Claim 2

A vertically extending structure comprising first and second spaced wooden support members, an elongated member extending between and supported by said first and second wooden support members, said elongated member having at least one end configured to penetrate its wooden support member, each of said wooden support members in axial alignment with said elongated member, said transverse openings each including an inwardly facing portion of a size and shape to matingly receive and to envelop in a supporting fashion one end of said elongated member, a central bolt body receiving portion having a transverse dimension less than that of said inwardly facing portion, and an outer bolt head receiving portion having a greater transverse diameter than said central bolt body receiving portion and bolt means extending through said transverse opening having a threaded end threadably engaged with internal thread means in the end of said elongated member so that tightening of said bolt means pulls said one end of said elongated member into the wood to penetrate the wood of said wooden support member at the innermost extend of said inwardly facing portion of said transverse opening to tend to prevent the removal of said elongated member from said inwardly facing portions if said bolt means is removed.

Claim 3

The invention of claim 1 wherein said elongated member is a metal pipe.

Claim 4

The invention of claim 1 wherein said elongated member is a metal pipe and wherein said bolt head receiving portion is of sufficient depth to fully enclose the head of said bolt within the peripheral confines of said wooden support member.

Claim 5

The invention of claim 1 wherein said bolt head receiving portion is of sufficient depth to fully enclose the bolt head of said bolt within the peripheral confines of said wooden support member.

Claim 6

The invention of claim 1 wherein said elongated member is a metal pipe extending in a horizontal manner and having a friction enhancing outer coating.

Claim 7

The invention of claim 1 wherein said elongated member is a hollow metal pipe and said internal thread means is provided in plug members spaced inwardly in said pipe from the said one end thereof.

Claim 8

The invention of claim 6 wherein said metal pipe is of cylindrical configuration.

Claim 9

The invention of claim 1 wherein a plurality of said elongated members are mounted between said wooden support members with each of said elongated members comprising a metal tube.

Claim 10

The invention of claim 8 wherein said wooden support members comprise vertical posts and said metal tubes are horizontally oriented.

Claim 11

A vertically extending structure comprising first and second spaced wooden support members, an elongated metal tube extending between and supported by said first and second wooden support members, said elongated metal member having at least one end of a configuration to penetrate its wooden support member, each of said wooden support members including a transverse opening extending through the wooden support members in axial alignment with said elongated member, said transverse openings each including an inwardly facing portion of a size and shape to matingly receive and to envelop in a supporting fashion one end of said elongated member and a central bolt body receiving portion adjacent said inwardly facing portion having a transverse dimension less than that of said inwardly facing portion, and bolt means extending through said transverse opening having a threaded end threadably engaged with internal thread means in the end of said elongated metal tube member so that tightening of said bolt means pulls said one end of said elongated member into the wood to penetrate the wood of said wooden support member at the innermost extent of said inwardly facing portion of said transverse opening to tend to prevent the removal of said elongated member from said inwardly facing portions if said bolt means is removed.

Claim 12

A vertically extending structure comprising first and second spaced wooden support members, an elongated metal tube extending between and supported by said first and second wooden support members, said elongated metal member having at least one end of a configuration to penetrate its wooden support member, each of said wooden support members including a transverse opening extending through the wooden support members in axial alignment with said elongated member, said transverse openings each including an inwardly facing portion of a size and shape to matingly receive and to envelop in a supporting fashion one end of said elongated member and a central bolt body receiving portion adjacent said inwardly facing portion having a transverse dimension less than that of said inwardly facing portion, and bolt means extending through said transverse opening having a threaded end threadably engaged with internal thread means in the end of said elongated metal tube member so that tightening of said bolt means pulls said one end of said elongated member into the wood to penetrate the wood of said wooden support member at the innermost extent of said inwardly facing portion of said transverse opening to tend to prevent the removal of said elongated member from said inwardly facing portions if said bolt means is removed.

Claim 13

The invention of claim 10 wherein said elongated metal tube is of a cylindrical configuration and a thickness selected to deform its said one end to prevent turning of the elongated metal tube in its wooden support member upon the tightening of said bolt means.
