Description

Adjustable air pressure chest pushing trainer

Technical Field

The utility model relates to a body-building apparatus, in particular to an adjustable air pressure chest-pushing trainer.

Background

The traditional chest pushing training is to train the pectoralis major, the deltoid anterior, the brachial triceps, etc. by selecting a plate or a bell plate as a load and by chest pushing action. However, this resistance may vary with the movement of the handler. For example, resistance often increases at the beginning of the movement due to the inertia of the arm and weight plate itself, and at the end of the movement, the resistance also decreases due to inertia. This change can cause impact injury to the joints of the shoulder and elbow during training. Meanwhile, in the exercise process, the maximum resistance force point and the maximum muscle force point are not synchronous, and the training effect is not ideal.

The utility model discloses a further improvement lies in: the main frame is provided with an instrument frame, and the instrument frame is provided with a display instrument.

The utility model discloses a further improvement lies in: the lower end of the main frame is symmetrically connected with a plurality of groups of height-adjustable feet.

The utility model discloses a further improvement lies in: the cushion frame is a height-adjustable cushion frame.

Compared with the prior art, the utility model has the advantages of it is following:

simple structure, design benefit through using atmospheric pressure as resistance source, can be in the in-process of moving, provides stable unchangeable resistance for muscle. Secondly, because the resistance is stable in the movement process, the maximum force point of the resistance and the maximum force point of the breast muscle are synchronous through the accurate calculation of the mechanical connecting rod, and the training effect can be greatly improved.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an action curve during the exercise of the air resistance;

reference numbers in the figures: 1-main frame, 2-left push arm, 3-right push arm, 4-right push arm, 5-right handle arm, 6-cylinder, 7-instrument frame, 8-display instrument, 9-cushion, 10-back cushion, 11-supporting leg, 12-cushion frame, 13-pressing handle.

The specific implementation mode is as follows:

in order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

Fig. 1-2 show a specific embodiment of the adjustable pneumatic chest-pushing trainer of the present invention: the main frame 1 is symmetrically provided with a group of cylinder mounting frames 11, a cylinder 6 is mounted on the cylinder mounting frames 11, the head of the cylinder 6 is connected with the rear ends of a left push arm 2 and a right push arm 3, the front end of the left push arm 2 is connected with a left handle arm 4, the front end of the right push arm 3 is connected with a right handle arm 5, pressing handles 13 are arranged on the left handle arm 4 and the right handle arm 5, the functions of inflation and deflation of the cylinder are realized through the pressing handles 13, a cushion 9 is mounted on the cushion frame 12, and a back cushion 10 is mounted on the back cushion frame; an instrument frame 7 is installed on the main frame 1, and a display instrument 8 is installed on the instrument frame 7; the lower extreme symmetric connection of body frame 1 has the adjustable footing of multiunit height, even the unevenness on ground, also can transfer stable state, cushion frame 12 is height-adjustable cushion frame, and the user can be according to self height, through pressing the spanner, adjusts the best position that is fit for oneself training.

The utility model discloses mainly be training user's pectoralis major, deltoid toe-in, brachial triceps etc. before the use, the user sits on cushion 9, adjusts cushion frame 12, adjustment left handle arm 4, adjustment right handle arm 5 to suitable training position according to self training needs, and back of the body pad 10 is hugged closely at the back, presses the plus-minus button on hand, adjusts to suitable training resistance, gets into the training state. Both hands arm promotes left handle arm 4, right handle arm 5, drives left arm 2, the right arm 3 that pushes away and rotates, and left arm 2, the right arm 3 that pushes away link to each other with 6 heads of cylinder, and compression cylinder 6 produces the resistance, and when the training was ended, the resistance was reduced, and the training was ended. The technical parameters required for training can be displayed on the meter 8.

Fig. 2 is a force curve during the exercise of the air resistance. The upper half of the line is the force generated when the force is applied and the lower half is the force generated when the force is released back to the original position. As can be seen in figure 2, the resistance offered by the pneumatic technique of the present product is very stable and varies greatly over a range of motion compared to the resistance offered by conventional weight plates, and this variation can cause significant damage to the joint and connective tissue of the user.

The utility model discloses a first time adopt mechanical linkage to replace cable system before to provide suitable straight line traction force. The utility model provides a resistance curve is designed out through accurate measurement, calculation. It can be seen from the figure that the forces at the beginning and the end are small and the force at some angle in between is the largest. This is because the starting and ending positions are the starting and ending points of the force, and the user is most vulnerable to injury during training and therefore needs to be a little bit smaller. The resistance of the middle section is gradually increased, and the section is the section which is most suitable for exerting force. Therefore, the mechanical linkage is the key protection scope of the patent.

The utility model discloses adapt to the training person of different statures, have cushion adjustment mechanism, the suitability is strong, and the training person can be according to self height, through pressing down the spanner, adjusts the best position that is fit for oneself training.

The utility model discloses simple structure, design benefit through using atmospheric pressure as the resistance source, can be at the in-process of motion, provides stable unchangeable resistance for the muscle. Secondly, because the resistance is stable in the movement process, the maximum force point of the resistance and the maximum force point of the breast muscle are synchronous through the accurate calculation of the mechanical connecting rod, and the training effect can be greatly improved.

The applicant further states that the present invention is described by the above embodiments, but the present invention is not limited to the above embodiments, i.e. the present invention is not limited to the above embodiments, and the present invention can be implemented only by relying on the above methods and structures. It should be clear to those skilled in the art that any improvement of the present invention is to the present invention, and the addition of the equivalent replacement of the implementation method and the steps, the selection of the specific mode, etc. all fall within the protection scope and the disclosure scope of the present invention.
