Definitions

• the present invention relates to a cover construction, such as e.g. a weather protection device for building sites or the like, comprising a number of beam members arranged to be assembled into a frame con- struction by means of lockable, rigid or hinged connecting pieces, said frame construction consisting of a number of frame bows formed by upright lateral beam members, the lower ends of which are supported on a supporting surface and the upper ends of which support roof beam members extending across said building site or the like, the frame bows being retained in spaced-apart relationship by means of spacer poles extending between the frame bows and being arranged to support covering means, such as e.g. flexible cloth, extending between and along said spacer poles.
• the cover construction may be used for a wide variety of other uses or applications, such as for storage buildings, industrial buildings, aeroplane sheds, vehicle garages, or in other connections where people congregate and weather protection is required.
• the main object of the invention is to provide an easily manageable cover structure of the above kind which despite its simple construction is comparatively flexible to allow adaptation thereof to the spatial requirements at the place of erection of the cover construction.
• a cover construction of the kind referred to according to which the lateral beam members and the roof beam members consist of hollow profile sections, wherein the transition between these two types of beam members is formed by a joint having mutually hingedly interconnected legs arranged to be coupled to the lateral beam member and to the roof beam member, respectively, and wherein a locking strut extends between attachment fittings located at points on either side of and spaced from said joint on beam members coupled together by said joint, said strut maintaining the desired angle of articulation.
• the legs of the joint have an external configuration matching the inner cavities of the lateral beam members and the roof beam members, respectively, in order to telescopically engage with said cavities. This arrangement allows the beam members to be easily assembl- ed via said joint.
• strut attachment fittings join together beam members and locking struts, said strut attachment fittings and beam members being formed with engagement means arranged for mutual hook-like co-operating engage- ment, in addition to which locking means are provided to lock the respective strut attachment fittings in their positions of engagement.
• engagement means arranged for mutual hook-like co-operating engage- ment, in addition to which locking means are provided to lock the respective strut attachment fittings in their positions of engagement.
• the beam members are formed with longitudinally extending ledges having undercut lateral edges of a hook-like cross-section shape for the purpose of co-operation with the associated strut attachment fitting.
• This arrangement provides excellent possibilities of adjustment of the positions of the strut attachment fitting along the associated beam members.
• the strut attachment fitting is in the form of a profile rail having a U-shaped cross-sectional configuration, the external face of the web of the U- shape rail being formed with said engagement means. Despite the large number of choices of possible set positions of said fitting along the associate beam member the engagement between the respective strut attachment fitting and the beam member becomes extremely safe and efficient .
• the locking means preferably is formed by at least one locking pin, which extends through a first aperture formed in the U-shaped profile rail and which is removably insertable into a second aperture formed in the beam member, the length and the location of said locking pin in the U-shaped profile rail, which forms said strut attachment fitting, being so adjusted that said means is blocked in its position of engagement by the end portion of the strut as said end portion is secured in the strut attachment fitting. Owing to this construction, efficient anchoring of the strut attachment fitting is achieved in the desired position of displacement as seen along the beam member.
• the U-shaped rail which constitutes the strut attachment fitting, is formed with abutment shoulders, said shoulders arranged to co-operate with parts associated with the locking pin and so located that said parts associated with the locking pin abut against said shoulder, when said pin is completely retracted from the aperture in the lateral beam member but still is received in the aperture in the strut attachment fitting, whereby said pin is held connected to the strut attachment fitting such that it cannot be lost, even when the associated strut is detached therefrom.
• This arrangement ensures that components that are essential to the strut attachment fitting are associated with onfe another, also when the fitting is not mounted.
• the arrangement provides and ensures automatic anchoring of the strut attachment fitting to the beam member in the mounted position of the locking strut.
• the abutment part on the locking pin is in the form of an abutment plate, which extends along the bottom of the U- shaped rail.
• the abutment means thus created has a considerable extension, whereby it may efficiently guide the locking pin associated with it, preventing the latter from tipping over while at the same time it offers wide- area and consequently safe abutment contact.
• the locking pin is formed by a bolt, which is screwed into the aperture formed in the web of the U-shaped profile rail, said bolt having a circular head and its principal diameter corresponding to or being somewhat smaller than the diameters of the apertures in the web of the U-shaped profile rail and in the roof/lateral beam members, respectively.
• the resulting locking element is simple and in a convenient manner it may be replaced and be adjusted, for instance as to its depth of penetration.
• the abutment plate is formed with at least two locking pins spaced along its surface. This arrangement increases the safety of the engagement.
• the beam members and connecting pieces that form part of the cover construction are formed with longitudinally extending edge fastening grooves for reception therein of leach edges on the associated covering means.
• these edge fastening grooves are configured as profiled channels formed in the beam members.
• These grooves for reception therein of the leach edges of the covering means preferably are located adjacent oppositely positioned side edges on the beam members and connecting pieces, respectively, in order to accommodate therein engageable grip fastening ledges positioned therebetween for attachment of other equip- ment. In this manner a construction is obtained, which in a very convenient manner may be equipped with the covering means in question, such as a cloth or the like, while at the same time temporary and permanent equipment may be easily anchored to the beam members.
• the beam members are extruded with the fastening grooves as well as the fastening ledges being formed integrally with the members during the very extruding process, the beam members are easily adapted as to their length dimensions, to the location where the cover construction is to be used.

• the joint is formed by two hinge lugs 24 projecting outwards from leg portion 7a and a hinge lug 25 projecting from leg portion 7b so as to nest between hinge lugs 24.
• the external profile configuration of the legs or insert portions 7a and 7b, respectively is designed to match that of the interior cavity 17 of the beam members, whereby these portions may simply be slid into said members in a shape-matching, nesting relationship therein and preferably be secured to the beam members by means of cotter pins, screws, bolts or similar fastening means.
• the joint 7 is formed on one of its sides with a guide portion 26 with guide grooves 18''' which like guide grooves 18' and 18" are intended to form a continuation of the corresponding guide grooves of the beam members beyond the connecting pieces or joint.

• hook-shaped engagement means 33 protrude from the lower face of the web 31 for hook-like engagement with the border edges of the fastening ledges 19 of the undercut grooves of the associated beam member.
• Numeral reference 34 designates an abutment plate, which is supported on the bottom of the U-shaped profile rail and into which is screwed, in accordance with the shown embodiment, two screws formed with a rounded head and with an internal key-engagement socket.
• the screws extend through apertures formed in the beam member 5, 6 and the web 31, respectively, and the portion of the screws that projects beyond the abutment plate 34 is adjustable by screw-adjustment of the screws, owing to associated threads formed in the abutment plate 34.
• the U-shaped rail of the strut attachment fitting 13 is wider in the area closest to the rail bottom, i.e. the web 31, and the transition between said wider section and the rest of the rail legs forms an abutment shoulder which forms a stop means restricting the movement of the abutment plate 34 in the direction indicated by arrow A.
• the locking strut 12 is omitted from Fig 7.
• the beam member wall is adapted to ensure that the locking pin 35 assumes a position wherein it is extracted from the beam member but still projects into the wider recessed portion of the web 31, when the abutment plate 34 abuts against the abutment shoulder 36 in the removed position of the locking strut 12.
• the beam member preferably is provided with a number of suitably located apertures for reception therein of the locking pin 35.
• the locking strut When the locking strut is removed from the attachment fitting, the latter may be displaced along the beam member, with the abutment plate 34 assuming an upper position in abutment against the shoulder 36, and be removed from the beam member.
• the locking pins 35 do, however, retain the abutment plate 34 inside the strut attachment fitting in a permanent way, which means that these parts cannot be lost but are always in position when a beam assembly operation is again to take place.
• the abutment plate In the mounted position of the locking strut 12, the abutment plate is maintained depressed against the web 31 owing to its abutment against the bearing/mounting sleeve 29,, i.e. in a position wherein the locking pins 35 are inserted into the wall of the beam member and consequently the strut attachment fitting safely secured in its intended posi- tion on the beam member, also when under heavy load.
• the angular position of the lateral beam member relative to the roof beam member 6, i.e. angle ⁇ may be varied in accordance with the shown embodiment by altering the length of the locking strut as well as by changing the position of the strut attachment fitting 13 on the respective beam member.
• the strut attachment fitting is in the form of a continuous profile section but it is within the scope of the invention to configure the engagement means 33 thereof differently than in the form of longitudinally extending ledges.
• these grip means are short hook members spaced suitable intervals apart along the strut attachment fitting.
• the base member and the runner wheel, designated in Fig 1 by numeral references 16 and 15, respectively, are shown in more detail in Figs 8-10.
• the base member 16 is formed with an insert portion 16a the external configuration of which matches the shape of the recess 17 in the lateral beam member 5 so that it may be slid into the latter in nesting relationship therewith.
• Numeral reference 37 designates a jacket part, the external shape of which conforms with that of the beam member in the same manner as the jacket parts 20 and 21 described above with respect to the two connecting pieces 8 and 9, respectively.
• Numeral reference 38 designates two depending mounting lugs formed with mutually coaxial shaft-receiving borings 39.

• the runner wheel is formed with a peripheral track having a rounded cross-sectional configuration.
• the rail 14, on which the wheel travels and which is deposited on the supporting face U, is formed with a track head 41 of similarly rounded configuration. In consequence of this rounded shape of the peripheral track of the runner wheel
• the base member 16 may be placed on and displaced along the rail 14 while assuming various positions of inclination. Because the runner wheel is configured to abut against the rail with different axis inclination, one and the same cover construction may be adapted to a comparatively large extent to the area one wishes to be at disposal underneath the cover construction, which area is determined by the spacing between the rails 14. Adaptation thus may be effected by changing the position of inclination of the lateral beam members 5.
• the base member 16 is formed with a centrally located cavity 42 intermediate the lugs 38.
• an insert portion 43 of matching configuration may be pushed into said cavity in nesting relationship therewith, said insert portion 43 preferably having a non-round configuration, like also preferably cavity 42.
• a foot plate 45 is journalled to the insert portion 43 via a pivot 44.
• the insert portion is formed with a number of transverse attachment holes 46 to allow variation of the depth of penetration of the insert portion 43 into the base member 16. Setting of the height position may be effected by introduction of a pin 40 through the holes 39 formed in the lugs 38 and a suitable one of holes 46 in the insert portion.
• the insert portion of the base member 16 that projects into the beam member is adapted to allow it to be turned over 90° relative to the direction illustrated in Fig 8, viz the runner wheel will in this case be directed at an angle of 90° relative to that illustrated in the drawing.
• the runner wheel may be supported on the ground or other supporting surface during the erection of the frame construction, and instead of the supporting plate 45 sliding along the supporting surface in the direction indicated in Fig 8 by arrow B, the runner wheel 15 may roll on the supporting surface.
• the runner wheel 15 may be replaced by a runner wheel that is well suited to the supporting surface, for instance one having a soft periphery.
• a further rail 14 may be deposited on the supporting surface so as to extend in the direction of the movement, i.e. at right angles to the rail 14, to be used during the very erection of the construction.
• the foot plate 45 may be secured directly to the supporting surface by means of cotter pins or similar fasteners inserted through the apertures 47 formed in the plate.
• a safety device 53 may be attached to the base member, for instance as indicated by broken lines in Fig 8 and preferably in the manner of a hook devised to grip a flange on the rail 14, or in any other manner holding the base member and the rail in a coupled-together relationship.
• the safety device and/or the base member preferably are provided with a number of apertures for passage therethrough of bolts for the purpose of adaptation of the position of assembly of the safety device on the base member relative to the rail, independently of the inclination and any height position of the lateral beam and thus of the base member.
• Fig 11 illustrates the manner of attaching the spacer poles 3, 4 between the lateral beam and roof beam members 5 and 6, respectively.
• Numeral reference 48 designates fastener pieces which by means of bolts 49 or the like are attached to the beam member sides or to connecting pieces located therebetween. The fastener pieces are formed with a centrally located undercut groove 50 and with laterally projecting fastening lugs 48a in which hooks 51 or the like may engage to secure the tightening wires 10.
• Numeral reference 52 indicates the end wall at either end of the spacer poles 3, 4, said end walls formed centrally with a flange 53 the extreme end of which presents an enlarged rim 54 which may be inserted into the undercut groove 50. It goes without saying that the fastener pieces 48 may be secured in any desired location on the frame bows, i.e. also on the strut attachment fittings 13 as shown in Fig 1.
• Figs 12-16 a suitable mode of operation for erection of the frame construction in accordance with the invention will be described.
• the various beam members forming part of the frame construction are shown coupled together by means of the corresponding connecting pieces, joints, spacer poles, tightening wires, and so on.
• the locking struts 12 are not yet fastened.
• the mounting and assembly work is easy, since the height of the con- struction is low at this stage and the assembly and mounting operation may be effected with the aid of comparatively simple equipment without requiring high- reaching cranes or similar lifting equipment.
• It is likewise possible to position the cover by sliding the leach edges thereof into the fastening grooves 18 extending along the various members.
• lifting tools 55 preferably one at each frame bow, have been arranged in the vicinity of one of the joints between the roof beam members and the lateral beam members, viz. at the left-hand joint as seen in Figs 12-16. From the position in Fig 12, wherein the beam members are angled downwards, the beam members have been lifted so as to be angled upwards. When a tightening force is applied intermediate the opposite joint 7 and the base member 16 it becomes possible, while the base member 16 is sliding on the supporting surface, to continue the lifting movement until the base member has reached a position adjacent the corresponding rail 14.
• the locking strut 12 may be applied in order to lock the roof beam members and the lateral beam members in their relative angular position. Thereafter, the same procedure may be repeated with respect to the opposite side, as appears from Fig 16, it thereafter becoming possible to apply the locking strut also at this side.
• the length of the locking struts preferably is adjusted by rotation of the stretching screws. Should a building crane or similar equipment be available on the site, it may of course be used for the erection.
• suitable lifting fittings may be applied on the central grip ledges of the roof beams by means of grip edges engaging the ledge edges and projecting into the undercut grooves formed there.
• frame bows need not either have a symmetrical configuration but their shape could be adapted to suit the needs expressed by the user, without departing from the basic concept of the invention. Additional modifications are possible within the scope of the appended claims.
• the joint 7 may be used in other positions than to interconnect a lateral beam member and a roof beam member, for instance to couple together two adjoining roof beam members to form an adjustable roof-ridge or other roof angle. It is likewise possible to place it between two mutually inter- connected lateral beam members.
• the rigid connecting pieces could be used within wide limits in other positions than the one shown in the drawing figures.
• the covering means could be rigid, such as in the form of roofing sheets or the like.
• the screws 35 may be replaced by pins welded to or in any other way attached to the abutment plate 34.
• the beam members need not have a hollow profile configuration that is completely closed circumferentially . One side thereof could for instance be wholly or partly open.
