Description:
A FOLDING ANCHOR

FIELD OF THE INVENTION

The present invention relates to the field of anchors used to fasten an object to a surface of a panel.

BACKGROUND

Anchors are attached to panels by different designs and methods. Typically, anchors are consisted of a fastening receiver such as a nut attached to an anchor body. A fastening rod such as a screw or a bolt is fastened into the fastening receiver and forces applied on the fastening receiver are transmitted and distributed by the anchor body to a contact area of the panel. Counter forces generated by the panel counteract the forces transmitted to the panel. Most anchors are inserted through an insertion hole made in the panel. Some anchors are attached to the hole itself as they expend inside while other anchors use the back surface of the panel to counteract forces apply on them.

SUMMARY OF THE INVENTION

The folding anchor is built from at least two consecutive members inserted through an insertion hole of the panel from the first member to the last member. Each two consecutive members are coupled by means for repositioning one member relatively to the other. Initially, those two consecutive members are positioned away from each other for the insertion through the insertion hole, but as the leading member of the two consecutive members passes the thickness of the panel and enters the space behind the panel, it repositions towards its trailing member. This process folds the anchor behind the panel. The last member is mounted into the insertion hole and thereby it controls the final position of all the members of the anchor behind the panel. A member that is not the last member comprises a fastening receiver such as a nut. A fastening rod such as a screw or a bolt is inserted through the insertion hole is fastened into the fastening receiver. A stack of contiguous members having at least the one member comprises the fastening receiver is contiguous to a portion of the back surface of the panel and transmit and distribute pulling forces applied by the fastening rod on the fastening receiver to the panel. The panel generates counter forces that counteract those pulling forces.

A common means for repositioning is a pivoting axis. A pivoting axis couples two consecutive members rotates the leading member relatively to its trailing member. A spring can be used to rotate members to theirs final position but gravity can be used as well. The pivotal axis between two members does not have to be positioned at the very end of the members. The pivotal axis could be positioned at other points along the members as long as the leading member can rotate in the space behind the panel and fulfill its function.

Another means for repositioning is an elastic connector coupling two consecutive members. This type of means for repositioning is especially useful for inexpensive anchors and could be made of materials such as metal, plastic and nylon.

Other means for repositioning include but not limited to combinations of several pivoting axes, sliding mechanisms, ball and socket joint mechanisms and combination of means.

In a simple embodiment, the anchor is built of two members coupled by a pivotal axis. The anchor is inserted in its unfolded form. Once the first member passes the thickness of the panel and reaches the space behind the panel, it rotates against the second member, which is the last member of the anchor. The last member of the anchor comprises means for mounting including a ring that mounts into the insertion hole and a disk that lays against the frontal periphery of the insertion hole, thereby, the second member is controlling the position of the first member behind the panel. In other embodiments, the anchor is built of three members or more. Each two consecutive members are coupled by means for repositioning. The anchor is inserted in its unfolded form. Once the first member passes the thickness of the panel and reach the space behind the panel, it rotates against the second member of the anchor. Then as the second member passes the thickness of the panel, it also rotates against the third member and so forth. The last member of the anchor has means for mounting in the insertion hole. This last step controls the final position of the members behind the panel.

In yet other embodiments, at least one member of the folding anchors further comprises an additional at least one sub-member and means for repositioning. In one of the embodiments, once the sub-member passes the thickness of the panel and reaches the space behind the panel, the sub-member turns in about 90 degrees to the originating member and creates a cross-like structure that further increases the contact area between the folding anchor and the back surface of the panel.

In additional embodiments, at least one member of the folding anchor further comprises an additional at least one sub-member that is branching away from the member by means for repositioning such as a pivotal axis to further increase the contact area with the back surface of the panel.

Yet other embodiments further include means for initiating the fold. Members of the anchor are inserted in their unfolded position. Said means for initiating the fold is responsible folding said members to their final positions. The timing of the fold is decided and timed by the operators. An example for means for initiating the fold including a triggering hook that is released and allowing the elastic folding of said members of the anchor. Another example is a pull back means that folds the members of the anchor behind the panel. Embodiments may further combine means for preventing rotation of the fastening receiver and/or any other member that is subjected to shear forces generated by the threading of the fastening rod into the fastening receiver. Means for preventing rotation may further wedge into the back surface of the panel and prevent damage and distortion of the folding anchor.

The current disclosure is also a novel method of inserting an anchor into a panel. The first step of the method is creating an insertion hole in said panel in a predetermined size and location for the insertion of the folding anchor. The next step is insertion of the members of the folding anchor consecutively from a first member to a last member. Each subsequent member of the folding anchor pushes each leading member into a space behind the panel where the leading members fold into their final position. The next step is mounting the last member into the insertion hole and essentially establishing the final position of all the members of the folding anchor. The next step is insertion of a fastening rod that is fastened into a fastening receiver of the folding anchor. The fastening rod transmits pulling forces to said fastening receiver and from there, the pulling forces are transmitted and distributed via a stuck of at least one member a portion of the back surface of the panel. The panel generates counter forces that counteract the pulling forces

The different embodiments and methods disclosed in this application are just some examples to the host of implementations and combinations possible with the novel concept of the folding anchor. Some features, options, and advantages may be shown in certain embodiments but may not be shown in other. And yet, any part of the subject matter of the present invention may be combined in any suitable manner in one or more embodiments, designs and/or

implementations. Any part of the present disclosure may be also incorporated into existing anchors. Furthermore, designs, structures, materials, features or operations may not shown or described in detail to avoid obscuring aspects of the subject matter of the present disclosure. The current disclosure describes the principals, concepts, details, designs, features, methods, structures, characteristics and/or advantages of the novel anchor so that anyone skilled in the art can understand and implement either all or any part of the subject matter. The features and advantages of the subject matter of the present disclosure will become more fully apparent from the following description and appended claims, or may be learned by the practice of the subject matter as set forth hereinafter.
