First Claim
1. A counterweight exercise machine having a frame capable of standing on a floor steadily;
- the frame comprising;
two main guide rods;
two sub-guide rods;
a passive rod parallel to the two main guide rods;
at least one main weight having a predetermined weight;
the main weight being installed to the two main guide rods;
a selector capable of being inserted into two adjacent main weights and to be engaged to the passive rod;
a base having a lower substrate and an upper substrate; and
two sleeves connected to the lower substrate and the upper substrate;
the two sleeves enclosing the two main guide rods;
the base being engaged to the passive rod to be as an integral body;
the lower substrate having a front sheet and a rear sheet;
each of the front sheet and rear sheet having at least one round hole;
at least one pin capable of passing through the round holes of the front sheet and the rear sheet and the passive rod;
at least one sub-weight having a weight smaller than that of the main weight;
two opposite sides of the sub-weight having vertically penetrating round holes so as to be engaged to the two sub-guide rods vertically;
a center of the sub-weight having a via hole for receiving one end of the pin;
wherein by above mentioned components, the selector serves to lock a predetermined number of main weights and the pin inserts into the sub-weight so as to increase the total weight;

Abstract
A counterweight exercise machine has a frame. The frame comprises two main guide rods; two sub-guide rods; a passive rod parallel to the two main guide rods; at least one main weight; a selector; a base having a lower substrate and an upper substrate; and two sleeves connected to the lower substrate and the upper substrate; at least one pin capable of passing through the round holes of the front sheet and the rear sheet and the passive rod; and at least one sub-weight. By above mentioned components, the selector serves to lock a predetermined number of main weights and the pin inserts into the sub-weight so as to increase the total weight. A force applied unit serves to drive the passive rod to drive the main weight and the sub-weight to operate along the main guide rods and sub-guide rods to achieve the object of training the muscle.
