Abstract
A jar opener including a lid clamp adapted to clamp onto a lid of a jar; a motor connected to the lid clamp; and a frame having the motor connected thereto. The frame includes at least three frame sections which are vertically slidingly connected relative to one another in series in a general telescoping fashion. The motor is connected to a top one of the frame sections.
Claims37
A jar opener comprising:
- a lid clamp adapted to clamp onto a lid of a jar;
- a motor connected to the lid clamp;
- and
- a frame having the motor connected thereto, the frame comprising at least three frame sections which are vertically slidingly connected relative to one another in series in a general telescoping fashion, wherein the motor is connected to a top one of the frame sections.
A jar opener comprising:
- a lid clamp adapted to clamp onto a lid of a jar;
- a motor connected to the lid clamp;
- a frame comprising at least two frame sections vertically slidingly connected to each other, a top one of the frame sections having the motor connected thereto;
- and
- at least one spring located between portions of the frame sections for biasing the top frame section and the motor in an upward direction.
A jar opener comprising:
- a frame;
- a motor connected to the frame;
- a first adjustable clamp connected to the motor;
- and
- a second adjustable clamp connected to the frame,
- wherein the second adjustable clamp comprises a stationary gear and at least two second jaw members having teeth intermeshed with teeth of the stationary gear, and wherein the second jaw members are adapted to rotate about the stationary gear to move clamping surfaces of the second jaw members inward and outward relative to the stationary gear.
A jar opener comprising:
- a frame;
- a motor connected to the frame;
- and
- a clamping system connected to the frame and the motor, the clamping system comprising a first jar engagement assembly connected to the motor and a second jar engagement assembly connected to the frame,
- wherein the second jar engagement assembly comprises generally opposing jaw members adapted to be moved to a clamping position onto a jar by rotational movement of the second jaw assembly, transmitted to the second jaw assembly by the jar, while the jar is rotated on the second jaw assembly.
A method for opening a jar in a motorized jar opening apparatus comprising steps of:
- rotating the jar;
- and
- automatically closing a jar clamp onto the jar as the jar is rotated, the step of automatically closing comprising the jar clamp being axially rotated by contact with the rotating jar to move clamping surfaces of jaw members of the jar clamp inward towards each other.
A method for opening a jar in a motorized jar opening apparatus comprising steps of:
- rotating a first jar engagement assembly by a motor while the jar remains relatively stationary, the first jar engagement assembly being located against a first portion of the jar;
- closing the first jar engagement assembly onto the first portion of the jar as the first jar engagement assembly is rotated relative to the first portion;
- subsequently rotating the first jar engagement assembly and the jar together as a unit;
- and
- automatically moving a second jar engagement assembly from an open position to a closed position onto a second portion of the jar as the jar is rotated, the second jar engagement assembly being located against the second portion and being moved to the closed position by rotation of the jar.
