A swinger's position elevatory swing is disclosed. The swing lets manual and mechanical elevation of swinger's position by swinger's feet or hands at about the highest position of the swinger and thereby increasing the swinging times due to increased potential energy of the sitting board loaded with the swinger. A fixed sitting board is fixed to the swing ropes and has an arcuate hollow guide pipe and a fixing pipe. A movable sitting board is coupled to the fixed board and has an arcuate slide bar, engaging with the guide pipe of the fixed board, and a support bar. The support bar is pivoted to the fixing pipe of the fixed board by a pivot pin. The length ratio of the opposed portions of the support bar about its moment action point is about 2:3.
A swing having a stationary support member to which is pivotally attached to first and second arms. The first and second arms are in turn pivotally attached by connectors on side wings that extend from a base member. The base member has an arcuate surface that extends from a first end to a second end with the side wings extending on a tangent from the second end for a fixed distance to a terminus point. The center of gravity of the attached base member is selected such that the base member is in an approximate horizontal plane with the first and second arms in a rest position. A person mounts the base member to define a prone position with their hands on a handle adjacent the first end and feet located on a support attached to the terminus point of the side wings. As the person propels the base member in an arc about a first pivot of the first and second arms and stationary support, the base member pivots rotates in a counter manner on yokes which attached the side wings. The first and second ends of the base member remain in a substantially proportional and equal distances from a ground lines as the base member sequentially moves through parallel and horizontal planes with respect to the ground line to give the person a sensation of speed.
A system for orienting or biasing swings before installation uses a device having a bed adjusted to the desired orientation or bias. The swing is supported from a temporary support by its normal semi-elastic supports which are stretched in a manner to conform to the bias of the bed. In order to obtain the necessary amount of stretching in the semi-elastic support, the swing is forced into the bed during a process in which the bed is moved vertically to facilitate the stretching of the semi-elastic supports.
A ropeboard apparatus includes a ropeboard, and a support rope for hanging the ropeboard from an elevated structure. The ropeboard comprises an elongated platform having a longitudinal platform axis and a top surface shaped for a user to stand thereon, and a coupler for rotatably coupling the platform to the support rope so that the platform can be rotated about its longitudinal axis. The ropeboard apparatus may also include a spunk or universal joint for attaching the support rope to the structure, and a handle attached to the support rope at a location above the ropeboard. The coupler may comprise a shaft rigidly connected to the platform and oriented along the longitudinal axis, and a connector rotatably coupled to the shaft for connecting the platform to the support rope. The subject ropeboard apparatus is a new recreational and sporting apparatus that facilitates the performance of an extreme sport involving stunts and tricks.
