ABSTRACT:

FIELD OF INVENTION
The present invention relates to a wheel rim and a seal member, and more particularly, to an improved wheel rim that may use or may not use with an inner tube.
BACKGROUND OF THE INVENTION
A conventional wheel that has an inner tube is shown in FIG.
1
and
FIG. 2
, and generally includes a circular rim
20
having a groove
201
defined in an outside of the rim
20
. The wheel rim
20
has two sidewalls between which the groove
201
is defined. A plurality of apertures
202
and a valve receiving hole
203
are radially defined through the rim
20
. A separating belt
24
is engaged with the groove
201
and a tire
21
is engaged with the wheel rim
20
by engaging two lips of the tire
21
with the two sidewalls of the wheel rim
20
. An inner tube
22
is received between the separating belt
24
and the tire
21
. A valve
221
connected to the inner tube
22
extends through a hole
241
in the separating belt
24
and the valve receiving hole
203
in the wheel rim
20
. Spokes
23
are engaged with the apertures
203
and are separated from the inner tube
22
by the separating belt
24
. Nevertheless, it is a trend to use a tube-less wheel in the market so that many efforts are made to improve the wheel rim designed for the use of inner tube into a wheel rim that can be used on a tubeless tire such as disclosed in Taiwanese published number 354530, 319180 and 239101. The disclosed wheel rims employ a seal member to seal the apertures for the spokes but the leakage problems still exist.
The present invention intends to provide a wheel rim that employs a rubber seal member whose two sides are put on a top of each sidewall and compressed by the tire so that there is a good seal feature between the rubber member and the rim and the tire.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a wheel and comprising a rim having two sidewalls and a groove is defined between the two sidewalls. A plurality of apertures and a valve receiving aperture are respectively defined through the rim. A seal member is located in the groove and has a hole defined therethrough. The hole is located in alignment with the valve receiving aperture. Two sides of the seal member are located on two respective tops of the two sidewalls of the rim. A tire is engaged with the groove and compresses the two sides of the seal member on the tops of the two sidewalls respectively.
The object of the present invention is to provide a wheel that has a seal member in a groove of a rim of the wheel, two sides of the seal member is compressed by a tire on two respective tops of two sidewalls of the rim. Therefore, the wheel can be used with an inner tube or without an inner tube.
These and further objects, features and advantages of the present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, several embodiments in accordance with the present invention.
