Description

Heated bristle curling brush

This patent is a continuation of the application serial no 597950 of application on April 9th, 1984.

The present invention describes a kind of heated bristle brush, is used for decorative hairstyle and hair is tangled or the shouting pain scalp.In traditional technology,, numerous trials was arranged once for a kind of device of curling hair with the effective and easy scrubbing brush of brush of heating is provided.Solve in the prior art of the suitable brush winding apparatus of this class being devoted to, United States Patent (USP) 675527,1258375,1393635,1436957,4030158,4314137 and 4368376 is typically arranged.

These devices are divided into two classes: the first kind, only being used for brush combs one's hair, typically see United States Patent (USP) 675527,1258375,1393635 and 4030158, this class device is mainly used to comb along hair by the mode of directly smoothing out with the fingers, and with known air-blow drying machine logotype the time, provide a support that helps dry hair; Second class is the curly hair flatiron or the curling brush of heating, is used for decorative hairstyle and make it to be wave, and representational device is seen United States Patent (USP) 4314137 and 4368376.

Although the brush in first group generally can satisfy the usefulness that traditional brush is combed one's hair, they are not suitable for hair crimping or make it to roll out the wave flower.As for second group, when realizing making curly headed with them or playing the function of wave, the tendency that makes hair tangle in this curling brush or make the hair entanglement is arranged.Remove this, more than arbitrary class brush owing to adopted the common hard hair on the neck of pin type, this frame mode shouting pain in use or scratch scalp.

In addition, if adopted the metallic hard hair on the neck, the user will cause tenderness when touching this warmed-up hard hair on the neck, especially begin to be wound on the curler when hair, and the user holds the end of hair in order to avoid its slippage when opening this curling brush is all the more so.

Another problem that the brush that uses conventional art to make causes is to tangle owing to reversing of brush makes hair when the coiling topknot.By the bristle curling brush that prior art is designed to, be everlasting hair after several circles of this brush, because rigid needle or hard hair on the neck are seized the below hair, usually cause and tangle.The general version of this class brush is on the supporting mass of handle front end, a collection of metal needle or plastic teeth to be housed.The hair entanglement problems all can take place in the brush that is metal needle or plastic teeth type.But, the plastic teeth of some traditional brush can not make the above hair of one deck arrive in tooth slightly under, thereby the entanglement problems in this type of brush is not too serious.On the other hand, in the brush that the metallic hard hair on the neck is arranged, the shape of the hard hair on the neck of this kind, flexibility and coefficient of friction, make have the hair of multilayer slide to this hair on the neck slightly under, have now found that this can cause hair seriously to tangle.

Brush the device of comb or hair crimping except there being an above-mentioned class to be used to, the another kind of device that is commonly used to perm is still arranged.The latter generally is called curler or around sending out device, is the cylindrical member of some external heat, after the preheating of auxiliary coiling effect, and several layers of hair in the winding.Typical this class device is seen United States Patent (USP) 3566887 and 3706315.Though this type of device be suitable for curly hair, but and be unsuitable for the brush comb one's hair.Also to point out, because their design form,, limit them and generally can only reel last one or two-layer hair by the effect of shred on the curler or scuppit.

The size of warmed-up hard hair on the neck spare and space thereof should be able to prevent that preferably user's finger from touching above-mentioned columnar member.The user generally is not intended to touch this columnar member.On the contrary, when they begin revolving brush, be the top that finger is placed on the hair end, in order to avoid taking place slippage.Put finger in such a way, the user will touch hard hair on the neck.For the hard hair on the neck of plastics matter, because they are colder and can not quick conductive, this can not cause great problem.But the hard hair on the neck that just has a conductive structure in fact, and contacting with hard hair on the neck on the contiguous guard shield that has heated will scalded skin.This problem is resolved after adopting the present invention basically, and it allows the user for when brush rotates and the desirability that must hold the hair end is reduced to minimum.Catch the hair can be by a kind of surface with many nicks portion is provided when brush begins to rotate, that is, the columnar member with a kind of roughening face, waddingization face or rubber face be realized.

The present invention heats hard hair on the neck used in the curling brush, and its end that touches scalp should be quite smooth, in order to avoid shouting pain scalp in use.The heatpiston thin with one deck applies this end, owing to slightly reduced terminal temperature, can also improve comfort and degree of safety.

Also do not disclosed the bristle curling brush that adopts such class in known systems: its employed hard hair on the neck, the possibility that causes hair to tangle is quite little, and can be heated to and make heat throughout in each layer topknot.In addition, in those known heated bristle curling brush, for example United States Patent (USP) 4314137, and such class belongs to one type of prior art syringe, all do not hinted to remove to heat hard hair on the neck ring-type or arc how effectively.Have found that, adopt the hard hair on the neck of arc, make its each end and the fuse of a heating do thermo-contact, just can be under the fuse condition of application of cold temperature heating, the end that makes above-mentioned hard hair on the neck more can reach satisfied operating temperature than adopting the straight hard hair on the neck of point pin type." arc " speech that this specification is generally quoted is interpreted as getting the hard hair on the neck form that differs from real arc.This type of hard hair on the neck can be solid or hollow object of star, circle roughly or rectangle or the like.Unique requirement be that the bottom of each hard hair on the neck will be corresponding to greater than about 20 ° arc length on columnar member.

The present invention relates to a kind of like this heated bristle curling brush, comprise that a handle, one are from the extended columnar member of handle, this columnar member inside is provided with heating element heater, the peripheral surface that also has a longitudinal axis and be radially spaced with this longitudinal axis, have a collection of on this outer surface outwardly by angle branch, the hard hair on the neck of arc that longitudinally separates and extend radially, the bottom of each hard hair on the neck on the circumference of columnar member, occupy about 20 ° to about 110 ° arc length, the height of hard hair on the neck is at least half of columnar member diameter, but must not be lower than about 0.375 inch.The diameter of columnar member should be elected 0.375 inch to 2.0 inches as, but is more preferably 0.5 inch to 1.0 inches, and hard hair on the neck height at this moment is at least the post footpath partly, but is not less than about 0.375 inch.Two adjacent parallel hard hairs on the neck distance in the ranks along columnar member vertically separates will be enough to make brush to move in hair, being advisable between about 0.125 inch to 0.75 inch, but is more preferably about 0.25 inch.

The particular structure form of the hard hair on the neck that adopts in the brush of the present invention can not cause tangling of hair.Its reason is to have noticed contingent hair entanglement form.The hard hair on the neck of the sort of small-sized staight needle formula one class can insert a branch of hair that has tangled, and hard hair on the neck of the present invention then makes the hair of entanglement fall a side of another hard hair on the neck.The another kind of mode that can tangle is because the distortion of brush when the coiling topknot.If topknot is tightened on the columnar member, changing angle is can not cause entanglement, but when some hair when lax and hair has coiled than remaining, the distortion of columnar member can make it the confusion entanglement.This hair that is not under the tensioned state can be staggered in during coiling between the hard hair on the neck of needle-like.Even when these hairs have strained and have made it to be tiled on the columnar member, the above-mentioned hair that interlocks under also difficult the removing, this is to be interleaved to brush pin hair on every side from the disengagement down of the sort of state at random because almost can't make.

Why curling brush of the present invention does not make hair tangle, and is that it has unique hard hair on the neck configuration to require to enter the passage of below hair and is same passage from the passage that withdraws from, and no longer is wound on the hard hair on the neck hair therebetween.Such profile also can make hair under slippage on the hair on the neck tip, is convenient to heat better all around each layer hair to this brush.

Various instantiation of the present invention has been avoided above-mentioned hair entanglement problems.Utilize height at least about half inch, and bottom line is about 20 ° of each hard hairs on the neck to about 110 ° of a part of arc length on the columnar member circumference, around to brush or, can make it very fast staggered around to a hard hair on the neck and during tension at hair.Also may make hair from the capable top-cross mistake of hard hair on the neck, can not take place but the next phenomenon of rollback is arranged then in such hair winding last three again again, this is because the hard hair on the neck of annular as the tooth of comb, separates them when entering the hair clump.The hard unnecessary symmetrical configurations of getting of hair on the neck also can realize the desirable result of the present invention.

When if selected instantiation has adopted the arcuation configuration of the metallic hard hair on the neck with semicircle end, the spacing of hard hair on the neck to make it along occupy on the columnar member circumference about 20 ° to about 50 ° arc length, the row of these hard hairs on the neck vertically separates about 0.25 inch interval along column piece, in order to avoid user's finger can insert between these hard hairs on the neck, prevent that it from contacting with warmed-up columnar member periphery in the brush.

In a preferred instantiation, hard hair on the neck is the arcuate member that is made of metal, and each end of each hard hair on the neck bottom is all done thermally coupled with columnar member.The two ends of hard hair on the neck contact with the inner core body of column, make it the heater heating by core body inside.Hard hair on the neck radially stretches out from the line of rabbet joint of the guard shield that covers this inner core body or cover.Though can heat by device general positive temperature coefficient or resistance heated, generally acknowledge and to adopt other heat forms, as butane catalytic heater or forced air etc.

Hard hair on the neck of the present invention can make heat reach the contiguous hair that hard therewith hair on the neck contacts from the columnar member of hotter (120 ℃ to 150 ℃), and the temperature with hard hair on the neck tip remains to about 40 ℃ to 70 ℃ simultaneously, preferably should remain to 60 ℃ to 70 ℃.Structure of the present invention can improve the thermo-contact between the inside core body of hard hair on the neck and heating, and makes heat effectively reach the end of hard hair on the neck from core body.
