Abstract

The stanchion base disclosed replaces the usual type of base which hitherto has been bolted with a plurality of bolts to a receiving surface such as the deck of a yacht. The adoption of toe-rails on yachts provides a stronger attachment for stanchion bases but more particularly reduces the number of additional holes in the deck and enables the stanchion base to be moved outwardly towards the sheer to provide more deck space.

The adoption of toerails on yachts provides a stronger attachment for stanchion bases but more particularly reduces the number of additional holes in the deck and enables the stanchion base to be moved outwardly towards the sheer to provide more deck space.

. 2 4 32 30 FIGS FIG. 6.

STANCHION BASE This invention relates to bases for upright supports of solid or tubular construction. More specifically, the invention provides a stanchion base for stanchions used for supporting life-lines mainly used around the periphierted by a person falling against the life-line strains conventional stanchion bases leading to fracture thereof but more particularly to loosening the fastening and causing water leakage.

The stanchion base disclosed herein has particular, but not exclusive application to yacht toe-rails of the type described in Canadian Pat. No. 913,471 issued .Oct. 31, 1972, and British Pat. No. 1,347,038 issued Oct. 20, 1971, by George H. Cuthbertson and George Cassian, both patents being assigned to C. & C. Yachts Manufacturing Ltd, Port Credit, Ontario, Canada.

The stanchion base will now be described with reference to the accompanying drawings, in which:

FIG. 1 is a plan view,

FIG. 2 is a side view,

FIG. 3 is a sectional end view taken along the line 111 III in FIG. 2. FIGS. 1, 2 and 3 are approximately fullsize, and

FIG. 4 is a part sectional view, to a reduced scale, of the stanchion base assembled on a toe-rail.

FIG. 5 is a side elevation of a split pin used in the present invention.

FIG. 6 is a side elevation of a hollow tension pin used in the present invention.

Referring now to the drawings, the stanchion base 1 comprises a block of material having a vertical hole 10 for the reception of stanchion 12 which is generally of tubular form.

An open ended keyhole shaped aperture or slot 14, is adapted to slide along a toe-rail, generally indicated at 50 in FIG. 4, and to be clamped at a selected position on the toe by a pair of

counter-sunk screws

16 and 18 passing through clearance holes 20 and 22 and engaging threaded holes 24 and 26. The keyhole shaped aperture or slot 14 is defined by a substantially partcylindrical portion 28 and inner and outer surfaces 30 and 32. The axis of the part-cylindrical portion 28 is laterally displaced from and may be substantially perpendicular to the axis of the stanchion-receiving hole 10. It is to be understood that the axis of the partcylindrical portion 28 may be set non-perpendicularly relative to the axis of the stanchion hole if it is desired to accommodate a non-level mounting surface or when the stanchion is to be other than vertical. For example, the stanchion base may be used for supporting structural members of a yacht pulpit which are commonly inclined forwardly. Generally,

the angle between the rail and stanchion will notbe less than 45. An additional clearance hole 34 and threaded hole 36, disposed parallel to the

holes

20, 22, 24 and 26 received a further screw 38 or retaining device which passes through a hole 40 in the stanchion 12 for retaining the stanchion in position. Other forms of retaining devices such as split pins and hollow tension pins as shown in FIGS. 5 and 6, respectively, as well as rivets may be used.

While the preferred embodiment has been described with reference to a toe-rail having. a part-cylindrical head along the top of the vertical flange thereof, the stanchion base may have other apertures,-in lieu of the keyhole shape, to suit other toe-rail cross-sections.

Generally, the bases may be cast or machined from the solid. The bases may be formed in bronze, aluminum alloy, stainless steel or plastics.

, When applied to the yachts, the stanchion base provides an additional 2 to 3 inch usable deck space around the periphery of the deck of the yacht.

Other embodiments of the invention falling within the terms of the appended claims will occur to those skilled in the art.

b. a second open-ended hole for slidably receiving said upstanding flange, said second hole being defined by a pair of spaced apart opposed side surfaces disposed on each side of a second plane, said second plane being spaced from said first plane, said side surfaces being joined by a top surface, said top surface being disposed at a selected angle between 45 90 relative to the axis of said first hole, and,

ii. clamping means for urging said pair of spaced apart opposed side surfaces toward 'each other and into engagement with said upstanding flange when disposed therebetween, said clamping means comprising at least one screw a portion of which is slidably received in a third hole in said block disposed on one side of said second plane, the end of said screw engaging a threaded fourth hole in said blockdisposed on the other side of said second plane.

3 y 4 6. A stanchion base as in claim 5, further including said stanchion. at least one screw member passing through said block 8.
