Description

Door holder {Door holder}

The present invention relates to a door fixing device, and more particularly, to a door fixing device that keeps a door open and prevents it from being closed unintentionally.

A door is a generic term that functions to open or close a space and space as needed. Automatic doors and revolving doors are also included in the broad sense of the door, but usually the user turns the handle to unlock the door or open or close it. refers to closing.

In particular, it is common to open such a door in a home, and when a separate hydraulic hinge is not provided, the user tends to keep the door open.

However, the door opened in this way is particularly affected by the air introduced from the outside or is momentarily opened or closed due to the user's carelessness.

When the door is momentarily opened or closed unintentionally, a user's surprise or injury is highly likely to occur.

In order to prevent such unintentional opening or closing of the door, various technologies have been proposed. In general, the following prior art and similar products that are fixed to the door as a 'horseshoe' are released, but in this case, only the closing is prevented. However, there is a problem that it cannot be prevented from opening, and furthermore, the process of folding or unfolding the horseshoe is cumbersome.

Hereinafter, the door fixing device of the present invention will be described in detail with reference to the accompanying FIGS.

1 and 2 , the door fixing device according to the present invention rotates at a certain angle according to the advance of the body 100 fixed to the floor, the push button 200 moving forward and retreating from the upper part, and the push button 200 moving forward. It is made of including a rotating body 300, and a door piece 500 that is fixed to the door to advance the push button 200.

First, the door is provided with a door piece 500 protruding downward while maintaining a predetermined distance from the door in the direction in which the door is opened. Such a door operates the door fixing device of the present invention as the door is opened, maintains the fixed state of the door, and re-operates the fixing device to release the door again. A detailed embodiment of such a door piece 500 will be described later.

The body 100 is positioned where the user wants to maintain the desired open state while the door is opened, and is easily attached to the floor using fixing means such as adhesives or screws. In a more detailed configuration according to this embodiment, the upper body 110 and the lower body 130 are formed so as not to leave the push button 200 and the rotating body 300 in the middle, as an example in the drawing, two coupling parts 140 ) through a force fit or a piece connection.

The upper body 110 is provided with a U-shaped groove 120, so that the push button 200 can be moved forward and backward along the groove while protruding upward.

The push button 200 has a shape in which the button body 220 protrudes from the upper part of the flat moving plate 210 , and the moving plate 210 is in close contact with the upper body 110 so that the push button 200 is stably moved forward and backward. let it do And according to the present embodiment, the support plate 230 protrudes from the lower portion of the moving plate 210 and comes in close contact with the lower body 130, thereby enabling more stable forward and backward movement.

The moving plate 210 of the push button 200 has a relatively small size or a larger size positioned between the coupling parts 140 as shown in the drawing and a slide groove (not shown) through which the coupling part 140 passes. Despite the configuration of the coupling part 140 while providing, the push button 200 is not affected by forward and backward movement.

The button body 220 is integrally formed on the upper part of the moving plate 210 and protrudes through the C-shaped groove 120 of the upper body 110, so that when the door piece 500 of the door touches, it advances and elastically retreats. will do In particular, in order to absorb the impact with the door piece 500, it is preferable to be made of a material such as rubber or silicone, or to be coated or provided with a separate shock absorption means.

In this way, the push button 200 elastically moves forward and retreats by providing an elastic spring supported from the upper body 110 on the rear side of the moving plate 210 .

The rotating body 300 is integrally formed with the intermittent ring 320 having the concave-convex 330 toward the top on the outer diameter of the rotating plate 310 . In particular, the rotating plate 310 rotates while being interposed between the lower body 130 and the upper body 110 as shown in FIG. Located.

At this time, when the lower body 130 is circular, a circular groove 340 in which the lower body 130 is seated is formed in the lower portion of the rotating plate 310 , so that the rotational position does not deviate and stable rotation is possible. Furthermore, when the upper body 110 is circular, the inner diameter of the intermittent ring 320 from which the irregularities 330 protrude corresponds to the circular shape of the upper body 110, so that the rotational position does not deviate and stable rotation is possible.

Of course, it is of course possible to selectively install a bearing between the lower body 130 and the rotating body 300 and the upper body 110 for smoother rotation.

Intermittent ring 320 is concave upwards or irregularities (凹凸: 330) are repeatedly formed so that the concave portion is located in the U-shaped groove 120 of the upper body 110 or the convex portion is located therein according to the rotation. Therefore, when the concave portion is located in the C-shaped groove 120, the door piece 500 of the door can pass through the C-shaped groove 120 and the outside without any influence, but the convex portion is the C-shaped groove 120 ), the movement is restricted. (In this way, the concave or convex portion of the C-shaped groove 120 is positioned so that the door piece 500 passes is referred to as a 'door piece entrance'. Hereinafter, the same)

That is, when the door is opened and the convex portion is located at the door piece entrance while the door piece 500 enters into the intermittent ring 320, the door piece 500 cannot go out, and as a result, the door remains open. .

However, the convex portion of the intermittent ring 320 may have an inclination 360 formed toward the outside, and in this case, the door piece 500 is inclined 360 ) to be able to enter into the intermittent ring 320 over the ride.

In the end, in the process of the door opening, when the concave portion of the intermittent ring 320 is located at the entrance of the door, as well as when the convex portion is located, the door piece 500 passes over the slope 360 and enters the intermittent ring 320. By being able to perform a stable function of the door fixing device of the present invention.

On the other hand, it is preferable that the door piece 500 of the door can elastically move up and down so as to easily pass the inclined surface of the intermittent ring as described above.

For this purpose, it is preferable to prevent the door piece 500 from being damaged from possible impact by forming a configuration in which the door piece 500 protrudes from the housing having a built-in spring on the side where the door is opened.

The door piece 500 enters the inside of the intermittent ring in the process of opening the door and impacts the button body 220 of the push button 200 to advance the push button 200 in the door opening direction. In this process, like the button body 220, it is preferable that it is made of a material such as rubber or silicone or coated with it in order to absorb the impact.

Meanwhile, in the door fixing device of the present invention, as the push button 200 advances, the rotating body 300 rotates a certain angle, which is achieved by a rotator configuration.

The rotator is achieved by the interaction of the pawl 240 provided in the push button 200 and the ratchet 350 provided in the rotating body 300, and with reference to FIGS. 4 to 6 additionally It will be described in detail.

The rotating plate 310 of the rotating body 300 is cut inside to form a ratchet 350 which is a sawtooth having directionality. And the coupling part 140 connecting the upper body and the lower body 130 passes through the inside of the space cut in this way, and furthermore, the support plate 230 protruding from the lower part of the push button 200 is the lower body 130 . comes in direct contact with

Meanwhile, at a height corresponding to the rotation plate 310 in the push button 200 , a ratchet 350 protrudes in the lateral direction. In more detail, when the pawl 240 protrudes in the direction from the support plate 230 protruding to the lower portion of the push button 200 , it accurately corresponds to the ratchet height of the rotation plate 310 .

The pawl 240 is normally engaged with the ratchet 350 teeth to suppress the reverse rotation of the rotating plate 310 . And when the push button 200 moves forward, the pawl 240 pushes up the ratchet 350 to rotate the rotating body 300 at a predetermined angle. And when the push button 200 is sufficiently advanced, it is elastically retracted again and meshes with the next gear tooth of the ratchet 350 .

Eventually, when the push button 200 is advanced by the door piece 500 , the pawl 240 rotates the ratchet 350 at a predetermined angle, thereby rotating the rotating plate 310 by a predetermined angle, and the angle is the intermittent ring 320 . The unevenness 330 coincides with the continuously formed angle. Therefore, when the push button 200 is pressed once, the concave portion and the convex portion of the intermittent ring 320 and the concave-convex portion 330 are sequentially positioned in the C-shaped groove 120 .

Meanwhile, an additional stopper 150 may be provided in order to prevent the possibility that the pole 240 is retracted and the rotating plate 310 partially reversely rotates during the operation of the rotator. If the pawl 240 retracts and rubs against the ratchet 350 of the rotating plate 30 to rotate it in reverse, the pawl does not mesh with the next gear, so the rotating plate 310 reliably places the unevenness 330 at the door entrance. Alternate positions cannot be expected.

In order to prevent this, for example, a leaf spring provided downward from the lower portion of the upper body 110 is provided and is engaged with the ratchet 350 rotated at a predetermined angle by the pawl 240 so that the pawl 240 returns to its original position. While doing so, the reverse rotation of the rotating plate 310 is prevented.

The door fixing device according to the present invention can be attached to the floor with an adhesive or double-sided tape on the lower portion of the lower body 130 or firmly attached to the floor with screws or the like. However, in order to be fixed to the floor in this way, it may be difficult to damage or remove the floor because it must be fixed fairly firmly for reliable operation.

In order to prevent this problem, the door fixing device of the present invention further includes a bridge 400 for fixing to the wall rather than the floor as shown in FIGS. 7 and 8 .

One end of the bridge 400 is fixed to the upper portion of the upper body 110 and the other end is fixed to the wall beyond the rotating plate 310 . Since the door fixing device generally maintains the door in a wide open state, the widely opened state is positioned close to the wall.

At this time, the other end of the bridge 400 is attached to the bottom of the wall with an adhesive or double-sided tape, the adhesive strength may be relatively weak. In other words, since it is possible only with an adhesive force that prevents lateral movement, damage to the wall is relatively small.

This is because the door fixing device of the present invention is locked by advancing in the wall direction and the unlocking process is also made in the wall direction, so that the wall itself absorbs the impact and does not depend on a large adhesive force.

Then, the usage of the door fixing device of the present invention as described above will be described in detail with reference to FIGS. 9 to 12 .

The door fixing device of the present invention is fixed where the door piece 500 is located in a state in which the user wants to keep the open state on the path where the door is opened. At this time, the initial position of the concave-convex 330 of the rotating plate 310 is such that a concave portion is located at the entrance of the door. When the user opens the door, the door piece 500 enters the door piece entrance and immediately collides with the button body 220 with inertia to advance the push button 200 (FIG. 9).

Then, the rotating body 300 is rotated by a predetermined angle by the rotator, and a convex portion is positioned at the entrance of the door. This state is an open and fixed state, and the door piece 500 is blocked by the convex portion of the intermittent ring 320 so that the movement is restricted and the open state is maintained ( FIG. 10 ).

In order for the user to release the locking state of the door and close the door, the user only has to slightly push the door in the direction of opening again. Then, the door piece 500 placed between the intermittent ring 320 and the push button 200 is Advance further (FIG. 11). Then, the rotating body 300 is rotated by a certain angle once again by the rotator, and a concave portion is located at the door piece entrance, and the user can remove the door piece 500 from the intermittent ring 320 and close the door ( 12).

On the other hand, the present invention is basically used when the recessed portion of the intermittent ring 320 of the door piece 500 is located at the door piece entrance as shown in FIG. 13, but due to some malfunction, the door is opened and fixed as shown in FIG. In the process, a situation in which a convex part is placed at the entrance of the door may occur. In this case, the door piece 500 rides on the slope 360 formed in the convex portion of the intermittent ring 320 and elastically crosses the intermittent ring 320, thereby achieving a fixed state of the door, and the function of the present invention is is continuously implemented.

As a result, the user can comfortably maintain or release the door fixing state even if the user holds the door itself and repeats the opening process without much force without having to turn or operate the door fixing device of the present invention in any situation. be able to perform
