Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a gateball stick, and more particularly to a gateball stick whose shaft is foldable.

<Prior Art> In a conventional gateball stick, the head and the shaft can be separated so that they are convenient to carry.

<Problems to be Solved by the Invention> However, if the head and the shaft are separated from each other, the size becomes compact, and although it is convenient, either the head or the shaft may be lost.

The present invention was devised in view of the above circumstances, and an object thereof is to provide a gateball stick in which the shaft can be folded for convenient carrying.

<Means for Solving Problems> A gateball stick according to the present invention is a head mounting member, a head mounting member, a large-diameter portion into which the head mounting member is fitted, and a small-diameter portion having a female thread around the head mounting member. A head having a hole, a shaft mounting metal fitting axially supported by the head mounting metal fitting, a shaft having the shaft mounting metal fitting attached to a tip, and a head mounting hole that is externally fitted to the shaft mounting metal fitting. A fixing ring having a tip inserted between the large-diameter portion and the head mounting bracket, and a click mechanism for fixing the head and the shaft in a use position and a non-use position. A bottom portion having a diameter equal to that of the large diameter portion, and an upper portion which is connected to the bottom portion and has a small diameter by a dimension corresponding to the thickness dimension of the tip of the fixing ring; The click mechanism has a through-hole penetrating the center of the bottom and a forked portion connected to the upper part, and the click mechanism has a pressure spring internally provided in the through-hole and a shaft mounting by the pressure spring. It has a sphere that is elastically urged in the direction of the metal fitting, a click groove that is provided in the shaft mounting metal fitting and that locks the sphere, and a bolt that is screwed into the small diameter portion and supports the pressure spring. The click groove has a first groove in which the sphere is locked when the shaft is in the use position, and a second groove in which the sphere is locked when the shaft is in the non-use position. By changing the screwing condition with the small diameter portion, the elastic force applied to the sphere by the pressure spring is changed.

<Operation> When using a gate ball stick, extend the shaft and insert the tip of the fixing ring into the head mounting hole.

When not in use, that is, when the shaft is folded, the tip of the fixing ring is pulled out from the head mounting hole to rotate the shaft.

<Example> Hereinafter, an example according to the present invention will be described with reference to the drawings.

The gate ball stick according to the present invention includes a shaft 10 that a user grips, a head 20 that hits a ball, and a shaft mounting bracket 30 that is mounted on the tip of the shaft 10.
A head mounting bracket 40 fitted in a mounting hole 21 provided in the head 20, a fixing ring 50 for fixing the extended shaft 10, and a use position and a non-use position of the shaft 10 and the head 20. It has a click mechanism 60 for fixing.

The shaft 10 is, for example, a hollow rod made of carbon fiber or the like.

The head 20 is formed by impregnating a laminated resin or the like with synthetic resin into a cylindrical shape, and a head mounting hole 21 is formed on the side surface thereof. The head mounting hole 21 has a large diameter portion 211 formed on the side surface, a bolt hole 213 formed on the side opposite to the side on which the large diameter portion 211 is formed, and a large diameter portion 211.
And a small diameter portion 212 that communicates with the bolt hole 213. The diameter is set in the order of large diameter portion 211> bolt hole 213> small diameter portion 212. A female thread 212a corresponding to a male thread 632 formed on a bolt 63 described later is formed on the inner surface of the small diameter portion 212, and the bolt hole 213 is set to have a diameter corresponding to the head of the bolt 63. That is, the bolt 63 is slidable with respect to the through hole 41 with the male screw 632 and the female screw 212a.

An insertion hole 31 into which the tip of the shaft 10 is inserted and fixed is formed in the shaft core of the shaft mounting member 30, and a tongue piece 32 having a click groove 322 is formed at the tip thereof. The tongue piece 32 is set to a size corresponding to a forked portion 42 of a head mounting member 40, which will be described later, and a corner is provided with a radius so that the shaft mounting member 30 can smoothly rotate. In addition, an opening 321 is formed at the center of the tongue piece 32.
Has been established.

The head mounting member 40 is fitted into the large-diameter portion 211 of the head mounting hole 21, and the through hole 41 is opened in the axial center of the head mounting hole 21, and the forked portion 42 is projected to the outside of the head 20. It is configured. The through hole 41 opens between the forked portions 42. In this head mounting bracket 40, the bottom portion 43 has the large-diameter portion 21.
The diameter is equal to 1, while the upper portion 44 is slightly smaller than the bottom portion 43. Therefore, the head mounting hole
When the head mounting member 40 is fitted into the head 21, a slight gap is left between the upper portion 44 and the head mounting hole 21, but the head mounting member 40 can be fixed by the bottom portion 43. A round hole 421 corresponding to the opening 321 is formed in the bifurcated portion 42. The through hole 41 has substantially the same diameter as the small diameter portion 212. The tongue piece 32 is positioned between the forked portions 42, and the pin 70 is fixed to the opening 321 and the round hole 421. In this state, the shaft mounting member 30 is rotatably supported with respect to the head mounting member 40, and further, the shaft 10 is rotatably supported with respect to the head 20. (See Figure 2).

The fixing ring 50 is fitted onto the shaft 10, and the tip 51 of the fixing ring 50 is attached to the large-diameter portion 211 of the head mounting hole 21 and the head mounting hole 2.
The shaft 10 is fixed to the head 20 by inserting the shaft 10 into the gap between the upper part 44 and the upper part 44. The fixing ring 50 has a substantially cylindrical shape, and the tip end 51 thereof is slightly narrowed inward from that of the other portions. This is because the depth at which the fixing ring 50 is inserted into the large diameter portion 211 is always constant. The surface of the fixing ring 50 is formed with knurls 52 for preventing slippage.

The click mechanism 60 is a pressure spring installed in the through hole 41.

And the click groove 322 and a bolt 63 for supporting the pressure spring 61. It should be noted that only the click groove 322 is provided on the tongue piece 32, and the first groove 322a into which the sphere 62 fits when the shaft 10 is extended (when used) and when the shaft 10 is folded (when not used). And a second groove 322b into which the sphere 62 is fitted. The pressure spring 61 is fitted in a protrusion 631 provided at the tip of a bolt 63 inserted from the small diameter portion 212, and a sphere 62 is located at the tip of the pressure spring 61. The bolt 63 has a small diameter portion 212.
The spherical body 62 is always elastically biased by the pressure spring 61 in the direction of arrow A shown in FIG.
As mentioned above, the shaft mounting bracket 30 and the head mounting bracket 40
Is rotatably supported by a pin 70, so that the spherical body 62 is always in contact with the tongue piece 32.

Next, the operation of the gate ball stick according to the present invention will be described.

When using a gateball stick, use the shaft
Extend 10. That is, the shaft 10 is rotated 90 ° in the direction opposite to the arrow B, and the tip 51 of the fixing ring 50 is attached to the head mounting hole 21.
Inserted in the large diameter portion 211 of. At this time, the spherical body 62 has the first groove 322.
It fits into a (see FIGS. 1 and 4), and the click feeling makes it clear that the shaft 10 has reached the correct position.

When not in use, that is, when the shaft 10 is folded, the tip 51 of the fixing ring 50 is pulled out from the large diameter portion 211 and the shaft 10 is rotated in the direction of arrow B. At this time, the spherical body 62 is pushed down into the through hole 41 while resisting the elastic force of the pressure spring 61. Then, the shaft 10 is fitted into the second groove 322b and fixed in the folded state (see FIG. 3). In this case as well, the click feeling is the same as when the shaft 10 is extended.

The click feeling can be adjusted by the bolt 63.

<Advantages of the Invention> According to the gateball stick of the present invention, the shaft can be folded to make the whole compact without separating the shaft and the head, which is very convenient for carrying. , Never lose the shaft or head.

Further, by adjusting the screwing condition of the bolt with the small diameter portion, the elastic force applied to the spherical body by the pressure spring can be appropriately changed by sliding through the through hole of the head mounting bracket. You can adjust the strength of the shaft folding force according to your preference.

Further, when not in use, the shaft is held by the click mechanism, that is, the sphere and the second groove of the click groove, and thus maintains the folded state. Therefore, the gateball stick according to the present invention has an advantage that it is very convenient to carry. Further, at the time of use, the tip of the fixing ring is inserted between the large-diameter portion of the head mounting hole and the head mounting member, so that the fixing ring, and thus the shaft, is firmly fixed to the head. Therefore, since the shaft does not wobble during use, an accurate impact can be performed.
