Abstract
Description
- The present invention relates to weight training equipment, and more particularly to a weight plate gap adjustment device for weight training equipment.
- A weight training equipment usually has a plurality of weight plates stacked on the top of each other. A traction shaft is placed in the center of the weight plates, and the traction shaft is driven by pulling a steel cable to pull up and lower the weight plates to produce a weight training effect. When changing the load, a locking pin is used to pass through the weight plate at a different location and the traction shaft, so that the traction shaft drives the corresponding number of weight plates through the locking pin to achieve the training effect of adjusting the load.
- However, there are manufacturing tolerances in the matching aperture between the locking pin, the weight plates, and the traction shaft, resulting in a gap between the locking pin, the weight plates, and the traction shaft. As soon as the steel cable drives the traction shaft, it cannot directly move the locking pin and the weight plates. On the contrary, there will be problems of exerting force but not being able to move, and the fitness operation feels poor.
- The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a weight plate gap adjustment device for weight training equipment, which can reduce the gap between the weight plate and the related component, thereby improving the operating feel and movement intuition.
- To achieve this and other objects, a weight plate gap adjustment device is provided for use in a weight training equipment. The weight training equipment comprises at least one weight plate. Each weight plate has a hole penetrating a traction shaft. The weight plate gap adjustment device comprises a locking pin and at least one inserting member. The locking pin comprises a body. The body has a taper. The locking pin is detachably coupled to the hole of one weight plate and the traction shaft. Each inserting member comprises a coupling portion. The coupling portion has a taper corresponding to the taper of the body of the locking pin. Each inserting member is mounted in the hole of one respective weight plate so that when the locking pin is coupled to the hole of one weight plate, the body and the coupling portion are closely abutted with each other to eliminate the gap between the locking pin and the respective weight plate.
- Preferably, the locking pin is provided with a magnetic member. The magnetic force of the magnetic member attracts the locking pin and the respective weight plate.
- Preferably, the inserting member is in the shape of a sleeve, and the coupling portion is located on the inner circumference of the inserting member.
- Other and further benefits, advantages and features of the present invention will be understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference characters denote like elements of structure.

The weight plate gap adjustment device of weight training equipment provided by the present invention can be widely used in various fitness equipment with weight training boxes. Those skilled in the art can understand that the explanatory terms of this embodiment belong to the upper-level description that does not limit the application field. For example, the material or shape terms include but are not limited to the material or shape specified by the description content, and the position terms include but are not limited to setting, proximity, connect, or adjacency. The term “one” for the quantity of each component includes one and more than one component quantity. The directional adjectives mentioned in the content of this specification, such as “upper”, “lower”, “inner”, “outer”, “top”, “bottom”, etc. are only exemplary descriptions based on the normal direction of use and are not intended to limit the scope of claims.
- Referring to
FIGS. 1-5 , a preferred embodiment of the present invention takes a weight training equipment with a weight training box as an example. The weight training equipment includes a plurality ofweight plates 10 stacked on each other. Eachweight plate 10 has ahole 12, and thehole 12 of theweight plate 10 penetrates atraction shaft 14. - The weight plate gap adjustment device comprises a
locking pin 20 and aninserting member 24. Thelocking pin 20 has abody 22, and the outer circumference of thebody 22 is tapered. Thelocking pin 20 is detachably connected to thehole 12 of one of theweight plates 10 and thetraction shaft 14. - The
inserting member 24 is in the shape of a sleeve in this preferred embodiment. The inner peripheral surface of theinserting member 24 has acoupling portion 26, and thecoupling portion 26 has a taper. The taper of thecoupling portion 26 corresponds to the taper of thebody 22 of thelocking pin 20. - The
inserting member 24 penetrates the end edge of thehole 12 of eachweight plate 10, so that thelocking pin 20 is provided in thehole 12 of one of theweight plates 10, and thebody 22 and thecoupling portion 26 are in close contact with each other to eliminate the gap between thelocking pin 20 and theweight plate 10. - With the above components, the
locking pin 20 and theinserting member 24 of the present invention are tightly combined with each other by taper, which can reduce the gap between theweight plate 10 and thelocking pin 20, and achieve the purpose of the invention of improving the operating feel and movement intuition. - Furthermore, the
locking pin 20 may have amagnetic member 30, and the magnetic force of themagnetic member 30 attracts thelocking pin 20 and theiron weight plate 10, so that thelocking pin 20 is firmly set in theweight plate 10.
