104	Methods of manufacturing curved staircases and staircases produced	US977268	1992-11-16	US5347774A	1994-09-20	Lynn H. Smith
Improved methods of fabricating at least partially curved staircases include a first method in which preformed step structures have treads with curved slots formed in the underside of the ends which define a path for insertion of top edge segments of thin starter strips. The slots are collectively configured to laterally deflect the inserted starter strips in a manner longitudinally conforming them to at least partially curved paths of the overall stringer structures in the completed staircase. The stringers are then laterally built up and completed by securing reinforcing structures to the side surfaces of the laterally deflected strips. A second method uses preformed cooperating treads and risers themselves as a form which defines an at least partially curved path for the stringers. Simple temporary supports both position the cooperating treads and risers and provide a solid support for laying up strips from the inside out to form stringers to support the stair and back finishing strips along curved paths defined by the cooperating treads and risers wherein the finishing strips have edges configured to interengage the outer ends of the cooperating treads in a rigid assembly and form smooth sides of the staircase. The procedure is designed to allow the stringers to be made from flexible strips which are conveniently boxable and shippable because smooth butt joints are made while the ends are solidly supported and thus prefabricated staircase kits are made practical.

106	Staircase stringer fabricating apparatus	US765371	1985-08-12	US4673011A	1987-06-16	James M. Lapeyre; Christopher G. Greve
A staircase stringer fabricating apparatus includes a structural machine frame having a carriage moveably mounted with respect to the frame for supporting an elongated stringer work piece. A track mounted upon the structural frame defines a guide for the carriage so that the carriage can move on a controlled path with respect to the frame. Material working stations, such as wood routers, welding torches or the like are spaced upon the machine frame for simultaneously preparing the work piece with selectively spaced apart tread assembly positions that define the horizontal stair step positions (including the spacing and angular positions) upon the stringer during use. The tread positions are preferably formed responsive to the movement of the carriage and work piece upon the track along the controlled path so that the work stations traverse the work piece. In the preferred embodiment, the wood routers simultaneously make cuts with equal separation in the wooden stringer work piece to which individual treads can be affixed.
107	Apparatus for automatic nailing of preassembled wood stairs	US3733020D	1971-12-29	US3733020A	1973-05-15	INGRAM H
Precut and grooved stringers, precut treads and risers are temporarily secured together in the form of a stair which is then received by an apparatus which automatically indexes the stair step by step past left, right and top banks of nailers which nail the stringers and risers to the treads to produce a permanently secured stair.

112	Step for a stairway and method for making same	US331963	1994-10-31	US5531048A	1996-07-02	Gary L. Darling
A method is provided for manufacturing or converting a stairway made from wood-composite materials to a stairway which appears for all intents and purposes to be made from architectural solid wood materials. The method contemplates providing one or more stair treads and risers interconnected on one or more support stringers. This assembly may be preexisting or constitute new construction. With the stair treads and risers in place, sheets of veneer overlay are provided which are scribed and trimmed to cover at least the end portions of each tread, riser, or both, leaving the central high traffic portion of the tread exposed. Once trimming is complete, the veneer overlays are adhered to each tread or riser. With respect to the stair treads, it is preferred that a portion of the veneer is rolled around the leading edge of the tread and fastened to the underlying surface. Any irregularities or gaps in the joints between the treads, risers, and veneer may be concealed behind strips of molding. Additional trim pieces are provided where the ends of the treads are opened or exposed, as opposed to being concealed between walls and/or trim stringers. The invention also provides for a kit for making a staircase appear as if it were made from architectural woods as well as the staircase including these components. Portions of the stairway where the composite wood materials remain exposed may be concealed by carpet runners or the like.
113	Apparatus and method for producing a bent laminate	US760735	1991-09-16	US5203948A	1993-04-20	Alex Suska
An apparatus and method is disclosed for the bending and pressing of laminations into 2-dimensional or 3-dimensional curves. The apparatus includes a pair of spaced apart rotatable clamps for the clamping of the laminations at spaced apart locations. At least one of the clamps is movable towards the other clamp. Counterclockwise rotation of the clamps bends the laminations held by the clamps. A clamping force of at least one of the clamps is controllable so that the laminations may be bent while a mutual sliding movement of the laminations in at least one clamp is permitted. The laminations are bent to a radius larger than a desired radius. At this point, the clamping pressure is increased to prevent the mutual sliding movement so that upon further bending of the laminations, the outer laminations are pressed against the inner laminations at a substantially evenly distributed force along the bent section of the laminations. The apparatus is easily adaptable to produce different shapes and sizes of 2- and 3- dimensional curvatures and permits the fast and economical bending and compression of a workpiece having individual layers.
114	Method and apparatus for forming stringers for free-standing circular staircases	US335992	1989-04-10	US4918799A	1990-04-24	Louis Benedetti
A structure on which stringers for a free-standing circular staircase are formed in accordance with a time-saving method is disclosed. The structure comprises upper and lower metal patterns connected by vertical beams. The patterns have a plurality of rays attached to a central hub. The beams are attached to equidistant rays at a given distance from the center of the respective pattern. Clamps are affixed at successively higher positions along the perimeter of the circle formed by the beams that hold the stringer while it is being laminated with epoxy resin, until it has become rigid.Separate sets of beams may be used to form inner and outer stringers for a staircase, or the outer stringer may be formed on the same set of beams after the inner stringer has become rigid.
115	Universal work holders for assembling curved laminated units	US32530973	1973-01-22	US3879026A	1975-04-22	LAPPIN JR JAMES B
The invention includes a universal work holder or jig for use in making curved supports and railings and the like from a plurality of associated laminas, the supports so made and the method of making the same. In the preferred configuration, each support will be in the form of a helix and its principal use at present is in a so-called flying spiral stairway. Pairs of approximately dimensioned helical supporting units may be used to carry the individual stair treads and other appropriately dimensioned helical units may be used with the stairs as inner and outer handrails carried by balusters mounted on the tread supporting units. The invention however is not limited to the manufacture of elements to be used in spiral stairways.

120	Round bar	JP2008156642	2008-06-16	JP2009299383A	2009-12-24	KAWAMURA HIROHISA
<P>PROBLEM TO BE SOLVED: To provide a round bar which is high in strength against a bending load and small in deflection. <P>SOLUTION: The round bar A is formed by cutting a peripheral surface into a round bar, and made of laminated wood B obtained by alternately laminating veneers 1 different in density on each other. Since the laminated wood B obtained by alternately laminating the veneers 1 different in density on each other, is employed, the round bar can reduce the deflection by increasing the rigidity thereof by the veneers 1a high in density, and can improve the strength by enhancing the flexibility and stiffness by the veneers 1b low in density. Thus the round bar A high in strength against application of a bending load and small in deflection, can be obtained. <P>COPYRIGHT: (C)2010,JPO&INPIT
