JP5753421B2 - Hole post for ground golf - Google Patents

Description

  The present invention relates to a hole post that hits a ball hit by a player in ground golf and stops the ball.

  Ground golf is a game in which a ball is driven into a frame of a frame formed by a hole post to be stationary, and a pole for attaching a flag indicating a hole number is raised on the hole post above the frame. In the frame, a bell is suspended so that a ball hit in the frame hits and rings.

  The frame body of the hole post includes a circular outer frame located below, an inner frame provided above the outer frame and supported by a connecting frame, and a support plate provided at the center of the inner frame. In the conventional hole post, the lower end of the pole is applied to the upper surface of the support plate, the cylindrical bell is located on the lower surface of the support plate, and the bolt is inserted into the support plate from the inside of the bell to the upper side. The tip is screwed into the lower end of the pole to fix the pole to the support plate. In such a structure, when attaching the pole and bell to the support plate, it is necessary to rotate the pole many times while holding down the bolt, which is troublesome and cumbersome. There is known a hole post in which a pole can be detachably supported on a support plate of a frame (see, for example, Patent Document 1). However, the hole post described in Patent Document 1 is a type in which a male screw is formed on the outer peripheral surface of the lower end of the pole and this male screw is screwed into a female screw formed on the support plate, but the thickness of the support plate is thin. The length of the female screw is short and the screw thread is small. Therefore, the screw may be bitten, cannot be screwed in easily, or may be fixed uncertainly.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a ground golf hole post in which a pole can be easily and reliably attached to and detached from a support plate of a frame body.

  According to the present invention, the inner frame is formed above the outer frame via the connecting frame, the support plate for supporting the pole is provided at the center of the inner frame, and the bell is suspended below the support plate. A bolt having a non-rotating head at the lower end of the pole; and an insertion hole having a size that allows the head of the bolt to pass through the support plate; and an axial portion of the bolt following the insertion hole. The head of the bolt inserted through the insertion hole is provided with a catch member that forms a slide hole of a size that can be passed and that has an insertion groove that accommodates the head and can be held non-rotatably on the lower surface of the support plate. A hole post for ground golf is provided, in which the bolt can be tightened or loosened by rotating the pole in a state where it is held in the insertion groove of the catch member in a non-rotating state. The problem can be solved.

  Also, according to the present invention, in the hole post for ground golf, the insertion groove of the catch member is formed on the enlarged groove portion positioned outside so as to receive the head of the bolt inserted from the insertion hole, and the slide hole. An engaging groove portion located on the center side so that the head enters and engages when the bolt is moved along, and the bolt is moved between the enlarged groove portion and the engaging groove portion when the bolt is moved. A contact portion where the head hits is formed so that the direction of the head is aligned with the direction along the engaging groove, and a stopper for positioning the head of the bolt in the insertion hole is preferably provided at the edge of the insertion hole. The hole post for ground golf is provided.

  The present invention is configured as described above, and an inner frame is formed above the outer frame via a connecting frame, a support plate for supporting the pole is provided at the center of the inner frame, and a bell is hung below the support plate. A frame main body having a lower part is provided, and a bolt having a non-rotating head is screwed into the lower end of the pole, an insertion hole having a size that allows the head of the bolt to pass through the support plate, and the insertion hole. A catch member is formed that has a slide hole that is large enough to allow the shaft of the bolt to pass therethrough and that has an insertion groove on the lower surface of the support plate that houses the head and can be held in a non-rotatable manner. The pole is rotated while the head of the bolt is held in the insertion groove of the catch member in a non-rotating state so that the bolt can be tightened or loosened. Insert the bolt that has been fitted into the insertion hole of the support plate, move it along the slide hole, and rotate the pole while the bolt head stops rotating in the insertion groove. In this state, the pole is strongly screwed into the lower end of the pole, and the pole can be fixed on the support plate. If the pole is rotated in the reverse direction, the screw is loosened and the pole can be moved along the slide hole in the direction of the insertion hole, and the pole can be easily removed from the frame body.

  Further, the insertion groove is constituted by an enlarged groove portion and an engaging groove portion, and a contact portion where the head hits so as to align the direction of the head of the bolt in the direction along the engaging groove portion between the enlarged groove portion and the engaging groove portion. When the bolt is moved along the slide hole, the head of the bolt can be easily and reliably engaged with the engaging groove, and there is no need to worry about the direction of the head. Good sex. If a stopper is provided at the edge of the insertion hole so that the head of the bolt is positioned in the insertion hole, there is no possibility that the head of the bolt that has entered the insertion hole will be caught on the edge of the insertion hole when the pole is removed. The pole can be easily removed.

  1 to 4 show an embodiment of the present invention. A frame body 2 of a hole post 1 for ground golf includes an outer frame 3 formed in a substantially circular shape with a frame line, and an upper side from the outer frame 3. The inner frame 5 is supported by the rising connection frame 4 and is provided concentrically with the outer frame. A support plate 8 for supporting the pole 6 and the bell 7 is provided at the center of the inner frame 5. The pole 6 is composed of a plurality of members that can be connected, and a flag 9 indicating a hall number is provided above the pole 6.

  As shown in FIGS. 3 and 4, the bolt 10 is screwed to the block piece provided at the lower end of the pole 6, and is not completely tightened before being attached to the frame body, and is not tightened from the lower surface of the block piece. It is screwed with a gap of about several mm. As the bolt, a normal hexagon bolt, that is, a hexagonal head 11 for preventing rotation that engages a spanner (not shown) to rotate the bolt is formed at the tip of the shaft portion 12. Although a hexagonal bolt is used, a bolt having a head of various shapes, such as a quadrangle, an ellipse, etc., having a diameter larger than that of the shaft portion, may be used. Further, the length of the threaded portion is set so as not to easily fall off when the pole is loosened to carry the pole, and a retaining member can be provided at the inner end of the bolt if desired. (Not shown)

  As shown in FIG. 4, the support plate 8 is formed with an insertion hole 13 that is large enough to allow the head 11 of the bolt 10 to pass therethrough. The bolt shaft extends from the insertion hole 13 toward the center of the support plate 8. A slide hole 14 is provided continuously so as to allow the portion 12 to pass therethrough and extends to substantially the center of the support plate. Specifically, since the insertion hole 13 is formed in a substantially circular shape having an inner diameter that is slightly larger than the diagonal dimension of the head 11 of the hexagonal bolt, the bolt can be inserted and removed. When the shaft portion 12 is positioned, the head 11 hits the lower surface of the support plate 8, so that the bolt 10 cannot be removed from the support plate 8.

On the lower surface (back surface) of the support plate 8, a catch member 16 is formed in which an insertion groove 15 is formed to be accommodated between the lower surface of the support plate so that the head portion 11 of the bolt entering from the insertion hole 13 can be inserted. The insertion groove 15 is fixed to the support plate 8 by adhesion, welding or the like so as to be aligned in the same direction as the slide hole 14. The insertion groove 15 has an enlarged groove portion 17 positioned outside so as to receive the head portion 11 of the bolt 10 inserted from the insertion hole 13 and the head portion 11 when the bolt 10 is moved along the slide hole 14. Has an engaging groove portion 18 located on the center side so as to enter and engage. As shown in FIG. 5, the width of the enlarged groove portion 17 is wider than the diagonal length (interval) of the head 11 of the hexagonal bolt so that the head 11 can be easily inserted and removed. The width of the engagement groove 18 on the center side is narrower than the width of the expansion groove, and is the length of the opposite side of the head 11 of the hexagonal bolt so that the bolt head 11 can be received and slid without rotating. The width is slightly wider than (interval).

  The position of the change point of the groove width of the enlarged groove portion 17 and the engagement groove portion 18 is shifted as shown in FIG. 5, and when the change point located on the enlarged groove portion side moves the bolt toward the center, It is a contact part 19 where the corner of the part 11 hits. That is, as shown in FIG. 5, the gap between the grooves gradually becomes narrower toward the center with the change point as the boundary, and when the bolt is moved, as shown in FIG. When the corner of the head 11 hits the contact portion 19, the head 11 is rotated so that one side of the hexagon is in the direction along the engagement groove 18, and the direction of the bolt head 11 is the wall surface of the engagement groove 18. And the head portion 11 can be easily engaged with the engaging groove portion 18. In this way, since the hexagonal bolt head can be corrected to the correct position regardless of the position, it is not necessary to pay attention to the direction of the bolt during assembly. In the embodiment, both ends of the insertion groove are open, but only one side can be opened. The contact portion 19 is provided independently on the lower surface of the support plate separately from the groove. Also good.

  A stopper 20 can be provided at the edge of the insertion hole 13 of the support plate 8 so that the head 11 of the bolt 10 is preferably positioned in the insertion hole 13. Although this stopper 20 may be formed independently on the lower surface of the support plate 8, as shown in FIG. 7, one upper end of the connecting frame 4 is extended on the extension line of the slide hole 14, and the tip is inserted. The stopper 20 may be positioned so as to face the edge of the hole 13. In this way, when the bolt 10 is removed from the insertion hole 13, the head 11 is accommodated in the insertion hole 13, so that the bolt can be prevented from being caught in the insertion hole and can be easily taken out.

  The bell 7 is formed in a cylindrical shape as in the prior art, has a suspension hole 21 at the top, and a screw hole in which a mounting screw 22 inserted from below is formed in the catch member 16 as shown in FIG. It is suspended so as to be able to swing by being screwed into 23. After the bell 7 is attached, the attachment screw 22 may be fixed to the catch member 16 by adhesion, welding, or the like, and the bell may be suspended so as not to be removed. In this case, when stacking the frame main body, the frame main body 2 can be stacked without removing the bell 7 if the bell 7 can be tilted to the extent that the bell 7 is sufficiently large in the lateral direction to swing the neck.

  In order to use the hole post 1 at a ground golf course, the head 11 of the bolt 10 that is loosely screwed into the lower end of the pole 6 is inserted into the insertion hole 13 of the support plate 8, and along the slide hole 14 in the center direction. If the pole 6 is rotated by being moved, the bolt 10 is almost screwed into the pole 6, so that the bolt 6 can be tightened by a half turn and can be easily fixed to the frame body 2. The bell 7 may be suspended from the frame body 2 in advance. In this way, the pole setting operation can be completed in a short time, and the preparation time can be shortened. Further, if the pole is rotated in the direction opposite to the above, the bolt can be loosened and the pole can be easily removed from the frame body, and the tidying work can be greatly shortened. Since the conventional pole can be used as it is, the pole can be obtained economically.

  In the above embodiment, the catch member formed separately from the support plate is fixed to the support plate. However, the support plate and the catch member may be provided integrally. For example, as shown in FIGS. 8 and 9, a frame piece 24 that is bent downward is formed on a part of the support plate 8 by pressing along the slide hole 14, and the space between the frame pieces 24 is inserted. The catch member 16 may be the engaging groove portion 18 of the groove 15. In this case, one end portion of the frame piece may be provided so as to be shifted from the end portion of the other frame piece, and the outer end portion may be a contact portion 19 with which the head portion 11 of the bolt 10 abuts. Note that the bracket 25 may be fixed to the lower surface of the support plate 8 by welding or the like, and the bell 7 may be suspended so as to swing on the support pin 26 fixed to the bracket 25.
