Publication number: 20200061410Abstract: An exercise device includes a base, a first platform and a second platform. Both platforms move between a forward position and a rearward position along each own path relative to the base. The exercise device includes a flexible member operatively coupled with the first and second platforms. Furthermore, a resistance mechanism is coupled with the flexible member and configured to resist movement of at least one of the first platform and the second platform. The resistance mechanism includes a disc positioned parallel to the base and is configured to allow the disc to rotate relative to a vertical axis of the base. In addition, the flexible member is configured to allow the disc to rotate reciprocally in response to movement of the first platform or second platform.Type: ApplicationFiled: March 14, 2018Publication date: February 27, 2020Inventors: Mark D. HILDEBRANDT, Daniel KOESTER

Patent number: 9088081Abstract: A system for sealing a building electrical outlet of the type mounted within a wall surface of the building having one or more electrical plug sockets adapted to receive an electrical plug and a cover plate. The system includes two primary components. A gasket formed of an elastomeric material is provided with a pair of electrical terminal slots. A plug cover element forms a front cover panel and includes a pair of tabs extending from a back of the face surface to engage the electrical plug socket terminal slots. Two modes of operation are available. When an electrical plug is inserted into the electrical plug socket, the gasket is positioned between the plug and the socket to seal against air infiltration. When an electrical plug is not inserted into the socket, the plug cover is used to maintain the gasket in position for sealing against the electrical plug socket.Type: GrantFiled: June 7, 2013Date of Patent: July 21, 2015Assignee: SUNVENTRIXInventor: Mark D. Hildebrandt

Patent number: 5356356Abstract: A recumbent exercise device which provides lower body, upper body and cardiovascular conditioning. The device includes a frame having a seat supported toward the rear thereof. A pair of leg assemblies and a pair of arm assemblies are pivotally supported by the frame for movement about a transverse pivot axis. The arm and leg assemblies are positioned generally toward the forward end of the frame and each includes an upward and forward extending lever with the leg assemblies terminating in pedals and the arm assemblies terminating in handles. The arm and leg assemblies are connected to each other for contralateral movement. A resistance mechanism is coupled to the arm and leg assemblies to provide resistance to their movement the pivot axis. An open area is defined above the frame between the seat and the arm and leg assemblies to permit step-through access to the seat regardless of the arm and leg assembly positions.Type: GrantFiled: June 2, 1993Date of Patent: October 18, 1994Assignee: Life Plus IncorporatedInventors: Mark D.
