Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is related to an adjustable punching
bag and particularly to a punching bag, which provides adjustable
weight and hardness and is able to be folded for packing, storing
and delivering conveniently.
[0003] 2. Brief Description of the Related Art
[0004] The punching bag is frequently used during practicing skill
of art of attack and defense. In order to meet different personal
needs, punching bags in different weights are available for being
chosen as desired. However, it is known that a lot of punching bags
have to be prepared and the volumes of the punching bags are huge
such that problems with regard to storage, packing and delivery in
addition to handling cost are worth us to care.
[0005] As the foregoing, the conventional punching bag occupies
limited space, requires high delivery cost. And, it is unable for
the user to adjust weight thereof suitable for personal practice
habit and load carrying ability. How to solve the preceding
problems is a subject has to be overcome.
SUMMARY OF THE INVENTION
[0006] An object of the present invention is to provide an
adjustable punching bag to improve deficiencies of being not
possible for weight adjusting, packing and storing.
[0007] Another object of the present invention is to provide an
adjustable punching bag, with which it is not necessary for
manufactures to fabricate punching bags in different weights and to
worry about unsold punching bags in stocks.
[0008] In order to achieve the preceding objects, the adjustable
punching bag of the present invention includes an inner bag set and
an outer jacket bag. The outer jacket bag provides an inlet for
receiving the inner bag set. The inner bag set includes a first
inner bag, a second inner bag and multiple daughter bags. The
second inner bag and the daughter bags are filled with stuffing and
placed in the outer jacket bag sequentially. The stuffing provides
with gradients in different densities for controlling weight of the
entire punching bag. The stuffing can be liquid, solid or gas.
Liquid can be water, liquids in different specific weights or
curdled glue formed of water with agent. Solid can be plastic air
bag or lead blocks, which affect weight. Gas is capable of
occupying space for decreasing weight. Even more, the stuffing can
be any mixture of liquid, gas and solid. Thus, the weight of the
punching bag is under control and the required weight can be
obtained and precise training of skill with regard to art of attack
and defense can be achieved. The cap knob at the top of the second
inner bag can be removed to take out the daughter bags or the cap
knob at the bottom of the second inner bag can be removed to
release the stuffing completely. Further, the outer jacket bag and
the inner bag set can be folded and stored in a box simply for
being carried with the user conveniently.

DETAILED DESCRIPTION OF THE INVENTION
[0021] Referring to FIGS. 1 to 3, an adjustable punching bag
apparatus of the present invention includes an inner bag set and an
outer jacket bag 30. The outer jacket bag 30 provides several
pieces of metal chains 31 and a tying cord 32 at the upper end
thereof. The inner bag set includes a first inner bag 10, a second
inner bag 20 and a plurality of daughter bags 23.
[0022] Wherein, the outer jacket bag 30 receives the inner bag set
and the metal chains 31 is used for hanging the outer jacket bag
30. The tying cords 31 are used for closing the opening of the
outer jacket bag 30.
[0023] Referring to FIG. 5A in company with FIG. 2 again, the first
inner bag 10 is composed of a plurality of chambers 12 and each of
the chambers 12 is injected with gas via a gas hole 121 till being
fully expanded. Alternatively, each of the chambers 12 provides an
opening at the top thereof for filling foam sealing agent or tiny
polystyrene foam balls to expand as a bag with increased hardness.
In case of the foam sealing agent being used, less air chambers are
needed as shown in FIGS. 1A, 2A and 5C. Further, a soft rubber pad
13 is placed at the bottom of the first inner bag 10 for supporting
the weight of the second inner bag 20.
[0024] Referring to FIG. 4 in company with FIG. 3, the second inner
bag 20 has an inlet at the upper end thereof for receiving stuffing
and daughter bags 23 and a cap knob 22 is joined to the inlet by
way of supersonic welding. The lower end of the second bag 20 is
joined with a discharge hole 21 by way of the supersonic welding
for discharging the stuffing and regulating weight thereof and
another cap knob is provided at the discharge hole 21. In order to
facilitate operation for opening and closing of the cap, a recess
type handle 221 is provided at the cap as shown in FIGS. 4 and
5.
[0025] Referring to FIGS. 5, 5A and 5B, when the adjustable type
punching bag of the present invention is in use, gas is injected
into the chamber 12 in the first inner bag 10 via the gas hole 121
as shown in FIG. 5A to fully expand the first inner bag 10 and the
first inner bag 10 is received in the outer bag 30. The soft rubber
pad 13 is disposed between the first inner bag 10 and the second
inner bag 20 as shown in FIG. 5B to bear the weight of the second
inner bag 20. Further, the soft rubber pad 13 has a central hole
131 for being closed by the cap knob 21 such that the liquid in the
second inner bag 20 can be released via the central hole 131. Then,
the second inner bag 20 is received in the first inner bag 10 and
water L is poured into the second bag 20 to increase the overall
weight of the punching bag. If the second inner bag 20 is unable to
fill up the preset weight of water, a plurality of daughter bags 23
are filled with gas and placed in the second inner bag 20 to allow
the water L in the second inner bag 20 distributing evenly without
forming the upper space of the second inner bag 20 being soft
caused by lacking the water L. Besides, the daughter bags 23 can be
stuffed with higher density material to increase the weight of the
punching bag such that the weight of the punching bag is capable of
being under control.
[0026] It is appreciated that the adjustable punching bag of the
present invention is to change the weight of the whole punching bag
by means of changing quantity and kind of the stuffing in the inner
bags and there is no restriction to limit the quantity and the kind
of the used stuffing and it can be mixed based on the need of the
user. Further, the cap knob 21 at the bottom of the second inner
bag 20 is opened first to discharge the water L in the inner bag 20
after the punching bag has been done completely. Then, the cap knob
22 is opened and the daughter bags 23 are taken out with the gas in
the daughter bags 23 being released. Thus, all the bags are folded
and placed in a box B for storage and being carried with the user.
In case of the soft bags being used, the box B can be reduced in
size for being stored, packed and delivered more conveniently.
[0027] While the invention has been described with referencing to a
preferred embodiment thereof, it is to be understood that
modifications or variations may be easily made without departing
from the spirit of this invention, which is defined by the appended
claims.
