[0001] The present invention relates to a door device, and in a preferred embodiment, it relates to an entrance door.
Background Art
[0002] In an entrance door or the like, a door device with sleeves provided adjacent to the door body may be adopted. In the door device with sleeves, the vertical frame on the door tip side of the door device is formed from a so-called side post (Patent Document 1). In particular, in an entrance door, the appearance seen from the outdoor side is important. However, in the closed posture of the door body, the eye is likely to be drawn to the door tip side part of the door body, and also when the door body is opened and closed, the eye is likely to be drawn to the door tip side part (where the handle is located).
[0003] At this time, if the surface material of the door body and the material of the side post are different, a difference in texture or material feeling may occur due to the different materials, and the unity of the combination of the vertical frame on the door tip side and the door tip side part of the door body may be subtly impaired. For users who require a sophisticated design, this is a problem to be solved.
