ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a telescopic baton, and more particularly to a telescopic baton having an easily mountable elastic multi-claw retaining means for effectively holding a fully telescoped shaft of the baton in place. The retaining means enables the telescopic baton to be assembled at reduced time and labor cost, and the shaft of the baton to be more stably held in a fully telescoped position.
FIG. 1
illustrates a conventional telescopic baton that mainly includes a hollow handle
1
, a shaft
2
adapted to slide into the handle
1
, and a fixing cap
3
screwed to a rear open end of the handle
1
. An elastic plate is bent into an elastic closed loop
31
and then fixed with a rivet or screw
32
to a front end of the fixing cap
3
. An inner diameter
21
of a rear end portion of the shaft
2
gradually increases rearward so that the shaft
2
has a flared inner wall
22
at the rear end portion. When the shaft
2
is fully telescoped into the handle
1
, the flared inner wall
22
of the rear end of the shaft
2
would fitly engage with an outer periphery of the elastic closed loop
31
and be held in place in the handle
1
. To extend the shaft
2
from the handle
1
, simply hold and forcefully swing the handle
1
. At this point, the shaft
2
, due to its own weight, would disengage from the elastic closed loop
31
to slide out of the handle
1
. The following are some disadvantages of the telescopic baton of FIG.
1
:
1. Since the elastic plate is in the form of a closed loop, it is uneasy to align the rivet or screw
32
with a hole
33
provided at a front end surface of the fixing cap
3
to fix the elastic closed loop
31
to the fixing cap
3
. More efforts and time are needed to complete the assembling of the elastic closed loop
31
to the fixing cap
3
to increase the manufacturing cost of the telescopic baton.
2. The elastic closed loop
31
fixed to the fixing cap
3
projects forward from the fixing cap
3
and makes it more difficult to screw or loosen the fixing cap
3
onto or from the rear end of the handle
1
. The elastic closed loop
31
is easily subject to deformation due to unexpected falling and/or collision with some other articles before the fixing cap
3
has been mounted into the rear end of the handle
1
. And a deformed elastic closed loop
31
is not easily aligned with and extended into the rear end of the shaft
2
to firmly hold the shaft
2
in a telescoped position.
3. The elastic closed loop
31
has a curved and smooth outer periphery and there are only two contact points between the elastic closed loop
31
and the inner diameter
21
of the shaft
2
when the shaft
2
engages with the loop
31
, therefore, the shaft
2
could not be stably and firmly held in the handle
1
by the elastic closed loop
31
. The shaft
2
in the telescoped position tends to unexpectedly slide out of the handle
1
.
It is therefore tried by the inventor to develop an improved telescopic baton having a multi-claw retaining means that can effectively hold a shaft of the baton in a fully telescoped position and be easily and safely mounted in an inner space defined by a fixing cap of the baton.
SUMMARY OF THE INVENTION
A primary object of the present invention is to provide a telescopic baton having an elastic multi-claw retaining means for effectively holding a shaft of the baton in a fully telescoped position. The elastic multi-claw retaining means may be easily punched into a cylindrical fixing cap of the baton by a suitable means. No efforts are needed to align any fastening means with any fixing hole to mount the elastic multi-claw retaining means into the fixing cap. The telescopic baton can therefore be more easily assembled at reduced time and labor cost.
Another object of the present invention is to provide a telescopic baton having an elastic multi-claw retaining means that firmly and evenly grips a shaft of the baton fully telescoped into a hollow handle of the baton from more than two different radial directions, so that the telescoped shaft is not easily separated from the claws of the retaining means to slide out of the handle of the baton.
