Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance door, an access door,
The present invention relates to an opening / closing door closing alarm device that emits an alarm when an opening / closing door such as a bathroom door is closed so as not to pinch a finger.

[0002]

2. Description of the Related Art Conventionally, there has been known an entrance sliding door which is provided with a bell, a bell or the like attached to the sliding door so as to make a sound when operating the sliding door to notify the entrance of a person. No one has attached a bell or the like, and there has been no known one that emits a sound only when the door is closed and issues an alarm so that the finger is not jammed.

[0003]

Since there is no prior art door which emits an alarm when it is closed, a finger may be inadvertently caught in the door stop of the door. In addition to the door stop part, the hanging part has a gap between the opening frame and the vertical frame of the door when it is opened, and it is easy to pinch a finger when it is closed. In many cases, inadvertently pinching a finger has been a problem. Therefore, the present invention solves the conventional problems, so that the door stop portion and the hanging portion of the door do not pinch a finger at the time of closing, an alarm is issued at the time of closing to alert the user, and a warning is given for the opening and closing door. The purpose is to provide.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a door that opens and closes the other end with one end of the door as a rotation axis.
Install an alarm transmitter with a bell, a light bulb, etc., and attach one end of an operation cord such as a windable and rewindable string, wire, chain, etc. to the appropriate position of the upper frame of the door body, and attach the other end to the alarm transmitter An opening / closing door closing alarm device that is connected to an operation unit and issues an alarm when the door is closed is configured.

Embodiments of the present invention will be described below with reference to embodiments shown in the drawings. FIG. 1 shows the state of attachment of the closure alarm device of the present invention, and FIG. 2 shows the state of the operation cord when the door body is opened. When the door is closed, the closing alarm device of the present invention provides a connection between the door stop 5 of the vertical frame 2 of the door body 1 and the vertical frame 8 of the opening frame on the door stop side, and the door on the hanging side. In order not to pinch a finger in the space created between the hanging portion 6 of the vertical frame 3 of the main body 1 and the vertical frame 9 of the opening frame,
A warning is given by sound or light to call attention. In the embodiment shown in FIG. 1, the alarm transmitter 13 has a built-in music box. The mounting plate 12 is provided so as to protrude from the upper frame 10 of the opening frame toward the room side, and the alarm transmitter 13 is suspended therefrom. It was attached. Alarm transmitter 1
An operation cord 14 for operating the door 3 is mounted at the same height as the alarm transmitter 13 on the upper frame 4 of the door main body 1, and is automatically wound into the alarm transmitter 13 as the door main body 1 is opened and closed. The operation cord 14 is always rewinded so that the operation string 14 does not slack. Note that the operation cord 14 may be wound up and rewinded by the spring or the like at the attachment portion 7 of the door body 1. FIG. 2 shows a state in which the door main body 1 is opened by a dotted line. The door main body 1 is rotated around the hinge 11 as a rotation axis to move to the outside of the room and the opening is opened. The movement of the door body 1 is pulled out from the alarm transmitter 13, and at the same time, the winding shaft of the operation cord 14 rotates in the reverse direction, thereby winding up the spring of the music box. When the door 1 is closed, the winding shaft of the operation cord 14 rotates forward and the mainspring unwinds and emits a sound as the operation cord 14 is wound, and a finger is pinched between the door stop portion 5 and the suspension portion 6. Call attention. Note that a light bulb may be attached to the alarm transmitter 13 instead of the music box, and the light may be turned on when the door body 1 is closed to provide an alarm by light. In addition, a music box and a light bulb can be provided side by side to generate an alarm by sound and light. The alarm transmitter 13 is attached to the upper frame 4 of the opening frame instead of being attached to the upper frame 10 of the opening frame. The operation cord 14 may be operated by attaching to the control cord 10. Note that the music box built in the alarm transmitter 13 is not special, but a commercially available one can be used, and a bell or the like may be sounded. The example in which the closing alarm device of the present invention is attached to the single-door as shown in FIGS. 1 and 2 has been described above.
It can be used in the case of double doors as well.In addition to the entrance door, it can be attached to the open door of the entrance door, bathroom door, and the door body can be attached to the molded glass door, mold door, flash door, etc. Is also possible.

[0006]

The present invention is constructed as described above, and an alarm transmitter such as a music box, a bell, a light bulb or the like is installed on the upper frame of the opening frame, and is mounted at an appropriate position of the upper frame of the door body that opens and closes. An alarm is issued when the door is closed by operating with a rewindable and rewindable string, wire, chain, etc., so that inadvertent pinching of the finger at the door stop and hanging part of the door is prevented. It is very effective especially for elderly people and children. The closure warning device has a simple structure and can be easily attached to the upper part of the door, and can be retrofitted to the already installed door.
