United States Patent Ofiice 3,l?4,727 Patented Mar. 23, 1%65 3,174,727 RAILING SUPPORT BEANS Lewis M. Burt and Louis Hermann, Youngstown, Ohio,

assignors to Superior Aluminum Products, Inc, Youngstown, Ohio, a corporation of Ohio Filed Sept. 18, 1962, Ser. No. 224,377 6 Claims. Cl. 256-22) This invention relates to railings, balustrades, fences and the like and consists generally in an improved device for attaching balusters, posts and the like to railings.

The principal object of the invention is the provision of a device that may be positioned in a railing or a balustrade or similar object and pivoted to the top of a support baluster and actuated to lock said baluster to said railing.

A further object of the invention is the provision of a simple, inexpensive, easily formed device for attaching a railing or a balustrade to the end of a supporting baluster.

A still further object of the invention is the provision of a device for attaching a railing or balustrade to a balus ter and which device may be die cast, molded or otherwise inexpensively mass produced.

A still further object of the invention is the provision of a railing or balustrade having an internal cross-sectional configuration adapted to provide opposed surfaces between which a tiltable member may be positioned and wedged by mechanical action so as to act as a means attaching a supporting baluster to said railing or balustrade.

A still further object of the invention is the provision of a railing or balustrade having a cross-sectional configuration including at least three parallel spaced surfaces and a member engageable between said parallel surfaces and tiltable relative thereto and attached in pivot-a1 manner to a baluster so as to secure said baluster in said railing or balustrade.

The device for attaching a railing or balustrade to a baluster as disclosed herein comprises an improvement in the art relating to railings, balustrades, fences and the like and particularly the ornamental railings and balustrades as used in commercial constructions wherein hand rails and guard rails are positioned on the sides of stairways at the sides of balconies and on platforms to provide visual or physical obstacles or supports for the hands of persons using the stairs, balconies, etc. In the several constructions heretofore known in the art various means of securing the railings, balustrades and the like to supporting balusters have been proposed and such devices generally have been rather expensive to make, ditficult to install, and usually incapable of being installed in the railing except at predetermined intervals or locations there along.

The present invention relates to a simple and efiicient device which may be pivotally attached to the end of a baluster engaged in a railing of suitable cross sectional formation and quickly wedged into position therein by actuating a metal screw or the like to provide a tilting wedging action to the member itself. The device is therefore capable of securing the post or baluster to the railing at any location therealong and at the same time being adapted to permit the baluster to be located at any desired angle relative to the railing or vice versa.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.

The invention is illustrated in the accompanying drawing, wherein:

FIGURE 1 is a top plan view of the railing or balustrade mounting bracket.

FIGURE 2 is a side elevation thereof.

FIGURE 3 is an end elevation thereof.

FIGURE 4 is a perspective view thereof.

FIGURE 5 is a cross section of a railing or a balustrade showing a portion of a baluster and the attachment member in position securing the same together.

FIGURE 6 is a horizontal or side elevation with parts broken away and showing the attachment device in the railing as shown in FIGURE 5.

FIGURE 7 is a section of a railing and a plurality of balusters formed with the device disclosed herein.

FIGURE 8 is a section of railing wherein the rails are angularly disposed relative to horizontal and the balusters are vertically disposed and wherein the railing is formed with the device of the invention.

By referring to the drawings and FIGURE 1 in particu lar, it will be seen that in top plan view the attachment device comprises a substan ially rectangular appearing member having a pair of spaced side walls It! and 11, an elevated end wall 12 with an upstanding transverse portion 13 and the opposite end wall comprising a horizontally disposed portion 14 having a longitudinally projecting section 15 apertured vertically as at 17. The side walls 10 and 11 are also apertured transversely as at 18, 18 as may best be seen by referring to FIGURE 2 of the drawings. The side walls 10 and 11 have depending parallel rib-

like sections

19, 1% as best seen in FEGURES 2, 3 and 4 of the drawings and the portions of the side walls 16 and 11 located between the portions thereof having the

apertures

18, 18 therein and the end thereof closed by the cross member or relatively low wall section 14 are tapered downwardly thereto, the tapered sections being indicated by the

numerals

20, 20. The opposite or lower corner sections thereof which extend between the ends of the ribs 19 and the end wall 12 are also angularly disposed as indicated by the numerals 21, 21. It will thus be seen that the particular device which makes the attachment of the railing to a support baluster possible is of a configuration that may be molded of plastic, die cast of metal, or otherwise inexpensively reproduced in quantity.

By referring now to FIGURE-S 5 and 6 of the drawings the device illustrated in FIGURES l, 2, 3 and 4 and heretofore described may be seen in securing position in a railing or balustrade section and attached to la baluster. In FIGURE 5 a cross section of a railing 22 may be seen and it will be observed that the railing has depending

side sections

23, 23 from each of which inturned and upturned

flanges

24, 24 project to define a longitudinally extending slot spaced between the upturned portions of the

flanges

24, 24. The railing 22 also has a cross sectionally L-shaped depending member longitudinally thereof as generally indicated by the numeral 25 and which includes a horizontal portion spaced vertically relative to the

flanges

24, 24 heretofore referred to. It will be seen that the space between the horizontal portion of the L-shaped member 25 of the railing 22 and the

flanges

24, 24 thereof is sufiicient to receive the device heretofore described and illustrated in FIGURES 1 through 4 and that when it is positioned therein the depending

ribs

19, 19 in eifect straddle the upturned ends of the

flanges

24, 24 while the upwardly extending end 13 of the wall 12 lies closely adjacent the lower horizontal surface of the L-shaped portion of the railing 22. A metal screw S of the self-tapping variety is engaged in the opening 17 in the device and when the same is rotated so as to move the same upwardly relative thereto the point of the metal screw S will engage the bottom of the L-shaped portion 25 of the railing 22 3 as seen in FIGURES 5 and 6 and thereby tend to move this end of the device downwardly. The device itself is pivoted to the end of a baluster P by a pivot pin 26 so that the net result of the motion is to wedge for upstanding end 13 against the bottom of the member 25 The device acts as a lever positioned over a fulcrum.

Those skilled in the art will observe that the relative position of the baluster P is a matter of choiee and that the device operates to lock itself in position in the railing 22 by the tilting, Wedging action imparted by the action of the metalscrew S when the same is rotated inwardly or vertically upwardly as shown in FIGURES 5 and 6 of the drawings, By the same token the reverse rotation of the metal screw-S will permit the device to move to unlock position and the baluster P may then be moved relative to the railing.

It will thus be seen that a railing such as shown in FIG- URE 7 wherein there is an upper and lower rail and a plurality of balusters P therebetween may be formed by u'sing a plurality of the devices one on each end of the balusters P or that the railing maybe inclined at an angle as shown in FIGURE 8 of the drawings and will also be seen that any desired spacing may be arranged between the balusters P as it makes no difference to the operation of the device in attaching the same to the railing 22. It will also occur to those skilled in the art that the exterior configuration of the railing 22 may take any desirable shape and need not necessarily be limited to that shown herein which is for the purposes of illustration only. If desired, a fillet section which is a simple channel-shaped member may be inserted between the

flanges

24, 24 of the railing, between each of the balusters P, in order to 'completely'enclose the device and this is not otherwise described or illustrated herein as such has been a common practice in the metal railing industry as heretofore used to hide the screws or fastener's by which the balusters P were attached to devices 5 which in turn were bolted or otherwise attached to the railings employed.

It will thus be seen that a relatively simply and inexpensive device has been disclosed which upon being pivotally attached to a baluster and engaged in a railing or balustrade of suitable configuration particularly the cross section including the details hereinbefore noted will enable the post or baluster to be secured tightly to the railing or balustrade section and that as many of such balusters may be used as required and that any angle of baluster relative to the angle or horizontal or vertical position of the railing may also beachieved. g

It will thus be seen that the device for securing a railing to a baluster meeting the several objects of theinvention has been disclosed and having thus described our invention, what we claim is: p
