Abstract
Description
- The invention relates to a shock absorber for use in a heel section of a shoe.
- In order to improve comfort of a shoe for a wearer, it is known in the art to provide a heel section of the shoe with a shock absorber for relieving the pressure on the wearer's feet.
- Whether a person is running, walking or even just standing still, a substantive force acts on her feet, and in particular on her heels, where a major part of the body weight is balanced. This is even more evident in case the person stands on a hard surface, such as concrete, which is often the case in e.g. industrial environments. This can ultimately lead to back and knee injuries.
- When comparing elasticity of the up to 2 cm thick fibrofatty body tissue located under the heel bone of a population of individuals, the degree of elasticity may vary up to 50% for two given individuals in the population. Further, the elasticity of an individual's heel tissue is not the same at an outer part of the heel as compared to a heel centre part. A problem with shock absorbers in the art is that they are not adapted to this varying elasticity in heel tissue.
- An object of the present invention is to solve or at least mitigate this problem in the art and to provide an improved shock absorber.
- This object is attained in a first aspect of the present invention by a shock absorber for use in a heel section of a shoe. The shock absorber comprises a first elastic member having a first elasticity and a second elastic member having a second elasticity, which second elastic member is arranged to be integrated with the first elastic member, wherein the second elastic member has a greater elasticity than the first member.
- Thus, by providing the shock absorber according to embodiments of the present invention, it is possible to advantageously adapt to different elasticity properties of the heel tissue of an individual, and further to adapt to varying elasticity properties among a population of individuals.
- In an embodiment of the present invention, the second elastic member is arranged at a center of the first elastic member. Thus, when in use, the second elastic member will be compressed to a higher degree than the first member due to its greater elasticity. By arranging the second elastic member at the center of the first elastic member, the shock absorber according to this embodiment will become bowl-shaped around the heel of the wearer of the shoe in which the shock absorber is arranged and thus advantageously improve the comfort of the wearer.
- In an embodiment, the first elastic member has a Shore A value of approximately 20 and the second elastic member having a Shore A value of about 10. Thus, the hardness of the first elastic member is about twice that of the second elastic member. It should be noted that the respective hardness of the first and second elastic member may take on other Shore A values than these two. Generally, the shock absorber of the present invention is positioned between the relatively soft heel of a wearer of a shoe and the hard surface underneath the shoe. Thus, the second elastic member is slightly softer than the body tissue surrounding the heel while the first elastic member is slightly harder.
- The shock absorber according to the present invention can be made of e.g. polyurethane plastics such as thermoplastic polyurethane (TPU) or thermoplastic rubbers (TR).
- In a further embodiment, the second elastic member is arranged to be selectively removable from the first elastic member. Thus, since the wearer can insert and remove the second elastic member from the first elastic member, the elasticity of the shock absorber can be even further adapted to the individual wearer in that second elastic members having different measures of hardness may be inserted in the first elastic member at a choice of the individual wearer.
- The object of the invention is further attained in a second aspect by an insole comprising the shock absorber of the first aspect.
- The object of the invention is further attained in a third aspect by a shoe comprising the insole of the second aspect.
- It is noted that the invention relates to all possible combinations of features recited in the claims. Further features of, and advantages with, the present invention will become apparent when studying the appended claims and the following description. Those skilled in the art realize that different features of the present invention can be combined to create embodiments other than those described in the following.

Figure 1 shows a perspective view of a prior art shock absorber 10 to be arranged in a heel section of a shoe. As can be seen, the shock absorber comprises awaist part 11 around which a insole (not shown) will be tightly arranged in order to create a locking engagement with theshock absorber 10. Further, theshock absorber 10 comprises atop part 12 extending radially from thewaist part 11 and abottom part 13 on which the shock absorber rests, which bottom part extends radially from the waist part. When arranged at the heel section of a shoe, an inlaysole (not shown) is placed on thetop part 12. Further, the prior art shock absorber 10 comprises a plurality ofcavities 14 extending from thetop part 12 through thewaist part 11 and in to thebottom part 13. The shock absorber is made of an elastic material, typically rubber. -
Figures 2a-d show the shock absorber 10 in a section taken along line A-A ofFigure 1 in different degrees of deformation.Figure 2a shows a cross section of the shock absorber when no force is applied to thetop part 12.Figure 2b illustrates the elasticity of the shock absorber 10 when a force F is applied to thetop part 12. In use, this force will be embodied by the weight of a wearer of the shoe.Figures 2c and 2d show deformation of the shock absorber as the force F applied by the wearer's heel to thetop part 12 increases. The deformation is further facilitated by thecavities 14. The elasticity of the prior art shock absorber 10 greatly improves the comfort of the wearer of the shoe in which the shock absorber is arranged. -
Figure 3 shows a perspective view of a shock absorber 20 to be arranged in a heel section of a shoe according to an embodiment of the present invention. According to the invention, the shock absorber 20 comprises a firstelastic member 25 having a first elasticity and a secondelastic member 26 having a second elasticity, which second elastic member is arranged to be integrated with the first elastic member, wherein the second elastic member has a greater elasticity than the first member. Thus, when a force F is applied to the shock absorber 20 of the present invention, as is discussed in connection to the prior art shock absorber 10 shown inFigures 2a-d , the shock absorber 20 of the present invention will be even more compressed at its centre, where the softer secondelastic member 26 is arranged. -
Figure 4 shows a top view of the shock absorber 20 according to embodiments of the present invention, illustrating that the secondelastic member 26 is arranged at the centre of the firstelastic member 25. - Again with reference to
Figure 3 , it can be seen that the shock absorber 20 according to an embodiment of the present invention comprises awaist part 21 around which a insole (not shown) will be tightly arranged in order to create a locking engagement with theshock absorber 20. Further, theshock absorber 20 comprises atop part 22 extending radially from thewaist part 21 and abottom part 23 on which the shock absorber rests, which bottom part extends radially from the waist part. When arranged at the heel section of a shoe, an inlaysole (not shown) is placed on thetop part 22. In an embodiment, thetop part 22 extends further in a radial direction than thebottom part 23, thus acting as a gasket against an upper side of the insole (not shown) in which the shock absorber is arranged. -
Figure 5a shows a sectional view of theshock absorber 20 according to an embodiment of the invention arranged in the heel section of aninsole 30. As can be seen, the height of thewaist part 21 is adapted to the thickness of theinsole 30. Further, thebottom part 23 and thetop part 22 are arranged to sandwich theinsole 30 which encloses thewaist part 21 in order to retain theshock absorber 20 in locking engagement with the insole. As can be seen, the secondelastic member 26 is positioned in a cavity of thewaist part 21. -
Figure 5b shows a sectional view of theshock absorber 20 and theinsole 30 ofFigure 5a when mounted in ashoe 40 according to an embodiment of the present invention. As can be seen, aheel section 41 of theshoe 40 is arranged with anaccommodation 42 for receiving and housing thebottom part 23 of theshock absorber 20. -
Figure 6 shows a top view of theinsole 30 ofFigure 5 , in which theshock absorber 20 of the present invention is arranged, which shock absorber comprises the firstelastic part 25 and the secondelastic part 26. As can be deducted fromFigure 6 , when a wearer of a shoe (not shown) in which theinsole 30 is arranged places her heel on theshock absorber 20, the centre part of her heel will press the secondelastic member 26 in a direction towards the surface on which the shoe rests, and the secondelastic member 26 will be compressed to a higher degree than the firstelastic member 25 due to its greater elasticity. Thus, theshock absorber 20 of the present invention will adapt to the elasticity of the body tissue located under the heel bone of the foot. -
Figure 7 shows yet another embodiment of the present invention where the secondelastic member 26 is arranged to be selectively removable from the firstelastic member 25. The shock absorber according to an embodiment of the invention has in itstop part 22 anopening 27 through which the secondelastic member 26 is inserted into thecavity 28 of the waist part. Thus, since the wearer can insert and remove the secondelastic member 26 from the firstelastic member 25, the elasticity of the shock absorber can be even further adapted to the individual wearer in that second elastic members having different measures of hardness may be inserted in the first elastic member at a choice of the individual wearer. - With further reference to
Figure 7 , in an embodiment of the present invention thetop part 22 of thefirst member 25 comprises aflange 29 arranged at a circumference of theopening 27 trough which the secondelastic member 26 is inserted into thecavity 28 of the waist part. Advantageously, theflange 29 facilitates retention of thesecond member 26 in thecavity 28. - In yet another embodiment of the present invention, the
cavity 28 in the waist part has a bottom section arranged with openings to a plurality ofcavities 24 extending into the bottom part, where each cavity is separated from adjacent cavities by acorresponding wall member 30. As was described with reference toFigure 2 , thecavities 24 will facilitate deformation of the chock absorber when acted upon by a compressing force. -
Figures 8a-d shows theshock absorber 20 according to embodiments of the present invention in a section taken along line B-B shown inFigure 4 in different degrees of deformation.Figure 8a shows a cross section of theshock absorber 20 when no force is applied to thetop part 22.Figure 8b illustrates the elasticity of theshock absorber 20 when a force F is applied to thetop part 22. In use, this force will be embodied by the weight of a wearer of the shoe.Figures 8c and 8d show deformation of theshock absorber 20 as the force F applied by the wearer's heel to thetop part 22 steadily increases. The elasticity of theshock absorber 20 of the present invention greatly improves the comfort of the wearer of the shoe in which the shock absorber is arranged. Further, as compared to the priorart shock absorber 10 shown inFigures 1 and 2 , due to the secondelastic member 26 having a greater elasticity than the firstelastic member 25, theshock absorber 20 of the present invention will be more compressed at its centre section where a majority of the force F is applied, thus creating a bowl-like support around the heel of the wearer. - Even though the invention has been described with reference to specific exemplifying embodiments thereof, many different alterations, modifications and the like will become apparent for those skilled in the art. The described embodiments are therefore not intended to limit the scope of the invention, as defined by the appended claims.
