Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is directed to a sliding sash, a single-sliding sash, etc., when opening the outer shoji. This invention relates to a finger jamming prevention device that prevents fingers from being injured by being caught between the fingers.

BACKGROUND TECHNOLOGY The above-mentioned sash finger jamming prevention device is, for example, as shown in FIG.
A fixing piece 100A that comes into contact with the sash 100A is installed, or in the case of the single-pull sash shown in FIG. 14, a stopper 100B is interposed between the outer shoji joining stile 102 and the opposing sash vertical frame.
However, according to these devices, the screen door 10
3, the inner and outer shoji 106 and 107 or 106a and 107 do not overlap, and the
There was a problem with insects entering the room by following the route shown by the arrow in Figure 4. Moreover, when the fixed piece 100A is used in a sliding sash, it is necessary to remove the fixed piece 100A in order to make the inner and outer shoji 106, 107 completely sliding, which makes cleaning the glass difficult. It was troublesome.

In order to solve such problems, for example,
As disclosed in No. 56-12680, it can come into contact with the surface opposite to the outer shoji door frame of the combined mullion for single-sliding sash or the surface opposite to the outer shoji door frame of the inner sash of the sliding sash. A locking body having an abutment and engagement portion is attached to the side stile of the outer shoji so that it can move in and out of the side stile, and a spring is provided to bias the locking body toward the indoor side. There is one in which the abutting and engaging portion is held in a state of protruding toward the indoor side, and the surface of the abutting and engaging portion in this protruding state facing the outer shoji door stop frame is an inclined surface. According to this device, the locking body is constantly protruded toward the indoor side by a spring, so when you want to overlap the outer shoji door end stile and the inner shoji joining stile, or when you want to completely slide them with a sliding sash. If this is the case, the outer shoji must be moved while the locking body is pushed into the horizontal stile by hand, so that the locking body overlaps the inner stile and the stile. In addition, when attempting to close the outer shoji from a state where the outer shoji door leading stile and the inner shoji joining stile overlap or from a completely sliding state, the abutment engagement portion The inclined surface of the inner shoji engages with the stile and the locking body sinks into the stile, so
The problem is that the inner shoji sills are easily scratched, and the shoji has to be closed against the spring force that urges this locking body toward the indoor side, making it difficult to close the shoji. It was hot. In addition, a casing is built into the side stile of the outer shoji, and by moving the locking body built into the casing in the indoor/outdoor direction, it is positioned at a position where it interferes with the other shoji and at a position where it does not interfere. As a result, the dimensions of the casing in the indoor and outdoor directions become large, making it difficult to attach it to the middle part of the door frame of a general sash. Furthermore, since the locking body is built into the horizontal stile (top, bottom stile, and middle stile) of the outer shoji, it is necessary to attach this finger jamming prevention device to the top stile or bottom stile for sashes without middle stile. This means that you have to bend down or stretch your back to operate the locking body.
There was a problem with poor operability.

Means for Solving the Problems The present invention aims to solve the above-mentioned problems, and the present invention aims at solving the above-mentioned problems. A mounting base is provided on either side of the stile so that it does not protrude from the locus of opening/closing movement of the stile, and the base of the locking member is placed on this mounting base at an interference position where its tip faces within the locus of opening/closing movement of one stile. The entire locking member is rotatably supported approximately 90 degrees in a non-interfering position stored in the opening/closing locus of the other stile, and the locking member is further placed in an interfering position between the mounting base and the locking member. The invention is characterized in that it is provided with a holding means capable of holding the position at a non-interfering position.

This window frame is formed by framing 2 and inner and outer shoji door frames 3 and 4, and inner and outer shoji 6 and 7 are slidably fitted into this window frame 5. A is a finger jamming prevention device according to the present invention, and screws are installed on the side surface 9 of the outer shoji door edge stile 8 of the outer shoji 7 in the outer shoji opening direction so that the mounting base 10 does not protrude from the opening/closing movement locus of the outer shoji door edge stile 8. 11. This mounting base 1
As shown in FIGS. 3 and 4, the upper and lower support walls 12a and 12b for mounting a pair of support shafts are formed in a protruding manner, and the base of the locking member 13 is formed between the lower support walls 12a and 12b. 13a is positioned and fitted onto the support shaft 14 so as to be horizontally rotatable and slightly movable in the axial direction. This locking member 13
It is provided with an abutment arm 13b that can abut against the outer shoji door frame facing surface 16. A spring 17 is interposed between the locking member 13 and the lower support wall 12b to urge the locking member 13 toward the upper support wall 12a. The upper support wall 12a has an abutting arm 1.
3b upper surface is the interference position of the locking member 13 (the position where the abutment arm 13b protrudes toward the indoor side from the interior surface 8a of the outer shoji door edge stile 8 and its tip faces into the opening/closing movement locus of the inner shoji door stile 15) (Position P in Figure 5)) The interference position abutting surface 18 and the locking member 1
3 slides in the axial direction at the non-interference position (the position where the entire locking member 13 is accommodated within the opening/closing movement locus of the outer shoji door edge stile 8 (position S in Figure 6)). A step portion 20 is formed with a non-interference position abutment surface 19 in contact with the locking member 13, and constitutes a holding means at the interference and non-interference positions P and S of the locking member 13.

According to such a configuration, by positioning the locking member 13 at the interference position P, the upper surface of the abutment arm 13b is pressed against the interference position abutment surface 18 by the action of the spring 17 and held by friction, so that the outer shoji 7 It does not change its position due to the movement of . Therefore, even if the outer shoji 7 is opened in this state, as shown in FIG. There will be a gap between the two, and your fingers will not be caught between them.

Next, if you want to overlap the inner and outer shoji 6 and 7 or completely slide them, the contact arm 1
3b is rotated by 90 degrees, the entire locking member 13 is pushed upward by the force of the spring 17, and its base 13
a The upper surface is the non-interference position contact surface 1 of the upper support wall 12a

7 can be polymerized or complete sliding can be performed. Furthermore, even when the outer shoji 7 is closed from a completely double-sliding state, the locking member 13 does not come into sliding contact with the inner shoji matching stile 15.
Prevents scratches from occurring. In the following embodiments, the same parts as in this embodiment are given the same numbers, and their explanations will be omitted.

2nd Embodiment In FIGS. 7 to 9, reference numeral 10A is a mounting base, and a support wall 12A is formed protruding from the center of the mounting base 10A in the vertical direction.
A locking member 13A is horizontally rotatably supported with the locking member 13A sandwiching the locking member 13A from both sides, and the locking member 13A and the support shaft 14A can be rotated together by caulking the lower end of the support shaft 14A. It is installed to move. A compression spring 17A is installed inside the support wall 12A, and is in pressure contact with the circumferential surface of the support shaft 14A. Therefore, the indoor side portion of the peripheral surface of the support shaft 14A is constantly pressed against the indoor side peripheral surface of the through hole 12Aa of the support wall 12A, and the locking member 13A includes the interference position P and the non-interference position S shown in FIG. It is designed to be held by friction at any of its rotational positions. According to this configuration, the mounting holes for the screws 11 can be placed above and below the support wall 12A of the mounting base 10A, and the mounting base 10A can be made smaller, thereby preventing the finger jamming prevention device A itself from increasing in size. can.

Third Embodiment In FIGS. 10 to 12, 10B is a mounting base, and this mounting base 10B has a locking member 13B.
is the support shaft 1 whose tip is caulked to the mounting base 10B.
4B, and is configured to rotate within a vertical plane. The mounting base 10B is provided with an abutting wall 12B at its lower part, which abuts against the side surface of the locking member 13B when the locking member 13B is in the interference position (position P in FIG. 11). In addition, the mounting base 10B has a locking member 13B at a non-interference position (11th
When the locking member 13B is in position S), a leaf spring member 17B that presses the distal end face downward is fixedly provided, and the locking member 13B
A holding means is configured to hold the two at an interference position P and a non-interference position S, respectively. According to such a configuration, when the locking member 13B is rotated 90 degrees upward from the interference position P, its tip is pressed by the leaf spring material 17B to maintain the non-interference position S, and from that state When the locking member 13B is tilted horizontally against the pressure of the leaf spring material 17B, the side surface of the locking member 13B abuts against the contact wall 12B and is held at the interference position P.

In the first to third embodiments described above, the finger jamming prevention device was attached to the side surface of the outer shoji door edge stile in the direction in which the outer shoji was opened. The finger jamming prevention device may be attached to the mullion of one of the shoji (opposite surface), or one of the shoji may be fitted, and in that case, the mullion constitutes the stile of the present invention. In addition, the shape of the mounting base was changed as appropriate, and in the second embodiment, the locking member was made to rotate within a vertical plane.
In the third embodiment, the locking member may rotate within a horizontal plane.

Effects of the Invention As described above, in the present invention, by positioning the locking member at the interference position, when the outer shoji is opened, the locking member comes into contact with the matching stile of the inner shoji, and the gap between the two stiles is increased. Accidents such as fingers getting caught can be prevented, and by positioning the locking member in a non-interfering position, the outer shoji can be completely slid.
In addition to making it easy to perform tasks such as cleaning glass, the inner and outer shoji can be completely polymerized, and insects can be prevented from entering even when using a screen door in the summer. Furthermore, even if the locking member is configured to switch between the interference position and the non-interference position as described above, the switching of the locking member may be performed without changing the locking member.
Since this is done by rotating the locking member by 90 degrees, the dimensions of the locking member in the indoor and outdoor directions at the non-interfering position can be reduced, and as a result, it is possible to reduce the size of the door frame and door frame required to attach the locking member. The indoor and outdoor dimensions can be reduced, and it can be installed on the outer surface of the middle part of a general sash frame or door frame, increasing versatility, and can be manufactured easily to reduce costs. . Furthermore, since the locking member is held in a non-interfering position, when the locking member is completely slid, the locking member does not come into sliding contact with the stile of the other shoji, which prevents damage to the stile and prevents the shoji from being damaged. It has the operational advantage that the closing operation can be made extremely light.
