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.
