Abstract
A vacuum cleaner attachment system for cleaning narrow spaces having a flattened suction attachment tool (11) removably connected by one or more flattened extension tubes (12) to a flattened-to-round adapter (14) attachable to conventional circular cross-section vacuum cleaner suction hoses, the parts being releasably held together by manually operable detents (21
Description
- This invention relates to vacuum cleaner attachment systems, and more particularly to systems using extension tubes between the cleaning tool and the vacuum cleaner hose.
- Systems for removably attaching tools to a vacuum cleaner hose are well known in the prior art. All of the "tank type" vacuum cleaners currently on the market, and some of the "upright" vacuum cleaners, utilise flexible hoses to provide suction at positions remote from the vacuum cleaner to afford better accessibility to such locations. Many of today's vacuum cleaners use extensions of various kinds for increasing the reach of the hose, with the suction tool being releasably mounted on the end of such extensions so that they can be replaced with other tools.
- It has also heretofore been known to provide narrow, elongated suction tools for removing dust and dirt from narrow places see, for example, United States Patent 4,332,051 and the patents cited during the prosecution thereof.
- However, each of the prior art patents known to the applicant is narrow over only a portion of its length and then bulges outwardly to a circular cross-section adapted for connection to the end of a vacuum cleaner hose. Many times the operator of the vacuum cleaner desires to clean narrow spaces of a length too great to be reached by conventional flattened end tools as, for example, the space beneath a refrigerator or stove. Dust, lint and other debris accumulate in such spaces and cannot be removed by presently known vacuum cleaner attachments.
- The applicant is also aware of the following U.S.A. patents which have relevance namely:
- U.S.A. Patent 1,403,524
- U.S.A. Patent 1,694,257
- U.S.A. Patent 2,276,078, and
- U.S.A. Patent 2,789,307.
- The vacuum cleaner attachment system of the present invention makes it possible to clean narrow, deep spaces which have heretofore been unreachable by conventional vacuum cleaner tools. This is accomplished in the present invention by a flattened tool which can be fully inserted into the narrow, deep spaces. The effective length of the tool is selectively increased or decreased at the will of the user by interposing flattened extension tubes between the attaching end of the tool and the flattened end of a round-to-flattened adapter capable of being mounted on the end of a vacuum cleaner attachment hose.
- Each flattened extension tube has a receiving end formed for telescoping engagement over the flattened end of the adapter and an opposite insertion end formed for telescoping reception within the attachment end of the flattened tool. Since the receiving ends of the flattened extension tubes are all of the same size and configuration, as are the insertion ends, as many of the flattened extension tubes as may be desired can be interposed between the adapter and the flattened tool.
- The different parts of the system are held together in the described telescoping engagement by manually operable detents on the insertion ends releasably engageable in openings formed in the receiving ends.
- It is therefore an object of the present invention to provide a vacuum cleaner attachment system capable of cleaning long and deep narrow spaces between adjacent objects without requiring that the objects be moved.
- Another object of the present invention is to provide a vacuum cleaner attachment system of the character described which may be readily lengthened or shortened to adapt the system to differing sizes of narrow spaces to be cleaned.
- A further object of the present invention is to provide a vacuum cleaner attachment system of the character described in which the various parts are held securely together for operation, but which can readily be manually detached from each other and parts removed or additional parts added.
- To enable the nature of the invention to be fully understood, a particular and at present preferred embodiment of the same is hereafter described by way of non-limitative example with reference to the accompanying drawings, in which:
- Figure 1 is a perspective, partially exploded view of a portion of a vacuum cleaner attachment system constructed in accordance with the present invention:
- Figure 2 is a plan view on an enlarged scale of a flattened extension tube forming part of the vacuum cleaner attachment system of the present invention and shown in operative association with fragmentary portions of other elements of the system illustrated in chain-dashed lines:
- Figure 3 is a side elevational view of the flattened extension tube of Figure 2;
- Figure 4 is an end view of the flattened extension tube of Figures 2 and 3;
- Figure 5 is a vertical cross-sectional view on an enlarged scale of a telescoping engagement and detent means illustrating how the parts of the vacuum cleaner attachment system of the present invention are releasably secured together:
- Figure 6 is a plan view of a flattened suction cleaning tool forming part of the system of the present invention; and
- Figure 7 is a vertical cross-sectional view substantially on the plane of line 7-7 of Figure 6.
- While only the preferred form of the invention is illustrated in the drawings, it will be apparent that various modifications could be made within the ambit of the appended claims.
- As may be seen in the accompanying drawings, the vacuum cleaner attachment system of the present invention provides a flattened
suction attachment tool 11 having a width substantially greater than its height, aflattened extension tube 12 removably attachable to anend 13 of thetool 11 and likewise having a width substantially greater than its height, and anadapter tube 14 having aflattened end 16 attachable to anend 17 of theflattened extension tube 12 opposite to thetool 11, theadapter tube 14 having a substantiallycylindrical end 18 opposite theend 16 formed for removable attachment to a vacuum cleaner hose (not shown). - For ease of manufacture, the
flattened attachment tool 11, theflattened extension tube 12 and theflattened end 16 of theadapter tube 14 are shown to be of substantially rectangular cross-section commensurate in size, with the width of the rectangular cross-section being over three times its height. - In accordance with the present invention, the
flattened attachment tool 11, theflattened extension tube 12, and theadapter tube 14 are releasably securable to each other by forming anend 17 of-theextension tube 12 to telescope over theflattened end 16 of theadapter tube 14, and by forming the attachingend 13 of theflattened tool 11 to telescope over theinsertion end 19 of theextension tube 12, the parts being releasably secured together when telescoped one on the other bydetent means 21. - The
detent means 21 is provided by making theend 16 of theadapter tube 14, and theend 19 of theflattened extension tube 12, both of which telescope within receivingends bevelled protuberance 22 is formed on one or both sides of theends detent openings 23 formed through thereceiving ends detents 22 with theopenings 23 is assured by positioningshoulders 24 formed on theends - As will be apparent,
insertion ends ends end 16 can be received in theend 13 of theflattened tool 11, or it can equally well be received in theend 17 of theflattened extension tube 11. Likewise, theinsertion end 19 of theflattened extension tube 12 can be received in theend 13 of theflattened tool 11 or in the receivingend 17 of anotherflattened extension 12. Thus, by interposition or removal of theflattened extension members 12, the effective length from theadapter 18 to the outer end of theflattened tool 11 can be increased or decreased as desired. - While any suitable flattened tool may be used in the vacuum cleaner attachment system of the present invention, the tool configuration illustrated in Figures 6 and 7 of the drawings functions particularly well. As there shown, the
tool 11 is shaped similarly to the flattened portion of an ordinary vacuum cleaner crevice tool, that is, with the height and width of the tool tapering down toward theouter end 26 in the manner illustrated in Figures 6 and 7 of the drawings. Theouter end 26 is bevelled at 27 in the manner shown in Figure 6 of the drawings and thetip 26 is open. - An
opening 28 controlled by a sliding door is formed through oneflat face 29 of thetool 11, and a comparativelyflat brush 31 is mounted around the opening 28 to stir up dust and debris sufficiently for them to be drawn into thetool 11. - From the foregoing, it will be seen that the vacuum cleaner attachment system for cleaning narrow spaces of the present invention, and as described above, provides a novel approach and facility for cleaning those deep and narrow spaces beneath stoves, refrigerators, and the like, and other similarly heretofore inaccessible spaces.
