Description
- The present application claims the benefit of U.S. Provisional Applications Ser. Nos. 61/079,450 and 61/089,173, filed on Jul. 10, 2008 and Aug. 15, 2008, respectively. The entire contents of the provisional applications are incorporated herein by reference.
- The present disclosure relates to a wall fastener. More particularly, the present disclosure relates to a nut for a wall fastener for use in applications where it is difficult to gain access behind drywall to hold a nut while a bolt attaches to the nut.
- Fasteners made from plastic or metal which attach themselves to a wall by expanding into a pre-drilled hole are known in the art. Drywall (e.g., Sheetrock®) is generally made from gypsum or plaster and does not have any appreciable anchoring strength to accommodate surface fasteners for the support of mirrors, paintings, kitchen and bathroom fixtures, curtain rods, etc.
- Other types of fasteners such as plaster screws generally tend to pull free from drywall when slight stresses are applied because drywall composition provides little anchoring support for these types of fasteners.
- Other fasteners are known as toggle-bolt type where the cross-member collapses to insert into the wall and then once through the hole, opens and can not be pulled back out. Due to the collapsible mechanisms they are complex and require a large hole through the wall. They are therefore less desirable, especially when multiple holes are required in close proximity to each other.
- Many fasteners require considerable space in the back of the wall board which is not always available. Particularly, in buildings constructed with concrete blocks or having a poured concrete wall. In this instance, the drywall is typically attached to the concrete wall by shallow furring strips.
- Accordingly, there remains a need for a wall fastener that can overcome the above-identified limitations. It will be clear to those of ordinary skill in the art, that the disclosed wall fastener can be used with other types of walls, in addition to drywall.
- A wall fastener system is described herein, and in particular, a nut for a wall fastener is described. The nut for the wall fastener comprises a major planar structure having a hole for receiving a screw or bolt, the major planar structure having a first end with one or more staggered knife edges and a second end; and a string forming a loop, wherein the string loop is detachably connected to the major planar structure in an area adjacent to the hole for receiving the screw.

FIG. 1 is a schematic representation of a nut for the wall fastener according to a preferred embodiment of the present invention. -
FIG. 2 is a schematic representation of a nut for the wall fastener according to a second preferred embodiment of the present invention. -
FIG. 3 is a schematic representation of a nut for the wall fastener according to a third preferred embodiment of the present invention. - The term “wall” and “drywall” are used interchangeably in the present disclosure and refer to the common construction product made from gypsum or plaster to form walls for finishing construction of interior walls and ceilings.
- The wall fastener described herein is preferably made from a metal or a metal alloy. In an exemplary embodiment, the wall fastener is made of a metal or metal alloy such as steel, tempered steel, stainless steel, titanium, brass, bronze, monel, and/or silicon bronze. However, one of ordinary skill in the art may find that other materials are also suitable.
- As shown in
FIG. 1 , thenut 10 for the wall fastener has a major planar structure referred to as the plate-nut 20 in this disclosure. The plate-nut 20 has afirst end 40 for guiding and inserting into the wall and asecond end 50 with anotch 90 where a screwdriver blade can be inserted sideways. Thenotch 90 aids in positioning and insertion of the wall fastener onto and inside the wall. However, some embodiments may not include thenotch 90. - The
first end 40 has two staggeredknife blades FIG. 1 ). This configuration of the two staggered knife blades at opposite sides permits both blades to cut differently from each other as to cutting depth, pressure distribution, while hammering into the wall. This may help to avoid damage to the backside of the wall, especially at the point of exit of the wall fastener. - The presently described
nut 10 for the wall fastener can be installed by drilling ahole 15 in awall 25. In an exemplary embodiment, the drilled hole can be about 5.0 mm or about 3/16 inch in diameter. Then, thefirst end 40 of the plate-nut 20 can be inserted into the drilled hole. Insertion of the plate-nut 20 can be aided by hammering until the plate-nut 20 is flush with the wall. A protruding portion of the plate-nut 20 can be pushed through the wall with a nail or a small screw driver while holding on to a loop ofstring 80 which is connected to the plate-nut 20 viaholes 100. A longitudinal axis of the plate-nut is identified byreference numeral 45. - The plate-
nut 20 includes ahole 30 in a central portion thereof for receiving a screw or bolt. Thehole 30 is surrounded by aflange 75 that extends from one surface of the otherwise flat plane of the plate-nut 20. - As the plate-
nut 20 passes through the wall, the plate-nut 20 creates two slots on opposite sides of thehole 15. After the plate-nut 20 has completely passed through the wall, thestring loop 80 is pulled to position the plate-nut 20, as desired, parallel to and on the backside of thewall 25. Pulling on thestring loop 80 will cause thestring loop 80 to move into the newly created slots and will position the plate-nut 20 such that thehole 30 in the plate-nut is aligned with the drilledhole 15 in thewall 25. Tension can also be applied to thestring loop 80 while inserting the screw to aid in engaging the screw with thehole 30 in the plate-nut 20. Because of the arrangement of theholes 100, thestring loop 80 will prevent theplate nut 20 from rotating while the screw is being applied. After the screw is inserted into thehole 30 thestring loop 80 can be removed by using a pair of scissors or a knife. - The string of the
string loop 80 can be made of any suitable material, such as nylon, and can be optionally cut with a common cutting instrument such as a pair of scissors or a knife. For example, the string loop can be made from plastic, metal and/or a natural fiber. - In an exemplary embodiment, the wall fastener is about 11 mm wide and about 25 mm long. The
hole 30 is about 3.2 mm in diameter. Thenotch 90 is about 4.75 mm deep, and the portion of the leading edge between theedges - Some of the advantages of the wall fastener described herein and shown in
FIG. 1 include: (i) small size and good load bearing capacity, (ii) compared to its load bearing capacity the wall fastener has minimal intrusion into the dry-wall thus minimizing the hole in the wall at the point of entry, (iii) minimal to no damage to the backside of the wall compared to expansion type wall fasteners, (iv) no special tools are required to install, (v) easy to install, (vi) easy to manufacture due to its simple construction, (vii) inexpensive to produce, (viii) several of these fasteners can be installed in close proximity of each other without significantly impacting the strength and integrity of the wall because the presently described wall fastener causes minimal intrusion and damage compared with traditional expansion type wall fasteners, and (ix) desirable as a replacement fastener where other expansion type fasteners have failed. - In the above disclosed
embodiment 10, the knife edges are staggered and are arranged at an angle of about 26 degrees from thelongitudinal axis 45 of thenut 10. However, in analternative embodiment 100, illustrated inFIG. 2 , theknife edges longitudinal axis 145 of the plate-nut 120. In thealternative embodiment 100, because theknife edges nut 120 is symmetrical. The remaining features of thesecond embodiment 100 are substantially the same as thefirst embodiment 10. Corresponding reference numerals have been increased by 100 in the second embodiment. - A
third embodiment 200 is shown inFIG. 3 . The nut for thewall fastener 200 has a major planar structure referred to as the plate-nut 220 in this disclosure. The plate-nut 220 has afirst end 240 for guiding and inserting into a wall 225 and asecond end 250 with anotch 290 where a screwdriver blade can be inserted sideways. Thenotch 290 aids in positioning and insertion of the wall fastener onto and inside the wall 225. However, some embodiments may not include thenotch 290. - The
first end 240 has knife edges 260, 270 that are not staggered. The knife edges 260, 270 are arranged at an angle of about 19 degrees from thelongitudinal axis 245 of the plate-nut 220. - The plate-
nut 220 includes ahole 230 in a central portion thereof for receiving a screw or bolt. Thehole 230 is surrounded by aflange 275 that extends from one surface of the otherwise flat plane of the plate-nut 220. - The presently described nut for the
wall fastener 200 can be installed by drilling ahole 215 in the wall 225. In an exemplary embodiment, the drilledhole 215 can be about 5.0 mm or about 3/16 inch in diameter. Then, thefirst end 240 of the plate-nut 220 can be inserted into the drilled hole. Insertion of the plate-nut 220 can be aided by hammering until the plate-nut 220 is flush with the wall. A protruding portion of the plate-nut 220 can be pushed through the wall with a nail or a small screw driver while holding on to astring 280 which is connected to the plate-nut 220 via ahole 300 provided in theflange 275 of thehole 230. Thestring 280 can be a simple straight length of string, or it can have a loop formed at the end of it to facilitate holding. The diameter of the hole may be about 0.8 mm. - The string can be threaded through the hole and secured to the plate-nut by having a stop at the end of the string that will not pass through the hole. The stop can be simply a knot or a melted portion of the string. Alternatively, a notch in the flange can be used instead of the
hole 300. - As the plate-
nut 220 passes through the wall, the plate-nut 220 creates two slots on opposite sides of the hole. After the plate-nut 220 is completely through the wall, thestring loop 280 is pulled to position the plate-nut 220, as desired, parallel to and on the backside of the wall. Pulling on thestring loop 280 in an upward direction will cause thestring loop 280 to move into the newly created slot at the top, and positions the plate-nut 220 such that thehole 230 in the plate-nut is aligned with the drilled hole in the wall. Gravity will ensure that the plate-nut 220 swings down so that thehole 230 is in alignment with the hole drilled in the wall. Tension can also be applied to astring loop 280 while inserting the screw to aid in engaging the screw with thehole 230 in the plate-nut 220. After the screw is inserted into thehole 230 thestring loop 280 can be removed by using a pair of scissors or a knife. - The string of the
string loop 280 can be made of any suitable material, such as nylon, and can be optionally cut with a common cutting instrument such as a pair of scissors or a knife. For example, the string loop can be made from plastic, metal and/or a natural fiber. Thestring 280 may have sufficient stiffness that when the nut-plate 220 is first pushed through the wall, the nut-plate 220 hangs by thestring 280 such that the bottom of the nut-plate 220 is touching the back of the wall, but thetop end 240 of the nut-plate remains spaced from the wall. As thestring 280 is pulled, then the nut-plate lies flush against the wall. - In all of the exemplary embodiments, the wall fastener is preferably about 11 mm wide and about 25 mm long. The
hole notch edges - Additional embodiments are also contemplated. For example, and without limitation, the third embodiment can also be made with staggered knife edges, such as are used in the first embodiment.
- Some of the advantages of the wall fastener described herein include: (i) small size and good load bearing capacity, (ii) compared to its load bearing capacity the wall fastener has minimal intrusion into the dry-wall thus minimizing the hole in the wall at the point of entry, (iii) minimal to no damage to the backside of the wall compared to expansion type wall fasteners, (iv) no special tools are required to install, (v) easy to install, (vi) easy to manufacture due to its simple construction, (vii) inexpensive to produce, (viii) several of these fasteners can be installed in close proximity of each other without significantly impacting the strength and integrity of the wall because the presently described wall fastener causes minimal intrusion and damage compared with traditional expansion type wall fasteners, and (ix) desirable as a replacement fastener where other expansion type fasteners have failed.
- Although only preferred embodiments are specifically illustrated and described herein, it will be appreciated that many modifications and variations of the present invention are possible in light of the above teachings and within the purview of the appended claims without departing from the spirit and intended scope of the invention.
