AI Technical Summary
The existing door bodies shrink as the wood ages, causing the surface material to be pulled inward, forming grooves, damaging the appearance, and requiring additional time and effort to form a ventilated groove.
The thickness of the crossbar is designed to design the other parts of the door body and place it in the center of the surface material to avoid direct bonding to the surface material, so as to not affect the flatness of the surface material when the crossbar ages, and at the same time, the gap between the crossbar and the door body is used as a natural ventilation groove.
Effectively avoid the problem of surface material grooves due to crossbar aging, simplify the manufacturing process, reduce the need for additional ventilation groove formation, and improve production efficiency.

Abstract
Description
[Technical field]
[0001] The present invention is Body It relates to a manufacturing method. [Background technology]
[0002] A conventional door body has the structure shown in Figures 10 to 14. The door body 100 comprises a crosspiece member 101 consisting of left and right vertical crosspieces 102, 103, upper crosspieces 104 and lower crosspieces 105 which join the left and right vertical crosspieces 102, 103 at the top and bottom, metal square pipes 106, 107 arranged inside and along the left and right vertical crosspieces 102, 103 within the crosspiece member 101, a horizontal crosspiece 108 arranged between the left and right metal square pipes 106, 107, a honeycomb-structured core material 109 housed within the crosspiece member 101, and surface materials 110 attached to the front and back of the crosspiece member 101, etc.
[0003] The crosspiece members 101, horizontal crosspieces 108 and surface material 110 are made of wood, and the upper crosspieces 104 and lower crosspieces 105 are each provided with an air inlet / outlet groove 111 for allowing air to circulate between the inside and the outside, while the horizontal crosspieces 108 are provided with an air circulation groove 112 for allowing air to circulate inside. The crosspiece members 101, the metal square pipes 106 and 107 and surface material 110 attached to both the front and back sides of the horizontal crosspieces 108 are bonded with adhesive 113 applied by a roller.
[0004] In this configuration, the crosspiece member 101 and the horizontal crosspiece 108 have the same thickness. That is, as shown in Fig. 12, the thickness L1 of the crosspiece member 101 consisting of the vertical crosspieces 102, 103, the upper crosspiece 104, and the lower crosspiece 105 is the same as the thickness L2 of the horizontal crosspiece 108. The thickness L3 of the metal square pipes 106, 107 is thinner than the thickness L1 of the crosspiece member 101 and the thickness L2 of the horizontal crosspiece 2. Furthermore, the surface material 110 is attached to the front and back surfaces of the crosspiece member 101, the metal square pipes 106, 107, and the horizontal crosspiece 108 using adhesive 113 applied by a roller.
[0005] However, in the case of the above-mentioned construction, since the horizontal rail 108 is made of wood, when it shrinks over time and its thickness decreases, the surface material 110 adhered to the outside of the horizontal rail is pulled inward and recessed, resulting in a step as shown in Figure 14. When this happens, the appearance is significantly impaired and becomes unsightly.
[0006] Furthermore, the thickness of the horizontal rail 108 is the same as that of the rail member 101, and there is no gap between them and the surface material 110 bonded to the outside. For this reason, it is necessary to form air circulation grooves 112 for circulating air inside the horizontal rail 108 on the surface of the side that comes into contact with the surface material 110. This also requires time and effort. Summary of the Invention [Problem to be solved by the invention]
[0007] The present invention has been made in consideration of the above points, and is directed to a cross beam having a thickness thinner than that of the cross beam member. and position it in the center of the surface material on both sides. At the same time, the door body is designed not to be bonded to the surface material, so that even if the horizontal bar shrinks over time and its thickness decreases, the surface material will not be dented at that portion, preventing the door from becoming unsightly, and saving the time and effort required to form air circulation grooves as in the past. Effectively The present invention aims to provide a method for manufacturing a door body that can be manufactured efficiently. [Means for solving the problem]
