in the following description , for purposes of explanation and not limitation , specific details are set forth in order to provide a thorough understanding of the present invention . however , it will be apparent to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details . in other instances , detailed descriptions of well - known methods and devices are omitted so as to not obscure the description of the present invention with unnecessary detail . fig1 is a perspective view of a swing 10 with seating for up to four persons . swing 10 comprises a stationary support structure 100 and a movable subframe 200 . subframe 200 is suspended from support frame 100 by means of pivot assembly 120 . support structure 100 comprises a pair of uprights 102 attached to stabilizing legs 104 . the uprights 102 are joined together at their upper ends by transverse beam 106 . legs 104 provide a stabilizing base for swing 10 . the legs may comprise arcuate numbers as shown or may be bent into a shape of straight segments . the legs may also comprise straight horizontal members that rest on the supporting surface . subframe 200 comprises a member 202 bent into a generally ovoid shape . a bearing 204 is disposed at the top of the subframe and is carried by pivot assembly 120 . seats 206 are mounted on the subframe . as shown here , a pair of seats are mounted in a facing relationship . seats 206 may be individual seats or may each be wide enough to accommodate two persons . it should be observed that the structural member 202 of subframe 200 does not encroach within the seating area . the seats are mounted such that member 202 is disposed entirely behind and entirely below the seats in the proximity thereof . the absence of structural members intruding into the seating area makes access to the seats easier and contributes to a more pleasant recreational experience . ingress and egress are further assisted by handles 110 mounted on support uprights 102 . seats 206 are disposed on subframe 200 so that the occupants can rest their feet on the ground when the swing is stationary . this provides a more comfortable seating position when the occupants desire to remain stationary . furthermore , such a seating position allows the swing to be easily propelled by use of the occupants &# 39 ; feet since their feet can remain on the ground while swinging . this is important since a rigidly suspended pendular motion swing can not be easily put into motion with the “ pumping ” action commonly used to propel a chain - suspended swing . support structure 100 and subframe 200 are preferably constructed of steel tubing for strength , durability and economy . however , other materials , such as aluminum or fiberglass , may be used if desired . seats 206 may be constructed as wooden benches or may be molded with a suitable plastic material . seats 206 may be either cushioned or uncushioned . a table 210 may be provided as an optional feature . table 210 may be mounted to subframe member 202 with an appropriate fitting so that it can be easily removed by the user , if desired . a canopy frame 130 may also be included as an optional feature . another embodiment of a swing constructed in accordance with the present invention is illustrated in fig2 . swing 30 is substantially similar to the previously described swing 10 . in this case , however , only a single seat 306 is provided . subframe 300 comprises an arcuate member 302 , which is essentially one half of the subframe member 202 in the previously described embodiment . indeed , subframe member 302 may be designed so that two of them may be joined to a lower center section ( not shown ) to provide a closed loop subframe 202 . yet another embodiment of a swing constructed in accordance with the present invention is illustrated in fig3 . swing 40 differs from the previously described embodiments in that subframe 400 is oriented transversely rather than longitudinally . the support structure is identical to that previously described . subframe 400 comprises a primary subframe 402 in the shape of a loop and a secondary , longitudinal subframe 404 that supports seats 406 . it will be recognized that the above - described invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the disclosure . thus , it is understood that the invention is not to be limited by the foregoing illustrative details , but rather is to be defined by the appended claims .
a swing has a fixed support structure and a rigid subframe suspended therefrom . the subframe is suspended on a single pivot axis , thereby permitting pendular motion below the support structure . seats are mounted on the subframe to provide side - by - side and / or face - to - face seating . the subframe is configured to arc around behind the seats rather than intrude into the space between the seats .
