DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a sash window with a built-in blind, which locks an outer sliding door and an inner sliding door which is different from the sliding door in a window in which an outer sliding door having a built-in blind is built outside. It is.

[0002]

2. Description of the Related Art An outer sash which is fitted to the outside of a room and an inner sash is stored in the room.
An external sliding door with a built-in blind is installed on the outside of the window frame with a blind installed between the external sliding door and the internal sliding door, and the sliding door is installed inside the sliding door inside the window frame. Since it is necessary to remove the inner sliding door of the sliding door, the inner sliding door is detachably stored in the frame of the outer sliding door.

However, when the inner sliding door and the outer sliding door are locked by a crescent lock, the crescent lock and the crescent receiver project from the range of the found width of the summing frame on the prospective surface on the inner shoji side of both summing frames. Since these interfere with the removal of the internal shoji, it is necessary to remove the crescent lock and the crescent receiver in order to remove the internal shoji, which is troublesome for maintenance.

[0004] The problem that the inner shoji collides with the crescent lock when the inner shoji is removed can be avoided by reducing the width of the inner door sliding door and the width of the inner shroud, but the design of the window deteriorates. Or the strength of the frame itself is reduced.

This invention was made by paying attention to the problems faced when locking a sash with a built-in blind.
The present invention intends to newly propose a locking device that does not hinder the attachment / detachment of the internal shoji and has a high design.

[0006]

According to the present invention, a concave portion is formed on the outer peripheral side of the sliding door of the inner sliding door from the inner peripheral side of the sliding door of the outer sliding door. The crescent is stored in the recess so as to be able to enter and exit from the outside of the room, and at the same time, the crescent receiver is fixed to the indoor side of the summing frame of the outer sliding door, and the crescent is placed on the facing surfaces of both the outer sliding door and the inner sliding door. By removing the locking device from the projected surface by removing the locking device, it is not necessary to remove the conventional crescent lock, etc., and to reduce the width of the stitching frame. Lock the sliding door and the internal sliding door.

The outer sliding door includes a dead-enclosed shoji that is housed outside, and an inner shoji that is detachably housed inside the room.
It consists of blinds installed between outer and inner shojis,
It is built outside the window frame. The inner sliding door is installed on the indoor side of the outer sliding door in a state of being pulled with respect to the outer sliding door. The inner sliding door of the outer sliding door is housed in the outer sliding door frame in a state where the outer sliding door and the inner sliding door are closed and can be detached to the indoor side without colliding with the combination frame of the inner sliding door.

The crescent is rotatably supported on the prospective surface of the recess, is stored in the recess so that it can be moved in and out of the surface of the sliding door, and projects from the outside of the sliding door to the found surface of the fitting frame of the sliding door. Engage with the fixed crescent receptacle.

The crescent is moved in and out by a lever arranged in the recess together with the crescent, and the lever is operated in the recess so that the sliding door does not interfere with the attachment / detachment of the inner sliding door and the inner appearance of the inner sliding door. Lock and unlock the crescent without affecting the.

The crescent and lever constituting the locking device are located within the width of the recess so as not to collide with the inner shoji when the inner shoji is removed, and the crescent receiver is within the found width of the summing frame of the outer sliding door. To position. With this arrangement, when both the outer sliding door and the inner sliding door are closed, there is no obstacle on the indoor side of the inner sliding door of the outer sliding door, and the inner sliding door is prevented from colliding with the locking device when removing the inner sliding door,
When the sliding door and the sliding door are closed, the locking device locks both sliding doors while keeping the inner sliding door removable from the sliding door to the indoor side.

[0011] The locking device is set within the range of the width of the door frame and the sliding door, and the crescent enters and exits between the opposing surfaces of the door frames in the recess of the sliding door. When the sliding door is closed, it is possible to position the prospective surface on the outer peripheral side of the summing frame of the inner sliding door on the extension line of the prospective surface on the inner peripheral side of the summing frame of the outer sliding door, or in the vicinity thereof. It is possible to secure the maximum width dimension.

[0012] Further, the locking device is placed in a recess located closer to the inner sliding door than the prospective surface of the assembling frame of the outer sliding door, so that the locking device has an external appearance of the window at any time of opening, closing, and locking. There is no influence, and there is no deterioration in the design of the window due to exposure to the outside like a crescent tablet.

The unlocking is performed by lowering the lever 2.

By the way, as described above, since the locking device D is housed closer to the inner circumference of the inner sliding door H ₂ than the prospective surface f ₁₁ of the summing frame f ₁ of the outer sliding door H ₁ by the recess f ₂₀ , the outer sliding door H ₁ and the inner sliding door H ₁ during closure of H _2, stiles allowed召合as shown in FIGS. 1 to 5
the inner peripheral side of an extension of estimated plane f ₁₁ of the stile f ₁ so召合the estimated plane f ₂₃ other than the recess of f _2, or is it possible to position near the width dimension of the inner sash s ₂ is Summing frame f ₁
Is secured to the estimated plane f _11, its opening area is effectively exploited.

[0029]

According to the present invention, a crescent which is housed in a recess formed on the outer peripheral side of a mating frame of an inner sliding door so as to be able to freely enter and exit the outer sliding door, a lever for operating the rotation of the crescent in the recess, and an outer sliding door The locking device is composed of the crescent receiver fixed to the indoor side of the summing frame, the crescent and the lever are located within the width of the recess, and the crescent receiver is within the found width of the summing frame of the sliding door. Because it is located
When both the outer sliding door and the inner sliding door are closed, there is no obstacle on the indoor side of the inner sliding door of the outer sliding door, and it is possible to prevent the inner sliding door from colliding with the locking device when removing the inner sliding door. That is, when the outer sliding door and the inner sliding door are closed, both sliding doors can be locked by the locking device while the inner sliding door can be detached from the outer sliding door to the indoor side.

Further, since the locking device is installed between the summing frame of the outer sliding door and the inner sliding door, it is not exposed from the summing frame both at the time of opening and at the time of closing. There is no influence and the design is improved.

In addition, since the locking device is set within the range of the width of the door frame, the prospective surfaces of the door sliding door and the door sliding door can be matched to ensure the maximum width of the inner sliding door. , Sufficient strength of the frame itself can be secured.
