Abstract

This hinge integrates several features: it constrains the amount of cover swing, allows cover removal without the use of tools, covers cannot be removed until swung open past a pre-defined angle to prevent inadvertent cover removal, additional/stray parts are not needed to achieve the above features, and allows for adjustability between the cover and its mating surface.

Adjustable, Removable Cover Hinge

      This hinge integrates several features:  it constrains the
amount of cover swing, allows cover removal without the use of tools,
covers cannot be removed until swung open past a pre-defined angle to
prevent inadvertent cover removal, additional/stray parts are not
needed to achieve the above features, and allows for adjustability
between the cover and its mating surface.

      As shown in the Figure, the hinge (1) mounts onto the frame
(12) using two bolts.  These bolts fit through two holes (4) in the
frame hinge and screw into the frame (12).  The hole diameters are
larger than the bolts, therefore providing the necessary cover
adjustability in the directions shown on the diagram (10).

      The cover hinge (2) is welded onto the cover (9) and slides
over the frame hinge pin (3) upon assembly.  The frame hinge pin (3)
is rather short, which allows the side covers to be merely lifted (in
the vertical direction without tools) without interfering with the
top cover (11).

      In order to avoid inadvertent removal, the cover hinge (2) has
a step-like feature (6) which, in conjunction with the frame hinge
feature (5), only allows cover removal at angles of 90 degrees or
more (Can be adjusted to any desired angle).  At angles less than 90
degrees, the raised step (6) is vertically constrained by the frame
hinge feature (5), thus preventing inadvertent cover removal.

      Finally, the amount of cover swing is...
