DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0026] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these specific details. In other instances, well- known methods, procedures, and components have not been described in detail so as not to obscure the present invention. As an example of a well-known method, one can use (together with the present invention or without it) a pulley or a block and tackle.

[0027] In order to enable easy and safe means and method for anchoring and securing heavy and / or large objects to high locations benefit is taken, according to embodiments of the present invention, of the fact that a small and light-weight anchoring element may be carried safely and easily by a single person to any desired high securing location, may then be secured, and then enable pulling by a lightweight, thin and strong enough rope, a connecting element from the base level towards the anchoring element, until the connecting element reaches the anchoring element and securely attached to it. Any heavy and/or large object that is attached to the connecting element is easily pulled by the rope and when the connecting element is securely locked to the anchoring element, thereby forming an anchoring apparatus, the load or object are properly secured, due to the fact that the anchoring element is well secured at the high. The rope may be selected to be as light weight as possible and still adapted to withstand sufficient pulling force to pull up the load / object that need to be secured and anchored. According to some embodiments the rope may be pulled from the ground /base level, after the anchoring element has been properly attached to the high/remote location. According to this embodiment during installation of the anchoring element the only weight that has to be carried by the person installing the anchoring element is that of the anchoring element itself and the self-weight of the rope with length of less than twice the distance of the anchoring point from the ground / base.

[0028] A remote anchoring apparatus according to embodiments of the present invention may comprise of two main elements, an anchoring element and a connecting element. The anchoring element is designed to be relatively light weight and have relatively small physical dimensions to enable easy carrying and anchoring onto support structure or construction at high locations. The anchoring element is formed with a reception section adapted to self-lead a corresponding portion of the connection element when the connecting element is inserted into the anchoring element. The connecting element is formed with an insertion section adapted to enable the connecting element to be self-lead into the reception section of the anchoring element. The connecting element is further adapted to be securely lock to the anchoring element after it was self-lead into the reception section of the anchoring element. The term "self-lead" as used here relates to operations that does not require direct manual intervention by a human, but rather may be operated from remote.

[0029] According to some embodiments the connecting element may be lead towards the anchoring element, may be inserted into the reception section of the anchoring element and the locking feature may be activated - all or part of which - solely using a pulling rope operated (i.e. pulled) from remote, as is explained in details below.

[0030] Reference is made to Fig. 1, which is a schematic perspective drawing of anchoring apparatus 1 shown in position in which connecting element 3 is engaged with anchoring element 2, in an elevated view, according to embodiments of the present invention. According to embodiments of the invention the position shown in Fig. 1 is obtained, for example, when connecting element 3 has been inserted into the reception section of anchoring element 2 and was locked to it, as explained below in details.

[0031] Reference is made now to Figs . 2 and 3, which are a schematic perspective drawings of anchoring element 3 of Fig. 1 in an elevated view and in a lowered view, respectively, according to embodiments of the present invention. Anchoring element 3 may be formed as unit having hanging or attachment arrangement, or means 26 at one end denoted top end and opening 21 at its opposite end, denoted bottom end. Opening 21 may form the entrance to reception section 20A formed as a hollow space in the body of anchoring element 2. Opening 21 is encircled by bottom circumference element 20B. Between reception section 20 A and anchoring means 26 pulling rope hole (PRH) 25 is located preferably centralized along central axis CA. PRH 25 is formed in bridging element 24 extending from one side to an opposite side of anchoring element 2. Bridging means 24 leaves space between it and anchoring means 26 so as to enable a rope (or similar cable, chain or any other flexible pulling means) to be inserted through PRH 25 from the bottom side, to be bent sideways when exiting hole 25 from the top side and extend outside of anchoring element 3 and to be pulled therefrom. According to embodiments of the invention locating PRH 25 substantially centered around central axis CA is required in order to ensure uninterrupted insertion of connecting element 3 through opening 21 and/or secured locking of connecting element 3 to anchoring element 2, as is explained in details below. [0032] The exact size of anchoring element, the materials it is made of, the size of anchoring means hole 26, the size of PRH 25, the space left for a rope exiting PRH 25 upwardly for bending sideways, etc. may be determined according to requirements exerted on remote anchoring apparatus 1, such as the maximal expected load it should be adapted to stand, during lifting the load towards anchoring and later during use of the anchored load, the maximal weight of the anchoring element 2 to allow easy and safe carrying up of anchoring element 2 toward the anchoring point, etc. Under such design requirements light weight and strong material may be chosen, some volume of material the anchoring element 3 is made of may be removed, for example cavities 20C, so as to maintain at least minimal load carrying capacity while using only the required amount of mass of anchoring element 2.

[0033] Anchoring element may be adapted to be anchored, or attached to a support structure or object via anchoring, or hanging means 26, which may be shaped, for example, as a hanging cavity or hole that enables hanging or anchoring element 3 to a support structure. Hanging means hole 26 may be located close to one end of anchoring element 2.

[0034] Reference is made now also to Fig. 4, which is a cross section view of anchoring element 2 in plane A- A (Fig. 1), according to embodiments of the present invention. Reception section 20A is circled by closed loop dashed line. Opening 21 may comprise two sectors. The outer sector may be configured as a cone with the wider end facing out of anchoring element 2 and its diameter gradually getting smaller as much as getting farther from the bottom end of anchoring element 2 towards its top end. Conical sector or sloping circumferential ring 22 is disposed at the very bottom end of opening 21 with its wider section pointing outwardly from reception section 20 A. Conical sector 22 reaches a minimal diameter DINS that is large enough to enable smooth and uninterrupted entrance of connecting element 3 into reception section 20 A. Conical sector 22 is formed to lead and enable smooth entrance of connecting element 3 into anchoring element 2, as is explained in details below. The upper, or inner end 221 of conical sector 22 ends with fiat peripheral rim 23 forming a circumferential flat ring having its face disposed in a plane perpendicular to the longitudinal axis CA, an inner opening diameter slightly bigger than the outer diameter DI_NS (Fig. 7) of connecting element 2.

[0035] Opening 21 further comprise upper edge 221 extending from the upper end of cone 22 and forming a ring-like sector. The inner diameter of the ring-like sector complies with the same requirements implied on the inner diameter of the upper end of cone 22 with respect to smooth insertion of connecting element 3. Upper edge 221 is adapted to provide stopping support to locking springy pins 35 of connecting element 3, as is explained below. The diameter of reception section 20A right above upper edge 221 is at least DLOCK which is larger than Dlock of locking springy pins 35 (see Fig. 7), to ensure safe locking of connecting element 3 to anchoring element 2 at the end of insertion.

[0036] Opening 21, ring like section and upper edge 221 and fiat peripheral rim 23 having diameter DLOCK are all made preferably with radial symmetry around longitudinal central axis CA, to enable smooth and easy insertion of connecting element 3 into anchoring element 2 indifferent of the actual relative radial angle of connecting element 3 with respect to anchoring element 2 at time of insertion of connecting element 3 into anchoring element 2.

[0037] Reference is made to Fig.5, which is a schematic side view of the anchoring apparatus of Fig. 1 as seen from the direction indicated in Fig. 1 engaged with connecting element 3 in fully engaged position, according to embodiments of the present invention. In fully engaged position connecting element 3 is securely connected to anchoring element 2 thereby anchoring hole 26 and hanging hole 36 are connected to each other thereby providing rigid connection between them, as is explained in details below.

[0038] Reference is made now to Figs. 6 and Fig. 7 which are schematic perspective elevated view and side view, respectively, of connecting element 3 of Fig. 1, according to embodiments of the present invention. Connecting element 3 may be formed, preferably, as a cylindrical object having conical shaped portion 31 at its upper end and having a diameter DINS at its lower end, the diameter is adapted to be smoothly and easily inserted into reception section 20 A via opening 21 of anchoring element 2. Conical portion 31 may have a hole 33 comprising first part 331 made through its vertex and along connecting element 3 longitudinal axis CB, extending L331 into conical portion 31, and second part hole 332 extending from a side face of conical portion 31 towards central longitudinal axis CB and meeting hole 331 substantially perpendicular to hole 331, thereby forming a continuous opening that runs through both holes. Hole 33 is adapted to enable threading of pulling means such as a rope through it so that its longer end extends out of first part hole 331 and its shorter end extends out of second part hole 332 and enabling securing the pulling means from being threaded out from hole 33 under tension, for example by making a tie at the shorter end.

[0039] Conical portion 31 ends, at its bottom end, with a cylindrical sector 34 having a diameter similar to the maximal diameter of conical portion 31. At least one springy pin 35, and preferably two or more, are disposed extending from the circumference of cylindrical sector 34 and perpendicular to the face of the cylindrical sector outwardly. Pins 35 are made each with spring that pushes the pin outwardly. Pins 35 are adapted to extend out of cylindrical sector 34, when no force is exerted on them, inwardly to reach a position in which the distance between the outer ends of two opposing pins 35 is DLOCK, which is greater than DINS. [0040] Each of pins 35 is spring loaded and is designed to extend outwardly in rest position and be pushed inwardly into the body of connecting element 2 when force is exerted on the pins directed along the longitudinal axis of the pins against the loaded spring. Each of pins 35 is adapted to retract inwardly under retracting force so that when two opposing pins are retracted the distance between their outer ends is less than DINS- Each of pins 35 has an inclined area 351 formed at its outer end which is facing to upwardly the side of cone 31 so that its outermost end is lower than its innermost end with respect to cone 31 vertex. Inclined areas 351 are made so that when force F 1 is exerted onto the inclined area it translates, due to the inclination, to perpendicular force pushing the pin into connecting element 3. Such force may be exerted, for example, when connecting element 3 is inserted into anchoring element 2 via opening 21 and pins 35 meet sloping circumferential ring 22, as is explained in details below.

[0041] Each of pins 35 may be shaped as a short cylindrical or any other longitudinal shaped object at most of its length from its inner part being in active connection with a return spring (not shown) and may have formed at its outer end inclined area 351 as explained above. The cylindrically, or elongated portion of pin 35 may extend outside of the cylindrical area of cylindrical sector 34 at length of DLOCKI as measured from the outer end of this portion of one pin to the same place on the opposite pin. The distance DLOCKI may be slightly smaller than DLOCK, and at least to some extent longer than DINS, to ensure secured attachment of connecting element 3 to anchoring element 2.

[0042] Reference is made now to Figs. 7A-7C, which schematically depict three consecutive stages of engaging connecting element 3 to anchoring element 2 from the beginning of the engagement to fully engaged position, respectively, according to embodiments of the present invention. Fig. 7A shows an initial engagement step at which connecting element 3 is pulled by a pulling force PF from the vertex of connecting element 3 into reception section 20A via opening 21. As seen in this drawing, pins 35 are just about to meet circumferential conical ring 22.

[0043] Fig. 7B shows an intermediate engagement step at which connecting element 3 is further pulled by a pulling force PF from the vertex of connecting element 3 into reception section 20A via opening 21. Pins 35 are now partially pushed inwardly into the body of connecting element 3 due to the fact that their inclined areas 351 meet now a portion of circumferential conical ring 22 with a smaller diameter, which exerts force onto pins 35 against their return springs.

[0044] When connecting element 3 is further pulled into anchoring element 2, the lower side of pins 235 passes by and exceeds the plane at which the plane of fiat peripheral ring 23 and the force of the return spring(s) causes pins 35 to extend outwardly, thereby to exceed the inner diameter of peripheral ring 23 and, as a result, to prevent pulling out connecting element 3 from anchoring element 2, unless pins 35 are again being pressed inwardly, for example by a manual intervention. It would be apparent those skilled in the art that certain elements that were described above may have different form and/or dimension as long as the opening in anchoring element 2 is made to allow the connecting element 3 to be inserted into a reception section and to be locked therein at the end of insertion. It would be apparent that the conical form of the upper (or leading) end of the connecting element 3 has an advantage since it ensures easy and uninterrupted insertion of the connecting element 3 into the anchoring element 2.

[0045] Reference is made now to Fig. 8, which is a schematic cross section view of the anchoring apparatus of Fig. 1 , made in plane A-A indicated in Fig. 1 , according to embodiments of the present invention. The cross section of this drawing is made along section line B-B as shown in Fig. 1 and the direction of view is indicated there as well. Anchoring apparatus 1 is shown in this drawing in its full engagement state, where connecting element 3 is fully inserted into anchoring element 2 and locked to it. After connecting element 3 has passed through opening 21, pins 35 are free to extend back outwardly and lean over rim 23, thereby preventing disconnection of connecting element 3 from anchoring element 2, and making anchoring hole 26 firmly connected to connecting hole 36, to provide anchored hanging or attaching device.

[0046] Reference is made now to Figs. 9A-9C, which schematically depict three consecutive steps of anchoring connecting element 3 to an anchoring element 3, according to embodiments of the present invention. Reference is made now also to Fig. 10, which is a schematic flow diagram of a method for anchoring a heavy and / or large object, a ladder in this example, to a high anchoring point, according to embodiments of the present invention. In order to enable easy, safe and simple attaching of heavy and / or large object to a high anchoring point an anchoring apparatus, such as apparatus 1 , is provided (step 1002). A pulling rope is threaded through rope connecting holes 331 and 332 in connecting element 3 and is firmly secured there, as described in details below and the other end of the pulling rope is threaded through rope threading hole 25, leaving its free end loose for pulling, for example, by hand at later stage (step 1004). Anchoring element 2 is lifted up and is secured to an anchoring location, while making sure that the rope is maintained threaded through hole 25 and connecting element is left connected but no load is exerted on the pulling rope (step 1006, Fig. 9A). At this stage a load that needs to be pulled up and secured, such as a long ladder, is attached to connecting element 3 at its hanging hole 36 (step 1008). After the load has been attached to connecting element 3 the pulling rope may be pulled by a user, which may be located at any desired, or convenient location as long as the free end of the pulling rope is at reach there. The pulled rope is pulled through threading hole 25 in anchoring element 2 thereby pulling connecting element 2, and the load connected to it, towards anchoring element 3 (step 1010, Fig. 9B). The rope is kept being pulled by the user until connecting element 2 reaches the bottom entry 21 of anchoring element 2, inserted into it and is locked inside anchoring element 2 (step 10, Fig. 9C and Figs. 7A-7C). at the end of the operation connecting element 3 is locked inside anchoring element 2 and thereby anchored to the anchoring location of anchoring element 2 and this way provides safe and secured support to the load, such as a long ladder. At this stage the pulling rope may be released from anchoring device 1 and be used for other needs, without effecting the support anchoring device provides to the load.

[0047] Reference is made now to Figs. 9D-9F, which are schematic illustrations depicting three consecutive steps of attaching a rope to connecting element 3, according to embodiments of the present invention. Prior to beginning pulling connecting element 3 towards anchoring element 2, as described above, a pulling rope may be firmly attached to connecting element 2 as follows. Pulling rope may be inserted through hole 331 at the vertex of conical portion 31 and further through hole 332, as depicted by the arrow in Fig. 9D until its edge protrudes out of hole 332 as depicted in Fig. 9E. At this stage a knot may be made at the edge of the rope so as to prevent pulling it out of hole 332 when pulling force is exerted on the rope as depicted in Fig. 9F. preferably the knot, or any other blocking means that is used, should not protrude out of the outer face of conical portion 31 when that edge of the rope as come to final position after being pulled in, in order to not present obstacle to smooth entrance of connecting element 3 into anchoring element 2, as described in details above.
