Abstract
A vault for storing collectibles has a system for forcibly entering an incoming air, which after it has been filtered exits the vault along with undesirable substances trapped in a vault chamber.
Claims19
A vault for collectables, comprising:
- a housing provided with a vault chamber for storing the collectables;
- a filter mounted on the housing and operating so that when the filter is open, incoming air is guided along a path through the filter into the vault chamber while being purified, and when the filter is closed, incoming air is blocked from entering the vault chamber;
- a valve spaced downstream from the filter and mounted displaceably to the housing so that when the valve is open, the vault is in flow communication with outside, and when the valve is displaced in a closed position, the flow communication is blocked;
- and
- a vacuum source downstream from and in flow communication with the valve and operable for creating a pressure drop between the upstream and downstream of the path sufficient to force the incoming air through the filter into the vault chamber, where the purified air collects impurities as it exits through the open valve, the valve being displaced in the closed position upon closing the filter as the vacuum source continues to work to create a vacuum in the particle-free vault chamber.

A method for preserving collectible items from oxidation, comprising the steps of:
- (a) opening a filter;
- (b) providing an external vacuum source for generating pressure differential between an interior of a chamber and an outside, thereby forcing an ambient air into said filter;
- (c) simultaneously with step (b) filtrating the forced ambient air in said filter, thereby allowing a filtered air to collect impurities accumulated in the interior of the chamber and to exit therefrom through a valve located downstream from said filter;
- (d) controllably closing said filter while continuing to operate the external vacuum source thereby creating a vacuum in said chamber to prevent said stored collectibles from oxidation and deterioration;
- and
- (e) automatically closing said valve upon creating the vacuum in said chamber.
