BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a shoe cushion, and more particularly to a shoe cushion for safety shoes.
2. Description of the Related Art
Aconventional shoe cushion20 in accordance with the prior art shown inFIG. 1 is used for one of a pair of safety shoes comprising ashoe body10 and ashoe sole15. Theshoe cushion20 is mounted on the top face of theshoe sole15 of theshoe body10. Theshoe cushion20 is made of hard metallic material to provide a protection effect to a user, thereby preventing the user's one foot from being hurt by a sharp object, such as a nail or the like. However, the shape of theshoe cushion20 is fixed and cannot be changed to correspond to the profile of the shoe sole of the shoe body and the profile of a user's one foot, thereby easily causing an uncomfortable sensation to the user when wearing the shoe.
SUMMARY OF THE INVENTION The present invention is to mitigate and/or obviate the disadvantage of the conventional shoe cushion.
The primary objective of the present invention is to provide a shoe cushion that has excellent mobility and provides a comfortable sensation to the user.
Another objective of the present invention is to provide a shoe cushion, wherein the combination pieces can be pivoted relative to each other so that the shape of the shoe cushion is changed freely so as to conform to the profile of the shoe sole of the shoe body and the profile of the user's one foot, thereby providing a comfortable sensation to the user wearing the shoe.
A further objective of the present invention is to provide a shoe cushion, wherein the shape of the shoe cushion is changed freely in one-dimensional or two-dimensional direction, so that the shoe cushion is bent freely to facilitate motion of the user's one foot.
In accordance with the present invention, there is provided a shoe cushion, comprising a plurality of combination pieces pivotally connected with each other, wherein each of the combination pieces has a first side formed with a pivot shaft and a second side formed with a pivot groove.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION Referring to the drawings and initially toFIGS. 2-6, ashoe cushion60 in accordance with the preferred embodiment of the present invention is used for one of a pair of safety shoes comprising ashoe body50 and ashoe sole55. Theshoe cushion60 is mounted on a top face of theshoe sole55 of theshoe body50. Theshoe cushion60 is made of hard metallic material to provide a protection effect to a user, thereby preventing the user's one foot from being hurt by a sharp object, such as a nail or the like.
In the preferred embodiment of the present invention, theshoe cushion60 comprises a plurality ofcombination pieces70 pivotally connected with each other. Thecombination pieces70 are juxtaposed to each other and arranged in a transverse manner. Each of thecombination pieces70 has a first side formed with a substantiallyconvex pivot shaft76 and a second side formed with a substantiallyconcave pivot groove78. Thepivot shaft76 of each of thecombination pieces70 has a periphery formed with two opposite tapered neck portions760. Thepivot groove78 of each of thecombination pieces70 has a periphery formed with two oppositetapered lip portions780.
As shown inFIGS. 4 and 5, thepivot shaft76A of afirst combination piece70A is inserted into and pivotally mounted in thepivot groove78 of an adjacentsecond combination piece70, and amovable gap79 is defined between each of the two oppositetapered neck portions760A of thefirst combination piece70A and the respectivetapered lip portions780 of thesecond combination piece70, so that thefirst combination piece70A and thesecond combination piece70 are pivotable relative to each other. Thus, thecombination pieces70 are pivotable relative to each other.
When in use, thefirst combination piece70A can be pivoted relative to thesecond combination piece70 as shown inFIG. 6. Thus, when theshoe cushion60 are subjected to bending force applied by theshoe sole55 of theshoe body50, thecombination pieces70 can be pivoted relative to each other so that the shape of theshoe cushion60 is changed freely in one-dimensional direction so as to conform to the profile of the shoe sole55 of theshoe body50 and the profile of the user's foot, thereby providing a comfortable sensation to the user wearing the shoe.
Referring toFIG. 7, theshoe cushion60 further comprises a plurality ofsecondary combination pieces75 pivotally connected with each other. Thesecondary combination pieces75 are juxtaposed to each other and arranged in a longitudinal manner. Preferably, thecombination pieces70 and thesecondary combination pieces75 are arranged in a staggered manner. Thus, the shape of theshoe cushion60 is changed freely in two-dimensional direction so as to conform to the profile of theshoe sole55 of theshoe body50 and the profile of the user's foot, thereby providing a comfortable sensation to the user wearing the shoe.
Referring toFIG. 8, thecombination pieces70 of theshoe cushion60 are integrally formed on theshoe sole55 of theshoe body50.
Accordingly, thecombination pieces70 can be pivoted relative to each other so that the shape of theshoe cushion60 is changed freely so as to conform to the profile of theshoe sole55 of theshoe body50 and the profile of the user's one foot, thereby providing a comfortable sensation to. the user wearing the shoe. In addition, the shape of theshoe cushion60 is changed freely in one-dimensional or two-dimensional direction, so that theshoe cushion60 is bent freely to facilitate motion of the user's one foot.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
