Special consideration is suitable for so-called bi-directional folded door, and sometimes referred to as double door, this door generally includes to pass through hinge The more than two fans or panel that chain etc. links together, fan or panel can fold or be unfolded to open completely, partly It opens or is closed completely.This bi-directional folded door using simple rail mechanism operate, rail mechanism along door side up and down Edge extend, and adjacent fan can by one, be usually more than two hinges it is secured to one another.In recent years, this two-way folding Folded door becomes increasingly popular, and can especially be opened in door and not interrupt the household room for entering garden space inside room to provide In.

It is fanned including more than two connections as it is known in the art, term " bi-directional folded door " or " double door " are covered Or panel（Panel including Odd number and even number）Door, window etc., and mentioned herein should do respective explanations.This Kind closure member is also known as multidirectional folding door sometimes.

Due to the mechanical function of bi-directional folded door, the gap when door is opened completely between adjacent door leaf needs to remain absolutely To minimum, maximizes so that door opens aperture and ensures that door leaf can be stacked to close alignment when door is opened completely, It is preferably parallel to one another.For this reason, it is expected that any handle on door has low profile.Equally, it is maintained at folding in handle In the case of except panel, considers from aesthetic and security standpoint, be similarly desired to have low profile.However, as described above, having The handle of low profile is generally difficult to operate, and the shortage in the gap between handle grip and panel or frame can cause in hand User's scratch his or her joint when handle is rotated.

Summary of the invention

Therefore, the purpose of the present invention is to provide the Handleset for door etc. in particular for bi-directional folded door, this hands Handle is easy to operate, and will not substantially hinder the stacked of door or fold, or will not be from end fan when door is in open configuration Exposure is significantly stretched out.

According to first scheme, present invention is accordingly directed to a kind of door leafs for being assembled to the fan of bi-directional folded door etc. Handleset, the component includes：Backboard is fixed to doorframe；Rotatable knob main shaft, can be operated on knob with The knob is moved to the position of engagement or disengaged position according to direction of rotation；And handle, have and is grabbed with what bar portion was adjoined Portion is held, wherein the bar portion is slidably mounted on the main shaft, for moving between the first position and the second position, On the first position, the grip part is close to the backboard and is maintained on the backboard to prevent the handle from rotating, On the second position, the bottom interval of the grip part and the handle is opened to be carried between the grip part and the backboard For finger joint gap and the handle is discharged so that it is rotated.

Through the invention, user can in rotational handle with wheel handle grip before operating knob far from door leaf, And his/her finger joint when handle rotates therefore is avoided to scratch onto fan.After the operation of knob, handle can return to Initial first position.It will be appreciated that when handle returns to first position, if main shaft is not by rotating back into handle Its initial initial position and counter-rotating first, then knob will remain on disengaged position, be normally retracted to the lateral edges of fan Or in its framing component.Alternatively, handle can rotate back into its initial initial position before handle returns to first position, So that knob is stretched out from frame again.

In typical bi-directional folded door arrangement, each fan includes surrounding inserts of glass（It is such as single, two or three Inserts of glass）Aluminum, uPVC coating aluminums or wooden frame so that panel section is more very thin than the frame of surrounding.For So that the fan adjacent when door is in open configuration positions in parallel with each other, handle grip is preferably general plane type.
