1. Field of the Invention
The present invention relates to the field of mops and more particularly, to the field of deck mops. More particularly, the present invention relates to the field of manufacturing and assembly of deck mops.
2. Description of the Prior Art
In general, deck mops are well known in the prior art. One major component of a deck mop is the mop yarn which is attached to a mechanism through which the mop yarn is attached to a handle.
In general, the mop yarn is sewn together and thereafter is fastened to a handle by means of having a wire wrapped around the upper portion of the yarn so that it is fastened to the handle which is in simple terms a cylindrical stick made of wood or plastic. Alternatively, the mop yarn is sewn together and then retained by a plastic cup by which the yarn is attached to the handle.
The various apparatus for retaining the mop yarn together and attaching the mop yarn to the handle as known in the prior art involves a time consuming, labor intensive, inefficient manufacturing and assembly process. There is a significant need for a new and improved apparatus for assembling yarn for a deck mop and connecting the yarn to the handle.
The present invention is a novel, new and improved attachment collar for a deck mop, by which mop yarn can be quickly and efficiently attached together and by which the collar can be quickly and efficiently attached to a handle.
It has been discovered, according to the present invention, that if a collar is molded out of two separate half hemisphere sections connected by a strap, then mop yarn can be laid across the strap section and the half hemispheres brought together and sealed so that the upper middle portion of the yarn is entrapped within the fully formed hemisphere. Thereafter, the hemisphere serves as a collar to retain the mop yarn in fully operational condition.
It has further been discovered, according to the present invention, that if a half sleeve is molded into the top portion of each half hemisphere, with threads molded into the semi-cylindrical interior of each half sleeve, then when the half hemispheres are brought together to retain the mop yarn, the half sleeves are also brought together to form an integrated fully formed sleeve with a cylindrical interior and internal threads through which a handle is attached to the collar.
It has also been discovered, according to the present invention, that if mating fastener means are formed into the half sleeves, then upon being brought together, the half sleeves serve to retain the collar together.
It has additionally been discovered, according to the present invention, that after the half sleeves are brought together and retain the half hemispheres into a fully formed hemisphere, the half hemispheres can also be permanently affixed together to the full hemisphere by means such as sonic welding.
It has additionally been discovered, according to the present invention, that if fastener pins are molded into the interior of the collar such as within the half hemispheres and/or along the connecting strap, then upon formation of the fully formed hemisphere, the fastener pins further serve to securely retain the mop yarn within the fully formed collar and further interlock to retain the fully formed collar in a more secured formed position.
It has further been discovered, according to the present invention, that if a nipple is molded into the interior cylindrical wall of the sleeve and molded into the location of the interior cylindrical wall above the internal threads, then when the threaded end of the handle is screwed into the threads of the sleeve, and if a ratchet section with ratchet teeth are molded into the end of the handle at the location immediately above the threads, then the ratchet teeth will interlock with the molded nipple in the cylindrical wall of the sleeve so that the handle remains in the cylindrical wall of the sleeve of the collar and will not unscrew during use of the mop.
It is therefore an object of the present invention to create a new and improved collar wherein mop yarn which is located on a spool can be quickly unwound from the spool and cut to the appropriate length and laid within the collar and by which the collar can be quickly assembled together to retain the mop yarn therein in a quick and efficient manner.
It is a further object of the present invention to create a new and improved collar which has molded into it a sleeve with a cylindrical interior and having internal threads and a nipple member which can accommodate a threaded end of a mop handle and retain the handle in a manner so that it will not become unscrewed when the mop is in use.
It is a further object of the present invention to create means by which the halves of the collar which entrap the mop yarn can be quickly attached together and fastened together in a quick assembly process.
It is a further object of the present invention to provide further means within the collar by which the mop yarn of the mop can be secured and by which the collar can be further interlocked by the means which serve to secure the mop yarn.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
Referring to
When the halves of the collar are brought together to form a full hemisphere, a full sleeve is also formed from the two halves 22 and 32 and full internal cylinder having full internal threads are formed from the two semi-cylindrical walls 23 and 29 and two half thread sections 24 and 34. Fastener means are used to retain the half sections of the sleeve together. By way of example, male teeth 26 can be molded into one-half of the interior wall 25 of first half sleeve 22 and female receiving members 28 can be molded into the opposite interior wall 27 of first half sleeve 22. Similarly, male teeth 36 can be molded into one-half of the interior wall 35 of second half sleeve 22 and female receiving members 38 can be molded into the opposite interior wall 37 of second half sleeve 32. As illustrated in
Alternatively, as illustrated in
In one alternative embodiment illustrated in
In another alternative embodiment illustrated in
The strands of mop yarn are wound on a large spool and therefore, during the assembly process, the mop yarn 90 is unwound from a spool and cut to the desired length. The open collar 10 is positioned to be aligned with the spool of mop yarn so that the appropriately cut length of mop yarn is laid over the interior face 70 of attachment strap 40 as illustrated in
After the mop yarn 90 is laid across the attachment strap 40, the two half hemispheres 20 and 30 and the two half cylindrical sleeves 22 and 32 are brought together and attached together in the manner previously described so that the center portion 92 of the mop yarn 90 is trapped within the fully formed hemisphere 16 created by the two half hemispheres 20 and 30. The center 92 of the strand of mop yarn 90 then lies over the attachment strap 40 and the mop yarn 90 evenly hangs down from the hemisphere 16 as illustrated in
If fastener pins 52 and 62 are used, the fastener pins 52 and 62 are embedded into the strands of mop yarn 90 to trap the mop yarn within the fully formed hemisphere 16 and to further secure the mop yarn 90 into the hemisphere 16. If fastener pins 72 are used, the fastener pins 72 are embedded into the strands of mop yarn 90 to trap the mop yarn within the fully formed hemisphere 16 and to further secure the mop yarn 90 into the hemisphere 16.
As illustrated in
An additional innovation is the molding of a nipple 86 into the upper interior wall 88 of the fully formed sleeve 82 above the location of the fully formed threads 84. The mop handle 120 has a lower portion 110 having exterior threads 100 which are designed to be accommodated by and threaded into the fully formed threads 84 of fully formed sleeve 82. Immediately above threads 100 is a ratchet section 130 having ratchet teeth 140, which ratchet section and teeth surround the mop handle 120. After the mop handle threads 100 are fully threaded into the sleeve teeth 84, the handle 120 is further rotated until the nipple 86 interlocks with the ratchet teeth 140 as illustrated in
The entire collar assembly including all of the components mentioned above as part of the collar can be molded in one single operation and can be molded out of plastic, or any conventional synthetic material such as polyethylene, polypropylene etc. Although not preferred, it is also possible to make the collar out of metal.
