Power Transmitting Apparatus for Moter Running Machine

The present invention relates to a power transmission device of an electric treadmill. In particular, it is a power transmission device of an electric treadmill that allows families or dogs to work together by transmitting the rotational force of a general electric treadmill that a person moves to the roller shaft of a non-power auxiliary treadmill so that they can work together. .

The number of people raising dogs has been increasing recently, and everyone can see that the industry for dogs is rapidly developing. The dog industry is divided into various fields such as food, hospital, beauty, supplies, pre-sale industry, education, and health, and is tailoring the tastes of people who raise dogs with unique idea products for each field. Invented for the field.

Recently, a dog-only treadmill has been developed, released, and used for the exercise of a dog. Such a treadmill is operated by the operation of the dog's attention, and the dog is exercising alone. However, this invention is a product of human-centered thinking, and thus lacks an understanding of the intellectual ability or the nature of the dog, which is a party to use, and thus, the dog owner has many difficulties in exercising the dog or obtaining the dog's exercise effect.

First, dogs do not have the purpose of exercising because they do not realize that they are healthy when they exercise. Therefore, dogs do not run steadily even if the dog is difficult when exercising on the treadmill.

Second, dogs have a lot of curiosity about new things, but they also have fears, so they don't hesitate to run on treadmills.

Third, dogs were originally hunting and acting in a group, and even in the present day, they have imitations to follow and learn from their owners and other dogs, and have fun habits when they hang out together. It's hard and doesn't interest me.

In addition, dog owners can purchase dog treadmills separately and exercise together to improve these problems, but the purchase cost is high, and it is troublesome to operate two treadmills separately at the start and end of the exercise. In addition, it is not easy to respond quickly in case of emergency during exercise.

Meanwhile, Korean Patent Publication No. 2003-0068099 (published date: 2003.8.19) discloses a dog treadmill that can maintain or improve the health of a dog through indoor exercise. The dog's treadmill is cyclically mounted on a support frame structure supported on the ground and rotatably mounted on a running belt and a support frame structure moving along the longitudinal direction to support both ends of the running belt and to bind and rotate with the running belt. It includes a roller member. The treadmill configured in this way can exercise the dog regardless of the place, indoors or outdoors, and can steadily exercise the dog even during the day when the house is empty. Even if it's raining or cold, you can continue to exercise to make up for your dog's lack of exercise. However, this publication merely discloses the construction and operation of dog treadmills and does not mention the technique of exercising with people. As such, the prior art does not understand the characteristics of the dog, and simply manufactures by changing or reducing the electric treadmill used by people, and thus there is a lack of exercise equipment including a treadmill suitable for the dog.

An object of the present invention has been made in view of the above problems, by transmitting the rotational force of a general electric treadmill that a person moves to the roller shaft of a non-powered auxiliary treadmill to work together, family at home or Provides a power transmission device of the electric treadmill that can be exercised with the dog.

It is another object of the present invention to provide a power transmission device for an electric treadmill that can easily adapt to a treadmill, easily operate and use the treadmill, and cope quickly in an emergency situation.

The present invention is a domestic priority claim of the first application No. 2003-76388 (application date: 2003.10.30) filed to improve the problem of the previous application to the power transmission of other methods that can easily connect and disconnect the auxiliary treadmill and the general electric machine It is to provide a device.
