ABSTRACT:
BACKGROUND OF THE INVENTION
(a) Technical Field of the Invention
The present invention relates to a combination type of floating cylinder for swimming and storing articles or the like, and in particular, a floating cylinder of various combination structures for swimming, or swimming-training, or storing articles, belongings or the like of the user.
(b) Description of the Prior Art
Swimming is a popular exercise, which does not require expensive equipment or location and does not restrict to age limits. However, in learning swimming, a plurality of training devices, for instance a life-ring, a life-vest, a floating board may be provided, but these devices do not suit everyone with different physical weight and size. Thus, the function of these devices, or the result of swimming training by using these devices is very limited. For instance, in learning or water stroking by hands, the legs and the lower part of the body has to be kept afloat with a floating device, and the floating device must be suitably for every individual. However, the conventional life-ring, life-vest and floating board are of fixed floatation force and there are not suitable for every one of different physical size and weight. If the floatation force is to be adjusted to suit a particular person, an additional life-ring, life-vest of floating board with extra floatation force has to be used. Thus, it is not convenient for the user. If the riser only considers the floatation force of the floating device, the drawback of the floating device may pose another problem, and the user may lose interest in learning how to swim. Thus, it is a need to provide a device where the floatation force can be adjusted depending on the physical size or weight of the user.
Additionally, other than the floatation force of the floating device being non-adjustable, the floating device also does not allow the user to hold the floating device in a convenient way. The conventional floating device cannot be easily held or cannot be held with the legs of the users. In other words, the floating device may be easily dislocated or slipped off from the user. To solve this problem, a cable or a fixing strap is used to tie to the legs or hands of the user. But this will cause the hands or legs being clumsy and the balancing of the user while swimming may be affected. Consequently, the user may have an inaccurate swimming style. Other drawback of the conventional floating device is that belongings of the users, such as wallet, spectables, watch, T-shirt, jewelry cannot be kept while swimming, and it may not be convenient if the conventional floating device is to be used in a river or waters where there is no deposit box to keep the belongings of the swimmers.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a combination type of floating cylinder for swimming and storing articles, wherein a plurality of base floating cylinders, secondary floating cylinder, and fins which can be mounted to each other, and can be freely configured into floating cylinder structure of various floatation force value, adapt to users of different physical sizes and weight, and under different usage by adjusting the value of the floatation force.
Yet another object of the present invention is to provide a combination type of floating cylinder for swimming and storing articles, wherein the base floating cylinder and the secondary floating cylinder are provided to contain articles or belongings while swimming. Thus, the articles or the belongings of the swimmer do not require to be kept by others.
A further object of the present invention is to provide a combination type of floating cylinder for swimming and storing articles, wherein a plurality of fins are provided between the base floating cylinder and the secondary floating cylinder.
Yet another further object of the present invention is to provide a combination type of floating cylinder for swimming and storing articles, wherein a hook for connection with a fastening member of a cable are respectively mounted to the base floating cylinder, the secondary floating cylinder and the cylindrical base, the fastening member being tied to the swimmer while swimming to carry the belonging together with the swimmer.
A further aspect of the present invention is to provide a combination type of floating cylinder for swimming and storing articles comprising at least a base floating cylinder, and a secondary floating cylinder both being hollow, and a plurality of fins. The surrounding surface of the floating cylinder is provided with at least a dovetailing seat. One end of the floating cylinder is provided with a hook, and the other end is provided with a removable cap body which can be opened and shut for the storage of articles or the like within the interior of the base floating cylinder or the secondary floating cylinder. A plurality of protruded seats are provided along the surrounding surface of a cylindrical base, one end of the dovetailing seat being an urging cap which can be tightly fastened to the dovetailing seat, and the other end being a hook. The two side edges are respectively provided with a protruded edge or engagement with the dovetailing seat of the base floating cylinder and a secondary floating cylinder and the two cylinders are combined together or respectively mounted to the cylindrical base or the dovetailing seat of the secondary floating cylinder such that the cylindrical base is joined with the floating cylinder configurations with different floatation force can be formed, and the hooks of the base floating cylinder, the secondary cylinder or the cylindrical base are used in combination with the cable mounted to the user.
