Definitions

  • My invention relates to vacuum cleaners of the type which employ a removable dust collecting member, and it is an object of the invention to provide an improvement to prevent seating of a cover at an access opening of such a cleaner unless a dust collecting member is positioned therein.
  • Fig. 1 is a side view, partly in section, of a vacuum cleaner embodying my invention
  • Fig. 2 is an enlarged fragmentary sectional view of part of the construction shown in Fig. 1;
  • Fig. 3 is a sectional view similar to Fig, 2 with the details of the dust collecting member omitted;
  • Fig. 4 is a sectional view like that of Fig. 2 illustrating another embodiment of the invention.
  • the vacuum cleaner which I have shown embodying my invention includes a casing having a space 11 at one end thereof which receives a dust collecting member 12.
  • the dust collecting member 12 comprises a filter bag 14 which may be formed of fabric or other suitable material permeable to air, and a part 15 of annular form which is fixed to the bag at the open end thereof.
  • the part 15, which is essentially ring-shaped and serves as a reenforcement, is formed with an outwardly extending flange 16 to which is fixed a gasket 17 which may be formed of resilient ma terial like rubber, for example.
  • a front cover 18 is provided for the casing 10 to close the access opening 19 of space 11 and also effectively hold the gasket 17 between the end of the casing and the cover, in a manner which will be described presently.
  • the cover 18 and also a rear hood 20 may be fixed to the casing with any suitable fastening provisions.
  • the casing 10 is provided with a handle 21 and also a pair of runners 22 to facilitate movement thereof on a supporting surface.
  • the cover 18 is formed with a central opening 23 to receive an end of a suction hose (not 2,773,557 Patented Dec. 11, 1956 shown) adapted to be removably secured to the opening in the cover in any suitable manner.
  • Suitable cleaning appliances are connected to the outer free end of the suction hose through which air is drawn into the interior of the casing 10 by a motor fan unit (not shown) which may be positioned adjacent the filter bag 14.
  • I provide the cover 18 which is smaller than the access opening 19 into the space 11, so that the vacuum cleaner cannot be operated with the cover in its closed position until the dust collecting member 12 is properly positioned in the interior of the casing 10.
  • the casing 10 i provided with an end ring 24 having an inwardly extending flange 25 which defines the access opening 19 into the space 11.
  • the diameter of the cover 18 is smaller than that of the access opening 19 so that, when the dust collecting member 12 is removed from the space 11, the cover 18 can be moved through the access opening 19 into the space 11 of the casing 10 in the manner shown in Fig. 3.
  • the gasket 17 acts against the flange 25 which constitutes a shoulder or abutment at the open end of the casing 10 and serves to position the dust collecting member.
  • the ring-shaped part 15, including the gasket 17 carried by the flange part 16 thereof forms a seat for the cover 18, thereby rendering the latter eflective to close the access opening 19 of the casing, as best shown in Fig. 2.
  • the cover 18 With the cover 18 properly seated against the ring-shaped part 15 and also bearing resiliently against the gasket 17 carried thereby, the cover may be removably secured to the casing 10 with any suitable fastening provisions.
  • the cover 18 may be removably secured to the casing by fastening means like that disclosed in Lundvall Patent No, 1,944,291.
  • Fig. 4 diflers from the embodiment just described in that the part 15a of annular form, to which the filter bag 14a is secured, is provided with an outer rim portion 15b which is held between gaskets 17a and 17b held on the cover 18a and open end of the casing 10a, respectively.
  • the cover 18a and end ring 24a are formed to provide ring-shaped grooves which receive the gaskets 17a and 17b, respec tively, which are desirably formed of a resilient material like rubber, for example.
  • the inner diameter of the gasket 17b is greater than the outer diameter of the gasket 17a, and the outer rim 15b of the ring-shaped part 15a, which is clamped between the gaskets 17a and 1717 when the cover 18a is positioned to close the access opening 19a, slopes inwardly from the gasket on the casing 10a to the gasket on the cover 18a.
  • the size and shape of the front end cover are so related to the size and shape of the access opening that, when the dust collecting member is removed from the space in which it is ordinarily positioned during normal operation of the vacuum cleaner. the cover cannot be positioned on the casing to close the access opening.
  • the cover it is necessary to insert the dust collecting member into position in the interior of the casing at the access opening before the cover can be mounted on the casing to close theaccess-opening, whereby the ring-shaped part or rim of the dust collecting memher at the vicinity of the air inlet end thereof can provide a seat for the cover and maintain the latter in its closed position when the cover is removably secured to the casing in any well known manner.
  • a vacuum cleaner a casing having an opening into the interior thereof and a cover for the opening, a dust collecting member through which air is adapted to pass, said dust collecting member normally being posilioned in the-interior of said casing within said cover,
  • positioning means providing a seat for retaining said dust collecting member in its normal position, said cover being movable into the interior of said casing past said positioning means when said dust collecting member is withdrawn from said casing, and means including said dust collecting member, when the latter is seated on said positioning means, to provide a seat for holding said cover in position at the opening of said casing.
  • a vacuum cleaner a casing having an access opening, a dust collecting member having a rim part, said member being insertable into the interior of said casing at the access opening, positioning means providing a seat for retaining said rim part in position when said member is disposed in the interior of said casing, a cover for closing the opening, said cover being movable into the interior of said casing past said positioning means when said member is withdrawn from said casing, and means including said rim part, when the latter is seated on said positioning means, to provide a seat for holding said cover in position at the access opening of said casing.
  • said means to provide a seat for said cover includes gasket means for said rim part, said positioning means including an abutment on said casing at which region said gasket means is retained in position when the access opening is closed by said cover.
  • said rim part comprises an element extending about said member which serves as a reenforcement, said element'being clamped between said gaskets when the access opening is closed by said cover.
  • a casing having an opening into the interior thereof and a cover for the opening, a dust collectingmember through which air is adapted to pass, said dust collecting member normally being positioned in the interior of said casingwithin said cover, positioning means providing a seat for retaining said dust collecting member in position, said cover being movable into the interior of said casing past the seat provided by said positioning means for said dust collecting member when the latter is withdrawn from said casing, and means including said dust collecting member, when the latter is seated on said positioning means, to provide a seat for holding said cover in position at the opening of said casing.
