Abstract
Abstract A fence kit for constructing a fence having upright posts, rails extending between the adjacent posts, and coupling means connecting the rail ends to the adjacent posts in a manner which permits assembly of the kit into a fence without welding or special tooling. The coupling means for each fence rail comprise collars slidable on the adjacent fence posts, means such as a socket on one collar for slidably receiving the adjacent rail end in its endwise direction, and a radially projecting lug on the other collar to be coaxially aligned with the adjacent rail end and a sleeve slidable on the lug and rail to and from a position wherein the sleeve bridges the lug and rail, whereby the fence may be constructed by first securing the fence posts in their upright positions and then installing the rails between the posts.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
129 words
A fence comprising: a plurality of upright posts arranged in a row, a rail extending between each pair of adjacent posts and having a length less than the spacing between the respective posts, first coupling means connecting one end of each rail to the adjacent post comprising a collar slidable on the respective post, and a first coupling sleeve on said collar slidably receiving said one rail end in its endwise direction, and second coupling means connecting the other end of each rail to the adjacent post comprising a collar slidable on the respective post, a radially projecting lug on the latter collar coaxially aligned with said other rail end, and a second coupling sleeve slidable on and disposed in bridging relation to said lug and latter rail end.
Claim 2
Dependent Claim
129 words
A fence comprising: a plurality of upright posts arranged in a row, a rail extending between each pair of adjacent posts and having a length less than the spacing between the respective posts, first coupling means connecting one end of each rail to the adjacent post comprising a collar slidable on the respective post, and a first coupling sleeve on said collar slidably receiving said one rail end in its endwise direction, and second coupling means connecting the other end of each rail to the adjacent post comprising a collar slidable on the respective post, a radially projecting lug on the latter collar coaxially aligned with said other rail end, and a second coupling sleeve slidable on and disposed in bridging relation to said lug and latter rail end.
Claim 3
Dependent Claim
45 words
A fence according to claim 1 wherein: each first coupling means comprises means securing the respective rail end in the respective coupling sleeve, and each second coupling means comprises means securing the respective coupling sleeve in its bridging position on the respective rail and lug.
Claim 4
Dependent Claim
13 words
A fence according to claim 2 wherein: said securing means comprise threaded fasteners.
Claim 5
Dependent Claim
42 words
A fence according to claim 1 wherein: said lug of each second coupling means is separable from its respective collar, and each second coupling means comprises a screw extending axially through the respective lug for securing the latter to its respective collar.
Claim 6
Dependent Claim
35 words
A fence according to claim 1 wherein: said rail end receiving means of each first coupling means comprises a tubular socket member permanently joined to the respective collar and slidably receiving the respective rail end.
Claim 7
Dependent Claim
45 words
A fence according to claim 1 wherein: said rail end receiving means of each first coupling means comprises a radially projecting lug on the respective collar, and the respective first coupling sleeve is slidable on and bridges said latter lug and the respective rail end.
Claim 8
Dependent Claim
44 words
A fence according to claim 1 wherein: at least one of said posts is a line post situated between two adjacent rails, and the coupling means connecting each line post and its two adjacent rails comprise a common collar slidable on the line post.
Claim 9
Dependent Claim
41 words
A fence according to claim 7 wherein: each line post collar includes the rail end receiving sleeve of the first coupling means for one adjacent rail and the radially projecting lug of the second coupling means for the other adjacent rail.
Claim 10
Dependent Claim
31 words
A fence according to claim 8 wherein: said first coupling sleeve and lug on each line post collar are coaxially aligned and located at diametrically opposite sides of the respective collar.
Claim 11
Dependent Claim
42 words
A fence according to claim 8 wherein: said first coupling sleeve and lug on each line post collar are located in a common transverse plane of the collar axis and spaced circumferentially about the collar by an angle of other than 180°.
Claim 12
Dependent Claim
135 words
Post-rail coupling means for a fence kit of the character described including fence posts to be secured in upright positions with the posts arranged in a row and rails for extension between the adjacent posts, comprising: a collar to be slidably positioned on a fence post, a radially projecting sleeve on said collar for slidably receiving one end of one adjacent rail, a radially projecting lug on said collar circumferentially spaced about the collar from said sleeve to be coaxially aligned with one end of the other adjacent rail, and a second sleeve slidable on said lug and movable to a position wherein one end of said sleeve seats against said collar and the opposite end of said sleeve extends axially beyond the lug for slidably receiving said one end of said other adjacent rail.
Claim 13
Dependent Claim
135 words
Post-rail coupling means for a fence kit of the character described including fence posts to be secured in upright positions with the posts arranged in a row and rails for extension between the adjacent posts, comprising: a collar to be slidably positioned on a fence post, a radially projecting sleeve on said collar for slidably receiving one end of one adjacent rail, a radially projecting lug on said collar circumferentially spaced about the collar from said sleeve to be coaxially aligned with one end of the other adjacent rail, and a second sleeve slidable on said lug and movable to a position wherein one end of said sleeve seats against said collar and the opposite end of said sleeve extends axially beyond the lug for slidably receiving said one end of said other adjacent rail.
Claim 14
Dependent Claim
29 words
Coupling means according to claim 11 wherein: said lug is separable from said collar, and a screw extending axially through said lug for securing the latter to said collar.
