Abstract
The present invention relates to a locking assembly for a rocking chair. The locking assembly includes a pair of jaws mounted to the body-supporting portion of the chair and a set of pins mounted to the chair base portion of the chair. The jaws are operable to engage a selected pin to lock the body-supporting portion of the chair relative the chair base portion in a position that corresponds to the selected pin. The jaws include gripping faces that spread apart to define a recess when the locking assembly is operated. At the same time the gripping faces move toward the pin to cause the pin to enter the recess such that the pin becomes wedged in the recess.
Claims58
A locking assembly for a rocking chair, said locking assembly being suitable for retaining a body supporting portion of the chair relative to a chair base portion of the chair in a certain position, said locking assembly comprising:
- a first locking assembly component for connection to one of the body supporting portion and the chair base portion;
- a second locking assembly component for connection to the other of the body supporting portion and the chair base portion;
- said second locking assembly component including a pin;
- said first locking assembly component including:
- i. a pair of jaws;
- ii. a linkage coupled to at least one of said jaws, at least one of said jaws being responsive to a first movement of said linkage to undergo displacement with relation to the other jaw such as to cause engagement of said pin between said jaws, at least one of said jaws being responsive to a second movement of said linkage to cause release of said pin between said jaws.
A rocking chair, comprising:
- a body supporting portion;
- a chair base portion, said body supporting portion capable to rock with respect to said chair base portion;
- a locking assembly including:
- a first locking assembly component for connection to one of said body supporting portion and said chair base portion;
- a second locking assembly component for connection to the other of said body supporting portion and said chair base portion;
- said second locking assembly component including a pin;
- said first locking assembly component including:
- i. a pair of jaws;
- ii. a linkage coupled to at least one of said jaws, at least one of said jaws being responsive to a first movement of said linkage to undergo displacement with relation to the other jaw such as to cause engagement of said pin between said jaws, at least one of said jaws being responsive to a second movement of said linkage to cause release of said pin between said jaws.
A chair, comprising:
- a. a body-supporting portion, including:
- i. a seat;
- ii. a backrest;
- b. a chair base portion, said body supporting portion capable to move with respect to said chair base portion;
- c. a locking assembly, including:
- i. a first locking assembly component mounted to one of said body-supporting portion and said chair base portion;
- ii. a second locking assembly component mounted to the other of said body-supporting portion and said chair base portion;
- d. a linkage including a strip of resilient material mounted to said backrest, said strip of resilient material having a resiliency such that:
- i. when an occupant applies pressure on said backrest said strip is deformed rearwardly from an original position;
- ii. when the pressure applied by the occupant ceases, said strip returns to said original position;
- e. said linkage operatively connected to said locking assembly to cause:
- i. engagement of said first and second locking assembly components for preventing movement of said body supporting portion, relative to said chair base portion when said strip is in said original position;
- ii. release of the engagement of said first and second locking assembly components when said strip is deformed rearwardly from said original position.
