Abstract: A knob device for vehicle includes a knob unit and a locking unit. The knob unit includes a rotating cover with an open end, a rotary shaft mounted to the open end, and a motor fixed to the rotating cover for driving the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and latching teeth formed at a periphery of the main body and distributed in a ring around a central axis of the rotary wheel, a gap being defined between two neighboring teeth, an iron core configured to be inserted into the gap to limit rotation of the rotary wheel, and a solenoid connected to the iron core for driving the iron core to move. The knob device can realize locking of the rotary wheel clockwise and counter-clockwise, meeting requirement of diverse use.

Abstract: A portable chemical oxygen generator for delivering oxygen to a patient is described. The generator includes a housing containing a reaction chamber. Within the reaction chamber is a quantity of a peroxide adduct. A valve is provided with a lower portion of the valve in fluid communication with the reaction chamber. An upper portion of the valve is in fluid communication with a reservoir that holds a quantity of an aqueous solution. An internal chamber is formed within the valve by releasable seals that separate the internal chamber from the upper portion of the valve and a lower portion of the valve. The internal chamber holds a quantity of a peroxide-decomposing catalyst. The generator also includes a valve actuator. Operation of the valve actuator releases the seals in the valve and creates a fluid path from the reservoir through the internal chamber into the reaction chamber.

Abstract: The present disclosure provides a knob device for vehicle which includes a knob unit and a locking unit. The knob unit includes a rotating cover, a rotary shaft and a motor configured to drive the rotating cover to vibrate. The locking unit includes a rotary wheel which includes a main body fixed to the rotary shaft and locking teeth formed at a periphery of the main body. The locking tooth includes a first end, a second end and a surface connecting the first end and the second end. A distance between the first end and the central axis of the rotary wheel is greater than a distance between the second end and the central axis. The locking unit further includes a locking pole configured to abut the first end to limit rotation of the rotary wheel clockwise, and an actuator configured to drive the locking pole to move.

Abstract: An inside door handle device includes: a handle base (10) fixed to an inner panel that composes a door interior of an automobile; an opening portion (11) formed of a through hole formed on one side of the handle base (10); an operation recessed portion (12) that has a recessed shape and is arranged adjacent to the opening portion (11) on the other side of the handle base (10); fixation portions (17) formed in the operation recessed portion (12) and fixed to the inner panel; a handle body (20) in which a grip portion (22) located on a tip end side is urged and held onto the operation recessed portion (12) while a base end side is being swingably supported on the opening portion (11) with handle support portions (14a) interposed therebetween; and a support beam (13) protruded on the opening portion (11) and formed into a fixed-fixed beam shape bent into an L-shape.

Abstract: A door handle assembly for attachment to an escutcheon, the assembly comprising a door handle, wear washer, spindle nut, spindle nut retainer, and shaft retainer. The door handle has a hub, externally threaded for engagement with the internal threads of the spindle nut, with a central hole and axial slots engaging locking tabs of the spindle nut retainer. The wear washer is inserted over the hub between the inside surface of the escutcheon and the spindle nut. The spindle nut is adjusted on the hub until the proper fit and feel is achieved. The spindle nut retainer is placed over the spindle nut to lock it in position, and a shaft retainer is placed over the spindle nut retainer to secure it. The spindle nut provides more contact surface area with the underlying wear washer, reducing cyclic wear, increasing product life, reliability and security.

Abstract: A door lock with an improved structure is disclosed. It has a turning device that includes a positioning base. The positioning base is mounted with a circular spacer with a lock control device therein. A connecting shaft for driving the lock control device is provided with a limiting element that has a protruded stopping part at its end. The lock has a lock core whose one end allows the insertion and turning of a key. Its other end is connected with the connecting shaft and has grooves, so that the stopping part of the limiting element blocks the lock core when the door is locked.

Abstract: A door handle attachment fixture for pivotally attaching a door handle to an existing escutcheon, comprising a door handle with protruding hub for insertion through an escutcheon, a wear washer, a spindle nut, a spindle nut retainer, and a shaft retainer. The hub is externally threaded for engagement with the internal threads of the spindle nut, and has a central, longitudinal hole and axial slots. The axial slots engage with locking tabs of the spindle nut retainer. The wear washer is inserted over the hub between the inside surface of the escutcheon and the spindle nut. The spindle nut is adjusted on the hub until the proper fit and feel is achieved. Once adjusted, the spindle nut retainer is placed over the spindle nut to lock it in position, and a shaft retainer is placed over the spindle nut retainer to secure it. The spindle nut provides more contact surface area with the underlying wear washer, and this reduces cyclic wear and increases product life and reliability.

Abstract: An automotive vehicle door (10) has a door lock mechanism (18) mounted therein which is mechanically operated by a door lock button assembly (24) between a lock position and an open position. The door lock button assembly (24) has a control rod (28) connected on one end (32) to the door lock mechanism (18) and is non-threadingly retained on the other end (34) to a button member (26) so as to permit the control rod (28) to pendulumingly swing a predetermined angle (.beta.) with respect to the longitudinal axis (50) thereof and to allow the button member (26) to rotate around the longitudinal axis (50) so as to prevent binding when moving through an opening (45) in a trim panel (12) of the vehicle door (10).

Abstract: A safety knob for preventing unauthorized persons, such as small children, from operating the knobs in a given direction; but enabling even the unauthorized persons to operate the knob in the opposite direction.
