Double head sleeper structure

Abstract

A double head sleeper structure mainly comprises a shoe body and two crossing shoestrings. The shoe body appears semicircular at both ends and a little concave in the middle of two sides. The size of shoe body varies to meet different user's need. The shoestring length is four fifth of the shoe body length. The two shoestrings cross with each other at the center of shoe surface of shoe body. The two ends of the shoestring attach the two opposite sides of shoe body at a position two third of the shoe body length from the shoe end. Such a design allows the user to put feet in shoes without need to watch for the shoe head direction. Particularly, when the feet are in shoes, the crossing point is forced to move a little forward, so the shoes look just like traditional design to cover the feet.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

Sleepers are a necessity for daily life and it provides convenience and comfort. In recent years, living standard is significantly improved.

2. Description of the Related Art

Sleeper design tends to be versatile and improving. However, current sleeper design limits the use to one direction, so users have to watch for shoe head direction before wearing shoes. This certainly causes some inconvenience

SUMMARY OF THE INVENTION

To improve quality of life and increase convenience, the inventor improved the current drawbacks for shoes and came up with a new shoe design. It is a double head shoe structure. When wearing or removing shoes, the user does not need to pay attention to shoe head direction. This design brings in much convenience by saving time and labor.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 1. The double head shoe structure in the present invention mainly comprises a shoe body 1 and two crossing shoestrings 2.

The shoe body 1 appears semicircular at both ends and a little concave in the middle of two sides. The length of shoe body 1 varies in three levels: large, medium and small to meet different user's need.

The shoestring 2 length is four fifth of the shoe body 1 length. The two shoestrings 2 cross with each other at the center of the shoe surface 11 of the shoe body 1. The two ends 21 of the shoestring 2 attach the two opposite sides of shoe body 1 at a position two third of the shoe body 1 length from the shoe end.

The attachment of the two ends 21 of the shoestring 2 is shown in FIG. 1 and FIG. 2 and is a direct clamping in a slot 13 between the shoe surface 11 and the shoe bottom 13. Alternatively, the attachment as shown in FIG. 3 and FIG. 4 can be a direct placement into a through hole 14 from shoe surface 11 to shoe bottom 12. The slot 13 (as position A in FIG. 2) or the through hole 14 (as position B in FIG. 4) is a little larger than the shoestring 2 width, so it allows the shoestring 2 to move around at a small angle, which also facilitates the movement of the crossing point of the shoestrings 2. Besides, the design also allows the foot 3 to have some maneuvering space in the net of the shoestrings 2 (as shown in FIG. 5). This allows more comfort for the foot 3 in the sleeper (as shown in FIG. 6).

Therefore, the user does not need to watch for the shoe head direction before putting feet 3 in the shoe body 1. The foot 3 can go into the shoe body 1 from either end and force the crossing point of the shoestrings 2 to move a little forward. The shoes finally look just like traditional design to cover the feet. The shoes also provide the user with required sturdiness and comfort.

In summary, the double head shoe structure in the invention does provide a way to overcome the drawbacks for traditional sleeper design, so it does not need to watch for shoe head direction. It provides timesaving convenience and certainly possesses progressiveness and commercial value.

Claims

1. A double head sleeper structure mainly comprises a shoe body and two crossing shoestrings; the shoe body appears semicircular at both ends and a little concave in the middle of two sides; the size of shoe body varies to meet different user's need; the characteristics are as follows:

the shoestring length is four fifth of the shoe body length;

the two shoestrings cross with each other at the center of shoe surface of the shoe body;

the two ends of the shoestring attach the two opposite sides of shoe body at a position two third of the shoe body length from the shoe end.

2. As described in claim 1 for a double head sleeper structure, the two ends of shoestring are directly clamped in a slot between shoe surface and shoe bottom.

3. As described in claim 1 for a double head sleeper structure, the two ends of shoestring are directly clamped in a slot between shoe surface and shoe bottom, the said slot opening is a little wider than the string width, so it allows the shoestring to move around at a small angle, which also facilitates the movement of the crossing point of the shoestrings; besides, the design also allows the foot to have some maneuvering space in the net of the shoestrings; this also allows more comfort for the foot in the sleeper.

4. As described in claim 1 for a double head sleeper structure, the two ends of shoestring are directly inserted into a through hole from shoe surface to shoe bottom.

5. As described in claim 1 for a double head sleeper structure, the two ends of shoestring are directly inserted into a through hole from shoe surface to shoe bottom; the said through hole opening is a little wider than the string width, so it allows the shoestring to move around at a small angle, which also facilitates the movement of the crossing point of the shoestrings; besides, the design also allows the foot to have some maneuvering space in the net of the shoestrings; this also allows more comfort for the foot in the sleeper.
