As shown in Figures 2 and 3, after the sliding mechanism 22/100/200 has been completely assembled and connected to the distal and proximal portions 12 and 14 of the instrument 10, the sliding mechanism 22/100/200 allows The lower end of the distal portion 12 of the instrument undergoes restricted, low-friction lateral / lateral movement relative to the upper end of the proximal portion 14 of the instrument, while having strong mechanical integrity. In other words, the track guide block 24/102/202 of the sliding mechanism 22/100/200, a plurality of front ball bearings (eg, front ball bearings 26 and 28), and a plurality of rear ball bearings (eg, rear ball bearings 30 and 32) and the slide assembly 104/204 cooperate to allow low friction lateral / lateral movement of the lower end of the distal portion 12 relative to the upper end of the proximal portion 14 during the swing 16 of the instrument 10 (eg, a Lateral / lateral offset), where the movement / movement / offset is limited to directions orthogonal to both the longitudinal axis Y1 of the lower end and the longitudinal axis Y2 of the upper end, and the movement / movement / offset is limited to the maximum orbit Move within D1.

1.1 Application of golf clubs

The training device embodiments described in this section are hereinafter referred to as golf club related embodiments. These golf club related embodiments are generally related to the field of golf clubs, and in particular to a golf club swing training device, which golfers can use to increase their power to swing the golf club (for example, to make their swings familiar), thereby becoming More excellent golfers. It should be understood that in the field of golf, golfers can use Gower The natural flexibility of the golf club shaft forms a trajectory that correctly hits the golf ball, causing the ball to bend selectively from left to right or from right to left. As will be described in more detail below, these golf club related embodiments can teach golfers to utilize the momentum of the club head when swinging the golf club to achieve the desired ball trajectory shape. In other words, these golf club related embodiments are specifically designed to help golfers learn to selectively control the trajectory shape of the golf ball, so that the ball can be "curved" from right to left or from left to right in a controlled manner.

Referring again to FIGS. 1 to 7, the sports equipment 10 in the golf club related embodiment described in this section is a conventional golf club shaft with one end and one end, and the object 18 is a conventional golf ball, The distal portion 12 of the instrument is a lower shaft portion including the head end of the shaft, the proximal portion 14 of the instrument is an upper shaft portion including the root end or handle of the shaft, and the sliding mechanism 22 is a cavity sliding mechanism 100. Such golf club related embodiments benefit from a variety of reasons, including but not limited to the following. These golf club related embodiments can be used with any type of golf club (eg, tee, and other types of golf clubs). These golf club related embodiments are equally applicable to swinging 16 right-handed golf clubs from right to left, and swinging 16 left-handed golf clubs from left to right.

Referring again to FIG. 7, and as will be described in more detail regarding the related embodiments of the golf clubs after the cavity sliding mechanism 100 has been completely assembled and inserted between the lower shaft portion and the upper shaft portion , Golfers successfully use these golf clubs related embodiments During the period (ie, during correct / appropriate swinging of the golf club to achieve the desired shape of the ball trajectory), the aforementioned lateral / lateral movement of the upper end of the lower shaft portion relative to the lower end of the upper shaft portion can occur / Sport / offset, so that the sliding mechanism 100 provides auditory and tactile feedback to the golfer, indicating whether it has reached the desired swing contour. In particular, when the golfer swings his club so that the upper end of the lower shaft portion is moved laterally / laterally / moved / offset relative to the lower end of the upper shaft portion, the head of the club faces the ball, After being hit by a distance greater than or equal to the aforementioned maximum track movement distance D1, when the head surface is perpendicular to the ball impact direction, a ball trajectory shape is generated from right to left. On the other hand, when the golfer swings his club to prevent the movement / movement / offset, the upper end of the lower shaft portion remains coaxial with respect to the lower end of the upper shaft portion, and the head is on the shaft axis When the back strikes the ball, making the head surface perpendicular to the direction of the ball's impact, a trajectory of the ball from left to right is produced. Therefore, by practicing with the golf club related embodiments described in this section, golfers will learn how to control and change their swing patterns to produce the desired right-to-left or left-to-right ball trajectory shape. When the movement / movement / offset occurs, auditory and tactile feedback will be generated for the golfer, so that the golfer knows whether the movement / movement / offset and its occurrence time occur during his swing, so that the golfer By changing the amount of swing power, the movement / movement / offset is generated or prevented to achieve the desired ball trajectory shape.

The lower part of the slide rail part 106 includes a slide rail block 122, wherein the bottom of the connector 118 is firmly connected to the center position of the top surface 124 of the slide rail block 122 so that the cavity 120 and the slide rail block 122 share The longitudinal axis Y3 is orthogonal to the surface 124, thus ensuring that when the upper end is connected to the top of the connector 118, the longitudinal axis of the upper end of the lower shaft portion is orthogonal to the surface 124.

As shown in FIGS. 12 to 15, and referring again to FIG. 7, the lower portion of the cavity-shaped rail guide block 102 includes a lower connector 128, which is adapted to allow the lower end of the upper shaft portion to be firmly connected to the The bottom end 152 of the connector 128 is connected in such a manner that the lower end is coaxial with the connector 128, and regardless of swinging the club, it is coaxial with the track guide block 102. It should be noted that this fastening connection can be realized in various ways. As an example but not limited, the cavity track guide block shown in Figures 12 to 15 In the 102 embodiment, this adaptation is configured in the following manner. The bottom end 152 of the lower connector 128 includes a cylindrical cavity 130 that is coaxial with the connector 128. The diameter D4 of the cavity 130 is adjusted to allow the lower end of the upper shaft portion to be snugly inserted into the cavity 130, while using the aforementioned strong adhesive to securely bond the radially outer surface of the lower end To the radial wall of the cavity 130. It should be noted that the diameter D4 is generally slightly larger than the diameter D3, because for a conventional golf club shaft, the diameter of the lower end of the upper shaft portion is generally slightly larger than the diameter of the upper end of the lower shaft portion. The upper part of the rail guide block 102 includes a guide pad 132, wherein the top of the connector 128 is firmly connected to the center position of the bottom surface 134 of the guide pad 132, so that the cavity 130 and the guide pad 132 The common longitudinal axis Y4 of is orthogonal to the surface 134, thus ensuring that when the lower end is connected to the bottom 152 of the connector 128, the longitudinal axis of the lower end of the upper shaft portion is orthogonal to the surface 134.

In general, and referring again to FIGS. 4 and 7-15, the cavity track guide block 102, the front ball bearing 26/28, the rear ball bearing 30/32, and the cavity slide assembly 104 cooperate to allow the assembly 104 A low-friction lateral / lateral movement (eg, a lateral / lateral offset) occurs with respect to the track guide block 102, and the movement / offset is limited to the maximum track movement distance D1. In particular, the slide rail block 122 of the cavity slide rail part 106 has a predetermined width W1 and includes a pair of opposed extended rail slots 136 and 138 (ie, a front rail slot 136 and a rear rail slot 138). As shown in FIGS. 4 and 10, the positioning of the rail slots 136 and 138 ensures that the horizontal plane of the longitudinal axis and the longitudinal axis of the slide rail part 106 Y3 is orthogonal. The upper portion of the guide pad 132 of the cavity track guide block 102 includes a linear guide channel 140, which passes through the left side 146 of the guide pad 132 to the right side 148. The channel 140 is usually adapted to be received in sliding contact The combination of the slide rail block 122 and the front and rear ball bearings 26/28/30/32 (when the combination slides into the channel 140). In particular, the vertical axis of the linear guide channel 140 is aligned with the common longitudinal axis Y4 of the aforementioned rail guide block 102. The guide channel 140 has parallel vertical side walls and a pair of opposed extended guide slots 142 and 144 (ie, a front guide slot 142 and a rear guide slot 144), wherein the front guide slot 142 is located in the channel On one side wall of 140, the rear guide slot 144 is located on the other side wall of the channel 140. As shown in FIGS. 4 and 14, the front and rear guide slots 142 and 144 are located on the respective side walls so that the horizontal plane of the longitudinal axis is orthogonal to the longitudinal axis Y4. The guide channel 140 also has a preset width W2, which is slightly larger than the width W1, thus allowing the slide rail block 122 to move and position within the channel 140. The front rail slot 136 and the front guide slot 142 have a common shape, and are slightly smaller than a half turn, which is sized to allow the slots 136 and 142 to receive the front ball bearings 26/28 (when (When the slide rail block 122 is located in the guide channel 140). The front ball bearings 26/28 are therefore used to slightly separate the front rail slot 136 from the front guide slot 142. In an exemplary embodiment of the cavity-type sliding mechanism 100, the size and shape of the front rail slot 136 and the front guide slot 142 match the size and shape of a part of the outer surface of the front ball bearing 26/28, so Each contact between the ball bearings 26/28 and the slots 136 and 142 will be equally distributed among the ball bearings The entire surface of 26/28 to minimize the friction between these slots and ball bearings. Similarly, the rear track slot 138 and the rear guide slot 144 have a common shape and are slightly smaller than a half turn, which is sized to allow the slots 138 and 144 to receive the rear ball bearing 30 / in a low-friction rolling contact manner 32 (when the slide rail block 122 is located in the guide channel 140). The rear ball bearing 30/32 is therefore used to slightly separate the rear rail slot 138 from the rear guide slot 144. In an exemplary embodiment of the sliding mechanism 100, the size and shape of the rear rail slot 138 and the rear guide slot 144 coincide with the size and shape of a part of the outer surface of the rear ball bearing 30/32, so each ball Each contact between the bearings 30/32 and the slots 138 and 144 will be equally distributed over the entire surface of each ball bearing 30/32, thereby minimizing the friction between these slots and the ball bearings. Therefore, when the slide rail block 122 has been moved and positioned in the guide channel 140, the front ball bearing 26/28 has rotated and slidably inserted into the front rail slot 136 and the front guide slot 142, and the rear ball bearing 30/32 has After rotating and slidingly inserting into the rear rail slot 138 and the rear guide slot 144, the rail part 106 (and the rail assembly 104) can be allowed to be aligned with the longitudinal axis Y3 of the rail part 106 (and the longitudinal axis of the rail assembly 104 ) Sliding / moving in a direction orthogonal to the longitudinal axis Y4 of the rail guide block 102.

Referring again to Figures 4, 7, 9, 10, 13 and 14, in an exemplary implementation of the cavity slide mechanism 100, the difference between the above widths W1 and W2 is greater than or equal to 1.0 mm and less than or It is equal to 2.0 mm. The cavity slide part 106 may optionally include one or more weight-reducing orifices (not shown) for further reducing the weight of the cavity slide mechanism 100. (Shown), without negatively affecting the structural integrity of the rail member 106, the size of the orifices is set to be as large as possible. Similarly, the cavity track guide block 102 can optionally include one or more weight reduction orifices (also not shown) for further reducing the weight of the sliding mechanism 100, without negatively affecting the track guide block 102's Under structural integrity, the size of the orifices is set to be as large as possible. The outer edges and corners of the sliding mechanism 100 can be selectively rounded to avoid injury to the golfer and further reduce the weight of the sliding mechanism 100.

As shown in FIGS. 5, 6 and 12 to 15, the guide pad 132 of the cavity track guide block 102 further includes a track travel distance limitation on the bottom surface 156 of the guide channel 140 of the track guide block孔口 154. It should be noted that the orbital movement distance limiting aperture 154 represents an embodiment of the aforementioned orbital movement distance limiting structure 40. The orbital movement distance limiting orifice 154 has a predetermined width W3 and a predetermined length L2, and in an exemplary embodiment of the rail guide block 102, it passes through the cylindrical cavity 130 and the linear guide channel 140 between. As shown in FIGS. 8 to 11, the cavity slide member 106 includes a longitudinal aperture 126 that passes through the cylindrical cavity 120 to reach the bottom 158 of the slide member 106 (which is the bottom of the slide block 122 ), Wherein the longitudinal axis of the orifice 126 is aligned with the common longitudinal axis Y3 of the cavity 120 and the rail pad 122. In other words, the aperture 126 is coaxial with the upper connector 118 and the slide rail block 122. The orifice 126 has a preset radial cross-sectional shape and a preset diameter D5. As shown in FIG. 7, the cavity-type sliding restricting part 108 that is fastened into the opening 126 includes an opening-fitting post 160 (representing an embodiment of the aforementioned post 36) and A head 162 firmly connected to the top of the post 160. The post 160 has the same radial cross-sectional shape as the radial cross-sectional shape of the orifice 126. The post 160 also has a preset length L3 and a preset diameter D2, which are selected to allow the post 160 to be fully and firmly inserted down into the aperture 126, so after this insertion, the post 160 is made of the slide rail part 106 The bottom 158 of the protrusion (a part of the protrusion is shown in FIG. 4), and the bottom of the post 160 moves toward the track to the protrusion restriction distance 154 protruding the aforementioned protrusion distance.

Referring again to FIGS. 7-11, in one implementation of the cavity-type sliding mechanism 100, the longitudinal aperture 126 may have a circular radial cross-sectional shape and may be threaded, and the aperture may also fit the radial outer surface of the post 160 Threads are formed to allow the post 160 to be screw-connected with the aperture 126, and the cavity slide restricting part 108 is tightly inserted into the cavity slide part 106 by completely screwing the post 160 into the aperture 126. In this particular implementation, a lock washer (not shown) can be selectively connected to the post 160 before it is screwed into the hole 126; when the post 160 is completely screwed into the hole 126, the lock washer will be clamped to the head Between the bottom of the portion 162 and the bottom of the cylindrical cavity 120. In another implementation of the sliding mechanism 100, the orifice 126 is not threaded, and the radial outer surface of the post 160 is not threaded, and the orifice 126 may have any radial cross-sectional shape (eg, round, square, and six) Sides, and other two-dimensional shapes), by inserting the post 160 into the aperture 126 (using the aforementioned strong adhesive to secure the radially outer surface of the adhesive post 160 to the radial wall of the aperture 126), the sliding restricting part 108 Fasten the slide rail part 106.

Referring again to FIGS. 2 to 15, the ball bearing retainer structure 38 is usually adapted so that when the slide block 122 of the cavity slide part 106 is moved and positioned within the guide channel 140 of the cavity guide block 102 , The front ball bearing 26/28 is held between the front rail slot 136 and the front guide slot 142, and the rear ball bearing 30/32 is held between the rear track slot 138 and the rear guide slot 144. It should be noted that the ball bearing retainer structure 38 can be implemented in a variety of ways. As an example, but not limited, as in the embodiments of the cavity slide assembly 104 shown in FIGS. 2 to 4 and 7 to 10, the ball bearing retainer structure 38 is implemented in the following manner. The ball bearing retainer structure includes the aforementioned front ball bearing retainer parts 110 and 114, and the rear ball bearing retainer parts 112 and 116. The retainer parts 110/112/114/116 include a post (e.g., post 164) and a head (e.g., head 166) secured to one end of the post. The slide rail block 122 includes a pair of front retainer part cavities 168 and 170 and a pair of rear retainer part cavities 172 and 174, wherein each longitudinal axis of the cavities 168/170/172/174 is located in the aforementioned track insert The horizontal planes on which the grooves 136 and 138 are positioned (as shown in Figures 8 and 10), and the respective sizes and shapes of the cavities 168/170/172/174 are adjusted to allow the retainer part 110/112 / A specific post of 114/116 (e.g. post 164) is fully and securely inserted into the cavity so that the head of the retainer part (e.g. head 166) and the left side 184 or right side 186 of the slide rail block 122 Contact (as shown in Figures 2 to 4). In an implementation of the slide rail assembly 104, the cavities 168/170/172/174 all have a circular radial cross-sectional shape and can be formed with threads, and each retainer part The radial outer surface of the column 110/112/114/116 can also be threaded, allowing it to be screwed into a specific cavity in the cavity 168/170/172/174. As shown in Figures 3 and 4, the head of each retainer part 110/112/114/116 is selected, and its radial size allows the head to cover a specific end of one of the rail slots 136/138 A portion is provided, where the portion is large enough to prevent the ball bearings 26/28/30/32 from falling off the sliding mechanism 100 (when it is fully assembled, swing the golf club anyway), and small enough to allow the assembly 104 to guide relative to the track The aforementioned lateral / lateral movement of the lead block 102 (eg, the front ball bearing retainer parts 110 and 114 hold the front ball bearing 26/28 between the front rail slot 136 and the front rail slot 142, and the rear ball bearing retainer Parts 112 and 116 hold the rear ball bearing 30/32 between the rear rail slot 138 and the rear rail slot 144).

As shown in FIGS. 4 to 6, this section explains the functional operation of the cavity sliding mechanism 100, and referring again to FIGS. 7 to 15, after the cavity sliding mechanism 100 has been completely assembled, the cavity sliding restricts the hole of the part 108 The length L3 of the mouth matching post 160 is selected so that the bottom of the post 160 moves toward the track on the cavity track guide block 102 to limit the protrusion distance in the orifice 154 by the aforementioned protrusion distance. As will be described in more detail now, the orifice 154 is adapted to limit the movement of the cavity slide assembly 104 (eg, to limit the aforementioned lateral / lateral movement / movement / offset) to the maximum orbital movement distance D1 (through the column The movement limit of 160 is the distance D1). In particular, the aperture 154 has a pair of opposed vertical side walls 176 and 178 that are parallel to each other and parallel to the vertical side walls of the linear guide channel 140 of the track guide block. Orifice 154 has another pair of opposed vertical side walls 180 and 182, which are symmetrical to each other, wherein the horizontal center portions of both side walls 180 and 182 are orthogonal to the sliding / moving direction of the cavity slide member 106, and therefore also to the slide restricting member 108 The sliding / moving direction of the column 160 is orthogonal. As shown in FIGS. 5 and 6, the width W3 and the length L2 of the orifice 154 are both larger than the diameter D2 of the column 160, thus allowing the column 160 to move inside the orifice 154 (eg, from the second, third, fifth, and (The angle of view of Figure 6 is left and right). As shown in Figures 5 and 6, the difference between the length L2 and the diameter D2 determines the distance D1. When the slide rail assembly 104 is located at the coaxial position of the aforementioned track guide block 102, the right side of the post 160 is in contact with the side wall 182, as shown in FIG. When the slide rail assembly 104 is located at the maximum non-coaxial position of the rail guide block 102 (the leftmost position in the illustrated example), the left side of the column 160 contacts the side wall 180, as shown in FIG. 6. In general, the length L2 and the diameter D2 can be selected so that the distance D1 can have any value, where the value is selected based on the rigidity of the golf club (compared to other factors). By way of example but not limitation, in one exemplary embodiment of the sliding mechanism 100, the length L2 and the diameter D2 are selected so that the distance D1 is approximately 0.65 mm.

In view of the above, and referring again to FIGS. 5 to 7, it should be understood that the cavity sliding mechanism 100 allows a golfer to hear and feel the upper end of the lower shaft portion relative to the upper shaft portion when swinging the club in a desired manner Lateral / lateral movement / movement / offset at the lower end. In other words, when the sliding mechanism 100 is inserted into the club shaft as described herein, the sliding mechanism 100 can provide the aforementioned auditory and tactile feedback to the golfer, indicating whether it has reached the desired swing contour. For example, when swinging the ball When the upper end of the lower shaft portion is moved laterally / laterally to the left with respect to the lower end of the upper shaft portion, the cavity slide assembly 104 can achieve the maximum degree of non- In a coaxial position, and the left side of the orifice cooperating column 160 will hit the vertical side wall 180 of the orbital movement distance limiting orifice 154, the sliding mechanism 100 can produce a recognizable sound (for example, a golfer will hear a "click" sound), At the same time, a tactile sensation will be generated at the proximal end of the club (for example, the golfer will feel the vibration from the sliding mechanism 100 traveling through the upper shaft portion into his hand).

It should also be understood that the cavity slide mechanism can be inserted into the golf club shaft anywhere along the shaft. Various factors need to be considered for the aforementioned position determination along the shaft and the insertion of the sliding mechanism, such as the following. A handle that brings the sliding mechanism closer to the root end of the shaft allows the shaft to bend as much as possible during swing, which is an advantageous factor. However, the inherent weight of the sliding mechanism can also change the balance point of the shaft, which is an unfavorable factor, wherein the degree of the change depends on the actual weight of the sliding mechanism and the specific position of the sliding mechanism inserted along the shaft. In an exemplary implementation of the golf club described in this section, the golf club is a tee, has a carbon fiber shaft, and has an overall length of approximately 45 inches. The gap between the aforementioned sliding mechanism insertion and the shaft root The distance between the ends is about 30% of the total length of the rod (including the head of the rod).

The training device embodiments described in this section are hereinafter referred to as baseball bat related embodiments. The related embodiments of these baseball bats generally relate to the field of baseball bats, and in particular to a baseball bat swing training device, which can be used by a batter to increase his own strength to swing the bat (for example, to make him skilled in swinging bats). Become a better hitter (eg, increase his swing speed and hitting frequency). In other words, and as will be described in more detail below, these baseball bat-related embodiments can teach the batter to swing the bat faster (eg, to increase his swing speed and strength), thereby ensuring that the batter can handle more difficult The ball hits the ball more stably.

Referring again to FIGS. 1 to 6 and 16, the sports equipment 10 in the related embodiment of the baseball bat described in this section is a conventional baseball bat, the object 18 is a conventional baseball, and the distal portion 12 of the equipment is the The barrel portion of the bat, the proximal portion 14 of the instrument is the handle portion of the bat, and the sliding mechanism 22 is a cylindrical sliding mechanism 200. Such baseball bat-related embodiments benefit from a variety of reasons, including but not limited to the following. Such baseball bat-related embodiments may use any type of baseball bat, including but not limited to conventional wooden bats, or conventional metal bats, or conventional composite bats, or conventional hybrid bats. It should be understood that in baseball, wooden bats are more resilient than metal rods, and are generally more resilient than composite and hybrid rods. A batter with a better swing strength can cause the stick to bend when swinging. This bending usually occurs between the proximal and distal ends of the bat, and will further increase the speed / force of the barrel portion. In view of the above, it should be understood that when the sliding mechanism 200 is inserted into a metal rod, or a composite rod, or a hybrid rod, the sliding mechanism 200 may allow the metal / composite / hybrid rod to simulate a wooden rod.

The advantage of this auditory and tactile feedback is that it can realistically simulate the impact of a bat on a baseball. Therefore, by practicing the related embodiments of the baseball bat described in this section, the batter can learn how to increase the speed and strength of his bat swing.

In addition, it should be understood that in baseball, hitters usually warm up shortly before entering the hitting area. The hitter can perform this warm-up in a variety of ways, including the following. A hitter can warm up by swinging a baseball bat that is significantly heavier than the bat he will use in the hitting area. A hitter can also warm up by swinging a set of compound bats heavier than the bats he will use in the hitting area. The hitter can also put a conventional weight ring on his bat, and then warm up by swinging the temporarily increased bat. A further advantage of the related embodiment of the baseball bat described in this section is that it can be used as a warm-up device for batters. In particular, in an exemplary warm-up implementation of the related embodiments of these baseball bats, the hitter can insert the conventional weight ring after the cylindrical sliding mechanism has been completely assembled and inserted between the barrel of the bat and the handle portion Put on the body part of the bat. Then, when the hitter swings the warm-up implementation, the auditory and tactile feedback provided when the lateral / lateral movement / movement / offset occurs will provide the hitter with the feeling of hitting the ball.

In the aforementioned embodiment of the baseball bat swing training device described in this section, the bat has a solid longitudinal interior, and the longitudinal cavity can be formed on the upper end of the handle portion after cutting the bat and removing the aforementioned longitudinal portion. In one implementation of this particular embodiment, the longitudinal cavity has a circular radial cross-sectional shape, and the radial outer surface of the handle mating post 216 can be threaded, thus allowing the post 216 to be screwed into the cavity, The upper end of the handle portion is firmly connected to the column-shaped rail guide block 202. In a version of this particular implementation, the handle matches the The thread is counterclockwise, which has the advantage that when the right-handed hitter swings the bat, the connection between the upper end of the handle portion and the track guide block 202 can be kept tight / tight. In another version of this particular implementation, the thread on the handle mating post 216 is clockwise, which has the advantage that when the left-handed hitter swings the bat, it can maintain the upper end of the handle portion and the track guide block 202 The connection between them is tight / tight. In another implementation of this particular embodiment, the radial outer surface of the handle fitting post 216 does not have threads (eg, smooth), and the longitudinal cavity can have any radial cross-sectional shape (eg, round, square , Hexagons and triangles, and other two-dimensional shapes), by inserting the post 216 into the cavity (using the aforementioned strong adhesive to fasten the radially outer surface of the adhesive post 216 to the radial wall of the cavity) The upper end of the handle part is tightly connected to the rail guide block 202. In the aforementioned another embodiment of the baseball bat swing training device, the bat has a hollow longitudinal interior, and a longitudinal cavity with a circular radial cross-sectional shape naturally exists at the upper end of the handle portion, wherein the longitudinal axis of the cavity and the handle The longitudinal axis of the upper part of the part is aligned. In an exemplary implementation of this particular embodiment, the radial outer surface of the handle mating post 216 does not have threads, and the post 216 can be inserted into the longitudinal cavity (using a strong adhesive to secure the radial direction of the adhesive post 216 The outer surface to the radial wall of the cavity) tightly connects the upper end of the handle portion with the rail guide block 202.

Generally speaking, and referring again to FIGS. 4 and 16 to 24, the cylindrical track guide block 202, the front ball bearing 26/28, the rear ball bearing 30/32, and the cylindrical slide rail assembly 204 cooperate to allow the assembly 204 Low friction lateral / lateral movement relative to the track guide 202 (Eg, a lateral / lateral offset), the movement / offset is limited to the aforementioned maximum track movement distance D1. In particular, the slide block 212 of the column-shaped slide rail part 206 has the aforementioned width W1 and includes a pair of opposed extended rail slots 222 and 224 (ie, a front rail slot 222 and a rear rail slot 224). As shown in FIGS. 4 and 19, the positioning of the rail slots 222 and 224 ensures that the horizontal plane of the longitudinal axis thereof is orthogonal to the longitudinal axis Y5 of the slide rail part 206. The upper part of the guide pad 218 of the cylindrical track guide block 202 includes a linear guide channel 226, which passes through the left side 228 of the guide pad 218 to the right side 230. The channel 226 is usually adapted to be received in sliding contact The combination of the slide block 212 and the front and rear ball bearings 26/28/30/32 (when the combination slides into the channel 226). In particular, the vertical axis of the linear guide channel 226 is aligned with the common longitudinal axis Y6 of the aforementioned rail guide block 202. The guide channel 226 has parallel vertical side walls and a pair of opposed extended guide slots 232 and 234 (ie, a front guide slot 232 and a rear guide slot 234), wherein the front guide slot 232 is located in the channel On one side wall of 226, the rear guide slot 234 is located on the other side wall of the channel 226. As shown in FIGS. 4 and 23, the front and rear guide slots 232 and 234 are located on the respective side walls so that the horizontal plane of the longitudinal axis is orthogonal to the longitudinal axis Y6. The guide channel 226 also has the aforementioned width W2, which is slightly larger than the width W1, thus allowing the slide rail block 212 to move and position within the channel 226. The front rail slot 222 and the front guide slot 232 have a common shape and are slightly smaller than a half circle, which is sized to allow the slots 222 and 232 to receive the front ball bearings 26/28 (when Slide block 212 is located in the guide channel 226). The front ball bearings 26/28 are therefore used to slightly separate the front rail slot 222 from the front guide slot 232. In an exemplary embodiment of the cylindrical sliding mechanism 200, the size and shape of the front rail slot 222 and the front guide slot 232 match the size and shape of a part of the outer surface of the front ball bearing 26/28, so Each contact between each ball bearing 26/28 and the slots 222 and 232 will be equally distributed over the entire surface of each ball bearing 26/28, thereby minimizing the friction between these slots and the ball bearings. Similarly, the rear rail slot 224 and the rear guide slot 234 have a common shape and are slightly smaller than a half circle, which is sized to allow the slots 224 and 234 to receive the rear ball bearing 30 / in a low-friction rolling contact manner 32 (when the slide rail block 212 is located in the guide channel 226). The rear ball bearing 30/32 is therefore used to slightly separate the rear rail slot 224 from the rear guide slot 234. In an exemplary embodiment of the sliding mechanism 200, the size and shape of the rear rail slot 224 and the rear guide slot 234 match the size and shape of a portion of the outer surface of the rear ball bearing 30/32, so the balls Each contact between the bearings 30/32 and the slots 224 and 234 will be equally distributed over the entire surface of each ball bearing 30/32, thereby minimizing the friction between these slots and the ball bearings. Therefore, when the slide rail pad 212 has been moved and positioned in the guide channel 226, the front ball bearings 26/28 have rotated and slidingly inserted into the front rail slots 222 and the front guide slots 232, and the rear ball bearings 30/32 have After rotating and slidingly inserting the rear rail slot 224 and the rear guide slot 234, the slide rail part 206 (and the slide rail assembly 204) can be allowed to The longitudinal axis Y5 (and the longitudinal axis of the slide rail assembly 204) and the longitudinal axis Y6 of the rail guide block 202 slide / move in orthogonal directions.

Referring again to Figures 4, 16, 18, 19, 22, and 23, in an exemplary implementation of the cylindrical sliding mechanism 200, the difference between the above widths W1 and W2 is greater than or equal to 1.0 mm and less than or It is equal to 2.0 mm. The cylindrical slide rail part 206 may optionally include one or more weight-reducing orifices (not shown) for further reducing the weight of the cylindrical slide mechanism 200, without negatively affecting the structural integrity of the slide rail part 206 Next, the size of the orifices is set to be as large as possible. Similarly, the column-shaped rail guide block 202 may optionally include one or more weight-reducing orifices (also not shown) for further reducing the weight of the sliding mechanism 200 without affecting the rail guide block 202 negatively. Under structural integrity, the size of the orifices is set to be as large as possible. The outer edges and corners of the sliding mechanism 200 can be selectively rounded to avoid injury to the golfer and further reduce the weight of the sliding mechanism 200.

As shown in FIGS. 5, 6 and 21 to 24, the guide pad 218 of the cylindrical track guide block 202 also includes a track travel distance limitation on the bottom surface 238 of the guide channel 226 of the track guide block Cavity 236. It should be noted that the track movement distance limiting cavity 236 represents another embodiment of the aforementioned track movement distance limiting structure 40. The orbital movement distance limiting cavity 236 has the aforementioned width W3, the aforementioned length L2, and a preset depth D8 (which is greater than the aforementioned protruding distance). As shown in FIGS. 17 to 20, the cylindrical slide rail part 206 includes a longitudinal aperture 240 which is passed through the slide rail part 206 to reach its bottom 246 (which is the Bottom), wherein the longitudinal axis of the orifice 240 is aligned with the common longitudinal axis Y5 of the barrel fitting post 210 and the slide rail block 212. In other words, the orifice 240 is coaxial with the cylinder body matching post 210 and the slide rail block 212. The orifice 240 has a preset radial cross-sectional shape and a preset diameter D9. As shown in FIG. 16, the cylindrical sliding restricting part 208 fastened into the opening 240 includes an opening-fitting post 242 (representing another embodiment of the aforementioned post 36) and a head firmly connected to the top of the post 242 244. The post 242 has the same radial cross-sectional shape as that of the orifice 240. The post 242 also has a preset length L6 and the aforementioned diameter D2, which is selected to allow the post 242 to be inserted completely and firmly down into the aperture 240, so after this insertion, the post 242 is moved from the bottom of the slide rail part 206 246 protrudes (a part of the protrusion is shown in FIG. 4), and the bottom of the post 242 moves toward the track to limit the protrusion distance in the cavity 236.

Referring again to FIGS. 16-20, in one implementation of the cylindrical sliding mechanism 200, the longitudinal aperture 240 may have a circular radial cross-sectional shape and may be threaded, and the aperture may also fit the radial outer surface of the column 242 Threads are formed to allow the post 242 to be screw-connected with the orifice 240, and the post-type slide restricting part 208 is tightly inserted into the post-type slide rail part 206 by completely screwing the post 242 into the orifice 240. In this particular implementation, a lock washer (not shown) can be selectively connected to the post 242 before it is screwed into the hole 240; when the post 242 is completely screwed into the hole 240, the lock washer will be clamped to the head Between the bottom of the portion 244 and the top of the cylinder matching column 210. In another implementation of the sliding mechanism 200, the orifice 240 is not threaded, and the radial outer surface of the post 242 is not threaded, orifice 240 Can have any radial cross-sectional shape (eg, round, square, hexagon, and other two-dimensional shapes), by inserting the post 242 into the aperture 240 (using the aforementioned strong adhesive to secure the diameter of the bonded post 242 From the outer surface to the radial wall of the orifice 240), the slide restricting part 208 is firmly inserted into the slide rail part 206.

Referring again to FIGS. 2 to 6 and FIGS. 16 to 24, the ball bearing retainer structure 38 is usually adapted to move and position the slide block 212 of the cylindrical slide rail part 206 on the cylindrical track guide block 202 Of the guide channel 226, the front ball bearing 26/28 is held between the front rail slot 222 and the front guide slot 232, and the rear ball bearing 30/32 is held in the rear track slot 224 and the rear guide Lead between slots 234. It should be noted that the ball bearing retainer structure 38 can be implemented in a variety of ways. As an example, but not limited, in the embodiment of the cylindrical slide rail assembly 204 shown in FIGS. 2 to 4 and 16 to 19, the ball bearing retainer structure 38 is implemented in the following manner. The ball bearing retainer structure includes the aforementioned front ball bearing retainer parts 110 and 114, and the rear ball bearing retainer parts 112 and 116. The slide rail block 212 includes a pair of front retainer part cavities 248 and 250 and a pair of rear retainer part cavities 252 and 254, wherein each longitudinal axis of these cavities 248/250/252/254 is located in the aforementioned track insert The grooves 222 and 224 are positioned on the horizontal surface (as shown in Figures 17 and 19), and the size and shape of the cavities 248/250/252/254 are adjusted to allow the retainer part 110/112 / A specific post of 114/116 (e.g., post 164) is fully and securely inserted into the cavity so that the head of the retainer part (e.g., head 166) and the slide rail block 212 Left side 256 or right side 258 contacts (as shown in Figures 2 to 4). In an implementation of the slide rail assembly 204, the cavities 248/250/252/254 all have a circular radial cross-sectional shape and can be formed with threads, and the retaining ring parts 110/112/114/116 are radially outward The surface can also be threaded, allowing it to be screwed into a specific cavity in the cavity 248/250/252/254. As shown in Figures 3 and 4, the head of each retainer part 110/112/114/116 is selected, and its radial size allows the head to cover a specific end of one of the rail slots 222/224 Design a part, where the part is large enough to prevent the ball bearings 26/28/30/32 from falling off the sliding mechanism 200 (when it is fully assembled, anyway swing the baseball bat), and small enough to allow the assembly 204 to guide relative to the track The aforementioned lateral / lateral movement of the block 202 (e.g., the front ball bearing retainer parts 110 and 114 hold the front ball bearing 26/28 between the front rail slot 222 and the front guide slot 232, and the rear ball bearing retainer Parts 112 and 116 hold the rear ball bearing 30/32 between the rear rail slot 224 and the rear guide slot 234).

As shown in FIGS. 4 to 6, this section explains the functional operation of the cylindrical sliding mechanism 200, and referring again to FIGS. 16 to 24, after the cylindrical sliding mechanism 200 has been completely assembled, the hole of the cylindrical sliding restricting part 208 The length L6 of the mouth-fitting post 242 is selected so that the bottom of the post 242 moves toward the rail on the post-shaped rail guide block 202 to limit the protrusion distance in the cavity 236 from the aforementioned projection. Now, as will be described in more detail, the cavity 236 is adapted to limit the movement of the cylindrical rail assembly 204 (eg, to restrict the lateral / lateral movement / movement / offset) to the maximum orbital movement distance D1 (through the column The movement limit of 242 is this distance D1). In particular, the cavity 236 has a pair of opposed vertical side walls 176 and 178 that are parallel to each other and parallel to the vertical side walls of the linear guide channel 226 of the track guide block. The cavity 236 has another pair of opposing vertical side walls 180 and 182, which are symmetrical to each other, wherein the horizontal center portions of both side walls 180 and 182 are orthogonal to the sliding / moving direction of the cylindrical slide rail part 206, and thus are also The sliding / moving directions of the column 242 of the part 208 are orthogonal. As shown in FIGS. 5 and 6, the width W3 and the length L2 of the cavity 236 are larger than the diameter D2 of the post 242, thus allowing the post 242 to move inside the cavity 236 (eg, from the second, third, fifth, and (The angle of view of Figure 6 is left and right). As shown in Figures 5 and 6, the difference between the length L2 and the diameter D2 determines the distance D1. When the slide rail assembly 204 is located at the coaxial position of the aforementioned rail guide block 202, the right side of the post 242 is in contact with the side wall 182, as shown in FIG. When the slide rail assembly 204 is in the most non-coaxial position of the aforementioned track guide block 202, the left side of the post 242 is in contact with the side wall 180, as shown in FIG. In general, the length L2 and the diameter D2 can be selected so that the distance D1 can have any value, where the value is selected based on the rigidity of the baseball bat (compared to other factors). By way of example but not limitation, in one exemplary embodiment of the sliding mechanism 200, the length L2 and the diameter D2 are selected such that the distance D1 is approximately 3.5 mm.

In view of the above, and referring again to Figures 5, 6, and 16, it should be understood that the cylindrical sliding mechanism 200 allows the player to hear and feel that the lower end of the body portion of the baseball bat is relative to Lateral / lateral movement / movement / offset at the upper end of the handle portion. In other words In other words, when the sliding mechanism 200 is inserted into the bat as described herein, the sliding mechanism 200 can provide the aforementioned auditory and tactile feedback to the hitter, indicating whether it has achieved the desired swing contour. For example, when swinging the bat so that the lower end of the bat body part is moved laterally / laterally to the left relative to the upper end of the bat handle part, the cylindrical slide rail assembly 204 can be guided on the cylindrical track guide block 202 Up to the maximum non-coaxial position, and the left side of the orifice matching post 242 will hit the vertical side wall 180 of the track travel distance limiting cavity 236, the sliding mechanism 200 can produce a recognizable sound (for example, the hitter will hear a "Snapping" sounds will also produce a tactile sensation at the proximal end of the bat (for example, the batter will feel the vibration from the sliding mechanism 200 traveling through the bat handle part and into his hand).

Therefore, when the aforementioned slide rail assembly (not shown) is located at the aforementioned coaxial position on the track guide block 264, the aforementioned post 36/160/242 of the slide restricting part is located at the center of the track moving distance restricting structure 262. When the slide rail assembly is located at the rightmost position on the track guide block 264 (when the sports device is swung, the lower end of the distal end portion of the device relative to the upper end of the proximal end portion of the device occurs to the right lateral / side It can happen when moving / shifting), the right side of the post 36/160/242 is in contact with the side wall 266 of the track movement distance limiting structure 262. When the slide rail assembly is located at the leftmost position on the track guide block 264 (when the sports device is swung, the lower end of the distal end portion of the device relative to the upper end of the proximal end portion of the device occurs laterally / laterally to the left It can occur when moving / shifting), the left side of the post 36/160/242 is in contact with the side wall 268 of the track movement distance limiting structure 262. In view of the above, it should be understood that the orbital movement distance between the coaxial and the rightmost position is the aforementioned maximum orbital movement distance One-half of D1 (when D1 is 3.5 mm, it is 1.75 mm). Similarly, the orbital movement distance between the aforementioned coaxial and leftmost position is also half of the distance D1.

In addition, a speed sensor can be placed at an appropriate position on the sports equipment, and the speed sensor can measure the speed when the equipment is swung. For example, when the sports equipment is a baseball bat, the speed sensor may be placed at the distal end of the bat to measure the swing speed of the bat. Depending on the particular type of sports device in which the sliding mechanism is inserted, the radial thickness of the gap-forming region of the device may increase to prevent the training device embodiment from breaking. A non-sliding part can be adapted to replace the sliding mechanism inserted in the specified type of sports equipment. In other words, the non-sliding part can be used to replace the sliding mechanism and reconnect its proximal and distal portions so that the lower end of the distal portion and the upper end of the proximal portion remain substantially coaxially aligned regardless of the swing of the instrument , Thereby converting the device back to its original form and function. A longitudinal cavity may be formed in the proximal end portion of the sports equipment, the cavity moves from the distal end of the proximal end portion to the proximal end thereof, and the aforementioned recognizable sound is allowed to be emitted from the proximal end of the proximal end portion. A longitudinal cavity may also be formed in the distal portion of the sports equipment, the cavity moving from the distal end of the distal portion to its proximal end, and allowing a recognizable sound from the distal end of the distal portion.
