Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used, for example, for swimming training (training), and enables a swimmer to practice competition without the need of a coach or the like, and to correctly grasp and confirm a predetermined swimming pace. The present invention relates to a traveling device for a training target that can be used.

[0002]

2. Description of the Related Art For example, means for confirming a player's own pace during swimming practice (training) can be determined by checking a time-measuring device near a pool by himself / herself or by a coach or an assistant having a stopwatch. The means of receiving announcements were common. However, even if you check the timekeeping device yourself or receive an announcement from a coach or the like, it is difficult to reliably grasp an appropriate and accurate pace during swimming, so after one practice is over, As a result, it was only possible to judge the result based on the quality of the (time required). In addition, when swimmers having different swimming styles and abilities perform exercises in parallel, there is a problem that coaching or guidance by an assistant to each of them may cause confusion.

[0003] In view of such circumstances, there have been proposed some exercise apparatuses for improving the record of swimming without attaching a coach or an assistant. For example, JP-A-3-1
No. 43,664 discloses that a light bulb or L is provided on the bottom of a pool.
There is disclosed an arrangement in which light sources such as EDs are arranged in a chain and the light sources are sequentially turned on in accordance with a target speed for practice. According to this, the swimmer can grasp a predetermined pace by training for the light source that is turned on. However, when using this device, it is possible to confirm the light source during crawl, butterfly, or breaststroke practice, but in backstroke practice, because the swimmer's visual direction does not match the light source, There is a problem that this cannot be used.

As another example, for example, Japanese Patent Publication No.
As disclosed in Japanese Unexamined Patent Publication No. 3627, a dedicated small pool is prepared, a water discharge pump generates a water flow at a target speed, and the swimmer swims so as not to lose its relative position against the water flow. It has been proposed that the player can learn the pace by doing so. In such a device, it is necessary to realize a water flow in a state where a width of one course in an actual pool and a predetermined water depth are secured, and the mechanical equipment including a pump becomes enormous. Have.

However, most of these pools are not provided with special facilities for obtaining a pace, and laying the above-mentioned facilities on existing pools is not practical in terms of remodeling work and costs. is not. One of the functions required of a training device for acquiring a pace is that the installation or removal of the existing pool should be simple and easy.

In the case where the light source is installed on the bottom of the pool, it is necessary to lay an electric cable for controlling lighting of the light source. Laying electric cables underwater creates a fear of electric shock for swimmers and creates a feeling of psychological oppression. It is natural for swimmers to want to learn in a pool and course environment that is no different from before.

[0007] In order to ensure the mastery of the pace,
It is not enough for the swimmer to visually determine the swimmer's time since the start, and the swimmer of the target pace is swimming in the vicinity, and the practice swimmer follows it, feeling a sense of realism or urgency. It is desired to make it.
It is also desired that the swimmer be allowed to experience a simulated competition for the entire competition distance. In particular, recent competition practice methods do not adopt the method of swimming over the full length of the competition distance, but instead divide into the initial distance including the start, the middle distance, and the end distance including the last spurt. The practice is repeated. This is said to be the best way to get the water flow in each section on the skin.

[0008] The traveling device of the training target according to the present invention,
The present invention has been made in view of the above request and the current training method, and is easy to install or remove from an existing pool, and traveling of a training target that can easily carry the equipment. It is intended to provide a device. It is another object of the present invention to provide a training target traveling device that can ensure the visibility of a training target in any swimming method and that can repeatedly realize speed control corresponding to a practice menu. It is assumed that.
