A handrail system optimized for use-with children under 5 years of age, which includes an elongated rail and support brackets for hanging it, beneath a standard handrail, at a height of about 28 inches and within easy reach of toddlers. Shaped to fit a child's hand, the rail of generally circular transverse cross-section, defines an elongated pocket for receiving the user's thumb so that the child can grip the rail firmly. Also included is an elongated rubber insert mounted on the rail and spaced apart from the elongated pocket. The rubber insert is positioned in such a way that when the user's hand grips the rail and his thumb engages the pocket, his finger tips press against the rubber insert, reducing the child's chances of slippage. Installable by the average do-it-yourselfer, three support bracket embodiments are provided: one attachable to the standard handrail and the others to the wall.

A lighted handle includes an elongate light transmitting member that has first and second end portions. First and second support surface engageable mounting brackets carry the first and second end portions of the light transmitting member. A narrow beam light emitter is located in the first mounting bracket and has a light beam emitting end. The light beam emitting end faces the adjacent first end portion of the light transmitting member and is aimed longitudinally along the light transmitting member to make the same more visible.

A platform system comprising a platform structure having at least one modular platform unit with platform connection features on a side surface thereof to which other components can be connected, the other components including at least two of the following: another modular platform unit, a stair unit, a tower unit, a handrail unit, and a ladder unit. A stair assembly is connected to the platform structure via said connection features, the stair assembly comprising a plurality of stair units connected together to provide a number of steps equal to the sum of steps of the stair units.

Provided is a sense amplifier circuit in a semiconductor memory device in which an under-drive is applied to a switching element of a pull-down side of a sense amplifier in order to compensate for poor driving capability in the case of performing a low voltage operation. The sense amplifier circuit includes: a sense amplifier which has a pull-down element composed of an NMOS transistor and a pull-up element composed of a PMOS transistor and is formed between bit lines to perform data exchange; and a drive controller which supplies a drive voltage for the use of pull-up and pull-down operations to the sense amplifier in order to perform the data exchange, and, during a specific time period included in a time for providing the drive voltage, performs an under-drive whereby the drive voltage for the use of the pull-down operation is used so that the sense amplifier is provided with a voltage that is lower than a voltage used in the pull-down operation in a normal state.

A handrail assembly comprises an elongated railing and a plurality of brackets. The railing has two lateral channels extending along its length and a central member extending between the two lateral channels. At least one of the brackets has a base and two prongs extending away from the base. Each of the prongs engages one of the lateral channels. The engagement of the railing with the brackets forms a cavity that is defined, at least in part, by the central member, the base, and the prongs.

A decorative bar, configured to be mounted on a surface (wall or floor) of a room or building, comprises (a) an elongate rod formed of natural stone and having a substantially constant cross-sectional shape from a first end to an opposite, second end and a longitudinal groove extending along one side, and (b) an elongate metal armature or brace having a portion thereof inserted in and substantially filling the longitudinal groove in the stone rod. The metal brace has a flange or bracket at each end configured to be attached to the surface (wall or floor) of a building to affix and retain the stone rod in a mounted relationship to this surface with its longitudinal groove on a side which is not readily visible to a casual observer.

A handrail assembly includes at least one connecting unit, and at least two extension units each connected with the connecting unit. The connecting unit includes a middle tube and two connecting tubes extended from two opposite ends of the middle tube respectively. Each of the connecting tubes has a surface formed with a plurality of elongate slits. Each of the connecting tubes has a periphery formed with an annular reinforcing rib to enhance resilience and fixedness of each of the connecting tubes. Each of the extension units includes a mounting pipe mounted on a respective one of the connecting tubes. Thus, the connecting units and the extension units are detached before assembly to facilitate and reduce the cost of storage, packaging and transportation of the handrail assembly.

Synthetic laminate structures and mounting assemblies for use therewith. Multi-sectional clip structures are provided for use individually or jointly in securing synthetic trim mountings.

A grab rail with automatically activated light including: a straight longitudinal bar having a front longitudinal face and a rear longitudinal face and hollow openings at each end; two light units, each sealingly but releasably secured in one of said hollow end openings; a battery source connected with the light units and located inside the bar; at least one noise activated switching device operatively associated with said LED light units and battery source; and at least one post mount with flange, wherein an end of the post distal the flange is secured to the rear longitudinal face of the bar.

A combination crash rail and railing system provides walking-aid support along a wall and protects the wall from impact damage. The system includes a distinct handrail and crash rail components, and one or more wall-mounting brackets. The handrail and crash rail components are independently mounted along the wall on common wall-mounting brackets that are secured to the wall. The wall-mounting brackets have a universal design that allows flexibility in the choice of the types of handrail and crash rail components that can be installed. In one universal design, a wall-mounting bracket includes a base plate, which can be secured to a wall surface, and separate handrail- and crash rail-mounting flanges that are disposed at the ends of a pair of arms that extend from the base plate.

A reinforced handrail provides two to four brackets attached to wallboard in a linear manner. Two brackets are end brackets, and there may be one or more center brackets. The wallboard is supported by vertically oriented 2x4 studs at spaced intervals, and is typically covered by tile, fiberglass or other protective surface. The wallboard and 2x4 studs may be strengthened by 2x6 reinforcements which are carried between adjacent 2x4 studs. Each bracket carries a short stand-off which is oriented perpendicularly to the wallboard. The stand-offs carried by end brackets in turn carry elbows. The stand-offs carried by center brackets carry rail supports. A handrail is carried by the elbows and rail supports. Where the handrail is formed from first and second segments, a stiffener insert may be used to increase the rigidity between the segments.

A wall mounting system includes an interlocking mesh backing element mounting to a substrate, such as foam insulation. The backing element has pointed corner portions that are pushed into the substrate and retain the backing element. A wall covering layer such as drywall overlays the substrate and the mesh backing element. A fixture having has bolts, screws or other attachment members extending through the wall covering layer and the mesh backing element. The system has several backing element styles, including planar elements, inner right angle elements and outer right angle elements.
