Rapid attach and release clamps
View Patent ↗Rapid attach and release clamps for attaching to supports include a threaded rod, an arm pivotally attached to the threaded rod, and a knob having an exterior surface and an interior surface. The knob defines a passageway sized to fit the threaded rod. A lock comprises at least one thread and is rotatably attached to the interior surface of the knob. The lock is constructed and arranged to move between a closed position with the thread entering the passageway and engaging the threaded rod and an open position with the thread not entering the passageway. A lever is moveably attached to the clamp and constructed and arranged to rotate the lock about a pivot point.
1. A medical device clamp comprising:
a threaded rod;
an arm pivotally attached to the threaded rod; and
a knob including:
(i) an exterior surface and an interior surface defining a passageway, the threaded rod extending through the passageway;
(ii) a lock including a threaded or toothed portion, the lock rotatably attached to the interior surface of the knob, the lock constructed and arranged to move between a closed position with the threaded or toothed portion engaging the threaded rod and an open position with the threaded or toothed portion not engaging the threaded rod; and
(iii) a lever moveably attached to the knob and constructed and arranged to rotate the lock from the closed position to the open position.
2. The medical device clamp of claim 1 further comprising at least one spring constructed and arranged to press the lock into the closed position.
3. The medical device clamp of claim 1 , wherein the exterior surface of the knob includes at least one of a gripping handle and a circular base, the gripping handle having an S-shape for gripping and turning the knob.
4. A medical device pole clamp comprising:
a threaded rod;
an arm attached to the rod; and
a knob including:
(i) an exterior surface and an interior surface defining a passageway, the threaded rod extendable through the passageway;
(ii) a lock having a threaded or toothed portion, the lock being rotatably attached via a pivot to the interior surface of the knob, the lock in communication with one side of a lever, and
(iii) a lever spring-loaded to move the threaded or toothed portion into engagement with the threaded rod, the lever constructed and arranged to rotate the threaded or toothed portion about the pivot and away from the rod via a manual force applied to the lever.
5. The medical device pole clamp of claim 4 , wherein the exterior surface of the knob includes at least one of a gripping handle and a circular base, the gripping handle having an S-shape for grasping and turning the knob.
6. The medical device pole clamp of claim 4 , wherein the arm is attached to a base plate, the arm and the base plate configured to clamp about a pole to support a medical device.
7. The medical device pole clamp of claim 6 , the base plate configured to be coupled to the medical device.
8. The medical device pole clamp of claim 6 , wherein the base plate includes a channel shaped to clamp to the pole to support the medical device.
9. The medical device pole clamp of claim 6 , the arm including a first limb attached pivotally to a second limb, the second limb attached to the base plate, the first limb moved by the knob to clamp the pole between the first limb and the base plate.
10. The medical device pole clamp of claim 6 , wherein at least one of the arm and the base plate includes high coefficient of friction material to engage the pole frictionally.
11. A medical device pole clamp comprising:
a threaded rod;
an arm attached to the rod; and
a knob including:
(i) an exterior surface and an interior surface defining a passageway, the threaded rod extendable through the passageway;
(ii) a lock having a threaded or toothed portion, the lock being rotatably attached via a pivot to the interior surface of the knob, the lock in communication with one side of a lever,
(iii) a lever spring-loaded to move the threaded or toothed portion into engagement with the threaded rod, the lever constructed and arranged to rotate the threaded or toothed portion about the pivot and away from the rod via a manual force applied to the lever; and
(iv) a platform defining a bore, the lever moveable slideably within the bore.
12. The medical device pole clamp of claim 11 , the lever including a stud portion that moves slideably within the bore.
13. A medical device pole clamp comprising:
a threaded rod;
an arm attached to the rod; and
a knob including:
(i) an exterior surface and an interior surface defining a passageway, the threaded rod extendable through the passageway;
(ii) a lock having a threaded or toothed portion, the lock being rotatably attached via a pivot to the interior surface of the knob, the lock in communication with one side of a lever, wherein the lock defines a beveled edge to aid the threaded or toothed portion in being rotated away from the rod, and
(iii) a lever spring-loaded to move the threaded or toothed portion into engagement with the threaded rod, the lever constructed and arranged to rotate the threaded or toothed portion about the pivot and away from the rod via a manual force applied to the lever.
