Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an optional stopping device for a rotating window that manually slides around a vertical hinge.

[Conventional technology]

Conventionally, the optional stopping means for opening a rotating window that slides around a vertical axis hinge is a connecting rod that is connected to the window and the edge of the opening frame and has a number of holes at appropriate intervals.
Since each operation involves inserting a stop pin or tightening a screw, the connecting rod protrudes in front of the opening frame, detracting from the aesthetics of the area around the window and creating an obstruction, as well as cumbersome operation and wind pressure. Due to the poor stopping function (in the case of screw tightening) and the inability to stop only in a fixed position (in the case of pin insertion), and due to the distance imbalance of the connecting rods, right-angle fenestration was considered impossible.

[Problem that the invention attempts to solve]

Except for special horizontal sliding windows whose vertical axis moves, they can be easily attached to windows that rotate outward from the wall surface around existing vertical axis hinges (fixed position) and their surroundings while maintaining their aesthetic appearance. The early development of a stopping device that can prevent swinging due to wind pressure by stopping at any position with one-touch operation when opening a window, is labor-saving and safe, and can also be opened accurately at a wide angle is the key to the Satsushi industry. This has been a concern for many years.

[Purpose of invention]

The purpose of this product is to eliminate all of the above-mentioned problems, add careful design savings to each component so that it can be made robust and mass-produced at low cost, and provide it to a wide range of markets.

[Means for solving problems]

The optional stopping device for the vertical axis rotating window according to this invention is as follows:
They are slidably fitted into polygonal holes respectively formed in boss parts 3 and 4 bulging on the front and back sides of one side of the chain storage box 2 with one removable lid attached to the lower edge of the window opening frame F. The end portion 7 protrudes from the boss portion 3 on the lid 1 side, and a bullet 12 is interposed between the bottom hole 11 at the other end and the bottom surface of the polygonal hole 5 in the boss portion 4 on the chain storage box 2 side.
And when it is slidably fitted onto the polygonal wall of the chain axle 6 which has upper and lower polygonal walls 8 and 9 in which a circular part 10 with a distance slightly longer than the thickness of the chain wheel 14 is cut approximately in the middle. becomes unrotatable, but on the other hand, its circular part engages the chain wheel 14, which has a polygonal hole that rotates idly, and protrudes and retracts from the chain storage box, and its tip is pivoted to the lower edge of the vertical axis rotation window. It is characterized by consisting of an irreversible chain.

[Effect]

(Window opening) To open a closed window, first press the end of the circular diameter with one hand on the tip side of the chain axle, which has a polygonal wall protruding to one side of the chain storage box. The bullet (push spring) is compressed in the polygonal hole of the boss part that bulges out on one side of the lid and the chain storage box, and then lowers and stops until each coil is in close contact with each other. This is because the circular diameter part (equivalent to the inscribed circle of the polygon) cut a little longer than the thickness of the chain wheel is placed in a position that slightly protrudes from both ends of the polygonal hole of the chain wheel. , the engagement between the chain wheel and the chain axle will be released and both will be in a idling state, so you can push out the window with your other hand,
On the contrary, it is possible to attract. That is, as long as the end of the chain wheel is held down, the irreversible chain that engages the chain wheel can move freely, so the opening and closing operations of the window are not restricted.

(Stop) When you release your hand from the end of the chain axle that was being held down for opening the window, the bullet that had been compressed by the chain axle will recover and expand, pushing the chain axle upward. As the chain axle, which had been idling in the polygonal hole of the chain wheel, rises, the lower polygonal wall slides into the polygonal hole of the chain wheel, and the chain wheel and chain axle are no longer able to idle. The chain axle itself was originally slidably fitted into the polygonal holes in the bosses that bulged into the lid and chain storage box, so although it could be moved vertically, it was completely impossible to rotate. Therefore, the rotation together with the chain wheel comes to a complete stop state.Therefore, when the chain wheel stops, the known irreversible chain that constantly engages becomes immobile, and the window attached to the tip also stops.

The irreversible chain referred to in this invention is a member that can be bent on one side but cannot be bent on the other side, and is a chain storage attached to the lower edge of the window and the lower edge of the window opening frame. Since the window forms a rigid rod-like body and is stretched between the chain wheel engagement part in the box and the window is opened, the window does not swing against the wind pressure and stops reliably, achieving the intended purpose. It is something that

That is, in short, the rotation of the chain wheel is changed by raising and lowering the chain axle with a single touch, so that opening and stopping of the window can be performed at will.

〔Example〕

Figure 1 is an overall schematic view of an embodiment of this invention attached to the lower edge of a window W and the lower edge of a window opening frame F, which rotate around a vertical hinge to the outside of a building or outdoors. 1
A known irreversible chain C is pivotally attached to the lower edge side of the window W through a chain wheel (described later) in the chain storage box 2, which is removably attached with 20 screws.

In detail, as shown in the third, fourth and fifth figures, the lid 1 is removably mounted on the chain storage box 2 with screws 20,
Circular boss portions 3 and 4 bulge out from one side of both, and a polygonal hole 5 is formed in both of them. A chain axle 6 is slidably fitted into the polygonal hole 5.
The upper end 7 is shaped like a dome to soften the feel when pressed and protrudes from the boss 3 of the lid 1, and the lower end is a polygonal wall 8 slightly contracted from the polygonal hole 5 of the boss. 9, and a circular part 10 inscribed in the outline of the polygonal wall is cut in the middle at a distance slightly longer than the thickness of the chain wheel 14, and both ends of the circular part 10 are slope-shaped. The chain axle 6 can be easily inserted into and removed from the chain wheel 14.
A bullet 12 (push spring) is interposed between the bottom hole 11 bored at the rear end and the boss portion 4 of the chain storage box 2, and is slightly compressed from the beginning, and constantly pushes up the chain axle 6. The end portion 7 is made to protrude from the lid 1.

Next, the chain wheel 1 is slidably fitted onto the chain axle 6.
The shaft hole 15 of 4 is slightly larger than the polygonal walls 8 and 9 of the chain axle 6, and the polygonal hole 5 of the boss portions 3 and 4 described above is slightly larger than the polygonal walls 8 and 9 of the chain axle 6.
is equivalent to

The irreversible chain C engaged with the chain wheel 14 moves back and forth in a U-turn shape inside the chain storage box 2, and its tip side is pivotally attached to the lower edge of the window W by a mounting bracket (not shown). There is.

In the figure, reference numeral 17 is a horizontal bearing, which can supplement the smooth rotation of the chain wheel 14.

[Effect of idea]

According to this idea, if the vertical axis hinge is in a fixed position and does not move but rotates outward from the wall, it can be installed as a new window.
It can be easily attached to any existing installation, and with a one-touch operation, the end of the chain axle that protrudes from the box (same function as a push button) can be raised and lowered to open and stop the window at will. In addition to maintaining the aesthetic appearance of the area around the window, such as being able to prevent shaking due to wind pressure during window opening, various effects such as simple and quick operation, safety, and labor-saving can be obtained.
