  • FIG. 1 is a plan view of a cover and carrying case for a portable typewriter according to the invention, where som parts have been removed for purpose of clarity;
  • FIG. 2 is a longitudinal partial sectional view of the cover and carrying case of FIG. I;
  • FIG. 3 is a partial sectional view taken according to line III-III of FIG. 1.
  • the carrying case of the portable typewriter is integrated with the machine itself, since some parts of the case form also the machine cover, whereby it will be hereinafter named cover and carrying case.
  • the cover and carrying case is formed of a conventional plastic material adapted to resist to accidental shocks, for example the material marketed under the name Delrin.
  • the cover and carrying case comprise a base 3, which is secured by means of four screws 4 to four projections 5 (FIG. 2) of the machine frame.
  • the screws 4 are also secured to 4 feet 6 of the typewriter, made with an elastic material.
  • Some mechanisms of the typewriter, including the paper carriage, the type action and the keyboards are shown by broken lines in FIGS. 1 and 2. Therefore the base 3 forms both the bottom of the machine cover and the bottom of the carrying case.
  • the base 3 is integral with a rear wall 7 (FIG. 2) which is provided with two projections 8 for placing the case when closed on the floor.
  • the base 3 is also provided on the front with an upreaching border 9 and on both lateral rides with two upreaching borders l0.

  • the shell 38 is also provided with a pair of lateral tongues 46 directed downwards, which are located outside the conventional flanks of the machine frame, not shown in the drawings, to assist the operator in roughly centering the shell 38 during the insertion of the base 3.
  • This latter is provided on each side with three projections 47 integral therewith and having the upper edge 48 (FIG. 3) inclined outwards and adapt to enable the operator to exactly center the shell 38 at the end of the movement for inserting it into the base 3.
  • the aperture 39 is defined at the opposite sides by a pair of flanges 49 directed downwards.
  • Each flange 49'-- is provided with a projection 51 having a tooth 52 protruding toward the middle of the machine.
  • the lower surface of the tooth 52 is inclined to temporarily remove the lug 36 of the corresponding lever 29 when the shell 38 isinserted into the base 3.
  • the cover and carrying case comprise also an outer shell generically indicated by the numeral 53, which is a part of the case itself.
  • the front edge of the shell 53 is adapted to lean on the abutment 17 (FIG. 2) of the border 9, whereas the two side edges of the shell are adapted to lean on the abutment I7 of the border 10 (FIG. 3) and the arcuate portions 11.
  • the shell 53 leans rearwards on the upper edge of the wall 7 (FIG. 2) and is provided with a pair of flanges 54 (FIG. 1) having a shickle-shaped section.
  • Each flange 54 is adapted to engage the corresponding vane 13 and rockably cooperate with the border 14.
  • Each flange 54 is reinforced with a set of plates 56 integral with the shell 53 and with .the flange 54.
  • a rigid handle 57 Integral with the forward part of the shroud 53 is a rigid handle 57, which is provided at the two ends of the front side thereof with two square apertures 58.
  • Each aperture 58 houses a correspondingly depressible key 59 (FIG. 2) secured to a key stem 60, which is slidable in a rectilinear guide hole 61 of the handle 57.
  • the rear end of the stem 60 is provided with a notch 62 engaging a pin 63 of an arm 64 secured to a corresponding transverse bar 65, rotatable on a pair of projection 66 of the shell 53.
  • the arm 64 is provided with a projection 67 engaged by one end of a compression spring 68, which is housed in a hole of a projection 69 integral with the shell 53.
  • the arm 64 is provided with a lug 75 adapted to be arrested against a front wall 76 of the shell 53.
  • the bar 65 is directed outwards and is secured at the outer end to a corresponding latch 70, which is adapted to enter the aperture 39 of the inner shell adjacent to the corresponding flange 49.

  • the lower edge 72 of the tooth 71 is suitably inclined as shown in FIG. 2.
  • the outer shell 53 is internally covered by a thin sheet of plastic 73, which is suitably shaped to cover the projection 67 of the arm 64.
  • the sheet 73 is secured to the shell 53 in a known manner and is provided with a pair of notches 74 crossed by the latch 70.
  • the carrying case can be open by intentionally depressing the two keys 59 simultaneously with the two hands. It is thus avoided that the case be open when just one key 59 is accidentally depressed.
  • Each key 59, through the stem 60 rocks then the corresponding arm 64 (FIG. 2) counterclockwise together with the bar 65 and the latch 70. This latter disengages its tooth 71 from the hole 27 of the plate 23, whereby the shell 53 can be rocked with the flanges 54 around the border 14, till the flanges 54 can be disengaged from the apertures 13.
  • the operator acts on the lugs 37 (FIG. 3) of the levers 29 with two fingers of the two hands through the aperture 39 of the shell 38, in such a manner as to push the lugs 37 outwards against the urge of the springs 34.
  • the lug 36 of each lever 29 releases then the tooth 52 of the corresponding flange 49'(FIG. 2), whereby the inner shell 38 can be rocked around the projections 44 and then removed from the base 3.
