Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a case where the present invention is applied to a normal type double-sided flush door. The door 1 has an outer surface plate 3 and an inner surface plate 4 attached to the outer surface and the indoor surface of the upper and lower, left and right force bones 2 respectively. The outer surface plate 3 and the inner surface plate 4 are formed with locking bulges 3a, 4a which are bent back in a curved shape at the respective tips protruding from the widthwise kinematic bones 2, 2, so that the kinematic bones 2, 2 are formed. The portion bent along the width direction is fixed by screws, pop rivets, and the like. In the door 1, a curved ridge member 5 formed by a substantially semicircular arc curve in a plan view fits in the entire recess in the concave space between the hanging bulges 3 a and 4 a on the suspension side. It is installed in the state where it was combined. On the other hand, in the concave space between the locking bulges 3a and 4a on the door end side, a U-shaped decorative cover 6 in a plan view is attached in a fitted state.

The door 1 is rotatably fitted to the upper and lower door frames 9A and 9B by pivot hinges 7 and 8 at the upper end surface and the lower end surface on the hanging side. As shown in FIG. 4, the upper pivot hinge 7 has a receiving member 7A having a circular hole held below the upper end surface of the door 1 and an upper door frame 9A.
Member 7C having a circular hole attached to the upper surface of
The movable member 7 fitted in the circular hole of the guide member 7C and slid in the vertical direction,
E. The receiving member 7A is formed so as to protrude downward from one end of the mounting substrate 7B. The mounting substrate 7B is provided with a through-hole of the same size as an extension of the circular hole of the receiving member 7A, and the other parts are illustrated. Multiple like 6,
For example, it is attached to the upper end surface of the door 1 by three countersunk screws 10. In this mounting, when the receiving member 7A overlaps with the upper end surface of the door 1, it is necessary to provide a hole in the upper end surface of the door 1 into which the receiving member 7A can be inserted. The hole provided on the upper end surface of the door 1 by being housed in the door 1 may be omitted.

The guide member 7C is formed so as to protrude upward from one end of the guide member mounting board 7D. The mounting board 7D is provided with a through hole as an extension of the circular hole of the guide member 7C. Is attached to the upper surface of the upper door frame 9A by a plurality of, for example, four countersunk screws 11, and housed in the upper door frame 9A. The guide member 7C is provided with an elongated hole 7c that reaches a circular hole in the longitudinal direction of the outer peripheral surface on the mounting board 7D side. On the upper surface of the mounting board 7D, the middle part of the lever 12 is pin 1
4 pivotally support the vertical support members 13. One end of the lever 12 is rotatably connected to the movable member 7E through the elongated hole 7c of the guide member 7C, and the other end of the lever 12 is a spherical surface at the upper end of the universal joint member 15 which is screwed with the mounting board 7D and protrudes upward. It is connected to the department. Universal joint member 1
5 is provided with a groove 15a for rotation operation at the tip on the screw side. In the lever 12, the length from the pin 14 to the center line of the guide member 7C is set to, for example, about 3.5 to 4 times the length from the pin 14 to the universal joint member 15.

On the other hand, the lower pivot hinge 8 is
A locking projection 8B rotatably held with respect to the main body member 8A fixed to the lower door frame 9B, and a hole 8b attached to the lower end surface of the door 1 and capable of engaging with the locking projection 8B. And a receiving member 8C with a substrate provided. Locking projection 8 in this case
B has a non-circular shape in which both ends in one direction of a circular axis are cut inward by two flat surfaces inclining upward, and a vertical section in a direction perpendicular to the cut surface is trapezoidal. It has become. Therefore, when the locking projection 8B and the receiving member 8C are engaged with each other, the two do not integrally slide and the door 1 smoothly rotates with respect to the main body member 8A. On the upper surface of the main body member 8A, a plurality of, for example, four countersunk screws 16 are attached. The receiving member 8C is formed so as to protrude downward from one end of the mounting substrate 8E. The mounting substrate 8E is provided with a non-circular hole having the same shape as an extension of the hole of the receiving member 8C. Is attached to the lower end surface of the door 1 by a plurality of, for example, four countersunk screws 17.

The curved ridge member 5 of the door 1 is such that the first gap 51 between the door frame 9C in the vertical direction on the hanging side is greater than the thickness of the finger at any rotational position when the door 1 is opened and closed. Is set to a set size that is slightly smaller, for example, about 5 mm or less. In the inner surface plate 4 of the door 1, the second gap 41 between the upper end 92 of the groove wall 91 of the packing groove 9 c on the hanging side and the second gap 41 between the door frame 9 C in the vertical direction and the curved ridge member 5 are formed. It is formed so as to have almost the same size as one gap 51.

The upper and lower sides of the hanging side of the door are rotatably connected to the upper and lower door frames by a pivot hinge at substantially the center of the door thickness, and the curved ridge member 5 and the door on the hanging side are connected. When each gap between the frame 9C and the inner surface plate 4 and the upper end 92 of the groove wall of the packing groove 9c on the hanging side is set to such a narrow dimension, the door 1 can be opened and closed at any position. However, since these gaps are kept to a size that does not allow a finger to enter due to the function of the surface of the curved ridge member 5 that rotates together with the door 1, a finger is likely to enter these gaps, When it is hung, the danger can be easily detected by the tactile sensation to the fingertip, and the finger stuffing in these portions can be prevented in advance. Also, the inner surface plate 4 of the door 1
The upper end 94 of the groove wall 93 of the packing groove 9d formed in the vertical door frame 9D on the door tip side is positioned at least at the center in the vertical direction between the inner surface of the door and the door when the door is closed. The recess 95 is formed by forming the recess 95 to be slightly smaller than the thickness.

When the recess 95 is formed so as to include at least a range from a fingertip to a top when a person stands in front of the door and lowers his / her hand, for example, the center excluding about 30 cm above and below the door frame. Formed in parts. Alternatively, it is fully extended to a position where it comes into contact with the packing groove wall of the upper frame and the lower frame (in this case, the concave portion of the groove wall of the packing groove on the door end side is formed not by cutting off the groove wall but by integrally bending. ) The finger jam prevention range may be expanded. The third gap 43 between the upper end 94 of the groove wall 93 in the portion where the concave portion 95 is formed and the inner surface plate of the door when closed is set to a size slightly larger than the thickness of the finger, for example, It is determined to be about 8 to 17 mm. The packing groove 9d on the door end side in the portion where the concave portion 95 is formed has a smaller depth than the conventional packing groove e, but the hermetic packing 18 is adhered to the packing groove 9d and is sufficiently prevented from coming off. .

Since the gap 43 between the inner surface plate 4 of the door 1 and the upper end 94 of the groove wall of the packing groove 9d on the door tip side is determined to have a set size that is slightly larger than the thickness of the finger. Even when the door 1 is closed without knowing that a finger is inserted into the gap, the finger is kept in contact with the door 1 and the packing groove 9.
There is no danger of receiving a strong pressing force with the upper end of the groove wall of d. In the above-described embodiment, the case where the door frame 9 includes the lower door frame 9B has been described. However, when the present invention is applied to the gate-shaped door frame 9, the door frame 9 is attached to the lower door frame 9B in the above-described embodiment. The lower pivot hinge 8 is attached to the floor surface, and the floor surface forms a lower door frame.

FIG. 10 shows another embodiment of the present invention, in which the present invention is applied to an earthquake-resistant door resistant to earthquakes. In this case, the door-side power bone 2A has a Z-shape in which one side of the U-shape is bent toward the defeated side, and the door-side end face of the door 1A whose interval is widened by the bent portion to the opposite side. The gap between the door frame 9D and the vertical door frame 9D is not visible from the outside. In this configuration, a finger is prevented from entering a gap between the curved ridge member 5 and the vertical door frame 9C or a gap between the door 1A and the packing groove 9c on the hanging side, and the door 1A on the door end side. Not only can a finger not be pressed in the gap between the groove and the packing groove 9d, but also the door 1A can be easily opened even when the door is deformed due to an earthquake.

[0015]

According to the present invention, the following excellent effects can be obtained. In the door for preventing finger stuffing according to claim 1, the thickness of the finger between the inner surface of the door and the inner surface of the door when the door is closed is provided at least at the center in the vertical direction of the groove wall of the door-side packing groove of the door frame. Since the recess is set to be slightly larger, even if the door is closed due to sudden wind, etc., the gap between the door-side packing groove of the door frame and the inner surface of the door Even when a finger is pinched, the pressing force does not act on the finger, so that the occurrence of injury due to finger stuffing can be prevented.
