Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a golf practice device. More particularly, the invention relates to an apparatus by which a golf swing can be simulated in a reproducible and repeatable manner.

Conventionally, for example, British Patent Specification No. 1500322,
No. 1258018, No. 1144180, No. 1009090 and No.
Many golf swing simulator devices have been proposed, such as No. 597,724. No. 1009090 in this
No. 1,144,180 includes a golf club provided in the hand grasping region by a curved handle pivoted to one end of the arm about a pivot axis extending through the handle. The other end of the arm is pivoted about another axis to a pedestal that is vertically adjustable on a support such as a wall or post. The two axes are generally parallel to each other in a defined relationship. The length of the arm is adjustable so that the distance between the two axes can be changed, so that one of the two axes passes through the user's hand and the other Passes through the user's waist. No. 1009090 changes the swing surface by adjusting the angle that both axes make with the horizontal plane. No.
In No. 1144180, the upper end of the arm is pivotally supported and the swing plane at the upper end of the swing is changed by this horizontal pivot axis, but the basic swing plane at the lower end of the swing is not adjustable. Therefore, the range of adjustment is limited, and the swing surface as a whole is not finely adjusted. In No. 1009090, the swing surface is finely adjusted, but when the swing surface is adjusted, the lie angle of the club becomes incorrect. No. 597,724 discloses a device similar in some respects to the device described above, but with a universal joint between the handle and the arm, which cannot be adjusted except when the club is in contact with the ground, and which does not allow adjustment of the club's position during the swing. cannot be adjusted at all.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of conventional devices, and to provide a better way to accurately reflect the actual golf swing, give the user complete control over the user's swing, and make the correct swing. To provide a golf swing simulator device from which a model and practice can be obtained and which can be easily adjusted according to the physical characteristics of the user.

The present invention is a golf swing simulator device comprising: a handle or a handle shaped like the handle of a golf club; a mounting member for mounting the device to a stationary support; and a chain member for connecting the handle to the mounting member. The chain member is configured such that one end of the arm is pivotally connected to the mounting member around the first pivot axis, and the arm is configured such that the other end of the arm forms a circle around the first pivot axis. 1st above
an arm extending away from the rotational axis;
One end of the curved handle is pivotally connected to a second pivot axis passing through the handle at a distance from the pivot axis, and the handle is spaced from a pivot coupling member colinear with the second pivot axis. The other end of the curved handle is rotatable relative to the handle around the longitudinal axis of the handle, and the effective length of the arm is adjusted or the angle between the arm and the first rotation axis is changed. A golf swing simulator device comprising: a swing radius adjusting member that can be set by adjusting the swing radius; and a swing surface adjusting member that is provided on the mounting member and can be set by changing the angle that the first rotation axis makes with a horizontal plane; The golf swing simulator is provided with a lie angle adjustment member that changes and sets the lie angle of the handle, and the lie angle adjustment member is disposed between the other end of the arm and the rotational connection member. .

By adjusting the position of the hand (adjustment here refers to changing the position and setting it in that position) in a predetermined sequence throughout the golf swing, the device also allows the wrist and hand to move in a very natural manner. An understandable approach is to bend and rotate it to simulate a golf swing through the user's hands. Adjustment and movement of the device is accomplished mechanically, with the device being mounted on a stationary support facing the user and in a natural downward position relative to the user's hand. There is no need for the swing axis to pass through the user's waist, and there is no need for it to be angularly invariant with respect to the rotation angle of the hand. Furthermore, the lie angle of the club can be adjusted independently of other adjustments.

As shown in FIG. 1, the device of the present invention includes a handle 10 shaped like the handle of a golf club;
A mounting member for attaching the device to a stationary vertical support, such as a wall 12, and a chain member connecting the handle are provided. The mounting member includes a bracket 14 that is adjustable in the vertical direction with respect to the slider 15;
An angularly adjustable member 16 is provided around a horizontal pin 18 extending parallel to the wall. By combining the pin 18 with a screw or other mechanical member (not shown), the member 16 can be adjusted to a desired mounting position and then tightened to prevent the member 16 from rotating relative to the bracket.

The chain member connecting member 16 to handle 10 includes an arm 20 and a curved handle 22. A head 24 is integrally formed at one end of the arm 20, and the arm 20 is connected via the head 24.
is pivoted to member 16 about axis 26 . Said axis makes an angle α with the horizontal, and this angle is adjustable at the location of the pin 18. arm 20
Since the other end is connected to one end of the curved handle 22 via the rotational connection member 30, the curved handle 22 can rotate around the axis 28. The pivoting coupling member 30 is connected to the arm 20 via a pair of coupling elements 21 and 23 that are adjustably coupled to each other at a pivot 36 so that the angle between the axes 28 and 26 can be varied. The other end of the curved handle 22 pivots the lower end of the handle 10 at a location 32, so the handle 10
is pivotable relative to the curved handle 22 about the longitudinal axis 34 of the handle.

As can be seen in FIG. 1, axes 28 and 34 preferably intersect at a 90° angle;
0 is spaced apart from the rotational coupling member 30. If necessary, the angle β between the axis 26 and the arm 20 can be adjusted by providing another angle-adjustable connecting member at the upper end of the arm 20, for example the head 24. However, depending on, for example, the position of the head 24 or the attachment position of the connecting element 23, or the attachment position of both, the arm 20
It is desirable to adjust the effective working length of.

When using this device, move the slider 15 to the wall 12.
and place bracket 1 at a certain position on the slider.
Temporarily fasten 4.

The user decides what type of club to use to simulate the swing. Each club has a unique lie angle, or the angle the shaft makes with the ground when the club hits the ball, and a unique address height, or STANDIG HEIGHT, or the vertical distance from the top of the handle to the ground when the club hits the ball. It has a height. The member 16 is then adjusted relative to the bracket 14 so that the axis 26 is at the appropriate angle with respect to the horizontal. This determines the swing plane. Connecting elements 21 and 23 are then adjusted at pivot 36 to provide the proper lie angle of the club with the suspended device at rest as shown. Also, the effective length of the arm 20 is adjusted to suit the user. The above is determined by the radius of the swing and possibly the arm length of the user. Swing radius is the vertical distance between club head 100 and axis 26, shown in phantom.
The swing radius can be adjusted as follows. As mentioned above, this swing radius is arm 20
can be changed by changing the effective length of . That is, when the connecting element is moved along the arm 20 in the X direction, the club head 100 correspondingly moves.
The swing radius changes by moving in the X′ direction. At this time, the angles α, β and lie angle γ do not change.

Another method of adjustment is to change the angle β between axis 26 and arm 20. This causes the connecting element 23 to move in the Y direction, and the club head 100 to move in the Y' direction, changing the swing radius. However, since the angle β is changed, the lie angle γ also changes accordingly, so in order to return the lie angle to its original value, the pivot part 3
It is necessary to adjust the angle of 6. At this time, the club head 100 moves slightly in approximately the X' direction, and the swing radius changes. Finally, the position of the bracket on the slider 15 is adjusted to provide the correct lie angle of the handle when the device is at rest as shown. By properly adjusting the various components of the device in this way, a nearly ideal swing condition is established for the user. By attaching the grip of a normal golf club to the handle, the user can make a swing similar to that of a normal golf ball. After adjusting the simulator, the user can perform the prescribed swing to practice in a relatively limited area and conveniently for the user.

Another feature of the illustrated device is that the handle 10 can be held by using the curved handle 22 so that the axis 28 passes through the user's hand. The coupling member 30 allows the handle to pivot about the axis 28, thus making it possible to raise or lower the hand in a reliable manner.
The coupling member 32 allows the handle 10 and therefore the user's hand to be rotated about the handle axis 34. Also, if desired, a pointer 35 can be provided perpendicular to the axis of the handle to indicate the angular position of the club head during the swing.

A variant of the device of the invention allows for movement of the hand along the axis 34 during the swing by sliding the handle 10 axially on its central spindle. The handle can be returned to its normal position by means of a compression spring 37.

The device of the invention has three types of rotation, A, B and C, about axes 26, 28 and 34. In addition, four adjusting portions D, E, F, and G are provided at the locations of the slider 15 and the pin 18. Rotation type A about axis 26 provides the basic swing. Axis line 28
The hand can be raised by rotation type B around. The rotation type C about the axis 34 allows the club to be rotated about the axis. This rotation occurs naturally during a normal swing, as evidenced by the attitude of the club head. Adjustment D sets the address height. Adjustment E determines the swing plane. Adjustment F determines the swing radius. Adjustment G
determines the lie angle. The device of the invention can be of only three rotation types and without adjustment. The devices described above are designed for special clubs and special users with special swings. However, in order for the device to be used by different users or to simulate the use of different clubs, it is commercially attractive and desirable to include one or more adjustments. A grade or other mark may be attached to some or all of the above-mentioned adjustment parts to indicate the set setting, thereby avoiding elaborate measurements or trial and error for setting. A table may also be provided showing the relationship of the markings to club type, swing plane, and user's body dimensions.

In FIG. 2, instead of the member 16 being pivotally connected to the bracket 14, the member 16 is mounted by screws or the like (not shown) at various locations on the concavely curved surface 14a of the member 14. Can be made into a block shape that can be installed. Member 14 may be directly or
It is provided on the wall 12 via an intermediate material such as a slider 15 shown in the figure. This modified form is shown in FIG. When the member 16 is moved up and down along the curved surface 14a, the angle α between the axis 26 and the horizontal, that is, the swing plane changes. In the device shown in FIG. 1, when the member 16 is rotated about the axis 18 to change the swing plane, the handle 10 is raised and lowered. However, in the embodiment shown in FIG.
6 is partially or completely compensated for, the handle is placed in the same position, and the effort required for subsequent adjustment is greatly reduced. In FIG. 2, a dashed line indicates an extreme position where the swing plane is vertical, that is, α=0. A symbol with a dash indicates the new position above. The swing axis is moved to a horizontal position 26' and the block is moved to a position 16' on the curved surface 14a. Adjust the angle G', which is smaller than the angle G, at the pivot 36 to keep the lie angle of the club the same. The swing radius R can be taken from the intersection X of the axes 28 and 34 at right angles to the axis 26. The arm 20' can be moved upward by the connecting element 23 to return the swing radius R' to the same position as R. Since the handle 14a has a curved surface arrangement, the handle returns to almost its original height when the above is done. It should be noted that in this case a slight adjustment of the member 14 relative to the wall 12 is necessary.

Attachments are attached to the lower end of the handle to attach a removable and replaceable club shaft and head. Also, in place of the permanent handle 10, a rotatable fastener or other device may be provided about the axis 34 for attaching a real golf club. Another useful feature of the present invention is that it can be made much more robust than many previously proposed devices. Since the golf swing simulator device of the present invention is configured as described above, it has the following effects.

Since the lie angle adjusting member 36 is provided between the first rotation axis 26 and the second rotation axis 28, the lie angle adjusting member 36 is provided between the first rotation axis 26 and the second rotation axis 28. Adjust (change, set) to fit
Adjustments to one of the swing radius, swing plane and lie angle do not affect the other adjustments. By correctly adjusting the swing radius adjusting member, the swing surface adjusting member, and the lie angle adjusting member, a swing condition that is approximately ideal for the user can be determined.

Further, since the curved handle 22 is provided, the handle 10 can be held so that the second rotation axis 28 passes through the user's hand, and the user's hand can be rotated around the handle axis 34. Can be done.

When the pointer 35 is provided perpendicular to the axis of the handle, the angular position of the club head can be easily determined.
