Lluch's third snorkel-mask. The patent:
Specification for a Utility Model for twenty years, in favour of Mr. Miguel Lluch Codolá -Spanish nationality- residing in Barcelona - Balmes, 335, for:
-Underwater GOGGLES-
The present utility model references underwater goggles that, due to the characteristics of their construction, surpass all known ones, for which their use in underwater hunting and work to be carried out underwater is highly recommended.
Those interesting features, in the goggles that are claimed, are:
- They allow dual breathing through the nose and through the mouth, carrying out the first through the inside of the goggles, and the second through a different conduit, which has a mouthpiece at its end to be bitten by the user.
- Valve layout.
The organisation thus provided by the setup of the new improved underwater goggles to which we refer, avoids the great fatigue in breathing that is experienced in the known ones of other models.
For greater clarity, we will specify the arrangement of the goggles with reference to the attached figures, which correspond only to one embodiment, without any limiting character, which is presented as an example of realisation with the indicated purpose, since the form, materials and dimensions of the different parts of the glasses, will be established in each case in accordance with what is deemed pertinent, for the specific application in question, without such variations, as well as those that may be made in presentation or organisation details, affect the claimed essentiality, so the glasses that are built within the general idea outlined with any of these modifications, will not be but variants, equally understood and protected by this registration.
Figure 1 illustrates the overall view, from the front and side on which the second breathing tube is arranged, of the goggles assembled with all their elements.
Figure 2 refers to the analogous view with the goggles placed on a user’s head, and from the opposite side than the previous figure.
Figure 3 represents the inside of the part covering the eyes and nose, i.e., of the goggles themselves.
Figure 4 represents the longitudinal projection in elevation of the setup of the goggles.
Figure 5 shows the cross-section of the breathing ducts and the valve, and the projection on the plane of that section of the elements on one side of the goggles.
Figures 6, 7 and 8 correspond, respectively, to the elevation view, seen from above and from below, of the fixed part of the valve.
Figure 9 presents the section of said part, along the plane indicated in AB on the previous figure.
Figures 10, 11 and 12, analogously to figures 6, 7 and 8, indicate the layout of the moving part of the valve.
Figure 13 details the cross-section of the moving part of the valve, along the plane indicated in CD on figure 11.
Figures 14, 15 and 16, in elevation views and from their upper and lower parts, show the layout of the auxiliary valve.
Figure 17 is the cross-section of said valve, along the plane indicated in EF on the previous figure.
With reference to said figures and the numbers that on them designate the parts and details of the represented object, which are of interest and the purposes of this memory, the description of the same is as follows:
The object to which we refer is made up of valve 1 (figs. 1 and 2) which, through conduit 2, communicates with part 3 of hardened rubber, which in turn has two branches:
One for the communication conduit 17, by means of part 16, with the breathing nozzle 15 and the other that, through the metal tube 5, communicates with the flexible conduit 7, which through its nozzles 6 and 10 fits, respectively, in said tube and in the upper part of the frame 11, carrying the transparent part 12, through which vision is made.
This armour adapts to the face by the wings 14, attached to the reinforcements 13 that make up the whole.
In the upper part of the armour, see the buckles 9, for the strap 8 for fastening on the head, which has the lugs 4, crossed by the mentioned metal tube 5.
On either side of the strap 8, other side straps 22 are arranged, provided with projections 21, which with the buckles 20 allow the strap to be given the necessary length in each case.
The lateral straps 22 are attached at their lower part to the strap 19, carrying the parts 18 intended to protect the ears, whose strap enters the buckles 24 at its ends, which with the projections 23 allow the adjustment of said strap 19 behind the head, according to the above.
In Figure 1, the part that the user holds with the teeth is indicated at 25; and figure 3 shows the shape of the wings 14, for adaptation to the user’s face.
As regards the valve that comfortably allows breathing, through ducts 5-7 and 17, it is made up of: the cover or box designated with number 1 in figures 1 and 2, the fixed piece 26 (figs. 6 to 8), the moving part 29 (figs. 10 to 12) and the valve 31 (figs. 14 to 17).
The so-called fixed part 26 has, embedded in its bottom, the metal rods 27 and the rim 28 around the edge, by which it is held in the ring 32 of the cover 1.
The moving part 29 has recesses for the springs 30, which only fulfil the mission of facilitating the coupling of this part in the fixed part 26, when the rods 27 enter said springs. In the upper part, the auxiliary valve 31 is mounted, and in the lower part, the disk 34, which can make a small path between the radial projections 35 and 36.
These parts that make up the valve also have the following details:
Its box or casing 1 has the rim 37, joined by the straps 38 to the ring 39, which in turn has the projections 40, which hold the moving part 29 by its projection 41, when the valve is assembled.
This projection 41 is the one that rests on the edge 42 of the fixed part 26, when assembling said valve.
The fixed piece 26 has a cavity 33 at its bottom, crossed diametrically by the crosspiece 44, which has a central cylindrical part 43, in which the solid plug 45 is embedded.
The auxiliary valve 31 has the channel 46 (fig. 17) and below it the wings 47, in the form of circular sectors, the cylindrical piece 48 made of hard material being embedded in the centre of the assembly.
NOTE
This record comprises the following claims:
1.- Underwater goggles characterised in that it is provided with a valve made up of a rubber cover or box, which communicates with the breathing tubes and houses at its bottom a fixed, hollow cylindrical piece, provided at its end with a bottom, which has a circular hole, in which in turn a crossbar is arranged, which has a plug of hard material embedded in its centre, arranged towards the bottom of the box, in whose bottom the ends of two metal rods are also fixed, that protrude from the other side of the fixed piece, which in turn is provided with a rim, by which it fits in the aforementioned eyebrow.
2.- Underwater goggles, characterised in that a hollow piece, also made of rubber, is attached to the fixed piece, which has, in diametrically opposite positions, two channels for the passage of the aforementioned rods and the accommodations for them, made in a central rim of the piece and in some ears arranged in the part of the mobile piece that, when mounting it in the fixed piece, is towards the inside of the same; these housings are internally reinforced with helical springs that guide the rods.
3.- Underwater goggles, characterised in that the hollow moving part, in the part that is towards the outside, has a disc mounted, also made of rubber, which can move between radial projections that limit its travel.
4.- Underwater goggles, characterised in that the mobile part at its other end has an auxiliary valve mounted, which has a lateral slot, on one side of which the valve is solid, while on the other, it has three fins, shaped like circular sectors; going in the centre of this part embedded a plug of hard material.
5.- Underwater goggles, characterised in that the valve cover or box communicates at one end with a conduit that branches into two others, one that ends in the piece that covers the nose and eyes, and the other that reaches the mouthpiece that is held with the teeth; and, at the other end, it presents the annular socket for the rim of the mobile part.
6.- Underwater goggles.
