Description

Drop-type power leg press

[0001] The present invention relates to a drop-type power leg press, and more specifically, to a drop-type power leg press for lower body exercise that allows users to perform efficient leg exercises by guiding heavy weights to the maximum range of motion, ranging from beginners to professional athletes, so that the user can increase and decrease the weight on their own.

[0002] Generally, exercising regularly is very important for improving muscle strength and endurance. However, the problem is that modern people do not find it easy to exercise due to their busy schedules, resulting in insufficient physical activity.

[0003] Up until now, strength training equipment has been designed to collect 12 to 15 10kg weights in one place and connect them with ropes to transfer weight to various exercise machines. This results in the equipment being excessively bulky and heavy. Furthermore, as a user's muscle mass increases and they become accustomed to the exercise, they increase the weight of the weights; however, this does not allow for precise weight increases and can only be done in increments of 10kg, which poses a constant risk of injury.

[0004] In particular, the Power Leg Press, an essential exercise for lower body muscle growth, is a piece of equipment that replicates the effects of a squat by repeatedly performing lower body exercises of pushing and lowering heavy weights diagonally while seated on the machine.

[0005] Although progressive overload and maximum range of motion are essential conditions for muscle growth, the power leg press applies maximum load when lowering heavy weight with the legs from the point of maximum lowering at around 90 degrees, and also when turning and pushing back up to around 90 degrees. However, in this section where maximum load is applied, the fear of being crushed by the weight and the concern for injury prevent continuous weight increase, leading to power leg press exercises being performed with a limited range of motion.

[0006] Consequently, whether exercising with a partner or alone, one had no choice but to perform a drop set method of reducing the weight by 30-40% after performing to failure. Although weight training should be gradually increased for effective exercise, the drop set method of reducing weight resulted in a problem that it was not effective for muscle growth in the legs.

[0007] Consequently, there was a demand for a power leg press that allows one to exercise with heavy weights and a maximum range of motion alone, without the aid of a helper.

[0008] Meanwhile, the bench press is considered a chest exercise, the deadlift a back exercise, and the squat a lower body exercise, making them the three major exercises of weight training. The squat, a lower body exercise performed in the form of weightlifting by attaching weights to a free weight bar and sitting down and standing up, has the problem of being susceptible to back, knee, and ankle injuries if performed with incorrect posture or excessive weight. In particular, the power leg press, an essential exercise for lower body muscle growth, is a piece of equipment that replicates the effects of a squat by allowing the user to sit on the machine and push and lower heavy weights diagonally.

[0009] The present invention aims to overcome the problem of the legs being crushed by the weight when pushing and lowering weight with the legs during exercise using a power leg press, as the legs fail to withstand or push off at the point where maximum load is applied to the legs, and the resulting physical injury and mental fear. It provides a drop-type power leg press that allows the user to increase the weight to a desired level while simultaneously adjusting the maximum load distance according to the user, and enables the user to continuously increase the weight to the maximum range of motion by dropping the set weight at a variable position set by the user.

[0010] The present invention aims to provide a drop-type power leg press comprising a drop control unit means in which the weight plate of the drop power leg press is composed of a foot plate weight part and a drop weight part, and a ratchet stopper is formed in the same diagonal direction as the weight plate and stops the drop weight part at a position that is variably set in the section where the leg pushes down to drop the set weight.

[0011] The present invention aims to provide a drop-type power leg press in which a weight bar is installed in each of the footplate weight section and the drop weight section, and the weight can be adjusted by setting the weight by inserting or removing weight plates from the weight bars.

That is, it shows the state in which the drop is released by setting the ratchet stopper (64) to the release position of the 0th grade level and pushing the footplate with the leg to push out the footplate weight portion (106) and the drop weight portion (110).

[0091] To look more specifically, first, a stopper frame (22) is installed in the horizontal direction, a drop adjustment unit means (112) is installed in the middle part of the stopper frame (22), and a foot weight part (106) and a drop weight part (110) are installed on the upper part of the stopper frame (22).

[0092] The drop weight portion (110) is positioned at the right end of the stopper frame (22), and the footplate weight portion (106) is pushed to contact the left side of the drop weight portion (110). The footplate weight portion (106) and the drop weight portion (110) are fitted onto the guide rods (42, 43) of the guide portion (108) and installed so as to be movable in the left and right directions.

[0093] The ratchet stopper (64) of the above drop adjustment unit means (112) is set to be located at grade 0 of the setting part (62).

[0094] FIG. 3(b) is a drawing showing the state in which a user lowers a footrest while supporting the weight of the footrest weight part (106) and the drop weight part (110), and the footrest weight part (106) and the drop weight part (110) move to the left, and at this time, the drop weight part (110) comes into contact with the ratchet stopper (64) of the drop control unit means (112) and stops.

[0095] At this time, the drop adjustment unit means (112) is set to a release position of grade 0, and the stopper tip (52) of the stopper (50) is in contact with the upper right side of the ratchet stopper (64) to prevent it from moving forward and is stopped.

[0096] Next, FIG. 3(c) is a drawing in which the ratchet stopper (64) of the drop adjustment unit means (112) is moved to set the position of grade 8, and the footplate weight part (106) moves to the left due to its own weight, and the user supports the footplate weight part by supporting the footplate with their legs, and at the same time, the drop weight part (110) also moves to the left due to its own weight in the direction of the arrow and is stopped by the stopper tip (52) at the set grade 8 stage.

[0097] That is, the footplate weight portion (106) slides down along the guide rods (42, 43) while the user supports the footplate with their legs, and the drop weight portion (110) slides down in the left direction as indicated by the arrow and is stopped by the ratchet stopper (64).

[0098] At this time, the ratchet stopper (64) of the drop adjustment unit means (112) is set to the 8th grade position, and the locking pin (68) is inserted into the fixing groove (60) formed between the fixing tips (58) and fixed.

[0099] Meanwhile, normally, the foot weight and drop weight as described above are stopped at the set grade, and in that state, the ratchet stopper is set to the desired stage and the foot weight is lowered and pushed out.

[0100] And, a weight drop section (A) is formed between the above-mentioned foot weight section (106) and the drop weight section (110). In the weight drop section (A), the ratchet stopper (64) is first set to the 8th grade level, and then the weight foot section (110) is stopped at the 8th grade level and the foot weight section (106) continues to be supported by the legs and descends, thereby forming a predetermined section of the weight drop section (A).

[0101] In the above weight drop section (A), only the footplate weight part (106) needs to be pushed up with the legs, and in the 8th grade level or higher where the drop weight part (110) is stopped, the footplate weight part (106) and the drop weight part (110) can be pushed up simultaneously to perform heavy weight exercises.

[0102] FIG. 4 is a planar operation diagram showing the structure of the drop-type power leg press of the present invention, and is a drawing showing a rattling type configuration with one location installed in the center.

[0103] First, referring to FIG. 4(a), FIG. 4(a) shows the initial state in which the drop weight portion (110) is positioned upward and the footplate weight portion (106) is also moved upward. That is, it shows the state in which the drop is released by setting the ratchet stopper (64) to the release position at grade 0 and pushing the footplate with the leg to push out the footplate weight portion (106) and the drop weight portion (110).

[0104] A ratchet stopper (64) is installed with a drop control unit means (112) in the center to push, lower, and drop the above-mentioned foot weight portion (106), and as shown in FIG. 4(a), guide rods (42) and (43) are installed on the left and right sides, respectively, and the foot weight portion (106) is positioned in the middle of the guide rods (42, 43), and the drop weight portion (110) is positioned at the upper part of the foot weight portion (106).

[0105] And, the stopper block (47) provided at the lower left and right sides of the connecting frame (46) is in contact with the upper part of the connecting frame (39) of the footrest weight part (106).

[0106] The above drop weight portion (110) is provided with a connecting frame (46), and the connecting frame (46) is formed in a U-shape. A stopper tip (52) is formed in the center of the connecting frame (46), and stopper blocks (47) are provided on the left and right end surfaces of the connecting frame (46). The stopper tip (52) is installed to contact the ratchet stopper (64), and the stopper blocks (47) are installed to contact the fixed frame (39) of the footplate weight portion (106). At this time, it is preferable that the stopper tip (52) and the stopper blocks (47) be provided with a soft elastic material having a cushioning or dampening function.

[0107] Next, referring to the illustration in FIG. 4(b), when the drop control unit means (112) is set to the release position of the 0th grade level and the footplate weight part (106) and the drop weight part (110) are lowered downward, the drop weight part (110) is stopped by the drop control unit means (112) and the footplate weight part (106) is fixed by the fixing part (19), allowing the user to safely detach.

[0108] Referring to the illustration in FIG. 4(c), the foot weight portion (106) is moved to the lower end of the guide rod (42, 43) and the drop weight portion (110) is positioned on the upper part of the foot weight portion (106). The drop weight portion (110) is positioned at the set 8th grade level of the drop control unit means (122) so that it stops while coming down, and the user can lower it by moving only the foot weight portion (106) downward. At this time, the foot weight portion (106) can move the distance, i.e., the weight drop section (A), to the position where the drop weight portion (110) is stopped.

[0109] In addition, the footplate weight (106) is located at the bottom, and the drop weight (110) is set up so that it gets stuck and stops at level 8, allowing the user to operate by lowering and pushing up while supporting only the weight of the footplate weight (106), or when reaching the drop weight that has stopped at level 8, the footplate weight (106) and the drop weight (110) are pushed together, thereby enabling heavy weight exercise.

[0110] At the same time, while the drop weight section (110) is stopped, the distance between the footplate weight section (106) and the drop weight section (110) widens, forming a weight drop section (A), and this weight drop section (A) allows the user to safely use only the footplate weight section (106) with low weight.

[0111] Referring to FIG. 4(d), a drop control unit means (112) is installed vertically in the central part of the footplate weight portion (106) and the drop weight portion (110). After the user selects and sets one of the 0-12 grade levels desired by the drop control unit means (112), the drop weight portion (110) is stopped so as to come into contact with the upper part of the drop control unit means (112). That is, the ratchet stopper (64) of the drop control unit means (112) is adjusted and set, showing the state in which the footplate weight portion (106) is pushed upward in the direction of the arrow.
