Figs.- 8 and 9 are vertical, cross-sectional views taken onthe lines 88 and 99 respectively of Fig. 7, with Fig. 8' illustrating a filler strip disposed in closing-relation ship to the groove inthe lowermost face ;of each of the rails.
A railing assembly-broadly designated by the numeral 10 is shown in the drawing-in its preferred form, three rails 12, la-and 16 supported byupright structure -18 securedto the. vertical face-20 of astairway 22' by bracket means broadly numerated 24 being shown toillustrate the concepts of the invention although it is to beunderstood that a number of upright structures 18am- 4 normally provided-to support any desired number of rails such as 112, 14 and 16.
Each of the rails 12, '14 and 16 comprises anelongated, extruded metal bar-2'6 substantially trapezoidal in transverse configuration and thereby-having parallel, flat upper and lower surfaces 28 and 30 respectively interconnected by angular side faces '32 converging as upper surface28 is approached. Each ofthe bars 26 has alongitudi-nallyextending, centrally-disposed groove 34 in the normally lowermost surface 3li-thereof and defined in part by inner,
' longitudinallyextending groove faces 36 -para llel' with proximal side faces 32 of; bar 26. A longitudinally ex tending 'lug 38 integral-with bar 26withinthe groove 34 thereofand disposed centrally between opposed groove faces 36, is substantially dovetailed in transverse crosssectionandtherebyhas a pair of angular surfaces-'40 parallel with faces 36 as wellas a lower surface-42; parallel with surfaces 28--and 30 and- -spaced inwardly fromthe latter. The groove 34 in bar 26' is thereby;
substantially U-shapedin-transverse sectionandincluding' a pair of-angularly disposed slot-portions '44 converging as x 3 the innermost, longitudinally extending areas thereof are approached.
Structure 18 for supporting rails 12, 14 and '16 in verticallyspacedrelationship to stairway 22 includes a centrally disposed, elongated standard 46 which is sub-' stantially X-shaped in cross-section, as best shown in Fig. 3, whereby standard 46 has a plurality of longitudinally extending, circumferentially spaced, radial ribs 48 defining longitudinal recesses 50 therebetween at substantially 90 angles with respect to each other. Standards 46 may be of any desired length, but it is to be understood that the same should be of standard length to lower the production cost of railing assembly 10, inasmuch as the effective height of each standard 46 may be varied by changing the disposition of the same within bracket means 24 in a manner to be more fully defined hereinafter.
A connector broadly designated 52 is provided for each of the rails 12, 14 and 16 and serves to mount such rails in predetermined positions on standard 46. Each connector 52 includes a substantially rectangular element 54 having a rectangular passage 56 therein of dimensions substantially equal to the transverse width of standard 46, whereby the outer longitudinal margins of ribs 48 engage respective elements 54 within the corners of passage 56 therethrough. A pair of adjacent projections 58 integral with adjacent inner surfaces of each element 54 and extending inwardly into the passage 56 therethrough are adapted to be complementally received within corresponding adjacent recesses 50 in standard 46 defined by respective pairs of opposed ribs 48.
Frusto-conical extension 60 projecting outwardly from and integral with each element 54 is in alignment with projection 58 and is perpendicular to the axis of standard 46 when each connector 52 is mounted on the standard. A pair of identical, substantially Z-shaped clamps 62 are provided for securing respective rails 12, 14 and 16 to extensions 60 on corresponding elements 54, with each clamp 62 having a relatively short, angularly disposed leg 64 adapted to be received within a corresponding slot portion 44 of groove 34 in bar 26 and joined to a relatively long leg 66 by an intermediate length 68. As best shown in Fig. 2, clamps 62 are adapted to be positioned with the legs 66 thereof in abutting relationship and legs 64 received within corresponding slot portions 44 of bar 26. A stud bolt 70 passing through the lower ends of each leg 66 of clamps 62 and threaded into the outermost extremity of extension 60 rigidly secure respective rails '12, 14 and 16 to connectors 52. It can be recognized that the relative angularity of rails 12, 14 and 16 with respect to standard 46 may be changed by pivoting clamps 62 about the axes of bolts 70 and extension 60.
A number of spacer sleeves 72, 73, 75 and 77 are employed for maintaining connectors 52. and thereby rails 12, 14 and 16 in predetermined relative relationship and also vertically from stairway 22. Each of the sleeves 72, 73, 75 and 77 has four projections 79 integral with respective inner surfaces of the defined sleeves and slidably received within corresponding longitudinal recesses in standard 46. It can be seen that the number of spacer sleeves required will vary with the rails mounted on support 46 but in the railing assembly shown in Fig. 1, wherein three rails designated 12, 14 and 16 are mounted on standard 46, spacer sleeves 72, 73, 75 and 77 serve to maintain rails 12, 14 and 16 in proper spatial relationship on standard 46. Each of the spacer sleeves 72, 73, 75 and 77 comprises a rectangular tube 74 of internal dimensions substantially equal to the external transverse dimensions of standard 46 whereby tubes 74 are in slidable engagement with ribs 48 of standard 46. The longitudinal length of each tube 74 will depend upon the position at which it is desired to support a respective bar 26 but, in the assembly shown in Fig. l, spacer sleeve 72 is relative- 1y short, spacer sleeves 73 and 75 are of intermediate length, while lower spacer sleeve 77 is of substantially greater longitudinal dimension to thereby cause rails 12, '14 and 16 to be located in equally spaced relationship and at a proper level above the steps of stairway 22. Inasmuch as opposed adjacent ends of spacer sleeves 72, 73, 75 and 77 butt against elements 54 of connectors 52, it can be seen that reciprocation of connectors 52 on standard 46 is precluded so long as the defined spacer sleeves are prevented from shifting on standard 46. Means for preventing shifting movement of the spacer sleeves preferably comprises a frusto-pyramidal stop 76 coaxial with standard 46 at each end thereof and secured to the same by respective stud bolts 78 threaded into the outer extremities of standard 46. The greatest transverse dimension of stops 76 is disposed adjacent standard 46 and each stop is of sufiicient width to overlap a respective peripheral margin of one of the spacer sleeves 72 and 77 to thereby prevent reciprocation of the same on standard 46.
Bracket means 24 for securing structure 18 to face 20 of stairway 22 is preferably substantially U-shaped in transverse cross-section and thereby includes a longitudinally extending bight portion 80 adapted to be secured to face 20 of stairway 22 by a number of bolts 82 extending through bight portion 80 into stairway 22 and having the heads 84 thereof recessed within depressions 86 in the normally innermost face of bight portion 80. Parallel, opposed leg portions 88 integral with bight portion 80 are adapted to embrace corresponding, opposed sides of spacer sleeve 77, while the inwardly turned, spaced, parallel tab portions 92 integral with the longitudinally extending margin of each leg portion 88 engage the normally outermost face of spacer sleeve 77 to thereby retain structure 18 within bracket means 24. Setscrews extending laterally through leg portions 88 engage opposed outer faces of spacer sleeve 77 to maintain structure 18 in predetermined relationship relative to bracket means 24, yet permitting vertical adjustment of structure 18 to any one of an infinite number of positions relative to bracket means 24. Upper and lower edges 94 of bracket means 24 are preferably beveled so that the same converge as tab portions 92 are approached to thereby eliminate to a certain extent, sharp corners on bracket means 24 and also enhancing the appearance of bracket means 24.
In order that a pair of bars 26 may be connected in end-to-end relationship to present one of the rails 12, 14 or 16, a splicer broadly numerated 96 is provided for interconnecting abutting ends of bars 26 without detracting from the overall appearance of the rail assembly. As best illustrated in Fig. 9, splicer 96 comprises an elongated, substantially U-shaped component having a pair of angularly disposed, longitudinally extending segments 98 adapted to be received complementally within corresponding slot portions 44 of bars 26, with segments 98 being integral with and interconnected by a central section 100 configured to be disposed within groove 34 in engagement with surfaces 42 of lugs 38 and flush with normally lowermost surfaces 30 thereof.
A pair of bars 26 are interconnected in end-to-end relationship by first inserting splicer 96 into the groove 34 in one end of a bar 26, whereupon the end of another similar bar is shifted into a position abutting the first bar with splicer 96 also located in the groove 34 thereof.
In order to close the normally open groove 34 in each bar 26 and not occupied by clamps 62, a filler strip 102 may be provided and of a length equal to the distance between connectors 52 joined to the same rails 12, 14 or 16 or between such connector and a splicer 96. Each filler strip may be constructed of an elongated, flat wall 104 of a width substantially equal to that of groove 34 adjacent surface 30 of bar 26 and including integral, inwardly projecting, longitudinally extending, parallel spring clips 106 disposed to engage angular surfaces 40 of lug 38 to thereby releasably maintain filler strip 102 in closing relationship to a respective groove 34. Elons gated spacers 108 integral with. wall 104,, parallel with spring. clips- 106, are of: -sufiicientwidth: =to "be received within anrelongated :channel 110 in: surface 42. ofxeach lug 38; spacers '108:maintaining1filler strips 102'in'flush relationship with .respectivezsurfaces' 30 ofrbars 26.
The manner in -whieh. the various components J of railing assembly 101 are :assembledzis' believedto'be obvious from the abovedescriptiongbutit is to be'emphasized that anwimporta'nt 'advantage 'of. the instantirailing unit is therfact'f that the same-:mayr be; placed. in: position on stairway 22i-in: a iminimum 'of timeatinasmuch as his only necessary-to .slip: elements"54 of connectors 52 over standard 46 in conjunction with the proper spacer sleeves 72, 73, 75'- and' 77,-'follow'ed by--securingof-stops 76 to respective endsof =st-andard'46-and threading of bolts '70 through legs 66 of clamps 62 and into extensions 60. The relative height of -rails-12, 14and 1'6 with'respect t0 stairway 22 may bereadilyadjustedby shifting spacer sleeve 77 within bracket means 24 upon loosening of setscrews 90, while the angularity of rails .12, 14 and 16 with respect to structure 18 may be varied by rotating clamps 62 secured to rails 12, 14 and 16 about the axis of corresponding extensions 60.
Another feature of the invention is 'the fact that a large proportion of the components of assembly may be manufactured at a minimum cost through conventional extrusion procedures. This is true of bars 26, standard 46, spacer sleeves 72, 73, 75 and 77, splicers 96 and filler strips 102. Furthermore, bracket means 24 may be formed of sheet material suitably bent into configuration if desired.
Another important advantage of railing assembly 10 is the manner in which the relative distance between rails 12, 14 and 16 may be easily changed as desired by merely utilizing spacer sleeves 73 and 75 of different lengths. In this respect it can be appreciated that an elongated tube 74 may be provided with assembly 10 whereupon the contractor may out such tube into desired lengths to present spacer sleeves for maintaining connectors 52 in predetermined relative relationship.
The utilization of substantially Z-shaped clamps 62 is also of importance because of the manner in which rails 12, 14 and 16 are effectively secured to connectors 52 without any type of additional fastening means in the nature of bolts or the like being required and which would not only detract from the appearance of railing assembly 10 but would also increase the fabrication time thereof.
