DETAILED DESCRIPTION OF THE INVENTION
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to FIGS. 1 and 2, the perspective view of the present invention is illustrated. The multi-functional retaining strap 1 of the present invention is a belt. The multi-functional retaining strap 1 has two strap surfaces 10, 11. Each strap surface is installed with attachable tapes, such as loop tapes or hook tapes, or fasteners with loops or fasteners with hooks.
A short extending retaining strap 2 has one end fixed to a middle section of the strap surface 10 of the multi-functional retaining strap 1 and another end which is not fixed. A surface of the short extending retaining strap 2 is an attachable tape.
An inner folded strap 3A is attached to the strap surface 10. At least one surface of the inner folded strap 3A is an attachable tape.
An outer folded strap 3 has two ends fixed to the inner folded strap 3A. A gap is formed between the inner folded strap 2 and the outer folded strap 3. At least one surface of the outer folded strap 3 is an attachable tape.
The uses of the present invention will be described herein. Referring to FIGS. 3A and 3B. For example, as an MP3 is desired to be carried with the body, the short extending retaining strap 2 can pass through a combining hole of an MP3 protecting cover 4 (at the backside). Then the short extending retaining strap 2 is folded to pass through the gap between the inner folded strap 3A and the outer folded strap 3. The free end of the short extending retaining strap 2 is then fixed to the attachable tape of the strap surface 10.
Referring to FIG. 5, the present invention can be wounded to has a compact size. FIG. 4 shows that the present invention is wound as a larger ring.
Referring to FIG. 6, it shows that the ring of the present invention can be retained around the wrist.
Referring to FIG. 7, it shows that the multi-functional retaining strap 1 of the present invention can be wound to have a desired thickness so that the present invention is wound around the wrist as a protecting pad and as a supporter when the user operates a computer mouse 5. Referring to FIG. 7A, another application of the present invention is illustrated. The multi-functional retaining strap 1 can be folded along an Z path so as to have a greater thickness.
Referring to FIG. 8, the present invention can be used to confine a trouser tube so as to avoid the trouser to be caught by a gear in driving a bicycle or an automobile.
Referring to FIG. 9, two multi-functional retaining straps 1 can be combined and then retained on the forehead of the head.
Besides, the multi-functional retaining strap 1 can be wound around the handle of a bicycle 8 and then an electronic watch 7 is fixed to the multi-functional retaining strap 1 as a timer. Thereby the user can see the indications on the panel of the electronic watch 7 as desired, as shown in FIG. 10,
Referring to FIG. 11, in one another of the present invention, the multi-functional retaining strap 1 can pass through a kettle frame 9 as illustrated in the drawing. By adjusting the ring size of the multi-functional retaining strap 1, the multi-functional retaining strap 1 can be used to fix containers of different sizes.
Referring to FIG. 12, in the present invention, an auxiliary strap 12 is provided. One surface of the auxiliary strap 12 is formed with an attachable tape. One end of the auxiliary strap 12 can be fixed to the short extending retaining strap 2 so as to prolong the length of the short extending retaining strap 2. In use, the combination structure of the short extending retaining strap 2 and the auxiliary strap 12 can pass through the kettle frame 9. Then another end of the auxiliary strap 12 is fixed to the strap surface 10 of the multi-functional retaining strap 1. Thereby the container on the kettle frame 9 is firmly secured to the kettle frame 9 without vibrations.
It should be noted that in the present invention, the attachable tapes is such as loop tapes or hook tapes, or fasteners with loops or fasteners with hooks.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
