Abstract
ABSTRACT OF THE DISCLOSURE
A structure, useful as a balustrade or fence, comprising a rail attached to a plurality of pickets. The rail has first and second longitudinal members that are pressed together to form the rail. There are spaced openings formed in one longitudinal member with an open edge for each opening at an edge of the longitudinal member, Channels are formed in each side of the picket member, adjacent an end of the picket member. There are projections on the first and second members, adjacent to each opening. Each projection is received in a channel of a picket. The arrangement of channels and projections provides a rattle-free structure.
The structure can be further improved by the incorporation of a settable compound to assist in the pressing together of the first and second members.

Description
45183-g ~3~6~33 PICKET ATTACE~MENT
This invention relates to a structure, particularly a structure useful to form ~encing, balustrades and the like.
Pencing and balustrades, for example on patios and balconies, are well known. They provide a pleasing appearance. They may be of wrought iron, wood or, increasingly, aluminum. Aluminum has the great virtues of ; excellent weather resistance, ease of formation, lightness and is itself of pleasing appearance. In certain circumstances, aluminum is not coated at all but, in other circumstances, a simple clear lacquer inish is sufficient to provide a maintenance free surface.
The fencing or balustrade typically comprises a top rail secured to pickets, that is vertical members extending downwardly from the top rail and spaced at any desired intervals. The pickets may extend into a wooden or concrete ~base or the like or, more usually, are also attached to a bottom ra~11. The rails are supported on end posts which are mounted to ~a base structure~; the steps, balcony or the like ~; for which the structure provides an edge.~

' -~3~33 In aluminum struc-tures, the pickets may be attached to the rails in a variety of ways. My Uni-ted States Patent No. 4,125,249 issusS~d 14 November, 1978 shows a system in which variation of the angle of a picket to the rail is achieved. However, in many structures a permanent attachment is used. For example, the pickets may be welded to longitudinal rails. A further known system is the use of a snap-together rail comprising longitudinal sections -that can be joined together by snap-fit. There are openings formed in one of the longitudinal members to receive the pickets. A disadvantage of the system is that the pickets are a loose fit within -the rail structures, which is undesirable.
Longitudinal mem~ers of this type are used for both -top and bottom rails.
The present invention seeks to provide a simple solution to the above problem of loose piclcets and, in addition, provides an improvement for securing the longituclinal members tha-t form the rail.
Accordingly, the present invention is a rail structure ha~ing a rail attached to a plurality of pickets, the rail comprising first and second longitudinal members that are preæsed together to form the rail; a plurality of spaced openings formed in the first longitudinal member with an open edge for ea~h opening at an edge of the first longitudinal member; an opposed pair of spaced channels formed in each side of each picket adjacent an end of the picket, a first channel of each pair being closer to the end of the picket than the second channel of each pair; first projections in s , .
~3~3~
the interior of each firs-t and second longitudinal member to fit closely into the opposed first channels on a picket; second projections on each first and second longitudinal member to fit closely into ~pposed second channels on a picke-t; a pair of male members formed at a pair of side edges of the first longitudinal member; a pair of female members formed at a pair of side edges of the second longitudinal member to receive the male members of the first longitudinal member with a press fit to :Eorm the rail;
whereby pressing together of the first and second longitudinal members, with pickets located between the first and second longitudinal members in the plurality of spaced openings formed in the first longi-tudinal memberl to engage the male members of the fi.rst longitudinal memher with the female member~ of -the second longitudinal member engages the first and second projections respectively in the first and second channels with a press fit that prevents move~ent of the pickets relative to the rail.
Aspects of the invention are illustrated, merely by way of example, in the accompanying drawings, in which:
Figure 1 is a detail of a s-tructure according -to the present invention;
Figure 2 is a detail on the line Figure 1;
Figure 3 is a partial exploded view of -the structure of Figure l; and Figure 4 is a furth~r detail of the s-tructure of Figure 1.
The drawings show a structure having a top rail 10 attached to a plurality o~ pic~ets 12. In the embodiment of , ~ .
~ ~3~6~33 Figure 1, a bo-ttom rail 14 is also shown but the bottom rail is not essential. The picke-ts 12 may simply extend to the ground, into concrete or into an underlying wooden structure.
Rail 10 comprises first and second longitudinal members 16 and 18 that, as shown most clearly in Figure 2, press together to form the rail. This pressing together of the first ancl second longitudinal members 16 and 18 is achieved by the provision of a pair of male members 20 formed at edges 24 of the first longitudinal member 16.
A pair of corresponding female members 26 are formed at edges 28 of the second longitudinal member 18 to receive the male members 20 with a press fit. As is clear in Figures 2 to 4 the fence may be produced as an extrusion but the shape shown is, subject to comments made below, immaterial.
As shown most clearly in Figure 3, there is a plurality of spaced openings 30 formed in the first longitudinal member 16 with an open edge for each opening at an edge 24 of the first longitudinal member 16, that is adjacent the lower male member 20.
The pickets 12 are each formed with a pair of channels 32 on each side, adjacent an end. As shown particularly in Figures 2 and 3, there are spaced projections 34 on the firs-t longitudinal member 16 and spaced projections 36 on each ~3(:)6633 second longitudinal member 18 to be received in the channels 32 to locate -the picket 12.
Figure 2 also shows -the provision of a raised portion 37 adjacent the outer edge of each female member 26 of the second longitudinal member 18 to preven-t egress of the triangular ends of the male members 20. Serrations 38 shown in Figure 3 also facilitate contact with a settable composition received in the female members.
Thus to construct the s-tructure shown in Figure l, the longitudinal members 16 and 18 are cut -to length to extend between end posts, not shown. Pickets 12 are located in a first longitudinal member 16 with the projections 34 of the first longitudinal member engaging one pair of channels 32 in the picket 12. An appropriate settable compound, silicone, an epoxy adhesive or the like, is placed in the female members 26 and the first and second longitudinal members 16 and 18 are then pressed together with the projections 36 on the æecond longitudinal member 18 engaging the other pair of channels 32, that is opposed to those already engaged on the projections 34 of the first longitudinal member 16. Pressing together of the first and second longitudinal members 16 and 18 ensures engagement of the male and female members 20 and 26 and of the pickets on the projections. In -this way an extremely æecure and stable structures provide, also assisted by the settable compound in female members 26.
3~1 6~3 Further stability may be achieved, in extreme cases, by inser-ting self-tapping screws through the outer wall of member 16 and through the upstanding wall of member 16 carrying projection 34~ The screw is self-tapped into a hole formed in longitudinal member 18 adjacent upper projection 36. The screw is counter~sunk and may be placed at, for example, thr~e foot in-tervals. It will b~ unob-trusive.
If required the bottom rail may be attached in precisely the same way and, in constructing the structure, the lower first longitudinal members will be engaged in the same way and at the same time as the upper first longitudinal members.
The two second longitudinal members are then engaged -to complete the structure.
The present invention thus provides a structure of great simplicity yet rigidLty. The pickets are secured firmly and without rattling.
