Abstract

A high torque transmitting coupling is disclosed suitable for pivotable disengagement between a driving shaft and a driven shaft, such as for providing a coupling between a drive motor in a copier base unit and driven elements, such as belts, etc., in an accessory unit which pivotally connects with the copier base unit. An automatically disengageable and non-axially meshing coupling which can be automatically engaged by the pivoting of the accessory unit is provided.

A high torque transmitting coupling is disclosed suitable for
pivotable disengagement between a driving shaft and a driven
shaft, such as for providing a coupling between a drive motor
in a copier base unit and driven elements, such as belts,
etc., in an accessory unit which pivotally connects with the
copier base unit. An automatically disengageable and non~
axially meshing coupling which can be automatically engaged by
the pivoting of the accessory unit is provided.

Frictional type couplings or clutches are known in such appli~
cations, but are not suitable for reliably providing high
torque transmission. Couplings with fixed meshing teeth or
lugs are not suitable where there is a possibility that a non~
meshing engagement of fixed teeth could cause damage to the
coupling, or prevent the full pivotable movement of the acces~
sory unit into its desired position. A coupling where the
opposing meshing teeth or lugs have sharp edges, i.e., are
wedge shaped, so as to be self~aligning as the coupling

closes, can cause one member of the coupling to be rotated
relative to the other as the coupling closes, which movement
is undesirable for certain applications.

The present structure shown in Figures 1 - 3 overcomes these
problems by providing multiple (e.g., three or more) lugs 10
on one coupling member 11, which lugs 10 are individually
pivotable and spring loaded and contoured (relieved) to snap
into mating recesses 12 on the other coupling member 13 as
shown in Figure 2. The coupling member 13 is individually
shown in a plan view in Figure 3 to better illustrate its
coupling recesses 12. The lugs 10 in the...
