Abstract
Description
- 1. Field of the Invention
- The present invention relates to wall fixtures and, more particularly, to a wall anchor for use in different materials including friable materials, e.g. gypsum.
- 2. Description of the Prior Art
- There are various wall anchors available on the market, including plastic inserts which are hammered in a hole previously defined in a wall with a fastener, such as a screw, being then engaged in the plastic insert, causing it to expand such that the assembly of the insert and the fastener is set in the wall.
- Toggle bolts also exist, wherein rotation of a bolt causes wings to deploy behind the wall and to ultimately abut the inside of the wall thereby firmly anchoring the bolt to the wall.
- Both these types of anchors necessitate that a hole be previously drilled in the wall. On the other hand, there exists wall anchors defining a pointed cutting end and large threads, which are adapted to, in a single step, be rotatively driven in the wall thereby drilling their own hole in the wall with the large threads of the anchor compacting the gypsum and becoming firmly set therein. These types of anchors must be installed by way of a screwdriver and typically by a power driven screwdriver bit.
- For instance, a screw tipped anchor with a toggle is disclosed in U.S. Pat. No. 6,250,865-B1 which issued on Jun. 26, 2001 in the name of McSherry.
- Also of interest is U.S. Pat. No. 5,944,295 that issued on Aug. 31, 1999 in the name of McSherry, which discloses a pair of separate components, namely a wall anchor and a fixture. The fixture, e.g. a hook, is secured to a friable wall using the wall anchor that is inserted through a hole defined in the fixture and then rotatably driven in the wall typically via a power driven screwdriver bit.
- It is therefore an aim of the present invention to provide a novel wall anchor of simple installation and that can be installed in friable walls as well as in solid structural members.
- Therefore, in accordance with the present invention, there is provided a convertible anchor for friable walls, comprising a fixture for holding an article to a substantially vertical support and anchoring means extending from said fixture, said anchoring means being adapted when rotated to engagingly extend into a friable wall for securing said fixture to the wall, said fixture being selectively separable from said anchoring means for allowing said fixture to be used alone with an appropriate fastener that firmly mounts said fixture to a rigid structure.
- A frangible connection is provided between said fixture and said anchoring means, said frangible connection being sufficiently solid to allow the assembly of said fixture and said anchoring means to be rotatably installed to the friable wall while being adapted to be selectively broken for separating said fixture from said anchoring means.
- Said anchoring means can comprise a threaded anchor member configured and sized for firmly being engageable in the friable wall. Typically, a space is defined between said fixture and a proximal end of said threaded anchor member. Generally, said space is bridged by said frangible connection.
- Alternatively, said anchoring means comprises a toggle support extending from said fixture and being frangibly connected thereto, a toggle bolt pivotally mounted to said toggle support between a first and second position, and a fastener, wherein in said first position said toggle bolt is substantially parallel to said toggle support to allow said anchoring means to be engaged in the friable wall, whereas in said second position said toggle bolt is substantially transversal to said toggle support, said fastener being adapted when introduced along said toggle support to cause said toggle bolt to displace from said first to said second position and to then threadably engage said toggle bolt for drawing said toggle bolt towards said fixture and against a non visible side of the friable wall thereby securing said anchor to the friable wall.
- Said fastener can be used to mount said fixture to the rigid structure once said anchoring means including said toggle support and said toggle bolt have been detached from said fixture by rupturing said frangible connection.
- For instance, said frangible connection comprises a pair of parallel elements extending parallelly to said toggle support and connecting a proximal end of said toggle support to said fixture.
- Said parallel elements, if extending outwardly of said proximal end of said toggle support, may be adapted when translationally inserted in the friable wall to set said anchor in a desired position in the friable wall and oppose a rotation of said anchor in the wall friable wall.
- A space may be conveniently defined between said fixture and said proximal end of said toggle support, said space being bridged by said parallel elements.
- Typically, said fixture defines an opening adapted to be engaged by a screwdriver bit for mounting said anchor to the friable wall.
- Generally, said toggle bolt is provided with a leading screw tip for engaging, when said toggle bolt is in said first position thereof, the friable wall as said anchor being installed thereto.
- Also in accordance with the present invention, there is provided a method for installing a wall anchor into one or the other of a friable wall and a rigid structure, comprising the steps of:
- (a) providing a convertible wall anchor having a fixture adapted to hold an article to a substantially vertical support and anchoring means extending from said fixture and adapted for mounting to a friable wall for securing said fixture to the wall, said fixture being selectively separable from said anchoring means;
- (b) determining a nature of the vertical support and proceeding with step (c1) in the event that the vertical support is a friable wall or with step (c2) in the event that the vertical support is a rigid structure unsuited to be penetrated by said anchoring means; and
- (c1) mounting said convertible anchor to the friable wall with said fixture being on a visible side of the friable wall, or (c2) separating said fixture from said anchoring means and installing said fixture to the rigid structure via a fastener suitable for insertion into the rigid structure.
- Typically, at least when the rigid structure is wood-based, said fastener in step (c2) is a screw.
- Having thus generally described the nature of the invention, reference will now be made to the accompanying drawings, showing by way of illustration a preferred embodiment thereof, and in which:
-

FIG. 10 is a side view showing the toggle hook ofFIG. 1 being separated in two so as to detach the toggle member thereof from a hook fixture of the toggle hook; and -
FIG. 11 is a cross-sectional side view showing the hook fixture, devoid of the toggle member of the toggle hook following its removal as perFIG. 10 , mounted with a screw to a wooden structural member. -
FIGS. 1 to 8 illustrate a wall mounted toggle hook H in accordance with the present invention, with a fastener F, such as a screw, being shown inFIGS. 1 and 5 to 8. The toggle hook H comprises a screw tippedanchor 10 that is, for instance similar to that of the anchor assembly of aforementioned U.S. Pat. No. 6,250,865-B1 (which is herein incorporated by reference), but without the proximal flange thereof (that is engaged by the screwdriver bit to rotatably install the anchor assembly in a friable wall). In the present hook H, such a flange is replaced by ahook fixture 12 that is similar to thehook fixture 20 of aforementioned U.S. Pat. No. 5,944,295. - The
anchor 10 and thehook fixture 12 are herein frangibly connected at 14 such that theanchor 10 can be snapped off (as seen inFIG. 10 ), e.g. via pliers, from thehook fixture 12 when it is desired to install thehook fixture 12 to a hard member, such as a wooden structural component, e.g. a 2″×4″. Indeed, the hook H is generally intended for hollow walls W made of friable material (e.g. gypsum walls), wherein acruciform opening 16 defined in thehook fixture 12 is engaged by a manually driven or power driven screwdriver bit B (seeFIG. 9A ) such that rotation of the bit B causes the whole hook H to rotate alongarrow 100 inFIG. 9A , with theanchor 10 thereof boring an opening O in the wall W. - More particularly, the
anchor 10 includes apivotable toggle bolt 18 provided with ascrew tip 20 that is partly opened to define acavity 21. Thetoggle bolt 18 is pivotally mounted to a pair of fixedparallel posts 22 of theanchor 10. A pair of parallel blades 24 (also called anti-rotation tabs) are provided between thehook fixture 12 and theposts 22 so as to frangibly connect thehook fixture 12 to theanchor 10. The blades are sufficiently strongly connected to thehook fixture 12 and to theanchor 10 to allow the toggle hook - H to be engaged in and mounted to the friable wall W, as shown in
FIGS. 9A to 9E , but will, when sufficient force is applied, yield and so allow thehook fixture 12 to be removed from theanchor 10 for use with the fastener F to mount thehook fixture 12 only (i.e. without the anchor 10) to a hard structural component. - Returning to the use of toggle hook H in a friable wall W, when the
anchor 10 is rotatably driven into the wall W, thetoggle bolt 18 is parallel to theposts 22 as seen inFIGS. 5 and 9A , whereby the screw tip drills the opening O in the wall W. In this first position of thetoggle bolt 18, thetoggle bolt 18 is retained in alignment parallel between the twoposts 22 by the engagement of a pair of ridges 28 (FIGS. 4 and 8 ) provided along inside surfaces of theposts 22 with a pair of channels 30 (FIGS. 1 and 8 ) defined on outside surfaces of thetoggle bolt 18. - Once the opening O has been drilled but before the
blades 24 engage the wall W, rotation of the hook H by the screwdriver bit B is interrupted, i.e. at the position of the toggle hook H illustrated inFIG. 9B . - The toggle hook H is positioned, either using the bit B or by manually rotating the
hook fixture 12, such that thehook fixture 12 is in its vertical orientation shown inFIGS. 1 to 3 and 9B. The toggle hook H is thereafter pushed translationally straight towards the wall W, alongarrow 102 as seen inFIG. 9B , such that theblades 24 cut into the friable wall W thereby setting the hook H and itshook fixture 12 in the desired position. - The fastener F (see
FIG. 9C ) is then inserted rotatably and or translationally in the hook H using again the screwdriver bit B inserted in the hook H, or manually by translationally inserting the fastener F in the hook H. In fact, the fastener F must translationally advance alongarrow 104 through thecruciform opening 16 defined in thehook fixture 12 and through thehole 32 defined in acylindrical member 34 that connects theposts 22 to theblades 24. In fact, theposts 22 and thecylindrical member 34 are integral and form a toggle support for thetoggle bolt 18. - The advancement of the fastener F will cause the
toggle member 18 to longitudinally displace in a same direction and along theposts 22. Once the ridges o28 of theposts 22 become disengaged from thechannels 30 of thetoggle bolt 18, a further advancement of the fastener F will cause thetoggle bolt 18 to pivot along arrow 106 (FIG. 9C ) as the tip of the fastener F travels along a sloped proximal portion 36 (seeFIGS. 5 and 9A to 9E) of thetoggle bolt 18. The fastener F thus causes thetoggle bolt 18 to pivot from its original position parallel to theposts 22 to a transversal position thereof shown inFIGS. 1 and 9D . - As seen in
FIGS. 9C and 9D , thetoggle bolt 18 is configured such that the fastener F, which is driven by a screwdriver bit (not shown), then threadably engages (and taps) a cruciform opening 38 (seeFIGS. 5 to 7 and 9A to 9E) defined in thetoggle bolt 18. - As illustrated in
FIG. 9E , once the fastener F is prevented from further translational advancement, for instance as a result of its head abutting thehook fixture 12, further rotation of the fastener F alongarrow 108 will gradually draw the transversally-orientedtoggle bolt 18 translationally along theposts 22, as perarrow 110, until aplane surface 40 of thetoggle bolt 18 firmly engages a non visible surface N of the wall W, whereat thehook fixture 12 is held strongly against a visible surface V of the wall W, with the hook H being strongly mounted to the wall W as the wall W is imprisoned between thetoggle bolt 18 and thehook fixture 12. - If one wishes to install the
hook fixture 12 to a rigid structure instead of to the friable wall W, theanchor 10 can be bent with respect to thehook fixture 12 such as to snap off therefrom atfrangible connections 14 as seen inFIG. 10 , i.e. at the proximal ends of theblades 24, between which there is defined aspace 26. Thespace 26 allows for the back-and-forth bending alongarrows 112 of theanchor 10 relative to thehook fixture 12, as illustrated in phantom lines inFIG. 10 . Theanchor 10 is then discarded and the remaininghook fixture 12 can be secured to the rigid structure using an appropriate fastener, such as a wood screw S when thehook fixture 12 is installed to a wooden structural member M, e.g. a 2″×4″, as seen inFIG. 11 . - Other anchoring members (i.e. instead of the
toggle anchor 10 illustrated herein) can be contemplated, as long as they are frangibly connected to the visible fixture (herein shown as hook fixture 12) and as long as they are suited to friable walls. For instance, the wall anchor disclosed in aforementioned U.S. Pat. No. 5,944,295 (that is used to secure a hook to a wall) could be adapted by removing its proximal head and by then being frangibly connected to a wall fixture such as thepresent hook fixture 12. In such a case, there would be no toggle bolt and generally no fastener, but simply a wall anchor suitable for friable walls that would be installed with its attached fixture via a screwdriver bit and as per a single step similar to that illustrated herein inFIG. 9A . If the fixture needs to be installed to a rigid structural component, the wall anchor would be snapped off from the fixture and the fixture alone would be mounted to such a rigid structural component via a threaded fastener, e.g. a screw, in a manner similar to that illustrated inFIG. 11 .
