Description

[Detailed description of the invention] [Purpose of the invention] "Industrial application field" This invention relates to a pulling device installed in the opening/closing device of casement windows such as outward-hinging windows, inward-hinging windows, and sliding windows. be.

``Prior Art'' Conventionally, as a casement window opening/closing device, the U.S. Patent No.
There is a switching device disclosed in the specification of No. 2767979. This is illustrated in the drawings as shown in FIGS. 7 to 10.

In the figure, a handle 3 is pivotally supported on an operating section main body 2 fixed to a lower frame 1a of an opening frame 1, and a worm 5 is provided on a shaft 4 of the handle 3. Inside the main body 2 of the operating section are a pair of arms 7, each having gears 6, 6' that engage with each other at the base.
7' is pivotally mounted, and the worm 5 meshes with one of the gears 6.

A shoji 9 is attached to the vertical frame 1b of the opening frame 1 via a hinge 8.

The shoji 9 has a guide groove 10 of a rail 10 fixed to the lower stile 9a of the shoji 9 along the longitudinal direction of the lower stile.
The opening and closing of the arms 7 and 7' are supported by the arms 7 and 7', which have rollers 11 and 11' at their tips that engage with the arms 7 and 7'.

When the handle 3 is rotated, the worm 5 rotates a gear 6 that meshes with the worm 5. The gear 6
The rotation of the gear 6 rotates the other gear 6' that meshes with the gear 6, and the gears 6 and 6' rotate in opposite directions. As the gears 6, 6' rotate, the arms 7, 7' integrated with the gears 6, 6' move in opposite directions while engaging the rollers 11, 11' at the tips with the guide grooves 10a of the rail 10. The lower end of the shoji 9 is rotated toward the outdoor side to open the shoji 9.

When the shoji 9 is closed, the shoji 9 closes to the lower stile 9a of the shoji 9 by performing the reverse operation described above.
The rail 10 fixed to the opening frame 1 is housed in the groove 12a formed by the frame 12 fixed to the lower frame 1a of the opening frame 1, and the opening frame 1 is closed.

``Problems to be solved by the invention'' In the casement window described above, when closing, the lower stile 9a of the shoji 9 and the lower frame 1a of the opening frame 1 are strongly pulled together by the rotation of the arms 7, 7'. However, since the upper part of the shoji 9 and the opening frame are pulled together only by the hinge 8, when a load from the outdoor side is applied to the shoji, the upper stile of the shoji 9 and the upper part of the opening frame 1 are pulled together. There is a problem in that a gap is created between the frame and the frame.

Such a problem is not limited to the above-mentioned sliding window, but also applies to windows that swing outward or windows that swing inward using this opening/closing device.

As a means to solve this problem, it is possible to separately provide a manually operated puller at the top of the window, but this is cumbersome as the puller must be operated every time the shoji is opened or closed.

This idea focuses on the above-mentioned problems with conventional casement windows, and when the shoji is closed, the shoji is automatically pulled in as the shoji is closed, and as the shoji is opened, the shoji is automatically released. The purpose of this invention is to provide a shifting device.

[Structure of the idea]

"Means for Solving the Problems" This invention solves the problems described above by using the conventional switchgear mentioned above and providing the switchgear with a pulling device that interlocks with the switchgear. .

That is, this device consists of an opening shoji and an opening frame for storing the opening shoji, and has a pivot between the vertical stile of the shoji and the vertical frame of the opening frame corresponding to the stile, and An arm is attached to the base of the lower stile of the opening shoji, which uses the branch as a fulcrum and has a roller pivotally attached to its tip, which engages with a guide groove of a rail provided over the entire longitudinal length of the lower stile. A gear formed integrally is engaged with a worm of a handle arranged in an operating part main body fixed to an opening frame side, and the arm engages the roller along a guide groove by rotating the handle. In a single-hinged window configured to open and close the shoji by rotating the shoji, the arm has a roller pivotally attached to the tip thereof, and a stop protruding downward is fixed near the roller. A recess into which the roller fits in the closed position of the opening shoji is formed in the side wall of the guide groove of the rail in which the roller is engaged and guided, and the roller fits into the rail guide groove in the closed position of the opening shoji. When inserted into the recess of the roller, the stopper fixed near the roller is rotatably supported by a pin erected on the lower frame of the opening frame corresponding to the lower frame, and always rotates in the direction of rotation. The piece is configured such that the spring force comes into contact with the hook portion of the biased piece to rotate the piece around the pin against the spring force, and one end of the cable is pivotally connected to the piece. At the same time, the other end of the cable extends from the lower frame of the opening frame along the vertical frame, and is pivotally connected to a latch having an engaging hook portion rotatably connected to the vertical frame, and is pivotally connected to a latch having an engaging hook part that is rotatably connected to the vertical frame. At the time of closing, the roller fits into the recess of the rail guide groove, and the lock comes into contact with the piece, causing the piece to rotate around the pin against the spring force. The engaging hook part is engaged with a receiver fixed to the vertical stile of the opening shoji corresponding to the latch to draw the opening shoji toward the opening frame, and when the opening shoji is opened, the rollers are moved into the rail guide groove. By escaping from the recessed portion, the contact between the corresponding piece and the piece is removed, and the piece is rotated around the pin by the spring force, and the engagement between the latch and the receiver is released. This is a pulling device for single-hinged windows.

"Operation" (When closing the shoji from the open state) Rotate the shoji to the closed position by rotating the handle. In the closed position, by further rotating the handle, the roller engaged with the guide groove of the rail, which is pivotally attached to the upper surface of the tip of the arm that supports opening and closing of the shoji and fixed to the lower stile of the shoji, moves to the side wall of the guide groove. It fits into the recess formed in the part. By fitting the roller into the recess, the shoji presses the opening frame in which the shoji is housed, and the dowel protruding downward and fixed near the roller on the lower surface of the arm is rotatable to the lower frame of the opening frame. The attached piece is pressed, and the piece is rotated around the pin axis against the spring force applied to the piece. As the piece rotates, the cable that connects the piece and the latch moves, and the movement of the cable causes the latch to rotate around its axis, and the latch connects the engaging hook to the receiver fixed to the stile of the shoji. When engaged, the shoji is drawn into the opening frame.

(When opening the shoji from the closed state) By rotating the handle in the opposite direction to the above, the roller pivotally attached to the arm escapes from the recess formed in the side wall of the guide groove of the rail.

As the roller escapes from the recess, the arm to which the roller is pivoted rotates toward the open side while engaging the roller in the rail guide groove, and at the same time, the contact between the stopper fixed to the arm and the piece is released. As a result, the piece rotates around the pin axis in the direction toward the stopper due to the spring force applied to the piece. As the piece rotates, the cable connecting the piece and the latch pivotally attached to the vertical frame of the opening frame moves, rotates the latch around its axis, and fixes it to the engaging hook part of the latch and the shoji vertical frame. The shoji is disengaged from the received receiver, and the shoji is rotated to the opening side to be opened.

As the piece 27 rotates, the cable 29 connecting the piece 27 and the latch 31 pivotally attached to the vertical frame 17b of the opening frame 17 is pulled upward by the spring force and moves, and the cable 29 and other parts are pulled upward by the spring force and moved. The latch 31, whose end is pivoted, rotates clockwise around the axis, and the engaging hook portion 31a of the latch 31 rotates clockwise around the axis.
The engagement with the receiver 36 fixed to the shoji frame 13b is released, and the drawn state of the shoji 13 is released.

[Effect of idea]

Since the pulling device of this invention is pulled and released in conjunction with the opening/closing operation of the shoji opening/closing device, there is no need for a separate manual pulling device, and the complexity of operation can be eliminated.

Further, since the shoji is tightly housed within the opening frame by the pulling device, even if a load is applied to the open side of the shoji in the closed state, no gap will be created between the shoji and the opening frame.

Pulling is first performed at the bottom frame of the opening frame, and after this pulling is completed, pulling is performed at the top of the opening frame, so the pulling force is dispersed, and the pulling is done evenly without straining the operation. It will be done.

Since the cable separates the pulling tool such as a latch holder from the driving side consisting of the stopper and the piece, the driving side can be attached to the pulling tool at an appropriate location.
