Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an exercise device, and
more particularly to a portable stretching exercise device
receivable as a portable case, and for conducting push and pull
type exercises.
[0003] 2. Description of the Prior Art
[0004] Various kinds of typical exercise devices have been
developed for exercising legs or the like. For example, U.S. Pat.
No. 1,750,549 to Thomson et al., U.S. Pat. No. 3,620,530 to Cosby,
U.S. Pat. No. 4,506,884 to Hankin, U.S. Pat. No. 5,147,266 to
Ricard, and U.S. Pat. No. 5,295,935 to Wang disclose five of the
similar typical exercise devices.
[0005] In these typical exercise devices, two supporting members,
such as foot pedals or seats are slidably secured along one or more
tracks, and to be moved along the tracks, such that the tracks and
the supporting members form a huge volume that may not be easily
carried or moved or used by the users.
[0006] In addition, the track members should be made of metal
materials, and thus include a great or heavy weight. Furthermore,
the foot pedals or the seats or the supporting members may not be
superposed with each other, and thus may not be folded or stored to
a compact volume or structure.
[0007] The other typical exercise devices provide a spring-biased
wheel member received in a hand-held housing for exercising the
waist portion of the users. However, the typical exercise devices
also made of metal materials and comprise a heavy weight that also
may not be easily carried with the users.
[0008] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional exercise
devices.
SUMMARY OF THE INVENTION
[0009] The primary objective of the present invention is to provide

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Referring to the drawings, and initially to FIGS. 1-4, an
exercise device in accordance with the present invention comprises
two non-track supporting members 10, 30, such as a stationery
member 10 having one or more pads 11 (FIG. 3) attached to one side,
such as the bottom side thereof, for engaging with the supporting
surface or ground, and for positioning the stationery member 10 on
the supporting ground, and for preventing the stationery member 10
from moving relative to the supporting ground.
[0027] The pads 11 may be made of rubber or plastic or the other
synthetic materials that are not slippery and that may provide a
resistance or anti-frictional force between the pads 11 and the
supporting ground. The pads 11 may be secured onto the stationery
member 10 with adhesive materials, by welding processes, or may be
detachably secured onto the stationery member 10 with such as the
hook-and-loop fastening members.
[0028] The other supporting member 30 is a slippery member 30 and
includes a planar or slippery sheet or layer 31 attached to one
side, such as the bottom side thereof, for engaging with the
supporting surface or ground, and for allowing the slippery member
30 to be moved relative to the supporting ground. For example, the
slippery layer 31 is made of plastic or synthetic materials that
have a slippery outer surface for slipping and moving relative to
the supporting ground, and for allowing the slippery member 30 to
be easily moved relative to the stationery member 10.
[0029] The slippery layer 31 may also be directly secured onto the
slippery member 30 with adhesive materials, by welding processes,
or may be indirectly secured onto the slippery member 30 via a
cushioning or spongy sheet 32. The provision or the attachment of
the cushioning sheet 32 between the slipper member 30 and the
slippery layer 31 allows the slippery layer 31 to be slightly
deformed when the slipper layer 31 and the slippery member 30 are
moved over uneven or bouncy ground or supporting surface.
[0030] A resilient or spring biasing member 20 is further provided
and coupled between the stationery member 10 and the slippery
member 30. The stationery member 10 and the slippery member 30 may
each include a channel or groove 14, 34 formed therein for
receiving the spring biasing member 20, and for allowing the spring
biasing member 20 to be resiliently coupled between the stationery
member 10 and the slippery member 30, and thus for biasing or
moving the slippery member 30 backward or toward the stationery
member 10.
[0031] For example, as shown in FIG. 5, the stationery member 10
and the slippery member 30 each includes a semi-circular or
semi-elliptical groove 14, 34 formed therein, and the spring
biasing member 20 includes an endless structure or a loop shape and
having two ends secured together, or having two separate portions
received in the grooves 14, 34 of the stationery member 10 and the
slippery member 30 respectively, and for allowing the spring
biasing member 20 to be solidly and stably received and coupled
between the stationery member 10 and the slippery member 30.
[0032] As also shown in FIG. 5, it is preferable that the
stationery member 10 and the slippery member 30 are made of spongy,
rubber, foamable, or synthetic materials, and each includes two
half-elements 13, 33 each having the grooves 14, 34 formed therein
for receiving the spring biasing member 20. The half-elements 13,
33 may be secured together by such as the adhesive materials, or by
welding processes, or by hot-pressing processes.
[0033] For example, the half-elements 13, 33 may be secured
together after the spring biasing member 20 has been engaged into
the grooves 14, 34 of the half-elements 13, 33; or may be secured
together first, and threading or engaging the spring biasing member
20 through the grooves 14, 34 of the half members 13, 33 of the
stationery member 10 and the slippery member 30. The spring biasing
member 20 may include two ends secured together after the spring
biasing member 20 has been threaded or engaged through the grooves
14, 34 of the half members 13, 33 of the stationery member 10.
[0034] In operation, as shown in FIGS. 9-12, the stationery member
10 may be stably supported and positioned on the supporting ground
with the anti-slippery pads 11. The users may have the knees (FIG.
9), the buttocks (FIG. 10), the feet (FIG. 11), or one of their
knees (FIG. 12) disposed or seated or supported on the stationery
member 10, and may have the hands (FIGS. 9, 11), the feet (FIG.
10), or the other feet (FIG. 12) supported on the slippery member
30, for moving the slippery member 30 toward and away from the
stationery member 10 against the spring biasing member 20, and for
conducting push and pull type exercises.
[0035] Alternatively, as shown in FIG. 6, the spring biasing member
20 may include two ends 22 secured together by a rod 21 or two rods
21 (FIG. 7), or the like. As shown in FIG. 8, the spring biasing
member 20 may include two ends secured to two rods 21 respectively
that are received or secured or retained in the stationery member
10 and the slippery member 30 respectively.
[0036] Referring again to FIGS. 1 and 2, the stationery member 10
and the slippery member 30 are not supported on tracks, and may be
superposed with each other to form a compact case structure. The
spring biasing member 20 may be formed as a coupling member between
the stationery member 10 and the slippery member 30, for coupling
the stationery member 10 and the slippery member 30 together, and
for allowing the stationery member 10 and the slippery member 30 to
be easily carried with the spring biasing or coupling member
20.
[0037] The stationery member 10 and the slippery member 30 may each
further provide a fastening member or locking member or latching
member or securing member 16, 36 attached thereto, such as the
hook-and-loop securing members 16, 36 attached thereto, for
engaging with each other, and for openably securing the stationery
member 10 and the slippery member 30 together, or for maintaining
or retaining the stationery member 10 and the slippery member 30 at
the superposed case structure as shown in FIGS. 1 and 2.
[0038] As shown in FIG. 3, it is preferable that the pads 11 are
arranged on the peripheral portion of the stationery member 10, for
forming or defining a space 12 within the pads 11, and for
receiving the slippery layer 31 and/or the cushioning sheet 32 of
the slippery member 30. The exercise device is good for mass
production.
[0039] Accordingly, the exercise device in accordance with the
present invention includes two non-track supporting members that
may be superposed with each other to form a compact case structure
and that may be easily carried or moved by the users, and that may
be easily moved and supported in any planar surface at any places,
and that may be easily manufactured with a mass-production
process.
[0040] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
