Abstract
Overcoming all typical limitations of fasteners, disclosed is a fully-reusable, non-deforming, precise position, drywall fastener for heavy-weight items that works by anchoring to outside of a drywall panel using a drywall hole reinforced hollow cutter bar and a precise-fit pin wall body with outside rims, while fastener anchors beneath drywall panel by a manual pivoting of fastener locking arms hinged to pin wall body. Advancement of a threaded locking bolt through a center hole of pin wall body reversibly wedges apart shoulders of locking arms to cause their lateral pivoting and then locking without over-tightening fastener parts or damaging drywall.
Claims20
A fastener for a panel having a hole and a hollow space beneath the hole for an attachment of the fastener to the panel, the fastener comprising:
- a locking bolt having a tip and a rigid shaft;
- locking arms having shoulders which can be pushed by the small tip of the locking bolt so that the shoulders undergo a rotation and free ends of the locking arms swing, and the locking arms having shoulders which can be held apart by the rigid shaft of the locking bolt so that the free ends of the locking arms remain in a fully apart position;
- pivot pins for supporting the shoulders during the rotation of the shoulders and when the shoulders are held apart by the rigid shaft of the locking bolt;
- and
- a pin wall body for holding the pivot pins, the pin wall body having a longitudinal hole for guiding the shaft of the locking bolt to the shoulders of the locking arms, the pin wall body having a rim which is situated above the panel when the pin wall body is situated in the hole of the panel.
A method for securing an item to a fastener attached to a panel over a hollow space, the method comprising the steps of:
- (a) cutting the panel to have a hole;
- (b) inserting locking arms hinged to a pin wall body into the hole of the panel,
- wherein each locking arm is connected to the pin wall body by a pivot pin,
- wherein the pin wall body has a longitudinal hole, and
- wherein the pin wall body has a rim for holding the pin wall body from falling into the hollow space below the hole of the panel;
- (c) keeping the rim of the pin wall body against an outside edge of the hole of the panel;
- (d) advancing the rigid shaft of a locking bolt in the longitudinal hole of the pin wall body;
- (e) advancing the tip of the locking bolt for contacting shoulders of the locking arms to cause rotating of the shoulders of the locking arms and pivoting of free ends of the locking arms in the hollow space beneath the panel;
- (f) advancing the tip of the locking bolt past shoulders of the locking arms to cause the free ends of the locking arms to remain adjacent to inside surfaces of the panel;
- and
- (g) securing the item to a site on the fastener which will be located on an outer side of the panel after the fastener is attached to the panel.
A method for securing a fastener to a panel over a hollow space, the fastener having a locking bolt with a threaded section and a pin wall body having a longitudinal hole with a threaded section, the method comprising the steps of:
- (a) cutting the panel to have a hole;
- (b) inserting locking arms hinged to a pin wall body into the hole of the panel,
- wherein each locking arm is connected to the pin wall body by a pivot pin,
- wherein the pin wall body has a longitudinal hole having a threaded section, and
- wherein the pin wall body has a rim for restraining the pin wall body from falling into the hollow space of the panel;
- (c) keeping the rim of the pin wall body against an outside edge of the hole;
- (d) advancing the rigid shaft of the locking bolt in the longitudinal hole of the pin wall body;
- (e) rotating the locking bolt when the threaded section of the rigid shaft of the locking bolt encounters the threaded section of the longitudinal hole of the pin wall body so as to advance the rigid shaft of the locking bolt into the threaded section of the longitudinal hole in the pin wall body;
- (f) contacting the shoulders of the locking arms with the advancing rigid shaft of the locking bolt for causing a rotation of the shoulders of the locking arms and pivoting free ends of the locking arms in the hollow space beneath the panel;
- (f) advancing the tip of the locking bolt past shoulders of the locking arms to cause the free ends of the locking arms to remain adjacent to inside surfaces of the panel;
- and
- (g) securing the item to a site on the fastener which will be located on an outer side of the panel after the fastener is attached to the panel.
