It is possible to prevent the finger from being inserted carelessly into the gap and prevent an accident that the finger is caught. This finger pinch prevention device can be installed in advance at the time of manufacturing the door. However, as described above, the finger pinch prevention device is pivoted to the side of the upper and lower edges of the door, and the door of the door on the shaft suspension side is suspended. Swing doors, which have side edges with a substantially convex arcuate cross-section on their side edges, have been widely used in the past as fittings for toilet booths, etc. The finger pinch prevention device according to the present invention can be installed later. The door 1 that opens to the inside of the toilet booth is as described in this example. However, in the case of a door that opens to the outside of the toilet booth, the device body 10 must be attached to the surface of the door outside the toilet booth before use. You can Further, when the device main body 10 is used for a double-opening door, it can be used by being fixed to both surfaces of the door.

FIGS. 6 to 10 show a second embodiment of the finger pinching prevention device according to the present invention. Door 1, side edge 2, suspension shaft 3, bearing 3a, adjacent wall panel 4, wall side edge 5,
The wall side edge member 7, the side edge member 8, the side projecting edge 9 and the like have the same structure as in the first embodiment. The finger pinch prevention device main body 10 made of metal or hard synthetic resin has a thin plate-shaped rising portion 12 which is formed by continuously connecting an outward L-shaped edge 18 along the surface of the door 1 to a bottom edge 11, and a rising portion. It is formed of a curved surface portion 14 continuously provided from the top edge of the door 12 to the side edge 2 of the door 1 on the axis suspension side of the door 1 up to a position where the leading edge 13 thereof contacts the surface of the door 1. The curved surface portion 14 is formed in an arc shape having a radius of a distance between the axis of the suspension shaft 3 and the side edge 2 of the door 1 on the shaft suspension side. In addition, a fitting concave edge 15 that is fitted to a side projecting edge 9 of the side edge member 8 attached to the side edge 2 of the door 1 that protrudes toward the front surface side of the door 1 is formed on the tip edge 13. An adhesive layer 19 is provided on the rear surface of the L-shaped edge 18 as is apparent from FIG. The adhesive layer 19 is provided by sticking a double-sided pressure-sensitive adhesive sheet or applying an adhesive on site. Device body 10
Is fixed to the opening side of the door 1, but in order to fix the device body 10 to the surface of the door 1, the tip end edge 13 of the curved surface portion 14 is brought close to the side edge 2 of the door 1 on the axis suspension side. Then, the fitting concave edge 15 at the tip edge 13 of the curved surface portion 14 is fitted to the side protruding edge 9 of the side edge member 8. Then, the L-shaped edge 18 continuous with the bottom edge 11 of the rising portion 12 is brought into contact with the surface of the door 1 to remove the L-shaped edge 18
The fastening is completed by adhering the adhesive layer 19 on the back surface to the surface of the door 1. Bottom edge 11 of thin plate-shaped rising portion 12
The L-shaped edge 18 is continuously provided on the adhesive layer 1, and the adhesive layer 1 is provided on the back surface of the L-shaped edge 18.
By adopting the fastening means for applying 9, the finger pinch prevention device can be manufactured at low cost and the fastening work can be performed easily. It is also possible to screw the L-shaped edge 18 to fix the apparatus main body 10.

When the apparatus body 10 is fixed in this way,
As in the first embodiment, the curved surface portion 14 of the apparatus body 10 is the door 1
Of the suspension shaft 3 continuous to the side edge 2 having a substantially convex arc shape in cross section.
The radius of the shaft center of the shaft end and the side edge 2 on the shaft suspension side is substantially the radius, and an arc surface centered on the suspension shaft 3 is formed. Since the door 1 rotates about the suspension shaft 3, the door 1 shown in FIG.
From the open state to the closed state of the door 1 shown in FIG. 10, the wall side edge 5 of the adjacent wall panel 4 and the side edge 2 of the door 1
Alternatively, the gap between the curved surface portion 14 of the apparatus body 10 is maintained in an extremely narrow state in which a finger cannot be inserted, and careless insertion of the finger from the outside G of the toilet booth into this gap is prevented. It is possible to prevent accidents where fingers are caught. This finger pinch prevention device can be installed in advance at the time of manufacturing the door. However, as described above, the finger pinch prevention device is pivoted to the side of the upper and lower edges of the door, and the door of the door on the shaft suspension side is suspended. Swing doors with side edges having a substantially convex arcuate cross-section on the side edges have been widely used in the past as fittings for toilet booths, etc. On the other hand, there is a feature that a finger pinch prevention device can be installed later. The door 1 that opens to the inside of the toilet booth is as described in this example. However, in the case of a door that opens to the outside of the toilet booth, the device body 10 must be attached to the surface of the door outside the toilet booth before use. You can Further, when the device main body 10 is used for a double-opening door, it can be used by being fixed to both surfaces of the door.

[0017]

The present invention has the following effects. A. The curved surface portion of the device main body fixed to the door is continuous with the side edge of the door having a substantially convex arc shape in cross section, and the distance between the axis of the suspension shaft and the side edge on the shaft suspension side is approximately a radius. , Because it forms an arcuate surface centering on the suspension axis, when the door is rotated, from the open state to the closed state of the door, the wall side edge of the adjacent wall panel and the side edge of the door or the curved surface of the device body The gap with the part will be maintained in an extremely narrow state where insertion of fingers is impossible,
It is possible to prevent accidents where a finger is accidentally inserted into the gap from outside the toilet booth and the finger is caught. B. Although the finger pinch prevention device can be installed in advance at the time of manufacturing the door, it has been conventionally mounted on the side edge of the door on the shaft suspension side while being pivoted to the side of the upper and lower edges of the door. Swing doors with side edge members that have a substantially convex arcuate cross-section are often used, and a finger pinch prevention device is installed later on such existing fittings that tend to cause finger pinching accidents. It is possible to C. The finger pinch prevention device is installed and used on the surface of the door in the opening direction, and in the case of a double door, it can be installed and used on both surfaces of the door. D. In a mode in which the rising portion is formed by a pair of parallel plate portions and an insertion hole for inserting the fastening screw is formed in the curved surface portion between the pair of parallel plate portions, finger fastening is prevented by tightening the fastening screw. The device can be securely attached to the surface of the door without being deformed. E. By arranging an L-shaped edge continuously on the bottom edge of the thin plate-shaped rising portion, tightening a fastening screw from above the L-shaped edge, or adopting fastening means for applying an adhesive layer to the back surface of the L-shaped edge, The finger pinch prevention device can be manufactured at low cost and the fastening operation can be easily performed.
