Description

Door Locks {FIXING DEVICE FOR DOOR}

The present invention relates to a door fixing device for keeping the door fixed in an open state, and more particularly, it is automatically returned when the door is held in the opening direction by the door fixing device to automatically close the door. It relates to a door lock that can be.

Generally, but not exclusively, the front doors of apartments or offices are open. In order to frequently enter or exit the door through the door, or to fix the door open for a long time, a temporary fixing means made of wood or newspaper has been inserted between the bottom and the bottom of the door. However, such a method is temporary and inconvenient to use, and also the door may be closed unexpectedly because the door cannot be kept accurately and stably in an open state, thereby causing a problem that an injured person is 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. This door fixing device, as shown in Figure 1, for example, the mounting piece (1) is fixed by a fixing means such as a bolt in the lower portion of the door (D), the opening and closing device is installed by hydraulic or pneumatic at the top and And a support 3 which is forcibly fixed to the mounting piece 1 by the connecting piece 2. 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 of the support (3) is provided with a stopper (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 held in an open state, the user rotates the support 3 downward by hand while the door D is opened, so that the stopper 4 comes into contact with the floor. The door can be kept open by rotating the support 3 downward by using the foot or by fixing the stopper 4 in contact with the floor. On the contrary, when the door is closed, the door can be freely closed by rotating the support 3 upward by hand or by rotating the support 3 upward by using the foot.

However, such a conventional door fixing device has been shown to have some problems. First, when the user rotates the support upward by hand to release the fixing device by closing the door by opening the door again, it may be unsanitary and injured, and the foot may be damaged. As a result, there is an inconvenience in that the user must directly use his or her hands or feet.

In addition, when the contact between the mounting piece and the support is relaxed or the fixing force of the connecting pin is loosened in the long term or frequent use of the door fixing device, the support is loosened and rotates downward arbitrarily, which may cause trouble or inconvenience in opening and closing the door. There is this.

In addition, even when trying to keep the door fixed in the open state for a long time, there is a problem that the door is randomly closed by the release of the fixing device by children or other external force.

The present invention has been made to solve the above problems, the object of the present invention is to provide a door fixing device that can be released automatically when the door is closed when the door is fixed in the open state again To provide.

Another object of the present invention is to provide a door fixing device that can be rotated upwards automatically when the door is closed in the open fixed state of the door.

Another object of the present invention is to provide a door fixing device that can be prevented from being rotated downward in the non-open fixed state of the door, the support is always rotated upward when not in use.

Still another object of the present invention is to provide a door fixing device that can prevent the door from being closed by any external force.

These objects are installed in a door having an opening and closing device for applying a door closing force to automatically close the upper part, and the door fixing device for keeping the door fixed in an open state. A mounting piece having holes formed to face each other; A support having a through hole communicating with two mounting holes of the mounting piece at one end thereof and having a stopper contactably fixed to the bottom surface at the other end thereof; A connection piece inserted into a communication hole formed by a mounting hole drilled in the mounting piece and a through hole formed in the support to fix the support to the mounting piece in a rotatable manner; And an elasticity which is inserted into the communication hole and at least one end of both ends is selectively contacted and fixed to the mounting piece and the support to push the door in the open direction to apply an elastic force to the support to force rotation in the door release direction when the door is kept open. It can be achieved by a door lock characterized in that it comprises a piece.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring first to Figures 2 and 3, the door fixing device according to the present invention is basically provided with the components as described above. That is, the door fixing device, for example, the mounting piece 10 is fixed to the lower part of the door is installed in the upper part of the automatic closing of the door and installed by the opening or closing device operated by hydraulic or pneumatic, such as bolts (B) It is provided. In the mounting piece 10, two mounting holes 12 are drilled so as to face each other so that a support to be described later may be rotatably fixed.

The mounting piece 10 is rotatably coupled to the support 20 for actually supporting the door. The through hole 22 communicating with each of the installation holes 12 provided in the above-described mounting piece 10 is formed in the upper end or one end of the support 20. In addition, the lower end or the other end of the support 20 is provided with a stopper 24 fixed to the bottom when the door is kept open. Of course, the stopper 24 is preferably formed of rubber or synthetic resin having some elasticity for stable and smooth contact with the bottom. Optionally, a fixing hole 26 may be formed at an appropriate position of the support 20 so that the ends of the elastic pieces described later in detail are elastically fixed.

On the other hand, the support 20 is connected to each other by the connecting piece 30 to be rotatable up and down with respect to the mounting piece (10). The connection piece 30 is formed to be inserted into a communication hole formed by each of the installation holes 12 formed in the mounting piece 10 and the through hole 22 formed at the end of the support 20.

In particular, the door fixing device according to the present invention further includes an elastic piece 40 for automatically rotating the support upwards. The elastic piece 40 may be formed of an elastic wire or an elastic spring. For example, one end portion 42 of the elastic piece 40 is supported or fixed to the mounting piece 10, the other end 44 is supported or fixed to the support 10 to the elastic force or in a direction opposite to each other It is preferable to be installed so that a pressing force is applied. In this way, the elastic piece 40 is applied to the mounting piece 10 and the support 20 in the direction opposite to each other, so the support 20 is always upward with respect to the mounting piece 10 fixed to the door. It can be rotated.

On the other hand, the elastic force or expansion force of the elastic piece 40 is preferably set smaller than the hydraulic or pneumatic pressure of the opening and closing device of the door (not shown). That is, the elastic force of the elastic piece 40 should be formed to be smaller than the pressure set so that the door opening and closing device (not shown) installed above the door D is applied to the door to automatically close the door. As will be described later in detail, in order to keep the door open, the support 20 of the door fixing device is rotated downward to support the support 20 arbitrarily rotated upward to close the unwanted door. This is to prevent from happening.

Meanwhile, as shown in FIG. 5, according to another embodiment of the present invention, in order to prevent the fixing device from being released by external force when the door is kept open for a long time, that is, the support is in the original position. Locking device (50) may be further provided to prevent the return to. In order to further install the locking device 50, the mounting piece 10 and the support 20 must be formed with a hole for the lock. That is, the insertion hole 14 is formed in one side or both sides of the support 10a of the mounting piece 10, the upper portion of the support 20 is a chain hole to communicate with the insertion hole 14 when the door is fixed (28) is to be formed. At this time, the locking device 50 is a body 52 penetrating through the lock hole 28 so as not to be separated from the insertion hole 14, and integrally formed in the body and protrudes to the outside to be gripped by the user by hand It can be formed as a head 54 that can be released.

Optionally, the head 54 of the locking device 50 may be connected to the door or the mounting piece 10 by a connecting line 56 to prevent loss of the locking device 50.

Hereinafter, the installation and operation of the door fixing apparatus according to the present invention configured as described above will be described in detail with reference to FIGS. 4 and 2 and 3.

First, the worker mounts the mounting piece 10 at the lower position of the door D by using the bolt B, thereby completing the installation of the door fixing device for the door.

As such, in the state in which the door fixing device is installed in the door or the door is closed, the support 20 of the door fixing device is rotated upward by the elastic piece 40 to maintain the free opening and closing of the door. Done. That is, one end portion 42 of the elastic piece 40 is supported by the mounting piece 10 so as to be releasable and the other end portion 44 is fixed to the support 20, so that the elastic force or the pressing force applied to the support 20 is increased. It is applied to maintain the support 20 is rotated upwards, and finally, as shown by the dotted line in Figure 4 the support 20 is rotated upwards to maintain the state in contact with the door (D). . Accordingly, the door can be opened and closed smoothly without being blocked by the door fixing device.

In such a state, in order to fix the door in the normally open state while the user opens the door D to the direction of the arrow A1, the support 20 is rotated in the direction of the arrow A2 using the foot to its end portion. After fixing the stopper 24 provided in contact with the floor to release the door (D) in a free state. At this time, the door (D) is the door closing force of the door opening and closing device (not shown), that is, the closing force (F1) of the door is greater than the set elastic force (F2) of the elastic piece 40, so that the support 20 is supported By being forced, the door D is fixed and supported in an open state.

Then, if the user wants to close the door (D) by further opening the door (D) in the direction of the arrow (A3), the closing force (F1) of the door (D) by the door opening and closing device is released to the elastic piece 40 The support 20 is rotated upwards in the direction of the arrow A4 by the elastic force F2 of).

In this way, the support 20 is rotated upward, so that the fixed or supported state of the door D is automatically released, thereby allowing the door to be closed or opened freely.

On the other hand, as shown in Figure 5, if further provided with a locking device 50, it is possible to prevent the door to be closed arbitrarily, for example, the fixing device is released by a child or another person. That is, in order to secure the door D in an open state for a long time, in a state in which the support 20 is rotated downward to support the door D, the user grips the head 54 of the locking device 50 and The body is inserted into the insertion hole 14 and the chain hole (28) to communicate with each other. When the support 20 is integrally fixed to the mounting piece 10 by the locking device 50, the door is not closed even if the door D is slightly opened in the opening direction by external force. Of course, in order to close the door, the user pulls out the locking device 50 and then slightly opens the door in the opening direction. As described above, the support 20 automatically rotates upward to close the door.

Accordingly, when the door is to be closed by the door fixing device to maintain the fixed state, the user may open the door slightly in the opening direction without directly releasing the support by using a foot or hand separately. By automatically releasing the door by the support, the user can conveniently close the door.

As a result, according to the door fixing device according to the present invention, when the door is closed by being opened and fixed by the door fixing device, if only the door is slightly opened in the opening direction, the support is automatically moved upward by the elastic piece. Since the door is rotated to be released freely to close or open the door, the user's convenience is improved.

In addition, since the user does not need to directly release the fixing device by using the hand or the foot, there is an advantage in that the safety of the user is improved.

In addition, in the non-opening state of the door by the elastic piece is prevented from being rotated downward arbitrarily, there is an advantage that the reliability is improved because it does not interfere with the opening and closing of the door.

In addition, since the fixing device is released by a child or the like to prevent the door from being closed, safety under the reliability is further improved.

Although a preferred embodiment according to the present invention has been described above, it will be understood by those skilled in the art that various modifications and variations can be made without departing from the scope of the appended claims.
