A system for removing, storing and precisely re-installing removable automobile doors. This system includes a mobile base for positioning near the vehicle and moving stored doors to their storage location. The base of this system provides mounting positions for 2 or more lifting/storing/re-installation devices, accommodating full service (removal, storage and re-installation) of up to 4 doors at once. The lifting/storage/re-installation devices contain full 3 axis precise adjustment and rigid coupling to each of the vehicle's doors. Without this precision, the weight and non-balance of removing/re-installing the doors can cause the door to tilt into or away from the vehicle, possibly crushing a human body part (finger, hand) and/or damaging the vehicle or door. By rigidly coupling the door to the precisely adjusted device, precise vertical lifting and lowering may be used to remove and re-install the doors, including accommodating surface variations encountered from removal to re-installation time.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

A safety gate has a gate body and two first locking units. The gate body has two first connecting elements. The two first locking units are respectively mounted on two opposite sides of a door frame. Each first locking unit has a second connecting element and a blocking element. Each of the first connecting elements is rotatably connected with a respective one of the second connecting elements. Each blocking element has a blocking position for blocking a corresponding first connecting element to prevent it from being disengaged from the second connecting element and a pressed position for detaching the corresponding first connecting element from the second connecting element of the first locking unit.

A multi-panel kit defining one or more recesses for a structural joint. The kit including first and second panels for respectively defining first and second faces of the one or more recesses in use. One or more intermediate panels, each defining an intermediate face of at least one, of the one or more recesses in use, and one or more pairs of slots, each comprising a first slot through the first panel and a second slot through the second panel. The one or more recesses are intermediate the first and second panels, and the intermediate faces of each recess extending between the first and second faces of that recess. Each pair of slots is for receiving one of the one or more intermediate panels in use, and each of the one or more intermediate panels includes a first notch and a second notch for receiving an edge of the first slot and an edge of the second slot of a pair of slots respectively in use.

A system is disclosed for converting an overhead door into a gate or serving window, the system having at least two rows of panels spanning the width of the door, one panel located above and adjacent to the other panel, a pair of rails opposite one another and adjacent to the panels, the panels traveling within the rails to move from a closed position to an open position, and at least one hinge connecting the lower row of panels to the upper row of panels, the hinge having an upper half attached to the upper row of panels and a lower half attached to the lower row of panels, the upper and lower halves of the hinge connected by a removable central pin, wherein the upper row of panels moves from the closed position to the open position when the central pin is removed from the hinge.

A barrier that includes four structurally different corner connections for fixing a gate frame of the barrier to and between opposing vertical surfaces. A first connection includes a headed straight pin engaging a pivot hook and socket, a second connection includes a headed straight pin engaging a socket, a third connection includes headless bent pin engaging a socket and a limiter, and a fourth connection includes a headless bent pin engaging a socket.

A shower door and hinge assembly comprising a glass shower door, a sloping sill, a sill angle adapter, upper and lower horizontal door frame rails, and upper and lower shower door hinges where the lower hinge is a gravity style hinge featuring a self-closing action, is presented. The hinges of the present invention shower door and hinge assembly attach only to horizontal edge surfaces of the glass door. The hinges do not attach to any vertical surface of the door.

A multi-position door hinge is coupled to a vehicle and includes a first hinge having a pin support, a pin, and a key. The multi-position door hinge additionally includes a second hinge having a receiving cam, a key way, and a cam groove. The multi-position door hinge is formed by coupling the first hinge to the second hinge by positioning the pin in the receiving cam with the key positioned in the key way.

A shower door and hinge assembly comprising a glass shower door, a sloping sill, a sill angle adapter, upper and lower horizontal door frame rails, and upper and lower shower door hinges where the lower hinge is a gravity style hinge featuring a self-closing action, is presented. The hinges of the present invention shower door and hinge assembly attach only to horizontal edge surfaces of the glass door. The hinges do not attach to any vertical surface of the door.

A gate is provided and includes a gate body, a hinge assembly attached to a first side of the gate body, and a support bracket. The hinge assembly includes a pin assembly and an actuating assembly capable of moving a pin of the pin assembly between a retracted position and an extended position. The support bracket engages the pin in the extended position and is disengaged from the pin in the retracted position. The gate body has an axis of rotation extending through the pin when the pin engages the support bracket and is freely movable with respect to the support bracket when the pin is disengaged from the support bracket.
