DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
(13) To aid understanding, this document is organized as follows. First, operation of an exemplary multi-cart control system is introduced, with reference to
(14)
(15) In some embodiments, the ratcheting member 125 has a free-rotating mode, and a ratcheting mode. When in the free-rotating mode, the securing rope 120 can move through the ratcheting member 125 in either direction. For example, when in the free-rotating mode, if one lengthens the free portion 135 of the securing rope 120, the tightening portion 140 will be commensurately reduced. And, when in the free-rotating mode, if one lengthens the tightening portion 140, the free portion 135 will be commensurately reduced. But when in the ratcheting mode, the ratcheting member 125 will permit the securing rope 120 to be moved therethrough in only one direction. For example, when in the ratcheting mode, if one pulls on the free portion 135, the tightening portion 140 will be commensurately reduced. But, when in the ratcheting mode, if one pulls on the tightening portion 140, the ratcheting member will not permit the tightening portion 140 to lengthen, and thus no reduction of the free portion 135 will result. Such a ratcheting mode may advantageously facilitate the secure maintenance of the nested train 100 of shopping carts in the bowed configuration shown in

(20) In
(21) Various exemplary cart-engagement hooks 420 may include various types of cushioning material. For example, in some embodiments, the cushion material may be of EPDM rubber, for example. EPDM rubber may advantageously provide UV resistance. Various cushioning materials may be chose to provide a soft cart-interfacing surface. Some cushioning materials may be pliable so as not to damage a shopping-cart handle. Some shopping-cart handles may include plastic components that may be broken if damaged (e.g., marred, dented, deformed, broken, etc.) without a cushioned hook. Various shopping carts may have various types of handle construction (e.g., plastic, tubular steel, plastic covering over steel, etc.). Some stores, for example, may print a company logo on a plastic covering. Such a company may desire that the company logo remain visible after cart use, for example. A cushioned cart-engagement hook may advantageously prevent damage to shopping cart handles.
(22)
(23)
(24) In some embodiments, a shopping-cart connecting member may include a secure hook with a protective cover. The secure hook may have a safety latch. In some embodiments, the safety latch may have an open position and a closed position. In an exemplary embodiment, a spring bias may provide a force impulse to the safety latch biasing the safety latch to the closed position. When the secure hook is affixed to a shopping-cart handle, the safety latch may advantageously prevent accidental disengagement of the shopping-cart handle. This in turn may prevent collisions between renegade shopping carts and other vehicles or persons.
(25) Various embodiments of secure handle coupling devices have been disclosed in U.S. Provisional Application 62/129,100, entitled Multi-Cart Control System, filed by Justin Grimes on Mar. 6, 2015. The entirety of the foregoing applications are hereby incorporated by reference. In
(26) Various means for securing a shopping cart handle may include, for example, a hook having a spring biased .[.gait.]. .Iadd.gate.Iaddend.. In some embodiments a hook may have a gate requiring two user actions for opening, for example. In an exemplary embodiment, a handle may be securely coupled using a braid in combination with a secure capture mechanism. In some embodiments a secure capture mechanism may have a normally closed mode and a manually openable mode, for example.
(27)
(28)
(29)
(30) The crimp devices are located proximate each of the two ends. The locations of the crimp devices with respect to each of the two ends determines the size of the loops 770, 785. The crimp device 785 has a length that permits both crimping of two transversely adjacent sections of rope, but also two longitudinal sections of rope. For example, cart-connecting member may be manufactured by cutting a rope to a predetermined length. The rope may then be looped so that each of two ends of the rope are longitudinally aligned and butted together. The loop of rope may be drawn together in a lateral fashion so that a double rope results. The longitudinally aligned butted section may be centered within an uncrimped connecting device. The connecting device may then be crimped so as to secure both the adjacent longitudinal sections as well as the adjacent lateral sections of rope. Another crimping device may then laterally connect the ropes proximate another end of the loop of rope.
(31) The double rope may have some advantageous properties with regard to coupling to a shopping cart. The double loop of rope may resists sliding transversely along a shopping-cart handle. In response to a transverse force, each transversely adjacent segment of the double rope may start to rotate about a central axis of each transversely-adjacent segment of the double rope. Such rotation may then be inhibited by interference with the adjacent section of rope. Such rotation may be inhibited by the rotationally secure crimping device coupling the two sections of double rope. Such rotation may be inhibited by a round cross section minimizing a handle engagement area. Such rotation may be inhibited by a round cross-sectional profile finding a detent feature of a shopping-cart handle and being retained in such feature. Because the double rope may provide secure engagement with a shopping-cart handle, the double rope may provide a low abrasion interface with a shopping-cart handle.
(32)
(33)
(34) In some embodiments, a secure carabiner may provide a coupling aperture to both one end of a shopping-cart coupling member and a quick-link connector. The shopping-cart coupling member may be secured to the secure carabiner via an eyelet at one end of the shopping-cart coupling member. The quick-link connector may have a closed figure aperture for secure connection to the secure carabiner. Various types of devices may be used to secure a shopping-cart coupling member to either a rope or a ratcheting device. In some instances, a carabiner may be used for such secure connection. In some embodiments, the carabiner may be opened by unscrewing a threaded .[.gait.]. .Iadd.gate .Iaddend.member, for example. In some embodiments a two-action gate member may be used to open and close a coupling member. The secure carabiner may advantageously permit attachments that are semi-permanent. Such attachments can be removed using a two-action .[.gait.]. .Iadd.gate .Iaddend.and/or using tools, for example. But such attachments may be inhibited against accidental removal by the two-action .[.gait.]. .Iadd.gate .Iaddend.or the need for tools.
(35) Although various embodiments have been described with reference to the Figures, other embodiments are possible. For example, a first connecting end may be looped around a first handle of a front shopping cart and a second connecting end may be looped around a second handle of a rear shopping cart, while a plurality of additional shopping carts are loosely nested between the front and rear shopping carts. The tension assembly may then be operated by pulling on the handgrip to increase a tautness of the elongated member extending between the first and second connecting ends. The tension mechanism may operate in a ratchet-type manner to automatically secure the elongated member in the taut position upline of the tension mechanism. In an exemplary embodiment, the elongated member is tightened until at least a front set of wheels of the front cart and a rear set of wheels of the rear car are raised above a ground surface, thus lessening a resistance of the shopping carts on the ground surface. When the shopping carts are moved to a destination, a release may be operated on the tension mechanism to loosen the taut elongated member such that the connecting ends may be removed from the corresponding shopping-cart handles.
(36) In accordance with an exemplary embodiment, the first and/or second connecting ends may include an adjustable strap for loosening or tightening the strap around the corresponding shopping-cart handle. In some embodiments, the strap may be a rope-type. In some embodiments, the strap may be flexible. A flexible strap may present a coupling interface to a shopping-cart handle that has a large surface area. A large engagement surface may present a low abrasive interface to the shopping-cart handle. In other embodiments the strap may be rigid, such as a plastic for example. A rigid strap may be used to connect to a dedicated connection point on a shopping cart, for example. The dedicated connection point may be adapted to engage the rigid strap, for example. Such connecting members may provide secure connection and may minimize the time for connecting and disconnecting the strap to a shopping cart. In some embodiments, a ratchet-type device may be employed on each connecting end for securing the connecting end in a looped-configuration around a portion of the shopping cart, such as the shopping-cart handle for example.
(37) In various embodiments, apparatus and methods may involve a receiver built-in or integrated into the shopping cart. In some embodiments, an aftermarket receiver may be affixed to the shopping cart for attaching the respective connecting end. In some embodiments, the receiver may be a hook-shape. In various embodiments, the receiver may be a slot or opening formed within an integral or attached support. A person of skill in the art will recognize that complementary connecting devices can be transposed between a shopping cart and a shopping cart securing system. In some embodiments, the connecting end or portion of the tension assembly may be integrated or semi-permanently secured to the shopping cart. For example, the shopping-cart handle may include a wound elongated member, such that elongated member may be released and retracted in a winch or ratchet-type manner. In some embodiments, an actuating device, such as for example a spring, may assist in retracting the elongated member.
(38) In an exemplary embodiment, the tension mechanism may be a ratchet-type device, such that may permit one-way operation or tightening, yet permit loosening through the use of a release. In some embodiments, the release may be lever or a push-button type. In some exemplary embodiments, the tension mechanism may be a manually powered winch or spooling device. In other embodiments, the tension mechanism may be motor-driven winch. For example, the winch may include an electric motor. In some embodiments, the tension mechanism may include a locking member for locking the elongated member in a given position with respect to the tension mechanism, such as for example in a taut position. In some embodiments, the tension mechanism may be a pulley-type. For example, the elongated member may be wound around the pulley and secured upon a forward shopping-cart handle to maintain the elongated member in a taut position upline. In accordance with another embodiment, tension mechanism may include a tension gauge for assisting an operator in maintaining a safe operating tension between connecting ends.
(39) In accordance with another embodiment, an anti-theft device may be incorporated to prevent removal of the connecting ends from the corresponding shopping carts. For example, the connecting ends may include combination or keyed lock which restricts the connecting ends from being removed from the end shopping carts and thus prevents removal of the shopping carts between the end carts because the shopping carts are in the nested position.
(40) In an illustrative embodiment, a cinch for securing a train of nested shopping carts may include a rope comprising a substantially-zero-stretch core. The rope may have a handle coupled to a first end and a shopping-cart attachment member coupled to a second end. In some embodiments, the cinch may include a tightening member having a securing member, a ratcheting pulley and a locking member. The rope may be looped about a semi-annular portion of the ratcheting pulley separating the rope into a tightening portion and a free portion. In some embodiments, the tightening portion may be between the shopping-cart attachment member and a pulley-contacting portion. The free portion may be between the handle and the pulley-contacting portion.
(41) In various embodiments, when the locking member is in a locked mode, the ratcheting pulley may be prevented from rotating in a first direction of rotation. A user may be able to pull on the handle to lengthen the free portion of the rope which may rotate the ratcheting pulley in a second direction of rotation and simultaneously reduces the tightening portion of the rope. In some embodiments, when the locking member is in an unlocked mode, the ratcheting pulley may freely rotate in either of the first or the second directions in response to forces imparted to the ratcheting pulley from the rope.
(42) In some embodiments the cinch may include a flat securing strap having a length greater than a circumference of a shopping-cart handle so as to permit the flat securing strap to be looped around the shopping-cart handle and secured to the tightening member via the securing member.
(43) In an illustrative embodiment, various means for distributing a force along a portion of a shopping-cart handle may be employed. For example, in some embodiments, the force may be distributed along an axial length of the shopping-cart handle. A flat strap having a width may distribute the force along the width. The distribution of force along the width may be substantially uniform along the width. In some embodiments, the force may be distributed radially about the handle. For example a loop of material may circumscribe all or a portion of the handle. The force may be radially distributed along an annular portion of the handle. The radial distribution may result in a lower force at a specific annular position than if the strap were connected only at that annular position, for example.
(44) A number of implementations have been described. Nevertheless, it will be understood that various modification may be made. For example, advantageous results may be achieved if the steps of the disclosed techniques were performed in a different sequence, or if components of the disclosed systems were combined in a different manner, or if the components were supplemented with other components. Accordingly, other implementations are contemplated.
