DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device making it possible to orientate oneself when swimming on one's back.
In general, swimmers twist their head awkwardly from time to time in order to steer.
In other cases, they turn over, returning to swimming on their front, to see directly.
FR-A-2 630 653 makes known swimming goggles in which a small mirror is incorporated so as to allow the swimmer on his back to observe the environment in the direction of swimming. That being the case, the extremely small size of the mirrors and their position give visual comfort which is entirely inadequate because the swimmer has to look toward his nose. Furthermore, as the mirrors are provided inside the goggles, they are liable to mist up and further impede vision.
This document also proposes a mirror fixed close to the eyes of the swimmer by a relatively complicated system relying on the use of an elastic collar, a support on the nose and hooking behind the ears. This alternative form is disadvantageous as regards comfort and also as regards the quality of the vision.
DE-U-89 11 489 also makes known a device according to the preamble of claim 1. This known device is also disadvantageous in that it requires an elastic collar which encircles one's head, which is uncomfortable and runs the risk of shifting during swimming.
The device according to the invention aims to overcome these drawbacks.
Thus, the invention proposes an orientation aid device for swimming on one's back, characterized in that it comprises a support, an end piece provided at one end of the support and enabling the support to be held in the mouth of the swimmer, and a location-identification means fixed to the support mirror adjustably. parts of the support. articulated link is capable of converting the support into a snorkel for swimming on one's front. two first tabs integral with the two ends of the collar, and a second tab integral with the mirror and capable of being clamped between the first tabs using a clamping means. mouth, and the location-identification means is mounted on the tubular support removably.
Other aspects, objects and advantages of the present invention will become clearer from reading the following detailed description of preferred embodiments thereof, given by way of nonlimiting example and made with reference to the attached drawings, in which:
FIG. 1 is a perspective view of a device according to a first embodiment of the invention,
FIG. 1a is a diagrammatic side view of the device in use,
FIG. 2 is a perspective view of a device according to a preferred embodiment of the invention,
Referring first of all to FIG. 1, a device has been represented which includes a mouthpiece 10 extended by a bent tubular support 20 to which a mirror 30 is fixed in the opposite end region to the end piece 10. This fixing is achieved for example by bonding or welding.
When a swimmer is swimming on his back, this device is intended to be kept generally vertically above the swimmer's face, merely using the mouth of the swimmer, the inclination of the mirror 30 given by the intermediate bend in the tube 20 allowing the swimmer to be able to see in the direction in which he is traveling.
In the current example, the mouthpiece 10 is made in the form of an elastomeric sleeve tube 11, a few millimeters thick, tightly surrounding the free end 20a of the tube 20. By way of preference, to favor holding in the mouth, the tube 20 is ovalized in the region of its end 20a.
The height of the mirror 30 makes it possible permanently to keep one's objective in sight despite the wiggling of the body and the movements of the head. Furthermore, the tube 20, which is hollow, advantageously allows air to be drawn in from a certain distance above the water level. In this way, there is no risk of the splashing caused by swimming disrupting breathing. Furthermore, in the case of swimming in a swimming pool, and more specifically with highly chlorinated or otherwise treated water, since the air is taken from a substantial distance above the water surface, it is more pure.
