  • Patent number: 11925242
    Abstract: A pull ring for a buckle assembly that has a main body with a first hook element facing a rear end, and an actuation button. The actuation button is connected to the main body by a spring so that the actuation button can move between an extended resting position and a compressed position. The actuation button has a second hook element on a bottom surface and which faces the front end of the main body. The pull ring is connected to the main body and actuation button by fitting the pull ring around the first hook element, pressing the actuation button, pivoting the actuation button and main body until the second hook element is disposed within a central aperture of the pull ring, and releasing the actuation button so that the pull ring is retained in the hook elements under pressure by the spring.

  • Patent number: 11622606
    Abstract: A buckle assembly is formed by a male portion, a female portion and a rotor. The male portion has a base body, and at least one locking leg having a first latching element. The female portion has a base body with an interior cavity and at least one guide slot. The rotor is seated in the interior cavity and has an actuation surface, a second latching element for engagement with the first latching element, and an actuating mechanism that orients the rotor in a locked position in a resting state of the buckle assembly. The male portion is locked to the female portion by inserting the locking leg into guide slot until the first latching element engages the second latching element. The male portion is released from the female portion by pressing the actuation surface to rotate the rotor until the latching elements are disengaged from each other.

  • Patent number: 11606986
    Abstract: A securing device that allows adjustable securing of a face mask, face shield or goggles to a wearer's head is formed from a first portion having a strap, a first end with a securing button and a connecting element, and a second portion having a strap, a first end with a securing button and a connecting receptacle for interacting with the connecting element to connect the two straps together. The securing buttons are formed from a top plate connected to a bottom plate via a connecting leg having a cross section with an acute angle. The bottom plate has slits extending from an outer edge to the connecting leg on both sides of the acute angle, such that a cord is securable to the securing button by inserting the cord into one of the slits, wrapping the cord around the acute angle of the connecting leg and exiting from the other of the slits.

  • Patent number: 11533970
    Abstract: A buckle assembly has a first buckle portion, a second buckle portion and a locking lid. The first and second buckle portions have magnets that attract each other. The locking lid is connected to the first buckle portion and has a sliding element, a spring connected to the siding element, a pivot axle for connecting the locking lid to the first buckle portion, and front and rear attachment elements. The second buckle portion has engagement flanges for engaging the front and rear attachment elements. The first and second buckle portions are connected together by placing the first and second buckle portions together so that the magnets attract each other, sliding the sliding element against a force of the spring until the attachment elements engage the engagement flanges, and then releasing the sliding element to return the spring to a resting position.

  • Publication number: 20220395080
    Abstract: A strap adjustment device has a retaining body and a strap connector adjustably mounted in the retaining body. The retaining body has an interior cavity and a top opening extending in a horizontal direction, and at least one protrusion extending into the cavity. The strap connector has a strap connecting portion with at least one strap connecting element, and an adjustment portion disposed inside the cavity. The adjustment portion has a lower locking element and a spring mounted its end. When the spring is in a relaxed state, the protrusion prevents movement of the strap connector in the horizontal direction by blocking the lower locking element. Pressing the strap connector against the force of the spring moves the lower locking element below the protrusion, so that the strap connector can be moved in the horizontal direction to a new position within the retaining body.
