Visual aid
WO 2001042847 A1
Abstract
A visual aid (10) consists of a pair of lenses (15) in frames (16) mounted on arms (14) extend laterally from a headset (11). The headset (11) is in the form of a support unit (12) adapted to be supported around the upper part of the head of a person, thereby eliminating pressure on the nose. The support unit is a resilient headband (12) to each end of which is attached a headphones ear pad (13). The lenses (15) are adapted optically to assist the vision of the wearer of the visual aid (10) as in the case of conventional spectacles, or to reduce the glare from sunlight or other bright source of light, or are of clear plane material to serve as protection of the eyes of the wearer from water, the air or airborne matter. An audio lead (17) connects the ear pads (13) to an audio unit (18) that has a battery pack (27) providing power to a radio, cassette or disc player (28). A controller (22) controls the signal from the audio unit 18 to the ear pads (13).

Description  (OCR text may contain errors)

VISUAL AID

This invention relates to visual aid, and in particular to spectacles or goggles

A pair of spectacles or goggles usually has one or more of three purposes, to improve the vision of the wearer, to reduce glare from the sun or other bright source of light and/or to protect the eyes from water, the air or airborne matter There are many designs of spectacles and goggles currently available, but the differences between the different designs are usually cosmetic, i e they are intended to enhance the appearance of the wearer Most of these designs comprise a lens arrangement, i e a pair of lenses or a single lens, which may be mounted in a frame or on a support, with the frame or support retained on the face of the wearer by means of arms which either grip the side of the head or wrap around the wearer's ears Alternatively a resilient strap may be attached to the lens arrangement, frame or support and placed around the back of the head of the wearer The weight of the lens arrangement and frame or support is usually taken by means of a shaped portion of the frame or lens arrangement resting on the bridge of the wearer's nose

One problem is that of listening to headphones whilst wearing such visual aid, since the arms or strap and the headphones tend to interfere with each other, particularly if the wearer wishes to remove and replace the visual aid or the headphones at frequent intervals In addition the weight of the visual aid on the nose can cause discomfort and even soreness over a penod of time, particularly if the wearer does not wear a visual aid on a regular basis

It is an object of the present invention to provide a visual aid that avoids the abovementioned disadvantages

The invention provides a visual aid comprising a lens arrangement mounted to extend laterally from a headset arrangement, the headset arrangement comprising a support unit adapted to be supported around the upper part of the head of a person

The visual aid may comprise a pair of lenses The lenses may be adapted to improve the vision of the person, and/or to reduce glare from the sun or other bnght source of light and/or tp protect the eyes from water, the air or airborne matter Each lens may be supported by a respective arm that is attached to the support unit The support unit may comprise a band formed to extend around the top of the head The band may be resilient Each arm may be pivotally attached to the support unit, and may be pivotally attached to its respective lens Each arm may be formed of a plurality of parts, each part pivotally attached to an adjacent part. Each arm may be of a resilient material, and may be of a metal or plastics material.

Arms on opposed sides of the support unit may be resiliently biased towards each other.

The headset arrangement may comprise a pair of headphones. In this case the visual aid may also comprise an audio system. An audio device may be connected to the headphones, and the audio device may be a radio and/or a tape or disc player. The audio device may be adapted to be worn on a belt of the person. The visual aid may comprise a control unit, which may be operable to control the volume and the operating mode of the audio device, e.g. radio/cassette, radio programme.

The control unit may be adapted to be worn by the person, and may be adapted to be worn on the wrist of the person. The control unit may comprise a watch. The control unit may be electrically connected to a power unit, and the power unit may be adapted to be worn by the person. The power unit may be adapted to be worn on the belt of the person, and may be integral with the audio unit.

The invention will now be further described with reference to the accompanying drawings in which:

Fig. 1 is an illustration of one embodiment, and

Fig. 2 is a schematic of the control system

Referring now to Fig 1 there is shown a visual aid 10 which has a head unit 11 consisting of a resilient headband 12 which is worn over the head of a person using the visual aid 10. To each end of the headband 12 is attached a headphones ear pad 13 and one end of an arm 14. At the other end of each arm 14 is a lens 15 mounted in a frame 16. The lenses 15 may be adapted optically to assist the vision of the wearer of the visual aid 10 as in the case of conventional spectacles, or may adapted to reduce the glare from sunlight or other bright source of light, or may be of clear plane material to serve as protection of the eyes of the wearer from water, the air or airborne matter. With such an arrangement there is no pressure on the nose of the wearer.

An audio lead 17 connects the headphones ear pad 13 to an audio unit 18 such as a radio, cassette player and/or disc player, which comprises its own power pack. The audio unit 18 has a clip 19 by means of which it may be worn on a belt around the person's waist. The audio unit 18 has controls 20 by means of which the received signal and/or the volume of the signal received by the headphones 13 may be varied. Alternatively the audio lead 17 may be connected to a separate audio unit 21 such as personal stereo radio/cassette/CD player (Fig. 2) In this case a controller 22 is provided which is adapted to be worn on the person's wrist and is combined with a watch 23 The controller 22 generates infrared signals which are received by a signal receiver 24 connected to one or each of the headphones ear pads 13

Using the controls 25 of the controller 21 , the volume of the signal received by the ear pads

13 may be vaπed

The arms 14 are rotatably attached to the ear pad 13 and headband 12, so as to be positionally adjustable relative thereto as shown by arrow A The arms 14 are also s dable relative to the ear pad 13 and head band 12 as shown by arrows B, such that the lenses 15 may be moved relative to each other in order to place them on the face over the eyes in the most comfortable position for the wearer The arms 14 are preferably made from a polyethylene extrusion to provide springiness to grip the person's face Alternatively or in addition the arms 14 may be resiliency biased towards each other by means of springs 26 The travel of the lenses 15 relative to the ear pads 13 may be up to 15 mm

Refernng now to Fig 2, the audio unit 18 compnses a battery pack 27 which provides electπcal power to a radio, cassette player and/or disc player 28 connected by the audio lead 17 to the ear pads 13 In the alternative arrangement, the audio lead 17 is connected to separate audio unit 21 such as personal stereo radio/cassette/CD player The controls 25 (Fig 1) of the controller 22 create an infra-red (IR) link 29 to the signal receiver 24 to control the volume of the signal received by the headphones 13 The watch 23 may also display the chosen setting Control of the audio unit 21 may be by controls on the unit itself, and/or by the controls 25 of the controller 22

By means of the invention a visual aid is provided which is convenient for home as well as for outdoor use The person wearing the visual aid can move around and perform other activities such as domestic chores, using exercise apparatus, walking, travelling by vehicle or the like The person can also listen to music or other radio programme There is no difficulty expenenced by wearers of spectacles in putting on and removing the spectacles whilst wearing headphones

Other embodiments of visual aid within the scope of the invention will be readily apparent to persons skilled in the art For example the arms 14 may comprise one part as described above or two or more mutually articulated parts Alternatively they may be resiliency deformable to a shape that is suitable for the wearer Instead of the belt clip 19, a belt or strap may be attached to the audio unit 18 The head unit 11 may comprise a hat, for example a baseball cap, instead of the headband 12
