A size adjustment arrangement for a garment comprises a base member, a ratchet member, a line, a spool, and an actuator. The line is wound on the spool with the line extending through at least one channel in the garment. The actuator is selectively rotatable in a first direction and a second direction without activation of any release mechanism. When a first force is applied to rotate the actuator in the first direction, the line is wound upon the spool. When a second force is applied to rotate the actuator in the second direction, the line is unwound upon the spool. The ratchet member and the spool are blocked from rotation when neither the first force nor the second force is applied to the actuator.

A damage resistant shoelace may include a lace and a treatment composition applied to at least a portion of the lace. The treatment composition may include a superglue adhesive, an adhesive, and a sealant, such as a liquid rubber sealant coating in aerosol form.

A rotatable cord tensioning device is disclosed which is configured to include apertures for affixing one or more cords. Other apertures in the rotatable cord tensioning device are disclosed for securing the cord tensioning device in a rotated position. The rotation of the cord tensioning device tensions the cord by effectively shortening the length of the cord.

An inductor includes a coil having a plurality of coil patterns and external electrodes connected thereto. An innermost coil pattern and an outermost coil pattern in the coil grow using first and second insulating wall as growth guides and the inductor has a structure in which there is no deviation in thickness and shape between the coil patterns.

A method includes pressing a macromolecular material to form a successive reflective layer, heating the reflective layer to a preset temperature value, stirring luminous powder and fluorescent powder at a high speed so that the luminous powder and the fluorescent powder are mixed evenly to form a luminous blank, evenly painting the luminous blank on the reflective layer, drying the luminous blank at a predetermined temperature value to form a luminous layer, and cooling the reflective layer and the luminous layer to produce a substrate which has reflective and self-luminous features. Thus, the luminous layer of the substrate emits light in a dark environment by reflection of the reflective layer of the substrate.

A pressure fixing device applied to a shoe is disclosed. The pressure fixing device includes an inflatable shoe tongue, a first air pump and a control module. The control module drives the air to flow out of the inflatable shoe tongue according to a second enabling signal so that the inflatable shoe tongue tends to shrunk and moves toward the wear space to attach to a user's instep. The control module drives the first air pump to pump the air flowing into the inflatable shoe tongue according to a first enabling signal, so that the inflatable shoe tongue tends to expand due to the air inflated and moves away from the wear space to enlarge the opening, by which the user can wear or take off the shoe easily.

A pneumatic elastic band comprises an outer portion, an inflatable portion and a nozzle. The outer portion has a strip-shaped structure with elasticity. The inflatable portion comprises a plurality of expansion portions and a plurality of communication portions. Each of the communication portions is connected between two of the expansion portions adjacent to each other for defining a plurality of gaps. The nozzle is disposed on a surface of the outer portion and communicated with the inflatable portion. When a gas is guided into the inflatable portion through the nozzle, the plurality of expansion portions of the inflatable portion are inflated to fill the gaps and make the inflatable portion contract inwardly, so that the outer portion contracts inwardly and deforms, wherein when the gas is guided out of the inflatable portion, the inflatable portion is deflated and loosened to return to an uninflated state to loosen the shoe.
