Definitions

  • the invention relates to a fence panel comprising a frame of fence profiles, preferably tubular in form, and a wire mesh panel which is attached to the frame and covers the opening within the frame.
  • the abutting ends of these profiles form corner joints with one another, thus constituting the frame.
  • fence panels can be used for the fixed sections between the posts of a fence, but in particular they can also be used as hinged or sliding sections of a gate.
  • Fence profiles are profiles that normally have an apparent cross-section with a surface area in the range from 15 to 250 cm2, depending on whether it is a light or a heavy fence.
  • the apparent cross-section is the cross-section of the smallest convex figure that fits within the actual cross-section of the profile.
  • These profiles are usually made of steel, coated externally with a corrosion-resistant layer, for example, of zinc, lacquer or polymer.
  • the wire mesh panel covering the opening is a mesh structure of drawn steel wires or rods having a diameter which is usually in the range from 3 to 8 millimetres, these wires being firmly attached to one another in the cross-points, usually by means of welding.
  • the wire mesh panel is then also coated with a corrosion-resistant layer, for example of zinc, lacquer or polymer.
  • the frame has a rectangular shape, but it is clear that the invention is not limited to this shape, and that in general the frame can, if necessary, also have a polygonal shape, and that the profiles that form the sides of the frame do not necessarily need to be straight, provided there is a frame formed by fence profiles whose adjoining ends form corner joints with one another, these corner joints not necessarily being at right angles.
  • a frame formed by fence profiles whose adjoining ends form corner joints with one another, these corner joints not necessarily being at right angles.
  • only rectangular frames will be dealt with for the sake of simplicity, but it will be clear that the details described can be translated to analogous structures adapted for other frame shapes without going beyond the basic concept of the invention.
  • Such a frame must of itself be very stable as to its form, because such form stability is supported only to a small extent by the wire mesh covering the opening of the frame. This is especially the case when the fence panel is used as a mobile section for a gate in which the entire frame hangs with its own weight on only one side, and even more according as the horizontal dimension of the mobile gate section increases in relation to the vertical dimension.
  • the corner joints of such a frame therefore need to be very sturdily constructed in order to guarantee this form stability.
  • Corner joints can be reinforced through the use of profiles running diagonally inside the frame, but these complicate the manufacture or assembly of the frame. To achieve sufficient form stability without diagonal reinforcement, it is necessary for practical reasons to resort to welding of the profiles to one another at the corner joints. But then it becomes inpractical to assemble the frame on site. It has then to be produced in the factory on the basis of the specified dimensions and subsequently exported and transported to the wholesaler, and then further on to the fence installer who specified the dimensions.
  • standard mesh panel shapes and standard profile lengths can then be produced and sold in kit form so that the installer himself can, if necessary, adapt the dimensions by cutting the panel and sawing the profiles. But for doing this, it must be possible for him to join the profiles to one another on site with a strong corner joint in a simple manner, not by welding, and which is not time-consuming.
  • the corner joints between the ends of the fence profiles are designed as bolted joints, at least one of which having the following characteristics :
  • corner joint can be assembled on site with bolts, and is exceptionally strong. It is possible that in certain cases it would be sufficient for only one such corner joint to be constructed in this manner, and that the other corner joints of the frame could then be less strong and that they could be bolted together on site in another manner.
  • all corner joints of the frame should preferably be constructed in the manner described above under (a) to (e). The invention is not limited, however, to the fact that all corner joints must be constructed in this manner.
  • Both profile ends should preferably be of tubular construction.
  • Figure 1 shows a rectangular mobile section of a gate according to the invention.
  • Figure 2 is a detailed view of a bolted corner joint according to the invention, between two tubular profiles.
  • Figure 3 is a detailed view of a bolted corner joint, also according to the invention, between a tubular profile and a U-profile.
  • the rectangular mobile section of a gate according to Figure 1 is a fence panel containing a rectangular frame formed by four tubular fence profiles 1, 2, 3 and 4, the adjoining ends of which forming, two by two, four corner joints at right angle, for example 11, thus constituting a closed frame.
  • This fence panel further contains a wire mesh panel 5 (not completely shown), the outer edges of which being attached to the front side of the tubes, thus covering the rectangular opening within the frame, such that the fence panel blocks entry.
  • the tubes are made of steel and in this example they have a square cross-section with sides of 6 cm.
  • This fence panel is installed vertically between two vertical steel fence posts 6 and 7 which are anchored solidly in the ground, and which, in this example, are in the form of tubes with a square cross-section with 15 cm sides.
  • the vertical tubular profile 2, adjoining post 6, is provided with a pair of half hinges which engage into corresponding stationary halves attached to post 6, thus forming a pair of hinges 8 and 9.
  • the use of more than two hinges is also possible here.
  • the other vertical tubular profile 4 has a gate handle 10, or a bolt and/or a lock which fastens into the vertical post 7, which is of the same type as post 6.
  • the ends of the tubular profiles 1 and 2 are indicated by the numbers 21 and 22, respectively.
  • the respective axes 23 and 24 of the two tube ends indicate the longitudinal direction of these tube ends. These axes run through the centres of the respective cross-sections, i.e., in this example, through the point where the diagonals of the square, formed by the cross-section, intersect. In this example the two axes lie in the plane of the figure and form a right-angle with respect to one another.
  • Figure 2 is a cross-section along the plane defined by the two axes. To facilitate reading the figure, the first tube end 21 is called the "horizontal" tube end and the second tube end 22 is called the "vertical" tube end.
  • a "head” can be distinguished.
  • this "head” is the smallest convex figure that can be contained in said starting figure.
  • this head is a flat square, defined by the outside edge of the cross-section.
  • each of the tube ends is fitted with a cap 27 and 28, respectively.
  • Each of these caps comprises a head section 29 and 30, respectively, which covers the head of each tube end.
  • each of these caps also comprises a tubular shaft section 31 and 32, respectively, which extends into the tube cavity and rests without any play against the internal surface of the tube, preferably with a certain amount of pressure such that the cap of itself remains tightly jammed in the cavity.
  • the caps in this example are made of aluminum, but can also be of plastic or steel.
  • the relative position of the tube ends 21 and 22 with respect to one another is such that the head of the horizontal tube end 21 rests via the head section 29 of cap 27 against the side wall of the vertical tube end 22.
  • the head of the horizontal tube end 21 does indeed rest via the peripheral edge of the head section of cap 27 against the side wall 33 of the vertical tube end 22.
  • the place where the head section 29 of the cap rests against the side wall of the vertical tube end has the shape of a simple flat square.
  • the horizontal tube end can have a different cross-section, with the place where it rests against the side wall of the vertical tube end then having a different shape, as for example a circle when the horizontal tube end has a round cross-section.
  • the vertical tube end too can have a different cross-section, for example round, with the place where the horizontal tube end rests against the side wall of the vertical tube end then having a more complicated, non-flat shape, but where the head of the horizontal tube end and the head section 29 of the cap then have a modified form which rests equally well against the side wall of a vertical tube end having a round cross-section.
  • the two tube ends have square cross-sections of equal dimensions.
  • the corner joint further comprises two steel bolts 34 and 35, which are intended to take up a great deal of force.
  • Each of these bolts comprises a head 36, a shaft section 37 and a threaded end 38.
  • the head 36 of the bolt is situated on the external side of the vertical tube end, on the side diametrically opposite the point where the horizontal tube end rests against the side wall of the vertical tube end.
  • the shaft section of the bolt runs from here along an axis 39, which has the same direction as the axis 23 of the horizontal tube end, straight through the vertical tube end 22 and straight through the shaft section 32 of the cap 28.
  • this vertical tube end comprises a pair of openings 40 and 41 situated diametrically opposite one another, while the shaft section 32 of cap 30 also comprises a pair of openings 42 and 43 situated diametrically opposite one another, intended for the shaft section of the bolt 34 to pass through.
  • This shaft section then runs further through into the internal space of the horizontal tube.
  • cap 27 comprises an opening 44 in its head section to allow the shaft of bolt 34 through.
  • the shaft section of the bolt then ends in the internal space of the horizontal tube and passes into the threaded end 38 of the same bolt, which is screwed tight in a threaded opening 45 in a steel pin 46.
  • This pin can also be made of plastic.
  • Bolt 35 has an identical structure and runs through the corner structure in the same way as bolt 34, though parallel with it.
  • the vertical tube end and the shaft section of the cap 28 must once again comprise like pairs of openings to let this bolt through, and the cap 27 must also have an opening for this purpose.
  • the axes of the bolts lie in one and the same plane, which includes the axis of one of the bolts and which is parallel with the axis 24 of the vertical tube end, i.e. in the plane of the figure in this example.
  • the axis of pin 46 runs perpendicular to the axes of the bolts and in the plane of these axes, i.e. in the plane of the figure in this example.
  • this tube end comprises a pair of openings 47 and 48 situated diametrically opposite one another, and the cap 27 of the horizontal tube end also comprises a pair of openings 49 and 50 for this purpose situated diametrically opposite one another.
  • a number of parallel threaded openings run through the pin, one for each bolt, such as opening 45 for bolt 34. These openings are threaded, and the threads of the corresponding bolts fit into them.
  • the bolts 34 and 35 must be sufficiently tightened, thus pressing the head of the horizontal tube end forcefully against the vertical tube end.
  • the weight F of the gate itself acting in the direction of the downward arrow 52 which, due to the effect of leverage, develops a very large bending moment against the side wall of the vertical tube end where it is in contact with the head of the horizontal tube end. Because of this, the lower side of the head of the horizontal tube end is pressed even more forcefully against the vertical tube end.
  • the head section 29 of cap 27 does indeed ensure that the pressure force exerted by the edge of the horizontal tube end does not act directly on the side wall of the vertical tube end, but rather is distributed over the vertical tube end.
  • the pin and the corresponding openings must therefore be made large enough to avoid damage to the edges of this opening due to excessive pressure force. These openings must also be located sufficiently far from the head of the horizontal tube end so that the pin will not tear through the opening towards the head of the horizontal tube end.
  • the bolts 34 and 35, the pin 46, and the tubular reinforcements 51 are parts which have to withstand strong forces. They must therefore be made of steel or another material of equivalent strength.
  • the cap 28 can be very useful, however, because it can greatly facilitate the assembly of the tubular reinforcements 51, since during assembly these tubular reinforcements need to be brought into position and held fast in order for the bolts to be passed through them. With the vertical cap 28 this is simple.
  • the shaft section 32 of this cap comprises indeed pairs of openings 42 and 43, situated diametrically opposite one another for allowing a corresponding bolt 34 to pass through each pair of openings.
  • tubular reinforcements 51 are first inserted into the openings 42 and 43 of the vertical cap, and only then is the cap inserted into the vertical tube end. Thus these tubular reinforcements are brought into position and held in position by the cap.
  • tubes have been used in which an "axis" can be distinguished in each tube, i.e. a longitudinal line through the centre of the cross-section, and these axes intersect one another in the plane of the figure.
  • an "axis" can be distinguished in each tube, i.e. a longitudinal line through the centre of the cross-section, and these axes intersect one another in the plane of the figure.
  • a central axis should be discernable in the tube ends, or that for this purpose any cross-sectional form is required with any kind of symmetry in which a centre can be distinguished for the purpose of defining an axis.
  • these axes need not run in the same plane and intersect with one another. It is only the longitudinal directions that are important, and it must be possible to distinguish them in order to determine the direction in which the axis of the bolts and of the pin should run.
  • the bolt head 36 should lie diametrically opposite the place where the side wall of the second tube end rests against the head of the first tube end 21. This means that the bolt head 36 and the head of the first tube end rest against parallel surfaces which are perpendicular to the axis of the bolt 34. It is also necessary that the pairs of openings 40 and 41 in the vertical tube end and the pairs of openings 42 and 43 in the shaft section of the vertical cap, as well as the pairs of openings 47 and 48 in the horizontal tube end and the pairs of openings 49 and 50 in the shaft section of the horizontal cap, should lie "diametrically" opposite one another, i.e. openings in parallel surfaces and with a connecting line running perpendicular to these surfaces.
  • the installer himself can shorten them on site as required, bore the openings along the side where they have been shortened and place the caps on the tube head. In this way he is able to receive a gate or fence panel in separate pieces or kit form and then make the necessary adjustments and assemble the parts himself using simple tools.
  • the first profile end 21 used was tubular in form.
  • This first profile end can be of any profile form, provided the cross-section includes two profile parts which are located diametrically opposite one another. This means that on the two opposing sides of the cross-section there should be two profile parts, either straight or in the form of a curve, but in general running parallel in relation to one another, such that openings diametrically opposite one another can be made in them, analogous with openings 47 and 48, through which the pin 46 can be pushed.
  • Examples here include a U-profile or a T-profile.
  • openings situated diametrically opposite one another means: openings in surfaces running parallel to one another and having a connecting line perpendicular to these surfaces.
  • the two profile parts then have a space between them which is defined as the "internal space” of the profile end, in which the shaft section 37 and threaded end 38 of the two bolts 34 and 35 run into the pin 46.
  • these two profile parts have two surfaces facing one another which are defined as the “internal surface” of the profile end and against which the shaft section of the cap 27 will rest. If this profile is not a tube, this shaft section may not of itself remain tightly jammed in the profile.
  • this head has a square form
  • the head section of the cap 27 has a square form.
  • a second profile end having a form other than tubular is also possible.
  • this profile end 22 has a tubular form, as in Figure 2, the passageway for each of the bolts 34 and 35 is defined by the openings 40 and 41, situated diametrically opposite one another, and by the tubular reinforcement 51 between the two.
  • This entire passageway is constructed so as to possess a compressive resistance in the longitudinal direction which is of the same order of magnitude as the tensile resistance of the shaft section of the corresponding bolt 34, because it is this passageway that will have to effect the reactive force against the tensile force in the bolt.
  • same order of magnitude is meant not less than about 0,3 times the tensile resistance of that bolt.
  • a tubular form with two openings situated diametrically opposite one another and a tubular reinforcement between them.
  • a cross-sectional form can be used, such as for the first profile end, which includes two profile parts situated diametrically opposite one another, for example a T-profile or a U-profile, with two openings situated diametrically opposite one another, analogous with openings 40 and 41, and a tubular reinforcement between them. Then the external side of the one profile part is placed against the head of the first profile end and the bolts are introduced along the external side of the other profile part. But it can be done in yet another way.
  • the cross-sectional form of the second profile end 22 should have a profile part 61 that can be placed against the head of the first profile end 21. And the latter need not necessarily be a tubular form as in Figure 3, provided the profile fulfils the aforementioned criteria set for the first profile end.
  • the passageway through the entire second profile end is thus formed simply by such an opening 62 or 63.
  • This passageway needs no tubular reinforcement in order to have by itself a compressive resistance in the longitudinal direction which is at least equal to the tensile resistance of the shaft section of the bolt 34.
  • this compressive resistance is effected by the steel of the profile section 61 around the opening 62.
  • a U-profile and even an L-profile can be used for the second profile end.
  • the middle side that forms the connection in the U-form is utilized for preference as profile section 61, in which the passage for the bolts 34 and 35 is formed by the openings 62 and 63, respectively, in this profile section 61.
  • a U-profile can for example be used for the lower horizontal fence profile 1 of the frame around the panel, as well as serving as a rail for guide wheels.
  • a cap can be provided for every other profile form, having a head section that covers the head of this second profile end and a tubular shaft section that extends into the tube cavity and rests without any play against the internal surface of the tube.
  • This cap can, for example, be attached by the bolts 34 and 35 to the second profile end.
