Abstract
A grip structure is designed for use in an exercise device and is formed of a main body, a grip rod, and two slide blocks disposed at two ends of the grip rod. The main body is of a ring-shaped construction and is provided with a groove. The main body is fastened with a predetermined portion of the operation rod of the exercise device. The slide blocks are slidably received in the groove of the main body. The grip rod can be adjusted 360 degrees in relation to the main body, thereby enabling a change in direction in which the grip rod is held fast by an exerciser.
Description
FIELD OF THE INVENTION
The present invention relates generally to an exercise device, and more particularly to a grip structure of the exercise device.
BACKGROUND OF THE INVENTION
There are a variety of exercise devices calling for the use of both hands of an exerciser for building the body muscles. The grip portion is intended to be held by hand of the exerciser and is generally fixed at a position of the handle such that the grip portion can not be adjusted in position to facilitate the training of the upper half body of the exerciser. As a result, the exerciser must resort to an improper posture which works against the mechanics of the human body. This inventor of the present invention discloses a grip structure comprising a grip portion changeable in direction in which the grip portion is disposed. The grip portion is adapted to be held in various ways for building the muscles of various parts of an exerciser's body. However, this grip structure is complicated in construction and is not cost-effective.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an exercise device with a grip structure which is simple in construction and is provided with a grip portion which can be changed in direction in which a force is exerted for the purpose of building muscles of various parts of a human body.
The present invention comprises a main body and a grip member. The main body is disposed in a predetermined portion of an operation rod of an exercise device and is of a ring-shaped construction. The main body has an outer ring portion, an inner ring portion, and a groove extending along the inner ring portion. The grip member comprises a grip rod and two slide blocks which are disposed at two ends of the grip rod. The grip rod is intended for holding fast with hand. The slide blocks move along the groove. The grip rod can be adjusted in the range of 360 degrees in the main body, thereby resulting in a change in direction in which the grip rod is held fast.

DETAILED DESCRIPTION OF THE INVENTION
As shown in
FIGS. 1-4
, a grip structure
20
embodied in the present invention is disposed on an application portion of operation rod of an exercise device and is formed of a main body
30
and a grip member
40
.
The main body
30
is of a ring-shaped construction having a predetermined diameter. The main body
30
has an outer ring portion
31
and an inner ring portion
32
. A groove
33
of a predetermined depth is disposed along the inner ring portion
32
such that the groove
33
is in communication with a through hole
34
extending from the outer ring portion
31
through the inner ring portion
32
.
The grip member
40
comprises a grip rod
41
and two slide blocks
42
and
43
, which are disposed at two ends of the grip rod
41
.
The grip rod
41
is of a columnar construction and has two ends smaller in diameter and having respectively an inner threaded hole
411
,
412
.
The slide blocks
42
and
43
are of an inverted T-shaped construction and are provided respectively with a circular stop portion
421
,
431
, and a slide portion
422
,
432
. The circular stop portions
421
and
431
are circular disk bodies with a diameter greater than the width of the groove
33
of the main body
30
and corresponding in radian to the inner ring portion
32
. The circular stop portion
421
,
431
is provided in the bottom with an inner recess hole
423
,
433
with a diameter corresponding to the diameter of the end of the grip rod
41
for connecting the grip rod
41
.
The slide portion
422
,
432
is a round columnar body extending from the center of the circular stop portion
421
,
431
and having a diameter corresponding to the width of the groove
33
of the main body
30
for inserting slidably into the groove
33
. The slide blocks
42
and
43
are provided at the center with a threaded hole
424
,
434
corresponding to the inner threaded hole
411
,
412
for engaging two bolt elements
44
and
45
to connect the slide blocks
42
and
43
with the grip rod
41
. The bolt elements
44
and
45
are preferably sunken screws. The threaded holes
424
and
434
are preferably sunk holes to prevent the bolt elements
44
and
45
from jutting out of the slide portions
42
and
43
to affect the sliding of the slide portions
42
and
43
.
As shown in
FIGS. 3 and 4
, two ends of the grip rod
41
are first inserted into the inner recess holes
423
and
433
of the slide blocks
42
and
43
such that the slide portions
422
and
432
of the slide blocks
42
and
43
are inserted into the groove
33
of the main body
30
, and that the circular stop portions
421
and
431
of the slide blocks
42
and
43
are stopped on the groove
33
and are attached to the inner ring portion
32
of the main body
30
. The inner threaded hole
424
of the slide block
42
is aligned with the through hole
34
of the main body
30
. A bolt element
44
is inserted into the through hole
34
to engage the threaded hole
424
of the slide block
42
and the inner threaded hole
411
of the grip rod
41
. Thereafter, the grip rod
41
is turned such that the inner threaded hole
434
of the slide block
43
is aligned with the through hole
34
of the main body
30
. Similarly, a bolt element
45
is put into the through hole
34
to complete the fastening of the grip rod
41
.
The grip structure
20
of the present invention is applicable to a variety of exercise devices, as shown in FIG.
5
. The grip structure
20
is disposed on a multifunctional exercise device
50
such that the main body
30
is fastened with the ends of two operation rods
511
and
512
of the push-lift mechanism
51
, and that the through hole
34
of the main body
30
is located under or in the inner side of the main body
30
for receiving the bolt elements
44
and
45
. The grip member
40
located in the groove
33
of the main body
30
can be rotated for an angle of 360 degrees in relation to the main body
30
. As a result, the grip rod
41
can be so rotated that the grip rod
41
is perpendicular to the longitudinal direction of the operation rod
51
, and that the grip rod
41
is in a horizontal state. The user may hold horizontally the grip rod
41
such that palms of both hands face outwards, and that both fists are opposite to each other, thereby enabling the user to push the operation rods
511
and
512
up and down. In addition, the grip rod
41
may be so rotated that the grip rod
41
is in a vertical state, thereby enabling the user to push the operation rods
511
and
512
up and down, with palms of both hands of the user being opposite to each other, and with fists facing rearwards. As a result, muscles of various parts of the user's body are trained.
As shown in
FIG. 6
, the grip structure
20
of the present invention is disposed on a butterfly machine
60
such that the main body
30
is fastened with two opposite inner sides of two operation rods
61
and
62
. The grip member
40
is adjusted 360 degrees in relation to the main body
30
, so as to enable the user to change the direction in which the grip rod
41
is held fast. The user can choose a desired manner to grip the grip rod
41
to engage in an exercise. The exercise machine can be used in various manners to train the muscles of various parts of the user's body.
