Abstract: A buckle includes a base that receives therein a pressing board having a front end pivotally coupled to the base and a rear end provided with a clutch portion for clutching a tooth of a head strap, and an operating member that is received in the base and corresponds to a back of the pressing board. The operating member has two buttons. When an arcuate bar pressing against the operating member is pressed inward, the arcuate bar deforms and pushes the pressing board to swing outward, making the clutch portion disengage from the tooth of the head strap, so that length adjustment of the head strap is allowed. After the adjustment, the pressing board automatically swings back due to the tension of the head strap, so that the clutch portion clutches another tooth of the head strap to position the head strap.

Abstract: A fastening buckle for fastening a snorkel to swimming goggles includes a strip-holding member and a snorkel-holding member. The strip-holding member has a resiliently depressible hanging section and has an outer surface formed with an inclined plane. The snorkel-holding member has a gripping portion laterally formed with a socket for receiving the hanging section of the strip-holding member. The socket has an outer wall formed with a cut-away section for abutting against a bottom edge of the hanging section. The socket further has a resiliently depressible pressing button extending downward from a top thereof to hang over the cut-away section and abut against the inclined plane of the hanging section. When pressed, the pressing button presses the inclined plane to expel the hanging section downward from the cut-away section, allowing convenient disengagement between the snorkel-holding member and the strip-holding member.

Abstract: The invention relates to a support apparatus for a front-mounted breathing tube, comprising a breathing tube inserted into a breathing tube positioning member, two ball-pivot portions arranged symmetrically on one side thereof, and a concave slot is formed between the two ball-pivot portions for swinging elastically; two forehead positioning members are arranged symmetrically and a head-band connecting portion is at the outer side thereof; the inner side includes a connecting portion having ball-socket portions for receiving the ball-pivot portions therein. With the ball-pivot portions on the breathing tube positioning member and with the ball-socket portions of the forehead positioning members, the forehead poisoning members can swing in different directions and angles.

Abstract: Light-emitting semiconductor packages and related methods. The light-emitting semiconductor package includes a central barrier, a plurality of leads, a light-emitting device, a first encapsulant, a package body, and a second encapsulant. The light-emitting device is disposed in the interior space defined by the central barrier and is electrically connected to the leads surrounding the central barrier. The light-emitting device includes upper and lower light-emitting surfaces. The first encapsulant and the second encapsulant cover the upper and lower light-emitting surfaces, respectively. The package body encapsulates portions of the central barrier, portions of each of the leads, and the first encapsulant. The light-emitting semiconductor package can emit light from both the upper and lower sides thereof.

Abstract: A quick-release coupling structure between a gas delivery tube and a respiratory mask includes a connecting member assembled to the respiratory mask and a pipe-end joint detachably coupled to the connecting member. The connecting member has two bendable tongues each having a protuberance formed on an outer surface thereof. The pipe-end joint has two sockets for receiving the tongues, and the sockets are provided with resilient members that press upon the tongues and can resiliently retract. The pipe-end joint has two retaining recesses at the sockets for retaining the protuberances. When the pipe-end joint is combined with the connecting member, the protuberances are retained by the retaining recesses. When the resilient members are pressed inward, the tongues retract and the protuberances leave the retaining recesses, so the pipe-end joint can be easily detached. Thereby, easy attachment and detachment between the gas delivery tube and the respiratory mask can be achieved.

Abstract: A forehead abutting device for use with a respiratory mask without adjustment thereof is provided. The upper end of the respiratory mask extends upward to form a support portion. A forehead cushion component, which has a forehead cushion and is capable of protracting and retracting resiliently and automatically, is disposed at the upper end of the support portion. The forehead cushion component includes a forehead cushion and a pipe portion extending therefrom. The terminal end of the pipe portion abuts against a receiving hole portion disposed at the upper end of the support portion. A resilient element capable of pushing the forehead cushion component outwardly and resiliently is disposed inside the receiving hole portion. The mask is fixed at three points and accurately positioned, fits different forehead contours through the forehead cushion component, imposes less burden on the nasal bridge, and prevents gas leakage.
