Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door closing prevention device that is used, for example, when cleaning a room, and holds a door slightly open.

[Conventional technology]

For example, when cleaning a room in a hotel or the like, or when carrying out various construction work inside or outside the room, it is necessary to frequently enter and leave the room.

In such cases, especially in the case of an automatic locking type door, a key must be used each time the door is opened or closed, and even if the door is not an automatic locking type, the knob must be turned each time, which is inconvenient. Therefore, in such a case, the work can be carried out smoothly by keeping the door fully open or half open.

However, if the door is kept fully open or partially open, for example, if the door is left open on the hallway side of a hotel, etc., it will be a nuisance to passersby in the hallway, and the inside of the room will be exposed, making it difficult to maintain privacy. This will cause problems.

Therefore, in reality, the door is held in a very slightly open state by inserting a piece of wood or the like between the joint between the hand end of the door opposite the hanging base and the doorway frame. According to this, the door does not obstruct passersby, and it also protects the privacy of the room.Furthermore, when entering and exiting, there is no need to use a key or turn a knob. You can easily open the door and enter or exit by pushing or pulling the door with your body or body.

[The problem that the idea aims to solve]

However, the method of inserting a piece of wood or the like into the door as described above has disadvantages such as making a banging sound every time the door is closed, being easily damaged, and being easily lost.

The object of the present invention is to solve such problems and provide a door closing prevention device that can be attached to and removed from the door with a single touch without damaging the door or emitting noise.

[Means for Solving the Problems] In order to achieve the above object, the door closing prevention device of the present invention targets a door 2 having inner and outer knobs 3a and 3b, and is made of elastic material such as rubber or soft plastic. Band-shaped preventer body 1 made of plastic material
is formed with a knob locking part 5 having a knob through hole 4 which can be freely inserted into and removed from the knobs 3a and 3b at both ends in the longitudinal direction of the band, and a knob locking part 5 is formed between the knob locking parts 5 and 5 on the hand side of the door 2. A spacer portion 6 is formed to fit on the end 2a.

It is preferable that a through hole 8 be provided in the spacer portion 6 .

[Effect]

The door closing prevention device having the above structure is constructed by applying the spacer portion 6 to the hand side end 2a of the door 2, and bending the connecting portions of the spacer portion 6 with the knob locking portions 5 at both ends to connect the knob 3a on the indoor side and the indoor side. By hooking each outer knob 3b through the knob through hole 4,
Can be attached to door 2.

Door 2 with a door closure prevention device installed like this
Even when this is closed, the preventer main body 1 is sandwiched between the joint with the entrance/exit frame 7, and the preventer body 1 is held in a slightly open state.

[Effect of idea]

The door closing prevention device of the present invention uses the inner and outer knobs 3a and 3b of the door 2 to allow the knob through hole 4 of the knob locking part 5 to be inserted and removed, so that the door 2 can be opened by simply inserting and removing it. Easy to install,
Can be removed. In addition, there is no fear that the door closing preventive devices hung on the inner and outer knobs 3a and 3b will accidentally separate or fall off from the door 2 when the door 2 is opened or closed.

In addition, since this door closing prevention device is entirely made of elastic plastic material such as rubber, it is not only easy to bend to accommodate slight differences in the thickness of the door 2, but also easy to bend when closing the door 2. Doorway frame 7
Since it exerts a buffering effect on the air, it can be closed silently without making any noise, and the door 2 will not be damaged.

Furthermore, when the door closing prevention device is not in use, it can be expanded into a band shape, making it less bulky, making it convenient for workers to carry.
In addition, the shape and structure are simple, and the molding process can be performed easily and inexpensively. Furthermore, “HOUSE-KEEPING”
It is also convenient because it can also be used as a display board to display information such as "Cleaning work in progress" or "Cleaning work in progress".

〔Example〕

A first embodiment of the door closing prevention device according to the present invention is shown below.
This will be explained based on the diagram and FIG. The main body 1 of this preventer is made of a highly elastic plastic material such as rubber, synthetic rubber, or soft plastic, and is formed into a strip shape, and the longitudinal ends of the strip have circular or square shapes that can be passed through the inner and outer knobs 3 of the door 2. An annular knob locking portion 5 having a knob through hole 4 such as the knob locking portion 5, etc. is formed.
5 is the end 2 on the hand side opposite to the hanging source of the door 2
It is shaped in such a way that it is connected to the doorway frame 7 by a spacer part 6 which is placed between it and the doorway frame 7. The thickness of the spacer portion 6 is set to such an extent that a slight gap is created between the joint between the hand end 2a of the door 2 and the doorway frame 7 when the door is opened. Further, by opening a square, circular, etc. through hole 8 in the spacer portion 6, even if the spacer portion is thick, it is made easier to bend. Note that characters 12 such as "HOUSE-KEEPING" and "Cleaning in progress" are displayed on the surface of the preventer main body 1 at the connecting part between the knob locking part 5 and the spacer part 6.

When this is used, the spacer part 6 is attached to the door 2.
By folding the preventer main body 1 in half into the outside and outside of the door 2 and hooking it through the knob through hole 4 of the knob locking part 5 to the inside and outside knobs 3a and 3b, respectively, the door can be opened. The closing preventive device is attached to the constriction at the base of the knob 3 so as to prevent it from coming off, and to sandwich the hand end 2a of the door 2.

When the door closing prevention device is installed in this way, even when the door 2 is closed, the spacer portion 6 of the prevention device main body 1 will be caught between the joint between the hand side end 2a of the door 2 and the doorway frame 7, so that the door closes. 2 is not completely closed, but is kept open with a slight gap between it and the doorway frame 7.

By keeping the door 2 slightly open, privacy inside the room can be protected during cleaning or construction work, and even if the door is an automatic locking type, there is no need to use a key. The door 2 can be easily opened by simply pushing or pulling the door 2 without turning, and the work can proceed smoothly. Also, when the door 2 is closed, the buffer is relaxed by the preventer main body 1, so there is no closing sound and no damage is caused to the door 2.

After the work is completed, the door closing prevention tool can be easily removed from the door 2 by pulling out the knob through hole 4 of the knob locking part 5 from the knob 3.

[Another example]

Since the door closing prevention device of the above embodiment has the through hole 8 in the spacer portion 6, it can not only escape from the latch 10 and dead bolt 11 of the lock 9 of the door 2, but also becomes easier to bend, and also saves material and weight. However, the through hole 8 is not necessarily necessary.

Further, although it is most advantageous to apply the present invention to the swinging door 2, it is equally applicable to the sliding door.

Furthermore, it goes without saying that the knob 3 of the door 2 may be of a lever handle type other than that shown.
