The present invention relates to a device for golf swing correction, and in particular to a device for golf swing correction which can be selectively engaged at a head of a golf club and makes it possible for a user himself to check whether or not a user's swing is performed along an accurate track with the aid of a laser beam coming from a laser module.

BACKGROUND ART

A conventional device for golf swing correction is generally designed to focus on a function of indicating a swing line, and it is engaged at a shaft of a golf club.
The above device is characterized in that a laser beam coming from a laser module of a swing line indicator engaged at a shaft of a golf club goes straight alongside a shaft and indicates a target point.
The Korean patent registration number 10-0674029 discloses the construction of an apparatus for indicating swing and put line for golf.
The above conventional apparatus for indicating swing and put line for golf is designed to engage at a shaft, not a face surface when in actual use. The indicator is installed in such a way that the distance between the indicator and a laser point is spaced apart one meter maximally. The conventional indicator has a disadvantage in that an error value range might be large due to a viewing difference between users left and right eyes.
In addition, when a user multiple times rotates a laser module, a friction force between an outer surface of a rotation ball and an inner surface of a groove decreases, thus loosening their engagements.

The laser module 100 has a function of generating and emitting a laser beam. Since the basic operation principle of the laser module 100 is known in the art, the descriptions on the generation and emission principles of the laser beam will be omitted.
The laser module 100 comprises a body part 110 formed in a cylindrical shape on the whole, an engaging part 120 inserted into the clamping part 300, a switch 130 turning on/off the generation and emission of the laser beam, and a guide protrusion 140 guiding the engagement of the laser module 100.
The body part 110 is formed in a cylindrical shape, with batteries and electronic parts being disposed in the interior of the body part 110.
The engaging part 120 is provided at a lower side of the body part 110 and has an outer diameter smaller than that of the body part 110, from which a laser beam is generated and travels to the outside via a lens (not shown of a lower side. In other words, the laser beam coming from the lower side of the laser module 100 travels outward and indicates a bottom surface or a target thing.
The switch 130 is protruded upwardly from an upper side of the body part 110. So, when a user pushes once the switch 130, laser beam is generated, and emits, and when a user pushes once more the switch 130, the laser beam is turned off.
The guide protrusion 140 is outwardly protruded from an outer surface of the engaging part 120. The guide protrusion 140 is formed to have a certain length in an upward and downward direction along the longitudinal direction of the laser module 100.
The guide protrusion 140 is provided at least one. In other words, it might be formed at a front side and a rear side or at a left side and a right side of the engaging part 120. The guide protrusion 140 is inserted into a guide groove 312 a which will be described below and serves to guide the laser module 100 to be engaged in place.
The laser beam (laser point) emitted from the laser module 100 might be formed in a “+” shape, a “−”shape or a “.” shape.
The support part 200 serves to support the laser module 100. One end portion of the support part 200 is detachably engaged at a face (F) surface of the golf club (including putter). In other words, each golf club is generally formed of a shaft (S) and a head (H). The lower end portion of the support part 200 is fixed to a face (F) surface of the head (H).
The support part 200 comprises an arch shaped engaging member 210 which comes into close contact with the face (F) surface of the golf club, and a support member 220 supporting the clamping part 300.
The engaging member 210 is rounded to have an arch shape as shown in the drawings. At both ends of the engaging member 210 are disposed the close engaging member 400 in a pair. The engaging member 210 might be formed in a stepped shape (when viewing from the above). The reasons for forming the engaging member 210 in a stepped shape are to prevent any interference with the shaft (S) when the support part 200 comes into close contact with the face (F) surface of the putter.
As shown therein, the support member 220 is extended upward from the engaging member 210. In other words, it protrudes vertically from the back of the engaging member 210 in an upward direction, thus supporting the clamping part 300.
The clamping part 300 is provided atop the support part 200. In other words, the clamping part 300 is rotatably installed at the support part 200. The laser module 100 is detachably fixed at the clamping part 300. As the clamping part 300 rotates, the laser module 100 rotates, so the direction of the laser beam coming from the laser module 100 can change.
The clamping part 300 comprises a fixing member 310 fixing the laser module 100, and an engaging member 320 facilitating the laser module 100 to be supported by means of the support part 200.

The fixing part 312 is formed to have a C-shaped cross section (when viewing from the above) and surrounds the engaging part 120. The fixing part 312 is made from a plastic material or something and is formed to have a certain elastic force from its shape. In other words, it is formed in a C-shape with its opening being able to be open by an external force.
At least one guide groove 312 a accommodating the guide protrusion 140 is formed at an inner surface of the fixing part 312. A guide groove 312 a selectively accommodating the guide protrusion 140, mentioned earlier, is formed at upper and lower sides.
In more details, a guide groove 312 a corresponding to the guide protrusion 140, respectively, is formed at the rear side and left and right sides of the inner surface of the fixing part 312.
The fixing part 312 is formed to surround more than half the outer surface of the engaging part 120 of the laser module 100 on the whole. At both left and right sides of the front end of the fixing part 312 are provided an escape prevention protrusion 312 b supporting for the laser module 100 inserted at an inner side of the fixing part 312 not to escape as shown in the drawings.
The insertion part 314 is formed in a thin rod shape and is installed to pass through the upper side of the support member 220.
The engaging part 316 is extended from the left side (FIG. 2) of the insertion part 314 and is formed of a mane thread. The engaging part 316 is thread engaged with the engaging portion 322 which will be described later.

Next, the laser module 100 is inserted into the fixing member 310 of the clamping part 300. The opening of the fixing part 312 is open, and the engaging part 120 of the laser module 100 is inserted. As the laser module 100 rotates, the guide protrusion 140 is inserted into the guide groove 312 a of the fixing part 312, so the laser module 100 can be positioned in place.
Since the close engaging member 400 is already provided at the lower side of the support part 200, the lower side of the support part 200 is forced to come into close contact with the face (F) surface of the golf club (putter) as show in FIG. 3. The lower side of the support part 200 comes into close contact with the face (F) surface of the putter by a magnetic force of the close engaging member 400.
When the device according to the present invention is engaged at the golf club (putter), a user turns on the laser switch 130 and swings a golf club as usual. Since the laser beam coming from the laser module 100 emits alongside the shaft (S) from the bottom surface (P), so the user can accurately recognize the swing track.
