Strength training machine for training the triceps muscles

Abstract

A strength training device for training the triceps muscles, in which a trainee 2, supported on a seat 19 and against the backrest 20, starts from the exercise's starting position (Fig. 1) by moving the forearms 15 around the elbow joint and the upper arms 13 around the shoulder joint, lifting a weight over several pulleys 10, 12, 16, 17. To transmit the movement, the handle lever arm 31 is rotatably connected to the main lever arm 32 via the connecting axis 33. The main lever arm 32 has a pivot axis 5, which is rotatably mounted on the frame 1 of the strength training device by two flange bearings 24 (Fig. 7 / Two-lever mechanism and Fig. 2).8), is connected to weight plates of a weight package 11 and has a support bracket 6 at one end for holding the handles 7 and for holding the pulling device 9, characterized in that the connection of the pulling device 9 to the support bracket 6 is located on the outside of the handle lever arm 31 at the level of the pulleys 12, 16, 17 and the trainee 2, by means of the connection of the handles 7 to the support bracket 6 on the inside of the handle lever arm 31, engages the pulling device 9, the vertical pulley 16 and the horizontal pulley 17 for a change of direction and load during the execution of the movement sections B1-B5 (Fig. 2-Fig. 6) for the maximum triceps load of all three muscle heads, from the maximum extension to the peak contraction.
