DETAILED DESCRIPTION OF EMBODIMENTS

FIG. 1 is a bar clamping member 100 of a universal support clip, in accordance with some embodiments. The bar clamping member 100 is constructed and arranged to couple to a handlebar or other tubular structure, for example, shown in FIG. 5. As shown, the bar clamping member 100 in some embodiments is removably attached to a shopping cart, but not limited thereto. For example, the bar clamping member 100 may be positioned about the handlebar of a bicycle.

The bar clamping member 100 comprises a body portion 117 having a curved interior wall 121 forming an opening 118, two outer ends 112, 114, each extending from one end 110 of the body portion 117 and separated by a gap 115, and a base portion 122 extending from the other end 120 of the body portion 117. The first end 10 can be in an open state where the gap 115 is widened to receive a handlebar or other tubular object, or a closed state where the handlebar or tubular object is secured by the body portion 117.

At the first end 110 of the body portion 117, the two outer ends 112, 114 each has a hole 116. The holes 116 are aligned with each other, i.e., extending along the same axis, so that the holes 116 can each receive a bolt 130, or screw or other elongated coupling device, which can be inserted into the holes 116. One of the outer ends, for example, 112, may have a threaded hole 116 for receiving a threaded distal end of the coupling device 130, which when threaded can result in a force applied to the outer ends 112, 114 so that they in turn move toward each other, therefore tightening or compressing the curved interior walls 121 of the bar clamping member 100 forming the opening 118 positioned about a handle or other tubular object inserted in the opening 118 of the bar clamping member 100 formed by the interior walls 121. The hole 116 of at least one outer end, for example outer end 114, may include a recess 125 or the like having a width that receives the head of the bolt 130. Although a threaded coupling device 130 is shown and described, other coupling devices may equally apply to apply a force for example to squeeze the outer ends 112, 114 together.

In some embodiments, as shown in FIG. 7B, the bolt 130 may extend through both outer ends 112, 114 so that a distal end of the bolt 130 is exposed. A nut 131 may be threaded about the exposed distal end of bolt 130 to press the outer ends 112, 114 together, resulting a force applied by the bar clamping member 100 about the handlebar 22. Although threaded coupling devices 130, 131 are shown and described, other coupling devices may equally apply to squeeze the outer ends 112, 114 together. A feature of the bar clamping member 100 is the need for a single coupling device 130, e.g., a single threaded screw, bolt, or the like for locking the bar clamping member 100 against a handle or the like. The feature of a single coupling device extending through a distal end of the bar clamping member 100 offers simplicity and ease-of-use during assembly, when coupling the bar clamping member 100 to the handlebar 22. When tightened sufficiently, the bar clamping member 100 does not rotate about the handlebar 22 and remains stationary, and therefore offers safety and longevity, when fastening different phone holders or other electronic device components to the shopping cart.

The curved interior wall 121 forming the opening 118 may have a circular, elliptical, or related shape for tightly positioning about the handle or other tubular object. In some embodiments, a plurality of protrusions 119, bumps, or the like extend from the interior wall 121 to directly contact the handle and to apply additional force and reducing the risk of undesirable rotation of the bar clamping member 100 about the handle during operation. The protrusions 119 may have compressible and/or elastic qualities so that the protrusions 119 change shape or form when pressed against the handle, and returns to an original state when no force is applied. Alternatively, or in addition, a coating or layer of a material providing friction may be bonded to, sprayed on, or otherwise adhered to the interior wall 121. This, and/or other techniques not mentioned but equally applicable, may be used to further reduce the risk of undesirable rotation of the bar clamping member 100 about the handle during operation.

In order for a handle or other tubular object to be inserted into the bar clamping member 100 so that the wall 121 can surround it, the handle or the like is inserted through the gap 115 between the outer ends 112, 114 which extends to the hole 116. The gap 115 has a predetermined width for example, about 0.16 inches, when no force is applied, for example, when the bolt 130 is not inserted. When the width of the gap 115 is reduced, i.e., less than 0.16 inches, due to the force applied by the bolt 130 and threaded unit 131, the width, circumference, or other dimension of the opening formed by the interior wall 118 is reduced by the corresponding reduction of width of the gap 115.

The base portion 122 and body portion 117 may be unitary and machined or molded from a same material. In other examples, the base portion 122 and body portion 117 are formed separately and coupled together, for example, using adhesives, coupling mechanisms such as screws, rivets, or the like. The cylindrical configuration may have a predetermined outer width such as 0.5 inch outer diameter but not limited thereto. The base portion 122 is constructed and arranged to receive a removable, replaceable, and interchangeable device mount interface 200A (FIGS. 1 and 2) or 200B (FIGS. 1 and 3), and hold it in place against the bar clamping member 100. Thus, the clamping member 100 universally accepts any smart device holder, for example, shown in FIG. 5, due to the ability to change between different device mount interfaces, for example, replace interface 200A with interface 200B. The base portion 122 is preferably unitary with the body portion 117, i.e., formed of a same material, so that the body portion 117 and outer ends 112, 114 extend from the unitary base portion 122. The material forming the outer ends 112, 114 provide some amount of elasticity or related characteristic to allow the gap 115 to expand and contract relative to the unitary base portion 122 when the coupling device 130 is used to squeeze the ends 112, 114 together. The device mount interface 200A, B (generally, 200) may include an adapter 201, for example, a threaded element, that is inserted into an opening 124 in the base portion 122. In other embodiments (not shown), the device mount interface 200 may include an opening that mates with a male adapter 201 extending from the base portion 122. The opening 124 may be threaded, for example, constructed and arranged to receive any male adapter so long as the adapter 201 has a dimension and configuration for mating with the threaded opening. In some embodiments, the threaded adapter 201 extends from the base portion 122 and the threaded opening 124 is in the interchangeable device mount interface 200.

The adapter 201 may be formed of a rigid material, such as metal, while the base portion 122 is formed of plastic or other different material. Here, the adapter 201 provides rigidity and support to prevent or reduce the risk of breaking the bar clamping member 100 during operation, for example, when a force is exerted on the device mount interface 200 by an attached device during operation when the bar clamping member 100 is coupled to a handlebar 22, for example, shown in FIG. 5, for example, using a coupling element 130 described in FIGS. 1-3.

As previously described, the universal support clip 10 may include a removable, replaceable, and interchangeable device mount interface 200 for coupling to the bar clamping member 100. The universal support clip 10 in operation coupled is between a shopping cart and a mobile electronic device, in accordance with some embodiments, for example, shown in FIG. 5

The device mount interface 200 may have different configurations. For example, as shown in FIGS. 1 and 2, the device mount interface 200A may include a proximal base 202, a mid-portion 204, and a distal end 206. The abovementioned universal adapter 201 may extend from the base 202 for interfacing with the threaded opening 124 of the bar clamping member, or the base 202 may have a threaded hole or the like for coupling with a male element extending from the bar clamping member 100. Thus, the universal adapter 201 may extend from other of the bar clamping member 100 or the device mount interface 200A, and be threaded into the other of the bar clamping member 100 or the device mount interface 200A. A feature of the universal support clip 10 is that the universal adapter 201 provides additional rigidity, reinforcement, and strength to the support clip 10 because the universal adapter 201 is formed of metal or other material more rigid than the bar clamping member 100 and/or interface 200, and reinforces the polymer material forming the bar clamping member 100 and device mount interface 200. Other materials may equally apply, such as nylon and so on. Thus, the risk of damage or breaking of the clip 10 is reduced by the presence of the universal adapter 201, since the interior include metal elements, i.e., universal adapter 201 and/or coupling element 130 extending through damage-prone plastic elements of the clip 10.

The mid-portion 204 of the device mount interface 200A may include a gap 205 and sub-portions on either side of the gap 205, each including a hole extending therethrough for receiving a threaded bolt 207 or other elongated coupling device, similar to the bolt 130 coupled to the bar clamping member 100. The distal end 206 may have two side portions 206 that form an opening 208, which can be coupled to a mobile electronic device, such as a personal smartphone, a store-provided scanning device, and so on, for example, a holder of the mobile electronic device, for example, a bulbous male coupling 33 of a phone holder base 32 shown in FIG. 5. The opening 208 can be closed about the phone holder coupling 33, for example, a round distal end, when the gap 205 is reduced by a force caused by the coupling device 207, in a similar manner as the gap 115 and bolt 130 described with respect to the bar clamping member 100. One or two second openings 209 may also be formed between the two side portions 206, which are circular, elliptical, or otherwise curved in shape, for example, shown in FIGS. 1 and 2. The second openings 209 may be perpendicular to the central opening 208 which is at an outermost end of the distal end 206 of the device mount interface 200A. The force applied by the distal end 206 on a male round or bulbous phone holder element or the like can be controlled by the torque or force applied by the bolt 207 or other elongated coupling device inserted into the hole in the mid-portion 204 for closing or opening the gap 205.

In another example, as shown in FIGS. 1 and 3, the device mount interface 200B may include a proximal base 212 and a round distal end 214. The abovementioned universal adapter 201 may extend from the base 212 for interfacing with the threaded opening 124 of the bar clamping member, or the base 212 may have a threaded hole or the like for coupling with a male element extending from the bar clamping member 100. Thus, the universal adapter 201 may extend from other of the bar clamping member 100 or the device mount interface 200B, and be threaded into the other of the bar clamping member 100 or the device mount interface 200B.

The distal end 214 includes a male bulbous or round portion that extends from the proximal base 212, and is constructed and arranged to mate with a female connector of a mobile electronic device, such as a personal smartphone, a store-provided scanning device, and so on, or more specifically, a holder of the mobile electronic device, for example, a holder of the mobile electronic device, for example, a female coupling (not shown) of a phone holder base 32 shown in FIG. 7. In this example, the mobile device holder can swivel or otherwise rotate about the round proximal base 212 which remains stationary due to its coupling arrangement with the bar clamping member 100 as shown in FIG. 3.

FIG. 4 a perspective view of a charging device 300, in accordance with some embodiments. In some embodiments, the charging device 300 includes a USB connector 302, a mounting interface 304, and a wire insert 306 (not shown but identified in FIG. 4). Also not shown is the interior of the charging device 300, which includes pin-to-pin conversion elements for exchanging power, data, and/or other signals between a conductive wire extending from a battery or other power source and received at the wire insert 306 and an electronic device, such as a USB cable of an electronic device, electrically and removably coupled to the USB connector 302. The wire insert 306 may be a male or female connector for electronically mating with a connector of the conductive wire received from the battery or other charging source, or the wire insert 306 may include exposed conduits for directly coupling with individual wires of the received conductive wire.

The electronic device may be a smartphone, scanning device, or other mobile device positioned in a phone holder 30, for example, shown in FIG. 5, or a separate mobile device, for example, held in the hand of a user who operates the device by inserting a USB cable extending from the mobile device into the USB connector 302. In this example, another mobile device may be positioned in the phone holder 30, but receives a source of power via a different USB port, for example, a charging port 38 located on the phone holder itself 30, whereby two electronic devices can independently and simultaneously be charged. Thus, a user has the option of using the charging device 300 to charge a personal mobile device, a store-provided mobile device, or both.

Referring again to FIG. 5, a device mount interface 200 shown in FIGS. 1-3 is used to attach between a universal support clip 10 and a phone holder 30 or the like, which includes a base 32 and male or female coupling 33 that interfaces with the device mount interface 200.

FIG. 6 is a cutaway view of the phone holder 30 of FIG. 5, in accordance with some embodiments. The phone holder 30 comprises a base 32, a coupling 33, first and second tension legs 34, first and second phone support legs 35, first and second grooves 37 in the base 32 where the tension legs 34 can move, a charging port 38 coupled to the charger 300 shown in FIG. 4, and a high tension spring 39A and low tension spring 39B in the base 32 coupled between the two tension legs 34, for providing a force against a phone or related mobile device inserted between the tension legs 34. A conductive cable, wire, or the like, may extend directly from the phone holder 300 to a battery or other charging source. Referring again to FIG. 5, a wire 36 may connect to a battery backup or the like that in turn is connected to a charging station located at one of the shopping cart wheels for providing a source of alternative power produced by a shopper moving the cart. Thus, in some embodiments, a battery may be connected to a charging device that receives power from energy produced by motion of the shopping cart wheels, or from another alternative source, such as solar or wind energy device, which in turn charges the battery. The battery in turn can be used to provide power directly to the phone holder 30 which in turn includes a port that interfaces with a mobile device positioned in the phone holder 30 and/or provide power to the charging device 300 described with reference to FIG. 4.

FIG. 7A is a view of a universal support clip 10, in accordance with other embodiments. FIG. 7B is a front view of the bar clamping member 400 and swivel device mount interface 200C of FIG. 7A separate from each other.

The bar clamping member 400 comprises a body portion 117 and base portion 122 similar to or the same as those of the bar clamping member 100 of FIGS. 1-3, and details are therefore not repeated due to brevity. A key difference between the bar clamping member 400 of FIGS. 7A and 8B and the bar clamping member 100 of FIGS. 1-3 is that the bar clamping member 400 includes a lock nut 402 and swivel element 404 at the end 120 opposite the end 110 having the outer ends 112, 114, instead of a base portion 122 with a universal opening 124. The lock nut 402 when rotated about the body portion 117 can adjust the amount of tension or other force on the swivel element 404. The swivel element 404 is constructed and arranged to receive a bulbous end of an interchangeable device mount interface 200C. The device mount interface 200C as shown may have a round or bulbous first and second end. In other embodiments, one end is bulbous for positioning in the swivel element 404, and the other end may have a different shape, size, or configuration, for example, configured to receive device mount interface 200A shown in FIG. 1.

During operation, as shown in FIG. 7A, the universal support clip 10 has two swivel locations, each allowing multiple degrees of freedom. The first swivel location as at swivel element 404. The second swivel location as at the other end of the device mount interface 200C mating with the phone holder 30 of FIG. 5.
