Description

Partial Soul Device of Park Golf Head}

The present invention relates to a partial sole device for a park golf head in which a part of the soul that is easily worn in the park golf head is made up of partial sole.

Park golf is currently one of the most popular sports. It is a sport that anyone can enjoy easily and simply by hitting the butter of golf while stepping on natural grass with a club and a ball in a city park or river. The rules of golf are applied. .

For safety reasons, the park golf balls used in park golf are larger than regular golf balls and are made of soft plastic, with a diameter of 6 cm and a weight of 80 to 95 g. The park golf balls have a length of 86 cm or less from the tee shot to the putting. Use only one light, half-moon shaped club.

The park golf club used in such park golf usually has a head made of solid wood, weighs about 380g, a shaft is connected to the top of the head, and a club is attached to the bottom of the head to reinforce the area that comes into contact with the ground or mat. It is common for a sole made of metal to be combined, with a crown on the top, and a faceplate for hitting the ball on the front.

In the conventional method of combining the head body and the soul, it was common to connect the soul (B) to the bottom of the head body (A) with a countersunk bolt (C), as shown in Figure 1.

However, in the past, when a park golf club was used for a long period of time, the front lower part of the soul was intensively worn, and this caused the inconvenience of replacing the soul, so there was a problem that most park golf heads had to be discarded.

below, Figure 2 inside Figure 3 The present invention will be described with reference to the following.

As shown, the present invention is characterized by forming a partial sole (10) by cutting a portion of the sole (B), which is intensively worn in the head of the park golf club, from the sole (B).

More specifically, the present invention, as shown, includes a partial sole (10) formed by cutting a portion of the sole (B) that is intensively worn in the park golf head from the sole (B); The partial soul (10) can be coupled to the bottom of the head body (A) with a countersunk bolt (C) as in the prior art.

In this way, as described in the effect of the invention, a part of the sole (B) that is intensively worn in the park golf head is cut from the sole (B) to form the partial sole (10), so that the partial sole (10) is formed according to long-term use. When it wears out, it can be replaced, which has the effect of allowing the park golf head to be used for a long time.

below, Figure 4 inside Figure 5 The present invention will be described with reference to the following.

As shown, in the present invention, instead of combining the partial soul 10 with a countersunk bolt (C), the fastener 20 is connected through a fastener 20 to connect from the upper surface of the head body (A) to the upper surface of the partial sole 10. can do.

More specifically, the present invention, as shown, includes a partial sole (10) formed by cutting a portion of the sole (B) that is intensively worn in the park golf head from the sole (B); A nut support (30) formed on the upper surface of the partial sole (10); a nut support insertion groove (31) formed on the bottom of the head body (A) to allow the nut support (30) to be inserted; A fastener insertion groove (21) formed to allow the fastener (20) to be inserted into the upper surface of the head body (A); It may be composed of a fastener 20 that is inserted from the upper fastener insertion groove 21 of the head body (A) and couples the nut support 30 of the partial sole 10.

In the above configuration, the soul (B) and the head body (A) are joined by employing a countersunk bolt (C) in the conventional manner as shown, and the partial soul (10) is attached to the bottom of the head body (A). Position (10) and position the partial sole (10) on the bottom of the head body (A) so that the nut support (30) of the partial sole (10) is inserted into the nut support insertion groove (31) on the bottom of the head body (A). Then, the fastener 20 can be inserted into the fastener insertion groove 21 on the upper surface of the head body (A) to fasten the nut support 30 of the partial soul 10.

In the above, the nut support 31 can be manufactured separately from the partial sole 10 and joined by welding, or manufactured integrally with the partial sole 10 through die casting, and when high-strength synthetic resin is used instead of metal, it can be manufactured by injection molding. It can be manufactured as one piece, and in this case, the threaded part of the nut support 30 can be formed through processing, and the nut support insertion groove 31 and the fastener insertion groove 21 of the head body (A) are the head body ( It can be formed through processing after manufacturing A).

Although not explained in detail in the background technology, the conventional way to combine the head body and the soul is to form a fastening hole on the bottom of the head body (A) as shown in Figure 1, and then place the soul (B) on the bottom of the head body (A). After going through the pretreatment process of applying adhesive to the threaded part of the countersunk bolt (C) and tightening the fastening hole one-time, the head of the countersunk bolt that protrudes from the surface of the sole is polished with a grinder because the surface of the sole is curved, and then the entire surface of the sole is ground. It was common to finish through a matching post-processing process.

However, the conventional coupling method is as described above when some fasteners are dislodged due to impact during use of the park golf club, the sole is separated as a result, or the bottom of the sole is intensively worn and the sole needs to be replaced. Likewise, since the soul went through a pretreatment process of one-time fastening with adhesive and countersunk bolts and was then finished with a postprocessing process of surface treatment with a grinder, there is a limit to the primary expansion of the fastening hole when the above-mentioned situation occurs, and 2 There was a problem in that it was difficult to replace the fasteners and soles because they had to go through the above-described pre- and post-processing processes again, and because of this, most people just discarded the Park Golf Club.

However, if the coupling method as described above is used, there is no need to expand the fastening hole as in the past when replacing the partial sole (10), and the pretreatment process that requires fastening by applying adhesive and the countersunk bolt (C) after coupling This has the effect of eliminating the need for a post-processing process of machining the entire surface of the head and soul (B) with a grinder, and because the partial soul (10) and the head body (A) are vertically fastened through the fastener (20), Compared to this, the coupling strength is excellent, so the fastener (20) and the partial soul (10) are not easily separated from the head body (A). In particular, the partial soul (10) can be replaced with another partial soul (10) depending on the experience, mood of the day, etc. ) is effective in that it can be easily replaced and used.

below, Figure 6 inside Figure 7 The present invention will be described with reference to the following.

As shown, the present invention includes a locking piece 40 protruding rearward from the middle upper surface at the rear of the partial sole 10; It may include a locking piece insertion groove 41 formed on the bottom of the head body (A) into which the locking piece 40 is inserted.

In the above configuration, the locking piece 40 of the partial sole 10 is inserted through the locking piece insertion groove 41 of the head body A so as to span the front upper surface of the soul B, and then is used as a fastener 20. It was made to be concluded.

In this way, not only is it easy to couple the partial soul (10), but the coupling force between the soul (B) and the partial soul (10) is increased by pressing the partial soul (10) from the soul (B) through the locking piece (40). There is an improving effect.

below, Figure 8 inside Figure 9 The present invention will be described with reference to the following.

As shown, the present invention may include penetratingly coupling the fastener 20 so as to extend from the upper surface of the head body (A) of the park golf club to the upper surface of the soul (B).

That is, the soul (B) may be combined in the same manner as the partial soul (10).

This has the effect of eliminating the need for the pretreatment process of applying adhesive and fastening the countersunk bolt one-time as in the past, and the postprocessing process of processing the entire surface of the head and sole (B) of the countersunk bolt with a grinder, thereby eliminating the need for the park. It has the effect of shortening the overall manufacturing time of the golf head, and since the fastener 20 is vertically fastened, the bonding force is excellent compared to the conventional one, so the fastener 20 and the sole (B) are easily separated from the head body (A). This has the effect of preventing wear and tear, and Soul (B) can be easily replaced depending on whether the entire surface of Soul (B) is worn out, fatigue, mood, etc. that day.

below, Figure 10 inside Figure 11 The present invention will be described with reference to the following.

As shown, the present invention manufactures the crown portion of the head body (A) in the form of a shell, and then creates a partial crown (50) coupled to the head body (A) to cover the upper fastener (20) of the head body (A). ); may include.

Specifically, the partial crown 50 is manufactured in the form of a shell as shown, and can be manufactured by die casting if it is metal or injection if it is synthetic resin. As shown, the upper surface of the head body (A) A partial crown insertion groove (51) can be formed in the part covered by the partial crown (50) and then combined with the head body (A), and the connection is achieved by a nut support on the upper surface of the head body (A) as shown. After inserting and fixing (30), it can be coupled in the same way as the coupling method of the soul (B) and the head body (A), and the nut support (30) is embedded in the head body (A). It can be buried by forming a buried groove and then inserting the nut support 30 into the buried hole.

Typically, the head body (A) is made of solid wood, and a considerable amount of time is spent on the wood breaking-in process, which involves repeated watering and drying to prevent deformation and cracking of the wood. In particular, the crown portion is painted and dried several times. The repeated painting process takes a considerable amount of time.

However, as described above, if the crown part of the head body (A) is used as a partial crown 50, the process of breaking in the wood of the head body (A) is simplified and the crown failure process becomes unnecessary, which has the effect of making it unnecessary. There is an effect of shortening the overall manufacturing time of the park golf head, and in particular, when the partial crown 50 is adopted in the present invention, the fastener 20 of the head body (A) is obscured and the appearance is improved. In addition, it has the effect of being able to be easily replaced with a different partial crown (50) at any time depending on the crown's scratches or wear due to long-term use, the mood of the day, etc.
