Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, and in particular to a wall-mounted, foldable fitness aid device. Background Technology

[0002] Pull-ups are commonly performed on horizontal bars during fitness exercises. Because beginners often lack upper body strength, they need to use auxiliary equipment to assist with stretching. Using large equipment only allows for kneeling pull-ups, and using resistance bands can easily cause body swaying.

[0003] For example, Chinese utility model patent CN214714005U, with authorization announcement date of November 16, 2021, discloses a pull-up assist exercise device. Specifically, it includes a main frame, a guide section fixedly mounted on the main frame, a bearing seat at the free end of the guide section, and a pedal mounted on the fixed end of each bearing seat on opposite sides. The pedal has two positioning grooves, and two elastic straps are fixedly mounted on the pedal. Positioning blocks are fixedly mounted on both sides of the top of the pedal, and each positioning block has through holes for securing the elastic straps, with the through holes corresponding to the elastic straps. The guide rod of the guide section is fitted with a sliding sleeve and a telescopic spring. When the person performs pull-ups, the telescopic spring pushes the pedal upwards synchronously, providing an upward assist.

[0004] Existing pull-up assist devices are designed with guide rods, pedals, and telescopic springs. The guide rods are connected to the crossbars of the main frame via extension rods and connecting rods. However, the connection between the guide part and the main frame is complex, and the telescopic springs cannot provide a wide range of upward assistance, failing to meet the requirements for wall-mounted installation and flexible storage. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the connection between the guide part and the main frame part of the existing auxiliary exercise device is complicated, the telescopic spring cannot provide a large range of upward assistance, and cannot meet the requirements of wall-mounted installation and flexible storage.

[0006] To address the aforementioned technical problems, this invention provides a wall-mounted, foldable fitness aid device:

[0007] The wall-mounted foldable fitness aid includes a base, two support arms, two guide columns, and an assist rod. The base is provided with a mounting part for fixed connection with the wall. The two support arms are respectively hinged to the base, and a locking element is provided between the support arms and the base.

[0008] Both of the two support arms have through holes at their ends away from the base. The two guide posts are respectively inserted into the through holes of the corresponding support arms. The bottom of the guide posts is also provided with suction cups for adhering and fixing to the ground.

[0009] Each of the two guide posts is equipped with a sliding seat. The side wall of the sliding seat is provided with an insertion hole and a groove communicating with the insertion hole. The end of the assist rod is inserted into the insertion hole of the sliding seat. The end of the assist rod is also provided with a protrusion. The protrusion is in concave-convex fit with the groove and the protrusion is in stop fit with the edge of the insertion hole.

[0010] When the fitness assist device is in the unfolded state, the length direction of the support arm is arranged perpendicular to the wall, the two guide columns are distributed parallel to the wall at intervals, the assist rod is connected to the two sliding seats respectively, and an elastic band is connected between the assist rod and the wall-mounted bar.

[0011] The base is also equipped with a positioning component. When the fitness assist device is in the retracted state, the support arm and the two guide columns are arranged against the wall, and the assist rod can be detachably installed on the positioning component.

[0012] Furthermore, the base includes a strip-shaped base plate and two supports, which are respectively fixedly connected to the ends of the strip-shaped base plate. Two ear plates are provided on the sides of the supports, which are arranged vertically at intervals. A hinge shaft is installed between the two ear plates and the support arm, and the axis of the hinge shaft extends vertically.

[0013] Furthermore, the support is provided with bolt holes, in which expansion bolts for fixed connection with the wall are installed, and the bolt holes constitute the mounting part of the base.

[0014] Furthermore, the ear plate is provided with a first through hole, the end of the support arm is provided with a second through hole, and the locking member is a locking pin, which is inserted into the first through hole and the second through hole.

[0015] Furthermore, the support arm is a telescopic arm, which includes a first arm section and a second arm section. The first arm section and the second arm section are movably inserted into each other. The second arm section is provided with a plurality of adjustment holes at intervals along its length. The first arm section is also equipped with a limiting pin for inserting into the adjustment holes.

[0016] Furthermore, the sliding seat is an L-shaped seat, and the sliding seat has a horizontal section and a vertical section. A linear bearing is fixedly installed on the horizontal section of the sliding seat, and the linear bearing is fitted with the guide post. The vertical section of the sliding seat forms the side wall of the sliding seat.

[0017] Furthermore, the assist rod is a round tube, the insertion hole is a circular hole, the round tube and the circular hole are in clearance fit, the protrusion is a protruding post fixed to the end of the round tube, and the end of the assist rod is also provided with a collar for connecting with the elastic band.

[0018] Furthermore, the lower end of the guide post is welded or threaded to the suction cup, and a rubber buffer pad is provided near the suction cup on the guide post.

[0019] Furthermore, the suction cup is a manual suction cup, which includes a suction cup body, a cover plate and a pressure handle. The cover plate is disposed on the upper side of the suction cup, and the pressure handle is rotatably mounted on the cover plate and connected to the suction cup.

[0020] Furthermore, the length of the assist rod is equal to the length of the strip base plate, and two positioning members are provided symmetrically about the base. The positioning members are L-shaped, and the horizontal sections of the two positioning members are arranged opposite each other for insertion and engagement with the end of the assist rod.

[0021] Compared with existing technologies, the wall-mounted foldable fitness aid of this invention has the following advantages: The wall-mounted foldable fitness aid adopts a design consisting of a base, two support arms, two guide columns, an assist rod, a suction cup, and an elastic band. The base is fixedly connected to the wall via a mounting part, and the two support arms are hinged to the base. Each support arm has a through hole at its end furthest from the base. The two guide columns are inserted into the corresponding through holes of the support arms, and suction cups are provided at the bottom of the guide columns for adhesion to the ground. Furthermore, each guide column is equipped with a sliding seat, and the side wall of the sliding seat has insertion holes and grooves. The end of the assist rod is inserted into the insertion hole of the sliding seat.

[0022] In use, first rotate and unfold the two support arms. The locking mechanism limits the unfolded position of the support arms, ensuring that their length extends outward perpendicular to the wall. Then, insert the two guide posts into the through holes of the support arms. The bottom of the guide posts is fixed to the ground by suction cups. The support arms reliably position the guide posts, ensuring that they remain stable and parallel to the wall when unfolded. Next, align the protrusion of the assist rod with the groove of the sliding seat, allowing the assist rod to smoothly insert into the sliding seat's insertion hole. When the two ends of the assist rod are inserted into the sliding seats of the two guide posts, rotate the assist rod to create a misalignment between the protrusion and the groove. The protrusion engages with the edge of the insertion hole, thus achieving flexible assembly and disassembly of the assist rod and the sliding seat.

[0023] Furthermore, an elastic band connects the assist bar to the wall-mounted horizontal bar. The assist bar is located below the wall-mounted horizontal bar. When the exerciser performs pull-ups, they grip the wall-mounted horizontal bar with their hands and step on the assist bar. The elastic band generates traction assistance along the length of the guide column. Because the vertical position of the guide column is stable and accurate, it ensures that the movement path of the assist bar and its assistance direction are consistent with the direction of the pull-up movement, ensuring a reliable assistance effect for the exerciser.

[0024] To retract the device, first untie the elastic band between the assist rod and the wall-mounted horizontal bar, and remove the assist rod from the holes in the two sliding seats, placing it independently on the positioning piece of the base. Then, detach the suction cup from the ground, releasing the locking mechanism from the support arm's restraint. Rotate the two support arms to move the guide columns closer to the wall until the support arms and both guide columns are flush against the wall, thus completing the folding and storage of the entire fitness aid. The connection between the guide columns and support arms is simple, and the elastic band provides a wider range of upward assistance, meeting the requirements for wall-mounted installation and flexible storage.

[0034] like Figures 1 to 4 As shown, the wall-mounted foldable fitness aid device of this invention includes a base 1, two support arms 2, two guide columns 3, and an assist rod 4. The base 1 is provided with a mounting part 10 for fixed connection with the wall. The two support arms 2 are respectively hinged to the base 1, and a locking member 15 is provided between the support arms 2 and the base 1. The ends of the two support arms 2 away from the base 1 are provided with through holes. The two guide columns 3 are respectively inserted into the through holes of the corresponding support arms 2. The bottom of the guide column 3 is also provided with a suction cup 5, which is used to adhere and fix to the ground.

[0035] Both guide posts 3 are equipped with sliding seats 30. The side wall of the sliding seat 30 is provided with an insertion hole 31 and a groove 32 that connects to the insertion hole 31. The end of the assist rod 4 is inserted into the insertion hole 31 of the sliding seat 30. The end of the assist rod 4 is also provided with a protrusion 41, which is in concave-convex fit with the groove 32. The protrusion 41 is also in stop fit with the edge of the insertion hole 31.

[0036] When the fitness assist device is in the unfolded state, the length direction of the support arm 2 is perpendicular to the wall, the two guide columns 3 are parallel to the wall and spaced apart, the assist rod 4 is connected to the two sliding seats 30 respectively, and the assist rod 4 is connected to the wall-mounted bar 7 by an elastic band 6; the base 1 is also provided with a positioning component 16. When the fitness assist device is in the retracted state, the support arm 2 and the two guide columns 3 are both arranged against the wall, and the assist rod 4 can be detachably installed on the positioning component 16.

[0037] This wall-mounted, foldable fitness aid consists of a base 1, two support arms 2, two guide columns 3, an assist rod 4, a suction cup 5, and an elastic band 6. The base 1 is fixed to the wall via a mounting part 10, and the two support arms 2 are hinged to the base 1. Each support arm 2 has a through hole at its end furthest from the base 1. The two guide columns 3 are inserted into the corresponding through holes of the support arms 2. The bottom of each guide column 3 has a suction cup 5 for attaching to the ground. Furthermore, each guide column 3 has a sliding seat 30, with a hole 31 and a groove 32 on its side wall. The end of the assist rod 4 is inserted into the hole 31 of the sliding seat 30.

[0038] In use, first, rotate and unfold the two support arms 2. The locking piece 15 can limit the unfolded position of the support arms 2, so that the length direction of the support arms 2 extends outward perpendicular to the wall. Then, insert the two guide posts 3 into the through holes of the support arms 2 respectively. The bottom of the guide posts 3 is attached to the ground by suction cups 5. The support arms 2 play a reliable positioning role for the guide posts 3, ensuring that the two guide posts 3 remain stable in a vertically extended state parallel to the wall when unfolded. Then, align the protrusion 41 of the assist rod 4 with the groove 32 of the sliding seat 30, so that the assist rod 4 can be smoothly inserted into the insertion hole 31 of the sliding seat 30. When the two ends of the assist rod 4 are respectively inserted into the sliding seat 30 of the two guide posts 3, rotate the assist rod 4 to make the protrusion 41 and the groove 32 misaligned. The protrusion 41 and the edge of the insertion hole 31 stop and cooperate, thereby realizing the flexible assembly and disassembly of the assist rod 4 and the sliding seat 30.

[0039] Furthermore, an elastic band 6 connects the assist bar 4 to the wall-mounted horizontal bar 7. The assist bar 4 is located below the wall-mounted horizontal bar 7. When the exerciser performs pull-ups, he grips the wall-mounted horizontal bar 7 with his hands and steps on the assist bar 4. The elastic band 6 generates traction assistance along the length of the guide column 3. Since the vertical position of the guide column 3 is stable and accurate, it ensures that the movement path of the assist bar 4 and its assistance direction are consistent with the direction of the pull-up movement, ensuring a reliable assistance effect for the exerciser.

[0040] To retract the device, first disconnect the elastic band 6 between the assist rod 4 and the wall-mounted horizontal bar 7, and remove the assist rod 4 from the insertion holes 31 of the two sliding seats 30, placing the assist rod 4 alone on the positioning piece 16 of the base 1. Then, separate the suction cup 5 from the ground, releasing the locking piece 15 from the limiting action of the support arm 2. Rotate the two support arms 2 to move the guide column 3 towards the wall until the support arm 2 and the two guide columns 3 are both against the wall, thus completing the folding and storage operation of the entire fitness aid device. The connection between the guide column 3 and the support arm 2 is simple, and the elastic band 6 provides a wider range of upward assistance, meeting the requirements of wall-mounted installation and flexible storage.

[0041] In this embodiment, the base 1 includes a strip-shaped base plate 11 and two supports 12. The two supports 12 are respectively fixedly connected to the ends of the strip-shaped base plate 11. Two ear plates 13 are provided on the side of the supports 12, and the two ear plates 13 are arranged vertically at intervals. A hinge shaft 14 is installed between the two ear plates 13 and the support arms 2. The axis of the hinge shaft 14 extends vertically, and the two support arms 2 can be rotated to unfold or retract around the vertical axis. Furthermore, bolt holes are provided on the supports 12, and expansion bolts for fixed connection with the wall are installed in the bolt holes. The bolt holes constitute the mounting part 10 of the base 1. By inserting expansion bolts into the bolt holes of the supports 12, the base 1 is reliably fixed to the wall, thus fulfilling the usage requirements of wall-mounted installation of the fitness assistive device.

[0042] As a further preferred embodiment, the ear plate 13 is also provided with a first through hole, and the end of the support arm 2 is provided with a second through hole. The locking member 15 is a locking pin, which is inserted into the first and second through holes. When unfolded, the second through hole of the support arm 2 is aligned with the first through hole of the ear plate 13, and the locking member 15 can be used to limit the support arm 2 to a cantilevered state perpendicular to the wall; when it needs to be retracted, the locking member 15 can be removed to allow the support arm 2 to be rotated smoothly.

[0043] The support arm 2 is a telescopic arm, comprising a first arm section 21 and a second arm section 22. The first arm section 21 and the second arm section 22 are movably inserted into each other. The second arm section 22 has multiple adjustment holes 24 spaced apart along its length. The first arm section 21 is also equipped with a limiting pin 23 for inserting into the adjustment holes 24. The support arm 2 adopts a telescopic arm structure design, which allows for flexible adjustment of the cantilever length of the support arm 2 according to different wall distances, thus improving its versatility.

[0044] In this embodiment, the sliding seat 30 is an L-shaped seat with a horizontal section and a vertical section. A linear bearing 33 is fixedly installed on the horizontal section of the sliding seat 30, and the linear bearing 33 is fitted with the guide post 3. The vertical section of the sliding seat 30 forms the side wall of the sliding seat 30. The sliding fit between the linear bearing 33 and the guide post 3 has high precision, which can ensure the smoothness and accuracy of the up-and-down movement of the assist rod 4.

[0045] As a further preferred option, the assist rod 4 is a round tube, the insertion hole 31 is a round hole, the round tube and the round hole are clearance fit, the protrusion 41 is a protruding post fixed to the end of the round tube, and the end of the assist rod 4 is also provided with a collar 42 for connecting with the elastic band 6. By connecting the collar 42 with the hook of the elastic band 6, the purpose of quick assembly and disassembly between the elastic band 6 and the assist rod 4 can be achieved.

[0046] In addition, the lower end of the guide post 3 is welded or threaded to the suction cup 5. A rubber buffer pad 34 is also provided near the suction cup 5 on the guide post 3. The rubber buffer pad 34 is designed to prevent the sliding seat 30 from colliding and damaging the suction cup 5 when it moves to the lower end of the guide post 3, thus improving the service life of the auxiliary device. Specifically, the suction cup 5 is a manual suction cup 5, which includes a suction cup body 51, a cover plate 52, and a pressure handle 53. The cover plate 52 is located on the upper side of the suction cup 5, and the pressure handle 53 is rotatably mounted on the cover plate 52 and connected to the suction cup 5. Lifting the pressure handle 53 seals the suction cup body 51 against the ground. Then, rotating the pressure handle 53 downwards creates a negative pressure suction between the suction cup body 51 and the ground, thereby achieving the function of adsorption and fixation.

[0047] It should be noted that the length of the assist rod 4 is equal to the length of the strip base plate 11. Two positioning members 16 are provided symmetrically about the base 1. The positioning members 16 are L-shaped, and the horizontal sections of the two positioning members 16 are arranged opposite each other to engage with the ends of the assist rod 4. When retracting, one end of the assist rod 4 can be inserted into the horizontal section of one positioning member 16 first. After one end is fully inserted, the other end of the assist rod 4 can be inserted into the horizontal section of the other positioning member 16. Finally, the assist rod 4 can be moved so that both ends are supported by the positioning members 16.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
