  • the latching handle includes a V-shaped lever handle construction which is pivoted at one leg to permit it to be swung upwardly to free the latching cap from the proturbance formed on the opposite element.
  • the construction includes interlocking means on an opposite side of the housing which is oriented and which permits pivotal movement of the parts together and then the interlocking thereof by means of the latching cap arrangement.
  • both the stationary formation and the latching lever form a handle which permits the In devices of this nature it is usually necessary easy transportation of the device by the user throughout the household.
  • the construction advantageously includes a biasing spring arrangement formed in a U-shaped latching lever handle which tends to bias the handle in a closed position in which a cap portion covers a protuberance on the adjacent housing section.
  • a further object of the invention is to provide an improved latching and handle device for interconnecting housing parts.
  • a further object of the invention is to provide a handle latch construction which includes a housing element having a permanent handle member and a lever handle portion pivotally mounted at one end on said housing, includig a cap element and pivotally connected to a spring element of the hand lever adapted to extend outwardly from Patented Nov. 3, 1964 the lever portion, the hand lever being positionable to latch the cap member over a projecting portion of another housing element.
  • a further object of the invention is to provide a housing and handle latching device for a household appliance which is simple in design, rugged in construction, and economical to manufacture.
  • FIG. 1 is a partial side elevation and partial longitudinal section of a vacuum cleaner having an interlocking handle construction in accordance with the invention.
  • FIG. 2 is a top plan view of the device indicated in FIG. 1.
  • the invention embodied therein includes a vacuum cleaner generally designated 39 which includes a housing portion 1 in which is located an electric motor for driving thedevice and a housing portion 5 which carries the dust bag for collecting the dust which is accumulated during vacuum cleaning. r
  • the housing portion 1 is fitted together with the housing portion 5 by means of a novel interlocking arrangement and handle construction.
  • the handle construction comprises an outside U-shaped handle element or handle lever member 2 which is pivotally mounted at its forward end on bolt element 3 which is journaled in a central bearing carried at the forward top end of the housing 1 adjacent the line of separation 4 between the housing parts 1 and 5.
  • a substantially U-shaped spring member 6 is carried by means of spanning brackets 32 held to the lever 2 by means of holding pins '7 and fitted against a recess defined by an inturned wall portion 33 of the handle lever 2.
  • Spring 6 includes leg portions which extend into bearing elements of arm projections 34 and 35 of a cap member generally designated 8.
  • the cap member 8 is generally trapezoidal in shape and is of a length permitting the forward end thereof to be engaged around an upstanding abutment or latching part 13 formed on the housing 5 at a location extending inwardly from the line of separation 4.
  • the latching part or abutment 13 is of substantially the same trapezoidal shape as the cover 8 but of a lesser dimension to permit the cover to be easily positioned thereover, when the handle is in an upward position, as indicated in dotted lines in FIG. 1.
  • the spring element 10 includes a curved portion which fits into a curved recess 11 formed at this end of the handle lever 2.
  • the arms 34, 35 are advantageously made as an integral portion of the cap 8 and they fit through slots provided at each side of the handle lever 2.
  • the handle lever 2 may be easily moved to the dotted line position by pulling upwardly to cause the spring 10 to be flexed to release the handle.
  • a feature of the construction is that the handle lever 2 overlies a permanent U-shaped handle formation 12 which is defined at the upper end of the housing 1. In the operative or carrying position the handle lever 2 directly overlies the fixed handle portion 12 and the combined arrangement permits easy handling of the device by directing the fingers through the open space 121: formed between the handle 12 and the housing 1.
  • a further feature of the invention is the formation of the opposite side of the housing 1 and the housing to permit interlocking thereof.
  • the socket and plug arrangement advantageously includes a hook element 14 connected at the end of the housing 5 which engages in a recess 15 formed by projecting element 17 at the end of the housing 1.
  • the hook 14 is advantageously formed by an angle sheet iron 16 which is fixed to the housing 5 and bent in the configuration indicated.
  • the recess 15 is advantageously formed by a single strip of sheet metal17 which is advantageously bent in a configuration to define a protuberance 17' and a downwardly extending wall which forms the recess 15.
  • the housewife need only place the hook portion 14 of the housing 5 behind the recess 15 of thehousing 1 to interengage the housing elements. This is more or less done automatically when the housewife puts the connecting housing 5 in oblique downwardly inclined position and then turns it upward, as described by the arrow indicated in FIG. 1. Thereafter the hand lever 2 is rocked from the dotted line position to permit the cap element or hook element 8 to be hooked over the protuberance or latching element 13. Thereafter the hand lever 2 is pivoted about the bolts 3 and snaps downwardly against the spring which holds it in place and tightly engages the cap or hook 8 over the locking element 13.
