Description
1 2011221368 10 Feb 2017 PROTECTOR APPARATUS Field of the Invention
The present invention relates generally to apparatus for protecting structures and structural components or members.
Although the present invention will be described with particular reference to protecting rack structures, it will be appreciated that it may be used to protect other types of structures.
Background Art
Protector apparatus are used for protecting structures or structural components or members from being damaged as a result of collisions with objects. For example, such apparatus are often used to protect storage racks which are used for storing goods in warehouses and the like. Such storage racks typically include a plurality of upright posts which support a plurality of beams which in turn support a plurality of shelves. Vehicles such as forklifts, reach trucks and the like are often used to transfer pallets and/or goods to and from the pallets of such storage racks. The upright posts of the storage racks are susceptible to damage as a result of collisions with the vehicles and/or the pallets and/or goods which they are transferring to or from the shelves.
Over the years various types of protector apparatus have been developed. For example, metal guards/protector apparatus which are constructed from steel are either designed to deflect impact loads away from the upright post or the floor slab supporting the post, or they transfer these loads into the upright or the floor slab depending on the way in which the apparatus is attached to the post and/or the slab. Apparatus of this type provide very little impact absorption. They also do not protect the rear of the post which they are supposedly protecting.
An example of a metal guard/protector apparatus is the Dexion™ Smart Guard™ guard/protector apparatus which is the subject of Australian design registration No. 319547, and published Australian patent application No. 2009200245. Another example is Dematic Pty Ltd’s Colby™ Protect-a-Rack™ metal guard/protector apparatus which is disclosed in Australian design registration No. 301237, and Australian innovation patent No. 2009100748. 2 2011221368 10 Feb 2017
Plastic guards/protector apparatus typically absorb impacts, but in order to do this effectively they become cumbersome to fit. Also, they tend to intrude into the product storage areas, thereby reducing minimum clearance requirements between unit loads and rack uprights. They also typically provide little or no rear protection for the upright posts they are supposed to protect.
An example of a plastic guard/protector is the Eye-Catcher Innovations™ Protect-lt™ rack protection system/protector apparatus which is the subject of Australian patent No. 2004290611, and which is disclosed in International Patent Publication No. WO 2005/049453.
It is against this background that the present invention has been developed.

Best Mode(s) for Carrying out the Invention
In the drawings, like features of the various embodiments have been referenced with like reference numbers.
Referring to figures 1 and 2, there is depicted a protector apparatus 20 for protecting a structural member from being damaged by an impact with an object.
Apparatus 20 includes an elongate body 21 which includes a front bumper 22 for absorbing frontal impacts, and a pair of rear side walls 23 which extend from, and which are integrally formed with the front bumper 22.
Front bumper 22 has a hollow profile which has a trapezoidal shape. The trapezoidal shaped profile of the front bumper 22 is optimised so that the front bumper 22 is able to absorb impacts with objects. A rear wall 30 of the front bumper 22 includes a central ridge 31 for engaging with a front wall of the structural member which is protected by the apparatus 20. A front wall 32 of the front bumper 22 is spaced apart from the rear wall 30 and includes a front face/surface 33.
Front bumper 22 also includes a pair of side walls 34 extending between the rear wall 30 and the front wall 32 of the front bumper 22. Each side wall 34 includes an angled or inclined side face/surface 35 for deflecting objects away from the structural member which is protected by the apparatus 20.
Each of the rear side walls 23 includes a front portion 40, an intermediate portion 41 which extends from the front portion 40, and a rear portion 42 which extends from the intermediate portion 41.
Each intermediate portion 41 includes an angled or inclined outer face/surface 43 for deflecting objects away from the structural member which is protected by the apparatus 20 (hereinafer referred to as an angled outer face), a ridge 44 for insertion into a channel in a side wall of the structural member, and an angled or inclined inner face/surface 45 for contacting the structural member side wall so that the rear side walls 23 are able to clamp on to the structural member (hereinafer referred to as an angled inner face).
The rear portions 42 of the rear side walls 23 are able to prevent a rear portion of the structural member which is protected by the apparatus 20 from being impacted and damaged by objects 6 2011221368 10 Feb 2017
In one preferred form, the whole body 21 is formed from the same resiliently flexible material. For example, the whole body 21 may be formed from EPDM (ethylene propylene diene monomer) rubber that has a hardness of 75 -85 Duro. EPDM is a resilient rubber that is chlorine free and that is capable of withstanding temperatures up to 120 Ό and down to -40 C° without its performance being affected.
In an alternative preferred form, at least the front wall 32 and the side walls 34 of the front bumper 22 are formed from a resiliently flexible first material, and the rear side walls 23 are formed from a resiliently flexible second material which is stiffer or harder than the first material. For example, the first material and the second material may be a rubber or plastic material, and the rubber or plastic which the front bumper 22 is formed from may be a softer grade of rubber or plastic compared to the rubber or plastic which the rear side walls 23 are formed from.
If the first and second materials are rubber materials, it is preferred that the first and second materials are both EPDM (ethylene propylene diene monomer) rubber of differing stiffness or hardness. Alternatively, if the first and second materials are plastic materials, it is preferred that the first and second materials are both PVC (polyvinyl chloride) of differing stiffness or hardness.
Forming the front bumper 22 from the more flexible first material rather than the second material provides the front bumper 22 with superior impact absorption and shape retention properties.
On the other hand, forming the rear side walls 23 from the second material rather than the first material increases the clamping effect of the rear side walls 23 on the structural member which is protected by the apparatus 20 so that the apparatus 20 is able to be more securely clamped to the structural member. Although stiffer than the first material, the second material is still flexible enough to be able to absorb an impact between an object and one or both of the rear side walls 23.
The mechanical properties of rubber (e.g. EPDM rubber) are such that, compared to many other materials, it can take or withstand a greater amount of strain before failure. This implies that rubber is able to provide a greater amount of impact energy absorption. Rubber is also very elastic and cannot be permanently deformed unless its elastic limit, which is far higher than many other 7 2011221368 10 Feb 2017 materials, is exceeded. In addition, rubber has good damping properties, and is consequently able to dissipate impact energy better than many other materials.
Irrespective of the material or materials that the body 21 is formed from, it is preferred that the material(s) is/are UV stabilised, flame retardant, and recyclable.
Apparatus 20 is formed using an extruding process which enables the apparatus 20 to be extruded to any required length.
Referring to figures 3 and 4, an assembly 50 includes the protector apparatus 20 secured to a structural member in the form of an upright post 51 for a rack or other structure.
Post 51 includes a front wall 52 which includes a central channel 53, and a plurality of openings 54. Channel 53 functions as a web-stiffener which stiffens/increases the rigidity of the front wall 52. A pair of side walls 55 extends from the front wall 52. Each side wall 55 includes a front portion 56, a channel 57, a plurality of openings 58 which are located at the bottom of the channel 57, and a rear flange 59 which includes an edge 60.
Apparatus 20 is secured to the post 51 by locating the rear side walls 23 of the apparatus 20 adjacent to the sides of the post 51 so that the front wall 52 of the post 51 is substantially located between the rear side walls 23. The apparatus 20 is then pressed or otherwise forced against the post 51 so that the rear side walls 23 spread apart from each other sufficiently to allow the post 51 to enter the space or channel between the side walls 23. Apparatus 20 is pressed or otherwise forced against the post 51 until the ridges 44 of the apparatus 20 are located in the channels 57 and until the ridge 31 locates in the channel 53 and thereby engages with the front wall 52.
The angled inner faces 45 of the rear side walls 23 press against and grip on to the edges 60 of the post side walls 55 so that the post 51 is clamped between the rear side walls 23. The clamping action of the rear side walls 23 also assists in centralising the apparatus 20 relative to the post 51.
The rear portions 42 of the rear side walls 23 extend behind or wrap around the rear flanges 59 of the post 51 so that they are able to prevent an object such as a pallet, for example, from impacting and damaging the rear 8 2011221368 10 Feb 2017 flanges 59 as the pallet is being removed from the rack or other structure which the post 51 may be part of.
The angled outer faces 43 of the rear side walls 23 are able to deflect an object such as a pallet, for example, away from the apparatus 20 and the post 51 as the pallet is being removed/transferred from the rack or other structure which the post 51 may be part of.
Locating the ridge 31 in the channel 53 of the post 51 centralises the apparatus 20 relative to the post 51. This enables the apparatus 20 to be centralised relative to the post 51 even if the width of the front wall 52 of the post 51 differs from that shown.
The angled or inclined side faces 35 of the apparatus 20 are able to assist in guiding or directing an object such as a pallet, for example, which is being inserted into or removed from the rack or other structure which the post 51 is part of. The angled or inclined side faces 35 also allow for easier access in that they allow the pallet to be inserted into or removed from the rack or other structure at an angle.
Figure 5 depicts an assembly 70 which is identical to the assembly 50 except that it includes an upright post 71 rather than the upright post 51 of the assembly 50.
Post 71 is identical to the post 51 except that the front wall 52 of the post 71 does not include the channel 53 of the post 51. Consequently, the ridge 31 of the apparatus 20 is unable to centralise the apparatus 20 relative to the post 71.
Apparatus 20 may also be secured to a large range of other posts whose profiles are different to the posts depicted in the drawings. For example, apparatus 20 may be secured to a post which is configured such that the ridges 44 of the apparatus 20 contact or grip the post. The ridges 44 assist in allowing the apparatus 20 to be fitted to posts having a variety of different profiles.
The rear side walls 23 of the apparatus 20 are able to protect the side walls 55 of the post 51 while minimising ‘clear entry’ obstruction to an object such as a pallet, for example, which is being inserted or removed from the rack or other structure which the post 51 may form part of. The reason for this is that the rear side walls 23 do not increase the frontal width of the body 21 because they do not project out beyond the frontal width of the front bumper 22.
Apparatus 20 can easily be modified to suit applications where the post 9 2011221368 10 Feb 2017 which the apparatus 20 is secured to is part of a structure such as a rack which also includes a bottom beam or other component which presents an obstruction to the apparatus 20. To avoid fouling between the apparatus 20 and the bottom beam or other component, the apparatus 20 can be modified to negotiate/by-pass such an obstruction by cutting one or more portions from one or both rear side walls 23 so as to form one or more cut outs which are able to receive the obstruction.
Referring to figures 6 and 7, there is depicted a protector apparatus 80 for protecting a structural member such as the upright post 51 or 71 from being damaged by an impact with an object.
Apparatus 80 is identical to the apparatus 20 except that the front portion 40 of each rear side wall 23 of the apparatus 80 includes a longitudinally-extending opening 81 and the front portion 40 bows outwardly slightly so as to increase the impact-absorbing/cushioning that is able to be provided by the rear side walls 23 against impacts with objects such as, for example, pallets.
An advantage of the apparatus 50, 80 over prior-art metal guards/protector apparatus is that they are more impact-absorbing which means less transfer of impact load onto the structural member, such as an upright post, which is being protected or the floor which supports the structural member.
In addition, the apparatus 50, 80 are able to provide better rear and side protection compared to prior-art metal guards/protector apparatus.
The apparatus 50, 80 are also more compact compared to prior-art plastic guards/protector apparatus. This allows for greater clearances between unit loads and rack uprights.
Furthermore, the wraparound design of the apparatus 50, 80 means that they are able to provide better rear protection for a structural member compared to prior-art plastic guards/protector apparatus.
