Description

The present invention relates to a door device that opens and closes an opening by rotating a door member.

Conventionally, this type of invention has been provided with a rotating door body and a door bottom side frame member facing the door bottom portion of the door body, as described in Patent Document 1, for example. A finger pinch prevention part having a cross section of a broken line shape having two bent parts is provided protrudingly on a portion of the outer side surface of the target space on the door end side, and a tip portion is made to protrude from the door end side frame material. There is a door with a meeting room.
In this prior art, the gap formed between the finger pinch prevention part and the joining part is made relatively small while the door body is pivoted in the opening direction.

Japanese Patent Application Publication No. 2018-53636

However, according to the above-mentioned conventional technology, as the door body rotates in the opening direction, the finger pinch prevention part rotates so as to enter inside the joining part (inside the vertical frame). There is a concern that a relatively small object may come into contact between the rotating finger pinch prevention part and the connecting part.

A relief recess that opens on the opening side and continues in the vertical direction is provided between the door bottom side frame material, and the dimension of the relief recess in the width direction of the door body is equal to the door bottom side end of the door body. The width of the door body is set to be larger than the width of an object that is expected to be inserted between the door end side frame material, and the door body is arranged to sandwich the door end side aggregate in the door thickness direction. The door end side aggregate has a front side piece that receives the face plate on the open side from the inside thereof, a back side piece that receives the face plate on the non-open side from the inside thereof, and these front side pieces. It has a door end side piece that extends between the end parts of the back side piece on the door end side, and the door end side piece has a stepped cross section having a stepped part recessed toward the door end on the open side in the door thickness direction. The surface plate on the open side has a stepped portion as the relief recess along the step of the door end side piece at the end thereof on the door end side, and A door device characterized in that a dimension in the door thickness direction is larger than a dimension of the relief recess in the door body width direction .

Since the present invention is configured as described above, it is possible to prevent objects etc. from being caught between the door body and the vertical frame.

An airtight member 25 is fitted and fixed in the fitting recess 24b. This airtight member 25 is formed in a long shape that continues in the vertical direction, and is pressed against the door end side portion of the surface plate 16 of the door body 10 when fully closed, and is elastically deformed.

In the door device A having the above-mentioned configuration, a relief recess X is provided between the door end side end of the door body 10 and the door end side frame member 24, and the opening side is open and the relief recess X is continuous in the vertical direction. .
The dimension w of the relief recess X in the width direction of the door body is determined by an object (for example, a fingertip, the tip of an umbrella, etc.) that is expected to enter between the door end side end of the door body 10 and the door end side frame member 24. is set larger than the width dimension. According to the illustrated example, the dimension w is set within a range of 10 to 30 mm.

Further, a plurality of hinges 30 (two in the illustrated example) are provided at intervals in the vertical direction, and are configured to rotate the door end side end of the door body 10 with respect to the door end side frame member 24. Connected.
Each hinge 30 rotates one piece 32 relative to the other piece 33 about a support shaft 31, and is called a hinge or the like.
This hinge 30 fixes the other piece 33 to the door end side frame material 24, and also connects the one piece 32 to the door end side end of the door body 10 on the inner side of the door thickness than the relief recess X (step 14c1). It is attached to the part.

Next, the characteristic functions and effects of the door device A having the above configuration will be explained in detail.
As shown in FIGS. 3(a) to 3(c), as the door body 10 in the fully open state moves to close, the door tail end of the door body 10 and the door tail side frame material 24 of the frame 20 (details) The gap with the opposing piece 24a) gradually narrows.
In the fully closed state of the door body 10 with the minimum gap, an escape recess X having a width of dimension w is secured between the door end side end of the door body 10 and the door end side frame member 24.
This relief recess X is continuous in a long shape over the entire length of the door body 10 in the vertical direction.

During the closing operation of the door body 10, if the above-mentioned object enters between the door end side end of the door body 10 and the door end side frame member 24 from the opening direction side, this object will completely close the door body 10. At this point, it is located within the relief recess X.
Therefore, it is possible to prevent the object from being caught between the door end side end portion of the door body 10 and the door end side frame member 24.

In addition, as shown in FIG. 6(a), an elastic member 61 (for example, a hollow rubber or sponge-like member) that is depressed when pressed by the object may be provided in the relief recess X. good.
According to this aspect, it is possible to effectively prevent the object from entering the escape recess X by the elastic member 61.

<Second embodiment>
Next, other embodiments according to the present invention will be described. In addition, since the embodiment shown below is a modification of a part of the above-mentioned door device A, the modified part will be mainly described in detail, and parts that operate in the same way will be given the same reference numerals and detailed explanations will not be repeated. omitted.
