Swing with a folding back that automatically locks the swing
A swing assembly has a seat with a folding back that locks the swing automatically when the back folds from an upright configuration to a flat configuration so the swing is stable. The swing assembly includes an upper cross bar having two ends, a lower cross bar having two ends and a lateral support attached to each end of the upper cross bar and the lower cross bar, respectively. The swing assembly has a seat with two ends and a back. The back foldably attaches to the seat. A pair of seat supports attached to each end of the seat and moveably attach to a hanging support mounted on the upper cross bar adjacent each lateral support. A lower back support hangs from the seat back to automatically aligns with and lock with the lower cross bar when the swing moves from the upright configuration to the flat configuration.
1. A swing assembly having a seat with a folding back comprising:
an upper cross bar having two ends and two hanging support hooks proximate to each end;
a lower cross bar having two ends and two back support connectors proximate to each end;
a lateral support attached to each end of the upper cross bar and the lower cross bar, respectively;
a seat hanging from the upper cross bar and having two ends and a backrest, the backrest foldably attaches to the seat;
a pair of upper back supports each having first ends attached to one of the hanging support hooks and second ends removably attached to each end of the backrest to hold the backrest in an upright configuration; and
the backrest of the seat includes a lower back support rotatably attached to the second ends of the pair of upper back supports at each end of the backrest and is foldable to a flat configuration wherein the lower back support locks the seat to the back support connectors of the lower cross bar to prevent swinging movement when the pair of upper back supports are detached from each end of the backrest.
2. A swing assembly as set forth in claim 1 , wherein
the lower back support hangs from the backrest of the seat when the backrest is in the upright configuration.
3. A swing assembly as set forth in claim 2 further comprising a pair of multi support connectors each attached to an end of the backrest, an end of the lower back supports, and an end of the upper back supports, the connector including a bolt and a compression bushing.
4. A swing assembly as set forth in claim 3 , wherein the two back support connectors attached proximate to each end of the lower cross bar have a “C” shape with a channel for automatically receiving the lower back support when the backrest of the seat folds into the flat configuration.
5. A swing assembly as set forth in claim 4 , wherein the back support connector has a rounded joint to better enable the channel to automatically receive the lower back support.
6. A swing assembly as set forth in claim 5 , wherein each upper back support is a strip living an end defining holes for enabling the upper back support and seat support to moveably hang on the upper cross bar, the upper cross bar has hooks, and the ends of the upper back support hangs on the hooks.
7. A swing assembly as set forth in claim 6 , wherein each upper back support includes a lock to normally lock each upper back support to the multi support connector attached to the backrest.
8. A swing assembly as set forth in claim 7 , wherein each lock includes a spring and a pivot with an axis, the pivot is axially moveable so that pulling the pivot along the axis compresses the spring to enable the lock to pivot and release the upper back support from the multi support connector.
9. A swing assembly having a canopy and a seat with a folding backrest comprising:
an upper cross bar having a canopy and two ends;
a lower cross bar having two ends;
a lateral support attached to each end of the upper cross bar and the lower cross bar, respectively;
a seat having two ends and a backrest, the backrest foldably attaches to the seat;
a pair of seat supports attached to each end of the seat;
a hanging support mounted on the upper cross bar adjacent each lateral support;
each seat support moveably attaches to the hanging support to enable the seat to swing; and
a lower back support hanging from the backrest of the seat, the lower back support automatically locks against the lower cross bar when the backrest of the seat is foldable to a flat configuration to prevent swinging movement of the seat,
wherein the lower cross bar has a back support connector;
wherein the back support connector has a “C” shape with a channel for automatically receiving the lower back support when the backrest of the seat folds into the flat configuration;
wherein the hanging support includes opposing hooks; and
wherein an upper back support having a first end is movably attached to an opposing hook of the hanging support and having a second end is removeably attached to the backrest of the seat for holding the backrest of the seat in an upright configuration.
10. A swing assembly as set forth in claim 9 further comprising a multi support connector each attached to an end of the backrest, an end of the lower back supports, and an end of the upper back supports, the connector including a bolt and a compression bushing.
11. A swing assembly as set forth in claim 10 , wherein the upper back support and seat supports are strips having ends defining holes for enabling the upper back support and seat support to hang on the hooks.
12. A swing assembly as set forth in claim 11 , wherein each upper back support includes a lock to normally lock each upper back support to the multi support connector or the backrest.
13. A swing assembly as set forth in claim 12 , wherein each lock includes a spring and a pivot with an axis, pulling the pivot along the axis compresses the spring to enable the lock to pivot and release the upper back support from the multi support connector of the backrest.
