Description
PORTABLE COLLAPSIBLE BUILDING STRUCTURE
Technical Field
This invention relates to pre-fabricated collapsible structures and, more specifically, to a portable collapsible building, which may be easily transported, and quickly assembled.
Background Art
There is a number of pre-fabricated portable collapsible building structures designed, which may be transported by a truck and erected on- site to provide a temporary accommodation, storage or service facility building.
There is known a collapsible container (patent US 4577772 "Collapsible containers", Int. Cl.4 B65D 7/26, granted 25.03.1986) comprising opposite sidewalls each having a medial hinge joining two panels to permit inward folding of the sidewalls with simultaneous collapsing of the top and bottom sections which are pivotally attached to respective edges of the sidewalls. This pivotal attachment is provided by hinge assemblies including cooperating U-shaped plates shiftable to allow both maintenance of a rigid expanded container and also permit the collapse thereof. End door members include pivotal attachment devices which may include roller elements to allow displacement of the end door members from an end closing position to a position disposed parallel with and underlying the top section. For unlocking the sidewalls, the top section must be lifted so that the U-shaped plates are separated from the enclosure and the sidewalls can be unfolded after retracting the door members of the container toward the top section. This operation is performed with cranes or equivalent conventional equipment gripping the top section at its edges.
There is also known a portable building (WO91/02869 "Portable building", Int. Cl.5 E04H 1/12, published 07.03.1991) having a floor, a roof, side walls and end walls, said end walls being pivotally connected at the ends of the buildings so that they can pivot from an upright position to a generally horizontal position, said side walls comprising at least two portions coupled together by a generally central hinge which extends the entire length of the side wall, one of said portions being pivotally coupled to an upper portion of the building by a hinge and the other of said portions being pivotally coupled to a lower portion of the building by a hinge such that said side wall can collapse inwardly so that
said portions are substantially parallel with said roof and said floor. The said end walls include locking means for locking the end walls to the side walls when the building is in the erected position. The known portable building can be erected on site by raising roof to enable side wall portions to pivot into an upright position and end walls can be pivoted from a collapsed substantially horizontal position into an upright position at the ends of the building. The building is provided with wiring within the side walls, end walls and roof to enable electric power to be supplied to the building. Similar solutions are disclosed in FR 2388098 and FR 2846985.
The main drawback of the known collapsible container and portable buildings is that special machinery, such as crane or the like is required for assembling these portable buildings. During assembling of the known collapsible portable structures, when its roof and walls are being raised by the crane or other machinery, a person has to enter inside the collapsible portable structure, put the end walls into the vertical position and activate locking or engaging means to keep the walls in the assembled position. The collapsible portable structure becomes stable only after putting the end walls into the vertical position and activating the locking or engaging means. Therefore there is a time interval, while assembling the collapsible portable structure, during which a person's safety is especially endangered. Moreover, assembling of the known collapsible portable structures must not be performed when it is windy or during seismic activity, because heavy machinery may damage the collapsible portable structure or injure erectors.
Other inventors suggest solution to overcome this drawback by providing a collapsible building which may be assembled by a single operator (WO 89/07180 "Collapsible structure", Int. Cl.4 E04B 1/34, published 10.08.1989). The known collapsible building comprising: a floor structure; a roof structure; a pair of opposite side walls pivotally connected to said floor structure and said roof structure, each side wall being comprised of a pair of half sections pivotally connected together; and, a pair of opposite end walls, pivotally connected to said floor structure, each end wall being comprised of a pair of half sections pivotally connected together; such that, in a collapsed state, said side walls, said end walls, said floor structure and roof structure lie in substantially co-planar relationship, one on top of the other, and, in an erected position, each of said half sections of each of said walls lie in end abutting relationship in a substantially perpendicular relationship to each of said floor structure and said roof structure. At least one securement cable is provided in a corresponding through hole formed in each half section in each side
wall and in an abuting portion of the roof structure and floor structure adjacent thereto, such that, after erection of the building, said securement cable may be tightened and secured to maintain said side wall in a substantially vertical position by preventing pivotal movement of the pivots provided between the two half sections, the roof structure and the floor structure. The collapsible building is provided with hoist post for use in assembling the building, said hoist post comprising: a longitudinally extending post provided with a longitudinally extending slit therethrough; an attachment means for affixing a lower end of said post to a base member of said structure or building whilst allowing pivotal movement thereabouts; a winching device, also provided at substantially the lower end of said post; a guide or pulley means provided at substantially an upper end of said post on the opposite side of said post to said winching device; and, a cable, a first end of said cable adapted to be attached to said structure of building to be raised, said cable then passing via said slit, over said guide or pulley and via said slit to said winching device, such that, upon rotation of said winching device, said cable consequently raises said structure or building attached to the first end thereof.
In case all four walls are foldable as suggested, the regular doors cannot be preinstalled in the known collapsible building. This makes the known building less suitable for use in situations when time of assembling is significant. The main drawback of the known collapsible building is that its construction, in particular, construction of its means for raising the elements of the building and means for maintaining the walls in a substantially vertical position while being quite complicated, is not sufficiently reliable. The known collapsible building comprise quite big number of swivel joints, that limits the lifetime of the building and makes it less stable. The means for maintaining the walls in a substantially vertical position comprise a securement cable, which is fixed at sharp angle and holds on-loading the elements of the building. The known means for maintaining the walls in a substantially vertical position do not withstand such load for a long time especially in windy regions; thus endangering stability of the building and public safety.

With reference to Figures 1, 3, 7 and 9, the portable collapsible building structure 1 comprises a floor member 2, a roof member 3, side walls 4 and end walls 5. The side walls 4 comprise at least and preferably two pivotally connected side wall sections 6 and 7, the sections 6 being pivotally coupled to the roof member 3 and the other of the sections - 7 being pivotally coupled to the floor member 2 such that the side walls 4 can collapse inwardly so that the side wall sections 6 and 7 are substantially parallel with the floor member 2 and the roof member 3. The end walls 5 being pivotally and slidably connected at the ends of the floor member 2 and adapted to be folded inwardly from an upright position to generally horizontal position and vice versa (as shown in figures 1, 3, 4, 6 and 8), as well as slid (in and out) in the floor member's 2 longitudinal direction (as shown in figures 1, 2, 4 and 5). The means for pivotal and slidable connection of the end walls 5 at the ends of the floor member 2 comprise:
- sliding pipe 8, which is fixed to the end wall 5 (preferably to at least one member of the end wall's 5 frame),
- sliding pipe 8 guide bar 9 being inserted into the sliding pipe 8 and provided with upper and lower sliding pipe 8 stoppers 10 so that the sliding pipe 8 has the ability to slide between them on guide bar 9,
- guide bar 9 support arm 11 having first and second end, the first end of the support arm 11 being fixedly connected to the floor member 2 (preferably to a member of the floor member's 2 frame) and the second end of the support arm 11 being hingedly connected to the guide bar 9 so that when the building structure 1 is in a collapsed condition, the guide bar 9 has the ability to be put from the vertical into the horizontal position and backwards bringing the end wall 5 into the folded position (towards the centre part of the roof member 3) and unfolded (upright) position.
The upper and lower stoppers 10 are mounted so that the sliding pipes 8 and the end walls 5 being fixed to them have the ability to be slid in towards the centre of the building structure 1 so that base 12 of the end wall 5 is in one plane with vertical plane of the shorter side of the floor member 2; and slid out to the distance, which is equal to double thickness of the side wall 4 plus thickness of the roof member 3 (X as shown in figures 4 and 5) so that the base 12 of the end wall 5 is being able to be put on the upper
horizontal surface of the floor member 2 when the end walls 5 are being put into unfolded (upright) position (as shown of figure 6).
The portable collapsible building structure 1 further comprise a means 13 for raising the roof member 3 to enable the side wall sections 6 and 7 to pivot into an upright position (figures 9-12). The means 13 comprise:
- threaded bars 14 rotatably mounted in the end walls 5 (i.e. between front 15, rear 16, base 12, top 17, right 18 and left 19 surfaces of the end walls 5) perpendicularly to the end walls' 5 frame horizontal members (the portable collapsible building structure 1 is preferably provided with four threaded bars 14 - two of them being rotatably mounted in each side of the first end wall 5 [i.e. one threaded bar 14 closer to the left surface 19 of the first end wall 5, but another - to the right surface 18 of the first end wall 5] and the other two - on each side of the second end wall 5, each threaded bar 14 is provided with lifting nut 20 having inner thread being able to move along threaded bar 14,
- roof member 3 lifting fork 21 having first and second end, the first end of the lifting fork 21 being mounted to the roof member 3 and the second end of the lifting fork 21 being mounted to the lifting nut 20 (either fixedly or detachably) so that rotation of the threaded bar 14 around its vertical axle causes moving lifting nut 20 along threaded bar 14 (up or down) and thus, moving the lifting fork 21 and the roof member 3 up or down, depending on the side of rotation of the threaded bar 14. Thus the rotational movement of the threaded bar 14 is transformed into a linear transfer movement of the lifting fork 21 and the roof member 3. The means 13 preferably further comprise lifting nut guiding means 22 to guide lifting nut 20 during its movement and reduce flexure of the threaded bar 14.
According to the preferred embodiment the lifting nut 20 is in the form of parallelepiped having reach-through hole with thread and two slits in the opposite sides of the lifting nut 20, which are parallel to said reach-through hole (figure 12). The lifting nut guiding means 22 may be in the form of two angle bars, which are fixed from the opposite sides of the threaded bar 14 in parallel to the threaded bar 14 so that one flange of each angle bars is partially accommodated into lifting nut's 20 slit (figure 11).
To make assembling the portable collapsible building structure 1 more convenient and quick, as well as to make lifting of the roof member 3 uniform, each threaded bar 14 is being provided with a gear 23 wherein gears 23, which are fixedly mounted on the threaded bars 14 being located in the same end wall 5, are connected by drive 24, for example, chain drive allowing synchronous rotation of the threaded bars 14 being mounted
in one and the same end wall 5. Each end wall 5 or floor member 2 may be provided with access point 25 (figure 10), such as closable aperture, for accessing gear 23 or threaded bar 14 to enable rotation of the threaded bar 14 by means of electrical or pneumatic devices or by manual rotation.
The end walls 5 and floor member 2 are being provided with locking or fixing means 26, such as catch, fastener, holder or similar means adapted to releasably holding the end walls 5 in the vertical (upright) position.
The building structures 1 can be put one onto another to provide a multi-storey building. In this case the building structures 1 can be provided with supporting means in the centre of the inner side of the side walls 4 adapted to be put into a vertical position, block collapsing inwardly of the side walls 4 and/or provide the additional support to the floor member 2 and the roof member 3 during exploitation of the building structure 1.
The portable collapsible building structure 1 may also comprise a shipping bracket 27 for holding the building structure 1 in a collapsed position during its transportation or storage. The shipping bracket 27 may be adapted to releasably connect the floor member 2 and end walls 5 being in folded position.
For enabling joining several building structures 1 together to provide one big room, the building structures 1 can be provided with one or more foldable segments 28 in place of one or both the side walls 4. Like side walls 4, the segments 28 comprise at least and preferably two pivotally connected sections 6 and 7, the sections 6 being pivotally coupled to the roof member 3 and the other of the sections - 7 being pivotally coupled to the floor member 2 such that the segments 28 can collapse inwardly so that the sections 6 and 7 are substantially parallel with the floor member 2 and the roof member 3.
The portable collapsible building structure 1 is prefabricated and can be delivered on-site in a collapsed condition as shown on figure 1. Then the building structure 1 may be taken off the truck by a crane or forklift truck and located in a place, where intended to be erected. Further, after removing shipping brackets 27 the end walls 5 should be pulled out to the distance, which is equal to double thickness of the side wall 4 plus thickness of the roof member 3 (figure X). The distance of end walls' 5 sliding out and sliding in is controlled by means of stoppers 10 and is guided by the guide bar 9. On the next step the end walls 5 are being lifted up one after another into the vertical position and automatically releaseably fixed using locking or fixing means 26 (figures 3 and 4). Pulling out and lifting up the end walls 5 can be carried out using physical strength of two adult persons. On the
next step the lifting up of the roof member 3 and the side walls 4 is being performed by simultaneous rotation of one threaded bar 14 in each end wall 5 either manually through the access point 25, or by means of electrical or pneumatic devices (e.g. electric drill or pre-installed motor). Due to connection of the gears 23 by the drive 24, rotation of one threaded bar 14 in each end wall 5 causes rotation of another threaded bar 14 in the same end wall 5. At the same time rotation of the threaded bars 14 causes moving up lifting nuts 20 along the threaded bars 14 and thus, moving up the lifting fork 21 together with the roof member 3 and pivoting the side wall sections 6 and 7 into an upright position (figures 7 and 9). Being erected the portable collapsible building structure 1 is a stable shockproof construction, transportable in a horizontal or vertical position. If one of the threaded bars 14 fails to work, the building structure 1 remains stable even with three working threaded bars 14 mounted in the corners of the building structure 1.
Supporting structures of the collapsible building structure 1 can comprise profiles made of wood, metal, or other load bearing materials. Side walls 4 and roof member 3 can be produced using industrially manufactured stone wool panels, and/or solid wood cellular material panels. All types of mountable and fixable finishing materials and panels can be used for finishing of the collapsible building structure 1. Doors and windows can be built in the end walls 5. Besides that windows can be built in the side wall sections 6 and 7. The roof member 3 may have single-pitch or double-pitch roof and may have bitumen, tinplate, polycarbonate or other equivalent roofing. The building structure 1 can be provided with wiring within the side walls 4, end walls 5, floor member 2, and/or roof member 3 to enable electric power to be supplied to the building structure 1.
Due to offered kind of connection and order of opening and closing of the walls and the roof member, as well as construction of the means for raising the roof member, the portable collapsible building structure can be quickly assembled, is safe, stable and steady during the whole process of assemblage, also when it is windy and at moderate seismic activity conditions.
