Description

Technical Field

[0001] This invention relates to the field of fitness equipment rack technology, and more particularly to a modular fitness equipment rack. Background Technology

[0002] With the popularization of fitness concepts, the demand for multifunctional and adaptable fitness equipment is increasing in home gyms and small fitness venues. As a core strength training method, barbell training requires its corresponding equipment racks. Currently, barbell bench press racks on the market are modularly designed for easy installation and transportation, making them convenient to install and use. The components are disassembled, simplifying the assembly process and allowing for setup without specialized tools. This adapts to the flexible layout of different home spaces and small venues, while reducing damage rates and logistics costs during transportation, meeting the current demand for convenient fitness. However, existing barbell racks have significant shortcomings in their safety protection structures. Some racks lack effective anti-slip and anti-impact protection devices for the barbell. If users experience fatigue or operational errors during training, causing the barbell to slip, it can easily lead to personal injury. Summary of the Invention

[0003] The purpose of this invention is to address the significant deficiencies in the safety protection structure of existing barbell racks mentioned in the background art above. Some equipment racks lack effective anti-drop and anti-smashing protection devices for barbells, which can easily cause personal injury if the user experiences physical exhaustion or operational errors during training, leading to the barbell slipping.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A modular fitness equipment rack is characterized by comprising a base, a vertical frame, and a support component. A reclining stool is mounted on the front end of the base. The vertical frame is mounted on the base, and an extended plate is fixed on the vertical frame. The extended plate has symmetrically distributed mounting slots along its longitudinal direction. The support component can be installed at different height positions on the extended plate through the mounting slots. The support component includes a support plate, and a limiting plate is fixed on the support plate. The support plate and the limiting plate form a support space to support a barbell.

[0005] Preferably, the support plate is U-shaped, and multiple mounting rods are fixedly connected to the two inner sides of the support plate. The mounting groove includes a horizontal groove and a vertical groove that connects to the horizontal groove. The mounting rods enter the vertical groove through the horizontal groove.

[0006] Preferably, a safety tube fixed to the support plate is provided on the lower side of the limiting plate, and the safety tube extends forward and is parallel to the recliner.

[0007] Preferably, the front end of the safety tube has a blocking portion.

[0008] Preferably, a protective plate is rotatably connected to the safety tube, and one side of the protective plate is flush with the vertical inner side of the limiting plate.

[0009] Preferably, the protective plate has an integrally formed inclined plate that is tilted forward to increase the barbell's range of motion.

[0010] Preferably, a rotating shaft is fixed on the protective plate, the rotating shaft is rotatably connected to the safety tube, a gear is fixed on the rotating shaft, a rack meshes with the gear, a threaded sleeve is rotatably connected to the safety tube, a screw is fixed to one end of the rack, and the screw is threadedly connected to the threaded sleeve.

[0011] Preferably, the outer expansion plate has an anti-detachment groove with a connecting horizontal groove, and the end of the mounting rod has a protruding anti-detachment part that enters the anti-detachment groove.

[0012] Preferably, a roller for contacting and supporting the barbell is provided between the limiting plate and the support plate.

[0013] Preferably, the top of the limiting plate exceeds the height of the roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The limiting plate of the support component and the support plate form a stable support space, and the top of the limiting plate is higher than the height of the roller, ensuring that the barbell bar has entered the limiting range before being released, thus preventing the barbell from slipping laterally. The anti-slip groove of the outer expansion plate cooperates with the protruding anti-slip part of the mounting rod, combined with the inclined surface at the connection of the horizontal and vertical grooves, which can not only facilitate the installation of the support component, but also prevent it from slipping laterally, further ensuring the stability of the support and reducing the risk of the barbell slipping from the source.

[0015] The protective plate and the inclined plate work together to guide the falling barbell smoothly into the range of the limiting plate, while also expanding the barbell's range of motion to prevent jamming during operation. The safety tube extends forward parallel to the bench, directly catching any accidentally dropped barbell. Its surface rubber pads effectively cushion the impact force of the barbell while increasing its rolling resistance, forming the first line of defense. The stop at the front of the safety tube prevents the barbell from detaching from the tube, avoiding secondary sliding and injury. Together with the protective plate and the inclined plate, they form a double layer of protection, significantly reducing the risk of the barbell injuring the user.

[0016] The protective plate can be flexibly rotated and locked through the cooperation of a rotating shaft, gears, racks, screws and screw sleeves. When in use, it can be unfolded into a vertical position to form protection. When not in use, it can be stored in the storage slot, which does not take up extra space and can be flexibly switched according to training needs, taking into account both protection and usage flexibility.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] Please see Figures 1-5 A modular fitness equipment rack includes a base 1, a vertical frame 2, and a support component 6. A reclining stool 3 is installed on the front end of the base 1. A footboard 11 is fixed on the base 1, which is used for standing and lifting barbells 7. The surface of the footboard 11 is provided with anti-slip texture to increase the friction of the foot and prevent slipping during standing training. The vertical frame 2 is installed on the base 1 and is fixed to the base 1 with detachable bolts for easy disassembly, transportation, and assembly. An expansion plate 4 is fixed on the vertical frame 2, and symmetrically distributed mounting grooves 5 are opened on the longitudinal direction of the expansion plate 4.

[0029] The support component 6 is installed at different heights on the outer expansion plate 4 via the mounting groove 5. The support component 6 supports the barbell 7. The support component 6 is modular, making it easy to install at different heights to meet the needs of different people. The support component 6 includes a support plate 61, which is U-shaped. The outer expansion plate 4 is also U-shaped and is fitted onto the outer expansion plate 4. The outer expansion plate 4 is laterally limited, thereby maintaining stability and increasing safety. A limit plate 611 is fixed on the support plate 61. The limit plate 611 is L-shaped. The support plate 61 and the limit plate 611 form a support space to support the barbell 7. A roller 62 is provided between the limit plate 611 and the support plate 61 to contact and support the barbell 7. The roller 62 is located within the support space, and the axis of the roller 62 is perpendicular to the circumference of the barbell 7, so that the resistance is small when the barbell 7 moves laterally. The top of the limiting plate 611 exceeds the height of the roller 62. The excess portion ensures that the barbell 7 has entered the range of the limiting plate 611 before it is released, increasing the safety of the barbell 7 falling back.

[0030] Multiple mounting rods 612 are fixedly connected to both sides of the inner side of the support plate 61, with at least two mounting rods 612 on each side to ensure stability. The mounting groove 5 includes a horizontal groove 51 and a vertical groove 52 connecting the horizontal groove 51. The mounting rods 612 enter the vertical groove 52 through the horizontal groove 51. The outer expansion plate 4 has an anti-detachment groove 53 connecting the horizontal groove 51. The end of the mounting rod 612 has a protruding anti-detachment part 613 that enters the anti-detachment groove 53. The connection between the horizontal groove 51 and the vertical groove 52 has an inclined surface 54, which facilitates the entry of the mounting rod 612 into the vertical groove 52. When the support plate 61 moves up and falls back down, the inclined surface 54 facilitates the fall of the mounting rod 612, preventing the support plate 61 from detaching laterally. The mounting rod 612 enters the outer expansion plate 4 through the horizontal groove 51 and the anti-detachment groove 53, and then falls into the bottom of the vertical groove 52. At this time, the support component 6 is stable both laterally and vertically.

[0031] A safety tube 63, fixed to the support plate 61, is provided on the lower side of the limiting plate 611. The safety tube 63 extends forward and is parallel to the reclining bench 3. The safety tube 63 is used to contact the falling barbell 7, thereby preventing the barbell 7 from hitting the person. The front end of the safety tube 63 has a blocking part 631 to prevent the barbell 7 from detaching from the safety tube 63. The safety tube 63 has a rubber pad 632 for cushioning and increasing rolling resistance.

[0032] A protective plate 64 is rotatably connected to the safety tube 63. One side of the protective plate 64 is flush with the vertical inner side of the limiting plate 611, so that when the barbell 7 falls into the limiting plate 611 after contacting it, it can enter the limiting plate 611 along the protective plate 64.

[0033] The protective plate 64 has an integrally formed inclined plate 65. The inclined plate 65 is tilted forward, which increases the distance between the inclined plate 65 and the outer expansion plate 4, thereby increasing the movement space of the barbell 7. The safety tube 63 is provided with a storage groove 633 for the protective plate 64 and the inclined plate 65. When stored, the upper surface of the protective plate 64 is flush with the top surface of the safety tube 63, thereby increasing the contact area for receiving the barbell 7.

[0034] A rotating shaft 641 is fixed to the protective plate 64, and the rotating shaft 641 is rotatably connected to the safety tube 63. A gear 66 is fixed to the rotating shaft 641, and a rack 67 meshes with the gear 66. A threaded sleeve 68 is rotatably connected to the safety tube 63. A screw 69 is fixed to one end of the rack 67, and the screw 69 is threadedly connected to the threaded sleeve 68. The safety tube 63 has a receiving groove for mounting the gear 66, rack 67, screw 69, and threaded sleeve 68. The receiving groove limits the rack 67, allowing it to move linearly. The rack 67 is locked by the screw 69 and the threaded sleeve 68, thereby locking the protective plate 64.

[0035] In use, rotating the screw sleeve 68 causes the screw 69 to move, which in turn moves the rack 67. The rack 67 then rotates the gear 66, causing the protective plate 64 to rotate out of the storage slot 633. One side of the protective plate 64 contacts the vertical surface of the storage slot 633, preventing the screw sleeve 68 from rotating. At this point, the protective plate 64 is in a vertical position. The protective plate 64 and the inclined plate 65 allow the barbell 7 to move within a confined space. If the barbell accidentally moves out of the protective plate 64's restraint, it will be caught by the safety tube 63. The combination of the protective plate 64 and the safety tube 63 makes the use of the barbell 7 safer. When the protective plate 64 is no longer needed, rotating the screw sleeve 68 allows the protective plate 64 and the inclined plate 65 to retract into the storage slot 633.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
