Definitions

  • the present invention relates to articles of footwear, in particular articles of footwear having improved ventilation characteristics.
  • a first aspect of the present invention includes an article of footwear as disclosed in claim 1.
  • a second aspect of the invention includes a protective toe cap for an article of footwear as disclosed in claim 12.
  • the toe cap is rigid and has strength characteristics sufficient to satisfy ASTM F2413-11.
  • the inventions disclosed herein include, in general, various types of protective footwear that utilize ventilation and/or safety structures to provide improved breathability and safety for a user of the footwear.
  • the footwear disclosed herein utilizes an improved protective toe cap 20, as shown in Figs. 1-5 , along with various vents and/or heat channels to provide footwear 10 with effective protection for a user's toe area, as well as improved ventilation.
  • Such footwear 10 may also use other protective structures, such as a metatarsal guard 70 that itself has vents or other mechanisms, for providing ventilation.
  • Figs. 1-5 are various views of a toe cap 20, in accordance with an embodiment of the invention.
  • Toe cap 20 is shaped to fully cover a user's toes and provide protection therefor.
  • toe cap 20 is shaped as a hemi-dome in some embodiments.
  • Toe cap 20 includes an open underside 24 sized to accommodate a user's toes, and has a protrusion 22 forming a ventilation channel 23 along underside 24. Although a single protrusion 22 is shown, multiple protrusions forming multiple ventilation channels are equally possible and contemplated by the present invention.
  • Such protrusions may be arranged directly adjacent one another (e.g ., in the center of toe cap 20), or may be spaced apart from each other (e.g ., a protrusion substantially centered on toe cap 20, as shown in Fig. 1 , and one or more protrusions along the sides of toe cap 20).
  • Protrusion 22 of Figs. 1-5 extends from a midfoot side 27 of toe cap 20 towards a forefoot side 28 of toe cap 20 and tapers in the direction of forefoot side 28.
  • a height of channel 23 is at a maximum at midfoot side 27 of toe cap 20 and progressively decreases in the direction of forefoot side 28 until protrusion 22 and channel 23 disappear along underside 24 of toe cap 20.
  • protrusion 22 is shaped as a quadrangle, although it could be semi-circular, triangular, hexagonal, pentagonal, polygonal, or any other shape that adequately provides a ventilation channel 23.
  • Toe cap 20 also includes a lower lip 26 that extends around the perimeter of underside 24. Lip 26 may be positioned in footwear under a user's foot and be utilized for attaching toe cap 20 to such footwear, as described in more detail below.
  • Toe cap 20 is, in an embodiment, composed of a metal or metal alloy material (e.g ., titanium) or any other material of a sufficient strength to satisfy safety standards for protective footwear, such as ASTM F2413-11.
  • Toe cap 20 can be incorporated into a variety of different types of footwear, with or without additional ventilation characteristics, to allow for improved ventilation and breathability in the footwear.
  • Various embodiments of such footwear are shown throughout in Figs. 6-16 (with certain components of such footwear shown in isolation in those figures).
  • FIG. 6 a first variant of footwear 110 is shown in Fig. 6 .
  • Footwear 110 includes all standard aspects of normal footwear, including but not limited to an outsole 117, an upper 119 attached to outsole 117, forefoot 112, arch 114, and heel 116 regions, and a tongue 118 forming part of upper 119.
  • footwear 110 includes such components as is apparent in the figures ( e.g ., laces, etc.)
  • footwear 110 also includes a toe cap 20 embedded within its forefoot region 112.
  • Toe cap 20 is incorporated into the toe region of footwear 110 and is arranged with its lip 26 adjacent outsole 117 and its protrusion 22 positioned above the user's toes.
  • Toe cap 20 may therefore provide protection for a user's toes against, for example, a falling object and also allow for improved ventilation via its protrusion 22 and ventilation channel 23.
  • tongue 118 of footwear 110 may also include an air vent channel 30 that, in an embodiment, forms a continuation of channel 23 of protrusion 22 of toe cap 20.
  • tongue 118 may include an air vent channel 30 that extends longitudinally along tongue 118, and protrusion 22 may be shaped and sized to be positioned within vent channel 30 of tongue 118 so that a continuous air vent channel is formed along forefoot region 112 and arch region 114 of footwear 110.
  • air vent channel 30 of tongue 118 terminates in a heat egress port 32 having a series of perforations 36 for allowing heat, moisture, etc. to escape channel 30.
  • heat and/or moisture trapped in forefoot region 112 of footwear 110 may be allowed to escape through channel 23 of toe cap 20, into channel 30 of tongue 118 (which in an embodiment form a substantially continuous channel), and out of heat egress port 32.
  • air vent channel 30 of tongue 118 may be open in the direction of a user's foot (e.g., like channel 23 of toe cap 20), or in other embodiments it may be closed by way of a mesh or other fabric covering vent channel 30.
  • Meshes or other breathable fabrics may increase the comfort level of footwear 110 in the area of channel 30 of tongue 118 and channel 23 of toe cap 20. Indeed, to be clear, such meshes and fabrics as described above may extend over both channel 30 of tongue 118 and channel 23 of toe cap 20, in certain embodiments.
  • air vent channel 30 may be formed on a leather overlay component 40 that is engaged with a leather underlay 38 attached under the eyestay quarter of footwear 110.
  • footwear 110 may provide improved ventilation for safety/protective footwear by allowing heat to escape footwear 110 through channel 23 of toe cap 20, into air vent channel 30 of tongue 118, and out of heat egress port 32.
  • toe cap 20 provides adequate safety for a user's toes and protects the toes from injury.
  • FIG. 7 A second variant of footwear 110' is shown in Fig. 7 . Due to the similarities between footwear 110 of Fig. 6 and footwear 110' of Fig. 7 , like reference numerals refer to like elements in this embodiment (although a prime designation is added to the reference numerals of Fig. 7 ), and predominantly the differences between footwear 110, 110' are discussed below.
  • Footwear 110' is different from footwear 110 in that footwear 110', in addition to having a heat egress port 32', also includes an air ingress port 34'.
  • Air ingress port 34' is composed of a series of perforations 36', in an embodiment, and it allows air to flow into channel 30' of tongue 118', through channel 30', and subsequently out of heat egress port 32'. During this process, heat from the user's toes may also circulate or travel through channel 23 of toe cap 20 and into channel 30' of tongue 118'.
  • footwear 110' provides additional ventilation characteristics as compared to footwear 110.
  • footwear 110' may include any of the features of footwear 110 (e.g ., meshes or fabric over channel 30', an open channel 30' facing the user's foot, toe cap 20 within footwear 110', etc.)
  • Footwear 110", 110'” each include an air ingress port 34", 34"', but such ports are constructed differently than ingress port 34' of the previous embodiment.
  • air ingress port 34" of footwear 110" of Fig. 8 includes a series of openings 42" that define air ingress port 34".
  • channel 30" of tongue 118" is closed in an outward direction along tongue 118" until heat egress port 32" is reached.
  • air ingress port 34'" of footwear 110"' it includes a single opening 42'" as well as perforations 36'" along part of the length of tongue 118"'.
  • footwear 110", 110' may include any of the features of footwear 110, 110' described previously such as, for example, an open channel 30", 30'" in the direction of the user's foot, a channel 30", 30'” covered by a mesh or breathable fabric, toe cap 20 within footwear 110", 110"', and/or other features not explicitly detailed here.
  • Fig. 11 depicts footwear 210, according to another embodiment of the invention. Due to the similarities between the previous variants of footwear and footwear 210, like reference numerals refer to like elements in this embodiment (although in the 200-series of numbers), and predominantly the differences between each footwear embodiment is discussed below.
  • Footwear 210 includes toe cap 20, as with each of the previous embodiments.
  • Toe cap 20 is shown in detail in the exploded view of Fig. 11 .
  • Housing 250 Positioned over toe cap 20, however, is a housing 250, optionally composed of a rubber material for waterproofing purposes.
  • Housing 250 has a protrusion forming an air vent channel 230 that matches the shape of protrusion 22 of toe cap 20 and is sized to receive protrusion 22 of toe cap 20.
  • protrusion 230 has an extension part 254 that leads to a heat egress port 232. Heat egress port 232 is clearly shown in the top view of Fig. 13 .
  • heat egress port 232 may comprise an opening that is covered by a mesh or other breathable fabric to allow heat to escape port 232.
  • air vent channel 230 may be open in the direction of the user's foot or it may be covered by a mesh or other breathable fabric to allow heat to enter channel 230 and exit footwear 210 via heat egress port 232.
  • Footwear 210 may also include a heel counter 260 that has its own heat egress port 262 for allowing heat to escape from heel region 216 of footwear 210. As shown in Figs. 12-13 , heat egress port 262 may extend circumferentially around a majority of heel region 216 of footwear 210 to provide adequate ventilation.
  • Toe cap 20 of footwear 210 provides sufficient safety protection during use, along with ventilation via its channel 23, rubber housing 250 provides additional safety protection in addition to waterproofing characteristics, and heat egress port 262 of heel counter 260 allows for ventilation in heel region 216 of footwear 210.
  • Such ventilation and safety structures provide for improved safety footwear 210 with efficient ventilation to keep a user's foot comfortable during use.
  • footwear 210' is shown in Fig. 14 .
  • Footwear 210' includes one or more side or lateral vents 258' positioned on one or both sides of air vent channel 230' of housing 250' (e.g., to provide for lateral air ventilation out of channel 230').
  • Footwear 210' may also include a heat egress port 232' or it optionally may be closed and not include such a port, as shown in Fig. 14 .
  • footwear 210' is the same as footwear 210, and thus, like reference numerals refer to like elements in this embodiment (although a prime designation is added to the reference numerals of Fig. 14 ).
  • footwear 210' may include all of the features of footwear 210 of the previous embodiment, although not specifically discussed herein.
  • Fig. 15 depicts footwear 310, according to yet another embodiment of the invention. Due to the similarities between the previous variants of footwear and footwear 310, like reference numerals refer to like elements in this embodiment (although in the 300-series of numbers), and predominantly the differences between each footwear embodiment are discussed below.
  • Footwear 310 is different from previous embodiments in that, although toe cap 20 is used as in all embodiments, the ventilation structure of footwear 310 is incorporated into a metatarsal guard 370 component.
