BACKGROUND OF THE INVENTION Field of the Invention [0002] The present invention relates to an indoor golf course equipment, and more particularly, to an improvement of a screen golf course screen fabric capable of enhancing durability and screen sharpness of a screen fabric constituting a video screen.

As golf has become popular these days, many people are looking for golf courses.

Among the golf driving range, a screen golf course installed indoors is equipped with a golf simulation system for playing golf in a real golf course. The golf simulation system includes a flight area for hitting a golf ball, a flight locus sensing means for sensing a flight locus, such as the direction and speed of a hit golf ball, a video screen for displaying a three-dimensional image of a golf course output by the projector, And a control unit for causing the projector to output a video signal for advancing a three-dimensional image of the golf course according to the trajectory detected by the trajectory sensing unit.

When the golfer hits the golf ball on the screen golf course implemented in such a system, the hit golf ball falls off after aligning the front screen, but the flight path of the golf ball in the course of reaching the screen is sensed by the flight sensing means and applied to the control unit The control unit calculates the flying distance and the stopping point of the golf ball using the applied flight trajectory information, and then displays the three-dimensional image proceeding along the flight path on the screen through the projector.

Practice on a screen golf course can help you train with the same visual sense as playing a golf game on a real golf course.

Since the screen fabric of such a screen golf club is fit to a large number of hit golf balls, the lifetime of the screen golf club is not long, and it is desired to have a fabric structure having durability.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Screen cloth for screen golf should be woven so that the breakage of the fabric occurs as late as possible even with continuous blow of the golf ball and the flatness of the fabric is good so that the image on the projector can be clearly formed. It is recognized.

Fig. 1 shows a general screen golf course image screen 2, which is formed of a screen fabric 4 on which an image is formed and a frame portion 6 sewn on the screen fabric 4.

Normally, the standard size of the screen screen 2 for the screen golf course should be 5 x 3 meters. Therefore, in general, the fabric must be expanded and sewed to match the size of the screen fabric with a fabric width of 1.5 meters, so that the seam portion becomes an area that is concentratedly hit by the golf ball. It also makes it very bad.

In order to solve this problem, a wide fabric having a fabric width of 3 meters is mainly used as the screen fabric 4 of the image screen 2. In this case, the slope (p Are arranged in the left and right direction of the image screen 2 and the weft w of the screen fabric 4 is arranged in the vertical direction of the image screen 2. [

The woven fabric is produced by bundling the warp yarn (w) through a warp beam, which is a bundle of warp yarns (p), which are generally wound around a plurality of yarns at one time, As shown in FIG. 1, the weft density coefficient is relatively lower than the slope density coefficient in a universal manner in which weaving cost is increased.

The inventors of the present invention have confirmed that the fabric structure of the thread density coefficient facilitates partial rupture of the screen fabric 4 when striking the golf ball.

More specifically, as compared with the weft yarn w in which the warp p arranged horizontally in the screen fabric 4 constituting the image screen 2 is arranged up and down, exposure to the outside is much larger. On the image screen 2, most of the inclinations (p) are exposed. The exposure of the slopes p arranged in the left and right direction causes rotational friction in a direction perpendicular to the slopes p when the golfer hits the spinning golf ball in the vertical direction, And is partially torn in the longitudinal direction on the screen fabric 2.

Accordingly, the present inventors have found that when a weft density coefficient of a screen fabric constituting an image screen is increased and a weft is exposed to a large surface of a fabric, a fabric is formed so that the warp (p) It was confirmed that the golf ball spinning in the direction minimizes the direct contact with the warp p and minimizes the friction angle with the weft w to improve the durability of the screen fabric when the warp direction durability is enhanced. That is, it is confirmed that the bursting property of the inclination (p) of the screen fabric can be minimized.

Accordingly, in the present invention, the weft density coefficient constituting the screen fabric for screen golf is set to be equal to or greater than the slope density coefficient. Preferably, the weft density coefficient constituting the screen fabric is made larger than the slope density coefficient.

The density coefficient (K) has a relationship represented by the following equation (1).

Here, K is a density coefficient, density (number / inch) indicates the number of original copies arranged in one inch, and number (Nm) indicates the thickness of the yarn.

The density coefficient (K) is a numerical value that determines the density of the number of original copies arranged in the unit interval (1 inch) as an absolute value with respect to the thread thickness. As the density coefficient value is high, . Even if the yarns having different thicknesses (number of yarns) are put into the same density, the density coefficient is changed, and even if the same density coefficient is applied, the density number varies depending on the yarn thickness.

The warp yarn density coefficient according to an embodiment of the present invention is formed such that the weft density coefficient is greater than or equal to the warp density coefficient, and the warp density coefficient is in the range of 10 to 20 and the weft density coefficient is in the range of 12 to 20. Preferably, the weft density coefficient constituting the screen fabric is larger than the slope density coefficient.

Fig. 7 is a view for explaining the change of the warp yarn density coefficient and the state of surface inclination (p). In FIG. 7A, the inclination density coefficient is larger than the weft density coefficient, and the surface inclination p is increased. In FIG. 7B, according to the embodiment of the present invention, If the coefficient is larger, the surface inclination of the inclination becomes smaller. In Fig. 7, reference character 'w' is the upper side.

FIG. 2 shows a schematic configuration of an image screen 12 for a screen golf course according to an embodiment of the present invention. As shown in FIG. 7 (b), the weft density coefficient of the screen cloth 14 is set to a slope density coefficient (W) of the warp yarns (p, w) constituting the screen fabric (14) is formed to be denser than the warp yarns (p).

In addition, according to the present invention, not only the durability of the screen fabric 14 constituting the image screen 12, but also the smoothness of the screen are improved to enhance the clarity of the screen of the image screen 12.

In order to improve the smoothness in consideration of the durability of the screen fabric 14, the present invention considers the organization of the screen fabric 14. The smoothness becomes higher as the surface irregularities caused by the warp yarns become smaller.

There are plain weave, twill weave, and junior weave in the triangular structure of the fabric. The weave is the most smooth, but the strength of the fabric is the weakest. In the case of plain weave, there is a disadvantage that the smoothness is somewhat superior and the structure is strong against friction but the fabric thickness is thin.

Therefore, as the organization of the screen fabric 14 of the present invention, which requires durability, it is difficult to select plain weave or runner.

In the case of twill weave, the smoothness of the fabric is somewhat less than that of the plain weave or the main weave, provided we assume that the same material and the same thickness of yarn are used at weaving, .

More specifically, twill twill is a structure that forms a comb-like pattern on the surface of a fabric, and is thicker than plain weave, and is dense and compact. The characteristics of twill are smooth and soft luster, which can express color clearly, is resistant to friction and does not crease well, so it is less deformed after washing.

Accordingly, the inventor of the present invention has confirmed that it is preferable to twill the tissue constituting the screen fabric.

However, the twill fabrics constituting the screen fabric 14 are characterized by a large amount of oblique exposure. That is, as shown in FIG. 3 (a), the twill formed in the comb direction on the surface is a protruding portion of the warp p as the ridgeline 16 (also referred to as a "special line"), The arrangement of the slopes (p) of the screen cloth 14 becomes the horizontal direction. Fig. 8 shows a micrograph of the screen fabric (a) and the screen image (b) of Fig. 3 taken along the sloped ridgeline.

Therefore, as shown in Fig. 4, a golf ball 18 struck by a golf club and spinning from below to below is horizontally arranged while striking against the screen fabric 14 and rubs in a direction perpendicular to the projected slopes p, (p) in the longitudinal direction of the fabric.

In the case of a regular twill, a '2/1 right (↗)' or a '2/2 right (↗)' in which the slope (p) is up at two organization points and down at one organization point, There are many '3/1 right (↗)', '2/1 left (↖)', '2/2 left (↖)' and '3/1 left (↖)'.

Although the weft density coefficient of the screen fabric 14 is higher than or equal to the slope density coefficient in the present invention, there is an advantage in that the exposure of the warp p is less than that of the conventional screen fabric 4, And to minimize the rupture of the currently exposed slopes (p).

In the present invention, a twill organization point is formed to minimize the twill twist of the slope (p) protruding from the surface of the ridge line (16). Unlike the conventional method, the slope (p) , '1/3 rightward (↗)', '1/2 leftward', '1/3 leftward', 'downward' . As the tissue point at which the incline p is up is reduced, the incline p exposure on the screen fabric 14 with the twill weave according to the present invention is also reduced.

In addition, in the present invention, a twill structure is provided, in which the impact received by the screen fabric 14 at the time of hitting the golf ball 18 can be received more from the ridge line 16 having a supporting force, To form a structure for spreading evenly to the left and right. For this purpose, the present invention does not form a regular twill but forms an organization with an anomalous twill or an anisotropic jig.

In the present invention, it is considered as the selection of the twill weave. When the twill weave has a similar structure to the irregular twill weave, the surface smoothness is considerably improved compared to the general twill weave, The surface exposure of the inclination pursued by the present invention is minimized, and the damage of the inclination due to the impact of the golf ball can be prevented.

When the golf ball 18 hits the screen fabric 14, the spin of the golf ball 18 and the direction of travel are formed in the northeast coordinates as shown in FIG. 5 when many right handles are used as reference.

Therefore, it is advantageous for the structure in the screen fabric 14 constituting the image screen 12 to form the ridge line 16 having more shock-supporting force in the northeast direction similar to the spinning direction of the golf ball 18 and the direction of the impact point . 3 (b), in the screen fabric 14 constituting the image screen 12, in order to make the ridgeline 16 to be in the right direction (↗) when viewed on the image screen 12, As shown in Fig.

Considering the mechanical action of the golf ball being struck on the video screen as described above and considering that the striking impact force of the golf ball 18 is more uniformly dispersed evenly up and down and right and left, Or as a modified example, a tissue is formed in an anisotropic manner.

In Fig. 6, "X" is a tissue point whose slope (p) is in an up state.

In the present invention, a twill organization is formed, but the main organization may be an irregular twill, and the auxiliary organization may be a regular twill, a plain weave, and a junior.

Further, in the present invention, it is possible to form the screen fabric 14 only in an anomalous twist pattern or a regular twill pattern, or as another example, the screen fabric 14 can be formed only in an irregular run pattern, p) should have a relatively low exposure compared to weft (w).
