Definitions
- the present invention relates to an air pump assembly for ventilative footwear, and particularly, to an air pump assembly for ventilative footwear, in which the air pump assembly is mounted onto a heel portion of an outsole, so that external air is forcibly introduced into an interior of a shoe when walking, thereby cleaning the interior of the shoe and providing a pedestrian with a cushion function.
- an object of the present invention is to solve the problems involved in the prior art and to provide an air pump assembly for ventilative footwear, in which a resilient ring is provided in a center portion of an elastic cover to form a concave portion, and upon pumping of the air pump assembly the elastic cover is inwardly retracted and then restored to increase a pumping and damping efficiency.
- an air pump assembly for ventilative footwear, the air pump assembly comprising: a base plate with check valves for regulating air flow mounted on both sides; an upper rigid plate; a compression spring interposed between the base plate and the upper rigid plate; an elastic cover covering the upper rigid plate, with a border thereof being airtightly hot-melted onto the base plate; and a resilient ring interposed between the base plate and the rigid plate, so that a middle portion of the elastic cover is pulled toward a center axis of the resilient ring to form a concave bending portion.
- Fig. 1 is a perspective view illustrating an air pump assembly for ventilative footwear according to one preferred embodiment of the present invention.
- Fig. 2 is a cross sectional view taken along a line A- A in Fig. 1.
- Figs. 3a and 3b are perspective views illustrating alternative embodiments of a resilient ring according to present invention.
- Fig. 4 is a cross sectional view illustrating the operation of an air pump assembly for ventilative footwear according to the present invention.
- Fig. 1 is a perspective view illustrating an air pump assembly for ventilative footwear according to one preferred embodiment of the present invention
- Fig. 2 is a cross sectional view taken along a line A- A in Fig. 1.
- the air pump assembly comprises a base plate 14 with a pair of rear and front check valves for regulating air flow 22a and 22b mounted on both sides, an upper rigid plate 16, a truncated cone-type compression spring 18 interposed between the base plate 14 and the upper rigid plate 16, and an elastic cover 12 made of a resin having a superior elastic force and covering the upper rigid plate 16, with a border thereof being airtightly hot-melted onto the base plate 14.
- a resilient ring 20 is interposed between the base plate 14 and the rigid plate 16, so that a middle portion of the elastic cover 12 is pulled toward a center axis of the resilient ring to form a concave bending portion 13.
- the rear check valve 22a is connected to an intake tube 24 communicating with the atmosphere, while the front check valve 22b is connected to a supply tube 26 communicating with the interior of the shoe.
- the resilient ring 20 is closely contacted with an outer edge of the middle portion of the elastic cover 12, and applies a certain level of elastic force to the middle portion.
- the resilient ring 20 is made of a rubber or synthetic resin having a superior elastic force, and has a circular shape when seen from a top.
- Each of the base plate 14 and rigid plate 16 has a fixing portion 19 for rigidly fixing the compression spring 18, the fixing portion 19 protruded from an inner surface of the base plate and rigid plate in a shape of ring.
- Figs. 3a and 3b are perspective views illustrating alternative embodiments of a resilient ring according to present invention.
- the resilient ring 20 shown in the above embodiment may be replaced with a coil spring 20a having an excellent elastic force as shown in Fig. 3a, or a hollow pipe 20b made of same material as that of the coil spring 20a as shown in Fig. 3b.
- the air pump assembly for ventilative footwear functions as follows:
- Fig. 4 is a cross sectional view illustrating the operation of an air pump assembly for ventilative footwear according to the present invention. If the pressure is applied to the air pump assembly 10 upon walking, the rigid plate 16 is lowered, and thus the compression spring 18 is compressed, as shown in Fig. 4. The elastic cover 12 is retracted to discharge the air from the air pump assembly 10 to the interior of the shoe via the check valve 22b and the supply tube 26. Alternatively, the air flow may be adversely converted by installing the check valves 22a and 22b to discharge the moisture and air from the shoe to the external. At that time, the compression of the elastic cover 12 causes the resilient ring 20 to pull the bending portion 13 inwardly. The bending portion 13 is smoothly bent along the resilient ring 20.
- the rigid plate 16 is raised by the compression spring 18, and the elastic cover 12 is naturally restored, so that the air pump assembly 10 is filled with the external air through the intake tube 24 and the check valve 22a.
- the inwardly retraction of the elastic cover 12 increases a discharging amount of the air from the air pump assembly.
- the flow rate of the air is maximized, and a fresh air is sufficiently supplied to the interior of the shoe by the air pump assembly, thereby preventing the offensive odor and the dermatophytosis.
- the air pump assembly increases the sucking and supplying efficiency of the air, there is a damping effect of reducing a shocking force and thus fatigue of the pedestrian.
