  Below, the usage method of the door handle structure 1 of this embodiment is demonstrated.

  As shown in FIG. 1, the door body 2 installed at the entrance and the like of the building is closed with the handle plate 9 being flush with the door body 2.

  When it is desired to ventilate the indoor air, as shown in FIGS. 2 and 5, a hand is inserted into the through hole 10, the handle plate 9 is gripped, and the door body 2 is opened perpendicularly. When ventilation is completed, a hand is inserted into the through-hole 10 to grip the handle plate 9 and close the door body 2 in a flush state.

  When the door body 2 is opened and closed, if the handle plate 9 is flush with the door body 2, a hand is inserted into the through hole 10 to grip the handle plate 9 and pull the door body 2 as it is. Push to open and close. Alternatively, after the handle plate 9 is in a state orthogonal to the door body 2, the handle plate 9 may be gripped and the door body 2 may be pulled or pushed as it is to open and close.

  In the door handle structure 1 of the present embodiment, the ventilation device can have a simple structure by providing the handle plate 9 with a ventilation function and a door body 2 opening / closing function.

  The door body 2 and the handle plate 9 can be easily opened and closed by the inserted hand by the through hole 10 provided in the handle plate 9. By opening the handle plate 9 so as to be orthogonal to the door body 2, ventilation can be performed while the door body 2 is closed. When ventilation is not performed, the handle plate 9 can be flush with the door body 2 so that the door body 2 can be closed in a flat state, and the protrusions are eliminated. Can be prevented, and design can be improved.

  The handle plate 9 is pivotally supported by a rotary damper 13 that rotates slowly with respect to the door body 2. Therefore, fast opening and closing of the handle plate 9 can be restricted to prevent a hand from being sandwiched between the opening 4 and the handle plate 9, thereby ensuring safety.

  In the present embodiment, the door body 2 is made of wood, but as a material, for example, a metal such as aluminum or all existing ones such as a synthetic resin can be used. Also, the door body 2 can be made of any existing structure such as a honeycomb structure.

  In this embodiment, the rotary damper 13 is used as means for restricting the opening and closing of the handle plate 9, but a member such as a ratchet having an intermittent rotation function may be used.

  Further, when the handle plate 9 is ventilated perpendicular to the door body 2, a small door closer, a door checker or the like is used to assist the handle plate 9 in order to maintain the orthogonal state of the handle plate 9. The door body 2 may be connected.

  The handle plate 9 is automatically flush with the door body 2 by using a small door closer, a door checker or the like so that the handle plate 9 is not left open with respect to the door body 2. In this way, the handle plate 9 and the door body 2 may be connected.

  A second embodiment of the door handle structure according to the present invention will be described with reference to the drawings. 7A and 7B, the left-right direction is the left-right direction, and the up-down direction is the up-down direction. The configurations other than those described below are the same as those in the first embodiment.

  The door 100a of the present embodiment includes a door handle structure 1a. In the door handle structure 1a, as shown in FIG. 7A, the handle plate 9a has a substantially S-shaped cross section in plan view and is disposed in the opening 4a. Both left and right ends of the handle plate 9a are curved in a substantially U shape so that the handle plate 9a can be operated in a state where it does not protrude from the door body 2 or is orthogonal to the door body 2. A gripping portion 18 formed so as to be grippable is provided. The overall length of the handle plate 9a in the vertical direction is formed so as not to exceed the overall length of the door body 2 in the vertical direction.

  In addition, the upper opening frame part 5a, the lower opening frame part 5b, the left opening frame part 5c, and the right opening frame part 5d are not provided in the outer edge of the opening part 4a.
