Definitions

  • This invention relates to a guard baton or police billy or the like, and in particular to a crosshandled guard baton.
  • crosshandled guard baton means a guard baton which has a short handle branchedly secured on a main club body at midway between an end and the central portion of the club length.
  • a conventional guard baton of this type is described in US Patent 4132409.
  • the guard baton comprises a club having a crosshandle rigidly secured thereto and extending perpendicularly therefrom.
  • An outer part of the handle defines a gripping surface which is stationary with respect to the club.
  • a sleeve is rotatably mounted on the handle between the club and the gripping surface.
  • the handle is axially divided into a stationary portion and a rotatable portion, the former being gripped by several fingers of the user's hand to brake rotating or swinging motions of the club.
  • the guard baton may be used to enlarge the scale of hand actions. But in certain cases, the length of the main club body of the guard baton is not enough to reach an enemy.
  • the crosshandle of the guard baton is of circular section.
  • the present invention overcomes the above-mentioned drawbacks with an improved crosshandled guard baton which comprises a club, a crosshandle branched on the club at a biased place towards a first club end and having a branching length comparable to a man 's hand palm, and a mounting base between the club and the crosshandle.
  • the crosshandle has a stationary portion and a rotatable portion with respect to the club.
  • this invention makes improvement relative to longtitudinal extensibility of the guard baton as will be apparent later.
  • a crosshandled guard baton comprising a club, and crosshandle branched on the club at a biased place towards a first club end and having a branching length comparable to a man's hand palm, and a mounting base between the club and the crosshandle, the crosshandle being provided with a rotatable portion and a stationary portion with respect to the club.
  • the club has a hollow cylindrical form, inside of which at least one cylindrical form, inside of which at least one cylindrical slender member is accomodated in a retracted form to be extended telescopically out of a second end through a club end opening.
  • the crosshandle is provided, lengthwise from the mounting base outward, with a rotatable portion, a stationary portion and a further rotatable portion, and is elliptical in cross-section, whereby motions of the club including extension of the telescopic slender member are controlled conveniently by tightening and loosening of handgrip around the crosshandle.
  • a crosshandled guard baton comprising a club, and crosshandle branched on the club at a biased place towards a first club end and having a branching length comparable to a man's hand palm, and a mounting base between the club and the crosshandle, the crosshandle being provided with a rotatable portion and a stationary portion with repsect to the club.
  • the club has a hollow cylindrical form, inside of which at least one cylindrical slender member is accomodated in a retracted form to be extended telescopically out of a second end through a club end opening.
  • the crosshandle is provided, lengthwise from the mounting base outward, with the stationary portion and the rotatable portion, and is elliptical in cross-section, whereby motions of the club including extension of the telescopic slender member are controlled conveniently by tightening and loosening of handgrip around the crosshandle.
  • This invention is generally summarized as featuring a crosshandled guard baton which comprises a club having a longitudinal 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 a breadthal 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 a 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.
  • a longitudinal shaft typically 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 with the lower and upper grip members 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 ones in independence of the motion with the club and central grip.
  • the handle is modified to dispense with the rotatable lower grip from the rest of the members defining the handle.
  • 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.
  • Fig. 1 is a perspective view of an embodiment of the present invention.
  • Fig. 2 is a front view of the embodiment shown in Fig. 1 with a break to show internal structures.
  • Figs. 3 to 10 are front views of several embodiments with breaks to show respectively various internal structures.
  • Fig. 11 is a perspective view of another embodiment of the present invention featuring in addition of a strap band as is seen.
  • Figs. 12 to 18 are front views of different embodiments with sections or partial sections (or breaks) to show respectively various internal structures.
  • 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.
  • the club length is divided at the place of a base 2 for mounting the handle A into two portions of 1a for long or shank portion and 1b for short or hilt portion.
  • Said handle A has a length comparable to a breadthal length of a man's hand palm and is typically defined by three portional members of a lower grip 5, central grip 4, and upper grip 6 which are laid on one another with inter-slidability to form an upright stand on the mounting base 2 formed on the club 1, and internally of the handle, a longitudinal shaft 3, typically 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, and 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 in independence of a rotary motion of the club and central grip.
  • the grip members 5, 6 are sometimes noted “rotatable grip members" in the following.
  • the numerals 9, 10 are sleeves inserted between the shaft 3 and inside the grip members 5, 6.
  • 8 is a plug which seals an end opening of the club at the hilt portion.
  • 16 is a grip cover which is attached on the hilt portion. 1aa, drawn in virtual lines, is an extended portion of the club as will be apparent in later.
  • the handle A is meant by a “biased place toward a club end", however, it is recommended to determine it so that the hilt portion 1b may have a length comparable to the longitudinal length of the handle A.
  • the handle A may act as a cross guard of a sword.
  • the numeral 34 is a strap band for hitching a user's hand to secure the gripping.
  • any hard material is suitable; wood, plastic, light metal or iron. Of them, wood or reinforced plastic is most suited.
  • Interior of the club 1 in this instance is one through space, not divided, and in making use of the interior space, accommodated are a plurality of slender cylinderical members 11, 12 in retracted form which are extensible telescopically to form the portion like the one 1aa shown in Fig.
  • the member 11 having a larger diameter than the other member 12 is shaped to be thick at its end placed to be close to the plug 8 and to be thin at its end placed to be a slightly out of an open end of the club 1 to form a subtle taper forward as a whole, and a base end of the member 11 is abutted at a buffer member 7 located inside the plug 8, and therein an inner or core member 12 is so inserted as for the outer periphery of its forward end to be fitted tightly with the end of the enclosing outer-member 11, and a forward opening end of the member 12 being plugged with a cap 14, and the base end of the inner member 12 is reinforced by a plug 15.
  • Fig. 2, 13 is a weight which is comprised of metallic beads or particles, which will accelerate the centrifugal force.
  • new features are mainly in that the core cylinder 12 has partly a space wherein a weight 13 composed of particles is received.
  • the weight 13 is, instead of beads, a solid metal which is packed in interior of the core cylinder 12, and other features may be regarded as being much the same as in the preceeding example.
  • the core member 13 is made of a kind of metal, that is, the member 13 itself is a weight.
  • cylindrical members in the preceding example are simplified to be one metal-made member 18 having a partial interior space in which a weight 13 is received.
  • 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 a weight 13 is received.
  • the cylindrical member 11 is shortened to be comparable to a length of the shank portion 1a and the interior of the club 1 is divided to two spaces wherein the hilt space 19 is left as a cavity, which may be used to store personal properties.
  • the arrangement for extensible members is much the same as in Fig. 8, and in the space 19 accommodated is a lightening device, wherein 20 is a battery, 21 is a lamp, 22 is a manual on-off switch.
  • the arrangement for the lightening device in Fig. 9 is replaced to 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.
  • the handle A is secured to the club 1 by screw engagement of a king pin 3a which extends across the club 1 to thread into a tapped bore 29 located at the bottom of the shaft 3, and a hook 33 is added around the base of the handle A to hook the strap band 34.
  • the handle A is structured with two grip members, main grip 4 and upper grip 6 with one rotatable member 6.
  • 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 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 thread engagement as shown.
  • the spring 37 may be replaced to be a coiled spring having a length comparable to the core member and may be set at the same position to urge the core member so as to reinforce a let-off action thereof.
  • the inner space of the core member 12 is divided by two partitions, one of which is employed to receive a weight 13 and the other 12a is used to receive a spring 37.
  • 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 strongly.
  • the inner space of the core member 12 is divided by two partitions, one of which is employed to receive a solid metal weight 50, in place of metal particles in the preceeding example.
  • 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 to tapping engagement 41 for the pin 30 and a member 42 is 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 making the grip 6 rotatable.
  • a gas ejecting device is incorporated in an upper portion of the handle A.
  • 45 is a recess to accommodate a gas bomb 46, which is inset therein, 47 is a nozzle for ejection, 48 is a pivotal lever to act as a trigger, and 49 is a hole to let off the gas.
  • the inventive guard baton is retractile and thereby so saving in the point of space or length needed to be carried by a user, and in case of need, this can extend to form a kind of pseudo-sword, hence so convenient to the police or guard personnel.
