Definitions
- the present invention relates to a street shoe that has an active pumping element to promote the liner atmosphere to the outside, wherein the conveyor element is activated by the load at every step.
- Developments in recent years in the field of street shoes have this led that increasingly used glued sandwich structures as upper materials be and the shaft area of the shoe is padded so that it hugs the foot.
- polyurethane elastomers due to the favorable processing and Usage properties used as sole materials polyurethane elastomers.
- Both developments have contributed to that when wearing the shoe excess heat (2 to 3 watts) and sweat (approx. 6 g / h) no longer completely through convection over the shaft area (flexing work) or can be dissipated via diffusion through the upper and sole.
- the subjective one Impression of hot feet intensified.
- the Pump actuation also serves as shock absorption when running and also promotes the liner atmosphere to the outside, taking warmth and moisture be dissipated; see in particular WO 87/03789, GB 2 247 391, WO 93/07774.
- street shoes In contrast to sports shoes, street shoes have harder sole and heel materials with shore hardness between 60 and 70, their compression when walking as a lifting movement for an installed pump is insufficient.
- US-A-5 299 368 discloses a street shoe with a membrane pump integrated in the heel.
- the present invention relates to a street shoe with a heel a Shore hardness of 50 to 80 and a membrane pump integrated in the heel to support the exchange of moisture between the inside of the shoe and environment, with the horizontal cross-sectional area of that from paragraph outstanding diaphragm pump piston between 1 and 3% of the horizontal Cross-sectional area and the stroke of the diaphragm piston between 1 and is 3 mm.
- the diaphragm pump can be arranged in the paragraph so that the Diaphragm pump piston protrudes downwards (i.e. on the street side) from the heel or protrudes upwards (towards the heel) from the heel. Preferably protrudes the diaphragm pump piston from the heel up into the space between Sole insert and heel out.
- the diaphragm pump piston is under load in the pump housing integrated in the paragraph while reducing the pump cavity pressed in so that it is flush with the heel surface.
- the horizontal cross-sectional area of the pump cavity is preferably between 3 and 10% of the horizontal sales cross-sectional area, especially that 2 to 5 times the horizontal cross-sectional area of the diaphragm pump piston.
- the delivery capacity of the diaphragm pump should particularly preferably be between 0.1 and 1 ml of shoe inner atmosphere per step, corresponding to one Promotion of 0.7 to 3 g / h moisture when walking.
- the upper material of the shoe according to the invention is preferably an in Shoe industry available upper, especially in the form of glued Sandwich structures, used, the breathability of which is sufficient during of walking to transport 4 to 5 g / h of moisture.
- Such an upper regularly has a sufficiently high level of breathability in order to be able to rest during periods of rest absorb moisture generated in the shoe and convey it to the outside.
- Elastomers such as rubber or PVC, preferably polyurethane
- PVC preferably polyurethane
- the heel and sole are produced in a manner known per se by compression molding a reactive polyurethane mixture, the membrane pump with the corresponding supply and discharge hoses for the air to be conveyed being inserted into the mold before filling with the reactive mixture.
- Figure 1 is an inventive according to the invention schematically in the form of a longitudinal section Street shoe 1 with paragraph 2, sole 3 and the upper 4 shown.
- the diaphragm pump 10 is integrated, the diaphragm reciprocating piston 11th protrudes upwards from the heel and from the not shown sole insert is covered.
- the diaphragm pump 10 preferably sucks into the Shoe sole integrated line 12 air from the toe area of the shoe and promotes this via line 13 along the shaft to the outside.
- the diaphragm pump 10 is behind integrated below in paragraph 2, so that the diaphragm piston 11 on the street side protrudes from the paragraph.
- the diaphragm pump that can be used according to the invention can consist of only five parts, the pump housing 21 with molded Connections to the suction line 12 from the inside of the shoe and the Discharge line 13 via the shaft; one insertable into the housing 21 and Counter 16 fixable via pins 16, which together with corresponding Recesses of the housing 21 forms the valve chambers 14 and 15; one for both valve chambers 14 and 15 common sealing washer 25, which between Housing 21 and counterpart 22 is inserted and under load against on Housing part 21 or the counterpart 22 molded valve seat surfaces 17 and 18 seals or releases the passage via the ring channel 19 or 20; the pump membrane 24 with integrally formed pump piston 11 has a circumferential bead 27 on, both against the pump housing 21 and against the counterpart 22 seals; finally the clamping flange 23, which against a bead 28 of the Housing 21 loaded and the bead 27 against the housing 21 and the counterpart 22 prints.
- Housing 21, counterpart 22 and clamping flange 23 are preferably injection molded parts made of a plastic, in particular polyoxymethylene, which is harder than the sole material.
- the valve membrane 25 preferably consists of a soft elastomer, in particular silicone or a synthetic rubber, like SBR.
- the pump membrane 24 with molded pistons 11 is preferably made made of a thermoplastic elastomer (TPE).
- a return spring can also be located in the pump cavity 26 29 can be provided in the form of a spiral spring ( Figure 6) or in the form a molded elastomer material (Fig. 7) can be formed.
