Tire insert for a tire of a model vehicle

Abstract

A tire insert for a tire of a model vehicle. The tire insert is made of a closed-cell foam and includes an outer surface, an inner surface, two perforated disk surfaces, and at least one cushioning cavity having at least one opening. The two perforated disk surfaces connect the outer surface with the inner surface. The at least one opening is arranged on one or on each of the two perforated disk surfaces so that the tire insert has a defined flexibility and/or an increased flexibility. The inner surface is substantially parallel to the outer surface so that the tire insert has a form of a hollow cylinder.

What is claimed is: 
     
         1 : A tire insert for a tire of a model vehicle, the tire insert being made of a closed-cell foam and comprising:
 an outer surface;   an inner surface;   two perforated disk surfaces, each of which are configured to connect the outer surface with the inner surface; and   at least one cushioning cavity comprising at least one opening, the at least one opening being arranged on one or on each of the two perforated disk surfaces so that the tire insert has at least one of a defined flexibility and an increased flexibility,   wherein,   the inner surface is substantially parallel to the outer surface so that the tire insert has a form of a hollow cylinder.   
     
     
         2 : The tire insert as recited in  claim 1 , wherein the at least one cushioning cavity is provided as a plurality of cushioning cavities. 
     
     
         3 : The tire insert as recited in  claim 2 , wherein each of the plurality of cushioning cavities is configured to have a substantially round cross-sectional area shape, a substantially oval cross-sectional area shape, or a substantially polygonal cross-sectional area shape. 
     
     
         4 : The tire insert as recited in  claim 2 , wherein each of the plurality of cushioning cavities are distributed along a circular curve on at least one of the two perforated disk surfaces. 
     
     
         5 : The tire insert as recited in  claim 2 , wherein,
 the two perforated disk surfaces each comprise several concentric, circular curves, and   the plurality of cushioning cavities are arranged on the several concentric, circular curves of at least one of the two perforated disk surfaces.   
     
     
         6 : The tire insert as recited in  claim 1 , wherein the at least one opening covers 2% to 50% of a surface of at least one of the two perforated disk surfaces. 
     
     
         7 : The tire insert as recited in  claim 1 , wherein the outer surface has a circumference of between 1.2 cm and 150 cm. 
     
     
         8 : The tire insert as recited in  claim 1 , further comprising:
 no air-filled chamber, or   one air-filled chamber, or   a plurality of air-filled chambers.   
     
     
         9 : The tire insert as recited in  claim 2 , wherein,
 each of the plurality of cushioning cavities has a central axis,   the tire insert has a central axis, and   the central axis of each of the plurality of cushioning cavities run parallel to the central axis of the tire insert so that each central axis of each of the plurality of cushioning cavities run parallel to each other.   
     
     
         10 : The tire insert as recited in  claim 1 , wherein,
 each of the plurality of cushioning cavities has a central axis,   the tire insert has a central axis, and   the central axis of each of the plurality of cushioning cavities run at an oblique angle to the central axis of the tire insert.   
     
     
         11 : The tire insert as recited in  claim 10 , wherein the central axis of each of the plurality of cushioning cavities run parallel to each other. 
     
     
         12 : The tire insert as recited in  claim 10 , wherein the central axis of each of the plurality of cushioning cavities run at an oblique angle to each other. 
     
     
         13 : A tire of a model vehicle comprising the tire insert as recited in  claim 1 . 
     
     
         14 : A model vehicle comprising the tire as recited in claim  claim 13 .
