Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a window frame made of synthetic resin.

[Conventional technology]

As shown in Jitsukasho (TO-105786), a rail mounting part is integrally formed on the inner surface of a hollow body to form a synthetic resin lower frame, and a hollow body is formed on the inner surface of the hollow body of the same shape as the lower frame. The protrusion is integrally formed to form a vertical frame made of synthetic resin, and the hollow body of the lower frame and the ends of the hollow body of the vertical frame are cut at 45 degrees, and the lower frame and vertical frame are joined by butting and welding. Connected synthetic resin window frames are known.

[Problem to be solved by the invention]

With such a synthetic resin window frame, the hollow body of the lower frame and the hollow body of the vertical frame are simply welded together, and the lava area is smaller than the total cross-sectional area of the lower frame and vertical frame, so the welding strength is low. If this happens, the strength of the connection between the bottom frame and the vertical frame may decrease, resulting in deformation, etc.

Therefore, an object of the present invention is to provide a synthetic resin window frame that can solve the above-mentioned problems.

[Means and effects for solving the problem] Cut the hollow body of the lower frame and the ends of the rail attachment part at 45 degrees, cut the hollow bodies and the protruding parts of the left and right vertical frames at 45 degrees, and cut each of the ends. This is a synthetic resin window frame whose end faces are butted and welded together.This increases the welding area between the bottom frame and the left and right vertical frames, increasing the strength of the connection.
