Definitions
- the framework includes parallel support rails that cooperate with a peripheral planar area or portion and overhanging lips at the front and back for nonstressing support of the seat modules. Embossments on the lips provide transverse snugness. Laterally extending finish strips cover the joint between the seats and hold down the edges, and also cover the embossments.
- a slot is provided along each rail for receiving a bolt; a barrel nut being driven on the bolt to fasten the seat modules in position with only top drive being applied.
- the bolt head is sufiiciently narrow to drop between the shoulders of the slot whereupon the sides of the slot limit rotation of the bolt to an oblique angle and insure engagement of the head with said shoulders in fastening relationship.
- the nut includes a cylindrical body having a lower face for engagement with the framework in frictional locking relationship; the body being substantially the same length as the thickness of the panels (such as the finish strip and seat or transport trailer skin) to obviate compression stresses within said panels and allow a floating interconnection for differential expansion and contraction and mechanical
- the present invention relates to modular seating and, more particularly, to an improved combination of modular seats and supporting framework for installation in a stadium or the like.
- Wood is an ideal material in that it has a relatively low coefficient of thermal expansion and contraction and high resiliency, as well as a low heat transfer coefficient. Thus, it is ideal for preventing damage resulting from differential expansion and contraction with respect to its base and from vibrations, and in providing a temperate seat on which to sit.
- Wooden components have always suffered the inherent disadvantage of eventually being subject to deterioration from weathering and the attendant high cost of maintenance, including annual painting.
- the modular seating concept wherein seats of unitary molded plastic material are assembled in juxtaposition on a support has appeared on the scene.
- the concept offers outstanding potential in terms of initial low cost since the seats are formed of thin, vacuum molded plastic, and promises even greater savings in terms of being maintenance-free for the life of the stadium.
- Another advantage of the modular seats is outstanding spectator or user appeal in that they may be fully contoured to fit the human anatomy, they provide insulation "Ice from extreme heat and cold, and they are permanently colored for aesthetic purposes and stadium section identification.
- One recent patent, illustrating this broad concept and owned by the assignee of the present invention, is the patent to Motter 3,466,087, issued Sept. 9, 1969.
- the present invention provides contoured seat modules having several features particularly adapting the same for securing to an elongated framework in juxtaposition with like modules in a snug fashion and so as to prevent stresses in the modules due to ambient thermal variations and vibrations.
- the seat module is made of a unitary sheet of plastic material, which material may be brightly colored to enhance the attractiveness of the stadium and to conveniently provide color coding for different sections of the stadium.
- the central portion is raised and contoured to fit the anatomy of the spectator or user.
- An outer peripheral planar portion provides an extended area across the full width of the front and back for support of the module on the framework which prevents the weight of the spectator from causing deleterious stresses in the plastic material that would, like the thermal variations and vibrations, eventually lead to fracture and cracking.
- Embossments are formed adjacent the sides of the seat modules on the overhanging lips that insure the seat of having a snug fit on the framework in the transverse direction with respect to said framework; the center expanse of the lips being free to move in or out to accommodate differential expansion and contraction between the module and the framework in the same transverse direction.
- the framework preferably comprises a pair of parallel runner rails, the top surfaces of which engage the planar supporting surface of the seat modules along the front and rear. Also provided are cantilever channels formed in the rails which are engaged by the front and rear depending lips for transverse positioning of the modules. Slots are formed along the length of the rails for adjustably receiving a threaded bolt which, with a barrel nut, forms the fastener means holding the seat modules in position.
- the nut includes a cylindrical body having a length equal to the thickness of the seat and finish strip that conceals the joint between two adjacent seat modules.
- the lower face of the cylindrical body is adapted to frictionally lock into engagement with the opposite or upper side of the retaining shoulders of the slot that holds the head of the bolt against upward movement; the bold head being sufiiciently narrow to drop into the slot at any position along the length for ease of installation and then turn to an oblique angle as limited by the sides of the slot in fastening relationship with the shoulders.
- the framework includes a cross bar to connect the rails; an inverted U clamp engaging a groove on the rails to lock the same in position for easy on-site attachment of these parts.
- Either a vertical riser support or tread support may be attached to the cross bar for support of the assembly on the usual stepped concrete stadium base.
- nonstressing fastener and cooperating rail mount of the present invention may be translated into other fields, such as the field of fabrication of trailer truck skin.
- the rails form the framework for the trailer body and the outer panels are attached in the same manner as the seat modules and/or the finish strip means with the same resultant self-locking feature of the fasteners.
- the prevention of stressing and cracking of the panels due to road vibrations and expansion or contraction due to change in thermal conditions represents a significant advance in these other fields.

- FIGS. 1-3 of the drawings wherein is shown a stadium seating assembly, generally designated by the reference numeral 10, and including a framework 11 fabricated of suitable parts of metal, such as aluminum, and a plurality of seat modules 12, formed of any suitable high strength plastic material, such as high density polyethylene.
- the seat modules 12 are formed of sheet material with a raised central portion 13 having a contour suited for comfortably accommodating the users anatomy.
- the preferred embodiment is made by vacuum molding in a single-step operation; although it is to be understood that other methods of fabrication can be used if desired.
- the framework 11 comprises a pair of parallel rails 15, 16, the top, planar surfaces of which serve to support the seat modules 12 along the front and rear in a normal, horizontal position.
- Cross bar 17 is provided to interconnect the rails 15, 16 and to support the same from vertical riser support member 18.
- the cross section of the cross bar 17 and the riser member 18 can be of any suitable configuration to give the requisite strength to the framework 11 and for purposes of illustration of the preferred embodiment the cross bar 17 is shown as a T section and the riser member is shown as an angle (see FIGS. 1 and 3).
- the riser member 18 may be suitably mounted on riser face 19 of a conventional stepped stadium base as shown in FIGS.
- the framework 11 may be supported from the tread 20, as shown by tread support member 18a in FIG. 3a.
- tread support member 18a in FIG. 3a.
- the attachment of the riser and tread members 18, 18a may be by suitable stud and bolt combinations 21, 21a, respectively, and the interconnection of the cross bar 17 to the riser and tread members 18, 18a may be by bolt and nut combination 22 (see FIG. 3); although it is to be understood that other conventional types of fastening might be used at these points if desired without departing from the broad prin ciples of the invention.
- the raised, contoured portion 13 is defined by an outer, vertical wall 25 extending along the front and two sides and curving around the back at both sides.
- a ridge 26 dimensioned to fit between the legs of the user in a seated position, which ridge tapers to the rear toward the dished-out section and to the front to provide a surface suitable for marking of the desired seat number.
- Extending peripherally around the outside wall 25 is a planar portion 27 that provides the seat with a level undersurface area to mate with the top plannar face of the front and back rails 15, 16 in supporting relationship therewith.
- embossments 35, 36 to insure spacing of the lips 30, 31 away from the framework 11 under all ambient thermal conditions.
- the convex protrusion on the underside surface of the module 12 spaces the lips 30, 31 away from the channels 32, 33. This allows the central expanse or major length of the lips to freely move in and out with respect to the channels 32, 33 in order to accommodate differential expansion and contraction between the modules 12 and the framework 11.
- the embossments 35, 36 engage the outwardly extending face of the channels 32, 33 along a substantial line contact so that slack between the seat modules 12 and the framework 11 is more effectively prevented. Further, the embossments 35, 36 have sufficient frictional engagement with the channels 32, 33 to resist any tendency toward lateral shifting of the modules 12 along the rails 15, 16.
- the juxtaposed modules 12 are fixed in position by fasteners F including an upstanding bolt 40 and barrel nut 41, which fastener extends between and abuts the sides of the modules 12 and thereby allows a modified floating interconnection therebetween as will presently be seen.
- Each bolt 40 cooperates with the rails in such manner that a tool for activating the fastener is required to be employed only from above.
- FIGS. 5 and 6 wherein it can be seen that the bolt 40 includes an elongated head 42 that is adapted for positioning in a slot 43 along each of the rails 15, 16. As illustrated, the slot has opposed retaining shoulders 44, 45 along top thereof for holding the head of the bolt against upward movement.
- the bolt is permitted adjustable horizontal movement with respect to the framework 11 along its entire length by simply grasping the upstanding threaded portion and moving the same as desired.
- the barrel nut 41 is driven onto the bolt 40, and due to the frictional forces between the corresponding threads, the head 42 is initially rotated to an oblique angle so that the ends thereof are automatically in cooperative or locking relationship with the shoulders 44, 45.
- the side walls of the slot 43 limit the movement of the bolt head 42 to thereby provide the final locking position of the head 42 with respect to the shoulders 44, 45.
- the heads 42 are sufliciently narrow to pass between the shoulders 44, 45 when extending along the longitudinal axis, as shown in the full line position of FIG. 6.
- the fasteners F extend between the adjacent edges of the modules 12 to form an open joint 50 (see dotted line showing in FIG. 2, and see FIG. 7).
- the juxtaposed modules 12 are mounted in a positive and secure manner, but yet are capable of modified floating movement at the interconnections by virtue of the required expansion and contractron in both the longitudinal and transverse direction with respect to the framework 11 to prevent deleterious stresses.
- the contacts made by the embossments 35,, 36 and the fasteners F insure this capability while at the same time always insuring a snug fit between the parts.
- the fastener means F are securely locked in position in an automatic fashion as they are driven into final position. That is, lower face 55 of the barrel nut 41 is provided with a frictional surface that is adapted to cooperate with the upper surface of the rails 15, 16, and in particular, the side of retaining shoulders 44, 45 opposite from the head 42 of the bolt 40, as shown in FIG. 4. It should be noted that the nut 41 and the head 42 thus act on substantially directly opposite sides of the shoulders 44, 45 with equal and opposite reactions and thus no force tendmg to strip out the shoulders 44, 45 is experienced due to the tightening action.
- the torque with which the barrel nut 41 is driven into final position is controlled by adjustment of the power tool being used.
- the preferable adjustment is for sufiiciently high torque to cause the lower face 55 to form a partial cold weld; that is, a partial fusing together of the adjacent molecules in the contact area between the lower face 55 and the upper face of the shoulders 44, 45 due to the frictional heat generated by the galling action (see FIG. 6).
- the barrel nut 41 like the rails 15, 16, is fabricated of an aluminum alloy so as to be relatively soft and thus capable of readily forming such a weld.
- the lower face 55 of the barrel nut 41 may, if desirable or necessary, be provided with a plurality of rearwardly extending teeth to form a serrated surface as shown in FIG. 5.
- the knife edges of the serrations more completely resist any tendency for reverse rotation by biting into the metal face of the rails 15, 16.
- a lateral finish strip 60 is mounted between adjacent seat modules 12 by the barrel nuts 41, as shown in FIGS. l-4.
- the apertures 61, 62 through which the nuts 41 pass are slightly oversized to accommodate the required degree of expansion and contraction of this part.
- the head of the nut 41 is adapted to frictionally engage the upper surface of the finish strip 60 so as to firmly hold the same down and transfer a downward holding force in turn to the edges of the seat modules 12 aloing the surface of the planar area 27.
- the strip 60 and the planar portion 27 of the seat module 12 are not subjected to compressive stresses as in prior arrangements by virture of the feature of making the cylindrical body of the nut 41 a length substantially equal to the combined thicknesses of these parts.
- the finish strip performs the function of concealing the open joint 50 between the juxtaposed modules 12 (see FIG. 2). Furthermore, the embossments 35, 36 are positioned at the edges of the lips 30, 31 and thus the finish strip 60 will also cover these elements. End finish strips 65 are provided with end wall 66 in order to conceal the framework 11 at the end of a row of seats.
- the modular seat 12 is provided with a planar peripheral area 27 that rests on a corresponding fiat surface of the framework 11 so as to provide a secure support relationship.
- the fastener means F comprising the bolt 40 (adjustable along the rails 15, 16 in a slot 43), and the barrel nut 41 locks in position to hold the modules 12 on the framework 11.
- the body of the nut is substantially the same length as the thickness of the finish strip 60 and seat edge so that substantial compressive stresses in the plastic are avoided.
- the arrangement of the fasteners F in combination with a mounting framework is contemplated by us as having certain utility out of the seating field but still coming within the bounds of the present inventive concept.
- the mounting of corrugated panel 60a or flat panel 60b on the rail for forming an enclosure has certain very important advantages.
- the panels 60a, 60b in the trailer environment are commonly made of aluminum sheets and the prevention of stresses allows the use of thinner gauge material for a substantial savings in cost while maintaining the integrity and watertightness of the trailer body.
- a modular seating assembly for stadiums or the like comprising an elongated support framework presenting a substantially fiat horizontal plane, a plurality of separate seat modules mounted in juxtaposition in a row on said framework, said seat modules having laterally extending substantially fiat planar portions cooperating with the horizontal plane of said framework for support and defining side edges, and fastener means outside said planar portions extending between and abutting the side edges of said modules and cooperating with said framework for fixing said modules in position while allowing differential expansion and contraction of said framework and seat modules and allowing movement of both juxtaposed edges in a plane toward each other during such expansion and contraction, said fastener means extending in a direction across said row substantially less than the full width of said row, the movement of said side edges toward said fastener means being accommodated by localized deformation of said edges at said fastener means.
- said fastener means includes a first upstanding threaded member extending between said modules and a corresponding second threaded member for driving between said modules on the first threaded member, and locking means including a lower frictional surface on said second member en gaging the upper face of said framework upon being driven into final position.
