Description

Technical Field

[0001] This invention relates to sports equipment, and more particularly to a multi-directionally adjustable parallel bar. Background Technology

[0002] Parallel bars are a commonly used sports equipment in gymnastics training, physical education, and fitness rehabilitation. They typically consist of two sets of uprights arranged symmetrically on either side, and horizontal bars extending from the uprights. The two bars are parallel to each other and at the same height. Users use their hands to support themselves on the bars to perform movements such as swinging, jumping, twisting, and static support, in order to train the strength and coordination of the upper limbs, shoulders, back, and abdominal muscles.

[0003] Currently, most parallel bars fall into two categories: fixed and adjustable. Fixed bars have a rigid connection between the uprights and the horizontal bars, and neither the height of the uprights nor the distance between the two horizontal bars can be adjusted. Due to their welded structure, they have high overall strength and good torsional resistance. Adjustable bars, on the other hand, have several positioning holes on the uprights or horizontal bars, and the installation height of the uprights can be changed by using pins. This improves the adaptability of the parallel bars to some extent, but it requires hollowing out the inside of the bars, which reduces their strength. If a heavy user makes a large movement, the adjustable section of the uprights may twist or deform, causing the user to fall from the parallel bars, which can easily lead to a safety accident.

[0004] Therefore, the purpose of this invention is to provide a multi-directionally adjustable parallel bar that can adjust the length of the uprights, the horizontal bars, and the distance between the horizontal bars, and can protect the adjusted position of the uprights, so that the parallel bars can be adapted to people of more body types and weights, thereby improving the safety of the parallel bars during use. Summary of the Invention

[0005] This invention provides a multi-directionally adjustable double bar, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows: A multi-directional adjustable parallel bar, comprising: An adjustable crossbar includes a main support rod, with crossbar adjustment sections slidably sleeved at both ends of the main support rod. The crossbar adjustment sections are adjusted to overlap with the main support rod by crossbar adjustment components. An adjustable column includes a column adjustment section disposed at the lower end of a crossbar adjustment section, wherein a column is movably fitted at the lower end of the column adjustment section, and the column is adjusted to overlap the column adjustment section via a column adjustment component. A downward distance adjustment structure is installed between two columns to adjust the distance between the two columns; A pole support assembly includes a support cylinder slidably mounted on the outside of a column. Several support members are movably mounted on the upper half of the inner wall of the support cylinder. When the support cylinder is located in the area of ​​the column, the outer arc surface of the support member is flush with the inner wall of the support cylinder and the support member abuts against the outside of the column. When the support cylinder is located in the area of ​​the column adjustment section and the column, the support member pops out and abuts against the outer wall of the column adjustment section, and the top of the support cylinder abuts against the lower end of the crossbar adjustment section. A rod lifting assembly connected to the lower adjustment structure includes a pad plate connected to the lower adjustment structure. The top of the pad plate is provided with a movable part connected to the bottom of the support cylinder. When the movable part moves upward, it drives the support cylinder to move upward so that the support cylinder abuts against the lower end of the crossbar adjustment section. When the movable part moves downward, it drives the support cylinder to move below the column adjustment section.

[0007] As a further improvement, the main support rod is provided with several horizontal adjustment holes on the side near the horizontal adjustment section, and the horizontal adjustment section is provided with a corresponding horizontal hole.

[0008] As a further improvement, the column adjustment section has several vertical adjustment holes on the side near the column, and the column has a vertical corresponding hole corresponding to the vertical adjustment holes.

[0009] As a further improvement, both the crossbar adjusting component and the column adjusting component are threaded knobs.

[0010] As a further improvement, the column is an L-shaped structure, and the downward adjustment structure includes an inner connecting seat sleeved on one end of the short axis of the column on the same side, with two inner connecting seats spaced apart, and a lateral adjustment component connected to the column is provided on the inner side of the inner connecting seat.

[0011] As a further improvement, the support cylinder includes a solid section that is slidably sleeved on the outside of the column. The upper end of the solid section is integrally formed with an inwardly recessed section. The support member is disposed inside the inwardly recessed section, and a clearance groove corresponding to the vertical adjustment hole is opened on the outside of the inwardly recessed section.

[0012] As a further improvement, the support includes several guide cylinders fixed in the retracted section, and telescopic springs are installed in the guide cylinders. All the telescopic springs are connected to a support plate on the side away from the inner wall of the retracted section. The bottom surface of the support plate is inclined. When the support plate contacts the upper edge of the column, the support plate retracts into the retracted section.

[0013] As a further improvement, the upper and lower ends of the support plate are always in contact with the upper and lower ends of the inner wall of the recessed section.

[0014] As a further improvement, the movable component includes at least two sets of hydraulic cylinders disposed on the raised plate, with a standing frame mounted on the top of the hydraulic cylinders via an outer extension plate, and the two sides of the standing frame extending and fixed to the bottom of the support cylinder.

[0015] As a further improvement, the bottom of the support cylinder is integrally formed with a lower sliding ring, and the standing frame includes a standing plate connected to a hydraulic cylinder. Extension plates are connected to both sides of the standing plate, and the extension plates are fixed to the lower sliding ring.

[0016] The beneficial effects of this invention are: Compared to existing height adjustment methods, this invention features a three-section adjustable structure. First, an adjustable crossbar provides primary support strength via a main support bar, and the length of the crossbar becomes adjustable by changing the relative position of the adjustable section of the crossbar with respect to the main support bar. Second, an adjustable upright allows for adjustable height by changing the relative position of the adjustable section of the upright with respect to the upright. Third, a downward adjustment structure allows for adjustable width between the two uprights by changing the relative distance between them. This three-section adjustment system allows the parallel bars to be adapted to users of various ages, body types, and purposes, making the parallel bars more versatile.

[0017] Existing parallel bars, due to their adjustability, are prone to becoming weak points in the adjustable positions, easily deforming when used with a wide grip or by heavier users. Therefore, this invention addresses this issue by incorporating a bar support assembly. This assembly features a sliding support cylinder on the outer side of the upright, allowing for sliding support based on the relative position of the adjustable section and the upright. Furthermore, during the support phase of the horizontal bar adjustment section, an inner support component pops out, abutting against the outer side of the adjusted section, thus enhancing the strength of the reduced-thickness adjusted section. By supporting the bottom of the horizontal bar adjustment section and increasing the thickness of the adjusted section, the entire adjustable upright maintains sufficient strength even after adjustment, thereby improving user safety during training.

[0018] Since the relative position between the column adjustment section and the column needs to change according to the user's needs, the support cylinder cannot be set in a fixed manner. Therefore, this invention uses a rod lifting assembly with a movable part at the lower end of the support cylinder. During the adjustment phase between the column adjustment section and the column, the support cylinder slides down. After the adjustment process is completed, the movable part drives the support cylinder to rise and abut against the bottom of the crossbar adjustment section. Thus, it can achieve a stable support and fixation effect regardless of the height of the column, improving the practicality of this invention. Attached Figure Description

[0029] Reference Figures 1-6 As shown, a multi-directional adjustable parallel bar includes: an adjustable crossbar 1, comprising a supporting main bar 11, with crossbar adjustment sections 12 slidably sleeved at both ends of the supporting main bar 11, the crossbar adjustment sections 12 being adjusted to overlap with the supporting main bar 11 via crossbar adjustment components 13; an adjustable column 2, comprising a column adjustment section 21 disposed at the lower end of the crossbar adjustment section 12, the lower end of the column adjustment section 21 being movably fitted with a column 22, the column 22 being adjusted to overlap with the column adjustment section 21 via a column adjustment component 23; a downward adjustment structure 3, disposed between the two columns 22, used to adjust the distance between the two columns 22; and a bar support assembly 4, comprising a support cylinder 41 slidably mounted on the outside of the column 22, the upper half of the inner wall of the support cylinder 41 being movably mounted with several support components 42, when the support cylinder 41 is positioned at the top of the column 22, the support cylinder 41 is adjusted to overlap with the column adjustment section 21 via a column adjustment component 23; a downward adjustment structure 3, disposed between the two columns 22, used to adjust the distance between the two columns 22; and a bar support assembly 4, comprising a support cylinder 41 slidably mounted on the outside of the column 22, the upper half of the inner wall of the support cylinder 41 being movably mounted with several support components 42, the support cylinder 41 being adjusted to overlap with the column 22; and a bar support assembly 4, comprising a support cylinder 41 slidably mounted on the outside of the column 22, the support cylinder 41 being slidably mounted on the upper half of the inner wall of the support cylinder 22, the support cylinder 41 being adjusted to overlap with the column 22; and a bar support assembly 4, comprising a support cylinder 41 slidably mounted on the upper half of the inner wall of the support cylinder 2 When the column 22 is in the region, the outer arc surface of the support member 42 is flush with the inner wall of the support cylinder 41 and the support member 42 abuts against the outer side of the column 22. When the support cylinder 41 is in the region of the column adjustment section 21 and the column 22, the support member 42 pops out and abuts against the outer wall of the column adjustment section 21, and the top of the support cylinder 41 abuts against the lower end of the crossbar adjustment section 12. The rod lifting assembly 5 is connected to the lower adjustment structure 3. The rod lifting assembly 5 includes a pad plate 51 connected to the lower adjustment structure 3. The top of the pad plate 51 is provided with a movable member 52 that is connected to the bottom of the support cylinder 41. When the movable member 52 moves upward, it drives the support cylinder 41 to move upward so that the support cylinder 41 abuts against the lower end of the crossbar adjustment section 12. When the movable member 52 moves downward, it drives the support cylinder 41 so that the support cylinder 41 is lower than the column adjustment section 21.

[0030] This embodiment uses an adjustable structure. Compared to existing height adjustment methods, this embodiment has three adjustable sections. First, the adjustable crossbar 1 provides the main support strength of the crossbar through the main support bar 11, and the length of the crossbar becomes adjustable by changing the relative position of the crossbar adjustment section 12 and the main support bar 11. Second, the adjustable uprights 2 allow the relative position of the upright adjustment section 21 and the uprights 22 to change, making the height of the uprights adjustable. Third, the downward adjustment structure 3 allows the relative distance between the two uprights 22 to change, thus making the width between the uprights 22 adjustable. Through these three adjustable sections, the parallel bars can be adapted to users of various ages, body types, and purposes, making the parallel bars more adaptable.

[0031] In the adjustable crossbar 1 section, the main support rod 11 has several horizontal adjustment holes 121 on the side near the crossbar adjustment section 12, and the crossbar adjustment section 12 has a corresponding horizontal hole 122. In order to improve the strength of the mating position between the main support rod 11 and the crossbar adjustment section 12 and to prevent the section from denting when subjected to force, this embodiment also provides a short sleeve at this position to bear the pressure and prevent deformation or denting from occurring at this position.

[0032] In the adjustable column 2, the column adjustment section 21 is provided with a plurality of vertical adjustment holes 211 on the side near the column 22, and the column 22 is provided with a vertical corresponding hole 212 corresponding to the vertical adjustment holes 211. By setting multiple vertical adjustment holes 211, the column adjustment section 21 can be inserted into or extended into the column 22.

[0033] In this embodiment, both the crossbar adjustment component 13 and the column adjustment component 23 are threaded knobs. In fact, other limiting structures can be used to avoid restricting the user's use.

[0034] In this embodiment, the crossbar adjustment member 13 is located at the lower end of the crossbar adjustment section 12, thereby preventing the user from touching the adjustment member over a large area.

[0035] In the lower adjustment structure 3, the column 22 is an L-shaped structure. The lower adjustment structure 3 includes an inner connecting seat 31 sleeved on one end of the short axis of the column 22 on the same side. The two inner connecting seats 31 are spaced apart. The inner side of the inner connecting seat 31 is provided with a lateral adjustment member 33 that connects to the column 22. In this embodiment, the lateral adjustment member 33 is also adjusted by the cooperation of a knob and a mating hole to adjust the short axis of the column 22. In other embodiments, a solid steel pipe or plastic pipe can be used to adjust the column by cooperating with a hydraulic cylinder. A soft pad or other protective structure can be laid between the two inner connecting seats 31.

[0036] Existing parallel bars, due to their adjustability, are prone to becoming weak points in the adjustable positions, easily deforming when used with a wide grip or by heavier users. Therefore, this embodiment uses a bar support assembly 4, with a sliding support cylinder 41 on the outside of the upright 22, to provide sliding support according to the relative position of the upright adjustment section 21 and the upright 22. Furthermore, during the support phase of the horizontal bar adjustment section 12, the inner support member 42 can be ejected, allowing the support member 42 to abut against the outside of the upright adjustment section 21, enhancing the strength of the reduced-thickness upright adjustment section 21. By supporting the bottom of the horizontal bar adjustment section 12 and increasing the thickness of the upright adjustment section 21, the entire adjustable upright 2 maintains sufficient strength even after adjustment, thereby improving the user's safety during training.

[0037] The support cylinder 41 is designed not only to assist the column adjustment section 21 in supporting the adjustable crossbar 1, but also to make way for the column adjustment component 23. Therefore, the support cylinder 41 in this embodiment includes a solid section 411 that is slidably sleeved on the outside of the column 22. The upper end of the solid section 411 is integrally formed with an inward section 412. The support component 42 is disposed in the inward section 412. The outer side of the inward section 412 is provided with a clearance groove 413 corresponding to the vertical adjustment hole 211. By supporting the adjustable crossbar 1 through the inward section 412 and the support component 42, the same stable support effect as the fixed sleeve can be achieved.

[0038] The support member 42 has two working states. Specifically, the support member 42 includes several guide cylinders 421 fixed in the inner retraction section 412. A telescopic spring 422 is installed in the guide cylinder 421. A support plate 423 is connected to the side of the telescopic spring 422 away from the inner wall of the inner retraction section 412. The bottom surface of the support plate 423 is inclined. When the support plate 423 contacts the upper edge of the column 22, the support plate 423 retracts into the inner retraction section 412. When the support plate 423 retracts, the telescopic spring 422 will be completely retracted into the guide cylinder 421 and limited by it to avoid deformation. At the same time, the inclined surface of the bottom surface of the support plate 423 and the cooperation of the telescopic spring 422 can realize adaptive expansion and contraction.

[0039] In order to make the effect of the recessed section 412 + support member 42 the same as that of the fixed sleeve, the upper and lower ends of the support plate 423 in this embodiment are always in contact with the upper and lower ends of the inner wall of the recessed section 412, so as to achieve the effect of supporting the entire section.

[0040] Since the relative positions of the column adjustment section 21 and the column 22 need to be changed according to the user's needs, the support cylinder 41 cannot be set in a fixed manner. Therefore, in this embodiment, the rod lifting assembly 5 is provided, and the movable part 52 is provided at the lower end of the support cylinder 41. During the adjustment phase of the column adjustment section 21 and the column 22, the support cylinder 41 is lowered. After the adjustment process is completed, the movable part 52 drives the support cylinder 41 to rise and abut against the lower part of the crossbar adjustment section 12. Thus, a stable support and fixing effect can be achieved regardless of the height of the column, improving the practicality of the present invention.

[0041] Since the movable component 52 needs to provide power for the lifting and lowering of the support cylinder 41, the movable component 52 in this embodiment includes at least two sets of hydraulic cylinders 522 disposed on the raised plate 51. The top of the hydraulic cylinder 522 is equipped with a standing frame 521 through an outer extension plate. The two sides of the standing frame 521 extend and are fixed to the bottom of the support cylinder 41. The support cylinder 41 can be adjusted to a suitable height through the standing frame 521 via the hydraulic cylinder 522. Since the hydraulic cylinder 522 has good support, even if the user stands on the standing frame 521 and climbs onto the parallel bars, it will not have any impact on the hydraulic cylinder 522.

[0042] In order to enable the support cylinder 41 and the standing frame 521 to move up and down synchronously, the bottom of the support cylinder 41 in this embodiment is integrally formed with a lower sliding ring 414. The standing frame 521 includes a standing plate 5211 connected to a hydraulic cylinder 522. Extension plates 5212 are connected to both sides of the standing plate 5211. The extension plates 5212 are fixed to the lower sliding ring 414. The lower sliding ring 414 is raised and lowered by the extension plates 5212, thereby realizing the position change of the support cylinder 41. Thus, the support cylinder 41 can also be adjusted synchronously when the adjustable column 2 is raised.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
