Definitions

  • the invention pertains to the technical field of profiles, and in particular tent profiles, to which one or more reinforcements can be attached.
  • the present invention may therefore pertain to structural elongated elements designed for load-supporting (IPC E04C3/00), typically of metal (IPC E04C3/04).
  • DE 2 547 897 describes an extruded hollow girder, in which regions of high tensile stress are reinforced with high tensile strength strips inserted in a hollow slot of the girder and secured to the ends of the girder.
  • US 3 972 529 describes a tubular profile with recesses along the outer surface in which unidirectional graphite fiber reinforcement strips are applied.
  • US 6 647 692 discloses a support and connecting metal profile for large tent constructions, whereby the profile body is provided with fiber composite reinforcements and circular grooves opened towards the outside.
  • Profiles can be subject to substantial bending stress. Thereby one part of the profile can be subject to longitudinal compression, i.e. compression along the length of the profile, while another part can be subject to longitudinal stretch, i.e. stretch along the length of the profile.
  • the reinforcements described above may help for stretch forces or tensile stress, but are not configured for compression.
  • not all of the above profile reinforcements are configured uniformly to absorb forces from any direction perpendicular to the profile.
  • the reinforcements described above are permanently incorporated in the profiles.
  • the profiles above are not adapted for easy attachment/detachment of the reinforcements. It may be desirable to adapt a profile on a case-by-case basis, whereby the reinforcement does not have to be shipped/sold for each use, but only when required. This would allow for material, transport weight, fuel and economic savings.
  • the above profiles are not adapted for attachment/detachment of a reinforcement to the profile when part of a build-up tent framework.
  • the present invention aims to resolve at least some of the problems mentioned above.
  • the present invention provides a modular construction system for a tent, according to claim 1.
  • the present invention provides a reinforcement profile for tent construction, according to claim 12.
  • the present invention provides a method for tent construction, according to claim 14.
  • the present invention is advantageous as the reinforcement profiles can be longitudinally, externally and removably attached to the basis profile, thereby yielding a reinforcement wall external to and spaced from the basis profile.
  • the reinforcement wall thereby provides for reinforcement against both longitudinal compression as well as longitudinal stretch, and hence also against bending stress.
  • the present invention concerns a modular construction system for a tent, a reinforcement profile for tent construction, and a method for tent construction.
  • the invention has been summarized above. In what follows, the invention is described in detail, preferred embodiments are discussed, and the invention is illustrated by means of examples.
  • Tent refers to a structure which comprises a framework comprising a profile.
  • the structure is preferably temporary, but may alternatively be permanent.
  • the tent may further comprise elements for closing off the roof or walls of the tent for protection against wind and rain, such as, for example, a sheet of fabric, a canvas, a rigid panel, and the like.
  • Profile refers to a structural elongated element for load-supporting.
  • a profile can be used as, for example, beam or column in, for example, a tent framework.
  • Longitudinal in conjunction with a profile or profile component refers to the length direction of the profile, i.e. the elongation direction, which in case of an extruded profile is also typically the extrusion direction.
  • longitudinal profile component and profile component “extending in the length direction of the profile” are synonymous.
  • two “longitudinally” attached profiles comprise mutually in essence parallel length directions.
  • the invention provides a modular construction system for a tent.
  • the system comprises a basis profile and one or more reinforcement profiles.
  • the system is adapted to longitudinally, externally and removably attach the reinforcement profiles to the basis profile.
  • a reinforcement profile and the basis profile comprise an attached configuration in which the reinforcement profile comprises a reinforcement wall spaced from the basis profile.
  • the invention provides a reinforcement profile for tent construction.
  • the reinforcement profile comprises a length direction.
  • the reinforcement profile further comprises a tangent wall, support walls and a reinforcement wall.
  • the tangent, support and reinforcement walls are in essence parallel to the length direction.
  • the reinforcement wall is spaced from the tangent wall by an air gap and said support walls.
  • the invention provides a method for tent construction.
  • a basis profile is provided.
  • a reinforcement profile comprising a length direction, a tangent wall, support walls and a reinforcement wall is provided.
  • the tangent, support and reinforcement walls are in essence parallel to the length direction.
  • the reinforcement wall is spaced from the tangent wall by an air gap and said support walls.
  • the method comprises the step of longitudinally, externally and removably attaching the reinforcement profile to the basis profile, thereby obtaining an attached configuration in which the reinforcement wall is spaced from the basis profile.
  • the present invention is advantageous as the reinforcement profiles can be longitudinally, externally and removably attached to the basis profile, thereby yielding a reinforcement wall external to and spaced from the basis profile.
  • the reinforcement wall thereby provides for reinforcement against bending stress, i.e. reinforcement against both longitudinal compression as well as longitudinal stretch.
  • external attachment is also less limited in space. More reinforcement profiles can be attached. The reinforcement profiles are not limited to the available internal space of the basis profile. External reinforcement profiles may furthermore be configured for layer-wise attachment, i.e. a first reinforcement profile may be externally attached to the basis profile, and a second reinforcement profile may be attached to the first reinforcement profile. To obtain sufficient strength with internal reinforcement profiles as opposed to external reinforcement profiles, more complicated designs, thicker walls and/or stronger materials are needed.
  • the modular construction system according to the first aspect may comprise a reinforcement profile according to the second aspect.
  • the method according to the third aspect may pertain to a basis profile and a reinforcement profile of a modular construction system according to the first aspect.
  • the three aspects of the present invention are therefore interrelated. In what follows, distinction between the different aspects may therefore be left out.
  • the disclosure, embodiments and examples may relate to each of the three aspects of the present invention.
  • a reinforcement profile comprises a tangent wall, support walls, and a reinforcement wall.
  • the reinforcement wall is spaced from the tangent wall by an air gap and said support walls. Thereby, the air gap lies in between said reinforcement, tangent and support walls.
  • a reinforcement profile externally attached to the basis profile comprises a tangent wall in contact with the basis profile, i.e. in said attached configuration the tangent wall of the reinforcement profile is in contact with the basis profile. In that case, the support walls space the reinforcement wall from the basis profile.
  • a hollow reinforcement profile comprising an air gap in between the reinforcement wall and the tangent wall is advantageous over a massive reinforcement profile, as it requires less material than a massive reinforcement profile, while still providing sufficient reinforcement against bending stress. Less material has the further advantages of less weight and less economic cost, the latter both for manufacturing and for transport.
  • the reinforcement wall of the reinforcement profile is spaced from the basis profile by a distance of at least 4 mm, preferably at least 6 mm, more preferably at least 8 mm, even more preferably at least 10 mm, yet even more preferably at least 12 mm, most preferably at least 14 mm, such as 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, or any value above or in between.
  • the basis and reinforcement profiles comprise a mutually in essence equal length along the length direction.
  • the basis profile comprises a plastic, a composite, a metal or an alloy, preferably a metal or an alloy, more preferably steel or aluminum, even more preferably aluminum.
  • the basis profile is an aluminum profile. Aluminum is advantageous as it combines low weight with good strength characteristics.
  • the basis profile is manufactured by extrusion.
  • the basis profile is an extruded profile.
  • the basis profile is an extruded metal profile, more preferably an extruded aluminum profile.
  • a reinforcement profile comprises a plastic, a composite, a metal or an alloy, preferably a metal or an alloy, more preferably steel or aluminum, even more preferably aluminum.
  • the reinforcement profile is an aluminum profile. Aluminum is advantageous as it combines low weight with good strength characteristics.
  • a reinforcement profile is manufactured by extrusion.
  • the reinforcement profile is an extruded profile.
  • the reinforcement profile is an extruded metal profile, more preferably an extruded aluminum profile.
  • the basis profile comprises one or more, preferably multiple, longitudinal connection recesses and each reinforcement profile comprises one or more, preferably at least two, longitudinal connection protrusions, whereby each connection protrusion is adapted to hook and slide in a connection recess of the basis profile.
  • the reinforcement wall of a reinforcement profile also comprises a connection recess, more preferably a longitudinal connection recess, even more preferably at least two longitudinal connection recesses.
  • connection protrusions comprises a T-shaped connection protrusion, an L-shaped connection protrusion, a question-mark- or hook-shaped connection protrusion, an in essence cuboid head supported by a neck, and an in essence cylindrical head supported by a neck.
  • a connection protrusion comprises an in essence cylindrical head supported by a neck.
  • a connection recess is an in essence cylindrical cavity provided with a mouth. The cylindrical cavity is thereby open towards the outside of the profile via the mouth.
  • An example of a connection recess which is an in essence cylindrical cavity provided with a mouth is a Keder rail.
  • An example of a connection protrusion comprising an in essence cylindrical head supported by a neck is a Keder protrusion.
  • a reinforcement profile comprising a reinforcement wall comprising connection recesses is advantageous as these connection recesses allow for attachment of other reinforcement profiles and/or attachment of a tent fabric.
  • an attachment system can be provided without said connection recesses and said connection protrusions, i.e. an attachment system which does not involve hooking and sliding of connection protrusions in connection recesses.
  • the attachment system may involve the approach of a reinforcement profile towards the basis profile along a direction in essence perpendicular to the length direction, and the subsequent attachment of the reinforcement profile to the basis profile, for example via transversal fixation holes and elongated connection members, as described below.
  • the system comprises at least two, preferably at least three, and most preferably at least four reinforcement profiles.
  • the basis profile is adapted for attachment of the at least two, preferably at least three, and most preferably at least four reinforcement profiles to the basis profile. This is advantageous as it allows to reinforce the basis profile as needed, i.e. on the needed locations and/or against a particular magnitude of bending stress.
  • the basis profile comprises an in essence rectangular cross section.
  • said "in essence" rectangular cross section may allow for deviations from a perfect rectangular cross section, in particular for attachment recesses, such as said connection recesses for reinforcement profiles and/or other attachment recesses.
  • An in essence rectangular cross section may also comprise rounded corners.
  • the tangent wall of a reinforcement profile comprises two in essence perpendicular wall segments. Both wall segments of the tangent wall of a reinforcement profile externally attached to the basis profile are thereby in contact with the basis profile, i.e. in said attached configuration both wall segments of the tangent wall are in contact with the basis profile.
  • the tangent wall comprises at least two connection protrusions. More preferably, the at least two connection protrusions are two longitudinal in essence cylindrical heads, i.e. in essence cylindrical heads extending in the length direction, each supported by a longitudinal neck, i.e. a neck extending in the length direction. Most preferably, each of said wall segments of said tangent wall comprises at least one of said connection protrusions.
  • the reinforcement wall comprises one or more longitudinal in essence cylindrical cavities each comprising a longitudinal mouth.
  • a single reinforcement profile thereby provides for reinforcement against bending stress in two mutually perpendicular transversal directions, both transversal directions perpendicular to the length direction.
  • a reinforcement profile thereby further protects a corner as well as (part of) several sidewalls of the basis profile against accidental collision.
  • each of the basis and reinforcement profiles comprises a multitude of transversal fixation holes for relative fixation of the basis profile and a reinforcement profile by means of an elongated connection member.
  • the transversal fixation holes are configured for insertion of the elongated connection member in a transversal direction in essence perpendicular to the length direction of the reinforcement profile. This is advantageous as it prevents a reinforcement profile attached to the basis profile to slide in the length direction.
  • both end portions of basis and reinforcement profiles comprise a multitude of transversal fixation holes.
  • transversal fixation holes may be provided over the whole length of basis and reinforcement profiles.
  • the basis profile and the reinforcement profiles are adapted for attaching a reinforcement profile to the basis profile when part of a build-up tent framework, without detachment of the basis profile from the build-up tent framework.
  • a build-up tent framework comprising said basis profile is provided, and the reinforcement profile is attached longitudinally, externally and removably to said basis profile of the build-up tent framework, thereby obtaining an attached configuration in which the reinforcement wall is spaced from the basis profile.
