Description

Folding door with door lock

The present invention relates to a folding door having a door lock, and more particularly to a folding door that increases structural strength and reduces manufacturing costs.

A commercially available folding door has two relatively pivotable door panels. When the folding door is closed, the two door panels are arranged in parallel in a straight line. When the folding door is opened, the two door panels can be overlapped together, thereby reducing the space occupied by the door opening. Therefore, such a folding door is suitable for use in a small space (for example, a bathroom).

However, such a folding door is often required to be combined with an aluminum or metal frame on the four sides of the door panel due to insufficient strength of the door panel structure or material properties (such as a glass door) for reinforcing the structural strength of the door panel of the folding door. The manufacturing cost of the folding door is high and the manufacturing process is cumbersome.

Further, some commercially available folding doors use a latch to provide a locking function, and when the folding door is in the closed state, the latch is displaced to engage with a latch hole of the door frame of the pivoting folding door so that the folding door cannot be opened. However, in general, the structure of such an operating latch needs to be disposed in one of the metal frames of the door panel, resulting in a high manufacturing cost of the folding door and a cumbersome manufacturing process. Furthermore, the operating lever for operating the latch is usually disposed at a position near the top of the folding door, which is not convenient in operation. In addition, the structure of the operating latch usually needs to be assembled with a folding body after the additional casing is assembled into a set of latching structures, which also increases the manufacturing cost of the manufacturer. And, in order to operate the folding door to open or close, a grip is usually provided on each of the two outer sides of the folding door, which also increases the manufacturing cost of the manufacturer.
