Abstract

Apparatus (10) for ventilating footwear having an air chamber (20) formed as part of the sole or inner sole of an item of footwear. An inlet valve (18) and an outlet valve (26) are provided to control passage of air to and from the air chamber (20). An inlet (12) communicates with the inlet valve (18) and an outlet comprising at least one outlet aperture (32) communicates with the outlet valve (26). The air chamber (20) comprises a variable volume enclosing one or more resilient members (24) such that a substantial portion of the air chamber (20) is left unoccupied. The apparatus (10) is configured such that the volume of the air chamber (20) is varied by periodic placement of weight on the air chamber (20) so as to cause the variable volume to expand and contract. This causes air to be drawn through the inlet (12) and pumped through the outlet aperture (32) and distributed around the foot of the wearer.

Description

TITLE "APPARATUS FOR VENTILATING FOOTWEAR" DESCRIPTION The present invention relates to an apparatus for ventilating footwear, such an apparatus being either built in to the footwear, or provided as an attachment or insert for insertion into footwear.
FIELD OF THE INVENTION The apparatus of the present invention allows air to flow in the footwear whilst being worn by a person. The provision of this flow of air adds to the comfort of the wearer.
SUMMARY OF THE INVENTION In accordance with one aspect of the present invention there is provided an apparatus for ventilating footwear comprising an air chamber formed as part of the sole or inner sole of an item of footwear, an inlet valve means and an outlet valve means to control passage of air to and from the air chamber, an inlet means communicating with the inlet valve means, an outlet means communicating with the outlet valve means, the outlet means comprising at least one outlet aperture, the air chamber further comprising a variable volume enclosing one or more resilient members, such that a substantial portion of the air chamber is left unoccupied, the apparatus being configured such that the volume of the chamber is varied by periodic placement of weight on the air chamber so as to cause the variable volume to expand and contract thus causing air to be drawn through the inlet means and pumped through the outlet means and distributed around the foot.
BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a sectional side view of an apparatus in accordance with the present invention; Figure 2 is a sectional plan view of the apparatus of Figure 1;
Figure 3 is a sectional view of a valve means for use in the apparatus of the Figures 1 and 2; and Figure 4 is a side view along line 4-4 of the valve means of Figure 3.
DESCRIPTION OF THE INVENTION Shown in Figures 1 and 2 is an apparatus 10 for ventilating footwear. The apparatus 10 comprises an air inlet means 12, which is typically a flexible tube. The apparatus 10 further comprises an upper layer 14 spaced from a lower layer 16. The upper layer 14 further comprises an additional layer 15 overlaying the portion of the layer 14 containing an air chamber, to be described hereinafter. It is envisaged that the layer 15 is to be composed of a relatively soft layer to give it some resilience. The layer 14 may typically be composed of a foam rubber to . produce a cushioning effect for the foot. The layer 16 may be composed of a relatively strong material, of the type used for shoe soles. This would give the layer 16 a measure of abrasion resistance. The inlet means 12 is in communication with an inlet valve means 18 located between the layers 14 and 16 which in turn communicates with a chamber 20 also located between the layers 14 and 16. The air chamber 20 comprises upper and lower seating plates 22 composed of a relatively stiff material, typically hard plastics, each located adjacent a respective layer 14 and 16. The air chamber 20 further comprises a piston member
23 preferably attached to a seating plate 22. It is preferred that the piston member 23 be composed of a non-porous resilient material. Additionally, the piston member 23 has a plurality of transverse apertures 25, preferably extending therethrough.
Between the plates 22 are located a plurality of resilient members 24 typically coil springs, the resilient members 24 being disposed so as to resiliently space the seating plates 22. Further, each resilient member 24 is partially contained within one of the apertures 25. The apertures 25 serve to locate the resilient members 24 and prevent buckling of the same.
The resilient members 24 are disposed in the air chamber 20 such that a substantial portion of the air chamber 20 is left unoccupied.
The air chamber 20 is in communication with an outlet valve means 26 located between the layers 14 and 16. The outlet valve means 26 in turn communicates with an outlet duct 28 via a conduit 30.
The conduit 30 is located between the layers 14 and 16, preferably adjacent the layer 16. The outlet duct 28 comprises a plurality of apertures 32 arranged to discharge air through the layer 14, preferably near the toe region of the footwear.
It is preferred, in the present embodiment, that the air chamber 20 be located in the heel region of the footwear, though other locations may be used in accordance with the present invention.
Shown in Figures 3 and 4 of the accompanying drawings is a valve means 18, 26 envisaged for use with the apparatus of the present invention. The valve means 18, 26 comprises a body 40 having an inlet 42, an outlet 44 and a chamber 46 therebetween.
Located within the chamber 46 is a moveable member 48. The' member 48 has a first end 50 shaped to sealingly fit into the inlet 42. The member 48 also has a second end 52 shaped so as to not sealingly fit into the outlet 44. Preferably, the outlet 14 further comprises a plurality of curved arms 45 extending partially across the outlet 44. The member 48 is preferably composed of a light material so as to be moved by relatively low air velocities.
Thus, the valve means 18 r 26 permit air flow in one direction only from the inlet 42 to the outlet 44. Air flow in the reverse direction causes the member 48 to sealingly engage with the inlet 42. In use the apparatus 10, of the present invention, is either integrally formed with or inserted into an item of footwear (not shown) such that the lower surface 16 is adjacent the sole of the item of footwear. The wearer of the footwear places his weight on the upper surface 14. This urges the upper surface 14 towards the lower surface 16. The displacement continues until either the piston member 23 contacts the seating plate 22 adjacent the lower surface 16, or the weight of the wearer is balanced by the compression of the resilient members 24. When the resilient members 24 comprise coil springs the seating plates 22 being of a relatively stiff material, prevent the coil springs from penetrating into the foot of the wearer or through the lower surface 16. This displacement causes the volume of the chamber 20 to decrease. Air is then expelled through the outlet valve means 26 since air cannot flow out of the inlet valve means 18 due to the one way flow characteristics described hereinbefore. The air travels along the conduit 30 to the outlet duct 28 where the air is discharged at relatively high velocity through the apertures 32. In such a manner, fresh air is introduced into the toe region of the footwear. The fresh air cools and ventilates the foot of the wearer as well as removing undesirable odours.
The wearer then removes his weight from the upper surface
14.
The resilient members 24 urge the upper surface 14 away from the lower surface 16. This causes the volume of the chamber 20 to increase.
Air is then admitted to the chamber 20 via the inlet means 12 and the inlet valve 18. Air cannot be drawn into the chamber 20 through the outlet valve means 26 due to the one way flow characteristics of the valve means 18 and 26 described hereinbefore.
A substantial portion of the air chamber 20 is available as a working volume since the only parts located therein are the resilient members 24. This enables substantially the entire volume of the air chamber 20 to be available for admission and expulsion of air therefrom. The apparatus of the present invention provides a compact and efficient means of ventilating, and is particularly applicable to sports shoes. Modifications and variations such as would be apparent to a skilled addressee and deemed within the scope of the present invention.
