Multi-functional exercise device

Abstract

A multi-functional exercise device includes an upper part and a lower part. The upper part has a base. The base includes two side walls extending from two sides thereof, a grip member mounted between the two side walls, and an elastic engaging hook beneath the base. The lower part includes a support disc having a central engaging hole for the elastic engaging hook to be engaged therein, at least one mounting portion at a lower end of the support disc, and at least one rolling element mounted to the mounting portion. The elastic engaging hook of the upper part is engaged with the engaging hole of the lower part so that the upper part and the lower part are connected together. The upper part is applied with a force to drive the lower part to move along the direction of the applied force for the user to do exercises.

What is claimed is: 
     
         1 . A multi-functional exercise device, comprising:
 an upper part, the upper part having a base, the base including two side walls extending from two sides thereof, a grip member mounted between the two side walls, and an elastic engaging hook beneath the base;   a lower part, the lower part including a support disc having a central engaging hole for the elastic engaging hook to be engaged therein, at least one mounting portion at a lower end of the support disc, and at least one rolling element mounted to the mounting portion; the elastic engaging hook of the upper part being engaged with the engaging hole of the lower part so that the upper part and the lower part are connected together.   
     
     
         2 . The multi-functional exercise device as claimed in  claim 1 , wherein the elastic engaging hook serves as the center of a circle, a periphery of the elastic engaging hook is provided with engaging tenons which are radially arranged; and the support disc of the lower part is provided with a plurality of connecting grooves corresponding to the engaging tenons. 
     
     
         3 . The multi-functional exercise device as claimed in  claim 1 , wherein the rolling element is in the form of a roller, a middle of the rolling element has a reduced portion, the mounting portion further includes a braking device, the braking device includes an eccentric operating plate and a connecting shaft, the connecting shaft is disposed in a radial direction relative to the rolling element, the eccentric operating plate includes an operating edge and a contact portion, the contact portion is configured to block the reduced portion, and the operating edge is used for the user to operate the braking device to brake the rolling element. 
     
     
         4 . The multi-functional exercise device as claimed in  claim 3 , wherein the eccentric operating plate is one of an eccentric protruding block and an eccentric engaging detent. 
     
     
         5 . The multi-functional exercise device as claimed in  claim 1 , wherein an outer edge of the elastic engaging hook is sleeved with a compression spring, when the user exerts a force toward the lower part through the grip member, the upper part is displaced toward the lower part, when the user releases the grip member, without exerting a force, the compression spring rebounds and brings the upper part back to its original position. 
     
     
         6 . The multi-functional exercise device as claimed in  claim 1 , wherein the elastic engaging hook is replaced by a protruding cylinder, the cylinder has an inner threaded portion, the cylinder is mounted in the engaging hole of the lower part, the upper part is coupled to the lower part through a screw and a washer, when in use, the user holds the grip member to pivot the upper part relative to the lower part. 
     
     
         7 . A multi-functional exercise device, comprising:
 an upper part, the upper part having a base, the base including a soft pad thereon and an elastic engaging hook beneath the base;   a lower part, the lower part including a support disc having a central engaging hole for the elastic engaging hook to be engaged therein, at least one mounting portion at a lower end of the support disc, and at least one rolling element mounted to the mounting portion; the elastic engaging hook of the upper part being engaged with the engaging hole of the lower part so that the upper part and the lower part are connected together.   
     
     
         8 . The multi-functional exercise device as claimed in  claim 7 , a lower end of the upper part is provided with three protruding posts, the lower part is provided with three curved slots corresponding to the posts, the lower part is mounted under the upper part through the elastic engaging hook, and the upper part is rotatable relative to the lower part. 
     
     
         9 . The multi-functional exercise device as claimed in  claim 7 , wherein a surface of the lower part is provided with at least one Velcro® strip. 
     
     
         10 . The multi-functional exercise device as claimed in  claim 7 , wherein a lower end of the upper part is provided with a plurality of non-skid protrusions.
