Description
- 1. Field of the Invention
- The present invention relates to a slippers structure, and more particularly to a low cost, simply-structured and foldable slippers structure which can enhance the propulsion power, help the wearer achieve a better walking and standing posture and modulate the lower limb and body muscles.
- 2. Description of the Prior Art
- The flip flops often seen in the market, such as disclosed in TW Publication No. M289599 and Pat. No. M318938, mostly comprise a sole and a v-shaped vamp. One end of the vamp is integrally formed with a toe post which is permanently fixed to the sole together with another two ends of the vamp. Hence, the arched vamp has a relatively large size and makes it inconvenient to store. It will take a lot of space during transportation when the flip flops are packed into boxes. Furthermore, the enamel is likely to contaminate the vamp when a foot with freshly polished nails steps in the small space defined between the vamp and the sole. Therefore, it causes inconveniences since the user whose toenails are freshly polished cannot wear the flip flops until the enamel is dry. On the other hand, the three ends of the vamp are fixed to the sole, which makes the manufacturing process complicated. Besides, the vamp and the sole have to be formed differently by two different modules, resulting in an increase in manufacturing cost. Specially, the bottom of the sole is mostly flat, when walking, the heel and the metatarsus which support most of the body weight are unable to touch the ground smoothly because of the flat bottom of the sole, making walking uncomfortable and laborsome. Furthermore, the portion of the bottom of the sole corresponding to the heel is most likely to wear off, and more specially, the flat bottom surface of the sole has an influence on wearer's walking posture and might cause damage to the wearer's lower limb muscle and body muscle.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
- The primary object of the present invention is to provide a low cost, simply-structured and foldable slippers structure which can enhance the propulsion power, help the wearer achieve a better walking and standing posture and modulate the lower limb and body muscles.
- A slippers structure in accordance with the present invention comprises: a sole, a toe post and a vamp. The sole is defined at its front end with a concave, and close to a middle of both lateral edges of the sole is formed a protruding portion, respectively, a bottom of the sole is formed with an arc-shaped surface extending from a front end to a rear end thereof. The toe post includes a post portion and a head portion, the post portion has one end integrally formed with an inner side of the concave and is capable of being folded upwards at an angle, the head portion is located at the other end of the post portion and has a larger diameter than the post portion. The vamp has two ends integral with the protruding portions of the sole and is located around an outer periphery of a rear half of the sole in such a manner that an interval is left between the rear half of the sole and an inner edge of the vamp, an engaging portion extends from the inner edge to near a center of the vamp, the vamp is capable of being folded upward over the sole from its two ends connected to the two protruding portions, and the toe post is engaged in the engaging portion.
- With the design that the vamp and the toe post can be upward folded and engaged with and disengaged from each other, when the slippers are not worn or during transportation, the vamp can be released from the toe post and unfolded to its original non-use position, which facilitates packing and transport. Furthermore, the arc-shaped surface of the bottom of the sole can enhance the propulsion power, help the wearer achieve a better walking and standing posture and modulate the lower limb and body muscles.
