Abstract
A linkage for an articulating bed comprises a first latch arm which extends from the knee section of an articulating bed. A latch bar is connected between the first latch arm and the back section of the articulating bed. The latch bar is displaceable between a first position and a second position. The latch arm is engageable with the latch bar when the latch bar is in the first position to maintain movement of the back section independent relative to the knee section. The latch arm is engageable with the latch bar when the latch bar is in the second position to interconnect the back section and the knee section.
Claims16
A linkage for an articulating bed including a mattress frame, a back section, a knee section, and an actuator for effecting movement of said back section, said linkage comprising:
- a first latch arm extending from the knee section;
- and
- a latch bar connected between said first latch arm and the back section, said latch bar being displaceable between a first position and a second position, said latch arm being engageable with said latch bar when said latch bar is in the first position to maintain movement of the back section independent relative to the knee section, said latch arm being engageable with said latch bar when said latch bar is in the second position to interconnect the back section and the knee section.
An articulating bed comprising:
- a mattress frame;
- a mattress support comprising a back section and a knee section, said back section and said knee section each including a torsion tube pivotally supported by said mattress support and a lever arm extending from said torsion tube;
- an actuator extending between said mattress frame and said back section lever arm for effecting movement of said back section;
- and
- a linkage comprising:
- a first latch arm having an upper end connected to said knee section proximate said knee section torsion tube;
- and
- a second latch arm extending from said back section torsion tube;
- and
- a downwardly extending latch bar having an upper end pivotally connected to said second latch arm and a lower end slidably and pivotally connected to said first latch arm, said latch bar being displaceable between a first position and a second position, said first latch arm being engageable with said latch bar when said latch bar is in the first position to maintain movement of said back section independent relative to said knee section, said first latch arm being engageable with said latch bar when said latch bar is in the second position to interconnect said back section and said knee section.
