Abstract
A fitness expander includes at least two through holes positioned on the two handles respectively, a metal fastening ring is arranged on the through hole, a hollow hose with two anti-slip devices on each of the distal ends thereof is inserted through the metal fastening rings. The present invention features on that the anti-slip device is a soft and hollow cone on whose circumference a plurality of thin and elastic rings are mounted at regular clearance. While the hollow hose is pulled, the elastic rings of the anti-slip device are deformable for expanding the contact surface of the hollow hose with the fastening ring so as to avoid the abrasion of the hollow hose by metal fastening rings.
Description
- 1. Field of the Invention
- The present invention relates to a fitness expander, especially one having a plurality of hollow hose with anti-slip device therein arranged between two handles. The anti-slip device is composed of a soft and hollow cone with a plurality of elastic rings so as to make the anti-slip device contact the hollow hose in a certain area while being expanded for preventing the hollow hose from abrasion and slipping away.
- 2. Description of the Prior Art
- Conventional fitness equipment for training chest muscle includes man-sized equipment with adjustable load or undersized equipment such as fitness expander with springs. For home fitness, people tend to use the fitness expander having a plurality of springs arranged between two handles. By pulling two ends of the fitness expander, the finest pectoral workout is available.
- However, the conventional fitness expander occupies quite large space because the springs are not foldable. It's also quite heavy. Moreover, the sweat with salt produced during exercise is easy to make the surface of the springs rusty. The inner surface of the spring is also difficult to maintain thus cause inconvenience.
- Refer to FIG. 8, the spring is replaced by a hollow hose. The device includes two handles (a), each having at least two holes (a1), a metal fastening ring (b) is positioned on the hole (a1). A hollow hose (c) is inserted through and connected between the two metal fastening rings (b) on the handles (a) respectively, and an anti-slip ball (d) is positioned on each of two ends of the hollow hose (c) for fixing the hollow hose (c) on the handles (a) by the anti-slip ball (d) leaning against the metal fastening ring (b), as shown in FIG. 9.
- However, when the hollow hose (c) is pulled and extended, the diameter thereof is contracted so that the anti-slip ball (d) make the stretching area on the outer surface of the distal end of the hollow hose (c) contact the metal fastening ring (b) in circular line, as shown in FIG. 10. While when the hollow hose (c) is loosened, it turns back to the original length. During the process of contraction and stretch, the extended area on the outer surface of the distal end of the hollow hose (c), contact with the metal fastening ring (b), is easy to be worn-out. When being abraded in a certain degree, the hollow hose (c) breaks off. This causes users accidental harms.
- Moreover, refer from FIG. 11 to FIG. 13, even a prior art having a cylindrical anti-slip device (f), a rivet-like anti-slip device (g) or I-shaped anti-slip device (h) instead of the anti-slip ball (d), the problem of worn-out of hollow hose (c) by the anti-slip devices still exists. There is still a need for improvement.
- It is therefore a primary object of the present invention to provide a fitness expander having a plurality of hollow hose with two anti-slip devices on two distal ends of the hollow hose, disposed between the two handles. The anti-slip device is a soft and hollow cone with a plurality of and elastic rings thereon so that the contact of the anti-slip device with the hollow hose forms a plane while the hollow hose is stretched.
- Thus the abrasion of the hollow hose by the anti-slip device can be avoided.
- The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:
- FIG. 1 is a front view of the present invention;
- FIG. 2 is a perspective view of the present invention;
- FIG. 3 is a cross-sectional view of the present invention not being put on loading;
- FIG. 4 is a cross-sectional view of the present invention while being put on loading;
- FIG. 5 is another embodiment of a anti-slip device in accordance with the present invention;
- FIG. 6 is a cross-sectional view of another embodiment of the present invention not being put on loading;
- FIG. 7 is a cross-sectional view of another embodiment of the present invention while being put on loading;
- FIG. 8 is a front view of a prior art;
- FIG. 9 is a cross-sectional view of the prior art not being put on loading;
- FIG. 10 is a cross-sectional view of the prior art while being put on loading;
- FIG. 11 is a cross-sectional view of another prior art;
- FIG. 12 is a cross-sectional view of a further prior art;
- FIG. 13 is a cross-sectional view of a further prior art.
- Refer to FIG. 1, the present invention having two
handles 1, each with at least two throughholes 11, ametal fastening ring 2 clipped and positioned on the throughhole 11, ahollow hose 3 inserted through the two correspondingmetal fastening rings 2 on each of thehandle 1, twoanti-slip devices 4 mounted in the two distal ends of thehollow hose 3 for extending thehollow hose 3 and leaning on themetal fastening ring 2. This make the two ends of thehollow hose 3 being fixed firmly on the each of thehandles 1 respectively. The present invention features on that theanti-slip device 4 is made of soft material and is ahollow cone 41 with a plurality of thin andelastic rings 42 disposed on the circumference thereof. Refer to FIG. 2 & FIG. 3, when the hollow hose is pulled, each of the thin andelastic rings 42 deforms and contacts the inner face of thehollow hose 3. The contact area between thehollow hose 3 and themetal fastening ring 2 is not a circular line but a plane, as shown in FIG. 4. Thus thehollow hose 3 will not be worn out by themetal fastening ring 2. - In accordance with the structure mentioned above, when the
anti-slip device 4 is mounted inside thehollow hose 3, the two hands of users hold the two handles respectively without putting any loading on the present invention and thehollow hose 3 is not stretched, each of the thin andelastic rings 42 on thecone 41 of theanti-slip device 4 lean on the inner surface of thehollow hose 3 in parallel, as shown in FIG. 3. While the users' hands put loading on the present invention, thehollow hose 3 is pulled and the diameter thereof is shortened so that theanti-slip device 4 slides into themetal fastening ring 2 and each of the thin andelastic rings 42 on thecone 41 thereof deforms and contact the inner surface of thehollow hose 3 in a plane. Refer to FIG. 4, thus the contact of thehollow hose 3 with themetal fastening ring 2 also forms a plane. And thehollow hose 3 is fixed firmly on themetal fastening rings 2 of thehandles 1 by thecone 41 of theanti-slip device 4. Therefore, when thehollow hose 3 is stretched or contracted by loading, the friction due to the siding between thehollow hose 3 and themetal fastening rings 2 can be reduced so as to avoid the worn-out and the breakage of thehollow hose 3. - Refer to FIG. 5, the anti-slip device4 a can be designed to have two
small cones 41 a, positioned opposite to each other. Thus the anti-slip device 4 a can be mounted into thehollow hose 3 bi-directional for convenient assembling. The two ends of thehollow hose 3 is connected together to form a loop, as shown in FIG. 6 and FIG. 7. This is another embodiment of the present invention. - It should be noted that the above description and accompanying drawings are only used to illustrate some embodiments of the present invention, not intended to limit the scope thereof. Any modification of the embodiments should fall within the scope of the present invention.
