    Adaptorforan axleField ofthe InventionThe present invention relates to an adaptor foran axle, wherethe axle defines the cen-tre of rotation for transmission of the rotational movement to at least one access or5 attachment point, wlñcli 1s eccentric with the axis of rotation, where the adaptor isdisc-shape with an outer perimeter and an inner perimeter, where the inner perimeterhasa shape which fits the axle. Furthermore, the adaptor includes securing means forsecuring the adaptor tothe axle.10 Backg•round ofthe InventionIn lighting arrangements or fixtures, you often need to fasten an adaptor to an axlemechanically. A common wayof doing this is by forcinga set screw iriounted on theadaptor into the axle. However, this causesa numbel of difficulties. The set screwamong others creates bunsinthe axle. ThesC burrs will make it difficult to removethe15 adaptor or even rotate it some degrees if it is neededin connection with adjustment.A way to avoid the burrs is to createa squeCze adaptor to overcome the before-mentioned drawbacks. This could be an adaptor made from alloy such as die castezinc. Instead of forcinga set screw into the axle,a normal screw is used to applya20 clamping or squeezing force around the axle and in this way avoid any burrs on theaxle. This kind of adaptor works except fortwo things. First, it v•as ›•ery sensitive tothe amountof torque needed to fasten the screw. Ifthe amountof torque is too little, itwould not clamp, and ifthe amount of torque is too high, it v•ould causea permanentdeformation or cracking of the adaptor. Second, it has reduced clamping force over25 time. The actual reasons are partly due to the material and partly due to the design. Ifexposed to high temperatures and tension forces, zinc will creep over time. The designwitha slot on each side of the axle makes it even worse. When tightening the screw,the slot would become narrower on the screw side, but, unfortunately, it would alsobecome wider on the opposite side. This causes another drawback asthe rivet holes30 ”moves“ angularlyup towards the screw. These problems are further enhanced as mostCONFIRMATION COPY
