Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a support member for an abdominal wheel and an abdominal wheel. Background Art

[0002] An abdominal wheel is a small pushing exercise equipment used for exercising muscles, joints and reducing weight. It is easy to operate and has little requirement for the site, and is suitable for people of all ages.

[0003] Currently, in addition to the abdominal wheel with straight handles on both sides of the wheel body, there is also an abdominal wheel with support plates on both sides of the wheel body as recorded in the patent document with the Chinese patent publication number CN308035918S on the market; when a user uses such an abdominal wheel, the user needs to lean the arms on the support plates on both sides of the wheel body and hold the holding members at the front ends of the support plates with the hands, and exercise in the posture of leaning the upper limbs on the support plates.

[0004] This type of abdominal wheel changes the posture of the user's body and the distribution of weight during exercise, and is more suitable for novice users;

[0005] However, when exercising in the posture of leaning the upper limbs on the support plates, if a single wheel body is used, there will be a problem of instability during the forward and backward pushing and pulling of the abdominal wheel, and it may even cause the user to be injured due to falling; therefore, all existing such abdominal wheels, like the above-mentioned cited patent document, use two side-by-side wheel bodies for forward and backward sliding to ensure the stability during the forward and backward pushing and pulling of the abdominal wheel. However, setting two wheel bodies for the abdominal wheel not only increases the production cost, but also makes the packaging volume of the abdominal wheel too large; therefore, it is necessary to propose a support member that can maintain stability during the forward and backward pushing and pulling when used on a single-wheel abdominal wheel and an abdominal wheel using this support member. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a technical solution for a support member for an abdominal wheel and an abdominal wheel aiming at the deficiencies of the prior art. The abdominal wheel using a single wheel body has lower cost and smaller packaging volume compared with using two wheel bodies; the support member can also maintain stability during the forward and backward pushing and pulling when used on a single-wheel abdominal wheel.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0055] Embodiment 1

[0056] A support member 10 used on both sides of an abdominal wheel for a user's upper limbs to lean on for the push-pull movement of the abdominal wheel. Its connection state with the abdominal wheel is as Figure 1 shown;

[0057] The support member 10 is fixed relative to the central tube 2 of the abdominal wheel;

[0058] By connecting the support member 10 to both sides of the wheel body 1 of the abdominal wheel, as Figure 1 shown, when the user uses the abdominal wheel, the arm can lean on the support member 10, changing the body posture and weight distribution during exercise, and being more suitable for novice users.

[0059] In order to solve the problems that the double-wheel abdominal wheel has a higher production cost and a larger packaging volume, the support member 10 can be used for a single-wheel abdominal wheel;

[0060] The support member 10 includes a support plate 75 for supporting the user's arm on both sides of the wheel body 1 of the abdominal wheel, as Figure 2 、 Figure 4 shown;

[0061] A sliding assistance structure 9 is provided at the bottom of the support plate 75, as Figure 1 、 Figure 2 shown;

[0062] The sliding auxiliary structure 9 can form a support between the support plate 75 and the ground. Thus, for the ab wheel with a single wheel body 1, the sliding auxiliary structures 9 at the bottoms of the support plates 75 on both sides of the wheel body 1 can play a stabilizing role in the process of pushing and pulling the ab wheel back and forth, enabling the ab wheel to maintain balance.

[0063] In this embodiment, the sliding auxiliary structure 9 is arranged at the rear end of the support plate 75, that is, the end close to the user when the user uses the ab wheel, as Figure 1 shown;

[0064] The sliding auxiliary structure 9 includes a support frame 91, and the support frame 91 is used to form a support between the support plate 75 and the ground;

[0065] A second included angle 92 is formed between the support frame 91 and the support plate 75, as Figure 2 shown;

[0066] In this embodiment, the second included angle 92 is set to 25°; the support frame 91 set at this angle can maintain the best support with the ground during the process of pushing and pulling the ab wheel back and forth, ensuring the stable sliding of the ab wheel.

[0067] The sliding auxiliary structure 9 includes a roller 93, and the roller 93 is rotatably connected to one end of the support frame 91, as Figure 1 、 Figure 2 shown;

[0068] The roller 93 is used to contact the ground to realize rolling. The sliding auxiliary structure 9 is provided with the roller 93 in contact with the ground, which can ensure the support with the ground without affecting the sliding of the ab wheel.

[0069] The sliding auxiliary structure 9 is provided with a third assembly bolt 94, and the sliding auxiliary structure 9 is detachably connected to the support plate 75 through the third assembly bolt 94;

[0070] Specifically, corresponding bolt holes corresponding to the third assembly bolt 94 are provided at the corresponding positions at the bottom of the support plate 75, as Figure 7 shown;

[0071] There are corresponding bolt mounting holes at the top end of the support frame 91. The third assembly bolt 94 can pass through the bolt mounting holes and be tightened with the bolt holes at the bottom of the support plate 75 to achieve assembly, as Figure 8 shown;

[0072] By setting the sliding auxiliary structure 9 and the support plate 75 as separate bodies, the product can choose a smaller packaging volume when being packaged.

[0073] The front end of the support plate 75 is connected with a holding part 8, as Figure 1 、 Figure 2 shown; The holding part 8 is used for the user to grip;

[0074] A first included angle 81 is formed between the holding portion 8 and the support plate 75, as Figure 2 shown;

[0075] In this embodiment, the first included angle 81 is set to 160 degrees; with this angle setting, when the user's arm is placed on the surface of the support plate 75, the palm can achieve a ergonomic grip on the holding portion 8.

[0076] The holding portion 8 and the support plate 75 are detachably connected; in this way, the purpose of reducing the product packaging volume can be achieved;

[0077] In this embodiment, an installation groove 83 is provided at the front end of the support plate 75, as Figure 7 shown; one end of the holding portion 8 for connecting with the support plate 75 is provided with an installation block 84 adapted to the installation groove 83, as Figure 5 、 Figure 6 shown;

[0078] An installation post 85 is formed in the installation groove 83, and the installation post 85 is in a convex shape, as Figure 7 shown;

[0079] A bolt hole adapted to the second assembly bolt is formed in the vertical direction of the installation post 85, as Figure 7 shown;

[0080] A first limiting plate 861 and a second limiting plate 862 are formed on the upper surface of the installation block 84, as Figure 5 、 Figure 6 shown, and a first limiting groove 86 adapted to the installation post 85 is formed between the first limiting plate 861 and the second limiting plate 862;

[0081] When the holding portion 8 is installed at the front end of the support plate 75, the installation block 84 needs to be sleeved in the installation groove 83 in a matching manner, as Figure 8 shown; at this time, the first limiting groove 86 will be engaged with the installation post 85 to form a horizontal limit between the holding portion 8 and the support plate 75; the second assembly bolt can pass through the hole at the bottom of the installation block 84 and be tightened in cooperation with the bolt hole in the vertical direction of the installation post 85 to achieve vertical locking between the holding portion 8 and the support plate 75;

[0082] The installation block 84 is sleeved in the installation groove 83 in a matching manner, and one end of the installation block 84 on the holding portion 8 is integrally formed therewith. By the installation block 84 being sleeved in the installation groove 83 over a certain length, the effect of improving the connection stability between the holding portion 8 and the support plate 75 is achieved.

[0083] In this embodiment, a limiting flange 87 is formed at the front edge of the installation groove 83, as Figure 7 shown;

[0084] In this embodiment, the limiting flange 87 is a C-shaped flange structure with an opening facing downward, as Figure 7 shown;

[0085] A second limiting groove 88 adapted to the limiting flange 87 is formed between the upper surface of the holding portion 8 and the second limiting plate 862, as Figure 5 , Figure 6 shown;

[0086] When the mounting block 84 is fitted and sleeved in the mounting groove 83, the limiting flange 87 will be fitted and embedded in the second limiting groove 88, as Figure 8 shown, so that the horizontal direction limiting between the holding portion 8 and the support plate 75 can be further realized.

[0087] The support plate 75 forms an extension portion 76 on the side away from the wheel body 1, as Figure 1 , Figure 4 shown;

[0088] The extension portion 76 is integrally formed on the support plate 75, which makes the surface of the support plate 75 wider, so that the support plate 75 has a larger surface area for the user's arm to lean on, and the user can flexibly select the specific landing point of the arm on the upper surface of the support plate 75 according to actual needs;

[0089] The surface of the support plate 75 forms a first cushion body 77, as Figure 4 shown;

[0090] The first cushion body 77 is made of a flexible material, which can form a flexible contact surface on the surface of the support plate 75, so that the support plate 75 can provide a softer support for the user.

[0091] The upper surface of the holding portion 8 forms a second cushion body 82, as Figure 4 shown;

[0092] The second cushion body 82 can form a flexible contact surface on the surface of the holding portion 8.

[0093] The support member 10 is provided with a mounting structure, and the support member 10 is detachably connected to the central tube 2 through the mounting structure;

[0094] An abdominal wheel includes a wheel body 1 and a central tube 2 movably passing through the wheel body 1. The support member 10 is arranged on both sides of the wheel body 1 through connection with the central tube 2, as Figure 3 shown;

[0095] In this embodiment, the mounting structure includes a connecting tube 78 formed at the bottom of the support plate 75, as Figure 7 , Figure 8 shown;

[0096] The central tube 2 can be sleeved inside the connecting tube 78, as Figure 4 shown;

[0097] On one side of the connecting tube 78, a first assembly bolt 79 is movably arranged, as Figure 8 shown;

[0098] When the central tube 2 is movably sleeved inside the connecting tube 78, by inserting the first assembly bolt 79 into the connecting tube 78 from one side and tightening it in cooperation with the screw hole of the central tube 2, the fixing of the support member 10 relative to the central tube 2 can be realized;

[0099] The support member 10 is detachably connected to the central tube 2 through the first assembly bolt 79, realizing the separation of the support member 10 from the ab wheel, and the volume of product packaging can be reduced.

[0100] The ab wheel applied with this support member 10 is a damping adjustable ab wheel;

[0101] In this embodiment, an electronic component 12 for counting is arranged on the outer side surface of the wheel body 1, as Figure 1 shown; The electronic component 12 is installed on the outer side of the wheel body 1 through an electronic component installation groove.

[0102] The central tube 2 movably penetrates through the wheel body 1 so that the wheel body 1 can rotate around the central tube 2;

[0103] More than two damping mechanisms 4 for forming resistance in the rotation direction between the wheel body 1 and the central tube 2 are arranged between the wheel body 1 and the central tube 2;

[0104] In this embodiment, taking the case where two damping mechanisms 4 are arranged between the wheel body 1 and the central tube 2 as an example for expansion, this is only a preferred embodiment, and the damping mechanism 4 can also be three or more.

[0105] The damping mechanism 4 is fixed relative to the inner side wall of the wheel body 1;

[0106] A sliding clutch part 3 is arranged on the central tube 2, as Figure 9 shown; The sliding clutch part 3 is radially locked relative to the central tube 2 and can axially displace along the central tube 2;

[0107] By axially displacing on the central tube 2, the sliding clutch part 3 can be locked in cooperation with the inner ring of one or two damping mechanisms 4, so as to realize the radial locking of the damping mechanism 4 relative to the central tube 2.

[0108] The sliding clutch part 3 is provided with an elastic part for driving it to displace towards the damping mechanism 4;

[0109] In this embodiment, the elastic part is a spring 31, as Figure 11 shown;

[0110] The sliding clutch member 3 is provided with a clutch member base 21, and the clutch member base 21 is fixed to the central tube 2;

[0111] The sliding clutch member 3 is slidably sleeved in the clutch member base 21. As Figure 9 shown, an axial limiting component is provided between the clutch member base 21 and the sliding clutch member 3 to realize the radial locking of the sliding clutch member 3 relative to the central tube 2;

[0112] In this embodiment, the axial limiting component between the clutch member base 21 and the sliding clutch member 3 includes a limiting chute 22 formed on the inner side wall of the clutch member base 21. As Figure 12 shown;

[0113] A first limiting strip 34 is formed on the outer side surface of the sliding clutch member 3. As Figure 11 、 Figure 13 shown;

[0114] For the part of the sliding clutch member 3 located in the clutch member base 21, the radial locking of the sliding clutch member 3 relative to the clutch member base 21 is realized by the cooperation and insertion of the first limiting strip 34 and the limiting chute 22;

[0115] In this embodiment, a screw hole is opened at one end of the clutch member base 21; by tightening the screw passing through the screw hole in cooperation with the central tube 2, the fixation of the clutch member base 21 and the central tube 2 can be realized;

[0116] A spring 31 is arranged in the clutch member base 21, one end of which abuts against the inner wall of the clutch member base 21, and the other end abuts against the sliding clutch member 3;

[0117] In this way, the spring 31 acts between the sliding clutch member 3 and the central tube 2. During the process that the sliding clutch member 3 retracts into the clutch member base 21, the spring 31 is compressed;

[0118] The driving force generated by the spring 31 stretching and rebounding can push the sliding clutch member 3 to extend from the clutch member base 21, that is, drive the sliding clutch member 3 to displace in the direction of the damping mechanism 4.

[0119] The damping mechanism 4 includes a spring box 42 and a spiral spring 41 sleeved on the spring box 42. As Figure 10 shown;

[0120] One end of the spiral spring 41 is formed with a clamping member 43, and a clamping groove 44 adapted to the clamping member 43 is formed on the inner side of the spring box 42. The outer ring of the spiral spring 41 is fixed to the spring box 42 through the cooperation of the clamping member 43 and the clamping groove 44;

[0121] A fixing hole 45 is provided on the outer side wall of the spring box 42. As Figure 10 shown;

[0122] The mainspring barrel 42 is fixedly connected to the inner side wall of the wheel body 1 through the fixing holes 45;

[0123] A keyway structure 35 is provided at the center of the mainspring barrel 42, and the inner ring of the spiral spring 41 is connected to the keyway structure 35, as Figure 10 shown;

[0124] After the sliding clutch member 3 extends from the clutch member base 21 under the drive of the spring 31, the first limiting strip 34 on its outer side wall can be inserted into the keyway structure 35 in a matching manner;

[0125] Through the matching insertion of the first limiting strip 34 and the keyway structure 35, the cooperation and locking between the sliding clutch member 3 and the damping mechanism 4 can be achieved;

[0126] After the sliding clutch member 3 is locked in cooperation with the damping mechanism 4, since the sliding clutch member 3 is radially locked relative to the central tube 2, the damping mechanism 4 takes effect between the wheel body 1 and the central tube 2 to form a resistance in the rotational direction.

[0127] The sliding clutch member 3 is provided with a multi-stage limiting member 5, and the multi-stage limiting member 5 is used to limit the displacement distance of the sliding clutch member 3 driven in multiple stages. The sliding clutch member 3 can be locked in cooperation with one or more damping mechanisms 4 under the simultaneous opposite action of the elastic member and the multi-stage limiting member 3.

[0128] Specifically, the multi-stage limiting member 5 is located on one side of the damping mechanism 4 and is the side relative to the elastic member, as Figure 9 shown;

[0129] The multi-stage limiting member 5 is used to limit the displacement distance of the sliding clutch member 3 in the driving direction of the elastic member. By limiting the displacement distance, the cooperation between the sliding clutch member 3 and the corresponding number of damping mechanisms 4 is achieved, and the selection of the resistance gear is realized.

[0130] In this embodiment, the multi-stage limiting member 5 is provided with a slope-type limiting structure 51, and the slope-type limiting structure 51 is a tubular structure with a slope surface, as Figure 13 、 Figure 14 shown;

[0131] The slope surface of the slope-type limiting structure 51 abuts against the sliding clutch member 3 in a matching manner, as Figure 13 shown;

[0132] By changing the position where the sliding clutch member 3 abuts against the slope surface, under the action of the height difference of the slope surface, the limiting distance of the multi-stage limiting member 5 for the displacement of the sliding clutch member 3 in the driving direction can be changed;

[0133] During the actual adjustment of the resistance gear, by controlling the rotation of the multi-gear limit member 5, the abutting position of the sliding clutch member 3 on the slope surface of the slope-shaped limit structure 51 can be changed. The spring 31 on the opposite side drives the sliding clutch member 3 to displace towards the damping mechanism 4 to achieve the cooperative locking with the damping mechanism 4. By abutting against the sliding clutch member 3 through the height difference of the slope surface, the displacement limit distance in the driving direction of the multi-gear limit member 5 on the sliding clutch member 3 can be changed. In this way, the driving force and the limiting force can be applied in two directions respectively, and the cooperative locking of the sliding clutch member 3 with one or more resistance mechanisms 4 can be achieved by adjusting the limit distance, that is, the resistance gear adjustment between the wheel body 1 and the central tube 2 is realized.

[0134] Further, the surface of the slope-shaped limit structure 51 is provided with the same number of gear slots 32 as the damping mechanism 4, as Figure 14 , Figure 15 shown;

[0135] The surface of the sliding clutch member 3 is provided with positioning blocks 33 adapted to the gear slots 32, as shown in 11, Figure 13 shown;

[0136] When the slope-shaped limit structure 51 and the sliding clutch member 3 are cooperatively abutted, the positioning blocks 33 can be clamped in the corresponding gear slots 32 to achieve locking, as Figure 13 shown;

[0137] It should be noted that the technical means for restricting and locking the displacement distance in the driving direction of the sliding clutch member 3 in this embodiment is only a preferred embodiment, and it should not be limited to adjusting the limit distance by rotating the multi-gear limit member 5.

[0138] In this embodiment, the edge of the gear slot 32 is provided with an arc chamfer 36, as Figure 14 shown;

[0139] The end of the positioning block 33 for clamping in the gear slot 32 is a circular arc end 37, as Figure 11 shown;

[0140] Through the cooperation of the arc chamfer 36 and the circular arc end 37, it is convenient for the positioning block 33 to escape from the gear slot 32 when the multi-gear limit member 5 rotates.

[0141] In this embodiment, the multi-gear limit member 5 is connected with a gear adjustment control member 6;

[0142] The gear adjustment control member 6 is rotatably connected to one side of the wheel body 1, as Figure 3 shown;

[0143] The gear adjustment control member 6 is fixedly connected to the multi-gear limit member 5, as Figure 9 shown; The gear adjustment control member 6 is used to control the rotation of the multi-gear limit member 5.

[0144] On one side of the wheel body 1, a gear shifting seat 62 is formed along the axial direction of the central tube 2, as Figure 17 shown;

[0145] The gear shifting seat 62 is a cylindrical structure, as Figure 16 shown;

[0146] One end of the gear shifting seat 62 is fixedly connected to one side of the wheel body 1, as Figure 17 shown;

[0147] The gear shifting control member 6 is a sleeve-like structure, and it is rotatably sleeved on one side of the gear shifting seat 62, as Figure 9 shown;

[0148] The gear shifting control member 6 can be rotated by the user on one side of the wheel body 1 by being sleeved on the gear shifting seat 62;
