This invention relates to a guard baton or police
billy or the like. Particularly, this relates to a
crosshandled guard baton.
The term "crosshandled guard baton" is intended to
indicate a guard baton which has a short handle branchedly
secured on a main club body at a biased place or location
between an end and a central portion of the club length.
A guard baton of this type is described in U.S. Patent
10 4,132,409 which has been only the sole conventional art
according to the inventor's knowledge.
In this U.S. patent, the handle is axially ~ivided
into two portions, stationary and rotatable, and the
description therein teaches that the stationary one is put
into act when rotating or swinging of the club is intended.
However, in view of the fact that it is not determinable
whether the crosshandle is gripped by the right hand or the
leEt hand of a baton user, and also probable is a change of
gripping this handle from the right hand to left or vice
versa. Thus, a device for braking the rotating club should
be improved to be more convenient to grip by either hand.
This was the starting point of this invention and, in
addition thereto, new devices are introduced to the present
inventive baton as the description herein will make them

apparent in the following.
On the other hand, KARATE, a kind of sports or
practice for combat without a hand weapon, has become
popular in the world and such a combat practice is
sometimes used by an assailant against the police or
security personnel and therefore, those who are entitled to
wear such a guard property as a baton are desirous that
their guard property be improved, in particular, be
improved so as to provide KARATE actions on an enlarged
scale and to which purpose a rotatable crosshandled baton
i5 basically appropriate. An improvement in the braking
devi~e for a guard baton is also particularly suited,
because in KARATE techniques wielding of two hands is
important, but at the same time, a quick stop cf a hand
action is necessary to make use of a foot to kick or to add
an attack by footwork.
The present invention is generally summarized as
featuring a crosshandled guard baton which comprises a club
having a longitudi.nal axis and a crosshandle transversely
branched on the club at a biased place toward a club end,
wherein the crosshandle (the term "crosshandle" will often
be abbreviated to "handle" in the following) has a
branching length comparable to the width length of a man's
hand palm and is typically defined by three portional
members of a lower grip, central grip and upper grip which
are laid on one another to form an upright stand on a
1 3 1 53 1 0
-- 3
mounting base formed on the club, and the handle is
preferred to have an elliptic shape in section, of which
major axis is conformed to the club axis.
Turning to internal structures of the handle, a
longitudinal shaft, typically comprising a connection of a
few segments, is secured on the mounting base and is
extended to reach through an outer end of the upper grip,
and the shaft is rotatably supported on the lower and upper
grip memhers while the central grip is fastened to the
shaft such that the club is turnable around the handle with
a concurrent motion of the central grip, hence keeping the
lower and upper grips o~ the motion with the club and
central grip. Further, the handle may be modified to
dispense with the rotatable lower grip from the other
members defining the handle.
Further, the present invention is particularly
directed to the guard batons in equipment of at least one
telescopically extensible pipe or cylindrical member which
is usually accommodated in a hollow space provided in the
club body.

DESCRIPTION 9F THE EMBODIMENTS
With rPference to Figs. 1, 2, 11, and 12, the
numeral 1 is a club having a longitudinal axis. A is a
crosshandle having an axis which is substantially upright
to the club axis or transversely branched on the club 1 at
a biased place toward a club end. For convenience, the
club length is divided at the place of a base 2 for
mounting the handle A into two portions of la for a long or
shank portion and lb for a short or hilt portion. And said
handle A has a length comparable to the width of a man's
hand palm and is typically defined by three portional
-r~
1 31 53 1 0

members of a lower grip 5, central grip 4, and upp~r grip
6 which are laid or stacked on one another with inter-
slidability to form an upright stand on the mounting base
2 formed on the club l internally of the handle, a
longitudinal shaft 3, typically a connection of a few
segments, is secured on the base 2 and is extended to reach
through an outer end of the upper grip 6. The shaft 3 is
rotatably supported with the lower and upper grips 5, 6
while the central grip 4 is fastened to the shaft 3 such
that the club 1 is turnable around the handle A with a
concurrent motion of the central grip 4, hence keeping the
lower and upper ones 5, 6 independent of a rotary motion of
the club and central grip. In t:his connection, the grip
members 5, 6 are sometimes noted "rotatable grip members"
in the following.
Reference is added to general explanation of these
drawings, the numerals 9, 10 are sleeves inserted between
the shaft 3 and inside the grip members 5, 6. A plug 8
which seals an end opening of the club at the hilt portion.
A grip cover 16 which is attached on the hilt portion. An
extended portion, shown in broken lines, of the club 7aa
will be apparent later.
In the above, where to place the handle A is meant
by "a biased place toward a club end", however, it is
recommended to determine the biased place so that the hilt
portion lb may have a length comparable to the longitudinal
length of the handle A.

In use of a guard baton as a pseudo-sword with the
hilt portion gripped, the handle A may act as a cross guard
of a sword.
In Fig. 11, the numeral 34 is a strap band for
hitching a user's hand to secure the gripping.
As for material to manufacture the inventive guard
batons, any hard material is available; wood, plastic,
light metal or iron. Of them, wood or reinforced plastic
is most suited.
Turning to explanations of the drawings as a whole,
reference to devices accommodated in the club 1 in Fig. 2
is made as follows:
Interior of the club 1 in this instance i5 one
through space, not divided, and in making use of the
interior space, accommodated are a plurality of slender
cylindrical members 11, 12 in retracted form which are
extensible telescopically to form a portion such as the
portion laa shown in Fig. l, the member 11 having a larger
diameter than the other member 12 and being tapered so as
to be thick at its end adjacent to the plug 8 and to be
thin at its other end extending slightly out of an open end
of the club 1. A base end of the member 11 is abutted to
a buffer member 7 located inside the plug 8, and an inner
or core member 12 is so inserted that the outar periphery
of its forward end is fitted tightly with the end of the
enclosing outer-member 11. A forward opening end of the
member 12 is plugged with a cap 14, and a base end of the
1 3 1 53 1 0
-- 7
inner member 12 is reinforced by a plug 15.
These retracted members 25, 27 will be extended by
the action o~ centrifugal force when the club is gripped at
the club hilt 16 by a user and swung, for instance, wherein
the tight fits of the membex 11 to the member 12 and also
of the member 11 to the inside face of the club 1, with aid
of the tapering as noted, is helpful to form a kind of
reduced coupling, hence to avoid an unexpected easy
extension or slip-out due to a small force; adequate tight
fittings are necessary.
In Figs. 2, 13 is a weight which is comprised of
metallic beads or particles, which will accelerate the
centrifugal force.
In the following, new embodiments will be
described, but therein, without repeating the same,
descriptions will be mainly directed to other new features
than those which were already noted in connection with the
preceding drawings.
As shown in Fig. 3, the core cylinder 12 has a
space in which a weight 13 composed of particles is
received.
As shown in Fig. 4, the weight 13, instead of
comprising beads, is of solid metal which is packed in
interior of the core cylinder 13; other features may be
regarded as being much the same as in the preceding
example.

With reference to Fig. 5, the core member 13 is
itself of metal, that is, the member 13 itself is a weight.
With reference to Fig. 6, the cylindrical members
in the praceding example are simplified to be one metal-
made member 18 having a partial interior space in which aweight 13 is received.
With reference to Fig. 7, one cylindrical member 12
employed is one having a length comparable to the whole
length of the club 1 and having a through space, in which
~ weight 13 is received.

With reference to Fig. 8, the cylindrical member 11
is shortened to be comparable to a length of the shank
portion la and the interior of the club 1 is divided into
two spaces wherein the hilt space 19 is left as a cavity,
which may be used to store personal properties.
With reference to Fig. 9, the arrangement for
extensible members is much the same as in Fig. 8, and in
the space 19 accommodated is a lighting or illuminating
device, wherein 20 is a battery, 21 is a lamp, 22 is a
manual on-off switch.
With reference to Fig. 10, the arrangement for the
lighting device in Fig. 9 is replaced by a gas ejecting
device, wherein 23 is a gas bomb, 24 is an opening of a
pipe for gas ejection, 25 is a ram, 26 is a ram head, 27 is
a trigger button, and 28 is a spring to urge the trigger
rod.
With reference to Fig. 12, the handle A is secured
to the club 1 by screw engagement of a king pin 3a which
extends across the club 1 to th~read into a tapped bore 29
located at the bottom of the shaft 3j and a hook 33 is
added around the base of the handle A to hook a strap band
34.
With reference to Fig. 13, the handle A is
structured with two grip members, main grip 4 and upper
grip 6 with one rotatable member 6.
With reference to Fig. 14, the cylindrical members
11~ 12 are much the same as in Fig. 13, and a new part 36,
named a reinforcing member, is introduced which is located
in alignment to the king pin 30. The member 36 has a
through bore for the pin 30 and also a spring 37 as shown
1 31 531 0
g
to press the inside of the core cylinder 12 by urging
action of the spring so that a let-off of the core cylinder
12 may be controlled, and the spring 37 may be set to be
removable by mounting it by means of a threaded engagement
as shown.
With reference to Fig. 15, the inner space of the
core member 12 is divided into two partitions, one of which
is employed to receive a weight 13 and the other 12a is
used to receive a spring 37. In applying the spring 37 in
a few examples shown in the preceding drawings, inner face
of the partition 12a, that is, tip portion of the member 12
is preferable to be contrived to curve open or close so as
for the spring 37 to be clamped more stronglyO
With reference to Fig. 16, in a similar way, the
inner space of the core member 12 is divided into two
partitions, one of which is employed to receive a solid
metal weight 50, in place of metal particles in the
preceding example.
With reference to Fig. :L7, the mounting base 2 is
transformed to be a concave upward in section to receive
the bottom of the main grip 4 and one rotatable grip 6 is
incorporated in the handle A, wherein a member 40 is inset
in the bottom face of the main grip 4 for tapping
engagement 41 with the pin 30. A member 42 i5 also inset
in the top face of the main grip 4 to receive a shaft 44
with thread engagement, around which bearings 6a, 6a are
mounted for ..........
1 31 53 1 0
makins the grip 6 rotatable.
With reference to the Fig. 18, a gas ejecting device is iDcorporated
in an upper portion of the handle A. Speci~ically, 45 is a recess
to accom~odate a gas boob 46, ~hich is inset therein, 47 is a
noz~le for eiection, 48 is a pi~otal 10~er to act as a trig~er, and
49 is a hole to let off the gas.
As is understood fro~ the descriPtions so far, the inventi~e guard
baton is retractile and thereby SQ sa~ing in the point of spaoe or
length needed to be carri0d by a user, and in case of need, this
can extend to for~ a kind of pseudo-sNord, hence so convenient to
the police or guard personnel.
