Description

FIELD OF THE INVENTION

The present invention is in the field of massagers and plastic injection molding.

DISCUSSION OF RELATED ART

A variety of different massagers have protrusions and protections simulate fingers. Black in U.S. Pat. No. 10,322,057, has spikes arranged on flowers which are attached to a bar or other device. The primary drawbacks are that the attachment concentrates the load of multiple fingers on a weak attachment point resulting in frequent structural failure. Another flaw is its multi piece construction which adds cost and complexity and there is no easy way it can be molded in a single press. Instead the device must be constructed from several pieces, resulting in increased cost and reduced reliability.

This inability to be manufactured by injection or other type of molding process in a very simple and inexpensive mold is indeed a fatal flaw in U.S. Pat. No. 10,322,057 and other prior art. Much of this complexity is due to the need to make handholds for the use of the device. Good holding ability is critical for ease of use in this type of tool, because during the use of the device oil or other lubricants are used on the skin making the tool very slippery to hold while applying proper pressure.

For example in United States patents D384,157, D447,809, D556,913 and D633,217 the massagers sacrifice the ability to form in simple mold in order to give the user some type of grip. Also, DeLuca in the U.S. Pat. No. 5,103,809 lacks an integrated grip, although it describes an external attachment. Similarly U.S. Pat. No. 1,713,756 has no finger grooves and thus is not suitable for this use without additional attachments. As seen from Goates in United States patent 965,564 there are no useable finger grips or contours.

SUMMARY OF THE INVENTION

The present invention also includes the method of manufacture with a suggested a plane and parting line through the part, such that the device tapers away as it gets further from the parting line. The present invention provides for a device specially adapted for fascia tissue massage. The present invention has a pluralty of fingers formed as fingers which terminate in a rounded end that allows gentle fascia tissue massage. One more advantage of this device is its rugged construction. The preferred embodiment of the present invention utilizes injection molding, to maintain low cost high volume production. The top and bottom of the mold are separated by a single plane so as to allow simple injection molding. Additional objects of the invention are to allow the part to be made in a single shot mold, to provide finger holds at holes, to provide a body shape that allows holding, and to provide multiple fingers for pressure application.

A fascia massager has a main body which has a rounded a main body top portion and a flat lower portion on a main body bottom. Fingers are formed on the main body along the main body bottom. The fingers protrude downwardly from the main body bottom. The fingers have a conical finger taper. A first hexagonal frame and a second hexagonal frame are formed on the main body. The fingers extend downwardly as fingers having indents between the fingers. The fingers are parallel to each other. The indents are formed on sides of the main body.

Preferably, the fingers terminate in a rounded end. The main body has two finger holes passing through the main body. The fingers have an axis generally perpendicular to the flat portion of the main body. The fingers have a taper in a direction that allows release from a lower mold during plastic injection molding. The fascia of the device has a parting line corresponding to the flat portion of the main body. The massager has a rounded a main body top portion above the parting line which releases from the upper mold. The fingers have finger tapers with rounded ends. The fingers begin at the parting line and extend downwardly as fingers having a rounded ends, which release from the lower mold during plastic injection molding.

The main body has finger holes passing through the main body. The finger holes have a finger hole taper for mold release. The indents on the main body are arc shaped indentations curving inwardly from each consecutive finger to form side grips. The indents are concave and vertically oriented such that they have an arc shape profile when viewed from a top or bottom view.

The lower mold has finger hole spacer upper tips that extend upwardly from the lower mold. The finger hole spacer upper tips are wedge-shaped and wedge into finger hole spacer indents which are also wedge shaped. The fascia massager is made by the step of having the finger hole spacer indents align the upper mold to the lower mold during plastic injection molding.
