Patent ID: 6860836

Claim:
A rock climbing exerciser comprising: a main frame including a base member adapted to abut against a supporting surface and two stands perpendicularly extending from the base member, each stand having a C-shaped cross-section and a channel longitudinally defined therein, the two channels of the two stands facing each other; a cyclic device mounted between the two stands, the cyclic device includes a first drive device laterally mounted to a lower portion of each of the two stands and a second drive device laterally mounted to an upper section of the two stands, the first drive device including a first shaft having two opposite ends respectively pivotally connected to a corresponding one of the two stands and multiple first chain wheels securely mounted to the first shaft and spaced in equal intervals, the second drive device including a second shaft having two opposite ends respectively pivotally connected to a corresponding one of the two stands and multiple second chain wheels securely mounted to the second shaft and spaced in equal intervals, wherein the number of the first chain wheels is the same as the second chain wheels and each chain wheel aligns with a corresponding one of the second wheels, a chain endlessly encircled the first chain wheel and the second chain wheel that align with each other so that the multiple first chain wheels and the multiple second chain wheels are synchronously operated, each chain including multiple ears outwardly extending therefrom at equal intervals, each ear of each of the chains horizontally corresponding to that of the adjacent chain, a lateral panels mounted on the ears that horizontally correspond to one another on the chains, each lateral panel having two opposite ends respectively extending into the channels of the two stands, an endless strap mounted around and secured on the lateral panels for covering the first drive device and the second drive device, multiple grips extending through the endless strap and detachably mounted to the lateral panels for user to hold and climb on the endless strap, multiple U-shaped brackets mounted between the two stands for receiving the chains to prevent the lateral panels and the chains from being inward moved during operating; and a speed reducer connected to the cyclic device for reducing the moving speed of the endless strap for user to climb on the endless strap.
