Definitions

  • the invention relates to a shoe with a rigid sole having a tread, in particular a ski shoe. If shoe is mentioned below, this is understood in a broader sense.
  • the term shoe in the sense of the invention relates to footwear in general, that is to say also boots.
  • safety bindings are provided to prevent leg fractures.
  • the function of the safety binding is significantly influenced by the nature of the shoe sole. With a dimensionally stable and flat shoe sole, a constant, play-free fit between the ski boot and the safety binding is achieved, which ensures that it functions properly. It is also important that the tread on the ski surface has a low coefficient of friction, so that excessive friction between the ski surface and the sole of the shoe does not impair the release of the safety binding.
  • the ski boots are made of an inelastic material that is usually made of plastic.
  • the desired shape retention of the shoe sole is achieved with this material. This fulfills the requirements for a play-free connection between the shoe and the safety binding.
  • this material especially with smooth treads, the friction between the shoe and the ski can be kept low.
  • Both CH-B-593 642 and CH-B-610 499 describe a device for easy and safe walking in shoes or boots with rigid soles.
  • the device consists of a part which can be removably attached to the sole and which forms an elevation on the underside of the sole. Through this elevation, an at least approximately anatomical movement is achieved when walking.
  • the respective device is removed before the skis are strapped on and located somewhere, e.g. in a pocket of a ski jacket.
  • Providing a pair of devices is not only inconvenient, it also creates a hazard that can result in injury in the event of a fall. There is also the risk of forgetting to take the devices with you before a ski trip. Finally, there is a risk that these devices will be lost.
  • this object is achieved in that at least one element is provided, which can be moved from a rest position in a recess in the sole to a working position in which it protrudes over the tread. After moving the element into the working position, walking is much easier. By returning the element to the rest position, a normal connection of the boot with the safety ski binding is made possible without the frictional conditions being adversely affected in any way. This ensures that the safety binding is triggered safely. Since, according to the invention, no separate additional devices are required in principle, there is no need to place such additional devices anywhere when not in use to accommodate in a jacket pocket. There is also no need to fear that additional equipment will be forgotten or lost. All of this contributes to safety and accident prevention before, during and after skiing.
  • the shoe is characterized in that at least one elastic, preferably inflatable element, which can be pressurized, is embedded in the sole and that a pressure relief valve is installed, the inflatable element and the pressure relief valve being connected to one another by a line embedded in the sole .
  • a pump can be attached in the middle area of the sole or on the ski boot. It can also be carried as a separate pump so that the elements in both shoes can be inflated with a single pump.
  • the element is pivotably mounted in the sole and can be folded from the rest position into the working position and back again.
  • This embodiment is inexpensive to manufacture.
  • a further embodiment of the invention provides that the element can be shifted from the rest position into the working position and back again by means of a curve.
  • This embodiment is also relatively cheap to manufacture.
  • the curve is particularly advantageous as it is self-locking. This has the advantage that no special locking devices are required to hold the element in the selected position.
  • an actuating device for example a cable or slide, for moving the element or elements.
  • This enables convenient actuation, for example by providing an actuating member at the front and / or rear of the shoe above the sole of the shoe. It is then sufficient to actuate an actuator to move all the elements at the same time.
  • Another embodiment of the invention provides that a hydraulic pump is accommodated in the sole, with which hydraulic fluid can be pumped from a reservoir to at least one element, that a first valve is provided to prevent backflow, and that a second valve is provided to allow backflow.
  • a combined valve which prevents the backflow in the working position and which allows the backflow to return to the rest position of the element.
  • the use of the hydraulic system described has the advantage that it is very well suited for series production.
  • At least one element is expediently arranged both in the heel area and in the toe area of the shoe. This significantly improves the stability. It is particularly advantageous if two elements are arranged at a distance from each other in the heel area and in the toe area. This results in a good four-point support with high stability.
  • FIG. 1 shows a ski boot, in the sole 12 of which an inflatable element 1 is installed in the toe region, an inflatable element 2 under the heel and a pump element 3 in the middle.
  • the elements 1 and 2 are advantageously of the same design. Two elements 1 and 2 are expediently arranged next to one another at a distance from one another. But it would also be possible to arrange a single element 1 approximately in the middle of the sole 12 and the pump element 3 e.g. to be placed in front of or behind this element.
  • FIG 2 shows in section the bellows-like membrane 30, which is the termination for the housing 31 of the pump element 3 and Figure 3 shows the bellows-like membrane 10 for the inflatable elements 1, 2, both in the idle state.
  • the membranes 10, 30 consist of rubber or a rubber-elastic plastic.
  • the bellows-like membrane 10 are held in a rigid housing 11 embedded in the sole 12, for which the membrane 10 forms an airtight seal to the outside.
  • the housings 11 are held interchangeably in the sole 12.
  • the diaphragm 10 forms the bottom, the end for the housing 11 on the outside.
  • a pressure relief valve 4 is installed in the front of the sole 12.
  • this is a ball valve with a pin 41 slightly protruding at the front. This arrangement has the advantage that when the ski is tied into the binding, the pin 41 is automatically pressed inwards and the pressure is released from the inflatable elements.
  • a suction valve in the form of a diaphragm valve 32 and a non-return ball valve 33 are installed in the housing 31 of the pump element 3.
  • the check valve is connected to a line 5 which is laid in the sole 12 and connects the pump element 3 to the inflatable elements 1 and 2 and to the pressure relief valve 4.
  • the protruding membrane 30 When running, the protruding membrane 30 is pressed in and presses air through the line 5 into the inflatable elements 1 and 2. This is repeated with each step and the membrane 10 comes out until it protrudes approximately the same distance as the pump membrane 30. One then runs with air suspension on the inflatable membranes 1 and 2. The pump automatically becomes ineffective and a certain pressure is reached, namely when a pressure has been reached at which the suction volume has been displaced into the "lost space" of the pump. In order to reduce this lost space, that is to say to increase the maximum achievable pressure, a filler 35 is attached to the inside of the bellows-shaped membrane 30.
  • a pump 9 can be attached to the front or elsewhere on the ski boot, as indicated by broken lines in FIG. 1.
  • the pump 9 thus arranged can be operated with a ski pole.
  • FIG. 4 shows a variant of a ski boot that is simpler in construction than that of FIG. 1, in that a separate pump 9 'is used here to inflate the inflatable elements.
  • FIG. 5 A part of such a pump 9 'is shown in FIG. 5. It can be constructed very simply, for example like a bicycle pump. However, embodiments that do not require any auxiliary devices are preferred.
  • a non-return inlet valve 8 is provided on the rear of the ski boot, as is a pressure release valve 4 in the front of the sole 12 in the embodiment according to FIG. 1.
  • a bicycle valve could also be installed. In this case, a separate pressure relief valve could even be omitted because the pressure can also be released through the same valve.
  • the inflatable elements 6, 7 are embedded in the sole at the front and rear as previously described. Instead of bellows-like membranes, flat membranes 10 'are used here. This embodiment is therefore simpler than that according to FIG. 1 and therefore also cheaper to manufacture.
  • valve 4 in the front of the sole 12 is designed such that it can be used both as a filling and as a drain valve.
  • the inflatable elements could then be removed using a small pressurized gas container, e.g. a carbon dioxide ampoule.
  • the filling valve 8 can then be omitted.
  • elements 23 are mounted in recesses 22 in the front and rear in pivotable manner about an axis 24. As shown by arrows, the elements 23 can be folded over from the rest position in the recesses 22 into the working position. An element 23 is thus shown in the working position.
  • the elements 23 are advantageously made of plastic and have a structure 25 as anti-slip.
  • locking means 26, 27, for example permanent magnets can be provided, which are accommodated in the sole 12 or in the element 23.
  • Four elements 23 are advantageously arranged in the sole 12, namely two elements at a distance from one another in the heel area and in the toe area.
  • each element 23 is also provided, ie again two in the heel area and two in the toe area.
  • a curve 28 is provided, in which a slide 29 engages.
  • a slot 28 in element 23 can serve as a curve, for example. If the slider 29 is moved from the left position to the right position, the element 23 is moved to the position shown in dashed lines.
  • the slope of the curve 28 is chosen such that it is self-locking. If pressure is exerted on an element 23 in the working position, the self-locking nature of the curve 28 prevents the element 23 from sliding back into the rest position.
  • the actuating device 45 is used to move the elements 23 from one position to the other.
  • This consists, for example, of a cable or slide to which the sliders 29 are attached.
  • a sliding piece can be formed at the front and at the rear. If the actuating device 45 is thus pulled on the ring 47, the elements 23 are moved outwards. The actuating elements 23 can be moved inwards again by pulling on the ring 48.
  • a hydraulic pump 51 is housed in the sole 2.
  • This pump 51 can basically be of the same design as that of FIG. 1, so that reference can be made to the description there.
  • the pump 51 is connected to the reservoir 53 via an inlet valve 52.
  • An outlet valve 54 connects the pump 51 via the line 55 to the cylinders 57, which serve to actuate the elements 23.
  • These can be in the form of pistons.
  • FIG. 9 shows a construction which makes it possible to accommodate elements 23 in the form of hydraulic or pneumatic pistons in a relatively thin sole 12 in such a way that they function properly.
  • Element 23 has e.g. cylindrical recess 61, in which a preferably hollow pin 63 engages. This pin 63 serves as a guide and prevents the element 23 from tilting.
  • a return spring 65 can engage a flange 67 in order to move the element into the rest position when no pressure acts on the piston 23.
  • the reference number 55 in turn designates the line which connects the pump 51 (FIG. 8) or 3 (FIG. 1) to the cylinder space 57.
  • FIG. 10 shows a section through an advantageous pump construction for a pneumatic or hydraulic pump 4 or 51.
  • the reference number 30 in turn designates the diaphragm.
  • the housing consists of the frame 71 and the cover 73.
  • a first group of fingers with noses 75 is formed on the frame 71. If, after inserting the membrane 30, the cover 73 is pressed into the frame 71, the lugs 75 engage on the cover 73 and thereby seal the space 77.
  • a second group of fingers 78 with lugs 79 is used to insert the pump 3, 51 into the sole 12.
  • the construction shown in FIG. 10 can also be used for the inflatable elements 1, 2.
