Description

Gait guiding device for shoes, sole comprising device and shoes

Technical Field

The invention relates to a gait guiding device for shoes, a sole comprising the device and a shoe comprising the sole.

Background

The walking process is a complex movement process, comprising a single support phase and a double support phase, wherein the single support phase generally refers to the process from the landing of the heel of the lower limb at one side to the separation of the toe at the same side, generally accounts for 40 percent of a walking cycle, and the process specifically comprises the following steps: the heel touches the ground, the full sole touches the ground, the gravity center is transferred to the same side, the heel lifts off the ground, the knee joint bends off, and the toe lifts off the ground. The bi-supportive phase refers to the process of bi-plantar support,

walking is a process in which a single support phase and a double support phase are mutually performed from a certain point of view, and the gravity center can also be considered to be a process in which the lower limbs on both sides alternately and continuously move forwards. Generally speaking, the center of gravity moves outwards due to the inertia of motion because the center of gravity interacts between lower limbs on both sides, so that the center of gravity does not move strictly along the center line of the sole when most people walk, but certain deviation or fluctuation is presented around the center line, and most soles are seriously worn eccentrically.

Referring to fig. 1 and 3, a gait guide for shoes according to an embodiment of the present invention includes a support beam 1 adapted to be inserted into a sole 6 along a length direction of the sole 6 and a lateral guide bar 2 intersecting the support beam 1, the support beam 1 having a length extending from a forefoot to a heel, the guide bar 2 being adapted to be inserted into the forefoot of the sole 6, and at least a portion of a center of the guide bar 2 being biased toward an outer side of the support beam 1. The support beam 1 and the guide bar 2 are generally made of an elastic material, the support beam 1 may have a similar curvature to the embedded shoe sole 6, the lateral guide bar 2 may be integrally formed with the support beam 1, the inner side of the support beam 1 refers to the side of the support beam 1 opposite to the other lower limb after being embedded in the shoe sole 6, and the outer side of the support beam 1 is the side opposite to the inner side. In this embodiment, the inertial impact caused by the shift of the center of gravity is mainly received by the outer side of the sole 6 when the single-strut and double-strut are inverted during walking, and thus the center of the partial guide rod 2 is biased to the outer side of the support beam 1 for guiding gait medially.

In the above embodiment, referring to fig. 1, the device has a plurality of guide rods 2, the adjacent guide rods 2 are spaced apart by a certain distance, and the distance between the outer ends 21 of the adjacent guide rods is greater than the distance between the inner ends 22, i.e. the plurality of guide rods 2 are distributed on the support beam 1 in a radial form. The guide rods 2 and the support beam 1 form a whole, when part of the guide rods 2 are bent and deformed, the guide rods 2 transmit bending stress to the support beam 1, the support beam 1 generates certain torsional strain, the support beam 1 transmits torsional moment to other guide rods 2, so that the whole device generates moment opposite to the direction, and when the double-support phase and the single-support phase are converted, the forepaw integrally guides the center of the human body to approach the center line.

In the above embodiment, referring to fig. 1, it further comprises a frame 3 adapted to be fixed to the edge of the shoe, the frame 3 is fixed to a support beam 1 by a support rod 4, the support beam 1 is disposed along the center line of the frame 3, and the support rod 4 is adapted to be inserted into the arch of the sole 6. The gait guide of the support beam 1 and the guide rod 2 to the half sole part leads the moment returning to the central line to be transmitted on the whole sole 6 through the frame 3, and the whole sole 6 generates the moment inwards so as to eliminate the tendency that the sole 6 turns outwards in the walking process. While the support bar 4 may serve to support the arch of the foot.

In the above embodiment, the frame 3 has a plurality of inward protrusions 31, so that the device is more tightly combined with the sole 6 when the device and the sole 6 are integrally formed by injection molding or the like, and the protrusions 31 can prevent the edge from being deformed too much to eliminate the tendency of the device to return to the center line after the edge is subjected to the force transmitted by the frame 3.

Generally, the heel is thick and hard, the heel is not easy to deform, the function of the support ring 5 alone for the heel is not obvious, in this embodiment, the inclined groove 11 is arranged on the heel, when the heel touches the ground, the deformation capacity of the heel after being stressed is improved, so that the groove has the function of guiding gait, and similarly, the groove is also disclosed in patent 201610316907.8, however, after the support ring 5 of the invention is used together with the inclined groove 11, the function can be enhanced, and when the heel is impacted by the outward inertia, the trend can be eliminated and the support force which can actively return to the inward direction can be provided.
