Description
A panel having connector means for forming a composite sports ground for e. g. skating, bowling and the like, and method of assembling such sports ground The present invention relates to a sports ground (surface) to be assembled from separate panels, for e. g. skating, bowling and the like; in particular, the invention relates to a panel having at the edges connector means for interconnecting or joining separate panels, as well as a method of assembling a sports ground or (running) course from such panels.
Conventional running courses or sports grounds of ! plastic are produced from individual sections in order to facilitate transportation to the assembling site.
The separate sections are connected to each other by welding. Assembling and connecting involves a rela-tively high expense of time so as to result in extremely high cost.
,' : , It is an object of the present invention to provide components for assembling a sports ground (surface), preferably from plastics material, which greatly -, ~, .
~ '31~6 , ~
reduces or even eliminates the expenses for maintenance and service and the construction of which is of such type that a perfectly planar sports ground surface is obtained. For example, skating-rinks require to be constantly maintained and serviced, and relatively high expenses are required for properly cooling the skating-rink particularly in summer. The invention contemplates to at least substantially reduce all these costs.
Further, it is an object of the present invention to form the separate panels in such a way that extra clamping elements are not necessary, while nevertheless permitting the panels to be assembled into a course or a large-area sports ground.
According to the present invention, this object is solved in that said panel includes, in the Y direction, means to form a groove and tongue joint with an adjacent panel, that a connection or joint preventing displacement is provided between adjacent panels in the direction, which connection comprises a recess or groove (Figure 3) formed in the panel edge of one of the adjacent panels and above which a protruding nose or lug is provided which joins said recess through an inclined face, such ~, . ~,~
~ , . . . .
;'31(~t;
that said recess defines a cavity having the shape of a truncated wedge surface, and that between said recess and said panel edge there is provided a raised part the upper edge of which extends in parallel with the panel surface and which terminates in an inclined face in front of said recess and that the edge configuration of the adjacent panel is such that this panel engages into the edge configuration of the firstmentioned panel in such a manner that, for example, the projection engages into said recess of said firstmentioned panel, so as to define between both panels a joint preventing displacement between both panels (Figure 5) and that, furthermore said edge has formed therein in the X direc-tion in front of the end face of said panel, a recess approximately in the region of the neutral zone of said panel, with a clip or clamp being adapted to be driven into said recess, which clamp simultaneously engages into a corresponding or complementary recess of the laterally adjoining panels, so as to form a clamping connection between the adjacent or adjoining panels in X direction. An other embodiment is characte-rized in that a groove or indentation is each provided in front of said recess, said groove or indentation allowing a clamp to be driven into the panel(s).

11~i91CP6 According to a further embodiment, the invention is characterized in that the proiled or sectioned edges of the panel, acting as connecting means, are provided on all edges with the exception of the edge panels, whereby a junction cross of the groove-shaped recesses is formed at the corners of the panels.
The technical advance of the invention resides in the fact that problems in the production of the panels, regarding their shape and the connector means, are avoided, and that assembly of the sports ground is extremely easy, while the panels are secured to each other in such a manner that relative displacement cannot occur. As the panels forming the sports ground are made of plastics material, the sports ground requires little maintenance. It is sufficient that the sports ground is periodically cleaned from dust and dirt.
Expediently, the panels are laid on a solid substrate which may consist of concrete or macadam. In many instances, it may be advantageous to interpose an elastic layer between the plastic panels and the sup-porting surface, which layer may be formed, for instance, from plastic foam.
~; , lt~;~iO~
The art of preparation of plastlcs materlals has rea-ched such an advanced state that it is readily possible to employ a plastics material which can withstand even the stresses exerted by skating.
In one embodiment of the invention, the inclined faces which laterally define the recess provided in the panel, are of different inclinations so as to form a wedge-shaped recess, preferably of such configuration that one inclined face has a greater inclination than the other inclined face. In this embodiment~the panels may be locked on each edge thereof without the use of special clamping means.
In still another embodiment which does not utilize a wegde-type clamping effect, the panel edge in the area of the panel surface includes a greatly protruding nose or lug having the front portion of the lower side thereof provided with a recess the front end face of which is defined by an inclined face, said inclined face joining a surface extending in parallel with the upper edge of the panel such that the thus formed pro-truslon defines a nose or lug the lower side of which joins a surface extending in parallel wlth the upper U~
edge of the panel and which, finally, includes a fuxther nose or lug at the tip thereof, while the ad-jacent panel is provided with a recess acting to re-ceive the protrusion of the (first) panel and which, further, includes at the front portion thereof a projection originating from an inclined face and engaging into the recess of the other (opposite) panel.
In one embodiment of this edge configuration, the recess formed in one panel shows at the inner end thereof a vertical surface above which an outwardly protruding nose or lug having horizontal and vertical end faces, so as to define an approximately rectangular recess into which the other (opposite) panel engages. This edge configuration offers the possibility to join the panels to each other in either direction without the use of specific clamping elements. This configuration i8 of particular advantage for the reason that slight variations from the contemplated shape of the edge configuration are insignificant, such that this edge configuration is particularly well suited for panels made of plastics material.
In a third embodiment being principally similar to the second embodiment, both panel edges are provide~ with , ~ '31~ ~
an arc-shaped or curved recess or a curved projection, respectively, which are engaged with each other in assembling the panels. This embodiment provides for further facilitated joining of the panels.
Needless to say, all embodiments of the invention offer the possibility of joining the panels in only one direction or in either direction, such that courses of lesser width or even sports grounds of greater area may be assembled as desired.
According to the present invention, joining of the panels is performed by initially providing a separate panel, then insertlng a second panel, in inclined po-sition, into the groove of said first panel, subsequently engaging, while maintaining said inclined position, a third panel into said second panel, and upon joining said second and third panels in their inclined position, simultaneously lowering both panels into a horizontal position, etc..

Obviously, panel edges X according to Figures 12 and 13 may be joined by havlng projection 40' engage into the left hand recess according to Figure 13, when the panel is rotated about 180 in Figure 12. Figures 14 and 16 illustrate in side eleva-tional view the actual configuration of the panel edges, and Figure 16 shows particularly the manner in which the panels are joined. The upper panel, the upper part of which is designated with numeral 32, includes a recess 37 into which the projection 37' accordinq to Figure 15 engages such that nose or lug 40' engages into recess 40 of Figure 14. As appears from the view, the inclined faces 39 and 43 are of different degrees of inclinations, such that the incli-nation of face 43 is steeper. In this manner, the side faces of recess 37 are imparted a wedge-shaped configu-ration which could be readily seen in faces 39 and 43 of the Figure were extended. Numeral 41 in Figure 14 indicates a projection engaging into recess 41' of Figure 15 when the panels are joined together. Upon joining, face 36 of Figure 14 and face 36' of Figure 15 are precisely matched to each other. The lower surface of the panel is shown at 33 in Figure 14. Nume-ral 42 of Figure 14 indicates that part which tightly '.

or sealingly engages the complementary inclined face 41' of Figure 15. Numeral 38 designates the vertical upper abument face.
Figure 17 illustrates the method steps for joining three separate panels 1, 1' and 1". The process starts with the insertion of panel 1' into the groove-shaped recess of panel 1 in the direction of arrow 63. Panel 1' is initially held in the illustrated inclined position such that panel 1" may be inserted into the recess of panel 1' in the direction of arrow 64. Then, panel 1" is slightly rotated in the direction of arrow 65, whereupon this panel is slightly rotated in the directions of arrows 65 and 66 until both panels 1' and 1" assume the same inclined position. Hereupon, both panels 1' and 1" may be lowered in the direction of arrow 67 until they assume the horizontal plane of panel 1. In the above described manner, a sports ground may be assembled from the panels. In general, assembling will be made such that the joints of the various strips (of panels) are staggered symmetrically.
' ' Figures 18 to 20 schematically show the second embodi-ment of an edge structure or configuration. In order to ~ 16 -facilitate the presentation, only the edge structure as such is shown while the remaining portion of the panels is omitted. This embodiment differs from the preceding embodiment in that means providing a wedge-type effect could be omitted. Panel edge 50 includes an upper elongated projection 51, 52. A recess 53 is pro-vided in portion 51. The projection of portion 52 is of increased thickness. Both protions 51 and 52 join each other through an inclined face 54 such that the other (opposite) panel 60 may engage into recess 53 with a complementary projection. Panels 60 has a correspondingly formed projection on the lower side, which projection forms a recess in portion 58 such that panel 50 may have a nose or lug 55 engaging into a recess 56 of panel 60 above which a rectangularly formed ~rojection 57extends. Engagement of projection 55 into recess 56 provides for secure anchoring between both panels 50 and 60. The presentation of Figure 19 shows particularly that the panels 50 and 60 may be joined to each other in extremely easy manner.
Figures 21 and 22 show an embodiment which is slightly different from the above described embodiment according to Figures 18 to 20. With respect to the structure igl~f~
shown in Figures 21 and 22, reference is made to Figure 23. Thus, the presentation of Figure 21 corresponds to the viewing direction C in Figure 23, while the illustra-tion of Figure 22 is as seen in the direction D of Fi-gure 23. As appears from a comparsion with the views of Figures 18 to 20, this modification differs from Figures 18 to 20 by the feature that the projection 55, 56 is of substantially rectangular configuration. In order to facilitate the comparsion, the respective edge struct-ures are designated with 50' and 60'. The modified embodiment of a panel according to Figure 23 is desig-nated with numeral 70.
A final embodiment of an edge structure is shown in Figures 24 to 26. In this embodiment, joining of the panels is greatly facilitated in that panels 71 and 77 engage into each other with a curved recess 74 and a complementary projection 80, and panel 77 is provided with a projection 81 which engages into a complementary recess below the projection 72 of panel 71. In the case of panel 71, the recess 74 joins a projection 75 engaging into a recess 79, with both panels 71, 77 being provided with vertical end faces 78. The provision of the curved recess 74 and of the complementary projection 80 greatly facilitates insertion of panel 77.

According to Fi-gure 10, a further connection or joint is provided wherein there are provided approximately in the area of the - neutral fiber (in fiber direction), a groove 26 in one ; panel and a key 27 in the other panel, which elements are dimensioned ao as to fit into each other with tight fit. Recesses or grooves 28 for receiving a clamp 29 are provided on the lower side of the panels.
It is also possible to produce, by mirror high frequency or electrode welding, transverse joints the length of which should be 1 meter at most.
Figure 11 is a plan view of another panel 1, with the edge structures being shown in greater detail in Figures 12 to 16. As can be seen, the profiied or sectioned structures are provided on either of the four panel ed-ges. as appears from the view in direction A according to Figure 12 and from the view in dlrect10n ~ according : .

.'` ' " ' 1.1~;'316~6 to Figure 13. Obviously, panel edges X according to Figures 12 and 13 may be joined by havlng projection 40' engage into the left hand recess according to Figure 13, when the panel is rotated about 180 in Figure 12. Figures 14 and 16 illustrate in side eleva-tional view the actual configuration of the panel edges, and Figure 16 shows particularly the manner in which the panels are joined. The upper panel, the upper part of which is designated with numeral 32, includes a recess 37 into which the projection 37' accordinq to Figure 15 engages such that nose or lug 40' engages into recess 40 of Figure 14. As appears from the view, the inclined faces 39 and 43 are of different degrees of inclinations, such that the incli-nation of face 43 is steeper. In this manner, the side faces of recess 37 are imparted a wedge-shaped configu-ration which could be readily seen in faces 39 and 43 of the Figure were extended. Numeral 41 in Figure 14 indicates a projection engaging into recess 41' of Figure 15 when the panels are joined together. Upon joining, face 36 of Figure 14 and face 36' of Figure 15 are precisely matched to each other. The lower surface of the panel is shown at 33 in Figure 14. Nume-ral 42 of Figure 14 indicates that part which tightly '.

or sealingly engages the complementary inclined face 41' of Figure 15. Numeral 38 designates the vertical upper abument face.
Figure 17 illustrates the method steps for joining three separate panels 1, 1' and 1". The process starts with the insertion of panel 1' into the groove-shaped recess of panel 1 in the direction of arrow 63. Panel 1' is initially held in the illustrated inclined position such that panel 1" may be inserted into the recess of panel 1' in the direction of arrow 64. Then, panel 1" is slightly rotated in the direction of arrow 65, whereupon this panel is slightly rotated in the directions of arrows 65 and 66 until both panels 1' and 1" assume the same inclined position. Hereupon, both panels 1' and 1" may be lowered in the direction of arrow 67 until they assume the horizontal plane of panel 1. In the above described manner, a sports ground may be assembled from the panels. In general, assembling will be made such that the joints of the various strips (of panels) are staggered symmetrically.
' ' Figures 18 to 20 schematically show the second embodi-ment of an edge structure or configuration. In order to ~ 16 -facilitate the presentation, only the edge structure as such is shown while the remaining portion of the panels is omitted. This embodiment differs from the preceding embodiment in that means providing a wedge-type effect could be omitted. Panel edge 50 includes an upper elongated projection 51, 52. A recess 53 is pro-vided in portion 51. The projection of portion 52 is of increased thickness. Both protions 51 and 52 join each other through an inclined face 54 such that the other (opposite) panel 60 may engage into recess 53 with a complementary projection. Panels 60 has a correspondingly formed projection on the lower side, which projection forms a recess in portion 58 such that panel 50 may have a nose or lug 55 engaging into a recess 56 of panel 60 above which a rectangularly formed ~rojection 57extends. Engagement of projection 55 into recess 56 provides for secure anchoring between both panels 50 and 60. The presentation of Figure 19 shows particularly that the panels 50 and 60 may be joined to each other in extremely easy manner.
Figures 21 and 22 show an embodiment which is slightly different from the above described embodiment according to Figures 18 to 20. With respect to the structure igl~f~
shown in Figures 21 and 22, reference is made to Figure 23. Thus, the presentation of Figure 21 corresponds to the viewing direction C in Figure 23, while the illustra-tion of Figure 22 is as seen in the direction D of Fi-gure 23. As appears from a comparsion with the views of Figures 18 to 20, this modification differs from Figures 18 to 20 by the feature that the projection 55, 56 is of substantially rectangular configuration. In order to facilitate the comparsion, the respective edge struct-ures are designated with 50' and 60'. The modified embodiment of a panel according to Figure 23 is desig-nated with numeral 70.
A final embodiment of an edge structure is shown in Figures 24 to 26. In this embodiment, joining of the panels is greatly facilitated in that panels 71 and 77 engage into each other with a curved recess 74 and a complementary projection 80, and panel 77 is provided with a projection 81 which engages into a complementary recess below the projection 72 of panel 71. In the case of panel 71, the recess 74 joins a projection 75 engaging into a recess 79, with both panels 71, 77 being provided with vertical end faces 78. The provision of the curved recess 74 and of the complementary projection 80 greatly facilitates insertion of panel 77.
