Abstract
A railing construction in which a continuous aluminum or other metal rail member is provided with a downwardly directed slot or opening extending along the length thereof. Rail supporting posts, balusters, wall brackets or the like are receivable in said slot at any desired longitudinal spacing. Each of such supporting elements are provided with opposed sidewalls disposed in spaced relation to the sidewalls of the slot when the element is inserted therein. Wedge members are then inserted in opposite longitudinal directions in such spaces to tightly lock the rail member to the supporting element.

Taylor Attorney-Harris Zimmerman PATENTEUHUV 16 I97! SHEET 2 [1F 2 INVENTOR. ROBERT H. MURDOCK vBY ATTORNEY RAILING CONSTRUCTION BACKGROUND OF THE INVENTION In the fabrication and assembly of metal railing constructions, and more particularly in' desirable aluminum railings, numerous problems exist when the railing is required to not only extend for a straight run, but must be adaptable to rattleproof ramps, corners, wall returns, and at the same time be subject to various slopes or rakes. Aside from the connection of the rail member per se to a supporting element, most railing installations require special fabrication to accommodate each job, or a substantial amount of time is spent on the job site to effect proper installation.
In accordance with the teachings of the present invention, an extremely simple, strong and durable railing construction is provided which is substantially universal in application, which may be rapidly installed without conventional fastening means, which is and rattleproof, which is most effective against nonnal vandalism.

DESCRIPTION In broad terms, the structure of the present invention includes a continuous top rail 10, a rail supporting element 12, and wedge elements 14 for securely locking the rail to the supporting elements. Preferably all of these components are formed of aluminum.
Referring first to FIGS. 1 to 3 of the drawing, it will be seen that top rail consists of a longitudinally extending aluminum extrusion of a generally inverted U-shapedcross'sectional configuration. The rail includes a top wall 16, depending sidewalls l8 and short opposed inturned flanges 20 at the lower ends of the sidewalls. Thus, the rail defines a continuous downwardly opening slot or opening extending for the length of the rail.
The inner surface 22 of the top wall and the opposed spaced inner surfaces 24 of the sidewalls are generally disposed at right angles to each other, while the outer surfaces of such walls are preferably curved and without any sharp edges to present a more pleasing aesthetic effect.
Rail 10 may be supported at spaced locations along its length by the elements 12, which as shown in this embodiment of the invention comprise tubular posts 26 also formed of aluminum. The spacing between at least two opposed walls 28 and 30 of the post is such that the post may enter the restricted opening to the rail slot defined by the inner edges of the flanges 20, but with a minimal clearance therebetween, which thereby centers the post relative to the rail sidewalls 20. The top end of the post may thus engage surface 22 of the top wall at any longitudinal position along the rail. With the post so inserted, or in the usual situation with the rail placed over preinstalled posts, generally rectangular spaces 32 and 34 are provided between the post walls and the inner surfaces of the rail sidewalls.
To rigidly lock rail 10 to post 26, the wedges 14 are inserted in the spaces 32 and 34. The wedge 14, best illustrated in FIGS. 5 and 6 of the drawing is preferably formed as an aluminum die casting and includes a body portion 36 having a flat bottom wall 38 and a top wall 40 which is longitudinally tapered towards one end of the body which terminates in a thin edge 42. The width of the body is less than the spacing between the top of flanges 20 and top wall surface 22 thereby permitting ready insertion of the wedge with its bottom wall positioned against one of the inner sidewall surfaces 24. The maximum thickness of the wedge body is greater than the inward projection of flange 20 so that with the post positioned in the rail slot, wedges 14 may be driven between post 28 28 and 30 and their respective spaced surfaces 24 of the sidewalls. As illustrated, the wedges are driven from opposite longitudinal directions which results in an extremely tight and secure locking action between the rail and post. Preferably, the wedge is provided with a head portion 44, extending normally from bottom wall 38 for the width of the body and terminating beyond the top wall 40. This head provides easier handling and insertion of the wedge and also defines a relatively large end surface 46 which permits the use of a tool to forcibly drive the wedge into the aforesaid locking relationship. When so locked, the hidden nature of the wedges as well as its tight fit will effectively resist normal vandalism. 1
To further insure the locking action, the top and bottom walls of the wedge are provided with longitudinally extending ridges or ribs 48 which project outwardly for adistance of about 0.0l5 inch. It would be possible, but not too practical, to provide such ridges on the post or rail surfaces engaged by the wedge.
Referring to FIG. 4 of the drawing, it will be seen that the identical constructional features are present where the rail I0 is at other than 90 with the post axis. The sole distinction is that the upper end 50 of post 26 is cut off at the appropriate rake or slope angle. It might be pointed out, however, that if the angle was slight, a transversely cut end could still be used, and the rail locked to the post, with all but one edge of the top of the post at an angle to rail surface 22. While this is not normally recommended, it is convenientwhere some slight misalignment may occur between the railand post.
In FIGS. 7 and 8, in place of the posts 26, the supporting elements comprise wall mounted brackets 52. Such brackets include a wall mounting plate 54 and an outwardly extending arm 56 carrying a pair of parallel walls 58, 60. Such walls are spaced and correspond to the post walls 28, 30 and are intended to enter between the rail flanges 20. After the walls are so inserted, the wedges 14 are driven home'in the manner previously described.
