The present disclosure relates generally to footwear articles. In particular, metal detecting footwear is described.
Metal detecting is an activity done for useful endeavors and for recreation. When metal detecting, one searches an area for metal objects using a metal detector. Known metal detectors and approaches to metal detecting are not entirely satisfactory.
For example, existing metal detectors must be carried by hand, which limits a person's ability to use his or her hands for other purposes. Further, existing metal detectors are somewhat heavy and fatiguing. The length of existing metal detectors makes them awkward to carry and prone to getting caught in underbrush and trees when walking in nature with them.
The manner in which conventional metal detectors are used is another limiting feature of them. Existing metal detectors must be manually directed over the ground. The length of conventional metal detectors can make it difficult to direct the metal detector towards a desired location because branches, objects, and underbrush can obstruct the metal detector.
Having to actively direct the metal detector over the ground can become mentally fatiguing and inconvenient. It would be desirable to have a way to passively detect metal objects as one walks along the ground or through water without having to actively direct a metal detector over the ground.
Conventional metal detectors represent a separate item that must be brought along with a person if he or she wants to detect metal objects. It would be desirable if a person could detect metal objects without having to remember to bring and pack a distinct metal detector.
Thus, there exists a need for improvements in the field of metal detecting and in the design of known metal detectors. Examples of new and useful metal detecting footwear articles relevant to the needs existing in the field are discussed below.
The present disclosure is directed to footwear articles including an upper, a sole, and a metal detecting system. The sole is secured to the upper and defines a cavity. The metal detecting system is secured to the sole in the cavity. In some examples, the footwear article includes an indicator.
The disclosed footwear articles will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
Throughout the following detailed description, examples of various footwear articles are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
The following definitions apply herein, unless otherwise indicated.
“Substantially” means to be more-or-less conforming to the particular dimension, range, shape, concept, or other aspect modified by the term, such that a feature or component need not conform exactly. For example, a “substantially cylindrical” object means that the object resembles a cylinder, but may have one or more deviations from a true cylinder.
“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional elements or method steps not expressly recited.
Terms such as “first”, “second”, and “third” are used to distinguish or identify various members of a group, or the like, and are not intended to denote a serial, chronological, or numerical limitation.
“Coupled” means connected, either permanently or releasably, whether directly or indirectly through intervening components.
“Communicatively coupled” means that an electronic device exchanges information with another electronic device, either wirelessly or with a wire-based connector, whether directly or indirectly through a communication network.
“Controllably coupled” means that an electronic device controls operation of another electronic device.
Metal Detecting Footwear
With reference to the figures, metal detecting footwear will now be described. The footwear articles discussed herein function to detect metal objects.
The reader will appreciate from the figures and description below that the presently disclosed footwear articles address many of the shortcomings of conventional metal detectors and approaches to metal detecting. For example, the metal detecting footwear described herein does not need to be carried by hand like a conventional metal detector. As a result, the metal detecting footwear described below frees a user's hands for other purposes.
Further, the weight of the metal detecting systems in the footwear described below is low to the ground and borne by a person's legs rather than a person's hand and arms as occurs with conventional metal detectors. Leg muscles are stronger and more robust than arm and hand muscles; thus, the metal detecting footwear described herein is less fatiguing to carry and use than existing metal detectors.
The metal detecting systems incorporated into the footwear discussed below are compact and self-contained. Their compact and self-contained form makes them convenient to carry and helps avoid them getting caught in underbrush and trees when walking in nature with them.
The metal detecting footwear below does not need to be manually directed over the ground. As a result, the metal detecting footwear dispenses with the need to concentrate on directing a handheld metal detector and avoids the associated mental fatigue and inconvenience. Instead, the metal detecting footwear described herein desirably provides a way to passively detect metal objects as one walks along the ground without having to actively direct a metal detector over the ground.
Conveniently, one does not need to pack and remember to bring a distinct metal detector with the metal detecting footwear discussed in this document. Whenever one is wearing the footwear described below, he or she can selectively activate he metal detecting features of the footwear to detect metal objects when desired without requiring a separate device.
