发明名称 Child safety restraint system for swing sets
摘要 A safety system for restraining a child in a conventional swing set comprising a belt for secure placement around the upper torso of a child, with safety snap hooks attached to the belt for securely engaging the vertical support elements of the swing set. The safety snap hooks are attached to the belt by means of D-rings through which the belt passes. The D-rings are fixed at such a location as to position the safety snap hooks adjacent to the vertical support members of the swing set. Further, such D-rings are fixed at such a spacing as to prevent fastening the belt at a diameter smaller than a child's head to prevent entrapment about the neck or head. The safety snap hooks are connected to the D-rings by one or more chain or S-links, or short flexible elements. The safety snap hooks are of the type that have a self-positioning member at the hook opening that will not allow the hook to become disengaged from the vertical support elements of the swing set unless intentionally activated manually. The safety snap hooks are constructed in shape and size so they can be hooked into chain links of the vertical support elements of the swing set or fastened over the outside of chain links so as not to be movable to an adjacent chain link unless intentionally manually disengaged. The ability to be fastened over the outside of a chain link allows the safety snap hook to accommodate chain with plastic sheathing or other coverings. The safety hooks will also work on swing sets with vertical support members of rope or other flexible material by tying a knot at the appropriate location and attaching the safety hook just above the knot.
