UNIVERSAL RAILING SYSTEM FOR LEVEL OR INCLINED APPLICATIONS

Abstract

A universal railing system for level or inclined applications which includes spaced parallel upright rod balusters extending between top and bottom railings. The upper and lower ends of the rod balusters have bent rod terminal ends which are received through respective apertures of upper and lower channels which are secured respectively to the upper and lower rails whereby the baluster rod terminal ends may rotate within the channels in order to adapt the railing system from a level application to an inclined application.

[0010] Other objects and advantages appear hereinafter in the following description and claims. The accompanying drawings show, for the purpose the exemplification, without limiting the scope of the invention or claims, certain practical embodiments of the present invention wherein:

[0011] FIG. 1 is a view in front elevation of the universal railing system of the present invention with the spaced parallel upper and lower rails illustrated in mid vertical cross section;

[0012] FIG. 2 is a view in front elevation of the universal railing system shown in FIG. 1, but adjusted for an inclined application; and

[0013] FIG. 3 is a view in front elevation of the universal railing system illustrated in FIGS. 1 and 2 with modifications disclosed therein to better illustrate the adaptability of the railing system from a level to an inclined application.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Referring to the drawings, the universal railing system 10 may be selectively used for level applications as indicated in FIG. 1 or in inclined applications, such as for stairs, as illustrated in FIG. 2. Spaced parallel upper rail 11 and lower rail 12 each have top sides 13 and 14, and bottom sides 15 and 16 respectively, and are provided with spaced parallel upright balusters 17 between rails 11 and 12.

[0015] Spaced parallel upright balusters 17 each consist of a rod of predetermined diameter D having upper and lower bent rod terminal ends 18 which extend for a predetermined distance in the general direction of extension of their adjacent rails 11 and 12. The rod balusters 17 may be made of any suitable material, such as aluminum or stainless steel.

[0016] Upper and lower elongate channels 20 and 21 respectively extend with and are secured to the upper and lower rails 11 and 12 with screws as indicated. Each channel 20 and 22 is provided with an open side 22 which is respectively secured against the bottom side 15 of upper rail 11 and the top side 14 of lower rail 12, thereby providing an enclosed elongate channel passage 23 in said channels 20 and 21.

[0017] Spaced apertures 25 in channels 20 and 21 receive the bent rod terminal ends 18 therethrough with the bent rod terminal ends 18 received in the channel passages 23 for retention in the channels. The diameter of the spaced apertures 25 is dimensioned in relation to the diameter D of the bent rod terminal ends 18 at a ratio of 1.25 to 1 with a plus or minus tolerance of 15%. If this ratio is outside of the permitted tolerances, for example the apertures 25 are too large, this will permit the rod terminal ends 18 to fall out upon rotation, and if the apertures 25 are too small, the baluster rod terminal ends 18 cannot rotate as required in order to adapt from a level to an inclined application.

[0018] The diameter of apertures 25 in relation to the thickness T of the apertures are provided at a ratio of 1 to 5 with a plus or minus tolerance of 15%. As the thickness of apertures 25 increases, the apertures will need to accordingly increase in diameter. In addition, the rod diameter will need to be adjusted if the tolerances are exceeded as the baluster rod terminal ends 18 will fall out of the apertures 25 at one extreme and at the opposite extreme they cannot rotate within the apertures 25 as illustrated by the dashed outlines in FIG. 3.

[0019] The length of the terminal rod ends 18 in relation to the depth d of channel passages 23 is set at a ratio of 1.714 to 1 with a plus or minus tolerance of 15%. If these tolerances are exceeded, the rod terminal ends 18 will in one extreme not be able to hang on and will fall out of apertures 25, and in the other extreme will exceed the depths of channels 23 to such an extent that the rod balusters cannot be adequately rotated for inclined applications which generally require an angle of inclination of between 35 to 40.

[0020] The universal railing system 10 further includes elastomeric damper liners 28 closing off the open sides 22 of channels 20 and 21. Elastomeric damper liners 28 prevent rod balusters 17 from rattling within their respective channels 20 and 21.

[0021] It will be noted that bent rod terminal ends 18 are bent to a hard right angle, as opposed to a curved or eased right angle. While slight differences in angle may be tolerated, nevertheless the hard bend of the angle is desired in order that the baluster rod terminal ends 18 can properly hinge within their respective apertures 25.
