There are generally two types of swings that are known for use with swing sets or with other playground installations and/or is a residential setting: (i) conventional rectangular rigid swing seats or flexible strap-like swing seats meant to move on an arc in a back-and-forth motion; or (ii) tire swings that use a vehicle tire or like structure and that can twist and swing in any direction such as diagonal, circular, etc. These prior swings require the child or other user to pump his or her legs or otherwise shift their weight to move the swing, and require the user to maintain a sitting position and hold onto the swing or the rope(s) or chain(s) by which the swing is suspended. As such, these known swings have been found to have limited entertainment and enjoyment for certain children and other users that are not capable of maintaining the proper position on the swing and/or that are not capable of controlling the motion of the swing in the manner intended and required.
Furthermore, these prior swings and others have been found to be deficient for a wide variety of other reasons including ease of manufacture, ease of installation, ease of use, durability, variety of modes of operation, safety, and other such attributes. As such, a need has been found for a new and improved swing.
In accordance with one aspect of the present development, a swing includes a body including a concave central portion defining a recessed seat and a peripheral edge surrounding the concave central portion. The peripheral edge includes a plurality of tether openings, and each of the tether openings is adapted to receive a flexible swing support member.
In accordance with a further aspect of the present development, the peripheral edge of said body is circular such that said body defines a circular disk.
In accordance with another aspect of the present development, the peripheral edge includes at least four of the tether openings arranged symmetrically about the peripheral edge such that the four tether openings are circumferentially spaced at 90 degree intervals from each other and such that each of the four tether openings are diametrically opposed from another one of the four tether openings.
In accordance with a further aspect of the present development, the seat includes a drain opening defined therein.
In accordance with an additional aspect of the present development, the drain opening is centrally located in the seat so as to be equidistant from each of the four tether openings.
In accordance with one aspect of the present development, the body is defined as a one-piece molded polymeric construction.
In accordance with another aspect of the present development, the body is defined from multiple interconnected body member sections.
In accordance with another aspect of the present development, an upper surface of said seat is smooth and a lower surface of the seat comprises a plurality of ribs extending therefrom.
In accordance with one aspect of the present development, the ribs comprise a plurality of radial ribs, each of which extends radially outward from an inner end located adjacent the drain opening.
In accordance with another aspect of the present development, each of the radial ribs is oriented normal to said lower surface of said seat.
In accordance with a further aspect of the present development, the peripheral edge comprises a top wall that extends radially outward from the seat, an outer circular wall connected to and projecting downwardly from an outer end of the top wall, and an inner circular wall connected to and projecting downwardly from an inner end of the top wall such that the inner circular wall is located radially inward from and is arranged concentrically with the outer circular wall and a peripheral groove is defined between the inner and outer circular walls, wherein the tether openings are defined in the top wall and open through the top wall into the peripheral groove.
In accordance with another aspect of the present development, a plurality of peripheral edge support ribs each extend between and interconnect the inner and outer circular walls.
In accordance with one aspect of the present development, the peripheral groove includes first and second open regions that are free of said peripheral edge support ribs, wherein the first open region is located between first and second ones of the tether openings, and wherein the second open region is located between third and fourth ones of the tether openings.
In accordance with another aspect of the present development, the swing further comprises a tether system including a lower portion including a plurality of flexible tethers engaged with the tether openings and an upper portion including one or more flexible tethers adapted to suspend the swing from a support member.
In one embodiment, the recessed central seat portion comprises fabric or another flexible material.
In accordance with another embodiment, the body includes a ballast chamber including a ballast material therein.
The peripheral edge 12 of the body B includes a plurality of tether openings O1, O2, O3, O4 with which the lower tethers LT1-LT4 are respectively engaged. In the illustrated embodiment, the peripheral edge 12 comprises at least four of the tether openings O1-O4 arranged symmetrically about the peripheral edge 12 such that the four tether openings O1-O4 are circumferentially spaced at 90 degree intervals from each other and such that each of said four tether openings are diametrically opposed from another one of the four tether openings.
The concave central seat portion 10 includes a drain opening D defined therein for allowing water and dirt/sand to flow by gravity from the seat recess R through the drain opening D. The drain opening D is centrally located in the central seat portion 10 so as to be equidistant from each of said four tether openings O1-O4 and so as to be located at the deepest part of the recess R.
An upper surface US of the concave central seat portion 10 is smooth for maximum comfort and to facilitate flow or water and sand toward the drain opening D. The opposite lower surface LS of the concave central seat portion 10 comprises a plurality of seat support ribs 30 extending or projecting therefrom. In the illustrated embodiment, the seat support ribs 30 are radial ribs, each of which extends radially outward from an inner end located adjacent the drain opening D to an outer end located adjacent the peripheral edge 12. Each of the seat support radial ribs 30 is oriented normal to said lower surface LS.
The peripheral edge 12 comprises: (i) a top wall 12a that extends radially outward from the outermost edge of the seat recess R; (ii) an outer circular wall 12b connected to and projecting downwardly from an outer end of the top wall 12a; and, (iii) an inner circular wall 12c connected to and projecting downwardly from an inner end of the top wall 12a such that the inner circular wall 12c is located radially inward from and is arranged concentrically with the outer circular wall 12b. As such, a peripheral groove 12g is defined between the outer and inner circular walls 12b,12c. The tether openings O1-O4 are each defined in the top wall 12a and each open through the top wall 12a into the peripheral groove 12g.
The body B further comprises a plurality of peripheral edge support ribs 32 that each extend between and interconnect the outer and inner circular walls 12b,12c to provide support and strength to the outer and inner circular walls 12b,12c. The peripheral edge support ribs 32 are aligned respectively with the seat support ribs 30, such that each peripheral edge support rib 32 extends in a radial direction coincident with the seat support rib 30 with which it is aligned. The peripheral groove 12g comprises first and second open regions G1, G2 that extend circumferentially and that are free of the peripheral edge support ribs 32. The first open region G1 is located between the first and second tether openings O1,O2, and the second open region G2 is located between the third and fourth tether openings O3,O4. The first open region G1 is adapted to receive the rope or chain or other member that defines the first and second lower tethers LT1, LT2 and allows the rope/chain/member thereof to extend circumferentially in the peripheral groove 12g between and through the tether openings O1,O2 in the case where the first and second lower tethers are defined from a single rope/chain/member. The second open region G2 is adapted to receive the rope or chain or other member that defines the third and fourth lower tethers LT3, LT4 and allows the rope/chain/member thereof to extend circumferentially in the peripheral groove 12g between and through the tether openings O3,O4 in the case where the third and fourth lower tethers are defined from a single rope/chain/member.
The development has been described with reference to preferred embodiments.
