Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, specifically to a suspension device and its combined application in a strength training device. Background Technology

[0002] Nowadays, people are increasingly health-conscious, and fitness has become an important part of many people's lives. People need different types of fitness equipment to exercise different parts of their bodies, but most fitness equipment on the market currently has only one function and cannot meet people's needs. Multifunctional professional fitness equipment is also large in size, and while pursuing comprehensive functions, it also results in many functions being idle. Moreover, due to its complex design, it often malfunctions during operation and is difficult to repair.

[0003] To improve their physical fitness, people often purchase fitness equipment to exercise at home. However, these fitness equipment are generally limited in function. Some modifications are made to existing fitness equipment, but these modifications often result in complex structures and take up a lot of space. Summary of the Invention

[0004] The present invention proposes a suspension device and its combined application strength training device, which can solve at least one of the above-mentioned technical problems and create simple fitness exercise conditions by utilizing the limited space environment of the home.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A suspension device includes a support surface for supporting the suspension device. The support surface is T-shaped or I-shaped, and can be located at the lintel in a home or office environment. The suspension device includes at least a pair of hooks and a connecting rod. The hooks include a claw and a bushing. The claw has a protruding support end perpendicular to the extension direction of the bushing. The protruding support end and the side surface adjacent to the bushing are connected to the support surface. The claw and the support surface are engaged parallel to each other or backwards. The ends of the pair of hook bushings away from the claws are connected perpendicularly to each other along the extension direction away from the protruding ends of the claws via the connecting rod.

[0006] The claw has a stepped through hole along the center line of the cross section extending away from the protruding end of the claw. The diameter of the through hole closer to the shaft sleeve is smaller than that of the through hole farther away from the shaft sleeve. The shaft sleeve is a built-in hollow cavity and its end is not closed. The stepped through hole is connected to the hollow cavity of the shaft sleeve and is used to fasten the bolt through.

[0007] The connecting rod includes at least one sleeve and at least one set of right-angle connecting arms. The sleeve is a circular through-tube with opposing parallel through holes at its center, perpendicular to the tube wall's extension direction, for fixing a lead screw. A disc with the same inner diameter as the sleeve is fixedly mounted on the lead screw. The two ends of the lead screw, in conjunction with the adjusting ends of the connecting arms, have a positive and negative thread design, allowing unidirectional rotation and bidirectional synchronous extension and retraction. The span can be adjusted according to different support surface distances, and the two hooks will not easily open. A through hole is formed on the disc perpendicular to the lead screw's extension direction, and the through hole has the same diameter as the sleeve's through-hole, for pin fixing. The right-angle connecting arm includes an adjusting end and a free end. The adjusting end is a circular tube. The free end and the adjusting end are respectively provided with a threaded hole for engaging with a fastening bolt and a threaded hole for engaging with a lead screw. The free end of the connecting arm and the hook bushing are adjusted in height by fastening bolts. The adjustment method can be that the free end of the connecting arm and the hook bushing are non-cylindrical, and the fastening bolts are directly adjusted to raise or lower the height; or the free end of the connecting arm and the hook bushing are cylindrical, and the fastening bolts are fixed inside the hook bushing, and the height is adjusted by rotating the bushing.

[0008] The length of the fastening bolt is the sum of the length of the hook bushing and the length of the free end tube of the connecting arm; the length of the sleeve is the sum of the lengths of the two adjusting end tubes of the connecting arm; the total length of the screw is between the length of the sleeve and twice the length of the adjusting end tube of the connecting arm; the outer wall of the sleeve is provided with a hand-holding foam ring; a limiting threaded hole is provided on one side of the outer wall of the sleeve, and the limiting bolt is pressed against the outer wall of the adjusting end of the connecting arm through the limiting threaded hole; the nut of the fastening bolt is a regular polygon, and a plug is provided on the rear side of the nut in the stepped through hole.

[0009] After assembling and suspending the equipment as described above, a pull-up training device is complete.

[0010] A combined strength training device based on the aforementioned suspension device includes a barbell bar, at least two sets of suspension devices, and a cross connector. The two ends of the barbell bar are symmetrically and parallelly fastened to the cross connector on the same side. The cross connector is fastened to the sleeve of the suspension device in the other vertical direction. By adding the barbell bar, a combined training device similar to a horizontal bar is completed.

[0011] Another combined application of the aforementioned suspension device for strength training includes a barbell bar, counterweight A, counterweight B, and at least two sets of connecting rods and cross connectors. The barbell bar is symmetrically and parallelly fastened with cross connectors on both sides. The cross connectors are fastened to the sleeves of the connecting rods in the other vertical direction. At least two counterweights A and / or one counterweight B are connected in series at the free end of the connecting arm. Fastening bolts pass through counterweights B and A in sequence and are threaded into the threaded holes at the free end of the connecting arm.

[0012] The counterweight A has a through hole A at its center, and the counterweight B has two through holes B symmetrically arranged. The distance between the center point of the two through holes B and the center point of the free end of the two connecting arms on the corresponding connecting rod is the same.

[0013] By changing the hook after the connecting rod is replaced with a counterweight, a combination of dumbbells or barbells can be achieved.

[0014] In summary, the present invention has the following beneficial effects: 1. This invention allows for adjustable span by adjusting the height of the bolts and by rotating, moving forward and backward, and synchronously extending and retracting the lead screw, thus adapting to different practical application scenarios. 2. All components of this invention are detachable and can be combined and rearranged in any way to achieve the functional conversion of different training equipment, such as pull-ups, push-ups, dumbbells, barbells, etc. 3. This invention prevents loosening and slippage by setting a limiting bolt; 4. This invention is easy and quick to install and disassemble. Attached Figure Description
