Abstract

Point-of-Sale printers are frequently positioned such that the printer slopes forward as much as 45 degrees. As a result, the cover will not stay in its open position and could "slam" closed, accidentally injuring someone or damaging the printer. This disclosure solves the problem by providing a friction force that will hold the cover at any angle.

Cover Positioning and Up-Stop Device

      Point-of-Sale printers are frequently positioned such that the
printer slopes forward as much as 45 degrees.  As a result, the cover
will not stay in its open position and could "slam" closed,
accidentally injuring someone or damaging the printer.  This
disclosure solves the problem by providing a friction force that will
hold the cover at any angle.

      The solution, shown in Fig. 1, is a combination cover stop and
friction device.  It consists of a strap that is flexed to create a
normal load which causes a friction force that resists motion of the
cover.  This friction force can be constant for any position of the
cover.  When the strap is fully extended, the bottom detail hooks on
the fixed cover to limit the opening angle of that cover.

      Fig. 2 shows the application of the friction strap.  The
friction force is large enough to support the weight of the cover at
any angle which prevents the cover from "slamming" closed.  The
friction strap provides both force on the cover and an up stop for
the cover.  Changing the width or thickness of the friction strap can
provide varying forces as a function of cover angle.  The cover can
be held up at  any position between completely open and completely
closed.
