Abstract: A double-sided eyelet, of having a first head (2) provided with an element (3) having a shank (4) and a second head (8) provided with an element (9) having a shank (10), wherein the aforesaid heads (2,8) are mutually closed on the hole (6) of a support (7,17). According to the invention, the second head (8) of the eyelet is provided with a seat (14) suitable to receive the folded edge (16,18) of the shank (4), in which the size of the aforesaid folded edge is variable as a function of the thickness of the support (7,17). In comparison with known eyelets for leatherwear and for clothing in general, the eyelet according to the invention offers the advantage that, while preventing the formation of unsightly excess thicknesses on the coupling section of the shank of the first head inside the hole of the second head of the eyelet.

Abstract: A snap fastener, of the type comprising a female part (2) including a spring (11, 11a, 11b) and a male part (4) including a stem (5) for engagement with the spring, wherein a chamber (10, 10a, 10b) is provided for housing the spring and including shoulders (12, 12a, 12b) on a buttoning side, the shoulders having a length (L1) longer than a length (L2) of shoulders (13, 13a, 13b) arranged on the opposite side. Thus, a differentiated effort buttoning and unbuttoning mechanism between the stem (5) and the spring (11) is achieved. With respect to prior snap fasteners, the inventive snap fastener provides the advantage of requiring very small buttoning efforts, much smaller than those necessary for unbuttoning the snap fastener, thereby facilitating the snap fastener closing operation while providing a tightness closure upon having buttoned the snap fastener male and female parts.

Abstract: A pressure snap fastener with a bivalent closure comprises a first portion, to be associated with a first flap, and a second portion, to be associated to a second flap; where the portions, as associated with one another join the flaps. The pressure snap fastener further includes first temporary engagement means providing a temporary closure, in which the two portions are joined by a weakly joining and are free of partially swinging, and include second stable engagement means, providing a stable closure, in which the two portions are tightly coupled.

Abstract: A snap fastener, of a laterally engageable type, for garments in general, comprises a male part including a contoured projection and to be clamped to a first flap of the garment article, and a female part, including a female part hollow body having an inner cavity and clamped to a second flap of the garment article, the hollow body including, at a top part thereof, a seat for laterally engaging therein the contoured projection, the seat comprising an elongated slot including an open end portion, formed on the peripheral surface of the hollow body. With respect to a prior like snap fastener, the inventive snap fastener has the advantage that it allows the garment article to be buttoned up by a simple lateral engaging of the male portion into the female portion, without requiring additional axial movements.
