The present invention relates to attachments and accessory tools for surface cleaning appliances such as vacuum cleaners, and more particularly to an accessory tool with a dusting brush with a base ferrule and including a telescoping extension attached to a flexible mount base, and an ergonomic handle configured for either finger or full hand gripping, and an independent adjustable accordion hose attachment with a grip end and an ergonomically superior handle.
Surface cleaning appliances such as vacuum cleaners for cleaning floors, upholstery, and other surfaces in a home or workplace are generally known in the prior art. The most popular household vacuum cleaners are either upright standing or canister style vacuum cleaners, although other more specialized types such as handheld vacuums, central air vacuum systems, electric brooms, and shop vacuums are also available. Household vacuum cleaners typically include a primary electrically motorized surface cleaning component which includes a spinning rod having a series of affixed stiff bristles segregated in individual circumferential rows to create a rolling brush for cleaning floor areas such as rugs or hard floor surfaces by repeatedly passing the surface cleaning component across the surface to be cleaned in a generally back and forth motion, whereby dirt and debris is collected into a bag or receptacle by a suction force created by a vacuum unit. Canister style vacuums allow for the handle to detach from the surface cleaning component and then be attached to other cleaning attachments. The canister handle is attached to a flexible extension hose that is attached to the vacuum unit. Most upright vacuum cleaners are equipped with a separate flexible extension hose that is connected independent of the surface cleaning component. Both the canister style vacuum handle and the upright vacuum flexible hose end with a rigid coupler hose for attaching various vacuum attachments such as rigid extension hoses and/or purposed cleaning attachments that are designed to clean those areas that cannot be cleaned by the primary roller brush component used for flooring.
There are many vacuum device attachments on the market today which vary in shapes and sizes to accommodate various cleaning projects. For instance, a crevice tool can be used to clean between cushions and in another instance a stiff bristled brush tool is used to vacuum debris from the top surface of a cushion. The present invention, however, is primarily concerned with those attachments that are used for dusting surfaces which require detailed cleaning such as statues, knick-knacks, computer screens and keyboards, and the like, which typically do not conform to standard shapes. There are limited attachments available for intricate dusting purposes. Rigid extension hoses are also available which are placed between the vacuum's flexible hose and an attachment to reach further areas out of reach. A common problem that occurs is that upon the purchase of a vacuum machine the assortment of attachments provided do not cover all the cleaning needs of a home or workplace, especially for the purpose of dusting in a comfortable and thoroughly complete manner. To fill the various cleaning needs, the consumer therefore must purchase additional vacuum attachments that are more applicable to their specific cleaning chores. These additional purposed vacuum attachments may be purchased either from the original vacuum manufacturer or a similar or better designed vacuum attachment may be purchased from a different manufacturer.
When close up or distant dust cleaning is required, currently available attachments on the vacuum market do not meet the basic dusting needs of the consumer. Especially for close up dusting, a consumer usually resorts to the old fashioned method of dusting by hand by the employment of the use of a feather duster and/or a rag, since the available vacuum dusting attachments are too bulky, or odd shaped to fit in particular spaces and/or the difficulty of directing the aperture opening over the area to be vacuumed, especially when dusting delicate and intricately shaped items. In addition, most of the available attachments on the market today are rigid throughout the whole of the attachment where a flexible area, if included, is usually in one location only, limiting directional movement of the vacuum attachment. An example of this would be an attachment that reaches under furniture, where the attachment bends only at one point so as to allow the attachment to flatten out so the consumer does not have to lay on the floor to guide the direction of the attachment. Most vacuum attachments are usually fixed in a set or limited radii positions once affixed onto a rigid extension hose, and when affixed to a flexible vacuum hose, a comfortable grip for the hand is lacking, thus taxing the consumer's hand, wrist, and so forth, limiting the flexibility of cleaning as well as limiting the ability of the consumer to reach specific target areas to be cleaned with a delicacy required for dusting delicate and/or awkward areas such as inside shelf corners, statuettes, decorative plants, intricately designed lamp bases, around exterior surfaces and disk intake ports of stereo equipment, Venetian blinds (especially around the vertical slate holding strings), computer keyboards, computer tower air vents, and such. Some attachments are so unwieldy as to be of little use at all, having no handle to grasp and as a result usually requiring the consumer to expend too much effort of using their hand, wrist, or body maneuvering while they endeavor to accomplish the same chore that ends up being easier to accomplish with a rag or feather duster. Much time is also expended in changing various different attachments while seeking the desired cleaning effect. Since the feather duster and/or a rag while dusting usually just re-spreads the dust back into the household air, the dusting chore is short lived as this newly disturbed air-borne dust simply resettles upon other surfaces. Sometimes a consumer will try to use both the vacuum and a feather duster or a similar duster by leaning the open vacuum hose near the area to be dusted hoping that the newly released air-borne dust is transferred into the vacuum receptacle. The consumer is already burdened down by having to carry around specific purposed cleaning attachments, rigid extension hoses for distant out of reach areas, and then is further burdened by also carrying around additional feather dusters, rags, and such, with their accompanying cans/bottles of spray and liquid cleaners.
The consumer encounters further problems with vacuum attachments especially with grasping the wand and/or the attachment when attached together. Since to the knowledge of the inventor a comfortable handle to grasp is not included on most attachments, any time an attachment is affixed to a corresponding hose, the hand is forced to endure the uneven crack formed between the two attachments so as to use the wrist to guide the attachment in the desired direction. The consumer therefore resorts to holding the rigid wand, or the uneven connected site area, especially when using the flexible hose and rigid coupler hose extending out of the upright vacuum cleaner. Even though the canister vacuum's flexible hose ends in a handle before an attachment is affixed to the rigid coupler hose, the consumer's use of the canister vacuum handle will find that the grip is usually oversized, awkward, and on the heavy side, due to the handle's original intent of use for directing the path of the main motorized primary surface cleaning component, and not necessarily designed to enhance nor being convenient to use with individual affixed attachments. So using either the upright or the canister vacuum cleaner, the consumer encounters physical discomfort while trying to dust. Many modern consumer devices, from kitchen utensils and so on, have a handle which is made to fit comfortably in the user's hand, and are made of a soft thermal plastic rubber (TPR) material, hard silicone, or a combination of other hard and soft materials. Such comfort handles are beneficial to all users and particularly to the many individuals that suffer from carpel tunnel syndrome, osteoarthritis, and other painful maladies of the hand, wrist, arms, and back. In addition to a softer and a more comfortable grip handle devices offered in other markets, they are also sometimes manufactured with grip-like protrusions so the user has in their possession a slip resistant article, which is invaluable when a cleaning chore produces sweat on the individual's hands. There is therefore a need for a vacuum attachment tool that can be used to easily and effectively pick up dust and small particles which has an ergonomic and comfortable handle which makes holding and manipulating the device easier in a more effective manner, while also being able to move in a specific direction when needed.
Another problem with vacuum dusting attachments is that for the most part there is nonexistent or inadequate lighting incorporated in the individual attachments themselves which would facilitate seeing the dusting area to be cleaned, especially areas that are in shadow such as behind other items on a shelf, or the lighting due to the time of day. Usually only the motorized primary surface cleaning component is complemented with lighting to light up the area in front of it to be vacuumed, but it would be especially an advantage to have peripherally overall lighting on an attachment to be able to see all surrounding areas that are being vacuumed, thus speeding up the cleaning process. The obvious advantages of including lighting on an attachment itself are twofold, as it lights up the area to be dusted, as well as the emitted lighted beams allow the consumer to actually see and confirm that the dust nodes are being sucked up into the vacuum attachment. Unfortunately, because of the lack of proficient lighting on vacuum attachments, a consumer might devise to precariously place a lamp closer to an area, or employ the uncoordinated use of a flashlight to obtain the same results.
As aforementioned above, rigid extension hoses become unwieldy and heavy to maneuver while using an attachment at their farthest end. Additionally, rigid extension hoses are of a determined length. When a consumer needs an attachment to reach a distant area to be cleaned, one rigid extension hose might be too short which might necessitate the consumer to stand dangerously on ladders or furniture. When additional rigid extension hoses are added to reach the target area, the hose length might be over-long causing the consumer to then move furniture out of the way so as to be able to move backwards. If unmindful while focusing on the distant vacuum attachment while cleaning, there is the possibility of the consumer tripping and falling backwards over furniture, or even falling backwards down stairs. Besides trying to match the distance required, the consumer will become frustrated further trying other various ways of focusing the rigid vacuum attachment's aperture opening to the target area using the inflexible and unbendable rigid extension hose.
Accordingly, it is the intention of the present inventor to provide an improved lightweight, handled equipped vacuum dusting attachment and a flexible lightweight independent accordion hose vacuum attachment. In the preferable mode, the vacuum dusting attachment device includes two sections, a cleaning portion and a handle portion, which together could be made of several parts or of a singular part. The accordion hose attachment would replace rigid extension hoses and includes handles on both ends for holding, extending, collapsing, and bending the hose to desired shape and length to reach cleaning target areas while supporting the weight of aforesaid attachment or other types of attachments.
In accordance with the present invention featured in the drawings, there are two sections that make up the vacuum dusting attachment device: a cleaning portion and a handle portion. The cleaning portion includes a paint brush-style head, usually referred to as a “mop” brush in the painting artists' market, and similarly, the hairs on one end of the brush are enclosed in a metal ferrule which holds the bristle hairs in place. There are dusting appliances where the open apertures are placed between or centered within the hair bristles or feather-like extensions, but a concentrated mass of bristles creates increased friction upon surfaces to be cleaned as well as being able to access smaller surface areas. In the preferred embodiment, the ferrule includes an extended lower section which becomes part of a telescopic extension to obtain further detailed cleaning length choices, but the product could be devised without a telescopic feature. The mop brush and ferrule/telescope is attached preferably to a semi-flexible mount, which becomes an axis point allowing a pivotal sway of the mop brush head as it contacts items to be cleaned, saving the consumer from extra hand movement. The base, or end of the telescoping extension in an embodiment is a solid pin inserted and affixed to the internal sides of the semi-flexible mount which is made of a flexible material like, but not limited to, rubber that equals the length of the pin of which both could end at the top and affixed to the open apertures disc, but preferably the telescopic solid pin encased with the rubber mount material can be extended and inserted into and through the center of the disk and extend beyond with supporting ribs and possible extensions from those ribs, include bendable wiring to insert into pockets formed in the interior of the neck in the injection molding process. The disk-like portion has open aperture holes purposed to draw in dust particles that the brush head dislodged or “brushed off” while in the process of dusting. Peripherally surrounding the open apertures disk are light bulbs, or any other sort of functional lighting type source, provided to assist in the visual efficiency of the vacuum dusting attachment while dusting, as well as to be able to see the dust nodes being collected by the aperture holes. In the preferred embodiment, the lights would encircle the disk-like area, so the area to be dusted would be circumferentially lighted, but the lights are not limited to this placement. The accompanying Figures are used for description purposes and do not limit the possible shapes, sizes, and placement of the individual pieces of the forward portion of the cleaning portion of the vacuum dusting device. For example, the open apertures could be square, or even a screen, etc.
Behind the brush/telescope dust gathering “disk-like” portion and lights, the cleaning portion of the vacuum dusting attachment narrows into a hollow neck area that is made so as to provide a soft and cushioned area where the consumer can hold and direct the device in essentially the same manner that a painter may hold a paint brush, or a writer holds a pen, giving extreme detailed control while in the act of dusting. This neck area may be made of a material such as a soft bendable plastic, or even a hard silicone rubber of which it could further be devised that bendable wire/s could be inserted or molded within the narrow neck walls of the device allowing this finger hold area to be bendable in different directions allowing the device, and not the consumer's hand to do the bending for awkward and hard to reach target areas. Internally this narrowing of the neck will also concentrate the vacuum suction of which would increase the drawing power of the open apertures.
Referencing again to the neck area of the cleaning portion of the vacuum dusting device, continuing from the narrow finger hold area located just behind the aperture/light disc, the neck area circumferentially widens, and just short of where the handle portion begins, a battery chamber is inserted. If batteries are the choice, the smallest available would be used, and the wiring from the battery chamber would connect to a bulb which then connects to a continuing string of lights. There are other sources for the lighting system such as solar power and so forth which would be determined during manufacturing. Quite possibly a charging pin port could be incorporated on the vacuum dusting device whereby the lights/battery/s are charged on a specially designed vacuum unit itself and/or a wall charging station which would have complimentary charging ports. The battery chamber would be covered externally on the surface by a soft airtight push on/off switch. The exterior off/on switch button would be soft and flexible so as to push on and off, and be located in an area so as not to cause the consumer discomfort in the use of the device, yet conveniently located to activate. If a battery and wiring system is to be used, then it would be desirable that a portion of the dusting device be able to be opened, or have a sufficient opening end, so as to repair, replace, etc. the wiring system.
Also on the surface of the neck area, there is room to add a vacuum suction control to increase or decrease incrementally the vacuum suction, which gives more control to the consumer to vacuum delicate items. One vacuum suction control option would be to place a circular or circumferential piece with an opening to correspond with an opening on the device itself, so when spun around the hole on the device, the vacuum suction is controlled by opening and closing to desired increments. Another control option would be to provide a sliding door over the open hole in the device which accomplishes the same. The location of the suction vacuum control on the device will be chosen so as not to interfere with the operation or comfort of the device by the consumer.
The handle portion of the vacuum dusting device is designed as a conduit for vacuum suction but is shaped ergonomically for the consumer's hand to hold the device in comfort. As with other vacuum attachments, the open nozzle end will frictionally attach to the independent accordion hose vacuum attachment, the flexible hose coupler deriving from the vacuum unit, or other various extension hoses. The coupling ends of both the vacuum dusting attachment and the accordion hose vacuum attachment will ideally be manufactured as closely as possible to be able to couple with the current vacuums on the market today, but due the manufacturing specification varieties between manufacturers, a coupler might be needed, but a dedicated vacuum machine and an assembly of corresponding attachment parts could be devised as well, and if so, it might be an advantage to incorporate a complimentary single or double threaded screw ends on each device to prevent separation of the devices while cleaning. However the coupling of the attachments are devised, it is apparent that having the handle end to have an internal coupling nozzle as opposed to an external and protruding coupling end will further lighten the weight of the attachment overall.
The portion of the handle which the hand grips is ergonomically shaped for comfort and is coated in a soft, possibly even padded-like material, while the interior would be a more substantial rigid material which would retain the handle shape and support the end nozzle for friction coupling with the accordion hose or other hose/wand attachments. Protruding upwards, or engraved upon, and around the handle area are bumps and ridges which provide a better grasping grip area, especially when the hand becomes sweaty. These bumps and ridges could be created in the manufacturing process of the soft outside coating of the handle, but consideration should be given in materials chosen in the manufacturing of the attachment overall so as to keep it lightweight and balanced throughout.
The independent adjustable accordion hose extension vacuum attachment with a grip end and a ergonomically designed handle, of which is the same handle used on the paint brush vacuum device, would replace the use of, or in conjunction with rigid extension hoses currently used when trying to reach distant target areas and would ideally be made with, but not limited to, a plastic which would be sturdy enough so as not to collapse from the vacuum suction, yet flexible to shape and maintain a bend chosen in the desired direction with ease, and easy to extend and collapse, yet lightweight. The material chosen for the accordion hose device would ideally withstand repeated usage without cracking. The hose provides a lighter and easier accessory to use than a rigid extension hose and has its own handle to use while directing the vacuum dusting device towards a distant target area. If more accordion hoses are stacked together for extended length, there is always a handle close to the consumer to grasp. With the ability to expand and collapse to any distance desired within the realm of being total collapsed and the full extension of its manufactured limitations, it makes reaching target areas to be cleaned more manageable and flexible, especially with its ability to be bent by the consumer in any direction desired. Because the bellows of the accordion hose will be manufactured specifically to a hard thickness which won't collapse from the vacuum suction, the total expanded opened length should be manageable by a consumer, where a full extension of the hose should match the width of a standard consumer's width of the arms, approximately two feet. If additional distance is required, another accordion hose device could be attached, or as many as the consumer needs, since all the described vacuum attachments within the scope of the invention are coupler compatible, but other hoses and such could also be used, even if another manufacturer's adapting coupler is required. The accordion hose vacuum attachment's disk grip and the handle of which is the exact same handle used on the vacuum dusting device, are placed at the ends of the accordion portion specifically for making it easier for the consumer to pull out and expand the accordion hose, for pushing in to collapse the accordion hose, and bending the accordion hose. Another version of the accordion hose vacuum attachment may have the disk grips on both ends, and/or a smaller handled coupler. Although the exterior of the handle will be ergonomically shaped, the internal hollow tube of the handle would be straight for coupling and for facilitating straight suction direction projection. The other advantage is that the accordion hose portion collapses approximately a third of its fully extended length which makes it beneficial for storage and for carrying the accordion hose device around.
The grip disk of the accordion hose vacuum attachment is located behind the protruding coupling nozzle end that is inserted into another vacuum device and before the accordion hose begins, and is made of a sturdy material but is coated with, but not limited to, a soft material such as TPR with the raised bumps and/or ridges similar to the handle on the vacuum dusting device's handle so as to provide a comfortable and ergonomic grasping handle for the consumer. This coating would cover both sides of the disk and continue towards the accordion hose as its circumference decreases down to match the width of the accordion hose.
The accordion hose device is attached between a vacuum dusting attachment device and the vacuum cleaner output hose, or other hoses attached to the vacuum cleaner. When the consumer prefers to hold the handle of the vacuum dusting attachment device for close up vacuum cleaning chores, leaving the accordion hose device/s attached allows the consumer freedom of movement, swing action, and expansion and reaching distance behind them, as well as flexibility of movement of the dusting attachment as opposed to a rigid extension hose. Even though the upright vacuum cleaner has a flexible output hose derived from the vacuum receptacle, adding the independent accordion hose attachment will add additional flexibility and maneuverability for the consumer while using a dusting attachment, and significantly increase the distance from the vacuum cleaner to the area to be cleaned. When using the accordion hose device with a canister vacuum, a consumer can increase their comfort by attaching the accordion hose device to the overlarge and heavy rigid handle, then dropping the canister handle and taking up the vacuum dusting attachment handle attached to the other end of the accordion hose for improved flexibility, comfort, and added distance while using the vacuum dusting attachment for close up cleaning.
It is planned that the vacuum dusting attachment device and the accordion hose attachment device, and quite possibly a dedicated designed vacuum machine, would be sold together and be accompanied with a convenient carryall bag, or other receptacle, or cart, to carry the devices over the consumer's shoulder, or around the waist, or a unit for wheeling/dragging around, while cleaning. It should also be noted that the vacuum dusting device and the accordion hose device would be compatible for use with other vacuum attachments and hoses, although on some vacuum models an adaptor or a coupler might be needed to connect between different manufacturer's products since many manufacturers in the vacuum industry are not consistent in their measurements. A specially designed vacuum machine and corresponding attachments might also be devised where the specially designed vacuum machine could be so enabled to allow attachments to be manufactured with a strip of coefficient conductive material to relay power to the attachment/s lighting system from the vacuum machine, or the attachments can have compatible pin ports to plug into the dedicated vacuum machine.
The dusting attachment brush head and lighting allows the consumer to be able to dust delicate items such as figurines, intricate nook and cranny areas, keyboards without depressing the buttons, and so forth. The accordion hose device allows the attached dust attachment or other vacuum attachment to reach incremental distances and awkward bends to reach specific items and parts thereof.
The overwhelming purpose of the present invention it to provide a lightweight, comfortable, and effective dusting apparatus that is easy to use by the consumer. Although a handle is unique for vacuum attachments and an advantage especially for close up cleaning, it may also be advantageous for the invention to be alternatively manufactured in several parts so as to be more practical for use when long distance cleaning is required, allowing a straight directional line to the area being cleaned while also minimizing total weight of the assembled unit. In this embodiment, the handle would be separate or independent from the cleaning portion, a shorter handled coupler would be provided, and the accordion hose would feature a grip end on both ends replacing the handle on the opposite end.
While the present invention is being particularly designed for use in the vacuum industry, it could be repurposed for the painting industry or other industries that could benefit where the cleaning portion is devised as a non vacuum purposed piece, but is still bendable and possesses lighting, (the mount in this example case would not be flexible) and which would also possess on the top area of the cleaning portion interchangeable telescoping and different shaped and sized paint brush head sizes that could be interchangeable similar to an electric drill's collets and drill bit interchange process, or another interchange method (for example, brush heads could be changed above the telescope, or the brush and telescope as one piece could change out on the disk area), but retain a hollowed ended handle for coupling, then the accordion hose could still be used, and if the hollow ended handle and/or incorporated an internal thread screw, a telescoping pole which is common on the market today could also be used, and of which this new purposed invention could immensely improve painting techniques and other markets for intricate and long distance painting, within the household and industrial painting market.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The following detailed description is of the best mode or modes of the invention presently contemplated.
