Abstract
Diving goggles comprising a strap (3) made of an elastic and deformable
material for fixing said goggles (1) to the user's head and at least one
chamber (5), made of a substantially stiff plastic material, for protecting
the user's ocular orbits, said chamber being connected with said fixing
strap (3) and being provided with a transparent lens (6) and with a seal (9)
assuring the seal between said chamber and the user's face, said strap (3)
being provided hollow, full with air and communicating with said at least
one ocular chamber (5), so that the air contained in said strap (3)
penetrates into said at least one chamber during the dive phase as an
effect of the water pressure increase and passes from said at least one
chamber (5) to said strap (3) again during the emersion phase due to the
inverse effect.
Description
- The present invention concerns diving goggles.
- In particular, the diving goggles according to the invention are provided with means for compensating the water pressure variations during the dive and emersion phases.
- The 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.
- Diving goggles are described, for instance, in the documents US 5,129,109, US 5,890,237 and US 6,349,420.
- In all this variety of models, however, means for compensating the water pressure variations during the dive and emersion phases are not provided so that, when using the known diving goggles during the dive phase, the water pressure compresses the chambers bearing the goggles lenses, thereby bringing said lenses very close to the eyes. Said compression, during the emersion phase, originates the so called "suction" phenomenon, a far more serious effect acting directly and harmfully on the user's eyes.
- It is an object of the present invention to overcome the above mentioned drawback by providing diving goggles equipped with means for compensating the water pressure variation in the eyes area, both during the dive phase and the emersion phase, thereby avoiding in this way said harmful effects.
- Advantageously, 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.
- A preferred embodiment of the invention will be now described in detail with reference to the hereby attached, non-limitative, exemplary drawings, wherein:
- Figure 1 is a perspective view of the diving goggles according to the invention; and
- Figure 2 is a plan view of the diving goggles of Figure 1.
- As it is clear from the Figures, the
diving goggles 1 according to the invention are quite similar to other suchlike goggles presently available on sale. Thediving goggles 1 comprise astrap 3 to be fixed to the user's head and a pair ofocular chambers 5, made of a substantially stiff plastic material, connected with thefixing strap 3 by means of two adjustingbuckles 11. Saidbuckles 11 are arranged one at each side and allow to adjust the adhesion of thegoggles 1 to the user's head. Saidocular chambers 5 are provided with transparent lenses 6 and withseals 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. - Although the invention is herein described in detail with reference to diving goggles provided with two separate
ocular chambers 5, one at each ocular orbit, it should be remarked that the invention may be equally applied to those diving goggles models providing for a unique chamber having an elongated shape and covering both user's ocular orbits. - Advantageously, according to the invention, the
strap 3 for fixing saidgoggles 1 to the user's head are made of rubber or of a similar elastic and deformable material. Thestrap 3 is provided hollow and full with air in order to substantially constitute an air plenum chamber communicating with theocular chambers 5. - Taking into account that the
ocular chambers 5 are substantially stiff and thus have a fixed volume while thestrap 3 connected to them is made of an elastic and deformable material, the working of the goggles according to the invention turns out to be clear and intuitive. - During the dive phase, 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 theocular chambers 5 in which it is in this way compensated the effect of said water pressure increase. - During the emersion phase, the water pressure decrease causes the air to be sucked down again from the
ocular chambers 5 towards thestrap 3 which will thus assume again its original shape and size. - For a good working of the goggles according to the invention, it is clear that it is essential not to obstruct the opening for the air passage neither while adjusting the
strap 3 nor while using the goggles. - It is likewise evident that the same working would be obtained in case of diving goggles provided with a unique elongated chamber for both user's ocular orbits.
- Thanks to the present invention, it is therefore possible to avoid both the compression of the orbits during the dive phase and, during the emersion phase, the far more harmful "suction" effect which may cause the breaking of the orbital capillary vessels.
- For greater safety, in order to avoid the danger of said "suction" effect, 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 thechambers 5 bearing the lenses 6. - Preferably, like in the shown embodiment, a
valve 13 is provided for eachocular chamber 5. - Finally, it should be remarked that the greater the volume of the recess of the
strap 3 with respect to the volume of theocular chambers 5 is, the greater the depth attainable by wearing thegoggles 1 according to the invention before suffering the above mentioned drawbacks is.
Claims (6)
- Diving goggles (1) comprising a strap (3) made of an elastic and deformable material for fixing said goggles (1) to the user's head and at least one chamber (5), made of a substantially stiff plastic material, for protecting the user's ocular orbits, said chamber being connected with said fixing strap (3) and being provided with a transparent lens (6) and with a seal (9) assuring the seal between said chamber and the user's face, characterised in that said strap (3) is provided hollow, full with air and communicating with said at least one ocular chamber (5), so that the air contained in said strap (3) penetrates into said at least one chamber during the dive phase as an effect of the water pressure increase and passes from said at least one chamber (5) to said strap (3) again during the emersion phase due to the inverse effect.
- Diving goggles (1) according to claim 1, wherein said ocular chamber (5) is connected with the fixing strap (3) by means of a pair of adjusting buckles (11), said buckles (11) being arranged one at each side and allowing to adjust the adhesion of said goggles (1) to the user's head.
