Abstract:
A cooking appliance (5) includes an outer cabinet (15) within which is provided an oven cavity (10) which can be selectively accessed by movement of a door (25) mounted through a door linkage system (75, 85, 90, 100, 120, 125) which enables the door (25) to be shifted between opened and closed positions through either sliding or tilting movements. In particular, the door (25) can be automatically or manually shifted between open and closed positions, through either the sliding or tilting motions. In accordance with another aspect of the invention, the door (25) can be automatically opened at the end of a process or cooking cycle, or manually opened.
Abstract:
The present invention provides for apparatus and methods for operating a garage door. An embodiment of an operating assembly for a door includes a shaft, a graduated drum, and an energy storing member. The shaft is coupled to the door such that the shaft rotates in a first direction as the door is opened and rotates in a second direction as the door is closed. The coupling of the shaft to the door is typically accomplished by a cable. The graduated drum is coupled to the shaft and the energy storing member is coupled to the graduated drum by another cable. The energy storing member is arranged such that the energy storing member stores energy as the door is closed and releases stored energy as the door is opened to assist in the raising and lowering of the door.
Abstract:
A power closing assembly operates a closure panel hingedly secured to a motor vehicle. The power closing assembly includes an actuator mounted to the motor vehicle, a movable striker also mounted to the motor vehicle to receive the closure panel's latch, and a rotary power cable connecting therebetween. The actuator has a closure cable on a spooling drum extending to the closure panel for closing from an open position when the actuator operates. The movable striker moves between a nominal inboard position and an outboard position. A rotary power cable connects between a provided output on the actuator and an input on the striker so that the striker's movement is powered and synchronized by the actuator. With the closure panel open, the actuator begins a closing cycle by driving in a direction to spool in the closure cable extending to the closure panel. The actuator's direction, using the rotary power cable, simultaneously causes the striker to move outboard. When the closure panel is pulled completely closed, the striker has also moved to its outboard position whereupon the closure panel's latch readily receives and engages the striker. Upon engagement the actuator reverses its drive direction. This reverse direction causes both the actuator to reset with respect to its closure cable spooling drum and the rotary power cable to turn in the other direction causing the striker to return to its inboard position and fully close the closure panel against its seal load.
Abstract:
A resistance mechanism suitable for applications such as resistance exercise equipment, cable reels, garage doors and other equipment requiring a resistive force. Resistance packs (26) include circular rims (28) and central hubs (30) connected by deformable spokes (32). The packs (26) are stacked in pairs with the rims (28) in each pair pinned together and the hubs (30) ratatable relative to one another. Each hub has a spline (34) connection with the hub of the next resistance pack in the adjacent pair. This provides a series arrangement of the resistance packs (26) which allows a long extension of the actuator with the spokes (32) of each pack being deformed only slightly. A spiral pay out pulley for the cord assists in avoiding varying resistance with extersion of the cord. The mechanism includes a preload system for applying a preload force to the resistance packs and a visual indicator for indicating the level of the preload force. An alternative construction involves forming the resistance packs in a single base having a pair of the resistance devices housed together. The devices may include arms connected by peripheral portions to provide loops that are looped around walls on the base to avoid a need for a bonded connection of the arms to the rims.
Abstract:
A power-operated system (32) for actuating the rear doors or liftgates (18) of motor vehicles (10) is disclosed. The system includes a strut assembly having two struts (30), each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut (30) is connected to a powered moving arm (40). To open the door, the arms (40) move to change the angular orientation of the struts (30) such that they have a substantial mechanical advantage. In this position, the force provided by the struts (30) overcomes the weight bias of the door (18), thus opening the door. To close the door, the moving arms (30) change the angular orientation of the struts (30) such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore allowing the door (18) to fall closed under its own weight bias. A control system for controlling the power-operated system (32) is also disclosed.
Abstract:
The gate has an exchangeable span (4) that is fixed to the load bearing beam (3) and is connected with pulley bearings (11) and rope-slings (12) to the system of adjustable counterweights (9). The drive system is fitted with an electric drive (19) with a worm-wheel (24) mounted to the load bearing beam (3) that travels vertically along the worm (22). The beam, span and the drive travel on adjustable guiderails (2) inside a reinforced concrete pit (1) in the direction opposite to that of counterweights (9). The load bearing beam (3) is fitted with rollers (5) and retaining rollers mounted to the cover (18). Emergency (manual) operation of the gate is possible by turning a crank handle connected with the worm (22), having released the lock that prevents the worm from rotating on its axis.
Abstract:
The invention relates to an apparatus for balancing an object (1) to be reciprocated in a vertical plane along a circular orbit, which apparatus comprises at least a frame part (2) and a pivot shaft (8) pivoted to the frame part (2), to which pivot shaft the object (1) to be moved is fixed, and which apparatus comprises at least a compensating means (9) that balances the changing force exerted by the weight of the object (1) to be moved. The apparatus also comprises at least means (4-6) that convert the moment produced by the compensating means (9) and transmit it to the pivot shaft (8) of the object (1) to be moved.
Abstract:
Hinge for rocker door of a cabinet provided with a structure (11 ), said hinge comprising a support frame (30) fixed to the structure (11) of the cabinet (10) and defining a door hinge element (31 ); a retaining rod (40) having an anterior end (41) fixed to the door (20) and a posterior end (42) positioned on the interior of the structure (11 ) of the cabinet (10); and one spring (50) interconnecting the posterior end (42) of the retaining rod (40) with the structure (11 ) of the cabinet (10), in order to force the door (20) constantly to a closed position. The structure (11) of the cabinet (10) fixes an elastically deformable stop (15), the retaining rod (40) carrying a protuberance (45) which interferes with the stop (15) to elastically yield it in a respective displacement portion of the door (20) and to retain the latter one in a partial opening position, against the force of the spring (50).

Abstract:
A dish washer (1), wherein springs (33) used for raising and lowering a door are stored in the columns (6) of a washer body. Since the springs (33) are closed in the columns (6), the aesthetic appearance of the dish washer is improved while a measure for waterproofing the springs (33) is taken. Also, since a space between the right and left side columns (6, 6) can be used as a washing chamber, the size of the washing chamber can be increased. As a result, the dish washer can be reduced in size while maintaining the volume of the washing chamber.
