[0035] Existing weight systems may have a large area of the system uncovered or exposed. This may create an undesirable look and negatively affect aerodynamics, center of gravity (CG), moment of inertia (MOI), and / or other golf characteristics. Some weight systems may use a cover that causes inefficiencies in mass, which may push weight upward, which in turn may push the CG upward. Other weight systems may hide positions of a weight.

[0036] The presently disclosed technology described herein contemplates a golf club head, such as an iron, a fairway wood, a driver, or another type of golf club head, that includes tiled weighting. The tiled weighting system may include spacer tiles and a weighted tile. The spacer tiles may be installed, and a cover added to prevent the spacer tiles from falling out. The spacer tiles may be slidable along a sole groove. The weighted tile may fit against at least one of the plurality of spacer tiles in a plurality of positions. The plurality of positions may correspond to the total number of tiles, which may include spacer tiles and weighted tile. At least one of the plurality of spacer tiles may engage the weighted tile. The plurality of spacer tiles and the weighted tile may combine to substantially cover the sole groove. In the installed position, the weighted tile may engage at least one adjacent spacer tile to secure the weight assembly to the golf club head. The presently disclosed technology may provide a weight system that is low profile, flush, mass efficient, and / or improve CG. The presently disclosed technology may provide mass redistribution benefits, structural integrity benefits, aerodynamic benefits, and / or other golf club performance benefits.

[0037] Establishing a reference coordinate system for the presently disclosed technology, an x-axis may refer to the axis that is horizontal to the face from a heel-to-toe direction, a y-axis may refer to the vertical axis through the club in a crown to sole direction, a z-axis may refer to the horizontal axis that is horizontal front to back in a forward and rear direction. Alternatively speaking, the x-axis may be defined as a horizontal axis tangent to a geometric center of the face with the positive direction towards a heel of the golf club head, a y-axis is a vertical axis orthogonal to the x-axis with a positive direction towards a top of the golf club head, and a z-axis being orthogonal to both the x-axis and the y-axis with a positive direction towards a front of the golf club head. The x-y-z coordinate system described above shall be the same for all subsequent discussions. For example, the x-y-z coordinate system may be used to describe the CG of the golf club head. The golf club head may have a CG-x, a CG-y, and a CG-z component corresponding to the x-, y-, and z-coordinates discussed herein.

Each of spacer tiles 112 may include rails 130 on a front end and a back end of spacer tiles 112. Rails 130 may be protrusions on spacer tiles 112. Rails 130 may fit into undercuts 128. Rails 130 may help prevent spacer tiles 112 from falling out of sole groove 108 in the installed position. In embodiments, rails 130 may be spring-loaded, allowing rails 130 to be collapsed and installed. Referring to FIG. 8, an individual spacer tile 112 may include rails 130, first feet 150, first ramps 151, second foot 152, and / or second ramp 153. First ramps 151 and second ramp 153 may be collectively referred to as ramps. First feet 150 and second foot 152 may be collectively referred to as feet. First feet 150 may interact with first ramps 151. For example, in the installed position, first feet 150 of a first spacer tile 112 may fit over first ramps 151 of an adjacent spacer tile 112. Second foot 152 may interact with second ramps 153. For example, in the installed position, second foot 152 of a first spacer tile 112 may fit over second ramp 153 of an adjacent spacer tile 112. In some embodiments, first feet 150 and / or second foot 152 of a first spacer tile 112 may slide over first ramps 151 and / or second ramp 153 of adjacent spacer tiles 112, respectively. This may cause them to interlock together. These same features may allow spacer tiles 112 to be slidable across sole groove 108 without weighted tile 114. Rails 130 may help enable this sliding. In some embodiments, the feet and ramps may include polymeric bumpers to fill any tolerance gaps between tiles. In the installed position, top sides of spacer tiles 112 may be empty. For example, there is no material extending on a top side of spacer tile 112. For the sake of clarity, assuming spacer tile 112 was shaped like a box, the top of the box is open, as illustrated in FIG. 4. Spacer tiles 112 may be less than about 2 g. In some embodiments, spacer tiles 112 may be less than about 1 g. Referring back to FIG. 1, while four spacer tiles 112 are illustrated, it should be appreciated that there may be more or fewer spacer tiles 112 without departing from the spirit and scope of the presently disclosed technology.
