DETAILED DESCRIPTION OF THE INVENTION

(17) This patent application claims priority from U.S. Provisional Patent Application No. 63/068,443, filed Aug. 21, 2020, the disclosure of which is incorporated by reference herein in its entirety.

(18) Various embodiments serve to provide a chair at the balcony 101 with an integrated front rail socket 109 (see FIG. 11). This design is versatile enough to allow for a wide range of transition heights and to allow for rails 106 to be installed without the need to remove chair assemblies. FIG. 3 shows a modified telescopic seating 302 with a balcony mount chair (or balcony mount nose mounted chair) 307 installed on the balcony 101 in an extended (FIG. 3A) and closed (FIG. 3B) configuration. FIG. 3 as an example of a section of seating that utilizes a balcony mounted chair 307 and integrated rail socket 109 solution.

(19) Some embodiments include telescopic seating structures 302 that transition to a balcony 101 or require seating on a surface that is not suitable for conventional attachment methods such as heavily damaged surfaces. These systems are typically installed in school gymnasiums, theaters, arenas or stadiums, but not limited to these venues.

(20) In one non-limiting embodiment, the balcony mounted chair with integrated rail socket solution is comprised of three main components: the balcony mount beam 113, the balcony mount stanchion 127, and the front rail socket 109. This solution can be fully seen in FIGS. 12-14. FIG. 12 shows an isometric view of a row of balcony mount nose mounted chairs 307 in the used position. FIG. 13 shows an isometric view of a row of balcony mount nose mounted chairs 307 in the stored position. FIG. 14 shows side views of a balcony mounted chair 307 with a front rail 106 removed and the seats ready for use (FIG. 14A) and with the front rail 106 in use (FIG. 14B). Each of these components have aspects of their design that ensure that any balcony construction, chair size, or transition can use this solution.

(21) FIG. 10 shows details of the beam 113 design that the balcony mount chair/rail solution is attached to. The beam 113 is designed using a heavy gauge front plate 128 to take most of the live loads of the chair and an optional (application dependent) thinner top plate 129 to share the load and help prevent any twist from occurring in the beam 113 when under load. The design utilizes an attachment on the front 130 and top 131 faces of the balcony 101 to ensure that the connection between the beam 113 and the balcony 101 is rigid and produces the most stable feeling chair possible. There may be more attachment holes than are used to withstand the live loading by design. This allows for damaged areas of the balcony 101 or areas that cannot receive an attachment to be avoided during installation of the beam 113. A sectional view of the beam 113 can be seen in FIG. 10.

(22) The beam 113 is shown attached to concrete, however, in other embodiments, the beam 113 and attachment hardware can be altered to allow for attachment to other structures. It can also be seen in FIG. 10 that there is a return 133 at the bottom of the heavy front plate 128. This return has regular attachment holes in it, for example, every 2″, for the chairs to be secured into the beam 113. An isometric view of this design can be seen in FIG. 9. FIG. 9 shows a beam 113 which is designed to have attachments holes every 2″ on the return of the heavy front plate 128 to ensure that all seat size combinations can be installed on the same beam 113.

(23) FIG. 4 shows a low-rise range nose mounted chair in the used (FIG. 4A) and stored (FIG. 4B) position. The balcony mount stanchion 127 uses an unlock mechanism and folding motion.

(24) These chairs are typically constructed of three main parts: the back assembly 110, the seat assembly 111, and the stanchions 126 (commonly referred to as standards). For a nose mounted chair, the stanchions 126 are the components that will attach the chair to the platform 302 and dictate the seat height and back pitch of the chair. A stanchion is comprised of two main components: the bracket 115 and the stanchion tube 114. The bracket 115 is used to attach the stanchion 126 to the nose 112 or front beam of the platform 302 and to attach the seat 111 to the stanchion 126. The stanchion tube 114 attaches to the bracket 115 with a shaft 124 and provides an attachment location for the back assembly 110 and the armrest.

(25) FIG. 5 shows a low-rise nose mount stanchion 126 in the used (FIG. 5A) and stored (FIG. 5B) configuration and FIG. 6 shows a cut view showing how a low-rise range nose mounted stanchion 126 unlocks. The nose mount stanchion latch 125 (see FIG. 6) can be released by rotating the unlock shaft 117 allowing the back assembly 110 and stanchion tube 114 to rotate forward so the chairs can nest together when stored.

(26) FIG. 7 shows a “balcony mount” stanchion 127, both in the used (FIG. 7A) and stored (FIG. 7B) position and FIG. 8 shows a detailed cut view showing internal components of a balcony mount stanchion 127. With the balcony mount stanchion 127, the rotation of the stanchion tube 114, the back pitch, and seat height are all mirrored after the low-rise nose mounted stanchion 126. However, with the balcony mounted stanchion 127 the side plates of the bracket 115 and nose mount bracket 116 allow for the stanchion 127 to be installed to a beam 113 that is attached to the balcony 101. The side plates 122 of the bracket 118 are designed to incorporate a hook feature 120. When attached to the beam 113, the hook feature 120 operates with an upward extension of the heavy front plate 128 to secure the chair 307. This is a main structural feature for the stanchion 127 and will take a majority of the live loads of the chair. This hook feature 120 can be seen in FIG. 7 and FIG. 8.

(27) The balcony mount nose mounted chair 307 includes a balcony mount beam bracket 119 that is designed with four slots in it that are each spaced 1″ from each other. This spacing along with the 2″ spacing on the beam 113 allows for any chair size with 1″ increments to be installed on the beam 113. This bracket 119 is located a very specific distance down from the hook feature 120 so that it can create a clamping force on the beam 113 when installed. This clamping force prevents against any movement of the stanchion 127 once it has been installed on the beam 113.

(28) FIG. 11 shows an installation of the front rail socket 109 and the balcony mount stanchion 127 to the beam 113. The balcony mount stanchion 127 is designed with an integrated attachment location 121 for a front rail socket 109. The socket 109 bolts directly to the stanchion 127 through the spacers 123 with two machine screws and the socket has its own hook feature 109a. By having both an integrated attachment location 121 and a separate hook feature 109a on the socket 109, it is able to withstand the loading requirements of a full height front rail 106. The socket 109 is shaped in such a way that it doesn't interfere with any of the chair components, and it fits within the rake of the back assembly 110 of the balcony mount chair. This ensures that the socket 109 doesn't impede egress of the first row of fixed seating when the balcony mount chair 307 is in use.

(29) The exact geometry of the bracket 118 will depend on the given rise that the chair is being installed on. Having the side plates 122 and beam bracket 119 modified to keep a consistent seat height at a transition can be applied to any rise transition. FIG. 15 shows multiple rise ranges of the balcony mount stanchion 127 that have been developed using this method.

(30) The foregoing description has been directed to particular embodiments. However, other variations and modifications may be made to the described embodiments, with the attainment of some or all of their advantages. Modifications to the above-described systems and methods may be made without departing from the concepts disclosed herein. Accordingly, the invention should not be viewed as limited by the disclosed embodiments. Furthermore, various features of the described embodiments may be used without the corresponding use of other features. Thus, this description should be read as merely illustrative of various principles, and not in limitation of the invention.
