Description

TECHNICAL FIELD

The present invention relates to a golf club including a putter that can be tailored to a user using various kinds of blocks.

BACKGROUND ART

The present invention provides a golf club including a putter that can be tailored to a user using various kinds of blocks. In most cases, golf clubs are often used as ready-made items, but since a swing may vary slightly depending on the user's swing characteristics, habit, physique, body shape, etc., when the career is long, the golf club may be fitted little by little according to the characteristics of the user's swing. Further, in the case of a putter, the lie angle may be adjusted (Korean Utility Model Application No. 20-2006-0016311) or a weight adjuster may be provided (Korean Utility Model Application No. 20-2006-0015077).
However, such putters are not used often, because the adjustment range is limited or the adjustment method is very difficult. In other words, Korean Utility Model Application No. 20-2006-0015077 is problematic in that there are many cases where there is not much difference in actual use by just adding a few weights, and the weights may be separated, and further, the process of disassembling and assembling to adjust the lie angle is very difficult.

DESCRIPTION OF DRAWINGS

FIGS. 1 to 8 are views showing an embodiment of the present invention.

BEST MODE

Provided is a golf club that can be tailored to a user using various kinds of blocks, the golf club being configured such that a block 13 is coupled to the golf club, the block 13 including a recessed groove 14 provided on an upper surface thereof by being recessed inward and an insertion protrusion 12 provided on a lower surface thereof by protruding downward, wherein between one block 13 and another block 13, the recessed groove 14 and the insertion protrusion 12 are couplable to each other, and when at least two blocks 13 are coupled to each other, the recessed groove of a block 13 and the insertion protrusion 12 of an adjacent block 13 are engaged with each other, and then a screw is fitted into the blocks from the recessed groove to couple the at least two blocks 13.

MODE FOR INVENTION

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. A block-type golf club according to the present invention may be applied to a putter, a driver, and an iron, but for convenience of explanation, the embodiment is limited to a putter. FIGS. 1 to 4 are views showing an embodiment of the present invention. A putter according to the present invention has a shape similar to that of a block to be assembled by children, so that the putter can be constituted by fitting the blocks in a primary way.
In other words, the block is formed with a convex member 11 on an upper surface or a side surface thereof, and is formed with an insertion protrusion 12 on a lower surface thereof into which the convex member 11 is inserted, so that one's own putter can be made by fitting multiple blocks. In particular, by varying the color of the block 13, it is possible to represent one's own personality by placing and combining blocks of various colors.
The convex member 11 shown in FIGS. 1 to 4 may be formed by protruding from the block 13 or may be formed by a screw head 21 protruding when a screw is inserted into the block 13. The formation of the convex member 11 by the screw head 21 will be described with reference to FIG. 7.
As shown in FIGS. 1 to 4, a plurality of convex members 11 may be formed in one block 13 and the number of convex members 11 formed by the screw head 21 may be adjusted as necessary.
The blocks 13 can be added or assembled to create block assemblies with various shapes and centers of gravity, wherein the insertion protrusion 12 is formed at the lower end of the block 13 and the recessed groove 14 is formed at the upper end of the block 13 such that when the block 13 and another block 13 are engaged, the insertion protrusion 12 is inserted into the recessed groove 14, and the engagement is completed by inserting the screw.
Since each block is different in weight and center of gravity, when each block is coupled to a golf club or a putter, the feeling of each person's swing may change. Conventionally, since the weight is simply changed by simply placing a few weights, it is impossible to change the center of gravity even though the weight felt during the swing may be changed. However, according to the present invention, the center of gravity can also be changed according to the user's convenience. In particular, changing the center of gravity is not about adding weight, rather it is similar to completely changing the club itself, so the user's feeling of swing changes greatly and one club can be used differently depending on the situation.
However, when the block-type member is inserted, if only the insertion protrusion 12 and the recessed groove 14 are engaged, the block may be separated due to the impact according to the swing, and thus, in the present invention, a portion corresponding to the convex member 11 of the block is configured using a screw. Conventionally, since weights are weighted by using magnets, the magnets are often separated due to impact, so it is difficult to apply to drivers or irons with large swing. However, in the present invention, it is possible to apply to an iron or a driver since coupling is made by a screw.
In other words, if the coupling is made only by the convex member 11 being inserted into the insertion protrusion 12, the coupling may be easily disassembled by the impact against a golf ball, and thus, the coupling is made by a screw.
However, as shown in FIG. 5, in the screw engagement, if the threads formed on the inside of the block are not continuous in the upper block and the lower block when the coupling is made by using the screw inserted between two or more blocks 13, the threads inside the block or the screw may be broken during the process of turning the screw. However, adjusting the threads of two blocks to be contiguous requires very high precision and excessively increases the price of the block.
In the present invention, to solve the above problem, there is provided a screw having a threaded region 23 with threads and a flat region 24 without threads.
Further, the internal threads 22 may be formed at a part of a hole formed inside the block 13 except opposite ends thereof, into which the screw is inserted, but not be formed at the entire of the hole, or may be formed at a lower-most block 13.
Accordingly, the problem that the threads should be continuous is solved because the internal threads 22 are not formed in the areas where the two blocks face each other and the threads of the screw pass by the areas.
Alternatively, the screw may be formed with at least two threaded regions 23. In other words, the screw used to connect the two blocks and the screw used to connect the three blocks may be provided separately, and each screw is formed with threads, wherein the threads are not formed over the entire body of the screw but the flat region 24 without threads is intermittently formed in the screw, and the threaded region 23 with threads is formed by the number of blocks to be coupled, such that the threaded region 23 of the screw and the internal threads 22 inside the block are engaged when the screw is inserted.
If there are two blocks to be coupled, the threads may be formed by being divided into two parts in the body of the screw, and if there are three blocks to be coupled, the threads may be formed by being divided into three parts in the body of the screw.
As shown in FIG. 7, when the screw is inserted, facing areas are defined between the convex member 11 of the block and the insertion protrusion 12, and the threads are difficult to be continuous between the facing areas, so it is hard to fit the screw. However, in the present invention, threads are not formed at a part of the screw where the blocks face each other such that the screw passes by the facing areas, and threads are not formed at the facing areas inside the block such that the screw passes by the facing areas. Accordingly, the threads inside the block are formed to protrude from the inside of the block toward the center, and the threads of the screw are formed to protrude around the body of the screw. In other words, it is possible to allow the portion of the screw without threads to pass by without engagement.
FIG. 6 shows another embodiment, wherein there are provided screws of different lengths depending on the number of blocks to be coupled, and the screw is formed with the threaded region 23 only at an end thereof such that the screw head 21 serves as the convex member 11 when the screw is inserted, and multiple blocks are allowed to be coupled by the screw. Since the block 13 is formed with multiple recessed grooves 14 and insertion protrusions 12, blocks can be tightly connected by multiple screws.
Further, it is possible to reassemble multiple block assemblies by using the insertion protrusion 12 that is large enough to accommodate the screw head 21.
FIG. 8 shows a shape in which a plurality of blocks 13 and a screw are engaged without damaging threads.
Although only one threaded region 22 is shown in the drawing, a plurality of threaded regions 22 may be formed as needed or as the number of blocks increases.
FIG. 4 shows connection of a rear surface of a putter in the case of a putter, wherein the rear surface of the putter engages an impact plate for impact with a golf ball, and the impact plate may be coupled to the side surface of the block by using a screw.
