Abstract
A valve device attachable to a wheel including a tire in a state where the valve device penetrates through an opening of the wheel. The valve device includes a transmitter unit for detecting a condition of the tire and generating a transmission signal indicating the detected condition of the tire, a valve stem extending from the transmitter unit and an elastic member disposed to surround the valve stem. The elastic member has an annular attaching portion having a diameter greater than the diameter of the opening. The valve stem is attached to the wheel by passing the attaching portion through the opening by compressively deforming the attaching portion. The attaching portion includes a recessed portion for facilitating compressively deforming the attaching portion.
Claims19
A valve device for snap-attachment to a wheel including an opening having a diameter and a tire, the valve device comprising:
- a transmitter unit for detecting a condition of the tire and generating a transmission signal which indicates the detected condition of the tire;
- a valve stem extending from the transmitter unit;
- and
- an elastic member disposed to surround the valve stem, the elastic member including an annular attaching portion having a diameter greater than the diameter of the opening, in which the valve stem is attachable to the wheel with the attaching portion attached to a portion of the wheel around the opening by compressively deforming the attaching portion and passing it through the opening, the attaching portion including a recessed portion for facilitating compressively deforming the attaching portion.
A valve for snap-attachment to a wheel including an opening and a tire, the valve device comprising:
- a transmitter unit for detecting a condition of the tire and generating a transmission signal which indicates the detected condition of the tire;
- a valve stem extending from the transmitter unit;
- an elastic member disposed to surround the valve stem, wherein the valve stem is attached to the wheel by engaging the elastic member with the opening and wherein the elastic member is removable with respect to the valve stem.
A valve for snap-attachment to a wheel including an opening and a tire, the valve comprising:
- a transmitter unit comprising a casing and a transmitter module detachable with respect to the casing, the transmitter module including an electronic component for detecting a condition of the tire and generating a transmission signal indicating the detected tire condition and a battery for supplying electricity to the electronic component;
- a valve stem extending from the casing;
- and
- an elastic member disposed to surround the valve stem, wherein the valve stem is attachable to the wheel by engaging the elastic member with the opening.
