The drawings are primarily for illustrative purposes and are not intended to limit the scope of the inventive subject matter described herein.

    DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

    (25) Definitions. As used in this description and the accompanying claims, the following terms shall have the meanings indicated, unless the context otherwise requires.

    (26) A set includes one or more members, even if the set description is presented in the plural (e.g., a set of Xs can include one or more X).

    (27) Attach (e.g., as in attached to or attaches to) is open-ended and can mean, for example, mechanically attached (e.g., bolted, welded, bonded, etc.), integrally formed with (e.g., cast), machined such as from a common block of material (e.g., CNC machined), additively and/or subtractively formed (e.g., 3D printed or fabricated), etc.

    (28) Certain embodiments relate to seating systems utilizing specially-configured floor tracks, seats, and other components to provide tiered seating and corresponding tiered footrests particularly on substantially flat (i.e., non-sloped) floors. Floor tracks are generally configured to sit directly on a floor or other surface (and can be mechanically attached to the floor or surface if necessary or desirable) and can be configured to support one, two, or more rows of seats. Where multiple rows are supported, the rows can be placed at predetermined distances apart from one another. Importantly, the height of each row above the floor track is independently adjustable so that tiered seating arrangements can be created, even on a flat floor. Thus, the system is adjustable as to such things as number of rows, depth of rows, distance between rows, and row elevations.

    (29) Floor tracks have been used before in seating systems, including a floor track and seating system patented in U.S. Pat. No. 8,733,838 and a floor rail system described in U.S. Pat. No. 1,931,289, each of which is hereby incorporated herein by reference.

    (30) One potential issue with tiered seating is that, as the height of a row is increased, it may become difficult or impossible for a user to rest their feet on the floor or may generally be uncomfortable, which may lead to the seating being uncomfortable for some users. Therefore, in certain embodiments, the floor tracks also can provide supports for one or more footrests for each row. The footrest(s) may be made of any appropriate material or combination of materials (e.g., metal, plastic, fabric, rubber, etc.). The footrest(s) may be adjustable-height such that, when a particular row is raised or lowered, the corresponding footrest(s) for that row also can be raised or lowered. The footrest(s) additionally or alternative could be adjustable in depth and/or angle such as to improve comfort.

    (31) Also, an important safety consideration in a track-based seating system is that the seating system generally must meet certain requirements (e.g., bylaws or other regulations) for space between rows, e.g., to ensure that users can ingress and egress without undue hardship and also to ensure that there are no tripping hazards. In certain embodiments, the footrest(s) are configured to allow for safe ingress and egress.

    (32) FIG. 1 is a schematic top view diagram of a two-row seating system formed using four floor tracks 102, in accordance with certain exemplary embodiments. Generally speaking, each pair of adjacent floor tracks supports a set of one or more seats, which generally will be interconnected in one way or another. Thus, for example, each set of one or more seats can be provided as a partially- or fully-assembled seating module configured to fit between two floor tracks set a predetermined distance apart. In FIG. 1, there are three-seat modules (e.g., seats 1-2-3 and seats 4-5-6 in each row) and there are two-seat modules (e.g., seats 7-8 in each row), although the present invention is not limited to any particular number or configuration of seats. In FIG. 1, the floor tracks 102 are configured to support two rows of seats, although the present invention is not limited to any particular number of rows (e.g., one, two, three, four, or more rows).

    (33) FIG. 2 is a schematic side view of the two-row seating system of FIG. 1. As shown, this floor track 102 is configured to support two rows of seats.

    (34) For each row, the floor track 102 preferably includes a floor track seat support base 104 attached to the floor track 102 and a floor track seat support 106 attached to the floor track seat support base 104. A seat module having one or more seats includes a seat support 114 configured to be secured to the floor track seat support 106 by a height adjusting/locking mechanism 112 allowing the seating of the seat module to be selectively raised and lowered relative to the floor track 102 as needed. It should be noted that the seat support 114 can be any appropriate seat support having elements that fit into or onto or otherwise can attach to the floor track seat support 106, e.g., the seat support 114 may include a section of round or square tubing to which the seat(s) are directly or indirectly attached (e.g., bolted or welded onto the tubing) and that extends between two floor tracks and includes vertical end portions that fit into or onto or otherwise can attach to the floor track seat support 106, although other configurations are certainly possible, and the present invention is not limited to any particular type of seating, seat support, seat module, etc. It should be noted that the present invention is not limited to any particular height adjusting/locking mechanism 112. For example, the height adjusting/locking mechanism 112 could include a bolt or other fastener that passes through holes in the seat support 114 and floor track seat support 106 or even could include different size/height inserts that are placed in the floor track seat support 106 prior to insertion of the seat support 114 (e.g., a 1 insert, a 2 insert, a 3 insert, a 4 insert, a 5 insert, etc.).

    (35) In the example shown in FIG. 2, the front row is raised by 2 relative to a nominal height and the back row is raised by 5 relative to the nominal height (i.e., 3 higher than the front row). Because the back row is raised 5 above nominal, the users of the back row seating may be unable to rest their feet on the ground or otherwise might find it uncomfortable to sit in the seats. Therefore, the floor track 102 preferably also includes one or more floor track footrest supports 108 for supporting an adjustable-height footrest 110. The floor track footrest support(s) 108 may be attached directly to the floor track 102, to the floor track seat support base 104 (sometimes referred to herein as a combination seat/footrest support 1004 that attaches to the floor track 102, for example, as depicted schematically in FIG. 16 and shown in FIGS. 5-7), to a separate footrest support base that attaches to the floor track 102, to the floor track seat support 106, or elsewhere, although it should be noted that, in any case, the footrest(s) 110 are preferably positioned such that they do not impede ingress or egress of users within the row of seating (e.g., the footrests 110) may be tucked in below the front row of seats in order to allow sufficient floor space for ingress and egress without causing a tripping hazard. It should be noted that floor track footrest support(s) 108 may be omitted from certain rows, e.g., if no additional footrest is needed or when the seating arrangement does not readily accommodate footrests for the row (e.g., at a first row of a venue with no seating in front of it). The footrest 110 includes a footrest support 111 configured to be secured to the floor track footrest support 108 by a height adjusting/locking mechanism 109 allowing the footrest 110 to be selectively raised and lowered relative to the floor track 102 as needed. It should be noted that the footrest support 111 can be any appropriate footrest support having elements that fit into or onto or otherwise can attach to the floor track footrest support 108, e.g., the footrest support 111 may include a section of round or square tubing to which the footrest 110 is directly or indirectly attached (or in some cases the footrest support 111 may be the footrest 110 itself) and that extends between two floor tracks and includes vertical end portions that fit into or onto or otherwise can attach to the floor track footrest support 108, although other configurations are certainly possible, and the present invention is not limited to any particular type of footrest or footrest support. It should be noted that the present invention is not limited to any particular height adjusting/locking mechanism 109. For example, the height adjusting/locking mechanism 109 could include a bolt or other fastener that passes through holes in the floor track footrest support 108 and footrest support 111 or even could include different size/height inserts that are placed in the floor track footrest support 108 prior to insertion of the footrest support 111 (e.g., a 1 insert, a 2 insert, a 3 insert, a 4 insert, a 5 insert, etc.). The footrest(s) additionally or alternative could be adjustable in depth (e.g., having different connection points on the floor track, or being connected to the footrest support 108 using an adjustable mechanism) and/or angled such as to improve comfort. As depicted schematically in FIG. 1, footrests can be individual footrests (e.g., two footrests per seat), can be single seat width footrests 406, or can span multiple seats widths 408. As shown, some footrests supports and/or footrests may be positioned between floor tracks and thus the footrest supports 108 additionally or alternatively may be attached to other structures, e.g., to the seats or seat supports.

    (36) It should be noted that floor track seat supports 106 and footrest supports 108 could be provided in multiple heights to provide additional flexibility in configuring tiered seating. It also should be noted that the height adjusting/locking mechanism 112 and the height adjusting/locking mechanism 109 may use the same type of height adjusting/locking mechanism or may use different types of height adjusting/locking mechanisms. It also should be noted that various alternative embodiments may omit the floor track seat support 106 and instead attach components directly to the floor track 102.

    (37) It is contemplated that certain embodiments will include additional convenience features such as a side cupholder 116 (which may be placed on a separate arm that can rotate up and down) or a seatback cupholder 118 (which may store within the seatback and allow for opening and closing of the cupholder 118). One or both of the cupholders 116 and 118 may additionally or alternatively include a tray.

    (38) FIG. 3 is a schematic side view of some additional seating configurations consistent with this disclosure including a first configuration in which one floor track supports one row of seating and the other floor track supports three rows of seating (top view of FIG. 3), a second configuration in which the floor track supports three rows of seats (middle view of FIG. 3), and a third configuration in which the floor track supports four rows of seating (bottom view of FIG. 3). Of course, other configurations are possible.

    (39) It should be noted that, in some cases, a single floor track will support two adjacent seat modules in the same row (e.g., the floor track between seats 3-4 and the floor track between seats 6-7 shown in FIG. 1 each support two adjacent seat modules). Thus, for example and without limitation, the floor track seat support 106 may be configured to accommodate two seat supports 114, or the floor track 102 may include two floor track seat supports 106 adjacent to one another, or other arrangement may be included to support two adjacent seat modules (e.g., attaching the two adjacent seat modules to a common central seat support 114).

    (40) In order to further provide space between the two rows, the seats are preferably flip-up seats and the seat bottoms are preferably biased to flip up into a closed position when the seat is vacant. In this way, the seat bottoms of unused seats can automatically move out of the way of a user as they pass through an empty row.

    (41) It should be noted that the seats and seating system may include other features, e.g., cup holders (e.g., on fixed or movable seat arms or elsewhere), seatback trays, coat/purse hooks, adjustable seat backs, seat warmers, etc.

    (42) In various alternative embodiments, the floor track system may support a platform for use as a raised walking surface. Such a platform may be particularly useful for rows in which the seats are raised significantly, e.g., by 5 or more. The platform could be installed using the existing footrest supports, for example, as depicted schematically by platform 402 in FIG. 4. In this way, the platform could be height-adjustable along with the seat heights, and footrests could be provided in other ways such as on top of the platform. However, the platform could be supported in other ways, e.g., directly on the floor tracks, for example, as depicted schematically by platform 404 in FIG. 4.

    (43) FIG. 5 is a photograph showing three rows of seating including footrest support and footrests for the second and third rows adjusted in height corresponding to the heights of the second and third row seats in accordance with certain embodiments.

    (44) FIG. 6 is a photograph showing another view of the seating shown in FIG. 5.

    (45) FIG. 7 is a photograph showing another three rows of seating including footrest support and footrests for the second and third rows adjusted in height corresponding to the heights of the second and third row seats in accordance with certain embodiments.

    (46) FIG. 8 shows the space behind the back row of seating created by the top of the backrest in substantial vertical alignment with the edge of the walkway in accordance with certain embodiments.

    (47) In addition to, or in lieu of, having footrests, embodiments could include a platform to provide a raised floor for a row of seating. The platform could rest on or between floor tracks.

    (48) FIG. 9 is a schematic diagram of a platform 902 including two optional handholds on each end of the platform to facilitate moving and positioning the platform in accordance with certain embodiments.

    (49) FIG. 10 is a schematic diagram showing a detailed view of the platform 902 of FIG. 9 positioned within a row of seating and resting on the floor track, in accordance with certain embodiments. This embodiment includes a combination seat/platform support 1002 that attaches to the floor track and supports the platform 902 and also provides floor track seat supports 106 for two rows of seating.

    (67) The indefinite articles a and an, as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean at least one.

    (68) The phrase and/or, as used herein in the specification and in the claims, should be understood to mean either or both of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with and/or should be construed in the same fashion, i.e., one or more of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the and/or clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to A and/or B, when used in conjunction with open-ended language such as comprising can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

    (69) As used herein in the specification and in the claims, or should be understood to have the same meaning as and/or as defined above. For example, when separating items in a list, or or and/or shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as only one of or exactly one of, or, when used in the claims, consisting of, will refer to the inclusion of exactly one element of a number or list of elements. In general, the term or as used herein shall only be interpreted as indicating exclusive alternatives (i.e., one or the other but not both) when preceded by terms of exclusivity, such as either, one of, only one of, or exactly one of. Consisting essentially of, when used in the claims, shall have its ordinary meaning as used in the field of patent law.

    (70) As used herein in the specification and in the claims, the phrase at least one, in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase at least one refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, at least one of A and B (or, equivalently, at least one of A or B, or, equivalently at least one of A and/or B) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

    (71) As used herein in the specification and in the claims, all transitional phrases such as comprising, including, carrying, having, containing, involving, holding, composed of, and the like are to be understood to be open-ended, i.e., to mean including but not limited to. Only the transitional phrases consisting of and consisting essentially of shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures, Section 2111.03.

    (72) Although the above discussion discloses various exemplary embodiments of the invention, it should be apparent that those skilled in the art can make various modifications that will achieve some of the advantages of the invention without departing from the true scope of the invention. Any references to the invention are intended to refer to exemplary embodiments of the invention and should not be construed to refer to all embodiments of the invention unless the context otherwise requires. The described embodiments are to be considered in all respects only as illustrative and not restrictive.
