Abstract
Abstract A powered ashtray assembly (100) is disclosed for use in automobiles or similar vehicles. The ashtray assembly (100) includes a movable assembly frame (106) slidably mounted within an assembly housing (104). A manually operable switch (140) selectively applies activating signals to a motor (148) secured to frame (106). The motor (148) drives a spline (170) threaded to a stationary shaft (172) secured to a stationary frame (124). Activation of the motor (148) causes the spline (170) to be driven along the shaft (172) so as to selectively extend and retract the assembly frame (106) relative to the assembly housing (104).

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
147 words
In an ashtray assembly for use in an operator controlled vehicle having a battery source, wherein the assembly includes a stationary frame mounted within an assembly housing and an assembly frame slidably mounted to the stationary frame so as to be selectively retractable into a closed position within the housing and selectively extendable into an open position forward of the housing, the improvement which comprises: power means adapted to be connected to the battery source and mounted between the assembly frame and the stationary frame for exerting forces on the assembly frame with respect to the stationary frame so as to selectively extend and retract the assembly frame; switch means electrically coupled to the power means and responsive to selective activation by a vehicle occupant for generating activating signals; and the power means is responsive to the activating signals to exert the forces on the assembly frame.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
71 words
An ashtray assembly in accordance with claim 1 characterized in that the power means comprises: motor means mounted to the assembly frame and electrically coupled to the switch means for generating torque in response to the activating signals; and means coupled to the motor means and secured to the stationary frame and responsive to the generated torque for exerting the forces on the assembly frame with respect to the stationary frame.
Claim 4
Dependent Claim
70 words
An ashtray assembly in accordance with claim 2 characterized in that the means coupled to the motor means comprises a threaded shaft rigidly secured to the stationary frame and a spline having an internal thread engaging the threaded shaft; and the motor means comprises means for translating generated torque to rotational forces applied to the spline, thereby causing the spline to rotate and move axially relative to the threaded shaft.
Claim 5
Dependent Claim
50 words
An ashtray assembly in accordance with claim 3 characterized in that the motor means further comprises a bidirectional motor having a motor shaft perpendicular to the threaded shaft and the means for translating the generated torque comprises a worm gear secured to the motor shaft in mesh with the spline.
Claim 6
Dependent Claim
109 words
An ashtray assembly in accordance with claim 4 characterized in that the threaded shaft is positioned axially along the direction of movement of the assembly frame; angular rotation of the motor shaft in a first direction causes the spline to move axially along the threaded shaft in a manner so that forces are exerted on the assembly frame to extend the assembly frame from the stationary frame; and angular rotation of the motor shaft in a reverse direction causes the spline to move axially along the threaded shaft in a manner so that forces are exerted on the assembly frame to retract the assembly frame into the assembly housing.
Claim 7
Dependent Claim
103 words
An ashtray assembly in accordance with claim 4 characterized in that: the assembly frame comprises an upper horizontal plate member; the motor means further comprises a motor housing rigidly secured to an underside of the upper member; the motor is mounted within the motor housing and the motor shaft extends therefrom; the threaded shaft extends through apertures in a pair of vertical brackets connected to the underside of the upper member; and a pair of collar and sleeve assemblies are journalled on the threaded shaft and extend through the apertures of the vertical brackets, and the spline is positioned between the vertical brackets.
Claim 8
Dependent Claim
63 words
An ashtray assembly in accordance with claim 2 characterized in that the assembly frame comprises: a front plate having the switch means mounted thereon; a pair of vertical side members connected to the front plate and extending rearward therefrom; and an upper plate member connected to each of the vertical side members and having the motor means mounted to a lower surface thereof.
Claim 9
Dependent Claim
70 words
An ashtray assembly in accordance with claim 7 characterized in that the assembly further comprises second switch means positioned between the assembly frame and the stationary frame for detecting approach of the assembly frame to the open or closed position and for generating deactivating signals in response thereto; and the motor means is connected to the second switch means and responsive to the deactivating signals for ceasing generation of torque.
Claim 10
Dependent Claim
72 words
An ashtray assembly in accordance with claim 8 characterized in that the second switch means comprises a first microswitch mounted on the stationary frame toward the front of the upper plate member for detecting approach of the assembly frame to the open position, and a second microswitch is mounted on the stationary frame toward the rear of the upper plate member for detecting approach of the assembly frame to the closed position.
Claim 11
Dependent Claim
39 words
An ashtray assembly in accordance with claim 9 and further comprising means for reversing the direction of angular rotation of the motor means relative to the previous direction of rotation in response to a subsequent generation of activating signals.
Claim 12
Dependent Claim
57 words
An ashtray assembly in accordance with claim 1 characterized in that the power means comprises motor means capable of angular rotation in either of two directions and responsive to a generation of the activating signals to reverse the direction of angular rotation relative to the direction of rotation responsive to an immediately prior generation of activating signals.
Claim 13
Dependent Claim
74 words
An ashtray assembly in accordance with claim 1 characterized in that the switch means comprises first and second switches selectively activated by the vehicle occupant for generating first and second sets of activating signals, respectively; and the power means comprises motor means responsive to the first set of activating signals for generating torque in a first direction and further responsive to the second set of activating signals for generating torque in a reverse direction.
Claim 14
Dependent Claim
76 words
An ashtray assembly in accordance with claim 1 characterized in that the assembly further comprises: second switch means interposed between the assembly frame and the stationary frame for detecting approach of the assembly frame to the open or closed position and for generating deactivating signals in response thereto; and the power means is further connected to the second switch means and responsive to the deactivating signals for ceasing exertion of the forces on the assembly frame.
Claim 15
Dependent Claim
61 words
An ashtray assembly in accordance with claim 13 characterized in that the second switch means comprises a first microswitch mounted towards the front of the stationary frame for detecting approach of the assembly frame to the open position, and a second microswitch mounted towards the rear of the stationary frame for detecting approach of the assembly frame to the closed position.
Claim 16
Dependent Claim
65 words
An ashtray assembly in accordance with claim 13 characterized in that the power means comprises motor means mounted on the assembly frame and capable of angular rotation in either of two directions, the motor means being responsive to the deactivating signals for reversing the direction of angular rotation relative to the immediately previous direction of rotation in response to a subsequent generation of activating signals.
