Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a multi-purpose exercise
device with synchronized sliding, and more particularly to an
exercise device with two slides freely slidable along the same
tracks from one end to the other. Furthermore, the two slides are
connected by elastic bands and each of the slides includes three
poles arranged in the shape of a triangle. The elastic bands are
engaged over at least two poles of each slide, providing more
flexible and interesting sliding exercises.
[0003] 2. Description of the Prior Art
[0004] A typical exercise device is disclosed in U.S. Pat. No.
1,750,549 to Thomson et al., and includes a seat slidable along a
track section. The device is not suitable for practicing leg
stretching.
[0005] Another typical exercise device is disclosed in U.S. Pat.
No. 3,620,530 to Cosby and includes a carriage slidable along a
supporting frame. The device is not suitable for practicing body
stretching. Furthermore, an additional chair is required for
practicing muscle groups of the legs.
[0006] Still another typical exercise device is disclosed in U.K.
Pat. No. 2,120,110 to Torii and includes a pair of foot boards
movable away from each other against the springs. However, the
moving distance of the foot boards is limited by the springs such
that the legs of the user can not be fully stretched.
[0007] One more exercise device, the antecedent of the present
invention, is disclosed in U.S. Pat. No. 5,295,935 to Wang. It
includes a pair of slides engaged on tracks and oppositely disposed
beside a seat. The device has the following two disadvantages:
[0008] 1. Sliding modes are very limited such that little variety
of exercises are provided, due to each of the slides being moved
along the tracks on just one side of the seat.
[0009] 2. The device is of high cost and hard to assemble or
maintain, due to its multiple members with each of the slides being
coupled to a spring and a plurality of elastic bands.
[0010] Moreover, on the market there may be an exercise device
including two slides engaged on tracks and connected by elastic
bands. The elastic bands of such a conventional exercise device
have each end directly fixed to each of the slides without being
specially extended for engagement. Thus in operating the
conventional exercise device, the two slides could not be joined
together due to the elastic bands in between. Furthermore, in the
conventional exercise device, to prevent the elastic bands from
being too long so as to become an obstruction, they are designed to
be very short such that the stretching distance is limited and
consequently the user could not practice major stretching movements
(such as the legs being fully stretched).
SUMMARY OF THE INVENTION
[0011] The primary objective of the present invention is to provide
an exercise device comprising two slides freely slidable along the
same tracks from one end to the other. Furthermore, the two slides
are connected by elastic bands and each of the slides includes
three poles arranged in the shape of a triangle. The elastic bands
are engaged over at least two poles of each slide, providing more
flexible and interesting sliding exercises.
[0012] In accordance with one aspect of the invention, an exercise
device is provided comprising a base and two slides engaged on the
same tracks. The two slides are connected by elastic bands and each
of the slides includes three poles arranged in the shape of a
triangle. The elastic bands are engaged over at least two poles of
each slide. The two slides are coupled to rollers engaged in the
grooves of the tracks such that the two slides can simultaneously
be moved from one end of the tracks to the other.
[0013] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed
description provided herein below, with appropriate reference to
the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Referring to the drawings, and initially to FIGS. 1 to 5, an
exercise device in accordance with the present invention comprises
a base 11 and tracks 10 disposed on the base 11. The tracks 10
includes a groove 12 and two slides 20a{grave over ()}20b are
engaged on the tracks 10. The two slides 20a{grave over ()}20b are
connected by elastic bands 34 and each of the slides 20a{grave over
()}20b includes three poles 33a{grave over ()}33b arranged in the
shape of a triangle, and at least two of said poles are pivotally
mounted on pulley 35a{grave over ()}35b. The elastic bands 34 are
engaged over the pulleys 35a{grave over ()}35b of the poles
33a{grave over ()}33b of each slide 20a{grave over ()}20b. The two
slides 20a{grave over ()}20b each includes rollers 21. The rollers
21 of the slides 20a{grave over ()}20b are engaged in the grooves
12 of the tracks 10. The user can manipulate the two slides
20a{grave over ()}20b more flexibly and slide freely on the tracks
10 such that better exercise functions are formed.
[0027] As best shown in FIG. 1, in coupling the invention, a pair
of parallel tracks 10 can be disposed on a base 11. Each track 10
includes a groove 12 and the slides 20a{grave over ()}20b each
includes two rollers 21 on both sides. The rollers 21 on each side
of the slides 20a{grave over ()}20b are engaged in the groove 12 of
a track 10.
[0028] As best shown in FIG. 9, in coupling the invention, the
resilient members include two elastic bands 30a{grave over ()}30b.
Each elastic band 30a{grave over ()}30b are fixed to a hooking ring
31a{grave over ()}31b at both ends. Two poles 33a{grave over ()}33b
of each slide 20a{grave over ()}20b are coupled to pulleys
32a{grave over ()}32b. The hooking ring 31a{grave over ()}31b at
both ends of each elastic band 30a{grave over ()}30b is engaged on
the poles 33a{grave over ()}33b of a slide 20a{grave over ()}20b.
Each elastic band 30a{grave over ()}30b is engaged over one pulley
32a{grave over ()}32b of each slide 20a{grave over ()}20b such that
the two elastic bands 30a{grave over ()}30b provide synchronized
resilience between the two slides 20a{grave over ()}20b.
[0029] As shown in FIG. 3, in coupling the invention, the resilient
members constitute a closed circuit of circular elastic bands 34.
Each of the three poles 33a{grave over ()}33b of each slide
20a{grave over ()}20b include a pulley 35a{grave over ()}35b such
that the elastic bands 34 are engaged over every pulley 35a{grave
over ()}35b of the two slides 20a{grave over ()}20b.
[0030] As shown in FIG. 12, in coupling the invention, the base 11
can be fixed to a handle bar 110. The top of the handle bar 110
includes a handle grip 111 parallel to the tracks 10. The handle
grip 111 allows the user to practice major exercise movements
stably.
[0031] As shown in FIG. 1, in coupling the invention, an elastic
rope 14a{grave over ()}14b can be attached to each end of the
tracks 10. The user can pull the ends of the elastic ropes
14a{grave over ()}14b, with one end in each hand, and slide to the
left or to the right.
[0032] As shown in FIGS. 1 and 4, in coupling the invention, each
slide 20a{grave over ()}20b can include a stop 22 at its end such
that the user's feet can press against it and stand stably on the
slides 20a{grave over ()}20b. The stop can include two brackets 220
and a handle grip 222 pivotally engaged in the holes 221 of the
brackets 220. The handle grip 222 not only serves as a foot stop
but also allows the user to practice muscle groups of arms and
abdomen.
[0033] As shown in FIGS. 7 and 8, in coupling the invention, the
tracks 10 can include holes 100 in which pins 13 are engaged. The
pins 13 stop a slide 20a{grave over ()}20b such that it is in a
state of being fixed on the tracks, while the other slide 20a{grave
over ()}20b can freely slide on the tracks 10, suitable for
practicing of the abdominal muscles.
[0034] Based on the technique and theory of the invention, the two
slides 20a{grave over ()}20b can simultaneously and freely be moved
on the tracks 10. Both of the slides 20a{grave over ()}20b may be
moved from one end of the tracks 10 to the other. The sliding area
is extended, allowing more variety of exercise movements.
Furthermore, the two slides 20a{grave over ()}20b are coupled to
resilient members, providing synchronized resilience between the
slides 20a{grave over ()}20b. Better exercise effects can be
achieved with the assistance of various exercise movements.
[0035] Referring next to FIGS. 10 and 11, in operations, the user
can have each foot step on a slide 20a{grave over ()}20b and the
legs be fully stretched laterally or frontally, with the front of
the body being parallel to the tracks 10 and the legs being fully
stretched frontally; another way is to move the two slides
20a{grave over ()}20b from one end of the tracks 10 to the other as
in sliding on a skating board. In operations, the two slides
20a{grave over ()}20b are moved either toward or away from each
other. Due to the resilient members between the two slides
20a{grave over ()}20b, the user can slide rhythmically, practicing
better exercise functions and adding more fun.
[0036] Referring next to FIGS. 7 and 8, in operations, pins 13 can
be engaged on the tracks 10 to stop a slide 20a{grave over ()}20b
such that it is in a fixed state. The users can kneel on a slide
20a or 20b and hold the handle grip 222 of the other slide 20b or
20a such that the body can be stretched to practice muscle groups
of the abdomen.
[0037] Besides, in operations, the hands can respectively hold the
handle grip 222 of a slide 20a{grave over ()}20b. Then the hands
can swing toward or away from each other to practice muscle groups
of the chest and arms.
[0038] Thus the two slides of the invention include three poles
arranged in the shape of a triangle. The elastic bands engaged over
the three poles are extended in length, increasing their stretching
modes and allowing the user to practice major exercise movements
more flexibly.
