Abstract

A lightweight, collapsible foot pump made of a lightweight, collapsible material and filled with a foam like material which features large open cells to contain a large volume of air. The foam acting as a return spring for the pump.

1 . A light weight, collapsible air pump, comprising: an air pump enclosure made of a light weight, collapsible material and defining an interior region;
 a collapsible and expandable material generally filling said interior region, and adapted to contain a significant amount of air, said collapsible and expandable material serving as a spring for expanding said enclosure after it has been collapsed;   a fill a valve for allowing a air to quickly enter said interior region of said air pump enclosure when said air pump enclosure moves from a collapsed position to an expanded position; and   an air delivery port, fluidly coupled to said interior region of said air pump enclosure, for delivering air to an attached device when said air pump enclosure is collapsed.   
   
   
       2 . The air pump of  claim 1  wherein said collapsible and expandable material generally filling said interior region of said air pump enclosure includes foam. 
   
   
       3 . The air pump of  claim 1  wherein said air pump enclosure includes a bellows shaped fabric structure. 
   
   
       4 . A hard shell tent comprising:
 a first tent half and a second tent half, said first tent half attached to said second tent half proximit one a region of the circumference of both said first and second tent half;   first and second regions of said circumference of both said first and second tent halves proximate and extending from said attachment point each including a first and second tent half joining devices;   each of said first and second tent halves comprising first and second tent quarters, each first and second tent quarter coupled approximate one edge by a soft, flexible material, for allowing said first-quarter to fold onto said second quarter, and for said first half to fold on to said second half.   
   
   
       5 . The hard shell tent of  claim 4  wherein each tenant half has an elliptical shape. 
   
   
       6 . The hard shell tent of  claim 4  wherein said tent half joining devices include zippers. 
   
   
       7 . A tube like shelter comprising:
 a spiral spring-like frame structure, said spiral spring-like frame structure in the shape of the tube defining first and second openings; and   a flexible and collapsible fabric material covering said spiral, spring-like frame structure, for defining a tube having at least a first opening to be used as a shelter.   
   
   
       8 . A tent tie down loop comprising:
 A loop member having a first and a second end, said loop member divided into first and second sections, said first section being substantially larger than said second section, said first end of said first section attached to a tenant and comprised of a web like material; and   said second section formed of a weblike material forming a small pocket through which may be inserted in object to assist in holding down the tent, said weblike material of said second section formed with a twist so as to better engage with said object inserted therein.   
   
   
       9 . An ice screw comprising:
 Said ice screw comprising a shank portion and a handle portion; and   A mechanism for releasably coupling said handle portion to said shank portion, for allowing said handle portion to be repositioned vis-á-vis the axis of said shank portion so as to allow the user to rotate said handle portion and said shank portion and to releasably disengage said handle portion from said shank portion for reorienting said handle portion vis-á-vis the shank portion.   
   
   
       10 . The ice screw of  claim 9  wherein said mechanism includes a slide actuated switch. 
   
   
       11 . The ice screw of  claim 9  wherein said mechanism includes a ratchet mechanism. 
   
   
       12 . A mountaineering tool comprising:
 a head portion pivotably attached to a first end of a first shank portion;   a second shank portion pivotably coupled proximate a first end to a second end of said first shank portion; and   a handle portion pivotably coupled to a second end of said second shank portion.   
   
   
       13 . The mountaineering tool of  claim 12  wherein said head portion includes an ice pick. 
   
   
       14 . A tent comprising:
 a tent wall having a first portion and a second portion, said first portion including a region overlapping a corresponding region of said second portion; and   a strut mechanism, attached to one of said first or second portions, for maintaining an air ventilation space between said first portion and said second portion of said tent wall.   
   
   
       15 . A pivotable tent pole comprising:
 a first tent pole having a first and coupled to a tent pole pivoting device; and   a second tent pole having a first end coupled to said tent pole pivoting device, for allowing said first and second tent poles to pivot proximate their first ends relative to one another while maintaining said first and second tent poles in a fixed spaced relationship.   
   
   
       16 . A tent comprising:
 a tent material for forming a tent shelter, said tent material including at least one tent pole receiving pocket, for receiving a generally rigid tent pole for forming an opening in said tent material.   
   
   
       17 . The tent of  claim 16  wherein said tent material includes a plurality of tent pole receiving sockets, for receiving a plurality of generally rigid tent poles.
