Power expanderPower expander description/claimsThe Patent Description & Claims data below is from USPTO Patent Application 20090253562, Power expander. Brief Patent Description - Full Patent Description - Patent Application Claims
1. Field of the Invention The present invention relates to a power expander, and more particularly to a power expander that can accurately count the times of breast expanding in order to get an object of gradually training. 2. Description of the Prior Art Sustained training with weights not only can help users to build up muscle power to make muscles strong, but also can increase power of bodies, get better form of the muscles, and avoid problems in physical functions resulted from fat bodies. Using a power expander can get evident effects in basic physical trainings on the muscles of shoulders, backs and for breast expanding. A conventional power expander mainly includes a plurality of elongate elastic members and two elongate pipe-like handles, two ends of each elastic member connects with a handle, in order that when a user can exert forces on the handles to overcome the pulling back force of the elastic members, the elastic members are elongated for the purpose of muscle training and increasing power of muscles. However, when in muscle training, a user often stretches the elastic members quickly or concentrates on exerting force for exercise and thereby can not care for counting the times of expanding. And thereby he generally is unable to get a standard for comparison in training and for accurately controlling for achieving the object of exercise gradually in a sequence. In view of this, and in order to get rid of the above defects and to not only make the power expander capable of counting the times of spreading to get the effect of muscle training and plastic modeling, but also capable of counting accurately to get a standard for comparison in training and for achieving the object of exercise gradually in a sequence. The inventor thus provided the present invention based on his professional experience of years in studying, developing and improving over the conventional training equipments. The primary object of the present invention is to provide a power expander capable of counting the times of spreading, in which by providing a structure having a counting member on a slide seat able to move relatively and on the slide seat on a first handle and having an actuating member on the first handle, when a user stretches the elastic members to pull and move the slide seat, the actuating member can press the counting member to do counting to build up a standard for comparison in training. For achieving the above object, the power expander capable of counting times of the present invention comprises a slide seat, a plurality of elastic members and a counting member. Wherein the slide seat is connected to the first handle to be movable relatively within a limited range, the first handle has an actuating member; one end of each of the elastic members is connected to a second handle, the other end is connected to the slide seat; the counting member is connected to the slide seat to contact the actuating member. When in practicing, the slide seat is provided with a through hole in order that the actuating member of the first handle presses the counting member after extending through of the actuating member. And when in practicing, the counting member includes a counter, an engaging member and an upper lid; the counter is connected to the top of the slide seat, and is provided with a push button; the engaging member is pivotally connected to the upper lid, one end of the engaging member contacts the actuating member, the other end is kept a predetermined distance from the push button, in order when the elastic members and the slide seat are pulled, the actuating member abuts against the engaging member, thus the engaging member rotates to press the push button to do counting. And when in practicing, one end of the slide seat is provided with a plurality of positioning grooves for respectively positioning the elastic members; one end of each elastic member is abutted against the inner side on an end of the first handle. Two lateral sides of the slide seat are provided each with a first rail which has a limiting portion, while two lateral sides of the first handle are provided each with a second rail which has a guiding portion; the first and the second rails on each of the lateral sides cooperate with each other, and the guiding portions and the limiting portions on each of the lateral sides cooperate with each other too, so that the slide seat can slide relatively to the first handle. The present invention will be more apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
