fig1 shows the top view of the crevice tool where it can be seen that there is a tapered male end 1 at one end , transitioning into the flat air chamber or of the crevice tool 2 , through which debris laden air will pass from the suction slots 4 and 6 , through the tapered male end 1 of the tool , and into the vacuum cleaner to which it is attached . fig2 illustrates the nubs 5 protruding from the top and bottom surfaces of the crevice tool 2 , which , when raked over a debris ridden surface , will dislodge said debris and , using the air movement caused by the vacuum cleaner through suction transferred to the suction slots 4 and 6 , will become air born in the immediate vicinity from where the debris particles were dislodged , causing said particles to move into the air chambers and consequently be removed from the areas being vacuumed . fig3 illustrates the air slit 6 at the end of the invention and an end view of a support rib 7 extending lengthwise inside the air chamber . not previously mentioned , the supports ribs assist in keeping the airway open for free - flowing , debris laden air , and create the individual air chambers 8 for each set of slots . fig4 shows a top cutaway view of the invention where it can be seen that there are individual air channels 8 leading from the air slots 4 and 6 to the body of the crevice tool 2 , created by the support ribs 7 . these individual air channels work to equalize the suction provided to the suction slots . as previously stated , the concept of this invention is to provide a tool for use in vacuuming , where the tool can be applied within tight and confined areas , such as a crevice , or even under a refrigerator , or the like , and not only can roughen up the area , so as to loosen any accumulated dirt or dust , but then function to vacuum up the loosened debris , during the vacuuming process . this particular aspect of the crevice tool can be seen in fig5 and 6 , which includes an adaptor 9 which has a widened configuration at its upper end 10 and which is capable of attachment to the standard vacuum cleaning accessory , usually the length of tube that extends down towards the end where other accessories are applied . the adaptor then continues into a transitional area , and it &# 39 ; s angulated , as at 11 , and then reasonably flattens , as at 12 , into the configuration as noted . the adaptor , at its flattened end 12 , is then capable of cooperating with an extension 13 , the crevice tool 2 or the “ paw ” 19 , as noted in fig7 . the extension is designed to provide for insertion of the crevice tool deeply between and into confined spaces , as can be understood . the flattened end 12 of the adaptor accepts the insertion of the other three components into a corresponding end , as can be seen . the extension 13 may include reinforcement , as at 15 , internally along its length , either by formed ridges , or a length of integrally molded reinforcement means , to maintain the separation of the flattened extensions 13 , as can be noted . obviously , the extension 13 has at least one channel , internally , as at 16 and 17 , for the vacuumed debris to enter therein and pass therethrough , during usage of the vacuuming device . the opposite end of the extension , as at 18 , is of a reduced dimension , as can be noted . the reduced dimension provides for its insertion or interconnection with the terminal end of the crevice tool , as to be subsequently described . as can be seen in fig9 , the reinforcement means , as at 15 , can be seen at the reduced end 18 for the extension 13 . obviously , the reinforcement may be a midpoint wall that extends the length of the extension , or it may be a series of post , molded along its length , that simply provides a reinforcement to maintain the spacing between the upper and lower walls for the extension , during its usage , and to minimize the chance that the extension can be crushed , or pulled by vacuum force into closure , which would be undesirable for the operations of the crevice tool during usage for a vacuuming operation . fig1 shows a terminal end 19 for the invention . as noted , it does have a paw like configuration , and has a reduced end , as at 20 , which can slide into the female end 18 of the extension , when the entire tool is assembled for usage . then , the end 19 is widened , and affords a series of openings , as at 21 , into its interior , that allows for the sucking up of any debris into the terminal end , through the extension , and its adaptor , and into the vacuuming device for disposal . there may be a series of projections , some as shown at 22 , that may be provided upon the upper surface , or the lower surface , or both , of the terminal end 19 . these projections can also be provided over the entire surfaces of the end , for the purpose of abrasively rubbing against any debris , dust , or other accumulated dirt , that needs to be loosened , and to keep a separation of the openings from flat surfaces to give room for air flow so that the vacuuming device can absorb the loosened dirt into this terminal end 19 , through its apertures or ports 21 , when vacuuming dirt during usage of the vacuuming device . fig1 shows a backend view of the terminal end 19 , and shows the reduced end 20 , and how it leads into the hollow interior of the end 19 , so as to provide for a vacuuming thereat , to draw debris into the end 19 , during operations of the vacuuming means . in addition , there may be reinforcement within the end 19 , that may provide for maintenance of the spacing between the upper surface 23 and the lower surface 24 , of the end , to assure that it is maintained opened , and can attract and draw the removable debris from the area being vacuumed , through the terminal end , the extension of the tool , its adaptor , and into the vacuuming device . therefore , it will be understood that the present invention should be interpreted in a broad manner , its breadth being determined only by the terms of the claims . obviously , variations or modifications to the subject matter of this invention may occur to those skilled in the art upon review of the summary as provided herein , and upon undertaken a study of the description of its preferred embodiment . such variations , if within the spirit of this invention , are intended to be encompassed within the scope of any claims to patent protection issuing hereon . the description of the preferred embodiment , in view of the drawings , is set forth for illustrative purposes only .
the present invention refers to a crevice tool for vacuum cleaners as a singular component , comprising a socket transitioning into a long , flat air chamber , at an angle of approximately 45 degrees , wherein the air chamber incorporates both air suction slots and protruding nubs on both the top and bottom of the tool , and lateral slits in the end opposite the socket end . the various components of the crevice tool may be fabricated into kit form , and may include an adaptor , an extension , and a paw like terminal end , that can be used for removing any debris from tight areas .
