  • Patent number: 11774087
    Abstract: A lamp for securing items has a pair of vertically separable enclosure portions joined by coiled flexible bands. The flexible bands are operated by an electro-mechanical drive to uncoil and to recoil, thereby first separating the enclosure portions and later rejoining them. A lower one of the enclosure portions has an interior storage space for receiving and securing items such as watches, cellphones, and wallets. The lamp is mounted on the bottom of the lower portion of the enclosure so as to direct its light beam downwardly. A control device enables remote operation of the drive and the lamp. The enclosure may be mounted to top trusses of a camping tent or canopy for instance. The camping tent or canopy may be left unoccupied with the assurance that a thief will not know that valuables are present in the lamp and also will not be able to gain access to the interior of the lamp.
