Definitions

  • a housing for electrically operated typewriters and similar machines, such as Telex machines, is com- BO] Forelgn Apphcatmn Pnonty Data posed of a plurality of individual parts, i.e., front, Aug. 30, 1972 Germany 2242569 back, Side and top wall members assembled together and secured to a top frame which has a separable cou- 5 197/186 pling device by which the assembly is secured to a J pp ti g b h i g means f eiving and secur- [58] held of searchm" 197/186 186 B; 312/208 ing the coupling device and complete a cabinet for the 312/263 machine enclosed within the housing.
  • cabinet housings for machines of the character indicated consist basically of a one part housing shell which encloses the machine.
  • Such housing shell is secured to the base plate which supports the machine, such, for example, as by bolting or screwing the same in position to provide a stable assembly.
  • a one piece shell design of the housing is quite expensive, in particular because the forms and dies which are required for production are very complicated.
  • a housing in particular for electronic table calculators, might be constructed of cabinet components which are held to the base plate of the machine and constructed in such a way that the base plate has knock-out spindles by which the individually removable housing parts are joined together in a grouped relation around the base plate to complete the housing unit, the individual housing parts being attached in such a way that they can be dismantled.
  • a housing thus constructed does have advantages from a production standpoint, those advantages are adversely affected due to lack of stability of the housing and an impairment of the desired requirements for such a housing such as to enable servicing of the housed machine. If any of the individual components of the machine are to be checked or exchanged, it is required by the prior arrangement to disassemble the cabinet housing parts individually and then to replace the individual parts after completion of overhauling of the machine.
  • Another object of the invention is to provide a new and improved housing for electrically operated typewriters and similar machines and which meets the problem of ready access to the enclosed machine and components thereof in a simple, easy and manner.
  • a further object of the invention is to provide a new and improved housing of the character indicated in which individual elements of the housing are assembled with one another in a manner to facilitate handling as a unit for attachment to and removal from a machinesupporting base.
  • Still another object of the invention is to provide new and improved means for connecting the front, rear. and side walls of a separable housing with a base plate.
  • a further object of the invention is to'provide a new and improved means for improving the form-stability of a housing composed .of an assembly of multiple parts;

  • Other openings are provided in the wall 2 as necessary for its specific adaptation to the enclosed machine.
  • the housing has two side wall parts 6, a back wall 7 and a top wall 8 in the form of a top access opening closure cover.
  • the cabinet may be provided with a hingedly mounted cover C for protectively closing the front of the housing in the keyboard area, that is to li across the front of the front wall 2 when the machine is not in use.
  • the cover C is shown only in FIG. 1 and is omitted from the remaining figures because it is not an essential element of the inventive features of the present application.
  • the base plat 1 may be formed as a lightweight metal casting or from a rigid high impact strength plastic material
  • the wall members 2, 6, 7 at least, and also the top wall closure 8 if desired may be made from an easily shaped relatively soft, but form sustaining plastic material having low resonance characteristics contributing to vibration and sound damping.
  • the front wall member, a side wall member 6, the rear wall member 7, and the top closure wall member 8 are all made as individual, separate components, but constructed and arranged so that they can be mounted in assembly with each other on a top frame comprising an angular generally ringshaped member 9.
  • connecting and reenforcing bars 10 are provided for stabilizing the connection of the side wall member 6 with the front wall member 2 and the rear wall member 7 along the lower portion of the housing shell assembly.
  • Pivotal attachment of the top wall cover member 8 enabling opening and closing thereof is effected by means of a pair of butt hinges 11 having one hinge plate secured to the rear portion of the cover 8 and the remaining plate secured as by means of screws lla to upper edge flange structure 7a of the back wall member 7 and which flange structure engages supportingly on the frame member 9 to which the flange structure is fixedly secured by means of the screws lla.
  • the cover 8 In its closed position, the cover 8 is held by spring latches 8a engaging with suitable keepers 8b (FIG. 3), from which the latches are adapted to be released by pressing them inwardly against spring bias.
  • the cover 8 in its raised, open position, the cover 8 is adapted to be held by means of a pair of depending curved brace bar members 12, one at each side, pivoted at upper ends to the rear portion of the cover member 8 and depending therefrom through respective slots 13 in the frame member 9.
  • the brace bars 12 Adjacent their lower ends, the brace bars 12 have latching notches 320 which are engagable with the frame member 9 in the raised position of the cover.
  • the latch members 8a are actuated in opposition to their spring bias to operate respective trip rods 12b suitably coupled with the upper end portions of the brace members I2.
  • the frame member 9 is preferably constructed from suitable metal and may be produced by die casting. It is constructed and arranged to receive the upper end portions of the front wall member 2, the side wall members 6, and the rear wall member 7 in efficient assembly therewith. Suitable upper edge inturned flange portions on the front wall member 2 and the side wall member 6 engage upon respective front and side bar portions of the frame member 9, a depending attachment flange 90 along the front of the frame member being secured to the upper portion of the front wall member 2 as by means of screws to A (FIG. 3).
  • the frame member 9 is provided with depending flange portlon's 9b to which the upper portions of the side housing members 6 are secured as by means of screws 6a (FIG. 1).
