  • Publication number: 20230356976
    Abstract: Systems, apparatuses, and methods are described for a stairlift overspeed safety system are disclosed. The overspeed safety system may include a centripetal cam assembly, a trigger assembly, and a jammer assembly. The centripetal cam assembly may include a spring-loaded plate and a plurality of centripetal cams connected to the spring-loaded plate, configured to move to an extended position when the rail speed exceeds the speed threshold. The trigger assembly may include a trigger plate configured to be pushed by at least one of the centripetal cams when moved to the extended position. Pushing the trigger plate may cause a switch to open to shut off power to the motorized stairlift. The jammer assembly may include a jammer configured to wedge between teeth of a rack and pinion of the motorized stairlift to initiate a deceleration to stop movement of the motorized stairlift.

  • Patent number: 11007919
    Abstract: A pivoting system has an electronic device pivotably mounted on a cargo platform. A base is coupled to a cargo support. A linkage rod slidably engages with the cargo platform. A proximal pivot pivotably couples the proximal end of the linkage rod arm to the base. A device pivot pivotably couples the electronic device to the cargo platform. A distal pivot pivotably couples the distal end of the linkage rod to the electronic device. The pivoting system causes pivoting of the electronic device between a lower general horizontal position and an upper general horizontal position.

  • Patent number: 10453572
    Abstract: A medical cart includes a controller, display unit and display application that enables a user to select controls to specify different functions to be executed by the controller and to specify different status data to be displayed. A system for providing remote services to the medical cart includes a database and a server, both of which are located remotely from the cart. The database includes a plurality of applications. The server includes a data collection unit to collect data associated with the medical carts, and an analysis unit to analyze the collected data to detect a condition associated with the cart. In response to the detected condition, the control unit executes one or more of the applications, determines parameters to be communicated to the cart, automatically downloads one or more applications to the cart, and/or activating a web page having information to a user displaying information about the cart.

  • Patent number: 9680333
    Abstract: A power system for a medical cart includes a power supply, a direct current power bus electrically coupled to the power supply, and an electrical output power module electrically coupled to the direct current power bus. The power supply is positioned within the base of the medical cart and outputs direct current electrical power. The direct current power bus is the support of the medical cart, with the base being at one end of the support. The electrical output power module is within the work platform of the medical cart at the other end of the support. The electrical output power module inputs the direct current electrical power from the direct current power bus, and converts the input direct current electrical power to an electrical power output having a different state.

  • Patent number: 8308168
    Abstract: The quick change tool bit holder comprises a bore for receiving a bit. A retaining tooth, or plurality of teeth, is movable into engagement with the bit when the bit is inserted into the bore to retain the bit in the bore. An ejector ejects the bit from the bore when the retaining tooth is moved out of engagement with the bit. The ejector may comprise a spring that is compressed when the bit is inserted in the bore and a push button is biased by the spring into engagement with the bit. A sleeve forces the retaining tooth into engagement with the bit when said sleeve is in the locking position where the tooth moves at an angle relative to a longitudinal axis into contact with the bit. A method of operating the quick change tool bit holder is also disclosed.
