[Technical Field]
[0001] The present invention relates to an archery finger tab, and particularly, to an archery
finger tab that can support an archer's hand that draws a bowstring, by eliminating
physically unnatural factors while an archer draws and releases the bowstring.
[Background Art of the Invention]
[0002] In general, archery actions consecutively include setting corresponding to a ready
posture, nocking that is an action of nocking an arrow in a bowstring, hooking that
is an action of hooking archer's fingers on the bowstring, drawing for equally pushing
and drawing the bow and the string, holding that is an action immediately before shooting,
releasing that is an action of releasing the string to shoot the arrow, and follow-through
that is a final action that is naturally performed as a result of the release.
[0003] During these actions, finger tabs are used as aids that protect archer's fingers
until a bowstring is drawn and naturally released.
[0004] Finger taps have a profound effect of maintaining the balance of power of a hand
that draws the bowstring similarly to touching the bowstring against the the archer's
nose and lips in order to allow an archer to take a concentrated and consistent posture
for aiming without being disturbed in posture during the releasing process.
[0005] Individual archers have different shapes of hands that draw a bowstring with their
fingers hooked on the bowstring, hooking angles at which the bowstring is drawn are
different, and forces exerted on each hand are differently exerted on respective parts
of the hand, including the fingers.
[0006] The archers have to steadily release the bowstring during shooting. However, if the
hooking action is unstable, it is not possible to steadily release the bowstring.
This causes problems such as the vibration of the bowstring, the resulting unstable
shaking of an arrow, and the deviation of the arrow from the aimed target.
[0007] That is, the unnaturalness of an archer's hand during the hooking action makes the
posture of the archer's hand unstable, and the unstable hand posture leads to inconsistent
shooting.
[0008] In most of the finger taps currently on the market, support plates are manufactured
at right angles. Therefore, there is an inconvenience that archers should adapt the
archers' hands and hooking actions to the finger taps instead of adapting the finger
taps to their hooking positions.
[0009] The cause of this problem can be found in that the archers have different finger
lengths and thicknesses, and the spreading degree of respective fingers and the bending
degree of the fingers in a natural state vary.
[0010] Therefore, the finger tabs should be able to cope with the archers' most comfortable
hand shapes and habits.

[Summary of the Invention]
[Problems that the Invention is to Solve]
[0012] The invention has been made in order to solve the problems of the related art and
satisfy the needs thereof, and an object thereof is to provide an archery finger tab
that allows an archer to change and fix the vertical position and the supporting angle
of a part for supporting an archer's thumb in order to cope with individual archer
preferences, such as the length of thumbs, the bending degree of the thumbs, and the
supporting area of the thumbs, so as to match individual archers' most natural hand
shapes and habits.
[Means for Solving the Problems]
[0013] In order to achieve the above object, a characteristic configuration of the archery
finger tab according to the invention includes a body part that has a plate shape
one surface of which faces a palm and has a first guide rail, having a length in upward-downward
direction or forward-rearward direction, formed at a rear upper part thereof; a mount
that has a plate shape, is fixed or unfixed by a first fastening part in correspondence
with the first guide rail, and is provided with a first hinge part disposed in the
forward-rearward direction at an upper or lower part; and a support plate that has
a plate shape, is provided with a second hinge part at one side, and is fixed or unfixed
with the second fastening part in a state where the first hinge part and the second
hinge part are disposed in a straight line. The support plate is pivotable about the
first fastening part and is pivotable on the other side about the first and second
hinge parts.
[0014] In addition, the mount may be formed with a second guide rail having a length in
the forward-rearward direction or the upward-downward direction intersecting the first
guide rail, the fixing by the first fastening portion may be performed by pressing
the body part and the mount at an intersection position between the first guide rail
and the second guide rail against each other so as to in close contact with each other,
and the fixing by the second fastening part may be performed by pressing an end part
of the first hinge part and an end part of the second hinge part facing the second
hinge part against each other so as to be in close contact with each other.
[0015] Also, the first fastening part may include a bolt and a nut that press the body part
and the mount by screwing with the body part and the mount interposed therebetween,
and a first elastic member may be further provided to apply a frictional force depending
on the degree of screwing between the bolt and the nut to a pressed part facing the
mount.
[0016] In addition, the second fastening part may include a bolt and a nut for pressing
the first and second hinge parts by screwing with the first hinge part and the second
hinge part interposed therebetween, and a second elastic member may be provided to
apply a frictional force depending on the degree of screwing between the bolt and
the nut to a pressed part facing the second hinge part.
[Advantages of the Invention]
[0017] According to the configuration of the invention described above, there is an effect
of providing a stable release of the bowstring by adjusting the forward-rearward position,
height, and inclination of the support plate in response to the thumb length and habit
of each archer to allow the archer's thumb to be supported, thereby eliminating the
unnaturalness of the archer's thumb to prevent resulting distraction of the archer'
mind.

[Detailed Description for Carrying Out the Invention]
[0019] In describing the invention, the expression "upper side" or "upper part" will be
described as referring to a direction opposite to the direction of gravidity with
respect to the center of each component of the invention or a component part that
is present in the opposite direction, and the expression "lower side" or "lower part"
will be described as referring to a direction opposite to the direction indicated
by the expression "upper side" or "upper part" or a part that is present in the opposite
direction.
[0020] In addition, in describing the invention, the expression "front side" or "front part"
will be described as referring to a direction in which an archer views on the basis
of a general posture in which the archer performs a release, or a component part that
is present in the direction, and the expression "rear side" or "rear part" will be
described as referring to a direction opposite to the direction indicated by the expression
"front side" or "front part" or a part that is present in the opposite direction.
Since a leftward-rightward direction can be differently expressed depending on the
right-handed and left-handed, the leftward-rightward direction will be expressed as
both sides, one of both the sides will be expressed as one side, and the other side
will be expressed as the other side.
[0021] Hereinafter, preferred embodiments of the invention will be described with reference
to the accompanying drawings.
[0022] As illustrated in Figs. 1a and 1b, an archery finger tab 10a, 10b according to an
embodiment of the invention has a plate-shaped body part 12a, 12b one surface of which
faces the palm of the archer, and a tab member 14 is installed on the front side of
the body part 12a, 12b so as to nock a bowstring instead of archers' fingers.
[0023] Here, the finger tabs 10, 10b illustrated in Figs. 1a and 1b can be distinguished
from each other depending on formation of a first guide rail 16a, 16b having a length
in upward-downward direction at a rear upper part of the body part 12a, 12b, formation
of a first guide rail 16a, 16b having a length in a forward-rearward direction, and
an installation relationship of a mount 18, 18', 18" corresponding to each first guide
rail 16a, 16b.
[0024] The first guide rail 16a, 16b is located at the rear upper part of the body part
12a, 12b of which the formation region substantially corresponds to an archer's thumb,
as can be seen in Figs. 1a and 1b.
[0025] Here, although the first guide rail 16a, 16b illustrated in Fig. 1a or 1b is expressed
as a hole shape that has a length in the upward-downward direction or the forward-rearward
direction and passes through the body part 12a, 12b toward both sides, the first guide
rail 16a, 16b is not limited to this and may have a shape extending to a hatched part
of Fig. 1a or 1b.
[0026] In addition, the first guide rail is formed not only as the hole shape but also,
as referred to in (b) of Fig. 2, may be formed in a groove (F) of a sectional shape
that increases in width in a depth direction toward one side (side 1) of the body
part 12a, 12b from the other side (side 2) thereof. In this case, the first guide
rail may be allowed to be slidingly moved or fixed by fitting a head part of a bolt
20a' of a first fastening part 20' for fixing or unfixing the mount (18, 18', 18")
into the above-described groove F and fastening a nut 20b' to the bolt, on the other
side.
[0027] Meanwhile, as illustrated in Figs. 1A and 1B, the mount 18, 18', 18" facing the first
guide rail 16a, 16b has a plate shape that faces the first guide rail 16a, 16b and
the surface of the body part 12a, 12b at a peripheral edge thereof, and has a second
guide rail 19, 19', 19" formed at a position corresponding to the first guide rail
16a, 16b.
[0028] In addition, the mount 18, 18', 18" has a first hinge part 22, which is disposed
in the forward-rearward direction, formed at an upper or lower edge.
[0029] The first hinge part 22 may be formed in a sleeve shape having a hollow cavity in
the forward-rearward direction.
[0030] The mount 18, 18', 18" formed in this way is installed in the body part 12a, 12b
by locating the second guide rail 19, 19', 19" in correspondence with the above-described
first guide rail 16a, 16b and by fixing the mount and the body part at an intersection
position between the first and second guide rails with the first fastening part 20,
20'.
[0031] The first fastening part 20 is fixed or unfixed in such a manner that the nut 20b
is located to prevent the rotation of the first fastening part with respect to the
first guide rail 16a, 16b on one side of the body parts 12a, 12b, and the body part
12a, 12b and the mount 18, 18', 18" placed between the bolt and the nut are pressed
depending on the degree of fastening of the bolt (20a) to the nut from the other side.
[0032] Here, a first elastic member 24 for applying a frictional force depending on the
degree of the pressing may be installed at a position where the pressing is performed
while facing the mount 18, 18', 18", and various types of rubber or disk springs may
be used as the first elastic member 24.
[0033] The first elastic member 24 applies a frictional force such that the mount 18, 18',
18" is movable and rotatable with respect to the body part 12a, 12b due to a physical
force in a state where the first elastic member is partially elastically deformed
in response to a fastening force resulting from the first fastening part 20, 20',
and thereby, allows the archer to adjust the position of the mount 18, 18', 18" that
fits his/her own thumb.
[0034] When the mount 18, 18', 18" is located from the above process, the first elastic
member 24 applies a frictional force for suppressing the movement and rotation of
the mount 18, 18', 18" with respect to the body part 12a, 12b as the fastening force
of the first fastening part 20, 20' is increased.
[0035] A support plate 26 provided with a second hinge part 28 formed in a sleeve shape
similarly to the first hinge part 22 formed in a plate shape on one side is installed
in the first hinge part 22 of the above-described mount 18, 18', 18".
[0036] Such a support plate 26 is installed in a such manner that the first and second hinge
parts 22 and 28 are fixed and unfixed by fastening a second fastening part 30 passing
through hollow cavities thereof in a state where the first hinge part 22 and the second
hinge part 28 are disposed in a straight line, and thereby is pivotable about the
second fastening part 30.
[0037] Additionally, the second fastening part 30 may include a bolt 30a passing through
the hollow cavities with the first hinge part 22 and the second hinge part 28 interposed
therebetween, and a nut 30b screwed to the bolt 30a.
[0038] In addition, a second elastic member 32, which applies a frictional force to a pressed
part facing the second hinge part 28 due to the pressing by the second fastening part
30 depending on the degree of the pressing, may be further installed in the configuration
of the second fastening part 30.
[0039] Similarly to the first elastic member 24 mentioned above, the second elastic member
32 functions to adjust the pivoting angle of the support plate 26 temporarily before
being fixed by the second fastening part 30.
[0040] As described above, the support plate 26 is a part where the archer's thumb is put,
is pivotable from a fixed position by the first fastening part 20, 20', and is pivotable
from a fixed position of the second fastening part 30.
[0041] In addition, the support plate 26 is slidingly movable in the upward-downward direction
and the leftward-rightward direction in a longitudinal direction of the first guide
rail 16a, 16b and in a longitudinal direction of the second guide rail 19', 19" before
being fixed by the first fastening part 20, 20'.
[0042] Therefore, the support plate 26 can support archer's thumbs in response to archers
having different thumb lengths, having different thumb bending degrees, and having
different personal preferences.
