Abstract
An aluminum banister includes a first run element, which acts as the bottom rail of the banister, defining two sets of apertures spatially disposed therealong, the first of said set being a first family of spatially disposed apertures interspaced between a second family of spatially disposed apertures, the second family being of larger cross-sectional area than the first so as to allow posts to extend therethrough which are in larger cross section than balusters which extend from the first family of apertures. There is an upper run or top rail which has an upper portion of any configuration but a lower bottom section that, in cross section, defines two longitudinally oriented races, the wider outer race being a post accommodating race and the inner race being deeper and narrower mating with balusters. The balusters and posts are welded to each run element in order to fabricate the railing. In its preferred embodiment, the banister is composed of extruded aluminum sections.
Description
- 212~487 -A BANISTER AND METHOD OF MAKING THE SAME
This invention relates to a method of making balustrades or banisters, for balconies, staircases and the like.
In particular, it relates to a simplified method of fabricating the lower and upper rail members from an extruded length of stock, whether aluminum or other appropriate metal so as to provide apertures accommodating a plurality of balusters extending between the upper and lower rail members.
Generally, the upper rail member is the hand rail portion of the banister.
Prior Art In U.S. Patent No. 3,973,756 issued 10 August, 1976 to Renee Lauzier entitled ~TRTNG ~ND METHOD OF AssT~RT.y, there is disclosed a railing device with a plurality of balusters engaging apertures in upper and lower rail elements wherein the balusters are profiled with notches on the sides so that they "lock-in" to each other. This requires unnecessary fabricating steps for the upper and lower portions of each baluster.
Similarly, in U.S. Patent No. 3,955,799, the same inventor discloses a ~Ol~llv~ ~ATT.TNG DEVICE having the same deficiencies but also requiring that the lower rail element has an under coping dependently and attached thereto.
8ASTIA, in U.S. Patent No. 3,202,401 issued 24 August, 1965 discloses a BALUSTRADE where the balusters are fixed to the upper and lower rail member by a clasp which he calls an ear.
THE INVENTION
I have conceived of a novel banister and simple method of making that banister having an upper lateral rail member, generally formed in the shape of a "U", and in a similarly shaped lower rail member and each stamped by way of a stamping machine with apertures to accommodate, balusters of a given cross-sectional area and a larger aperture at spatially disposed intervals through which extends a post the bottom of which extends into a foot or base support for the banister.
2128~87 In that respect, an aluminum banister includes a first run element, which acts as the bottom rail of the banister, defining two sets of apertures spatially disposed therealong, the first of said set being a first family of spatially disposed apertures interspaced between a second family of spatially disposed apertures, the second family being of larger cross-sectional area than the first so as to allow posts to extend therethrough which are in larger cross section than balusters which extend from the first family of apertures. There is an upper run or top rail which has an upper portion of any configuration but a lower bottom section that, in cross section, defines two longitudinally oriented races, the wider outer race being a post accommodating race and the inner race being deeper and narrower mating with balusters. The balusters and posts are welded to each run element in order to fabricate the railing. In its preferred embodiment, the banister is composed of extruded aluminum sections.
The invention therefore contemplates a banister comprising a first run element defining a plurality of apertures including a first family of spatially disposed apertures and a second family of spatially disposed adjacent apertures of pre-determined number thereof, periodically interceding next adjacent aperture of the first family apertures; a second run element defining an upper portion and a bottom section, the bottom section in cross section defining two longitudinally oriented races, a wider outer post accommodating race, and an inner, deeper and narrower baluster accommodating race; a plurality of balusters extending between the first family and second run elements and positioned into corresponding registered apertures of the first family in the first run and into the baluster race of said second run; post elements extending between the first and second run elements and positioned into corresponding registered apertures of the second family in the first run and into the baluster race of said second run; and means securing the balusters and posts to each of the run elements.
The invention will now be described by way of example 2128 i87 -and in reference to the accompanying drawings in which:
Figure 1 is a perspective view of a balustrade according to the invention, in situ;
Figure 2 is illustrative of the stamping step for upper and lower rail members;
Figure 2A is a perspective view of a portion of a stamped rail element, according to the invention;
Figure 3 is a side assembly view showing the assemblage of the components of a balustrade, according to the invention;
Figure 4 is a partial sectional view of the welding step;
Figure 5 is a section along V-V of Figure 1.
Referring to Figure 1, a banister for balustrade (10) has a first run element as a lower upright U-shaped base rail member (11) and a second run element as an upper handrail member (12), shown in phantom, which may have any outer profile, for instance, semi-circular, rectangular, elliptical or the like as may be desired for aesthetic purposes, as will be described hereafter as it relates more particularly to the cross-sectional Figure 5.
Between the upper and lower rails (11,12) are a plurality of vertical balusters (13), or pickets, arranged as sub-members of the first family, between posts (15) which extend from the upper rail element (12) through the lower rail element (11) to terminate at an anchoring plate (16) providing aperture means, not clearly shown, to anchor the plate (16) onto a balcony floor (17), as by lag bolts. The rail members (11) and (12) are composed of extruded stock, preferably aluminum and the like.
Now referring to Figure 2, the lower rail (11) may be stamped with a plurality of apertures, as shown in Figures 2 and 2A. The stamping machine (20) stamps two different sizes of apertures, a family of post accommodating larger apertures (25) and a second family of baluster accommodating smaller apertures (23) there being a sub-family of the smaller baluster apertures (23) spatially disposed between each of the post apertures (25), as more clearly seen in these 2 1 ~ 7 -figures.
From an extruded length of post stock, the posts (25) are cut to a pre-determined length; and, in a similar fashion the balusters (13).
Referring to Figures 3 and 4, prior to the post members (25) and a family of balusters (13) are positioned into the bottom portion of the upper rail element (12), as shown, the balusters (13) and post member (25) are inserted into the bottom rail element (11), as shown buy the arrows in Figure 3, which require the bottom rail element (11) to be slid past over each post (15), first, and then to have each of the balusters (13) register into their respective apertures (23) into the phantom position, shown in Figure 3. There, the balusters 913) or posts (15) are respectively welded, as shown in the cross-sectional Figure 4, with a spot weld which is generally indicated as (30) in that figure.
Having assembled the lower rail (11) to posts (15) and balusters (13), the upper element or handrail (12) is assembled. It has the profile, however, as shown in the cross-sectional Figure 5 and consists, in cross section, of an upper convex surface (41) which at opposite ends descends vertically into forward and rear side margins (42,43), the lower end of which transcends into inward sloping surfaces, respectively (44) and (45) into a bottom section generally shown as (46) and consisting of an outer channel (47) defining an inner central channel (48), the width of the channels (47) and (48) respectively being for accommodating the posts (15) and balusters (13) so that a post nests in the channel (47) and the balusters nest in the deeper central narrow channel (48). They are respectively welded to the margins of these channels buy welds (30), as shown. The rail is now complete and ready for installation, as shown in Figure 1.
It will be obvious to those skilled in the art that the length of the lower and upper rail elements (11,12) are adjusted to accommodate the width of the balcony, as seen in Figure 1, and that the number of posts (15) required will depend upon the running length of the banister (10).
212~487 It should be understood that the only critical cross-sectional configuration of the upper rail (12) is the lower or bottom section (46) which must consist of the compound channels (47) and (48), the outer channel (47) being wider to accommodate the posts (15), and the inner channel (48) narrower and deeper than outer channel (47) to accommodate the balusters.
When this type of cross-sectional configured bottom section (46) is employed, no stamping is required and the posts (15) and baluster (13) can be just welded into their respective channels (47,48) so as to stabilize the banister whereupon it is complete and now ready for installation. The bannister (10) is thus complete. It is irrelevant what the cross-sectional configuration above the bottom section (46) is used since that could be oval, square, elliptic or any satisfactorily configured upper portion.
This invention relates to a method of making balustrades or banisters, for balconies, staircases and the like.
In particular, it relates to a simplified method of fabricating the lower and upper rail members from an extruded length of stock, whether aluminum or other appropriate metal so as to provide apertures accommodating a plurality of balusters extending between the upper and lower rail members.
Generally, the upper rail member is the hand rail portion of the banister.
