Typewriter Desk-Case

Browsing an old Popular Science magazine, spotted this typewriter desk-case.

The typewriter case that folds open to form a proper table was patented, published as US patent 1,661,015 filed in 1926 and published in February 1928.

The case folded open as a table.

And closed for keeping the typewriter in it (and all the legs as well...).

Somehow it didn't catch on. Wonder if the design actually made it beyond one prototype. Compared to the later travel tripod cases from e.g. Underwood, the design perhaps has drawbacks:
- Even though it's a complete desk, the typewriter needs to be taken out of the case completely and then placed loose on the table-top (the outside of the case).
-The case cannot be used in the normal portable manner, cannot just open the lid to have the machine available for use.
- The complete desk and folding wooden legs likely are somewhat heavier and bulkier than a metal tripod in a regular case.
- The narrow wooden 4-legged table needs a decent surface to stand on, a three-legged stand is likely more forgiving and stable for typing use. An adjustable leg's a hassle (and cost).

Nevertheless; an ingenious case it is.

This type of folding case seems to have been 'in the air', looking at this folding lunch table/box from the same year...
