Abstract: An adjusting strap is provided. The adjusting strap has a strap body and at least one fastening portion. An end zone of the strap body has at least one fastening hole, which is disposed along the strap body in a lengthwise direction. The fastening portion is disposed on the strap body and located at an inside area adjacent to the fastening hole, the at least one fastening portion is integrally formed with the strap body and extends away from a top surface of the strap body. When the end zone of the strap is bent in reverse, the fastening portion is capable of threading through the fastening hole to be in position.

Abstract: A goggle mask is provided. The goggle mask includes at least one check valve device with a soft body and at least one valve disk. The soft body is integrally connected with the soft nose masking portion of the goggle mask. The soft body has a draining hole. The valve disk is adapted to movably cover the draining hole. With this arrangement, there are no hard objects that come into contact with the user's face, so the user may feel less uncomfortable. A check valve device and a method for manufacturing a check valve device of a goggle mask are also provided.

Abstract: A buckling device for fastening a belt is provided. The buckling device comprises a first portion, a second portion, an elastic portion and at least one push portion. The elastic portion is disposed between the first portion and the second portion. The second portion engages with the belt and the belt is fastened. The at least one push portion is integrally formed with the elastic portion and is exposed from the first portion and the second portion. The at least one push portion is adapted to be pushed inwards by an external force to force the elastic portion to extrude outwards so that the second portion is forced to move outwards to release the belt.

Abstract: A buckling device for fastening a belt is provided. The buckling device comprises a first portion, a second portion and an elastic portion. The elastic portion is made of a material with a shore hardness substantially between A10 and A95. The elastic portion contacts the first portion and the second portion, so that the second portion engages with the belt and the belt is fastened.
