Chest expander handle
Abstract
A chest expander handle includes a gripping portion with a
rubber pad mounted around the gripping portion and a connecting
portion having two arms integrally connected to opposed ends of the
gripping portion, a through hole centrally defined through the
connecting portion, a first side hole defined in the connecting
portion, a first cutout defined in an outer periphery of the
connecting portion to communicate with the first side hole and a
second side hole defined in the connecting portion. Therefore, a
first elastic rope is able to extend into the through hole to be
secured to the connecting portion, and a second elastic rope is
able to be securely received in the first side hole via the first
cutout.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a chest expander handle,
and more particularly to the handle enabling the user to easily and
quickly adjust the tension of the chest expander.
[0003] 2. Description of Related Art
[0004] With reference to FIG. 8, a conventional chest expander
handle (50) has a flat portion (51) for gripping by the user and a
connector (52) defining therethrough a central hole (521). When the
handle (50) is provided for use with the chest expander (not
shown), a free end of the elastic rope (60) is extended into the
central hole (521). After the extension of the central hole (521),
the user ties a knot A to the free end of the elastic rope (60)
such that the elastic rope (60) is fixed to the chest expander
handle (50). Due to various strengths of individuals, when the
tension of the elastic rope is to be changed, the user will have to
untie the knot for replacement of a different elastic rope of a
different dimension. Thus tying and untying a knot to the free end
of the elastic rope are too troublesome for the user, especially
when exercisers are particularly intensively busy people. In order
to overcome the shortcoming of the conventional chest expander
handle, a new chest expander handle is shown in FIG. 9. The body of
the chest expander handle (80) has a centrally defined space (82)
in communication with an opening (81) defined through a side face
of the body, and a cylinder (70) is rotatably received in the
opening (81) of the body of the chest expander handle (80). An
elastic rope (60) is mounted around the outer periphery of the
cylinder (70) and extended out from the body of the chest expander
handle (80). Because when the chest expander handle (80) is used,
the cylinder (70) is driven by the elastic rope (60) to move deeper
into the space (82), the elastic rope (60) is secured in the chest
expander handle (80). Although this kind of chest expander handle
(80) allows the user to quickly adjust it for different elastic
ropes, the structure of the chest expander handle (80) is too
complex and thus the manufacture cost is high.
[0005] To overcome the shortcomings, the present invention tends to
provide an improved chest expander handle to mitigate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
an improved chest expander handle enabling the user to quickly
replace the elastic rope, whereby the expander is suitable for
different users.
[0007] In order to accomplish the aforementioned objective, the
chest expander handle of the present invention includes a grip
portion and a connecting portion integrally formed with the grip
portion and having a central hole defined in a body of the
connecting portion and two side holes defined close to the central
hole. The body of the connecting portion is further provided with a
first cutout and a second cutout defined in an outer periphery of
the body of the connecting portion to respectively communicate with
the two side holes. Therefore, an elastic rope is easily
attached/detached to the chest expander handle of the present
invention.
[0008] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] With reference to FIG. 1, the chest expander handle in
accordance with the present invention includes a grip portion (10)
and a connecting portion (20).
[0019] The grip portion (10) is a flat portion with a rubber pad
(not numbered) mounted thereon. The connecting portion (20) has two
arms (11) integrally connected to opposed ends of the grip portion
(10). The connecting portion (20) further has a centrally defined
through hole (21), a first side hole (22) and a second side hole
(22') defined close to the through hole (21). Further, a first
cutout (23) is defined in an outer periphery of the connecting
portion (20) to communicate with the first side hole (22) and a
second cutout (23') is also defined in the outer periphery of the
connecting portion (20) to communicate with the second side hole
(22').
[0020] With reference to FIGS. 2 and 3, when the chest expander
handle of the present invention is assembled with an elastic rope
(40), a free end of the elastic rope (40) is extended through the
through hole (21) and then a ball (41) having a dimension larger
than a diameter of the through hole (21) is inserted into the free
end of the elastic rope (40). Finally a hollow plug (42) having a
dimension smaller than that of the ball (41) is securely mounted on
the free end of the elastic rope (40) to secure the ball (41)
inside the elastic rope (40). Thus the elastic rope (40) is
securely connected to the chest expander handle of the present
invention.
[0021] With reference to FIGS. 4 and 5, the user may slide one
elastic rope (40) from the first cutout (23) to be received in the
first side hole (22) and another elastic rope (40) from the second
cutout (23') to be received in the second side hole (22'). Then the
same manner used in FIG. 3 is applied to secure the two elastic
ropes (40) to the chest expander handle of the present invention.
Furthermore, a third elastic rope (40) may be secured to the chest
expander handle via the through hole (21) in the same manner as
described in FIGS. 2 and 3.
[0022] With reference to FIG. 6, it is noted that the user may
extend the free end of the elastic rope (40) over the first side
hole (22) and then bend the free end of the elastic rope (40) for
extension into the second side hole (22') via the second cutout
(23') and thus the elastic rope (40) is secured to the chest
expander handle of the present invention.
[0023] With reference to FIG. 7, it is noted that the chest
expander handle has a third cutout (23'') defined in the outer
periphery of the connecting portion (20') of the chest expander
handle so that the elastic rope (40) is able to be received in the
through hole (21') via the third cutout (23'').
[0024] It is to be understood, however, that even though 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 full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
