BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to an adjustable training device to be used by those wishing to practice playing tennis, golf, basketball as well as a variety of other sports and non-sports-related activities. The training device has a hoop that can be elevated or lowered and rotated between vertical and horizontal positions to enable the player to hit, throw, kick or shoot a ball through the hoop at different locations above the ground and thereby practice a variety of different shots and techniques.
2. Background Art
It is known that tennis and golf players wishing to practice their game will use a target to which a ball is hit. In the case of tennis, a player will stand on one side of the tennis net and move the target to the opposite side of the net. The player tries to hit a tennis ball over the net so as to land close to the target. In the case of golf, a player will place the target on the green or fairway at a particular distance and then try to hit a golf ball so as to land close to the target.
Although the player may be able to hit his tennis or golf ball close to the target, there is nothing between the player and the target to help the player improve the fundamentals of his game. For example, despite the tennis player being able to hit his tennis ball to a designated target on the court, there is no way to ensure the proper form and ball location during the player's serve, ground strokes, volley, etc. relative to the net. Likewise, there is nothing to enable the golfer to improve the form of his strokes and the flight of the ball while pitching, driving, etc.
Therefore, what would be advantageous is a portable practice device to be used with and without a target and by both tennis players and golfers, where the practice device is adjustable so that the players can hit their tennis and golf balls towards the device in order to practice different strokes and hitting techniques over different distances and thereby improve their form.
SUMMARY OF THE INVENTIONIn general terms and according to a first preferred embodiment, a portable tennis and golf training device is disclosed to be used to enable a player to practice his tennis and golf strokes by hitting a tennis or golf ball through an adjustable hoop. The training device has a stand with a set of collapsible and extendable legs to enhance stability when the device is laid on a tennis court, grass or other flat surface. A hollow tubular lower height-adjustment member is coupled to and extends vertically upward from the stand. A hollow tubular intermediate height-adjustment member is telescopically received by and slidable through the lower height-adjustment member. A hollow tubular upper height-adjustment member is telescopically received by and slidable through the intermediate height-adjustment member. The lower, intermediate and upper height-adjustment members can be pulled upwardly and outwardly so as to stand in vertical end-to-end alignment one above the other. Threaded compression nuts surround and interlock the overlapping ends of the lower, intermediate and upper height-adjustment members so as to maintain the vertical end-to-end alignment thereof above the stand.
The practice device includes an adjustable hoop that is coupled to and rotatable relative to the upper height-adjustment member by means of a hoop carrier. The hoop is preferably circular, but may include one or more flat sides or a plurality of arcuate sides that are detachably connected together. One end of the hoop carrier is pivotally connected to the upper height-adjustment member. A mounting sleeve having a channel running longitudinally therethrough is fixedly connected to the opposite end of the hoop carrier. The adjustable hoop is received by and retained within the channel through the mounting sleeve. A curved guide rail is detachably connected to the top of the upper height-adjustment member. The hoop carrier is adapted to rotate over the curved guide rail to cause a corresponding rotation of the mounting sleeve and the hoop that is retained by the mounting sleeve so that the position of the hoop is adjustable through an arc which extends between a vertical position facing the player and a horizontal position facing the ground. Once the position of the hoop is selected, a fastener (e.g., a pull pin) is removably inserted through axially-aligned holes formed in the hoop carrier and the guide rail to prevent a displacement of the hoop carrier and the hoop which is carried thereby.
In operation, once the position of the hoop is selected and locked in place by the fastener, the stand of the practice device is stationed as desired on a tennis court adjacent the net or on a green or fairway of a golf course. The tennis or golf player practices his stroke and form while attempting to hit a tennis ball or golf ball through the hoop which extends above the stand.
According to another preferred embodiment, a portable training device is disclosed to be used for a variety of sports (e.g., basketball) and non-sports related activities. The training device has a collapsible stand with a set of folding legs that are rotatable between horizontally extended and vertically collapsed positions. Lower, intermediate and upper height adjustment members are telescopically received and slidable one within the other so as to stand vertically upward between the stand and a rotatable hoop. An end cap surrounds the top of each of the lower and intermediate height adjustment members. Each end cap has a locking collar through which the intermediate and upper height adjustment members are pulled or pushed to adjust the elevation of the hoop above the ground. A locking bolt is manipulated to compress each of the locking collars and thereby hold the lower, intermediate and upper height adjustment members in end-to-end alignment with one another.
The rotatable hoop is pivotally connected to and detachable from the top of the upper height adjustment member by means of a hoop connector. A threaded locking pin is pushed through the upper height adjustment member and the hoop connector to be connected to a threaded knob and thereby establish an axle around which the hoop can rotate between vertical and horizontal positions depending upon the activity to be practiced. That is, the position of the rotatable hoop is selectively adjustable above the stand both vertically (by means of raising or lowering the lower, intermediate and upper height adjustment members) and horizontally (by rotating the hoop at the hoop connector relative to the height adjustment members).
The rotatable hoop can be separated (i.e., pulled off) from the upper height adjustment member at the hoop connector. In this case, one end of a horizontal cross bar is detachably connected to the top of the upper height adjustment member by means of a first elbow joint. A vertical suspension bar is detachably connected to the opposite end of the horizontal cross bar by means of a second elbow joint so that the suspension bar depends downwardly from the cross bar towards the ground. The rotatable hoop is now detachably connected to the suspension bar at the hoop connector, whereby the hoop is suspended from and held by the suspension bar above the ground. The elevation of the rotatable hoop off the ground can be selectively adjusted by means of raising or lowering the lower, intermediate and upper height adjustment members above the stand.
Referring initially to
As will be described in greater detail hereinafter, the tennis training device 1 includes a hoop 3 at the top thereof. The position of the hoop 3 can be selectively adjusted relative to the tennis net 50 in both linear (i.e., vertical) and rotational directions so that a tennis player can practice his form and strokes while hitting a tennis ball through the hoop. The player can use the tennis training device 1 with or without the target 60. In the case where the target 60 is employed, the position of the hoop 3 and the location of the target 60 can be adjusted relative to one another so that the player practices hitting a tennis ball through the hoop to land close to the target.
The adjustable hoop 3 enables the player to practice his volley shots while standing close to the hoop and/or his serve and ground strokes standing away from the hoop. At the same time, the position of the hoop 3 above the net 50 can be selectively adjusted depending upon the age and height of the player. In any case, the hoop 3 of training device 1 helps the player practice hitting a tennis ball to a particular location and elevation above the net 50 so as to reach the target 60. For more advanced players, the player can also practice applying spin to a ball and the arc along which the tennis ball must travel to pass through the hoop 3 from different positions on the tennis court. What is more, the hoop 3 can be lowered so that the bottom thereof lies below the top of the tennis net 50. This will cause the player to practice hitting the tennis ball through a smaller hoop area lying close to and just above the top of the net 50 which is desirable in many game situations.
The hoop 3 of tennis training device 1 is shown in
Referring now to
The hoop support of the tennis training device 1 also includes a hollow tubular intermediate height-adjustment member 14. The intermediate height-adjustment member 14 is shaped and sized (i.e., with a smaller diameter) so as to be slidably and telescopically received within the hollow tubular lower height-adjustment member 9. The intermediate height-adjustment member 14 can be pulled outwardly or pushed inwardly of the lower height-adjustment member 9 as is needed in order to correspondingly adjust the height above the base 5 of the hoop 3 that is carried at the top of the training device 1.
A well-known threaded compression nut 16 which surrounds the intermediate height-adjustment member 14 is rotated into mating engagement with a correspondingly threaded portion of the lower height-adjustment member 9 so that the overlapping ends of the lower height-adjustment member 9 and the intermediate height-adjustment member 14 will be held in place standing vertically one above the other. Rather than the aforementioned threaded nut 16, a removable locking pin (not shown) can be inserted through axially-aligned locking holes (also not shown) in order to hold the intermediate and lower height-adjustment members 14 and 9 one above the other. By way of example, a suitable locking pin can be any of a spring-loaded plunge pin, hitch pin, pull ring pin, or the like.
The hoop support of the tennis training device 1 also includes a hollow tubular upper height-adjustment member 18. The upper height-adjustment member 18 is shaped and sized (i.e., with a smaller diameter) to be slidably and telescopically received within the intermediate height-adjustment member 14. The upper height-adjustment member 18 can be pulled outwardly or pushed inwardly of the intermediate height-adjustment member 14 as is needed to correspondingly adjust the height above the base 5 of the hoop 3 that is carried at the top of the training device 1.
A threaded compression nut 20 which surrounds the upper height-adjustment member 18 is rotated into mating engagement with a correspondingly threaded portion of the intermediate height-adjustment member 14 so that the overlapping ends of the upper and intermediate height-adjustment members 18 and 14 will be held in place standing upwardly one above the other. The threaded nut 20 which holds the overlapping ends of the height-adjustment members 14 and 18 may be identical to that described when referring to the end-to-end engagement of the intermediate height-adjustment member 14 to the lower height-adjustment member 9.
The previously described adjustable hoop 3 is coupled to the top of the hollow upper height-adjustment member 18 of the training device 1 so that the hoop 3 can be rotated continuously relative to member 18 through an arc of about 90 degrees from a vertical position, in axial alignment with the upper height-adjustment member 18, to a horizontal position, in perpendicular alignment with member 18. In its vertical position, the central opening through the hoop 3 will face the player to enable serves, volleys, ground strokes, etc. to be practiced. In its horizontal position, the central opening through the hoop 3 will be parallel to the ground to enable dropshots to be practiced. As will soon be explained, the adjustable hoop 3 can be rotated to any location between the vertical and horizontal positions described above depending upon the training activity of the player.
The adjustable hoop 3 is coupled to the upper height-adjustment member 18 by means of a hoop carrier having a pair of spaced, parallel-aligned arms 24. Turning to
A mounting sleeve 28 having a channel 29 running longitudinally therethrough is affixed to the opposite ends of the hoop carrier arms 24. The size and shape of the channel 29 through the mounting sleeve 28 corresponds to the size and shape (i.e., cross-section) of the hoop 3. The hoop 3 is received through and retained in frictional engagement with the sleeve 28 so that the sleeve is rotatable above the upper height-adjustment member 18 of practice device 1 by means of the hoop carrier arms 24. To this end and as was previously explained, the hoop 3 can be manufactured with a straight bottom (designated 4 in
A guide rail 30 having a curved body and stops 31-1 and 31-2 projecting outwardly from opposite ends of the body is connected to the top of the upper height-adjustment member 18. A fastener 32 (of
A series of angle adjustment holes 36 are spaced from one another through the curved body of the guide rail 30. An angle retention hole 38 is formed through each of the pair of rotatable hoop carrier arms 24. The hoop carrier arms 24 are simultaneously rotated along the curved body of guide rail 30 for correspondingly rotating the hoop 3 through the arc between the vertical and horizontal positions (as shown in
The hoop carrier arms 24 are rotated to a desired position over the guide rail 30 until the hoop 3 that is retained by the mounting sleeve 28 is correspondingly rotated as desired between the vertical and horizontal positions of
Like the training device 1 described while referring to
The collapsible stand 82 of the training device 80 has a set of folding legs 88, whereby the stand can be manipulated between a deployed condition (best shown in
The opposite end of each folding leg 88 is pivotally coupled to a pair of leg brackets 92 so as to lie therebetween and be rotatable relative thereto. Each pair of leg brackets 92 extends outwardly from a base 94 that lies in surrounding engagement with the bottom of the set 86 of height-adjustment members. For the training device 80 of
The folding legs 88 of the collapsible stand 82 are preferably hollow elongated tubes or posts. Referring to
A first pair of retractable spring-loaded lock-release snap pins 100-1 and 100-2 projects outwardly from one side of each of the hollow folding legs 88 of the collapsible stand 82. A second pair of retractable snap pins (not shown) projects from the opposite side of each folding leg 82. The pair of snap pins 100-1 and 100-2 are connected to one another so as to move relative to the leg 82 in unison in response to a pushing force applied thereto. A lower first pair of locking holes 102 are axially aligned with one another through each pair of locking brackets 92 to which a folding leg 88 is pivotally coupled. An upper second pair of locking holes 103 are axially aligned with one another through each pair of locking brackets 92. An intermediate third pair of locking holes 104 are axially aligned with one another through, each pair of locking brackets 92.
With the collapsible stand 82 of the training device 80 in its deployed condition of
When it is desirable to manipulate the collapsible stand 82 to its collapsed, condition of
As the folding leg 88 is rotated upwardly towards the set 86 of height-adjustment members, the lock-release snap pins 100-1 and 100-2 are correspondingly rotated until the first snap pin 100-2 is received and captured by the upper locking hole 103 formed in leg bracket 92. That is, the pair of spring-loaded lock-release snap pins 100-1 and 100-2 will be once again urged outwardly from the folding leg 88 so that snap pin 100-2 moves through locking hole 103, whereby to lock the folding leg 88 in its vertical position of
The same process may be followed by applying a pushing force to the second lock-release snap pin 100-1 at each side of the folding leg 88 by which to enable the leg to rotate downwardly in a direction opposite to that of the reference arrow 106 until the first snap pin 100-2 is received in and captured by the lower locking hole 102. Thus, the folding leg 88 of stand 82 will be angled downwardly from the brackets 92 (not shown) to lift the set 86 of height-adjustment members higher above the ground.
Like the previously-disclosed training device 1 of
Each of the height-adjustment members 112, 114 and 116 is preferably an upstanding hollow tube or post extending one above the other. The lower height-adjustment member 112 is attached to the collapsible stand 82 at the base 94.
The intermediate height-adjustment member 116 is shaped and sized (i.e., with a smaller cross section) so as to be slidably and telescopically received within the hollow lower height-adjustment member 112. The intermediate height-adjustment member 116 can be pulled outwardly or pushed inwardly of the lower height-adjustment member 112 as is needed in order to correspondingly adjust the height of the hoop 84 that is carried at the top of the set 86 of height-adjustment members. The intermediate height-adjustment member 116 can be pulled upwardly and outwardly from the lower height-adjustment member 112 so as to lie in vertical end-to-end alignment therewith. In its upstanding position as shown in
The upper height-adjustment member 114 is shaped and sized (i.e., with a smaller cross section) to be slidably and telescopically received within the intermediate height-adjustment member 116. The upper height-adjustment member 114 can be pulled outwardly or pushed inwardly of the intermediate height-adjustment member 116 as is needed to correspondingly adjust the height of the hoop 84 above the stand 82 of the training device 80.
As is best shown in
As earlier described, the intermediate height-adjustment member 116 is slidable through the lower height-adjustment member 112. However, when the locking knob 128 is rotated and the locking bolt 126 is pulled through the bolt sleeves 122 and 124 towards the locking knob, a compressive force is generated by the locking collar 120-1 at the gap 121. In this case, the gap 121 is closed, and the locking collar 120-1 is tightened around the intermediate height-adjustment member 116 to prevent the intermediate member from sliding into or out of the lower height-adjustment member 112. Thus, the intermediate height-adjustment member 116 is held in place relative to the lower height-adjustment member 112 either retracted therewithin as shown in
An end cap 118-2 lies in surrounding engagement with the top of the upper height-adjustment member 114. A flexible locking collar 120-2 having a gap 130 formed therein is co-extensively connected to and located above the end cap 118-2. The locking collar 120-2 surrounds the upper height-adjustment member 114 near the top thereof. A pair of cylindrical, axially-aligned bolt sleeves 132 and 134 are affixed to and spaced from one another along one side of the flexible locking collar 120-2 which surrounds the upper height-adjustment member 114. A threaded locking bolt 136 extends through the cylindrical bolt sleeves 132 and 134. A threaded locking knob 138 is rotated into mating engagement with one end of the threaded locking bolt 136, such that a rotational force applied to the locking knob 138 applies a pulling force to and a corresponding linear displacement of the locking bolt 136 through the axially-aligned bolt sleeves 132 and 134 and towards the knob 138.
As was also previously described, the upper height-adjustment member 114 is slidable through the intermediate height-adjustment member 116. When the locking knob 138 is rotated and the locking bolt 136 is pulled through the bolt sleeves 132 and 134, a compressive force is generated by the locking collar 120-2 at the gap 130, whereby the gap is closed and locking collar is tightened around the upper height-adjustment member 116. When the locking knob 138 is rotated in an opposite direction, the locking pin 136 is loosened within the bolt sleeves 132 and 134 to reduce the compressive force being applied by the locking collar 120-2. Increasing or reducing the compressive force generated by the locking collar 120-2 around the upper height-adjustment member 114 by rotating the locking knob 138 allows the adjustment of the upper height-adjustment member 114 relative to the intermediate height-adjustment member 116 between retracted and extended positions.
Continuing to refer to
The locking pin 146 functions as an axle around which the detachable hoop connector 144 can pivot in order to cause a corresponding rotation of the hoop 84 through an arc of 180 degrees relative to the set 86 of height-adjustment members (of
By virtue of the detachable nature of the hoop connector 144, the rotatable hoop 84 can be separated from the set 86 of height-adjustment member (of

The training device 80-1 includes first and second L-shaped elbow joints 154 and 156, a horizontal cross bar 158, and a vertical suspension bar 160. The first elbow joint 154 includes a hollow receptacle 162 at one end and a slotted hollow receptacle 164 (best shown in
The top of the upper height-adjustment member 114 is removably received within the slotted hollow receptacle 164 of the elbow joint 154 so that the upper member 114 and the joint 154 are detachably connected together. A threaded locking screw 170 is inserted through a hole formed in the upper height-adjustment member 114 and a slot formed in the receptacle 164 of elbow joint 154. A threaded rotatable locking knob 171 is then rotated into releasable mating engagement with one end of the threaded locking screw 170. Accordingly, the horizontal cross bar 158 is held between elbow joints 154 and 156 above the ground, and the vertical suspension bar 160 that is connected to elbow joint 156 depends downwardly therefrom towards the pound.
The rotatable hoop 84 of training device 80-1 is detachably connected to and suspended from the free end of the vertical suspension bar 160 in the same manner in which the hoop is connected to the upper height-adjustment member 114 of the training device 80 in the manner described while referring to the training device 80 of
The versatility of the training device 80-1 is maximized when the hoop connector 144, the vertical suspension bar 160, the horizontal cross bar 158, and the set 86 of height-adjustment members are disconnected from one another. Not only is the disassembly compact to transport and store, but the hoop connector 144 may be connected directly to the upper height adjustment member 114 (as shown in
