Af/away ATTORNEY United States Patent Ofiiice 3,372,909 Patented Mar. 12, 1968 3,372,909 ANCHOR AND BRACKET ARRANGEMENT FOR RAIL Julian J. Attaway, 4520 Elrndale Drive, Tucker, Ga. 30084 Filed Oct. 11, 1966, Ser. No. 535,800 6 Claims. (Cl. 25669) This invention relates to new and useful improvements in railings and in rail mountings, and more particularly is concerned with a bracket wherein there are features which share with a rail for the rail to be engaged and supported to a support structure.
Among the objects of the present invention is the provision of a practical and reliable rail and bracket arrangement having an anchor therein which is easy to assemble with a rail and be engaged with a support structure, and which arrangement furthermore contributes selectivity between having the rail and the anchor in the assembly interlocked laterally of the rail with freedom for adjustment in the relative positioning thereof to be made longitudinally of the rail and having the rail and the anchor interlocked laterally of the rail and securely held against relative movement longitudinally of the rail.
Other objects of this invention will in part be obvious and in part pointed out more fully hereinafter.
In connecting rails to a support structure such as to posts or a wall, and for such purposes as to achieve railings for stairways or railings for other indoor or outdoor uses, problems heretofore have been encountered in achieving placement of a rail in a desired position longitudinally thereof with reference to the rail support brackets. Often it has been a problem that to secure the brackets to the support structure and thus support the rail destroys maneuverability of the rail longitudinally of the rail so that a more exacting allocation of the supported rail endwise of the rail cannot be achieved except perhaps through loosening the brackets on the support structure enough to allow the adjustment, this at the sacrifice of maintaining any particular lateral position of the rail relative to the support structure. Through lack of sustaining a position of the latter kind it is difficult to effect a longitudinal movement of the rail and have the brackets guide the movement. Furthermore many of the brackets in the prior art are of types which in no way can be shifted with respect to the rail along the length of the rail and thereafter be secured to fix a new position on the rail.
Such as to avoid the cumbersome arrangement of having the bracket surround the exterior of the rail, it has heretofore been the practice to engage the bracket and rail interiorly of the rail. Practices of the latter sort often have failed to offer an adequate solution to the problem of insertion of the bracket in the rail and therefore have required activities other than at the desired point of vantage during installation or an order of working which is objectionable.
Another object of this invention is to provide a rail and bracket arrangement wherein a pair of lugs of an anchor and a rail are constructed for an inner portion of each of the lugs to be inserted laterally of the rail starting from a region selected between the opposite longitudinal ends of the rail to introduce the inner portions of the lugs into a longitudinal slot in the rail, with an inner enlargement of the slot enabling the pair of lugs to be disposed in an opposed relation and connected externally of the rail to have the inner portions thereof interlocked with the rail laterally of the rail and yet have the pair of lugs remain in a relatively movable relation with the rail before being connected to the rail to fix the position of the lugs relative to the rail.
The present invention accordingly embodies a rail and bracket arrangement wherein there is an anchor including a pair of discrete lugs having contacting legs for the lugs to be back to back and each of the lugs having a lateral extension of the leg thereof, for the anchor to be generally T-sha-ped in transverse cross section and outer ends of the extensions to be outward from opposite sides of the legs when the lugs are securely held back to back. There is a set screw for at least one of the lugs and the screw threadedly engages the lateral extension of the lug within an opening leading from a first side of the extension to a second side of the extension in a direction away from the leg of the lug and having a driving end which is accessible adjacent to the first side and an inner end to advance outside the second side. A rail having an inwardly laterally oppositely enlarging longitudinal slot entering the underneath side thereof is characterized by the slot being of a size and proportion for each of the lugs separately to have the lateral extension of the lug inserted into the slot laterally of the slot and the pair of lugs brought into the aforementioned back to back relation and securely held having the extensions slidable longitudinally of the rail in the slot and interlock with the rail laterally of the rail for the set screw to be driven to have the inner end thereof engage the rail inside the slot and secure the anchor against movement along the length of the rail. A connector means associated With the anchor forms a bracket with the anchor and in doing so serves for engaging the legs of the pair of lugs in the aforementioned back to back relation of the lugs to a support structure, having the lateral extensions of the pair of lugs inserted in the slot to interlock the anchor with the rail.
In the accompanying drawing representing a structure wherein the present invention is embodied:
FIGURE 1 is a side elevation of a railing wherein posts and a hand rail are shown broken away having interconnecting brackets;
FIGURE 2 is a top URE 1;
FIGURE 3 is a transverse cross section taken at 3-3 in FIGURE 1 having the rail and bracket secured to the post; and
FIGURE 4 corresponds to FIGURE 3 and is a View partially exploded and partially in transverse cross section with the post screw indicated broken away.
Like reference characters denote like components throughout the several figures of the drawing.
Turning now more particularly to FIGURES 1 and 2 of the drawing, a railing 10 including as a portion thereof at least one rail 11, such as a hand rail, and a plurality of brackets 14, is associated with a firm support structure which in the present instance comprises the vertical posts 12 suitably secured at lower portions thereof not shown. For each of the posts 12, one of the brackets 14 of the railing 10 interconnects the rail 11 with the post. Also, in the present embodiment an inner longitudinal end 11a of the rail abuts wall 13 of a building or the like and has an outer longitudinal end 11b which for example may be a terminal end of the railing 10 as shown or the railing may include a further section having a rail similar in cross section to the aforementioned rail, abutting the end 1112 and extending longitudinally from that end while securely supported on brackets of the character described herein.
Rail 11 has a longitudinal slot 15 (see FIGURES 3 and 4) entering the underside continuously from end 11a to end 11b of the rail subject of course to having the slot interrupted locally at a point or points along one length of the rail as by cutting or drilling to meet specialized demands under certain circumstances. The slot 15 is of uniform transverse cross section throughout while being plan view corresponding to FIG- 3 -elatively narrow in the region of the entrance into the inderside of the rail and widens inwardly of the rail in :ach of opposite directions laterally of the rail. Thus, 15 components of the rail 11, there are laterally and ongitudinally extending integral members 16 and 17 having spaced opposed lateral ends 16a and 17:: at the entrance of the slot 15. Inwardly of the rail the members 16 and 17 have faces 16b and 1% between which and the still farther inward surface 110 of the rail 11 the slot 15 enlarges giving side cavities 15a and 1511. Rail 11 in the present embodiment is a metallic product of extrusion, although the rail may instead be made from any suitable material or materials and by any suitable production method as occasion may demand. Also, in the particular embodiment shown the slot 15, regarded in transverse cross section of the rail 11, has the general configuration of a T which is upright with reference to the underside of the rail.
Since all of the brackets 14 in the railing are substantially alike, a description now to be directed to the structure of one of the brackets in association with that of the rail 11 while having reference to one of the posts 12 will give an adequately detailed insight to the structure of the railing 10 and provide an example of how the railing may be mounted. Thus, referring more particularly to FIGURES 3 and 4, bracket 14 includes an anchor 13 com-prising a pair of similar discrete lugs 19 and 20 and connector means including a sleeve 32 and a main mounting screw 33 of the bracket by which the lugs 19 and 20 and the rail 11 may be supported to the post 12, having the pair of lugs inserted in the slot 15 to interlock the anchor 13 with the rail. The lugs 19 and have contacting legs 1% and 26a for the lugs to be back to back at their legs, and the lugs have lateral extensions 19b and 26b which are integral with the inner ends of the respective legs 19a and 23a, for the anchor 18 to be generally T-shaped in transverse cross section and outer ends 190 and 26c of the extensions 1% and 26b to be outward from opposite sides of the legs 19a and 20a when the lugs of the pair are securely held back to back. In the present arrangement the lateral extensions 1% and 20b compositely are generally T-shaped themselves in transverse cross section in the back to back relation of the lugs 19 and 20 and, as such, are of a size and proportion to be slidable longitudinally of the rail 11 in the slot 15 and interlock with the rail members 16 and 17 and secure the anchor 18 to the rail laterally of the rail when the lugs 19 and 20 are securely held. A further feature resides in the fact that the lugs 19 and 2t) and the slot 15 are proportioned for each of the lugs to be inserted one at a time into the slot to achieve their back to back relation this by first bringing the lateral extension of one of the lugs into the slot laterally of the slot to behind one of the rail members 16 and 17 and in turn bringing the lateral extension of the other of the lugs into the slot laterally of the slot to behind the other of the rail members and then relatively moving the lugs in the slot to establish the back to back relation.
Set screws 22 and 24 threadedly engage the lateral extensions 1% and 20b of lugs 19 and 21) respectively in openings 23 and 25 leading from first or outer sides of the extensions in a direction away from legs 19a and 21):: and the screws have driving ends 22a and 24a adjacent to the respective first sides of the extensions and inner ends 22b and 24b to be advanced beyond the respective second sides and apply thrust from the anchor 18 to the rail 11, having the extensions 1% and 20b interlocked in the slot 15 with the rail members 16 and 17 against escape laterally of the rail and the extensions immobilized by means of these screws against movement longitudinally of the rail.
The legs 153a and Mia have lateral openings 31 and 31 which are in alignment concurre tly with the legs having the back to back rela hereinbefore described, The connector means associate-u in the bracket 11: with the anchor 18 is installed by introducing the sleeve 32 endwise outside leg 19a to receive the main mounting screw 31 in the bracket. Screw 33 is added to have its head 33a outside leg 20a and its shank 33b reaching through the le openings 31 and 31 and through the sleeve 32. Threads available in the screw shank 33b beyond the far end of the sleeve from the anchor 18 are engaged with threads in the post 12 and the screw 33 is tightened to secure the legs 1% and Ztla and sleeve 32 to the post and clamp the legs securely between the head. 35a and the sleeve, having the lateral extensions 1% and Zdb engaging the rail 11 in the rail slot 15. A thimble or cap 4t) having a radial set screw ttla covers the head 33/1 of the main screw to the adjacent face of leg 29a and is held to this screw head by the set screw endwise in contact with this head.
Referring to the railing 10 in FIGURE 1 and to each of the brackets 14 installed on the related post and engaging the rail 11 in the manner just described, it will be appreciated that the rail 11, on having the set screws 22 and 24 in released positions in the anchors 18, may be longitudinally moved on the anchors while still later ally interlocked with the anchors, such as to attain abut merit against the wall 13 or any desired extent of clear ance from this wall, and then be longitudinally fixed in position by setting the screws 22 and 24 in the anchors to their holding portions against the rail.
In the present embodiment, the lugs 19 and 20 are provided with means for interconnecting the lugs in their back to back relation before the sleeve 32 and main screw 33 mount and clamp the anchor to the post Thus, a further fastening in each of the anchors 18 includes a headed screw 26 and involves the legs 1% and 21111 and apertures 27 and 28 axially directed laterally of these legs, the first of these apertures being in leg 1% between Opening 30 and the lug extension 1% and the second of these apertures leading into but preferably not all the way through the leg 26a for the two apertures to be in open axial alignment with each other in the previously described back to back relation of the legs. The shank of screw 26 has a reach through apertures 27 and 28 whereby the head of the screw preferably and, as shown, is outside leg 1%, thus eventually to be concealed toward the post 12 or support structure, and the shank engages leg 29a in the aperture 28 for the screw to be tightened and secure the back to back relation of the legs. Although in certain embodiments still in accordance with the present invention the means for fastening the legs 19a and 20a together in advance of the bracket 14 being mounted to the support structure may be omitted from the anchor structure, it will be appreciated that through use of the fastening, directly as a component of the anchor, a number of advantages are had including the fact that where desired the anchor lugs may be installed in the rail slot 15 and he fixed in position longitudinally of the rail by the set screws 22 and 24 before mounting the anchor to the support structure.
As the invention lends itself to many possible embodiments and as many possible changes may be made in the embodiment hereinbcfore set forth, it will distinctly be understood that all matter described herein is to be interpreted as illustrative and not as a limitation.
