2. Background Information

Smartphones and other electronic mobile devices have become increasingly popular for managing multiple aspects of one's daily life. One such aspect is shopping. For example, shoppers have increasingly been using electronic mobile devices to manage shopping lists or to otherwise enhance the shopping experience.

Many companies are trying to engage consumers directly at the point of purchase (e.g., at a supermarket or other retail location). Through mobile GPS and opt-in programs software is being actively developed to display advertisements, provide scannable codes (in the form of, e.g., barcodes, RFID codes, QR codes and the like) and offer messages and promotions to consumers as they move through the retail location. A challenge to such engagement is that consumers often store their devices in their pockets, purses or elsewhere, thereby inhibiting consumer interaction and foreclosing to vendors marketing directed at the consumer. Additionally, the variety of sizes of mobile devices makes it difficult to have a device that works for mobile devices of different types and dimensions.

As such, a need has arisen for a system to not only hold, but to display the screen of such mobile devices to the shopper, so that the shopper can safely push a shopping cart while still being able to view the device.

DETAILED DESCRIPTION

In view of the foregoing, the present disclosure, through one or more of its various aspects, embodiments and/or specific features or sub-components, is thus intended to bring out one or more of the advantages as specifically noted below.

The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied in practice.

Referring now to the drawings wherein like characters represent like elements. FIGS. 1-18 show a mobile device holder 210 according to the first aspect of the present disclosure. As used herein, “mobile device” can mean any mobile device, including but not limited to a tablet computer (such as, e.g., an iPad), a smartphone (such as, e.g., a Blackberry, iPhone, Android), personal digital assistant (PDA), a global positioning satellite (GPS) device, a portable music player (such as, e.g., an iPod), an e-reader, a palmtop computer, a laptop computer, a wireless/cellular telephone, a camera, a pager, a personal trusted device, a portable video game system, and a web appliance (such as, e.g., an iPod Touch). Nor is the present invention limited to electronic devices, e.g., a notepad or coupon book may be used with the present invention.

The mobile device holder 210 includes a holding portion 212, a pivot assembly 214 and a mount 218. although in alternative embodiments. the pivot assembly may he excluded. The holding portion 212 includes a holding portion body 22 and a lower shelf 6. The lower shelf 6 may be unitarily formed with the holding portion body 22 from a single piece of material, or may be fastened to the holding portion body. According to a feature, the holding portion body 22 includes a front mounting plate 1 and a rear mounting plate 2 which are fastened together to form the holding portion. An upper shelf 10 extending in a plane generally parallel with the lower shelf 6 is provided at the top of the holding portion body 22, and a slide guide 3 depending from the upper shelf generally at a 90 degree angle is provided. As shown in FIG. 5, the slide guide 3 extends between the front mounting plate 1 and rear mounting plate 2, which allows the upper shelf 10 to slide toward and away from the lower shelf 6. It is appreciated by those skilled in the art that in alternative embodiments, only one housing plate may be provided and the slide guide 3 may be slidably affixed to a single housing plate.

According to a feature of the disclosure, the upper shelf 10 is downwardly biased towards the lower shelf 6 by a spring 14. For example, the spring 14 may be a constant force tape spring wound about pivot shaft 13, and having one end affixed to a base of the slide guide 3 by a spring holding plate 20, and having another end affixed to the holding portion. Pulling the upper shelf 10 in direction Z away from the lower shelf 6 extends the spring 14 and creates tension therein, and releasing the extended upper shelf allows the spring to pull the upper shelf toward the lower shelf in direction Z, until the slide guide 3 reaches its travel limit (when not holding a mobile device). The spring 14 provides adequate tension to securely hold a mobile device while limiting movement and shaking, while still allowing a user/shopper to easily remove their device from the mobile device holder 210.

The mobile device holder 210 is configured to hold a mobile device. As shown in FIGS. 15-18, one way the mobile device holder can hold a mobile device is by removably clamping the mobile device D1, D2 between the upper shelf 10 and lower shelf 6, such that the upper shelf contacts one edge of the mobile device and the lower shelf contact another edge of the mobile device. In this way, the mobile device holder 210 can securely and removably hold mobile devices of varying widths or heights. As an example, FIGS. 15-16 show a smartphone Dl such as an iPhone being held by the mobile device holder 210 in an upright. or portrait. position. and FIGS. 17-18 show a tablet D2 such as an iPad being held by the mobile device holder. The lower shelf 6 may be provided with a pad 7 to contact a side of the mobile device and similarly, the upper shelf 10 may be provided with a pad 11 to contact an opposite side of the mobile device. The pads 7, 9, 11 may each be a soft covering in order to avoid scratching of mobile device D1, D2, and/or may be elastomeric to prevent displacement of the mobile device from the holder 212. Further, each pad 7, 9, 11 may have a thickness which decreases in a depth direction (i.e., a direction Y shown in FIG. 14) of the respective shelf on which it is mounted.

According to a feature of the disclosure, also provided may be a flip shelf 8 pivotably attached to the holding portion body 22 on opposite sides thereof. As shown in the Figures. the flip shelf 8 may include a pair of flip shelves independently pivotable or pivotable together via a flip shelf shaft 8a, or may include a single shelf extending the width of the holding portion body 22.

When the mobile device holder 210 it to hold a mobile device having a height or width less than the distance between the upper shelf 10 and the lower shelf 6 when the upper and lower shelves are nearest each other, the flip shelf 8 may be flipped down into a holding position so that the downwardly-biased upper shelf contacts one edge of the mobile device D1 and the flip shelf 8 contacts another edge of the mobile device to securely and removably hold the mobile device between the upper and flip shelves, as shown in FIGS. 13-14. FIGS. 2, 4, 5, 6A, 6B, 13 and 14 show the mobile device holder with the flip shelf 8 in the holding position. and FIGS. 1, 7A. 7B, 8A, 813, 9, 10A, 10B, 11, 12A, 12B and 15-18 show the mobile device holder with the flip shelf in a stowed position.

As shown in FIGS. 7A-7B, a flip shelf support 15 located on either side of the holding portion body 22 prevents downward pivoting of the flip shelf 8 so that the flip shelf 8 is maintained in a plane generally parallel with the plane of the upper shelf 10 when the flip shelf is in the holding position (i.e., the flip shelf is prevented from pivoting outside of the range between the holding position and the stowed position, when the flip shelf is in the holding position). Further, as shown in FIGS. 2-3 and 6A-6B, a flip shelf stop 16 located on either side of the holding portion body 22 prevents backward pivoting of the flip shelf so that the rearmost position of the flip shelf 8 is in a plane generally parallel with the plane of the holding portion body when the flip shelf is in the stowed position. Also, as shown in FIGS. 6A-6B flip shelf lock 17 located on either side of the holding portion body 22 prevents unintentional forward pivoting of the flip shelf so that the flip shelf is maintained in the plane generally parallel with the plane of the holding portion body when the flip shelf is in the stowed position. The flip shelf lock 17 may be outwardly biased to contact an underside of the flip shelf 8 (best shown in FIG. 7B), when the flip shelf is in the stowed position. This way, the flip shelf does not interfere when a larger mobile device D2 or an upright/portrait mobile device D1 is held between the upper shelf 10 and lower shelf 6, as shown in FIGS. 15-18. Thus, the upper shelf 10 is biased downward such that when the flip shelf 8 is in the holding position, a smaller mobile device D1 is removably and securely held between the upper shelf 10 and the flip shelf 8 as shown in FIGS. 13-14, and such that when the flip shelf 8 is in the stowed position, a larger mobile device D2 (or a smaller mobile device in portrait orientation) is removably securely held between the upper shelf 10 and the lower shelf 6, as shown in FIGS. 15-18.

The pivot assembly 214 is affixed to the base 218, and allows the housing portion 212 to pivot about a pivot axis P (extending in a direction generally parallel to axis X) between an upright position (shown in, e.g., FIGS. 1-2 and 13-18) and a stowed position (shown in FIGS. 8A-8C, 11 and 12A-12B). The base (or mount) 218 has a pair of arms 243 for rotatably supporting the pivot shaft 13 therebetween. As shown in FIG. 3, a pair of guide disks 19 is provided on opposite sides of the pivot shaft 13 to guide the pivoting motion and provide a pivoting range of the housing portion 212. The pivot assembly may be provided with a ball plunger 18 having an outwardly-biased spring-loaded ball 18a. During pivoting of the housing portion 212, the ball 18a is guided through a generally C-shaped channel and in the upright position the ball 18a is inserted into aperture 19a of guide disk 19. The housing portion 212 is maintained in the upright position until pressure is applied to the housing such that the ball 18a is pushed inwardly and the housing portion is allowed to rotate. This way, the housing portion 212 may be pivoted such that a screen of the mobile device may be oriented to a user's desired viewing angle, and inadvertent pivoting of the mobile device holder 210 (due to, e.g., shaking) is avoided. Further, by pivoting the housing portion downward to the stowed position, the mobile device holder avoids interfering with placement of items in the shopping cart. Mounting hardware 12 such as screws secure the guide disks 19 against rotation about axis P, and a center screw 13a or other suitable fastener is fitted into the pivot shaft 13 to secure the pivot shaft between the arms 243 of the mount 218.

As shown in, e.g., FIGS. 9-12B, the mobile device holder 210 is preferably attachable to a pivotable secondary basket 102 of a shopping cart 100. The secondary basket 102 of a shopping cart 100 is typically positioned in front of the end gate 104 and within the main basket 106. In the shopping art, a folding child seat 108 may be positioned between the secondary basket 102 and the end gate 104, such that the child seat may be folded when the secondary gate is pulled toward the cart pusher/shopper and against the end gate to make more room for items in the main basket 106. This arrangement also allows for the end gate 104. folding child seat 108 and secondary basket 102 to pivot together toward the front of the shopping cart 100 when another shopping cart is nested with the shopping cart. By mounting the mobile device holder 210 to the top of the secondary basket 102, nesting of the shopping carts is still possible, since the end gate 104, folding child seat 108 and secondary basket 102 pivot together, thereby conserving floor space. By mounting the mobile device holder 212 to the secondary basket 102, the mobile device Dl, D2 is close enough to the user/shopper for easy viewing and/or easy engagement with a mobile device touch screen, whereas mounting a mobile device holder to a shopping cart handle could force the user/shopper to look down at an uncomfortable angle and/or take his/her eyes off the view ahead, and/or interfere with the nesting of shopping carts.

The mount 218 also includes a bumper 245 that protrudes toward the front of the shopping cart 100 (preferably beyond the other components of the device holder 210), in order to protect the other components of the device holder when shopping carts are pushed or banged together (e.g., during a cart nesting operation). The mount 218 can be mounted to the shopping cart 100 using a mounting bracket 244 secured by bolts or other methods of attachment such that the secondary basket 102 is sandwiched between the mount 218 and the mounting bracket. It is also understood by those of skill in the art that the mobile device holder 210 may be mounted to the shopping cart 100 by other methods than the mounting bracket 244 and bolts, including but not limited to a bayonet-type attachment, spring-loaded attachment, and the like. In an embodiment, the mounting bracket 244 is generally L-shaped (as shown) or U-shaped, in order to prevent sideways displacement of the mobile device holder 210. Alternatively, the mobile device holder 210 may be integrally formed with the secondary basket such that mounting hardware is not needed.

The mobile device holder 210 may be made of any suitable material rigid enough to hold a mobile device, including but not limited to plastic and metal. Further, while the embodiments described herein refer to the mobile device holder 210 attachable to a shopping cart 100, it is appreciated by those skilled in the art that the mobile device holder 210 is attachable to any structure which may be mobile or stationary, such as an automobile, bicycle, a stationary exercise machine, and the like.
