DESCRIPMON OF THJE ILLUSTRATV EM LDMETS

Figs. 1 to 3 llustrate an anchor assembly Ain accordance with the present Invention, which Is adapted to be mounted to a wall W for use with a fastener (not shown), such as a screw. The anchor assembly A comprises a cutting and retention member 10 hereinafter rferred to as the 1s toggle member 10, a strap member 12 pivotally connected at pivot 14 to the toggle member 10, and a locking member, such as collar 16. The strap member 12 Is thus pivotlly connected at its rear end to the toggle member 10 and is provided at Its frot end with a gip member 18. The strup member 12, preferably made of plastic, is of substanaly semi-circular crss-section and defines a series of ratchet teeth 20 on an outsidesurface thereof. The collar 16 is displaceable along the strap member 12, that is only towards the toggle member 10, the collar 16 including Inner locking elements 21 (Figs. 4 to 6) which co-act wihthe ratchet teeth 20 In order to prevent the coNr 16 from being displaced away from the toggle member 10.

The toggle member 10 defines at a leading. Le- rear, end thereof a threaded cutting member 22 defining a pointed end and cutting edges 24 for cutting through a table wall W matedal when the toggle member 10 is rotated using, for Instance, a screwdriver while thetoggle member 10 Is in its position shown in Fig. 1, that is in a generally aligned position thereofwith respect t the strap member 12. In fact, the toggle member 10 does not have to be in the signed position at least during Insertion of thetreaded cutting member 22 Into the wall W, and generally until the forward end of the strap member 12 abuts. or is dose to, the visible side of the wall W.

Accordingly, a proximal,. Le. trailing, and of the toggle member 10 defines a crucform recss 26 adapted to be engaged by a Phillips-type screwdriver. It is understood that other types of female recesses or even male extensions. engageable respectively by suitable screwdrIver bts or by 1o suitable rotatable sockets, could also be used.

A spring-loaded tab 28 Is provided at the rear, i.e. leading. end of the strap member 12 such as to be engaged by the toggle member 10 when the later is aligned, as In Fig. 1, withthe strap member 12, such that once the toggle member 10 has been inserted completely through te wall W, s the spring-loaded tab 28 biasedly releases the toggle member 10 to its transversal retention position shown in Fig. 2. The toggle member 10 also includes pointed teeth 30 adapted to engage the hidden Bide of the wall W when the strap member 12 is pulled on.

Aooordingly, when it Isdesired to install the anchor assembly A in the wall W, the toggle member 10 is substantially broughtInto alignment with the strap member 12, as shown in Fig. 1. Then, a suitable tool, such as a arewdriver or a power driven screwdriver bit is engaged in the cruciform recess 28 of the toggle member 10 and is then rotated such that the cutting member 22 of the toggle member 10 defines a hole in the wall W. Once the toggle member 10 has been Inserted completely through the wall W. the springaoaded tab 28 of Me strap member 12 swings the toggle member 10 to its tranuversal position shown in Figs. 2 and 3, thatIs generally perpendicular to the strap member 12.

The strap member 12 is then pulled away from the wall W, such that the pointed teeth 30 of the toggle member 10 engage the hidden surface of 1he wall W. The collar 16 is then slid towards the wall W along the ratchet teeth 20 of the strap member 12 that is until a skirt 32 of the collar 15 Is inserted in the hole defined in the wall W, and flange 34 of the collar 16 abuts the visible side of the waft W. The grip member 18 Is held onto by the user while the colar 16 Is displaced towardsthe wall W. The collar 16 is slid longitudinally along the strap member 12, and without being able to rotate with respect to the strap member 12 so a result of the non-circular opening 36 defined in the collar 18, which defines shoulders 37 (Figs. I to 3) tt are engaged by the longitudinal edges 3 of the strap member 12, as best seen In Fig. 1.

Once the wall W Is firmly Imprisoned between the oggle member 10 and the collar 16, the grip member 18 and the section of the strap member 12 extending between the grip member 18 and the flange 34 of the calar 16, can be discarded, for Instance, by cutting or, as In the present 1s embodiment, by bending as the strap member 12 Is provided with weakened areas which allow the strap member 12 to be separated in two. The remaining portion of the strap 12 thus connects the toggle member 10 to the collar 16 withIn the hole in the wall W.

A fastener can then be engaged through the central opening 36 2o defined In the collar 16, within a semi-clular channel 38 dened longitudinaly alongthe strap member 12, and through an opening 40 dened In the toggle member 10. The opening 40 in the toggle member 10 may be, for instance, tapped by the fastener such that the fastener becomes firmly secured to the anchor ssmby A which itselfIs fmly secured to the wall W, as explained hereinabove,if the opening 40 is provided with a machine top, a bolt can be used as the fastener. If the fastener is provided at its head, for instance, with a hook, the anchor assembly A can be usedIn a ceing.

Also in accordance with the present invention, Figs. 14 to 16 ilkastrate a variant anchor assembly A, which is sinNar to the anchor assembly A of Fig. 1, whereby in the following description and drawings that pertain thereto, components of anchr assembly A' which are identical In function and identical and/or similar in structure to corresponding components of anchor assembly A of Fig. I (and Figs. 2 to 13) bear the same refereno as In Fig. 1 (and Figs. 2 to 13), but are taggedwith the prefix "1" and are thus In the hundreds with the lasttwo digit thereof being Identical to the reference s numerals of corresponding components of anchor assembly A. New components (or components not Identified for anchor pesembly A) provided In anchor assembly N start at reference numeral 142.

Generally,both anchor assemblies A and A are verysimilar, except for their toggle members, as explained hereinbelow. The anchor 1o assembly A Is also adapted to be mounted to a wall for useWth a fastener (not shown), such as a screw. The anchor assembly A comprises a retention member 110 hereinafter referred to as the toggle member 110, a strap member 112 plvotaly connected at pivot 114 to the oggle member 110, and alocidng member, such as collar 116. The strap member 112 is thus pivotaly is connected at its rear, leading, end to the toggle member 110 and is provided atIts front end with a grip member 118.

The strap member 112, preferably made of plastic, Is of substantially semi-cdrcular oses-section and defines a series of ratchet teeth 120 on an outside surfacethereof. The collar 116 Is displaceable along the strap member 112. that is only towards the toggle number 110, the collar116 including Inner looking elements (not shown) which co-act with the ratchet teeth 120 in order to prevent the collar 116 from being displaced away from the toggle member 110, i.e. from being retracted back towards the grip member 11e.

The toggle member 110, as opposed to the toggle member 10 of the anchor assembly A of Fig. 1, does not define at a leading end thereof a threaded cutting member. Therefore, in thecase of th anchor assembly A', a hole must be formed, e.g. drilled, through the wall before the anchor assembly A' can be mounted therto, as wil be explained in more detail hereinafter. The toggle member 110 Is of C-shaped cross-section such that an open side 142 thereof facesthe collar 116, when the toggle member 110 is in the transversalreention position thereof shown In Figs. 14 to 16.

A spdng-loaded tab 125 is provided at the ear. I.e. leading, end of the strap member 112 such as to be engaged by t toggle member 110 s when the latter is signed with the strap member 112 (this position is generally shown in Fig. I with respect to anchor assembly A). Therefore, with the toggle member 110 and the strap member 112 in such a generally alignedinsertion posidon, Ihe toggle member 110 can be Inserted through the wall.

Once the toggle member 110 has beenintroduced completely 1o past the hidden surface of the wal, the spring-loaded tab 128 basedly releases the toggle member 110 toIts transversal retenton position shown In Figs. 14 to 16. The tab 128Includes a V-shaped tongue 144 that is forcibly folded or collapsed when the toggle member 110 is brought to the insertion position and that causes, as it plastically returns to Its at-rest position (see Fig. 14 to 1) the togglemember 110 to displace to its transversal retenon position. Parallel and more Importantly co-planar linear edges 146 of the toggle member 110 are adapted to bearably engage the hidden side of the wa when the strap member 112Is pulled on.

Accordingly, with reference to Fig. 17a to 17, when it is 2o desired to install the anchor assembly A in the wall W. e hole H is gret fmed through the wall W, using for instance a scrwdriver bit B (see Fig, 17). The toggle member 110 isthen substantially brought Into lignment with the strap member 112 (as see In Figs. 171), against the bias of the spring loaded tab 128. and toInserted completely through thewall W (see Figs.17c and 17d). In Fig. 17d the spring-loaded tab 128 of the strap member 112 swings the toggle member 110 to its transversal retenton position shown in FIgs. 14 toi6, thatil generally perpendicular to the strap member 112.

The strap member 112 I then puned away from the wall W, along arrow 148 in Fig. 17e, such that the linear edges 146 of thetoggle member 110 engage the hidden surface of the wall W. The collar 116 is then

Wd, along arrows 150 (Fig. 17e) towards the wall W and the toggle member 110, along the ratchet teeth 120 of the strap member 112, thatIs until a shirt 132 of the collar 116 Is inserted In the hole H defined in the wall W and a flange 134 of the colr 116 abuts the visible side of the wall W. The grip s member 118 is held onto by the user while the color 11 is displaced towards the wall W. The collar 116 isslid longitudinally along the strap member 112, and without beingable to rotate with respect to the strap member 112 as a result of the non-circular opening 136 defined in the collar 116, which defines shoulders 137 (sep Figs. 14 and 15) tot are engaged by longitudinal edges -1 139 of the strap member 112, as best seen In Fig. 15.

Once the wall W Isfirmly imprisoned between the toggle member 110 and the collar 116, the grip member 118 and the section of the strap member 112 extending between the grip member 118 and the flange 134 of the collar 116, can be discarded, for instance, by cutting or, as in the present embodiment, by bending (see Fig- 17) as the strap member 112 is provided with weakened areas which anow the strap member 112 to be separatdIn two. As shownIn Fig. 17g, the remaining portion of thestrap 112 thus connects the toggle member 110 to the collar 116 wIthin the hole H In the wall W.

Still referring to Fig. 17g.a fastener, such as a screw or a bolt S, can then be engaged through the central opening 136 defined In the collar 116, withIn a semi-curular channel 138 defined longitudinaly along the strap member 112 and through an opening 140 defined in the toggle member 110. This opening 140 in the toggle member 110 may be, for Instance, tapped by the fastener such that the fastener becomes firmly secured to the ancW assembly A which itself is firmly secured to ihe wall W, as explained hereinabove. If the opening 140 defines a machine tap (as in Figs. 17 to 17),the bolt S can be used as the fastener. If the flstener is provided at Its head, for instance, with a hok, the anchor assembly A' can be used In a 3o ceiling. Here, the bolt 8 is used to mount a hook fixture F to fth wall W, as seen in Figs. 17g to 17h.

Although the present invention has been described hereinabove by way of specifg embodiments thereof, it can be modified,without departing from the spirit and nature of the subjectInvention ms defined in the appended claims.
