It also should be noted that in some alternative implementations, the functions and acts noted may occur out of the order noted in the figures. For example, two figures shown in succession may in fact be executed substantially concurrently or may sometimes be executed in the reverse order, depending upon the functionality and acts involved.

[0018] As used herein, the term “about” means that dimensions, sizes, formulations, parameters, shapes, and other quantities and characteristics are not and need not be exact, but may be approximated and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill. Further, unless otherwise stated, the term “about” shall expressly include “exactly.”

[0019] The terms “customer,” and “user” refer to an entity, e.g. a human, using the safe shopping universal push bar attached to a shopping cart associated with the invention. The term user herein refers to one or more users.

[0020] The term “invention” or “present invention” refers to the invention being applied for via the patent application with the title “Safe Shopping Universal Push Bar.” Invention may be used interchangeably with push bar.

[0021] In general, the present disclosure relates to an article of manufacture for providing a personal protection device. To better understand the present invention, FIGS. 1a-b illustrate an example embodiment for to an article of manufacture for a universal push bar to create a hygienically safe shopping cart according to the present invention. The safe shopping universal push bar 100 comprises a main push bar 101 coupled to a pair of support members 105a-b in which each support member 105a-b has a clamping mechanism 102a-b on a lower end of the support member 105a-b from the main push bar 101.

[0022] The pair of claiming mechanisms 102a-b permit the push bar 100 to be attached to a shopping cart without the user having to come into contact with the shopping cart. The main push bar 101 is arranged parallel to the shopping cart push bar while being separated by the length of the support members 105a-b. The main push bar 101 may be coupled to the pair of support members 105a-b in different ways. In the embodiment of FIG. 1, the support members 105a-b are coupled to the main push bar 101 mechanically using a pair of through bolts capped by a pair of attachment nuts 106a-b. The support members 105a-b also may be mechanically coupled using a clamping collar that tightens about the main push bar. Additionally, the support members 105a-b also may be welded to the main push bar 101 to create a single device.

[0023] The main push bar 101 is shown in FIG. 1 to be a solid rod coupled between the two support members 105a-b. The main push bar 101 may also be constructed using a telescoping shaft that permits the length of the main push bar 101 to be reduced in size when carried or stored by a customer. In such an embodiment, the various segments of the telescoping push bar may include locking mechanisms, such as twist locks and lever-operated locks to hold the main push bar 101 in place while in use.

[0024] The pair of attachment members 105a-b is used to securely couple the push bar 100 to the shopping cart push bar. Examples of a push bar attached to a shopping cart are illustrated in FIGS. 2a-c and 4a-c. In the embodiment of FIG. 1, the pair of attachment members 105a-b comprise a C-shaped clamping mechanisms 102a-b having a pair of opposing clamping surfaces, a moving clamping surface 104a-b attached to a threaded rod 107a that engages a threaded hole through the opposing clamping surface of the C-shaped clamping surfaces of the attachment mechanisms 102a-b. A tightening knob 103a-b is located on an opposite end of the threaded rod 107a from the clamping surface 106a. When a user rotates the tightening knobs 103a-b, the threaded rod 107a rotates moving the clamping surface 106a either inward or outward.

[0025] If the push bar of the shopping cart is placed between the moving clamping surface and the opposing C-shaped surface of the attachment member 102a-b, the tightening knob 103a-b permits the attachment members 102a-b to be easily clamped onto the shopping cart push bar. Once shopping has been completed, rotation of the tightening knobs 103a-b in the opposite direction loosens the attachment members 102a-b from the shopping cart push bar in order for the user to remove the push bar 100 once done shopping. All of the interaction between the attachment members 102a-b and the shopping cart may occur with the user only coming into contact with the push bar 100 and the tightening knobs 103a-b.

[0026] FIGS. 2a-c illustrate other example embodiments of an article of manufacture for a universal push bar to create a hygienically safe shopping cart according to the present invention. The main push bar 101 may be made of a metal material such as steel or aluminum and may be covered with a layer of vinyl or rubber material 101. As such, the user may utilize the push bar 100 by handling the vinyl rubber, or cloth tape material covering the main push bar 101 between the pair of support members 105a-b. The push bar 100 as shown in FIGS. 2a-c is attached to a shopping cart 201 in the manner disclosed above in reference to FIG. 1.

[0027] FIG. 3 illustrates an example embodiment of an article of manufacture for a universal push bar to create a hygienically safe shopping cart according to the present invention. The example embodiment of the push bar 100 shows dimensions for a preferred embodiment. The main push bar 101 is typically between 21″-23″ in length and a ¾″ pipe. The support members 102a-b are 2 ¼″ in length to position the main push bar 101 3″ about the shopping cart push bar. The pair of support members 102a-b are between 14″-16″ apart and secured to the main push bar 101 using a ¼″ screw. The threaded member 107a connects the tightening knob 103a-b to the clamping surface 106a-b using a 1¼″ threaded screw.

[0028] FIG. 4 illustrate yet another example embodiment for an article of manufacture for a universal push bar to create a hygienically safe shopping cart according to the present invention. In this embodiment, the safe shopping universal push bar 200 is shown with the main push bar 201 being made of copper. The main push bar 101 may be made of: solid copper, copper plating or a layer of copper covering the outside surface of the main push bar 201. As such, the user may utilize the push bar 200 by handling the copper surfaces to obtain the anti-microbial benefits naturally provided from the use of copper. The push bar 200 as shown in FIG. 2. 4 is attached to a shopping cart in the manner disclosed above in reference to FIGS. 1 and 2a-c.

[0029] Even though particular combinations of features are recited in the present application, these combinations are not intended to limit the disclosure of the invention. In fact, many of these features may be combined in ways not specifically recited in this application. In other words, any of the features mentioned in this application may be included to this new invention in any combination or combinations to allow the functionality required for the desired operations.

[0030] No element, act, or instruction used in the present application should be construed as critical or essential to the invention unless explicitly described as such. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
