Abstract

A handle is disclosed connected to the top of the frame body of a carpet sweeper for driving the sweeper back and forth includes a slightly bent neck in the vicinity of its lower end connected to the frame body. A pin extending from the lower end of the neck is journaled in a bearing hole formed in a short head for connecting the neck to a connecting pin extending across a groove in a top center portion of the frame body. The bending of the neck permits the handle to be swivelled to a low position relative to the frame body.

Claims

1. In a carpet sweeper including a frame body means having an open under face and a closed top face with a groove in its center portion, a rotary brush means transversely supported at the center of the open under face of said frame body means, dust receptacle means positioned in front and rear of the rotary brush in proximity thereto, and pivotally movable from a closed position to an open position, rolling wheels disposed at lower portions of opposite sides of said frame body means for contact with the floor, driven wheel means in frictional contact with the rolling wheels for driving the rotary brush, and a handle with upper and lower portions and having a grip and connected to the top of said frame body means for moving said frame body means backwards and forwards, the improvement comprises:

said handle being provided with means so that when a rightward or leftward twisting pivotal movement is given to the grip of said handle and the frame body means is subsequently pushed forward, then the direction of travel of the frame body means follows a curved path; and

the lower portion of the handle proximate to its connection with said frame body means being slightly bent to form a bent neck portion and the bent neck portion having pivoting means to pivotally connect its lower part to said frame body means so as to render said bent neck portion swivellable with resPect to said frame body means.

2. The apparatus as set forth in claim 1 wherein said bent neck portion is pivotally connected to the frame body by a pin fitted in a bearing hole, said pin projecting from the lower end of said neck portion, a short head disposed between the frame body means and said bent neck portion for connection with a connecting pin extending across said groove in the top center portion of said frame body means, with said bearing hole being formed in the other end of said short head and a sleeve fitted in the bearing hole for providing a frictionless bearing for said pin.

3. The apparatus as set forth in claim 2 wherein at least one slanting planar side face is formed at the lower end of said short head and a plate spring means acting to push the planar face upward is embedded in the bottom of said groove in the top center portion of said frame body means.

4. The apparatus as set forth in claim 1 wherein means is provided for preventing the swivelling movement with respect to said frame body means when said handle is brought to its upright position on said frame body means.

5. The apparatus as set forth in claim 4 wherein a plate spring means is disposed in the groove in the top of the frame body means and has vertical members biased to clamp said short head at its opposing side faces, said vertical members elastically supporting the opposing sides of said bent neck portion when the handle is brought to its upright position on said frame body means.
