Definitions
- the present invention concerns diving goggles.
- the diving goggles according to the invention are provided with means for compensating the water pressure variations during the dive and emersion phases.
- goggles for diving into water, or "scuba" goggles are largely known and available on sale in a wide variety of types and models having different quality and features.
- the strap for fixing the goggles to the user's head is provided hollow, full with air and communicating with the ocular chamber or chambers bearing the lenses.
- the chambers as an effect of the water pressure increase during the dive phase, will be filled by the air contained in the plenum chamber constituted by said hollow strap, and they will be gradually emptied during the emersion phase due to the inverse effect.
- the diving goggles 1 are quite similar to other suchlike goggles presently available on sale.
- the diving goggles 1 comprise a strap 3 to be fixed to the user's head and a pair of ocular chambers 5, made of a substantially stiff plastic material, connected with the fixing strap 3 by means of two adjusting buckles 11.
- Said buckles 11 are arranged one at each side and allow to adjust the adhesion of the goggles 1 to the user's head.
- Said ocular chambers 5 are provided with transparent lenses 6 and with seals 9 assuring the seal to the user's face and are connected between them through a flexible bridge 7. If necessary, the bridge 7 may be hollow in order to make said chambers communicating each other.
- the strap 3 for fixing said goggles 1 to the user's head are made of rubber or of a similar elastic and deformable material.
- the strap 3 is provided hollow and full with air in order to substantially constitute an air plenum chamber communicating with the ocular chambers 5.
- the working of the goggles according to the invention turns out to be clear and intuitive.
- the pressure increase of the water surrounding the user causes the deformable strap 3 to be compressed and the air therein contained to pass to the ocular chambers 5 in which it is in this way compensated the effect of said water pressure increase.
- the water pressure decrease causes the air to be sucked down again from the ocular chambers 5 towards the strap 3 which will thus assume again its original shape and size.
- At least one vacuum relief valve 13, able to prevent an excessive widening of the recesses, is provided in the stiff part of the goggles integral with the chambers 5 bearing the lenses 6.
- a valve 13 is provided for each ocular chamber 5.
