TECHNICAL FIELD
The present disclosure relates to beam mounted chair assemblies. More particularly, the present disclosure relates to beam mounted chair assemblies for auditoriums, cinemas, concert halls, arenas, gymnasiums, theaters and various other venues, and to chair assemblies for use within the beam mounted chair assemblies, components for use within the chair assemblies and parts for use within the components having associated chair brackets and standards secured to a beam such that the chair brackets and standards may be positioned at any location along a full length of the beam without interfering with one another.
BACKGROUND
In the past, buildings such as cinemas, theaters, concert halls, arenas and other areas of public entertainment have been provided with beam mounted chair assemblies. However, more recently there has been a tendency for such buildings to serve more than one purpose. For example, a building for public entertainment may be required on one occasion to serve as a sports hall, and on another occasion to serve as a concert hall or theatre. Similarly, seating arrangements in concert halls, theatres or arenas may need to be reconfigurable to suit the requirements of a particular production being staged.
Tiered seating systems have been devised which, when not in use, can be folded or otherwise collapsed against a wall of the building in which they are situated (e.g. telescopic seating systems such as those disclosed in commonly assigned patent application Ser. No. 61/856,013, entitled Telescopic Seating Systems, and Foldable Chairs and Related Components for use within Telescopic Seating Systems, filed Jul. 18, 2013 and Ser. No. 61/868,547, entitled Telescopic Seating Systems, and Foldable Chairs and Related Components for use within Telescopic Seating Systems, filed Aug. 21, 2013), thus freeing the floor area for other purposes. However, there has, so far, been no satisfactory solution to the problem of installing reconfigurable seating on a sloped floor.
Seating for an audience in a public building or arena must comply with statutory regulations. These regulations are principally intended to ensure that the building or arena can be evacuated rapidly in the event of an emergency. Thus, there is a minimum spacing which must be observed between adjacent rows of seats, and provision must be made for preventing the rows of seats from moving relatively to one another in a way which would reduce the spacing below this minimum during installation.
One way of meeting the statutory requirements is to secure a beam to standards and secure chairs to the beam while each is installed, but this is unsatisfactory. Furthermore, installation and removal of the seats are very time consuming and require skilled labor when the beam is secured to the beam and the individual chairs are secured to the beam while individually being installed.
SUMMARY
Beam mounted chair assemblies may include at least one standard supported on a floor, a curved beam supported by the standard, and a plurality of chair assemblies supported by the beam. A beam may be stably supported on the standard and chair assemblies may be stably supported on the beam such that the beam and the chair assemblies may be set in position during installation without securing the beam to the standard or securing the chair assemblies to the beam.
Beam mounted chair assemblies may include at least two standards supported on a floor, a beam supported by the standards, and a plurality of chair assemblies supported by the beam. A beam may be stably supported on standards and chair assemblies may be stably supported on the beam such that the beam and the chair assemblies may be set in position during installation without securing the beam to the standards or securing the chair assemblies to the beam.
Beam mounted chair assemblies may include at least two standards supported on a floor, a beam secured to, and supported by, the standards, and a plurality of chair assemblies secured to, and supported by, the beam. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another.
Chair assemblies may be secured to a beam via associated chair brackets. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another.
Chair brackets may include chair seat pivots that pivotally secure a chair seat in proximity to a chair back such that the chair seat may pivot between an up and a down position. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another.
Standards may extend horizontally from an associated structure, vertically from an associated structure (e.g., a floor) or a combination thereof. Chair brackets and standards may be secured to a beam such that the chair brackets and standards may be linearly positioned along a full length of the beam without interfering with one another.

DETAIL DESCRIPTION
A beam mounted chair assembly is provided where associated chairs may be stably held in place prior to tightening any fasteners thru standard, beam and chair features cooperating with a mechanical moment provided by each chair's center of mass or chair mass properties (e.g., include magnetic beams). Individual chairs may be slid along a full length of a beam without interfering with any standards. While no interference between a standard and a chair bracket is preferred, it should be understood that there may be interference between a standard and a chair bracket in certain circumstances. A clamp system may be provided between a standard and a riser/floor. A lower clamp system may be provided between standards and a beam that stiffens the beam to reduce deflection include torsional deflection such that fewer attachment points (standards) are required. A beam mounted chair assembly may be provided that works for some or all chair installation types (e.g., telescopic chair installations, movable chair installations, fixed position chair installation, etc.). A beam mounted chair standard may be floor mounted. Alternatively, beam mounted chair assemblies of the present disclosure may be incorporated in any installation type (e.g., riser mount, telescopic, movable, linked, etc.).
A beam may be manufactured from a solid material. Alternatively, a beam may be optimized for strength and cost by reducing beam material, for example, by using a box beam or an extruded beam with internal, laterally extending, void areas (e.g., as depicted in FIGS. 3J and K). Interface surfaces between a standard and a beam and/or between a beam and a chair bracket may be substantially flat. Alternatively, interface surfaces between a standard and a beam and/or between a beam and a chair bracket may have non-flat geometry as illustrated, for example, in FIGS. 3G, 3J and 3K. Non-flat interface surfaces between a standard and a beam and/or between a beam and a chair bracket may induce a retention feature under load, for example, when a corresponding clamp is tightened.
Additional member(s) may be added between the standard and the beam to strength the system while minimizing cost. These members will cooperate with the standard and the beam to enhance the system performance. Cooperation between members may be enhanced by features such as pockets or protrusions in any or all adjacent members which engage adjacent members. Adjacent members may be fastened to enhance system performance. Fastening may take the form clamps, welds, bolts, adhesives or other means of linking adjacent members to enhance system performance. Fastening does not require properties to be isotropic and one skilled in the art can envision antistrophic methods which will enhance performance while lowering system cost. A reinforcement beam may extend parallel to a main beam to strengthen an associated beam mounted chair assembly. An added pocket may be provided within associated standard/mounting feet or within the beam to hold a support beam that may be added to spread the mounts. A reinforcement beam and/or a support beam may be an I-beam. Alternatively, a reinforcement beam and/or a support beam may be any shape. A beam may be clamped to a support beam to handle torsion loads. Corners of associated parts of a beam mounted chair assembly may be sharp. Alternatively, corners of associated parts of a beam mounted chair assembly may have radii added for manufacturing, stress reduction, safety, etc. A beam mounted chair assembly may include chairs that are held in place prior to tightening fasteners by using beam and/or chair features that may cooperate with a moment provided by an associated chair's center of mass. Chairs of a beam mounted chair assembly may slide along a full length of a beam to adjust for chair sizes. A beam mounted chair assembly may incorporate associated clamp systems between standards and risers/floors that may be position at any point along a length of a beam. A beam mounted chair assembly design may not require a standard and an associated mounting foot to be offset from one another. A beam design may be symmetrical to reduce installation labor.
Beams may be joined by internal coupling components to allow unrestricted beam length. Coupling components of a standard, a beam and/or a chair bracket may include external features which control insertion depth to aid beam mounted chair assembly installation. Coupling components of a standard, a beam and/or a chair bracket may include features such as slots cut in a round tube to facilitate alignment and to aid assembly. Features described above may vary in geometry (depth, width, quantity, etc.) to aid insertion depth control. For example, a lower clamp system may include features that stiffen an associated beam and/or reduce beam deflection and/or required attachment points. A beam stiffening member and a beam may extend into one another to facilitate installation. Mating surfaces between a beam stiffening member and a beam may extend above or below a top of an associated pocket. Pockets may be attached to a beam allowing for stiffening member/beams of multiple materials and/or component construction.
A beam mounted chair assembly may incorporate fasteners accessible from a top side, a front, a bottom side and/or a back side of an assembly. Beam geometry may be designed to avoid accumulation of water, dirt, debris, etc. A beam mounted chair assembly may incorporate blow molded chair seats and/or chair backs. Blow molded chairs traditionally locate associated chair seat pivot mechanisms below a chair mounting surface. A beam mounted chair assembly may have a chair seat pivot mechanism above an associated chair mounting surface.
