Description

TITLE

Safety device for a fire extinguisher

FIELD OF THE INVENTION

[0001] The present invention relates to the field of safety. Particularly, the present invention relates to the field of fire safety. More particularly, the present invention relates to the use of fire extinguishers. Even more particularly, the present invention relates to a safety device for a fire extinguisher.

BACKGROUND TO THE INVENTION

[0002] Any reference to background art herein is not to be construed as an admission that such art constitutes common general knowledge in Australia or elsewhere.

[0003] Uncontrolled fires have the potential to cause a significant amount of damage and safety concerns in a short period of time. There are devices that can assist in putting out a fire. For instance, fire extinguishers and fire blankets provide a means of putting out or at least controlling a fire.

[0004] Generally, or broadly, a fire will double in size every 30 seconds when left unchecked. As such, it is of utmost importance that once a fire has been noticed that it be extinguished as soon as possible. Fire extinguishers provide a quick means of controlling or putting out a fire.

[0005] Fire extinguishers are ambidextrous and can be utilized by any person regardless of their ‘handedness’. Typically, all fire extinguishers are provided with a safety pin to ensure that the fire extinguisher is not accidentally discharged. Shown in FIG 1 is a prior art safety pin 10 utilized with a fire extinguisher 30. The safety pin 10 is inserted through aligned apertures of the handle to ensure that the handle is not pressed. The safety pin 10 comprises an elongate member 11 which is inserted through the apertures to prevent accidental actuation of the fire extinguisher. Additionally, a further deterrent in the form of tie 20 is utilized to prevent the pin from accidentally being released. The tie 20 is designed to break under a predetermined tension so that the pin 10 can be removed from the fire extinguisher.

[0006] As shown in FIG 1 , the pin 10 comprises a ring 12 which assists the user in pulling out the pin 10. However, a problem with the removal of the pin is that it must be removed from the fire extinguisher in accordance with the side the ring 12 is located. As such, the pin 10 will need to be removed by either the right hand or left hand depending on the orientation thereof (e.g., a pin inserted in the right-hand side, will need to be removed/pulled from the right side; and vice versa). The orientation of the pin 10 is usually determined by the technician or serviceperson who installed it.

[0007] Typically, a user will pick up the fire extinguisher with their favoured hand, and once this is performed, the pin has to be pulled to allow the fire extinguisher to be activated via the squeezing of the handle. If the pin is required to be pulled from that same side that the preferred hand has picked up the fire extinguisher then this makes the operation of pulling this pin, especially with the added weight of the fire extinguisher, extremely awkward and hazardous. Additionally, this may also require more time and this is unfavourable when dealing with a fire.

[0008] It would be advantageous to address one or more of the above issues and/or to at least provide the consumer with a commercial alternative.

DETAILED DESCRIPTION OF THE INVENTION

[0035] Embodiments of the present invention reside primarily in a safety device. Accordingly, the device, system and/or method steps have been illustrated in concise schematic form in the drawings, showing only those specific details that are necessary for understanding the embodiments of the present invention, but so as not to obscure the disclosure with excessive detail that will be readily apparent to those of ordinary skill in the art having the benefit of the present description.

[0036] In this specification, adjectives such as first and second, above and below, and the like may be used solely to distinguish one element or action from another element or action without necessarily requiring or implying any actual such relationship or order. [0037] Words such as “comprises” or “includes” are intended to define a nonexclusive inclusion, such that a system, method, device, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed, including elements that are inherent to such a system, method, device, or apparatus.

[0038] As used herein, the term ‘about’ means the amount is nominally the number following the term ‘about’ but the actual amount may vary from this precise number to an unimportant degree.

[0039] As used herein, the term ‘fire extinguisher’ refers to a portable device that discharges a substance (such as water, foam, gas or other material) to extinguish a fire.

[0040] As used herein, the term ‘safety device’ can be used interchangeably with ‘anti-discharge device’. The safety device prevents accidental operation of a fire extinguisher. Preferably, the safety device can be reused.

[0041] As used herein, the term ‘handle’ in relation to a fire extinguisher refers to a fire extinguisher handle that comprises two parts: a top handle and a bottom handle. The bottom handle is usually a carry handle and is fixed whereas the top handle is squeezable to actuate the fire extinguisher. The apertures mentioned herein in relation to the fire extinguisher handle may be located in both handles and a safety pin inserted therein prevents actuation or pivoting of the top handle and thus prevents actuation of the fire extinguisher. In one embodiment, the fire extinguisher mentioned herein only has the apertures in the bottom handle. Suitably, a first aperture is located on one side of the handle and the second aperture is located on an opposing side of the handle. Preferably, the first aperture and second aperture are aligned.

This alleviates the problem associated with awkwardness and hazardousness of present safety devices and removes at least one impediment of quick actuation of a fire extinguisher. [0043] In a first aspect, although it need not be the broadest or only aspect, the invention resides in a safety device for a fire extinguisher. The safety device comprises a pulling section having a first end and a second end, a first arm adapted to engage a first aperture of a handle of the fire extinguisher, and a second arm adapted to engage a second aperture of the handle of the fire extinguisher. The first arm is connected to the first end, and wherein the second arm is connected to the second end.

[0044] FIG 2 shows an embodiment of the present safety device. The safety device 100 comprises a pulling section 110 have a first end 111 and a second end 112. The safety device 100 comprises a first arm 120 and a second arm 130. The first arm 120 is connected to the first end 111 of the pulling section

110. In an embodiment, the pulling section 110 is adapted to engage one or more fingers of a user. In some embodiments, the pulling section 110 is curved. In one embodiment, the first arm 120 is substantially perpendicular to the pulling section 110. In an embodiment, the first arm 120 extends away from the first end

111. The second arm 130 is connected to the second end 112 of the pulling section 110. In one embodiment, the second arm 130 is substantially perpendicular to the pulling section 110. In an embodiment, the second arm 130 extends away from the second end 112. In one embodiment, the first arm 120 is substantially parallel to the second arm 130.

[0045] The first arm 120 and second arm 130 are adapted to engage apertures of a handle of a fire extinguisher. The distal end 122 of the first arm 120 comprises an extension 123 that is adapted to engage an aperture of the handle of the fire extinguisher. That is, the extension 123 fits in the aperture. In one embodiment, the extension 123 is suitably a conical or frustoconical shape. The distal end 132 of the second arm 130 comprises an extension 133 that is adapted to engage another aperture of the handle of the fire extinguisher. That is, the extension 133 fits in the aperture. In an embodiment, the extension 133 is suitably a conical or frustoconical shape. The extensions extend towards one another from their respective arm. In one embodiment, the first arm 120 and second arm 130 are biased towards one another.

[0046] The extensions, when engaged with the aperture of the handle of a fire extinguisher, prevents actuation of the fire extinguisher. In one embodiment, each extension independently engages a respective aperture.

[0047] The distal end 122 of the first arm 120 may further comprise a first aperture 124. The distal end 132 of the second arm 130 may further comprise a second aperture 134. The first aperture 124 and/or the second aperture 134 are adapted to receive an anti-tampering device that prevents the safety device 120 from being accidentally released from the apertures and thus fire extinguisher.

Respective notches are generally centrally located in their respective arm.

[0049] The notches 125 and 135 suitably abut each other to form an abutting structure similar to a knuckle connection. This knuckle connection facilitates reaction to when a force is applied to the pulling section. In this regard, as the pulling section is pulled by a user the portion of the first arm and second arm proximate the pulling section deflects inwardly. That is, as the pulling section is pulled, the portion of the respective arm between a respective notch and the proximal end of the respective arm deflects inwardly. As a result of this inward deflection, the distal end of the respective arm (that is, the portion of the arm between the notch and the distal end) deflects outwardly. This assists disengagement of the extension with the apertures of the fire extinguisher.

[0050] In one embodiment, the safety device is formed of a flexible material and/or semi-flexible material. In one embodiment, the safety device is formed of plastic or polymer. A non-limiting example of the material in which the safety device is formed is polypropylene. Polypropylene provides sufficient strength and flexibility to the safety device.

In another embodiment, the distal end 132 of the second arm 130 may be flexed inwardly. That is, the second arm 130 comprises an inwardly flexed distal end. The person skilled in the art will appreciate that the inwardly flexed distal end assists in maintaining the extension in the apertures of the handle. In use, the arms wrap or enclose the handles of the fire extinguisher from above. In this regard, the arms extend around the handle from the outside to engage the apertures. That is the safety device engages the apertures of the handle from the outside in.

[0053] Shown in FIGs 3 and 4 is an embodiment of the safety device 100 engaging a fire extinguisher 300. As shown, the extensions engage the apertures of the handle and prevent actuation of the fire extinguisher. The extension from each arm engages separate apertures of the handle and this allows the arm to extend above the handle. In use, the pulling section is positioned above the handle.

[0054] This orientation allows the safety device to be removed from the apertures by simply pulling on the safety device from above the fire extinguisher. This orientation allows the user to use either hand or fingers thereof to pull on the pulling section of the safety device and addresses the handedness issue above. It will be appreciated this results in other advantages such as addressing the awkwardness and hazardousness of removing the safety device and also allows the user to actuate the fire extinguisher much quicker by facilitating removable of the safety device.
