Description:
This is a continuation-in-part and claims the benefits of U.S. Ser. No. 14/961,200 filed Dec. 7, 2015, now pending. 
    
    
     Background of Invention 
     Field of the Invention 
     The instant invention relates to handles for handle held implements, such as broom and mops and other cleaning tools and long handled tools. More particularly, the invention relates to a multi-component quick assembly permanent handle and method of making same. 
     Related Art 
     There exist many elongated handles for use with mops, brooms and other hand held implements. Typically, these handles are generally cylindrical and have an end adapted with a connector such as a threaded end to be received in a complementary threaded female opening of the cleaning implement. 
     There also exist handles which thread together to extend the length the handles. These type of interconnecting handles tend to be relatively expensive and less fixably stable. The threaded components tend to want to loosen as they are used. Multiple threaded components increases this tendency to loosen. 
     There are also various forms of telescoping handles, where a smaller diameter tube fits inside a larger diameter tube, which limits the places an attachment can be added—such as a clip. The telescoping handles have a means for setting the handles at a certain length. These handles are more expensive and almost always become loose over extended use and are limited to the size of the box they fit in as each piece must fit inside another. 
     There are many expensive multi-piece handles which when assembled, are never disassembled. The purchaser has paid for a feature he doesn&#39;t need. Accordingly, there remains a need to provide a more economical, quickly assembled and substantially fixable interconnected handle. The invention meets the desired need to improve interconnected handles. 
     SUMMARY OF THE INVENTION 
     It is an object to improve handles for hand held implements. 
     It is yet another object to improve multi-component quick assembly handle and method of making same. 
     It is still another object to improve a method of making multi-component quick assembly handle. 
     Yet another improvement is to provide a multi-component quick assembly handle which is postal friendly. 
     Yet another improvement is to provide a multi-component quick assembly handle which, once assembled, is close to being a permanent length handle. 
     Accordingly, the invention is directed to a multi-component quick assembly handle. The multi-component quick assembly handle includes a first tubular member made of a permanently deformable material having a first end permanently formed with a predetermined diameter and connecting to a second end forming a remaining portion of the first tubular member of a smaller diameter. There is also a second tubular member made of a permanently deformable material having a first end with a predetermined diameter substantially that of the first end of the first tubular member and connecting a second end forming a remaining portion of the second tubular member having a larger diameter and an inner diameter to complementary receive by way of a friction fit the second end of the first tubular member. At least one of the first ends having a connector for connecting a cleaning head, such as a mop or broom, to form a cleaning implement. Another embodiment employs intermediate tubular member(s) similarly formed for interconnection as described above. 
     A method of forming multi-component quick assembly handle, which includes the steps of providing a first tubular member and a second tubular member of a first predetermined inner diameter and a second predetermined outer diameter wherein the tubular members are made of a permanently deformable material, providing a female forming tool having a female forming end including a terminal portion of a smaller diameter than the first inner diameter and an inwardly extending section having a maximum outer diameter slightly larger than the first inner diameter, the section connecting to a remaining portion of the female forming tool and wherein the female forming end is inserted into an end of the second tubular member under pressure to permanently deform end of the second tubular member to be a female end. 
     Further, the method includes providing a male forming tool having a male forming end having an opening with an entry inner diameter larger than the second outer diameter of the tubular members and an inwardly disposed inner diameter approximately that of the maximum outer diameter of the female forming tool and wherein the male forming end receives under pressure an end of the first tubular member it permanently deforms an end of the first tubular member to have outer diameter deformed complementary to be friction fit received into the female end said second tubular member. The formed male end and female end 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 a cleaning head, such as a mop or broom, providing a cleaning head connector and connecting the same to one of the first ends to form a cleaning implement. 
     The assembled invention replaces the previously described handles providing for multiple fixed length handles, filling the same functions and using the same storage space. The present invention can only be put together one way, thus making it a one-way assembly. 
     The invention is postal friendly. For example, United Parcel Services charges a $9 surcharge for packages at 48″ or more in length. Many current cleaning tools are 48″ or longer. The invention eliminates this charge by fitting the handle into a much smaller box, without loss of function.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
     Referring now to the drawings, the embodiments of the multi-component quick assembly handle of the instant invention is generally designated by the numerals  10  and  10 ′ where like numbers refer to like parts. The multi-component quick assembly handle  10  and  10 ′ includes a first tubular member  12  and  12 ′ made of a permanently deformable material, such as aluminum or other extrudable metal material, for example. By “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 (x−Δa) 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+Δb) and an inner diameter (y) slightly larger than diameter (x−Δa) 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 or handle cap  29  with an eyelet for press-fit into either end  20  or  14  for permitting hanging and storage of the cleaning implement. 
     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 (z−Δd) smaller than the inner diameter (z) and a section  36  having a maximum outer diameter (z+Δe) 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. 
     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 (z−Δe′) larger than the outer diameter (x) of the tubular members  12 ,  50 , and  18  and an inwardly disposed inner diameter (z−Δd′) which is slightly smaller than diameter (z−Δd) 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. 
     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 (x−Δa). The second end  16 ′ includes one or more stamped inwardly extending crease  21 ′ to form one or more 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 diameter (x) and an inner diameter (z) which tapers to a smaller inner diameter (z−Δd) which are slightly larger than diameter (x−Δa) 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 ′. The tapered section  19 ′ is formed by tube pinching process whereby a press sandwiches about the end  22 ′ pinching sides of the same to form outwardly extending pinched portions  23 ′. 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 or handle cap  29  with an eyelet for press-fit into either end  20 ′ or  14 ′ for permitting hanging and storage of the cleaning implement.  FIG. 7  illustrates that the parts  18 ′ and  12 ′ can serve as top of bottom parts. 
     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 pinching tool (not shown) including a portion for receiving end  22 ′ and pinching opposing sides thereof thus providing of a diameter (z−Δd) smaller than the inner diameter (z). 
     Further, the method includes providing a male forming tool (not shown) having a crimping receiving end forming inwardly extending crease  21 ′ in end  16 ′ thereby providing a tapered surface. The ends  16 ′ and  22 ′ are permanently deformed.  FIG. 8  illustrates an additional interconnecting member  50 ′. It is understood that there can be multiple complementary formed members  12 ′,  18 ′,  50 ′. Member  50 ′ includes tapered sections  53 ′ and  55 ′ formed by crimp(s)  56 ′ and pinched portion(s)  57 ′. 
     The formed male end  16 / 16 ′ and female end  22 / 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. 
     By so providing, the instant invention, there is an advantage in that the tubular members enable the connection to become substantially permanent press-fit where they are put together only once. The interconnectable tubular members  12 ,  12 ′ and  18 ,  18 ′ members (optional  50  or like formed member) enable the shipment in a smaller box. The very popular Swiffer™ is an example of an existing cleaning implement which can be dis-assembled but rarely is 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. 
     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 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. 
     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. 
     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.
