Abstract

An earthquake shelter comprising a container sized for human occupancy, the container having walls and an access opening and a quickly openable and closable primary door to cover and uncover the opening, the container walls and door consisting of high strength panel material, in excess of 10,000 psi load resistance; the container supported for sliding movement compensating for earthquake induced movement of a supporting surface, with shock or impact absorbing cushioning means at the container interior, to cushion sudden movement of an occupant relative to the container as the container is suddenly moved by earthquake transmitted force.

Claims

exact text as granted — not AI-modified
1 . An earthquake shelter comprising:
 a) a container sized for human occupancy, the container having walls and an access opening and a quickly openable and closable primary door to cover and uncover said opening,   b) the container walls and door consisting of high strength panel material, in excess of 10,000 psi load resistance,   c) the container supported for sliding movement compensating for earthquake induced movement of a supporting surface,   d) shock or impact absorbing cushioning means at the container interior, to cushion sudden movement of an occupant relative to the container as the container is suddenly moved by earthquake transmitted force.   
     
     
         2 . The shelter of  claim 1  wherein said door is carried to manually slide open and closed at a side of the container. 
     
     
         3 . The shelter of  claim 2  including an air vent at one of the walls. 
     
     
         4 . The shelter of  claim 1  wherein panel material is selected from the group consisting of:
 i) DELRIN, 
 ii) KEVLAR, 
 iii) polycarbonate. 
 
     
     
         5 . The shelter of  claim 1  wherein said cushioning means comprises layers of insulative cushioning material applied to inner sides of said walls. 
     
     
         6 . The shelter of  claim 1  including a storage sub-container contained within the container, the sub-container having wall structure consisting of high strength panel material and being accessible to an occupant of the container. 
     
     
         7 . The shelter of  claim 1  wherein said support for sliding movement comprises low friction slider pads attached to the underside of the container. 
     
     
         8 . The shelter of  claim 1  wherein the shelter has elongated box configuration. 
     
     
         9 . The combination comprising upright building structures having rooms, the shelter located in one of said rooms to be quickly available to room occupants in the event of an earthquake. 
     
     
         10 . The combination of  claim 9  wherein the shelter has an outer upper surface serving as a furniture surface. 
     
     
         11 . The combination of  claim 9  including multiple of said shelters respectively located in multiple of said rooms. 
     
     
         12 . The combination of  claim 1  including a small window or windows provided in container walls enabling occupant viewing of building debris locations adjacent or spaced from the container, to provide for viewing of an escape path or route. 
     
     
         13 . The combination of  claim 1  including an openable and closable air vent in a container wall. 
     
     
         14 . The combination of  claim 1  including a secondary door provided in a wall opening defined by the container, and openable from the container interior, without diminishing container impact strength. 
     
     
         15 . The shelter of  claim 1  including one or more of the following stored in the container:
 i) communication equipment, 
 ii) a cell phone or phones, 
 iii) edibles, 
 iv) illumination equipment, 
 v) oxygen supply means. 
 
     
     
         16 . The shelter of  claim 1  wherein said walls are of sufficient thickness and size to withstand shock loads to be encountered during an earthquake. 
     
     
         17 . The shelter of  claim 9  wherein said walls are of sufficient thickness and size to withstand shock loads to be encountered during building destruction during an earthquake. 
     
     
         18 . The shelter of  claim 1  wherein said door is a first door at one wall of the container, there being a second door at a second access opening at another wall of the container. 
     
     
         19 . The shelter of  claim 7  including a container vertical movement damping means at one or more locations in the container. 
     
     
         20 . The shelter of  claim 19  wherein said dampening means includes a spring and functional damper
