Retractable seat assembly
View Patent ↗A retractable seat assembly which can be attached to a vertical structure and which, in the upright position, presents a profile which is relatively thin and in any event poses virtually no impediment to going very close to the vertical structure. The retractable seat assembly having a rear support, a seat, a front support, and a biaser which releasably biases said seat to the generally upright position.
1. A retractable seat assembly for attaching to a generally vertical structure, comprising:
a frame, said frame including a lowermost support portion and a connection portion;
a seat pivotally connected to said frame at said connection portion;
a biaser operatively connected to said seat and said frame to releasably bias said seat to a generally upright position;
a front support pivotally connected to said seat distal said connection portion, wherein when said seat is in said generally upright position, said front support and said seat are in planes parallel to one another; and
at least one generally L-shaped hook connected to and projecting from said frame below said seat, said at least one hook having a leg portion laterally spaced from said frame, said at least one hook defining a receiving space between said frame and said leg portion, whereby said seat assembly can be releasably attached to a portion of said vertical structure by receipt of a portion of said vertical structure in said receiving space between said leg portion and said frame.
2. The assembly of claim 1 , wherein said biaser comprises at least one torsion spring.
3. The assembly of claim 1 , wherein said biaser comprises a plurality of torsion springs.
4. The assembly of claim 1 , wherein said frame has a plurality of generally L-shaped hooks connected to and projecting from said frame.
5. The assembly of claim 1 , wherein said at least one hook is pivotally attached to said frame.
6. The assembly of claim 1 further comprising a stop attached to said seat for limiting the pivotal movement of said front support.
7. The assembly of claim 1 further comprising an adjustable strap for attaching said frame to said generally vertical structure.
8. The assembly of claim 1 further comprising brackets around said frame for affixing said frame to said generally vertical structure.
9. The assembly of claim 1 further comprising at least one pivoting arm connecting said frame and said front support.
10. A retractable seat assembly for attaching to a generally vertical mesh structure formed at least partly from mesh, comprising:
a frame, said frame including a lowermost support portion and a connection portion;
a seat pivotally connected to said frame at said connection portion;
a biaser operatively connected to said seat and said frame to releasably bias said seat to a generally upright position;
a front support pivotally connected to said seat distal said connection portion, wherein when said seat is in said generally upright position, said front support and said seat are in planes parallel to one another; and
at least one generally L-shaped hook connected to and projecting from said frame below said seat, said at least one hook having a leg portion laterally spaced from said frame, said at least one hook defining a receiving space between said frame and said leg portion, whereby said seat assembly can be releasably attached to a portion of said vertical mesh structure by downward movement of said leg through an opening in said mesh such that a portion of said vertical mesh structure is received in said receiving space between said leg portion and said frame.
