2. Description of the Invention Background
Over the years, man has designed a variety of different shelter arrangements that are suited to satisfy particular needs and environmental conditions. For example, in some applications, it is desirable to have a shelter that is relatively portable and easy to erect. Perhaps one of the earliest of such shelters is the tent. While being relatively portable and easy to erect, tents have many shortcomings in that they are not particularly durable and are susceptible to damage by harsh weather and other environmental conditions. Moreover tents cannot typically be made secure.
In an effort to solve some of the shortcomings of tents, a variety of different portable shelters have been designed. Some of such shelters are constructed from components that are interconnected by hinges and may be moved from a folded position to an erected position. Examples of such shelters may be found in U.S. Pat. No. 3,103,709 to Bolt; U.S. Pat. No. 3,555,749 to Aitken; and U.S. Pat. No. 3,653,165 to West. Other structures have been designed such that their components are movable from a collapsed position to an expanded position. Examples of such structures are disclosed in U.S. Pat. No. 2,765,499 to Couse and U.S. Pat. No. 5,172,525 to Cook.
SUMMARYIn accordance with one embodiment of the invention, there is provided a collapsible shelter. One embodiment may include a lower shelter portion that has substantially rigid lower walls and a floor therein. An upper shelter portion that has substantially rigid upper walls and a roof is telescopingly coupled to the lower shelter portion such that the upper shelter portion is selectively vertically moveable relative to the lower shelter portion between a first collapsed position and a second extended position. In addition, the shelter may include a selectively releasable retainer assembly for selectively supporting the upper shelter portion relative to the lower shelter portion in the second extended position.
In accordance with another embodiment of the present invention, there is provided a collapsible shelter that may include a lower shelter portion and a sub floor structure that is attached to the lower shelter portion.

Third cable 360 then passes around a second pulley 374 that is attached to a cross brace 371 that is attached between floor braces 102 such that the axis of the second pulley 374 is substantially parallel to the axes of pulleys 372, 370. Third cable 360 passes around a third pulley 376 that is attached to the web 83 of rim 82 such that the axis about which the third pulley 376 rotates is substantially perpendicular to the axes of pulleys 372, 374. The third cable 360 extends through a passage 29 in wall 22 and out of the upper end of wall 22. Cable 360 passes between the exterior surface of wall 22 and the interior surface of wall 222. The other end of cable 360 is attached to the bottom of wall 222.
An end 382 of a fourth cable 380 is attached to a fourth cable adjustment device 382 that is attached to the carriage assembly 310. Fourth cable 380 extends around a central pulley 390 that is attached to a brace member 89. Fourth cable 380 is also journaled on a first pulley 392 that is mounted on a cross brace 391 attached to floor braces 102 such that the axis of the first pulley 392 is substantially parallel with the axis of central pulley 390. Fourth cable 380 extends around the first pulley 392 and is also journaled on a second pulley 394 that is attached to the web 85 of rim 84 such that the axis of second pulley 394 is substantially perpendicular to the axes of pulleys 390, 392. Fourth cable 380 extends through a passage 31 in wall 24 and out of the top of wall 24. Fourth cable 380 passes between the exterior surface of wall 24 and the interior surface of wall 224 and its second end is attached to the bottom end of wall 224.
The movement of the upper shelter portion 220 between extended and collapsed positions will now be explained with reference to
To move the upper shelter portion 220 to the extended position, the cylinder 302 is actuated to extend the piston 304 in the direction represented by arrow “I” in
The cable adjustment mechanisms 312, 314, 316, 382 provide a means for maintaining a desired amount of tension in each of the cables 320, 340, 360, 380 by enabling one to compensate for inadvertent stretching of the cables. In one embodiment, a removable panel is provided in the floor surface to enable easy access to the adjustment mechanisms. The reader will appreciate, however, that it is particularly advantageous to locate the lifting assembly 300 in the sub floor structure 80 to protect it from damage during transportation or sabotage in the field. It is conceivable, however, that lifting assembly could me located in other areas of the shelter 10 without departing from the spirit and scope of the present invention. In addition, while lifting system 300 employs four cables, it is conceivable that other numbers of cables and pulley configurations could be employed. For example, one or more cables could conceivably be used.
One or more embodiments of the present invention may also employ a locking assembly 400 to automatically retain the carriage assembly 310 in the extended position shown in
To move the upper shelter portion 220 to a collapsed position, the retainer lock 402 must be disengaged from the carriage assembly 310. In one embodiment, a release cable 420 is attached to the retainer lock 402. By pulling on the release cable 420, the retainer lock 402 is pivoted out of engagement with the carriage assembly to permit the carriage assembly to be moved in the “H” direction by actuating the cylinder 302.
In at least one embodiment of the present invention, cylinder 302 is actuated by a commercially available hydraulic pump 430 that is supported on the sub floor structure 80. As can be seen in
The arrangement of the access opening 440 under the lower door opening 30 in the lower shelter portion 20 provides other advantages. For example, as can be seen in
For ease of transportation and storage, the shelter 10 may be shipped to its final destination in the collapsed position. With the upper door segment 274 locked, unauthorized access to the pump is prevented. After the shelter 10 has been transported to a desired location, the user unlocks the lock 278 on upper door segment 274 and pivots the upper door segment 274 to the open position to gain access to the access door 442. See
To move the upper shelter portion to the collapsed position from the extended position, the user pulls on the release cable 420 and actuates the pump 430 to move the carriage assembly 310 in the opposing direction and thereby slacken cables 320, 340, 360, 380 to permit the upper shelter portion 220 to move to the collapsed position under the influence of gravity. Once the shelter 10 has been positioned in the collapsed position, the user closes the access door 442 and the upper door segment 274 and locks the upper door segment 274. The shelter is then ready to be transported to another location.
The reader will appreciate that various embodiments of the present invention may be actuated between the extended and collapsed positions without the use of tools. In the event that battery power is lost to pump 430, pump 430 may be of the type that can be manually actuated to manually extend the piston 304 of the hydraulic cylinder 302 to move the upper shelter portion to the extended position. A handle for manually actuating the pump 430 may be stored with the pump 430 inside the access opening 440. The battery or batteries 450 may be of the rechargeable type and be rechargeable by a solar power panel 460 that may be removably supported on the roof 240 or other portion of the shelter 10.
The various embodiments of the present invention may also provide a myriad of other advantages over prior shelter configurations. Various embodiments of the present invention, for example, are readily transportable with conventional material handling equipment such as forklifts and the like. The shelter embodiments may be advantageously sized to fit on conventional tractor-trailers and may be stacked on top of each other. The various embodiments of the present invention may also have a self-contained fresh water system complete with a sink, shower and toilet if desired. In addition, various embodiments may also be provided with a drain water holding tank for collecting drain water for eventual removal therefrom to a disposal truck or other medium for disposing and/or treating the drain water to prevent environmental contamination. Various embodiments of the present invention may also be actuated between the collapsed and extended positions without the use of tools.
Those of ordinary skill in the art will, of course, appreciate that various changes in the details, materials and arrangement of parts which have been herein described and illustrated in order to explain the nature of the invention may be made by the skilled artisan within the principle and scope of the invention as expressed in the appended claims.
