Claim 4

A handrail assembly according to claim 2, the slotted portions in said channel portion extending in a lengthwise direction along the sides of said channel for the entire length of said rail, and said pivotal connecting means including a longitudinally extending strip interconnecting the ends of said balusters in predetermined spaced relation to one another.

Claim 5

A handrail assembly according to claim 1, each of said balusters provided with a rounded end portion at one end thereof disposed in contiguous relation to the inner closed end of said channel portion.

Claim 6

A handrail assembly according to claim 1, the connected ends of said balusters being angularly relieved in one direction to permit pivotal movement of said balusters within said channel in one direction only lengthwise of said rail.

Claim 7

A handrail assembly according to claim 1, each said fastener means including a shim interpositioned behind the slotted portion of each said connecting end portion.

Claim 8

An adjustable, prefabricated handrail assembly comprising: a pair of spaced upstanding newels; upper and lower rails each having a channel portion extending for its substantial length with open ends of said channels disposed in facing relation to one another, each said channel being of generally U-shaped cross-sectional configuration and provided with slotted portions extending in a lengthwise direction along opposite sides of each said channel for the substantial length of said rails; a plurality of balusters disposed in spaced relation to one another along the length of said rails; means pivotally connecting the opposite ends of said balusters in concealed relation within said slotted portions of said channels for pivotal movement of said balusters in a direction lengthwise of said rails, said pivotal connecting means including longitudinally extending flat strips disposed parallel to said opposite sides of said channel, each said strip being of a width corresponding to width of an associated one of said slotted portions and inserted into said associated slotted portion, said ends of said balusters pivotally connected to said strips in predetermined spaced relation to one another; and fastener means interconnecting the end of each rail to one of said newels such that said balusters extend vertically in spaced parallel relation to one another irrespective of the pitch of said rails.

Claim 9

An adjustable, prefabricated handrail assembly comprising: a pair of spaced upstanding newels; upper and lower rails each having a channel portion extending for its substantial length with open ends of said channels disposed in facing relation to one another, each said channel being of generally U-shaped cross-sectional configuration and provided with slotted portions extending in a lengthwise direction along opposite sides of each said channel for the substantial length of said rails; a plurality of balusters disposed in spaced relation to one another along the length of said rails; means pivotally connecting the opposite ends of said balusters in concealed relation within said slotted portions of said channels for pivotal movement of said balusters in a direction lengthwise of said rails, said pivotal connecting means including longitudinally extending flat strips disposed parallel to said opposite sides of said channel, each said strip being of a width corresponding to width of an associated one of said slotted portions and inserted into said associated slotted portion, said ends of said balusters pivotally connected to said strips in predetermined spaced relation to one another; and fastener means interconnecting the end of each rail to one of said newels such that said balusters extend vertically in spaced parallel relation to one another irrespective of the pitch of said rails.

Claim 10

A handrail assembly according to claim 7, each of said balusters provided with rounded end portions at opposite ends thereof disposed in contiguous relation to the closed ends of said channels.

Claim 11

A handrail assembly according to claim 7, opposite ends of each of said balusters being angularly relieved in one direction to permit pivotal movement of said balusters within said channels in one direction only lengthwise of said rails.

Claim 12

A handrail assembly according to claim 7, said fastener means defined by a bracket affixed to the closed end of said channel, each said bracket including a connecting end portion having an externally curved surface engageable with the side surface of an end post, and a male connector extending through an open slotted portion in each said connecting end portion interconnecting said bracket to said end post.

Claim 13

A handrail assembly according to claim 10, each said fastener means including a shim positioned behind the slotted portion of each said connecting end portion.

Claim 14

An adjustable prefabricated handrail assembly according to claim 7, each of said slotted portions provided with closely spaced ribs extending longitudinally therethrough with intervening grooves therebetween and a bonding agent in said grooves to adhesively secure said flat strips within said slotted portions.

Claim 15

In a handrail assembly wherein a rail member includes a channel portion extending lengthwise of said rail and an upstanding end support is disposed at least at one end of said rail, the improvement comprising a fastener interconnecting an end of said rail to said end support, said fastener defined by a bracket affixed within said channel portion, said bracket including a slotted connecting end portion of generally convex configuration with the convex surface of said connecting end portion engageable with a side surface of said end support, and a male connector extending through the slotted portion in said connecting end portion for connection to said end support.

Claim 16

In a handrail assembly wherein a rail member includes a channel portion extending lengthwise of said rail and an upstanding end support is disposed at least at one end of said rail, the improvement comprising a fastener interconnecting an end of said rail to said end support, said fastener defined by a bracket affixed within said channel portion, said bracket including a slotted connecting end portion of generally convex configuration with the convex surface of said connecting end portion engageable with a side surface of said end support, and a male connector extending through the slotted portion in said connecting end portion for connection to said end support.

Claim 17

In a handrail assembly according to claim 13, said fastener including a shim of generally semi-cylindrical configuration adaptable for insertion in said connecting end portion behind said slotted portion, said male connector element being insertable through an opening in said shim aligned with said slotted portion.
