Field of the Invention
[0001] The present invention relates to a shoe with hygienic device, more particularly to
a shoe with heel, which has ventilation device at its sole.
Description of the Prior Art
[0002] A
Chinese Patent No.ZL00242027.9 disclosed a kind of ventilated shoe, it has a ventilated device operated by walking.
The air chamber of the ventilated device is set on the heel of the shoe, on its sole
there are some vent-slots, an air intake check valve is set between the air chamber
and the gathering-slot where the vent-slots join with each other. Meanwhile, the air
chamber is joined with the air exhaust check valve, and the air exhaust check valve
is opened to atmosphere. This kind of ventilation device is more suitable for the
shoe with slope heel, but it is difficult for the shoe with heel as there is an obvious
90°step between the heel and the sole piece. The step causes that the distance between
the intake end of the air intake check valve and the gathering-slot where the vent-slots
join with each other becomes very short. Under the limit of the thickness of the sole
piece, the sole piece is easy to be broken at that place if the air-gathering pipeline
is too long. Therefore, the air must pass longer vent-slots and then be gathered in
the air-gathering pipeline. It directly influences the inhaling ability of the ventilated
device, the inhaling is not concentrative, and the inhaling power is weak, the effect
of ventilating is reduced. Furthermore, under the interference of the air exhaust
check valve, the advantage brought from the concave space on the heel can't be used,
to enlarge the air chamber for improving the ventilation quantity is restricted. Moreover,
the air chamber connects the air exhaust check valve by direct insert, this kind of
connection is easy to loosen, causes the reduce of ventilating.
Summary of the invention
[0003] It is an object of the present invention to provide a kind of ventilated shoe with
heel, which is capable to increase the quantity of the ventilation and to improve
the quality of the ventilation.
[0004] To achieve this object, the present invention adapts the following technical solution:
a kind of ventilated shoe with heel, includes several vent-slots on the sole piece,
an air intake check valve, an air exhaust check valve and an air chamber set in the
concave space on the heel, characterized in that the vent-slots on the sole piece
gather together near the center of a toes transverse line (in other words, a toes
circumference line, meaning a line joining the sideways outstanding point of the thumb-toe
and the sideways outstanding point of the little-toe) on the sole piece, and a convex
air-gathering pipeline is disposed between the gather point and the air intake check
valve. Due to the length of the air-gather pipeline is increased, and the entrance
of the air-gather pipeline directly extends to the center of toes transverse line,
then, the collected air from the shoe chamber passing through the vent-slots can be
congregated in a relatively short distance; therefore, the air chamber' s inhaling
force is centralized and increased, and thus the ventilation quantity and quality
both are improved.

Detailed description of the preferred embodiment
[0006] To enable a further understanding of the innovative and technological content of
the invention herein, refer to the detailed description of the invention and the accompanying
drawings below:
[0007] The main components of the ventilated shoe with heel of this embodiment are similar
to a regular shoe with heel. In this embodiment, several vent-slots set on the inner-sole
(middle-sole and inner-cushion) are generally the same as the disclosure of the
Chinese Patent No. ZL00242027.9, and the main differences are on the structure of the sole piece (13).
[0008] As shown in FIG 1, the sole piece includes several vent-slots (1), an air intake
check valve (12) and an air exhaust check valve (3). The vent-slots (1) on the sole
piece gather together near the center of toes transverse line (20) on the sole piece.
A convex air-gather pipeline (2) is disposed between the gather point and the air
intake check valve (as shown in FIG 3) . As shown in FIG 2, the outer surface (14)
of the convex air-gather pipeline (2) is connected smoothly with the sole piece through
approach ramp, in order to ensure the balance of the interface between the sole piece
and the ground and not to infect the use of the shoe. A latex pipe (11) is sleeved
on the outside of the pipe connection between the air intake check valve (12) and
the air chamber in order to prevent air leaking. The convex-shaped air chamber (9)
is set in the concave space on the heel, and the annular surface (10) of the air chamber
(9) and the annular surface (15) of the heel are on a same plane. Thus, the height
of the raised surface of the air chamber compare with the plane is ensured. For the
ventilated shoe with short heel it still ensures the height of the air chamber, and
still keeps the compression capability of the air chamber; for the ventilated shoe
with high heel the quantity and quality of the ventilation are improved. Furthermore,
the alignment of the annular surface of the air chamber and the annular surface of
the heel forms a platform to stick with the middle piece, based with having enough
supporting area between the sole and middle piece, the concave space of the heel gives
a maximal possible space for the air chamber, therefore, the volume of the air chamber
is increased much..
[0009] As shown in FIG 1, the exhaust port (7) and intake port (8) parallel with each other,
and a convex L-shaped installation groove (4) is set on the sole piece between the
exhaust port (7) and the outside of sole piece (as shown in FIG 3). The exhaust port
is connected to the exhaust valve (3) through a soft pipe (5) mounted on the L-shaped
installation groove, and the exhaust valve (3) is opened to the atmosphere. Because
the exhaust valve is apart from the heel, the concave space of the heel can gain a
maximal space for the air chamber. The connection between the exhaust port (7) and
the exhaust valve (3) is a soft pipe (5) which wraps both of them, and as the interface
is soft connection, there is no air leak or connection loosening after long time usage,
therefore, the effect of the ventilation is good. In addition, there is a moveable
soft underlay (6) inside the soft pipe (5) to support the soft pipe (5) through when
it is bended.
[0010] In summarize, the present invention has the following advantages compared with the
prior arts:
- 1. It increases the quantity and improves quality of the ventilation of the ventilated
shoe with heel.
- 2. There is no air leak problem after long time using, it ensures the better effect
