Abstract
A hinge has a shaft, a rotating bracket, a stationary bracket, a rotating positioning element and a stationary positioning element. The rotating bracket is mounted securely on the shaft and is attached to a cover of an electrical appliance. The stationary bracket is mounted around the shaft and is attached to a base of the electrical appliance. The rotating positioning element is mounted securely on the shaft and has two positioning protrusions. The stationary positioning element is mounted securely on the stationary bracket and has two positioning detents. The positioning detents selectively engage the positioning protrusions to keep the cover from bumping against the base.
Claims6
A hinge comprising:
- a shaft having
- a head having a first side and a second side;
- a fastening rod formed axially on the first side of the head and being non-circular;
- an assembling rod formed axially on the second side of the head and having a distal end;
- and
- a mounting rod formed axially on the distal end of the assembling rod and being non-circular;
- a rotating bracket mounted securely on fastening rod of the shaft;
- a stationary bracket being L-shaped, mounted around the assembling rod of the shaft and having
- a fastening wing;
- a mounting wing being perpendicular to the fastening wing and having a top surface, a first side and a second side;
