Description
FIELD OF THE INVENTION

The invention relates to the shoe industry, and namely to the method of affecting a shoe product, in particular to a method of putting on (shoeing) and taking off (unshoeing) closed type shoe product without manual manipulations.

BACKGROUND OF THE INVENTION

There is a known shoe product with a self-retracting laces system, which includes a sole, an upper part, laces and a blocker. There is a heel reservoir with liquid built into the sole. The liquid can be fed to the pistons integrated into the sole, the pistons are connected to the laces and pull them up (RU 2670322, IPC A43C 19/00, published 22Oct. 2018).

The disadvantages of this solution are following: The need to raise a leg to take off the shoe product, which requires the actuation of the unlocking element; when the system is unlocked, the tension of the laces is loosened, but the top of the shoe product is not opened, so there is no possibility of taking off and putting on the shoe product without using hands (there is no mechanism to open the top of the shoe product).

There is a known mechanism, both for fixing the prepared (equipped with a special mechanism) shoe product, and for attaching a conventional shoe product, which allows to take off and put on a shoe product without leaning or using hands. The device employs a drive mechanism of the assembly, an assembly of the lower attachment assembly, an assembly of the upper attachment assembly and a shoe product positioning and a pneumatic assembly (EP 3448192, IPC A43B 3/18, A43B 3/16, A43B 11/00, published 6 Mar. 2019).

The disadvantages of the mechanism are following: When embedding it into a conventional shoe product, it is necessary to use hands to take off and put on the shoe product, because when the system is unlocked, the tension of the laces is loosened, but the top of the shoe product is not opened (there is no mechanism to open the top of the shoe product); when using a pneumatic system, unlocking will not lead to sufficient movement of the laces, since the area of the working surface is small, and the gas has a high compression ratio; when using a pneumatic system, there is a risk of pinching the sock (clothing) or foot in the element of the drive surface under the heel; when using a gear ring system, the steering wheel is not fastened and can spin unintentionally or spontaneously from the tension of the laces, which leads to loss of control over the tension of the laces.

There is a known shoe product, in which an unidirectional closing mechanism has actuation system and an automatic opening mechanism. The laces of a shoe product are brought to the inside part of the heel where they are tightened or loosened by a tensioning mechanism. The tensioning mechanism includes a rotating central shaft, which can have mounted on it drums, a ratchet clutch or ratchet cam disk, a ratchet drive coil, a compression spring, a return spring, a ratchet wheel and a release lever, including a stopper and a cam drive rod, which run along the central shaft and serve to tighten and loosen the laces (U.S. Pat. No. 7,096,559, IPC A43B 11/00, A43C 11/00, A43C 7/00; B23P 19/04, published 29 Aug. 2006).

The disadvantages of the known method are following: The need to use hands to put on and take off the shoe product, because when the system is unlocked, the tension of the laces is loosened, but the top of the shoe product is not opened (there is no mechanism for opening the top of the shoe product), and also the tightening of the laces is indirectly done manually; disengagement of the tension mechanism and its rotation, when taking off the shoe product, can lead to entanglement of the laces and the formation of knots on them in the body of the mechanism, since there is no element supporting the laces in a state of tension; insufficient ventilation of the body of the tensioning mechanism can form an aggressive environment for its elements when moisture enters it and can lead to their rapid failure.

There is also a known shoe product with an automatic lacing system. The automatic lacing system is ensured by a rotating device and a set of straps, which can be automatically loosened and tightened in order to switch between the opened and closed position of the top of the shoe product. The device additionally includes an automatic fastening system for the upper part of the ankle joint (US 2016219985, IPC A43B 3/00, A43C 11/14, published 4 Aug. 2016).

The disadvantages of this system are following: To actuate the device for closing and opening a shoe product, a power source is needed, which must be replaced or recharged periodically; insufficient ventilation of the body of the closing and opening device can form an aggressive environment for its elements when moisture enters it and can lead to their rapid failure; the presence of a rotary device and a power source in the device leads to an increase in the mass of the shoe product.

The closest technical solution to the claimed invention is a device for automatic tightening of shoe laces, containing a lace, a lace guide tube, a pedal and a base. One end of the pedal is pivotally connected to one end of the base, and a fixed hole is formed at the other end of the pedal to drive the lace. Between the pedal and the base there is an elastic body and a part of the lock keeper, which is used to fix the elastic body and is controlled by a switch located on the outside of the heel (CN 204273425, IPC A43C 11/00, published 22 Apr. 2015).

In the known solution, the automatic shoe lace tightener has the following characteristics: The foot shall press the pedal to tighten the shoe lace and put on the shoe product. In this case, the pedal presses down the elastic body to accumulate power and is blocked by a snap-in part of the lock. The switch is actuated to unlock the latching part of the lock and release the stored power to take off the shoe product. In this case, the pedal rebounds and activates the lift, which loosens the lace to take off the shoe product. The automatic shoe lace tightener is simple in design, small in size, does not affect the comfort and functioning of the shoe product upon its installation.

The disadvantages of the prototype are following: There is a risk of pinching the sock (clothing) or foot in the drive surface element under the heel; the need to use hands to put on and take off the shoe product, because when the system is unlocked, the tension of the laces is loosened, but the top of the shoe product is not opened (there is no mechanism to open the top of the shoe product).
