Description

Door opening state maintaining device {Holding device for door}

The present invention relates to a door open state maintaining apparatus, and more particularly, to a door open state maintaining apparatus that allows the user to maintain the open state of the door by operating the handle up and down using the hand in the standing state.

In general, doors in apartments or offices are installed in a swinging manner. In order to frequently enter or leave the door open for a long time, a temporary fixture made of wood or newspaper has been inserted between the bottom and the bottom of the door.

However, this method is temporary and inconvenient to use, and also the door may be closed unexpectedly because the door may not be kept accurate and stable in the open state, thereby causing a problem that an injured person may be injured.

On the other hand, in order to solve such a problem in recent years, a door fixing device called a "presser foot" is installed and widely used. As shown in FIG. 1, this door fixing device is pivoted to the mounting piece 1 by a mounting piece 1 fixed to the lower part of the door D, for example, by a fastener such as a bolt, and a connecting piece 2. It is provided with a support stand 3 which is forcibly fixed.

Of course, the support 3 may be integrally formed with a footrest for the user to rotate the support with the foot. In addition, the end portion of the support (3) is provided with a packing (4) formed of a rubber-like material so that it can be stably in contact with the bottom surface.

According to this configuration, when the door D is to be fixed and maintained in the open state, the user rotates the support 3 downward by hand while the door D is opened so that the packing 4 contacts the floor. Alternatively, the support 3 can be rotated downward by using the foot, and the packing 4 can be kept in the open state by fixing the packing 4 in contact with the floor.

On the contrary, when the door is closed, the door can be freed and closed by rotating the support 3 upward by hand.

However, the door opener is mounted on the lower part of the door, so it is usually operated by foot rather than by human. That is, in order to fix the door in the open state, the support of the door opening fixing device is lowered to the ground by the foot, and the door is opened and the fixed door opening fixing device is lifted using the foot again to return to the original position.

However, the door opening fixing device not only supports the door diagonally at the bottom of the door, but the supporting means of the door opening fixing device has a short length, so that it is not easy to return the door opening fixing device to its original position using the foot.

In addition, to lower the support down and then up again after using it, a constant force must be given and the door fixing device must be folded to the top until the end.

In addition, such a conventional door fixing device appeared to have some problems. First, when the user rotates the support upward by hand in order to close the door by releasing the fixing device again with the door open, there is an unsanitary and inconvenient need to bend the waist. Not only could it be damaged, but it could not be controlled precisely, resulting in the inconvenience of having to repeat several times.

In addition, when the door fixing device is used for a long time or frequently, the contact between the mounting piece and the support is relaxed or the fixing force of the connecting pin is relaxed, causing the support to be arbitrarily rotated downward, thereby causing trouble or inconvenience in opening and closing the door. There is this.

Therefore, there was often the hassle of having to bend over and lift the door open lock by hand.

Therefore, an object of the present invention is to allow the user to easily achieve the open state and the locked state of the door only by the handle lifting and lowering operation using the hand in the standing state.

In order to achieve the above object, the door open state maintaining device of the present invention is mounted on the bottom of the rotatable open door, and in the fixing device for maintaining or releasing the open state of the door, a coupling hole is formed on the outer bottom surface in the rotational direction. And a stopper in communication with the coupling hole, the door having an operation hole formed at the center of the rear surface corresponding to the interior side, and a stopper coupled to the coupling hole of the door so as to be movable up and down, and having a rubber packing having a high coefficient of friction at the bottom thereof. A connection link connected to an upper portion of the stopper and vertically upwardly connected to an inner space of the door, and orthogonally coupled to an upper portion of the connection link to be exposed to the outside through an operation hole to move up and down in the operation hole; It consists of a handle that links the stopper.

According to the present invention, the operation hole is disposed on the side of the handle to determine the locking state in the door, a vertically provided transfer hole is provided, and each engaging hole in the direction perpendicular to the communication hole in the upper and lower portions of the transfer hole Configure it to

According to the present invention, by forming a pair of engaging jaw through which the connecting link is vertically penetrated at the upper part of the coupling hole, the spring is built in the outer periphery of the connecting link located between the upper end of the stopper and the engaging jaw. do.
