(20) Basically, the SELF LACING AND INDOOR PROTECTION DEVICE, according to the invention, is a device consisting of two lower and upper brackets, operated by a relatively simple mechanism, formed in a first constructive shape of a toothed wheel assembly, which conveys the gearshift movement from the steering wheel to the wheels and then to the gear racks for the shoe fastening slings. In another constructive shape, the device can be operated by a person by heel, both without leaning and without using their hands, by directing the air in an inflatable tank by a pneumatic mechanism to the sliding slings or to an inflatable sling system. The SELF LACING AND INDOOR PROTECTION DEVICE can be used in two ways. In the first way, the SELF LACING AND INDOOR PROTECTION DEVICE is especially used to insert and fix in it the footwear which the person is wearing when wanting to get indoors from outside the premises without getting off their shoes, while protecting the premises from the bacteria on the sole of the shoes with which they came from outdoors. In the second way, the mechanism SELF LACING AND INDOOR PROTECTION DEVICE can be inserted into the sole of a daily footwear, in which case people can benefit from an automatic shoe attachment on the foot. The SELF LACING AND INDOOR PROTECTION DEVICE previously named can be easily manipulated by any person regardless of age, both without leaning and without using their hands. The SELF LACING AND INDOOR PROTECTION DEVICE is composed of the following main parts: 1.—Subassembly A—a mechanical drive device formed, in a first constructive shape, from a toothed wheel gear which simultaneously conveys the movement imparted by the control wheel to the gear racks of the shoe fastening slings by means of the operation by a person by moving forwards and backwards one of the shoes, stacked to the side of the other; or, in another constructive shape, from a pneumatic system that directs air in an inflatable tank to a system of sliding or inflatable shoe fastening slings, in another constructive shape. 2.—Subassembly B—mounting and ground contact device represents the sole and the lower mounting frame of the Subassembly A in any constructive shape, also having the role of tank for the water drained from the shoes worn outdoors. 3.—Subassembly C—a device for mounting and actuating the device in any constructive shape, represents the upper mounting frame of the Subassembly A but also for sealing it, as well as the contact surface and the fixing surface of the footwear (high-grade insole), but also for capturing and directing the water through the drain holes on the surface of its sole in the tank inside the Subassembly B. 4.—Subassembly D—a cylindrical pneumatic device for driving the sliding slings or blowing the inflatable slings by inflating/deflating an inflatable cylinder, driven by the transfer of air from the inflatable tank, in a certain constructive shape.

(21) Subassembly (A), the main mechanical device, is formed by a closing/opening control wheel (5) for operating the entire device on the upper surface in which a toothed wheel (6) is mounted, which engages the first toothed wheel of a succession of toothed wheels (9) acting simultaneously by sliding by guiding rails (19) the gear racks (7) which support the sliding slings (1) for fastening/releasing the footwear inserted through the guiding slots (2). In another constructive shape, the Subassembly (A) consists of the Subassembly (D) which ensures the fastening by transferring air through the transport manifold (29) through the one-way valve (28) by compressing the driving surface of a flap (24) through the flexible supply manifold (44) to the shoe fastening cushions (42) or to the inflatable slings (45) compressed for inflation towards the inside of the shoe against the compression surface (46), and for relaxing the shoe strain by deflating the slings (45) by pressing the external button (22) which fully or partially opens the valve (28) by pressing the button (43) for dosing the shoe strain by exhausting the air from inside to the outside of the air circuit which can be inflated again with air using the filling valve (33).

(22) Subassembly (B), secondary support and mounting device fixes the shoe by means of the flexible shoe hitch for positioning the footwear and forms the ground contact soleplate-type device (3) and the lower frame of the water tank and the device for mounting the Subassembly (A) parts by first inserting and fastening the concentric threaded cylinders (12) into the concentric holes of the control and drive teethed wheels (5), (6) and (9) and subsequently in the lower fixed axles (11), and for the shoe support located on the surface of the Subassembly (C) it is provided with a plurality of rigid support points (10)

(23) Subassembly C, secondary support and mounting device is the lid and insole type device for positioning the shoe and upper/sealing mounting of the Subassembly (A) parts by inserting and fastening the concentric threaded cylinders (12) firstly into the concentric holes of the toothed wheels and the control and drive wheels (5), (6), and (9) and then in the fixed upper axles (14) being formed by a surface of contact with the shoe sole and a mounting surface (17) on the upper surface on which the upper brackets (21) are provided for gear racks and more rubber boots (15) for fastening the footwear, and for providing water drainage out of the shoe surface inside the water and waste tank (4) formed by sealing the Subassembly (B) to the Subassembly (C), it is provided with several holes (16) with filtering sieve to block drainage of bulky residues;

(24) Subassembly D, a pneumatic device which is formed by a mounting cylindrical housing (27) fixed to the Subassembly (C) surface comprising the guiding slots (19) on the surface of which slings (1) are sliding horizontally by means of the arms (38) driven by removing/nearing the pads (37) sliding on the surface of the bracket (40) through the sliding rails (34) by means of the guiding slots (36) by inflating/deflating the inflatable cylinder (39) through the hole (32) which is compressed to open the slings by means of a spring (35).

(25) The SELF LACING AND INDOOR PROTECTION DEVICE can be easily used by people of all ages both for the protection of the premises by the bacteria on the footwear sole by inserting it into the footwear holders and for the automatic fastening of the daily footwear without the need to lean for persons to shoe/unshoe or tie the shoelaces or other types of shoe sling types.

(26) This invention can be applied industrially by manufacturing a large number of SELF LACING AND INDOOR PROTECTION DEVICE, both for the manufacture of footwear for the protection of the premises by the bacteria on the footwear sole, and for the application of the device to the daily footwear.
