Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a shoji fanning device that is attached between a window frame and a shoji that is pivotally supported so as to be swingable in opening and closing.

[Technical background of the invention and its problems]

As is well known, in the case of casement windows in which the shoji is pivotally supported on the window frame so that it can swing open and close, a fan is placed between the window frame and the shoji to prevent the shoji opened to the outside of the window from swinging due to the wind. It is used to attach a stop. It is desirable that this fan stopper is easy to install and also allows the shoji to be easily swung open and closed. Kaisho
No. 59-71872, etc., have been devised in various ways. Also, since the fan stopper is installed between the window frame and the shoji,
If the fan stopper is large, the watertight structure will be complicated, and a part of the fan stopper will be visible from the outside, making the window look unsightly.

[Purpose of invention]

Therefore, the purpose of this invention is to make the locking device as thin as possible so that the locking device can be installed more easily and is not exposed to the outside in the installed state.

The proposed anti-adjustment device is a link-type anti-adjustment device in which the tips of the main link and the sub-link are overlapped vertically and connected face-to-face, with a shaft support hole and an insertion hole provided at the tip of the main link, and A square hole that connects to the shaft support hole of the main link is provided at the tip, and an insertion hole that communicates with the insertion hole when the link legs are opened, and the cover is inserted into the square hole of the sub link on the front cover that overlaps the connecting part of the sub link. A shaft part that is locked and inserted into the shaft support hole of the main link is provided, and a small diameter through hole that communicates with the insertion hole of the sub link is provided. The back cover stacked below has a bottom stop shaft that locks onto the front cover's shaft and a recess that opens toward the main link insertion hole, and is pushed upward by a spring across the recess and the insertion hole. When the main link insertion hole and the sub link insertion hole match, the fixed pin pressed by the spring moves up the push button and protrudes to the insertion hole, making both links unrotatable. The thickness of the connecting part from the front cover to the back cover is made to be less than three times the thickness of the link.

[Example of idea]

Hereinafter, the structure of the present instigation device will be explained with reference to the drawings of the embodiment. A fixing pin 9 is rotatably and symmetrically supported by a stop shaft 6 that is engaged with the part 4, and is pressed by a spring 8 and is housed between the back cover 5 and the main link tip part 1a.

After making sure that the convex part 27 protrudes and inserting the square shaft 14 of the shaft part 4 into the square hole 12 and the cylindrical shaft 24 into the main link shaft support hole 11, the back is inserted under the main link tip part 1a. Stack the lids 5 and insert the end stop shaft 6 toward the cylindrical shaft 24 of the front cover shaft 4 inserted earlier than the shaft hole 15 of the back cover 5, so that the flange 16 of the end stop shaft 6 is attached to the back cover 5. If it is inserted until it makes contact, the cylindrical shaft 24 will be inserted into the withdrawal hole 26 of the butt stop shaft 6 and protrude downward from the withdrawal hole 26, so the tip of the cylindrical shaft 24 will be opened outward with a tool and the shaft portion 4, the butt stop shaft 6 is irremovably locked to the main link end portion 1a and the sub link end portion 2.
I will support you by going around a.

The main link 1 and the sub-link 2 supported by the shaft part 4 of the front cover 3 and the butt stop shaft 6 which is engaged with the shaft part 4 from the back cover 5 are arranged so that the main link 1 and the sub-link 2 are in a double overlapping state.
The protruding pawl 31 engages with the notch 32 of the sub-link 2, allowing rotation within a range of approximately 180 degrees where both links 1 and 2 are aligned in a straight line. Also, the thickness L of the connecting portion from the front cover 3 to the back cover 5 is within three times the link thickness T.

In the proposed anti-slip device, a pedestal 10 supported at the rear of the main link 1 is screwed to the inner circumference of the window horizontal frame material F, and a seat plate 20 supported at the rear of the sub-link 2 is attached to the shoji horizontal stile B.
When the shoji S is closed, both links 1 and 2 overlap with each other, and as the shoji S swings open from the closed state, the legs open, and the shoji S is completely opened. When opened, it becomes straight, the insertion hole 21 of the main link 1 and the insertion hole 22 of the sub link 2 match, and the fixing pin 9 inserted into the insertion hole 21 of the main link 1 from the recess 25 of the back cover 5 However, the insertion hole 22 of the sub link 2 is inserted by the spring 8.
The push button 7 inserted into the insertion hole 22 is pushed upward, and both links 1 and 2 are unrotatably locked by the fixing pin 9 inserted so that both links 1 and 2 are straddled.

In order to rotate the shoji S, which is locked in a non-swingable manner by the proposed fanning device, in the closing direction, the push button 7 protruding from the front cover 3 is forcibly pressed down with a finger, and the sub link 2 is pressed down. After pushing the fixing pin 9 that had protruded to the insertion hole 22 back to the insertion hole 21 of the main link 1 and releasing the lock between both links 1 and 2, both links 1 and 2 are removed.
Swing the shoji S as if slightly folding the shoji S, and when the fixed pin 9 that has been pushed back cannot be protruded by the rotated sub-link 2, remove your finger from the push button 7 and move the shoji S in the closing direction. It also sways.

It should be noted that the instigation device of the present invention is not limited to the above-mentioned embodiment. For example, if several insertion holes 21 are provided in the main link 1 within the rotation range of the instigation device,
The link can be locked in several stages. Furthermore, the assembly procedure and mounting means of the teasing device are not limited to the above-mentioned embodiments, and both links 1, 2, which constitute the teasing device,
The shapes and structures of the front cover 3, the back cover 5, the push button 7, the fixing pin 9, etc. can be changed as appropriate as long as they do not go against the gist of the present invention.

[Effect of idea]

Therefore, in the proposed locking device, a fixing pin that is pressed in the upward direction by a spring is inserted across the back cover and the main link, and is inserted into the sub link overlapping the main link by the front cover. The push button that cannot be removed is inserted and retracted freely, and when both links are rotated and the insertion part of the fixed pin matches the insertion part of the push button, the fixed pin moves up the push button and inserts the secondary link. Because it protrudes to the inside and locks both links so that they cannot rotate, the locking of the links is strong, and even if the shoji that is supported in the open state by the links is pushed in the opening and closing direction by wind and rain. , the link will not naturally release its lock. Moreover, the link locking structure is simple and can be made thinner than before, so the space between the window frame and the shoji, that is, the installation space for the fan locking device, can be small.
Not only does it become easier to keep the window airtight, but the appearance of the window also improves because the exposure of the blocking device is reduced. In addition, since the locking device of the present invention is in a state where both links are locked by the fixed pins, the push button pushed out by the fixed pins is pressed only when the locking is released and the shoji is swung closed. As all you have to do is push the fixing pins back to the main links, handling is extremely easy, and there is no problem in swinging the shoji open and closed.In addition to the above-mentioned features of the thinner design, this design also allows the shoji to be moved from side to side. As a device for preventing a casement window that swings open and close, it has a practical effect.
