Description

Fitness wheel structure

This creation is about a fitness wheel, and refers to a fitness wheel structure that can adjust the displacement stroke to suit users of various body types.

Exercise wheels are common sports equipment on the market, and their basic types are as shown in my country Patent Bulletin No. 030499 and my country Patent Bulletin No. 216382, which are composed of more than one roller pivoted on a shaft. The user usually adopts a kneeling posture and holds both ends of the shaft with both hands to push forward and backward along its radial direction, so that the roller touches the ground to roll; through such reciprocating action, the user can achieve fitness effects.

In order to improve the effectiveness of the above exercise wheels, several improved designs of exercise wheels have been proposed so far. For example, the improved mechanism of exercise wheel in my country Patent Publication No. M347196 is composed of at least one shaft and one roller set. Wherein, the shaft is respectively provided with a left threaded portion and a right threaded portion at appropriate positions on its surface; the roller set includes at least a first roller, a second roller and a flexible element, wherein the first roller system Is sleeved on the left threaded portion of the shaft to generate a left spiral movement relative to the shaft, and the second roller is sleeved on the right threaded portion of the shaft to produce a right spiral movement relative to the shaft, The flexible element connects the first roller and the second roller to apply a pulling force (or thrust) between the first roller and the second roller. It is best that the first roller and the second roller system have the same outer diameter, and the first roller system has a left threaded central hole and the left threaded portion of the shaft. When engaged, the second roller system engages with the right threaded portion of the shaft through a right threaded central hole.

When the above exercise wheel holds both ends of the shaft with both hands and pushes forward along its radial direction, the first roller and the second roller system contact the ground at the same time to roll, and respectively move along the axial direction of the shaft Symmetrical translation, the first roller and the second roller system respectively perform left and right spiral motions relative to the shaft to move away from each other (or close to each other). In the process, the first roller and the second roller need to be connected against each other. The pulling force (or thrust) generated by the flexible element of the second roller, and through the flexible element, provides the resistance of the first and second rollers to slide forward in time, so as to prevent the user from insufficient strength or exceeding his own exercise capacity. People who are concerned about getting injured on the ground, but because the flexible element between the first and second rollers is a spring, there is still elastic fatigue after long-term use, and the resistance support effect cannot be effectively provided, so that the user is at risk of injury.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years, and after detailed design and careful evaluation for the above goals, he finally got a practical creation.

The technical problem to be solved by this creation is to provide a fitness wheel structure in view of the above-mentioned defects in the prior art.

The above structure includes: a shaft and a roller. The shaft has an outer thread section at the middle section and two sockets at both ends. The two sockets respectively pass through a grip, and the center of the roller is An inner threaded hole is provided, and the roller is screwed and assembled on the shaft rod along the outer threaded section through the inner threaded hole.

Preferably, the shaft is further provided with a limit screw, a screw hole is arranged in the center of the limit screw, and the screw hole is screwed on the outer thread segment.

Preferably, the limiting screw element penetrates the outer diameter surface and the inner diameter of the screw hole is provided with a The inner screw hole provides a stop screw for locking.

Preferably, a plurality of concave portions and convex portions are continuously formed on the outer diameter surface of the limiting screw.

Preferably, the outer thread segment is a sleeve with an outer thread, and is tightly sheathed at the center of the shaft.

Preferably, the sleeve is further piercedly connected with the shaft by at least two plug pins.

Preferably, one end of the outer thread segment has a blank segment without threads.

Preferably, one end of the outer thread segment has a larger outer diameter that abuts against the convex wall.

Preferably, the wheel surface of the roller is any type of flat surface, inclined surface and circular arc surface.

Comparing with the effect of the prior art: when the exercise wheel of this creation is pushed and pulled, the roller will move along the outer thread of the shaft at the same time, and the roller can be defined on the outer thread according to the body shape of the user. Segment displacement distance, and the position of the roller on the outer thread segment is used as the starting point for pushing the exercise wheel, and the grip is used as the end point for pushing the exercise wheel, so that the user can hold the exercise wheel and move towards When pushing forward, the roller can be pressed against the grip in time to stop pushing forward, avoiding insufficient strength and getting injured on the ground, so that the displacement stroke of the roller can be adjusted in advance according to different users, so as to meet the requirements of all users. , It is especially suitable for women or children with relatively petite body, which greatly improves the practicality of the structure.
