mv ROY P WOODRUFF ATTORNEYS SCALP MASSAGER This invention relates to a hand-held unit for applying a massage to the scalp.

Units for applying massages to the body are known. Typically, these units are adapted to be hand-held at one portion and rubbed over the body at another portion so as to apply a massage. Such units typically use spaced and protruding elements for contacting the body under pressure to apply a massage.

The massage applying elements of units heretofore used have typically been closely spaced and formed with their arcuate contour generated about a small radius of curvature. Such massage applying surfaces, as closely spaced on the unit have the disadvantage of being difficult to handle; these units rock in the hand when a massage is applied and applied uneven pressure to the body. Further, the arcuate contour generated about small radii of curvature of such massage units contacts the body at relatively small areas, producing a concentrated traumatic pressure rather than massaging force over a larger area. I l I An object of this invention is to provide a scalp massaging unit which is stabilized within the hand so as to be easily held and capable of applying uniform pressure to the scalp.

A further object of this invention is to provide relatively large contact surfaces for producing a comforting massage of the scalp.

An advantageof this invention is that the massage unit has a triangular shaped body which readily fits within the palm of the user. j

A further advantage of this invention is that the unit contains no moving parts or surfaces which can become entangled with the human hair when a scalp massage is applied.

Other objects, features and advantages of the present invention will be more apparent-after referring tothe following specification and attached drawings in which:

FIG. 1 is a plan view showing a triangular shaped unit body with the protruding massage pads located at the body corners;

FIG. 2 is a side elevation of the pad shown in FIG. 1;

FIG. 3 is a side elevation section taken through lines 3-3 of FIG. 1; and

FIG. 4 is a perspective view of the massage unit showing the convergence of the axes of protrusion of the mounted pads.

With reference to the FIGS., the unit comprises a triangular body A with three projecting pads B located at the corners. Undersurface C of body A adjoining pads B is concave defining an arcuate contour approximating that of the human head.

Pads B protrude outwardly at the corners of the body and have arcuate surface contact areas of relatively large radius curvature. These areas have a curvature adapted to contact the body at their central portion spreading the force applied through the massage unit'to the scalp over a relatively large area.

The pads of massage unit B are separated one from another by distances exceeding at least three times their respective diameter of each pad. This distance of separation gives the unit a wide based three cornered support when the pad is moved over the scalp surface, which three cornered support simultaneously prevents rocking of the unit within the user's hand and applies at each pad uniform pressure to the scalp.

As shown in the perspective of FIG. 4, the respective axes of protrusion of the pads converge normally from the comers of the unit and extend outwardly from the unit to a point of convergence P. These axes of protrusion directs each pad downwardly on the head of the user so that contact between the pad and the users scalp takes place substantially normal to the head.

The unit is here shown integrally formed of hard rubber, plastic, or the like. This integral formation is preferred as it assures that there are no interfaces or cracks in the device which may subsequently become entangled with the human hair during massage. The plastic or hard-rubber is selected to maintain the curvature of the pads during their contact with the scalp and provide the pads with a coefficien't of function wherein the can easily slide over the human hair and skin of the scalfp. he triangular shape of body A is particularly suited or holding in the hand. Typically, the unit :is placed with its concave upper surface D within the palm and one of its sides grasped at the four fingers. The corner opposite the grasped side is placed within the curl of thethumb. When so held, the massage unit can be readily'moved over the scalp while simultaneously being pressed downwardly to provide a soothing massage.

Iclaim:

1. A hand-held scalp massage unit comprising a body portion generally triangular in plan and formed with a concave contoured undersurface defining an arcuate contour approximating the contour of a human head; three substantially equidistantly spaced contact pads located adjacent the three corners of the triangular shaped body and projecting outwardly from the concave contoured undersurface thereof; the outer ends of each contact pad being arcuately contoured; the minimum spacing between the contact pads being not less than substantially three times the diameter of the contact pads so as to stabilize the massage unit against rocking motion in the user's hand during use and expedite the users ability to transmit uniform massage pressure to the scalp via the three contact pads.

2. The combination of claim 1 and wherein the outer ends of the pads define rounded contact surface areas of relative large radius of curvature adapted to contact the scalp at their central portion over a relatively large area of each pad.

3. The combination of claim land wherein the axes of protrusion of the pads extend radially downwardly and convergently from said arcuate undersurface of the body.

4. The combination of claim 1 and wherein said body and said contact pads are integrally formed.
