Description

Three-piece linkage

The present invention relates to a linkage door, and in particular to a hanging three-piece linkage door.

Conventional horizontal pull-type doors or windows usually include at least two door panels or window panels, and the rollers are used to position and walk on the rails. Generally, no linkage mechanism is provided, and each door panel or window panel needs to be moved one by one when switching, which is time-consuming, and the door is Large noise is also generated when the door collides.

For example, the Republic of China Announcement No. 384917 "Structural Improvement of the Sliding Door" is a new type of detachable guide frame at the bottom of the frame. The door frame and the guide frame are separated. When the door panel is installed in the guide groove of the upper frame, Then, the guide frame is embedded in the frame groove of the door frame, the guide frame can be easily inserted into the frame, and the sliding door can be easily detached from the frame through the guide frame; only the structure has no interlocking design, and the switch is inconvenient .

For example, the Republic of China Announcement No. 423575 "Modification of the Assembly Structure of the Shower Door", the structure is provided with a hooking device at the lower end of the door panel pillars on both sides of each door panel, by hooking the top of the hooking device respectively The guide groove of the frame and the auxiliary guide groove of the lower door frame are provided for guiding and positioning of the door panel, and a plurality of pulleys embedded in the upper frame slide rails disposed at appropriate positions on the door frames of the door panels, although having smooth sliding and simple The effect of dismantling the cleaning installation is only that the structure has no interlocking design, and the switch is inconvenient.

For example, the Republic of China Announcement No. M503459 "Modification of Window Frame Structure Improvement" is mainly composed of a window frame, a first door window, a second door window and a third door window, wherein the upper and lower positions of the window frame have a slide rail group, Two pulleys are disposed adjacent to one of the sliding rail groups, and a linkage is arranged between the pulleys, and the second door and the third door are respectively installed and adjacent to one side of the first door and adjacent to each other. Providing a first fixing portion and a second fixing portion for fixing the linking member, wherein the second door window or the third door window can be rotated through the connecting member through the connecting rod to drive the first door window Close or open at the same time. Although the patent enables three doors and windows to be linked, the structure cannot be easily transferred to the roller hanging door, and the sliding of the door piece in the window frame by the friction method is not smooth and is easy to generate noise.

In view of this, it is necessary to propose a hanging type interlocking door which has a smooth sliding of the roller and can be opened and closed on both sides to overcome the shortcomings of the conventional technology.
