A TRADESMAN'S MASK TECHNICAL FIELD [00011 The present invention relates to masks and, more particularly, to a mask to protect the face of a tradesman. BACKGROUND ART 100021 Tradesmen typically use protective eyewear to protect their eyes whilst engaged in the course of their trade. Protective eyewear may include glasses, goggles and full-face masks. A problem with glasses is that whilst they may protect eyes from directly oncoming objects, they do not protect eyes from objects approaching from above or below the glasses. Goggles or full face masks may overcome this problem. However, they are uncomfortable to wear for long periods. Goggles fog in the presence of perspiration. Goggles also cause pressure on the eyes and restrict the field of vision of the tradesman. Glasses and full-face masks often move on the head of the tradesman as the tradesman tilts his or her head, such as when painting a roof or examining the underside of a vehicle. The movement of the glasses and full-face masks is dangerous as it may allow objects to bypass the eye visor and damage the eyes of a tradesman. Neither goggles nor full-face masks allow air to circulate around the eyes. 100031 There is a need for a device which protects the head of a tradesman, is comfortable to wear for long periods, stays in the same position even when the tradesman's head is tilted, protects the eyes from objects approaching from above and below the tradesman's head and allows air to circulate around the eyes to avoid fogging. Furthermore, there is a need for a device which protects not only the eyes of a tradesman, but also the ears, nose, mouth and hair, whilst fulfilling the needs referred to above. SUMMARY OF INVENTION 100041 The object of the present invention is to overcome or at least substantially ameliorate the aforementioned problems. [00051 According to the present invention, there is provided a tradesman's mask to protect the face of a tradesman, the mask comprising: a resilient head mask portion for location relative to at least a portion of the tradesman's head; and an eye protection assembly having conjoined lenses attached relative to the head mask portion so as to at least impede the entry of objects behind the eye protection assembly. 100061 The conjoined lenses may comprise a single unitary lens for both eyes, or two lenses conjoined by a frame. The frame of the lenses may be attached relative to the head mask portion. [00071 Preferably, the resilient head mask portion is made of nylon. 10008] The mask may be adapted to be removably connected to another mask. More preferably, the mask has a perforated edge enabling it to be removably connected to another mask. [00091 In a preferred form of the invention, the mask also comprises one or more sweat pads for absorbing sweat. More preferably, the sweat pad is located over the forehead of the tradesman. 10010] It is preferred that the eye protection assembly comprises a rigid transparent material. However, the eye protection assembly may also comprise a flexible transparent material. 100111 In a preferred embodiment of the invention, the mask is adapted to surround the entire head of the tradesman so as to protect his or her eyes, hair, nose, mouth and ears. However, the mask may be adapted to surround only a portion of the tradesman's head around the eye protection assembly. 100121 The mask may comprise a filter located over the mouth and/or nose to protect tradesman against dust, airborne particles and other objects. [00131 In some embodiments of the invention, the mask may be connected to a respirator.

DETAILED DESCRIPTION OF EMBODIMENTS 100251 Figure 1 shows a mask 10 according to a first embodiment of the present invention. The mask 10 covers the entire head of the tradesman 12. The mask 10 includes a resilient head mask portion 14 and an eye protection assembly 16. The protection assembly 16 includes conjoined lenses 18 and 20 to protect the eyes of tradesman 12. The mask 10 is protects not only the eyes of a tradesman 12, but also the ears, nose, mouth and hair. The mask 10 may be made of nylon, which is a lightweight, permeable and resilient material. The head mask portion 14 holds the protection assembly 16 in position on the head of the tradesman 12. 100261 The mask 10 is comfortable to wear for long periods, stays in the same position even when the head of the tradesman 12 is tilted, protects the eyes from objects approaching from above and below the eye protection assembly 16 and allows the air to circulate around the eyes to avoid fogging of the lenses 18 and 20. 100271 Figure 2 shows the mask 10 in use by the tradesman 12 working underneath a car 22. Debris 24 is shown emerging from the car 22 and approaching the head of the tradesman 12 from above the eye protection assembly 16. Because the head mask portion 14 of the mask 10 is connected to the eye protection assembly 16, the debris 24 cannot access the gap between the head of the mechanic 12 and the eye protection assembly 16. Thereby, the mask 10 is able to protect the eyes of the tradesman 12. Because the head mask portion 14 of the mask 10 is made of a permeable material, such as nylon, air may flow around the face of the tradesman 12 and allow sweat to evaporate. [00281 Figure 3 shows the mask 10 in use by the tradesman 12, wherein debris 26 approaches the tradesman 12 from beneath the protection assembly 16. The mask 10 impedes the entry of the debris 26 underneath the eye protection assembly 16 because the head mask portion 14 is directly connected to the protection assembly 16. [00291 Another embodiment of the invention is shown in figure 4. In this embodiment, the mask 10 features an ear guard 28 to protect the ear from the debris, dust, vapours and substances such as paint. The ear guard 28 may comprise several layers of a resilient head mask portion such as nylon, a thicker synthetic polymer (such as ballistic nylon), Gore-TexIM or any other protective material. [0030] The embodiment of the mask 10 shown in figure 5 has a flexible eye protection assembly 30 and an air filter 32 incorporated into the tradesman's mask 10. The flexible eye protection assembly 30 could be used in conjunction with safety goggles or prescription lenses of the tradesman 12. The filter 32 protects the tradesman against dusts and particulates encountered during construction or cleaning activities, such as dusts from drywall, concrete, wood, fiberglass, silica (from ceramic or glass production), or sweeping. The filter 32 may also protect the tradesman against vapours, fumes, mould spores and germs that can cause lung diseases, such as asthma and bronchitis. The filter 32 could be substituted for respiratory protective equipment, which may be connected to a filtered air intake. 100311 The mask 10 shown in figure 6 has a membrane 34 which covers the nose, mouth and ears of the tradesman 12 to impede the access of particles into the orifices of the tradesman 12. Figure 7 shows an embodiment of the mask 10 wherein the resilient head mask portion 14 only covers the region around the eye protection assembly 16, and the nose and ears of a tradesman 12. Figure 8 shows an alternative embodiment of the mask 10, wherein the head mask portion 14 only covers the nose and region surrounding the eye protection assembly 16 of the tradesman 12. The eye protection assembly 16 shown in figure 8 has a pair of arms 36 that support the eye protection assembly 16 on the ears of the tradesman 12. [00321 Figure 9 shows yet another embodiment of the invention, wherein the mask 10 includes a sweat pad 38 connected to the head mask portion 14. The sweat pad 38 is positioned on the forehead of the tradesman 12 and absorbs perspiration. The mask 10 may have a plurality of sweat pads spread around the head of the tradesman 12. [00331 Another aspect of the invention is that a series of masks 10 may be removably connected along a perforated edge 40 and dispensed on a roll 42. The mask 10 also includes a sealed end 44 and an open end 46. The head of the tradesman 12 may be inserted through the open end 46 and the eyes of the tradesman 12 may be aligned with the transparent eye protection assembly 16. Other methods of dispensing the mask 10 are within the scope of the present invention and may include for example, a box containing a pile of masks which can be dispensed in a manner similar to the manner in which tissues are commonly dispensed. In other embodiments of the invention, the mask may be dispensed in a roll and manually cut into sections by a tradesman, whereupon the tradesman may a tie a knot to close the mask 10. 100341 A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.
