Abstract

The present invention provides a simulated inflatable wheel including a rim, a filler tire mounted on the rim, and a tire casing covering the filler tire and having a rolling portion in rolling contact with the external environment and an abutting portion extending from two sides of the rolling portion. The abutting portion is located between the rim and the filler tire. The abutting portion abuts against the rim and the filler tire respectively. A recessed portion is formed on at least one position of an outer surface of the filler tire. The present invention utilizes the recessed portion of the filler tire to generate space between the filler tire and the rim (or the tire casing), for providing a buffer when the filler tire is deformed and improving elasticity of the filler tire. The present invention further provides a stroller including the simulated inflatable wheel.

First claim

What is claimed is:

1 . A simulated inflatable wheel comprising:
a rim; a filler tire mounted on the rim, the filler tire including a solid center core; and a tire casing covering the filler tire, the filler tire and the tire casing each being non-inflatable, and the tire casing having a rolling portion in rolling contact with an external environment and two abutting portions extending from two sides of the rolling portion respectively, the abutting portion being located between the rim and the filler tire, one side of the abutting portion abutting against the rim, another side of the abutting portion abutting against the filler tire; wherein a recessed portion is formed on at least one position of an outer surface of the filler tire, the recessed portion comprises:
a first recessed groove formed on one position where the outer surface of the filler tire is in contact with the tire casing;
a second recessed groove formed on another position where the outer surface of the filler tire is in contact with the tire casing; and
a third recessed groove formed on one position where the outer surface of the filler tire is in contact with the rim, wherein the first recessed groove, the second recessed groove, and the third recessed groove are each disposed symmetrically about a centerline of the rolling portion, with the centerline extending centrally through the third recessed groove.

2 . The simulated inflatable wheel of claim 1 , wherein a protruding portion extends from the filler tire toward the rim, and the third recessed groove is formed on a surface of the protruding portion.

3 . The simulated inflatable wheel of claim 1 ,
wherein the first recessed groove and the second recessed groove are located at two sides of the third recessed groove, respectively.

4 . The simulated inflatable wheel of claim 1 , wherein the first recessed groove and the second recessed groove are formed on positions where the outer surface of the filler tire is in contact with the rolling portion.

5 . The simulated inflatable wheel of claim 4 , wherein the first recessed groove and the second recessed groove are disposed adjacent to the two abutting portions, respectively.

6 . A stroller comprising:
a simulated inflatable wheel comprising:
a rim;
a filler tire mounted on the rim, the filler tire including a solid center core; and
a tire casing covering the filler tire, the filler tire and the tire casing each being non-inflatable, and the tire casing having a rolling portion in rolling contact with an external environment and two abutting portions extending from two sides of the rolling portion respectively, the abutting portion being located between the rim and the filler tire, one side of the abutting portion abutting against the rim, another side of the abutting portion abutting against the filler tire;
wherein a recessed portion is formed on at least one position of an outer surface of the filler tire, the recessed portion comprises:
a first recessed groove formed on one position where the outer surface of the filler tire is in contact with the tire casing;
a second recessed groove formed on another position where the outer surface of the filler tire is in contact with the tire casing; and
a third recessed groove formed on one position where the outer surface of the filler tire is in contact with the rim, wherein the first recessed groove, the second recessed groove, and the third recessed groove are each disposed symmetrically about a centerline of the rolling portion, with the centerline extending centrally through the third recessed groove.

7 . The simulated inflatable wheel of claim 6 , wherein a protruding portion extends from the filler tire toward the rim, and the third recessed groove is formed on a surface of the protruding portion.

8 . The stroller of claim 6 , wherein the first recessed groove and the second recessed groove are located at two sides of the third recessed groove, respectively.

9 . The stroller of claim 6 , wherein the first recessed groove and the second recessed groove are formed on positions where the outer surface of the filler tire is in contact with the rolling portion.

10 . The stroller of claim 6 , wherein the first recessed groove and the second recessed groove are disposed adjacent to the two abutting portions, respectively.
