Abstract

Claims (40)

1 . A patient support apparatus comprising:

a deck;

a mattress; and

a reconfigurable mattress coupler to couple said mattress to said deck to limit or prevent migration of said mattress relative to said deck, wherein said mattress coupler includes a base and a projecting arm extending from said base, said base being attached to said mattress, said mattress coupler including a pivotal arm pivotally mounted to said projecting arm, wherein said pivotal arm is biased toward a non-compact, engaged position, such that said pivotal arm pivots toward said projecting arm in response to insertion of said mattress coupler into an opening of said deck and said pivotal arm returns to said non-compact, engaged position after insertion of said mattress coupler into said opening of said deck,

wherein said mattress coupler is reconfigurable between an engaged configuration to couple said mattress with said deck and a non-engaged configuration to release said mattress from being coupled with said deck,

wherein said mattress coupler is biased in one of said engaged or non-engaged configurations, and

wherein said mattress coupler is biased in said engaged configuration so that said pivotal arm is biased toward said non-compact, engaged position.

2 . The patient support apparatus of claim 1 , wherein said mattress includes a deck facing side, and said mattress coupler is attached to or formed on said deck facing side of said mattress.

3 . The patient support apparatus of claim 2 wherein said mattress has a cover, said mattress coupler is welded to said cover.

4 . A patient support apparatus comprising:

a deck;

a mattress; and

a reconfigurable mattress coupler to couple said mattress to said deck to limit, if not prevent, migration of said mattress relative to said deck, wherein said mattress coupler includes a base and a projecting arm extending from said base, said base being attached to said mattress, said mattress coupler including a pivotal arm pivotally mounted to said projecting arm, wherein said pivotal arm is biased toward a non-compact, engaged position, such that said pivotal arm pivots toward said projecting arm in response to insertion of said mattress coupler into an opening of said deck and said pivotal arm returns to said non-compact, engaged position after insertion of said mattress coupler into said opening of said deck,

wherein said mattress coupler is reconfigurable between an engaged configuration to couple said mattress with said deck and a non-engaged configuration to release said mattress from being coupled with said deck,

wherein said mattress coupler is biased in one of said configurations, and

wherein said non-engaged configuration of said mattress coupler being a compact configuration to facilitate insertion of said mattress coupler through said opening, and after insertion, said mattress coupler is configured to return to said engaged configuration with said pivotal arm extending away from said projecting arm to engage said deck adjacent said opening of said deck.

5 . The patient support apparatus of claim 4 , wherein said non-engaged configuration is a folded configuration for insertion of said mattress coupler into said opening.

6 . A patient support apparatus comprising:

a deck;

a mattress; and

a reconfigurable mattress coupler to couple said mattress to said deck to limit, if not prevent, migration of said mattress relative to said deck, wherein said mattress coupler includes a base and a projecting arm extending from said base, said base being attached to said mattress, said mattress coupler including a pivotal arm pivotally mounted to said projecting arm, wherein said pivotal arm is biased toward a non-compact, engaged position, such that said pivotal arm pivots toward said projecting arm in response to insertion of said mattress coupler into an opening of said deck and said pivotal arm returns to said non-compact, engaged position after insertion of said mattress coupler into said opening of said deck,

wherein said mattress coupler is reconfigurable between an engaged configuration to couple said mattress with said deck and a non-engaged configuration to release said mattress from being coupled with said deck,

wherein said mattress coupler is biased in one of said configurations,

wherein said non-engaged configuration is a folded configuration for insertion of said mattress coupler into said opening, and

wherein said pivotal arm is pivotally mounted to said projecting arm by a hinge connection.

7 . The patient support apparatus of claim 1 , wherein said pivotal arm is pivotally mounted to said projecting arm by a pivot pin or pivot pins extending into one end of said pivotal arm.

8 . A patient support apparatus comprising:

a deck;

a mattress;

a reconfigurable mattress coupler to couple said mattress to said deck to limit, if not prevent, migration of said mattress relative to said deck, wherein said mattress coupler includes a base and a projecting arm extending from said base, said base being attached to said mattress, said mattress coupler including a pivotal arm pivotally mounted to said projecting arm, wherein said pivotal arm is biased toward a non-compact, engaged position, such that said pivotal arm pivots toward said projecting arm in response to insertion of said mattress coupler into an opening of said deck and said pivotal arm returns to said non-compact, engaged position after insertion of said mattress coupler into said opening of said deck, wherein said pivotal arm is pivotally mounted to said projecting arm by a pivot pin or pivot pins extending into one end of said pivotal arm; and

a spring mounted about said pivot pin or pivot pins to form a torsional spring biasing said pivotal arm to said non-compact, engaged position.

9 . A patient support apparatus comprising:

a deck;

a mattress; and

a mattress coupler to couple said mattress to said deck to limit migration of said mattress relative to said deck, said mattress coupler including a base and a projecting arm extending from said base, said base being attached to said mattress, said mattress coupler including a pivotal arm pivotally mounted to said projecting arm, said mattress coupler operable to re-configure in response to contact with said deck during coupling between said mattress and said deck, such that said pivotal arm pivots toward said projecting arm in response to insertion of said mattress coupler into an opening of said deck and said pivotal arm returns to a non-compact, engaged position after insertion of said mattress coupler into said opening of said deck,

wherein said mattress coupler is biased in one of an engaged configuration or a non-engaged configuration, and

wherein said mattress coupler is biased in said engaged configuration so that said projecting arm is biased toward said non-compact, engaged position.

10 . The patient support apparatus of claim 9 , wherein said mattress coupler is operable to decouple from said deck in response to a user manually re-configuring said mattress coupler to fit within said opening of said deck.

11 . The patient support apparatus of claim 9 , wherein said mattress coupler is reconfigurable between said engaged configuration to couple said mattress with said deck and said non-engaged configuration to release said mattress from being coupled with said deck.

12 . The patient support apparatus of claim 9 wherein said mattress includes a deck facing side, and said mattress coupler is attached to or formed on said deck facing side of said mattress.
