US 5,101,608 A · Adjustable brick support ring

Abstract

An adjustable brick support ring (10) formed from a plurality of arcuate ring segments (16, 18) that are pivotally connected to each other in endwise fashion. Each ring segment includes a mating end (40) that is received between two connecting plates (36) that are secured on either side of an engaging end (38) of an adjacent ring segment and project therefrom. A pivot pin (56) is installed through aligned holes in the connecting plates and the overlapped mating end of the ring segment to enable adjacent segments to pivot with respect to each other for adjustment of the size of the arcuate ring. A locking pin (62) is inserted through a selected one of a sequence of locking holes (60) formed in the locking plate at a point radially inwards from the pivot pin, to pass through aligned locking holes (58) formed in the overlapped mating end of the ring segment to prevent rotation of the segments with respect to each other from an adjusted size. The ring is mounted on a slide rail assembly (72) to slide along the length of an adjustable scaffold (12).

Dependent claims

An adjustable ring for supporting bricks during overhead placement in an arcuate structure, comprising:

a plurality of adjacent ring segments forming, a generally arcuate ring having first and second ends;
adjustment means for adjusting the curvature of the ring;
and
securement means integral with the ring for securing the ring in an adjusted configuration and for rigidly maintaining the ring in the adjusted configuration so that the ring remains rigid when supported at only the first and second ends of the ring, and to permit unobstructed passage under the ring, the adjustment means comprises pivot means for pivotally connecting the ring segments in an endwise sequence to form the ring, the ring segments being pivotable with respect to each other to adjust the curvature of the ring;
and the securement means comprises a plurality of connecting members, each connecting member being selectively securable to two adjacent, pivotally connected ring segments to prevent the pivoting of the two adjacent, pivotally connected segments from an adjusted configuration.

2 more elements

An adjustable ring having a generally arcuate ring configuration and mountable on a scaffold for supporting bricks during overhead placement in arcuate structures of differing sizes, comprising:

a plurality of arcuate segments pivotally connected to each other in endwise fashion, the segments being pivotable with respect to each other to adjust the size of the ring;
and
locking means included on the segments for selectively locking the segments to each other, independently of a scaffold, to prevent pivoting of the segments, thereby imparting rigidity to the size-adjusted ring and permitting unobstructed passage under the ring.
