Description

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

2. Description of the Related Art Conventionally, a so-called flash panel-like 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 a solid material or the like. Since the vertical beam members constituting such a core material are formed of a wood-based material, there is a problem that warpage is likely to occur and warpage is likely to occur in the door panel itself.
For example, Patent Document 1 below discloses a flash panel in which outer plates are provided on both sides of a panel frame having left and right vertical frame portions and upper and lower horizontal frame portions that are framed in a rectangular shape. In addition, the flash panel is configured such that a groove-shaped reinforcing metal plate whose lateral cross-sectional shape opens laterally is covered on an inner vertical rail among a plurality of vertical rails constituting the vertical frame portion.

In other words, the reinforcing member 21 is provided so that the latch portion 3 and the central portion obtained by dividing the reinforcing member 21 into three in the longitudinal direction overlap each other when viewed in the door width direction.

  In the present embodiment, the reinforcing member 21 is provided so as to be spaced from the lower horizontal frame portion 16. In other words, the reinforcing material 21 is not provided until the vicinity of the lower end portion of the door panel 1, and a portion where the reinforcing material 21 does not exist is provided on the lower end side of the door panel 1. That is, in this embodiment, it is set as the structure which provided the site | part which does not exist the reinforcing material 21 in the upper and lower sides of the door panel 1. FIG. The lower end side door height dimension H5 along the door height direction from the lower end of the reinforcing member 21 to the lower end face of the door panel 1 is higher than the upper end side door height dimension H6 along the door height direction from the upper end of the reinforcing member 21 to the upper end face of the door panel 1. Small. The lower end side door height dimension H5 may be about 1/2 to 1/5 of the upper end side door height dimension H6.

Moreover, in this embodiment, the length dimension H4 of the vertical crosspiece 20 and the reinforcing material 21 is made into the mutually substantially the same dimension. That is, the vertical crosspiece 20 is not provided over the entire length of the door panel 1, but the length dimension H4 is smaller than the door height dimension H1 and is shifted toward the lower end side.
