1 About Easy-steer ergonomic castors Castors should be easy to steer without sacrificing a brake option. When no such castors existed, we invented them! Our Trinity and NDL castors have been purpose designed for easy steering. Intelligently simple, smart product design: Font: Hand of Sean Fallshaw products are deceptively simple and elegant. We design for form and function: with contemporary styling and without unnecessary components or material. Our products are not constrained by traditional approaches. We enjoy doing things differently: we think anew about material selection and manufacturing technology and we radically reinterpret castor design. Trinity > Castors NDL -inin-1 fixed brake position The problem with traditional directional locking castors is that they re not compatible with total brakes - so you either have to choose to be easy to steer or lockable. With Trinity castors you don t have to choose, you can have both! < castors Natural Directional Lock Tucked away underneath the castor is the business end of automatic, intuitive steering When the wheel is travelling forward, the rocker moves the tooth up into the slot. When the wheel is travelling backward, the rocker moves the tooth down out of the slot. up: directional lock neutral: swivel down: total brake 0 From a user-perspective none of this matters! The Natural Directional Lock castor is intuitive to use - customers feel how to use it without being taught. They naturally figure it out within about 0 seconds. And from then on the trolley is magically easy to steer and push...

3 Designing trolleys 2 Castor configurations & wheel size Large wheels are easier to push. The most common mistake when fitting castors is to fit wheel diameters too small for the real needs of the trolley and its user. The surveys, both in Australia and overseas, show again and again that small castors which get caught in uneven floors, ridges, gaps and holes, cause many injuries. Large diameter wheels, as against small wheels, will often add less than 10% to the cost of the trolley, and yet make that trolley 00% easier to use. The guideline is for a minimum diameter of: 12mm ( ) for non-patient trolleys 17mm (7 ) for patient trolleys used indoors 200mm (8 ) for trolleys used out doors or for loads over 200kg (8lb) Smaller castors can still be used in restricted circumstances, for instance, use on lightweight equipment. In general, castors of: mm ( ) size are recommended up to 120kg (2lb) trolley loads, but only on smooth floors and for short distances. They can be used on ward furniture, but not on catering or hospitality equipment. 7mm ( ) are even more restricted, being recommended only up to kg (220lb) trolley loads and again only on smooth floors without obstructions for short distances. 0mm (2 ) are recommended only up to 80kg (17lb) trolley loads and for very short distances. If used on carpets a maximum load of 0kg (110lb) is appropriate. The research is absolutely clear: large diameter wheels reduce forces for all trolley movements. Larger wheels: are easier to roll along the length of corridors, over ridges, e.g. at the edge of carpets, into lifts reduce vibration to patients and equipment and minimise shock transferring to the user s arms from impacts are more robust/resistant to damage, remain functioning efficiently for longer than smaller wheels. Consider also the other castor features that will effect push effort and ride comfort: tyre material tyre width & profile bearing type (in the wheel and the castor head race) use of threadguards type and number of castor brakes (including directional lock) heavy trolley: fixed at front (eg. hospital beds) light trolleys: fixed at rear (eg. shopping trolleys) Direction of travel Manoeuvrability Stability Steering Traditional configurations swivel 2 swivel 2 fixed or DL 2 swivel 2 fixed swivel 2 fixed World best practice configurations 2 NDL 2 swivel NDL - Natural Directional Lock (see page 8 for information) 1 NDL kit swivel (1 x spring-loaded central mount) NDL - Natural Directional Lock (see page 8 for information) Trinity CB or TB Trinity Castors (see page for information) Maximum.

4 Trolley design principles - human factors No objects should block the clear line of sight above 100mm ( 7 ) Any shelves in the area less than 00mm (2 ) should be infrequently used and for light obejcts (less than 10kg (22lb)). Maximum shelf depth in this area should be 0mm (1 ). Any shelves in the area between 00 & 800mm (2 & 2 8 ) should be infrequently used. Maximum shelf depth in this area should be 0mm (1 ) The area between 800 & 1mm (2 8 & 8 ) is the best area for people to frequently access heavier objects (more than 10kg (22lb)) - bending is minimised, and the lifting position is optimal. Maximum shelf depth in this area should be 800mm (2 8 ) Any shelves in the area between 1 ( 8 ) & 100 ( 7 ) should be infrequently used and for light objects (less than 10kg (22lb)). Maximum shelf depth in this area should be 00mm (1 ) Trolley design fundamentals A trolley should be: Not too wide: Hand pushed trolleys should be at least 80mm (/1 ) narrower than the narrowest doorway. Towed trolleys should be 00mm (17/8 ) narrower than the narrowest isle or doorway, and more if towed in a train. Not too long: Trolley length should be between 1. to 2 times the width, otherwise it will not track smoothly around corners. If it must be long, you may need to experiment to find the best castor arrangement to suit your particular needs. Not too high: A maximum height of 100mm ( 7 ) is recommended (including the goods being carried) to enable a clear line of sight. Not too light: As a rough guide, the weight of the trolley is usually 1% to 20% of the load it is to carry. For the castor to function properly, the frame of the trolley must be strong enough to hold the castor head truly vertical so it can swivel freely (that is, the mounting plate must remain horizontal, or the stem must remain vertical), and the frame must not bend under the impacts that inevitably occur. The most common cause of castors not tracking properly is that the mounting has twisted off square. Not too heavy: It is often safer, and more efficient, to divide the heavy load over a number of trolleys rather than concentrating it into one. Trolleys which are too heavy to move commonly remain unused, or people suffer back injuries. Handle height & position Optimal handle height for average females is 910mm ( ) Optimal handle height for average males is 990mm ( ) A good compromise handle height for mixed users is 90mm ( 11/2 ). If a trolley is to be pulled (and most are at some time), the handle should be located far enough out from the trolley to ensure feet do not hit the trolley (approx. 00mm (1 )). This can be closer if the trolley has no shelves or tubes below 0mm (1 / ) Trolley push effort Occupational Health & Safety experts recommend the following safety suggestions: Push efforts for trolleys, beds and mobile equipment Initial force: 17-21N (17-21kg) (7. -.2lb) Sustained force for infrequent, short distances 0-120N ( - 12kg) (1.2-2.lb) Spring scales are a simple, accurate way to measure push effort. They are very cheap to buy and are available from most hardware stores. Simply clip the hook of the scale and pull until the trolley begins to move. If it takes less than 17kg (7.lb) to get the trolley moving and less than kg (1.2lb) to keep it moving, then the trolley design and work load are bestpractice. Most trolleys actually measured in surveys of hospitals were only within these recommendations if lightly loaded and used on smooth, hard floors. Often, as the trolleys were more heavily loaded up to their design capacity, they exceeded these recommendations, often doubling, and sometimes needing six times the recommended force. For example, simply moving from a hard, smooth floor to a carpeted area could more than double the force required.

Sometimes customers want to travel sideways (particularly when moving aside for passing customers in narrow aisles).

9 new product Sometimes customers want to travel in a straight line (without having to crab-steer or battle with the trolley). swivel castors make this difficult (particularly when the trolley is full and on a slope in the car park). Sometimes customers want to travel sideways (particularly when moving aside for passing customers in narrow aisles). 2 fixed rear castors (which aide steering and are widely used in the USA and NZ) make this impossible. Natural Directional Lock Natural Directional Lock (NDL) castors make steering easy Fallshaw Natural Directional Lock (NDL) castors are designed specifically to resolve hard-to-steer trolleys and eradicate confusing directional lock systems. The NDL caster intuitively locks the castor from swivelling when travelling in a forward motion. A simple motion (reversing by a few millimetres something that people do intuitively) then releases the swivel lock allowing the trolley to be fully manoeuvered in any direction. There is no other similar product on the market. The castor design is patented (Patent number: AU200277).
