folding tables: correlation height v width
Posted: Sat Feb 18, 2012 1:24 pm
one occasionally sees zither tables with folding (collapsible) legs, with the legs not folding "flat" to the surface of the top. the end result is a table cumbersome and difficult to transport. on these tables, the leg assembly on one side of the table is frequently more narrow than on the other, so that the left hand and right hand leg assemblies collapse (or fold) between one another.
in this discussion the term "length" will be used to describe the dimension of the table from left to right, not (depth) from the player to the note stand. height will be the dimension from the floor to the table top surface.
it seems there might be a correlation between the length of the table and the table height, if the legs are to fold flat.
the length of the leg assembly includes the actual length of the legs, plus length added by any cross bracing, if it extends above the top of the legs.
the entire leg assembly must include the width of the side board and twice the width of the leg/cross-bracing sub-assembly. the top length must then reflect the sum of these ON EACH SIDE. if one selects wood stock of equal thickness for the side, the leg/cross-bracing assembly, and then does the same on both sides of the table, the minimum table length for the legs to fold flat under the table and between the sides will be the length of the leg assembly plus six times the thickness of the stock used. one should of course add a cm or so for assurance. for example, if it is desired to have a table 60 cm tall from the floor to the top, if the legs are 57.5 cm, and the wood stock used for the sides and the table leg/cross brace assembly is 2.5 cm, then the absolute minimum length of the table will be 57.5 + 6 x 2.5 = 72.5 cm. adding a cm or so for "play" would make the length 73+ cm
if this is done, the table should fold flat. this should apply to both the solid top as well as the "open face" style tables.
any comments??
