Abstract

A folding furniture piece including: a spring mechanism including a flange; an articulated vertebral column including multiple vertebral members arranged and operatively connected via one or more connecting members to form a flexible unit including the vertebral column and an object base; a locking mechanism located on the object base; the spring mechanism exhibiting properties such that the folding furniture piece assumes an unfolded state where both the vertebral column and spring mechanism are substantially straight to provide a closed sitting surface and, in response to a bending force, assumes a folded state where both the vertebral column and spring mechanism are curved to expose the sitting surface on which an object can rest, and where, in response to the bending force, the spring mechanism travels along the object base such that the locking mechanism operatively interlocks with the flange and the folding furniture piece remains in the folded state.

First claim

What is claimed is:

1. A folding furniture piece configured for convenient storage, the folding furniture piece comprising:
a spring mechanism comprising a flange;
an articulated vertebral column comprising multiple vertebral members arranged in lengthwise parallel alignment with one another and operatively connected to one another via one or more connecting members;
the one or more connecting members configured to cooperate with the operatively connected vertebral members to form a flexible unit comprising the vertebral column and an object base;
the object base having opposite ends between which is located a sitting surface on one side and an external surface on the opposite side, one end of the object base connected to the vertebral column and the other end of the object base constituting a free end;
a locking mechanism located on the external surface of the object base; and
the spring mechanism exhibiting flexibility properties such that the folding furniture piece assumes an unfolded state in which both the vertebral column and spring mechanism are substantially straight to provide a closed sitting surface and, in response to an externally applied bending force, assumes a folded state in which both the vertebral column and spring mechanism are curved to expose the sitting surface on which an object can rest, and wherein, in response to the externally applied bending force, at least a portion of the spring mechanism travels along the external surface of the object base such that the locking mechanism operatively interlocks with the flange and causes the folding furniture piece to remain releasably locked in the folded state.

2. The folding furniture piece of claim 1 , wherein the folding furniture piece is mounted onto the back panel of a vehicle seat.

3. The folding furniture piece of claim 1 , wherein the multiple vertebral members of the articulated vertebral column are interconnected via living hinges and each vertebral member comprises chamfered sides, and wherein, in response to the externally applied bending force, the living hinges bend such that the chamfered sides of the multiple vertebral members press against each other or one end of the object base such that the vertebral column will bend and cause the folding furniture piece to assume the folded state.

4. The folding furniture piece of claim 3 , wherein the chamfered sides are at a five degree angle.

5. The folding furniture piece of claim 1 , wherein:
the locking mechanism is mounted to the external surface of the object base via a spring hinge;
the locking mechanism further comprises a stop; and
wherein the stop is configured to pass over the flange while at least a portion of the spring mechanism travels along the external surface of the object base, the stop is further configured to return to rest against the spring mechanism after passing over the flange so as to allow the locking mechanism to operatively interlock with the flange when the stop presses against one side of the flange.

6. The folding furniture piece of claim 5 , wherein the locking mechanism further comprises a handle configured to enable a user to move the stop away from resting against the surface of the spring mechanism via the spring hinge.

7. The folding furniture piece of claim 1 , wherein both the one or more connecting members and spring mechanism are flexible steel strips.

8. A folding furniture piece configured for convenient storage, the folding furniture piece comprising:
a spring mechanism comprising a plurality of spaced slots;
an articulated vertebral column comprising multiple vertebral members arranged in lengthwise parallel alignment with one another and operatively connected to one another via one or more connecting members;
the one or more connecting members configured to cooperate with the operatively connected vertebral members to form a flexible unit comprising the vertebral column and an object base;
the object base having opposite ends between which is located a sitting surface on one side and an external surface on the opposite side, one end of the object base connected to the vertebral column and the other end of the object base constituting a free end;
a locking mechanism located on the external surface of the object base; and
the spring mechanism exhibiting flexibility properties such that the folding furniture piece assumes an unfolded state in which both the vertebral column and spring mechanism are substantially straight to provide a closed sitting surface and, in response to an externally applied bending force, assumes an adjustably folded state in which both the vertebral column and spring mechanism are curved to expose the sitting surface on which an object can rest, and wherein, in response to the externally applied bending force, at least a portion of the spring mechanism travels along the external surface of the object base such that the locking mechanism operatively interlocks with one of the slots in the plurality of slots and causes the folding furniture piece to remain releasably locked in the adjustably folded state.

9. The folding furniture piece of claim 8 , wherein the folding furniture piece is mounted onto the back panel of a vehicle seat.

10. The folding furniture piece of claim 8 , wherein the multiple vertebral members of the articulated vertebral column are interconnected via living hinges and each vertebral member comprises chamfered sides, and wherein, in response to the externally applied bending force, the living hinges bend such that the chamfered sides of the multiple vertebral members press against each other or one end of the object base such that the vertebral column will bend and cause the folding furniture piece to assume the folded state.

11. The folding furniture piece of claim 10 , wherein the chamfered sides are at a five degree angle.

12. The folding furniture piece of claim 8 , wherein:
the locking mechanism is mounted to the external surface of the object base via a spring hinge;
the locking mechanism further comprises a stop;
each slot in the plurality of slots comprises a tapered side and a flat side; and
wherein the stop is configured to pass over each slot via the tapered side until the stop can return to rest in a selected slot of the plurality slots while at least a portion of the spring mechanism travels along the external surface of the object base, the stop is further configured to return to rest in the selected slot so as to allow the locking mechanism to operatively interlock with the selected slot when the stop presses against the flat side of the selected slot.

13. The folding furniture piece of claim 12 , wherein the locking mechanism further comprises a handle configured to enable a user to move the stop away from resting against the surface of the spring mechanism or within a selected slot via the spring hinge.

14. The folding furniture piece of claim 8 , wherein both the one or more connecting members and spring mechanism are flexible steel strips.

15. A method of installing a folding furniture piece onto a surface, the method comprising:
providing a folding furniture piece configured for convenient storage, the folding furniture piece comprising:
a spring mechanism comprising a flange;
an articulated vertebral column comprising multiple vertebral members arranged in lengthwise parallel alignment with one another and operatively connected to one another via one or more connecting members;
the one or more connecting members configured to cooperate with the operatively connected vertebral members to form a flexible unit comprising the vertebral column and an object base;
the obj
