Description

The present invention relates to a technique for preventing finger pinching in a hinged door that prevents a finger from being caught in a gap between a door body and a frame body in a hinged door attached to an opening of a building such as a house, an apartment, or a building. Belongs to the field.

Conventionally, there is known a hinged door provided with a door body that can be opened and closed around a vertical axis between vertical frames erected on the left and right sides. A large gap S is formed between the vertical frame on the suspender side, and there is a risk that fingers may be pinched if the door is closed with fingers placed in the gap S. In particular, when a hinged door is installed at the entrance of a residence, a hand is attached to the vertical frame on the suspender side in order to maintain the balance of the body when footwear such as shoes is attached / detached. There is a possibility that fingers will enter.
Therefore, in order to avoid such finger pinching, as shown in Patent Document 1, in the closed state of the door, a safety space having at least a gap of a width in which a finger can be loosely fitted is formed between the suspension side vertical frame and the door. Something like that has been proposed.
Further, as shown in Patent Document 2, a short piece rotor blade comprising a short piece rotor blade and a long piece rotor blade and having a helical coil spring fitted to the hinge shaft is fixed to a mounting seat, and the long piece rotor blade is rebounded by the repulsive force of the coil spring. There is one that covers the gap formed on the suspending side when the door is opened by causing the leading edge of the door to contact the back surface of the door following the rotation of the door.

In the hinged door provided with a flexible door body, a handle member is provided on the hanging side vertical frame of the vertical frame so as to be located on the indoor side.
According to a second aspect of the present invention, the handle member is composed of a support side projecting in the left-right direction and a handle side provided at the tip side of the support side and facing the vertical direction, and the handle side is when the door body is fully closed. The door body inner plate is provided with a gap having a dimension larger than at least the thickness of the finger.
According to a third aspect of the present invention, in the second aspect, the handle side of the handle member faces the gap formed by the hanging end side end surface of the door body and the hanging side vertical frame when the door body is opened. Is provided.
Further, the invention according to claim 4 is the invention according to claim 2 or 3, wherein the handle member has an upright posture in which the support side is positioned substantially parallel to the inner surface of the door body when the door body is closed, and the support side is substantially the same as the inner surface of the door body. It is characterized in that it is configured to be able to rise and fall in a lying posture that is located at a right angle and falls to the indoor side.

According to the first aspect of the present invention, for example, when it is necessary to support the body at the doorway, the fingers are not pinched by gripping the handle member provided on the hanging side vertical frame.
According to the invention of claim 2, even when the door body is opened and closed while the handle side is gripped with fingers, the fingers are not caught in the gap between the handle side and the door body, and safety is improved. To do.
By setting it as invention of Claim 3, insertion of a finger to the gap | interval formed with the suspension base side end surface and suspension base vertical frame of a door body at the time of a door body open | release can be prevented effectively.
According to the invention of claim 4, the entrance / exit opening width is not narrowed more than necessary by setting the handle member to the lying posture.

Next, embodiments of the present invention will be described with reference to the drawings.
In the figure, 1 is a hinged door built in a housing opening, and the hinged door 1 includes an upper frame 2, a lower frame 3, a suspension-side vertical frame 4, and a lock-side vertical frame 5 formed by bending a steel plate. A door body 6 is supported by a hanging vertical frame 4 via a hinge 7 so that it can be opened and closed around a vertical axis.

While the hanging side vertical frame 4 is bent at one end side of the indoor side finding side 4a and the outdoor side finding side 4b facing each other in the indoor / outdoor direction to form the body side sides 4c and 4d, On the other end side, an indoor side expected side 4e which is located on the indoor side and faces the outside of the room, and a connecting side 4f which is bent and bent at the end of the expected side 4e and extending to the housing side sides 4c and 4d are formed. Further, the connecting side 4f is bent integrally with an expected outdoor side 4g extending from the other end of the outdoor side 4b.
The door body 6 is formed by disposing an inner surface plate 6a positioned on the indoor side and an outer surface plate 6b positioned on the outdoor side and arranging a core material 6c between the both surface plates. Further, the end portions of the inner surface plate 6a and the outer surface plate 6b are bent to face each other, and the suspension end surface 6d.
Is formed and supported by a hinge 7 attached to the suspension side end surface 6d of the door body 6 and the outdoor side expected side 4g of the suspension side vertical frame 4 so as to be movable around the vertical axis.

8 is a handle member, and the handle member 8 is configured in a substantially U shape in front view with upper and lower support sides 8a and 8a and a handle side 8b connecting the support sides 8a and 8a. A hole 8c penetrating in the vertical direction and two recesses 8d and 8d disposed at a right angle to the center of the hole 8c are formed on the tip side of the sides 8a and 8a.

On the other hand, 8e is a mounting seat to which the upper and lower support sides 8a, 8a of the handle member 8 are respectively mounted, and the mounting seat 8e is provided with a munition for biasing a ball provided on the tip side in the protruding direction. A stopper 8f is internally provided. The upper and lower support sides 8a are mounted on the mounting seat 8e so as to be rotatable by the support shaft 8g in the holes 8c of the mounting seat 8e. In this state, the stopper 8f is elastically fitted into the recess 2d of the support side 8a. As a result, the support side 8a is configured to freely change between a standing posture and a lying posture at an angle of 90 degrees with respect to the mounting seat 8e.

The handle member 8 is fixed to the indoor side expected side 4e of the hanging side vertical frame 4 with a screw or the like (not shown) with the handle side 8b facing in the vertical direction, and the handle side 8b is a door when closed. An upright posture that is substantially parallel to the body 6 and a tilted posture that is substantially perpendicular to the door body 6 by rotating inwardly about the support shaft 8g. When the handle member 8 is in the lying down position, as shown in FIG. 6, when the door body 6 is rotated 90 degrees around the hinge 7 as shown in FIG. 6, the handle member 8 is opened from the extension line XX of the inner surface plate 6 a of the door 6. Thus, the opening width dimension is not reduced by the handle member 8 even when, for example, a large load is carried in / out from the opening.
In the standing posture, as shown in FIG. 2, the gap W between the inner surface plate 6a of the door body 6 and the outer side surface of the handle side 8b when closed is set to be at least larger than the thickness of the fingers. Thus, even when the door body 6 that has been opened with the handle side 8b held by the hand is closed, fingers are not caught in the gap W.

FIG. 5 is a state diagram showing when the door body is opened in FIG. 2, and the gap S formed between the hanging side end face 6 d of the door body 6 and the outdoor side expected side 4 g of the hanging side vertical frame 4. However, the handle side 8b on the distal end side of the handle member 8 is set so as to be located in the space facing the gap S when viewed in the room. By adopting such a configuration, the handle side 8b is positioned inside the opening S inside the gap S, and the gap S is prevented by the psychological action of preventing the fingers from entering the gap S and grasping the handle side 8b. It is possible to effectively prevent a finger from being caught between the fingers.

In the above embodiment, the handle member 8 is configured to be tiltable. However, the handle member 8 may be a fixed type that does not have a tilting function like a general handle. Needless to say, the handle side 8b extending in the vertical direction may be provided at the tip of the support side 8a so as to have a T shape when viewed from the front.

The present invention configured as described is suspended by a very simple configuration in which a handle member 8 is provided on the indoor side of the suspension side vertical frame 4 when, for example, it is intended to maintain the balance of the body when footwear is attached or detached at the entrance. Since the handle member 8 is gripped instead of the original vertical frame 4, the danger of pinching fingers in the gap S between the door body 6 and the hanging vertical frame 4 can be avoided. Can also be installed easily.
