Description:

FIELD OF THE INVENTION

[0001] The present invention relates generally to an exercise machine, and more particularly to a press device of an exercise machine.

BACKGROUND OF THE INVENTION

[0002] While the material life of modern people is getting better and better, they care about their health more and more and then exercising in gymnasiums at their leisure becomes a popular activity. While exercising in the gymnasiums, the perspiration resulted from the exercising not only keeps the metabolism of human body in good condition, but also keeps human body in good shape. There are various kinds of exercise machines, among which an exercise machine for press exercise is common in the gymnasiums.

[0003] As shown in FIG. 1, a conventional exercise machine 1 for the press exercise is primarily installed with a press device 3 on a support frame 2 of the exercise machine 1. The press device 3 is combined with a plurality of pulleys 5 by a traction cable 4 and then is connected with a movable weight set 6. When a user is doing the press exercise, the user's two hands are required to hold a gripping bar 7 of the press device 3 and to synchronically press upwardly in order to overcome the opposite force generated by the movable weight set 6, thereby the exercise is done successfully. However, the press device 3 of the conventional exercise machine 1 is a single component and is pivotally mounted on a top side of the support frame 2, such that the press exercise can be done only synchronically by the user's two hands instead of one hand alternating with the other hand. So it's quite boring for the user to operate the conventional exercise machine 1. Additionally, the press device 3 can be only operated along a fixed direction such that the user can only work out at a fixed portion of his/her body. Accordingly, the conventional exercise machine 1 cannot be operated multi-directionally so as not to be provided with multi-functions.

SUMMARY OF THE INVENTION

[0004] The primary objective of the present invention is to provide a press device of an exercise machine, wherein the press device is composed of two press arms, which can be individually or synchronically operated for press exercise, thereby the exercise machine of the present invention can be preferably diversely operated.

[0005] The secondary objective of the present invention is to provide a press device of an exercise machine, wherein the press device is adjustable in user's exerting angle, thereby the user can do the press exercise at multiple angles.

[0006] The foregoing objectives of the present invention are attained by the press device of the exercise machine including a support frame, a seat assembly and a resistance device. The support frame is composed of a bottom frame, a plurality of struts and a top frame. The seat assembly is mounted on the bottom frame of the support frame. The resistance device is composed of a movable weight set and a plurality of pulleys. The press device includes two corresponding press arms, which can be respectively or synchronically operated and are bilaterally pivotally mounted on the top frame of the support frame and are connected with the resistance device. The two press arms respectively have a lever arm, a gripping bar, and a pivot joint, wherein the pivot joint is mounted between the lever arm and the gripping bar for integrally pivotally interconnecting the lever arm and the gripping bar. Accordingly, the gripping bar can be operated to pivot at an adjustable angle relatively to the lever arm by the pivot joint, thereby the user can adjust a pivoting angle of the gripping bar relatively to the lever arm and do the press exercise at multiple angles.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Referring to FIGS. 2-3, the present invention provides a press device 41 of an exercise machine 10. The exercise machine 10 includes a support frame 11, a seat assembly 21, a resistance device 31, and the press device 41.

[0013] The support frame 11 includes a substantially T-shaped bottom frame 12, a front strut 14 and two rear struts 16, which are respectively mounted on the bottom frame 12, wherein the front strut 14 is mounted at the middle section of the bottom frame 12. A top frame 18 is fixedly mounted at a top end of the front strut 14. The two rear struts 16 have two bottom ends respectively connected with two top ends of a rear side of the bottom frame 12 and two top ends connected with the top frame 18.

[0014] The seat assembly 21 is mounted on the support frame 11 and has a back support 22, a padded seat 24 and a leg extension station 26. The back support 22 and the padded seat 24 are respectively mounted on the front strut 14 and the bottom frame 12 for a user sitting thereon. The leg extension station 26 is mounted on a top end of a front side of the bottom frame 12 for the user's two legs grasping or stepping.

[0015] The resistance device 31 includes a movable weight set 32, a plurality of pulleys 34 and a traction cable 36, wherein the movable weight set 32 is interconnected with the pulleys 34 by means of the traction cable 36. The user can do press exercise by exerting against resistance, which is generated by the movable weight set 32. Here to be clarified, the way and the operating status of traction between the movable weight set 32 and the pulleys 34 are well known to people who are skilled in the art and will not be described in details thereafter.

[0016] The press device 41 is composed of two corresponding press arms 42, which can be respectively or synchronically operated. The two press arms 42 are bilaterally respectively pivotally mounted on a front end of the top frame 18 of the support frame 11 and are installed with a plurality of pulleys 34 thereon. The two press arms 42 are interconnected with the resistance device 31 by the traction cable 36, thereby the two press arms 42 of the press device 41 can respectively drive the movable weight set 32 of the resistance device 31 to move. Accordingly, the user can do the press exercise by his/her two hands alternately operating the press arms 42 of the press device 41 such that the present invention includes preferably multiple operating ways. Each of the press arms 42 is composed of a lever arm 43, a gripping bar 44 and a pivot joint 45, wherein the lever arm 43 is laterally pivotally mounted on the top frame 18 of the support frame 11 at a top end thereof, and the pivot joint 45 is mounted between a bottom end of lever arm 43 and a top end of the gripping bar 44, thereby the lever arm 43 is integrally pivotally interconnected with the gripping bar 44. Additionally, the pivot joint 45 is adjustable to drive the gripping bar 44 to pivot at an adjustable angle relatively to the lever arm 43, thereby the user can operate the gripping bar 44 to pivot at the adjustable angle relatively to the lever arm 43 so as to do the press exercise at different angles. Besides, the gripping bar 44 is designed to be crook-shaped at a distal end thereof for the user easily holding.

[0017] Referring to FIG. 4, the press arms 42 of the press device 41 are respectively pivotally mounted on two sides of the top frame 18 of the support frame 11 so as to respectively drive the movable weight set 32 of the resistance device 31 by means of the pulleys 34 of the press arms 42 and the traction cable 36. Accordingly, when the user operates the press device 41, the press arms 42 can be operated respectively alternately by the user's right hand and left hand to pull the movable weight set 32 of the resistance device 31 such that the user can do the press exercise successfully and the present invention can be operated preferably diversely. Alternatively, the press arms 42 of the press device 41 can be synchronically operated to drive the movable weight set 32 of the resistance device 31, and meanwhile, the resistance generated by the movable weight set 32 is evenly held by the user's two hands.

[0018] Moreover, referring to FIG. 5, the gripping bar 44 of the press arms 42 is pivotally connected to the lever arm 43 by the pivot joint 45 so as to pivot at different angles relatively to the lever arm 43 and then the user can do the press exercise at multiple angles.

[0019] Therefore, the present invention includes advantages described below:

[0020] 1. The press arms of the press device in accordance with the present invention can be operated individually or synchronically, thereby the exercise machine can be operated in multiple ways.

[0021] 2. The press device of the present invention is adjustable in the angle, at which the user' two hands exerting on the press device, thereby the user can do the press exercise at multiple angles.
