Mankin, Akron, Ohio, assignors t Locke Manufacturing Company, Lodi, Ohio, a corporation of Ohio Filed Mar. 10, 1965, Ser. No. 438,478 3 Claims. (Cl. 256-22) This invention relates to the art of adjustable wrought iron railing, and in particular has reference to an improved type of adjustable railing section having improved aesthetic properties.
The present known prior art of adjustable wrought iron railings is best illustrated by the following three patents:
(l) Kools U.S. Patent 2,715,513 (2) Berish US. Patent 2,982,521 (3) Kusel US. Patent 3,005,623
In US. Patent 2,715,513, a rigid assembly was provided that included a top and bottom rail section interconnected by spindles that were provided with weakening holes adjacent the top and bottom portions thereof, with these weakening holes serving to permit pitching of the railing section.
In US. Patent 2,982,521, a do-it-yourself type of assemby was provided wherein the spindle ends were interconnected during assembly by use of conventional fastening means.
In US. Patent 3,005,623, an improved type of adaptor bracket was provided for the do-it-yourself type of railing to facilitate greater rigidity, while simplifying assembly of the railing in question.
While all of the prior art structures above discussed have enjoyed commercial success, it is nonetheless believed that the existing state of the prior art is deficient in several respects, as follows.
First, from an appearance standpoint, the use of stock type of extruded parts has precluded attainment of the requisite aesthetic appearance normally associated with wrought iron railings of this type. Second, and from a strength standpoint, it has been found that do-it-yourself types of railings cannot achieve the degree of rigidity and strength that is normally associated with pre-assembled railings wherein a welded or brazed type or connection has been eifectuated between spindle and rail at the time of manufacture. Third, it has been found that adjustment or pitching of the welded assembly type rail is made difiicult in the event that the owner is required to perform any type of precision drilling or deforming operation to effectuate assembly.
It has been discovered that the aforementioned disadvantages can be obviated by producing a railing section of the welded type construction wherein the top rail portion that is normally gripped by the user is provided with an additional hand receiving surface that is smooth to the touch and presents an appearance similar to that of custom made wrought iron railing. The above advantage can be further enhanced by additionally providing adaptor brackets that have offsetting means that permit limited adjustment or pitching without the need for bending or deforming of the same. Finally the rigidity requirements deemed advantageous can be achieved by forming the spindles with support pockets that serve to rigidify the unit at all times, even though the same may have been pitched at the time of installation.
Production of an improved railing having the above advantages accordingly becomes the principal object of this invention, with other objects thereof becoming more apparent upon a reading of the following brief specification, considered and interpreted in the light of the accompanying drawings.
3,339,895 Patented Sept. 5, 1967 On the drawings:
FIGURE 1 is a side elevational view of the improved adjustable railing.
FIGURE 2 is a similar side elevational view but showing the railing in pitched condition.
FIGURE 3 is a perspective view of the railing and spindle sections and showing the interconnection thereof in the preferred form of the invention.
FIGURE 4 is a perspective view of the improved bracket.
Referring now to the drawings and in particular to FIGURE 1 thereof, the improved railing assembly, generally designated by the numeral 10, is shown including a top rail 11 and a bottom rail 12, with the ends of these top and bottom rails 11 and 12 being connected to upright newel posts 13 and 14 by a plurality of identical brackets 16, 16, and with spindles 15, 15, being interconnected at their opposed ends to the top and bottom rails so as to form a complete railing assembly of the type shown in FIGURES 1 and 2.
Turning next to FIGURE 3, the top rail section 11 is shown being of generally T-shaped cross section, and includes, in the preferred form of the invention, a continuous strip of stock material that is formed to include a base section 20, a leg portion 21 and a hand engaging surface 22, with the hand engaging surface 22 being contoured to form an aesthetically pleasing smooth surface that is intended to be gripped by the user. Rigidity with respect to this railing section is provided by the double web thickness of the leg portion 21, while the base 20 provides rigidity in connection with the spindle ends as will be described.
With reference to the bottom rail 12, as shown in FIG- URE 3, the same is shown as being of one piece construction and generally T-shaped in cross-section so as to include a base 25 and a leg portion 26.
Referring again to FIGURE 3 for a detailed description of the interconnecting spindles 15, 15, it will first be noted that each spindle emanates from a Hat piece of stock material 30 that is twisted to assume the spiral condition shown in FIGURES 1, 2 and 3, with the upper end 30a and the lower end 30b being disposed in parallel so as to facilitate interconnection with the top and bottom rails, as will now be described.
In this regard, each spindle end 30a and 30b is notched or cut away, as at 31, to provide an L-sh-aped support pocket defined by wall surfaces 32, 33 and 34, with the arrangement being such that the surface 32 will seat against depending bottom edge of leg 21, while surface 33 will abut the side surface of the leg 21. Preferably the surface 34 is spaced slightly with respect to the surface 20 of the top rail and the equivalent surface that is provided on the bottom railing With this arrangement being preferable so as to localize the point of fusion with respect to the ribs 35 while facilitating easier pitching due to elimination of possible interference.
Simultaneously this reduces the number of spindle rejects which would otherwise be too long because of the nominal tolerances employed.
For :the purpose of facilitating assembly, surface 33 of the spindle is shown provided with projecting ribs 35, 35, with these ribs 35, 35 serving as a localized fusion point for the welding connection of the spindle with respect to the railing section and particularly with the side surface of the leg portion 21 thereof.
Additionally, and as shown in FIGURE 3, the utilization of the support pocket 31 has the result of creating a tongue 36, on the end of the spindle with it being apparent that the width of the tongue 36 can be reduced as by use of a tapered surface .37 so as to make the 3 tongue portion more readily bendable to the position of FIGURE 2 for pitching purposes.
Turning now to FIGURE 4 for a description of the bracket 16 per se, it will first be noted that the same is a unitary plate-like member appropriately deformed to provide a post mounting portion 40 and a rail connection portion 41, with the plane of the portions 40 and 41 being at right angles to each other to facilitate connection with the rail sections, as shown at FIGURES 1 and 2. In this regard it is further to be noted that the mounting portion 41 has an edge surface 42 that is parallel to the plane of the portion 41 but is offset with respect to the surface 40a thereof so as to facilitate a limited amount of adjustment as shown in FIGURE 2 without the need for precision drilling of either rail section.
A longitudinal slot 43 and a hole 44 are provided in the portions 40 and 41 respectively for reception of the usual bolt connection, as clearly shown in FIG- URES 1 and 2.
In use or operation of the improved railing assembly, the assembly, which includes top rail 11, bottom rail 12 and the interconnected spindles will usually arrive at the construction site in the rectangular arrangement shown in FIGURE 1, with brackets 16, 16 preferably being separately packaged.
In the event that the installation is on a flat surface, such as in FIGURE 1, then and in that event, the newel posts only need be set so that the spacing therebetween corresponds to the length of the rails 11 and 12, and upon setting of the newel posts the railing may be securely attached thereto by first cutting to the required length and then placing bolts through slots 43, 43 of the various brackets 16, 16 for engagement with appropriate openings in the walls of the newel posts 13 and 14.
Upon tightening of the remaining components, the rail section is complete, as shown in FIGURE 1.
In the event that a pitched installation is required, as shown in FIGURE 2, the installer will merely place the lowerrail 12 on the ground, with the remainder of the railing being upright in a vertical plane. At this time a longitudinal pressure applied to the top rail will cause the top rail 11 to move longiudinally of the bottom rail 12, with parallelism at all times being maintained by the interconnecting spindles 15, 15. When the railing has been deformed to the approximate shape that is required, the newel posts may be set, following by mitre cutting and attachment of the formed railing as above described. In this regard, it will be noted that drawing up of the connecting bolts will cause the railing to assume its final condition of the type shown in FIGURE 2.
It is important to note in FIGURE 2 that a certain degree of latitude is permitted with respect to locating the holes in webs 21 and 26 adjacent the ends of top and bottom rails 11 and 12, since the offsetting of the surface 42 with respect to the surface 40a permits attainment of the usual pitching required without the need for precision locating and drilling.
It should also be noted with reference to the deforming operation above described that the same is readily facilitated by the fact that the tongue 36 of the spindles has a lesser resistance to transverse deformation than would the overall spindle plate 30, with such improved bending being further facilitated by the welded contact limited to the rib portions 35, 35. It should be further noted that even though deformation occurs that each spindle 15, 15 by virtue of the support pocket 31 provides support in at least three directions.
In this regard, the surfaces 32 and 34 provide two positions of support by preventing movement of rail sections 11 and 12 towards each other while the surface 33 prevents transverse shifting of the rail.
While a full and complete description of the invention has been set forth in accordance with the dictates of the patent statutes, it is to be understood that the invention is not intended to be limited to the specific embodiment herein shown.
Accordingly, modifications of the invention may be resorted to without departing from the spirit hereof or the scope of the appended claims.
