Definitions

  • the present invention relates to fire extinguishers and in particular to fire extinguisher safety mechanisms.
  • Fire extinguishers frequently include a safety mechanism which prevents accidental discharge of the extinguisher.
  • One such mechanism comprises a pin which extends through the handle of the extinguisher.
  • the pin has a handle at one end which can be pulled by a user when he or she wishes to use the extinguisher. The pulling action breaks a part of the pin allowing it to be withdrawn from the extinguisher handle and allowing the extinguisher then to be used. The broken pin also indicates that the extinguisher has been used.
  • An example of such an extinguisher is disclosed in US-A-3844356 .
  • the end of a pin remote from the pin handle is weakened such that when it is pulled from the extinguisher it breaks, allowing an indicator member to fall away. This indicates that the extinguisher has been used.
  • This type of design has been used by the Applicant for some 20 years.
  • a problem with such designs is that the pin handle projects from one side of the extinguisher body, i.e. it is a "handed" arrangement which may be inconvenient for a user.
  • a further problem is that the pin breaks in tension which may make construction of the pin more difficult or breaking of the pin more difficult.
  • the present invention seeks to overcome or at least mitigate the above problems.
  • GB 2322298 A discloses a fire extinguisher safety mechanism having the features of the preamble of claim 1.
  • JP S50 59894 U discloses an indicator for a fire extinguisher safety mechanism.
  • the present invention provides a fire extinguisher safety mechanism.
  • the mechanism as set forth in claim 1.
  • the user pulls a release member lengthwise from between the handles. Pulling the release member in this manner will cause the shank of the indicator member to shear, allowing the release member to be removed from between the handles. One of the handles can then be moved relative to the other to operate the extinguisher. The indicator member will no longer be retained and will simply fall away indicating that the extinguisher has been used. As its shank has been sheared, it cannot be used again.
  • the head of the indicator member may be relatively thin and may for example be disc like. It may be circular in shape or have any desired shape, for example a polygonal shape.
  • the head may carry an inscription, for example "OK", to indicate that the extinguisher has not been used.
  • the indicator member may be brightly coloured. It may be made from a fluorescent, phosphorescent, luminescent or other 'glow in the dark' material.
  • the colour of the indicator may be varied to, for example, indicate its year of manufacture or servicing of the extinguisher, thereby giving the user an indication of the period in which the extinguisher has not been operated. Up to 20 wt% of a coloured and/or luminous additive may be added to the material of the indicator.
  • the indicator member may be moulded from a plastics material, for example a polystyrene material.
  • the material should desirably be chosen such that the shank of the indicator member shears without excessive strain, i.e. such that it does not stretch excessively. It the material stretches, it will break in tension rather than in shear which is undesirable since the force required to break the shank would typically be twice as high in tension as in shear.
  • a desirable breaking force in some applications is less than 100N, for example below 80N.
  • regrind (particularly of the same material of the virgin material) may be added to the virgin material. This reduces the strength of the virgin material. In one example, between 2-10 wt% regrind, more narrowly 4-6 wt%, for example 5% regrind may be used.
  • a material which has proven particularly suitable is EDISTIR N1840, with 5 wt% EDISTIR N1840 regrind.
  • the indicator member head may be configured to be received by a complementary area provided on the extinguisher head, more particularly an area on the movable handle of the extinguisher. That area may carry an inscription such as "USED" which becomes visible once the indicator member head has fallen away, thereby indicating that the extinguisher has been used.
  • the inscription may be embossed, printed or otherwise provided on the extinguisher head.
  • the shank may be provided with one or more areas of weakness. This area of weakness may be in an intermediate region of the shank.
  • the shank is provided with a through hole which effectively reduces the thickness of the shank.
  • a through hole may be provided in a waisted region of the shank. This not only reduces the force necessary to shear the shank but also to improve flow of material in the mould during the moulding of the indicator member.
  • the shank may be stepped in order to provide a first region for engaging in the aperture provided in the extinguisher head and a second region, smaller in cross section than the first region, for engaging in the aperture provided in the release member.
  • a proximal portion of the shank adjacent the head may taper towards the distal end of the shank. This avoids a columnar shank which potentially could be reinserted in the aperture in the extinguisher head after use, which is undesirable.
  • the resilient retaining means provided on the distal end of the shank may be barb-like, for example formed on the ends of flexible legs formed by a slot in the distal end of the shank. The barbs prevent the indicator member being withdrawn from the release member once the indicator member has been inserted.
  • the distal end of the shank may have a profile which is at least in part complementary to that of the aperture in the distal end of the release member. This is advantageous in that it helps locate the indicator in the release member and reduces twisting of the shank as the release member is withdrawn, thereby reducing the chances of the shank breaking in tension rather than in shear.
  • the lateral surfaces of the flexible legs of the retaining means may be formed as flat surfaces, particularly parallel flat surfaces, to cooperate with complementary surface in the aperture in the release member.
  • Alignment means may be provided to align the indicator member in an appropriate orientation on the extinguisher, so that, for example, any inscription is easily readable by a user.
  • the rear surface of the head of the indicator member is provided with a formation, for example one or more projections which engages with a corresponding formation on the extinguisher.
  • the rear surface of the head is provided with a rib which engages under the lower edge of the handle to which the indicator member is mounted.
  • the indicator member is broken and, once the extinguisher is re-charged, must be replaced.
  • the proximal end thereof may comprise an aperture through which a user may place one or more fingers to pull the release member from between the extinguisher handles.
  • the distal end of the release member may be provided with a clip for engaging a part of the extinguisher handle or a part of the extinguisher valve mechanism to assist in retaining the release member in position. This may take some load off the shank of the indicator member in the event of a force being applied accidentally to the release member.
  • the aperture in the distal end of the release member may be at least in part complementary in shape to the distal end of the indicator shank.
  • the distal end of the release member may be provided with a boss, offset from the main plane of the release member.
  • the boss is provided with the aperture for receiving the shank of the indicator member. This may allow the shank of the indicator member to be shorter in length, leading to improved strength and stability. It may also prevent or reduce external access to the shank.
  • the release member is shaped to be received between the fixed and movable handles of the fire extinguisher operating mechanism. Both handles may be provided with longitudinally extending formations for example grooves or ribs to locate the release mechanism. The release member may then be provided with complementary formations.
  • the release member may be moulded from a plastics material such as polypropylene and it may be brightly coloured, luminescent, fluorescent etc. as the indicator member. It may be formed from different colours to reflect the type of extinguishing material held in the extinguisher, e.g. water, foam of powder. Up to 20 wt% of a coloured and/or luminous additive may be added to the material of the indicator.
  • the invention also extends to a fire extinguisher including a safety mechanism as discussed above.
  • the aperture for receiving the shank of the indicator member is provided on the movable handle of the extinguisher.
  • a fire extinguisher 2 comprises a head 4 having a ferrule 6 for the attachment of a hose (not shown).
  • the head 4 comprises a fixed handle 8 and a movable handle 10 which is pivotably mounted to the fixed handle 8 about a pivot (not shown) in a known manner.
  • downward movement of the movable handle 10 presses on a actuating pin (not shown) which opens a valve to release fire suppressant, e.g. water, foam or powder through the head 4 and ferrule 6.
  • fire suppressant e.g. water, foam or powder
  • the safety mechanism 14 comprises a release member 16 and an indicator member 18.
  • the release member 16 is moulded from a plastics material, e.g. polypropylene, and is elongate. It is received between the movable and fixed handles 8, 10. As can be seen from Figures 2 to 4 , the release member 16 has a generally planar web 20 with a relatively narrow flange 22 provided around its periphery, in particular along is upper edge 24, and a relatively wide flange 26 provided along its lower edge 28. A rib 30 projects downwardly from the relatively wide flange 26.
  • a plastics material e.g. polypropylene
  • the relatively narrow flange 22 is received within a groove 32 provided on the lower surface 34 of the movable handle 8, and the rib 30 received in a groove 36 provided on an upwardly facing surface 37 of the fixed handle 10.
  • the interengagement of the flange 22 in groove 32 and rib 30 in groove 36 provides lateral support for the release member 16.
  • the proximal end 38 of the release member 16 is provided with a circular opening 40 through which a user may insert one or more fingers.
  • the middle section 42 of the web 20 is provided with arrow like openings 44 which indicate to the user the direction of operation of the release member 16.
  • the distal end 46 of the release member 16 comprises a resilient clip 48 which in use engages around a post provided in the movable handle 8.
  • the boss 50 has a forwardly projecting flange 52 the distal end 54 of which is provided an opening 56.
  • the opening 56 is generally circular in shape, but with straight sides 58.
  • the opening 56 receives the indicator member 18, which is described with reference to Figures 8 to 10 .
  • the indicator member 18 is of moulded from a plastics material such as polystyrene.
  • the material may be EDISTIR N1840 with 5 wt% regrind. It may be brightly coloured and may be fluorescent or phosphorescent.
  • the head 60 comprises a relatively thin, disk-shaped head 60 and a shank 62 projecting from the rear surface 64 of the head 60.
  • the head 60 may of course have any convenient shape, for example polygonal.
  • the front surface 66 of the head 60 is provided with a recessed inscription 68 ("OK" in the illustrated embodiment) which will be seen by a user when the indicator member 18 is in situ.
  • the rear surface 64 of the head 60 is generally planar for engaging and covering a complementary area 70 of the movable handle 8.
  • this area 70 bears an inscription 72, in this embodiment "USED", so that when the area 70 is exposed, the user will know that the extinguisher has been used. Of course some other wording may be used, for example "used” in other languages.
  • That area 70 also includes an opening 71 for receiving the shank 62 of the indicator member 18.
  • the rear surface 64 of the head 60 also comprises a rib 74 which in use engages under a portion of the lower edge 76 of the movable handle 8 to assist in the orientation of the indicator member 18 so that the inscription 68 is the correct way up.
  • the shank 62 is provided with a slot 78 at is distal end 80, thereby defining two resilient legs 82.
  • Each leg 82 is provided with a barbed tooth 84 at its distal end.
  • the lateral surfaces 86 of each leg 82 are formed as flat surfaces for engagement with the sides 58 of the opening 56 in the distal end of the release member 16. The surfaces 86 stand proud of the surrounding surface, as can be seen most clearly from Figure 11 .
  • the upper and lower surfaces 88 of the legs 82 are generally circular in section and of a diameter smaller than the circular sections of the opening 56.
  • the shank 62 has a tapering proximal section 90 and a transversely waisted intermediate section 92.
  • An opening 94 is provided through the intermediate section 92 to provide a well defined area of weakness in the shank 62.
  • the dimensions of the waisting and opening 94 are chosen such that the shank can break in shear under an applied force of less than 100N.
  • the maximum diameter of the proximal and intermediate sections 90, 92 is smaller than the diameter of the opening 71 provided in the area 70 of the movable handle 8 to allow the shank 62 to be received therein.
  • the release member 16 is inserted longitudinally into position between the handles 8,10.
  • the flange 22 and the rib 30 provided on the release member 16 and the grooves 32, 36 formed in the handles 8, 10 guide the release member 16 appropriately.
  • the release member 16 is pushed into the space between the handles 8, 10 until the clip 48 engages with the valve pin. In this position, the opening 56 at the distal end of the release member 16 is aligned with the opening 71 provided in the movable handle 10.
  • the relatively wide flange 26 of the release member 16 generally follows the contour of and covers the upper surface 37 of the fixed handle 8.
  • the indicator member 18 can then be mounted.
  • the shank 62 of the indicator member 18 is pushed through the opening 71 in the movable handle 8 and the aligned opening 56 in the release member 16.
  • the resilience of the legs 82 of the shank 62 allow the barbed teeth 84 to deflect inwardly as the shank 62 is pressed in, and then spring back when the teeth 84 have passed through the openings 71, 56 preventing the indicator member 18 from being withdrawn through the openings.
  • the flat lateral surfaces 86 of the legs 82 engage closely with the straight sides 58 of the opening 56. This will help prevent twisting of the shank 62 as the release member is pulled out.
  • the user pulls the release member 16 from between the handles 8, 10 in the direction indicated by the arrow openings 44.
  • the pulling action causes the weakened intermediate section 92 of the shank 62, which is within the opening 56 in the release member 16, to shear, allowing the release member 16 to be withdrawn.
  • the release member 16 pulls the distal end 80 of the shank 62 away with it so that it does not interfere with operation of the extinguisher.
  • the head 60 of the indicator member 18 simply falls away, no longer being retained by its shank 62. The extinguisher 2 can then be used in the normal way.
  • a new safety mechanism 14 may be installed.
  • the relatively robust release member 16 is not damaged in use and so may be re-used.
  • a new indicator member 18 will have to be provided.
  • the tapering of the proximal portion 90 of the shank 62 of the indicator member 18 means that the used indicator member 18 cannot simply be pushed into the opening 71 in the handle 8, as it will simply fall out. This would be undesirable since a user would then not be able to determine with certainty whether an extinguisher had been used or not.
  • the indicator member 18 is a moulding, it is relatively inexpensive to replace.
