Description

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 , , 1 3 1 5~ 1 0 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 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.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 is a perspective view of an embodiment of the present invention.
Figure 2 is a front view of the embodiment shown in Fig~ 1 with a break to show internal structures.

Figures 3 to 10 are front views of several embodiments with breaks to show respectively variant internal structures.
Figure 11 is a perspective view of another embodiment of the present invention featuring in addition of a strap band as is seen.
Figures 12 to 18 are front views of different embodiments with sections or partial sections (or breaks) to show respectively variant internal structures.
These drawings are prPsented to illustrate the invention and therefore these should not be construed as limiting the invention. And in the drawings, a like numeral indicates a like part, and a length of the club is sometimes shortened out of scale without a cut mark and such should not be construed to destroy the invention.

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~

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 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.

.

1 3 1 53 1 o -7A ~
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.

B
.

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 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 ..........

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.
