ABSTRACT:
A combination lock and pump having a shackle; a cross-member having a first end and a second end, the cross-member including a hole at the first end and a hole at the second end adapted to receive the shackle; a locking mechanism adapted to engage the shackle at the first end of the cross-member; a pump slidably engaging the cross-member at the second end of the cross-member, the pump having a pump shaft and a pump handle, the pump shaft including a hole to receive the shackle when the combination bicycle lock and pump is in a locked configuration; a connector for engaging an object to be pumped; a first one-way valve allowing air to enter the pump through the first one-way valve when the pump shaft is retracted from the pump and to prevent air from exiting the pump through the first one-way valve when the pump shaft is pushed into the pump; and a second one way valve preventing air from travelling into the pump from the connector but allowing air to be forced into the connector, wherein the shackle engages the cross-member and the pump when the combination bicycle lock and pump is in a locked configuration and wherein the pump forces air through the one-way valve into the connector when the pump is reciprocated within the cross-member.
