Description

A track-type abdominal fitness device Technical Field

[0001] The present invention relates to the field of fitness equipment, and more particularly to a track-type abdominal fitness device. Background Art

[0002] Currently, abdominal exercise equipment on the market is divided into large abdominal exercise machines used in gyms, depending on the usage scenario. These generally consist of a large frame with handles at the top and a sliding pad for the user to kneel on. The user uses their lower limbs to pull the sliding pad to exercise their abdomen. Due to the overall complexity and large size of the equipment, it is not suitable for home abdominal exercise.

[0003] Therefore, a new type of small abdominal wheel has appeared on the market. Its structure is shown in patent CN219110760U, which includes an elbow support, a support rod and two wheels arranged in front and behind. The user's elbows are supported on the elbow support, and the hands are held on the support rod. The user pushes the wheel forward and pulls the wheel back to perform abdominal exercises. Although the current two-wheeled abdominal wheel has increased overall stability compared to the previous one-wheeled abdominal wheel, since the user does not always keep the body trunk aligned with the axial direction of the abdominal wheel during use, it is easy to deviate during use, and therefore there is still a threat of tipping over during use.

[0004] Therefore, there is a great market demand for a new abdominal fitness device with a stable structure, and a small abdominal fitness device suitable for home use.

[0005] Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention aims to provide a track-type abdominal trainer with a stable structure. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a track-type abdominal trainer comprising a base, wherein the base is provided with a track arranged along the front-to-back direction of the base;

[0007] A sliding member is provided on the base, and the sliding member is slidably connected to the track;

[0008] The sliding member includes an elbow support portion and a hand-holding portion, wherein the hand-holding portion at least partially extends toward an end portion of the elbow support portion in a forward direction.

[0009] When using it, the user supports the elbows on the elbow support part, holds the handhold part, and exercises the abdomen by pulling the sliding part back and forth along the track after bending over. When bending over, the exerciser can kneel on one end of the base or move the sliding part in a plank support manner.

[0010] The base is provided with a track to guide the user's forward and backward movement direction, and the overall stability is not easy to fall over. The elbow support is provided to keep the user's support center of gravity stable during exercise, preventing the sliding part from falling off the track.

[0011] As a further improvement of the present invention, the track includes a positioning track and a sliding track, the sliding member is provided with a positioning block and a rolling member, the positioning block slides in the positioning track, and the rolling member rolls in cooperation with the sliding track.

[0012] By adopting the above technical solution, the sliding member can be further stabilized when moving forward and backward, and can effectively prevent the sliding member from falling off the track.

[0013] As a further improvement of the present invention, the base is provided with an elastic rope, and a rope winding member is provided on the base. The elastic rope includes a first connecting end and a second connecting end. The first connecting end is connected to the base, and the second connecting end is connected to the sliding member after the elastic rope passes around the rope winding member.

[0014] The elastic cord increases the forward resistance of the slider, allowing greater force to be applied during exercise. It also provides a restoring force during the slider's return stroke, reducing the difficulty of exercising with the abdominal trainer. Furthermore, compared to prior art structures that use a torsion spring-type elastic body on the roller's rotating shaft to provide a restoring force, the torsion spring assembly structure and the provision of fixing nuts on both sides of the rotating shaft connecting the wheel and the mounting frame overcome the problems of noise during use and the tendency of the fixing nuts to loosen and disintegrate during long-term use. This makes the abdominal trainer more durable and less prone to noise.

[0015] As a further improvement of the present invention, the base includes an initial parking position for the sliding member, and the rope winding member is arranged on the end of the base away from the forward direction of the sliding member's initial parking position, and the elastic rope includes a first line segment, a bending segment and a second line segment, wherein the bending segment is located at the rope winding segment of the elastic rope, wherein the first line segment extends from the first connecting end to the bending segment, and wherein the second line segment extends from the second connecting end to the bending segment.

[0016] By providing a rope winding member and arranging the rope winding member on the rear side of the sliding direction of the initial parking position of the sliding member, during the user's abdominal exercise, the elastic resistance of the elastic rope from the initial parking position of the sliding member to the movement to the other end of the base track is maintained within a reasonable range, and the durability of the elastic rope is improved.

[0017] As a further improvement of the present invention, when the elastic rope is in an unstretched state, the length of the first line segment is D1, the length of the second line segment is D2, and D1 and D2 satisfy 5≤D1:D2≤15.

[0018] By adopting the above technical solution, when the elastic cord is in an unstretched state, the distance between the connection end of the elastic cord with the slider and the winding member (i.e., D2) and the distance between the connection end of the elastic cord with the base and the winding member (i.e., D1) satisfy 5≤D1:D2≤15. This improves the fatigue resistance of the elastic cord while also taking into account the elastic resistance provided by the elastic cord and ensuring that the elastic resistance during movement of the slider remains within a reasonable range, so that the difference in elastic resistance between the starting position and the farthest position is not too large. Conversely, when D1:D2≤5, the closer the distance between the connection end of the elastic cord with the base and the winding member, the greater the elastic resistance it experiences at the farthest position of the slider, the lower the fatigue resistance of the elastic cord, and the greater the difference in elastic resistance between the starting position and the farthest position. When D1:D2≥15, the elastic resistance is too small to effectively provide a restoring force to the user during the return stroke. When D1:D2≥15, the elastic cord may slip out of the winding member during transportation or storage.

[0019] As a further improvement of the present invention, the first connecting end and the second connecting end of the elastic rope are in an expanded shape, and the expanded first connecting end and the second connecting end are respectively engaged with the base and the sliding member.

[0020] By adopting the above technical solution, the elastic rope is connected in a simple manner and can be firmly connected to the base and the sliding member.

[0021] As a further improvement of the present invention, the rope winding member is a fixed pulley, and the number of the fixed pulleys is two. The two fixed pulleys are arranged horizontally side by side along the width direction of the base. The second line segment is a bending section extension section formed on the second connecting end and the adjacent fixed pulley, and the second line segment is parallel to the axial direction in the length direction of the base.

[0022] By adopting the above technical solution, the first line segment is the distance between the connection end of the elastic rope and the base and the fixed pulley arranged near the sliding member, and the second line segment is the distance between the connection end of the elastic rope and the sliding member and the fixed pulley arranged near the sliding member. By setting the rope winding member as the fixed pulley, the sliding friction of the elastic rope is reduced. By setting two fixed pulleys arranged side by side horizontally to guide the second line segment to be perpendicular to the sliding member, the direction of the pulling force provided by the elastic rope to the sliding member is kept straight, so that the sliding member is smoother during the sliding process.

[0023] As a further improvement of the present invention, a resistance adjuster is provided on the base, and the resistance adjuster is used to adjust the elastic resistance of the elastic rope.

[0024] By adopting the above technical solution, the elastic resistance of the elastic rope can be adjusted by adjusting the resistance adjuster during use to meet the different resistance requirements of different groups for the abdominal trainer.

[0025] As a further improvement of the present invention, the resistance adjuster is a fixed pulley with a spiral groove, the elastic rope is wound around the fixed pulley with the spiral groove, and the resistance adjuster is provided with a rotating handle extending out of the base surface.

[0026] By adopting the above technical solution, the structure is simple and the adjustment method is convenient during use. The initial resistance of the elastic rope can be adjusted by simply turning the rotary handle. During use, in addition to the deformation resistance formed by stretching the elastic rope itself, the sliding friction force increased by the winding of the elastic rope in the spiral groove also increases the resistance, so that two resistance levels with obvious resistance value differences can be changed by turning the rotary handle 1-2 times.

[0027] As a further improvement of the present invention, the base includes at least two connecting plates assembled with each other.

[0028] By adopting the above technical solution, the base can be disassembled or folded to achieve miniaturization of the packaging of the abdominal trainer during sales and transportation. At the same time, consumers can also disassemble or fold it during use, so that it occupies a smaller area when stored.

[0029] As a further improvement of the present invention, the first connecting end of the elastic rope is connected to a connecting plate where the initial parking position of the sliding member is set.

[0030] By adopting the above technical solution, the elastic rope can be arranged in a connecting plate, so as to prevent the connecting plate from damaging the elastic rope during folding or disassembly, or the elastic rope from interfering with the folding or disassembly of the connecting plate when in use.

[0031] In summary, the present invention includes at least one of the following beneficial technical effects:

[0032] 1. By adopting the above technical solution, an abdominal tonic is provided which can maintain a stable center of gravity during use and is not prone to tipping over, so that exercisers are not easily injured during use.

[0033] 2. The elastic rope is provided to increase the forward resistance of the sliding part, thereby overcoming the problems of the prior art abdominal wheel making abnormal noises during use and the fixing nuts being easily loosened and disintegrated during the rotation of the wheel in the long term of use, making the abdominal wheel more durable and less likely to make noises.

[0034] 3. By adopting a rope winding member and limiting the position of the rope winding member and the distance between the two ends of the elastic rope and the rope winding member, the elastic resistance of the elastic rope from the initial parking position of the sliding member to the other end of the base track during the user's abdominal exercise is maintained within a reasonable range, while the durability of the elastic rope is improved.
