Description

PENETRATION TYPE SCREEN FOR SCREEN GOLF AND SCREEN GOLF SYSTEM HAVING THE SAME

The present invention relates to a penetration type screen for screen golf and a screen golf system having the same, and more particularly, to a penetration type screen used in a golf simulation, also known as screen golf to allow a golf simulation user to enjoy golf via an imaginary golf image projected on the screen and a screen golf system having the same.

Recent increasing interest in golf causes the advent of a golf simulation system called “screen golf” that provides a virtual reality simulation of golfing at a golf course even in a room.

To provide such a realistic virtual reality simulation of golfing at a golf course, a golf simulation system provides, for example, an image of an actual golf course and an image of a golf ball in flight based upon the way in which the golf simulation user has actually hit a golf ball.

More specifically, in the golf simulation system, a golf simulation device is provided to project an image on a screen provided at a front wall surface portion of a screen golf booth defining a predetermined volume of space. In this case, the golf simulation user is able to enjoy screen golf by hitting a golf ball toward the screen while seeing a golf course image projected on the screen.

When enjoying golf using the above described screen golf system, however, golf balls are randomly dispersed on the bottom of the booth after colliding with the screen and this deteriorates golfing experience.

Accordingly, there is a demand for a screen golf system which enables a golf ball, hit by the golf simulation user, to be hidden from the sight to keep the booth provided in the screen golf system clean, thereby achieving pleasant golfing experience and also, which presents automated supply of golf balls, thereby achieving enhanced convenience.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a penetration type screen for screen golf in which a golf ball, hit by a user, penetrates the screen so as to be hidden from the sight, resulting in more pleasant golfing experience and also, in which the golf ball, having passed through the screen, is automatically transferred to a swing plate, resulting in greater convenience, and a screen golf system having the same.

In accordance with one aspect of the present invention, the above and other objects can be accomplished by the provision of a penetration type screen for screen golf including a plurality of screen component members arranged in parallel along a first frame provided at one side of a front wall surface portion of a screen golf system and a second frame provided at the other side of the screen golf system, and elastic supporting members each fixed to one end of each screen component member and the first frame, or to the other end of the screen component member and the second frame, the elastic supporting members being made of elastic fibers or rubber to elastically support the screen component members.

Hereinafter, embodiments of a penetration type screen for screen golf and a screen golf system according to the present invention will be described in detail with reference to the accompanying drawings.

First, the screen golf system according to the present invention will be schematically described with reference to FIG. 1.

As illustrated in FIG. 1, the screen golf system includes a screen golf booth B having a predetermined volume of space defined by a front wall surface portion and a sidewall SW.

A screen S is installed to define the front wall surface portion of the screen golf booth B, and an image display device P is provided to project, for example, an image of a golf ball in flight, an image of an actual golf course and a background image onto the screen S. The image display device P is operated by a golf simulator C.

If a user hits a golf ball with a golf club at a swing plate SP, the hit golf ball will fly toward the screen S. In the present invention, the golf ball is able to penetrate the screen S. A sensor is provided to sense motion of the hit golf ball, such that the golf simulator C converts the sensed motion into a predetermined image and the image display device P projects the image onto the screen S.

The screen S is a penetration type screen in which a plurality of screen component members are basically arranged in parallel such that the hit golf ball passes between the screen component members.

The penetration type screen will be described hereinafter in more detail with reference to FIGS. 2 to 20.

The penetration type screen according to the present invention is installed to frames provided at the front wall surface portion of the booth B provided in the screen golf system. The frames include a first frame provided at one side of the front wall surface portion of the booth B and a second frame provided at the other side of the front wall surface portion of the booth B.

In addition, the penetration type screen according to the present invention includes the plurality of screen component members arranged in parallel along the first frame and the second frame, and elastic supporting members fixed respectively to one end of each screen component member and the first frame or to the other end of the screen component member and the second frame, the elastic supporting members being made of elastic fibers or rubber and adapted to elastically support the respective screen component member in a tightly strained state.

The screen component members may be formed into vertically split members, i.e. vertical component members 21 as illustrated in FIGS. 2(A), 5(A), 6(A), 6(B), 7(A) and 8(A), or may be formed into horizontally split members, i.e. horizontal component members 22 as illustrated in FIGS. 2(B), 5(B), 7(B) and 8(B).

These

screen component members

21 and 22 have to be kept tightly strained to prevent gaps therebetween or uneven surfaces thereof. This is possible as the elastic supporting members elastically support the

screen component members

21 and 22.

Preferably, the elastic supporting members elastically support both ends of each screen component member in a state wherein the screen component member is strained tightly by a tensile force.

Preferably, the

screen component members

21 and 22 have a width suitable to allow a golf ball to smoothly pass between the neighboring screen component members.

Each of the elastic supporting members has one end fixed to one of the frames and the other end fixed to a corresponding one of the screen component members, and is made of a material having high elasticity, such as e.g., elastic fibers including spandex and rubber.

The elastic supporting member includes a first fixing portion adapted to be fixed to the first frame or the second frame, a second fixing portion adapted to be fixed to one end of the screen component member, and an elastic body, both ends of which define the first fixing portion and the second fixing portion.

In embodiments as illustrated in FIGS. 2 and 5 to 8, the above described elastic supporting members are formed into any one of general supporting members, both side supporting members, center supporting members, eccentric supporting members, center reinforcement supporting members and eccentric reinforcement supporting members.

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

First, two embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIG. 2.

FIG. 2(A) illustrates the embodiment in which the vertical component members 21 are provided, and FIG. 2(B) illustrates the embodiment in which the horizontal component members 22 are provided.

As illustrated in FIG. 2(A), a plurality of vertical component members 21 is arranged in parallel in a horizontal direction along the first frame 10a and the second frame 10b provided respectively at the top and bottom thereof.

The first frame 10a and the second frame 10b are fixed to the front wall surface portion of the booth B provided in the screen golf system, respectively, by use of first fixtures 11a and second fixtures 11b.

The first frame 10a and the second frame 10b may be formed of, for example, braided steel wires or steel rods, but are not limited in terms of constituent materials and shapes so long as they can rigidly support the screen component members.

The

fixtures

11a and 11b preferably function not only to fix both ends of the first frame 10a or the second frame 10b, but also to keep the first frame 10a or the second frame 10b tight with a high tensile force.

In addition, to prevent the first frame 10a or the second frame 10b from drooping by a weight thereof, supports (not shown) may be additionally installed at certain several positions of the

frames

10a and 10b.

In FIG. 2(A), the elastic supporting members provided at upper and lower ends of each vertical component member 21 are general supporting members 31.

In the embodiment illustrated in FIG. 2(A), each of the general supporting members 31 includes a first fixing portion 31a fixed to the first frame 10a or the second frame 10b, a second fixing portion 31b fixed to the upper end or the lower end of the vertical component member 21, and a general supporting body 31c.

The first fixing portion 31a and the second fixing portion 31b of the general supporting member 31 have substantially the same width and also, have substantially the same width as a width of the vertical component member 21.

The general supporting body 31c is made of elastic fibers including spandex, rubber, or the like.

The vertical component members 21 are densely arranged without gaps, and the general supporting members 31 elastically support the vertical component members 21 to tightly strain the vertical component members 21.

The first fixing portion 31a may be configured to fix the general supporting body 31c and the

frame

10a or 10b to each other by means of a separate fastener, or may be directly fixed to the

frame

10a or 10b to surround the

frame

10a or 10b as illustrated in FIG. 4.

The second fixing portion 31b, which serves to fix the general supporting body 31c to the end of the vertical component member 21, for example, may be directly sutured to the vertical component member 21 by sewing, or may be fixed to the vertical component member 21 by means of a separate fastener.

Next, the embodiment illustrated in FIG. 2(B) will be described. As illustrated, a plurality of horizontal component members 22 is arranged in parallel in a vertical direction along the first frame 10a and the second frame 10b provided respectively at opposite lateral sides thereof.

The first frame 10a and the second frame 10b are fixed to the front wall surface portion of the booth B provided in the screen golf system, respectively, by use of the first fixtures 11a and the second fixtures 11b.

The

fixtures

In FIG. 2(B), the elastic supporting members provided at opposite lateral ends of each horizontal component member 22 are the general supporting members 31.

The general supporting members 31 have substantially the same configuration and operational effects as those of the embodiment illustrated in FIG. 2(A) except for an installation direction thereof and thus, a detailed description thereof will be omitted for brevity.

FIG. 3 illustrates a part of the penetration type screen illustrated in FIG. 2(A) in an enlarged scale, and simply illustrates a penetration course of a golf ball.

As illustrated in FIG. 3(A), if it is assumed that a golf ball 1 flies such that a center point of the golf ball 1 is present in a range R between an imaginary longitudinal center axis A1 of any one vertical component member 21a and an imaginary longitudinal center axis A2 of an adjacent vertical component member 21b, the golf ball 1 will pass between the two

vertical component members

21a and 21b.

After the golf ball 1 passes, as illustrated in FIG. 3(B), the

vertical component members

21a and 21b are restored to an original state thereof by elasticity of the elastic supporting members, i.e. the general supporting members 31. In this case, elasticity of the

vertical component members

21a and 21b also contribute to the restoration.

If the center point of the golf ball 1 deviates from the range R, the golf ball 1 will pass between one of the two vertical component members and a next vertical component member.

Although FIG. 3 illustrates the embodiment of FIG. 2(A), it is equally applicable to the penetration type screen including the horizontal component members illustrated in FIG. 2(B).

FIGS. 4(A) and 4(B) illustrate a penetration course of a golf ball through the penetration type screens according to the respective embodiments of FIGS. 2(A) and 2(B) in side sectional views.

As illustrated in FIGS. 4(A) and 4(B), preferably, the

frames

10a and 10b, the vertical component members 21 or the horizontal component members 22, and the elastic supporting members 31 are installed to the front wall surface portion F of the booth B provided in the screen golf system, and a chamber 40 having a predetermined volume is defined behind the penetration type screen S.

Preferably, a damping means 50 to dampen the golf ball 1 having passed through the penetration type screen S is provided in the chamber 40.

The damping means 50 may be, for example, a damping member, such as a net or sponge, spaced apart rearward from the penetration type screen S by a predetermined distance.

A predetermined structure or device is placed on a bottom surface 41 of the chamber 40, and serves to transfer the fallen golf ball that has been dampened by the damping means 50. This will be described hereinafter.

Accordingly, the hit golf ball 1 acts to open and pass between the vertical component members 21 as illustrated in FIG. 4(A) or between the horizontal component members 22 as illustrated in FIG. 4(B), and after passage of the golf ball 1, the vertical component members 21 or the horizontal component members 22 are restored to an original state thereof.

Hereinafter, additional two embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIG. 5.

FIG. 5(A) illustrates the embodiment in which the vertical component members 21 are provided, and FIG. 5(B) illustrates the embodiment in which the horizontal component members 22 are provided.

First, in the embodiment illustrated in FIG. 5(A), the plurality of vertical component members 21 is arranged in parallel along the first frame 10a and the second frame 10b arranged at the top and bottom thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are both side supporting members 32 to elastically support the vertical component members 21.

The configuration of the embodiment of FIG. 5(A) is substantially equal to that of the embodiment of FIG. 2(A) except for the both side supporting members 32, and thus, a detailed description of the remaining configuration will be omitted, and the following description focuses on the both side supporting members 32 as the feature of the present embodiment.

The both side supporting members 32 are fixed to opposite side edges of either end of the vertical component member 21 to elastically support the vertical component member 21.

More specifically, as illustrated in FIG. 5(A), with respect to the upper end of each vertical component member 21, a pair of both side supporting members 32 has one end fixed to the frame 10a and the other end fixed to positions spaced apart in opposite directions, by a predetermined distance, from an imaginary longitudinal center axis of the vertical component member 21, thereby serving to elastically support the vertical component member 21.

The above described both side supporting members 32 are adapted to tightly support opposite side edges of each vertical component member 21, thus being capable of not only elastically supporting the vertical component members 21 without a gap, but also supporting a partial area of each vertical component member 21 rather than supporting the entire end region of the vertical component member 21. This is preferable to assure more smooth passage of a golf ball between the vertical component members 21.

In addition, the elasticity of the both side supporting members 32 has a direct effect on the boundary of the neighboring vertical component members 21, and this allows the vertical component members 21 to be easily returned to original positions thereof after passage of a golf ball.

Next, in the embodiment illustrated in FIG. 5(B), the plurality of horizontal component members 22 is arranged in parallel in a vertical direction along the first frame 10a and the second frame 10b arranged respectively at opposite lateral sides thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective horizontal component members 22, are the both side supporting members 32 to elastically support the horizontal component members 22.

The both side supporting members 32 illustrated in FIG. 5(B) have substantially the same configuration and operation effects as those illustrated in FIG. 5(A) except for an installation direction thereof, and thus, a detailed description thereof is substituted by the above description of FIG. 5(A).

Hereinafter, additional two embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIG. 6. FIGS. 6(A) and 6(B) illustrate the embodiments in which the penetration type screen includes the vertical component members 21.

First, in the embodiment illustrated in FIG. 6(A), the plurality of vertical component members 21 is arranged in parallel along the first frame 10a and the second frame 10b arranged at the top and bottom thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are center supporting members 33 to elastically support the vertical component members 21.

The configuration of the embodiment of FIG. 6(A) is substantially equal to that of the embodiment of FIG. 2(A) except for the center supporting members 33, and thus, a detailed description of the remaining configuration will be omitted, and the following description focuses on the center supporting members 33 as the feature of the present embodiment.

Each of the center supporting members 33, as illustrated in FIG. 6(A), includes a first fixing portion 33a fixed to the

frame

10a or 10b, a second fixing portion 33b fixed to the end of the vertical component member 21, and a center supporting body 33c.

The first fixing portion 33a and the second fixing portion 33b have substantially the same width, and the second fixing portion 33b is fixed at a position within a predetermined range on the basis of an imaginary longitudinal center axis of the vertical component member 21.

More specifically, the center supporting member 33 elastically supports only a predetermined region on the basis of the center of the vertical component member 21, and the remaining lateral end regions of the vertical component member 21 are not supported by the center supporting member 33.

In a state wherein the vertical component member 21 is tightly strained and elastically supported by the center supporting member 33 as described above, the elasticity of the center supporting member 33 has an effect on the lateral end regions of the vertical component member 21 to some extent, and thus, it is possible to prevent the neighboring vertical component members 21 from being normally spaced apart from each other.

In addition, the elasticity of the center supporting members 30 has a slight effect on the boundary of the neighboring vertical component members 21, assuring more easy passage of a golf ball between the vertical component members 21. Since the elasticity of the center supporting members 33 still exerts elastic restoration of the vertical component members 21 and owing to elasticity of the vertical component members 21, the vertical component members 21 can be easily restored to an original state thereof after passage of the golf ball.

Next, in the embodiment illustrated in FIG. 6(B), the plurality of vertical component members 21 is arranged in parallel along the first frame 10a and the second frame 10b arranged at the top and bottom thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are eccentric supporting members 34 to elastically support the vertical component members 21.

The configuration of the embodiment of FIG. 6(B) is substantially equal to that of the embodiment of FIG. 2(A) except for the eccentric supporting members 34, and thus, a detailed description of the remaining configuration will be omitted, and the following description focuses on the eccentric supporting members 34 as the feature of the present embodiment.

Each of the eccentric supporting members 34, as illustrated in FIG. 6(B), includes a first fixing portion 34a fixed to the

frame

10a or 10b, a second fixing portion 34b fixed to the end of the vertical component member 21, and an eccentric supporting body 34c.

The first fixing portion 34a and the second fixing portion 34b have substantially the same width, and the second fixing portion 34b is fixed at an eccentric position on the basis of an imaginary longitudinal center axis of the vertical component member 21.

More specifically, with respect to the upper end of the vertical component member 21, an eccentric supporting member 34-1 elastically supports only a predetermined lateral edge region (i.e. the left edge region of the drawing) and the remaining region of the upper end of the vertical component member 21 is not supported by the eccentric supporting member 34-1.

In addition, with respect to the lower end of the vertical component member 21, an eccentric supporting member 34-2 elastically supports only a predetermined lateral edge region (i.e. the right edge region of the drawing). In this case, preferably, the eccentric supporting member 34-1 provided at the upper end of the vertical component member 21 and the eccentric supporting member 34-2 provided at the lower end of the vertical component member 21 are positioned on a diagonal line.

With diagonal arrangement of both the eccentric supporting members 34-1 and 34-2 at the upper and lower ends of the vertical component member 21, it is possible to balance the elastic force of both the eccentric supporting members 34-1 and 34-2.

The eccentric supporting member 34 preferably has a width equal to or smaller than half a width of the vertical component member 21.

When the vertical component members 21 are tightly strained and elastically supported by the eccentric supporting members 34 as described above, it is possible to apply balanced elasticity to the vertical component members 21 and to assure more smooth passage of a golf ball between the vertical component members 21. In addition, since the elasticity of the eccentric supporting members 34 has a direct effect on the boundary of the vertical component members 21, thus allowing the vertical component members 21 to be easily returned to original positions thereof after passage of the golf ball.

Hereinafter, additional two embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIG. 7. FIG. 7(A) illustrates the embodiment in which the vertical component members 21 are provided, and FIG. 7(B) illustrates the embodiment in which the horizontal component members 22 are provided.

First, in the embodiment illustrated in FIG. 7(A), the plurality of vertical component members 21 is arranged in parallel along the first frame 10a and the second frame 10b arranged at the top and bottom thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are center reinforcement supporting members 35 to elastically support the vertical component members 21.

The configuration of the embodiment of FIG. 7(A) is substantially equal to that of the embodiment of FIG. 2(A) except for the center reinforcement supporting members 35, and thus, a detailed description of the remaining configuration will be omitted, and the following description focuses on the center reinforcement supporting members 35 as the feature of the present embodiment.

Each of the center reinforcement supporting members 35, as illustrated in FIG. 7(A), includes a first fixing portion 35a fixed to the

frame

10a or 10b, a second fixing portion 35b fixed to the end of the vertical component member 21, and a center reinforcement supporting body 35c.

The first fixing portion 35a has a width corresponding to a width of a predetermined region on the basis of an imaginary longitudinal center axis of the vertical component member 21. The second fixing portion 35b has a width substantially equal to a width of the vertical component member 21. The center reinforcement supporting body 35c is tapered from the second fixing portion 35b to the first fixing portion 35a.

The center reinforcement supporting member 35 provides the entire vertical component member 21 with elasticity. In particular, the center reinforcement supporting member 35 provides the center region of the vertical component member 21 with strong elasticity and simultaneously, provides opposite side regions (not connected to the frame) of the vertical component member 21 with appropriate elasticity. This is preferable to allow a golf ball to easily pass between the vertical component members 21 and also, to allow the vertical component members 21 to be easily returned to original positions thereof after passage of the golf ball.

Next, in the embodiment illustrated in FIG. 7(B), the plurality of horizontal component members 22 is arranged in parallel in a vertical direction along the first frame 10a and the second frame 10b arranged respectively at opposite lateral sides thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective horizontal component members 22, are the center reinforcement supporting members 35 to elastically support the horizontal component members 22.

The center reinforcement supporting members 35 illustrated in FIG. 7(B) have substantially the same configuration and operation effects as those illustrated in FIG. 7(A), and thus, a detailed description thereof will be omitted for brevity.

Hereinafter, additional two embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIG. 8. FIG. 8(A) illustrates the embodiment in which the vertical component members 21 are provided, and FIG. 8(B) illustrates the embodiment in which the horizontal component members 22 are provided.

First, in the embodiment illustrated in FIG. 8(A), the plurality of vertical component members 21 is arranged in parallel along the first frame 10a and the second frame 10b arranged at the top and bottom thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are eccentric reinforcement supporting members 36 to elastically support the vertical component members 21.

The configuration of the embodiment of FIG. 8(A) is substantially equal to that of the embodiment of FIG. 2(A) except for the eccentric reinforcement supporting members 36, and thus, a detailed description of the remaining configuration will be omitted, and the following description focuses on the eccentric reinforcement supporting members 36 as the feature of the present embodiment.

Each of the eccentric reinforcement supporting members 36, as illustrated in FIG. 8(A), includes a first fixing portion 36a fixed to the

frame

10a or 10b, a second fixing portion 36b fixed to the end of the vertical component member 21, and an eccentric reinforcement supporting body 36c.

The first fixing portion 36a has a width corresponding to a predetermined eccentric region on the basis of an imaginary longitudinal center axis of the vertical component member, and the second fixing portion 36b has substantially the same width as a width of the vertical component member 21. The eccentric reinforcement supporting body 36c is tapered from the second fixing portion 36b to the first fixing portion 36a.

Preferably, an eccentric reinforcement supporting member 36-1 fixed to the upper end of the vertical component member 21 and an eccentric reinforcement supporting member 36-2 fixed to the lower end of the vertical component member 21 are positioned on a diagonal line.

With diagonal arrangement of both the eccentric reinforcement supporting members 36-1 and 36-2 at the upper and lower ends of the vertical component member 21, it is possible to balance the elastic force of both the eccentric supporting members 36-1 and 36-2.

As the eccentric reinforcement supporting members 36 apply elastic supporting force to diagonal positions of the vertical component member 21, i.e. one lateral edge of the upper end and the other lateral edge of the lower end of the vertical component member 21, it is possible to apply balanced elasticity to the entire vertical component member 21. In particular, as the eccentric reinforcement supporting members 36 apply strong elastic force in a diagonal direction of the vertical component member 21 and simultaneously, apply appropriate elastic force even to the remaining region of the vertical component member 21 that is not connected to the frame and is less effected by elasticity, it is possible to allow a golf ball to easily pass between the vertical component members 21 and also, to allow the vertical component members 21 to be easily returned to original positions thereof after passage of the golf ball.

Next, in the embodiment illustrated in FIG. 8(B), the plurality of horizontal component members 22 is arranged in parallel in a vertical direction along the first frame 10a and the second frame 10b arranged at opposite lateral sides thereof, and the elastic supporting members, fixed respectively to the

frame

10a or 10b and the end of the respective vertical component members 21, are the eccentric reinforcement supporting members 36 to elastically support the horizontal component members 22.

Similar to the eccentric reinforcement supporting members 36-1 and 36-2 illustrated in the embodiment of FIG. 8(A), the eccentric reinforcement supporting member 36-1 or 36-2 illustrated in the embodiment of FIG. 8(B) includes the first fixing portion 36a, the second fixing portion 36b and the eccentric reinforcement supporting body 36c.

However, differently from the embodiment of FIG. 8(A), the embodiment of FIG. 8(B) has a feature in that the eccentric reinforcement supporting members 36-1 and 36-2 provided at opposite lateral ends of the horizontal component member 22 are arranged in a line rather than being diagonally arranged.

As illustrated in FIG. 8(B), the first fixing portion 36a is located at an upper edge of one lateral end of the horizontal component member 22, and the eccentric reinforcement supporting body 36c is tapered from the second fixing portion 36b to the first fixing portion 36a.

Preferably, the eccentric reinforcement supporting member 36-1 provided at one lateral end of the horizontal component member 22 and the eccentric reinforcement supporting member 36-2 provided at the other lateral end of the horizontal component member 22 are horizontally symmetrical to each other.

As to the horizontal component member 22, it is preferable that a pair of eccentric reinforcement supporting members 36 is horizontally symmetrical to each other as illustrated in FIG. 14 rather being diagonally arranged because the horizontal component member 22 is affected by gravity differently from the vertical component member 21.

FIGS. 9 to 11 illustrate other embodiments of the present invention.

In the embodiment illustrated in FIGS. 9 to 11, at least one supporting line 60 is provided at rear surfaces of the plurality of

screen component members

21 or 22 arranged in parallel along the first frame 10a and the second frame 10b. The supporting line 60 is arranged substantially parallel to the first and

second frames

10a and 10b, and serves to prevent deformation of the

screen component members

21 or 22.

Although FIGS. 9 and 10 illustrate the embodiment in which the supporting line 60 is applied to the penetration type screen according to the embodiment of FIG. 5(A), the supporting line 60 is equally applicable to all the embodiments of the present invention.

As illustrated in FIG. 9, preferably, a plurality of supporting lines 60 are arranged at a predetermined interval at the rear surfaces of the plurality of screen component members 21 of the penetration type screen S to extend substantially parallel to the first and

second frames

10a and 10b, thus serving to prevent deformation of the screen component members 21 upon passage of a golf ball.

Although installation of one or more supporting lines 60 are possible, an excessively great number of supporting lines 60 may make passage of a golf ball difficult and therefore, it is preferable to install an appropriate number of supporting lines 60.

In the embodiment illustrated in FIG. 9, a third frame 10c and a fourth frame 10d are arranged respectively at opposite lateral sides of the penetration type screen S to extend substantially perpendicular to the first and

second frames

10a and 10b. One end of each supporting line 60 is fixed to the third frame 10c and the other end of the supporting line 60 is fixed to the fourth frame 10d.

To this end, each supporting line 60 includes a first fastener 61a to fix one end of the supporting line 60 to the third frame 10c and a second fastener 61b to fix the other end of the supporting line 60 to the fourth frame 10d.

Next, in the embodiment illustrated in FIG. 10, one end of the supporting line 60 is fixed to a first one 21a of the plurality of screen component members 21 and the other end of the supporting line 60 is fixed to a last one 21b of the plurality of screen component members 21.

To this end, the supporting line 60 includes a fastener 62a to fix one end of the supporting line 60 to the first screen component member 21a and a fastener 62b to fix the other end of the supporting line 60 to the last screen component member 21b.

The supporting line 60 may take the form of, for example, a wire made of metal, plastic or the like.

FIGS. 11(A) and 11(B) illustrate different embodiments of the supporting line 60 when viewed from one side thereof.

First, in the embodiment illustrated in FIG. 11(A), the supporting line 60 may be simply placed at a rear surface of the penetration type screen S while being fixed to the third and

fourth frames

10c and 10d as illustrated in FIG. 9, or while being fixed to the first and last

screen component members

21a and 21b as illustrated in FIG. 10.

Next, in the embodiment illustrated in FIG. 11(B), the supporting line 60 may be supported by supporting bands 26 while being fixed to the third and

fourth frames

screen component members

21a and 21b as illustrated in FIG. 10.

The supporting bands 26 take the form of loops provided at the rear surface of each screen component member 21 and the loops have an inner diameter suitable for insertion of the supporting line 60. These supporting bands 26 may be provided at the rear surfaces of all or some of the screen component members 21 of the penetration type screen S.

The supporting bands 26 may be attached or sewed to the rear surfaces of the screen component members 21, or may be integrally formed with the screen component members 21.

FIGS. 12 and 13 illustrate other embodiments of the penetration type screen for screen golf according to the present invention.

In the embodiment illustrated in FIG. 12, the penetration type screen includes a center bar 27 longitudinally provided at the center of a front surface of the screen component member 21.

Specifically, FIG. 12(A) illustrates the front surface of the screen component member 21 provided with the center bar 27 in an enlarged scale, and FIGS. 12(B) and 12(C) are respectively a side view and a plan view.

The center bar 27 protrudes forward by a predetermined distance from the center of the front surface of the screen component member 21. If the hit golf ball flies toward the screen component member 21 and collides with the center bar 27, the golf ball slips on the center bar 27 to thereby be guided to pass between the screen component members 21. Accordingly, it is possible to prevent the golf ball from bouncing from the front surface of the screen component member 21.

The center bar 27 is equally applicable to all the embodiments of the present invention.

As illustrated in FIGS. 12(A) to 12(C), the center bar 27 is positioned at the center of the screen component member 21 and may be attached to or be integrally formed with the screen component member 21.

The center bar 27 may be made of a transparent material, or may be integrally formed of the same material as the screen component member 21.

The center bar 27 may cause refraction of light when an image is projected on the penetration type screen, thus causing partial distortion of the image. Therefore, the center bar 27 preferably has a very small diameter having substantially no effect on the entire image.

Next, in the embodiment illustrated in FIG. 13, embossments 28 may be formed at the front surface of the screen component member 21. FIG. 13(A) illustrates the embossments 28 formed at the front surface of the screen component member 21 in an enlarged scale, and FIGS. 13(B) and 13(C) are respectively a side view and a plan view.

When the hit golf ball collides with the convexly raised embossments 28, the golf ball slips on the embossments 28 to thereby be guided to pass between the screen component members 21 rather than bouncing from the front surface of the screen component member 21.

As illustrated in FIGS. 13(A) to 13(C), the embossments 28 may be formed at the entire front surface of the screen component member 21, or may be concentrated on any partial region of the front surface. The embossments 28 may be integrally formed with the screen component member 21 by a certain processing method.

Preferably, since the embossments 28 formed at the front surface of the screen component member 21 may cause refraction of light when an image is projected on the penetration type screen thus causing partial distortion of the image, the embossments 28 may have an appropriate size having substantially no effect on the entire image.

Hereinafter, the penetration type screen for screen golf according to another embodiment of the present invention will be described with reference to FIG. 14.

In the embodiment illustrated in FIG. 14, the penetration type screen is divided into a plurality of divided screens S1 and S2, and the divided screens S1 and S2 respectively include a plurality of screen component members 21-1 or 21-2 arranged in parallel.

Although two or more divided screens may be provided, FIG. 14 illustrates the embodiment in which a first divided screen S1 and a second divided screen S2 constitute the penetration type screen.

The first divided screen S1 includes a plurality of first screen component members 21-1 arranged in parallel, and first elastic supporting members 33-1 connected to both ends of each first screen component member 21-1, the respective first elastic supporting members 33-1 being fixed to a first divided frame 10a-1 or a second divided frame 10b-1.

Specifically, a single divided screen is configured in such a way that the first elastic supporting members 33-1, provided at both ends of each of the plurality of first screen component members 21-1 arranged in parallel, are fixed to the first divided frame 10a-1 and the second divided frame 10b-1 to elastically support the respective first screen component members 21-1.

When the penetration type screen according to the present embodiment includes a plurality of the above described divided screens, even if anyone of divided screens malfunction or must be exchanged, it is unnecessary to exchange the entire penetration type screen and only the problematic divided screen may be exchanged, resulting in easy installation or repair.

Furthermore, as illustrated in FIG. 14, screen component members of one divided screen may have a width different from a width of screen component members of the other divided screen.

If it is assumed that a specific region of the entire penetration type screen where golf balls frequency collide is present, screen component members of any divided screen occupying the specific region may have a relatively small width to assure more easy passage of the golf balls while preventing the golf balls from bouncing from the screen component members.

In FIG. 14, the plurality of second screen component members 21-2 constituting the second divided screen S2 has a smaller width than a width of the plurality of first screen component members 21-1 of the first divided screen S1.

The second divided screen S2 is configured in such a way that the plurality of second screen component members 21-2 is arranged in parallel along a first divided frame 10a-2 and a second divided frame 10b-2, and second elastic supporting members 33-2 provided at each of the second screen component members 21-2 are fixed to the first divided frame 10a-2 and the second divided frame 10b-2 to support the plurality of second screen component members 21-2.

The first elastic supporting members 33-1 and the second elastic supporting members 33-2 are selected from all the above described elastic supporting members according to the embodiments of the present invention. Although FIG. 14 illustrates the embodiment in which the first and second screen component members 21-1 and 21-2 are vertical component members, they are not limited thereto, and the first and second screen component members 21-1 and 21-2 may be horizontal component members.

Hereinafter, other embodiments of the penetration type screen for screen golf according to the present invention will be described with reference to FIGS. 15 and 16.

First, in the embodiment illustrated in FIG. 15, a rear penetration screen RS1 is spaced apart rearward, by a predetermined distance, from the penetration type screen according to the embodiment of FIG. 14. The rear penetration screen RS1 has a plurality of penetration slits ST1, such that the golf ball 1 having passed through the penetration type screen sequentially passes through the penetration slits ST1 of the rear penetration screen RS1.

The double golf ball penetration configuration may further improve damping effects upon passage of a golf ball.

In addition, this has the effect of reducing elasticity of a golf ball to some extent when the golf ball bounces from the screen component member of the penetration type screen.

The rear penetration screen RS1 may be formed with the plurality of penetration slits ST1 by cutting, or may include a plurality of rear screen component members 29-1 arranged in parallel to define the penetration slits ST1 therebewteen.

The penetration slits ST1 may be vertically cut, or may be vertically defined between the rear screen component members 29-1 extending in a vertical direction.

The rear penetration screen RS1, as illustrated in FIG. 16, may have an upper end fixed by a fixing member RH, and a free lower end.

When the rear penetration screen RS1 is excessively tight, it may make passage of a golf ball difficult. However, providing the rear penetration screen RS1 with the free lower end may assure positive passage of a golf ball.

Although not shown in the drawings, at least one of the upper and lower ends of the rear transmission screen RS1 is provided with an elastic member (not shown) to elastically support the rear penetration screen RS1.

Although FIG. 15 illustrates the embodiment in which the rear penetration screen RS1 is installed behind the penetration type screen of FIG. 14, it is not limited thereto, and the rear penetration screen may be mounted behind the penetration type screens according to the embodiments of the present invention.

FIG. 17 illustrates a penetration type screen according to a further embodiment of the present invention, in which a rear penetration screen RS2 has horizontal penetration slits ST2.

The horizontal penetration slits ST2 of the rear penetration screen RS2 may be formed by cutting, or may be formed as horizontal rear screen component members 29-2 are arranged in parallel.

The rear penetration screen RS2 may be fixed to and elastically supported by the third frame 10c and the fourth frame 10d provided respectively at opposite lateral sides thereof. As illustrated in FIG. 17, when the rear penetration screen RS2 includes the plurality of rear screen component members 29-2, elastic members 39 are connected to the respective rear screen component members 29-2 to elastically support the rear screen component members 29-2.

Although FIG. 17 illustrates the embodiment in which both ends of each rear screen component member 29-2 of the rear penetration screen RS2 are elastically supported by the respective elastic members 39, it is not limited thereto, and only any one of both the ends of the rear screen component member 29-2 may be elastically supported by the elastic member 39.

Hereinafter, various embodiments of the screen golf system including the penetration type screen for screen golf will be described with reference to FIGS. 18 to 20.

In FIGS. 18 to 20, the penetration type screen is omitted to illustrate a more detailed configuration of the screen golf system, and configurations of a chamber behind the penetration type screen (not shown) and a golf ball transfer device are illustrated in more detail.

The screen golf system illustrated in FIGS. 18 to 20 may be provided with any one of the penetration type screens according to the above described embodiments of FIGS. 2 to 17.

The screen golf system according to the present invention, as illustrated in FIGS. 18 to 20, has a feature in that a golf ball, hit at the swing plate SP, is returned to the swing plate SP by a transfer device after passing through the penetration type screen (not shown).

First, the screen golf system according to one embodiment of the present invention will be described with reference to FIG. 18. In the screen golf system according to the embodiment of FIG. 18, the

frames

10a, 10b, 10c and 10d are fixed to the front wall surface portion F of the booth B by means of the

fixtures

11a, 11b, 11c and 11d.

The frames, to which the penetration type screen is mounted, may include only the first frame 10a and the second frame 10b, or only the third frame 10c and the fourth frame 10d, or may include the first to fourth frames 10a to 10d according to the different embodiments of the penetration type screen, and thus, the

fixtures

11a, 11b, 11c and 11d may be selectively installed.

The chamber 40 having a predetermined volume is defined inside the front wall surface portion F, and a damping means (not shown) may be provided near an inner wall surface of the chamber 40.

The screen golf system according to the present embodiment basically includes a ball supply device 70, and, as a ball transfer mechanism, a ball moving device, a discharge hole 48 and a transfer device 80.

As illustrated in FIG. 18, the discharge hole 48 is located near one end of the bottom of the chamber 40, and the ball moving device takes the form of a slope 42 inclined downward by a predetermined angle from the other end of the bottom of the chamber 40 to the discharge hole 48.

If the hit golf ball 1 having passed through the penetration type screen (not shown) is dampened by the damping means (not shown) and falls onto the slope 42 provided at the bottom of the chamber 40, the golf ball 1 moves to the discharge hole 48 along the slope 42.

The golf ball discharged through the discharge hole 48 is transferred to the ball supply device 70 by the transfer device 80.

The transfer device 80 may have various configurations, and in the present embodiment, includes a regulator 81 to provide a drive force required to move the golf ball, and a transfer passage member 82 to connect the ball regulator 81 and the ball supply device 70 to each other.

The ball supply device 70 may have various configurations so long as it can automatically supply a golf ball to the swing plate. Although FIG. 18 illustrates the embodiment using an auto tee-up device, the present invention is not essentially limited thereto, and a generally frequently used caddie machine (including a container receiving golf balls and an arm device to pick up a golf ball one by one and put the golf ball on the swing plate) may be employed.

Next, another embodiment of the screen golf system according to the present invention will be described with reference to FIG. 19.

The embodiment of FIG. 19 is basically equal to the embodiment of FIG. 18 except for a ball moving device and thus, a description of the same configurations as the embodiment of FIG. 18 will be omitted and the following description focuses on the ball moving device.

As illustrated in FIG. 19, the ball moving device of the screen golf system according to the present embodiment has a feature in that a first slope 43 and a second slope 44 are provided at opposite sides of the discharge hole 48 located approximately at the center of the bottom of the chamber 40.

The first slope 43 is inclined downward from one end of the bottom to the discharge hole 48, and the second slope 44 is inclined downward from the other end of the bottom to the discharge hole 48.

Accordingly, the hit golf ball 1 having passed through the penetration type screen (not shown) falls onto the first slope 43 or the second slope 44 and moves to the discharge hole 48 and then, after being discharged through the discharge hole 48, is transferred to the ball supply device 70 by the transfer device 80.

Then, a further embodiment of the screen golf system according to the present invention will be described with reference to FIG. 20.

The embodiment of FIG. 20 is basically equal to the embodiment of FIG. 18 except for a ball moving device and thus, a description of the same configurations as the embodiment of FIG. 18 will be omitted and the following description focuses on the ball moving device.

In the screen golf system according to the present embodiment, as illustrated in FIG. 20, the ball moving device is a conveyor device 45 installed at the bottom of the chamber 40. The conveyor device 45 serves to transfer the golf ball 1 to the discharge hole 48 provided at one side of the bottom of the chamber 40.

Accordingly, the hit golf ball 1 having passed through the penetration type screen (not shown) falls onto the conveyor device 45 and is transferred to the discharge hole 48 by the conveyor device 45 and then, after being discharged through the discharge hole 48, is transferred to the ball supply device 70 by the transfer device 80.

Preferably, the transfer device 80 illustrated in FIGS. 18 to 20 is buried in the bottom of the booth B so as to be hidden from the sight, or is covered with decorations to provide pleasant golfing experience.

Various embodiments have been described in the best mode for carrying out the invention.

A enetration type screen for screen golf and a screen golf system having the same according to the present invention are industrially applicable to, for example, a so-called screen golf system, so that a golfer can enjoy virtual golf games. Therefore, interest of the golfer is attracted toward golf and more convenience is provided to the golfer.
