Abstract

A method and device for opening a door includes a receptacle structure. The receptacle structure is coupled to the door. The receptacle structure has a top surface and an angled guiding surface. The top surface forms an angled protrusion. The receptacle structure has a receptacle and the receptacle is formed between the top surface and the angled guiding surface. The device also includes a latching rod and a sliding assembly coupled to the latching rod. Movement of the sliding assembly causes the latching rod to contact the angled protrusion. The contact of the latching rod with the angled protrusion of the receptacle structure causes the rod to push the receptacle structure and the door to a partially open position. After contacting the angled protrusion, the latching rod navigates across the angled guiding surface of the receptacle structure, pushing the door to a further partially open position.

Claims (29)

1. A device comprising:

a receptacle structure, the receptacle structure coupled to a door, the receptacle structure having a top surface and an angled guiding surface, the top surface forming an angled protrusion, the receptacle structure having a receptacle, the receptacle formed between the top surface and the angled guiding surface;

a latching rod; and

a sliding assembly coupled to the latching rod;

wherein upward movement of the sliding assembly causes the latching rod to move upwardly in said receptacle to contact the angled protrusion;

wherein the contact of the latching rod with the angled protrusion of the receptacle structure causes the rod to push the receptacle structure and the door to a partially open position;

wherein after the latching rod contacts the angled protrusion, the latching rod moves downwardly and slides along the angled guiding surface of the receptacle structure, thereby pushing the receptacle structure and the door to a further partially open position.

2. The device of claim 1 wherein the angled protrusion forms an angle of approximately 30 degrees with a vertical axis.

3. The device of claim 1 wherein the angled guiding surface forms an angle of approximately 57 degrees with a vertical axis.

4. A receptacle structure, the receptacle structure coupled to a door, the receptacle structure comprising:

a top surface and an angled guiding surface, the top surface forming an angled protrusion, the receptacle structure having a receptacle, the receptacle formed between the top surface and the angled guiding surface; and

wherein a latching rod is positioned within the receptacle, and a sliding assembly causes the latching rod to move upwardly in the receptacle to contact the angled protrusion, and move upwardly in the receptacle to the contact of the latching rod with the angled protrusion of the receptacle structure causes the rod to push the receptacle structure and the door to a partially open position, and then the latching rod moves downwardly and slides along the angled guiding surface of the receptacle structure thereby pushing the receptacle structure and the door to a further partially open position.

5. The structure of claim 4 wherein the angled protrusion forms an angle of approximately 30 degrees with a vertical axis.

6. The structure of claim 4 wherein the angled guiding surface forms an angle of approximately 57 degrees with a vertical axis.

7. A method for opening a door comprising:

providing a receptacle structure having a top surface and an angled guiding surface, the top surface forming an angled protrusion, the receptacle structure having a receptacle, the receptacle formed between the top surface and the angled guiding surface;

positioning a latching rod within the receptacle;

moving the latching rod in an upward direction to contact the angled protrusion of, thereby causing the rod to push the receptacle structure and the door to a partially open position; and

navigating the latching rod downwardly across the angled guiding surface of the receptacle structure, thereby pushing the receptacle structure and the door to a further partially open position.

8. A storage device comprising:

a door;

a receptacle structure, the receptacle structure coupled to the door, the receptacle structure having a top surface and an angled guiding surface, the top surface forming an angled protrusion, the receptacle structure having a receptacle, the receptacle formed between the top surface and the angled guiding surface;

a latching rod; and

a sliding assembly coupled to the latching rod;

upward wherein movement of the sliding assembly causes the latching rod to move upwardly in said receptacle to contact the angled protrusion; and

wherein the contact of the latching rod with the angled protrusion of the receptacle structure causes the rod to push the receptacle structure and the door to a partially open position, and then the latching rod moves downwardly and slides along the angled guiding surface of the receptacle structure, thereby pushing the receptacle structure and the door to a further partially open position.

9. The storage device of claim 8 wherein the angled protrusion forms an angle of approximately 30 degrees with a vertical axis.

10. The storage device of claim 8 wherein the angled guiding surface forms an angle of approximately 57 degrees with a vertical axis.

11. The storage device of claim 8 wherein the sliding assembly is coupled to a foot pedal.
