Abstract

A moveable footwear sole comprises an upper layer 1 and a lower layer 5 which are able to move independently of each other. Adjacent parts 2, 4 are positioned between the upper 1 and lower 5 parts of the sole, and interact to allow oscillatory sliding action of the sole parts 1, 5. Excessive movement is prevented by a damper system 3. In use, the chances of excessive pronation and supination within the subtalar joints of the foot is prevented through the use of the damper system 3 that controls the oscillatory sliding motion between adjacent parts 2 and 4 when specific forces are applied to the sole.

Description

Move footwear sole Physical activities that require change of movements such as cutting and turning heavily affect the rccking motion, pronation and supination, of the subtalar joints. This is focused within the lower extremity of the human body that may cause potential injuries. My invention decreases the chance of sustaining an injury within the subtalar joints, thus increasing the safety for users without limiting the natural movements of the human body.

My invention is a retrofitted design of the sole that includes two main parts, as shown in figure 1.

The first part is 1, which is a combination of la and lb as one whole component and 5, which is a combination of 5a and Sb as one whole component. 1 is the top layer of the sole and 5 is the bottom layer as show in figure 1. These parts support the function of the second main part of the invention.

The second part is 2, 3 and 4. These parts allow the function of my invention to take place. 2 is one component duplicated, as so is 4. 2 and 4 are the layers in between of 1 and 5 as show in figure 1. 2 is attached to lb and 4 is attached to Sb. 3 is attached to the outside of 1 and 5 as shown in figure 3.

Firstly, 2 and 4 are two adjacent parts that are not attached together but are in contact with each other as shown in figure 5. From the front and back angle, the bottom of 1 and the top of 5 are curved upwards in order to create a lateral oscillatory motion via 2 and 4, as shown in figure 4.

Shown in figure 4, the main function of 2 and 4 are that they allow a lateral oscillatory sliding motion to take place when pronation or supination occurs. 2 and 4 alsc provide a vertical oscillatory motion as shown from the design in figure 5, thus allowing further natural movements for the user. Providing an oscillatory motion decreases the angle of pronation and supination, thus decreasing the chances of sustaining an injury.

This oscillatory sliding motion is controlled by a damper (damping) system 3 as shown in figure 4.

The damper (damping) system 3 surrounds 2 and 4 but it is attached to 1 and 5, as shown in figure 3. 3 is attached to 1 and S because it does not allow any solid particles to gain contact with 2 and 4 as this will create friction between 2 and 4, thus decreasing the inventions intended oscillatory sliding motion. Another function of the damper (damping) system 3 is that it holds 2 and 4 together, hence why they cannot be vertically parted. Looking at 2 and 4 from the front angle as show in figure 5, the user will be restrained from sliding vertically forwards or backwards more than oscillating horizontally, left to right, when doing physical activities.

Figure 4 shows that when the bottom of the footwear S touches any surface, pronation or supination may occur within the subtalar joints. As 4 is attached to 5, the bottom of 5 will be gripped onto the surface the user is in contact with when providing the invention intended function, thus remaining its stature. Whereas, 2 and 1 will slide inwards or outwards in an oscillatory sliding motion 7 whilst being controlled by the damper (damping) system 3 to a gradual stop when the intended function of the invention is being carried out.

Therefore, the greater the force applied to the damper (damping) system 3, the greater the resistance and the turther the oscillatory sliding motion.

After 5 disembarks from the contacted surface or when the force applied from the user has stopped being applied, the damper (damping) system 3 will automatically re-align 2 and 4 together, as shown on figure 3.

From the side angles, 2 and 4 will be horizontally adjacent to each other with sequential gaps in between them as shown in figure 1. This then does not limit or restrict plantar flexion and dorsiflexion.

Secondly, 2 and 4 is accommodated in between 1 and 5 as shown in figure 3. 1 provides comfort, whereas 5 provides energy absorption, stability and grip when physical movement by the user or when 5 is in contact with any surface, thereby allowing the design to fulfil its intended function.
