As shown, the door holding device 100 of the present embodiment includes a case 120 fixedly installed at the lower end of the door 20 and a horseshoe member 110 installed in the case 120 to be elevated. have. That is, when the horseshoe member 110 installed in the case 120 descends and comes in contact with the bottom surface, the door 20 is not closed by frictional resistance. When the horseshoe member 110 is raised, the resistance is released and the door 20 is released. ) Is closed. In addition, reference numeral 130 denotes a spring that provides an elastic force in the direction in which the horseshoe member 110 rises, and when the horseshoe member 110 is placed without hanging in the lowered state, the spring is immediately raised by the restoring force of the spring 130. Done. Therefore, while the horseshoe member 110 can be held in a lowered state and can not be lifted again, it is necessary to have a locking means that can be easily released by one touch. In this embodiment, the locking jaw 122 formed in the case 120 and , The locking projection 111 provided in the horseshoe member 110 is used as the means. That is, when the locking protrusion 111 of the horseshoe member 110 descends on the guide hole 121 of the case 120 and is caught by the locking jaw 122 (see FIG. 4A), the restoring force of the spring 130 is opposed. As soon as a lock is in place, it stops in place. Therefore, the horseshoe member 110 makes the locking jaw 122 in a position that can support the door 20 does not close, and when the horseshoe member 110 comes down at that position, the locking protrusion 111 is caught and locked. will be. Then, the release of the locking can be done by lightly hitting the area with the locking jaw (122). Then, the horseshoe member 110 is moved backwards within a small gap between the case 120 and the catching protrusion 111 is removed from the catching jaw 122 (see FIG. 4B). And as soon as the engaging projection 111 is removed, the restoring force of the spring 130 acts to raise the horseshoe member 110.

When opening the door 20 using the door support device 100 having such a configuration, first, the engaging protrusion 111 of the horseshoe member 111 protruding through the guide hole 121 of the case 120. Press with your foot to lower. Then, as shown in Figure 4a as the horseshoe member 110 is lowered, the locking projection 111 is caught by the locking jaw 122 at the end of the guide hole 121. This position is the position where the horseshoe member 110 touches the bottom surface, and in this state, even if the foot is released, the locking protrusion 111 is caught in the locking jaw 122 so that the horseshoe member 110 does not rise again. do. Thus, the door 20 is kept open by the frictional resistance of the horseshoe member 110.

And, to close the door 20, as described above, lightly kicks the portion of the locking protrusion 111 hanging on the locking jaw 122 with a foot. Then, as the horseshoe member 110 is pushed back slightly as shown in FIG. 4B, the locking protrusion 111 is removed from the locking jaw 122, and at the same time, the horseshoe member 110 is raised as shown in FIG. 4C by the restoring force of the spring 130. Done. Therefore, since the frictional resistance of the horseshoe member 110 is released, the door 20 is closed.

In summary, when the door 20 is opened, it is possible to step on the locking projections 111 so as to be caught by the locking projections 122, and when the door 20 is closed, a portion of the locking projections 111 may be lightly kicked with a foot. Therefore, the locking and releasing operations for holding and releasing the door 20 are almost one-touch, so that the operation is convenient and the risk of damaging the shoe or the foot disappears.

Next, Figure 5 shows a door brace device 200 according to another embodiment of the present invention.

The door brace device 200 according to the present embodiment also has a case 220 running on the door 20, a horseshoe member 210 installed in the case 220 so as to be elevated, and a spring for raising the horseshoe member 210 ( 230 is provided. Then, in this embodiment, the locking means for holding the horseshoe member 210 in the lowered state uses a structure such as a latch. That is, the guide hole 230 of the case 220 is made in a form in which the vertical path 231 and the horizontal path 232 are connected, and the engaging rod 211 that moves along the guide hole 230 in the horseshoe member 210. ) To lock and release according to the position of the locking rod (211).

How to use the device 200 is as follows.

First, to support the door 20 in the open state, as shown in Figure 6a by stepping on the locking rod 211 by the foot to descend along the vertical path (231) and then pushed toward the horizontal (232). Then, since the locking bar 211 is trapped in the horizontal path 232, it is possible to maintain its position against the force of the spring 230 pulling in the vertical direction. This position is the position where the horseshoe member 210 is in contact with the bottom surface, the door 20 is maintained in the open state by the frictional resistance of the horseshoe member 210.

And, to close the door 20, lightly push the engaging rod 211 toward the vertical path 231 as shown in Figure 6b. Then, the engaging rod 211 is out of the horizontal path 232, and at the same time the horseshoe member 210 is raised as shown in Figure 6c by the restoring force of the spring 230. Therefore, since the frictional resistance of the horseshoe member 210 is released, the door 20 is closed.

Therefore, the device 200 of the present embodiment also has a locking and releasing operation for holding and releasing the door 20, which is performed by almost one-touch operation of pushing the locking rod 211 to the horizontal direction 232 and then removing it. This is convenient and eliminates the risk of damage to shoes or instep.

As described above, the door brace device according to the present invention provides the following effects.

First, the operation of holding and releasing the door is almost one-touch, so the operation is very convenient.

Second, the operation using the foot is enough to step on the operation unit or kick light, safety accidents such as scratching shoes or feet rarely occur.
