Description
TITLE OF THE INVENTION
POLICE BATON WITH A GUARD
BACKGROUND OF THE INVENTION
Field of the Invention The present invention concerns a police baton with a guard and, more in particular, it relates to a police baton with a guard which can be contracted into a compact s*ate by folding the guard.
Description of the Prior Art A police baton with a guard in the prior art is dis-closed in, for example, Japanese Utility Model Laid-Open Sho 63-90796. A guard made of a thin metal plate is attached by way of a ring made of rubber to a police baton having a hilt at one end and extensible and contractible in the longi-tudinal direction at the other end. The rubber ring has an inner diameter about equal wlth the outer diameter of a baton main body near the base end and has an appropriate thickness, and the ring has an outer circumferential groove formed about at a middle portion of the thickness along the outer diametrical circumference thereof. The outer circum-ferential groove of the rubber ring is ~it into an opening perforated in the central portion of the guard, and the 2 ~ 3 guard is detachably mounted to the police baton by passing the ring from the end of the baton main body to the base end of the hilt.
In addition, so ~ar as the present inventor, et al know, there can be mentioned US Patent Nos. 5,041,951 and 1,323,973, and German Patent No. 649,578 as the technique relevant to the present invention.
Each of them has a concern with the present invention only in that a guard is disposed as a hand guard to an extensible/contractible police baton in US Patent No.
5,041,951, a hand guard is disposed to a grip portion o-f a weapon such as a sword member in US Patent No. 1,323,971 and, -~urther, a hand guard ser~ing also as a guard has such a structure that it is detached partially -from a hilt for holding a sword shank in the hilt or detaching the shank there-from ln German Patent No. 64~,578.
However, in the police baton with the guard in Japanese Utility Model Laid-Open Sho 63-90796, if the voluminous guard is kept withdrawn and detached from the baton main body during carriage, it is dif~icult to attach the guard quickly in case of an emergency. Accordingly, it in~-olves a problem that a user of the police baton can not attach the guard in a moment for imminent situation, -for example, when he su-f~ers from sudden attack by a ru-f-fian having a weapon and he is obliged to -fight against the attack with a police baton with no guard.
Further, there is a problem that the guard once detached from the baton main body is easily missing and the administration is troublesome.
Further, if a strong and thick guard is used instead of a light guard made of a thin metal plate, and it is secured being extended from one side of the police baton in a cantilever fashion, the attaching rubber ring tends *o undergo deformation, thus resulting in a problem that the guard becomes instable and jolts making it difficult to use.
In view of the above, the present invention has been accomplished taking notice on such problems in the prior art and the obJect thereo-f is to overcome the foregoing problems in the prior art by providlng a pollce baton with a guard which can be simply folded into a compact state when lt is carrled about or transported and can be turned up and extended by one touch upon use.
SUMMARY OF THE INVENTION
The present invention concerns a police baton with a guard having the guard near the base end of a gripping portion of a baton main body, wherein the guard o-f a certain length is attached by way of a hinge mechanism to a baton maln body at one end thereof such that the guard can rotate around a central axis of the hinge mechanism and adapted L ~
such that it can project sideway -from the baton main body or can be folded toward the baton main body at the other end thereo-~ and the guard has a holding mechanism ~or holding the guard in a state pro;ected from the baton main body.
In a preferred embodiment, the holding mechanism may comprise a torsion coil spring and resiliently biases the guard in the protruding direction by the spring.
In another preferred embodiment, the holding mechanism may comprise a stopper pin that projects under the resiliency of a spring and two engaging notches formed at the circum-ferential sur~ace of a base of the guard pivoted to the hinge mechanism, being spaced apart ~rom each other by an angle of 90 for receiving the projecting stopper pin.
In a further preferred embodiment, the guard may be attached to the police baton by means of an attaching/~ixing member, which is made o-f a metal plate formed into a T-shaped configuratlon by press molding to ~orm right and le-ft arms and a bottom, and a sleeve is -formed to the bottom to con-stitute a bearing for pivoting the guard, and the holding mechanism comprises elastically deformable engaging fingers formed by bending the right and left arms.
The sleeve may be -formed by cylindrically bendlng the press-molded bottom.
In a -further pre~erred embodiment, the guard is -formed by bending a metal rod into two portions, in which trunnions `3 ~
are formed at both ends thereo-f to constitute a hinge by bending and the trunnions are inserted and held in the sleeve.
In these ways, the guard is secured by one of the members to the side of the baton main body and thus free from the worry of missing.
When one of the members not fixed on the side of the baton main body is turned down, the guard is substantially in parallel with the katon main body. Accordingly, it can be contained and held in a compact means, for example, in a holder to be not in the way.
When the turned down msmber of the guard is raised, it can be used simply as a police baton with a guard. It is also easy to constitute the guard by a strong rigid structure, and it neither jolts nor deforms.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention wlll now be described for pre-ferred embodiments thereof with re-ference to the drawings.
Fig. 1 through Flg. 3 show a first embodiment according to the present invention. In the figures, reference numeral 1 denotes a baton main body. A guard 20 is disposed at a position localized from the longitudinal center to one end of the baton main body 1, that is, at a position near the base end of a gripplng portion or a hilt A at the end of the baton main body 1.
The guard 20 of this embodiment has a hinge structure capable of rotationally turning up and down around a central shaft 21. The structure comprises two members, one being an attaching/fixing member 22 and the other being a guard member 23, and both of them are assembled to each other by the central shaft 21.
Description will be made more specifically to the structure of the guard ~0 with reference to Fig. 2.
As shown in the figures, the attaching/fixing member 2~ comprises a bottom 22a, right and left side walls 22b that stand vertically opposing to each other at the upper surface of the bottom 22a and a rear wall 2~c for joining the rear portions of both of the side walls 22a. The space surrounded with the wall surfaces opens upward and forward to define a guard member attaching space 24. A
shaft hole 25 (as shown in Figs. 1 and 3) is disposed to the wall surface of each of the side walls 22a. The bottom 22a of the attaching/fixing member 22 has a lower surface formed into an arcuate shape, which is secured by means of welding or the like in a close contact with the outer circumferential surface of an axially extended ring member 4. The ring member 4 is fit to the outer circum-ferential surface o~ the baton main body 1 before mounting the hilt A and then urging the ring as far as a position near the base end of the hilt A mounted thereafter for securlng there.
The guard member 23 comprises a cylindrical base 26 $~
and a thick guard body 27 slightly curved and extended from the outer circumference of the base 26 in the direction of a tangential line. A spring groove 28 is formed to the front surface of the guard member 23, such that the groove is gradually made greater from the top end of the guard body 27 to the front surface of the base 26.
As especially shown in Fig. 3, the base 26 of the guard member 23 is fit into the guard member attaching space 24 of the attaching/fixing member 22 and a torsion coil spring 30 as a resilient member is mounted in the spring groove 28 of the guard member 23. A central shaft 21 is passed through the shaft hole 25 from the outside of the side wall 22a on one side of the attaching/fixing member 22 and, further, passed through the axial center of the base 26 of the guard member and the coiled portion of -the torsion coil spring 30 and inserted into the shaft hole 25 from the inner side of the side wall 22a on the opposing side, by which the guard member 23 is swingeably attached to the attaching/~ixing member 22. A retaining ring 31 is mounte~
to each of the ends of the central shaft 21 for preventing the shaft from slipping off.
The torsion coil spring 30 is in press contact at one arm 30a with the bottom of the spring groo~e 28 of the guard member 23 and in press contact at the end of the other arm 30b with the upper surface of the bottom 22a of 3 ~
the attaching/fixing member 22.
Further, a through hole 32 (in Fig. 2) is formea in a forward-to-backward direction about at the central portion of the rear wall 22c of the attaching/fixing member 22.
stopper pin 33 is mounted together with a compression coil spring 34 in the through hole 32. The top end of the stopper 33 is formed as a spherical head 33a having a greater dia-meter than that of the pin shaft, while a knob (or hook-like finger rest) 33b is provided to the rear end.
Engaging notches 35a and 35b are formed to the cylin-drical surface of the base 26 of the guide member 23 being displaced from each other at an angle of 90 relative to the center o~ the cylinder, for engaging the spherical head 33a of the stopper pin 33.
Referring then to the baton main body 1 of this embo-diment in Fig. 1, it comprises a plurality (three in this embodiment) of cylindrical member 5, 6, 7 each having a different diameter and combined in a telescopic structure.
The outer cylindèr 5 of the largest diameter has the hilt A fit-ted into the rear end and secured by a plug 8. The top end of the outer cylinder 5 has an inclined surface at least at the inner surface and the inner diameter is slightly reduced -toward the opening at the top end. The intermediate cyllnder 6 contained at the ~nside of the outer cylinder 5 has an inclined surface on the side of ~?~
the rear end at least at the outer surface, and the outer diameter is slightly enlarged toward the opening at the rear end. The inclined surface engages the inclined sur-face formed at the inner surface G~ the opening at the top end of the outer cylinder 5~ Further, the top end of the intermediate cylinder 6 has an inclined surface formed at least at the inner surface thereof and the inner diameter is slightly reduced toward the opening of the top end. An inner cylinder 7 contalned at the inside o~ the intermediate cylinder 6 has an inclined surface formed at least at the outer surface on the side of the rear end and the outer diameter thereof is slightly enlarged toward the opening o-f the rear end. The inclined sur-face engages the inclined surface at the inner surface of the opening at the top end of the intermediate cylinder 6. A cap 9 is screwed to the top end of the inner cylinder 7. The inner cylinder 7 can engage at its rear end to a spring or a magnet (not illus-trated) disposed to the inside near the rear end of the outer cylinder 5.
In a contracted state shown by the solid line in Fig. 1, each of the cylinder 5, 6 and 7 is contained successively.
When a user swings the baton main body 1 by gripping the hilt A, the intermediate cylinder 6 and the inner cylinder ?
7 are thrusted and e~tended outward by the centrifugal force. In this case, the inclined surface at the rear end of each of the cylinders engages the inclined sur-~ace on the inner diameter at the top end o-f the cylinder situated just outside thereof and is inhibited from slipping off.
The angle of inclination for each o~ the inclined surfaces is set such that engagement between each of the inclined surfaces is released to enable contraction by applying an external force greater than a predetermined level in the opposite direction to the top end of the baton main body 1 in the extended state. It is designed such that the.rear end of the ~nner cylinder 7 engages the spring or the magnet at the inside of the outer cylinder 5 to prevent it from accldentally slipping off.
When the guard baton with the guard is transported or carried about by being contained in a holder in a compact state, the guard member 23 of the guard 20 is turned down.
In this casel the stopper pin 33 ics pulled out against the resiliency of the coil spring 34 to release engagement between the head 33a of the stopper pin 33 and the engaging notch 35a o~ the base 26 of the guard member 23. Then, the guard member 23 is manually turned down against the resili-ency of the torsion coil spring 30. When the guard member 23 is rotated by about 90 around the central shaft 21, it turns down to a posi-tion as shown by the dotted chain in Figs. 1 and 2. Then, the head of the stopper pin 33 automa-tically proJects by the resiliency of the coil spring 34 and ~9~ $
engages the other engagin~ notch 35b of the base 26. Thus, the guide member 23 is folded into a compact state and secured along the outer cylinder 5 of the baton main body 1.
When the baton main body 1 is to be carried about it is contracted in this way.
Upon using the police baton with the guard, the turned down guard member 23 is raised. In this case, the stopper pin 33 is pulled out in the direction of the hilt A as described above, to release the engagement between the head 33a of the stopper pin 33 and the other engaging recesses 35b o~ the base Z6. Then, the guard member 23 rotates automatically around the cen-tral sha-ft 21 by the resillency of the torsion coil spring 30 to turn-up in a moment. Then. when it rotates by about 90 to a position in which the engaging notch 35a o~ the base 26 reaches the position corresponding to the stopper pin 33, the head 33a of the stopper pin 33 automatically projects to engage the engaging recess 35a. Thus, $he guard member 23 extends s~deway -~rom the baton main body 1 and is secured as shown by the solid line in Figs. 1 and 2.
A user can use the guard baton main body like a sword by gripping the hilt A at the end of the baton main body 1 and thrusting to extend the intermediate cylinder 6 and the inner cylinder 7.
The hand ~ripping the hilt ~ is protected by the guard :
20. Particularly, since the guard 20 of this embodiment is thick and strong, it can sufficiently withstand strong impact and does not Jolt. Accordingly, if an opponent attacks with a weapon such as a powerful club or cutlery, the user can surely cope with the attack stably.
Figs. 4 and 5 show a second embodiment.
This embodiment ls different from the first embodiment described above in that the -torsion coil spring 30 ~or the guard 20 is omitted and the guard body 27 of the guard member 23 is made as a solid rod. The structure is made more simple and compact.
In this embodiment, the turned down guard member 23 is raised not by the resiliency of the torsion coil spring but due to the own weight of the guard member 23 (o-f course it can be manually turned up). That is, when a user grips the hilt ~ with the guard 20 being on the lower side of the baton main body 1 and pulls the stopper pin 33 backward to release the engagem~nt between the stopper pin 33 and the engaging notch 35b, the guard member 23 rotates by its own weight about by 90 around the central shaft 21. Then, if t~e knob 33b of the stopper pin 33 is released, the stopper pin 33 advances by the resiliency of the coil spring 34, by whlch the head 33a of the pin 33 engages the base 26 at the engaging notch 35a, and the guard body 27 is secured ln a state being extended sideway of the baton main body 1.
Fig. 6 shows a third embodiment of the invention.
In this embodiment, a guard 20 is formed by using a plate material. An attaching/fixing member 22 is fabri-cated from a metal plate by press molding it into a struc-ture comprising a bottom 22a and a vertically erected T-shaped rear wall 22c. A sleel~e 40 is welded to the base of the rear wall 22c. Both of right and left arms of the T-shaped rear wall 22c are bent forward to form elastically deformable engaging fingers 22d. The bottom 22a is welded to the outer circumferential surface of a ring member 4.
A guard member 23 is formed also from a metal plate by press molding it into a guard body 27 and further, cylindrically bending a base end into a base 26 having a shaft hole 41.
The shaft hole for the base 26 of the guard member 23 and that for the sleeve 40 of the attaching/fixing member 22 are al.lgned with each other, through which a central sha~t 21 ~s passed and prevented ~rom slipping of~ by split pins ~3, to assemble the guard 20.
The turned down guard member 23 is raised and rotated by about 90 around the central shaft 21 and urged against the T-shaped rear wall 22c of the attaching/fixing member 22 to resiliently diverge the engaging fingers 22d. Both sides of the guard body 27 are put between the engaging fingers 22d, to secure the guard body 27 in a state extended - , ~3~$~33 sideway from the baton main body 1.
The guard 20 has a merit that it can be mass produced at a reduced cost by press molding and it is light in weight and can be used simply.
Fig. 7 shows a fourth embodiment.
In this embodiment, a guard member 23 of a guard 20 is formed by bending a metal rod, and the base end of the rod is bent sideway to form a central shaft 21.
The attaching/fixing member 22 is also a press molding product like that in the third embodiment. A portion of the attaching/fixing member 22 is cylindrically bent to form a shaft hole 45 for the central shaft 21. The guard 20 is assembled by inserting the central shaft 21 to the shaft hole 45 by utilizing the resiliency of the guard member 23.
The turned-up guard member 23 i9 urged to the T-shaped rear wall 22c of the attaching/fixing member 22 to resi-liently diverge the engaging fingers 22d and both sides of the guard body 2i are put between the engaging fin~ers 22d, and the guard body 27 is secured in a state being extended sideway from the baton main body 1 llke that in the third embodiment.
The guard member 20 can also be mass produced at a reduced cost, as well as it is reduced in the weight and convenient to use.
As has been described above, in the police baton with the guard according to the present invention, the guard has two members which are rotationally movable to each other around the central shaft as a hinge structure in which one of the members is secured to the baton main body, while the other of the members is formed such that it can project sideway from the baton main body. Accordingly, the follo-wing advantageous effects can be obtained.
(1) The guard is free from the worry of missing and can be administrated easily. (2) The guard can be folded into a compact state simply upon carriage or transportation.
(3) The guard can be turned-up in one touch upon use, which enables to take quick countermeasure upon emergency.
POLICE BATON WITH A GUARD
BACKGROUND OF THE INVENTION
Field of the Invention The present invention concerns a police baton with a guard and, more in particular, it relates to a police baton with a guard which can be contracted into a compact s*ate by folding the guard.
Description of the Prior Art A police baton with a guard in the prior art is dis-closed in, for example, Japanese Utility Model Laid-Open Sho 63-90796. A guard made of a thin metal plate is attached by way of a ring made of rubber to a police baton having a hilt at one end and extensible and contractible in the longi-tudinal direction at the other end. The rubber ring has an inner diameter about equal wlth the outer diameter of a baton main body near the base end and has an appropriate thickness, and the ring has an outer circumferential groove formed about at a middle portion of the thickness along the outer diametrical circumference thereof. The outer circum-ferential groove of the rubber ring is ~it into an opening perforated in the central portion of the guard, and the 2 ~ 3 guard is detachably mounted to the police baton by passing the ring from the end of the baton main body to the base end of the hilt.
In addition, so ~ar as the present inventor, et al know, there can be mentioned US Patent Nos. 5,041,951 and 1,323,973, and German Patent No. 649,578 as the technique relevant to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention wlll now be described for pre-ferred embodiments thereof with re-ference to the drawings.
Fig. 1 through Flg. 3 show a first embodiment according to the present invention. In the figures, reference numeral 1 denotes a baton main body. A guard 20 is disposed at a position localized from the longitudinal center to one end of the baton main body 1, that is, at a position near the base end of a gripplng portion or a hilt A at the end of the baton main body 1.
The guard 20 of this embodiment has a hinge structure capable of rotationally turning up and down around a central shaft 21. The structure comprises two members, one being an attaching/fixing member 22 and the other being a guard member 23, and both of them are assembled to each other by the central shaft 21.
Description will be made more specifically to the structure of the guard ~0 with reference to Fig. 2.
As shown in the figures, the attaching/fixing member 2~ comprises a bottom 22a, right and left side walls 22b that stand vertically opposing to each other at the upper surface of the bottom 22a and a rear wall 2~c for joining the rear portions of both of the side walls 22a. The space surrounded with the wall surfaces opens upward and forward to define a guard member attaching space 24. A
shaft hole 25 (as shown in Figs. 1 and 3) is disposed to the wall surface of each of the side walls 22a. The bottom 22a of the attaching/fixing member 22 has a lower surface formed into an arcuate shape, which is secured by means of welding or the like in a close contact with the outer circumferential surface of an axially extended ring member 4. The ring member 4 is fit to the outer circum-ferential surface o~ the baton main body 1 before mounting the hilt A and then urging the ring as far as a position near the base end of the hilt A mounted thereafter for securlng there.
The guard member 23 comprises a cylindrical base 26 $~
and a thick guard body 27 slightly curved and extended from the outer circumference of the base 26 in the direction of a tangential line. A spring groove 28 is formed to the front surface of the guard member 23, such that the groove is gradually made greater from the top end of the guard body 27 to the front surface of the base 26.
As especially shown in Fig. 3, the base 26 of the guard member 23 is fit into the guard member attaching space 24 of the attaching/fixing member 22 and a torsion coil spring 30 as a resilient member is mounted in the spring groove 28 of the guard member 23. A central shaft 21 is passed through the shaft hole 25 from the outside of the side wall 22a on one side of the attaching/fixing member 22 and, further, passed through the axial center of the base 26 of the guard member and the coiled portion of -the torsion coil spring 30 and inserted into the shaft hole 25 from the inner side of the side wall 22a on the opposing side, by which the guard member 23 is swingeably attached to the attaching/~ixing member 22. A retaining ring 31 is mounte~
to each of the ends of the central shaft 21 for preventing the shaft from slipping off.
The torsion coil spring 30 is in press contact at one arm 30a with the bottom of the spring groo~e 28 of the guard member 23 and in press contact at the end of the other arm 30b with the upper surface of the bottom 22a of 3 ~
the attaching/fixing member 22.
Further, a through hole 32 (in Fig. 2) is formea in a forward-to-backward direction about at the central portion of the rear wall 22c of the attaching/fixing member 22.
stopper pin 33 is mounted together with a compression coil spring 34 in the through hole 32. The top end of the stopper 33 is formed as a spherical head 33a having a greater dia-meter than that of the pin shaft, while a knob (or hook-like finger rest) 33b is provided to the rear end.
Engaging notches 35a and 35b are formed to the cylin-drical surface of the base 26 of the guide member 23 being displaced from each other at an angle of 90 relative to the center o~ the cylinder, for engaging the spherical head 33a of the stopper pin 33.
Referring then to the baton main body 1 of this embo-diment in Fig. 1, it comprises a plurality (three in this embodiment) of cylindrical member 5, 6, 7 each having a different diameter and combined in a telescopic structure.
The outer cylindèr 5 of the largest diameter has the hilt A fit-ted into the rear end and secured by a plug 8. The top end of the outer cylinder 5 has an inclined surface at least at the inner surface and the inner diameter is slightly reduced -toward the opening at the top end. The intermediate cyllnder 6 contained at the ~nside of the outer cylinder 5 has an inclined surface on the side of ~?~
the rear end at least at the outer surface, and the outer diameter is slightly enlarged toward the opening at the rear end. The inclined surface engages the inclined sur-face formed at the inner surface G~ the opening at the top end of the outer cylinder 5~ Further, the top end of the intermediate cylinder 6 has an inclined surface formed at least at the inner surface thereof and the inner diameter is slightly reduced toward the opening of the top end. An inner cylinder 7 contalned at the inside o~ the intermediate cylinder 6 has an inclined surface formed at least at the outer surface on the side of the rear end and the outer diameter thereof is slightly enlarged toward the opening o-f the rear end. The inclined sur-face engages the inclined surface at the inner surface of the opening at the top end of the intermediate cylinder 6. A cap 9 is screwed to the top end of the inner cylinder 7. The inner cylinder 7 can engage at its rear end to a spring or a magnet (not illus-trated) disposed to the inside near the rear end of the outer cylinder 5.
In a contracted state shown by the solid line in Fig. 1, each of the cylinder 5, 6 and 7 is contained successively.
When a user swings the baton main body 1 by gripping the hilt A, the intermediate cylinder 6 and the inner cylinder ?
7 are thrusted and e~tended outward by the centrifugal force. In this case, the inclined surface at the rear end of each of the cylinders engages the inclined sur-~ace on the inner diameter at the top end o-f the cylinder situated just outside thereof and is inhibited from slipping off.
The angle of inclination for each o~ the inclined surfaces is set such that engagement between each of the inclined surfaces is released to enable contraction by applying an external force greater than a predetermined level in the opposite direction to the top end of the baton main body 1 in the extended state. It is designed such that the.rear end of the ~nner cylinder 7 engages the spring or the magnet at the inside of the outer cylinder 5 to prevent it from accldentally slipping off.
When the guard baton with the guard is transported or carried about by being contained in a holder in a compact state, the guard member 23 of the guard 20 is turned down.
In this casel the stopper pin 33 ics pulled out against the resiliency of the coil spring 34 to release engagement between the head 33a of the stopper pin 33 and the engaging notch 35a o~ the base 26 of the guard member 23. Then, the guard member 23 is manually turned down against the resili-ency of the torsion coil spring 30. When the guard member 23 is rotated by about 90 around the central shaft 21, it turns down to a posi-tion as shown by the dotted chain in Figs. 1 and 2. Then, the head of the stopper pin 33 automa-tically proJects by the resiliency of the coil spring 34 and ~9~ $
engages the other engagin~ notch 35b of the base 26. Thus, the guide member 23 is folded into a compact state and secured along the outer cylinder 5 of the baton main body 1.
When the baton main body 1 is to be carried about it is contracted in this way.
Upon using the police baton with the guard, the turned down guard member 23 is raised. In this case, the stopper pin 33 is pulled out in the direction of the hilt A as described above, to release the engagement between the head 33a of the stopper pin 33 and the other engaging recesses 35b o~ the base Z6. Then, the guard member 23 rotates automatically around the cen-tral sha-ft 21 by the resillency of the torsion coil spring 30 to turn-up in a moment. Then. when it rotates by about 90 to a position in which the engaging notch 35a o~ the base 26 reaches the position corresponding to the stopper pin 33, the head 33a of the stopper pin 33 automatically projects to engage the engaging recess 35a. Thus, $he guard member 23 extends s~deway -~rom the baton main body 1 and is secured as shown by the solid line in Figs. 1 and 2.
A user can use the guard baton main body like a sword by gripping the hilt A at the end of the baton main body 1 and thrusting to extend the intermediate cylinder 6 and the inner cylinder 7.
The hand ~ripping the hilt ~ is protected by the guard :
20. Particularly, since the guard 20 of this embodiment is thick and strong, it can sufficiently withstand strong impact and does not Jolt. Accordingly, if an opponent attacks with a weapon such as a powerful club or cutlery, the user can surely cope with the attack stably.
Figs. 4 and 5 show a second embodiment.
This embodiment ls different from the first embodiment described above in that the -torsion coil spring 30 ~or the guard 20 is omitted and the guard body 27 of the guard member 23 is made as a solid rod. The structure is made more simple and compact.
In this embodiment, the turned down guard member 23 is raised not by the resiliency of the torsion coil spring but due to the own weight of the guard member 23 (o-f course it can be manually turned up). That is, when a user grips the hilt ~ with the guard 20 being on the lower side of the baton main body 1 and pulls the stopper pin 33 backward to release the engagem~nt between the stopper pin 33 and the engaging notch 35b, the guard member 23 rotates by its own weight about by 90 around the central shaft 21. Then, if t~e knob 33b of the stopper pin 33 is released, the stopper pin 33 advances by the resiliency of the coil spring 34, by whlch the head 33a of the pin 33 engages the base 26 at the engaging notch 35a, and the guard body 27 is secured ln a state being extended sideway of the baton main body 1.
Fig. 6 shows a third embodiment of the invention.
In this embodiment, a guard 20 is formed by using a plate material. An attaching/fixing member 22 is fabri-cated from a metal plate by press molding it into a struc-ture comprising a bottom 22a and a vertically erected T-shaped rear wall 22c. A sleel~e 40 is welded to the base of the rear wall 22c. Both of right and left arms of the T-shaped rear wall 22c are bent forward to form elastically deformable engaging fingers 22d. The bottom 22a is welded to the outer circumferential surface of a ring member 4.
A guard member 23 is formed also from a metal plate by press molding it into a guard body 27 and further, cylindrically bending a base end into a base 26 having a shaft hole 41.
The shaft hole for the base 26 of the guard member 23 and that for the sleeve 40 of the attaching/fixing member 22 are al.lgned with each other, through which a central sha~t 21 ~s passed and prevented ~rom slipping of~ by split pins ~3, to assemble the guard 20.
The turned down guard member 23 is raised and rotated by about 90 around the central shaft 21 and urged against the T-shaped rear wall 22c of the attaching/fixing member 22 to resiliently diverge the engaging fingers 22d. Both sides of the guard body 27 are put between the engaging fingers 22d, to secure the guard body 27 in a state extended - , ~3~$~33 sideway from the baton main body 1.
The guard 20 has a merit that it can be mass produced at a reduced cost by press molding and it is light in weight and can be used simply.
Fig. 7 shows a fourth embodiment.
In this embodiment, a guard member 23 of a guard 20 is formed by bending a metal rod, and the base end of the rod is bent sideway to form a central shaft 21.
The attaching/fixing member 22 is also a press molding product like that in the third embodiment. A portion of the attaching/fixing member 22 is cylindrically bent to form a shaft hole 45 for the central shaft 21. The guard 20 is assembled by inserting the central shaft 21 to the shaft hole 45 by utilizing the resiliency of the guard member 23.
The turned-up guard member 23 i9 urged to the T-shaped rear wall 22c of the attaching/fixing member 22 to resi-liently diverge the engaging fingers 22d and both sides of the guard body 2i are put between the engaging fin~ers 22d, and the guard body 27 is secured in a state being extended sideway from the baton main body 1 llke that in the third embodiment.
The guard member 20 can also be mass produced at a reduced cost, as well as it is reduced in the weight and convenient to use.
As has been described above, in the police baton with the guard according to the present invention, the guard has two members which are rotationally movable to each other around the central shaft as a hinge structure in which one of the members is secured to the baton main body, while the other of the members is formed such that it can project sideway from the baton main body. Accordingly, the follo-wing advantageous effects can be obtained.
(1) The guard is free from the worry of missing and can be administrated easily. (2) The guard can be folded into a compact state simply upon carriage or transportation.
(3) The guard can be turned-up in one touch upon use, which enables to take quick countermeasure upon emergency.
(4) The guard is stable and can be used easily with no jolting.
