Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a baton with a collar, and in particular,
The present invention relates to a baton with a collar that can be folded down to be compactly reduced.

[0002]

2. Description of the Related Art A conventional baton baton is disclosed in, for example, Japanese Utility Model Laid-Open No. 63-90796. this is,
A baton made of a thin metal plate is attached to a baton that has a handle on one end and the other end can be expanded and contracted in the longitudinal direction. An outer peripheral groove is provided at a substantially central portion of the thickness of a rubber ring having an inner diameter and an appropriate thickness matching with the outer peripheral groove, and the outer peripheral groove is fitted into the hole of the metal plate to form a collar, and a rubber is formed. By attaching the ring made from the end of the rod to the base of the handle, the tsuba is detachably attached to the baton.

[0003]

However, in the above-described conventional baton with a collar, the brim is bulky when it is carried, so that it is difficult to urgently attach the baton if it is pulled out from the rod body and removed. Therefore, there was a problem that the tsuba was suddenly attacked by a weapon, and the tsuba could not be installed when it was necessary to deal with the sword, and it was necessary to face the baton without a tsuba.

Further, there has been a problem that the tsuba removed from the rod body is easily lost and its management is troublesome. Furthermore, instead of a light metal flange made of a thin metal plate, when a sturdy thick flange is cantilevered from the baton to one side and fixed,
There was a problem that the rubber ring for mounting was easily deformed and unstable and wobbled, making it difficult to use.

Therefore, the present invention has been made in view of such conventional problems, and an object thereof is to easily fold and compact when carrying or carrying. When using it, we provide a baton with a collar that can be raised and bulged with one touch,
It is to solve the above-mentioned conventional problems.

SUMMARY OF THE INVENTION The present invention relates to a baton with a collar provided with a collar near the base of the grip portion of the baton body, the collar having two pieces that can swing relative to each other around a central axis. It has a hinge structure in which one piece is fixed to the baton body and the other piece is formed so as to project laterally from the baton body.

[0007]

[Operation] One side of the tsuba is fixed to the baton body,
There is no risk of loss. When the other piece that is not fixed to the baton body is tilted down, it becomes almost parallel to the baton body. Therefore, for example, it can be compactly stored and held in a holder or the like, and does not get in the way.

[0008] If one of the fallen pieces is raised, it can be easily used as a baton with a collar. It is also easy to make the tsuba a sturdy and rigid structure that does not wobble or deform.

Corresponding to the stopper pin 33, two engaging recesses 35a, 35b with which the spherical head portion 33a of the stopper pin engages are displaced from the cylindrical surface of the base portion 26 of the collar piece 23 by 90 degrees at the central angle. Is formed. Explaining the baton main body 1 of this embodiment, the baton main body 1 is constituted by a plurality of (three) cylindrical bodies 5, 6, 7 of different diameters in an extendable manner. The outer cylinder 5 having the largest diameter has a front grip A fitted at its rear end and stopped by a plug 8. At least the inner surface of the distal end portion of the outer tube 5 is an inclined surface, and the inner diameter is slightly reduced toward the opening at the distal end. At least the outer surface of the rear end of the intermediate cylinder 6 housed inside the outer cylinder 5 is an inclined surface,
The outer diameter slightly increases toward the opening at the rear end. This inclined surface is adapted to engage with the inclined surface of the inner surface of the front end opening of the outer cylinder 5. Further, at least the inner surface of the tip end portion of the intermediate cylinder 6 is an inclined surface, and the inner diameter is slightly reduced toward the opening at the tip end. The inner cylinder 7 accommodated inside the intermediate cylinder 6
At least the outer surface of the rear end portion is an inclined surface, and the outer diameter slightly increases toward the opening at the rear end. The inclined surface is adapted to engage with the inclined surface of the inner surface of the tip end opening of the intermediate cylinder 6. A cap 9 is screwed onto the tip of the inner cylinder 7. The rear end of the inner cylinder 7 can be engaged with a spring or a magnet (not shown) provided near the rear end of the outer cylinder 5.

The respective cylinders 5, 6 and 7 are sequentially stored in the contracted state shown by the solid line in FIG. By gripping the front grip A and shaking the baton main body 1, the intermediate cylinder 6 and the inner cylinder 7 are shaken out by the centrifugal force and extended. At this time, the inclined surface of the outer diameter of the rear end of each cylinder is locked to the inclined surface of the inner diameter of the tip of the cylinder immediately outside and prevented from coming off. In addition, the inclination angle of each inclined surface is set so that the locking of each inclined surface can be released and contracted by applying an external force of a predetermined magnitude or more in the opposite direction to the tip portion of the baton body 1 in the extended state. Has been done. At the time of reduction, the rear end of the inner cylinder 7 is locked by a spring or a magnet inside the outer cylinder 5 to prevent accidental slipping out.

Next, the operation will be described. When the baton with a collar is transported in a compact state or is stored in a holder and carried, the collar piece 23 of the collar 20 may be tilted. At that time, the stopper pin 33 is pulled out against the bias of the coil spring 34, and the head 33 a and the base 26 of the collar piece 23 are pulled out.
The engagement with one of the engaging recesses 35a is released. Then
The collar piece 23 is pushed down by hand against the biasing force of the torsion coil spring 30. If it is rotated about 90 ° about the central axis 21, it will fall to the position shown by the chain line in FIGS. Then, the head portion of the stopper pin 33 is automatically protruded by the elastic force of the coil spring 34, and the other engaging concave portion 3 of the base portion 26.
Engage with 5b. As a result, the collar piece 23 is compactly folded and fixed along the outer cylinder 5 of the baton main body 1.

When carrying the baton, the baton body 1 is contracted. When using this baton with a collar, the collar piece 23 that has been fallen is raised. At this time, the stopper pin 33 is pulled out toward the front grip A in the same manner as described above, and the engagement between the head portion 33a and the other engagement recess 35b of the base portion 26 is released. Then, due to the elastic force of the torsion coil spring 30, the collar piece 23 automatically rotates around the central axis 21 and instantly rises up, and it rotates about 90 ° and one engaging recess 3 of the base 26.
When 5a comes to the position of the stopper pin 33, the head 33a of the stopper pin is automatically protruded to engage the engaging recess 35a.
Engage with. As a result, the collar piece 23 is fixed by projecting laterally from the baton body 1 as shown by the solid line in FIGS.

When using the baton, the front grip A at the end of the baton body 1 can be gripped, and the intermediate cylinder 6 and the inner cylinder 7 can be extended and extended to be used like a sword. The hand holding the front grip A is protected by the collar 20. In particular, the collar 20 of this embodiment has a thick and sturdy structure, can sufficiently withstand a strong impact, and does not wobble. Therefore, even when the opponent attacks with a weapon such as a powerful stick or a blade, it can be dealt with stably and reliably.

FIGS. 4 and 5 show a second embodiment. This embodiment differs from the first embodiment in that the torsion coil spring 30 of the collar 20 is omitted and the collar body 27 of the collar piece 23 is a rod. The structure is simpler and more compact. In the case of this embodiment, the dead weight of the collar piece 23 is used to raise the folded collar piece 23 without depending on the elastic force of the torsion coil spring 30 (of course, it can be manually caused). That is, hold the front grip A so that the collar 20 is below the baton body 1,
When the stopper pin 33 is pulled out rearward and the engagement with the engagement concave portion 35b is released, the flange piece 23 rotates about 90 degrees around the central axis 21 by its own weight. Then, when the knob 33b of the stopper pin 33 is released, the pin is advanced by the elastic force of the coil spring 34 and its head 33a engages with the engaging recess 35a in the base 26, so that the collar main body 27 is located on the baton main body 1 side. It is fixed in a state of overhanging.
