Abstract

A lock box includes: a chassis; a lower housing solenoid attached to the chassis; a removable lower housing removably connected to the chassis through the lower housing solenoid; and a battery holder configured to removably secure a primary battery within the battery holder, such that the primary battery is configured to move with the removable lower housing, the primary battery being configured to provide electricity to the lower housing solenoid.

Claims (22)

1. A lockbox comprising:

a chassis;

a lower housing solenoid attached to the chassis;

a removable lower housing removably connected to the chassis through the lower housing solenoid; and

a battery holder configured to removably secure a primary battery within the battery holder, such that the primary battery is configured to move with the removable lower housing, the primary battery being configured to provide electricity to the lower housing solenoid;

wherein the removable lower housing further comprises a key storage area configured to retain at least one of a key or an access card therein;

wherein the removable lower housing further comprises a first housing side and a second housing side located opposite the first housing side, wherein the battery holder is located on the first housing side and the key storage area is located on the second housing side.

2. The lockbox of claim 1 , further comprising an outer cover attached to the chassis, the outer cover being configured to enclose the chassis, the lower housing solenoid, the removable lower housing, and the primary battery within the outer cover.

3. The lockbox of claim 1 , wherein the removable lower housing further comprises a first slot and a second slot, and

wherein the lower housing solenoid further comprises a first side, a second side opposite the first side, a first plunger is configured to project away from the first side to engage with the first slot, and a second plunger configured to project away from the second side to engage with the second slot.

4. The lockbox of claim 3 , wherein the removable lower housing further comprises a first column and a second column, wherein the first slot is located in the first column and the second slot is located in the second column.

5. The lockbox of claim 1 , wherein the removable lower housing further comprises a first electrical lead located within the battery holder, and wherein the primary battery is configured to electrically connect to the first electrical lead when the primary battery is located within the battery holder.

6. The lockbox of claim 1 , further comprising a second electrical lead attached to the chassis, wherein the primary battery is configured to electrically connect to the second electrical lead when the removable lower housing is secured to the chassis through the lower housing.

7. The lockbox of claim 6 , wherein the second electrical lead further comprises a contact spring and an attachment bracket.

8. The lockbox of claim 1 , further comprising:

a shackle solenoid, the primary battery being configured to provide electricity to the shackle solenoid; and

a shackle removably connected to the chassis through the shackle solenoid.

9. The lockbox of claim 8 , wherein the shackle further comprises a first prong, a first shackle slot located in the first prong, a second prong, and a second shackle slot located in the second prong, and

wherein the shackle solenoid further comprises a first solenoid side, a second solenoid side opposite the first solenoid side, a first shackle plunger is configured to project away from the first solenoid side to engage with the first shackle slot, and a second shackle plunger configured to project away from the second solenoid side to engage with the second shackle slot.

10. The lockbox of claim 9 , further comprising:

a backup battery configured to power the lower housing solenoid and the shackle solenoid when the primary battery is out of electricity.

11. The lockbox of claim 9 , wherein the backup battery is positioned within the chassis and outside of the removable lower housing.
