Assignee:

AKALMP, Inc. - Indianapolis IN

International Classification:

F41B 1106

US Classification:

124 71, 124 74

Abstract:

An improved pressure regulator for pneumatic guns, with an improved and simplified design incorporating a rotating gas fitting with a gas inlet port; modular construction to allow fitting to different pneumatic guns/air sources/configurations; better pressure output stability at pressures lower than 200 psi; and improved ease of maintenance. There is also a sliding, externally actuatable check valve for pneumatically isolating one pneumatic component of the paintball gun from another pneumatic component.

US Classification:

124 72

Abstract:

An improved electronic pneumatic paintball gun, with an improved, simplified design incorporating an improved pneumatic hammer, electronic control circuit, pressure regulator, bolt design and cocking system for utilization in paintball guns or related devices. This paintball gun eliminates complex mechanical systems thus providing a consistent operation with low maintenance. The paintball gun utilizes low pressure to minimize damage to paint balls when fired and to the paintball gun's internal parts, plus increase the effective number of shots per tank.

US Classification:

49316, 160199, 494841, 277312

Abstract:

A moveable wall panel system is disclosed. The movable wall panel system may include a bottom drop seal assembly that maintains a constant force relative to a floor portion of an environment through a damper. The movable wall panel system may include an automatic top seal assembly that seals a gap between the movable wall panel system and a ceiling of the environment without an actuation from an operator space of the environment, the top seal assembly being positioned above the operator space of the environment. The moveable wall panel system may include a plurality of seals positioned between adjacent panels to seal a gap between the adjacent panels.

International Classification:

F41B11/00

US Classification:

124 73

Abstract:

A bolt-on air chamber that increases the volume of air stored inside a paintball gun. The increased volume of air allows the use of low pressure/high volume valves in the gun. The bolt-on air chamber also holds the gun together.

International Classification:

F41B 1132
F16K 100
F16K 112
F16K 3156

US Classification:

124 76

Abstract:

A valve, especially for use in a paintball gun which includes a pressure chamber bore for receiving gas from a source, an exhaust bore which leads to a barrel, and a valve chamber bore between the pressure chamber bore and exhaust bore. The valve includes a body mounted in the valve chamber bore with a flow path between the pressure chamber and exhaust bores, and a cupseal seat on the upstream side of the flow path. A valve stem passes through a portion of the flow path and is slidably supported by a support nose, and presents an actuation surface at one end, and supports a cupseal to mate with the seat at the other end. The cupseal has radial guide legs to closely and slidably contact the pressure chamber bore to aid alignment. The cupseal will normally be held against the seat by gas pressure and/or a spring; to open the valve, the gun may be provided with a hammer which is released to strike the actuation surface of the valve stem, to unseat the cupseal and allow gas to flow into the barrel.
