141	Wooden material, manufacturing method therefor and wooden fence	JP2004205238	2004-07-12	JP2006026944A	2006-02-02	TSUZUKI YOSHIO; TSUZUKI SOUHO
<P>PROBLEM TO BE SOLVED: To provide a wooden material having an antiseptic and vermin-proof effects and having a brown or dark-brown hue on the surface using an inexpensive material, a manufacturing method therefor and a wooden fence using the wooden material. <P>SOLUTION: The wooden material is constituted by coating or impregnating the surface thereof with a diluted asphalt emulsion or subjecting the coated or impregnated surface thereof to combustion treatment. The wooden material is manufactured by immersing a wood piece in the diluted asphalt emulsion or a diluted cationic asphalt emulsion or subjecting the surface after immersion of the wood piece to combustion treatment using a direct fire. The fence F is constituted by supporting vertical wood pieces 30 on horizontal beams 10 and constituting either one of the horizontal beams and vertical wood pieces of the above wooden material. <P>COPYRIGHT: (C)2006,JPO&NCIPI
142	Handrail bar and handrail	JP2004016064	2004-01-23	JP2005207154A	2005-08-04	TONARI KOJI
<P>PROBLEM TO BE SOLVED: To provide a ligneous handrail bar which can be fixed easily and a seeming handrail using the same. <P>SOLUTION: The handrail bar 1 is made of a laminated material formed of veneers 11 connected by the finger-joint or scarf-joint at every specified length. The veneer 11 is constituted of a high specific gravity wooden material, the fibrous direction of the veneer 11 is lined up and subjected to the lamination adhesion in the ligneous handrail bar, and the bar 1 is fixed to columns 3, 4 by use of brackets 2 to form the handrail A. <P>COPYRIGHT: (C)2005,JPO&NCIPI
143	STAIR TREAD MADE OF GLUED LAMINATED WOOD	JP2000085608	2000-03-27	JP2001271470A	2001-10-05	TANAKA HIROBUMI; OGAWA MINORU; TOJO TAKASHI
PROBLEM TO BE SOLVED: To prevent a person from losing his footing due to slippage in stairs which are diagonally installed and often have an open ceiling so that a fitting position and the lighting angle of a lighting system are restricted, and the person can hardly watch the step due to the shadow of the person himself in going up/down the stairs, thereby often losing his footing due to slip. SOLUTION: This tread is constituted of a glued laminated wood so as to easily recognize the nosing of the tread and timbers comprising a part near a nosing are constituted of the glued laminated wood material or LVL formed by laminating and sticking veneer sheets or thin plates of timbers having two types of colors or more so that the timbers constituting the part near the nosing are mutually and clearly identified. A striking difference such as a striped pattern is formed on the nosing so that even a weak-sighted person can recognize the nosing even in stairs with insufficient lighting.

145	TREAD STRUCTURE OF STAIR, AND ITS MANUFACTURE	JP30555196	1996-10-30	JPH10131448A	1998-05-19	SAKANO TAKAO
PROBLEM TO BE SOLVED: To provide a tread structural body excellent in safety in ascending/ descending a stair, excellent in execution workability, and excellent in design. SOLUTION: A tread structural body of a stair comprises a tread plate part 110, and a rise plate 120 which is continuously provided on the tread plate part 110 in an approximately orthogonal manner thereto. The tread plate part 110 and the rise plate part 120 are made of a core of the same material, a surface material 3 is attached to the surface side of the core 10, and a corner part formed of the tread plate part 110 and the rise plate part 120 is of chamfered shape. In the corner part, a plug 2 of the same material as that of the surface material 3 is embedded in the core 10 between the surface material 3 and the core 10.
146	ROTARY STAIR AND ITS EXECUTION METHOD	JP18991195	1995-07-26	JPH0941607A	1997-02-10	SHIYOUKO TOSHIHIRO; SHIYOUKO MIKIO
PROBLEM TO BE SOLVED: To execute a rotary stair in a short time or in a short period. SOLUTION: In fitting a reference side plate 44 to columns 34-36 as a supporting member of a rotary part, the vertical position relative to the columns 34, 36 of the reference side plate is set by making a lower reference position display part agree with an upper reference position display part which are respectively provided on the upper and lower positioning parts and the reference side plate 44 provided on a positioning fixed plate 51. After the positioning fixed plate 51 is fitted to a column 31 as a center supporting member, other side plates 41-43, 45-47 comprising a rotary stair and treads 1-13 are fitted.

149	BEAM FOR CURVED STAIR	JP15469291	1991-06-26	JPH0518073A	1993-01-26	TONARI KOJI
PURPOSE:To raise productivity of beams by a method in which fitting holes for step plates of beams formed by laminating plates for a curved stair are formed by machining process in flat plates, and the flat plates are curved and bonded to each other. CONSTITUTION:A beam to be attached with step plates and hand rails for curved stair is formed by laminating plates 1 through an adhesive 2. Fitting holes 4 to be fitted with step plates for the plates 1 are formed by machining process in flat plates before being curved. The flat plates are curved along a mold 6 and bonded to each other Step plates are provided between beams on both sides and attached with hand rails. The accuracy and productivity of curved stair can thus be raised.

158	HARDWOOD STAIR TREAD OVERLAY	US14156404	2014-01-15	US20140130430A1	2014-05-15	James M. McCool
A stair tread overlay and a riser overlay made from solid wood for fitting over a conventional, exposed wooden stair having a generally rounded nose like those found in most residential general construction staircases and prefabricated staircases. The tread overlay and riser overlay cover the exterior surface of a conventional wooden stair from stringer to stringer to hide a construction grade stair tread and riser below that are made from a composite material or unsalvageable hardwood to present an attractive, solid wood surface that is finishable.
159	Methods of manufacturing curved staircases and staircases produced	US800064	1991-11-27	US5163491A	1992-11-17	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.
160	Method and apparatus for forming curved handrails	US400868	1989-08-28	US4960137A	1990-10-02	Ronald W. Pott; William G. Grimm
An on-site fabrication method has been devised for compound bending of laminated wooden beam members into a handrail for curved or spiral stairways in which upstanding supports are positioned at intervals along the path of intended curvature on the stairway, the strips are assembled together in juxtaposed relation to one another and retained by leveling brackets on the support members whereby to prevent twisting of the beam members when a lateral force is applied, clamping the beam members together against each support member and permitting the beam members to be cured into a unitary rail section. In the preferred apparatus, right angle brackets are anchored to the tread portions with upstanding support members or legs disposed along the path of intended curvature, channel-shaped brackets are associated with the right angle brackets to apply pressure to the top and bottom surfaces of the beam members, and C-clamps apply a laterally directed pressure to clamp the beam members firmly against a closed end of each channel-shaped bracket and vertical leg of each right angle bracket.
