Actuator with time delay
First Claim
1. A product-dispensing device comprising:
- a housing;
an actuator supported by the housing for rotation about a first axis; and
a time delay mechanism operably coupled to the actuator, the time delay mechanism including a first gear, a second gear, a damper, and a biasing member, the first gear fixed for rotation with the actuator, the second gear supported by the housing for rotation about a second axis and configured to engage the first gear,wherein the first gear is operable to rotate the second gear in a first direction about the second axis, the biasing member is operable to rotate the second gear in a second direction about the second axis, and the damper is operable to control a rate of rotation of the second gear in the second direction about the second axis, the second direction being opposite the first direction, andwherein the time delay mechanism includes a signaling wheel fixed for rotation with the second gear about the second axis, the signaling wheel having a circular outer wall defining a recessed area offset from the second axis, the actuator having a protrusion operably received by the recessed area in a first mode of operation.

Abstract
A product-dispensing device includes a housing, an actuator, and a time delay mechanism. The actuator is supported by the housing for rotation about a first axis. The time delay mechanism is operably coupled to the actuator and includes a first gear, a second gear, a damper, and a biasing member. The first gear is fixed for rotation with the actuator. The second gear is supported by the housing for rotation about a second axis and configured to engage the first gear. The first gear is operable to rotate the second gear in a first direction about the second axis. The biasing member is operable to rotate the second gear in a second direction about the second axis. The damper is operable to control a rate of rotation of the second gear in the second direction about the second axis. The second direction is opposite the first direction.

15. A product-dispensing device comprising:
-
a housing having a first side and a second side opposite the first side, the first side defining an annular recess, the second side defining a recessed housing area, the housing further including an opening aligned with the annular recess and the recessed housing area; an actuator supported by the housing for rotation about a first axis, the actuator including a protrusion translatably received by the annular recess; a first gear coupled to the actuator for rotation about the first axis; a second gear operably coupled to the first gear and disposed within the recessed housing area for rotation about a second axis, the second gear including a peripheral wall defining an opening configured to receive the protrusion; a biasing member operably coupled to the second gear and configured to rotate the second gear in a first direction about the second axis; and a damper operably coupled to the second gear and configured to control a rate of rotation of the second gear in the first direction about the second axis. - View Dependent Claims (16, 17, 18)
