locked in a sealed state, and this state corresponds to the closed operating position of the operating handle (23). Also,
In the locked state, the actuating handle (23) is moved from the position indicated by the chain double-dashed line in FIG. 8 to the position indicated by the solid line, and is pushed upward to the outside, whereby the operation opposite to the above is performed, and the inner combination of these The lock between the frame (7) and the outer assembly frame (14) can be released, and subsequently, the external shoji (B) can be arbitrarily opened and closed with respect to the fitting window (A ₂ ). Similarly, the state at this time corresponds to the open operating position of the operating handle (23).

[Problems to be solved by the device]

However, in the conventional locking device for the sliding sliding window configured as described above, after the crescent lock (C) is unlocked, the engagement window (A ₁ ) (Or (A ₂ )) when opening the external shoji (B), the following problems may occur.

That is, the operating handle (23) is pushed up from the closed operating position to release the lock between the inner dressing frame (7) (or (6)) and the outer dressing frame (14) (or (13)). In such a state, the inner fitting frame (7) and the outer fitting frame (14), which are pressed and tightly adhered to each other when locked and are in a secret-sealed state, have other requirements such as the closeness of adhesion between them. When the external handle (B) itself has a large weight, or the atmospheric pressure outside the room is larger than that inside the room, they are not necessarily separated from each other. ), The force is exerted in the opening direction so as to overcome these adhesion forces, and when actuating the shoji screen (B), the reaction caused by this actuation is , The insertion window (A ₁ ) where the arm holding the operating handle (23) is fixed. (Or (A ₂ )) The inner meeting frame (7) (or (6)) is strongly hit, or the inner surface of the window glass (15) and the inner meeting frame (7) (or (6))
There was a risk of being injured by being caught in the gap between.

This invention intends to solve the above-mentioned conventional problems, and its purpose is to adopt a form of a deadening window by fixing the inside, and a shoji screen by moving the outside, and In a sliding sash window that is constructed by using a crescent lock to lock the movable sliding door to the kill window, the safety of operation is effective when opening the sliding door after unlocking the lock. An object of the present invention is to provide a locking device for a sash window of this kind, which can be reliably and reliably guaranteed.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a locking device for a sliding sash window according to the present invention is provided in an open operating position with respect to an operating handle of an operating portion of a crescent lock mounted on an outer assembling frame of an outer shoji. The guard part is extended and protruded so that the operating handle cannot be completely gripped, leaving a slight gap between the summing frame and the summing frame.

That is, according to the present invention, a fitting window for fixing inside and an exterior shoji for moving outside are provided, and both of them can be locked by a crescent lock in a state where the shoji is closed with respect to the fitting window. In the pulling sash window, the operating handle that stands upright in the open operating position, the locking roller that interlocks with the operating handle, and the support pedestal that pivotally supports the operating handle and the locking roller are provided. The crescent lock is mounted on the outer shoring frame of the shoji screen, and the operating handle is extended and protrudes from the opposing guard portion with a slight gap left between the operating handle and the outer shoring frame. Part, a roller catch for releasably locking the locking roller at the closing operation position of the operation handle, and a support base for holding the roller catch. A locking device for pulling difference Satsushi window, characterized by being configured with a locking portion of the crescent tablet was mounted on the inner 召合 allowed stile of killed windows.

[Action]

Therefore, in the present invention, with respect to the operating handle in the operating portion of the crescent lock mounted on the outer retaining frame of the shoji screen, a slight gap is left between the operating handle and the outer retaining frame in the open operating position, Since the guard part that prevents the operating handle from being completely grasped is extended and protruded, it is necessary to change the operating handle once when operating the operating handle. , It is possible to prevent the danger that occurs when the shoji screen is opened vigorously while holding the operating handle.

〔Example〕

Hereinafter, an embodiment of a locking device for a sliding sash window according to the present invention will be described in detail with reference to FIGS.

1 to 3 are a front view, a plan view and a side view showing a schematic structure of a locking device according to this embodiment. In the structure of the embodiment shown in FIGS. FIG. 8 The same reference numerals as those in the conventional configuration indicate the same or corresponding parts.

That is, in the configuration of this embodiment, as in the case of the configuration of the conventional example described above, the insertion window (A ₂ ) (or (A ₁ )) fixed by the inner side and the external shoji (B) movable by the outer side are provided, and In this embodiment, as a crescent lock that engages and disengages between the two, the operating handle (23) stands upright in the open operating position, and the engaging roller (25) interlocking with the operating handle (23). The locking arm (24) and the operating handle (23) and the locking arm (24) respectively, and the operating arm (24) is in the open operating position. Support pedestal (22) that extends and projects the guard part (41) so as to leave a slight gap (a) between them.
And an operating part (21), and the operating handle (2
In the closing operation position of 3), a locking portion including a roller catch (33) for locking and locking the locking roller (25) and a support pedestal (32) for holding the roller catch (33). Provide (31).

Then, the support base (22) of the operating portion (21) of the crescent lock (C) is attached and fixed to a predetermined position of the outer assembly frame (14) (or (13)) of the outer shoji (B). By this, in the open operating position, the outer frame (14) (or (1
3)) upright on the operating handle (23),
The guard portions (41) extending and protruding from the support pedestal (22) are opposed to each other with a slight gap (a) between them, and
The support base of the engaging portion (31) of the crescent lock (C) is provided at a position corresponding to the inner assembling frame (7) (or (6)) of the fitting window (A ₂ ) (or (A ₁ )). By attaching and fixing (32), the locking roller (25) interlocking with the operating handle (23) can be detachably locked to the roller catch (33) in the closed operating position. is there.

Here, regarding the projecting length range of the guard part (41) extended from the support pedestal (22), the operating handle (23)
It is preferable to set a range that can completely prevent the grip of the operating handle (23), that is, a range that corresponds to the entire length of the operating handle (23). Also, regarding the formation position and shape of the guard part (41), Actuated handles, as in (23)
The present invention is not limited to the same axis as the above, and any position and shape can be set as long as they can completely prevent the grip of the operating handle (23).

Therefore, in the embodiment configured as described above, the guard portion is extended and projected from the support pedestal (22) at the open operation position of the operation handle (23) for operating the crescent lock (C). Since the (41) are arranged so as to face each other with a slight gap (a), the operating handle (23) cannot be directly and completely gripped. It is necessary to change the operation handle (23) once and operate the lock handle from the open operation position to the close operation position and the lock release from the close operation position to the open operation position. In other words, in other words, a relatively small operating force is required for each of the pulling-out operation of the operating handle (23) from the open operating position and the pushing operation of the operating handle (23) to the open operating position. In order to engage and disengage the locking roller (25) with respect to the roller catch (33) by the operating handle (23) in the operating position, a relatively large operating force is required. It is necessary to change hands.

In particular, at the end of the lock releasing operation, that is, at the end of the operation of moving the operating handle (23) from the closed operating position to the open operating position, the guard portion (41) interferes with the operation and at least the operating handle. There is a risk that it will not be possible to operate it while holding (23), so this operation handle should be used when performing operations such as opening the shoji (B) after unlocking the lock. The changeover operation of (23) is one of the cues for interrupting continuous operation, and it reminds the operator to pay attention to the operation.
While holding the hand grip, the arm tip holding the operating handle (23), which occurs when the external shoji (B) is vigorously opened, has a fixed insertion window (A ₂ ) (Or (A ₁ )) inner shot frame (7) (or (6)), or the window glass (15) surface and inner gathering frame (7)
It is possible to prevent the risk of being injured by being caught in the gap with (or (6)).

[Effect of device]
