Tripping prevention footwear device

Abstract

To provide walking footwear useful to prevent tripping while walking and reduce accidents such as injuries caused by falls.SOLUTION: A method for unintentionally stepping over a protrusion on a walking surface includes: (i) causing a sensor to come into contact with an obstacle, compressing a leaf spring with tactile force, causing the leaf spring to bend and come into contact with the walking surface and lifting a tip of a sandal rise to step over the obstacle; and (ii) when a pedestrian steps on a pedestrian's toe-receiving sensor installed on a floor of the sandal while walking, causing a lever to lift a tip of the sandal to step over the obstacle.SELECTED DRAWING: Figure 3

Description

[Technical Field]

[0001] The present invention relates to an anti-trip device for walking footwear. [Background technology]

[0002] To provide a method for preventing accidents that have occurred frequently in the past, in which people in footwear trip over protrusions on the walking surface and fall, resulting in minor or serious injuries, not only among the elderly but also among ordinary citizens in the automobile society. [Prior art documents]

[0003] Summary of the Invention [Problem to be solved by the invention]

[0004] This had the following drawbacks: (a) In general, accidents involving tripping and falling while walking on footwear occur when there is a protrusion on the walking surface and the person is unable to step over it carelessly. However, existing sandals have remained the same in design for many years, and no measures have been taken to prevent this. Therefore, it has become necessary to develop measures to prevent tripping, especially for the elderly and people with reduced leg strength. (b) The upward curvature of the toe of existing sandals often causes tripping even when the protrusion is low. This is because when walking, the soles of the toes are in close contact with the walking surface, and as the foot moves forward, the heel rises, and even with the upward angle of the toe of existing sandals, it becomes the same level as an obstacle, so people with weak leg strength in particular need a device to prevent them from hitting the obstacle and tripping. Means to solve the problem

[0005] As a method for carelessly climbing over a protrusion on the walking surface, methods (a) and (b) are shown. In method (a), the toe of the sandal is raised at that point to climb over the protrusion obstacle. [Document name] [Drawing 1] Figure 8 The sensor (Figure 9) comes into contact with the obstacle, exerting a tactile force (Figure 10) compresses the leaf spring (Figure 11), which then bends and hits the walking surface (Figure 15), causing the tip of the sandal (Figure 7) to rise and climb over the obstacle. (b) Method: When the pedestrian steps on the toe support sensor (Figure 4) installed on the sandal floor (Figure 2), the lever (Figure 5) at the base point (Figure 2) raises the toe of the sandal (Figure 7) and overcomes the obstacle (Figure 8). In this way, the footwear trip prevention device invented this time is a footwear trip prevention device that includes two systems.

[0006] The present invention is useful for preventing tripping while walking and reducing accidents such as injuries caused by falls. [Brief explanation of the drawings]

[0008] Hereinafter, embodiments of the present invention will be described. Most existing sandals place emphasis on design, and these sandals have been developed with a particular focus on preventing tripping due to low-profile obstacles on the walking surface, helping to prevent accidents for the elderly and those with weak legs.

Claims

1. The tripping prevention device footwear of the present invention is a sandal to which the device is attached, and can be applied to other footwear to prevent tripping accidents.

2. This invention of footwear with a trip prevention device has two systems of prevention functions: an obstacle contact sensor on the walking surface, and a function that constantly raises the bottom of the toe of the footwear when walking with the force of the toes.

3. This trip prevention device can be linked to an obstacle warning and obstacle contact short-term device using proximity switches, making it useful for people with disabilities walking at night.
