Abstract

A child safety door lock system includes a door latch device having a main body with a first cavity, a second cavity and a recessed middle section. The middle section is dimensioned for positioning the main body onto the edge of a door. A latch assembly is positioned along the main body and includes two posts that are positioned within the first and second cavities, and a hook that extends outward from the second cavity. A door catch having an opening along the front wall is secured onto the frame of the door. The door catch and door latch are horizontally aligned such that closing the door will position the hook within the opening of the catch to lock the door. The hook is removed from the catch and the door is unlocked by lifting either of the posts.

Claims (11)

  1. 1 . A child safety system, comprising: a door latch body that includes a first end, a second end, a middle section, a top end, and a bottom end; a latch assembly that is positioned within the door latch body, said latch assembly including a hook that extends outward from the second end; a catch body having a front wall, and an inside facing sidewall; and an opening that is disposed in the front wall, said opening having an upper lip and a lower lip, wherein the door latch body is configured to be secured onto an edge of a door, wherein the catch body is configured to be secured onto a frame of the door, and wherein the hook is configured to selectively engage the catch body to secure the door in a locked position when the door is closed against the door jamb.
  2. 2 . The system of claim 1 , wherein the middle section of the door latch body includes a recessed area having a dimension that is complementary to a cross sectional dimension of the door edge.
  3. 3 . The system of claim 1 , wherein the hook is slidingly connected to the door latch body.
  4. 4 . The system of claim 3 , wherein the hook is configured to slidingly engage the upper lip or the lower lip of the catch body to automatically secure the door in the locked position.
  5. 5 . The system of claim 1 , further comprising: a first cavity that is positioned along the first end of the door latch body.
  6. 6 . The system of claim 5 , further comprising: a second cavity that is positioned along the second end of the door latch body.
  7. 7 . The system of claim 6 , further comprising: a first post that is positioned within the first cavity.
  8. 8 . The system of claim 7 , further comprising: a second post that is positioned within the second cavity.
  9. 9 . The system of claim 8 , further comprising: a latch arm that is connected to each of the first post and the second post.
  10. 10 . The system of claim 9 , wherein the hook is connected to the second post.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. application Ser. No. 63/716,399 filed on Nov. 5, 2024, the contents of which are incorporated herein by reference. Technical Field The following disclosure contemplates various embodiments of a child safety door locking system that automatically engages when a door is closed to securely lock the door to prevent the same from being opened by a child. BACKGROUND The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. When young children are present in a home or office location, it can sometimes be necessary to restrict rooms in which they are able to enter/exit. For this reason, there are many known types of child safety mechanisms which can be secured onto a door. The goal of these products is to prevent the child from opening the door while allowing access by a parent or caregiver. Although useful, these devices must be mounted onto the door itself by screws or other such hardware which damages the door and leaves unsightly holes when it is ultimately removed. Additionally, these devices are typically constructed as passive mechanisms that only work when manually locked by the adult. As such, the adult must remember to engage the child safety device each time they enter or exit the room. Unfortunately, it is not uncommon for the adult to forget to engage the safety lock, thus allowing the child to wander from the room, sometimes with horrible consequences. The present invention, directed to a child safety door lock system differs from the conventional art in a number of aspects. The manner by which will become more apparent in the description which follows, particularly when read in conjunction with the accompanying drawings. SUMMARY OF THE INVENTION The present invention is directed to a child safety door lock system. One embodiment of the present invention can include a door latch device that is connected to a door, and a door catch device that is connected to the door frame. The door latch device can include a main body having a first cavity, a second cavity and a recessed middle section. The middle section can include dimensions suitable for positioning the main body onto the edge of an inswing or outswing door. A latch assembly can be positioned along the main body and can include a pair of posts that are positioned within the first and second cavities, and a hook having a curved surface that extends outward from the second cavity. The door catch can include a generally rectangular-shaped member having an elongated sidewall for securement onto the jamb of a door frame, and an opening along the front wall. The door catch and door latch device can be horizontally aligned such that closing the door will cause the hook to be positioned within the opening of the door catch, thus securing the door in the locked position. The system can be unlocked by moving either of the posts to lift the hook and remove the same from the catch. This summary is provided merely to introduce certain concepts and not to identify key or essential features of the claimed subject matter.
