Definitions

  • the present invention is directed towards devices and methods of use of protecting an individual’s face or facial area from particulate matter, which can include the eyes, nose and mouth through the use of directional air flow to create a protective barrier or zone in front of the user.
  • woodworking can create different levels of particular matter from large chips of wood during sawing or planning, as well as fine particulate wood dust from sanding, milling and other finishing work.
  • Large particles of wood chips from sawing are relatively heavy compered to wood dust, their travel is localised to the area in which the activity is conducted.
  • the fine wood particular matter, referred to as saw dust presents a different hazard to wood chips or shavings as wood dust can travel a further distance from where the wood working operation is taking place and once airborne sawdust can be inhaled, where it can build up over time and cause allergic respiratory symptoms mucosal and non-allergic respiratory symptoms.
  • sawdust is a known carcinogen.
  • Sawdust can also accumulate up on the moist surfaces of the eye and the eye area becoming a potential source of eye irritation.
  • plaster to walls can also be hazardous from the handling of bagged dry plaster to the process of smoothing plaster by sanding which can create fine airborne particulate matter that can lead to both respiratory irritations and eye irritations.
  • the application of paint can lead to similar hazards through the creation of fine airborne droplets from spraying that can remain suspended in the air for some time being dispersed over a large area.
  • the installation of insulation can also create an environment high in fine particulate matter in the form of microscopic fibreglass particles that can be inhaled or enter or land on the eye causing considerable irritation.
  • Protective eyewear is commonplace in workplaces where particulate matter is generated.
  • Protective eye shields such as googles are used to protect the eyes from flying particles that might be generated from the action of sawing or grinding metal.
  • Such protective eyewear has limitations however as they are designed to protect the eyes predominately from objects travelling at speed and penetrating the eye and are not designed to mitigate effects of particular matter such as dusts or other fine matter.
  • Goggles usually have a number of air holes located about the frame area to allow some air flow to pass into the area of the googles and reduce condensation. Filter materials may be placed over such holes to attempt to restrict the flow of dust in between the googles and the user’s eyes.
  • Goggles, and similar eye protection have the drawback of not providing any protection to the respiratory paths (nose and mouth) of a user, requiring the use of a face covering such as a dust mask, to help prevent dust inhalation. In some situations full face covering masks incorporating goggles and respiratory protection are used, however these are cumbersome and expensive for many.
  • the present invention seeks to provide a solution to this problem(s) by providing facial area protection using air flow to form a barrier to particulate matter.
  • a device for protecting a face of a user including a frame having at least one air delivery chamber configured to connect to an air supply source, the at least one air delivery chamber directing air from the air supply source though an opening downwards over the face of the user.
  • the at least one air delivery chamber is tapered.
  • the opening is a slit.
  • the frame is tapered.
  • the opening on the at least one air delivery chamber is a plurality of holes arranged in a line.
  • the bridge nose piece includes a hollow chamber to fluidly connect the two air delivery chambers.
  • the opening on the underside of the at least one air delivery chamber includes an air flow guide.
  • the air flow guide projects downwardly from the at least one air delivery chamber and has a longitudinal opening for air to pass through.
  • the air flow guide produces a substantially laminar air flow over the face of the user.
  • the device includes an air supply source.
  • the air supply source includes a powered fan.
  • the air supply source includes a filter means for filtering out particulate matter.
  • the air supply source is a positive air source.
  • the device is shaped to fit over a pair of glasses/goggles.
  • the device includes a frame that includes a lens.
  • the frame includes mounts for attaching a retaining means to retain the device to a user’s head.
  • the retaining means is one of a head band, head strap, earpieces.

  • a bridge nose piece 50 Joining the two frame members 15a and 15b is a bridge nose piece 50, figures 8-11, which includes the bridge 51, arms 52 and nose pads 53.
  • a hollow tube section 55 has apertures 56 into which the protrusions 27 on the first ends 16a, 16b of the frame member 15a, 15b positively engage with to form a snap fit connection.
  • the tube 55 can be hollow to create a fluid connection between the air chambers, to allow air forced into the air delivery chambers to pass from one air delivery chamber into the other air delivery chamber or in the event of there being only a single air supply source connected to only one of the seconds ends 17 of the frame 15, the other second end 17 being blocked.

  • a tube 180 is located about an outer periphery of the air flow guides 150 to provide a conduit to conceal wiring used where a power source (battery) resides on one side of the device, allowing the air supply source on an opposite side to be powered from the one power source.
  • a close up of the area B in figure 14 is shown in figure 15.
  • the air flow guides 150 on the underside 140 of the frame members 110 forces the air flow from the air delivery chambers 170, which act as a plenum chamber, to pass down through the channel 190 and modify the air flow into a more laminar flow of air which passes over the users face. This has the effect keeping the air flow closer to the users face and thus acting in a more effective manner.
  • the same can be achieved by having the opening located on the lateral side of the air delivery chamber, rather than on the underside, to direct the air flow first horizontally, then downwards, in an L-shaped path, over the face of the user. For example the opening exiting the air delivery chamber though a front face of the frame then directing the air downwards over the face of the user.
  • the device 10, 100 is coupled to an air supply source if required, the air supply source may be separately located on the user’s belt or headwear or incorporated into the device itself, and the device fitted to the head of a user.
  • the air supply source Upon activation of the air supply source, air is drawn in through a suitable filter material to restrict passage of particular matter and forced into the openings 20a, 20b of the air delivery chambers 22a, 22b and forced out through the slits 30, 130 downwardly over the users face. Any particulate matter that may be suspended in the atmosphere around the user face is then forced downwardly and away from the eyes/nose/mouth of the user, the directed air stream thus acting as an air curtain or barrier, thus substantially reducing exposure of harmful particulate matter to the user.
  • the present device 10, 100 is lightweight and readily worn, thus increasing compliance by users without adverse effects from heavier, enclosed goggles.
  • the face air mask 10 has a docking area 17 to sit an attached air moving system which allows for air to be passed through the tubes.
  • the tubes 15 also have slits 30 taken from them to allow for air to pass out of the tubes to flow over the face to protect it from foreign objects.
  • the face air mask has an attachment at the end of the tubes, closest to the nose called a bridge and nose pads to make the face air mask sit on the face comfortably, but this can be interchanged to a straight rod but not limited to, to allow for other glasses to be worn.
  • the tubes have an optional attached mould preferably made from a flexible polymer but not limited to, so that prescription or any other choice of glasses can be easily attached.
  • the face air mask is preferably made of a semi flexible polymer, however other materials can also be used. For example a range of metals may also be used to allow for a stronger face air mask, but is not limited to any type of material.
  • the air face mask is made up of multiple parts.
  • a docking area 17 is situated at the rear of the device which allows for an air moving system to pass air into the entrance 20 of the tubes 22.
  • the air moving device is interchangeable to different sizes to be able to release different pressures of air from the slits 30.
  • the tubes 15 maybe connected via a tubed connector 55 that is connected to the top of a bridge 50 which has nose pads 53 to make it comfortable for sitting on the nose.
  • the tubed connector 55 and the bridge 50 may come apart, still keeping the tubes 15 and the tubed connector 55 intact, thus leaving a pair of glasses of your choice to be joint onto the face air mask.
  • the glasses attachment mould 19 would sit on top of the glasses still allowing air to leave the slits 30 to protect the face.
  • the strap holders 18 are attached to the docking area 17 allowing a strap to be attached to the device giving it more stability on the head.
