CHILD'S SWING
Abstract
A swing employs a hollow U-shaped tubular frame having a top
horizontal tube. An elongated vertical tube is pivotally secured at
its upper end to the midpoint of the horizontal tube. A seat is
secured to the vertical tube, and is free to swing back and forth
below an in a vertical plane perpendicular to the horizontal tube.
A clip extends horizontally over the horizontal tube at right
angles thereto and has a spring at each end extending downwardly
and inwardly toward the vertical tube.

Claims
Having thus described this invention, what is asserted as new
is:
1. A child's swing comprising: a hollow frame having a top
horizontal member;
an elongated vertical member pivotally secured at its upper end to
the midpoint of the horizontal member and free to swing back and
forth therebelow in a vertical plane perpendicular to the
horizontal member;
a seat;
a means securing said seat to the bottom of the vertical member;
and
additional means provided with springs for engaging and for
limiting the excursions of the vertical member.
2. The swing of claim 1 wherein said additional means includes a
horizontally elongated clip secured on top of the horizontal member
at its midpoint and extending at right angles to the horizontal
member, said clip having springs oppositely disposed at opposite
ends.
3. The swing of claim 2 wherein said springs extend downward and
inward toward the vertical member.
Description
FIELD OF THE INVENTION
My invention is directed toward a child's swing requiring a minimum
effort to operate and which holds a child safely and securely.
SUMMARY OF THE INVENTION
To this end, I employ a vertical frame with an elongated horizontal
member. An elongated vertical member is pivotally secured at its
upper end to the midpoint of the horizontally disposed member and
is free to swing back and forth in a vertical plane perpendicular
to the horizontal member.
A horizontally elongated clip extends over the midpoint of the
horizontal member in a direction at right angles thereto. A
separate coil spring is secured to each end of the clip. The
springs extend downward and inward toward the vertical member.
In use, a child is disposed in a seat with means securing the seat
to the vertical member. The vertical member is then placed into
swinging motion. The excursion in each direction is limited by the
springs which are compressed upon contact and then return to normal
expanded position to enhance the swing action and reduce effort of
the operator.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a perspective of one embodiment of my invention;
FIG. 2 is a cross section thereof;
FIG. 3 is a detail of a portion of the structure; and
FIG. 4 is a detail of the seat used in the structure of FIGS. 1 and
2.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to FIGS. 1-4, parallel vertical inverted U shaped
members 10 have their vertically downward extensions bearing
against the ground 12 or other horizontal surface. The midpoint of
each horizontal portion of member 10 each supports a vertically
upwardly extending stub 14.
Vertical hollow tubes 16 open at both ends each have its bottom and
receiving stub 14 as an insert. The top end of each tube 16 is
tapered downward and inward as shown at 18 to fit into the open
bottom end of vertical hollow legs 20 of a large inverted vertical
inverted U shaped member disposed at right angles to members 10 and
extending therebetween. Legs 20 are joined by an integral
horizontally elongated element 22.
A post has a vertical section 24 pivotally disposed at its top end
about the midpoint of element 22 whereby section 24 can pivot
freely back and forth in a vertical plane disposed at right angles
to element 22.
The bottom of section 24 has a short horizontal portion which
terminates in a vertically upwardly extending tip 28 lying in the
plane.
A transversely extending horizontal clip 32 overlies the midpoint
of element 22 and has at each end a downwardly and inwardly
extending spring 30 lying in the pivot plane whereby as section 24
swings and pivots it contacts one or the other of the springs and
the direction of swing is reversed.
A seat has a bottom horizontal section 46 detachably securable at
its bottom surface to tip 28. Top and bottom sections 34 and 36 are
hingedly secured to opposite edges of section 32 and can be locked
into various positions, varying from horizontal to upward for
section 34 and varying from horizontal to downward vertical for
section 36. Thumbscrews 38 hold the structure in place. With
section 34 serving as a back and section 36 serving as a leg
support, protective sides 40 can be secured to the other edges of
section 32 and extend upward. These sides can be detached when not
needed. The inner surfaces of the seat can be upholstered, and
straps 42 can also be used as desired.
The structure so described can be used as a swing to entertain and
amuse young children. The action of the springs reduces effort and
provides a smoother swing action.
While I have described my invention with particular reference to
the drawings, such is not intended to be considered as limiting its
actual scope.
