Definitions
- This invention relates generally to vacuum cleaners and the like, and more particularly to a novel and improved filter bag structure and to a novel and improved structure for mounting such filter bag on the housing assembly of the vacuum cleaner.
- FIG. 1 is a schematic view of a vacuum cleaner with a nondisposable filter bag mounted there ⁇ on in accordance with the present invention
- FIG. 5 is a longitudinal section similar to FIG. 4, but illustrating the filter bag in its mounted position on the vacuum cleaner housing and prior to the installation of the tie strap;
- FIG. 6 is a cross section similar to FIGS. 4 and 5, illustrating the mounted filter bag after the collar is folded back and before installation of the strap;
- FIG. 8b is a plan view similar to FIG. 8a;
- FIG. 10 is a partial, longitudinal section of the second embodiment before the collar is folded back to conceal the stitching and tie strap.
- FIGS. 7, 8a and 8b illustrate a tie strap 42 which is used to permanently secure the collar on the housing 11.
- This tie strap is preferably molded from a nonelastic plastic material, such as nylon and the like, and provides a central band portion 43.
- the tie strap provides a ratchet-type socket 44 at one end and a ratchet or serrated toothed end 46.
- the socket 44 and toothed end 46 are structured so that the toothed end 46 can easily be pressed into the socket, and once located within the socket a permanent connection is provided to form the tie strap 42 into a closed ring.
- the socket end 44 provides two side portions 44a which support two arrays of lateral strap portions 44b and 44c.
- the toothed end 46 is provided with a pro ⁇ jection 49 to assist in installing the tie strap.
- a pliers-like tool is used to install and tighten the strap.
- One jaw of the tool engages the projection and the other jaw engages the ends of the side portions 44a.
- the toothed end 46 is moved along the socket end 44 and the strap is pulled tight.
