A swimming goggle which has an attractive appearance, good watertight properties and which is rather small is disclosed. A single lens formed of a substantially rigid transparent material covers both eyes and has a smooth rearwardly curved front surface so as to minimize resistance and not prevent one from swimming fast. Two watertight elastic members shaped to fit around a user's eyes are mounted on a rear surface of the lens so as not to extend substantially beyond the edges of the lens. A ban...

A swimming goggle includes a pair of right and left eye-cups; a coupling member for coupling the opposed inner end portions of a pair of the eye-cups; connecting members connected to the outer end portions of a pair of the eye-cups, each of which has a length such that the rear end portion reaches the vicinity of the ear when the swimming goggle is attached around the head; and an elastic band provided for joining the outer end portions of the connecting members with each other. Since the length...

A swimming pool includes a swimming tank, which stores water for swimming; and an upstream tank, which stores water to be supplied into the swimming tank. The pool further includes a downstream tank, which stores the water streamed from the upstream tank through the swimming tank; and a pump, which forces the water stored in the downstream tank to the upstream tank. The water in the upstream tank has an energy head that is higher than the water in the swimming tank so as to generate water curren...

Swimming goggles that include a pair of lens assemblies each having an inner end portion formed with a recess and an end wall extending forward. A bridge is formed at each end with an outer leg, an inner leg and an intermediate leg. The outer leg is adapted to be firmly engaged with the recess of the lens assembly and cooperate with the inner leg to retain the end wall therebetween.
