U.S. Pat. No. 7,104,360 (Atkins) entitled “Mobile Elevating Hut” discloses a trailer mounted hut on pivoting support legs, which is raised and lowered by means of a winch.
- There is provided an elevated observatory which includes a frame and an observatory supported by the frame. Rigid travel guides extend upwardly from the frame providing a travel path. A drive system is provided for moving the observatory along the travel path provided by the travel guides to raise the observatory from a transport to an observation position.
- These and other features will become more apparent from the following description in which reference is made to the appended drawings, the drawings are for the purpose of illustration only and are not intended to in any way limit the scope of the invention to the particular embodiment or embodiments shown, wherein:
-
FIG. 1 is a side plan view of an elevated observatory in the transport position. -
FIG. 2 is a side plan view of the elevated observatory in an intermediate position. -
FIG. 3 is a side plan view of the elevated observatory in the observation position. -
FIG. 4 is a detailed side plan view of one side of the pivoting linkage of the elevated observatory. -
FIG. 5 is a detailed side plan view of the locking mechanism in the unlocked position. -
FIG. 6 is a detailed side plan view of the locking mechanism in the locked position. - An elevated observatory generally identified by
reference numeral 10, will now be described with reference toFIG. 1 through 6 . - Structure and Relationship of Parts:
- Referring to
FIG. 1 , elevatedobservatory 10 includes a frame that supports anobservatory 14. The frame may have different designs, such as part of a trailer, a skid, the bed of a truck, etc. In the description below, the frame is shown as part of atrailer 12. Observatory 14 is shown to be a type of cabin, however, it will be appreciated that it may be a platform, or may take other forms that would be practical for users such as bird watchers and hunters.Rigid travel guides 16 extend upwardly fromtrailer 12 and provide a travel path forobservatory 14.Trailer 12 hasoutrigger legs 17 that are extended prior to observatory being elevated.Travel guides 16 havebraces 15 to provide additional stability. Observatory 14 is designed to move along the travel path provided bytravel guides 16 such thatobservatory 14 is raised by a pivoting linkage, generally indicated byreference numeral 18, from a transport position shown inFIG. 1 to an observation position shown inFIG. 3 . A slidingclamp 19guides observatory 14 alongrigid travel guides 16.Rigid travel guides 16 includeaxial stops 21 toward the bottom ofguides 16, such that, in the transport position shown inFIG. 1 ,observatory 14 is supported byaxial stops 21. Observatory 14 may then be held in place againststops 21 using straps or other locking means to help keepobservatory 14 stable during transport. -
Pivoting linkage 18 has fourcollapsible observatory supports 20. Referring toFIG. 4 , each collapsibleobservatory support 20 has a trailer portion 22 (or, more generally, a frame portion) and anobservatory portion 24.Trailer portion 22 has afirst end 26 pivotally mounted totrailer 12 and asecond end 28.Observatory portion 24 has afirst end 30 pivotally mounted toobservatory 14, asecond end 32 pivotally connected tosecond end 28 oftrailer portion 22, and aguide rail 34 secured along the length of eachobservatory portion 24. There is also a pivotingframe 36 provided on each side ofobservatory 14. Eachpivoting frame 36 is pivotally connected betweentrailer portion 22 of the two adjacent collapsible observatory supports 20. Each pivotingframe 36 has liftingarms 38 withrail engaging ends 40. Eachrail engaging end 40 engages and travels along thecorresponding guide rail 34. Referring toFIG. 1 , awinch 42 is provided to apply a pulling force to pivot and draw together the twopivoting frames 36, such thatobservatory supports 20 are straightened, which causes observatory 14 to be raised through the intermediate position shown inFIG. 2 to the observation position shown inFIG. 3 . Referring toFIG. 3 ,observatory 14 is accessible in the observation position by aladder 45. Referring toFIGS. 1 and 2 ,ladder 45 folds with pivotingframe 36 to a collapsed state for travel whenobservatory 14 is in a transport position. - Referring to
FIGS. 5 and 6 , there is also provided alocking system 44 to lock thepivotal connection 46 betweensecond end 28 oftrailer portion 22 andsecond end 32 ofobservatory portion 24 to maintaintrailer portion 22 andobservatory portion 24 in a coaxial relationship.Pivotal connection 46 betweensecond end 28 oftrailer portion 22 andsecond end 32 ofobservatory portion 24 has an over-center stop position shown inFIG. 6 , while aresilient member 48 carried byobservatory portion 24 engagestrailer portion 22 to maintain thepivot 46 in the over-center position. For additional safety,locking system 44 may be designed such that arelease tool 50 is required to releaseresilient member 48. - Operation:
- Referring to
FIG. 1 ,trailer 12 is transported to a desired location with elevatedobservatory 10 in the transport position. Once properly positioned,outrigger legs 17 are extended to provide additional support toelevated observatory 10 in the observation position shown inFIG. 3 , and any straps or other locking means (not shown) used to stabilizeelevated observatory 10 are released. Once sufficiently prepared,winch 42 is activated such that a pulling force is applied towinch cables 43, which in turn causes pivotingframes 36 to pivot and be drawn together. It will be understood that other means may also be used to draw pivotingframes 36 together. For example, a separate winch may be used for eachcable 43, orwinch 42 may be replaced with a motor that turns a screw attached to each pivoting frame (not shown). Further variations will also be apparent to those skilled in the art. As pivoting frames 36 are drawn together, rail engaging ends 40 of liftingarms 38 travel along thecorresponding guide rail 34 to exert a lifting force ontrailer portion 22.Trailer portion 22 is thus caused to pivot from a substantially horizontal travel position shown inFIG. 1 , through the intermediate position shown inFIG. 2 and finally to the substantially vertical observatory supporting position shown inFIG. 3 . This in turn liftsobservatory portion 24 from a stored positioned shown inFIG. 1 , in which it is substantially parallel totrailer portion 22, to an observatory supporting position shown inFIG. 3 , in which it is substantially coaxial withtrailer portion 22. Referring toFIGS. 5 and 6 , astrailer portion 22 andobservatory portion 24 reach the substantially coaxial position,resilient member 48 of lockingsystem 44 locks them in place to help ensure thatobservatory 14 remains in the observation position. - Once it is desired to return
observatory 14 to the transport position, some slack is given tocables 43, and lockingsystems 44 are then released usingrelease tool 50. Referring toFIGS. 2 and 3 , once eachpivotal connection 46 has been taken out of the over-center position,winch 42 is reversed, such thatwinch cables 43 are played out, which allows pivotinglinkage 18 to return to the position shown inFIG. 1 . - In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
- It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiments without departing from scope of the Claims.
