Background

[0001] The present invention provides a new and useful door locking device, door locking assembly, and method of constructing a door locking assembly.

[0002] In the applicant's experience, a young child being able to open a door can be a dangerous condition. As an example, the front door of a home or apartment can be a particular place of worry', if a young child could unlock even a deadbolt and open the door. Thus, applicant perceived an important need for a way to secure the door in a way that a young child could not reach and unlock. In addition, when the door is an apartment door, and the tenant may risk issues with a landlord if the tenant damages the door, providing an apartment door with a way to secure the door in a way that does minimal damage to the door and still achieves applicant's basic objective of preventing a child from opening the door presented an additional challenge. In addition, with many elderly building occupants, e.g. in an assisted living environment, a nursing home environment the same types of concerns and issues can also present themselves, particularly with respect to mentally impaired residents (e.g. Alzheimer patients).

|0003] Applicant's solution to those concerns and issues have led to a new and useful way of accomplishing those objectives; i.e. provide a secure way of locking a door in a way that prevents a child or elderly person (e.g. a mentally impaired patient) from opening the door when they should not be opening it, and accomplishing that objective in a way that minimizes damage to the door structure. Applicant has provided a new and useful door locking device, door locking assembly, and method of constructing a door locking assembly that achieve those objectives.

[0004] Applicant's invention is designed to not allow children or persons with mental issues to open a hinged door and exit or enter a room or a house. The invention is also designed so as the person leaves or enters they can secure the door. The remote capability allows only persons with the activation or deactivation remote to control the lock and unlock of the device. The main entrance of the house is the primary place for this device so those persons or children are not able to get outside but the second important place is for the bathroom door adding security to the medicine cabinet. Another useful place is a closet door that contains chemicals. Unlike a deadbolt that everyone can reach even a small child on a chair the locking device of the present invention can be mounted high on the door and jamb and can be remote controlled. It gives security to a parent or family member that the person or child cannot get out of or into areas without permission to do so.

Detailed Description

As described above, the present invention relates to a new and useful structure and method of providing a secure way of locking a door in a way that prevents a child or elderly (e.g. mentally impaired) person from opening the door when they should not be opening it, and accomplishing that objective in a way that minimizes damage to the door structure. The invention is described herein in connection with a door and jamb of an apartment door, and from that description, the manner in which the principles of the present invention can be applied to various other types of door structures will be apparent to those in the art.

[0022] Referring to Figures 1-8, 10, 11, a door locking assembly 100 includes first and second subassemblies 102, 104, configured to connect to a door jamb 103 and door 105, respectively. A first locking member, in the form of a locking bar 106 forms part of the second subassembly 104 and a second locking member, in the form of a pivotal latch 108, forms part of the first subassembly 102. The first and second locking members 106. 108, are selectively engaged (the pivotal latch pivots to a position in which it overlies the locking bar) to lock the door with the jamb and selectively disengaged (by movement of the pivotal member) to unlock the door from the jamb.

[0023] The structure of the second subassembly 104, and its connection to the door 105 is designed to allow adjustment of the locking bar 106 in a plurality of directions, to enable the door locking device to be adjusted provide a predetermined locking orientation of the first and second locking members. Specifically, the locking bar 106 has a locking portion 106a, the second subassembly includes a pair of interfitiing U shaped components 110, 112 and the locking bar 106 is fastened to the U shaped component 112. Specifically, the top part 112a of the U shaped component 112 has slots 113 in which locking screws 111 are received, and allow adjustment of the locking bar in directions parallel to the surface 114 of the door. The interfitting U shaped components 110 112 have pairs of slots 115 extending perpendicular to the surface of the door, and adjustment screws 117 connected with those slots that enable adjustment of the U shaped components in directions perpendicular to the surface 114 of the door and also allow some degree of angular adjustment of the U shaped components, to thereby provide selective adjustment of the locking bar in directions perpendicular to the door surface 114 and also angular adjustment of the locking bar 106 relative to the door surface. Thus, there are effectively six points of adjustment for the locking bar 106, so that when the subassemblies 102, 104 are connected to the door jamb and door, the locking bar and the U shaped components can be selectively adjusted to adjust the position of the locking bar 106 (and particularly the locking bar portion 106a) in directions parallel to, perpendicular to, and angularly relative to the surface 114 of the door.

[0024] The first subassembly 102 comprises a housing 120 with a pair of

parallel legs 121, 123, a compartment 122 in which the pivotal latch 108 (which is servo controlled) is located, a top plate 126 on top of the compartment 122, and a cover plate 124 on top of the top plate. The cover plate 124 has a pair of legs 124a, 124b that define a slot 128 for receiving the locking bar portion 106a and allowing the locking bar portion 106a to move with the door when the locking device is unlocked and the door is being opened or closed). The pivotal latch 108 is pivotal in the slot between locking position (Figure 1 ) and an unlocking position (Figure 2). The pivotal latch 108 is spaced from the top plate 126 (e.g. by a distance D in Figures 5a, 5b) to define part of the slot 128 for receiving the locking bar portion 106a. That Distance D is close to the thickness of the locking bar portion 106a that will be received in the slot 128, so that the locking bar portion 106a of the locking bar will extend into the slot 128 and lie flat against the top plate 126 when the pivotal latch 108 is pivoted to a position in which it lies over and across the locking bar portion 106a to lock the door and the jamb. The adjustment of the locking bar 106 relative to the door, by the six points of adjustment described above, is designed to enable the locking bar portion 106a to be selectively adjusted, to accommodate different jamb configurations, and also insure that the locking bar portion 106a will fit securely in the slot 128 and against the top cover 126, so that when the pivotal latch 108 is pivoted to a locking position, it will overlie the locking bar portion 106a and lock door and jamb.

[0025] The connection of the first subassembly 102 to the door jamb 103 is designed to provide minimal, easily repaired, intrusion to the structure of the door jamb; and the connection of the second subassembly 104 to the door 105 (essentially to the inside surface 114 of the door) is of a type that connects to the door surface without damage to the door while providing a secure connection of the locking components when they are selectively engaged. Specifically, the legs 121, 123 of the housing 120 are spaced apart to accommodate a typical door jamb width, and have holes 129 through which locking screws 131 can extend to couple the first subassembly 102 to the sides of a door jamb. The use of locking screws 131 provides minimal, easily repaired intrusion to the structure of the door jamb, because all that is required is to remove the screws and spackle the screw holes.

In a preferred version of the device, a. the second subassembly 104 is connected to the inside surface 114 of the door (e.g. by an adhesive strip 132, also referred to as "mounting tape", that extends away from the U shaped housing member 110) and the locking bar 106 extends substantially parallel to the inside surface 114 of the door. The connection of the locking bar 106 to the U shaped housing member 110 allows selective adjustment of the locking bar in a direction parallel to the surface 114 of the door. The connections between the V shaped housing members 110, 112 allows selective adjustment of (he locking bar in directions perpendicular to and also angular in relation to the surface of the door, thereby providing the 6 points of adjustment of the locking bar 106 relative to the door and the first subassembly 102. b. The first subassembly 102 comprises the housing 120, the pivotal locking member Hatch) 108 connected with the housing (and located in the compartment 122 in the housing member), and a cover assembly (formed by the top plate 126 and the cover plate 124) connected with the housing member 120, covering the compartment 122) and combined with the housing to contain the pivotal latch 108. The top cover 124 has the slot 128 into which the locking bar portion 106a of the second subassembly fits in a predetermined orientation when the door is in a closed position, and the pivotal latch 108 is pivotal between a locking position (Figure 1) in which it overlies the locking bar portion 106a and prevents movement of the locking bar away from the door jamb 103, thereby to lock the door to the door jamb, and an unlocked position (Figure 2) in which the locking bar portion 106a on the second subassembly can move through the slot 128 and in a direction away from the first subassembly 102 to enable the door to be opened. c. Also, the pivotal locking member 108 is servo controlled, and the servo control of the pivotal locking member can be manually or remotely controlled (e.g. by a remote controller 170 that communicates control signals to a receiver 172 which relates those control signals to a controller 166 for a servo 164 that controls the pivotal latch 108). As shown in Figures 8, 1 la and 1 lb, the servo 164 can be located in the compartment 122 on the housing 120. As shown in the circuit diagram of Figure 8, a pair of switches 160, 162 can manually control the servo 164, so that the locking device can be manually locked when desired. As further shown in Figure 8, the switches 160, 162 can be remotely controlled, so that the locking device can be controlled from inside or outside the door.

[0027] Also, it should be noted that the locking device can be placed high enough on the door and the jamb so that it is out of reach of young children, and many elderly persons with mental conditions that make it desirable to control their access to the locking device.

[0028] Thus, the locking device of the invention is designed to minimize access to the locking device by children or persons with mental issues and thereby limits their ability to open a hinged door and exit or enter a room or a house when they are not supposed to do that. The locking device of the invention is also designed so as the person overseeing the child or person with mental issues leaves or enters they can secure the door. The remote capability allows only persons with the activation or deactivation remote (i.e. the overseeing person) to control the lock and unlock of the device. The main entrance of the house is the primary place for this device so those persons or children are not able to get outside but the second important place is for the bathroom door adding security to the medicine cabinet. Another useful place is a closet door that contains chemicals. Unlike a deadbolt that everyone can reach even a small child on a chair the locking devi ce of the present inventi on can be mounted high on the door and jamb and can be remote controlled. It gives security to a parent or family member that the person or child cannot get out of or into areas without permission to do so.

[0029] In a door locking assembly, according to the invention, the first and second support components are connected to a door jamb and door, respectively, and the locking members function in the manner set forth above.

[0030] As shown in Figure 9, in a method of constructing the door locking assembly, according to the invention, the door locking device, as described above, is provided, the first and second subassemblies are connected to a door jamb and door, respectively, and the locking bar is adjusted (e.g. by adjustment of the locking bar on the housing member 112, and/or adjusting the U shaped housing members 110,112 to adjust the perpendicular or angular position of the locking bar relative to the door surface, so that when the door is closed, the locking bar will fit into the slot in the second subassembly, and lie against the top plate of the second subassembly. With this adjustment, (he locking device will provide a safe and secure lock when desired. The adhesive strip 132 that secures the first subassembly to the door surface, along with the subassembly structures described herein, provides effective resistance to movement of the door in an opening direction when the pivotal latch has been moved to a position in which it locks the subassemblies against movement that would open the door.
