Description

[Detailed Description of the Invention] The present invention relates to a crimping device for crimping an indoor/outdoor shoji to a sash frame by locking a locking device such as a crescent lock.

Conventionally, in order to maintain the airtightness between the indoor and outdoor sliding shoji shoji and the left and right vertical frames of the sash, both shoji have been crimped to the left and right vertical sash frames, and this crimping operation is performed exclusively on the mating frame of the indoor sash. This is generally done using a crescent lock attached to the door and a crescent receiver attached to the stile of the outdoor shoji. That is, an inclined surface is formed on the rotating body of the crescent lock, and by engaging and press-contacting the inclined surface with the crescent receiver, both shojis are forcibly pressed against the sash frame. This kind of function is called the "drawing function" of the crescent lock.

However, the "pull function" of this crescent lock is affected by the vertical adjustment of both shoji doors and the mounting condition of the crescent holder, so it often does not always work reliably. Since the shoji is provided at the center in the height direction, there is an inconvenience that only the center part in the height direction of the shoji is crimped and the upper and lower ends cannot be reliably crimped. Therefore, the air and water tightness of the sash is not sufficient. There is a problem that it cannot be secured.

Therefore, the present invention solves the above-mentioned problems associated with the use of crescent locks, ensures reliable drawing operation of both shoji doors, secures crimping to the sash frame over the height direction, and secures the sash frame. The purpose of this device is to provide a crimping device that can ensure watertightness and airtightness, and its structure has been devised with unique ingenuity.The drawing function that relies on the crescent lock itself has been stopped, and the crimping device has been developed using a completely different method. It is designed to separate indoor and outdoor shoji screens.

That is, in the device of the present invention, a movable engaging body is provided on the elevating body that moves up and down in conjunction with a locking device provided on one of the connecting frames, and the movable engaging body is connected to the end of one of the connecting frames in the height direction. A fixed engaging body that protrudes from the mating surface and wedge-engages with the movable engaging body is attached to the mating surface at the end in the height direction of the other collapsing stile, and the wedge action of both engaging bodies allows for indoor and outdoor movement. It is characterized in that the shoji is crimped onto the left and right sash vertical frames.

Hereinafter, the present invention will be explained based on illustrated embodiments.

The movable engagement body C attached to the joining frame 1 of the indoor shoji A projects into the indoor side joining face A which faces the mounting part 2 located in the hollow part of the joining stile 1 and the joining stile 3 of the outdoor shoji B. As shown in FIG. 2, this protrusion 4 has an engagement surface 6 with a fixed engagement body 5, which will be described later, on the opening direction side of the indoor shoji A. As shown in FIG. 1, the engaging surface 6 has a wedge shape with a lower half as an inclined part (B) and an upper half as a vertical part (C). Moreover, this movable engagement body C has a concave groove portion 7 that opens on the side opposite to the engagement surface 6 (that is, the closing direction side of the indoor shoji A), and this concave groove portion 7 is formed in the chamber of the movable engagement body C. It extends from the outer surface 2 to the attachment part 2.

The mounting part 2 of the movable engagement body C is connected to the elevating body 8 in the hollow part 1 of the joining frame 1, and the elevating body 8 has a rod 9 that moves up and down in conjunction with the rotational operation of a locking device such as a crescent lock. are doing. That is, the movable engaging body C can be moved up and down via the elevating body 8, and in order to enable the movable engaging body C to move up and down, a vertical hole 10 is formed in the end facing surface A of the connecting frame 1. is formed, and the protruding portion 4 of the movable engaging body C protrudes from this vertically elongated hole 10 to the outside of the room.

Note that the means for converting the rotational movement of the locking device into vertical movement is not particularly special, and a conventionally known means such as a rack and pinion system is used.

The fixed engagement body 5 that engages with the engagement surface 6 of the movable engagement body C is attached to the indoor side mating surface E near the end of the outdoor shoji mating stile 3. The illustrated fixed engagement body 5 is a roller and is rotatably mounted.
Further, the fixed engagement body 5 is formed to be tapered toward the outdoor side, and correspondingly, the engagement surface 6 of the movable engagement body C is formed to be tapered toward the indoor side. The indoor and outdoor shoji A and B are brought closer together to some extent when they are engaged.

The movable engagement body C and the fixed engagement body 5 are attached so as to have a vertical positional relationship as shown in FIG. 4 in the unlocked state shown in FIG.

As shown in FIG. 2, when both shoji A and B are closed, when the locking device is operated to pull down the elevating body 8 and the movable engaging body C is lowered, the sixth shoji As shown in the figure, the engaging surface inclined part B engages with the fixed engaging body 5 and gradually presses both shoji A and B against the left and right sash vertical frames 24 and 25, and when the movable engaging body C further descends, As shown in FIGS. 1 and 7, the fixed engagement body 5 and the engagement surface vertical portion C engage with each other. Therefore, in conjunction with the drawing function of the conventional locking device attachment part, both shoji A and B are tightly crimped to the left and right sash vertical frames 24 and 25 over their entire height.

At this time, slanted pieces 26 and 27 extending toward the outside of the room are provided on the opposing surfaces of the vertical sash frames 24 and 25, respectively.
8 and 29 are provided with engagement rollers 30 and 31 that correspond to the respective inclined pieces 26 and 27, so that each door frame 28 and 29 is pulled toward the indoor side at the same time as the crimping by the drawing action, and each sash vertical frame 24,
Frame packing 32, 33 attached to 25
Crimp.

In the illustrated embodiment, in conjunction with the drawing crimping device, a device is devised to draw the joining frame 3 of the outdoor shoji B toward the indoor side when the crimping device is operated.

That is, a pulling tool D that engages the sash upper frame 12 in conjunction with the vertical movement of the movable engaging body C having the groove portion 7 is mounted inside the matching stile 3 of the outdoor shoji B.

This pulling tool D is attached to a mounting base 1 fixed to the connecting frame 3 as shown in FIGS. 4 and 5.
3, a pressing body 14 pivotally attached to the base 13 and rotating in the indoor/outdoor direction, and a rotating body 15 pivotally attached to the lower end of the pressing body 14 and rotating in the same indoor/outdoor direction. The pressing body 14 has a pressing piece 18 above the pivoting part 16 with the base 18 facing the indoor side surface of a protruding piece 17 serving as a guide rail vertically installed on the sash upper frame 12, The rotating body 15 has an arm portion 15 that protrudes toward the indoor side from a vertically elongated hole 19 formed in the joining surface E of the joining stile 3.
a, and a leg portion 15b that abuts against the outdoor side piece 20 of the base 13, and is generally formed in a substantially U-shape as a whole.

In this rotating body 15, a roller 34 is attached to the lower end of the leg portion 15b, so that when the leg portion 15b rises while contacting the outdoor side piece 20, it can rise smoothly.

Further, the arm portion 15a is connected to the concave groove portion 7 of the movable engaging body C.
In the illustrated embodiment, it is pushed down by the movable engaging body C that descends in conjunction with the locking operation of the locking device. The rotating body 15
rotates around the shaft mounting portion 21, and this rotation causes the leg portion 15b to rotate against the outdoor side piece 2 of the base 13.
0, the lower end of the pressing body 14 in a pivoting relationship with the rotating body 15 rotates toward the indoor side around the pivoting part 16 with the base 13. Along with this, the upper end pressing piece 18 presses the inner surface of the protruding piece 17 of the sash upper frame 12. Therefore, the outdoor shoji B is drawn toward the indoor side, and the packing 22 attached to the stile mating surface H of the shoji B is attached to the stile mating surface A and the sash upper frame 12 of the indoor shoji A. When this packing 23 is crimped to the frame packing 23,
Since the outdoor shoji joining stile 3 pushes the indoor shoji joining stile 1 toward the indoor side, the upper end of the indoor shoji joining stile 1 is also crimped to the frame packing 23.

At this time, since the fixed engagement body 5 is engaged with the vertical engagement surface C of the lowered movable engagement body C as shown in FIG.
5, the shoji A, B and the sash frame S are securely in close contact with each other over the entire periphery and at the joining part, and exhibit good watertight and airtight performance.

In addition, although the above-mentioned embodiment shows the case where the present device is attached to the upper part of the shoji stile, by attaching it to the lower part of the stile in the same way,
The pulling and pressing action of the indoor and outdoor shoji can be performed more reliably, and a pulling tool can be attached to the joining stile of the outdoor shoji to ensure the pulling action at the lower part. or,
The vertical movement of the movable engaging body and the position of the fixed engaging body are not limited to those in the embodiment, and may be in the opposite positional relationship.

As described above, the crimping device according to the present invention performs the pulling and crimping action of indoor and outdoor shoji through the wedge engagement relationship between the movable engagement body and the fixed engagement body provided on the elevating body that moves up and down in conjunction with the locking device. Since this is done near the end of the sash, there is no crimping failure with the sash vertical frame that occurs with conventional locking devices such as crescent locks, and the sash vertical frame is applied over the entire height of the shoji. It has the effect of being able to be crimped onto the frame. In addition, unlike a crescent lock, the lock is not pulled by rotating, but the lock is pulled and crimped by vertical and linear movement of the movable engaging body, so the movement distance is large and the mounting position is limited like the crescent lock. Since there is no vertical adjustment, the engagement surface between the movable engagement body and the fixed engagement body can be lengthened, and the vertical movement distance of the movable engagement body can be increased, which is sufficient to cope with misalignment of both engagement bodies due to vertical adjustment etc. It has certain advantages.
