Description
FIELD OF THE INVENTION
[0001] The present invention relates to physical protection
devices, and in particular to a physical protection device which
can be reused many times so that the user can make exercise to have
a preferred effect without any mistake. Moreover the present
invention can be used to expel animals, such as dogs.
BACKGROUND OF THE INVENTION
[0002] Current used physical protection devices are atomized
physical protection device, which use the same principle as a
pesticide device. Stimulus liquid is filled into a high-pressure
bottle (referring to FIG. 1). A spray head is installed at an upper
end of the bottle. As the head is pressed, the liquid will spray
out so as to achieve the effect of physical protection. However in
fact, the liquid cannot be sprayed out to a far place. Thereby it
is only used in a near field. Furthermore, in spraying, due to the
effect of wind or as the devil person comes near the user so that
the liquid cannot spray to a desired position. Even it is possible
that the liquid is sprayed to the user himself (or herself).
[0003] Referring to FIGS. 2 and 2A, a prior art is illustrated. In
the prior art a plurality of bullets 50 is filled into a gun body
5. An impact element (not shown) is installed at a top cover 51. In
use, the top cover 51 is buckled to the gun body 5. When a handle
52 is pressed downwards, the bullets 50 are prepared to be
triggered and meanwhile, the emitting key 53 and the safety button
54 are pressed so that the impact unit will impact the bullet 50 to
be shot out. After shooting, the push-rod 55 is ejected to retract
the bullet 50. In above mentioned structure, the main defect is
that to press the handle 52 to fill the bullet 50 into the bore of
a gun is a laborious work, it is difficult to women or weaker.
Thereby the work of retracting the bullet is also a laborious
work.
SUMMARY OF THE INVENTION
[0004] Accordingly, the primary object of the present invention is
to provide a physical protection device, wherein the physical
protection device can be reused many times so that the user can
make exercise to have an preferred effect without any mistake as
the physical protection device is used. Moreover the present
invention can be used to expel animals, such as dogs.
[0005] To achieve above objects, the present invention provides a
physical protection device which comprises a receiving chamber
having an inner tube. At least one bullet is placed in the inner
tube. A front end of the inner tube having an opening. A top of the
receiving chamber is installed with an emitting key. Each of two
lateral side of the receiving chamber is formed with a slot and a
buckle.
[0006] The present invention further comprises a base. Each of two
sides of the front end of the base has a tenon corresponding to the
slot and an ear corresponding to the buckle. An interior of the
base is installed with a push rod. An impact unit and a stud; a
bottom of the push rod has a quick restoring spring. A rotatable
handle is pivotally installed to a bottom of the base. One end of
the rotatable handle resists against a front end of the impact unit
and another end of the rotatable handle is a free end.
[0007] Furthermore, pushing the rotatable handle to pivotally
rotate will push the impact unit to move backwards to compress the
spring to store energy. By the lock of the stud, the push rod moves
backwards due to the action of the emitting key to move axially. A
rear end of the push rod pushes the stud to unlock. The impact unit
is ejected by the resilient force of the spring so as to impact a
rear end of the spring. A rear end of the spring is formed with an
expansion chamber which is filled with powder. A front end of the
bullet is filled with liquid. A valve is installed between the
liquid and the expansion chamber.
[0008] The various objects and advantages of the present invention
will be more readily understood from the following detailed
description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION
[0018] In order that those skilled in the art can further
understand the present invention, a description will be described
in the following in details. However, these descriptions and the
appended drawings are only used to cause those skilled in the art
to understand the objects, features, and characteristics of the
present invention, but not to be used to confine the scope and
spirit of the present invention defined in the appended claims.
[0019] With reference to FIGS. 3 to 5, the physical protection
device of the present invention is illustrated. The physical
protection device has the following elements.
[0020] A receiving chamber 1 has an inner tube 10. At least one
bullet 3 is placed in the inner tube 10. A front end of the inner
tube 10 is tapered with an opening formed at a foremost thereof. A
top of the receiving chamber 1 is installed with an emitting key
11. Each of two lateral side of the receiving chamber 1 is formed
with a slot 12 and a buckle 13.
[0021] A base 2 is included. Each of two sides of the front end of
the base 2 has a tenon 22 corresponding to the slot 12 and an ear
23 corresponding to the buckle 13. An interior of the base 2 is
installed with a push rod 24, an impact unit 25 and a stud 26. A
bottom of the push rod 24 has a quick restoring spring 241. A
rotatable handle 27 is pivotally installed to a bottom of the base
2. One end of the rotatable handle 27 resists against a front end
of the impact unit 25 and another end of the rotatable handle 27 is
a free end. To push the rotatable handle 27 to pivotally rotate,
the impact unit 25 is pushed to move backwards to compress the
spring 241 to store energy. Meanwhile, by the lock of the stud
(referring to FIG. 6), the push rod 24 move backwards due to the
action of the emitting key 11 to move axially. A rear end of the
push rod 24 pushes the stud 26 to unlock. The impact unit 25 is
ejected by the resilient force of the spring 251 so as to impact a
rear end of the spring 251. A rear end of the spring 251 is formed
with an expansion chamber 31 which is filled with powder. A front
end of the bullet 3 is filled with liquid 33. The liquid 33 is
stimulus liquid or dyes. A valve 34 is installed between the liquid
33 and the expansion chamber 31. Furthermore, to have a safety
effect, two sides of the base 2 are installed with safety buttons
28 corresponding to the rear end of the push rod 24. When the
safety button 28 is pushed, the push rod 24 is released (referring
to FIG. 7). Namely, if it is desired to push the emitting key 11 to
trigger the bullet 3, the safety button 28 must be pushed so as to
further push the push rod 24 to unlock the stud 26 so that the
impact unit 25 impacts the expansion chamber 31 at the rear end of
the bullet 3 to trigger the filled powder to act. Thereby the valve
34 will extrude the liquid 33. A strong internal pressure will
destroy a front end of the bullet 3. Meanwhile the liquid 33 sprays
out from the opening of the inner tube 10.
[0022] Referring to FIGS. 8, another embodiment of the present
invention is illustrated. The inner tube 10a of the receiving
chamber la is a straight tube. A rear end of the bullet 3a is an
expansion chamber 31a. The liquid 3a is filled into an easy
breakable short cylindrical container 34a made of such as plastics
or rubber. The containers 3a is installed at a front end of the
bullet 3a. The user pushes the emitting key 11a so that the push
rod 23 pushes the stud 26 to unlock. Thereby the impact unit 25
will impact the expansion chamber 31a at the rear end of the bullet
3a to trigger the powder to act. As a result, the container 34a is
ejected out from the opening of the inner tube 10. As the container
34a impacts a devil person, he (or she) will feel ache and the
container 34a will break. The liquid 33a will spray upon the body
of the person to achieve the effect of protecting the user. This
embodiment has the effect of increasing the traveling length of the
bullet 3a. Thereby if the liquid 3a within the container 34 is dye.
It has the effect of make an indication to the devil person.
[0023] The present invention is thus described, it will be obvious
that the same may be varied in many ways. Such variations are not
to be regarded as a departure from the spirit and scope of the
present invention, and all such modifications as would be obvious
to one skilled in the art are intended to be included within the
scope of the following claims.
