Appl. No.:

10/147894

Inventors:

James S. Zielinski - Schaumburg IL, US
Thomas C. Keenan - Franklin TN, US
Joseph E. Tyer - Lake Forest IL, US
Terrence P. Meier - Naperville IL, US

Assignee:

Illinois Tool Works Inc. - Glenview IL

International Classification:

F16K 15/20
B61D 45/00

US Classification:

137223, 137232, 141114, 141317, 410119

Abstract:

A cargo or dunnage air bag inflation and deflation system comprises an inflation-deflation valve member, a cap-type plug member, and an air gun implement having a fill nozzle and an exhaust nozzle mounted upon opposite ends thereof for respective connection to the valve member in order to perform inflation and deflation operations. The valve member comprises a flapper or check valve element pivotally mounted upon the valve member so as to permit inflation or deflation of the cargo or dunnage air bag when the flapper or check valve element is moved away from its valve seat, and to substantially maintain the cargo or dunnage air bag in its inflated state when the flappper or check valve element is effectively seated upon its valve seat. The cap-type plug member is removably mounted upon the inflation-deflation valve member so as to effectively close and seal the valve assembly when the cap-type plug member is mounted upon the valve member, and effectively uncovers the valve member when the cap-type plug member is dismounted from the valve member so as to permit the air gun implement to be operatively connected to the air valve member in order to perform an inflation or deflation operation.

International Classification:

B60P 715

US Classification:

410151

Abstract:

A cargo load bracing bar comprises first, outer and second, inner telescoping tubular members, a housing attached to the outer tubular member, a pinion gear and actuating ratchet handle, having a spring-biased ratchet member mounted thereon, respectively rotatably and pivotally mounted upon the housing, and a gear rack attached at one end thereof to the inner tubular member while the opposite end of the gear rack is slidably disposed upon the outer tubular member. An angle bracket is mounted upon the housing, and a spring-biased pawl member is slidably disposed upon the gear rack and operatively associated with the angle bracket. The pawl member and the ratchet member are normally engaged with the pinion gear so as to achieve the ratcheting extension of the gear rack and the inner tubular member with respect to the outer tubular member. However, the ratchet member may be disengaged from the pinion gear so as to permit the ratchet handle to be moved to a collapsed position substantially parallel to the outer tubular member, and both the ratchet member and the pawl member may be disengaged from the pinion gear so as to permit the pinion gear to freely rotate, and the gear rack and inner tubular member to undergo free longitudinal movement, so as to permit the cargo load bracing bar to be rapidly extended or contracted.

Appl. No.:

15/945265

Inventors:

- Glenview IL, US
Thomas A. Ketzer - Wauconda IL, US
Thomas C. Keenan - Brentwood TN, US

International Classification:

B60P 7/06
G05D 16/16

Abstract:

Various embodiments of the present disclosure provide a pneumatic inflator for automatically inflating inflatable articles, such as dunnage bags, to a desired pressure. Generally, once activated, the pneumatic inflator of the present disclosure inflates an inflatable article via a compressed air source until the air pressure inside the inflatable article reaches an operator-selected desired pressure. Thereafter, the pneumatic inflator automatically stops inflating the inflatable article. In various embodiments, the pneumatic inflator also includes a manual shut-off that, when activated while the pneumatic inflator is inflating the inflatable article, causes the pneumatic inflator to stop inflating the inflatable article. The pneumatic inflator of the present disclosure thus enables automatic inflation of inflatable articles to particular, operated-selected desired pressures with limited operator input.
