Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a weightlifting bed that is easy to remove from the bar. Background Technology

[0002] A weightlifting bench, also known as a barbell rack or bench press rack, is a fitness device used for chest training with barbells.

[0003] For example, Chinese patent document CN222266034U discloses a multifunctional folding weightlifting bed, including a base. Two uprights are symmetrically fixedly installed on the outer side of the base, and a barbell holder is fixedly installed on the top of each upright. A reinforcing plate is fixedly connected between the two uprights. Through the cooperation between the guide rod and guide block, as well as the connecting shaft and sleeve, the support plate can easily drive the supine board to rise and fall. Through the cooperation between the sliding plate, the U-shaped round rod, and the spring, two insert rods can be inserted into two corresponding insertion holes, which can fix the uprights to the frame and thus fix the position of the supine board, making it easy to adjust the height of the supine board according to the user's needs.

[0004] However, when performing a bench press, the user first needs to lie flat on a flat bench with their eyes vertically aligned with the barbell. After gripping the barbell, the user lifts it off the rack by pushing their shoulders towards the barbell and applying force. Then, by rotating their upper arms, the barbell is brought to a position aligned with their chest, allowing them to begin the bench press. Therefore, when using a weightlifting bench, the user needs to perform a shoulder push and apply force when lifting the barbell, making the process more strenuous and affecting their performance during the subsequent bench press. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a weightlifting bed that is easy to remove the bar, so as to ensure the user's training state during bench press.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weightlifting bench that facilitates barbell release, comprising a flat bench, a base on one side of the flat bench, symmetrically arranged support rods and symmetrically arranged placement rods above the base, the support rods being vertically fixed to the base and used to support the placement rods, one end of the placement rod being rotatably connected to the base, and the other end being provided with a placement hook for placing the barbell, a barbell release device being provided between the flat bench and the support rods, the barbell release device being used to drive the placement rods to rotate in a direction away from the support rods, so that the barbell is rotated in a direction away from the support rods to release the barbell.

[0007] The present invention is further configured such that: the step-out bar device includes a foot pedal, one end of which is rotatably connected to the bottom of the flat bench; a tension spring is provided between the support rod and the placement rod, one end of which is fixed to the outer wall of the support rod and the other end of which is fixed to the outer wall of the placement rod; the tension spring is used to drive the placement rod to reset; a transmission mechanism is provided between the foot pedal and the placement rod, and the foot pedal drives the placement rod to rotate away from the support rod through the transmission mechanism.

[0008] The present invention is further configured such that: the transmission mechanism includes a pulley block and a pull rope, one end of the pull rope is fixed to the placement rod and the other end is fixed to the foot pedal rod, and the pull rope is coupled with the pulley block to form a transmission cooperation between them.

[0009] The present invention is further configured such that: a horizontally extending guide rail is provided between the support rod and the placement rod, the guide rail is fixed to the base, a slider is coupled on the guide rail, the slider can form a sliding fit with the guide rail, a connecting rod is provided between the slider and the placement rod, one end of the connecting rod is rotatably connected to the slider, and the other end is rotatably connected to the placement rod.

[0010] The present invention is further configured such that: the foot pedal is provided with a horizontally extending extension rod symmetrically at the end of the side away from the flat bench.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Because of the rotatable bar that is driven by a step-out mechanism, during bench press training, the user simply lies flat on a bench, grips the barbell, and then uses the step-out mechanism to rotate the bar away from the support bar. This allows the barbell to move to a position opposite to the user's chest. After the bar returns to its original position, the barbell is extended, and the user can immediately begin bench press training. Therefore, this effectively solves the technical problem of the effort required for extending the barbell in existing technologies, thus ensuring the user's training state during bench press.

[0015] Figure 3 This is a schematic diagram of the main structure of this utility model. Detailed Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] First, the correct bench press technique: The user should lie flat on a flat bench 1 with their eyes vertically aligned with the barbell 100. After gripping the barbell 100, the user should lift the barbell 100 by extending their shoulders towards the barbell and applying force, thus detaching it from the barbell rack. Then, by rotating the upper arms, the barbell 100 will be positioned opposite the user's chest. The user can then begin the bench press. It is evident that the user needs to perform a shoulder extension and force application when lifting the barbell, making the process more strenuous and affecting subsequent bench press performance.

[0019] To avoid straining when manually releasing the bar, such as Figures 1 to 3 As shown, this utility model discloses a weightlifting bed with an easy-to-release barbell. Its structure mainly includes a flat bench 1, which is horizontally positioned for the user to lie flat. A base 2 is located on one side of the bench 1. Symmetrically arranged support rods 3 and placement rods 4 are located above the base 2. The support rods 3 are vertically fixed to the base 2 and support the placement rods 4. One end of the placement rod 4 is rotatably connected to the base 2 via a hinge shaft, and the other end extends upward and is equipped with a placement hook 5 for placing a barbell 100. An anti-slip rubber layer can be added to the inner side of the placement hook 5 to enhance stability. A step-release device is provided between the bench 1 and the support rods 3. This device drives the placement rods 4 to rotate away from the support rods 3, thereby allowing the barbell 100 to be released from the bench.

[0020] The specific structure of the step-out barbell device mainly includes a foot pedal 61 and a transmission mechanism. One end of the foot pedal 61 is rotatably connected to the bottom of the flat bench 1 via a hinge shaft, and the other end is a long rod-shaped structure. In addition, a tension spring 62 is provided between the support rod 3 and the placement rod 4. One end of the tension spring 62 is fixed to the outer wall of the support rod 3, and the other end is fixed to the outer wall of the placement rod 4. Under normal conditions, the tension of the tension spring 62 keeps the placement rod 4 in a position against the support rod 3, ensuring that the barbell bar 100 is stably placed in the placement hook 5. Furthermore, the support of the support rod 3 reduces the pressure on the placement rod 4 from the barbell bar 100.

[0021] The transmission mechanism includes a pulley block 63 and a pull rope 64. The pulley block 63 consists of a fixed pulley and a movable pulley. One end of the pull rope 64 is fixed to the outer wall of the placement rod 4, and the other end passes through the pulley block 63 and is fixed to the outer wall of the foot pedal 61. When the user presses down on the end of the foot pedal 61 away from the flat bench 1, the foot pedal 61 rotates downward around the connection point with the flat bench 1, thereby driving the pull rope 64 to pull the placement rod 4 to rotate around the connection point with the base 2 in a direction away from the support rod 3. This causes the barbell bar 100 to move outward with the placement hook 5 to complete the barbell release action. The trajectory of the barbell bar 100 moving due to the rotation of the placement rod 4 and the trajectory of the barbell bar 100 moving due to the user's own release are both arc-shaped motion trajectories. Thus, during bench press training, the user simply lies flat on the bench 1, grips the barbell 100, and then uses the step-out mechanism to rotate the placement bar 4 away from the support bar 3. This rotation moves the barbell 100 to a position opposite to the user's chest. After the placement bar 4 returns to its original position, the barbell 100 is extended, allowing the user to directly begin bench press training, reducing the physical exertion on the hands when manually extending the bar. When the foot pedal 61 is released, the tension spring 62 causes the placement bar 4 to return to its original position, and the foot pedal 61 returns to its initial position under the action of the transmission mechanism. Furthermore, a torsion spring can be installed at the connection between the foot pedal 61 and the bench 1 to further facilitate the return of the foot pedal 61.

[0022] To further optimize the movement trajectory of the placement rod 4, a horizontally extending guide rail 7 can be installed between the support rod 3 and the placement rod 4, with the guide rail 7 fixed to the upper surface of the base 2. A slider 8 is slidably fitted on the guide rail 7, and the slider 8 is hinged to the placement rod 4 via a connecting rod 9. When the placement rod 4 is pulled and rotated by the pull rope 64, the connecting rod 9 pushes the slider 8 to slide along the guide rail 7, thereby limiting the rotation trajectory of the placement rod 4, preventing lateral deviation, and ensuring a smooth bar deployment process. In addition, to improve the ease of stepping, a horizontal extension rod 611 can be symmetrically welded to the end of the foot pedal 61 away from the flat bench 1. This facilitates contact between the user's foot and the foot pedal 61, increasing the contact area and making it easier for the user to trigger the bar deployment action.

[0023] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
