The present inventive concept relates to a door latch or latching mechanism for holding a door open or closed a certain distance and a method for holding a door and a latching mechanism designed to hold a door open or closed at a prescribed distance.
For pet owners, there is a need to keep doors open so cats do not get trapped in rooms, and so dogs do not have access to the cat's litter. There is a need for a door latching device to hold a door so dogs cannot open the door by jumping on the door, while holding the door open enough for cats to pass through the door and also closed enough to keep average-sized dogs out. Moreover, the door latch mechanism should be sturdy so as to withstand a door slamming into the device, and the door latch should permit the door to open and close fully when desired without the need to remove the device.
A reliable door latch is also needed to assist with other tasks such as keeping children out of various areas, preventing children from pinching their fingers in closing doors and maintaining doors open for more efficient heating and/or cooling.
Generally, prior art devices fail to provide a sturdy door holding and/or latching mechanism that can hold a door open or closed at a prescribed distance along any point of the door frame.
Hence, there is a need for a sturdy door holding and/or latching mechanism designed to hold a door open or closed at a prescribed distance.
The present inventive concept provides a door holding and/or a door latching apparatus and method that holds a door so larger pets (greater than 50 pounds) e.g., dogs, cannot open the door by jumping on the door, while holding the door open enough for smaller pets (less than 20 pounds), e.g., cats and smaller dogs, to pass through the door and also closed enough to keep average-sized pets (around 40 pounds), e.g., dogs, out as well as keeps children out of dangerous areas, protects children from pinching their fingers in closing doors and also keeps doors held open for more efficient heating and/or cooling. The door latch is also sturdy enough to withstand a door slamming into the device, and the door latch permits the door to open and close fully when desired without the need to remove the device. The door latch device also obviates the need to modify or cut a hole in an existing door or purchase a special door to allow the ingress and egress of small pets.
In some embodiments, the presently disclosed door latch and method provide an elongated, substantially flat door latch bracket including a first end that may be fastened to the doorjamb, and wherein the first end extends toward a substantially U-shaped door latch portion for engaging with and holding the edge of a door, and wherein the U-shaped door latch portion extends toward a second end including a tab or flap member for flexing the bracket for engaging/disengaging the door with/from the U-shaped door latch portion of the device.
Further embodiments of the present inventive concept provide a door holding and/or a door latching apparatus including a first member including at least one aperture, wherein the first member is configured to affix to an area on a door frame; and a second member including at least one aperture, wherein the second member further includes an edge curved in an outward direction, wherein the first and second members include an overlapping aperture and are connected to each other by a fastener through the overlapping aperture and the connection of the first and second members provide an area to receive the door.
