Description

[Detailed description of the invention] Industrial field of application This application is designed to prevent fingers from being caught between the butt frames of a sliding shoji equipped with a pulling device, or between the door frame and the vertical frame of a sliding sash. This invention relates to a finger jamming prevention device that prevents finger jamming.

Conventional technology When closing an open shoji, or when moving the shoji in the closing direction for a purpose other than its original closing, the person closing the shoji or a third party may carelessly put his or her finger on the stile or vertical frame. If this happens, an accident may occur where a finger gets caught between the stile of the shoji that is being closed and the stile or vertical frame of the corresponding shoji, resulting in injury. These accidents often occur in buildings such as kindergartens and elementary schools where young people who lack the ability to judge situations reside, and safety measures have become a problem.

In order to deal with the above-mentioned accidents, a ``finger jamming prevention device'' has been proposed, which is disclosed in Japanese Utility Model Application No. 170475/1983, which was previously filed by the present applicant. This conventional device is rotatable between a substantially vertical non-interfering position and a substantially horizontal interfering position tilted toward the closing direction of the shoji on the butt stile or door edge stile of a horizontal sliding shoji. Attach the interference member, tilt the interference member in the non-interference position to the interference position due to vibrations caused by the opening of the shoji, and touch the interference member to the butt frame or vertical frame of the corresponding shoji. This is to prevent stuffing.

Problems to be Solved by the Invention According to the above-mentioned "finger jamming prevention device", the interference member that has been tilted to the interference position is brought into contact with the stile or vertical frame of the other party, and the length of the interference member is fixed between the two. Accidents of finger jamming can be prevented by creating a gap corresponding to .

However, in the above-mentioned conventional device, there is no holding means for reliably holding the interference member in the non-interference position, and in order to tilt the interference member from the non-interference position to the interference position, unstable external forces such as vibrations when the shoji is opened are required. Because this is done due to various factors, the interference member may not tilt even if the shoji is opened (in this case, the device will not function unless it is tilted by hand, and if this is not done, the user will forget to operate it). This caused problems in operability, such as not being held in the non-interfering position when desired, but always tilting to the interfering position, making it difficult to close and pull the shoji.

Means for Solving the Problems In view of the above-mentioned shortcomings of the prior art, the present application proposes a sliding door equipped with a slide piece that can be raised and lowered within the stile by operating a handle provided on the butt stile of the shoji or the door edge stile. In a horizontal sliding shoji in which a device operates to draw in and release the shoji, the slide piece has a non-operating position located substantially vertically, and a tilting direction from the position toward the closing direction of the shoji, The lower end of the spacer piece is pivoted by a pivot so that it can rotate freely between the operative position located approximately horizontally, and the spacer piece has a center of gravity that is lower than vertically above the axis when the shoji is closed. It has a shape that deviates in the direction, and its length is set so that when the tip of the spacer piece comes into contact with the opposing shoji member in the operating position, the distance between the opposing tips of the stile to which the spacer piece is attached and the opposing shoji member The spacer piece is set to a length that creates a predetermined gap between the spacer pieces, and the spacer piece is held in the non-acting position by the attraction force of the magnet provided in the stile, and the slide piece is lowered when the shoji is pulled in. Accordingly, the spacer piece is rotated by the rotational force caused by the displaced center of gravity, and is positioned outside the range of action of the magnetic force.

Effect With the above configuration, the spacer piece is reliably held in the non-active position by the attractive force of the magnet, and when the shoji is closed in that state and the handle is then operated to pull the shoji, the spacer piece is When the slide piece descends as the shoji is pulled in, the hold by the magnet is released, and the spacer piece rotates toward the active position due to the rotational force generated by the shifted center of gravity.The next time the shoji is opened, the spacer piece rotates to the active position under its own weight. do.
Unless the spacer piece in the active position is rotated to the non-active position, it will come into contact with the shoji member (butting stile or vertical frame) that faces the stile to which the spacer piece is attached, and there will be a gap between the opposing tips of both members where fingers will not be caught. cause

Embodiments Next, the present application will be described in detail with reference to drawings showing embodiments. As mentioned above, the present application can be applied to all types of horizontal sliding shoji such as draw and double sliding doors, but in the description of the embodiments, the case where the present application is applied to draw doors will be explained.

In FIG. 5, reference numerals 1 and 1a are fitted doors fitted into both sides of a window frame 103, and two butt shoji shoji 2 and 3 (hereinafter referred to as shoji) are built into the window frame 103. By dividing this into left and right, shoji 2,
3 is released. In Figure 2, 6, 7
are butt pads provided on the outdoor side of the butt frames 4 and 5 of each shoji 2 and 3, and 8 and 9 are batten boards,
This is to cover the butt part when the shoji 2 and 3 are closed. Finally, 11 and 11a are slide pieces that constitute a part of the pulling device 10, and the butt frames 4 and 5
The shoji 2 and 3 are installed in the interior of the shoji so as to be slidable in the vertical direction in FIG. The device 10 is designed to maintain airtightness by pulling the device 10, for example.
-10654, or JP-A-58-135281, etc.
Since the device is suitably adopted from a conventionally known device, its details will be omitted.

In the draw door as described above, the finger jamming prevention device 13 of the present invention is constructed as follows and operates as follows.

Reference numeral 15 denotes a mounting base for a spacer piece 14, which will be described later.As is clear from FIG. The lower end of the spacer piece 14 is rotatably attached to the mounting plate 16 of the mounting base 15 via a pivot 17.

As is clear from FIGS. 1 and 2, the spacer piece 14 has a box-shaped cross section with an open top surface, and when it reaches the operating position where it is held substantially horizontally as shown by the solid line in FIG. , end surface 18 of bottom plate 18
a hits the mounting plate 16 and subsequent rotation is restricted. That is, the spacer piece 14 is located between the above working position and the first
As shown by the imaginary line in the figure, the slide piece 11 prevents further rotation, and the slide piece 11 can freely rotate between a non-operating position where the slide piece 11 is held in a substantially vertical position.
Moreover, the spacer piece 14 is as shown in FIG.
The part below the imaginary line The spacer piece 14 is deflected, and a force acts on the spacer piece 14 to rotate it counterclockwise in FIG. 19
is an adsorbent made of a magnetic material embedded in the bottom plate 18 of the spacer piece 14, and protrudes from the upper surface of the spacer piece 14 by an amount corresponding to approximately the thickness of the slide piece 11. Further, 20 is a buffer attached to the front end of the spacer piece 14. Then, when the spacer piece 14 is in the operating position and the shoji 2, 3 are closed and the buffer 20 at the tip comes into contact with the pedestal 24, which will be described later, the spacer piece 14 is at the tip of the butt stile 4, 5 as shown in FIG. The length is set so that there is a gap between them so that your fingers won't get caught.

21 is a through hole bored in the slide piece 11;
When the spacer piece 14 is held in the non-operating position, the adsorbent body 19 is positioned so as to face it. Next, a magnet 22 is attached to the partition wall 23 of the butt frame 4 and attracts the adsorbing body 19 of the spacer piece 14 in the non-active position to hold the spacer piece 14 in the non-active position. The length of the magnet 22 below the point of attraction with the attraction body 19 is set to be shorter than the sliding stroke of the slide piece 11. The last part 24 is a pedestal, which is attached to the slide piece 11a on the other butt stile 5 corresponding to the butt stile 4.

If the shoji 2, 3 are closed when the spacer piece 14 is in the operating position, the front end buffer 20 of the spacer piece 14 will come into contact with the pedestal 24, preventing complete closing, and as shown in FIG. , 9 and the butt frames 4, 5, there will be no accident of fingers getting caught due to intentional or unintentional closing of the shoji 2, 3. When closing the open shoji 2, 3, the spacer piece 14, which is in the working position as shown in Fig. 4A, is pushed up by hand to the non-working position as shown in Fig. 4B. , the implanted adsorbent 19 faces into the through hole 21 and is adsorbed by the magnet 22. Therefore, when the shoji 2 is closed, the spacer piece 14 does not rotate to the working position due to vibrations or other impacts, and is closed while maintaining the non-working position, as shown in FIG. 4C. It faces the pedestal 24 with a predetermined interval. Next, when the handle 12 is operated, the slide pieces 11 and 11a slide downward (the area above the handle is upward), and the shoji 2 and 3 are pulled together by the action of a pulling piece (not shown) of the pulling device 10. At this time, as the slide piece 11 descends, the adsorbent 19 moves towards the magnet 2.
The spacer piece 14 moves downward while descending relative to the surface of the spacer 2. Since the length of the magnet 22 is set as described above, when the attracting operation is completed, the spacer piece 14 is released from the attraction by the magnet 22, and furthermore, due to the displaced center of gravity of the spacer piece 14, the spacer piece 14 is moved in the direction of the action position. It rotates due to the rotational force, and reaches a state where it leans against the pedestal 24 as shown in FIG.

When opening the shoji 2, 3, the previously operated handle 12 is returned to its original position, and this operation causes the spacer piece 14 to rise again to a position corresponding to the magnet 22, as shown in FIG. 4E. However, as described above, the spacer piece 14 is rotated outside the range of action of the magnetic force, so it is not attracted by the magnet 22, and when the shoji 2 and 3 are opened, it is reliably rotated to the action position, preventing accidents. Do this. No forgetting of operations occurs.

In the above embodiment, the spacer piece 14 is attracted by the magnet 22 by the adsorbent 19, but a magnet with strong magnetic force may be used to attract the spacer piece 14 through the slide piece 11. The contact is not limited to the pedestal 24,
It may be brought into direct contact with the butt frame 5. Furthermore, when the device of the present invention is applied to a sliding sash, the device of the present invention is attached to a door frame, and the spacer piece 14 comes into contact with the vertical frame 103a.

Effects of the Invention As detailed above, according to the finger jamming prevention device of the present invention, the spacer piece rotated to the inactive position is reliably held at that position by the magnet.
Since the shoji does not fall to the working position when the shoji is closed, the shoji can be smoothly closed and pulled. In addition, in horizontal sliding shoji with a pulling device, when the operator normally performs the operation when closing the shoji, that is, when the slide piece descends as the shoji is pulled in, the spacer piece is released from being held by the magnet. As a result, the spacer piece moves away from the inactive position and rotates toward the active position due to the rotational force caused by the displaced center of gravity, and when the shoji is opened, it automatically rotates to the active position. , the operator does not have to be conscious of the operation of rotating the spacer piece to the working position at all, and it is possible to reliably prevent the so-called forgotten operation from occurring, and to prevent the shoji from being closed inadvertently. Abbreviation for finger pinch accidents
100% preventable.
