Description

This invention relates to a guard baton or police billy or the like, and in particular to a crosshandled guard baton.
The term "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.
According to this US patent, 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. Thus, 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.
In use, the crosshandle is gripped with the thumb and first and second fingers positioned around the stationary portion and with the third and fourth fingers around the rotatable sleeve. This guard baton is not adapted to a great number of users who may have very weak gripping force with the third and fourth fingers for rotating motions of the club.
Further, the crosshandle of this guard baton is of circular section. Thus the directional control of the club, especially when stopping the rotating motion, is not easy.
The present invention overcomes the above-mentioned drawbacks with an improved crosshandled guard baton which comprises a club, a crosshandle and possibly a mounting base between the club and the crosshandle. As like the conventional guard baton, the crosshandle has a stationary portion and a rotatable portion with respect to the club.
According to a preferred embodiment of the invention, as described in claim 1, the crosshandle is elliptic in section the major axis of which is conformed to the axis of the club. Further, the stationary portion of the crosshandle is formed by a central grip member fastened to a shaft extending axially and internally of the crosshandle, the shaft being fixed on the club and on the mounting base. The rotatable portion of the crosshandle is formed by a lower grip member and an upper grip member rotatably mounted around the shaft and respectively adjacent to the lower end and the upper end of the central grip member, the lower or upper grip member being removable from the rest of the crosshandle.
In other words, this crosshandled guard baton comprises a club having a longitudinal axis and a crosshandle transversely branched on the club at a place toward a club end, wherein the crosshandle has a branching length comparable to a breadthal length of a man's hand and is defined by three portional members of a lower grip, central grip and upper grip which are laid on one another to form a stand on a mounting base on the club, and internally of the crosshandle a longitudinal shaft is secured on the mounting base and is extended to reach through a top end of the upper grip, and the shaft is rotatably supported with the lower and upper grips while the central grip is fastened to the shaft such that the club is turnable around the crosshandle with a concurrent motion of the central grip, keeping the lower and upper ones in independence of the motion of the club and central grip. Further, the crosshandle comprises devices for removing the lower or upper grip from rest of the members defining the crosshandle.
According to another preferred embodiment of the invention, as described in claim 2, the crosshandle comprises two portional members consisting of a main grip and an upper grip which are laid on each other to form a stand on the main grip integrally extending on the club. A shaft is secured on the top of the main grip and is extended internally of the crosshandle to reach through the top end of the upper grip. The shaft is rotatably supported with the upper grip such that the club is turnable around the crosshandle with a concurrent motion of the main grip, keeping the upper grip in independence of the motion with the club and main grip. Further, the crosshandle comprises a device for removing the upper grip from the rest of the crosshandle.
In other words, the stationary portion of the crosshandle is formed by a main grip member the lower end of which is secured on the club. The rotatable portion of the crosshandle is formed by an upper grip member rotatably mounted around a shaft which is fastened to the top of the main grip member the upper grip member being removable from the main grip member.

These drawings are presented to illustrate the invention and therefore these should not be construed as limiting the invention. In the drawings a like numeral indicates a like part, and a length of the club is somewhat shortened out of scale without a cut mark and such should not be construed to destroy the invention.
It is to be noted here that the term "crosshandle" will often be abbreviated to "handle" in descriptions later.
With reference to Figs. 1 to 3, 1 is a club which is made of a hard material, for instance, wood, metal or plastic and, in the case of a plastic, it is recommended to reinforce it with tough aramid fibers, for instance, Kevlar (brandname), by interlacing such fibers in plastic layers with orientation to an longitudinal axis of the club 1. Size of a club 1 is preferably about 60 cm in length and about 3 cm in diameter. Further, it is preferable for convenience to carrying as well as adjusting a length in use that a full length of a club is divided to a plurality of short members, which will be connected, for instance, by screw fittings instantly and in place.
A handle 2 is transversely branched at a place toward an end of the club 1, a mounting base or saddle base 3 being formed to offer a flat face at the place as mentioned, on which laid first is a lower grip member 4 which is shaped to be a round brick, the contact plane of the lower grip 4 to the base 3 being formed to make a slide contact plane 5, of which function will appear later. Then, a central grip member 6 is laid on the grip member 4 to form a similar slide contact plane 11 inbetween and thereafter an upper grip member 8a is laid on the central one 6 likewise to form a slide contact plane 12 inbetween, thereto another upper grip or cap 8b is fitted over on top, but between members 8a and 8b no slide plane is made. These members after assembly as shown in the drawings will be applied to a handgrip as a handle, size of which is therefore preferably about 11 cm long and diameter of the cap member 8b is about 3.5 cm, wherein assembled grip members as a whole are preferably shaped to take a form, like a bowling pin, easy to handgrip as shown in the drawings, in other words, round side faces of the lower grip 4 and upper grip 8a are squeezed to recurve and a similar side of the central grip is made like a barrel flank, wherein an outside shape of the handle may be varied from round in section, for instance, to be elliptic in section for further ease to handgrip as shown in Fig. 2.
Making reference to internal structures, a shaft 13a, 13b (two segments are connected in alignment, but often represented by 13) is provided longitudinally of the handle 2 and is at its footing end secured on a screw 14 which is mounted transversely of the club axis, as Fig. 3 shows. The footing end may be constructed integrally with the base 3 and is extended vertically to reach top end of the grip 8a with some interconnection midway as shown in Fig. 3 wherein the shaft 13 is rotatably supported with ball bearings 16, 16, 16, 16, mounted at two vertical ends of two grip members, lower and upper, while the shaft 13 is fastened with the central grip 6, (see Fig. 2. It shows the shaft 13 in square section at X - X line in Fig. 1). The structure as noted is annotated here to explain functions in the invention. That is, "rotatably supported" means that, when a rotatably supported grip is firmly held externally, the grip member held externally remains stationary while internally the shaft 13 is let move or turn, and as will be apparent later, in use, two grips of the lower and upper are recommended to be held by the hand palm while the center grip is let free to turn with the club. and, when the turning club is intended to stop, a touch onto the central grip is used to effect braking action. Therefore, several lateral grooves 7 are provided on the central grip to enhance friction against the hand palm.
The cap 8b is mounted on the upper grip 8a with a screw fastener 9 and, when disassembling is intended, undoing the fastener 9 leads to easy finish of disassembly.
In the following descriptions to explain new embodiments, explanations will concentrate to new devices and functions which have not yet been described, with abbreviation for repeated description.
With reference to Fig. 4, the embodiment is simplified by removing the rotatably supported lower grip member from structure as shown in Fig. 1. Therefore, the shaft 13 is secured on a level comparable to top end of the central grip 6 in Fig. 1 and only the upper grip 8a, with the cap 8b is supported rotatably. Therefore, firm gripping on the upper grip is recommended to rotate and additional gripping over the other handle portion is needed to brake it.
With reference to Figs. 5 - 7, first, externally a ring strap band 21 is fitted to make sure of a gripping by hand which is tied with a mounting end 20. Size of the band is preferable in about 20 - 25 cm in fold form. the mounting position may he changed anywhere around the handle.
