BACKGROUND OF THE INVENTION

[0001] The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.

TECHNICAL FIELD

[0002] The present invention relates generally to the field of footwear of existing art and more specifically relates to massaging footwear.

RELATED ART

[0003] To massage is to repeatedly apply pressure to the body as a therapeutic technique. Massage techniques may be done with hands, fingers, feet, other parts of the body, or a mechanical device. A massage may be applied to various parts of the body. A massage may be useful for treating physical pain, discomfort, and stress. Potential benefits for a recipient may also include reduced anxiety, depression, blood pressure, and heart rates. Some types of massage therapy have been developed to target specific combination of massage points in order to treat specific types or areas of pain.

[0004] Unfortunately, a massage usually requires a recipient to maintain a stationary position so that a massage therapist or a machine may massage the recipient. This may require devoting an unsuitable amount of time without being able to complete other tasks simultaneously. A suitable solution is desired.

[0005] U.S. Pat. No. 8,632,481 to Zheng Shi et al relates to a therapeutic shoe. The described therapeutic shoe includes a main body, a sole located at one side of the main body, a vibration layer, and a power generating module. The vibration layer is located between the main body and the sole. The power generating module includes a power generating unit, a rectifying circuit and a vibration device, which are electrically connected in series. The power generating unit generates and induces induced current.

SUMMARY OF THE INVENTION

[0006] In view of the foregoing disadvantages inherent in the known footwear art, the present disclosure provides a novel footwear having multiple massage devices and method. The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a footwear having multiple massage devices and method.

[0007] A footwear is disclosed herein. The footwear includes a sole, a plurality of massage units, and a controller. The sole provides a support to the underside of a user’s foot when the user is wearing the footwear. The massage units each include a channel, a plunger, a spring, and an actuator. The plunger is disposed within the channel and may slide within it linearly. The plunger has a shaft which terminates in an applicator, the applicator being round and configured to provide pressure to the user’s foot. The spring is configured to maintain the plunger within a contact- position when at rest. This contact-position occurs when the plunger is maximally distal to the spring. The actuator is able to draw the plunger against the spring and release the plunger in repetition when energized, enacting a massaging action. The controller is able to selectively engage the actuators.

[0008] According to another embodiment, a method of selectively massaging a portion of a user’s foot is also disclosed herein. The method of selectively massaging a portion of a user’s foot includes providing the above-described footwear, predetermining a first-selection of massage- units chosen from the massage-units, energizing the actuators corresponding to the first-selection of massage-units, actuating the first-selection of massage-units, and optionally, predetermining additional selections of massage-units.

DETAILED DESCRIPTION

[0017] As discussed above, embodiments of the present disclosure relate to a footwear and more particularly to a footwear having multiple massage devices and method as used to improve the massaging of a foot of a user.

[0018] Generally, the footwear includes a sole with a plurality of massage-units attached to the sole. A controller may regulate operation of the massage-units. The massage-units protrude upwardly to engage a foot of a user resting on top of the sole within the footwear. Each massage unit includes a plunger riding within a channel, an actuator beneath the plunger which may retract the plunger away from the user’s foot, and a coil spring separating the plunger from the actuator. The coil spring maintains the plunger in a position distal to the actuator. The plunger is limited in its travel and may not pass beyond a stop in the channel. With this structure, repeatedly energizing and deenergizing the actuator of one massage unit may cause the plunger to repeatedly reciprocate in a massaging action against the user’s foot while in use. In a preferred embodiment, the controller contains a program for selecting multiples of the massage-units as desired by a user. This may be accomplished by an external device able to customize programs for the controller or may be integral to the controller and the footwear in some embodiments. This may enable a user to target specific regions of the user’s foot for specific therapies and applications.

[0019] In one embodiment, the disclosure may further include a software program, particularly an application for use with a mobile device or other computing device. The program may include a user interface for programming and selecting patterns for targeting specific regions of the user’s foot while using the footwear. The program may enable the computing device to be in wireless communication with the footwear such that the computing device can initiate the massaging action of the footwear in accordance with pre-programmed patterns. In particular, the user interface may provide a user with options for specified zone therapies for activating particular regions of the footwear corresponding to regions of the foot. In one example, a zone therapy program may be selected by a user to engage massage units corresponding to the innermost centers of both the left and right feet. In some therapies, this may correspond to a particular therapeutic application, such as reducing pain to the kidneys of the user of the footwear. Additional features engagable by the user interface may include selectable rates of massage unit pulsation or a constant pressure mode. Built-in programs may be based upon in-use reflexology practices, as well as customizable programs in some embodiments. The software program may also include tutorials and other educational features.

[0020] Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-4, various views of a footwear 100.

[0021] FIG. 1 shows a footwear during an 'in-use' condition 50, according to an embodiment of the present disclosure. Here, footwear 100 may be beneficial for use by a user 40 to selectively massage a portion of a foot of a user. As illustrated, footwear 100 may include sole 110, insole 160, plurality of massage-units 120, controller 130, and cuff 140. Footwear 100 may be able to massage foot 10 of user 40. Sole 110 may be configured to support underside 15 of foot 10 of user 40, with plurality of massage-units 120 being embedded within sole 110. Insole 160 may be disposed on top of sole 110, such that insole 160 provides cushioning between foot 10 and sole 110. Insole 160 may be malleable and may be configured to cushion foot 10 of user 40 against plurality of massage-units 120. Thereby, plurality of massage-units 120 may be able to provide pressure via a massaging action to foot 10 through displacement of insole 160. In alternative embodiments, plurality of massage-units 120 may pass through insole 160. Controller 130 may be in electrical communication with plurality of massage-units 120 and may be configured to selectively engage one or more of plurality of massage-units 120. Preferably, footwear 100 is a boot as shown.

[0022] FIG. 2 shows footwear 100 of FIG. 1, according to an embodiment of the present disclosure. As above, footwear 100 may include plurality of massage-units 120. Each of plurality of massage-units 120 may include channel 122, plunger 124, spring 126, and actuator 128. Plunger 124 may be configured to slide within channel 122 and may have shaft 125 terminating in applicator 127. Applicator 127 may be round in a preferred embodiment and may be configured to provide pressure to foot 10 (FIG. 1) when actuator 128 is energized. In alternative embodiments applicator 127 may be flat or have other contours. Spring 126 may be configured to maintain plunger 124 in contact-position 129, such that contact-position 129 may be distal to spring 126. Spring 126 may be a coil spring able to be compressed between plunger 124 and actuator 128. Actuator 128 may be configured to draw plunger 124 against spring 126 and release plunger 124 in repetition, thereby effecting a massaging action when foot 10 (FIG. 1) is placed against plurality of massage-units 120 and alternatively insole 160 (FIG. 1). Channel 122 of each of plurality of massage-units 120 is characterized by channel-axis 174, channel 122 being a cylinder, such that channel 122-axis passes through the center of channel 122. Preferably, channel 122 and plunger 124 are each cylindrical, such that plunger 124 is nested within channel 122 may only travel linearly within channel 122 along channel-axis 174. Plunger 124 of the massage unit may further include flange 170. Channel 122 of the massage unit may also further include constriction 172. Flange 170 may be annular and concentric to plunger 124, while constriction 172 may likewise be annular and concentric to channel 122. Flange 170 may be structured and arranged to impinge upon constriction 172, having dimensions that prevent flange 170 from passing beyond constriction 172, thereby retaining plunger 124 within channel 122. Flange 170 may be configured to prevent plunger 124 from leaving channel 122 despite forces being enacted upon plunger 124 by spring 126 and actuator 128. Preferably, actuator 128 is an electromagnet configured to draw plunger 124 against spring 126 when energized. Channel 122, plunger 124, spring 126, and actuator 128 may all be cylindrically shaped and may each be arranged concentrically to one another. [0023] FIG. 3 is a perspective view of footwear 100 of FIG. 1, according to an embodiment of the present disclosure. Cuff 140 may itself include aperture 142. Aperture 142 may be sufficiently large for ankle 30 (FIG. 1) of user 40 (FIG. 1) to pass through aperture 142. Cuff-axis 144 may pass centrally through aperture 142. Cuff-axis 144 may be disposed approximately parallel to cylinder-axis 174 (FIG. 2). Footwear 100 may further include electric resistance heater 150. Electric resistance heater 150 may be configured to produce heat when energized and may be disposed within cuff 140 of footwear 100. In one embodiment, cuff 140 of footwear 100 may be elastic. In another embodiment, cuff 140 of footwear 100 may include exterior 146, strap 148, and hook-and-loop fastener 149. Hook-and-loop fastener 149 may be configured to affix strap 148 to exterior 146, such that strap 148 may circumscribe cuff 140, and may constrict cuff 140 about ankle 30 (FIG. 1) of user 40 (FIG. 1) when hook-and-loop fastener 149 is engaged.

[0024] FIG. 4 is a perspective view of footwear 100 of FIG. 1, according to an embodiment of the present disclosure. Plurality of massage units 120 may be in electrical communication with power source 190, switching means 192, and controller 130 (FIG. 1). Power source 190 may be able to selectively engage each of plurality of massage-units 120 independently via controller 130 (FIG. 1). In this way, a specific combination of plurality of massage-units 120 may be engaged in order to target and massage a particular area of the foot as desired by user 40 (FIG. 1). In one embodiment, controller 130 (FIG. 1) is programmable, such that user 40 (FIG. 1) may select customizable combination 180 of the plurality of massage units 120 to energize while in use. Power source 190 may be in electric communication with controller 130 and each of actuators 128 (FIG. 2) in combination, such that the power source 190 may selectively engage each of actuators 128 (FIG. 2) independently via controller 130. Preferably, power source 190 is a battery. Switching means 192 may enable user 40 (FIG. 1) to selectively connect the power source 190 to plurality of massage-units 120 manually.
