Description
HIGH STRENGTH ANCHOR ASSEMBLY FOR FASTENER
DESCRIPTION
Technical Field
This invention relates to improved blind anchor¬ ing devices for fastening objects to hollow walls with elongated fastener members such as screws, bolts and the like.
Background Art
The present invention relates to an improved anchor assembly of the type generally described in United States Patent No. 4,075,924 issued to Thomas McSherry et al. on February 28, 1978. The '924 patent describes an anchor assembly comprising a pair of elongated leg members of flexible material and an elongated anchor member coupled to adjacent end portions of the legs. The legs are shown spaced apart along the long dimension of the anchor member. The leg members include resilient means such as transversely bent end portions to resil- iently bias the anchor member generally transversely to the legs.
In use, the flexible legs are bent so that the long dimension of the anchor member is oriented along the legs and the anchor is inserted into a hole in a wall or ceiling. The transversely bent end portions of the legs then bias the anchor member back to its trans¬ verse position, and suitable collar means are slipped up the legs to sandwich the wall between the anchor and the collar.
While this anchor assembly is highly useful for many applications, the presence of resilient biasing
means, such as the bent end portions of the legs, and the need for leg flexibility, tend to limit the maximum strength available in the legs of the device.
Another form of anchor assembly is described in United States Patent No. 4,043,245 issued to Stanley Kaplan on August 23, 1977. In the Kaplan device, the legs are spaced apart across the narrow dimension of the anchor member and each leg is coupled to only one side of the anchor member via a trunion inserted into an apertured flange.
The difficulty with this structure is that each leg is held to the anchor member on only one side. Nothing forces the trunion into the aperture and if it pulls out, the leg comes off. Moreover, the spacing of the legs across the narrow dimension of the anchor member limits the minimum size of the anchor and hence requires larger holes in the wall.

Best Mode For Carrying Out The Invention
A. Slotted Anchor Member Embodiment (Figs. 1A, IB, and 1C)
Referring to the drawings, FIG. 1A illustrates a preferred anchor assembly in. accordance with the inven¬ tion with its component parts shown separately for pur¬ poses of the description. The anchor assembly 10 com-
prises a pair of elongated substantially straight legs 11. The legs 11 are preferably constructed of a resilient material such as plastic or metal which is relatively rigid although it can be elastic for lower strength devices. The legs 11 have opposing serrated surfaces comprised of a plurality of adjacent teeth 12.
The lower end portions 13 of the legs are con¬ nected by a bridge 14 and preferably a pulling ring 15 is constructed integrally with the bridge to provide firm control of the legs as will be described.
The upper end portions 16 of each of legs 11 terminates in a coupling stud 17 extending parallel with the major transverse surface of each respective leg.
These studs permit coupling of the legs to channel member 18.
Channel member 18 is preferably comprised of metal, such as steel plate, and has a channel-like cross sectional configuration with a central plate sectio 19 and flanges or end plates 20 extending downwardly therefrom. The flanges may be right-angled with respect to the central plate; however, by constructing them at an angle somewhat less than 90", e.g. 80% , the anchor member will resist greater compressive forces than if the flange were perpendicular to the central plate.
The central plate preferably defines an open- ing 21, such as a threaded opening, for receiving elon¬ gated fastener members such as bolts or screws.
Flanges 20 are each provided with a pair of coupling apertures 21A and 21B for receiving the project- ing ends of coupling studs 17. The stud of each leg
O
preferably extends across the minor dimension of channel member 18 and extends into corresponding aligned apertures in each of the two transverse flanges 20. Preferably one such aperture is a circular aperture 21A of substantially the same diameter as the stud and the other is an elon¬ gated slot 21B for permitting motion of one coupled leg toward and away from the other leg.
The collar 22 is comprised of a generally planar base 23 having flanges 24 extending upwardly therefrom. These flanges 24 and the base 23 are con¬ structed integrally and are preferably of resilient material such as plastic.
The upstanding flanges 24 define slots 25 within which are provided oppositely positioned teeth members 26. The slots 25 communicate with tapered chan¬ nels 27 which conveniently guide the leg members 11 toward the slots 25 for the purpose of completing the assembly of the collar 22 and legs 11.
The assembly is conveniently fabricated by injection molding the ring and leg assembly of the resil¬ ient material having memory with the legs in spread apart position as shown in Fig. 1C; injection molding the collar; and forming the channel with the flanges at an angle somewhat less than the final angle. The channel is then positioned over the upper end portion of the legs spaced apart along the major dimension of the anchor member with apertures 21A and 21B aligned with studs 17. The flanges are then bent to the final angle, engaging each of the studs on both sides of the channel member.
The anchor assembly is conveniently utilized in wall openings dimensioned less than the length of
channel member 18. As shown in Fig. IB, insertion of the channel member 18 into the wall opening is facilitated by the fact that with the coupling arrangement used, the channel member can be rotated about the stud in circular apertures 21A until it is substantially in line with the longitudinal dimension of legs 11. After the channel member clears the concealed surface of the wall, it is released, and the tendency of legs 11 to spring apart returns the channel to its transverse position,, as shown in Fig. 1C.
The attachment of the anchor assembly is com¬ pleted by sliding the collar 22 about the leg members 11 such that a ratcheting engagement occurs between the teet 12 of the legs and the teeth 26 of the collars. The legs are then pulled through the collar until the wall is effectively sandwiched between the collar and the channel member 18. The excess portions of the legs can be cut" away, and a fastener can be inserted through the collar and engaged to the channel member, as by threading.
The combination of straight legs and transverse studs coupling to both sides of the channel substantially enhances the load-carrying capability of the assembly. Moreover, the provision and use of the slotted aperture coupling arrangement permits the use of stronger, rela¬ tively rigid legs because the ability of the stud to slide in the slot minimizes the need for flexibility during the process of insertion into a wall.
As a less preferred form of the invention, slots 21B in the flanges 20 can be replaced by a slot in the central plate section 19 and a leg can be slidably engaged therein by conventional trunion coupling rather than by coupling studs. Such a structure has the
OM
advantage of permitting the use of relatively rigid leg materials, but its coupling is not as great as is obtained by the use of studs.
Figs. 2A and 2B illustrate an alternative embodiment of the invention similar to that of Fig. 1A except that that both coupling apertures 21A and 2B are approximately the same diameter as the coupling stud 17.
Fig. 2B shows the structure in position for insertion into a wall opening. The anchor is rotated about one stud, e.g. 21A, to displace downwardly and outwardly the opposite leg 11. The displaced leg, which is attached to leg 11A at the opposite end, develops a spring-like force opposing the rotation, and when the anchor passes through the opening, the resilient force applied by leg 11B will snap the anchor back to the transverse position.
The advantage of this structure, as compared with prior art structures using bent-end legs, is that th resilient force for snapping the anchor back into trans¬ verse position is generated over a relatively large radius of curvature. This fact permits the use of relatively frangibly plastic materials for the legs, such as poly¬ styrene, which can be readily broken off after the wall has been sandwiched between the collar and the anchor. Such frangible materials can be broken off by a manually applied sharp bend without the use of additional tools.
Fig. 3 illustrates an alternative form of the invention which substitutes smooth legs 30 for the sawtoothed legs of the Fig. 1 embodiment and an attached base 31 defining aperture 32 for the collar member of
Fig. 1. Preferably legs 30 are provided with the hinge means in the form of relief notches 33 for permitting the to fold between flanges 20 of channel member 18, as the wall is sandwiched between base 31 and the collar member by a fastener (not shown) .
Figs. 4A and 4B illustrates yet another alter¬ native embodiment of the invention. This embodiment, suitable only for low stress applications, differs from that of Fig. 3 in that an apertured solid plastic bar 40 is substituted for the channel member 18, and the bar 40 is attached to legs 30 by bonding across its minor dimen¬ sion rather than through the use of coupling studs and apertures. Optional antirotation fins 41 are shown advantageously disposed on base 30 or attached by me¬ chanical techniques.
This device is conveniently fabricated by molding as a unitary structure in the form shown in Fig. 4B. Here the plastic anchor bar is integrally molded to the leg members in an angularly offset posi¬ tion. After molding, the bar 40 is rotated onto the legs and bonded thereto by thermal or ultrasonic bonding techniques.
While the invention has been described in connection with a small number of specific embodiments, it is to be understood that these are merely illustrative of the many other specific embodiments which can also utilize the principles of the invention. Thus numerous and varied devices can be made by those skilled in the art without departing from the spirit and scope of the present inven¬ tion.
