Coating for golf club head

USPTO Application #: 20050272522
Title: Coating for golf club head
Abstract: A coating includes a bottom paint layer coated on a surface of the golf club head and an elastomeric resin layer coated on the bottom paint layer, with the elastomeric resin layer containing quenchers. When light beams are incident on the elastomeric resin layer, the quenchers provide a double scattering effect for the light beams passing therethrough and thus reduce the intensity of the light beams reflected from the bottom paint layer.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a coating for a golf club head. In particular, the present invention relates to a coating on a golf club head for scattering light beams incident on the golf club head.

[0003] 2. Description of Related Art

[0004] Golf is an outdoor game and the sunlight incident on the golf club head is sometimes reflected to the eyes of a golfer hitting a golf ball. Thus, the golfer might be distracted and thus miss the aim. FIG. 1 of the drawings illustrates a golf club head with a bottom paint layer 2 on a surface 1 thereof. The bottom paint layer 2 contains quenchers 21 to provide not only anti-rust/decoration functions but also increased light-scattering power, softening the reflected light beams and thus preventing the golfer from missing his/her aim.

[0005] However, since the outer face of the bottom paint layer 2 still reflects sunlight incident thereon and since there are only few quenchers 21 exposed at the outer face of the layer of bottom paint 2, most of light beams incident on the outer face of the layer of bottom paint 2 are directly reflected. Namely, the scattering effect is limited, as the quenchers 21 not on the outer face of the layer of bottom paint 2 are not effectively used. Further, in a case that some of the light beams are incident on the defects 22 on the golf club head, since the incident light beams are subjected to limited scattering, the reflected light beams still have sufficient brightness such that the defects 22 on the golf club head will be perceived by the golfer. Additional polishing procedure to the surface 1 of the golf club head is required or the golf club head will be treated as a disqualified one.

OBJECTS OF THE INVENTION

[0006] An object of the present invention is to provide a coating on a surface golf club head, providing a double scattering effect for improving the surface scattering effect.

[0007] Another object of the present invention is to provide a coating on a surface of a golf club head to improve the visual effect.

[0008] A further object of the present invention is to provide a coating on a surface of a golf club head to improve the touch.

[0009] Still another object of the present invention is to provide a coating on a surface of a golf club head with a durable bottom paint layer.

[0010] Yet another object of the present is to provide a coating on a surface of a golf club head with improved damping effect.

SUMMARY OF THE INVENTION

[0011] In accordance with an aspect of the present invention, a coating includes a bottom paint layer coated on a surface of the golf club head and an elastomeric resin layer coated on the bottom paint layer, with the elastomeric resin layer containing quenchers. When light beams are incident on the elastomeric resin layer, the quenchers provide a double scattering effect and thus reduce the intensity of the light beams reflected from the bottom paint layer.

[0012] The bottom paint layer is selected from the group comprising phenolic paint, alkyd paint, polyurethane paint, nitrocellulose paint, and acrylic paint. The bottom paint layer preferably has a thickness between 10 .mu.m and 100 .mu.m.

[0013] The elastomeric resin layer is made of a material selected from the group comprising polyurethane, rubber, thermoplastic elastomer, and high molecular elastomeric resin. The elastomeric resin layer preferably has a thickness between 20 .mu.m and 200 .mu.m.

[0014] Preferably, the quenchers are fine powders of a material selected from the group comprising silicon dioxide, talcum, aluminum stearate, calcium stearate, and low molecular thermoplastic resin.

[0015] The elastomeric resin layer may further contain a hardening agent for accelerating hardening of the elastomeric resin layer.

[0016] Other objects, advantages and novel features of this invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG. 1 is a schematic view illustrating a conventional coating on a golf club head; and

[0018] FIG. 2 is a schematic view illustrating a coating on a golf club head in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0019] Preferred embodiments of the present invention are now to be described hereinafter in detail.
