Definitions

  • the invention relates to a sports shoe according to the preamble of claim 1.
  • the stuffer box is essentially rectangular in vertical cross section.
  • the stuffer box is delimited at the top by the top layer and at the bottom by the profile layer of the sole.
  • the inlet opening and the outlet opening are arranged in the vertical vertical wall areas just below the top layer.
  • the object of the invention is therefore to provide a sports shoe of the type mentioned. in which there is an improved effect of the loading device while minimizing the dead space of the stuffer box.
  • the sports shoe according to the invention solving this problem, has the characterizing features of patent claim 1.
  • the dead space is minimized when the stuffer box is compressed, since the chamber roof clings to the bottom of the stuffer box.
  • a pneumatic overpressure corresponding to the power surge that occurs can thereby be generated.
  • With a reduced stroke movement is a improved chamber inflation achieved.
  • the volume of the stuffer box can be reduced, which improves the behavior of the sports shoe when worn.
  • the vertical cross section of the stuffer box decreases towards the edge thereof, the inlet opening and outlet opening are arranged in the region of the center, so that they are not blocked by stuffer box walls even when the stuffer box is strongly compressed.
  • the loading device is arranged with the inlet opening and the outlet opening approximately at the "zenith" of the crowning of the stressful foot area, which is usually the heel.
  • the inlet valve is arranged close to the inlet opening in order to avoid a channel between the inlet opening and the inlet valve and the outlet valve is arranged close to the outlet opening and also the inlet valve and the outlet valve are arranged in the middle region of the stuffer box, any dead space between the opening and the valve is avoided . This is possible because there is enough space available for the valves due to the extremely flat stuffer box.
  • valve parts When realizing the inlet valve and the outlet valve, rigid parts and firm connections of valve parts with other parts of the loading device with the sole should be avoided, since this causes damage in connection with the elasticity of the sole material.
  • the valve parts should also be adapted to the other parts of the sole and the loading device because of the material shrinkage.
  • the proposed valves are exceptionally flat and therefore particularly suitable for arrangement above and below the stowage space.
  • the valve disc is airtight from plastic.
  • a foam block that is resilient when compressed is an air-permeable spring element and serves as a compression spring.
  • a central area of the valve lamella z. B. covers the inlet opening when loaded by the foot. The return movement of the Valve lamella takes place due to its own elasticity supported by the resilience of the loading device.
  • the openings are usually designed as fine perforations.
  • the manufacture of the chamber body and chamber roof is more complex. This can be compensated for by the unit.
  • the assembly also simplifies valve integration. It is now possible to manufacture the chamber body and chamber roof together from a plastic which is somewhat different from the plastic of the other sole, especially since the chamber roof has a function similar to that of a pump membrane and is somewhat stretchable.
  • the loading device or parts thereof exist, for. B. from a silicone rubber.
  • the stuffer box trough does not necessarily have to be circular in the horizontal cross section, but it is usually. It is particularly expedient and advantageous if the stuffer box trough has a ratio of diameter to height of 5: 1 to 12: 1, which illustrates the flatness of the stuffer box of the sports shoe according to the invention.
  • the central height is 5 - 7 mm and the largest diameter, e.g. B. at the top of the chamber roof, at 27 - 37 mm.
  • the loading device is placed on it.
  • the dimensions of the loading device or sports shoe are adapted to the average values of the normal user.
  • the loading device according to the invention also represents an improved support for the heel because of the stuffer box trough. There is always a slight discharge of the sole chambers, since these are not completely tight to the outside.
  • a particularly expedient and advantageous embodiment of the invention is when the inlet opening is arranged laterally next to the outlet opening and the valve lamella, the inlet valve and the valve disk of the outlet valve are arranged on opposite sides of the same chamber housing area. This simplifies the design of the charging device, the inlet valve is arranged more protected and the lateral supply of air is simplified.
  • the 1 has an upper shoe (1), the sole part (2) of which is permeable to air in a manner not shown in the heel area.
  • the sole part is e.g. Crossed slits in the heel area to achieve air permeability and compliance.
  • a foot is housed in the upper shoe (1), the heel (3) of which is indicated and which is convex at the bottom.
  • the upper shoe (1) is attached to a sole (4), the heel (5) of which is shown in Fig. 1 and is located under the heel (3).
  • the sole (4) has a profile layer (6) at the bottom, a core layer (7) above and an upper layer (8) on top, which is much thinner than the core layer (7).
  • the profit situation (6) consists of a relatively solid, less compressible, full plastic.
  • the core layer (7) and the top layer (8) consist of the same material as one another, namely of an elastically compressible, foamed plastic.
  • the sole or the sum of the core layer and the top layer is thicker in the sales area than in the rest of the sole.
  • the upper layer (8) has in the area of the heel (5) under the heel (3) and the air-permeable area of the sole part (2) as perforations (9) which are each arranged at a horizontal distance from a center.
  • a circular cross-section (10) is provided, which is closed towards the bottom and is open towards the top layer (8).
  • the recess (10) merges into a small recess (11) in the center at the bottom and receives an inserted structural unit (12) on which the top layer (8) lies loosely without being glued.
  • the assembly (12) comprises a chamber body (13), a chamber roof (14) and a valve lamella (15), which is also full in the middle, which are each made of silicone rubber, the valve lamella resting tightly and loosely on the chamber roof (14) and being glued to the chamber roof (14) along the peripheral edge (19) .
  • the chamber body (13) and the chamber roof (14) form a chamber housing, are made in one piece and delimit a stuffer box (16) which is designed like a half lens and here is curved downwards.
  • the chamber roof (14), which represents a type of pump membrane, has an inlet opening (17) in the center, and below this the chamber body forms an outlet opening (18) in the center.
  • the chamber roof (14) forms on the side facing the valve lamella (15) small, elastically compressible knobs (20) and also one of the two opposite surfaces of the stuffer box (16) is provided with such knobs (20), the knobs being integral with the chamber cover or the chamber body.
  • the outlet opening (18) merges into a cavity (21), which is accommodated in the chamber body (13) and receives a valve disk (22) arranged under the outlet opening, which from below is supported by a spring block (23) made of foam is acted upon.
  • the cavity (21) is connected at the bottom via an opening (24) to the small recess (11).
  • the inlet opening (17) is blocked by pressure on the valve lamella (15) and the stuffer box (16) is compressed.
  • the valve disc (22) is pressed down and air flows through the outlet opening (18) to the small recess (11).
  • the valve disc (22) closes the outlet opening (18) and air is sucked into the stuffer box (16) via the openings (9), the openings (25) of the valve lamella (15) and the central inlet opening (17).
  • the elastic restoring force of the chamber body, chamber roof and valve lamella comes into effect when the load is released.
  • the recess (10) provided with the small recess (11) is provided in the core layer (7), specifically in the area of the shoulder (5).
  • the loading device is also designed as a structural unit (12).
  • the chamber roof (14) is completely full, that is to say without a breakthrough, and there are 2 inlet openings (17) laterally next to the central outlet opening (18) in the center region of the trough close to the outlet opening. Every inlet opening is located at the inner end of a channel (28) leading radially outwards in the chamber body (13).
  • the valve lamella (15) forms the curved bottom of the stuffer box (16) and is loose from the center radially outwards to a dashed circle (29) from the rest of the chamber body. It has an opening (30) above the outlet opening (18) and has a radially increasing thickness. Between the opening (30) and the inlet openings (17) there is in each case an area in which the valve lamella (15) lies sealingly on the valve body (13).
  • valve lamella (15) When the loading device relaxes and the stuffer box (16) sucks in air, the valve lamella (15) lifts off, so that air can flow through the channel (28) and the opening (30) into the stuffer box (16).
  • the valve lamella (15) is very thin where it has a sealing function and where it covers the channel (28) it is thicker and therefore firmer.
  • valve lamella in the sealing area is pressed against the chamber body, whereby the connection between the stuffer box and the channel (28) is blocked.
  • the cavity (21) is shut off at the bottom by a perforated membrane (31) and the valve disc works without a special compression spring.
