This product is currently registered with an American invention patent.

Patent number: US8678453B2.

The specific details of the patent map are as follows: (There is a risk of patent infringement)

A portable door supporting device includes a first arm, a second arm and a coupling member. The first arm is pivoted with the second arm, and the portable door support device can be hung on the door hinge to support the door in an open position.

The invention provides a portable door supporting device for hanging on a hinge of a door to support the door in an open position.

Claim:

A portable door brace device comprises a first arm including a first wing and a first hub, wherein the first wing includes a first plane and the first hub defines a first hole; The second arm includes a second wing and a second hub, the second wing includes a second plane, and the second hub defines a second hole; And the coupling member includes a hinge pin and a hook, wherein the hinge pin defines a hinge axis and extends into each of the first hole and the second hole; Wherein the first arm is pivotable relative to the second arm about the hinge axis between an open position and a closed position; When the first arm is in the open position, the hook is configured to be hung on the door hinge, the first plane of the first wing and the second plane of the second wing are adjacent to each other, and the first wing and the second wing cooperate to form a rigid stop for supporting the door; And when the first arm is in the closed position, the first wing and the second wing face each other and clamp at least a part of the hook together.

A method of supporting a door in an open position relative to a door frame, the door being pivotally connected to the door frame by at least one door hinge, the method comprising: pivoting a first arm of a portable door supporting device from a closed position to an open position about a hinge axis relative to a second arm of the portable door supporting device, wherein the first arm comprises a first wing and a first hub, the first wing comprises a first plane, the first hub defines a first hole, and the second arm comprises a second wing and a second hub, The second wing includes a second plane, the second hub defines a second hole, the hinge shaft is defined by a hinge pin of a coupling member of the portable door support device and extends into each of the first hole and the second hole, and the coupling member further includes a hook extending into a space defined between the first arm and the second arm, when the first arm is in a closed position; And hanging the hook on the door hinge when the first arm is in the open position, so that the first arm abuts against the door and the second arm abuts against the door frame, and the first plane of the first wing and the second plane of the second wing are adjacent to each other and cooperate with the first wing and the second wing to form a rigid blocking member supporting the open door.

Patent summary:

1. A portable door brace device consists of a first arm, a second arm and a coupling member;

2. The two arms are composed of wings (planes) and hubs, and the hubs define holes; The hinge of that connecte member consist of a chain pin and a hook; The first arm can rotate around the hinge axis relative to the second arm;

3. When the first arm is in the open position, the hook is hung on the door hinge, and the two planes are adjacent to each other to form a door stop; In the closed position, the two planes face each other, and a part of the hook is sandwiched.
