BACKGROUND
[0002] The present invention relates to a penetration type screen
for screen golf, and more particularly to a penetration type screen
used for so-called screen golf which uses a virtual golf simulation
apparatus that allows golfers to play golf through virtual golf
images projected onto a screen.
[0003] As the interest in golf has recently increased, a virtual
golf simulation system, which is called "screen golf" and which
provides realism allowing users to enjoy golf games indoor as
though they play golf games on actual golf courses, has been
introduced.
[0004] The virtual golf simulation system is implemented such that
the system provides, as virtual reality, the same images as those
of actual golf courses in order to provide realism allowing golfers
to enjoy golf as though they play golf games on actual golf courses
and also provides realistic moving golf ball images.
[0005] Specifically, an image provided by the golf simulation
apparatus is projected onto a screen provided at a front side of a
screen golf booth that forms a specific size of space such that a
golfer can enjoy screen golf by striking a golf ball toward the
screen while viewing the image projected onto the screen.
[0006] However, in the conventional screen golf system, golf balls
struck by the golfer are spread in a messy way over the floor of
the booth in which the screen golf system is installed,
deteriorating user satisfaction associated with golfing
environments.
[0007] Accordingly, there is a need to develop technology which
allows a golf ball to disappear from view after the golf ball is
struck such that the booth in which the screen golf system is
installed is kept tidy to provide pleasant golfing environments and
which also further improves the realism of virtual golf as the
struck golf disappears from view.

DETAILED DESCRIPTION
[0032] An embodiment of a penetration type screen for screen golf
according to the present invention will now be described in more
detail with reference to the accompanying drawings.
[0033] First, a screen golf system including a penetration type
screen according to the present invention is schematically
described as follows with reference to FIG. 1.
[0034] As shown in FIG. 1, the screen golf system is installed in a
screen golf booth 1 having a specific size of space defined by side
walls.
[0035] A penetration type screen S is attached to a front side of
the screen golf booth 1 and a projector 210 that is operated by a
golf simulator 200 is provided to project a virtual golf simulation
image including a golf course, a background, a moving image of a
golf ball, and the like onto the penetration type screen S.
[0036] If a golfer steps up to a swing plate 100 provided at the
bottom of the booth 1 and strikes a golf ball placed on a golf mat
110 with a golf club, the struck golf ball flies toward the
penetration type screen S. The golf ball penetrates through the
penetration type screen S. Movement of the struck golf ball is
detected by a sensor 220 and the golf simulator 200 implements the
detected movement of the struck golf ball as an image and projects
the image on the penetration type screen S through the projector
210.
[0037] The penetration type screen S is basically formed of a
plurality of screen elements that are arranged side by side and is
implemented such that the struck golf ball passes between screen
elements.
[0038] A buffer is provided at a rear side of the penetration type
screen S such that the penetrated golf ball is buffered and drops
to a floor of the screen golf booth 1. The golf ball which has
dropped to the floor of the screen golf booth 1 may be conveyed and
provided back to the swing plate 100 through a ball conveyor (not
shown) provided inside the screen golf booth 1.
[0039] The penetration type screen S is described below in more
detail with reference to FIGS. 2 to 7.
[0040] As shown in FIG. 2, the penetration type screen S for screen
golf according to an embodiment of the present invention is formed
of a plurality of screen elements 10 arranged side by side.
[0041] Two frames 20 are provided respectively at upper and lower
end portions of the plurality of screen elements 10 so as to
support the array of screen elements 10.
[0042] Each of the frames 20 may be provided as a single integrated
frame that supports the entirety of the plurality of screen
elements 10 and may also be provided as a plurality of sub-frames
21, 22, and 23 into which the frame 20 is divided as shown in FIG.
2.
[0043] In the case in which the frame 20 is divided into a
plurality of sub-frames (such as sub-frames 21, 22, and 23) such
that each of the sub-frames 21 supports partial screen elements
(where a combination of the sub-frame and the partial screen
elements supported by the sub-frame is referred to as a
"sub-penetration-type screen"), the penetration type screen may be
configured by arranging a plurality of sub-penetration-type screens
side by side such that, when part of the penetration type screen
has a problem or needs to be washed, it is possible to separate and
replace a sub-penetration-type screen corresponding to the part,
achieving ease of work.
[0044] On the other hand, a conventional penetration type screen is
configured by arranging a plurality of slats side by side, forming
gaps between the slats through which a golf ball can pass. The
conventional penetration type screen has a problem in that, as golf
balls repeatedly pass through the gaps between the slats, the sizes
of the gaps are gradually increased, deteriorating the external
appearance, and also has a problem in that an image is not properly
projected on the penetration type screen due to the increased sizes
of the gaps.
[0045] The penetration type screen S according to the present
invention is characterized in that the screen elements 10 are
arranged side by side such that the screen elements 10 at least
partially overlap each other and are each inclined at a specific
angle.
[0046] That is, the screen elements 10 are mounted, overlapping
each other, such that a part of one screen element 10-1 overlaps a
part of another screen element 10-2 and a part of the screen
element 10-2 overlaps a part of another screen element 10-3 as
shown in FIG. 3. Here, each screen element 10 is mounted inclined
at a specific angle.
[0047] It is preferable that the overlapping portion of each of the
screen elements 10 not exceed a half of one screen element and that
portions of the screen elements 10, each of which is smaller than a
half of one screen element, overlap each other.
[0048] FIG. 3 is a cross-sectional view of the arranged screen
elements shown in FIG. 2 taken along line I-I in FIG. 2. In FIG. 3,
illustration of the frame part is omitted.
[0049] It is preferable that, as shown in FIG. 3, the direction of
light of the projector 210 be taken into consideration when the
plurality of screen elements 10 is arranged (or installed) such
that the screen elements 10 overlap each other and are each
inclined at a specific angle.
[0050] That is, when the projector 210 projects an image obliquely
from one side as shown in FIG. 1, light of the projector 210
travels obliquely toward the penetration type screen as shown in
FIG. 3.
[0051] Here, if each of a plurality of screen elements is arranged
to be inclined such that a front surface of the screen element
faces incident light from the projector as shown in FIG. 4, shadows
D are created by light from the projector such that thick stripes
are viewed over the entirety of the penetration type screen, which
may cause simulation images not to be smoothly viewed.
[0052] Accordingly, it is possible to prevent shadows from being
created by light from the projector by arranging (or installing)
the screen elements such that light of the projector is directed
toward side surfaces of the overlapping portions of the screen
elements as shown in FIG. 3.
[0053] In addition, by arranging the screen elements such that the
screen elements overlaps each other, taking into consideration the
direction of light of the projector as shown in FIG. 3, it is
possible to significantly reduce the thicknesses of stripes viewed
on the penetration type screen and to allow the stripes to appear
uniform, thereby allowing the user not to feel visual
discomfort.
[0054] If a golf ball is struck toward the penetration type screen
in which the plurality of screen elements is arranged such that the
screen elements overlap each other and are each inclined at a
specific angle, the struck golf ball passes through the penetration
type screen while opening an overlapping portion of screen
elements. The opened screen elements immediately return to the
original state. Here, since each of the screen elements is formed
of spandex, the screen elements can elastically return to an
original state and can easily be kept in the original shape even
when a golf ball repeatedly passes through the screen elements.
[0055] Conventionally, elasticity is given to a plurality of slats,
which are arranged side by side to constitute a penetration type
screen, by manufacturing each of the slats using non-elastic cloth
and providing a number of means for providing elasticity to end
portions of the slats. However, since the slats are lacking in
elasticity, there is a problem in that it is not possible to
prevent the sizes of the gaps between slats from being easily
increased as golf balls repeatedly pass between the slats over a
long period of time and there is also a risk that the portions of
the slats, which are formed of cloth, may be separated from the
portions thereof which provide elasticity.
[0056] The penetration type screen according to the present
invention overcomes such problems by forming each of the plurality
of screen elements of spandex and improves stability (or
reliability) by performing fire retardant processing on the spandex
material to prevent the spandex material from burning.
[0057] Specifically, after fire retardant processing is performed
on spandex thread, the fire-retardant-processed spandex thread and
fire-retardant-processed silicon may be used to manufacture each
screen element or may be used to manufacture a single large screen
and then to cut the single large screen into screen elements.
[0058] On the other hand, as golf balls repeatedly pass between the
plurality of screen elements 10 which are arranged such that each
screen element overlap each other and are each inclined at a
specific angle as shown in FIG. 3, the overlapping state of each
screen element may not be maintained.
[0059] For example, as golf balls repeatedly pass between the
plurality of screen elements over a long period of time, a part of
one screen element which should overlap another screen element such
that the part of the one screen element is located behind the other
screen element may be wrongly arranged in front of the other screen
element, which may cause the screen elements to be viewed as being
partially dislocated when viewed over the entire penetration type
screen.
[0060] Accordingly, it is more preferable that a component for
performing a function to maintain the arrangement of the plurality
of screen elements in which the screen elements overlap each other
and are each inclined at a specific angle be provided. FIGS. 5 to 8
illustrate an example in which such a function is performed through
a frame that supports the arrangement of the plurality of screen
elements.
[0061] FIG. 5 illustrates an example in which a support guide
portion supports the arrangement of the plurality of screen
elements and FIG. 6 is a cross-sectional view of the sub-frames 21,
22, and 23 shown in FIG. 1 taken along line I-I in FIG. 1.
[0062] FIG. 7 is an exploded view of the sub-frames 21, 22, and 23
shown in FIG. 6 and FIG. 8 is a perspective view of the sub-frames
shown in FIG. 7.
[0063] As shown in FIGS. 5 to 8, it is preferable that support
guide portions 31 and 32 be formed on the frame 20 so as to support
the arrangement of the plurality of screen elements 10 in which the
screen elements 10 overlap each other and are each inclined at a
specific angle.
[0064] Each of the support guide portions 31 and 32 is formed in a
shape corresponding to the arrangement of the plurality of screen
elements 10, in which the screen elements 10 overlap each other and
are each inclined at a specific angle, so as to allow the
arrangement of the plurality of screen elements 10 to be
maintained.
[0065] That is, the support guide portions 31 and 32 provide
supporting force to allow the screen elements to quickly return to
the original state when a golf ball penetrates through the screen
elements.
[0066] As shown in FIG. 5, the frame 20 may include a first frame
portion 20-1 which is arranged at a front side of the plurality of
screen elements 10 and a second frame portion 20-2 which
corresponds to the first frame portion 20-1 and is arranged at a
rear side of the plurality of screen elements 10 and is coupled to
the first frame portion 20-1 to support the plurality of screen
elements 10.
[0067] That is, the frame 20 may be constructed by coupling the
first frame portion 20-1 and the second frame portion 20-2 to each
other so as to support all screen elements.
[0068] A first support guide portion 31 having a shape
corresponding to the arrangement of the plurality of screen
elements 10, in which the screen elements 10 overlap each other and
are each inclined at a specific angle, may be formed on the first
frame portion 20-1 and a second support guide portion 32 having a
shape corresponding to the arrangement of the plurality of screen
elements 10, in which the screen elements 10 overlap each other and
are each inclined at a specific angle, may be formed on the second
frame portion 20-2 and the first frame portion 20-1 and the second
frame portion 20-2 may be coupled to each other to allow the first
support guide portion 31 and the second support guide portion 32 to
support the arrangement of the plurality of screen elements 10.
[0069] FIG. 6 illustrates a state in which the frame 20 is
constructed by coupling a plurality of sub-frames 21, 22, and 23 to
each other. As shown in FIG. 7, it is preferable that the
sub-frames 21, 22, and 23 respectively include first sub-frame
portions 21-1, 22-1, and 23-1, which are arranged at a front side
of the plurality of screen elements 10, and second sub-frame
portions 21-2, 22-2, and 23-2 which correspond respectively to the
first sub-frame portions 21-1, 22-1, and 23-1 and which are
arranged at a rear side of the plurality of screen elements 10 such
that the second sub-frame portions 21-2, 22-2, and 23-2 are coupled
to the first sub-frame portions 21-1, 22-1, and 23-1 to support the
plurality of screen elements 10.
[0070] As shown in FIGS. 6 and 7, an end portion X of a first
sub-frame portion 21-1 of one sub-frame 21 and an end portion Y of
a second sub-frame portion 22-2 of another sub-frame 22 may be
arranged respectively at the front and rear sides of the screen
elements 10, facing each other, such that the end portion X of the
first sub-frame portion 21-1 and the end portion Y of the second
sub-frame portion 22-2 are coupled to each other.
[0071] In the same manner, an end portion X of a first sub-frame
portion 22-1 of the sub-frame 22 and an end portion Y of a second
sub-frame portion 23-2 of another sub-frame 23 may be arranged
respectively at the front and rear sides of the screen elements 10,
facing each other, such that the end portion X of the first
sub-frame portion 22-1 and the end portion Y of the second
sub-frame portion 23-2 are coupled to each other.
[0072] Accordingly, there are advantages in that it is possible to
configure the sub-frames such as the sub-frame 21 so as to
continuously support the screen elements 10 without discontinuous
portions between the sub-frames while enabling simple assembly of
the sub-frames.
[0073] Here, it is preferable that, as shown in FIGS. 7 and 8, a
first support guide portion 31 having a shape corresponding to the
arrangement of the plurality of screen elements, in which the
screen elements overlap each other and are each inclined at a
specific angle, be formed on the first sub-frame portions 21-1,
22-1, and 23-1 and a second support guide portion 32 having a shape
corresponding to the arrangement of the plurality of screen
elements, in which the screen elements overlap each other and are
each inclined at a specific angle, be formed on the second
sub-frame portions 21-2, 22-2, and 23-2 and the first sub-frame
portions 21-1, 22-1, and 23-1 and the second sub-frame portions
21-2, 22-2, and 23-2 may be coupled to each other to allow the
first support guide portion 31 and the second support guide portion
32 to support the arrangement of the plurality of screen
elements.
[0074] In addition, it is preferable that, as shown in FIG. 8(a),
the first support guide portion 31 include first inclined surface
portions 31a such that inclined front surfaces of the plurality of
screen elements 10 are secured to and supported by the first
inclined surface portions 31a, and first risers 31b which are
formed at end portions of the first inclined surface portions 31a
such that one side surfaces of the screen elements are secured to
and supported by the first risers 31b.
[0075] It is also preferable that, as shown in FIG. 8(b), the
second support guide portion 32 include second inclined surface
portions 32a such that inclined rear surfaces of the plurality of
screen elements 10 are secured to and supported by the second
inclined surface portions 32a, and second risers 32b which are
formed at end portions of the second inclined surface portions 32a
such that the other side surfaces of the screen elements are
secured to and supported by the second risers 32b.
[0076] Accordingly, the structure of the first support guide
portion 31 including the first inclined surface portions 31a and
the first risers 31b and the structure of the second support guide
portion 32 including the second inclined surface portions 32a and
the second risers 32b are coupled to each other to form the
structure in which the screen elements 10 overlap each other and
are each inclined at a specific angle.
[0077] FIG. 9 illustrates a state in which a plurality of support
members 40 is arranged at specific intervals at the rear sides of
the plurality of screen elements 10 such that the plurality of
support members 40 crosses the plurality of screen elements 10.
[0078] It is preferable that the support members 40 be formed of a
highly elastic substance such as spandex or rubber. Both end
portions of the support members 40 may be fixed to wall surfaces or
alternatively additional structures may be provided such that the
support members 40 are fixed to the structures.
[0079] Accordingly, the support members 40 support the plurality of
screen elements such that the screen elements can return to the
original shapes even when golf balls pass between the screen
elements.
[0080] Various embodiments of the present invention have been
described in the best mode.
[0081] The penetration type screen for screen golf according to the
present invention can be used in industries related to a so-called
Screen Golf for a user to be able to play a virtual golf round by
golf simulation based on a virtual reality.
