Reinforcing bar binder
In a reinforcing bar binder in which a wire reel around which a reinforcing bar binding wire is wound is rotatably housed in a housing chamber in a binder main body, the wire is pulled out from the wire reel and wound around reinforcing bars, and the reinforcing bars are bound by twisting the wound portion, an opening is formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion formed on the wire reel. On the one side wall, a reel receiver which is supported so as to come into and come out from the opening is fitted to the shaft receiving portion of the wire reel when it is pushed into the inside of the side wall. A reel stopper moves along the wall surface of the one side wall and can engage with the reel receiver fitted to the shaft receiving portion. A leaf spring urges the reel stopper engaged with the reel receiver to the pushing-in side.
1. A reinforcing bar binder comprising:
a housing chamber in which a wire reel is rotatably housed;
an opening formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion of the wire reel;
a reel receiver which is provided on said one of the side walls so as to come out from and come into the opening and fit to the shaft receiving portion of the wire reel when the reel receiver is pushed into an inside of said one of the side walls;
a reel stopper which is movable along a wall surface of said one of the side walls to engage with the reel receiver fitted to the shaft receiving portion;
an elastic body which urges the reel stopper engaged with the reel receiver in a direction so that the reel stopper is pushed-in toward the wire reel;
a concave portion provided on one of the elastic body and the reel stopper; and
a convex portion provided on the other of the elastic body and the reel stopper and capable of resiliently engaging with the concave portion.
2. The reinforcing bar binder according to claim 1 , further comprising:
a metallic cover provided on an engaging portion between the reel receiver and the reel stopper.
3. A reinforcing bar binder, comprising:
a housing chamber in which a wire reel is rotatably housed;
an opening formed through one of both side walls of the housing chamber at a position corresponding to a shaft receiving portion of the wire reel;
a reel receiver which is provided on said one of the side walls so as to come out from and come into the opening and fit to the shaft receiving portion of the wire reel when the reel receiver is pushed into an inside of said one of the side walls;
a reel stopper which is movable along a wall surface of said one of the side walls to engage with the reel receiver fitted to the shaft receiving portion; and
an elastic body which urges the reel stopper engaged with the reel receiver in a direction so that the reel stopper is pushed-in toward the wire reel,
wherein the reel stopper includes a lever part and a stopper part,
wherein the stopper part moves to engage with and disengage from the reel receiver by operating the lever part, and
wherein the elastic body is adapted to push the lever part so that the stopper part engaged with the reel receiver pushes the reel receiver toward the wire reel.
