Abstract

The chair frame of a swivel rocker is slidably mounted via a pair of sleeves on the arms of a pair of flexures mounted on the base of the rocker to allow the chair frame to be moved into different positions on the flexures. Bolts are used to secure the sleeves in place on the flexures. Movement of the sleeves along the flexures changes the position at which the weight of an occupant is transferred to the flexures and thereby changes the bending moments imposed on the flexures.

Claims

1. An adjustable rocker comprising

a base;

a chair frame;

a pair of parallel flexures for supporting said chair frame on said base for rocking in a vertical plane; and

means for adjusting the position of said chair frame on said flexures relative to said base.

2. An adjustable rocker as set forth in claim 1 wherein said means includes a pair of sleeves, each said sleeve being secured to said chair frame and telescopically receiving a respective one of said flexures therein;

and securing means for releaseably securing each respective flexure in a respective sleeve in a selected one of a plurality of positions.

3. An adjustable rocker as set forth in claim 2 wherein each said sleeve has a slot with a plurality of aligned recesses therein and said securing means is a bolt passing through said respective sleeve and threaded into a respective flexure and having a head received in mating relation in a selected one of said recesses.

4. An adjustable rocker as set forth in claim 3 wherein each bolt is of a threaded length sufficient to remain in threaded engagement with said respective flexure with said head thereof out of mating engagement with said sleeve to allow said sleeve to be movable relative to said flexure while blocking said chair frame from moving off said flexures.

5. An adjustable rocker comprising

a base;

a chair frame; and

a connection unit mounting said chair frame on said base, said connection unit including a pair of parallel flexures for supporting said chair frame on said base for rocking in a vertical plane and means for horizontally adjusting the position of said chair frame on said connection unit relative to said base.

6. An adjustable rocker as set forth in claim 5 wherein each flexure is of U-shape with a pair of horizontally disposed legs.

7. An adjustable rocker as set forth in claim 6 wherein said means includes a pair of sleeves, each said sleeve telescopically receiving a leg of a respective one of said flexures therein;

and securing means for releaseably securing said leg of each respective flexure in a respective sleeve in a selected one of a plurality of positions.

8. An adjustable rocker as set forth in claim 7 wherein each said sleeve has a slot with a plurality of aligned recesses therein and said securing means is a bolt passing through said respective sleeve and threaded into said leg of a respective flexure and having a head received in mating relation in a selected one of said recesses.

9. An adjustable rocker as set forth in claim 8 wherein each bolt is of a threaded length sufficient to remain in threaded engagement with said respective flexure with said head thereof out of mating engagement with said sleeve to allow said sleeve to be movable relative to said flexure.

10. An adjustable swivel rocker comprising

a base having an upstanding stem;

a chair frame; and

a connection unit connecting said chair frame to said base;

said connection unit including a vertical pivot pin rotatably mounted in said stem of said base for rotatably supporting said chair frame on said base, a pair of parallel flexures secured between said base and said chair frame for supporting said chair frame on said base for rocking in a vertical plane, and means for horizontally adjusting the position of said chair frame on said connection unit relative to said base.

11. An adjustable swivel rocker as set forth in claim 10 wherein said means includes a pair of sleeves, each said sleeve telescopically receiving a respective one of said flexures therein;

and securing means for releaseably securing each respective flexure in a respective sleeve in a selected one of a plurality of positions.

12. An adjustable swivel rocker as set forth in claim 11 wherein each said sleeve has a slot with a plurality of aligned recesses therein and said securing means is a bolt passing through said respective sleeve and threaded into said respective flexure and having a head received in mating relation in a selected one of said recesses.

13. An adjustable swivel rocker as set forth in claim 11 wherein each said sleeve has a pair of ribs therein for slidably mounting said respective sleeve on a respective flexure.
