Description

The present invention relates to a door panel that is rotatably supported on the hanging side of the opening.

Conventionally, a so-called flash panel-shaped door panel having a structure in which a face material is attached to a core material is known because the weight can be reduced as compared with a door panel made of solid wood or the like. Since the vertical crosspiece constituting such a core material is formed of a wood-based material, there is a problem that warpage is likely to occur and the door panel itself is likely to be warped.
For example, Patent Document 1 below discloses a flash panel in which outer surface plates are provided on both sides of a panel frame having left and right vertical frame portions and upper and lower horizontal frame portions framed in a rectangular shape. Further, this flash panel has a configuration in which an inner vertical rail among a plurality of vertical rails constituting the vertical frame portion is covered with a groove-shaped reinforcing metal plate having a cross-sectional shape that opens laterally.

However, when the flash panel as described above is used as a hinged door (high door) having a relatively large door height dimension, the handle and the latch portion are provided at positions closer to the lower end side of the panel. Therefore, it is conceivable that when the door is closed, the upper end side of the door end side end portion is likely to vibrate (chatter vibration), and abnormal noise is likely to occur. In other words, if the latch part of the panel that moves to the closed side is inserted into the latch receiver and the panel comes into contact with the door stop, the part away from the latch part on the door end side of the panel will bounce and come into contact with the door stop. Tends to vibrate in the door thickness direction so as to repeat. It is considered that such vibration becomes remarkable in the upper portion which is longer than the lower portion of the latch portion, and further improvement is desired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door panel which can reduce weight, suppress warpage, and reduce abnormal noise generated when the door is closed. There is.

In order to achieve the above object, in the door panel according to the present invention, face materials are provided on both sides of a panel core material having a vertical crosspiece formed of a wood-based material in the door thickness direction, and the hanging side of the opening is provided.
