The handle device 100 includes a housing 10 housed in a door frame 2, an operating body 20 provided inside the housing 10, and a helical A first rod 41 and a second rod 42 interlocking with the helical pinion gear 30 and a shaft 51 penetrating through the center of the helical pinion gear 30, And is fixedly connected to the handle bracket 60 provided on the outer circumferential surface of the shaft 51 of the handle 50 by the fixing member 15, And a projection (21).

Hereinafter, the constituent elements and actions of the present invention as described above will be described in detail as follows.

The present invention is largely composed of a housing 10, an operating body 20, a helical pinion gear 30, a first rod 41 and a second rod 42, a handle 50, and a handle bracket 60 .

The housing 10 is built in the frame of the door 2 and has a plurality of concave and convex portions formed on the outer surface thereof so as to penetrate the upper and lower portions thereof. The housing 10 is coupled to the frame of the door 2, And a handle bracket 60 is provided at the upper and lower portions of the through hole so as to allow the shaft 51 to penetrate through the other side surface of the through hole, (15).

The operating body 20 is slidably guided into the housing 10 and has a through hole formed at one side thereof to allow the shaft 51 of the handle 50 to pass therethrough and a stop member 80 And a fixing protrusion 21 is formed at the upper and lower portions of the through-hole formed in one side surface.

The fixing protrusions 21 are fixed to the handle brackets 60 by the fixing members 15 to effectively prevent the handle 50 from shaking due to the opening and closing operations of the door 2 continuously to be.

The helical pinion gear 30 is disposed at a central portion of the operating body 20 and cooperates with the gears 41a and 42a of the rods 41 and 42 to cooperate with the rods 41 and 42, In a vertical vertical direction.

The first rod 41 and the second rod 42 are coupled at one end to engage with the lock bar 80 and at the other end to the helical pinion gear 30, And the lock bar 80 is vertically moved in accordance with the rotation action of the helical pinion gear 30 to move the lock bar 80 to lock the door 2. [

A shaft 51 is coupled to the tip of the handle 50 and the shaft 51 is engaged with the helical pinion gear 30 so that the helical pinion gear 30 is rotated in the forward or reverse direction So that the door 2 can be easily locked or unlocked by a person simply holding the handle 50 and rotating the door 2 to easily open and fold the door 2.
