Abstract

A quick release fastener mechanism for easy installation and removal of conventional hurricane storm shutters over and from a window or door of a structure. The device comprises a removable stud for engaging and securing the hurricane shutters and a spring-actuated panel fastener that includes a leaf spring and hinged locking element to engage and hold the removable stud in position. The quick release fastener is installed and removed from outside the building by actuating or depressing a lever end of the hinged locking element to lock or to unlock and release the removable stud from within the spring-actuated panel fastener.

Claims

1. A quick release fastener device for quickly installing and securing and for releasing and removing a temporarily-installed hurricane shutter panel from a window or door over which said shutter is installed, comprising:

a stud having at least one end that is connectable to a building structure to hold a hurricane storm shutter in place over a window, door, or other opening of the structure; and

a spring-actuated panel fastener removably connected to an end of said stud oriented away from the structure for holding said hurricane shutter in place, said fastener including a panel fastener body, a hinged locking element, and a spring for manually installing and removing said fastener on and from said stud;

wherein the spring-actuated panel fastener comprises;

the spring, which comprises a leaf spring;

the panel fastener body that includes;

a planar first face;

a central recess passing through said planar first face and extending longitudinally downward into said panel fastener body, said central recess being defined by one or more inner walls and a planar bottom surface of the panel fastener body;

a planar second face;

an outer wall; and

a central aperture for receiving the removable stud that extends entirely through the said panel fastener body with openings on both the first face and the second face of the panel fastener body;

a slot-shaped aperture extending longitudinally through the planar second face and into the central recess of said panel fastener body for receiving the leaf spring; and

a central protrusion having a groove that is coaxial and colinear with the central aperture, said central protrusion being connected to and extending upward from the planar bottom surface defining the central recess; and

a hinged locking element having a groove that is opposite and corresponding in position and identical in size to the groove of said central protrusion, wherein said locking element is connected to the panel fastener body and securely engages the removable stud within said groove of the locking element when said fastener is not actuated.

2. The quick release fastener device of claim 1, wherein said stud is a removable stud comprising a dowel having:

an outer wall;

a first end for engaging the panel fastener body and hinged locking element;

a second end for connecting to the building structure and for inserting through a stud-receiving installation aperture of the shutter; and

a series of annular grooves adjacent to said second end for engaging the fastener.

3. The quick release fastener device of claim 1, wherein said panel fastener body further comprises:

a base portion that includes said second face and said outer wall;

a top portion that has a greater diameter than said base and that includes said first face and a partial annular bottom face;

said panel fastener body also including a side aperture opening into the central recess for receiving insertion and installation of the hinged locking element; and

said panel fastener body further including means for securely engaging the hinged locking element to retain said locking element within the central recess and to maintain alignment between the groove of the locking element and the groove of the central protrusion, thereby extending the central aperture with which said grooves are colinear and coaxial.

4. The quick release fastener device of claim 3, wherein the means for securely engaging the hinged locking element comprises two circular recesses located on opposing sides of the inner wall defining the central recess;

wherein said recesses each receive one end of one or more fulcrum components of the hinged locking element that are rotatable within said recesses to allow pivoting of a lever and of a vertical engaging section that includes the groove of said locking element.

5. The quick release fastener device of claim 3, wherein said hinged locking element further comprises:

an actuating lever for manual manipulation to open the panel fastener body and release the removable stud;

a series of ridges located within the groove of said locking element and sized and spaced to engage the series of ridges of the removable stud to lock and retain said stud in position; and

means for engaging the leaf spring, wherein said leaf spring provides the tension to maintain said hinged locking element in the closed, locked position with respect to the central protrusion thereby securely engaging and holding the removable stud within the central aperture of the panel fastener body and between the grooves of the central protrusion and the locking element.

6. The quick release fastener device of claim 1, wherein the leaf spring includes:

a metallic, preferably stainless steel, tension leaf spring that is inserted into the slot-shaped aperture passing through the planar second face of the panel fastener body and extends into the central recess of said panel fastener body; and

an aperture for engaging said leaf spring with the hinged locking element;

wherein said leaf spring also includes a longer angled end for providing spring tension to engage and hold the removable stud; and

wherein said leaf spring is depressed by actuating an actuating lever of the hinged locking element to decrease the tension exerted by said spring on the hinged locking element that forces said locking element against the groove of the central aperture.

7. The quick release fastener device of claim 6, wherein the leaf spring engages said removable stud in a locking position configuration when not depressed due to the tension of said spring against the hinged locking element in the direction of the groove of the central protrusion of said panel fastener body and wherein said leaf spring releases said removable stud when the actuating lever of the hinged locking element is depressed due to a relaxation of tension and contact by the ridges of the groove of said locking element with the surface of the grooves of the removable stud.
