Definitions

  • This invention concerns the attachment of extensions to the hair of persons.
  • An aim of the present invention is to provide an attachment method and equipment to address such a need.
  • the invention provides a method of attaching supplemental hair to human natural hair, by using a hand tool comprising a pair of jaws with attached handles, a stop means, and a spring means urging the jaws apart, said method comprising: (a) threading a plurality of strands of said human hair through a plastically deformable tube, (b) inserting into the tube an end of a lock of said supplemental hair,
  • the hand tool preferably has a pliers-like construction including a first handle, a second handle, a first jaw and a second jaw.
  • the first handle may have a tubular portion within which is an adjustment screw which adjusts longitudinally to said first handle to set the extent of said flex before said stop means is engaged.
  • a handle-linking member is slidably engaged at a first of its ends with said first handle and pivotally engaged at the second of its ends with said second handle and a portion of said handle-linking member spaced from said handle-linking member's ends bears against said stop means thus preventing the handles being squeezed closer together.
  • the stop means is preferably a protrusion located within said second handle.
  • the first jaw and the first handle are fastened together in a fixed relationship
  • the second jaw pivots from the first handle on a first pin
  • the second handle pivots from the second jaw on a second pin
  • a handle-linking member is slidably engaged at a first of its ends with said first handle and pivots on a third pin through said second handle, said first end of the handle-linking member bears against said adjustment screw at a contact
  • the axis of said third pin is prevented by the stop means from passing through a straight line drawn between the axis of the second pin and said contact between the handle-linking member and the adjustment screw.
  • the invention provides a pliers-like hand tool for attaching supplemental hair to human natural hair, said hand tool comprising a pair of opposed jaws with attached handles for squeezing the jaws towards each other, a spring means urging the jaws apart, each said jaw having a smooth face opposing another smooth face on the other jaw and a smooth surfaced straight groove upon each of said opposed smooth faces, wherein when said jaws are closed said grooves in conjunction form a smooth-surfaced hole between the jaws.
  • said grooves have a semicircular cross-section such that when said jaws are closed said smooth-surfaced hole between the jaws is cylindrical.
  • the invention provides a method of attaching a lock of supplemental hair to human natural hair, and later detaching the lock of supplemental hair, comprising the steps of:
  • the lock of said supplemental hair preferably comprises a plurality of individual hairs bonded together at one end by a short cylindrical plug of hardened adhesive, said plug being a loose sliding fit in said tube.
  • the invention provides a method of attaching a lock of supplemental hair to human natural hair comprising the steps of:
  • the invention provides a method of detaching a lock of supplemental hair previously attached to a plurality of strands of human hair by clamping said lock and said strands of human hair together in a flattened plastically deformable tube which has a coloured coating on its outer surface, said method of detaching comprising the steps of:
  • each said jaw has formed therein a smooth surfaced straight groove having a semi-circular cross-section sized to be a snug fit on the tube before said flattening, and said flattened tube is positioned within said smooth grooves when squeezed to unflatten the tube, said tube thereby being reformed to a cylindrical shape without causing significant damage to said coating.
  • Figures 1 to 3 show successive steps in the process of attaching a lock of supplemental hair to some strands of human hair according to one embodiment of the invention
  • Figure 4 is a cross section view of a short tube shown in Figures 1 to 3;
  • Figure 5 is a side view of a hand tool used in the process
  • Figure 6 is a side view of the tool in Figure 5 shown with a tube squeezed between its jaws to the point where the human hair and supplemental hair are firmly held by the deformed tube;
  • Figure 7 is a view similar to Figure 6 but with the handles squeezed tighter together until a stop means is engaged;
  • Figure 8 is a partially cut-away view of the tool, shown with its adjusting screw adjusted excessively in one direction; and Figure 9 is a partially cut away view of the tool, shown with its adjusting screw adjusted excessively in the other direction.
  • a lock 10 of supplemental hair has been earlier prepared by bundling together an appropriate plurality of individual hairs 12 in a generally parallel configuration and bonding them together at one end by a short cylindrical plug 14 of appropriate glue.
  • a thermoplastic glue is suitable but other glues may be used.
  • the hair in the lock 10 may be around 50cm long, but any desired length may be used.
  • the hairs in the lock may be of synthetic material, but natural hairs are preferred. Such locks are commercially available.
  • strands 16 of a person's natural hair are separated and threaded through a short tube 18. This may be conveniently achieved (but not shown in the Figures) by first passing a loop of thread through the tube, passing the hair strands through the loop and then pulling the loop back through the tube, so pulling the hair strands 16 also through the tube.
  • the plug 14 is then inserted into the tube 18 so the lock 10 extends outwards in the same direction as the natural hairs 16.
  • the tube is then squeezed tight with a hand tool, which is described later in this specification, to flatten the tube so that the plug 14 and the hairs 16 are clamped within the tube.
  • the flattened tube 26 is shown in Figure 3.
  • one end 20 of the tube 18 is slightly flared out at its rim in order to make insertion of the plug 14 easier from that end.
  • the rim at the other end 22 of the tube 18 is rolled inwards a little, which assists in preventing the plug being pushed too far through the tube.
  • the tube 18 is preferably made of copper or brass, or perhaps aluminium, but could be another appropriately malleable metal alloy.
  • the outer surface 24 of the tube has paint or some other coating applied to it to give it a colour close to that of the hairs 12 in order to make the tube as inconspicuous as possible. For this reason, the manner in which the tube is squeezed is important so as to not damage the coating.
  • the tube is squeezed by means of the hand tool 30 shown in Figure 5.
  • the tool has the general form of a self locking pair of long nose pliers.
  • the present tool 30 uses a jaw movement and leverage principles similar to many locking pliers, it is specifically designed to have no self locking function.
  • the pliers 30 have an elongated handle member 32 which includes an elongated upper handle 34 and an upper jaw 36.
  • the upper handle is fixed in relationship to the upper jaw.
  • a lower jaw 38 pivots, on a pin 40, from the upper handle 34 and an elongated lower handle 42 pivots, on a pin 44, from the lower jaw 38.
  • the lower handle 42 has a forward end 62 adjacent the jaws 36 and 38 and a distal end 50 away from the jaws.
  • the upper handle 34 has a forward end 64 adjacent the jaws and a distal end 48 away from the jaws.
  • the lower handle 42 has a channel-shaped cross section, and its forward end 62 is bifurcated and a corner 43 of the lower jaw 38 is pivoted, between the bifurcation arms, on the pivot pin 44.
  • the forward end 64 of the upper handle is channel shaped and another corner 39 of the lower jaw is secured within the channel by the pivot pin 40.
  • the distal end 48 of the upper handle is cylindrically tubular and contains an adjustment screw 58 which is threadably engaged with a nut 60 which is rigidly attached to and within the upper handle 34.
  • the screw 58 has, at its distal end, a slotted head 59 which may be rotated for adjustment by a screwdriver inserted into the tubular end of the handle 34.
  • At the screw's other end 56 it has a flat end face 57 transverse to its axis.
  • a removable plastic cap 61 plugs the end 48 of the upper handle and restricts access to the head 59 of the adjustment screw once the screw is set as desired. The operation and adjustment of the screw is described later in this specification.
  • a handle-linking member 46 links the handles 34 and 42 in the region between the pivot pin 40 and the distal ends 48 and 50.
  • the handle-linking member is pivotally engaged at one of its ends (the lower end) 52 about a pivot pin 53 through the lower handle 42.
  • the other end (upper end) 54 is engaged with the upper handle, and in particular with the end face 57 of the adjustment screw 58.
  • An extension coil spring 66 extends between respective anchoring holes 68 and 70 in the upper handle and the lower jaw. The spring urges the jaws 36 and 38 apart and, by doing so, urges the pivot pins 44 and 53 rearwards and thus urges the upper end 54 of the linking member 46 into contact with the abutment end 56 of the screw.
  • a stop 72 is formed within the channel-shaped lower handle 42.
  • a bulge 74 on the linking member 46 hits the stop 72 when the desired maximum force is applied to the handles.
  • the pivot pin 53 cannot move over centre (ie the centre of pin 53 cannot cross a straight line drawn between the centre of pin 44 and the linking member's contact with the abutment 56).
  • the jaws 36 and 38 have respective opposed faces 76 and 78.
  • Each of faces 76 and 78 has a smoothly polished flat surface except for a smoothly-walled straight groove, 80 and 82 respectively, of semi-circular cross-section which runs across the width of each face 76 and 78 about half way along the face.
  • the flat portions 77 and 79 of faces 76 and 78 respectively are each bisected by their respective grooves 80 and 82.
  • Closing the pliers 30 by moving the handle 42 towards the handle 34 causes the pin 44 to move forwards and the flat surface portions 77 and 79 to shut flat against each other (as seen in Figure 9) when there is nothing between the jaws.
  • the grooves 80 and 82 are aligned relative to each other so that when the jaw faces 76 and 78 are in contact, the grooves in conjunction form a smooth-walled cylindrical hole 83 through the closed pliers 30.
  • a hard stop with tactile feedback means the operator knows that sufficient force has been applied to the tube, and also prevents possible cutting of the natural hair 16 from over compression of the tube. It also means that, even though an operator may be applying over 100 locks of hair over a short period, any tiredness does not result in a variation of the holding force applied by the tubes to the hair. Also, different operators will produce the same holding force within the tubes despite individual differences in the strength of the operators.
  • Figure 8 is included to show the effect of having the screw 58 adjusted out much too far. In this situation the bulge 74 has contacted the stop 72, so preventing further closure, before the jaws 36 and 38 have closed sufficiently.
  • Figure 9 illustrates the effect of having the screw 58 adjusted in much too far.
  • the bulge 74 fails to contact the stop 72 so, after sufficient compression has been applied to the tube, further increased squeezing of the handles mainly causes excessive flexing of the handles without a discernable further closing of the jaws 36 and 38.
  • the position as illustrated in Figure 9 is also extreme, it can be seen that closer to (but still short of) the desired setting, excessive force could be applied after the tube is sufficiently compressed thereby damaging the hair. Such a poor adjustment condition is sensed by a skilled operator as excessive flexing of the handles before the stop is engaged .
  • the faces 76 and 78 have generally parallel edges for most of their length, and their width is the same as or slightly greater than the length of the tubes 18.
  • the tubes are about 7mm long, 2.5mm internal diameter and 3mm external diameter. So the jaws are about 7mm wide at the groove.
  • the grooves 80 and 82 together form a cylindrical hole 83 of 3mm diameter across the jaws when the jaws are closed.
  • the flattened tube 26 is placed between the jaws, with its thin edges in the grooves 80 and 81, and the handles are squeezed by one hand of the operator.
  • the tube opens up and is formed by the grooves 80 and 81 into a near perfect cylindrical tube again.
  • the plug 14 and strands of natural hair 16 are then easily removed from the tube.
  • the tube may be reused if desired, an advantage made possible by the smooth surfaces 77 and 79 not damaging the coloured surface during flattening of the tube, plus the smooth surface and accurate sizing of the grooves 80 and 82 causing a full and accurate reforming of the tube. It has been found that tubes may be successfully reused more than ten times in this manner.
  • the handles 34 and 42 include wing portions 84 and 86 extending outwards in the plane of motion of the handles and towards the jaws.
  • the wing portions 84 and 86 are smoothly blended into the shape of the handles and assist in preventing the operator's hand from sliding forwards, thus improving operator comfort.

Abstract

L'invention concerne un procédé permettant de fixer des cheveux supplémentaires sur des cheveux naturels humains, en utilisant un outil manuel comportant une paire de mâchoires munies de branches attachées, un moyen de butée, et un ressort forçant les mâchoires à se séparer. Une pluralité de mèches desdits cheveux humains sont enfilées au travers d'un tube plastiquement déformable et une touffe de cheveux supplémentaires est insérée. Les branches sont serrées pour aplatir le tube entre les mâchoires pour de ce fait serrer la touffe et les mèches ensemble. Les branches sont alors comprimées pour se rapprocher l'une de l'autre, ceci amenant les branches et/ou les mâchoires à fléchir sans autre déformation significative du tube, jusqu'à l'enclenchement du moyen de butée pour empêcher les branches d'être comprimées pour se rapprocher encore plus l'une de l'autre. Le ressort ouvre les mâchoires, relâchant ainsi le tube déformé.
