Roll-in push cart
View Patent ↗Embodiments of a roll-in push cot may comprise a support frame comprising a pair of lateral sides extending between a front end and a rear end, and a pair of slidable tracks disposed in the lateral sides; a pair of leading legs and a pair of trailing legs pivotally connected to the support frame; a front carriage member slidingly disposed within the pair of slidable tracks at the front end of the support frame, and a mechanical loading system coupled to the support frame and connecting the pair of leading legs with the pair of trailing legs, wherein the mechanical loading system comprises a front actuator disposed on the support frame in the motion path defined by the front carriage member, such that movement of the front carriage member triggers the front actuator and thereby initiates the release of the trailing legs.
1. A roll-in push cot comprising:
a support frame comprising a pair of lateral sides extending between a front end and a rear end, and a pair of slidable tracks disposed in the lateral sides;
a pair of leading legs and a pair of trailing legs pivotally connected to the support frame;
a front carriage member slidingly disposed within the pair of slidable tracks at the front end of the support frame, wherein the sliding motion of the front carriage member defines a motion path;
a rear carriage member slidingly coupled to pair of slidable tracks at the rear end of the support frame and a reset actuator disposed on the support frame in a motion path defined by the rear carriage member such that movement of the rear carriage member in conjunction with the folding of the trailing legs triggers the reset actuator, the triggering of the reset actuator being configured to lock the roll in cot when the trailing and leading legs of the cot are in a folded position;
a pair of front hinge members pivotally connected to the pair of leading legs at one end of the pair of front hinge members and slidingly connected to the front carriage member at an opposite end of the pair of front hinge members, wherein loading of the cot onto a first surface folds the pair of front hinge members and triggers the sliding of the front carriage member along the motion path; and
a mechanical loading system coupled to the support frame and connecting the pair of leading legs with the pair of trailing legs, wherein the mechanical loading system comprises a front actuator disposed on the support frame in the motion path defined by the front carriage member, such that movement of the front carriage member triggers the front actuator and thereby initiates the release of the trailing legs.
2. The cot of claim 1 , wherein the mechanical loading system comprises a middle release lever coupled to the front actuator, such that triggering the front actuator releases the middle release lever.
3. The cot of claim 1 , wherein the rear carriage member comprises a bracket with curved projections, and wherein the mechanical loading system comprises a latch pin, the latch pin being configured to lock the trailing legs by forming an interference fit with the curved projections of the rear carriage member bracket.
4. The cot of claim 3 , wherein the interference fit between the latch pin and the bracket is disengaged by an operator supporting a portion of the weight of the roll in cot, the disengagement of the latch pin triggering the release of the trailing legs.
5. The cot of claim 1 , further comprising a central support beam extending between the front end and the rear end and disposed between the pair of slidable tracks.
6. The cot of claim 1 , further comprising at least one load wheel disposed at the front end of the support frame.
7. The cot of claim 6 , further comprising a swivel lock release lever disposed at the front end of the support frame, whereby the swivel lock release lever unlocks the at least one front load wheel to allow swivel motion.
8. The cot of claim 1 , further comprising at least one intermediate load wheel disposed on the support frame between the leading and trailing legs.
9. The cot of claim 1 , further comprising at least one load wheel disposed at the rear end of the support frame.
10. The cot of claim 9 , further comprising a swivel lock release lever disposed at the rear end of the support frame, whereby the swivel lock release lever unlocks the at least one rear load wheel to allow swivel motion.
11. The cot of claim 1 , further comprising a front leg control handle disposed at the front end of the support frame, whereby the leg control handle disengages a locking mechanism that allows the folding of the leading legs.
12. The cot of claim 1 , further comprising a rear leg control handle disposed at the rear end of the support frame, whereby the leg control handle disengages a locking mechanism that allows the folding of the trailing legs.
13. The cot of claim 1 , further comprising a front leg lock switch disposed at the front end of the support frame, whereby the leg lock switch engages a locking mechanism to lock the leading legs in a folded position.
14. The cot of claim 1 , further comprising a rear leg lock switch disposed at the rear end of the support frame, whereby the leg lock switch engages a locking mechanism to lock the trailing legs in a folded position.
15. The cot of claim 1 , further comprising a release handle disposed at the rear end of the support frame, whereby the release handle allows for a stretcher to be removed from the cot.
16. The cot of claim 1 , further comprising a pair of slam latches mechanically fitted to a linkage component coupled to the pair of lateral sides, wherein the latches secure a stretcher to the cot.
17. A roll-in push cot comprising:
a support frame comprising a pair of lateral sides extending between a front end and a rear end, and a pair of slidable tracks disposed in the lateral sides;
a pair of leading legs and a pair of trailing legs pivotally connected to the support frame;
a front carriage member slidingly disposed within the pair of slidable tracks at the front end of the support frame, wherein the sliding motion of the front carriage member defines a motion path;
a pair of front hinge members pivotally connected to the pair of leading legs at one end of the pair of front hinge members and slidingly connected to the front carriage member at an opposite end of the pair of front hinge members, wherein loading of the cot onto a first surface collapses the pair of front hinge members and triggers the sliding of the front carriage member along the front carriage member motion path;
a rear carriage member slidingly coupled to pair of slidable tracks at the rear end of the support frame, wherein the sliding motion of the rear carriage member defines a motion path;
a pair of rear hinge members pivotally connected to the pair of trailing legs at one end of the pair of rear hinge members and slidingly connected to the rear carriage member at an opposite end of the pair of rear hinge members, wherein loading of the cot onto a first surface folds the pair of rear hinge members and triggers the sliding of the rear carriage member along the rear carriage member motion path; and
a mechanical loading system coupled to the support frame and connecting the pair of leading legs with the pair of trailing legs, wherein the mechanical loading system comprises
a front actuator disposed on the support frame in the motion path defined by the front carriage member,
a middle release lever coupled to the front actuator, wherein movement of the front carriage member triggers the front actuator and pulls the middle release lever,
a latch pin configured to lock the trailing legs by engaging the rear carriage member, wherein the latch pin is disengaged by an operator supporting a portion of the weight of the roll-in cot, and
a reset actuator disposed on the support frame in the rear carriage member motion path such that movement of the rear carriage member triggers the reset actuator, the triggering of the reset actuator being configured to lock the roll in cot when the trailing and leading legs of the cot are in a folded position.
