Description

[Technical field]

[0001] This claims the benefit of priority to U.S. Provisional Application No. 63 / 257,037, filed October 18, 2021, which is incorporated by reference herein in its entirety.

[0002] FIELD OF THE DISCLOSURE The present disclosure relates to golf clubs and, more particularly, to golf clubs having a sensor disposed within a sensor housing. [Background technology]

[0003] Golf clubs can be fitted with sensors that record a golfer's shots and can be paired with a smartphone app to view the shot data. The sensor can be secured within a sensor housing that screws into the distal end of the grip. However, the sensor housing can be an intrusive addition to the end of the golf club. The sensor housing adds mass and length to the grip of the golf club and can change the center of gravity (CG) of the golf club. Some sensor housings protrude beyond the end of the grip footprint and do not comply with USGA rules. For golfers who grip near the distal end, this protrusion can be in the way during the swing. Additionally, the sensor housings can be difficult to manufacture. Some sensor housings require the sensor to be secured with an adhesive, which adds to the structural weight of the sensor housing. Thus, there is a need in the art for a sensor housing that is easy to manufacture and unobtrusive.

Summary of the Invention [Means for solving the problem]

[0006] Some golf club grips are configured to receive a sensor for recording shot data. The sensor is enclosed in a sensor housing, which is received by the grip. The present invention is a sensor housing designed to be unobtrusive and easy to manufacture. The sensor housing includes a base below the sensor and a cover positioned to cover the sensor and fastened to the base. The base includes a post, which is received by the grip and secures the sensor housing to the grip. The sensor housing remains within the perimeter of the grip to comply with USGA rules and to prevent the golfer from being distracted by the sensor. To achieve this configuration, the post is offset to move the sensor housing toward the front of the grip. The grip is wider near the front to accommodate a larger portion of the sensor housing than the rear.

[0007] The sensor housing also minimizes its effect on the center of gravity (CG) of the golf club by including features that reduce mass and by reducing the length the sensor housing adds to the grip. The sensor housing can be positioned flush with the grip such that at least 50% of the sensor housing base contacts the surface of the grip. The sensor housing can include ribs to secure the sensor, which reduces mass compared to a solid ring of material. The sensor housing is also configured to sit low on the grip and reduce the length it protrudes outward from the distal end of the grip. Reducing the additional length from the sensor housing creates a less intrusive feature.

[0008] The sensor housing is also constructed to securely hold the sensor in place. The cover and base are constructed to flex slightly as they are fastened together while being rigid enough to protect the sensor. Once fastened, the cover and base cannot be removed. The cover and base are designed with a non-removable connection to provide a secure housing for the sensor that cannot be easily disassembled.

[0009] The sensor housing also provides a threaded post configured to interface with an opening in the grip. The threaded post screws into the opening in the grip to securely and unobtrusively secure the sensor housing onto the distal end of the grip. The thread is formed from the same material as the post and base in a single mold, providing manufacturing advantages. The thread can include a thickened section that helps retain the post within the grip opening.

[0010] The sensor housing also provides manufacturing advantages. The sensor housing reduces the structural weight of the sensor housing because the sensor does not need to be secured with adhesives. The cover and base are formed separately and therefore can be made of different materials, and the base can be easily formed with the post. The sensor housings described herein can be used in a variety of sporting goods such as golf clubs, bats, and racquets.

[0011] As used herein, "longitudinal axis" refers to an axis extending through the grip from the geometric center of the grip distal end to the geometric center of the grip distal end.

[0012] As used herein, the "grip opening axis" refers to an axis that extends through the center of the grip opening.

[0013] As used herein, the term "grip perimeter" refers to the surface of the grip near the distal end that is bounded by the grip edges. The grip perimeter is essentially the surface area that is visible when the grip is viewed from the distal end.

[0014] The "cross-sectional shape" of a grip, as described herein, is the shape of the grip as defined within the outer boundary and viewed in a plane perpendicular to the longitudinal axis. Because the grip is flexible, the cross-sectional shape will change slightly when the grip is attached to a shaft. The size of the shaft will also affect the dimensions of the attached grip.

[0015] As used herein, a "sensor" refers to a shot recorder located near the distal end of the grip. The sensor may be fixed within a sensor housing.

[0016] The grip can define a length measured along the longitudinal axis from the distal end to the distal end. The grip length can be between 9.5 inches and 11.5 inches. In some embodiments, the grip length can be 9.5 inches, 9.75 inches, 10 inches, 10.25 inches, 10.5 inches, 10.75 inches, 11 inches, 11.25 inches, or 11.5 inches. The end cap can increase the length of the grip, making it longer than a grip without the sensor. In one embodiment, the end cap can increase the length of the grip by 0.41 inches.

[0017] The terms "include," "have," and variations thereof are intended to be non-exclusively inclusive, and a process, method, system, article, apparatus, or device comprising a list of elements is not necessarily limited to those elements, and may include other elements that are not expressly listed or that are inherent to such process, method, system, article, apparatus, or device.

[0018] Where terms such as "top," "upper," "lower," "upper," "lower," "inner," "outer," "maximum," "tapered," "beveled," and the like are used in this specification and in the claims, they are used for descriptive purposes and not necessarily to describe permanent relative positions. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are operable, for example, in orientations other than those illustrated or otherwise described herein.

[0019] The terms "coupled," "coupled," "connecting," and the like should be understood broadly and refer to connecting two or more elements or signals in an electrical, mechanical, and / or other manner.

[0020] For simplicity and clarity of illustration, the drawings show general structural aspects, and descriptions and details of well-known features and techniques may be omitted to avoid unnecessarily obscuring the present invention. Additionally, elements in the drawings are not necessarily drawn to scale. For example, the dimensions of some elements in the drawings may be exaggerated relative to other elements to help understand embodiments of the present invention. The same reference numerals in different drawings refer to the same elements. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] (Detailed Description) Described herein are various embodiments of a sensor housing that encloses a sensor and is configured to be secured to the distal end of a grip of a golf club. The position of the sensor housing is not distracting or intrusive to the user during a swing. Referring to the drawings, Figs. 1 and 12 show various embodiments of the sensor housing as described herein. The features described below are shown in a sensor housing 100. For ease of discussion, like reference numerals are used to identify like or identical components in the various embodiments of the sensor housing according to the present invention. Any one or more of the features described below may be used in combination with each other.

[0022] 3 and 4, the sensor housing 100 includes a cover 120 and a base 150 that are fastened together to enclose the sensor 20. In some embodiments, the base 150 includes a plurality of tabs 158 that are received within a plurality of windows 128 defined in the cover 120. In these embodiments, the tabs 158 and the windows 128 facilitate connection between the base 150 and the cover 120. To secure the sensor housing 100 to the grip 10, the base 150 further includes a post 160 that is received through an opening 18 defined by the grip 10 (the "grip opening"). The structure of the sensor housing 100, as well as the positioning of the sensor housing 100 relative to the grip opening 18, are described in further detail below.

[0023] One important feature of the sensor housing design is the positioning of the sensor housing 100 relative to the grip distal end 12. The sensor housing 100 is designed to be unnoticeable to the user (hereinafter "unobtrusive") so as not to feel awkward or intrusive when gripping the grip 10. To achieve the unobtrusive configuration, the sensor housing 100 does not extend beyond the grip perimeter 17, as shown in Figures 1 and 2. In other words, the sensor housing 100 remains within the grip perimeter 17 such that the user does not notice the sensor housing 100 when holding the grip.

[0024] FIG. 2 is a top (or end) view of the grip 10 with the sensor housing 100 installed. In the top view, the outer surface of the grip 10 defines a grip perimeter 17. The grip perimeter 17 defines the circumferential area of ​​the grip 10 where the user holds the grip 10. The various embodiments of the sensor housing 100 described herein are designed to remain within the grip perimeter 17 so that the user does not notice the sensor housing 10 during the swing. FIGS. 1 and 2 show that the sensor housing 100 does not extend beyond the grip front side 14, the grip back side 16, or the sides of the grip 10. A uniform, consistent surface with no outwardly protruding sensor housings provides a preferred tactile feel for golfers who wish to maintain a seamless feel during their golf swing.

[0025] Various aspects of both the sensor housing 100 and / or the grip 10 can be adjusted to achieve this positioning. In some embodiments, the location of the grip opening 18 can be selected to carefully position the sensor housing 100 within the grip perimeter 17. The location of the grip opening 18 depends on the cross-sectional shape of the grip 10. As such, certain grips require the position of the grip opening 18 to be adjusted in order to position the sensor housing 100 within the grip perimeter 17. Some grips 10 have a symmetrical cross-sectional shape, which allows the grip opening 18 and the sensor housing 100 to be centered in the grip end portion 12. For example, some grips 10 can have a symmetrical circular cross-sectional shape and can accommodate a symmetrical sensor housing. Other grips 10 can have an asymmetrical cross-sectional shape that requires repositioning of the grip opening 18. For example, the grip 10 shown in FIG. 2 is wider near the grip front side 14 and narrows toward the grip rear side 16. In these embodiments, the grip opening 18 is positioned near the grip front side 14 in order to position the sensor housing 100 in the wider forward portion of the grip 10. The location of the grip opening 18 can be adjusted on any given grip 10 to optimally position the sensor housing 100. The grip opening 18 can be located in a front-to-back offset position and / or a heel-to-toe offset position.

[0026] The position of the grip opening 18 in the front-rear direction is the first opening offset O A1 With reference to FIG. 1, the aperture offset O A1 is measured in the front-to-rear direction as the distance from the grip opening axis 30 to the longitudinal axis 40. FIG. 1 illustrates a grip opening 18 that is located closer to the grip front side 14 and therefore has a greater forward opening offset O. A1 However, in other embodiments, the grip opening 18 may be located closer to the grip rear side 16, with the rearward opening offset O A1 In many embodiments, the aperture offset OA1 is between 0.010 inches and 0.100 inches. In some embodiments, the aperture offset O A1 , between 0.010 inches and 0.050 inches, between 0.025 inches and 0.075 inches, between 0.050 inches and 0.060 inches, or between 0.055 inches and 0.100 inches. A1 is approximately 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, or 0.100 inches. In one exemplary embodiment, the aperture offset O A1 is 0.060 inches. Aperture offset O A1 depends on the size and cross-sectional shape of the grip 10. In many embodiments, the first opening offset O A1 helps to deal with asymmetrical grips. First opening offset O A1 is the first post offset O, as detailed below. P1 Together, the first aperture offset O A1 , and the first post offset O P helps position the sensor housing 100 within the grip perimeter 17.

[0027] In many embodiments, the grip opening 18 is centered in the heel-toe direction. However, in some embodiments, the grip opening 18 may be located closer to either the heel or the toe. In these embodiments, the location of the grip opening 18 in the heel-toe direction is determined by the second opening offset O. A2 The second aperture offset O A2 is measured in a heel-to-toe direction as the distance from the grip opening axis 30 to the longitudinal axis 40 (not shown). A2is between 0.010 inches and 0.100 inches. In some embodiments, the aperture offset O A2 is between 0.010 inches and 0.050 inches, between 0.025 inches and 0.075 inches, between 0.050 inches and 0.060 inches, or between 0.055 inches and 0.100 inches. In some embodiments, the aperture offset O A2 is about 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, or 0.100 inches. A2 depends on the size and cross-sectional shape of the grip 10. In many embodiments, the second opening offset O A2 helps accommodate asymmetrical grips. Secondary opening offset O A2 The second post offset O is described in detail below. P2 Together, the second aperture offset O A2 and the second post offset O P2 helps position the sensor housing 100 within the grip perimeter 17 and align the post 160 with the grip opening 18 .

[0028] The grip opening 18 comprises a grip opening diameter measured across the opening (not shown). In many embodiments, the grip opening diameter is between 0.10 inches and 0.14 inches. In some embodiments, the grip opening diameter is between 0.10 inches and 0.13 inches, 0.11 inches and 0.13 inches, or 0.12 inches and 0.14 inches. In some embodiments, the grip opening diameter is about 0.10 inches, 0.11 inches, 0.12 inches, 0.13 inches, or 0.14 inches. In one exemplary embodiment, the grip opening diameter is about 0.125 inches. The grip opening diameter corresponds to a post diameter such that the post 160 is received within the grip opening 18. The post 160 is received within the grip opening 18 such that it is tightly connected. The connection between the post 160 and the grip opening 18 is tight enough to allow the sensor housing 100 to be press-fit into the grip 10. In some embodiments, the grip opening 18 is threaded to receive a threaded post 160, as shown in FIG. 1. In other embodiments, the grip opening 18 is not threaded. The size and location of the grip opening 18 is selected to position the sensor housing 100 out of the way for a user while gripping the grip 10. Additionally, the grip opening 18 is configured to receive the sensor housing 100 and securely secure it in place.

[0029] Another important feature of the sensor housing design is the flexible yet rigid construction of the sensor housing 100. The sensor housing 100 provides a sturdy structure for the sensor 20 while allowing the sensor housing to be assembled onto the sensor 20. As described above, the sensor housing 100 comprises a cover 120 and a base 150 that interlock to enclose the sensor 20. With reference to Figures 1 and 3, the sensor 20 is disposed within a sensor cavity 102 defined between the cover 120 and the base 150. The cover 120 and the base 150 are configured to flex slightly to interlock while being sufficiently rigid to protect the sensor 20. In many embodiments, the cover 120 and the base 150 are not removable once fastened and constitute a permanently constructed assembly.

[0030] As discussed above, the cover 120 is designed to wrap around the top of the sensor 20, and the base 150 sits underneath the sensor 20 and secures the sensor housing 100 to the grip 10. The sensor 20 is placed onto the base 150, and the cover 120 is placed over the sensor 20 and snapped into place. The interaction between the cover 120 and the base 150 can be facilitated by various interacting or corresponding features located on the cover 120 and base 150. As described in more detail below, this interaction can be facilitated by corresponding tabs and windows, corresponding notches and recesses, or any other suitable features.

[0031] Once assembled, the sensor housing 100 is placed into the grip opening 18, carefully positioned so that the sensor housing 100 does not protrude beyond the grip perimeter 17. In many embodiments, the sensor housing 100 is designed to fit the placement of the grip opening 18. In some embodiments, the base 150 is designed to shift the sensor housing 100 closer to the grip front side 14.

[0032] 9-11 , the base 150 includes a disk 152 and a post 160 extending from the disk 152. The post 160 is integrally formed with the disk 152 via a single flat parting line mold. The disk 152 is the portion of the base 150 that is secured to the cover 120, and the post 160 is secured within the grip opening 18.

[0033] 9 and 10, the disk 152 includes a top surface 154, a bottom surface 156 opposite the top surface 154, and a perimeter 157 that defines an outer edge of the disk 152. In many embodiments, the disk top surface 154 is a substantially flat surface that supports the sensor. With reference to FIG. 1, the disk top surface 154 is adjacent the bottom surface of the sensor 20, and the disk bottom surface 156 is adjacent the grip 10.

[0034] In some embodiments, the disk 152 further comprises a number of tabs 158 (hereafter referred to as "tabs") projecting from the outer periphery 157. The tabs 158 project from the outer periphery 157 so as to be parallel to the disk top and bottom surfaces 154, 156. The tabs 158 are received within a number of windows defined by the cover 120, as shown in Figures 3 and 4. In this manner, the tabs 158 can allow the disk 152 (and base 150) to be received within the cover 120. The base 150 and cover 120 are formed separately and fastened together on the sensor 20. Once in place, the base 150 and cover 120 are non-removable from one another. The non-removable connection between the cover 120 and the base 150 provides a robust sensor housing 100 without the need for adhesive materials. In many embodiments, the tabs 158 are shaped such that the base 150 and cover 120 can be fastened together without removing them.

[0035] In many embodiments, the tabs 158 define a rectangular or trapezoidal shape in cross-section or side view. For example, FIG. 11 illustrates one embodiment of the tabs 158, where the tabs 158 define a trapezoidal shape in side view. In these embodiments, the tab top surface 159 is chamfered and the tab bottom surface 161 is flat. The tab top surface 159 may be chamfered to allow the tabs 158 to slide into place when received in the cover 120. In many embodiments, the tab bottom surface 161 may be flat to prevent the base 150 from being removed from the cover 120. In some embodiments, each tab 158 has the same shape as an adjacent tab 158, as illustrated in FIG. 11. In other embodiments, each tab 158 has a different shape than an adjacent tab 158. In many embodiments, the tabs 158 may have a shape similar to the shape of a corresponding window 128 to allow the corresponding window 128 to receive the tab 158. The tabs 158 provide a lightweight mechanism for securing the base 150 to the cover 120. Thus, the tabs 158 help provide an unobtrusive sensor housing 100 by not significantly increasing the structural mass of the sensor housing 100 .

[0036] The disk 152 can have any suitable number of tabs 158 to allow the cover 120 to be secured to the base 150. For example, the disk 152 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 tabs. In some embodiments, the disk 152 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more tabs. FIGS. 9 and 10 show an embodiment of the base 150 in which the disk 152 has four tabs 158. In most embodiments, the number of tabs 158 corresponds to the number of windows 128 disposed in the cover 120. In some embodiments, the tabs 158 are equally spaced from one another. In other embodiments, the tabs 158 are not equally spaced from one another. The tabs 158 are disposed around the disk perimeter 157 to allow the disk 152 (and base 150) to be received in the cover 120. Thus, the size, shape, and positioning of tab 158 are selected to ensure that tab 158 is securely secured within window 128 of cover 120. In some embodiments, the shape, dimensions of tab 158 change the dimensions of disk 152.

[0037] The disk 152 has a diameter measured through the center of the disk 152 across the disk top surface 154 (not shown). In many embodiments, the disk diameter is between 0.70 inches and 0.90 inches. In some embodiments, the disk diameter is between 0.70 inches and 0.80 inches, 0.75 inches and 0.90 inches, or 0.80 inches and 0.90 inches. In some embodiments, the disk diameter is about 0.70 inches, 0.71 inches, 0.72 inches, 0.73 inches, 0.74 inches, 0.75 inches, 0.76 inches, 0.77 inches, 0.78 inches, 0.79 inches, 0.80 inches, 0.81 inches, 0.82 inches, 0.83 inches, 0.84 inches, 0.85 inches, 0.86 inches, 0.87 inches, 0.88 inches, 0.89 inches, or 0.90 inches. In one exemplary embodiment, the disk diameter is 0.79 inches. In some embodiments, the diameter of the disk 152 may vary depending on the presence of features such as tabs or recessed portions. For example, FIG. 9 shows one embodiment of the disk 152, where the diameter is larger near the portion having the tab 158. As will be described in more detail below, FIG. 18 illustrates another embodiment of the disk 252, where the diameter is smaller near the recessed portion 290. In many embodiments, the diameter of the disk 152 corresponds to the diameter of the cover 120, such that the cover 120 can receive the disk 152.

[0038] Referring to FIG. 11, the disk 152 further has a thickness t D In many embodiments, the thickness t D In some embodiments, the thickness t D is between 0.01 inches and 0.15 inches, between 0.10 inches and 0.20 inches, or between 0.15 inches and 0.25 inches. In some embodiments, the thickness t Dis about 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, 0.10 inches, 0.11 inches, 0.12 inches, 0.13 inches, 0.14 inches, 0.15 inches, 0.16 inches, 0.17 inches, 0.18 inches, 0.19 inches, 0.20 inches, 0.21 inches, 0.22 inches, 0.23 inches, 0.24 inches, or 0.25 inches. In one exemplary embodiment, the thickness t D In many embodiments, the thickness t D is substantially constant across the disk 152 to accommodate sensors 20 having flat bottom surfaces. However, in some embodiments, the thickness t D may vary across the disk 152. D is selected to ensure that the disk 152 is flexible yet durable enough to be inserted into the cover 120. D are also minimized to ensure that the disks 152 do not significantly add to the structural mass of the sensor housing 100. Minimizing the structural weight of each feature helps provide an unobtrusive sensor housing that does not significantly impact the center of gravity of the golf club.

[0039] The base 150 serves multiple functions for the sensor housing 100. As mentioned above, the tabs 158 form the necessary connection with the cover 120 to secure the sensor 20 therebetween. Additionally, a post 160 protruding from the disk 152 secures the sensor housing 100 to the grip 10. More specifically, the post 160 extends from the disk bottom surface 156 through the grip opening 18, thereby securing the base 150 (and the sensor housing 100) to the grip 10. The post 160 is formed along the longitudinal axis 40. In some embodiments, the post 160 is not threaded. However, in most embodiments, the post 160 is threaded to interface with the threaded grip opening 18.

[0040] As mentioned above, the sensor housing 100 is designed to remain within the grip perimeter 17 to provide an unobtrusive housing for the sensor 20. Depending on the size and shape of the grip 10, various features of the sensor housing 100 can be adjusted to position the sensor housing 100 within the grip perimeter 17. In some embodiments, the base 150 is designed to shift the sensor housing 100 closer to the grip front side 14. To shift the sensor housing 100 forward, the post 160 is positioned closer to the front side of the sensor housing 100 (closer to the grip front side 14). FIG. 8 is a side view of the sensor housing 100 showing the forward positioning of the post 160. The position of the post 160 relative to the disk 152 is referred to as the post offset O.

[0041] The position of the post 160 in the front-to-rear direction is determined by the first post offset O P1 Referring to FIG. 8, the first post offset O P1 is measured in the front-to-rear direction as the distance from the post axis 50 to the central axis 60 of the sensor housing 100. FIG. 8 shows the post 160 positioned closer to the grip front side 14, and therefore the forward post offset O P1However, in other embodiments, the post 160 can be located closer to the grip rear side 16, with a rearward post offset O. P1 In many embodiments, the first post offset O P1 is between 0.010 inches and 0.100 inches. In some embodiments, the first post offset O P1 is between 0.010 inches and 0.050 inches, between 0.025 inches and 0.075 inches, between 0.050 inches and 0.060 inches, or between 0.055 inches and 0.100 inches. In some embodiments, the first post offset O P1 is about 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, or 0.100 inches. In one exemplary embodiment, the first post offset O P1 is 0.060 inches. First post offset O P1 is the first aperture offset O, as will be explained in more detail below. A1 The first post offset O P1 depends on the size and cross-sectional shape of the grip 10. Taken together, the first opening offset O A1 and the first post offset O P1 helps position the sensor housing 100 within the grip perimeter 17.

[0042] In many embodiments, the post 160 is located in the center of the disk 152 in the heel-toe direction. For example, FIG. 7 shows a front view of the sensor housing 100 with the post 160 located in the center of the disk 152 in the heel-toe direction. However, in some embodiments, the post 160 may be located closer to either the heel or the toe. In these embodiments, the location of the post 160 in the heel-toe direction is determined by the second post offset O. P2 The second post offset O P2 is measured in a heel-to-toe direction as the distance from the post axis 50 to the central axis 60 of the sensor housing 100 (not shown). In many embodiments, the second post offset O P2 is between 0.010 inches and 0.100 inches. In some embodiments, the second post offset O P2 is between 0.010 inches and 0.050 inches, 0.025 inches and 0.075 inches, 0.050 inches and 0.060 inches, or 0.055 inches and 0.100 inches. In some embodiments, the second post offset O P2 is about 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, or 0.100 inches. P2 depends on the size and cross-sectional shape of the grip 10. Second post offset O P2 is the second aperture offset O, as described in more detail below. A2 Together, the second aperture offset O A2 and the second post offset O P2helps position the sensor housing 100 within the grip perimeter 17. As discussed above, the positioning of the post 160 relative to the base 150 helps position the sensor housing in a desired, out-of-the-way location on the grip 10.

[0043] Another important feature of the post design is the shape of the post threads 162. With reference to Figures 8 and 9, the threads 162 have a number of thickened regions 164 formed along the post axis 50. The thickened regions 164 further stabilize the connection between the post 160 and the grip 10 by preventing the post 160 from being removed from the grip opening 18 once installed.

[0044] As mentioned above, the base 150 provides several functions for the sensor housing 100. Namely, the disk 152 provides a floor for the sensor 20, and the post 160 forms a connection with the grip opening 18 to secure the sensor housing 100 to the grip 10. Various features of the base 150 can be configured to provide an unobtrusive sensor housing 100. For example, in some embodiments, the post 160 can be positioned so that the sensor housing 100 remains within the grip perimeter 17. Additionally, features of the base 150 can be designed to reduce the structural weight of the sensor housing 100 so that the sensor housing 100 does not significantly affect the center of gravity of the golf club. The cover 120 provides a sheath for the upper portion of the sensor 20, while the base 150 supports the lower portion of the sensor 20.

[0045] 12-14, the cover 120 has a hollow cylindrical portion that encapsulates the sensor 20 and is configured to mate with the base 150. In many embodiments, the cover 120 has a single, one-piece construction. The cover 120 includes a top end 121, a bottom end 122, an inner surface 125, and an outer surface 126. As discussed above, the inner surface 125 serves to define the sensor cavity 102. With reference to FIG. 3, the sensor cavity 102 is circumferentially defined by the inner surface 125, and a disk 152 (of the base 150) provides a floor for the sensor cavity 102. The sensor cavity 102 extends from the top end 121 to the disk upper surface 154. In many embodiments, the sensor cavity 102 does not extend to the bottom end 122.

[0046] The bottom end 122 is located near the grip end 12, as shown in FIG. 1. The cover 120 defines a bottom opening 124 near the bottom end 122 and is configured to receive the base 150. The bottom opening 124 is thus sized to accommodate the disk 152, as described in more detail below. The cover 120 further includes a rim 127 near the top end 121, the rim 127 extending inwardly, as shown in FIGS. 12 and 13. The cover 120 further defines a top opening 123 near the top end 121, the rim 127 forming an outer periphery of the top opening 123. The sensor 20 is exposed to the outside through the top opening 123, and the rim 127 retains the sensor 20 within the sensor cavity 102. FIG. 2 shows a top view of the grip 10, with the sensor 20 visible when the grip end 12 is viewed in a plane perpendicular to the longitudinal axis 40.

[0047] The cover 120 provides a sheath for retaining the sensor 20 within the sensor cavity 102 and is configured to receive the base 150 to enclose the sensor 20. To receive the base 150, the cover 120 further defines a plurality of windows 128 (hereinafter referred to as "windows") near the bottom end 122. With reference to FIGS. 12 and 13, the windows 128 each form an opening in the cover 120 that extends from the inner surface 125 through the outer surface 126. The windows 128 receive tabs 158 of the base 150, thereby securing the cover 120 to the base 150. The windows 128 are material-free portions of the cover 120, thereby reducing the structural mass of the sensor housing 100. As discussed above, the reduced structural mass helps provide a less obtrusive sensor housing 100 that does not significantly impact the center of gravity of the club head.

[0048] In many embodiments, the window 128 has a shape such as a rectangle or trapezoid in cross-section or side view. For example, FIG. 14 illustrates one embodiment of the window 128, in which the window 128 defines a rectangular shape in cross-section. The window 128 has a shape corresponding to the shape of the plurality of tabs 158. In many embodiments, the window 128 is shaped to prevent the base 150 from being removed from the cover 120. The window 128 thereby facilitates a strong, non-removable connection between the cover 120 and the base 150. In some embodiments, each window 128 has the same shape as an adjacent window 128, as shown in FIG. 12. In other embodiments, each window 128 has a different shape than an adjacent window 128. In many embodiments, the window 128 can have a shape similar to the corresponding tab 158 such that the window 128 can receive the tab 158.

[0049] The cover 120 can have any suitable number of windows 128 to allow the cover 120 to be secured to the base 150. For example, the cover 120 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 windows. In some embodiments, the cover 120 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more windows. FIGS. 12 and 13 show one embodiment of the cover 120, where the cover 120 has four windows 128. In most embodiments, the number of windows 128 corresponds to the number of tabs 158 disposed on the base 150. In some embodiments, the windows 128 are equally spaced from one another. In other embodiments, the windows 128 are not equally spaced from one another. The windows 128 are disposed around the periphery of the cover 120 near the bottom end 122 such that the disc 152 (and base 150) can be received by the cover 120. Thus, the size, shape, and location of window 128 is selected to ensure that tab 158 is secured securely within window 128 of cover 120 .

[0050] The cover 120 can be configured to permanently receive the base 150. As discussed above, the shape and positioning of the window 128 allows the cover to easily receive the base 150. In some embodiments, the cover 120 can be tapered, rounded, chamfered, or otherwise reshaped near the bottom opening 124 to concentrate flexing near the bottom end 122 when the base 150 is received in the cover 120. In certain embodiments, these features can help the cover 120 flex to receive the base 150.

[0051] 13 and 14, in some embodiments, the cover 120 can further include a thinned region 129 located under each window 128. The thinned region 129 can facilitate interaction between the cover 120 and the base 150 by allowing the cover 120 to flex when the tabs 158 are received in the windows 128. As mentioned above, the tabs 158 can be chamfered to allow flexion when interacting with the thinned regions 129. In many embodiments, the cover 120 and the base 150 can both flex slightly when interacting. In some embodiments, the tabs 158 can extend upright through the windows 128. A strong, non-removable connection is then formed between the tabs 158 and the windows 128. The windows 128 are sized and positioned to correspond to the tabs 158 to facilitate the connection therebetween.

[0052] In some embodiments, the window 128 is offset from the cover bottom end 122. Thus, the base 150 is above the cover bottom end 122, and a portion of the cover bottom end 122 extends beyond the base 150. With reference to FIG. 4, the disk bottom surface 156 and the cover inner surface 125 define a lower cavity 104. The lower cavity 104 extends from below the base 150 to the cover bottom end 122. The lower cavity 104 is proximate to the grip end 12. With reference to FIG. 1, the lower cavity 104 and the tapered bottom end 122 allow the sensor housing 100 to sit lower on the grip 10. The lower cavity 104 receives a portion of the grip end 12, and the cover bottom end 122 presses against the grip 10. The lower cavity 104 allows the sensor housing 100 to sit lower, thereby creating a less obtrusive sensor housing 100. 4, the lower portion of the cover 120, located below the plurality of windows 128, is solid or absent. Thus, the solid lower portion (of the cover 120) and tapered bottom end 122 help seal the sensor housing 100 to the grip 10, thereby preventing debris from entering the lower cavity 104. After installation, the lower cavity 104 is substantially enclosed between the disk bottom surface 156, the cover inner surface 125, and the grip 10. The dimensions of the lower cavity 104 can further aid in providing an unobtrusive sensor housing 100.

[0053] The lower cavity 104 defines a depth measured vertically along the longitudinal axis 40 between the disk bottom surface 156 and the cover bottom end 122. In many embodiments, the lower cavity depth is between 0.005 inches and 0.10 inches. In some embodiments, the lower cavity depth is between 0.005 inches and 0.075 inches, 0.05 inches and 0.065 inches, or 0.075 inches and 0.10 inches. In some embodiments, the lower cavity depth is about 0.005 inches, 0.0075 inches, 0.010 inches, 0.0125 inches, 0.0150 inches, 0.0175 inches, 0.020 inches, 0.025 inches, 0.0275 inches, 0.030 inches, 0.0325 inches, 0.0350 inches, 0.0375 inches, 0.0400 inches, 0.0425 inches, 0.0450 inches, 0.0475 inches, 0.05 inches, 0.055 inches, 0.06 inches, 0.065 inches, 0.07 inches, 0.075 inches, 0.08 inches, 0.085 inches, 0.09 inches, 0.095 inches, or 0.10 inches. In an exemplary embodiment, the lower cavity depth is 0.06 inches. In some embodiments, the depth is substantially constant. In other embodiments, the base 150 has a variable thickness t D , the depth can be correspondingly variable. The depth of the lower cavity can be large enough so that the sensor housing 100 can be pressed firmly against the grip 10 such that at least a portion of the distal end 12 is retained within the lower cavity 104.

[0054] As mentioned above, the lower cavity 104 receives a portion of the grip 12, as illustrated in FIG. 1. The distal end 12 of the grip 10 defines a surface adjacent the bottom disk surface 156. A firm connection between the sensor housing 100 and the grip 10 causes a portion of the bottom disk surface 156 to contact said surface of the distal end 12. The contact between these adjacent surfaces can be characterized as the percentage of the total surface area of ​​the bottom disk surface 156 that contacts the surface of the distal end 12. In many embodiments, at least 25% of the bottom disk surface 156 contacts the surface of the distal end 12. In some embodiments, 25% to 35%, 30% to 50%, 45% to 65%, 50% to 75%, 60% to 85%, 70% to 95%, or 80% to 100% of the bottom disk surface 156 contacts the surface of the distal end 12. In some embodiments, at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100% of the disk bottom surface 156 is in contact with the surface of the endpiece 12. The amount of contact between these surfaces determines how flush the sensor housing 100 is against the grip endpiece 12. Thus, a higher percentage of contact is desirable to allow the sensor housing 100 to sit in a lower, more out of the way position. Additionally, a higher percentage of contact helps stabilize the sensor housing 100 since more of the surface area of ​​the disk 152 is supported by the surface of the endpiece 12.

[0055] As discussed above, the cover 120 provides a sheath for protecting and retaining the sensor 20 within the sensor cavity 102. With reference to Figures 12 and 13, the cover 120 may further include a number of ribs 130 (hereinafter referred to as "ribs") that retain the sensor 20 within the cavity. The ribs 130 protrude from the cover inner surface 125 into the sensor cavity 102 and contact the top surface of the sensor 20. The ribs 130 are located near the top end 121, i.e., near the rim 127.

[0056] In many embodiments, the ribs 130 have a shape, such as a rectangle or a trapezoid. For example, FIG. 13 illustrates one embodiment of the ribs 130, where the ribs 130 are substantially rectangular. In some embodiments, each rib 130 has the same shape as an adjacent rib 130, as illustrated in FIG. 13. In other embodiments, each rib 130 has a different shape than an adjacent rib 130. In many embodiments, the ribs 130 have a shape that corresponds to the shape of the sensor 20. For example, FIG. 1 illustrates a cross-sectional view of a sensor, where the sensor 20 has a variable diameter. In many embodiments, the ribs 130 are formed to prevent the sensor 20 from moving within the sensor cavity 102. The ribs 130 provide a lightweight mechanism for securing the sensor 20. Thus, the ribs 130 help provide an unobtrusive sensor housing 100 by not significantly increasing the structural mass of the sensor housing 100.

[0057] The cover 120 can have any suitable number of ribs 130 to properly secure the sensor 20 within the sensor cavity 102. For example, the cover 120 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 ribs. In some embodiments, the cover 120 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more ribs. In some embodiments, the ribs 130 are evenly spaced apart from one another. In other embodiments, the ribs 130 are not evenly spaced apart from one another. The ribs 130 are disposed around the periphery of the cover 120 near the top end 121 to secure the sensor 20 within the sensor cavity 102. Thus, the size, shape, and location of the ribs 130 are selected to ensure that the sensor 20 is securely secured within the sensor cavity 102. In some embodiments, the cover 120 can have additional features to assist in securely securing the sensor 20 within the sensor cavity 102.

[0058] In addition to the support provided by the ribs 130, the cover 120 has a variable inner diameter to further secure the sensor 20 within the sensor cavity 102. Referring to FIG. 14, the diameter of the cover varies from the top end 121 to the bottom end 122 to receive the base 150 while still securely securing the sensor 20. In many embodiments, the sensor 20 has a variable diameter. In these embodiments, the diameter of the cover 120 may vary to accommodate the sensor 20, as shown in FIG. 1. The diameter is smaller near the top opening 123 to hold the sensor 20 in place. The diameter gradually increases toward the bottom opening 124 until it is large enough to receive the base 150. The diameters described herein are measured in a plane perpendicular to the longitudinal axis 40.

[0059] Referring to FIG. 14, the top opening 123 has a top opening diameter D TO In many embodiments, the upper opening diameter D TO is between 0.50 inches and 0.75 inches. In some embodiments, the top opening diameter D TO is between 0.50 inches and 0.60 inches, between 0.55 inches and 0.75 inches, or between 0.65 inches and 0.70 inches. In some embodiments, the diameter D TO is about 0.50 inches, 0.51 inches, 0.52 inches, 0.53 inches, 0.54 inches, 0.55 inches, 0.56 inches, 0.57 inches, 0.58 inches, 0.59 inches, 0.60 inches, 0.61 inches, 0.62 inches, 0.63 inches, 0.64 inches, 0.65 inches, 0.66 inches, 0.67 inches, 0.68 inches, 0.69 inches, 0.70 inches, 0.71 inches, 0.72 inches, 0.73 inches, 0.74 inches, or 0.75 inches. In one exemplary embodiment, the top opening diameter D TO is 0.69 inches. Top opening diameter D TO is the minimum value for holding the sensor 20 in the sensor cavity 102.

[0060] Referring again to FIG. 14, the ribs 130 are spaced apart from each other by a rib diameter D measured through the center of the cover 120 between opposing ribs 130. R In many embodiments, the rib diameter D R In some embodiments, the rib diameter D R is between 0.50 inches and 0.60 inches, between 0.55 inches and 0.75 inches, or between 0.65 inches and 0.70 inches. In an exemplary embodiment, the rib diameter D R is 0.70 inches. In some embodiments, the rib diameter D R is about 0.50 inch, 0.51 inch, 0.52 inch, 0.53 inch, 0.54 inch, 0.55 inch, 0.56 inch, 0.57 inch, 0.58 inch, 0.59 inch, 0.60 inch, 0.61 inch, 0.62 inch, 0.63 inch, 0.64 inch, 0.65 inch, 0.66 inch, 0.67 inch, 0.68 inch, 0.69 inch, 0.70 inch, 0.71 inch, 0.72 inch, 0.73 inch, 0.74 inch, or 0.75 inch. R is the diameter D of the upper opening to accommodate the stepped shape of the sensor 20. TO Slightly smaller than

[0061] Referring again to FIG. 14, the sensor cavity 102 has a main cavity diameter D measured through the center of the cover 120 within the main or central portion of the sensor cavity 102. MC In many embodiments, the main cavity diameter D MC In some embodiments, the main cavity diameter D MC is between 0.70 inches and 0.80 inches, between 0.75 inches and 0.90 inches, or between 0.80 inches and 0.90 inches. In some embodiments, the rib diameter D Ris about 0.70 inches, 0.71 inches, 0.72 inches, 0.73 inches, 0.74 inches, 0.75 inches, 0.76 inches, 0.77 inches, 0.78 inches, 0.79 inches, 0.80 inches, 0.81 inches, 0.82 inches, 0.83 inches, 0.84 inches, 0.85 inches, 0.86 inches, 0.87 inches, 0.88 inches, 0.89 inches, or 0.90 inches. In one exemplary embodiment, the main cavity diameter D MC is 0.75 inches. Main cavity diameter D MC is the top opening diameter D to accommodate the widest portion of the sensor 20. TO and rib diameter D R can be larger than

[0062] Referring again to FIG. 14, the bottom opening 124 has a bottom opening diameter D BO In many embodiments, the bottom opening diameter D BO is between 0.70 inches and 0.90 inches. In some embodiments, the bottom opening diameter D BO is between 0.70 inches and 0.80 inches, between 0.75 inches and 0.90 inches, or between 0.80 inches and 0.90 inches. In some embodiments, the bottom opening diameter D BO is about 0.70 inches, 0.71 inches, 0.72 inches, 0.73 inches, 0.74 inches, 0.75 inches, 0.76 inches, 0.77 inches, 0.78 inches, 0.79 inches, 0.80 inches, 0.81 inches, 0.82 inches, 0.83 inches, 0.84 inches, 0.85 inches, 0.86 inches, 0.87 inches, 0.88 inches, 0.89 inches, or 0.90 inches. In one exemplary embodiment, the bottom opening diameter D BO In some embodiments, the diameter of the bottom opening D BO can vary depending on the presence of features near the bottom opening 124, such as thinned areas or notches. For example, FIG. 14 shows one embodiment of a cover 120 with a bottom opening diameter D BO is greater near the portion having the thinned region 129. In many embodiments, the bottom opening diameter D BOcorresponds to the diameter of the disk 152 so that the disk 152 can be received within the bottom opening 124.

[0063] The cover 120 further has an outer diameter measured from the outer surface 126 across the cover 120 (not shown). In many embodiments, the outer diameter is between 0.75 inches and 1.00 inches. In some embodiments, the outer diameter is between 0.75 inches and 0.90 inches, 0.85 inches and 0.90 inches, or 0.85 inches and 1.00 inches. In some embodiments, the outer diameter is about 0.75 inches, 0.76 inches, 0.77 inches, 0.78 inches, 0.79 inches, 0.80 inches, 0.81 inches, 0.82 inches, 0.83 inches, 0.84 inches, 0.85 inches, 0.86 inches, 0.87 inches, 0.88 inches, 0.89 inches, 0.90 inches, 0.91 inches, 0.92 inches, 0.93 inches, 0.94 inches, 0.95 inches, 0.96 inches, 0.97 inches, 0.98 inches, 0.99 inches, or 0.100 inches. In one exemplary embodiment, the outer diameter is 0.89 inches. This outer diameter is large enough to remain within the grip perimeter 17 while still providing the sensor housing 100 with sufficient thickness and durability. Additionally, all of the aforementioned diameters are small enough to ensure that the sensor housing 100 is small enough to remain within the grip perimeter 17.

[0064] The cover 120 further has a height (not shown) measured along the longitudinal axis 40 from the top end 121 to the bottom end 122. In many embodiments, the height is between 0.30 inches and 0.50 inches. In some embodiments, the height is between 0.30 inches and 0.45 inches, 0.35 inches and 0.50 inches, or 0.40 inches and 0.50 inches. In some embodiments, the height is about 0.30 inches, 0.31 inches, 0.32 inches, 0.33 inches, 0.34 inches, 0.35 inches, 0.36 inches, 0.37 inches, 0.38 inches, 0.39 inches, 0.40 inches, 0.41 inches, 0.42 inches, 0.33 inches, 0.44 inches, 0.45 inches, 0.46 inches, 0.47 inches, 0.48 inches, 0.49 inches, or 0.50 inches. In one exemplary embodiment, the height is 0.48 inches. The height can be selected to accommodate the sensor 20 .

[0065] The cover 120 further has a thickness measured from the inner surface 125 to the outer surface 126. In many embodiments, the thickness is between 0.01 inches and 0.25 inches. In some embodiments, the thickness is between 0.01 inches and 0.15 inches, 0.10 inches and 0.20 inches, or 0.15 inches and 0.25 inches. In some embodiments, the thickness is about 0.010 inches, 0.015 inches, 0.020 inches, 0.025 inches, 0.030 inches, 0.035 inches, 0.040 inches, 0.045 inches, 0.050 inches, 0.055 inches, 0.060 inches, 0.065 inches, 0.070 inches, 0.075 inches, 0.080 inches, 0.085 inches, 0.090 inches, 0.095 inches, 0.10 inches, 0.11 inches, 0.12 inches, 0.13 inches, 0.14 inches, 0.15 inches, 0.16 inches, 0.17 inches, 0.18 inches, 0.19 inches, 0.20 inches, 0.21 inches, 0.22 inches, 0.23 inches, 0.24 inches, or 0.25 inches. This thickness is large enough to remain within grip perimeter 17 while still providing sufficient durability to sensor housing 100 .

[0066] As discussed above, the cover 120 provides several functions to the sensor housing 100. That is, the cover 120 provides a sheath for the sensor 20 and also provides a structure for receiving the base 150. The various features of the cover 120 can be configured to provide an unobtrusive sensor housing 100. For example, in some embodiments, the presence of the windows 128 or ribs 130 can reduce the structural mass of the sensor housing 100, thereby preventing the sensor housing 100 from significantly affecting the center of gravity of the golf club.

[0067] As discussed above, various features of the sensor housing 100 can be designed to provide a lightweight sensor housing. In many embodiments, the sensor housing 100 has a mass between 5.0 grams and 7.0 grams.

Sensor housing 200 includes a base 250 and a cover 220 that utilize a different mating mechanism than sensor housing 100. Cover 220 does not include a window and base does not include tabs. Instead, cover 220 has a two-piece construction that includes a rim 270 and a skirt 280. Rather than utilizing the window and tab system of sensor housing 100, rim 270 secures the components together as described in more detail below.

[0070] 18, base 250 includes a disk 252 and a post 260, the post being similar to post 160 described above. In comparison to disk 152, disk 252 does not have tabs. Instead, base 250 defines a plurality of recessed portions 290, with disk periphery 257 recessed inwardly toward the center of disk 252. As will be described in more detail below, recessed portions 290 serve to facilitate connection between base 250 and cover 220 by receiving a plurality of notches 286 disposed on cover 220.

[0071] In many embodiments, the recessed portions 290 have a shape such as a rectangle or trapezoid in cross-section or side view. For example, FIG. 18 illustrates one embodiment of recessed portions 290, where recessed portions 290 define a rectangular shape. Recessed portions 290 can be configured to allow notches 286 to slide into place when received in cover 220. In some embodiments, as illustrated in FIG. 18, each recessed portion 290 has the same shape as recessed portions 290. In other embodiments, recessed portions 290 have a different shape than recessed portions 290. In many embodiments, recessed portions 290 can have a similar shape to the shape of the corresponding notches 286, such that recessed portions 290 receive notches 286.

[0072] The disk 252 can have any suitable number of recessed portions 290 to allow the cover 220 to be secured to the base 250. For example, the disk 252 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 recessed portions. In some embodiments, the disk 252 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more recessed portions. In some embodiments, the recessed portions 290 are equally spaced apart from one another. In other embodiments, the recessed portions 290 are not equally spaced apart from one another. The recessed portions 290 are disposed about the disk periphery 257 to allow the disk 252 (and base 250) to be received by the cover 220. Thus, the size, shape, and location of the recessed portions 290 are selected such that the notches 286 of the cover 220 can be securely secured within the recessed portions 290. In some embodiments, the shape and dimensions of the recessed portion 290 modify the dimensions of the disk 252 .

[0073] As noted above, base 250 is similar to base 150. Disk 252 is similar to disk 152 except that it does not have tab 158. Disk 252 has a diameter similar to that of disk 152 and a thickness tD Same thickness t D Additionally, post 260 is similar to post 160. Post 260 has a first post offset O similar to that of post 160. P1 and / or the second post-offset O P2 In some embodiments, the screw 262 includes a thickened section 264 similar to that of the post 160. As with the sensor housing 100, the sensor housing 200 minimizes the structural weight of each feature, which helps provide an unobtrusive sensor housing that does not significantly impact the center of gravity of the golf club. The cover 220 provides a sheath for the upper portion of the sensor 20, while the base 250 supports the lower portion of the sensor 20.

[0074] 16 and 17, the cover 220 is substantially similar in shape to the cover 120. However, the cover 220 has a two-piece construction including a rim 270 and a skirt 280. The skirt 280 is the peripheral portion of the cover 220, and the rim is the top portion of the cover 220. The skirt 280 can have a number of notches 286 that correspond to the recessed portions 290 located on the base 250. To assemble the sensor housing 200, the base 250 can first be placed into the skirt 280, then the sensor can be placed into the sensor cavity 202, and finally the rim 270 can be secured onto the sensor 20 and clipped onto the skirt 280.

[0075] The skirt 280 provides a mechanism for receiving the base 250 as well as the rim 270. Referring again to FIG. 17, the skirt 280 may have a number of notches 286 near the bottom end 222. The notches 286 may facilitate interaction between the cover 120 and the base 150 by providing support areas that correspond to recessed portions 290 located on the base 250. A strong, non-removable connection is then formed between the notches 286 and the recessed portions 290. The notches 286 are sized and positioned to correspond to the recessed portions 290 to facilitate the connection therebetween.

[0076] The skirt 280 can have any suitable number of notches 286 to allow the skirt 280 to receive the base 250. For example, the skirt 280 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 notches. In some embodiments, the skirt 280 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more notches. In some embodiments, the notches 286 are equally spaced from one another. In other embodiments, the notches 286 are not equally spaced from one another. The notches 286 are disposed about the periphery of the skirt 280 near the bottom end 222 to allow the base 250 to be received in the skirt 280. Thus, the size, shape, and location of the notches 286 are selected to allow the recessed portion 290 to be securely secured within the notches 286.

[0077] 17, the skirt 280 can define a circumferential recess 284 near the top end 221. The recess 284 can receive a protrusion 274 located on the rim 270 to secure the rim 270 to the skirt 280. FIG. 17 illustrates an embodiment in which the sensor housing 200 has a single continuous recess 284. However, in other embodiments, the sensor housing 200 can have multiple separate recesses 284 that correspond to features located on the rim 270. In many embodiments, the recess 284 is formed to prevent the rim 270 from being removed from the skirt 280. In many embodiments, the recess 284 can have a similar shape to the protrusion 274 such that the recess 284 can receive the protrusion 274.

[0078] The skirt 280 can have any suitable number of recesses 284 to allow the skirt 280 to be secured to the rim 270. For example, the skirt 280 can have 2 to 4, 3 to 6, 4 to 8, or 5 to 10 recesses. In some embodiments, the skirt 280 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more recesses. In some embodiments, the recesses 284 are equally spaced apart from one another. In other embodiments, the recesses 284 are not equally spaced apart from one another. The recesses 284 are disposed about the periphery of the skirt 280 near the top end 221 such that the rim 270 is received by the skirt 280. Thus, the size, shape, and location of the recesses 284 are selected to allow the projections 274 to be securely secured within the recesses 284. As discussed above, the skirt 280 provides a means for receiving both the base 250 and the rim 270.

[0079] 16 and 17, a rim 270 defines an upper portion of the cover 220. The rim 270 can be clipped into a skirt 280 to secure the sensor in the sensor cavity 202. In many embodiments, the skirt 280 can have a circumferential projection 274 to secure the rim 270 to the skirt 280. FIG. 17 illustrates an embodiment in which the rim 270 has a single continuous projection 274. However, in other embodiments, the rim 270 can have a plurality of separate projections 274 that correspond to a plurality of recesses 284 located on the skirt 280. In many embodiments, the projection 274 can have a similar shape as the recess 284 such that the recess 284 can receive the projection 274.

[0080] The rim 270 can have any suitable number of projections 274 to enable the skirt 280 to be secured to the rim 270. For example, the rim 270 can have 2 to 4 projections, 3 to 6 projections, 4 to 8 projections, or 5 to 10 projections. In some embodiments, the skirt 280 can have 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 or more projections. In some embodiments, the projections 274 are equally spaced from one another. In other embodiments, the projections 274 are not equally spaced from one another. The projections 274 are positioned around the rim 270 such that the rim 270 is received by the skirt 280. Thus, the size, shape, and location of the projections 274 are selected to enable the projections 274 to be securely secured within the recesses 284.

[0081] As discussed above, sensor housing 100 is enclosed via the tab and window system previously described. However, sensor housing 200 is enclosed via a connection between a rim 270 and a skirt 280. However, sensor housing 200 is similar to sensor housing 100, only the coupling mechanism is different. Specifically, the general shape, dimensions, and materials of sensor housing 200 are similar to those of sensor housing 100.

[0082] The sensor housing described herein provides advantages that are improvements over the prior art. The sensor housing is unobtrusive and easy to manufacture. The sensor housing has features that stay within the grip footprint and reduce mass, reducing the length added to the grip. As such, the sensor housing minimizes the impact on CG. The sensor housing can be used on grips that have asymmetric shapes. The sensor housing provides a secure structure for the sensor. The sensor housing also provides manufacturing advantages. The sensor housing can be formed from multiple materials and does not require adhesives to secure the sensor. The lack of adhesives further reduces the structural weight of the sensor housing. The sensor housing is versatile and can be used on a variety of sporting goods such as golf clubs, bats, and racquets.

[0083] (method) The method of manufacturing a golf club described herein includes the steps of (1) providing a grip, (2) forming an opening in the grip, (3) forming a cover, (4) forming a base, (5) providing a sensor, (6) placing the cover over the sensor, (7) coupling the base to the cover, and (8) coupling the sensor housing to the grip. In step 2, the opening can be a threaded opening formed in the distal end of the grip. The opening can be located at an offset location as described above. In step 3, the cover can have a one-piece or two-piece construction. The cover can have various features for coupling with corresponding features located on the base. For example, the cover can have multiple windows or multiple protrusions. In step 4, the base can include a disk and an integrally formed post extending from a bottom surface of the disk. The base can have various features for coupling with corresponding features located on the cover. For example, the base can include multiple tabs or recessed portions. In step 7, the base can be received through a lower opening of the cover or inserted through an upper opening of the cover. In some embodiments, the cover and base can be coupled via a plurality of corresponding tabs and windows. In step 8, the threaded post is received within the opening. Additionally, the sensor housing is received in the grip such that the sensor housing is disposed within the grip perimeter.

[0084] (example) Further described herein are comparisons of performance results between multiple sensor housings having various configurations. The results compare the impact of sensor housing size and shape on user satisfaction. Dimensions, weight, and location were varied across sample sensor housings. As discussed above, these variables can determine how noticeable or awkward a sensor housing is to a user.

[0085] The control sensor housing had a three-piece configuration including a cover with a skirt and a rim, and a base. The cover and base were joined via a number of interlocking features. The sensor was secured between the cover and base using an adhesive. The base included a disk and a post, with the post located at the center of the disk. The positioning of the post could cause the control sensor housing to protrude or extend beyond the perimeter of the grip. The lower cavity defined a depth of 0.16 inches. The control sensor housing had a height of 0.55 inches, an outer diameter of 1.10 inches, and a weight of 7.8 grams.

[0086] The exemplary sensor housing was designed as an unobtrusive sensor housing similar to the sensor housing 100 shown in FIGS. 3-6. The exemplary sensor housing had a two-piece shape including a cover and a base. The cover and base were joined via a number of corresponding tabs and windows. The sensor was secured between the cover and base without the use of adhesives. The base included a disk and a post, with the post offset forward relative to the center of the disk. This offset allowed the sensor housing to remain within the grip perimeter. Additionally, the post included multiple thickened areas to more securely secure the post within the grip opening. The lower cavity defined a depth of 0.06 inches such that at least 50% of the bottom surface of the disk was in contact with the surface of the grip. The exemplary sensor housing had a height of 0.48 inches, an outer diameter of 0.89 inches, and a weight of 6.2 grams.

[0087] The performance test measured overall user satisfaction with the sample sensor housings. Twenty-two users were asked to compare the sensor housings and rate the overall intrusiveness of each sensor housing. The level of intrusiveness was determined by several factors, including the height of the sensor housing, the amount it protruded beyond the grip perimeter, and the feel of the sensor housing in the user's hand. The exemplary sensor housings demonstrated performance advantages over the control sensor housings, as described in more detail below.

[0088] The exemplary sensor housing demonstrated improved user satisfaction over the control sensor housing. Specifically, 75% of users indicated they preferred the exemplary sensor housing over the control sensor housing. A comparison between the two sensor housings illustrated the impact that size and positioning have in creating a less intrusive sensor housing. The improved performance of the exemplary sensor housing is due to its smaller size and careful positioning within the grip perimeter.

[0089] The exemplary sensor housing was designed as a lightweight alternative to the control sensor housing. To reduce mass, the exemplary sensor housing was substantially smaller than the control sensor housing and did not utilize adhesives. The exemplary sensor housing was 14% shorter, 18% narrower, and 21% lighter than the control sensor housing. The height of the sensor housing determined how much the sensor housing protruded from the end of the grip. Additionally, the diameter and amount of protrusion of the sensor housing determined how much the user would notice the sensor housing near the grip perimeter. Additionally, the exemplary sensor housing included an offset post, which positioned the sensor housing within the perimeter of the grip. As a result, the difference in size and shape of the exemplary sensor housing provided a less obtrusive sensor housing that is preferred by most users.
