Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a reversal prevention fitting for a rotating window.

[Conventional technology]

The large horizontal rotating window is designed as shown in Figure 3.

The drawing is a side view, and in the drawing 1 is the upper frame, 2
is the lower frame, and 3 is the revolving window.

The rotating window 3 has a rotating shaft 4 in the middle, a guide rail 6 on the outside of one or both of the vertical frames 5, and the end of the tilt stop lever 6a, which has one end pivoted on the horizontal frame, moves to the guide rail 6. It's possible to fit in.

Such a rotating window 3 has a structure in which it can be rotated by a rotating shaft 4 and reversed so that the outside faces the indoor side in order to clean the outside glass surface.

Therefore, when cleaning the revolving window 3 by inverting it, the upper stile 7 of the revolving window 3 is
must be stopped so that the rotating window 3 does not rotate. For this purpose, a reversal prevention fitting is provided on the indoor side of the lower frame 2.

The reversal prevention fitting will be explained below with reference to the side view of FIG.

Reference numeral 2 indicates a lower frame, and reference numeral 8 indicates an inversion prevention metal fitting provided in a hollow portion 9 of the lower frame 2.

This reversal prevention fitting 8 is made up of the following parts. Reference numerals 10 and 11 denote rocking pieces rotatably supported by a shaft 12, and biased upward by a spring 13. 14 denotes these two rocking pieces 10, 11.
This is the stoppage. The end face of the swinging piece 11 is a curved sliding surface 11a, and both swinging pieces 10, 11
A locking portion 15 for locking the upper stile 7 is formed.

Reference numeral 16 denotes a lid for the cavity 9.

According to the above configuration, when the lid 16 is opened, the heads of the two rocking pieces 10 and 11 of the anti-reversal fitting 8 protrude from the cavity 9.

Therefore, when the rotary window 3 is rotated, the upper stile 7 slides on the sliding surface 11a of the swinging piece 11 and is housed in the locking part 15, thereby preventing the upper stile from reversing.

In this state, the outer surface of the glass is wiped, and when cleaning is completed, the swinging piece 11 is lowered with a finger to reverse the rotary window 3 and return it to its original state.

[Problem that the invention attempts to solve]

According to the above-mentioned conventional technology, in a large rotating window, setting a large rotation angle causes unreasonable points such as having to lengthen the guide rail and tilt stop lever, so it is difficult to set a rotation angle too large. I can't take it. As a result, the mounting position of the anti-inversion fitting must be located on the indoor side, and for this purpose, there is a problem that the depth of the lower frame must be made very wide.

[Means for solving problems]

In this invention, one end of a substantially U-shaped support fitting is rotatably supported near the interior surface of the indoor side of a hollow space provided in the lower frame of the window. When the support bracket is raised, a part of the inside of the U-shape comes into contact with and is supported by a support part provided at the indoor end of the lower frame, and is pivoted so that it protrudes from the hollow part to the indoor side, and this support At the other end of the metal fitting, a locking metal fitting having a locking protrusion at its tip is rotatably supported, and a spring provided on the shaft allows the locking protrusion to face the side end surface of the support metal fitting. A locking portion is formed by the side end surface of the support fitting and a locking protrusion of the locking fitting, and the rotating upper stile of the rotating window is locked by this locking portion. It is characterized by the following.

[Effect]

According to the above configuration, when the support metal fitting is rotated on the shaft support, the support metal fitting protrudes toward the indoor side in an arm shape, and the locking part formed by the support metal fitting and the locking metal fitting opens upward, so that the support metal fitting rotates. The upper stile of the rotating window can be locked with this locking part.

In normal times, the supporting metal fittings and the locking metal fittings are stored in the empty space of the lower frame, and when necessary, they are used by protruding toward the indoor side as described above.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

1 is a side view, and FIG. 2 is a plan view. In the figures, 17 is a lower frame, 18 is a hollow part, and 19 is a lid body, which is urged in the opening direction by a spring 20. 21 is a lock knob of the lid body 19, and a lock piece 23 is locked in a locking hole 22 of the lower frame 17.

Reference numeral 24 denotes a reversal prevention metal fitting, which is composed of a support metal fitting 25 and a locking metal fitting 26. The support fitting 25 is rotatably supported on the indoor side of the cavity 18 by a support shaft 27, and is biased by a spring 28 in a direction to protrude from the cavity 18. The locking metal fitting 26 is rotatably supported on the support metal fitting 25 by a support shaft 29, and the locking metal fitting 26
A locking portion 32 is formed between a locking protrusion 30 formed at the tip of the support fitting 25 and a contact portion 31 of the support fitting 25. A curved sliding surface 33 is formed at the tip end up to the locking protrusion 30, and the locking fitting 26
The locking protrusion 30 is urged toward the contact portion 31 by the spring 34, and the distance between the locking portions 32 is maintained by a stopper 35 formed on the locking fitting 26.

A support portion 36 is formed at the indoor end of the lower frame 17 when the support metal fitting 25 is protruded, and the curved portion of the support metal fitting 25 comes into contact with and is supported.

Reference numeral 37 is an upper stile of the rotating window, which is locked to the locking portion 32 described above.

The operation of the above embodiment will be explained below.

Normally, as shown by the chain line in FIG. 1, the anti-reversal fitting 24 is housed in the cavity 18 against the force of the spring 28, and the lid 19 is also housed in the cavity 18 against the reaction force of the spring 20. Close and lock piece 2 of lock knob 21
3 is locked in the locking hole 22.

Then, when the lock knob 21 of the lid body 19 is operated to remove the lock piece 23 from the locking hole 22, the lid body 1
9 is opened by the force of the spring 20, and the anti-reversal fitting 24 also pops out toward the indoor side by the force of the spring 28, and the curved part of the support fitting 25 comes into contact with the support part 36 of the lower frame 17, and the locking part is engaged. 32 opens upward inside the room.

For the reversal prevention fitting 24 in such a state,
When the revolving window is rotated to face the outdoor side of the glass indoors, the upper stile 37 slides on the sliding surface 33 of the locking metal fitting 26, and the locking metal fitting 26 is lifted downward against the force of the spring 34. The stile 37 fits within the locking portion 32 and is supported by being held between the locking protrusion 30 and the abutment portion 31.

After cleaning the glass, use your fingers to release the locking metal fitting 26.
The rotating window can be reversed by lowering , and after being reversed, the reversal prevention fitting 24 is returned to the state shown by the chain line to return to the normal state.

[Effects of the invention] According to the invention described in detail above, when the anti-reversal fitting is normally stored in the empty space of the lower frame, and when it is taken out from the empty area during use, the anti-inversion fitting will move from the lower frame to the indoor side of the arm. By making it protrude in a shape,
This has the effect that when the rotary window is rotated toward the indoor side during cleaning, a large rotation angle close to 180° as in the conventional case is not required. This allows the depth of the lower frame to be reduced.
