Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) This invention relates to a revolving window shoji opening position holding device suitable for holding the revolving window shoji at a predetermined opening angle. be.

(Prior Art) Conventionally, as a rotating window shoji open position holding device as described above, there has been one described in, for example, Japanese Patent Application Laid-open No. 138191/1983.

That is, in this rotating window, one end of the arm is pivotally connected to a shoji screen that is rotatably supported by a frame body by a rotating shaft, and is slidably fitted into a sliding groove formed in the frame body. The other end of the arm is pivotally connected to the slider, and a cam plate having an inclined surface formed on the tip side is attached to the slider in a state where it is biased in the projecting direction,
A stop plate having an opening into which the cam plate is fitted is fixed to the side wall of the slide groove, and a stop plate having an opening into which the cam plate is inserted is fixed to the back side of the stop plate, and a stop plate that can be slid up and down by an operation knob is fixed to the back side of the stop plate. A cam receiving block that opens and closes the opening is provided, and the cam receiving block has a V-shaped groove into which the inclined surface of the cam plate is fitted.

Then, when the shoji is rotated to the open state, the cam plate attached to the slider fits into the V-shaped groove from the opening of the stop plate, the shoji is held at a predetermined opening angle, and the cam receiving block is held at a predetermined opening angle. By moving the operating knob up and down, the cam plate of the slider was pushed to release the holding state.

(Problems to be Solved by the Invention) However, in the conventional revolving window shoji opening position holding device described above, in order to be able to hold the shoji moving from the opening direction and the closing direction at a predetermined opening angle, Since the tip of the cam plate has sloped surfaces on both sides, the force that prevents the slide from sliding at a predetermined position is applied in a direction perpendicular to the cam plate. When the shoji opens and closes vigorously, the biasing force of the cam plate overcomes the force of opening and closing the shoji, ensuring that the shoji is held at a predetermined opening angle. The problem was that there were some things that could not be done.

In addition, when holding a shoji at multiple opening angles with respect to the cam receiving block, the entire operation block is slid in the vertical direction to release the fitted state between the cam plate and the V-shaped groove. Even if multiple V-shaped grooves are formed so that the next V-shaped groove and cam plate can be reliably engaged when the cam plate is released, skill is required to operate the operation knob, and operation errors may occur. There are cases where the shoji cannot be held securely, and especially in the case of large shoji, there is a problem in that the person operating the shoji may be harmed.

(Purpose of the invention) Therefore, this invention was devised by focusing on the above-mentioned conventional problems, and was designed to ensure that the shoji can be held at a predetermined opening angle even when the shoji is opened and closed with force. The object of the present invention is to provide a shoji open position holding device for a rotating window.

[Structure of the invention] (Means for solving the problem) The structure of the shoji open position holding device for a revolving window according to this invention to achieve the above object is to attach one end of the arm to the frame of the revolving window or to the shoji. At the same time, the other end of the arm is pivoted to a slider that is slidably fitted into a groove for sliding formed in the shoji or frame of the revolving window, and the arm moves the shoji in an open state at a predetermined angle. In the shoji open position holding device for a revolving window, a pair of locking bodies that can be freely protruded and retracted from the bottom surface of the groove are arranged in the longitudinal direction of the slide groove so that the length of the slider in the sliding direction is fixed. The projecting portions of the pair of locking bodies are provided with stopper surfaces on opposite sides of the pair of locking bodies on which the slides engage, and the opposite sides thereof are provided with stopper surfaces corresponding to the slides. It is characterized in that each of the slides is provided with an inclined surface that sinks the locking body when the slider comes into contact with it.

7a and move together, the engagement between the stopper surfaces 44 of the locking bodies 43, 43 and both end surfaces 28c, 28d of the slider 28 is released, and the slider 28 is moved to the fourth position. It becomes possible to slide downward or upward in the figure, and it becomes possible to change from this state to the open or closed state. That is, the locking body 43,
43 will be interlocked when the slider 28 is opened.

Therefore, as shown in FIG. 1, the glass shoji 1 is provided with holders 40 at positions within the slide groove 27 corresponding to the 45-degree open position and the 90-degree open position, and Locking body 4 of tool 40
3 and 43 operate independently, it is possible to prevent the slider 27 from sliding and hold the arm 26 at the 45-degree open position and the 90-degree open position. Further, the slider 20 can be moved between the pair of locking bodies 43 and 43 by rotating the lever 66 of the operating lever 63 (one-touch operation).
Since they are linked together, they can be easily released.

Further, the locking body 43 has a protrusion 43 at the lower end.
b, 43b is the groove 4 of the insertion hole 47 of the slider 46
7a and 47a, so the slider 4
It does not come out from the insertion hole 47 of 6, and
The inclined surfaces 45, 45 of the pair of locking bodies 43, 43 always face opposite directions without being rotated by the contact of the slider 27.

In addition, although the above-described embodiment has been explained using a horizontal axis rotating window as an example, it is also possible to apply to a vertical axis rotating window.

In addition, in the embodiment described above, the slide groove 2
7 is formed in the auxiliary vertical stile 2a, but
This is a means used to facilitate manufacturing, and the sliding groove 27 may be formed in the vertical frame 2.

Further, in the above-described embodiment, the case where the holder 40 is provided in the sliding groove 27 corresponding to the 45-degree open state and the 90-degree open state of the glass shoji 1 has been described. The position can be determined according to the user's wishes, and the holder 4
The number of attachments of 0 is not limited either.

Furthermore, in the embodiment described above, one end of the arm 26 is pivotally attached to the frame 5, and the other end of the arm 26 is pivotally attached to the slider 28 that is slidably fitted into the slide groove 27 of the shoji 1. I explained what would happen if the
