Abstract
A sports shoe (1) is provided with air chambers underneath a comparatively rigid outer shell (2) such that pressure in these air chambers, i.e., the compression on the foot, can be adjusted by a pump system (5, 6). The design of the pump system is simple, easy to manufacture, compact and operationally reliable due to the valves (14, 15) of the pump system being enclosed in a common housing part (13) separated by a partition (20) from the membrane pump chamber (11). The valves (14, 15) are mounted coaxially in tandem sequence. The evacuating valve (15) can also serve as the pump suction valve and is provided at an end (37) with a manually displaceable stem which, during evacuation of the air chamber, wil make contact with the valve stem (b 32) of the pump pressure valve (14).
Claims22
A sports shoe, having an inflatable air chamber, enclosed underneath an outer shell of the shoe and disposed in the form of a cushion to be adjacent a foot of the shoe wearer, and a pump system connected to the air chamber that includes a membrane pump chamber and a valve system with a pump pressure valve followed in the direction of venting therefrom by an evacuation valve, said pump system being set into a receiving aperture provided therefor in the outer shell of the shoe, characterized in that:
- said valves of the valve system are enclosed in a common housing part mounted next to the membrane pump chamber.
