DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

(6) Referring now to the drawings, the multi-component quick assembly handle of the instant invention is generally designated by the numeral 10. The multi-component quick assembly handle includes a first tubular member 12 made of a permanently deformable material, such as aluminum or other extrudable metal material, for example. Bye permanently deformable it is understood that the material can be subjected to forces which cause it to take on a new permanent shape. The member 12 has a first end 14 formed with a predetermined diameter (x) and connecting to a second end 16 forming a remaining portion of the first tubular member 12 which is a smaller diameter (xa) wherein the first end 14 connects to the second end 16 by way of a tapered section 17. There is also a second tubular member 18 made of a permanently deformable material preferably similar to that described above and having a first end 20 with a predetermined diameter (x) substantially that of the first end 14 of the first tubular member 12 and connecting a second end 22 forming a remaining portion of the second tubular member 18. The second end 22 has a larger diameter (x+b) and an inner diameter (y) slightly larger than diameter (xa) which is to complementary receive by way of a friction fit the second end 16 of the first tubular member 12. The first end 20 connects to the second end 22 by way of a tapered section 19. At least one of the first ends, 14 or 20, e.g., 14 has a connector 24, e.g., which can be a press fit threaded connector, for connecting a cleaning head 26, such as a mop or broom, to form a cleaning implement. The connector 24 piece does not necessarily require a thread, for example, in the case of a broom the connector 24 can have an end wound directly thereto or a piece of mop hardware could be riveted on thereto. Additionally, there can be provided an end plug 29 with an eyelet for present into the bother end 20 or 14 for permitting hanging and storage of the cleaning implement.

(7) A method of forming multi-component quick assembly handle 10 is also provided. The method includes the steps of providing a first tubular member 12 and a second tubular member 18 of a first predetermined inner diameter (z) and a second predetermined outer diameter (x) wherein the tubular members 12 and 18 are made of a permanently deformable material, such as that previously described. The method further provides a female forming tool 30 having a female forming end 32 including a terminal portion 34 of a diameter (zd) smaller than the inner diameter (z) and a section 36 having a maximum outer diameter (z+e) slightly larger than the first inner diameter (z) which connects to a remaining portion 38 of the female forming tool 30 and wherein the female forming end 32 is inserted into end 22 of the second tubular member 18 under pressure to permanently deform into female end 22 of the second tubular member 18. It is understood end 54 of intermediate tubular member 50 can be similarly formed.

(8) Further, the method includes providing a male forming tool 40 having a male forming end 42 having an opening 44 with an entry inner diameter (ze) larger than the outer diameter (x) of the tubular members 12, 50, and 18 and an inwardly disposed inner diameter (zd) which is slightly smaller than diameter (zd) of the female forming tool 30. When the male forming end 42 receives under pressure end 16 of the tubular member 12 it permanently deforms end 16 to have outer diameter deformed complementary to be friction fit received into the female end 22 of tubular member 18. It is understood end 52 of intermediate tubular member 50 can be similarly formed.

(9) The formed male end 16 and female end 22 are of a minimal tolerance to cause the same to become substantially permanently connected when press fit to each other. The method further includes providing cleaning head 26, such as a mop or broom, providing cleaning head connector 24 and connecting the same to end 14, for example, to form a cleaning implement.

(10) By so providing, the instant invention, there is an advantage in that the tubular members 12, 50 and 18 enable the connection to become substantially permanent press-fit where they are put together only once. The interconnectable tubular members 12 and 18 members enable the shipment in a smaller box. The very popular Swiffer is an example of existing cleaning implement wherein the instant invention can provide an improved multi-piece handle that is easy to put together but nearly impossible to take apart all while being easily shipped.

(11) It is contemplated that there can be more than two tubular members, such as three, four or five members, in which case interconnecting set of ends can be similarly formed to that described above and as such the middle tubular member would have both ends modified to have any combination of male/female ends. FIG. 5 depicts intermediate tubular member 50 having a similarly formed smaller end 52 and enlarged end 54. The end 52 connects to an intermediate section 56 by way of a tapered section 53 and The end 54 connects to an intermediate section 56 by way of a tapered section 55. Thus, if a 60 inch handle is desired, it could be made of four 15 inch, three 20 inch or two 30 inch pieces to make a 60 inch which is the standard length for may cleaning tools. So, a 24 inch push broom could come with three 20 inch pieces in a compact 24 inch shipping box.

(12) A use of the invention can be for lobby dust pans, where all handles are currently desirably 30 inch and prior hereto required a 30 inch long box. The dust pan may be only 15 inch and with the instant invention two pieces about 15 inch long can be employed so that the lobby dust pan and handle would fit nicely into a box which is about 15 inch long saving both box cost and shipping costs and storage space costs.

(13) Other modifications, derivations and improvements will be readily apparent to those skilled in the art. Accordingly, the appended claims hereto should be afforded the coverage of such modifications, derivations and improvements.
