DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

(9) With reference to FIGS. 1 to 4, an exercise pad in accordance with the present invention comprises a base 10 and a pad body 20. The base 10 is annular and is composed of multiple base units 12. Preferably, the base 10 is composed of four base units 12. Each base unit 12 is curved and has a concave top surface 122, a bottom surface, an inner edge, two ends, a curved recess 128, and at least one positioning post 125. The ends of each base unit are provided respectively with at least one connection recess 124 and at least one connection post 126. The at least one connection post 126 of each base unit 12 is inserted respectively into the at least one connection recess 124 in the adjacent base unit 12. Accordingly, the base units 12 are combined with each other to form the annular base 10. The curved recess 128 is defined in the bottom surface and extends to the inner edge of the base unit 12, and the curved recesses 128 of the multiple base units 12 form an annular recess in a bottom of the base 10. The at least one positioning post 125 is formed on and protrudes from the bottom surface of the base unit 12. In the first embodiment, the at least one positioning post 125 is formed on an inner surface of the curved recess 128 in the base unit 12.

(10) The pad body 20 is inflatable, is combined with the base 10, and has a convex bottom 22, an annular connection flange 24, and multiple positioning holes 242. Preferably, a nozzle is mounted on the pad body 20 for a user to inflate the pad body 20. In the first embodiment, the pad body 20 may be semispherical or spherical in shape. The convex bottom 22 is complementary in shape with the concave top surfaces 122 of the base units 12. The annular connection flange 24 is formed around a bottom edge of the convex bottom 22 and extends into and is held in the annular recess in the base 10. With the annular connection flange 24 extending into the annular recess in the bottom of the base 10, the pad body 20 can be securely held in and combined with the base 10. The positioning holes 242 are defined through the connection flange 24. The at least one positioning post 125 on each base unit 12 extends respectively into at least one of the multiple positioning holes 242 in the pad body 20. With the positioning posts 125 extending into the positioning holes 242, the combination between the pad body 20 and the base 10 is enhanced.

(11) With such an arrangement, a user can sit on the pad body 20 to stretch or expand his/her body for exercising. Because the base 10 is composed of multiple base units 12, the base 10 can be disassembled into multiple base units 12 for packaging or transport. At this time, the pad body 20 can be inherently detached from the base 10. Therefore, the space for transporting or storing the exercise pad can be effectively reduced. In addition, to detach or to combine the base 10 with the pad body 20 does not need any tool and can be done manually by a user, so the exercise pad is convenient in use.

(12) With reference to FIG. 5, in the second embodiment, the at least one positioning post 125A in each base unit 12A is implemented as one in amount and is formed on and extends from one of the at least one connection post 126A on the base unit 12A. Accordingly, the structure of the base unit 12A can be simplified, and the manufacturing cost for the exercise pad can be reduced.

(13) With reference to FIG. 6, in the third embodiment, the pad body 20B has a concave top and multiple protuberances 26 formed on and protruding from the concave top. Therefore, the user can sit in the concave top of the pad body 20B, and the protuberances 26 can provide a massaging effect to the user.

(14) With reference to FIG. 7, in the fourth embodiment, the base 10C further has two resilient ropes 11 connected with the base 10C and being diametrically opposite each other. Accordingly, while the user sits on the pad body 20, the user can pull and extend the resilient ropes 11 with two hands for difference exercises, such that the exercise pad in accordance with the present invention is versatile in use.

(15) 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.
