Description

[Detailed description of the invention] The present invention is directed to door devices.

Conventional door devices are designed to lock the door when it is completely closed, and there is no structure that can hold the door in an appropriate open state and prevent it from opening any further. However, during the summer months, it is preferable to leave the door slightly open for ventilation. Therefore, traditionally a door chain or string was used between the door and the entrance frame.

To prevent the door from closing, items were held between the door and the door left ajar. However, in this case, it is difficult to change and maintain the opening amount of the door as appropriate, so it is difficult to adjust the opening amount of the door, and in addition, there are problems in that it is time-consuming and the appearance is poor.

The present invention was made in view of the above circumstances, and includes a door, a frame for holding the door, and a plurality of retainers installed horizontally on at least one of the door and the frame and extending away from the door or the frame. A door half-open state holding member having mating portions provided at appropriate intervals, and a holder that engages with an appropriate engagement portion of the door half open state holding member to hold the door at an appropriate opening amount. The gist of this paper is the door device that is currently available.

In other words, this door device can solve all of the above-mentioned problems because it can hold the door while changing its opening position as appropriate.
