At that age my son had his own cupboard in the kitchen which I just filled with plastic containers, old bits of kitchen equipment etc. He loved opening it and dragging everything out. Messy, but it kept him entertained for 20 to 30 minute stretches which is probably all you can expect at 14 months.

Another thing for desperate moments - fill up an old handbag with bits and pieces and pull it out occasionally (not too often or it loses its appeal).
