In one embodiment, a head end of first baseboard member 301 is detachably coupled to a lower end of sidebar 113, for example, via a first locking mechanism disposed at the head end of baseboard member 301. A head end of second baseboard member 302 is detachably coupled to a lower end of sidebar 114, for example, via a second locking mechanism disposed at the head end of baseboard member 302.

In one embodiment, the first locking mechanism includes a first lock member disposed on the head end of baseboard member 301 (not shown), which can be inserted into a cross section (e.g., an opening or tubular shape) of the lower end of side pole 113, when pole frame 101 is positioned substantially perpendicular to base frame 102 to interlock with base frame 102. When pole frame 101 and base frame 102 are interlocked, a locking hole disposed at the lower end of sidebar 113 and a locking hole disposed at the head end of baseboard member 301 are aligned to allow locking pin 151 to be inserted across the locking holes to prevent pole frame 101 from being detached from base frame 102. Similarly, the locking mechanism associated with side pole 114 and baseboard member 302 is similar using locking pin 152, as shown in FIG. 2. FIG. 4B shows an explosive view of the exercise device according to one embodiment of the invention.

Referring now to FIG. 2, for the purpose of illustration, FIG. 2 shows an enlarged version of a locking mechanism disposed between base pole 122 of sidebar 113 and head section 311 of baseboard member 301. The description is equally applicable to another locking mechanism disposed between base pole 124 of sidebar 114 and head section 312 of baseboard member 302. In one embodiment, locking member 351 is mounted on the head end of head section 311 of baseboard member 301. In this example, locking member 351 is in a U-shape form that is suitable to be inserted into a cross section of base pole 122. Locking member 351 includes locking hole 353, while base pole 122 includes a corresponding locking hole 352. When base pole 122 is lowered to allow locking member 351 to be inserted into its cross section, locking holes 352-353 are aligned to allow locking pin 151 to be inserted across through the aligned locking holes 352-353 for interlocking. In order for pole frame 101 to be detached from base frame 102, locking pin 151 has to be pulled from locking holes 352-353. Further, a first knob or tight control member 185 is disposed at the lower end of pole 122, which can be used to tighten pole 122 against locking member 351. Similarly, a second knob or tight control member 186 is disposed at the lower end of pole 124 for the similar purpose. The length of locking member 351 is determined such that it is long and steady enough to hold pole frame 101 substantially perpendicular to base frame 102 in an interlocked position.

Referring now to FIG. 3, as described above, first baseboard member 301 includes head section 311 and rear section 313, while second baseboard member 302 includes head section 312 and rear section 314. In one embodiment, head section 311 and rear section 313 are coupled to each other via a hinge (e.g., a vertical hinge) to allow rear section 313 to swing or tilt outwardly with respect to head section 311. Such a configuration allows rear section 313 to swing up to 180 degrees to be in a position side by side with head section 311. As a result the exercise device can be disassembled without having to take apart head section 311 and rear section 313. Head section 312 and rear section 314 have the same or similar structure as shown in FIG. 3.

In the foregoing specification, embodiments of the invention have been described with reference to specific exemplary embodiments thereof. It will be evident that various modifications may be made thereto without departing from the broader spirit and scope of the invention as set forth in the following claims.
