Abstract
door handle (100) is configured for mounting to a door (90) and includes a shell (102) having a front side and a rear side, with the shell defining an internal chamber. A shank (126) extends from the rear side of the shell, and a light source (not shown) is seated in the internal chamber. The rear side of the shell is located between the light source and the door when the door handle is mounted to the door. A window pattern (180) is positioned on the rear side of the shell (102) such that the window pattern faces the door. The window pattern includes at least one opaque region and a plurality of transparent or translucent regions. The light source is operable to project onto the door a light pattern (190) corresponding to the window pattern (180), the light pattern including at least one dark region corresponding to the at least one opaque region, and a plurality of lighted regions (194) corresponding to the plurality of transparent or translucent regions. The proposed invention provides a door handle with a light projection system for enhancing the overall aesthetic of the door.
Claims (23)
1. A door handle configured for mounting to a door, the door handle comprising: a shell having a front side and a rear side, the shell defining an internal chamber; a shank extending from the rear side; a light source positioned in the internal chamber with the rear side of the shell located between the light source and the door when the door handle is mounted to the door; and a window pattern defined by the rear side of the shell such that the window pattern faces the door, the light source is operable to project a light pattern onto the door corresponding to the window pattern, wherein the window pattern includes at least one opaque region and a plurality of transparent or translucent regions; and wherein the light pattern includes at least one dark region corresponding to the at least one opaque region and a plurality of lighted regions corresponding to the plurality of transparent or translucent regions.
2. The door handle of claim 1, wherein the shank includes an opening sized and shaped to receive a spindle of a trim mounted to the door.
3. The door handle of claim 1, further comprising a light modulator positioned between the light source and the window pattern.
4. The door handle of claim 1, wherein the window pattern comprises a plurality of windows defined in the rear side of the shell.
5. The door handle of claim 1, wherein the window pattern is releasably mounted to the rear side of the shell.
6. The door handle of claim 1, further comprising control circuitry disposed in the chamber and a sensor array in communication with the circuitry, wherein the control circuitry is configured to activate the light source based upon information transmitted by the sensor array.
7. The door handle of claim 6, wherein the sensor array comprises an ambient light sensor, and wherein the control circuitry is configured to activate the light source based on information received from the ambient light sensor.
8. The door handle of claim 7, wherein the sensor array further comprises a motion sensor, and wherein the control circuitry is configured to activate the light source based upon information received from the motion sensor.
9. The door handle of claim 8, wherein the control circuitry is configured to activate the light source in response to the information from the ambient light source indicating that a level of ambient light is below a threshold level and the information from the motion detector indicating the presence of a user.
10. The door handle of claim 6, wherein the sensor array further comprises a motion sensor, and wherein the control circuitry is configured to activate the light source based upon information received from the motion sensor.
11. The door handle of claim 6, wherein the front side of the shell comprises an opening through which the sensor array is operable to detect an environmental condition.
12. The door handle of claim 6, wherein the front side of the shell comprises a translucent shield through which the sensor array is operable to detect an environmental condition.
13. The door handle of claim 1, wherein the window pattern is a decorative pattern.
14. The door handle of claim 1, further comprising control circuitry and a sensor array in communication with the control circuitry; wherein the sensor array comprises an ambient light sensor, and wherein the control circuitry is configured to activate the light source based on information received from the ambient light sensor; and wherein the sensor array further comprises a motion sensor, and wherein the control circuitry is configured to activate the light source based upon information received from the motion sensor.
15. An apparatus comprising the door handle of claim 1, the apparatus further comprising a trim configured for mounting to the door, the trim including a latchbolt, and wherein the door handle is mounted to the trim such that rotation of the door handle about a rotational axis defined by the shank causes retraction of the latchbolt.
16. The door handle of claim 1, wherein the varied regions include at least one opaque region and at least one transparent or translucent region.
17. The door handle of claim 16, wherein the light pattern includes at least one dark region corresponding to the at least one opaque region of the window pattern; and wherein the light pattern includes at least one lighted region corresponding to the at least one transparent or translucent region.
18. A method, comprising: removing the window pattern from the handle of claim 1; and replacing the window pattern with a second window pattern different from the window pattern.
19. The method of claim 18, further comprising passing light through a light modulator positioned between the light source and the window pattern.
20. The method of claim 19, wherein passing the light through the light modulator diffuses and/or diffracts the light.
21. The method of claim 18, further comprising sensing, with a sensor of the handle, an environmental condition; and wherein the light pattern is projected onto the door in response to the environmental condition satisfying at least one criterion.
22. The method of claim 21, wherein the environmental condition comprises an ambient light level, and wherein the at least one criterion comprises the ambient light level falling below a threshold value.
23. The method of claim 21, further comprising sensing motion with a motion sensor of the handle; and wherein the at least one criterion comprises the sensed motion.
