detailed description

[0019] Referring to FIG. 1 to FIG. 4, the complete swimmer is composed of two identical dumbbell-shaped hollow plastic articles, which can be used in two or a single use. Whether it is used alone or in combination, this article is called a swimming aid. The so-called bell shape refers to a long strip-shaped structure with thick and thin ends; the middle thin portion is convenient to hold by hand, and the thick portions of the two ends are favorable for generating sufficient buoyancy; the structure has good stability. Each support swimmer is provided with a protective cord (not shown) that can be placed on the hands or on the body to prevent drifting. The lightweight dumbbell-shaped swimming aid comprises an intermediate rod body 1 and a floating member 2 which is expanded at both ends; the floating member 2 can be specially designed to be integrally formed with the rod body, or can be sealed by various shapes (such as a plastic beverage bottle or an oil bottle). And so on, and then reliably connected to the rod.

[0020] The swimmer can be roughly divided into two types:

1. Mass production type: It is made of non-toxic lightweight plastic, hollow, two large, medium fine (Figure 1). The two large parts are floating parts with a total volume of 4-6 liters and 2-3 liters per head. The volume can be increased or decreased as needed to produce different types of swimmers for different groups of people. As long as the buoyancy generated by the swimming aid ensures that the swimmer can stand still in the water, the head can be exposed to the surface to breathe. The thin part in the middle is 2-4cm in diameter, usually 3cm, ensuring that the swimmer can easily hold it with one hand. To increase the strength of the swimmer, some lateral and longitudinal baffles can be added to the interior of the swimmer. Considering the buoyancy of the water, the upper and lower parts of the assisting device can be asymmetrical, generally large and small, which is beneficial to enhance the stability of use (Fig. 3 and Fig. 4). Can be designed as an open swimmer: If you have a jar screw with a sealing cap, you can use your inner space to carry valuables such as car keys, mobile phones, watches, etc.; Set some fixing ring holes, which can be easily installed with protective ropes. It is also convenient to upgrade the swimming aids yourself. (Adding appropriate mineral water bottles through the ring holes can upgrade the small swimming aids to medium or large swimming aids. ). In addition, the shape of the head at both ends of the swimming aid can be designed as needed, such as a rocket head shape, a shuttle shape, a spinning shape, a fish shape, etc., and the color and pattern of the swimming aid can be designed as needed. According to the above description, the swimmers described in this patent can be roughly classified into the following types:

Type I is "upper and lower symmetrical": that is, the upper and lower parts of the assisting swimmer are symmetrical with respect to the central axis, and the left and right parts are symmetrical with respect to the center line; this is the basic type of the swimming aid described in this patent. (figure 1 )

Type II is "upper and lower symmetrical left and right asymmetrical": that is, the upper and lower parts of the swimming aid are symmetrical with respect to the central axis, although the left and right parts are not Instruction manual

Symmetrical but basic shapes are the same, which helps to reduce the resistance of water. (figure 2)

Type III is "upper and lower asymmetrical left and right symmetrical": The upward facing portion is larger, which is beneficial to increase stability. (image 3 )

Type IV is "upper and lower asymmetrical": The combination of Type II and Type III is beneficial to increase stability and reduce water resistance. (Figure 4)

All the above models can be equipped with a jar screw and a sealing cover, so that the swimming aid has the function of a small valuables storage device; the fixing ring hole is added to make it self-upgrading function; the two ends are designed into different shapes and matched Available in different colors and patterns to provide both functional and decorative features.

[0021] 2, simple self-made type: 8-16 empty mineral water bottles (total volume of about 8-16 liters) are equally divided into four groups, each group of 2-4; then prepare two sections of plastic pipe about 60cm long ( The electrician used it to protect the wires), drilling both ends; using a self-made strong nylon rope to tie the water bottle symmetrically to the ends of the pipe through the holes in the pipe, a bottle at each end; Then attach a protective rope (when used, put it on your wrist to prevent it from drifting with water). In this way, a simple swimming aid is made. When you use it, you can take a hand in one hand, and the swimmer can safely go to the deep pool or the beach. As a reinforced type, a detachable sealed jar (with a carabiner for detachable function) can be added to one end of the tube as a temporary valuables storage.

[0022] In summary, the swimmer of the utility model has the following outstanding features:

1. Safe and reliable: B-bell shape, good stability; thin middle part for easy grip; protective rope, not easy to slip off, prevent drifting; inner cavity is supported by vertical and horizontal cross partitions, which can increase the strength of the force Therefore, the swimming aid is durable; the swimming aid can provide sufficient buoyancy (if it is not enough, it can be easily upgraded with an empty mineral water bottle), so that the swimmer can safely launch the water.

[0023] 2, light and environmentally friendly: The basic structure of the swimming aid is made of non-toxic lightweight plastic, which can be easily upgraded with an empty mineral water bottle. The price is low, light and environmentally friendly.

[0024] 3. Various functions: The swimming aid is held in the hand, or clamped under the armpit, or stepped on the sole of the foot, or floated beside the body, or sandwiched between the legs, and the manner of use is various. Hold in your hand to assist in freestyle (hold one hand, two hands take a stroke) or assist in the practice of leg movements in various strokes; clip under the armpit to hover in the water to rest, follow the waves, leisurely; Take a life-saving spare; step on the sole of the foot or clip it between the legs to increase the fun of playing. If you add a valuables storage box, you can also save the swimmers the trouble of storing items.
