Abstract
A device for attachment to a vacuum cleaner to combine the steps of scraping articles from a surface and removing the resulting debris. The device includes a first end which attaches to a vacuum cleaner. The second end of the device has a substantially rectangular shape. A slot is formed beneath the second end near the opening of the device. The slot has a first width slightly greater than the width of the safety end of a scraping blade. The slot also has a second width slightly greater than the width of scraping portion of the scraping blade. A scraping blade is inserted into the slot so that the scraping edge of the blade extends just in front of the opening of the second end of the device. Articles can then be removed from a surface by the blade. The debris which the results is sucked up through the second end and into the tank of a vacuum cleaner.
Description
- There are many occasions which require surfaces to be scraped. One such occasion may arise when a surface is being cleaned prior to painting, to remove rust, stickers or other debris from the surface to ensure a smooth painting surface. Another occasion often arises when masking tape has been applied to protect a surface. Additionally, it is often necessary to remove stickers from surfaces on which they have been applied. Also, it is often necessary to scrape putty or other adhesive products from a wall prior to painting. Old gaskets are yet another item which are difficult to remove and often must be scraped.
- Utility knives have been designed to perform such scraping tasks. Typically, these are hand held devices in which a scraping blade is inserted. The item is then scraped off the selected surface. However, a problem occurs from the use of the knives or other scraping tools. The tool leaves the debris behind during the scraping process. The debris particles can accumulate around the work area. This is particularly a problem when the scraping causes the debris to accumulate in an inaccessible area.
- This problem normally requires an additional clean-up step. The debris is removed by sweeping or by the use of a vacuum cleaner. Even this is not always successful in removing the debris. The debris often has a tacky surface which may adhere onto other objects. Also, the debris can fall into inaccessible areas that even a vacuum may not be effective.
- Thus, a problem exists in cleaning the debris which occurs during a scraping process. At best, a secondary clean-up process is required and at worst, the clean-up process may not be effective.
- The present invention provides a device for attachment onto a vacuum cleaner. The device provides a tool for combining the operations of scraping articles, such as tape, stickers, paint or other debris from a surface with disposing of the resulting debris. This device is able not only to save time by eliminating the secondary clean-up process but also prevents the debris from accumulating in inaccessible places or contaminating the surrounding surface.
- The device of the present invention includes a tubular body member. The tubular body member has a first cylindrical end which is designed to attach to the hoses of most vacuum cleaners. An adapter is provided if necessary which will adapt this first cylindrical end to other sizes of vacuum cleaner hoses. The second end of the tubular body forms the debris-receiving end. The receiving end is shaped in a substantially rectangular shape. Other shapes can be used if desired.
- A slot is formed in the tubular body member beneath and near the receiving end of the tubular body member. The slot has a first portion having a width slightly larger than the width of the safety end of a scraping blade. A receiving portion of the slot has a reduced width slightly larger than the width of the blade portion of a scraping blade. The slot has an opening approximately perpendicular to the receiving opening to receive a scraping blade.
- The scraping edge of the scraping blade is held in the slot so that it extends in front of the receiving opening of the tubular body member. Thus, as a surface is scraped by the scraping blade, the resulting debris is immediately sucked up through the receiving opening of the body member by the action of the vacuum cleaner and deposited into the tank of the vacuum cleaner.
- An adjusting screw can be inserted into the slot to contact the scraping blade. As the adjusting screw is moved, the contact with the scraping blade causes the angle of the scraping blade to change relative to the receiving opening of the body member.
- Other clamping mechanisms other than the slot discussed above can be used. For instance, a wedge clamping device could be secured beneath the receiving end of the body member. Also, a sliding door could be attached to the receiving end to change the pressure of the suction if desired.
- These and other features will be evident from the drawings and the description of preferred embodiments.
- FIG. 1 is a perspective view of the attachment device of a preferred embodiment of the present invention.
- FIG. 2 is a perspective view of a scraping blade for use the attachment device of FIG. 1.

Scraper attachment 10, shown in FIG. 1 includesbody 20 having tubularcylindrical end 22. Midportions rectangular portion 28.End 30 ofbody 20 includesaperture 32 having a reduced rectangular nozzle opening 34.Aperture 32 extends throughoutbody 20.Lip 40 is formed beneathend 30 and spaced slightly from theedge 36 of opening 34 to formslot 42.Slot 42 includes reducedwidth portion 44. - Scraping
blade 50, shown in FIG. 2, includesedge 52 andhousing 54. The scraping blades are shown as a safety razor blade as commonly used for scraping operations. The present invention is intended to be used with other types of scraping blades as well.Slot 42 ofbody 20 is designed to receivehousing 54 of safety scraping blade with a slight resistance.Scraping blade 50 is inserted intobody 20 as shown in FIGS. 3 and 4. - Tubular
cylindrical end 22 ofbody 20 is designed to be attached to a standard vacuum cleaner hose (not shown). If necessary,adapter 60, shown in FIG. 5 can be used as an adapter between the vacuum cleaner hose and tubularcylindrical end 22.End 62 engages with the vacuum cleaner hose and end 64 engagescylindrical end 22 ofmember 20 or vice-versa. - In operation, once
body 20 has been attached to the vacuum cleaner, the vacuum cleaner can be switched on. The user simply begins scraping. As debris is created during the scraping operation, it tends to ride up scrapingblade 50 towardsopening 34. The force of the vacuum cleaner will suck the debris throughopening 34 and intoaperture 30. The debris will then accumulate into the vacuum tank where it can be easily disposed. - The present invention is thus able to dispose of the debris before it ever becomes a problem. This is especially important when the scraping occurs in an inaccessible area or where contamination from the debris is critical. The present invention is able to solve this important problem by sucking up the debris before it is able to fall into an inaccessible area or contaminate the area. This is even true where the debris may be tacky or have an adhesive which might cling to a surface.
- Another embodiment of the present invention is shown in FIG. 6.
Body 70, identical tobody 20 as described above, includesnozzle end 80, similar to nozzle end 34 described above.Lower surface 82 beneathnozzle end 80 includes a series ofengagement notches 84.Blade holder 90 includes a series of matchingengagement notches 94.Wing bolt 96 threads intohole 86 ofbody 70 to securely clampscraping blade 50 in slot 88. - In another embodiment, shown in FIG. 7, the blade holder is angularly adjustable. Screw100 is threaded into
slot 110 in whichscraping blade 50 is engaged. Adjusting screw 100causes scraping blade 50 to change angles. This allows the angle of the scraping blade to be adjusted to create the optimum scraping and/or fit into an area. - In another embodiment (not shown) a sliding door mechanism fits across the nozzle opening. The suction of the vacuum can then be adjusted as necessary for optimum performance.
- These and other embodiments are considered to be descriptive of the present invention. They are not intended to unduly limit the scope of the claimed inventive concept.
