Definitions
- Work site barrier systems generally comprise panels of some kind, which are supported by posts, heavy blocks of concrete or secured directly to the ground. Due to the high wind loads, it is thus critical to provide a proper securing of the panels of the system to its supporting structure. On the other hand, when used at construction sites, reconstruction of the work site barrier system should also be allowed in order to adapt to the construction site as it changes.
- the barrier 2 of the exemplifying embodiment of Fig. 1 is further a safety barrier adapted for use in vehicular traffic environments, as disclosed in EP13369863 .
- other types of barriers are also applicable within the inventive concept, provided that they comprise a groove 8 as previously described and provide a stable base for the work site barrier system.
- the barrier can be made of concrete with a top groove made directly in the concrete or by having a metal profile cast into or attached to the concrete.
- a particular advantage with providing a barrier 2 as disclosed in EP13369863 and a panel 3 of a rectangular shape, in accordance with the embodiment shown in Fig. 1 , is that it allows mounting a work site barrier system comprising several barriers and panels arranged adjacent to one another and interconnected by the barriers.

- the fastening elements 21 are arranged such that the respective bolts extend horizontally from at least one side surface of the attachment arm 25.
- each of the hook shaped protrusions of the attachment portion 17 has received a fastening element 21 of the extension panel 20. More particularly, a shaft portion of each fastening element 21, which shaft portion is smaller than the groove defined by the corresponding hook shaped protrusion, has been received in each of the hook shaped protrusions of the attachment portion 17.
- the head of the fastening element 21 is of a size that is larger than the corresponding groove defined by the hook shaped protrusion, and abuts a side surface of the attachment portion 17 facing away from the vertically arranged beam 14.
- the vertical extension of the upper hook shaped protrusion is shorter than that of the lower hook shaped protrusion.
- the second barrier engagement side portion 54 comprises a stop portion 59, see Fig. 1 .
- the stop portion 59 is arranged at an end of the second barrier engagement side portion 54 and constitutes a partial prolongation thereof.
- the stop portion 59 is arranged to extend such that the total length of the second barrier engagement side portion 54 is less than the vertical extension of the groove 8 of the barrier 2, but larger than the vertical extension at which the recesses 10 of the side walls 9 are arranged. Thereby, the stop portion 59 prevents the locking element 58 from freely rotating about the operation element 52 as the operation element 52 is rotated around its vertical axis.
- At least one of the side walls 9 comprises first and second wall portions 120, 121 being positioned adjacent to each other, and at different distances d1, d2 to a central plane A-A of the groove 8.

Description
- The present invention relates to a work site barrier system for use at, inter alia, construction sites and in vehicular traffic environments.
- Work site barrier systems are often used to enclose construction sites and alongside of roads, such to prevent people from looking into and entering the worksite, and/or reduce the spreading of noise resulting therefrom to the surroundings as well as from the surroundings, e.g. traffic noise, to the work site, etc. For the same reason, it is desirable to provide a work site barrier system of a considerable height. Providing work site barrier systems of considerable height places high requirements on the structural integrity of the barrier system, which in windy conditions is subjected to significant wind loads.
- Work site barrier systems generally comprise panels of some kind, which are supported by posts, heavy blocks of concrete or secured directly to the ground. Due to the high wind loads, it is thus critical to provide a proper securing of the panels of the system to its supporting structure. On the other hand, when used at construction sites, reconstruction of the work site barrier system should also be allowed in order to adapt to the construction site as it changes.

US2005/0104054 discloses a traffic noise barrier system including a longitudinal barrier and a traffic noise barrier wall. The traffic noise barrier wall is spaced apart from a back surface of the longitudinal barrier and attached thereto by means of transverse beams, which support the traffic noise barrier wall. The transverse beams comprise end plates at each end thereof, which end plates are secured to the longitudinal barrier on the one end, and to a post of the traffic noise barrier wall on the other end. Bolts are used for securing the end plates to the barrier and to the post of the panel, respectively. Alternatively, securing the end plates to the post of the panel can be achieved by welding. A drawback with this traffic noise barrier system is that a considerable effort is required for mounting and dismounting the system, considering that the transverse beams must be fastened to the traffic noise barrier wall at one end, and then supported by an operator or a lifting device while fastening the other end to the longitudinal barrier by means of bolts. -
AU2017276356A - There is thus a need for a work site barrier system which can be mounted and dismounted in an efficient manner.
- An object of the present invention is to overcome, or at least lessen the above mentioned problems. A particular object is to provide a work site barrier system which can be efficiently and safely mounted.
- To better address this concern, in a first aspect of the invention there is presented a work site barrier system comprising a barrier, a panel, and a connector arranged to connect said panel to said barrier. The barrier comprises a top portion having a groove, which groove comprises opposing side walls, wherein at least one side wall comprises first and second wall portions being positioned adjacent to each other and at different distances to a central plane of the groove measured in a direction normal to the plane, wherein the plane extends between an entrance opening of the groove and a bottom of the groove. The connector comprises a panel engagement portion connected with the panel, and a barrier engagement portion arranged to be received in said groove. The barrier engagement portion comprises a fixing device, arranged to engage at least one side wall at at least one of said first and second wall portions in order to fix the barrier engagement portion to the barrier.
- The connector provides a stable, preferably releasable, connection of the panel to the barrier. The barrier engagement portion of the connector provides a support for the panel when received in the groove. The fixing device then allows securing the connector, and thereby the panel, to the barrier as it is arranged to engage the at least one recess of the groove. To mount the work site barrier system, the panel, engaged with the connector by the panel engagement portion of the connector, is arranged such that the barrier engagement portion of the connector is received in the groove of the barrier. Thereafter, the fixing device is arranged to engage at least one side wall of the groove in order to fix the connector and, thus, the panel to the barrier. To dismount the work site barrier system, the fixing device is arranged to be disengaged from the recess, whereby the panel with connector can be removed from the barrier. This can ideally be done by one sole operator. There is thus provided a work site barrier system which can be easily mounted and dismounted.
- A further advantage with the work site barrier system is that the panel can be provided with the connector engaged therewith, by the panel engagement portion of the connector. This facilitates the handling of the system, i.e. the mounting and dismounting thereof, considering that the panel and connector are handled as one unit. According to an embodiment, it is, however, possible to release the connector from the panel if required, such as for example if the panel is damaged and need to be exchanged, or, if desirable, for transporting. The connector, and more particularly the panel engagement portion, is thus releasably engaged with the panel. To further optimize transport of the panel, the panel engagement portion of the connector is movably engaged with the panel, according to an embodiment of the work site barrier system. This allows adjusting the position of the connector with respect to the barrier, which can be advantageous when packaging several panels for transport.
- The barrier of the work site barrier system can be any type of barrier comprising a groove with opposing side walls as defined above. Preferably, the barrier comprises ballast providing stability to the barrier and thus to the base of the work site barrier system. Furthermore, in a preferred embodiment, the barrier is of a kind adapted for use near vehicular traffic, such as a vehicle barrier. This is advantageous when providing the work site barrier system near roads that are transited, as this type of barriers provides advantages in the case a vehicle accidently thrusts into the same.
- In accordance with an embodiment of the work site barrier system, one of said first and second wall portions is a protruding portion, which protrudes relative to the other one of said first and second wall portions, and which has a longitudinal extension along a length of the groove. According to different embodiments the protruding portion either provides a recess in the side wall or a ridge protruding towards the centre of the groove from the side wall. In case of a recess, the recess can be arranged at any height of the groove. Preferably, the recess is arranged at a lower portion of the groove. According to an embodiment of the work site barrier system, each of the vertical side walls comprises a recess. In a preferred embodiment, the recesses are arranged in the same horizontal plane. Arranging the respective recesses of the side walls in different horizontal planes is, however, also possible.
- In accordance with an embodiment of the work site barrier system, the connector comprises a support portion arranged between the panel engagement portion and the barrier engagement portion, which support portion extends across a portion of the groove and abuts against a top surface of the top portion of the barrier. This allows positioning the panel on top of the barrier, whereby the support portion of the connector provides a support for the panel thereat.
- In accordance with an embodiment of the work site barrier system, the support portion comprises an aperture and the fixing device further comprises an operation element. The operation element comprises a head and a shaft, the head at least partly abutting against a top surface of the support portion, and the shaft extending through the aperture of the support portion to a bottom portion of the barrier engagement portion. The fixing device further comprises a locking element and the shaft is engaged with the locking element. The fixing device is thus operable from the top of the barrier by the head of the operation element, abutting against the top surface of the support portion. Furthermore, the engagement of the locking element and the shaft is such that operating the operation element allows the locking element to enter in a fixed engagement with the barrier and, thus, to fix the barrier engagement portion of the connector to the barrier. This provides an easily accessible means for fixing the panel of the work site barrier system to the barrier.
- In accordance with an embodiment of the work site barrier system, the shaft comprises a threaded portion which is in threaded engagement with the locking element, whereby turning of the head in a first direction causes the locking element to enter into engagement with at least one side wall at at least one of said first and second wall portions. This allows fixing the panel to the barrier using a basic tool, such as a wrench or an impact wrench, adapted to the size and geometry of the head of the operation element. Thereby, the work site barrier system can be mounted easily and efficiently.
- In accordance with an embodiment of the work site barrier system, the barrier engagement portion further comprises a stop portion preventing the locking element from freely rotating upon turning of the head of the operation element in a second direction. Thereby, due to the threaded engagement of the operation element with the locking element, when the operation element is rotated in the second direction, in order to disengage the barrier engagement portion from the barrier, at some point the locking element is rotated along with the operation element until hitting the stop portion. The stop portion is positioned such that the locking element is aligned with the mouth of the groove, and thereby the barrier engagement portion can be removed from the groove.
- In accordance with an embodiment of the work site barrier system, the locking element comprises a base part including an elongated locking plate having a longitudinal extension exceeding a smallest width of the groove. The locking plate may be a simple flat rectangular plate having a longitudinal extension as previously described. It is also possible to provide a flanged locking plate, or a locking plate having any for the purpose suitable shape.
- In accordance with an embodiment of the work site barrier system, the locking element comprises a base part rotatably engaged with the operating element, and at least one locking part engaged with the base part, wherein turning of the head in the first direction generates at least one of a rotating movement, a pivoting movement, and a sliding movement of the at least one locking part to move the at least one locking part into engagement with at least one of the side walls at at least one of said first and second wall portions. Thereby, the barrier engagement portion is easily fixed to the barrier by turning the head of the operation element in a specific direction, for example by means of an impact wrench, providing an efficient manner of fixing of the panel to the barrier.
- In accordance with an embodiment of the work site barrier system, the panel comprises a beam structure and the panel engagement portion of the connector is in engagement with the beam structure. The beam structure typically contributes to the structural integrity of the panel and can be adapted to meet the requirements posed on the panel in terms thereof.
- In accordance with an embodiment of the work site barrier system, the panel engagement portion of the connector is in at least one of a fixed and a moveable engagement with the beam structure. Providing the panel engagement portion in a fixed engagement with the beam structure provides an advantage when mounting of the work site barrier system, as the panel and connector can be mounted onto the barrier as one unit. On the other hand, providing the panel engagement portion in a moveable engagement with the beam structure provides an advantage when it comes to packaging and transportation of the work site barrier system. It allows adjusting the position of the connector along the beam structure such to not collide with a connector of another panel, allowing a more compact packaging of several panels with connectors.
- In accordance with an embodiment of the work site barrier system, the beam structure comprises a vertically arranged beam having an overall H-shape, and the panel engagement portion of the connector comprises a C-shaped bracket arranged to receive a portion of the vertically arranged beam such to form a vertically sliding engagement there with. Thereby, the connector can be arranged at any vertical position of the vertically arranged beam. This is advantageous for packaging of the panel, as previously described. This also allows removing the connector from the panel by simply sliding the connector over the end of the beam. This allows packaging the panel and the connector separately. This is furthermore efficient when replacement of a panel or a connector is required, as it allows for an easy removal of the connector from the panel.
- In accordance with an embodiment of the work site barrier system, the panel engagement portion further comprises a fastening element arranged to fixate the panel engagement portion to the vertically arranged beam. Thus, when the connector is arranged in the desired vertical position along the vertically arranged beam, it can be fixated thereat by means of the fastening element such that the panel engagement portion of the connector is in a fixed engagement with the panel. For the purpose of transportation and replacement of a connector or a panel, it is furthermore advantageous the fastening element is releasable.
- In accordance with an embodiment of the work site barrier system, the locking element comprises two locking parts hingedly engaged with the base part at opposing sides thereof, wherein the operation element is arranged to drive the locking parts to pivot outwardly to engage the side walls of the groove upon turning the head of the operation element in the first direction. Alternatively, the locking element comprises one locking part which is driven by the operation element to pivot outwardly to engage the side wall of the groove upon turning the head of the operation element in the first direction.
- In accordance with an embodiment of the work site barrier system, the base part is plate-shaped and comprises a lateral groove at each end thereof, wherein the locking parts extend through one groove each with a play, such that upon turning the head of the operation element in the first direction, the base part causes the locking parts to pivot outwardly to engage the side walls of the groove of the barrier. Thus, as the operation element is turned in the first direction, the base part, prevented from rotating with the operation element by the stop portion, moves vertically along the extension of the operation element. Thereby, the hingedly arranged locking parts are forced to pivot outwardly such to engage each groove side wall of the barrier.
- In accordance with an embodiment of the work site barrier system, the stop portion comprises a plate arranged to extend between the opposing side walls of the groove, and comprising at least one diagonally arranged aperture. The base part is in a movable engagement with an L-shaped locking part, which is movably engaged with the diagonally arranged aperture, such that the base part and the diagonally arranged aperture causes the locking part to slide outwardly towards one of the side walls of the groove upon turning of the head of the operation element in the first direction, whereby the L-shaped locking part engages at least one side wall at at least one of said first and second wall portions. That is, when the operation element is turned in the first direction, the base part, prevented from rotating with the operation element by the stop portion, moves vertically upwards along the operation element, whereby it forces the L-shaped locking parts to move upwards. The diagonally arranged aperture is oriented diagonally upwards, such that the L-shaped locking part, upon being forced upwards, further is pushed outwards towards a side wall of the groove. This outward movement of the L-shaped locking part is further allowed by the moving engagement with the base part. Alternatively, there can be provided two diagonally arranged apertures and the base part is in a movable engagement with two L-shaped locking parts at opposing sides thereof, which in turn are movably engaged with a respective diagonally arranged aperture. Upon rotation of the operation element in the first direction, the L-shaped locking parts enter in engagement with the respective barrier groove side wall, thus providing two fixing points of the fixing device of the barrier engagement portion to the barrier.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and to fully convey the scope of the invention to the skilled addressee. Like reference characters refer to like elements throughout.
- With reference to
Fig. 1 , there is provided an embodiment of a worksite barrier system 1 comprising abarrier 2, apanel 3, and aconnector 4 arranged to connect thepanel 3 to thebarrier 2. In the particular embodiment shown, the worksite barrier system 1 comprises twoconnectors 4. The number ofconnectors 4 in the worksite barrier system 1 is, however, generally adapted to the dimensions of thepanel 3 and thebarrier 2, and to the loads to which the worksite barrier system 1 is subjected, and may thus vary. - The
barrier 2 comprises atop portion 6 having agroove 8 extending along the length of thebarrier 2, between its ends. The groove comprises a horizontal bottom surface 7, and opposingvertical side walls 9. Theside walls 9 thus extend perpendicularly to the horizontal bottom surface 7, as well as along the length of the horizontal bottom surface 7, thereby defining thegroove 8 to be generally U-shaped in cross-section. - As shown in the lower enlarged part of the
barrier 2, eachside wall 9 comprises arecess 10. Eachrecess 10 extends horizontally along theside wall 9. Therecesses 10 are here arranged close to the bottom surface 7 of thegroove 8. According to other embodiments, however, it is possible to arrange therecesses 10 at different positions along thevertical side walls 9, such as at the center thereof, or closer to a top thereof. Furthermore, although, in this embodiment of the work site barrier system, thebarrier 2 comprises arecess 10 in eachside wall 9, it is also possible to provide arecess 10 in only one of theside walls 9 of the groove, according to an alternative embodiment of the work site barrier system. - The
barrier 2 of the exemplifying embodiment ofFig. 1 is further a safety barrier adapted for use in vehicular traffic environments, as disclosed inEP13369863 groove 8 as previously described and provide a stable base for the work site barrier system. For instance, the barrier can be made of concrete with a top groove made directly in the concrete or by having a metal profile cast into or attached to the concrete. - The
panel 3 comprises a shielding plate 30 provided with aframe 13, and a beam structure with one or more beams 14. The shielding plate 30 can be made from any suitable materials, which can provide different kinds of properties, such as noise reduction, strength, etc. Some examples are a sandwich structure with a honeycomb core of plastic or aluminum, covered by surface plates of plastic, glass fiber reinforced plastic, aluminum, steel, etc., or a core of an isolation material, foamed plastic, or the like, covered by metal meshes, perforated metal or plastic sheets, or the like. Further examples are a plastic sheet, or a corrugated metal plate. Theframe 13 is, typically, a metal frame. Thepanel 3 is further generally of a rectangular shape. This allows arrangingseveral panels 3 adjacent to each other to form a work site barrier system of a desired extension. A particular advantage with providing abarrier 2 as disclosed inEP13369863 panel 3 of a rectangular shape, in accordance with the embodiment shown inFig. 1 , is that it allows mounting a work site barrier system comprising several barriers and panels arranged adjacent to one another and interconnected by the barriers. The rectangular shape of thepanel 3 allows the side edges thereof to abut side edges of an adjacent panel. When reconstruction of such a work site barrier system is needed at a non-lateral part of the system, or if damage has occurred in a single barrier, panel or connector, the affected part of the work site barrier system can be removed or rearranged by disconnecting the corresponding barrier from the adjacent barriers and removing or adjusting the same. - The beam structure is generally arranged to contribute to the structural stability of the
panel 3. In the exemplifying embodiment ofFig. 1 , the beam structure comprises two vertically arrangedbeams 14 which are spaced apart from each other in the longitudinal direction of thepanel 3. With reference toFig. 2b , showing a portion of thepanel 3 ofFig. 1 , the vertically arrangedbeam 14 is attached to opposing horizontal portions of theframe 13 of thepanel 3 by means offastening elements 15, such as bolts or other. Thevertical beams 14 of this exemplifying embodiment thereby extend across the complete vertical extension of thepanel 3, also referred to as height. Thevertical beam 14 shown inFig. 2b has an H-shaped cross-section definingelongated recesses 16 extending along the vertical extension and at both sides thereof. This shape of thebeam 14 is advantageous as it provides stability to thepanel 3. The H-shape of thebeam 14 is further advantageous for the connection of thepanel 3 to theconnector 4, as will be described in more detail further on. Providing avertical beam 14 having a different shape, such as rectangular or cylindrical, is however also conceivable within the concept of the present invention. - Further, in the exemplifying embodiment shown in
Fig. 1 , the beam structure, i.e. the vertically arrangedbeams 14, comprises anattachment portion 17 at a top end thereof, shown in more detail inFig. 2b . Theattachment portion 17 is arranged to receive or hold accessories of the worksite barrier system 1, such as signs or an extension panel. Here, theattachment portion 17 comprises two generally hook shaped protrusions arranged one above the other, which protrusions protrude in a direction perpendicular to thepanel 3. -
Fig. 3 shows a portion of another exemplifying embodiment of the work site barrier system, where anextension panel 20 is arranged at the top of thepanel 3, such to prolong the vertical extension thereof. Theextension panel 20 comprises apanel portion 22 and at least one vertically arrangedattachment arm 25. Theattachment arm 25 comprises anupper portion 26 and alower portion 27. Theupper portion 26 is attached to thepanel portion 22. Thelower portion 27 extends beyond a bottom end of thepanel portion 22 and comprisesfastening elements 21. Thefastening elements 21 are here two bolts which are fastened to theattachment arm 25 at a distance from each other in the vertical direction which corresponds to the distance between the two hook shaped protrusions of theattachment portion 17 of thebeam 14. Thefastening elements 21 are arranged such that the respective bolts extend horizontally from at least one side surface of theattachment arm 25. InFig. 3 , each of the hook shaped protrusions of theattachment portion 17 has received afastening element 21 of theextension panel 20. More particularly, a shaft portion of eachfastening element 21, which shaft portion is smaller than the groove defined by the corresponding hook shaped protrusion, has been received in each of the hook shaped protrusions of theattachment portion 17. The head of thefastening element 21 is of a size that is larger than the corresponding groove defined by the hook shaped protrusion, and abuts a side surface of theattachment portion 17 facing away from the vertically arrangedbeam 14. This allows thefastening elements 21 to rotate around their respective horizontal axis while being received in theattachment portion 17 of thebeam 14 of thepanel 3. Furthermore, in this exemplifying embodiment, the vertical extension of the upper hook shaped protrusion is shorter than that of the lower hook shaped protrusion. When the twofastening elements 21 of theattachment arm 25 are received in the corresponding hook shaped protrusions of theattachment portion 17, the extension panel is fixed in a raised position, in which it vertically protrudes from thepanel 3 such to provide an extension thereto. When arranging theextension panel 20 at thepanel 3, theextension panel 20 is connected to theattachment portion 17 by the lower hook shaped protrusion, receiving thecorresponding fastening element 21 therein. Thereby, the extension panel is allowed to pivot between a lowered position, in which it rests against a vertical side of thepanel 3, to the raised position, corresponding to pivoting theextension panel 20 by 180 degrees. To fix theextension panel 20 in the raised position, theextension panel 20 is thus pivoted 180 degrees from the lowered position and, further, slightly lifted such that the upper hook shaped protrusion of theattachment portion 17 can receive thecorresponding fastening element 21 therein. Correspondingly, to move theextension panel 20 from the raised position to the lowered position, theextension panel 20 is lifted such that the shaft portion of thefastening element 21 which is received in the upper hook shaped protrusion is released from the engagement therewith, where after theextension panel 20 can be pivoted downwards to the lowered position. In a similar manner, other accessories, for example a sign, or lighting, can be movably arranged at theattachment portion 17 of thepanel 3. However, in order to enable further accessories in conjunction with theextension panel 20, preferably they are attached to thevertical beam 14 of thepanel 3, e.g. in a similar way as theconnector 4 as will be described below, or to thegroove 8 of thebarrier 2. - Continuing with
Fig. 1 , theconnector 4 of the worksite barrier system 1 comprises apanel engagement portion 41 and abarrier engagement portion 42. Thepanel engagement portion 41 is arranged to engage with thepanel 3, and the barrier engagement portion is arranged to engage with thebarrier 2. In the exemplifying embodiment ofFig. 1 , thepanel engagement portion 41 comprises anelongated bracket 43 being C-shaped in cross-section, as shown in more detail inFigs. 2a and2b . The C-shaped bracket comprises facingbracket side walls 48 and abracket bottom wall 45 interconnecting the twobracket side walls 48, thereby forming the C-shape. The C-shapedbracket 43 further comprises a protrudingportion 44 at each of thebracket side walls 48, at their respective free ends, which are not connected with thebracket bottom wall 45. Each protrudingportion 44 protrudes in a direction towards the opposingbracket side wall 48, i.e. towards the center of the C-shape. Anelongated groove 46 is thus formed, defined by the C-shapedbracket 43 with its protrudingportions 44. Theelongated groove 46 is arranged to receive a portion of the vertically arranged H-shapedbeam 14 of thepanel 3. Thus, in a mounted position, thebracket 43 extends vertically. More particularly, to provide an engagement between theconnector 4 and thepanel 3, the C-shapedbracket 43 is arranged at thebeam structure 14 of thepanel 3 such that each protrudingportion 44 engages acorresponding recess 16 of the H-shapedbeam 14. This provides a sliding engagement between theconnector 4 and thepanel 3. - In order to fix the
connector 4 to thepanel 3 at a certain position along the vertically arrangedbeam 14, panel engagementportion fastening elements 47 are provided at thebracket bottom wall 45. The panel engagementportion fastening elements 47 are here arranged at a distance from each other along the extension of the elongated C-shapedbracket 43. Each panel engagementportion fastening element 47 is further arranged in a threaded engagement with thebracket bottom wall 45 such to extend there through and to abut against thebeam 14. A plastic spacer can be arranged between the panel engagementportion fastening element 47 and thebeam 14. Thus, by rotating each of the panel engagementportion fastening elements 47, in threaded engagement with thebracket bottom wall 45 at different positions there along, thepanel engagement portion 41 can be fixed to the vertically arrangedbeam 14 by friction. The number of panel engagementportion fastening elements 47 may, in other embodiments, be different than two, such as for example one, three or more. Thereby, a simple mounting of theconnector 4 at thepanel 3 as well as a simple height adjustment of thepanel 3 relative to theconnector 4 are provided. - In an alternative embodiment, the
panel engagement portion 41 comprises an elongated plate which extends in parallel with thepanel 3. The panel engagement portion is further arranged to be fixable to thebeam structure 14 of thepanel 3 by means of a fastening element such as a bolt, such to provide a fixed engagement therewith. - Furthermore, with reference to
Fig. 2a , the connector comprises asupport portion 50 arranged between thepanel engagement portion 41 and thebarrier engagement portion 42, and in connection therewith. Thesupport portion 50 is generally plate-shaped and has a longitudinal extension which is generally no larger than the total width of thetop portion 6 of thebarrier 2, but which is larger than the width of thegroove 8 of the barrier. When theconnector 4 is mounted at thepanel 3, the longitudinal extension of thesupport portion 50 is perpendicular to the longitudinal extension of thepanel 3. Thereby, when arranged on top of thebarrier 2 comprising thegroove 8 as previously described, thesupport portion 50 extends across thegroove 8 of thebarrier 2 and partly abuts against a top surface of thetop portion 6 thereof adjacent to thegroove 8. Thereat, thesupport portion 50 provides a support for theconnector 4 when arranged at thebarrier 2. - The
barrier engagement portion 42 extends from thesupport portion 50 in a direction which is perpendicular to the longitudinal extension thereof, and opposite to the direction in which thepanel engagement portion 41 extends from thesupport portion 50. Thus, in the mounted position, thebarrier engagement portion 42 extends vertically downwards. Thebarrier engagement portion 42 comprises a fixingdevice 49 having anoperation element 52 engaged with thesupport portion 50, and a lockingelement 58 engaged with, and operated by means of, theoperation element 52. In the exemplifying embodiment shown inFigs. 1-2 , thebarrier engagement portion 42 comprises opposing first and second barrierengagement side portions support portion 50. Aguide portion 55 extends between bottom ends of the first and second barrierengagement side portions support portion 50. In this embodiment, thesupport portion 50, the first barrierengagement side portion 53 and theguide portion 55 are formed by a metal plate which is bent such to provide the different portions. It is, however, also possible to form the three portions by welding independent plates to each other accordingly, or by any other for the purpose suitable means. - The
support portion 50 and theguide portion 55 each comprises a centrally arranged through hole. The through hole of thesupport portion 50 is axially aligned with the through hole of theguide portion 55, and theoperation element 52 extends through them and beyond. Theoperation element 52 comprises ahead 56 and ashaft 57. Thehead 56 is arranged to partly abut against a top surface of thesupport portion 50, i.e. the top surface of thesupport portion 50 which is adjacent the through hole thereof. Theshaft 57 is arranged to extend through the through holes of thesupport portion 50 and theguide portion 55 and there beyond. The engagement of theoperation element 52 with thesupport portion 50 and theguide portion 55 is such that theoperation element 52 can rotate or be turned in a screwing motion within the respective through holes. - The locking
element 58 is provided at a bottom portion of thebarrier engagement portion 42. The lockingelement 58 is here embodied by a locking plate which has a length that is larger than the width of thegroove 8 of the barrier at therecesses 10. The lockingelement 58 further comprises a centrally arranged through hole which comprises an internal thread. The internal thread is arranged such to receive a threaded portion of theshaft 57 of theoperation element 52 to form a threaded engagement therewith. Thereby, upon rotation or turning of theoperation element 52, the lockingelement 58 is rotated there around to enter therecesses 10. - The distance at which the
guide portion 55 is arranged from thesupport portion 50 is adapted such to be shorter than the distance between the top surface of thetop portion 6 of thebarrier 2 and therecesses 10 of thegroove 8 thereof. Further, the lockingelement 58 is here arranged at a portion of theoperation element 52 corresponding to the vertical position of therecesses 10 of thegroove 8 when theconnector 4 is mounted at thebarrier 2. Thereby, upon turning of theoperation element 52 by thehead 56 around its vertical axis, the lockingportion 58 can be moved between a locked position, in which it extends into therecesses 10 of thegroove 8 at an angle to, typically close to perpendicular to, the longitudinal extension of thebarrier 2, and a released position, in which it extends in a direction parallel to the longitudinal extension of thebarrier 2. When arranged in the locked position, the lockingelement 58 provides a locking of thebarrier engagement portion 42 of theconnector 4 to thebarrier 2. When, on the other hand, the lockingelement 58 is arranged in the released position, theconnector 4 can be removed from thebarrier 2. - The second barrier
engagement side portion 54 comprises astop portion 59, seeFig. 1 . Thestop portion 59 is arranged at an end of the second barrierengagement side portion 54 and constitutes a partial prolongation thereof. Thestop portion 59 is arranged to extend such that the total length of the second barrierengagement side portion 54 is less than the vertical extension of thegroove 8 of thebarrier 2, but larger than the vertical extension at which therecesses 10 of theside walls 9 are arranged. Thereby, thestop portion 59 prevents the lockingelement 58 from freely rotating about theoperation element 52 as theoperation element 52 is rotated around its vertical axis. - The embodiment described above having the
groove 8 withside walls 9 provided withrecesses 10 for providing a structure useful for obtaining the fastening of thebarrier engagement portion 42 at thebarrier 2 is just one alternative of many. Referring additionally toFig. 10 , a more generalized description of such a structure is as follows. At least one of theside walls 9 comprises first andsecond wall portions groove 8. The distances d1, d2 are measured in a direction normal to the plane, and the plane extends between anentrance opening 118 of thegroove 8 and abottom 119 of thegroove 8. For reasons of interpretation, it should be mentioned that any portion of therecess 10, such as for instance a portion of the upper horizontal wall of therecess 10 extending between the very bottom of therecess 10 and its mouth, could be regarded as thesecond portion 121, and so could therecess 10 as a whole. Use is in fact made of the difference in measures, and having some part of thebarrier engagement portion 42 engage with the side wall at one or both of the first andsecond wall portions barrier engagement portion 42 engages the side wall at least at a portion being positioned at a greater distance from the central plane A-A than thefirst wall portion 120. Some alternative side wall structures are shown inFig. 9 and will be described below. - Thus, when mounting a
panel 3 to which theconnector 4 is engaged by means of thepanel engagement portion 41 of theconnector 4, the lockingelement 58 is arranged in the released position. Thebarrier engagement portion 42 of theconnector 4 can then be arranged in thegroove 8 of thebarrier 2. Thepanel 3 can thereafter be fixed to thebarrier 2 by operating theoperation element 52 to the locked position, by turning thehead 56 of theoperation element 52 in a first direction. When turning thehead 56 of theoperation element 52 in the first direction, the lockingelement 58 is rotated into the locked position, in which it extends into therecesses 10 of thegroove 8 and engages with the walls of therecesses 10. When turning thehead 56 further, the lockingelement 58 is consequently blocked from continued rotation in the first direction. Due to the threaded engagement of the lockingelement 58 with theoperation element 52, further rotation of theoperation element 52 here from causes the lockingelement 58 to move vertically along theoperation element 52 until it is stopped from further movement by the top end of therecesses 10, whereby the lockingelement 58 is fixed in the locked position and theconnector 4 is fixed to thebarrier 2. - By turning the
head 56 of theoperation element 52 in a second direction, opposite to the first direction, the lockingelement 58 is rotated back to the released position. More particularly, the lockingelement 58 rotates until stopped by thestop portion 59, and in this position the lockingelement 58 extends in parallel with thegroove 8. Thereby, theconnector 4 can be removed from thebarrier 2. - With reference to
Fig. 4 , there is provided an alternative embodiment of the worksite barrier system 100 according to the present invention. According to this embodiment, the beam structure of thepanel 103 comprises two vertically arrangedbeams 114 extending along the height of thepanel 103 at different portions thereof, i.e. at a distance from each other. At a bottom end of eachbeam 114, abarrier receiving bracket 115 is arranged. Thebarrier receiving bracket 115 is arranged such to be able to receive a portion of thebarrier 2 extending from thegroove 8 to a front or back wall of thebarrier 2. The beam structure of this embodiment further comprises atransverse beam 116 extending between, and attached to, the two vertically arranged beams 114. - Furthermore, the
panel engagement portion 141 of theconnector 104 comprises apanel engagement post 143 comprising a hook shapedprotrusion 144. Thepanel engagement post 143 extends from thesupport portion 150 of theconnector 104 in a direction perpendicular to the longitudinal extension thereof. That is, when theconnector 104 is engaged with thebarrier 2 and thepanel 103, thepanel engagement post 143 extends vertically upwards from thesupport portion 150. The hook shapedprotrusion 144 extends from thepanel engagement post 143 in a direction towards thepanel 103, and then downwards. The hook shapedprotrusion 144 is further adapted such to partially circumvent a portion of thetransverse beam 115 of thebeam structure 114 of thepanel 103. The partial circumvention of thetransverse beam 116 by the hook shapedprotrusion 144 allows thepanel engagement portion 141 of the connector to slide along thetransverse beam 116 while providing a connection of theconnector 104 to thepanel 103. Theconnector 104 is thereby slideably connected to thepanel 103. As regards thebarrier engagement portion 142 of theconnector 104 it can be of any suitable kind, such as any of the embodiments described herein. - With reference to
Fig. 5 , there is provided yet another embodiment of the worksite barrier system 200. In this embodiment, thepanel engagement portion 241 comprises anengagement tube 243. The beam structure here comprises at least one vertically arrangedbeam 214 fastened to thepanel 203. A bottom portion of thebeam 214 is separated from thepanel 3, at least slightly, and is received in theengagement tube 243. Theengagement tube 243, as well as thebeam 214, has a cylindrical shape, but other shapes are feasible as well. This allows theengagement tube 243 to be rotated about thebeam 214, which can be advantageous for transportation and packing of thepanel 203 and theconnector 204. In addition, or alternatively, theengagement tube 243 is displaceable along thebeam 214. - The
support portion 250 is in this exemplifying embodiment arranged diagonally across thegroove 8 of thebarrier 2. -
Figs. 6-8 show further examples of the barrier engagement portion of the connector according to further embodiments of the work site barrier system. - With reference to
Figs. 6a-b , thebarrier engagement portion 342 comprises the first and second barrierengagement side portions support plate 350, as described with reference toFig. 2a . In this exemplifying embodiment, however, the first and second barrierengagement side portions engagement side portions groove 8 of thebarrier 2 of the worksite barrier system 1, such to be receivable therein. The lockingelement 358 of the fixingdevice 349 is arranged between the first and second barrierengagement side portions support plate 350, and it is movable towards and away from thesupport plate 350 but non-rotatable. The lockingelement 358 comprises a plate-shapedbase part 360, which has a threaded through hole engaged with the threaded portion of theoperation element 52, and alateral aperture 361 at two opposite ends thereof. The lockingelement 358 further comprises two lockingparts 363 hingedly attached to the first and second barrierengagement side portions first end 364 of each lockingpart 363, and movably extending through theapertures 361 to engage with therecesses 10 at asecond end 365 of each lockingpart 363. More particularly, when thebarrier engagement portion 341 is received in thegroove 8 of thebarrier 2, the ends of thebase part 360 comprising thelateral apertures 361 face oneside wall 9 each of the opposingside walls 9 of thegroove 8. Thelateral grooves 361 are generally of a substantially rectangular shape. Thefirst end 364 of each lockingpart 363 is an upper end positioned between thebase part 360 and thesupport element 350, and thesecond end 365 is a lower end positioned below thebase part 360. There is a play between the lockingpart 363 and theaperture 361. Due to the play of thelateral apertures 361, the lockingparts 363 are pivoted outwards when theoperation element 52 is rotated in the first direction. The position of thebase part 360 is such that, when thebarrier engagement portion 342 is received in thegroove 8 of thebarrier 2, the lockingparts 363 are driven by thebase part 360 to pivot outwards to engage therecesses 10 of thegroove 8 of thebarrier 2, seeFig. 6b , as a result of theoperation element 52 being rotated in the first direction. Here, the first and second barrierengagement side portions base part 360 provide stop portions preventing thebase part 360 from rotating around theoperation element 52 as it is rotated, but in both directions of rotation in contrast to thestop portion 59 above. - With reference to
Figs. 7a-b , there is provided an alternativebarrier engagement portion 442. Like in the above embodiments, thebarrier engagement portion 442 comprises afixing device 449 having anoperation element 52 and alocking element 458 operated by the operatingelement 52. However, in particular the base part 70 and the lockingparts 71 of thelocking element 458 are different. According to this embodiment, the base part 70 comprises adrive nut 72 arranged in threaded engagement with theoperation element 52. At opposing sides and extending into the space between the first and second barrierengagement side portions fastening portions 74, each holding a bottom part of amotion transferring member 73. At a top portion thereof, themotion transferring member 73 is hingedly engaged with the lockingpart 71. Here, themotion transferring member 73 is engaged with the lockingpart 71 by means of a fastening element extending through respective engagement portions thereof. - The locking
parts 71 of this exemplifying embodiment are embodied by two bent locking plates arranged between the first and second barrierengagement side portions operation element 52. At an upper portion, the lockingplates 71 are hingedly engaged withrespective hinge elements 75 extending through apertures in the first and second barrierengagement side portions portions 71 are thereby allowed to pivot around thehinge element 75. At the lower portion, the locking plates are engaged with respectivemotion transferring portions 73. - The first and second barrier
engagement side portions elongated apertures 76 extending in the vertical direction, i.e. in a direction parallel with the extension of theoperation element 52, for receiving end portions of thefastening portion 74. Theelongated apertures 76 and thecorresponding fastening portions 74 are arranged such to allow the end portion of eachfastening portion 74 to slide along the vertical extension of therespective aperture 76. Thereby, when theoperation element 52 is turned in a first direction, the base part 70, stopped from rotating with the fixing element by the first and second barrierengagement side portions operation element 52. As the base part 70 is moved upwards, themotion transferring portions 73 drive the lockingplates 71 to pivot outwardly such to protrude from between the first and second barrierengagement side portions - The base part 70 and the locking
plates 71 are arranged such that, when thebarrier engagement portion 442 is received in thegroove 8 of thebarrier 2, the lockingplates 71 engage therecesses 10 of thegroove 8 of thebarrier 2 as they are pivoted outwardly, seeFig. 7b . - Finally, referring now to
Fig. 8 , there is provided yet another example of the locking parts and the base part of thebarrier engagement portion 542. Thebase part 80 here comprises adrive nut 86, which is in threaded engagement with theoperation element 52. Thedrive nut 86 has a generally H-shaped cross section, formed by recesses 81 arranged in opposite side portions of thedrive nut 80. The recesses 81 provide sliding tracks for an operationelement engagement portion 82 of the lockingpart 83. More particularly, one of the recesses 81 is arranged in a sliding engagement with the basepart engagement portion 82. The basepart engagement portion 82 is adapted such to be received in the recess 81, having upper and lower surfaces which bear against the surfaces of the nut portions defining the recess 81. The basepart engagement portion 82 is thus allowed to slide within the recess 81 in a direction perpendicular to the extension of theoperation element 52. - The locking
part 83 of this exemplifying embodiment comprises a substantially L-shaped plate. The L-shapedplate 83 is arranged between the first and second barrierengagement side portions slidable fastening elements 84. At least one of the first and second barrierengagement side portions groove 85 for each of theslidable fastening elements 84. Theslidable fastening elements 84 are arranged to be slidable along the extension of thegroove 85, whereby the lockingplate 83 is movably engaged with the diagonally arrangedgroove 85. Thus, when thebase part 80 moves upwards along theoperation element 52 as the latter is rotated in the first direction, the lockingpart 83 is driven to slide along the diagonally arranged grooves causing the lockingpart 83 to slide outwards and to partly protrude from between the first and second barrierengagement side portions Fig. 8 . Also here, thebase part 80 is stopped from rotating together with theoperation element 52 as the latter is turned, by the first and second barrierengagement side portions - When the
barrier engagement portion 542 of theconnector 4 is arranged at abarrier 2, and thus received in thegroove 8 thereof, turning of theoperation element 52 in the first direction causes the lockingpart 83 to slide outwards to a locked position in which the L-shaped plate engages therecess 10 of the correspondingvertical side wall 9 of thebarrier 2, as seen inFig. 8 . Providing L-shaped plates at both sides of thebase part 80, such that a lockingplate 83 engages each of therecesses 10 of thevertical side walls 9 of thegroove 8 of the barrier is also possible according to an embodiment of the worksite barrier system 1. - Similarly, when the fixing
element 52 is rotated in a second direction, opposite to the first direction, thebase part operation element 52 such that the locking part is released from the engagement with therecess 10, and thereby enters the released position. Here from, theconnector 4 can be removed from thebarrier 2. - While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. The invention is not limited to the disclosed embodiments. For instance, the locking element of the embodiments shown in
Figs. 1 to 7 can be adapted such to engage a sole recess provided in one of thevertical side walls 9 of thegroove 8 of thebarrier 2. - The groove at the top portion of the barrier can have many different shapes while still working with one or more of the above-described variants of the barrier engagement portion. Some examples of alternative shapes will be described in conjunction with
Fig. 9 . Onealternative groove 90 has outwardlysloping side walls 91 in a direction from its entrance opening at the top of the barrier to its bottom. Eachside wall 91 has first andsecond portions side walls 91 at thesecond portion 93. - Another
alternative groove 94 has generallyvertical side walls 95, Eachside wall 95 is provided with aprotrusion 96 extending into thegroove 94, i.e. towards the central plane of thegroove 94. A locking element of the barrier engagement portion typically engages the protrusions at bottom surfaces 97 thereof. - Another
alternative groove 98 is similar to the just describedgroove 94, but theprotrusions 99 are arranged at the very top opening, or mouth, 123 of thegroove 98. - Another
alternative groove 124 is similar to the just describedgroove 98, but theprotrusions 125 at the top opening of thegroove 124 are sloping downwardly and inwardly of thegroove 124. - The panel engagement portion can be more permanently connected with the panel, such as by being welded to the beam of the panel. However, that is a less flexible and less advantageous solution.
- Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in practicing the claimed invention, from a study of the drawings, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that certain measures are recited in mutually different dependent claims does not indicate that a combination of these measured cannot be used to advantage. Any reference signs in the claims should not be construed as limiting the scope.
