Footwear with improved straps
A footwear with improved straps, which has a sole, a first strap, which has a hollow tubular strap body made from elastic plastics or rubber, a first mounting portion disposed at one end of the strap body and affixed to said sole and a second mounting portion disposed at the opposite end of the strap body, and a second strap, which has a hollow tubular strap body made from elastic plastics or rubber and connected to the second mounting portion of the strap body of the first strap and two mounting portions respectively disposed at the two distal ends of the strap body thereof and respectively affixed to the sole. In an alternate form of the invention, the first strap and the second strap are respectively affixed to the sole and set apart.
1. Field of the Invention
The present invention relates to footwear and more particularly, to a footwear having improved straps.
2. Description of the Related Art
The straps of a conventional footwear are commonly molded from plastics or rubber, and fastened together to form a Y-shaped or X-shaped structure, or separately fastened to the sole to form a respective loop. Because the straps are solid straps and having a hard contact feeling. When the user is running or jumping, a friction resistance is produced against the user's foot, causing the foot of the user to feel uncomfortable or to be injured.
A solid strap for footwear has a hard surface. When the sink of the foot is rubbing against the hard surface of the solid strap, a great friction resistance is produced against the skin of the foot. The friction resistance is relatively increased when the user is running or jumping, thereby causing the user to feel uncomfortable or the skin of the foot to be injured.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a footwear with improved straps, which gives a comfort wear to the user. It is another object of the present invention to provide a footwear with improved straps, which has a high tensile strength.
To achieve these and other objects of the present invention, the footwear with improved straps comprises a sole, the sole having a sole member; a first strap, the first strap having a hollow tubular strap body made from elastic plastics or rubber, a first mounting portion disposed at one end of the strap body of the first strap and affixed to the sole, and a second mounting portion disposed at an opposite end of the strap body of the first strap; and a second strap, the second strap having a hollow tubular strap body made from elastic plastics or rubber and connected to the second mounting portion of the strap body of the first strap, a first mounting portion disposed at one end of the strap body of the second strap and affixed to the sole, and a second mounting portion disposed at an opposite end of the strap body of the second strap and affixed to the sole.
In an alternate form of the invention, the first strap and the second strap are respectively affixed to the sole and set apart.
Referring to
The sole 10 has a sole member 11.
The first strap 20 has a hollow tubular strap body 21 molded from elastic plastics or rubber, a first mounting portion 22 at one end of the strap body 21, and a second mounting portion 23 at the other end of the strap body 21 relative to the first mounting portion 22.
The second strap 30 has a hollow tubular strap body 31 molded from elastic plastics or rubber for the connection of the second mounting portion 23 of the first strap 20, a first mounting portion 32 and a second mounting portion 33 respectively formed on the two distal ends of the strap body 31 and fixedly fastened to the sole member 11 of the sole 10.
Because the first strap 20 and the second strap 30 are tubular members of elastic plastics or rubber, they can absorb shocks when the user is running or jumping, giving a comfort wear to the user. Further, the first mounting portion 22 of the first strap and the two mounting portions 32 and 33 of the second strap 30 are made relatively greater in diameter than the straps 20 and 30 to enhance the tensile strength of the straps 20 and 30.
According to the embodiments shown in
In the aforesaid various embodiments, the mounting portions of the first and second traps have a relatively greater diameter for mounting. Alternatively, locating rings 40 can be affixed to the ends of the straps for mounting as shown in
Further, the first strap and the second strap can be made in integrity, or fastened together by fusing or high-frequency heat sealing to save the manufacturing cost.
As indicated above, the invention has the following benefits:
1. The elastic hollow tubular first strap and second strap of the footwear absorb shocks and reduce friction, giving a comfort wear to the user.
2. By means of increasing the diameter of the ends of the first and second straps or providing locating rings or binding cord members at the ends of the first and second straps for mounting, the straps can bear a high pulling force.
