In some cases, customers bring their own portable computing device, e.g., a smartphone, computing tablet, or the like, into a retail store for use while shopping. In other cases, portable computing devices, or mobile devices, are distributed by the retail store for customers to use while in the store. For example, portable scanning devices are loaned to customers in some stores so that the customers can scan and electronically pay for their purchases while they shop.
As discussed herein, embodiments of the present inventive concepts relate to holders for portable computing devices, and more specifically to a self-locking clip mechanism that secures a portable computing device cradle to a shopping cart. A portable computing device such as a personal smartphone or store-provided scanning device may in turn be removably coupled to the cradle. Mobile devices can be any type of portable computing device such as, but not limited to, portable scanners, smart phones, computing tablets or pads, portable computers, global positioning system devices, portable digital assistants, or any other type of portable computing device, and can perform a number of computing functions related to a shopping application such as point of sale (POS) functions.
Along these lines, each shopper usually carries at least one mobile device. The mobile devices are often an integral part of the shopping experience, being used to find items in a store, scan items to be purchased and electronically complete the purchase. But it is difficult to both push the shopping cart and control the mobile device. In addition, it is desirable to have the mobile device be positioned close to the shopper as the shopper shops.
Described herein is a self-locking clip mechanism that includes an outer clip component, also referred to as an outer sleeve, which removably interlocks with an inner clip component, also referred to as an inner sleeve, to collectively form a circular, oval, or other relevant shaped interior that surrounds a cross-sectional region of a shopping cart handle or other tubular element and applies a force against the shopping cart element so as to not move, e.g., rotate about the shopping cart handle. One of the clip components has an interlock slide or the like that is configured to mate and lock with a cradle of a portable computing device. Thus, the cradle can be firmly attached to the shopping cart by the self-locking mechanism so that portable computing devices can be repeatably inserted into the cradle for use by a customer in a hands-free manner, for example, allowing the customer to push the shopping cart while also viewing a display on the computing device attached to the cradle on the shopping cart.
Also described herein are embodiments of the self-locking clip mechanism which in some applications may be part of a mobile device holder that holds a mobile device, and couples the mobile device to a handle of a shopping cart or shopping basket. When the mobile device holder is coupled to the shopping cart handle, it holds and positions a mobile device so it is close and convenient for us to the customer. The mobile device holder also includes a charger to charge the mobile device while it is held by the mobile device holder. The mobile device holder can be electrically coupled to both the shopping cart and the mobile device. Power can be supplied to the mobile device holder, and the mobile device, from the shopping cart or another power supply. A scanner for scanning bar codes can be coupled to the mobile device holder to provide bar code inputs to the mobile device. The mobile device holder can include a ‘help’ button that the customer can use to summon help from the retail store if needed. The mobile device holder provides a convenient dock for mobile devices of all types, keeps the devices charged, and provides a convenient means for holding a mobile device for use during the shopping trip.
FIG. 1 is a perspective view of a self-locking clip mechanism 10, in accordance with some embodiments. In preferred embodiments, the self-locking clip mechanism 10 is constructed and arranged to secure a mobile phone cradle to a shopping cart.
The self-locking clip mechanism 10 includes an inner clip component 24, also referred to in some embodiments as a first sleeve, and an outer clip component 22, also referred to in some embodiments as a second sleeve, that are constructed and arranged to removably interlock with each other.
Each of the clip components 22, 24 are incomplete annular cylinders, as best seen in FIGS. 1-4. An inner surface of the outer clip component 22 and an inner clip component 24 each has an arc or curve shape, e.g., a circular, oval, C-shape, semi-circle, or horseshoe shaped interior, for securing about a tubular structure, such as a handlebar or other tubular element of a shopping cart or the like (e.g., shown in FIG. 5). In particular, the inner surface has a curvature dimensioned to match an outer curvature of the handlebar or other tubular element. The coupling formed by the outer clip component 22 and an inner clip component 24, when secured about the handlebar, operates to induce a radially inward force on the inner surface of the self-locking clip mechanism 10. In some embodiments, interiors of the outer clip component 22 and an inner clip component 24 can be curved for positioning about a handlebar or other tubular structure, and the exteriors of the outer clip component 22 and an inner clip component 24 can be of a different shape, for example, linear or curved.
Each of the outer clip component 22 and an inner clip component 24 may be formed of metal, plastic, or other rigid continuous one-piece material having the strength, durability, and other characteristics sufficient for securing a portable computing device to the tubular structure via a mobile device cradle that is coupled to one of the outer clip component 22 and an inner clip component 24. For example, the outer clip component 22 and an inner clip component 24 may be formed of plastic or other material that provides rigidity and some elasticity so that the ends of the inner clip component 24 can expand to widen an opening 34 to fit around a tubular object such as a shopping cart handlebar, and for the outer clip component 22 to expand to widen an opening 33 to fit around the inner clip component 24. Inner clip opening 34 extends a length of inner clip 24. Similarly, outer clip opening 33 extends along a length of outer clip 22.
In embodiments, the inner clip component 24 includes a base protrusion 32 at an opposite side of the inner clip component 24 as the opening 34. The base protrusion 32 is constructed and arranged to have a wider or thicker region then the ends of the clip and to extend through the opening 33 in the outer clip component 22 so that the ends of the outer clip component 22, i.e., ends on either side of the outer clip opening 33, do not interfere with an interlock slide 25 or otherwise prohibit the mobile device cradle from being coupled to the interlock slide 25. In some embodiments, the interlock slide 25 has a dovetail configuration, referred to as a dovetail tongue or the like.
The outer clip component 22 and inner clip component 24 may be interlocked with each other to form a 360 degree circumference from their combined interiors positioned about the tubular handlebar or the like. In some embodiments, at least a portion of the inner clip component 24, for example, end portions, are positioned inside the outer clip component 22. During operation, the inner clip component 24 is clipped to a handlebar 118 (see FIG. 6) so that the interior region of the inner clip component 24 directly abuts and at least partially encircles the handlebar 118. Although a handlebar 118 is shown, the mobile device holder 110A can be coupled to any rod-shaped handle or rail, such as the handle of a flatbed-type cart or a rail, for example, but not by way of limitation.
The outer surface of the inner clip component 24 directly abuts an inner surface of the outer clip component 22, and may abut or otherwise apply a force to a remaining portion of the handlebar 118 not otherwise surrounded by the inner clip component 24. At least a portion of the interior of the inner clip component 24 may include a padding or foam liner or the like to provide an improved grip about the shopping cart handlebar 118.
The outer clip component 22 and inner clip component 24 may join together securely by at least one locking slot 23, or hole, window, groove or the like, in the outer clip component 22 that is constructed and arranged to mate with a locking protrusion 26 extending from a surface of the inner clip component 24. The width, diameter, circumference, shape, or other feature of the locking slot 23 can vary, depending on the width, diameter, circumference, shape, or other feature of the locking protrusion 26. In doing so, the outer clip component 22 and inner clip component 24 apply a force directly on the handlebar. Preferably, the outer clip component 22 has two locking slots 23 arranged 180 degrees from each other. Each locking slot 23 is dimensioned to receive one of two protrusions 26 extending from the inner clip component. The two protrusions 26 may also extend 180 degrees from each other to align with and be received by a corresponding locking slot 23. In some embodiments, the outer clip component 22 has the protrusions 26 that extend from the interior of the outer clip component 22 (distinguished from protrusions 26 extending from the exterior of the inner clip component 24 as described in abovementioned embodiments) to mate with locking slots 23 in the inner clip component 24. In some embodiments, a back region of the clip 10 may include one or more support brackets, for example, a groove or the like at the back of the clip that functions as a bracket for supporting the holder and the clip together.
A top region of the inner clip component 24 includes an interlock slide 25 that is constructed and arranged to mate with a bottom of a mobile device cradle 50, for example, shown in FIGS. 4 and 5 to collectively form a mobile device holder 110. In some embodiments, the interlock slide 25 extends from the outer surface of the inner clip component 24 along a longitudinal direction of the inner clip component 24, as shown. In some embodiments, the interlock slide 25 has a taper, or more specifically, each tapered size of the projection of the interlock slide 25 tapers from an outermost surface of the slide 25 to a region where the slide 25 extends from the outer surface of the inner clip component 24. Mating surfaces of the tapered interlock slide 25 and a groove 57 of the mobile device cradle 50 are joined together to form a coupling interface. In some embodiments, the interlock slide 25 has a hole for receiving a screw or the like extending through the cradle to further hold the cradle in place against the self-locking clip mechanism 10. In some embodiments, the inner clip component 24 has a groove at its top surface and the cradle 50 has the protrusion for mating with the groove in the inner clip component 24.
Referring to FIGS. 4 and 5, the mobile device cradle 50 may include but not be limited to a top plate 51, first sidewall 52, second sidewall 53, a bottom plate 54, a cradle connector 55, and a coupling element 56.
When assembled as shown in FIG. 4, the top plate 51, first sidewall 52, second sidewall 53, a bottom plate 54, cradle connector 55, and coupling element 56 form the cradle 50 in which a portable computing device can be inserted and secured against a shopping cart handlebar 118 or related tubular structure. A bottom surface of the bottom plate 54 includes at least one groove 57 or the like for coupling with the interlock slide 25 of the self-locking clip mechanism 10. A top surface of the bottom plate 54 may include a plurality of grooves 61 or the like for coupling with protrusions 62 or the like extending from the top plate 51 to secure the top plate 51 to the bottom plate 54.
The cradle connector 55 is positioned in the middle of the cradle 50, and supports the coupling element 56 in place. The cradle connector 55 functions as a separator and locking bracket. The coupling element 56 may be a pin formed of the same material as the bracket 55. The coupling element 56 may be a pin, screw, bolt, or other attachment mechanism for securely coupling the bottom plate 54 of the cradle 50 to the self-locking clip mechanism 10. The pin 56 may hold a top section of the locking clip in place. Coupling element 56 may extend from the bottom plate 54 of the holder to a section of the locking clip, for example, hole 31 in the top section of the locking clip. For example, the coupling element 56 can be inserted in a hole 63 in the cradle bottom plate 54 that is aligned with a hole 31 in the interlock slide 25 of the self-locking mechanism 10 when the interlock slide 25 is inserted in the bottom plate groove 57. The coupling element 56 may provide a reinforcement in ensuring that the self-locking mechanism 10 is securely coupled to the mobile device cradle 50.
A feature of the self-locking clip mechanism 10 is that multiple screws or other permanent fastening components are not required to secure the clip mechanism 10 to a shopping cart handlebar 118. Referring again to FIGS. 4 and 5, the inner clip component 24 is securely coupled to the mobile device cradle 50 due to the coupling element 56. Thus, the outer clip component 22 may be separated from the inner clip component 24 by opening the outer clip component 22 to remove the outer clip opening 23 from the inner clip protrusion 26, or vice versa. Here, the cradle 50 and inner clip component 24 may be removed together from the handlebar 118.
FIG. 7 is a flowchart of a method 100 for coupling a mobile computing device 114 to a shopping cart handle 118, in accordance with some embodiments. In describing the method 100, reference is made to elements of FIGS. 1-6.
At block 102, a self-locking clip mechanism 10 is assembled about a shopping cart handlebar or other tubular structure. In particular, the two halves of the self-locking clip mechanism 10, or more specifically, outer clip component 22 and inner clip component 24, are coupled to each other about the handlebar 118 or the like, for example, shown in FIG. 6. In doing so, the interlock slide 25 is positioned at a top region of the self-locking clip mechanism 10 above the handlebar 118 so that a line-of-sight is formed between the interlock slide 25 and a shopping cart user.
At block 104, the mobile device cradle 50 is assembled, for example, shown in FIGS. 4 and 5. In some embodiments, the mobile device cradle 50 is molded or machined from a single stock, and therefore, little or no assembly is required.
At block 106, the self-locking clip mechanism 10 is coupled to the cradle 50, for example, shown in FIG. 5. In doing so, the outer clip component 22 and inner clip component 24 apply a force, e.g., a radially inward force, directly on the handlebar 118.
In some embodiments, the foregoing steps 102-106 may be performed in a different order. For example, the cradle 50 may be assembled, then the inner clip protrusion 26 may be securely coupled to the cradle 50, then the inner clip component 24 can be positioned about the shopping cart handlebar 26 where the outer clip component 22 can be positioned about the inner clip component 24 to secure the clip mechanism 10 to the handlebar 118.
At block 108, a mobile computing device 114 is inserted in the cradle 50. The mobile computing device 114 may be a personal or store-provided electronic device such as a portable scanner, smartphone, computing tablet or pad, portable computer, global positioning system device, portable digital assistant, or any other type of portable device with a computer processor. Mobile device holder 110 can also hold non-computing devices such as a notepad or a voice recorder, or any other mobile device that can be held by mobile device holder 110.
FIG. 8 through FIG. 13 show another embodiment of a mobile device holder 110A. In particular, FIG. 8 shows a perspective view of mobile device holder 110A coupled to a handle 118 of a shopping cart 112, FIG. 9 shows a side cross-sectional view of mobile device holder 110A and mobile computing device 114 coupled to handle 118, FIG. 10 shows a simplified schematic diagram of a top plate 130 of mobile device holder 110A, which is electrically coupled to mobile computing device 114, a scanner 122, shopping cart 112, and a power source 124.
