## Background
BACKGROUND OF THE DISCLOSURE
Field of the Disclosure
The disclosure relates to door lock devices and more particularly pertains to a new door lock device for automatically opening or closing a door for a bathroom stall.
SUMMARY OF THE DISCLOSURE
An embodiment of the disclosure meets the needs presented above by generally comprising a door having an inner edge, an outer edge, an inner surface and an outer surface. A frame includes a first vertical section and a second vertical section which are spaced from each other. The inner edge is hingedly coupled to the first vertical section. The door extends between the first and second vertical sections to define a closed position. A drive assembly is attached to the door and to the frame. The drive assembly is actuated in a first direction to move the door to the closed position and in a second direction to move the door to an open position. An outer switch is mounted on an outside surface of the frame. The outer switch is positioned on the first vertical section and is electrically coupled to a control circuit. The control circuit is electrically coupled to the drive assembly. The control circuit sends an open signal to the drive assembly to actuate the drive assembly in the second direction. An inner switch is mounted on an inside surface of the frame and positioned on the vertical section. The inner switch is electrically coupled to the control circuit. The control circuit sends a close signal to the drive assembly to actuate the drive assembly in the first direction when the door is in the open position and the inner switch is actuated. The control circuit sends the open signal to the drive assembly when the door is in the closed position and the inner switch is actuated.

There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new door lock device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the door lock system 10 generally comprises a door 12 having an inner edge 14, an outer edge 16, an inner surface 18 and an outer surface 20. A frame 22 includes a first vertical section 24 and a second vertical section 26 spaced from each other and the inner edge 14 is hingedly coupled to the first vertical section 24. The door 12 extends between the first 24 and second 26 vertical sections to define a closed position. More particularly, the door 12 may comprise a door 12 for a toilet stall wherein the frame 22 may only include the first 24 and second 26 vertical sections, though an upper section 28 may also be provided extending between the first 24 and second 26 vertical sections and which is positioned above the door 12.
A drive assembly 30 is attached to the door 12 and to the frame 22. The drive assembly 30 is actuated in a first direction to move the door 12 to the closed position and in a second direction to move the door 12 to an open position. The drive assembly 30 may be conventional to automatic door opening and closing assemblies. The drive assembly 30 may include a motor 32 which is engaged to an arm assembly 34 such that the arm assembly 34 is moved between a first position and a second position when the motor 32 is activated in a first direction or a second direction.
An outer switch 36 is mounted on an outside surface of the frame 22. The outer switch 36 is positioned on the second vertical section 26. The outer switch 36 is electrically coupled to a control circuit 38 and the control circuit 38 is electrically coupled to the drive assembly 30. The control circuit 38 sends an open signal to the drive assembly 30 to actuate the drive assembly 30 in the second direction when the outer switch 36 is actuated. An inner switch 40 is mounted on an inside surface of the frame 22 and positioned on the second vertical section 26. The inner switch 40 is electrically coupled to the control circuit 38. The control circuit 38 sends a close signal to the drive assembly 30 to actuate the drive assembly 30 in the first direction when the door is in the open position and the inner switch 40 is actuated. The control circuit 38 sends the open signal to the drive assembly 30 when the door 12 is in the closed position and the inner switch 40 is actuated. Each of the inner 40 and outer 36 switches may each comprise a sensor such as a motion sensor which detects motion within about 6.0 inches of the sensor. As can been seen in FIG. 3, the motion sensors may include a finger space 42 through which a user's finger may be moved to be detected by the motion sensors.
A latch 44 is mounted on the inside surface of the frame 22. The latch 44 is electrically driven, such as with a solenoid 46, and is electrically coupled to the control circuit 38. The latch 44 engages the door 12 when the inner switch 40 is actuated to move the door 12 to the closed position and the door 12 obtains the closed position. The latch 44 disengages the door 12 when the inner switch 40 is actuated when the door 12 is already in the closed position at the time of inner switch 40 actuation. The control circuit 38 may be programmed such that the outer switch 36 is deactivated when the latch 44 engages the door 12. Thus, when a person is within the bathroom stall, another person cannot use the outer switch 36 to open the door. Also, as can be seen from the step diagram of FIG. 5, after the door 12 has been opened, the system may cause the door 12 to again be moved to a closed, unlocked position, such that the door 12 may be opened by actuating the outer switch 36.
In use, the system 10 allows a person to open or close a close a door 12 to a bathroom stall without gripping a handle and thus more sanitarily use a toilet. The system 10 further locks the door 12 automatically when it is closed to prevent entry by another person.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
