Abstract
A sleigh-type rocking chair includes a pair of armrest/stile/riser assemblies joined to a pair of rocker/leg assemblies, a seat joined by mortise and tenon joints to the armrest/stile/riser assemblies, a front stretcher and a rear stretcher joined to each of the rocker/leg assemblies, a crest rail joined to an upper portion of the armrest/stile/riser assemblies, and a plurality of spindles joined to and extending upwardly from the seat and joined on the other end of the spindle to the crest rail. The assemblies, stretchers, seat, spindles and crest rail are preferably formed using a computer numerical control cutting device.
Claims3
A method of forming components of a sleigh-type rocking chair, the method comprising:
- forming a pair of armrest/stile/riser assemblies using a computer numerical control cutting device, each of said armrest/stile/riser assemblies formed having:
- a first cooperating part of an armrest/stile/riser joint part on a bottom inside portion thereof, and
- a form-fitted overhang on a bottom inside portion thereof;
- forming a pair of rocker/leg assemblies using a computer numerical control cutting device, each of said rocker/leg assemblies having:
- a second cooperating part of a rocker/leg joint part formed on a top outside portion thereof, said rocker/leg joint part configured to be fastened onto said first cooperating part on the bottom inside portion of said armrest/stile/riser joint part,
- a first cooperating seat mortise and tenon joint part on a top inside portion thereof;
- a rocker/leg assembly front mortise formed in a side portion thereof;
- a rocker/leg assembly rear mortise formed in a side portion thereof;
- forming a seat using a computer numerical control cutting device, said seat having:
- a second cooperating seat mortise and tenon joint part formed on a side portion thereof, said second cooperating seat mortise and tenon joint part configured to be press fitted into said first cooperating seat mortise and tenon joint part on the side portion of said rocker/leg assembly, and
- a plurality of spindle mortises formed in a top portion thereof;
- forming a front stretcher using a computer numerical control cutting device, said front stretcher to function as a monolithic tenon configured to be press fitted in each of said rocker/leg assembly front mortises;
- forming a rear stretcher using a computer numerical control cutting device, said rear stretcher to function as a monolithic tenon configured to be press fitted in each of said rocker/leg assembly rear mortises;
- forming a crest rail using a computer numerical control cutting device, said crest rail:
- functioning as a monolithic tenon, and
- having a plurality of crest rail mortises formed on the bottom portion thereof;
- forming a plurality of spindles using a computer numerical control cutting device, each of said spindles functioning as a monolithic tenon, one end of said spindles configured to be press fitted in said spindle mortises formed in said seat top portion and the other end of said spindle configured to be press fitted in said crest rail mortises.
