Abstract
Description
- The present invention relates to a diving mask, and in particular to a diving mask with strap provided with regulation means spaced out from the ends connected to the mask face.
- In most diving masks commonly on the market the strap is introduced into two buckles connected to the two sides of the mask body, and therefore the regulation of the strap tension is carried out in these two connection points. As a consequence, the regulation which has been carried out on each buckle must be analogous to the other in order to avoid the unbalance of the mask, so that the regulation is difficult to carry out with the mask on.
- An interesting solution to this kind of problem has been provided by the Italian Patent No. 1281802 by the same applicant, which describes a diving mask consisting of a face and a strap connected to the sides of said face; said strap consists of: two support elements open on one end and each connected on the other end to one side of the face of said mask, said support elements housing a pivot pin; and a band-shaped element made of elastomeric material, whose two ends are brought around said pins, said ends being connected with adjustable length to the two respective portions of a rapid-release buckle.
- In practice, this kind of solution moves the regulation means for the strap tension from the points of connection with the mask body to a position which is near the back portion of the diver's head, on the ends of the rapid-release buckle portions, thus making the regulation much easier.
- However, also this kind of approach is not without disadvantages; in particular, a problem consists in the fact that the elastomeric band-shaped element undergoes the tension determining the adhesion force of the mask face onto the diver's face, and therefore its regulation, though differently from what took place for known masks, is rather difficult. Moreover it is exactly this kind of tension which subjects said band-shaped element to a load which can endanger its integrity.
- The present invention aims at providing a mask in which the strap tension can be regulated with an extremely limited effort, and in which the tension load is absorbed outside the regulation means.
- The object of the present invention, therefore, is a diving mask consisting of a stiff body, which connects a face made of elastomeric material and a crystal one to the other, and a strap connected to the sides of said face, the regulation means for the tension of said strap being spaced out from the ends of said strap, said ends being connected to the mask face, characterized in that said strap consists of: two spacers made of elastically extensible material, and preferably elastomeric, connected on one end to the mask face, and provided on the other end with return means for a flexible, though not extensible, band-shaped element, which is provided on its ends with closing means and regulation means.
- The spacers can be carried out as one piece together with the mask face made of elastomeric material, or they can be connected to the face by means of a removable coupling of their end with the stiff body of the mask, said body being mounted on the face.
- Further advantages and characteristics of the mask according to the present invention will be evident from the following detailed description of some forms of embodiment of said invention, carried out as a mere non-limiting example, with reference to the enclosed drawings, in which:
- Figure 1 is a top plan view with sectioned parts of a first form of embodiment of the mask according to the invention:
- Figure 2 is lateral elevation view of a second form of embodiment of the mask of the invention;
- Figure 3 is a top plan view with sectioned parts of the form of embodiment in figure 2;
- Figure 4 is a lateral elevation view of a third execution variant of the mask according to the invention;
- Figure 5 is an exploded perspective view of a detail of the mask in figure 4;
- Figure 6 is an exploded perspective view of a detail belonging to a fourth execution variant of the mask of the invention; and
- Figure 7 is an exploded perspective view of a detail belonging to a fifth execution variant of the mask of the invention.
-
- Figure 1 shows a first form of embodiment of the mask according to the present invention; the numeral 1 indicated the mask face, generally made of elastomeric material, to which a crystal 4 is connected by means of the coupling with the
stiff body 2, made of thermoplastic material. From theedge 201 of the mask, which controls the sealed introduction of the crystal 4 into thebody 2, thespacers 101 start, said spacers being carried out as one piece together with said face 1, on which free end a ring-shaped loop 111 is formed, into which said band-shaped element 203 returns, said element constituting, together with saidspacers 101, thestrap 3 of the mask. Thespacers 101 pass through thebody 2 on thegroove 102 formed in said body; theframe 112 blocks the crystal 4 against theedge 201 and closes thegroove 102. The headpiece 303 is introduced into the band-shaped element 203, the ends of said headpiece being coupled with the closing and regulation means 213. - Figure 2 shows a second form of embodiment of the mask of the invention; the same parts are indicated with the same numerals. In this case the
strap 3 comprises thespacers 102, substantially V-shaped, whose twoarms 113 are connected to thebody 2 of the mask thanks to the introduction of theterminal pins 123 into thecavities 202 formed on the bottom of thehollow 332 on the side wall of thebody 2. On the opposite end thespacers 103 show theslot 133 which allows the return of the band-shaped element 203. Moreover, acap 302 is placed onto the ends of the arms with thepins 123, said cap being coupled with the hollow 332 by means of thetoothed protuberances 312. As can be seen from figure 3, thetoothed protuberances 312 are introduced into thehousings 322 formed in the hollow 332. Thearms 113 of thespacer 103 are placed into the grooves 342. - The form of embodiment shown in figure 4 shows the
spacer 403 provided with a ring-shaped extension 413, which is destined to be coupled with thepin 412 protruding within thecavity 402; the portion ofspacer 403 near the ring-shaped extension 413 is placed into theflared groove 422. The connection is protected by thecap 432, said cap being provided with theguide tooth 452 and with thetooth 442 for the coupling with thebody 2. From figure 5 it can be observed that thecavity 402 is formed on the bottom of a hollow 462 destined to house thecap 432; on the wall of said hollow thejoint 482 for thetooth 442 of thecap 432 is formed. - Figure 6 shows another execution variant; the
spacer 503 is provided on the end destined to the connection with thebody 2 with a T-shaped extension 513. The hollow 512 formed on thebody 2 is equipped on its bottom with acavity 502 complementary to the T-shaped extension 513; theround cap 532 is introduced onto the hollow 512, thetoothed protuberances 542 of said round cap being inserted into thehousings 552. Thespacer 503 is located into the groove 522. - Also the execution variant of figure 7 provides for a connection of the
spacer 603 carried out on thebody 2 of the mask; in this case, too, the body shows on its side a hollow 612 on whose bottom twocavities 602 are obtained, into which will be introduced thestrips 613 of thespacer 603, on the ends of which theprotuberances 623 are formed. Similarly to what has been previously described, the hollow 612 is provided with acap 632 whosetoothed protuberances 642 are engaged with suitable housings formed in said hollow. Thestrips 613 of thespacer 603 are placed into thegrooves 622. - The working of the mask according to the present invention will be evident from the following. As previously mentioned, one of the disadvantages of the mask carried out according to the known technics is the difficult adjustment of the strap tension, substantially due to the elasticity of the band-shaped element which undergoes such adjustment. In the mask according to the present invention the adjustable band-
shaped element 203 does not undergo any strain due to tension, the latter being completely unloaded on the spacers made of elastomeric material. - The spacers can be made of the same material as the face 1 and as one piece together with it; the
groove 102 of the body allows their passage outside thebody 2 of the mask, and said groove is within theframe 112. - The connection of the spacers to the sides of the face 1 can also be obtained by introducing the ends of said spacers, said ends being suitably shaped, into cavities obtained in the
body 2, connected to said face 1. The forms of embodiment shown in figures 2 to 7 and previously described carry out various connection variants of this kind. In all the variants a cap is provided, said cap allowing the fixation of the spacer end to thebody 2. The variant in figures 2 and 3 shows a better distribution of the tension load on thebody 2, whereas the variant in figures 4 and 5 allows, thanks to the flaring of thegroove 422, a certain oscillation angle of thespacer 403. - Anyway, all the execution variants of figures 2 to 7 shows the indubitable advantage, with respect to the form of embodiment of figure 1, of allowing the replacement of the spacer, if damaged or worn out, without replacing the whole mask.
