Detangling hairbrush

Abstract

The Detangle hairbrush addresses the problem of removing the tangles from one's hair without pulling the hair loose from your scalp by moving the bristles in the same direction at the same time in a rapid back and forth motion the bristles will shake the strands of hair loose from the tangle instead of pulling them free from one's head as in the case of the fixed bristle hairbrush. The hairbrush handle consist of a cylinder or square shaped grip to accommodate the batteries, motor, gears, and pushrod that make up the drive system for the bristle plate. The head portion of the handle has C-shaped channels protruding downward from the long sides of the rectangular shaped head of the handle having the channels parallel and pointing toward the center creating rails for the bristle plate to ride on. The bristle plate is then slid into the rails of the handle and attached to the pushrod in such a manner as to allow the bristle plate to move freely along the rails rapidly in a back and forth almost, vibrating motion therefore shaking the tangle loose instead of pulling it, unlike fixed bristle hairbrushes of the past

BACKGROUND OF THE INVENTION

Everyone with long hair has had the unfortunate task of pulling out their hair while trying to comb out tangles. I designed the detangler hairbrush to address this problem. The detangler hairbrush has moving bristles that stroke in a back and forth motion driven by an electric motor. This rapid motion of the bristles while being pulled thru tangled hair will separate the strands of tangled hair therefore shaking the hair free from the tangle without pulling it out. Hairbrushes of today were designed to separate and shape hair. However hairbrushes of today have never addressed the problem of removing tangles without pulling the hair out of your head.

BRIEF SUMMARY OF THE INVENTION

This hairbrush consist of an elongated hallow cylinder shaped handle on one end having a rectangular shaped head on the other end; the head having a rectangular top with two 90 degree angle shapes protruding downward from the top of the head and running parallel with one another on each of the long sides of the head forming a guide for the bristle plate to ride on; The bristles or bristle plate is an arced rectangular shaped thin sheet of plastic or metal having separate rows of stiff bristles protruding downward from the sheet; having each row pointing in a different angle around the arc of the sheet; The bristle plate also incorporates a groove at the top of plate running parallel with each long edge of bristle plate these grooves will allow the bristle plate to attach to the head of the hairbrush by sliding into the angles or guides accommodating for the bristle plate to easily move back and forth; At either end of the bristle plate there is an end plate attached across the arc of the plate perpendicular to the grooves; A push rod is attached to one of the end plates and at the other end the rod is attached to a gear that is powered an electric motor in such a way that when the motor is running the bristles and bristle plate will move back and forth in the same direction at the same time in a to and from motion; On one end of the handle the top portion is removable to accommodate for dry cell or rechargeable batteries to operate the hairbrush. This invention solves the problem of taking tangles out of hair without pulling the hair out. In doing so it massages and stimulates the scalp, unlike hairbrushes of today which just pull the tangle out.

DETAILED DESCRIPTION OF THE INVENTION

This hairbrush is comprised of three major parts first being the lower handle. The lower handle portion of the hairbrush consist of a hollow rectangular portion at one end and a hollow elongated half cylinder shape portion forming into a rectangular shape on the opposite end; having metal contactors on the end of the hollow rectangular portion to supply current to the drive motor located in the half cylinder. The drive motor turns the gear which moves the pushrod therefore moving the bristle plate in a to and fro motion along the guides formed into the rectangular head portion of the lower handle; The end of the cylinder closest to the rectangular head portion of the lower handle extends out to the width of the head portion of the lower handle and is also hollow with affixed pins to accommodate for the motor, gears, and push rod which make up the drive assembly for the bristle plate. The head portion of the lower handle is a rectangular having a convex top having a ninety degree angles extending downward from both long sides of the rectangle with the lower sides of the angles pointing to the center of the rectangle creating a c shaped groove on each long side of the rectangular head portion of the handle acting as guides for the bristle plate to ride on. The upper handle portion of the brush has a hollow rectangular portion on one end leading into a hollow half cylinder shape which then widens out to the width of the head portion of the lower handle this allows the upper handle to fit snugly over the motor and battery. The upper handle is removable to allow for batteries to be inserted into the handle. The third part of the hairbrush is the bristle plate. The bristle plate is a sheet of material rectangular shaped around the perimeter; the sheet is bowed to form an arc across the short sides of the rectangular sheet; with both short ends of the sheet having plates permanently affixed to strengthen and hold the sheet in a permanent arc; the long sides of the sheet having c shaped channels affixed to the top pointing outward from the center and running parallel with each other down the long sides of the sheet with the dimensions being such that the channels create a guide allowing one to attach the bristle plate to the hairbrush lower handle. The bristle plate will have a plate affixed to the top of the channels flush around the parameter of the channels forming the bristle plate into one piece this plate having a hole drilled thru it centered at one end to accommodate for the push rod; the arced side of the bristle plate having straight rows of separate cylinder shaped bristles protruding outward from the plate at a ninety degree angle having each spaced equally around the arc of the plate. Upon assembling the bristle plate and the hairbrush lower handle one can insert batteries into the handle replace the upper handle and turn on; the drive system in the handle of the hairbrush will move the bristle plate in a rapid back and forth motion causing the bristles to move in the same direction at the same time creating a vibrating effect on the bristles therefore when the moving bristles are pulled through the hair it shakes the tangled strands of hair free from the tangle instead of pulling them free from the scalp thus encompassing the improvement over other hairbrushes and hair care appliances on the market today which just remove tangles by pulling them out.

Claims

1. “What I claim as my invention is: by moving the bristles rapidly back and forth in the same direction at the same time, the bristles of the brush shake the strands of hair loose from the tangle instead of pulling the hair from the scalp”.

2. “What I claim as my invention is: the back and forth motion of the bristles against the scalp massages and stimulates it creating a soothing effect on the user”.

3. “What I claim as my invention is: that this hairbrush can also be made rechargeable”.
