Description




BACKGROUND OF THE INVENTION




1. Technical Field




The invention relates to vacuum cleaners. Particularly, the invention relates to a vacuum cleaner bag housing assembly. Even more particularly, the invention relates to a bag housing assembly having a rear bag housing and a bag door, one or both of which is at least partially formed of a semi-rigid flexible fabric material.




2. Background Information




Conventional upright vacuum cleaners typically include a foot portion and an upper handle portion pivotally connected to the foot portion. The foot includes an agitator for agitating or loosening dirt and debris from the floor surface, and a motor-fan assembly which creates a suction for drawing the dirt and debris into the vacuum cleaner through a nozzle. The upper handle portion supports a bag housing assembly and includes a hand grip which is used to manipulate the vacuum cleaner over the floor surface. The bag housing assembly houses a vacuum cleaner filter bag which fluidly communicates with the nozzle to receive and filter the dirt-laden air and emit clean exhaust air.




Various types of bag housing assemblies have been used to house and mount the filter bag. The most popular types of bag housing assemblies are referred to as “soft bag” housings and “hard bag” housings. Soft bag housings are usually manufactured from a fabric, such as a non-woven polyester or a porous vinyl material, to allow the clean exhaust air to flow therethrough. The filter bag is accessible through a zippered opening formed in the soft bag which allows the user to remove and replace the filter bag. These soft bag housing assemblies are lightweight which reduces the total weight of the vacuum cleaner, and are formed from a deformable non-scuffing material which will not damage furniture in the event the vacuum cleaner accidentally comes into contact therewith. Further, the air permeable soft bags provide an additional layer of filter material which is capable of filtering some particles which may escape the filter bag.




Hard bag housings are typically formed from a rigid plastic such as ABS or polystyrene and include a rear bag housing which forms a bag cavity, and a hard bag door which encloses the bag cavity. The hard bag door releasably latches to the rear bag housing allowing the user to remove and replace the filter bag. These hard bag housings provide easy access to the filter bag by merely unlatching and removing the bag housing door, and provide an aesthetically pleasing appearance to the vacuum cleaner.




Although these bag housing assemblies are adequate for the purpose for which they are intended, the need exists for an improved bag housing assembly which combines the lightweight, soft and non-scuffing characteristics of a soft bag housing with the easy filter bag access and aesthetically pleasing appearance of a hard bag housing.




SUMMARY OF THE INVENTION




Objectives of the present invention include providing an improved bag housing assembly which is formed of a material which is soft and deformable yet sufficiently rigid to retain a molded shape.




Another objective is to provide such an assembly which is formed of a non-scuffing material which will not damage furniture when contact is made therewith.




A further objective is to provide such an assembly which is at least partially formed of a lightweight fabric which reduces the total weight of the vacuum cleaner.




A still further objective is to provide such an assembly which provides easy access for removal and replacement of the filter bag.




A further objective is to provide such an assembly which provides an additional layer of filtering material to the exhaust system of the vacuum cleaner.




Another objective is to provide such an assembly in which the semi-rigid flexible fabric material is fastened to a rigid frame member to facilitate the attachment of the bag door to the rear bag housing.




These and other objectives will be readily apparent from the following description taken in conjunction with the accompanying drawings.




In carrying out the invention in one form thereof, these objectives and advantages are obtained by providing a vacuum cleaner bag housing assembly movable between open and closed positions, said bag housing assembly including a bag housing which forms a bag cavity for receiving a vacuum cleaner filter bag; a bag door attached to the bag housing to enclose the bag cavity; and wherein one of the bag housing and bag door is formed of a semi-rigid flexible material which is permeable to air and sufficiently rigid to retain a molded shape.

Accordingly, the vacuum cleaner bag housing assembly of the present invention provides a rear bag housing which forms a bag cavity. The bag cavity houses a vacuum cleaner filter bag and is enclosed by a bag door. The bag door is at least partially formed of a semi-rigid flexible fabric material, such as a polyester and preferably a bi-component polyester, which is soft and deformable yet sufficiently rigid to retain a molded shape. The fabric material is non-scuffing so as not to damage furniture when contact is made therewith and is lightweight which reduces the total weight of the vacuum cleaner as compared to vacuum cleaners having solid plastic bag doors. Also, the fabric material provides additional layers of filtration to further filter the exhaust air from the filter bag. Additionally, the rigid plastic frame member which is fastened to the fabric panel, and preferably molded directly thereto, provides a support structure which facilitates the attachment of the bag door to the rear bag housing. The frame member provides easy access to the filter bag for the removal and replacement thereof and provides an aesthetically pleasing appearance to the vacuum cleaner.




Accordingly, the improved vacuum cleaner bag housing assembly is simplified, provides an effective, inexpensive, and efficient device which achieves all of the enumerated objectives. While there has been shown and described herein preferred embodiments of the present invention, it should be readily apparent to persons skilled in the art that numerous modifications may be made therein without departing from the true spirit and scope of the invention. Accordingly, it is intended by the appended claims to cover all modifications which come within the spirit and scope of the invention.
