Description

  The present invention relates to a ball reiki for manually collecting golf balls used in a driving range or the like.

  Conventionally, in golf driving ranges, automatic collection devices for collecting golf balls have been actively developed throughout the driving range. On the other hand, there are many cases where such collection is not sufficient, and as an apparatus for individually collecting such a golf ball, an unmanned golf ball collecting machine such as Patent Document 1 has been invented. However, golf balls are collected by human naval tactics in a small practice field, and the current situation is that golf balls are also collected using a T-shaped reiki called a dragonfly.

In such a T-shaped reiki, the golf ball collecting part has a rectangular plate shape, and a bar-like part for hand pushing is joined to the central part of the plate-like part at a right angle. .
However, in this conventional technique, when golf is collected, the golf balls are vertically connected in the direction of collecting the balls, and the dimples of the adjacent golf balls are joined to each other, so that the adjacent balls are just like the coupling of the gears. Rotating in the opposite direction, the adjacent ball tries to move in the opposite direction, eventually becomes pushed and pushed, the balls are vertically connected, and even if manually pushed in the collecting direction, the ball does not roll and collects in a non-rotating state The ball was pushed in the direction of the sphere, and there was a limit to manual ball collection (see FIG. 5B).

Japanese Patent Laid-Open No. 8-107953

  An object of the present invention is to provide an efficient ball collecting means for manually collecting golf balls.

  In order to solve the above problems, the configuration of the present invention is to attach a curved plate to the front end of the long handle and the long handle via a bracket, and provide a bracing material diagonally to the left and right via the bracket in the middle of the long handle. The other end is attached to the curved plate via a bracket, and the curved plate has a concave front surface that is the opposite side of the long handle, and the curved plate is provided with two or more rotating bodies at least symmetrically, This is a golf ball reiki in which the lower end of the curved plate is positioned above the ground surface.

  The rotating body of the present invention may be a side roller or a pipe roller.

  According to the first aspect of the present invention, a curved plate is attached to a front end of a long handle and a long handle via a bracket, a bracing material is provided diagonally to the left and right via a bracket in the middle of the long handle, and the other end of the brazing material Is attached to the curved plate via a bracket, and the curved plate has a concave front surface opposite to the long handle, and the curved plate is provided with two or more rotating bodies at least left and right symmetrically. Since the lower end of the golf ball is a reiki for a golf ball positioned above the ground surface, the lower end of the curved plate does not contact the ground surface when the ball is collected, and the collected golf ball is Since the ball moves vertically along the concave curved portion of the ball, the ball does not roll even if it is manually pushed in the direction of collecting the ball. No.

  Further, the rotating body of claim 2 is easy to maintain because the rotating portion is not a large portion as a whole in the case of a side roller. Furthermore, in the pipe roller according to the third aspect, the reiki can reduce the sinking in the concave portion, and the lower portion of the curved plate can prevent the lower surface from contacting the ground surface.

  FIG. 1 is a plan view showing a first embodiment of a golf ball reiki 10 according to the present invention. The golf ball reiki 10 includes a round bar-shaped long handle 20 and a curved plate 30 attached to the front end of the long handle 20 via a tip bracket 40. The long handle 20 and the curved plate 30 are T-shaped in plan view. It has become. The curved plate 30 has a concave surface (see FIG. 2) on the back surface of the surface to which the long handle 20 is attached (see FIG. 2). When the golf ball is pushed by the curved plate 30 with the end of the long handle 20, the golf ball is The ball is curved with the intention of moving upward along the curved plate. The long handle 20 is rounded in cross section so that the user can hold it with both hands, and the portions of the long handle 20 close to the curved plate 30 are slanted to the left and right through the long bracket 42. The other ends of the tension members 22 and 24 are attached to the curved plate 30 via side brackets 44 and 46. The tension members 22 and 24 are for reinforcing the attachment state of the long handle 20 and the curved plate 30.

  The shape such as the long handle is not necessarily limited to the above-described embodiment. Further, it is preferable to use a lightweight material such as FRP (Fiber Reinforced Plastics) as the material of the golf ball reiki 10.

  The curved plate 30 is provided with two side rollers 50 and 52 on the left and right sides and a center roller 60 on the center. The two side rollers 50 and 52 are provided in the vicinity of both ends of the curved plate 30, and provided with reinforcing curved plates 54 and 56 on the front surface side of the curved plate 30, and the wheel fixing frame is interposed via the reinforcing curved plates 54 and 56. 58 and 59 are fixed, and the two side rollers 50 and 52 are fixed to the wheel fixing frames 58 and 59 so that the curved plate 30 is equally held on the left and right. Thus, the two side rollers 50 and 52 are provided in front of the curved surface of the curved plate 30.

  Note that the lower ends of the side rollers 50 and 52 are provided below the U-shaped cover 32 at the lower end of the curved plate 30, whereby the curved plate 30 is positioned above GL (ground level). Since the side rollers 50 and 52 are located in front of the curved surface of the curved plate 30, the golf balls scattered in the GL can be collected.

  As shown in FIGS. 2 and 3, the center roller 60 is provided near the front end bracket 40 at the front end of the long handle 20 and below the long handle 20. The center roller 60 is provided with two rollers on the left and right sides of the long handle 20 by a center roller mounting bracket 62 and a mounting shaft 64 mounted on the center roller mounting bracket 62.

  As shown in FIG. 4, the mounting position of the center roller 60 is such that, in the normal use position (A), the side rollers 50 and 52 are installed on the GL, and the U-shaped cover 32 at the lower end of the curved plate 30 is The rollers 50, 52 are located above the GL installation position (A in the figure), and the center A of the center roller 60 is above the U-shaped cover 32, and the center roller The lower end of 60 is provided at substantially the same position as the lower end of the U-shaped cover 32.

  If the long handle 20 is lowered from the normal use position to the use position (A), the center roller 60 is installed on the GL. At this time, the center of the center roller 60 is B and the tip of the U-shaped cover 32 is A. The position where the center roller 60 is in contact with the GL is the lowest end position of the tip of the U-shaped cover 32. With this configuration, it is possible to prevent the U-shaped cover 32 of the curved plate 30 from being too lowered and contacting the ground.

  Further, when the central portion of the curved plate 30 is recessed as compared with the peripheral portion, the height difference from the ground is increased, and the golf goal is less likely to compete upward. In this case, the long handle 20 can be lowered to cope with the concave portion of the GL.

On the contrary, when the center part of the curved plate 30 is a convex part compared with the peripheral part, it can respond to a convex part by making the use position of the long handle 20 high.
FIG. 5A illustrates a state in which a golf ball is collected using the curved plate 30 of the present invention. The golf ball touches the curved plate at the lowest level by pressing a long handle. It is a drawing that schematically shows how the ball that is raised up and gradually becomes two or three steps. FIG. 5 (B) is a diagram illustrating the case where a conventional ball rake is used. The golf ball is opposite to the adjacent golf ball by using dimples provided on the outer periphery as if using a gear. The direction in which the golf ball is rotated and the golf ball is not moved is described. From such a state, the golf balls do not rotate with each other when the reiki is pushed, so that the golf balls are eventually pushed and pushed, and the balls are vertically connected and manually pushed in the direction of collecting the balls. The ball does not roll and pushes the ball in the direction of collecting the ball in a non-rotating state, which is a work requiring force, and there is a limit to manual collecting (see FIG. 10B).
FIGS. 6 to 11 show a second embodiment of the golf ball reiki of the present invention, which is an embodiment using pipe rollers and a sled instead of the side rollers 50 and 52 and the center roller 60. Effective for collecting golf balls on the grass.
