Abstract

Claims (38)

1 . A method for attaching an aiming device to a putter head, wherein an attachment tool includes a pair of parallel arms separated by a distance, each arm includes a channel, the channels face each other and the aiming device includes first and second edges, said method comprising the steps of:

positioning the first and second edges of the aiming device in a respective one of the channels;

sliding the edges of the aiming device in the channels, wherein there is a loose friction fit between the aiming device and the attachment tool;

manipulating the attachment tool and aiming device to be proximate the putter head;

aligning the attachment tool and aiming device fitted therein with a desired location on the putter head and a front face of the attachment tool with a front face of the putter head;

positioning the front face of the attachment tool against the front face of the putter head and positioning a bottom of the aiming device against a top of the putter head; and

sliding the tool orthogonally away from the front face of the putter head.

2 . The method according to claim 1 , said sliding step comprising pushing the aiming device between the first and second arms such that the first and second edges engage with and slide within the respective one of the channels until a first end of the aiming device is flush against a front face of the body.

3 . The method according to claim 1 , said positioning step further comprising pressing the aiming device against the top of the putter head to removably attach the aiming device to the putter head.

4 . The method according to claim 1 , wherein the aiming device includes a cut out and the putter head includes an aiming line, said aligning step further comprising aligning the cut out with the aiming line.

5 . An attachment tool for attaching an aiming device to a putter head comprising:

a body having a front face, a first side, and a second side;

a first cantilever extending orthogonally away from the front face proximate the first side;

a second cantilever extending orthogonally away from the front face proximate the second side; and

each of the first and second cantilevers includes a first end, a terminus, a front surface, a rear surface, a bottom, a top, a ledge extending along the bottom, and a member extending along the top, wherein

the first cantilever front and rear surfaces extend from the first end to the terminus of the first cantilever,

the front surface, ledge, and member of the first cantilever form a first channel,

the second cantilever front and rear surfaces extend from the first end to the terminus of the second cantilever,

the front surface, ledge, and member of the second cantilever form a second channel,

the first and second channels face each other and are separated by a distance,

the front surface of the first cantilever includes a first guide portion,

the first guide portion extends from the first cantilever terminus to an end of the first cantilever member,

the front surface of the second cantilever includes a first guide portion,

the second cantilever first guide portion extends from the second cantilever terminus to an end of the second cantilever member,

the first cantilever member includes a second guide portion, the second guide portion extends from the end of the first cantilever member towards the first channel,

the second cantilever member includes a second guide portion, the second cantilever second guide portion extends from the end of the second cantilever member towards the second channel,

the first guide portion of the first and second cantilevers is configured to guide an aiming device horizontally into the first and second channels, and

the second guide portion of the first and second cantilever members is configured to guide the aiming device vertically into the first and second channels.

6 . The attachment tool according to claim 5 , wherein:

the first guide portion of the first and second cantilevers is arcuate or a straight-line taper; and

the second guide portion of the first and second cantilevers is arcuate or a straight-line taper.

7 . The attachment tool according to claim 5 , wherein the body, first cantilever, and second cantilever are manufactured from at least one of plastic, nylon, aluminum, metal and wood.

8 . The attachment tool according to claim 5 , wherein the first and second channels are C-shaped or U-shaped.

9 . The attachment tool according to claim 5 , wherein:

the first and second channels are configured to slidingly receive an aiming device;

the aiming device includes a bottom surface and an adhesive on the bottom surface, the adhesive has a thickness; and

the thickness of the adhesive is greater than or equal to a thickness of the first cantilever ledge and the second cantilever edge.

10 . The attachment tool according to claim 5 , wherein the body, the first cantilever, and the second cantilever are integrally formed.
