Many years ago I built several flat show cases. They were wood
edged boxes about 4" deep with a wood framed hinged glass lid. I
installed triangular shaped Plexiglas side panels that were hinged
to the base. The sides, when lifted up held the case open and
provided protection from someone reaching into the case. I designed
a spring catch that locked the lid closed whenever it was lowered.
To lock the case all I had to do was raise the lid about 1/4" and
the side would fold down. When the lid was dropped against the
lower box the catch would lock the case. I had the cases bolted to
the table. I was slightly paranoid. I felt if someone ran with a
piece I could drop the lids and chase after them without having the
rest of my jewelry lifted. I only do two shows a year now. I do not
put out anything out on the table that is easily lifted. However
the chance of a sale increases if you can get the customer to hold
the piece they are interested in. I knew an artist that pinned all
his jewelry to the table cover. This prevented anyone from lifting
a piece when he was occupied with another sale.
I have known artists that will deal with only one customer at time
and with only one piece at a time. All cases with hinged lids
should have side panels. Plexiglas type material can be purchased at
home depot and cut to fit into the case between the hinged lid and
the bottom of the box. Lee
