Definitions

  • the invention relates to a system for automatically putting on/taking off a footwear.
  • footwear any type of footwear item, such as a street shoe, a protection shoe, a sport shoe, etc.
  • the term “shoe” must be understood in its broadest meaning, and can be, for example, a boot.
  • sport shoe also covers any special sport footwear, such as ski boots, skates, etc.
  • Document WO/2017/188833 whose applicant-inventor is identical to that of the present patent application, discloses a footwear embodiment provided with a system for automatically putting on / taking off the footwear, wherein the operation of the system is provided exclusively by actuation with the sole of the user’s foot, the reliability being increased and the outer appearance of the footwear remaining unchanged.
  • WO/2017/188833 comprises:
  • a lower inflatable tank capable of storing pressurized air, fixed inside the footwear in the area of the rear part of the user’s sole;
  • hose provided with a one-way valve (the direction being from the lower inflatable tank into the upper inflatable structure), the hose ensuring the fluid communication between the lower inflatable tank and the upper inflatable structure;
  • an insole hinged to the sole of the footwear which, when actuated by the user’s heel, compresses the lower inflatable tank, causing the air from the lower inflatable tank to enter the upper inflatable structure, increasing its internal pressure and volume, and consequently to press on the user’s foot, thus fixing it within the footwear;
  • a lever operable by means of a button which unlocks the one-way valve and allows air from the upper inflatable structure to return in the lower inflatable tank, thus allowing the release of the user’s foot.
  • said compression force depends somewhat on the shape of the user’s foot (namely the width and the height thereof), reason why some users may feel the footwear too tight on the foot, while other users may feel the footwear insufficiently tight on the foot.
  • the technical problem solved by the present invention is to provide a system for automatically putting on / tacking off a footwear, that ensures an optimal compression force on the user’s foot (irrespective of the foot’s’shape), and implicitlly an optimal tightening.
  • the system for automatically putting on / tacking off a footwear comprises:
  • a movable insole for supporting of the heel rear part of the sole of the user's foot, the movable insole being connected to the fixed insole by means of a joint, and being movable between a first extreme position and a second extreme position; - a deformable tank, fixed between the movable insole and the sole of the footwear,
  • hose non-deformable in terms of volume, capable to ensure the fluid communication between the tank and the chamber;
  • a first one-way valve arranged inside the hose, provided with an unlocking system, and which, when it is not unlocked, allows the fluid to pass through the hose, exclusively from the tank into the chamber, and which when it is unlocked, allows the fluid to pass from the chamber into the tank,
  • an elongated container capable to be in fluid communication with the chamber by means of a first two-way valve, and capable to be in fluid communication with the environment’s atmosphere by means of a second two-way valve, wherein the first two-way valve opens automatically when the pressure within the chamber or within the container exceeds a predetermined threshold value.
  • the unlocking system of the first one-way valve consists either of a lever operable by the user by means of an actuating button, or of a remotely operable electronic system. If the unlocking system consists of a lever and a button, the user may operate the button with his other foot.
  • the joint is provided with a first spring capable of holding the movable insole in its first extreme position when the footwear is not put on by the user.
  • the chamber is in contact, at its upper part, with a rigid portion of the footwear, and at its lower part with a flap fixed by means of a hinge to the rigid portion, at the extremity closer to the tip of the footwear.
  • the hinge is provided with a second spring, that pushes the flap towards the rigid portion of the footwear.
  • the fluid is a liquid and the container is further provided with:
  • the system is further provided with two elastic, deformable primary compartments, fixed inside the footwear, arranged laterally, on either side of the chamber, and in fluid communication with the chamber by means of associated primary pipes that are non- deformable in terms of volume, wherein substantially the entire amount of fluid completely fills the hose, the chamber, the primary pipes and the primary compartments when the movable insole is in its second extreme position wherein it compresses and deforms the tank to the maximum, situation where the primary compartments are elastically deformed by their increase in volume, in the direction towards the inside of the footwear.
  • the system is further provided with at least two elastic, deformable secondary compartments, fixed inside the footwear, arranged laterally, on either side of the chamber, preferably at the heel area of the footwear, each secondary compartment being in fluid communication with the primary compartment situated on the same side, via an associated secondary pipe, wherein substantially the entire amount of fluid completely fills the hose, the chamber, the primary pipes, the primary compartments, the secondary pipes and the secondary compartments when the movable insole is in its second extreme position wherein it compresses and deforms the tank to the maximum, situation where both the primary compartments and the secondary compartments are elastically deformed by their increase in volume, in the direction towards the inside the footwear.
  • Figure 1 shows a first embodiment of the system according to the invention, for automatically putting on/taking off a footwear, comprising:
  • movable insole 3 for supporting the heel rear part of the sole of the user's foot, the movable insole 3 being connected to the fixed insole 1 by means of a joint 4, and being movable between a first extreme position and a second extreme position.
  • joint must be understood in its broadest sense, which can also mean, for example, a hinge, a folding line, etc.
  • non-deformable in terms of volume capable to ensure the fluid communication between the tank 5 and the chamber 6.
  • non-deformable in terms of volume is meant that the inner volume of hose 7 remains substantially constant when a fluid transfer occurs between the tank 5 and the chamber 6.
  • the outer appearance of the hose 7 may vary (for instance, in the direction of its length it can take the shape of a circular arc with a variable radius).
  • Fluid 8 may be a gas (for example air) or a liquid (for example water). Substantially the entire amount of fluid 8 is in the tank 5 when the movable insole 3 is in its first extreme position in contact with the undeformed tank 5. On the other hand, substantially the entire amount of fluid 8 is in the hose 7 and in the chamber 6 when the movable insole 3 is in its second extreme position and compresses and deforms the tank 5 to the maximum.
  • the volume of the tank 5, when full of fluid and in the undeformed state, is greater than the sum of the volumes of the hose 7 and of the undeformed chamber 6.
  • the pressure within the chamber 6 has a clearly higher value compared to the pressure within the chamber 6 when the movable insole 3 is in its first extreme position. Due to the pressure increase, the chamber 6 is elastically deformed, increasing its volume, thus generating a compression force on the upper area of the footwear S, directed towards the sole 2 of the footwear S, thus causing the foot to be fixed in the footwear S.
  • the tank 5 when the movable insole 3 is in its first extreme position, the tank 5 has a maximal volume and the chamber 6 implicitly has a minimal volume.
  • the user puts on the footwear S he progressively compresses, with the heel, the movable insole 3 and implicitly the tank 5 until the movable insole 3 reaches its second extreme position, shown in Figure 2, wherein the tank 5 is compressed/deformed to the maximum, and substantially the whole fluid amount is in the hose 7 and in the chamber 6, the latter being elastically deformed and implicitly having a maximal volume.
  • the system according the first embodiment further comprises a first one-way valve 9, arranged inside the hose 7, and provided with an unlocking system.
  • the unlocking system may preferably be a lever 10 operable by the user by means of an actuating button 11, or may be a remotely operable electronic system.
  • the remotely operable electronic system may be, for example, a locking system provided with an electronic chip, an electric battery and a wi-fi or bluetooth antenna, and remotely controlled by means of a dedicated application installed on the mobile phone.
  • the electric battery may be replaceable or rechargeable by means of the mains power source or by means of charging-by-moving systems of the piezoelectric type.
  • the system according the first embodiment further comprises an elongated container 12, capable to be in fluid communication with the chamber 6 by means of a first two- way valve 13, and capable to be in fluid communication with the environment’s atmosphere by means of a second two-way valve 14, wherein the first two-way valve
  • the second two way valve 13 opens automatically when the pressure within the chamber 6 or within the container 12 exceeds a predetermined threshold value.
  • FIG. 1 the footwear S is shown in the position wherein it is not worn (i.e. put on) by the user, thus the tank 5 is not deformed and the entire amount of fluid 8 is inside the tank 5, and the movable insole 3 is in its first extreme position.
  • the movable insole 3 is in its second extreme position (for example by pressing with the heel of the user), wherein it compresses the tank 5, deforming it to the maximum, such that the fluid 8 is pushed into the hose 7 and through the one way valve 9 into the chamber 6. Since the volume of the tank 5, when full of fluid, in the undeformed state, is greater than the sum of the hose 7 volume and of the undeformed chamber 6 volume, when the movable insole 3 is in its second extreme position, as In Figure 2, the chamber 6 is elastically deformed, increasing its volume, thus generating a compression force on the upper area of the footwear S, directed towards the sole 2 of the footwear S.
  • the value of the ratio between the maximum and minimum volume of the chamber 6 is at least two. This ratio allows, on one hand, when the volume of the chamber 6 is minimal, to provide sufficient space for the insertion of the foot in the footwear S, and on the other hand, when the volume of the chamber 6 is maximal, to ensure an effective fixation of the foot in the footwear S.
  • the compresion force exerted by the chamber 6 on the user's foot is optimal when the volume of the chamber 6 (and implicitly the pressure within the chamber 6) has an optimal corresponding value.
  • the value of the pressure within the chamber 6 must not exceed the pressure associated with the optimal compression force.
  • a maximum threshold value is achieved by means of the container 12, which can be put in fluid communication with the chamber 6 by means of the first two-way valve 13 which opens automatically when the pressure within the chamber 6 or within the container 12 exceeds said threshold value (also called the threshold pressure).
  • the foot will usually swell and exert contextual pressure - depending on the activity performed in that moment - increased on the chamber 6, which will determine the increase of the pressure within the chamber 6 above the threshold value, the opening of the first two- way valve 13 and the passing of a new amount of fluid 8 from the chamber 6 into the container 12.
  • intense effort e.g. intense running, cycling, hiking, all over long distances and long durations
  • the foot will usually swell and exert contextual pressure - depending on the activity performed in that moment - increased on the chamber 6, which will determine the increase of the pressure within the chamber 6 above the threshold value, the opening of the first two- way valve 13 and the passing of a new amount of fluid 8 from the chamber 6 into the container 12.
  • the chamber 6 moves mainly towards the inside of the footwear S.
  • the chamber 6 is, preferably, in contact at its upper part with a rigid portion 15 of the footwear S, and at its lower part with a flexible flap 16, fixed by means of a hinge 17 to the rigid portion 15, at the extremity closer to the tip of the footwear S.
  • hinge must be understood in its broad meaning, which can mean, for example, a joint, a folding line, etc.
  • the rigid portion 15 covers only the area where the laces are usually located on a normal footwear. If the rigid portion 15 would extend to the vicinity of the tip of the footwear, then the bending of the footwear (by flexing of the toes) would be virtually prevented, which would create significant discomfort when walking. Whether the chamber 6 is undeformed or deformed, the rigid portion 15 does not move in the vertical direction (i.e. perpendicular to the sole of the footwear).
  • Figure 8A shows, in front view, the footwear and the undeformed chamber 6, as well as the user’s foot prepared to shoeing the footwear.
  • Figure 8B shows, also in front view, the footwear completely shoed on the user's foot.
  • the chamber 6 is deformed, having maximum volume and exerting pressure on both the user's foot and the rigid portion 15, causing the upper part of the footwear S to move upwards in the direction of the arrow, and the sides L1 and L2 of the footwear to tighten in the direction of the arrows on the laterals of the foot, and possibly, depending on the seams of the footwear, also on the user's ankle, ensuring an additional fixation of the foot in the footwear.
  • the joint 4 may be provided with a first spring (not shown in the figures) for holding the movable insole 3 in its first extreme position when the footwear S is not put on.
  • the hinge 17 may be provided with a second spring (not shown in the figures) that pushes the flap 16 towards the rigid portion 15 of the footwear S.
  • Figure 9 shows a second embodiment of the system for automatically putting on / taking off a footwear S, according to the invention.
  • the differences with respect to the first embodiment are that the fluid 8 is a liquid and the container 12 is further provided with:
  • Both the first and the second embodiment may be further provided with two elastic, deformable primary compartments 20, fixed inside the footwear S, arranged laterally, on either side of the chamber 6, and in fluid communication with the chamber 6 by means of associated primary pipes 21 that are non-deformable in terms of volume. Substantially the entire amount of fluid 8 is in the hose 7, in the chamber 6, in the primary pipes 21 and in the primary compartments 20 when the movable insole 3 is in its second extreme position wherein it compresses and deforms the tank 5 to the maximum, situation where the primary compartments 20 are deformed, by their increase in volume, in the direction towards the inside of the footwear S.
  • each secondary compartment 22 being in fluid communication with the primary compartment 20 situated on the same side, via an associated secondary pipe 23.
  • Substantially the entire amount of fluid 8 is in the hose 7, in the chamber 6, in the primary pipes 21, in the primary compartments 20, in the secondary pipes 23 and in the secondary compartments 22 when the movable insole 3 is in its second extreme position wherein it compresses and deforms to the maximum the tank 5, situation where both the primary compartments 20 and the secondary compartments 22 are deformed, by their increase in volume, in the direction towards the inside of the footwear S.
  • Figure 14 shows the position wherein the movable insole 3 is in its first extreme position and the chamber 6, the primary compartments 20 and the secondary compartments 22 are undeformed.
