a closing mechanism comprising a pivot cam and a closing bar;
the pivot cam configured to be coupled to a hinge of the door using a hinge pin and coupled to the base plate using a tension member;
the closing bar linearly movable and biasingly connected to the base plate and adapted to be releasably held in place via a pawl of a lever member;
the closing mechanism coupled to the base plate and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein
in the unprimed state the closing mechanism is decoupled from operation of the door; and
in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal;
the closing bar including a plurality of gear teeth each adapted to releasably retain the pawl between any two of the plurality of gear teeth.
2. The apparatus of claim 1 , wherein the transition between the unprimed state and primed state provides a feedback to the user.
3. The apparatus of claim 1 , wherein the closing bar including a plurality of gear teeth each adapted to releasably retain the pawl between any two of the plurality of the gear teeth.
4. The apparatus of claim 1 , wherein the closing mechanism comprises a motor or solenoid.
5. The apparatus of claim 1 , wherein the closing mechanism is configured to move the door into the closed position at least in part by exerting a stored energy within the closing mechanism onto the tension member.
6. The apparatus of claim 1 , wherein the closing mechanism comprises a biasing member pivotally coupled with the lever member and the closing bar.
7. The apparatus of claim 1 , wherein the closing mechanism is positioned within the hinge of the door.
8. The apparatus of claim 1 , wherein the closing mechanism is configured to receive the signal from at least one of the following: a smoke detector, a temperature detector, a carbon monoxide detector, a home alarm system, a mobile device, or a smarthome hub.
9. The apparatus of claim 1 , wherein the closing mechanism comprises a receiver configured to receive the signal and a processor configured to trigger the closing mechanism to move the door into the closed position.
10. A door closing apparatus comprising:
a base plate configured to be coupled to a door, the door configured to be positioned in an open position and a closed position; and
a closing mechanism comprising a pivot cam, a closing bar and a cable;
the pivot cam is configured to be coupled to a hinge of the door using a hinge pin and coupled to the base plate using a tension member;
the closing bar is linearly movable and biasingly connected to the base plate and adapted to be releasably held in place via a pawl of a lever member;
the cable is connected at a distal end to the pivot cam and is connected at a proximal end to the closing bar, wherein when the door is pivoted into the open position the cable partially wraps around the pivot cam to move the closing bar;
the closing mechanism coupled to the base plate and having an unprimed state and a primed state, the closing mechanism configured to be transitioned between the unprimed state and the primed state by a user; wherein
in the unprimed state the closing mechanism is decoupled from operation of the door; and
in the primed state the closing mechanism is configured to move the door into the closed position responsive to receipt of a signal, and the closing mechanism is configured to allow movement of the door between the open position and the closed position in absence of the signal;
the closing bar including a plurality of gear teeth each adapted to releasably retain the pawl between any two of the plurality of the gear teeth.
11. The door closing apparatus of claim 10 , wherein the closing mechanism comprises a motor or solenoid.
12. The door closing apparatus of claim 10 , further comprising a motor including a plunger member connected to the lever member, wherein the plunger member is adapted to pivot the lever member so as move the pawl out from in between the any two of the plurality of gear teeth of the closing bar.
13. The door closing apparatus of claim 12 , wherein the motor is connected to the base plate.
14. The door closing apparatus of claim 10 , wherein the tension member is coupled to the frame of the door.
15. The door closing apparatus of claim 10 , wherein the closing mechanism is configured to receive the signal from at least one of the following: a smoke detector, a temperature detector, a carbon monoxide detector, a home alarm system, a mobile device, or a smarthome hub.
16. The door closing apparatus of claim 10 , wherein the closing mechanism comprises a receiver configured to receive the signal and a processor configured to trigger the closing mechanism to move the door into the closed position.
17. The door closing apparatus of claim 10 , wherein the closing mechanism is configured to move the door into the closed position at least in part by exerting a stored energy within the closing mechanism onto the tension member.
18. The door closing apparatus of claim 10 , wherein the door closing apparatus is configured to be positioned adjacent the door.
