Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
243 words
An elastomeric glove adapted for pumping air over the wearer's hand when flexed comprising: a wrist portion, four finger portions, a thumb portion, a palm portion joining said finger, thumb and wrist portions to form a front face area of the glove, and a back portion joining said finger, thumb and wrist portions including a knuckle area extending from said finger portions toward said wrist portion; an outer panel of elastomeric material having the characteristic of independently returning to its original unstressed shape after being resiliently distorted, said panel being peripherally joined to the back portion in airtight condition and extending from said four finger portions and said thumb portion, the panel at said knuckle area being spaced from said back portion and in unstressed condition when the finger portions are extended to a straightened condition to form an air chamber with said back portion; valve means for controlling airflow between the outside and the air chamber; passages extending from the air chamber to the ends of the finger portions and the thumb portion; valve means for controlling airflow between the air chamber and the passages; said panel being resiliently distortable into a stressed condition upon bending the finger portions whereby air is pumped out of the air chamber, said panel on resiliently returning to its unstressed condition drawing air into the air chamber; said wrist portion allowing airflow between the outside and inside of the glove upon pumping and suction of air.

An elastomeric glove adapted for pumping air over the wearer's hand when flexed comprising: a wrist portion, four finger portions, a thumb portion, a palm portion joining said finger, thumb and wrist portions to form a front face area of the glove, and a back portion joining said finger, thumb and wrist portions including a knuckle area extending from said finger portions toward said wrist portion; an outer panel of elastomeric material having the characteristic of independently returning to its original unstressed shape after being resiliently distorted, said panel being peripherally joined to the back portion in airtight condition and extending from said four finger portions and said thumb portion, the panel at said knuckle area being spaced from said back portion and in unstressed condition when the finger portions are extended to a straightened condition to form an air chamber with said back portion; valve means for controlling airflow between the outside and the air chamber; passages extending from the air chamber to the ends of the finger portions and the thumb portion; valve means for controlling airflow between the air chamber and the passages; said panel being resiliently distortable into a stressed condition upon bending the finger portions whereby air is pumped out of the air chamber, said panel on resiliently returning to its unstressed condition drawing air into the air chamber; said wrist portion allowing airflow between the outside and inside of the glove upon pumping and suction of air.
Claim 3
Dependent Claim
39 words
An elastomeric glove as defined in claim 1, and wherein said first named valve means is an outlet valve means to the outside and is a swingable flap valve; and said second named valve means are swingable flap valves.
Claim 4
Dependent Claim
50 words
An elastomeric glove as defined in claim 1, and wherein said first named valve means is a blow-through vent valve to the outside and said second named valve means are swingable flap valves allowing air from the tips of the finger portions and the thumb portion to the air chamber.
Claim 5
Dependent Claim
58 words
An elastomeric glove as defined in claim 1, and wherein said first named valve means is a swingable flap valve allowing air entry from the outside on suction, and said second names valve means are blow-through valves formed by collapsible passages allowing airflow to the tips of the finger portions and the thumb portion from the air chamber.
Claim 6
Dependent Claim
159 words
In combination with a hand covering having at least one fingertip portion, means extending over the back panel of the hand covering including the fingertip portion and connected thereto to form an air chamber with the back of the hand covering, said means, at the knuckle area thereof, being resiliently biased to form a dome over the back of the hand covering when the wearer flexes his fingers to a straightened condition, thereby flattening the back of the hand covering, said panel being adapted to be forced toward a face-to-face engagement with the back when the wearer flexes his fingers toward a clenched condition, thereby bending the back of the hand covering and collapsing the air chamber to pump air; and valve means connecting said air chamber to the outside, and valve means connecting said air chamber to said fingertip portion, both said valve means limiting airflow in one direction between the outside and internally of the hand covering.
