BACKGROUND OF THE INVENTION TECHNICAL FIELD
This invention relates to footwear and, more particularly, to an adjustably vented shoe for providing users with a means of regulating an air flow to maintain cool and dry feet throughout the day.
PRIOR ART
When we think about the tools that we use to make our livings, we tend to think about things like hammers and saws, laptop computers or pipe-wrenches, stethoscopes or jackhammers. Tools are crucial to civilization, and each of us uses tools to do our work. But as different as our jobs, and therefore our tools might be, all working people have a few things in common. We all work better after a good night's sleep. We all need food to fuel our brains and bodies, and exercise to keep us strong. We all prefer a work environment where we are respected and valued, and where the skills we bring to our work are equal to the challenges we face.
And, for many of us, work means being on our feet for hours at a time, and coming home at the end of the day with tired, aching feet. Aching feet are a consequence of what anthropologists refer to as “bipedal locomotion”: walking on two feet, being human. And while work shoes, and shoes in general, have come a long way in the last fifty years, there's still no steel-toed boot as comfortable as a sneaker, and still no work shoe as cool as a sandal. Consider the plight of a roofer who works on rooftops with hot tar and asphalt, and who must wear protective boots for this work—would this man appreciate a pair of safety boots that also kept his feet cool and dry? Added to this, the wet and damp interior of shoes give rise to fungal infections and feet odor which can be detrimental to the well being of a person subjected to work in a hot and humid environment.
Accordingly, a need remains for an apparatus in order to overcome the above-noted shortcomings. The present invention satisfies such a need by providing an adjustably vented shoe that is convenient and easy to use, is durable yet lightweight in design, is versatile in its applications, and provides a user with a means of regulating an air flow rate to maintain cool and dry feet throughout the day.
BRIEF SUMMARY OF THE INVENTION
In view of the foregoing background, it is therefore an object of the present invention to provide an adjustably vented shoe for permitting air flow to ingress and egress an interior of the shoe and thereby maintain cool and dry feet during extended use. These and other objects, features, and advantages of the invention are provided by an adjustably vented shoe including a body adapted to cover an entire user foot therein. Such a body preferably has an outer surface provided with an opening formed therethrough. The shoe further includes a first plate statically interfitted within the opening, a mesh screen statically interfitted within the opening and abutted with the first plate respectively, and a second plate adjustably engaged with the first plate respectively. Notably, the first plate and the mesh screen remain stationary while the second plate is dynamically displaced between open and closed positions relative to the first plate and the mesh screen respectively. In this manner, the mesh screen is exposed to ambient air when the second plate is displaced to the open position such that air is permitted to freely ingress and egress the shoe via the mesh screen.
In one embodiment, the mesh screen is coplanar with the first plate in such a manner that the mesh screen and first plate collectively extend along an entire surface area of the opening. The second plate may be spaced exterior of the mesh screen and thereby covers an entire surface area of the mesh screen when the second plate is disposed at the closed position.
In one embodiment, the first plate may include first, second and third sides attached to a continuously extending inner wall of the opening respectively. A fourth side may be spaced from the inner wall. In this manner, the first and second parallel sides of the mesh screen are directly connected to a first section of the inner wall and a medial side of the first plate respectively. Notably, the first section of the inner wall may be oriented parallel the medial side of the first plate.
In one embodiment, the shoe may further include a deodorant patch registered parallel to the mesh screen and statically connected to the first plate and the inner wall of the opening. Such a deodorant patch may be disposed anterior of the mesh screen and posterior of the second plate such that the deodorant patch is isolated from the ambient air when the second plate is displaced to the closed position.
In one embodiment, the second plate may be slidably reciprocated along a linear path defined within the opening. The second plate preferably has a posterior face slidably abutted against an anterior face of the first plate while the second plate is displaced between the open and closed positions. In this manner, the second plate remains aligned parallel to the first plate while the second plate is displaced between the open and closed positions.
In one embodiment, the second plate may be pivotally coupled to the first plate and selectively reciprocated along a curvilinear path extending outwardly and away from the opening. In this configuration, the second plate preferably has an anterior face selectively engaged against an anterior face of the first plate while the second plate is selectively displaced between the open and closed positions. Thus, the anterior face of the second plate may be coplanar with the anterior face of the first plate when the second plate is pivoted to the open position.
In one embodiment, the second plate is capable of being selectively reciprocated about clockwise and counter clockwise directions between the open and closed positions respectively.
The present invention may further include a method of utilizing an adjustably vented shoe for permitting air flow to ingress and egress an interior of the shoe and thereby maintain cool and dry feet during extended use. Such a method preferably includes the chronological steps of: providing a body; covering an entire user foot with the body wherein the body preferably has an outer surface provided with an opening formed therethrough; providing and statically interfitting a first plate within the opening; providing and statically interfitting a mesh screen within the opening; abutting the mesh screen with the first plate; providing and adjustably engaging a second plate with the first plate; maintaining the first plate and the mesh screen at a stationary position; dynamically displacing the second plate between open and closed positions relative to the first plate and the mesh screen respectively; and exposing the mesh screen to ambient air by displacing the second plate to the open position and thereby permitting air to freely ingress and egress the shoe via the mesh screen.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

Thus, the following claims are incorporated into the Detailed Description, with each claim standing on its own as defining separately claimed subject matter.
The below disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments which fall within the true scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
The apparatus of this invention is referred to generally in FIGS. 1-11 by the reference numeral 10 and is intended to provide an adjustably vented shoe 10 for permitting air flow to ingress and egress an interior of the shoe 10 and thereby maintain cool and dry feet during extended use. It should be understood that the adjustably vented shoe 10 may be used in a variety of environments and should not be limited to any particular indoor or outdoor activity.
Referring to FIGS. 1-11, an adjustably vented shoe 10 includes a body 11 adapted to cover an entire user foot therein. Such a body 11 preferably has an outer surface provided with an opening 12 formed therethrough. As noted in FIGS. 1-3, the opening 11 may be located at various area of the body 10. Also, multiple openings 12 may be provided in the body 10.
As perhaps best shown in FIGS. 4-11, shoe 10 further includes a first plate 13 statically interfitted within the opening 12, a mesh screen 15 statically interfitted within the opening 12 and abutted with the first plate 13 respectively, and a second plate 14 adjustably engaged with the first plate 13 respectively. Notably, the first plate 13 and the mesh screen 15 remain stationary while the second plate 14 is dynamically displaced between open and closed positions relative to the first plate 13 and the mesh screen 15 respectively. One skilled in the art understands a conventional tongue/groove configuration or guide track may be positioned along sections 20c, 20d of inner wall 20 of opening 12. Other conventional mechanism may be employed to permit linear displacement of second plate 14, well-known in the industry, without departing from the true spirit and scope of the present invention.
FIGS. 4 and 5 show second plate 14 at the closed position. FIGS. 6-9 and 11 shown second plate 14 at the open position. In this manner, the mesh screen 15 is exposed to ambient air when the second plate 14 is displaced to the open position such that air is permitted to freely ingress and egress (circulate) throughout the shoe 10 via the mesh screen 15. The advantage of such a structural configuration permits the user to selectively move the second plate 14 between the open and closed positions, as desired. Further, by maintaining the first plate 13 and mesh screen 15 at a consistently stationary position, the second plate 14 is unobstructed and freely reciprocates or pivots during extended activities.
In one embodiment, as perhaps best shown in FIGS. 4-9, the mesh screen 15 is coplanar with the first plate 13 in such a manner that the mesh screen 15 and first plate 13 collectively extend along an entire surface area of the opening 12. The second plate 14 may be spaced exterior of the mesh screen 15 and thereby covers an entire surface area of the mesh screen 15 when the second plate 14 is disposed at the closed position. Such a structural configuration provides the advantage of ensuring the mesh screen 15 remains unencumbered when the second plate 14 is displaced to the open position. For example, second plate 14 is prohibited from becoming stuck in the opening while at the closed position. Also, second plate 14 is thereby free to reciprocate along the width of opening 12 without being urged through opening 12 during an accidental impact because first plate 13 and mesh screen 15 shield opening 12 and prevent second plate 14 from being undesirably pushed into the interior of the shoe 10.
In one embodiment, the first plate 13 may include first 13a, second 13b and third 13c sides attached to the continuously extending inner wall 20 of the opening 12 respectively. A fourth side 13d may be spaced from the inner wall 20. In this manner, the first 15a and second 15b parallel sides of the mesh screen 15 are directly connected to a first section 20a of the inner wall 20 and a medial side 13d of the first plate 13, respectively. Notably, the first section 20a of the inner wall 20 may be oriented parallel the medial side 13d of the first plate 13. The advantage of such a structural configuration ensures that mesh screen 15 is maintains a continuous frictional forces along sides 15a, 15b thereof. Mesh screen 15 thereby remains registered along a planar configuration spaced posterior to second plate 14 and is prevented from interfering with second plate 14 linear displacement, as perhaps best shown in FIGS. 8-9.
In one embodiment, the shoe 10 may further include a deodorant patch 16 registered parallel to the mesh screen 15 and statically connected to the first plate 13 and the inner wall 20 of the opening 12. Such a deodorant patch 16 may be disposed anterior of the mesh screen 15 and posterior of the second plate 14 such that the deodorant patch 16 is isolated from the ambient air when the second plate 14 is displaced to the closed position. By positioning deodorant patch 16 anterior of mesh screen 15, patch 16 becomes intercalated between mesh screen 15 and second plate 14. Such a sandwiched location shelters patch 16 from prematurely losing its scent as well as from foreign liquids that can soak/dilute the aroma concentration of patch 12.
As perhaps best shown in FIGS. 8-9, the second plate 14 may be slidably reciprocated along a linear path 17 defined within the opening 12. The second plate 14 preferably has a posterior face 14a slidably abutted against an anterior face 13e of the first plate 13 while the second plate 14 is displaced between the open and closed positions. The advantage of such a structural configuration ensures the second plate 14 remains aligned parallel to the first plate 13 while the second plate 14 is displaced between the open and closed positions.
As perhaps best shown in FIG. 10, in one embodiment, the second plate 14 may be pivotally coupled to the first plate 13 and selectively reciprocated along a curvilinear path 18 extending outwardly and away from the opening 12. In this configuration, the second plate 14 preferably has an anterior face 14b selectively engaged against the anterior face 13e of the first plate 13 while the second plate 14 is selectively displaced between the open and closed positions. Thus, the anterior face 14b of the second plate 14 may be coplanar with the anterior face 13e of the first plate 13 when the second plate 14 is pivoted to the open position.
In one embodiment, the second plate 14′ is capable of being selectively reciprocated about clockwise and counter clockwise directions 19 between the open and closed positions respectively, as perhaps best shown in FIG. 11. Mesh screen 15′ remains stationary during such rotational movement.
The present invention may further include a method of utilizing an adjustably vented shoe 10 for permitting air flow to ingress and egress (circulate) through an interior of the shoe 10 and thereby maintain cool and dry feet during extended use. Such a method preferably includes the chronological steps of: providing a body 11; covering an entire user foot with the body 11 wherein the body 11 preferably has an outer surface provided with an opening 12 formed therethrough; providing and statically interfitting a first plate 13 within the opening 12; providing and statically interfitting a mesh screen 15 within the opening 12; abutting the mesh screen 15 with the first plate 13; providing and adjustably engaging a second plate 14 with the first plate 13; maintaining the first plate 13 and the mesh screen 15 at a stationary position; dynamically displacing the second plate 14 between open and closed positions relative to the first plate 13 and the mesh screen 15 respectively; and exposing the mesh screen 15 to ambient air by displacing the second plate 14 to the open position and thereby permitting air to freely ingress and egress (circulate) the shoe 10 via the mesh screen 15.
While the invention has been described with respect to a certain specific embodiment, it will be appreciated that many modifications and changes may be made by those skilled in the art without departing from the spirit of the invention. It is intended, therefore, by the appended claims to cover all such modifications and changes as fall within the true spirit and scope of the invention.
In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the present invention may include variations in size, materials, shape, form, function and manner of operation.
