Description

Self-Starting Bench Press

technical field

The utility model relates to a special device for bodybuilding training, in particular to a self-starting type bench press.

Background technique

Bench press is the abbreviation of supine press, also known as bench press or bench press. It mainly trains pectoralis major, pectoralis minor, anterior deltoid, triceps and anconeus, and also trains serratus anterior, biceps, coracobrachialis and forearm muscles. Bench press involves many bones and muscles, especially for the development of upper limb extensors and pectoralis major, which is unmatched by other movements. Therefore, it is known as the "king of movements" and is one of the most basic movements in bodybuilding training. A prescribed action for lifting competitions is divided into barbell bench press, dumbbell bench press and rack bench press. In the standard heavy weight bench press training, the barbell bench press and dumbbell bench press must always be protected by someone so as not to be injured by the barbell or dumbbell when the trainer makes mistakes or fails. The rack-type bench press is relatively safe because the trajectory of the weight is restricted by the rack, and the weight of the bench press will not hit the trainer even if it falls. When training with light weight or medium weight, the trainer can complete it independently, but when training with heavy weight bench press, the trainer cannot complete the self-starting, and still needs someone to give the trainer a starting boost at the initial stage before starting the bench press training . In the normal heavy weight bench press training, the starting power does not need to be very large, but it always needs someone to help to complete it, which not only takes up manpower, but also makes the training inconvenient.

Contents of the invention

The purpose of the utility model is to propose a technical scheme of a self-starting type bench press in order to solve the disadvantage that it cannot be started by itself during heavy weight bench press training and needs someone to provide start assistance.

The scheme of the utility model is: a self-starting type bench press, on the support, a barbell is rotatably connected to the barbell frame, and the support is provided with a push bed, which is characterized in that the barbell frame is fixedly connected to the pull rod, and the lower end of the pull rod is connected to the steel barbell. Rope is rotatably connected to the pedal frame at the left end of the support, the left side and the right side of the pedal frame are provided with pedal rods, and the other end of the steel rope is connected below the pedal frame.

The length H of the pull rod is greater than or equal to the distance F from the connecting point of the pull rod and the barbell rack to the barbell axis, H≥F.

Two steel ropes are connected between the lower end of the pull rod and the bottom of the pedal frame.

The structure of the rotatable connection pedal frame at the left end of the support is that the bracket is fixedly connected with the rotating shaft seat, the rotating shaft seat is rotatably connected with the rotating shaft, and the pedal frame is rotatably connected with the rotating shaft.

The left side of the pedal frame is provided with a pulley support frame, and the lower end of the pulley support frame is provided with rotatable pulleys with the same number as the steel ropes.

The utility model is improved on the basis of the traditional barbell bench press. It mainly fixes a pull rod on the barbell frame, the lower end of the pull rod is connected with a pull rope, and the other end of the bracket is rotatably connected with a pedal frame. The side is provided with a pedal bar which is convenient to push forward with both feet, and the other end of the drawstring is connected to the bottom of the pedal frame. When the pedal bar is pushed forward with both feet, the pedal bar moves around the rotating shaft, the pull rope pulls the pull bar, and the pull bar drives the barbell rack to rotate counterclockwise, driving the barbell to move upwards, and realizes self-starting bench press. In order to make starting relatively labor-saving, the utility model designs the length of the pull bar to be greater than or equal to the distance from the connection point of the pull bar and the barbell rack to the barbell rotating shaft. In order to make the pull rod stressed evenly, the utility model designs two stay ropes connecting the pull rod and the pedal frame. In order to stabilize the position of the stay cord and also make the stay cord in a tensioned state, the utility model is provided with a pulley supporting frame on the left side of the pedal frame, and the lower end of the pulley support is provided with a pulley. When in use, the utility model puts the trainer's calf forward stretching pedal to push the rod, and pulls the pull rod upward through the pull cord to realize the self-starting of the bench presser. The utility model is reasonable in design, simple in structure, safe and reliable, and convenient to use, and realizes that the bench presser can start by himself without assistance from others during heavy weight bench press training. It saves manpower and facilitates training.
