Description

The invention to which this application relates is a threading apparatus.
Although the following description refers to a children's toy in the form of a thread-wrapping machine and a means for colouring threaded material, the person skilled in the art will appreciate that the present invention could also be used for other threading and/or winding purposes.
Children's toys enabling the user to thread and/or lace a plurality of articles together to form bracelets/anklets/ necklaces and/or the like have been known for some time. They can be provided in various forms, for example, some are provided with a single piece of thread, lace etc. on which charms and other decorative articles are threaded, creating a custom necklace, bracelet or anklet. Alternatively, a user may wish to create a customized bracelet, often termed a "friendship bracelet". This may involve intertwining a number of different threads about each other in order to create a more intricate design. Charms and other decorative articles may be added again in order to further customize the bracelet. Often, the children constructing jewellery items such as these will do so with their hands, and the process can be quite time consuming. German patent application DE4427687 (A1 ) discloses an apparatus provided to wrap optical fibre from a large supply spool to a smaller spool, while also providing means by which to colour the fibre as required.
US3808618 (A ) provides a method of continuously dyeing a yarn. The method involves heating a running yarn to a temperature above the boiling point of a solvent in a dye and contacting the heated yarn with one or more dye applicators having a dye discharge aperture while discharging a dye through the aperture and onto the yarn.
Japanese patent application JPH11106133 (A ) sets out to provide a winding thread package capable of attaching a thread end on to a surface conveniently and securely. An end of thread is provided and which is subsequently coloured and forms a winding thread package.

Referring firstly to Figures 1-3, there is provided an apparatus in the form of a thread-wrapping machine (1) provided to enable thread from a number of spools (3) to be simultaneously wrapped about an article (5). The thread-wrapping machine (1) includes a housing (7) in which there is located a rotating member in the form of a disc (9). In this embodiment the disc (9) has a number of holding members in the form of spool holding bars (11) protruding outwardly therefrom, on which the spools (3) may be placed. Although the present example illustrates three holding bars (11) on the disc (9), the skilled person will appreciate that this number may vary depending on the specifications of the thread wrapping machine. Rotation of the disc (9) is activated by switch (13) located on the housing (7) of the apparatus (1). The housing (7) of the apparatus (1) is located on a base (15) and is movable therealong relative to a supporting portion (17), located at an end (19) of the base (15), which is fixed in position on the base (15). A support bar (21) is provided on the supporting portion (17), protruding outwardly therefrom toward the housing (7). A central hole (23) is formed in the rotating disc (9) and extends through the housing (7) of the apparatus (1). The hole (23) is located substantially in line with the support bar (21).
A first end (25) of the article (5) about which thread is to be wrapped is attached to the support bar (21). The article (5) has a maximum radius sized to fit through the hole (23) in the housing (7) and once located on the support bar (21), a second end (27) of the article (5) extends through the hole (23), allowing the housing (7) to move back and forth along the base (15) with the article (5) sliding through the hole (23). With the spools (3) located on their respective holding bars (11), the ends of each strand of thread are taken and attached to the first end (25) of the article (5), with the housing (7) located in close proximity to the supporting portion (17) initially. Once the thread ends are attached to the article (5), the switch (13) is activated, causing the disc (9), and consequently the holding bars (11) and spools (3), to rotate about the article (5). During rotation, thread is unwound from the spools (3) forming a layer of multiple strands of thread simultaneously wrapped about the article (5). As the article (5) is wrapped with thread, the housing (7) is moved gradually away from the supporting portion (17) along the base, thereby exposing more of the article (5) to be wrapped. The spools (3) of thread may be provided in various colours, resulting in a varying range of colours and/or patterns of thread wrapped about the article (5). Once the article (5) has been wrapped / covered in thread to a sufficient degree or to a user's satisfaction, rotation of the disc (9) is ceased via the switch (13), the housing (7) moved to a distal end (29) of the base away from the supporting portion (17), thereby allowing the article (5), now wrapped in multiple strands of thread, to be removed from the support bar (21).
The article (5) may subsequently be used as an item of novelty / children's jewellery, or as an accessory / attachment to an item of children's jewellery.
While the housing (7) of the thread-wrapping machine (1) is movable along the base portion (15) with respect to the supporting portion (17), it may also be detachably attached thereto, allowing a user to remove the housing (7) for maintenance, repair, or even use without the need for the base or supporting portions (15, 17).
Figure 4 illustrates an alternative embodiment of the thread-wrapping machine (401), which includes a protective cover (431) located thereon. The cover (431) encases the holding bars (411) and, hence, the spools (403) thereby preventing any fast-moving parts from becoming detached from the apparatus while moving and causing injury to a user. In order for an article to be wrapped when the apparatus (401) is presented in this form, the cover (431) includes a hole (433) located in its face opposite the central hole (423) of the housing (407). In this embodiment, a user holds the article (not shown) as it passes through the holes (433, 423) and is wrapped in thread. The cover (431) is also provided as a transparent body, enabling the user to view the progress of the thread-wrapping action.
Referring now to Figures 5-9, there is provided the housing (7) of the thread-wrapping machine (1) depicted in Figures 1-3. However, in this particular embodiment, the main body has been detached from the base portion (15). Guide means (535) are affixed to the rotating disc (9), each of which is associated with a corresponding holding bar (11), and located radially between each holding bar (11) and the central hole (23). Each guide means (535) has a guide hole (537) through which thread from each pool (3) is fed. Such a feature allows the individual thread strands to be combined and, upon rotation of the disc (9), intertwined, thereby creating a composite thread made from two, three or potentially more individual strands of thread.
An alternative supporting portion (517) is provided, which includes two faces. On the first face (539) there is located a plate (541), which is rotatable with respect to the supporting portion (517). The plate (541) can be attached to the holding bars (11) of the housing (7) or spools (3) located thereon. Such an attachment provides a connection between the supporting portion (517) and the housing (7) of the apparatus (1), such that upon rotation of the disc (9), the plate (541) is caused to rotate at the same angular velocity. The plate (541) includes a hole (543) located centrally thereon and in line with the hole (23) of the rotating disc (9) and a further hole (545) located on the supporting portion (517) extending through its first face to a second, opposing face (547). The holes (543, 545) are sized to allow strands of thread to pass therethrough. An alternative article (505) is located on the second face (547) of the supporting portion (517). The article (505) may be detachably attached to the supporting portion and, while attached, is rotatable with respect to the sporting portion (517). Rotation of the article (505) is actuated by rotation of the disc (9) and, consequently, the plate (541). However, the article (505) is arranged to rotate at a slower angular velocity than that of the disc (9) and the plate (541). Additional guide means (549) is provided on the second face (547) of the supporting portion (517) having a guide hole (551) located therein. The guide means (549) allows thread, which has been fed through guide holes (537) and subsequently holes (543, 545) in the plate (541) and supporting portion (517), to be fed through its guide hole (551) and finally attached to a first end (525) of the article (505). As the switch (13) is activated and the disc (9) rotates, the strands of thread from each spool (3) begin to intertwine with one another and are slowly fed onto and wrap around the article (505), creating a composite thread formed from multiple individual strands of thread. In theory, if several lengths of composite thread are formed, these can be put through the same process as the spools (3) of individual thread, thereby creating a secondary composite thread, and so on. Once wrapping of the thread about the article (505) is complete, the composite thread may be removed and used as an item of children's jewellery, such as a necklace, bracelet, friendship bracelet, anklet and/or the like.
Additionally, dying apparatus such as a marker (not shown) may be affixed to the apparatus and arranged so as to colour and/or recolour one or more of the strands of thread as they unwind from their respective spools. This feature may be added to alter the colour of a particular thread prior to it being intertwined with other thread strands and/or being wrapped about the article. For example, a user may affix a spool of white thread and wish to colour it prior to wrapping. This can be achieved by the provision of an appropriately coloured marker located in position on the apparatus. Several locations for markers may be provided so a user can, if they choose, colour each spool of thread that is place on the holding bars of the thread-wrapping machine.
Referring now to Figure 10, an exemplary apparatus for colouring a threaded material is depicted, and is generally referred to as apparatus 1000. Apparatus 1000 is but one example of a suitable apparatus, and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention. Neither should apparatus 1000 be interpreted as having any dependency or requirement relating to any single component or combination of components illustrated therein.
In one embodiment, apparatus 1000 includes a housing 1010 that includes or encloses a rotatable member (not shown), and which includes a drive (not shown) that rotates the rotatable member. The drive may be powered, such as by electricity, a windup mechanism, and so forth, or may be manually driven such as by a knob, crank, or lever, among others. Apparatus 1000 also includes a holding member 1012 that protrudes from the rotatable member, which is configured to receive a take-up spool 1014. In an embodiment, holding member 1012 includes a longitudinal shaft having a cross section that matches a cross section of a hole in the centre of take-up spool 1014, such that the spool rotates with holding member 1012. In another embodiment, holding member 1012 utilizes a gripping portion (not shown) that removably engages an end of take-up spool 1014. Non-limiting examples of the gripping portion include a circular recess, prongs, jaws, magnetic couplings, and so forth.
Apparatus 1000 also includes a primary thread guide 1016 that includes a passage 1018 through which the threaded material (not shown) is drawn as the threaded material is wound onto take-up spool 1014, and which directs the threaded material toward take-up spool 1014, according to one embodiment of the invention. Primary thread guide 1016 also includes a receptacle 1020 that is configured to receive and hold a colorant applicator or marker, such as a felt-tipped marker. Passage 1018 is positioned such that the threaded material is held against the marking portion (e.g., the tip) of the inserted marker as the threaded material is drawn through passage 1018. In the exemplary embodiment of Figure 10, primary thread guide 1016 is mounted on a primary guide support member 1022. In an embodiment, primary guide support member 1022 includes a shaft 1038 on which primary thread guide 1016 is movably mounted, such that primary thread guide 1016 is slidable back and forth along the shaft 1038 of primary guide support member 1022. The movement of primary thread guide 1016 causes the threaded material to be directed to different portions along take-up spool 1014. For example, moving primary thread guide 1016 back and forth causes the threaded material to be wound more evenly on take-up spool 1014. Primary thread guide 1016 may also be affixed to a movable member of primary guide support member 1022, such that the movable member enables primary thread guide 1016 to be moved.
Apparatus 1000 also includes a pay-out support member 1024 configured to rotatably support a pay-out spool (not shown) that holds the threaded material to be coloured. In an embodiment, pay-out support member 1024 includes a fixed shaft on which the pay-out spool rotates freely. In another embodiment, the shaft of pay-out support member 1024 may be rotatable, such that the shaft and pay-out spool rotate together. In another embodiment, pay-out support member 1024 utilizes a rotatable gripping portion that removably engages an end of the pay-out spool. Examples of a gripping portion include, but are not limited to, a circular recess, prongs, jaws, magnetic couplings, and so forth. Apparatus 1000 also includes a pay-out thread guide 1026 configured to guide the threaded material toward primary thread guide 1016 as the threaded material is unwound from the pay-out spool.
Apparatus 1000 also includes a cover 1028 attached to the housing, which at least partially encases or covers holding member 1012, primary guide support member 1022, primary thread guide 1016, pay-out support member 1024, and/or pay-out thread guide 1026. Cover 1028 is generally positioned between a user and the moving components of apparatus 1000 and serves as a protective shield. Cover 1028 may be at least partially transparent. A portion of cover 1028 forms an aperture 1030 positioned above primary thread guide 1016 such that a marker (not shown) may pass through aperture 1030 when inserted into receptacle 1020 of primary thread guide 1016. In an embodiment, the dimensions of aperture 1030 are such that the perimeter of aperture 1030 does not interfere with movement of the marker, which moves with primary thread guide 1016. In an embodiment, the dimensions of aperture 1030 are such that the perimeter of aperture 1030 limits movement of the marker and primary thread guide 1016 within a range that corresponds to the central winding portion of take-up spool 1014. This ensures that primary thread guide 1016 cannot be moved far enough in either direction to guide the threaded material off the end of take-up spool 1014. In an embodiment, movement of primary thread guide 1016 corresponds to manual movement of the marker by the user holding the marker, including moving the marker back and forth as the thread is wound onto take-up spool 1014. In an embodiment, the movement of primary thread guide 1016 is automatic. In another embodiment, a portion 1032 of primary thread guide 1016 extends beyond cover 1028 and may be used as a handle by the user to move primary thread guide 1016 with respect to primary guide support member 1022. As depicted in FIG. 10, portion 1032 of primary thread guide 1016 extends beneath a lower edge 1034 of cover 1028 and includes a notch 1036 that engages the lower edge 1034 of cover 1028.
Referring now to Figure 11, an enlarged portion of an embodiment of apparatus 1000 is depicted and is generally referred to as apparatus portion 1100. Apparatus portion 1100 is but one example of a suitable portion of apparatus 1000, and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention.

As described above with regard to Figure 10, passage 1018 is positioned such that thread 1120 is held against the marking portion (e.g., the tip and/or nib) of marker 1130. In an embodiment, as take-up spool 1014 rotates in a clockwise direction with respect to a central axis of the holding member 1012, thread 1120 is unwound from pay-out spool 1110 in a clockwise direction with respect to a central axis of pay-out support member 1024, is drawn through passage 1018 in primary thread guide 1016, and is wound onto take-up spool 1014. Additionally, based on positioning of a marker 1130 within the receptacle 1020, thread 1120 is drawn through passage 1018 and colorant from the marking portion of marker 1130 is deposited onto the thread. For example, a saturated nib of the marker 1130 may contact and/or engage at least a portion of the thread 1120 passing through passage 1018, to provide a coloured thread 1122.
In an embodiment, apparatus portion 1100 does not include housing 1010 described above with regard to Figure 10. Instead, the components of apparatus portion 1100 may be coupled to at least a portion of housing 7 that is usable with an embodiment of the thread wrapping machine as illustrated in Figures. 1-9 and discussed in detail in the Applicant's co-pending British patent application no. 1412502.5 . In an embodiment, disc 9 and the attached fixtures are removable from housing 7, and apparatus portion 1100 is configured to be removably affixed to housing 7 in place of disc 9. The rotatable member (described above with regard to Figure 10) and/or holding member 1012 may then be rotated directly or indirectly by a drive within housing 7. In an embodiment, a portion of housing 7 adjacent to disc 9 is removable, such that the portion of housing 7 and disc 9 are removed together, and the partial housing affixed to apparatus portion 1100 is configured to removably attach to housing 7 in place of the removed portion of housing 7.
Referring now to Figure 12, a cross-sectional view of an embodiment of primary thread guide 1016 is depicted, and is generally referred to as cross-sectional view 1200. Primary thread guide 1016 is but one example of a suitable primary thread guide, and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention. Neither should primary thread guide 1016 be interpreted as having any dependency or requirement relating to any single component or combination of components illustrated therein.
As described above with regard to Figure 10, in an embodiment primary thread guide 1016 is mounted on a primary guide support member 1022 which includes a shaft 1038 on which primary thread guide 1016 is movably mounted, such that primary thread guide 1016 is slidable back and forth along a longitudinal axis of the shaft 1038 of primary guide support member 1022. In an embodiment, the shaft 1038 of primary guide support member 1022 has a cross-sectional shape that matches a cross-sectional shape of an opening 1124 in primary thread guide 1016, such that primary thread guide 1016 is maintained in an upright position, or in a non-rotating position, as primary thread guide 1016 slides along an axis of primary guide support member 1022. In an embodiment, the cross section of primary guide support member 1022 approximates a "plus sign" as depicted in Figure 12. As such, the external surface of the primary support guide 1022 may correspond to an internal surface of the opening 1124 in the primary thread guide 1016, which restricts rotation of the primary thread guide 1016 and maintains alignment between the thread 1120 and the receptacle 1020. The cross-section of primary guide support member 1022 may also have other shapes corresponding to an internal surface of the opening 1124.
Cross-sectional view 1200 also depicts marker 1130 that is inserted into receptacle 1020, contacting at least a portion of thread 1120 to provide coloured thread 1122. As depicted, thread 1024 passes through passage 1018 and is disposed against a marking portion 1210 of marker 1130. Marker 1130 and/or marking portion 1210 may be any portion of a marking device configured to deliver a colouring solution and/or apply a colour to the thread 1120, such as a broad line Crayola® marker from Easton, PA. In one aspect, a colouring solution within a marker reservoir is directed onto the thread 1120 based on contacting the marker nib 1210. Examples of a colouring solution include a fabric marker solution, a permanent marker solution, ink, dye, and so forth. As thread 1024 is drawn through passage 1018 it is coloured by marking portion 1210 to provide coloured thread 1122.
Referring now to Figure 13, an exemplary embodiment of apparatus 1000 is depicted with pay-out spool 1110, thread 1120, and marker 1130. The depicted embodiment is but one example of a suitable apparatus, and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention. Neither should the depicted embodiment be interpreted as having any dependency or requirement relating to any single component or combination of components illustrated therein.
As depicted, primary thread guide 1016 is located near the distal end of primary guide support member 1022. As take-up spool 1014 rotates, thread 1120 is unwound from pay-out spool 1110, passes around pay-out thread guide 1026, and is drawn through passage 1018 in primary thread guide 1016, where it is coloured by marker 1130. The resultant coloured thread 1122 is wound onto the distal end of take-up spool 1014, corresponding to the position of primary thread guide 1016 along the central axis of the primary guide support member 1022.
Referring now to Figure 14, an embodiment of apparatus 1000 is depicted with pay-out spool 1110, thread 1120, and marker 1130. As described above, thread 1120 is coloured by marker 1130 as it is drawn through passage 1018 in primary thread guide 1016. Figure 14 depicts primary thread guide 1016 as moved to the proximal end of primary guide support member 1022 during the winding of coloured thread 1122 onto take-up spool 1014. Accordingly, the movement of primary thread guide 1016 causes coloured thread 1122 to be wound evenly along take-up spool 1014. In an embodiment, primary thread guide 1016 is moved manually, while take-up spool 1014 is mechanically or automatically rotated during colouring.
