Definitions
- ABSTRACT A tube-type spindle for use with ornamental metal railings that is characterized by a unique flattening procedure utilized to make the ends of said tubing readily deformable when associated with the usual parallel top and bottom railings of a metal railing section. This controlled deformability allows the same railing to adjust for slopes required of stair railings.
- the flattened arrangement includes a first step of crimping on a transverse angle, followed by flattening so as to achieve a laminated structure having a width equal to the width of the tubing.
- Adjustable pitch railings of the type described in the aforementioned patent are desirable because of the fact that they facilitate do it yourself installations by the homeowner, with a minimum number of tools being required for such installations, and with the pitch of the railing being adjustable so as to accommodate the railing to varying degrees of slopes.
- the spindle portions to the railing sections are comprised of flat strips of metal that have been twisted into a spiral configuration for aesthetic purposes.
- a natural tab is provided at each end for the purpose of connecting the spindle with the top and bottom railings, respectively, and this tab which extends transversely is readily deformable for varying the pitch during installation.
- the thin wall portions of the same preclude welding or otherwise attaching the units without considerable destruction of the same thus destroying the aesthetic appearance
- a pocket or weakening hole will be in effect built in to facilitate the creation of a hinge point aroundwhich a tubing can be deformed readily for pitching purposes. This built-in feature aids automatic assembly with resultant production efficiencies.
- FIG. 1 is a perspective view illustrating the improved railing section installed in position.
- FIGS. 2, 3 and 4 are similar perspective views show ing:
- FIG. 5 is a partial perspective view showing the spindle in its pitched condition.
- the railing section generally designated by the numeral 10
- the railing section includes spaced newel posts 11 and 12 to which are secured upper and lower railing sections 13 and 14, with adapter units 15,15 serving to permit angular variation between the railing sections and the newel posts for pitch adjustment purposes and with adapters of the type set forth in Kusel et al. US. Pat. No. 3,343,81 1 being utilizable for this purpose.
- a plurality of spindles 20,20 interconnect the top and bottom railings in a manner to be described so as to always remain parallel with the newel posts 11 and 12, regardless of the pitch achieved. It should also be noted that while newel posts 11 and 12 are illustrated that one or both could be replaced by any supporting surface such as a wall. I
- FIGS. 2, 3 and 4 With reference to the spindles 20,20, the same are shown in FIGS. 2, 3 and 4, and being of laminated durable construction with a generally square cross-sectional profile being shown in the embodiment illustrated.
- the end portion is indicated generally by the numeral 21, and this portion includes, as illustrated, a top surface 22, bottom surface 23, and opposed side surfaces 24 and 25.
- the end 21 is next placed in a crimping tool that effectuates deformation of all four surfaces just described, with the surfaces 24 and 25 being crimped into the V-shaped configuration so as to define bottom apex lines 24a (not shown) and 254.
- the apex 24a and the apex 25a converge towards each other at the extreme outboard portion of end 21, with the apex lines of the V-shaped grooves being closest together at the end and then tapering apart to a point of junction with the uncrimped sidewall as best shown in FIG. 3. 1
- the opposed edges 22a, 22b, and 23a and 24a will be rounded towards each other as a result of this crimping action.
- force is applied to the opposed surfaces 22 and 23 to force the same to the position of FIG. 4, where the V-shaped sidewall portions are laminated between the upper surfaces of 23 and 24, respectively.
- a railing spindle comprising;
- said deformable tab having the width equal to the width of said body.
- the railing spindle of claim I further characterized by the fact that said deformable tab is formed by first creasing opposed sides inwardly at a transverse angle and towards a point of convergence adjacent the outer most portion of said longitudinal end; then collapsing said remaining sides toward each other under pressure whereby said creased portions are sandwiched between said remaining sides to form said deformable tab and a hinge line interconnecting said tab to said body.
- top and bottom railing sections having rectangular slots provided in the face thereof, with said slots facing each other in aligned relationship;
- adjustable connecting means securing said top and bottom railings with respect to said support surfaces for angularly adjustable relationship therewith;
- a plurality of spindles having a generally rectangular cross section, each being'hollow in nature and having a substantially flat deformed tab of laminated construction provided at the opposed ends thereof and connected to said spindles by a hinge line, with said tabs being insertable in said openings whereby a deformable railing section is provided.
