Publication number: 20230356976Abstract: 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.Type: ApplicationFiled: March 9, 2023Publication date: November 9, 2023Inventors: Robert Alexander Pratt, IV, Derek J.

Patent number: 11007919Abstract: 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.Type: GrantFiled: October 28, 2019Date of Patent: May 18, 2021Assignee: Harmar Mobility, LLCInventor: Derek J.

Patent number: 9680333Abstract: 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.Type: GrantFiled: March 15, 2013Date of Patent: June 13, 2017Assignee: CAPSA SOLUTIONS, LLCInventors: Richard Jason Brooks, Derek J.

Patent number: 8308168Abstract: 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.Type: GrantFiled: February 27, 2009Date of Patent: November 13, 2012Assignee: Irwin Industrial Tool CompanyInventor: Derek J.
