DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

Figs. 1 to 3 Illustrate an anchor assembly A In 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 referred to as tee toggle member io, 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 pivotally connected at its rear end to the toggle member 10 and is provided at its front end with a grip member 18. The strap member 12, preferably made of plastic, is of substantially semi-circular cross-section and defines a series of ratchet teeth 20 on an outside surface thereof. The collar 16 is displaceable along tee strap member 12, teat is only towards the toggle member 10, the collar 16 Including Inner locking elements 21 (Figs. 4 to 6) which co-act with the ratchet teeth 20 In order to prevent the collar 16 from being displaced away from the toggle member 10.

The toggle member 10 defines at a leading, i.e. rear, end thereof a threaded cutting member 22 defining a pointed end and cutting edges 24 for cutting through a friable wall W material when the toggle member 10 Is rotated using, for Instance, a screwdriver while the toggle member 10 is in its position shown in Fig. 1, that is in a generally aligned

- 6 2019232840 18 Sep 2019 position thereof with respect to the strap member 12. In fact, the toggle member 10 does not have to be in the aligned position at least during

Insertion of the threaded cutting member 22 into the well W, and generally until the forward end of the strap member 12 abuts, or is close to, the visible side of the wall W.

Accordingly, a proximal, l.e. trailing, end of the toggle member 10 defines a cruciform recess 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 bits or by io 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 latter is aligned, as In Fig. 1, with the strap member 12, such that once the toggle member 10 has been inserted completely through the wall W, 15 the spring-loaded tab 28 blasedly 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 side of the wall W when the strap member 12 is pulled on.

Accordingly, when it Is desired to install the anchor assembly A 20 In the wall W, the toggle member 10 is substantially brought Into alignment with the strap member 12, as shown in Fig. 1. Then, a suitable tool, such as a screwdriver or a power driven screwdriver bit, Is engaged in the cruciform recess 26 of the toggle member 10 and Is then rotated such that die cutting member 22 of the toggle member 10 defines a hole in the wall W. Once the 25 toggle member 10 has been inserted completely through the wall W. the spring-loaded tab 28 of the strap member 12 swings the toggle member 10 to Its transversal position shown in Figs. 2 and 3, that Is generally perpendicular to the strap member 12.

The strap member 12 is then pulled away from the wall W, such 30 that the pointed teeth 30 of the toggle member 10 engage the hidden surface

2019232840 18 Sep 2019 of the 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 18 is inserted tn the hole defined in the wall W, and a flange 34 of the collar 16 abuts the visible side of the wall W. The grip member 18 Is held onto by the user while the collar 16 is displaced towards the wall W. The collar 16 is slid longitudinally along die strap member 12, and without being able to rotate with respect to the strap member 12 as a result of the ^on-circular opening 36 defined in the collar 16, which defines shoulders 37 (Ags. 1 to 3) that are engaged by the longitudinal edges 39 of the strap member 12, as best seen In Fig. 1.

Once the wall W Is firmly imprisoned between the toggle 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 collar 16, can be discarded, for Instance, by cutting or, as In the present 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 defined In the collar 16, within a semi-circular channel 38 defined longitudinally along the strap member 12, and through an opening 40 defined 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 assembly A which Itself Is firmly secured to the wall W, as explained hereinabove. If the opening 40 is provided with a machine top, a bolt can be used as me fastener, if the fastener is provided at its head, for instance, with a hook, the anchor assembly A can be used In a ceiling.

Also in accordance with the present invention, Figs. 14 to 16 Illustrate a variant anchor assembly A’, which is similar to the anchor assembly A of Fig. 1, whereby in the following description and drawings that pertain thereto, components of anchor assembly A' which are identical In

- Θ function and identical and/or similar In structure to corresponding components Of anchor assembly A of Fig. 1 (and Figs. 2 to 13) bear the same reference as In Fig. 1 (and Figs. 2 to 13), but are tagged with the prefix *’Γ and are thus in the hundreds with the last two digits thereof being Identical to the reference numerals of corresponding components of anchor assembly A. New components (or components not Identified for anchor assembly A) provided In anchor assembly A* start at reference numeral 142.

Generally, both anchor assemblies A and A' are very similar, except for their toggle members, as explained hereinbelow. The anchor assembly A¹ Is also adapted to be mounted to a wall for use with 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 pivotally connected at pivot 114 to the toggle member 110, and a locking member, such as collar 116. The strap member 112 Is thus pivotally connected at its rear, leading, end to the toggle member 110 and Is provided at Its front end with a grip member 118.

The strap member 112, preferably made of plastic, is of substantially semi-circular cross-section and defines a series of ratchet teeth 120 on an outside surface thereof. The collar 116 Is displaceable along the strap member 112, that is only towards the toggle member 110, the collar 116 Including inner locking 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 refracted back towards the grip member 118.

The toggle member 110, as opposed to the toggle member 10 of the anchor assembly A of F®. 1, does not define at a leading end thereof a threaded cutting member. Therefore, in the case of the anchor assembly A’, a hole must be formed, e.g. drilled, through the wall before the anchor assembly A' can be mounted thereto, as will be explained in more detail hereinafter. The toggle member 110 Is of C-shaped cross-section such that an open side 142 thereof faces the colter 116, when the toggle member 110 is in the transversal retention position thereof shown In Figs. 14 to 16.

A spring-loaded tab 128 is provided at the rear, i.e. leading, end of the strap member 112 such as to be engaged by the toggle member 110 when the latter is aligned with the strap member 112 (this position is generally shown in Fig. 1 with respect to anchor assembly A). Therefore, with the toggle member 110 and the strap member 112 in such a generally aligned Insertion position, the toggle member 110 can be inserted through the well,

Once the toggle member 110 has been introduced completely past the hidden surface of the wall, the spring-loaded tab 128 biasedly releases the toggle member 110 to Its transversal retention position shown In Figs. 14 to 16, The tab 128 Indudes 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 Figs. 14 to 16} the toggle member 110 to displace to its transversal retention position. Parallel and more importantly coplanar linear edges 146 of the toggle member 110 are adapted to bearably engage the hidden side of the wall when the strap member 112 Is pulled on.

Accordingly, with reference to Figs. 17a to I7i, when it is desired to install the anchor assembly A* in the wall W, a hole H is first formed through the wall W, using for instance a screwdriver bit B (see Fig. 17a). The toggle member 110 it then substantially brought Into alignment with the step member 112 (as seen In Figs. 17b), against the bias of the springloaded tab 128, and Is inserted completely through the wall 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 retention position shown in Figs. 14 tolS, that is generally perpendicular to the strap member 112.

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

2019232840 18 Sep 2019 slid, along arrows 150 (Fig. 17e) towards the wall W and the toggle member

110, along the ratchet teeth 120 of the strap member 112, that Is until a skirt

132 of the collar 116 is Inserted In the hole H defined in the wall W and a flange 134 of the collar 116 abuts the visible side of the wall W. The grip member 118 is held onto by the user while the collar 115 is displaced towards the wall W. The collar 116 is slid longitudinally along the strap member 112, and without being able to rotate with respect to the strap member 112 as a result of the ηοπ-circular opening 136 defined in the collar 116, which defines shoulders 137 (see Figs. 14 and 15) that are engaged by longitudinal edges io 139 of the strap member 112, as best seen In Fig. 15.

Once the wall W Is firmly imprisoned between the toggle member 110 and the collar 116, the grip member 11B 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 is present embodiment, by bending (see Fig. 17f] as the strap member 112 is provided with weakened areas which allow the strap member 112 to be separated In two, As shown In Fig. 17g, the remaining portion of the strap 112 thus connects the toggle member 110 to the collar 116 within the hole H in the wall W

Q 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-circular channel 138 defined longitudinally along the strap member 112, end 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 anchor assembly A* which itself is firmly secured to the waff W, as explained hereinabove. If the opening 140 defines a machine tap (as in Figs. 17a to 171), the bolt S can be used as the fastener. If the fastener Is provided at its head, far instance, with a hook, the anchor assembly A' can be used In a celling. Here, the bolt S Is used to mount a hook fixture F to the wall W, as seen in Figs, 17g to 17h.

Although the present invention has been described hereinabove by way of specific embodiments thereof, It can be modified, without departing from the spirit and nature of the subject Invention pg defined in the appended claims.
