Description
- This application claims the benefit of U.S. Provisional Patent Application No. 63/344,116, which was filed on May 20, 2022. The entire content of the foregoing provisional application is incorporated herein by reference.
- The inventions herein relate to structures, such as dwellings and other buildings for residential occupancy, commercial occupancy and/or material storage, and to components for such structures.
- In the field of residential housing, the traditional technique for building homes is referred to as “stick-built” construction, where a builder constructs housing at the intended location using in substantial part raw materials such as wooden boards, plywood panels, and steel columns. The materials are assembled piece by piece over a previously prepared portion of ground, for example, a poured concrete slab or a poured concrete or cinder block foundation.
- There have been a variety of efforts to depart from the conventional construction techniques used to create dwellings, as well as commercial spaces and like, in an effort to reduce costs. In this regard, a significant advancement is embodied in the Boxabl® foldable transportable dwelling unit, which consists of a number of enclosure components (four wall components, a floor component and a roof component), and portions thereof, which are dimensioned, positioned and folded together to form a
compact shipping module 15, as shown inFIG. 1A . The enclosure components and enclosure component portions are dimensioned so that theshipping module 15 is within applicable highway dimensional restrictions. As a result,shipping module 15 can be transported over a limited access highway more easily, and with appropriate trailering equipment, transported without the need for oversize load permits. Thus, the basic components ofstructure 150 can be manufactured in a factory, positioned and joined together to form theshipping module 15, and themodules 15 can then be transported to the desired site for the structure, where they can be readily deployed (unfolded) to yield a relatively finishedstructure 150, which is shown inFIG. 1B . - The process of unfolding the enclosure component and component portions of
shipping module 15 is often conducted with a mobile crane. Dispensing with the use of such a crane in many cases is desirable, both to simplify the deployment process as well as to facilitate deployment in situations where a mobile crane may not be readily available. - The present invention constitutes an advancement in means for deploying a foldable transportable structure.
- In a first aspect, the present invention is directed to a tool for the deployment of a foldable transportable structure comprising an elongate housing, an elongate threaded worm screw rotatably mounted to the elongate housing, a slider block defining both a threaded slider passage into which is threaded the worm screw and a slider pin aperture for receiving a slider unfolding pin, and means for constraining the slider block from rotating upon rotation of the worm screw, such that the slider block translates along the length of the worm screw upon rotation thereof. A first end of the elongate housing defines a housing pin aperture for receiving a housing unfolding pin. There is also provided means for applying torque to the worm screw to rotate the worm screw and cause the displacement of the slider block along the length of the worm screw relative to the housing.
- In some embodiments, the elongated housing can be a C-shaped channel. The tool can include a first guide rail and a second guide rail secured to inner sides of the elongated housing. The tool can include an end cap coupled to a first end of the elongated housing. The tool can include a first bearing disposed within an opening of the end cap and configured to receive a first end of the threaded worm screw. The tool can include a collar secured to the end cap to limit axial movement of the threaded worm screw and the first bearing. The tool can include a removable end cap cover configured to cover the first bearing and the collar. The tool can include a motor end cap fitted to a second end of the elongated housing. The tool can include a second bearing disposed within the motor end cap and configured to receive a second end of the threaded worm screw. The tool can include a removable motor end cap closure plate configured to limit axial movement of the threaded worm screw and the second bearing. The slider block can define a T-shaped configuration including a body and co-planar slider wings extending from opposing ends of the body. The threaded slider passage extends through the slider block in a direction perpendicular to the slider pin aperture. The tool can include a scissor assembly including two elongate bars each including a first end and a second end. The first end of each of the two elongate bars is hingedly joined together to the slider unfolding pin. The slider unfolding pin hingedly joins the first end of the two elongate bars to the slider block. The second end of each of the two elongate bars includes a bar end pin.
- In a second aspect, the present invention is directed to a method of constructing a folded building structure, where the folded building structure includes a building unit, a first enclosure member and a second enclosure member. The building unit, the first enclosure member and the second enclosure member each has a pin support affixed thereto for receiving an unfolding pin, and the first and second enclosure members are each joined in a folded position to the building unit and moveable with respect thereto. The method employs a tool comprising an elongate housing, an elongate threaded worm screw rotatably mounted to the elongate housing, a slider block defining both a threaded slider passage into which is threaded the worm screw and a slider pin aperture for receiving a slider unfolding pin. The tool includes means for constraining the slider block from rotating upon rotation of the worm screw, such that the slider block translates along the length of the worm screw upon rotation thereof, and a first end of the elongate housing defines a housing pin aperture for receiving a housing unfolding pin. The method comprises inserting a first end of a first unfolding pin in the pin support affixed to either the building unit or the first enclosure member, inserting a first end of a second unfolding pin in the pin support affixed to the second enclosure member, inserting a second end of the first unfolding pin in a first of the slider pin aperture or the housing pin aperture, inserting a second end of the second unfolding pin in a second of the slider aperture or the housing pin aperture, and rotating the worm screw.

transportable structure 150 in which the inventions disclosed herein can be implemented is depicted inFIGS. 1A-5 . When fully unfolded, as exemplified byFIG. 1B ,structure 150 has a rectangular shape made of three types of generally planar andrectangular enclosure components 155, the three types ofenclosure components 155 consisting of awall component 200, afloor component 300, and aroof component 400. As shown inFIGS. 1A, 1B and 2 , the perimeter ofstructure 150 is defined by firstlongitudinal edge 106, firsttransverse edge 108, secondlongitudinal edge 116 and secondtransverse edge 110. For convenience, a direction parallel to firstlongitudinal edge 106 and secondlongitudinal edge 116 may be referred to as the “longitudinal” direction, a direction parallel to firsttransverse edge 108 and secondtransverse edge 110 may be referred to as the “transverse” direction; and a direction parallel to the vertical direction inFIGS. 1A and 1B may be referred to as the “vertical” direction.Structure 150 as shown has onefloor component 300, oneroof component 400 and fourwall components 200; although it should be understood that the present inventions are applicable to structures having other configurations as well. - The
enclosure components 155 of the present invention include a number of shared design features that are described below. - A. Laminate Structure Design
-
Enclosure components 155 can be fabricated using a multi-layered, laminate design. A particular laminate design that can be used to fabricateenclosure components 155 is described in U.S. Non-Provisional patent application Ser. No. 17/552,108, entitled “Enclosure Component Fabrication Facility,” filed on Dec. 15, 2021. The contents of that U.S. Non-Provisional patent application Ser. No. 17/552,108, entitled “Enclosure Component Fabrication Facility,” filed on Dec. 15, 2021, are incorporated by reference as if fully set forth herein, particularly including the multi-layered, laminate designs described for example at ¶¶0027-0032 and depicted inFIG. 7 . - Other embodiments of multi-layered, laminate designs that can be used to fabricate the
enclosure components 155 of the present invention, are described in U.S. Non-Provisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures,” filed on Feb. 10, 2020 and now issued as U.S. Pat. No. 11,118,344. The contents of that U.S. Non-Provisional patent application Ser. No. 16/786,130, entitled “Foldable Building Structures with Utility Channels and Laminate Enclosures” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the multi-layered, laminate designs described for example at ¶¶0034-57 and depicted inFIGS. 4A-4D thereof. - B. Enclosure Component Exterior Edge Reinforcement
- The exterior edges of each enclosure component 155 (i.e., the edges that define the perimeter of enclosure component 155) can be provided with exterior edge reinforcement, as desired. Exterior edge reinforcement generally comprises an elongate, rigid member which can protect foam panel material that would otherwise be exposed at the exterior edges of
enclosure components 155. Exterior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the exterior edges ofenclosure component 155 with fasteners, such as screw or nail fasteners, and/or adhesive. - C. Enclosure Component Partitioning
-
Enclosure components 155 in certain instances are partitioned into enclosure component portions to facilitate forming acompact shipping module 15. In those instances where anenclosure component 155 is partitioned into enclosure component portions, any exterior edge reinforcement on the exterior edges defining the perimeter of the enclosure component is segmented as necessary between or among the portions. - The enclosure component portions can be joined by hinge structures or mechanisms to permit the enclosure component portions to be “folded” and thereby contribute to forming a
compact shipping module 15. - D. Enclosure Component Interior Edge Reinforcement
- An
enclosure component 155 partitioned into enclosure component portions will have interior edges. There will be two adjacent interior edges for each adjacent pair of enclosure component portions. Such interior edges can be provided with interior edge reinforcement. Similar to exterior edge reinforcement, such interior edge reinforcement generally comprises an elongate, rigid member which can protect foam panel material that would otherwise be exposed at the interior edges ofenclosure components 155. Interior edge reinforcement can be fabricated from one or more of laminated strand lumber board, wooden board, C-channel extruded aluminum or steel, or the like, and is generally secured to the interior edges ofenclosure component 155 with fasteners, such as screw or nail fasteners, and/or adhesive. - Further design details of
wall component 200,floor component 300, androof component 400 are provided in the sections following. - Typically,
structure 150 will utilize fourwall components 200, with eachwall component 200 corresponding to an entire wall ofstructure 150. - A. General Description
-
Wall component 200 has a generally rectangular perimeter. As shown inFIG. 1B ,wall components 200 have plural apertures, specifically adoor aperture 202, which has a door frame and door assembly, andplural window apertures 204, each of which has a window frame and a window assembly. The height and length ofwall components 200 can vary in accordance with design preference, subject as desired to the dimensional restrictions applicable to transport, described above. In this disclosure,structure 150 is fashioned with all sides of equal length; accordingly, its first and secondlongitudinal edges transverse edges wall components 200 are longer than the other two opposingwall components 200. - B. Partitioned Wall Components
- Referring to
FIG. 2 ,structure 150 has two opposingwall components 200, where one of the two opposingwall components 200 comprisesfirst wall portion 200 s-1 andsecond wall portion 200 s-2, and the other of the two opposingwall components 200 comprisesthird wall portion 200 s-3 andfourth wall portion 200 s-4. Each ofwall portions 200 s-1, 200 s-2, 200 s-3 and 200 s-4 has a generally rectangular planar structure. As shown inFIG. 2 , the interior vertical edge 192-1 ofwall portion 200 s-1 is proximate to a respective interior vertical edge 192-2 ofwall portion 200 s-2, and the interior vertical edge 194-3 ofwall portion 200 s-3 is proximate a respective interior vertical wall edge 194-4 ofwall portion 200 s-4. - Referring again to
FIG. 2 ,first wall portion 200 s-1 is fixed in position onfloor portion 300 a proximate to firsttransverse edge 108, andthird wall portion 200 s-3 is fixed in position onfloor portion 300 a, oppositefirst wall portion 200 s-1 and proximate to secondtransverse edge 110.First wall portion 200 s-1 is joined tosecond wall portion 200 s-2 with a hinge structure that permitswall portion 200 s-2 to pivot aboutvertical axis 192 between a folded position and an unfolded position, andthird wall portion 200 s-3 is joined tofourth wall portion 200 s-4 with a hinge structure to permitfourth wall portion 200 s-4 to pivot aboutvertical axis 194 between a folded position and an unfolded position. - Notably,
first wall portion 200 s-1 is longer thanthird wall portion 200 s-3 by a distance approximately equal to the thickness ofwall component 200, andsecond wall portion 200 s-2 is shorter thanfourth wall portion 200 s-4 by a distance approximately equal to the thickness ofwall component 200. Furthermore,wall portion 200 s-1 andwall portion 200 s-3 are each shorter in length (the dimension in the transverse direction) than the dimension offloor portion 300 a in the transverse direction. Dimensioning the lengths ofwall portions 200 s-1, 200 s-2, 200 s-3 and 200 s-4 in this manner permitswall portions 200 s-2 and 200 s-4 to nest against each other in an overlapping relationship when in an inwardly folded position. In this regard,FIG. 2 depictswall portions 200 s-2 and 200 s-4 both in their unfolded positions, where they are labelled 200 s-2 u and 200 s 4-u respectively, andFIG. 2 also depictswall portions 200 s-2 and 200 s-4 both in their inwardly folded positions, where they are labelled 200 s-2 f and 200 s 4-f respectively. Whenwall portions 200 s-2 and 200 s-4 are in their inwardly folded positions (200 s-2 f and 200 s-4 f), they facilitate forming a compact shipping module. Whenwall portion 200 s-2 is in its unfolded position (200 s-2 u), it forms withwall portion 200 s-1 awall component 200 proximate firsttransverse edge 108, and whenwall portion 200 s-4 is in its unfolded position (200 s-4 u), it forms withwall portion 200 s-3 awall component 200 proximate secondtransverse edge 110. - C. Unpartitioned Wall Components
- As compared to the two
wall components 200 proximate first and secondtransverse edges wall components 200 proximate first and secondlongitudinal edges wall components 200, which is sometimes denominated 200P in this disclosure, and which is located onfloor portion 300 b proximate firstlongitudinal edge 106, is pivotally secured tofloor portion 300 b to permitwall component 200P to pivot abouthorizontal axis 105 shown inFIG. 3 from a folded position to an unfolded position. Pivotally securingwall component 200P also facilitates forming acompact shipping module 15. The remainingwall component 200, sometimes denominated 200R in this disclosure, is rigidly secured onfloor portion 300 a proximate secondlongitudinal edge 116 and abutting the vertical edges offirst wall portion 200 s-1 andthird wall portion 200 s-3 proximate to secondlongitudinal edge 116, as shown inFIG. 2 . - Typically,
structure 150 will utilize onefloor component 300; thusfloor component 300 generally is the full floor ofstructure 150. - A. General Description
-
Floor component 300 has a generally rectangular perimeter. The length and width offloor component 300 can vary in accordance with design preference. In the particular embodiment ofstructure 150 depicted inFIGS. 1B and 2 ,floor component 300 is approximately 19 feet (5.79 m) by 19 feet (5.79 m). -
Floor component 300 and its constituent elements are generally designed and dimensioned in thickness and in other respects to accommodate the particular loads to whichfloor component 300 may be subject. - B. Floor Partitioning
- The
floor component 300 is partitioned intofloor portion 300 a andfloor portion 300 b.FIG. 2 shows flowportions floor portions floor portion 300 a adjoiningfloor portion 300 b. - Referring to structure 150 shown in
FIGS. 1B, 2 and 3 ,floor portion 300 a is fixed in position relative tofirst wall portion 200 s-1,third wall portion 200 s-3 andwall component 200R.Floor portion 300 a is joined with hinge structures tofloor portion 300 b, so as to permitfloor portion 300 b to pivot through approximately ninety degrees (90°) of arc about ahorizontal axis 305, generally located as indicated inFIG. 3 , proximate the top surface offloor component 300, between a fully folded position, wherefloor portion 300 b is vertically oriented as shown inFIG. 3 , and the fully unfolded position shown inFIG. 2 , wherefloor portion 300 b is horizontally oriented and co-planar withfloor portion 300 a. - Typically,
structure 150 will utilize oneroof component 400; thusroof component 400 generally is the full roof ofstructure 150. - A. General Description
-
Roof component 400 has a generally rectangular perimeter.FIG. 1B depictsroof component 400. The length and width ofroof component 400 can vary in accordance with design preference. In the particular embodiment ofstructure 150 depicted inFIGS. 1A, 1B, 2 and 3 , the length and width ofroof component 400 approximates the length and width offloor component 300. -
Roof component 400 and its constituent elements are generally designed and dimensioned in thickness and in other respects to accommodate the particular loads to whichroof component 400 may be subject. - B. Roof Partitioning
- The
roof component 400 ofstructure 150 is partitioned intoroof portions FIGS. 1A and 3 when folded, and inFIG. 1B when unfolded. Each of theroof portions roof portion 400 a adjoiningroof portion 400 b, androof portion 400 b adjoiningroof portion 400 c. - In the
shipping module 15 shown inFIG. 3 ,roof portions roof component 400 b stacked on top ofroof component 400 a, androof component 400 c stacked on top of theroof component 400 b. As can be appreciated fromFIG. 3 ,roof portion 400 a is fixed in position relative tofirst wall portion 200 s-1,third wall portion 200 s-3 andwall component 200R. Thus to realize the accordion folded configuration shown inFIG. 3 roof portion 400 a is joined toroof portion 400 b with hinge structures that are adapted to permitroof portion 400 b to pivot through up to one hundred and eighty degrees (180°) of arc about ahorizontal axis 405 a (seeFIG. 3 ) between the roof fully folded position shown inFIGS. 1A and 3 , whereroof portion 400 b lies stacked flat againstroof portion 400 a, and the fully unfolded position shown inFIG. 1B . In turn,roof portion 400 b is joined toroof portion 400 c with hinge structures that are adapted to permitroof portion 400 c to pivot through up to one hundred and eighty degrees (180°) of arc about ahorizontal axis 405 b (seeFIG. 3 ) between the folded position shown inFIGS. 1A and 3 , whereroof portion 400 c lies stacked flat againstroof portion 400 b (whenroof portion 400 b is positioned to lie flat againstroof portion 400 a), and the fully unfolded position shown inFIG. 1B . - Referring to
FIG. 2 ,structure 150 includes a fixedspace portion 102 defined byroof component 400 a (shown inFIG. 3 ),floor component 300 a,wall component 200R,wall portion 200 s-1 andwall portion 200 s-3. (Fixedspace portion 102 is also shown edge-on in theshipping module 15 depicted inFIG. 3 ). It is preferred that the fixedspace portion 102 be fitted out during manufacture with internal components, such as kitchens, bathrooms, closets, storage areas, corridors, etc., so as to be in a relatively finished state prior to shipment ofshipping module 15. Also, in the embodiment shown inFIGS. 1A, 1B and 2 ,wall components 200 are fitted during manufacture and prior to shipment with all necessary door and window assemblies, with theenclosure components 155 being pre-wired for electrical needs. - Carrying out the foregoing steps prior to shipment permits the builder, in effect, to erect a largely finished structure simply by “unfolding” (deploying) the positioned components of
shipping module 15. - It is preferred that there be a specific dimensional relationship among
enclosure components 155. -
FIG. 2 shows a top schematic view ofstructure 150 shown inFIG. 1B , and includes a geometrical orthogonal grid for clarity of explaining the preferred dimensional relationships among itsenclosure components 155. The basic length used for dimensioning is indicated as “E” inFIG. 2 ; the orthogonal grid overlaid inFIG. 2 is 8E long and 8E wide; notably, theentire structure 150 preferably is bounded by this 8E by 8E orthogonal grid. -
Roof portions FIG. 3 ,roof portion 400 c can be dimensioned to be larger than either ofroof portion 400 a androof portion 400 b in the transverse direction to reduce the chances of binding during the unfolding ofroof portions roof portion 400 c in the foregoing manner are described in U.S. Non-Provisional application Ser. No. 17/569,962, entitled “Improved Folding Roof Component,” filed on Jan. 6, 2022. In addition, as described in U.S. Non-Provisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” filed on Feb. 10, 2020 and now U.S. Pat. No. 11,220,816, as well as in U.S. Non-Provisional application Ser. No. 17/569,962 mentioned above, friction-reducing components can be used to facilitate unfoldingroof component 400, such as by positioning a first wheel caster at the leading edge ofroof portion 400 c proximate to the corner ofroof portion 400 c that is supported bywall portion 200 s-2 asroof portion 400 c is deployed, and by positioning a second similar wheel caster at the leading edge ofroof portion 400 c proximate to the corner ofroof portion 400 c that is supported bywall portion 200 s-4 asroof portion 400 c is deployed. - In
FIG. 2 , the fourwall components 200 are each approximately 8E long, and each ofroof portions Roof portion 400 c is approximately 8E long and 2.9E wide. InFIGS. 2 and 3 , each offloor components floor component 300 a is just over 3E wide andfloor component 300 b is just under 5E wide. - As shown in
FIG. 2 ,fourth wall portion 200 s-4 is folded inward and positioned generally against fixedspace portion 102, andsecond wall portion 200 s-2 is folded inward and positioned generally againstfourth wall portion 200 s-4 (wall portions 200 s-2 and 200 s-4 are respectively identified inFIG. 2 asportions 200 s-2 f and 200 s-4 f when so folded and positioned). The threeroof components FIG. 1B and shown folded (stacked) inFIG. 3 , withroof component 400 b stacked on top ofroof component 400 a, androof component 400 c stacked on top of theroof component 400 b.Wall component 200P, shown inFIGS. 2 and 3 , is pivotally secured tofloor portion 300 b at the location ofaxis 105, and is vertically positioned against the outside ofwall portions 200 s-2 and 200 s-4. In turn,floor portion 300 b is vertically positioned proximate fixedspace portion 102, withwall component 200P pending fromfloor portion 300 b betweenfloor portion 300 b andwall portions 200 s-2 and 200 s-4. - Sizing the
enclosure components 155 ofstructure 150 according to the dimensional relationships disclosed above yields acompact shipping module 15, as can be seen from the figures. Thus shippingmodule 15 depicted inFIG. 3 , when dimensioned according to the relationships disclosed herein using an “E” dimension (seeFIG. 2 ) of approximately 28.625 inches (72.7 cm), and when its components are stacked and positioned as shown inFIG. 3 , has an overall length of approximately 19 feet (5.79 m), an overall width of approximately 8.5 feet (2.59 meters) and an overall height of approximately 12.7 feet (3.87 meters). These overall dimensions are less than a typical shipping container. - Each of the wall, floor and
roof components shipping module 15. Alternatively or in addition, theentire shipping module 15 can be sheathed in a protective film. Such protective films can remain in place until after theshipping module 15 is at the construction site, and then removed as required to facilitate enclosure component deployment and finishing. - The
shipping module 15 is shipped to the building site by appropriate transport means. One such transport means is disclosed in U.S. Non-Provisional application Ser. No. 16/143,628, filed Sep. 27, 2018 and now U.S. Pat. No. 11,007,921, issued May 18, 2021; the contents of that U.S. Non-Provisional application Ser. No. 16/143,628, filed Sep. 27, 2018, are incorporated by reference as if fully set forth herein, particularly as found at paragraphs 0020-0035 and inFIGS. 1A-2D thereof. As an alternative transport means,shipping module 15 can be shipped to the building site by means of a conventional truck trailer or a low bed trailer (also referred to as a lowboy trailer), and in the case of over-the-water shipments, by ship. - At the building site,
shipping module 15 is positioned over its desired location, such as over a prepared foundation; for example, a poured concrete slab, a poured concrete or cinder block foundation, sleeper beams or concrete posts or columns. This can be accomplished by using a crane, either to liftshipping module 15 from its transport and move it to the desired location, or by positioning the transport means over the desired location, liftingshipping module 15, then moving the transport means from the desired location, and then loweringshipping module 15 to a rest state at the desired location. Particularly suitable equipment and techniques for facilitating the positioning of ashipping module 15 at the desired location are disclosed in U.S. Non-Provisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, now U.S. Pat. No. 11,220,816. The contents of that U.S. Non-Provisional patent application Ser. No. 16/786,315, entitled “Equipment and Methods for Erecting a Transportable Foldable Building Structure,” and filed on Feb. 10, 2020, are incorporated by reference as if fully set forth herein, particularly including the equipment and techniques described for example at ¶¶126-128 and in connection withFIGS. 11A and 11B thereof. - Following positioning of
shipping module 15 at the building site, the appropriate portions of wall, floor androof components structure 150. Unfolding occurs in the following sequence: (1)floor portion 300 b is pivotally rotated about horizontal axis 305 (shown inFIG. 3 ) to an unfolded position, (2)wall component 200P is pivotally rotated about horizontal axis 105 (the general location of which is shown inFIG. 3 ) to an unfolded position, (3)wall portions 200 s-2 and 200 s-4 are pivotally rotated aboutvertical axes 192 and 194 (shown inFIG. 2 ) respectively to unfolded positions, and (4)roof portions horizontal axes FIG. 3 ) respectively to unfolded positions. - Instead of using a mobile crane to assist in the deployment of certain sections of the enclosure components 155 (specifically
roof portions floor portion 300 b, as well as thewall component 200P pivotally secured tofloor portion 300 b), theuni-tool 500 of the present invention, depicted inFIGS. 4A-7 , can be utilized to deploy all of these enclosure component sections. - Referring to
FIGS. 4A and 4B ,uni-tool 500 includes an elongate C-Channel 501, twoopposed guide rails 502, anelongate worm screw 503, a T-shapedslider 504 and two bearings 506. The guide rails 502 are secured to the inner sides of C-channel 501 in any suitable manner, such as with adhesives or fasteners. C-channel 501 can be fabricated from grade 6061 aluminum, and optionally,guide rails 502 can be integrally fabricated with C-channel 501 in lieu of being separately fabricated.Worm screw 503 is provided with exterior screw threads along its length.Worm screw 503 can be fabricated from grade 4140 alloy steel. - As shown in

There is also provided a circularworm screw passage 513 through C-channel 501 (located in general terms at the head of the “T”). Theworm screw passage 513 is threaded to mate withworm screw 503 such that rotation ofworm screw 503 causesslider 504 to move along the length of C-channel 501. The body of the “T” ofslider 504 is provided with apin aperture 514, oriented orthogonally to the geometrical plane defined byslider wings 515, for receiving acylindrical pin 519. -
Motor end cap 509 shown inFIG. 6 can contain such components as are desired to facilitate the application of a suitable torque toworm screw 503 and thereby cause rotation. The source of the torque can be manually applied, such as by personnel turning a hand crank connected toworm screw 503 throughmotor end cap 509, geared as may be appropriate, or can be applied by utilization of motive power, such as an electric motor energized by a conventional 12-volt battery power source. In the embodiment shown,motor end cap 509 includes a first pulley 510-1 joined toworm screw 503 at its second end, below second bearing 506-2, and further includes a second pulley 510-2 rotationally mounted withinmotor end cap 509. The first and second pulleys 510-1, 510-2 are rotationally coupled by abelt 511. To achieve a desired amount of torque,belt 511 can include teeth that engage corresponding teeth provided about the circumferences of pulleys 10. The shaft of an appropriate source of motive power, such as an electric motor, can be inserted intocircular channel 516 ofmotor end cap 509 to engage second pulley 510-2 and rotateworm screw 503 when energized. - In use,
