Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a punchbag that can be
filled with water and air to adjust a required weight of the
punchbag whereby the punchbag has an excellent rebound and
simulates well the impact of blows on a human body.
[0003] 2. Description of Related Art
[0004] A conventional punchbag as shown in FIG. 4 comprises a bag
(30) suspended by three chains (31) at a top hem of the bag (30). A
hook (32) is engaged with distal ends of the three chains (31) and
is attached to a suitable place of a ceiling or other high places.
The bag (30) is filled with stuffing (33) such as coarse cotton or
chopped tires, and the chopped tires can enhance a weight of the
punchbag.
[0005] However, several disadvantages exist in this conventional
punchbag and are listed as following:
[0006] 1. Difficulty in transportation: Because the bag (30) is
filled with coarse cotton and chopped tires, a finished product of
the conventional punchbag not only takes up a lot of space but also
has a cumbersome weight when it is transported.
[0007] 2. Inconvenience in storage:
[0008] The conventional punchbag can not be folded or reduced after
use, therefore it is inconvenient for storage.
[0009] 3.No sense of reality:
[0010] The stuffing (33) inside the bag (30) is composed of coarse
cotton and chopped tires, and both materials have bad elasticity
and bad rebound, and therefore punching the conventional punchbag
can not give the authenticity of fighting with a real opponent.
[0011] For those sakes and to overcome the shortcomings, the
present invention tends to provide a punchbag to mitigate and
obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0012] The main objective of the invention is to provide a punchbag
that has an inner bag and an outer bag, and these two bags can be
separated from each other and folded respectively whereby the
punchbag is easily stored.
[0013] Another objective of the invention is to provided a punchbag
wherein the inner bag is divided into a water chamber and an air
chamber, therefore the inner bag is filled with water and air to
make the punchbag have excellent rebound.
[0014] Still another objective of the invention is to provide a
punchbag that makes a user to have a sense of reality while
punching it.
[0015] Other objects, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0016] FIG. 1 is an exploded view of a punchbag of this
invention;
[0017] FIG. 2 is a cross-sectional view of a water outlet on an
inner bag of the punchbag in accordance with FIG. 1;
[0018] FIG. 3 is a cross-sectional view of the assembled punchbag;
and
[0019] FIG. 4 is a perspective view of a conventional punchbag.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
[0020] As shown in FIGS. 1 and 2, a punchbag is composed of an
outer bag (10), an inner bag (20) disposed inside the outer bag
(10), and a retaining device (30).
[0021] The outer bag (10) is made of a soft material such as cloth
and has an open end (11) defined in a top face and a lid (14)
matched with the open end (11). The lid (14) is combined with a top
hem (13) of the outer bag (10) by a zipper (15) to cover the open
end (11).
[0022] The inner bag (20) is concentrically divided into an outer
water chamber (21) and an inner air chamber (22). The water chamber
(21) has an inclined top face (23). A water outlet (24) is defined
in the inclined top face of the water chamber (21) and a water plug
(25) is securable in the water outlet (24) to provide access to and
closure of the water chamber (21). Additionally, as shown in FIG.
2, the water outlet (24) has a valve plate (28) hinged to an inner
wall thereof on the inclined top face of the water chamber (21) to
enhance the anti-leaking ability. The air chamber (22) has an air
outlet (26) defined in a top surface of the air chamber (22). An
air plug (27) corresponding to the air outlet (26) is securable to
the top surface of the air chamber (22) to allow inflation of and
seal of the air chamber (22).
[0023] The retaining device (30) comprising four belts (31) are
evenly connected with an outside periphery of the outer bag (10) at
first ends, and each belt (31) has a half-moon ring (32) at a
second end to connect with a group of chains (33). A hook (34) is
secured at a top of the chains (33).
[0024] In assembly of the punchbag, the unstuffed inner bag (20) is
put inside the outer bag (10) first. Then water is poured into the
water chamber (21) via the water outlet (24) until the water fills
half capacity of the water chamber (21) and the water plug (25) is
inserted into the water outlet (24). Next, air is pumped into the
air chamber (22) to make the air chamber (22) totally expand, and
at the same time, the water inside the water chamber (21) is
squeezed by a force of the expanded air chamber (22) and rises to a
top of the water chamber (21). Finally, the air plug (27) is
mounted on the air inlet (26) to seal the air chamber (22).
[0025] After completely filling the inner bag (20), the lid (14) of
the outer bag (10) is joined with the top hem (13) by zipping the
zipper (15) and then the whole punchbag can be hung at a required
place by the hook (34) and the chains (33). A quantity of the water
poured inside the water chamber (21) controls both an ideal weight
and a softness/hardness of the punchbag to make the punching
realistic. Moreover, the valve plate (28) formed on the inner wall
of the water outlet (24) seals the water chamber (21) tightly and
prevents water from spurting out when the punchbag is punched
violently.
[0026] According to the above description, several advantages are
concluded as in the following list:
[0027] 1. Easily transported:
[0028] The outer bag (10) and the inner bag (20) can be separated
from each other and folded when the inner bag (20) is not stuffed
with air and water, so that this invention is easily
transported.
[0029] 2. Conveniently stored:
[0030] The stuffing inside the inner bag (20), the water and the
air, are easily squeezed out of the water chamber (21) and the air
chamber (22), therefore the punchbag is conveniently stored after
releasing the stuffing.
[0031] 3. Authenticity:
[0032] The weight and rebounding force of the punchbag achieved by
pouring different quantities of the water into the water chamber
(21) result in a sense of punching a real opponent.
[0033] It is to be understood that this invention is practical and
beneficial for user and manufacturer. However, although numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention. The disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the fill extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
