Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Application Field The present invention relates to a window of a building, particularly a revolving window, and relates to an opening holding device for keeping the revolving window open at a certain angle.

Conventional technology A window with a shoji that rotates around an axis is
It is equipped with an opening holding device for maintaining the rotating state and holding the window in the open state. The simplest version of this open holding device is one in which an arm stay is attached between a vertical frame and a vertical stile, and one end of the arm stay can be fixed with a screw or the like. Since this type of window is inconvenient to handle, a window has appeared that allows the window to be opened at a predetermined opening position by operating a handle (Japanese Patent Laid-Open Publication No.
60−138191).

As shown in FIG. 7, this conventional window opening holding device has a slider 2 that slides up and down on a vertical frame 1, one end of which is rotatably attached, and the other end of which is rotatably attached to a vertical frame 3. Using the attached arm 4,
The slider 2 is held at an appropriate position by a holding means.

As shown in FIGS. 9 and 10, the slider 2 has a cam plate 5 which moves in a direction perpendicular to the sliding direction and is pushed to protrude by a spring.
is provided. This slider 2 is housed in a sliding part formed in the vertical frame 1 as shown in FIG. 10, and is configured to slide therein. Cam plate 5 on wall member 6
Openings 7, 7 are provided for entering. That is,
The position of the slider 2 is maintained by inserting the cam plate 5 into this opening. An opening/closing member 8 for opening and closing the opening 7 is slidably housed on the opposite side of the wall member 6 from the side on which the slider 2 is disposed. This opening/closing member 8 has a handle 11 as a switching means provided in the center of the lower frame 10 of the window.
(Fig. 8) Connecting means 9 which can be moved up and down by
is attached to. The opening/closing member 8 allows the cam plate 5 to be removed from or inserted into the opening 7 by vertical movement of the connecting means, thereby holding the slider 2 in a predetermined position, or allowing it to slide freely.

After all, the holding means for holding the slider 2 at an appropriate position within the vertical frame 1 in this example is constituted by the cam plate 5 of the slider 2, the opening 7 of the wall member 6, and the opening/closing member 8. become. In this example, as shown in FIG. 8, the opening holding device is provided on the left and right vertical frames of the window, but in the case of a small window, either one may be used.

The tip of the cam plate 5 has a chevron shape as shown in the figure so that it can be easily inserted into and taken out from the opening 7, and the opening/closing member 8 is also formed with a recess 8a having the same shape as the chevron shape. When this recess 8a comes to the position of the opening 7, the opening 7 is in an open state.

Problems to be Solved by the Invention Even with the conventional holding device described above, there is no particular problem in terms of the functionality of the holding device itself. Shoji 1 to open and close the window
A handle 14 for moving the lower stile 13 and for pulling the shoji 12 when closing the window must be provided separately from the handle 11 of the switching means. Therefore, as shown in FIG. 8, this window allows the two handles to be seen from the front. Seeing two similar items gives a strange feeling and is not desirable in terms of design.

The present invention has been made in view of these points, and it is an object of the present invention to provide a switching means for a holding device that is not visible from inside the room when the window is closed.

[Structure of the invention] Means for solving the problems The invention will be explained below based on FIGS. 1 to 6, which correspond to embodiments. In the present invention, as shown in FIG. 3, the switching means 21 is housed within the lower frame 20 of the window frame. Therefore, the main body 23 having a rising portion 24 rising from the horizontal portion 22 of the lower frame 20 is fixed to the horizontal portion 22, and the rising portion 24 of the main body 23 is rotated 180 degrees from a substantially horizontal state to a horizontal state on the opposite side. A lever 25 with one end attached as shown in FIG. A rotating cam 26 that rotates together with the lever is attached to this lever 25, and a pin 27 is provided at the end of this rotating cam 26, so that the rotation of the rotating cam 26 by the lever 25 moves the movable plate 28 in the horizontal direction. This is what I did. When the lever 25 is in the horizontal state as shown in FIG. 4, the opening/closing member 8 is not holding the slider 2;
The connecting means 9 is connected to the moving plate 28 so that the slider 2 is held when it is rotated 180 degrees and placed in the horizontal position on the opposite side as shown in FIG.
It is connected to the.

Operation When the window is closed, the lever 25 is in the state shown in Figure 4. The lever 25 is shaped like an elongated plate and is rotated 180 degrees around one end, so if the starting and ending positions of the rotation are horizontal, the switching means 21 as a whole can be The height can be made very low. Therefore, as shown in FIG.
It can be installed in a groove 30 formed in the lower frame 20, and when the window is closed, the switching means 21 including the lever 25 can be hidden from view from the front.

Further, since the moving plate 28 is moved by the rotation of the lever 25, the opening/closing member 8 can be slid up and down by the connecting means 9 connected to the moving plate 28, as in the conventional case, and the opening 7 The cam plate 5 of the slider 2 can be put into the opening 7 and held therein, and the holding can be released.

Embodiment In this embodiment, the slider 2 and the holding means are provided on both sides of the window, so as shown in FIG. , by moving the movable plate 28 in one direction by the lever 25, the left and right opening/closing members 8 are opened.
move up and down in the same direction. If the holding means is provided only on one vertical frame of the window frame, this moving direction changing means 31 is not necessary.

This movement direction changing means 31 is composed of racks 32 and 33 arranged vertically and parallel to each other, and a pinion 34 that engages both racks at the same time, so that when one rack 32 moves, the other rack moves in the opposite direction. is configured to move to. The handle 11 for moving the conventional coupling means 9 is similar to the movement direction changing means 31 of this embodiment, and one rack is moved by rotation of the handle 11. Ta. Therefore, the handle 11 had to be placed outside.

The main body 23 of this embodiment is made of a metal plate having an L-shaped cross section, one side of which is fixed to the horizontal surface 22 of the lower frame 20 with a screw 35 as shown in FIG.
4. The lever 25 is attached to the back side of this rising portion 24, and the rotating cam 26 is attached to the front side. Front and back are relative and have no special meaning. These rotating shafts 36 are common and have a rectangular end so that when the lever 25 rotates, the rotating cam 26 also rotates at the same time.

The moving plate 28 is a rectangular plate, and has a rectangular notch formed in the center thereof, and its sides 37 and 38 are both vertical. The pin 27 is arranged in this notch so as to be in contact with one side 37. As shown in FIGS. 4 and 5, the side 3 is rotated by the rotation of the lever 25 and the pin 27.
The movable plate 28 is moved by pressing against the movable plate 8. Elongated holes 40, 40 are provided at two locations parallel to the moving direction so as to move the moving plate 28 in parallel, and the main body 2
The guide pin 4 has one end fixed to the rising portion 24 of 3.
1 is inserted into this hole 40. Therefore, the moving plate 28 is moved horizontally along this guide pin 41.

The connecting means 9 is connected to both ends of the moving plate 28 via an auxiliary member 42. The connecting means 9, the opening/closing member 8 attached thereto, the slider 2, etc. are conventional ones.

As mentioned above, in this embodiment, the lever 25 is
As shown in the figure, it is always placed horizontally on the left side of the drawing. In this case, the opening 7 is closed by the opening/closing member 8. Therefore, since the cam plate 5 of the slider 2 does not enter the opening 7, it can be opened and closed freely. In other words, the shoji can be opened and closed freely.

When the window is opened by holding the handle 14 of the shoji 12, the switching means 21 can be seen housed in the lower frame 20. When the lever 25 is pulled up and rotated, the rotating cam 26 also rotates, and the pin 2
7 leaves the side 37 of the notch and hits the opposite side 38. When the lever 25 is further rotated to the position shown in FIG. 5, the pin 27 pushes the side 38 and the moving plate 2
Move 8 to the right side of the drawing. This movement causes the connecting means 9 in the left and right vertical frames to move up and down simultaneously via the connecting means 9 and the moving direction converting means 31. In this embodiment, a converting means 43 for converting horizontal movement into vertical movement is provided at the corner of the connecting means 9, but the connecting means may be provided on the vertical frame using an elastic member such as piano wire. Alternatively, it may be directly connected to a vertically moving coupling means.

By this movement of the connecting means 9, the opening 7 and the recess 8a of the opening/closing member 8 are brought into alignment, and the cam plate 5 is inserted therein and held there, as in the conventional case. Conversely, when the lever 25 is rotated to return to its original position and the connecting means 9 is moved to shift the recess 8a of the opening/closing member 8 from the opening position, the tip of the cam plate 5 is chevron-shaped. It is also the same as in the conventional case that the slider 2 comes off the opening 7 and slides freely.

In this way, the slider can be held or released by rotating the lever 25, and the window can be kept open. The shoji can also be closed by rotating the lever 25 in the opposite direction.

[Effect of the invention] As described above, according to the invention, the lever 25 can be
Since it is designed to rotate 180 degrees, the rotating lever is rotated by this rotation, and the movable plate is moved by this rotation, the height in the stored state can be made extremely low, and the lower frame can be moved. Now it can be stored inside. Therefore, when the shoji is closed, there is no need to provide an extra handle on the outside other than the handle for opening and closing the shoji, so the window can be of excellent design.

What's more, all you have to do to hold the window open is to rotate the lever 180 degrees, so even if you lengthen the lever, it won't protrude from the bottom frame. Therefore, since this lever can be made relatively long, it can be easily operated with one hand.
