Description

The present invention relates to an emergency opening device for a folding door used particularly in a narrow space such as a bathroom or a toilet.

Folding doors used in narrow spaces such as bathrooms and toilets often get in the way when they protrude outside the room, so they usually fold into two while opening into the room.
In this case, if an elderly person or sick person falls into a folding door on the indoor side due to a seizure or sudden illness, or falls close to the folding door, the folding door may be opened to the indoor side. As a result, it was difficult for the elderly and suddenly ill people inside to be rescued.
Therefore, an emergency opening device for a folding door that can open the folding door from the outside has been provided. (For example, refer to Patent Document 1.)

And in the said structure, two doors are attached in the frame which consists of an upper frame and a side frame, the two doors are connected while the side edges of these two doors rotate freely, and this connection part protrudes. In a folding door that opens in a fold, the rotary shaft provided at the upper end of one door is rotatably attached to the upper frame of the frame, and the slider attached to the upper end of the other door is rotatably attached to the frame. It is attached so that it can move in the rail frame provided in the upper frame, and the rail frame near the moving element of the other door when the door is closed is attached so that it can be removed from the outside.
In the event of an emergency, remove the rail frame in the vicinity of the slider so that the slider attached to the door can move outward, rotate the folding door around the rotation axis of one door, I try to open the folding door.

In this case, since the rail frame connected to the upper frame is located at a high place, the work of removing the rail frame is complicated, and a step or the like is required, so that it was not possible to respond quickly in an emergency.
In addition, if a suddenly ill person falls down in a state of being drowned in a door, the weight is loaded in the direction toward the outside of the room, so the folding door is suddenly turned outward at the same time as the rail frame is removed. Therefore, in the state where the rail frame that was lifted up on the platform and further removed was held, it was extremely dangerous because the rotating folding door could not be supported.

Japanese Patent No. 3132906

  An object of the present invention is to provide an emergency opening device for a folding door that can open the folding door in an emergency in a simple operation and safely.

  Therefore, in order to solve the above-mentioned problems, the present invention is configured as a first means in which a first door whose open side end is rotatably supported by a door frame, and a closed side end of the first door A second door whose open side end is foldably connected to the first door, and a guide member provided on the upper end of the second door is guided along a rail member disposed on the door frame, and the first door In the folding door that is opened in a folded manner while the connecting portion of the second door protrudes indoors, the open end of the rail member is pivotally connected to the door frame, and the closed end of the rail member is latched The latch member is detachably held on the door frame via the member, and the latch member releases the locking state of the rail member and the door frame by an operation from the outdoor side, and the rail member is moved to the outdoor side together with the first door and the second door. Can be rotated.

  Next, when the present invention is configured as the second means, the first door whose opening side end portion is rotatably supported by the door frame, and the opening side end portion on the closing side end portion of the first door. A second door that is foldably connected, and a guide member provided at the upper end of the second door are guided along a rail member disposed on the door frame, and the first door and the second door are connected. In the folding door that is opened in a folded manner while the portion projects inward, the open end of the rail member is pivotally connected to the door frame, and the closed end of the rail member is connected to the door frame via the latch member. An operating portion for operating the latch member is provided facing the outdoor side, and the latch member releases the locked state of the rail member and the door frame by the operation from the outdoor side. The member can be turned to the outdoor side together with the first door and the second door.

Next, when the present invention is configured as the third means, in addition to the second means, the operation portion is located below the latch member and is provided with an operation hole that can directly push up the latch member. It is configured.

Then, the present inventors have constructed as a fourth means, in addition to the second means, the operation unit includes a push-up operating member for the push-up operation of the latch member located below the latching member, press It has an operation hole for operating the push-up operation member located below the lift operation member

  According to the first means, the open end of the rail member is pivotally connected to the door frame, and the closed end of the rail member is detachably held by the door frame via the latch member. Therefore, the rail member can be turned to the outdoor side together with the first door and the second door only by releasing the latching state of the rail member and the door frame by operating the latch member from the outdoor side. The opening operation can be performed easily, and it is not necessary to hold unnecessary members during the opening operation in an emergency. It is safe.

  According to the configuration of the second means, the effect of the configuration of the first means can be easily obtained through the operation member.

According to the configuration of the third means, in addition to the effect of the configuration of the second means, only the operation hole capable of directly pushing up the latch member is provided as the operation portion, so the structure is simple. Can be manufactured inexpensively.

According to the configuration of the fourth means, in addition to the effect of the configuration of the second means, the operation unit is configured to operate the push-up operation member and the push-up operation member that push-up the latch member. Since the operation holes are positioned below the operation holes, the operation holes can be provided closer to the person who pushes up the latch member, and the release operation of the latch member is easier.

  The present invention includes a first door having an open side end rotatably supported by a door frame, a second door having an open side end foldably connected to a closed side end of the first door, The guide member provided at the upper end of the two doors is guided along the rail member disposed on the door frame, and the connecting portion of the first door and the second door is folded in two while protruding toward the indoor side. In the open folding door, the open end of the rail member is pivotally connected to the door frame, and the closed end of the rail member is detachably held by the door frame via the latch member, and the latch member is operated. The operation portion for performing the operation includes a push-up operation piece that is positioned below the latch member and operates the latch member, and an operation hole for operating the push-up operation piece that is located below the push-up operation piece.
