Child safety doors described herein can keep babies, toddlers, and children of other ages from accessing areas of a house or other building. In one aspect, a child safety door includes a door with a first side and a second side opposite the first side. The door has a height of at least sixty inches and a width of at least twenty-four inches. The door has an opening that extends through the door from the first side to the second side. The opening is located at a top half of the door when the door. The opening has spindles that each extend from a bottom of the opening to a top of the opening. The door has a locking mechanism that, when locked, prevents a person from opening the door from either side of the door without placing the locking mechanism in an unlocked position.

A safety gate for preventing pets and small children from passing through an opening, the safety gate comprising: a collapsible frame for selective disposition in the opening, the collapsible frame comprising: a resizable base having a first end and a second end, the resizable base being configured so that the distance between the first end and the second end is adjustable; and first and second arms adjustably secured to the first and second ends of the resizable base, respectively, so as to be re-configurable between (i) a collapsed configuration wherein the first and second arms extend substantially parallel to one another and substantially parallel to the resizable base, and (ii) an expanded configuration wherein the first and second arms extend upright from the resizable base so that the collapsible frame comprises a substantially U-shaped configuration defining a space between the resizable base and the first and second arms; and a flexible barrier for adjustable mounting to the collapsible frame so as to prevent a pet or small child from passing through the space between the resizable base and the first and second arms.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A gate unit includes a gate mount and a gate coupled to the gate mount for swinging movement between opened and closed positions. A latch assembly is coupled to the gate to lock the gate in the closed position. The gate unit can be mounted in a doorway.

The invention is directed to a protective barrier for an open window. The barrier is comprised of a plurality of thin, flexible filaments drawn taut between two posts, which are secured to the window frame. The filaments may be comprised of monofilament fishing line or some other strong, flexible material that is corrosion resistant. The purpose of the barrier is to protect objects placed on the window sill from being knocked off by a gust of wind, or by a passing person or animal. In a second embodiment, additional filaments are provided in a diagonal crisscross pattern to protect smaller objects.

A child window safety system based on building a reliable safety net to prevent children from leaning and falling out through open windows is installed and uninstalled without any damage to a window. The child window safety system is mass produced to fit windows at all sizes for an installer to form a window gap vertically and horizontally with thin steel cords and fastening the thin cords to each other at an installation site.

A retraction barrier can abut objects in the environment for safeguarding. The retraction barrier has multiple longitudinal poles separate from each other and multiple lateral poles separate from each other. The longitudinal poles are connected with the longitudinal poles so that the retraction barrier forms a grid, making the retraction barrier capable of isolating something. The longitudinal poles and lateral poles are each a retractable pole. Lengths of the longitudinal poles and the lateral poles can be changed so that each end of the longitudinal poles and the lateral poles can abut an object in the environment, so the retraction barrier can be secured with objects of any dimensions and shapes. For storage of the retraction barrier, the lateral poles and the longitudinal poles are retracted, so that the volume of the retraction barrier is lessened for ease in carriage.

A security system and method for preventing unwanted passage through windows and doors of a building includes custom sizing and welding of hardened steel structures that mount into the door jamb or window frame, on the inside of the door or window with the use of threaded fasteners. The custom assembled structure consists of an outer frame and horizontal and vertical pickets that may be formed of flat stock, hollow square or rectangular steel tubing or solid square hardened steel bars. The system and method involves specifically spacing the vertical and horizontal pickets so as to lineup with an ornamental structure on the window or door (e.g., grids) without obstructing the view of the door or window so that the steel bars of the security structure is essentially invisible.
