    CONVEYOR TRACK CLAMP Field of the Invention This invention pertains in general to a connecting means for connectingconveyor systems to scaffolding at a building site. ln particular the invention relates to a clamp for connecting a conveyor track to a supporting scaffold.
    Background of the Invention Conveyor systems are commonly used in the movement of objects along a pathsuch that the elements do not contact the ground or floor. Conveyor systems areespecially useful in applications involving the transportation of heavy objects.
    One type of conveyor system is an overhead conveyor system in Which a fixedtrack is assembled and in Which a trolley is positioned. Objects to be moved can beconnected to the trolley Which can move Within the track.
    Such overhead conveyor systems can typically be found in factories Whereparts to be for example painted are moved from a painting location to a drying location.ln such a system the track is constructed as a relatively permanent feature of the factoryand remains constructed for long durations. Furthermore, as conveyor systems can beused to move objects of substantial Weight the systems require robust and reliableassembly. Such systems are therefore costly and time consuming to assemble.
    There is therefore a need for a conveyor system Which is less time consumingand costly to assemble.
    Scaffolding or staging is traditionally erected in most construction projects.Scaffolding is a temporary structure generally used to support a Work crew andmaterials to aid in the construction, maintenance and repair of buildings. As scaffoldingis temporary it is generally easy to assemble and disassemble. Scaffolding systems canfor example be reused in multiple building projects.
    Multi-storey buildings often comprise a facade acting as either a load-bearingstructure or as a Weather protective structure. The facade is generally constructed from individual facade elements Which are installed in one of a variety of Ways to the building. Facade elements are often transported to the building site on trucks. Theelements are off-loaded, stored, and subsequently installed to the building.
    As the building site undergoes numerous re-developments depending on whichaspect of the building is being installed a conventional conveyor system is notappropriate for the transportation of facade elements. A conveyor system being easy to assemble and disassemble on a building site is thus required.
    Summary of Invention Accordingly, the present invention preferably seeks to mitigate, alleviate orelin1inate one or more of the above-identified deficiencies in the art and disadvantagessingly or in any combination and solves at least the above mentioned problems byproviding a clamp for connecting a conveyor track to a supporting scaffold comprising:two clamping elements, the clamping elements being provided with a first region forengaging the supporting scaffold and a second region eXtending from the first region forattachment to a conveyor track; wherein the clamping elements are provided with adovetail shaped edge at the first region, such that the two clamping elements caninterlock into a dovetail joint for engagement with the supporting scaffold.
    A clamping element for such a clamp is also provided.
    Advantageous embodiments of the inhaler are described below and in the appended dependent claims.
    Brief Description of the Drawings These and other aspects, features and advantages of which the invention iscapable of will be apparent and elucidated from the following description ofembodiments of the present invention, reference being made to the accompanyingdrawings, in which Fig. l is a perspective view of a clamp comprising two clamp elementsshowing a conveyor track and a supporting scaffold, according to one embodiment ofthe present invention; Fig. 2 is a top down partial view of a clamp element focusing on the dovetail shaped edge, according to one embodiment of the present invention; Fig. 3 is top down perspective view of a clamp comprising two clamp elementsand being connected to a supporting scaffold member, according to one embodiment ofthe present invention; and Fig. 4 is a perspective view of a clamp connecting a supporting scaffold member and a conveyor track, according to one embodiment of the present invention.
    Description of Embodiments The following description of the present invention describes a clamp forconnecting a conveyor track to a supporting scaffold comprising two matchingclamping elements allowing easy assembly and disassembly. As has been describedscaffolding systems are generally easy to assemble and disassemble. A clamp being ableto connect a conveyor track to a scaffolding system being easy to assemble allows theconveyor track also to be efficiently assembled and disassembled.
    Fig. 1 illustrates a clamp 100 for connecting a conveyor track 300 to asupporting scaffold 200, comprising two matching clamping elements 101. Theclamping elements 101, for example as clamping shanks 101 or clamping legs 101, asdisclosed in Fig. 1. The clamping elements 101 are provided with a first region 102 forengaging to a supporting scaffold 200. As disclosed in Fig. 1, the first region 102 isprovided at a first end of the clamping shank/leg 101. The inner face of the first region102 is concave in shape, such as forrning a half circle, in cross section transversal to alongitudinal axis of the scaffold 200 and the conveyor track 300 onto which the clamp100 is to be arranged. In this way, two adjacent clamping shanks/legs 101 can form acircular cross-section, as disclosed in Fig. 1, to enclose/house a cylindrical scaffoldelement, such as an annular cylindrical scaffold element 200. The clamping elements101 are further provided with a second region 103 eXtending from the first region 102and being provided with a means for attaching to a member on a conveyor track. Thesecond region 103 may be located at the second end of the clamping shanks/legs 101, asdisclosed in Fig. 1. A longitudinal aXis of the clamping elements 101 is formed alongthe length of the element eXtending from the first region 102 to the second region 103.The second region 103 is preferably flat in parallel with a longitudinal aXis of thescaffold 200 and the conveyor track 300 onto which the clamp 100 is to be arranged. Inthis way, two second regions 103 of two clamping elements 101 may be closely fitted on each side of an attachment flange 301 of a conveyor track 300, such that they may be attached to each other and the conveyor track 300 through the use of a bolt or screwmember 400, eXtending from an outside of the first clamping element 101, through athrough hole 302 in the attachment flange 301, to the outside of the second clampingelement 101, and secured on that outside through the use of a nut 401. This means thatalso the second region, such as the flat second region as disclosed in Fig. 1, is providedwith through hole(s) 104, corresponding to the through hole 302 on the attachmentflange 301 of the conveyor track 300.
    The first region 102 of the clamping elements 101 is provided with a dovetailshaped edge 105. The dovetail shaped edge 105 is dimensioned such that two clampingelements 101 can interlock, by turning one clamping element 101 180 degrees aroundthe longitudinal aXis of the clamping element 101 in relation to a second clampingelement 101, and having one edge end of the dovetail shaped edge 105 open and theother edge end provided with a dovetail wedge 106. Along the edge length of thedovetail shaped edge 105 there is then provided alternating wedges 106 and openings107 shaped and sized to accommodate a wedge 106, so as to form the dovetail shapededge 105. Preferably, also the openings 107 are dovetail shaped in close resemblancewith the dovetail shaped wedge 106, so as to improve fit between two dovetail shapededges 105 into a dovetail joint.
    As disclosed the dovetail shaped wedge 106 can be part of a repeating patternof dovetail wedges forrning a dovetail shaped edge 105. As disclosed in Fig. 2 thedovetail edge 105 can comprise 3 dovetail wedges 106 projections and three dovetailopenings 107, such that one set of dovetail wedges 106/dovetail openings 107 of a firstclamping element 101 will match with the same set of dovetail wedges 106/openings107 on a second clamping element, such as disclosed in Figs. 1 to 4. In this way, there isno need for customizing each clamping element 101 after another clamping element101, i.e. manufacturing two different clamping elements 101 for forrning a dovetailjoint, but instead two identical clamping elements 101 may form a dovetail joint bysimply flipping one of them around its longitudinal aXis.
    Fig. 3 displays two clamping elements 101 coupled and interconnected at theirdovetail edges 105. The dovetail shaped edge 105 is designed such that two clampingelements can interlock. Two clamping elements 101 placed with their dovetail edges105 aligned at an offset can be interlocked. The interlocked edges 105 form anextremely strong lock when a force is applied substantially aligned with the longitudinalaXis having a direction from the first region 102 toward the second region 103 (that is, into the page in Fig. 3). The dovetail shaped edge thus allows the edges 104 of two clamping elements be connected without further means of attachment such as bolts orscrews. It is surprising that this dovetail joint is strong enough for suspending evenfacade elements for buildings, such as skyscrapers, via conveyers onto scaffolds.
    To enable reliable clamping to a tubular or pipe formed supporting scaffoldmember the first region 102 of the clamping element can be formed as a half cylindersubstantially perpendicular, such as perpendicular, to the longitudinal axis of theclamping elements 101. The half cylinder is dimensioned to surround or cup to one sideof a pipe formed member of a supporting scaffold. For example, the supporting scaffoldmember could be a member of a scaffolding system such as those provided by LayherGmbh. The Layher Gmbh scaffolding members are generally tubular or pipe formed.Whilst a half cylinder is disclosed in Figs. 1 to 4 the first region can be formed in anyshape such that it surrounds a supporting scaffold member. For instance, if thesupporting scaffold member to which the clamp is to be connected has a square cross-section then the first region would have a half-square form.
    As can be seen in Fig. 1 and Fig. 4 the second region comprises a means forattaching to a to a conveyor track 300. In Fig. 4 the second region comprises twothrough holes 104 and is secured to a member on the conveyor track 300 via bolts. Themeans for attachment to the conveyor track 300 could be any of a variety of techniquesknown in the art. For example, a single bolt could be used, pins, hooks are also possiblemeans for attachment.
    Fig. 1, Fig. 3 and Fig. 4 display how the individual clamping elements 101 arealigned to form a single clamp in form of a dovetail joint. The joint is formed by twomatching clamping elements 101 facing one another. The clamping elements 101 havefirst regions 102 for surrounding and cupping each side of a member of a supportingscaffold 200 and have interlocked dovetailed edges 105. The clamping elements 101further have a second region 103 for attachment to a conveyor track 300. The clampingelements 101 can thus be used to attach a conveyor track 300 to a scaffold 200.
    As can be seen in Fig. 4 the second region 103 of the clamping elements 101 issubstantially flat in shape, such as plate shaped. The clamping elements 101 can have asubstantially constant thickness as is shown in the cross-section of Fig. 1, to facilitatecooperation with bolts etc and attachment flanges 301 on conveyor tracks 300. Thisallows the clamping element 101 to be formed from a single piece of material, such asstainless steel of appropriate grade.
    The clamp and matching clamping elements 101 can form part of a system for the transport of facade elements at a building site. The system can comprise a conveyor track 300 and a supporting scaffold 200. The conveyor track 300 and the supportingscaffold 200 are associated via at least one set of clamping elements 101 according tothe description of the clamp 100 provided above.
    Generally multiple sets of clamping elements 101 are used for each section ofconveyor track 300. The number of sets of clamping elements 101 used between eachsupporting scaffold member 200 and conveyor track 300 is dependent on the Weight ofthe objects, for example, facade elements to be transported.
    The clamping elements 101 can be constructed of a range of materials such assteel, aluminium. It is possible to construct the clamping elements 101 from othermaterials provided they have a tensile strength capable of supporting the conveyor track300 having facade elements suspended thereon.
    Although the present invention has been described above With reference tospecific embodiments, it is not intended to be limited to the specific form set forthherein. Rather, the invention is limited only by the accompanying claims and otherembodiments than the specific above are equally possible Within the scope of theseappended claims.
    In the claims, the term “comprises/comprising” does not exclude the presence of other elements or steps. Furthermore, although individually listed, a plurality of means, elements or method steps may be implemented by e.g. a single unit or processor.
    Additionally, although individual features may be included in different claims, thesemay possibly advantageously be combined, and the inclusion in different claims doesnot imply that a combination of features is not feasible and/or advantageous. In CC 77 CC addition, singular references do not eXclude a plurality. The terms a , an”, “f1rst”,“second” etc do not preclude a plurality but include a plurality. Reference signs in theclaims are provided merely as a clarifying example and shall not be construed as lirr1iting the scope of the claims in any Way.
